Description

Technical Field

[0001] The present invention relates to waste treatment, and more particularly to an integrated device and method for separating the barrel and the material and crushing the material of a hazardous waste material storage barrel. Background Art

[0002] Hazardous waste materials are usually transported to a hazardous waste treatment plant for treatment in a hazardous waste material storage barrel. Due to the presence of highly active solid-liquid mixed materials in the hazardous waste materials, the hazardous waste material storage barrels containing such hazardous waste materials cannot be broken manually. And this type of hazardous waste material needs to go through pretreatment processes such as water washing and deactivation before incineration. Therefore, it is necessary to quickly separate the barrel from the material. At the same time, the traditional crushers in hazardous waste treatment plants cannot achieve the separation of the barrel and the material of the hazardous waste material storage barrel. On the one hand, this reduces the efficiency of the water washing pretreatment. On the other hand, due to the long cycle, there is a risk of reaction heat release.

[0003] Therefore, it is necessary to propose an integrated device and method for separating the barrel and the material and crushing the material of a hazardous waste material storage barrel to solve the problems in the prior art. Summary of the Invention

[0044] Hazardous waste materials are usually transported to a hazardous waste treatment plant for treatment using hazardous waste material storage barrels. Due to the presence of highly active solid-liquid mixed materials in the hazardous waste materials, the hazardous waste material storage barrels containing such hazardous waste materials cannot be broken manually. And this type of hazardous waste materials needs to undergo pretreatment processes such as water washing and deactivation before incineration. Therefore, it is necessary to quickly separate the barrel and the materials. At the same time, the traditional crushers in hazardous waste treatment plants cannot achieve the separation of the barrel and materials of the hazardous waste material storage barrel, which on the one hand reduces the efficiency of the water washing pretreatment, and on the other hand, due to the long cycle, it will cause the risk of reaction heat release.

[0045] Embodiment 1

[0046] To solve the technical problems in the prior art, the present invention provides an integrated device for separating the barrel and materials of a hazardous waste material storage barrel and crushing the materials, including:

[0047] A barrel-material separation unit for separating the hazardous waste material storage barrel from the hazardous waste materials located inside the barrel;

[0048] A material crushing unit for crushing the hazardous waste materials;

[0049] Among them, the barrel and material separation unit includes:

[0050] A lid cutting device that cuts off the lids at both ends of the hazardous waste material storage barrel; and

[0051] A material pushing device for pushing the hazardous waste material out from one end of the hazardous waste material storage barrel after being processed by the lid cutting device.

[0052] Next, refer to Figure 1 and Figure 2 for an exemplary description of an integrated device for separating the barrel and material and crushing the material of a hazardous waste material storage barrel proposed by the present invention. Among them, Figure 1 FIG. is a schematic structural diagram of an integrated device for separating the barrel and material and crushing the material of a hazardous waste material storage barrel according to an embodiment of the present invention; Figure 2 is according to Figure 1 A schematic structural diagram of an integrated device for separating the barrel and material and crushing the material of a hazardous waste material storage barrel observed in the direction of arrow B in

[0053] The integrated device for separating the barrel and material and crushing the material of a hazardous waste material storage barrel includes a barrel and material separation unit 1 and a material crushing unit 2. The barrel and material separation unit 1 is used to separate the hazardous waste material storage barrel from the hazardous waste material inside the hazardous waste material storage barrel. Among them, the barrel and material separation unit 1 includes a lid cutting device 11 and a material pushing device 12. The lid cutting device 11 is used to cut off the lids at both ends of the hazardous waste material storage barrel, and the material pushing device 12 is used to push the hazardous waste material out from one end of the hazardous waste material storage barrel after being processed by the lid cutting device.

[0054] Refer to Figure 2 , the material pushing device 12 and the material crushing unit 2 are arranged at both ends of the lid cutting device 11. Arranging the material pushing device 12 and the material crushing unit 2 at both ends of the lid cutting device 11 enables the hazardous waste material storage barrel to directly enter the material crushing unit after lid cutting and barrel and material separation to perform crushing treatment on the hazardous waste material, making the treatment process smooth, further reducing the treatment time, and improving the treatment efficiency of the hazardous waste material.

