Embodiment 1

[0030] A double-layer vibrating screen for an asphalt mixing plant, comprising a vibrating screen main body, a fine-mesh stainless steel plate screen 7 and a coarse-mesh stainless steel plate screen 6 in the vibrating sieve main body, and the inner wall of the vibrating screen main body is symmetrically arranged along the opening direction of the fine-mesh stainless steel plate screen 7 There are two groups of parallel slide rails 18, and the two groups of slide rails 18 are respectively arranged above the fine-mesh stainless steel plate screen 7 and the coarse-mesh stainless steel plate screen 6. The slide rails 18 are all provided with slide boxes 8 that independently slide and cooperate with them. Sliding box 8 is connected by the first slide beam 11, the second slide beam 14, and the first slide beam 11 is connected with the shovel plate 10 that contacts with the fine-mesh stainless steel plate screen 7 or the coarse-mesh stainless steel plate screen 6, and the second slide ...

Embodiment 2

[0033] This embodiment is further optimized on the basis of implementation 1, specifically:

[0034] The main body of the vibrating screen includes a base 1, on which a screen box 2 is connected through a vibration isolation spring 3, a feeding box 4 connected to it is provided on one side above the screen box 2, and a driving coarse mesh is provided on the other side above the screen box 2. The first vibration motor 5 and the second vibration motor 19 of stainless steel plate screen 6 and fine mesh stainless steel screen 7 vibrate. The plate screen 7 is arranged below the coarse-mesh stainless steel plate screen 6 . The feeding box 4 feeds the material, and the input raw materials enter the coarse-mesh stainless steel screen 6, the first vibration motor 5 drives the coarse-mesh stainless steel screen 6 to vibrate, and the large particles are discharged through the opening on one side of the coarse-mesh stainless steel plate, and some raw materials pass through the coarse-mesh...

Abstract

The invention relates to the technical field of vibrating screen equipment, and discloses a double-deck vibrating screen for an asphalt mixing plant. The double-deck vibrating screen comprises a vibrating screen main body, a fine-mesh stainless steel plate screen body and a coarse-mesh stainless steel plate screen body in the vibrating screen body; two groups of parallel sliding rails are symmetrically arranged on the inner wall of the vibrating screen main body in the opening direction of the fine-mesh stainless steel plate screen body and are arranged above the fine-mesh stainless steel plate screen body and the coarse-mesh stainless steel plate screen body separately; sliding boxes matched with the sliding rails in a sliding mode are arranged on the sliding rails, and the opposite sliding boxes are connected through a first sliding beam and a second sliding beam; the first sliding beam is connected with a shovel plate which makes contact with the fine-mesh stainless steel plate screen body or the coarse-mesh stainless steel plate screen body; the second sliding beam is connected with a brush which makes contact with the fine-mesh stainless steel plate screen body or the coarse-mesh stainless steel plate screen body; and the brush is located on the side, away from an opening of the fine-mesh stainless steel plate screen body, of the shovel plate. According to the double-deckvibrating screen, by means of the design, the problem that for an existing vibrating screen for an asphalt mixing plant, asphalt adsorbed on the surface of the vibrating screen is not liable to be cleared quickly can be solved.

Description

technical field [0001] The invention relates to the technical field of vibrating screen equipment, in particular to a double-layer vibrating screen for an asphalt mixing plant. Background technique [0002] The vibrating screen is a kind of filtering mechanical separation equipment used for mud solid phase treatment. The thickness of the screen is expressed by mesh. Generally, the mesh below 50 mesh is coarse mesh, and the mesh above 80 mesh is fine mesh. The vibration has multiple points. Advantages: Due to the strong vibration of the screen box, the phenomenon of material blocking the screen hole is reduced, so that the screen has high screening efficiency and productivity; the structure is simple, and the screen surface is convenient to replace; the power consumption per ton of material for screening is small. [0003] In the asphalt preparation process of the asphalt mixing plant, a vibrating screen is used. The main principle is to use the vibration of the vibrating scr...
