Description

Technical Field

[0001] This utility model relates to the technical field of pelletizing equipment based on landfill fly ash treatment, specifically a pelletizing equipment based on landfill fly ash treatment. Background Technology

[0002] Incineration is the main method of municipal solid waste disposal in my country, with advantages such as large processing capacity, significant volume reduction, and resource utilization of thermal energy. However, due to the complex composition of municipal solid waste in my country, the fly ash produced by incineration contains a large number of heavy metal elements and highly toxic organic carcinogens. Fly ash treatment usually adopts melting treatment technology. When using this fly ash treatment technology, it is necessary to use landfill fly ash processing pelletizing equipment to make fly ash pellets.

[0003] For example, Chinese Patent (Announcement No.: CN214639055U) discloses a high-temperature melting and pelletizing device for fly ash from waste incineration, including a trapezoidal support, a first base, a first tilting mechanism, a granulation disc, a rotary drive device, a second base, a second tilting mechanism, a linear drive device, and a sieve plate. The second base is rotatably connected to the waist of the trapezoidal support, and the first base is also tilted. The second tilting mechanism is connected between the lower end of the second base and the bottom surface of the trapezoidal support. The sieve plate is located below the wall of the granulation disc, and the sieve plate is adapted to the contour of the granulation disc wall. A linear drive device is provided on the top surface of the lower end of the second base, and the output end of the linear drive device is connected to the sieve plate to push the sieve plate to extend to the outside of the granulation disc wall. By adding a second base and a sieve to the existing disc granulator, uniformly sized fly ash pellets can be screened out during centrifugal unloading in the granulation disc, improving the functionality of the existing disc granulator, eliminating the need to purchase screening equipment, and reducing costs.

[0004] However, the aforementioned patents still have some shortcomings. The overall structure of their devices is relatively open. When the granulation disc rotates at high speed, the fly ash pellets are easily thrown directly out of the disc, making it difficult to collect the fly ash pellets and causing some inconvenience in use. Therefore, a pelletizing device based on landfill fly ash treatment is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a pelletizing device based on the treatment of fly ash from landfills, which has the advantages of being convenient to use and practical, and solves the problem that the pelletizing devices disclosed in the above-mentioned searched patents are somewhat inconvenient to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pelletizing device based on the treatment of fly ash from landfills, comprising a support base, a support frame installed obliquely on the right side of the support base, an outer shell fixed on the inner wall of the support frame, a motor fixed on the right side of the support frame, a rotating rod fixed on the output shaft of the motor, a pelletizing disc fixed on the outer peripheral wall of the rotating rod, and a discharge mechanism provided on the outer shell;

[0007] The discharge mechanism includes a discharge pipe fixed to the bottom surface of the outer shell, an adjusting rod rotatably connected to the bottom surface of the outer shell, an adjusting plate slidably connected to the outer peripheral wall of the adjusting rod, a plurality of screening tubes fixed to the top surface of the adjusting plate, a screening hole plate fixed to the inner peripheral wall of the screening tubes, and a fixing component provided on the adjusting plate.

[0008] Furthermore, the fixing component includes a threaded ring rotatably connected to the outer peripheral wall of the discharge pipe, a threaded groove adapted to the threaded ring is provided on the outer peripheral wall of the screening pipe, a limit plate is fixed to the bottom end of the adjusting rod, and a spring is fitted on the outer peripheral wall of the adjusting rod.

[0009] Furthermore, the outer shell is a cylindrical hollow shell, the granulation disc is disposed inside the outer shell, and the end of the rotating rod away from the motor is rotatably connected to the inner wall of the outer shell.

[0010] Furthermore, a circular hole is provided on the side of the outer casing facing the motor. The circular hole, the outer casing, the granulation disc, and the rotating rod are all located on the same central axis. The diameter of the circular hole is smaller than the diameter of the granulation disc.

[0011] Furthermore, the adjusting rod is located on the left side of the discharge pipe, and the bottom end of the discharge pipe is inserted into the inside of the screening pipe and fits with it with a gap. The screening plates inside the multiple screening pipes are screening plates with different aperture sizes.

