[0028] In the existing biomass fuel soaking and deashing technology, the device used to achieve biomass fuel deashing pretreatment is basically a fixed circular device or a square device. Such a device generally uses a spray soaking liquid to deash the biomass fuel, and the biomass fuel and the soaking liquid cannot be effectively mixed, resulting in a relatively low deashing efficiency of the biomass fuel. Moreover, since most soaking liquids are volatile, when such a device is used to deash the biomass fuel, the soaking liquid is easily volatilized to the outside, resulting in a decrease in the concentration of the soaking liquid, which greatly reduces the deashing efficiency and deashing effect of the biomass fuel.

[0029] To this end, the present invention provides a drum device for pretreatment of biomass fuel by soaking, washing and deashing, which can improve the deashing efficiency and deashing effect of the biomass fuel.

[0030] Reference Figures 1 to 3 In some embodiments of the present invention, a drum device for pretreatment of biomass fuel soaking and deashing includes a drum body and a driving assembly, wherein a receiving cavity is provided inside the drum body, and the receiving cavity can be used to place the biomass fuel and the corresponding soaking liquid. The driving assembly is used to drive the drum body to rotate, so that the biomass fuel and the soaking liquid in the receiving cavity of the drum body can be fully mixed and contacted during rolling, which greatly improves the deashing efficiency and deashing effect of the biomass fuel.

[0031] The drum device for soaking and deashing pretreatment of biomass fuel in the embodiment of the present invention, when using the drum device to soak and deash the biomass fuel, firstly put the biomass fuel and the corresponding soaking liquid into the accommodating chamber of the cylinder, and then start the driving component so that the driving component can drive the cylinder to rotate. At this time, the biomass fuel and the soaking liquid rotate and roll in the accommodating chamber with the rotation of the cylinder, so that the biomass fuel and the soaking liquid can be fully mixed. Compared with the traditional device that uses the soaking liquid to spray the biomass fuel for deashing pretreatment, the drum device changes the process of the biomass fuel soaking pretreatment stage, and strengthens the solid-liquid reaction of the biomass fuel and the soaking liquid by rotating and rolling, thereby improving the deashing efficiency of the biomass fuel and reducing the time of the deashing pretreatment. Moreover, the biomass fuel and the soaking liquid are placed in a closed accommodating chamber for mixing, which can effectively reduce the impact of the soaking liquid volatilizing to the outside world, thereby further improving the deashing efficiency and deashing effect of the biomass fuel.

[0032] Reference Figure 1It can be understood that in some embodiments of the present invention, the cylinder includes a barrel 13 and a barrel cover 1, the barrel 13 is placed in a horizontal direction, and the number of barrel covers 1 is two. The two barrel covers 1 can be respectively sealed at the two ends of the barrel 13 along the axial direction by welding or bonding, so that the barrel cover 1 and the barrel 13 can be surrounded to form a receiving cavity. Specifically, the barrel 13 is roughly cylindrical, and the barrel 13 can be made of a plastic polymer material. For example, the barrel 13 can be made of acrylic. Acrylic has good acid and alkali resistance, so that it can still maintain a stable structure under the immersion of the soaking liquid, which is conducive to maintaining the long-term stable operation of the penetration device. Of course, the barrel 13 made of acrylic also has good transparency, so that the staff can intuitively know the status of the biomass fuel and the soaking liquid in the receiving cavity, so as to facilitate the staff to take corresponding operations. Of course, in order to make the biomass fuel more fully contact with the soaking liquid in the accommodating cavity, the inner wall of the cylinder body 13 can be provided with a protruding structure, which can make the soaking liquid generate a local vortex during the rotation of the cylinder body, and the rotation direction of the vortex is inconsistent with the rotation direction of the cylinder body, so that the soaking liquid can flush and mix the biomass fuel in more directions, which is conducive to the faster precipitation of the ash of the biomass fuel, thereby further improving the efficiency of deashing the biomass fuel. Of course, a plurality of protruding structures can be provided, and a plurality of protruding structures can be staggered and separated along the rotation direction of the cylinder body, so as to better promote the deashing of the biomass fuel.

