a sand washing machine

Abstract

The invention relates to a sand washer, and belongs to the technical field of sand production mechanical equipment. The sand washer includes a sand washing box having an internal cavity for holding washing water, wherein water flow which is evenly distributed, raises at a constant speed, and is adjustable in speed is formed in the internal cavity, and the water flow and sand in a box body form an interference sedimentation field; a discharging portion which is embedded in and fixed in the inner part of the sand washing box, and can do reciprocating rotation motion relative to the sand washing box; a water drainage portion which is arranged on the bottom of the sand washing box and communicates with the internal cavity of the sand washing box; sand containing impurities enters the internal cavity of the sand washing box, is fully washed in liquid in the internal cavity of the sand washing box, and is separated; finished sand settle to the bottom of the sand washing box, and is discharged out of the sand washing box via reciprocating rotation motion of the discharging portion so as to complete full washing and selection of the sand containing the impurities.

Description

technical field [0001] The invention belongs to the technical field of sand-making machinery and equipment, and in particular relates to a sand washing machine which uses sand and gravel to interfere with settlement in an ascending water flow. Background technique [0002] Sand and gravel are divided into natural sand and artificial sand according to the source. Natural sand includes lake sand, river sand, sea sand and mountain sand. After mining, sand and gravel usually contain a certain amount of soil, mud, stone powder, light matter, organic matter, grass roots , branches, shells, animal carcasses and other sundries cannot meet the demand for construction sand, so sand washing is required. [0003] Sand washing machine is a kind of construction machinery equipment used to remove impurities in sand products. It is used for cleaning materials in sand and gravel fields, mines, building materials, transportation, chemical industry, water conservancy and hydropower, concrete m...

AI Technical Summary

Problems solved by technology

The sand washing machine in the prior art generally adopts a drum structure, and the sand and gravel are continuously fished and washed in the water tank by the drum to achieve the purpose of cleaning. The basic principle is to put the raw sand with sundries into the water tank for soaking, stirring, Wash, and then use mechanical equipment to remove the sand and gravel. The sand washing machine in the prior art can only clean sand with a small quality. When cleaning sand with a large volume or high quality, the drum is prone to jamming. Moreover, the cleaning effect of the sand washing machine is not ideal. During the cleaning process, the attachments that were originally attached to the sand will float on the water surface, but once the sand is fished up, the attachments will stick to them again. There is a low elutriation efficiency. The separation effect of sand and mud is poor, and the equipment processing capacity is small, etc.

[0004] Several adjustment methods have been proposed for the sealing of sliding bearings in the prior art, but there are various problems: 1. CN103143450B discloses a scraper type sand and gravel floating washing machine, which includes, including a water tank, and an end is arranged in the water tank The driven wheel wound on the bottom of one side of the water tank, the other end of which is connected to the driving wheel above the side of the water tank and can perform reciprocating crawler belts. There are holes on the crawler belts for sand and gravel to fall downward. There is a scraper at the lower end of the hole. However, since the sand and gravel remain stationary relative to the track and are cleaned together by the scraper in the water tank, the cleaning efficiency is relatively low, and it is only suitable for cleaning floating objects, and cannot adapt to the dirt of sand and gravel. Sand washing operations with complex mud components; 2. CN203899725U discloses a sand washing device, including power equipment, a sand washing bucket and a stirring shaft. The lower side of the sand washing bucket below is provided with a slurry outlet, and the lower side of the sand washing bucket below the water inlet is provided with a sand outlet, and the slurry outlet is lower than the sand outlet; the stirring shaft is set in the sand washing bucket, and the stirring shaft There are connecting rods perpendicular to each other and equally spaced on the top, and the connecting rods are perpendicular to the stirring shaft; the two ends of the connecting rods are provided with scrapers perpendicular to each other, the scraper and the stirring shaft are at 45°, and the stirring shaft is connected to the power equipment; The scraper on the first connecting rod in the direction of the water inlet is parallel to the stirring shaft

This kind of sand washing device has a simple structure and low cost, but its processing efficiency is low, and the elutriation efficiency is not high, so it is not suitable for industrialized process operations
