[0002] As people's environmental awareness continues to improve, environmental testing has received more and more attention. Environmental testing is to monitor and analyze environmental quality in order to evaluate environmental conditions and predict future development trends. For some factories, since a lot of dust is easily generated during work, the dust content in the environment is relatively high. In order to further grasp the actual data of the dust content in the environment, it is necessary to collect the gas in the environment.
[0003] Existing detection agencies use dust filters to intercept dust during the gas collection process. For gases with high dust content, long-term collection will cause serious blockage of the dust filters. Therefore, they need to be replaced in time. The traditional replacement method requires stopping the collection work. If the collection is not stopped, internal gas leakage may occur, resulting in data deviation. Utility Model Content

[0007] As a further description of the above technical solution: the cross-sectional shape of the guide hole is a trapezoid, and the short side of the trapezoid is close to the collection box.
[0008] As a further description of the above technical solution: the side ends of the first dust filter and the second dust filter are both provided with a plurality of sealing strips, and the sealing strips slide along the outer end of the collecting box following the first dust filter or the second dust filter.

[0011] The utility model provides a dust environment detection device, which has the following beneficial effects:
[0012] 1. The first dust filter gradually approaches until it conflicts with the second dust filter, and pushes the second dust filter downward, and finally makes the second dust filter gradually separate from the guide strip. At this time, the air outlet is blocked by the first dust filter and continues to intercept dust particles.

There is no gap between the two, the sealing effect is good, and there is no need to stop the negative pressure pump, thereby improving the working efficiency of collecting gas compared with the prior art.
[0013] 2. When the first dust filter is ready to replace the second dust filter and move downward, it moves downward with the limit plate, and the limit plate enters the interior of the lock cylinder from the slot and squeezes the arc block. After the arc block is squeezed, it begins to compress the telescopic rod and the elastic member and move. The limit plate can continue to move until it moves below the limit plate. The limit plate also returns to its original state under the action of the elastic member and clamps the limit plate with the inner bottom of the lock cylinder to fix it, ultimately achieving the purpose of limiting the first dust filter. This can effectively prevent the collection box from being hit or shaking, and the first dust filter can still be stably installed.

