Description

Technical Field

[0001] The present invention relates to the technical field of garbage pretreatment, and in particular to garbage pretreatment equipment and a treatment method thereof. Background Art

[0002] In the field of waste disposal, the treatment of landfill leachate is a critical step. Landfill leachate contains a large amount of impurities. If not properly treated, it will not only cause serious environmental pollution but also affect the normal operation of subsequent treatment processes and equipment.

[0003] Currently, common landfill leachate impurity filtration and treatment equipment suffers from numerous shortcomings. Due to the diverse nature of impurities in landfill leachate, traditional screen-based decontamination equipment can easily leave stubborn impurities trapped or entangled on the tines during the filtration and removal process. These residual impurities accumulate with continued operation, reducing filtration efficiency and potentially affecting the equipment's stable operation and service life. Furthermore, existing cleaning methods are often relatively simple and difficult to completely remove residual impurities from the tines, failing to meet the demand for efficient and stable filtration in real-world production. Summary of the Invention

[0004] The object of the present invention is to provide a garbage pre-processing device and a processing method thereof to overcome the above-mentioned defects in the prior art.

[0005] A garbage pre-processing device includes a frame, a right-angle motor, a grille plate and a cleaning mechanism. Support plates are symmetrically provided on both sides of the frame. The upper and lower sides of the frame are respectively rotatably connected to rotating shafts. The right-angle motor is installed on the outside of the frame and its output shaft is connected to one of the rotating shafts. Sprockets are respectively installed at both ends of each rotating shaft. Chains are provided on the two sprockets on the same side. A grille plate is provided between the two chains. A number of rake teeth with bent ends are evenly distributed on the grille plate. The cleaning mechanism is provided on the rear side of the frame and is used to clean impurities remaining on the rake teeth.

[0006] Preferably, a guide hopper for discharging impurities is provided on the rear side of the frame.

[0007] Preferably, the cleaning mechanism includes a movable plate, a cleaning component, a turntable, a driving plate 1 and a driving plate 2, the two ends of the movable plate are respectively slidably connected to the slide rails at the two ends of the guide hopper, the movable plate is evenly distributed with cleaning components corresponding to the same row of rake teeth, the turntable is installed at one end of one of the rotating shafts, one end of the driving plate 1 is hinged to the turntable through a pin shaft, one end of the driving plate 2 is hinged to the other end of the driving plate 1 through a pin shaft, and the other end of the driving plate 2 is hinged to one end of the movable plate through a pin shaft.

[0008] Preferably, the cleaning component includes a fixing plate, a cutting knife, a dial plate, a cleaning brush and a driving shaft. The fixing plate is arranged on the side of the moving plate. A cutting knife is arranged on the top of the fixing plate. Two dial plates are arranged in each fixing plate. The dial plate is rotatably connected to both ends of the fixing plate through a connecting shaft. A torsion spring is sleeved on one end of each connecting shaft. One end of the torsion spring is connected to the connecting shaft, and the other end of the torsion spring is connected to the fixing plate. The cleaning brush is rotatably connected to the installation groove on the lower side of the fixing plate, and a first bevel gear is arranged at one end thereof. The driving shaft is rotatably connected to the fixed block on the inner side of the fixing plate. A second bevel gear and a third bevel gear are respectively installed at the upper and lower ends of the driving shaft. The second bevel gear meshes with the fourth bevel gear on the dial plate, and the third bevel gear meshes with the first bevel gear.

[0009] Preferably, the fixing plate is of a "U" - shaped structure.

[0010] Preferably, two cutting knives are provided and symmetrically arranged on the top of the fixing plate.

[0011] Preferably, a housing is arranged outside the installation groove of the fixing plate.

[0012] Preferably, the dial plate is arranged in the fixing plate in an "eight" - shaped structure.

[0013] The treatment method of the above - mentioned garbage pretreatment equipment includes the following steps: S1. Start the right - angle motor. The right - angle motor drives the rotating shaft to rotate. The turntable on the rotating shaft drives the moving plate to slide. The sprocket wheel drives the grille plate to rotate through the chain. The rake teeth on the grille plate filter and lift the impurities in the garbage leachate; S2. When the impurities are lifted to the highest point of the grille plate by the rake teeth, at this time, the moving plate gradually moves from the farthest position from the grille plate towards the grille plate. At the same time, under the action of gravity, the impurities are led out to the collection box through the guide hopper; S3. When the rake teeth contact the cleaning component, the bend at the end of the rake teeth squeezes the two dial plates inwards. The torsion spring on the connecting shaft is twisted. At the same time, the moving plate drives the fixing plate to continue moving, and the moving cutting knife cuts the impurities remaining on the rake teeth; S4. The rake teeth continue to move in the fixing plate. When the rake teeth disengage from the two dial plates, under the action of the torsion spring, the dial plates are driven to rotate reversely and reset, and the cut impurities are flipped upwards and scattered; S5. During the reset process of the dial plate, the cleaning brush is driven to rotate through bevel gear transmission, and the cleaning brush cleans the passing rake teeth.

[0014] The beneficial effects achieved by the present invention are as follows: <> 1. When the grille plate rotates, the rake teeth thereon can effectively filter and lift the impurities in the garbage leachate, realizing the efficient separation of the impurities in the leachate, improving the filtration efficiency, and providing favorable conditions for the subsequent garbage treatment process.

