Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to a horizontal four-cylinder air compressor. Background Art

[0002] A horizontal four-cylinder air compressor is an air compressor designed in a horizontal layout. It has four cylinders and is usually equipped with an efficient compression mechanism and power system. Therefore, it can improve the air compression efficiency and air extraction performance to a certain extent, reduce energy loss, and improve overall work efficiency.

[0003] For example, a four-cylinder air compressor with the publication number CN220539793U specifically discloses an air compressor body, the bottom of the front and rear sides of the air compressor body are provided with pulleys, the bottom of the front and rear sides of the air compressor body are fixedly connected with positioning components, the two sides of the front and rear sides of the air compressor body are fixedly connected with fixed rods, the tops of the four fixed rods are fixedly connected with positioning frames, and the left side of the inner cavity of the positioning frame is fixedly connected with a driving motor. The utility model solves the problem that the existing four-cylinder air compressor has a large number of cylinders, and the heat generated when the cylinders are in operation is easy to accumulate and difficult to dissipate, resulting in damage to internal parts, thereby shortening the service life of the air compressor by setting an air compressor body, a pulley, a positioning component, a fixed rod, a positioning frame, a driving motor, a reciprocating screw, a first threaded sleeve, a cooling fan, a fixed ring, a groove, a filter plate, a limit ring, a sliding sleeve and a sliding rod.

[0004] However, the patent still has the following problems: the device dissipates heat from the cylinder by setting a reciprocating cooling fan on the top of the air compressor. However, since the four-cylinder air compressor has a large number of cylinders and generates a large amount of heat, the heat dissipation by a single fan will make it difficult to completely disperse the heat on the cylinder surface, and there is a time interval when the airflow dissipates heat for a single cylinder, causing the air compressor to continue to heat up during long-term operation, resulting in poor heat dissipation. Utility Model Content

[0005] The utility model aims to provide a horizontal four-cylinder air compressor, which has the advantage of being able to dissipate heat and cool the air compressor by combining water cooling and air cooling, thereby solving the problem of poor heat dissipation effect when the current four-cylinder air compressor is in use.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A horizontal four-cylinder air compressor comprises an air compressor body, the surface of the air compressor body is provided with a cooling mechanism and a filtering mechanism, the cooling mechanism comprises a mounting frame, a plurality of fans are fixed on the surface of the mounting frame, an air guide shell is fixed on the bottom of the mounting frame, a plurality of accelerating sleeves are connected to the surface of the air guide shell, a liquid storage tank is fixed on the surface of the air compressor body, a delivery pump is connected to the top of the liquid storage tank through a pipeline, one end of the delivery pump is connected to a delivery pipe, a plurality of first cooling pipes are fixed on the surface of the air compressor body cylinder, the delivery pipe is connected to the first cooling pipe, a plurality of second cooling pipes are connected to the surface of the first cooling pipe, a return pipe is connected to the bottom of the lower side of the first cooling pipe, and a semiconductor refrigerator is fixed on the surface of the liquid storage tank.

[0008] Preferably, the above-mentioned filtering mechanism includes a diverter pipe, which is connected to the gas interface of the air compressor body, and the surface of the diverter pipe is connected to two regulating valves, and the surface of the regulating valve on one side is connected to a filter box, and the surface of the filter box is connected to a pipe joint, and the inner wall of the filter box is provided with a filter plate and a filter screen.

[0009] Preferably, the filter screen is located on the right side of the filter plate, and the filter plate is a HEPA filter plate.

[0010] Preferably, a plurality of limiting shells are fixed to the inner wall of the filter box, the filter screen is slidably connected to the inner wall of the limiting shell, a closed door slides through the surface of the filter box, and a sealing gasket is fixed to the surface of the closed door.

[0011] Preferably, the surface of the second cooling pipe is connected to a plurality of partition pipes, and the partition pipes are located between a plurality of cylinders at the top of the air compressor body.

