Description

Filter is used in intermediate production

Technical Field

The utility model relates to a medicine production facility technical field, specific theory especially relates to a filter is used in intermediate production of pharmaceuticals.

Background

The pharmaceutical intermediates are actually chemical raw materials or chemical products used in the process of synthesizing the medicines, the chemical products can be produced in a common chemical plant without production licenses of the medicines, can be used for synthesizing the medicines as long as certain grades are achieved, and need to be filtered in the production process of the pharmaceutical intermediates.

However, the existing filter for producing medical intermediates adopts the filtering method that the gravity is reduced and the substances are adsorbed by the internal filtering layer for filtering, the filtering effect obtained by the filtering method without external force is very poor, and the machine can slowly cause the filtering effect to gradually become poor because some large-particle raw materials or some accumulated powder which cannot be filtered remain in the machine after long-time filtering operation.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a filter is used in intermediate production to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a filter for producing a medical intermediate comprises a box body, wherein a feed hopper is arranged at the top of the box body, a filter box is arranged below the feed hopper and fixedly connected with the box body, two belt pulleys are rotatably arranged in the box body, a filter belt is arranged between the belt pulleys, the filter belt on the upper side penetrates through the filter box, a material collecting hopper is arranged below the filter box, and the bottom end of the material collecting hopper is connected with a material discharging pipe;

the downside filter belt installs cleaning device in the below, the bottom fixedly connected with landing leg of box, the bottom surface of landing leg is provided with the shock pad, the bottom half is connected with the waste outlet, fixed mounting has shock dynamo on the box bottom surface.

Preferably, the cleaning device comprises a rotating shaft, two ends of the rotating shaft are mounted on the side wall of the box body through bearings, and a brush is arranged on the rotating shaft.

Preferably, the width of the brush on the rotating shaft is not less than the width of the filter belt.

Preferably, the shock pad is made of rubber.

Has the advantages that: compared with the prior art, the beneficial effects of the utility model are that: the cleaning device can clean the sieve pores on the filter belt, so that impurities are prevented from blocking the sieve pores and affecting the filtering efficiency; the setting of shock dynamo can produce vibrations effect on filtering the belt, and in medical intermediate's filtration process, messenger's medical intermediate of different particle sizes is more abundant to be separated, has satisfied people to the good requirement of filter effect.
