Description

Technical Field

[0001] This invention relates to vibrating screen technology, specifically a vibrating screen with a rotatable screen. Background Technology

[0002] A vibrating screen works by utilizing the reciprocating rotary vibration generated by a vibrator. The upper rotating weight of the vibrator causes the screen surface to produce planar rotary vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. The combined effect of these two components is to produce a complex rotary vibration on the screen surface.

[0003] In the existing technology, the screen aperture size of the vibrating screen is fixed and cannot be changed. When screening solid particles of different sizes, the screening plate needs to be replaced manually. There is a possibility of error in replacing the screening plate during manual operation, which may result in the replacement screening plate not meeting the requirements. Furthermore, the vibrating screen and screening plate may be damaged due to operational errors during the manual replacement process.

[0004] To address the aforementioned technical problems, this application proposes a solution. Summary of the Invention

[0005] The purpose of this invention is to automatically switch between screens of different mesh sizes according to a set program and screening requirements through an automatic screen changing function. This reduces manual intervention, improves work efficiency, and reduces the risk of equipment failure caused by human error during screen changing. Appropriate mesh size can reduce wear on the screen, extend its service life, and improve the reliability and service life of the equipment. This invention solves the problems of fixed mesh size being inconvenient for screening and manual replacement being prone to damage. Therefore, it proposes a vibrating screen machine with a rotatable screen.

A discharge pipe is installed inside the support frame at the position corresponding to the collecting hopper two. A guide trough is installed at the upper end of the discharge pipe inside the support frame. An air blowing component is located inside the support frame on one side corresponding to the collecting hopper two.

[0008] In a preferred embodiment of the present invention, the screening component two has the same structure as the screening component one. The screening component one includes a connecting plate, and screening supports are installed at the four corners of the connecting plate. Screening plates are installed on the four sides of the cuboid structure formed by the screening supports and the connecting plate. A measuring box is installed on the side of the screening plate near the inner side of the cuboid structure formed by the screening supports and the connecting plate. A receiving hopper is installed on the outer side wall of the screening plate. Four collecting hoppers are installed inside the cuboid structure formed by the screening supports and the connecting plate at the positions corresponding to the receiving hoppers.

[0009] In a preferred embodiment of the present invention, a screening frame is installed on the inner side of the support frame at the positions corresponding to the screening component one and the screening component two. A rotating shaft is installed on the inner side wall of the screening frame at the center position of the two connecting plates. A rotating motor is installed on one side of the inner side wall of the screening frame. A drive gear wheel is installed near the outer side of the screening frame at the output end of the rotating motor. A transmission gear wheel is installed near the outer side of the screening frame on the outer side wall of the rotating shaft. The drive gear wheel and the transmission gear wheel are connected by a transmission belt.

[0010] In a preferred embodiment of the present invention, a vibration motor is installed on one side of the upper surface of the screening frame corresponding to the position of the connecting plate. Screening brackets are installed at the four corner positions of the screening frame installed on the outside of the screening component one and the screening component two. A telescopic cylinder is installed on the outer wall of the screening bracket through the mounting plate. A guide hopper is installed on the output end of the telescopic cylinder. A discharge hopper is installed inside the support frame corresponding to the lower end position of the guide hopper. A screen hole baffle is provided at the middle position of the outer wall of the screening plate.

[0011] As a preferred embodiment of the present invention, a screen diameter adjustment component is further provided on the inner side wall of the plugging plate. The screen diameter adjustment component includes a data acquisition module, a data processing module, and a data execution module;

[0012] The data acquisition module collects the size data of the solid particulate material at the position of the feeding suction pipe, collects the aperture data of the sieve holes on several sieve plates of the screening component, and transmits the collected material size data and aperture data to the data processing module;

[0013] The data processing module receives the material size data and aperture data transmitted from the data acquisition module, processes the data, generates corresponding signals according to the processing results, and transmits the signals to the data execution module;

[0014] The data processing steps of the data processing module are as follows:

