Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of screening devices, and more particularly, to an aggregate screening device with an adjustable internal screening structure. Background Art

[0002] With the acceleration of the urbanization process, the annual output of construction waste has accounted for more than 30% of the global solid waste. The traditional landfill treatment method has been gradually phased out due to environmental pollution and land resource waste, and resource utilization has become the mainstream trend. The recycling of aggregates needs to be screened and graded to meet the particle size and cleanliness requirements of recycled building materials.

[0003] The patent with the patent publication number CN219073511U relates to an aggregate screening device for construction waste, including a base. Support columns are symmetrically arranged at the top of the base. A guide rod is arranged between the support columns. An installation plate is arranged at the top of the guide rod. A winding gear is arranged at the top of the installation plate. A traction rope is arranged outside the winding gear. One end of the traction rope is provided with a positioning block. Positioning frames are arranged at both ends of the positioning block. Rollers are symmetrically arranged inside the positioning frames. An aggregate bin is arranged on one side of the positioning frame. A cover plate is arranged on one side of the aggregate bin. By using the structure of the aggregate bin, winding gear, positioning block, positioning frame, and traction rope, the problem that the aggregate bin is located at the top of the device due to the height difference design for filtration in the existing aggregate screening device, which makes it inconvenient to load waste materials, is solved.

[0004] In the above patent, by using the structure of the aggregate bin, winding gear, positioning block, positioning frame, and traction rope, the problem that the aggregate bin is located at the top of the device due to the height difference design for filtration in the existing aggregate screening device, which makes it inconvenient to load waste materials, is solved. However, during the stirring and separation process, it is difficult to prevent the filter screen from being blocked when screening stones and soil, resulting in a decrease in the screening efficiency. At the same time, it is difficult to control and adjust the feeding of aggregates, resulting in a decrease in the stirring effect and screening effect, and further affecting the screening efficiency. Summary of the Invention

[0005] To overcome the above defects, embodiments of the present disclosure provide an aggregate screening device with an adjustable internal screening structure, which solves the technical problem of difficult control and adjustment of the feeding of aggregates in the prior art.

[0006] According to one aspect, at least one embodiment of the present disclosure provides an aggregate screening device with adjustable internal screening structure, including a filter tank body and a discharging mechanism. The top of the filter tank body is fixedly penetrated with a feed inlet, and the bottom of the filter tank body is fixedly installed with an earth outlet. It also includes a filtering device, an anti-blocking device, and a dust reduction device. Among them, the filtering device includes a motor, a first stirring ring, a second stirring ring, an inclined block, a U-shaped rod, a filter screen, a T-shaped rod, and a transmission shaft. The motor is fixedly installed on the top of the filter tank body, the transmission shaft is fixedly installed at the output end of the motor, the first stirring ring is fixedly installed on the circumferential surface of the transmission shaft, the second stirring ring is fixedly installed on the circumferential surface of the transmission shaft, the inclined block is fixedly installed on the inner wall of the filter tank body, the U-shaped rod is slidably installed on the inner wall of the filter tank body, the filter screen is slidably installed on the inner wall of the filter tank body, one end of the T-shaped rod is fixedly installed at the bottom of the first stirring ring, and the other end of the T-shaped rod is fixedly installed at the top of the second stirring ring. The rotation of the first stirring ring drives the T-shaped rod to rotate. When the T-shaped rod rotates and contacts the inclined block, the inclined block squeezes the T-shaped rod, and the T-shaped rod moves upward under the squeezing force. The upward movement of the T-shaped rod drives the first stirring ring and the second stirring ring to move upward.

[0007] For example, in an aggregate screening device with an adjustable internal screening structure provided by at least one embodiment of the present disclosure, the filtering device further includes a push rod, a telescopic plate, and a rotating ring. The telescopic plate is fixedly installed at the top of the inner wall of the filter tank body. One end of the push rod is rotatably installed at the bottom of the telescopic plate, and the other end of the push rod is rotatably installed inside the U-shaped rod. One end of the rotating ring is fixedly installed at the bottom of the second stirring ring, and the other end of the rotating ring is rotatably installed on the top of the filter screen. The upward movement of the first stirring ring squeezes the U-shaped rod to move upward. The upward movement of the U-shaped rod drives the push rod to move upward. The upward movement of the push rod pushes the telescopic plate to move in the direction close to the transmission shaft to control and adjust the amount of aggregate entering. At the same time, the second stirring ring moves upward, driving the rotating ring to move upward. The upward movement of the rotating ring drives the filter screen to move upward.

