[0002] The equipment for separating DMMn (polyoxymethylene dimethyl ether) refers to a device or system used to efficiently separate DMMn from its mixed materials. Such equipment or system usually contains multiple units to ensure the effective separation and purification of DMMn. The equipment is mainly composed of a pretreatment unit and a distillation unit. The pretreatment unit: This unit is usually used to remove solid impurities, acids, water, formaldehyde and other impurities in the material to provide clean raw materials for subsequent separation operations, which helps prevent impurities from interfering with the separation effect of DMMn and protect subsequent equipment from damage; the distillation unit is the core part of DMMn separation. It A distillation tower in an alkaline environment is used to separate the light and heavy components in the material by pressure swing. By controlling the pressure in the distillation tower, 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 the DMMn. The filter cloth plays a vital role in the solid-liquid separation process. Its core function is to achieve effective separation of solid particles and liquid in the liquid. Through the filtering effect of the filter cloth, solid impurities such as suspended matter and particulate matter in the liquid can be retained 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.

When impurities on the filter cloth need to be cleaned, the first L-shaped plate is driven upward by the lifting module, and at the same time, the filter box is driven upward by the telescopic mechanism. When the second inclined surface and the third inclined surface are against each other, the first rotating plate can be pushed to move under the limiting action of the U-shaped block, and at the same time, the first rack and the second slider are driven to move, and the reset 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. At the same time, when the first rack moves, the sixth connecting member is connected to the first rack. The plate and the third guide rod drive the fifth connecting plate and the third sliding block to move. At the same time, the second rack is driven 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 the same time, the sixth spring is compressed, which facilitates the collection of impurities on the filter cloth. At the same time, the first rotating plate can reciprocate across the triangular block, thereby pushing the rotating frame to swing back and forth, forming a shaking effect, so that the impurity collection effect is better, and the collection box can be moved back and forth, which can also form a shaking effect, which is convenient for the impurities falling into the collection box to be spread out, so that the collection effect is better.

[0016] (2) This DMMn separation device is provided with 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 to move upward. At the same time, the first spring is compressed. When the disc moves upward, it can drive the moving plate to move 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 no longer moves. At this time, it can ensure that the ball applies a constant squeezing force to the filter cloth. When the first L-shaped plate continues to move upward, the seventh spring is compressed. At the same time, the first pushing rod is driven to move upward along the inclined slot through the first L-shaped frame, so that the pushing block can be pushed to move in the direction away from the support plate. The fourth spring is compressed, and when the pushing When the block moves, it can drive the telescopic sleeve rod to move, thereby pushing the pull rope. At this time, the U-shaped plate can be pulled to move, and 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, and at the same time, drive the disc to slide downward along the first inclined surface, thereby pushing the moving plate to move in the direction close to the moving block. At the same time, the second spring is compressed, and the change in the distance of the moving plate is detected by the distance sensor to determine whether the filter cloth is damaged, thereby facilitating the detection of the filter cloth and ensuring the effect of filtering and separation. When damage is detected, the motor is started, and the rotation of the motor drives the rotation of the winding roller, thereby the damaged filter cloth can be wound up, and the new filter cloth on the material roller continues to be transported to the rotating frame for filtration, thereby facilitating the replacement of the filter cloth and ensuring the efficiency and effect of filtering and separation.

[0017] (3) This type of DMMn separation equipment is provided with a reset mechanism, etc., so that when it is necessary to process the impurities collected in the collection box, the U-shaped frame is pulled to move the scraper away from the notch, thereby squeezing the impurities in the collection box, making it easier for the gas and liquid to re-enter the distillation tank through the discharge pipe. Then, the cover plate is opened, and the squeezed impurities can be discharged through the collection port, thereby ensuring the effect of impurity collection. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The telescopic mechanism includes a third connecting block 701 fixedly connected to the side wall of the filter box 1101, and the top of the third connecting block 701 is fixedly connected to two symmetrically arranged sleeve rods 702, the side wall of the sleeve rod 702 is sleeved with a sleeve 703, and the upper end of the sleeve 703 is fixed to the bottom of the first L-shaped plate 1110, and the side wall of each sleeve 703 is sleeved with a seventh spring 704. When the filter box 1101 is in contact with the baffle 1108, the filter box 1101 no longer moves. At this time, it can ensure that the ball 1204 applies a constant extrusion pressure to the filter cloth 1106. When the first L-shaped plate 1110 continues to move upward, the seventh spring 704 is compressed.

