DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

The scissor-type lifting frame 52 and the U-shaped scraper 4 located in the same reaction chamber 21 are hingedly connected. The telescopic rods on both sides of the double-headed cylinder 51 are controlled to contract to drive the scissor-type lifting frame 52 to expand. When the scissor-type lifting frame 52 is expanded, the U-shaped scraper 4 is pushed downward to scrape off the dirt on the inner wall of the electrolytic cell 2 and the side wall of the diaphragm 3. The telescopic rods on both sides of the double-headed cylinder 51 are controlled to extend to drive the scissor-type lifting frame 52 to close. When the scissor-type lifting frame 52 is closed, the U-shaped scraper 4 is pulled upward to reset. The upper part of the inner wall on the left and right sides of the electrolytic cell 2 and the upper part of the left and right side walls of the diaphragm 3 are connected to the cover body 22 used to cover the electric scissor-type lifting frame 5 to The movable scissor-type lifting frame 5 is covered and protected. A discharge channel 6 is connected to the left side of the bottom of the electrolytic cell 2. The bottom of the electrolytic cell 2 is of a low-middle and high-outer inclined design to guide the electrolyte and impurities to the middle of the bottom of the electrolytic cell 2. Two plugging plates 7 are symmetrically slidably provided in the lower part of each reaction chamber 21. The plugging plates 7 are slidably matched with the adjacent diaphragms 3. The plugging plates 7 extend out of the electrolytic cell 2. A driving component for driving the plugging plates 7 to open and close is provided in the frame 1. The driving component includes two front and rear connecting plates 8 slidably arranged in the frame 1. The connecting plate 8 is U-shaped. The connecting plate 8 is connected to the plugging plate 7 on the same side thereof. The plugging plate 7 is located in the U-shaped connecting plate 8 connected thereto. The U-shaped connecting plate 8 is slidably sleeved on the outside of the electrolytic cell 2. The left and right sides of the frame 1 Two electric slide rails 9 are symmetrically connected to the wall front and back, and the slider on the electric slide rail 9 is connected to the connecting plate 8 on the same side thereof. An electric spiral discharge shaft 10 for pushing electrolyte and impurities into the discharge channel 6 is provided at the bottom of the electrolytic cell 2. The electric spiral discharge shaft 10 includes a central shaft 101, a spiral blade 102 and a motor 103. The central shaft 101 is rotatably connected to the bottom of the electrolytic cell 2, and the left end of the central shaft 101 extends into the discharge channel 6. The central shaft 101 is connected with the spiral blade 102. A motor 103 is installed on the left outer wall of the discharge channel 6. The output shaft of the motor 103 is connected to the central shaft 101 to drive the central shaft 101 to drive the spiral blade 102 to rotate to push the electrolyte and impurities in the electrolytic cell 2 into the discharge channel 6.Each reaction chamber 21 has two groups of scraper plates 11 connected to the lower part. Each group of scraper plates 11 has two scraper plates 11. The two scraper plates 11 in each group are symmetrical up and down with the plugging plate 7 on the same side as the center. The scraper plates 11 are in close contact with the plugging plate 7 on the same side to scrape off the impurities attached to the plugging plate 7. The scraper plates 11 on the lower side are installed tilted downward, and the scraper plates 11 on the upper side are installed tilted upward to ensure that the impurities on the plugging plate 7 are effectively scraped off, and the impurities scraped from the plugging plate 7 can be directed downward to the bottom of the inner side of the electrolytic cell 2.