[0008] The U-shaped rod contacts the first stirring ring. A square hole is formed on the circumferential surface of the filter tank body, and the discharging mechanism is connected to the square hole, which is convenient for the first stirring ring to squeeze the U-shaped rod, thereby controlling and adjusting the feeding of the aggregate.

[0009] According to another aspect, at least one embodiment of the present disclosure further provides an aggregate screening device with an adjustable internal screening structure. The anti-blocking device includes a first baffle, a scraping rod, a fixing block, an elastic telescopic rod, a U-shaped pushing plate, and a connecting plate. The scraping rod is fixedly installed on the circumferential surface of the rotating ring. The fixing block is fixedly installed on the top of the filter net. The elastic telescopic rod is fixedly installed on the side of the fixing block close to the square hole. The connecting plate is fixedly installed on the inner wall of the square hole. The first baffle is fixedly installed on the top of the connecting plate. The U-shaped pushing plate is slidably installed on the top of the connecting plate. When the rotating ring rotates, it drives the scraping rod to rotate, scraping the surface of the filter net. When the filter net moves upward, it drives the fixing block to move upward. The upward movement of the fixing block drives the elastic telescopic rod to move upward. The elastic telescopic rod continues to move upward and disengages from the filter tank body. The output end of the elastic telescopic rod pops out in the direction close to the U-shaped pushing plate through elastic force.

[0010] The anti-blocking device further includes a first square block, a circular shaft, and a knocking rod. The first square block is fixedly installed on the inner wall of the filter tank body. The circular shaft is fixedly installed on the side of the first square block close to the second stirring ring. The knocking rod is rotatably installed on the circumferential surface of the circular shaft. At the same time, when the scraping rod rotates and contacts the knocking rod and squeezes the knocking rod, the knocking rod moves upward under the extrusion force. At the same time, the scraping rod continues to rotate and disengages from the knocking rod. The knocking rod moves downward under its own gravity, knocking and vibrating the surface of the filter net.

[0011] A first spring is arranged between the first baffle and the U-shaped pushing plate. The connecting plate contacts the discharging mechanism. The lower part of the output end of the elastic telescopic rod is a slope, which facilitates the reset of the U-shaped pushing plate and the elastic telescopic rod.

[0012] For example, in an aggregate screening device with an adjustable internal screening structure provided by at least one embodiment of the present disclosure, the dust reduction device includes a first support column, a second square block, a second baffle, a sliding plate, a second support column, a water spraying pipe, a gear, and a rack. The first support column is fixedly installed on the top of the discharging mechanism. The second support column is fixedly installed on the top of the discharging mechanism. The second baffle is fixedly installed on the top of the discharging mechanism. The sliding plate is slidably installed on the side of the second support column close to the filter tank body. The second square block is fixedly installed on the side of the sliding plate away from the second baffle. One end of the water spraying pipe is rotatably installed on the side of the second support column close to the second baffle. The other end of the water spraying pipe is rotatably installed on the side of the first support column close to the second baffle. The gear is fixedly installed on the circumferential surface of the water spraying pipe. The rack is fixedly installed on the side of the sliding plate close to the water spraying pipe. The rack meshes with the gear. When the U-shaped pushing plate moves away from the filter tank body and contacts and squeezes the sliding plate, the sliding plate moves upward under the extrusion force. The upward movement of the sliding plate drives the rack to move upward. The upward movement of the rack drives the gear to rotate. The rotation of the gear drives the water spraying pipe to rotate, spraying water on the screened aggregates at different angles.

[0013] A second spring is provided between the second square block and the discharging mechanism. The side of the sliding plate close to the U-shaped push plate is an inclined surface, which facilitates the reset of the sliding plate and enables the sliding plate to be better subjected to the extrusion force and move upward.

