Description

Technical Field

[0001] This utility model relates to the field of coke oven technology, and specifically to a coke charging device. Background Technology

[0002] Coking is the process of producing coke, coke oven gas, and chemical products by dry distilling blended coking coal in the absence of air. The main equipment for coking is the coke oven, which uses blast furnace gas or coke oven gas combustion to provide heat for coal dry distillation.

[0003] In the existing technology, when loading coke into a coke oven, the material car is lifted and then the material is loaded into the dry oven. When the crane is lifting the material car, in order to avoid the material car shaking due to inertia, the crane's traveling speed can only be controlled within a certain range, and the speed is gradually increased or decreased at the beginning and end of the travel phase. This affects the lifting efficiency of the material car and the coke loading efficiency. Utility Model Content

They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] like Figures 1-3 As shown, this utility model discloses a coke loading device, including a feeding mechanism 100, a crane 200, a material box 300, and a material transport trolley 400. The feeding mechanism 100 is located on the top of the dry-fire furnace 500. The material transport trolley 400 carries the material box 300 containing materials. The crane 200 lifts the material box 300 to the top of the dry-fire furnace 500 for coke loading.

[0034] The material box 300 is truncated cone-shaped with the smaller diameter end facing down. The bottom edge of the material box 300 is provided with a gasket ring 303, the top edge of the material box 300 is provided with a protruding flange 301, and the bottom edge of the flange 301 is provided with a retaining ring 302.

[0035] The bottom center of the material bin 300 has a circular material inlet 305. The bottom surface of the material bin 300 outside the material inlet 305 is a frustum shape with the smaller diameter end facing down, so that the material inside the material bin 300 can slide onto the bottom surface of the material bin 300 towards the material inlet 305. Above the material inlet 305 is a conical block 304 with the cone section facing up. The diameter of the bottom surface of the block 304 is larger than the inner diameter of the material inlet 305. The bottom of the block 304 is coaxially connected to a sliding rod 307, and the bottom end of the sliding rod 307 is coaxially connected to a disc-shaped movable plate 308.

[0036] A sliding sleeve 306 is provided inside the feed opening 305, which is coaxial with it. The top surface of the sliding sleeve 306 is flush with the top surface of the feed opening 305. The inner diameter of the sliding sleeve 306 is adapted to the sliding rod 307. The sliding sleeve 306 is slidably sleeved on the outer wall of the sliding rod 307. Multiple support rods connected to the inner wall of the feed opening 305 are connected on the outer wall of the sliding sleeve 306. The support rods are arranged at an inclination inside the feed opening 305 and the higher end is connected to the outer wall of the sliding sleeve 306. The projection of the support rods on the horizontal plane is arranged radially along the feed opening 305. Multiple support rods are arranged at equal intervals in the circumferential direction of the sliding sleeve 306.

[0037] Under gravity, the block 304 slides down to the bottom of the hopper 300. The bottom of the block 304 contacts the bottom of the hopper 300 outside the feed port 305. At this time, the bottom surface of the movable plate 308 is not lower than the bottom surface of the pad ring 303, that is, the movable plate 308 does not extend outside the pad ring 303. When filling the hopper with material, the block 304 blocks the feed port 305. If the block 304 slides up and exposes the feed port 305, the material in the hopper 300 can be output from the feed port 305.

[0038] The material handling trolley 400 includes a base 401, on which pulleys 402 are rotatably mounted. The top of the base 401 is provided with a groove 403 whose shape is adapted to the material box 300. The lower inner wall of the groove 403 is cylindrical in shape, which is adapted to the shape of the gasket 303, and the upper inner wall of the groove 403 is frustum-shaped, which is adapted to the shape of the outer wall of the material box 300. The height of the top of the groove 403 is about half the height of the material box 300.

[0039] The crane 200 includes two crossbeams erected at a certain height. The bottom of the crossbeams is provided with a support column (not shown in the figure). The two crossbeams are arranged in parallel and at the same height. A longitudinal beam perpendicular to the crossbeams slides between the two crossbeams. A traveling trolley 201 slides on the longitudinal beam. The lower part of the traveling trolley 201 is provided with a clamping mechanism for clamping the material box 300. A winch is provided on the traveling trolley 201. The wire rope of the winch is connected to the clamping mechanism.

