Technical Field
[0001] This utility model relates to the technical field of windmill filter units, and more specifically, to a modular windmill filter unit. Background Technology
[0002] Traditional ceiling-mounted air conditioning systems consist of fans installed on the ceiling of a cleanroom or enclosed space, with terminal filter boxes installed at the outlet of each fan. Since a certain air pressure must be maintained in every part of the cleanroom, the traditional approach requires installing several fans in the required locations.
[0003] The existing utility model with announcement number CN2615556Y discloses a modular windmill filter unit. The unit mainly consists of a windmill module and wind boxes surrounding it, which are modularly combined into a box. The sides of these wind boxes are provided with air outlets. The windmill module forms a pressure chamber in the box, so that after the windmill draws in air from the top, the air can be discharged from the bottom of the box or from the side air outlets of each wind box. In this way, multiple terminal filter boxes can be supplied at the same time. Because it is combined in a modular manner, the windmill module is easier to disassemble and replace. In addition, any one of the wind boxes can be replaced with a dry disc type or chemical filter wind box to form a multifunctional and high-efficiency modular windmill filter unit.
[0004] However, the following drawbacks still exist: the wind turbine module and the wind box are assembled in a modular manner, and when the wind box needs to be adjusted and reassembled later, there is a lack of quick-disassembly components, making it impossible to quickly disassemble the wind box. Therefore, a modular wind turbine filter unit is proposed. Utility Model Content
[0005] The purpose of this utility model is to address the problem that in the current system where the wind turbine module and the wind box are assembled in a modular manner, there is a lack of quick-disassembly components when the wind box needs to be adjusted and reassembled later, making it impossible to quickly disassemble the wind box.
[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0007] The present invention is as follows: a modular windmill filter unit, including a fan and modular air boxes arranged on the four sides of the fan. The interior of the modular air box is provided with an air inlet and an air outlet corresponding to the side air outlet of the fan. One side of the air outlet of the modular air box can be connected to a terminal air box through an air duct.
[0008] A plug is fixedly installed on one side of the modular air box. A slot adapted to the plug is opened inside the fan. A first spring is fixedly installed inside the fan. A limit block is fixedly installed at one end of the first spring. A limit groove adapted to the limit block is opened inside the plug. A pull rod is fixedly installed on the inner side of the limit block.
[0009] As a preferred technical solution of this utility model, a second spring is fixedly installed inside the fan, and a push plate is fixedly installed at one end of the second spring, which can contact the modular air box.
[0010] As a preferred technical solution of this utility model, the top of the fan is provided with a long groove that communicates with the outside world, and one end of the pull rod can pass through to one side of the long groove and be fixedly connected with a pull ring.
[0011] As a preferred technical solution of this utility model, a first slider is fixedly installed on both sides of the limiting block, and a first groove adapted to the first slider is opened inside the fan.
[0012] As a preferred technical solution of this utility model, a filter screen is fixedly installed at the air inlet end of the fan.
[0013] As a preferred technical solution of this utility model, the modular air box has an internal concave cavity that communicates with the air outlet. The inner wall of the internal concave cavity is slidably connected to a baffle plate, which is adapted to the air outlet. The modular air box has a threaded connection to a hand-tightening screw, which can tighten the baffle plate.
[0014] As a preferred technical solution of this utility model, a second slider is fixedly installed on both sides of the push plate, and a second groove adapted to the second slider is opened inside the fan.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. When the modular air box needs to be removed, the operator only needs to pull the pull ring. The pull ring can drive the pull rod to move, and the pull rod can drive the limit block to move and squeeze the first spring. At the same time, the limit block can separate from the limit groove on the insert block. After the limit block separates from the limit groove on the insert block, the second spring can restore its elasticity and push the push plate to move outward. The push plate can push the modular air box to move outward and separate it from the fan, which makes it convenient for the operator to quickly remove the modular air box.
