Description

Technical Field

[0001] This utility model relates to the field of construction waste sorting technology, and in particular, to a lightweight material interception device. Background Technology

[0002] In the field of waste resource utilization, especially in the recycling of construction waste and municipal solid waste, meticulous sorting and impurity removal of materials are crucial for ensuring the quality of recycled aggregates. Typically, the initial waste disposal process involves multiple steps, including screening, air separation, and manual sorting, to remove lightweight impurities such as plastic film, foam, and rags. However, because lightweight materials (especially plastics) are irregularly shaped, have small density differences, and easily entangle and adhere to aggregates, some plastic lightweight materials remain after the initial processing and continue to the later stages, mixing into the finished aggregate. These residual plastic lightweight materials severely affect the strength, durability, and other key properties of recycled aggregates, limiting their application value in building materials production and engineering construction.

[0003] Currently, most interception devices for lightweight impurities in downstream aggregates in the industry employ fixed screens, baffles, or simple grid structures. These structures achieve interception by installing blocking components in the aggregate conveying channel or discharge port. However, impurities tend to accumulate on the interception surface, causing blockages and hindering aggregate conveying. Furthermore, cleaning typically requires disassembling the screens, baffles, or grids to remove the accumulated lightweight impurities, making the operation cumbersome and requiring frequent cleaning. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a lightweight material interception device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A lightweight material interception device includes: a frame; side baffles fixedly installed on the frame, two side baffles spaced apart on the left and right to form a material drop channel between them; a baffle plate with a material hanging protrusion on its side, having a blocking state and a clearing state, the baffle plate being movably installed on the frame or the side baffles to switch between the blocking state and the clearing state; in the blocking state, the baffle plate blocks the opening on the front side of the material drop channel, and the material hanging protrusion in the blocking state is located on the side of the baffle plate facing the material drop channel; in the clearing state, the baffle plate opens the opening on the front side of the material drop channel; and a baffle rod installed on the frame, at least partially located in the material drop channel, arranged spaced apart in the left and right direction, extending downwards at an angle towards the baffle plate.

[0007] Furthermore, the side plates are provided with first connecting ear plates on both sides, and the front of each of the two side plates is provided with a second connecting ear plate; the first connecting ear plate is provided with a first connecting hole, and the second connecting ear plate is provided with a second connecting hole; when the plate is in the blocking state, the first connecting ear plate and the second connecting ear plate are fitted together and the first connecting hole and the second connecting hole are aligned and a detachable fastener is installed to achieve the connection and fixation of the first connecting ear plate and the second connecting ear plate.

[0008] Furthermore, the side of the baffle plate facing away from the material-hanging protrusion is provided with a reinforcing rod extending in the left-right direction. The two ends of the reinforcing rod extend to the side of the first connecting ear plate and are provided with a third connecting hole aligned with the first connecting hole.

[0009] Furthermore, the baffle plate is hinged to the side baffle plate.

[0010] Furthermore, a hinge shaft spans across the front of the two side baffles, and a hinge plate is provided on the side of the baffle plate facing away from the material hanging protrusion, and the hinge plate is provided with a hinge hole for the hinge shaft to pass through.

[0011] Furthermore, the material stop bars are provided in multiple sets at intervals along the height direction, and the material stop bars in adjacent sets are staggered in the left and right direction.

[0012] Furthermore, the frame is provided with an insertion part, two insertion parts are spaced apart and arranged at intervals along the inclined direction of the stop bar, and the insertion part is provided with a insertion hole, which is arranged in the left-right direction; the insertion holes on the two insertion parts are aligned one to one, and the stop bar is inserted into the corresponding insertion hole.

[0013] Furthermore, the upper inclined end of the stop bar is provided with a bent head.

[0014] Furthermore, the lower end of the baffle rod extends into an insertion hole.

[0015] Furthermore, the lower ends of the side baffles on both sides are arranged close together.

[0016] This utility model has the following beneficial effects:

[0017] The synergistic effect of the baffle plate and the baffle rod effectively improves the reliability of intercepting lightweight plastic materials. The material-hanging protrusions on the side of the baffle plate, in the baffle state, can hook and intercept plastic films, flakes, and other impurities flowing with the aggregate. Simultaneously, since the baffle plate is located in front of the material discharge channel, material remaining on the material-hanging protrusions does not significantly affect the normal flow of aggregate. The baffle rod extends downwards towards the baffle plate, diverting and guiding the aggregate, forcing lightweight impurities to gather towards the baffle plate. Lightweight materials hanging on the baffle rod will also gradually gather towards the baffle plate, preventing them from accumulating on the entire baffle rod and obstructing aggregate flow. Furthermore, opening the baffle plate later facilitates the cleaning of material gathered at the lower inclined end of the baffle rod. Additionally, some lightweight materials will fall from the lower inclined end of the baffle rod onto the baffle plate and be intercepted by the material-hanging protrusions. The baffle plate is movable and has a switching function between baffle and cleaning states, completely eliminating the drawback of traditional devices that require complete disassembly for cleaning. When the baffle plate is switched to the cleaning state, it opens the opening on the front side of the material discharge channel, allowing the intercepted and accumulated lightweight plastic materials to be discharged directly from the opening or quickly cleaned up without having to go deep into the equipment or disassemble parts, which significantly reduces the difficulty and frequency of cleaning operations.

