Description

Technical Field

[0001] The utility model relates to the technical field of natural gas separation filters, in particular to an impact-resistant natural gas separation filter that is convenient for maintenance. Background Technique

[0002] Natural gas is a clean energy source. When transporting between pipelines and equipment, special separation filters are required to filter fixed impurities in the transport medium to ensure the normal operation of the equipment and the cleanliness of the air.

[0003] Most of the existing natural gas separation filters are disposable products. Due to their long cylinders, the structures such as the filter screens deep inside cannot be effectively cleaned. After filtering a large amount of deposited impurities, they are directly scrapped and cannot be reused, resulting in a waste of resources and environmental pollution problems in dealing with old filters, bringing certain economic losses and environmental burdens.

[0004] Therefore, aiming at the problem that the existing natural gas separation filter cannot effectively clean and maintain the deep inside, resulting in the scrapping of the product after a period of use and unable to be reused, thus causing waste of resources and environmental pollution problems in dealing with old filters, bringing certain economic losses and environmental burdens, an impact-resistant natural gas separation filter that is convenient for maintenance can be designed. It can drive the lifting ring to move up and down in the filter element body by using a threaded rod and cooperating with a guide rod. The lifting ring pushes the mounting ring and the mounting plate to descend, so that the cleaning bristles on the mounting plate can effectively clean the impurities attached to the inner wall of the filter element body, facilitating maintenance, extending its service life, avoiding waste of resources, reducing environmental pollution problems in dealing with old filters, saving usage costs, and reducing the burden on the environment. Content of the Utility Model

[0005] In order to overcome the problem that the existing natural gas separation filter cannot effectively clean and maintain the deep inside, resulting in the scrapping of the product after a period of use and unable to be reused, thus causing waste of resources and environmental pollution problems in dealing with old filters, bringing certain economic losses and environmental burdens.

[0006] The technical solution of the utility model is: an impact-resistant natural gas separation filter element that is convenient for maintenance, including a filter element body; it also includes a threaded rod, a guide rod, a lifting ring, an installation ring, an installation plate and cleaning bristles. The upper and lower ends of the filter element body are respectively fixedly connected with an upper end cover and a lower end cover. The left and right ends of the inner side of the lower end cover are fixedly connected with fixed angle blocks. A threaded rod is rotatably connected between the left fixed angle block and the upper end cover, and a guide rod is fixedly connected between the right fixed angle block and the upper end cover. A lifting ring is slidably arranged inside the filter element body. The threaded rod threadedly penetrates and connects the left end of the lifting ring, and the guide rod movably penetrates and connects the right end of the lifting ring. An installation ring is arranged below the lifting ring, and an installation plate is arranged below the installation ring.

[0007] Preferably, by rotating the threaded rod and cooperating with the guide rod, the lifting ring is driven to move up and down in the filter element body. The lifting ring drives the installation ring to descend, and the installation ring drives the installation plate to descend synchronously. During the process, the cleaning bristles on the side of the installation plate clean the inner wall of the filter element body, push off the accumulated impurities, and push them out from the opening of the lower end cover. Thus, the impurities attached to the inner wall of the filter element body that are difficult to handle are effectively cleaned, which is convenient for maintenance, maintains the good filtering effect of the filter element body, extends its service life, can be used multiple times, thus avoiding waste of resources, and at the same time reducing the environmental pollution problem of dealing with old filter elements, saving the use cost, and reducing the burden on the environment.

[0008] As a preference, a limiting rotation groove is opened on the outer arc of the lifting ring, and a limiting sliding ring is slidably arranged in the limiting rotation groove. The limiting sliding ring can freely rotate in the limiting rotation groove and is restricted in position to prevent falling.

[0009] As a preference, a connecting ring is fixedly connected to the bottom of the limiting sliding ring. The bottom of the connecting ring passes through the limiting rotation groove and is fixedly connected to the upper end of the installation ring. The connecting ring connects the installation ring and the limiting sliding ring. Thus, the installation ring can rotate together with the limiting sliding ring.

[0010] As a preference, an accommodation groove is opened on the outer arc of the installation ring. The cross-section of the installation plate is arranged in an L shape, and the installation plate is convenient to fit on the outer bottom of the installation ring.

[0011] As a preference, there are four installation plates, and each installation plate is fixedly connected to the bottom of the installation ring through two groups of bolts. The four installation plates form a complete ring. Thus, the four external cleaning bristles can complete the cleaning of the filter element body, and it is convenient to disassemble and replace, which is convenient for deeply cleaning the cleaning bristles used for a long time.

[0012] Preferably, a circular groove is provided on the left side of the upper end of the upper end cover. A rotating block is rotatably connected in the circular groove.

A tool is inserted into the hexagonal card slot to drive the rotating block to rotate, so as to conveniently drive the threaded rod to rotate through the rotating block.

[0013] Preferably, a protective folding plate is fixedly connected between the upper end cover and the lower end cover. The filter element body is arranged inside the protective folding plate, and mesh holes are provided on the surface of the protective folding plate. The protective folding plate can protect the relatively fragile filter element body from being damaged by the impact of external objects. At the same time, the provided mesh holes can maintain the normal filtering function of the filter element body.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. By rotating the threaded rod and cooperating with the guide rod, the lifting ring is driven to move up and down in the filter element body. The lifting ring drives the mounting ring to descend, and the mounting ring drives the mounting plate to descend synchronously. During the process, the cleaning brush hairs on the side of the mounting plate clean the inner wall of the filter element body, push off the accumulated impurities, and push them out from the opening of the lower end cover, so as to effectively clean the inner wall of the filter element body that is difficult to handle, facilitate maintenance, maintain the good filtering effect of the filter element body, extend its service life, and can be used multiple times, thus avoiding waste of resources, reducing the environmental pollution problem of dealing with old filter elements, saving usage costs, and reducing the burden on the environment;
