Description

Technical Field

[0001] The invention relates to the technical field of air compressor waste heat recovery, and in particular to an air compressor waste heat recovery and reuse device. Background Art

[0002] Air compressors are basic products of industrial modernization. The commonly mentioned electrical and automation have the meaning of full pneumatics, and air compressors provide air source power. They are the core equipment of the pneumatic system and the main body of the electromechanical air source device. They are devices that convert the original mechanical energy into gas pressure energy. They are air pressure generating devices for compressed air. Screw compressors, as a type of air compressor, generate a lot of heat when working. The heat is carried out of the body through the lubricating oil. Generally, waste heat recovery devices are used to recover the heat to avoid a large amount of heat being dissipated into the air and wasted.

[0003] Existing air compressor waste heat recovery and reuse devices usually insert the circulation exchange tube into the water, so as to use the waste heat to heat the water source, thereby realizing the function of waste heat recovery of the air compressor. However, after long-term use of the existing device, a large amount of scale often adheres to the outer surface of the circulation exchange tube, thereby wrapping the circulation exchange tube, thereby affecting the recovery of heat by the water source, making the waste heat recovery efficiency worse, and reducing the recovery efficiency of the air compressor waste heat recovery and reuse device. To this end, we propose an air compressor waste heat recovery and reuse device.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing air compressor waste heat recovery and reuse devices on the market, and even if they can be solved, they need to be solved through external tools, which cannot achieve the desired effect.

The interiors of the two fixed frames 2113 are both provided with rack rings 2114, and the outer surfaces of the two rack rings 2114 Both are provided with teeth, one of which is a rack ring 2114 meshing with the rotating gear 2112, a water pump 2115 is fixedly installed at the bottom of the mobile frame 2107, and the water pump 2115 is connected to a hose 2116, and two fixed blocks 2117 are fixedly installed on the inner walls of the two rack rings 2114, and a high-pressure nozzle 2118 is fixedly installed on the fixed block 2117, and the other end of the hose 2116 is connected to the water inlet end of the high-pressure nozzle 2118; the high-pressure flushing unit 21 enables the device to perform mobile and rotating high-pressure flushing on the scale attached to the outer surface of the exchange tube body 13, so as to avoid the accumulation of scale on the outer surface of the exchange tube body 13, which affects the heat absorption of the water source to the inside of the exchange tube body 13, and increases the waste heat recovery effect of the device;

[0039] A slide bar 2119 is vertically fixedly installed in the connecting frame 2101. The slide bar 2119 is slidably connected to the moving frame 2107. The slide bar 2119 guides the moving track of the moving frame 2107 to ensure the stability of the movement of the moving frame 2107.

[0040] A slider 2120 is fixedly installed on one side of the rack plate 2111, and a slide groove 2121 is provided on the inner wall of the mobile frame 2107. The slider 2120 is slidably connected in the slide groove 2121. The slider 2120 is in a T-shaped structure, and the slide groove 2121 matches the slider 2120. The slider 2120 and the slide groove 2121 play a role in limiting the moving track of the rack plate 2111, preventing the rack plate 2111 from deviating from the moving track when moving, and ensuring the stability of the movement of the rack plate 2111.

[0041] The two corresponding ends of the two fixing frames 2113 are fixedly connected by two fixing bolts 2122. The installation of the fixing bolts 2122 fixes the two fixing frames 2113 into a circular ring structure, which is convenient for workers to put the two fixing frames 2113 on the exchange tube body 13 and to clean the scale of the exchange tube body 13.

[0042] Three pulleys 2123 are fixedly installed on the outer circumferential surfaces of the two rack rings 2114, and slide rails 2124 are provided on the inner walls of the two fixed frames 2113.

[0043] During use, the worker opens the valve 15, and the water inside the water tank body 12 is discharged through the outlet pipe 14. Then the worker places the connecting frame 2101 in the water tank body 12, and at the same time makes the exchange tube body 13 located in the two fixing frames 2113. The two fixing frames 2113 are fixedly connected by the fixing bolts 2122, and the fixing frames 2113 are sleeved on the exchange tube body 13. When the device uses the high-pressure flushing unit 21 to clean the scale on the outer surface of the exchange tube body 13, the worker connects the water pump 2115 with the water source, and turns on the rotating motor 2106 and the water pump 2115 through the external remote control device. The rotating motor 2106 drives the connecting wheel 2104 to rotate, and the connecting wheel 2104 drives another connecting wheel 2104 to rotate through the belt 2105.