[0055] Exemplarily, the lid cutting device includes a fixing mechanism and a lid cutting blade.

[0056] Refer to Figure 1 and Figure 2, which shows a schematic structural diagram of a fixing mechanism and a cover-cutting blade according to an embodiment of the present invention. The fixing mechanism includes at least two lower driving rollers 1101 arranged in parallel, and at least two upper driving rollers 1102 arranged in parallel directly above the lower driving rollers 1101. The upper driving rollers 1102 correspond to the lower driving rollers 1101 one by one, and the upper driving rollers 1102 can move up and down above the lower driving rollers 1101. The cover-cutting blade 1104 includes rotary blades provided at both ends of the upper driving rollers 1102.

[0057] Exemplarily, the lower driving rollers 1101 and the upper driving rollers 1102 are respectively equipped with motors for rotation.

[0058] Exemplarily, the fixing mechanism further includes a control mechanism 1103 for controlling the up and down movement of the upper driving rollers 1102 above the lower driving rollers 1101. Under the control of the control mechanism 1103, the upper driving rollers 1102 can move up and down above the lower driving rollers 1101.

[0059] As Figure 1 shown, during the use process, first, the control mechanism 1103 raises the upper driving rollers 1102, and sets the distance between the upper driving rollers 1102 and the lower driving rollers 1101 to be larger than the diameter of the hazardous waste material storage barrel. The hazardous waste material storage barrel A is conveyed to the lower driving rollers 1101 through the feed inlet 3 of the integrated device for separating the barrel material and crushing the material of the hazardous waste material storage barrel. By rotating the lower driving rollers 1101, the axial center line of the hazardous waste material storage barrel A is made parallel to the axis of the lower driving rollers 1101. Then, the control mechanism 1103 moves the upper driving rollers 1102 downward. As the upper driving rollers 1102 move downward, they contact the hazardous waste material storage barrel A and further move downward, exerting extrusion on the hazardous waste material storage barrel A. At the same time, the upper and lower driving rollers (1101 and 1102) keep rotating. Therefore, while the hazardous waste material storage barrel A rotates, it is also extruded, and the hazardous waste material inside is preliminarily crushed. The cover-cutting blade 1104 is provided at both ends of the upper driving rollers 1102, so that during the downward movement of the upper driving rollers, the cover-cutting blade 1104 also moves downward. The cover-cutting blade 1104 is set as a rotary blade, so that during the process of preliminarily crushing the material in the hazardous waste material storage barrel A, the barrel cover of the hazardous waste material storage barrel A is cut off by the rotation of the rotary blade. Exemplarily, the feed inlet 3 is set as a ramp inclined downward, so that the hazardous waste material storage barrel A can quickly enter between the lower driving rollers 1101 during the feeding process. Exemplarily, the included angle range between the ramp and the horizontal direction is set to 1° - 10°. In this embodiment, the included angle range between the ramp and the horizontal direction is set to 5°.

[0060] Exemplarily, the integrated device for separating the barrel material and crushing the material of the hazardous waste material storage barrel further includes a push cover mechanism for pushing the cut barrel cover of the hazardous waste material storage barrel off the hazardous waste material storage barrel. Since the barrel covers at both ends of the hazardous waste material storage barrel are cut off, they often cannot fall off automatically due to the adhesion of the hazardous waste material inside the barrel. By setting up the push cover mechanism, it can assist the falling of the barrel cover after cutting the cover, so as to facilitate the smooth progress of the subsequent material pushing process, and realize the complete automation of the cover cutting and material pushing processes in the integrated device for separating the barrel material and crushing the material of the hazardous waste material storage barrel. As Figure 1 shown, the push cover mechanism 1105 is installed on the control mechanism 1103 that controls the up and down movement of the driving roller 1102. The barrel cover pushed off by the push cover mechanism 1105 enters the chute 4 arranged at the bottom of the integrated device for separating the barrel material and crushing the material of the hazardous waste material storage barrel.

