Description

Technical Field

[0001] The present invention relates to the technical field of noise reduction equipment, in particular to a novel vacuum pump noise reduction 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. Generally speaking, a vacuum pump is a device that uses various methods to improve, create, and maintain a vacuum in a closed space. Based on their operating principles, vacuum pumps can be broadly divided into two types: gas capture pumps and gas transfer pumps. These pumps are widely used in industries such as metallurgy, chemicals, food processing, and electronic coating.

[0003] At present, most of the new vacuum pump noise reduction devices on the market will generate loud noise when in use because the vacuum pump will generate violent vibrations during operation and there are no shock-absorbing measures. The noise generated by the vacuum pump mainly comes from the motor and pump body, and the decibel of the noise is very high, which can easily cause environmental pollution. On-site workers will suffer various irreversible damages to their bodies if they are affected by the noise for a long time. Summary of the Invention

[0004] The present invention aims to provide a novel vacuum pump noise reduction device to address the problem of excessive noise generated by vacuum pumps during operation, as discussed in the background art. To achieve this objective, the present invention provides the following technical solution: a novel vacuum pump noise reduction device comprising a pump body, the bottom of which is bolted to the top of a shock-absorbing assembly, the bottom of which is fixedly connected to the inner bottom wall of a liquid storage assembly, and a cooling assembly bolted to the front of the liquid storage assembly.

[0006] Preferably, the shock-absorbing assembly includes a support platform, a shock-absorbing rod, a shock-absorbing spring, a shock-absorbing tube, a fixed block, a deflection block and a movable roller. The pump body is fixedly installed on the top of the support platform by bolts, and the shock-absorbing rod is fixedly installed on the bottom at the center of the support platform. The bottom end of the shock-absorbing rod is fixedly connected to one end of the shock-absorbing spring, and the bottom end of the shock-absorbing spring is fixedly connected to the inner bottom wall of the shock-absorbing tube, and the bottom end of the shock-absorbing tube is fixedly connected to the inner bottom wall of the liquid storage assembly.

The support platform can drive the shock absorber rod to move up and down when it moves up and down. The shock absorber rod can compress the shock absorber spring when it moves up and down. When the shock absorber rod moves telescopically in the shock absorber tube, the up and down movement of the support platform drives the fixed block to move up and down. The downward movement of the fixed block can press the deflection block to generate a deflection force with the fixed block as the axis. When the deflection block is deflected, it can drive the movable roller to roll on the inner bottom wall of the liquid storage tank, thereby reducing the vibration force on the support platform.

[0008] Preferably, the liquid storage component includes a liquid storage tank, a socket, a return pipe and a first sealing tube, the inner bottom wall at the center of the liquid storage tank is fixedly connected to the bottom end of the shock-absorbing tube, and the inner bottom wall of the liquid storage tank near both sides is rollingly connected to the outer wall of the movable roller, the outer walls on both sides of the liquid storage tank are fixedly connected with the socket, and the inner side wall of the liquid storage tank near the back is fixedly connected to one end of the return pipe, the other end of the return pipe is fixedly installed with a first sealing tube, and a noise reduction component is plugged into the interior of the first sealing tube, the inner side wall of the liquid storage tank near the front is fixedly connected to one end of the cooling component, the support platform moves downward in the liquid storage tank, and the coolant in the liquid storage tank will give the support platform a reverse supporting force, and combined with the friction between the shock-absorbing rod and the inner wall of the shock-absorbing tube, it can avoid repeated movement of the shock-absorbing spring, and further reduce the vibration generated by the pump body.

[0009] Preferably, there are two sockets, and both sockets are provided with socket holes, into which the noise reduction component can be accurately inserted, so that the noise reduction component and the liquid storage component form a closed space.

[0010] Preferably, the cooling assembly comprises a micro water pump, a mounting block, an inlet pipe, an outlet pipe and a second sealing pipe, the outer wall of the micro water pump is clamped and connected with the inner wall of the mounting block, the back of the mounting block is fixedly installed on the front of the liquid storage bin through bolts, the input end of the micro water pump is fixedly connected with one end of the inlet pipe, the other end of the inlet pipe is fixedly connected with the inner side wall close to the front of the liquid storage bin, the output end of the micro water pump is fixedly connected with one end of the outlet pipe, and the other end of the outlet pipe is provided with the second sealing pipe, the inner wall of the second sealing pipe is movably inserted with the noise reduction assembly, and the mounting block can clamp the micro water pump to reduce the vibration generated by the micro water pump, at the same time, the micro water pump can inject the cooling liquid in the liquid storage bin into the outlet pipe through the inlet pipe, and finally into the noise reduction assembly through the second sealing tank.

