Description

Technical Field

[0001] The present invention relates to the field of air purification, and particularly to a multi-stage air purification device for a dust-free workshop. Background Art

[0002] Under the condition that other conditions remain unchanged, when the wind speed is smaller, the purification of the filter is relatively better, because the slower the wind speed, the longer the residence time of the air flow in the filter, and the more stable and uniform the adsorption of the filter fibers in the filter. On the contrary, when the wind speed is too high, the dust-containing gas will quickly rush out of the filter during the process of hitting the filter fibers, greatly reducing the filtering effect. Therefore, in order to stabilize the filtering effect, multiple layers of filter fibers are set to intercept the dust-containing gas, which can reduce the escape phenomenon of the dust-containing gas under high wind speed conditions. In actual use, air purification equipment mostly operates at medium and low gears, that is, the filtering demand is the largest at medium and low wind speeds. Then, the use of multiple layers of filter fibers can significantly improve the filtering effect, but due to the low wind speed, it is significantly more difficult for the dust-containing gas to break through multiple layers of filter fibers, resulting in a problem of mismatch between the intake air volume and the exhaled air volume. Therefore, from the actual application, it is particularly important to propose an air purification device in which the wind speed corresponds to the number of filter fiber layers. Summary of the Invention

[0003] The purpose of the present invention is to provide a multi-stage air purification device for a dust-free workshop to solve the above technical problems.

[0005] A multi-stage air purification device for a dust-free workshop, including a frame body, which is divided into a third frame body, a second frame body, and a first frame body from the inside to the outside. Among them, the tops of the third frame body, the second frame body, and the first frame body are combined together, and a channel for gas discharge is formed at the combination;

[0006] A fan, which is placed in the first frame body and introduces the discharge port into the second frame body;

[0008] A partition, which is placed in each partition groove and is rotatably connected to each partition groove. Among them, the rotation path of the partition is located within the sliding path of the baffle, and is used to sequentially push the corresponding partition into the partition groove when the baffle slides upward along the height direction of the air duct body;

Among them, the pushing part always touches the filter cloth, and the pushing part is connected to the partition by a rope. When the baffle pushes the partition into the partition groove, the filter cloth is pushed by the pushing part and the filter cloth contacts the side wall of the third frame body.

[0011] Preferably, the baffle faces the air outlet of the fan. When the airflow pushes the baffle to slide upward in the air duct body, the air holes are gradually exposed, and the airflow pushing the baffle is discharged from the exposed air holes.

[0020] The beneficial effects of the present invention are:

Detailed implementation manners

[0032] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific embodiments and the accompanying drawings. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0033] The following describes the specific embodiments of the present invention with reference to the accompanying drawings.

[0034] Embodiment 1

[0035] In this embodiment, a multi-stage air purification device for a dust-free workshop is proposed. Please refer to Figure 3 . This multi-stage air purification device for a dust-free workshop has a frame body. Specifically, the frame body is successively the third frame body 6, the second frame body 10, and the first frame body 2 from the inside out. Please pay special attention to Figure 4 and Figure 6 . The tops of the third frame body 6, the second frame body 10, and the first frame body 2 are combined together, and a channel for gas discharge is formed at the combination. Of course, the frame body is integrated with a corresponding backboard. Please refer to Figure 2 . The upper backboard 4 covers the second frame body 10 and also covers the third frame body 6. In addition, a lower backboard 5 is provided below the upper backboard 4. Accordingly, the combination of the upper backboard 4 and the lower backboard 5 covers the first frame body 2.

[0036] Please refer to Figure 1-8 . Corresponding components are provided in the third frame body 6, the second frame body 10, and the first frame body 2;

[0037] A fan 11 is provided in the first frame body 2, and the exhaust port of the fan 11 is introduced into the second frame body 10;

[0038] A wind tunnel 9 is provided in the second frame body 10. For the wind tunnel 9, please pay special attention to Figure 7 . It includes a wind tunnel body 93 having air holes 92 and a partition groove 91. Among them, the wind tunnel body 93 is placed in the second frame body 10 and is docked with the exhaust port of the fan 11. In addition, there is a baffle 14 sliding along the height direction of the wind tunnel body 93 in the wind tunnel body 93, and the partition grooves 91 are arrayed in the height direction on both sides of the wind tunnel body 93. It should be noted that the partition groove 91 is a transfer groove for the partition 13, that is, each partition 13 corresponds to each partition groove 91, and each partition 13 is rotatably connected to its corresponding partition groove 91. It should be emphasized that the rotation path of the partition 13 is located within the sliding path of the baffle 14, that is, the sliding of the baffle 14 will affect the relative position of the partition 13 to the partition groove 91. As Figure 5 shown, the partition 13 at the lower position is pushed by the baffle 14 and rotates into the partition groove 91, while the partition 13 at the upper position, without being pushed by the baffle 14, rotates into the wind tunnel body 93 and has a relative angle with the partition groove 91;

[0039] A filter cloth 8 is provided in the third frame body 6. Please refer to Figure 4-6, 8. The filter cloth 8 extends from the midline in the length direction of the third frame body 6 to the height direction of the third frame body 6, and both ends of the filter cloth 8 are fixed to the upper and lower ends of the third frame body 6, thereby dividing the third frame body 6 into two independent chambers. Pushing parts 7 are arranged in both independent chambers. The pushing parts 7 are arranged in a staggered array in the two independent chambers from the height direction of the third frame body 6, and each pushing part 7 always touches the filter cloth 8. In addition, the pushing parts 7 are also connected to the partition plates 13 through ropes 12.

