Description

TECHNICAL FIELD

[0001] The utility model relates to borax production instrument technical field, specifically is a kind of borax production is used crystallization, dehydration device. BACKGROUND

[0002] The dehydration drying device in borax production plays a vital role in the whole production process. Its main function is to remove the crystal water in borax, convert it into a product with low water content, ensure that the product has better storage, transportation stability and performance to meet different industrial needs. The structure of the dehydration drying device usually includes feeding device, heating system, drying chamber, moisture removal device, cooling device and discharge device. The feeding device uniformly sends the water-containing borax raw material into the drying system. The heating system provides heat source by steam, electric heating or gas, etc. to heat the borax in the drying chamber and promote water evaporation. The water is evaporated into water vapor in the drying chamber through the action of air flow and heat. The water vapor is promptly discharged through the moisture removal device. The cooling device cools the dehydrated borax to an appropriate temperature for subsequent packaging and transportation. The discharge device is responsible for timely delivery of the dried borax. For example, the dehydration device for borax production disclosed in the authorized announcement No. CN216703405U includes a crystallization tank. The upper surface of the crystallization tank is connected with a liquid inlet. A cooling assembly is arranged inside the crystallization tank. A discharge pipe is connected to the lower end of the crystallization tank. A valve is arranged inside the discharge pipe. A dehydration tank is connected to the lower end of the discharge pipe. A control box is fixedly installed on the outer surface of the dehydration tank. A collection box is inserted into the dehydration tank. A air-drying assembly is arranged inside the dehydration tank. The cooling assembly includes a first motor fixedly installed on the upper surface of the crystallization tank. It can quickly cool the borax solution to precipitate borax crystals and scrape off the borax crystals adhered to the inner wall of the device for easy removal, thereby saving time and materials. However, the dehydration and crystallization process mainly relies on the air-drying assembly to dry the borax crystals in the dehydration tank. Since the borax crystals in the dehydration tank are in a stacked state, the hot air produced by the air-drying assembly mainly acts on the upper part of the borax crystal stack. The flow of hot air is limited by the density of the material and the structure of the stacked layer in the lower and inner parts of the stack. This stacking state makes it difficult for hot air to penetrate into the interior of the stacked layer, thereby affecting the drying efficiency of the internal borax. The borax in the upper part of the stack can be quickly dried, while the borax in the lower part is dried slowly due to insufficient contact with hot air, resulting in uneven drying and dehydration.
