Description

Technical Field

[0001] This utility model relates to the technical field of waste catalyst treatment devices, specifically a waste catalyst pyrolysis tail gas incineration treatment device. Background Technology

[0002] A spent catalyst treatment unit is a specialized device for processing spent catalysts. It typically employs advanced technologies and processes to recycle, regenerate, or safely dispose of spent catalysts. The purpose of this unit is to reduce environmental pollution from spent catalysts while simultaneously achieving resource reuse. A spent catalyst treatment unit may include multiple stages such as physical separation and high-temperature roasting to remove impurities from the spent catalyst, restore its activity, or extract valuable components. By using a spent catalyst treatment unit, companies can reduce production costs, improve resource utilization efficiency, and contribute to environmental protection and sustainable development.

[0003] Existing waste catalysts still have some drawbacks in practical applications. First, the existing waste catalyst treatment devices on the market inject materials into the furnace by opening the furnace door. If the incinerator is in operation, the incinerator needs to be closed and then the furnace door needs to be opened again to inject materials into the furnace, which greatly affects the working efficiency.

[0019] like Figures 1-4 As shown, this utility model provides a technical solution: a waste catalyst pyrolysis tail gas incineration treatment device includes a support leg 1, an incinerator 2 is fixedly installed on the upper surface of the support leg 1, an exhaust pipe 3 is fixedly installed on the outer wall of the incinerator 2, a furnace door 4 is hinged to the outer wall of the incinerator 2, a motor 5 is fixedly installed on the outer wall of the incinerator 2, a flame nozzle 6 is fixedly installed inside the incinerator 2, a graded feeding mechanism 7 is provided on the outer wall of the incinerator 2, and an evacuation mechanism 8 is provided inside the incinerator 2.

[0020] The aforementioned graded feeding mechanism 7 includes: a feeding trough 701, a rotating rod 702, a large gear 703, a small gear 704, a long rod 705, a baffle 706, a hinge block 707, and a short rod 708. The feeding trough 701 is fixedly installed on the upper surface of the incinerator 2. Two sets of feeding troughs 701 are provided, symmetrically arranged with the vertical centerline of the incinerator 2 as the axis of symmetry, and the internal structure of the two sets of feeding troughs 701 is the same. The rotating rod 702 is rotatably connected to the upper surface of the incinerator 2. A large gear 703 is fixedly installed on the outer wall of the rotating rod 702. The large gear 703 and the small gear 704 are in a meshing state. The small gear 704 is rotatably installed on the upper surface of the incinerator 2. A long rod 705 is hinged to the upper surface of the small gear 704. The inner wall of the feeding trough 701... A baffle 706 is slidably connected, and a hinge block 707 is fixed to the outer wall of the baffle 706. A short rod 708 is hinged to the outer wall of the hinge block 707. One end of the short rod 708 is hinged to the outer wall of the hinge block 707, and the other end of the short rod 708 is hinged to the end of the long rod 705. A pulley is fixedly installed at the output end of the motor 5, and a pulley is fixedly installed on the outer wall of the rotating rod 702. Belts are wound around both sets of pulleys. When the rotating rod 702 rotates, it drives the small gear 704 meshing with the large gear 703 to rotate as well. At this time, the long rod 705 pulls the short rod 708, causing the baffle 706 to slide outward on the inner wall of the feeding trough 701, completing intermittent feeding. It should be noted that the two sets of feeding troughs 701 complete the intermittent feeding operation synchronously.

[0021] The aforementioned evacuation mechanism 8 includes: a disc 801, a rectangular rod 802, a U-shaped rod 803, a fixed rod 804, and rake teeth 805. The disc 801 is fixedly installed on the outer wall of the rotating rod 702. The rectangular rod 802 is hinged to the upper surface of the disc 801. One end of the rectangular rod 802 is hinged to the upper surface of the disc 801, and the other end of the rectangular rod 802 is hinged to the outside of the end of the U-shaped rod 803. The end of the rectangular rod 802 is hinged to the U-shaped rod 803. The fixed rod 804 is installed on the outer wall of the incinerator 2. The U-shaped rod 803 slides on the inner wall of the fixed rod 804. The end of the U-shaped rod 803 is fixedly installed with rake teeth 805. The disc 801 will drive the rectangular rod 802 to pull the rake teeth 805 at the end of the U-shaped rod 803 to evacuate the internal materials and combustion aids, preventing the materials and combustion aids from accumulating together and causing incomplete combustion, which would affect the combustion effect.

[0022] Working principle: The material and combustion aid are poured into two sets of feeding troughs 701 respectively. The motor 5 is started, and the output end of the motor 5 rotates. At the same time, the power is transmitted to the rotating rod 702 by the belt, causing the rotating rod 702 to rotate as well. While the rotating rod 702 is rotating, the small gear 704, which meshes with the large gear 703, will also rotate. At this time, the long rod 705 will pull the short rod 708, causing the baffle 706 to slide outward on the inner wall of the feeding trough 701, completing the intermittent feeding. It should be noted that the two sets of feeding troughs 701 complete the intermittent feeding operation synchronously. When the material and combustion aid fall into the interior of the incinerator 2, the flame nozzle 6 is opened to ignite the combustion aid and material. While the rotating rod 702 is rotating, the disc 801 on the outer wall of the rotating rod 702 will drive the rectangular rod 802 to pull the rake teeth 805 at the end of the U-shaped rod 803 to disperse the material and combustion aid inside, preventing the material and combustion aid from accumulating together and causing incomplete combustion, which would affect the burning effect.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
