Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a suction-type multi-element self-cleaning filter. Background Technology

[0002] In fields such as industrial production, water treatment, and agricultural irrigation, filters are key devices for removing impurities from fluids. Their filtration efficiency and ease of operation and maintenance directly affect production continuity and fluid quality.

[0003] Traditional filters require the filter element to be removed for cleaning after prolonged filtration, which is a cumbersome process. Some filters can use backwashing to backwash the filter element, but in actual use, the filtration process needs to be paused during backwashing, which affects the filtration process and reduces filtration efficiency. Therefore, a suction-type multi-element self-cleaning filter is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a suction-type multi-element self-cleaning filter to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a suction-type multi-element self-cleaning filter, comprising: Filter tank, liquid is passed into the filter tank for filtration; A filter assembly is disposed inside a filter tank and is used to filter liquids. A backwash assembly is located inside the filter tank, and the filter components are backwashed by the backwash assembly. A drain assembly is located inside the lower part of the filter tank. When the backwash assembly performs backwashing, the dirt is discharged through the drain assembly.

[0006] Furthermore, the bottom outer surface of the filter tank is connected to an inlet pipe, and one side of the middle section of the filter tank is connected to an outlet pipe.

[0007] Furthermore, the filter assembly includes a pressure plate and a baffle, both of which are disposed inside the filter tank. Multiple filter elements are installed between the pressure plate and the baffle. Several flow ports are provided on the outer surface of the pressure plate, through which liquid enters the filter elements for filtration.

[0008] Furthermore, differential pressure gauges are installed at both the inlet and outlet pipes.

[0009] Furthermore, the backwash assembly includes multiple backwash tubes, one end of which penetrates through the filter tank, and the other ends of the multiple backwash tubes extend into the interior of multiple filter elements respectively.

[0010] Furthermore, the sewage discharge assembly includes a rotating shaft, one end of which rotatably passes through the top outer surface of the filter tank, and the other end of which rotatably passes through a pressure plate and a baffle. A mounting bracket is installed on the top outer surface of the filter tank, and a motor is installed on the outer surface of the mounting bracket. The output end of the motor is connected to the rotating shaft. A connecting pipe is fixedly connected to the bottom outer surface of the rotating shaft, and a transmission pipe is connected to the outer surface of the connecting pipe. A sewage discharge pipe is connected to the bottom outer surface of the filter tank, and the connecting pipe rotatably connects to the inside of the sewage discharge pipe.

[0011] Furthermore, the inner diameter of the transmission tube is larger than the diameter of the flow port.

[0012] Compared with the prior art, the beneficial effects of this utility model are: When a pressure difference is formed between the fluid in the inlet pipe and the outlet pipe, the motor drives the rotating shaft to rotate the connecting pipe, causing the transmission pipe to rotate to the flow port and close the flow port. Then, water is transported to the backwash pipe to backwash the filter element. The impurities backwashed are discharged through the transmission pipe, connecting pipe and drain pipe. At the same time, another filter component continues to perform filtration. Thus, through multi-filter filtration, each group of filter elements is cleaned in sequence, achieving efficient cleaning, while other filter elements are unaffected and continue normal filtration.

[0015] 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. Example 1:

[0016] Please refer to the following: Figs. 1-3This utility model provides a technical solution: a suction-type multi-element self-cleaning filter, including a filter tank 100, filter components, a backwash component, and a drain component. Liquid is introduced into the filter tank 100 for filtration. The filter components are located inside the filter tank 100 and filter the liquid. The backwash component is located inside the filter tank 100 and backwashes the filter components. The drain component is located at the bottom of the filter tank 100 and discharges dirt through it during backwashing. Specifically, liquid is delivered into the filter tank 100 and filtered by the filter components. When impurities accumulate to a certain level, the backwash component backwashes the filter components, and the backwashed dirt is discharged through the drain component. During backwashing, the drain component can block the filter components that need backwashing, allowing other filter components to perform normal filtration.

[0017] Furthermore, the bottom outer surface of the filter tank 100 is connected to an inlet pipe 101, and the outer surface of one side of the middle section of the filter tank 100 is connected to an outlet pipe 102. Specifically, the liquid is transported to the inside of the filter tank 100 through the inlet pipe 101 for filtration, and discharged from the filter tank 100 through the outlet pipe 102.

