Description

TECHNICAL FIELD

[0001] The utility model relates to the drying field, concretely relates to a material liquid drying machine. BACKGROUND

[0002] The drying machine is a device that removes water in material liquid through heat energy or mechanical action. The drying machine in the prior art is mainly divided into a disc type drying machine and a roller type drying machine. The disc type drying machine dries material liquid through a heating disc, but since the drying contact surface of the material liquid is only the upper surface of the heating disc, the heat exchange area utilization rate is low, and the drying production capacity is low. When the roller type drying machine is in operation, the material liquid that needs to be dried is flowed from a high tank into a receiving tank of the drying machine, and the material liquid is thinly attached to the surface of the roller through a membrane distribution device. The heat transfer area is small, and the processing capacity is low. In addition, for high-salt, high-viscosity and easy-fouling material liquid, the drying machine in the prior art is prone to crystallization and fouling, thereby reducing the drying efficiency and effect. For example, the roller type mother liquid drying device disclosed in the Chinese utility model patent CN222150907U includes a box body, a spacing baffle, a roller, a driving assembly, a scraping mechanism and a mother liquid inlet assembly. The spacing baffle is arranged in the box body to divide the box body into a salt separation chamber and a collection chamber. The roller is located in the salt separation chamber and rotationally connected with the box body. The power output end of the driving assembly is fixedly connected with the roller. The scraping mechanism includes a support plate, a guide assembly, an adjusting assembly and a scraper. The support plate is fixedly installed on the spacing baffle. The guide assembly is slidingly connected to the support plate. The adjusting assembly is installed on the spacing baffle. The adjusting end of the adjusting assembly is connected with the guide assembly to adjust the sliding position of the guide assembly relative to the support plate. The scraper is elastically connected to the guide assembly. The scraping part of the scraper abuts against the outer periphery of the roller. The mother liquid inlet assembly includes a mother liquid inlet pipe and a spray head. The liquid outlet end of the mother liquid inlet pipe is located in the salt separation chamber. The spray head is arranged at the liquid outlet end of the mother liquid inlet pipe, and the spray end of the spray head is arranged towards the outer wall of the roller. The foregoing patent dries the material liquid sprayed on the inner wall of the roller through hot gas. Due to the limitation of the surface area of the inner wall of the roller, the heat exchange area is small, and the drying treatment efficiency is low. For example, the high-efficiency and energy-saving mother liquid drying evaporator disclosed in the Chinese utility model patent CN218485167U includes an evaporator. The evaporator is internally provided with a heating chamber and an evaporation chamber. The evaporation chamber is located above the heating chamber. The heating chamber is provided with an inlet and an outlet. The evaporation chamber is provided with an outlet. The heating chamber is internally provided with a heat exchange cylinder. The heat exchange cylinder is rotationally installed in the heating chamber. The foregoing patent adds the heat exchange cylinder to achieve the purpose of uniform heating, but is also limited by the internal surface area of the heating chamber. The heat exchange area is still small, and the drying treatment efficiency is low.
