[0002] A concrete drum screen is a screening device designed specifically for the construction industry, mainly used for precisely separating different particle size particles in concrete aggregates to ensure that the aggregate quality meets high standard requirements. Its core structure consists of a motor, a speed reducer, an inclined drum device, and a sealing cover. The rotation of the drum drives the material to flip and roll. Fine particles (such as sand) fall into the lower collection port through the screen mesh, while coarse particles (such as stones) are discharged from the end. The device adopts a high-strength wear-resistant screen and anti-blocking design (such as a comb-shaped screen cleaning mechanism), which can effectively handle sticky and wet materials, avoid screen hole blockage, and at the same time has good sealing to reduce dust pollution. In concrete production, it can strictly screen out aggregates within a specific particle size range, removing oversized or undersized particles, thus ensuring the strength of concrete and construction stability, and having the characteristics of high-efficiency screening (large processing capacity, high classification accuracy) and energy conservation and environmental protection.

During the export process, there are problems that particles are easily adhered to or block the discharge ports, and the particulate matter is easily piled up together to block the discharge ports. Therefore, a separation device for concrete recycling with a cleaning discharge port is proposed. Summary of the Invention

Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

[0031] In the related art, in the existing separation device, fine particles and coarse particles are respectively exported from two discharge ports during use. However, during the export process, there are easily problems such as particles adhering to the discharge port or blocking the discharge port, and the problem that the particulate matter is easily piled up together to block the discharge port. Therefore, a separation device for concrete recycling with a cleaning discharge port is proposed.
[0032] In order to solve the problems in the related art to a certain extent, the embodiments of the present application provide a separation device for concrete recycling. When the screened particles are respectively exported from two discharge ports, the rotation of a rotating shaft drives the rotation of a plurality of scraping plates. Since the particulate matter is doped with moisture and is easily adhered to the inner wall of the discharge port, at this time, the scraping plates rub the inner wall of the discharge port, enabling the material to be normally exported and reducing the situation of the discharge port being blocked.
[0033] The present application will be described below in conjunction with the accompanying drawings and with reference to specific embodiments:
[0034] In conjunction with Figures 1 - 5 , an embodiment of the present application provides a separation device for concrete recycling, including: a base 100, rotatably connected to a drum 110 thereon; a material guiding plate 120, fixed to the inner side wall of the base 100; a fine particle discharge port 130, fixed to one side of the base 100, and a coarse particle discharge port 140 is fixed to one side of the base 100; a scraping assembly 400, rotatably connected to the fine particle discharge port 130 or the coarse particle discharge port 140; a blowing assembly, arranged on the fine particle discharge port 130 or the coarse particle discharge port 140, and a transmission assembly is arranged on both the fine particle discharge port 130 and the coarse particle discharge port 140. When the blowing assembly rotates, it drives the transmission assembly to work, and the transmission assembly drives the scraping assembly 400 to rotate, and the scraping assembly 400 cleans the inner side wall of the fine particle discharge port 130 or the coarse particle discharge port 140.
[0035] Specifically, when recycling concrete, first, the concrete to be recycled is introduced into a material guiding box 200, the material guiding box 200 is connected to external water, and a water pump flushes the concrete mixture in the material guiding box 200 into the drum 110. The drum 110 is driven by a motor to rotate. During the rotation process, fine sand particles are discharged through the filter screen of the drum 110, and coarse sand particles are introduced onto the material guiding plate 120 by the rotation of the drum 110. The material guiding plate 120 guides the coarse sand particles to the coarse particle discharge port 140, and the fine sand particles in the base 100 are introduced to the fine particle discharge port 130 by the outer filter screen of the drum 110. Secondly, the fine sand particles are discharged from the fine particle discharge port 130, and the coarse sand particles are discharged from the coarse particle discharge port 140. During the discharging process, the blowing assembly is connected to a gas source, and the rotating jet of the blowing assembly dries the particulate matter, and the air pressure can be controlled to directly blow out some particulate matter, reducing the situation of particulate matter adhering to the inner wall. While drying with air blowing, the blowing assembly drives the transmission assembly to work, and the transmission assembly drives the scraping assembly 400 to rotate, and the scraping assembly 400 further scrapes and cleans the inner wall of the discharge port.
[0036] Furthermore, the material guiding box 200, also known as the feeding trough or the material guiding trough, at the front stage of the separation device plays the following core roles during the operation of the equipment:
[0037] The material guiding box 200 is the initial receiving device for residual concrete and cleaning water, and is responsible for introducing the sewage and concrete waste discharged from the mixer truck into the subsequent separation process. Its design usually has an inclined or trough-shaped structure to facilitate the natural flow of materials into the drum separator under the action of gravity or water flow impact.
[0038] In the material guiding box 200, the residual concrete is mixed with the recycled water injected under high pressure to form a more fluid slurry. This process accelerates the crushing of the concrete and the separation of sand and gravel by the impact of the water flow, providing a uniform material basis for subsequent screening.
[0039] The material guiding box 200 is usually designed with a high-pressure water spraying device or a stirring function such as a spiral blade to prevent large pieces of concrete from caking and blocking the equipment inlet. For example, in some models, the continuous water flow scouring and the periodic rotation of the agitator ensure that the material continuously and stably enters the separation system.
