Description

A Teflon diversion device for hot waste gas Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a Teflon diversion device for hot waste gas. Background Technology

[0002] The wastewater, waste gas, and waste residue discharged from laboratories are collectively referred to as the "three wastes" of laboratories. Due to the different experimental content of each laboratory, the toxicity and quantity of the chemical substances contained in these three wastes vary considerably. To ensure the health of laboratory personnel and prevent environmental pollution, they need to be treated. Laboratory waste gas includes inorganic and organic waste gases; generally, organic waste gases are treated using activated carbon adsorption and photocatalytic purification methods, while inorganic waste gases are treated using packed spray towers.

[0003] In the prior art, when treating waste gas, if the waste gas concentrates and enters the equipment during the treatment process, it can cause excessive local treatment volume, which can easily lead to untimely treatment and affect the treatment effect. To address the above problem, the document with application number 202420553251.1 discloses a flow guiding structure for waste gas treatment, which includes a connecting pipe. The connecting pipe has a vertical rod rotatably connected inside. The outer wall of the vertical rod is fixedly fitted with multiple circular sleeves. The outer walls of the multiple circular sleeves are fixedly connected to the same first semicircular plate. The outer wall of the vertical rod is rotatably connected with multiple sliding sleeves. The outer walls of the multiple sliding sleeves are fixedly connected to the same second semicircular plate. The outer wall of the connecting pipe is fixedly connected with an installation frame. This utility model is constructed by setting up a vertical rod, a circular sleeve, a first semicircular plate, a sliding sleeve, a second semicircular plate, a rubber ring, a mounting frame, a circular ring, a connecting block, a cylinder, a U-shaped block, an elliptical groove, and an electric push rod. The operation of the electric push rod causes the first and second semicircular plates to rotate relative to each other, forming an opening and closing process. After the exhaust gas enters, it is dispersed through the opening and closing process of the first and second semicircular plates, avoiding the concentrated flow of exhaust gas and facilitating subsequent treatment of the exhaust gas.

[0004] The above-mentioned patent has the following problems when used: In actual use, some of the exhaust gases are corrosive, so the pipeline needs to be maintained regularly. However, the existing connecting pipe is fixed by flanges and multiple bolts, which complicates the installation and disassembly process, increases time and labor costs, and requires tools to operate, thus greatly reducing the convenience of maintenance for workers. There is room for improvement.

[0005] Therefore, this application proposes a Teflon diversion device for hot waste gas to solve the above problems.

[0006] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a Teflon-coated diversion device for hot waste gas.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0015] Preferably, one end of each of the two worm gears passes through the two housings and is fixedly connected to a rotating plate, allowing the operator to rotate the two worm gears.

[0016] Preferably, the second collar is adapted to and in close contact with the first collar. One end of each of the two ring plates is provided with a second groove, and a sealing gasket is fixedly installed in each of the two second grooves to improve the sealing performance and prevent air leakage. Both ends of the two take-up rollers are fixedly fitted with a first bearing.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a Teflon-coated flow guiding device for hot exhaust gas. Referring to Figures 1-4, a Teflon-coated flow guiding device for hot exhaust gas includes a hot exhaust gas guiding pipe 1, a ring plate 2, and a fixing mechanism 5.

[0028] Both ends of the hot exhaust gas guide pipe 1 are welded with ring plates 2. One end of the hot exhaust gas guide pipe 1 is welded with a collar 3. The collar 3 is sealed on one of the two ring plates 2. One end of the hot exhaust gas guide pipe 1 is provided with a fixing mechanism 5, which is connected to the collar 3.

[0029] The fixing mechanism 5 includes a second collar 51, a housing 52, a take-up roller 53, a steel cable 54, a worm gear 55, a worm 56, and a rotating plate 57. The second collar 51 is fitted onto the ring plate 2. Both ends of the second collar 51 are fixedly connected to the housing 52. Steel cables 54 are installed inside both housings 52. Both steel cables 54 are connected to the first collar 3. Through the coordinated design of the hot exhaust gas guide pipe 1, the ring plate 2, the first collar 3, the fixing block 4, and the fixing mechanism 5, it is only necessary to assemble the ring plate 2 at one end of the hot exhaust gas guide pipe 1 with the first collar 3 on the other hot exhaust gas guide pipe 1. Then, the second collar 51 is installed on the corresponding two ring plates 2, and the rotating plate 57 is manually rotated to limit and fix it, thereby achieving the effect of quick assembly between the hot exhaust gas guide pipes 1, which greatly improves convenience and efficiency.

