Description

TECHNICAL FIELD

[0001] The application relates to the field of air compressors, and particularly relates to an air compressor with high heat dissipation performance. BACKGROUND

[0002] A high-pressure compressor is a mechanical structure used for improving gas pressure and conveying gas, and belongs to a working machine for converting power energy of a prime mover into gas pressure energy. The high-pressure compressor is various in types and wide in use, and is called a general machine. The compressor is extremely widely applied in many departments of national economy and national defense construction, and has become an indispensable key equipment in the industrial fields of petroleum, chemical industry and power, etc. In chemical production, in order to ensure that some synthesis processes can be carried out at high pressure, the compressor is used to pressurize gas to the required pressure. In addition, refrigeration and gas separation also cannot be separated from compressed gas.

[0003] According to the patent No. CN220955980U disclosed by the Chinese patent network, the utility model discloses an oil-free air compressor with improved heat dissipation performance, which comprises an oil-free air compressor body, a box body fixed to the upper side of the oil-free air compressor body, a compression box arranged in the box body, a first piston plate slidingly arranged in the compression box, a motor arranged in the box body, an oval plate sleeved on the output end of the motor, a rotating plate rotatably connected between the oval plate and the first piston plate, a cooling box arranged in the box body, a second piston plate slidingly arranged in the cooling box, two first water cooling plates fixed to the two sides of the compression box, and a second water cooling plate fixed to the upper end of the compression box. The utility model makes the air in the box body flow quickly by swinging the cover plate, so that the compression box and the motor are cooled, and the two first water cooling plates and the second water cooling plate are used for water cooling and heat dissipation outside the compression box, so that the box body is cooled in a double way.

[0004] Although the above-mentioned patent can realize double heat dissipation, when the air compressor is running, the water cooling plate can quickly cool, but since the cooling area is concentrated, the cooling gas used for cooling the air compressor is directly introduced into the air compressor and contacts the high-temperature parts, so that the expansion / contraction degrees of the parts in different areas are uneven, local stress concentration is caused, plastic deformation or micro-cracks are possibly caused, and the service life of the air compressor is reduced. Therefore, the application provides an air compressor with high heat dissipation performance to solve the above-mentioned problems. SUMMARY

[0006] To achieve the above object, the application provides the following technical scheme: an air compressor with high heat dissipation performance, comprising a supporting seat and a fixing seat fixedly connected to the top of the supporting seat, and a machine shell installed on the top of the fixing seat; a gradient heat dissipation mechanism located at the bottom of the fixing seat, comprising a heating box fixedly connected to the bottom of the fixing seat, an air inlet shell fixedly connected to the end of the heating box, a fan installed at the air inlet of the air inlet shell, three partitions fixedly connected to the inside of the heating box, four heating chambers divided by the three partitions in the heating box, and a heating pipe installed in each of the heating chambers; a first flow guide pipe arranged at the bottom of the heating box, four second electromagnetic valves fixedly connected to the air inlet of the first flow guide pipe, and each of the second electromagnetic valves in communication with one of the heating chambers; the four heating chambers in communication with the inside of the air inlet shell through a first electromagnetic valve and a U-shaped pipe fixedly connected to the first electromagnetic valve; and a channel switching assembly arranged in the inside of the heating box; and an adjusting mechanism located at one side of the machine shell, and an electromagnetic reversing valve fixedly connected to one side of the machine shell.

[0007] As a further scheme of the application, the channel switching assembly comprises through holes formed in the inner sides of the three partitions, the four heating chambers are in communication through the three through holes, a second flow guide pipe is installed at the air outlet of one of the heating chambers, one end of the second flow guide pipe penetrates to the outside of the heating box, and the through holes close to each other are arranged in front of and behind each other.

[0008] As a further scheme of the application, the channel switching assembly further comprises sealing baffles arranged at the ports of the through holes and the ports of the second flow guide pipes, one fixing seat is fixedly connected to one side of each of the partitions and one side of the heating box, the sealing baffles are rotatably connected to the inner side of the fixing seat, torsion springs are arranged between the sealing baffles and the fixing seat, and a power pushing unit is arranged on one side of the sealing baffle.

