Description

Technical Field

[0001] The invention relates to the technical field of solid waste treatment, in particular to a solid waste pyrolysis furnace. Background Art

[0002] Solid waste refers to solid and semi-solid waste materials generated by humans in production, consumption, life and other activities, commonly known as "garbage". It mainly includes solid particles, garbage, slag, sludge, discarded products, broken utensils, defective products, animal carcasses, spoiled food, human and animal feces, etc.

[0003] Solid waste pyrolysis is to heat solid waste under oxygen-free or anoxic conditions to decompose it and convert it into storable and easily transportable energy such as gas fuel and fuel oil. This process not only reduces the volume of waste, but also the converted energy products can be further utilized. Compared with traditional incineration treatment, pyrolysis is carried out under oxygen-free or anoxic conditions, and the exhaust volume is less than incineration, so it has less pollution to the environment.

[0004] When using a pyrolysis furnace to process solid waste, since the loading port of the pyrolysis furnace is arranged above the furnace body, it does not have an automatic loading function, which makes it inconvenient to put the waste into the furnace body from the loading port. Usually, an additional loader is required for loading. The internal structure of the loader is complicated, which not only greatly increases the equipment cost, but also increases the maintenance cost. Therefore, a solid waste pyrolysis furnace is proposed to solve the above problems. Summary of the invention

The gear is fixed to the shaft, so that the shaft drives the feed box to rotate through the connecting block and the mounting plate. Then the locking assembly can be triggered, and the inclined part of the connecting cylinder will become a horizontal part, and the original horizontal part will tilt downward, so that the counterweight ball enters another part, thereby pulling the pull rope, so that the pull rope drives the card block to move.

[0040] Solid waste is put into the feed hopper 3, and the loading box 7 is raised by the lifting assembly 5. When it rises to the top, the rotating assembly 6 is used to drive the loading box 7 to rotate. After the loading box 7 rotates counterclockwise, the locking assembly 8 can be triggered to open the loading box 7. The width of the loading box 7 and the box door are both smaller than the diameter of the feed hopper 3. The hinge between the box door and the loading box 7 is located below the loading box 7. When the box door is opened, the box door can be used as a transition plate between the loading box 7 and the feed hopper 3, so that solid waste can enter the feed hopper 3 through the box door. After the discharge is completed, the rotating assembly 6 rotates, and then the lifting assembly 5 descends. A stopper is set at the top of the slide rail 4 facing the loading box 7. The top of the stopper is provided with a rounded corner. The stopper can make the loading box 7 re-engage the box door with the loading box 7 when it falls.

[0043] The first hydraulic push rod 607 is extended and retracted to drive the tooth plate 608 to move. Since the tooth plate 608 is engaged with the gear 609, the gear 609 can be driven to rotate. The gear 609 is fixed to the rotating shaft 604, so that the rotating shaft 604 drives the feeding box 7 to rotate through the connecting block 605 and the mounting plate 606, thereby triggering the locking assembly 8.

[0044] The locking assembly 8 includes a connecting tube 801 fixedly connected to the surface of the feeding box 7, both ends of the connecting tube 801 are closed, one end is horizontal, and the other end is inclined downward. A counterweight ball 802 is movably connected inside the connecting tube 801, and a pull rope 803 is fixedly connected to the surface of the counterweight ball 802. The end of the pull rope 803 away from the counterweight ball 802 bypasses the feeding box 7 and is located on the back of the feeding box 7. A sleeve 804 is fixedly installed on the surface of the feeding box 7. The pull rope 803 is located inside the sleeve 804, one end of the sleeve 804 is open and horizontally oriented, and the other end is vertically oriented. The middle section of the connecting tube 801 is curved, and the pull rope 803 moves in the sleeve 804. The sleeve 804 The movement of the pull rope 803 has a corner smoothing effect, the moving direction of the pull rope 803 is guided, and the service life of the pull rope 803 is increased. A connecting plate 805 is fixedly installed on the surface of the loading box 7 and located above the sleeve 804, and a spring 806 is fixedly installed on the top of the connecting plate 805. The top of the spring 806 is fixedly connected to a movable plate 807, and the top of the movable plate 807 is fixedly connected to a clamping block 808. The surface of the loading box 7 is fixedly connected to a clamping plate 809, and the clamping block 808 passes through the interior of the clamping plate 809. A limiting rod 810 is fixedly installed on the bottom of the movable plate 807, and the limiting rod 810 passes through and extends to the bottom of the connecting plate 805.

[0045] The box door is fixedly connected to the clamping plate 809, and the clamping plate 809 is parallel to the movable plate 807. When the box door is closed, the loading box 7 is in a closed state to prevent waste from leaking out of the loading box 7. Rounded blocks are provided at the corners of the loading box 7, and the pull rope 803 fits with the surface of the rounded blocks. When the pull rope 803 moves around the loading box 7, the rounded blocks can prevent the pull rope 803 from fitting with the corner of the loading box 7, which greatly avoids the friction between the pull rope 803 and the corner of the loading box 7 and increases the service life of the pull rope 803.

[0046] The loading box 7 rotates through the rotating shaft 604.

When the block 808 is separated from the card plate 809, the box door is in a tilted state at this time, and the box door will flip due to gravity, so that the box door will open, allowing the waste to enter the feed hopper 3 through the box door.

[0047] In summary, the solid waste pyrolysis furnace, by putting solid waste into the feed hopper 3, uses the second hydraulic push rod 502 to drive the connecting frame 601 to move up and down as a whole, so that the feeding box 7 rises, and when it rises to the top, the first hydraulic push rod 607 is extended and retracted to drive the tooth plate 608 to move. Since the tooth plate 608 is engaged with the gear 609, it can drive the gear 609 to rotate. The gear 609 is fixed to the rotating shaft 604, so that the rotating shaft 604 drives the feeding box 7 to rotate through the connecting block 605 and the mounting plate 606, and then the locking assembly 8 can be triggered, and the inclined part of the connecting cylinder 801 will become a horizontal part, and the original horizontal part will tilt downward, so that the counterweight ball 802 enters another part, thereby pulling the pull rope 803, so that the pull rope 803 drives the block 808 to move. When the block 808 is separated from the card plate 809, the box door is in a tilted state. Due to gravity, the box door will flip over, so that the box door opens, and the box door can be used as a transition plate between the loading box 7 and the feed hopper 3, so that solid waste can enter the feed hopper 3 through the box door.

[0048] And, after the discharge is completed, the first hydraulic push rod 607 contracts to make the feeding box 7 rotate, and then the second hydraulic push rod 502 contracts to drive the connecting frame 601 to descend as a whole, and a block is provided at the top of the slide rail 4 toward the feeding box 7, and the top of the block is provided with a rounded corner. The block can make the feeding box 7 fall and the box door fit with the feeding box 7 again, which will push the block 808 to move downward. When the card hole of the card plate 809 corresponds to the card block 808, the spring 806 is reset, which will make the block 808 fit with the card plate 809 again.
