Description

Technical Field

[0001] The utility model relates to the technical field of carbonization chambers, in particular to a graphite cleaning device for the top of a carbonization chamber. Background Technique

[0002] A carbonization chamber refers to a device for producing coke. Usually, coal is heated at a high temperature to produce coke. In the carbonization chamber, the coal undergoes pyrolysis at a high temperature, causing its volatile components to be released, leaving behind coke. However, during the coke production process, the top of the carbonization chamber is often adhered with graphite. When loading coal, the top of the coal cake rubs against the graphite on the top of the carbonization chamber, resulting in the generation of floating pulverized coal, which in turn affects the quality of the coke. Therefore, it is necessary to regularly clean the graphite on the top of the carbonization chamber to ensure production efficiency and safety.

[0003] When cleaning the graphite on the top of the carbonization chamber, the traditional method is to install a set of scrapers at the top end of the coke pusher head. During the process of pushing coke by the coke pusher head, the scrapers synchronously scrape off the graphite adhered to the top of the carbonization chamber.

[0004] However, the single scraper scraping method will increase the wear rate of the scraper and increase the frequency of replacing the scraper. In addition, the scraped graphite is not effectively collected, which will cause the scraped graphite to fall into the coke, thereby affecting the overall quality of the coke. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a graphite cleaning device for the top of a carbonization chamber. The technical solution of the utility model is as follows:

[0006] A graphite cleaning device for the top of a carbonization chamber includes a collection box, the collection box is movably connected inside a placement groove opened on the upper surface of the coke pusher head, a collection frame is fixedly connected to the upper surface of the coke pusher head, and the collection frame is communicated with the collection box. Both sides inside the collection frame are movably connected with side plates. An installation hole is penetrated through the upper end of the side surface of the side plate. A fixed pipe is inserted into the installation hole. One end of the fixed pipe is fixedly connected with a steel pipe. The end of the steel pipe far from the fixed pipe is connected with an air compressor through a hose, and the steel pipe is fixedly connected to the side wall of the coke pusher head. The other end of the fixed pipe is fixedly connected with a connecting pipe. A plurality of nozzles are fixedly connected at equal intervals on one side of the connecting pipe. One side inside both groups of side plates is fixedly connected with a fixed seat. A scraper is movably connected to the fixed seat, and the cutting edge of the scraper is flush with the top end of the side plate. A plurality of sliding seats are fixedly connected to the other side inside both groups of side plates. An active scraper is slidably connected to the side of the sliding seat far from the fixed seat.

[0007] Optionally, a fixing plate is fixedly connected to one side of the collection box. The fixing plate and the collection frame are fixed by bolts. A handle is fixedly connected to one side of the fixing plate.

[0008] Optionally, two sets of guide grooves are provided on both inner sides of the collection box. Two sets of guide blocks are fixedly connected to the outer side of the side plate. The guide blocks are slidably connected inside the guide grooves at corresponding positions, and the guide blocks are fixed to the collection box by bolts.

[0009] Optionally, the fixed seat is inclined.

[0010] Optionally, a plurality of slots are provided on the surface of the fixed seat. A plug block is fixedly connected to the lower surface of the scraper. The plug block is slidably connected inside the slot. A locking bolt is threadedly connected to one side of the fixed seat, and the locking bolt abuts against the side surface of the plug block.

[0011] Optionally, limiting grooves are provided on both sides of the slot. Limiting blocks are fixedly connected to both sides of the plug block, and the limiting blocks are slidably connected inside the limiting grooves at corresponding positions.

[0012] Optionally, a chute is provided inside the sliding seat. A slider is fixedly connected to the side of the movable scraper close to the sliding seat. The slider is slidably connected inside the chute. A spring abuts against the lower surface of the slider. The spring is located inside the chute, and the lower end of the spring abuts against the bottom wall of the chute.

[0013] All of the above optional technical solutions can be arbitrarily combined, and the present invention does not elaborate on the structures after combination one by one.