When the connecting disk 2110 rotates, the rack plate 2111 cooperates with the rotating gear 2112 to periodically rotate forward and reversely. The rotating gear 2112 drives the rack ring 2114 meshing with it to rotate. The rack ring 2114 rotates around the exchange tube body 13 while moving upward along the exchange tube body 13 to prevent the hose 2116 from being entangled on the exchange tube body 13. When the rack ring 2114 rotates and moves, the water source is sprayed on the outer surface of the exchange tube body 13 through the hose 2116 and the high-pressure nozzle 2118 by the water pump 2115, thereby flushing the scale on the outer surface of the exchange tube body 13 to prevent the scale from accumulating on the outer surface of the exchange tube body 13 and affecting the absorption of heat inside the exchange tube body 13 by the water source.

[0044] The flushing mechanism 2 further includes an acid flushing unit 22, which is located inside the high-pressure flushing unit 21. The high-pressure flushing unit 21 is used in conjunction with the acid flushing unit 22, and the acid flushing unit 22 is used to dissolve and separate scale.

[0045] The acid washing unit 22 includes a storage box 2201, which is mounted on the top of the mobile frame 2107. The storage box 2201 is slidably connected to a piston frame 2202. A wedge block 2203 is vertically mounted on the inner wall of the connecting frame 2101. One end of the piston frame 2202 close to the wedge block 2203 contacts the inclined surface of the wedge block 2203 through a contact rod. The storage box 2201 is connected to one end of the conveying pipe 2204. Two mounting blocks 2205 are fixedly mounted on the inner walls of the two rack rings 2114. The mounting blocks 2203 are fixedly mounted on the inner walls of the two rack rings 2114. 05 is fixedly installed with a nozzle 2206, the other end of the delivery pipe 2204 penetrates into the mounting block 2205 and is connected with the water inlet end of the nozzle 2206, the inner walls of the two rack rings 2114 are fixedly installed with two mounting brackets 2207, and the side surface of the mounting brackets 2207 away from the rack ring 2114 is fixedly installed with two groups of connecting springs 2208, and the number of each group of connecting springs 2208 is two, and the end of the connecting spring 2208 away from the mounting bracket 2207 is fixedly connected to the fixing plate 2209, and the fixing plate 2209 is away from the connecting A rotating wheel 2210 is fixedly installed on one side of the spring 2208, and the rotating wheel 2210 is slidably connected to the outer wall of the exchange tube body 13. A pressure sensor 2211 is fixedly installed on the side of the mounting frame 2207 away from the rack ring 2114, and the detection end of the pressure sensor 2211 is in contact with the side of the fixing plate 2209 away from the rotating wheel 2210. An electric push rod 2212 is fixedly installed on the nozzle 2206, and a retaining frame 2213 is fixedly installed on the telescopic end of the electric push rod 2212. The retaining frame 2213 is close to the nozzle 220 One side of the nozzle 2206 contacts the outer surface of the nozzle 2206. The outer surface of the nozzle 2206 is provided with water outlets arranged at equal distances. The size of the water flow is adjusted by changing the shielding of the water outlet by the baffle 2213. The four pressure sensors 2211 are electrically connected to the four electric push rods 2212 in a one-to-one correspondence. The acid flushing unit 22 sprays the acid solution on the outer surface of the exchange tube body 13 to dissolve the scale on the outer surface of the exchange tube body 13, so that the device reduces the adhesion of the scale before high-pressure flushing, thereby facilitating the shedding of the scale.

[0046] Two groups of telescopic columns 2214 are fixedly installed on one side of the mounting frame 2207 away from the rack ring 2114, and each group of telescopic columns 2214 has two telescopic columns. The telescopic columns 2214 are inserted into the connecting spring (2208), and the telescopic ends of the telescopic columns 2214 are fixedly connected to the side of the fixed plate 2209 away from the rotating wheel 2210; the telescopic columns 2214 limit the moving track of the fixed plate 2209, avoid the phenomenon of the fixed plate 2209 deviating from the moving track when moving, and ensure the stability of the movement of the fixed plate 2209;

