Detailed Description

Because present sand discharging device is not good to the silt particle treatment effect in the sewage, follow-up needs the manual work to carry out periodic cleaning to sand discharging device, and is inefficient, and people of being not convenient for use for a long time, therefore we have designed a neotype sand discharging equipment on prior art defect's basis, can effectively be used for sewage treatment, and is efficient, and the people of being convenient for use.

In order to make the technical solution more clear to those skilled in the art, the technical solution of the present invention will be described in detail below with reference to fig. 1-2: a sand discharge device for sewage treatment comprises a sedimentation tank 1 with an opening at the upper end, wherein inclined planes 2 which are inclined inwards are symmetrically arranged on the front side and the rear side of the interior of the sedimentation tank 1, a sand collecting groove 3 is arranged at one end of the interior of the sedimentation tank 1, an equipment installation groove 4 is arranged at the bottom of the interior of the sedimentation tank 1, a sand conveying groove 5 is fixedly arranged in the equipment installation groove 4, and a spiral sand collecting mechanism is arranged in the sand conveying groove 5; the during operation, at first sewage gets into from the entrance of sedimentation tank 1, and the work of spiral collection sand mechanism can be discharged the silt particle in the sand conveyer trough 5 to collection sand tank 3 after that, at this in-process, because the inclined plane 2 of the both sides for the slope of sedimentation tank 1, consequently fall to the silt particle on the sedimentation tank 1 also can fall to the sand conveyer trough 5 through inclined plane 2 in, and the sand setting collection efficiency is high, and the people of being convenient for use.

Wherein, in order to adjust the mounting height of sand conveyer trough 5 better, the outside bilateral symmetry of sand conveyer trough 5 is equipped with a plurality of landing legs 7 that play the supporting role, the one end of landing leg 7 passes through bolted connection with

sand conveyer trough

5, 4 fixed connection of bottom equipment mounting groove in anchor bolt and the sedimentation tank 1 are passed through to the other end of landing leg 7, and wherein the height of landing leg 7 can set up as required, then pour through the secondary and make

sand conveyer trough

5 and 4 zonulae occludens of equipment mounting groove, make sand conveyer trough 5 meet with inclined plane 2 simultaneously, make things convenient for the sand setting to fall to sand conveyer trough 5 better in, make things convenient for the sand setting to fall to sand conveyer trough 5 better.

Wherein, for better collecting the sand setting, the periphery of sand collecting groove 3 is the shape of inside slope for the sand setting can fall better to sand collecting groove 3 in.

Elaborating in detail the structure of the spiral sand collecting mechanism, the spiral sand collecting mechanism comprises a motor 61, a spiral shaft 62 connected with the motor 61, and a first spiral blade 63 arranged on the spiral shaft 62, the motor 61 is fixedly mounted on one side of the sedimentation tank 1 close to the sand collecting tank 3, the first spiral blade 63 is coated in the sand conveying tank 5, wherein a second spiral blade 8 opposite to the first spiral blade 63 is arranged on one side of the spiral shaft 62 close to the sand collecting tank 3, and the protection effect on the motor 61 can be achieved to prevent sand from damaging the motor 61 after entering the motor 61.

In order to stop the metal friction between the first spiral blade 63 in the sand conveying groove 5 and the sand conveying groove 5, the service life of the equipment is greatly prolonged, a wear-resistant liner is further arranged between the first spiral blade 63 and the sand conveying groove 5, the wear-resistant liner is fixedly installed in the sand conveying groove 5, after the sand conveying groove is used for a certain time, only the wear-resistant liner needs to be replaced, and the later maintenance cost is effectively reduced.

In order to make the length of the screw shaft 62 not limited by the length of the raw material, the screw shaft 62 is assembled by segments and can be applied to the sand discharge equipment with various length requirements.

The following description of the system illustrates the overall working principle of the present invention: sewage enters a sand conveying groove 5 in the sedimentation tank 1 from an inlet at one end, part of sand in the sewage enters the sand conveying groove 5 through natural sedimentation, because the interior of the sedimentation tank 1 is obliquely arranged, the silt left on the side surface of the sedimentation tank 1 can also fall into the sand conveying groove 5 through the inclined surface 2, in the process, some silt falls into the silt collecting tank 3, then the control motor 61 is operated, the screw shaft 62 is rotated by the control motor 61, at this time, the first screw blade 63 on the screw shaft 62 can discharge the silt at the bottom of the sand conveying tank 5 into the silt collecting tank 3, in the process, the mud and sand are prevented from entering and damaging the motor, the second spiral blade 8 which is opposite to the first spiral blade 63 is arranged on the spiral shaft 62, and the second spiral blade 8 can reversely discharge the mud and sand at the inlet of the first spiral blade 63 into the sand collecting groove 3 when the first spiral blade 63 works.
