Description

Technical Field

[0001] This invention relates to the field of grain processing equipment technology, and in particular to a grain particle vibrating screen based on automatic feeding. Background Technology

[0002] "Grains" covers a wide range, including rice, wheat, millet, soybeans and other miscellaneous grains. Grains include rice, wheat, millet, soybeans, etc., which are mainly plant seeds and fruits and are the traditional staple food of many Asian people.

[0003] The rotary vibrating screen is a high-precision fine powder screening machine with low noise and high efficiency. It is suitable for screening and filtering materials such as granules, powders, and viscous liquids. The rotary vibrating screen uses a vertical motor as the excitation source. Eccentric weights are installed at the upper and lower ends of the motor to convert the rotational motion of the motor into a three-dimensional motion of horizontal, vertical, and inclined motion, and then transmit this motion to the screen surface.

[0004] Based on the above, it should be noted that: During operation, traditional vibrating screens directly transport and dump grains into the screen. Due to the influence of multiple factors such as the quality of the grains, feeding efficiency, and feeding concentration, as well as the lack of effective supervision and control of the operation process, some abnormal grains may cause problems such as feeding blockage, transportation blockage, and low vibrating screen efficiency. In addition, the traditional vibrating screen only uses mechanical energy to process the grains through contact with the grains. Due to the influence of some waste shells and impurities, some waste shells and impurities may still be mixed in with the finished grains, affecting the overall quality of the processed grains.

[0005] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

Based on these signals, it controls the components within the screen to make adaptive adjustments.

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0036] Example 1:

[0037] This embodiment addresses the problems encountered by traditional vibrating screens during operation, where grain particles are directly transported and dumped into the screen. These problems are influenced by multiple factors, including the quality of the grain particles, feeding efficiency, and feeding concentration, as well as the lack of effective monitoring and control of the operation process. Consequently, some abnormal grain particles may cause problems such as feeding blockage, transportation blockage, and low vibrating screen efficiency.

[0038] Please see Figure 1 - Figure 8As shown, this embodiment is a grain particle vibrating screen based on automatic feeding, including a support frame 1, a primary screening box 3 is provided on the top of the support frame 1, a rotating drum 301 is provided inside the primary screening box 3, a first air pump 303 is provided at one end of the primary screening box 3 near the rotating drum 301, a cone box 304 is provided below the rotating drum 301, and a feeding mechanism 2 is provided on the top of the primary screening box 3.

[0039] The feeding mechanism 2 includes a feeding box 203. A drive box 202 is provided at the bottom of one end of the feeding box 203. A rotating plate 207 is rotatably connected to the bottom of the feeding box 203. A feeding cylinder 8 is provided below the rotating plate 207. Multiple sets of rotating irregular plates 801 are rotatably connected inside the feeding cylinder 8.

[0040] A vibrating screen box 5 is mounted at the bottom of the support frame 1. A control panel 4 is mounted at the top of one end of the vibrating screen box 5. An inclined frame 501 is mounted at the top of the vibrating screen box 5. An inclined material inlet 505 is mounted at the bottom of the other end of the inclined frame 501. A secondary screening box 6 is mounted on the end face of the inclined material inlet 505. A vertical air jet 604 is mounted inside the secondary screening box 6. A slag removal mechanism 7 is mounted on the end face of the secondary screening box 6 near the vertical air jet 604.

[0041] The control panel 4 is equipped with a processor, a data acquisition module, a self-test feedback module, and a signal execution module. The data acquisition module acquires the blockage ratio value Qu and the discharge ratio value Wu of the vibrating screen within the time threshold. The blockage ratio value Qu and the discharge ratio value Wu are sent to the self-test feedback module via the processor, and 30 minutes of the vibrating screen's running time is set as the time threshold.

[0042] It should be noted that: the blockage ratio value Qu represents the maximum and minimum flow rates of grain particles in the vibrating screen after automatic feeding within a time threshold. The value of the blockage ratio value Qu reflects the smoothness and speed of the grain particle processing. The larger the value, the more abnormal the grain particle processing in the vibrating screen. The discharge ratio value Wu represents the proportion of finished grain particles and waste shells and impurities discharged from the vibrating screen. In addition, the blockage ratio value Qu is collected by multiple sets of flow sensors and industrial cameras installed in the vibrating screen, and the discharge ratio value Wu is collected by metering sensors installed in the waste bin 705, discharge port 504 and screw discharge port 603 in the vibrating screen.

