Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] like Figure 1 , Figure 2 As shown, a pretreatment device for reactive high calorific value viscous materials includes a feeding device 2, an extrusion device, a mixing and stirring device, a discharging device and a material receiving container. By controlling the operation of mechanical equipment and combining the actual conditions of the materials, the incineration materials with reactivity, high viscosity and high calorific value are pretreated, which speeds up the packaging of the materials, thereby reducing labor costs and speeding up the disposal of such difficult-to-handle materials.

[0024] The loading device 2 includes a lifting frame and a cylindrical barrel 1 arranged on the lifting frame. Two grooves are symmetrically arranged on the outer side of the barrel wall of the cylindrical barrel 1, and a bottom cover is hingedly arranged at the bottom of the cylindrical barrel 1. One end of the bottom cover is hinged at the bottom of the cylindrical barrel 1, and the other end is provided with a snap switch. The initial state is: when the cylindrical barrel 1 needs to be loaded with materials, the bottom cover seals the cylindrical barrel 1, and the worker turns off the snap switch of the bottom cover. When the cylindrical barrel 1 is loaded with waste for pretreatment, before lifting, the worker turns on the snap switch, so that when the cylindrical barrel 1 is lifted to the upper part and turned over, the bottom cover can be automatically opened under the action of gravity.

[0025] The lifting frame includes an L-shaped bracket 23, which includes a bottom frame and a side support frame. The bottom frame is surrounded by four angle steels to form a square frame, and the bottom outer edge of the cylindrical barrel 1 is larger than the inner diameter of the square frame, so that the cylindrical barrel 1 can be placed on the bottom frame without falling. A clamping clamp 24 is provided on the side support frame, and the clamping clamp 24 cooperates with the groove on the outer side of the barrel wall of the cylindrical barrel 1.

[0026] A hanging ear 21 is provided at the outer top of the side support frame, and the hanging ear 21 is hung in the buckle 22 of the elevator. The buckle 22 of the elevator is set on the fixed plate 26, and the fixed plate 26 is set on the chain of the elevator; and a hydraulic rod 25 is provided between the fixed plate 26 and the L-shaped bracket 23, one end of the hydraulic rod 25 is hinged on the fixed plate 26, and the other end of the hydraulic rod 25 is hinged on the L-shaped bracket 23.

[0027] During waste treatment, highly reactive, highly viscous, and high calorific value organic hazardous waste has been loaded into the cylindrical barrel 1 in the previous process, and the buckle switch of the bottom cover is closed. In this way, when the cylindrical barrel 1 loaded with waste is placed on the lifting frame, the hanging ear 21 is hooked into the buckle 22 of the elevator, and at the same time, the clamping claw 24 is inserted into the two grooves on the outer side of the barrel wall of the cylindrical barrel 1. Then, the worker opens the buckle switch at the bottom of the cylindrical barrel 1 and lifts the entire feeding device 2 to the feeding position through the elevator 3.

[0028] The hoist 3 comprises a hoisting motor, which drives a transmission sprocket 32 ​​, between which a chain 31 is arranged for transmission, and on which a fixing plate 26 is arranged.

[0029] After the hoist 3 lifts the feeding device 2 to the top, the hydraulic rod 25 on the feeding device 2 is extended to push the feeding device 2 to flip. When flipping, the bottom cover can be automatically opened under the action of gravity, and the material outlet is facing the feeding port 61 of the mixing bin 6. It should be noted that the hydraulic rod 25 is connected to a hydraulic drive device.

[0030] The extrusion device includes: a column 10 arranged on the side of the lifting machine 3, a hydraulic press 5 is arranged on the top of the column 10, and an extrusion plate 51 is arranged at the end of the output rod of the hydraulic press 5. The diameter of the extrusion plate 51 is smaller than the bottom inner diameter of the cylindrical barrel 1, and the position of the extrusion plate 51 is oriented toward the angle position after the cylindrical barrel 1 is turned over. It should be noted that during the initial setting, the staff can adjust the installation position of the hydraulic press 5 according to the angle of the cylindrical barrel 1 after turning over.

