Description

Technical Field

[0001] This utility model relates to the field of liquid chlorine production technology, specifically to a liquid chlorine pipeline filter installation structure. Background Technology

[0002] Liquid chlorine is a yellow-green oily liquid used as a raw material in the production of chloroacetic acid, epichlorohydrin, chlorinated paraffin, thionyl chloride, vinyl chloride, etc. The production process of liquid chlorine contains large solid impurities such as acid residue and rust. In order to filter out impurities, a filter screen is usually installed at the inlet of the liquid chlorine inlet pipe. After liquid chlorine is introduced for a long time, the impurities in the filter screen accumulate and affect the filtration effect. Therefore, the filter screen needs to be removed and replaced regularly.

[0003] Since the filter screen is installed inside the liquid chlorine inlet pipe, replacing the filter screen requires disassembling and separating the connecting clamps between the liquid chlorine inlet pipe and the delivery pipeline, and then removing and replacing the filter screen. This operation is cumbersome and affects the efficiency of screen replacement. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a liquid chlorine pipeline filter screen installation structure that can replace the filter screen without disassembling the pipeline, which is convenient to operate and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a liquid chlorine pipeline filter screen installation structure, comprising a liquid chlorine inlet pipe and a filter screen body, wherein the filter screen body is installed at the inlet of the liquid chlorine inlet pipe, the liquid chlorine inlet pipe is provided with a through hole, the filter screen body passes through the through hole, both ends of the filter screen body extend beyond the outer surface of the liquid chlorine inlet pipe, and fixing components for fixing the filter screen body are symmetrically arranged on the outer surface of the liquid chlorine inlet pipe.

[0006] As a preferred technical solution of this utility model, the fixing component includes a fixing box, a pressure plate and an adjusting bolt. The fixing box is fixed on the outer side of the liquid chlorine inlet pipe. Both ends of the filter screen body are located inside the fixing box and the lower surface of the filter screen body is in contact with the bottom surface inside the fixing box. The upper end of the fixing box is threaded with an adjusting bolt, and the lower end of the adjusting bolt is located inside the fixing box and is rotatably connected to the pressure plate through a bearing ring.

[0007] As a preferred embodiment of this utility model, one end of the filter screen body passes through the corresponding fixed box, and a disc is integrally connected to one end of the filter screen body. The disc and the fixed box are connected by fixing bolts.

[0008] As a preferred embodiment of this utility model, a handle is provided at one end of the disc.

[0009] As a preferred embodiment of this utility model, a first sealing ring is provided between the adjusting bolt and the fixed box.

[0010] As a preferred embodiment of this utility model, a second sealing ring is provided between the disc and the fixed box.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the installation structure of this liquid chlorine pipeline filter screen is reasonably designed and easy to operate. By passing the filter screen body through the liquid chlorine inlet pipe, and then fixing the filter screen body at both ends with fixing components, the filter screen body can be replaced simply by pulling out the filter screen body. There is no need to disassemble the pipeline for installation, which greatly improves work efficiency. Attached Figure Description

[0016] 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 (for ease of description and understanding, hereinafter referred to as...). Figure 1 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a liquid chlorine pipeline filter screen installation structure, including a liquid chlorine inlet pipe 1 and a filter screen body 2. The filter screen body 2 is installed at the inlet of the liquid chlorine inlet pipe 1. A through hole 4 is provided on the liquid chlorine inlet pipe 1. The filter screen body 2 passes through the through hole 4. The size of the filter screen body 2 matches that of the through hole 4. Both ends of the filter screen body 2 extend beyond the outer side of the liquid chlorine inlet pipe 1. Fixing components 3 for fixing the filter screen body 2 are symmetrically arranged on the outer side of the liquid chlorine inlet pipe 1.

[0018] The fixing assembly 3 includes a fixing box 31, a pressure plate 32, and adjusting bolts 33. The fixing box 31 is fixed to the outer side of the liquid chlorine inlet pipe 1. Both ends of the filter screen body 2 are located inside the fixing box 31, and the lower surface of the filter screen body 2 is in contact with the bottom surface inside the fixing box 31, so that the filter screen body 2 can be directly inserted into the fixing box 31. The upper end of the fixing box 31 is threadedly connected to the adjusting bolts 33. The lower end of the adjusting bolts 33 is located inside the fixing box 31, and the lower end of the adjusting bolts 33 is rotatably connected to the pressure plate 32 through a bearing ring. After the filter screen body 2 is inserted into place, the pressure plate 32 is pressed and fixed to the filter screen body 2 by rotating the adjusting bolts 33 at both ends.

[0019] To facilitate the fixing of the filter body 2, one end of the filter body 2 passes through the corresponding fixing box 31, and a disc 21 is integrally connected to one end of the filter body 2. When one end of the filter body 2 abuts against the other end of the fixing box 31, the disc 21 is in contact with the outer side of the fixing box 31 at the same end, and the disc 21 and the fixing box 31 are connected by fixing bolts 5.

[0020] To facilitate the removal of the filter body 2, a handle 22 is provided at one end of the disc 21.

[0021] To improve sealing and prevent liquid chlorine leakage, a first sealing ring 34 is provided between the adjusting bolt 33 and the fixed box 31, and a second sealing ring 6 is provided between the disc 21 and the fixed box 31.

[0022] When in use: When the filter body 2 needs to be replaced, stop the liquid chlorine flow, loosen the adjusting bolts 33 on the two fixing boxes 31 respectively, and then remove the fixing bolts 5 to pull out the filter body 2; insert the new filter body into the corresponding liquid chlorine inlet pipe 1, tighten the adjusting bolts 33 to fix the filter body 2, and then tighten the fixing bolts 5.
