Description

Technical Field

[0001] The present invention relates to the technical field of stone cleaning, in particular to a dust suppression and cleaning device for a stone processing plant and a use method thereof. Background Art

[0002] During the construction period of marine engineering, the main construction contents include embankments, land formation and foundation treatment, hydraulic engineering, etc., which are specifically divided into embankment engineering, land formation and foundation treatment engineering, hydraulic structures, dredging, reef blasting, anchorage improvement, mountain excavation, slope support and other sub-projects. Among them, mountain excavation projects produce a large amount of earth and stone, and new gravel processing plants need to be built nearby to reduce the distance of stone transportation.

[0003] The processing plant processes raw materials into gravel through crushing, vibrating screening and cone workshops. However, since the gravel itself is dry and contains a large amount of dust and other pollutants, the processing plant lacks wind protection. The ambient wind easily causes dust to spread and pollute the surrounding environment. Currently, the control of dust pollution mainly relies on manual and spray systems to suppress and clean dust-producing points.

[0004] Chinese patent application number CN201821827755.9 discloses a dust suppression device for a concrete production space, comprising a base, a support column fixedly mounted on the top of the base, a water tank provided at the upper end of the inner portion of the support column, a water outlet pipe fixedly connected to the right side of the water tank, a fine water mist nozzle evenly mounted at the bottom of the water outlet pipe, a cleaning box provided inside the support column, a screen provided inside the cleaning box, a shock-absorbing spring provided on the lower end surface of the cleaning box, and a support member provided at the lower end of the shock-absorbing spring.

[0005] The Chinese patent application number CN201921678705.3 discloses a mine stone cleaning device, including an outer cover frame, a perforated plate is provided on the inner side of the outer cover frame, the perforated plate is welded and fixed to the outer cover frame, a conveyor belt is provided above the perforated plate, a bent plate frame is provided above the conveyor belt, the bent plate frame is fixedly connected to the outer cover frame through a bracket, a blower is provided at the top of the outer cover frame, a water trough is provided at the bottom end of the outer cover frame, a hollow gear shaft is installed on the bent plate frame, a hollow brush cylinder is provided at the bottom end of the hollow gear shaft, and an air outlet is provided on the hollow brush cylinder.

[0006] However, when the stones contain a lot of dust, the above cleaning device cannot remove the small dust particles in advance, resulting in the stone cleaning consuming more water and electricity resources and having a low stone cleaning efficiency.

[0007] In addition, during the storage stage after processing, dirt such as lumps with strong adhesion will form on the stones or in the gaps between the stones. The distribution points of these dirt in the stones are not only difficult to determine, but also the dirt is difficult to form sufficient contact with the spray water, resulting in incomplete cleaning of the stones, which affects the subsequent reprocessing of the stones.

[0008] Therefore, the present invention proposes a dust suppression and cleaning device for a gravel processing plant and a method of using the same to solve the above problems. Summary of the Invention

[0036] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein may be combined with each other.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from the description. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0038] Example 1: Please refer to Figures 1 to 6 The present embodiment discloses a dust suppression and cleaning device for a gravel processing plant, comprising a support platform 1, a water reservoir 2 and a supporting plate 3. The water reservoir 2 is provided on the top of the support platform 1. One end of the supporting plate 3 is rotatably connected to a rotating seat 102 through a rotating shaft 103. The rotating seat 102 is fixedly connected to the water reservoir 2. The end of the supporting plate 3 away from the rotating seat 102 is movably hinged to the movable end of a cylinder 104. The fixed end of the cylinder 104 is rotatably connected to the bottom of the water reservoir 2. The supporting plate 3 is coordinated with the rotating seat 102 and the cylinder 104 is extended to make the supporting plate 3 flip around the rotating seat 102 and the rotating shaft 103 as the center. The inclination angle of the supporting plate 3 is controlled by the telescopic length of the cylinder 104.

