At the middle position inside the stirring barrel 17, a crushing component is arranged. On the outer surface of the crushing component, there are multiple groups of scraper groups 15 arranged linearly. The scraper groups 15 are in contact with the top of the inner wall of the stirring barrel 17. Inside the stirring barrel 17, a screen 16 is fixedly installed at the position below the crushing component. Inside the stirring barrel 17, a blanking frame 32 is fixedly installed at the position below the screen 16. At the position near the screen 16 on the crushing component, a material cleaning component 19 is arranged. One side of the material cleaning component 19 is in contact with the screen 16. On one side of the outer surface of the stirring barrel 17, a cleaning device 2 is arranged.

[0027] In this embodiment, the bracket 1 is made by welding multiple angle steels and stainless steel plates.

[0028] Designed in this way, the bracket 1 ensures that the stirring barrel 17 can be stably placed.

[0029] The stirring barrel 17 is processed from stainless steel plates, and a barrel cover 18 is detachably installed at the upper end of the stirring barrel 17.

[0030] On the barrel cover 18, feed inlets 24 are symmetrically arranged. Different types of biomass fuels can enter from the feed inlets 24. In this embodiment, two feed inlets 24 are set, which can improve the feeding rate of biomass materials.

[0031] On one side of the outer surface of the stirring barrel 17, an observation window 3 is fixedly installed. The observation window 3 is made of transparent acrylic board.

[0032] On the outer surface of the stirring barrel 17, at the position below the observation window 3, a PLC controller 4 is fixedly installed.

[0033] As Figure 3 shown, the crushing component includes a motor bracket 110 fixedly installed at the position near the upper part of the inner wall of the stirring barrel 17. The motor bracket 110 is made by welding multiple stainless steel pipes.

[0034] At the middle position of the motor bracket 110, a motor 11 is fixedly installed. The power output end of the motor 11 is arranged downward in the stirring barrel 17. The control end of the motor 11 is electrically connected to the PLC controller 4.

[0035] The PLC controller 4 can control the motor 11 to rotate forward and backward.

[0036] The power output end of the motor 11 is fixedly installed with a rotating shaft 12. The other end of the rotating shaft 12 is rotatably installed on the screen 16 through a bearing.

[0037] The outer surface of the rotating shaft 12 is wound with crushing blades 13.

[0038] In this embodiment, the crushing blade 13 is arranged in the same spiral structure as the auger, which can fully crush the biomass material and enable the crushing blade 13 to convey and mix the material.

[0039] A crushing chamber is arranged between the outer surface of the crushing blade 13 and the inner wall of the stirring barrel 17.

[0040] The scraper group 15 is fixedly installed on the outer surface of the crushing blade 13.

[0041] As Figures 4-5 As shown together, the scraper group 15 includes a fixed frame 150 fixedly installed on the outer surface of the crushing blade 13.

[0042] Two T-shaped columns 151 are vertically arranged at the middle position near the bottom surface of the crushing blade 13 inside the fixed frame 150, and the two T-shaped columns 151 are arranged symmetrically at intervals.

[0043] Springs 152 are sleeved on the outer surfaces of the two T-shaped columns 151.

[0044] The outer surfaces of the two T-shaped columns 151 are also sleeved with the same connecting frame 153. One end of the spring 152 abuts against the bottom surface near the crushing blade 13 inside the fixed frame 150, and the other end of the spring 152 abuts against the connecting frame 153.

[0045] The spring 152 is in a compressed state.

[0046] The other end of the connecting frame 153 penetrates through the fixed frame 150 and is fixedly installed with a scraper 154, and the scraper 154 abuts against the inner wall of the stirring barrel 17.

[0047] With such a design, the power output end of the motor 11 drives the rotating shaft 12 to rotate, that is, drives the crushing blade 13 to rotate. At the same time, the scraper group 15 rotates, and under the action of the spring 152, the scraper 154 scrapes the inner wall of the stirring barrel 17 to clean the material powder adhered to the inner wall of the stirring barrel 17.

[0048] As Figure 6 As shown, the material cleaning assembly 19 includes a fixed sleeve 190 fixedly sleeved on the rotating shaft 12 near the screen 16.

[0049] Connecting shafts 191 are vertically arranged on the outer surface of the fixed sleeve 190.

[0050] A cleaning brush 192 is fixedly installed on the surface of the connecting shaft 191 near the screen 16, and the other end of the cleaning brush 192 contacts the screen 16.

[0051] The cleaning component 19 rotates following the rotating shaft 12, enabling the cleaning brush 192 to clean the screen 16, capable of cleaning the materials in the screen holes of the screen 16, avoiding blockage of the screen 16, and improving the filtering effect.

