Description

Technical Field

[0001] This invention relates to the field of forced-air hot dryer technology, specifically a multi-functional compressed forced-air hot dryer. Background Technology

[0002] In order to save energy, in addition to the simpler heatless adsorption dryer, micro-heat adsorption dryer, and combined dryer that simply connects a refrigerated dryer and an adsorption dryer, there are now many other models on the market, such as the compression heat adsorption dryer that uses the high exhaust temperature of the air compressor, and the blower adsorption dryer that uses a blower to heat the ambient air to reduce the amount of regeneration gas used.

[0003] Existing technologies such as heatless adsorption dryers, micro-heat adsorption dryers, combined dryers, and compression heat dryers require high air consumption. Once the structural dimensions are determined, the processing air volume of the equipment is fixed. The advantage of blower adsorption dryers is that they do not consume their own drying air volume (or only consume a very small amount of drying air during the cold blowing stage). As long as it does not exceed its maximum processing air volume, its processing air volume can be changed. However, the disadvantage is that the equipment requires a low inlet air temperature, usually below 38°C, to obtain dry gas with a low dew point. Therefore, it cannot utilize the high outlet air temperature of the air compressor, which wastes the energy of the air compressor system itself. Although compression heat dryers can utilize the high outlet air temperature of the air compressor to reduce energy waste, they also have the disadvantages of relatively fixed processing air volume, working pressure, and equipment load. Once any of these parameters changes, it will affect the performance of the equipment, resulting in certain usage defects. Summary of the Invention

[0021] By adopting the above technical solution, compressed air will only enter the filter box after the movable rod moves to seal it, thus avoiding compressed air leakage.

[0022] Compared with the prior art, the beneficial effects of the present invention are: the multi-functional compressed air hot dryer can achieve multiple functions by increasing or decreasing the number of adsorption towers (the corresponding valves and pipes can be easily added or removed at the reserved connection points), achieving the most equipment functions with the least amount of money and the smallest footprint, maximizing the utilization of the air compressor's waste heat and reducing the energy consumption of various equipment. 1. This invention utilizes the advantages of various drying equipment to meet different user gas volume requirements. It leverages off-peak electricity, taking advantage of cheaper electricity prices at night, and uses high-temperature compressed air generated by an air compressor to preheat and regenerate the adsorbent in the adsorption tower. When the heating and regeneration are insufficient, a forced-air adsorption dryer is used for deep heating and regeneration (this can be omitted if there is sufficient heat of compression). Depending on equipment needs, zero-air-consumption forced-air cold-blowing regeneration can be activated (this can be omitted if natural cooling time is sufficient). To avoid wasting heat energy, a heat recovery unit is added before the first cooler. The recovered heat energy can be used for domestic water supply, maximizing energy and cost savings. During hot gas adsorption, the gas enters through the inlet pipe, which is equipped with valves. When the second adsorption tower needs regeneration, the corresponding valves on different pipes are controlled to ensure a connection between the inlet pipe and the second adsorption tower, allowing compressed air to flow freely. The gas enters the third adsorption tower through a section of pipe twelve (red arrows in the attached diagram indicate the reverse direction of compression heat and regeneration gas flow). When regenerating the second adsorption tower, the blower blows out gas, which is cooled by the second cooler. The cold gas then enters the second adsorption tower through pipes eight and six for cold blowing regeneration (blue arrows in the attached diagram indicate the direction of cold blowing gas flow). The cold blowing gas then passes through pipes five and fifteen. When regenerating the second adsorption tower by heating, the blower blows out gas, which is heated by the heater (orange arrows in the attached diagram indicate the direction of heating gas flow). The heated gas can enter the second adsorption tower through pipes fifteen and five for heating regeneration. The heated gas can then be discharged through pipes six and seven. All the outlet pipes connected to the adsorption towers are equipped with check valves to prevent backflow of gas after discharge. By controlling the valves on different pipes, different adsorption towers can be adsorbed, regenerated, and prepared for use. 2. When the third adsorption tower is in use, valve two is open, valve one is closed, and valves three and six are closed, allowing compressed air to enter the third adsorption tower. When the second adsorption tower is in use, valves two, four, five, and six are closed, while valve one allows compressed air to enter the second adsorption tower. When the first adsorption tower is in use, valves one and two are closed, the valve on pipe eleven is closed, and valve six is ​​open, allowing compressed air to enter the first adsorption tower. When the compressed air enters the second adsorption tower, it flows from left to right to pipe twelfth. The compressed air can push the sealing block to move, causing the sealing ring to leave the mounting ring. This allows the movable rod to move and stretch the telescopic spring. After the movable rod moves a certain distance, it can push the sealing ring to move. After the sealing ring moves, it can compress the support spring. The elastic potential energy of the support spring is greater than that of the telescopic spring. Then, under the action of compressed air, the sealing ring separates from the fixed ring, and the compressed air can enter the filter box. The glass fiber filter layer on the mounting frame can filter oil and impurities in the compressed air, preventing oil and impurities from entering the adsorption tower and affecting the service life of the adsorbent and the dehumidification effect. While the movable rod moves, it can drive the sealing plate to move through the movable frame. The sealing plate can seal the through groove, making the filter box sealed. When the compressed air stops entering, the telescopic spring will reset the movable rod, which in turn will reset the sealing plate. At this time, the mounting frame can be disassembled through the through groove, and the glass fiber filter layer can be disassembled and cleaned. When switching the working state of different adsorption towers, the corresponding filter structure can filter the compressed air, and the filter box without compressed air can be automatically opened for easy cleaning by the operator. 3. When compressed air enters, it first moves the sealing block, causing the movable rod to move. After the movable rod moves, the push rod on the movable ring comes into contact with the movable ring. Then, the movable rod continues to move, pushing the movable ring to move, which in turn drives the connecting rod to rotate. This causes the mounting block to move, stretching the return spring and preventing the positioning rod from contacting the movable ring. At this point, the sealing ring loses its limit, and the compressed air can push the sealing ring to move. Only after the movable rod moves and seals the filter box will the compressed air enter the filter box, thus preventing compressed air leakage and waste. Attached Figure Description