[0014] By means of the above solution, the beneficial effects of the present invention are as follows:

[0015] 1. The graphite on the top of the carbonization chamber is successively cleaned by contacting with the movable scraper, the compressed air sprayed by the nozzle, and the scraper, making the graphite cleaning more thorough and effective. This multiple cleaning method can not only ensure the complete removal of graphite, but also avoid the problem of increased wear rate of the scraper that may be caused by using a single scraper scraping method, prolong the service life of the scraper, and reduce the frequency of replacing the scraper.

[0016] 2. Through the setting of the collection box, the scraped graphite will fall into the collection box, and the graphite can be effectively collected.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following will further describe in detail the specific embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0028] Please refer to Figure 1-8, the utility model provides a graphite cleaning device for the top of the carbonization chamber, which includes a collection box 2. The collection box 2 is movably connected inside a placement groove 11 formed on the upper surface of a coke pusher head 1. A collection frame 3 is fixedly connected to the upper surface of the coke pusher head 1, and the collection frame 3 communicates with the collection box 2. Both sides inside the collection frame 3 are movably connected with side plates 4. An installation hole 42 is formed through the upper end of the side surface of the side plate 4. A fixed pipe 5 is inserted into the installation hole 42. One end of the fixed pipe 5 is fixedly connected with a steel pipe 51. The end of the steel pipe 51 far from the fixed pipe 5 is connected to an air compressor through a hose, and the steel pipe 51 is fixedly connected to the side wall of the coke pusher head 1. The other end of the fixed pipe 5 is fixedly connected with a connecting pipe 52. A number of spray nozzles 53 are fixedly connected at equal intervals on one side of the connecting pipe 52. A fixed seat 6 is fixedly connected to one side inside both groups of side plates 4. A scraper 7 is movably connected to the fixed seat 6, and the blade of the scraper 7 is flush with the top end of the side plate 4. A number of sliding seats 8 are fixedly connected to the other side inside both groups of side plates 4. An active scraping plate 9 is slidably connected to the side of the sliding seat 8 far from the fixed seat 6.

[0029] When the utility model cleans the graphite on the top of the carbonization chamber, the coke pusher head 1 will drive the active scraping plate 9, the compressed air sprayed by the spray nozzles 53, and the scraper 7 to contact the graphite on the top of the carbonization chamber in sequence. First, the active scraping plate 9 scrapes off the relatively loose graphite attached to the top of the carbonization chamber. Subsequently, the spray nozzles 53 continuously spray compressed air towards the top of the carbonization chamber to accelerate the falling of the graphite on the top of the carbonization chamber. Finally, the scraper 7 scrapes off the remaining graphite on the top of the carbonization chamber. By adopting a three-stage step-by-step cleaning method, not only the wear rate of the scraper 7 is reduced, but also the graphite cleaning is more thorough. At the same time, the scraped graphite will fall into the collection box 2, realizing the effective collection of the graphite and avoiding the graphite falling into the coke and affecting the quality of the coke.

[0030] Furthermore, a fixing plate 21 is fixedly connected to one side of the collection box 2. The fixing plate 21 is fixed to the collection frame 3 through bolts. A handle 22 is fixedly connected to one side of the fixing plate 21. The setting of the handle 22 facilitates the staff to quickly take out the collection box 2 from the placement groove 11 when cleaning the graphite inside the collection box 2.

[0031] Furthermore, two groups of guide grooves 31 are formed on both sides inside the collection frame 3. Two groups of guiding blocks 41 are fixedly connected to the outer side of the side plate 4. The guiding blocks 41 are slidably connected inside the guide grooves 31 at corresponding positions. The guiding blocks 41 are fixed to the collection frame 3 through bolts. The height of the side plate 4 can be adjusted according to the actual sizes of the top of the coke pusher head 1 and the top of the carbonization chamber to ensure that the top end of the side plate 4 is in a fitting state with the top of the carbonization chamber.

