Description

Technical Field

[0001] The utility model relates to the technical field of filter protection, and specifically relates to a filter protection structure. Background Art

[0002] A filter is an indispensable device on a pipeline for conveying a medium. It is usually installed at the inlet end of equipment such as a pressure reducing valve, a pressure relief valve, a constant water level valve, and other equipment. The filter is composed of a cylinder body, a stainless steel filter screen, a sewage discharge part, a transmission device, and an electrical control part. After the water to be treated passes through the filter cylinder of the filter screen, its impurities are blocked. When cleaning is required, as long as the detachable filter cylinder is taken out, and reinstalled after treatment, so it is extremely convenient to use and maintain.

[0003] Existing filters are directly installed on the pipeline for use, and they have no protection device. When the filter is impacted, it is easily damaged, thus shortening its service life, and there is a problem of poor protection performance. For this reason, we have proposed a filter protection structure to solve the above problems. Content of the Utility Model

[0004] In view of the above technical problems in the prior art, the utility model provides a filter protection structure, aiming to solve the above problems.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A filter protection structure includes a filter body, and a protection cylinder is sleeved outside the filter body. The protection cylinder is composed of two mirror-image arc-shaped plates that are movably connected. On the upper and lower sides of the inner side walls of the two arc-shaped plates, semi-circular blocks with a conical longitudinal section are respectively arranged in a mirror image. On the outer periphery of the filter body corresponding to the semi-circular blocks of the two arc-shaped plates, semi-fixed rings are respectively arranged in a mirror image. The semi-fixed rings on the two arc-shaped plates can be snap-fitted and fixed on the outer periphery of the filter body. A plurality of protection plates are annularly arranged around the two arc-shaped plates, and the plurality of protection plates are movably connected to the outer side walls of the arc-shaped plates.

[0007] Preferably, on one side of the protection plate corresponding to the outer periphery of the arc-shaped plate, four connecting columns are horizontally arranged. The four connecting columns pass through the arc-shaped plate and extend to the inner side of the arc-shaped plate, and are slidably connected thereto. At one end of the four connecting columns located inside the arc-shaped plate, limit blocks are respectively arranged. At one end of the four connecting columns located outside the arc-shaped plate, springs are sleeved. One end of the spring abuts against the protection plate, and the other end abuts against the arc-shaped plate.

[0008] Preferably, a buffer material is filled between the inner side of the arc-shaped plate and the filter body, and the limit block located inside the arc-shaped plate abuts against the buffer material.

[0009] Preferably, the buffer material is polyethylene foam plastic.

[0010] Preferably, a connecting belt is provided between adjacent said protective plates.

[0011] Preferably, one side of the abutting portion of the two arc-shaped plates is hinged to each other, and fixing blocks are respectively provided on the other side, and the two fixing blocks are fixedly connected by fastening bolts.

[0012] Preferably, the semi-circular block is made of rubber.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] A filter protection structure provided by the present utility model, two arc-shaped plates hinged to each other are fixed on the periphery of the filter body through the internal semi-circular block and semi-fixed ring, and are fastened by fastening bolts. When receiving a small-area impact, the single-force-bearing protective plate moves into the arc-shaped plate, and abuts against the buffer material through the spring and the limit block to slow down the impact. At the same time, when the single protective plate moves, through the connecting belt, the surrounding protective plates can play a pulling role on the impacted protective plate to further slow down the impact;

[0015] When receiving a large-area impact, it is borne by multiple protective plates at the same time to disperse the impact force. At the same time, the semi-circular block made of rubber cooperates with the polyethylene foam plastic buffer material to further slow down the impact force, minimize the impact received by the filter to the greatest extent, improve the filter protection performance, and extend its service life.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-3 , in the embodiment proposed by this application: a filter protection structure includes a filter body 1, and a protection cylinder is sleeved outside the filter body 1. The protection cylinder is composed of two mirror-image arc-shaped plates 2 movably connected. Among them, one side of the contact part of the two arc-shaped plates 2 is hinged, and fixed blocks 21 are respectively provided on the other side. The two fixed blocks 21 are fixedly connected by a fastening bolt 22. On the upper and lower sides of the inner side walls of the two arc-shaped plates 2, semi-circular blocks 3 with a conical longitudinal section are respectively mirror-image arranged to facilitate impact dispersion. The semi-circular blocks 3 are made of rubber material to facilitate impact mitigation. Semi-fixed rings 4 are respectively mirror-image fixed on the outer periphery of the filter body 1 corresponding to the semi-circular blocks 3 of the two arc-shaped plates 2. The semi-fixed rings 4 on the two arc-shaped plates 2 can be snap-fitted and fixed on the outer periphery of the filter body 1. A plurality of protection plates 5 are annularly arranged around the two arc-shaped plates 2, and the plurality of protection plates 5 are movably connected to the outer side walls of the arc-shaped plates 2;

[0022] The two hinged arc-shaped plates 2 are fixed on the outer periphery of the filter body 1 through the internal semi-circular blocks 3 and semi-fixed rings 4 and are tightened by the fastening bolt 22 to ensure the stability of the installation of the arc-shaped plates 2, and the installation and disassembly are convenient and fast. At the same time, the setting of the plurality of protection plates 5 mitigates the external impact, improves the protection performance of the filter body 1, and extends its service life.

[0023] In another embodiment, please refer to Figures 1-3 , on one side of the protection plate 5 corresponding to the outer periphery of the arc-shaped plate 2, four connecting columns 51 are horizontally provided. The four connecting columns 51 pass through the arc-shaped plate 2 and extend to the inner side of the arc-shaped plate 2 and are slidably connected thereto.
