[0022] The embodiment of the present application provides a lime production pressure furnace device. Due to the use of a high-temperature and high-pressure heat recovery pipe and a release valve, a large amount of released waste heat can enter the silo to heat the raw materials, and the excess heat energy is converted into electrical energy through a heat exchanger, so that the waste heat can be fully utilized. The lime can be quickly taken out through the cooperation of the silo and the supporting seat, thereby improving work efficiency. Therefore, the technical problems of poor waste heat utilization effect of the existing pressure furnace during use and poor quality of the lime produced are effectively solved, thereby achieving effective utilization of waste heat and improving the quality of lime.

[0023] Example 1

[0024] The technical solution in the embodiment of the present application is to effectively solve the technical problems that the waste heat utilization effect of the existing pressure furnace is poor and the quality of the produced lime is poor when in use. The overall idea is as follows:

[0025] In view of the problems existing in the prior art, the utility model provides a lime production pressure furnace device, which comprises: a furnace body 5; a furnace door 12, which is movably embedded in the inner wall of the furnace body 5, a threaded shaft 7 is fixedly installed on one side of the furnace door 12, one end of the threaded shaft 7 is fixedly connected to a motor 11, and the other end of the threaded shaft 7 is fixedly connected to a silo 8; wherein the inner wall of the furnace body 5 is slidably connected to a guide rod 18, one side of the guide rod 18 is fixedly connected to a bearing seat 9, the bearing seat 9 is located between the silo 8 and the furnace body 5, and the threaded shaft 7 is fixedly connected to the inner wall of the furnace body 5. The outer wall of the threaded shaft 7 is threadedly connected to the inner wall of the bearing seat 9, and a rubber pad is provided on one side of the furnace door 12. When the furnace door 12 is embedded in the inner wall of the furnace body 5, that is, the pressure furnace is in a closed state, it is ensured that the interior of the furnace body 5 is in a closed state. When the internal work is completed, through the spiral activity of the screw 13 and the base 16, the furnace door 12, the bearing seat 9 and the silo 8 connected by the threaded shaft 7 are translated outward under the action of the guide rod 18. When the silo 8 is completely pulled out of the furnace body 5, the motor 11 is connected to the external power supply to rotate the silo 8, and then the lime inside is poured out.

[0026] In some examples, the outer surface of the furnace body 5 is fixedly sleeved with two fixing plates 4, the bottom of the two fixing plates 4 is fixedly installed with a base 16, one end of the base 16 is movably embedded with a screw 13, one end of the screw 13 is fixedly connected to a turntable 14, and the other end of the screw 13 is fixedly connected to a connecting rod 10, and the connecting rod 10 is fixedly arranged on the outer surface of the furnace door 12, such as Figure 1 As shown, the silo 8, the bearing base 9 and the furnace door 12 can be moved horizontally.

[0027] In some examples, a hopper 2 is fixedly installed on the top of the furnace body 5, and high-temperature and high-pressure heat recovery pipes 3 are fixedly connected to both sides of the hopper 2 close to the fixed plate 4. The outer surface of the high-temperature and high-pressure heat recovery pipe 3 is provided with a high-temperature and high-pressure heat release valve 17, such as Figure 2As shown, when the furnace body 5 finishes working, the high-temperature and high-pressure heat energy release valve 17 is opened, so that a large amount of heat energy generated inside the furnace body 5 enters the interior of the hopper 2 through the high-temperature and high-pressure heat energy recovery pipe 3, and the raw materials inside the hopper 2 are preheated. A pressure gauge 20 is fixedly installed on the outer surface of the hopper 2, and a heat energy conduit 21 is fixedly connected to the side of the hopper 2 close to the pressure gauge 20. A heat energy release valve 25 is fixedly arranged on the outer surface of the heat energy conduit 21, and one end of the heat energy conduit 21 is fixedly connected to a heat exchanger 22, and the lower surface of the heat exchanger 22 is fixedly connected to an electric wire 19. A battery 15 is fixedly installed at one end of the wire 19, and the battery 15 is fixedly arranged on the upper surface of the base 16. When the heat energy release valve 25 and the high-temperature and high-pressure heat energy release valve 17 are in an open state, the hopper 2, the high-temperature and high-pressure heat energy recovery pipe 3, the furnace body 5 and the heat energy conduit 21 can be interconnected, and the pressure inside the hopper 2 is detected by the pressure gauge 20. When the pressure inside the hopper 2 is too high, the heat energy release valve 25 is opened, and the heat energy is converted into electrical energy through the heat energy conduit 21 and the heat exchanger 22, and then flows into the battery 15, so that a large amount of electrical energy can be collected for use by the power supply.

[0028] In the specific implementation process, before use, ensure that the high-temperature and high-pressure heat release valve 17, the unloading valve 6 and the heat release valve 25 are in a closed state. After the hopper 2 is filled with raw materials, the cover 1 is sealed to make the inside of the hopper 2 in a closed state. When the furnace body 5 is finished working, open the high-temperature and high-pressure heat release valve 17 to allow the residual heat to enter the hopper 2 through the high-temperature and high-pressure heat recovery pipe 3 to recover the residual heat of the raw materials. If the pressure displayed on the pressure gauge 20 is greater than what the hopper 2 can withstand, open the heat release valve 25 to convert the residual heat from thermal energy into electrical energy through the heat energy conduit 21 and the heat exchanger 22, and collect it in the storage battery 15. When the internal pressure and temperature of the furnace body 5 drop to a suitable level, rotate the turntable 14. Under the spiral motion of the screw 13 and the base 16, the furnace door 12, the supporting seat 9 and the silo 8 are translated outward through the connecting rod 10. Then start the motor 11 to rotate the silo 8 to pour out the lime. After the work is completed, move the furnace door 12, the supporting seat 9 and the silo 8 into the furnace body 5 and close the furnace door 12. At this time, open the discharge valve 6 and pour the raw materials into the silo 8. When the silo 8 is filled with raw materials, the high-temperature and high-pressure thermal energy release valve 17, the discharge valve 6 and the thermal energy release valve 25 must be closed, and finally the furnace body 5 is put into operation.

[0030] Based on Example 1, the present application example is a feasible technical solution for a lime production pressure furnace device, and the overall idea is as follows:

[0031] A cover 1 is movably installed on the top of the hopper 2, and a discharge valve 6 is fixedly installed on one side of the raised part of the hopper 2. When the raw materials are poured into the hopper 2, the cover 1 is covered to make the hopper 2 in a closed state, and then the waste heat generated by the pressure furnace is used to preheat the raw materials so that the raw materials can be more fully utilized. After the preheating is completed, the discharge valve 6 can be opened to allow the raw materials to fall into the silo 8, so that the raw materials are isolated from the external environment to avoid poor preheating effect.

[0033] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
