TECHNICAL FIELD
[0001] The utility model relates to coke screening and transfer technical field, concretely relates to a coking coke high -efficient screening and transfer system. BACKGROUND
[0002] In prior art, coking coke quenching and transfer usually includes the following processes: the quenching car carries red coke into the quenching tower, after being extinguished by water spraying, the quenching car drives to the coke drying table, opens the side door of the quenching car, and pours the extinguished coke onto the coke drying table, the coke is dried and the water vapor is removed, and then is put into the belt conveyor of the coke drying table, and then is transported by several transfer belts to the coke screening tower for screening, and the screened products are transported to the coke storage yard or coke bin for storage by the belt conveyor.
[0003] At present, the existing coke screening and transfer system still has the following problems: first, the coke transported by quenching and transfer usually needs to be turned over for several times and transported by several transfer stations and several conveyors, because the coke has a large volume, the chute is often blocked, which causes the jamming of the conveyor belt and even damages the belt, and affects the normal transportation of the coke; second, during the transportation of the coke, because there is a certain height difference between the transfer stations, the coke falls from high to low, and a large amount of collision and friction occurs between the coke and the coke, between the coke and the chute wall, and between the coke and the ground, which causes the damage of the coke, and further reduces the volume of the coke, and even generates a large amount of coke powder, and in addition, during the vibration screening of the coke, a large amount of coke is also broken, which further affects the quality and value of the coke. Therefore, it is an urgent need to develop a coking coke high -efficient screening and transfer system which is not easy to block and jam, has smooth transportation, and has low coke breaking rate.

[0008] Further, the outer side of the belt conveyor and the screening mechanism is provided with a sealing shell, the top of the sealing shell is provided with a dust exhaust pipe.
[0009] Further, the side of the feeding end of the belt conveyor is provided with a slag cleaning mechanism, the slag cleaning mechanism comprises a rotating shaft and a slag cleaning rod arranged on the rotating shaft, the short rods are arranged in rows, the end of the slag cleaning rod extends into the inside of the short rod and is staggered with the short rod.
[0010] Further, the sealing shell below the belt conveyor is obliquely arranged, the lower end of the sealing shell is below the slag cleaning mechanism, and the lower end of the sealing shell is provided with a slag discharge port.
[0011] Further, the end of the short rod is provided with a pad, and the pad is provided with a buffer cushion.
[0012] Further, the upper coke fines screen, the coke particle screen and the lower coke fines screen all comprise a plurality of circular rods arranged at intervals, one end of the circular rod is drivingly connected with a driving mechanism capable of driving the circular rod to rotate.
[0013] In operation, after the coke has cooled, the scraper is opened to allow the coke on the cooling platform to enter the feed end of the belt conveyor. Several rows of dividing bars are installed on the belt conveyor surface, forming a relatively independent coke storage area between every two rows. The coke is placed in each of these storage areas. Simultaneously, short rods are also installed on the belt conveyor surface to support the coke. Larger coke lumps are positioned above the short rods, while smaller coke dust and particles fall into the gaps between the short rods. During the vibration of the belt conveyor, the coke dust and particles continuously fall, completing the transfer and initial transport of the coke when it reaches the discharge end of the belt conveyor. In the first screening step, under the influence of gravity, large coke lumps slide down the separator bar onto the upper slide plate, and then continue to slide, passing through the upper coke flake screen and the coke particle screen in sequence. The coke flakes and coke particles mixed in with the coke lumps are screened out one by one. The coke flakes fall into the upper coke flake box, the coke particles fall into the upper coke particle box, and the larger coke lumps fall into the coke lump box. At the same time, the coke flakes and coke particles falling onto the belt conveyor surface fall onto the lower slide plate through the discharge end of the belt conveyor. During the sliding process along the lower slide plate, the coke flakes are screened out by the lower coke flake screen and fall into the lower coke flake box, while the slightly larger coke particles fall into the lower coke particle box. This process efficiently completes the screening and transfer of coking coke. In this invention, multiple rows of dividing bars are installed on the belt conveyor. During coke conveying and transfer, the long dividing bars, located within the coke storage areas separated by these bars, propel the coke forward, preventing chute blockage caused by large coke volumes and solving the belt conveyor jamming problem. Simultaneously, the shorter bars separate the coke from the belt, preventing belt damage and ensuring normal coke transport. Secondly, large pieces of coke slide from the conveyor outlet onto the upper sliding plate via the dividing bars, eliminating the drop height issue and preventing coke breakage. Small coke particles and coke dust fall onto the lower sliding plate for screening. This sliding screening structure reduces collisions and friction between coke particles compared to vibrating screening, preventing the generation of coke particles and dust, and ensuring the quality and value of the coke. In summary, this invention has the advantages of being less prone to blockage, smooth transport, low coke breakage rate, and high working efficiency. Attached Figure Description

DETAILED DESCRIPTION
[0017] The utility model will be further explained in connection with the drawings, but in any way to the utility model is limited, based on the utility model is made, any change or improvement, all belong to the protection scope of the utility model.
[0018] As Figs. 1-2 shown, the utility model includes belt conveyor 1 and screening mechanism, belt conveyor 1 is prior art, is used for the conveying and transfer of coke, and the belt surface of belt conveyor 1 is provided with multiple rows of partition rods along its length direction, each row of partition rods includes several uniformly arranged long rods 2, several short rods 3 are arranged at the belt surface of belt conveyor 1 between the adjacent two rows of partition rods, and the length of short rod 3 is shorter than the length of long rod 2, the screening mechanism includes upper slide plate 4 and lower slide plate 5 that are arranged obliquely and are arranged in upper and lower structure, the higher end of upper slide plate 4 is located at the side of the discharge end of belt conveyor 1, and the higher end of lower slide plate 5 is located below the discharge end of belt conveyor 1, upper coke fines screen 6 and coke particle screen 7 are sequentially arranged from high to low on upper slide plate 4, upper coke fines box 8 is arranged below upper coke fines screen 6, upper coke particle box 9 is arranged below coke particle screen 7, coke block box 10 is arranged below the lower end of upper slide plate 4, lower coke fines screen 11 is arranged on lower slide plate 5, lower coke fines box 12 is arranged below lower coke fines screen 11, and lower coke particle box 13 is arranged below the lower end of lower slide plate 5.
