Die forging chain driving type scraper submerged chain conveyor

Abstract

The invention relates to a die forging chain driving type scraper submerged chain conveyor. The die forging chain driving type scraper submerged chain conveyor comprises a machine shell, a dragging shaft, a dragging sprocket, a die forging chain, a front guide wheel, a tail guide wheel, inner guide wheels, a tension shaft, a tension sprocket and a hydraulic tension system, wherein the dragging shaft is mounted at the tail end of an oblique lifting section of the machine shell; the die forging chain is located in the machine shell and driven by the dragging sprocket; the front guide wheel is used for guiding and positioning the lower part of the die forging chain; the tail guide wheel is used for guiding and positioning the lower part of the die forging chain; the inner guide wheels are located at the two ends of a horizontal section of the machine shell and used for guiding and positioning the upper part of the die forging chain; the the tension shaft is installed on a rear section ofthe machine shell; the tension sprocket is installed on the tension shaft and used for tensioning the die forging chain; and the hydraulic tension system is installed on the rear section and used fordriving the tension sprocket to tension the die forging chain. According to the die forging chain driving type scraper submerged chain conveyor, the connection is reliable, the installation and disassembly are easy, the overhaul and maintenance are convenient, and the cost is low; and the friction is small, the rotation is flexible, the chain surface is transmitted in a contacting mode, the bearing capacity is large, and the service life is long. The die forging chain driving type scraper submerged chain conveyor can be widely used in the transportation process of ash and slag materials in coal-fired boilers.

Problems solved by technology

[0002] The internal material of the scraper slag removal machine is a mixture of water and ash. The conveying conditions are harsh, and the ash water easily enters the rotating pair of the chain, causing abrasive wear. With the development of my country's economy, the installed capacity of boilers is increasing. The output of the slag machine is also increasing; in order to achieve environmental protection and economic production, the existing circular chain chain can no longer meet the requirements, and its main shortcomings are as follows:

[0003] (1) There is a lot of pollution in the manufacture and use

The chain link is formed by welding, which will cause environmental pollution

When in use, the chain must be cut according to the required length. When the equipment is running, if there is a problem with a certain link, it needs to be replaced. Usually, gas cutting is used for destructive removal, which will also cause environmental pollution.

[0004] (2) Line contact between links, short life and low precision

In the double-chain transmission, the inconsistent wear of the chains on both sides will cause the double chains to be asynchronous, unequal in length, and cause damage to the conveying carrier or guide wheel. This is a common problem in double-ring chain conveying.

The manufacturing of the chain ring adopts welding and forming with low precision, which further aggravates the wear and unequal length

[0005] (3) Generate waste

The length of the chain is produced according to the standard. When using it, it must be cut off or added to lengthen, which not only causes waste, but also needs to increase the number of connecting links

[0006] (4) High cost

Wear resistance is one of the main performance indicators of the chain, based on the line contact, the life of the chain is low, so the average maintenance cost is higher

[0007] (5) Difficulty in overhaul and maintenance

When there is a problem with a chain link, it is usually destructively removed by gas cutting, which is not only difficult to repair and maintain, but also takes a long time. It is necessary to prepare repair tools and set up flammable and explosive gas safety protection