[0012] Furthermore, the adjusting plate is a circular plate, the adjusting rod and the adjusting plate are located on the same central axis, and the plurality of screening tubes are equidistantly distributed along the circumference of the adjusting rod.

[0013] Furthermore, a conical hopper is fixed to the bottom surface of the screening tube, the spring is located at the bottom of the adjusting plate, and the discharge tube is vertically opposite to the rightmost screening tube.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. This pelletizing equipment for treating fly ash from landfills operates by using a motor to rotate a pelletizing disc, which then forms the fly ash into pellets. During pelletizing, the outer shell acts as a shield, preventing the pellets from flying out of the equipment along the inner wall of the pelletizing disc. The outer shell also collects the pellets, facilitating their collection and discharge. Furthermore, the discharge mechanism uses a discharge pipe in conjunction with a screening pipe to screen the pellets, improving the pelletizing quality.

[0016] 2. This pelletizing equipment based on the treatment of fly ash from landfills has multiple screening tubes with different aperture diameters inside. During use, the different screening tubes can be matched with the discharge pipe by rotating the adjusting rod and adjusting plate, and then fixed by the fixing components to achieve the effect of adjusting the screening diameter, thereby further improving the practicality of the device.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1This embodiment of a pelletizing device for treating landfill fly ash includes a support base 1, a support frame 2 installed at an angle on the right side of the support base 1, a shell 3 fixed on the inner wall of the support frame 2, a motor 4 fixed on the right side of the support frame 2, a rotating rod 5 fixed on the output shaft of the motor 4, a pelletizing disc 6 fixed on the outer peripheral wall of the rotating rod 5, and a discharge mechanism on the shell 3. In use, the motor 4 drives the pelletizing disc 6 to rotate, thereby forming the landfill fly ash into pellets. When the fly ash is pelletized, the shell 3 can play a certain role in shielding, preventing the formed fly ash pellets from flying out of the equipment along the inner wall of the pelletizing disc 6. The shell 3 blocks the fly ash pellets and collects them inside the shell 3, which plays a role in collecting and discharging them. Furthermore, the discharge mechanism screens the fly ash pellets to improve the pelletizing quality.

[0023] The outer shell 3 is a cylindrical hollow shell, and the granulation disc 6 is set inside the outer shell 3. The end of the rotating rod 5 facing away from the motor 4 is rotatably connected to the inner wall of the outer shell 3. A circular hole 8 is opened on the side of the outer shell 3 facing the motor 4. The circular hole 8, the outer shell 3, the granulation disc 6, and the rotating rod 5 are all located on the same central axis. The diameter of the circular hole 8 is smaller than the diameter of the granulation disc 6.

[0024] In use, the fly ash from waste incineration is poured into the granulation disc 6 through the circular hole 8. Then, the motor 4 is started, which drives the rotating rod 5 to rotate. The rotating rod 5 drives the granulation disc 6 to rotate, causing the fly ash to gradually agglomerate into balls. Inside the granulation disc 6, the fly ash balls are subjected to centrifugal force and fly outward along the inner circumferential wall of the granulation disc 6. After hitting the inner wall of the outer shell 3, they fall to the inner bottom wall of the outer shell 3 and accumulate, which facilitates the collection and discharge of the balls. It should be noted that the control method of this application is controlled by a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this application is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.

[0025] Please see Figures 1 to 3The discharge mechanism includes a discharge pipe 701 fixed to the bottom surface of the outer shell 3. An adjusting rod 702 is rotatably connected to the bottom surface of the outer shell 3. An adjusting plate 703 is slidably connected to the outer peripheral wall of the adjusting rod 702. Multiple screening pipes 704 are fixed to the top surface of the adjusting plate 703. Screening hole plates 705 are fixed to the inner peripheral wall of the screening pipes 704. A fixing component is provided on the adjusting plate 703. When manufacturing fly ash balls, a collection frame can be placed at the bottom of the discharge pipe 701. After the fly ash balls fall into the discharge pipe 701, they will further enter the screening pipes 704 and be screened by the screening hole plates 705. The unqualified fly ash balls with smaller diameters will fall into the collection frame through the screening hole plates 705, while the fly ash balls with qualified diameters will remain on the top of the screening hole plates 705. When a certain amount of unqualified fly ash balls are collected, they can be poured back into the granulation disc 6 through the circular hole 8 to re-aggregate into balls until the fly ash is made into fly ash balls of the appropriate diameter.

