Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a filtration device for the production of daily chemical products. Background Technology

[0002] In the production of daily chemical products, the mixing and reaction of various raw materials are generally involved. This process may generate solid particles or insoluble impurities. Before bottling or loading into finished product storage tanks, the solution needs to be filtered. The primary function of a filter is to remove impurities that may be generated during production. These impurities are typically intercepted physically to ensure the purity and stability of the product. Through filtration, the components in the solution become more uniform and refined, directly improving the final product quality. Filtering out impurities not only improves product quality but also prevents them from entering subsequent production equipment, causing wear or blockages. This helps maintain stable production line operation and extends equipment lifespan. While existing filtration devices have backwashing structures and drain valves, eliminating the need for disassembly for filter element cleaning, backwashing with clean water is generally required during cleaning, which can interrupt the filtration process. Utility Model Content

[0003] The purpose of this invention is to provide a filtration device for the production of daily chemical products, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A filtration device for the production of daily chemical products, comprising:

[0006] A filter tank has a detachable cover at the top for discharging filtered liquid. The bottom of the filter tank has a receiving cavity for collecting impurities. An inlet is fixedly connected to the outer wall of the bottom of the filter tank. A drain pipe is fixedly connected to the bottom of the receiving cavity, and a solenoid valve is installed on the drain pipe.

[0007] Mounting brackets are used to support and install the filter tank;

[0008] A filter screen cartridge is installed inside a filter tank and is used to filter liquids.

[0009] A cleaning mechanism is installed inside the filter tank. The cleaning mechanism includes a suction ring and a lifting drive module. The lifting drive module is used to drive the suction ring to move up and down. The suction ring is located between the filter screen cylinder and the inner wall of the filter tank. The cleaning mechanism is used to draw liquid from the inside of the filter screen cylinder to the outside.

[0010] Furthermore, two through pipes are provided below the suction ring. The top end of the through pipe is fixedly connected to the suction ring. A one-way valve is installed inside the top end of the through pipe. A sleeve is slidably sleeved at the bottom end of the through pipe. The sleeve is installed and fixedly fixed to the inner wall of the filter tank. A discharge pipe is fixedly connected to the bottom end of the sleeve. A one-way valve is installed inside the bottom end of the discharge pipe.

[0011] Furthermore, the bottom end of the filter tank is provided with a conical part, the bottom end of the conical part is fixedly connected to the receiving cavity, and a neck opening is provided between the conical part and the receiving cavity.

[0012] Furthermore, the bottom end of the outlet tube is offset to one side, and the liquid inlet direction is tangent to the inner wall of the filter tank.

[0013] Furthermore, the lifting drive module includes a hydraulic rod, which is fixedly installed on the filter tank. The output end of the hydraulic rod is fixedly connected to a ring seat.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By setting up the suction ring, when the lifting drive module moves the suction ring upward, a negative pressure is formed inside the suction ring, which causes the liquid to flow from the inside to the outside along the filter screen cylinder covered by the suction ring. This achieves backwashing of the filter screen cylinder covered by the suction ring. The liquid inside the suction ring is guided to concentrate at the bottom of the filter tank, causing impurities to be concentrated in the receiving cavity. When the suction ring moves up and down, it sweeps the entire outer area of ​​the filter screen cylinder, thus achieving real-time cleaning of the filter screen cylinder. The solenoid valve is opened periodically to discharge impurities from the drain pipe, eliminating or reducing the number of times the machine needs to be stopped for cleaning, which is convenient for long-term continuous operation.

Detailed Implementation

[0025] 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.

[0026] Please see Figures 1-5In this embodiment of the present invention, a filtration device for the production of daily chemical products includes a filter tank 200, a mounting frame 100, a filter cylinder 300, and a cleaning mechanism 400. A cover 290 is detachably mounted on the top of the filter tank 200 for discharging the filtered liquid. A receiving cavity 230 is provided at the bottom of the filter tank 200 for collecting impurities. An inlet 250 is fixedly connected to the outer wall of the bottom of the filter tank 200. A drain pipe 231 is fixedly connected to the bottom of the receiving cavity 230, and an electric discharge device is installed on the drain pipe 231. A solenoid valve 240 and a mounting bracket 100 are used to support and install the filter tank 200. A filter screen cylinder 300 is installed inside the filter tank 200 and is used to filter liquid. A cleaning mechanism 400 is installed inside the filter tank 200. The cleaning mechanism 400 includes a suction ring 410 and a lifting drive module 440. The lifting drive module 440 is used to drive the suction ring 410 to move up and down. The suction ring 410 is located between the filter screen cylinder 300 and the inner wall of the filter tank 200. The cleaning mechanism 400 is used to draw liquid from the inside of the filter screen cylinder 300 to the outside.

