Description

Technical Field

[0001] The utility model relates to the technical field of mechanical seal protection, in particular to a mechanical seal circulation cooling device. Background Art

[0002] The mechanical seal is an inherent structure of the pump body. The mechanical seal will generate heat during operation, causing the temperature of the mechanical seal to rise. In order to ensure that the pump can operate stably for a long time, the mechanical seal needs to be cooled. At this time, a cooling device is needed.

[0003] For example, patent 201721861922.7 discloses a mechanical seal cooling device, belonging to the field of chemical equipment. It includes a pump seal, a seal water inlet pipe, and a seal water outlet pipe, and is characterized by: a water tank, the seal water inlet pipe and the seal water outlet pipe respectively connecting the seal and the water tank, the water tank containing cooling water, and the seal positioned below the liquid level in the water tank.

[0004] During the use of the above-mentioned cooling device, after the cooling water has cooled the mechanical seal, the water that has absorbed heat will flow back to the water tank again to wait for the next mechanical seal cooling. Although this method can achieve a weak natural water uninterrupted circulation cooling, the combination of cold water and water that has absorbed heat will inevitably lead to uneven hot and cold of the cooling water in the water tank, thereby failing to achieve a good mechanical seal cooling effect. Therefore, the present application provides a mechanical seal circulation cooling device to meet the needs. Utility Model Content

[0018] In the above scheme, by setting up a circulating cooling mechanism, the staff opens the float valve in advance so that external cooling water can enter the water tank through the water inlet pipe. When the mechanical seal is working, the staff starts the water pump.

Combined with the ventilation of the ventilation and heat dissipation nets set above and on both sides of the assembly box, the water that absorbs the heat in the heat dissipation pipe can be effectively cooled and dissipated. The arranged heat dissipation pipe can effectively increase the heat dissipation area and provide a certain efficiency for heat dissipation. After heat dissipation is completed, it will return to the water tank along the heat dissipation pipe, thereby achieving the purpose of circulating cooling.

[0019] By setting up a cleaning mechanism, before changing the water in the water tank, the personnel can open the drain valve to discharge the internal sewage. During this process, the personnel can synchronously start the second motor to rotate the transmission screw. At this time, the screw sleeve that acts on the screw will carry the scraper frame and cooperate with the guide sleeve and guide rod to scrape along the inner wall of the water tank to avoid impurities from remaining in the water tank and provide a better environment for the next cooling water filling.

[0020] By setting up a dust-proof mechanism, the dust cover is mainly used to provide a better dust-proof effect for the water tank, and the existence of the first sealing gasket and the second sealing gasket is to increase the fit between the two and reduce the entry of external impurities. Personnel can open the dust cover appropriately to observe the condition of the internal water to decide whether to change the water. BRIEF DESCRIPTION OF THE DRAWINGS

Before changing the water in the water tank 2, the personnel can open the drain valve 8 to discharge the internal sewage. During this process, the personnel can synchronously start the second motor 63 to rotate the transmission screw 62. At this time, the screw sleeve 64 that acts on the screw will carry the scraping frame 65 to cooperate with the guide sleeve 66 and the guide rod 67 to perform scraping operations along the inner wall of the water tank 2, so as to avoid impurities from remaining in the water tank 2 and provide a better environment for the next cooling water filling.

Personnel can open the dustproof cover 72 appropriately to observe the internal water condition to decide whether to change the water.

[0037] The working principle of the technical solution provided by this utility model is as follows:

[0038] The staff opens the float valve 4 in advance so that external cooling water can enter the water tank 2 through the water inlet pipe 3. When the mechanical seal 514 is working, the staff starts the water pump 511. Under the guidance of the first connecting pipe 512 and the second connecting pipe 513, the cooling water in the water tank 2 can flow into and pass through the mechanical seal 514 to cool it down, and then be discharged to the heat dissipation pipe 516 along the third connecting pipe 515. Since this part of the cooling water absorbs the heat from the mechanical seal 514, the staff can start the first motor 533 inside the assembly box 52 to rotate the transmission rod 534. At this time, under the meshing transmission of two synchronous wheels 536 and a synchronous belt 537, the fans 538 at the respective ends of the transmission rod 534 and the rotating rod 535 can be synchronized to operate, and the ventilation of the ventilation and heat dissipation nets 539 arranged above and on both sides of the assembly box 52 can be effectively cooled and dissipated. The heat dissipation pipe 516 can effectively increase the heat dissipation area and provide a certain degree of heat dissipation efficiency. After the heat dissipation is completed, it will flow back to the water tank 2 along the heat dissipation pipe 516, thereby achieving the purpose of circulating cooling. Secondly, the dust cover 72 is mainly used to provide a better dust-proof effect for the water tank 2, and the existence of the first sealing gasket 74 and the second sealing gasket 75 is to increase the fit between the two and reduce the entry of external impurities. Personnel can open the dust cover 72 appropriately to observe the internal water condition to decide whether to change the water. Finally, before changing the water in the water tank 2, personnel can open the drain valve 8 to discharge the internal sewage. During this process, personnel can synchronously start the second motor 63 to rotate the transmission screw 62. At this time, the screw sleeve 64 acting with the screw will carry the scraper frame 65 to cooperate with the guide sleeve 66 and the guide rod 67 to scrape along the inner wall of the water tank 2 to avoid impurities from remaining in the water tank 2 and provide a better environment for the next cooling water filling.
