Description

Technical Field

[0001] The invention relates to the technical field of hopper flow regulation, and in particular to a visual hopper flow regulation device. Background Art

[0002] The hopper flow control device is used to control the rate at which solid materials flow out of the hopper, and is widely used in the chemical, food processing, pharmaceutical and other industries. At present, some simple mechanical control devices may be difficult to meet high-precision requirements, especially in small-batch production environments that require precise measurement. And for materials with uneven particle sizes or easy to agglomerate, it is easy to cause blockage at the hopper outlet, affecting normal operation. The degree of automation is not high. Although there are many products with certain automation functions on the market, there are still many occasions where the more traditional manual operation method is used, which cannot meet the efficiency and safety requirements of modern production lines. Some adjustment systems that are not well designed may have large energy consumption problems, which will significantly increase operating costs in long-term operation.

[0003] For example, the Chinese patent publication number CN208666058U discloses a flow regulating device for a pouring hopper, including a fixed pipe sleeve, the interior of the fixed pipe sleeve is provided with a pouring hopper fixedly connected, the pouring hopper includes an upper hopper and a lower hopper, both sides of the upper hopper are provided with flow regulating devices, and the lower side of the lower hopper is provided with a vibration mechanism. The utility model can realize the function of flow regulation of the pouring hopper, reduce the difficulty of the staff's work, and at the same time avoid the phenomenon of concrete silting up in the lower hopper to cause blockage.

[0004] The existing technology has the following problems:

[0005] The injection material is usually stirred manually during use, but the force used is not enough and the stirring is uneven, resulting in insufficient stirring. During the injection process, sometimes a large amount of supply is required, and sometimes a small amount is required. However, the flow rate of existing devices is usually fixed, which is not convenient to use. In the industrial production process, material flow control is crucial to ensure production efficiency and product quality. Traditional flow control devices often lack real-time monitoring and feedback functions and cannot meet the precise requirements of modern production. Summary of the invention

[0054] See attached Figure 1-2 , the embodiment of the present application provides a visual hopper flow regulating device, comprising:

[0055] The hopper 1 has a discharge port 11 at the bottom and a feed port 12 at the top, and the bottom is a conical structure to facilitate the outflow of materials and prevent blockage;

[0056] The stirring and anti-wall-sticking mechanism 2 is arranged inside the hopper 1 and is used to stir the material in the hopper 1 and prevent the material from sticking to the wall and accumulating;

[0057] A flow regulating mechanism 3 is provided on the hopper 1 and is used to regulate the flow of materials in the hopper 1;

[0058] The monitoring mechanism 4 is arranged in the hopper 1, distributed on the top wall of the hopper 1, the inner side wall of the hopper 1 and the discharge port 11 of the hopper 1, and monitors the flow of the material in the hopper 1, the material level and the material flow rate;

[0059] The visual control mechanism 5 is arranged outside the hopper 1 and is electrically connected to the stirring and anti-wall-hanging mechanism 2, the flow regulating mechanism 3, and the monitoring mechanism 4, and is used to control the operation of the stirring and anti-wall-hanging mechanism 2 and the flow regulating mechanism 3, and to receive signals from the monitoring mechanism 4.

[0060] The stirring anti-wall mechanism 2 comprises:

[0061] A stirring motor 21 is disposed at the top of the hopper 1 and is fixedly connected to the top of the hopper 1. An output shaft of the stirring motor 21 passes through the top wall of the hopper 1 and extends into the hopper 1, and is rotatably connected to the top wall of the hopper 1.

[0062] A stirring shaft 22 is disposed in the hopper 1, fixedly connected to the output shaft of the stirring motor 21, vertically disposed in the hopper 1, and in the same straight line as the central axis of the hopper 1;

[0063] A stirring blade 23 is disposed on the stirring shaft 22, is disposed perpendicular to the stirring shaft 22, is provided with a plurality of stirring blades, is evenly spaced on the stirring shaft 22, and is fixedly connected to the stirring shaft 22;

[0064] A connecting rod 24 is disposed on the stirring shaft 22, is disposed perpendicular to the stirring shaft 22, is provided with two connecting rods, is disposed oppositely on both sides of the stirring shaft 22, and is fixedly connected to the stirring shaft 22;

[0065] The scraper 25 is vertically arranged in the hopper 1 and abuts against the inner wall of the hopper 1 . The scraper 25 is fixedly connected to the connecting rod 24 , and a pad is arranged at one end thereof abutting against the inner wall of the hopper 1 .

