Description

Technical Field

[0001] The invention relates to the technical field of garbage sorting, and in particular to a construction garbage sorting device. Background Art

[0002] With the acceleration of urbanization and the rapid development of the construction industry, the amount of construction waste is increasing. Construction waste mainly includes concrete blocks, bricks, wood, metal, plastic, etc. If these wastes are directly landfilled or piled up without treatment, they will not only occupy a large amount of land resources, but also pollute the environment. Therefore, construction waste can be recycled through sorting. Sorting of construction waste usually requires preliminary screening to achieve preliminary sorting of materials. Traditional construction waste preliminary screening devices usually use simple screens or drum screens to classify the size of the waste through mechanical vibration or rotation. However, wooden boards, plastic parts and aggregates of similar sizes cannot be separated, resulting in the subsequent increase of manual sorting operators or the need to add more screening steps.

[0005] Furthermore, the flow guide mechanism comprises a round rod and a flow guide plate, and the round rod is arranged at the end of the flow guide plate facing the screening channel.

[0006] Furthermore, the material removing and anti-hanging device includes a rotating drive mechanism installed on a frame, the output shaft of the rotating drive mechanism is connected to a material removing shaft, and material removing rods are arranged on the circumferential wall of the material removing shaft. The rotating drive mechanism is used to drive the material removing rod to rotate, thereby removing the material hanging on the round rod.

[0007] Furthermore, it also includes a scraper and anti-winding mechanism, which is installed on the frame and is used to scrape off the material wound around the material-diverting shaft.

[0008] Furthermore, the scraper anti-winding mechanism includes a mounting rod, the mounting rod is mounted on the frame, a plurality of scraper rods are arranged on the mounting rod, and one end of the scraper rod away from the mounting rod is adjacent to the material removing shaft.

[0009] Furthermore, the output shaft of the rotary drive mechanism is connected to the material-moving shaft via a flexible member.

The screening component is arranged in an inclined downward direction, so as to utilize the self-gravity of the waste for separation. Part of the small-particle-size materials fall from the screening dropping port to achieve the first-layer screening. The remaining materials are output from the end of the screening component along the flow direction. Among them, heavy materials (aggregates) with larger size and density, due to the larger inertial speed of forward rolling, will enter the diversion mechanism and be received by the diversion mechanism to achieve the second-layer screening. While larger light materials (such as wood and plastic bags), due to the smaller inertial speed of forward movement, will be blocked by the diversion mechanism, so that the light materials will fall from the gap between the diversion mechanism and the lowermost screening component to achieve the third-layer screening. The material deflecting and anti-hanging device is arranged on the side of the diversion mechanism facing the screening channel, and can timely deflect the materials (mainly large plastic bags) hanging on the diversion mechanism to prevent the materials from accumulating on the diversion mechanism and ensure the continuity and stability of the separation process. The phenomenon of material hanging is reduced, and the accuracy and reliability of separation are also improved.

[0022] Please refer to Figure 1 and Figure 2 , a construction waste sorting device in a preferred embodiment provided by the present invention includes a frame 100, a stepped frame 200, a screening component 300, a diversion mechanism 400, and a material pushing and anti-hanging device 500, and is used for preliminarily coarsely screening construction waste.

[0023] The stepped frame 200 is movably installed on the frame 100. The stepped frame 200 forms a screening channel 210, and a feeding port 211 is provided at the upper end of the screening channel 210; a vibration driving mechanism 220 is installed on the stepped frame 200, and the vibration driving mechanism 220 may specifically be a vibration motor.

[0024] The screening component 300 is arranged in the screening channel 210 and is arranged in an inclined downward direction to guide the material to flow towards the lowermost screening component 300, so as to perform screening by using the self-gravity of the waste. The material output side of the lowermost screening component 300 can be regarded as the material screening outlet 212. The screening component 300 is provided with a screening dropping port 311, so that part of the material drops from the screening dropping port 311 and the remaining material is output from the end of the screening component 300 along the flowing direction; specifically, the screening component 300 includes a plurality of screening rods 310 arranged in the width direction of the screening channel 210. There are gaps between the screening rods 310 to form the screening dropping port 311, so that small materials can drop and be screened out.

[0025] The diversion mechanism 400 is spaced and arranged below the side of the material output side of the lowermost screening component 300. The material output side of the lowermost screening component 300 is the side of the lowermost screening component 300 facing away from other screening components 300. For example, if the screening components 300 are arranged in a direction inclined downward to the left, the lowermost screening component 300 is the screening component 300 at the end of the arrangement direction, that is, the leftmost screening component 300, and the material output side of the leftmost screening component 300 is the left side of the leftmost screening component 300, and the diversion mechanism 400 is spaced and located below the left side of the leftmost screening component 300.

