Description

Technical Field

[0001] This application relates to the technical field of vacuum pump cooling devices, and in particular to a vacuum pump cooling device for asphalt production. Background Technology

[0002] In the asphalt production process, vacuum pumps need to operate for extended periods and withstand high temperatures and pressures. This can cause the internal temperature of the vacuum pump to rise, affecting its efficiency and stability. Therefore, effective cooling measures are necessary to ensure the normal operation of the vacuum pump. A vacuum pump is a device used to create and maintain a vacuum environment; its working principle is primarily based on the process of gas compression and emission. Specifically, a vacuum pump uses a mechanical structure to extract gas from a sealed container, thereby reducing the gas pressure inside the container and creating a vacuum environment. In the asphalt production process, vacuum pumps are mainly used to remove gases and vapors generated during production to maintain the stability and efficiency of the process.

[0003] A search revealed Chinese Patent Publication No. CN214617217U, which discloses a vacuum pump cooling device for high-grade road asphalt production. The device includes a vacuum pump with an inlet pipe and an outlet pipe. A filter is installed on the inlet pipe. A cooling coil is coiled around the inner wall of the outlet pipe, connected to both an inlet and outlet pipe. A cooling jacket is installed on the outer wall of the outlet pipe, connected to both an inlet and outlet pipe. Both the outlet pipe and the outlet pipe are connected to a water pump, which is sequentially connected to a heat exchanger, a cooler, a cooling water tank, and a water supply pump. The water supply pump is connected to both the inlet pipe and the inlet pipe. A one-way valve is installed on the outlet pipe.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Although the cooling coil installed on the inner wall of the exhaust pipe and the cooling jacket installed on the outer wall in this patent can dissipate heat from the exhaust pipe, the installation method is too complicated, and the repair and replacement are very troublesome when the cooling jacket and cooling coil fail.

[0005] Therefore, in response to the above problems, the applicant provides a vacuum pump cooling device for asphalt production. Utility Model Content

[0006] In order to solve the problems mentioned in the background art, this application provides a vacuum pump cooling device for asphalt production.

[0008] A vacuum pump cooling device for asphalt production includes a vacuum pump, a clamp, and an exhaust pipe. Multiple heat dissipation fins are laid on the outer circumference of the exhaust pipe. An exhaust pipe 1 and an exhaust pipe 2 are respectively clamped on the heat dissipation fins. A fan is installed at the bottom end of the exhaust pipe 2. A clamp is installed on the heat dissipation fins.

[0017] 2.

Detailed implementation manners

[0024] The following is a further detailed description of the present application in conjunction with the attached Figure 1-5 drawings.

[0025] The embodiment of the present application discloses a vacuum pump cooling device for asphalt production.

[0026] As Figure 1-5 shown, a vacuum pump cooling device for asphalt production includes a vacuum pump 1, a clamp 7, and an exhaust pipe 10. A plurality of heat dissipation fins 6 are laid on the circumferential outer wall of the exhaust pipe 10. The first exhaust pipe 3 and the second exhaust pipe 5 are respectively clamped on the heat dissipation fins 6. A fan 2 is installed at the bottom end of the second exhaust pipe 5. A clamp 7 is installed on the heat dissipation fins 6.

[0027] Please refer to Figure 1 and Figure 4 , the vacuum pump 1 includes a pump body, an intake pipe, and an exhaust pipe 10. A plurality of limit blocks 100 are fixedly connected to the circumferential outer wall of the exhaust pipe 10 in an annular array. The heat dissipation fins 6 are composed of a plurality of connecting blocks 60, a heat collection end 61, and a heat dissipation end 62. A plurality of slots 610 are opened at the bottom ends of the plurality of heat collection ends 61. The slots 610 are inserted into the limit blocks 100. An arc-shaped groove adapted to the limit block 100 is opened at one end of the plurality of heat collection ends 61. In order to quickly clamp the heat collection end 61 on the limit block 100, serial numbers are correspondingly marked on both the plurality of heat collection ends 61 and the plurality of limit blocks 100. For example, the limit block 100 engraved with the word "one" corresponds to the heat collection end 61 engraved with the word "one", so that it is convenient for users to quickly install the heat collection end 61 on the limit block 100.

