Description
Technical Field
[0001] This utility model relates to the field of drum screen technology for ecological recycling and sorting of construction waste, and more particularly to drum screen for ecological recycling and sorting of construction waste. Background Technology
[0002] The construction waste ecological recycling and sorting drum screen is a specialized piece of equipment for the automated screening and grading of construction waste (such as concrete blocks, bricks, metal fragments, wood chips, etc.). Through the rotation of the drum and the screen structure, mixed waste is separated according to particle size, achieving efficient classification of recyclable aggregates (such as fine sand and gravel) and other materials, thus contributing to the resource utilization and ecological environmental protection goals of construction waste.
[0003] In the field of ecological recycling of construction waste, traditional drum screens usually adopt a drum structure with fixed screen holes, which has a fixed range of screening particle sizes. This makes it difficult to adapt to the characteristics of large particle size differences and complex composition of materials in construction waste. When different particle sizes need to be screened, traditional equipment needs to be stopped to replace the screen, which cannot achieve dynamic adjustment, resulting in operation interruption and reduced ease of operation. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drum screen for the ecological recycling and sorting of construction waste.

[0006] The aforementioned components achieve the following effects: waste is fed into the inner cylinder via the hopper; the outer cylinder rotates to separate the waste within the inner cylinder; a collection basket is placed on the bottom plate to collect waste passing through the filter holes; the filter holes on the two outer cylinders completely overlap to maximize the aperture; a sliding adjustment plate drives the inner cylinder to slide on the outer cylinder to adjust the aperture size, which can be adjusted from small to large; smaller waste is screened first, and then progressively screened to larger diameters; the aperture size can be flexibly adjusted according to actual conditions; and finally, very large waste cannot pass through the filter holes. The cylinder model is CDQ2G40-40DMZ; starting the cylinder causes one end of the bottom plate to rise at a certain angle, making the outer and inner cylinders tilted, allowing large waste to be discharged from the outlet. This avoids the situation where traditional equipment requires stopping to replace the screen when screening materials of different particle sizes, which cannot achieve dynamic adjustment and leads to operation interruption and reduced operational convenience.
[0007] Preferably, two sliders are fixedly connected to the inner cylinder, and the sliders are slidably connected to the outer cylinder.
[0008] The effect achieved by the above components is that the slider slides at the upper limit of the outer cylinder, which allows the outer cylinder and the inner cylinder to rotate synchronously.
[0009] Preferably, a screw is rotatably connected to the slide groove via a bearing, the screw is threadedly connected to an adjusting plate, and a first motor is fixedly connected to the base plate, the screw being driven to rotate by the first motor.
[0010] The effect achieved by the above components is as follows: the output end of the first motor is connected to the screw through a reducer and a coupling. The model of the first motor is 17HS4401. First, the power is turned on to power the control system of the first motor. Then, the first motor is started to drive the screw to rotate, which in turn drives the adjusting plate to slide.
[0011] Preferably, a disc gear is fixedly connected to the outer cylinder, a spur gear is meshed with the disc gear, the spur gear is rotatably connected to the fixed plate through a bearing, a second motor is fixedly connected to the fixed plate, and the spur gear is driven to rotate by the second motor.
[0012] The effect achieved by the above components is as follows: the output end of the second motor is connected to the spur gear through the reducer and coupling. The model of the second motor is Y2-160m1-8. First, the power is turned on to power the control system of the second motor. Then, the second motor is started to drive the spur gear to rotate, which in turn drives the outer cylinder to rotate through the disc gear.
[0013] Preferably, the fixed plate is provided with a cleaning structure, which is mainly composed of a fixed block. The fixed block is fixedly connected to the fixed plate. Both the adjusting plate and the fixed block are provided with sliding grooves. Sliding blocks are slidably connected in the sliding grooves. A cleaning brush is provided on both sliding blocks.
[0014] The effect achieved by the above components is that during the rotation of the outer cylinder, the sliding block causes the cleaning brush to approach the outer cylinder for cleaning, and conversely, the outer cylinder and inner cylinder become clogged, affecting the screening effect.
[0015] Preferably, an adjusting block is slidably inserted on one of the sliding blocks, and the adjusting block is rotatably connected to one end of the cleaning brush via a bearing, and the other end of the cleaning brush is rotatably connected to the sliding block via a bearing.
[0016] The effect achieved by the above components is that when the outer cylinder and the inner cylinder are adjusted by sliding, the adjusting block will slide on the sliding block to adapt to the change in distance between the fixed plate and the adjusting plate.
[0017] Preferably, a sliding rod is fixedly connected to the sliding block, the sliding rod is slidably inserted into the sliding groove, and a friction wheel is fixedly connected to the cleaning brush.
[0018] The above components achieve the following effects: the sliding rod can be slidable to adjust the position of the sliding block, and the friction wheel is made of rubber and is in close contact with the outer side of the outer cylinder. Under the action of friction, the friction wheel drives the cleaning brush to rotate, thereby improving the cleaning effect.