[0026] A blanking gap is formed between the diversion mechanism 400 and the lowermost screening component 300 to allow the light materials to fall. The diversion mechanism 400 is used to receive the heavy materials output from the end of the lowermost screening component 300 and guide this part of the materials in a preset direction. This part of the materials are heavy materials (aggregates) with larger sizes and higher densities, and at the same time block the light materials output from the end of the lowermost screening component 300, so that other materials fall from the gap between the diversion mechanism 400 and the screening component 300. Other materials are light materials with larger sizes and lower densities.

[0027] Specifically, with the vibration of the vibration drive mechanism 220, the materials flow downward along the arrangement direction of the screening component 300, and during the flowing process, the smaller materials in the materials are screened out and fall into the lower first conveying mechanism 130 from the screening dropping opening 311. In order to concentrate the materials and prevent the materials from falling out of the first conveying mechanism 130, the width dimension of the first conveying mechanism 130 can also be reduced. As Figure 3 shown, a collecting funnel 120 can be arranged at the bottom of the step frame 200.

[0028] The larger materials then flow downward and are output from the material output side of the lowermost screening component 300. The larger materials are usually coarse aggregates, larger plastics, wooden boards, etc. Coarse aggregates belong to heavy materials with higher densities, and plastics and wooden boards belong to light materials with lower densities.

[0029] The material deflecting and anti-hanging device 500 is arranged on the side of the diversion mechanism 400 facing the screening channel 210 and is used to deflect the materials hanging on the end of the diversion mechanism 400 close to the screening channel 210. Usually, due to the greater inertia, the materials with higher densities have a certain initial velocity when output from the material screening outlet 212, will be thrown a certain distance and then fall into the diversion mechanism 400 and are guided by the diversion mechanism 400 to the second conveying mechanism 140. Then, the large light materials with lower densities have a lower velocity when output from the material screening outlet 212 due to their lighter weight and smaller inertia, and most of them will fall into the gap between the diversion mechanism 400 and the lowermost screening component 300 and fall into the lower third conveying mechanism 150. Of course, some plastics may also hang on the end of the diversion mechanism 400 close to the screening channel 210, and this part of the materials needs to be processed by the material deflecting and anti-hanging device 500 to make them fall back into the third conveying mechanism 150 again.

[0030] A construction waste sorting device in a preferred embodiment provided by the present invention realizes efficient vibration sorting of construction waste in the screening channel 210 through the combination of the stepped frame 200 and the vibration driving mechanism 220. The vibration driving mechanism 220 can provide stable vibration power to ensure that the waste is fully loosened in the screening channel 210, improving the sorting efficiency. The screening component 300 is arranged in a downward-sloping direction, so as to utilize the self-gravity of the waste for sorting. Part of the small-particle-size materials fall from the screening dropping port 311 to achieve the first-layer screening. The remaining materials are output from the end of the screening component 300 along the flow direction. Among them, heavy materials (aggregates) with larger size and density, due to the greater inertia of forward rolling, will enter the diversion mechanism and be received by the diversion mechanism to achieve the second-layer screening. While larger light materials (such as wood and plastic bags), due to the smaller inertia of forward movement, will be blocked by the diversion mechanism 400, so that the light materials will fall from the gap between the diversion mechanism and the lowermost screening component to achieve the third-layer screening. The material deflecting and anti-hanging device 500 is arranged on the side of the diversion mechanism 400 facing the screening channel, and can timely deflect the materials (mainly large plastic bags) hanging on the diversion mechanism 400, preventing the materials from accumulating on the diversion mechanism 400 and ensuring the continuity and stability of the sorting process. It reduces the phenomenon of material hanging and also improves the accuracy and reliability of sorting. The prior art usually only realizes two-layer screening, and large aggregates and large plastic pieces flow downstream together, requiring more sorting personnel downstream. The idea of the present invention is to further separate a part of the large plastic pieces by using the falling inertia. Of course, there will still be some plastic pieces flowing into the diversion mechanism 400 together with the heavy materials (large aggregates), but the present invention can at least reduce the light materials mixed in the heavy materials, reduce most of the light materials flowing downstream, and reduce the number and workload of downstream sorting personnel.

[0031] Refer to Figure 4 and Figure 5 In some embodiments of the present invention, the diversion mechanism 400 includes a round rod 410 and a diversion plate 420. The round rod 410 is arranged at the end of the diversion plate 420 facing the screening channel 210. The round rod 410 can reduce the impact damage to the materials and also reduce the resistance to the materials, effectively reducing the material hanging. In addition, even the plastic bags hanging on it can be conveniently and smoothly deflected by the material deflecting and anti-hanging device 500 due to the structure of the round rod 410.

