Description

TECHNICAL FIELD

[0001] The utility model relates to dust suppression device's technical field, concretely relates to sandstone aggregate humidification dust suppression device. BACKGROUND

[0002] Sandstone aggregate includes sand, pebble, broken stone, block stone and material stone etc. The production process of sandstone aggregate mainly includes the following steps: mining, crushing, screening, transportation and storage. Among them, in the crushing process, a large amount of stone powder will be produced, and the stone powder will be scattered in the air during the transportation, stacking and transportation of sandstone aggregate, forming dust, which will affect human health and environment.

[0003] For example, a sandstone treatment machine dust suppression device is disclosed in Chinese patent (publication number: CN221680183U), which includes a rack, a damping mechanism is arranged at the bottom of the rack, a filter mechanism is arranged at the inner bottom of the rack, a cleaning mechanism is arranged in the filter mechanism, a conveyor is arranged at the inner side of the rack, a mounting plate is fixedly connected at the top of the rack, a pressing cylinder is arranged at one side of the mounting plate, the output end of the pressing cylinder penetrates through the mounting plate, a hydraulic rod is fixedly connected to the output end of the pressing cylinder, a support block is fixedly connected to one end of the hydraulic rod, a spray head is arranged at the bottom of the support block, a first sliding groove is formed at the top of the rack, a first sliding block is slidingly connected in the first sliding groove, one side of the first sliding block is fixedly connected with the support block, a fixed plate is fixedly connected to one side of the rack, a water storage tank is fixedly installed at the top of the fixed plate, a water pump is arranged in the water storage tank, the output end of the water pump is fixedly connected with a conveying pipe, one end of the conveying pipe penetrates through the water storage tank and extends to the inside of the support block and is communicated with the spray head.

[0004] In the above technical solution, water is sprayed from above the sandstone aggregate through the spray head, which can only cover the upper surface of the sandstone aggregate. During the transportation of the sandstone aggregate, the water sprayed on the surface slowly penetrates to the middle part of the sandstone aggregate, but the stone powder at the bottom of the sandstone aggregate is still in a dry state. When the sandstone aggregate falls from the discharge port of the conveyor into the next processing step, the stone powder at the bottom of the sandstone aggregate will be exposed to the air. As the sandstone aggregate falls, the stone powder mixed therein will be scattered in the air, forming dust, which will have a negative impact on human health and environment. The accumulation of stone powder will also cause wear and failure of the equipment, reducing the service life. UTILITY MODEL CONTENTS

[0008] In the utility model, the first spray mechanism is evenly distributed on the both sides of the conveying belt, and the first spray mechanism includes the first through pipe arranged above the upper side of the conveying belt.When the conveying belt runs to the upper side, the sand and gravel aggregate is located on the upper side of the conveying belt, and the water sprayed by the first through pipe can fully cover the belt surface of the conveying belt running to the upper side, so as to fully cover the sand and gravel aggregate on the upper side of the conveying belt running to the surface.The arrangement can ensure the uniformity of water spraying, thereby improving the dust suppression effect.The first through pipe is evenly distributed with a plurality of first nozzles along its axial direction, and the first nozzles are sprayed towards the upper side of the conveying belt.The first nozzles are evenly distributed on the first through pipe, so that the water spraying range is extensive and uniform, thereby effectively wetting the surface of the sand and gravel aggregate.When the water is sprayed on the sand and gravel aggregate by the first nozzle, the water droplets contact the stone powder on the surface of the sand and gravel aggregate, so that the stone powder is wetted.The wetted stone powder is not easy to be blown up by the wind, thereby effectively reducing the generation of dust.

