Problems solved by technology

[0006] Method a is easy to operate, and the cost of manufacturing and installation is relatively low. However, the two materials will be mixed, and further screening is required to separate out-of-specification materials, and the process is cumbersome.
Although the method b can separate the two kinds of stones into separate categories in the early stage, the two kinds of materials need two overflow pipes, which takes up a lot of space and costs a lot

Embodiment Construction

[0040] In view of the above-mentioned problems existing in the prior art, the embodiment of the present invention provides a overflow separation device, which includes a collection pipe and a overflow separation mechanism; wherein, the collection pipe is used to vibrate and screen aggregates for oversized materials And the overflowed grade ingredients are transported to the overflow material separation mechanism; the overflow material separation mechanism is used to separate the oversized material and the overflowed grade ingredients, and discharge the separated oversized and graded ingredients. While the material and the overflowing grade ingredients are automatically separated and discharged, it saves the layout space of the overflow pipeline.

[0041] In order to specifically illustrate the technical solutions and effects of the present invention, the present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

Abstract

The invention discloses an overflowed material screening device and asphalt stirring equipment. The overflowed material screening device comprises a collecting pipe and an overflowed material separating mechanism, wherein the collecting pipe is used for conveying overspecification materials and overflowed graded materials which are obtained after aggregates are screened in a vibration manner to the overflowed material separating mechanism, and the overflowed material separating mechanism is used for separating the overspecification materials from the overflowed graded materials, and outwards discharging the overspecification materials and the overflowed graded materials after the overspecification materials and the overflowed graded materials are separated. The arrangement space of an overflowed material pipeline is saved while the overspecification materials and the overflowed graded materials are automatically separated and discharged outwards.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to an overflow screening device and asphalt mixing equipment. Background technique [0002] The production of hot-mix asphalt concrete is the process of fully mixing asphalt and hot aggregate according to a certain formula to form a uniform mixture. The hot aggregate needs to be screened out by vibrating screens to meet the grading requirements. When there is a large difference in the grading between the raw material and the finished product, there will be too much aggregate in the individual hot aggregate compartments during production. , needs to be overflowed and discharged, because this kind of aggregate meets the gradation requirements, it can be reused after cooling; on the other hand, some aggregates are too large in size and cannot meet production needs, and this material is also called super-standard material. The overflow is discharged, and after further crushing, it is...