[0032] Refer to Figure 4 and Figure 6, in a further embodiment of the present invention, the material feeding anti-hanging device 500 includes a rotary drive mechanism 510 installed on the frame 100. The output shaft of the rotary drive mechanism 510 is connected to a material feeding shaft 520. Material feeding rods 521 are arranged on the peripheral wall of the material feeding shaft 520. The rotary drive mechanism 510 is used to drive the material feeding rods 521 to rotate, so as to dial down the materials hanging on the round rod 410. The rotary drive mechanism 510 drives the material feeding rods 521 to rotate, which can timely dial down the materials hanging on the round rod 410, thereby reducing the materials hanging on the round rod 410. In addition, continuous rotation can timely handle the materials hanging on the round rod 410. In order to limit the dialed-down materials, an arc-shaped baffle 411 is connected to the bottom of the round rod 410 on the side close to the material feeding shaft 520, so that the materials will not be thrown out by the material feeding rods 521 and cannot accurately fall onto the third conveying mechanism 150.

[0033] The directly dropped plastic bags or the parts of the plastic bags dialed down from the round rod by the material feeding rods 521 will be wound around the material feeding shaft 520. After a long time, it is easy for more materials to be wound around the material feeding shaft 520, which will affect the rotation and normal operation of the material feeding shaft 520 and require frequent maintenance and cleaning. For this reason, referring to Figure 2 and Figure 4 , in a further embodiment of the present invention, it further includes a material scraping and anti-winding mechanism 600, which is installed on the frame 100 and is used to scrape off the materials wound around the material feeding shaft 520. The material scraping and anti-winding mechanism 600 can scrape off the materials wound around the material feeding shaft 520, reduce the accumulation of materials on the material feeding shaft 520, further improve the continuity and stability of sorting, and reduce the frequency of maintenance and cleaning.

[0034] Referring to Figure 8In some embodiments of the present invention, the scraper anti-winding mechanism 600 includes a mounting rod 610, which is mounted on the frame 100. A plurality of scraper rods 611 are arranged on the mounting rod 610. One end of the scraper rod 611 away from the mounting rod 610 is adjacent to the material-digging shaft 520, so that when the material-digging shaft 520 rotates, the end of the scraper rod 611 adjacent to the material-digging shaft 520 can scrape off the material wound on the material-digging shaft 520 to prevent the material from accumulating and winding around the material-digging shaft 520. Usually, as soon as a plastic bag is rewound on the material-digging shaft 520, it will be scraped off by the scraper rod 611. The plastic bag has not been wound around the material-digging shaft 520 for many turns, so that the plastic bag has not been tightly wrapped around the material-digging shaft 520 at this time and is easily scraped off by the scraper rod 611. The resistance is not large and the normal rotation of the material-digging shaft 520 is not affected. It can be understood that the connection position between the material removing rod 521 and the material removing shaft 520 is most likely to be entangled with materials such as plastic bags. For this reason, there are usually two scraper rods 611 on both sides of each material removing rod 521, and the material removing rod 521 will pass through the gap between the two scraper rods 611, that is, multiple groups of scraper rods 611 will be provided, and there will be two scraper rods 611 in the same group. The number of groups of scraper rods 611 will be greater than or equal to the number of material removing rods 521, that is, it is ensured that the material removing rod 521 will correspond to a group of scraper rods 611, so that the group of scraper rods 611 will be adjacent to the corresponding material removing rods 521 on both sides, and the root position where the material removing rod 521 is connected to the material removing shaft 520 is scraped and cleaned in a targeted manner.

[0035] Reference Figure 6 and Figure 7 In some embodiments of the present invention, the output shaft of the rotary drive mechanism 510 is connected to the material-discharging shaft 520 via a flexible member 530. The deformation capability of the flexible member 530 not only improves the flexibility of the connection, but also reduces the impact force of the material from the material-discharging shaft 520 to the rotary drive mechanism 510 through the buffering effect of the flexible member 530, thereby reducing the impact and damage to the rotary drive mechanism 510 and improving the stability and reliability of the device. The flexible member 530 is arranged in a surrounding manner to achieve multi-position connection, thereby improving the connection stability and the stability of torque transmission.

