Description

Technical Field

[0001] The utility model relates to the technical field of environmental detection sampling, and in particular to an air fluoride sampler for environmental detection. Background Art

[0002] An air fluoride sampler is an instrument used to collect and measure the concentration of fluoride in the air. Air fluoride samplers are usually used in environmental monitoring, industrial emission control, public health and other fields to monitor and evaluate the concentration level of fluoride in the air, thereby protecting the environment and human health. The air inlet of the existing air fluoride sampler is generally not equipped with a filtering structure, which makes it easy for particulate matter mixed in the outside air to enter the sampler, which not only pollutes the sampling medium, but also causes the sampling system to be blocked, affecting the collection efficiency of fluoride. Utility Model Content

[0003] The main purpose of the utility model is to provide an air fluoride sampler for environmental detection, which can effectively solve the problem that the air inlet of the air fluoride sampler in the background technology is generally not provided with a filtering structure, resulting in that particulate matter mixed in the external air can easily enter the interior of the sampler, which not only pollutes the sampling medium, but also causes the sampling system to be blocked, affecting the collection efficiency of fluoride.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] An air fluoride sampler for environmental detection comprises a sampling barrel, an air intake pipe is fixedly mounted on the upper end of the sampling barrel, and an air intake fan is arranged in the air intake pipe;

[0006] The sampling barrel body is fixedly installed with an air outlet pipe, and the air inlet pipe and the air outlet pipe are both provided with sealing valves;

[0007] A positioning frame is provided at one end of the air intake pipe, and a card slot is provided on the lower surface of the two positioning frames, and the card slot is inserted and matched with the air intake pipe. A filter plate is fixedly installed on the lower surface of the two positioning frames, and the filter plate is arranged inside the air intake pipe;

[0008] A sealing ring is fixedly installed inside the air intake pipe.

[0009] Preferably, the intake pipe body is fixedly installed with two support frames, and screws are rotatably installed on the upper surfaces of the two support frames. Moving plates are threadedly arranged on the two screw rod bodies, and moving grooves are penetrated on the surfaces of the opposite sides of the two moving plates, and moving blocks are slidably arranged in the two moving grooves.

[0010] Preferably, plug blocks are fixedly mounted on the lower surfaces of the two moving blocks;

[0011] Slots are provided on the upper surfaces of the two positioning frames.

[0012] Preferably, limit plates are fixedly mounted on both sides of the two moving blocks.

[0013] Preferably, a slide bar is fixedly mounted on the upper surface of the two support frames, and the two movable plates are respectively slidably arranged on one side of the corresponding slide bar body.

[0014] Preferably, the lower ends of the two screw rods pass through corresponding support frames respectively and are fixedly mounted with rotating wheels.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] (1) The staff places the filter plate inside the air inlet pipe so that the filter plate fits with the sealing ring. At this time, the card slot fits with the wall of the air inlet pipe, so that the filter plate is fixed in a horizontal position. Then the staff opens the sealing valve inside the air inlet pipe and starts the air intake fan. The outside air enters the sampling barrel through the filter plate. The filter plate filters the particles mixed in the outside air to prevent these particles from entering the sampler, preventing the sampling medium from being contaminated. At the same time, it also avoids clogging of the sampling system, thereby ensuring the collection efficiency of fluoride. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 5 As shown, the embodiment of the utility model proposes an air fluoride sampler for environmental detection, comprising a sampling barrel 1, an air intake pipe 2 is fixedly installed on the upper end of the sampling barrel 1, and an air intake fan 3 is arranged in the air intake pipe 2;

[0025] The sampling barrel 1 is fixedly provided with an air outlet pipe 4, and both the air inlet pipe 2 and the air outlet pipe 4 are provided with sealing valves;

[0026] A positioning frame 5 is provided at one end of the air intake pipe 2. A card slot 6 is provided on the lower surface of the two positioning frames 5. The card slot 6 is inserted and matched with the air intake pipe 2. A filter plate 7 is fixedly installed on the lower surface of the two positioning frames 5. The filter plate 7 is arranged inside the air intake pipe 2.

[0027] A sealing ring 18 is fixedly installed inside the air intake pipe 2 .

[0028] The staff places the filter plate 7 inside the air inlet pipe 2 so that the filter plate 7 fits with the sealing ring 18. At this time, the slot 6 fits with the wall of the air inlet pipe 2, so that the filter plate 7 is fixed in a horizontal position. Then the staff opens the sealing valve inside the air inlet pipe 2, and then starts the air intake fan 3. The outside air enters the sampling barrel 1 through the filter plate 7. The filter plate 7 filters the particles mixed in the outside air to prevent these particles from entering the sampler, preventing the sampling medium from being contaminated, and also avoiding clogging of the sampling system, thereby ensuring the collection efficiency of fluoride.

[0029] In another embodiment of the utility model, two support frames 8 are fixedly installed on the body of the intake pipe 2, and screw rods 9 are rotatably installed on the upper surfaces of the two support frames 8. The two screw rods 9 are threadedly provided with movable plates 10 on the shafts, and movable grooves 11 are penetrated through the surfaces of the opposite sides of the two movable plates 10, and movable blocks 12 are slidably provided in the two movable grooves 11.

[0030] The staff rotates the screw 9 to drive the movable plate 10 down by screwing it in, so that the movable block 12 can press the positioning frame 5, so that the filter plate 7 can fit tightly with the sealing ring 18, thereby preventing particles from passing through the gap between the filter plate 7 and the sealing ring 18.

[0031] In another embodiment of the utility model, an insert block 13 is fixedly mounted on the lower surface of the two moving blocks 12;

[0032] Slots 14 are formed on the upper surfaces of the two positioning frames 5 .

[0033] Under the interpenetration of the slot 14 and the insert block 13, the positioning effect of the filter plate 7 is enhanced to prevent it from moving due to external collision.

[0034] In another embodiment of the present invention, limiting plates 15 are fixedly installed on both sides of the two moving blocks 12 .

[0035] The limiting plate 15 is provided to prevent the moving block 12 from being separated from the moving groove 11 .

[0036] In another embodiment of the present invention, a slide bar 16 is fixedly mounted on the upper surfaces of the two support frames 8 , and the two movable plates 10 are slidably disposed on one side of the corresponding slide bar 16 .

[0037] By providing the slide bar 16 , when the screw rod 9 rotates, the moving plate 10 can move along the direction of the slide bar 16 , thereby enhancing the stability of the moving plate 10 when moving.

[0038] In another embodiment of the present invention, the lower ends of the two screw rods 9 pass through the corresponding support frames 8 and are fixedly mounted with rotating wheels 17 .

[0039] The rotating wheel 17 is provided to facilitate the staff to rotate the screw rod 9 .

[0040] The working principle of this air fluoride sampler for environmental testing:

[0041] When in use, the staff places the filter plate 7 inside the air inlet pipe 2 so that the filter plate 7 fits with the sealing ring 18. At this time, the slot 6 fits with the wall of the air inlet pipe 2, so that the filter plate 7 is fixed in a horizontal position. Then the staff opens the sealing valve inside the air inlet pipe 2, and then starts the air intake fan 3. The outside air enters the sampling barrel 1 through the filter plate 7. The filter plate 7 filters the particles mixed in the outside air to prevent these particles from entering the sampler, preventing the sampling medium from being contaminated, and also avoiding clogging of the sampling system, thereby ensuring the collection efficiency of fluoride.

[0042] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
