Description

Technical Field

[0001] This utility model relates to the field of electrolyte collection technology, specifically to an electrolyte collection device. Background Technology

[0002] Filtration is essential for electrolytes recovered from or regenerated from old batteries. Therefore, electrolyte collection devices are equipped with filters for filtration.

[0003] After prolonged use, the filter screen needs to be cleaned. There are two cleaning methods: disassembly and online cleaning. Online cleaning is more convenient than disassembly.

[0004] Online cleaning methods include soaking and rinsing or backflushing. Because some electrolytes are volatile and should not be mixed with other liquids, there are higher requirements for sealing during online cleaning.

[0005] This solution proposes an electrolyte collection device that can maintain a high degree of sealing while achieving online filter cleaning, and the sealing action and cleaning action are mechanically linked to improve the ease of operation. Utility Model Content

[0006] (I) Technical Issues

[0007] The present invention aims to at least solve the problem in the prior art that the online electrolyte filtration mechanism and the sealing mechanism require a high degree of coordination.

[0008] (II) Technical Content

[0009] This solution provides an electrolyte collection device, achieved through the following specific technical means, including:

[0010] Collection box, used to store the collected electrolyte;

[0011] The outer cylinder is fixedly installed at the top opening of the collection box, with flow holes distributed at its bottom and a feed inlet at the top.

[0012] The filter screen is located in the outer cylinder. A set of downward-extending arc-shaped extension plates are connected to both sides of the filter screen. A lower window is formed between the bottom ends of the two sets of arc-shaped extension plates. At the same time, the arc-shaped extension plates slide against the inner wall of the outer cylinder.

[0013] A hole sealer is provided in each set of downstream holes to intermittently block the downstream holes. When the hole sealer is located in the lower window, it is in the open state, and the filter screen is located above the lower window and directly facing the feed inlet. After filtration is completed or when the filter screen needs to be cleaned, the filter screen can be rotated so that a set of arc-shaped extension plates block the downstream holes. At the same time, the set of arc-shaped extension plates push the hole sealer back into the downstream holes to perform a secondary blockage of the downstream holes.

[0014] Preferred technical solution 1: A side window is provided on the side of the outer cylinder, and an air inlet is provided on the opposite side of the outer cylinder;

[0015] An airflow cleaning device is installed on one side of the collection box. The air outlet pipe of the airflow cleaning device is connected to the air inlet, and is used to blow high-pressure airflow into the outer cylinder when necessary to achieve back-blowing cleaning of the filter screen.

[0016] Preferred technical solution 2: Circular baffles are fixed at the front and rear ends of the two sets of arc-shaped extension plates and filter screens, which can rotate in the outer cylinder;

[0017] A convex shaft is fixed at the center of a set of circular baffles. The convex shaft rotates through the end wall of the outer cylinder and is fixedly connected to the shaft end of a set of motors fixed on the end wall of the outer cylinder.

[0018] Preferred technical solution 3: The orifice sealer includes a tapered tube fixed in the downflow orifice, with the wide end of the tapered tube facing upwards. A set of sealing balls is located inside the tapered tube. A spring connects the bottom of the sealing balls to the lower part of the tapered tube. When the lower window moves directly downwards, the top of the sealing balls extends out of the downflow orifice. At this time, a gap is left between the sealing balls and the tapered tube wall for the electrolyte to flow through.

[0019] Preferred technical solution four: A sleeve shaft is fixed through the center of another set of circular baffles, and the sleeve shaft rotates through the other end wall of the outer cylinder;

[0020] A set of crossbars is slidably inserted into the sleeve shaft, and a set of scrapers is fixed to the inner end of the crossbars. When the crossbars are pulled out, the scrapers scrape against the inner walls of the two sets of arc-shaped extension plates and the inner wall of the filter screen to clean the electrolyte, thus avoiding a large amount of electrolyte adhering to the inner wall.

