Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a single-cylinder filter. Background Technology

[0002] A single-cartridge filter is a commonly used device for filtering liquids or gases, widely applied in industries such as manufacturing, chemicals, food, beverages, and pharmaceuticals. It consists of a filter cartridge and a sealed structure, primarily used to remove particles, impurities, or contaminants from fluids to ensure the normal operation of equipment, pipelines, or systems. The filter element of a single-cartridge filter is typically made of high-efficiency filter media (such as stainless steel mesh, fiber materials, activated carbon, etc.).

[0003] The working principle of a single-cylinder filter is based on physical filtration. When liquid or gas flows through the filter, the fluid first enters the inlet section. Then, as the fluid passes through the filter media, larger particles, impurities, or contaminants are intercepted, while clean liquid or gas flows out through the outlet. However, traditional single-cylinder filters mostly rely on manual replacement of the filter element, which usually requires disassembling the equipment, removing the old filter element, and replacing it with a new one. This is not only time-consuming and cumbersome, but also reduces production efficiency due to equipment downtime for maintenance. Therefore, the single-cylinder filter was proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a single-cylinder filter, which aims to improve the problem that most traditional single-cylinder filters in the prior art rely on manual operation to replace the filter element. This usually requires disassembling the equipment, removing the old filter element, and replacing it with a new one. This is not only time-consuming and cumbersome, but also reduces production efficiency due to the need for equipment downtime for maintenance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a single-cylinder filter, comprising a body, a top cover attached to the upper part of the body, four insert rods fixedly connected to the bottom of the top cover, a connecting block slidably connected to the outside of the insert rods, elastic clips fixedly connected to both sides of the bottom of the insert rods, a connecting member fixedly connected to the bottom of the connecting block, and a squeezing component slidably connected to both sides of the inside of the connecting member. The squeezing component is used to prevent the elastic clips from hooking onto the connecting block, and one protruding end of the elastic clip is attached to the bottom of the connecting block.

[0006] As a further description of the above technical solution:

[0007] The device is equipped with a filter element inside, and an air inlet valve is fixedly connected to one side of the device. An air vent is opened inside the device, and an aeration disc is fixedly connected to the bottom side of the device. The aeration disc communicates with the air vent. A backwash valve is fixedly connected to one side of the bottom of the device.

[0008] As a further description of the above technical solution:

[0009] The extrusion assembly includes a push rod that is slidably connected to both sides of the connector. One end of the push rod is fixedly connected to a pressing block, and a spring is sleeved on the outer side of the push rod.

[0010] As a further description of the above technical solution:

[0011] One end of the spring is fixedly connected to the outside of the connector, and the other end of the spring is fixedly connected to one side of the pressing block.

[0012] As a further description of the above technical solution:

[0013] A water inlet valve is fixedly connected to the upper side of the top cover, and a vortex plate is fixedly connected to the upper inside of the body.

[0014] As a further description of the above technical solution:

[0015] A drain valve is fixedly connected to the bottom of the filter element, and a sewage valve is fixedly connected to one side of the drain valve.

[0016] As a further description of the above technical solution:

[0017] Both the backwash valve and the drain valve have an external connecting valve and a flow meter fixedly connected to one side of their interiors.

[0018] As a further description of the above technical solution:

[0019] A support is fixedly connected to the bottom of the device.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when the filter element needs to be replaced, pressing the pressing block squeezes the spring, causing the push rod to slide and squeeze the elastic clip, pulling up the top cover, causing the insertion rod to slide and drive the elastic clip to move out of the connecting block, thus realizing quick and convenient filter element replacement and improving the maintenance efficiency of the equipment.

[0022] 2. In this utility model, liquid is introduced through the inlet valve and guided by the vortex plate to form a vortex, so that the liquid flows evenly on the surface of the filter element, improving the filtration effect. After filtration, the liquid flows out through the drain valve, and dirt and impurities are discharged through the drain valve. When the filtration effect of the filter element decreases, air is sent to the ventilation chamber through the air inlet valve and enters the aeration disc to aerate the filter element. At the same time, liquid is sent through the backwash valve to backwash the filter element under the action of aeration. This realizes efficient filtration of liquid, self-cleaning of the filter element and restoration of filtration effect, improves the efficiency and service life of the filtration equipment, and reduces the frequency and cost of filter element replacement.

[0028] 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.

[0029] Reference Figure 1 and Figure 3 An embodiment of this utility model provides a single-cylinder filter, including a body 1, a top cover 3 attached to the upper part of the body 1, four insert rods 4 fixedly connected to the bottom of the top cover 3, a connecting block 6 slidably connected to the outside of the insert rods 4, elastic clips 5 fixedly connected to both sides of the bottom of the insert rods 4, a connecting member 7 fixedly connected to the bottom of the connecting block 6, and a squeezing component slidably connected to both sides of the inside of the connecting member 7. The squeezing component is used to prevent the elastic clips 5 from hooking onto the connecting block 6, and one side of the protruding end of the elastic clip 5 is attached to the bottom of the connecting block 6.

