[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0025] like Figure 1 , Figure 2 As shown in the figure, this utility model embodiment proposes a coal processing crushing device, including a crushing device feed hopper 1 and a crushing chamber assembly 2. A feed hopper distribution inclined plate 11 is fixedly installed inside the crushing device feed hopper 1. The crushing chamber assembly 2 is fixedly installed below the crushing device feed hopper 1. A drive motor 12 is fixedly installed on the rear surface of the crushing chamber assembly 2. A discharge funnel 8 is integrally provided on the side of the crushing chamber assembly 2. A discharge conveying hose 9 is fixedly connected to the outer end of the discharge funnel 8. A hose self-drain 10 is fixedly installed at the lower end of the discharge conveying hose 9 to connect with external equipment.
[0026] In the above technical solution, the sampled coal briquettes are fed into the feed hopper 1 of the crushing device via a conveyor belt. The feed hopper is then separated by the feed distribution inclined plate 11, which prevents the coal briquettes from getting stuck at the feed inlet. The briquettes are first crushed by the crushing chamber component 2 and then ground into fine powder, which makes it easier to inspect the internal texture of the coal briquettes.
[0027] like Figure 1 , Figures 3 to 5As shown, the crushing chamber assembly 2 includes: a crushing chamber shell 201, a fine grinding shell 202, a crushing roller shaft 203, a carbon block crushing roller 205, a crushing impact roller 206, and a feeding trough 207. The crushing chamber shell 201 is located at the lower end of the feed hopper 1 of the crushing device. The fine grinding shell 202 is integrally formed in the middle of the crushing chamber shell 201. Two carbon block crushing rollers 205 are rotatably mounted on the upper part of the inner wall of the crushing chamber shell 201. The outer ends of the carbon block crushing rollers 205 are coaxially fixedly mounted with crushing roller shafts 203. Several crushing impact rollers 206 are integrally formed on the side of the carbon block crushing rollers 205. A feeding trough 207 is opened on the side of the crushing chamber shell 201 and below the fine grinding shell 202. A crushing impact roller 206 is rotatably mounted inside the fine grinding shell 202. There are two rotating fine grinding discs 209. A fixed fine grinding disc 210 is fixedly installed inside the fine grinding shell 202 and between the two rotating fine grinding discs 209. A fine grinding shaft 204 is fixedly installed coaxially at the outer end of the rotating fine grinding disc 209. A first crushing disc 5 and a second crushing disc 6 are fixedly installed coaxially at the outer ends of the two crushing roller shafts 203, respectively. A first fine grinding disc 3 and a second fine grinding disc 4 are fixedly installed coaxially at the outer ends of the two fine grinding shafts 204, respectively. A rotating belt 7 is sleeved on the first fine grinding disc 3, the second fine grinding disc 4, the first crushing disc 5, and the second crushing disc 6. The output shaft of the drive motor 12 is fixedly connected coaxially to one of the fine grinding shafts 204. A feeding inclined plate 208 is integrally provided on the inner side of the feeding trough 207.
[0028] In the above technical solution, the second fine grinding disc 4 at the front end is driven to rotate by starting the drive motor 12. The second fine grinding disc 4 serves as the drive shaft, and the rotating belt 7 drives the other first fine grinding disc 3, first crushing disc 5 and second crushing disc 6 to rotate. This allows the carbon block crushing roller 205 and the rotating fine grinding disc 209 to rotate synchronously. The crushing and impacting roller 206 on the carbon block crushing roller 205 initially crushes the coal briquettes. The coal briquettes are then ground and pulverized by the alternation between the rotation of the lower rotating fine grinding disc 209 and the middle fixed fine grinding disc 210, which facilitates quality inspection.
[0029] The working principle of this coal processing and crushing device:
[0030] This scheme feeds the sampled coal briquettes into the feed hopper 1 of the crushing device via a conveyor belt. The feed hopper is then separated by the feed distribution inclined plate 11, which prevents the coal briquettes from getting stuck at the feed inlet. The briquettes are first crushed by the crushing chamber component 2 and then ground into fine powder, which makes it easier to inspect the internal texture of the coal briquettes.
[0031] The system drives the second fine grinding disc 4 at the front end to rotate by starting the drive motor 12. The second fine grinding disc 4 serves as the drive shaft, and the rotating belt 7 drives the other first fine grinding disc 3, first crushing disc 5 and second crushing disc 6 to rotate. This allows the carbon block crushing roller 205 and the rotating fine grinding disc 209 to rotate synchronously. The crushing impact roller 206 on the carbon block crushing roller 205 initially crushes the coal briquettes. The coal briquettes are then ground and pulverized by the alternation between the rotation of the lower rotating fine grinding disc 209 and the middle fixed fine grinding disc 210, which facilitates quality inspection.
[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