[0021] (III) Technical Effects

[0022] The above structure gives this solution the following advantages:

[0023] 1. By utilizing structural design, the linkage between the filter screen washing state and the outlet sealing state is realized;

[0024] 2. The use of an arc-shaped extension plate and a hole sealer provides double-layer sealing protection for the downstream orifice, effectively preventing the electrolyte in the collection tank from evaporating or other components from entering;

[0025] 3. Online cleaning of the filter screen is achieved by using backflushing.

[0026] 4. After filtration, a scraper can be used to clean the electrolyte adhering to the filter screen and the inner wall of the arc-shaped extension plate. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0035] Example 1

[0036] Please see Figures 1-5 An electrolyte collection device includes a collection tank 1, an outer cylinder 2, a filter screen 3, and a hole sealer 6. The collection tank 1 is used to temporarily store the collected electrolyte. A level gauge 11 is installed on the collection tank 1 to detect the liquid level in the collection tank 1. At the bottom of the collection tank 1, there is a discharge pipe 12 for discharging the electrolyte when needed. Meanwhile, the outer cylinder 2 is fixedly installed at the top opening of the collection tank 1. Downflow holes 21 are distributed at the bottom of the outer cylinder 2, and a feed inlet 22 is opened at the top of the outer cylinder 2 directly opposite the downflow holes 21.

[0037] The filter screen 3 is located in the outer cylinder 2. The filter screen 3 is recessed towards the center of the outer cylinder 2 to increase the collection effect of the electrolyte. A set of downward-extending arc-shaped extension plates 4 can be detachably fixed to both the left and right sides of the filter screen 3. A gap is left between the bottom ends of the two sets of arc-shaped extension plates 4, which is used as the lower window 41. At the same time, the arc-shaped surface of the arc-shaped extension plate 4 is in contact with the circular inner wall of the outer cylinder 2 and rotates and slides. When it is necessary to filter the electrolyte, the filter screen 3 is rotated to the feed port 22. At this time, the downstream hole 21 is located in the lower window 41. After filtration, the filter screen 3 is rotated so that the lower window 41 is away from the downstream hole 21, so that the set of arc-shaped extension plates 4 can block and seal the downstream hole 21.

[0038] The orifice sealer 6 is installed in each group of downflow orifices 21 to intermittently block the downflow orifices 21. When the lower window 41 is directly below, the orifice sealer 6 is in the open state, and the downflow orifices 21 can be used normally. At the same time, the filter screen 3 is located directly above the lower window 41 and directly opposite the feed inlet 22. At this time, the collected electrolyte can be introduced into the feed inlet 22, filtered by the filter screen 3, and then flow into the collection box 1 through the open downflow orifice 21.

[0039] After filtration is completed or when the filter screen 3 needs to be cleaned, the filter screen 3 can be rotated so that the lower window 41 is away from the lower flow hole 21. During the rotation, a set of arc-shaped extension plates 4 that slide over the lower flow hole 21 block the lower flow hole 21. At the same time, the arc-shaped extension plates 4 push the hole sealer 6 back into the lower flow hole 21 to perform a secondary sealing of the lower flow hole 21, effectively preventing the electrolyte in the collection box 1 from evaporating, or the liquid or gas used for cleaning the filter screen 3 from the outside from entering the collection box 1.

[0040] The orifice sealer 6 includes a tapered tube 61 fixed in the downflow orifice 21. The larger opening of the tapered tube 61 faces upward and the smaller opening faces downward. Inside the tapered tube 61, there is a set of sealing balls 62. A spring 63 connects the bottom of the sealing balls 62 to the lower wall of the tapered tube 61. The diameter of the sealing balls 62 is larger than the diameter of the smaller opening of the tapered tube 61 but smaller than the diameter of the larger opening. When the lower window 41 moves directly downward, the arc-shaped extension plate 4 is in a state away from the sealing balls 62. At this time, the top of the sealing balls 62 moves upward and extends out of the downflow orifice 21 under the push of the spring 63. At this time, there is a gap between the sealing balls 62 and the wall of the tapered tube 61 for the electrolyte to flow through. The pushing force of the spring 63 on the sealing balls 62 is greater than the pressure of the electrolyte in the outer cylinder 2 on the sealing balls 62, so that the sealing balls 63 will not be easily pushed into the tapered tube 62 by the electrolyte, thereby ensuring that the electrolyte can smoothly pass through the tapered tube 61 into the collection box 1 during filtration.

