AI Technical Summary
When traditional cleaning devices clean coke oven doors, tar and other debris harden when they come into contact with water, making them difficult to clean thoroughly. This increases the workload for workers, affects production time and site hygiene, and high-pressure water washing causes water to splash everywhere.
The system employs a combination of ceramic brushes, high-pressure airflow, and a suction port for cleaning. The ceramic brushes remove stubborn coke, while the high-pressure airflow blows away loose coke, which is then collected through the suction port. The system automatically adjusts the brush's fit using position and pressure sensors, achieving automated cleaning.
It enables efficient cleaning of coke oven doors, reduces manual labor, ensures a clean construction site, saves water, and avoids water splashing and flue gas pollution.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of coking processing technology, and in particular to a novel coke oven door cleaning device. Background Technology
[0002] In the coking process, the coke quenching car is one of the key pieces of equipment in coke oven production. It is mainly used to guide red coke from the carbonization chamber into the quenching car during the coke pushing process. In order to ensure the cleanliness of the furnace door on the coke quenching car, a cleaning mechanism is used for positioning and cleaning to avoid tar dust residue from affecting normal use.
[0003] Traditional cleaning devices are equipped with high-pressure water pumps and water tanks, using high-pressure water to clean the furnace doors. However, during the high-pressure water rinsing process, tar and other debris adhering to the furnace doors harden upon contact with water, making thorough cleaning impossible. This necessitates manual cleaning with electric shovels, increasing worker workload and impacting normal production time. Furthermore, incomplete cleaning leads to smoke emanating from the furnace doors, requiring manual extinguishing. The high-pressure water rinsing process also causes water to splash everywhere, severely affecting the cleanliness of the work area. To address these technical problems, we have designed a new type of coke oven door cleaning device. Utility Model Content
[0004] The purpose of this invention is to provide a novel coke oven door cleaning device to solve the problems existing in the background art.
[0005] The technical solution of this utility model is implemented as follows: A novel coke oven door cleaning device includes a support frame, a base vertically connected to the bottom of the support frame, an upper bracket vertically installed on the top of the support frame, a lower bracket vertically installed at the bottom of the support frame, a ball screw installed between the upper and lower brackets, a servo motor connected to the bottom of the ball screw, the servo motor mounted on the base, a ball slider installed on the ball screw, a linear motor installed on the side of the ball slider, a guide rod connected to the linear motor, a ceramic brush installed at the top of the guide rod, a pressure sensor installed between the guide rod and the ceramic brush, a high-pressure airflow nozzle installed on the ball slider, a hose connected to the high-pressure airflow nozzle via a quick connector, the other end of the hose connected to an air source, a dust suction port installed on the ball slider, a high-temperature hose connected to the dust suction port via a flange, the other end of the high-temperature hose connected to a dust removal device, a position sensor installed on the ball slider, and a controller installed on the base.
[0006] Furthermore, bearings are installed at the connection points between the ball screw and the upper and lower supports.
[0007] Furthermore, the base is equipped with casters at its bottom.
[0008] Furthermore, the controller is connected to a servo motor, a linear motor, a pressure sensor, a position sensor, an air source, and a dust removal device via cables.
[0009] The beneficial effects of this utility model are as follows:
[0010] This invention removes stubborn coke using a ceramic brush and blows away loose coke using a high-pressure airflow. The combination of ceramic brush and high-pressure airflow results in better cleaning. The removed coke is collected through a dust suction port to prevent dust pollution and ensure a relatively clean construction site, while also saving water. In addition, the fit between the ceramic brush and the furnace door can be automatically adjusted to improve the cleaning ability of the ceramic brush. Attached Figure Description

Detailed Implementation
[0013] Please see Figure 1 A novel coke oven door cleaning device includes a support frame 1, a base 2 vertically connected to the bottom of the support frame 1, an upper bracket 3 vertically mounted on the top of the support frame 1, and a lower bracket 4 vertically mounted on the lower part of the support frame 1. A ball screw 5 is installed between the upper bracket 3 and the lower bracket 4. A servo motor 6 is connected to the bottom of the ball screw 5 and is mounted on the base 2. A ball slider 7 is mounted on the ball screw 5, and a linear motor 8 is mounted on the side of the ball slider 7. The linear motor 8 is connected to a guide rod 9, and a guide rod 9 is mounted on the top of the guide rod 9. The device includes a ceramic brush 10, a pressure sensor 11 installed between the guide rod 9 and the ceramic brush 10, a high-pressure airflow nozzle 12 installed on the ball slider 7, a hose 14 connected to the high-pressure airflow nozzle 12 via a quick connector 13, the other end of the hose 14 connected to an air source 15, a dust suction port 16 installed on the ball slider 7, a high-temperature hose 18 connected to the high-temperature hose 18 via a flange 17, the other end of the high-temperature hose 18 connected to a dust removal device 19, a position sensor 20 installed on the ball slider 7, and a controller 22 installed on the base 2.
[0014] The ball screw 5 is connected to the upper bracket 3 and the lower bracket 4 by a bearing 21.
[0015] The base 2 is equipped with rollers 23 at its bottom.
[0016] The controller 22 is connected to the servo motor 6, the linear motor 8, the pressure sensor 11, the position sensor 20, the air source 15, and the dust removal equipment 19 via cables.
[0017] In use, the furnace door cleaning device is moved to the furnace door position of the coke quenching car. The servo motor 6, controlled by the controller 22, drives the ball screw 5 to rotate, causing the ball slider 7 to move up and down. At the same time, the ceramic brush 10, the high-pressure airflow nozzle 12, and the dust suction port 16 move up and down. The ceramic brush 10 removes stubborn coke, the high-pressure airflow blows away loose coke, and the dust suction port 16 collects the removed coke to prevent dust pollution. The position sensor 20 measures the position of the ball slider 7 and feeds it back to the controller 22 to control the position of the ceramic brush 10. In addition, the pressure sensor 10 measures the pressure on the ceramic brush 10 to determine the stubbornness of the coke. The linear motor 8 drives the guide rod 9 to move linearly, which can adjust the tightness of the ceramic brush 10 against the furnace door and improve the cleaning ability of the ceramic brush 10. After the cleaning work is completed, the cleaning device is moved to the designated position.
