Moreover, during the production and manufacturing of PC construction, concrete construction waste can be used as raw material, and the development and implementation of resource processing and recycling of construction waste can better respond to the concept of recycling and environmental protection, and help build a modern infrastructure system.

[0003] When construction waste is processed, it needs to be piled up in a centralized manner as a raw material for concrete. In addition, dust is inevitably generated during operations such as transportation. In order to reduce the pollution of the environment by dust and to protect the working environment of the workers, additional dust reduction devices are needed to assist in dust reduction.

For example, the commonly used fog cannon, although the fog making effect of the fog cannon is relatively good, the fog cannon has a complex structure and is not conducive to use in large-scale factory buildings. Traditional spray dust reduction is mostly simple spraying, with poor fog making effect. The water droplets are too large to present a good water mist form, and the coverage range is small and the mode cannot be adjusted according to demand. It can only perform fixed-mode spraying, which is not flexible to use. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0029] Example 1

[0030] See also Figure 1-Figure 5 As shown, a spray dust reduction device for a concrete raw material warehouse comprises a main water pipe 1 fixed on the top of the raw material warehouse building, the main water pipe 1 needs to be connected to the water supply system and needs to be used with a pressure regulating valve, a spray pipe body 2 is installed at the bottom of the main water pipe 1, there are several spray pipe bodies 2, one spray pipe body 2 is a separate spray unit, which can perform spray dust reduction treatment for a certain range, a spray water channel 201 connected to the main water pipe 1 is arranged in the spray pipe body 2, the water flow in the main water pipe 1 can enter the spray pipe body 2 through the spray water channel 201, and an air inlet channel 202 connected to the spray water channel 201 is opened on the outer wall of the spray pipe body 2, The hole 202 can allow external air to enter the spray water channel 201 during spraying. The specific principle is that the water in the spray pipe flows at a high speed, which can attract air to mix in. The bottom end of the spray pipe body 2 is provided with a spray bottom hole 203 connected to the spray water channel 201, and a circumferential hole 204 connected to the spray water channel 201 is opened on the outer wall of the spray pipe body 2. A circumferential spray device 3 is provided on the outer sleeve of the spray pipe body 2. The circumferential spray device 3 is used to spray water to the surroundings, thereby expanding the spraying range. An adjustment mechanism 4 is installed on the circumferential spray device 3. The adjustment mechanism 4 is used to adjust the position of the circumferential spray device 3, thereby changing whether the circumferential spray device 3 is enabled.

[0031] A mixing chamber 205 is provided between the spray water channel 201 and the spray bottom hole 203. The mixing chamber 205 is located below the air inlet channel 202. Water and air can be mixed in the mixing chamber 205, which is beneficial to spraying. The circumferential hole 204 is located above the air inlet channel 202. The inner diameter of the spray water channel 201 above the circumferential hole 204 is R1, and the inner diameter of the spray water channel 201 below the circumferential hole 204 is R2. The inner diameter of the mixing chamber 205 is R3, and the aperture of the spray bottom hole 203 is R4. Comparing the numerical values, R3 is greater than R1, greater than R2, and greater than R4, which can improve the atomization effect of the water flow.

[0032] The circumferential spray device 3 includes a water distribution plate 301 movably mounted on the spray pipe body 2, a lower ring body 302 that fits the spray pipe body 2 is fixed to the bottom of the water distribution plate 301, and an upper ring body 303 is fixed to the upper surface of the water distribution plate 301 through a support plate, so that the water flow can be evenly distributed and sprayed.

[0033] A water retaining ring 304 is fixed on the side wall of the upper ring body 303, so that the water flow discharged from the circumferential hole 204 is limited between the water retaining ring 304 and the water dividing plate 301. The edges of the water dividing plate 301 all extend obliquely upward. The water flow can splash around after passing through the inclined water dividing plate 301, thereby forming an upward water flow layer, thereby expanding the spraying range and isolating noise through the sprayed water layer. The outer end of the air inlet channel 202 located on the outer wall of the spray pipe body 2 extends obliquely upward, and the aperture is larger than the inner end aperture connected to the spray water channel 201, so that the discharge of water can be limited.