[0015] 2. When the rake teeth come into contact with the cleaning assembly, the ends of the teeth bend and squeeze the paddle, twisting the torsion spring. The cutter moves and cuts off the impurities remaining on the teeth. After the teeth disengage from the paddle, the torsion spring drives the paddle back to its original position, dispersing the cut impurities. Simultaneously, during the paddle reset process, the bevel gear drive drives the cleaning brush to rotate, thoroughly cleaning the teeth. This series of automatic cleaning processes effectively removes residual impurities on the teeth, preventing impurity accumulation from affecting normal operation of the equipment and ensuring long-term stable and efficient operation.

[0016] 3. When the bristles on the cleaning brush pass through the top wall of the installation groove, the bristles on the cleaning brush are moved under the action of the top wall of the installation groove, so that the impurities remaining on the bristles are removed, thereby keeping the cleaning brush clean.

A plurality of rake teeth 41 with bent ends are evenly distributed on the grille plate 4, and the impurities existing in the garbage leachate are filtered and lifted by the rake teeth 41. It should be noted that the cleaning mechanism 5 is arranged at the rear side of the frame 1 and is used for cleaning the impurities remaining on the rake teeth 41. The cleaning mechanism 5 includes a moving plate 51, a cleaning component 52, a turntable 53, a driving plate one 54 and a driving plate two 55. The two ends of the moving plate 51 are respectively slidably connected to the slide rails at both ends of the material guiding hopper 12. In addition, cleaning components 52 corresponding to the same row of rake teeth 41 are evenly distributed on the moving plate 51. The cleaning component 52 includes a fixing plate 521, a cutter 522, a dialing plate 523, a cleaning brush 525 and a driving shaft 526. The fixing plate 521 is of a "U" - shaped structure and is arranged on the side of the moving plate 51. Two cutters 522 are symmetrically arranged at the top of the fixing plate 521. Two dialing plates 523 arranged in an "eight" - shaped structure are provided in each fixing plate 521. The dialing plates 523 are rotationally connected to both ends of the fixing plate 521 through connecting shafts 524. A torsion spring 5241 is sleeved at one end of each connecting shaft 524. One end of the torsion spring 5241 is connected to the connecting shaft 524, and the other end of the torsion spring 5241 is connected to the fixing plate 521. The dialing plates 523 are reset under the action of the torsion of the torsion spring 5241 to throw the cut impurities outwards. In addition, the cleaning brush 525 is rotationally connected to the installation groove 5211 on the lower side of the fixing plate 521, and a bevel gear one 5251 is provided at one end thereof. A housing 528 is provided outside the installation groove 5211 of the fixing plate 521, and part of the cleaning brush 525 can be covered by the housing 528. However, the driving shaft 526 is rotationally connected to the fixing block 5263 on the inner side of the fixing plate 521. Bevel gears two 5261 and bevel gears three 5262 are respectively installed at the upper and lower ends of the driving shaft 526. The bevel gear two 5261 meshes with the bevel gear four 527 on the dialing plate 523, and the bevel gear three 5262 meshes with the bevel gear one 5251. Meanwhile, the turntable 53 is installed at one end of one of the rotating shafts 2. One end of the driving plate one 54 is hinged to the turntable 53 through a pin shaft.

The other end of the driving plate two 55 is hinged to one end of the moving plate 51 through a pin shaft.

[0031] Specific implementation method and principle: When filtering the leachate in the garbage, the right-angle motor 3 is started, and the right-angle motor 3 drives the rotating shaft 2 to rotate. The turntable 53 on the rotating shaft 2 drives the movable plate 51 to slide along the slide rail on the guide hopper 12 through the driving plate 1 54 and the driving plate 2 55. The sprocket on the rotating shaft 2 drives the grid plate 4 to rotate through the chain, and the rake teeth 41 on the grid plate 4 filter and lift the impurities in the leachate. When the impurities are lifted to the highest point of the grid plate 4 by the rake teeth 41, the movable plate 51 gradually moves from the farthest point from the grid plate 4 to the grid plate 4. At the same time, under the action of gravity, the impurities are discharged into the collection box through the guide hopper 12. When the rake teeth 41 come into contact with the cleaning component 52, the bending of the end of the rake teeth 41 squeezes the two dial plates 523 inward, and the torsion spring 5241 on the connecting shaft 524 is twisted. At the same time, the movable plate 51 drives the fixed plate 52 When the pick plate 523 is disengaged from the two pick plates 523, the pick plate 523 is driven to rotate in the opposite direction and reset under the action of the torsion spring 5241, and the cut impurities are pushed upward and dispersed. During the reset of the pick plate 523, the bevel gear 2 5261 is driven to rotate through the bevel gear 4 527, and the bevel gear 3 5262 on the drive shaft 526 drives the bevel gear 1 5251 and the cleaning brush 525 to rotate. The rotating cleaning brush 525 brushes and cleans the rake teeth 41 passing by, making the rake teeth 41 cleaner. When the bristles on the cleaning brush 525 pass through the top wall of the installation groove 5211, the bristles on the cleaning brush 525 are pushed under the action of the top wall of the installation groove 5211, so that the impurities remaining on the bristles are pulled off.

[0032] The above-described embodiments of the present invention do not limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the claims of the present invention.