[0009] As a further further scheme of the present application: the power pushing unit comprises an electric push rod mounted on one side of the heating box, the output end of the electric push rod is connected with a connecting plate, the inner side of the connecting plate is fixedly connected with four rectangular rods, one end of each of the rectangular rods is fixedly connected with a U-shaped frame, the inner side of each of the U-shaped frames is rotatably connected with a roller, and the roller is attached to the outer wall of the sealing baffle.

[0010] As a further further scheme of the present application: the adjusting mechanism comprises an electromagnetic reversing valve fixedly connected to the other end of the first flow guide pipe, and the electromagnetic reversing valve is fixedly connected with a backflow air outlet pipe on one side.

[0011] As a further further scheme of the present application: the adjusting mechanism further comprises a plurality of cooling grooves opened in the inside of the shell, and a connecting groove is staggered between the two sides of every two cooling grooves.

[0012] As a further further scheme of the present application: the other end of the electromagnetic reversing valve is fixedly connected to one side of the shell and communicates with the cooling grooves.

[0013] As a further further scheme of the present application: the cooling grooves and the connecting grooves communicate to form a continuous air duct.

[0014] Compared with the prior art, the present application has the following beneficial effects:

[0015] 1. By cooperating the first electromagnetic valve and the second electromagnetic valve and other parts, 70-degree, 50-degree, 30-degree and 10-degree gases can be sequentially introduced into the inside of the shell for gradient cooling. Heat exchange can reduce the temperature inside the compressor, avoid component damage and performance decline caused by high temperature, and prolong the service life of the compressor. Moreover, compared with directly introducing low-temperature gas, sequentially introducing gases with different temperature gradients can make the temperature change more gentle, reduce thermal stress impact on the compressor caused by sharp temperature change, and further improve the overall service life of the compressor.

[0016] 2. By cooperating the second flow guide pipe and other parts, the air compressor can inhale high-temperature gas through the second flow guide pipe. Especially in a humid environment, cold air without heating may condense into water droplets in the compressor due to temperature rise during compression. These water droplets can corrode the components of the compressor and affect its performance and service life. Heating the air inlet of the air compressor when it is just running can improve the dew point temperature of the air and reduce the possibility of condensation, thereby protecting the compressor components from corrosion.

[0017] 3. By the cooperation of the electromagnetic reversing valve and other parts, the air flow passes through the continuous air duct (cooling groove + connecting groove) and flows through each part of the shell, avoiding the problem of insufficient end air flow and decreasing heat dissipation efficiency in traditional one-way flow. When switching the air inlet and outlet direction, the flow path of the air flow in the shell changes constantly, forming a turbulent effect, destroying the boundary layer of the heating surface, increasing the contact area of the air and the shell and the heat exchange efficiency. For example, when switching from two-side air inlet to middle air inlet, the air flow will produce cross flow at the connecting groove, strengthening the flushing effect on the heating element, thereby further improving the overall heat dissipation effect of the device.

[0031] Please refer to Figures 1-4The embodiment provides a high-heat-dissipation-performance air compressor which comprises a support base 1, a fixed base 2 fixedly connected to the top of the support base 1, and a machine shell 3 installed on the top of the fixed base 2. A gradient heat dissipation mechanism is arranged at the bottom of the fixed base 2 and comprises a heating box 4 fixedly connected to the bottom of the fixed base 2, an air inlet shell 5 fixedly connected to the end of the heating box 4, a fan 13 installed at the air inlet of the air inlet shell 5, three partition plates 11 fixedly connected to the inside of the heating box 4, four heating pipes 14 installed in the four heating compartments divided by the three partition plates 11, a first flow guide pipe 7 arranged at the bottom of the heating box 4, four second electromagnetic valves 10 fixedly connected to the air inlets of the first flow guide pipe 7 and in communication with the four heating compartments respectively, a first electromagnetic valve 9, a U-shaped pipe 6 in communication with the inside of the air inlet shell 5 and fixedly connected to the first electromagnetic valve 9, and a channel switching assembly arranged in the heating box 4. An adjusting mechanism is arranged at one side of the machine shell 3 and comprises an electromagnetic reversing valve 24 fixedly connected to one side of the machine shell 3. The channel switching assembly comprises four through holes 15 formed in the inner sides of the three partition plates 11, and the four heating compartments are in communication through the four through holes 15. A second flow guide pipe 12 is arranged at the air outlet of one of the heating compartments and penetrates through the heating box 4 to the outside of the heating box 4. The through holes 15 arranged in pairs are arranged in front of and behind each other. The channel switching assembly further comprises a sealing baffle 16 arranged at the ports of the through holes 15 and the ports of the second flow guide pipe 12. One side of each partition plate 11 and one side of the heating box 4 are fixedly connected with a fixed base 17. The sealing baffle 16 is rotatably connected to the inner side of the fixed base 17. The sealing baffle 16 is fixedly connected with a rotating shaft 19 at two sides thereof, and one end of the rotating shaft 19 penetrates through the fixed base 17 to the outside of the fixed base 17 and is rotatably connected with the fixed base 17. A torsional spring 20 is arranged between the rotating shaft 19 and the fixed base 17. A power pushing unit is arranged at one side of the sealing baffle 16.