[0043] After receiving the blockage ratio value Qu and the discharge ratio value Wu, the self-test feedback module immediately analyzes the vibrating efficiency of the rotary vibrating screen. The specific analysis process is as follows:

[0044] The percentage of the piston movement (Qu) and the percentage of the output (Wu) of the vibrating screen within the time threshold are obtained, and then processed by the formula... The screening coefficient Fo is obtained, where a and b are the proportional coefficients of the block ratio Qu and the output ratio Wu, respectively, a>b>0, and Fo represents the vibrating screen efficiency. The preset vibrating screen efficiency Yo stored in the processor is immediately retrieved and compared with the vibrating screen efficiency Fo for analysis.

[0045] If the vibrating screen efficiency Fo ≥ the preset vibrating screen efficiency Yo, it is determined that there is an abnormality in the process of transporting and screening grain particles in the vibrating screen. An adjustment signal is generated and sent to the signal execution module via the processor. After receiving the adjustment signal, the signal execution module immediately controls the first air pump 303 to work. The pipeline of the first air pump 303 is connected to the adjustment cylinder. The adjustment cylinder drives the telescopic arc plate 205 to slide along the inner wall of the bottom of the feeding box 203, adjusting the outward extension length of the telescopic arc plate 205 near the discharge port. The pressure is reduced, thereby reducing the size of the discharge port. At the same time, the first air pump 303 is connected to the expansion air bladder 206 via pipeline, reducing the air supply to the expansion air bladder 206. After the expansion air bladder 206 loses pressure, the telescopic line 209 resets and pulls the expansion air bladder 206 to shrink and collapse, causing the space inside the feeding box 203 to increase. The accumulation of coarse grains in the feeding box 203 reduces the feeding efficiency to the discharge cylinder 8 and delays the feeding efficiency inside the vibrating screen, so that the grain particles that have been fed into the vibrating screen can be fully processed by the vibrating screen.

[0046] Simultaneously, the first air pump 303 is connected to the conical nozzle 309 via pipeline and provides airflow to it. The airflow is ejected along the conical nozzle 309 and blown into the rotating drum 301, causing the grain particles, waste husks and impurities falling into the rotating drum 301 to be separated under the mechanical force of the airflow and the rotation of the rotating drum 301. The heavier grain particles and impurities fall into the vibrating screen box 5 along the cone box 304. Meanwhile, the first air pump 303 is connected to the waste slag outlet 1 306 and waste slag outlet 2 308 via pipeline to draw air from the cone box 304. The waste husks are drawn into the waste slag outlet 1 306 and waste slag outlet 2 308 by the airflow. The grain particles, waste husks and impurities that are close to the waste slag outlet 1 306 and waste slag outlet 2 308 are intercepted by the rebound screen 305 and the inclined screen frame 307, causing the waste husks to enter the outlet with the airflow. The grain particles and impurities collide with the outlet and rebound into the discharge outlet 2.

[0047] If the vibrating screen efficiency Fo is less than the preset vibrating screen efficiency Yo, no signal will be generated.

[0048] Example 2:

[0049] This embodiment addresses the problem that when using only the mechanical energy provided by a traditional vibrating screen for contact processing of grain particles through body collision, the finished grain particles still contain some waste shells and impurities due to the influence of some waste shells and impurities, thus affecting the overall quality of the processed grain particles.

[0050] Please see Figure 1 -Figure 4 As shown, the grain particle vibrating screen based on automatic feeding in this embodiment includes a feeding frame 101 that is snapped into a feeding box 203 at the top of one end of the support frame 1. A feeding port is opened at the top of one end of the feeding box 203. An arc-shaped sliding plate 204 is slidably installed on the inner wall of the feeding box 203 at the top of the feeding port. A discharge port is opened at the bottom of the other end of the feeding box 203. A rotating plate 207 is rotatably connected to the inner wall of the feeding box 203 at the top of the discharge port. A guide plate 208 is provided on the outer wall of the rotating plate 207. Side supports 201 connected to the primary screening box 3 are provided on both sides of the feeding box 203.

[0051] A telescopic arc plate 205 is embedded in the inner wall of the feed box 203 near the drive box 202, and an adjusting cylinder connected to the telescopic arc plate 205 is provided on the top of the drive box 202. An expansion airbag 206 is snapped onto the top of the telescopic arc plate 205. Multiple telescopic lines 209 are provided inside the expansion airbag 206, and the other end of the telescopic lines 209 is connected to the inner wall of the feed box 203. The manually adjusted arc-shaped sliding plate 204 is inserted into the top of the feed box 203, opening the feed inlet 1. Grain particles are transported and fed into the feed box 203 by external devices. The first air pump 303 provides airflow to the expansion airbag 206 for pressurization and expansion. The expansion airbag 206 expands and reduces the internal space of the feed box 203. The adjusting cylinder drives the telescopic arc plate 205 to slide and retract along the bottom of the feed box 203, causing the discharge port 1 to open gradually.

