Description

Technical Field

[0001] The present invention relates to the technical field of filtration and separation, and specifically to a device for separating DMMn. Background Art

[0002] The device for separating DMMn (dimethoxymethane) refers to a device or system used to efficiently separate DMMn from its mixed materials. Such devices or systems usually include multiple units to ensure the effective separation and purification of DMMn. The device mainly consists of a pretreatment unit and a rectification unit. Pretreatment unit: This unit is usually used to remove solid impurities, acids, water, formaldehyde and other impurities in the materials, providing clean raw materials for subsequent separation operations. This helps prevent impurities from interfering with the separation effect of DMMn and protects subsequent equipment from damage. The rectification unit is the core part of DMMn separation. It uses a rectification column in an alkaline environment to separate the light and heavy components in the materials under variable pressure. By controlling the pressure in the rectification column, the separation of different components can be achieved under different pressure conditions. In the pretreatment unit, filter cloth is usually used to filter the solid impurities in DMMn. The filter cloth plays a crucial role in the solid-liquid separation process. Its core function is to effectively separate the solid particles in the liquid from the liquid state. Through the filtering action of the filter cloth, suspended solids, particulate matters and other solid impurities in the liquid can be intercepted on the surface of the filter cloth, allowing the clean liquid to flow out through the filter cloth, thereby achieving the purpose of purifying the liquid.

[0003] However, when the existing DMMn separation devices are in use, it is not convenient to filter and collect the impurities on the surface of the filter cloth, which affects the efficiency and effect of filtration and separation. Moreover, after long-term use, the filter cloth is prone to damage due to the impact of liquid and other factors, and it is not easy to be detected in time, which also affects the efficiency and effect of filtration and separation.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1)The device for separating DMMn, by setting a driving mechanism, etc., during distillation, supplies a DMMn solution into the distillation tank through the liquid inlet. The solution falls on the filter cloth for filtration after passing through the feed inlet. When it is necessary to clean the impurities on the filter cloth, the lifting module drives the first L-shaped plate to move upward. At the same time, the telescopic mechanism drives the filter box to move upward. When the second inclined surface abuts against the third inclined surface, under the limiting action of the U-shaped block, it can push the first rotating plate to move, and at the same time, drive the first rack and the second slider to move, and the return spring is compressed. When the first rack moves, it can drive the first gear and the rotating shaft to rotate, thereby driving the rotating frame and the filter cloth to flip by a certain degree. At the same time, when the first rack moves, it drives the fifth connecting plate and the third slider to move through the sixth connecting plate and the third guide rod. At the same time, it drives the second rack to move through the second L-shaped frame, thereby driving the second gear and the rotating rod to rotate, and then driving the second rotating plate to rotate. At this time, the second push rod can slide in the second chute, thereby pulling the collection box to move below the filter box through the third connecting plate. At the same time, the sixth spring is compressed, so as to facilitate the collection of impurities on the filter cloth. At the same time, the first rotating plate can reciprocally cross the triangular block, so as to be able to push the rotating frame to swing reciprocally, forming a shaking effect, making the collection effect of impurities better. And, it can reciprocally move the collection box, which can also form a shaking effect, facilitating the spreading of the impurities falling into the collection box, making the collection effect better.

[0020] (2) For the device for separating DMMn, by setting up a detection mechanism, etc., after the filter cloth is cleaned, when the first rotating plate passes over the pushing plate, the rotating frame can rotate and reset under the action of the reset spring. When the filter box continues to move upward, when the filter cloth abuts against the ball, it can push the moving rod and the disc upward. At the same time, the first spring is compressed. When the disc moves upward, it can drive the moving plate upward. When the moving plate moves upward, it can drive the first slider to move upward along the fixed rod through the first T-shaped guide rod and the moving block. When the filter box abuts against the baffle, the filter box stops moving. At this time, it can ensure that the ball exerts a constant squeezing force on the filter cloth. When the first L-shaped plate continues to move upward, the seventh spring is compressed. At the same time, it drives the first pushing rod to move upward along the inclined groove through the first L-shaped frame, so as to be able to push the pushing block to move away from the support plate. The fourth spring is compressed. And when the pushing block moves, it can drive the telescopic sleeve rod to move, so as to push the pull rope. At this time, it can pull the U-shaped plate to move. At the same time, the third spring is compressed, so that the ball can roll on the surface of the filter cloth. When the filter cloth is damaged, the moving rod and the ball can move downward under the action of the first spring. At the same time, it drives the disc to slide downward along the first inclined plane, so as to be able to push the moving plate to move closer to the moving block. At the same time, the second spring is compressed. And by detecting the change in the distance of the moving plate through the distance sensor, it can be determined whether the filter cloth is damaged, so as to facilitate the detection of the filter cloth and ensure the filtering and separation effect. When it is detected that there is damage, start the motor. The rotation of the motor drives the rotation of the winding roller, so as to be able to wind up the damaged filter cloth, and the new filter cloth on the material roller continues to be conveyed into the rotating frame for filtration, so as to facilitate the replacement of the filter cloth and ensure the efficiency and effect of filtration and separation.

