Description

Technical Field

[0001] This utility model belongs to the technical field of crushing and granulation equipment, and specifically relates to a granulation device for manufacturing refining slag. Background Technology

[0002] Refining slag refers to a technique in which raw materials are mixed in a certain proportion and particle size, heated at a temperature below the melting point of the raw materials to sinter them together, and then crushed into granular particles for use.

[0003] Existing granulation equipment for refining slag manufacturing, while meeting the basic requirements for crushing refining slag and ensuring thorough crushing through multiple crushing structures, typically proceeds directly to a second crushing process after the first crushing. Since most of the slag has already undergone the first crushing, only a small portion requires secondary crushing. Because this method directly applies secondary crushing to all the slag, the secondary crushing structure wastes a significant amount of time performing ineffective work on slag that doesn't require secondary crushing. This negatively impacts the overall efficiency of slag crushing and granulation, and also leads to ineffective wear of the secondary crushing structure. Therefore, it fails to fully meet user needs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a granulation device for manufacturing refining slag. This device not only meets the basic requirements for crushing and granulating refining slag, but also performs screening on the slag material after initial crushing, thereby only subjecting the small particles that are not completely crushed to secondary crushing, thus improving the overall efficiency of slag material crushing and processing.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a granulation device for manufacturing refining slag, including a crushing box, with a feed cylinder and a discharge cylinder respectively provided at the upper and lower ends of the crushing box. The crushing box is provided with a primary crushing module, a screening module and a secondary crushing module from top to bottom. The screening module includes a screen cylinder that is vertically vibrating and installed inside the crushing box. The crushing box is also provided with a collection hopper located below the primary crushing module and adapted to the screen cylinder. The crushing box is also provided with a spiral sleeve through a horizontal plate. The top of the screen cylinder is provided with a spiral rod that is screwed to the spiral sleeve through a mounting frame. The lower end of the spiral rod is provided with a stirring module. The bottom of the screen cylinder is provided with a discharge pipe adapted to the secondary crushing module. A control valve is provided on the discharge pipe.

[0006] As a further improvement of this utility model, the primary crushing module includes two first mounting shafts rotatably disposed inside the crushing chamber. A first crushing roller is mounted on each first mounting shaft, and a first drive motor is mounted on the crushing chamber. The first drive motor is connected to the first mounting shafts via a first gear transmission assembly. Through the cooperation of the first mounting shafts, the first drive motor, and the first gear transmission assembly, the first crushing roller can be driven to rotate and perform primary crushing of the slag.

[0007] As a further improvement of this utility model, the secondary crushing module includes two second mounting shafts rotatably disposed inside the crushing box. Second crushing rollers are mounted on the second mounting shafts, and a second drive motor is mounted on the crushing box. The second drive motors are connected to the second mounting shafts via a second gear transmission assembly. Through the cooperation of the second mounting shafts, the second drive motors, and the second gear transmission assembly, the second crushing rollers can be driven to rotate and perform secondary crushing of the slag.

[0008] As a further improvement of this utility model, the crushing box is equipped with a support frame located above the secondary crushing module. Multiple springs are vertically arranged on the support frame, and a fixed frame is located at the upper end of each spring. The screen cylinder is placed within the fixed frame, and a vibration motor is mounted on the fixed frame. Through the cooperation of the support frame, multiple springs, fixed frame, and vibration motor, the screen cylinder can be driven to vibrate.

[0009] As a further improvement of this utility model, a guide plate located inside multiple springs is also provided on the support frame, and a guide slot for insertion into the guide plate is provided at the bottom of the fixed frame.

[0010] As a further improvement of this utility model, the stirring module includes a stirring shaft disposed at the lower end of the screw, and stirring blades for stirring the material in the filter cylinder are disposed at the side end of the stirring shaft.