[0009] The second spray mechanism is evenly distributed on the both sides of the conveying belt, and the second spray mechanism includes the second through pipe arranged below the lower side of the conveying belt, and the water sprayed by the second through pipe can fully cover the belt surface of the conveying belt running to the lower side when the conveying belt runs to the lower side.The second through pipe is evenly arranged with a plurality of second nozzles along its axial direction, and the second nozzles are sprayed towards the belt surface of the conveying belt running to the lower side.The second nozzles are evenly distributed on the second through pipe, so that the water spraying range is extensive and uniform, thereby effectively wetting the belt surface of the conveying belt running to the lower side.When the wetted belt surface runs to the upper side, the sand and gravel aggregate is placed on the wetted belt surface.Because the belt surface is already wet, the stone powder at the bottom of the sand and gravel aggregate combines with water, so that the stone powder is wetted.When the sand and gravel aggregate enters the subsequent processing step, the stone powder at the bottom of the sand and gravel aggregate is not easy to be blown up during the falling process, thereby effectively suppressing the dust.

[0010] In addition, after the stone powder combines with water, the stone powder becomes viscous and is easy to adhere to the surface of the conveying belt, and when the conveying belt runs to the lower side, the second nozzles can spray water to the belt surface of the conveying belt running to the lower side, and the sprayed water can directly flush away the stone powder adhered to the belt surface, thereby keeping the conveying belt clean.

[0013] In the utility model, both ends of each first pipe are connected with a first vertical rod, the first vertical rod provides stable support for the first pipe, so that the first pipe can keep in a fixed position above the conveying belt during water spraying, so that the first nozzle can accurately spray water on the sand and gravel aggregate on the conveying belt. One end of the first pipe is communicated with a first water pipe, which facilitates the injection of water into the first pipe and ensures that the first nozzle can continuously obtain water supply. The other end is closed to prevent water from flowing out of the end of the first pipe, ensure that all the water is sprayed out through the first nozzle, improve the utilization rate of water and reduce waste. At the same time, the closed end can maintain the water pressure in the first pipe, so that water can flow smoothly to each first nozzle, thereby ensuring that water can be uniformly sprayed from the first nozzle.

[0014] 3) The sand and gravel aggregate humidification and dust suppression device according to 2), wherein:

Since the first vertical rod is connected with the first pipe, the upward and downward movement of the first vertical rod drives the first pipe to move upward and downward correspondingly. When the amount of sand and gravel aggregate is small, the first pipe can move downward, so that it is closer to the sand and gravel aggregate, thereby more effectively spraying water and suppressing dust. When the amount of sand and gravel aggregate is large, the first pipe can move upward to avoid being blocked by the excessive sand and gravel aggregate, while ensuring the uniformity and effectiveness of water spraying.

[0018] Both ends of each second pipe are connected with a second vertical rod, the second vertical rod is fixedly connected with a support, one end of the second pipe is communicated with a second water pipe, and the other end of the second pipe is closed.

The other end is closed, preventing water from flowing out of the end of the second through pipe, ensuring that all water is sprayed out through the second nozzle, improving water utilization and reducing waste. At the same time, the closed end can maintain the water pressure in the second through pipe, allowing water to flow smoothly to each second nozzle, thereby ensuring that water can be uniformly sprayed from the second nozzle.

The second nozzles are uniformly distributed on the second through pipe, so that the water spraying range is extensive and uniform, thereby effectively wetting the belt surface on the lower side where the conveying belt runs. When the surface-wetted belt surface runs to the upper side, the sand and stone aggregates are placed on the wetted belt surface. Since the belt surface already has moisture, the stone powder at the bottom of the sand and stone aggregates combines with water and thus becomes wet.

[0033] The reference signs in the drawings of the specification include: a conveying belt 1, a first pipe 2, a first nozzle 3, a second pipe 4, a second nozzle 5, a first vertical rod 6, a first water pipe 7, a sleeve 8, an extension pump 9, a second vertical rod 10, a second water pipe 11, a main water pipe 12, a first water outlet 13, a second water outlet 14, a water tank 15, a suction pump 16, a driving wheel 17, a driven wheel 18, a rotating shaft 19, a servo motor 20.

