Description

Technical Field

[0001] This utility model relates to a processing device, specifically an environmentally friendly construction waste resource recovery processing device, belonging to the field of construction waste treatment technology. Background Technology

[0002] Construction waste includes slag, waste concrete, and waste bricks and stones generated during construction production activities such as demolition, construction, decoration, and repair. The treatment of construction waste is often limited to crude crushing and simple screening, which cannot classify and collect small and large particles, such as concrete. After being recycled, it can be made into recycled coarse and fine aggregates, which can partially or completely replace natural coarse and fine aggregates, thus reducing the waste of resources. The recycling of waste requires processing equipment.

[0003] A construction waste treatment device disclosed in Chinese Patent Application Publication CN221046166U uses a crushing component to crush materials and transfer them to a screen plate. A vibration component drives the screen plate to screen the materials. By using a vibration component that is directly or indirectly connected to the screen plate and the support plate through a transmission rod, the support plate or screen plate can be vibrated directly or indirectly, thereby preventing long-term dust adhesion or preventing some solids from getting stuck in a certain part and interfering with the smooth operation of the device.

[0004] The aforementioned patent has certain drawbacks in its use. Firstly, it only uses a single screen plate for screening. The material particles after being crushed by the crushing component are of different sizes, which may clog the screen plate during screening, affecting subsequent screening operations. Secondly, a single screen plate cannot separate coarse and fine aggregates, requiring additional screening devices to separate the coarse and fine aggregates in subsequent operations, resulting in low efficiency of the entire process.

[0005] Therefore, an environmentally friendly construction waste resource recovery device is proposed here. Utility Model Content

[0006] This utility model proposes an environmentally friendly construction waste resource utilization device to solve the problem of screen plate clogging during screening operations in common waste treatment devices in the prior art. At the same time, it can separate coarse aggregate and fine aggregate during the screening process, thereby improving the efficiency of the entire process.

[0007] This utility model is achieved through the following technical solution: an environmentally friendly construction waste resource utilization device, including a box, an outer cylinder fixed to the inner wall of the box, a screening device inside the outer cylinder, the screening device including a screen cylinder, the screen cylinder being rotatably connected to the outer cylinder, two fixing plates fixed to the inner wall of the box, a sweeping rod rotatably connected between the two fixing plates, a brush installed on the outer surface of the sweeping rod, the brush contacting the screen cylinder, a sweeping sprocket fixed on the outer surface of the sweeping rod, a drive motor installed on the side of the outer cylinder, a drive sprocket installed at the output end of the drive motor, and the drive sprocket and the sweeping sprocket being connected by chain drive.

[0008] A connecting rod is installed at the output end of the drive motor. A fixing rod is fixed to the outer surface of the connecting rod. The fixing rod is fixed to the screen cylinder. The drive motor can drive the connecting rod to rotate, which in turn drives the fixing rod to rotate, thereby driving the screen cylinder to rotate.

[0009] A feed pipe is installed on the side of the outer cylinder, and multiple baffles are fixed on the inner wall of the screen cylinder. The crushed concrete material can enter the screen cylinder through the feed pipe, and the baffles can block the material to prevent it from leaving the screen cylinder before it is fully screened.

[0010] The screening device also includes two support plates fixed to the inner wall of the box. A filter plate is slidably connected to the upper surface of the two support plates. The filter plate has a smaller filter opening size than the screen cylinder, and the material can be screened a second time through the filter plate.

[0011] The inner wall of the box is equipped with a conveyor belt, and the outer side of the box is provided with an auxiliary device. The auxiliary device includes a track plate fixed to the side of the box, a movable plate slidably connected to the inner wall of the track plate, and two toothed plates fixed to the inner side wall of the movable plate. The movable plate and the filter plate are fixed together by a connecting block.

[0012] Furthermore, an outer shell is fixed to the outer side of the housing, and an auxiliary motor is installed on the inner wall of the outer shell. A half gear is fixed to the output end of the auxiliary motor. The half gear meshes with two toothed plates, and the rotation of the half gear can drive the moving plate to reciprocate.

[0013] An auxiliary sprocket is installed at the output end of the auxiliary motor, and a driven sprocket is installed on the side of the housing. The driven sprocket is connected to the conveyor belt, and the auxiliary sprocket and the driven sprocket are connected by chain drive.

[0014] This utility model provides an environmentally friendly construction waste resource recovery device, which has the following beneficial effects:

[0015] 1. This environmentally friendly construction waste resource recovery device uses a screen cylinder to perform preliminary screening of materials crushed by the crushing device. During the screening process, the rotation of the screen cylinder prevents materials from clogging the screen holes. At the same time, the rotation of the cleaning rod can drive the brush to further clean the outer surface of the screen cylinder, thus solving the problem of clogging that often occurs in existing waste treatment devices during screening operations.

[0016] 2. This environmentally friendly construction waste resource recovery device uses a screen cylinder for initial screening of materials and a filter plate for secondary screening of the materials after initial screening, thereby separating coarse and fine aggregates. Useless waste leaves through the outer cylinder, coarse aggregates leave through the top of the filter plate, and fine aggregates fall onto the conveyor belt. The separation of coarse and fine aggregates is completed during the screening process, improving the efficiency of the entire process. Attached Figure Description

A fixing rod is fixed on the outer surface of the connecting rod 307. The fixing rod is fixed to the screen cylinder 301. The drive motor 305 can drive the connecting rod 307 to rotate, which in turn drives the fixing rod to rotate, thereby driving the screen cylinder 301 to rotate. A feed pipe 308 is installed on the side of the outer cylinder 2. Multiple baffles 309 are fixed on the inner wall of the screen cylinder 301. The crushed concrete material can enter the screen cylinder 301 through the feed pipe 308. The baffles 309 can block the material and prevent the material from leaving the screen cylinder 301 before it is fully screened.

[0030] Please refer to this carefully. Figure 2 , Figure 3 , Figure 4 and Figure 5The screening device 3 also includes two support plates 310 fixed to the inner wall of the box 1. A filter plate 311 is slidably connected to the upper surface of the two support plates 310. The filter port size of the filter plate 311 is smaller than the filter port size of the screen cylinder 301. The material can be screened twice through the filter plate 311. A conveyor belt 4 is installed on the inner wall of the box 1. An auxiliary device 5 is provided on the outer side of the box 1.
