[0028] like Figures 1-4 As shown, an embodiment of this utility model provides a casting molten iron composition analyzer, including an analyzer body 1, which is a furnace front carbon-silicon analyzer used to detect the composition of molten iron for casting. An air inlet 4 and an air outlet 3 are respectively opened on opposite sides of the analyzer body 1. A blower 2 is fixed on the inner wall of the analyzer body 1 corresponding to the air outlet 3. The analyzer also includes:
[0029] The heat exchange assembly 7 is fixed at the side of the detector body 1 corresponding to the air outlet 3 and has an air outlet cover 5, and the detector body 1 is fixed at the side corresponding to the air inlet 4 and has an air inlet cover 6. The heat exchange assembly 7 comprises a heat exchange cover 8 fixed between the air inlet cover 6 and the air outlet cover 5. The heat exchange cover 8 is used for the communication between the air inlet cover 6 and the air outlet cover 5. When the hair dryer 2 is running, the airflow flows through the hair dryer 2, the air outlet 3, the air outlet cover 5, the heat exchange cover 8 and the air inlet cover 6 in sequence from the inside of the detector body 1, and then enters the detector body 1 from the air inlet 4, so as to prevent the airflow from contacting the external environment and thus prevent dust from entering the inside of the detector body 1 and affecting the heat dissipation of the inside of the detector body 1. The top and bottom of the heat exchange cover 8 are respectively fixed with a water outlet box 10 and a water inlet box 9. The top of the heat exchange cover 8 is provided with two water channels 11. The water channels 11 are used for the communication between the water outlet box 10 and the water inlet box 9. The water inlet of the water inlet box 9 is communicated with a water pipe. The water pump is used to deliver water to the water inlet box 9 through the water pipe. Then the water in the water inlet box 9 flows into the water channels 11 and then flows into the water outlet box 10, and then is discharged from the water outlet of the water outlet box 10 to a collecting container. When the airflow flows through the heat exchange cover 8, the water flows through the water channels 11. The heat exchange cover 8 is used to realize the heat exchange between the airflow and the water flow, so as to reduce the temperature of the airflow entering the detector body 1 and thus improve the heat dissipation capacity of the detector body 1. Meanwhile, the rotating speed of the water pump can be changed to change the flow rate of the water flow in the water channels 11, so as to further improve the heat exchange capacity of the airflow and the water flow and thus further improve the heat dissipation capacity of the detector body 1.
[0030] As shown in Figure 2 In this embodiment, the inside of the heat exchange cover 8 is provided with an inner heat exchange sleeve one 12 and an inner heat exchange sleeve two 15. The top of the inner heat exchange sleeve one 12 and the inner heat exchange sleeve two 15 is fixedly connected with the top of the inner wall of the heat exchange cover 8. The bottom of the inner heat exchange sleeve one 12 and the inner heat exchange sleeve two 15 is fixedly connected with the bottom of the inner wall of the heat exchange cover 8. The two ends of the inner heat exchange sleeve one 12 are respectively communicated with the water outlet box 10 and the water inlet box 9. The two ends of the inner heat exchange sleeve two 15 are respectively communicated with the water outlet box 10 and the water inlet box 9. When the airflow flows through the heat exchange cover 8, it passes through the positions of the inner heat exchange sleeve one 12 and the inner heat exchange sleeve two 15. The inner heat exchange sleeve one 12 and the inner heat exchange sleeve two 15 are both filled with water. The inner heat exchange sleeve one 12 and the inner heat exchange sleeve two 15 are used to make the airflow exchange heat with the water again, so as to further reduce the temperature of the airflow entering the detector body 1 and thus further improve the heat dissipation capacity of the detector body 1.
[0031] As shown in Figure 2 In this embodiment, the inner heat exchange sleeve one 12 and the inner heat exchange sleeve two 15 are both in an elliptical shape. The resistance of the airflow flowing through the inner heat exchange sleeve one 12 and the inner heat exchange sleeve two 15 is reduced, so that the airflow flows more smoothly in the heat exchange cover 8.
