Description

Technical Field

[0001] This invention relates to the field of solid waste treatment technology, and in particular to a dual-power continuous mixing device. Background Technology

[0002] The granular materials formed from the fine processing of construction solid waste require precise metering and mixing with added chemicals and an appropriate amount of water to produce recycled building materials and achieve the goal of solid waste resource utilization. Currently, commonly used metering and mixing equipment employs a weighing system to separately measure the chemicals and materials, followed by uniform mixing in a stirring device. After mixing, the material must be discharged before the next batch can be processed, representing an intermittent production method. Although some continuous metering and mixing systems exist for continuous mixing of materials with low moisture content, they often struggle to maintain stable production and exhibit poor mixing uniformity when processing finished materials with high moisture content after mixing. Furthermore, it is difficult to produce finished materials on demand. Summary of the Invention

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0021] See attached document Figure 2 This invention provides a dual-power continuous mixing device, including a screw feeding mechanism 1, the discharge end of which is connected to a mixing cylinder 2, as shown in the attached figure. Figure 3A mixing shaft 3 is rotatably installed inside the mixing cylinder 2. A throwing turbine 4 is fixed at the front end of the mixing shaft 3. The throwing turbine 4 is used to throw the material conveyed by the screw feeding mechanism 1 into the mixing zone inside the mixing cylinder 2. A drug injection pipe 5 is provided above the mixing zone of the mixing cylinder 2. The drug injection pipe 5 is used to spray the drug (a mixture of powder and water) onto the material in the mixing zone. An air self-suction hole 51 is provided at the liquid outlet end of the drug injection pipe 5. An agitator 6 is fixed behind the throwing turbine 4 on the mixing shaft 3. In this invention, the screw feeding mechanism 1 uniformly conveys the material to the throwing turbine 4. The rotating throwing turbine 4 throws the material into the mixing zone. At the same time, the drug conveyed by the drug injection pipe 5 draws in external air when it passes through the air self-suction hole 51, which can increase the diffusion degree of the drug during spraying. The dispersed material in the mixing zone meets the dispersed drug to form a mixture. The mixture has a good mixing effect. Then, the rotating agitator 6 agitates at high speed and conveys the mixture to the outlet 21 of the mixing cylinder 2 while agitating. In this invention, the screw feeding mechanism 1 provides uniform feeding, the throwing turbine 4 and the agent injection pipe 5 mix the dispersed agent with the dispersed material, resulting in a good mixing effect. The stirring wheel 6 further stirs the material and agent to achieve full mixing. The three work together to complete the continuous mixing and conveying of solid material and agent. Secondly, the screw feeding mechanism 1 and the mixing shaft 3 are powered separately, so a high-speed mixing shaft 3 can be set to improve the mixing efficiency.

[0022] As another embodiment of the present invention: refer to the appendix Figure 6 The material-throwing turbine 4 includes a hub 41, blades 42, and a support ring 43. The hub 41 is fixed on the mixing shaft 3, and the blades 42 are fixed between the hub 41 and the support ring 43. The support ring 43 is rotatably disposed inside the mixing cylinder 2, and the blades 42 are inclined. The high-speed rotating blades 42 throw the material fed by the screw feeder 1 into the mixing zone, where it mixes with the agent sprayed in the mixing zone.

[0023] As another embodiment of the present invention: refer to the appendix Figure 5 Part of the stirring wheel 6 is located within the mixing zone. The throwing turbine 4 and the agent injection pipe 5 mix the dispersed agent with the dispersed material in the mixing zone, and then the stirring wheel 6 further agitates and mixes the materials.

[0024] In another embodiment of the present invention, the stirring wheel 6 includes multiple stirring blades, each blade comprising a rectangular frame 61 and a stirring plate 62. The rectangular frame 61 and the stirring plate 62 are vertically arranged. The stirring plate 62 has a rhomboid cross-section and is inclined, with the inclination direction of the stirring plate 62 being the same as that of the blades 42. The stirring wheel 6 mixes the materials, while the inclined stirring plate 62 conveys the materials backward.

[0025] Specifically, the tilt angle of the stirring plate 62 is smaller than the tilt angle of the blade 42.

[0026] In another embodiment of the present invention, this embodiment further includes a feed hopper 7, with a screw feeding mechanism 1 located below the feed hopper 7. The feed hopper 7 is used to store crushed and refined materials, which can be provided by a crusher. The screw feeding mechanism 1 conveys the crushed and refined materials. After being thrown by the throwing turbine 4, the crushed and refined materials are well dispersed, reducing the occurrence of clumps and improving the mixing effect between the materials and the reagents.

