Abstract
Description
Technical Field
[0001] This utility model relates to the field of flow velocity measurement technology, and in particular to a particle conveying flow velocity measurement device. Background Technology
[0002] The particle conveying velocity measuring device is a special equipment for detecting the conveying speed of solid particles in pipelines. It is widely used in mining, energy, building materials, chemical and other fields. The device usually consists of sensing components, data processing modules and display terminals. Some high-end models are also equipped with data storage and remote transmission functions.
[0003] The core principle of particle conveying flow rate measurement device is mostly based on the Doppler effect or capacitive sensing technology. The device usually includes a sensor, a signal processor and a display screen. The sensor is installed on the outer wall of the pipe or inserted inside to capture particle motion signals. The processor converts the signals into flow rate data, which is displayed in real time and can be linked to control the device.
[0004] In current technology, some particle conveying velocity measurement devices cannot vibrate the pipeline to make the measurement more accurate. In high humidity, high viscosity or large particle size conveying scenarios, particles are prone to adhere to the pipe wall and accumulate, which not only interferes with the measurement accuracy, but also causes local blockage of the pipeline and affects the operation of the device. Therefore, a particle conveying velocity measurement device is proposed to solve the above problems. Utility Model Content

[0007] A particle conveying flow rate measuring device includes a pipe, an observation platform installed at the top of the pipe, a measuring mechanism installed at the top of the observation platform, and a vibration mechanism installed at the bottom of the observation platform.
[0008] The vibration mechanism includes a motor, a rotating plate is fixedly connected to the drive end of the motor, a follower plate is rotatably connected to the other end of the rotating plate, a linkage plate is rotatably connected to the other end of the follower plate, two limiting columns are fixedly connected to the bottom of the observation platform, springs are sleeved on the outside of the two limiting columns, a connecting plate is slidably connected to the outside of the limiting columns, a fixed column is fixedly connected to the bottom of the connecting plate, a cylinder is fixedly connected to the bottom of the fixed column, and a sealing component is provided inside the pipe.

[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, when particles pass through the pipe, they are prone to blockage due to multiple particles passing through at the same time. The motor is started, which drives the rotating plate to rotate, causing the follower plate to rotate, and then the linkage plate to slide on the limiting column. The limiting column moves up and down, which drives the connecting plate to move up and down through the spring. The connecting plate drives the fixed column to move up and down through the cylinder, which hammers and vibrates the pipe, making the particles pass through more smoothly and ensuring accurate detection.
[0025] 2. In this utility model, rotating the sliding plate drives the rotating ring to rotate, which in turn causes multiple connecting rods to rotate. The connecting rods drive the rotating block to rotate. Since the bottom of the rotating column at one end of the rotating block is fixed to the top of the pipe, the rotating block will rotate around the rotating column, causing multiple rotating blocks to rotate or merge, thereby preventing particles from flowing out when not being detected.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figure 1 , Figure 3 and Figure 4An embodiment of this utility model is provided: a particle conveying flow rate measuring device, including a pipe 1 for conveying particle materials, an observation platform 2 installed on the top of the pipe 1, a measuring mechanism 4 installed on the top of the observation platform 2, the measuring mechanism 4 for accurately measuring the conveying flow rate of particles in the pipe 1, and a vibration mechanism 5 installed at the bottom of the observation platform 2 for generating vibration to prevent particles from accumulating and clogging in the pipe 1 and to ensure measurement accuracy.
[0035] The vibration mechanism 5 includes a motor 51, which provides power. A rotating plate 52 is fixedly connected to the drive end of the motor 51, driving the rotating plate 52 to rotate. A follower plate 53 is rotatably connected to the other end of the rotating plate 52, causing the follower plate 53 to move. A linkage plate 55 is rotatably connected to the other end of the follower plate 53, causing the linkage plate 55 to move up and down. Two limiting posts 54 are fixedly connected to the bottom of the observation platform 2. The limiting posts 54 are used to limit the movement direction of the linkage plate 55, ensuring its vertical up and down movement. Springs 56 are sleeved on the outside of the two limiting posts 54, and the springs 56 produce elastic deformation. A connecting plate 57 is slidably connected to the outside of the limiting posts 54, and the connecting plate 57 can slide along the limiting posts 54. The column 54 slides, and the bottom of the connecting plate 57 is fixedly connected to the fixed column 58. The fixed column 58 connects to the connecting plate 57 to transmit vibration force. The bottom of the fixed column 58 is fixedly connected to the cylinder 59. The cylinder 59 contacts the pipe 1 and transmits the vibration force to the pipe 1 to prevent particle accumulation. The bottom of the observation platform 2 is fixedly connected to the fixed plate 6, which provides support. The motor 51 is externally fixedly connected to the outer wall of the fixed plate 6 to make the motor 51 securely installed. One end of the spring 56 is fixedly connected to the top of the connecting plate 57, and the other end of the spring 56 is fixedly connected to the bottom of the linkage plate 55. When the linkage plate 55 moves up and down, it compresses or stretches the spring 56. The elastic force of the spring 56 causes the connecting plate 57 and the cylinder 59 to vibrate continuously.