[0039] A support frame 303 is provided on the top of the supporting plate 3, and a spray pipe 302 and an angle-adjustable rotating plate 501 are provided on the inner side of the support frame 303. A spray head 3021 is provided on the spray pipe 302, and the rotating plate 501 is located directly below the spray pipe 302. The support frame 303 installs and supports the spray pipe 302.

[0040] Specifically, a motor 502 and an electric telescopic rod 503 are provided on the inner side of the support frame 303. The rotating end of the motor 502 is fixedly connected to the middle of the rotating plate 501, and the telescopic end of the electric telescopic rod 503 is fixedly connected to the motor 502. The fixed end of the electric telescopic rod 503 is provided on the inner side of the support frame 303. The electric telescopic rod 503 controls the horizontal height of the motor 502 and the rotating plate 501, and adjusts the distance between the rotating plate 501 and the sprinkler head 3021 and the supporting plate 3. A lifting groove 5021 is provided on the inner side of the support frame 303, and a limit block is provided at one end of the motor 502 close to the support frame 303. The limit block corresponds to the lifting groove 5021. The cooperation between the lifting groove 5021 and the limit block provides a limiting effect when the motor 502 moves up and down, thereby maintaining the stability of the motor 502 and the rotating plate 501 when they move up and down. The length of the rotating plate 501 is adapted to the width of the internal groove of the supporting plate 3.

[0041] A cover body 401 is provided on the top of the supporting plate 3, and a feed door 4011 is movably installed on the top of one end of the cover body 401. The feed door 4011 is hingedly connected to the cover body 401, and a torsion spring is provided at the hinge between the feed door 4011 and the cover body 401. Through the setting of the torsion spring, the stone presses down the feed door 4011 to open the feed door 4011. After the stone falls onto the supporting plate 3, the rebound force of the torsion spring itself resets the feed door 4011 and forms a closure on one end of the cover body 401 to prevent dust from flowing out.

[0042] The top of the cover body 401 is connected to a suction pipe 403 through a suction hood 402. The suction pipe 403 is provided with a suction fan and a filter box. After the suction fan is started, the gas and dust in the cover body 401 are continuously discharged outward through the suction pipe 403, and the dust is blocked and collected by the filter box.

[0043] Among them, a connecting cover 4012 is provided on the outside of the feeding door 4011, and a connecting head is provided on the connecting cover 4012. The connecting cover 4012 is connected to the feeding pipe through the connecting head. The setting of the cover body 401 and the connecting cover 4012 can avoid the influence of the environmental wind on the stone due to the lack of windproof ability of the stone processing plant. Specifically, the stone with dust is separated from the outside world by the cover body 401 and the connecting cover 4012 to prevent the dust from being blown away by the wind during the stone cleaning process, resulting in unorganized dust emissions. The cover body 401 and the connecting cover 4012 can reduce the pollution of the dust in the stone to the surrounding environment, and improve the environmental protection level during the stone processing process.

[0044] A water pump is provided on the spray pipe 302, and the water reservoir 2 is connected to the sedimentation tank through a pipeline. The clean water area of ​​the sedimentation tank is fixedly connected to the water inlet end of the spray pipe 302. Driven by the water pump, the clean water in the water reservoir 2 is discharged into the sedimentation tank through the pipeline. After flocculation and sedimentation in the sedimentation tank, the clean water area in the sedimentation tank is re-transported to the spray pipe 302 under the drive of the water pump, and used as spray water to spray and clean the gravel.

[0045] A guide plate 6 is provided on the top of the support platform 1. The guide plate 6 is arranged obliquely. The top of the guide plate 6 corresponds to the discharge port 4013. The stones guided from the supporting plate 3 are transferred to other equipment through the guide plate 6.

