Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 3 , the utility model provides a technical solution:

[0020] A device for recovering and utilizing waste heat from phosphate ammonium production comprises a production shell 1 and several support frames installed at the bottom of the production shell 1. A heating chamber 2 is provided in the middle of the production shell 1, and a hollow insulation chamber 3 is provided between the heating chamber 2 and the inner wall of the production shell 1. A sealing cover plate 4 is detachably installed on the top of the heating chamber 2, a refrigerator 5 is installed on the top of the sealing cover plate 4, a temperature sensor and several cold air nozzles are installed on the bottom, one side of the refrigerator 5 is connected to the cold air nozzle through a cold air pipe, a heater 6 is installed inside the heating chamber 2, and a control component is installed at the bottom of the outer side for controlling the opening of the refrigerator 5 and the heater 6, a support seat is installed on one side of the support frame, a water tank 7 is installed above the support seat, a water pump connected to the water tank 7 is installed on the top of the water tank 7, a water inlet pipe is connected to the output end of the water pump, the water inlet pipe is connected to the insulation chamber, and a drainage pipe is connected between the bottom of the water tank 7 and the insulation chamber 3.

[0021] During use, the production materials are placed in the heating chamber 2, and the production materials are heated by the heater 6. The temperature sensor is used to monitor the temperature inside the heating chamber 2 in real time. When the internal temperature exceeds the set value and needs to be cooled, the refrigerator 5 is started, and the cold air reaches the cold air nozzle through the cold air pipe and is sprayed into the heating chamber 2 for cooling. By setting up the insulation chamber 3, on the one hand, it plays a role of insulation during heating and reduces heat loss. On the other hand, during cooling, the water pump can be started to extract water from the water tank 7 and enter the insulation chamber 3 through the water inlet pipe, thereby absorbing heat and heating it into hot water for use by other equipment, thereby achieving the purpose of waste heat recovery. At the same time, the hot water in the insulation chamber 3 can also keep the internal materials warm, so that the internal temperature can be cooled at a uniform rate.

[0022] A handle is fixedly mounted on the top of the sealing cover plate 4 to facilitate installation and removal.

[0023] A solenoid valve is installed inside the drainage pipe. After the work is completed, the solenoid valve can be opened to allow the hot water to be discharged into the water tank 7 through the drainage pipe for use by other equipment.

[0024] A display panel 14 electrically connected to the temperature sensor is installed on the outer surface of the production shell 1. The temperature monitored by the temperature sensor will be displayed through the display panel 14 for the convenience of staff to watch.

[0025] The control assembly includes a control box 8 installed at the bottom of the production shell 1, a sealing tube 9 installed inside the control box 8, a piston rod 11 installed inside the sealing tube 9 with a sliding seal, and a movable plate 10 connected to the piston rod 11. A heat conducting plate is installed at the bottom end of the heating chamber, and an expansion liquid for driving the piston rod 11 to move is provided between the heat conducting plate and the piston rod 11. A first contact electrode 12 is symmetrically installed on the bottom wall of the control box 8, and a fixed seat and a second contact electrode 13 are symmetrically installed above.

Both ends of the movable plate 10 are slidably connected to the control box 8, and a third contact electrode 15 is symmetrically installed on both sides.

[0026] It should be noted that the expansion liquid here is a liquid that expands when heated and contracts when cooled. Kerosene can be used. Kerosene has the characteristics of expanding when heated and contracting when cooled, and the range of deformation is increased. When the internal temperature exceeds the set value, the heat will be transferred to the expansion liquid through the heat conduction plate, driving the piston rod 11 to move downward, so that the third contact electrode 15 and the first contact electrode 12 are in full contact, the refrigerator 14 is started, and the spring plays a role in protecting the electrodes. Similarly, when the temperature is low, the third contact electrode 15 and the second contact electrode 13 are in full contact, the heater 6 is started, and the production material is automatically heated and cooled, replacing manual adjustment and improving work efficiency.