[0032] The adjusting mechanism comprises the electromagnetic reversing valve 24 fixedly connected to the other end of the first flow guide pipe 7, and a backflow air outlet pipe 25 fixedly connected to one side of the electromagnetic reversing valve 24. The adjusting mechanism further comprises a plurality of cooling grooves 26 formed in the inside of the machine shell 3, and a connecting groove 27 arranged between the two sides of every two cooling grooves 26. The other end of the electromagnetic reversing valve 24 is fixedly connected to one side of the machine shell 3 and is in communication with the cooling grooves 26. The cooling grooves 26 and the connecting grooves 27 are in communication to form a continuous air duct.

[0033] The temperature inside the four heating bins heated by the heating pipe 14 from outside to inside is 70 degrees, 50 degrees, 30 degrees, and 10 degrees. When the inside of the casing 3 needs to be cooled, the fan 13 is started, the first electromagnetic valve 9 and the corresponding second electromagnetic valve 10 on the outermost side are opened, and the fan 13 blows external air into the U-shaped pipe 6 on the outermost side with the highest temperature. The air is heated to 70 degrees in the outermost heating bin, and then the heated air is introduced into the first flow guide pipe 7 through the second electromagnetic valve 10. At this time, the electromagnetic reversing valves 24 on both sides of the casing 3 are opened and the two electromagnetic reversing valves 24 in the middle are closed. The electromagnetic reversing valve 24 corresponding to the 70-degree heating bin blows air into the casing 3, and the electromagnetic reversing valve 24 on the other side blows air out through the backflow air pipe 25 (the electromagnetic reversing valve 24 of the switching channel does not blow air into the corresponding first flow guide pipe 7 at this time). Then, the 70-degree hot air is transported to the inside of the casing 3 through the first flow guide pipe 7. Since the temperature inside the casing 3 needs to be cooled at about 80 degrees, the temperature of 70 degrees is initially introduced for cooling, and the heat is discharged from the electromagnetic reversing valve 24 for external air exhaust. After the cooling cycle is completed, the first electromagnetic valve 9 and the second electromagnetic valve 10 connected to the 70-degree heating bin are closed, and the electromagnetic reversing valves 24 on both sides are set to exhaust air outward. The first electromagnetic valve 9 and the second electromagnetic valve 10 connected to the 50-degree heating bin are opened, and the electromagnetic reversing valves 24 connected to the 50-degree heating bin are opened. The air is cooled again in sequence, and the inside of the casing 3 is cooled in sequence to form a gradient. Heat exchange can reduce the temperature inside the compressor, avoid damage to components and performance degradation due to high temperature, and prolong the service life of the compressor. Moreover, compared with directly introducing low-temperature gas, the temperature change is more gradual, and the thermal stress impact on the compressor caused by rapid temperature change is reduced.