[0018] Furthermore, the filter assembly includes a pressure plate 200 and a baffle 201, both of which are disposed inside the filter tank 100. Multiple filter elements 203 are installed between the pressure plate 200 and the baffle 201. Several flow ports 202 are provided on the outer surface of the pressure plate 200. Liquid enters the filter element 203 through the flow ports 202 for filtration. Specifically, the liquid enters the interior of the filter element 203 through the flow ports 202 and is filtered by the filter element 203. The filtered impurities remain on the inner wall of the filter element 203. Multi-element filtration is performed by multiple filter elements 203, and the filter elements 203 can be backwashed sequentially during subsequent backwashing, thus not affecting the normal filtration operation.

[0019] Furthermore, differential pressure gauges are installed at both the inlet pipe 101 and the outlet pipe 102. Specifically, the filtered impurities will remain on the inner wall of the filter element 203. As the impurities accumulate, a pressure difference will be formed between the inner and outer sides of the filter element 203. The pressure difference is determined by the pressure gauge interface at the inlet pipe 101 and the pressure gauge interface at the outlet pipe 102. When the pressure difference reaches a certain value, the backwashing component will start to perform backwashing.

[0020] Furthermore, the backwash assembly includes multiple backwash pipes 300, one end of which penetrates the filter tank 100, and the other ends of the multiple backwash pipes 300 extend into the interior of multiple filter elements 203 respectively. Specifically, during backwashing, high-pressure water is delivered to the corresponding backwash pipe 300, and the filter element 203 is backwashed by the high-pressure water flow. The dirt enters the connecting pipe 402 through the transmission pipe 404 and is filtered by multiple filter elements. During backwashing, each group of filter elements 203 is cleaned in sequence for efficient cleaning, while other filter elements 203 are unaffected and continue normal filtration.

[0021] Furthermore, the sewage discharge assembly includes a rotating shaft 401. One end of the rotating shaft 401 rotatably passes through the top outer surface of the filter tank 100, and the other end of the rotating shaft 401 rotatably passes through the pressure plate 200 and the baffle 201. A mounting bracket is installed on the top outer surface of the filter tank 100, and a motor 400 is installed on the outer surface of the mounting bracket. The output end of the motor 400 is connected to the rotating shaft 401. A connecting pipe 402 is fixedly connected to the bottom outer surface of the rotating shaft 401. A transmission pipe 404 is connected to the outer surface of the connecting pipe 402. A sewage discharge pipe 403 is connected to the bottom outer surface of the filter tank 100, and the connecting pipe 402 rotatably connects to the inside of the sewage discharge pipe 403. Specifically, when the pressure difference reaches a certain value, the control system activates the motor 400, which drives the shaft 401 to rotate. The shaft 401 then rotates the connecting pipe 402, causing the transmission pipe 404 to rotate to the corresponding flow port 202, thus sealing the flow port 202. The backflushed dirt enters the connecting pipe 402 through the transmission pipe 404 and is discharged through the drain pipe 403. At the same time, another filter element continues to perform filtration. This multi-element filtration process cleans each filter element 203 sequentially and efficiently, while other filter elements 203 remain unaffected and continue normal filtration.

[0022] Furthermore, the inner diameter of the transmission tube 404 is larger than the diameter of the flow port 202. Specifically, by making the inner diameter of the transmission tube 404 larger than the diameter of the flow port 202, the transmission tube 404 can be rotated to a position corresponding to the flow port 202 to cover and seal the flow port 202.

[0023] Working Principle: In use, liquid is delivered to the interior of the filter tank 100 through the inlet pipe 101 and enters the interior of the filter element 203 through the flow port 202. The liquid is filtered by the filter element 203, and the filtered impurities remain on the inner wall of the filter element 203. The filtered liquid is discharged through the outlet pipe 102. As impurities accumulate, a pressure difference is formed between the inner and outer sides of the filter element 203. The pressure difference is determined by the pressure gauge interfaces at the inlet pipe 101 and the outlet pipe 102. When the pressure difference reaches a certain value, the control system activates the motor 400. The motor 400 drives the rotating shaft 401 to rotate, which in turn drives the connecting pipe 402 to rotate. This causes the transmission pipe 404 to rotate to the corresponding flow port 202, sealing the flow port 202. High-pressure water is then delivered to the corresponding backwash pipe 300, where the filter element 203 is backwashed. Dirt enters the connecting pipe 402 through the transmission pipe 404 and is discharged through the drain pipe 403. At the same time, another filter component continues to perform filtration. This multi-element filtration process ensures that each filter element 203 is cleaned sequentially and efficiently, while other filter elements 203 remain unaffected and continue normal filtration.

[0024] The control system is an existing structure, and the control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the field and will only be used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0025] 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.
