Abstract
Description
Technical Field
[0001] This utility model relates to the field of particle and powder conveying control technology, and more specifically, to a material thickness detection device for controlling the vibrator of a silo. Background Technology
[0002] During the processes of conveying, rolling, mixing, and proportioning, granular powders need to pass through multiple silos, and multiple parallel silos exist in a single process. Due to the influence of material moisture, composition, and production environment, materials often accumulate and clump on the inner walls of the silos, resulting in non-discharge. To ensure uniform and normal material discharge from the silos, vibrators are generally installed on the silo walls.
[0003] The original design of the silo vibrator was for uniform intermittent operation. However, after starting production, it operated continuously, frequently causing cracks in the base. This not only easily cracked and tore open the silo welds, but also led to a thick accumulation of material on the conveyor belt due to prolonged vibration, affecting the uniformity of material transport. In particular, with a belt conveyor installed at the bottom of the silo for material transport, excessive material accumulation on the conveyor belt could cause slippage, impacting its transport efficiency.
[0004] Therefore, it is necessary to propose a material thickness detection device for controlling the vibrator of the silo to ensure uniform material conveying. Utility Model Content
[0005] This invention provides a material thickness detection device for controlling the vibrator of a hopper, in order to solve the problem of uneven material discharge caused by the inability to adjust the working frequency of the vibrator on the existing hopper in real time.
[0006] According to one aspect of the present invention, a material thickness detection device for controlling a hopper vibrator is provided, which is installed at the hopper outlet on the upper part of a belt conveyor. The material thickness detection device includes a mounting base and a thickness detection rod. The mounting base is installed on both sides of the hopper. The mounting base includes a vertical plate and a base plate. The vertical plate is welded to the base plate in an L-shape. A sensor is provided on the vertical plate. The thickness detection rod includes a sensing block, a connecting rod, and a mounting shaft. The mounting shaft is mounted on the mounting base. A signal detection plate is installed at the end of the mounting shaft. The signal detection plate is arranged opposite to the sensor. The connecting rod is installed in the middle of the mounting shaft. The sensing block is installed at the end of the connecting rod and is located on the upper part of the belt conveyor.
[0007] Based on the above scheme, preferably, the mounting base includes a support plate, the support plate is arranged perpendicularly to the base plate, the mounting shaft is rotatably mounted on the support plate, the free end of the mounting shaft is equipped with the signal detection plate, and the signal detection plate rotates relative to the upright plate around the mounting shaft.
[0008] In a preferred embodiment of the above scheme, a control board is also installed at the bottom of the hopper, and the control board is arranged opposite to the connecting rod.
[0009] Based on the above scheme, the preferred embodiment is that the discharge port of the hopper is set in an arc shape in the transport direction of the belt conveyor.
[0010] Based on the above scheme, a preferred embodiment is provided on the hopper, and the vibrator and the sensor are respectively connected to the controller.
[0011] This utility model discloses a material thickness detection device for controlling a hopper vibrator. A mounting base is installed on the hopper, and a sensing block rotating around a mounting shaft is mounted on the mounting base. When there is too much material at the bottom, the sensing block is subjected to a force that causes it to rotate around the mounting shaft. This causes a signal detection plate on the free end of the mounting shaft to rotate relative to a sensor on the vertical plate. This allows for signal connection or disconnection, obtaining the thickness of the material at the bottom, thereby controlling the vibrator's operating frequency, controlling the amount of material discharged, and ensuring the uniformity of material conveying on the belt conveyor.
[0012] When the material hopper is blocked and the material flow is obstructed, the material thickness detection device immediately sends a control signal to start the vibrator when it detects a break in the material flow on the conveyor belt or a thinning of the material thickness. This vibrates the material down, ensuring a continuous supply of materials. After the device is put into use, it can promptly detect breaks in the material flow from the hopper and start the vibrator to ensure a continuous supply of production materials. This avoids the problem of the original design where the vibrator would break the hopper due to prolonged operation. At the same time, the intermittent operation of the vibrator saves energy and reduces the consumption of spare parts. Attached Figure Description

[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.
[0025] Please see Figure 1 and combined Figure 2 As shown, the material thickness detection device for controlling the vibrator of the hopper of this utility model is installed at the discharge port of the hopper 4 on the upper part of the belt conveyor 3. It is used to sense the thickness of the material on the belt conveyor 3 in order to control the working frequency of the vibrator 5 on the hopper 4, so as to adjust the thickness of the material on the conveyor and ensure the uniformity of material conveying.
