Silt collection device

Abstract

The invention belongs to a kind of installment which is used to separate and collect the precipitation solid particle from the liquid, Specially involves the collecting sink granulated substance installment in the sewage treatment.The invention discloses realized like this, it includes the driving car moves along the aeration sand collector, the driving car has the funnel uses to store the granulated substance, on the driving it establishes the runner, lower part is established with the runner, the upper runner and the under runner transmit through the link chain,the is a dig funnel on the chain link,the upper runner has a dive installment on it, Therefore it will be able directly dig out the sink granulated substance from the lower pond, the water content will be extremely low, work 30minutes every day will to be possible to complete the centrifugal pump 24hours work loads, therefore greatly enhances the working efficiency, reduces the equipment movement cost; Compares with the existed technology, the equipment attrition is slight,the energy consumption is few,the cost maintains to be low.Moreover,the moisture content of the granulated substance duged out is very low, did not need to enter the granulated substance water separator to separate, simplifies the craft, saves the equipment, saves the energy.

Description

technical field

[0001] The invention belongs to a device for separating and collecting precipitated solid particles from liquid, in particular to a device for collecting sand in sewage treatment. Background technique

[0002] In sewage treatment technology, aeration grit settling or other methods are often used to settle the sand particles heavier than water, sink them into the grit chamber, and then use centrifugal pump suction to suck out and discharge them from the grit chamber. The Chinese invention patent No. 85108394 discloses a grit collection device for sewage treatment equipment, which includes a crane that can move along the aerated grit chamber, and a centrifugal pump is suspended on the crane, and the centrifugal pump can submerge into the sand and drain the bottom of the tank. The grit and water are pumped out, and transported to the storage hopper on the crane through the pipeline, and then flow from the storage hopper to the san...
