Description

Technical Field

[0001] The utility model relates to the technical field of CDQ furnace cold coke charging, in particular to a CDQ furnace cold coke charging device. Background Art

[0002] The traditional method of loading cold coke is to open the manhole at the cooling section of the dry quenching furnace and make a coke loading chute at the manhole. The coke frame filled with cold coke is lifted by a crane and then the coke is loaded into the coke loading chute. After a certain amount of coke is loaded, personnel enter the dry quenching furnace to manually flatten the coke into shape, and the cycle is repeated until it is full. However, each time of loading coke takes a very long time, and the time for manually flattening the coke is relatively long. It usually takes 1-2 days to complete a coke loading, and the investment in manpower, resources and equipment is relatively large.

[0003] A dry quenching cold coke loading device is disclosed in a Chinese patent (CN216662963U), including a loading device, the loading device including a bottom plate, and a support frame is fixed on the upper surface of the bottom plate. In the utility model, a loading device, a receiving hopper, a lower hopper, a support plate, a second motor, a gear and a convex tooth are provided, and the loading device includes a bottom plate, a support frame, a U-shaped groove, a moving wheel, a driven roller, an active roller and a first motor, so that the cold coke can be lifted from the bottom end of the loading device to the inside of the receiving hopper, so that the cold coke falls from the receiving hopper to the inside of the lower hopper, and the bottom of the lower hopper is designed with an inclined mouth, and at the same time, the second motor will drive the gear to rotate, and the gear will mesh with the convex teeth on the outer wall of the lower hopper, so that the lower hopper will be driven to rotate at a uniform speed at the bottom of the receiving hopper, so that the cold coke can fall into the dry quenching furnace in a dispersed manner, preventing the cold coke from accumulating in the middle position, thereby shortening the time for manual leveling of the cold coke and improving the loading efficiency.

[0004] The above patent delivers cold coke into the dry quenching furnace by rotating the lower hopper with an inclined mouth. However, this method of adding cold coke causes the cold coke to enter the positions around the inside of the dry quenching furnace, but the middle position may not be filled, resulting in a pit in the middle position of the dry quenching furnace, and the cold coke cannot be completely spread out. It is necessary to manually enter the dry quenching furnace to manually flatten the coke into a shape. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] The present invention will be further described below in conjunction with the embodiments.

[0024] like Figure 1 - Figure 4 As shown, the utility model proposes a dry quenching furnace cold coke loading device, comprising a support frame 1 installed at the dry quenching furnace mouth when in use, a coke feeding mechanism for evenly loading cold coke into the dry quenching furnace, and a coke transport mechanism for providing cold coke to the feeding mechanism.

[0025] The coke feeding mechanism includes a mounting base 201 which is fixed on the support frame 1 and is located directly above the furnace mouth. The mounting base 201 is a cylindrical structure in which two sections of cylinders with different diameters are connected by a conical surface in the middle. A lower coke bin 202 is rotatably installed in the mounting base 201. The lower coke bin 202 has a similar structure to the mounting base 201. A partition plate 203 is fixed in the middle of the lower coke bin 202 for dividing the lower coke bin 202 into two halves, so that the lower coke bin 202 is divided into two chambers, a first chamber 204 for feeding cold coke to the surrounding areas of the furnace and a second chamber 205 for feeding cold coke to the center of the furnace.

[0026] The lower end of the first chamber 204 is connected with a coke guide tube 206 which is in the same vertical plane as the first chamber 204 and has an angle greater than 90° with the first chamber 204 , and is used to guide the cold coke items entering the first chamber 204 around the furnace.

[0027] The coke ejection mechanism also includes a driving assembly for rotating the lower coke bin 202 relative to the mounting seat 201, and the driving assembly includes a gear ring 207 fixed on the upper part of the lower coke bin 202. A notch 212 is provided at the same height as the mounting seat 201 and the gear ring 207, so that a portion of the gear ring 207 can be exposed. A first motor 208 is fixedly installed on one side of the notch 212 on the support frame 1, and a driving gear 209 is installed on the output shaft of the first motor 208. The driving gear 209 is meshed with the gear ring 207, and the lower coke bin 202 is driven to rotate by the motor.