[0012] Preferably, a diameter-changing portion is provided on the surface of the conveying pipe.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model can effectively disperse the heat generated by the air compressor body when it is working by setting the cooling mechanism. When the air compressor body is working and generating heat, the fan is started, and the fan blows the airflow to the inside of the air guide shell, so that the airflow can be blown to the cylinder surface at the top of the air compressor body through multiple funnel-shaped accelerating sleeves. When the air passes through the accelerating sleeves with gradually reduced cross-sections, according to the Bernoulli principle, the air flow rate increases and the pressure increases, and the corresponding air flow temperature will also decrease accordingly, thereby improving the heat dissipation effect on the surface of the air compressor body. The liquid storage tank can be filled with low-temperature coolant. When the delivery pump is started, the coolant can be delivered to the multiple first cooling pipes through the delivery pipe, and the low-temperature coolant will exchange heat with the first cooling pipes. The first cooling tube can continuously absorb and reduce the cylinder surface temperature. At the same time, the coolant inside the first cooling tube will flow into the second cooling tube, and then flow from the second cooling tube to the inside of the multiple first cooling tubes on the lower side. This will cause the coolant fluid to collide and mix at the intersection, thereby forming turbulence. Under the turbulent state, the molecules in the fluid are more fully mixed, which improves the fluid heat exchange efficiency and the heat transfer rate per unit area, so that the heat generated by the air compressor body when working can be quickly cooled, and the coolant passing through the first cooling tube and the second cooling tube can flow back to the liquid storage tank through the reflux pipe. The semiconductor refrigerator can cool the liquid storage tank when working, so as to ensure that the coolant is in a low temperature state. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

A cooling mechanism 2 and a filtering mechanism 3 are arranged on the surface of the air compressor body 1. The cooling mechanism 2 can effectively disperse the heat generated by the air compressor body 1 when it is working, and the filtering mechanism 3 can achieve a filtering effect when the air compressor body 1 is pumping air.

[0021] Specifically, the cooling mechanism 2 includes a mounting frame 201, which is fixed to the top of the air compressor body 1, and a plurality of fans 202 are fixed on the surface of the mounting frame 201. An air guide shell 203 is fixed to the bottom of the mounting frame 201. The surface of the air guide shell 203 is connected to a plurality of accelerating sleeves 204, and the accelerating sleeves 204 are arranged in a funnel-shaped structure. A liquid storage tank 205 is fixed to the surface of the air compressor body 1, and a delivery pump 206 is connected to the top of the liquid storage tank 205 through a pipeline. The delivery pump 206 is fixedly connected to the surface of the air compressor body 1, and one end of the delivery pump 206 is connected to The delivery pipe 207 and a plurality of first cooling pipes 208 are fixed on the surface of the cylinder of the air compressor body 1. The delivery pipe 207 is connected to the first cooling pipe 208. The surface of the first cooling pipe 208 is connected to a plurality of second cooling pipes 209. Both the first cooling pipe 208 and the second cooling pipe 209 are made of copper alloy. The bottom of the lower first cooling pipe 208 is connected to a return pipe 210. The bottom of the return pipe 210 is connected to the top of the liquid storage tank 205. A semiconductor refrigerator 211 is fixed on the surface of the liquid storage tank 205. A heat dissipation structure is arranged on the surface of the semiconductor refrigerator 211.

