Description

Technical Field

[0001] The utility model relates to the technical field of separation equipment, in particular to fine stone powder separation equipment. Background Art

[0002] Fine stone powder is a fine-grained material made from natural stone through mechanical crushing, grinding and other processes. It is widely used in the fields of construction and engineering, especially in concrete and mortar. As a functional filler, it can improve the density, impermeability and wear resistance of concrete, and reduce the risk of shrinkage and cracks. Usually, separation equipment is required during the screening process of fine stone powder. The purpose of the separation equipment is to separate the fine stone powder from the raw materials according to its particle size to ensure the purity and quality of the final product.

[0003] Conventional screening equipment (such as fixed screens and vibrating screens) are usually designed for single-stage operation, which means they can only process materials within one particle size range at a time. This results in uneven particle size distribution of fine stone powder during the screening process, forming substandard products and affecting quality.

[0004] Therefore, those skilled in the art provide a fine stone powder separation device to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a fine stone powder separation device. In the fine stone powder separation device, the staff starts the vibration motor, and the motor drives the secondary separation box and the primary separation box to vibrate. At this time, the return spring is driven by the force to drive the telescopic rod to continuously compress or rebound, thereby cooperating with the secondary separation box and the primary separation box to vibrate while limiting them, ensuring that the separation box remains in a relatively stable state during vibration and will not shift due to excessive vibration. Because the aperture of the first-level screen plate is the largest, relatively small particles of fine stone powder will be screened into the second-level separation box, and the second-level screen plate fixedly connected to the lower end of the inner wall of the second-level separation box will further screen the fine stone powder, and the third-level screen plate fixedly connected to the lower end of the inner wall of the third-level separation box will perform a final screening of the fine stone powder, and then The finest stone powder will enter the drawer that is slidably connected at the lower end of the aggregate box. After completing the preliminary screening, the staff will start the electric telescopic rod to drive the second support frame to lift. The movement of the second support frame will drive the three-stage separation box and the whole to move. The lower end of the first support frame is hinged to the bottom plate to tilt the whole. Then the staff will start the vibration motor and cooperate with the electromagnetic control valve that is controlled one by one to discharge the stone powder left by the screening into the drawer one by one, and then take it out. The entire separation process can effectively separate fine stone powder of different particle sizes through three-stage screening, thereby improving screening efficiency. The use of electric telescopic rods and electromagnetic control valves makes operation easier and reduces labor intensity. The design of sieve plates with different apertures can achieve precise particle size control and ensure product quality.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A fine stone powder separation device comprises a bottom plate, an upper surface of the bottom plate is fixedly connected to a collection box, an upper end of the collection box is provided with a three-stage separation box, the lower end of the inner wall of the three-stage separation box is fixedly connected to a three-stage sieve plate, the other side of the upper surface of the bottom plate is fixedly connected to an electric telescopic rod, the output end of the electric telescopic rod is hingedly connected to a second support frame, the upper end of the three-stage separation box is provided with a secondary separation box, the lower end of the inner wall of the secondary separation box is fixedly connected to the secondary sieve plate, the upper end of the secondary separation box is provided with a primary separation box, the lower end of the inner wall of the primary separation box is fixedly connected to the primary sieve plate, and the front ends of the secondary separation box and the outer walls of the primary separation box are both provided with vibration motors;

[0008] The upper end of the first-level separation box is fixedly connected to a connecting block, and a feed pipe is connected through the center of the upper end of the connecting block.

[0009] Through the above technical solution, when the staff pours the fine stone powder from the feed port, the staff can turn the second handle to rotate the second flow control plate. Because the multiple discharge holes and semicircular holes opened on the upper surface of the first flow control plate correspond to the second flow control plate, when the second flow control plate rotates, the multiple discharge holes and semicircular holes opened on its upper surface will be misaligned with the multiple discharge holes and semicircular holes opened on the upper surface of the first flow control plate, thereby controlling the flow rate of the fine stone powder. Accurate flow rate control helps to improve screening efficiency, reduce material blockage on the screen, and ensure that the particle size distribution of the fine stone powder is more uniform. The staff only needs to turn the second handle to easily adjust the flow rate without the need for complex mechanical operations or professional knowledge.

[0010] Furthermore, a drawer is slidably connected to the lower end of the interior of the collecting box, and a first handle is fixedly connected to the front end of the outer wall of the drawer;

[0011] With the above technical solution, the drawer is more convenient to pull out through the first handle.

