Description

Technical Field

[0001] The present invention relates to the technical field of air treatment, and in particular to a pretreatment device for air separation and a treatment method thereof. Background Art

[0002] An air separation unit is a set of industrial equipment used to separate the various gas components in the air and produce oxygen, nitrogen, argon and other gases as air components. The most commonly used air separation method is cryogenic distillation. The cryogenic separation method converts air into liquid through a compression cycle and deep freezing method. Through cryogenic distillation, inert gases such as oxygen, nitrogen and argon are gradually separated from liquid air according to different boiling points. Before air separation, the air needs to be pretreated to remove impurities and moisture, generally including dust removal and dehumidification.

[0003] For example, in an air pretreatment device of a nitrogen generator with announcement number CN217746246U, the sealing protective cover can be taken out from the inspection port by rotating the bolts out from the machine body, and the two second limit bars can be driven to move upward. Since the two clamping plates clamp and fix the activated carbon filter, the activated carbon filter can be taken out from the inside of the machine body together, which is convenient for disassembling and removing the activated carbon filter. However, in actual use, there is some dust and impurities in the air. After the air is filtered through the activated carbon filter, the dust and impurities will stay on one side of the activated carbon filter. In order to ensure that the air can pass normally, the activated carbon filter needs to be frequently disassembled and cleaned. The cleaning of the filter can only be achieved by disassembly and assembly, which is inconvenient for cleaning the dust and has certain usage defects.

[0021] Compared with the prior art, the present invention has the following beneficial effects: the pretreatment device for air separation and the treatment method thereof are provided with treatment components on the top and inside of the treatment box, so that the air can be filtered and treated, and dust and impurities in the air can be prevented from adhering to the filter screen during the treatment, and the dust and impurities can be cleaned without disassembly, and the cleaning of the filter screen is more convenient, and the activated carbon filter screen can be cleaned or replaced conveniently, thereby improving convenience and practicality; 1. When the air is pre-treated before separation, start the drive motor to drive the rotating shaft to rotate, so that the rotating blades rotate, so that the inside of the treatment box is in a negative pressure state, and the outside air can be drawn into the treatment box. The impurities in the air can be filtered through the filter, and the moisture in the air can be absorbed through the activated carbon filter. While the rotating shaft is rotating, the output shaft and the connecting shaft can be driven to rotate through the meshing of the active bevel gear and the two driven bevel gears. After the output shaft rotates, the reciprocating screw rod can be driven to rotate through the cooperation of the first pulley and the second pulley, so that the movable sleeve moves up and down reciprocatingly, thereby driving the movable plate to move. During the movement, the movable plate drives the positioning sleeve to slide on the positioning rod for limiting. The reciprocating movement of the movable plate can clean one side of the filter through the bristles to prevent the filter from being dirty and blocked. , to avoid affecting the passage of air, the activated carbon filter is installed inside the treatment box through the installation groove. After long-term use, the activated carbon filter will reduce its adsorption performance. The rotating block can be moved so that the rotating block moves on the rotating rod and compresses the compression spring, so that the anti-slip pad on the rotating block leaves the mounting plate, so that the mounting plate loses its limit, and then the mounting plate can be removed, so that the activated carbon filter can be taken out, and the activated carbon filter can be cleaned or replaced. The air can be filtered through the treatment component, and dust and impurities in the air can be prevented from adhering to the filter while being treated. Dust and impurities can be cleaned to avoid disassembly, which makes it more convenient to clean the filter and facilitates the cleaning or replacement of the activated carbon filter, thereby improving convenience and practicality. 2. The movable plate can drive the movable rod to move when it moves back and forth to clean the filter. After the movable rod moves, the ball can rotate on the convex block to push the movable rod to move. The movement of the movable rod can drive the cleaning plate to move, and the telescopic spring can be stretched or compressed, so that the movable rod can move back and forth during the up and down movement, which can reduce the adhesion of dust on the cleaning plate. In the cleaning process, the filter is wiped, which will generate a certain amount of dust. The connection between the movable sleeve and the reciprocating screw rod and the connection between the positioning sleeve and the positioning rod need to be lubricated with lubricating oil. If dust is generated, the lubricating oil has a certain viscosity and is easily stained with dust. When lubrication is needed in the subsequent use process, add lubricating oil to the oil storage tank, open the valve on the mounting pipe, and allow a certain amount of lubricating oil to enter the telescopic hose and the box body. The cam is then closed and the valve is moved back and forth, and the control rod is driven away from the limit rod by the sliding connection with the sliding groove on the moving block, so that the oil outlet pipe is no longer intercepted, and the lubricating oil can leak out through the oil outlet pipe, thereby lubricating the movable sleeve and the positioning sleeve, and the movable rod is reset when the operation is stopped, so that the oil outlet pipe is intercepted to avoid the leakage of the lubricating oil and the waste, and when lubrication is not needed, the valve on the installation pipe is kept in a closed state, so that the lubricating oil does not enter the oil outlet pipe, and then the movable sleeve and the positioning sleeve can be lubricated when the air is processed, so that the friction of the movable sleeve and the positioning sleeve is large due to the failure to lubricate in time during the processing process, and unnecessary wear is avoided, which can improve the overall service life and improve practicality; 3. During the rotation process, the connecting shaft can drive the rotating rod to rotate and connect through the meshing of the first bevel gear and the second bevel gear. After the rotating rod rotates, the meshing of the fourth bevel gear and the third bevel gear drives the rotating shaft to rotate, so that the blades can rotate while processing the air, so that a negative pressure state is formed inside the exhaust pipe. When cleaning the filter, a breathable dust collecting belt is provided on the outside of the connecting pipe, so that the cleaned dust can be introduced into the breathable dust collecting bag through the exhaust pipe and the connecting pipe for easy collection, so as to facilitate the subsequent centralized treatment of the dust.

