Fully-automatic rapid separation and washing processing device for potassium nitrate

Abstract

The invention discloses a fully-automatic rapid separation and washing processing device for potassium nitrate. The device comprises a crude niter pot, wherein the lower end of the crude niter pot is provided with a water-filtering opening; the mouth of the crude niter pot is provided with a feed-dividing groove; the bottom of the feed-dividing groove is provided with a feed-dividing pipe; the bottom part of the crude niter pot is provided with a filter plate; the lower end wall of the crude niter pot is provided with a discharge pipe which is located at the upper end of the filter plate; the upper end wall of the crude niter pot is provided with a feeding pipe; a supporting frame is mounted on the mouth of the crude niter pot; the center of the supporting frame is provided with a stirring motor; the lower end of the stirring motor is connected with a stirring rod; the lower end of the stirring rod is provided with a stirrer; and the stirring motor is connected with a control box. The fully-automatic rapid separation and washing processing device for the potassium nitrate can greatly improve preparation purity and preparation speed of the potassium nitrate, does not need manual operation, does not affect health of human body, and has great practical values.

Description

technical field [0001] The invention belongs to the technical field of potassium nitrate processing, and in particular relates to a fully automatic rapid separation and washing processing equipment for potassium nitrate. Background technique [0002] The separation and washing equipment used in the existing potassium nitrate production process such as figure 1 As shown, use a square or semi-square semi-elliptical or round "hair nitrate bucket" to filter first, then wash with mother liquor and clean water, manually shovel out the washed nitrate, and then enter the re-dissolving process (the production of agricultural potassium nitrate can be directly into the drying process). This processing method has the following disadvantages: [0003] 1. Unable to mechanize production, high labor intensity, excessive consumption of water resources, incomplete separation of washed nitrate and ammonium chloride, low content of potassium nitrate in nitrate (generally only about 95%). [...

AI Technical Summary

Problems solved by technology

[0003] 1. No mechanized production, high labor intensity, excessive consumption of water resources, incomplete separation of washed nitrate and ammonium chloride, low content of potassium nitrate in nitrate (generally only about 95%)

[0004] 2. The quality of the product is unstable, and the quality of the nitrate produced by using different raw materials is completely different, which is easily limited by the raw materials

[0005] 3. It is basically pure manual labor with high labor intensity. The quality of the nitrate products made by different operators varies greatly. Due to the need for manual close-range operation, it is easy to affect human health

[0006] 4. Because a large amount of potassium nitrate crystals are mixed with ammonium chloride, they have to be shoveled out and enter the concentrated evaporation system, resulting in low production efficiency of potassium nitrate

[0007] 5. The output of the equipment is low and the floor area is large, which cannot meet the needs of large-scale production