[0012] Furthermore, a first support frame is hingedly connected to the middle of one side of the upper surface of the bottom plate, and the other side of the outer wall of the first support frame is fixedly connected to one side of the outer wall of the three-stage separation box;

[0013] Through the above technical solution, the first support frame is used to facilitate improved coordination.

[0014] Furthermore, the lower ends of the outer walls of one side of the three-stage separation box, the two-stage separation box and the first-stage separation box are fixedly connected to a discharge pipe, and the outer walls of the discharge pipes are provided with electromagnetic control valves;

[0015] Through the above technical solution, the opening and closing of the discharge pipe can be freely controlled by the electromagnetic control valve.

[0016] Furthermore, a second handle is fixedly connected to one side of the outer wall of the second flow control piece;

[0017] Through the above technical solution, the second flow control piece can be easily rotated by the second handle.

[0018] Furthermore, the upper end of the second flow control piece is rotatably connected to a feed port;

[0019] By means of the above technical solution, the fine stone powder can enter the separation equipment through the feed port.

[0020] Furthermore, the outer wall of the other side of the second support frame is fixedly connected to the outer wall of the third-stage separation box;

[0021] Through the above technical solution, the equipment is more stable by fixing the outer wall on the other side of the second support frame to the outer wall of the three-stage separation box.

[0022] Furthermore, the upper ends of the telescopic rod and the return spring are fixedly connected to the lower ends of the secondary separation box and the primary separation box respectively;

[0023] Through the above technical solution, the upper ends of the telescopic rod and the return spring are fixedly connected to the lower ends of the secondary separation box and the primary separation box respectively, so that the connection between the equipment structures is closer.

Because the aperture of the primary sieve plate is the largest, relatively small particles of fine stone powder will be screened into the secondary separation box, and the secondary sieve plate fixedly connected to the lower end of the inner wall of the secondary separation box will further screen the fine stone powder, and the tertiary sieve plate fixedly connected to the lower end of the inner wall of the tertiary separation box will perform the final screening of the fine stone powder, and then the finest fine stone powder will enter the collecting In the drawer that is slidably connected at the lower end of the material box, after completing the preliminary screening, the staff starts the electric telescopic rod to drive the second support frame to lift, and the movement of the second support frame drives the three-stage separation box and the whole to move, and the lower end of the first support frame is hingedly connected to the bottom plate to tilt the whole.

[0035] Reference Figure 1-5 , a specific implementation method provided by the utility model:

[0036] A fine stone powder separation device includes a base plate 1, an aggregate box 2 is fixedly connected to the upper surface of the base plate 1, a three-stage separation box 5 is provided at the upper end of the aggregate box 2, a three-stage sieve plate 7 is fixedly connected to the lower end of the inner wall of the three-stage separation box 5, an electric telescopic rod 23 is fixedly connected to the other side of the upper surface of the base plate 1, the output end of the electric telescopic rod 23 is hingedly connected to a second support frame 24, a two-stage separation box 8 is provided at the upper end of the three-stage separation box 5, a two-stage sieve plate 9 is fixedly connected to the lower end of the inner wall of the two-stage separation box 8, a one-stage separation box 12 is provided at the upper end of the two-stage separation box 8, a one-stage sieve plate 13 is fixedly connected to the lower end of the inner wall of the one-stage separation box 12, and a vibration motor 14 is provided at the front end of the outer wall of the two-stage separation box 8 and the one-stage separation box 12;

[0038] When the staff pours the fine stone powder from the feed port 16, the staff can turn the second handle 20 to rotate the second flow control piece 19. Because the multiple discharge holes 21 and semicircular holes 22 opened on the upper surface of the first flow control piece 18 and the second flow control piece 19 correspond to each other, when the second flow control piece 19 rotates, the multiple discharge holes 21 and semicircular holes 22 opened on its upper surface will be misaligned with the multiple discharge holes 21 and semicircular holes 22 opened on the upper surface of the first flow control piece 18, thereby controlling the flow rate of the fine stone powder. Accurate flow rate control helps to improve screening efficiency, reduce material blockage on the screen, and ensure that the particle size distribution of the fine stone powder is more uniform. The staff only needs to turn the second handle 20 to easily adjust the flow rate without the need for complex mechanical operations or professional knowledge.

