[0002] In the manufacturing process of thermal insulation pipes, in order to reduce manufacturing costs and improve the ecology and environment, solid waste such as fly ash or inorganic fiber is usually used as its production raw materials, which is conducive to emission reduction and environmental protection, and can promote the efficient and comprehensive utilization of urban garbage and waste.

[0003] At present, there are methods for manufacturing thermal insulation materials using industrial solid waste, such as a production technology for processing thermal insulation materials using industrial solid waste disclosed in announcement number CN110304892A. This technology includes several steps such as fly ash pretreatment, inorganic fiber pretreatment, adhesive preparation, mixing, foaming, and mold forming.

However, the two conveyor lines increase the factory's floor space. When one raw material is more and the other is less, one processing line will be idle prematurely, resulting in a waste of production resources. For this reason, we provide a solid waste pretreatment device and a treatment method for manufacturing insulation pipes using industrial solid waste. Summary of the invention

[0020] Preferably, a dust collecting duct is provided at the front end of the material discharge seat.

[0021] Preferably, a method for treating a solid waste pretreatment device for manufacturing an insulation pipe using industrial solid waste comprises the following steps:

[0022] Step 1: Pour fly ash or inorganic fiber into the feed hopper through the feeding mechanism. After entering, the stepper motor on the first belt drive cover drives the active shear roller to rotate by utilizing the transmission effect of the transmission belt and the pulley. During the rotation of the active shear roller, the gear meshes with the driven shear roller to crush the incoming material through the opposing extrusion force of the two sets of shear rollers. The crushed material falls to the feeding conveyor;

[0023] Step 2: The servo motor on the feeding conveyor runs, driving the material on the conveyor belt to move to the lower material seat. During the movement, first, multiple groups of lower heating rods and upper heating rods cooperate to dry the upper and lower surfaces of the material. Secondly, the color recognition sensor at one end of the third sealing cover can identify the color of the material. The color recognition sensor has a built-in recognition color range of milky white to gray-black, which corresponds to the conventional color of fly ash. If the detected material is this color, it is predicted to be fly ash. At this time, the color recognition sensor will send a signal to the controller to drive the stepper motor on the second belt drive cover to run, and use the transmission column to drive the screening mechanism with a built-in 50-80 mesh screen drum to rotate to the bottom of the material docking mechanism. Otherwise, it is judged to be inorganic fiber. At this time, the screening mechanism with a built-in 30-60 mesh screen drum is driven to rotate to the bottom of the material docking mechanism.

[0024] Step 3: After the screening mechanism arrives at the location, the first hydraulic cylinder on the unloading docking mechanism is driven, and with the guidance of the first guide column, the first flexible connection section is driven to extend, so that the rectangular protrusion on the rectangular connection frame is aligned and engaged with the rectangular groove in the rectangular receiving hopper on the screening mechanism, and the second hydraulic cylinder on the unloading conveyor is driven synchronously, and under the guidance of the second guide column, the second flexible connection section is driven to extend, so that the annular groove on the annular joint is engaged with the annular protrusion on the electromagnetic discharge valve, so as to realize the connection between the unloading conveyor, the screening mechanism and the unloading conveyor. At this time, the loading conveyor continues to convey and continuously delivers the material into the screening mechanism;

[0025] Step 4: After the material enters the screening mechanism, it falls into the screen drum. Under the transmission action of the asynchronous motor, the screen drum rotates at high speed, and uses centrifugal force to drive the material that meets the specifications of the screen drum to pass through the screen holes, so that it enters the unloading conveyor from the electromagnetic discharge valve. An electromagnetic three-way valve is installed at the connection between the unloading conveyor and the electromagnetic discharge valve. The electromagnetic three-way valve can recognize the signal according to the color recognition sensor, and transport the material to the first sealing cover or the second sealing cover based on the type of material to achieve classified transportation;

[0026] Step 5: The material in the unloading conveyor moves to the next process under the transmission action of the servo motor and the conveyor belt. During the process, multiple sets of lower heating rods and upper heating rods in the unloading conveyor cooperate to perform secondary drying on the material, which is convenient for subsequent preparation.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] When the present invention is in use, after the material enters the feeding conveyor, the color recognition sensor can identify the color of the material. The color recognition sensor has a built-in recognition color range of milky white to gray-black, which corresponds to the conventional color of fly ash. If the detected material is of this color, it is predicted to be fly ash. At this time, the color recognition sensor will send a signal to the controller to drive the stepper motor on the second belt drive cover to operate, and use the transmission column to drive the screening mechanism with a built-in 50-80 mesh screen cylinder to rotate to the bottom of the unloading docking mechanism. Otherwise, it is judged to be inorganic fiber. At this time, the screening mechanism with a built-in 30-60 mesh screen cylinder is driven to rotate to the bottom of the unloading docking mechanism to meet the screening requirements of different raw materials. This solves the problem that the prior art usually needs to set up two independent processing lines to pre-treat two raw materials separately during pre-treatment, but the two conveyor lines increase the factory floor space. When one raw material is more and the other raw material is less, one processing line will be idle too early, resulting in a waste of production resources.

