[0036] Embodiment: Please refer to Appendix Figure 1 to Appendix Figure 10 :

[0037] The present invention provides a harmful substance treatment device for preparing concrete based on construction waste recycling, including: a support assembly 1; the support assembly 1 includes a base 11, a connecting frame 12 and a support plate 13. A clamping shaft 1101 is fixedly welded on the inner side surface of the base 11. The connecting frame 12 is rotatably clamped on the clamping shaft 1101, and the bottom of the connecting frame 12 is fixedly connected to the support plate 13; a stirring tank 3 is clamped inside the connecting frame 12; a support rod assembly 2 is clamped inside the support plate 13; a treatment box 4 is installed on the top surface of the stirring tank 3; a compartment 401 is opened inside the treatment box 4, and a driving component 7 is installed in the compartment 401; the driving component 7 includes a mounting plate 71 and a driving motor 72. The driving motor 72 is installed inside the mounting plate 71, and the driving shaft of the driving motor 72 is coaxially connected to a rotating part 6; an electric control telescopic rod 5 is fixedly connected inside the rotating part 6.

[0038] In the embodiment of the present disclosure, as shown in Appendix Figure 1 and Appendix Figure 4 shown, the support assembly 1 further includes a hydraulic cylinder 14. The bottom end of the hydraulic cylinder 14 is rotatably connected to the top surface of the base 11 through a shaft. The top end of the push rod of the hydraulic cylinder 14 is sleeved on the clamping rod 1202 through a welding ring. When the hydraulic cylinder 14 is started through an external circuit control terminal, the push rod extends, pushing the connecting frame 12 to rotate around the clamping shaft 1101, and also driving the support plate 13 to rotate, so as to complete the rotational drive of the stirring tank 3, which is convenient for stirring and mixing and also convenient for discharging materials.

[0039] In the embodiment of the present disclosure, as shown in Appendix Figure 2 shown, the stirring tank 3 is composed of a tank body 31 and a tank door 32. Two rectangular holes are opened on the top surface of the tank body 31. A spiral blade 3101 is installed inside the tank body 31. The spiral blade 3101 is connected to the driving shaft of the motor on the connecting plate 1302. An outstanding annular plate is welded on the outside of the tank body 31, and the annular plate is clamped inside the clamping ring cover 1201. The tank door 32 is connected to the front end surface of the tank body 31 through an electric control rotating ring. When the connecting frame 12 rotates, the tank body 31 will be driven to rotate through the clamping ring cover 1201. After the tank door 32 is in the low position state, the tank door 32 is driven to open through the electric control rotating ring, so as to facilitate discharging materials and uniformly treating harmful substances.

[0040] In the embodiments of the present disclosure, as shown in the attached Figure 6 As shown, on both sides of the rotating member 6, there are welded baffle plates 601. At the top of the baffle plates 601, there are welded limit rods 602. The limit rods 602 are clamped in the annular groove 403. After the rotating member 6 rotates driven by the drive shaft of the drive motor 72, the baffle plates 601 are synchronously driven to rotate. The limit rods 602 slide in the annular groove 403 to stabilize the rotation trajectory of the baffle plates 601 without affecting the rotation speed. The concave arc surface structure of the baffle plates 601 can generate a flow velocity difference between the baffle plates 601 and the external air of the processing box 4 during rotation, thereby generating a negative pressure to adsorb harmful substances such as dust into the processing box 4. Thus, during the concrete preparation process, during the feeding stage, harmful substances such as dust raised between the aggregate and other substances made of construction waste and the feed hopper can be processed.

[0041] In the embodiments of the present disclosure, as shown in the attached Figure 3 and the attached Figure 4 As shown, on the top surface of the connecting frame 12, there is fixedly welded a snap ring cover 1201. The snap ring cover 1201 is of a semi-circular structure. On the outer end surface of the connecting frame 12, there is welded a snap rod 1202. Inside the support plate 13, there is a chute 1301. The opening widths on the upper and lower sides of the chute 1301 are greater than the opening width of the middle section. On the top surface of the support plate 13, there is fixedly welded a connecting plate 1302. A motor is installed on the connecting plate 1302, which can drive the spiral blade 3101 inside the mixing tank 3 to rotate, thereby mixing harmful substances such as dust sucked into the mixing tank 3.

