Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic cells, in particular to an electrolytic cell with acid circulation. Background Art

[0002] The electrolytic cell is one of the important equipments that are indispensable to the development of modern industry. When metal is electrolyzed by adding acid into the electrolytic cell, impurities will be generated in the electrolyte. In order to ensure the electrolysis effect of the electrolyte on the metal, the impurities in the electrolyte need to be cleaned to ensure the electrolysis effect of the electrolyte while making the electrolyte recyclable.

[0003] After searching, the Chinese patent "An Electrolyte Circulation Device for an Electrolytic Cell" with the authorization announcement number "CN220685274U" opens the valve on the drain pipe to allow the electrolyte in the cell body to enter the collection tank, and filters the impurities in the electrolyte through the filter in the collection tank to prevent the impurities and the electrolyte from being mixed together. In addition, the filter can be removed from the collection tank by lifting the handles on both sides of the top surface of the filter to disassemble and clean the filter to prevent impurities from accumulating on the filter and clogging the filter.

[0004] In the above application, a filter is used to filter impurities in the electrolyte, and the filter can be cleaned regularly. However, when the impurities retained on the filter gradually increase during the circulation of the electrolyte, the above solution cannot clean the impurities in time. The impurities retained on the filter will cause the fluidity of the electrolyte to decrease when passing through the filter, thereby affecting the circulation effect of the electrolyte.

[0005] Based on this, the utility model designs an electrolytic cell with acid circulation to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides an electrolytic cell with acid circulation.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] An acid liquid circulation electrolytic cell comprises a cell body, a water pump is installed on one side of the cell body, and a water outlet pipe of the water pump is connected to the cell body;

[0009] The filtering mechanism includes a filter box connected to the water inlet pipe of the water pump, a connecting pipe is connected to the upper end of the surface of the filter box and one side of the trough body, a circular ring is rotatably connected to the inner wall of the filter box, and a plurality of evenly distributed filter screens are fixedly connected to the inner wall of the circular ring. The middle part of the filter screen has a "^"-shaped protrusion, and a fixing rod is fixedly connected between the opposite sides of two adjacent filter screens, and a groove is provided at the top of the fixing rod.

[0010] Furthermore, a collection frame is fixedly connected to the bottom end of the bottom end of the ring, through holes are provided at both ends of the inner wall of the fixing rod, and the top of the collection frame is provided with feed ports with the same number as the through holes, and the through holes are connected to the grooves and the corresponding feed ports.

[0011] Furthermore, a servo motor is fixedly connected to the surface of the filter box, and one end of the circular rotating shaft passes through the filter box and is fixedly connected to the output shaft of the servo motor.

[0012] Furthermore, the overall shape of the filter box is spherical, the surface of the ring fits with the inner wall of the filter box, and the center of the ring coincides with the center of the filter box.

[0013] Furthermore, a plurality of evenly distributed first circular holes are formed at the bottom end of the fixing rod, and the diameter of the first circular holes is the same as the mesh diameter of the filter screen.

[0014] Furthermore, a guide ring is fixedly connected to the inner wall of the collection frame, and an angle is formed between the surface of the guide ring and the vertical plane.

[0016] Furthermore, both sides of the inner wall of the groove are inclined. Beneficial effects

[0017] 1. The above-mentioned filtering mechanism utilizes multiple filter screens to filter impurities in the electrolyte. Under the action of the filter screen slope and groove, the electrolyte flows downward while the impurities retained on the filter screen slope slide into the groove, thereby gathering the impurities intercepted by the filter screen and preventing the impurities from being retained on the filter screen.

DETAILED DESCRIPTION

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] In some embodiments, please refer to the appendix of the specification. Figure 1-5An electrolytic cell with acid circulation includes a cell body 100, a water pump 200 is installed on one side of the cell body 100, and a water outlet pipe of the water pump 200 is connected to the cell body 100.

[0030] In an embodiment of the present invention, the water inlet pipe of the water pump 200 is connected to the upper end of one side of the tank body 100, and when the metal is electrolyzed, the level of the electrolyte in the tank body 100 is lower than the level of the connection between the water inlet pipe of the water pump 200 and the tank body 100.

[0031] The filtering mechanism 300 includes a filter box 310 connected to the water inlet pipe of the water pump 200. The upper end of the surface of the filter box 310 is connected to one side of the tank body 100 by a connecting pipe 320. The inner wall of the filter box 310 is rotatably connected to a ring 330. The inner wall of the ring 330 is fixedly connected to a plurality of evenly distributed filter screens 340. The middle part of the filter screen 340 is raised in a "^" shape. A fixing rod 350 is fixedly connected between the opposite sides of two adjacent filter screens 340, and a groove 351 is provided at the top of the fixing rod 350.

[0032] In an embodiment of the present invention, when acid is added to the tank body 100 to electrolyze the metal, the water pump 200 is started by the controller, so that the water inlet pipe of the water pump 200 generates suction. At this time, the electrolyte in the tank body 100 enters the filter box 310 through the connecting pipe 320 and is filtered through multiple filter screens 340. The electrolyte filtered by the filter screens 340 enters the water inlet pipe of the water pump 200 and is transported back to the tank body 100 under the action of the water pump 200, thereby realizing circulation. A fixing plate is fixedly connected between the surface of the filter box 310 and one side of the tank body 100. During the filtration process of the multiple filter screens 340, impurities are intercepted by the filter screens 340 and retained on the inclined surfaces of the filter screens 340. At the same time, as the water flow continues to flow downward from the connecting pipe 320, the impurities retained on the filter screens 340 will slide down into the grooves 351 on both sides of the filter screens 340 under the action of its inclined surface, thereby preventing impurities from being retained on the filter screens 340.

