Abstract
Description
Technical Field
[0001] This invention relates to the field of waste residue recycling technology, and in particular to a fuel waste residue recycling and processing equipment. Background Technology
[0002] Fuel waste residue is a solid residue generated during fuel combustion. It needs to be disposed of through landfill, resource utilization, and other methods. Among these methods, recycling after crushing is one such resource utilization method. Currently, after crushing, fuel waste residue usually undergoes only one direct screening. Residue that does not meet the requirements will remain on the shell or semi-circular screen and be repeatedly crushed, which can easily cause blockage of the arc-shaped screen. Sometimes, manual cleaning is required, making the operation quite troublesome. Summary of the Invention
[0003] To address the problems in the background art, the present invention provides a fuel waste recycling and processing device, which increases the screen aperture size of the semi-circular screen, reduces slag blockage, and ensures smooth screening. At the same time, combined with the secondary screening mechanism of the inclined screen and screen cylinder, slag that meets the particle size requirements can fall smoothly through the bottom side of the square cone bucket, while slag that does not meet the standard is returned to the upper shell through the vertical cylinder for further crushing.
[0004] The present invention provides a fuel waste recycling and processing equipment, specifically comprising: a crushing and screening assembly and a return material conveying assembly; The crushing and screening assembly includes an upper shell, a middle shell, and a lower shell; the upper shell and the middle shell are connected by bolts, and the middle shell and the lower shell are also connected by bolts.

The return material conveying assembly includes an inclined connecting cylinder, a screen cylinder, a locking frame, a vertical cylinder, a retainer, and an upper drive motor. The inclined upper end of the square-structured inclined connecting cylinder is inserted into the discharge port of the lower housing and contacts the inclined lower end of the inclined screen, and is fixedly connected to the lower housing by bolts. The screen cylinder consists of annular frames at both ends and a circular screen in the middle, and is placed between two sets of locking frames. The inclined upper ends of the two sets of locking frames are respectively connected to the inclined lower end of the inclined connecting cylinder by bolts. The vertical cylinder is placed at the outer end of the outer connecting plate, with a lower inclined docking cylinder at the lower end and an upper inclined docking cylinder at the upper end.

[0005] Furthermore, auxiliary racks are bolted to both sides of the lower end of the inner wall of the upper housing. The auxiliary racks on one side are arc-shaped and arranged in the same direction as the crushing shaft.
[0006] Furthermore, a crushing shaft is rotatably installed inside the middle shell, with both ends of the crushing shaft passing through the middle shell and inserted into the bearing seats. Seven sets of fixed discs are fixedly connected to the crushing shaft, and four sets of connecting rods are interspersed between the seven sets of fixed discs. A crushing hammer is rotatably connected to the four sets of connecting rods. A crushing motor is also installed on the outside of the middle shell, and the motor shaft of the crushing motor is inserted into the crushing shaft through a hexagonal insert. A semi-circular screen is also installed on the inside of the middle shell, and an observation door is also installed on the outside.
[0007] Furthermore, the semi-circular screen is placed on the bottom side of the breaker hammer, the side frames are attached to the inner wall of the middle shell, the upper frame is placed in the stepped groove on the inner side of the top of the middle shell, and the screen hole size of the inclined screen is smaller than that of the semi-circular screen and is consistent with the screen hole size of the circular screen on the screen cylinder.
[0008] Furthermore, the baffle is composed of a vertical plate and an inclined horizontal plate, with the vertical plate inclined toward the discharge port and the inclined horizontal plate inclined downward toward the top of the vertical plate.
[0009] Furthermore, the inner bottom of the inclined upper end of the screen cylinder is lower than the inner bottom of the inclined lower end of the inclined connecting cylinder. The two inner ends of the inclined connecting cylinder are respectively provided with baffle blocks. The inclined lower ends of the two sets of baffle blocks are in contact with the annular frame of the inclined upper end of the screen cylinder. A lower drive motor is also fixed on the top side of the inclined connecting cylinder. A drive gear is installed on the motor shaft of the lower drive motor, and the drive gear meshes with the gear ring installed on the annular frame of the screen cylinder.