[0046] A discharge port 4013 is provided at one end of the cover body 401 away from the feed door 4011, and a baffle 4014 is movably hinged at one end of the supporting plate 3 away from the feed door 4011. The baffle 4014 corresponds to the discharge port 4013. During the stone cleaning process, the baffle 4014 closes the discharge port 4013 to prevent dust from flowing out through the discharge port 4013. An electric-controlled telescopic rod 4015 is provided at one end of the supporting plate 3 away from the feed door 4011. The telescopic end of the electric-controlled telescopic rod 4015 is slidably connected to the baffle 4014. After the stone is cleaned, the electric-controlled telescopic rod 4015 controls the baffle 4014 to open the discharge port 4013, so that the stones on the supporting plate 3 are discharged outward through the discharge port 4013.

[0047] During use, the feeding pipe of the external conveying equipment is fixedly docked with the connecting head of the connecting cover 4012, and a batch of stones to be cleaned of a certain weight are conveyed from the stone pile to the supporting plate 3 by the input end of the external conveying equipment. Parts of the feeding pipe and the suction pipe 403 are flexible tubes, which do not interfere with the flipping movement of the supporting plate 3. After the stones are conveyed, the cylinder 104 continues to extend, and the supporting plate 3 flips upward with the rotating shaft 103 as the center point, so that the supporting plate 3 gradually tilts and reaches the preset position. At this time, the natural gravity of the supporting plate 3 after tilting is utilized, and at the same time, the cylinder 104 repeatedly expands and contracts over a short distance and at a high frequency, generating vibration between the cylinder 104 and the stones, prompting the stones to move toward the supporting plate 3 near the discharge port 4013, so that the stones are more evenly distributed on the supporting plate 3. During this process, the electrically controlled telescopic rod 4015 remains extended, and the baffle 4014 is close to the supporting plate 3. The discharge port 4013 prevents the stones from sliding down prematurely. After the preset time is reached, the cylinder 104 stops the short-distance high-frequency repeated extension and contraction, and then the support plate 3 is turned downward with the rotating shaft 103 as the center point through the continuous contraction of the cylinder 104, and the support plate 3 is reset to remain horizontal. At the same time, the suction fan on the suction pipe 403 is started, and the air in the cover body 401 is discharged outward through the suction pipe 403 to form a negative pressure in the cover body 401. The air outside the cover body 401 is replenished into the cover body 401 through the leakage hole 301. While the air in the cover body 401 is continuously discharged outward through the suction pipe 403, the dust in the cover body 401 is discharged from the cover body 401 together with the air flow, reducing the dust content in the cover body 401. By reducing the dust content in the cover body 401, the cleaning burden of the subsequent spray pipeline 302 on the pollutants on the surface of the stones is further reduced.

[0048] In the initial state, the electric telescopic rod 503 is in a retracted state, the rotating plate 501 is in a vertical state, and the top of the rotating plate 501 is close to the sprinkler head 3021. The top of the rotating plate 501 blocks the sprinkler head 3021, so that the water sprayed downward from the sprinkler head 3021 forms a uniform water curtain after impacting the top of the rotating plate 501. The water curtain covers the supporting plate 3 as a whole, first fully wetting the surface of the stone. During the continuous spraying of the water body, the dust on the surface of the stone is washed away and flows into the water reservoir 2 through the leakage hole 301 with the water flow. After the preset spraying time is reached, the valve on the spray pipe 302 is closed, and the electric telescopic rod 4015 is retracted, driving the baffle 4014 to flip around the hinge point of the baffle 4014 and the supporting plate 3, so that the baffle 4014 and the guide plate 6 are parallel to each other. The discharge port 4013 is opened, and the stones move along the supporting plate 3 toward the discharge port 4013 under the action of gravity. During this process, the rotating plate 501 is driven to rotate by the motor 502, and at the same time, the telescopic end of the electric telescopic rod 503 extends and drives the motor 502 and the rotating plate 501 to move downward, so that the outer side of the rotating plate 501 is close to the lower surface of the internal trough of the supporting plate 3. In the rotating state, the rotating plate 501 forms a scraping effect on the stones, thereby increasing the falling speed of the stones from the supporting plate 3. The stones discharged from the discharge port 4013 are transferred to other equipment through the guide plate 6 for subsequent processing. In this way, the cleaning and transportation of this batch of stones are completed, the subsequent processing efficiency is improved, and the dust pollution during the subsequent stone processing is reduced. Then the various components are reset, and the device enters the preparation state for cleaning the next batch of stones.

