Description

Technical Field

[0001] This utility model relates to the field of iron ore pellet production technology, specifically to an online monitoring device for iron ore pellet forming. Background Technology

[0002] Iron ore pellets are made by mixing various iron concentrates or finely ground natural minerals with water and pellet binders to form green pellets, which are then roasted at high or low temperatures to produce pellet ore. Pellet ore has the characteristics of high iron content, uniform particle size, good reducibility, high mechanical strength, and good storage resistance. After the iron ore pellets are produced and formed, they need to be monitored and screened to remove defective products.

[0003] The Chinese utility model patent with authorization announcement number "CN222428608U" is specifically "an online monitoring device for iron ore pellet forming". It transmits signals to a cylinder through a controller. The cylinder drives a pusher plate to move, which pushes out the broken pellets in the placement seat and allows the broken pellets to enter the collection box. The pellets can be monitored and screened to separate the broken pellets from the whole pellets, thereby facilitating the subsequent processing of the intact pellets.

[0004] While the aforementioned devices can monitor the formation of iron ore pellets, they cannot obtain the number of defective pellets, affecting the company's analysis of the defect rate. Therefore, we propose an online monitoring device for iron ore pellet formation. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an online monitoring device for iron ore pellet forming, which can effectively solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides an online monitoring device for iron ore pellet forming, including a pellet conveyor belt, a monitoring mechanism and a collection mechanism arranged on the outside of the pellet conveyor belt; The monitoring mechanism includes a U-shaped cover fixedly connected to the outside of the pellet conveyor belt, a shape recognition sensor installed inside the U-shaped cover, a controller installed outside the U-shaped cover, a servo motor installed inside the U-shaped cover, a disk fixedly connected to the output shaft of the servo motor, and equally spaced rejection rods fixedly connected to the outside of the disk. A housing is provided on the top of the U-shaped cover, and a press counter is provided inside the housing. The collection mechanism includes a guide pipe disposed on the outside of the pellet conveyor belt, a collection box disposed below the guide pipe, a filter screen installed inside the collection box, and a dust box disposed below the filter screen.

[0007] Preferably, an L-shaped frame is fixedly connected to the outside of the housing, and the L-shaped frame is fixedly connected to the outside of the U-shaped cover.

[0008] Preferably, a numerical display screen is mounted on the outside of the L-shaped frame, and the numerical display screen is electrically connected to the controller and the press counter.

[0009] Preferably, a spring is fixedly connected to the inner side of the housing, and a contact block is fixedly connected to the other end of the spring.

[0010] Preferably, a push rod is fixedly connected to the top of the contact block, and the bottom of the contact block is arc-shaped.

[0011] Preferably, a fixing block is fixedly connected to the outside of the guide pipe, and the fixing block is fixedly connected to the outside of the pellet conveyor belt.

[0012] Preferably, the collection box has an installation groove on its outer side, the dust box is installed inside the installation groove, and an L-shaped support plate is fixedly connected to the outer side of the pellet conveyor belt, with the dust box placed on the L-shaped support plate.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This utility model, by setting up a monitoring mechanism, allows shape recognition sensors to detect whether the pellets on the pellet conveyor belt are intact when the pellets are being transported after production. When defects are found, the controller activates a servo motor, and the rotation of the rejection rod removes the defective pellets from the conveyor belt. The number of rejections can be calculated when the rejection rod removes defective pellets, thus facilitating the company's analysis of the defect rate in pellet production.

[0014] 2. By setting up a collection mechanism, the defective pellets rejected by the monitoring mechanism can enter the collection box under the action of the guide pipe. Under the action of the filter screen, the pellets and the dust carried on their exterior can be separated, which facilitates the separate processing of defective pellets and dust in the future.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] Example 1: Reference Figure 1-4 This is the first embodiment of the present utility model, which discloses an online monitoring device for iron ore pellet forming, including a pellet conveyor belt 1, a monitoring mechanism 2 for online identification of broken pellets and removal and counting is provided on the outside of the pellet conveyor belt 1, and a collection mechanism 3 for recycling removed pellets and separating dust is provided on the outside of the pellet conveyor belt 1. The monitoring mechanism 2 includes a U-shaped cover 202 fixedly connected to the outside of the pellet conveyor belt 1, covering a section of the conveying path. A shape recognition sensor 209 is installed inside the U-shaped cover 202 for real-time monitoring of the shape integrity of the passing pellets. A controller 203 is set outside the U-shaped cover 202, and a servo motor 208 is installed inside the U-shaped cover 202. Its drive signal receiving end is connected to the controller 203. A disk 201 is fixedly connected to the output shaft of the servo motor 208. A rejection rod 207 with equal spacing is fixedly connected to the outside of the disk 201. A housing 205 is set on the top of the U-shaped cover 202, and a press counter 213 is set inside the housing 205.

