Description

Technical Field

[0001] This utility model belongs to the technical field of gas filter, specifically a gas filter. Background Technology

[0002] In a gas-fired heating system, the gas filter acts as a robust defense, bearing the crucial responsibility of filtering out various impurities from the gas. Through its filtration structure, it blocks impurities from entering the gas, ensuring that the gas entering the heating equipment is as pure as possible, thus laying a solid foundation for the stable operation of the heating system.

[0003] Currently, most gas filters use filter screens to filter gas. However, the adsorption and interception effects of filter screens are limited. Furthermore, the gas inlet pipes are generally perpendicular to the filter structure when entering the gas, resulting in a dense contact point between the gas and the filter structure. This causes gas to accumulate in the contact area, which in turn fails to effectively remove moisture and impurities from the gas, thus affecting the filtration effect. Utility Model Content

[0004] This utility model provides a gas filter that can effectively solve the problem in the prior art where the gas filter has dense contact points with the filter structure, resulting in poor filtration effect: A gas filter includes a settling box, an interception box, and a filter box connected in sequence by pipes. A connecting cover is screwed to the side of the settling box away from the interception box, and an inclined air inlet pipe is fixedly connected to the outside of the connecting cover. An arc-shaped mesh cover is fixedly connected to one end of the inclined air inlet pipe inside the settling box, and several guide arc plates are connected to the outside of the arc-shaped mesh cover. An inclined condensation plate is fixedly installed inside the settling box.

[0005] As a further technical solution of this utility model, the bottom of the settling tank is inclined, and a drain pipe with a switch is installed at the bottom.

[0006] As a further technical solution of this utility model, the front and rear walls of the settling box, the interception box and the filter box are all connected to a connecting plate, and the bottom sides of the connecting plate are fixedly connected to support feet.

[0007] As a further technical solution of this utility model, a filter assembly is inserted into the interception box. The filter assembly includes a fixing plate, and slot plates are fixedly connected to both sides of the bottom of the fixing plate. An interception filter is snapped between the two slot plates, and fixing bolts are threaded to both sides of the fixing plate.

[0008] As a further technical solution of this utility model, the card slot plate and the interception filter are both located inside the interception box, and the side of the card slot plate is provided with a concave card slot.

[0009] As a further technical solution of this utility model, the fixing plate is located on the top of the interception box and is fixed to the interception box by fixing bolts.

[0010] As a further technical solution of this utility model, an exhaust pipe is installed on the top of the filter box, a switch valve is installed on the exhaust pipe, and a connecting cover is fastened to the side of the filter box away from the interception box. An impurity box is fixedly installed at the bottom of the interception box, and a switch plate is installed at the bottom of the impurity box.

[0011] As a further technical solution of this utility model, a connector is fixedly installed on one side of the inside of the filter box, and a dispersion tube is fixedly connected inside the connector. Several air holes are opened on the outside of the dispersion tube, and a filter sleeve is wrapped around the outside of the dispersion tube. A threaded section is opened on the outer wall of the end of the dispersion tube, and a movable ring for limiting one end of the filter sleeve is connected to the external thread of the threaded section. A limiting ring for limiting the other end of the filter sleeve is also fixedly installed on the outside of the dispersion tube.

[0012] As a further technical solution of this utility model, the connecting cover plate is fixedly installed on one side inside the filter box with a limiting seat. The limiting seat is recessed, and the end of the dispersion tube is closed and located inside the limiting seat.

[0013] As a further technical solution of this utility model, when the movable ring abuts against one end of the filter sleeve, it is at the end of the threaded section.

[0014] The beneficial effects of this utility model are as follows: By setting an inclined air inlet pipe in conjunction with an arc-shaped mesh cover and multiple guide arc plates on its exterior, this utility model can guide and disperse the gas when it enters the settling tank, so that the condensing plate can fully contact the gas and remove the moisture in the gas. This avoids the situation where the gas enters directly onto the condensing plate, resulting in dense contact points and insufficient moisture removal. When used in conjunction with the dispersion tube, the gas enters the dispersion tube and is discharged through various vents to contact the filter sleeve for filtration. This allows for thorough filtration of the gas, enabling the filter sleeve to be used extensively for gas filtration and effectively increasing the utilization area of ​​the filter sleeve. Furthermore, by setting a movable ring, the movable ring can move on the surface of the threaded section by rotation. In conjunction with the limiting ring, the filter sleeve can be fixed. When the movable ring moves on the surface of the threaded section, it can be removed, which makes it easy to replace the filter sleeve. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figures 1-7 As shown, a gas filter includes a settling box 1, an interception box 4, and a filter box 5 connected in sequence by pipes. A connecting cover 2 is screwed to the side of the settling box 1 away from the interception box 4, and an inclined air inlet pipe 3 is fixedly connected to the outside of the connecting cover 2. An arc-shaped mesh cover 7 is fixedly connected to one end of the inclined air inlet pipe 3 inside the settling box 1, and several guide arc plates 8 are connected to the outside of the arc-shaped mesh cover 7. An inclined condensation plate 9 is fixedly installed inside the settling box 1.