[0039] The lower end of the inside of the collecting box 2 is slidably connected to the drawer 3, and the front end of the outer wall of the drawer 3 is fixedly connected to the first handle 4, which makes it easier to pull out the drawer 3. The middle part of the upper surface of the bottom plate 1 is hingedly connected to the first support frame 6, and the other side of the outer wall of the first support frame 6 is fixedly connected to one side of the outer wall of the three-stage separation box 5. The first support frame 6 is used to facilitate the improvement of the coordination. The lower ends of the outer walls of one side of the three-stage separation box 5, the secondary separation box 8 and the primary separation box 12 are fixedly connected to the discharge pipe 10, and the outer walls of the discharge pipe 10 are provided with an electromagnetic control valve 11, which can freely control the opening and closing of the discharge pipe 10. One side of the outer wall of the second flow control piece 19 is fixedly connected to the second handle 2 0, the rotation of the second flow control piece 19 is facilitated by the second handle 20, and the upper end of the second flow control piece 19 is rotatably connected to the feed port 16, so that the fine stone powder can enter the separation equipment through the feed port 16, and the outer wall on the other side of the second support frame 24 is fixedly connected to the outer wall of the three-stage separation box 5, and the outer wall on the other side of the second support frame 24 is fixedly connected to the outer wall of the three-stage separation box 5 to make the equipment more stable, and the upper ends of the telescopic rod 25 and the reset spring 27 are respectively fixedly connected to the lower ends of the secondary separation box 8 and the primary separation box 12, and the upper ends of the telescopic rod 25 and the reset spring 27 are respectively fixedly connected to the lower ends of the secondary separation box 8 and the primary separation box 12 to make the connection between the equipment structures closer.

[0040] Working principle: When the staff pours the fine stone powder into the fine stone powder separation equipment from the feed port 16, the staff can rotate the second handle 20 to rotate the second flow control piece 19. Because the multiple discharge holes 21 and semicircular holes 22 opened on the upper surfaces of the first flow control piece 18 and the second flow control piece 19 correspond to each other, when the second flow control piece 19 rotates, the multiple discharge holes 21 and semicircular holes 22 opened on its upper surface will be misaligned with the multiple discharge holes 21 and semicircular holes 22 opened on the upper surface of the first flow control piece 18, thereby controlling the flow rate of the fine stone powder. Accurate flow rate control helps to improve screening efficiency and reduce material blockage on the screen. , to ensure that the particle size distribution of the fine stone powder is more uniform, the staff only needs to turn the second handle 20 to easily adjust the flow rate without complicated mechanical operation or professional knowledge. The staff starts the vibration motor 14, and the motor drives the secondary separation box 8 and the primary separation box 12 to vibrate. Because the aperture of the primary sieve plate 13 is the largest, the relatively small particles of fine stone powder will be screened into the secondary separation box 8, and the secondary sieve plate 9 fixedly connected to the lower end of the inner wall of the secondary separation box 8 will further screen the fine stone powder, and the tertiary sieve plate 7 fixedly connected to the lower end of the inner wall of the tertiary separation box 5 will screen the fine stone powder for the last time, and then the finest fine stone powder will enter the lower end slide of the aggregate box 2. After the preliminary screening is completed, the staff starts the electric telescopic rod 23 to make one side of the separation equipment higher than the other side, and then the staff controls the electromagnetic control valve 11 on the outer wall of the discharge pipe 10 fixedly connected to one side of the outer wall of the tertiary separation box 5, so that the fine stone powder in the tertiary separation box 5 enters the drawer 3, and the staff collects it. Then the staff starts the vibration motor 14 fixedly connected to the front end of the outer wall of the secondary separation box 8 and the electromagnetic control valve 11 on the outer wall of the discharge pipe 10 fixedly connected to one side of the outer wall of the secondary separation box 8. At this time, the fine stone powder in the secondary separation box 8 will enter the drawer 3 through the discharge pipe 10, and the staff After collecting it, the vibration motor 14 fixedly connected to the front end of the outer wall of the first-stage separation box 12 and the electromagnetic control valve 11 on the outer wall of the discharge pipe 10 fixedly connected to one side of the outer wall of the first-stage separation box 12 are started again. At this time, the fine stone powder in the first-stage separation box 12 will enter the drawer 3 through the discharge pipe 10. The staff collects the fine stone powder for the last time. The entire separation process is screened three levels, which can effectively separate fine stone powder of different particle sizes and improve screening efficiency. The use of the electric telescopic rod 23 and the electromagnetic control valve 11 makes the operation easier and reduces the labor intensity. The design of sieve plates with different apertures can achieve precise particle size control and ensure product quality.
