[0027] The technical scheme of the utility model will be further described below in combination with the embodiments.
[0028] As Figure 1 , 2 shown, a hollow brick for assisting heat dissipation, comprising a brick body, characterized in that: the brick body is a columnar structure in the front-rear direction, the brick body has a heat evacuation cavity 1 penetrating in the front-rear direction in the center, a through hole 2 is arranged on the lower surface of the brick body, and the through hole is in communication with the heat evacuation cavity and the outside of the lower surface of the brick body.
[0029] Further, the brick body has a right mounting portion 3 and a lower mounting portion 4, the right mounting portion is a structure protruding to the right, and the lower mounting portion is a structure protruding downward.
[0030] The arrangement of the right mounting portion and the lower mounting portion can make the hollow brick be mounted more closely on a tunnel kiln, as Figure 3 shown.
[0031] Further, as Figure 2 shown, the brick body has an upward thickening portion 5 and a left thickening portion 6.
[0032] The arrangement of the thickening portions can make the cross-sectional area of the hollow brick larger, make the area of the heat evacuation cavity larger, make the heat evacuation faster, and make the strength of the hollow brick larger.
[0033] As Figure 3 , 45, 6 A tunnel kiln capable of recovering heat, comprising a kiln body, wherein the kiln body is a structure constructed of bricks 7 laid in a front-to-back direction and has a tunnel cavity 8 in a front-to-back direction, characterized in that: the aforementioned heat dissipation hollow bricks are laid and installed at the upper left corner of the kiln body, the heat dissipation hollow bricks are installed at the upper left corner of the kiln body through a right mounting part and a lower mounting part, after the heat dissipation hollow bricks are installed, the through holes 2 of the bricks connect the heat exhaust cavity 1 and the tunnel cavity 8 on the lower side of the bricks; there are multiple heat dissipation hollow bricks, which are arranged and laid in a front-to-back direction, and the heat exhaust cavities of the front and back heat dissipation hollow bricks are connected front and back to form a heat exhaust channel 9.
[0034] There are also plugging bricks used in conjunction with the tunnel cavity. There are two plugging bricks, namely the front plugging brick 10 and the rear plugging brick 11. The front plugging brick can be inserted into and block the front end of the heat exhaust channel, and the rear plugging brick can be inserted into and block the rear end of the heat exhaust channel.
[0035] The rearmost periphery of the heat exhaust channel has a protruding eave 12.
[0036] Instructions for use: This tunnel kiln is used when the air temperature inside the kiln is too high and needs to be lowered, or when the tunnel kiln has finished production and the hot air inside needs to be collected. Before use, block the very front of the heat exhaust channel with a plugging brick, and then use the flexible hose 13, such as... Figure 7 One end of the flexible tube is fitted onto the protruding edge of the heat exhaust channel, and the other end of the flexible tube is connected to the fan 14. The fan extracts and collects the hot air in the heat exhaust channel and extracts the heat from the entire tunnel cavity and sends it to where it is needed. This serves to reduce the air temperature in the tunnel kiln and collect the hot air after production is completed. When it is not necessary to extract heat, the two ends of the heat exhaust channel are sealed with front and rear blocking bricks to prevent heat loss.
[0037] Furthermore, a filter screen is installed at the two through holes.
[0038] This ensures that the collected hot air is of higher quality and free of dust.
[0039] To elaborate further, such as Figures 8-10 As shown, the right mounting part 3 of the hollow brick has a groove 15 in the front-to-back direction. Correspondingly, the part where the kiln body and the right mounting part of the hollow brick are laid together has a corresponding first protrusion 16. When the hollow brick is laid on the kiln body, the groove of the right mounting part and the first protrusion of the kiln body are combined. The lower mounting part 4 of the hollow brick has a groove in the front-to-back direction. Correspondingly, the part where the kiln body and the lower mounting part are laid together has a corresponding second protrusion 17. When the hollow brick is laid on the kiln body, the groove of the lower mounting part and the second protrusion of the kiln body are combined.
[0040] This makes the hollow bricks more firmly and securely installed on the kiln.
[0041] The above merely describes preferred embodiments of the present application, but does not limit the present application in any form. Any person skilled in the art can make some changes or modifications to the above disclosed technical contents to obtain equivalent embodiments with equivalent changes, without departing from the technical solution of the present application. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present application still falls within the scope of the technical solution of the present application.
