Description

Technical Field

[0001] This utility model relates to the field of barite powder production technology, specifically to a vibrating screen feeding adjustment device for barite powder production. Background Technology

[0002] Barite powder is an inorganic mineral powder made from natural barium sulfate ore (barite) through processing. Its chemical formula is BaSO4, and it has unique physical properties. Barite powder has a wide range of applications in oil and gas drilling, chemical production, and coatings. Natural barium sulfate ore needs to be ground and crushed, and then screened and graded by a vibrating screen to obtain qualified barite powder.

[0003] When using a vibrating screen to screen crushed barite granules, the fixed feed inlet diameter makes it difficult to control the amount and speed of the granules being fed. As a result, a large amount of barite granules will quickly accumulate on the vibrating screen, affecting the movement of the granules and thus the screening effect and efficiency of the barite granules. Summary of the Invention

[0004] This invention addresses the problem of difficulty in adjusting the feed inlet size of a vibrating screen when screening barite granules. It provides a feeding adjustment device for a vibrating screen used in barite powder production, which can conveniently control the amount and speed of granule feed, thereby improving screening efficiency and effectiveness.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A feeding adjustment device for a vibrating screen used in barite powder production includes a vibrating screen housing with a feed pipe connected to it; it also includes movable plates and control components. The feed pipe is a rectangular tube, and movable plates are symmetrically arranged on the left and right sides of the feed pipe. The upper end of the left movable plate is hinged to the upper end of the left inner wall of the feed pipe, and the lower ends of the two movable plates are close to or far apart. The control components include rotating rods and top plates. A rotating rod is rotatably provided on the lower side of each movable plate, and a top plate is connected to the upper end of the peripheral wall of each of the two rotating rods. The free end of the left top plate slides in contact with the left side of the left movable plate. The feed pipe is provided with a driving component that drives the two rotating rods to rotate relative to or away from each other. The relative rotation of the two rotating rods drives the lower ends of the two movable plates to approach each other until they contact.

[0007] Furthermore, the front and rear ends of each of the movable plates slide in contact with the front and rear inner walls of the feed pipe, respectively; counterweight rods are connected to the lower ends of the opposite sides of the two movable plates.

[0008] Furthermore, the two top plates are symmetrical from left to right; when the free ends of the two top plates press against the opposite sides of the movable plates on the same side until the lower ends of the two movable plates are in contact, the angle between the left side of the left movable plate and the horizontal plane is α, where α equals 45°, and the angle between the right side of the left top plate and the horizontal plane is β, where β is greater than 45° and less than 90°.

[0009] Furthermore, the front end of each of the rotating rods is rotatably connected to the front side plate of the feed pipe, and the rear end is movably connected to the rear side plate of the feed pipe.

[0010] Furthermore, the driving component includes a driving rod and a hydraulic cylinder. The left side of the rotating rod outside the feed pipe has a spiral groove one, and the right side of the rotating rod has a spiral groove two. The spiral groove one and spiral groove two have opposite rotation directions. The driving rod is located on the rear side of the feed pipe. The left and right parts of the driving rod are slidably sleeved on the left and right rotating rods through through holes one and two, respectively. The inner wall of through hole one has a driving block one that slides into spiral groove one, and the inner wall of through hole two has a driving block two that slides into spiral groove two. A hydraulic cylinder with the piston end facing rear and connected to the driving rod is fixed on the outer side of the rear side of the feed pipe.

[0011] Furthermore, a viewing window is provided on the front side plate of the feed pipe, and the viewing window is opposite to the two movable plates.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] This invention controls the relative rotation of two rotating rods, causing the free ends of two top plates to move relative to each other. Each top plate presses against the movable plate on the same side, causing the lower ends of the two movable plates to contact each other, thereby blocking the feed pipe. By controlling the two rotating rods to rotate in opposite directions, the lower ends of the two movable plates move away from each other, allowing the barite granules to be screened to be fed between the lower ends of the two movable plates. Controlling the opening between the lower ends of the two movable plates allows for control of the feeding amount, facilitating control of the feeding amount and speed of the granules, preventing the barite granules from accumulating in the vibrating screen, and improving screening efficiency and effect.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] like Figures 1-5 As shown, a vibrating screen feeding adjustment device for barite powder production includes a vibrating screen housing 1, a feed pipe 2 connected to the vibrating screen housing 1, and a feed hopper 3 at the upper end of the feed pipe 2; it also includes movable plates 4 and control components. The feed pipe 2 is a rectangular pipe, and movable plates 4 are symmetrically arranged on the left and right sides of the feed pipe 2. The movable plates 4 are rectangular plates. The upper end of the left movable plate 4 is hinged to the upper end of the left inner wall of the feed pipe 2 via a hinge shaft 11. The lower ends of the two movable plates 4 are close to or far apart. The control components include rotating rods 5 and top plates 6. A rotating rod 5 is rotatably provided on the lower side of each movable plate 4. The rotating rod 5 is a round rod. The upper end of the peripheral wall of each of the two rotating rods 5 is connected to the top plate 6. The top plate 6 is a rectangular plate. The free end of the left top plate 6 slides in contact with the left side of the left movable plate 4. The feed pipe 2 is provided with a driving component that drives the two rotating rods 5 to rotate relative to or away from each other. The relative rotation of the two rotating rods 5 is used to drive the lower ends of the two movable plates 4 to approach each other until they contact.

