Description

Technical Field

[0001] The invention relates to the field of mechanical technology, in particular to a preparation and molding device suitable for a porous wood-based carrier. Background Art

[0002] In recent years, people have paid more and more attention to the development and utilization of natural biomass materials, and new structural wood has become a hot research topic. Due to the special structure and composition of wood, selectively removing lignin and hemicellulose from wood, destroying its thin-walled cells, retaining the three-dimensional morphological structure, and thus constructing a porous structural wood substrate is a popular research direction for the utilization of wood resources. In existing studies, this type of porous structural wood substrate can be made into wood sponges for sewage purification; it can also be made into wood film adsorption materials to adsorb metal ions in sewage; it can also be made into transparent wood by filling resin and applied to the home decoration and construction industry; or it can be carbonized and used as a high-performance strain sensor for human motion or health monitoring. Therefore, the construction of functional composite materials using porous structural wood as a substrate has great potential utilization value in the fields of construction, electronic devices, optoelectronic materials, bionic materials, and even textile materials, and can provide corresponding technical support for the research of wood-based composite materials.

[0003] Anaerobic digestion can produce biogas from organic wastes such as residual sludge, kitchen waste, livestock manure and lignocellulose, while reducing the pollution caused by organic wastes to the environment, which has good environmental and economic benefits. Based on the advantages of carbon neutrality, renewable and abundant sources, lignocellulosic organic wastes are considered to be one of the ideal substrates for anaerobic digestion and methanogenesis. However, due to the tight structure formed by the articulation of cellulose, hemicellulose and lignin, anaerobic digestion of lignocellulosic organic wastes has the disadvantages of slow hydrolysis rate, long digestion cycle and low methane production.

[0004] Anaerobic bacteria play an important role in many bioengineering and environmental protection applications, especially in the fields of sewage treatment and anaerobic fermentation. The efficient reproduction and growth of anaerobic bacteria directly affect the working efficiency and effect of the system. In order to support the growth of anaerobic bacteria, a suitable carrier must be provided to enable them to attach, reproduce and obtain continuous nutrient supply. At present, most of the carriers used in the biofilm sewage treatment process are commercial organic plastic carriers and inorganic ceramsite carriers, which not only have high operating costs, but also consume a lot of energy in the carrier production process. The ideal biofilm carrier should have the characteristics of low price, good mechanical strength, resistance to biodegradation, large specific surface area and strong biological affinity.

[0005] In addition, traditional anaerobic carriers usually use natural materials or synthetic materials, but often have the following problems: the preparation of traditional carriers mostly relies on manual operation, resulting in low production efficiency and unable to meet the needs of large-scale applications. At the same time, the processing accuracy of the pore structure is difficult to guarantee, which affects the growth space of the bacterial community. During the inoculation of bacterial strains and the filling of nutrients, it is difficult to achieve uniform distribution, resulting in insufficient nutrient supply in some areas, and the reproduction of bacterial strains is restricted, affecting the overall working performance of the system. In addition, the current preparation process has a low level of automation, and it is impossible to achieve precise processing and quantitative filling of carrier materials. The process adaptability is insufficient and it is difficult to flexibly adjust according to specific needs, resulting in cumbersome operation and low efficiency.

[0006] In view of this, research and improvement are carried out on the existing problems, and a preparation and molding device suitable for porous wood-based carriers is provided to solve the current problems. The purpose is to achieve the purpose of solving the problems and improving the practical value through this technology. Summary of the invention

DETAILED DESCRIPTION

[0022] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0023] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0024] The following is combined with Figure 1-Figure 8 Some embodiments of the present invention provide a preparation and molding device suitable for a porous wood-based carrier. Example 1

[0025] The device in this embodiment is mainly used for small-scale experimental production of anaerobic bacteria carriers, and is described in detail as follows: The basic structure of the device includes: a conveying component 100 , a substrate feeding component 400 , a bacterial liquid feeding component 500 , and a punching component 200 and a vibrating filler 300 fixed on the surface of the conveying component 100 .

