Description

Technical Field

[0001] This utility model belongs to the field of roller kiln technology, specifically relating to an energy-saving glaze firing roller kiln. Background Technology

[0002] Roller kilns, also known as roller bottom kilns, are mainly used for the production of ceramic building materials such as ceramic tiles. Roller kilns are continuous firing kilns, tunnel kilns that use rotating rollers as the carriers of ceramic blanks. Ceramic products are placed on many closely spaced horizontal refractory rollers, and the rotation of the rollers transports the ceramics from the kiln head to the kiln tail, hence the name roller kiln. Roller kilns are generally divided into preheating zones, firing zones, and cooling zones. By controlling the temperature of different zones, the quality of the products can be better guaranteed.

[0003] Currently, there are various problems in the firing of ceramic products in track kilns. For example, after the ceramic products are fired, they enter the cooling zone. The operation of the cooling equipment and the opening of the cooling zone outlet cause a large amount of heat overflowing from the firing zone to be lost, resulting in energy waste. In addition, the cooling effect of ceramic products is generally not good in a short period of time. Furthermore, the preheating zone also needs the equipment to work evenly to improve the temperature conditions. Utility Model Content

[0004] The purpose of this invention is to provide an energy-saving glaze firing roller kiln to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving glaze-firing roller kiln, comprising a roller kiln body, a conveyor roller conveyor disposed above the support platform, the roller kiln body disposed above the conveyor roller conveyor, a hot air pump unit disposed above the roller kiln body, a preheating box disposed above the conveyor roller conveyor at the inlet end of the roller kiln body, and a waste heat recovery and reuse mechanism disposed above the conveyor roller conveyor at the outlet end of the roller kiln body. The waste heat recovery and reuse mechanism includes a cooling box, an induced draft fan, and a combined cover plate. The cooling box is located at the outlet end of the roller kiln body, and the induced draft fan is embedded and fixed at one end of the cooling box. The combined cover plate covers the air outlet of the induced draft fan. An induced draft duct is provided between the combined cover plate and the preheating box. The cooling box is equipped with a heat-enhancing mechanism, which includes a heat-conducting cover plate, heat-conducting columns, and a blower. The blower is embedded and fixed at the other end of the cooling box. The heat-conducting cover plate is located in the inner cavity of the cooling box. The heat-conducting columns are evenly fixed at the middle of the upper end face of the heat-conducting cover plate.

[0006] It should be noted in the solution that one end of the exhaust duct is fixed at the center of one end face of the combined cover plate, and the other end of the exhaust duct is fixed on one end surface of the preheating box.

[0007] It is worth noting that the exhaust duct is connected to the combined cover plate and the exhaust duct is connected to the preheating box.

[0008] Furthermore, it should be noted that both the cooling box and the preheating box have clearance openings at one end, and both the cooling box and the preheating box are connected to the roller kiln body.

[0009] In a preferred embodiment, a closed plate is fixed at the edge of the upper end face of the heat-conducting cover, and a lifting slide is fixed at the middle of the upper end face of the closed plate.

[0010] In a preferred embodiment, the lifting slide is slidably connected to the upper end face of the cooling box, and the closing plate is located inside the clearance opening of the cooling box.

[0011] In a preferred embodiment, a lifting slide is fixed to the upper end face of the cooling box, a damping rubber sleeve is fixed to the inner wall of the lifting slide, and the lifting column is slidably connected in the lifting slide.

[0012] In a preferred embodiment, the cooling box has an inner opening at both ends, and the blower and the induced draft fan are respectively fixed at the two inner openings.

[0013] Compared with the prior art, the energy-saving glaze firing roller kiln provided by this utility model has at least the following beneficial effects:

[0014] (1) By setting up a heat dissipation enhancement mechanism, when ceramic products enter the cooling box, the heat-conducting cover plate is attached to the upper part of the ceramic products to conduct heat and achieve the effect of cooling the ceramic products.

[0015] (2) By setting up a waste heat recovery and reuse mechanism, the blower is used to heat the air by directing it to the heat-conducting cover plate and heat-conducting column, and then the air is introduced into the preheating box through the induced draft fan and induced draft pipe. In this way, the waste heat can be introduced into the preheating box during the cooling process of ceramic products to achieve the purpose of reuse. At the same time, the closed plate covers the inside of the cooling box and reduces the leakage of heat, which can reduce the heat loss in the roller kiln body and the cooling box.
