[0024] A backwashing cyclone desander includes a desander housing 1, a pad 2, and a stepper motor 3. The pad 2 is fixedly installed on the outer side of the left end of the desander housing 1. The stepper motor 3 is fixedly installed at the bottom end of the pad 2. A shaft 4 is fixedly installed at the end of the main shaft of the stepper motor 3. An active gear 5 is fixedly installed on the outer side of the shaft 4. The teeth on the outer side of the active gear 5 mesh with the grooves on the outer side of the driven gear 6. A connecting ring 7 is fixedly installed on the inner side of the driven gear 6. A discharge shell 8 is fixedly installed inside the connecting ring 7. A hemispherical block 9 is fixedly installed on the inner wall of the discharge shell 8. A ring 10 is installed on the outer side of the discharge shell 8. A sleeve frame 11 is fixedly installed on the outer side of the right end of the desander housing 1. A pad 12 is fixedly installed on the left side below the sleeve frame 11. A retaining ring 13, a lower sleeve ring 14, and an electric telescopic rod device 15 are fixedly installed on the top of the pad 12. A pressure table 16 is fixedly installed on the top of the electric telescopic rod device 15. An upper sleeve ring 17 is fixedly installed on the bottom end of the pressure table 16.

[0025] The top of the discharge shell 8 is connected to the bottom of the sand separator shell 1. Through this arrangement, sand and gravel settle and accumulate in the internal area of ​​the discharge shell 8 at the top of the pressure platform 16.

[0026] The inside of the pad 12 is provided with an annular discharge chute. Through the above-mentioned arrangement, sand and gravel are discharged through the annular discharge chute between the surrounding ring 13 and the upper ring 17.

[0027] The rubber ring fixedly installed on the outer side of the pressure table 16 is in close contact with the inner wall of the material discharge shell 8. Through the above arrangement, the rubber ring fixedly installed on the outer side of the pressure table 16 plays a role in sealing the bottom of the material discharge shell 8.

[0028] The inner wall of the upper collar 17 is slidably connected to the lower collar 14. Through this arrangement, the lower collar 14 serves to limit the vertical sliding of the upper collar 17.

[0029] A rubber ring fixedly installed on the lower inner wall of the desander housing 1 is rotatably connected to the feed shell 8 and the ring 10. Through the above arrangement, the rubber ring fixedly installed on the lower inner wall of the desander housing 1 plays a role in sealing the rotation of the feed shell 8 and the ring 10.

[0030] Working process: This utility model provides a bottom discharge structure for a backwashing cyclone sand separator. The main body of the structure facilitates the anti-clogging and agitation of the sand and gravel accumulated at the bottom of the backwashing cyclone sand separator, thereby improving the discharge efficiency of sand and gravel.

[0031] The stepper motor 3 and electric telescopic rod device 15 installed inside the main structure are controlled by an external PLC controller, and the stepper motor 3 and electric telescopic rod device 15 are electrically connected to an external power source.

[0032] The backwashing cyclone desander is a device used in the oil extraction process to separate oil liquids from sand and gravel. The backwashing cyclone desander mentioned above is existing technology and will not be described in detail here. The treated sand and gravel settle and accumulate in the internal area of ​​the discharge shell 8 at the top of the pressure platform 16.

[0033] The angle between the inner wall of the sand separator shell 1 and the inner wall of the discharge shell 8 and the vertical direction is set at 15-20 degrees. When the sand needs to be discharged, the electric telescopic rod device 15 drives the pressure table 16 and the upper collar 17 to move upward until a discharge gap is formed between the rubber ring fixed on the outer side of the pressure table 16 and the inner wall of the discharge shell 8. The stepper motor 3 starts and drives the shaft 4 and the active gear plate 5 to rotate. The driven gear plate 6, the connecting ring 7, the discharge shell 8, the hemispherical block 9 and the ring 10 are integrated rotating sand discharge components. Through the meshing of the active gear plate 5 and the driven gear plate 6, the integrated rotating sand discharge components are driven to rotate, which prevents the sand from clogging and agitates the discharge, thereby improving the discharge efficiency of the sand.

[0034] After the sand and gravel are discharged, the stepper motor 3 is turned off, and the electric telescopic rod device 15 drives the pressure table 16 and the upper collar 17 to move downward and reset until the inside of the upper collar 17 abuts against the lower collar 14 and is limited. At this time, the rubber ring fixed on the outside of the pressure table 16 is in contact with the inner wall below the discharge shell 8.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
