Description

Efficient and environmentally friendly cleaning screen

technical field

The utility model belongs to the technical field of grain cleaning sieves, in particular to an efficient and environment-friendly cleaning sieve.

Background technique

Cleaning sieves are generally used for grain cleaning and impurity removal. There are mainly two types of cleaning sieves currently used:

First, the drum cleaning sieve is equipped with an inclined cylindrical cleaning sieve inside the shell. The screen has two layers. The inner cleaning sieve is a mesh with a larger aperture, and the outer cleaning sieve is a mesh with a smaller aperture. Large debris is blocked by the inner cleaning sieve, grain and small debris enter between the two cleaning sieves, and after being cleaned by the outer cleaning sieve, the grain remains between the inner cleaning sieve and the outer cleaning sieve, and the small debris falls on the outer layer Cleaning the outside of the sieve, the cleaning sieve has the advantages of large processing capacity and high processing efficiency, but also has the following disadvantages: 1. The cleaning effect is poor, and the grain contains more impurities. 2. The mesh is two layers, which is inconvenient to maintain. It is not easy to clean up after clogging. 3. The mesh has two layers, and the food is easy to remain between the two layers of mesh. In northern China, the grain is easy to condense in winter, and it is easy to burn out the motor when starting again.

Its two, the vibrating screen, is provided with inclined vibrating sieve sheet on the frame body, and the sieve sheet is upper and lower layers, and the vibrating screen has the advantage of cleaning up. But there are also the following disadvantages: 1. The sieve of the vibrating screen has two upper and lower layers, and the distance between the two layers of sieves and between the sieve and the frame is small. When the sieve is blocked, it is difficult to clean; 2. The processing capacity is small , low work efficiency.

Utility model content

The problem to be solved by the utility model is to provide an efficient and environment-friendly cleaning sieve with high cleaning efficiency, good cleaning effect, convenient cleaning of sieve sheets and long service life.

In order to solve the above problems, the technical solution adopted by the utility model is: comprising a frame body, a drum screen is arranged above the frame body, the drum screen is placed on the frame body obliquely, and a There is a shell with a feed inlet at the upper end and a strip-shaped discharge outlet at the lower end. The feed inlet is located on the high-end side of the trommel screen. An inclined vibrating screen is arranged below the strip-shaped discharge opening. A grain outlet is arranged above the bottom of the vibrating sieve, and a miscellaneous outlet is arranged below the vibrating sieve. The drum sieve has one layer of sieves, and the vibrating sieve has one layer of sieves.

Its additional technical features are:

A wind separation and dust removal mechanism is arranged above the grain outlet.

Compared with the prior art, the high-efficiency and environment-friendly cleaning screen provided by the utility model has the following advantages: First, because it includes a frame body, a drum screen is arranged above the frame body, and the drum screen is placed obliquely on the On the frame body, a casing with a feed inlet at the upper end and a strip-shaped discharge opening at the lower end is provided around the drum screen. The feed inlet is located on the high-end side of the drum screen. An inclined vibrating screen is arranged below the mouth, a grain outlet is arranged above the bottom of the vibrating screen, and a miscellaneous outlet is arranged under the vibrating screen. The sieve of the drum sieve is one layer, and the vibrating screen The sieve sheet is one layer. After the grain to be cleaned enters through the feed inlet, it is first cleaned at a high speed through the drum sieve, and the large impurities that are larger than the sieve hole are left in the sieve cylinder, and the grain and small impurities enter the vibration through the strip-shaped discharge opening. On the top of the sieve, after being screened by the vibrating sieve, the small trash falls to the bottom of the vibrating screen, and the grain is cleaned. Since the large trash has been screened out in the drum sieve, the grain falling on the vibrating screen does not have large trash that occupies a large space. The cleaning efficiency of the vibrating screen is improved. The drum screen and the vibrating screen have one layer. When the screen is blocked, it is easy to clean, and the grain in the drum screen is easy to fall, and will not remain in the drum screen, and will not damage the motor. damage, prolonging the service life; second, due to the air separation and dust removal mechanism is arranged above the grain outlet, the uncleaned dust and hair must be processed by the wind separation and dust removal mechanism in the cleaning process, so as to avoid entering the air Pollution to the air, effectively reducing the content of PM2.5 in the air.
