Description

Technical Field

[0001] The invention relates to the technical field of waste treatment, and in particular to a waste collection device for manufacturing building materials. Background Art

[0002] Building materials are a general term for materials used in civil engineering and construction projects, including ceramics, glass, engineering plastics, composite materials, coatings, veneers and various tiles. With the development of the times, more and more composite materials are widely used in the field of building materials manufacturing. In order to respond to the call for energy conservation and environmental protection, waste materials used in building materials manufacturing have begun to be recycled.

[0003] Existing collection equipment, such as a waste collection device for building material manufacturing disclosed in announcement number CN218573782U, wherein the driving gear and the driven gear rotate simultaneously to drive the crushing roller connected to the rotating rod to rotate relatively, thereby achieving the crushing of building materials, and at the same time, humidification is performed through the atomizing nozzle to reduce dust from the waste. However, the use of a single form of rolling crushing method is not only inefficient, but also cannot guarantee the crushing effect of the building material waste. Although the humidification method can reduce the diffusion of dust, it fails to remove impurities with no recycling value from the building material waste, and also cannot guarantee the cleanliness of the recycled building material waste. Similarly, a new type of waste recovery device for building material manufacturing disclosed in announcement number CN219807467U also starts the first motor to drive the two crushing disks to rotate and crush the waste inside. The second motor and the conveyor belt cooperate with each other to facilitate the transmission of the crushed waste. The use of the feed shaft allows the device to rotate a certain angle, but it is difficult to finely crush the building material waste, so it is very easy to cause blockage in the tortuous equipment passage. It can only be blocked by setting a large number of feeding measures, which in turn increases the difficulty of waste collection and treatment and the equipment manufacturing cost.

It is worth noting that when the wedge drive rod 21 moves upward, under the action of the tension of the return spring 24, the telescopic slide rod 22 has a tendency to move out of the middle cavity 102.

[0055] The upper grinding block 25 and the lower grinding block 26 are respectively fixedly mounted on the inner ends of the two telescopic slide rods 22 located in the middle cavity 102.

[0057] The crushing mechanism is driven by the second motor 3, and the crushing mechanism is arranged in the noise reduction chassis 1 through the lower chamber 103. Figure 1 , Attachment Figure 2 , Attachment Figure 4 With attached Figure 5 The crushing mechanism includes a driving crushing roller 27 and a driven crushing roller 28, and a driving gear 29 and a driven gear 30 that are meshed and connected: The driving roller 27 and the driven roller 28 are both rotatably mounted in the lower cavity 103, and the driving roller 27 is fixedly connected to the output end of the second motor 3; The driving gear 29 and the driven gear 30 are key-connected to the driving rolling roller 27 and the driven rolling roller 28 respectively. Under the transmission action of the driving gear 29 and the driven gear 30, the driving rolling roller 27 and the driven rolling roller 28 rotate in opposite directions to roll the construction waste.

[0058] The funnel opening is located between the air inlet 105 and the dust outlet 106, so that the airflow can drive the falling building material fragments containing impurities during the horizontal movement.

[0059] The air inlet 105 corresponds horizontally to the dust outlet 106, and the cross section of the dust outlet 106 is an inverted V-shaped structure. Figure 3 The dust discharge port 106 is composed of an upslope surface and a downslope surface, ensuring that only lightweight impurities that are easily affected by wind can cross the upslope surface and then be discharged out of the noise reduction chassis 1 through the downslope surface. Even if heavy building material waste is driven to the dust discharge port 106 by wind, it is difficult to cross the upslope surface to reach the downslope surface, and will eventually fall back into the middle cavity 102.

[0060] A synchronous pulley 6 is connected between the lower rotating shaft 4 and the upper rotating shaft 5 via a coupling.

[0061] The driving laminating roller 27 and the driven laminating roller 28 correspond horizontally.

[0062] It should be noted that the specific models and specifications of the first motor 2 and the second motor 3 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0063] The present invention can be explained by the following operation mode: The building material waste mixed with impurities is introduced into the upper chamber 101 through the feed port 104, and the first motor 2 and the second motor 3 are controlled to start; The first motor 2 drives the lower rotating shaft 4 to rotate, and the lower rotating shaft 4 drives the upper rotating shaft 5 to rotate synchronously through the synchronous belt pulley 6; The upper rotating shaft 5 drives the first push rod 9 and the second push rod 10 to rotate synchronously through the outer flange 7 and the inner flange 8; When the first push rod 9 contacts the lifting extension block 1202, the lifting plate 12 moves vertically upward along the guide block 11, so that the lifting plate 12 drives the boosting protrusion 15 to be lifted to a high position in the upper chamber 101 through the synchronous bracket 14; When the second push rod 10 contacts the driven swing rod 1303, the driven swing rod 1303 drives the driven baffle 1304 to deflect through the deflection shaft 1301, and the driven baffle 1304 is separated from the positioning extension block 1203. The lifting plate 12, which loses the limiting support function, drives the boosting protrusion 15 to descend to the low position in the upper chamber 101 through the synchronous bracket 14; When the lifting plate 12 drives the limit extension block 1204 to move down to the low position, the limit extension block 1204 is clamped on the stop rod 130903 through the column groove, so that the lifting slider 130901 and the profile frame 130902 move down synchronously, and the profile frame 130902 drives the driving piston 1306 to shrink into the middle tube 130503 to squeeze the two driven pistons 1310, so that the driven piston 1310 stretches the strong spring 1311 during the extension process of the side tube 130502. Because of the buffer support effect, the lifting plate 12 drives the boosting protrusion 15 to rise and fall repeatedly in the upper chamber 101 to repeatedly pressurize the building material waste; The lifting plate 12 eventually becomes stable, because the elastic force of the strong torsion spring 1302 causes the deflection shaft 1301 to drive the driven baffle 1304 to contact the positioning extension block 1203, so as to limit and fix the lifting plate 12; The block-shaped building material waste obtained after the initial crushing enters the middle cavity 102 and falls on the upper grinding block 25. The lower rotating shaft 4 drives the traction turntable 16 to rotate. The traction turntable 16 drives the reciprocating swing rod 18 to swing up and down and horizontally along the guide frame 17 through the movably connected driven long hole 1801 and the traction yoke 1601. The reciprocating swing rod 18 drives the lifting frame 19 to lift vertically through the traction connecting rod 20. When the lifting frame 19 drives the two wedge head driving rods 21 to move vertically downward, it applies pressure to the wedge head driven block 23, so that the reset spring 24 is compressed and contracted. Under the tension of the reset spring 24, the telescopic slide rod 22 drives the upper grinding block 25 and the lower grinding block 26 to move toward or in the opposite direction. The lower grinding block 26 drives the grinding plate 2602 to slide in the upper unloading long hole 2501 to grind and crush the building material waste passing through the upper unloading long hole 2501, and then falls through the lower unloading long hole 2601. When the waste building materials containing light impurities are in free fall, the air inlet 105 inputs airflow into the middle cavity 102 to form a wind force that drives the light impurities to drift horizontally, so that the light impurities are discharged from the noise reduction chassis 1 through the dust outlet 106, and the waste building materials fall vertically into the lower cavity 103; The falling construction waste falls between the driving roller 27 and the driven roller 28, and the second motor 3 drives the driving roller 27 to rotate. The driving roller 27 drives the driven roller 28 to rotate synchronously through the driving gear 29 and the driven gear 30. The driving roller 27 and the driven roller 28 rotating in opposite directions further crush the construction waste, and the crushed powdered construction material fragments are discharged from the noise reduction chassis 1 through the discharge port 107.
