Description

Technical Field

[0001] This patent relates to the field of support pile technology, specifically a new type of gas filter. Background Art

[0002] Gas filters are mainly used at the front end of gas pressure regulating equipment, metering equipment, valves and other equipment to filter and separate impurities (rust, dust, etc.) in the gas flow, thereby protecting downstream pipelines and equipment from contamination, blockage, and damage, and thus protecting the normal operation of the equipment. However, the filter element in the filter is generally a cylindrical type. Under the premise that the outer ring is a filter, the internal flow pipe diameter will be reduced to varying degrees, so that when the flow rate is relatively large, there is a situation of too fast flow rate, which in turn affects the service life of the filter element. In addition, under the condition of large flow, the overall volume of the filter will become larger, increasing the cost of use. For this reason, we propose a new type of gas filter.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0018] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 This patent provides a technical solution: a new type of gas filter, including a cylinder 1, the left and right ends of the side wall of the cylinder 1 are respectively embedded with an inlet pipe 2 and an outlet pipe 3, a circular ring 4 is integrally formed on the top of the outer wall of the cylinder 1, and a sealing cover 5 is connected to the top of the circular ring 4 through a screw and a nut, a rectangular ring 6 is integrally formed on the right side of the inner wall of the cylinder 1, and a rubber ring 7 is bonded to the left side of the rectangular ring 6, a mounting ring 8 is arranged in the cylinder 1, a filter element 9 is installed in the mounting ring 8, a horizontal plate 10 is fixedly installed on the top side of the right side of the mounting ring 8, a hole body is arranged on the horizontal plate 10, a bolt 11 is arranged in the hole body, and the bottom end of the bolt 11 is screwed to the top of the outer wall of the rectangular ring 6, and the right side of the mounting ring 8 is tightly fitted to the left side of the rubber ring 7;

[0019] The filter element 9 is a rectangular structure with no difference between the inner and outer diameters. Therefore, the air inlet pipe 2 and the air outlet pipe 3 are pipes of the same diameter, thereby avoiding the problem of reducing the diameter to ensure the filtration efficiency. In addition, the air inlet pipe 2 and the air outlet pipe 3 are not inserted too much into the cylinder body 1, thereby ensuring the volume inside the cylinder body 1, which can make the circulation effect of the entire gas system better.

[0020] A removable cover 12 is screwed to the bottom end of the cylinder 1 .

[0021] The gas entering the cylinder 1 and the dust in the gas can be intercepted by the filter element 9 and fall into the removable cover 12, so that the dust can be easily cleaned.

[0022] Specifically, the filter element 9 includes a filter screen 13 , wherein the filter screens 13 are multiple and the multiple filter screens 13 are stacked together.

[0023] The traditional cylindrical filter element is changed into a rectangular filter screen 13. At the same time, in order to achieve a higher filtering area, the number of filter screens 13 is increased, and the number of layers between them is folded each other, so that the filter element has a larger filtering area and meets the filtering area requirements of large-diameter filters.

[0024] Specifically, the mounting ring 8 includes a first ring body 14 and a second ring body 15 , the inner side walls of which are both provided with an annular groove 16 , the first ring body 14 and the second ring body 15 are aligned with each other, and mounting parts 17 are provided at the upper and lower ends of the first ring body 14 and the second ring body 15 .

[0025] like Figure 3 As shown, a plurality of filter screens 13 are located in two annular grooves 16 to clamp the filter screens 13 .

[0026] Specifically, the mounting member 17 includes a fixing plate 18 and a fixing ring 19, which are fixedly mounted on the second ring body 15 and the first ring body 14 respectively. A through opening 20 is provided on the inner wall of the fixing ring 19. A rocker arm 21 is hinged on the left side of the fixing plate 18 through a hinge. The left end of the rocker arm 21 passes through the fixing ring 19 and is integrally formed with a circular plate 22. A spring 23 is sleeved on the side wall of the rocker arm 21. The left end of the spring 23 is fixedly mounted on the right side of the circular plate 22. A slip ring 24 is fixedly mounted on the right end of the spring 23. The right side of the slip ring 24 is tightly fitted on the left side of the fixing ring 19, and the right side of the first ring body 14 is tightly fitted on the left side of the second ring body 15.

[0027] like Figure 4 As shown, Figure 4 for Figure 3 An enlarged view of the middle upper mounting member 17 shows that the lower mounting member 17 and the upper mounting member 17 are symmetrically distributed.

[0028] The spring 23 is in a compressed state. The compression elasticity of the spring 23 causes the slip ring 24 to be pressed against the fixing ring 19 . The fixing ring 19 is installed on the first ring body 14 , so the first ring body 14 is pressed against the left side of the second ring body 15 .

[0029] When disassembling the first ring body 14 and the second ring body 15 , the slip ring 24 can be moved leftward to separate from the fixed ring 19 , and then the swing rod 21 is rotated around the hinge point between the fixed plate 18 and the swing rod 21 to separate from the fixed ring 19 through the opening 20 .

[0030] Specifically, a positioning groove 25 is provided on the left side of the fixing ring 19 , and a positioning block 26 is integrally formed on the right side of the slip ring 24 , and the positioning block 26 is inserted into the positioning groove 25 .

[0031] By providing the positioning block 26 inserted into the positioning groove 25, the swing rod 21 can be prevented from turning over along the hinge point.

[0032] Specifically, the side wall of the swing rod 21 is in relative contact with the inner wall of the fixing ring 19 .

[0033] The side wall of the swing rod 21 is in relative contact with the inner wall of the fixing ring 19, so that the connection between the swing rod 21 and the fixing ring 19 can be more tightly connected.

[0034] Working principle: The fuel gas enters the filter through the inlet pipe 2. Under the obstruction of the filter element 9, the impurities (rust, dust, etc.) in the gas are blocked and sink into the removable cover 12 at the bottom. When there are too many impurities, they can be cleaned through the removable cover 12. Since the filter element 9 is a rectangular parallelepiped structure, there is no difference between the inner and outer diameters. Therefore, the inlet pipe 2 and the outlet pipe 3 are pipes of the same diameter, thus avoiding the problem of reducing the diameter to ensure the filtration efficiency. In addition, the inlet pipe 2 and the outlet pipe 3 are not inserted too much into the cylinder 1, ensuring the volume inside the cylinder 1, which can make the circulation effect of the entire gas system better.

[0035] When replacing the filter element 9, the cover 5 can be removed, the bolts 11 can be removed, and the mounting ring 8 can be taken out from the cylinder 1. The slip ring 24 can be moved to the left to make the slip ring 24 detach from the fixed ring 19, and then the swing rod 21 can be rotated with the hinge point of the fixed plate 18 and the swing rod 21 as the axis, and the swing rod 21 can be detached from the fixed ring 19 through the through hole 20, and then the first ring body 14 and the second ring body 15 can be separated, and the internal filter 13 can be replaced.