[0015] Step 1: Perform grayscale processing on the pictures of the solid particulate material collected by the data acquisition module, then detect the size of the shadow area on the photo, calculate the diameter of the material, and perform an operation of removing extreme values and averaging the multiple calculated material diameter size data to obtain the material diameter average value A, the maximum value Amax, and the minimum value Amin;

[0016] Step 2: Detect the sieve hole sizes of the sieve plates on several sides of the screening component. The data processing module marks the several sides corresponding to the screening component as Y1, Y2, Y3, Y4,..., Yn, where n is a natural constant, records the aperture sizes of the sieve holes on each side, and corresponds them to the corresponding sides one by one. Then, Y1, Y2, Y3, Y4,..., Yn are arranged in the clockwise order of installation, and the arrangement order is recorded;

[0017] Step 3: If Amax>X>Amin, start the material screening operation, and judge the size relationship between the material diameter X and the material diameter average value A. Otherwise, an alarm is issued through the warning light for error reporting; if X>A or X<A, it is determined to remove the part with more impurities first, and a signal for removing more impurities is generated; if X = A, it is determined to remove the part with less impurities first, and a signal for removing less impurities is generated;

[0018] The data execution module receives the execution signal transmitted from the data processing module and controls the corresponding components to complete the corresponding execution operations.

[0019] As a preferred embodiment of the present invention, the steps for the data execution module to perform the execution operation are as follows:

[0020] Step 1: After receiving the de-duplication execution signal, the data processing module determines that the diameters of the screen holes at the bottom of the screening components from top to bottom should be adjusted to A, X+n, and Xn in sequence. First, the materials with a larger quantity of diameter A are removed. Then, the materials are finely screened through the screening plate. Based on the screen hole diameter of the bottom screening plate of the screening component collected by the data acquisition module, the data processing module determines the screen hole diameter of each of the other screening plates in a clockwise order. Then, the data processing module transmits a signal to the rotation motor of each corresponding screening component. The rotation motor rotates by the corresponding angle to rotate the screening plate with the appropriate hole diameter to the bottom.

[0021] Step 2: After receiving the signal to remove impurities, the data processing module adjusts the diameter of the lower screen holes on the top-to-bottom screening components to X+n, Xn, and A in sequence. It first removes a small number of materials that do not meet the size requirements. The rest of the operation is the same as in Step 1.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] The automatic screen changing function can automatically switch between screens with different screen aperture sizes according to the set program and screening requirements, reducing manual intervention and improving work efficiency. In addition, the automatic screen changing function can reduce human operation during the screen changing process, reducing the risk of equipment failure caused by human operation. Appropriate screen aperture size can reduce wear on the screen, extend the service life of the screen, and improve the reliability and service life of the equipment. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1:

[0034] Please see Figure 1-6As shown, a rotatable vibrating screen includes a support frame 9, which is divided into three layers. The top layer houses a screening component 22 and a feed hopper 3, the middle layer houses a screening component 26, and the bottom layer houses a material container 10. Sealing plates 1 are installed at various grid positions on the outer wall of the support frame 9, covering six sides of the support frame 9 to reduce the impact of the external environment on the screening components 22 and 26. Several observation ports 6 are provided on the outer wall of the sealing plates 1, allowing workers to observe whether the various parts of the screening operation inside the support frame 9 are working properly. The observation ports 6 also facilitate the maintenance and inspection of the screening components. A feed hopper 3 is installed at the top of the 9th internal structure. The upper opening of the feed hopper 3 allows for material feeding. A star valve flow regulator is installed at the lower end of the feed hopper 3, which can regulate and control the flow of material at the feed hopper 3. A cleaning fan 4 is installed on one side of the outer wall of the feed hopper 3. The cleaning fan 4 is connected to the discharge pipe 5. When the cleaning fan 4 is working, it can remove and discharge impurities from the material inside the feed hopper 3 through the discharge pipe 5. The discharge pipe 5 is installed at the end of the cleaning fan 4 away from the feed hopper 3. A transmission chamber 2 is set on one side of the outer wall of the sealing plate 1. A base plate is installed at the bottom of the support frame 9. Three material collection cylinders 10 are installed on the base plate. The lower end of the discharge hopper 21 is aligned with the material collection cylinders 10, allowing the discharged material to be discharged. The material is conveyed into the receiving cylinder 10 for storage. Inside the support frame 9, near the bottom of the feed hopper 3, is a screening component 1 22. Inside the support frame 9, near the bottom of screening component 1 22, is a screening component 26. Both screening components 1 22 and 26 are arranged at an angle and are connected by a screening bracket 27. They have the same angle of inclination. Inside the support frame 9, corresponding to the middle position between screening components 1 22 and 26, is a collecting hopper 1 23. The length and width of collecting hopper 1 23 are greater than the length and width of screening component 1 22, allowing material screened by screening component 1 22 to fall into collecting hopper 1 23. Inside the support frame 9, corresponding to screening component 2 26... A second collection hopper 24 is installed below. A discharge pipe 7 is installed inside the support frame 9 at the position corresponding to the second collection hopper 24. A guide chute 8 is installed at the upper end of the discharge pipe 7 inside the support frame 9. The length and width of the second collection hopper 24 are greater than the length and width of the second screening component 26, ensuring that all materials screened by the second screening component 26 fall into the second collection hopper 24. Vibration devices are installed on the outside of both the first collection hopper 23 and the second collection hopper 24 to ensure that materials do not adhere and flow smoothly into the next receiving device. An air blowing component 25 is installed inside the support frame 9 on one side corresponding to the second collection hopper 24. The air blowing component 25 is connected to an external air supply device. When opened, it removes materials adhering to the second collection hopper 24 through the propulsion of airflow.The number of screening components inside the support frame 9 and the number of screening plates 29 installed on the outside of the screening components can be changed according to the user's own needs;

[0035] Screening component 26 has the same structure as screening component 1 22, both being cuboid structures. The top and bottom surfaces are respectively configured as material outlets and material inlets. The material inlet is located on one side of the upper surface of both screening components 26 and 22, and the material outlet is located on the other side of the lower surface. Screening plates 29 with different diameter screen holes are mounted on the top, bottom, front, and back surfaces. The screen hole portion is located in the middle of the screening plate 29, and grooves are provided on the outer side of the screening plate 29 corresponding to the screen hole portion. The size of the grooves is the same as the size of the screen hole baffle 210. Screening component 1 22 includes a connecting plate 220, with recesses in all four directions. The trough facilitates the flow of screened materials from one end. Screening supports 218 are installed at the four corners of the connecting plate 220. Screening plates 29 are installed on the four sides of the cuboid structure formed by the screening supports 218 and the connecting plate 220. A measuring box 219 is installed on the side of the screening plate 29 closest to the inner side of the cuboid structure formed by the screening supports 218 and the connecting plate 220. A receiving hopper 28 is installed on the outer side of the screening plate 29. Four collecting hoppers 217 are installed inside the cuboid structure formed by the screening supports 218 and the connecting plate 220 at the positions corresponding to the receiving hopper 28. The four collecting hoppers 217 allow the rotating screening component 22 to receive materials from the top.

[0036] Screening frames 215 are installed on the inner side of the support frame 9 at the positions corresponding to screening component 1 22 and screening component 26. Screening component 1 22 and screening component 26 are positioned through screening frames 215, and the tilt angle inside the support frame 9 can be adjusted by an adjustment device. Adjusting the tilt angle adjusts the screening speed of screening component 1 22 and screening component 26. A rotating shaft 216 is installed on the inner wall of the screening frame 215 at the center position of the two connecting plates 220. A rotating motor 212 is installed on one side of the inner wall of the screening frame 215. A drive gear wheel 221 is installed near the outer side of the screening frame 215 at the output end of the rotating motor 212. A transmission gear wheel 222 is installed near the outer side of the screening frame 215 on the outer wall of the rotating shaft 216. The drive gear wheel 221 and the transmission gear wheel 222 are connected by a transmission belt. The inner side of the transmission belt is provided with protruding teeth to prevent slippage when the drive gear wheel 221 drives the transmission gear wheel 222 to rotate.

