DETAILED DESCRIPTION

[0014] In order to more clearly illustrate the technical scheme of the embodiments of the present application, the following will briefly introduce the drawings needed to be used in the embodiments. Obviously, the drawings described in the following are some embodiments of the present application, and for those skilled in the art, other drawings can also be obtained according to these drawings without creative labor.

[0015] Please refer to Figs. 1 to 3The utility model discloses a kind of quartz sand washing mud sand treatment devices 10 including mud mortar pipeline 20, mortar centrifugal separation mechanism 30, mortar sedimentation separation mechanism 40, quartz sand sorting mechanism 50, the mud mortar pipeline 20 one end is connected with the feed end of mortar centrifugal separation mechanism 30, mortar centrifugal separation mechanism 30 is used for heavy quartz sand and mud separation, the top of mortar centrifugal separation mechanism 30 is connected with the upper end of mortar sedimentation separation mechanism 40, and mortar sedimentation separation mechanism 40 is used for light quartz sand and mud separation, the bottom of mortar centrifugal separation mechanism 30 is connected with quartz sand sorting mechanism 50, and quartz sand sorting mechanism 50 is used for the separation of different mesh of quartz sand.

[0016] The mud mortar pipeline 20 of the utility model is used to collect different mud mortar produced in quartz sand screening link. Because the purity and particle size of quartz sand in quartz sand raw material cannot meet the requirements, it needs to be screened in multiple stages. Each stage of screening will produce mud mortar. Mud mortar pipeline 20 needs to collect and process these mud mortars.

[0017] The mortar centrifugal separation mechanism 30 is used for separating heavy quartz sand in mud mortar. Heavy quartz sand is generally quartz sand with large particle size, which is easy to separate from light components in mud mortar under the action of centrifugal force.

[0018] In a preferred embodiment, the mortar centrifugal separation mechanism 30 includes a centrifugal separation cylinder 301, a mud pipeline 302 and a heavy quartz sand pipeline 303. The upper end of the centrifugal separation cylinder 301 is cylindrical, the lower end of the centrifugal separation cylinder 301 is conical, the feed inlet of the centrifugal separation cylinder 301 is located at the upper end of the centrifugal separation cylinder 301 and is tangent to the side wall of the centrifugal separation cylinder 301, one end of the mud pipeline 302 is communicated with the shaft center at the top of the centrifugal separation cylinder 301, the other end of the mud pipeline 302 is connected with the upper end of the mortar sedimentation separation mechanism 40, the upper end of the heavy quartz sand pipeline 303 is communicated with the bottom of the centrifugal separation cylinder 301, and the lower end of the heavy quartz sand pipeline 303 is located above the quartz sand sorting mechanism 50.

[0019] The feed inlet of the centrifugal separation cylinder 301 and the mud mortar pipeline 20 can be connected by flange, which is convenient for later maintenance and replacement. It should be understood that the incoming material in the mud mortar pipeline 20 is lifted by a water pump, and the mud mortar has a certain kinetic energy, so that centrifugal separation can be carried out. The light mud mortar separated from heavy quartz sand enters the mortar sedimentation separation mechanism 40 along the mud pipeline 302 from the top of the centrifugal separation cylinder 301.

[0020] In a preferred embodiment, the mortar sedimentation separation mechanism 40 comprises a mortar sedimentation tank 401, a light quartz sand pipeline 402, and a slurry pipeline 403, the upper end of the mortar sedimentation tank 401 is open, the upper end of the mortar sedimentation tank 401 is connected with the slurry pipeline 302, the lower end of the side wall of the mortar sedimentation tank 401 is connected with the light quartz sand pipeline 402, and the upper end of the side wall of the mortar sedimentation tank 401 is connected with the slurry pipeline 403.

[0021] The mortar sedimentation separation mechanism 40 of the utility model separates the light quartz sand and the slurry by natural sedimentation. The light slurry entering the mortar sedimentation tank 401 mainly contains clay and small-diameter quartz sand. After entering the mortar sedimentation tank 401, the speed of the light slurry is also small, while the light quartz sand has a larger density than the clay and is more likely to settle, and the settled light quartz sand is discharged from the light quartz sand pipeline 402 along with the water body for the next process treatment, while the slurry mixed with the clay is discharged from the slurry pipeline 403 for the next process treatment.

[0022] The quartz sand separation mechanism 50 of the utility model is used for separating heavy quartz sand with different diameters, which is the same as the device used in the quartz sand screening stage. It can be a vibrating screen or a cylindrical screen.

[0023] In a preferred embodiment, the quartz sand separation mechanism 50 is a vibrating screen.

[0024] Generally, the mortar flow from the slurry pipeline 20 is relatively large. If a centrifugal separation cylinder 301 with a larger diameter is used, although the flow treated is larger, the separation effect of the heavy quartz sand will be poor. There will be more heavy quartz sand mixed in the light slurry.

[0025] Therefore, in a preferred embodiment, the slurry pipeline 20 is provided with two discharge ports, and correspondingly, the mortar centrifugal separation mechanism 30 comprises two centrifugal separation cylinders 301.

[0026] By providing two centrifugal separation cylinders 301, the treatment of the incoming material can be basically realized, and the separation effect is good. Of course, if the flow is larger, more than three centrifugal separation cylinders 301 can also be used for treatment.

[0027] The above only discloses the preferred embodiment of the utility model, and of course cannot limit the scope of the utility model, and the person skilled in the art can understand that all or part of the processes of the above embodiment can be implemented, and equivalent changes made according to the utility model claims still belong to the scope covered by the utility model.
