Its properties are similar to those of desulfurizers, making it suitable for use as a desulfurizer. Through crushing, grinding, grading, and drying processes, white mud is transformed into a relatively fine powder.

[0003] At present, white mud is mainly used in wet desulfurization in the desulfurization process. In this process, white mud needs to be mixed with water to form white mud slurry before it can be used. At present, in order to prepare white mud slurry, it is usually necessary to use white mud slurrying equipment. However, the current white mud slurrying equipment generally adopts the form of slurrying tank and mixer.

DETAILED DESCRIPTION

[0029] The white mud comprehensive utilization device of the present invention is a white mud pulping device integrating the functions of material storage, material conveying, water storage, water conveying, mixing and dust removal.

[0030] Example:

[0031] like Figures 1 to 4 As shown, in order to solve the above problems, the present embodiment discloses a white mud comprehensive utilization device, including a mounting assembly 10, a storage hopper 20, a stirring tank 30, a liquid storage tank 40 and a dust collector 50. The storage hopper 20, the stirring tank 30, the liquid storage tank 40 and the dust collector 50 are cooperatively arranged on the mounting assembly 10. The storage hopper 20 is connected to the stirring tank 30 through an auger conveyor 60, and the liquid storage tank 40 is connected to the stirring tank 30 through a water injection pipe 400.

[0032] A shielding assembly is provided on the top of the storage funnel 20, which includes a cover plate 200, a powder leakage plate 201, a dust shield frame 202, and a dust shield frame door 203. The cover plate 200 is provided on the top of the storage funnel 20, and a material inlet pipe 204 is provided at one end of the cover plate 200. The powder leakage plate 201 is provided on the top of the material inlet pipe 204. The dust shield frame 202 is provided on the powder leakage plate 201. The dust shield frame door 203 is provided on the dust shield frame 202 and is rotatably connected to the dust shield frame 202.

[0034] During use, when the operator pours the white mud powder into the dust shield frame 202, the white mud powder enters the material inlet pipe 204 from the feed hole 205, and then enters the storage hopper 20. During this process, the flying white mud powder is sucked into the dust collector 50 by the dust collector 50 and the dust removal pipe 500, which can effectively avoid the problem of the white mud powder scattering. By providing the dust shield frame door 203, when the white mud powder in the storage hopper 20 is sufficient, the dust shield frame door 203 is pulled down to further avoid the white mud powder from flying and scattering. By connecting the storage hopper 20 and the mixing tank 30 through the auger conveyor 60, the white mud powder can be effectively avoided from flying and scattering when adding water for stirring. This solves the problem that the white mud powder is easily scattered everywhere when pouring white mud powder or adding water for stirring in the white mud powder in the current white mud pulping equipment, causing a bad working environment.

[0035] The setting of the powder leakage plate 201 can effectively prevent the container containing white mud powder from falling into the storage funnel.

[0036] The stirring tank 30, the dust remover 50 and the auger conveyor 60 can all adopt existing technology. Wherein, the stirring tank 30 can also adopt the following structure.

The flow control valve 303 and the first ball valve 405 can be used to transport the water in the mixing tank 30 and control the flow of water, thereby achieving the purpose of regulating and controlling the water content in the white mud slurry.

[0043] like Figure 4 As shown, in order to facilitate the addition and discharge of water in the liquid storage tank 40, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a water supply pipe 401 is provided on the liquid storage tank 40, a second ball valve 402 is provided on the water supply pipe 401, a drain pipe 403 is provided at the lower end of the liquid storage tank 40, a third ball valve 404 is provided on the drain pipe 403, and a liquid level gauge is provided on the liquid storage tank 40.

[0044] The second ball valve 402 and the third ball valve 404 may be electric ball valves or manual ball valves in the prior art, and the liquid level gauge may be an electronic liquid level gauge in the prior art.

[0045] like Figure 2 As shown, in order to facilitate the installation of the present invention and the subsequent addition of white mud powder, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the mounting assembly 10 includes a mounting base plate 100, a mounting top plate 101 and a plurality of support arms 102, and the plurality of support arms 102 are arranged between the mounting base plate 100 and the mounting top plate 101. The two ends of the plurality of support arms 102 are fixedly connected to the mounting base plate 100 and the mounting top plate 101 respectively, and a matching window 103 is provided on the mounting top plate 101.

[0046] Among them, a first bracket 104 is set on the mounting base 100, the bottom of the first bracket 104 is fixedly connected to the mounting base 100, the top of the first bracket 104 extends from the matching window 103 to above the mounting top plate 101, and the storage funnel 20 is fixedly set on the top of the first bracket 104.

[0047] The first bracket 104 is located on one side of the mixing tank 30 .

[0048] When in use, the setting of the first bracket 104 can facilitate the installation of the storage funnel 20, and at the same time extend the storage funnel 20 to above the installation top plate 101, making it convenient for operators to add white mud powder.

[0049] like Figure 2 As shown, the first bracket 104 is provided with a mounting frame 105 which is arranged in conjunction with the auger conveyor 60, and one end of the auger conveyor 60 is fixedly connected to the mounting frame 105.

[0050] The auger conveyor 60 is arranged at an angle, and the end connected to the mounting frame 105 is the lower end.

[0051] When in use, the arrangement of the mounting frame 105 and the fixing frame 106 facilitates the installation of the auger conveyor 60, and facilitates the transportation of the white mud powder from the storage hopper 20 to the mixing tank 30. At the same time, the auger conveyor 60 can also break up the accumulated white mud powder.

[0052] A plurality of suspension brackets 107 are provided at the bottom of the mounting top plate 101 , and a connecting seat 406 which cooperates with the suspension bracket 107 is provided on the liquid storage tank 40 , and the connecting seat 406 is fixedly connected to the suspension bracket 107 .

[0053] When in use, the setting of the hanging bracket 107 and the connecting seat 406 can facilitate the installation of the liquid storage tank 40. At the same time, since the liquid storage tank 40 is suspended, the height of the liquid storage tank 40 can be set above the stirring tank 30, so that the water in the liquid storage tank 40 can be injected into the stirring tank 30 by relying on gravity, which can reduce some construction costs.

[0054] like Figure 3 As shown, in one embodiment, the number of suspension brackets 107 is 3, and the number of connecting seats 406 is 3. The connecting seats 406 are arranged on the outside of the liquid storage tank 40 and are fixedly connected to the liquid storage tank 40.

[0057] Working principle of this utility model:

[0058] During use, when the operator pours the white mud powder into the dust shield frame 202, the white mud powder enters the material inlet pipe 204 from the discharge hole 205, and then enters the storage funnel 20. In this process, the flying white mud powder is sucked into the dust collector 50 and the dust removal pipe 500 by the dust collector 50, which can effectively avoid the problem of white mud powder scattering; by setting the dust shield frame door 203, when the white mud powder in the storage funnel 20 is sufficient, the dust shield frame door 203 is pulled down to further avoid the white mud powder from flying and scattering; by connecting the storage funnel 20 and the mixing tank 30 through the auger conveyor 60, the white mud powder can be effectively avoided from flying and scattering when adding water and stirring.

[0059] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
