Abstract
Description
Technical Field
[0001] This utility model belongs to the field of crusher technology, specifically relating to a device for alerting abnormal material feeding in a crusher. Background Technology
[0002] The raw material for the acetylene workshop is calcium carbide delivered by a calcium carbide company. The calcium carbide supplied by the company has a particle size of approximately 300.00 mm, while the calcium carbide used in the acetylene workshop is required to have a particle size of 30.00–80.00 mm. In this process, a crusher is needed to break the approximately 300.00 mm calcium carbide into calcium carbide with a particle size of 30.00–80.00 mm.
[0003] A utility model patent with patent authorization announcement number CN212943446U discloses a crusher for crushing calcium carbide, including a main support and a cleaning device. An operating table is fixedly connected to the upper end of the main support. The cleaning device is provided at the feed inlet of the operating table. The cleaning device includes a first U-shaped plate. The side of the first U-shaped plate near the feed inlet is fixedly connected to the operating table. A second cylindrical pin is inserted into both sides of the first U-shaped plate. A vibrating groove block is fixedly connected to the side of the two second cylindrical pins that are close to each other. A motor is provided inside the vibrating groove block. A slider is fixedly connected to both sides of the motor. A first cylindrical pin is inserted into the inside of both sliders.
[0004] However, existing crushers also have certain drawbacks. During the crushing process, calcium carbide frequently gets stuck in the crushing chamber (5 times / day), which cannot be detected on-site in time. This results in a large amount of calcium carbide (about 10 tons per 10 minutes) accumulating and weathering on-site. Operators need to spend about 3 hours a day cleaning it, causing high labor and material costs. Summary of the Invention
[0005] The purpose of this utility model is to provide a device for alerting abnormal material feeding in a crusher, which solves the problem that in existing crushers, calcium carbide frequently gets stuck in the crushing chamber during the crushing process (5 times / day), which cannot be detected on-site in time, resulting in a large amount of calcium carbide (about 10t per 10 minutes) accumulating and weathering on-site. Operators need to spend about 3 hours a day cleaning it, resulting in high labor and material costs.
[0006] To achieve the above objectives, this utility model provides a device for alerting abnormal material feeding in a crusher, comprising a computer disposed on the left side of a production frame, a calcium carbide body disposed on the upper horizontal part of the production frame, a crusher disposed on the middle horizontal part of the production frame, a crushing motor disposed on the right side of the crusher, a signal transmission line disposed between the crushing motor and the computer, the signal transmission line passing through the production frame, and a conveyor belt disposed on the lower horizontal part of the production frame, on which crushed calcium carbide is disposed.
[0007] The principle of this utility model is as follows: When the crusher (A / B) has a running signal and the current is less than 35A (modifiable), a data point is collected every 3 seconds, and the difference (absolute value) is calculated with the current setting. A total of 5 data points are collected, and 4 out of the 5 differences are less than 1.5A (4 out of 5). When the crusher (A) has a running signal and the current is less than 35A (modifiable), a data point is collected every 3 seconds, and a total of 5 data points are collected. The difference (absolute value) is calculated between each data point and the operating current of the crusher (B). When any 3 of the differences are greater than the set value of 7A (modifiable), the following alarm prompts will pop up: "Crusher jammed, please stop feeding and check the crusher." The output shaft is driven by a servo motor to rotate, which in turn drives the guide frame to rotate, thereby driving the moving column to rotate. This, in turn, causes the impact column to squeeze and impact the protrusion, causing the crusher's outer shell to vibrate and improving the crusher's feeding efficiency. Under the deformation of the elastic element, the moving column can be pushed to slide along the surface of the guide frame and the limit plate to ensure the stability of the impact column's movement. Ultimately, this ensures that the impact column is always in contact with the protrusion, thus guaranteeing a good impact and vibration effect.
[0008] The beneficial effects of this utility model are as follows: This solution collects and analyzes the current signal of the crushing motor through a computer, analyzes the data collected by the computer, edits the logic control program, and sets abnormal alarm reminders, completely eliminating the situation where calcium carbide is stuck in the crushing chamber for a long time (≥15S) and cannot be detected on site. The amount of calcium carbide accumulated and weathered on site is reduced to 0t / day, and operators no longer need to spend time cleaning it every day. Through the use of servo motors, guide frames and other structures, the moving column can be driven to rotate, thereby driving the impact column to continuously impact and vibrate the protrusion, thereby using the crusher to vibrate and feed the material. Under the deformation of the elastic element, the contact effect of the impact column can be guaranteed.
[0009] Furthermore, a feeding mechanism is provided on the rear side of the crusher. The feeding mechanism includes a protrusion. The protrusion is welded to the rear side of the crusher. A support plate is welded to the rear side of the crusher and above the protrusion. A reinforcing rib is welded to the end face of the support plate. The long right-angle side of the reinforcing rib is welded to the crusher. A servo motor is fixedly installed on the upper end of the support plate. A guide frame is fixedly connected to the output shaft of the servo motor. A moving column is slidably sleeved on the outer side of the vertical part of the guide frame. An impact column is fixedly connected to the other end of the moving column. The impact column contacts the protrusion. Through the arrangement of the servo motor, guide frame, and other structures, the impact column can be driven to impact and vibrate the protrusion, thereby vibrating and feeding the crusher.
[0010] Furthermore, two reinforcing ribs are provided, which are symmetrically distributed on the support plate. The support plate can be reinforced by the reinforcing ribs.
[0011] Furthermore, four guide frames are provided, arranged in a circular array on the output shaft of the servo motor. The guide frames can be used to guide the movement of the moving column.
[0012] Furthermore, an elastic element is fixedly connected to the end face of the movable column near the output shaft of the servo motor, and the other end of the elastic element is fixedly connected to the output shaft of the servo motor. The movable column can be connected and used through the setting of the elastic element.
[0013] Furthermore, a limiting plate is fixedly sleeved on the outer side of the vertical part of the guide frame. The limiting plate is slidably connected to the moving column. The moving column can be guided by the limiting plate.
[0014] Furthermore, a limiting piece is fixedly connected to the lower end of the support plate. The limiting piece contacts the output shaft of the servo motor. By setting the limiting piece, the rotation of the output shaft of the servo motor can be limited. Attached Figure Description

[0021] The specific implementation process of this utility model is as follows: When the crusher 3 (A / B) has a running signal and the current is less than 35A (modifiable), a data point is collected every 3 seconds, and the difference (absolute value) is calculated with the current set by the crusher. A total of 5 data points are collected, and 4 of the 5 differences are less than 1.5A (4 out of 5); When the crusher 3 (A) has a running signal and the current is less than 35A (modifiable), a data point is collected every 3 seconds, and a total of 5 data points are collected.

Through the cooperation of servo motor 73, guide frame 74 and other structures, the moving column 75 can be driven to rotate, which in turn drives the impact column 78 to continuously impact and vibrate the protrusion 70, thereby vibrating and feeding the crusher 3. Under the deformation of the elastic element 76, the contact effect of the impact column 78 can be guaranteed.
