Automatic feeding system of roller kiln

Abstract

The invention discloses an automatic feeding system of a roller kiln. A steel rack is arranged above the automatic turning line of one side of the inlet of the roller kiln, the steel rack is provided with a large hopper, three weighing units are arranged below three support lugs of the large hopper and fixed on the steel rack, a variable frequency speed regulating weighing spiral is arranged at the lower outlet of the large hopper, a butterfly valve is arranged at the outlet of the weighing spiral, the large hopper, weighing units, weighing spiral, butterfly valve and a weighing control system jointly form a metering and weighing system, and the metering and weighing system is arranged in an automatic control system of the roller kiln. A small hopper is arranged below the outlet of the weighing spiral, a butterfly valve is arranged below the small hopper, and the small hopper can hold the loading amount of one crucible at one time. A synchronous cylinder is arranged before the automatic turning line, a press plate with four claws is connected with the downside of the cylinder push rod, and the synchronous cylinder and the press plate with claws are arranged on the steel rack. The automatic feeding system of the roller kiln meets the automatic loading and drying requirements of the roller kiln crucible and enables the overall automatic level of the roller kiln to be improved, and the automatic feeding system of the roller kiln is easy and convenient to operate and high in weighing precision.

Description

technical field [0001] The invention relates to an automatic feeding system for drying materials in a roller kiln with an automatic rotary line in the field of powder drying. Background technique [0002] In the production of chemical industry, electronics, metallurgy, building materials, rare earth and lithium battery raw materials, many products are dry solid powder, and the semi-finished products are mostly wet materials containing a certain amount of liquid, which need to be dried to obtain products. There are many ways to dry powder, one of which is to use roller kiln to dry materials. The length of the roller kiln is generally 50 meters to 100 meters. Put the wet material into the crucible, put it on the pallet, and send it into the roller kiln. Through the process of heating, drying, cooling, and cooling (outside the kiln), the obtained Product that needs to be dried. The roller kiln is equipped with electric heating rods, which are arranged horizontally up and down...

AI Technical Summary

Problems solved by technology

The main problem is that when the wet material falls into the crucible below due to gravity after automatic weighing, the phenomenon of material collapse due to inaccurate automatic weighing is out of tolerance and the phenomenon of material collapse is not effectively controlled, and the wet material will overflow and spill out of the crucible to cause leakage. The situation of raw materials will cause waste, increase production cost, and reduce yield; after wet materials are successfully loaded into the crucible, due to the angle of repose of the materials themselves, there will be a heap phenomenon like a hillside on the upper surface. When the wet materials are in the crucible When the automatic rotary line enters the roller kiln for drying, due to the unevenness of the wet material in the crucible, the phenomenon of impermeable drying and sugar core will appear in the middle high place, which seriously affects the product quality and output.
