[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 , an embodiment provided by the utility model:

[0022] A pit-type firing chamber device includes a fixing base 1, which is fixed to the ground by casting. A first firing chamber body 5, a second firing chamber body 6, a third firing chamber body 7, and a fourth firing chamber body 8 are cast and fixed to the upper end of the fixing base 1 in sequence. A lifting lug 17 is provided on each firing chamber body. The firing chamber bodies are connected to form an integral pit-type firing chamber by connecting bolts in order from bottom to top. An internal casting device 12 is provided inside the integral pit-type firing chamber.

[0023] A nozzle port 3 is provided on the outside of the first kiln firing chamber main body 5, and a furnace door 4 and a fire viewing mirror 2 are provided at the nozzle port 3. A ladder 9 is fixedly connected to the outside of each kiln firing chamber main body in sequence. A temperature sensor 10 and a pressure sensor 11 are provided on the outer wall of the first kiln firing chamber main body 5 close to the ladder. An inspection platform 13 is provided on the ladder 9 close to the end of the third kiln firing chamber main body 7. A hot smoke temperature sensor 14, a hot smoke pressure sensor 15 and a hot smoke flow meter 16 are provided on the outer wall of the fourth kiln firing chamber main body 8.

[0024] As a further feature of the present invention, the fourth kiln firing chamber body 8 is cylindrical in height, and the third kiln firing chamber body 7 is configured as a converging cone-shaped structure.

[0025] Existing technologies such as Figure 2 Shown are:

[0026] The bottom foundation 102 is supported by side support frames 103, refractory bricks 105 and top support frames 106, and is externally reinforced by embedded steel plates 101, side support frames 103 and top support frames 106. A burner 104 is provided in the middle of the refractory bricks 105, and the burner 104 is connected to a smoke exhaust port 108. A furnace door structure 107 is provided on the outside of the burner 104. The bottom foundation 102 is cast by using refractory cement. In order to prevent the refractory bricks 105 from being deformed and collapsed due to long-term use, embedded steel plates 101, side support frames 103 and top support frames 106 are used for external reinforcement support.

[0027] However, there are many problems with the existing technology, such as:

[0028] 1. When used under heat for a long time, the top refractory bricks are prone to collapse and the side refractory bricks are prone to cracking;

[0029] 2. The combined construction cost of the refractory bricks 5 and the support frame is very high;

[0030] 3. The outer dimensions of the combustion chamber are relatively large, and the top structure causes a large resistance to smoke exhaust at the smoke exhaust port 8, which is not conducive to smoke exhaust;

[0031] 4. The construction period is relatively long;

[0032] 5. Construction must be carried out at the project site, affecting the overall project progress;

[0033] 6. It occupies a very large area;

[0034] 7. After the project site is changed, the combustion chamber will be dismantled and scrapped, and its reuse value is extremely low;

[0035] 8. After long-term use, smoke is likely to leak between refractory bricks, and maintenance is complicated.

[0036] The utility model fixes the combustible gas burner at the burner mouth 3, and the combustible gas burner sprays flames to burn inside the kiln combustion chamber. The combustion temperature is detected in real time by the combustion temperature sensor 10, and the combustion pressure is detected in real time by the combustion pressure sensor 11. The internal flame combustion situation is observed through the fire viewing mirror 2. The internal pouring device 12 has the functions of absorbing and storing heat. If the combustible gas burner is extinguished and its supporting flame sensing device fails to detect the extinguishing situation, the internal pouring device 12 reaches the ignition temperature of the combustible gas, and the combustible gas will burn close to the internal pouring device 12 to avoid the combustible gas from burning. Gas gathers in the kiln combustion chamber and suddenly ignites, creating a dangerous situation of explosion; the hot smoke generated travels along the first kiln combustion chamber body 5, the second kiln combustion chamber body 6, and the third kiln combustion chamber body 7 to the fourth kiln combustion chamber body 8, where the hot smoke is detected in real time by the hot smoke temperature sensor 14, the hot smoke pressure sensor 15, and the hot smoke flow meter 16; since the structure has a high height and the structure of the third kiln combustion chamber body 7 is a converging cone, the hot smoke is very easy to be discharged from the smoke outlet of the fourth kiln combustion chamber body 8. When the project site is replaced, it only needs to be dismantled, transported and reinstalled for repeated use.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
