Technical Field

[0001] This utility model relates to the field of coking coal processing technology, specifically to a coking coal screening mechanism. Background Technology

[0002] Coking coal is a type of bituminous coal that has a certain degree of caking properties and can coke under coking conditions in a chamber coke oven. It is used as raw material for producing a certain quality of coke. As the name suggests, coking coal is mainly used for coke production. It is usually classified according to its use into metallurgical coke (including blast furnace coke, foundry coke, and ferroalloy coke), gasification coke, and coke for calcium carbide.

[0003] In the process of re-processing coking coal, screening mechanisms are usually used to screen the coking coal raw material particles in order to separate the smaller particles and prevent the raw materials of different sizes from being mixed together, which would affect the subsequent processing quality.

[0004] Currently, most coking coal screening mechanisms lack a stirring and turning structure for the raw materials. Due to the large quantity of coking coal during screening, the raw materials accumulated in the middle are difficult to screen, thus reducing the uniformity of coking coal screening and the screening effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 A coking coal screening mechanism includes: a screening base 1, a fixed frame 9 connected to one side of the screening base 1, a hydraulic rod 10 provided on one side of the fixed frame 9, an outer frame 8 connected to one end of the hydraulic rod 10, a screening frame 4 connected to the inner wall of the outer frame 8, a feeding frame 5 provided on the top of the screening frame 4, a screen hole 16 opened at the bottom of the screening frame 4, a support plate 13 connected to the back of the screening frame 4, and a first motor 14 connected to the top of the support plate 13.

[0026] The output shaft of the first motor 14 is connected to a lead screw 7. A movable block 15 is movably connected to the outer wall of the lead screw 7. A movable bracket 6 is connected to the back of the movable block 15. A support frame 18 is connected to one end of the movable bracket 6. A motor protection box 19 is fixedly connected to one side of the support frame 18. A second motor 21 is installed on the inner wall of the motor protection box 19. The output shaft of the second motor 21 is connected to a rotating shaft 20. A tipping hopper 17 is connected to one end of the rotating shaft 20. During the screening of coking coal granular raw materials, the hopper can agitate and tip the raw materials at different positions so that the raw materials can continuously change positions during the screening process. This avoids the problem of the middle part not being effectively screened due to excessive raw material volume, thereby further improving the uniformity of raw material screening and also further improving the screening effect.

[0027] The top of the screening frame 4 is provided with a movable hole. One end of the movable support 6 passes through the movable hole, penetrates the top of the screening frame 4, and extends into the interior of the screening frame 4. This allows the movable support 6 to move up and down inside the screening frame 4 when the first motor 14 drives the lead screw 7 to work. This allows the height of the tipping hopper 17 to be adjusted so that the tipping hopper 17 can stir and tip the raw materials at different depths inside the screening frame 4.

[0028] Among them, one side of the screening base 1 is connected to a telescopic sleeve rod 3 through a fixed frame 9, and the inner wall of the telescopic sleeve rod 3 is telescopically connected to a movable rod 2. One end of the movable rod 2 is fixedly connected to the outer wall of the outer frame 8. When the screening frame 4 moves horizontally left and right, it can drive the movable rod 2 to move telescopically within the telescopic sleeve rod 3, thereby supporting and limiting the horizontal movement of the screening frame 4, and further improving the stability of the movement of the screening frame 4 during the screening process.

[0029] The screening base 1 has a material discharge hole 11 at the top and a material discharge frame 22 on the inner bottom wall of the screening base 1. The material discharge frame 22 is located directly below the material discharge hole 11 and can collect the screened material during the screening process.

[0030] The inner wall of the feed frame 5 is movably connected with a sealing plug, and the sealing plug is engaged with the feed frame 5. This can seal the feed frame 5 after feeding, preventing dust from being dispersed through the feed frame 5 during the screening process and causing adverse effects on the surrounding staff.

[0031] The shape and size of the tipping hopper 17 are matched with the shape and size of the screening frame 4, and the tipping hopper 17 is located inside the screening frame 4. The matching tipping hopper 17 and the feeding frame 5 facilitate the tipping hopper 17 to rotate inside the screening frame 4.

[0032] The screening frame 4 is provided with a hinge on its surface, and a sealing door 12 is movably connected to the surface of the screening frame 4 via the hinge. The sealing door 12 is provided with a lock hole on its surface, which allows the screening frame 4 to be opened through the sealing door 12 so that the raw materials can be collected after screening.

[0033] The inner wall of the discharge hole 11 is provided with a sliding groove, and the bottom of the screening frame 4 is connected to a sliding frame. The inner wall of the sliding groove can slide with the outer wall of the sliding frame. Therefore, during the movement of the screening frame 4, the sliding frame can slide in the sliding groove, which further improves the stability of the movement of the screening frame 4.

[0034] Working principle: When screening coking coal raw material particles is required, the raw material is placed into the screening frame 4 through the feed frame 5. Then, the feed frame 5 is closed by the sealing plug. The hydraulic rod 10 is activated to drive the outer frame 8, causing the screening frame 4 to move horizontally at high speed. During the left and right movement of the screening frame 4, the raw material can be screened. Smaller particles in the raw material fall into the discharge frame 22 through the screen holes 16 after screening and are collected. During the screening process, the second motor 21 can be activated to drive the rotating shaft 20 to rotate the tipping hopper 17. During the rotation of the tipping hopper 17, the raw material can be agitated and tipped. During the tipping process, the first motor 14 can be activated to drive the lead screw 7 to move the movable block 15. The movable block 15 drives the movable support 7 to move the support frame 18 up and down horizontally. The support frame 18 can adjust the height of the tipping hopper 17, which facilitates the stirring and tipping of raw materials at different depths in the screening frame 4, further improving the uniformity of raw material screening.

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