Description

Technical Field

[0001] The utility model relates to the technical field of hydroxypropyl methylcellulose production and processing equipment, in particular to a material dividing device for a filter press in the production of hydroxypropyl methylcellulose. Background Art

[0002] Hydroxypropyl methylcellulose, also known as hypromellose, is a semi-synthetic, inactive and viscous polymer. It usually appears as a white or slightly yellow fine powder and can be used as a thickener, emulsifier and dispersant. During the production process, a filter press is required to complete solid-liquid separation. The filtrate enters the filter press through the feed port, and the filter medium intercepts the particles in the filtrate through the filter mesh, forming a filter cake in the filter chamber. The filtrate is discharged from the liquid outlet of the filter plate.

[0003] After hydroxypropyl methylcellulose completes solid-liquid separation through a filter press, it is necessary to adjust the pressure plate so that the filter cake falls into the material receiving box of the filter press. However, wet hydroxypropyl methylcellulose is sticky and easily adheres to the pressure plate and filter frame of the filter press. The unloading and material distribution structure of some existing hydroxypropyl methylcellulose production filter presses is relatively simple. Part of the hydroxypropyl methylcellulose will adhere to the pressure plate and filter frame and is difficult to fall off, resulting in the loss of some hydroxypropyl methylcellulose during the production process. Therefore, in response to the above problems, a material distribution device for a hydroxypropyl methylcellulose production filter press is proposed. Utility Model Content

[0029] The mounting frame 1 is a "U"-shaped frame, the sliding sleeves 2 are all "U"-shaped structures, the adjusting rods 3 are all vertically distributed, and the adjusting rods 3 can be limited by the mounting frame 1; the outer sides of the adjusting rods 3 are provided with threaded protrusions, and the inner sides of the adjusting blocks 5 are provided with threaded grooves. The splash-proof shell 7 is a rectangular frame structure, which can prevent the hydroxypropyl methylcellulose swept away from splashing everywhere; the mounting shells 9 are all rectangular shells, and the first cleaning plates 10 are all "L"-shaped structures. The first rotating rods 11 are horizontally distributed in the front and rear directions, and the second rotating rods 12 are horizontally distributed in the left and right directions. The second cleaning plates 13 and the soft brush 14 can be driven to rotate by the first rotating rod 11 and the second rotating rod 12; each group of the second cleaning plates 13 and the soft brush 14 has four, and the second cleaning plates 13 and the soft brush 14 are cross-distributed.

[0030] Working process: This device is an auxiliary device of the filter press. Taking the filter press that moves the pressure plate back and forth as an example, before use, the sliding sleeve 2 is installed on the frame of the filter press and the power is turned on. The device can slide back and forth on the filter press. When the device is not in use, the adjustment block 5 is located at the highest point in the movable range. At this time, the splash shield 7 is located above the pressure plate and filter frame of the filter press. The device does not affect the normal operation of the filter press. When the device is in use, the filter press can adjust the pressure plate to move backward so that the pressure plate and the filter frame are pressed together, and the hydroxypropyl methylcellulose liquid can be filtered. When the filter press completes a filtration, the pressure plate moves forward, the pressure plate and the filter frame are separated, and the distance between the pressure plate and the filter frame is greater than the splash shield. 7 in the front-to-back direction, the filter cake of hydroxypropyl methylcellulose falls into the material receiving box of the filter press. At this time, the first motor 4 is turned on by the controller 18, and the adjusting rod 3 is driven to rotate by the first motor 4 on the upper side of the mounting frame 1, and then the fixed sleeve 6 and the splash-proof shell 7 are driven downward by the adjusting block 5, so that the upper side of the splash-proof shell 7 is aligned with the uppermost side of the inner wall of the filter frame, and then the pressure plate of the filter press is moved backward, and the pressure plate pushes the splash-proof shell 7 and makes the splash-proof shell 7 probe into the interior of the filter frame, so that the front and rear sides of the splash-proof shell 7 are in contact with the pressure plate and the filter frame respectively, and then the second motor 17 is turned on to make the first motor 4 and the second motor 17 rotate together, and the splash-proof shell 7 can be driven downward by the first motor 4, and then the fixed sleeve 6 and the splash-proof shell 7 can be driven downward by the fixed sleeve 6 and the splash-proof shell 7 can be driven downward by the fixed sleeve 6. The block 8 and the mounting shell 9 drive the first rotating rod 11 and the second rotating rod 12 to move downward. At the same time, the second rotating rod 12 located at the front side is driven to rotate by the second motor 17, and then the two first rotating rods 11 and the second rotating rod 12 located at the rear side are driven to rotate synchronously through the meshing action of the first bevel gear 15 and the second bevel gear 16. The pressing plate and the filter frame can be cleaned by the rotating second cleaning plate 13 and the soft brush 14. At the same time, the internal corners of the filter frame are cleaned by the first cleaning plate 10 on the outside of the mounting shell 9. The cleaned hydroxypropyl methylcellulose can fall into the material receiving box of the filter press. After cleaning, the second motor 17 is turned off and the filter press is adjusted again. The pressure plate moves forward, and the sliding sleeve 2 is manually pulled to move the mounting frame 1 forward, so that the splash shield 7 can be removed from the filter frame, and the first motor 4 is reversed to reset the splash shield 7, and the filter press can be used normally; the device can clean the pressure plate and the filter frame through the first cleaning plate 10, the second cleaning plate 13 and the soft brush 14, and the second cleaning plate 13 and the soft brush 14 can be driven to rotate by the first rotating rod 11 and the second rotating rod 12 to improve the cleaning effect, and the splash shield 7 can be driven up and down by the adjusting rod 3 and the adjusting block 5 to quickly clean the pressure plate and the filter frame.
