Embodiment Construction

[0013] The garbage collection adopts the point-to-point recovery method. When one of the garbage disposal points needs to collect garbage in a centralized manner, the main control system controls the movement of the valve cylinder, and the cylinder transmission rod moves downward, pushing the joint bearing, the connecting block and the connecting rod to move downward. At this time The connecting rod moving downward pushes the valve plate to move downward to the designated position, at this time, the inflatable sealing ring is not inflated and is not sealed.

[0014] When the garbage disposal point stops recycling, the cylinder transmission rod is pulled upwards, and the cylinder transmission rod drives the joint bearing, connecting block, connecting rod and valve plate to move upward to the designated position, and then the inflatable sealing ring on the valve plate is inflated, and the sealing ring Squeeze tight fit joints after expansion to seal.

[0015] When the valve plat...

Abstract

The invention provides an inflatable sealing valve for pneumatic conveying of a solid waste and household garbage pipeline. The inflatable sealing ring is a hollow inflatable ring body and is manufactured from rubber, wherein the inflatable sealing ring is externally connected with an inflating device; the top end of a valve plate is blade-shaped and can shear garbage which is clamped at the bottom parts between the valve plate and a first valve body and a second valve body. With the adoption of the inflatable sealing valve, the problem of air leakage in the conveying of a garbage recovering pipeline can be effectively solved during the process of pneumatically conveying the garbage through the pipeline, and thus zero leakage is achieved; the problems that the garbage is accumulated at the bottom part of a valve seat and the garbage is clamped between the valve plate and the valve bodies during the conveying of the garbage recovering pipeline can be solved.

Description

technical field [0001] The invention belongs to the field of valve equipment, in particular to an airtight valve for pneumatic pipeline transportation of solid waste and household garbage. Background technique [0002] Most of the existing pipeline pneumatic conveying operation valves are in the form of gate knife valves, which directly cut and seal the pipeline. In actual operation, this method often causes: 1. Serious material accumulation in the valve; 2. Serious leakage, resulting in a large loss of fan power consumption. In this case, in order to ensure the efficiency and stability of the recycling system, it is urgent to propose solutions to the above two problems. Contents of the invention [0003] The invention provides an airtight valve for pneumatic pipeline transportation of solid waste and domestic garbage, mainly by installing a sealing valve on a certain part of the pipeline pneumatically conveying, improving the sealing valve so that there is no leakage and...
