Screening device convenient to clean and used for preparing degradable building materials

Abstract

The invention discloses a screening device convenient to clean and used for preparing degradable building materials. The screening device comprises a first-stage screening chamber, a first-stage screening chamber inlet, a first inclined block, a first-stage screening chamber outlet, a first rotating shaft, a first-stage screening basket, a second-stage screening basket, a third-stage screening basket, a first screen, a first motor, a refining chamber, a refining chamber inlet, a refining chamber outlet, a second motor, a second inclined block, a second rotating shaft, a smashing blade, a second screen and the like. The screening device is convenient to install and complete in function, multiple screening devices are arranged, screening can be carried out many times, the working efficiencyis high, the screening device is reasonable, simple and low in production cost, and loading and unloading are convenient to clean. All the components of the screening device do not need to be machinedcomplexly, the production cost is low, and the screening device is suitable for large-scale popularization. Buffer rods are arranged, the left side and the right side of a screen frame can have buffer performance, and therefore when the screen frame ascends and descends, the screen frame cannot shake, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of screening devices, in particular to a convenient cleaning screening device for preparing degradable building materials. Background technique [0002] Building materials are various materials used in construction engineering. There are many kinds of building materials, which can be roughly divided into: (1) Inorganic materials, which include metal materials (including ferrous metal materials and non-ferrous metal materials) and non-metal materials (such as natural stone, burnt earth products, cement, concrete and silicate products) Wait). (2) Organic materials, which include plant materials, synthetic polymer materials (including plastics, paints, adhesives) and asphalt materials. (3) Composite materials, including asphalt concrete, polymer concrete, etc., are generally composed of inorganic non-metallic materials and organic materials. [0003] Screening is the operation of dividing mixed materials wit...

Problems solved by technology

[0005] The purpose of the present invention is to provide a convenient cleaning degradable screening device for building material preparation in order to solve the above problems, which solves the problem that most of the building material screening devices on the market currently have only one layer of screening plate, and the screening level Less, it is difficult to meet the use requirements, the device is not convenient for loading and unloading, it is inconvenient to clean, and the problem of reducing work efficiency
