An electrolyte filter with easy-to-replace filter element

Abstract

The present invention discloses an electrolyte filter with an easily replaceable filter element, and the present invention relates to the technical field of electrolyte filtration. Since the filter holes on the surface of the inner filter element are easily clogged by impurities after a long period of filtering work, the filter element needs to be frequently cleaned and maintained. Too many fixing parts fix the filter element, which easily makes the filter element replacement and cleaning process cumbersome and reduces work efficiency. Therefore, a screw barrel is connected with a threaded block to compress a pressure plate, so that a limiting ring and a pressure plate squeeze a filter barrel in the middle position, and the position of the filter barrel is fixed and restricted, so that when a worker replaces the filter barrel, he only needs to open the barrel cover, separate the screw barrel from the threaded block, and then take out the filter barrel, so that it is more convenient for the worker to replace the filter element for maintenance.

During the filtration process of the filter barrel, the horizontal flow rate of the electrolyte entering the filter barrel is limited by the impeller to prevent the filtered electrolyte from flowing out of the filter barrel again during the rotation of the filter barrel, thereby reducing the filtration efficiency. At the same time, the impeller is driven to rotate by the impact, and the spiral blades drive the electrolyte inside the filter barrel to be conducted to the separation mechanism, so that the electrolyte inside the filter barrel that has completed filtration can be quickly discharged, thereby increasing the internal space and allowing the electrolyte on the outside to flow inward, thereby improving the filtration efficiency.

[0013] The present invention provides an electrolyte filter with an easily replaceable filter element. It has the following beneficial effects:

[0014] 1. The filter element is easy to replace the electrolyte filter. It is connected with the threaded block through the screw barrel, which presses the pressure plate, so that the limiting ring and the pressure plate squeeze the filter barrel in the middle position, fix and limit the position of the filter barrel, so that when the worker replaces the filter barrel, he only needs to open the barrel cover, separate the screw barrel from the threaded block, and then take out the filter barrel, making it more convenient for the worker to replace the filter element for maintenance.

[0015] 2. The filter element is easy to replace the electrolyte filter. Through the cooperation of the recoil slot and the filter holes, in the process of filtering the electrolyte, the electrolyte passes through the filter holes and enters a larger space, slowing down the flow rate of the electrolyte, and cooperating with the impeller to limit the flow rate of the electrolyte entering the filter barrel. At the same time, in the process of the filter barrel rotating along the center of the barrel body, the electrolyte entering the filter barrel is used to limit the external electrolyte from entering the filter barrel before passing through the centrifugal mechanism, thereby preventing the filter holes of the filter barrel from being blocked by colloidal impurities during the filtration process, resulting in the filter barrel being unable to filter.

[0016] 3. The filter element is easy to replace the electrolyte filter. During the filtering process of the filter barrel, the impeller limits the horizontal flow rate of the electrolyte entering the filter barrel to prevent the filtered electrolyte from flowing out of the filter barrel again during the rotation of the filter barrel, resulting in reduced filtration efficiency. At the same time, the impeller is driven by the impact to drive the electrolyte inside the filter barrel to be transferred to the separation mechanism through the spiral blades, so that the electrolyte inside the filter barrel can be quickly discharged, increasing the internal space, allowing the electrolyte on the outside to flow inward, and improving the filtration efficiency.

[0017] Fourth, the filter element is easy to replace the electrolyte filter. The overflow cover is covered at the bottom through the guide cover, so that the electrolyte entering the separation mechanism is first guided by the guide cover to prevent the electrolyte from directly flowing out from the gap between the overflow cover and the inner cover tube, resulting in unsatisfactory filtering effect. At the same time, the guide cover conducts the electrolyte to the outside, which can better drive the incoming electrolyte to rotate and improve the separation effect of internal metal debris impurities.

[0033] A separation mechanism 4, which is used to separate metal particle impurities in the electrolyte; and the separation mechanism 4 is installed at the bottom of the centrifugal mechanism 3;

[0034] The filter mechanism 2 includes a filter barrel 21, the outer side of the filter barrel 21 is evenly provided with filter holes, and the inner wall of the filter barrel 21 is evenly provided with recoil grooves 27, the position of the recoil grooves 27 corresponds to the filter holes, and the width of the recoil grooves 27 gradually decreases from the inside to the outside, and the top of the filter barrel 21 is fixedly connected with a connecting plate 24, the inner wall of the connecting plate 24 is evenly provided with clamping holes, and a pressure plate 25 is clamped at the clamping hole of the connecting plate 24, and the pressure plate 25 is located at the top of the connecting plate 24. A screw barrel 22 is arranged on the top of the pressure plate 25, and the bottom of the screw barrel 22 is fitted with the top of the pressure plate 25, and the inner wall of the screw barrel 22 is threadedly connected with a threaded block 23. The electrolyte entering the barrel body 11 is filtered through the filter holes on the surface of the filter barrel 21, and large impurities are filtered. At the same time, in the process of filtering the plate, the screw block 23 and the centrifugal mechanism 3 are connected. The connection is made by threading the screw barrel 22 with the threaded block 23 during installation, and the pressure plate 25 is pressed against the connecting plate 24. The pressure plate 25 is clamped and pressed against the connecting plate 24 to limit the position of the filter barrel 21. The bottom of the threaded block 23 is fixedly connected to the centrifugal mechanism 3. A limiting ring 26 is provided at the bottom of the filter barrel 21. The inner wall of the limiting ring 26 fits the outer side of the filter barrel 21. A clamping ring 28 is fixedly connected to the bottom of the limiting ring 26. The inner wall of the clamping ring 28 is clamped with the centrifugal mechanism 3. In the process that the centrifugal mechanism 3 drives the filter barrel 21 to rotate along the center position of the barrel body 11, the electrolyte is driven to rotate and circulate inside the barrel body 11 through the filter barrel 21. At the same time, during the rotation process, the electrolyte enters the interior of the filter barrel 21. The electrolyte after removing large impurities from the electrolyte of the filter barrel 21 passes through the centrifugal mechanism 3 and enters the separation mechanism 4.

