Technical Field

[0001] This utility model relates to the field of briquette production, specifically to a briquette feeding device and feeding system. Background Technology

[0002] Briquette production is a top investment choice for energy conservation and emission reduction in the coal industry. Fine coal powder is difficult to ignite and inconvenient to transport and use, so briquetting equipment is typically used to press it into spherical, oval, or square shapes. Briquette production lines can compress dried coal slime, ash, and other loose coal products into briquettes, coke briquettes, and various carbon products for direct smelting and application. They can also utilize iron powder to press sponge iron and various mineral powders into briquettes.

[0003] The existing briquette production process mainly includes: raw material preparation, crushing and screening, mixing and stirring, molding, drying, and post-processing. Briquettes dried in the drying kiln typically need to be transported to finished product bins via conveyor belts for storage. However, under normal circumstances, briquettes need to be transported to multiple finished product bins via multiple unloading conveyor belts. These multiple conveyor belts occupy a lot of space, and the equipment and processes are complex, prolonging transportation time, reducing work efficiency, and increasing the probability of briquette damage, thus lowering the yield. Utility Model Content

[0004] This invention addresses the problem that existing technologies require multiple unloading conveyor belts to transfer briquettes, resulting in significant space consumption, long transportation times, and reduced work efficiency and yield. It provides a briquette unloading device and system that can automatically and quickly unload briquettes and gangue from a single conveyor belt into multiple different finished product bins, eliminating the need for additional unloading conveyor belts.

[0038] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0039] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0040] Example 1

[0041] After drying, existing briquettes need to be transferred to multiple finished product bins via multiple unloading conveyor belts for storage. These multiple conveyor belts take up a lot of space, and the equipment and processes are complex, which prolongs transportation time, reduces work efficiency, increases the chance of briquettes being damaged, and reduces the yield of finished products.

[0042] To address the aforementioned problems in the prior art, this embodiment provides a briquette feeding device. This device is installed on a conveyor belt carrying dried briquettes and gangue, and is used to feed the briquettes and gangue from the conveyor belt into finished product bins on both sides of the conveyor belt. This briquette feeding device can automatically and quickly feed briquettes and gangue from one conveyor belt into multiple different finished product bins, eliminating the need for additional unloading belts. Please refer to [link / reference]. Figures 1-4 The coal feeding device mainly includes: mounting frame 100, cylinder 200 and material blocking assembly 300, etc.

[0043] The mounting frame 100 is positioned above the belt conveyor track 500 for briquettes and gangue, used to support and maintain the stability of other components and parts, ensuring a reasonable distance between them and the belt conveyor track 500. For example... Figure 1 , Figure 2 As shown, the mounting frame 100 mainly includes support rods 110, a crossbeam 120, and a first hinge seat 130. Two support rods 110 are symmetrically arranged on both sides of the support of the belt conveyor track 500, perpendicular to the transmission direction of the belt conveyor track 500 and extending towards the side where the upper surface of the belt is located. The ends of the two support rods 110 away from the support of the belt conveyor track 500 are connected by the crossbeam 120. The first hinge seat 130 is located in the middle of the crossbeam 120, and includes two symmetrically arranged hinge plates with hinge holes. The space between the two hinge plates is used to house the cylinder 200.

[0044] A cylinder 200 is mounted on the mounting bracket 100 and is used to drive the material stop assembly 300, allowing it to switch between different positions. The cylinder 200 mainly consists of a fixed end 210 and a telescopic rod 220. A first rotating member 230 is provided on the side of the fixed end 210 away from the telescopic rod 220. A first hinge shaft 232 passes through the first rotating member 230, and both ends of the first hinge shaft 232 extend outward from both sides of the first rotating member 230 and are hinged to a first hinge seat 130, allowing the fixed end 210 of the cylinder 200 to rotate relative to the crossbeam 120. Simultaneously, a second hinge seat 222 is provided on the end of the telescopic rod 220 away from the fixed end 210, and the second hinge seat 222 is used to connect the cylinder 200 and the material stop assembly 300.

[0045] The material blocking assembly 300 is mounted on the mounting frame 100 and is used to change the movement direction of the briquettes and gangue on the belt conveyor track 500, allowing them to be unloaded from the belt conveyor track 500 and stored in the finished product bins on both sides. In this embodiment, the material blocking assembly 300 has a roughly triangular material blocking head 310, which is located above the upper surface of the belt of the belt conveyor track 500; in one or more other embodiments, the material blocking head 310 may also be arc-shaped, trapezoidal, or other shapes. In addition, two rotating rods 320 are symmetrically arranged on both sides of the material blocking head 310, and the other ends of the two rotating rods 320 are respectively rotatably mounted on the two support rods 110 of the mounting frame 100 via rotating shafts, so that the material blocking assembly 300 can rotate relative to the mounting frame 100 with the other end of the rotating rod 320 as the axis. Meanwhile, a connecting rod 330 is provided between the two rotating rods 320 and near the stop head 310. A second rotating member 340 is provided in the middle of the connecting rod 330. A second hinge shaft 342 is provided on the second rotating member 340. The two ends of the second hinge shaft 342 extend outward from both sides of the second rotating member 340 and are hinged to the second hinge seat 222, so that the stop assembly 300 and the telescopic rod 220 can also rotate relative to each other.