[0010] Furthermore, the bottom sides of the two sets of positioning frames do not contact each other and form a set of material drop strip holes. The top of the return material positioning frame is respectively attached to the bottom side of the inclined connecting cylinder and the two sets of positioning frames. All the material drop strip holes are placed inside the return material positioning frame. The inside of the return material positioning frame is provided with a set of inclined baffles facing the lower return material hole on the lower housing. The inclined lower end of the inclined baffle is flush with the bottom end of the lower return material hole.
[0011] Furthermore, the bottom end of the spiral conveying roller inside the vertical cylinder is lower than the inclined lower end of the lower inclined docking cylinder. The lower end of the rotating shaft of the spiral conveying roller passes through the vertical cylinder and through the outer connecting plate to be inserted into the bearing seat at the bottom end of the outer connecting plate.

The electric push rod is fixedly connected to the vertical cylinder through the fixed seats at the upper and lower ends.
[0013] The fuel waste recycling and treatment equipment provided by this invention has the following beneficial effects: This invention increases the screen aperture size of the semi-circular screen, reduces slag blockage, and ensures smooth screening. At the same time, the combination of the inclined screen and the screen cylinder secondary screening mechanism allows slag that meets the particle size requirements to fall smoothly through the bottom of the square cone hopper, while slag that does not meet the standard flows back to the upper shell through the vertical cylinder for further crushing.
[0014] Furthermore, the inclined screen not only enables the reprocessing of the slag after the initial screening by the semi-circular screen, but also allows the slag to slide smoothly into the screen cylinder along the inclined connecting cylinder under the guidance of the baffle. Under the coordinated action of the lower drive motor and drive gear, the screen cylinder rotates stably between the two sets of clamping frames, ensuring that the slag that meets the requirements can fall accurately into the return material clamping frame. With the help of the inclined baffle design in the return material clamping frame, it flows smoothly back through the lower return hole and is finally discharged through the bottom side of the square cone hopper.
[0015] In addition, the present invention is equipped with a baffle plate, which effectively blocks the material from the discharge port at the lower end of the inclined screen cylinder, providing the screen cylinder with sufficient time to screen out all the qualified slag and preventing qualified slag from sliding into the vertical cylinder. When a certain amount of slag that is difficult to screen accumulates in the screen cylinder, the electric push rod can automatically pull the baffle plate up, so that the slag can flow smoothly into the vertical cylinder through the lower inclined docking cylinder, realizing the flexible processing and reuse of slag.
[0016] Finally, the spiral conveyor rollers inside the vertical cylinder, driven by the upper drive motor, rotate and push the slag upwards, and then flow back to the upper shell along the upper inclined docking cylinder, forming a slag recycling crushing and screening system, which further improves the comprehensiveness and efficiency of slag processing.

Detailed Implementation
[0021] To make the objectives, solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.
[0022] Example 1: Please refer to Figures 1 to 10 : This invention proposes a fuel waste recycling and processing device, comprising: a crushing and screening assembly 1 and a return material conveying assembly 2; The crushing and screening assembly 1 includes an upper shell 101, a middle shell 102, and a lower shell 103. The upper shell 101 and the middle shell 102 are connected by bolts, and the middle shell 102 and the lower shell 103 are also connected by bolts. The bottom of the lower shell 103 is a square cone structure, and a set of inclined screens 1031 is installed on the inner side of the lower shell 103. A set of baffles 10311 are respectively provided on both sides of the inclined lower end of the inclined screen 1031, facing the discharge port 1032 on the lower shell 103. A set of external connecting plates 1033 is also fixedly connected to the outer side of the lower shell 103, and a return material clip frame 1034 is fixed on the external connecting plate 1033. The return material conveying assembly 2 includes an inclined connecting cylinder 201, a screen cylinder 202, a locking frame 203, a vertical cylinder 204, a retainer 205, and an upper drive motor 206. The inclined upper end of the square-structured inclined connecting cylinder 201 is inserted into the discharge port 1032 of the lower housing 103 and contacts the inclined lower end of the inclined screen 1031, and is fixedly connected to the lower housing 103 by bolts. The screen cylinder 202 consists of annular frames at both ends and a circular screen in the middle, and is placed between two sets of locking frames 203. The inclined upper ends of the two sets of locking frames 203 are respectively connected to the inclined lower ends of the inclined connecting cylinder 201 by bolts. The vertical cylinder 204 is placed at the outer end of the outer connecting plate 1033, and the lower end is provided with a downward inclined pair. The receiving cylinder 2041 has an upper inclined receiving cylinder 2042 at its upper end, and a top cover 2044 is bolted to the top end. The inclined upper end of the lower inclined receiving cylinder 2041 is bolted to two sets of locking frames 203 respectively. The inclined lower end of the upper inclined receiving cylinder 2042 is inserted into the upper return hole 1012 of the upper housing 101, and the arc plates 20421 on both sides of the upper inclined receiving cylinder 2042 are attached to the outer wall of the upper housing 101. A spiral conveying roller 2043 is installed inside the vertical cylinder 204. One end of the retainer 205 is bolted to the vertical cylinder 204, and the other end is bolted to the middle housing 102. The upper drive motor 206 is mounted on the top cover 2044 through a bracket.