[0021] (3) For the device for separating DMMn, by setting up a reset mechanism, etc., when it is necessary to process the impurities collected in the collection box, pull the U-shaped frame, so that the scraping plate moves away from the notch, so as to be able to squeeze the impurities in the collection box, facilitating the gas and liquid to enter the distillation tank again through the discharge pipe. Then, open the cover plate, and the squeezed impurities can be discharged through the collection port, so as to ensure the effect of impurity collection. BRIEF DESCRIPTION OF THE DRAWINGS

When the filter box 1101 moves upward, when the second inclined surface 404 abuts against the third inclined surface 409, under the limiting action of the U-shaped block 405, the first rotating plate 403 can be pushed to move. At the same time, the first rack 306 and the second slider 304 are driven to move. When the filter box 1101 moves downward, the first rotating plate 403 can rotate upward along the third rotating pin 402. At this time, the first rack 306 is not pushed to move.

By driving the rotating rod 502 to rotate through the driving assembly, the second rotating plate 503 is driven to rotate. At this time, the second push rod 506 can slide in the second sliding groove 505, so as to pull the collection box 1302 to move below the filter box 1101 through the third connecting plate 504.

[0052] The driving assembly includes a second gear 601 fixedly sleeved on the side wall of the rotating rod 502.

At the same time, the second rack 607 is driven to move through the second L-shaped frame 605, so as to drive the second gear 601 and the rotating rod 502 to rotate.

[0053] The reset mechanism includes a U-shaped frame 1001 inserted into the side wall of the fixed cover 1301. The U-shaped frame 1001 is fixedly connected to the side wall of the scraper 1305. Two symmetrically arranged fourth T-shaped guide rods 1002 are inserted into the side wall of the U-shaped frame 1001. A fifth spring 1003 is sleeved on the side wall of each fourth T-shaped guide rod 1002, which plays a role in guiding and resetting the movement of the scraper 1305.

[0054] The reset assembly includes a second L-shaped plate 901 fixedly connected to the side wall of the collection box 1302. Two symmetrically arranged fourth guide rods 902 are fixedly connected to the side wall of the second L-shaped plate 901. A second connecting block 903 is sleeved on the side wall of the fourth guide rod 902. The second connecting block 903 is fixedly connected to the side wall of the fixed cover 1301. A sixth spring 904 is sleeved on the side wall of each fourth guide rod 902, which plays a role in guiding and resetting the movement of the collection box 1302.

[0055] The telescopic mechanism includes a third connecting block 701 fixedly connected to the side wall of the filter box 1101. Two symmetrically arranged sleeve rods 702 are fixedly connected to the top of the third connecting block 701. A sleeve 703 is sleeved on the side wall of the sleeve rod 702, and the upper end of the sleeve 703 is fixedly connected to the bottom of the first L-shaped plate 1110. A seventh spring 704 is sleeved on the side wall of each sleeve 703. When the filter box 1101 abuts against the baffle 1108, the filter box 1101 stops moving. At this time, it can ensure that the ball 1204 applies a constant squeezing force to the filter cloth 1106. When the first L-shaped plate 1110 continues to move upward, the seventh spring 704 is compressed.

