Embodiment Construction

[0015] The following will be attached Figure 1-4 The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0016] The present invention provides a trommel screen through improvements, such as Figure 1-4 As shown, it can be implemented as follows; including a frame system 1, a drum shell 2, a rotating drum screen 3, and a motor 5. The drum shell 2 is integrally inclined and fixed on the frame 1 at a certain angle, and the rotating drum screen 3 is placed on the whole In the drum shell 2, the drum screen 3 is made of stainless steel, and there are m...

Abstract

The invention discloses a drum screen. The drum screen is characterized in that the drum screen comprises a rack system, a drum shell, a drum screen body and a motor; the drum shell is obliquely fixed to a rack at a certain angle on the whole, the drum screen body is arranged in the drum shell on the whole and made of stainless steel, and a plurality of sieve meshes are formed in the drum screen body; and a coupling piece A is fixed to the rotating end of the drum screen body, the transmission end of the motor is connected with a speed reducer, and the output end of the speed reducer is connected with a coupling piece B. The drum screen is mainly composed of a drum device, the speed reducer, the motor, an intra-screen cleaning device, bottom supports, a sealing cover, a discharging port, a feeding port and the like. A spline type coupling special for the drum screen is composed of the coupling piece A and the coupling piece B, the structure is simple, and manufacturing and mounting are convenient; and the connecting strength is high, and normal operation of the drum screen is guaranteed.

Description

Technical field [0001] The invention relates to a drum device, in particular to a drum screen. Background technique [0002] The trommel screen is a kind of beneficiation equipment that performs classification processing according to the particle size of the material, and is also called a trommel screen. It is commonly used in the classification and screening of medium and fine-grained materials to improve the quality of materials. [0003] Roller screens are widely used in electric power, mining, metallurgy, building materials, chemical and other production industries. It is often used for the classification of refractory materials, coal, sandstone blocks, and the screening of coal, coke, white ash, placer gold and other viscous materials to make the product structure more even to meet production needs. The existing trommel screen has the following shortcomings: complex structure, high energy consumption, and low screening efficiency; therefore, it needs to be improved. Summar...
