With the opening of the bags, the waste materials can then be fed for solidification and stabilization treatment. However, in the above patent, the waste materials with bags cannot be automatically opened and fed. Summary of the Invention

[0005] This application aims to at least solve one of the technical problems in the prior art that the waste materials with bags cannot be automatically opened and fed. For this reason, this application proposes a device for solidifying and stabilizing hazardous waste disposal.

[0006] According to an embodiment of this application, a device for solidifying and stabilizing hazardous waste disposal includes a feeding machine.

[0007] At the upper opening of the feeding machine, there is a machine shell. On the opposite inner walls of the machine shell, two groups of partition plates are symmetrically arranged. In the cavity area between the two groups of partition plates, a limiting block is provided, and conveying wheels are respectively arranged on both sides of it. The outer circumferential surfaces of the two groups of conveying wheels are sleeved with a conveyor belt for conveying bagged materials.

[0008] Furthermore, the surface of the conveyor belt is equidistantly penetrated with retractable holes. At the same time, on the inner ring wall surface of the conveyor belt, springs corresponding to the retractable holes are fixedly arranged. At the same time, a retractable and movable plug post is arranged inside the spring. One end of the plug post is in a pointed shape to facilitate insertion into the bagged materials.

[0009] Further, a first crown gear that can rotate synchronously with the conveying wheel is provided downward at the bottom of the conveying wheel. Rotatable second drive shafts are respectively provided on both sides of the bottom of the machine housing. A second gear that can mesh and drive with the first crown gear is fixedly provided at one end of the second drive shaft, and a second crown gear is fixedly provided at the other end of the second drive shaft.

[0010] Further, a first drive shaft is provided between the second crown gears. First gears that can mesh and drive with the second crown gears are respectively fixedly provided at both ends of the first drive shaft, and a cutting knife for cutting the surface of the bagged material is provided in the middle of the first drive shaft.

[0011] Further, a guide groove is recessed inward on the outer peripheral surface of the limiting block, and racks are respectively provided on the front and back sides of the horizontal sections of the two groups of opposite guide grooves.

[0012] Further, a rotating ring is fixedly provided at the end of the spring, and a third gear that can rotate through the rotating ring is provided at the end of the plug post. The third gear can be meshed and connected with the rack. A cross bar is provided at the relative position of the opening of the rotating ring. At the same time, a threaded rod extends from the surface of the cross bar into the plug post.

[0013] Further, limiting strips are provided on the upper and lower end faces of the inner ring wall of the plug post. At the same time, a moving ring is coaxially provided inside the plug post. A threaded hole that can cooperate with the threaded rod is penetrated at the center of the surface of the moving ring. Ventilation holes for allowing gas to enter are penetrated on the surface of the moving ring. A one-way valve for forming a one-way gas flow is provided on the surface of the moving ring near the tip of the plug post.

[0014] Further, an exhaust hole is extended inward from the outer peripheral surface of the tip of the plug post to the inside, and the exhaust hole is arranged in an inclined structure. At the same time, the opening of the exhaust hole faces the tail end of the plug post.

[0015] Further, the limiting block bulges forward, and both ends are provided with gentle slope structures.

[0016] Further, a conveyor for loading bagged waste is provided on one side of the upper end of the feeding machine. An outlet slot for sending out the packaging bag is penetrated on one side of the outer surface of the machine housing.

