Description

Technical Field

[0001] The invention relates to the technical field of desiccant processing, in particular to a dust removal and purification device used for desiccant production. Background Art

[0002] Moisture control is closely related to product yield. For food, under appropriate temperature and humidity conditions, bacteria and mold will multiply at an alarming rate, causing food to spoil. Electronic products can also suffer from metal oxidation, dampness, and discoloration due to excessive humidity. Desiccant is used to prevent excess moisture from causing defective products.

[0003] Desiccant is often produced in different forms depending on its type and demand. Some desiccants are eventually prepared into powder or an intermediate form with powder, which will cause dust. Due to its good water absorption effect, if desiccant is allowed to float in the air, it will not only pollute the environment and waste resources, but also threaten the health of production workers. In order to ensure the safety of employees, dust removal and purification equipment is used in desiccant processing workshops to purify the air and recover the desiccant dust in the air.

[0004] The air outlet channels of existing dust removal and purification equipment are limited, and the desiccant dust will be concentrated near the filter element of the air outlet channel in the equipment due to the influence of wind, thereby affecting the air circulation inside the dust removal and purification equipment. As a result, the amount of desiccant dust that can be collected by the dust removal and purification equipment is extremely limited, and staff are required to clean the dust removal and purification equipment frequently, which increases manpower consumption and is not conducive to improving production efficiency.

[0021] like Figure 2-4 As shown, a filter mechanism 200 is provided on the upper side of the interior of the housing 100. The filter mechanism 200 removes dust and purifies the air flowing through the housing 100. The filter mechanism 200 includes a turntable 210. The top surface of the turntable 210 is rotatably connected to the top surface of the inner side of the housing 100.

[0022] like Figure 4-5 As shown, the driving mechanism 300 includes a lifting seat 310, which is slidably connected to the inner wall of the cavity 130. A plurality of support springs 320 are evenly fixed between the bottom surface of the lifting seat 310 and the top surface of the first filter plate 150. The top surface of the lifting seat 310 is connected and fixed to the second filter plate 220 through two connecting plates 330. An impeller 340 coaxial with the second filter plate 220 is provided between the two connecting plates 330.

[0023] like Figure 4 、 Figure 7-Figure 9 As shown, the bottom surface of the impeller 340 is coaxially fixedly connected to a rotating shaft 350, and the rotating shaft 350 is rotatably connected to the inner wall of the cavity 130.

An electric motor 360 is coaxially arranged below the rotating shaft 350.

[0024] The motor 360 is fixedly connected to the inner walls of the two connecting plates 330, and the output end of the motor 360 is coaxially fixedly connected to the drive shaft 370. The upper end of the drive shaft 370 is an annular structure with equal spacing and is provided with a plurality of side grooves 371. The inner wall of the side groove 371 is elastically connected with an extrusion block 390 through a plurality of first return springs 380. The extrusion block 390 extends to the upper end of one side outside the side groove 371 and is an oblique quadrangular pyramid structure.

[0025] like Figure 4 、 Figure 8 、 Figure 10 As shown, a fixed shaft 311 is fixed to the top of the lifting seat 310 on the surface coaxial with the turntable 210, a central shaft 312 is coaxially provided above the fixed shaft 311, a circular cavity 212 is coaxially penetrated through the middle of the turntable 210, and an axis groove 230 is provided on the inner top surface of the outer shell 100 for rotating with the central shaft 312. A coil spring 313 is sleeved on the outer wall of the central shaft 312, and the outer end of the coil spring 313 is connected and fixed to the inner wall of the circular cavity 212.

