Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to a half-load system for a low-energy air compressor. Background Art

[0002] An air compressor, also known as an air compressor, is a device used to compress gas. In modern industrial production, air compressors are widely used in various fields, such as machinery manufacturing, chemical industry, construction, and mining. With the continuous development of industry, the demand for compressed air is also increasing.

[0003] Traditional air compressors typically consist of an electric motor, a compression mechanism, and an air tank. The motor drives the compression mechanism, drawing in air, compressing it to a certain pressure, and storing it in the air tank for later use. However, existing air compressors present several operational challenges. On the one hand, due to limitations in their operating principles and structural design, they consume high energy, with a significant amount of electricity consumed in the air compression process. On the other hand, air compressors generate significant heat during operation, and existing heat dissipation methods are often inefficient, making it difficult to effectively dissipate this heat. This not only affects the compressor's efficiency but can also shorten its service life.

[0004] Therefore, reducing the energy consumption of air compressors and improving heat dissipation efficiency have become issues that need to be urgently addressed. Utility Model Content

[0005] Based on the above problems existing in the prior art, the purpose of the embodiments of the present invention is to provide a low-energy air compressor half-load system that automatically adjusts the air intake volume and temperature of the air compressor to extend the service life of the air compressor.

[0006] The technical solution adopted by the utility model to solve the technical problem is: a low-energy air compressor half-load system, including an air compressor, a cooling coil, an electric water pump and a temperature sensor;

[0007] The cooling coil is coiled on the air compressor, one end of the cooling coil is connected to a water inlet pipe, the other end of the cooling coil is connected to a drain pipe, the output end of the electric water pump is connected to the water inlet pipe, and the temperature sensor is arranged on the drain pipe.

[0008] Furthermore, a voltage regulator is electrically connected between the electric water pump and the temperature sensor.

[0009] Furthermore, the air compressor is provided with an air intake pipe, the air intake pipe is provided with an electric valve, and a second voltage regulator is electrically connected between the electric valve and the temperature sensor.

[0010] Furthermore, a filter 1 is provided on the air intake pipe.

[0011] Furthermore, the air compressor is provided with an exhaust pipe, and the exhaust pipe is provided with a second filter.

[0012] Furthermore, a cooling component is provided on the exhaust pipe, a diversion pipe is provided between the cooling component and the water inlet pipe, and the diversion pipe is communicated with the cooling component and the water inlet pipe respectively.

[0013] Furthermore, the cooling component includes an inner cylinder, which is sleeved on the outside of the exhaust pipe. A plurality of vertical grooves are opened inside the inner cylinder, and the directions of the vertical grooves are parallel to the central axis of the inner cylinder.

[0014] Furthermore, the cooling component includes a spiral coil, which is coiled around the outer wall of the inner tube. One end of the spiral coil is provided with a docking pipe 1, and the other end of the spiral coil is provided with a docking pipe 2, and the docking pipe 1 is connected to the diversion pipe.

[0015] Furthermore, a plurality of heat sinks are provided on the outside of the inner cylinder, and the heat sinks are located on the outside of the spiral coil.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] 1. The temperature sensor detects the temperature of the cooling medium when it is discharged from the drain pipe. Based on this temperature, the voltage regulator 1 is controlled to adjust the voltage of the electric valve and the electric water pump respectively. That is, when the temperature sensor detects that the temperature of the cooling medium when it is discharged from the drain pipe is high, the voltage of the voltage regulator 1 is increased, the power of the electric water pump is increased, the circulation speed of the cooling medium in the cooling coil is increased, and the cooling of the air compressor is accelerated. On the contrary, the voltage of the voltage regulator 1 is reduced, the power of the electric water pump is reduced, the circulation speed of the cooling medium is slowed down, and the cooling medium is saved.

[0018] 2. When the temperature sensor detects that the temperature of the cooling medium discharged from the drain pipe is high, the voltage regulator 2 adjusts the voltage to increase, the electric valve closing angle increases, and the gas flow rate in the intake pipe is reduced, so that the air intake volume of the air compressor is reduced, the internal energy generated by the air compression is reduced, and the temperature generated is reduced, thereby preventing the air compressor from being affected by excessive temperature and affecting its service life. On the contrary, the voltage regulator 2 adjusts the voltage to decrease, the air intake volume is increased, and the efficiency of the air compressor in compressing gas is improved;

[0019] 3. The added cooling component can reduce the temperature of the compressed gas discharged from the air compressor, saving the time cost of subsequent cooling of the compressed gas. During this process, part of the cooling medium enters the spiral coil along the diversion pipe and flows along the spiral coil. The inner tube adheres to the outer wall of the exhaust pipe to absorb the heat of the exhaust pipe. The heat is then absorbed and discharged by the cooling medium circulating in the spiral coil. Part of the heat is absorbed by the heat sink and dissipated into the air.

[0020] 4. Because there are several vertical grooves inside the inner tube, there are several gaps between the inner tube and the outer wall of the exhaust pipe when they are fitted together. The heat of the compressed air inside the exhaust pipe is dissipated outward, and the inner tube is cooled by the cooling medium in the external spiral coil, so that convection is generated in the gap between the inner tube and the exhaust pipe due to the temperature difference, thereby improving the efficiency of dissipating the heat of the compressed air inside the exhaust pipe.