[0017] The beneficial effects of the present application are as follows: When the bagged materials need to be processed, the materials can be placed above the conveyor at this time. Subsequently, the materials move between the two conveyor belts. At the same time, with the rotation of the conveyor belts, the insertion posts can extend from the telescopic holes through the limit blocks, and then penetrate into the interior of the bagged materials. Then, through the rotating cutting knife, the bottom of the bagged materials moving forward through the conveyor belts can be cut open, facilitating the rapid discharging of the materials. At the same time, as the tip of the insertion post penetrates into the interior of the bagged materials, and the gear three provided at the end of the insertion post can form a meshing connection with the rack. As the insertion post continuously moves to one side, the moving ring will drive the one-way valve to move towards the exhaust hole, and then the gas inside the insertion post will be squeezed out in the direction of the exhaust hole, facilitating the discharge of the residual waste on both sides of the bagged materials. Finally, when the conveying wheel rotates, the gear four can accelerate the rotation of the gear five. With the rotation of the gear five, the crown gear three can rotate together. After the crown gear three rotates, the paddle can rotate together at an accelerated speed through the rotating shaft two. With the rotation of the paddle, the air flow can be discharged through the air duct. At the same time, when the packaging bag is conveyed between the two exhaust pipes through the insertion post, and is conveyed forward with the retraction of the insertion post and the rotation of the bonding block, the packaging bag can be discharged from the discharge chute. And with the air duct opened in the lower exhaust pipe, the upward discharged gas can enter the interior of the open packaging bag, and then the residual waste can be cleaned again.

[0043] The following describes a hazardous waste solidification and stabilization disposal device according to an embodiment of the present application with reference to the accompanying drawings.

[0044] As Figure 1 shown, a hazardous waste solidification and stabilization disposal device according to an embodiment of the present application includes: a feeder 1 for feeding waste, the feeder 1 is provided with a structure with an open lower end, and a conveyor 2 for loading bagged waste is provided on one side of the upper end of the feeder 1. Through the conveyor 2, the bagged material can be placed on the surface and then conveyed upward into the feeder 1 to facilitate subsequent treatment of the waste.

[0045] Meanwhile, a casing 3 is provided at the upper opening of the feeder 1. Opposite inner walls of the casing 3 are symmetrically provided with partitions 31 parallel to the conveyor 2. The partitions 31 are arranged in two groups opposite to each other up and down, so as to form a relatively independent cavity. An outlet slot 32 for sending out the packaging bag is penetrated and opened on one side of the outer surface of the casing 3.

[0046] As Figures 2 - 9As shown, a limiting block 33 that can restrict the movement path of the insertion post 42 is provided in the cavity area between the two groups of partition plates 31. At the same time, the limiting block 33 protrudes forward, and both ends are provided with gentle slope structures. At the same time, conveying wheels 43 are respectively provided on both sides of the cavity area between the two groups of partition plates 31, and a conveyor belt 4 capable of conveying bagged materials is sleeved on the outer peripheral surfaces of the two groups of conveying wheels 43. The surface of the conveyor belt 4 is equidistantly penetrated with telescopic holes 45 that can be telescoped. The driving of the conveying wheels 43 is completed by power transmission through a motor 41 provided above the partition plate 31. Therefore, when the motor 41 operates, the output end of the motor 41 can make the conveying wheels 43 rotate.

[0047] At the same time, a spring 46 corresponding to the telescopic hole 45 is fixedly provided on the inner ring wall surface of the conveyor belt 4. At the same time, an insertion post 42 that can be telescopically moved is provided inside the spring 46. One end of the insertion post 42 is in a pointed shape to facilitate insertion into the interior of the bagged material. And a first crown gear 431 that can rotate synchronously with it is provided downward at the bottom of the conveying wheel 43.

[0048] Rotatable second transmission shafts 34 are respectively provided on both sides of the bottom of the machine housing 3. And a second gear 341 that can be meshed and driven with the first crown gear 431 is fixedly provided at one end of the second transmission shaft 34 on one side, and a second crown gear 342 is fixedly provided at the other end of the second transmission shaft 34. Therefore, when the conveying wheel 43 rotates, the second gear 341 can be driven through the first crown gear 431 at the bottom of the conveying wheel 43.