[0019] The utility model discloses a coke conveying and transporting device, which comprises a coke drying platform, a coke conveying and transporting device and a coke conveying and transporting device.
[0020] In the utility model, a plurality of rows of separation rods are arranged on the belt conveyor 1, and the coke is located in each coke storage area separated by the separation rods during the conveying and transporting process of the coke. The length of the separation rods is relatively long, which can push the coke in the coke storage area forward to avoid the phenomenon of clogging the chute caused by the large volume of the coke and solve the problem of jamming of the belt conveyor. Meanwhile, the coke is separated from the belt by the short rods 3, which can also prevent the damage of the belt and ensure the normal transportation of the coke. Secondly, the large coke blocks slide from the discharge end of the belt conveyor 1 to the upper slide plate 4 through the separation rods, which eliminates the problem of the falling gap of the coke and prevents the breakage of the coke. The small coke particles and coke fines fall onto the lower slide plate 5 for screening. The structure of the sliding screening is used for the screening of the coke, which reduces the collision and friction between the coke, avoids the generation of the coke particles and coke fines, and ensures the quality and value of the coke.
[0021] Preferably, the upper slide plate 4 and the lower slide plate 5 are made of marble. In actual use, other materials with hard texture and smooth surface can also be used.
[0022] The higher end of the upper slide plate 4 is uniformly provided with a plurality of poking rods 14 which extend into the inside of the long rod 2 and are staggered with the long rod 2. During the coke conveying process, when reaching the discharge end of the belt conveyor 1, large coke pieces slide along the long rod 2 to the upper slide plate 4, but in the actual operation process, it is found that part of the coke pieces cannot slide from the long rod 2 to the upper slide plate 4 in time and continue to fall to the lower slide plate 5, affecting the normal operation of the system. In order to solve the above problems, the poking rod 14 is arranged, which can lift the large coke pieces and replace the role of the long rod 2, so that the coke pieces slide along the long rod 2 to the upper slide plate 4, ensuring that all large coke pieces can smoothly slide to the upper slide plate 4 and ensuring the screening effect of the coke.
[0023] The outer side of the belt conveyor 1 and the screening mechanism is provided with a sealing shell 15, and the top of the sealing shell 15 is provided with a dust exhaust pipe. The utility model inevitably produces a large amount of dust during operation, and the diffusion of these dusts will pollute the surrounding environment and harm the health of the surrounding workers. In order to avoid this problem, the sealing shell 15 is arranged to seal the pollution source capable of producing dust in the sealing shell 15, and the dust is uniformly discharged and treated through the dust exhaust pipe.
[0024] One side of the feeding end of the belt conveyor 1 is provided with a slag cleaning mechanism, and the slag cleaning mechanism comprises a rotating shaft 16 and a slag cleaning rod 17 arranged on the rotating shaft 16. The short rod 3 is arranged in rows and columns in an orderly manner, and the end of the slag cleaning rod 17 extends into the inside of the short rod 3 and is staggered with the short rod 3. In the long-term use process of the utility model, due to the irregular shape of coke and other reasons, part of the coke slag will be stuck in the gap between the short rods 3. In the long run, it affects the normal operation of the system. In order to remove these slag, the existing equipment is used to drive the rotating shaft 16 to rotate during operation, and the rotating shaft 16 drives the slag cleaning rod 17 to rotate. The slag cleaning rod 17 cleans the coke slag stuck between the short rods 3 during rotation, ensuring the long-term normal operation of the utility model.
[0025] The sealing shell 15 below the belt conveyor 1 is inclinedly arranged, the lower end of the sealing shell 15 is located below the slag cleaning mechanism, and the lower end of the sealing shell 15 is provided with a slag discharge port 18. The utility model uses the slag cleaning mechanism to clean the slag stuck between the short rods 3. The slag falls to the bottom of the sealing shell 15 and then slides to the lowest end along the sealing shell 15 and is discharged from the slag discharge port 18.
[0026] The end of the short rod 3 is provided with a pad 19, and the pad 19 is provided with a buffer cushion. Since the diameter of the short rod 3 is small, the contact area with the coke is small, which leads to a large local pressure of the coke, and thus the coke is easy to be broken, increasing the breaking rate of the coke. Therefore, the pad 19 and the buffer cushion are arranged at the end of the short rod 3, which can increase the contact area with the coke and also buffer the impact force, thereby preventing the coke from being broken.
[0027] The upper coke fines screen 6, the coke particle screen 7 and the lower coke fines screen 11 each comprise a plurality of circular rods 20 arranged at intervals, one end of the circular rod 20 is drivingly connected with a driving mechanism capable of driving the circular rod 20 to rotate, the driving mechanism is a prior structure, in actual use, a gear can be arranged at one end of the circular rod 20, a plurality of gears are connected by a chain, and one end of one of the circular rods 20 is connected with a motor and a transmission, all the circular rods 20 can be driven to rotate by the motor and the transmission, in this way, when the coke passes through the area of the upper coke fines screen 6, the coke particle screen 7 and the lower coke fines screen 11, since all the circular rods 20 are in a rotating state, the large particle coke can be pushed to slide forward, and the problem of mesh blockage existing at present can be solved.