[0052] The feeding cylinder 8 has side suspension plates 807 fixed to the side brackets 201 on both sides. A rotating frame 802 is embedded in the middle of the side suspension plate 807. A rotating shaft 804 is sleeved in the middle of the rotating frame 802. A rotating cylinder 803 is sleeved on the middle surface of the rotating shaft 804. Multiple rotating irregular plates 801 are arranged in a ring on the surface of the rotating cylinder 803. A pushing plate 808 is provided on the top of the rotating irregular plate 801. A flipping plate 805 is provided on the bottom end face of the rotating irregular plate 801. A torsion spring shaft 806 is rotatably connected between the flipping plate 805 and the rotating irregular plate 801. A rectangular opening 1 is provided at the top of the feeding cylinder 8 to connect to the discharge port 1. A rectangular opening 2 is provided at the bottom of the feeding cylinder 8 to connect to the feed rack 101. When the grain The grains enter the feeding cylinder 8 through the first discharge port and the first rectangular opening, and accumulate on the rotating shaped plate near the first rectangular opening. Driven by the weight of the grains, the rotating shaped plate drives the rotating cylinder 301 to rotate along the surface of the rotating shaft 804 until the rotating shaped plate faces the second rectangular opening. At the same time, under the action of the weight of the grains and the force of attraction, the flipping plate 805 is pushed to rotate along the torsion spring shaft 806 until the grains are poured into the feeding rack 101. They enter the second feeding port along the feeding rack 101. During the rotation of the rotating shaped plate, the pushing plate 808 accumulates the guide plate 208. The guide plate 208 is pushed by the force to flip the rotating plate 207 and block the first discharge port, temporarily preventing the grains from flowing into the feeding cylinder 8, thus realizing quantitative feeding.

[0053] Example 3:

[0054] Please see Figure 1 , Figure 5 - Figure 7 As shown, a first air pump 303 is provided at one end of the primary screening box 3 near the rotating drum 301, and a rotary motor 302 connected to the rotating drum 301 is provided at the other end of the primary screening box 3 away from the first air pump 303. Multiple sets of conical nozzles 309 are arrayed inside the cone box 304. Rebound screens 305 are installed on the inner walls of the top of both sides of the cone box 304. A waste slag inlet 306 penetrating the cone box 304 is provided below the rebound screen 305. An inclined screen frame 307 is installed on the inner wall of the bottom of the cone box 304, and a waste slag inlet 308 penetrating the cone box 304 is provided below the inclined screen frame 307. A feed inlet 2 connected to the bottom of the feed rack 101 is provided at the top of the cone box 304, and a discharge outlet 2 facing the primary vibrating screen box 5 is provided at the bottom of the cone box 304.

[0055] The rotary motor 302 drives the rotating drum 301 to rotate within the primary screening box 3 via a coupling and transmission components. Grain particles come into contact with the surface of the rotating drum 301, causing the grain particles, waste husks, and impurities to separate and enter the cone box 304. The first air pump 303 provides airflow to the conical nozzle 309 to pneumatically separate the passing grain particles, waste husks, and impurities. At the same time, the first air pump 303 is connected to waste slag outlet 1 306 and waste slag outlet 2 308 via pipelines to actively extract air from the cone box 304, causing the airflow to guide the lighter waste husks for collection, while the heavier grain particles and impurities enter the vibrating screen box 5 through discharge outlet 2.

[0056] The top of the vibrating screen box 5 is provided with a drop inlet facing the bottom of the cone box 304. The bottom of the vibrating screen box 5 is provided with a vibrating motor 502 that is connected and fixed to the bottom of the support frame 1. Multiple sets of inclined screen plates 503 are installed inside the vibrating screen box 5. The bottom of the vibrating screen box 5 near the inclined material inlet 505 is provided with a discharge port 504 extending to the outside of the support frame 1. The vibrating motor 502 drives the support frame 1 to vibrate inside the vibrating screen box 5 via a coupling, reducer and transmission components. The support frame 1 drives the inclined screen plates 503 to contact the falling grain particles and impurities. Smaller impurities fall along the mesh of the inclined screen plates 503 and collect at the discharge port 504, and are discharged outward along the discharge port 504. The grain particles are intercepted by the inclined screen plates 503 and collected at the inclined material inlet 505, and enter the suction pipe 601 along the inclined material inlet 505.

[0057] The secondary screening box 6 is provided with a suction pipe 601 connected to the inclined material port 505 at one end. The bottom of the inner wall of the secondary screening box 6 at one end is provided with an upward inclined nozzle 602 near the suction pipe 601. The bottom of the secondary screening box 6 is provided with a screw discharge port 603. The suction pipe 601 is connected to the second air pump 702 via a pipeline. The suction pipe 601 draws the collected grain particles into the secondary screening box 6. The second air pump 702 is connected to the upward inclined nozzle 602 and the vertical air jet port 604 via a pipeline. The upward inclined nozzle 602 guides the airflow to blow towards the grain particles entering the secondary screening box 6. It drives the grain particles to fly along the inside of the secondary screening box 6, causing the waste shells remaining on the surface of the grain particles to separate. The grain particles fall into the screw discharge port.