[0032] Furthermore, the fixed seat 6 is inclined; the scraper 7 is movably installed on the fixed seat 6. The inclination of the fixed seat 6 enables the blade of the scraper 7 to be in full contact with the top of the carbonization chamber, making the graphite cleaning more thorough. At the same time, this design also effectively reduces the force on the blade and extends the service life of the scraper 7.

[0033] Furthermore, a plurality of slots 61 are formed on the surface of the fixed seat 6. A plug 71 is fixedly connected to the lower surface of the scraper 7, and the plug 71 is slidably connected inside the slot 61. One side of the fixed seat 6 is threadedly connected with a locking bolt 63, and the locking bolt 63 abuts against the side surface of the plug 71. The traditional scraper 7 adopts an integral structure. When local wear occurs on the scraper 7, the entire scraper 7 needs to be replaced. In the present utility model, the slot 61 provides an installation position for the scraper 7. A plurality of slots 61 can install a plurality of scrapers 7. When the scraper 7 is worn, only the worn scraper 7 needs to be replaced, without the need for overall replacement.

[0034] Furthermore, limiting grooves 62 are formed on both sides of the slot 61. Limiting blocks 72 are fixedly connected to both sides of the plug 71, and the limiting blocks 72 are slidably connected inside the limiting grooves 62 at corresponding positions. When installing the scraper 7, only the limiting block 72 needs to be aligned with the limiting groove 62, making the installation more convenient. At the same time, the limiting groove 62 plays a role in limiting the limiting block 72, making the scraper 7 more stable when scraping graphite.

[0035] Furthermore, a chute 81 is formed inside the sliding seat 8. A slider 91 is fixedly connected to the side of the movable scraper 9 close to the sliding seat 8, and the slider 91 is slidably connected inside the chute 81. The lower surface of the slider 91 abuts against a spring 92. The spring 92 is located inside the chute 81, and the lower end of the spring 92 abuts against the bottom wall of the chute 81. When the graphite is thick, the movable scraper 9 will move downward, driving the slider 91 to slide inside the chute 81. The chute 81 plays a role in limiting and guiding, ensuring that the movable scraper 9 can only slide along the direction of the chute 81. At the same time, the slider 91 will compress the spring 92. In the compressed state, the spring 92 will exert an elastic force in the opposite direction, making the movable scraper 9 always in a fitting state with the top of the carbonization chamber.

[0036] Working principle: During coke pushing, the air compressor and the coke pushing head 1 operate simultaneously. The air compressor will deliver compressed air through the steel pipe 51 and the fixed pipe 5 to the connecting pipe 52, and finally spray it out from the nozzle 53. During the coke pushing process, the coke pushing head 1 will drive the collection box 3 to move synchronously. At this time, the side plate 4, the scraper 7 and the movable scraper 9 are all in contact with the graphite on the top of the carbonization chamber. As the coke pushing head 1 moves, the movable scraper 9 can scrape off the relatively loose graphite attached to the top of the carbonization chamber and let it fall into the collection box 2. Subsequently, the nozzle 53 continuously sprays compressed air onto the top of the carbonization chamber after being cleaned by the movable scraper 9, so as to accelerate the shedding of the graphite on the top of the carbonization chamber and fall into the collection box 2 (during this process, the side plate 4 and the scraper 7 can be in contact with the top of the carbonization chamber. Under the elastic action of the spring 92, the movable scraper 9 will also always be in close contact with the graphite on the top of the carbonization chamber. At this time, a relatively closed space is formed between the side plate 4, the scraper 7 and the movable scraper 9, avoiding the graphite splashing caused by the compressed air spraying). Finally, the scraper 7 will scrape off the remaining graphite on the top of the carbonization chamber to make the cleaning more thorough, thus completing the cleaning process of the graphite on the top of the carbonization chamber.

[0037] The above description is only the preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
