Fully sealed automatic lifting device

Abstract

A fully sealed automatic lifting device is disclosed, which is an improvement for the structure of a lifting and feeding machine in high-tower production equipment for a compound fertilizer. The fully-sealed automatic lifting device comprises a storage hopper 1, a lifting hanging hopper 2, a traction device 3 and a revolution controller 31 thereof, a hanging cable 32, a hanging well 33, a discharge bin 4, a programmable controller 8, a working condition display device 9 and a frequency converter 10, wherein an automatic charging device 5 and an automatic discharging device 6 are composed of abracket, an oil pump as well as coaxial inner barrel and outer barrel respectively; the outer barrel is fixed on the bracket and provided with a guide groove on the barrel wall along an axis; an upper limit switch and a lower limit switch are installed on the guide groove; a guide block capable of stretching out of the guide groove is installed on the outer wall of the inner barrel; collision blocks corresponding to the upper limit switch and the lower limit switch are installed on the guide block; and the oil pump drives the inner barrel to move downwards during charging or discharging, and after the process is finished, the oil pump drives the inner barrel to retreat. The fully-sealed automatic lifting device has the advantages of enabling lifter to realize fully-sealed automatic operation during charging, lifting and discharging processes, solving the problems of the high dust amount of raw material and serious pollution, reducing investment and facilitating operation. The fully-sealed automatic lifting device can be used for production equipment in the industries of chemical engineering, food and the like using dusty and granular raw materials.

Description

technical field [0001] The invention relates to a lifting feeder used in high-tower compound fertilizer production equipment, in particular to a fully sealed automatic feeding device. Background technique [0002] At present, there are more than 100 sets of high-tower granulation production lines for compound fertilizers in China, and most of the powder or granular raw materials are lifted by bucket elevators or mine car elevators. Due to the characteristics of compound fertilizer production, it is difficult for the above two elevators to realize sealed transportation and automatic operation of equipment during the process of raw material loading, lifting, and unloading, resulting in large dust and serious environmental pollution during production, which is very easy to cause on-site operators. serious health hazard. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the hoist in the prior art that the raw materials are ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defects of the hoist in the prior art that the raw materials are not sealed and conveyed and the equipment requires manual operation in the loading, lifting, and unloading links, and provide a fully sealed automatic material lifting device to solve the problem of dust in the prior art. Large and serious pollution problems, realize the full sealing of raw materials in the process of loading, lifting and unloading, reduce waste of raw materials, and save costs