[0029] After switching the screening mechanism of the present invention, the first hydraulic cylinder on the unloading docking mechanism can cooperate with the guidance of the first guide column to drive the first flexible connecting section to extend, so that the rectangular protrusion on the rectangular connecting frame is aligned and engaged with the rectangular groove in the rectangular receiving hopper on the screening mechanism, and the second hydraulic cylinder on the unloading conveyor is synchronously driven, and under the guidance of the second guide column, the second flexible connecting section is driven to extend, so that the annular groove on the annular joint is engaged with the annular protrusion on the electromagnetic discharge valve, thereby realizing the connection between the unloading conveyor, the screening mechanism and the unloading conveyor, so that the entire pretreatment process is carried out in a closed and sealed environment to avoid dust pollution.

[0030] By installing a lower heating rod between adjacent rollers in a loading conveyor and a unloading conveyor, and arranging an upper heating rod above the lower heating rod, the upper heating rod and the lower heating rod can heat the material from the top and bottom at the same time, so that the material can be dried during the process of loading and unloading to the next process, meeting subsequent preparation requirements and improving production efficiency.

[0058] See also Figure 1-9 A method for treating a solid waste pretreatment device for manufacturing an insulation pipe using industrial solid waste comprises the following steps:

[0059] Step 1: Pour fly ash or inorganic fiber into the feed hopper 11 through the feeding mechanism. After entering, the stepper motor 22 on the first belt drive cover 12 is driven, and the driving shear roller 52 is driven to rotate by the transmission effect of the transmission belt 44 and the pulley. During the rotation of the active shear roller 52, the gear and the driven shear roller 53 are meshed and driven, and the incoming material is crushed by the opposing extrusion force of the two sets of shear rollers. The crushed material falls to the feeding conveyor 8;

[0060] Step 2: The servo motor 2 on the feeding conveyor 8 runs, driving the material on the conveyor belt 47 to move to the lower material seat 15. During the movement, firstly, multiple groups of lower heating rods 49 and upper heating rods 50 cooperate to dry the upper and lower surfaces of the material. Secondly, the color recognition sensor 13 at one end of the third sealing cover 9 can identify the color of the material. The color recognition sensor 13 has a built-in recognition color range of milky white to grayish black, which corresponds to the conventional color of fly ash. If the detected material is this color, it is predicted to be fly ash. At this time, the color recognition sensor 13 will send a signal to the controller to drive the stepper motor 22 on the second belt drive cover 20 to run, and use the transmission column 19 to drive the screening mechanism 17 with a built-in 50-80 mesh screen drum 32 to rotate to the bottom of the material docking mechanism 16. Otherwise, it is judged to be inorganic fiber. At this time, the screening mechanism 17 with a built-in 30-60 mesh screen drum 32 is driven to rotate to the bottom of the material docking mechanism 16;

[0061] Step 3: After the screening mechanism 17 reaches the position, the first hydraulic cylinder 167 on the unloading docking mechanism 16 is driven, and with the guidance of the first guide column 166, the first flexible connecting section 162 is driven to extend, so that the rectangular protrusion 164 on the rectangular connecting frame 163 is aligned and engaged with the rectangular groove 173 in the rectangular receiving hopper 172 on the screening mechanism 17, and the second hydraulic cylinder 38 on the unloading conveyor 1 is synchronously driven, and under the guidance of the second guide column 40, the second flexible connecting section 35 is driven to extend, so that the annular groove 37 on the annular joint 36 is engaged with the annular protrusion 178 on the electromagnetic discharge valve 177, so as to realize the connection between the unloading conveyor 1, the screening mechanism 17 and the unloading conveyor 1. At this time, the loading conveyor 8 continues to convey and continuously feeds the material into the screening mechanism 17;

[0062] Step 4: After the material enters the screening mechanism 17, it falls into the screen drum 32. Under the driving action of the asynchronous motor 29, the screen drum 32 rotates at a high speed, and uses centrifugal force to drive the material that meets the specifications of the screen drum 32 to pass through the screen holes, so that it enters the unloading conveyor 1 from the electromagnetic discharge valve 177. The electromagnetic three-way valve 34 is installed at the connection between the unloading conveyor 1 and the electromagnetic discharge valve 177. The electromagnetic three-way valve 34 can recognize the signal according to the color recognition sensor 13, and transport the material to the first sealing cover 3 or the second sealing cover 4 based on the type of material to achieve classified transportation;

[0063] Step 5: The material in the unloading conveyor 1 moves to the next process under the transmission action of the servo motor 2 and the conveyor belt 47. During the process, the multiple groups of lower heating rods 49 and upper heating rods 50 in the unloading conveyor 1 cooperate to perform secondary drying treatment on the material, which is convenient for subsequent preparation.
