Problems solved by technology

[0005] The side wall bricks on both sides adopt a three-section combination method. Due to the multi-section combination, there is a large gap between each side wall brick, so the extrusion caused by thermal expansion is reduced, and the existing furnace due to thermal expansion is solved. The phenomenon of cracking caused by extrusion effectively improves the service life of the side wall bricks, thereby ensuring the service life of the high-temperature push plate furnace, less maintenance and long service life

Embodiment 1

[0029] Such as Figure 1 to Figure 3 As shown, the hearth of a high-temperature pusher furnace includes vault bricks 2, corner bricks 3 and bottom bricks 7, the vault bricks 2 are located on the top of the hearth 11, the corner bricks 3 are installed on both sides of the vault bricks 2, and the bottom bricks Brick 7 is positioned at the bottom of hearth 11, also comprises: upper side wall brick 4, and upper side wall brick 4 is positioned at the both sides of furnace 11, and the top of upper side wall brick 4 is installed below corner brick 3, and the upper side wall brick 4 The bottom is provided with an upper card slot 41; the middle side wall brick 5, the top of the middle side wall brick 5 is provided with an upper fixing block 51, and the bottom is provided with a lower fixing block 52, and the middle side wall brick 5 is installed on the top of the upper side wall brick 4. Below, the upper fixing block 51 is inserted in the upper card slot 41, and the middle side wall br...

Embodiment 2

[0036] On the basis of the first embodiment above, a plurality of air intake holes 53 are arranged in a staggered manner.

[0037] A plurality of staggered air inlets 53 allow the shielding gas to enter from multiple positions on the side of the furnace 11 to achieve uniform coverage and greatly improve the uniformity of the shielding gas.

[0038] The air intake holes 53 are not less than two rows, and each row of air inlet holes 53 is not less than two, and the air inlet holes 53 of two adjacent rows are arranged alternately.

[0039] The air inlet holes 53 of each row are arranged at equal intervals along the vertical direction.

[0040] The air inlet holes 53 of each row are arranged at equal intervals along the vertical direction. The air inlet holes 53 are set at equal intervals to facilitate processing, and can ensure the uniformity of the protective gas inlet.

Embodiment 3

[0042] On the basis of any one of the above-mentioned embodiments, it also includes an air intake pipe 8, and there are multiple air intake pipes 8 installed on the air intake holes 53 respectively. Air intake pipe 8 facilitates the control of air intake.

[0043] Valve is housed on the intake pipe 8. Control the opening of the valve to control the intake volume of the protective gas, and then control the uniformity of the protective gas. The valves are gate valves or needle valves. The valves are convenient for adjusting the intake conditions of each intake pipe 8, and are convenient for adjusting the intake volume of the valves according to the sintering quality.

[0044] The valves are gate valves or needle valves.

Abstract

The invention relates to a hearth of a high-temperature push plate furnace. The hearth comprises vault bricks, corner bricks, bottom bricks, upper side wall bricks, lower side wall bricks, upper sidewall bricks, middle side wall bricks and lower side wall bricks, wherein the vault bricks are positioned at the top of the hearth, the corner bricks are mounted on two sides of the vault bricks, the bottom bricks are positioned at the bottom of the hearth, the upper side wall bricks are located on two sides of the hearth, the tops of the upper side wall bricks are installed below the corner bricks, upper clamping grooves are formed in the bottoms of the upper side wall bricks, upper fixing blocks are arranged at the tops of the middle side wall bricks, lower fixing blocks are arranged at the bottoms of the middle side wall bricks, the middle side wall bricks are installed below the upper side wall bricks, the upper fixing blocks are inserted into the upper clamping grooves, a plurality ofair inlet holes are formed in the middle side wall bricks, the tops of the lower side wall bricks are provided with lower clamping grooves, the lower side wall bricks are installed below the middle side wall bricks, the lower clamping grooves are inserted into lower fixing blocks, and the lower side wall bricks are located on the two sides of the bottom bricks. The hearth is formed by splicing three sections and is good in structural stability and convenient to assemble, meanwhile, the protective gas is evenly distributed through the multiple air inlet holes, and the reasonable rate of products is increased.

Description

technical field [0001] The invention relates to a pusher furnace, in particular to a hearth of a high-temperature pusher furnace. Background technique [0002] Existing high-temperature pusher furnaces require larger furnaces when dealing with multi-layer sintering, but the side walls of existing furnaces are prone to cracking and collapse after a period of use, resulting in short service life and high maintenance costs. The equipment was scrapped, and the normal production was affected at the same time. And the higher the furnace, the shorter the service life. When the existing high-temperature pusher furnace is used for multi-layer sintering, there is a problem that the higher the number of product placement layers, the uneven atmosphere in the furnace. Contents of the invention [0003] In order to solve the above problems, the present invention provides a hearth of a high-temperature push plate furnace with a large hearth, long service life, and uniform distribution ...
