Description

Technical Field

[0001] This utility model relates to the field of ceramic kiln technology, specifically to a waste heat recovery device for energy-saving ceramic kilns. Background Technology

[0002] A ceramic kiln is a furnace used to fire ceramic objects and sculptures or to fuse enamel onto the surface of metal objects. It can be operated by combustible gas, oil or electricity. However, existing ceramic kilns lack waste heat recovery devices, resulting in the direct emission of heat into the atmosphere, which not only increases environmental pollution but also wastes thermal energy. To address this, we propose a waste heat recovery device for energy-saving ceramic kilns. Utility Model Content

[0003] The purpose of this invention is to provide a waste heat recovery device for energy-saving ceramic kilns to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a waste heat recovery device for an energy-saving ceramic kiln, comprising a ceramic kiln body and a water tank. The inner cavity of the water tank is fixedly connected to two serpentine tubes. A suction fan is fixedly connected to the left end of the top of the water tank, and the input end of the suction fan is connected to the right end of the top of the ceramic kiln body through a pipe. A sleeve is fixedly connected to the middle end of the top of the water tank, and the front end of the left side of the sleeve is connected to the output end of the suction fan through a pipe. The front end of the right side of the sleeve is connected to the lower left end of the front of the ceramic kiln body through a second one-way pipe, and the front end of the top of the sleeve is connected to the serpentine tube at the rear end through a first one-way pipe.

[0005] Preferably, a baffle is bolted to the left side of the ceramic kiln body, first support legs are fixedly connected to all four sides of the bottom of the ceramic kiln body, and second support legs are fixedly connected to all four sides of the bottom of the water tank.

[0006] Preferably, a battery box is fixedly connected to the right end of the top of the water tank, a storage battery is fixedly connected to the bottom of the inner cavity of the battery box, and a charging port is provided on the front of the battery box.

[0007] Preferably, the water tank has a water inlet at the top left front end and a water outlet at the bottom right side, and both the water inlet and the water outlet are threaded with sealing caps at their ends.

[0008] Preferably, a partition is fixedly connected to the front end of the inner cavity of the sleeve, and a fan blade is movably connected to the inner surface of the partition and the sleeve. Two stirring shafts are movably connected to the lower end of the inner surface of the water tank. Stirring blades are fixedly connected to the outer surface of the stirring shafts. The rear end of the fan blades is connected to the stirring shaft at the left end through a single-sided toothed synchronous belt, and the two stirring shafts are connected to each other through a single-sided toothed synchronous belt.

[0009] Preferably, the inner surface of the second one-way tube is provided with a solenoid valve, the two serpentine tubes are connected by a connecting pipe, the rear end of the sleeve cavity is fixedly connected to a stator, and the rear end of the fan blade is fixedly connected to a rotor.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model involves feeding ceramics into the ceramic kiln body and fixing the baffle to the surface of the ceramic kiln body by tightening bolts with an external wrench. Turning on the suction fan allows hot air to be transported through pipes into the cavity formed by the sleeve and the baffle. When it is necessary to accelerate the air circulation rate inside the ceramic kiln body, the solenoid valve is opened, leaving a gap between the baffle and the ceramic kiln body. Some of the hot air entering the inner cavity of the sleeve will enter the ceramic kiln body through the second one-way pipe, thereby increasing the air circulation rate inside the ceramic kiln body. The remaining hot air is transported to the rear coiled tube through the first one-way pipe and enters the front coiled tube with the help of the connecting pipe, and finally exits from the output end of the coiled tube, thereby performing heat exchange treatment on the water in the water tank.

[0012] 2. When hot air enters the sleeve, it drives the fan blades to rotate, and with the cooperation of the single-sided toothed synchronous belt, it drives the stirring shaft to rotate, thereby stirring the water and further improving the heat exchange effect. At the same time, the rotation of the fan blades will drive the rotor to rotate, and with the cooperation of the stator, it will generate electrical energy and store it in the battery, thereby achieving the purpose of self-generation, effectively reducing the consumption of mains power and meeting the national energy conservation and emission reduction requirements.
