Technical Field
[0001] This application relates to the field of concrete recycling and treatment technology, specifically a concrete waste recycling and mixing device. Background Technology
[0002] A concrete waste recycling and mixing device is a piece of equipment used to process and recycle concrete waste. This equipment typically includes major components such as a crusher, a screening machine, and a mixer. It is used to crush, screen, and mix concrete waste so that it can be reused in concrete production. This can effectively reduce the environmental pollution caused by concrete waste, save raw material costs, and improve resource utilization.
[0003] According to Chinese Patent Publication No. CN212549807U, a waste concrete residue recycling device for construction engineering includes a base plate. A processing box is fixedly connected to the left side of the upper surface of the base plate, and a dust removal device is fixedly connected to the right side of the upper surface of the base plate. An auxiliary device is inserted into the bottom of the back of the processing box, and a crushing device is fixedly connected to the top of the back of the processing box. Universal wheels are fixedly connected to the four corners of the lower surface of the base plate. A box door is hinged to the bottom of the front of both the processing box and the dust removal device. A box door handle is fixedly connected to the top of the front of the box door. An air outlet pipe is inserted into the bottom of the right side of the dust removal device. A first processing layer is fixedly connected to the bottom of the inner wall of the processing box, and a transition plate is fixedly connected to the middle of the inner wall of the processing box.
[0004] Currently, the process of recycling concrete waste typically involves first crushing the waste, then screening the crushed concrete particles, and finally feeding the screened particles into a concrete mixer for recycling. However, when this waste recycling device is in use, the concrete particles fall to the bottom of the processing tank after crushing and screening. Therefore, it is necessary to remove the screened concrete particles from the tank and feed them into another mixing device for further mixing. This intermediate transfer step is time-consuming and labor-intensive, thus affecting the efficiency of subsequent new concrete production. Therefore, a concrete waste recycling and mixing device is proposed to solve the above problems. Utility Model Content

[0035] Please see Figure 1 and 4The mixing mechanism includes a mixing box 14, a stirring motor 15, a stirring shaft 16, a stirring rod 13, and a discharge pipe 17. The mixing box 14 is fixedly installed at the bottom of the processing box 1. The stirring motor 15 is fixedly installed at the bottom of the mixing box 14. The stirring shaft 16 is fixedly connected to the output shaft of the mixing box 14. The stirring rod 13 is fixedly installed outside the stirring shaft 16. The discharge pipe 17 is fixedly installed through the bottom of the mixing box 14. The bottom of the discharge pipe 17 extends through the bottom of the processing box 1 to the outside. A valve is installed on the discharge pipe 17. A feeding hopper 24 is fixedly installed through the front surface of the processing box 1. One end of the feeding hopper 24 near the processing box 1 is fixedly installed through the inside of the mixing box 14. The feeding hopper 24 is used to add concrete raw materials into the mixing box 14.
[0036] It should be noted that the discharge pipe 17 is used to discharge the mixed concrete. The concrete waste is poured into the treatment box 1 by setting up a crushing mechanism, a screening mechanism and a mixing mechanism. The waste is first crushed by the crushing mechanism. The crushed concrete particles fall onto the screen 12 for screening. The screened concrete particles then fall into the mixing box 14. Concrete raw materials and water are added to the mixing box 14 through the feeding hopper 24 to directly mix and produce new concrete. This device has a high degree of integration and improves production efficiency.
[0037] Please see Figure 1 and 5 In this embodiment, a water storage tank 8 is fixedly installed on the left side of the treatment tank 1. A water inlet pipe 9 is fixedly installed through the top of the water storage tank 8. A pipe cap is threadedly connected to the outside of the water inlet pipe 9. A water pump 10 is fixedly connected to the left side of the water storage tank 8. A water delivery pipe 11 is fixedly connected to the bottom of the water pump 10. The end of the water delivery pipe 11 away from the water pump 10 passes through the treatment tank 1 and is fixed inside the mixing tank 14.

[0039] It is understandable that the collection box 6 is used to collect the concrete waste particles discharged from the treatment box 1, and the support plate 7 is an "L" shaped plate. The collection box 6 has handles fixed on both the front and rear sides. The guide plate 4 is set to guide the material so that the crushed concrete particles fall onto the screen 12.

A connecting block is fixedly connected to the right side of the baffle 18. An electric push rod 5 is fixedly installed on the right side of the processing box 1. The telescopic end of the electric push rod 5 is fixedly connected to the connecting block.
[0041] It is understandable that by setting the baffle 18, the screen 12 blocks the discharge port 20 when screening concrete particles, thereby preventing the particles from being discharged from the discharge port 20 during the screening process. The baffle 18 can be opened and closed by extending and retracting the electric push rod 5.
[0042] The working principle of the above embodiment is as follows: When in use, concrete waste is poured into the feed hopper 2 and crushed by two rotating crushing rollers 3. The crushed concrete particles fall onto the screen 12. Under the action of gravity, the screen 12 slides downward, which squeezes the spring 21 to extend and retract, thereby making the screen 12 slide up and down, which can speed up the screening. The screened concrete particles then fall into the mixing tank 14. Water stored in the water storage tank 8 is pumped into the mixing tank 14 by the water pump 10. Concrete raw materials are then poured into the mixing tank 14 through the feed hopper 24. The stirring motor 15 drives the stirring shaft 16 to rotate and the stirring rod 13 to rotate, which can mix the raw materials to produce new concrete. This device has a high degree of integration and improves production efficiency.