[0046] One specific working method of this embodiment is as follows:

[0047] First, the belt conveyor track 500 is started to transport briquettes and gangue. When no material is needed, the telescopic rod 220 of the cylinder 200 retracts. Relying on the rotation of the first hinge shaft 232, the second hinge shaft 342, and the shaft between the rotating rod 320 and the support rod 110, the baffle head 310 is driven to rotate away from the belt surface, maintaining a position with a certain distance from the belt, in an open state, not affecting the passage of briquettes and gangue on the belt. When material needs to be discharged, the telescopic rod 220 of the cylinder 200 extends. Relying on the rotation of the first hinge shaft 232, the second hinge shaft 342, and the shaft between the rotating rod 320 and the support rod 110, the baffle head 310 is driven to rotate closer to the belt surface, maintaining a position in contact with the upper surface of the belt, in a blocking state, which can block the passage of briquettes and gangue on the belt, causing the briquettes and gangue to turn and be discharged into the finished product bins on both sides.

[0048] In this embodiment, the briquette feeding device uses a mounting frame 100 above the belt conveyor track 500 and a material-blocking component 300 rotatably mounted on the mounting frame 100. By extending and retracting a cylinder 200 rotatably mounted between the mounting frame 100 and the material-blocking component 300, the movement of the material-blocking component 300 relative to the belt surface is controlled, thereby feeding the material on the belt. This achieves automatic and rapid feeding of briquettes and gangue from one conveyor belt into multiple different finished product bins, solving the problems in the prior art where briquettes need to be transferred through multiple unloading belts, which takes up a lot of space, has a long transportation time, and affects work efficiency and yield.

[0049] Furthermore, in this embodiment, discharge ports 400 are symmetrically arranged on both sides of the belt conveyor track 500, and the discharge ports 400 are inclined discharge pipes. Simultaneously, the inlet of the discharge port 400 is directly opposite the position of the baffle head 310 of the baffle assembly 300 when it is in a blocked state; and the outlet of the discharge port 400 is connected to the finished product bin below; thus, the discharge port 400 can quickly and efficiently transport the coal and gangue fed from the belt conveyor to the finished product bin below. In addition, an extension plate 410 extending towards the belt is provided at the bottom of the inlet of the discharge port 400. The extension plate 410 is used to prevent the coal and gangue fed from the belt conveyor from falling into the gap between the discharge port 400 and the belt, preventing waste of briquettes and increasing the workload of briquette recycling.

[0050] Specifically, in this embodiment, inclined side baffles 350 are symmetrically arranged on both sides of the material stop head 310. The side baffles 350 are used to prevent the coal and gangue from rushing out of the inlet area of ​​the discharge port 400 when it is discharged to the sides at too high a speed, thereby causing waste of briquettes and increasing the workload of briquette recycling. In addition, baffles 360 are provided on the outer surfaces of both the material stop head 310 and the side baffles 350. The baffles 360 are made of an elastic material similar to the belt material, so that they can fit more tightly with the belt and reduce the damage to the belt caused by contact friction.

[0051] Specifically, in this embodiment, a first limiting component 370 is provided above the material blocking component 300, and a second limiting component 420 cooperating with the first limiting component 370 is provided on the discharge port 400 to limit the position of the material blocking component 300 and prevent the material blocking head 310 from excessively squeezing the belt and affecting the normal operation of the belt. The first limiting component 370 is located above the material blocking head 310, is roughly rod-shaped, and is horizontally arranged perpendicular to the belt transmission direction. Both ends of the first limiting component 370 have grooves 372 that align with the second limiting component 420. The second limiting component 420 is vertically arranged on the side wall of the discharge port 400, and its upper end has an abutment plate 422 that aligns with the groove on the first limiting component 370. Meanwhile, a baffle plate 374 is also provided on the side of the first limiting component 370 near the tip of the baffle head 310. The baffle plate 374 is used to prevent coal and gangue on the belt from rushing over the baffle head 310 and entering the rear belt when turning. Furthermore, when the baffle head 310 reaches its limit position near the surface of the belt, there is a gap between the baffle head 310 and the belt surface. The width of the gap is smaller than the diameter of the coal and gangue briquettes transported on the belt, so that the coal and gangue on the belt can be discharged into the finished product bins on both sides, while the pulverized coal or broken briquettes on the belt are sent to the rear transfer bin for further processing.

[0052] Example 2

[0053] Based on the above embodiments, a briquette feeding system is further proposed, and a second embodiment is provided below.

[0054] Please see Figures 1-4 The briquette feeding system in the second embodiment mainly includes a belt conveyor track 500, the briquette feeding device from the above embodiment, and a finished product bin (not shown in the figure). The briquette feeding device is located above the belt conveyor track 500, and one or more sets can be installed, depending on the number of finished product bins below. The finished product bins are located below each briquette feeding device on both sides, connected to the discharge ports 400 on both sides of the briquette feeding device. In use, the briquettes and gangue are first transported via the belt conveyor track 500, and during transportation, they are turned and discharged by the briquette feeding device, then fall into the finished product bin for storage and collection.

[0055] In this embodiment, the briquette feeding system uses a mounting frame 100 above the belt conveyor track 500 and a material-blocking component 300 rotatably mounted on the mounting frame 100. By extending and retracting a cylinder 200 rotatably mounted between the mounting frame 100 and the material-blocking component 300, the material-blocking component 300 is controlled to move closer to or further away from the belt surface, thereby feeding material onto the belt. This achieves automatic and rapid feeding of briquettes and gangue from one conveyor belt into multiple different finished product bins, solving the problems in the prior art where briquettes need to be transferred through multiple unloading belts, which takes up a lot of space, has a long transportation time, and affects work efficiency and yield.
