Description

Technical Field

[0001] This utility model relates to the technical field of evaporator accessories, specifically a filter component suitable for a high-efficiency and energy-saving battery wastewater treatment evaporator. Background Technology

[0002] The production process of batteries (such as lithium-ion batteries and lead-acid batteries) generates a large amount of wastewater containing heavy metals, acids, alkalis, and organic pollutants. Direct discharge of this wastewater will seriously harm the environment. Evaporation and concentration technology, due to its high efficiency and stability, has become one of the key processes for battery wastewater treatment. The filtration components of the evaporator, as a pretreatment step, directly affect the evaporation efficiency and equipment lifespan.

[0003] Chinese invention patent CN116081883B discloses a wastewater waste heat evaporator and filtration method for wastewater filtration and purification. The evaporator has a filtration mechanism above the evaporation mechanism, and a scraper is used in the filtration mechanism to clean impurities from the surface of the filter cover. The cleaned impurities are then collected in a storage box on one side. However, the effect of mechanical scraping cleaning by scraper alone is limited. It cannot completely remove highly adhesive pollutants, nor can it clean impurities attached to the mesh.

[0004] Therefore, we propose a filter assembly suitable for high-efficiency and energy-saving battery wastewater treatment evaporators to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a filter assembly suitable for a high-efficiency, energy-saving battery wastewater treatment evaporator, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A filter assembly suitable for a high-efficiency energy-saving battery wastewater treatment evaporator includes a tank, a collection assembly, and a spraying assembly. A water guide is provided at the top of the tank, a filter structure is provided inside the tank, a scraping assembly is rotatably provided on the surface of the filter structure, and a drain is provided at the bottom of the tank.

[0008] The collection component is disposed outside the filter structure, and the collection component includes a lifting component with an inclined top surface, and the lifting component is raised and lowered along the vertical direction of the filter structure.

[0009] When the lifting component moves to its highest position, the inclined surface of the lifting component connects with the end of the upper surface of the filter structure.

[0010] The spraying assembly includes a water storage tank and a rotating structure. The rotating structure moves in a circular motion along the bottom wall of the filter structure. Multiple sprayers are installed on the bottom wall of the rotating structure. The water storage tank is installed between the inner walls of the tank body and below the rotating structure. A water supply conduit is also connected between the sprayers and the water storage tank.

[0011] According to the above technical solution, the filter structure includes a filter cover, the upper surface of which is inclined, and the inclined surface of the lifting component can fall on the extended surface of the inclined surface of the filter cover. Several connecting rods are fixedly connected to the upper surface of the filter cover near the edge, and the other end of the connecting rods is fixed to the inner wall of the tank.

[0012] According to the above technical solution, the collection component also includes an "L"-shaped limiting ring seat, a fixing ring seat is provided between the inner walls of the tank, the limiting ring seat is fixed on the fixing ring seat, and the lifting component slides between the filter cover and the vertical side wall opposite to the limiting ring seat.

[0013] Several screws are rotatably installed below the bottom wall of the fixed ring seat, and several connectors are installed on the bottom wall of the lifting component. The connectors are arranged in a "Z" shape, and the screws pass through the connectors and engage with the inner wall through threaded transmission.

[0014] According to the above technical solution, the tank body has multiple discharge ports along its outer circumference, and a sliding cover is slidably installed inside the discharge port. The bottom end of the discharge port and the top surface of the limiting ring seat are on the same horizontal plane.

[0015] According to the above technical solution, the rotating structure includes a rotating ring seat, on which a dovetail-shaped guide ring is provided. The guide ring is rotatably disposed between the vertical inner walls of the filter cover, and multiple gears meshing and driving with it are provided on the outside of the rotating ring seat.

[0016] According to the above technical solution, an annular top cover is rotatably provided between the top inner walls of the water storage tank, one end of the conduit passes through the top cover and extends into the interior of the water storage tank, and multiple connecting parts are connected between the rotating ring seat and the top cover.

[0017] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0018] By setting up a collection component and a spray component, when cleaning impurities from the filter cover, the spray direction of the spray component is adjusted to reverse-flush the impurities attached to the mesh of the filter cover. This allows impurities that are difficult to remove by the scraper to be flushed out of the mesh by the water flow and scraped off by the scraper component above into the collection component on the side. At the same time, the height of the collection component is adjusted so that it can form a uniform slope with the inclined surface of the filter cover, allowing the flushed impurities to flow out of the discharge port more effectively, thus improving the cleaning effect of the filter component.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-7This utility model provides a technical solution: a filter assembly suitable for a high-efficiency energy-saving battery wastewater treatment evaporator, including a tank 1. At least two discharge ports are provided on the circumferential surface of the tank 1. A sliding cover 11 with an arc-shaped structure is slidably arranged between the inner walls of the discharge ports. A lever is fixed on the sliding cover 11, and the end wall of the sliding cover 11 is fixed to the end wall of the discharge port by suction. A connecting ring 12 is also fixedly connected to the circumferential surface of the tank 1 near the bottom. Multiple locking posts are installed on the bottom wall of the connecting ring 12 (with the same structure and function as the locking posts described in announcement number CN116081883B).

