Description

Technical Field

[0001] This invention relates to the field of crushing equipment technology, and more specifically, to a sludge biomass energy fuel processing crushing equipment. Background Technology

[0002] Traditional fossil fuel reserves are limited and non-renewable. Developing and utilizing renewable energy is an important way to ensure energy supply security. At the same time, with the increasing awareness of environmental protection and the growing demand for renewable energy, converting sludge into biomass energy fuel has become a highly promising method of sludge treatment and energy development. It can increase energy supply channels and alleviate the energy shortage.

[0003] In the current processing of sludge biomass energy fuel, the crushing of straw, corn cobs, sawdust, peanut shells, etc. is an essential step. However, disc crushers still have shortcomings in use. Due to the large size of the fibrous fragments formed after the initial crushing of straw, corn cobs, sawdust, peanut shells, etc., and the high moisture content of some of them, the fragments stick together, making it easy for the screen at the bottom of the crusher to become clogged. This makes it difficult to discharge the crushed material and is not conducive to improving work efficiency.

[0004] To address the aforementioned issues, a sludge biomass energy fuel processing and crushing device is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, a sludge biomass energy fuel processing and crushing device is provided. This technical solution solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, the present invention can be implemented using the following technical solutions: This invention provides a sludge biomass energy fuel processing and crushing device, including a base, a hopper rotatably connected to the top of the base, a feeding rod fixedly connected inside the hopper, a vertically downward crushing tube on the base, a first crushing component located at the lower part of the crushing tube, a second crushing component located at the upper part of the crushing tube, a semi-circular screen fixedly connected to the bottom of the crushing tube, an arc-shaped unblocking plate fitted inside the screen, and sliding grooves at both ends of the unblocking plate; sliding strips fixedly connected to both sides of the bottom port of the crushing tube. The outer surface of the strip slides into the groove of the unblocking plate. Guide rods are fixedly connected to both ends of the unblocking plate along the axial direction of the screen. One end of the guide rod passes through the crushing tube and extends to the outside. The two guide rods are fixedly connected to a connecting rod at the ends extending to the outside of the crushing tube. Electric cylinders are fixedly connected to both sides of the bottom of the crushing tube. The telescopic ends of the two electric cylinders are fixedly connected to the two ends of the connecting rod respectively. The bottom port of the crushing tube is fixedly connected to the bottom of the screen with a discharge pipe. Side chutes are fixedly connected to both ends of the discharge pipe in the axial direction of the screen.

[0007] Furthermore, the first crushing assembly includes a main shaft, which is rotatably connected to the center of the bottom port of the crushing tube. Multiple crushing blades are uniformly fixedly connected around the outer circumference of the main shaft. The first crushing assembly also includes two fixed blades, which are respectively installed on the inner walls of the two sides of the crushing tube. Each fixed blade has multiple grooves on its inner side. When the main shaft rotates, it will drive the crushing blades to pass through the corresponding grooves.

[0008] Furthermore, the first crushing component also includes a motor, which is fixedly connected to the bottom of the base, and its drive end is fixedly connected to one end of the main shaft.

[0009] Furthermore, the second crushing assembly includes a second main shaft, which is rotatably connected to the center of the top port of the crushing tube. Multiple crushing blades are uniformly fixedly connected around the outer circumference of the second main shaft. The second crushing assembly also includes two fixed blades, which are respectively installed on the inner walls of the two sides of the crushing tube. Each fixed blade has multiple channels on its inner side. When the second main shaft rotates, it will drive the crushing blades to pass through the corresponding channels.

[0010] Furthermore, the first crushing component also includes a first sprocket, which is fixedly connected to the end of the first main shaft away from the motor. The second crushing component also includes a second sprocket, which is located above the first sprocket and is fixedly connected to one end of the second main shaft. The first sprocket and the second sprocket are connected by a chain.

[0011] Furthermore, a reduction gearbox is fixedly connected to one side of the base, the input end of the reduction gearbox is fixedly connected to one end of the main shaft, the output end of the reduction gearbox is fixedly connected to a drive gear, and a gear ring is fixedly connected to the outer circumference of the hopper, the gear ring meshing with the drive gear.

[0012] Furthermore, a conveyor belt is provided below the discharge pipe.

