An anti-salt sluice gate for discharging brine from salt fields

Abstract

The invention discloses a salt deposition-resistant flashboard door for discharging brine in a saltern. The salt deposition-resistant flashboard door comprises a door type frame, a flashboard slide guide, a flashboard and a chain block, wherein a vertical column of the door type frame is fixedly connected with an outer wall of a steel chute, an inner wall of the steel chute is provided with the flashboard slide guide, an end part of the flashboard is arranged on the flashboard slide guide, the top of the door type frame is provided with an upper lifting lug, the top of the flashboard is provided with a lower lifting lug, an upper lifting hook is fixed on the upper lifting lug, a lower lifting hook is fixed on the lower lifting lug, a lower end of the chain block is fixedly connected with the lower lifting hook, and an upper end of the chain block is encircles on the upper lifting hook; a surface where the flashboard is in contact with the brine is provided with a rubber air mattress which consists of at least two space air sacs, various air sacs are communicated in sequence, the rubber air mattress is provided with a flexible pipe, and the flexible pipe is provided with a valve forthe air mattress to inflate and discharge air. The salt deposition-resistant flashboard door is simple in structure, low in manufacture cost, convenient in operation and high in engineering practicability. By using the salt deposition-resistant flashboard door, the investment in fresh water supply supporting facility is conducive to being reduced, the labour intensity of operators is relieved, and the service life of the flashboard door is prolonged.

Description

technical field [0001] The invention relates to a gate for brine discharge from salt pans used in the production process of potassium chloride in salt lakes, in particular to an anti-salt gate for discharge of brine which is arranged on a steel chute for transporting brine between salt pans. Background technique [0002] At present, in the production process of potassium chloride in salt lakes, the collected brine needs to be dried by evaporation in salt pans, and the supersaturated brine produced is sent to the next level of salt pans according to the requirements of different components. Steel chutes are usually used to transport brine between salt pans to realise. In order to control the discharge of brine, the steel chute is usually equipped with a shutter door, and the opening and closing of the shutter door is realized by the inverted chain suspended on the channel steel door frame. Its main disadvantages are: due to the requirements of drying brine in salt fields, th...

AI Technical Summary

Problems solved by technology

Its main disadvantages are: due to the requirements of drying brine in salt fields, the gate is generally closed, and the brine forms a supersaturated solution during the drying process, and the brine in the area near the gate is basically stagnant, resulting in the contact surface between the gate and brine and There will be a large amount of crystalline salt precipitation and hardening in the surrounding area, making it difficult to open the gate

Before the ram is opened, a large amount of fresh water is required to wash the crystalline salt, and the ram is constantly tapped while flushing to dissolve and fall off the crystalline salt hardened on the ram, which not only requires a large amount of fresh water, but also causes saturated brine Dilution; processes such as fresh water flushing and knocking on the ram completely depend on the experience of the operator. If there is crystallized salt that has not been completely cleaned, opening the ram forcibly will easily cause partial or overall deformation of the gantry, and the ram will break away from the limit groove The steel guide rail caused the mine to run away, affecting the income of Yantian
