DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3A reflective natural gas furnace for preparing an intermediate alloy comprises a furnace body 1, an exhaust pipe 2 is arranged on the furnace body 1, a hot water tank 3 and a cold water tank 5 are arranged around the furnace body 1, the hot water tank 3 is used to collect hot water, and the cold water tank 5 contains cold water for heating, a drain pipe is arranged on the hot water tank 3, and a manual valve is arranged on the drain pipe, wherein the furnace body 1 is a prior art product, and this scheme enriches the device structure without changing the furnace body 1, so the structure and working distance of the furnace body 1 are not described in detail here.

[0021] A heating box 6 is provided outside the exhaust pipe 2, a pump water box 4 is provided above the hot water tank 3 through a support rod 9, a pump water chamber 17 and a rotating chamber 18 are provided inside the pump water box 4, the heating box 6 is connected to the cold water tank 5 and the pump water chamber 17 through a suction pipe 7 and a connecting pipe 22 respectively, the pump water chamber 17 is connected to the hot water tank 3 through a water supply pipe 8, a double-axis motor is provided at the bottom of the pump water box 4, a fan blade 12 is provided on the hot water tank 3 through an extension plate 10, a driving gear 15 is provided on the extension plate 10, the driving gear 15 is connected to the double-axis motor through a rotating mechanism, the driving gear 15 is connected to the fan blade 12 through a transmission mechanism, a reciprocating screw 19 connected to the double-axis motor is rotatably provided in the rotating chamber 18, a piston plate 20 is provided in the pump water chamber 17, and the piston plate 20 is connected to the reciprocating screw 19 through a connecting mechanism.

[0022] The rotating mechanism includes a pulley 13 arranged on the output shaft of the dual-axis motor and on the driving gear 15. The two pulleys 13 are connected by a belt 14, and the power transmission of the dual-axis motor is achieved by means of the pulley 13 and the belt 14.

[0023] The transmission mechanism includes a transmission gear 16 arranged on the support plate 11 and connected to the fan blades 12. The driving gear 15 is meshed with the transmission gear 16. The power transmission of the dual-axis motor is realized by means of the above-mentioned driving gear 15 and the transmission gear 16. The speed of the dual-axis motor in this scheme is not fast, ensuring that the cold water has a sufficient residence time in the heating box 6. At the same time, the transmission gear 16 is smaller than the driving gear 15, thereby ensuring the speed of the fan blades 12.

[0024] The connecting mechanism includes a connecting frame 21 threadedly sleeved on the outer wall of the reciprocating screw 19. The connecting frame 21 is U-shaped and both ends are connected to the piston plate 20. Both ends slide through the inner wall of the rotating chamber 18 and extend into the water pump chamber 17. Therefore, it has its own limit and will not rotate with the reciprocating screw 19.

[0025] A first valve is provided in the water supply pipe 8, and a second valve is provided in the connecting pipe 22. Both the first valve and the second valve are one-way valves, and the first and second valves realize one-way flow of water.

[0026] The exhaust pipe 2 is externally sheathed with an insulation sleeve, which is arranged on a section where the exhaust pipe 2 is connected to the furnace body 1 and the heating box 6 to prevent heat loss. The portion of the exhaust pipe 2 in the heating box 6 is designed in a spiral shape to ensure that the high-temperature flue gas stays in the heating box 6 for a sufficient time to avoid excessive flow rate affecting the heat exchange with cold water.

[0027] When the utility model is used, the furnace body 1 generates high-temperature flue gas when working, and the above-mentioned high-temperature flue gas is discharged through the exhaust pipe 2. At the same time, the double-axis motor in this scheme is in a starting state, and the two output shafts of the double-axis motor are rotating, so the pulley 13 and the reciprocating screw 19 connected thereto are in a rotating state. The pulley 13 can drive the driving gear 15 to rotate with the help of another pulley 13 and the belt 14, and the driving gear 15 drives the transmission gear 16 meshing therewith to drive the fan blade 12 to rotate.

[0028] At the same time, when the reciprocating screw 19 rotates, the connecting frame 21 on its outer wall will reciprocate up and down in the rotating chamber 18, thereby driving the piston plate 20 to reciprocate up and down in the water pumping chamber 17. When the piston plate 20 moves downward, the heating box 6 is in a negative pressure state, and the cold water in the cold water tank 5 will be sucked into the heating box 6 through the water suction pipe 7. It will absorb the heat of the high-temperature flue gas in the exhaust pipe 2 to heat itself, and then enter the water pumping chamber 17 through the connecting pipe 22. During the rising process of the piston plate 20, the heated water can be sent to the hot water tank 3 through the water supply pipe 8 for collection.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
