Description

Technical Field

[0001] This utility model relates to the field of quartz sand production technology, specifically to a quartz sand raw material stabilizing bin. Background Technology

[0002] In hydraulic fracturing operations for oil and gas extraction, quartz sand is used as a proppant and is pumped into rock fractures under high pressure to prevent the fractures from closing, thus allowing oil or natural gas to flow out smoothly. During the production of quartz sand, it needs to be crushed to obtain quartz sand particles of a certain size. The double roll crusher is a commonly used crushing equipment. The two opposing rollers on the double roll crusher squeeze and grind the material to break it. It is suitable for medium and fine crushing of quartz sand. The quartz sand raw material to be crushed enters the double roll crusher through a flow stabilizing chamber, which ensures continuous, stable and uniform feeding of the double roll crusher.

[0003] When the flow stabilizing bin is in use, there are problems as mentioned in the authorization announcement number CN222624681U "A Flow Stabilizing Bin for a Roller Press". Because the flow stabilizing bin is generally a square pyramid structure with gradually decreasing internal aperture, when the material is discharged through the flow stabilizing bin, it is easy to form an arching and bridging phenomenon, which can easily cause material blockage and result in poor feeding of the roller crusher. Utility Model Content

[0004] This invention addresses the problem of quartz sand raw materials easily forming brittle hoppers within the feed chamber when fed to a roller crusher. It provides a quartz sand raw material feed chamber that prevents the raw materials from interacting and forming brittle hoppers, thus improving the smoothness of material feeding.

[0005] To solve the above problems, the technical solution of this utility model is: A quartz sand raw material stabilization silo includes an upper silo and a lower silo; it also includes a vertical plate and a disturbance component. The vertical plate is located inside the lower part of the upper silo and is fixedly connected to the left and right side plates of the upper silo at both ends. The disturbance component includes a shell and a column. The shell is driven by an electric telescopic rod and slides left and right around the vertical plate. A rotating cylinder is rotatably connected at intervals on the bottom plate of the shell. The lower end of the rotating cylinder extends into the lower silo. Multiple horizontal disturbance rods are provided on the outer wall of the rotating cylinder. The column slides up and down inside the rotating cylinder. A drive column is provided on the lower part of the peripheral wall of the column. The drive column extends into a spiral groove opened in the inner wall of the rotating cylinder. A U-shaped groove is recessed downward on the top surface of the column. The upper part of the U-shaped groove is movably locked outside the vertical plate. The vertical plate has an inclined hole corresponding to the U-shaped groove, with the left side higher than the right side. A drive rod is slidably installed in the inclined hole. The two ends of the drive rod extend out of the inclined hole and connect to the column on the front and rear sides of the inclined hole, respectively.

[0006] Furthermore, the left and right closed ends of the housing are provided with through holes that fit around the upright plate, and sealing rings that slide in contact with the outer side of the upright plate are fixed in the through holes; the outer top surface of the housing is an arc-shaped surface with the protrusion facing upward.

[0007] Furthermore, the rotating cylinder includes a cylinder body one and a cylinder body two, which are alternately arranged in the length direction of the shell. A cylinder body two is provided between every two adjacent cylinder bodies one. The spiral groove includes a groove body one and a groove body two with opposite rotation directions. The groove body one is opened in the cylinder body one, and the groove body two is opened in the cylinder body two.

[0008] Furthermore, the disturbance rod located on the outer wall of the first cylinder is a rod body one. Multiple sets of rod bodies one are arranged from top to bottom on the first cylinder. Multiple rod bodies one in the same set are arranged in a ring array along the outer wall of the first cylinder. Between two adjacent sets of rod bodies one, on one side of the outer wall of the second cylinder, a set of rod bodies two is arranged. Multiple rod bodies two in the same set are arranged in a ring array along the outer wall of the second cylinder.

[0009] Furthermore, each of the drive rods is circumferentially slidably fitted with a sleeve, which is located in the U-shaped groove where the drive rod is located, and the outer wall of the sleeve makes rolling contact with the side of the inclined hole where the drive rod is located.

[0010] Furthermore, the distance between the upper and lower ends of the U-shaped groove is greater than the distance between the upper and lower ends of the oblique hole; when the housing moves to the left or right, each oblique hole is located inside the housing.