[0028] Bearings 210 are installed at both ends between the lower coke bin 202 and the mounting seat 201. A circle of several balls 211 are rolled on the inner wall of the middle inclined surface of the mounting seat 201 to reduce the friction between the rotating lower coke bin 202 and the inner wall of the mounting seat 201.

[0029] The coke transport mechanism includes two groups of coke delivery assemblies located on both sides of the lower coke bin 202 for delivering cold coke from a lower position to the lower coke bin 202. Each coke delivery assembly includes a coke delivery part for delivering cold coke from a lower position to a higher position and an upper coke part for providing cold coke to the coke delivery part. The coke delivery part includes two mounting plates 301 arranged opposite and obliquely. The upper end of the mounting plate 301 is fixed to the support frame 1 by bolts. A driven roller 302 is rotatably mounted on the upper end of the mounting plate 301, and an active roller 30 is rotatably mounted on the lower end. 4. A plurality of supporting rollers 303 are installed in the middle section for rotation. A conveyor belt 305 is sleeved on the outer side of the active roller 304, the driven roller 302 and the supporting roller 303. The active roller 304 drives the conveyor belt 305 to work. The supporting roller 303 supports the conveyor belt 305 in the middle section. The mounting plate 301 is located above the conveyor belt 305 and is at least 20 cm higher than the conveyor belt 305. The driven roller 302 is located above the lower coke bin 202 and is directly above the range of the lower coke bin 202.

[0030] The upper coke portion includes an upper coke box 306 arranged at the lower end of the mounting plate 301. The side wall opening of the upper coke box 306 extends through the notch of the mounting plate 301 into the upper coke box 306 and is fixed to the upper coke box 306 by bolts. The upper coke box 306 has an upper coke opening 308 at the top. A hopper 307 is fixed above the upper coke box 306. The lower end of the hopper 307 contacts the mounting plate 301 and is stuck on the mounting plate 301, forming a structure as shown in the attached figure. Figure 1 and Figure 2 In the semi-enclosed structure shown, the staff uses a horizontal conveyor or manual means to deliver the cold coke from the upper coke port 308 into the hopper 307, and the cold coke falls onto the conveyor belt 305 through the outlet of the hopper 307. Since the hopper 307 is connected to the mounting plate 301, only one side of the conveyor belt 305 is open, and the cold coke will not fall from the conveyor belt 305.

[0031] A second motor 309 is fixed in the upper coke box 306 . The second motor 309 is connected to the active roller 304 through a reducer and a coupling to drive the active roller 304 to rotate, thereby driving the conveyor belt 305 to work.

[0032] When the utility model is working, the staff first installs the support frame 1 at the furnace mouth of the dry quenching furnace top, then installs the mounting plate 301 of the coke transport mechanism and the upper coke box 306, starts the first motor 208 and the second motor 309, and then sends the cold coke from the upper coke mouth 308 into the hopper 307 through a horizontal conveyor or manually, and falls on the conveyor belt 305. The second motor 309 drives the active roller 304 to rotate, thereby driving the conveyor belt 305 to work, and the cold coke is transported from a low place to a high place and sent to the lower coke bin 202. The lower coke bin 202 rotates driven by the first motor 208. Since there are two sets of coke delivery assemblies on both sides of the lower coke bin 202, when the lower coke bin 202 rotates, the first bin 204 and the second bin 205 can both receive cold coke, and then deliver it to the dry quenching furnace. The cold coke in the first bin 204 is guided to the surroundings of the dry quenching furnace by the coke guide tube 206, and the cold coke in the second bin 205 is guided to the center of the dry quenching furnace, so that the cold coke in the dry quenching furnace is evenly distributed, and there is no need for personnel to enter the dry quenching furnace to level the coke.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
