Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipeline technology in chemical workshops, and in particular relates to a dust prevention device for pipelines in chemical workshops. Background Technology
[0002] Chemical workshops generally consist of three parts: main production workshops, auxiliary production workshops, and production management facilities. At the same time, chemical workshops generate a large number of pollutants that are harmful to human health during the production process, resulting in serious indoor air pollution. Therefore, ventilation and air exchange measures such as exhaust fans and hoods are required, and corresponding ventilation ducts are used. In order to facilitate the entry of external air dust into the chemical workshop, corresponding dust prevention devices are installed at the ends of the ventilation ducts.
[0003] However, existing dust control devices, when installed inside pipelines, accumulate significant amounts of dirt and dust on their surfaces due to their constant exposure to outside air. Furthermore, they lack ease of disassembly and replacement, hindering their removal, replacement, or cleaning. Moreover, during disassembly and assembly, structural stability cannot be guaranteed, leading to wobbling and potential detachment. Therefore, we provide a pipeline dust control device for chemical workshops to address these problems. Utility Model Content
[0004] The purpose of this utility model is to provide a dustproof device for pipelines in chemical workshops. By rotating and adjusting the position of the abutting block driven by the abutting ring, the dustproof net can be disassembled, replaced, or cleaned. At the same time, the rubber ball slides along the ball opening to ensure that the abutting block stably abuts against the ring frame, so that the dustproof net is installed stably.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a dustproof device for pipelines in a chemical workshop, including an installation ring and a dustproof net located inside the installation ring; an abutment ring is rotatably provided on the front end face of the installation ring, and a collar is fixed on the periphery of the abutment ring and fitted onto the installation ring; the inner side wall of the collar has multiple ball openings evenly distributed in a ring; multiple rubber balls are fixed on the outer periphery of the installation ring and respectively rotatably disposed inside the ball openings; a ring frame is fixed on the periphery of the dustproof net and abuts against the inner side wall of the installation ring; multiple abutment blocks are fixed on the inner side wall of the abutment ring and evenly distributed in a ring, and the rear end face of the abutment block abuts against the front end face of the ring frame.
[0007] The present invention is further configured such that a pipe body is provided on the rear end face of the dustproof net, and the rear part of the mounting ring is slidably inserted into the interior position of the pipe body.
[0008] The present invention is further configured such that a plurality of locking plates are fixed around the dustproof net located in front of the pipe body in a ring-shaped evenly distributed manner, and the locking plates are bolted to the front end face of the pipe body.
[0009] The present invention is further configured such that an assembly ring is fixed on the inner side wall of the mounting ring, which abuts against the rear end face of the ring frame, and the inner diameter of the assembly ring is consistent with the mesh diameter of the dustproof net.
[0010] The present invention is further configured such that four positioning blocks are fixedly arranged in a ring on the front end face of the assembly ring, and the positioning blocks are all fixedly connected to the inner side wall of the mounting ring.
[0011] The present invention is further configured such that positioning holes are provided at the positions of the positioning blocks on the periphery of the ring frame, and each positioning block is slidably inserted into the corresponding positioning hole. The front end face of the positioning block is flush with the front end face of the ring frame, and the front and rear end faces of the abutment block are the same in shape and size as the end face of the positioning block.
[0012] The present invention is further configured such that a T-shaped opening is provided on the front end face of the mounting ring, and a T-shaped ring plate is fixedly and rotatably engaged inside the T-shaped opening on the rear end face of the abutting ring.
[0013] This utility model has the following beneficial effects:
[0014] 1. When using this utility model, the abutting ring is rotated to control the abutting plate to drive the abutting block to rotate and move to the position of the positioning block and the positioning port. Thus, the abutting block no longer limits the abutting of the ring frame. At this time, the dustproof net can be removed from the inside of the installation ring by sliding along the positioning block and the abutting block through the positioning port, so as to disassemble, replace or clean the dustproof net.
[0015] 2. In use, when the abutting ring rotates, it drives the collar to slide along the circumference of the mounting ring. The collar also drives the rubber balls to rotate out and in one by one inside the ball opening. When the abutting ring stops rotating, the ball opening limits the rubber balls. Therefore, the abutting ring and collar cannot rotate automatically without external force, thus ensuring the stability of the abutting ring and ensuring that the abutting blocks stably abut against the ring frame, making the dustproof net installation stable.
[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1
[0028] Please see Figures 1 to 6This utility model is a dustproof device for pipelines in chemical workshops. The position of the abutment block 201 is adjusted by rotating the abutment ring 2, so as to disassemble, replace or clean the dustproof net 3. At the same time, the rubber ball block 104 slides along the ball opening 204 to ensure that the abutment block 201 stably abuts against the ring frame 301, so as to make the installation of the dustproof net 3 stable.