[0041] After filtration, as the filter screen 3 rotates, the arc-shaped extension plate 4 rotates and approaches the downstream hole 21. The side of the arc-shaped extension plate 4 pushes the top of the sealing ball 62, causing the sealing ball 62 to move down into the middle and lower part of the conical tube 61 and press against the inner wall of the conical tube 61 to form a seal. To improve the sealing effect, an elastic layer can be wrapped around the outer wall of the middle and lower part of the sealing ball 62 or the inner wall of the conical tube 61. The setting of the elastic layer can further increase the sealing effect.

[0042] Example 2

[0043] Based on Example 1, please refer to Figures 1-5 ;

[0044] The electrolyte collection device has a side window 23 on the side of the outer cylinder 2, and an air inlet 24 on the other side of the outer cylinder 2.

[0045] When rinsing is required, the filter screen 3 should be rotated to face the side window 23. At the same time, the lower window 41 should be rotated to face the air inlet 24. An airflow rinsing device 7 is installed on one side of the collection box 1. The air outlet pipe 71 of the airflow rinsing device 7 is connected to the air inlet 24. It is used to blow high-pressure airflow into the outer cylinder 2 when necessary to achieve back-flushing cleaning of the filter screen 3. The impurities washed away are directly discharged from the side window 23. Before rinsing, a net bag or net cover can be placed on the outside of the side window 23 to collect the impurities.

[0046] The airflow cleaning device 7 is preferably a commercially available high-pressure air supply device with air pressure intensity adjustment function, so that the air pressure can be adjusted as needed to provide sufficient back-flushing cleaning effect;

[0047] Circular baffles 5 are fixed at the front and rear ends of the two sets of arc-shaped extension plates 4 and filter screens 3. They can rotate in the outer cylinder 2 to provide end support for the arc-shaped extension plates 4 and filter screens 3. A convex shaft 51 is fixed at the center of a set of circular baffles 5. The convex shaft 51 rotates through the end wall of the outer cylinder 2 and is fixed to the shaft end of a set of motors 10 fixed on the end wall of the outer cylinder 2. The motors 10 are started to drive the arc-shaped extension plates 4 and filter screens 3 to reciprocate in the outer cylinder 2, realizing the switching of the filter screens 3 between the filtration position and the blowing position.

[0048] Example 3

[0049] Based on Example 2, please refer to Figures 2-3 ;

[0050] The electrolyte collection device has a sleeve shaft 52 fixed through the center of another set of circular baffles 5, and the sleeve shaft 52 rotates through the other end wall of the outer cylinder 2.

[0051] A set of crossbars 8 are slidably inserted into the sleeve shaft 52, and a set of scrapers 9 are fixed to the inner end of the crossbars 8. After each filtration, the crossbars 8 are pulled to drive the scrapers 9 to scrape against the inner walls of the two sets of arc-shaped extension plates 4 and the inner wall of the filter screen 3 to clean the electrolyte, so as to avoid a large amount of electrolyte adhering to the inner wall. When the scrapers 9 scrape, they do not come into contact with the upward-moving sealing ball 62, so they will not affect the opening state of the orifice sealer 6. Therefore, the electrolyte hanging down can flow smoothly into the collection box 1 along the conical tube 61.

[0052] It is worth noting that the motor 10, airflow purging device 7, level gauge 11, and their matching power supply and control switch mentioned in this embodiment can also be provided by the manufacturer. The circuits, electronic components and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and there is no need to elaborate.

[0053] The parts not disclosed in this utility model are all prior art, and their specific structures and working principles will not be described in detail.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
