Description

Technical Field

[0001] This application relates to the technical field of air compressors, and in particular to an energy-saving control device for air compressors. Background Technology

[0002] An air compressor, also known as an air compressor, is a device used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating, using rotary vanes or rotary screws. Centrifugal compressors are used in a wide range of applications. During the operation of the compressor, specifically the compression of air, high-temperature gas is generated. This heat can be recovered and utilized during the transportation of the compressed gas.

[0003] Related technologies include a heat recovery device for compressed gas in an air compressor, which includes an air delivery pipe connected to the air compressor and a water tank on one side of the air compressor. The air delivery pipe passes through the water tank and is arranged in a curved shape inside the water tank, which is filled with water. When the compressed gas is transported through the air delivery pipe, the heat is transferred to the water in the water tank, which is then heated and recovered for reuse.

[0004] In the aforementioned technologies, when high-temperature gas is transported to transfer heat to water, its temperature decreases, and it liquefies within the gas pipeline, producing liquid. As the amount of liquid gradually increases, it affects the gas transmission within the pipeline and also impacts the heat transfer efficiency. Summary of the Invention

[0005] In order to improve the efficiency of heat transfer, this application provides an energy-saving control device for air compressors.

[0006] The energy-saving control device for an air compressor provided in this application adopts the following technical solution:

[0007] An energy-saving control device for an air compressor includes an air compressor body and a water tank disposed on one side of the air compressor body. An air supply pipe is disposed on the air compressor body, passing through the water tank. The air supply pipe is bent vertically within the water tank. A mounting frame is disposed at the bottom of the water tank, and a recovery pipe is disposed within the mounting frame. The recovery pipe extends into the water tank and communicates with the bent portion at the bottom of the air supply pipe. A first control valve is disposed at the end of the recovery pipe opposite to the air supply pipe for controlling the closure of the recovery pipe. A collection device for collecting liquefied liquid is disposed on the mounting frame, and the collection device is connected to the recovery pipe.

[0008] By adopting the above technical solution, when the gas in the compressed air is transported through the gas pipeline, the excess heat is transferred to the water tank for recycling. At the same time, the liquid produced by the cooling and liquefaction of the gas enters the recovery pipe, and then the liquid in the recovery pipe is collected by the collection device, reducing the amount of liquefied liquid left in the gas pipeline, reducing the impact on heat transfer, and thus improving the heat transfer efficiency.

[0009] Optionally, the collection device includes a collection pipe and a collection bucket. The collection pipe is disposed inside the mounting frame and communicates with the recycling pipe. The collection bucket is disposed outside the mounting frame. The end of the collection pipe extends to the outside of the mounting frame and communicates with the collection bucket.

[0010] By adopting the above technical solution, the liquid in the recovery pipe enters the collection tank through the collection pipe, and is then collected and processed through the collection tank.

[0011] Optionally, the recovery pipe is provided with a second control valve for controlling the closure of the recovery pipe. The second control valve is located at one end of the recovery pipe near the gas supply pipe, and the second control valve and the first control valve are spaced apart.

[0012] By adopting the above technical solution, in the initial state, the first control valve is closed and the second control valve is open, and the generated liquid enters between the first control valve and the second control valve. When it is necessary to collect the liquid in the recovery pipe, the second control valve is closed to isolate the high-pressure air inside the recovery pipe and the gas transmission pipe. Then the first control valve is opened to transport the liquid in the recovery pipe to the collection pipe. At the same time, it can reduce the amount of high-pressure gas entering the collection pipe. In addition, it can realize centralized discharge treatment of liquid without stopping the machine.

[0013] Optionally, multiple recovery pipes are provided, and multiple recovery pipes are connected to multiple bends on the gas supply pipe. Multiple first control valves are arranged on the same straight line, and multiple second control valves are arranged on the same straight line. Each of the first and second control valves is provided with a first gear for controlling its closure. A first intermediate rod and a second intermediate rod are rotatably arranged within the mounting frame. The first intermediate rod is correspondingly arranged with multiple first control valves, and the second intermediate rod is correspondingly arranged with multiple second control valves. Each of the first and second intermediate rods is provided with a second gear, and the second gear meshes with the first gear.

[0014] By adopting the above technical solution, rotating the first intermediate rod and the second intermediate rod causes the first intermediate rod to drive the second gear to rotate, which in turn drives the first gear to rotate, thereby controlling the first control valve or the second control valve to recover the liquid in the recovery pipe.