[0061] Continuing to refer to Figure 1 and Figure 2 , after cutting off the barrel cover of the hazardous waste material storage barrel A, the material pushing device 12 is used to push the hazardous waste material out of the hazardous waste material storage barrel A from one end of the hazardous waste material storage barrel A. The pushed hazardous waste material enters the shredding unit 2 for crushing. The shredding unit 2 is arranged at the end of the hazardous waste material storage barrel A opposite to the material pushing device 12, so that the hazardous waste material can directly enter the shredding unit only after being pushed out of the hazardous waste material storage barrel A by the material pushing device 12. The whole process is smooth, reducing the time consumed by the intermediate conversion processing unit. The material pushing device 12 can be any rod-shaped or barrel-shaped device with a diameter smaller than the hazardous waste material storage barrel. Exemplarily, as Figure 2 shown, the material pushing device 12 includes a push rod 1201 for moving forward and backward the hazardous waste material in the material pushing device in the hazardous waste material storage barrel A and a push surface 1202 arranged to have an area similar to the cross-sectional area of the hazardous waste material storage barrel A for pushing the hazardous waste material out.

[0062] Exemplarily, the shredding unit 2 includes a crusher 21. The crusher can be any type of crusher used for crushing hazardous waste materials. Exemplarily, the shredding unit 2 further includes a cutting knife 22 arranged above the crusher 21 for pre-crushing the hazardous waste material pushed out of the hazardous waste material storage barrel A by the material pushing device 12, improving the efficiency of the subsequent crushing of the hazardous waste material by the crusher 21. The cutting knife 22 is set as a vertical alloy cutting knife. As Figure 2 shown, it is set as a cutting knife that is located at the end where the hazardous waste material is pushed out of the hazardous waste material storage barrel A, above the crusher 21, and is arranged intermittently.

[0065] Refer to Figure 3 , first, perform step S1: Cut off the barrel covers at both ends of the hazardous waste storage barrel. This step can be carried out using any cover-cutting device. Exemplarily, during the cover-cutting process, it also includes steps of primary crushing of the hazardous waste materials and preliminary separation of the barrel materials. Exemplarily, step S1 includes: S11: Fix the hazardous waste storage barrel; S12: Exert pressure on the hazardous waste storage barrel to perform primary crushing of the hazardous waste materials and preliminary separation of the barrel materials; S13: Cut off the barrel covers at both ends of the hazardous waste storage barrel.

[0066] Exemplarily, use an integrated device for separating the materials in a hazardous waste storage barrel and crushing the materials as described in Embodiment 1. Refer to Figure 1 and Figure 2 , the 200L hazardous waste storage barrel A containing highly active hazardous waste materials is placed into the feed inlet 3 of the integrated device by a forklift; the hazardous waste storage barrel A rolls between the lower driving rollers 1101 on the ramp of the feed inlet 3; start the motor of the lower driving rollers 1101 and rotate for 10 s. At this time, the axis of the hazardous waste storage barrel A is parallel to the axis of the lower driving rollers 1101; while maintaining the rotation of the lower driving rollers 1101, operate the control mechanism 1103 to control the upper driving rollers 1102 to move downward. When reaching a certain position, the hazardous waste storage barrel A is clamped by the two lower driving rollers 1101 and the two upper driving rollers 1102; start the motor of the upper driving rollers 1102 to make the upper driving rollers 1102 rotate. Under the action of the extrusion force, the large pieces of hazardous waste materials in the hazardous waste storage barrel A are crushed, and preliminary separation of the barrel materials is achieved. This process lasts for 15 s.

[0067] Continuously refer to Figure 3 , then, perform step S2: Push out one end of the hazardous waste storage barrel after the hazardous waste materials are processed in step S1.

[0069] Continue to refer to Figure 3 , then, execute step S3: perform crushing treatment on the waste hazardous materials.

[0070] Exemplarily, before performing the crushing treatment on the waste hazardous materials, a step of pre-crushing the waste hazardous materials is further included. Continue to refer to Figure 1 and Figure 2 , the integrated device for separating barrel and material and crushing waste hazardous materials according to an embodiment of the present invention is used to execute step S2. After the material pushing device 12 pushes the waste hazardous materials from one end of the waste hazardous material storage barrel A to the other end of the waste hazardous material storage barrel A, the waste hazardous materials are pre-crushed by the cutting knife 22 provided at the other end of the waste hazardous material storage barrel A and then enter the crusher 21 for crushing. The crusher 21 operates for 5 minutes. The average particle size of the crushed waste is less than 50 mm.
