Sand filtering device for building

Abstract

The invention discloses a sand filtering device for a building. The sand filtering device for the building comprises a machine body, a feeding hopper is rotationally connected to the top of the machine body, a conical screen is fixed to the bottom of the feeding hopper, an impurity storage cavity is fixed to the bottom of the conical screen, the surface of the impurity storage cavity is rotationally connected with the bottom of the machine body, a spiral blade is located in the conical screen and fixed to the bottom of the feeding hopper, a cleaning device is arranged on the surface of the conical screen, a pressing device is arranged on the inner wall of the machine body, a flow guide plate is fixed to the inner wall of the machine body and close to the bottom of the machine body, and a filter sieve is fixed to the bottom of the inner wall of the machine body. The invention relates to the technical field of building equipment. According to the sand filtering device for the building, the purpose of removing impurities in time is achieved, the impurities can be removed in time, impact generated after the impurities are thrown out is avoided, the service life of equipment is prolonged, meanwhile, wet sand balls are scattered in time, filtering is facilitated, and the working efficiency and the using performance are improved.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a construction sand filtering device. Background technique [0002] Construction site, also known as construction site, construction site, referred to as site, is a place where construction projects are being developed and civil engineering is being carried out. The scope is often closed by hoardings, barbed wire or walls to restrict the entry and exit of personnel, materials, machinery and vehicles , the most common thing in construction sites is sand, which is widely used. In addition to being used for construction, road construction, filtration, breeding and beautification, and as a speed-capacitant for smelting, it is also the main material for making glass. Above all, sand is one of the important components in concrete. In construction, general sand is often purchased as a building raw material, which needs to be filtered. [0003] At present, most of the sa...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a sand filter device for construction, which solves the problem that most construction sites currently use artificial filtering methods for sand filtering, and the sand is thrown onto the filter net, the filtering speed is slow, the filtering quality is low, and the need for It consumes a lot of labor, and at the same time, the sand will be mixed with large particles of stones, stones and other debris, which cannot be removed in time, which will affect the filtration efficiency. At the same time, after being thrown onto the filter net, it will generate a large impact force, which will deform the filter screen , or even damaged, which affects the service life, and when it encounters wet sand, it will stick together and form sand clusters, which further affects the filtration efficiency and reduces the performance problem
