Description

Technical Field

[0001] This utility model relates to a side unloading device for a belt conveyor. Background Technology

[0002] In projects such as straw power plants and industrial solid waste power plants, the storage capacity of the boiler's front-furnace silos is small. According to feedback from multiple projects, a single front-furnace silo actually only has a storage capacity of 5 to 15 minutes. When one feeding belt conveyor supplies material to multiple front-furnace silos, the conventional unloading equipment is an electric plow-type unloader. Each silo has at least one unloader at the top. When the plow head of a certain unloader is pressed down, all the material on the belt conveyor is unloaded at that point. Therefore, material can only be fed into each silo one by one, requiring frequent switching of the unloader's state (pressing down or raising the plow head), resulting in a heavy workload for operators. Pressing down the unloader's plow head can cause material to get stuck between the plow head and the conveyor belt, damaging the conveyor belt joint and increasing conveyor belt wear. The open inlet of the chute funnel on the side of the unloader causes serious dust pollution, polluting the working environment. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned deficiencies in the existing technology and provide a belt conveyor side unloading device with a reasonable structural design. It can realize continuous and stable feeding of multiple furnace front hoppers without frequent start-up and shutdown or switching of unloading equipment, and can effectively prevent damage to the conveyor belt and effectively reduce dust overflow.

[0004] The technical solution adopted by this utility model to solve the above problems is: a side unloading device for a belt conveyor, including a support and a discharge hopper; characterized in that: it also includes a drive device, a dial wheel, and a dust cover; the support is fixedly installed on the unloading section of the belt conveyor; the drive device is fixed on the support; the dial wheel is located above the belt conveyor, and the dial wheel includes a dial wheel shaft and a dial plate; the dial wheel shaft is rotatably installed on the support, so that the material feeding direction of the dial wheel is the lateral direction of the belt conveyor; the drive device is connected to the dial wheel shaft; the dial plate is fixedly installed on the dial wheel shaft; the dust cover is fixed on the support, covering the dial wheel, the unloading section of the belt conveyor, and the inlet of the discharge hopper.

[0005] The support frame described in this utility model is in the form of a gantry frame, spanning across the unloading section of the belt conveyor.

[0006] The rotation axis of the dial shaft described in this invention is oriented towards the material flow direction of the belt conveyor.

[0007] This utility model also includes a transmission device, and the drive device is connected to the dial wheel shaft through the transmission device.

[0008] The lowest point of the dial shaft described in this invention is higher than the highest point of the material on the belt conveyor.

[0009] The front end of the paddle described in this utility model is fixed with a soft sheet.

[0010] This utility model also includes a waste material guide plate, which is fixedly installed on the side of the unloading section of the belt conveyor.

[0011] Compared with the prior art, this utility model has the following advantages and effects:

[0012] 1. It can achieve continuous and stable feeding of multiple furnace front hoppers without frequent start-up and shutdown or switching of unloading equipment, and the feeding ratio of each hopper can be controlled; it improves system safety and reduces the labor intensity of workers;

[0013] 2. In the conveying process of this utility model, unlike the traditional belt conveyor side unloading equipment that uses baffles to change the material flow direction to achieve side unloading of bulk materials, this utility model uses a pulley to apply a force perpendicular to the material flow direction to achieve side unloading of the belt conveyor.

[0014] 3. In the process of conveying bulk materials, this utility model differs from the traditional belt conveyor side unloading equipment, which can only unload all materials. This utility model can unload partially or completely, and partial unloading does not affect the continued conveying of the remaining materials on the belt conveyor.

[0015] 4. In the process of conveying bulk materials, when one belt conveyor feeds materials to multiple silos, unlike the traditional plow-type unloader which can only feed materials to one silo at a time, this utility model can achieve simultaneous feeding of multiple silos and can adjust the feeding ratio of each silo.

[0016] 5. Equipped with a dust cover, which can effectively reduce dust spillage and improve the working environment. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0023] This embodiment includes a bracket 4, a drive device 5, a dial wheel, a transmission device 6, a material discharge hopper 10, a residual material guide plate 11, and a dust cover 12.

