Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and specifically to a make-up air structure for a sheet metal purification system. Background Technology

[0002] During the purification process of the boards, they need to be heated to remove harmful substances such as formaldehyde.

[0003] like Figure 1 As shown, the existing board purification equipment, as described in Chinese patent application CN114442696B, has a heating oil pipe 4 for placing the board 15 below the bottom of the insulation box 1. An air outlet 3 is provided below the heating oil pipe 4. The air outlet 3 is connected to an air inlet 2 located at the top of the insulation box 1. A circulating fan 7 is provided between the air inlet 2 and the air outlet 3, so that the air in the insulation box 1 circulates between the air inlet 2 and the air outlet 3, allowing the air in the entire insulation box 1 to circulate and form a heat circulation, which can ensure a uniform temperature distribution inside the box.

[0004] However, since harmful substances are released during the purification process of the boards, using only this heat circulation structure will cause harmful substances to accumulate in the insulation box. If only an exhaust system is added to the insulation box, the air pressure inside the insulation box will drop, affecting the quality of the boards. Utility Model Content

[0005] The purpose of this invention is to provide a replenishment air structure for a board purification system, which can replenish fresh air to the board purification system with a heat circulation structure to maintain the air quality and air pressure balance inside the insulation box.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0007] A makeup air structure for a board purification system includes an insulated box with an air inlet and an air outlet connected end-to-end. A heating oil pipe is located at the bottom of the insulated box, with the air outlet below the heating oil pipe and the air inlet at the top. The heating oil pipe is connected to a thermal oil heater. An exhaust system is connected to the insulated box, and the air inlet and outlet are connected via an air supply pipe. A circulating fan is installed on the air supply pipe, which is also connected to a makeup air pipe. Its function is to remove harmful substances from the insulated box through the exhaust system and to replenish fresh air into the insulated box through the makeup air pipe, maintaining air pressure balance within the insulated box.

[0008] Furthermore, the connection point between the make-up air pipe and the air supply pipe is located between the circulating fan and the air outlet.

[0009] Furthermore, a partition is provided between the make-up air duct and the supply air duct. Its function is that, since the connection between the make-up air duct and the supply air duct is located between the circulating fan and the air outlet, the circulating fan will blow the circulating air into the make-up air duct, affecting the make-up air efficiency. By setting up the partition, the circulating air in the supply air duct can be prevented from entering the make-up air duct.

[0010] Furthermore, the connection point between the make-up air pipe and the air supply pipe is located between the circulating fan and the air inlet.

[0011] Furthermore, the make-up air duct is equipped with a make-up air fan. Its function is to improve the make-up air efficiency of the make-up air duct by installing the make-up air fan.

[0012] Furthermore, the make-up air duct is equipped with a make-up air valve, and the make-up air fan is located between the air supply duct and the make-up air valve. Its function is to control the opening and closing of the make-up air duct by means of the make-up air valve.

[0013] Furthermore, the makeup air valve is a proportional valve, and a makeup air flow meter is installed on the makeup air duct. Its function is to adjust the opening degree of the proportional valve based on the flow meter reading, thereby regulating the makeup air volume. The proportional valve can be controlled manually or electrically, depending on the makeup air flow meter reading. The method of electrically controlling the proportional valve utilizes existing technology and will not be elaborated upon.

[0014] Furthermore, the exhaust system includes an exhaust duct with an exhaust flow meter installed on it. Its function is to adjust the opening degree of the make-up air valve by combining the exhaust flow meter reading with the make-up air flow meter reading, thereby adjusting the air pressure inside the insulation box.

[0015] Furthermore, the exhaust system is located at the top inside the insulation box, on the side of the insulation box furthest from the air inlet. Its function is to prevent airflow short-circuiting between the exhaust system and the air inlet through the spatial design of the exhaust system.

[0016] Furthermore, the air supply duct is equipped with an activated carbon filter layer and a metal filter screen from the inside out. The function of these two elements is to improve the quality of the air entering the insulation box.

[0017] The beneficial effects of this utility model are:

[0018] 1. The exhaust system can remove harmful substances from the insulated box, while the air supply duct can replenish fresh air into the insulated box to maintain the air pressure balance inside the insulated box.

[0019] 2. By setting the make-up air flow meter and using a proportional valve design for the make-up air valve, the opening degree of the proportional valve can be adjusted according to the reading of the make-up air flow meter, thereby achieving the effect of regulating the make-up air volume.