[0011] As a further improvement of this utility model, the bottom of the crushing box is also provided with support legs.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, after the slag is initially crushed by the primary crushing module, it can be screened through a filter cylinder, allowing the fully crushed small particles to be discharged directly. The incompletely crushed slag is intercepted by the filter cylinder and then introduced into the secondary crushing module for secondary crushing. This avoids the secondary crushing module from further crushing the fully crushed slag, thereby improving the overall efficiency of slag crushing and processing.

[0014] Secondly, the insertion and engagement of the guide plate and guide slot not only enables the filter cylinder to vibrate vertically stably, preventing the spring from being damaged by lateral deflection, but also prevents the filter cylinder from causing the screw rod to shift laterally. This allows the screw rod to move vertically stably relative to the screw sleeve and stably drive the screw rod, stirring shaft, and stirring blades to rotate. In addition, since the guide plate and guide slot are sleeved between the side ends of multiple springs and the filter cylinder, it can prevent the slag passing through the filter cylinder from entering the spring and affecting the screening of the slag and the operation of the spring.

Detailed Implementation

[0021] 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.

[0022] like Figure 1 , 2 As shown in Figure 3, a granulation device for manufacturing refining slag includes a crushing box 101. A feed cylinder 102 and a discharge cylinder 103 are respectively installed at the upper and lower ends of the crushing box 101. Inside the crushing box 101, from top to bottom, are a primary crushing module, a screening module, and a secondary crushing module. The screening module includes a vertically vibrating screen cylinder 201 installed inside the crushing box 101. The screen cylinder is offset from the secondary crushing module. Inside the crushing box 101, there is also a collecting hopper 202 located below the primary crushing module and adapted to the screen cylinder 201. Inside the crushing box 101, there is also a hopper 202 located between the collecting hopper 202 and the screen cylinder 201. A horizontal plate 203 is connected between the screen cylinder 201 and the bottom of the horizontal plate 203 is fixedly connected to a spiral sleeve 204. A mounting frame 205 is provided on the top of the screen cylinder 201. A spiral rod 206 is vertically connected to the spiral sleeve 204 and rotated through the mounting frame 205. A bearing 209 is provided on the mounting frame 205. The outer ring of the bearing 209 is fixedly connected to the mounting frame 205. The outer wall of the spiral rod 206 is fixedly connected to the inner ring of the bearing 209. A stirring module is provided at the lower end of the spiral rod 206. A discharge pipe 207 adapted to the secondary crushing module is also provided at the bottom of the screen cylinder 201. A control valve 208 is provided on the discharge pipe 207.

[0023] like Figure 2 , 3 As shown in Figure 4, the crushing box 101 has a support frame 210 located above the secondary crushing module inside. Multiple springs 211 are vertically arranged on the support frame 210, and a fixing frame 212 is located at the upper end of each spring 211. The screen cylinder 201 is disposed within the fixing frame 212, and a vibration motor 213 is mounted on the fixing frame 212. Support legs 104 are also provided at the bottom of the crushing box 101. The support legs 104 provide stable support for the entire device.

[0024] The refining slag enters the equipment through the feed cylinder 102 of the crushing box 101. It first undergoes primary crushing by the primary crushing module, then falls into the collecting hopper 202 and subsequently enters the screen cylinder 201. The screen cylinder 201 screens the slag, allowing the fully crushed small particles to be discharged directly. The screen cylinder 201 intercepts the incompletely crushed slag and then introduces it into the secondary crushing module for secondary crushing. This avoids further crushing of the fully crushed slag by the secondary crushing module, thereby improving the overall efficiency of slag crushing.

[0025] The initially crushed slag falls into the screen cylinder 201. The vibrating motor 213 drives the fixed frame 212 to vibrate. Through the cooperation of the support frame 210 and the spring 211, the screen cylinder 201 vibrates vertically stably. The small particles of slag that are completely crushed pass through the screen holes of the screen cylinder 201 and continue to fall in the crushing box 101, and are discharged through the discharge cylinder 103. The large particles of slag that are not completely crushed are trapped in the screen cylinder 201.