[0030] In this embodiment, both housings 52 are rotatably connected to take-up rollers 53, and the two ends of the two steel cables 54 are respectively fixedly wound around the two take-up rollers 53 for winding the two steel cables 54, thereby making the two steel cables 54 tighten the two fixed blocks 4.

[0031] In this embodiment, both steel cables 54 pass through both housings 52 and are connected to fixing blocks 4. The two fixing blocks 4 are welded to both ends of the collar 3. Both fixing blocks 4 have grooves 6. The two steel cables 54 are installed in the two grooves 6. The two grooves 6 can limit the movement of the two steel cables 54 and prevent them from moving.

[0032] In this embodiment, a worm gear 55 is fixedly sleeved on one end of each of the two take-up rollers 53, and a worm 56 is meshed on each of the two worm gears 55. The two worms 56 are rotatably connected to the two housings 52 respectively. By means of the inherent characteristics between the worm 56 and the worm gear 55, the take-up rollers 53 are limited.

[0033] In this embodiment, one end of each of the two worm gears 56 passes through the two housings 52 and is fixedly connected to a rotating plate 57, allowing the operator to rotate the two worm gears 56.

[0034] In this embodiment, the second collar 51 is adapted to the first collar 3 and is in close contact with it. One end of each of the two ring plates 2 is provided with a second groove, and a sealing gasket is fixedly installed in each of the two second grooves to improve the sealing performance and prevent air leakage. Both ends of the two take-up rollers 53 are fixedly fitted with a first bearing. The outer walls of the four first bearings are respectively fixedly connected to the two housings 52 to facilitate the rotation of the two take-up rollers 53.

[0035] In this embodiment, the inner side of the hot exhaust gas guide pipe 1 is coated with Teflon, and both sealing gaskets are also coated with Teflon. The Teflon coating can improve the high temperature resistance and corrosion resistance of the hot exhaust gas guide pipe 1 and the two sealing gaskets, thereby increasing their service life. A conical guide plate (not shown in the figure) is installed inside the hot exhaust gas guide pipe. The conical guide plate, through its conical structure and the function of the air holes, causes the hot exhaust gas to spread outwards when passing through, thereby further improving the guiding effect. The conical guide plate is coated with Teflon. The specific structure and working principle of the conical guide plate can be referred to the document with application number 202420553251.1, which is prior art and will not be described in detail here.

[0036] Working principle: In use, firstly, install the annular plate 2 at one end of the hot exhaust gas guide pipe 1 into the collar 3 at one end of the other hot exhaust gas guide pipe 1. Then, fit the collar 51 onto its corresponding two annular plates 2. Next, install the two steel cables 54 into the two grooves 6 on the two fixing blocks 4 respectively. Then, by rotating the two rotating plates 57 in sequence, the two worm gears 56 rotate on the two housings 52 respectively. During this process, the worm gears 56 and the worm wheel 55 transmit power, causing the worm wheel 55 to drive... The rotating take-up roller 53 rotates on the housing 52, causing the take-up roller 53 to wind up the steel cable 54. At this time, the steel cable 54 interacts with the fixed block 4, causing the collar 2 51 to move towards the collar 1 3 and abut against it. Thus, the two steel cables 54 and the two fixed blocks 4 can mutually limit and fix the collar 2 51. At the same time, the interaction between the collar 2 51 and the collar 1 3 and the corresponding two ring plates 2 can achieve the effect of limiting the hot exhaust gas guide pipe 1.

[0037] Conversely, this allows for the rapid disassembly of the hot exhaust gas guide pipe 1.

[0038] In summary, the hot exhaust gas guide pipe 1 can be quickly disassembled and assembled without the need for tools.

[0039] The technological advancement of this utility model compared to the prior art is that the hot exhaust gas guide pipe 1 can be quickly disassembled and assembled without the aid of tools through the cooperation of various components, which greatly improves the convenience of maintenance of the hot exhaust gas guide pipe 1 by the staff. Moreover, the structure is simple and more practical.

[0040] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