[0033] A through groove is provided on the surface of the filter box 310, and a sealing plate matching the through groove is provided. When the device is operating normally, the sealing plate is installed with the filter box 310 by bolts to seal the through groove. When the sealing plate and the filter box 310 are installed, the inner surface of the sealing plate and the inner surface of the filter box 310 are on the same arc surface. When the filter screen 340 is cleaned regularly, the sealing plate can be opened to clean the filter box 310.

[0034] In some embodiments, as Figure 2 、 Figure 3 and Figure 5As shown, as a preferred embodiment of the present invention, the bottom end of the ring 330 is fixedly connected to a collection frame 370, both ends of the inner wall of the fixing rod 350 are provided with through holes 352, and the top of the collection frame 370 is provided with feed ports 371 with the same number as the through holes 352, and the through holes 352 are connected to the grooves 351 and the corresponding feed ports 371.

[0035] In an embodiment of the present invention, the overall shape of the collection frame 370 is annular, and the outer edge diameter of the collection frame 370 is smaller than the outer edge diameter of the ring 330. The position of the feed port 371 corresponds one-to-one to the position of the through hole 352. During the filtering process of the electrolyte, when impurities slide into the groove 351, when the impurities in the groove 351 flow to the top of the through hole 352, the impurities will pass through the through hole 352 and the feed port 371 and fall into the collection frame 370, thereby completing the collection of impurities and reducing the impurities in the groove 351.

[0036] In some embodiments, as Figure 2 and Figure 3 As shown, as a preferred embodiment of the present invention, a servo motor 360 is fixedly connected to the surface of the filter box 310 , and one end of the rotating shaft of the ring 330 passes through the filter box 310 and is fixedly connected to the output shaft of the servo motor 360 .

[0037] In an embodiment of the present invention, when the electrolyte is circulated and filtered, the servo motor 360 is started by the controller to drive the ring 330 to rotate, so that the ring 330 rotates clockwise at an angle of fifteen degrees and counterclockwise at an angle of fifteen degrees, and the ring 330 rotates back and forth between fifteen degrees clockwise and fifteen degrees counterclockwise. The reciprocating rotation effect is best within the set angle, and the specific reciprocating rotation angle can be set according to actual conditions.

[0038] During the reciprocating rotation of the ring 330 , the fluidity of impurities on the filter 340 will be increased. At the same time, the impurities in the multiple grooves 351 will flow better toward the through holes 352 under the action of rotation, so that the impurities in the grooves 351 can better enter the collection frame 370 .

[0039] In some embodiments, as Figure 2 As shown, as a preferred embodiment of the present invention, the overall shape of the filter box 310 is spherical, the surface of the ring 330 fits the inner wall of the filter box 310, and the center of the ring 330 coincides with the center of the filter box 310.

[0040] In the embodiment of the present invention, when the servo motor 360 drives the ring 330 to rotate back and forth, the surface of the ring 330 always fits into the inner wall of the filter box 310, thereby avoiding the generation of a gap between the surface of the ring 330 and the inner wall of the filter box 310 during the rotation process, thereby ensuring the filtering effect of the electrolyte.

[0041] In some embodiments, as Figure 4 As shown in FIG. 3 , as a preferred embodiment of the present invention, a plurality of evenly distributed first circular holes 353 are formed at the bottom end of the fixing rod 350 , and the diameter of the first circular holes 353 is the same as the mesh diameter of the filter screen 340 .

[0042] In the embodiment of the present invention, during the filtration of the electrolyte, when the electrolyte enters the groove 351 , impurities are retained in the groove 351 , and the electrolyte flows out from the first circular hole 353 , preventing the impurities in the groove 351 from overflowing.

[0043] In some embodiments, as Figure 3 and Figure 5 As shown, as a preferred embodiment of the present invention, a guide ring 372 is fixedly connected to the inner wall of the collecting frame 370, and an angle is formed between the surface of the guide ring 372 and the vertical plane.

[0044] In an embodiment of the present invention, an angle is formed between the inner surface of the guide ring 372 and the inner bottom wall of the collection frame 370. When the circular ring 330 drives the collection frame 370 to rotate back and forth, the guide ring 372 will intercept the impurities in the collection frame 370, ensuring the stability of the impurities retained in the collection frame 370.

[0045] In some embodiments, as Figure 3 and Figure 5 As shown, as a preferred embodiment of the present invention, a plurality of evenly distributed second circular holes 373 are opened at the bottom end of the collecting frame 370 , and the diameter of the second circular holes 373 is smaller than the diameter of the first circular holes 353 .

[0046] In the embodiment of the present invention, when the electrolyte enters the collection frame 370 , the electrolyte will be discharged from the second circular hole 373 , thereby preventing impurities from overflowing from the collection frame 370 .

[0047] In some embodiments, as Figure 4 As shown in FIG. 1 , as a preferred embodiment of the present invention, both sides of the inner wall of the groove 351 are inclined.

[0048] In the embodiment of the present invention, the width between the two sides of the inner wall of the groove 351 gradually narrows from top to bottom, which is conducive to allowing debris on the filter screen 340 to better enter the groove 351.

[0049] It should be noted that the servo motor 360, water pump 200, etc. described above are all devices with relatively mature applications in existing technologies. The specific models can be selected according to actual needs. At the same time, the servo motor 360 and water pump 200 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
