Description

Cleaning system of industrial oven doors or oven door jambs using high speed spray rotary nozzle}

The present invention relates to an industrial cleaning device, and more particularly, to a cleaning device for cleaning the industrial oven door or the mold of the oven door by water injection.

A typical example of an industrial oven is a coke oven that uses coal to make fuel coal in a steel mill. Hereinafter, the present invention will be described using a coke oven as an example. However, the technical idea of the present invention is not limited to coke ovens, but can be widely applied to industrial ovens.

Generally, coke factories in steel mills are crushed and blended with various types of raw coal in a coke oven in order to produce economical coke of a grade suitable for the operating conditions, and the fuel coal is heated by indirect heat of about 1,320 ° C for about 17 hours. After distillation, it was supplied to a steel mill and a sintering plant.

Here, the coke oven is mainly constructed of refractory bricks and includes a carbonization chamber and a combustion chamber.In operation, the raw material coal is charged into the carbonization chamber to block the air, and the mixing gas (BFP + COG = 101) is combusted in the combustion chamber. This is where the operation to dry the fuel coal with indirect heat.

A large amount of tar (T) and carbon (C) is inevitably generated during the operation of carbonizing the coal in the coke oven. In this case, as illustrated in FIG. 1, the softening part 7 and the sealing strip part 4 of the carbonization chamber door 10 are adhered and formed in the form of tar (T) and carbon (C), and the oven is used for the next operation. When the door 10 of the door 10 is closed, the deposits 2 and 6 formed on the door 10 lower the airtight action, so that gas leakage may occur outside the carbonization chamber.

In addition, the carbon (C) bonded to the door 10 is fused with the coke in the drying process, causing a problem of breaking down the hot red coke when the oven door 10 for the extrusion operation after the drying is removed.

In this case, after the heating operation is finished, it is necessary to clean the door and the door frame of the oven, when a person is directly put into the field to clean and exposed to various harmful substances harmful to the human body.

Conventionally, many apparatuses for cleaning by using a door cleaning device of a transfer car and a pusher, which are coke oven moving cars, have been proposed in order to improve work efficiency and reduce an operator's risk.

According to the prior art as described above, the contaminants of the door or the door frame are mostly removed by a scraper. However, scrapers not only have a limited operating area, but also have problems that are inadequate for performing sophisticated tasks.

The moving means 14 have a rotating wheel 24 which rotates along a continuous tube 22 formed along the track 12.

However, according to the present invention, due to the direct pressure injection method, there is a problem that a large amount of water by high pressure is required to remove tar or carbon.

In addition, there is a risk that the worker is exposed to harmful environment by the operator directly involved in the removal operation in order to completely remove the tar or carbon.

In addition, there is a problem that the movement of the cleaning moving means is hindered by the accumulation of foreign matter removed while the cleaning moving means moves on the tube surface.

It is an object of the present invention to solve the problems of the prior art, to provide an economical cleaning device using a small amount of water and low pressure.

Another object of the present invention is to provide an automated cleaning device that enables a worker to perform work without entering the workplace.

It is still another object of the present invention to provide a cleaning device that performs a cleaning operation smoothly by the cleaning moving means by frequently removing foreign matter accumulated in the moving path of the cleaning moving means.

The cleaning device according to the present invention for achieving the technical problem of the present invention is a cleaner (cleaner) and a plurality of moving wheels for removing deposits on the surface of the oven door (doorven) and the door frame (door frame) by spraying the washing water The cleaner conveying means for conveying the cleaner by means of a continuous pipe for guiding the rotation of the moving wheels and a closed track formed with pin racks at predetermined intervals along one side, the cleaner conveying means provides a driving force In a washing apparatus for an industrial oven door and door frame in which a provided pin wheel rotates in conjunction with the pin rack, the cleaner moves in the axial direction of the moving wheel.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the present invention will be described in detail. Like reference numerals in the drawings denote components that perform the same function.

Figure 3 is a perspective view showing a preferred example of the washing apparatus according to the present invention, Figure 4 shows a cleaner and conveying means having a rotary spray nozzle.

3 and 4, the cleaning apparatus according to the present invention has a cleaner 100, a cleaner conveying means 200, and a closed truck 300. The cleaner 100 removes deposits on the sealed outer surfaces of the industrial oven door and the door frame by spraying the washing water.

The cleaner conveying means 200 carries the cleaner 100 by means of a plurality of moving wheels 202, and the closed track 300 consists of a continuous tube 304 for guiding the rotating wheels 202. A pin rack 302 is formed around the closed track 300.

A pin wheel 210 is formed in the cleaner transport means 200 to rotate around the closed track 300 in conjunction with a pin rack 302. At this time, the driving force providing means 208 for providing a driving force to the pin wheel 210 is provided. The driving force providing means 208 preferably employs a hydraulic motor.

On the other hand, the plate 306 is arranged in a shape that can pass through the movement wheel 202 at regular intervals along the closed track (300). The moving wheel 202 attached to the cleaner conveying means 200 passes through the plate 306 at predetermined distances while moving along the continuous tube 304.

On the other hand, the cleaner 100 of the present invention performs a cleaning process by the washing water, similar to the cleaning device shown in FIG. However, the conventional washing apparatus performs a washing operation by simply spraying water directly through a spray nozzle.

The cleaner 100 of the washing apparatus according to the present invention has a rotating spray nozzle 130 so that the washing water can be sprayed by the rotation. Referring to FIG. 4, the lance 102 is formed in the axial direction of the moving wheel 202 to receive and transmit the high pressure water. The rotary spray nozzle 130 serves to adjust the high pressure water to be rotated at the end of the lance (102).

