Description

Technical Field

[0001] This utility model belongs to the field of dust treatment technology, and specifically relates to a dust treatment device for pre-melted slag. Background Technology

[0002] The processing of pre-melted slag generates a large amount of dust. To avoid environmental pollution, dust treatment equipment is needed to remove the generated dust. While existing dust treatment equipment for pre-melted slag can meet the basic requirements for dust removal, it typically uses a linear mixing structure to mix the liquid and dust. Dust tends to pass through the mixing structure quickly along a straight path, resulting in a short mixing time and poor mixing efficiency. Consequently, the dust cannot be fully mixed, which also affects the dust removal effect.

[0003] For example, the utility model patent with announcement number CN217188569U discloses an electroslag premelted slag dust treatment device. In the technical solution of this patent document, the liquid material and dust enter the mixing tube from the upper two sides of the mixing tube respectively, and then leave from the lower side of the mixing tube quickly along a straight path, resulting in poor mixing and treatment effect of dust, which cannot fully meet people's needs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a dust treatment device for pre-melted slag, which not only meets the basic requirements for dust treatment but also significantly extends the mixing path and mixing time of dust in the mixing structure, thereby improving the mixing and treatment effect of dust and thus more fully meeting people's usage needs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a dust treatment device for pre-melted slag, including a treatment box, a serpentine treatment pipe is arranged inside the treatment box, and a stirring shaft is rotatably arranged on the top and bottom walls of the treatment box and a plurality of vertical sections of the treatment pipe, with stirring blades arranged on the stirring shafts. A liquid inlet pipe and an air inlet pipe are arranged on the treatment box and connected to one end of the treatment pipe. A first control valve is arranged on the liquid inlet pipe. A discharge port inserted into the liquid is arranged at the other end of the treatment pipe. An exhaust pipe is arranged on the top of the treatment box and a drain pipe is arranged at the bottom of the treatment box. A second control valve is arranged on the drain pipe.

[0006] As a further improvement of this utility model, a drive motor with an output shaft extending into the interior of the processing box is vertically arranged on the top of the processing box. A drive gear is arranged on the output shaft of the drive motor, and multiple driven gears are respectively arranged on multiple stirring shafts, with the outermost driven gear also meshing with the drive gear. Through the cooperation of the drive motor, the drive gear, and multiple driven gears, multiple stirring shafts can be rotated.

[0007] As a further improvement of this utility model, a connecting rod is provided on the inner side wall of the processing box to connect with the processing tube. The processing tube can be fixed to the inside of the processing box by means of the connecting rod.

[0008] As a further improvement of this utility model, the lower end of the processing box is conical.

[0009] As a further improvement of this utility model, the front end of the processing box is detachably provided with a box cover.

[0010] As a further improvement of this utility model, the processing tube includes a first half-tube body connected to the connecting plate and the stirring shaft, and a second half-tube body detachably connected to the first half-tube body.

[0011] As a further improvement of this utility model, the processing box is also provided with a transparent observation window.

[0012] As a further improvement of this utility model, the bottom of the processing box is also provided with support legs.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Firstly, dust can enter one side of the treatment pipe through the air inlet pipe, and liquid can enter the other side of the treatment pipe through the liquid inlet pipe, filling the treatment pipe completely and submerging it. This allows the dust to flow in the serpentine treatment pipe, extending the mixing path between the dust and the liquid. Furthermore, multiple stirring shafts and blades can agitate and mix the liquid and dust, ensuring more thorough mixing and more effective dust removal.

[0015] Secondly, by first separating the lid from the processing box and then separating the second half of the tube from the first half, the first and second half of the tube can be easily cleaned. Attached Figure Description

Detailed Implementation

[0023] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0024] like Figure 1 , 3 As shown in Figures 4 and 5, a dust treatment device for pre-melted slag includes a treatment box 101. The interior of the treatment box 101 is provided with a serpentine treatment tube 102. The top and bottom walls of the treatment box 101 are respectively provided with stirring shafts 103 that are rotatably connected to multiple vertical parts of the treatment tube 102 via bearings 114. The outer ring of the bearing 114 is connected to the top wall of the vertical part of the treatment box 101, and the inner ring of the bearing 114 is connected to the upper outer wall of the stirring shaft 103. The stirring shaft 103 is also rotatably connected to the upper end of the treatment tube 102.

[0025] A stirring blade 104 is provided on the stirring shaft 103. A liquid inlet pipe 105 and an air inlet pipe 106 are provided on the processing tank 101, both connected to one end of the processing pipe 102. A first control valve 107 is provided on the liquid inlet pipe 105. A discharge port 108, which is inserted into the liquid, is provided at the other end of the processing pipe 102. An exhaust pipe 109 is provided at the top of the processing tank 101, and a drain pipe 110 is provided at the bottom of the processing tank 101. A second control valve 111 is provided on the drain pipe 110. A connecting rod 112, connected to the processing pipe 102, is provided on the inner wall of the processing tank 101.

