Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0024] Reference Figures 1-4 A crushing device for producing spheroidizing agents with multi-stage crushing function includes a crushing unit, a screening unit, a collection unit, and a recovery unit. The crushing unit includes a primary crushing unit and a secondary crushing unit. The primary crushing unit includes a primary crushing chamber 7, in which a mounting frame 14 is installed. Crushing rollers 4 are installed in the mounting frame 14. A first drive motor 8 is installed at one end of one of the crushing rollers 4. The crushing rollers 4 are covered with a tungsten carbide wear-resistant layer, which is mainly used to protect the crushing rollers 4 and extend their service life. A limit groove 13 is provided on the mounting frame 14. A moving block 12 is slidably connected in the limit groove 13. A bearing 11 is installed between the moving block 12 and the crushing rollers 4. A hydraulic cylinder 9 is provided on one side of the moving block 12.

[0025] First, adjust the distance between the crushing rollers 4 according to the size of the batch of spheroidizing agent. Then, use the hydraulic cylinder 9 to drive the moving block 12 to move slowly, thereby moving one of the crushing rollers 4 connected to it to the other, thus changing the distance between the crushing rollers 4. After the distance is determined, start the first drive motor 8 to drive one of the crushing rollers 4 to rotate, and then transport the spheroidizing agent material into the primary crushing chamber 7 to start coarse crushing. The distance between the crushing rollers 4 in the primary crushing can be adjusted according to the volume of the batch of spheroidizing agent to accelerate the crushing effect.

[0026] An inclined limiting block 5 is provided in the primary crushing chamber 7. The lower end of the limiting block 5 is located between the crushing rollers 4. This setting can ensure that the spheroidizing agent material falls into the crushing rollers 4 after entering from the primary crushing chamber 7.

[0027] The secondary crushing unit includes a secondary crushing chamber 1 connected to the primary crushing chamber 7. An impact plate 17 is installed inside the secondary crushing chamber 1. An installation shaft is inserted at the center of the impact plate 17. A second transmission wheel is fixedly connected to one end of the installation shaft. The second transmission wheel is connected to a first transmission wheel 15 through a transmission belt 10. A second drive motor 3 is installed at one end of the first transmission wheel 15 on the upper surface of the secondary crushing chamber 1. The second drive motor 3 drives the first transmission wheel 15 to rotate, which in turn drives the second transmission wheel to rotate through the transmission belt 10, thereby driving the impact plate 17 to rotate. The rotation speed of the impact plate 17 is at least 1800 r / min. During rotation, the spheroidizing agent is crushed by impact through centrifugal force.

[0028] The collection unit includes a collection chamber 2 located below the secondary crushing chamber 1. The collection chamber 2 is used to collect the crushed finished product to facilitate subsequent processes.

[0029] The screening unit includes an inclined screen 16 located below the impact plate 17. After secondary crushing, the spheroidizing agent is screened through the screen 16. The qualified material enters the collection bin 2, while the unqualified material enters the recycling unit.

[0030] The secondary crushing chamber 1 is equipped with a return feed inlet and a recovery discharge outlet. The recovery unit includes a screw conveyor 6. The upper and lower ends of the screw conveyor 6 are connected to the return feed inlet and the recovery discharge outlet, respectively. Items that do not pass through the screen 16 will enter the screw conveyor 6 and then be recovered into the secondary crushing chamber 1 for further crushing until the particle diameter is qualified.

[0031] By connecting the primary and secondary crushing units in series, work efficiency is greatly improved.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