[0011] The beneficial effects of this utility model through the above technical solution are as follows: When the shell of this invention moves to the left or right, cylinder one and cylinder two on the shell can laterally disturb the quartz sand material. Moreover, guided by the oblique holes on the vertical plate, cylinder one and cylinder two will rotate in opposite directions. Cylinder one drives rod one to disturb the quartz sand material, and cylinder two drives rod two to disturb the quartz sand material. The rotation direction of rod one is opposite to that of rod two, which can disturb the quartz sand material from multiple angles. Therefore, this invention can prevent the quartz sand material from forming a balanced structure in the stabilizing chamber, so that the material can be fed smoothly. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-5 As shown, a quartz sand raw material stabilization silo includes an upper silo body 1 and a lower silo body 2 connected to the lower end of the upper silo body 1. The upper silo body 1 is a hollow cuboid with openings at both the top and bottom. The lower silo body 2 is a hollow frustum with a larger top and smaller bottom and openings at both the top and bottom. It also includes a vertical plate 3 and a disturbance component. The vertical plate 3 is a rectangular plate located inside the lower part of the upper silo body 1, and its two ends are fixedly connected to the left and right side plates of the upper silo body 1. The disturbance component includes a shell 4 and a column 5. The shell 4 is a hollow cuboid with its two openings sealed by sealing plates. The shell 4 is driven by an electric telescopic rod 6 and slides left and right around the vertical plate 3. The electric telescopic rod 6 is fixed to the outer wall of the upper silo body 1, and its free end extends into the upper silo body 1 and connects to the shell 4. Rotary cylinders 7 are rotatably connected at intervals on the bottom plate of the shell 4. The lower ends of the rotating cylinders 7 extend into the lower silo body 2. The rotating cylinders 7 are cylindrical with openings at the top. Each rotating cylinder 7 has a sealing shaft at its upper end. The base plate of the housing 4 is rotatably connected to the bearing 17. Multiple horizontal disturbance rods 8 are provided on the outer wall of the rotating cylinder 7. The column 5 is slidably disposed inside the rotating cylinder 7. The column 5 is a cylinder with a diameter corresponding to the inner diameter of the rotating cylinder 7. A drive column 9 is provided on the lower part of the peripheral wall of the column 5. The drive column 9 extends into the spiral groove 10 opened in the inner wall of the rotating cylinder 7. The upper end of the spiral groove 10 penetrates the upper end of the rotating cylinder 7. The drive column 9 is a cylinder that slides in contact with the spiral groove 10. A U-shaped groove 11 is recessed downward on the top surface of the column 5. The upper end and left and right ends of the U-shaped groove 11 are open. The upper end of the column 5 extends out of the rotating cylinder 7. The upper part of the U-shaped groove 11 is movably locked outside the upright plate 3. The upright plate 3 is provided with an oblique hole 13 corresponding to the U-shaped groove 11, which is higher on the left and lower on the right. The oblique hole 13 is a long strip-shaped through hole. A drive rod 12 is slidably disposed in the oblique hole 13. The two ends of the drive rod 12 extend out of the oblique hole 13 and connect to the column 5 on the front and rear sides of the oblique hole 13.

[0015] The left and right closed ends of the housing 4 are provided with through holes 14 that fit around the upright plate 3. A sealing ring 15 is fixed on the through hole 14 and slides in contact with the outer side of the upright plate 3. The sealing ring 15 is a ring-shaped body made of elastic rubber to prevent material from entering the housing 4. The outer top surface of the housing 4 is an arc-shaped surface with a raised surface to prevent material accumulation.

[0016] The rotating cylinder 7 includes a first cylinder 7a and a second cylinder 7b, which are alternately arranged along the length of the shell 4. A second cylinder 7b is provided between every two adjacent first cylinders 7a. The spiral groove 10 includes a first groove 10a and a second groove 10b with opposite rotation directions. The first groove 10a is opened inside the first cylinder 7a, and the second groove 10b is opened inside the second cylinder 7b.

[0017] The disturbance rod 8 located on the outer wall of the first cylinder 7a is rod 8a. Multiple sets of rods 8a are arranged from top to bottom on the first cylinder. Multiple rods 8a in the same set are arranged in a ring along the outer wall of the first cylinder 7a. Between two adjacent sets of rods 8a, on the outer wall of the second cylinder 7b on one side, a set of rods 8b is arranged. Multiple rods 8b in the same set are arranged in a ring along the outer wall of the second cylinder 7b. The first rods 8a and the second rods 8b are staggered, which can disturb the quartz sand material at different heights and improve the disturbance range. Both the first rods 8a and the second rods 8b are round rods made of high manganese steel. The rotating cylinder 7 is a cylinder made of high manganese steel. High manganese steel has wear resistance.

[0018] Each of the drive rods 12 is circumferentially slidably fitted with a sleeve 16. The sleeve 16 is located in the U-shaped groove 11 where the drive rod 12 is located. The outer wall of the sleeve 16 makes rolling contact with the side of the inclined hole 13 where the drive rod 12 is located, which can reduce the friction between the drive rod 12 and the inclined hole 13.

[0019] The distance between the upper and lower ends of the U-shaped groove 11 is greater than the distance between the upper and lower ends of the oblique hole 13; when the housing 4 moves to the left or right, each oblique hole 13 is located inside the housing 4.

[0020] In use, the lower end opening of the lower chamber 2 of this utility model is connected to the feed port of the roller crusher, and the quartz sand raw material is put into the upper chamber 1 through the upper end opening of the upper chamber 1. As the quartz sand raw material falls into the upper chamber 1 and lower chamber 2, the electric telescopic rod 6 extends, driving the housing 4 to move to the left. Cylinder 1 7a and Cylinder 2 7b move to the left along with the housing 4, disturbing the quartz sand material. Each column 5 moves to the left along with the housing 4. Since the drive rod 12 on the column 5 is located within the inclined hole 13, which is in a left-high, right-low position, as the column 5 moves to the left, guided by the inclined hole 13, the drive rod 12 drives the connected column 5 to move upward. The drive column 9 on the column 5 moves upward, pressing against the trough 10a in cylinder 1 7a or the trough 10b in cylinder 2 7b. Both cylinder 1 7a and cylinder 2 7b rotate circumferentially. Furthermore, due to the... Since the spirals rotate in opposite directions, the rotation direction of the cylinder 7a and the rod 8a connected to it is opposite to the rotation direction of the cylinder 7b and the rod 8b connected to it. Both rods 8a and 8b can disturb the falling quartz sand material at multiple angles, making it difficult for the quartz sand material to form a balanced structure. Similarly, the electric telescopic rod 6 drives the housing 4 to move to the right, and the cylinders 7a and 7b move to the right, disturbing the quartz sand material. Multiple columns 5 move downwards, and the drive column 9 on the columns 5 drives either cylinder 7a or cylinder 7b to rotate. The rotation directions of cylinders 7a and 7b are opposite, and the rotation of rods 8a and 8b disrupts the balanced structure of the quartz sand material. Therefore, this invention can prevent the quartz sand material from arching and clogging in the flow stabilization chamber.

However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