[0034] The adjustment mechanism 4 includes an adjustment rod 401, a sealing disk 402 is fixed to the top of the adjustment rod 401, the sealing disk 402 is placed in the sealing cavity shell, and the bottom of the sealing disk 402 is fixedly connected to an adjustment spring 403 for pushing the sealing disk 402 to move. The bottom of the adjustment rod 401 is connected to the circumferential spray device 3 through a connecting frame 404, so that different spray modes can be triggered by using water flow pressure.

[0035] The connection mode of the adjustment mechanism 4 and the circumferential spray device 3 is rotational clamping. The sealing cavity shell is fixed at the bottom of the main water pipe 1 and is connected to the inside of the main water pipe 1. The connecting frame 404 includes a bottom plate fixed to the adjustment rod 401, and an annular hook plate is fixed to the bottom of the bottom plate. The upper ring body 303 is rotationally clamped with the annular hook plate through the top edge, which can not affect the rotational movement of the circumferential spray device 3, and at the same time ensure that the adjustment mechanism 4 can still control the movement of the circumferential spray device 3. The upper surface of the water diversion plate 301 is provided with guide twills, which can facilitate the water flow to push the water diversion plate 301 to rotate. The outer wall of the lower ring body 302 is fixed with a pressurized fan blade 5, and the outer wall of the spray pipe body 2 is fixed with a wind collecting shell 6. The edge of the wind collecting shell 6 extends upward to the outside of the pressurized fan blade 5.

[0036] When the utility model is in use, water flows from the main water pipe 1 into each spray pipe body 2, and then due to the different inner diameters of each section in the spray water channel 201, the water flow pressure will be different. When the water flows to the circumferential hole 204, the space is reduced, and the water can naturally flow to the circumferential holes 204 around. After continuing to flow, it can use the high flow rate to attract external air to enter, and then it can be mixed in the mixing chamber 205, and then the water is sprayed out in the spray bottom hole 203 in the form of mist.

[0037] The adjustment mechanism 4 can change the position of the circumferential spray device 3 according to the water pressure state. Specifically, when high-intensity dust reduction is required, the water pressure is increased so that the water flow pressure can be sufficient to push the adjustment rod 401 to compress the adjustment spring 403, and then the circumferential spray device 3 can be driven to descend until the water flows out through the circumferential hole 204, and the water diversion plate 301 can guide the discharge direction of the water flow, and finally make the water flow upward to form a continuous water layer. At the same time, the water flow impacts the water diversion plate 301 to drive the pressurized fan blades 5 to rotate. The pressurized fan blades 5 inhale external air through the wrapping restriction of the wind collecting shell 6, increase the gas pressure outside the air inlet duct 202, thereby enhancing the spray atomization effect.

[0038] Example 2

[0039] See also Figure 6-Figure 9 As shown, this embodiment proposes another implementation scheme of the combination of the circumferential spray device 3 and the adjustment mechanism 4 on the basis of Embodiment 1. The connection mode between the adjustment mechanism 4 and the circumferential spray device 3 is a fixed connection. The sealing chamber shell is embedded in the mixing chamber 205. The edge of the sealing disk 402 fits the inner wall of the sealing chamber shell. The bottom of the adjustment rod 401 passes through the spray bottom hole 203 and extends to the bottom of the spray pipe body 2. This makes it easy to control the position change of the circumferential spray device 3.

[0040] The connecting frame 404 includes a strip fixed to the adjusting rod 401, and the strip is fixedly connected to the bottom of the water distribution plate 301 through a fixing column. A limiting baffle 7 is fixed on the inner wall of the sealing chamber shell, and a snap-fitting convex strip 8 is provided on the outer wall of the spray pipe body 2. The lower ring body 302 is slidably snap-fitted on the snap-fitting convex strip 8, which can avoid unnecessary rotation of the circumferential spray device 3 and maintain the structural stability of the adjustment mechanism 4.

[0041] In the present embodiment, the two spray modes are separated, and the spray pipe body 2 without the circumferential spray device 3 is in a state of spraying when there is water. Similarly, when the water pressure is increased, the adjustment mechanism 4 can be triggered by the water pressure to move the position of the water diversion plate 301, and the limit baffle 7 is used to protect the adjustment spring 403 from being over-compressed. The provision of the snap-fit ​​convex strip 8 can limit the movement trajectory of the lower ring body 302, so that the circumferential spray device 3 and the adjustment mechanism 4 in this example are more stable when working together.