[0027] Example 1

[0028] A makeup air structure for a board-based air purification system, such as Figure 2As shown, the device includes an insulated box 1, with an air inlet 2 and an air outlet 3 connected end-to-end. A heating oil pipe 4 is located at the bottom of the insulated box 1, with the air outlet 3 below the heating oil pipe 4 and the air inlet 2 above the insulated box 1. The heating oil pipe 4 is connected to a thermal oil heater 5. An exhaust system is connected to the insulated box 1, with the air inlet 2 and air outlet 3 connected by an air supply pipe 6. A circulating fan 7 is installed on the air supply pipe 6, and a makeup air pipe 8 is connected to the air supply pipe 6. Its function is to remove harmful substances from the insulated box 1 through the exhaust system, and to replenish fresh air into the insulated box 1 through the makeup air pipe 8, maintaining the air pressure balance inside the insulated box 1.

[0029] Specifically, such as Figure 2 As shown, the connection point between the make-up air pipe 8 and the air supply pipe 6 is located between the circulating fan 7 and the air outlet 3.

[0030] Specifically, such as Figure 2 As shown, a partition 9 is provided between the make-up air duct 8 and the air supply duct 6. The length of the partition 9 is less than the inner diameter of the air supply duct 6. Its function is that, since the connection between the make-up air duct 8 and the air supply duct 6 is located between the circulating fan 7 and the air outlet 3, the circulating fan 7 will blow circulating air into the make-up air duct 8, affecting the make-up air efficiency. By setting the partition 9, the circulating air in the air supply duct 6 can be prevented from entering the make-up air duct 8.

[0031] Specifically, such as Figure 2 As shown, a makeup air fan 10 is provided on the makeup air duct 8. Its function is to improve the makeup air efficiency of the makeup air duct 8 by setting up the makeup air fan 10.

[0032] Specifically, such as Figure 2 As shown, the make-up air duct 8 is equipped with a make-up air valve, and the make-up air fan 10 is located between the air supply duct 6 and the make-up air valve. Its function is to control the opening and closing of the make-up air duct 8 by setting the make-up air valve.

[0033] Specifically, such as Figure 2 As shown, the make-up air valve is a proportional valve, and a make-up air flow meter 11 is installed on the make-up air duct 8. Its function is to adjust the opening degree of the proportional valve based on the reading of the make-up air flow meter 11, thereby regulating the make-up air volume. The make-up air flow meter 11 can control the proportional valve manually or electrically. The method of electrically controlling the proportional valve uses existing technology and will not be elaborated upon.

[0034] Specifically, such as Figure 2As shown, the exhaust system includes an exhaust duct with an exhaust flow meter 12 installed on it. Its function is to adjust the opening degree of the make-up air valve by combining the reading of the make-up air flow meter 11 with the exhaust flow meter 12, thereby adjusting the air pressure inside the insulation box 1.

[0035] Specifically, such as Figure 2 As shown, the exhaust system is located above the insulated box 1, on the side of the insulated box 1 away from the air inlet 2. Its function is to avoid airflow short-circuiting between the exhaust system and the air inlet 2 through the spatial design of the exhaust system.

[0036] Specifically, such as Figure 2 As shown, the air supply duct 8 is provided with an activated carbon filter layer 13 and a metal filter screen 14 from the inside out. Their function is to improve the quality of the air entering the insulation box 1 by using the activated carbon filter layer 13 and the metal filter screen 14 on the air supply duct 8.

[0037] The working principle of this embodiment is explained as follows: The circulating fan 7 blows the circulating air through the air outlet 3 to the heating oil pipe 4. The heated gas is blown to the plate 15 in the heat preservation box 1, so that the plate 15 is heated and harmful gases are discharged. The gas after heating the plate 15 rises in the heat preservation box 1. Part of it is discharged through the exhaust pipe, and the other part enters the air supply pipe 6 through the air inlet 2 for circulation. The circulating air continues to be blown to the air outlet 3 by the circulating fan 7. The makeup air fan 10 draws fresh air into the makeup air pipe 8 and blows it to the air outlet 3.

[0038] Example 2

[0039] Specifically, such as Figure 3 As shown, the connection point between the make-up air pipe 8 and the air supply pipe 6 is located between the circulating fan 7 and the air inlet 2.

[0040] The working principle of this embodiment is explained as follows: Since the circulating fan 7 is located after the intersection of the air supply pipe 8 and the air delivery pipe 6 in the direction of the circulating air flow, it can deliver the circulating air in the air delivery pipe 6 and the fresh air in the air supply pipe 8 to the circulating fan 7 together. Therefore, there is no situation where the circulating air enters the air supply pipe 8, and there is no need to install the partition 9.

[0041] The remaining structure and principles are the same as in Embodiment 1. The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of this utility model and within the spirit and principles of this utility model shall still fall within the protection scope of this utility model's technical solution.