[0066] Specifically, when in use, the stirring motor 21 is first started, and the stirring motor 21 starts to rotate, and its output shaft rotates accordingly. Since the stirring shaft 22 is fixedly connected to the output shaft of the stirring motor 21, the stirring shaft 22 will also rotate accordingly. As the stirring shaft 22 rotates, the multiple stirring blades 23 installed thereon also begin to rotate around the center line of the stirring shaft 22. These blades can effectively flip, shear and mix the materials in the hopper. At the same time, the scrapers 25 fixed on both sides of the stirring shaft 22 by the connecting rod 24 will also move along the circumference of the inside of the hopper. The scraper 25 is in close contact with or close to the inner wall of the hopper 1, so that the materials that are about to adhere or have adhered to the inner wall can be scraped back into the main body of the material during each rotation process, thereby avoiding the formation of a difficult-to-clean accumulation layer on the side wall of the container. The pad located at the end of the scraper directly contacting the inner wall of the hopper can reduce the possible wear and tear on the hopper wall surface, and also increase the scraping efficiency. The appropriate material selection can allow the pad to more effectively remove the attachments without damaging the container itself. The entire system continues to operate until the desired mixing degree is reached. During this period, the stirring blades 23 continuously promote material exchange to ensure uniform distribution of components; while the scraper 25 ensures the cleanliness of the inner wall, reduces the amount of residual materials, and improves production efficiency and final product quality.

[0067] See also Figure 2 As shown, the flow regulating mechanism 3 includes:

[0068] A fixed plate 31 is arranged outside the hopper 1, located at the middle and lower end of the hopper 1, and arranged parallel to the outer wall of the hopper 1. It is fixedly connected to the outer wall of the hopper through a horizontally arranged connecting rod, and the two ends of the connecting rod are respectively fixedly connected to the fixed plate 31 and the outside of the hopper 1;

[0069] The push plate 32 is arranged outside the hopper 1, between the outer wall of the hopper 1 and the fixing plate 31, and parallel to the outer wall of the hopper 1 and the fixing plate 31;

[0070] A limiting rod 33 is arranged outside the hopper 1 and is vertically arranged with the hopper 1, one end of which is fixedly connected with the hopper 1, and the other end of which penetrates the push plate 32 and is slidably connected with the push plate 32;

[0071] A rotating threaded rod 34 is disposed outside the hopper 1 and is vertically disposed with respect to the hopper 1, one end of which is rotatably connected with the outer wall of the hopper 1, and the other end of which penetrates through the push plate 32 and is threadedly connected with the push plate 32;

[0072] The rotary motor 35 is disposed on the fixed plate 31 and fixedly connected to the fixed plate 31. The output end of the rotary motor 35 passes through the fixed plate 31 and is rotationally connected to the fixed plate 31 and is fixedly connected to the rotating threaded rod 34, so as to drive the rotating threaded rod 34 to rotate.

[0073] The intercepting plate 36 is disposed through the side wall of the hopper 1 and is slidably connected to the side wall of the hopper 1 . One end of the intercepting plate 36 is disposed in the hopper 1 , and the other end is fixedly connected to the pushing plate 32 .

[0074] The flow regulating mechanism 3 also includes a guide plate 37, which is arranged in the hopper 1, one end of which is arranged at the discharge port of the hopper 1 and is hinged to the inner wall of the hopper 1, and the other end is in contact with one end of the intercepting plate 36 located in the hopper 1, and a slide groove is provided on the side of the guide plate 37 that is in contact with the intercepting plate 36, and an arc-shaped slider is provided at the end of the intercepting plate 36, one end of the arc-shaped slider is fixedly connected to the intercepting plate 36, and the other end is arranged in the slide groove and is slidably connected to the guide plate 37.

[0075] The flow regulating mechanism 3 is provided with two groups, which are respectively arranged on both sides of the hopper 1.

[0076] It should be noted that when the rotating motor 35 is not started, the intercepting plate 36 is maintained at a preset position, which determines the initial flow rate of the material through the outlet of the hopper 1. When the material flow rate needs to be adjusted, the rotating motor 35 is started by the controller. The rotating motor 35 drives the rotating threaded rod 34 fixed to its output end to rotate. Since the rotating threaded rod 34 is threadedly connected to the push plate 32, when the rotating threaded rod 34 rotates, it will cause the push plate 32 to move along the direction of the limit rod 33. Here, the limit rod 33 ensures that the push plate 32 can only move along a straight path. While the push plate 32 moves, because one end of it is fixedly connected to the intercepting plate 36, it will simultaneously pull or push the intercepting plate 36 to slide in the side wall of the hopper 1, thereby changing the position of the intercepting plate 36 relative to the outlet of the hopper. The change in the position of the intercepting plate 36 directly affects the size of the opening through which the material flows out of the hopper, thereby achieving effective regulation of the outflow amount or speed of the material. If the flow rate needs to be increased, the rotating motor 35 drives the rotating threaded rod 34 to rotate in one direction so that the push plate 32 pulls the intercepting plate 36 to move and expand the discharge port. On the contrary, if the flow rate needs to be reduced, the rotating motor 35 rotates the rotating threaded rod 34 in the opposite direction, prompting the push plate 32 to push the intercepting plate 36 to move and reduce the discharge port. Once the required flow setting is reached, the rotating motor 35 stops working, and the entire system remains in operation at this new flow state. This structural design allows the user to accurately control the speed or total amount of material flow according to actual needs. And by setting the guide plate 37, the material can be better allowed to flow out through the guide plate 37 to prevent blockage. Since an arc-shaped slider is provided at one end of the intercepting plate 36, and the slider is located in the slide groove of the guide plate 37, the intercepting plate 36 will drive the guide plate 37 to move together during the movement.

