Description

Technical Field

[0001] The present invention relates to the technical field of fuel production equipment, and particularly relates to a biomass liquid fuel production process and its equipment. Background Art

[0002] With the continuous improvement of people's living standards, the consumption of fuel and gas is increasing continuously. With the global shortage of energy resources, the fuel price has soared continuously, directly affecting industrial and agricultural production and people's daily lives. Biomass (such as agricultural wastes like straw, firewood, wood chips, bamboo chips, etc.) is a renewable resource that can be converted into biomass liquid fuel. Every year in our country, hundreds of millions of tons of agricultural wastes are burned by farmers, which not only wastes resources but also pollutes the air. Now, fossil energy is becoming increasingly exhausted, and renewable energy is a new energy that is increasingly valued by countries around the world. Moreover, biomass liquid fuel has the advantages of being environmentally friendly, having a high energy density, being easy to store and transport, etc. It can be used to replace liquefied gas and diesel in cooking utensils in restaurants and hotels. It can also be used as fuel for boilers, gas turbines, and engines. The processing of biomass fuel requires processes such as crushing, mixing, extrusion, forming, and drying.

[0003] For example, the Chinese patent publication number is CN113578096A, and the technical solution disclosed in this patent document is as follows: This biomass liquid fuel production device achieves an anti-sticking effect, is not easily affected by viscous liquid materials, can self-clean the residue, is not easily blocked, has a high filtering effect, and is not easily formed into a viscous liquid film, ensuring the liquid flow rate and improving the service performance.

[0004] Regarding the existing technology, there are the following problems:

[0005] 1. The compared patent cannot improve the filter residue, which will affect the purity of the fuel, insufficient mixing of the liquid material, and a relatively low temperature during processing. The thick liquid material will affect the mixing effect, so it will reduce the purity of the fuel or increase the thickness of the liquid material, thus affecting the production efficiency.

[0006] 2. During the process of producing and processing the fuel in the "shell" of the compared patent, the "shell" cannot form a closed space for secondary processing of the fuel, which will lead to chaotic processing steps and affect the normal process of fuel production.

[0007] 3. When filtering the liquid material in the compared patent, the filter residue remains on the filter screen, affecting the purity of the fuel, insufficient mixing of the liquid material, and a relatively low temperature during processing. The thick liquid material will affect the mixing effect. Summary of the Invention

[0056] Embodiment 4

[0057] As Figure 1 , 2As shown in Figures 3, 6, and 7, on the basis of Embodiment 2, the present invention provides a technical solution: Preferably, filter screens 8 are provided on the inner and outer walls of the treatment tank 1, and a filter screen surface cleaning structure 7 is provided on the inner and outer walls of the treatment tank 1. The filter screen surface cleaning structure 7 includes: a slider B701, a slide rail 702, and a strip-shaped block 703. The slide rail 702 is fixedly connected to the outer wall of one side of the treatment tank 1. The slider B701 is slidably sleeved on the surface of the slide rail 702. The strip-shaped block 703 is provided on the filter screen 8. A brush is provided at the bottom of the strip-shaped block 703. A feed hopper 11 is provided on the inner wall of the bottom of the treatment tank 1. An outlet 9 is communicatively provided at the bottom of the treatment tank 1. A control valve 10 is provided on the outlet 9. The slider B701 is a magnet and is magnetically connected to the strip-shaped block 703 in an opposite-sex manner. The slider B701 and the strip-shaped block 703 are arranged to cooperate with each other through the inner and outer walls of the treatment tank 1. By sliding the slider B701 on the slide rail 702, the strip-shaped block 703 inside the treatment tank 1 moves following the slider B701 due to the attraction of the magnet. The outer wall of the treatment tank 1 is provided with an opening. An electric door 3 is fixedly installed at the opening of the treatment tank 1. When the brush cleans the surface of the filter screen 8, the dust after cleaning can be discharged when the electric door 3 is opened.

By providing the filter screen 8, the upper surface of the filter screen 8 is cleaned by the brush provided below the strip-shaped block 703, preventing the filter screen 8 from being blocked due to the accumulation of impurities on its surface.

[0058] In this embodiment, by providing the filter screen surface cleaning structure 7, since the slider B701 is a magnet and is magnetically connected to the strip-shaped block 703 in an opposite-sex manner, sliding the slider B701 on the slide rail 702 causes the strip-shaped block 703 inside the treatment tank 1 to move following the slider B701 due to the attraction of the magnet. At the same time, the upper surface of the filter screen 8 is cleaned by the brush provided below the strip-shaped block 703, preventing the filter screen 8 from being blocked due to the accumulation of impurities on its surface.

[0059] Next, specifically describe the working principle of a biomass liquid fuel production process and its equipment.

[0060] As Figures 1-7As shown, start the second motor 602 from the control switch, so that the motor drives the third rotating rod 603 to rotate, and the third rotating rod 603 drives the bevel gear A 604 to rotate. Through the meshing of the bevel gear A 604 and the bevel gear B 605, the bevel gear A 604 drives the bevel gear B 605 to rotate, and the bevel gear B 605 drives the screw rod 606 to rotate. The rotating screw rod 606 is used to fully stir the liquid fuel in the upper space of the treatment tank 1. By starting the electric telescopic rod 501 from the control switch, the output end of the electric telescopic rod 501 drives the moving plate 502 to move. At this time, the slider A 507 slides in the strip groove 508. The two sections of teeth provided on the moving plate 502 drive the gear A 503 and the gear B 506 to rotate, so that the gear A 503 and the gear B 506 drive the two first rotating rods 504 to rotate respectively, and the two first rotating rods 504 drive the two opening and closing plates 509 to open and close respectively, so that the fully stirred liquid fuel falls onto the lower filter screen 8. After passing through the filter screen 8, the impurities in the liquid fuel will be filtered out. The filtered liquid fuel will pass through the feeding hopper 11 and the discharge port 9, and then be discharged through the setting of the control valve 10. Since the slider B 701 is a magnet and is magnetically connected to the strip block 703 in an opposite-sex manner, the slider B 701 is slid on the slide rail 702, so that the strip block 703 inside the treatment tank 1 moves along with the slider B 701 due to the magnetic attraction. At the same time, the brush provided below the strip block 703 is used to clean the upper surface of the filter screen 8, avoiding the blockage of the filter screen 8 caused by the accumulation of impurities on the surface of the filter screen 8.