[0049] In summary, by evenly spreading the stones on the support plate 3 and combining the comprehensive coverage and cleaning of the stones with a spray water curtain, the cleaning efficiency of the dust on the stone surface is improved, and an automated and continuous stone cleaning process is achieved.

[0050] Example 2: Please refer to Figures 1 to 6 As shown, in actual use, due to the different thicknesses of dust covering the stones, after the stones are laid flat on the supporting plate 3, the dust in the dust-rich area of ​​the stone pile is difficult to escape upward from the stone pile within a preset time. In particular, the dust in the lower half of the stone pile is more difficult to be washed away by the water curtain, resulting in a large amount of dust remaining inside the stone pile and low cleaning efficiency of the water body on the stone pile as a whole. In this regard, the following embodiment 2 is provided to solve the above problem:

[0051] An outer frame 404 extending toward the supporting plate 3 is provided at the bottom of the suction hood 402, and a connecting plate 405 is provided on the inner side of the outer frame 404. There are multiple connecting plates 405, which divide the outer frame 404 into multiple troughs. A dust concentration sensor is provided inside each trough. When the suction pipe 403 draws the airflow in the hood 401 upward, the dust concentration sensors in the multiple troughs correspondingly detect the dust content in the stones at different positions on the supporting plate 3.

[0052] When the stones are laid flat on the supporting plate 3 and the supporting plate 3 is kept horizontal under the action of the contraction of the cylinder 104, the cylinder 104 is started again and repeatedly extends and contracts over a short distance at a high frequency, so that the stone pile on the supporting plate 3 repeatedly collides with the supporting plate 3 and generates vibration. Under the action of the suction pipe 403 to discharge the gas in the cover 401 to the outside, the gas passes through the leakage hole 301 upward through the gaps between the stones, carrying the dust between the stones to move upward and pass through the connecting plate 405. In this process, the dust concentration sensor detects the dust concentration in the passing gas, and determines the area with higher dust content in the stone pile on the supporting plate 3 based on the dust concentration value in the gas detected by the dust concentration sensor. Then, the two adjacent motors 502 corresponding to the area are started, and the two motors 502 drive the rotating plate 501 to rotate, so that the bottom ends of the two adjacent rotating plates 501 are close to each other. At the same time, driven by the electric telescopic rod 503, the rotating plates The bottom end of 501 is inserted into the stone pile and close to the supporting plate 3. At this time, the stone pile with high dust content is gathered between the two rotating plates 501. Under the repeated collision and vibration between the supporting plate 3 and the stone pile, a certain gap is maintained between the stones. Since the bottoms of the two rotating plates 501 are closer, when the suction pipe 403 draws the gas in the cover body 401 outward, the two rotating plates 501 make the upward airflow more concentrated when the airflow passes through the stone pile with high dust content, so that the suction pipe 403 can attract more dust to move upward per unit time, thereby improving the upward movement efficiency of the dust in the stone pile with high dust content. The dust concentration sensor continuously detects the dust concentration in the upward gas, and finally makes the dust concentration in the stone pile on the supporting plate 3 basically flat and lower than the preset threshold value in the dust concentration sensor. Then the spray pipeline 302 is started again, and the stones are sprayed and cleaned through the spray head 3021.

[0053] To sum up, based on the concentration of dust overflowing upward from the gravel pile on the supporting plate 3, the area with high dust content in the gravel pile on the supporting plate 3 is determined, and by adjusting the angle of the rotating plate 501 corresponding to the area, combined with the vibration effect between the supporting plate 3 and the gravel pile and the outward suction effect of the suction pipe 403, the efficiency of removing dust from the high dust content area in the gravel pile is accelerated. By reducing the dust content in the gravel pile, the overall flushing and cleaning efficiency of the subsequent spraying water on the gravel pile is improved.

