Automatic telescopic type sludge storage bin sealing cover plate device

Abstract

The invention discloses an automatic telescopic type sludge storage bin sealing cover plate device. The automatic telescopic type sludge storage bin sealing cover plate device comprises a sludge storage bin, a hydraulic transmission mechanism arranged on the upper part of the sludge storage bin and a telescopic cover plate mechanism, wherein the telescopic cover plate mechanism comprises travelling wheels, scissors forks, matched scissors forks, a steel cover plate, a matched steel cover plate, central shafts, upper central shafts and connecting shaft pins, the scissors forks and the matched scissors forks separately pass through the upper central shafts, the central shafts and the connecting pin rolls and then are connected to form a scissors fork structure; the steel cover plate and thematched steel cover plate are separately in matched connection to the scissors forks and the matched scissors forks; wheel rails are arranged on positions, along surfaces, of bin portions on the two side walls of the sludge storage bin; the travelling wheels are arranged among the scissors forks, the matched scissors forks, the steel cover plate and the matched steel cover plate; the hydraulic transmission mechanism is arranged at one end of the sludge storage bin; and after the hydraulic transmission mechanism is started, the scissors forks at the front end are stressed to move, so that the travelling wheels roll along the wheel rails, and therefore, the whole telescopic cover plate mechanism is driven to accomplish shrinkage and expansion motion.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment equipment, in particular to an automatic telescopic sludge storage bin sealing cover device. Background technique [0002] Sludge is the product of sewage treatment. It is a heterogeneous body with extremely complex components, composed of organic debris, bacterial cells, inorganic particles, colloids, etc. Due to the high content of organic matter in the sludge, it is very easy to rot and smell. At the same time, some sludge also contains dangerous substances such as heavy metals and pathogenic microorganisms. At present, the various processes of sludge disposal will involve the problem of sludge storage. Avoiding direct contact with people during the process, while maintaining the tightness of the storage process and other issues need to be solved urgently. Therefore, it is very important to use an automatic retractable cover device with good sealing performance for the sludge storage b...

Problems solved by technology

[0004] The object of the present invention is to provide an automatic telescopic sludge storage bin sealing cover device to solve the problem of sealing the underground mud bin in the prior art, which directly uses the electro-hydraulic push rod as the power actuator to pull the steel cover to the sludge. However, this kind of cover plate has problems such as poor sealing performance, occupying too many positions in space, limited sealing area, and the storage bin cannot be too large. Under the large situation, the technical problem that this form of cover plate is not applicable; Many technical effects that the preferred technical solution in the many technical solutions provided by the present invention can produce are set forth in detail below
