Abstract
Description
Technical Field
[0001] This utility model relates to the field of biomass pellet fuel preparation, and specifically to an apparatus for preparing seaweed fiber biomass pellet fuel. Background Technology
[0002] Oceans cover 70% of the Earth's surface and are home to a vast array of marine plants. These plants contain various amino acids, vitamins, minerals, and a large amount of non-nitrogenous organic compounds, as well as many bioactive substances that promote livestock and poultry growth, enhance immunity, and improve stress and viral resistance. However, the utilization of marine plants is currently inadequate and not fully realized, leading to a waste of marine plant resources in actual production processes. Furthermore, the unutilized portions become industrial waste, causing environmental problems.
[0003] In the production of hydrophilic colloids such as carrageenan and agar from marine red algae like *Euphorbia milii* and *Gracilaria lepidophylla*, the algae undergoes impurity removal and pretreatment before being boiled in water and filtered. The resulting clear liquid is the refined carrageenan and agar solution. The main component of the obtained algae solids is algae cellulose. Traditionally, this algae fiber becomes solid waste requiring treatment, increasing the burden on enterprises and raising production costs. Existing biomass fuels are all prepared from terrestrial materials, and traditional plant-based biomass fuels require the addition of binders during the pelleting process to achieve pelleting.
[0004] Therefore, in order to overcome the shortcomings of the existing technology, it is necessary to design a simple seaweed fiber biomass pellet fuel preparation device. Utility Model Content
[0005] This invention provides a device for preparing seaweed fiber biomass pellet fuel to address the problems of existing technologies.
[0006] The purpose of this utility model can be achieved through the following technical solution: A seaweed fiber biomass pellet fuel preparation device includes: a seaweed pretreatment device for washing, crushing and dehydrating seaweed;
[0007] The algae boiling device is used to boil pretreated seaweed to extract seaweed gum solution.
[0008] A pressing and filtering device is used to press and filter seaweed solids after boiling to separate and extract the adhesive and solids; the pressing and filtering device includes an electric plate and frame and a filter screen platform, the electric plate and frame is set above the filter screen platform, and an electric push plate is provided on one side of the filter screen platform;
[0009] Granulation device, used to granulate seaweed solids;
[0010] The drying device is used to dry the granulated seaweed particles to reduce their moisture content.
[0011] Packaging equipment for metering and packaging dried seaweed granules.
[0012] In a further improvement, the pressing and filtering device includes a collection box disposed below the filter platform.
[0013] A further improvement is that the seaweed pretreatment device includes a washing machine, a crusher, and a dewatering machine arranged in sequence according to the process steps.
[0014] A further improvement is that the glue-cooking device includes a glue-cooking pot and a stirrer disposed inside the glue-cooking pot.
[0015] In a further improvement, the granulation device includes a feeder and a granulator arranged sequentially in the process steps. The feeder is used to transport the crushed seaweed solids to the granulator.
[0016] Compared with existing technologies, the beneficial effects of this novel seaweed fiber biomass pellet fuel preparation device are as follows:
[0017] This device effectively utilizes the seaweed fiber solids generated during the production of hydrophilic colloids such as carrageenan and agar from marine red algae. Previously, this seaweed fiber was considered solid waste, requiring specialized treatment, which not only wasted resources but also increased processing costs and environmental burden for enterprises. This device transforms seaweed fiber into economically valuable biomass pellet fuel, eliminating the need for seaweed solid waste treatment and creating new profit growth points for enterprises by manufacturing biomass pellets. It also reduces the environmental damage caused by over-reliance on terrestrial resources. Furthermore, the seaweed fiber can be pelletized without the addition of binders during production, further reducing material costs and effectively controlling the production cost of biomass pellet fuel.

[0025] Seaweed pretreatment device 1 is used for washing, crushing and dehydrating seaweed;
[0026] The gelling device 2 is used to boil the pretreated seaweed to extract seaweed gel.
[0027] The pressing and filtering device 3 is used to press and filter the seaweed solids after boiling to separate and extract the glue and solids; the pressing and filtering device 3 includes an electric plate frame 31 and a filter platform 32, the electric plate frame 31 is arranged above the filter platform 32, and an electric push plate 33 is provided on one side of the filter platform 32.
[0028] Granulation device 4 is used to granulate seaweed solids;
[0029] Drying device 5 is used to dry the granulated seaweed particles to reduce their moisture content.
[0030] Packaging device 6 is used for metering and packaging dried seaweed granules.
[0031] As a further preferred embodiment, the pressing and filtering device 3 includes a collection box 34, which is disposed below the filter platform 32.