[0036] Reference Figure 1 and Figure 2 The pipe 1 is equipped with a sealing component 3, which includes a rotating ring 31. A sliding plate 32 is fixedly connected to the top of the rotating ring 31, which facilitates the rotation of the rotating ring 31. Multiple connecting rods 34 are rotatably connected to the outside of the rotating ring 31. The rotation of the rotating ring 31 causes the connecting rods 34 to swing. The other end of each of the multiple connecting rods 34 is rotatably connected to a rotating block 35. The swing of the connecting rods 34 causes the rotating block 35 to rotate. A rotating column 36 is rotatably connected to one end of the rotating block 35, which provides a fulcrum for the rotation of the rotating block 35. Multiple limiting columns 33 are fixedly connected to the top of the observation platform 2. The limiting columns 33 restrict the movement trajectory of the rotating ring 31 to ensure its stable rotation. The outside of the limiting columns 33 is slidably connected to the inside of the rotating ring 31, so that the rotating ring 31 rotates smoothly along the limiting columns 33. The bottom of the rotating column 36 is fixedly connected to the inside of the observation platform 2 to ensure that the rotating column 36 is installed securely.
[0037] Reference Figure 1 and Figure 5 The measuring mechanism 4 includes a display screen 41, which is used to intuitively display and show the measurement data of the particle conveying flow rate for easy reading. One end of the display screen 41 is fixedly connected to a controller 42, which is used to receive and process signals. The other end of the controller 42 is fixedly connected to a force detector 43, which is used to detect the impact force generated when the particles flow and convert the mechanical signal into an electrical signal and transmit it to the controller 42. The bottom of the force detector 43 is fixedly connected to a detection head 44, which directly contacts the flowing particles to sense and transmit the impact force. The bottom of the display screen 41 is fixedly connected to the top of the observation platform 2 to ensure that the display screen 41 is stably installed and easy to observe. The bottom of the controller 42 is fixedly connected to the top of the observation platform 2 to ensure that the controller 42 is installed stably. The bottom of the force detector 43 is fixedly connected to the top of the observation platform 2 to ensure that the position of the force detector 43 is fixed and to ensure detection accuracy. The bottom of the observation platform 2 is fixedly connected to multiple casters 7, which facilitate the flexible movement of the entire device and adapt to different measurement scenarios.
[0038] Working principle: Rotating the sliding plate 32 drives the rotating ring 31, which in turn drives multiple connecting rods 34 to rotate. The rotating rods 34 in turn drive the rotating block 35 to rotate. One end of the rotating block 35 has a rotating column 36. The bottom of the rotating column 36 is fixed to the top of the pipe 1, causing the rotating block 35 to rotate around the rotating column 36. This allows multiple rotating blocks 35 to rotate or merge, thereby preventing particles from flowing out when not being detected.
[0039] Slide the observation platform 2 above the area to be inspected, place the inspection head 44 into the pipe 1 for inspection, and transmit the inspection data to the controller 42 for analysis through the force detector 43, and display it intuitively on the display screen 41.
[0040] When particles pass through pipe 1, multiple particles may pass through simultaneously, causing blockage. Motor 51 is started, which drives rotating plate 52 to rotate. Rotating plate 52 drives follower plate 53 to rotate. Follower plate 53 drives linkage plate 55 to slide on limiting post 54. Limiting post 54 moves up and down, which drives connecting plate 57 to move up and down through spring 56. The movement of connecting plate 57 drives fixed post 58 to move up and down through cylinder 59, which hammers and vibrates pipe 1, making the particles pass through pipe 1 more smoothly and making the detection more accurate.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