[0049] And a first transmission shaft 5 that can be driven by them is provided between the two second crown gears 342. Gear ones 52 that can be meshed and driven with the second crown gears 342 are respectively fixedly provided at both ends of the first transmission shaft 5. And a cutting knife 51 that can cut the surface of the bagged material is provided in the middle of the first transmission shaft 5. Therefore, when the bagged material needs to be processed, the material can be placed above the conveyor 2 at this time. As the conveyor 2 conveys upward, the material can be moved between the two conveyor belts 4. At the same time, under the rotation of the conveyor belt 4, the insertion post 42 can protrude from the telescopic hole 45 through the limiting block 33 and then penetrate into the interior of the bagged material. Subsequently, under the rotation of the conveyor belt 4, the material can continue to be conveyed forward. At the same time, under the rotation of the conveying wheel 43, the first crown gear 431 and the second gear 341 are meshed and connected, and through the transmission of power, the first transmission shaft 5 can rotate together. After the first transmission shaft 5 rotates, the cutting knife 51 provided in the middle can cut open the bottom of the bagged material moving forward through the conveyor belt 4, which can facilitate the material to quickly complete the blanking.

[0050] Such as Figure 5 and Figures 8 - 12As shown, a guide groove 331 is recessed inward on the outer peripheral surface of the limit block 33. Rack teeth 332 are provided on the front and back of the horizontal sections of two groups of opposite guide grooves 331. At the same time, a rotating ring 461 is fixedly provided at the end of the spring 46. At the end of the plug post 42 coaxially arranged inside the spring 46, a third gear 421 is provided which can rotate through the rotating ring 461. The third gear 421 can be meshed and connected with the rack teeth 332. And a cross bar 462 is provided at the opposite position of the opening of the rotating ring 461. At the same time, a threaded rod 463 is extended from the surface of the cross bar 462 into the inside of the plug post 42.

[0051] On the upper and lower end faces of the inner ring wall of the plug post 42, limit bars 422 are provided. At the same time, a moving ring 44 is coaxially arranged inside the plug post 42. A threaded hole 443 which can cooperate with the threaded rod 463 is penetrated through the center of the surface of the moving ring 44. Ventilation holes 441 for allowing gas to enter are penetrated through the surface of the moving ring 44. And a one-way valve 442 for forming a one-way flow of gas is provided on the surface of the moving ring 44 close to the tip of the plug post 42. At the same time, an exhaust hole 423 for exhausting gas is extended inward from the outer peripheral surface of the tip of the plug post 42 to the inside, and the exhaust hole 423 is arranged in an inclined structure, and the opening of the exhaust hole 423 faces the tail end of the plug post 42. When the plug post 42 passes through the front of the limit block 33, at this time, the tip of the plug post 42 can be inserted into the inside of the bagged material. At the same time, the third gear 421 provided at the end of the plug post 42 can be meshed and connected with the rack teeth 332. As the plug post 42 continuously moves to one side, the plug post 42 can continuously rotate. Since the moving ring 44 rotates together with the plug post 42 and the threaded rod 463 is arranged in a fixed structure, the moving ring 44 will drive the one-way valve 442 to move towards the exhaust hole 423, and then the gas inside the plug post 42 will be squeezed out in the direction of the exhaust hole 423 to facilitate the discharge of the waste remaining on both sides of the bagged material. And when the plug post 42 moves to the reverse side of the limit block 33, when the two equal rack teeth 332 are meshed with the third gear 421 again, the moving ring 44 can move away from the exhaust hole 423 in the reverse direction to facilitate the gas to enter again for air supply.

[0052] As Figure 3 and Figures 13 - 14 shown, when the waste inside the bag is fed into the inside of the feeder 1, since the cutting knife 51 only cuts open the bottom surface of the packaging bag, the waste inside the packaging bag is likely to remain. Gear fours 432 are provided opposite to each other on the upper and lower outer peripheral surfaces of the conveying wheel 43. At the same time, on the partition plate 31 at the upper and lower end faces of the conveying wheel 43, a support 311 is extended to one side. One side of the gear four 432 is meshed and connected with a fifth gear 334 which can be accelerated to rotate. The rotation of the fifth gear 334 is connected with the support 311 through a first rotating shaft 333, and then the fifth gear 334 can rotate.

