Description

Technical Field

[0001] This utility model relates to the field of compressor noise reduction technology, specifically a compressor noise reduction housing mechanism. Background Technology

[0002] A compressor is a power device that increases gas pressure through mechanical motion. Its core function is to convert mechanical energy into the pressure energy and kinetic energy of gas. It is widely used in refrigeration and air conditioning, petrochemicals, energy transmission and other fields, and is a core thermodynamic device in modern industry. When it is working, it is prone to noise due to gas pulses and mechanical vibrations, so a noise reduction housing mechanism is needed to reduce the noise of the compressor during operation and improve the quietness of the environment.

[0003] According to the scroll compressor noise reduction mechanism disclosed in Chinese Patent Publication No. CN222894376U, it includes a scroll compressor body, a noise reduction mechanism fixed on the surface of the scroll compressor body, the noise reduction mechanism including a first fixing block, a second fixing block fixed on the surface of the first fixing block, a first sound insulation cotton provided on the surface of the first fixing block, a third fixing block fixed inside the first sound insulation cotton, and a second sound insulation cotton provided on the surface of the scroll compressor body.

[0004] However, the compressor noise reduction housing mechanism of the above-mentioned device still has the following shortcomings: the sound insulation cotton is simply fixed by the fixing block or directly stuffed into the housing. Under the long-term high-frequency vibration of the compressor, the sound insulation cotton is prone to loosening and displacement, resulting in sound insulation gaps, noise leakage, and a gradual decline in noise reduction performance.

[0005] Therefore, we propose a compressor noise reduction housing mechanism to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a compressor noise reduction housing mechanism to solve the problem mentioned in the background art that the sound insulation cotton is prone to loosening and displacement, resulting in sound insulation gaps and noise leakage.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A compressor noise reduction housing mechanism includes a compressor body, a damping protective layer fixedly connected to the outer wall of the compressor body, a housing body fixedly connected to the surface of the damping protective layer to protect the whole, sound-absorbing cotton provided between the damping protective layer and the housing body, a plurality of mounting cone rods provided inside the sound-absorbing cotton to stabilize the sound-absorbing cotton, a disassembly mechanism for easy disassembly of the sound-absorbing cotton provided on one side of the mounting cone rod, and a stabilizing mechanism for easy stabilization of the sound-absorbing cotton provided inside the mounting cone rod.

[0009] The compressor body has several heat sinks fixedly installed inside the casing to dissipate heat.

[0010] A heat dissipation spiral tube is fixedly installed between several of the heat sinks to facilitate heat dissipation of the compressor body.

[0011] The disassembly mechanism includes a mounting bracket fixedly connected to one end of several mounting cone rods, a damping protective layer and a fixing plate engaged with one side of the housing body, and a fixing bolt threadedly connected to one side of the housing body to fix the fixing plate, with one end of the fixing bolt penetrating the surface of the fixing plate.

[0012] The stabilizing mechanism includes a stabilizing screw rotatably connected inside the mounting cone rod, a movable plate threadedly connected to the surface of the stabilizing screw, a connecting rod rotatably connected to the surface of the movable plate, a stabilizing rod rotatably connected to one end of the connecting rod, and the stabilizing rod slidably connected to the surface of the stabilizing screw.

[0013] One end of the stabilizing screw has a fixing groove, and a fixing block that matches the fixing groove is fixedly connected to one side of the fixing plate. The fixing block is movably engaged in the fixing groove.

[0014] A support frame is fixedly connected to the surface of the compressor body, a base plate is provided at the bottom of the support frame, and a vibration damping block is provided between the base plate and the support frame.

[0015] A filter screen is fixedly connected to the air inlet of the compressor body, and a scraper for cleaning the surface of the filter screen is rotatably connected to the surface of the filter screen.

[0016] A honeycomb panel is fixedly connected to one side of the filter screen, and a sound-absorbing material for silencing the air intake is fixedly connected to the inner wall of the honeycomb panel.