[0034] Embodiment, see Figure 1 and Figure 2 As shown in the embodiment, the sand and gravel aggregate humidification and dust suppression device includes a support, and a conveying mechanism is arranged on the support. The conveying mechanism includes a conveying belt 1. A plurality of first spraying mechanisms are uniformly distributed on both sides of the conveying belt 1 along the conveying direction of the conveying belt 1. The first spraying mechanism includes a first pipe 2 arranged above the upper belt surface of the conveying belt 1. The first pipe 2 is uniformly distributed with a plurality of first nozzles 3 along the axis direction of the first pipe 2, which spray water towards the upper belt surface of the conveying belt 1. A plurality of second spraying mechanisms are uniformly distributed on both sides of the conveying belt 1 along the conveying direction of the conveying belt 1. The second spraying mechanism includes a second pipe 4 arranged below the lower belt surface of the conveying belt 1. The second pipe 4 is uniformly distributed with a plurality of second nozzles 5 along the axis direction of the second pipe 4, which spray water towards the lower belt surface of the conveying belt 1.

[0035] In the embodiment, the first spraying mechanisms are uniformly distributed on both sides of the conveying belt 1. The first spraying mechanism includes a first pipe 2 arranged above the upper belt surface of the conveying belt 1. When the conveying belt 1 runs to the upper side, the sand and gravel aggregate is located on the upper belt surface of the conveying belt 1, and the water sprayed by the first pipe 2 can fully cover the belt surface of the conveying belt 1 running to the upper side, thereby fully covering the sand and gravel aggregate on the upper belt surface of the conveying belt 1 running to the upper side. This arrangement can ensure the uniformity of water spraying, thereby improving the dust suppression effect. The first pipe 2 is uniformly distributed with a plurality of first nozzles 3 along the axis direction of the first pipe 2, which spray water towards the upper belt surface of the conveying belt 1. The first nozzles 3 are uniformly distributed on the first pipe 2, which can widely and uniformly spray water, thereby effectively wetting the surface of the sand and gravel aggregate. When the water is sprayed onto the sand and gravel aggregate through the first nozzles 3, the water droplets will contact the stone powder on the surface of the sand and gravel aggregate, thereby wetting the stone powder. The wetted stone powder is no longer easily blown up by the wind, thereby effectively reducing the generation of dust.

[0036] The second spraying mechanism is uniformly distributed on both sides of the conveying belt 1, and the second spraying mechanism includes a second pipe 4 arranged below the lower side of the conveying belt 1. When the conveying belt 1 runs to the lower side, the water sprayed by the second pipe 4 can fully cover the belt surface of the conveying belt 1 running to the lower side. The second pipe 4 is uniformly arranged with a plurality of second nozzles 5 along the axial direction of the second pipe 4, and the second nozzles 5 spray water towards the belt surface of the conveying belt 1 running to the lower side. The second nozzles 5 are uniformly distributed on the second pipe 4, which can make the spraying range of water extensive and uniform, so as to effectively wet the belt surface of the conveying belt 1 running to the lower side. When the surface-wetted belt surface runs to the upper side, the sand and gravel aggregate is placed on the wetted belt surface. Since the belt surface already has moisture, the stone powder at the bottom of the sand and gravel aggregate will combine with water and become wet. When the sand and gravel aggregate enters the subsequent processing step, it will not be raised during its falling process because the stone powder at the bottom has already adhered to water, thereby effectively inhibiting dust raising.

[0037] In addition, after the stone powder combines with water, the stone powder will become viscous and easily adhere to the surface of the conveying belt 1. When the conveying belt 1 runs to the lower side, the second nozzles 5 can spray water to the belt surface of the conveying belt 1 running to the lower side, and the sprayed water can directly flush away the stone powder adhered to the belt surface, thereby keeping the conveying belt clean.

[0038] Secondly, the two ends of each first pipe 2 are respectively connected with a first vertical rod 6, one end of the first pipe 2 is communicated with a first water pipe 7, and the other end of the first pipe 2 is closed.

