[0032] The embodiment of the utility model provides an atmospheric dust reduction cylinder which can automatically replenish liquid. Liquid is automatically replenished into the dust reduction cylinder through a liquid storage tank, so that the liquid in the dust reduction cylinder is maintained within a certain range, thereby preventing frequent manual replenishment of liquid into the dust reduction cylinder and being easy to use.

[0033] Combine the following Figure 1-Figure 4 The technical solution provided by the utility model is described in more detail.

[0034] Embodiment 1:

[0035] The utility model provides an atmospheric dust reduction cylinder 1 with automatic liquid replenishment, comprising a support frame 3, a dust reduction cylinder 1 and a liquid storage tank 2, wherein: a first mounting groove 4, a liquid replenishment channel 5 and a second mounting groove 6 are provided on the support frame 3, and both ends of the liquid replenishment channel 5 are respectively connected with the first mounting groove 4 and the second mounting groove 6; a liquid inlet 11 is provided at the bottom of the dust reduction cylinder 1, the dust reduction cylinder 1 and the second mounting groove 6 are detachably connected, and the liquid inlet 11 is connected with the liquid replenishment channel 5; a sealing component is provided at the liquid outlet of the liquid storage tank 2, and when the liquid outlet of the liquid storage tank 2 is fixed in the first mounting groove 4, the sealing component can open the liquid outlet of the liquid storage tank 2, and the liquid in the liquid storage tank 2 can flow into the dust reduction cylinder 1 through the liquid replenishment channel 5 under the action of the atmospheric pressure difference.

[0036] The liquid in the liquid storage tank 2 and the dust suppression cylinder 1 is an ethylene glycol aqueous solution.

[0037] The support frame 3 makes the dust reduction cylinder 1 be at a height of 8m to 15m from the ground. When the dust reduction cylinder 1 is moved, the overall structure can be moved by moving the support frame 3, which is convenient for moving.

[0038] When the liquid outlet of the liquid storage tank 2 is inserted into the first mounting groove 4 or threadedly connected to the first mounting groove 4, the liquid storage tank 2 is connected to the first mounting groove 4, the liquid replenishing channel 5, the second mounting groove 6, and the dust reduction cylinder 1. According to the hydraulic pressure equality at the same horizontal position, under the action of the atmospheric pressure difference, the liquid in the liquid storage tank 2 can enter the dust reduction cylinder 1 to replenish the liquid in the dust reduction cylinder 1.

[0039] The automatic refillable atmospheric dust reduction cylinder 1 of the present embodiment has a sealing component that can prevent liquid from flowing out when the liquid storage tank 2 is inverted. When the liquid outlet of the liquid storage tank 2 is fixed in the first mounting groove 4, the sealing component can open the liquid outlet of the liquid storage tank 2, and the liquid in the liquid storage tank can flow into the dust reduction cylinder 1 through the refilling channel 5 under the action of the atmospheric pressure difference; the automatic refillable atmospheric dust reduction cylinder 1 automatically refills liquid to the dust reduction cylinder 1 through the liquid storage tank 2, so that the liquid in the dust reduction cylinder 1 is maintained within a certain range, thereby preventing frequent manual refilling of liquid to the dust reduction cylinder 1, and is easy to use.

[0040] As an alternative embodiment, see Figure 2 , Figure 4 As shown, the sealing assembly includes a sealing ball 71. When the liquid storage tank 2 is inverted, the sealing ball 71 is sealed with the liquid outlet of the liquid storage tank 2. A protrusion 41 is fixed in the first mounting groove 4. When the liquid outlet of the liquid storage tank 2 is snapped into the first mounting groove 4, the protrusion 41 can lift the sealing ball 71, thereby opening the liquid outlet of the liquid storage tank 2.

[0041] As shown in FIG4 , when the liquid storage tank 2 is inverted, the seal blocks the liquid outlet of the liquid storage tank 2 to prevent the liquid from flowing out of the liquid storage tank 2 .

[0042] See also Figure 1 and Figure 2 As shown, when the liquid outlet of the liquid storage tank 2 is inserted into the first mounting groove 4, the protrusion 41 can lift the sealing ball 71, and the sealing ball 71 no longer closes the liquid outlet. The liquid outlet of the liquid storage tank 2 is opened, and the liquid can flow from the liquid storage tank 2 into the first mounting groove 4, the liquid replenishing channel 5, the second mounting groove 6, and enter the dust reduction cylinder 1 to replenish the dust reduction cylinder 1 with liquid.

