Description

Technical Field

[0001] This utility model relates to the field of proppant production technology, specifically to a powder classifier feeding mechanism for proppant production. Background Technology

[0002] Quartz sand or bauxite are the main raw materials for the production of proppant. In the process of proppant production, the powder classification process ensures the uniformity of particle size and product performance of the proppant raw materials by accurately classifying the powder materials. The powder classifier is a commonly used powder classification device. The powder classifier uses a high-speed rotating classifying turbine to generate centrifugal force and airflow to separate materials of different particle sizes.

[0003] The more dispersed the raw materials used to produce proppant are in the air classifier, the better the air classification effect of the air classifier on the raw materials. However, the raw materials may clump before entering the air classifier. In order to ensure the dispersion of the raw materials, the authorized announcement number CN213591116U "A V-classifier feeding device" mentions a feeding device that breaks up the raw materials by impacting the steel bars. However, this device relies solely on the gravity of the falling material and the impact of the steel bars, which makes it difficult to guarantee the dispersing effect. Moreover, when the clumped raw materials pass between the stationary steel bars, they are prone to jamming, causing material blockage. Utility Model Content

[0004] This invention addresses the problems of poor powder selection effect when agglomerated raw materials used in proppant production enter the powder classifier and poor dispersion effect when existing devices are used to disperse agglomerated raw materials. It provides a powder classifier feeding mechanism for proppant production that can break up agglomerated raw materials from multiple angles, thereby improving the powder selection effect of the powder classifier.

[0005] To solve the above problems, the technical solution of this utility model is: A powder classifier feeding mechanism for proppant production includes a cylindrical body with an open top and a feeding pipe connected to the bottom of the cylindrical body; it also includes a support pipe, a vertical rod, and an S-shaped rod. The support pipe is located inside the lower part of the cylindrical body and is fixedly connected to the inner wall of the cylindrical body at both ends. The upper middle part of the support pipe is rotatably connected to the vertical cylinder, and the top of the vertical cylinder is rotatably connected to the vertical rod. A driving component is provided inside the support pipe to drive the vertical cylinder and the vertical rod to rotate in opposite directions. Multiple S-shaped rods are arranged in a ring array on the outer side of the vertical rod. Each S-shaped rod includes multiple n-shaped rods and connecting rods. The multiple n-shaped rods are spaced apart from top to bottom. The inner end of the lower horizontal bar of the upper n-shaped rod is connected to the inner end of the upper horizontal bar of the adjacent lower n-shaped rod via a connecting rod. The lower end of the S-shaped rod is fixedly connected to the outer wall of the vertical cylinder, and the upper end is rotatably connected to the vertical rod. Each n-shaped rod on the S-shaped rod is provided with a stirring rod whose inner end is fixedly connected to the vertical rod.

[0006] Furthermore, the vertical cylinder is a cylinder with an open lower end. The outer wall of the vertical cylinder is rotatably connected to the upper part of the peripheral wall of the bearing pipe, and the lower end extends into the upper part of the bearing pipe. The upright is rotatably connected to the top plate of the vertical cylinder, and the lower end is located inside the vertical cylinder. The upper end of the vertical cylinder is connected to a guide cylinder that is sleeved outside the upright. The guide cylinder is a hollow frustum with open ends.

[0007] Furthermore, the driving component includes a rotating rod and a bevel gear one. The rotating rod is coaxially disposed inside the bearing tube. One end of the rotating rod is rotatably connected to the circumferential wall of the cylinder, and the other end is movably inserted through the circumferential wall of the cylinder and driven to rotate by a motor. The lower ends of the vertical cylinder and the vertical rod are both higher than the rotating rod. The lower part of the outer wall of the vertical cylinder is fitted with a bevel gear one located inside the bearing tube. The rotating rod is fitted with and fixed with bevel gear two and bevel gear three with their small ends facing each other. Bevel gear two meshes with the left end of bevel gear one. The lower end of the vertical rod is fitted with and fixed with bevel gear four. The upper end of bevel gear three extends into the vertical cylinder and meshes with the right end of bevel gear four.

[0008] Furthermore, the upper end of the S-shaped rod is the inner end of the uppermost horizontal bar of the n-shaped rod, and the lower end is the inner end of the lower horizontal bar of the n-shaped rod. There is a gap between the outer end of each n-shaped rod on the S-shaped rod and the inner wall of the cylinder.

[0009] Furthermore, the upper ends of the multiple S-shaped rods are connected to a connecting ring 1 that is sleeved on the outside of the upright, and the inner ring of the connecting ring 1 is rotatably connected to the upright.

[0010] Furthermore, the upper end of the upright is fitted with a second connecting ring. The inner ring of the second connecting ring is rotatably connected to the outer wall of the upright, and the outer ring of the second connecting ring is connected to the inner wall of the cylinder via multiple connecting rods in a circular array.

[0011] The beneficial effects of this utility model through the above technical solution are as follows: This invention uses a drive unit to drive the vertical cylinder and the vertical rod to move in opposite directions, and multiple S-shaped rods and multiple stirring rods to move in opposite directions. As the raw material used to produce the proppant falls into the cylinder, it can be repeatedly and multi-angledly impacted by the S-shaped rods and stirring rods. The S-shaped rods and stirring rods can break up the agglomerated raw material at different heights, thereby dispersing the agglomerated proppant raw material, reducing the amount of agglomerated raw material entering the classifier, and improving the classifier effect.

[0012] Furthermore, because multiple S-shaped rods and multiple stirring rods are in a rotating state, it can prevent the agglomerated raw materials from clogging the cylinder. Attached Figure Description

The motor 12 is fixed to the outer wall of the cylinder 1, and the output end of the motor 12 is connected to the rotating rod 11 and movably inserted through one end of the cylinder 1. The lower ends of the vertical cylinder 6 and the vertical rod 4 are both higher than the rotating rod 11. The lower part of the outer wall of the vertical cylinder 6 is fitted with a bevel gear 13 located inside the bearing tube. The rotating rod 11 is fitted with two bevel gears 14 and 15 with their small ends facing each other. The bevel gear 14 meshes with the left end of the bevel gear 13. The lower end of the vertical rod 4 is fitted with a bevel gear 16. The upper end of the bevel gear 15 extends into the vertical cylinder and meshes with the right end of the bevel gear 16.

[0018] The upper end of the S-shaped rod 5 is the inner end of the upper horizontal bar of the uppermost n-shaped rod 5a, and the lower end is the inner end of the lower horizontal bar of the lowermost n-shaped rod 5a.

Figure 1 (from a top-down perspective), the upright 4 drives multiple stirring rods 7 to rotate counterclockwise with the bevel gear 4; After the raw materials for producing the proppant are fed into the cylinder 1 through the upper opening, the agglomerated raw materials are impacted by multiple clockwise rotating S-shaped rods 5 or counterclockwise rotating stirring rods 7 as they move downwards within the cylinder 1. Since the S-shaped rods 5 and stirring rods 7 move in opposite directions, the probability of the agglomerated raw materials being impacted is increased, thereby improving the dispersion effect of the agglomerated material. The S-shaped rods 5 are arranged in layers by multiple n-shaped rods 5a, covering different falling heights. The stirring rods 7 are located within each n-shaped rod 5a. The agglomerated raw materials are repeatedly impacted during the falling process, forming multi-stage dispersal, which further improves the dispersion effect. At the same time, since the S-shaped rods 5 and stirring rods 7 are in motion, the blockage of agglomerated raw materials within the cylinder 1 can be avoided. The raw materials dispersed by the impact of the S-shaped rod 5 and the stirring rod 7 enter the classifier through the feed pipe 2.
