Fine sand sorting machine

Abstract

The invention provides a fine sand sorting machine. The machine comprises a first spiral conveyor, a second spiral conveyor, a sand and water separation box body and a sand discharge mechanism; a seriflux inlet is formed in the top portion of one end of the sand and water separation box body, a water retaining plate is arranged in the sand and water separation box body, and the water retaining plate is located under the seriflux inlet, so that seriflux which enters from the seriflux inlet can only impact on the water retaining plate; a water outlet which is communicated with the bottom of a clear water cavity is formed in the sand and water separation box body, the first spiral conveyor and the second spiral conveyor which are located on the bottom of a muddy water cavity are arranged in the sand and water separation box body, and a flexible pipe which is located below the seriflux inlet is arranged in the sand and water separation box body; the first spiral conveyor and the second spiral conveyor are all used for transporting fine sand of the bottom of the muddy water cavity to the flexible pipe, and the flexible pipe transports the fine sand to the sand discharge mechanism which is located below the sand and water separation box body. The fine sand sorting machine has the advantages that through third rotary-type spiral transport tubes, sand discharge is more thorough, and the electricity usage amount is reduced, the energy is saved, and the cost is lowered; the survival life of the device is prolonged by a slag discharge device.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a fine sand separator. Background technique [0002] In the field of environmental protection, it is sometimes necessary to separate the fine sand from water, collect the fine sand, and then collect the sewage, and the fine sand separator comes in handy. The sand discharge mechanism is a part of the fine sand separator, which is used to lift the fine sand and separate it from water, so it plays a vital role. [0003] In the prior art, there are currently the following deficiencies: due to the difference in the thickness of the slurry entering the slurry separation device (the previous process of the sand discharge mechanism), the sand discharge mechanism of the fine sand separator is usually fixed beside the fine sand separator. , The sand discharge mechanism includes a sand discharge pipe with an inclined setting. Because the sand discharge pipe is fixed, it is impossi...
