Description

Technical Field

[0001] The utility model relates to a cleaning device, in particular to a cleaning device for the tube wall of a graphite heat exchanger. Background Technique

[0002] The graphite heat exchanger belongs to a shell-and-tube heat exchanger. Metatitanic acid flows through the tube side, and cooling water flows through the shell side. Vertical heat exchangers are mostly selected. The material enters from the lower part of the heat exchanger and flows out from the upper part of the heat exchanger or a partition is added. With the lower-in and upper-out mode, the heat exchange effect is good, and the graphite material also has good anti-corrosion and temperature resistance properties, which is very suitable for the cooling of metatitanic acid. After the graphite heat exchanger is used for a long time, there are many scale deposits on the inner wall of the heat exchanger, and most of them are organic substances. The traditional cleaning method is to use chemical cleaning and manual cleaning of the scale on the inner wall of the heat exchanger with iron wire. The cleaning difficulty is relatively large, and chemical cleaning causes certain corrosion to the equipment. Therefore, it is necessary to design a cleaning device for the tube wall of a graphite heat exchanger to solve this problem. Content of the Utility Model

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 3 , as an embodiment of the present invention, a cleaning device for the tube wall of a graphite heat exchanger 20 includes a support plate 1. A support table 19 is installed on the support plate 1. A chute is provided on the support plate 1. A mounting block 2 is slidably installed in the chute. A guiding groove is provided on the mounting block 2. A mounting plate 22 is slidably installed on the guiding groove. A connecting block 12 is installed on the side of the mounting plate 22 away from the mounting block 2. A guiding hole is provided on the connecting block 12. A bearing 11 is installed in the guiding hole;

[0023] A connecting pipe 10. The bearing 11 is sleeved on the connecting pipe 10. The connecting pipe 10 is rotatably connected to the connecting block 12 through the bearing 11. One end of the connecting pipe 10 is rotatably installed with a water inlet pipe 13, and the other end is fixedly installed with a mounting pipe 16. A nozzle 15 is installed on the mounting pipe 16. A suction pump 14 is installed on the water inlet pipe 13;

[0024] A telescopic member 3. One end of the telescopic member 3 is connected to the side wall of the chute, and the other end is connected to the mounting block 2;

[0025] A rotating assembly is installed on the mounting plate 22 and is connected to the connecting pipe 10;

[0026] A reciprocating assembly is installed on the mounting block 2. The reciprocating assembly intermittently contacts the mounting plate 22.

[0027] In this embodiment, when cleaning the tube wall of the heat exchanger 20, the heat exchanger 20 is placed on the support platform 19. The installed telescopic member 3 drives the connected mounting block 2 to move towards the side close to the support platform 19. The movement of the mounting block 2 to one side drives the nozzle 15 on the mounting pipe 16 to extend into the heat exchanger 20. Water from the water source connected to the water inlet pipe 13 is pumped by the suction pump 14 installed on the water inlet pipe 13 and sprayed out from the nozzle 15 on the mounting pipe 16, thereby cleaning the tube wall. During this process, the installed rotation assembly drives the connecting pipe 10 to rotate. The rotation of the connecting pipe 10 drives the mounting pipe 16 installed at one end to rotate, and the mounting pipe 16 drives the nozzle 15 to rotate. The rotation of the nozzle 15 can thus wash multiple positions on the tube wall of the heat exchanger 20, improving the cleaning efficiency. The reciprocating assembly drives the mounting plate 22 to reciprocate. In this way, the mounting plate 22 can drive the connecting pipe 10 on the connecting block 12 to reciprocate, and the connecting pipe 10 drives the nozzle 15 installed on the mounting pipe 16 to reciprocate within a small range, further improving the flushing efficiency.

[0028] Furthermore, the telescopic member 3 can be an electric telescopic rod or an electric push rod, etc., and no specific description is made here.

[0029] As an embodiment of the present invention, the rotation assembly includes a driving member 7. The driving member 7 is installed on the mounting plate 22, and a driving shaft 8 is installed at the output end of the driving member 7;

[0030] A connecting unit 9. One end of the connecting unit 9 is connected to the driving shaft 8, and the other end is connected to the connecting pipe 10.

[0031] In this embodiment, the driving member 7 drives the connected driving shaft 8 to rotate. The rotation of the driving shaft 8 drives the connecting pipe 10 connected thereto to rotate under the action of the connecting unit 9. The rotation of the connecting pipe 10 drives the mounting pipe 16 installed at one end to rotate, and the connecting pipe 10 drives the nozzle 15 to rotate. The rotation of the nozzle 15 can thus wash multiple positions on the tube wall of the heat exchanger 20, improving the cleaning efficiency.

[0032] Furthermore, the connecting unit 9 can be a gear set or a pulley set, etc., and no specific description is made here.

[0033] Furthermore, the driving member 7 can be a stepping motor or a servo motor, etc., and no specific description is made here.

