Arch-breaking sliding rack system of feed bin

Abstract

The invention discloses an arch-breaking sliding rack system of a feed bin, which is suitable for a flat-bottom round or flat-bottom square bin body for storing dehydrated sludge with the solid ratio of 70-85 percent or like viscous materials with high concentration. A function of breaking material bridges is achieved through carrying out reciprocation at the bottom of the bin body so that the material is discharged successfully. The arch-breaking sliding rack system mainly comprises a sliding rack framework body, a sliding rack guide rail, a guiding rail positioning block, a sliding frame push rod, a stuff sealing box, a shaft coupler, a piston rod, a hydraulic cylinder and an automatic lubricating device, wherein the arch-breaking sliding rack is driven by using a hydraulic power pack. Through adding the sliding rack guide rail and the guide rail positioning block, the sliding rack runs on a specified rail to reduce the stress and the motion of the sliding rack in other directions, thereby the trip running rail of the sliding rack is fixed, the stress structure of the sliding rack is optimized, the friction contact area is reduced, the abrasion is reduced, the guide rail positioning block is replaced according to the running abrasion condition and the influence on the running and the service life of the sliding rack framework body are prevented due to the positioning abrasion or deviation of the guide rail. With a set of automatic lubricating device, the arch-breaking sliding rack system injects lubricant oil from the stuffing sealing box at the fixed time to the sliding rack so as to reduce the friction coefficient of the sliding rack, decrease the abrasion and prolong the service life of the sliding rack.

Description

technical field [0001] The invention relates to an arch-breaking carriage system of a silo, which is especially suitable for storing dewatered sludge or similar high-concentration viscous materials with a flat-bottomed circular or flat-bottomed square silo body. Background technique [0002] As we all know, dewatered sludge with a solid content of 70% to 85% or similar high-concentration viscous materials have poor fluidity, and bridges are easily generated during the unloading process. Therefore, warehouses for storing such materials The whole body adopts the broken arch carriage to destroy the bridging phenomenon, so that the materials can be discharged smoothly. The arch-breaking carriage is the core component of the storage silo system. At present, the arch-breaking carriages used at home and abroad are directly laid on the bottom of the silo without positioning guide rails and without lubrication. It is necessary to overcome all directions of the carriage. The torque i...

Problems solved by technology

The arch-breaking carriage is the core component of the storage silo system. At present, the arch-breaking carriages used at home and abroad are directly laid on the bottom of the silo without positioning guide rails and without lubrication. It is necessary to overcome all directions of the carriage. The torque is large, which makes the resistance of the carriage during the reciprocating movement very large, the required driving power is large, the energy consumption is high, and the wear and tear of the carriage and the coupling is relatively large, so the strength and thickness of the materials used are high. It leads to high equipment cost and is not conducive to the long-term stable use of the system
