During the processing of mineral slurry, the required reagents need to be added and the mixture needs to be thoroughly stirred.

[0003] Because the slurry will flow to the side of the slurry pretreatment tank under the action of centrifugal force when it is stirred, although the existing technology uses the addition of the reagent to the stirring rod, the slurry located on the side is difficult to be fully stirred. At the same time, relying solely on stirring still has the technical problem of low efficiency in mixing the reagent evenly.

[0004] Therefore, a coal preparation slurry pretreatment device is proposed. Utility Model Content

[0011] Furthermore, a filter screen is provided on the flow divider plate, the exhaust pipe is located above the filter screen, and the feed pipe is located below the filter screen.

[0012] Furthermore, the connecting main pipe is provided with two sections, the two parts of which are respectively located on the upper and lower sides of the diversion plate. The connecting main pipe and the interior of the diversion plate are connected, and the connecting main pipe located in the upper part extends to the outside of the slurry pretreatment tank.

[0013] The beneficial effects of this utility model are as follows:

[0023] like Figure 1-3As shown, a coal preparation slurry pretreatment device includes a support plate 1, on which a slurry pretreatment tank 2 is mounted. The slurry pretreatment tank 2 is equipped with an inlet pipe 201, a discharge pipe 202, and an exhaust pipe 203. A stirring component 3 for agitating the slurry is installed inside the slurry pretreatment tank 2. The stirring component 3 includes a diversion plate 304 rotatably mounted inside the slurry pretreatment tank 2 and a motor 301 mounted at the bottom of the slurry pretreatment tank 2. A connecting main pipe 302 is connected to the middle of the diversion plate 304, and the connecting main pipe 302 is connected to the motor. The main shaft end of 301 is connected to the slurry pretreatment tank 2, which is equipped with an automatic reagent addition component 5 and a pressurizing component 6 for atomizing and pressurizing the reagent. The reagent addition component 5 includes a reagent storage tank 501 located at the top of the slurry pretreatment tank 2. A water pump 502 is installed inside the reagent storage tank 501. The output end of the water pump 502 is connected to a first connecting pipe 503, which is rotatably connected to the main connecting pipe 302. The pressurizing component 6 includes an air pump 601 located at the top of the slurry pretreatment tank 2. The air pump 601 delivers... The outlet is connected to a second connecting pipe 602, which extends into the interior of the first connecting pipe 503. Specifically, a stirring component 3 is provided, which can drive the diversion plate 304 to rotate, thereby driving the main connecting pipe 302 and the side stirring plate 305 to rotate around the main shaft of the motor 301, thus stirring the slurry. During the stirring process, the dosing component 5 and the pressurizing component 6 are provided, which can add the chemical solution. Under the action of the pressurizing component 6, the chemical solution can be added into the slurry pretreatment tank 2. High-pressure gas, since the liquid medicine and high-pressure gas are in the same flow channel, the liquid medicine discharged out through the first stirring tube 303 and the second stirring tube 306 is high-pressure atomized liquid medicine, which can make the liquid medicine sprayed into the interior of the slurry more evenly. At the same time, under the turbulence of the gas, the mixing efficiency of the slurry and the liquid medicine is further improved. The gas can then be discharged out through the exhaust pipe 203 to the slurry pretreatment tank 2. The filter screen 4 can break up the gas and prevent the slurry from overflowing out through the exhaust pipe 203 in the form of bubbles.

[0024] like Figure 1 As shown, a support leg is provided at each of the four corners of the bottom of the support plate 1, and an anti-slip pad is provided at the bottom of the support leg.

[0025] like Figure 2As shown, multiple first stirring tubes 303 are evenly arranged on the connecting main pipe 302, and a side stirring plate 305 is provided at the bottom end of the diversion plate 304. The side stirring plate 305 is located away from the center of the connecting main pipe 302, and multiple evenly arranged second stirring tubes 306 are provided on one side of the side stirring plate 305. Each first stirring tube 303 and each second stirring tube 306 is provided with a one-way valve 307 inside. Specifically, the side stirring plate 305 can stir the slurry located on the side of the slurry pretreatment tank 2, thus making the stirring more uniform and thorough.

[0026] like Figure 2 As shown, the first stirring tube 303 and the second stirring tube 306 are alternately distributed inside the slurry pretreatment tank 2.

[0027] like Figure 2 As shown, a filter screen 4 is provided on the flow divider plate 304, an exhaust pipe 203 is located above the filter screen 4, and a feed pipe 201 is located below the filter screen 4.

[0028] like Figure 2 As shown, the connecting main pipe 302 is provided with two sections, which are respectively located on the upper and lower sides of the diversion plate 304. The connecting main pipe 302 and the diversion plate 304 are connected internally, and the connecting main pipe 302 located in the upper part extends to the outside of the slurry pretreatment box 2.

[0029] In summary: The stirring component 3 drives the flow divider 304 to rotate, which in turn drives the connecting main pipe 302 and the side stirring plate 305 to rotate around the main shaft of the motor 301, thereby stirring the slurry. During the stirring process, the dosing component 5 and the pressurizing component 6 work to add the chemical solution. Under the action of the pressurizing component 6, high-pressure gas is added into the slurry pretreatment tank 2. Since the chemical solution and the high-pressure gas are in the same flow channel, the chemical solution discharged out through the first stirring pipe 303 and the second stirring pipe 306 is a high-pressure atomized chemical solution, which allows the chemical solution to be sprayed into the slurry more evenly. At the same time, under the turbulence of the gas, the mixing efficiency of the slurry and the chemical solution is further improved. The gas can then be discharged out of the slurry pretreatment tank 2 through the exhaust pipe 203. The filter screen 4 can break up the gas and prevent the slurry from overflowing out through the exhaust pipe 203 in the form of bubbles.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