[0017] 2. When using this utility model, the operator can tighten the hand screw to adjust the position of the baffle, and then tighten the hand screw to fix the position of the baffle, so that the operator can flexibly adjust the opening or closing of the air outlet according to the number of terminal air boxes.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0025] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0028] like Figure 1 and Figure 2 As shown, this embodiment proposes a modular windmill filter unit, including a fan 1 and modular air boxes 2 arranged on the four sides of the fan 1. The interior of the modular air box 2 is provided with an air inlet and an air outlet 3 corresponding to the side air outlets of the fan 1. One side of the air outlet 3 of the modular air box 2 can be connected to a terminal air box through an air duct. A filter screen 12 is fixedly installed at the air inlet end of the fan 1. The filter screen 12 can reduce the entry of external dust and impurities into the fan 1.
[0029] like Figure 2 and Figure 3 As shown, a plug block 4 is fixedly installed on one side of the modular air box 2. The inside of the fan 1 is provided with a slot that matches the plug block 4. A first spring 5 is fixedly installed inside the fan 1. A limit block 6 is fixedly installed at one end of the first spring 5. A limit groove that matches the limit block 6 is provided inside the plug block 4. A pull rod 7 is fixedly installed on the inner side of the limit block 6.
[0030] like Figure 3 As shown, the top of the fan 1 has a long slot that connects to the outside. One end of the pull rod 7 can pass through one side of the long slot and is fixedly connected to a pull ring 10. The pull ring 10 allows the operator to easily pull the pull rod 7 to move. First sliders 11 are fixedly installed on opposite sides of the limiting block 6. The inside of the fan 1 has a first sliding groove that matches the first slider 11. The first slider 11 and the first sliding groove can limit the movement range of the limiting block 6 and make the limiting block 6 move more smoothly.
[0031] like Figure 2 and Figure 4 As shown, a second spring 8 is fixedly installed inside the fan 1. A push plate 9 is fixedly installed at one end of the second spring 8. The push plate 9 can contact the modular air box 2. When the modular air box 2 is connected to the fan 1, it can squeeze the push plate 9 to compress the second spring 8. When the limiting block 6 and the limiting groove on the insert block 4 separate, the second spring 8 can restore its elasticity and push the push plate 9 to move outward. The push plate 9 can push the modular air box 2 outward to separate it from the fan 1, making it convenient for workers to quickly remove the modular air box 2. Second sliders 15 are fixedly installed on both sides of the push plate 9. The fan 1 has a second sliding groove adapted to the second slider 15. The second slider 15 and the second sliding groove can limit the movement range of the push plate 9 and make the push plate 9 move more smoothly.
[0032] like Figure 2 and 5As shown, the modular air box 2 has an internal concave cavity that communicates with the air outlet 3. The inner wall of the internal concave cavity of the modular air box 2 is slidably connected to a baffle 13, which is adapted to the air outlet 3. The modular air box 2 has a threaded connection to a hand screw 14, which can tighten the baffle 13. In use, the operator can turn the hand screw 14 to adjust the position of the baffle 13, and then tighten the hand screw 14 to fix the position of the baffle 13. This makes it convenient for the operator to flexibly adjust the opening or closing of the air outlet 3 according to the number of terminal air boxes.
[0033] Specifically, when using this modular wind turbine filter unit: when it is necessary to remove the modular wind box 2, the operator only needs to pull the pull ring 10. The pull ring 10 can drive the pull rod 7 to move, and the pull rod 7 can drive the limiting block 6 to move and squeeze the first spring 5. At the same time, the limiting block 6 can separate from the limiting groove on the insert block 4 (e.g., Figure 3 As shown), when the limiting block 6 separates from the limiting groove on the insert block 4, the second spring 8 can restore its elasticity and push the push plate 9 to move outward. The push plate 9 can push the modular air box 2 to move outward and separate from the fan 1, making it convenient for workers to quickly remove the modular air box 2. This modular design makes disassembly very convenient and quick (as shown). Figure 2 , Figure 3 and Figure 4 (As shown); During use, the operator can loosen the hand screw 14 to adjust the position of the baffle 13, and then tighten the hand screw 14 to fix the position of the baffle 13. This allows the operator to flexibly adjust the opening or closing of the air outlet 3 according to the number of terminal air boxes (e.g., Figure 2 and Figure 5 (As shown).
[0034] All technical features in this embodiment can be freely combined according to actual needs.
[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