[0038] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a lightweight material interception device, comprising a frame 100, a side baffle 200, a baffle plate 300, and a baffle rod 400.

[0039] Side baffles 200 are fixedly installed on the frame 100. Two side baffles 200 are arranged at intervals on the left and right sides to form a material drop channel 210 between them. The material drop channel 210 has openings on the front, rear and bottom sides.

[0040] The baffle plate 300 has a material-hanging protrusion 310 on its side. The baffle plate 300 has a blocking state and a cleaning state. The baffle plate 300 is movably installed on the frame 100 or the side baffle 200 to switch between the blocking state and the cleaning state. In the blocking state, the baffle plate 300 blocks the opening on the front side of the material discharge channel 210. The material-hanging protrusion 310 in the blocking state is located on the side of the baffle plate 300 facing the material discharge channel 210, and the material-hanging protrusion 310 in the blocking state is located on the rear side of the baffle plate 300. (Refer to...) Figure 3 and Figure 6 When the baffle plate 300 is in the cleaning state, it opens the opening on the front side of the material drop channel 210, thereby facilitating the cleaning of the material stuck on the material hanging protrusion 310.

[0041] The baffle rod 400 is installed on the frame 100. The baffle rod 400 is at least partially located in the material discharge channel 210. The baffle rods 400 are arranged at intervals in the left and right direction. The baffle rods 400 extend downwards towards the baffle plate 300, that is, the front end of the baffle rod 400 is inclined downwards, thereby guiding the lightweight material to move along the baffle rod 400 towards the baffle plate 300.

[0042] The present invention provides a lightweight material interception device, which effectively improves the reliability of intercepting lightweight plastic materials through the synergistic effect of the baffle plate 300 and the baffle rod 400. When the baffle plate 300 is in the baffle state, the hanging protrusion 310 on its side can hook and intercept plastic film, sheet-like impurities, etc. that flow with the aggregate. At the same time, since the baffle plate 300 is located in front of the material drop channel 210, the material remaining on the hanging protrusion 310 does not affect the normal flow of aggregate. The baffle rod 400 extends downward towards the baffle plate 300, which can divert and guide the aggregate, forcing light impurities to gather in the direction of the baffle plate 300. The light material hanging on the baffle rod 400 will also slowly gather in this direction, preventing light material from accumulating on the entire baffle rod 400 and causing the aggregate to flow poorly. After the baffle plate 300 is opened, it is also convenient to clean the material gathered at the lower end of the inclined baffle rod 400. In addition, some light material will fall from the lower end of the inclined baffle rod 400 onto the baffle plate 300 and be intercepted by the hanging protrusion 310. The baffle plate 300 adopts a movable installation method and has the function of switching between baffle and cleaning states, completely changing the drawbacks of traditional devices that require complete disassembly of the interception device for cleaning or personnel to enter the equipment for cleaning. When the baffle plate 300 is switched to the cleaning state, it opens the opening on the front side of the material discharge channel 210, allowing the intercepted and accumulated lightweight plastic materials to be discharged directly from the opening or quickly swept away, without having to enter the equipment or disassemble parts, significantly reducing the difficulty and frequency of cleaning operations.

[0043] Reference Figure 2 and Figure 7 In some embodiments of this utility model, the baffle plate 300 is provided with first connecting ear plates 320 on both sides, and the front side of each of the two side baffle plates 200 is provided with a second connecting ear plate 220. The first connecting ear plate 320 is provided with a first connecting hole 321, and the second connecting ear plate 220 is provided with a second connecting hole 221. In the baffle state, the first connecting ear plate 320 and the second connecting ear plate 220 are fitted together, and the first connecting hole 321 and the second connecting hole 221 are aligned and installed with detachable fasteners to achieve the connection and fixation of the first connecting ear plate 320 and the second connecting ear plate 220. The detachable fasteners include bolts and nuts. The bolts pass through the first connecting hole 321 and the second connecting hole 221 and are connected to the nuts, thereby clamping and fixing the first connecting ear plate 320 and the second connecting ear plate 220. Through the holes of the first connecting ear plate 320 and the second connecting ear plate 220 and the fasteners, the baffle plate 300 is reliably fixed in the baffle state, making the working position firm and stable.