[0037] A vibration motor 211 is installed on one side of the upper surface of the screening frame 215 corresponding to the position of the connecting plate 220. Screening brackets 27 are installed at the four corners of the screening frame 215 installed on the outside of the screening component 1 22 and the screening component 26. A telescopic cylinder 213 is installed on the outer wall of the screening bracket 27 through the mounting plate. A guide hopper 214 is installed on the output end of the telescopic cylinder 213. The telescopic cylinder 213 can adjust the position of the guide hopper 214. The position adjustment of the guide hopper 214 is adjusted according to the tilt angle of the screening component 1 22 and the screening component 26, so that the material sliding out from one end of the screening component 1 22 and the screening component 26 can fall into the guide hopper 214 without any leakage. A discharge hopper 21 is installed inside the support frame 9 corresponding to the lower end of the guide hopper 214. A screen hole baffle 210 is set in the middle of the outer wall of the screening plate 29.

[0038] The sieve diameter adjustment component includes a data acquisition module, a data processing module, and a data execution module;

[0039] The data acquisition module detects the size of the sieve holes on the four sides of the screening plate 29 of the screening component 1 22 and the screening component 26. The data acquisition module marks the four sides corresponding to the screening component 1 22 and the screening component 26 as Y1, Y2, Y3, Y4, R1, R2, R3 and R4, and records the size of the sieve hole on each side and matches it with the corresponding side. Then, Y1, Y2, Y3, Y4 and R1, R2, R3, R4 are arranged in a clockwise order according to the installation and the arrangement order is recorded.

[0040] When the vibrating screen is screening materials, the inside of the feeding pipe can take pictures of the materials while the material is being sucked up. The pictures are then processed in grayscale, and the size of the shadow area on the picture is detected to calculate the diameter of the material. The average value of the material diameter is obtained by removing extreme values ​​from multiple calculated material diameter data. The mean diameter A, maximum value Amax and minimum value Amin of the material diameter are obtained.

[0041] The diameter of the material required by the user is X. Determine the size of the material diameter X with the maximum value Amax and the minimum value Amin. If Amax > X > Amin, start the material screening operation and determine the size relationship between the material diameter X and the average diameter A of the material. Otherwise, sound an alarm through the warning light and report an error. If X > A or X < A, it is determined that the diameters of the screening holes located below on the screening component from top to bottom are adjusted to A, X + n, and X - n in sequence, where n is a natural constant. First, remove the materials with a diameter of A in a larger quantity, and then conduct a detailed screening of the materials through the screening plate 29. If X = A, it is determined that the diameters of the screening holes located below on the screening component from top to bottom are adjusted to X + n, X - n, and A in sequence, and first remove the materials with unqualified sizes in a smaller quantity.

[0042] During size adjustment, the data acquisition module first detects the aperture size of the screening plate 29 at the downward position on the screening component, determines which surface of the corresponding screening component the aperture size is, and determines the required aperture size for screening by the screening component. Then, select the surface closest to the required aperture from the four surfaces, determine the position between this surface and the downward surface, and rotate the surface closest to the required aperture to the bottom in the fastest way.

[0043] In the prior art, the aperture size of the screening holes of the vibrating screen is fixed and cannot be changed. When screening solid particles of different particle sizes, it is necessary to manually replace the screening plate 29. There is a possibility of errors during manual replacement, resulting in the replaced screening plate 29 not meeting the requirements. Moreover, the vibrating screen and the screening plate 29 may be damaged due to operational errors during manual replacement.