[0035] The second embodiment is based on the first embodiment. Figure 6 to Figure 7 As shown, the centrifugal mechanism 3 includes a perforated plate 31, the outer side of the perforated plate 31 is tightly fitted with the inner wall of the barrel body 11, and the top of the perforated plate 31 is evenly provided with circular holes along the center of the circle, and the circular holes of the perforated plate 31 are rotatably installed with a slot cylinder 32, and a connecting shaft 37 is fixedly installed at the bottom center of the perforated plate 31, and the connecting shaft 37 at the bottom of the perforated plate 31 is connected to the output end of the motor 5, and the motor 5 drives the perforated plate 31 to rotate inside the barrel body 11, so that the perforated plate 31 is clamped with the clamping ring 28 through the internal clamping groove cylinder 32, and the filter barrel 21 is driven to rotate along the center of the circle of the barrel body 11, and the bottom end of the connecting shaft 37 is connected to the output end of the motor 5, and a clamping groove is clamped on the top of the outer side of the clamping groove cylinder 32, and the clamping groove cylinder 32 is clamped with the clamping ring 28 through the clamping groove, and a connecting ring 36 is fixedly installed at the bottom of the perforated plate 31, and the connecting ring 36 is evenly installed at the bottom of the perforated plate 31, and the top of the connecting ring 36 fits with the bottom of the clamping groove cylinder 32.

[0036] A swivel seat 33 is rotatably installed at the center position of the inner wall of the connecting ring 36, and a sleeve shaft 35 is fixedly connected to the center position of the top of the swivel seat 33. The top of the sleeve shaft 35 is fixedly connected to the bottom of the threaded block 23, and sleeve grooves are symmetrically provided on the outer side of the sleeve shaft 35. Impellers 34 are rotatably installed at the sleeve grooves of the sleeve shaft 35. Spiral blades are provided on the outer side of the impeller 34. The electrolyte passing through the filter barrel 21 impacts the blades of the impeller 34 on the outer side of the sleeve shaft 35, driving the impeller 34 to rotate. The impeller 34 limits the flow rate of the electrolyte passing through the filter barrel 21, so that it passes through the circular hole of the orifice plate 31 and enters the separation mechanism 4 under the rotation of the impeller 34. The impeller 34 is located inside the filter barrel 21, and there is a gap between the blades of the impeller 34 and the inner wall of the filter barrel 21.

[0037] The third embodiment is based on the first and second embodiments. Figures 8 to 9 As shown, the separation mechanism 4 includes an outer cover tube 41 and an inner cover tube 45. The top of the outer cover tube 41 is fixedly connected to the bottom of the orifice plate 31, the top of the inner cover tube 45 is fixedly connected to the bottom of the orifice plate 31, and the top of the inner cover tube 45 is provided with an empty groove, and the empty grooves of the inner cover tube 45 are fixedly connected with a cushion block 42. The inner cover tube 45 is located on the outside of the connecting shaft 37, and a guide cover 43 is fixedly installed on the top of the outer side of the inner cover tube 45. The electrolyte entering the separation mechanism 4 has been filtered out of large impurities, but there are still fine metal debris inside. The electrolyte passes through the orifice plate 31. After that, it enters the interior of the outer cover tube 41. During the falling process, the electrolyte is guided by the guide cover 43 to fall into the bottom of the inner wall of the outer cover tube 41. The outer cover tube 41 is driven to rotate by the rotating hole plate 31, and the entering electrolyte is driven to rotate together by the rotating outer cover tube 41. The metal debris in the electrolyte is concentrated at the outer bottom edge of the liquid inside the outer cover tube 41 under the action of its own density and centrifugal force. The outer side of the guide cover 43 is tilted downward, and the inner wall of the outer cover tube 41 is fixedly connected with an overflow cover 49, which is located directly below the guide cover 43.