[0027] Specifically, after the liquid enters the filter tank 200 through the inlet 250, it flows from the outside to the inside of the filter cylinder 300, allowing the filter cylinder 300 to filter the liquid. Impurities are mainly retained on the outside of the filter cylinder 300. With the suction ring 410 in place, when the lifting drive module 440 moves the suction ring 410 upward, a negative pressure is formed inside the suction ring 410. This causes the liquid to flow from the inside to the outside along the part of the filter cylinder 300 covered by the suction ring 410, thereby achieving backwashing of the part of the filter cylinder 300 covered by the suction ring 410. The liquid inside the suction ring 410 is guided to concentrate at the bottom of the filter tank 200, causing impurities to concentrate in the receiving cavity 230. The solenoid valve 240 is opened periodically to discharge the impurities from the drain pipe 231, eliminating or reducing the number of times the machine needs to be stopped for cleaning, which is convenient for long-term continuous operation.

[0028] Example 1

[0029] like Figures 3-6As shown, in this embodiment, two through pipes 420 are provided below the suction ring 410. The top end of the through pipe 420 is fixedly connected to the suction ring 410. A one-way valve 421 is installed inside the top end of the through pipe 420. A sleeve 430 is slidably sleeved on the bottom end of the through pipe 420. The sleeve 430 is installed and fixed on the inner wall of the filter tank 200. An outlet pipe 431 is fixedly connected to the bottom end of the sleeve 430. A one-way valve 432 is installed inside the bottom end of the outlet pipe 431. A conical part 210 is provided at the bottom end of the filter tank 200. The bottom end of the conical part 210 is fixedly connected to the receiving cavity 230. A neck portion 220 is provided between the 10 and the receiving cavity 230. The bottom end of the outlet tube 431 is offset to one side. The liquid inlet 250 is tangent to the inner wall of the filter tank 200. The lifting drive module 440 includes a hydraulic rod 441, which is fixedly installed on the filter tank 200. The output end of the hydraulic rod 441 is fixedly connected to a ring seat 442. Two connecting rods 443 are fixedly connected between the ring seat 442 and the suction ring 410. The connecting rods 443 pass through the conical portion 210 and slide into the conical portion 210. Multiple notches 411 are provided on the outer wall of the suction ring 410.

[0030] In this embodiment, the hydraulic rod 441 drives the ring seat 442 to move up and down. The ring seat 442 drives the suction ring 410 to move up and down via the connecting rod 443. When the suction ring 410 moves upward, the through pipe 420 moves upward relative to the sleeve 430, and the second check valve 432 is in a closed state, thereby creating a negative pressure inside the suction ring 410 to attract the liquid, thus drawing the liquid and impurities into the sleeve 430. Subsequently, the suction ring 410 moves downward, the first check valve 421 closes, and the liquid in the sleeve 430 is discharged through the outlet pipe 431. With the inlet 250 in place, when the liquid is discharged from the outlet pipe 431, it causes the liquid to rotate on the conical part 210. The rotation of the liquid, combined with the conical shape of the conical part 210, causes impurities to gather towards the center and enter the receiving cavity 230 under the action of gravity. The neck part 220 reduces the interference of the rotating liquid on the receiving cavity 230, thus concentrating the impurities into the receiving cavity 230. When the suction ring 410 moves up and down, it sweeps the entire periphery of the filter screen cylinder 300, thereby achieving real-time cleaning of the filter screen cylinder 300.

[0031] Example 2

[0032] like Figures 1-5As shown, in this embodiment, a support frame 260 is fixedly connected to the inner wall of the filter tank 200. The support frame 260 is used to support the filter screen cylinder 300 and to seal the bottom end of the filter screen cylinder 300. A pressure plate 270 is provided at the top of the filter tank 200. The pressure plate 270 is used to seal the top of the filter screen cylinder 300 and the inner wall of the filter tank 200. A pressure ring 280 is fixedly connected to the inner wall of the cover 290. The pressure ring 280 is used to squeeze and limit the pressure plate 270.

[0033] In practice, the design of the pressure plate 270 and the cover 290 allows the cover 290 to be removed and the pressure plate 270 to be taken off directly, thereby enabling the replacement or maintenance of the filter cylinder 300 and facilitating the opening of the filter tank 200 for maintenance.

[0034] 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.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