[0026] The conveying assembly 100 includes an adjusting frame 110 and a clamping conveyor belt 120 slidably mounted on the surface of the adjusting frame 110. The surface of the adjusting frame 110 is provided with a screw slide 111 for driving the two clamping conveyor belts 120 to slide. The positions and spacings of the two clamping conveyor belts 120 can be adjusted to adapt to wood-based carriers of different sizes, and the clamping positioning of the wood-based carrier can be maintained to avoid displacement during punching and filling operations.

[0027] The punching assembly 200 includes a punching seat 210, a pressing plate 220, a punch seat 230, and a synchronous toothed disc 240 and a drill rod 260 rotatably mounted inside the punch seat 230. The multiple drill rods 260 are evenly arranged to form a matrix, and the gears on the top are in transmission engagement with the inner side of the synchronous toothed disc 240, which can synchronously drive the multiple drill rods 260 to perform rotational punching.

[0028] The vibrating filler 300 includes a driving seat 310, a driving rod 320, a feeding head 330 and a polarizer 340 installed inside the driving seat 310. The polarizer 340 is used to drive the feeding head 330 to vibrate at a high frequency so that it can maintain good contact with the surface of the wood-based carrier. The bottom of the feeding head 330 is provided with a discharge port 331 for feeding the nutrient carrier or bacterial solution into the pores of the wood-based carrier. The carrier feeding component 400 and the bacterial solution feeding component 500 respectively transport the nutrient carrier and the bacterial solution into the pores in a time sequence through the feeding port 332.

[0029] The nutrient carrier feeding system nutrient carrier feeding assembly 400 is composed of a loading hopper 410, a lifting conveyor belt 420 and a guide ladder 430. The bottom surface of the lifting conveyor belt 420 is provided with an adjustable arc bar to control the inclination of the lifting conveyor belt 420 and adjust the delivery amount of the nutrient carrier. The material is lifted by evenly distributed inclined guide plates 421, which can ensure that the nutrient carrier is evenly distributed during the feeding process.

[0030] The controller of the device is connected to the substrate feeding assembly 400 and the bacterial solution feeding assembly 500, and can accurately control their working sequence to achieve the sequential injection of the nutrient substrate and the bacterial solution.

[0031] When the equipment is in operation, the surface of the wood-based carrier is first punched by multiple drill rods 260 of the punching assembly 200, and the synchronous gear system of the synchronous gear disc 240 ensures that the multiple drill rods 260 rotate synchronously to complete efficient and uniform pore processing. Subsequently, the carrier feeding assembly 400 controls the delivery amount of the nutrient carrier by adjusting the inclination of the inclined guide plate 421, and the vibrating filler 300 presses the material into the pores. Finally, the bacterial liquid is quantitatively added through the bacterial liquid feeding assembly 500 to ensure that the bacterial colony in the pores is evenly distributed.

[0032] Extension and supplement: The device can flexibly adapt to wood-based carriers of different sizes by adjusting the sliding device of the adjustment frame 110, making it suitable for a variety of experimental conditions. Since the device integrates the functions of pore processing, nutrient carrier delivery and bacterial liquid filling, it can complete the preparation of multiple carriers in a short time, which is suitable for small-scale experimental production. Example 2

[0033] The device in this embodiment is suitable for large-scale industrial production of anaerobic bacteria carriers, and the structure is further optimized, as described in detail as follows: The basic structure of the device is similar to that of Example 1, but more automated control components are added. In the structure of the transmission assembly 100, the sliding adjustment mechanism of the adjustment frame 110 and the clamping conveyor belt 120 is further optimized so that it can automatically adapt to wood-based carriers of different shapes and sizes. By integrating an automated sensor system on the screw slide 111, the size and shape of the carrier can be detected in real time, and the spacing of the clamping conveyor belt 120 can be automatically adjusted to meet different production requirements.