[0015] Optionally, the mounting frame is provided with an adjustment device, which includes an adjustment disc, a handle, an intermediate component, and a limiting component. The adjustment disc is rotatably mounted on the mounting frame. Two sets of limiting components are provided, and the two sets of limiting components are respectively connected to a first intermediate rod and a second intermediate rod. The adjustment disc is rotatably mounted outside the mounting frame. The handle is eccentrically mounted on the adjustment disc for rotating the adjustment disc. The intermediate component is located inside the mounting frame. The rotation axis of the adjustment disc is connected through the intermediate component and the limiting component.

[0016] By adopting the above technical solution, rotating the adjusting plate causes the first intermediate rod and the second intermediate rod to rotate through the intermediate component and the limiting component, thereby adjusting the first control valve or the second control valve.

[0017] Optionally, the intermediate component includes an intermediate disk and intermediate gears. The intermediate disk is disposed between the first intermediate rod and the second intermediate rod. The intermediate gears are disposed on the side of the intermediate disk. Two intermediate gears are respectively disposed corresponding to the first intermediate rod and the second intermediate rod. The two intermediate gears are symmetrically arranged around the center of the intermediate disk. The rotation shaft of the adjusting disk is connected to the center of the intermediate disk. The intermediate disk is provided with a toothed groove. The toothed groove is arc-shaped. When the toothed groove rotates to different positions, it drives different intermediate gears to rotate.

[0018] By adopting the above technical solution, the toothed groove is set to be arc-shaped. When the intermediate disk rotates, it drives the toothed groove to mesh with the intermediate gear, thereby driving the intermediate gear to rotate. Through the meshing of the toothed groove with intermediate gears at different positions, the first intermediate rod and the second intermediate rod are driven to rotate respectively, thereby adjusting the opening and closing of the first control valve and the second control valve in sequence.

[0019] Optionally, the limiting component includes a worm gear and a worm. The worm gear is connected to the first intermediate rod, the worm is rotatably disposed within the mounting frame, and the end of the worm is connected to the rotation center of the intermediate gear. The worm and the worm gear mesh.

[0020] By adopting the above technical solution, the intermediate gear drives the worm gear to rotate, the worm gear rotates to drive the worm to rotate, and then drives the first intermediate rod to rotate. At the same time, the worm gear and worm have a self-locking property, which reduces the phenomenon of the first intermediate rod rotating on its own after the position of the first control valve is adjusted, thereby improving the stability of the first control valve.

[0021] Optionally, the collection bucket is equipped with a pressure relief valve for adjusting the pressure inside the collection bucket.

[0022] By adopting the above technical solution, the high-pressure gas in the collection tank is discharged through the pressure relief valve so that the collected liquid can be processed.

[0023] Optionally, a recovery section is provided at one end of the recovery pipe near the gas transmission pipe. The recovery section is funnel-shaped with openings at both ends. The larger opening end of the recovery section is connected to the bend in the gas transmission pipe, and the smaller opening end is connected to the recovery pipe.

[0024] By adopting the above technical solution, a recovery pipe is installed on the recovery pipe so that the liquid in the gas transmission pipe can enter the recovery pipe through the recovery part, thereby improving the liquid collection efficiency.

[0025] Optionally, the collection pipe is arranged along the direction of the arrangement of multiple recycling pipes, and the end of the collection pipe near the collection bucket is inclined in the direction toward the ground.

[0026] By adopting the above technical solution, the collection pipe is set at an angle so that the liquid can enter the collection tank for collection.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. During the transportation process, the high-temperature and high-pressure gas transfers its heat to the water tank through the gas delivery pipe. At the same time, the liquid generated enters the recovery pipe for recycling, reducing the impact of the liquid on gas transportation and thus improving the heat transfer efficiency.

[0036] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0037] This application discloses an energy-saving control device for an air compressor. (Refer to...) Figure 1 and Figure 2 The air compressor energy-saving control device includes an air compressor body 1 and a water tank 2 set on one side of the air compressor body 1. An air delivery pipe 11 is set on the air compressor body 1. The end of the air delivery pipe 11 away from the air compressor body 1 passes through the water tank 2. When compressed gas is transported through the air delivery pipe 11, heat is transferred to the water in the water tank 2, and this part of the heat is recovered and utilized.