[0026] The shaft groove 230 is a T-shaped structure with a larger top and a smaller bottom. The upper end of the central shaft 312 is coaxially fixedly connected to a ratchet 314. A plurality of pawls 315 that engage with the ratchet 314 are evenly provided on the upper part of the shaft groove 230. The pawls 315 are rotatably connected to the inner wall of the shaft groove 230. A compression spring 319 is fixed between the outer wall of the pawl 315 and the inner wall of the shaft groove 230. A second circular groove 316 is coaxially opened on the bottom surface of the central shaft 312. The inner wall of the second circular groove 316 is opened in a circular structure with equal spacing and a plurality of curved grooves 3161. Any two adjacent curved grooves 3161 are connected end to end through a vertical groove 3162.

[0027] A guide block 3111 is fixed to the upper end of the fixed shaft 311, and the guide block 3111 is slidably fitted with the curved groove 3161 and the vertical groove 3162. A block groove 3163 is provided at the connection between the curved groove 3161 and the vertical groove 3162. A stopper 318 is elastically connected to the inside of the block groove 3163 through a second return spring 317. The top surface of the stopper 318 is an inclined structure with the upper end offset toward the block groove 3163, and the bottom surface of the stopper 318 is an inclined structure offset upward near one end.

[0028] like Figure 1-2 As shown, a metal bellows 160 is threadedly connected to the upper part of the air inlet 110, and a dust collector head 170 is connected to the end of the metal bellows 160 away from the shell 100. A cleaning port 180 is opened in the middle of the side wall of the shell 100 away from the air outlet 110, and a sealing plate 181 is inserted into the cleaning port 180. The sealing plate 181 is symmetrically fixed with two clamping plates 182 on the side wall close to the shell 100. The clamping plate 182 is an L-shaped structure, and the protrusion on the outer wall of the clamping plate 182 is snap-fitted with the edge of the cleaning port 180 close to the inner side of the shell 100.