As shown in FIG. 5, the rotary spray nozzle 130 includes a nozzle connection part 132, a tube part 134, an injection hole 136, and a nozzle exterior part 138.

The nozzle connecting portion 132 is configured to couple the tube portion 134 to the lance 102 to be rotatable.

The tube portion 134 is formed of a steel tube is configured to move the high pressure water delivered from the lance 102 to the injection hole 136.

The injection hole 136 is connected to the end of the tube portion 132 to inject a high pressure water in the configuration of the nozzle outer portion 138 so that the hole for injecting high pressure water is inclined at a predetermined angle in the direction in which the high pressure water is injected Is coupled to.

The injection port 136 is coupled to the nozzle housing 138 so that the hole for injecting the high pressure water toward the opposite direction to rotate the nozzle housing 138 when viewed from the direction in which the high pressure water is sprayed as shown in FIG. Likewise, the nozzle exterior part 138 rotates.

In an embodiment, if the nozzle exterior part 138 is configured to rotate in a counterclockwise direction, the injection hole 136 has an end for spraying the high pressure water of the injection hole 136 when viewed from the direction in which the high pressure water is injected as shown in FIG. It is coupled to the inside of the nozzle outer portion 138 to be inclined at a predetermined angle toward the clockwise direction to rotate the nozzle outer portion 138 by receiving a force in a counterclockwise direction with the ejection pressure of the high pressure water while spouting the high pressure water clockwise. .

The nozzle exterior part 138 has a structure in which the tube part 134 and the injection hole 136 are built, and one end of the nozzle exterior part 138 is connected to the lance 102 through the nozzle connection part 132, and the injection hole 136 is provided inside the other end. Rotating in the opposite direction in which the high-pressure water is injected to the pressure that the high-pressure water is injected from the injection port 136 in a combined configuration so that the high-pressure water is sprayed in a circular shape.

On the other hand, the rotary wheels 202 of the cleaner conveying means 200 of the present invention are arranged in sequence along the moving direction in parallel. In this case, the rotating wheel 202 forms a concave continuous groove around the wheel to correspond to the convex side of the pipe so as to move along the continuous pipe.

The pipe 304 is continuously arranged along the closed track 300. It is preferable that a pair of continuous pipes are arranged to form an upper layer and a lower layer, respectively. The spacing of the continuous pipes of the upper layer may be narrower than the spacing of the continuous pipes of the lower layer. In this case, the inner side of the rotating wheel is formed so as to correspond to the convex surface of the lower continuous pipe, and the outer side is formed with concave grooves to correspond to the convex surface of the upper continuous pipe.

Meanwhile, the rotating wheel 202 of the present invention has at least three wheels. The force acting on the cleaner transport means 200 when the cleaner transport means 200 rotates the closed track 300 includes the sum of the force in the traveling direction and the center force of the track due to the reaction of the sprayed water (centrifugal force or Gravity and other forces will not be considered).

When the conveying means rotates the track while spraying the high pressure washing water with two rotating wheels as in the related art, the sum of the force received by the cleaner conveying means is biased in a direction perpendicular to the traveling direction.

In particular, the greater the pressure injected, the greater the contribution of the force due to the reaction, so that the cleaner transport means 200 becomes difficult to stably transport the cleaner 200. Therefore, it may be characterized by having at least three rotary wheels for the purpose of minimizing the reaction generated from the spray of the washing water.

In addition, since the present invention employs a rotary spraying method instead of direct spraying, efficient washing can be performed under low pressure, thereby minimizing external force in the lateral direction acting on the cleaner transporting means 200.

Therefore, when the cleaner 100 performs the cleaning operation as the cleaner transport means 200 progresses, the cleaning operation may be stably performed along the closed track without being greatly influenced by external force.

7 illustrates a specific example of the lance 102 in which the rotary spray nozzle is formed, and shows that the cleaner 100 further includes auxiliary lances 112 and 122. Referring to FIG. 4, the auxiliary lances 112 and 122 protrude from the side of the lance 102 and form injection nozzles 114, 116, 123, and 126 at their ends.

In the present invention, the clear conveying means 200 performs a cleaning operation while rotating around the closed track 300, wherein the moving wheels 202 rotate while moving in conjunction with the pipe. However, when the cleaning operation is performed, foreign matters separated from the oven door or the door frame may fly and be adsorbed onto the pipe, thereby preventing the movement of the cleaning device.

In particular, when such foreign matter is stuck for a long time, in order to perform the cleaning operation smoothly, a time and economic difficulty of providing a separate device for removing the stuck foreign matter is raised. Therefore, the present invention can solve the above problems by forming the auxiliary lances 112 and 122 protruding on the side of the lance 102 to remove the foreign matter adsorbed to the tube immediately.

On the other hand, when traveling with three or more rotary wheels as in the present invention, the cleaner transport means should be able to cope with the corner curved surface of the closed track. To this end, the wheel located at the leading end or the rear end of the traveling wheel 202 in the traveling direction has a vertical axis 206 connected perpendicularly to the rotation axis 204 at the center of the rotation axis 204, and the cleaner carrying means 200 is closed. When rotating along the corner curved surface of the track 300, the vertical axis 206 may be configured to be bent by elasticity corresponding to the curvature of the curved surface.

The auxiliary lance shown in FIG. 7 has two auxiliary lances 112, 122, each auxiliary lance having a pair of nozzles 114, 116; 123, 126, respectively. At this time, the nozzle is preferably configured such that the washing water is directed so as to be perpendicular to the outer surface of the tube.

That is, the auxiliary lances 112 and 122 formed by FIG. 7 are a preferred configuration for cleaning the outer surface of the tube formed continuously in the upper layer and the lower layer described above. However, the auxiliary device for implementing the technical idea of the present invention is not limited to the configuration shown in FIG.