[0038] Reference Figure 3 and Figure 4 The gas supply pipe 11 is arranged in a vertically bent shape inside the water tank 2, with the plane of the gas supply pipe 11 perpendicular to the ground. The water tank 2 is spaced apart from the ground. A mounting frame 21 is provided at the bottom of the water tank 2. A recovery pipe 3 is provided inside the mounting frame 21 to recover the liquid generated during the liquefaction of the gas during cooling. One end of the recovery pipe 3 is located inside the mounting frame 21, and the other end extends into the water tank 2 and connects with the bend at the bottom of the gas supply pipe 11. The recovery pipe 3 is arranged in a vertical direction. Multiple recovery pipes 3 are provided, and each of the multiple recovery pipes 3 is respectively arranged with multiple bends on the gas supply pipe 11 near the ground. A first control valve 4 is provided on the end of the recovery pipe 3 away from the water tank 2 to control the closure of the recovery pipe 3. In the initial state, the end of the recovery pipe 3 away from the water tank 2 is closed. After the compressed gas in the gas delivery pipe 11 is liquefied, the resulting liquid enters the recovery pipe 3 under its own gravity, reducing the amount of liquefied liquid remaining in the gas delivery pipe 11, so as to transport the gas and facilitate the transfer of heat to the water tank 2.

[0039] Reference Figure 3 and Figure 4A recovery section 31 is provided on the recovery pipe 3 near the gas transmission pipe 11. The recovery section 31 is funnel-shaped, with openings at both ends. The larger opening end of the recovery section 31 is connected to the gas transmission pipe 11, and the smaller opening end is connected to the recovery pipe 3. This allows the liquefied liquid in the gas transmission pipe 11 to enter the recovery pipe 3.

[0040] Reference Figure 3 and Figure 4 A collection device 5 is installed on the mounting frame 21. The collection device 5 includes a collection pipe 51 and a collection tank 52. The collection pipe 51 is located inside the mounting frame 21 and is arranged along the direction of the multiple recovery pipes 3. The recovery pipes 3 and the collection pipe 51 are connected. The collection tank 52 is located outside the mounting frame 21, with one end of the collection pipe 51 passing through the mounting frame 21 and connecting to the collection tank 52. When it is necessary to collect liquefied liquid, the first control valve 4 is opened to discharge the liquid in the recovery pipe 3 into the collection pipe 51, which then transports it to the collection tank 52. The end of the collection pipe 51 near the collection tank 52 is inclined towards the ground so that after the liquid enters the collection pipe 51, it enters the collection tank 52 through the collection pipe 51, improving the liquid collection efficiency.

[0041] Reference Figure 3 and Figure 4 A second control valve 6 is installed on the recovery pipe 3, located at the end of the recovery pipe 3 near the gas delivery pipe 11. In this embodiment, both the second control valve 6 and the first control valve 4 are ball valves, and the first control valve 4 and the second control valve 6 are spaced apart. Initially, the second control valve 6 is open, and the first control valve 4 is closed, allowing liquid to enter between the first control valve 4 and the second control valve 6. When liquid recovery is required, the second control valve 6 is closed, isolating the inside of the recovery pipe 3 from the inside of the gas delivery pipe 11. Then, the first control valve 4 is opened, discharging the liquid into the collection pipe 51, passing through the first control valve 4 and the second control valve 6 in sequence. During liquid discharge, the internal connection between the gas delivery pipe 11 and the collection pipe 51 is reduced, thereby reducing the amount of high-pressure gas from the gas delivery pipe 11 entering the collection pipe 51 for recovery. Simultaneously, during gas delivery, gas can be transported without stopping the machine, improving gas delivery efficiency.

[0042] Reference Figure 3 and Figure 4To facilitate adjustment of the first control valves 4 and second control valves 6 on the multiple recovery pipes 3, the multiple first control valves 4 are arranged in a straight line in the horizontal direction. The second control valves 6 are arranged in the same direction as the first control valves 4. A first gear 7 for controlling the closing of each of the first and second control valves 4 is provided on the outside. Rotating the first gear 7 can open the first and second control valves 4 and 6. A first intermediate rod 8 and a second intermediate rod 81 are rotatably arranged within the mounting frame 21. The first intermediate rod 8 corresponds to the first control valve 4, and the second intermediate rod 81 corresponds to the second control valve 6. The first intermediate rod 8 is arranged along the arrangement direction of the multiple first control valves 4, and the second intermediate rod 81 is arranged along the arrangement direction of the second control valves 6. A second gear 71 is provided on both the first intermediate rod 8 and the second intermediate rod 81, and multiple second gears 71 are corresponding to multiple first gears 7, with the second gears 71 meshing with the first gears 7. By rotating the first intermediate rod 8 or the second intermediate rod 81, the first control valves 4 and 6 can be adjusted respectively, improving the discharge efficiency of the liquefied liquid.

