Sand stone washing device used for concrete machining

Abstract

The invention discloses a sand stone washing device used for concrete machining and belongs to the field of building material machining mechanical equipment. A sand stone feeding mechanism, a sand stone falling mechanism, a sand stone washing mechanism and a washing water circulating mechanism are fixedly arranged on one side of a sand stone guiding and conveying support in sequence from top to bottom. A sand stone conveying belt is horizontally connected to a material conveying rotating roller in a winding manner. A sand stone dispersing pipe is vertically and fixedly arranged on the sand stone guiding and conveying support on the lower side of the end portion of a material guide oblique plate. Reciprocating falling plates are vertically arranged on the two sides of fixed falling connecting plates on the two sides below the sand stone dispersing pipe. A washing screen is arranged on the lower side of the falling support obliquely. A fixed washing water pipe is fixedly arranged on thelower side of the falling support on the upper side of the middle portion of the washing screen horizontally. A fixed water collecting groove is horizontally and fixedly formed in the lower side of the washing screen. The sand stone washing device is reasonable in structural design, sand stones used for machining the concrete can be washed rapidly and efficiently in the conveying process, the machining automation degree is high, and the requirement of machining and using is met.

Description

Technical field [0001] The invention belongs to the field of building material processing machinery and equipment, and in particular relates to a sand and gravel cleaning device for concrete processing, which is mainly applied to the production and preparation of concrete. Background technique [0002] Concrete refers to a collective term for engineering composite materials that are aggregates cemented into a whole by cementitious materials. Concrete is one of the most important contemporary civil engineering materials. It is composed of cementitious materials, granular aggregates, water, and when necessary The added admixtures and admixtures are prepared in a certain proportion, and are uniformly stirred, compacted, formed, and cured to form an artificial stone. The concrete has the characteristics of abundant raw materials, low price, and simple production process, so the amount of concrete is increasing. The larger, the concrete also has the characteristics of high compressive...

AI Technical Summary

Problems solved by technology

In the process of concrete production and configuration, sand and gravel are indispensable aggregates for the preparation of concrete. A reasonable proportion of sand and gravel and high-quality sand and gravel are the prerequisites for the preparation of high-quality concrete. The sand and gravel used for the preparation of concrete requires cleanliness Does not contain impurities, so that the quality of concrete can be guaranteed. The existing sand and gravel often contain some harmful impurities, such as mica, clay, silt, silt, etc., which adhere to the surface of the sand and gravel, hindering the bonding of cement and sand and gravel. Reduce the strength of concrete and increase the water consumption of concrete at the same time, thereby increasing the shrinkage of concrete, reducing frost resistance and impermeability, and some organic impurities, sulfides and sulfates adhering to the surface of sand and gravel are harmful to cement. It has corrosion effect, so before using sand and gravel to prepare concrete, the impurities on the surface of the sand and gravel must be cleaned. The existing sand and gravel cleaning device has a complicated structure and troublesome operation. Sand washing machine and drum sand washing machine clean the sand and gravel, resulting in the close contact between the sand and gravel during the entire washing process of the sand and gravel, it is difficult to achieve efficient and sufficient rapid transmission of sand and gravel vibration, and it cannot be transported During the cleaning process, the vibration is sufficient and scattered, which makes it difficult to remove the impurities that are firmly adhered to the surface of the sand and gravel. The sand and gravel cannot be fully cleaned, which affects the quality of concrete prepared from sand and gravel, and cannot meet the needs of processing and use.