[0027] Example 1: As Figures 1-2As shown, this invention utilizes the advantages of various drying equipment to meet different user gas volume requirements. It leverages off-peak electricity, taking advantage of cheaper electricity prices at night, and uses high-temperature compressed air generated by an air compressor to preheat and regenerate the adsorbent in the adsorption tower. When the heating and regeneration are insufficient, a blower-type adsorption dryer is used for deep heating and regeneration. Depending on equipment needs, zero-air-consumption blower cold-blowing regeneration can be activated. To avoid wasting heat energy, a heat recovery unit 105 is added before the first cooler 106. The recovered heat energy can be used for domestic water supply, maximizing energy and cost savings. During hot gas adsorption, the gas enters through the inlet pipe 103, which is equipped with valves. When the second adsorption tower 101 needs regeneration, the corresponding valves on different pipes are controlled, allowing the inlet pipe 103 to connect with pipe 108, and compressed air can then pass through pipe 101.

Afterward, the cold blowing airflow enters the second adsorption tower 101 through pipe 5 111 and pipe 15 121. When the second adsorption tower 101 is heated for regeneration, the airflow blown out by the blower 124 is heated by the heater 122. The heated airflow can enter the second adsorption tower 101 through pipe 15 121 and pipe 5 111 for heating regeneration. Afterward, the heated airflow can be discharged through pipe 6 112 and pipe 7 113. All the outlet pipes connected to the adsorption towers are equipped with check valves to prevent gas backflow after discharge. By controlling the valves on different pipes, different adsorption towers can be adsorbed, regenerated, and prepared for use.

The filter box 201 has an installation frame 202 inside, and a glass fiber filter layer 203 is fixedly installed inside the installation frame 202. Support bars 204 are symmetrically installed on both sides of the installation frame 202 at the top inside the filter box 201. Several installation bars 205 are symmetrically installed on the upper outer side of the installation frame 202. Several installation grooves 206 are opened on the side of the two support bars 204 that are close to each other. The installation bars 205 are detachably connected to the installation grooves 206. A positioning bar 207 is fixedly installed on one side of the bottom inside the filter box 201. A fixing bracket 208 is fixedly installed on one side of the inside of the filter box 201. A movable rod 209 is slidably connected to the lower interior of the fixed frame 208, and a telescopic spring 210 is sleeved on the outer side of the movable rod 209. A fixed block 211 is fixedly installed at one end of the movable rod 209. At the same time, the two ends of the telescopic spring 210 are fixedly connected to the fixed block 211 and the fixed frame 208 respectively. A fixed ring 212 is fixedly installed inside the pipe 118 on one side of the filter box 201. A sealing ring 213 is slidably connected to the outer side of the movable rod 209, and the sealing ring 213 abuts against the fixed ring 212. A support spring 214 is fixedly installed on one side of the sealing ring 213, and the end of the support spring 214 away from the sealing ring 213 is fixedly connected to the fixed frame 208. Inside pipe 118, an installation ring 217 is fixedly installed on one side of the fixed ring 212, and a sealing block 215 is fixedly installed on the other end of the movable rod 209. A sealing ring 216 is fixedly installed on one side of the sealing block 215, and the sealing ring 216 abuts against the installation ring 217. A movable frame 218 is fixedly installed on one side of the fixed block 211, and a sealing plate 219 is fixedly installed at the bottom of the movable frame 218. A movable groove 220 is opened at the bottom of the filter box 201, and the sealing plate 219 is slidably connected to the movable groove 220. A sliding groove is opened through the bottom of the filter box 201 above the movable groove 220, and the movable frame 218 is slidably connected to the sliding groove. A through groove 221 is opened through the bottom of the filter box 201 below the mounting frame 202, and a groove is opened at the bottom of the mounting frame 202.

