Description

TECHNICAL FIELD

[0001] The utility model belongs to starch slurry suction filter, concretely is a kind of high-efficiency energy-saving device for filtering starch slurry. BACKGROUND

[0002] Starch paste (commonly known as starch paste) is the most commonly used binder in tablets, commonly used at 8%-15% concentration, and 10% starch paste is most commonly used;If the material is poor in compressibility, the concentration of starch paste can be appropriately increased to 20%, conversely, the concentration of starch paste can be appropriately reduced, such as aluminum hydroxide tablets using 5% starch paste as binder.Starch paste preparation method mainly has two methods of boiling paste and flushing paste, which utilizes the pasteability of starch.

[0003] Among them, in order to increase the concentration of existing starch paste, water in starch paste needs to be extracted, and the existing method is to place starch paste in a tank, then place filter cloth, and use suction pump to suck outside the filter cloth, which although blocks starch and sucks water through filter cloth, but starch accumulates at filter cloth, which also affects the suction effect.

[0007] When using the present application, the suction pump sucks water out of the water suction port through the water suction pipe, wherein the starch paste enters the cylinder through the feed pipe, wherein under the action of the suction pump, water enters the water suction pipe through the filter cloth and water-permeable hole and is sucked out of the water suction pipe, and starch accumulates on the filter cloth of the arc-shaped plate, wherein the extracted starch paste is taken out from the circular through slot.When a certain amount of starch accumulates on the filter cloth, the arc-shaped plate is obtained by the obtaining device, and the arc-shaped plate slides along the arc-shaped groove, so that the filter cloth at the new position is located below the water suction port, and the starch on the filter cloth far away is scraped off, so that the filter cloth is used for a long time, and the suction efficiency is improved.

[0008] Preferably, the driving device includes an outward-facing arc-shaped rack, which is coaxial with the cylinder and slidably fitted onto the slider. The arc-shaped rack is fixedly connected to an arc-shaped plate. A mounting groove is provided on one side of the arc-shaped groove, and a drive motor is fixedly installed in the mounting groove. The shaft of the drive motor is coaxially and fixedly connected to a gear that meshes with the rack. The rotation of the drive motor shaft drives the rotation of the gear, which in turn drives the rack to rotate. The rotation of the gear causes the arc-shaped rack to rotate along the axis of the cylinder, thereby moving the arc-shaped plate.

[0009] Preferably, the cylinder has a cavity with several water outlets connected to an arc-shaped groove. The cavity is also connected to a valve-controlled water outlet pipe connected to a water source. A drainage groove, opposite to the inner cavity, is located on the arc-shaped groove. Cleaning water enters the cavity via the water source and outlet pipe, is dispersed to each water outlet, and is sprayed out from the outlets, achieving backwashing of the filter cloth. The water flowing out enters the cylinder through the drainage groove and can be drawn out.

[0010] Preferably, the inner side of the arc-shaped rack is fixedly provided with a slide rail along its arc surface, and a slider that cooperates with the slide rail is provided on the arc groove.

[0011] Preferably, a rotating rod is coaxially mounted inside the cylinder. The rear end of the rotating rod extends out of the cylinder and is rotatably connected via a sealed bearing. The protruding end of the rotating rod is coaxially and fixedly connected to the rotating shaft of a fixed motor. Several levers are evenly fixedly mounted circumferentially on the portion of the rotating rod located inside the cylinder. The rotation of the fixed motor shaft drives the rotation of the rotating rod, which in turn drives the rotation of the levers, thereby achieving stirring inside the cylinder and ensuring uniform starch slurry concentration within the cylinder.

[0012] Preferably, the circular through groove of the cylinder has an internal thread, and the front baffle is threadedly connected to the circular through groove. Rotating the front baffle allows the front baffle to seal and disengage from the circular through groove.

[0013] The beneficial effects of this utility model are as follows: When starch slurry accumulates on the filter cloth, the filter cloth can be moved to one side, so that the new position of the filter cloth is at the water inlet, and the suction can continue. This prevents the low suction efficiency caused by starch blockage, and at the same time, it can achieve backwashing of the filter cloth and increase the service life. Attached Figure Description
