Description

Technical Field

[0001] This invention relates to the field of liquid chlorine pump technology, and in particular to a sealing structure for a liquid chlorine pump. Background Technology

[0002] A search revealed a Chinese patent (authorization announcement number CN209324652U) disclosing a pump sealing structure. This patented technology includes a pump body, with an outlet pipe at the upper end and an inlet pipe at the left end. A hanging rod is provided on the outer surface of the inlet pipe. A sealing sleeve is slidably fitted inside the inlet pipe. A connecting block is fixedly connected to the left end of the inlet pipe, and a guide sleeve is fixedly connected to the left end of the connecting block. A slider is slidably fitted inside the guide sleeve, and a locking block is fixedly connected to the lower end of the slider. A wire rope is fixedly connected to the upper end of the slider. A connector is slidably fitted inside the inlet pipe, and a submersible pipe is fitted to the outer side of the connector. A retaining ring is fixedly fitted to the outer side of the connector. The pump uses a sealing structure that achieves a sealing effect through the cooperation of a joint, sealing sleeve, and inlet pipe. Moreover, the joint can be installed by the cooperation of a locking block and a retaining ring, making the operation convenient and quick. It eliminates the need for traditional threaded connections and extends the service life of the inlet pipe. However, in actual application, the sealing effect of the liquid chlorine pump is not good, and air leakage is easy to occur in the pipeline after the liquid chlorine pump is turned off. Summary of the Invention

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] like Figures 1-4 As shown, the present invention provides a technical solution: a sealing structure for a liquid chlorine pump, including a pump 1, a first pipe 2 connected to the output end of the pump 1, a second pipe 3 fixedly connected to the bottom of the first pipe 2, a fixing block 5 fixedly connected to the bottom of the second pipe 3, connecting flanges 4 fixedly connected to both ends of the second pipe 3, a first through groove 11 provided inside the connecting flange 4, two baffles 12 symmetrically and slidably connected to the inner wall of the second pipe 3, a conical block 14 fixedly connected to the outer wall of each of the two baffles 12, and a second through groove 13 opened inside each of the two baffles 12.

[0022] In this embodiment, after the liquid chlorine pump is turned off, to prevent gas leakage in the pipeline, the cylinder 9 is started, pushing the top plate 10 to move upward, which in turn drives the two connecting shafts 15 to move upward and rotate at the same time. The two connecting shafts 15 push the two baffles 12 to move respectively. After the two baffles 12 move, they approach the two connecting flanges 4 respectively. At this time, the conical block 14 is inserted into the first through groove 11 in the connecting flange 4 to seal the two connecting flanges 4 and prevent the second pipeline 3 from leaking.

[0023] Example 2

[0024] like Figures 1-4 As shown, a cylinder 9 is fixedly connected inside the fixing block 5. The output end of the cylinder 9 extends into the interior of the second pipe 3 and is fixedly connected to a top plate 10. Two connecting shafts 15 are symmetrically rotatably connected to the top of the top plate 10, and the two connecting shafts 15 are rotatably connected to two baffles 12 respectively. A connecting block 16 is fixedly connected to the top of the top plate 10, and a fixing plate 17 is fixedly connected to the top of the connecting block 16. A first sealing ring 18 is fixedly connected to the top of the fixing plate 17, and a first sealing groove 19 is provided inside the first pipe 2 to cooperate with the first sealing ring 18. A second sealing ring 20 is fixedly connected to the bottom of the first pipe 2, and a second sealing groove 21 is provided inside the fixing plate 17 to cooperate with the second sealing ring 20. The conical block 14, the first sealing ring 18, and the second sealing ring 20 are all made of rubber. A base 6 is provided at the bottom of the fixing block 5, and a connecting plate 7 is fixedly connected to the outer wall of the fixing block 5. The connecting plate 7 and the base 6 are connected by a positioning screw 8.

[0025] In this embodiment, the fixing block 5 can be installed on the base 6 by the positioning screw 8, which facilitates the fixing of the liquid chlorine pump. When the pump 1 is started, the gas can flow in the first through groove 11 and the second through groove 13 in the second pipe 3. When the pump 1 is turned off, the cylinder 9 is started, which drives the top plate 10 to move upward, so that the connecting block 16 moves upward, and drives the fixing plate 17 to move upward, so that the first sealing ring 18 is inserted into the first sealing groove 19 and the second sealing ring 20 is inserted into the second sealing groove 21, thereby sealing the first pipe 2, making the liquid chlorine pump more airtight and preventing gas leakage.

[0026] Working principle:

[0027] like Figures 1-4 As shown, the fixing block 5 can be installed on the base 6 by the positioning screw 8, which facilitates the fixing of the liquid chlorine pump. When the pump 1 is started, the gas can flow in the first through groove 11 and the second through groove 13 in the second pipe 3. When the pump 1 is turned off, the starting cylinder 9 drives the top plate 10 to move upward, which in turn moves the connecting block 16 upward and drives the fixing plate 17 upward, so that the first sealing ring 18 is inserted into the first sealing groove 19 and the second sealing ring 20 is inserted into the second sealing groove 21, thereby sealing the first pipe 2. At the same time as the cylinder 9 is started, it drives the two connecting shafts 15 to move upward and rotate at the same time. The two connecting shafts 15 push the two baffles 12 to move respectively. After the two baffles 12 move, they approach the two connecting flanges 4 respectively. At this time, the conical block 14 is inserted into the first through groove 11 in the connecting flange 4 to seal the two connecting flanges 4 and prevent the second pipe 3 from leaking. This makes the liquid chlorine pump more airtight and greatly improves the operation quality and efficiency compared with the traditional device.

[0028] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
