Screening device for producing refractory material

Abstract

The invention discloses a screening device for producing a refractory material. The screening device comprises a shell. A storage bin is arranged at the top end of the shell. A first screen frame is arranged at the top end in the shell, a coarse screen is fixedly installed at the upper end of the inner side of the first screen frame, and a fine screen is fixedly installed at the lower end of the inner side of the first screen frame. A second screen frame is arranged at the bottom end in the shell, an efficient screen is arranged on the inner side of the second screen frame, and a rotary cam is arranged at the bottom end of a drive motor. According to the screening device for producing the refractory material, through cooperation of the coarse screen, the fine screen and the efficient screen, an exciter works to drive the first screen frame to vibrate through a first vibrating spring and a first telescopic supporting rod; through cooperation of the coarse screen and the fine screen, the material is screened twice, and the screening effect is improved; and the drive motor works to drive a propelling ring groove through the rotary cam to drive the second screen frame to work in a reciprocating manner so that the efficient screen can finely screen the material, the screening effect is improved, and the use requirements of the refractory material are met.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a screening device for producing refractory materials. Background technique [0002] Screening operation is an indispensable part of refractory material production. There are many types of screening equipment in refractory material factories. Generally, there are two types of fixed sieves and movable sieves. The moving sieves mainly include shaking sieves, rotary sieves and vibrating sieves according to their movement modes. Due to the simple structure, high screening efficiency and strong production capacity, the vibrating screen is the most widely used, but in the existing screening device, for example, the utility model patent with the application number It is rotatably installed on the bracket. The screen drum includes a screen and two side plates. The screen is rolled into a cylindrical shape and has two openings on both sides. The two side plates are respectively fixed ...

[0002] Screening operation is an indispensable part of refractory material production. There are many types of screening equipment in refractory material factories. Generally, there are two types of fixed sieves and movable sieves. The moving sieves mainly include shaking sieves, rotary sieves and vibrating sieves according to their movement modes. Due to the simple structure, high screening efficiency and strong production capacity, the vibrating screen is the most widely used, but in the existing screening device, for example, the utility model patent with the application number It is rotatably installed on the bracket. The screen drum includes a screen and two side plates. The screen is rolled into a cylindrical shape and has two openings on both sides. The two side plates are respectively fixed at the two openings of the screen and closed. Opening, although the patent has a certain screening function, but in actual use, the screening efficiency is low, and the quality of the screened is poor, which cannot meet the needs of refractory materials
