Random material washing sieve

Abstract

The invention discloses a random material washing sieve, belonging to a stone material separating sieve in the field of building construction. A water spraying pipeline is horizontally arranged above the front part of a sieve body; a primary water guide plate and a secondary water guide plate are arranged on the sieve body; a water permeable sieve, a guide plate, a water dropping port and a waste port are arranged in a material dropping cabin; the sieving and washing of gravels are synchronously performed; the water and the gravels are differently oriented at the same time; and automatic separation of the water and the gravels is realized at last. According to the random material washing sieve disclosed by the invention, gravel washing equipment does not need to be arranged, a working procedure of washing the gravels solely is obviated, the water content of the gravels is complemented, the interfaces of cementing bodies of the gravels and cement are improved, and the concrete strength is enhanced. The random material washing sieve has the advantages of a simple structure, small investment, high efficiency, energy saving effect, emission reduction and the like, and has good application prospect and popularization values.

Description

technical field [0001] The invention relates to a solid material separation screen, in particular to a stone material separation screen used in building construction. Background technique [0002] In building construction, the quality of cement concrete is related to the quality of building construction. The water content in cement concrete, the proportion of crushed stone and cement, and the cleanliness of crushed stone are the key factors affecting the quality of cement concrete. At present, the general cement concrete mixing equipment directly mixes the crushed stone according to the ratio, and the dust adheres to the surface of the stone material, which has a great influence on the quality of the concrete. In addition, the cement concrete used in some construction projects requires the cleaning of crushed stones. Generally, the site cleaning method is adopted, which requires additional equipment, manpower investment and energy consumption, and adds a secondary handling ...

Problems solved by technology

At present, the general cement concrete mixing equipment directly mixes the crushed stone according to the ratio, and the dust adheres to the surface of the stone material, which has a great influence on the quality of the concrete.

In addition, the cement concrete used in some construction projects requires the cleaning of crushed stones. Generally, the site cleaning method is adopted, which requires additional equipment, manpower investment and energy consumption, and adds a secondary handling link to the crushed stones, which is affected by weather and the environment. , the washed gravel will cause secondary pollution in the process of transporting and stacking on the site. At the same time, the water content of the stacked gravel is not uniform, making it difficult to control the subsequent mixing water consumption, thus affecting the quality of cement concrete.
