Description

Technical Field

[0001] This utility model relates to the field of flotation reagent addition technology in coal washing plants, and in particular to a flotation reagent addition device for coal washing plants. Background Technology

[0002] A coal washing plant is a processing plant that removes mineral impurities from raw coal. It can be divided into coking coal preparation plants and power coal preparation plants, etc. Its main products are clean coal and lump coal, as well as by-products such as middlings. Coal washing is an indispensable process in the deep processing of coal. Coal directly mined from the mine is called raw coal. During the mining process, raw coal is mixed with many impurities, and the quality of coal is also different. Coal with low internal ash content and coal with high internal ash content are mixed together. Coal washing is an industrial process that removes impurities from raw coal or separates high-quality coal from low-quality coal. Coal washing plants involve many processes, including the flotation process of slurry. During this process, a dosing device is used to add flotation agents. In order to ensure the effect of subsequent flotation of slurry, the dosing device needs to fully mix the slurry and flotation agent. However, traditional flotation dosing devices are not convenient for cleaning the stirring rod, and the material is prone to clogging, resulting in incomplete discharge.

[0003] Therefore, those skilled in the art have provided a flotation reagent dosing device for coal washing plants to solve the problems mentioned in the background art. Utility Model Content

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] Example 1:

[0035] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 A flotation dosing device for a coal washing plant includes a dosing hopper 1. A material mixing component 2 is installed on the top of the dosing hopper 1. The material mixing component 2 includes a first motor 201. An agitator 202 is fixedly installed on the output shaft of the first motor 201. An agitator blade 203 is fixedly installed on the surface of the agitator 202. A conveying auger 204 is fixedly installed on the bottom of the agitator 202. A material plug 205 is fixedly installed on the bottom of the conveying auger 204. A discharge pipe 4 is connected to the bottom of the dosing hopper 1. The inner wall of the discharge pipe 4 is in contact with the material plug 205. The agitator blade 203 is a metal blade, and the surface of the agitator blade 203 is coated with a corrosion-resistant coating. An mounting base 5 is fixedly installed on the other side of the dosing hopper 1, and mounting holes are opened around the mounting base 5.

[0036] In this embodiment: by setting up a material mixing component 2, the stirring rod 202 can be rotated by turning on the first motor 201, thereby driving the stirring blade 203 to mix the slurry and flotation agent. The material plug 205 can prevent material overflow, and the discharge pipe 4 can discharge material. The inner wall of the discharge pipe 4 is in contact with the material plug 205, so that the material plug 205 can block the material. The metal blades ensure the service life of the stirring blade 203, and the corrosion-resistant coating increases the corrosion resistance of the stirring blade 203.

[0037] Example 2:

[0038] Reference Figure 1-4 An adjustment assembly 3 is provided on one side of the dosing hopper 1. The adjustment assembly 3 includes an adjustment box 301. A second motor 302 is fixedly installed at the bottom of the inner cavity of the adjustment box 301. A one-way threaded rod 303 is fixedly installed on the output shaft of the second motor 302. An adjustment screw block 304 is threadedly connected to the surface of the one-way threaded rod 303. A positioning rod 306 is fixedly installed on one side of the adjustment screw block 304. The positioning rod 306 is fixedly connected to the first motor 201. The adjustment box 301 is fixedly connected to the dosing hopper 1. The surface of the adjustment box 301 is coated with an anti-rust coating. A positioning bearing is fixedly installed at the top of the inner cavity of the adjustment box 301, and the positioning bearing is rotatably connected to the one-way threaded rod 303. Guide sliders 305 are fixedly installed on both the front and rear sides of the adjustment screw block 304. A guide groove is opened in the inner cavity of the adjustment box 301.

[0039] In this embodiment: by setting an adjustment component 3, the material mixing component 2 can be moved downward or upward by controlling the forward and reverse rotation of the second motor 302. When moving downward, the material plug 205 can be disengaged from the discharge pipe 4 for easy discharge. When moving upward, the material mixing component 2 can be brought out for easy cleaning. The dosing hopper 1 can support the adjustment box 301. The anti-rust coating increases the anti-rust performance of the adjustment box 301. The positioning bearing can position the one-way threaded rod 303 to prevent it from tilting. The guide slider 305 works with the guide groove to guide the adjustment screw block 304, making the adjustment screw block 304 stable when moving. Bolts are inserted into the mounting hole to fix the mounting base 5, thereby fixing the device.

[0040] The implementation principle of this utility model is as follows: In use, turning on the first motor 201 drives the stirring rod 202 to rotate, which in turn drives the stirring blade 203 to mix the slurry and flotation agent. The material plug 205 prevents material overflow. Controlling the second motor 302 to rotate forward drives the one-way threaded rod 303 to rotate. The one-way threaded rod 303 drives the adjusting screw block 304 to move downward. The adjusting screw block 304 drives the positioning rod 306 to move downward, which in turn drives the material mixing component 2 to move downward as a whole. The material plug 205 disengages from the discharge pipe 4. At this time, turning on the first motor 201 again drives the conveying auger 204 to rotate through the stirring rod 202 to avoid material blockage. After the discharge is completed, controlling the second motor 302 to reverse reverse drives the material mixing component 2 to move upward as a whole, which allows the material mixing component 2 to disengage from the dosing hopper 1 for easy cleaning.

[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