[0052] In this embodiment, the mesh size of the screen 16 matches the debris mixture of the shredded biomass fuel and other energy fuel.

[0053] At the middle position of the lower end of the feeding frame 32, a discharge pipe 31 is fixedly installed, and a valve (not marked in the figure) is arranged on the surface of the discharge pipe 31.

[0054] The valve controls the opening and closing of the discharge pipe 31, which is convenient to operate.

[0055] The cleaning device 2 includes a delivery pipe 23 fixedly installed on the bucket cover 18, and one end of the delivery pipe 23 connected to the bucket cover 18 penetrates into the interior of the mixing bucket 17.

[0056] The other end of the delivery pipe 23 is fixedly installed with a water pump 22, and the other end of the water pump 22 is fixedly installed with a water tank 21 through a water pipe.

[0057] One side of the water tank 21 is fixedly connected with a water inlet pipe 29, a water valve (not marked in the figure) is arranged on the surface of the water inlet pipe 29, and the other end of the water valve is connected to an external main water pipe through a water pipe.

[0058] Water injection into the water tank 21 is controlled by the water valve.

[0059] A circulation pump 28 is fixedly installed at the lower end position of the water tank 21, and the other end of the circulation pump 28 is fixedly connected with an installation pipe 27.

[0060] The other end of the installation pipe 27 is fixedly connected with a filter plate 26, and the other end face of the filter plate 26 is fixedly connected with a circulation pipe 25.

[0061] The circulation pipe 25 is simultaneously connected to a position on one side of the feeding frame 32.

[0062] The PLC controller 4 is connected to an external power supply through a wire, the input end of the water pump 22 is electrically connected to the output end of the PLC controller 4 through a wire, and the input end of the circulation pump 28 is electrically connected to the output end of the PLC controller 4 through a wire.

[0063] With such a design, the shredding component and the cleaning device 2 are controlled by the PLC controller 4, which is simple to operate and simplifies the operation steps of workers.

[0064] During use, the biomass materials to be mixed and crushed are conveyed into the interior of the stirring barrel 17 through the feed inlet 24. The biomass fuel mixing device is started, and the power output end of the motor 11 is controlled by the PLC controller 4 to rotate forward and backward. The power output end of the motor 11 drives the rotating shaft 12 to drive the crushing blades 13 to rotate. The crushing blades 13 start to crush the biomass mixed materials inside the stirring barrel 17. Under the forward and backward rotation of the motor 11, the biomass mixed materials tumble up and down inside the stirring barrel 17 under the action of the crushing blades 13, ensuring thorough crushing of the materials and uniform mixing of the biomass materials. As continuous crushing progresses, when the qualified crushed particles are conveyed to the bottom surface inside the stirring barrel 17, they are filtered into the blanking frame 32 under the action of the screen 16. The materials that cannot be filtered are conveyed back to the upper part for further crushing, enhancing the effect of the crushing blades 13 until all crushing is completed.

[0065] Under the filtering action of the screen 16, finally, the biomass fuel mixture falls into the blanking frame 32. At this time, the valve on the surface of the discharge pipe 31 is opened, and the crushed mixture of the biomass fuel and other energy fuels flows out from the valve to the next processing step.

[0066] During crushing, the scraper 154 scrapes the inner wall of the stirring barrel 17 to prevent adhesion of materials, and the cleaning brush 192 sweeps the screen 16 to prevent blockage of the screen 16.

[0067] After the crushing is completed, first, the water valve on the surface of the water inlet pipe 29 is opened, and water is injected into the water tank 21. The PLC controller 4 is used to control the driving water pump 22 to start, and the water in the water tank 21 is injected into the stirring barrel 17 through the delivery pipe 23. At this time, the motor 11 is in a continuous startup state. The scraper group 15 on the surface of the crushing blades 13 further scrapes and cleans the inner wall along with the injection of water until the inner wall of the stirring barrel 17 is cleaned. At the same time, the cleaning brush 192 cleans the surface of the screen 16, and the waste water flows into the blanking frame 32. Through the circulation pipe 25, at this time, the PLC controller 4 starts the circulation pump 28, and the waste water in the circulation pipe 25 is pumped back into the water tank 21 for recycling. When the circulation pump 28 is in operation, the crushed residues in the waste water are filtered by the filter plate 26 and retained in the blanking frame 32. After the cleaning is completed, the circulation pump 28 is closed, and the valve of the discharge pipe 31 is opened to discharge the final waste water mixture for treatment, saving water resources during the cleaning process.

[0068] The entire process is detected through the observation window 3 to improve the crushing effect.

[0069] For those of ordinary skill in the art, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, the changes, modifications, substitutions, and deformations made to the embodiments still fall within the protection scope of the present invention.