[0019] Preferably, a spring is sleeved on the sliding rod, one end of the spring is fixedly connected to the sliding rod, the other end of the spring is fixedly connected to the fixing block, and the other end of the spring is fixedly connected to the fixing plate.
[0020] The effect achieved by the above components is that when the friction wheel contacts the outer cylinder, the spring is in a stretched state, so the spring's rebound force acts on the sliding rod, making the friction wheel always close to the outside of the outer cylinder.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting an adjustment structure, waste is fed into the inner cylinder through the feeding hopper, and the outer cylinder is rotated to separate the waste in the inner cylinder. A collection basket is placed on the bottom plate to collect the waste that passes through the filter holes. The filter holes on the two outer cylinders are completely overlapped to maximize the aperture. A sliding adjustment plate drives the inner cylinder to slide on the outer cylinder to adjust the aperture size. The adjustment can be made from small to large. Smaller waste materials are screened first, and then screened to larger diameters. The aperture can be flexibly adjusted according to the actual situation. Finally, very large waste materials cannot pass through the filter holes. The cylinder model is CDQ2G40-40DMZ. The cylinder can be started, and the cylinder drives one end of the bottom plate to lift a certain angle, so that the outer cylinder and the inner cylinder are tilted, allowing large waste materials to be discharged from the outlet. This avoids the situation where traditional equipment needs to stop to replace the screen when screening materials of different particle sizes, which cannot achieve dynamic adjustment and leads to operation interruption and reduced operation convenience.

[0024] Example 1, such as Figure 1 As shown, a drum screen for the ecological recycling and sorting of construction waste includes a base 1, a base plate 2 rotatably connected to the base 1 via a hinge, a fixing plate 3 fixedly connected to the base plate 2, and a feeding hopper 4 fixedly connected to the base plate 2.
[0025] Reference Figures 1 to 3An adjustment structure 5 is provided on the fixed plate 3. The adjustment structure 5 mainly consists of an outer cylinder 51, which is fixedly connected to the fixed plate 3. An inner cylinder 52 is slidably inserted into the outer cylinder 51, and an adjustment plate 54 is fixedly connected to the inner cylinder 52. A sliding groove 55 is provided on the bottom plate 2, and the sliding groove 55 is slidably connected to the adjustment plate 54. A cylinder 58 is rotatably connected to the base 1, and one end of the cylinder 58 is rotatably connected to the bottom plate 2. Waste is fed into the inner cylinder 52 through the feeding hopper 4. Rotating the outer cylinder 51 causes the waste to be separated in the inner cylinder 52. A collection basket is provided on the bottom plate 2 to collect the waste that passes through the filter holes. The filter holes on the two outer cylinders 51 are completely overlapped to maximize the pore size. The adjustable cylinder 51 can slide. The section plate 54 drives the inner cylinder 52 to slide on the outer cylinder 51 to adjust the aperture size. The adjustment can be made from small to large, first screening smaller waste materials and then progressively screening larger diameter materials. The aperture size can be flexibly adjusted according to actual conditions. Finally, very large waste materials cannot pass through the filter holes. The cylinder 58 (model CDQ2G40-40DMZ) can be activated, causing one end of the base plate 2 to rise at a certain angle, tilting the outer cylinder 51 and inner cylinder 52. This allows large waste materials to be discharged from the outlet, thus avoiding the need to stop and replace screens in traditional equipment when screening materials of different sizes, preventing dynamic adjustment and operation interruptions, and reducing operational convenience. In this configuration, two sliders 53 are fixedly connected to the inner cylinder 52. The sliders 53 are slidably connected to the outer cylinder 51, and the sliders 53 slide at the upper limit of the outer cylinder 51, allowing the outer cylinder 51 and the inner cylinder 52 to rotate synchronously. A screw 56 is rotatably connected to the slide groove 55 via a bearing. The screw 56 is threadedly connected to the adjusting plate 54. A first motor 57 is fixedly connected to the base plate 2. The screw 56 is driven to rotate by the first motor 57. The output end of the first motor 57 is connected to the screw 56 via a reducer and a coupling. The model of the first motor 57 is 17HS4401. First, the power is turned on to power the control system of the first motor 57. Then, starting the first motor 57 can drive the screw 56 to rotate. The movement causes the adjusting plate 54 to slide. A disc gear 59 is fixedly connected to the outer cylinder 51, and a spur gear 510 is meshed with the disc gear 59. The spur gear 510 is rotatably connected to the fixed plate 3 through a bearing. A second motor 511 is fixedly connected to the fixed plate 3. The spur gear 510 is driven to rotate by the second motor 511. The output end of the second motor 511 is connected to the spur gear 510 through a reducer and a coupling. The model of the second motor 511 is Y2-160m1-8. First, the power is turned on to power the control system of the second motor 511. Then, the second motor 511 is started, which can drive the spur gear 510 to rotate, and then drive the outer cylinder 51 to rotate through the disc gear 59.