[0026] After a period of time, once a large amount of large particles of slag have been trapped in the screen cylinder 201, the control valve 208 is opened, and the slag is introduced into the secondary crushing module through the discharge pipe 207 for secondary crushing, thereby completing the full crushing of the slag and discharging it through the discharge cylinder 103.

[0027] During the vertical vibration of the filter cylinder 201, which vibrates to screen the slag, the filter cylinder 201 can also drive the mounting frame 205, the screw rod 206, the stirring shaft 216, and the stirring blades 217 to move vertically up and down synchronously. This causes the screw rod 206 to move vertically relative to the screw sleeve 204, and the screw sleeve 204 will drive the screw rod 206 to rotate, thereby driving the stirring shaft 216 and the stirring blades 217 to stir the material in the filter cylinder 201, further improving the screening efficiency and thoroughness.

[0028] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the primary crushing module includes two first mounting shafts 301 rotatably mounted inside a crushing chamber 101. First support bearings 209 are provided at the front and rear ends of the crushing chamber 101. The inner rings of the first support bearings 209 are connected to the side walls of the crushing chamber 101, and the inner rings of the first support bearings 209 are connected to the outer walls of the first mounting shafts 301. A first through hole is also provided on the crushing chamber 101 for rotatable connection with the first mounting shafts 301. A first crushing roller 302 is mounted on the first mounting shafts 301. A first drive motor 303 is mounted on the crushing chamber 101. The first drive motor 303 is connected to the first mounting shafts 301 via a first gear transmission assembly 304. The first drive motor 303 drives the two first mounting shafts 301 to rotate via the first gear transmission assembly 304, thereby driving the first crushing rollers 302 to perform preliminary crushing of the slag.

[0029] According to another embodiment of the present invention, such as Figure 1 , 2As shown, the secondary crushing module includes two second mounting shafts 401 rotatably mounted inside the crushing chamber 101. Second support bearings 209 are provided at the front and rear ends of the crushing chamber 101. The inner rings of the second support bearings 209 are connected to the side walls of the crushing chamber 101, and the inner rings of the second support bearings 209 are connected to the outer walls of the second mounting shafts 401. A second through hole is also provided on the crushing chamber 101, rotatably connected to the second mounting shafts 401. A second crushing roller 402 is mounted on the second mounting shafts 401. A second drive motor 403 is mounted on the crushing chamber 101. The second drive motor 403 is connected to the second mounting shafts 401 via a second gear transmission assembly 404. The second drive motor 403 drives the two second mounting shafts 401 to rotate via the second gear transmission assembly 404, thereby driving the second crushing rollers 402 to perform secondary crushing of large particles of slag.

[0030] According to another embodiment of the present invention, such as Figure 2 As shown, a guide plate 214 is also provided on the support frame 210, located inside the multiple springs 211. The bottom of the fixed frame 212 is provided with a guide slot 215 that engages with the guide plate 214. The vertical engagement of the synchronous guide plate 214 and guide slot 215 not only enables the screen cylinder 201 to vibrate vertically stably, preventing the springs 211 from being damaged by lateral deflection, but also prevents the screen cylinder 201 from causing the screw rod 206 to shift laterally. This allows the screw rod 206 to move vertically stably relative to the screw sleeve 204 and stably drive the screw rod 206, stirring shaft 216, and stirring blades 217 to rotate. In addition, since the guide plate 214 and guide slot 215 are sleeved between the multiple springs 211 and the side ends of the screen cylinder 201, it can prevent the slag passing through the screen cylinder 201 from entering the springs 211 and affecting the screening of the slag and the operation of the springs 211.

[0031] Furthermore, since the guide plate 214 is located on the lower side and the guide slot 215 is located on the upper side, it can effectively prevent slag from entering the guide slot 215 and affecting the subsequent insertion and operation of the guide slot 215 and the guide plate 214.

[0032] According to another embodiment of the present invention, such as Figure 2 , 3 As shown, the stirring module includes a stirring shaft 216 located at the lower end of the screw 206, and stirring blades 217 are provided on the side end of the stirring shaft 216 for stirring the material in the filter cylinder 201.

[0033] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
