Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of dustproof and noise reduction devices, and in particular to a dustproof and noise reduction device for an oil pump. Background Technology
[0002] Dust and noise reduction devices for oil pumps are mainly used in industries such as petroleum, chemical, and energy. They are used to reduce the noise generated by the oil pump during operation and prevent external dust and other impurities from entering the equipment, thereby improving the working efficiency of the equipment and extending its service life. Therefore, it is necessary to design a dust and noise reduction device for oil pumps.
[0003] Most existing oil pumps use dust covers on the outside to prevent dust from entering. However, this method fails to filter out impurities and dust from the pumped oil. Adding a sealing device at the inlet connection point prevents dust from entering. If dust and impurities do enter, it will cause wear on internal parts, reducing equipment efficiency and lifespan. During operation, existing oil pumps generate varying degrees of noise due to liquid flow, internal mechanical operation, and vibrations between the pump body and pipelines. This noise not only affects operators and the surrounding environment, but long-term exposure may also harm the health of workers. Therefore, noise reduction devices need to be installed on oil pumps. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] The purpose of this utility model is to provide a dustproof and noise reduction device for oil pumps, which solves the problem mentioned in the background art. Most existing oil pumps use dust covers on the outside to prevent dust from entering. However, this method lacks the ability to filter out impurities and dust in the pumped oil. Adding a sealing device at the inlet connecting pipe prevents dust from entering. If dust and impurities enter, it will cause wear on internal parts, reducing equipment efficiency and service life. During operation, existing oil pumps generate varying degrees of noise due to liquid flow, internal mechanical operation, and vibration of the pump body and pipeline. This noise not only affects operators and the surrounding environment, but long-term noise exposure may also harm the health of workers. Therefore, it is necessary to install a noise reduction device on the oil pump.

The noise reduction mechanism includes a soundproof cover fixedly connected to the top surface of the base, and sound-absorbing cotton installed inside the soundproof cover.
[0008] As a further embodiment of this utility model, the top surface of the soundproof cover is provided with a heat dissipation window, and a dustproof net is installed inside the heat dissipation window. The dustproof net serves to dissipate heat while preventing dust from entering.
[0009] As a further embodiment of this utility model, the top surface of the soundproof cover is fixedly connected to the four corners of the top surface with top columns, and the top of the top columns is fixedly connected to the cover plate. The cover plate serves to block external dust and rainwater from entering.
[0010] As a further embodiment of this utility model, the left hinge of the soundproof cover is connected to a door, and a handle is fixedly connected to the upper surface of the door. The door facilitates opening, displaying the internal devices, and performing maintenance.

[0014] (III) Beneficial Effects
[0015] This utility model provides a dustproof and noise reduction device for an oil pump, which has the following beneficial effects:
[0016] 1. This oil pump uses a dustproof and noise reduction device. Through the setting of the dust removal mechanism, when the device is to pump oil, first, the external pipe is put on the outside of the casing. After that, the sealing ring is put on the outside of the external pipe, so that the sealing gasket is tightly attached to the external pipe to prevent gaps. Then, tighten the fixing bolt inside the fixing plate above the sealing ring to fix the external pipe. Then, the oil pumping begins. The oil flows through the adapter to the Y-shaped filter. The filter barrel inside the Y-shaped filter removes impurities and dust from the oil, which prevents dust from entering and avoids the entry of dust and impurities, which would cause wear on internal parts and reduce the efficiency and service life of the equipment.
[0017] 2. This oil pump uses a dustproof and noise reduction device. The noise reduction mechanism addresses the noise generated during oil pumping due to vibration. A soundproof cover is installed around the pump to block some noise. Furthermore, sound-absorbing cotton (made of rock wool) is installed inside the cover to absorb additional noise. Damping shock absorbers and mounting brackets are also installed on the outside and bottom of the pump to ensure stability and prevent noise generation. This noise reduction effectively mitigates the impact of noise on operators and the surrounding environment, and prevents long-term noise exposure from harming workers' health.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution for a dustproof and noise reduction device for an oil pump: The device includes an oil pump 1, a pump head 2 mounted on the right side of the pump 1, an oil inlet on the right side of the pump head 2, a dust removal mechanism 3 mounted outside the oil inlet, a base 4 fixedly connected to the bottom of the oil pump 1, and a noise reduction mechanism 5 fixedly connected to the top surface of the base 4. The dust removal mechanism 3 includes a Y-shaped filter 301 mounted outside the oil inlet 2, an adapter 302 threadedly connected to the right side of the Y-shaped filter 301, a sleeve 303 fixedly connected to the right side of the adapter 302, and a sealing ring 304 fitted onto the outside of the sleeve 303. The noise reduction mechanism 5 includes a soundproof cover 501 fixedly connected to the top surface of the base 4, and sound-absorbing cotton 502 installed inside the soundproof cover 501.
[0025] Please see Figure 3 The top surface of the soundproof cover 501 is provided with a heat dissipation window, and a dustproof net 6 is installed inside the heat dissipation window. The dustproof net 6 serves to dissipate heat while preventing dust from entering.
[0026] Please see Figure 3 The top of the soundproof cover 501 is fixedly connected to the four corners of the top surface with top posts 7, and the top of the top posts 7 is fixedly connected to the cover plate 8. The cover plate 8 serves to block external dust and rainwater from entering.
[0027] Please see Figure 3 The left hinge of the soundproof cover 501 is connected to the door 9, and a handle 10 is fixedly connected to the upper surface of the door 9. The door 9 is designed to facilitate opening, displaying the internal devices, and performing maintenance.
[0028] Please see Figure 2 The Y-shaped filter 301 is fixedly connected to a filter tank 11 on the left side. The filter tank 11 is equipped with a filter barrel 12. The filter barrel 12 is designed to filter out impurities and dust in the oil.
[0029] Please see Figure 2 A sealing gasket 13 is installed inside the sealing ring 304. A fixing piece 14 is fixedly connected to the top surface of the sealing ring 304. A fixing bolt 15 is threaded inside the fixing piece 14. The sealing gasket 13 is used to tighten the external pipe to prevent leakage.
[0030] Please see Figure 4Damping shock absorbers 17 are fixedly connected to the bottom surface of the base 4 around the perimeter. Fixing brackets 16 are fixedly connected to the left and right sides of the base 4. The fixing brackets 16 are used to fix the equipment and reduce vibration, thereby indirectly reducing noise.
[0031] In this invention, the working steps of the device are as follows:
[0032] First step: When the device is to transport oil, first put the external pipe on the outside of the sleeve 303. After putting it on, put the sealing ring 304 on the outside of the external pipe, so that the sealing gasket 13 is tightly attached to the external pipe to prevent gaps. Then tighten the fixing bolt 15 inside the fixing piece 14 above the sealing ring 304 to fix the external pipe. Then start transporting oil.