[0033] It is understandable that, in order to enable the drive assembly to drive the barrel to rotate, in some embodiments of the present invention, the drive assembly includes a drive shaft 10, and the drive shaft 10 can drive the barrel cover 1 to rotate. For example, the outer wall of the drive shaft 10 can be provided with a transmission tooth, and the outer wall of the barrel cover 1 can be provided with a driven tooth, and the transmission tooth and the driven tooth are meshed, so that the drive shaft 10 can drive the barrel cover 1 to rotate. Of course, other transmission structures can also be used between the drive shaft 10 and the barrel cover 1 to transmit power, for example, a belt drive or a chain drive can be used between the drive shaft 10 and the barrel cover 1.

[0034] It is understandable that in some embodiments of the present invention, the drive assembly further includes a drive motor 12 and a base. The base may be a frame structure, which may include a panel and a support frame located inside the panel. The drive motor 12 may be disposed inside the panel, thereby realizing concealed installation and reducing the impact of the outside world on the drive motor 12. The drive shaft 10 may be rotatably mounted on the upper end of the base. For example, a rolling bearing may be installed on the panel, and the drive shaft 10 may be fixedly mounted on the inner ring of the rolling bearing, so that the drive shaft 10 may rotate relative to the base. The drive motor 12 is connected to the drive shaft 10 in a transmission manner. For example, a chain transmission may be adopted. The drive motor 12 may drive the drive shaft 10 to rotate through the tank chain 11. In order to make the overall structure of the device simpler and lighter, the barrel can be placed on the upper end of the base, and the outer diameter of the barrel cover 1 is larger than the outer diameter of the barrel body 13, so that the barrel cover 1 can abut against the upper end of the drive shaft 10. Under the gravity of the barrel and the soaking liquid and biomass fuel in the accommodating cavity, the barrel cover 1 can be closely attached to the upper surface of the drive shaft 10, so that there is no need to adopt other transmission structures. The drive shaft 10 can drive the barrel cover 1 to rotate by friction, thereby rotating the barrel. Specifically, the barrel cover 1 can be made of an elastic structure, such as rubber. Under the action of gravity, the barrel cover 1 is closely attached to the upper end of the drive shaft 10, and because the barrel cover 1 is elastic, the barrel cover 1 can be deformed and better attached to the upper end of the drive shaft 10, so that the contact area between the barrel cover 1 and the drive shaft 10 is larger, which is conducive to the drive shaft 10 driving the barrel cover 1 to rotate by friction, thereby rotating the barrel to fully mix the biomass fuel and the soaking liquid, and realizing rapid deashing.

[0035] It should be noted that, in order to make the cylinder body rotate more smoothly, in some embodiments of the present invention, the driving assembly also includes a support shaft 9, which can be rotatably mounted on the upper end of the base and spaced apart from the driving shaft 10, and the cylinder cover 1 can abut against the support shaft 9, so that when the cylinder cover 1 rotates, the support shaft 9 can support the cylinder cover 1 in rotation, so that the force on the cylinder cover 1 is more balanced, which is conducive to improving the stability of the cylinder body rotation. Specifically, the support shaft 9 can also be rotatably mounted on the enclosure of the base through a rolling bearing, and the outer diameter of the support shaft 9 can be the same as or different from the outer diameter of the driving shaft 10, and can be specifically set according to actual needs.

[0036] It is understandable that, in order to facilitate the placement and removal of materials such as soaking liquid and biomass fuel into and out of the accommodating chamber, in some embodiments of the present invention, at least one of the barrel covers 1 is provided with a material port, and the barrel cover 1 is also provided with a material door 2 movably sealed at the material port. When it is necessary to put materials into the accommodating chamber, the operator can open the material door 2, and then put the soaking liquid, biomass fuel and other materials into the accommodating chamber from the material port, and finally close the material door 2. Similarly, when it is necessary to take out the materials in the accommodating chamber, the operator can open the material door 2, and then take the materials out of the accommodating chamber, which is very convenient to operate.