[0040] The clamping mechanism includes a cylindrical base 204, with multiple grippers 205 hinged to the top edge of the base 204. The grippers 205 are evenly spaced along the circumference of the base 204, and a steel wire rope is connected to the top of the base 204. The grippers 205 are L-shaped, including a horizontal section and a vertical section connected to each other. A slot is provided at the top edge of the base 204, and the end of the horizontal section is hinged in the slot. A torsion spring connected to the end of the horizontal section is provided in the slot. Driven by the elastic force of the torsion spring, the horizontal section swings downward until it contacts the bottom surface of the slot. At this time, the horizontal section is horizontal and located radially upward on the base 204, the vertical section is vertical, and the grippers 205 can swing upward, that is, the horizontal section can swing upward. At this time, the torsion spring is compressed.

[0041] A guide block 209 is connected to the inner side of the bottom end of the vertical section. The side wall of the guide block 209 away from the vertical section is inclined, and the inclined surface of the guide block 209 moves towards the vertical section in the downward vertical direction, making the cross-section of the guide block 209 triangular. A retaining block 210 that mates with the retaining ring 302 is provided on the top side of the guide block 209 away from the vertical section. The retaining block 210 is vertically convex, and an elastic pad is provided on the top of the retaining block 210. The distance between the retaining block 210 and the vertical section is not less than the thickness of the retaining ring 302.

[0042] The base 204 is positioned above the material box 300 and descends. The inclined surface of the guide block 209 slides into contact with the edge of the flange 301 at the top of the material box 300. At this time, the guide block 209 swings outward, and the gripper 205 swings outward accordingly. The torsion spring is compressed. After the guide block 209 and the locking block 210 slide past the flange 301, under the elastic force of the torsion spring, the gripper 205 swings down so that its vertical part contacts the flange 301 and the outer wall of the retaining ring 302. At this time, the locking block 210 is located inside the retaining ring 302. After the base 204 rises, the locking block 210 can abut against the bottom of the flange 301 inside the retaining ring 302, thereby realizing the clamping mechanism and the material box 300.

[0043] The top of the horizontal section of the gripper 205 is equipped with a vertical column 206. A rotating column 207 is rotatably mounted at the top center of the base 204. A rotating column is coaxially connected to the top of the rotating column 207. A pull rope 208 connects the rotating column 207 and the column 206. When the gripper 205 is reset, that is, when the horizontal section of the gripper 205 rests against the bottom surface of the slot, the pull rope 208 is taut. Rotating the rotating column 207 pulls the pull rope 208, causing the column 206 to move closer to the rotating column 207, and the gripper 205 swings upward. When the gripping mechanism is removed from the material box 300, the base 204 descends, causing the locking block 210 to slide down below the locking ring 302. Then, rotating the rotating column 207 pulls the pull rope 208, causing the column 206 to swing towards the rotating column 207, and the gripper 205 swings outward accordingly. Finally, the base 204 moves upward, allowing the gripper 205 to disengage from the material box 300.

[0044] Below the traveling trolley 201 is a fixing ring 202 corresponding to the base 204. The fixing ring 202 is circular. Multiple pull rods connect the top of the fixing ring 202 to the traveling trolley 201, fixing the fixing ring 202 in place. At the bottom of the fixing ring 202 are multiple slots 203 corresponding to the columns 206. The inner diameter of the slots 203 corresponds to the outer diameter of the columns 206, and the bottom inlet of the slots 203 has a flared, frustum-shaped structure. When the hoisting equipment operates and moves the base 204 upward, multiple columns 206 can be inserted into the slots 203. At this time, the base 204 is fixed by the fixing ring 202, and the base 204 will not wobble when sliding with the traveling trolley 201.

[0045] The feeding mechanism 100 includes a support plate 101 horizontally disposed on the top of the dry sintering furnace 500. The support plate 101 is provided with a discharge hole that matches the feeding hole on the top of the dry sintering furnace 500. A slide block 102 is slidably disposed on the support plate 101. A cylinder is provided on the support plate 101 to drive the slide block 102 to slide. The slide block 102 is equipped with a material cover 103 and a feed cylinder 104. The upper inner wall of the feed cylinder 104 is shaped like a frustum to fit the outer wall of the material box 300. The middle inner wall of the feed cylinder 104 is cylindrical with an inner diameter that fits the washer ring 303. A support ring 105 that mates with the washer ring 303 is provided on the middle inner wall of the feed cylinder 104. A support rod 107 coaxially arranged with the support ring 105 is provided on the inner side of the support ring 105. Multiple connecting rods 106 connected to the inner wall of the support ring 105 are provided on the outer wall of the support rod 107. A fixed plate 108 that mates with the movable plate 308 is coaxially connected to the top of the support rod 107. The lower part of the feed cylinder 104 is shaped like a frustum with the smaller diameter end facing upwards. The inner diameter of the bottom end of the feed cylinder 104 matches the inner diameter of the material discharge hole of the support plate 101.

