Description

Technical Field

[0001] This utility model belongs to the technical field of energy recovery and utilization equipment, and specifically relates to an air compressor heat utilization device. Background Technology

[0002] During operation, air compressors generate a large amount of high-temperature gas. To ensure that energy is not wasted, waste heat recovery and reuse devices are used to recover and reuse the heat.

[0003] While existing air compressor heat recovery devices can meet the basic requirements for waste heat recovery, the water in the tank is usually in a static state. This easily leads to different water temperatures in different areas, with water closer to the heat exchange tubes being warmer and water farther away being cooler. This not only results in the water in the tank not being fully heated, but also prevents the water in the tank from fully recovering the heat from the heat exchange tubes. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing an air compressor heat utilization device, which not only meets the basic requirement of recovering and utilizing the heat generated by the air compressor, but also enables the water in the water tank to be fully heated by agitating the water, thereby better meeting people's usage needs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an air compressor heat utilization device, including a filter box and a heat recovery water tank. A box cover is snapped onto the filter box, and multiple mounting frames are provided on the box cover, which are snapped onto the front and rear side walls and bottom wall of the filter box. Dust filter screens are provided on the mounting frames. An air inlet pipe is provided at one end of the filter box, and an air outlet pipe is provided at the other end of the filter box, passing through the side end of the heat recovery water tank. A spiral heat exchange tube connected to the air outlet pipe is provided inside the heat recovery water tank. An air pump connected to the other end of the heat exchange tube is also provided on the side wall of the water tank. A stirring shaft is rotatably provided on the side end of the heat recovery water tank, and stirring blades located inside the heat exchange tube are provided on the stirring shaft.

[0006] As a further improvement of this utility model, the heat recovery water tank is also equipped with an inlet pipe and a drain pipe, and a control valve is installed on the drain pipe.

[0007] As a further improvement of this utility model, a drive motor is also provided on the side of the heat recovery water tank, and a gear transmission assembly is provided between the output shaft of the drive motor and the stirring shaft.

[0008] As a further improvement of this utility model, the cover is snapped onto the top of the filter box, and the cover is also provided with fixing bolts for screwing the filter box in place. The filter box is provided with threaded fixing holes for screwing onto the fixing bolts.

[0009] As a further improvement of this utility model, the filter box is also provided with a first sealing ring that is misaligned with the threaded fixing hole.

[0010] As a further improvement of this utility model, a second sealing ring is provided on the outer side wall of the mounting frame, which abuts against the inner wall of the filter box.

[0011] As a further improvement of this utility model, a transparent observation window is also provided on the filter box, and a handle is also provided on the box cover. The transparent observation window facilitates observation of the internal condition of the filter box; the handle makes opening and closing more convenient; the inlet pipe and outlet pipe, together with the control valve, facilitate the filling and draining of the water tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, by setting up spiral heat exchange tubes, the hot air discharged from the air compressor flows inside the heat exchange tubes and exchanges heat with the water in the heat recovery water tank, thereby efficiently recovering the heat generated during the operation of the air compressor. Through the design of the stirring shaft and stirring blades, the water in the water tank can be stirred during the heat exchange process, making the heat distribution more uniform, thereby improving the heating efficiency and effect of the water.

[0014] Secondly, it allows for easy and flexible fixing of the cover and filter box, enabling users to easily remove the dust filter from the filter box for disassembly, cleaning, and reinstallation.

[0015] Thirdly, the installation of the first and second sealing rings ensures the airtightness of the filter box during operation, prevents gas leakage, and improves the safety and stability of equipment operation. Attached Figure Description

Detailed Implementation

[0022] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0023] like Figure 1 , 3 As shown in Figure 4, an air compressor heat recovery device includes a filter box 101 and a heat recovery water tank 102. The filter box 101 is located on top of the heat recovery tank. A cover 103 is snapped onto the filter box 101. Multiple mounting frames 104 are attached to the cover 103 and snapped onto the front and rear side walls and bottom wall of the filter box 101. Dust filters 105 are mounted on the mounting frames 104. An air inlet pipe 106 is provided at one end of the filter box 101, and an air outlet pipe 107 is provided at the other end of the filter box 101, passing through the side end of the heat recovery water tank 102. A spiral heat exchange tube 108 connected to the air outlet pipe 107 is provided inside the heat recovery water tank 102. A vacuum pump 110 connected to the other end of the heat exchange tube 108 is also provided on the side wall of the water tank. A stirring shaft 111 is rotatably mounted on the side end of the heat recovery water tank via a bearing 116. Stirring blades 112 located inside the heat exchange tube 108 are provided on the stirring shaft 111. The inner wall of the heat recovery water tank 102 is also provided with fixing rods 109 for fixing the heat exchange tubes 108.

