It should be noted that in the following implementation, the terms "above", "below", "left side", "right side", "top" and "bottom" do not represent an absolute distinction in structure and / or function, but are only for the convenience of description.

[0022] This embodiment relates to a coke strength measurement drum 21, such as Figure 1 and Figure 2 As shown, it includes a loading and lifting mechanism 1, a rotating measuring mechanism 2, and a discharging and screening mechanism 3. The loading and lifting mechanism 1 includes a lifting motor 11, a lifting chain 12, a lifting bucket 13 and a lifting wheel 14; the rotating measuring mechanism 2 is composed of a drum 21 and a drum self-rotation component 22, and the drum self-rotation component 22 includes a self-rotation motor, a first bracket and a roller mechanism; the discharging and screening mechanism 3 includes a drum turning component 31 and a screen plate component 32, and the drum turning component 31 includes a turning motor, a second bracket and a sprocket mechanism, and the screen plate component 32 is composed of two screen plates placed in succession in the horizontal direction; below the screen plate component 32 is a receiving hopper, and below the receiving hopper is a receiving box with a pulley.

[0023] like Figure 3As shown, the loading and lifting mechanism 1 includes a lifting motor 11, a lifting chain 12, a lifting bucket 13 and a lifting wheel 14, which are used to lift the raw coke material from a low place to a high place and pour it into the drum 21. The lifting motor 11 forms a chain transmission with the lifting chain 12 through the lifting wheel 14. The lifting wheel 14 is fixed to the lifting chain 12 with a fixing pin or a fixing bolt. The discharge port of the lifting bucket 13 corresponds exactly to the discharge port of the drum 21, so that when the lifting bucket 13 moves to the discharge position, the coke can be poured into the drum 21.

[0024] like Figure 2 As shown, the rotary measuring mechanism 2 is composed of a drum 21 and a drum self-rotating assembly 22. The drum 21 has a circular material opening, and one side of the material opening has a drum circumferential panel for easy cooperation with the roller, thus forming a rotating circumferential surface; the drum circumferential panel includes a cylindrical surface and a conical surface, wherein the material opening is arranged on the conical surface, and the cylindrical surface contacts and cooperates with the roller. There is a fixed plate on the opposite side of the material opening, so that the self-rotating motor can drive the drum 21 to rotate at the fixed plate position through chain transmission. The drum self-rotating assembly 22 includes a self-rotating motor, a first bracket and a roller mechanism. The first bracket in the drum self-rotating assembly 22 is used to fix the self-rotating motor and the roller mechanism. The roller mechanism includes eight rollers arranged in various directions of the drum 21. When the self-rotating motor rotates, it will drive each roller to roll and thus support the drum 21 to rotate.

[0025] The unloading screening mechanism 3 includes a drum turning assembly 31 and a screen plate assembly 32. The drum turning assembly 31 includes a turning motor, a second bracket and a sprocket mechanism. The turning motor 31 is used to drive the drum 21 to turn over, so as to adjust the direction and position of feeding and unloading. The second bracket in the drum turning assembly 31 is used to fix the turning motor and the sprocket mechanism. The sprocket mechanism includes a main sprocket, a slave sprocket and a chain. The main sprocket cooperates with the slave sprocket through the chain. The slave sprocket is hung on the first bracket. The turning motor drives the main sprocket to drive the slave sprocket to rotate, thereby driving the first bracket to turn over. The screen plate assembly 32 is located below the drum 21 and is composed of two sieve plates placed in succession in the horizontal direction. The sieve plate is a straight sieve plate. A number of meshes are evenly and evenly opened on the surface of the sieve plate, including a fine mesh sieve plate on the left and a coarse mesh sieve plate on the right. The coke screened by the fine mesh sieve plate falls into the first receiving hopper 41 below, and the coke screened by the coarse mesh sieve plate falls into the second receiving hopper 42 below. Shock absorbers are arranged on both sides of the screening mechanism to reduce the noise generated by the collision between the coke and the shell during the screening process.

[0026] The specific working process of the coke drum 21 of this embodiment is as follows: first, prepare a batch of coke raw materials, put them into the lifting bucket 13, and the lifting motor 11 drives the lifting chain 12 to drive the lifting bucket 13 to rise. After rising to the highest point, the lifting bucket 13 tilts downward to pour the coke raw materials into the drum 21. The drum self-rotating component 22 starts to control the drum 21 to rotate, so that the coke raw materials are fully extruded and wear-resistant. During this process, the coke that does not meet the quality standards will be squeezed to break or crush, and the qualified coke will basically keep its original shape. After a specified period of testing, the drum flipping component 31 starts to control the drum 21 to flip, unload the coke in the drum 21 and drop it onto the sieve plate component 32 below. The coke that is broken due to the test will slide through the fine mesh sieve plate to the first receiving hopper 41 below, and the coke that remains in its original shape will slide through the coarse mesh sieve plate to the second receiving hopper 42 below, thereby distinguishing the coke with qualified strength from the unqualified coke.

[0027] It should be noted that the scheme described in the embodiments of the present application is only one of the implementation methods. Simple modifications made on this basis should be regarded as ordinary technicians in this field being inspired by the present application. Without departing from the inventive purpose of the present utility model, they can creatively design structural methods and embodiments similar to the technical scheme, which should all fall within the scope of protection of the present utility model.
