[0002] Coke ovens can be divided into double fire channel type, two-way fire channel type, and upper flame channel type. In the double fire channel type, the ascending airflow fire channel and the descending airflow fire channel are combined in pairs, and the entire combustion chamber is composed of several groups of double fire channels; in the two-way fire channel type, half of the fire channels in the entire combustion chamber are ascending airflow, and the other half of the fire channels are descending airflow; in the upper flame channel type, the fire channels in the entire combustion chamber are divided into several groups, which are connected to the fire channel groups of the adjacent combustion chambers through the upper flame channel. Usually, a large coke oven uses more than 400-1000 kinds of refractory bricks. The main parts of the coke oven are made of silica bricks. In order to improve the performance of the coke oven, special-shaped bricks are usually also used for masonry.

[0003] like Figure 9-11 As shown, it is a refractory silica brick used in the coke oven corbel area, which has an overall rectangular block structure, an inclined surface arranged obliquely in the middle position, and ribs extending along the width and height directions at the end positions. The cross-section of the ribs is trapezoidal, and the intersection of the width and height directions is an arc structure. Due to the irregularity of the structure of this refractory brick, there is no universal brick-making mold in the prior art to shape it. Therefore, based on the structural characteristics of the above-mentioned refractory bricks, the inventor invented a manufacturing mold that can be used for the molding of the above-mentioned irregular refractory bricks.

DETAILED DESCRIPTION

[0024] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0025] As shown in the figure, a mold for making irregular refractory bricks at the coke oven corbel part includes a bottom plate 1, a front plate 2, a rear plate 3, a left plate 4, a right plate 5 and a top plate 6. The front plate 2, the rear plate 3, the left plate 4 and the right plate 5 are distributed around the bottom plate 1 to form a cavity, and the top plate 6 can be placed in the cavity and has the freedom to move up and down.

[0026] like Figure 5 As shown, one side of the upper surface of the bottom plate 1 has a trapezoidal groove 101 that runs through in the width direction, and the middle position of the upper surface of the bottom plate 1 has a concave V-shaped groove 102, the angle of the V-shaped groove 102 is 90°, and is mainly used to shape the tip of the inclined surface 1202 of the brick blank 12 higher than the surface of the brick blank 12. The V-shaped groove 102 and the trapezoidal groove 1 are perpendicular to each other in the length direction. The upper surface of the bottom plate 1 has a concave step surface 103, and a triangular seat 10 is installed at the position of the step surface 103, that is, the lower plane of the triangular seat 10 matches the step surface 103, so that the middle part of the inclined surface 1202 of the brick blank 12 is formed, and the triangular seat 10 is isosceles A right triangle, the angle between the inclined surface 1202 and the two side surfaces is 45°, and a seat upper plate 7 is provided above the triangular seat 10. Specifically, the lower end of the seat upper plate 7 is inclined at an angle of 45°, so that the connection position between the seat upper plate 7 and the triangular seat 10 forms an angle of 90°, and a movable block 9 is provided on one side of the base close to the trapezoidal groove 101. The inner side of the movable block 9 has a trapezoidal groove 2 901 that matches the cross-section of the trapezoidal groove 101 and is arc-shaped as a whole, that is, the cross-sectional dimensions of the trapezoidal groove 101 and the trapezoidal groove 2 901 are the same. When the movable block 9 is located on one side of the bottom plate 1, the trapezoidal groove 101 and the trapezoidal groove 2 901 are connected to each other.

[0027] It also includes a front vertical plate 8 and a rear vertical plate 11 arranged at the front and rear ends of the triangular seat 10. The inner side of the front vertical plate 8 has a trapezoidal groove three 801 that runs through from top to bottom. The trapezoidal groove three 801 is smoothly connected with the trapezoidal groove two 901 on the movable block 9. The front vertical plate 8 and the rear vertical plate 11 are in contact with the triangular seat 10 respectively. The trapezoidal groove three 801 is connected with the trapezoidal groove two 901, so that the ribs 1201 on the surface of the brick blank 12 are formed by using the trapezoidal groove one 101, the trapezoidal groove two 901, and the trapezoidal groove three 801. In addition, the trapezoidal groove three 801 on the surface of the front vertical plate 8 runs through the up and down directions, so as to avoid interference problems when the top plate 6 moves up and down.

[0028] The two sides of the triangular seat 10 are provided with a notch part 1001 and a notch part 1002 for positioning the front vertical plate 8 and the rear vertical plate 11 respectively, so that during assembly, the front vertical plate 8 is assembled in the notch one position of the triangular seat 10, and the rear vertical plate 11 is assembled in the notch two position of the triangular seat 10. On the one hand, it is convenient for the molding of the brick blank 12, and on the other hand, the front vertical plate 8 and the rear vertical plate 11 can be quickly assembled into place through the two notches.

[0029] One side of the top plate 6 is provided with a yielding portion 601 to prevent interference with the front upright plate 8 and the rear upright plate 11 during lifting and lowering. The yielding portion 601 is an open structure and mainly plays a yielding role to prevent interference problems.

[0030] The back sides of the triangular seat 10, the seat upper plate 7, the front vertical plate 8 and the rear vertical plate 11 are all in contact with the inner side surface of the left side plate 4, so as to position the front vertical plate 8, the movable block 9, the triangular seat 10, the seat upper plate 7 and the rear vertical plate 11.

[0031] When the mold for making irregular refractory bricks for the coke oven bull leg part is in use, the mold is located in the mold cavity of the brick press, wherein the bottom plate 1 is located at the bottom of the mold cavity, and the front end plate 2, the rear end plate 3, the left side plate 4, and the right side plate 5 are located around the mold cavity. Then, the movable block 9, the front vertical plate 8, the triangular seat 10, the rear vertical plate 11 and the seat upper plate 7 are assembled in place in turn, and the weighed refractory material is filled into the mold cavity, and finally the top plate 6 is pressed on the refractory material, and the top plate 6 is pressed by the hammer head of the brick press to form the brick blank 12. After the brick blank 12 is formed, the top plate 6, the seat upper plate 7, the front end plate 2, the rear end plate 3, and the right side plate 5 are taken out first, and then the brick blank 12 is taken out, and finally the remaining parts are taken out to complete the production process of the brick blank 12.
