Description

Technical Field

[0001] This utility model relates to the field of coke production technology, and in particular to a screening device for coke production. Background Technology

[0002] Shaped coke is a special type of coke product with significant applications in industrial production. During its production, the raw materials need to be screened using inclined screens. When a loader delivers the raw materials to the screen, if the loader dumps the materials quickly, the screen cannot screen them in time; if the materials are dumped slowly, the loader must remain at the screen for an extended period. Therefore, designing a screening device for shaped coke production is essential. Summary of the Invention

[0003] The purpose of this application is to provide a screening device for coke production.

[0004] To achieve the above objectives, this application provides the following technical solution: a screening device for coke production, comprising a frame, a track horizontally fixed on the frame, an electric traveling trolley mounted on the track, the electric traveling trolley being fixedly connected to an intermediate hopper box via a crossbeam, a plurality of partitions vertically fixed inside the intermediate hopper box, the partitions dividing the intermediate hopper box into multiple buffer chambers, each buffer chamber having an output port at its bottom, an electric control plate installed at the output port, the electric control plate being able to close the output port, and a screen arranged at an angle below the intermediate hopper box.

[0005] An upper connecting shaft is fixed at the upper end of the screen, and the upper connecting shaft is movably connected to an annular groove plate. The annular groove plate is fixed to the frame by a fixing plate. A lower connecting shaft is fixed at the lower end of the screen, and the lower connecting shaft is rotatably connected to an upper fixed seat. The upper fixed seat is connected to the lower fixed seat by two springs. The lower fixed seat is fixedly connected to an adjusting block. The slider of the adjusting block is connected to a guide post. The guide post is also fixedly connected to a mounting base. A fastening bolt is threaded onto the adjusting block.

[0006] A vibration motor is also installed at the lower end of the screen.

[0007] A limiting disc is also fixed on the upper connecting shaft.

[0008] A limit head is also fixed on the guide post.

[0009] In summary, the technical effects and advantages of this utility model are as follows: In this invention, a forklift is used to feed coke raw materials into an intermediate hopper. An electric trolley moves the intermediate hopper, and once the foremost buffer chamber is directly above the screen, the corresponding electric control plate is flipped downwards. The coke raw materials in this buffer chamber fall onto the screen for screening. After screening, the electric trolley moves the intermediate hopper forward, causing the coke raw materials in the next buffer chamber to fall onto the screen. In this way, the coke raw materials brought by the forklift can be poured onto the screen in batches, which avoids pouring too much coke raw material onto the screen at once and allows the forklift to quickly dump the coke raw materials out.

[0012] 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.

[0013] like Figures 1-5As shown, this type of screening device for coke production includes a frame 1, a track 2 horizontally fixed on the frame 1, an electric traveling vehicle 3 mounted on the track 2, the electric traveling vehicle 3 is an existing tractor vehicle, which can travel on the track 2; the electric traveling vehicle 3 is fixedly connected to the intermediate hopper box 4 through a crossbeam 8, several partitions 9 are vertically fixed inside the intermediate hopper box 4, and the partitions 9 divide the intermediate hopper box 4 into multiple buffer chambers 4a, each buffer chamber 4a has an output port at the bottom, and an electric control plate 10 is installed at the output port, the electric control plate 10 adopts an existing structure, which can be opened or closed as needed; and the electric control plate 10 can close the output port, and a screen 6 is arranged below the intermediate hopper box 4, and the screen 6 is arranged at an angle.

[0014] The upper end of the screen 6 is fixed with an upper connecting shaft 11, which is movably connected to an annular groove plate 17. The annular groove plate 17 is fixed to the frame 1 by a fixing plate 5. The lower end of the screen 6 is fixed with a lower connecting shaft 13, which is rotatably connected to an upper fixed seat 14. The upper fixed seat 14 is connected to the lower fixed seat 16 by two springs 15. The lower fixed seat 16 is fixedly connected to an adjusting block 20. The slider of the adjusting block 20 is connected to a guide post 21. The guide post 21 is also fixedly connected to a mounting seat 22. A fastening bolt 19 is threaded onto the adjusting block 20. With this structure, the tilt angle of the screen 6 can be adjusted by adjusting the position of the adjusting block 20 on the guide post 21. A vibration motor 7 is also installed at the lower end of the screen 6. With this structure, the screen 6 can produce a certain vibration effect through the vibration motor 7.

[0015] In practice, both frame 1 and mounting base 22 are fixed to the ground using existing methods.

[0016] A limiting disc 12 is also fixed on the upper connecting shaft 11. This structure can prevent the upper connecting shaft 11 from detaching from the annular groove plate 17.

[0017] A limit head 18 is also fixed on the guide column 21.

[0018] In this invention, a forklift is used to load coke raw materials into the intermediate hopper box 4. An electric traveling vehicle 3 drives the intermediate hopper box 4 to move. Once the foremost buffer chamber 4a is directly above the screen 6, the corresponding electric control plate 10 is operated to flip downwards. The coke raw materials in the buffer chamber 4a will fall onto the screen 6 for screening. After the screening is completed, the electric traveling vehicle 3 drives the intermediate hopper box 4 to continue moving forward, so that the coke raw materials in the next buffer chamber 4a fall onto the screen 6. In this way, the coke raw materials transported by the forklift can be poured onto the screen 6 in batches, which not only avoids pouring too much coke raw materials onto the screen 6 at one time, but also allows the forklift to quickly pour out the coke raw materials.