[0029] A water guide 2 is fixedly installed between the top inner wall of the tank body 1 and the bottom wall of the water guide 2 by bolts. The water guide 2 has a recessed middle section and two water inlets and a fixing hole on its bottom wall.

[0030] A drainer 13 is fixedly installed between the bottom inner walls of the tank 1 by bolts. The top and bottom surfaces of the drainer 13 are both recessed, and a drain pipe is installed in the middle of the drainer 13.

[0031] A fixing ring seat 14 is also fixedly installed between the inner walls of the tank body 1 by bolts.

[0032] A filter structure is provided in the middle of the interior of the tank body 1. The filter structure includes a filter cover 4. The upper surface of the filter cover 4 is inclined. At least three connecting rods 41 are fixedly connected to the upper surface of the filter cover 4 near the edge. The other end of the connecting rods 41 is fixed to the inner wall of the tank body 1. The upper surface of the filter cover 4 has a mesh structure.

[0033] It should be further explained that after the wastewater enters the tank 1 through the inlet, the impurities and particles in the wastewater are blocked on the surface of the filter cover 4 by the mesh structure of the filter cover 4, while the liquid continues to flow downward and finally flows from the drain pipe into the evaporation mechanism.

[0034] To prevent clogging of the mesh on the filter cover 4, the prior art document further includes the following optimizations and improvements:

[0035] A scraping assembly 3 is installed above the filter cover 4. The scraping assembly 3 includes a gear 31, a transmission component 32, and a scraper 33. The transmission component 32 has a shaft-like structure. The transmission component 32 passes through the fixing hole and rotates between the inner walls of the fixing hole. The transmission component 32 and the fixing hole are height-limited by a limiting ring on the outer surface of the transmission component 32 (the limiting ring is not shown in the figure; that is, the limiting ring is fixed to the transmission component 32 as a whole and rotates between the inner walls of the limiting bearing). The limiting bearing is as follows: Figure 2As shown, it is fixedly installed in the middle of the top surface of the water guide 2. Gear 31 is installed on the top of the transmission component 32 (gear 31 has the same structure and function as the first gear in announcement number CN116081883B). An umbrella-shaped connecting plate is threadedly connected to the bottom of the transmission component 32. At least three scraper rods 33 are evenly fixed on the outer periphery of the connecting plate. The lower surface of the scraper rods 33 is in rotational contact with the inclined surface of the filter cover 4.

[0036] It should be further explained that, through the transmission action of gear 31, the connecting disc is driven to rotate through the transmission component 32, thereby causing the scraper 33 to move in a circular motion along the inclined surface of the filter cover 4. During the motion, the blocked impurity particles are continuously scraped off and fall down along the inclined surface of the filter cover 4.

[0037] Based on the above optimizations and improvements, although the scraper 33 can effectively remove impurity particles, suspended solids and colloids in high-concentration wastewater can easily clog the mesh. Since the scraper 33 cannot make contact with the inside of the mesh, it cannot guarantee smooth flow through the mesh, and over time, clogging will still occur. Therefore, this invention further optimizes and improves the process, specifically as follows:

[0038] A filter assembly suitable for a high-efficiency energy-saving battery wastewater treatment evaporator further includes a collection assembly and a spraying assembly. The collection assembly is located outside the filter structure, and the spraying assembly is located below the filter structure.

[0039] The collection assembly includes a lifting component 6 and a limiting ring seat 5. The limiting ring seat 5 is arranged in an "L" shape. The top of the limiting ring seat 5 is fixed to the top surface of the fixing ring seat 14 by bolts. The lifting component 6 is arranged in a ring shape. The top surface of the lifting component 6 is inclined. The lifting component 6 slides between the vertical sidewalls opposite to the filter cover 4 and the limiting ring seat 5. At least three baffles 61 are fixed to the inclined edge of the lifting component 6 by screws. The baffles 61 are arranged vertically.

[0040] The limiting ring seat 5 has multiple vertical holes 1 along its height direction, and the fixing ring seat 14 has multiple vertical holes 2 along its height direction. The vertical holes 1 and 2 correspond one-to-one and are all set in the same number as the baffles 61. A rotary motor 1 is installed between the inner walls of the fixing ring seat 14. A detachable screw is installed on the output end of the rotary motor 1. The bottom end of the screw is set in a "⊥" shape.

[0041] Multiple card seats 62 are fixedly installed on the bottom wall of the lifting component 6 by screws. A "Z"-shaped connector 63 is inserted and fixed inside the card seat 62 (the connector 63 is set in equal numbers to the baffle 61). One end of the screw passes through the connector 63 and engages with it in threaded transmission. The end of the connector 63 connected to the card seat 62 slides between the inner walls of the vertical hole 1 and the vertical hole 2.

