However, the traditional blanking tongue structure used at the outlet of the material distribution chamber is thin, the combination with the outlet of the material distribution chamber is not firm enough, it is easy to fall off, and it is also prone to burning cracks and fractures. The service life is short (half a year to nine months), and the accident rate is relatively high. Summary of the Invention

Detailed Embodiments

[0018] The following further illustrates the present utility model in conjunction with the drawings and embodiments, but it shall not be used as a basis for restricting the present utility model.

[0019] Embodiment of the utility model: The blanking tongue structure in the material distribution chamber during alumina production process, including a tongue plate base 1 with an arc-shaped structure and a blanking tongue plate 3. The head end of the tongue plate base 1 is fixedly connected by welding to the material discharge retaining wall steel plate 2 of the material distribution chamber. The blanking tongue plate 3 is supported and fixed on the tongue plate base 1. A flange plate 4 that bends downward is provided at the head end of the blanking tongue plate 3. The blanking tongue plate 3 is hung at the opening of the material discharge retaining wall steel plate 2 of the material distribution chamber through the flange plate 4. Reinforcing plates 5 that protrude upward are provided at the tail and the left and right side ends of the blanking tongue plate 3. Multiple reinforcing plates 5 and the blanking tongue plate 3 form a cavity structure, and concrete 9 is poured in the cavity structure. Both the tongue plate base 1 and the blanking tongue plate 3 are arranged in a structure that slopes downward.

[0020] The support for the blanking tongue plate 3 is realized through the tongue plate base 1. There is only a support relationship between the two, and there is no need for fixed connection (such as welding) between them. The flange plate 4 provided on the blanking tongue plate 3 can facilitate its installation on the material discharge retaining wall steel plate 2 of the material distribution chamber, and the disassembly is also relatively convenient. The multiple reinforcing plates 5 on the blanking tongue plate 3 form a cavity structure that is convenient for pouring concrete 9. The concrete 9 makes the entire blanking tongue structure relatively thick and not easily prone to burning and cracking or breaking.

[0021] A plurality of bosses 6 are provided on the bottom surface of the blanking tongue plate 3, and positioning holes 7 corresponding to the positions of the bosses 6 are provided on the tongue plate base 1. Through the cooperation of the bosses 6 and the positioning holes 7, the blanking tongue plate 3 is limited and fixed to ensure its firm fixation.

[0022] The blanking tongue plate 3 is composed of three separate plate bodies with similar structures, and the left and right plate bodies are mirror-symmetrical structures; one boss 6 is provided at the bottom of each separate plate body, and reinforcing plates 5 that protrude upward are provided at its tail and the left and right side ends. This facilitates the production of the blanking tongue plate 3. If the overall production size and weight are too large, it is not conducive to processing and production, as well as subsequent installation and fixation.

[0023] The three separate plate bodies of the blanking tongue plate 3 are arranged at intervals, and calcium silicate plates 10 are arranged at the intervals between the plate bodies. Such a structural design enables the blanking tongue plate 3 not to require too high dimensional accuracy during production. As long as it is ensured that while the flange plate 4 is hung on the material discharge retaining wall steel plate 2 of the material distribution chamber, the boss 6 can be inserted into the corresponding positioning hole 7, there is no need to worry that due to dimensional accuracy problems between two adjacent separate plate bodies, when the adjacent sides of the two separate plate bodies are fitted, the position of the boss 6 at the bottom of a certain plate body cannot be aligned with the corresponding positioning hole 7, resulting in the problem that the plate body cannot be installed and fixed.

[0024] The bottom of the tongue plate base 1 is also fixedly connected to the material discharge retaining wall steel plate 2 through a reinforcing rib 8 to strengthen the connection between the tongue plate base 1 and the material discharge retaining wall steel plate 2. The support for the tongue plate base 1 can be realized through the reinforcing rib 8, so as to better support the blanking tongue plate 3 through the tongue plate base 1.

[0025] The circumferential wrap angle of the tongue plate base 1 and the blanking tongue plate 3 is 180°, and both the tongue plate base 1 and the blanking tongue plate 3 are arranged at an angle of 45° downward. This structure can better achieve blanking. The length of the tongue plate base 1 is shorter than that of the blanking tongue plate 3 because the tongue plate base 1 only needs to support the front end of the blanking tongue plate 3 and does not need to completely support the blanking tongue plate 3. Therefore, the tongue plate base 1 does not need to be made into a structure with the same length as the blanking tongue plate 3.