[0029] Example 2: Figures 1-8As shown, when the third adsorption tower 102 is in use, valve 2 126 is open, valve 1 125 is closed, and valves 3 127 and 6 130 are closed, allowing compressed airflow to enter the third adsorption tower 102. When the second adsorption tower 101 is in use, valves 2 126, 4 128, 5 129, and 6 130 are closed, and valve 1 125 allows compressed airflow to enter the second adsorption tower 101. When the first adsorption tower 1 is in use, valves 1 125 and 2 126 are closed, and pipe 11 11... Valve 7 is closed, and valve 6 (130) is opened, allowing compressed air to enter the first adsorption tower 1. As the compressed air enters the second adsorption tower 101, it flows from left to right towards pipe 118. The compressed air can push the sealing block 215 to move, causing the sealing ring 216 to move away from the mounting ring 217. This allows the movable rod 209 to move and stretch the telescopic spring 210. After the movable rod 209 moves a certain distance, it can push the sealing ring 213 to move. After the sealing ring 213 moves, it can compress the support spring 214. The elastic potential energy of the support spring 214 is greater than that of the extension spring 210. Under the action of compressed air, the sealing ring 213 is disengaged from the fixed ring 212, allowing the compressed air to enter the filter box 201. The glass fiber filter layer 203 on the mounting frame 202 filters out oil and impurities in the compressed air, preventing them from entering the adsorption tower and affecting the service life of the adsorbent and the dehumidification effect. While the movable rod 209 moves, it can drive the sealing plate 219 to move via the movable frame 218. The sealing plate 219 can seal the through groove 221, thus sealing the filter box 201. When the compressed air stops entering, the extension spring 210 resets the movable rod 209, which in turn resets the sealing plate 219. At this time, the mounting frame 202 can be disassembled through the through groove 221, allowing the glass fiber filter layer 203 to be disassembled and cleaned. This ensures that when switching between different adsorption tower operating states, the corresponding filter structure can filter the compressed air, while the filter box 201 without compressed air can automatically open for easy cleaning by the operator.

A positioning rod 223 is slidably connected to one side of the inner side of each of the four mounting brackets 222. A mounting block 224 is fixedly mounted on one end of the positioning rod 223. A return spring 225 is sleeved on the outer side of the positioning rod 223 on one side of the mounting bracket 222. The two ends of the return spring 225 are fixedly connected to the mounting bracket 222 and the mounting block 224, respectively. A fixing rod 226 is fixedly mounted on one side of each of the four mounting brackets 222. A movable ring 227 is slidably connected to the outer side of the four fixing rods 226. Four connecting rods 228 are symmetrically hinged to the inner side of the movable ring 227. The end of the connecting rod 228 away from the movable ring 227 is hinged to the mounting block 224. A moving ring 229 is fixedly mounted on the outer side of the movable rod 209 on one side of the movable ring 227. Four push rods 230 are fixedly mounted on the outer circumference of the moving ring 229.

[0031] Example 3: Figures 8-9 As shown, when compressed air enters, it first moves the sealing block 215, causing the movable rod 209 to move. After the movable rod 209 moves, the push rod 230 on the movable ring 229 abuts against the movable ring 227. Then, the movable rod 209 continues to move, which can push the movable ring 227 to move, causing the connecting rod 228 to rotate, which in turn can move the mounting block 224, causing the positioning rod 223 to move and stretch the return spring 225, so that the positioning rod 223 no longer abuts against the movable ring 229. At this time, the sealing ring 213 can lose its limit, and the compressed air can push the sealing ring 213 to move, causing the movable rod 209 to move and seal the filter box 201 before the compressed air enters the filter box 201, which can avoid compressed air leakage and waste.