[0034] The punching assembly 200 structure is provided with a synchronous toothed disc system of multiple synchronous toothed discs 240 and drill rods 260, which ensures that the surfaces of multiple carriers can be processed simultaneously in large-scale production, significantly improving production efficiency. The rotation speed and punching depth of multiple drill rods 260 can be synchronously adjusted through the control system to ensure processing accuracy.

[0035] In the substrate feeding assembly 400 and the bacterial solution feeding assembly 500 of the bacterial solution feeding system, the structure of the device is further optimized.

[0036] The lifting conveyor belt 420 in the carrier feeding assembly 400 is provided with an automatic inclination adjustment device, which can adjust the inclination according to the real-time monitoring data to achieve more accurate feeding control. The inclined guide plate 421 channel has an anti-blocking design to ensure that there will be no uneven feeding or blockage problems during long-term continuous operation.

[0037] In the bacterial liquid feeding assembly 500, the bacterial liquid is added by a high-precision pump control system, which can monitor the flow rate of the bacterial liquid in real time and automatically adjust the delivery speed according to the size and number of pores to ensure uniform addition of the bacterial liquid.

[0038] The controller in this embodiment can not only control the sequential delivery of the nutrient carrier and the bacterial solution, but also adjust the working state of each component according to the real-time feedback of the production line. By connecting to the central control system, the entire production process can be remotely monitored and operated.

[0039] Supplementary information: The device of this embodiment is particularly suitable for large-scale industrial production. It has a higher degree of automation and is more flexible. It can adapt to wood-based carriers of different sizes and shapes and achieve efficient production through precise control. The anti-blocking design and real-time monitoring system in the device ensure the stability of long-term continuous operation and are suitable for large-scale anaerobic culture carrier production needs.

[0040] Through the above two specific embodiments, the present invention demonstrates various application forms of the anaerobic bacteria carrier preparation device from small-scale experiments to large-scale industrial production. Whether in terms of the accuracy of the punching process or the quantitative delivery control of the nutrient carrier and the bacterial solution, the device of the present invention can meet the production environment with different requirements, has a high degree of automation and flexibility, can effectively improve production efficiency, and ensure the preparation quality of the anaerobic bacteria carrier.

[0041] The working principle and use process of the present invention: The porous wood-based carrier preparation device suitable for the growth and reproduction of anaerobic bacteria of the present invention realizes the multi-step processing of the wood-based carrier through automated integration. Its core working principle is as follows: Multi-pore punching: The equipment punches holes on the wood-based carrier through the punching assembly 200. Specifically, multiple drill rods 260 are rotated synchronously through the synchronous toothed disc 240, and the punching kinetic energy of the drill rods is converted into rotational kinetic energy to evenly punch holes on the surface of the wood-based carrier. The punching process is controlled by an automatic control system to ensure the consistency of the pore size and pore distribution.

[0042] Filling of nutrient carrier: After the drilling is completed, the system evenly and quantitatively transports the solid powdered granular material mixed with the prepared plant ash and organic humus through the carrier feeding assembly 400, and presses it into the pores of the wood-based carrier through the vibrating filler 300. Through the uniform distribution of the inclined guide plate 421 and the adjustment of the inclination of the lifting conveyor belt 420, the system can control the feeding amount each time to ensure that the nutrient carrier evenly fills the pores.

[0043] Bacterial solution filling: After the nutrient carrier is filled, the system starts the bacterial solution feeding component 500 bacterial solution feeding component to inject the anaerobic bacterial solution into the pores. The filling process is coordinated by the controller to ensure that the nutrient carrier and the bacterial solution are sequentially added, and the amount of bacterial solution is quantitatively added according to the size and number of pores to ensure that the anaerobic bacteria are evenly distributed in the pores.

[0044] Timing control: The core control system of the device electrically connects the input ends of the substrate feeding component 400 and the bacterial solution feeding component 500 to control the working timing of the two, ensuring that the nutrient substrate and bacterial solution are added according to the predetermined steps and sequence, thereby avoiding material waste and uneven distribution.