[0027] As another embodiment of the present invention: refer to the appendix Figure 1 and attached Figure 3 The spiral feeding mechanism 1 includes spiral blades 11. A pusher cylinder 8 is provided between the feed hopper 7 and the mixing cylinder 2. The rear end of the spiral blades 11 extends into the pusher cylinder 8, and the orifice of the pusher cylinder 8 is adapted to the diameter of the spiral blades 11. The spiral blades 11 convey the solid material from the feed hopper 7 to the pusher cylinder 8, and the rotating throwing turbine 4 throws the material in the pusher cylinder 8 into the mixing zone. The spiral blades 11 rotate at a slow speed, while the blades 42 rotate at a fast speed. This design of slow speed at the front and fast speed at the back facilitates the throwing of the material conveyed by the spiral blades 11 by the blades 42.

[0028] As another embodiment of the present invention: refer to the appendix Figure 4 The agent injection pipe 5 is provided with a beam section 52, a straight pipe section 53, and an expansion section 54 in sequence along its conveying direction. Air self-priming holes 51 are located on the straight pipe section 53. The smaller ends of the beam section 52 and the expansion section 54 are positioned facing each other. The air self-priming holes 51 are obliquely distributed, with their inlets close to the beam section 52 (i.e., the inlet is above the outlet). As the mixture passes through the beam section 52, its aperture gradually decreases, and its flow velocity increases. Passing through the straight pipe section 53, it can draw in more air to mix with the mixture. Then, through the expansion section 54, the air-infused mixture is sprayed more dispersed, further improving the mixing effect with the solid material.

[0029] As another embodiment of the present invention: refer to the appendix Figure 3 The discharge end of the agent injection pipe 5 is inclined, and the outlet of the agent injection pipe 5 faces the throwing turbine 4. This structural design facilitates the spraying of the agent onto the thrown crushed and refined material, allowing the two to be fully mixed.

[0030] In another embodiment of the present invention: the mixing shaft 3 is fixed with a speed-increasing spiral 9 behind the stirring wheel 6. The stirring wheel 6 stirs the mixture and conveys it to the speed-increasing spiral 9. After the mixture is accelerated and pressurized at the speed-increasing spiral 9, it is discharged from the outlet 21.

[0031] In another embodiment of the present invention: a cleaning screw 010 is fixed behind the speed-increasing screw 9 on the mixing shaft 3, and the discharge port 21 of the mixing cylinder 2 is located between the speed-increasing screw 9 and the cleaning screw 010, with the speed-increasing screw 9 and the cleaning screw 010 rotating in opposite directions. The cleaning screw 010 removes residual material from its end, preventing the mixture from accumulating at the end of the mixing cylinder 2.

[0032] In another embodiment of the present invention, the axes of the helical blade 11 and the mixing shaft 3 are the same.

[0033] In another embodiment of the present invention: a throwing cylinder 011 is provided between the pushing cylinder 8 and the mixing cylinder 2, a sealing structure is provided between the throwing cylinder 011 and the pushing cylinder 8, a sealing structure is provided between the throwing cylinder 011 and the mixing cylinder 2, and a support ring 43 is rotatably disposed inside the throwing cylinder 011.

[0034] As another embodiment of the present invention: the spiral blade 11 is connected to the output shaft of the second motor 12, and the second motor 12 is connected to the spiral blade 11 through the belt drive mechanism 13. The second motor 12 is located below the spiral blade 11. This structural design makes the overall structure compact and can effectively reduce the length of the mixing device.

[0035] Specifically, the helical blade 11 is a shaftless helical blade 11.

[0036] In another embodiment of the present invention, the mixing shaft 3 passes through the mixing cylinder 2 and is connected to the first motor 012 via a belt drive mechanism 13. The first motor 012 is located on one side of the mixing cylinder 2. This structural design makes the overall structure compact and can effectively reduce the length of the mixing device.

[0037] In this invention, the spiral feeding mechanism 1 conveys the material to the throwing turbine 4, and the rotating throwing turbine 4 throws the material into the mixing zone. Simultaneously, the agent sprayed by the agent injection pipe 5 draws in external air as it passes through the air self-suction hole 51, further increasing the diffusion degree of the agent during spraying. The dispersed material in the mixing zone mixes with the dispersed agent to obtain a mixture with good mixing effect. The rotating stirring wheel 6 simultaneously stirs and conveys the mixture to the outlet 21 of the mixing cylinder 2. In this invention, the spiral feeding mechanism 1 uniformly conveys solid material, and the agent injection pipe 5 conveys the agent; the throwing turbine 4 and the agent injection pipe 5 mix the dispersed agent and dispersed material in the mixing zone, resulting in good mixing effect; the initially mixed material is further mixed by the stirring wheel 6. The three mechanisms work together to achieve continuous mixing and conveying of solid material and agent. Furthermore, the feeding speed of the spiral feeding mechanism 1 and the rotation speed of the mixing shaft 3 are set separately, allowing for a high-speed mixing shaft 3 to improve mixing efficiency.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
