DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments.

[0024] Example:

[0025] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0026] A slag granulation device comprises a base 1, a screening assembly 2 is arranged on the top of the base 1, a support frame 3 is arranged on the top of the base 1 and behind the screening assembly 2, and a feed hopper 4 is arranged on the top of the screening assembly 2 and the support frame 3;

[0027] Among them, a feed hopper 4 is provided on the top of the screening assembly 2 and the support frame 3, and the feed hopper 4 is used to crush and granulate the slag;

[0028] Two groups of crushing rollers 401 are rotatably connected inside the feed hopper 4, and a number of crushing blades 402 are fixedly connected to the outside of the two groups of crushing rollers 401. The several crushing blades 402 are all designed in a cross structure. A driving mechanism 403 is installed on the top of the support frame 3 and at a position corresponding to the two groups of crushing rollers 401. The driving mechanism 403 penetrates the feed hopper 4 and is fixedly connected to the crushing rollers 401. An inclined discharge plate 101 is fixedly connected inside the base 1.

[0029] Specifically, firstly, the base 1 is placed at the designated position, and the slag to be processed is poured into the feed hopper 4, and the two sets of crushing rollers 401 are driven to rotate by the driving mechanism 403. At this time, the support frame 3 supports the driving mechanism 403, and then the crushing rollers 401 drive the crushing blades 402 to fight, and then the crushing blades 402 crush the slag, and the crushed slag falls into the screening component 2, and the granulated slag is filtered and screened by the screening component 2, and the slag that does not meet the granulation standard is screened out, which is convenient for the user to process it again, thereby improving the granulation quality.

[0030] Also, see Figure 1-Figure 4 , a screening assembly 2 is provided on the top of the base 1;

[0031] The screening component 2 is used to filter and screen the crushed slag. The specific structure of the screening component 2 is as follows:

[0032] The screening assembly 2 includes a quantitative box 201, a material discharge baffle 202, a rotating frame 203, a rotating column 204, a rotating groove 205, a material discharge pressure plate 206, a sliding block 207, a sliding groove 208, a buffer spring 209, a pressure sensor 210, a telescopic cylinder 211, a movable plate 212 and a filter hole 213. The quantitative box 201 is fixedly connected to the inside of the base 1, and a material discharge baffle 202 is provided on the back of the base 1. The rotating frame 203 is fixedly connected to the back of the material discharge baffle 202 and located on the inner side of the quantitative box 201. The rotating column 204 is fixedly connected to the inside of the quantitative box 201 and located at a corresponding position of the rotating frame 203. The rotating frame 203 is provided with a rotating groove 205 inside. The internal structure size of the rotating groove 205 is set corresponding to the external structure size of the rotating column 204. The interior of 201 is slidably connected with a material discharge plate 206, and two groups of sliding blocks 207 are fixedly connected to the left and right sides of the material discharge plate 206. Sliding grooves 208 are provided inside the metering box 201 and at positions corresponding to the four groups of sliding blocks 207. Buffer springs 209 are fixedly connected inside the four groups of sliding grooves 208. A pressure sensor 210 is provided inside the metering box 201 and below the material discharge plate 206. The top of the material discharge plate 206 is designed with an inclined structure. The left and right sides of the metering box 201 are fixedly connected with telescopic cylinders 211. The two groups of telescopic cylinders 211 are respectively connected to two groups of moving plates 212 through two groups of hinge seats. The two groups of moving plates 212 are respectively fixedly connected to the left and right sides of the material discharge baffle 202. A number of filter holes 213 are provided inside the material discharge plate 206.

[0033] Specifically, the crushed granulated slag is screened and filtered by the screening component 2, and the granulated slag is poured into the quantitative box 201, and the granulated slag is accumulated on the feed pressing plate 206. The smaller granulated slag falls into the base 1 through the filtering hole 213, and falls out through the inclined feed plate 101 in the base 1. The larger granulated slag squeezes the feed pressing plate 206, and reaches the sliding block 207 through the feed pressing plate 206 to move in the sliding groove 208, and squeezes the buffer spring 209 in the sliding groove 208 through the sliding block 207, so that the buffer spring 209 enters a contracted state. When the weight of the granulated slag reaches the standard, the feed pressing plate 206 is squeezed onto the pressure sensor 210. The pressure sensor 210 transmits the signal to the controller after being sensed, and is started by the controller. The two sets of telescopic cylinders 211 are driven, and the two sets of movable plates 212 are fixedly connected to the left and right sides of the unloading baffle 202 respectively. The two sets of telescopic cylinders 211 drive the two sets of movable plates 212 to move through the two sets of hinge seats respectively, and drive the unloading baffle 202 to move through the movable plates 212. The internal structure size of the rotating groove 205 is set corresponding to the external structure size of the rotating column 204. At this time, the unloading baffle 202 is engaged with the rotating column 204 through the rotating frame 203, and the unloading baffle 202 is rotated through the rotating frame 203 and the rotating column 204, so that the bottom of the unloading baffle 202 is removed from the quantitative box 201, so that the granulated slag falls out of the quantitative box 201 from the unloading pressure plate 206, and then the slag that does not meet the granulation standard is granulated again, thereby improving the granulation quality.

[0034] In this embodiment, the implementation scenario is specifically as follows: in actual use, first place the base 1 at the designated position, pour the slag to be processed into the feed hopper 4, and drive the two sets of crushing rollers 401 to rotate through the driving mechanism 403. At this time, the support frame 3 supports the driving mechanism 403, and then drives the crushing blades 402 to fight through the crushing rollers 401, and then the slag is crushed by the crushing blades 402. The crushed slag falls into the screening component 2, and the granulated slag is filtered and screened by the screening component 2, and the slag that does not meet the granulation standard is screened out, which is convenient for the user to process it again, thereby improving the granulation quality. Compared with the existing slag granulation device, the utility model can improve the overall practicality of the slag granulation device through design.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
