Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of coking devices, specifically a coking auxiliary device. Background Technology
[0002] Coke pushing refers to the process of using a coke pusher to push coke out of the carbonization chamber in a sequence from the coke pusher in a coke oven. The coke pusher head is an important component of coking machinery. During the pushing process, it comes into direct contact with the coke and the carbonization chamber wall, and is therefore subject to friction and wear. This wear is unavoidable. When the coke pusher head wears out, the entire pusher head needs to be replaced, which is costly. Furthermore, a certain gap needs to be maintained between the coke pusher head and the inner wall of the carbonization chamber to avoid excessive frictional resistance. This results in a small amount of coke being exposed between the coke pusher head and the inner wall of the carbonization chamber during the pushing process and remaining inside the carbonization chamber, leading to incomplete coke pushing. Utility Model Content
[0003] The technical problem this invention aims to solve is that existing pusher devices require the entire pusher head to be replaced after wear, which is costly; and a small amount of coke remains inside the carbonization chamber during the pushing process, resulting in incomplete pushing.
[0004] To solve the above problems, the technical solution of this utility model is as follows: a coking auxiliary device, including a coking head, a coking rod connected to the coking head, a sliding shoe installed below the front end of the coking rod, and a transmission rack installed on the bottom surface of the coking rod. Both sides of the rear end of the coking head can be detachably installed with L-shaped auxiliary plates. A buffer groove is formed between the auxiliary plates and the coking head. A scraper is detachably connected to the bottom cylinder of the rear end of the two auxiliary plates.
[0005] Furthermore, a positioning plate is provided below the coke pusher rod, and support rods are fixedly connected to the top of both ends of the positioning plate. A fixed cylinder is fixedly connected to the top of the support rods, and a limiting rod inserted into the fixed cylinder is fixedly connected to the rear end of the coke pusher head.
[0006] Furthermore, the positioning plate and the end of the fixing cylinder furthest from the coke pusher head are both fixedly installed on the coke pusher car.
[0007] Furthermore, the auxiliary plate has multiple fixing strips fixed to its side that fit against the rear end face of the coke pusher head. The fixing strips have a groove in the middle. The rear end face of the coke pusher head has a threaded rod that passes through the groove. A positioning nut is installed on the threaded rod.
[0008] Furthermore, a positioning rod is fixedly connected to the rear end face of the coke pusher head, and an installation groove that is snapped into the upper part of the scraper is fixedly connected to the end of the positioning rod. The installation groove is a U-shaped structure, and multiple set bolts are threaded through and threaded to its side. The ends of the set bolt rods abut against the scraper.
[0009] The advantages of this invention compared to existing technologies are as follows: the coke pusher head of this invention drives the auxiliary plate and scraper to move, which can effectively reduce the amount of coke left inside the carbonization chamber, push the coke more thoroughly, and only the auxiliary plate and scraper need to be replaced periodically, without replacing the coke pusher head, thus reducing the maintenance cost of the coke pusher.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0015] like Figures 1 to 3 As shown, a coking auxiliary device includes a coking head 1, a coking rod 2 connected to the coking head 1, a sliding shoe 3 installed below the front end of the coking rod 2, and a transmission rack 4 installed on the bottom surface of the coking rod 2.
[0016] A positioning plate 7 is provided below the coke pusher 2. Support rods 8 are fixedly connected to the top of both ends of the positioning plate 7. A fixed cylinder 9 is fixedly connected to the top of the support rods 8. A limiting rod 10 inserted into the fixed cylinder 9 is fixedly connected to the rear end of the coke pusher head 1. The ends of the positioning plate 7 and the fixed cylinder 9 away from the coke pusher head 1 are both fixedly installed on the coke pusher car.
[0017] The setting of the fixed cylinder 9 and the limiting rod 10 can improve the balance of the thrust of the coking head 2 during the coking process, improve the stability of the coking head 2, and reduce the wear of the coking head 2.
[0018] Both sides of the rear end of the coke pusher head 1 are detachably equipped with L-shaped auxiliary plates 5. A buffer groove is formed between the auxiliary plates 5 and the coke pusher head 1. Multiple fixing strips 11 are fixed to the side of the auxiliary plates 5 and fit against the rear end face of the coke pusher head 1. A sliding groove 12 is opened in the middle of the fixing strip 11. A threaded rod 13 that passes through the sliding groove 12 is fixed to the rear end face of the coke pusher head 1. A positioning nut is installed on the threaded rod 13.
[0019] The auxiliary plate 5 moves outward along the chute 12 so that the end of the auxiliary plate 5 can fit against the inner wall of the carbonization chamber. The coal exposed from the gap between the two ends of the coke pusher head 1 and the inner wall of the carbonization chamber enters the buffer tank under the action of the auxiliary plate 5, thereby effectively reducing the amount of coke remaining in the carbonization chamber.
[0020] A scraper 6 is detachably connected to the bottom cylinder of the rear end of the two auxiliary plates 5. A positioning rod 14 is fixed to the rear end face of the coke pusher head 1. The end of the positioning rod 14 is fixed to the mounting groove 15 that is snapped into the upper part of the scraper 6. The mounting groove 15 is a U-shaped structure, and multiple set bolts 16 are threaded through and threaded to its side. The end of the set bolt 16 abuts against the scraper 6.
[0021] By scraping the residual coke at the bottom of the carbonization chamber with scraper 6, the amount of residual coke inside the carbonization chamber can be further reduced.
[0022] In practical use, the coke pusher head 2 will drive the auxiliary plate 5 and scraper 6 to move when pushing coke, which can effectively reduce the amount of coke left in the carbonization chamber, push the coke more thoroughly, and only the auxiliary plate 5 and scraper 6 need to be replaced periodically, without replacing the coke pusher head, thus reducing the maintenance cost of the coke pusher.
