Problems solved by technology
The advantage of this method is that it has the effect of diluting the sediment mixture; the disadvantage is that for equipment with a large amount of sediment such as primary water treatment equipment, the ability to discharge sediment only by gravity and water flow is low, which cannot meet continuous operations.

The invention provides a spiral water flow sand removing device. The spiral water flow sand removing device comprises a sand discharging pipe, an outer sleeve and a water inlet pipe, wherein the upper end of the outer sleeve is connected with the outer wall of the sand discharging pipe in a sealing way; a water discharging cavity is formed between the sand discharging pipe and the outer sleeve; spiral blades are fixedly arranged in the water discharging cavity from top to bottom; the right end of the water inlet pipe is fixedly connected with the upper part of the outer wall of the outer sleeve; the water inlet pipe is communicated with the water discharging cavity. According to the spiral water flow sand removing device provided by the invention, the structure is simple, and the use and the maintenance are convenient; the whole structure is convenient to disassemble and assemble, and the spiral water flow sand removing device can be directly put into a device from a manhole in a tank body; compared with a common sand discharging pipeline depending on the gravity action, the spiral water flow sand removing device has the advantages that the sand discharging capacity is stronger, and the requirements of continuous operation can be met; in addition, the functions of diluting and pumping silt in a tank can be simultaneously achieved through eddy water.
Description
technical field [0001] The invention belongs to the field of closed tank cleaning, and in particular relates to a sand removal device. Background technique [0002] In the prior art, the way to remove the silt at the bottom of the tank is to spray the bottom of the tank with a certain pressure cleaning water to dilute the sediment in the tank, and the sewage is discharged out of the tank through the discharge port through gravity. The advantage of this method is that it has the effect of diluting the sediment mixture; the disadvantage is that for equipment with a large amount of sediment such as primary water treatment equipment, the ability to discharge sediment only by gravity and water flow is low, which cannot meet continuous operations. Contents of the invention [0003] In view of this, the present invention aims to propose a vortex sand removal device to improve the ability to remove sand from the bottom of the tank and to meet continuous operations. [0004] In or...