[0013] As described above, the features and advantages of the sludge biomass energy fuel processing and pulverizing device of the present invention are as follows: After secondary crushing, straw, corn cobs, sawdust, peanut shells, etc., are screened through a sieve. Unqualified materials are retained. When the sieve's screening efficiency drops significantly, an electric cylinder extends and retracts, which in turn moves a connecting rod. This connecting rod then moves a guide rod, ultimately causing a dredging plate to move along the axial direction of the sieve with the help of sliding strips and chutes. This pushes the accumulated straw, corn cobs, sawdust, peanut shells, and other fragments out from both ends of the sieve and out through a side chute for further crushing. This avoids the problem in existing technologies where the large fibrous fragments formed after the initial crushing of straw, corn cobs, sawdust, peanut shells, etc., stick together and easily clog the sieve at the bottom of the crusher.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0017] See Figures 1-2 As shown in the figure, an embodiment of the present invention is provided, and a sludge biomass energy fuel processing and crushing device will be described in detail below: In this embodiment, see Figure 1-2 A sludge biomass energy fuel processing and crushing device includes a base 1, a hopper 2 rotatably connected to the top of the base 1, a feeding rod 3 fixedly connected inside the hopper 2, and a vertically downward crushing pipe 4 on the base 1. (See reference...) Figures 8-9 A first pulverizing component is located at the lower part of the interior of the pulverizing tube 4, and a second pulverizing component is located at the upper part of the interior of the pulverizing tube 4. (See reference...) Figures 5-7 A semi-circular screen 5 is fixedly connected to the bottom of the crushing tube 4. An arc-shaped unblocking plate 6 is fitted inside the screen 5. Sliding grooves are opened at both ends of the unblocking plate 6. Sliding strips 10 are fixedly connected to both sides of the bottom port of the crushing tube 4. The outer side of each sliding strip 10 is slidably fitted inside the sliding groove of the unblocking plate 6. Guide rods 7 are fixedly connected to both ends of the unblocking plate 6 along the axial direction of the screen 5. One end of the guide rod 7 passes through the crushing tube 4 and extends to the outside. The two guide rods 7 are fixedly connected to the connecting rod 8 at the ends of the two guide rods 7 extending to the outside of the crushing tube 4. Electric cylinders 9 are fixedly connected to both sides of the bottom of the crushing tube 4. The telescopic ends of the two electric cylinders 9 are fixedly connected to the two ends of the connecting rod 8 respectively. A discharge pipe 11 is fixedly connected to the bottom port of the crushing tube 4 at the bottom of the screen 5. Side chutes 12 are fixedly connected to both ends of the discharge pipe 11 in the axial direction of the screen 5.

[0018] In this embodiment, straw, corn cobs, sawdust, peanut shells, etc., which have been pulverized twice by the second pulverizing component and the first pulverizing component, fall onto the screen 5 in the pulverizing tube 4. Those that meet the size requirements will fall through the mesh and be output, while those that do not meet the size requirements will be retained. When the screening efficiency of the screen 5 decreases significantly, the electric cylinder 9 extends and retracts, thereby driving the connecting rod 8 to move. The connecting rod 8 drives the guide rod 7, which in turn causes the unblocking plate 6 to move along the axial direction of the screen 5 with the cooperation of the sliding strip 10 and the sliding groove. This pushes the accumulated straw, corn cobs, sawdust, peanut shells, and other fragments out from both ends of the screen 5 and discharges them through the side chute 12 for re-pulverization.

[0019] Further reading Figures 8-9 The first crushing component includes a main shaft 13, which is rotatably connected to the center of the bottom port of the crushing tube 4. Multiple crushing blades 14 are evenly fixedly connected around the outer circumference of the main shaft 13. The first crushing component also includes two fixed blades 15, which are respectively installed on the inner walls of the two sides of the crushing tube 4. Multiple grooves are opened on the inner side of each fixed blade 15. When the main shaft 13 rotates, it will drive the crushing blades 14 to pass through the corresponding grooves.

[0020] See Figures 2-3 The first crushing component also includes a motor 16, which is fixedly connected to the bottom of the base 1, and its drive end is fixedly connected to one end of the main shaft 13.