[0030] The extrusion assembly includes a push rod 9, which is slidably connected to both sides inside the connector 7. One end of the push rod 9 is fixedly connected to a pressing block 8, and a spring 10 is sleeved on the outer side of the push rod 9. One end of the spring 10 is fixedly connected to the outer side of the connector 7, and the other end of the spring 10 is fixedly connected to one side of the pressing block 8. A bracket 2 is fixedly connected to the bottom of the body 1.

[0031] When the filter element 18 needs to be replaced, the pressing block 8 is pressed, which compresses the spring 10. At the same time, the push rod 9 slides inside the connector 7. As the push rod 9 slides, pressure is applied to the protruding end of the elastic clip 5, and then the top cover 3 is pulled upward. During the pulling of the top cover 3, the insert rod 4 slides inside the connector 6. At the same time, the previous compression of the protruding end of the elastic clip 5 causes the elastic clip 5 to be moved out of the connector 6. When the elastic clip 5 is completely removed from the connector 6, the top cover 3 is separated from the body 1, and the filter element 18 can be easily removed for replacement. This achieves the purpose of quickly and conveniently replacing the filter element 18, greatly improving the maintenance efficiency of the equipment.

[0032] Reference Figure 1 and Figure 2 The filter element 18 is installed inside the body 1. An air inlet valve 12 is fixedly connected to one side of the inside of the body 1. An air vent 16 is opened inside the body 1. An aeration disc 17 is fixedly connected to the bottom inside the body 1 and communicates with the air vent 16. A backwash valve 13 is fixedly connected to one side of the bottom of the body 1. A water inlet valve 11 is fixedly connected to one side of the upper part of the top cover 3. A vortex plate 19 is fixedly connected to the upper inside of the body 1. A drain valve 14 is fixedly connected to the bottom end of the filter element 18. A sewage discharge valve 15 is fixedly connected to one side of the drain valve 14. An external connecting valve 20 and a flow meter 21 are fixedly connected to one side of the inside of both the backwash valve 13 and the drain valve 14.

[0033] Liquid is smoothly introduced into the container 1 through the inlet valve 11. The vortex plate 19 guides the liquid, creating a vortex that allows for uniform flow across the surface of the filter element 18. This uniform flow improves the filtration effect, ensuring more thorough and effective filtration. After filtration, the pure liquid flows out through the drain valve 14, while dirt and impurities are discharged through the drain valve 15. Over time, the filtration efficiency of the filter element 18 may gradually decrease. At this point, the air inlet valve 12 begins to function, introducing gas into the ventilation chamber 16. The liquid enters the aeration disc 17 and aerates the filter element 18. At the same time, the backwash valve 13 sends liquid into the body 1. Under the aeration action of the aeration disc 17, the liquid backwashes the filter element 18. This backwashing process can effectively remove impurities and contaminants accumulated on the filter element 18, restoring its filtration effect and achieving high-efficiency filtration of the liquid. It also enables the filter element 18 to have a self-cleaning function, allowing it to maintain a good filtration effect, extending its service life, improving the efficiency of the filtration equipment, reducing the frequency of filter element 18 replacement, and thus reducing costs.

[0034] Working principle: When the device is needed, liquid is introduced into the body 1 through the inlet valve 11. The liquid is guided by the vortex plate 19 to form a vortex, which makes the liquid flow evenly on the surface of the filter element 18, improving the filtration effect. After filtration, the liquid flows out through the drain valve 14, while dirt or impurities are discharged through the drain valve 15. When the filtration effect of the filter element 18 decreases, gas is sent into the ventilation chamber 16 through the air inlet valve 12, and then into the aeration disc 17 to aerate the filter element 18. At the same time, liquid is sent into the body 1 through the backwash valve 13. Under the aeration action of the aeration disc 17, the filter element 18 is backwashed, restoring its filtration effect. This achieves efficient filtration of liquid, self-cleaning of the filter element 18, and restoration of its filtration effect, improving the efficiency and service life of the filtration equipment and reducing the frequency and cost of replacing the filter element 18.

[0035] When the filter element 18 needs to be replaced, pressing the pressing block 8 squeezes the spring 10, causing the push rod 9 to slide inside the connector 7 and squeeze the protruding end of the elastic clip 5. Then, pulling the top cover 3 upwards causes the insertion rod 4 to slide inside the connector 6, simultaneously moving the elastic clip 5 out of the connector 6 and separating it from the body 1. This allows the filter element 18 to be removed and replaced quickly and conveniently, improving the maintenance efficiency of the equipment.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
