[0002] Currently, pig farms use water-cooled boilers with circulating water to provide underfloor heating to maintain ground temperature. While this keeps piglets warm and reduces diarrhea, it doesn't ensure adequate room temperature. Farmers currently use heat lamps to maintain room temperature, but these consume a lot of electricity, increasing farming costs, wasting energy, and making it difficult to maintain consistent temperatures. In some remote mountainous areas, electricity is insufficient, and prolonged use of electrical equipment poses a risk of electric shock. Utility Model Content

Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0017] The following is in conjunction with the appendix Figure 1-2 The present invention will be further described as follows:
[0018] A dual-purpose (water and air) heating furnace for pigsties includes a shell 1. A partition 2 is longitudinally arranged inside the shell 1, dividing the shell 1 into two independent and sealed water heating chambers 3 and air heating chambers 15. A heating device is installed in the water heating chamber 3. A chimney 11 is installed at the top of the heating device, penetrating the shell 1. A flue pipe 16 is installed at the bottom of the heating device. The flue pipe 16 is connected to the chimney 11 through a flue gas circulation device installed in the water heating chamber 3 and the air heating chamber 15. The water heating device and the air heating device, which are connected to the water heating chamber 3 and the air heating chamber 15, are respectively installed on the outside of the shell 1.
[0019] In this embodiment, the heating device generates heat by burning fuel, which heats the water-heating chamber 3. The flue gas produced by fuel combustion exits the housing 1 from the bottom of the heating device via a flue gas circulation device, which heats both the water-heating chamber 3 and the air-heating chamber 15. Water enters the water-heating chamber 3 from the water-heating device, is heated by the heating device and the flue gas circulation device, and is then discharged to provide water-based heating for the pigsty. Air enters the air-heating chamber 15 from the air-heating device, is heated by the flue gas circulation device, and is then discharged to provide air-based heating for the pigsty. This forms a dual-use heating system (water-heating and air-heating), which improves and maintains the temperature of the pigsty, reduces the farmers' breeding costs, and also reduces electrical safety hazards.
[0020] Preferably, when the flue gas recirculation device is not turned on, the flue gas generated by fuel combustion is discharged from the chimney 11.
[0021] The heating device includes a furnace body 4, inside which is a furnace chamber 5. From top to bottom, a coal feeding pipe 7, a slag cleaning pipe 8, and an ash cleaning pipe 9 are fixedly connected to the outside of the furnace body 4 and communicate with the furnace chamber 5. A grate 6 is installed inside the furnace chamber 5 between the slag cleaning pipe 8 and the ash cleaning pipe 9. An oxygen distribution pipe 10, which communicates with the furnace chamber 5, is fixedly installed on the outside of the furnace body 4 between the coal feeding pipe 7 and the slag cleaning pipe 8. A chimney 11, which communicates with the furnace chamber 5, is installed on the top of the furnace body 4. The coal feeding pipe 7, the slag cleaning pipe 8, the ash cleaning pipe 9, the oxygen distribution pipe 10, and the chimney 11 all penetrate the shell 1 and extend to its outside. A flue pipe 16, which communicates with the furnace chamber 5, is fixedly connected to the outside of the furnace body 4 below the grate 6.
[0022] In this embodiment, fuel is fed into the grate 6 inside the furnace 5 through the coal feeding pipe 7. The slag produced by fuel combustion is discharged through the slag removal pipe 8, and the ash falls through the grate 6 to the bottom of the furnace 5 and is then discharged through the ash removal pipe 9. The operation of the flue gas recirculation device creates a negative pressure inside the furnace 5, which allows air from outside the shell 1 to be drawn into the furnace 5 through the oxygen distribution pipe 10, thus supplementing oxygen for fuel combustion.
[0023] The flue gas circulation device includes a water heat exchanger 17 and an air heat exchanger 19. The water heat exchanger 17 is fixedly installed in the water heating chamber 3, and its lower end is connected to the flue gas outlet pipe 16. The air heat exchanger 19 is fixedly installed in the air heating chamber 15, and one end of the air heat exchanger 19 is connected to the upper end of the water heat exchanger 17 through a connecting pipe 18. A smoke induced fan 20 is fixedly installed on the outside of the shell 1. The other end of the air heat exchanger 19 is connected to the smoke inlet end of the smoke induced fan 20, and the smoke outlet end of the smoke induced fan 20 is connected to the chimney 11 through an auxiliary smoke pipe 21.
[0024] In this embodiment, under the action of the flue gas induced by ...
[0025] The water heating device includes an inlet pipe 12 and an outlet pipe 13. The inlet pipe 12 is fixedly installed on the lower side of the outer side of the housing 1, and the outlet pipe 13 is fixedly installed on the upper side of the outer side of the housing 1. A water replenishment tank 14 is fixedly installed on the top of the housing 1. The inlet pipe 12, the outlet pipe 13 and the water replenishment tank 14 are all connected to the water heating cavity 3.
[0026] In this embodiment, water enters the water heating chamber 3 through the inlet pipe 12 to absorb heat from the furnace body 4, the flue pipe 16, and the water heat exchanger 17. Hot water is discharged from the outlet pipe 13 to provide water heating for the pigsty. Preferably, the water replenishment tank 14 is used for water replenishment and venting. The water replenishment tank 14 is a further application of existing technology in this embodiment.
[0027] The air heating device includes a blower 22 fixedly installed outside the housing 1. The air outlet of the blower 22 is connected to the air heating cavity 15. The air heating cavity 15 is provided with a plurality of air-repellent plates 23 that cooperate with the air heat exchanger 19. An air outlet 24 connected to the air heating cavity 15 is opened on the side of the housing 1 away from the blower 22.
[0028] In this embodiment, the blower 22 draws outside air into the air-heating chamber 15. The air absorbs heat from the connecting pipe 18 and the air heat exchanger 19, forming hot air which is then discharged from the air outlet 24 for heating the pigsty. Preferably, a baffle plate 23 is provided to block the air blown into the air-heating chamber 15 by the blower 22, allowing it to more fully absorb heat from the connecting pipe 18 and the air heat exchanger 19, thus improving heat exchange efficiency.
[0029] The top of the water heat exchanger 17 and the bottom of the air heat exchanger 19 are all provided with a dust cleaning pipe 26 connected to them. The dust cleaning pipe 26 penetrates the shell 1 and is detachably provided with a dust cleaning cover 25 that is sealed to it.
[0030] In this embodiment, opening the dust removal cover 25 on the top of the water heat exchanger 17 and the air heat exchanger 19 can clean the dust adhering to the inner wall of the water heat exchanger 17 and the air heat exchanger 19. The cleaned dust is discharged from the dust removal pipe 9 and the dust removal pipe 26 at the bottom of the air heat exchanger 19, respectively.
[0031] The exterior of the housing 1 is provided with a thermal insulation layer 27.
[0032] In this embodiment, the insulation layer 27 can reduce the loss of heat in the water-heated cavity 3 and the air-heated cavity 15.