[0034] As an embodiment of the present invention, the reciprocating assembly includes a driving component 4. The driving component 4 is installed on the mounting block 2, a driving rod 5 is installed at the output of the driving component 4, and a cam 6 is installed at the end of the driving rod 5 away from the driving component 4;

[0035] The elastic member 21 has one end connected to the guiding groove and the other end connected to the mounting plate 22.

[0036] In this embodiment, the driving member 4 drives the driving rod 5 connected thereto to rotate. The rotation of the driving rod 5 drives the cam 6 connected thereto to rotate. The rotation of the cam 6 contacts the mounting plate 22 and drives the mounting plate 22 to move to one side. When the mounting plate 22 moves to one side, the elastic member 21 will be compressed. When the cam 6 disengages from the mounting plate 22, under the action of the elastic member 21, the mounting plate 22 is driven to reset. In this way, the mounting plate 22 can drive the connecting pipe 10 on the connecting block 12 to reciprocate. The connecting pipe 10 drives the spray head 15 mounted on the mounting pipe 16 to reciprocate within a small range, and thus multiple positions on the tube wall of the heat exchanger 20 can be flushed.

[0037] Furthermore, the driving member 4 can be a stepping motor or a servo motor, etc., and no specific description is made here.

[0038] As an embodiment of the present utility model, it further includes a telescopic unit 17. The telescopic unit 17 is mounted on the mounting pipe 16, and a cleaning brush 18 is mounted at one end of the telescopic unit 17 away from the mounting pipe 16.

[0039] In this embodiment, the telescopic unit 17 is mounted on the mounting pipe 16, and a cleaning brush 18 is mounted at one end of the telescopic unit 17 away from the mounting pipe 16. The mounting pipe 16 extends into the tube of the heat exchanger 20. When the spray head 15 sprays and cleans the tube wall, the telescopic member 3 drives the cleaning brush 18 connected thereto to move towards one side of the tube wall, so that the cleaning brush 18 fits against the tube wall. Under the action of the connecting pipe 10 driving the mounting pipe 16 to rotate, the cleaning brush 18 rotates and cooperates with the flushing of the spray head 15 to scrape and clean the stains on the tube wall, further improving the cleaning quality.

[0040] Furthermore, the telescopic unit 17 can be an electric telescopic rod or an electric push rod, etc., and no specific description is made here.

[0041] As an embodiment of the present utility model, the elastic member 21 is a spring.

[0042] In this embodiment, the elastic member 21 is a spring. By providing a spring, during the rotation of the cam 6, the cooperation with the spring drives the mounting plate 22 to reciprocate. The reciprocating movement of the mounting plate 22 further drives the spray head 15 mounted on the mounting pipe 16 to reciprocate within a small range, and thus multiple positions on the tube wall of the heat exchanger 20 can be flushed. At the same time, the cleaning brush 18 is driven to reciprocate to clean the wall of the heat exchanger 20, improving the cleaning quality.

[0043] The working principle of the present utility model is as follows: When cleaning the tube wall of the heat exchanger 20, the heat exchanger 20 is placed on the support platform 19. The installed telescopic member 3 drives the connected mounting block 2 to move towards the side close to the support platform 19. The movement of the mounting block 2 to one side drives the nozzle 15 on the mounting pipe 16 to extend into the heat exchanger 20. Water at the water source connected to the water inlet pipe 13 is transported to the nozzle 15 on the mounting pipe 16 through the suction pump 14 installed on the water inlet pipe 13 and sprayed out, thereby cleaning the tube wall. During this process, the driving member 7 drives the connected driving shaft 8 to rotate. The rotation of the driving shaft 8 drives the connected connecting pipe 10 to rotate under the action of the connecting unit 9. The rotation of the connecting pipe 10 drives the mounting pipe 16 installed at one end to rotate. The connecting pipe 10 drives the nozzle 15 to rotate, and the rotation of the nozzle 15 can further wash multiple positions on the tube wall of the heat exchanger 20, improving the cleaning efficiency. The telescopic member 3 drives the connected cleaning brush 18 to move towards the tube wall side, making the cleaning brush 18 fit with the tube wall. Under the action of the connecting pipe 10 driving the mounting pipe 16 to rotate, the cleaning brush 18 rotates and cooperates with the washing of the nozzle 15 to scrape and clean the stains on the tube wall, further improving the cleaning quality. The driving component 4 drives the connected driving rod 5 to rotate. The rotation of the driving rod 5 drives the connected cam 6 to rotate. The rotation of the cam 6 contacts the mounting plate 22 and drives the mounting plate 22 to move to one side. When the cam 6 rotates away from the mounting plate 22, the mounting plate 22 is driven to reset under the action of the elastic member 21. In this way, the mounting plate 22 can drive the connecting pipe 10 on the connecting block 12 to reciprocate. The connecting pipe 10 drives the nozzle 15 installed on the mounting pipe 16 to reciprocate within a small range, thereby washing multiple positions on the tube wall of the heat exchanger 20.