[0017] The scraper surface is provided with guide grooves to facilitate gas flow.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0019] By inserting several mounting cone rods into the sound-absorbing cotton, placing the sound-absorbing cotton between the damping protective layer and the machine housing, and rotating the stabilizing screw, the stabilizing screw drives the moving plate to slide inside the mounting cone rod. The moving plate drives the connecting rod to move, causing the other end of the connecting rod to drive the stabilizing rod to slide on the surface of the stabilizing screw, so that the stabilizing rod is inserted into the sound-absorbing cotton on the surface of the mounting cone rod, thus stabilizing the sound-absorbing cotton. The damping protective layer protects the compressor body during operation, and the sound-absorbing cotton reduces the internal noise of the compressor body during operation. The machine housing protects the entire device, ensuring that the sound-absorbing cotton does not loosen or shift under the high-frequency vibration of the compressor body, thereby improving the stability of the sound-absorbing cotton.

[0020] The compressor body's heat is absorbed by several heat sinks, and the heat sink's spiral tube absorbs the heat from the surface of the heat sinks. When air passes through the spiral tube, it comes into contact with the inside of the spiral tube and carries away the high temperature from the surface of the spiral tube, thus completing the heat dissipation of the compressor body and improving the heat dissipation effect.

[0021] By inserting several mounting cones into the sound-absorbing cotton, placing the sound-absorbing cotton between the damping protective layer and the main body of the casing, the mounting bracket is snapped into one side of the damping protective layer and the main body of the casing. The fixing plate presses against the surface of the mounting bracket, and one end of the fixing bolt passes through the surface of the fixing plate, so that the other end of the fixing bolt is threaded to one side of the main body of the casing, thus completing the fixing of the mounting bracket and the mounting cones. To disassemble, the fixing bolt is removed, and then the several mounting cones are slid out, thus completing the installation and disassembly of the sound-absorbing cotton, which facilitates timely replacement of the sound-absorbing cotton.

[0022] The compressor body is fixed to the location where it needs to work by means of a base plate. When the compressor body is working, the vibration damping block reduces the vibration of the compressor body to prevent excessive vibration.

[0023] When the compressor is working, the gas passes through the filter screen to reach the inside of the compressor. The filter screen filters the air, and at the same time, the gas drives the scraper to rotate on the surface of the filter screen, cleaning the surface of the filter screen in real time. The guide grooves on the surface of the scraper cut the gas, which facilitates the gas flow and reduces noise. When the gas reaches the honeycomb plate, the noise at the air inlet of the compressor body is eliminated by the sound-absorbing material inside the honeycomb plate, further improving the noise reduction effect.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-4 This utility model provides a technical solution:

[0031] like Figures 1-4 As shown, a compressor noise reduction housing mechanism includes a compressor body 1. A damping protective layer 2 is fixedly connected to the outer wall of the compressor body 1. A housing body 3, which protects the entire structure, is fixedly connected to the surface of the damping protective layer 2. A sound-absorbing cotton 4 is provided between the damping protective layer 2 and the housing body 3. Several mounting cones 5 are provided inside the sound-absorbing cotton 4 to stabilize it. A disassembly mechanism for easy disassembly of the sound-absorbing cotton 4 is provided on one side of the mounting cones 5. A stabilizing mechanism for stabilizing the sound-absorbing cotton 4 is provided inside the mounting cones 5.

[0032] like Figures 1-4 As shown, by inserting the mounting cone rod 5 into the sound-absorbing cotton 4 and then driving the stabilizing mechanism, the sound-absorbing cotton 4 is stabilized on the surface of the mounting cone rod 5. Then, the sound-absorbing cotton 4 is installed between the damping protective layer 2 and the housing body 3 through the disassembly mechanism. The damping protective layer 2 protects the compressor body 1 during operation, and the sound-absorbing cotton 4 reduces the internal noise of the compressor body 1 during operation. The housing body 3 protects the entire device, so that the sound-absorbing cotton does not loosen or shift under the high-frequency vibration of the compressor body 1, thus improving the stability of the sound-absorbing cotton.