[0040] Some material guiding boxes 200 are equipped with valves such as material guiding valves and cleaning valves to adjust the flow rate of the material entering the separator and avoid overloading; the above description of the material guiding box 200 belongs to common knowledge and will not be elaborated here.
[0041] Furthermore, after the mixed material enters the drum, it rotates with the drum under the push of the spiral blade. Fine particles such as sand and slurry fall into the lower collecting device through the sieve holes on the surface of the drum, while coarse particles such as stones cannot pass through the sieve holes due to their large particle size and are discharged from the stone outlet along the advancing direction of the spiral blade. This principle belongs to the prior art and will not be elaborated here.
[0042] In some embodiments, the scraping assembly 400 includes a rotating shaft 410 rotatably connected to the inner side wall of the fine particle discharge port 130 or the coarse particle discharge port 140, and a plurality of scraping plates 420 are fixedly arranged on the outer side wall of the rotating shaft 410 in an array.
[0043] Specifically, when the rotating shaft 410 rotates under the action of the air blowing assembly, it drives the arrayed scraping plates 420 to perform a circumferential movement synchronously. The cutting edges of the scraping plates 420 continuously scrape along the inner side wall of the discharge port in a mechanical cleaning manner, forcibly peeling off the residual particulate matters (such as caked mortar or gravel) attached to the wall surface, thus effectively preventing the local blockage phenomenon caused by material accumulation, ensuring the continuous smoothness of the discharge channel, and at the same time reducing the frequency of manual cleaning. The two discharge ports are inclined and arranged on the base 100.
[0044] In some embodiments, the air blowing assembly includes an air pipe 300 inserted and fixed on the fine particle discharge port 130 or the coarse particle discharge port 140. The bottom end of the air pipe 300 is rotatably connected to a spray head 310, and the bottom end of the spray head 310 is rotatably connected to a plate body 320, and the plate body 320 is fixedly connected to the fine particle discharge port 130 or the coarse particle discharge port 140.
[0045] Specifically, an external air source is connected, and the gas with air pressure is introduced into the nozzle 310 through the air pipe 300. Due to the rotation of the nozzle 310, the gas is dispersed onto the particulate matter, thereby drying the particulate matter, and some of the particulate matter can be directly blown out, further reducing the situation of particulate matter adhering to the inner wall. A spiral blade is provided in the air pipe 300 to rotate the air flow, thereby rotating the nozzle 310.
[0046] In some embodiments, a bevel gear set is provided in the plate body 320.
[0047] Specifically, the bevel gear set mainly consists of two bevel gear assemblies. One bevel gear is connected to the bottom end of the nozzle 310. When the nozzle 310 rotates, the other bevel gear rotates, and at this time, the other bevel gear transmits the rotational force into the transmission assembly.
[0048] In some embodiments, the transmission assembly includes a first shaft body 510. The first shaft body 510 penetrates through the plate body 320 and is connected to the bevel gear set. A transmission box 500 is fixed to one side of the fine particle discharge port 130 or the coarse particle discharge port 140. A second shaft body 520 is rotatably connected to the inner side wall of the transmission box 500. A second bevel gear 521 is fixed to one end of the second shaft body 520, and a fourth bevel gear 523 is fixed to the outer side wall. An eighth bevel gear 411 that cooperates with the fourth bevel gear 523 is fixed to one end of the rotating shaft 410. A first bevel gear 511 that cooperates with the second bevel gear 521 is fixed to the outer side wall of the first shaft body 510.
[0049] Specifically, the force of the rotation of the nozzle 310 is transmitted to the first shaft body 510 by the bevel gear set. The first shaft body 510 drives the first bevel gear 511 to rotate. The first bevel gear 511 meshes with the second bevel gear 521, and the second bevel gear 521 drives the second shaft body 520 to rotate. The fourth bevel gear 523 on the outer side wall of the second shaft body 520 drives the eighth bevel gear 411 to rotate. At this time, the rotating shaft 410 drives the scraper 420 to start rotating, thereby realizing the rotation of the scraper 420 while jetting air.
[0050] In some embodiments, a material distribution assembly 600 is fixed to the bottom of the fine particle discharge port 130 or the coarse particle discharge port 140. When the transmission assembly works, it drives the material distribution assembly 600 to reciprocate.
[0051] Specifically, the reciprocating movement of the material distribution assembly 600 disperses the particulate matter accumulated at the discharge port, thereby reducing the situation of particulate matter accumulation.
[0052] In some embodiments, the material distribution assembly 600 includes a bearing seat 610. The bearing seat 610 is fixed to the bottom of the fine particle discharge port 130 or the coarse particle discharge port 140. A screw rod 620 is rotatably connected to the bearing seat 610. A material distribution plate 630 is threadedly connected to the outer side wall of the screw rod 620.
[0053] Specifically, the screw 620 is a bidirectional screw. The screw 620 rotates on the bearing block 610, and the screw 620 drives the material distribution plate 630 to reciprocate on the discharge port. The material distribution plate 630 disperses the particulate matter below the discharge port.
[0054] In some embodiments, a third shaft 530 is rotatably connected to the inner side wall of the transmission box 500. A fifth bevel gear 531 is fixed to one end of the third shaft 530. A third bevel gear 522 that mates with the fifth bevel gear 531 is fixed to the other end of the second shaft 520. A sixth bevel gear 532 is fixed to the other end of the third shaft 530. A seventh bevel gear 540 that mates with the sixth bevel gear 532 is fixed to one end of the screw 620.
[0055] Specifically, when the second shaft 520 rotates, it drives the third bevel gear 522 to rotate. The third bevel gear 522 drives the fifth bevel gear 531 to rotate. At this time, the third shaft 530 drives the sixth bevel gear 532 to rotate. The sixth bevel gear 532 drives the seventh bevel gear 540 to rotate, causing the screw 620 to drive the material distribution plate 630 to reciprocate on the discharge port.
[0056] In some embodiments, two plate bodies 320 are respectively connected to both ends of the first shaft 510.
[0057] Specifically, the user can connect the first shaft 510 to a gear set within another plate body 320. Thus, a single driving force can drive another set of transmission components, the scraping component 400, and the material distribution component 600.
