Description

Technical Field

[0001] The utility model relates to the field of burner nozzle cleaning equipment, in particular to a self-made burner nozzle cross-section coking cleaning device. Background Art

[0002] In order to achieve energy conservation and carbon reduction in high-yield and low-energy-consuming cement enterprises, cement enterprises have to reduce production costs and continuously replace high-energy-consuming equipment. In order to reduce production costs, reduce carbon emissions and improve clinker quality, most companies choose high-thrust low-nitrogen burners. Due to the different models of burners from different manufacturers, the effects vary greatly. In the early stage, our company used silver flame burners, which had low thrust, unfocused flames, poor clinker granulation, and light per liter weight. In order to improve the quality of clinker and increase the flame temperature, we chose to replace Chengdu Jianeng's high-thrust low-nitrogen burners. After using them, the quality of clinker was greatly improved, but the burner reasoning was large. The end face of the burner nozzle cokes quickly and is relatively hard. Ordinary steel pipes need to be cleaned three times per shift, which greatly increases the labor intensity and safety risks of the position. In order to reduce the labor intensity and safety risks of the position, a rotary kiln coke cleaner is now used, which does not require opening the rotary kiln. The scraper swings and fits with the end face, and then rotates the scraper to scrape off the coke on the end face of the burner. However, the scraper has an obvious defect, that is, the scraper is hinged to the rotating shaft. When encountering a relatively hard coke block, the scraper cannot scrape off the relatively hard coke block. At the same time, the scraper also needs to change the burner structure, which is costly. Summary of the invention

DETAILED DESCRIPTION

[0017] The present invention is now further described with reference to the accompanying drawings.

[0018] like Figure 1-5 As shown, a self-made burner cross-section coking cleaning device comprises an insertion rod 1, an anti-dropping rod 2 and a scraper 3, wherein the anti-dropping rod 2 perpendicular to the insertion rod 1 is installed at the left end of the insertion rod 1, and a plurality of scrapers 3 are installed at the right end of the insertion rod 1;

[0019] There are three or more scrapers 3, and the scrapers 3 are installed in a circular array at the end of the insertion rod 1. The scrapers 3 are welded to the outer wall of the right end of the insertion rod 1. The ends of the scrapers 3 are tilted inward and merged. The scrapers 3 form a cone, and the end faces of the scrapers 3 are flush. When the insertion rod 1 rotates, the end face of the scraper 3 contacts the end face of the burner, so that the coke on the end face is cleaned by the scraper 3, and the side 1 of the scraper 3 can clean the coke on the inner wall of the burner shell. Compared with the scraper extending out from the center of the burner, the scraper contacts the end surface of the burner. When the coke block is relatively hard, the scraper cannot scrape it clean. The top of the scraper of the present application is an inclined surface (the scraper 3 is close to the coke block in the rotating state. Since the scraper 3 is an inclined surface, the scraper 3 first scrapes the surface of the coke block, and then scrapes the coke block from the outside to the inside little by little, so as to scrape off the relatively hard coke block). The scraper 3 rotates by the rotation of the extension rod 1, and the scraper 3 removes the relatively hard coke block by rotating;

[0020] A suspension component 4 is installed on one end of the insertion rod 1 located on the scraper 3, and the end of the insertion rod 1 is suspended on the burner through the suspension component 4. The insertion rod 1 is slidably connected with the suspension component 4, that is, the right end of the insertion rod 1 is suspended on the burner. Since the insertion rod is relatively long, the strength of holding it for a long time to hang the decoking block is relatively large. The right end of the insertion rod is suspended, which reduces the strength of the staff holding the insertion rod. In this way, the staff only needs to have relatively large physical strength when hanging the suspension component 4 on the burner, and the strength is reduced when hanging the decoking block.

