Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery waste liquid treatment, in particular to a device for detecting material leakage in a filter press in the lithium battery industry. Background Art

[0002] Filter presses perform the initial drying process for lithium battery cathode materials, and filter cloth is a crucial component of these machines. Over time, due to factors such as raw material corrosion, extrusion, and air drying, the filter cloth can become enlarged and damaged during filtration, leading to material leakage. Material leakage during production not only wastes raw materials but also impacts production schedules. Furthermore, the mixing of material with the filtrate wastewater can cause excessive levels of heavy metals in the wastewater.

[0003] At present, the detection of defects such as cracks, scratches, and corrosion on the filter cloth surface during actual production mainly relies on subjective visual inspection of the outer surface of the filter cloth by production personnel and weight comparison of upstream and downstream processes, and observation of the filtrate color through a test mirror. This result is greatly affected by the subjective conjecture of production personnel, and there are many problems such as a high missed detection rate and increased labor costs.

[0024] This utility model provides a device for detecting material leakage in filter presses in the lithium battery industry. The device uses a densitometer to monitor the density of wastewater in real time and transmits the density to a host computer via a 4-20 mA signal. An alarm monitoring program is then developed on the host computer based on density changes. When the upper density limit exceeds a set time, an alarm device is triggered to alert production personnel to on-site inspections and to monitor material leakage from the filter cloth. If the upper and lower limits exceed a set time, an interlocking program is triggered to stop the extrusion and drainage operation, simultaneously triggering an alarm device to remind the operator to replace the filter cloth.

[0025] Figure 1 The following is a schematic diagram of a device for detecting material leakage in a filter press in the lithium battery industry according to the present invention. Figure 1In this embodiment, a device for detecting material leakage in a filter press in the lithium battery industry includes a main body comprising a feeding mechanism 100, a filter press 200, a water pressure mechanism 300, and a detection mechanism 400. The discharge end of the filter press 200 is connected to a discharge pipe and a wastewater tank 220 connected to the end of the discharge pipe. A discharge valve 210 is provided in the middle section of the discharge pipe.

[0026] The feeding mechanism 100 feeds the liquid in the liquid kettle 110 into the filter press 200 through the feed pump 120. Specifically, the discharge end of the feeding mechanism 100 is connected to the filter press 200. In this embodiment, the feeding mechanism 100 includes the liquid kettle 110 and the feed pump 120 connected to the liquid kettle 110. In this embodiment, the outlet of the feed pump 120 is provided with a feed pipe 121, and a feed valve 122 is provided in the middle of the feed pipe 121.

[0027] The water pressure mechanism 300 delivers water into the filter press 200 via the squeezing water pump 320. Specifically, the water pressure mechanism 300 squeezes water into the filter press 200. In this embodiment, the water pressure mechanism 300 includes a squeezing water station 310 and a squeezing water pump 320 connected to the squeezing water station 310. A squeezing water pipe 311 and a reflux valve 312 disposed in the middle of the squeezing water pipe 311 are disposed between the squeezing water station 310 and the filter press 200. A squeezing valve 321 is disposed between the squeezing water pump 320 and the filter press 200.

[0028] The detection mechanism 400 detects the wastewater density through the density meter 410, processes the wastewater density data by running the alarm monitoring program in the host computer 420, and uses the alarm device 430 to remind. Specifically, the detection mechanism 400 detects the discharge wastewater density of the filter press 200. In this embodiment, the detection mechanism 400 includes a density meter 410 arranged between the discharge valve 210 and the wastewater tank 220, a host computer 420 electrically connected to the density meter 410, and an alarm device 430 electrically connected to the host computer 420.

[0029] Combine Figure 1, a device for detecting material leakage in a filter press in the lithium battery industry according to this embodiment, and the specific use process is as follows: first, open the feed valve 122, start the feed pump 120, and pump the liquid in the liquid kettle 110 into the filter press 200 through the feed pipe 121. At this time, the filter press 200 is ready to close the feed pump 120 and the feed valve 122. Open the discharge valve 210, the extrusion valve 321, and the extrusion water pump 320. At this time, the extrusion water from the extrusion water station 310 is pumped into the filter press 200 through the extrusion water pipe 311 to start extrusion. The filtrate water will be discharged through the discharge pipe and discharged into the wastewater tank 220 through the density meter 410. The density meter 410 monitors the density of the discharge wastewater in real time and transmits the density to the host computer 420 through a 4-20 mA signal until the entire extrusion and discharge process is completed. When material leakage occurs during the extrusion and discharge process, the density of the discharge wastewater will increase. The density of the wastewater is proportional to the amount of material lost; the greater the amount of material lost, the higher the density. An alarm monitoring program was developed on host computer 420 based on density changes. If the upper density limit exceeds a set time, alarm device 430 will trigger, alerting production personnel to conduct on-site inspections and monitor filter cloth material loss. If the upper and lower limits exceed a set time, an interlocking program will be triggered to stop the extrusion and drainage process, simultaneously triggering alarm device 430 to alert the operator to the need to replace the filter cloth.