[0044] Reference Figure 5 and Figure 7In a further embodiment of this utility model, a reinforcing rod 330 extending in the left-right direction is provided on the side of the baffle plate 300 facing away from the material-hanging protrusion 310. The two ends of the reinforcing rod 330 extend to the side of the first connecting ear plate 320 and are provided with a third connecting hole aligned with the first connecting hole 321 for fasteners to pass through and be installed. The reinforcing rod 330 is specifically a channel steel strip, which is fixed to the side of the baffle plate 300 by welding. The reinforcing rod 330 significantly enhances the overall structural strength of the baffle plate 300, especially when intercepting a large amount of lightweight impurities or being impacted by aggregates. The extension of the two ends of the reinforcing rod 330 to the first connecting ear plate 320 effectively strengthens the structural strength of the first connecting ear plate 320, preventing the first connecting ear plate 320 from deforming and being damaged due to stress concentration.

[0045] Reference Figure 5 In a further embodiment of this utility model, the baffle plate 300 is hinged to the side baffle plate 200. The hinge allows the baffle plate 300 to rotate and open, which has the advantages of easier operation and more stable switching compared to other movable connection methods.

[0046] Reference Figure 5 In a further embodiment of this utility model, a hinge shaft 230 spans the front of the two side baffles 200, with both ends of the hinge shaft 230 fixed to the front of the two side baffles 200 respectively. A hinge plate 340 is provided on the side of the baffle plate 300 facing away from the material hanging protrusion 310, and the hinge plate 340 has a hinge hole for the hinge shaft 230 to pass through. The hinge shaft 230 spans the two side baffles 200, providing a symmetrical and stable rotation fulcrum for the baffle plate 300.

[0047] Reference Figure 2 , Figure 4 and Figure 8 In a further embodiment of this utility model, multiple sets of baffle rods 400 are spaced apart along the height direction, and adjacent sets of baffle rods 400 are staggered in the left-right direction. The multiple sets of baffle rods 400 spaced apart along the height direction and staggered left-right arrangement form a three-dimensional interception barrier, improving the interception effect. The staggered arrangement structure avoids straight gaps, preventing lightweight impurities from leaking through gaps in the same vertical direction, further reducing the leakage rate.

[0048] Reference Figure 2 , Figure 4 and Figure 8In a further embodiment of this utility model, the frame 100 is provided with insertion parts 110. Two insertion parts 110 are spaced apart and arranged at intervals along the inclined direction of the baffle rods 400. That is, two insertion parts 110 are provided for a group of baffle rods 400 at the same height. The heights of the two insertion parts 110 are different to accommodate the inclination of the baffle rods 400. Insertion parts 110 are provided with insertion holes 111, which are arranged in the left-right direction. The insertion holes 111 on the two insertion parts 110 are aligned one-to-one, and the baffle rods 400 are inserted into the corresponding insertion holes 111. The insertion holes 111 enable quick positioning and installation of the baffle rods 400. By selecting different positions of the insertion holes 111, the spacing distance of the baffle rods 400 can be flexibly adjusted to adapt to the interception requirements of aggregates and impurities of different particle sizes, thereby improving the versatility of the device.

[0049] Reference Figure 4 and Figure 8 In a further embodiment of this utility model, the upper inclined end of the stop rod 400 is provided with a bending head 410. The bending head 410 at the upper inclined end of the stop rod 400 prevents the stop rod 400 from sliding down along the insertion hole 111 and falling off under the impact of aggregate. The bending head 410 cannot pass through the insertion hole 111, thereby limiting the stop rod 400.

[0050] Reference Figure 4 and Figure 8 In a further embodiment of this utility model, the lower end of the baffle rod 400 extends into the insertion hole 111. This provides the lower end of the baffle rod 400 with redundant length passing through the insertion hole 111, preventing the baffle rod 400 from dislodging from the corresponding insertion hole 111 due to slight shaking and improving the installation stability of the baffle rod 400.

[0051] Reference Figure 4 and Figure 8 In a further embodiment of this utility model, the lower ends of the side baffles 200 on both sides are arranged close together. The close arrangement of the lower ends of the side baffles 200 on both sides creates a gradual structure in the material drop channel 210 that is wider at the top and narrower at the bottom. This structure can collect the falling aggregate. The wide opening at the top of the material drop channel 210 facilitates accurate reception of materials conveyed by the first conveyor belt 101 above, preventing materials from falling off the outside of the material drop channel 210. The narrow bottom of the material drop channel 210 ensures that the materials fall precisely onto the second conveyor belt 102 below.

[0052] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
