Description

Technical Field

[0001] This utility model belongs to the field of biomass film production technology, and in particular relates to a jacket device for producing biomass films. Background Technology

[0002] The production equipment for biomass membranes varies depending on the material type and process, but typically includes key steps such as raw material pretreatment, slurry mixing, film formation, drying and curing, post-treatment, and auxiliary systems. In the raw material pretreatment stage, crushers or grinders are used to pulverize biomass raw materials (such as straw, starch, and cellulose) to a suitable particle size. Subsequently, drying equipment (such as fluidized bed or drum dryers) is used to reduce the moisture content, and sieving equipment removes impurities to ensure raw material uniformity. The slurry mixing system is one of the core steps in biomass membrane preparation, involving chemical treatment of the raw materials in a reactor or digester (such as alkali treatment of cellulose), or uniform mixing of the biomass slurry with plasticizers and modifiers (such as glycerol and citrate esters) using a high-speed mixer. Some processes may also employ enzymatic hydrolysis equipment to optimize raw material properties through biological methods (such as cellulosic hydrolysis). Based on the above production, the biomass membrane needs to be extruded under pressure to form a suitable film, completing the film production. However, the production equipment for biomass membranes still has the following drawbacks in actual use:

[0003] During the production process of biomass film, when the film is conveyed into the extrusion equipment, it comes into contact with the inner wall of the equipment. In the initial operation, the temperature inside the device is uneven, which can cause material blockage and excessive waste in the early stage, affecting the effective production time and causing material waste.

[0004] Secondly, in order to control the entire biomass film production process, production equipment is needed for production, and temperature and pressure are monitored by monitoring equipment. However, the probes of the monitoring equipment are directly installed at the valve positions, which will differ from the actual production positions, affecting the accuracy of monitoring during the production process. Utility Model Content

[0005] The purpose of this utility model is to provide a jacketed device for producing biomass films. By setting up a support plate, an outer jacket, and an insulation pipe, it solves the problems of long waiting time for temperature adjustment in biomass film production equipment, which easily leads to material waste, and the inaccurate monitoring of pressure and temperature during the flow of adhesive liquid by the monitoring equipment.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a jacketed device for producing biomass film, comprising a support plate, an outer jacket, and insulation pipes. The outer jacket is fixed to the top of the support plate, and an inner jacket is fixed to the inner edge of the outer jacket. A spray lip is fixed to the inner wall of the inner jacket. The two ends and the bottom of the outer and inner jackets are closed. A sealing plate is fixed to one end of the spray lip, and a sealing plate is fixed to the other end of the spray lip away from the sealing plate. Two insulation pipes are fixed through the top of the outer and inner jackets. During operation, the support plate fixes the structure of the outer jacket and other formed biomass film on its top. At the same time, the outer and inner jackets cooperate to transport the adhesive liquid that has been heated and formed into biomass film. Probes for measuring temperature and pressure are installed through the insulation pipes.

[0008] Furthermore, the bottoms of both sealing plate one and sealing plate two are fixed to the top of the support plate, and an insulation shell is fixed between sealing plate one and sealing plate two. The bottom of the insulation shell is fixed to the top of the support plate, and the insulation shell provides insulation to the outer jacket to reduce heat loss from the outer side of the outer jacket.

[0009] Furthermore, an output slit is provided on the top of the support plate between the first sealing plate and the second sealing plate along the center line parallel to the long side. A glue inlet is fixedly provided in the lower part of the first sealing plate. The glue inlet is connected to the inside of the spray lip. The output slit outputs the glue to form a biomass membrane.

[0010] Furthermore, the outer jacket, inner jacket, and spray lip are all provided with through openings corresponding to the positions of the two insulation pipes. The bottom end of the insulation pipe is fixed in the through opening, and the insulation pipe is connected to the spray lip. The outer jacket, inner jacket, and spray lip fix the insulation pipe through the through opening.

[0011] Furthermore, an output pipe is fixedly connected to the top of the outer jacket near the edge of the second sealing plate, and an input pipe is fixedly connected to one side of the outer jacket near the short side of the first sealing plate. A fixing hole is provided in the second sealing plate corresponding to the positions of the input pipe and the output pipe. The input pipe and the output pipe are fixedly connected in the fixing hole and extend out. The input pipe transports the heating fluid between the outer jacket and the inner jacket and outputs it through the output pipe to heat the adhesive liquid passing through the spray lip.

[0012] Furthermore, a fixing port is provided on the top of the insulation shell corresponding to the positions of the two insulation pipes. The insulation pipes are fixed inside the fixing port. An installation plate is fixed at the upper edge of the insulation pipe. The fixing port on the insulation shell fixes the insulation pipe, and the installation plate is used to install and set up a device for measuring temperature and measuring adhesive pressure.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of long waiting times for temperature adjustment in biomass film production equipment, which easily leads to material waste, by setting up a support plate, outer jacket, and insulation pipe. After installing the pipe connector for conveying the adhesive to the adhesive inlet, the heated fluid is transported through the input pipe to the space between the outer and inner jackets, and then to the output pipe. The heat of the fluid is transferred to the spray lip inside the inner jacket, and then to the adhesive passing through the spray lip, heating and maintaining the temperature of the adhesive. The adhesive is then output to the cooling equipment through the output slot on the support plate, becoming a biomass film. During operation, the temperature of the biomass film can be well maintained, preventing the raw materials for biomass film production from condensing. Preheating can be performed inside the equipment, reducing waiting time for production and reducing material waste.

[0015] This invention solves the problem of inaccurate pressure and temperature monitoring of adhesive flow in biomass film production equipment by setting up a support plate, outer jacket, and insulation pipe. Before operation, a probe for detecting adhesive pressure is inserted into one insulation pipe, and a probe for detecting adhesive temperature is inserted into another insulation pipe. The installation structure is placed on the mounting plate and installed using screws and other means. The probes and other structures are then installed on the insulation pipes, and the top of the insulation pipes is sealed. This allows for convenient monitoring of adhesive temperature and pressure during operation, making it easier to monitor the pressure and temperature of adhesive flow in biomass film production equipment.