[0053] On one side of each of the two sets of gears five 334, there is a bevel gear three 35 meshed and connected respectively. At the same time, a rotating shaft two 351 extends from the center of the circle between the two opposite bevel gears three 35 towards the center. On one side of the outer peripheral surface of the rotating shaft two 351, there are blades 352 that can accelerate the airflow. A exhaust pipe 36 is sleeved on the outer peripheral surface of the rotating shaft two 351. At the same time, the two opposite exhaust pipes 36 are symmetrically provided with air channels 362 up and down respectively. Rotating grooves 361 are symmetrically opened from the center of the exhaust pipe 36 respectively. On one side of the outer peripheral surface of the rotating shaft two 351, there is a connecting rod 353 corresponding to the rotating groove 361. At the same time, at the end of the connecting rod 353, there is an adhesive block 354 fixed. Therefore, when the conveying wheel 43 rotates, the gear five 334 can be accelerated to rotate through its gear four 432. As the gear five 334 rotates, the bevel gear three 35 can rotate together. After the bevel gear three 35 rotates, the blades 352 can be accelerated to rotate together through the rotating shaft two 351. As the blades 352 rotate, the airflow can be discharged through the air channel 362. At the same time, when the packaging bag is conveyed between the two exhaust pipes 36 through the plug post 42, and with the retraction of the plug post 42 and the rotation of the adhesive block 354 to convey forward, the packaging bag can be discharged from the discharge slot 32. And with the air channel 362 opened in the lower exhaust pipe 36, the gas discharged upward can enter the interior of the open packaging bag, and then the remaining waste can be cleaned again.

[0054] Specifically, the working principle of the hazardous waste solidification and stabilization disposal device: When the bagged material needs to be processed, the material can be placed above the conveyor 2 at this time. As the conveyor 2 conveys upward, the material can be moved between the two conveyor belts 4. At the same time, under the rotation of the conveyor belt 4, the plug post 42 can extend from the telescopic hole 45 through the limit block 33, and then pierce into the interior of the bagged material. Then, under the rotation of the conveyor belt 4, the material can continue to be conveyed forward. At the same time, under the rotation of the conveying wheel 43, the bevel gear one 431 and the gear two 341 are meshed and connected. Through the transmission of power, the drive shaft one 5 can rotate together. After the drive shaft one 5 rotates, the bottom of the bagged material moving forward through the conveyor belt 4 can be cut open by the cutting knife 51 provided in the middle of it, which is convenient for the material to complete the feeding quickly.

[0055] As the tip of the plug post 42 is inserted into the interior of the bagged material, the third gear 421 provided at the end of the plug post 42 can be engaged with the rack 332. As the plug post 42 continuously moves to one side, the plug post 42 can continuously rotate. Since the moving ring 44 rotates together with the plug post 42 and its threaded rod 463 is arranged in a fixed structure, the moving ring 44 will drive the one-way valve 442 to move towards the exhaust hole 423, and then the gas inside the plug post 42 will be squeezed out in the direction of the exhaust hole 423, so as to facilitate the discharge of the residual waste on both sides of the bagged material. And when the plug post 42 moves to the reverse of the limit block 33 and the two equal racks 332 are engaged with the third gear 421 again, the moving ring 44 can move away from the exhaust hole 423 in the reverse direction to facilitate the gas to enter the air supply again.

[0056] And when the conveying wheel 43 rotates, the fourth gear 432 can accelerate the rotation of the fifth gear 334. As the fifth gear 334 rotates, the third crown gear 35 can rotate together. After the third crown gear 35 rotates, the paddle 352 can rotate together at an accelerated speed through the second rotating shaft 351. As the paddle 352 rotates, the air flow can be discharged through the air duct 362. At the same time, when the packaging bag is conveyed to between the two exhaust pipes 36 through the plug post 42, and as the plug post 42 retracts and the bonding block 354 rotates and conveys forward, the packaging bag can be discharged from the discharge chute 32. And with the air duct 362 opened in the lower exhaust pipe 36, the upward discharged gas can enter the interior of the open packaging bag, and then the residual waste can be cleaned again.

[0057] It should be noted that the specific model and specification of the motor 41 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0058] The power supply and principle of the motor 41 are clear to those skilled in the art and will not be elaborated in detail here.