[0077] See also Figure 1-2 As shown, the monitoring mechanism 4 includes:

[0078] A camera 41 is disposed in the hopper 1 and fixedly connected to the top wall of the hopper 1 to monitor the flow of materials in the hopper 1;

[0079] There are two material level sensors 42, which are respectively arranged at the highest material point and the lowest material point in the hopper 1 to monitor the material height inside the hopper 1 to prevent overloading or lack of material;

[0080] The flow sensor 43 is disposed in the hopper 1 and at the discharge port of the hopper 1 to detect the flow rate of the outflowing material in real time.

[0081] The visual control mechanism 5 comprises:

[0082] A visual display screen is arranged outside the hopper 1 and is fixedly connected to the outer wall of the hopper 1;

[0083] The controller is arranged outside the hopper 1, fixedly connected to the outer wall of the hopper 1, and electrically connected to the stirring motor 21, the rotating motor 35, the camera 41, the material level sensor 42 and the flow sensor 43. It receives the monitoring image of the camera and transmits it to the visual display screen, so that the situation in the hopper can be viewed in real time, receives the signals of the material level sensor 42 and the flow sensor 43, and controls the start and stop of the stirring motor 21 and the rotating motor 35.

[0084] Specifically, the camera 41 installed at the top of the hopper continuously monitors the flow of materials and transmits the video stream to the controller. The operator can view the internal conditions of the hopper in real time through the visual display. The two level sensors 42 located at the highest and lowest points in the hopper monitor the height of the materials respectively. When the material height exceeds the set upper limit, the system will issue an alarm or take measures to prevent overloading; when the material is lower than the set lower limit, it will remind to replenish the material to avoid material shortage. The flow sensor 43 set at the discharge port 11 detects the actual flow of the outflowing material in real time and sends the data to the controller. The controller receives data from the camera, the level sensor and the flow sensor, and analyzes and processes the information. If the flow sensor shows that the actual flow does not match the preset value, the controller will activate the rotary motor, move the push plate 32 by rotating the threaded rod 34, and then change the position of the intercepting plate 36 to adjust the material flow. According to the feedback of the level sensor 42, if it is found that there is too much or too little material, the feeding can be suspended or replenished to ensure the continuity and safety of production. Through the visual display screen, operators can observe all relevant real-time data (such as current flow, material level, etc.), and can manually adjust parameters or directly intervene in the control system as needed, such as manually controlling the speed of the rotating motor to fine-tune the material flow.

[0085] To further optimize the above technical solution, the controller is based on a PLC programmable logic controller, which receives sensor signals, performs data processing and flow control, and integrates a PID control algorithm to achieve precise flow regulation.

[0086] The flow control method of the controller is as follows:

[0087] The flow sensor 43 continuously detects the actual rate at which the material flows through the pipeline and transmits the signal to the PLC;

[0088] Material level monitoring, the material level sensor 42 monitors the material level in the hopper and also sends data to the PLC;

[0089] The controller adjusts the control output according to the error between the set value and the actual measured value;

[0090] Accumulating the effects of all past errors helps eliminate static errors;

[0091] Predict future trends and respond quickly accordingly to reduce system shocks;

[0092] The initial settings need to be adjusted according to the specific application, usually using self-tuning methods or empirical methods for optimization;

[0093] PLC generates control instructions based on PID calculation results and adjusts material flow by changing the position of the interceptor plate;

[0094] The current flow rate, material level and other related parameters are displayed in real time on the visual display screen;

[0095] When an abnormal situation occurs, such as flow rate exceeding the preset range, an alarm is automatically triggered to alert the operator.

[0096] Working principle: The material enters the hopper through the feed port 12, and the material level sensor 42 monitors the height of the material in the hopper in real time; the flow sensor 43 monitors the material flow rate at the discharge port and transmits the data to the control system; the control system automatically adjusts the opening of the flow control valve according to the set flow target to ensure that the material flows out at a stable flow rate; all data are displayed in real time through a visual interface, and the operator can view and adjust parameters at any time.

[0097] The present application provides a visual hopper flow regulating device, which realizes a combination of a visual means camera and a visual display screen by setting a visual display screen and a camera and other structures, thereby improving production efficiency while ensuring product quality and reducing errors caused by human factors to a certain extent; a shut-off plate is set, and the position of the shut-off plate in the hopper is adjusted by starting a rotating motor and rotating a threaded rod, thereby controlling the flow of materials, and combined with the setting of a monitoring mechanism, precise control of the flow is achieved, and waste in the production process is reduced by precisely controlling the material flow; a stirring and anti-wall hanging mechanism is set to stir the material and prevent the material from accumulating on the inner wall of the hopper, thereby enhancing safety, and the stirring action, material level monitoring and flow control effectively avoid material overload and blockage; it is easy to operate, and the visual interface enables operators to easily grasp the operating status of the equipment and respond quickly to abnormal situations.
