Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery technology, and specifically to a non-stop carbon replacement device. Background Technology
[0002] In the coating process of commercial power batteries, VOC gases are usually present, which are generally purified using activated carbon adsorption equipment.
[0003] Existing activated carbon adsorption equipment involves frequent carbon replacement, requiring multiple maintenance drawers and numerous seals. During use, frequent opening and closing of the doors can cause the seals to fail, eventually leading to leaks. Since activated carbon has a limited adsorption capacity, alarms usually sound during equipment operation, prompting the need to replace the carbon. This necessitates shutting down the entire line, resulting in significant cost losses. Utility Model Content
[0004] To address the technical problems in the existing technology, this utility model provides a non-stop carbon replacement device, including a high-speed pipe installed inside a housing. The inlet end of the high-speed pipe is connected to the air inlet of the housing, and the outlet end of the high-speed pipe extends into the housing from the air inlet after circling the housing. The high-speed pipe has several through holes, all of which are located inside the housing. The inlet end of the high-speed pipe is provided with a regulating valve for adjusting the flow rate entering the high-speed pipe.
[0005] Furthermore, several of the through holes are located in the middle of the housing.
[0006] Furthermore, the through holes are divided into upper and lower groups, and are located on the side closer to the inlet end and the outlet end, respectively.
[0007] Furthermore, the inlet end of the high-speed pipe is provided with a flared opening, and the small end of the flared opening is connected to the inlet end of the high-speed pipe, while the large end of the flared opening is connected to the air inlet.
[0008] Furthermore, the axis of the horn-shaped opening is arranged parallel to the axis of the air inlet.
[0009] Furthermore, the orifice area of the through hole is half the cross-sectional area of the high-speed pipe.
[0010] Beneficial effects:
[0011] 1. In this utility model, the high-speed pipe, several through holes, adjusting air valve, and the installation position of the high-speed pipe can control the pressure difference between the flow velocity inside the high-speed pipe and the flow velocity inside the box. On the one hand, it can create a negative pressure inside the box, so that carbon replacement or maintenance can be performed without stopping the machine. At the same time, it can also handle VOC gas and prevent VOC gas from entering the air. On the other hand, it can also ensure that the air volume passes through the box normally, ensuring the normal operation of the box. Specifically, when replacing carbon or performing maintenance, the air volume flow rate inside the high-speed pipe is increased by adjusting the air valve to create a negative pressure inside the box. During normal operation, the air volume flow rate inside the high-speed pipe is decreased by adjusting the air valve to make the pressure inside the box equal to or close to equal to the outside pressure.
[0012] 2. In this utility model, by setting the through holes in the middle of the box, the negative pressure inside the box can be maximized under the premise of the same airflow rate; combined with the arrangement of several through holes divided into upper and lower groups, the negative pressure balance inside the box can be optimized.
[0013] 3. In this utility model, the flared opening increases the air intake area at the inlet end, ensuring sufficient airflow velocity; combined with the fact that the axis of the flared opening is parallel to the axis of the air inlet, sufficient airflow velocity can be further ensured.
[0014] 4. In this utility model, by setting the orifice area of the through hole to be half the cross-sectional area of the high-speed pipe, the flow velocity and pressure drop can be optimally balanced, thereby generating the maximum negative pressure. Attached Figure Description

[0026] This utility model provides a non-stop carbon replacement device, such as... Figure 1 and Figure 2 As shown, the device includes a high-speed pipe 2 installed inside a housing 1. The inlet end of the high-speed pipe 2 is connected to the air inlet 3 of the housing 1. The outlet end of the high-speed pipe 2 extends into the housing 1 from the air inlet 3 after circling the housing 1 once. That is, part of the airflow entering the housing 1 through the air inlet 3 will enter from the inlet end of the high-speed pipe 2, circle around it, and then re-enter the housing 1 from the outlet end. The high-speed pipe 2 has several through holes 4, all of which are located inside the housing 1. The inlet end of the high-speed pipe 2 is provided with a regulating valve 5 for adjusting the flow rate entering the high-speed pipe 2. The regulating valve 5 can be a sliding plate that closes the inlet end. The sliding plate can be opened or closed by lifting or screwing on. By controlling the position of the sliding plate, the airflow rate can be adjusted.
[0027] In this embodiment, by setting the high-speed pipe 2, several through holes 4, regulating air valve 5, and the installation position of the high-speed pipe 2, the pressure difference between the flow velocity in the high-speed pipe 2 and the flow velocity in the housing 1 can be controlled. On the one hand, a negative pressure can be formed in the housing 1, so that carbon replacement or maintenance can be carried out without stopping the machine. At the same time, VOC gas can be treated to prevent VOC gas from entering the air. On the other hand, the air volume can be allowed to pass through the housing 1 normally, ensuring the normal operation of the housing 1. Specifically, when replacing carbon or performing maintenance, the air volume flow rate in the high-speed pipe 2 is increased by regulating air valve 5 to form a negative pressure in the housing 1. During normal operation, the air volume flow rate in the high-speed pipe 2 is decreased by regulating air valve 5 to make the pressure in the housing 1 equal to or close to equal to the external pressure.
[0028] In this utility model, preferably, such as Figure 1 As shown, several through holes 4 are located in the middle of the housing 1. In another embodiment, the high-speed pipe 2 is movably installed inside the housing 1. Specifically, the position of the high-speed pipe 2 can be moved by rotation, pulling, etc., so that the position of several through holes 4 inside the housing 1 can be freely adjusted, thereby achieving local negative pressure adjustment. Several through holes 4 are divided into upper and lower groups, and are located on the side close to the inlet end and the outlet end, respectively.
[0029] In this embodiment, by setting the through hole 4 in the middle of the box 1, the negative pressure inside the box 1 can be maximized under the premise of the same airflow rate; combined with the arrangement of several through holes 4 divided into upper and lower groups, the negative pressure balance inside the box 1 can be optimized.
[0030] In this utility model, preferably, such as Figure 1 As shown, the inlet end of the high-speed pipe 2 is provided with a flared mouth 6, and the small end of the flared mouth 6 is connected to the inlet end of the high-speed pipe 2, and the large end of the flared mouth 6 is connected to the air inlet 3; the axis of the flared mouth 6 is arranged parallel to the axis of the air inlet 3.
[0031] In this embodiment, the arrangement of the horn-shaped opening 6 increases the air intake area at the inlet end, ensuring sufficient airflow velocity. Furthermore, the parallel arrangement of the axis of the horn-shaped opening 6 with the axis of the air inlet 3 further ensures sufficient airflow velocity.
[0032] In this utility model, preferably, such as Figure 1 As shown, the orifice area of the through hole 4 is half the cross-sectional area of the high-speed pipe 2.
[0033] In this embodiment, by setting the orifice area of the through hole 4 to be half the cross-sectional area of the high-speed pipe 2, the flow velocity and pressure drop can be optimally balanced, thereby generating the maximum negative pressure.
[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0035] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
