Description

Technical Field

[0001] The utility model relates to the technical field of biomass fuel processing, in particular to a biomass fuel preparation device. Background Art

[0002] Biomass fuel refers to the burning of biomass materials as fuel, which mainly comes from agricultural and forestry waste, such as straw, sawdust, bagasse, rice bran, etc. During the production and processing of biomass fuel, it is necessary to use biomass fuel preparation equipment to press the straw, sawdust, bagasse, rice bran and other raw materials into regular-shaped particles for easy transportation and use.

[0003] After searching, the Chinese patent application number 202021377699.0 discloses a preparation device for biomass solid shaped briquette fuel, including a vertical tube, a slider, a pile head and a base. The vertical tube is a cylindrical structure, and the sliders are fixedly connected by a connecting plate. The bottom end of the slider is fixedly connected to the top of the sleeve. The pile head is a cylindrical hollow structure, and the pile head is composed of a handrail, a sleeve and a booster block. In the preparation device for biomass solid shaped briquette fuel, the power shaft of the servo drives the rotating shaft to make the slider rise to the set height, and then the sliding drives the pile head to impact the fuel tank along the direction of the vertical tube and the rotating shaft. After the impact, the powdered granular biomass fuel in the fuel tank is briquette-formed in the fuel tank. Because the pile head is composed of a combination of multiple groups of booster blocks, the weight of the booster block can be adjusted to adjust the impact force of the pile head, thereby realizing the functions of adjustable height of the preparation device and adjustable weight of the pile head;

[0004] The above patents still have the following deficiencies: (1) It is not convenient to process the moisture in the raw materials. Since the raw materials of biomass fuel are usually solid wastes such as straw, sawdust, bagasse, rice bran, etc., the moisture content is relatively high, which causes the raw materials to stick together and collapse, increasing the difficulty of pelletizing, or even making it impossible to produce pellets;

[0005] (2) It is inconvenient to screen the dust, resulting in the mixing of unqualified biomass fuel produced by the device with the finished biomass fuel, making the size, shape and specifications of the biomass fuel inconsistent, thus affecting the quality of the biomass fuel.

[0006] Therefore, a biomass fuel preparation device is urgently needed to solve the above problems. Utility Model Content

[0017] Through the above technical solution, the stepper motor drives the spiral impeller to rotate, so that the spiral impeller pushes the raw material into the interior of the first tube body and squeezes the raw material, so that the moisture in the raw material is discharged through the filter screen.

[0018] As a preferred technical solution of the present application, a sliding structure is formed between the partition and the first tube body, and a rotating structure is formed between the spiral impeller and the second tube body.

[0019] Through the above technical solution, the raw materials entering the interior of the connecting pipe are blocked by the partition, thereby preventing the undehydrated raw materials from entering the interior of the connecting pipe.

[0023] Through the above technical solution, the electromagnetic vibrator drives the shell to vibrate at the top of the supporting spring, so that the finished particles are discharged along the screen through the discharge port, and the defective products and powder are discharged through the chip discharge port.

[0024] As a preferred technical solution of the present application, several groups of support springs are installed on the top of the mounting seat, and the several groups of support springs are distributed at equal intervals on the bottom of the mounting seat.

[0025] Through the above technical solution, the outer shell is supported by multiple groups of supporting springs, so that the electromagnetic vibrator can easily drive the electromagnetic vibrator to vibrate.

[0026] Compared with the prior art, the utility model has the following beneficial effects:

[0027] In the scheme of this application:

[0028] 1. The spiral impeller is driven to rotate by a stepper motor, so that the spiral impeller pushes the raw material into the interior of the first tube body and squeezes the raw material, so that the moisture in the raw material is discharged through the filter screen, thereby realizing the moisture removal function of the device, facilitating the removal of excess moisture in the raw material, ensuring the strength and density of the particles, making the particles full or compact, and preventing the raw material from sticking to the interior of the device, thereby enhancing the functionality of the device;

[0029] 2. The electromagnetic vibrator drives the shell to vibrate at the top of the supporting spring, so that the finished particles are discharged through the discharge port along the screen, and the defective products and powder are discharged through the chip discharge port.
