JPH07102257A - Cleaner for tar pan of coke oven - Google Patents

Abstract

PURPOSE:To obtain a tar pan cleaner which facilitates inspection, etc., because of a simple constitution and ensures cleaning even if the positions and angles of tar pans vary with throats. CONSTITUTION:This cleaner has a constitution wherein two cylinders 2,3 are attached in front and in. rear with the bottoms up to the rear of the lower part of a throat cleaner and wherein a tar pan scraper 12 is connected below these cylinders in such a manner that it moves up and down and back and forth through a single pivot 6.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coke oven tar pan cleaner.

[0002]

2. Description of the Related Art As a tar pan cleaner for a coke oven, Japanese Patent Laid-Open No. 55-71788 and 3-558
38, JP 58-671, JP 62-2
There is a publication of 39071. In all of these, the tar pan scraper is moved up and down and moved back and forth using the up and down movement of the sheet cleaner or a single cylinder.

[0003]

However, the position and angle of the tar pan may be slightly different depending on the furnace opening. Therefore, a single vertical moving body or a single cylinder is used as a power source to move the tar pan cleaner up and down. In the conventional technology of moving forward and backward, it strongly touches the tar pan,
There is a problem in that the tar pan and the tar pan cleaner are damaged due to a portion that does not come into contact with the tar pan or a portion that remains uncleaned occurs.

[0004]

According to the present invention, two cylinders are attached to the lower rear side of a furnace mouth cleaner in the front and rear direction, and the two cylinders are attached downward. The problem is to solve the problem by connecting a tar pan scraper.

[0005]

According to the present invention, when cleaning the furnace opening of the coke oven with the furnace opening cleaner, two cylinders mounted downward and forward and backward on the lower back side of the frame of the furnace opening cleaner are operated to form a single pivot shaft. The tar pan scraper is moved up and down and moved back and forth across the pin to clean the tar pan.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments will be described below with reference to the drawings.

A support frame 1 is provided on the lower back side of the frame a of the furnace mouth cleaner, two cylinders 2 and 3 are attached to the front and rear of the support frame 1 downward, and a tip of a rod 4 of one cylinder 2 is attached. A lateral pivot shaft 6 and a shaft 7 with a spring cylinder 7a are attached downward from the pivot shaft 6 with a short lever 5 connected to each other, and the tip of the spring cylinder 7a is pivotally attached 9 to the middle of the scraper shoe 8 toward the rear. Rod on the other cylinder 3
10, L-shaped lever 11 is attached with the axis 6 in between, L-shaped lever
The tip of 11 is pivotally attached to the rear end of the scraper shoe 8.
The scraper shoe 8 is composed of two parallel plates 8a and 8b, and a tar pan scraper 12 is obliquely attached to the front surface of an upward slant plate 8c which is provided at the tips of the parallel plates 8a and 8b. 13 is tar bread.

The furnace port cleaner is advanced to the cleaning position of the furnace port 14, and the cylinders 2 and 3 are operated to move the tar pan scraper 12 up and down and back and forth during the cleaning of the furnace port and before and after cleaning the tar pan 13. Clean the top.

That is, the tar pan scraper 12 is shown in FIG.
When the cylinder 2 is actuated from the phantom position b of Fig. 2 and the rod 4 is extended, the pivot 6 and the shaft 7 with the spring cylinder 7a move downward with the short lever 5 in between and the tar pan scraper 12 and tar pan 13
When the cylinder 3 is actuated and the rod 10 is contracted by operating the cylinder 3, the L-shaped lever 11 pivots backward with the pivot shaft 6 in between, and the tar pan scraper 12 is moved to the tar pan.
From the base of 13 to the position b on the tip, move the tar pan 13
The top will be cleaned.

Upon completion of the cleaning, the tar pan scraper 12 is moved upward by the reverse operation of the cylinders 2 and 3 and returned to the forward position, and is separated from the coke oven furnace opening as the furnace opening cleaner is retracted.

[0011]

As described above, according to the present invention, the tar pan scraper is vertically moved and moved forward and backward by the two cylinders attached to the lower rear side of the frame of the furnace mouth cleaner to clean the tar pan. Therefore, even if the position and angle of the tar pan differ slightly depending on the furnace opening, the tar pan is thoroughly cleaned without causing excessive contact or a non-contact point due to the operation of connecting the two cylinders. However, the tar pan and the tar pan cleaner are not damaged.

Since the tar pan scraper is attached with two cylinders sandwiching a single pivot, there is an effect that the structure is extremely simple and inspection and the like are easy.