[0031] Working principle: When using the pretreatment device for air separation, first, according to Figure 1-Figure 9As shown, when the air is pre-treated before separation, the driving motor 201 is started to drive the rotating shaft 202 to rotate, so that the rotating blades 204 rotate, so that the inside of the processing box 1 is in a negative pressure state, and the outside air can be drawn into the processing box 1. The impurities in the air can be filtered through the filter 103, and the moisture in the air can be absorbed through the activated carbon filter 105. While the rotating shaft 202 is rotating, the output shaft 207 and the connecting shaft 208 can be driven to rotate through the engagement of the active bevel gear 205 and the two driven bevel gears 209. After the output shaft 207 rotates, the reciprocating screw rod 210 can be driven to rotate through the cooperation of the first pulley 211 and the second pulley 212, so that the movable sleeve 213 moves up and down, thereby driving the movable plate 216 to move. The movable plate 216 During the movement, the positioning sleeve 215 is driven to slide on the positioning rod 214 to limit the position. The reciprocating movement of the movable plate 216 can clean one side of the filter screen 103 through the bristles to prevent the filter screen 103 from being dirty and blocked, and to avoid affecting the passage of air. The activated carbon filter screen 105 is installed inside the treatment box 1 through the mounting groove 104. After long-term use, the activated carbon filter screen 105 will reduce the adsorption performance. The rotating block 303 can be moved so that the rotating block 303 moves on the rotating rod and compresses the compression spring 304, so that the anti-skid pad on the rotating block 303 leaves the mounting plate 301, so that the mounting plate 301 loses its limit, and then the mounting plate 301 can be removed, so that the activated carbon filter screen 105 can be taken out, and the activated carbon filter screen 105 can be cleaned or replaced; The movable plate 216 can drive the movable rod 220 to move when it moves back and forth to clean the filter 103. After the movable rod 220 moves, the ball 225 can rotate on the protrusion 224, so that the movable rod 220 is pushed to move. The movement of the movable rod 220 can drive the cleaning plate 219 to move, and the telescopic spring 222 can be stretched or compressed, so that the movable rod 220 can move back and forth during the up and down movement, which can reduce the adhesion of dust on the cleaning plate 219. In addition, the filter 103 is wiped during the cleaning process, which will generate a certain amount of dust. The connection and positioning sleeve between the movable sleeve 213 and the reciprocating screw rod 210 The connection between 215 and the positioning rod 214 needs to be lubricated by lubricating oil. If dust is generated, the lubricating oil has a certain viscosity and is easily stained with dust. When lubrication is needed in the subsequent use process, lubricating oil is added to the inside of the oil storage tank 226, and the valve on the installation pipe 227 is opened to allow a certain amount of lubricating oil to enter the telescopic hose 228 and the box body 229. The valve can then be closed, and the movable rod 220 drives the column rod 237 to reciprocate during the reciprocating movement. After the column rod 237 moves, it can drive the control rod 234 away from the limit rod 232 through the sliding connection with the sliding groove 236 on the moving block 235, so that the oil outlet pipe 230 is no longer moved. The flow is intercepted so that the lubricating oil can leak out through the oil outlet pipe 230, and then the movable sleeve 213 and the positioning sleeve 215 can be lubricated. When the operation is stopped, the movable rod 220 is reset to intercept the flow of the oil outlet pipe 230 to avoid the leakage of the lubricating oil and avoid waste. When lubrication is not needed, the valve on the mounting pipe 227 remains closed so that the lubricating oil does not enter the oil outlet pipe 230. When the air is processed, the movable sleeve 213 and the positioning sleeve 215 can be lubricated to avoid the friction of the movable sleeve 213 and the positioning sleeve 215 that is not lubricated in time during the processing process, thereby avoiding unnecessary wear. 08 During the rotation process, the first bevel gear 240 and the second bevel gear 241 are engaged to drive the rotating rod 239 to rotate. After the rotating rod 239 rotates, the fourth bevel gear 245 and the third bevel gear 244 are engaged to drive the rotating shaft 243 to rotate, so that the blades 246 can rotate while processing the air, so that a negative pressure state is formed inside the exhaust pipe 101. When cleaning the filter 103, a breathable dust collecting belt is provided on the outside of the connecting pipe 102, so that the cleaned dust can be introduced into the breathable dust collecting bag through the exhaust pipe 101 and the connecting pipe 102 for easy collection, so as to facilitate the subsequent centralized treatment of the dust.