[0022] The front and rear ends of each of the movable plates 4 respectively slide in contact with the front and rear inner walls of the feed pipe 2; a counterweight rod 7 is connected to the lower end of the opposite sides of the two movable plates 4.

[0023] The two top plates 6 are symmetrical from left to right. When the free ends of the two top plates 6 press against the opposite sides of the movable plates 4 on the same side until the lower ends of the two movable plates 4 are in contact, the angle between the left side of the left movable plate 4 and the horizontal plane is α, where α equals 45°, and the angle between the right side of the left top plate 6 and the horizontal plane is β, where β is greater than 45° and less than 90°. The purpose is to ensure that the two top plates 6 can press against the two movable plates 4 until the lower ends are in contact.

[0024] The front end of each of the rotating rods 5 is rotatably connected to the front side plate of the feed pipe 2, and the rear end is movable through the rear side plate of the feed pipe 2.

[0025] The driving component includes a driving rod 8 and a hydraulic cylinder 9. The left side of the rotating rod 5 outside the feed pipe 2 has a spiral groove 10, and the right side of the rotating rod 5 has a spiral groove 12. The spiral grooves 10 and 12 rotate in opposite directions. The driving rod 8 is a rectangular rod located behind the feed pipe 2. The left and right parts of the driving rod 8 are slidably fitted onto the left and right rotating rods 5 through through holes 13 and 14, respectively. The inner wall of through hole 13 has a driving block 15 that slides into the spiral groove 10, and the inner wall of through hole 14 has a driving block 16 that slides into the spiral groove 12. Hole 13 and through hole 2 14 are both circular holes that correspond to the rotating rod 5. A hydraulic cylinder 9 with its piston end facing backward and connected to the drive rod 8 is fixed on the outer side of the rear side of the feed pipe 2. The rear end of spiral groove 10 passes through the rear end of the left rotating rod 5, and the rear end of spiral groove 2 12 passes through the rear end of the right rotating rod 5. The spiral groove 10 of this utility model rotates to the right and the spiral groove 2 12 rotates to the left. When the drive rod 8 moves forward, the two rotating rods 5 rotate relative to each other. When the drive rod 8 moves backward, the two rotating rods 5 rotate in opposite directions. When the piston end of the hydraulic cylinder extends to its limit, the drive rod 8 moves backward to near the rear end of the rotating rod 5.

[0026] The feed pipe 2 has a viewing window 17 on its front side plate, which is opposite to the two movable plates 4. The viewing window 17 is used to observe the opening and closing degree of the two movable plates 4.

[0027] In operation, the hydraulic cylinder 9 drives the drive rod 8 forward, causing the two rotating rods 5 to rotate relative to each other. The free ends of the two top plates 6 move closer together, and each movable plate 4 is pressed against the free end of the top plate 6 on the same side. The lower ends of the two movable plates 4 move closer together until they contact each other. At this point, the inside of the feed pipe 2 is blocked by the two movable plates 4. The barite granules to be screened are fed into the feed pipe 2 through the feed hopper 3. The barite granules are temporarily stored in the feed pipe 2 above the two movable plates 4. Then, the piston end of the hydraulic cylinder 9 drives the drive rod 8 to move backward, causing the two rotating rods 5 to rotate in opposite directions. The free ends of the two top plates 6 move in opposite directions. Under the action of the counterweight rod 7 and its own weight, the left movable plate 4 moves towards the feed. The hinge of pipe 2 rotates clockwise. Similarly, the movable plate 4 on the right rotates counterclockwise around the hinge with the feed pipe 2. The lower ends of the two movable plates 4 move away from each other. The barite granules temporarily stored on the upper side of the two movable plates 4 flow downward between the lower ends of the two movable plates 4, and then enter the vibrating screen housing 1 through the lower end of the feed pipe 2. The distance between the lower ends of the two movable plates 4 and the amount of barite granules fed between the two movable plates 4 can be observed through the viewing window 17. After the appropriate opening between the two movable plates 4 is reached, the hydraulic cylinder 9 stops working. Therefore, this utility model can control the size of the opening at the lower end of the two movable plates 4 by controlling the opposite rotation of the two rotating rods 5, thereby controlling the amount of material fed and preventing the barite granules from accumulating in the vibrating screen.

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.