[0038] The outer bottom of the outer cover tube 41 is evenly provided with separation grooves, and the overflow groove on the outer side of the outer cover tube 41 is fixedly connected with a slag collecting groove 44, and the outer side of the outer cover tube 41 is fixedly connected with a slag blocking ring 46, the bottom end of the slag blocking ring 46 is bent outward, and the slag blocking ring 46 is located inside the outer cover tube 41 and the slag collecting groove 44, and the bottom of the inner cover tube 45 is fixedly connected with a groove ring 47, and the bottom of the groove ring 47 is evenly provided with a liquid guide groove, and the edge of the top of the groove ring 47 is fixedly connected to the bottom of the outer cover tube 41, and an anti-overflow cylinder 48 is provided at the bottom of the groove ring 47, and the metal is passed through the separation groove. Debris impurities are introduced into the slag collecting tank 44 for collection. In the process of continuous accumulation of impurities, the slag blocking ring 46 cooperates with the slag collecting tank 44 to limit the metal debris entering the interior from flowing out of the slag collecting tank again. As the electrolyte inside the outer cover tube 41 accumulates, the upper layer of electrolyte without impurities overflows through the gap between the overflow cover 49 and the inner cover tube 45 and falls to the bottom of the barrel body 11. The electrolyte after filtration is discharged through the discharge pipe 7, and the top of the anti-overflow tube 48 fits with the bottom of the groove ring 47, and the bottom of the anti-overflow tube 48 is fixedly connected to the bottom of the inner wall of the barrel body 11.

[0039] During use, workers connect the pipelines with the feed pipe 6 and the discharge pipe 7 respectively, and introduce the electrolyte to be filtered into the filter bin 1 through the feed pipe 6 by a liquid pump. Then the worker starts the motor 5, and the motor 5 drives the centrifugal mechanism 3 to rotate. The centrifugal mechanism 3 drives the filter mechanism 2 and the separation mechanism 4 to rotate at the same time, so that the electrolyte passed through the filter mechanism 2 filters the large impurities in the electrolyte, and the electrolyte after the large impurities are removed passes through the centrifugal mechanism 3 and enters the separation mechanism 4. The centrifugal mechanism 3 drives the separation mechanism 4 to rotate, so that the incoming electrolyte rotates, and the fine metal impurities in the electrolyte are separated by the action of centrifugal force. The electrolyte after the impurities are removed overflows and enters the space between the barrel body 11 and the separation mechanism 4, and is discharged through the discharge pipe 7.

[0040] During the preliminary filtration through the filter mechanism 2, the electrolyte entering the barrel body 11 is filtered through the filter holes on the surface of the filter barrel 21, and large impurities are filtered out. At the same time, during the filtration process, it is connected to the centrifugal mechanism 3 through the threaded block 23. During installation, the screw barrel 22 is threadedly connected to the threaded block 23, and the pressure plate 25 is pressed against the connecting plate 24. The pressure plate 25 and the connecting plate 24 are clamped and pressed to limit the position of the filter barrel 21. At the same time, when the centrifugal mechanism 3 drives the filter barrel 21 to rotate along the center position of the barrel body 11, the electrolyte is driven to rotate and circulate inside the barrel body 11 through the filter barrel 21. At the same time, during the rotation process, the electrolyte enters the interior of the filter barrel 21, and the electrolyte that has passed through the filter barrel 21 to remove large impurities passes through the centrifugal mechanism 3 and enters the separation mechanism 4.

[0041] In the centrifugal mechanism 3, the connecting shaft 37 at the bottom of the orifice plate 31 is connected to the output end of the motor 5, and the motor 5 drives the orifice plate 31 to rotate inside the barrel body 11, so that the orifice plate 31 is clamped with the clamping ring 28 through the internal clamping groove cylinder 32, and drives the filter barrel 21 to rotate along the center position of the barrel body 11. The electrolyte passing through the filter barrel 21 passes through the blades of the impeller 34 on the outside of the impact sleeve shaft 35, driving the impeller 34 to rotate. The flow rate of the electrolyte passing through the filter barrel 21 is limited by the impeller 34, so that it passes through the circular hole of the orifice plate 31 and enters the separation mechanism 4 under the rotation of the impeller 34.

[0042] The electrolyte entering the separation mechanism 4 has been filtered to remove large impurities, but there are still fine metal debris inside. After the electrolyte passes through the perforated plate 31, it enters the interior of the outer cover tube 41. During the falling process, the electrolyte is guided by the guide cover 43 to fall to the bottom of the inner wall of the outer cover tube 41. The rotating perforated plate 31 drives the outer cover tube 41 to rotate, and the rotating outer cover tube 41 drives the entering electrolyte to rotate together. The metal debris in the electrolyte is concentrated under the action of its own density and centrifugal force. At the outer bottom edge of the liquid inside the outer cover tube 41, metal debris impurities are introduced into the slag collecting tank 44 through the separation groove for collection. In the process of continuous accumulation of impurities, the slag blocking ring 46 cooperates with the slag collecting tank 44 to limit the metal debris entering the interior from flowing out of the slag collecting tank again. As the electrolyte inside the outer cover tube 41 accumulates, the upper layer of electrolyte without impurities overflows through the gap between the overflow cover 49 and the inner cover tube 45 and falls on the bottom of the barrel body 11, and the electrolyte after filtration is discharged through the discharge pipe 7.

[0043] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
