Technical Field

[0001] The utility model relates to the technical field of ceramic production equipment, in particular to an energy-saving ceramic kiln. Background Art

[0002] A kiln or furnace is a furnace used to fire ceramics and sculptures or to fuse enamel to metal. It is usually made of brick and stone, and can be made into various sizes according to the needs. It can be powered by gas, oil or electricity. Electric kilns are easier to control the temperature than kilns using gas and oil, but some potters and sculptors believe that the temperature of electric kilns rises too quickly.

[0003] Faced with the decreasing reserves of traditional energy and the soaring energy prices, the energy conservation situation in the ceramic industry is very severe. The ceramic industry has always been a high-energy-consuming industry with a relatively high energy consumption cost ratio. Reducing energy costs and enhancing the market competitiveness of corporate products have become the focus of national energy conservation and environmental protection requirements and corporate cost control. The high ceramic unit consumption index seriously restricts the survival and development of enterprises. At present, the efficiency of general ceramic kilns on the market is not very high. Since the heat generated by the kiln during use is wasted and cannot be used reasonably, the practicality of the kiln is greatly reduced, and the cost of using the factory is also greatly increased.

[0021] Reference Figure 1-Figure 2 As shown, a preferred embodiment of the utility model is an energy-saving ceramic kiln, comprising a furnace body 1, an air outlet pipe 2 is provided on the furnace body 1, a heat recovery mechanism is installed on the air outlet pipe 2, the heat recovery mechanism comprises a recovery cylinder 3, the recovery cylinder 3 comprises an inner cylinder 301 and an outer cylinder 302, a smoke exhaust chamber 4 is formed between the inner cylinder 301 and the outer cylinder 302, an exhaust pipe 5 is provided on the top of the smoke exhaust chamber 4, the exhaust pipe 5 is connected with the furnace body 1, so that the smoke exhausted from the smoke exhaust chamber can be recycled, and the waste of energy can be effectively avoided; a heat exchange tube 6 is installed in the inner cylinder 301, a spray assembly 7 is provided on the heat exchange tube 6, the spray assembly 7 comprises a spray pipe 701, a spray head 702 is installed on the spray pipe 701, and a plurality of nozzles are provided on the spray head 702, so that the heat inside the furnace body can be dissipated, and the water in the water pipe can be heated for other purposes, thereby achieving the effect of saving energy.

[0022] As a preferred embodiment of the utility model, it may also have the following additional technical features: a circulating water mechanism is provided between the inner cylinder 301 and the heat exchange tube 6, the circulating water mechanism includes a water outlet pipe 10 provided on the inner cylinder 301, a water inlet pipe 11 provided in the heat exchange tube 6, a circulating water pump 12 is installed between the water outlet pipe 10 and the water inlet pipe 11, and the water inlet pipe 11 and the water outlet pipe 10 are both installed at the bottom of the recovery cylinder 3. Thus, water can be recycled and the heat on the inner cylinder wall can be fully absorbed.

[0023] In this embodiment, a liquid pump 9 is installed on the other end of the water inlet pipe 11, and the liquid pump 9 is located outside the recovery cylinder. Thus, the heat inside the furnace body can be dissipated, and the water in the water pipe can be heated for other purposes, thereby achieving the effect of saving energy.

[0024] In this embodiment, there are ten spray pipes 701, and the ten spray pipes 701 are symmetrically arranged in pairs to form a group, so that the spray pipes 701 can fully absorb the heat on the wall of the inner cylinder.

[0025] In this embodiment, the smoke exhaust cavity 4 is connected with the outlet pipe 2; and the exhaust pipe 5 and the outlet pipe 2 are equipped with a filter, the filter includes a filter screen 13, and the filter screen 13 is filled with a desiccant; at the same time, a heating pipe 14 is provided at the bottom of the furnace body 1, and a plurality of air outlets 15 are provided on the heating pipe 14, and the exhaust pipe 5 is connected with the heating pipe 14.