[0011] Preferably, the noise reduction assembly comprises a connecting pipe, a sealing cover, an insertion block, an insertion pipe and sound-absorbing cotton, the outer wall of the bottom end of the connecting pipe is movably inserted with the inner wall of the second sealing pipe, the other end of the connecting pipe is fixedly connected with the front of the sealing cover, the outer walls on both sides of the sealing cover are fixedly connected with the insertion blocks, the bottom of the insertion block is provided with an insertion rod inserted with the insertion hole, the inner wall of the top of the sealing cover is provided with an output hole for inserting the output end of the pump body, the top of the sealing cover is fixedly provided with the insertion pipe, the other end of the insertion pipe is movably inserted with the inner wall of the first sealing pipe, and the inner top wall of the sealing cover is provided with the sound-absorbing cotton, the bottom of the sealing cover is movably abutted with the top of the liquid storage bin, and a sealing rubber strip is arranged at the connection between the sealing cover and the liquid storage bin, the sealing rubber strip can improve the airtightness between the sealing cover and the liquid storage bin, most of the noise generated by the pump body is absorbed by the sound-absorbing cotton, the sound-absorbing cotton converts the noise into heat energy through vibration after absorbing the noise, the sealing cover can cool the sound-absorbing cotton, and the cooling liquid in the liquid storage bin and the cooling liquid in the cooling cavity of the sealing cover can wrap the pump body in a closed space, and since the sound transmission frequencies of solid and liquid are different, the noise generated by the pump body will be frequency-shifted in the closed space, so as to further reduce the noise generated by the pump body.

[0012] Preferably, the inside of the sealing cover is provided with a cooling cavity, and the cooling cavity is communicated with the connecting pipe and the insertion pipe, the micro water pump is started, and the cooling liquid in the liquid storage bin is conducted into the cooling cavity of the sealing cover, so that the cooling liquid in the liquid storage bin can circulate.

[0013] Compared with the prior art, the present application has the following advantages:

[0014] In the present invention, most of the noise generated by the pump body is absorbed by the sound-absorbing cotton, and the sound-absorbing cotton absorbs the noise through vibration and converts it into heat energy. The micro water pump is started, and the micro water pump conducts the coolant in the liquid storage tank to the cooling cavity of the sealing cover. The sealing cover can cool the sound-absorbing cotton. At the same time, the coolant in the liquid storage tank and the coolant in the cooling cavity of the sealing cover can wrap the pump body in a closed space. Since the sound transmission frequencies of solids and liquids are different, the noise generated by the pump body will produce a frequency error in the closed space, thereby further reducing the noise generated by the pump body, thereby avoiding the environmental pollution caused by the loud noise generated by the vacuum pump, so that on-site workers are not affected by the noise, and the health of the workers is guaranteed.

[0015] When the pump is started, the pump body will generate violent vibrations. Since the pump body is fixedly mounted on the support platform, the vibration force generated by the pump body will drive the support platform to move up and down. When the support platform moves up and down, it can drive the shock-absorbing rod to move up and down. The shock-absorbing rod can compress the shock-absorbing spring when it moves up and down. When the shock-absorbing rod is telescopically moved in the shock-absorbing tube, the support platform moves up and down, driving the fixed block to move up and down. The downward movement of the fixed block can press the deflection block with the fixed block as the axis to generate a deflection force. When the deflection block is deflected, it can drive the moving roller to roll on the inner bottom wall of the liquid storage tank, thereby reducing the vibration force exerted on the support platform. At the same time, the support platform moves downward in the liquid storage tank, and the coolant in the liquid storage tank will give the support platform a reverse supporting force. At the same time, combined with the friction force between the shock-absorbing rod and the inner wall of the shock-absorbing tube, the shock-absorbing spring can be avoided from moving repeatedly, further reducing the vibration generated by the pump body, thereby reducing the noise generated by the vibration of the pump body.