[0046] During coke loading, the material transport trolley 400 carries the material bin 300, which is placed in the bin trough 403, ensuring its secure mounting on the trolley 400. Once the trolley 400 reaches its designated position, the crane 200 operates, positioning the clamping mechanism above the material bin 300. The winch then drives the clamping mechanism downwards, lowering the base 204 until the guide block 209 slides past the top edge of the material bin 300. The locking block 210 at the bottom of the gripper 205 then springs back to the inside of the retaining ring 302. The winch then drives the base 204 vertically upwards, clamping the material bin 300 and lifting it vertically until the base 204 reaches the multiple columns. 206 is inserted into multiple slots 203 at the bottom of the fixing ring 202. At this time, the base 204 is fixed and the material box 300 is also fixed. Then, the traveling trolley 201 moves, driving the base 204 and the material box 300 to move quickly. During the movement, since the base 204 and the material box 300 are inserted into the slots 203 of the fixing ring 202 through the column 206, the base 204 and the material box 300 are temporarily rigidly connected to the traveling trolley 201. The base 204 and the material box 300 will not shake due to the rapid acceleration, deceleration and change of direction of the traveling trolley 201, so that the material box 300 can quickly reach the top of the feeding mechanism 100. Before the material box 300 reaches above the feeding mechanism 100, the slide block 102 slides so that the feeding cylinder 104 is on the material discharge hole of the support plate 101. After the material box 300 reaches directly above the feeding cylinder 104, the hoisting device drives the base 204 to descend. The base 204 drives the material box 300 to descend vertically. The material box 300 enters the upper part of the feeding cylinder 104 until the bottom pad ring 303 of the material box 300 contacts the support ring 105. During the descent of the material box 300, the fixed plate 108 contacts the movable plate 308 and lifts it. The rise of the movable plate 308 causes the block 304 to rise, and the bottom material port 305 of the material box 300 is opened. The material in the material box 300 is output from the material box 300 through the material port 305 and enters the dry furnace 500 through the feeding cylinder 104. After coke loading is completed, the hoisting device drives the base 204 to rise, and the material box 300 rises away from the feed cylinder 104. The block 304 at the bottom of the material box 300 slides down under gravity to block the material inlet 305. After the material box 300 slides away from the feed cylinder 104, the slide block 102 slides to make the material cover 103 slide onto the discharge hole of the support plate 101 to block it. After the material box 300 is placed on the material transport trolley 400, the base 204 slides down to make the clamping block 210 slide out of the inner side of the clamping ring 302. Then the rotating column 207 is rotated, and multiple grippers 205 swing upward to make the clamping block 210 disengage from the inner side of the clamping ring 302. Then the base 204 rises to make the clamping mechanism disengage from the material box 300.

[0047] The material box 300 of this utility model is stably fixed on the material transport trolley 400, which can move quickly to improve the transfer efficiency of the material box 300. The clamping mechanism of the crane 200 can automatically engage with the material box 300 by sliding down, improving work efficiency. After the clamping mechanism engages with the material box 300, the winch drives it to rise, so that the column 206 on the clamping mechanism can be inserted into the slot 203 fixed on the fixing ring 202 at the bottom of the traveling trolley 201, thus allowing the material box 300 to be moved. With a temporary rigid connection to the traveling trolley 201, the traveling trolley 201 can quickly move the material box 300 to the top of the dry refrigeration furnace 500 without worrying about the material box 300 shaking. The material box 300 at the top of the dry refrigeration furnace 500 can be directly lowered into the feeding cylinder 104, which can realize the automatic opening of the bottom material port 305 of the material box 300 for material discharge. The operation efficiency is high. When the clamping mechanism is separated from the material box 300, rotating the rotating column 207 can realize that multiple grippers 205 can be simultaneously lifted and detached from the material box 300.

[0048] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