9. A processing method of a pretreatment device for air separation, using a pretreatment device for air separation as claimed in any one of claims 1 to 8, wherein the specific steps are as follows: Step 1: When the air is pre-treated before separation, the driving motor (201) is started to drive the rotating shaft (202) to rotate, so that the rotating blades (204) rotate, so that the inside of the processing box (1) is in a negative pressure state, and the outside air can be drawn into the processing box (1). Impurities in the air can be filtered through the filter screen (103), and moisture in the air can be absorbed through the activated carbon filter screen (105). While the rotating shaft (202) rotates, the active bevel gear (205) and the two driven bevel gears (209) are meshed to drive the rotating shaft (202) to rotate. The output shaft (207) rotates with the connecting shaft (208). After the output shaft (207) rotates, the first pulley (211) and the second pulley (212) cooperate to drive the reciprocating screw (210) to rotate, so that the movable sleeve (213) moves up and down, thereby driving the movable plate (216) to move. During the movement, the movable plate (216) drives the positioning sleeve (215) to slide on the positioning rod (214) to limit the position. The reciprocating movement of the movable plate (216) can brush the bristles on one side of the filter screen (103). Clean the filter (103) to prevent it from being clogged by dirt and affecting the passage of air. The activated carbon filter (105) is installed inside the treatment box (1) through the installation slot (104). After long-term use, the activated carbon filter (105) will reduce its adsorption performance. The rotating block (303) can be moved so that the rotating block (303) moves on the rotating rod (302) and compresses the compression spring (304), so that the anti-skid pad on the rotating block (303) leaves the mounting plate (301), so that the mounting plate (301) loses its limit position, and the mounting plate (301) can be moved. The plate (301) is removed so that the activated carbon filter (105) can be taken out, and the activated carbon filter (105) can be cleaned or replaced. The processing component (2) allows the air to be filtered and treated, and dust and impurities in the air can be prevented from adhering to the filter (103) during the treatment. The dust and impurities can be cleaned and disassembly can be avoided, making it more convenient to clean the filter (103) and convenient to clean or replace the activated carbon filter (105), thereby improving convenience and practicality. Step 2: The movable plate (216) can drive the movable rod (220) to move when it reciprocates to clean the filter (103). After the movable rod (220) moves, the ball (225) can rotate on the protrusion (224), so as to push the movable rod (220) to move. The movement of the movable rod (220) can drive the cleaning plate (219) to move, and the telescopic spring (222) can be stretched or compressed, so that the movable rod (220) can reciprocate back and forth during the process of moving up and down, thereby reducing dust on the cleaning plate (219). The filter (103) is wiped during the cleaning process, which will generate a certain amount of dust. The connection between the movable sleeve (213) and the reciprocating screw (210) and the connection between the positioning sleeve (215) and the positioning rod (214) need to be lubricated by lubricating oil. If dust is generated, the lubricating oil has a certain viscosity and is easily stained with dust. When lubrication is required during subsequent use, lubricating oil is added to the oil storage tank (226), and the valve on the installation pipe (227) is opened to allow a certain amount of lubricating oil to enter the telescopic hose (228) and the box body (22 9), the valve can be closed afterwards, and the movable rod (220) drives the column rod (237) to move back and forth during the reciprocating movement. After the column rod (237) moves, it can drive the control rod (234) away from the limit rod (232) through the sliding connection with the sliding groove (236) on the movable block (235), so that the oil outlet pipe (230) is no longer intercepted, so that the lubricating oil can leak out through the oil outlet pipe (230), and then the movable sleeve (213) and the positioning sleeve (215) can be lubricated, and when the operation stops, the movable rod (220) The oil outlet pipe (230) is reset so as to cut off the flow of lubricating oil and avoid leakage of lubricating oil, thereby avoiding waste. When lubrication is not required, the valve on the mounting pipe (227) remains closed so that lubricating oil does not enter the oil outlet pipe (230). When air is processed, the movable sleeve (213) and the positioning sleeve (215) can be lubricated, thereby avoiding the large friction force caused by failure to lubricate the movable sleeve (213) and the positioning sleeve (215) in time during the processing process, thereby avoiding unnecessary wear and tear, thereby increasing the overall service life and improving practicality. Step 3: During the rotation process, the connecting shaft (208) can drive the rotating rod (239) to rotate and connect through the meshing of the first bevel gear (240) and the second bevel gear (241). After the rotating rod (239) rotates, the meshing of the fourth bevel gear (245) and the third bevel gear (244) drives the rotating shaft (243) to rotate, thereby causing the blades (246) to rotate while processing the air, so that a negative pressure state is formed inside the discharge pipe (101). When the filter (103) is cleaned, a breathable dust collection belt is sleeved on the outside of the connecting pipe (102), thereby facilitating the introduction of the cleaned dust into the breathable dust collection bag through the discharge pipe (101) and the connecting pipe (102), so as to facilitate collection and subsequent centralized treatment of the dust.
