AI Technical Summary
Existing level gauges cannot accurately and continuously measure the material level in the dust collector hopper across the entire height range, making it difficult for operators to judge changes in the amount of ash in the hopper in a timely and accurate manner, which can easily lead to extreme situations such as material bridging, bridging, or leakage.
A dynamic continuous material position measuring device is adopted. By combining a probe with a vibration source and a vibration sensor, the vibration of the probe in the material is monitored in real time. The vibration energy is analyzed by a controller to measure the material height.
It enables accurate, dynamic, and continuous measurement of the material height in the dust collector hopper, improving operational safety and ensuring the accuracy of real-time monitoring and operational judgment regarding material changes in the hopper.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of material height measurement technology in containers, specifically a dynamic continuous material position measurement device. Background Technology
[0002] Commonly used level gauges on the market include: capacitive, radio frequency admittance, weighted, weighing, ultrasonic / radar, patch, laser, passive nuclear, and active nuclear level gauges. Different level gauges have their own advantages and disadvantages, but they all share a common problem: they cannot accurately and continuously measure the level of materials in the dust collector hopper across the entire height range. Because various hopper level gauges cannot monitor the hopper level in real time, operators find it difficult to grasp the actual amount of ash or changes in the ash level. When extreme conditions such as material accumulation, bridging, or leakage occur inside the hopper, leading to inaccurate level detection, timely and accurate operational judgments cannot be made. Utility Model Content
[0003] To address the aforementioned issues, this utility model provides a dynamic continuous material position measuring device, which can accurately and continuously measure the material level within the entire height range of the dust collector hopper, thus ensuring the safe operation of the dust collector hopper.
[0004] The present invention adopts the following technical solution: a dynamic continuous material position measuring device, comprising a probe, the detection end of the probe being inserted into the dust collector ash hopper container, an mounting block being mounted on the outer end of the probe, and a vibration source for maintaining the vibration of the probe and a vibration element for collecting the vibration amount of the probe being mounted on the mounting block, wherein the wiring terminals of the vibration source and the vibration element are respectively connected to the controller via cables.
[0005] Furthermore, an embedded part is welded to the wall of the dust collector hopper container, and the probe part located outside the dust collector hopper container is connected to the mounting part through a flexible connector, and the mounting part is connected to the embedded part;
[0006] Furthermore, the flexible connector is made of plastic; the mounting component is a tubular structure and has an outwardly extending protrusion that is connected to the embedded component.
[0007] Furthermore, the vibration source is a vibration generator, and the vibrating component is a vibration sensor or an acceleration sensor;
[0008] Furthermore, the probe is a hollow or solid structure, and the probe is made of metal.
[0009] Furthermore, the length of the probe portion that penetrates into the dust collector hopper container is 0.1m to 1m;
[0010] Furthermore, the probe is located 1m to 1.5m above the bottom of the dust collector hopper container.
[0011] The beneficial effects of this utility model are that the detection end of the probe is directly inserted into the dust collector ash hopper container and comes into direct contact with the material inside the container. By continuously measuring the change in the vibration of the probe, the height of the material inside the container can be accurately obtained, which makes it easier for operators to grasp the actual amount or change in ash level in the ash hopper container, improves safety, and has good economic value. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation
[0013] like Figure 1 As shown, the present invention provides a dynamic continuous material position measuring device, comprising a probe 1, the detection end of which is inserted into a dust collector hopper container 2, and an mounting block 3 mounted on the outer end of the probe 1. The mounting block 3 is equipped with a vibration source 4 for maintaining the vibration of the probe 1 and a vibration element 5 for collecting the vibration amount of the probe 1. The wiring terminals of the vibration source 4 and the vibration element 5 are respectively connected to a controller 6 via cables. The controller 6 can control the vibration source 4 to vibrate stably and process the collected vibration data.
[0014] An embedded part 7 is welded to the wall of the dust collector hopper container 2. The probe 1 part located outside the dust collector hopper container 2 is connected to the mounting part 9 through a flexible connector 8. The mounting part 9 is connected to the embedded part 7. The flexible connector 8 is made of plastic. The mounting part 9 is a tubular structure and has an outwardly extending protrusion 10, which is connected to the embedded part 7.
[0015] The vibration source 4 uses a vibration generator, and the vibration component 5 uses a vibration sensor or an acceleration sensor.
[0016] The probe 1 is a hollow or solid structure, and the material of the probe 1 is metal, such as 304 stainless steel or 316L stainless steel. The length of the part of the probe 1 that penetrates into the dust collector hopper container 2 is 0.1m to 1m. The probe 1 is located 1m to 1.5m above the bottom of the dust collector hopper container 2.
[0017] In this invention, the measuring device is installed at a height of 1.5m above the bottom of the dust collector hopper container 2 for easy maintenance. The detection end of the probe 1 is inserted into the dust collector hopper container 2 and comes into direct contact with the material 11 inside the container, making the measurement more accurate. The vibration source 4 can maintain the continuous and stable vibration of the probe 1. When the material inside the dust collector hopper container 2 exceeds the height of the probe 1, the material will cover the probe 1. As the volume of the material increases or decreases, the amount of vibration on the probe 1 will change. That is, when the material inside the dust collector hopper container 2 is at a high ash level, the amount of vibration on the probe 1 will decrease. When the material inside the dust collector hopper container 2 is at a low ash level, the amount of vibration on the probe 1 will increase or remain unchanged. The vibration sensor sends the changing amount of vibration to the existing controller 6 (such as DCS controller 6). The existing vibration energy analysis method used in the controller 6 can measure the position of the material, thereby determining the state of the material inside the dust collector hopper container 2, and thus dynamically and continuously obtaining the height change of the material.
