Abstract
Description
Technical Field
[0001] This utility model relates to the field of biomass fuel molding technology, and in particular to a biomass pellet fuel molding device. Background Technology
[0002] Biomass pellet fuel is the direct combustion of biomass energy, which is the processing and utilization of biomass. Direct combustion methods can be divided into four types: stove combustion, boiler combustion, garbage combustion, and solid fuel combustion. Among them, solid fuel combustion is a newly promoted technology. It solidifies biomass into a shape and then uses traditional coal-fired equipment for combustion. Its advantage is that it makes full use of biomass energy to replace coal, reduces CO2 and SO2 emissions, and is beneficial to environmental protection and control of greenhouse gas emissions.
[0003] An existing biomass pellet fuel extrusion molding device (publication number: CN217395770U) uses a sleeve and a rod to insert the rod into the sleeve. A positioning bolt passes between the sleeve and the rod, and a locking nut is used to lock and fix it. This facilitates the installation and disassembly of the extrusion blocks, allowing for the replacement of extrusion blocks of different sizes. Although this facilitates the production of pellet fuel of different sizes, the biomass pellet fuel cannot be dried in time after extrusion molding. When the biomass pellet fuel comes into contact with water vapor in the air, it is prone to moisture absorption, which is not conducive to subsequent storage and transportation, and affects processing efficiency. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a biomass pellet fuel forming device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A biomass pellet fuel forming device includes a workbench, a protective box, and a storage box. The protective box is fixedly installed on the top of the workbench. The storage box is fixedly installed on the outer wall of the protective box. A hot air duct is fixedly installed at the top of the storage box. A heating wire is fixedly installed inside the hot air duct. A fixing pipe is fixedly installed at the bottom of the hot air duct. The fixing pipe connects to the top of the storage box. A telescopic pipe is fixedly installed at the bottom end of the fixing pipe. A fixing pipe is fixedly installed at the end of the telescopic pipe away from the fixing pipe. A drying box is fixedly installed at the bottom end of the fixing pipe. An air vent is opened at the bottom end of the drying box. A hydraulic rod is fixedly installed inside the storage box. The hydraulic rod is fixedly connected to the drying box through an output shaft. A support base is provided inside the protective box. A forming frame is fixedly installed at the upper end of the support base. A heating plate is fixedly installed inside the support base. A pressure plate is provided above the forming frame.
[0007] As a further embodiment of this utility model, a fan device is fixedly installed at the upper end of the hot air duct, and a groove is opened inside the protective box, in which a cylinder is fixedly installed.
[0008] As a further embodiment of this utility model, the cylinder is fixedly connected to the top of the pressure plate via an output shaft, and the air outlets are evenly distributed on the drying box.
[0009] As a further embodiment of this utility model, a rubber block is fixedly provided between the bottom end of the support base and the inner wall of the protective box, and the cylinders are symmetrically distributed in the groove.
[0010] As a further embodiment of this utility model, the protective box is fitted with a transparent cabinet door via a hinge, and the rubber blocks are evenly distributed at the bottom of the support base.
[0011] As a further embodiment of this utility model, a control panel is fixedly installed on the workbench, and the control panel is located on one side of the protective box.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] In operation, workers first pour the biomass pellet fuel to be extruded into the forming frame, close the transparent cabinet door, and operate the control panel to turn on the heating plate to preheat the biomass pellet fuel in the upper forming frame. This reduces the moisture content of the biomass pellet fuel, which is beneficial for extrusion. Then, two sets of cylinders are activated simultaneously. The two sets of cylinders push the pressure plate down towards the forming frame through the output shaft, thereby pressing the biomass pellet fuel in the forming frame into shape. The cylinders are then extended and retracted to reset the pressure plate. The hydraulic rod is opened, and with the cooperation of the telescopic tube, the hydraulic rod pushes the drying box into the protective box. Next, the fan device is activated, and the cold air generated by the fan device enters the hot air duct. The heating wire is connected to the power supply to heat the incoming cold air. The telescopic tube delivers the hot air into the drying box. Finally, the hot air is sprayed out through several air outlets to dry the formed biomass pellet fuel below, ensuring that the formed biomass pellet fuel remains dry. Finally, workers remove the dried biomass pellet fuel for effective storage, improving production efficiency. Attached Figure Description