[0036] Reference Figure 7, in some embodiments of the present invention, a first connecting plate 511 is provided on the output shaft of the rotary drive mechanism 510. The first connecting plate 511 is connected to a first pressing plate 512. A second connecting plate 522 is provided at the end of the material feeding shaft 520. The second connecting plate 522 is connected to a second pressing plate 523. The flexible member 530 has two clamping portions 531. One of the clamping portions 531 is clamped and fixed by the first connecting plate 511 and the first pressing plate 512, and the other clamping portion 531 is clamped and fixed by the second connecting plate 522 and the second pressing plate 523. By clamping and fixing the two clamping portions 531, the transmission of torque is realized. Specifically, the flexible member 530 is annular, that is, both ends of the two clamping portions 531 are connected and fixed by a connecting portion 532, so that neither end of the two clamping portions 531 is disconnected. After the clamping portion 531 is subjected to rotational force, both ends will be stressed, and there will be no situation where only one end is stressed, resulting in the end being disengaged or damaged due to stress concentration, so that the two ends will not easily disengage from the first connecting plate 511 and the first pressing plate 512, the second connecting plate 522 and the second pressing plate 523. If the flexible member 530 is not annular, the two clamping portions 531 are only connected to one end by a connecting portion 532, so that one end of the two clamping portions 531 is disconnected. When the force is large, only one end of the clamping portion 531 is subjected to tensile force, and it is easily pulled out or broken. If both ends are stressed, first, stress concentration at one end can be avoided, and being pulled out can also be avoided, improving the service life of the flexible member 530. In addition, since the flexible member 530 is annular, even if it moves due to pulling, it moves along its own annular contour, without affecting its operation. The flexible member 530 can be made of elastic metal material, canvas, rubber tape, etc.

[0037] Referring to Figure 8 , in some embodiments of the present invention, a scraping portion 612 that bends downward and inclines toward the material feeding shaft 520 is provided at the end of the scraping rod 611 away from the mounting rod 610. A scraping portion 612 that bends downward and inclines toward the material feeding shaft 520 is provided at the end of the scraping rod 611 away from the mounting rod 610. The scraping portion 612 bends downward and inclines, so that the scraped material will not move along the scraping rod 611 toward the mounting rod 610, but will stay between the scraping portion 612 and the material feeding shaft 520, and the scraped material will be taken away by the subsequent rotating material feeding rod 521, and the scraped material will be brought into the lower third conveying mechanism 150.

[0038] Referring to Figure 1 and Figure 3, in some embodiments of the present invention, the stepped rack 200 includes two spaced side plates 230, a screening channel 210 is formed between the two side plates 230, the screening component 300 is connected to the side plates 230, and the two side plates 230 are fixedly connected by a connecting cylinder 231. Through the fixing effect of the connecting cylinder 231, the stability of the stepped rack 200 is improved. It can be understood that the tops of the two side plates 230 are connected together by a connecting frame, and the connecting frame avoids the feeding port 211.

[0039] Referring to Figure 2 and Figure 9 , in some embodiments of the present invention, the stepped rack 200 is elastically and movably installed on the frame 100; a connecting shaft 240 is provided outside the stepped rack 200, a connecting frame 250 is fixedly installed on the connecting shaft 240, the upper end of the connecting frame 250 is connected to a cover plate 252 to clamp and fix the connecting shaft 240, corresponding holes are provided on the connecting frame 250 and the cover plate 252 for connection and fixation by fasteners, and a mounting seat 110 is provided corresponding to the lower part of the connecting frame 250 on the frame 100. An elastic member 260 is installed between the connecting frame 250 and the mounting seat 110, so as to realize the elastic movement of the stepped rack 200. When vibrating, the stepped rack 200 can vibrate elastically, preferably transmit the vibration to the material, and reduce the vibration transmitted to the frame 100, reducing the influence of the vibration on the components installed on the frame 100 and making the components installed on the frame 100 prone to looseness. The mounting seat 110 is provided with a first positioning protrusion 111 protruding upwards, the bottom of the connecting frame 250 is provided with a second positioning protrusion 251, the lower end of the elastic member 260 is sleeved on the first positioning protrusion 111, and the upper end is sleeved on the second positioning protrusion 251. The two ends of the elastic member 260 are limited by the first positioning protrusion 111 and the second positioning protrusion 251, so that the elastic member 260 is stably installed. The elastic member 260 can be a rubber cylinder, a compression spring or other parts with elastic deformation ability. It can be understood that the connecting shaft 240 can be arranged on the outer side surface of the side plate 230, and multiple connecting shafts 240 can be arranged on each side plate 230 to realize multi-position elastic support and improve the support stability. Multiple elastic members can be arranged between each connecting frame 250 and the mounting seat 110 to realize sufficient elastic support.

[0040] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
