Multi-channel half-dry sludge switching device and sludge conveying system comprising same

Abstract

The invention provides a multi-channel half-dry sludge switching device and a sludge conveying system comprising the same. The multi-channel half-dry sludge switching device comprises a channel main body and a switching portion; the switching portion is arranged on the channel main body; the channel main body is supported and fixed on an installation base plane through a support; the channel main body comprises a main channel which extends to form a first channel and a second channel; the main channel and the second channel are vertical channels; the first channel is an inclined channel; the switching portion comprises a power cylinder, a rotary shaft and a turning plate; the power cylinder is arranged on the outer wall of the first channel; the power cylinder is connected with the rotary shaft through a connecting rod; the rotary shaft is fixed at the connecting position of the first channel and the second channel; a first end of the turning plate is connected with the rotary shaft; a second end of the turning plate is fixed on the corresponding position of the channel main body. According to the multi-channel half-dry sludge switching device and the sludge conveying system comprising the same, the structure is simple, the feeding and the discharging are smooth, the switching is convenient, and the efficiency of the integral sludge conveying system is improved.

Description

technical field [0001] The invention relates to the field of sludge incineration, in particular to a multi-channel semi-dry sludge switching device and a sludge conveying system including the device. Background technique [0002] With the acceleration of urbanization and the rapid development of industrial production in our country, the discharge of urban industrial wastewater and domestic sewage is increasing, and the sewage will produce sludge after being treated by sewage treatment plants. The "Twelfth Five-Year Plan" pointed out that the moisture content of wet sludge needs to be reduced to 60%, but in reality, 80% of the wet sludge has not been properly treated due to the serious shortage of disposal facilities. Less than 10%. [0003] Drying wet sludge and then incinerating it has become the main process for sludge treatment in developed countries, and it is also the main development direction of sludge treatment and disposal in my country. Incineration operation is a...

The "Twelfth Five-Year Plan" pointed out that the moisture content of wet sludge needs to be reduced to 60%, but in reality, 80% of the wet sludge has not been properly treated due to the serious shortage of disposal facilities. Less than 10%

[0003] Drying wet sludge and then incinerating it has become the main process of sludge treatment in developed countries, and it is also the main development direction of sludge treatment and disposal in my country. Incineration operation is an important link and key technology in the entire sludge disposal system. In the sludge incineration operation, the dry sludge conveying equipment includes screw conveyors, conveyor belts, screw pumps and sludge elevators, etc. The above-mentioned conveying equipment will inevitably fail after long-term operation. Once a problem occurs in one of the components, it will cause The entire system is shut down for maintenance, which affects the normal operation of the project and leads to an increase in costs

Therefore, the specific engineering design usually adopts a two-line process of one use and one standby, and the channel switching is realized through the three-way sludge distributor. However, the current sludge distributor has the defects of inconvenient switching, cumbersome disassembly and maintenance, and difficult maintenance. Moreover, the channel is easy to block and needs to be cleaned frequently, resulting in low working efficiency of the incineration process