[0023] In embodiments of the present invention, such as Figures 5 to 6 As shown, a crushing shaft 1021 is rotatably mounted inside the middle housing 102. Both ends of the crushing shaft 1021 extend out of the middle housing 102 and are inserted into bearing seats. Seven sets of fixed discs 1022 are fixedly connected to the crushing shaft 1021, and four sets of connecting rods 1023 are interspersed between the seven sets of fixed discs 1022. A crushing hammer 1024 is rotatably connected to the four sets of connecting rods 1023. A crushing motor 1025 is also mounted on the outside of the middle housing 102, and the motor shaft of the crushing motor 1025... A hexagonal insert is inserted into the crushing shaft 1021. A semi-circular screen 1026 is installed on the inner side of the middle shell 102, and an observation door 1027 is installed on the outer side. The crushing motor 1025 drives the crushing shaft 1021, the fixed plate 1022, and the connecting rod 1023 to rotate, while driving the crushing hammer 1024 to crush the waste residue. The waste residue is then screened once through the semi-circular screen 1026. During the crushing and screening process, the waste residue can be observed through the observation door 1027.
[0024] In embodiments of the present invention, such as Figure 6 As shown, auxiliary racks 1011 are bolted to both sides of the lower end of the inner wall of the upper shell 101. The auxiliary rack 1011 on one side has an arc-shaped structure and is arranged in the same direction as the crushing shaft 1021. During the crushing process, the slag thrown up by the crushing hammer 1024 will hit the auxiliary rack 1011, which can play an auxiliary crushing role.
[0025] In embodiments of the present invention, such as Figures 5 to 9 As shown, the semi-circular screen 1026 is placed on the bottom side of the breaker hammer 1024, with the side frames attached to the inner wall of the middle shell 102. The upper frame is placed in the stepped groove on the inner side of the top of the middle shell 102. The screen hole size of the inclined screen 1031 is smaller than that of the semi-circular screen 1026 and is consistent with the screen hole size of the circular screen on the screen cylinder 202. By increasing the screen hole size of the semi-circular screen 1026, the slag is prevented from blocking the semi-circular screen 1026. The inclined screen 1031 performs secondary screening, allowing the slag that meets the requirements to fall down along the inclined screen 1031. Since the inclined screen 1031 is an inclined structure, the slag that meets the requirements is slid into the screen cylinder 202 through the discharge port 1032 and the inclined connecting cylinder 201 for further screening. All the slag that meets the requirements can be screened out in the screen cylinder 202.
[0026] In embodiments of the present invention, such as Figure 7 As shown, the baffle 10311 is composed of a vertical plate and an inclined horizontal plate. The vertical plate is inclined towards the discharge port 1032, and the inclined horizontal plate is inclined downward towards the top of the vertical plate. This allows the slag falling from the semi-circular screen 1026 to fall onto the screen in the middle of the inclined screen 1031, preventing it from falling onto the lower edge of the inclined screen 1031.