[0056] Working principle: When in use, during distillation, the DMMn solution is supplied into the distillation tank 1 through the liquid inlet 101. The solution falls on the filter cloth 1106 for filtration after passing through the feed inlet 1102. When it is necessary to clean the impurities on the filter cloth 1106, the lifting module 1109 drives the first L-shaped plate 1110 to move upward. At the same time, the telescopic mechanism drives the filter box 1101 to move upward. When the second inclined surface 404 abuts against the third inclined surface 409, under the limiting action of the U-shaped block 405, it can push the first rotating plate 403 to move. At the same time, it drives the first rack 306 and the second slider 304 to move, and the return spring 305 is compressed. When the first rack 306 moves, it can drive the first gear 301 and the rotating shaft 1103 to rotate, thereby driving the rotating frame 1104 and the filter cloth 1106 to flip 180 degrees. At the same time, when the first rack 306 moves, it drives the fifth connecting plate 606 and the third slider 603 to move through the sixth connecting plate 608 and the third guide rod 609. At the same time, it drives the second rack 607 to move through the second L-shaped frame 605, thereby driving the second gear 601 and the rotating rod 502 to rotate, and then driving the second rotating plate 503 to rotate. At this time, the second push rod 506 can slide in the second chute 505, thereby pulling the collection box 1302 to move below the filter box 1101 through the third connecting plate 504. At the same time, the sixth spring 904 is compressed, so as to facilitate the collection of the impurities on the filter cloth 1106. At the same time, the first rotating plate 403 can reciprocate over the triangular block 410, so as to push the rotating frame 1104 to swing reciprocally, forming a shaking effect, making the collection effect of the impurities better. And, it can reciprocate the collection box 1302, which can also form a shaking effect, facilitating the impurities falling into the collection box 1302 to be laid flat, making the collection effect better.

[0057] After the filter cloth 1106 is cleaned, when the first rotating plate 403 passes over the push plate 408, the rotating frame 1104 can rotate and reset under the action of the return spring 305. When the filter box 1101 continues to move upward, when the filter cloth 1106 abuts against the ball 1204, it can push the moving rod 1203 and the disc 1207 upward. At the same time, the first spring 1206 is compressed. When the disc 1207 moves upward, it can drive the moving plate 201 upward. When the moving plate 201 moves upward, it can drive the first slider 209 to move upward along the fixed rod 208 through the first T-shaped guide rod 204 and the moving block 205. When the filter box 1101 abuts against the baffle 1108, the filter box 1101 stops moving. At this time, it can ensure that the ball 1204 exerts a constant extrusion force on the filter cloth 1106. When the first L-shaped plate 1110 continues to move upward, the seventh spring 704 is compressed. At the same time, it drives the first push rod 811 to move upward along the inclined groove 809 through the first L-shaped frame 810, so as to be able to push the push block 807 to move away from the support plate 805. The fourth spring 808 is compressed. And when the push block 807 moves, it can drive the telescopic sleeve rod 812 to move, so as to push the pull rope 814. At this time, it can pull the U-shaped plate 1202 to move. At the same time, the third spring 804 is compressed, so that the ball 1204 can roll on the surface of the filter cloth 1106.

[0058] When the filter cloth 1106 is damaged, the moving rod 1203 and the ball 1204 can move downward under the action of the first spring 1206. At the same time, it drives the disc 1207 to slide downward along the first inclined surface 203, so as to be able to push the moving plate 201 to move toward the moving block 205. At the same time, the second spring 206 is compressed. And by detecting the change in the distance of the moving plate 201 through the distance sensor 207, it can be determined whether the filter cloth 1106 is damaged, so as to facilitate the detection of the filter cloth 1106 and ensure the filtering and separation effect. When it is detected that there is damage, the motor 1407 is started. The rotation of the motor 1407 drives the rotation of the winding roller 1409, so as to be able to wind up the damaged filter cloth 1106. And the new filter cloth 1106 on the material roller 1405 continues to be conveyed into the rotating frame 1104 for filtration, so as to facilitate the replacement of the filter cloth 1106 and ensure the efficiency and effect of filtration and separation.

[0059] When it is necessary to process the impurities collected in the collection box 1302, pull the U-shaped frame 1001, so that the scraper 1305 moves away from the notch 1307, so as to be able to squeeze the impurities in the collection box 1302, facilitating the gas and liquid to enter the distillation tank 1 again through the discharge pipe 1306. Then, open the cover plate 1304, and the squeezed impurities can be discharged through the collection port 1303, so as to ensure the effect of impurity collection.