[0034] When the inside of the shell 3 needs to be cooled, the middle two electromagnetic reversing valves 24 are closed, and the two side electromagnetic reversing valves 24 are opened, the outflow directions of the two side electromagnetic reversing valves 24 are opposite, the electromagnetic reversing valve 24 in the forward direction is connected to the corresponding cooling groove 26, and the airflow in the 70-degree heating bin is introduced into the airflow in the 70-degree heating bin. The airflow in the 70-degree heating bin can pass through the continuous air duct to pass through the entire shell 3. In the stable running stage of the air compressor with high heat dissipation performance, the heat dissipated by the overall part is relatively uniform. At this time, the two side electromagnetic reversing valves 24 are changed to reverse running, and one electromagnetic reversing valve 24 is started to run forward. The 50-degree gas can be introduced into the shell 3 and discharged to the outside from the two side electromagnetic reversing valves 24. After a period of time, the 30-degree corresponding electromagnetic reversing valve 24 is started to run forward, and is discharged to the outside from the two side electromagnetic reversing valves 24. After a period of time, the last two electromagnetic reversing valves 24 in the middle are closed, the electromagnetic reversing valve 24 corresponding to the 70-degree is switched to pass through the backflow exhaust pipe 25 to exhaust air to the outside, and the electromagnetic reversing valve 24 corresponding to the 10-degree introduces the gas into the shell 3 and circulates for one circle. After being discharged, the airflow passes through the continuous air duct (cooling groove 26 + connecting groove 27) to flow through each part of the shell, avoiding the problem of insufficient airflow at the end and decreasing heat dissipation efficiency in the traditional one-way flow. For example, in the stable running stage, the electromagnetic reversing valve is reversed to run, so that the airflow passes through the shell from different directions, covering the "dead zone" (such as the corner and the leeward side of the heating element) that may be formed due to one-way flow. When the inlet and outlet air directions are switched, the airflow path in the shell changes constantly, forming a turbulent flow effect, breaking the boundary layer on the heating surface, increasing the contact area and heat exchange efficiency of the air and the shell. For example, when the air inlet is switched from the two sides to the middle, the airflow will produce cross-flow at the connecting groove 27, strengthening the scouring effect on the heating element, thereby further improving the overall heat dissipation effect of the device.

[0035] The above-mentioned four electromagnetic reversing valves 24 correspond to the second electromagnetic valve 10, which is opened when the corresponding electromagnetic reversing valve 24 introduces the gas into the shell 3, and is closed when the corresponding electromagnetic reversing valve 24 exhausts the gas, so as to ensure that the equipment can normally circulate.

[0036] Alternatively, the 30-degree determines the airflow in the heating bin according to the temperature inside the shell 3, and the airflow in the heating bin passes through the two side reverse running electromagnetic reversing valves 24 and is discharged from the backflow exhaust pipe 25 of the shell 3.

[0037] Please refer to Figures 5-7 The power pushing unit includes an electric push rod 23 installed on one side of the heating box 4. The output end of the electric push rod 23 is connected with a connecting plate 8. The inner side of the connecting plate 8 is fixedly connected with four rectangular rods 18. One end of each rectangular rod 18 is fixedly connected with a U-shaped frame 21. The inner side of each U-shaped frame 21 is rotatably connected with a roller 22, and the roller 22 is attached to the outer wall of the sealing baffle 16.

[0038] When the machine shell 3 just starts to run the initial stage, the first electromagnetic valve 9 communicated with the 10-degree heating bin is opened, at this time the four second electromagnetic valves 10 are in the closed state, the electric push rod 23 is started, the output end of the electric push rod 23 drives the connecting plate 8 to move away from the heating box 4, so as to drive a roller 22 to move away from the sealing baffle 16 through a rectangular rod 18 respectively, when the roller 22 is separated from the sealing baffle 16, the torsion spring 20 no longer drives the rotating shaft 19 to drive the sealing baffle 16 to reset, so that the through hole 15 is no longer blocked, after the air enters the 10-degree heating bin to be heated, it can enter the 30-degree, 50-degree and 70-degree heating bins through the through hole 15, and finally enters the air compressor inlet through the second flow guide pipe 12, so that the air compressor can inhale high-temperature gas, especially in a humid environment, cold air without heating enters the compressor just running inside, due to the temperature rise in the compression process, water vapor may condense into water droplets in the compressor, which will cause corrosion to the compressor parts, affect its performance and service life, and heating the air inlet of the air compressor just running can improve the dew point temperature of the air and reduce the possibility of condensation, protecting the compressor parts from corrosion;

[0039] The above is the air compressor initial operation, the air inlet is heated, after a period of operation, the air compressor has a certain temperature, and the air heating operation is stopped, and the heating device is used to realize the heat dissipation of the air compressor.

[0040] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art of air compressor can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