[0031] After the feeding device 2 is turned over, the output rod of the hydraulic press 5 extends, and the squeezing plate 51 extends from the bottom frame of the feeding device 2 into the cylindrical barrel 1 (at this time, the bottom cover has been automatically opened), and the squeezing plate 51 squeezes the material in the cylindrical barrel 1 and gradually squeezes the material out of the cylindrical barrel 1. In this way, the squeezing device squeezes the waste out of the cylindrical barrel 1 and enters the feed port 61, and then falls into the mixing bin 6.

[0032] Furthermore, the top edge of the cylindrical barrel 1 is provided with a guide iron plate, which can guide a small amount of liquid flowing out when the waste is turned over into the feed port 61.

[0033] The mixing and stirring device includes a stirring bin 6, a feeding port 61 is arranged at the top of the stirring bin 6, the feeding port 61 is arranged obliquely, the entrance of the feeding port 61 is obliquely upward, and the bottom of the feeding port 61 is connected to the stirring bin 6. A stirring paddle 63 is arranged in the stirring bin 6, and the stirring paddle 63 is driven and connected by a stirring motor 62, and the stirring motor 62 is arranged at the top of the stirring bin 6. After the material falls into the stirring bin, it is stirred and mixed with other pre-added compatible materials to fully and evenly stir the material.

[0034] Preferably, a grid is provided at the entrance of the feed port 61, which prevents the cylindrical barrel 1 from sliding downward and forcibly separates the waste into smaller volumes of waste.

[0035] A discharging device is provided at the bottom of the mixing bin 6, and the discharging device is a spiral discharging device 7, the inlet of the spiral discharging device 7 is located at the bottom of the mixing bin, and the discharging port 72 of the spiral discharging device 7 is provided at the end of the spiral discharging device 7. The material after being stirred and mixed in the mixing bin 6 enters the inlet of the spiral discharging device 7 through the action of the stirring paddle, and is discharged from the discharging port 72 driven by the motor 71 and the screw blades.

[0036] A material receiving container 8 is provided at the bottom of the discharge port 72 of the spiral discharger 7. The material receiving container 8 is a common wide-mouthed plastic barrel. According to the actual situation of the pre-processed material, a 5L, 10L, or 25L plastic barrel can be selected to receive the material. After the loading is completed, the material can be packaged.

[0037] It should be noted that a mixing bin support frame 9 is provided at the bottom of the mixing bin 6 , and the mixing bin support frame 9 raises the position of the mixing bin 6 to a certain height, so that a spiral discharger 7 can be provided below the mixing bin 6 .

[0038] The working principle of the utility model is:

[0039] Highly reactive, highly viscous, and high calorific value organic hazardous wastes are loaded into the cylindrical barrel 1 in advance, and then workers place the cylindrical barrel 1 on the lifting frame of the feeding device 2 by means of a forklift or the like. The workers connect the lifting frame to the hoist 3 and open the bottom cover snap switch at the bottom of the cylindrical barrel 1. The hoist 3 works. When it is lifted to the top, the hydraulic rod 25 works, driving the lifting frame and the cylindrical barrel 1 thereon to flip together. After flipping, the output rod of the hydraulic press 5 extends, and the squeezing plate 51 extends from the bottom frame of the feeding device 2 into the cylindrical barrel 1 (at this time, the bottom cover has been automatically opened). The squeezing plate 51 squeezes the material in the cylindrical barrel 1 and gradually squeezes the material out of the cylindrical barrel 1. Since highly reactive, highly viscous, and high calorific value organic hazardous wastes are semi-solid wastes, it is difficult for them to automatically fall into the mixing bin without external force.

[0040] The waste passes through the extruder and the feed port 61 with a grid and then falls into the mixing bin 6. Conventional materials required for the mixing, such as sawdust to reduce viscosity, activated carbon, and low calorific value sludge, can be put into the mixing bin 6 in advance. After the difficult-to-handle materials are put in, the stirring motor 62 drives the stirring paddle 63 to stir the materials and mix them fully, thereby changing or reducing the reactivity, viscosity and calorific value of the materials, thereby making the material properties milder and more conducive to the feeding and processing after packaging.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that, for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