[0028] Please refer to Figure 1 and Figure 3, on the top surfaces of multiple heat collection ends 61, four heat dissipation ends 62 are fixedly connected. A clamp 7 is installed on the surface of the heat collection end 61, and the clamp 7 is located between two adjacent heat dissipation ends 62. In order to make the heat dissipation fins 6 fit more closely to the outer wall of the exhaust pipe 10 to absorb heat, the heat dissipation fins 6 are locked to the outer surface of the exhaust pipe 10 through the clamp 7. At the same time, the heat dissipation fins 6 are closely fitted to the outer wall surface of the exhaust pipe 10 through the clamp 7, greatly increasing the surface area of heat exchange. When the heat source medium flows through the inside of the exhaust pipe 10, the heat is transferred from the pipe wall of the exhaust pipe 10 to the connecting block 60, and the connecting block 60 quickly dissipates the heat to the surrounding air through the heat collection end 61 with a larger surface area, forming a strong convection effect.

[0029] Please refer to Figure 3 , on one end of the exhaust pipe one 3 and the exhaust pipe two 5, an arc-shaped groove one 30 and an arc-shaped groove two 50 are respectively opened. The arc-shaped groove one 30 and the arc-shaped groove two 50 are clamped on the connecting block 60. The air outlet of the fan 2 is equipped with the arc-shaped groove two 50, and the fan 2 is externally connected to a power source. The arc-shaped groove one 30 and the arc-shaped groove two 50 are clamped on the ring formed by multiple connecting blocks 60. At the same time, the heat dissipation end 62 is wrapped in the cavity formed by the exhaust pipe one 3 and the exhaust pipe two 5. When the heat in the exhaust pipe 10 is transmitted out through the heat dissipation end 62, it is discharged through the exhaust pipe one 3 by the fan 2.

[0030] Please refer to Figure 3 , the orthographic projection of the combination of the exhaust pipe one 3 and the exhaust pipe two 5 in the horizontal direction is in an "L" shape. A frame one 31 is fixedly connected to the exhaust pipe one 3, and a frame two 51 is fixedly connected to the exhaust pipe two 5. A plurality of bolts 4 are commonly threadedly connected to the frame one 31 and the frame two 51. In order to make the exhaust pipe one 3 and the exhaust pipe two 5 fit better on the exhaust pipe 10, the connection of the exhaust pipe one 3 and the exhaust pipe two 5 is locked through the bolts 4.

[0031] The implementation principle of the asphalt production vacuum pump cooling device in the embodiment of the present application is as follows:

[0032] One end of multiple heat collection ends 61 is provided with an arc adapted to the limiting block 100. In order to quickly install the heat collection end 61 on the limiting block 100, both multiple heat collection ends 61 and multiple limiting blocks 100 are correspondingly marked with serial numbers. For example, the limiting block 100 engraved with the word "one" corresponds to the heat collection end 61 engraved with the word "one", which facilitates the user to quickly install the heat collection end 61 on the limiting block 100. The heat dissipation fins 6 are closely fitted to the outer wall surface of the exhaust pipe 10 through the clamp 7, greatly increasing the surface area of heat exchange. When the heat passes through the surface of the exhaust pipe 10, it will be adsorbed by the connecting block 60 and dissipated from the heat collection end 61. Compared with the traditional installation method of installing cooling coils and cooling jackets on the inner wall of the exhaust pipe 10, which is complex, the heat dissipation fins 6 are locked through the clamp 7, making their installation and disassembly faster, which is convenient for the maintenance and repair of the heat dissipation fins 6;

[0033] When the heat source medium flows through the interior of the exhaust pipe 10, the heat is transferred to the connecting block 60 through the pipe wall of the exhaust pipe 10. The connecting block 60 then quickly dissipates the heat into the surrounding air through the heat collection end 61 with a large surface area. At this time, the heat is concentrated in the cavity formed by the second exhaust pipe 5 and the first exhaust pipe 3. Turning on the fan 2 allows the heat to be used for power generation and preheating recovery through the first exhaust pipe 3, avoiding the waste caused by the heat generated by the heat dissipation fins 6 flowing into the air.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