[0032] As shown in Figure 2As shown in the figure, in this embodiment, the inner diameter of the inner heat exchange sleeve one 12 is smaller than the inner diameter of the inner heat exchange sleeve two 15, and the outer diameter of the inner heat exchange sleeve one 12 is smaller than the outer diameter of the inner heat exchange sleeve two 15. The gas flow first flows through the smaller inner heat exchange sleeve one 12, and then through the larger inner heat exchange sleeve two 15. This changes the flow path of the gas flow in the heat exchange cover 8, causing the gas flow to form a turbulent flow in the heat exchange cover 8. In the turbulent state, the gas flow continuously collides with the inner wall of the heat exchange cover 8 and the surfaces of the inner heat exchange sleeve one 12 and the inner heat exchange sleeve two 15, and mixes in the heat exchange cover 8. This makes the cooling of the gas flow more uniform, and the cooling degree of the parts in the detector body 1 is relatively consistent, preventing local temperature from being too high or too low, thereby effectively improving the uniformity of the cooling in the detector body 1.
[0033] As shown in the figure, Figure 2 In this embodiment, the surfaces of the inner heat exchange sleeve one 12 and the inner heat exchange sleeve two 15 are fixedly sleeved with a plurality of heat dissipation rings 14. The heat dissipation rings 14 increase the contact area between the gas flow and the inner heat exchange sleeve one 12 and the inner heat exchange sleeve two 15, thereby improving the heat exchange capacity of the water flowing in the inner heat exchange sleeve one 12 and the inner heat exchange sleeve two 15, and reducing the temperature of the gas flow entering the detector body 1, thereby improving the heat dissipation capacity of the detector body 1.
[0034] As shown in the figure, Figure 2 In this embodiment, the inner wall of the heat exchange cover 8 is fixed with a group of heat dissipation fins 13 on the opposite sides. The inner heat exchange sleeve one 12 and the inner heat exchange sleeve two 15 are located between the two groups of heat dissipation fins 13. Each group of heat dissipation fins 13 has a plurality of heat dissipation fins 13. The heat dissipation fins 13 are located at the position corresponding to the water channel 11 on the inner wall of the heat exchange cover 8. The heat dissipation fins 13 increase the contact area between the gas flow and the inner wall of the heat exchange cover 8, thereby improving the heat exchange capacity between the gas flow and the water flow, and reducing the temperature of the gas flow entering the detector body 1, thereby further improving the heat dissipation capacity of the detector body 1.
[0035] As shown in the figure, Figure 2 In this embodiment, the heat dissipation fins 13 are in a wave shape. The wave shape increases the contact area between the gas flow and the heat dissipation fins 13, thereby further improving the heat exchange capacity between the gas flow and the water flow at the heat dissipation fins 13.
[0036] Working principle: the blower 2 is operated, air current is entered into the air outlet cover 5 from the air outlet 3 of the detector body 1, then the air current is sequentially flowed through the heat exchange cover 8 and the air inlet cover 6 and then is entered into the detector body 1 from the air inlet 4, the circulation of the air current is realized, the air current is not contacted with the outside environment, the dust in the outside environment cannot enter into the inside of the detector body 1, so that the dust entering into the inside of the detector body 1 to influence the heat dissipation of the detector body 1 is prevented, the air current is flowed from the heat exchange cover 8, the water is entered into the water inlet box 9 from the water inlet of the water inlet box 9, then the water in the water inlet box 9 is flowed through the water channel 11 in the heat exchange cover 8 and the inner heat exchange sleeve one 12 and the inner heat exchange sleeve two 15 and flows to the water outlet box 10, and is discharged from the water outlet of the water outlet box 10, the air current is exchanged heat with the water when the air current is flowed from the heat exchange cover 8, so that the temperature of the air current entered into the inside of the detector body 1 is reduced, the heat dissipation capacity of the detector body 1 is improved;
[0037] Meanwhile, the air current is flowed from the heat exchange cover 8, the contact area of the air current and the inner heat exchange sleeve one 12 and the inner heat exchange sleeve two 15 is increased by the heat dissipation ring 14, the contact area of the air current and the inner wall of the heat exchange cover 8 is increased by the wave-shaped heat dissipation fin 13, so that the heat exchange capacity between the air current and the water is further improved, the temperature of the air current entered into the inside of the detector body 1 is further reduced, and the heat dissipation capacity of the detector body 1 is further improved.
[0038] The utility model covers any alternative, modification, equivalent method and scheme which are made on the essence and range of the utility model. In order to make the public have the thorough understanding of the utility model, the specific details are explained in the above preferred embodiment of the utility model, and the utility model can be completely understood without the description of these details for the person skilled in the art.
[0039] The above is only the preferred embodiment of the utility model, and it should be pointed out that, for ordinary skilled in the art, on the premise of not departing from the principle of the utility model, a plurality of improvements and refinements can be made, and these improvements and refinements should be regarded as the protection range of the utility model.
