Spiral sand washer

Abstract

The invention relates to the technical field of sand washers, in particular to a spiral sand washer which comprises a tank body, a sedimentation tank is arranged at the bottom of the tank body, and the opposite side walls in the tank body and the sedimentation tank are rotationally connected to spiral blades through bearings. A spiral blade cleaning assembly is correspondingly connected to the position, located on the side wall of the tank body, above each independent blade in the spiral blades, a liquid level detection assembly is arranged on the side wall of the sedimentation tank, and the liquid level detection assembly is electrically connected to the PLC control box through a wire; by means of the design, real-time monitoring of the water amount of the sedimentation tank is achieved, the problems that water overflows from the sedimentation tank, water resources are wasted, and the working environment is affected are solved, in the spiral blade cleaning process, the cleaning efficiency is improved, and the service life of the sedimentation tank is prolonged. And soil adhering to the surfaces of the spiral blades is cleaned, and the cleaning efficiency of the spiral sand washer is guaranteed.

Description

technical field [0001] The invention relates to the technical field of sand washing machines, in particular to a spiral sand washing machine. Background technique [0002] Spiral sand washing machine is a kind of sand washing machine. It mainly stirs the sand and gravel materials through the screw device in the equipment, so that the soil and water in the sand and gravel materials are mixed and discharged from the flow outlet on the equipment, while the sand and gravel materials are Under the action of the screw device, it is gradually screened and discharged from the discharge port at the top, so as to realize the cleaning and screening effect of the sand and gravel materials. The spiral sand washer has three functions of cleaning, dehydration and classification. , The bottom of the spiral sand washer tank is provided with a sedimentation tank composed of multiple groups of weir plates, and the water supply pipeline or circulating clean water supply pipeline is connected to...

Problems solved by technology

[0002] The spiral sand washing machine is a kind of sand washing machine. It mainly stirs the sand and gravel through the spiral device in the equipment, so that the soil and water in the sand and gravel are mixed and discharged from the orifice on the equipment, while the sand and gravel are in the Under the action of the spiral device, it is gradually screened and discharged from the discharge port at the top, thus realizing the cleaning and screening effect of sand and gravel. The spiral sand washing machine has three functions of cleaning, dehydration and grading. When using the spiral sand washing machine, it needs to be tilted , the bottom of the tank of the spiral sand washing machine is equipped with a sedimentation tank composed of multiple groups of weir plates, and the water supply pipeline or the circulating clean water supply pipeline are connected to the water supply pipeline through the porous plate inside the sedimentation tank to inject cleaning water into the spiral sand washing machine, ensuring The normal operation of the spiral sand washing machine, but at present the sedimentation tank in the spiral sand washing machine is not equipped with a water level detection structure, resulting in the inability to effectively control the water volume of the sedimentation tank, resulting in water overflowing the sedimentation tank, resulting in waste of water resources, and at the same time It will affect the working environment, and the spiral blades of the current spiral sand washing machine will adhere to the soil during the cleaning process, which will reduce the cleaning efficiency when rotating the sand cleaning machine
