Device for avoiding arching of materials in stock bin by using sliding frame

Abstract

The invention discloses a device for avoiding arching of materials in a stock bin by using a sliding frame. The device comprises a guide rail (1), the slide frame, a power system (10), and a stock bin body (4), wherein the guide rail (1) is arranged on two sides of the bottom of the stock bin body (4); the slide frame consists of a slide frame body (7) and a slide frame rod; a roller cover (6) and a roller (3) are arranged on the guide rail (1); the roller cover (6) and the roller (3) are simultaneously connected with the slide frame; the roller (3) is arranged in the roller cover (6); and the slide frame rod comprises rectangular inner slide frame rods (9.1) and sawtooth-shaped outer slide frame rods (9.2) which are centrosymmetric about the slide frame. By the device, rolling friction is generated between the slide frame and the guide rail, so that the friction force between the slide frame and the guide rail can be greatly reduced, driving force and power consumption of the power system are correspondingly reduced, and wear of the slide frame and the guide rail is reduced.

Description

Technical field: [0001] The invention relates to an arch breaking device for a silo, in particular to a device for breaking an arch of a material in a silo using a sliding frame, especially suitable for a flat-bottomed silo body of dewatered sludge or high-viscosity viscous material. Background technique: [0002] At present, during the storage of materials, relying on the gravity of the materials themselves to make the materials flow to the outlet of the silo, it is easy to cause arching, sticking, and blockage of the materials in the silo, especially when the material contains a large amount of water, mud or the material itself When the viscosity is high, the adhesion of the material is stronger, and the silo blockage of different degrees is more likely to occur. Once the silo is blocked, it will not only affect the full play of the silo, but also seriously damage the continuity of the production process. Therefore, how to remove arching, clogging and sticking of silos in...

AI Technical Summary

Problems solved by technology

This method has the following problems: (1) a large amount of material is pressed on the carriage, and the carriage is under great pressure, and there is a large sliding friction of the friction system between the carriage and the guide rail, which requires a large hydraulic pressure to drive carriage work

It also requires a larger hydraulic station and power consumption to provide hydraulic driving force; (2) Due to the large friction force, the wear between the carriage and the guide rail is also relatively large, and irregular maintenance of the carriage and guide rail is required; (3) ) When the hydraulic drive system is driven by a single cylinder, the force on one side of the carriage is unbalanced, and the synchronization accuracy is low when driven by two cylinders, and there is a large position error after a long running time
