Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pumps, in particular to a vacuum pump with a cooling device. Background Art

[0002] A vacuum pump is a device or equipment that creates a vacuum by evacuating a container using mechanical, physical, chemical, or physicochemical methods. Vacuum pumps are primarily categorized by their operating principle: gas delivery pumps and gas capture pumps. Gas delivery pumps continuously draw in and out gas to achieve the desired vacuum, while gas capture pumps reduce the amount of gas in a container by adsorbing or condensing gas molecules.

[0003] During the use of the vacuum pump, the temperature inside the equipment gradually increases because it remains in operation for a long time. The existing devices for cooling the vacuum pump include water-cooling devices or air-cooling devices, but the existing cooling devices cannot fit well to the outer wall of the vacuum pump. Poor fitting will lead to a reduction in the contact area between the cooling medium and the outer wall of the vacuum pump, which can easily reduce the heat exchange efficiency.

[0007] One end of the cooling pressure block on the side of the upper fastening assembly of the clamping arc block is connected to the first conveying pipe, and one end of the cooling pressure block on the side of the lower fastening assembly of the clamping arc block is connected to the second conveying pipe. Transition hoses are connected in sequence between adjacent cooling pressure blocks, and cooling cavities are opened through the cooling pressure blocks.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4A vacuum pump with a cooling device includes a vacuum pump body 1, two groups of cooling components 2 are symmetrically arranged on both sides of the outer wall of the vacuum pump body 1, and the upper and lower parts of the two groups of cooling components 2 are spliced ​​and fixed by multiple fastening components 3. The cooling component 2 includes a clamping arc block 21, and the clamping arc block 21 has multiple cavities at equal distances therefrom. A limiting slider 28 is slidably arranged in the cavity. The limiting slider 28 passes through the clamping arc block 21 on the side of the splicing surface and is connected to a cooling pressing block 25. In addition, multiple springs 27 are equidistantly arranged on one side of the cooling pressing block 25 in the cavity.

[0022] In addition, one end of the cooling pressure block 25 on the side of the upper fastening component 3 of the clamping arc block 21 is connected to the first conveying pipe 29, and one end of the cooling pressure block 25 on the side of the lower fastening component 3 of the clamping arc block 21 is connected to the second conveying pipe 23. Transition hoses 26 are connected in sequence between adjacent cooling pressure blocks 25, and cooling cavities are opened through the cooling pressure blocks 25.

[0023] At the same time, a cooling water tank 22 is provided on the side of the clamping arc block 21 away from the splicing surface, and a fixing block is provided on one side of the cooling water tank 22. A cavity is opened in the fixing block, and a water pump body 24 is placed in the cavity.

[0024] Furthermore, the suction end of the water pump body 24 is inserted into the cooling water tank 22 , and the output end of the water pump body 24 is connected to the first delivery pipe 29 .

[0025] At the same time, the fastening assembly includes a fastening bolt and a fastening nut, and the fastening bolt is threadedly connected to the fastening nut. It is worth noting that the specific structure of the fastening bolt, the fastening nut, the vacuum pump body 1 and their working mode are all existing technologies currently disclosed on the market, and do not belong to the main technical problems that need to be solved in this technical solution. Therefore, they are not elaborated in this utility model.

[0026] In addition, the other end of the second delivery pipe 23 is connected to the cooling water tank 22, and a reflux hole is opened in the cooling water tank 22 at the second delivery pipe 23. It is worth noting that coolant is stored in the cooling water tank 22, and a feed through hole is opened on one side of the cooling water tank 22, and a sealing plug is stuck at the feed through hole on one side of the cooling water tank 22.

[0027] In addition, one side of the second conveying pipe 23 and the first conveying pipe 29 are both fixedly connected to the clamping arc block 21 .

[0028] In this embodiment, two symmetrically arranged cooling components 2 are coordinated with the fastening component 3 to ensure that the cooling pressure block 25 is better fitted to the outer wall of the vacuum pump body 1, thereby increasing the contact area between the cooling medium and the outer wall of the vacuum pump, and facilitating the absorption of the heat generated during the operation of the vacuum pump body 1, thereby achieving cooling treatment of the vacuum pump body 1.

[0029] Among them, when the clamping arc block 21 gradually moves toward the outer wall of the vacuum pump body 1, its cooling pressure block 25 gradually fits toward the outer wall of the vacuum pump body 1, and under the action of the spring 27, it can ensure that the cooling pressure block 25 is better fitted to the outer wall of the vacuum pump body 1, and then the coolant in the cooling water tank 22 is moved to the cooling pressure block 25 through the water pump body 24, and finally returned to the cooling water tank 22 through the second delivery pipe 23, thereby absorbing the heat generated during the operation of the vacuum pump body 1, thereby achieving cooling treatment of the vacuum pump body 1.

[0030] In the present invention, two symmetrically arranged cooling components 2 are coordinated with the fastening component 3 to ensure that the cooling pressure block 25 is better fitted to the outer wall of the vacuum pump body 1, thereby increasing the contact area between the cooling medium and the outer wall of the vacuum pump, and facilitating the absorption of the heat generated during the operation of the vacuum pump body 1, thereby achieving cooling treatment of the vacuum pump body 1.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
