Description

Technical Field

[0001] The utility model relates to the technical field of fuel gas filters, in particular to a fuel gas filter. Background Art

[0002] Gas filters are usually installed at the inlet of pressure reducing valves, pressure relief valves, positioning valves or other equipment to remove impurities in the medium to protect the normal use of valves and equipment and reduce equipment maintenance costs. When the fluid enters the filter with a filter element, its impurities are blocked by the filter element, and the clean filtered gas is discharged from the filter outlet. When filtering the gas, the impurities will be deposited on the filter plate and the activated carbon wheel. Long-term accumulation will reduce the filtration efficiency of the filter plate and the activated carbon wheel, and will reduce the filtration effect. Therefore, it is necessary to clean it to improve its filtration efficiency.

[0003] At present, Chinese patent announcement number CN203469711 U discloses a filter on a gas pipeline, including a vertical cylinder, an air inlet is provided on the cylinder, a filter element is vertically installed inside the cylinder, the bottom of the filter element is connected to the air outlet through an internal channel, and a pressure sensor is connected at the air inlet and the air outlet through a pipeline. The sensor transmits the sensed pressure to the differential pressure gauge, and the differential pressure gauge is arranged on the outside of the cylinder. When the filter is working, the degree of blockage of the filter element is determined according to the difference between the inlet pressure and the outlet pressure on the differential pressure gauge. When the value of the inlet pressure minus the outlet pressure is greater than a certain set value, the filter element is seriously blocked and needs to be cleaned.

[0004] However, although the device can determine whether blockage occurs in the gas filter through a differential pressure gauge, it does not solve the problem of how to clean it. Utility Model Content

[0005] Therefore, in view of the above problems, the utility model proposes a gas filter to solve the problem that the gas filter in the prior art is easily clogged and cannot be automatically cleaned.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A gas filter comprises a shell, wherein an air inlet and an exhaust port are respectively arranged on the left and right sides of the shell, and a cover plate is arranged on the top of the shell; a filter cartridge is arranged in the shell, and the filter cartridge comprises a cylinder body and a cylinder cover arranged on the cylinder body; and the bottom of the filter cartridge is connected with the exhaust port through an L-shaped pipe.

[0008] A vibration assembly is arranged in the filter cartridge, and the vibration assembly includes a rotating shaft, fan blades, a knocking assembly and a vibration ring; the rotating shaft is rotatably arranged at the center bottom of the cartridge cover, the fan blades are fixedly arranged on the rotating shaft, and the knocking assembly is arranged at the bottom of the rotating shaft.

[0009] The knocking assembly includes a limit frame, one end of the limit frame is fixedly connected to the rotating shaft, a sliding groove is provided on the side of the limit frame away from the rotating shaft, a moving rod is slidably arranged in the sliding groove, an end of the moving rod close to the rotating shaft is fixedly connected to a spring, an end of the spring close to the rotating shaft is fixedly connected to the limit frame, and an end of the moving rod away from the rotating shaft is fixedly connected to a knocking head.

[0010] The vibration ring is arranged in an annular shape on the inner side wall of the cylinder, and the vibration ring corresponds to the striking head. A plurality of protrusions are arranged on the inner side wall of the vibration ring.

[0011] Furthermore, the protrusion is hemispherical.

[0012] Furthermore, a cleaning assembly is provided, which includes a cleaning rod vertically arranged on the outside of the cylinder, bristles are provided on the side of the cleaning rod close to the cylinder, the top of the cleaning rod is fixedly connected to a cross bar, the cross bar is located above the cylinder cover, and the top of the rotating shaft passes through the cylinder cover and is fixedly connected to the cross bar.

[0013] Furthermore, pressure gauges are provided on both the air inlet and the air outlet.

[0014] Furthermore, a sewage outlet assembly is provided at the bottom of the shell, and the sewage outlet assembly includes a sewage pipe and a sewage valve.

[0015] By adopting the above technical solution, the beneficial effects of the utility model are:

[0016] By setting a vibration component, the fan blades are used to drive the rotation of the rotating shaft, and then the knocking component is driven to rotate. The knocking component is intermittently restricted by the protrusion, and the spring is constantly contracted and reset, thereby continuously knocking the inner wall of the cylinder, producing a vibrating effect on the cylinder, causing the accumulated dust on the cylinder to fall off, solving the problem of possible blockage of the filter cylinder; by setting a cleaning component, when the rotating shaft rotates, it drives the cross bar to rotate, thereby driving the cleaning rod to rotate around the periphery of the cylinder, and the bristles on the cleaning rod clean the dust attached to the surface of the cylinder, reducing the dust accumulation on the surface of the cylinder, making the cylinder less prone to blockage and improving its filtration efficiency; by setting pressure gauges on the air inlet and exhaust port, the degree of blockage inside the gas filter can be judged by the pressure difference measured by the two pressure gauges; by setting a sewage outlet component, it is used to clean the accumulated dust at the bottom of the shell.

When filtering the gas, the gas enters the housing 1 through the air inlet 11, and then enters the filter cylinder after being filtered through the filter holes on the cylinder 21 to remove impurities in the gas. The filtered gas is discharged from the exhaust port 12 through the L-shaped pipe 15. When it is necessary to clean the dust at the bottom of the housing 1, open the drain valve 17 to discharge the dust through the drain pipe 16.

During the rotation of the rotating shaft 31, the knocking assembly will intermittently hit the bump 34. When the knocking head 45 hits the bump 34, the bump 34 will generate an extrusion force on the knocking head 45, compressing the spring 44. When the knocking head 45 rotates over the bump 34, the spring 44 generates a rebound force on the moving rod 43, causing the knocking head 45 to hit the inner wall of the cylinder 21, thereby generating a vibration effect, causing the dust on the surface of the cylinder 21 to fall off, avoiding blockage; at the same time, the rotation of the rotating shaft 31 will also drive the cross bar 53 to rotate, thereby driving the cleaning rod 51 to rotate around the periphery of the cylinder 21, and the bristles 52 on the cleaning rod 51 clean the dust on the surface of the cylinder 21, further reducing the dust accumulation on the surface of the cylinder 21. The dust particles that are shaken off or swept off fall to the bottom of the cylinder 21 . When cleaning is required, the drain valve 17 is opened to discharge the dust through the drain pipe 16 .