[0039] In this embodiment, the two ends of each first pipe 2 are respectively connected with a first vertical rod 6, which provides stable support for the first pipe 2, so that it can remain in a fixed position above the conveying belt 1 during water spraying, thereby enabling the first nozzles 3 to accurately aim at the sand and gravel aggregate on the conveying belt 1 for water spraying. One end of the first pipe 2 is communicated with a first water pipe 7, which facilitates the injection of water into the first pipe 2, ensuring that the first nozzles 3 can continuously obtain water supply. The other end is closed to prevent water from flowing out of the end of the first pipe 2, ensuring that all water is sprayed out through the first nozzles 3, thereby improving water utilization and reducing waste. At the same time, the closed end can maintain the water pressure in the first pipe 2, so that water can flow smoothly to each first nozzle 3, thereby ensuring that water can be uniformly sprayed out of the first nozzles 3.

[0040] Referring to Figure 3 As shown in the figure, a sleeve 8 is externally sleeved on each first vertical rod 6, and a telescopic pump 9 is arranged in the sleeve 8. The telescopic rod of the telescopic pump 9 is fixedly connected with the bottom of the first vertical rod 6, and the first vertical rod 6 can slide up and down in the sleeve 8 in the height direction.

[0041] In this embodiment, the telescopic rod of each telescopic pump 9 is fixedly connected with the bottom of the first vertical rod 6. When the telescopic pump 9 performs the elongation action, it will push the first vertical rod 6 to move upward. When the telescopic pump 9 performs the shortening action, it will drive the first vertical rod 6 to move downward. Since the first vertical rod 6 is connected with the first through pipe 3, the upward and downward movement of the first vertical rod 6 will drive the first through pipe 2 to move upward and downward correspondingly. When the amount of sand and stone aggregate is small, the first through pipe 2 can move downward so as to be closer to the sand and stone aggregate, thereby more effectively performing the water spraying dust suppression. When the amount of sand and stone aggregate is large, the first through pipe 2 can move upward to avoid being blocked by the excessive sand and stone aggregate, while ensuring the uniformity and effectiveness of water spraying.

[0042] Secondly, the two ends of each second through pipe 4 are respectively connected with a second vertical rod 10, the second vertical rod 10 is fixedly connected with the support, one end of the second through pipe 4 is communicated with a second water pipe 11, and the other end of the second through pipe 4 is closed.

[0043] In this embodiment, the two ends of each second through pipe 4 are respectively connected with a second vertical rod 10, the second vertical rod 10 is fixedly connected with the support, and the second through pipe 4 is provided with stable support, so that it can be kept at a fixed position below the running belt surface of the conveying belt 1 in the water spraying process, thereby enabling the second nozzle 5 to accurately aim at the running belt surface of the conveying belt 1 to spray water. One end of the second through pipe 4 is connected with the second water pipe 11, which facilitates the injection of water into the second through pipe 4 and ensures that the second nozzle 5 can continuously obtain water supply. The other end is closed to prevent water from flowing out of the end of the second through pipe 4, ensure that all the water is sprayed out through the second nozzle 5, improve the utilization rate of water and reduce waste. At the same time, the closed end can maintain the water pressure in the second through pipe 4, so that the water can flow smoothly to each second nozzle 5, thereby ensuring that the water can be uniformly sprayed out of the second nozzle 5.

[0044] Referring to Figure 4 As shown in the figure, the bottom of the support is provided with a main water pipe 12, a plurality of first water outlets 13 and a plurality of second water outlets 14 are uniformly distributed along the axial direction of the main water pipe 12. Each first water outlet 13 is respectively corresponding to and communicated with the first water pipe 7, and each second water outlet 14 is respectively corresponding to and communicated with the second water pipe 11. One end of the main water pipe 12 is closed, and the other end of the main water pipe 12 is connected with a water tank 15 through a hose, and a suction pump 16 is connected on the hose.