[0054] Furthermore, in order to improve the spray cleaning efficiency of the spray head 3021 on the stones, after the spray pipeline 302 is started, the rotating plate 501 is driven to rotate by the motor 502, and the rotating plate 501 is used as a water guide plate when the spray head 3021 sprays downward. Therefore, in the process of the motor 502 driving the rotating plate 501 to adjust the angle, the downward spraying direction of the spray head 3021 is changed synchronously, and the rotating plate 501 is used to guide the direction of the spray water, so that the spray water can be targeted and flushed according to the stone pile area with high dust content.

[0055] However, when the thickness of the stones carried on the supporting plate 3 is relatively thick, the stones on the upper layer can be quickly cleaned by the spray water, and the stones on the lower layer lack the opportunity to directly contact with the spray water. Therefore, the following improvements are made:

[0056] The rotating seat 102 is fixedly connected to the water tank 2 through the connecting frame 101, and the rotating seat 102 is slidably connected to the connecting frame 101. An electromagnetic lock is provided at the connection between the bottom of the rotating seat 102 and the connecting frame 101. When the electromagnetic lock is powered on, the rotating seat 102 can slide on the connecting frame 101. When the electromagnetic lock is powered off, the rotating seat 102 is locked and fixed to the connecting frame 101. Filters are provided at the top and bottom ends of the rotating plate 501 respectively. An electromagnetic latch is provided at the connection between the rotating shaft 103 and the rotating seat 102 for locking and fixing the rotating shaft 103 and the rotating seat 102.

[0057] When in use, when the supporting plate 3 carries thicker stones, the extension of the telescopic end of the electric telescopic rod 503 is used to drive the rotating plate 501 and the motor 502 to approach the center line position of the internal groove of the supporting plate 3, that is, the boundary position of the upper and lower stones. At this time, the supporting plate 3 is in a horizontal state, and the electromagnetic latch at the connection between the rotating shaft 103 and the rotating seat 102 is powered off, so that the rotating shaft 103 and the rotating seat 102 are locked. At the same time, the electromagnetic lock between the rotating seat 102 and the connecting frame 101 is powered on and the cylinder 104 starts to move. The telescopic end of the cylinder 104 is driven and controlled to extend and retract over a short distance at a high frequency, so that the rotating seat 102 moves horizontally repeatedly on the connecting frame 101. This process causes the stones on the supporting plate 3 to produce horizontal displacement relative to the supporting plate due to the inertial force, prompting the upper stones to transfer to the filter screen on the rotating plate 501. Subsequently, the rotating plate 501 is driven to flip by controlling the motor 502, and the stones on the filter screen are driven to flip, thereby exposing the lower stones, thereby improving the flushing efficiency of the lower stones and ensuring uniform cleaning of the entire stone layer.

[0058] Example 3: Please refer to Figures 1 to 6As shown, although the vibration between the supporting plate 3 and the stone pile can make the stones evenly spread on the supporting plate 3, and the stones can be evenly washed by the spray head 3021 in cooperation with the rotating plate 501, in actual use, dirt such as plate lumps are still attached to the stones. This part of the dirt cannot be quickly separated from the stones under the influence of vibration and airflow, and the spray head 3021 is difficult to quickly and thoroughly clean the dirt on the stones. As a result, during the subsequent transportation and processing of the stones, the dirt falls off the stones, causing pollution to the environment. In this regard, the following embodiment 3 is proposed to solve the above problems:

