Description

Technical Field

[0001] The utility model relates to the technical field of workshop filter installation, in particular to an installation structure of a workshop exhaust filter. Background Art

[0002] Filters are usually used in workshop exhaust systems to treat the discharged waste gas. The function of these filtering devices is to reduce the emissions of particulate matter, dust, chemical substances or other pollutants in the waste gas to meet environmental protection standards and protect the surrounding environment and the health of workers.

[0003] Generally, the filter is installed at the pipe orifice, and then a fixing structure is used to fix the filter on the pipe; for example, an exhaust device for a slaughter processing workshop disclosed in the patent application number CN202322250958.3 records that by pulling the U-shaped grip on the positioning frame, the spring is compressed. The compression of the spring drives the movable plate to move, and the positioning rod on the movable plate is retracted into the support hole to disassemble and replace the filter mesh frame.

[0004] Although the above comparative document can realize the installation of the filter mesh frame, it is necessary to operate the U-shaped grips on both sides at the same time. Then, after placing the filter mesh frame into the exhaust box, the U-shaped grips need to be released at the same time. This process actually requires two people to cooperate synchronously, so it has limitations. Content of the Utility Model

A filter is arranged at the pipe orifice. When installing the filter, the filter is in contact with the square frame. Slots are opened on both sides of the filter, and insertion openings corresponding to the positions of the slots are opened on the side wall of the pipe. An insertion bar is movably inserted into the insertion opening. One end of the insertion bar is fixedly connected to a base bar, and two elastic telescopic rods are fixedly connected between the base bar and the side wall of the pipe. The other end of the insertion bar is movably inserted into the slot;

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Please refer to Figures 1 to 6 , the present invention provides a technical solution: a workshop exhaust filter screen installation structure, including a pipeline 1 and a square frame 3 fixed at the pipe orifice 101. A filter screen 2 is arranged at the pipe orifice 101. When installing the filter screen 2, the filter screen 2 is in contact with the square frame 3. Slots 201 are opened on both sides of the filter screen 2. The slots 201 are rectangular slots. Sockets 102 corresponding to the positions of the slots 201 are opened on the side wall of the pipeline 1. An insert bar 4 is movably inserted into the socket 102. One end of the insert bar 4 is fixedly connected to a base bar 6. Two elastic telescopic rods 5 are fixedly connected between the base bar 6 and the side wall of the pipeline 1. The other end of the insert bar 4 is movably inserted into the slot 201. The insert bar 4 is a rectangular rod;

[0028] A positioning bar 7 is fixedly connected to the side wall of the pipeline 1. An opening 701 is opened on the positioning bar 7. A rotating shaft 9 is rotatably inserted into the base bar 6. A stopper 8 is fixedly connected to the rotating shaft 9. A knob 10 is fixedly connected to the end of the rotating shaft 9. By rotating the knob 10, the stopper 8 is located inside the opening 701. At this time, the base bar 6 is limited, so that the end of the insert bar 4 is located outside the slot 201, thus facilitating the taking and placing of the filter screen 2.

[0029] Specifically, the elastic telescopic rod 5 includes a fixed sleeve 503 fixed to the side wall of the base bar 6 and an insert rod 501 movably inserted into the fixed sleeve 503. The other end of the insert rod 501 is fixedly connected to the outer side wall of the pipeline 1. A spring 502 is fixedly connected between the end of the insert rod 501 and the inner wall of the fixed sleeve 503.

[0030] When installing the filter screen 2, place the filter screen 2 inside the pipe orifice 101. The filter screen 2 is in contact with the square frame 3. Then rotate the knob 10 so that the stopper 8 moves out of the opening 701. At this time, the base bar 6 is no longer restricted, and the spring 502 releases its elastic force, pulling the fixed sleeve 503 and the base bar 6 towards the pipeline 1, so that the end of the insert bar 4 is inserted into the slot 201. At this time, the purpose of locking the filter screen 2 is achieved. The above operation process only requires one person to operate, which is more convenient.

[0031] When the filter screen 2 needs to be disassembled, pull the pull rod 11 to move the base strip 6 away from the pipe 1. At this time, rotate the knob 10 so that the end of the base strip 6 enters the opening 701. The base strip 6 abuts against the inner wall of the opening 701, and the limit of the base strip 6 is realized at this time. And at this time, the end of the insertion strip 4 is located outside the socket 102, and then the filter screen 2 can be removed from the pipe orifice 101.

[0032] In this solution, the width of the opening 701 is greater than the thickness of the stop block 8, so as to ensure that the stop block 8 can be smoothly rotated into the opening 701.

[0033] In order to facilitate the traction of the base strip 6 to realize linear displacement, a pull rod 11 is fixedly connected to the front side of the base strip 6, that is, by pulling the pull rod 11, it is convenient to pull the base strip 6.

[0034] In order to facilitate the taking and placing of the filter screen 2 from the pipe orifice 101, two pull handles 12 are fixedly connected to the front side wall of the filter screen 2. By holding the two pull handles 12, the filter screen 2 can be carried and operated.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
