Drying and sieving all-in-one machine

Abstract

The invention discloses a drying and sieving all-in-one machine. The all-in-machine comprises a rack (1), wherein the rack (1) is provided with a lower box body (2), at least one middle box body (3) and an upper box body (4) which are fixedly connected from bottom to top in sequence, wherein the lower ends of the middle box bodies are all provided with sieves (12), and the two adjacent middle box bodies are distributed according to sieve holes of the upper box body larger than those of the lower box body; the lower box body (2) is provided with at least one air inlet which is connected with a hot air transmitting device, and the lower box body (2) is connected with a vibrator (5); the upper box body (4) is provided with at least one material inlet (8), and is also provided with an air outlet (9); the middle box bodies are provided with material outlets which are provided with material feeding channels (10). According to the drying and sieving all-in-one machine provided by the invention, particle materials can be sieved in the drying process, the energy consumption is reduced, and the pollution is alleviated.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to an integrated drying and screening machine. Background technique [0002] In the fields of food, medicine, pesticides, chemical fertilizers, pellet feed, etc., it is often necessary to dry and sieve products. Sieving refers to the process of separating different particles by size with one or more sieves. Commonly used sieving The methods include wet sieving and dry sieving. At present, one of the commonly used methods for drying and sieving industrial particles is to obtain dry products through vibrating fluidized bed drying, and then sieving through vibrating sieves. This becomes the first drying method. There are two post-screening processes. In order to keep the wet product particles in a floating fluidized state on the sieve plate in the machine, and to overcome gravity, a large-flow blower and induced draft fan must be selected, so that a larger-power heater and b...

[0002] In the fields of food, medicine, pesticides, chemical fertilizers, pellet feed, etc., it is often necessary to dry and sieve products. Sieving refers to the process of separating different particles by size with one or more sieves. Commonly used sieving The methods include wet sieving and dry sieving. At present, one of the commonly used methods for drying and sieving industrial particles is to obtain dry products through vibrating fluidized bed drying, and then sieving through vibrating sieves. This becomes the first drying method. There are two post-screening processes. In order to keep the wet product particles in a floating fluidized state on the sieve plate in the machine, and to overcome gravity, a large-flow blower and induced draft fan must be selected, so that a larger-power heater and booster must be selected. Equipped with a first-stage cyclone separator and a second-stage pulse bag filter (other types of dust collectors can also be used), the production process is complicated, the plant and equipment investment is large, the energy consumption is high, the production efficiency is low, and the required operators The number increases accordingly, and the cost of human resources increases accordingly, resulting in a decrease in the profit margin of the enterprise