[0045] In the embodiment, the support is provided with a main water pipe 12, one end of the main water pipe 12 is connected with the water tank 15 through a hose, the hose is provided with a suction pump 16, the suction pump 16 can suck the water in the water tank 15 and deliver it into the main water pipe 12. The other end of the main water pipe 12 is closed, which can prevent the water from flowing out of the end, avoiding the waste of water resources. The main water pipe 12 is uniformly provided with a plurality of first water outlets 13 and a plurality of second water outlets 14 along the axial direction thereof. The water in the main water pipe 12 flowing out through the plurality of first water outlets 13 respectively enters the corresponding and communicating first water pipes 7; the water in the main water pipe 12 flowing out through the plurality of second water outlets 14 respectively enters the corresponding and communicating second water pipes 11, so that the water in the main water pipe 12 can be uniformly distributed into each first water pipe 7 and second water pipe 11, ensuring that each first water pipe 8 and second water pipe 4 can obtain continuous water flow supply.

[0046] In addition, the conveying mechanism further comprises a driving wheel 17 and a driven wheel 18, the conveying belt 1 is wound between the driving wheel 17 and the driven wheel 18, the driving wheel 17 is coaxially provided with a rotating shaft 19, and the end of the rotating shaft 19 is connected with a servo motor 20.

[0047] In the embodiment, the servo motor 20 is started to drive the rotating shaft 19 to rotate, and then drive the driving wheel 17 to rotate. The conveying belt 1 is wound between the driving wheel 17 and the driven wheel 18, and there is friction between the surface of the conveying belt 1 and the driving wheel 17, so that the driving wheel 17 rotates to drive the conveying belt 1 to start running. Similarly, there is friction between the surface of the conveying belt 1 and the driven wheel 18, so that the driven wheel 18 also rotates while the conveying belt 1 is running. Thus, the continuity and stability of the entire conveying process can be ensured.

[0048] In the embodiment, when the conveying belt 1 runs to the upper side, the sand and gravel aggregate is located on the upper side of the conveying belt 1, and the water sprayed by the first water pipe 2 can fully cover the sand and gravel aggregate on the upper side of the conveying belt 1, thereby fully covering the sand and gravel aggregate on the upper side of the conveying belt 1. This arrangement can ensure the uniformity of water spraying, thereby improving the dust suppression effect. The first water pipe 2 is uniformly provided with a plurality of first nozzles 3 along the axial direction thereof, and the first nozzles 3 spray water towards the upper side of the conveying belt 1. When the water is sprayed onto the sand and gravel aggregate through the first nozzles 3, the water droplets will contact the stone powder on the surface of the sand and gravel aggregate, making it wet. The wet stone powder is no longer easy to be blown up by the wind, thereby effectively reducing the generation of dust.

[0049] Secondly, when the conveying belt 1 runs to the lower side, the water sprayed by the second pipe 4 can fully cover the belt surface of the conveying belt 1 running to the lower side. The second pipe 4 is uniformly provided with a plurality of second nozzles 5 along the axial direction of the second pipe 4, and the second nozzles 5 spray water towards the belt surface of the conveying belt 1 running to the lower side. The second nozzles 5 are uniformly distributed on the second pipe 4, which can make the spraying range of water extensive and uniform, so as to effectively wet the belt surface of the conveying belt 1 running to the lower side. When the surface-wetted belt surface runs to the upper side, the sand and stone aggregates are placed on the wetted belt surface. Since the belt surface already has water, the stone powder at the bottom of the sand and stone aggregates will combine with water and thus become wet. When the sand and stone aggregates enter the subsequent processing steps, they will not be raised during falling due to the stone powder at the bottom being already sticky with water, so as to effectively inhibit dust raising.

[0050] In addition, the first pipe 2 can move up and down. When the amount of sand and stone aggregates is small, the first pipe 2 moves downward to be closer to the sand and stone aggregates, so as to more effectively spray water and suppress dust. When the amount of sand and stone aggregates is large, the first pipe 2 moves upward to avoid being blocked by the excessive sand and stone aggregates and to ensure the uniformity and effectiveness of water spraying.

[0051] The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of characteristics in the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