[0014] The beneficial effects of the embodiments of the present disclosure are as follows: In the present disclosure, when it is necessary to screen the aggregate, the motor is started to drive the transmission shaft to rotate. The rotation of the transmission shaft drives the first stirring ring and the second stirring ring to rotate, stirring the aggregate to make the separation effect better. At the same time, the T-shaped rod contacts the inclined surface block, and the inclined surface block extrudes the T-shaped rod, causing the T-shaped rod to move upward. As a result, the first stirring ring and the second stirring ring move upward, better stirring the aggregate and improving the separation effect. The upward movement of the second stirring ring drives the filter net upward, preventing the filter net from being blocked during the process of separating stones and soil, thereby reducing the separation effect. At the same time, the upward movement of the first stirring ring blocks the feeding port, controlling and adjusting the amount of aggregate entering, and preventing too much aggregate from entering and affecting the separation effect.

[0015] In the present disclosure, the rotation of the second stirring ring drives the scraping rod to rotate, preventing the surface of the filter net from being blocked and reducing the separation efficiency. At the same time, when the scraping rod rotates and contacts and squeezes the knocking rod, the knocking rod moves upward. When the scraping rod disengages from the knocking rod, the knocking rod moves downward by its own gravity, knocking and vibrating the filter net to better prevent filter blockage and thus reduce the separation efficiency.

[0016] In the present disclosure, the upward movement of the filter net drives the fixed block and the elastic telescopic rod upward. When the elastic telescopic rod disengages from the inner wall of the filter tank body, it pops out in the direction close to the U-shaped push plate by the elastic force, dredging the square hole outlet and preventing the square hole from being blocked, resulting in the aggregate not being able to go out. At the same time, the elastic telescopic rod pops out and contacts and squeezes the U-shaped push plate, moving the U-shaped push plate to the side away from the filter tank body, pushing the separated aggregate, and better preventing the square hole from being blocked, resulting in the aggregate not being able to go out.

[0017] In the present disclosure, the aggregate is dusted by spraying water through the water spray pipe, preventing the dust from being large during the transmission of the aggregate and affecting the environment. At the same time, when the U-shaped push plate moves, it contacts and squeezes the sliding plate, and the sliding plate is subjected to the extrusion force and moves upward, driving the gear to rotate, thereby adjusting the direction of the water spray pipe and spraying water on the aggregate at different angles, better dusting the aggregate, and preventing the dust from being large during the transmission of the aggregate, affecting the environment and harming the health of the staff.

[0026] Such as Figures 1 to 11As shown, it shows an aggregate screening device with adjustable internal screening structure in an embodiment of the present disclosure, including a filter tank body 1 and a discharge mechanism 7. The top of the filter tank body 1 is fixedly penetrated with a feed inlet 2, and the bottom of the filter tank body 1 is fixedly installed with an earth outlet 3. It also includes a filtering device; wherein, the filtering device includes a motor 41, a first stirring ring 42, a second stirring ring 43, an inclined block 44, a U-shaped rod 45, a filter screen 46, a T-shaped rod 47 and a transmission shaft 410. The motor 41 is fixedly installed on the top of the filter tank body 1, the transmission shaft 410 is fixedly installed at the output end of the motor 41, the first stirring ring 42 is fixedly installed on the circumferential surface of the transmission shaft 410, the second stirring ring 43 is fixedly installed on the circumferential surface of the transmission shaft 410, the inclined block 44 is fixedly installed on the inner wall of the filter tank body 1, the U-shaped rod 45 is slidably installed on the inner wall of the filter tank body 1, the filter screen 46 is slidably installed on the inner wall of the filter tank body 1, one end of the T-shaped rod 47 is fixedly installed at the bottom of the first stirring ring 42, and the other end of the T-shaped rod 47 is fixedly installed at the top of the second stirring ring 43. The aggregate is filtered and separated by the first stirring ring 42, the second stirring ring 43 and the filter screen 46. At the same time, the reciprocating movement of the first stirring ring 42, the second stirring ring 43 and the filter screen 46 is driven by the movement of the T-shaped rod 47, so that the effect of aggregate separation is better, and at the same time, the blockage of the filter screen 46 is prevented.