[0034] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0035] See also Figure 1-2 , this utility model provides a technical solution:

[0036] A low-energy air compressor half-load system includes an air compressor 1, a cooling coil 2, an electric water pump 3, and a temperature sensor 4;

[0037] The air compressor 1 is provided with an air intake pipe 11 and an exhaust pipe 12 . The air intake pipe 11 is provided with a filter 111 , an electric valve 112 , and the exhaust pipe 12 is provided with a filter 2 121 and a cooling component 7 .

[0038] The cooling coil 2 is coiled on the air compressor 1, one end of the cooling coil 2 is connected to the water inlet pipe 21, and the other end of the cooling coil 2 is connected to the drain pipe 23. A diverter pipe 22 is provided between the cooling component 7 and the water inlet pipe 21, and the diverter pipe 22 is connected to the cooling component 7 and the water inlet pipe 21 respectively.

[0039] The output end of the electric water pump 3 is connected to the water inlet pipe 21 , and a voltage regulator 5 is electrically connected between the electric water pump 3 and the temperature sensor 4 , which is arranged on the drain pipe 23 .

[0040] A voltage regulator 2 6 is electrically connected between the electric valve 112 and the temperature sensor 4 .

[0041] The cooling assembly 7 includes an inner cylinder 71 and a spiral coil 72 .

[0042] The inner tube 71 is sleeved on the outside of the exhaust pipe 12, and a plurality of vertical grooves 710 are opened inside the inner tube 71. The direction of the vertical grooves 710 is parallel to the central axis of the inner tube 71. The spiral coil 72 is coiled on the outer wall of the inner tube 71. One end of the spiral coil 72 is provided with a docking pipe 1 721, and the other end of the spiral coil 72 is provided with a docking pipe 2 722. The docking pipe 1 721 is connected to the diversion pipe 22. A plurality of heat sinks 711 are provided on the outside of the inner tube 71, and the heat sink 711 is located on the outside of the spiral coil 72.

[0043] When the air compressor 1 is running, the compressed air inside it will generate high temperature. At this time, the electric water pump 3 is started to pump cooling medium into the cooling coil 2. The cooling coil 2 is wound around the air compressor 1. The cooling medium flowing therein accelerates the cooling of the air compressor 1, and then the cooling medium is discharged from the drain pipe 23.

[0044] The temperature sensor 4 detects the temperature of the cooling medium when it is discharged from the drain pipe 23, and controls the voltage regulator 5 and adjusts the voltages of the electric valve 112 and the electric water pump 3 according to the temperature therein. That is, when the temperature sensor 4 detects that the temperature of the cooling medium when it is discharged from the drain pipe 23 is high, the voltage of the voltage regulator 5 increases, the power of the electric water pump 3 is increased, the circulation speed of the cooling medium in the cooling coil 2 is increased, and the cooling of the air compressor 1 is accelerated. On the contrary, the voltage of the voltage regulator 5 decreases, the power of the electric water pump 3 decreases, the circulation speed of the cooling medium is slowed down, and the cooling medium is saved.

[0045] When the temperature sensor 4 detects that the temperature of the cooling medium discharged from the drain pipe 23 is high, the voltage regulator 2 6 adjusts the voltage to increase, the closing angle of the electric valve 112 increases, and the gas flow rate in the intake pipe 11 is reduced, so that the intake volume of the air compressor 1 is reduced, the internal energy generated by the air compression therein is reduced, and the temperature generated is reduced, thereby preventing the service life of the air compressor 1 from being affected by excessive temperature. Conversely, the voltage regulator 2 6 adjusts the voltage to decrease, the intake volume is increased, and the efficiency of the air compressor 1 in compressing gas is improved.

[0046] The newly added filter 111 and filter 2 121 can filter the gas when it enters and exits the air compressor 1 , thereby preventing impurities in the gas from entering the air compressor 1 and also preventing the quality of the compressed gas from being affected.

[0047] The added cooling component 7 can reduce the temperature of the compressed gas discharged from the air compressor 1, saving the time cost of subsequent reduction of the compressed gas. During this process, part of the cooling medium enters the spiral coil 72 along the diversion pipe 22 and flows spirally along the spiral coil 72. The inner tube 71 adheres to the outer wall of the exhaust pipe 12 to absorb the heat of the exhaust pipe 12, and then the heat is absorbed and discharged by the cooling medium circulating in the spiral coil 72, and part of the heat is absorbed by the heat sink 711 and dissipated into the air.

[0048] In addition, since a number of vertical grooves 710 are provided inside the inner tube 71, when the inner tube 71 and the outer wall of the exhaust pipe 12 are fitted together, a number of gaps exist between the two. The heat of the compressed air inside the exhaust pipe 12 is dissipated outward, and the inner tube 71 is cooled by the cooling medium in the external spiral coil 72, so that convection is generated in the gap between the inner tube 71 and the exhaust pipe 12 due to the temperature difference, thereby improving the efficiency of dissipating the heat of the compressed air inside the exhaust pipe 12 outward.

[0049] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the scope of the present invention. The technical scope of this utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
