[0003] Currently, the main challenges facing shell-and-tube coolers are the presence of impurities in the cooling water. Over time, the mineral deposits within the cooling water form scale, which not only increases the risk of corrosion but also further impairs heat transfer. Furthermore, operators often have difficulty visually determining whether there is blockage within the cooling pipes, which undoubtedly increases the difficulty of maintenance and inspection. Utility Model Content

This not only makes it convenient for the staff to judge whether the cooling pipe is blocked due to scale, but also can clean the scale in the cooling pipe when the cooling pipe is blocked due to scale.

[0020] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.
[0021] like Figures 1-6 The cooler self-cleaning device of the utility model shown in the figure includes temperature sensors 8 respectively installed on the input end and output end of the cooling pipe 5 in the cooler 4, a feeding pipe 1 is provided on the outer wall of the cooling pipe 5, the two feeding pipes 1 are respectively located at the input end and the output end of the cooling pipe 5, the two temperature sensors 8 are located between the two feeding pipes 1, a blocking plate 11 is sealingly and slidingly connected in the feeding pipe 1, the blocking plate 11 is used to close the cooling pipe 5, a cavity 12 is provided in each of the blocking plates 11, a connecting hole 13 that is connected to the cavity 12 is provided on the side wall of the blocking plate 11 facing the temperature sensor 8, a through hole 7 that is connected to the cavity 12 is provided on the side wall of the blocking plate 11 away from the cooling pipe 5, a driving mechanism for driving the blocking plate 11 to move toward the cooling pipe 5 is provided on the feeding pipe 1, and the two temperature sensors 8 are electrically connected to the two driving mechanisms respectively.
[0022] The driving mechanism includes a cylinder 2 installed on the outer wall of the feed pipe 1, and a push rod 9 is fixed to the end of the piston rod of the cylinder 2. One end of the push rod 9 passes through the feed pipe 1 and is fixed to the side wall of the blocking plate 11 away from the temperature sensor 8. A rectangular long hole 10 is provided on the outer wall of the feed pipe 1, and the rectangular long hole 10 is located between the top and the bottom of the blocking plate 11. When the device is in use, the piston rod of the cylinder 2 is controlled to extend, and the push rod 9 is driven to move in the rectangular long hole 10 toward the cooling pipe 5, thereby driving the blocking plate 11 to move toward the cooling pipe 5, so that the blocking plate 11 contacts the inner wall of the cooling pipe 5, thereby sealing the cooling pipe 5. By fixing a feeding device 3 to the feeding pipe 1 at the input end of the cooling pipe 5, and electrically connecting the feeding device 3 to the temperature sensor 8, and by having the temperature sensor 8 send an electrical signal to the driving mechanism while also sending an electrical signal to the feeding device 3, it is possible to facilitate the staff to inject a scale remover mixed with water into the feeding pipe 1 at the input end of the cooling pipe 5. By detachably fixing a recovery box 6 to the feeding pipe 1 at the output end of the cooling pipe 5, the recovery box 6 can be used to collect the materials cleared from the cooling pipe 5, making it convenient for the staff to uniformly process the cooling pipe 5 after cleaning. By configuring the blocking plate 11 and the push rod 9 as an integrated structure, the stability of the device during use can be improved, and the blocking plate 11 and the push rod 9 can be prevented from detaching during use.
[0023] Combined with attachment Figure 1-6It can be seen that the method of using the present invention is as follows: First, the temperature of the input end and the output end of the cooling tube 5 in the cooler 4 are detected by the temperature sensors 8 respectively installed on the input end and the output end of the cooling tube 5 in the cooler 4. When the temperature of the input end of the cooling tube 5 in the cooler 4 is higher than the temperature of the output end of the cooling tube 5 in the cooler 4 by a certain value, the temperature sensor 8 will send an electrical signal to the cylinder 2 and the feeding device 3 to control the piston rod of the cylinder 2 to extend, so that the push plate moves in the rectangular long hole 10, driving the blocking plate 11 toward the cooling tube 5. The input and output ends of the cooling pipe 5 are closed, and the scale remover mixed with water is injected into the feed pipe 1 at the input end of the cooling pipe 5 through the feeding device 3, so that the scale remover can enter the cavity 12 through the through hole 7 on the inner plugging plate 11 of the feed pipe 1 at the input end of the cooling pipe 5, and then enter the connecting hole 13 on the inner plugging plate 11 of the feed pipe 1 at the input end of the cooling pipe 5 from the cavity 12, so that the scale remover can enter the cooling pipe 5, contact with the scale in the cooling pipe 5 to produce a chemical reaction, and produce carbon dioxide. Carbon and soluble salts are removed and then enter the cavity 12 along with the scale remover through the connecting hole 13 on the inner plugging plate 11 of the feeding pipe 1 at the output end of the cooling pipe 5, and then enter the connecting hole 13 on the inner plugging plate 11 of the feeding pipe 1 at the output end of the cooling pipe 5 from the cavity 12, so that the soluble salts are discharged from the cooling pipe 5 to the recovery box 6 along with the scale remover. When the temperature at the input end of the cooling pipe 5 is not much different from the temperature at the output end of the cooling pipe 5, the temperature sensor 8 will send an electrical signal to the feeding device 3 and the cylinder 2 to control the feeding. The device 3 stops injecting the scale remover mixed with water into the feed pipe 1 at the input end of the cooling pipe 5, controls the piston rod of the cylinder 2 to retract, and moves the push plate in the rectangular long hole 10, driving the blocking plate 11 to move back to the initial position in the direction away from the cooling pipe 5, thereby opening the input and output ends of the cooling pipe 5, allowing the cooler 4 to work normally again, and then remove the recovery box 6 from the feed pipe 1 at the output end of the cooling pipe 5. After the cooling pipe 5 is cleaned, the materials cleaned out of the cooling pipe 5 are uniformly processed.