[0024] The heat recovery water tank is also equipped with a temperature sensor 117, which allows for convenient detection of the water's heating temperature, enabling timely water replacement. Multiple mounting frames 104 and dust filters 105 are included. Along the flow direction of the high-temperature gas, the mesh size of the multiple dust filters 105 decreases sequentially, thus filtering dust from the high-temperature gas in stages for more thorough purification.

[0025] like Figure 2 As shown, the heat recovery water tank 102 is also equipped with an inlet pipe 113 and a drain pipe 114, and a control valve 115 is installed on the drain pipe 114.

[0026] like Figure 1 As shown, a drive motor 201 is also provided on the side of the heat recovery water tank 102, and a gear transmission assembly 202 is provided between the output shaft of the drive motor 201 and the stirring shaft 111.

[0027] like Figure 1 As shown, the cover 103 is snapped onto the top of the filter box 101. The cover 103 is also provided with a fixing bolt 301 for screwing the filter box 101. The filter box 101 is provided with a threaded fixing hole for screwing the fixing bolt 301.

[0028] The hot gas generated by the air compressor enters the filter box 101 through the intake pipe 106. When the gas passes through the filter box 101, the dust filter 105 installed on the mounting frame 104 filters the dust and impurities in the gas to ensure that the gas entering the subsequent system is clean and to prevent the heat exchange tube 108 from being easily blocked.

[0029] The filtered hot gas enters the spiral heat exchange tube 108 through the gas outlet 107. The heat exchange tube 108 is located inside the heat recovery water tank 102. The hot gas flows in the heat exchange tube 108 and exchanges heat with the water in the heat recovery water tank 102, thereby transferring heat to the water. In order to make the heat distribution more uniform and improve the heat exchange efficiency, the drive motor 201 drives the stirring shaft 111 to rotate through the gear transmission assembly 202. The stirring blades 112 on the stirring shaft 111 agitate the water in the tank.

[0030] The control valve 115 can be opened to discharge the heated water into the heat recovery water tank 102 through the drain pipe 114. Then, the control valve 115 can be closed, and cold water can be added back into the heat recovery water tank 102 through the inlet pipe 113 to continue the heat recovery treatment of the high-temperature gas generated during the operation of the air compressor.

[0031] After heat exchange, the gas is connected to the vacuum pump 110 at the other end of the heat exchange tube 108. The vacuum pump 110 discharges the cooled gas from the system, ensuring the continuity and stability of the heat exchange process.

[0032] According to another embodiment of the present invention, such as Figure 1 As shown, the filter box 101 is also provided with a first sealing ring 302 that is misaligned with the threaded fixing hole. The first sealing ring 302 can enhance the sealing performance at the connection between the box cover 103 and the filter box 101.

[0033] According to another embodiment of the present invention, such as Figure 3 As shown, a second sealing ring 303 is provided on the outer side wall of the mounting frame 104, which abuts against the inner wall of the filter box 101. The second sealing ring 303 can enhance the sealing performance at the connection between the mounting frame 104 and the side wall of the filter box 101.

[0034] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the filter box 101 is also equipped with a transparent observation window 304, and the cover 103 is also equipped with a handle 305. The condition of the dust filter 105 inside the filter box 101 can be observed at any time through the transparent observation window 304 to determine whether it needs to be cleaned or replaced.

[0035] When it is necessary to clean the dust filter 105, simply loosen the fixing bolts 301, open the cover 103, and remove the mounting frame 104 from the filter box 101 to easily clean or replace the dust filter 105.

[0036] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