[0027] In some examples, the filtering device further includes a push rod 48, a telescopic plate 49 and a rotating ring 411. The telescopic plate 49 is fixedly installed at the top of the inner wall of the filter tank body 1. One end of the push rod 48 is rotatably installed at the bottom of the telescopic plate 49, and the other end of the push rod 48 is rotatably installed inside the U-shaped rod 45. One end of the rotating ring 411 is fixedly installed at the bottom of the second stirring ring 43, and the other end of the rotating ring 411 is rotatably installed at the top of the filter screen 46. The feeding speed of the aggregate is controlled and adjusted by the expansion and contraction of the telescopic plate 49 to prevent too much aggregate from entering, which affects the stirring effect and thus the separation effect.

[0028] The U-shaped rod 45 contacts the first stirring ring 42. A square hole is formed on the circumferential surface of the filter tank body 1, and the discharge mechanism 7 is connected to the square hole, which is convenient for the first stirring ring 42 to squeeze the U-shaped rod 45, so as to control and adjust the feeding of the aggregate and facilitate the transportation of the aggregate.

[0029] For example, as Figures 1 to 11As shown, when it is necessary to screen the aggregate, the aggregate enters the interior of the filter tank body 1 through the feed port 2. At the same time, the motor 41 is started. The start of the motor 41 drives the transmission shaft 410 to rotate. The rotation of the transmission shaft 410 drives the first stirring ring 42 and the second stirring ring 43 to rotate, stirring the aggregate. The rotation of the first stirring ring 42 drives the T-shaped rod 47 to rotate. The rotation of the T-shaped rod 47 contacts the inclined block 44. The inclined block 44 exerts pressure on the T-shaped rod 47. The T-shaped rod 47 moves upward under the extrusion force. The upward movement of the T-shaped rod 47 drives the first stirring ring 42 and the second stirring ring 43 to move upward. The upward movement of the first stirring ring 42 squeezes the U-shaped rod 45 to move upward. The upward movement of the U-shaped rod 45 drives the push rod 48 to move upward. The upward movement of the push rod 48 pushes the telescopic plate 49 to move in the direction close to the transmission shaft 410, controlling and adjusting the amount of aggregate. At the same time, the second stirring ring 43 moves upward, driving the rotating ring 411 to move upward. The upward movement of the rotating ring 411 drives the filter screen 46 to move upward, preventing the filter screen 46 from being blocked. The filter screen 46 screens the aggregate. After screening, the aggregate is transported through the discharge mechanism 7. At the same time, the filter screen 46 moves upward, sprinkling the screened aggregate, so that the aggregate can be better transported out through the discharge mechanism 7.

[0030] As Figures 1 to 11 shown, it shows that in another embodiment of the present disclosure, it further includes an anti-blocking device and a dust reduction device. The anti-blocking device includes a first baffle 51, a scraping rod 52, a fixing block 53, an elastic telescopic rod 54, a U-shaped push plate 58 and a connecting plate 59. The scraping rod 52 is fixedly installed on the circumferential surface of the rotating ring 411. The fixing block 53 is fixedly installed on the top of the filter screen 46. The elastic telescopic rod 54 is fixedly installed on one side of the fixing block 53 close to the square hole. The connecting plate 59 is fixedly installed on the inner wall of the square hole. The first baffle 51 is fixedly installed on the top of the connecting plate 59. The U-shaped push plate 58 is slidably installed on the top of the connecting plate 59. The surface of the filter screen 46 is scraped by the scraping rod 52 to prevent the filter screen 46 from being blocked and dredge the square hole, preventing the screened aggregate from accumulating in the square hole, facilitating the transportation of the aggregate and improving work efficiency. In some examples, the anti-blocking device further includes a first square block 55, a circular shaft 56 and a knocking rod 57. The first square block 55 is fixedly installed on the inner wall of the filter tank body 1. The circular shaft 56 is fixedly installed on one side of the first square block 55 close to the second stirring ring 43. The knocking rod 57 is rotatably installed on the circumferential surface of the circular shaft 56, knocking on the filter screen 46 to better prevent the filter screen 46 from being blocked during the screening and separation process and reducing work efficiency.