[0024] The support frame 4 is fixedly installed on the unloading section of the belt conveyor 3, and can be fixed to the intermediate frame 1 of the belt conveyor 3, the ground, or the floor. The support frame 4 is in the form of a gantry frame, spanning across the unloading section of the belt conveyor 3. The idlers 2 at the unloading section and its front and rear positions of the belt conveyor 3 are flat idlers, which flatten the conveyor belt in the unloading section, facilitating material flowout and allowing residual material to be re-gathered by the guide plate.

[0025] The drive unit 5 is fixed to the top of the bracket 4. In this embodiment, the drive unit 5 uses a geared motor, but different types of drive units can also be used flexibly, such as a geared motor assembly, a motor + DCY or ZSY reducer, a motor + cycloidal pinwheel / planetary gear reducer, etc. The geared motor uses a dedicated frequency converter motor to provide optimal performance.

[0026] The dial wheel is rotatably mounted on the bracket 4 and located above the belt conveyor 3. The dial wheel includes a dial wheel shaft 7 and a dial plate 8.

[0027] The dial wheel shaft 7 is rotatably mounted on the bracket 4, with its rotation axis facing the material flow direction of the belt conveyor 3. Thus, the dial wheel's material-discharging direction is laterally to the belt conveyor 3. The drive unit 5 is connected to the dial wheel shaft 7 via a transmission device 6, or the reducer output shaft of the drive unit 5 can be directly connected to the dial wheel shaft 7. The drive unit 5 drives the dial wheel to rotate, and the transmission device 6 uses a chain drive. The lowest point of the dial wheel shaft 7 and the sprockets of the transmission device 6 is higher than the highest point of the material on the belt conveyor 3, with a margin to prevent the material from affecting the normal operation of the dial wheel shaft. After production begins, the drive unit 5 is mainly adjusted by regulating the output frequency of the frequency converter, thereby adjusting the dial wheel speed and achieving the purpose of adjusting the unloading ratio. By adjusting the frequency, the unloading ratio can be continuously adjusted within a certain range.

[0028] The paddle 8 is fixedly mounted on the paddle wheel shaft 7. The angle α between the front end and the root of the paddle 8 is variable, and can be positive (as shown in the attached diagram), negative, or 0. A positive angle can better reduce material carryover when the paddle rotates out of the material pile. The paddle 8 does not directly contact the conveyor belt of the belt conveyor 3, thus avoiding damage to the conveyor belt. A flexible piece 9 is fixed to the front end of the paddle 8 by bolts. The flexible piece 9 is made of soft material, ensuring close contact between the end of the flexible piece 9 and the conveyor belt while avoiding direct or indirect scratches to the conveyor belt. In this embodiment, there are 6 paddles 8, but different numbers of paddles can be used in specific implementations.

[0029] The discharge hopper 10 and the residual material guide plate 11 are both fixedly installed on the side of the unloading section of the belt conveyor 3.

[0030] The dust cover 12 is fixed on the bracket 4, covering the feed wheel, the unloading section of the belt conveyor 3, and the inlet of the discharge hopper 10.

[0031] Only the inlet and outlet holes for the belt conveyor 3 are provided. The dust cover 12 is equipped with a dust extraction port 13, which, together with the dust collector and dust extraction fan, can effectively reduce dust overflow and improve the working environment.

[0032] The drive unit 5 drives the dial wheel shaft 7 to rotate via the transmission device 6. The dial wheel shaft 7 drives the paddle plate 8 to rotate, discharging the material on the belt conveyor 3 laterally into the discharge hopper 10, achieving partial or complete unloading. The residual material guide plate 11 gathers the remaining material back onto the conveyor belt of the belt conveyor 3, allowing it to enter the downstream conveying stage. The unloading ratio can be adjusted by changing the dial wheel speed, the number of paddle plates, and their length. The dial wheel speed can be adjusted by setting the frequency of the frequency converter, selecting the reduction ratio of the reducer, and selecting the reduction ratio of the transmission device.

[0033] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model patent concept are included within the protection scope of this utility model patent. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined in these claims, all of which should fall within the protection scope of this utility model.