[0059] A pressure sensor and a turbidity sensor are provided at the inner bottom of the supporting plate 3. The stones are evenly spread on the supporting plate 3. Dirt such as lumps are tightly attached to the surface of the stones or accumulated in the gaps between the stones. The areas with more dirt in the stone pile are heavier. In this regard, the weight of different areas of the stone pile is detected by the pressure sensor on the supporting plate 3. For the heavier areas in the stone pile, the two adjacent motors 502 at the corresponding positions are started, and the two motors 502 respectively drive the bottom ends of the two rotating plates 501 to move closer to each other, so that the two rotating plates A bucket-like structure is formed between 501 and the supporting plate 3, that is, the distance between the top ends of the two rotating plates 501 is greater than the distance between the bottom ends of the two rotating plates 501. At the same time, the electric telescopic rod 503 extends and drives the rotating plate 501 to approach the supporting plate 3. The spray pipe 302 remains in the started state. The spray water sprayed by the two rows of spray heads 3021 is guided by the rotating plate 501 and gathers toward the inner side of the two rotating plates 501. Since the bottom area of ​​the two rotating plates 501 is narrower than the top area, and the two adjacent rows of spray pipes 302 spray into this area, the water sprayed by the two rows of spray heads 3021 is concentrated toward the inner side of the two rotating plates 501. The speed of water gathering between the two rotating plates 501 is greater than the speed of water falling through the leaking hole 301, so that the water quickly gathers between the two rotating plates 501, forming a local high water level between the two rotating plates 501. Due to the rapid gathering of the spray water in this area, the liquid level of the water between the two rotating plates 501 is kept above the upper surface of the stone pile, so that the dirt such as the plate lumps on the stones in this area are quickly and fully contacted with the water. In this process, the two motors 502 respectively drive the two rotating plates 501 to swing back and forth, so that the two rotating plates 501 The bottom end of the moving plate 501 repeatedly disturbs the stones and water between the two rotating plates 501, so that the stones keep colliding with each other, thereby increasing the speed of separation of the compacted materials on the stones. The cylinder 104 is started synchronously, and the short-distance and high-frequency extension and contraction of the cylinder 104 drives the supporting plate 3 to move up and down with the rotating shaft 103 as the center point, thereby improving the fluidity of the water between the two rotating plates 501 and preventing the stones from gathering locally under the drive of the rotating plates 501 during the swinging process, thereby achieving efficient and sufficient mixing of the stones and the water.

[0060] Among them, the turbidity sensor at the inner bottom of the supporting plate 3 is used to detect the turbidity of the water in the inner bottom area of ​​the supporting plate 3 during the stone spray cleaning process. When the turbidity sensor detects that the turbidity value of the water is lower than the preset value, it indicates that the stone cleaning process is completed. The supporting plate 3 is flipped upward by extending the cylinder 104, and the baffle 4014 is removed by the electric-controlled telescopic rod 4015, so that the cleaned stones slide to the discharge port 4013 and are transferred through the guide plate 6.

[0061] To sum up, through the pressure sensor and the turbidity sensor, the area with more dirt in the gravel pile can be accurately detected, and the rotating plate 501 at the corresponding position is started to clean the area in a targeted manner, saving energy consumption. At the same time, the rotating plate 501 and the supporting plate 3 disturb the gravel and water body, ensuring that the gravel and water are efficiently mixed, achieving rapid and thorough cleaning of the gravel, and effectively avoiding the pollution to the environment caused by the falling of dirt.

[0062] Example 4: The present invention also provides a method for using the dust suppression and cleaning device of a gravel processing plant as described above, comprising the following steps:

[0063] S1. First, the stones to be cleaned are transported in batches from the feed gate 4011 to the supporting plate 3 through an external conveying device.

[0064] S2. The cylinder 104 is extended to increase the tilt angle of the support plate 3. With the influence of natural gravity on the stones, the vibration generated between the cylinder 104 and the stones during the repeated contraction and extension process causes the stones to move to the other side of the support plate 3.

[0065] S3. The dust generated during the movement of the stones is carried by the gas and discharged synchronously as the air suction hood 402 continuously draws the gas outward.

[0066] S4. Then, the switch of the spraying pipeline 302 is started again to clean and remove the pollutants on the surface of the stone through the spraying pipeline 302.

[0067] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's description and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