[0032] Working principle: When using this multi-functional compressed air hot dryer, firstly, according to... Figures 1-9As shown, the advantages of various drying equipment can be utilized to meet different user gas volume requirements. Peak and off-peak electricity rates can be used, particularly at night when electricity prices are lower. High-temperature compressed air generated by an air compressor is used to preheat and regenerate the adsorbent in the adsorption tower. If the heating and regeneration are insufficient, a blower-type adsorption dryer is used for deep heating and regeneration. Depending on equipment needs, zero-air-consumption blower cold-blowing regeneration can be activated. To avoid wasting heat energy, a heat recovery unit 105 is added before the first cooler 106. The recovered heat energy can be used for domestic water supply, maximizing energy and cost savings. During hot gas adsorption, the gas enters through the inlet pipe 103, which is equipped with valves. When the second adsorption tower 101 needs regeneration, the corresponding valves on different pipes are controlled to ensure proper regeneration. The intake pipe 103 and the second pipe 108 are connected. Compressed air can enter the third adsorption tower 102 through a section of the twelfth pipe 118. When the second adsorption tower 101 is regenerated, the blower 124 blows out airflow, which is cooled by the second cooler 123. Then the cold airflow enters the second adsorption tower 101 through the eighth pipe 114 and the sixth pipe 112 for cold blowing regeneration. After that, the cold blowing airflow passes through the fifth pipe 111 and the fifteenth pipe 121. When the second adsorption tower 101 is heated for regeneration, the airflow blown out by the blower 124 is heated by the heater 122. The heated airflow can enter the second adsorption tower 101 through the fifteenth pipe 121 and the fifth pipe 111 for heated regeneration. After that, the heated airflow can be discharged through the sixth pipe 112 and the seventh pipe 113. When the third adsorption tower 102 is in use, valve 2 126 is open, valve 1 125 is closed, and valves 3 127 and 6 130 are closed, allowing compressed airflow to enter the third adsorption tower 102. When the second adsorption tower 101 is in use, valves 2 126, 4 128, 5 129, and 6 130 are closed, and valve 1 125 allows compressed airflow to enter the second adsorption tower 101. When the first adsorption tower 1 is in use, valves 1 125 and 2 126 are closed, the valve on pipe 11 117 is closed, and valve 6 130 is open, allowing compressed airflow to enter the first adsorption tower 1. When the compressed airflow enters the second adsorption tower 101, it flows from left to right towards pipe 12 1. 18. Compressed air can move the sealing block 215, causing the sealing ring 216 to move away from the mounting ring 217. This allows the movable rod 209 to move and stretch the telescopic spring 210. After the movable rod 209 moves a certain distance, it can push the sealing ring 213 to move. After the sealing ring 213 moves, it can compress the support spring 214. The elastic potential energy of the support spring 214 is greater than that of the telescopic spring 210. Then, under the action of compressed air, the sealing ring 213 moves away from the fixed ring 212. The compressed air can then enter the filter box 201. The glass fiber filter layer 203 on the mounting frame 202 can filter out oil and impurities in the compressed air, preventing oil and impurities from entering the adsorption tower and affecting the service life of the adsorbent. To improve dehumidification, the movable rod 209 moves while simultaneously moving via the movable frame 218, which in turn moves the sealing plate 219. The sealing plate 219 seals the through-slot 221, thus sealing the filter box 201. When compressed air stops entering, the telescopic spring 210 resets the movable rod 209, which in turn resets the sealing plate 219. At this point, the mounting frame 202 can be disassembled via the through-slot 221, allowing for the removal and cleaning of the glass fiber filter layer 203. This ensures that when switching between different adsorption tower operating states, the corresponding filter structure can filter compressed air, while the filter box 201 without compressed air can automatically open for easy cleaning by operators. When compressed air enters, it first carries... The moving sealing block 215 moves, causing the movable rod 209 to move. After the movable rod 209 moves, the push rod 230 on the movable ring 229 abuts against the movable ring 227. Then, the movable rod 209 continues to move, which can push the movable ring 227 to move, thereby driving the connecting rod 228 to rotate, which in turn drives the mounting block 224 to move, causing the positioning rod 223 to move and stretch the return spring 225, so that the positioning rod 223 no longer abuts against the movable ring 229. At this time, the sealing ring 213 can lose its limit, and compressed air can push the sealing ring 213 to move, so that the movable rod 209 moves to seal the filter box 201. Only then will the compressed air enter the filter box 201, which can avoid compressed air leakage and waste.