[0032] As a further preferred embodiment, the seaweed pretreatment device 1 includes a washing machine 11, a crusher 12 and a dewatering machine 13 arranged in sequence according to the process.
[0033] As a further preferred embodiment, the glue cooking device 2 includes a glue cooking pot 21 and a stirrer 22 disposed inside the glue cooking pot 21.
[0034] As a further preferred embodiment, the granulation device 4 includes a feeder 41 and a granulator 42, wherein the feeder 41 is used to transport the crushed seaweed solids to the granulator 42.
[0035] like Figure 1 The operation process of this utility model is shown below:
[0036] I. Seaweed Pretreatment Stage
[0037] Cleaning: First, the collected seaweed is placed in the cleaning machine 11 of the seaweed pretreatment device. The water flow is used to thoroughly clean the mud, sand, impurities and other debris attached to the surface of the seaweed, removing the dirt and ensuring the purity of the raw materials for subsequent processing.
[0038] Crushing: After washing, the seaweed enters the crusher 12, where it is broken into smaller fragments through mechanical shearing and compression. The purpose of this step is to increase the contact area between the seaweed and the subsequent processing medium, facilitating the release of the seaweed's internal components and the subsequent gelling process.
[0039] Dehydration: The crushed seaweed fragments enter the dehydrator 13, where excess water is removed from the seaweed by centrifugal force or pressure, reducing the water content of the seaweed and providing a suitable material state for the subsequent glue-making process, reducing the amount of water evaporation during the glue-making process, and improving the glue-making efficiency.
[0040] II. Boiling Stage
[0041] Preparation for boiling: The pre-treated seaweed fragments are put into the boiling pot 21 of the boiling device.
[0042] Cooking process: Turn on the stirrer 22 inside the cooking pot. Under the stirring action of the stirrer, the seaweed fragments and water in the cooking pot are thoroughly mixed. At the same time, heat the cooking pot to allow the seaweed to undergo a cooking reaction under high temperature and stirring conditions. During the cooking process, the gelatinous components in the seaweed gradually dissolve in the water to form a gel, while solids such as seaweed fibers remain in the pot.
[0043] Gum Extraction: After the gel is boiled, the mixture in the boiling pot is initially separated, and the liquid portion containing the gel is taken out for subsequent refining processes of hydrophilic colloids such as carrageenan and agar, thus realizing the effective extraction and utilization of seaweed gum.
[0044] III. Pressing and Filtration Stage
[0045] Pressing preparation: Transfer the remaining seaweed solids after boiling to the filter platform 32 of the pressing and filtering device. The filter platform is equipped with a filter screen, which can perform preliminary filtration of the seaweed solids, intercepting larger solid particles, while allowing liquid to flow out through the filter screen.
[0046] Pressing operation: Activate the electric plate and frame 31, which applies downward pressure to press the seaweed solids on the filter platform. Under pressure, residual gum and water in the seaweed solids are further squeezed out and flow through the filter into the collection box 34 below.
[0047] Solid-liquid separation: After pressing and filtration, most of the colloid and water in the seaweed solids are separated and collected in the collection box. The remaining seaweed solids on the filter platform are mainly composed of seaweed cellulose, with a significantly reduced water content, providing suitable material conditions for subsequent granulation operations. They are then pushed out by the electric pusher plate 33.
[0048] IV. Granulation Stage
[0049] Feeding: The pressed and filtered seaweed solids are fed into the feeder 41 of the granulation device. The feeder delivers the seaweed solids evenly to the feed inlet of the granulator 42 at a certain speed and quantity.
[0050] Granulation: Inside the granulator, seaweed solids are processed into granules of a certain shape and size under mechanical extrusion and shearing. Since carrageenan, agar, and sodium alginate naturally contained in seaweed are excellent binders, no additional binders are needed during the granulation process to achieve good molding results. This not only simplifies the process and reduces production costs, but also avoids the environmental pollution problems that binders may cause.
[0051] V. Drying Stage
[0052] Drying preparation: The granulated seaweed granules are fed into drying device 5. The drying device can use various drying methods such as hot air drying and microwave drying. The appropriate drying process is selected according to the actual production needs and the characteristics of the seaweed granules.
[0053] Drying Operation: The seaweed pellets are dried within the drying unit by controlling parameters such as drying temperature and time. During the drying process, the moisture in the seaweed pellets gradually evaporates, reducing their moisture content to meet the requirements of biomass pellet fuel standards.
[0054] VI. Packaging Stage
[0055] Metering and Packaging: The dried seaweed granules enter the packaging device 6, which accurately measures the seaweed granules. They can be packaged into small packages for home cooking or winter heating, or used as fuel for industrial boilers in combination with coal and natural gas to reduce fuel costs.
[0056] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
