Description

Crushing and filtering device

Technical Field

The utility model belongs to the technical field of the mechanical chemical industry, concretely relates to broken filter equipment.

Background

In the chemical production process, a plurality of production raw materials, purifying agents and catalysts are crushed, filtered and crushed into powder; pulverizing; the coarse powder and the fine powder are separated by a mesh-shaped tool in order to meet the requirements of medical treatment and medicament preparation.

The instruments screened are of many kinds, as follows:

(1) and (3) manually shaking the screen: is formed by fixing a screen mesh woven by stainless steel wires, copper wires, nylon wires and the like on a circular or rectangular bamboo ring or a metal ring. Usually, the screen is also called a set screen because the sets are stacked in turn according to the size of the screen. The coarsest size is arranged on the top, the cover is arranged on the top, the finest size is arranged on the bottom, the receiver is sleeved with the medicine sieve, the medicine sieve with the required number can be taken when the medicine sieve is used, the medicine sieve is sleeved on the receiver, the cover is arranged on the medicine sieve, the medicine sieve is shaken by hands and sieved, fine powder can be prevented from flying, and the medicine sieve can be produced only in small quantity.

(2) Vibrating screen machine (also known as screen box): the box type device is a box type device which utilizes reciprocating vibration generated by an eccentric wheel to a connecting rod to drive a medicine sieve so as to vibrate the medicine sieve to sieve medicine powder. The vibrating screen has relatively great reciprocating vibration amplitude, and the powder slides on the screen surface, so that the vibrating screen is suitable for screening and analyzing non-viscous powder of plant medicine or chemical medicine. Because of the screening in the closed box, the method is also suitable for toxic and irritant medicinal powder which is easy to weather or deliquesce.

(3) Suspension type partial weight powder shifter: the medicine sieve is hung on an arched iron frame, a bias wheel is arranged on the iron frame, when the bias wheel rotates, unbalanced inertia generates shaking motion of the medicine sieve, and the medicine powder on the medicine sieve quickly falls into a receiver through sieve holes. The device has simple structure and high efficiency, and is suitable for sieving mineral medicines, chemical medicines or medicinal powder without obvious viscosity.

(4) Electromagnetic winnowing powder screening machine: the device adopts higher frequency (up to more than 200 times) and smaller amplitude (the vibration amplitude is within 3 mm) according to the electromagnetic principle, so that the sieve can quickly shake. Because the amplitude is small, the frequency is high, the shaking is fast, and the medicinal powder continuously jumps on the screen, the medicinal powder is easy to disperse and easy to pass through the screen, and the sieving efficiency is high. Is suitable for sieving medicinal powder with strong viscosity, i.e. containing oil or resin.

And (3) sieving principle: the powder needs to be vibrated continuously when being sieved, and the powder is easy to form powder blocks and is difficult to pass through sieve pores under the static state due to the influence of factors such as surface free energy and the like. When the vibration is continuously performed, the balance of various forces is broken, and the medicinal powder smaller than the sieve mesh can pass through the sieve mesh. But the vibration speed should be moderate, and too fast or too slow will reduce the sieving efficiency.

The crushing is an operation process of crushing a large solid material into fragments or fine powder with a proper degree by mechanical force. When the pharmaceutical preparation is produced, the medicine and the auxiliary materials need to be crushed to improve the uniform mixing of the compound medicine or the medicine and the auxiliary materials, increase the specific surface area of the medicine to be beneficial to the dissolution and absorption of the medicine, increase the dissolution rate of certain indissolvable medicines and improve the bioavailability of the indissolvable medicines. The formation of solid matter depends on the cohesion of the molecules. The pulverization is to partially destroy the cohesive force among the molecules of the substance by using mechanical force to make the substance into a crushed product.

The patent with publication number CN206064894U discloses a broken filter equipment, and the technical problem that this utility model will solve is to provide a broken filter equipment is used in bauxite exploitation that filters abundant, easy operation, work efficiency are high.