[0033] When it is necessary to discharge the used electrolyte, the electric slide rails 9 on the front and rear sides are controlled to work to drive the front and rear connecting plates 8 away from each other, thereby driving the front and rear blocking plates 7 to move away from each other and open, and the waste liquid in the reaction chamber 21 is discharged to the inner bottom of the electrolytic cell 2 and discharged outwardly through the discharge channel 6. At the same time, the electric scissor-type lifting frame 5 is controlled to drive the U-shaped scraper 4 to move downward to scrape off impurities adhered to the inner wall of the electrolytic cell 2 and the side wall of the diaphragm 3. When the blocking plate 7 moves open, the impurities adhered to the blocking plate 7 can be scraped off by the scraper plates 11 on the upper and lower sides, and the impurities fall to the inner bottom of the electrolytic cell 2 and are discharged outwardly through the discharge channel 6. When the liquid level is lower than the plugging plate 7, the electric slide rails 9 on the front and rear sides are controlled to work to drive the front and rear connecting plates 8 to approach each other, thereby driving the plugging plates 7 on the front and rear sides to approach each other and close, so as to achieve the blocking of the reaction chamber 21 and the separation of each reaction chamber 21. At the same time, the electric scissor lift 5 is controlled to drive the U-shaped scraper 4 to move up and reset. By opening the plugging plate 7 to discharge impurities and waste liquid, the impurities and waste liquid can be quickly discharged outward, thereby increasing the replacement speed of the electrolyte, achieving effective and rapid replacement of the electrolyte, and enabling the electrolytic cell 2 to be quickly put into use to improve production efficiency. Controlling the rotation of the electric spiral discharge shaft 10 can push impurities and waste liquid to the left into the discharge channel 6, assisting the discharge of impurities and waste liquid, and ensuring the discharge speed of the discharge channel 6 while avoiding impurities blocking the discharge channel 6. Therefore, the device can prevent impurities from blocking the discharge channel to increase the replacement speed of the electrolyte.

[0034] See also Figure 5-Figure 8The electrolytic cell 2 is provided with a crushing mechanism for crushing and refining impurities, the crushing mechanism includes a cutting net Ⅰ121 slidably arranged at the lower part of the electrolytic cell 2, the cutting net Ⅰ121 is located between the diaphragm 3 and the electric spiral discharge shaft 10, the cutting net Ⅰ121 is V-shaped to adapt to the bottom of the electrolytic cell 2 with a medium-low outer height tilt, and a spring 122 is connected between the rear side wall of the cutting net Ⅰ121 and the rear inner wall of the electrolytic cell 2 from left to right. The lower part of the electrolytic cell 2 is rotatably connected to a rotating shaft 123 located inside the cutting net Ⅰ121, and two cams 123 are symmetrically connected to the rotating shaft 123. 4. Two push rods 125 are symmetrically connected to the cutting net I 121, and the shape of the push rod 125 is an inverted U shape. The two cams 124 are respectively located in the two inverted U-shaped push rods 125 and contact the push rods 125. A transmission assembly is provided on the right outer wall of the electrolytic cell 2, and the transmission assembly includes a lifting plate 126 and a spline shaft 127. Two guide rods are symmetrically connected to the lower part of the right outer wall of the electrolytic cell 2. The lifting plate 126 is slidably connected between the two guide rods, and the lifting plate 126 is rotatably connected to the spline shaft 127. The right outer wall of the electrolytic cell 2 is rotatably connected to a lifting plate 126 located below the lifting plate 126. Spline sleeve Ⅰ128, spline sleeve Ⅰ128 is slidably sleeved on the spline shaft 127, and the spline sleeve Ⅰ128 is connected to the central shaft 101 through a bevel gear set Ⅰ129. The right outer wall of the electrolytic cell 2 is rotatably connected with a spline sleeve Ⅱ1210 located above the lifting plate 126, and the spline sleeve Ⅱ1210 is slidably sleeved on the spline shaft 127. The spline sleeve Ⅱ1210 is connected to the rotating shaft 123 through a bevel gear set Ⅱ1211. The bevel gear set consists of two bevel gears, and the two bevel gears are meshed. Two push-pull members are provided on the right side of the frame 1, and the push-pull members include a push-pull member rotatably connected to the right side of the frame 1 The gear shaft 1212 has a connecting rod Ⅰ1213 connected to it, and a connecting rod Ⅱ1214 is hinged on the connecting rod Ⅰ1213. The connecting rod Ⅱ1214 is hinged to the lifting plate 126. The connecting rod Ⅰ1213 and the connecting rod Ⅱ1214 are located outside the frame 1. The right sides of the bottoms of the two connecting plates 8 are connected with racks 1215, and the two racks 1215 are respectively meshed with the gears on the two gear shafts 1212. Three cutting nets Ⅱ14 are evenly spaced along the circumferential direction on the rotating shaft 123. The cutting net Ⅱ14 is located between the two cams 124 and on the inner side of the cutting net Ⅰ121.

