An object of the utility model is to the above-mentioned problem that prior art exists, provide an energy-saving desander, change traditional multistage desanding into single section, it is many to have solved traditional multistage desander equipment, and the system is complicated, and the running cost is high, and spare parts are many, the big scheduling problem of area.
The purpose of the utility model can be realized by the following technical proposal:
the utility model provides an energy-saving desander, including advancing the thick liquid pipe, still include the upper portion barrel, upper portion barrel top is provided with out the thick liquid pipe, advance thick liquid pipe and upper portion barrel intercommunication, the thick liquid direction of advancing that advances the thick liquid pipe is the circumference tangential direction of upper portion barrel, upper portion barrel bottom opening passes through the flange and is connected with the top opening of middle part back taper, the bottom opening of middle part back taper passes through the flange and is connected with the top opening of lower part back taper, the bottom opening of lower part back taper passes through the flange and is connected with last pneumatic switch valve one end, it is connected with festival thick liquid ware one end through the flange to go up the pneumatic switch valve other end, the festival thick liquid ware other end passes through the flange and is connected with lower pneumatic switch valve one end, the pneumatic switch valve other end passes through the flange and arranges the slag union coupling down, festival.
The slurry saver is provided with a sight glass.
The pulp saver is cylindrical, and the water inlet direction of the elutriation water pipe is the circumferential tangential direction of the pulp saver.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the energy consumption is low;
2. the occupied area is small;
3. the number of the mounting components is small, and the mounting and dismounting are convenient;
4. the slurry separation effect is good;
6. the elutriation and deslagging can be flexibly adjusted.

Detailed Description
To facilitate understanding and practice of the invention by those of ordinary skill in the art, the following detailed description of the invention is provided in connection with the examples, and it is to be understood that the examples described herein are for purposes of illustration and explanation only and are not intended to limit the invention.
As shown in fig. 1, an energy-saving desander, including advancing thick liquid pipe 1, still include upper portion barrel 3, 3 tops of upper portion barrel are provided with out thick liquid pipe 2, it communicates with upper portion barrel 3 to advance thick liquid pipe 1, the thick liquid direction of advancing thick liquid pipe 1 is the circumference tangential direction of upper portion barrel 3, the top opening that upper portion barrel 3 bottom opening passes through flange and middle part back taper 4 is connected, the bottom opening that middle part back taper 4 passes through flange and the top opening of lower part back taper 5 is connected, the bottom opening that lower part back taper 5 passes through flange and is connected with last pneumatic switch valve 6 one end, it is connected with festival thick liquid ware 8 one end through flange and to go up the pneumatic switch valve 6 other end, the 8 other ends of festival thick liquid ware passes through flange and is connected with lower pneumatic switch valve 7 one end, the 7 other ends of lower pneumatic switch valve passes through flange and is connected with row sediment pipe 11, festival thick liquid ware 8 and elutriat. The slurry saver 8 is provided with a sight glass 9. The pulp saver 8 is cylindrical, and the water inlet direction of the elutriation water pipe 10 is the circumferential tangential direction of the pulp saver 8.
The utility model discloses a remove heavy impurity process as follows:
under the operating condition, the slurry keeps certain pressure and enters from the slurry inlet pipe 1, passes through the upper barrel 3, the middle inverted cone 4 and the lower inverted cone 5 in sequence, the slurry is under the action of centrifugal force, heavy impurities are separated from the slurry outwards, and good slurry is gathered inwards and upwards and discharged from the slurry outlet pipe 2. In the elutriation state, the upper pneumatic switch valve 6 is opened, heavy impurities are gathered in the pulp saver 8 through the upper pneumatic switch valve 6, elutriation water is continuously introduced into the elutriation water pipe 10, the heavy impurities are continuously elutriated in the pulp saver 8, qualified pulp is elutriated again and upwards enters the pulp outlet pipe 2, and the lower pneumatic switch valve 7 is in a closed state in the elutriation process. In the state of slag discharge, the upper pneumatic switch valve 6 is closed, the lower pneumatic switch valve 7 is opened, heavy impurities are discharged through the slag discharge pipe 11, the elutriation water pipe 10 is continuously introduced with elutriation water, and the pulp saver 8 is cleaned.