[0021] The suspension assembly 4 includes a clamping assembly 5 and a mounting ring 11, and the clamping assembly 5 is installed on the outer circumference of the mounting ring 11 in a hinged manner. The clamping assembly 5 includes a clamping arm 6 and an adjusting ring 10, wherein a plurality of clamping arms 6 are hinged on the mounting ring 11, and a positioning inclined surface 7 is provided on the inner side of the other end of the clamping arm 6, and the positioning inclined surface 7 is in contact with the outer wall of the burner shell, and a long strip-shaped adjusting groove 8 is provided on each clamping arm 6. An adjusting ring 10 is provided on the right side of the mounting ring 11, and the adjusting ring 10 extends into the adjusting grooves 8 of the plurality of clamping walls 6. An adjusting bolt 9 is provided between the mounting ring 11 and the adjusting ring 10. The adjusting bolt 9 passes through the mounting ring 11 and is threadedly matched with the mounting ring 11. The tail of the adjusting bolt 9 is mounted on the left side of the adjusting ring 10 through a bearing. The spacing between the mounting ring 1 and the adjusting ring 10 is adjusted by rotating the adjusting bolt 9, so that the inclination of the clamping arm 6 can be adjusted. The multiple clamping arms 6 clamp the burner housing. Since the right end face of the clamping arm 6 is a positioning inclined surface 7 that fits the burner housing, the mounting ring 11 is clamped on the burner housing through the clamping arm 6. A lifting sleeve 12 is installed on the top of the mounting ring 11 by means of rotational connection (a rotating shaft is fixed to the outer wall of the lifting sleeve 12 by means of welding, a through hole for inserting a bearing is opened on the left side surface of the mounting ring 11, a bearing is embedded in the through hole, and the rotating shaft is inserted into the bearing and rolled for welding, so that the lifting sleeve 12 can swing), a lifting rod 13 is inserted into the lifting sleeve 12, a rotating sleeve 14 is fixed to the bottom of the lifting rod 13 by means of welding, the insertion rod 1 passes through the rotating sleeve 14, and the insertion rod 1 and the rotating sleeve 14 rotate relative to each other. A one-way sliding assembly 15 is provided between the lifting rod 13 and the lifting sleeve 12, and the lifting rod 13 can only move upward; when cleaning the coke, first move the lifting rod 13 downward to the lowest position, clamp the mounting ring 11 on the burner housing, operate the insertion rod 1 to swing, and at the same time, the insertion rod 1 rotates. When the insertion rod 1 swings, the scraper 3 cleans the burner end face and the inner wall of the burner housing, and then the insertion rod 1 is pushed upward, and the insertion rod 1 is continued to be swung to remove the coke, and the coke is removed from the entire burner end face by gradually rising.

[0022] The one-way sliding assembly 15 includes an embedding groove 16 and a sliding locking pin 17, wherein the embedding grooves 16 are arranged at equal intervals on the outer periphery of the lifting rod 13, the top surface and the bottom surface of the embedding groove 16 are a plane and an inclined surface respectively, and an installation groove 18 is opened on the inner wall of the lifting sleeve 12, and a swingable locking pin 17 is installed in the installation groove 18 (the locking pin 17 is fixed to the swing arm by welding, and the bottom of the swing arm is installed in the installation groove 18 by hinged manner, and the hinge position of the swing arm and the installation groove 18 is located at the bottom of the installation groove), and the locking pin 17 is embedded in the embedding groove 16 in a swinging manner, and the locking pin 17 is against the plane of the embedding groove 16, so that the lifting rod 13 is prevented from descending and the lifting rod 13 is realized. One-way ascent, when the lifting rod 13 needs to be descended, the lifting rod is rotated 180° upward, and then the lifting rod 13 is lifted upward.

[0023] There are two anti-falling rods 2 and the two anti-falling rods 2 are welded on the holding sleeve 20, the holding sleeve 20 is sleeved on the insertion rod 1, the holding sleeve 20 is rotatably connected to the insertion rod 1 (a bearing is sleeved on the left end of the insertion rod 1, and the holding sleeve 20 is sleeved on the bearing), a motor 21 is installed on the anti-falling rod by bolting, and the output shaft of the motor 21 is connected to the insertion rod 1 by welding, so that the rotation of the insertion rod 1 is realized, and a transparent windshield 22 is installed on the end of the holding sleeve 20 away from the anti-falling rod by bolts, and the windshield 22 blocks hot air.

[0024] The scraper 3, the extension rod 1, the mounting ring 11 and the suspension assembly 4 in the present application are all made of heat-resistant steel plates and heat-resistant steel pipes.