[0042] In addition, at least three supports 51 are fixedly installed on the inner surface of the limiting ring seat 5 by bolts. A second rotary motor is installed on the bottom wall of the support 51, and a second gear 511 is rotatably arranged on the top surface of the support 51. The output shaft of the second rotary motor is connected to the second gear 511 for drive.

[0043] It should be further explained that by starting the rotary motor, the screw is driven to rotate, and under the action of threaded transmission, the connecting part 63 can drive the lifting part 6 to move up and down synchronously. When the connecting part 63 contacts the bottom end of the vertical hole 1 on the limiting ring seat 5, the lifting part 6 is at its lowest position. The baffle 61 blocks one side of the opening of the vertical hole 2, thus forming a recessed annular space between the filter cover 4, the limiting ring seat 5 and the lifting part 6. When the connecting part 6 contacts the top end of the vertical hole 1, the lifting part 6 is at its highest position. At this time, the highest point of the inclined surface of the lifting part 6 moves to the end of the inclined surface of the filter cover 4, and the inclined surface falls on the extension direction of the inclined surface. The lowest point of the inclined surface of the lifting part 6 falls on the plane of the top surface of the limiting ring seat 5 and contacts the edge of the top surface of the limiting ring seat 5. At this time, the filter cover 4 can be cleaned and drained by opening the sliding cover 11.

[0044] The spray assembly includes a rotating ring seat 7, a fixed box 73, and a sprayer 731. An integral guide ring (with a dovetail cross-section) is fixed on the rotating ring seat 7. The guide ring is rotatably disposed between the vertical inner walls of the filter cover 4. The outer circumferential surface of the rotating ring seat 7 is evenly provided with tooth grooves, and multiple gears 511 mesh with the tooth grooves for transmission.

[0045] At least three card holders 71 are fixedly installed on the bottom wall of the rotating ring seat 7 by screws. The fixing box 73 is fixed between the inner walls of the card holders 71 by screws. A groove is provided at one end of the fixing box 73. A miniature water pump (not shown in the figure) that is connected to the conduit 732 and the hose is installed in the fixing box 73. The sprayer 731 is rotatably mounted between the inner walls of the groove by a shaft connection. A waterproof shell is installed on the outer wall of the fixing box 73 by screws. A rotary motor 3 (not shown in the figure) that drives the sprayer 731 by shaft is installed in the waterproof shell. A hose is connected between one end of the fixing box 73 and the end of the sprayer 731. A rigid conduit 732 is connected to the other end of the fixing box 73.

[0046] A water storage tank 8 is fixed to the inner wall of the tank body 1 by bolts. A water inlet is also provided on the tank body 1 below the discharge port. The water inlet is connected to the water storage tank 8. A water inlet valve is connected to the outer end of the water inlet. Water can be injected into the water storage tank 8 by connecting a water pipe to the water inlet valve. The water storage tank 8 is located below the rotating ring seat 7. A ring-shaped top cover is also rotatably installed between the inner wall of the top of the water storage tank 8. The top cover has a number of guide holes equal to the number of guide tubes 732. One end of the guide tube 732 passes through the guide hole and extends into the interior of the water storage tank 8. The guide tube 732 is fixed to the top cover as a whole. At least three connecting parts 72 are fixed between the rotating ring seat 7 and the top cover by screws. The connecting parts 72 are "L"-shaped plate structures.

[0047] It should be further explained that when cleaning the filter cover 4, the rotating motor 3 is started, causing the sprayer 731 to adjust its angle to face the filter cover 4. Then, the rotating motor 3 is stopped, and the water pump is started, causing the water in the water tank 8 to flow and spray out along the conduit 732 to the sprayer 731. This causes impurities and other debris attached to the mesh of the filter cover 4 to be subjected to an upward water impact force. At the same time, with the circular motion of the scraper 33, the impurities and other debris flushed upward are scraped off by the scraper 33 onto the lifting member 6 located at the highest position. Finally, the impurities and some water are discharged along the limit. The top surface of the ring seat 5 flows out from the discharge port, while the remaining water that can fall is discharged from the discharge pipe. At the same time, during the cleaning process, the second rotating motor is started, which causes the second gear 511 to rotate, thereby driving the rotating ring seat 7 to rotate synchronously, so as to ensure that the mesh of the filter cover 4 can be washed. Due to the setting of the second connecting piece 72, the top cover on the water storage tank 8 rotates and adjusts synchronously between the inner walls of the water storage tank 8 with the circumferential movement of the guide tube 732. After cleaning is completed, the second rotating motor and the third rotating motor are stopped, and the lifting piece 6 is restored to the lowest position. The sliding cover 11 closes the discharge port.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