[0026] The adjusting rod 702 is located on the left side of the discharge pipe 701. The bottom end of the discharge pipe 701 is inserted into the screening pipe 704 and fits with it with a clearance. The screening plates 705 inside the multiple screening pipes 704 are different aperture plates. There are multiple screening pipes 704, and the apertures of the screening plates 705 inside the multiple screening pipes 704 are different. In use, the adjusting rod 702 and the adjusting plate 703 can be rotated to make different screening pipes 704 fit with the discharge pipe 701. Then, they can be fixed by the fixing component to achieve the effect of adjusting the screening diameter, thereby further improving the practicality of the device.

[0027] The adjusting plate 703 is a circular plate, the adjusting rod 702 and the adjusting plate 703 are located on the same central axis, and multiple screening tubes 704 are equidistantly distributed along the circumference of the adjusting rod 702.

[0028] Please see Figures 1 to 3 In this embodiment, the fixing component includes a threaded ring 706 rotatably connected to the outer peripheral wall of the discharge pipe 701. The outer peripheral wall of the screening pipe 704 is provided with a threaded groove 707 adapted to the threaded ring 706. The bottom end of the adjusting rod 702 is fixed with a limiting plate 708. A spring 709 is fitted on the outer peripheral wall of the adjusting rod 702. When it is necessary to screen fly ash balls of different diameters, the threaded ring 706 is rotated to disengage it from the threaded groove 707. At this time, the adjusting plate 703 can be slid down to cooperate with the limiting plate 708 to compress the spring 709, thereby causing the screening pipe 704 to disengage from the discharge pipe 701. Furthermore, the adjusting plate 703 is rotated to rotate the screening plate 705 of other apertures to the bottom of the discharge pipe 701. Then the adjusting plate 703 is released, and the spring 709 lifts it up. Finally, the threaded ring 706 is rotated to make it threadedly connected to the threaded groove 707.

[0029] A conical bucket 710 is fixed to the bottom surface of the screening tube 704, and a spring 709 is set at the bottom of the adjusting plate 703. The discharge tube 701 and the rightmost screening tube 704 are vertically opposite each other.

[0030] The working principle of the above embodiments is as follows:

[0031] (1) When in use, the fly ash after the garbage incineration is poured into the granulation disc 6 through the circular hole 8, and then the motor 4 is started. The motor 4 drives the rotating rod 5 to rotate, and the rotating rod 5 drives the granulation disc 6 to rotate, so that the fly ash gradually agglomerates into balls. The fly ash balls are subjected to centrifugal force inside the granulation disc 6 and fly out along the inner peripheral wall of the granulation disc 6. After hitting the inner wall of the outer shell 3, they fall to the inner bottom wall of the outer shell 3 to collect, which facilitates the collection and discharge of the balls.

[0032] (2) When manufacturing fly ash balls, a collection frame can be placed at the bottom of the discharge pipe 701. After the fly ash balls are manufactured, they will fall into the discharge pipe 701 and then enter the screening pipe 704 and be screened through the screening hole plate 705. The unqualified fly ash balls with smaller diameters will fall into the collection frame through the screening hole plate 705, while the fly ash balls with qualified diameters will remain at the top of the screening hole plate 705. When a certain amount of unqualified fly ash balls are collected, they can be poured back into the granulation disc 6 through the circular hole 8 to re-aggregate into balls until the fly ash is made into fly ash balls of the appropriate diameter.

[0033] (3) When it is necessary to screen fly ash balls of different diameters, rotate the threaded ring 706 to disengage it from the threaded groove 707. At this time, the adjusting plate 703 can be slid down to cooperate with the limiting plate 708 to compress the spring 709, thereby causing the screening tube 704 to disengage from the discharge tube 701. Further, rotate the adjusting plate 703 to rotate the screening plate 705 of other apertures to the bottom of the discharge tube 701. Then, release the adjusting plate 703, and the spring 709 will lift it up. Finally, rotate the threaded ring 706 to make it threadedly connected with the threaded groove 707.
