Chain plate conveying coal ball heat conduction oil dryer

Abstract

A chain plate conveying coal ball heat conduction oil dryer belongs to the field of drying equipment. The chain plate conveying coal ball heat conduction oil dryer comprises a heat insulation outer shell, a chain plate conveying mechanism, a feeding conveying belt, a discharging opening, a heating device and a waste heat using device. The chain plate conveying mechanism comprises a double-driving chain structure, a matched chain wheel, a bearing chain plate and a guiding sliding track. The bearing chain plate is a hollow-out structure formed by a frame and a grid bar and is located on a chain shaft in a hinge mode. The guiding sliding track is divided into an upper sliding track part and a lower sliding track part which have the same structure sequence. Each part is divided into a horizontal section, a V-shaped blanking section and an arc groove-shaped turning section which are connected in sequence. A falling zone corresponds to a lowering edge section of each V-shaped blanking section of the guiding sliding part. The heating device is connecting heat conduction oil furnace heat conduction calandrias which are distributed above and below a conveying interface formed by the bearing chain plate. An improved double-chain strip plate type conveyor is used, a high-efficiency heat conduction oil furnace is used as a heat source, a controllable heat conduction oil pipe composite layer distribution structure is used for improving the heating effect, and the effects of small space size, energy saving and environment protection are achieved.

Description

technical field [0001] The invention belongs to the field of drying equipment, and relates to chain-plate conveying drying equipment, in particular to a chain-plate conveying briquette heat-conducting oil dryer. Background technique [0002] Now in the vast rural areas with vast territory, it is unrealistic to completely cancel coal burning. In addition to heating in winter, coal and carbon are mostly used as main fuels in the processing and production of agricultural and sideline products. Coal and carbon are prone to smoke during combustion, and polluting the environment is also a last resort. Therefore, it is an effective measure to use industrialized means to desulfurize anthracite and add an appropriate amount of catalyst to make environmentally friendly briquettes, which can reduce the excitation calorific value, solidify polluted gases and ash, and have little environmental pollution. , is gradually becoming the mainstream product of rural life fuel. In briquette f...

AI Technical Summary

Problems solved by technology

However, the free-fall transfer mode adopted by the transport carrier is very unsuitable for briquettes with high water content and loose structure, which will cause a large amount of crushing

The existing structure is applied in the briquette drying equipment, and there are the following problems: (1) The chain plate and the guide rail are matched during the unloading process, and the chain plate is directly turned downward to unload without buffering settings, which is likely to cause high moisture content. The briquettes are broken when they fall and the briquettes are piled up on the chain plate, which leads to a decrease in the qualified rate of briquettes and a decrease in drying efficiency; (2) The chain plate directly turns around the sprocket wheel, causing the impact force of the chain plate to directly act on the chain plate conveying device (3) To make the chain plate have enough loading area and conveying efficiency, the chain plate must ensure sufficient width, so the sprocket must be large enough to cause the chain plate conveyor to The increase in the vertical height of the drying equipment leads to a large volume of drying equipment and a large volume of drying space to be heated, which intensifies the energy consumption of the drying equipment and increases the manufacturing cost