[0040] Regarding the pushing parts 7, it should be noted that one pushing part 7 corresponds to one partition plate 13 through a rope 12. Specifically, the pushing part 7 includes a sleeve 72 horizontally installed on one side wall of the third frame body 6 and a push rod 71 sliding in the sleeve 72. Among them, a spring 73 is embedded at the bottom of the sleeve 72. The end of the push rod 71 always touches one end of the spring 73. When the rope 12 passes through the sleeve 72 and is connected to one end of the spring 73 that touches the push rod 71, the push rod 71 and the partition plate 13 are combined. Further explanation, a support frame is installed at the end of the push rod 71 away from the spring 73, and the length of the support frame corresponds to the width of the filter cloth 8.

[0041] Please refer to Figure 1-9 , in the dust-free workshop multi-stage air purification equipment proposed in this embodiment, it lies in adjusting the specific shape of the filter cloth 8 in the third frame body 6 according to the air flow size, such as Figure 5 shown, the partition plate 13 at the lower position rotates into the partition plate groove 91 after being pushed by the baffle 14. Due to the rotation of the partition plate 13, the corresponding rope 12 enables the corresponding spring 73 to release its elastic force, and pushes the push rod 71 outwards relative to the sleeve 72, and pushes the filter cloth 8 to the side wall of the third frame body 6 through the support frame;

[0042] Please refer to Figure 5 , at the position opposite to the lower partition plate 13 is another partition plate 13, and this partition plate 13 controls another pushing part 7. Accordingly, after the baffle 14 pushes the two opposite partition plates 13, there will inevitably be two staggered pushing parts 7 that jointly push the filter cloth 8, thereby forming multiple filter chambers as shown in Figure 9 .

[0043] Further explanation, as shown in Figure 5 , the partition plate 13 at the upper position, because it is not pushed by the baffle 14, the pushing part 7 corresponding to this baffle 14 does not push the filter cloth 8 to the inner wall of the third frame body 6 to form more filter chambers.

[0044] In the foregoing, the movement of the partition plate 13 is controlled by the baffle 14, and the sliding of the baffle 14 depends on the air flow size. Specifically, please refer to Figure 5 and Figure 6, the baffle 14 is directly opposite to the exhaust port of the fan 11. Accordingly, when the airflow pushes the baffle 14 to slide upward in the air cylinder body 93, the air holes 92 are gradually exposed, and the airflow of the push baffle 14 is discharged from the exposed air holes 92. It can be seen that more airflow must flow through the air cylinder body 93 with a constant unit space, and more air holes 92 must be exposed. The air holes 92 are arranged in the height direction of the air cylinder body 93. Therefore, in this embodiment, the number of air holes 92 participating in the exhaust of the airflow of the push baffle 14 is proportional to the size of the airflow introduced by the fan 11.

[0045] Corresponding to the above description about the pushing part 7 pushing the filter cloth 8, when the airflow force is low, the baffle 14 can only push the partition 13 at the low position, while the partition 13 at the high position has no corresponding action to form more filter cavities because the airflow pushing force is not enough to push the baffle 14 to a higher position. On the contrary, when the airflow force is sufficient to make the low and high partitions 13 deflect into the partition groove 91, the pushing parts 7 corresponding to the low and high positions can push the filter cloth 8 to contact the inner wall of the third frame 6 to form more filter cavities.

[0046] In this embodiment, there are corresponding details that need to be further explained:

[0047] ①Please refer to Figure 5 and Figure 7 A limit frame 15 is provided in the fan 11, and the limit frame 15 is located in the sliding path of the baffle 14, and is used to limit the baffle 14 from entering the fan 11;

[0048] ②Please refer to Figure 1-3 , external air inlets 1 are provided on both sides of the first frame 2;

[0049] ③Please refer to Figure 1-5 , a secondary purification component 3 is installed in the channel provided at the joint, and the secondary purification component 3 may be one of a plasma purifier, an electrostatic purifier, and an activated carbon purifier;

[0050] ④Please refer to Figure 8 An inner air inlet 16 is provided at the bottom of the third frame body 6 for guiding the air flow guided from the air hole 92 into the third frame body 6 .