[0021] See again Figures 8-9 The second crushing component includes a second main shaft 18, which is rotatably connected to the center of the top port of the crushing tube 4. Multiple crushing blades 19 are evenly fixedly connected around the outer circumference of the second main shaft 18. The second crushing component also includes two fixed blades 20, which are respectively installed on the inner walls of the two sides of the crushing tube 4. Multiple channels 2 are opened on the inner side of each fixed blade 20. When the second main shaft 18 rotates, it will drive the crushing blades 19 to pass through the corresponding channels 2.

[0022] See Figure 8 The first crushing component also includes a sprocket 17, which is fixedly connected to the end of the main shaft 13 away from the motor 16. The second crushing component also includes a sprocket 21, which is located above the sprocket 17 and is fixedly connected to one end of the main shaft 18. The sprocket 17 and the sprocket 21 are connected by a chain to realize the transmission of power.

[0023] See Figure 2A reduction gearbox 22 is fixedly connected to one side of the base 1. The input end of the reduction gearbox 22 is fixedly connected to one end of the main shaft 18. A horizontally oriented drive gear 23 is fixedly connected to the output end of the reduction gearbox 22. A gear ring 24 is fixedly connected to the outer circumference of the hopper 2. The gear ring 24 meshes with the drive gear 23. The reduction gearbox 22 drives the drive gear 23 to rotate, and then the hopper 2 is driven to rotate through the cooperation between the gear ring 24 and the gear ring 24. After straw, corn cobs, sawdust, peanut shells, etc. are poured into the hopper 2, the straw can be continuously rotated and moved in the hopper 2 by the action of the moving feed rod 3, so as to achieve the effect of continuous feeding.

[0024] Furthermore, a conveyor belt 25 is provided below the discharge pipe 11 for conveying qualified straw, corn cobs, sawdust, peanut shells and other fragments.

[0025] Based on the above embodiments, the following is the complete working process and working principle of the above embodiments: The working state is as follows: Motor 16 drives the main shaft 13 to rotate, then sprocket 17 drives sprocket 21 to rotate via chain drive, sprocket 21 drives the main shaft 18 to rotate, which in turn drives the drive gear 23 to rotate via reduction gearbox 22, and then drives the hopper 2 to rotate through the engagement between the gearbox and the gear ring 24, thus pouring straw, corn cobs, sawdust, peanut shells, etc. into the hopper 2. Then, under the action of the moving feed lever 3, the straw, corn cobs, sawdust, peanut shells, etc. are continuously rotated and agitated in the hopper 2. When the straw, corn cobs, sawdust, peanut shells, etc. are mixed together, the mixture is gradually circulated and agitated. When straw, corn cobs, sawdust, peanut shells, etc., are pushed onto the second crushing component, the rotating main shaft 218 drives the crushing blade 219 to rotate rapidly. This hooks the straw, corn cobs, sawdust, peanut shells, etc., from the bottom of the pile to the fixed blade 20. As the crushing blade 219 continues to rotate and passes through the channel 2, it cuts and crushes the straw, corn cobs, sawdust, peanut shells, etc., into smaller fibrous structures through its interaction with the channel wall. The crushed straw, corn cobs, sawdust, and peanut shells are then... As the material falls within the crushing tube 4, upon contacting the second crushing component, the rotating main shaft 13 drives the crushing blade 14 to rotate rapidly. This hooks and fixes the initially crushed straw, corn cob, sawdust, peanut shells, and other fibers at the blade 15. As the crushing blade 14 continues to rotate and passes through the channel 1, it further cuts and crushes the straw, corn cob, sawdust, peanut shells, etc., into smaller fibrous structures through its interaction with the channel wall. The crushed straw, corn cob, sawdust, peanut shells, etc., are then further crushed within the crushing tube. The material falls into the screen 5. Those that meet the size requirements fall through the mesh and are output via conveyor belt 25, while those that do not meet the size requirements are retained. When the screening efficiency of screen 5 decreases significantly, the electric cylinder 9 extends and retracts, which in turn drives the connecting rod 8 to move. The connecting rod 8 drives the guide rod 7, which in turn causes the unblocking plate 6 to move along the axial direction of screen 5 with the cooperation of the sliding strip 10 and the chute. This pushes the accumulated straw, corn cob, sawdust, peanut shells and other debris out from both ends of screen 5 and discharges through the side chute 12 for re-crushing.