[0026] like Figure 4 , 5 As shown, the top of the processing box 101 is also vertically provided with a drive motor 201 whose output shaft extends into the processing box 101. The output shaft of the drive motor 201 is provided with a drive gear 202, and multiple stirring shafts 103 are respectively provided with mutually meshing driven gears 203. The outermost driven gear 203 also meshes with the drive gear 202.

[0027] Workers can first open the first control valve 107 and introduce liquid (such as water or other liquid) into one end of the processing pipe 102 through the liquid inlet pipe 105, filling the processing pipe 102 and allowing the liquid to enter the processing tank 101 through the processing pipe 102 until the processing pipe 102 is submerged. Then the first control valve 107 can be closed to prevent gas from entering the liquid inlet pipe 105.

[0028] Subsequently, the dust-containing gas can be introduced into one end of the serpentine treatment tube 102 inside the treatment box 101 through the air inlet pipe 106. The dust flows in the serpentine treatment tube 102, extending its contact and mixing path with the liquid and the mixing time. At the same time, the stirring shaft 103 can be driven to rotate. Through the rotation of the stirring shaft 103 and the stirring blades 104, the liquid and dust are agitated, so that the dust can be more fully mixed with the liquid, thereby achieving a more efficient dust removal effect.

[0029] The treated gas is discharged from the outlet of the treatment pipe 102, and the liquid material entering the treatment box 101 is further mixed and treated before being discharged from the treatment box 101 through the exhaust pipe 109. At this point, most of the dust in the gas has been captured and settled in the liquid material.

[0030] During the processing, the dust-laden liquid gradually settles to the bottom of the processing tank and processing box 101. When it is necessary to clean or replace the liquid, the second control valve 111 on the drain pipe 110 is opened to discharge the dust-laden liquid. At the same time, the first control valve 107 can be opened again to introduce new liquid into the processing pipe 102 through the inlet pipe 105, thereby replacing the liquid in the processing pipe 102 and discharging the sediment from the processing pipe 102. Then, the sediment is discharged from the processing box 101 through the outlet pipe. After that, the second control valve 111 is closed, allowing the liquid to submerge the processing pipe 102 again.

[0031] When the equipment needs to be cleaned, the cover 301 at the front end of the processing box 101 can be removed first, and then the second half of the processing tube 102 can be separated from the first half of the processing tube to facilitate cleaning of the inside of the processing tube 102 and the stirring shaft 103; after cleaning, the equipment can be reassembled.

[0032] According to another embodiment of the present invention, such as Figure 1 , 3 As shown, the lower end of the processing tank 101 is conical, which allows for more thorough drainage of the liquid material from the processing tank 101.

[0033] According to another embodiment of the present invention, such as Figure 1 , 2 As shown in Figure 3, the front end of the processing box 101 is detachably provided with a box cover 301. The front end of the processing box 101 is provided with a mounting hole 302, and the box cover 301 is engaged with the mounting hole 302. A sealing ring 303 is also provided on the inner side wall of the box cover 301. A fastening bolt 304 for screwing into the processing box 101 is also provided on the box cover 301. A threaded fastening hole for screwing into the fastening bolt 304 is provided on the processing box 101. A handle 306 is provided on the box cover 301. Simply separate the fastening bolt 304 from the threaded fixing hole, release the fixing at the connection between the treatment box 101 and the box cover 301, and separate the box cover 301 and the sealing ring 303 from the mounting hole 302, and the box cover 301 can be removed; then the box cover 301 and the sealing ring 303 can be engaged with the mounting hole 302, and the fastening bolt 304 can be passed through the box cover 301 and screwed into the threaded fastening hole, and the box cover 301 can be reinstalled on the treatment box 101.

[0034] According to another embodiment of this utility model, the processing tube 102 includes a first half-tube body connected to the connecting plate and the stirring shaft 103, and a second half-tube body snapped into the first half-tube body. The first half-tube body is provided with a connecting groove, and the second half-tube body is provided with a connecting plate snapping into the connecting groove. The first half-tube body is provided with a first connecting plate, and the second half-tube body is provided with a second connecting plate. The second connecting plate is also provided with a connecting bolt for screwing into the first connecting plate. The first connecting plate has a threaded connection hole for screwing into the second connecting plate. By simply separating the fastening bolt 304 from the threaded fastening hole and then separating the connecting plate from the connecting groove, the second half-tube body can be removed from the second half-tube body. Similarly, by simply snapping the connecting groove into the connecting plate and then passing the connecting bolt through the second connecting plate and screwing it into the threaded connection hole, the first half-tube body can be flexibly fixed to the first half-tube body.

[0035] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the processing box 101 is also equipped with a transparent observation window 305. The transparent observation window 305 facilitates real-time monitoring of the processing process.

[0036] According to another embodiment of the present invention, such as Figure 1 As shown, the bottom of the processing box 101 is also provided with support legs 113 to ensure the stability of the equipment during operation.

[0037] The above description is the preferred embodiment of this utility model.
