Description

Technical Field

[0001] The utility model belongs to the technical field of ore particle size detection, in particular to a belt conveyor ore material over-standard particle size detection and alarm device. Background Art

[0002] In the production process of ore in the mining system, the discharge port of the coarse crusher is too large due to the late use of the coarse crusher liner, resulting in the occasional appearance of large pieces exceeding 500mm in size during the production process. Such large pieces often get stuck on the upper part of the secondary crusher, causing leakage and ore overflow accidents, or fall into the crushing chamber of the crusher, causing the bolts of the crusher's movable cone and material plate to be sheared off. No matter which accident it is, it takes a long time to handle and consumes a lot of manpower and material resources. To address this issue, a camera is installed above each intermediate crusher feeding belt, and the image is directed to the central control room monitoring TV wall for centralized monitoring and management. Due to the high speed of the belts (2.1 meters per second) and the large number of belts, there are only three intermediate crusher feeding belts and as many as 15 other belts that need to be monitored. In addition, due to the influence of on-site dust and angle, the post cannot monitor the large pieces of material on the belt all the time. The post personnel are required to stand next to the running intermediate crusher feeding belt and check the ore particle size on the belt at all times. If large pieces of particle size exceeding the standard appear, the belt must be stopped and the large pieces exceeding the standard particle size must be moved off the belt, which increases the labor intensity of the post. Summary of the invention

[0003] The utility model aims to provide a belt conveyor ore material over-standard particle size detection and alarm device. During the belt transportation of iron ore, the ore with over-standard particle size appearing on the belt conveyor is detected, and an over-standard particle size alarm is automatically issued and the belt is stopped immediately, so as to prevent the ore from overflowing and the occurrence of crusher equipment accidents caused by the blockage of the ore with over-standard particle size. There is no need for post personnel to monitor the ore particle size all the time, so the labor intensity of post personnel is reduced.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] The utility model is a belt conveyor ore material excessive particle size detection and alarm device, which is characterized by comprising two bearing seat bases, two bearing seats arranged on the two bearing seat bases, a rotating shaft arranged between the two bearing seats, two rotating shaft arms perpendicular to the rotating shaft and arranged on the rotating shaft, two arm hoses respectively sleeved on the ends of the two rotating shaft arm arms, a pressure plate clip arranged at the end of one side of the rotating shaft, and a limit switch arranged below the pressure plate clip.

[0006] Advantages of the utility model:

[0007] (1) The utility model of the belt conveyor ore material over-standard particle size detection alarm device can flexibly and accurately send out an over-standard particle size alarm signal when ore material over-standard particle size appears during the operation of the belt conveyor, thereby avoiding the need for constant inspection by post personnel, reducing the labor intensity of post personnel, and preventing ore spillage and crusher equipment accidents caused by ore over-standard particle size;

[0008] (2) The utility model of the belt conveyor ore material over-standard particle size detection and alarm device is in soft contact with the ore through the rubber hose, without strong collision and vibration, resulting in a long service life of the device. The length of the rubber hose can be adjusted as needed to control the size of the over-standard particle size, which is convenient and quick;

[0009] (3) The utility model of the belt conveyor ore material over-standard particle size detection and alarm device requires common materials for manufacturing, has a simple structure, and is easy to manufacture and maintain. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The specific implementation of the present utility model is further described below in conjunction with the accompanying drawings.

[0013] like Figure 1 , 2 As shown, the utility model of the belt conveyor ore material excessive particle size detection and alarm device is characterized in that it includes two bearing seat bases 1, two bearing seats 4 arranged on the two bearing seat bases 1, a rotating shaft 5 arranged between the two bearing seats 4, two rotating shaft support arms 6 perpendicular to the rotating shaft 5 and arranged on the rotating shaft 5, two support arm hoses 7 respectively sleeved on the ends of the two rotating shaft support arms 6, a pressure plate clip 3 arranged at the end of one side of the rotating shaft 5, and a limit switch 2 arranged below the pressure plate clip 3. Specific implementation method:

[0015] (1) In the middle of the upper belt roller frame of the belt conveyor, two bearing seat bases 1 with a length of 1.2 meters are symmetrically welded, a square plate with two anchor holes is welded on the top of the bearing seat base 1, and two UCP207 bearing seats 4 are fixed by bolts;

[0016] (2) The shaft 5 is inserted into the inner holes of the two bearing seats 4, leaving 200 mm at the end of the shaft 5 to install the pressure plate clip 3 vertically downward, and the limit switch 2 is installed at an appropriate position below the pressure plate clip 3. The limit switch 2 is connected to the PLC input terminal through a cable;

[0017] (3) Two shaft support arms 6 with a spacing of 300 mm and a length of 400 mm are welded vertically downward in the middle of the shaft 5 between the two bearing seats 4, and a 1-inch support arm hose 7 is inserted into one end of the shaft support arm 6. The length of the support arm hose 7 can be adjusted according to the height of the material on the belt at the site;

[0018] (4) In actual application, when the belt conveyor is in operation, ore materials with excessive particle size appear. Since the ore is too large and exceeds the normal material height, it scrapes the lower end of the support arm hose 7 of the excessive particle size detection and alarm device, driving the rotating shaft 5 to rotate, causing the pressure plate clip 3 fixed at one end of the rotating shaft 5 to rotate and touch the limit switch 2. The limit switch 2 is activated to issue an excessive particle size alarm and shut down the machine. After the ore materials with excessive particle size pass through, due to the gravity of the support arm hose 7, the rotating shaft support arm 6 and the pressure plate clip 3, they return to their original vertical downward position and wait for the next action without manual reset.

[0019] The utility model discloses a belt conveyor ore material over-standard particle size detection and alarm device, which can automatically stop the belt and send out an over-standard alarm for the ore exceeding the standard particle size on the belt conveyor. After the personnel on duty clear the large pieces of over-standard particle size and reset the alarm, the belt resumes operation, which greatly reduces the labor intensity of the post.

[0020] The utility model of the belt conveyor ore material over-standard particle size detection alarm device can flexibly and accurately send out an over-standard particle size alarm signal when ore material over-standard particle size appears during the operation of the belt conveyor, thereby avoiding constant inspection by personnel on duty, reducing the labor intensity of personnel on duty, and preventing ore spillage and crusher equipment accidents caused by ore over-standard particle size; the ore is in soft contact through the support arm hose 7, without strong collision and vibration, resulting in a long service life of the device; the support arm hose 7 can be adjusted in length as needed to control the size of the over-standard particle size, which is convenient and quick;

[0021] The utility model discloses a belt conveyor ore material over-standard particle size detection and alarm device, which requires common materials for manufacturing, has a simple structure, and is easy to manufacture and maintain.