[0037] It can be understood that in order to prevent the material in the accommodating chamber from leaking from the accommodating chamber to the outside of the cylinder, in some embodiments of the present invention, a sealing ring is provided on the outer edge of the material port. The sealing ring can be made of rubber or silicone or other elastic materials. Of course, the sealing ring also has good acid and alkali resistance. When the material door 2 is sealed at the material port, the inner wall of the material door 2 can abut against the sealing ring, so that the material door 2 can seal the material port, so that when the cylinder rotates, the soaking liquid and the material in the accommodating chamber can be fully mixed with the rotation of the cylinder and quickly deashed, and at the same time, the soaking liquid can be prevented from leaking out of the material port, thereby avoiding the problem of low deashing effect caused by leakage and volatilization of the soaking liquid during the deashing process, further improving the deashing effect of the device.

[0038] It should be noted that a certain vibration will be generated when the cylinder rotates. At this time, the material door 2 is easily loosened due to the vibration, resulting in failure of the seal on the material port. For this reason, in some embodiments of the present invention, the cylinder is also provided with a limiting mechanism, and the limiting mechanism can lock the material door 2 to the material port, so that during the rotation of the cylinder, the material door 2 can also remain firmly sealed on the material port, thereby effectively preventing the soaking liquid in the accommodating cavity from leaking to the outside and affecting the deashing effect of the biomass fuel.

[0039] Reference Figure 3Specifically, in some embodiments of the present invention, the limiting mechanism includes a fixed rod and a rotating block 3, the fixed rod 14 is installed on the cylinder cover 1, the rotating block 3 can be rotatably sleeved on the fixed rod 14, and the rotating block 3 can rotate around the fixed rod 14 to press or loosen the material door 2. The end of the cylinder cover 1 away from the cylinder body 13 is provided with two spaced clamping blocks 4, and the clamping blocks 4 are provided with a clamping hole adapted to the fixed rod 14. The fixed rod 14 is clamped on the clamping block 4 by inserting the clamping hole, so that the fixed rod 14 can be fixedly installed on the end of the cylinder cover 1. One end of the rotating block 3 extends outward, and the other end is provided with a bayonet. The rotating block 3 can be sleeved on the outer wall of the fixed rod 14 through the bayonet, and can rotate relative to the fixed rod 14, so that the end of the rotating block 3 protruding outward can abut against the material door 2 to lock the material door 2 at the material port, or by rotating the rotating block 3 in the opposite direction, the end of the rotating block 3 protruding outward can be away from the material door 2, so that the material door 2 can be removed from the material port conveniently. Of course, the rotating block 3 can be made of a material with a certain elasticity, such as a rubber block, so that the rotating block 3 can be more easily connected to the fixed rod through the bayonet, and when the end of the rotating block 3 abuts against the material door 2, it can be deformed by force and better fit against the material door 2. The fixed rod 14 can be made of a material with a relatively high strength, such as stainless steel or other metal materials.

[0040] Reference Figure 2 It can be understood that in order to facilitate the relevant operation control of the drive component, in some embodiments of the present invention, the drive component also includes an operation panel, and the operation panel is provided with a first knob 6, a second knob 7 and a third knob 8. The first knob 6 is used to adjust the rotation speed of the cylinder, the second knob 7 is used to adjust the rotation time of the cylinder, and the third button is used to adjust the direction of the cylinder. Of course, the operation panel is also provided with an operation indication light. When performing the pretreatment of soaking and deashing of biomass fuel, the operator can adjust the rotation speed of the drive motor 12 through the first knob 6, thereby adjusting the rotation speed of the cylinder; and can adjust the running time of the drive motor 12 through the second knob 7, thereby adjusting the rotation time of the cylinder; and can adjust the direction of the drive motor 12 through the third knob 8, thereby adjusting the direction of the cylinder, so that the drum device of the present invention can more fully mix the biomass fuel in the accommodating cavity with the soaking liquid, strengthen the solid-liquid reaction between the two, and improve the deashing efficiency of the biomass fuel.

[0041] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