[0021] Specifically, an L-shaped frame 204 is fixedly connected to the outside of the housing 205. The L-shaped frame 204 is fixedly connected to the outside of the U-shaped cover 202 and is used to support the housing 205 and the display screen.

[0022] Specifically, a numerical display screen 206 is installed on the outside of the L-shaped frame 204. The numerical display screen 206 is electrically connected to the controller 203 and the press counter 213 to display the cumulative number of broken pellets recorded by the press counter 213 in real time.

[0023] Specifically, a spring 212 is fixedly connected to the inner side of the housing 205, and a contact block 210 is fixedly connected to the other end of the spring 212. A push rod 211 is fixedly connected to the top of the contact block 210. The bottom of the contact block 210 is arc-shaped. The position of this arc surface is designed so that when the rejecting rod 207 rotates with the disc 201 to a specific position, such as near the lowest point, it can contact and push the contact block 210 to move upward against the force of the spring 212. The upward movement of the push rod 211 will press and trigger the press counter 213 inside the housing 205 to count.

[0024] Example 2: Reference Figure 1-2 and Figure 5 This is the second embodiment of the present invention, which differs from the first embodiment in that: The collection mechanism 3 includes a guide pipe 302 located outside the pellet conveyor belt 1. Its inlet end receives broken pellets knocked down by the rejection rod 207, and its outlet end extends downwards. A collection box 301 is located below the guide pipe 302 to collect and temporarily store the rejected broken pellets. A filter screen 306 is installed inside the collection box 301, located at the bottom of the collection area inside the box. This filter screen receives the falling broken pellets and allows dust adsorbed on their exterior to permeate downwards. A dust box 307 is located below the filter screen 306 to collect dust that settles through the filter screen 306. This layered design achieves the physical separation and collection of broken pellets and dust.

[0025] Specifically, a fixing block 303 is fixedly connected to the outside of the guide pipe 302. The fixing block 303 is fixedly connected to the outside of the pellet conveyor belt 1 to ensure that the guide pipe 302 is in a stable position and aligned with the rejection area.

[0026] Specifically, the collection box 301 has an installation groove 305 on its outer side, and the dust box 307 is installed inside the installation groove 305 for easy periodic removal and cleaning. The pellet conveyor belt 1 is fixedly connected to an L-shaped support plate 304, and the dust box 307 is placed on the L-shaped support plate 304 to provide load-bearing support and assist in positioning.

[0027] The remaining structure is the same as that in Example 1.

[0028] The workflow of this utility model is as follows: The pellet conveyor belt 1 transports the produced pellets. When the pellets are transported to the U-shaped cover 202, the shape recognition sensor 209 monitors and identifies the transported pellets. When a damaged pellet is detected, the sensor sends a signal to the controller 203. The controller 203 then sends the signal to the servo motor 208. The servo motor 208 drives the disc 201 to rotate a quarter turn. The rotation of the disc 201 removes the damaged pellets through the rejection rod 207. When the removal rod 207 removes the broken pellets, the removal rod 207 rotates and pushes the contact block 210 to move upward. The upward movement of the contact block 210 squeezes and presses the counter 213 through the push rod 211, and the damage value is displayed on the numerical display screen 206. The pellets removed by the removal rod 207 enter the guide tube 302 and then enter the collection box 301 below for collection. The dust adsorbed on the outside passes through the filter screen 306 and enters the dust box 307 below for collection. The pellets on the dust box 307 and the filter screen 306 are periodically removed for corresponding treatment.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
