[0014] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the attached drawings and preferred embodiments, details the specific implementation manner, structure, features and their effects of the present utility model as follows.

[0015] Embodiment: Please refer to Figures 1-3 , a mechanical seal, comprising a mechanical seal body 1 and a cooling mechanism 2. The cooling mechanism 2 includes a sleeve 201, a water inlet pipe 202 and a water outlet pipe 203. The water inlet pipe 202 is connected to a water pump. One end of the sleeve 201 is connected to the bottom of the vacuum emulsifying machine 8, and the other end of the sleeve 201 is connected to the motor 9. The output shaft of the motor 9 penetrates the bottom of the vacuum emulsifying machine 8. The mechanical seal body 1 seals the connection between the output shaft of the motor 9 and the vacuum emulsifying machine 8. Both the water inlet pipe 202 and the water outlet pipe 203 are connected to the sleeve 201. The mechanical seal body 1 is arranged inside the sleeve 201. The mechanical seal body 1 exchanges heat inside the sleeve 201. By means of a water pump, water is introduced into the sleeve 201, and the water inside the sleeve 201 can quickly cool the mechanical seal body 1, reducing the influence of high temperature on the mechanical seal body 1.

[0016] In an alternative embodiment, a baffle 3 is provided inside the sleeve 201. The bottom of the baffle 3 is sealed, and the top of the baffle 3 is open. The water outlet end of the water inlet pipe 202 penetrates through the side wall of the baffle 3 and communicates with the baffle 3. The mechanical seal body 1 is arranged inside the baffle 3. Water directly flows into the inside of the baffle 3 from the water inlet pipe 202. When the water level reaches the top of the baffle 3, it then flows into the sleeve 201 from the opening of the baffle 3 and then flows out from the water outlet pipe 203. Since the mechanical seal body 1 is arranged inside the baffle 3 and the pipe orifice of the water outlet pipe 203 is arranged below the seal, that is to say, the liquid level of the water is lifted by the baffle, so that the mechanical seal body 1 is immersed in water, further improving the cooling effect of the mechanical seal body 1.

[0017] In an alternative embodiment, the bottom of the baffle 3 is sealingly connected to the output shaft of the motor 9 through a waterproof shaft seal assembly 4. The baffle 3 and the output shaft of the motor 9 are sealed through the waterproof shaft seal assembly 4 to prevent water from flowing into the motor 9. Among them, the waterproof shaft seal assembly 4 is a prior art and will not be elaborated here.

[0018] In an alternative embodiment, the length of the baffle 3 is 2 / 3 of the length of the sleeve 201. The bottom of the baffle 3 is sealingly connected to the inner wall of the sleeve 201 through a sealing ring 5. That is to say, the sealing ring 5 separates the sleeve 201 into a wet area and a dry area. The waterproof shaft seal assembly 4 is located in the dry area inside the sleeve 201. A heat dissipation hole 6 is provided on the side wall at the bottom of the sleeve 201, and the heat dissipation hole 6 is located below the baffle 3. The heat dissipation hole 6 can further dissipate heat from the sleeve 201 and can also dissipate heat from the waterproof shaft seal assembly 4.

[0019] Both the water inlet pipe 202 and the water outlet pipe 203 are connected to the sleeve 201 through quick connectors 7. The quick connectors 7 can achieve the quick assembly of the water inlet pipe 202 and the water outlet pipe 203. Among them, the quick connectors 7 are a prior art and will not be elaborated here.

[0020] The working principle of this embodiment: When in use, water is pumped into the inside of the baffle 3 from the water inlet pipe 202 by a water pump. When the water level reaches the top of the baffle 3, it then flows into the sleeve 201 from the opening of the baffle 3. After the water level between the sleeve 201 and the baffle 3 reaches the pipe orifice of the water outlet pipe 203, it then flows out from the water outlet pipe 203. Among them, the mechanical seal body 1 is arranged inside the baffle 3. That is to say, the mechanical seal body 1 is immersed in water, and the mechanical seal body 1 can be quickly cooled in water. Therefore, this utility model has a good heat dissipation effect and reduces the influence of temperature on the performance of the mechanical seal body 1.

[0021] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present utility model by using the above-disclosed technical content.