[0047] During use, a worker adds an acid solution into the storage box 2201. During the movement of the high-pressure flushing unit 21, the wedge block 2203 squeezes the piston frame 2202, and squeezes the acid solution inside the storage box 2201 into the delivery pipe 2204, so that the acid solution passes through the nozzle 2206 and is sprayed on the outer surface of the exchange tube body 13, and the scale is dissolved by the acid solution. At the same time, during the spraying process, due to the uneven distribution of scale, when encountering thick scale, the scale will squeeze the rotating wheel 2210, causing the rotating wheel 2210 to squeeze the connecting spring 2208, compressing the connecting spring 2208, and the pressure sensor 2211 is subjected to pressure, and the pressure indication of the pressure sensor 2211 increases. The pressure sensor 2211 controls the electric push rod 2212 to contract, and uses the power provided by the pressure sensor 2211 to drive the retaining frame 2213 to move upward, so that the exposed part of the water outlet of the nozzle 2206 increases, thereby increasing the spraying amount of the acidic solution, so that when the device encounters thicker scale, the spraying flow rate of the acidic solution is increased. Similarly, when the thickness of the scale is thin, the pressure sensor 2211 controls the retaining frame 2213 to move downward, reduce the spraying flow rate of the acidic solution, reduce the adhesion of the scale, and facilitate the high-pressure flushing unit 21 to clean the scale.

[0048] A knocking mechanism 3 is provided inside the high-pressure flushing unit 21. The knocking mechanism 3 is used in conjunction with the flushing mechanism 2. The knocking mechanism 3 is used to knock the scale on the outer surface of the exchange tube body 13 to remove it.

[0049] The knocking mechanism 3 includes a placement rack 301, which is fixedly mounted on the upper part of the mobile rack 2107. An air gun box 302 is fixedly mounted in the placement rack 301. A rubber pad 303 is fixedly mounted on one side of the air gun box 302. The rubber pad 303 has a good extension effect. A magnet 304 is fixedly mounted on the rubber pad 303. A hydraulic rod 305 is fixedly mounted on the inner wall of the placement rack 301. An electromagnet 306 is fixedly mounted on the telescopic end of the hydraulic rod 305. The electromagnet 306 can adsorb and disconnect the magnet 304 by turning on and off the power supply. A rectangular plate 307 is fixedly mounted on the inner wall of the placement rack 301. A rubber hammer 308 is slidably connected to the rectangular plate 307. The rubber hammer 308 is close to the air gun box 302. A moving block 309 is fixedly installed at one end, and two groups of buffer springs 310 are fixedly installed on one side surface where the moving block 309 is connected to the rubber hammer 308, and the number of each group of buffer springs 310 is two. One end of the buffer spring 310 is fixedly connected to the rectangular plate 307, and two groups of dampers 311 are fixedly installed between the rectangular plate 307 and the moving block 309. The number of each group of dampers 311 is two, and the dampers 311 are penetrated in the buffer spring 310; the knocking mechanism 3 knocks the scale attached to the outer surface of the exchange tube body 13 in the form of an air cannon, and the larger pieces of scale are shattered and decomposed, further reducing the adhesion of the scale, so that the flushing mechanism 2 can better clean the scale, ensuring that the device has a good cleaning effect on the exchange tube body 13;

[0050] During the movement of the high-pressure flushing unit 21, the hydraulic rod 305 is used to drive the electromagnet 306 to move toward the magnet 304. When the electromagnet 306 contacts the magnet 304, the electromagnet 306 is powered on, and the magnet 304 is adsorbed on the electromagnet 306 by the attraction between the electromagnet 306 and the magnet 304. Then the hydraulic rod 305 contracts, so that the hydraulic rod 305 cooperates with the electromagnet 306 and the magnet 304 to drive the rubber pad 303 to stretch. When the electromagnet 306 returns to its original position, the power supply of the electromagnet 306 is disconnected, and the magnet 304 is driven to move to its original position under the action of the elastic force of the rubber pad 303. During the movement of the rubber pad 303, the gas inside the gas gun box 302 is compressed and pushed. According to the Bernoulli principle, the gas gun box 302 will emit a ring-shaped airflow to bombard the moving block 309, so that the moving block 309 drives the rubber hammer 308 to hammer the outer surface of the exchange tube body 13, thereby hammering and splitting the larger scale on the outer surface of the exchange tube body 13, which is convenient for cleaning the scale. While hammering, the buffer spring 310 and the damper 311 are used to reduce the impact force of the rubber hammer 308 on the exchange tube body 13 to avoid excessive impact force and deformation of the exchange tube body 13.