[0027] In embodiments of the present invention, such as Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, the inner bottom of the inclined upper end of the screen cylinder 202 is lower than the inner bottom of the inclined lower end of the inclined connecting cylinder 201. Two baffle blocks 2011 are respectively provided at both ends of the inner side of the inclined connecting cylinder 201. The inclined lower ends of the two sets of baffle blocks 2011 are in contact with the annular frame of the inclined upper end of the screen cylinder 202. A lower drive motor 2012 is also fixed to the top side of the inclined connecting cylinder 201. A drive gear is installed on the motor shaft of the lower drive motor 2012, and the drive gear meshes with the gear ring 2021 installed on the annular frame of the screen cylinder 202. The bottom sides of the two sets of locking frames 203 do not contact each other and form a set of material drop strip holes. The top of the return material locking frame 1034 is respectively attached to the inclined connecting cylinder 201 and the two sets of locking frames 203. On the bottom side, all the material drop holes are placed inside the return material card frame 1034. Inside the return material card frame 1034, there is a set of inclined baffles facing the lower return material hole 1035 on the lower housing 103. The inclined lower end of the inclined baffle is level with the bottom end of the lower return material hole 1035, which allows all the slag material sliding out of the inclined connecting cylinder 201 to slide into the screen cylinder 202. Under the drive of the lower drive motor 2012 and the drive gear, the screen cylinder 202 rotates stably between the two sets of card frames 203, ensuring that the slag material that meets the requirements can fall accurately into the return material card frame 1034. With the help of the inclined baffle design inside the return material card frame 1034, it flows smoothly back through the lower return material hole 1035 and is finally discharged through the bottom side of the square cone hopper.
[0028] In embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the bottom end of the spiral conveying roller 2043 inside the vertical cylinder 204 is lower than the inclined lower end of the lower inclined docking cylinder 2041. The lower end of the rotating shaft of the spiral conveying roller 2043 passes through the vertical cylinder 204 and passes through the outer connecting plate 1033 and is inserted into the bearing seat at the bottom end of the outer connecting plate 1033. The upper end of the rotating shaft of the spiral conveying roller 2043 passes through the top cover 2044 and the bearing seat on the top cover 2044, and is inserted and connected to the hexagonal insert at the bottom end of the motor shaft of the upper drive motor 206. The spiral conveying roller 2043 can be driven by the upper drive motor 206, so that the slag material that has slid into the vertical cylinder 204 can move upward under the drive of the spiral conveying roller 2043.
[0029] In embodiments of the present invention, such as Figure 8 and Figure 9 As shown, the lower inclined docking cylinder 2041 has a set of inclined slopes on the inner bottom side of its inclined upper end, and one end of the inclined slopes is in contact with the inclined bottom end of the inner side of the screen cylinder 202. The upper end of the lower inclined docking cylinder 2041 that connects with the two sets of locking frames 203 has a notch, and a baffle plate 2045 is inserted into the notch. The baffle plate 2045 is in contact with the annular frame at the lower inclined end of the screen cylinder 202, and the top of the baffle plate 2045 is fixedly connected to the telescopic end of the electric push rod 2046. The electric push rod 2046 is fixedly connected to the vertical cylinder 204 through the fixed seats at the upper and lower ends. When a certain amount of slag that is difficult to screen accumulates in the screen cylinder 2024, the baffle plate 2045 is lifted upward by the electric push rod 2046, so that the slag that is difficult to screen in the screen cylinder 202 can slide into the lower inclined docking cylinder 2041 along the inclined slope.
[0030] The specific usage and function of this embodiment: In this invention, fuel waste is fed into the upper shell 101. The crushing motor 1025 drives the crushing shaft 1021, the fixed disk 1022, and the connecting rod 1023 to rotate, while simultaneously driving the crushing hammer 1024 to crush the waste. The waste is then screened once through a semi-circular screen 1026, and then screened again using an inclined screen 1031. The waste that meets the requirements falls through the bottom of the square cone hopper, while the waste that does not meet the requirements slides into the screen cylinder 202 along the inclined connecting cylinder 201 under the obstruction of the baffle 10311. Driven by the lower drive motor 2012 and the drive gear, the screen cylinder 202 rotates between two sets of locking frames 203, allowing the waste that meets the requirements to fall into the screen. The material flows into the return material frame 1034 and back through the lower return material hole 1035 along the inclined baffle in the return material frame 1034. It falls through the bottom side of the square cone hopper and is blocked by the baffle plate 2045 at the inclined lower end of the screen cylinder 202, so that the screen cylinder 202 can screen out all the slag that meets the requirements and prevent the slag that meets the requirements from entering the vertical cylinder 204. When a certain amount of slag that is difficult to screen accumulates in the screen cylinder 2024, the baffle plate 2045 is lifted upward by the electric push rod 2046, so that the slag flows into the vertical cylinder 204 through the lower inclined docking cylinder 2041. The upper drive motor 206 drives the spiral conveyor roller 2043 to rotate, pushing the slag upward and back into the upper shell 101 through the upper inclined docking cylinder 2042 for further crushing.
