[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:
[0021] A biomass briquette drying and molding machine with pulverizing function includes a drying chamber 1. A pulverizer 2 is fixedly connected to the top of the drying chamber 1. The discharge port at the bottom of the pulverizer 2 is connected to the inlet 14 at the top of the drying chamber 1. A biomass fuel drying cylinder 7 is fixedly connected to the drying chamber 1 below the inlet 14. The two ends of the biomass fuel drying cylinder 7 are fixedly connected to the two sides inside the drying chamber 1, respectively. Baffles 71 are fixedly installed on the upper part of the biomass fuel drying cylinder 7. The upper ends of the two baffles 71 are fixed to the drying chamber 1 on the front and rear sides of the inlet 14, respectively. A rotating shaft 8 is rotatably connected to the inside of the drying chamber 1 through bearings. The rotating shaft 8 is connected to the biomass fuel drying cylinder 1. The shafts of the fuel drying cylinder 7 are aligned, and a turning blade 81 is fixedly installed on the circumferential wall of the rotating shaft 8. The rotating shaft 8, along with the turning blade 81, is driven by the drive motor 4 to rotate. The turning blade 81 agitates the pulverized biomass fuel inside the biomass fuel drying cylinder 7, allowing the biomass fuel to come into more complete contact with hot air, thereby improving the drying and shaping efficiency of the biomass fuel. One end of the rotating shaft 8 is coaxially connected to the output end of the motor 4, which is fixedly installed on the outer wall of the drying chamber 1. A control switch 3 is fixedly installed on the outer wall of the drying chamber 1 above the motor 4. The control switch 3 is electrically connected to an external power supply via a wire. An electric heating grid 10 is fixedly installed on the lower part of the inner side of the drying chamber 1. An air inlet 15 is opened on the drying chamber 1 below the electric heating grid 10. A fan 5 is fixedly installed at the bottom of the drying chamber 1 below the air inlet 15. The crusher 2, motor 4, fan 5 and electric heating grid 10 are electrically connected to the control switch 3 through wires. Support legs 13 are fixedly installed at the four corners of the bottom of the drying chamber 1. In use, the crusher 2, motor 4 and fan 5 are turned on by the control switch 3, and the electric heating grid 10 is energized and heated. The biomass briquettes to be dried are put into the crusher 2. The biomass entering the crusher 2 can be crushed by the crushing roller and then discharged from the feed inlet 14. The biomass fuel falls into the drying cylinder 7. The fan 5 can send outside air into the drying chamber 1 through the air inlet 15. The air entering the drying chamber 1 can be heated by the electric heating grid 10 and then move upward. When the upward hot air passes through the inside of the biomass fuel drying cylinder 7, it can heat and dry the pulverized biomass fuel in the biomass fuel drying cylinder 7. During this process, the motor 4 drives the rotating shaft 8 to rotate together with the turning blades 81. The turning blades 81 can turn the biomass fuel inside the biomass fuel drying cylinder 7, so that the biomass fuel can better contact the hot air and accelerate the drying and shaping of the biomass fuel.
[0022] An arc-shaped sealing mesh plate 72 is rotatably connected to the discharge window at the lower part of the biomass fuel drying cylinder 7 via a hinge shaft. The hinge shaft at the lower part of the biomass fuel drying cylinder 7 is located on the side near the electric push rod 6. An electric push rod 6 is fixedly installed on the rear side wall of the drying chamber 1. The telescopic end of the electric push rod 6 extends into the interior of the drying chamber 1 and is fixedly installed with a push block 61. The push block 61 abuts against the outer wall of the arc-shaped sealing mesh plate 72. A guide hopper 9 is inclinedly fixedly connected in the drying chamber 1 below the arc-shaped sealing mesh plate 72. The two sides of the guide hopper 9 are fixedly connected to the two sides inside the drying chamber 1, respectively. A ventilation channel is provided between the upper end of the guide hopper 9 and the inner side wall of the drying chamber 1. The lower end of the guide hopper 9 is connected to the discharge nozzle 11 fixed on the front side wall of the drying chamber 1. A sealing cover 12 is fitted on the outer end of the discharge nozzle 11. By opening the sealing cover 12 and driving the electric push rod 6 to move the push block 61 backward, the arc-shaped sealing mesh plate 72 can be moved. 2. Under its own gravity, the biomass fuel in the drying cylinder 7 flips downward and opens around the hinge axis. At this time, the dried biomass fuel in the drying cylinder 7 can fall from the discharge window at the bottom of the drying cylinder 7 onto the guide hopper 9 and slide down along the guide hopper 9 to the discharge nozzle 11 for automatic discharge. This facilitates the collection of dried biomass fuel. After the biomass fuel is dried, the sealing cover 12 can be opened manually, and the electric push rod 6 can be driven by the control switch 3 to move the push block 61 backward. At this time, the arc-shaped sealing mesh plate 72 loses the support of the push block 61 and can flip downward and open around the hinge axis under its own gravity. At this time, the dried biomass fuel in the drying cylinder 7 can fall from the discharge window at the bottom of the drying cylinder 7 onto the guide hopper 9 and slide down along the guide hopper 9 to the discharge nozzle 11 for automatic discharge. This allows the collection of dried biomass fuel.
[0023] Working Principle: During operation, the crusher 2, motor 4, and fan 5 are turned on via control switch 3, and the electric heating grid 10 is energized and heated. The biomass briquettes to be dried are fed into the crusher 2. The biomass entering the crusher 2 is crushed by the crushing rollers and falls into the biomass fuel drying cylinder 7 through the feed inlet 14. The fan 5 sends outside air into the drying chamber 1 through the air inlet 15. The air entering the drying chamber 1 is heated by the electric heating grid 10 and moves upward. When the upward-moving hot air passes through the biomass fuel drying cylinder 7, it can heat and dry the crushed biomass fuel in the drying cylinder 7. During this process, the motor 4 drives the rotating shaft 8 and the turning blades 81 to rotate together, which can dry the biomass fuel by turning the blades. 81. The biomass fuel inside the biomass fuel drying cylinder 7 is turned over so that the biomass fuel can better contact with the hot air and accelerate the drying and shaping of the biomass fuel. After the biomass fuel is dried and shaped, the sealing cover 12 can be opened manually, and the electric push rod 6 can be driven by the control switch 3 to move the push block 61 backward. At this time, the arc-shaped sealing mesh plate 72 loses the support of the push block 61 and can flip down and open around the hinge axis under its own gravity. At this time, the dried and shaped biomass fuel in the biomass fuel drying cylinder 7 can fall from the discharge window at the bottom of the biomass fuel drying cylinder 7 onto the guide hopper 9 and slide down along the guide hopper 9 to the discharge nozzle 11 for automatic discharge, so that the dried and shaped biomass fuel can be collected.