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] Embodiment 1
[0024] Reference Figure 1-Figure 3 A dust environment detection device includes a collecting box 1, a negative pressure pump 2 is detachably connected to the side end of the collecting box 1, a supporting base 3 is fixedly connected to the side end of the collecting box 1, the negative pressure pump 2 is placed on the supporting base 3, an air outlet 5 is opened at the other end of the collecting box 1, a dust removal component 4 is arranged at the outer end of the collecting box 1 near the air outlet 5, the dust removal component 4 includes a first dust filter 6 and a second dust filter 7, the first dust filter 6 and the second dust filter 7 are fitted and slid up and down at the outer end of the collecting box 1 to realize alternating shielding of the air outlet 5.
[0025] As the preferred technical solution of this embodiment, both ends of the first dust filter 6 and the second dust filter 7 are fixedly connected with sliding bars 8, and the side ends of the sliding bars 8 are provided with guide holes 9. The outer end of the collecting box 1 is fixedly connected with a guide bar 10, and the outer wall of the guide bar 10 is adapted to the inner wall of the guide hole 9. There is friction damping between the sliding bar 8 and the guide bar 10, and the friction force between the two is greater than the gravity of the first dust filter 6 or the second dust filter 7.
[0026] As a preferred technical solution of this embodiment, the cross-sectional shape of the guide hole 9 is a trapezoid, and the short side of the trapezoid is close to the collection box 1 .
[0027] During operation, the collecting box 1 is placed in the environment to be tested. Since the environment is dusty, a dust filter component may be provided to prevent dust particles from leaving the collecting box 1 to collect the dust particles into the collecting box 1 .
[0028] In a dusty environment, long-term use of dust filter components to intercept dust will cause serious blockage of the dust filter components. Therefore, they need to be replaced in time. The traditional replacement method requires stopping the collection work, which makes the collection work inefficient.
[0029] In this case, a first dust filter 6 and a second dust filter 7 are arranged. When the second dust filter 7 located below becomes clogged after being used for a period of time, the first dust filter 6 is immediately inserted from the top of the guide bar 10 through the sliding bar 8. During the insertion process, the first dust filter 6 gradually approaches until it collides with the second dust filter 7, and then pushes the second dust filter 7 downward, and finally causes the second dust filter 7 to gradually detach from the guide bar 10. At this time, the air outlet 5 is blocked by the first dust filter 6, and the dust particles continue to be intercepted.
[0030] During the above-mentioned disassembly process of the second dust filter 7, the air outlet 5 is always blocked by the first dust filter 6 and the second dust filter 7, there is no gap between the two, and the sealing effect is good. That is to say, this method does not require stopping the negative pressure pump 2 and the collection work does not stop.
[0031] As a preferred technical solution of this embodiment, a self-locking component 11 is also provided on the dust removal component 4, and the self-locking component 11 includes a limiting plate 19 fixedly connected to the outer end of the sliding bar 8. A lock cylinder 15 is provided at the outer end of the collecting box 1, and the limiting plate 19 slides downward into the lock cylinder 15 and is limited.
[0032] Reference Figure 4 As the preferred technical solution of this embodiment, the outer end of the collection box 1 is fixedly connected to a support block 13, a rotating hole is opened on the support block 13, and a rotating shaft 14 is rotatably connected inside the rotating hole. One end of the rotating shaft 14 is fixedly connected to the anti-slip shaft 12, and the other end is fixedly connected to a lock cylinder 15. A slot 16 is opened on the top of the lock cylinder 15, and an elastic member 17 is rotatably connected to the inner side of the lock cylinder 15. The elastic member 17 includes a telescopic rod and a telescopic spring. A swivel is rotatably connected to the inner wall of the lock cylinder 15, and the telescopic rod is fixedly connected to the swivel. The telescopic rod is located inside the elastic member 17, and one end of the elastic member 17 is fixedly connected to an arc block 18. One end of the telescopic spring is fixedly connected to the end of the telescopic rod, and the other end is fixedly connected to the arc block 18.
[0033] In order to avoid vibration or shaking during the collection process, which may cause the first dust filter 6 or the second dust filter 7 to be positioned in a disadvantageous manner and the air outlet 5 to be not completely covered, a limiting self-locking component 11 is required. When the first dust filter 6 is ready to replace the second dust filter 7 and move downward, it moves downward with the limiting plate 19, and the limiting plate 19 enters the interior of the lock cylinder 15 from the slot 16 and squeezes the arc block 18. After the arc block 18 is squeezed, it begins to compress the telescopic rod and the elastic member 17 and move. The limiting plate 19 can continue to move until it moves below the limiting plate 19. The limiting plate 19 also returns to its original state under the action of the elastic member 17, and clamps the limiting plate 19 with the inner bottom of the lock cylinder 15 to fix it, finally achieving the purpose of limiting the first dust filter 6, which can effectively prevent the collection box 1 from being hit, or when it shakes itself, the first dust filter 6 can still be stably installed.
[0034] Subsequently, the replaced second dust filter 7 can be cleaned. After cleaning, the second dust filter 7 can replace the first dust filter 6. At this time, the anti-slip shaft 12 can be rotated so that the lock cylinder 15 can be rotated 180 degrees, with the slot 16 facing downward. Gently squeeze and push the first dust filter 6 to move downward, and the first dust filter 6 can be removed.
[0035] Embodiment 2
[0036] The difference between Example 2 and Example 1 is that the following technical features are added: the side ends of the first dust filter 6 and the second dust filter 7 are both provided with multiple sealing strips, and the sealing strips slide along the outer end of the collecting box 1 following the first dust filter 6 or the second dust filter 7.
[0037] Since there may still be a very small gap when the first dust filter 6 and the second dust filter 7 are slidingly fitted with the outer end of the collecting box 1, four sealing strips can be glued on one side of the first dust filter 6 and the second dust filter 7. The sealing strips form a U-shape, which can further improve the sealing effect during the disassembly and replacement process.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