[0029] Specifically, the mounting ring 1 and the dustproof net 3 located inside the mounting ring 1 are characterized in that: an abutment ring 2 is rotatably provided on the front end face of the mounting ring 1, a collar 203 is fixed on the periphery of the abutment ring 2 and sleeved on the mounting ring 1, a plurality of ball openings 204 are evenly distributed in a ring on the inner side wall of the collar 203, a plurality of rubber ball blocks 104 are fixed on the outer periphery of the mounting ring 1 and respectively rotatably disposed inside the ball openings 204, a ring frame 301 is fixed on the periphery of the dustproof net 3 and abuts against the inner side wall of the mounting ring 1, a plurality of abutment blocks 201 are evenly distributed in a ring on the inner side wall of the abutment ring 2 and the rear end face of the abutment block 201 abuts against the front end face of the ring frame 301.
[0030] The operation process of this embodiment is as follows: Using the above-described structure, the dustproof net 3 is installed at the end of the pipe body 4. When external air enters the interior of the pipe body 4, the dustproof net 3 filters the dust in the air. When the dustproof net 3 needs to be disassembled, the abutment ring 2 can be rotated, thereby controlling the abutment plate to rotate and move the abutment block 201 to the position of the positioning block 102 and the positioning port 302. Thus, the abutment block 201 no longer limits the abutment against the ring frame 301. At this time, it can slide along the positioning block 102 and the abutment block 201 through the positioning port 302, thereby allowing the dustproof net 3 to be installed... The internal position of the mounting ring 1 is removed, allowing the dustproof net 3 to be disassembled, replaced, or cleaned. When the abutting ring 2 rotates, it drives the collar 203 to slide along the circumference of the mounting ring 1. The collar 203 also drives the rubber balls 104 to rotate out and in one by one inside the ball opening 204. When the abutting ring 2 stops rotating, the ball opening 204 limits the rubber balls 104. Therefore, the abutting ring 2 and the collar 203 cannot rotate automatically without external force, thus ensuring the stability of the abutting ring 2 and ensuring that the abutting block 201 stably abuts against the ring frame 301, making the installation of the dustproof net 3 stable.
[0031] Furthermore, according to Figure 2 , Figure 3 and Figure 4The front end face of the mounting ring 1 has a T-shaped opening 103, and the rear end face of the abutment ring 2 has a T-shaped ring plate 202 that is rotatably engaged inside the T-shaped opening 103. Since the T-shaped ring plate 202 is rotatably engaged inside the T-shaped opening 103, when the abutment ring 2 is controlled to rotate, the abutment ring 2 will drive the T-shaped ring plate 202 to rotate inside the T-shaped opening 103. At the same time, the T-shaped opening 103 limits the T-shaped ring plate 202 to ensure that the abutment ring 2 can be stably connected to the mounting ring 1.
[0032] Example 2
[0033] Please see Figure 2 , Figure 4 and Figure 5 Based on Example 1, the locking plate 105 is bolted to the end of the pipe body 4 to facilitate the installation of the mounting ring 1.
[0034] Specifically, the rear end face of the dustproof net 3 is provided with the pipe body 4, the rear part of the mounting ring 1 is slidably inserted into the internal position of the pipe body 4, and multiple locking plates 105 are fixed around the dustproof net 3 in front of the pipe body 4 in a ring-shaped evenly distributed manner, and the locking plates 105 are bolted to the front end face of the pipe body 4.
[0035] The operation process of this embodiment is as follows: When installing the mounting ring 1, the mounting ring 1 can be inserted into the pipe body 4, and the locking plate 105 can be connected to the end of the pipe body 4, so that the bolt can be passed through the locking plate 105, and the mounting ring 1 can be installed at the end of the pipe body 4 through the locking plate 105.
[0036] Example 3
[0037] Please see Figure 2 , Figure 4 and Figure 6 Based on Example 1, the positioning block 102 is positioned in the positioning port 302 to limit the ring frame 301 and ensure the stability of the dustproof net 3.
[0038] Specifically, the inner wall of the mounting ring 1 is fixed with an assembly ring 101 that abuts against the rear end face of the ring frame 301, and the inner diameter of the assembly ring 101 is the same as the mesh diameter of the dustproof net 3. The front end face of the assembly ring 101 is fixed with four positioning blocks 102 that are evenly distributed in a ring, and the positioning blocks 102 are all fixedly connected to the inner wall of the mounting ring 1. The circumference of the ring frame 301 is provided with positioning holes 302 at the positions corresponding to the positioning blocks 102. Each positioning block 102 is slidably inserted into the corresponding positioning hole 302, and the front end face of the positioning block 102 is flush with the front end face of the ring frame 301. The front and rear end faces of the abutment block 201 are the same in shape and size as the end faces of the positioning blocks 102.
[0039] The operation process of this embodiment is as follows: After the dustproof net 3 is placed inside the mounting ring 1, the ring frame 301 on the periphery of the dustproof net 3 will be in the mounting ring 1, so that the ring frame 301 abuts against the assembly ring 101, and the positioning port 302 on the periphery of the ring frame 301 is fitted onto the positioning block 102, so that the positioning block 102 directly limits the ring frame 301, thereby limiting the position of the dustproof net 3.
