Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing.

[0022] figure 1 A chain conveyor 10 (hereinafter referred to as conveyor 10 ) according to the invention is schematically shown. Such as figure 1 As shown, the conveyor 10 includes a chain 11 and a wheel set including a plurality of wheels for supporting and driving the chain 11 . A hopper 12 is movably arranged on each link of the chain 11, so as to load materials into the hopper 12 and realize automatic unloading of materials. These materials can be, for example, activated carbon. In order to convey materials between positions of different heights, the chain 11 is generally arranged in a "Z" shape in the vertical direction, which can be realized by properly arranging the wheels. Such as figure 1 As shown, chains 11 are connected end to end to form a closed loop. The drive wheel 13 is arranged at the first position on the upper part, the steering wheel 14 is arranged...

Abstract

The invention relates to a chain conveyor and a chain breaking protection method. The conveyor includes an endless closed chain, a wheel set that drives the chain to circulate, a speed measuring device that detects the speed of each wheel in the wheel set, and a processor that controls the rotation of the wheel set according to the speed signal sent by the speed measuring device. The set includes a first wheel arranged at a low position, a second wheel arranged at a high position and vertically staggered from the first wheel, and a plurality of reversing wheels arranged between the first wheel and the second wheel, the first wheel, the second wheel Wheels and a plurality of reversing wheels make the chain include vertical uplinks and downlinks. An uplink broken chain protection device is provided on the uplink section, and a downlink broken chain protection device is provided on the downlink section. When the uplink section and / or the downlink section When the chain is broken, the processor will stop the wheelset according to the speed signal, and the uplink broken chain protection device and / or the downlink broken chain protection device will catch the broken chain.

Description

technical field [0001] The present invention relates to conveying machinery, in particular to chain conveyors. The invention also relates to a chain breaking protection method for the chain conveyor. Background technique [0002] The climbing conveyor has the advantages of simple structure, reliable operation, convenient maintenance and other advantages of general belt conveyor, so it is widely used in coal, metallurgy, construction, grain, chemical industry, electric power and other departments. In order to obtain better material receiving and unloading conditions, the driving wheels are usually set at different heights and horizontal positions, and the closed chain is supported by the driving wheels to make a "Z" rotary motion, that is, it has an upper horizontal section , the lower horizontal segment and the vertical segment. The hopper is connected to the chain through the pin shaft, and under the action of the chain on the drive wheel, the hopper can rotate around the...