[0031] Working principle: When in use, during distillation, DMMn solution is fed into the distillation tank 1 through the liquid inlet 101, and the solution falls on the filter cloth 1106 after passing through the feed port 1102 for filtration. When impurities on the filter cloth 1106 need to be cleaned, the first L-shaped plate 1110 is driven upward by the lifting module 1109, and at the same time, the filter box 1101 is driven upward by the telescopic mechanism. When the second inclined surface 404 and the third inclined surface 409 are against each other, under the limiting action of the U-shaped block 405, the first rotating plate 403 can be pushed to move, and at the same time, the first rack 306 and the second slider 304 are driven to move, and the reset spring 305 is compressed. When the first rack 306 moves, the first gear 301 and the rotating shaft 1103 can be driven 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, the sixth connecting plate 608 and The third guide rod 609 drives the fifth connecting plate 606 and the third slider 603 to move. At the same time, the second rack 607 is driven 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 slide groove 505, thereby pulling the collecting box 1302 to move to the bottom of the filter box 1101 through the third connecting plate 504. At the same time, the sixth spring 904 is compressed, which facilitates the collection of impurities on the filter cloth 1106. At the same time, the first rotating plate 403 can reciprocate over the triangular block 410, thereby pushing the rotating frame 1104 to swing back and forth, forming a shaking effect, so that the collection effect of impurities is better, and the collection box 1302 can be reciprocated, which can also form a shaking effect, which is convenient for the impurities falling into the collection box 1302 to be spread out, so that the collection effect is better.

[0032] After the cleaning of the filter cloth 1106 is completed, when the first rotating plate 403 passes over the pushing plate 408, the rotating frame 1104 can rotate and reset under the action of the reset 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 to move upward. At the same time, the first spring 1206 is compressed. When the disc 1207 moves upward, it can drive the moving plate 201 to move 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 110 1 no longer moves, at this time, it can be ensured that the ball 1204 applies a constant extrusion force to 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, the first push rod 811 is driven to move upward along the inclined groove 809 through the first L-shaped frame 810, so that the push block 807 can be pushed to move in the direction 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, thereby pushing the pull rope 814. At this time, the U-shaped plate 1202 can be pulled 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.

[0033] 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, and at the same time, drive the disc 1207 to slide downward along the first inclined surface 203, so as to push the moving plate 201 to move in the direction close to the moving block 205. At the same time, the second spring 206 is compressed, and the change in the distance of the moving plate 201 is detected by the distance sensor 207, so as to determine whether the filter cloth 1106 is damaged, thereby facilitating the detection of the filter cloth 1106 to ensure the filtering and separation effect. When damage is detected, the motor 1407 is started, and the rotation of the motor 1407 drives the rotation of the winding roller 1409, so as to be able to reel in the damaged filter cloth 1106, and the new filter cloth 1106 on the material roller 1405 continues to be transported to the rotating frame 1104 for filtration, so as to facilitate the replacement of the filter cloth 1106 to ensure the efficiency and effect of filtering and separation.

[0034] When the impurities collected in the collection box 1302 need to be processed, the U-shaped frame 1001 is pulled to move the scraper 1305 away from the notch 1307, thereby squeezing the impurities in the collection box 1302, making it easier for the gas and liquid to re-enter the distillation tank 1 through the discharge pipe 1306. Next, the cover plate 1304 is opened, and the squeezed impurities can be discharged through the collection port 1303, thereby ensuring the effect of impurity collection.