[0029] Working Principle: The operator can place the device next to the powdered desiccant production equipment and then align the dust collector head 170 with the opening of the powdered desiccant production equipment where dust is easily released. The opening of the dust collector head 170 is a circular structure, but one side of the outer wall is set to be flat and has screw holes at the four corners, which allows the operator to use an external fixing bracket to fix it near the use location. After the device is fixed, the staff can use the motor 360 to drive the impeller to rotate. The rotation of the impeller 340 will drive the outside air to be continuously sucked into the housing 100 from the air inlet 110, and then pass through the inside of the circular tube 211 corresponding to the air inlet 110 and the inside of the cavity 130, and finally pass through the first filter plate 150 and be discharged from the air outlet 140. During this period, the desiccant dust in the air will be intercepted by the second filter plate 220 and temporarily stored in the circular tube 211. The holes of the first filter plate 150 set at the air outlet 110 are all set to be relatively large. The setting of this filter plate is not to intercept dust but to provide a fulcrum for the multiple support springs 320 on the bottom surface of the lifting seat 310, so as to ensure the operation of the driving mechanism 300. As the amount of trapped dust increases, the height of the second filter plate 220 will also decrease due to the increase in the weight of the dust. The top surface of the second filter plate 220 is set to a raised conical structure. This design can ensure that the dust can be dispersed to the surroundings as much as possible to avoid prematurely covering the holes on the second filter plate 220. When the amount of dust is so great that the second filter plate 220 is pressed out of the plate groove 211, the connecting plates 330 on both sides of the second filter plate 220 will also press the lifting seat 310 to the lowest point. At this time, the multiple extrusion blocks 390 on the drive shaft 370 will move below the dial plate 352, and the drive of the drive shaft 370 by the motor 360 can no longer drive the rotating shaft 350 to rotate together, and the impeller 340 will stop inhaling external air. When the second filter plate 220 moves out of the plate groove 2111, the restriction of the second filter plate 220 on the rotation of the turntable 210 is also released. At first, when the second filter plate 220 is lifted up by the rebound force of the support spring 320 and inserted into the plate groove 2111, the guide block 3111 on the fixed shaft 311 will also move toward the upper part of the second circular groove 316. During the upward movement, the guide block 3111 will first contact the bottom surface of the stopper 318. Because the bottom surface of the stopper 318 is close to the end of the curved groove 3161, the inclined surface is perpendicular to the inner wall of the vertical groove 3162 and the inner wall of the lower end of the curved groove 3161. The squeezing force of 318 cannot press the stopper 318 into the block groove 3163. On the contrary, the guide block 3111 will move toward the curved groove 3161 under the guidance of the bottom surface of the stopper 318. However, the fixed shaft 311 is fixed to the top surface of the lifting seat 310 and cannot rotate. Then the central shaft 312 with the curved groove 3161 will rotate. During this process, the rotating ratchet 314 is not restricted by the pawl 315. At the same time, as the central shaft 312 rotates, the coil spring 313 sleeved on its outer wall will also tighten. However, at this time, the second filter plate 220 has already entered the plate groove 2111, so The turntable 210 is restricted and cannot rotate until the second filter plate 220 is moved out of the plate slot 2111 again under the pressure of a large amount of desiccant dust. During the downward movement, the guide block 3111 passes through the vertical slot 3162, so the central axis 312 does not rotate. When the guide block 3111 moves to the position of the stop block 318, it will squeeze the top surface of the stop block 318. The inclined surface of the top surface of the stop block 318 is set to be higher than the end away from the block slot 3163 at the end close to the block slot 3163. Therefore, the stop block 318 will be easily pressed into the block slot 3163 at this time without affecting the guide block 31 When the guide block 3111 moves downward, after it passes the block groove 3163, it will pop out again under the action of the second return spring 317, and when the guide block 3111 rises next time, it will play the role of guiding the guide block 3111 to correspond with the curved groove 3161. Without the restriction of the second filter plate 220, the rewinding force of the coil spring 313 can be released. The central axis 312 restricted by the ratchet 314 and the pawl 315 cannot reverse. Therefore, the coil spring 313 can only drive the turntable 210 to rotate through the outer end. The angle of each rotation is just enough to match the next round tube 211 to the bottom of the air inlet 110. The circular tube 211 with a large amount of dust accumulated will leave the position corresponding to the second filter plate 220 during rotation. For this purpose, the opening end of the cavity 130 of the device is set as two circles, one of which corresponds to the circular cavity 212 to facilitate the up and down movement of the fixed shaft 311, and the other corresponds to the position of the second filter plate 220. After the second filter plate 220 moves out of the circular tube 211, its top surface will be flush with the top surface of the fixing seat 120, and the top surface of the second filter plate 220 and the top surface of the fixing seat 120 are in sliding contact with the bottom surface of the turntable 210 at this time. The tube 211 is provided with a second filter plate 220 or the top surface of the fixing seat 120 as an obstruction in the path of the fixing seat 120. This prevents the desiccant powder collected in the tube 211 from falling into the cavity 130. The powder inside the tube 211 will not be completely dumped into the housing 100 until the position of the tube 211 is offset from the fixing seat 120. The staff only needs to remove the sealing plate 181 periodically to clear the desiccant powder from the cleaning port 180. The housing 100 of the device has a large space inside, which can accommodate a large amount of desiccant powder. On the other hand, when the second filter plate 220 corresponds to the next circular tube 211, because there is no weight pressure from the desiccant powder, it and the lifting seat 310 below it will rebound synchronously, and the second filter plate 220 will be inserted into the plate groove 2111. The fixed shaft 311 will also drive the central shaft 312 to move and store energy again. At the same time, as the driving shaft 370 rises, the multiple extrusion blocks 390 thereon will also move to the corresponding side of the dial plate 352, and the impeller 340 will again rotate with the output end of the motor 360 to suck the outside air into the interior of the housing 100. It should be noted that even if the position of the extrusion block 390 overlaps or partially overlaps with the dial plate 352 during the rise, the extrusion block 390 will first sink into the side groove 3163 under the pressure of the oblique quadrangular pyramid slope of the dial plate 352, and will not pop out again until the dial plate 352 no longer hinders the extrusion block 390, and return to its original position during rotation to push the dial plate 352.