[0026] Reference Figure 4 and Figure 5A cleaning structure 6 is provided on the fixed plate 3. The cleaning structure 6 is mainly composed of a fixed block 61, which is fixedly connected to the fixed plate 3. Both the adjusting plate 54 and the fixed block 61 are provided with sliding grooves 62. Sliding blocks 63 are slidably connected in the sliding grooves 62. A cleaning brush 64 is provided on both sliding blocks 63. During the rotation of the outer cylinder 51, the sliding blocks 63 move the cleaning brush 64 close to the outer cylinder 51 to clean it. Otherwise, the outer cylinder 51 and the inner cylinder 52 will be blocked, affecting the screening effect. An adjusting block 67 is slidably inserted on one of the sliding blocks 63. One end of the adjusting block 67 is rotatably connected to one end of the cleaning brush 64 through a bearing, and the other end of the cleaning brush 64 is rotatably connected to the sliding block 63 through a bearing. When the outer cylinder 51 and the inner cylinder 52 are slidably adjusted, the adjusting block 67 will slide on the sliding block 63 to adapt to the movement of the fixed plate 3 and the adjusting plate 54. The distance between 4 changes, a sliding rod 65 is fixedly connected to the sliding block 63, the sliding rod 65 is slidably inserted into the sliding groove 62, a friction wheel 68 is fixedly connected to the cleaning brush 64, the position of the sliding block 63 can be adjusted by sliding the sliding rod 65, and the friction wheel 68 is made of rubber and is in close contact with the outer side of the outer cylinder 51. Under the action of friction, the friction wheel 68 drives the cleaning brush 64 to rotate, improving the cleaning effect. A spring 66 is sleeved on the sliding rod 65, one end of the spring 66 is fixedly connected to the sliding rod 65, the other end of the spring 66 is fixedly connected to the fixed block 61, and the other end of the spring 66 is fixedly connected to the fixed plate 3. When the friction wheel 68 contacts the outer cylinder 51, the spring 66 is in a stretched state, so the rebound force of the spring 66 acts on the sliding rod 65, so that the friction wheel 68 is always in close contact with the outer side of the outer cylinder 51.
[0027] Working principle: Waste is fed into the inner cylinder 52 via the feeding hopper 4. The outer cylinder 51 rotates, causing the waste to separate within the inner cylinder 52. A collection basket is placed on the bottom plate 2 to collect waste that passes through the filter holes. The filter holes on the two outer cylinders 51 completely overlap to maximize the aperture. A sliding adjustment plate 54 drives the inner cylinder 52 to slide on the outer cylinder 51 to adjust the aperture size. Adjustment can be made from small to large, first screening smaller waste materials and then progressively screening larger diameter materials. The aperture size can be flexibly adjusted according to actual conditions. Finally, very large waste materials cannot pass through the filter holes. The cylinder 58 is model CDQ2G40-40. The DMZ can start the cylinder 58. The cylinder 58 drives one end of the base plate 2 to rise at a certain angle, so that the outer cylinder 51 and the inner cylinder 52 are tilted, allowing large waste materials to be discharged from the outlet. This avoids the situation where traditional equipment needs to stop to replace the screen when screening materials of different particle sizes, which cannot achieve dynamic adjustment and causes operation interruption, reducing the convenience of operation. The slider 53 slides at the upper limit of the outer cylinder 51, which can make the outer cylinder 51 and the inner cylinder 52 rotate synchronously. The output end of the first motor 57 is connected to the screw 56 through a reducer and a coupling. The model of the first motor 57 is 17HS4401. First, the power is connected to the first motor. The control system of motor 57 is powered on, and then the first motor 57 is started, which drives the screw 56 to rotate, thereby causing the adjusting plate 54 to slide. The output end of the second motor 511 is connected to the spur gear 510 through a reducer and a coupling. The model of the second motor 511 is Y2-160m1-8. First, the power is turned on to power the control system of the second motor 511, and then the second motor 511 is started, which drives the spur gear 510 to rotate, and then drives the outer cylinder 51 to rotate through the disc gear 59. During the rotation of the outer cylinder 51, the sliding block 63 makes the cleaning brush 64 approach the outer cylinder 51 to clean it. Conversely, the outer cylinder 51 and the inner cylinder... 52. Blockage affects the screening effect. When the outer cylinder 51 and inner cylinder 52 are slidably adjusted, the adjusting block 67 will slide on the sliding block 63 to adapt to the change in distance between the fixed plate 3 and the adjusting plate 54. The position of the sliding block 63 can be adjusted by sliding the sliding rod 65. The friction wheel 68 is made of rubber and is in close contact with the outer side of the outer cylinder 51. Under the action of friction, the friction wheel 68 drives the cleaning brush 64 to rotate, improving the cleaning effect. When the friction wheel 68 contacts the outer cylinder 51, the spring 66 is in a stretched state. Therefore, the rebound force of the spring 66 acts on the sliding rod 65, so that the friction wheel 68 is always in close contact with the outer side of the outer cylinder 51.