[0026] Specifically, the material thickness detection device of this utility model includes a mounting base 1 and a thickness detection rod 2. The mounting base 1 is installed on both sides of the hopper 4, and the thickness detection rod 2 is rotatably mounted on the mounting base 1.
[0027] For a more detailed explanation of the technical solution of this utility model, please refer to [link / reference needed]. Figure 2 As shown, the mounting base 1 of this utility model includes a vertical plate 11, a base plate 12 and a support plate 14. The vertical plate 11 is welded to the base plate 12 in an L-shape, and the support plate 14 is welded to the base plate 12 and is perpendicular to the base plate 12.
[0028] The thickness detection rod 2 includes a sensing block 21, a connecting rod 22, and a mounting shaft 23. The sensing block 21 is mounted on the mounting base 1 via the connecting rod 22. The two ends of the mounting shaft 23 are rotatably mounted on the support plate 14. The sensing block 21 is located above the belt conveyor 3, and a signal detection plate 24 is mounted on one end of the mounting shaft 23. The signal detection plate 24 is positioned opposite to the sensor 13 on the vertical plate 11. When the material thickness on the belt is normal, the material causes the sensing block 21 to lift upwards, and the mounting shaft 23 rotates, causing the signal detection plate 24 to rotate away from the sensor 13, increasing the distance between the signal detection plate 24 and the sensor 13. When the material thickness on the belt decreases or there is a break in the material, the sensing block 21 droops due to gravity, and the mounting shaft 23 rotates in the opposite direction, causing the signal detection plate 24 to rotate relative to the sensor 13, decreasing the distance between the signal detection plate 24 and the sensor 13.
[0029] The hopper 4 is also equipped with a vibrator 5, and the vibrator 5 and the sensor 13 are respectively connected to the controller. The vibrator 5 involved in this utility model is the ZSGB-1236 model from Xinxiang Hongda Vibration Equipment Co., Ltd., and the sensor 13 is the 872C-N20NP30-E2 model from AB Company; the controller is the S7-200SMART 288-1ST20 model from Siemens.
[0030] In use, when too much material accumulates on the belt conveyor 3, the sensing block 21 rotates the mounting shaft 23 under the action of the material. At this time, the position of the signal detection board 24 relative to the sensor 13 is larger, and the data acquired by the sensor 13 is sent to the controller. The controller controls the vibrator 5 to stop working. Conversely, when too little material accumulates on the belt conveyor 3, the mounting shaft 23 rotates under the action of the sensing block 21's own gravity without the action of material resistance. At this time, the position of the signal detection board 24 relative to the sensor 13 becomes smaller, and the data acquired by the sensor 13 is sent to the controller. The controller controls the vibrator 5 to work, increasing the output of material.
[0031] Furthermore, the present invention also includes a control board installed at the bottom of the hopper 4, the control board being positioned opposite to the connecting rod 22, and the discharge port of the hopper 4 being arc-shaped in the transport direction of the belt conveyor 3.
[0032] The material thickness detection device for controlling the vibrator of the hopper of this utility model is achieved by setting a mounting base 1 on the hopper 4 and installing a sensing block 21 that rotates around the mounting shaft 23 on the mounting base 1. When there is too much material at the bottom, the sensing block 21 will be subjected to force and rotate around the mounting shaft 23, thereby driving the signal detection plate 24 on the free end of the mounting shaft 23 to rotate relative to the sensor 13 on the upright plate 11. In this way, the signal can be turned on or off to obtain the thickness of the material at the bottom, thereby controlling the working frequency of the vibrator 5, controlling the amount of material discharged, and ensuring the uniformity of material conveying on the belt conveyor 3.
[0033] When the material hopper is blocked and the material flow is obstructed, the material thickness detection device immediately sends a control signal to start the vibrator 5 when it detects a break in the material flow on the conveyor belt or a thinning of the material thickness. This vibrates the material down, ensuring the continuity of material flow. After the device is put into use, it can promptly detect breaks in the material flow from the hopper and start the vibrator 5 to ensure a continuous supply of production materials. This avoids the original design where the vibrator 5 would crack the hopper 4 due to prolonged operation. At the same time, the intermittent operation of the vibrator 5 saves energy and reduces the consumption of spare parts.
[0034] Finally, the method described in this application is merely a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