[0020] The bottom of the settling tank 1 is inclined, and a drain pipe with a switch is installed at the bottom. This facilitates the guidance of condensate into the drain pipe and then out of it.

[0021] The front and rear walls of the settling tank 1, the interception tank 4, and the filter tank 5 are all connected to a connecting plate, and support feet are fixedly connected to both sides of the bottom of the connecting plate. The support feet facilitate the support of the entire filter and make it easier to discharge impurities.

[0022] A filter assembly 10 is inserted into the interception box 4. The filter assembly 10 includes a fixing plate 101. The bottom sides of the fixing plate 101 are fixedly connected to the slot plates 102. An interception filter 103 is snapped between the two slot plates 102. The fixing plate 101 is threaded with fixing bolts 104 on both sides.

[0023] Both the card slot plate 102 and the interception filter 103 are located inside the interception box 4, and the side of the card slot plate 102 is provided with a recessed card slot.

[0024] By setting the slot plate 102 to engage the intercepting filter 103, the intercepting filter 103 can be removed through the slot plate 102 after the fixing plate 101 is removed, thus facilitating the replacement and cleaning of the intercepting filter 103.

[0025] The fixing plate 101 is located on the top of the interception box 4 and is fixed to the interception box 4 by fixing bolts 104.

[0026] An exhaust pipe is installed on the top of the filter box 5, and a switch valve is installed on the exhaust pipe. A connecting cover plate 17 is fastened to the side of the filter box 5 away from the interception box 4. An impurity box 6 is fixedly installed at the bottom of the interception box 4, and a switch plate is installed at the bottom of the impurity box 6.

[0027] A connector 11 is fixedly installed on one side of the inside of the filter box 5, and a dispersion tube 12 is fixedly connected inside the connector 11. Several air holes 19 are opened on the outside of the dispersion tube 12, and a filter sleeve 14 is wrapped around the outside of the dispersion tube 12. A threaded section 16 is opened on the outer wall of the end of the dispersion tube 12, and a movable ring 15 for limiting one end of the filter sleeve 14 is threadedly connected to the outside of the threaded section 16. A limiting ring 13 for limiting the other end of the filter sleeve 14 is also fixedly installed on the outside of the dispersion tube 12.

[0028] The limit ring 13 is set to work with the movable ring 15 to fix the filter sleeve 14. The movable ring 15 can move, which makes it easy to remove and facilitates the subsequent replacement of the filter sleeve 14.

[0029] A limiting seat 18 is fixedly installed on one side of the connecting cover plate 17 inside the filter box 5. The limiting seat 18 is recessed, and the end of the dispersion tube 12 is closed and located inside the limiting seat 18.

[0030] When the movable ring 15 abuts against one end of the filter sleeve 14, it is at the end of the threaded section 16, so that the connection between the movable ring 15 and the dispersion tube 12 remains flat, thereby ensuring the sealing performance.

[0031] A gas filter, in use, firstly introduces external gas into the interior of the settling tank 1 through the inclined inlet pipe 3. After being dispersed by the arc-shaped mesh cover 7, it is guided to the surface of the condenser plate 9 by various guide arc plates 8. Water vapor in the gas comes into contact with the surface of the condenser plate 9 to form condensate. Then, it is guided to the bottom of the settling tank 1 through the surface of the condenser plate 9. After that, the gas enters the interior of the interception box 4, where it passes through the interception filter screen 103 to intercept the impurities it carries. Then, it enters the filter box 5, enters the interior of the dispersion pipe 12 through the connector 11, is dispersed through various air holes 19, and is then filtered by the filter sleeve 14, thus realizing the gas filtration operation.

[0032] During assembly, the filter sleeve 14 is first fitted onto the outside of the dispersion tube 12 to cover each air hole 19. Then, the movable ring 15 is rotated to fix the filter sleeve 14 on the surface of the dispersion tube 12. One end of the filter sleeve 14 abuts against the limiting ring 13. After the connecting cover plate 17 is installed, one end of the dispersion tube 12 is located inside the limiting seat 18, which improves its stability. The filtered gas is discharged from the exhaust pipe. By connecting the exhaust pipe to the pipeline, the gas can be delivered to the equipment that needs to be used.

[0033] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
