Description

Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to a pipeline heater with a cleaning mechanism. Background Technique

A water spraying box 55 is fixedly provided on one side of the installation disk 53. The water spraying box 55 is used to spray scale remover. Organic acids are often contained in the scale remover, which can react with calcium and magnesium ions in the scale to form soluble salts, thereby dissolving the solid scale into a liquid state for easy removal;

[0027] As a further implementation of this solution, a plurality of evenly spaced nozzles 56 are fixedly provided on the surface and inner wall of the water spraying box 55. A liquid storage assembly 6 is fixedly provided on the rear end face of the connecting disk 5. Such a design sprays scale remover on the inner wall of the casing 1 and the surface of the pipeline heater body 2 through a plurality of nozzles 56, improving the cleaning efficiency of the device;

[0028] As a further implementation of this solution, the liquid storage assembly 6 includes a water collecting cylinder 61. A pressure gauge 62 is fixedly provided on the upper surface of the water collecting cylinder 61. A water supply pipe 63 is fixedly provided between the water spraying box 55 and the water collecting cylinder 61. A control valve 64 is fixedly provided on one side of the water supply pipe 63. Such a design can conveniently observe the air pressure on the inner wall of the water collecting cylinder 61 through the pressure gauge 62, facilitating the replenishment of the scale remover in the water collecting cylinder 61 and ensuring the stability of the operation of the nozzles 56;

[0029] As a further implementation of this solution, the support assembly 43 includes two support blocks 431. The two support blocks 431 are respectively fixedly arranged at one end of the corresponding sliding rods 42. A support rod 432 is fixedly arranged between the two sliding rods 42. One side of the support rod 432 is fixedly connected to the other end of the connecting rod 44. A support frame 433 is fixedly arranged at the bottom end of one of the support blocks 431. A bottom plate 434 is fixedly provided at the bottom end of the support frame 433. Universal wheels 435 are fixedly provided on both sides of the bottom end of the bottom plate 434. The universal wheels 435 are used to contact the supporting ground. The support rod 432 and the support frame 433 support the sliding rod 42 while not hindering its movement;

[0030] As a further implementation of this solution, a limit sleeve 401 is fixedly arranged on the front end face of the connecting plate 40. The limit sleeve 401 is in sliding fit with the positioning rod 4, and a locking bolt 402 is threadedly connected to the top end of the limit sleeve 401. Such a design can achieve the limit fixation of the position of the connecting plate 40.

[0031] As a further implementation of this solution, push plates 421 are fixedly arranged at the other ends of the two sliding rods 42, and handles 422 are fixedly arranged on the surfaces of the push plates 421. Such a design can achieve moving the positions of the two sliding rods 42 by pulling the handles 422, facilitating the adjustment of the positions of the cleaning brush 54 and the water spraying box 55.

[0032] Working process: Before cleaning, fill an appropriate amount of inert gas and descaling agent into the inside of the water collecting cylinder 61 through the liquid injection port of the water collecting cylinder 61. The pressure gauge 62 can facilitate observing the air pressure on the inner wall of the water collecting cylinder 61. After adding, tighten the sealing cover. Then, push the connecting plate 40 to move towards the limiting block 3. When the connecting plate 40 moves, it drives the sliding rods 42, the connecting rod 44, and the connecting disk 5 to move synchronously. When the connecting plate 40 fits against the limiting block 3 and the connecting pipe 52 corresponds to the position of the flange on the front end face of the machine shell 1, at this time, tighten the locking bolt 402 so that the bottom end of the locking bolt 402 abuts against the upper surface of the positioning rod 4, thereby restricting the movement of the limit sleeve 401 and the connecting plate 40.

[0033] In order to insert the mounting disk 53 and the water spraying box 55 into the inside of the machine shell 1, pull the two sliding rods 42 to move through the handle 422 and the push plate 421. The two sliding rods 42, through the cooperation of the support assembly 43, the connecting disk 5, and the two arc plates 51, enable the connecting pipe 52 to be inserted into the inside through the flange at the front end of the machine shell 1. At this time, open the control valve 64, and the descaling agent in the water collecting cylinder 61 is transported to the inside of the water spraying box 55 through the water supply pipe 63. The nozzles 56 on the surface and the inner wall of the water spraying box 55 are used to spray the descaling agent on the inner wall of the machine shell 1 and the surface of the pipe heater body 2 on the moving path to decompose the water scale. Under the reciprocating movement of the sliding rod 42, the cleaning brush 54 contacts and rubs against the surface of the pipe heater body 2, thereby accelerating the shedding of the water scale.

[0034] After cleaning, move the mounting disk 53 and the water spraying box 55 out of the inside of the machine shell 1, and move the connecting plate 40 in the direction away from the limiting block 3, so as not to hinder the subsequent flushing operation of the pipe heater with the cleaning mechanism.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