[0031] A first spring is arranged between the first baffle 51 and the U-shaped push plate 58. The connecting plate 59 contacts the discharge mechanism 7. The lower end of the output end of the elastic telescopic rod 54 is an inclined surface, facilitating the reset of the U-shaped push plate 58 and the elastic telescopic rod 54.

[0032] The dust-removing device includes a first support column 61, a second square block 62, a second baffle 63, a sliding plate 64, a second support column 65, a water spray pipe 66, a gear 67 and a rack 68. The first support column 61 is fixedly installed on the top of the discharging mechanism 7, the second support column 65 is fixedly installed on the top of the discharging mechanism 7, the second baffle 63 is fixedly installed on the top of the discharging mechanism 7, the sliding plate 64 is slidably installed on the side of the second support column 65 close to the filter tank body 1, the second square block 62 is fixedly installed on the side of the sliding plate 64 away from the second baffle 63, one end of the water spray pipe 66 is rotatably installed on the side of the second support column 65 close to the second baffle 63, the other end of the water spray pipe 66 is rotatably installed on the side of the first support column 61 close to the second baffle 63, the gear 67 is fixedly installed on the circumferential surface of the water spray pipe 66, the rack 68 is fixedly installed on the side of the sliding plate 64 close to the water spray pipe 66, the rack 68 meshes with the gear 67, and the rotation of the gear 67 drives the water spray pipe 66 to rotate, spraying water on the screened aggregate at different angles to prevent the aggregate from generating a large amount of dust during transportation, affecting the ecological environment and endangering the health of the staff.

[0033] A second spring is arranged between the second square block 62 and the discharging mechanism 7. The side of the sliding plate 64 close to the U-shaped push plate 58 is an inclined surface, which facilitates the reset of the sliding plate 64 and enables the sliding plate 64 to be better subjected to the extrusion force and move upward.

[0034] For example, as Figures 1 to 11 shown, when the second stirring ring 43 rotates, it drives the rotating ring 411 to rotate. The rotation of the rotating ring 411 drives the scraping rod 52 to rotate, scraping the surface of the filter net 46 to prevent the filter net 46 from being blocked. At the same time, when the scraping rod 52 rotates, it contacts the knocking rod 57 and squeezes the knocking rod 57. The knocking rod 57 moves upward under the extrusion force. At the same time, the scraping rod 52 continues to rotate and disengages from the knocking rod 57. The knocking rod 57 moves downward by its own gravity, knocking and vibrating the surface of the filter net 46 to better prevent the filter net 46 from being blocked. At the same time, when the filter net 46 moves upward, it drives the fixed block 53 to move upward. The upward movement of the fixed block 53 drives the elastic telescopic rod 54 to move upward. The elastic telescopic rod 54 continues to move upward and disengages from the filter tank body 1. The output end of the elastic telescopic rod 54 pops out towards the direction close to the U-shaped push plate 58 by the elastic force. At the same time, the output end of the elastic telescopic rod 54 pops out towards the direction close to the U-shaped push plate 58 and contacts the U-shaped push plate 58 and squeezes the U-shaped push plate 58. The U-shaped push plate 58 moves away from the filter tank body 1 under the extrusion force, dredging and pushing the aggregate to prevent the aggregate from accumulating in the square holes and causing the aggregate to be unable to come out.

[0035] During the discharging process, the water spraying pipe 66 sprays water on the aggregate to reduce dust and prevent excessive dust during transportation from affecting the environment. At the same time, when the U-shaped push plate 58 moves away from the filter tank body 1, it contacts and squeezes the sliding plate 64. The sliding plate 64 moves upward under the extrusion force. The upward movement of the sliding plate 64 drives the rack 68 to move upward. The upward movement of the rack 68 drives the gear 67 to rotate. The rotation of the gear 67 drives the water spraying pipe 66 to rotate, spraying water on the screened aggregate at different angles, better reducing dust on the aggregate, and preventing excessive dust during the transportation of the aggregate from affecting the ecological environment and endangering the health of the staff.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and not to limit them. Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered within the scope of the claims of the present disclosure.