[0058] The slag extraction mechanism 7 includes a slag suction port 701 that penetrates the secondary screening box 6. One end of the slag suction port 701 extends above the vertical jet nozzle 604, and multiple sets of suspended filter elements 703 are installed above the other end of the slag suction port 701. A conical tube 704 is provided below the suspended filter element 703, and a waste bin 705 is provided below the conical tube 704. An exhaust port is provided at the top of the suspended filter element 703, and a second air pump 702 is provided on the side of the exhaust port. The second air pump 702 provides suction to the slag suction port 701 to actively extract the contents of the secondary screening box 6. This causes the separated and floating waste shells in the secondary screening box 6 to enter the slag suction port 701 with the airflow and be intercepted by the suspended filter element 703. The intercepted waste shells fall into the waste bin 705 along the vortex cylinder 803 under their own weight and gravity.

[0059] Combining Embodiments 1, 2, and 3, this system enables comprehensive and efficient monitoring of the grain processing process within the vibrating screen by collecting data during operation and after automatic feeding and diversion. This involves comparing and analyzing the collected data with the vibrating screen's processing flow to obtain evaluation signals of the grain processing. Based on these signals, the system controls the components within the vibrating screen to make adaptive adjustments, compensating for deficiencies during operation, improving the efficiency of grain processing, and reducing the impact of abnormalities in feeding, transportation, and rotational grading. Furthermore, the feeding mechanism 2 assists the primary screening box 3, utilizing the structural linkage between the feeding box 203 and the discharge cylinder 8 to achieve quantitative feeding of grain particles and gravity-fed feeding. This enables metered management of the grain particles, facilitating real-time recording of the proportion of qualified grain particles, waste shells, and impurities separated during the vibrating screen processing, thus helping to understand the quality of different batches of grain particles.

A slag removal mechanism (7) is provided on the end face of the secondary screening box (6) near the vertical air jet (604). The bottom of the feeding box (203) is embedded in the inner wall of the drive box (202), and the top of the drive box (202) is provided with an adjusting cylinder connected to the telescopic arc plate (205). The top of the telescopic arc plate (205) is snapped with an expansion airbag (206). The expansion airbag (206) is provided with multiple sets of telescopic lines (209), and the other end of the telescopic lines (209) is connected to the inner wall of the feeding box (203). The control panel (4) is internally equipped with a processor, a data acquisition module, a self-test feedback module and a signal execution module; The data acquisition module is used to collect the blockage ratio value Qu and the discharge ratio value Wu of the vibrating screen within the time threshold. The value of the blockage ratio Qu reflects the smoothness and speed of the grain particle processing. The larger the value, the more abnormal the grain particle processing in the vibrating screen is. The discharge ratio value Wu represents the ratio of the finished grain particles and the waste shell and impurities discharged from the vibrating screen. The blockage ratio value Qu and the discharge ratio value Wu are sent to the self-test feedback module by the processor. The self-test feedback module obtains the blockage ratio value Qu and the discharge ratio value Wu of the vibrating screen within the time threshold, and then uses the formula... The vibrating screen efficiency Fo is obtained, where a and b are the proportional coefficients of the block ratio value Qu and the output ratio value Wu, respectively, a>b>0. The preset vibrating screen efficiency Yo stored in the processor is immediately retrieved and compared with the vibrating screen efficiency Fo for analysis. If the vibrating screen efficiency Fo ≥ the preset vibrating screen efficiency Yo, it is determined that there is an abnormality in the process of transporting and screening grain particles in the vibrating screen. An adjustment signal is generated and sent to the signal execution module via the processor. After receiving the adjustment signal, the signal execution module immediately controls the first air pump (303) to work. The first air pump (303) is connected to the adjustment cylinder. The adjustment cylinder drives the telescopic arc plate (205) to slide along the inner wall of the bottom of the feeding box (203) to adjust the outward extension length of the telescopic arc plate (205) near the discharge port one, thereby reducing the size of the discharge port one. At the same time, the first air pump (303) is connected to the expansion air bag (206) via the pipeline to reduce the air supply of the expansion air bag (206). After the expansion air bag (206) loses pressure, the telescopic line (209) resets and pulls the expansion air bag (206) to shrink and collapse, causing the space inside the feeding box (203) to increase. If the vibrating screen efficiency Fo is less than the preset vibrating screen efficiency Yo, no signal will be generated.