[0043] As an alternative embodiment, see Figure 2 and Figure 4 As shown, the sealing assembly of this embodiment further includes a blocking plate 72, which is located on the side of the sealing ball 71 away from the liquid outlet of the liquid storage tank 2, and is used to prevent the sealing ball 71 from entering the tank body of the liquid storage tank 2. The function of the above-mentioned blocking plate 72 is to prevent the sealing ball 71 from entering the tank body.

[0044] The density of the sealing ball 71 is greater than the density of the liquid in the liquid storage tank 2 .

[0045] As an alternative embodiment, see Figure 4 As shown, the sealing ball 71 and the blocking limit plate 72 are located at the tank mouth of the liquid storage tank 2 .

[0046] When the liquid in the liquid storage tank 2 is used up, a new liquid storage tank 2 can be replaced or liquid can be added to the liquid storage tank 2 .

[0047] As an alternative embodiment, see Figure 1-Figure 3As shown, the first mounting groove 4, the liquid replenishing channel 5 and the second mounting groove 6 are in a U-shaped structure.

[0048] This structure can ensure that liquid can flow from the liquid storage tank 2 into the first installation groove 4, the liquid replenishing channel 5, the second installation groove 6, and into the dust reduction cylinder 1 to replenish the dust reduction cylinder 1.

[0049] As an optional implementation, the first installation groove 4, the liquid infusion channel 5 and the second installation groove 6 are directly formed on the upper surface of the support frame 3. No extra connection structure is required, and the structure is compact and simple.

[0050] As an alternative embodiment, see Figure 3 As shown, a groove 12 is provided at the bottom of the dust suppression cylinder 1. The groove 12 is located at the periphery of the liquid inlet 11. The groove 12 is plugged into the groove of the second mounting groove 6, thereby connecting the liquid inlet 11 with the second mounting groove 6 and the liquid replenishing channel 5.

[0051] The matching structure of the groove 12 of the dust reduction cylinder 1 and the second mounting groove 6 can realize the clamping connection between the dust reduction cylinder 1 and the second mounting groove 6, so that the dust reduction cylinder 1 is fixed in the second mounting groove 6, ensuring that the second mounting groove 6 and the dust reduction cylinder 1 are connected.

[0052] In order to further improve the fixing stability of the dust suppression cylinder 1, see Figure 1 As shown, as an optional implementation, a clamp 8 is fixed on the support frame 3, and the clamp 8 is located beside the second mounting groove 6, and is used to clamp and fix the dust suppression cylinder 1.

[0053] The clamp 8 is a common clamp 8 structure, which will not be described in detail here.

[0054] The dust reduction cylinder 1 is clamped in the second mounting groove 6 , and the clamp 8 clamps and fixes the dust reduction cylinder 1 , so that the dust reduction cylinder 1 is firmly fixed on the support frame 3 .

[0055] As an optional implementation, a handle 21 is provided on the liquid storage tank 2 to facilitate the user to carry it and replace the liquid storage tank 2.

[0056] As an alternative embodiment, see Figure 1 As shown, when the liquid storage tank 2 is clamped in the first installation groove 4 , the top of the liquid storage tank 2 is lower than the top of the dust suppression cylinder 1 .

[0057] In other words, the top of the dust reduction cylinder 1 is at the highest position, which prevents other components from blocking the cylinder mouth position of the dust reduction cylinder 1 and ensures that the dust reduction cylinder 1 can sample normally.

[0058] Embodiment 2:

[0059] The difference between this embodiment 2 and embodiment 1 is that: Figure 5As shown, the sealing assembly also includes a shell 70 , which is threadedly connected to the tank mouth of the liquid storage tank 2 , and a sealing ball 71 and a blocking limit plate 72 are located inside the shell 70 .

[0060] When the liquid in the liquid storage tank 2 is used up, the outer shell 70 is removed and the outer shell 70 is threadedly connected to another new liquid storage tank 2 filled with liquid.

[0061] In the description of this specification, specific features, structures or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0062] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model.