[0035] The rotation of the center shaft 101 drives the spline sleeve I128 to rotate through the bevel gear set I129, the rotation of the spline sleeve I128 drives the spline shaft 127 to rotate, the rotation of the spline shaft 127 drives the spline sleeve II1210 to rotate, the rotation of the spline sleeve II1210 drives the rotating shaft 123 to rotate through the bevel gear set II1211, and the rotation of the rotating shaft 123 drives the cam 124 to rotate. When the longer end of the cam 124 rotates to contact the push rod 125, the cam 124 continues to rotate to push the push rod 125 to move the cutting net I 121 backward, and the spring 122 is compressed accordingly. When the longer end of the cam 124 rotates to disengage from the push rod 125, the spring 122 can push the cutting net I 121 to move forward and reset. The reciprocating movement of the cutting net I 121 can crush and refine larger impurities, making it easy for the impurities to be discharged outward by the electric spiral discharge shaft 10, so as to avoid large impurities from being retained in the electrolytic cell 2 and reduce the risk of large impurities accumulating and adhering to the bottom surface of the electrolytic cell 2. The rotation of the rotating shaft 123 drives the cutting net II 14 to rotate to crush and refine larger impurities, so as to assist the cutting net I 121 in crushing and refining larger impurities, thereby improving the efficiency and effect of crushing and refining impurities.

[0036] When the two connecting plates 8 drive the two side blocking plates 7 to move away from each other and open, the two racks 1215 are driven to move away from each other to push the gear shaft 1212 to rotate. The gear shaft 1212 rotates through the connecting rod Ⅰ1213 and the connecting rod Ⅱ1214, pushing the lifting plate 126 with the spline shaft 127 to move downward and disengage from the spline sleeve Ⅱ1210, so that after the blocking plate 7 is opened, the rotating shaft 123 stops driving the cam 124 and the cutting net Ⅱ14 to rotate, and then the cutting net Ⅰ121 stops moving back and forth. In this way, after the blocking plate 7 is opened, the cutting net Ⅰ121 and the cutting net Ⅱ14 will stop crushing and refining the impurities, thereby avoiding the impurities being thrown upward back into the reaction chamber 21, thereby keeping the reaction chamber 21 clean. When the two connecting plates 8 drive the two side blocking plates 7 to approach each other and close, the two racks 1215 are driven to approach each other to push the gear shaft 1212 to reverse. The gear shaft 1212 reverses through the connecting rod Ⅰ1213 and the connecting rod Ⅱ1214, pulling the lifting plate 126 with the spline shaft 127 to move up and insert it back into the spline sleeve Ⅱ1210, so that after the blocking plate 7 is closed, the cutting net Ⅰ121 and the cutting net Ⅱ14 are driven to crush and refine the impurities, which does not affect the subsequent addition of electrolyte to the electrolytic cell 2, nor does it affect the rapid commissioning of the electrolytic cell 2, thereby improving production efficiency.

[0037] See also Figure 1 and Fig. 9The electrolytic cell 2 is provided with a pressurizing mechanism, which includes a nozzle 131 connected to the upper part of the rear side wall of the electrolytic cell 2, the nozzle on the nozzle 131 extends into the electrolytic cell 2, and the nozzle on the nozzle 131 is tilted downward to spray the gas downward into the electrolytic cell 2. A fan 132 is installed on the left outer wall of the electrolytic cell 2, and the fan 132 is connected to the nozzle 131 through a pipeline 133. An open tank cover 134 that can be rotated backward is hinged on the top rear side of the electrolytic cell 2, and a pressure relief valve 15 is installed on the upper right part of the front side wall of the electrolytic cell 2.

[0038] When discharging impurities and used electrolyte, the tank cover 134 is first turned forward and closed, and then the fan 132 is controlled to work to transport the external gas to the nozzle 131 through the pipeline 133. The nozzle 131 then sprays the gas downward into the electrolytic cell 2 to form an internal pressure difference, thereby achieving pressurization to accelerate the discharge of impurities and waste liquid, thereby significantly improving the replacement speed of the electrolyte. When the pressure in the electrolytic cell 2 exceeds the preset safety value, the pressure relief valve 15 will automatically open to allow part of the gas to be discharged, thereby reducing the pressure in the electrolytic cell 2, ensuring that the pressure in the electrolytic cell 2 is within a safe pressure range, and improving safety.

[0039] See also Figure 1 and Fig. 9 Three transparent windows 23 are embedded and installed evenly spaced from left to right on the front side wall of the electrolytic cell 2. The three transparent windows 23 correspond to the three reaction chambers 21 one by one. Scale lines are engraved on the transparent windows 23. Through the transparent windows 23 with scale lines, the operator can monitor the usage of the electrolyte inside the electrolytic cell 2 in real time, so that the electrolyte can be replenished into the electrolytic cell 2 in time.