[0044] Solid particle materials enter from the position of the feed hopper 3, and the flow rate is adjusted and controlled by the star valve flow regulating device below the feed hopper 3. After the flow rate of the solid particle materials is evenly adjusted, they flow into the interior of the first screening component 22 through the top single-product flow channel. The number of screening components inside the support frame 9 and the number of screening plates 29 installed outside the screening components can be changed according to the user's own needs. The first screening component 22 is the uppermost screening device. Before the solid particle materials enter the first screening component 22, each screening component has completed rotation according to the program setting, so that the screening plate 29 at the bottom is the most suitable screening aperture. The automatic screen changing function can automatically switch the screens with different aperture sizes according to the set program and screening requirements, reducing manual intervention and improving work efficiency. Moreover, the automatic screen changing function can reduce the manual operation during screen replacement, reducing the risk of equipment failures caused by human operations. Appropriate screen aperture sizes can reduce the wear of the screen, extend the service life of the screen, and improve the reliability and service life of the equipment.

[0045] When the present invention is in use, the data acquisition module detects the sizes of the sieve holes of the sieve plates 29 on the four sides of the first screening component 22 and the second screening component 26. The data acquisition module marks the four sides corresponding to the first screening component 22 and the second screening component 26 as Y1, Y2, Y3, Y4, R1, R2, R3, and R4, records the aperture sizes of the sieve holes on each side, and corresponds them one by one with the corresponding sides. Then, Y1, Y2, Y3, Y4 and R1, R2, R3, R4 are arranged in the clockwise order of installation, and the arrangement order is recorded. When the vibrating screen is performing the material screening operation, when the feeding suction pipe is sucking materials inside, the photographing device inside the feeding suction pipe can take pictures of the materials, perform grayscale processing on the taken pictures, then detect the size of the shadow area on the pictures, calculate the diameter sizes of the materials, and perform the operation of removing extreme values and calculating the average value on the multiple calculated material diameter size data to obtain the average material diameter A, the maximum value Amax, and the minimum value Amin; the required material diameter size of the user is X. Determine the sizes of the material diameter X, the maximum value Amax, and the minimum value Amin. If Amax > X > Amin, then start the material screening operation and determine the size relationship between the material diameter X and the average material diameter A. Otherwise, an alarm is issued through the warning light for error reporting; if X > A or X < A, it is determined that the diameters of the sieve holes at the lower positions of the screening components from top to bottom are adjusted to A, X + n, and X - n in sequence, where n is a natural constant. First, remove the materials with the diameter size of A in a larger quantity, and then perform a detailed screening of the materials through the sieve plate 29; if X = A, it is determined that the diameters of the sieve holes at the lower positions of the screening components from top to bottom are adjusted to X + n, X - n, and A in sequence, and first remove the materials with unqualified sizes in a smaller quantity;

[0046] During size adjustment, the data acquisition module first detects the aperture size of the sieve plate 29 at the downward position on the screening component, determines which surface of the corresponding screening component the aperture size is, determines the required aperture size for screening by the screening component, then selects the surface closest to the required aperture from the four surfaces, determines the position between this surface and the downward surface, and rotates the surface closest to the required aperture to the bottom in the fastest way;

[0047] Solid particulate material enters from the feed hopper 3. The flow rate is regulated and controlled by the star-shaped valve flow regulator below the feed hopper 3. After uniform adjustment, the solid particulate material flows into the screening component 22 through the top single-item flow channel. Small particulate impurities such as ash are absorbed by the dust removal device at the feed point and then fall into the small particulate impurity collection cylinder 10 after passing through the screen collection channel and the lower screen collection device. The screening component 22 has a cuboid structure. Before the solid particulate material falls in, the downward-facing screening plate 29 of the screening component has been adjusted to a size corresponding to the particulate material. During the material screening process, the screening component... Driven by the vibrating motor 211, the 22 vibrates, which can fully screen the material. After screening, large particles of waste flow out from the material outlet, pass through the guide hopper 214 and the discharge hopper 21, and fall into the large particle impurity collection cylinder 10. The undersize material falls into the collection hopper 23 and then flows into the screening component 26. The structure of the screening component 26 is similar to that of the screening component 22, but the diameter of the screening holes is smaller. After screening, the material on the screen is the desired material, which flows into the material collection bucket through the lower flow plate. The undersize material is small particle waste, which falls into the small particle impurity collection cylinder 10 after passing through the lower screen material collection device.