[0043] Reference Figure 4 and Figure 5 To facilitate the rotation of the first intermediate rod 8 and the second intermediate rod 81, an adjustment device 9 is provided on the mounting frame 21. The adjustment device 9 includes an adjustment disc 91, a handle 92, an intermediate component 93, and a limiting component 94. The adjustment disc 91 is rotatably mounted on the mounting frame 21. Two sets of limiting components 94 are provided, and the two sets of limiting components 94 are respectively connected to the first intermediate rod 8 and the second intermediate rod 81. The intermediate component 93 is located inside the mounting frame 21. The rotation shaft of the adjustment disc 91 is connected to the intermediate component 93, and the intermediate component 93 is connected to the limiting component 94. The handle 92 is eccentrically mounted on the adjustment disc 91. The adjustment disc 91 can be rotated by the handle 92, which in turn drives the first intermediate rod 8 and the second intermediate rod 81 to rotate through the intermediate component 93 and the limiting component 94, thereby controlling the discharge of liquid.

[0044] Reference Figure 5 and Figure 6 The intermediate component 93 includes an intermediate disk 931 and an intermediate gear 932. The intermediate disk 931 is disposed between the first intermediate rod 8 and the second intermediate rod 81, and is rotatably disposed within the mounting frame 21. The intermediate gear 932 is disposed on the side of the intermediate disk 931, and two intermediate gears 932 are respectively disposed corresponding to the first intermediate rod 8 and the second intermediate rod 81. The intermediate gear 932 is connected to the limiting component 94, and is symmetrically arranged around the center of the intermediate disk 931. The rotation axis of the adjusting disk 91 is connected to the center of the intermediate disk 931, that is, when the adjusting disk 91 rotates, it can drive the intermediate disk 931 to rotate. A toothed groove 933 is provided on the intermediate disk 931. The toothed groove 933 is arc-shaped and can mesh with the intermediate gear 932 to drive the intermediate gear 932 to rotate.

[0045] When the adjusting disc 91 is rotated, the toothed portion 933 rotates until it engages with the intermediate gear 932 on the second intermediate rod 81. Then, the limiting member 94 drives the second intermediate rod 81 to rotate, adjusting the second control valve 6. After the second control valve 6 is closed, the intermediate disc 931 continues to rotate, disengaging the toothed portion 933 and the intermediate gear 932 on the second intermediate rod 81. Then, the toothed portion 933 engages with the intermediate gear 932 on the first intermediate rod 8, thereby controlling the opening and closing of the first control valve 4. This sequentially drives the first control valve 4 and the second control valve 6 to rotate, discharging the liquid. After discharging, the intermediate disc 931 is rotated in the opposite direction.

[0046] Reference Figure 4 and Figure 5 The limiting member 94 is connected to the first intermediate rod 8 and the second intermediate rod 81 in the same way. The limiting member 94 includes a worm gear 941 and a worm 942. The worm gear 941 is connected to the end of the first intermediate rod 8, and the worm 942 meshes with the worm gear 941. The worm 942 is rotatably disposed within the mounting frame 21. The end of the worm 942 is connected to the rotation center of the intermediate gear 932. When the intermediate gear 932 rotates, it drives the first intermediate rod 8 to rotate through the worm 942 and the worm gear 941. The connection method of the limiting member 94 and the second intermediate rod 81 is the same as that of the first intermediate rod 8. At the same time, the worm gear 941 and the worm 942 have a self-locking mechanism, which reduces the phenomenon of rotation after the position of the first control valve 4 and the second control valve 6 is adjusted, thereby improving their stability.

[0047] Reference Figure 2 and Figure 3 A pressure relief valve 521 is installed on the collection tank 52. When the liquid in the recovery pipe 3 enters the collection pipe 51, some of the high-pressure gas inside will enter the collection tank 52 through the collection pipe 51, causing the pressure inside the collection tank 52 to rise. The pressure relief valve 521 can eliminate the pressure inside the collection tank 52 so that the collected liquid can be processed.

[0048] The implementation principle of this application is as follows: During the process of high-temperature and high-pressure gas being transported in the gas transmission pipe 11, the generated liquid enters the recovery pipe 3. Then, the regulating disc 91 is rotated. The regulating disc 91 drives the second intermediate rod 81 to rotate through the intermediate part 93 and the limiting part 94, thereby closing the second control valve 6. Continuing to rotate the regulating disc 91 drives the first intermediate rod 8 to rotate and open the first control valve 4, transferring the liquid in the recovery pipe 3 to the collection pipe 51. Then, the liquid enters the collection bucket 52 through the collection pipe 51 for collection, reducing the phenomenon of liquid interfering with gas transmission, thereby improving the heat transfer efficiency.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