[0033] Furthermore, such as Figure 1 and Figure 2 As shown, a plurality of heat sinks 6 for dissipating heat from the compressor body 1 are fixedly installed inside the housing body 3, and heat dissipation spiral tubes 7 for facilitating heat dissipation from the compressor body 1 are fixedly installed between the plurality of heat sinks 6.

[0034] Several heat sinks 6 absorb the heat generated by the compressor body 1, and the heat dissipation spiral tube 7 absorbs the heat on the surface of the heat sinks 6. When air passes through the heat dissipation spiral tube 7, the air comes into contact with the inside of the heat dissipation spiral tube 7, and the air carries away the high temperature on the surface of the heat dissipation spiral tube 7, thus completing the heat dissipation of the compressor body 1 and improving the heat dissipation effect.

[0035] Furthermore, such as Figures 1-4 As shown, the disassembly mechanism includes a mounting bracket 8 fixedly connected to one end of several mounting cone rods 5, a fixing plate 9 engaged with one side of the damping protective layer 2 and the housing body 3, and a fixing bolt 10 threadedly connected to one side of the housing body 3 to fix the fixing plate 9, with one end of the fixing bolt 10 penetrating the surface of the fixing plate 9.

[0036] Insert several mounting cone rods 5 into the sound-absorbing cotton 4, place the sound-absorbing cotton 4 between the damping protective layer 2 and the housing body 3, so that the mounting bracket 8 is inserted into the damping protective layer 2 and the housing body 3 on one side, and the fixing plate 9 presses against the surface of the mounting bracket 8. One end of the fixing bolt 10 passes through the surface of the fixing plate 9, so that one end of the fixing bolt 10 is threaded to one side of the housing body 3, thus completing the fixing of the mounting bracket 8 and the mounting cone rods 5. When disassembling, remove the fixing bolt 10, and then slide out the several mounting cone rods 5 to complete the installation and disassembly of the sound-absorbing cotton 4, which is convenient for timely replacement of the sound-absorbing cotton 4.

[0037] Furthermore, such as Figures 1-4 As shown, the stabilizing mechanism includes a stabilizing screw 11 rotatably connected inside the mounting cone rod 5. A movable plate 12 is threadedly connected to the surface of the stabilizing screw 11. A connecting rod 13 is rotatably connected to the surface of the movable plate 12. A stabilizing rod 14 is rotatably connected to one end of the connecting rod 13. The stabilizing rod 14 is slidably connected to the surface of the stabilizing screw 11. A fixing groove 15 is provided at one end of the stabilizing screw 11. A fixing block 16 adapted to the fixing groove 15 is fixedly connected to one side of the fixing plate 9. The fixing block 16 is movably engaged in the fixing groove 15.

[0038] Rotate the stabilizing screw 11, causing the stabilizing screw 11 to drive the moving plate 12 to slide inside the mounting cone rod 5. The moving plate 12 then drives the connecting rod 13 to move, causing the other end of the connecting rod 13 to drive the stabilizing rod 14 to slide on the surface of the stabilizing screw 11. The stabilizing rod 14 is then inserted into the sound-absorbing cotton 4 on the surface of the mounting cone rod 5, thus stabilizing the sound-absorbing cotton 4. After the stabilizing screw 11 is adjusted, the fixing plate 9 drives the fixing block 16 to engage in the fixing groove 15, thus fixing the stabilizing screw 11.

[0039] Furthermore, such as Figures 1-3As shown, a support frame 17 is fixedly connected to the surface of the compressor body 1. A base plate 18 is provided at the bottom of the support frame 17. A vibration damping block 19 is provided between the base plate 18 and the support frame 17. A filter screen 20 is fixedly connected to the air inlet of the compressor body 1. A scraper 21 for cleaning the surface of the filter screen 20 is rotatably connected to the surface of the filter screen 20. A honeycomb plate 22 is fixedly connected to one side of the filter screen 20. A sound-absorbing material 23 for silencing the air inlet is fixedly connected to the inner wall of the honeycomb plate 22. A guide groove 24 for facilitating gas flow is provided on the surface of the scraper 21.