[0042] In the embodiments of the present disclosure, as shown in the attached Figure 4 and the attached Figure 5 As shown, inside the processing box 4, there is a water tank 402. An electric control spray head is installed inside the processing box 4. The electric control spray head is connected to the water tank 402 through a pipeline, and the top of the water tank 402 is connected to an external water source through a pipeline. On the bottom surface of the inner top plate of the processing box 4, there is an annular groove 403. The water tank 402 can be used to connect the external water source to the processing box 4. Through the external circuit control terminal, the electric control spray head can be started to spray the water in the water tank 402, thereby performing dust reduction treatment on harmful substances such as dust and sucking them into the mixing tank 3, and the baffle plates 601 can also be cleaned.

[0043] In the embodiments of the present disclosure, as shown in the attached Figure 6 As shown, on the bottom surface of the moving end of the electric control telescopic rod 5, there is fixedly connected a blocking block 501. The blocking block 501 is clamped in the rectangular hole on the top surface of the tank body 31. After the electric control telescopic rod 5 is started through the external circuit control terminal, the moving end drives the blocking block 501 to move, thereby controlling the sealing or opening of the blocking block 501 and the rectangular hole at the top of the tank body 31. In the open state, harmful substances such as dust can be put into the tank body 31. In the sealed state, the mixing substances inside the tank body 31 can be stirred and mixed by the spiral blade 3101.

[0044] In an embodiment of the present disclosure, as shown in the attached Figure 9 figure, the support rod assembly 2 includes a slider 21 and a telescopic rod 22. A fixed shaft 2101 is welded to the bottom surface of the slider 21, and two snap rings 2102 are welded to the outer wall of the slider 21. The snap rings 2102 are respectively clamped on the upper and lower sides of the chute 1301. The top end of the telescopic rod 22 is rotatably connected to the fixed shaft 2101, and the bottom of the telescopic rod 22 is fixedly connected to the top surface of the base 11 by bolts. When the support plate 13 rotates, it presses the telescopic rod 22 to close, completing the rotation of the mixing tank 3, realizing the full mixing of harmful substances such as dust inside the mixing tank 3. The slider 21 can satisfy the relative sliding between the telescopic rod 22 and the support plate 13, and at the same time play a supporting role for the support plate 13.

[0045] In an embodiment of the present disclosure, as shown in the attached Figure 10 figure, the driving component 7 further includes a transmission belt 73. There are two groups of mounting plates 71. A collar 7101 is welded between the two groups of mounting plates 71. The driving motor 72 is installed inside the collar 7101. The driving shaft of the driving motor 72 is connected to the transmission belt 73, and the other end of the transmission belt 73 is connected to another rotating part 6. When the driving motor 72 is started through an external circuit control terminal, the two rotating parts 6 can be synchronously rotated through the transmission belt 73, so that the two processing boxes 4 can simultaneously adsorb harmful substances such as dust raised when the aggregate and sand and gravel are put in.

[0046] Harmful substance treatment method for preparing concrete based on construction waste recycling:

[0047] First, place the support assembly 1 on both sides of the concrete preparation tank, and the processing boxes 4 are located on both sides of the feeding hopper. Start the driving motor 72 to drive the two rotating parts 6 to rotate through the transmission belt 73. At the same time, retract the electric control telescopic rod 5 to make the plug block 501 disengage from the rectangular hole of the tank body 31. The harmful substances such as dust raised between the aggregate and sand and gravel made of construction waste and the feeding hopper during feeding are adsorbed into the processing box 4 through the negative pressure generated by the rotation of the baffle 601. The water in the water tank 402 can be sprayed out by starting the electric control spray head through the external circuit control terminal, so as to carry out dust reduction treatment on the harmful substances such as dust.

[0048] The motor installed on the connecting plate 1302 drives the spiral blade 3101 inside the mixing tank 3 to rotate, so as to mix the harmful substances such as dust sucked into the mixing tank 3. While assisting in the preparation of concrete, the harmful substances such as raised dust can be treated.