[0022] In the above design, when the air compressor body 1 is working and generating heat, the fan 202 is started, and the fan 202 will blow the air flow into the air guide shell 203, so that the air flow can be blown to the cylinder surface at the top of the air compressor body 1 through multiple funnel-shaped accelerating sleeves 204. When the air passes through the accelerating sleeves 204 with gradually decreasing cross-sections, according to the Bernoulli principle, the air flow rate increases and the pressure increases, and the corresponding air flow temperature will also decrease accordingly, thereby improving the heat dissipation effect on the surface of the air compressor body 1. The liquid storage tank 205 can be filled with low-temperature coolant. When the delivery pump 206 is started, the coolant can be delivered to the multiple first cooling pipes 208 through the delivery pipe 207, and the low-temperature coolant will exchange heat with the first cooling pipes 208, so that the first cooling pipes 208 can continuously absorb and reduce The cylinder surface temperature is low, and at the same time, the coolant in the first cooling tube 208 will flow into the second cooling tube 209, and then flow from the second cooling tube 209 to the multiple first cooling tubes 208 on the lower side, which will cause the coolant fluid to collide and mix at the intersection, thereby forming turbulence. Under the turbulent state, the molecules in the fluid are more fully mixed, which improves the fluid heat exchange efficiency and the heat transfer rate per unit area, so that the heat generated by the air compressor body 1 during operation can be quickly cooled, and the coolant passing through the first cooling tube 208 and the second cooling tube 209 can be returned to the liquid storage tank 205 through the return pipe 210, and the semiconductor refrigerator 211 can cool the liquid storage tank 205 when working, so as to ensure that the coolant is in a low temperature state.

[0023] Furthermore, the filtering mechanism 3 includes a shunt pipe 301, which is connected to the gas interface of the air compressor body 1, and the surface of the shunt pipe 301 is connected to two regulating valves 302, and the surface of the regulating valve 302 on one side is connected to a filter box 303, and the surface of the filter box 303 is connected to a pipe joint 306, and the inner wall of the filter box 303 is provided with a filter plate 305 and a filter screen 304. With the above design, the compressed air inside the air compressor body 1 can be transported to the pipeline connected to the outside through the shunt pipe 301 and the regulating valve 302 on one side, and when the air compressor body 1 is adjusted to the exhaust working state, the pipe joint 306 can be connected to the exhaust pipeline, and the outside air will be sucked into the filter box 303, the filter screen 304 can preliminarily filter the impurities in the air, and the filter plate 305 can filter again, so as to prevent dust from entering the air compressor body 1.

[0024] Furthermore, the filter screen 304 is located on the right side of the filter plate 305, and the filter plate 305 is a HEPA filter plate. With the above design, the filter screen 304 can first contact the extracted air, so that the filter screen 304 can capture larger particles and protect the fine filter plate 305 behind it. The HEPA filter plate 305 can capture at least 99.97% of particles with a diameter of 0.3 microns, thereby further improving the air filtration effect.

[0025] Furthermore, a plurality of limiting shells 307 are fixed to the inner wall of the filter box 303, the filter screen 304 is slidably connected to the inner wall of the limiting shell 307, a closed door 308 is slidably penetrated through the surface of the filter box 303, and a sealing gasket is fixed to the surface of the closed door 308. With the above design, the limiting shell 307 can limit the filter screen 304 and the filter plate 305, and the closed door 308 can seal the filter box 303 with the sealing gasket, and the top of the filter box 303 can be opened by pulling the closed door 308 upwards, so that the operator can pull the filter screen 304 and the filter plate 305 upwards to remove and clean them.

[0026] Furthermore, the surface of the second cooling pipe 209 is connected to a plurality of separation pipes 212, and the separation pipes 212 are located between the plurality of cylinders at the top of the air compressor body 1. With the above design, the separation pipes 212 can absorb the heat generated between the front and rear cylinders, so that the heat between the cylinders on both sides can be normally dispersed, thereby making the cooling effect of the plurality of cylinders more uniform and avoiding local overheating.

[0027] Furthermore, a diameter reducing portion 213 is provided on the surface of the delivery pipe 207. With the above design, when the coolant passes through the delivery pipe 207 and enters the inside of the diameter reducing portion 213, the cross section is deformed from large to large, thereby increasing the cooling fluid pressure and flow rate, so that the high-speed coolant can take away the heat from the surfaces of the first cooling pipe 208 and the second cooling pipe 209 more quickly.