[0040] The support frame 17 is bolted to the compressor body 1. When disassembling the sound-absorbing cotton 4, the support frame 17 needs to be separated from the compressor body 1. The compressor body 1 is then fixed to the working location using the base plate 18. When the compressor body 1 is working, the vibration damping block 19 dampens the compressor body 1 to prevent excessive vibration. When the compressor body 1 is working, the gas passes through the filter screen 20 to reach the interior of the compressor body 1. The filter screen 20 filters the air, and at the same time, the gas drives the scraper 21 to rotate on the surface of the filter screen 20, cleaning the surface of the filter screen 20 in real time. The guide groove 24 on the surface of the scraper 21 cuts the gas, facilitating gas flow and reducing noise. When the gas reaches the honeycomb plate 22, the sound-absorbing material 23 inside the honeycomb plate 22 eliminates the noise at the air inlet of the compressor body 1, further improving the noise reduction effect.

[0041] The sound-absorbing material 23 is existing technology and will not be described in detail.

[0042] The working principle of this compressor noise reduction housing mechanism is as follows:

[0043] By inserting several mounting cone rods 5 into the sound-absorbing cotton 4, the sound-absorbing cotton 4 is placed between the damping protective layer 2 and the housing body 3. The stabilizing screw 11 is rotated, causing the stabilizing screw 11 to drive the moving plate 12 to slide inside the mounting cone rod 5. The moving plate 12 drives the connecting rod 13 to move, causing the other end of the connecting rod 13 to drive the stabilizing rod 14 to slide on the surface of the stabilizing screw 11. The stabilizing rod 14 is then inserted into the sound-absorbing cotton 4 on the surface of the mounting cone rod 5, thus stabilizing the sound-absorbing cotton 4. The damping protective layer 2 protects the compressor body 1 during operation, and the sound-absorbing cotton 4 reduces the internal noise of the compressor body 1 during operation. The housing body 3 protects the entire device, ensuring that the sound-absorbing cotton does not loosen or shift under the high-frequency vibration of the compressor body 1, thereby improving the stability of the sound-absorbing cotton.

[0044] The heat generated by the compressor body 1 is absorbed by several heat sinks 6, and the heat sink 7 absorbs the heat on the surface of the heat sinks 6. When air passes through the heat sink 7, the air comes into contact with the inside of the heat sink 7 and carries away the high temperature on the surface of the heat sink 7, thus completing the heat dissipation of the compressor body 1 and improving the heat dissipation effect.

[0045] By inserting several mounting cone rods 5 into the sound-absorbing cotton 4, the sound-absorbing cotton 4 is placed between the damping protective layer 2 and the housing body 3. The mounting bracket 8 is then inserted into one side of the damping protective layer 2 and the housing body 3. The fixing plate 9 presses against the surface of the mounting bracket 8. One end of the fixing bolt 10 passes through the surface of the fixing plate 9, and the other end of the fixing bolt 10 is threaded to one side of the housing body 3, thus completing the fixing of the mounting bracket 8 and the mounting cone rods 5. When disassembling, the fixing bolt 10 is removed, and then the several mounting cone rods 5 are slid out to complete the installation and disassembly of the sound-absorbing cotton 4, facilitating timely replacement of the sound-absorbing cotton 4.

[0046] The compressor body 1 is fixed in the place where it needs to work by the base plate 18. When the compressor body 1 is working, the vibration damping block 19 dampens the compressor body 1 to prevent excessive vibration when the compressor body 1 is working.

[0047] When the compressor body 1 is working, the gas passes through the filter screen 20 to reach the interior of the compressor body 1. The filter screen 20 filters the air, and at the same time, the gas drives the scraper 21 to rotate on the surface of the filter screen 20, cleaning the surface of the filter screen 20 in real time. The guide grooves 24 on the surface of the scraper 21 cut the gas, which facilitates the gas flow and reduces noise. When the gas reaches the honeycomb plate 22, the noise at the air inlet of the compressor body 1 is eliminated by the sound-absorbing material 23 inside the honeycomb plate 22, further improving the noise reduction effect.

[0048] Although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
