A kind of potassium feldspar powder waste liquid recovery treatment system

Abstract

The invention provides a potassium feldspar powder waste liquid recovery and treatment system, comprising a sedimentation tank, a liquid inlet pipeline, a pumping pipeline and a sedimentation tank, the sedimentation tank is provided with a liquid inlet, a water inlet and a discharge port, and the liquid inlet and the pumping port are located on the side away from the ground of the discharge port, the liquid inlet pipe is connected to the liquid inlet and the production waste liquid discharge port, the water pumping port is connected to the pumping pipe, and the sedimentation The barrel is equipped with an inner wall scraping mechanism; the sedimentation tank is connected to the discharge port and the pumping pipeline; a discharge valve is provided at the discharge port, which can not only handle a large amount of waste liquid, but also can Scrape off the potassium feldspar powder attached to the inner wall of the sedimentation tank to increase the recovery rate of the potassium feldspar powder in the waste liquid.

Description

【Technical field】 [0001] The invention relates to the technical field of ore production equipment, in particular to a recovery and treatment system for potassium feldspar powder waste liquid. 【Background technique】 [0002] Potassium-sodium feldspar is a potassium-sodium-rich silicate mineral, which has the advantages of low melting point, long melting interval, high melt viscosity, and low fluidity. It is widely used in ceramic blanks, welding electrodes and other industrial sectors. Potassium feldspar powder minerals are not only used as raw materials for the glass industry (accounting for about 50-60% of the total consumption), but also for 30% in the ceramic industry, and the rest are used in chemical industry, glass flux, ceramic body ingredients, ceramic glazes, enamel Raw materials, abrasives, glass fiber, welding rods and other industries. Potassium feldspar powder is mainly used in glass and ceramics, and can also be used to make potassium fertilizer. Potassium fel...

Problems solved by technology

With the continuous improvement of the production process, the producer realizes that there are a large amount of extremely fine potassium feldspar powder in the above-mentioned wastewater, so the wastewater is poured into the sedimentation tank or the sedimentation bucket for recycling treatment. This treatment method has the following shortcomings: first , although the potassium feldspar powder deposited in the sedimentation tank is easy to recycle, but the storage of the sedimentation tank is too small, it is difficult to achieve a large amount of sedimentation treatment of production wastewater; second, the wastewater storage of the sedimentation tank is large, but the potassium feldspar powder is easy to adhere to the inner wall of the sedimentation tank , leading to the incomplete recovery of potassium feldspar powder; thirdly, the potassium feldspar powder attached to the inner wall of the sedimentation tank cannot be scraped off

For the third point, in the prior art, a wall brush is often provided on the inner wall of the sedimentation tank, and the wall brush is pushed by a motor or a cylinder to scrape the inner wall of the sedimentation tank. The life is short and needs to be replaced regularly; if the motor or cylinder is installed inside the sedimentation bucket, the motor or cylinder is easily affected by the humid environment in the sedimentation bucket and fails
