How to troubleshoot a stopped scraper
Release time:
2022-12-30 14:50
Accidents are inevitable, and many situations are unpredictable. In the operation of the scraper, if a sudden interruption occurs, immediately turn off the power, then check for common reflection failures, and check which component is broken. Replace what needs replacing, and repair what needs repairing. After clearing all components, restart the detection.
If it is a large-area scraper, there is a button on the installation equipment. When the machine equipment encounters an emergency, immediately press and hold the stop button to make the scraper stop running immediately. If this situation is resolved, restart the scraper. For the sludge pump, turn the arrow symbol on the emergency stop button to make the button float upwards, then restart the sludge scraper. During the operation of the scraper, the actual operator should always pay attention to the running status of the scraper. If any abnormality occurs, stop immediately and check the cause. After the common faults are cleared, it can be restarted to check whether all the equipment is normal. Apply grease regularly at specific locations.
If, during normal use, it is found that the scraper starts or delays operation, the fault detection should be checked immediately. The key reason is that the common fault of the scraper diaphragm pump cannot start; check whether the steam filter and humidification equipment are running normally. If there are any abnormalities, they should be replaced immediately.
Check if there is debris or other objects blocking the valve inlet at the bottom of the air valve; check if the energizing shaft is damaged, or if the components are moving or stuck, and adjust the components. After adjusting according to these aspects, the scraper can be restored.
The entire scraper equipment should include: motor drive system software (including reducer, motor and overvoltage protection system software); working bridge; management center support; equipped with stainless steel sink perforated pipes and side skirts; outlet weir; desludging system software (including flushing equipment); support frame; sludge collection pipe; truss structure layout and casing type sludge valve, control cabinet and its safe and reasonable operation precautions.
When the scraper is put into use, it is necessary to increase the proportion of tap water and reduce the cleaning time of tap water. The purpose is to reduce the level of membrane environmental pollution in the equipment. Remember to close the front valve when it is temporarily not needed to start. If it is not opened for a long time, the equipment needs to be treated and cleaned. Its key role is to avoid the impact of long-term adhesion of residues on mechanical equipment. It is easy to pollute the environment in later use.

Practical application of IC tower in food processing wastewater treatment
Wastewater from the food processing industry contains a large amount of organic matter, suspended solids, and oils. Traditional treatment methods often face problems such as high energy consumption and long processing cycles. The IC tower (internal circulation anaerobic reactor), with its unique internal circulation structure and three-phase separation system, demonstrates technical adaptability in treating high-concentration organic wastewater. The core advantage of the IC tower lies in its internal circulation mechanism. Through the fluid movement of the internal rising and falling pipes, it achieves thorough mixing of sludge and wastewater, improving biodegradation efficiency. In food wastewater treatment, the IC tower can adapt to influent conditions with a wide range of COD concentrations, especially suitable for the dairy, meat processing, and brewing industries. Practice has shown that when treating oily wastewater, the IC tower can stably achieve a COD removal rate that meets emission standards by reasonably controlling the hydraulic retention time and organic load. In an actual engineering case, a large seasoning production enterprise used the IC tower as a pretreatment unit. The influent COD concentration ranged from 8000-12000mg/L, and after treatment by the IC tower, it was reduced to below 1500mg/L, significantly reducing the burden on the subsequent aerobic treatment unit. The operating data shows that the biogas yield of the IC tower is stable and can be used for energy recovery, further reducing treatment costs.
The effectiveness of IC tower in treating high-concentration organic wastewater
The IC tower (internal circulation anaerobic reactor) is an important piece of equipment in modern wastewater treatment, demonstrating significant technical characteristics in treating high-concentration organic wastewater. Its unique internal circulation system enhances the contact efficiency between sludge and wastewater, making the organic matter degradation process more thorough and showing clear adaptability in treating industrial wastewater with a COD concentration exceeding 3000 mg/L. The treatment effect of this technology is mainly reflected in two dimensions: organic matter removal rate and biogas production. Actual operating data shows that in wastewater treatment for industries such as brewing and food processing, the IC tower usually maintains a high COD removal rate. The granular sludge formed inside the reactor has good settling performance, ensuring the stability of system operation. When the temperature is controlled around 35℃, the microbial activity reaches an optimal state, and the treatment effect is relatively ideal. In the process of treating high-concentration organic wastewater, the volumetric loading capacity of the IC tower is a key indicator that distinguishes it from traditional anaerobic processes. Due to its multi-stage reaction zone design and internal circulation flow pattern, the equipment can withstand high organic load shocks. Pharmaceutical wastewater treatment cases show that the system can still maintain stable operation when the influent COD fluctuates between 5000-8000 mg/L.
In the back-end process of semiconductor manufacturing, the IC handler (integrated circuit testing and sorting equipment) plays a core role in verifying chip functions and screening for quality. Its working principle is to use a precision robotic arm to send wafers or packaged chips to the testing station, and use the probe card and tester to complete the electrical parameter measurement. Then, according to the test results, it automatically sorts out qualified products and defective products. This integrated "test-judgment-sorting" process makes it a decisive link in the quality control before the chip leaves the factory. From a technical perspective, the gatekeeping role of the IC handler is reflected in three dimensions: First, the contact testing scheme can simulate the actual working state of the chip and detect physical defects such as open circuits, short circuits, and leakage; second, the multi-station parallel testing architecture achieves the screening capacity of thousands of chips per unit time, matching the production capacity needs of the packaging and testing factory; more importantly, its test data is directly related to the yield statistics of the chip, providing key evidence for process improvement. Current mainstream equipment supports environmental temperature testing from -40℃ to 150℃, covering the reliability verification needs of different application scenarios such as consumer electronics and automotive electronics. In industrial practice, the testing standards of IC handlers are often more stringent than the terminal application conditions. Taking the case of a major packaging and testing factory as an example
