Description

Technical Field

[0001] The present application relates to the field of biomass solid fuel preparation, and in particular, to a biomass rod forming machine. Background Art

[0002] The biomass rod forming machine is mainly composed of components such as a transmission mechanism, a feed pipe, a forming sleeve and a heating mechanism. The existing technology is to put the crushed biomass into the feed port on the biomass rod compressor, and the biomass is decomposed by heat after passing through the machine heating device, and the heated biomass raw material is processed into a rod shape, thereby realizing the processing of biomass rods.

[0003] However, the biomass bar making machines on the market use coil heating, which causes uneven heating of the biomass in the pipeline, resulting in unstable product quality. Secondly, coil heating requires electricity, which limits the space for the machine and makes it inconvenient to use the machine in areas without electricity at the raw material site. In addition, since the commercially available machines have only a single compression ratio and can only produce a single product, the biomass bar forming machine with an unvariable compression ratio has some disadvantages. When processing biomass raw materials of different types and characteristics, the compression ratio cannot be flexibly adjusted to achieve the best forming effect. This may lead to problems such as difficulty in forming and unstable quality when processing certain biomass raw materials. In the case of an unvariable compression ratio, it is difficult for the forming machine to flexibly control the calorific value and shape of the product, so product quality control may be limited. Since the compression ratio cannot be adjusted as needed, the forming machine may not be able to achieve the best production efficiency under different production requirements, thereby affecting output and production efficiency. These shortcomings may limit the flexibility and adaptability of the equipment, affecting production efficiency and product quality. It is difficult to adapt to diversified market demands. Utility Model Content

[0004] In order to make up for the above shortcomings, the present application provides a biomass rod forming machine to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model to solve its technical problems is:

[0006] A biomass rod forming machine comprises a hydraulic cylinder, characterized in that: the hydraulic cylinder is connected to a piston through a push rod, the outer wall of the piston is provided with a rod output pipe, the outer wall of the rod output pipe is surrounded and fixed with a heat-conducting oil cylinder, a silo is welded on one end of the surface, a forming cavity exhaust seam is opened at the other end, and a forming cavity mold is installed, the interior of the rod output pipe is communicated with the interior of the silo, and a biomass combustion furnace is installed below the heat-conducting oil cylinder.

[0007] Furthermore, the piston push end is provided with a piston force component head, and the outer wall of the piston force component head is tightly fitted with the inner wall of the rod output tube.

[0008] Furthermore, the thermal oil cylinder includes a thermal oil cylinder insulation layer, a thermal oil cylinder exhaust condenser and a thermometer. The outside of the thermal oil cylinder is surrounded by the thermal oil cylinder insulation layer, and the thermal oil cylinder exhaust condenser is welded at one end above, and the thermometer is installed at the other end. The interior of the thermal oil cylinder exhaust condenser is interconnected with the interior of the thermal oil cylinder.

[0009] Furthermore, the molding cavity mold includes two groups of adjusting screws and two groups of upper and lower plates. Two upper and lower plates are respectively provided at opposite ends of the two groups of adjusting screws and are installed at the discharge end of the bar output pipe.

[0010] Furthermore, the biomass combustion furnace includes a feed inlet, a direct air inlet, a direct ventilation port, a secondary air inlet, an air heating chamber and a secondary ventilation port. The feed inlet is provided on the outer wall of the biomass combustion furnace, and the feed inlet is connected to the inside of the biomass combustion furnace. The direct air inlet is provided on the bottom of the side of the biomass combustion furnace, and the direct ventilation port is provided on the inner bottom, and the two ports are interconnected. The secondary air inlet is provided on the side wall of the biomass combustion furnace, and the outside is set as the air heating chamber, and the secondary ventilation port is provided on the top of the air heating chamber.

[0011] Furthermore, the top of the biomass combustion furnace is fixedly connected to the bottom of the heat-conducting oil cylinder and horizontally supports the rod output pipe.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model aims at the problem of uneven heating of coil heating (electric heating), improves the use of heat-conducting oil cylinder for indirect heating, abandons the use of high-energy consumption and low-efficiency methods such as electric heating and friction heating, and completes the uniform heating of biomass raw materials.

[0014] 2. The utility model aims at the heating method problem, improves the use of biomass waste from the production site and biomass rods after production as fuel, and uses a biomass combustion furnace to heat the heat transfer oil cylinder, thereby achieving high-temperature bonding of biomass raw materials. The advantage of this improvement is that it does not require the use of electricity, and production can be carried out in raw material sites without electricity, thus fully saving energy.

[0015] 3. The utility model improves the primary heating mode on the market and uses a secondary heating mode. The design of adding a secondary air inlet, an air heating chamber and a secondary vent below the biomass combustion furnace achieves efficient combustion of biomass and effective utilization of heat energy. The high-temperature exhaust gas enters the secondary air inlet and carries part of the oxygen, making the fuel burn more evenly, with the dual advantages of environmental protection and energy saving.

[0016] 4. The utility model solves the problem that the rod making machines on the market cannot flexibly adjust the compression ratio. The improved machine adjusts the tightness of the screws on the molding cavity mold to control the distance between the upper and lower plates of the molding cavity mold, thereby changing the compression ratio. The machine with a variable compression ratio can complete the solidification and molding of various biomass waste materials and produce biomass rods with different calorific values.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0023] Example:

[0024] See also Figure 1 , Figure 2 , Figure 3 A biomass bar forming machine includes a hydraulic cylinder 1, which serves as a hydraulic system of a forming tool and can continuously push the biomass entering the bar output pipe 3 from the silo 5 into a heating area. The pressure strength and speed can also be precisely controlled by adjusting the flow and pressure of the hydraulic oil.

[0025] See also Figure 1 , Figure 2 , a biomass rod forming machine, a hydraulic cylinder 1 is connected to a piston 2 through a push rod, a rod output pipe 3 is provided on the outer wall of the piston 2, a heat-conducting oil cylinder 4 is fixed around the outer wall of the rod output pipe 3, and a silo 5 is welded on one end of the surface, a molding cavity exhaust seam 6 is opened on the other end, and a molding cavity mold 7 is installed, the inside of the rod output pipe 3 is communicated with the inside of the silo 5, and a biomass combustion furnace 8 is installed below the heat-conducting oil cylinder 4; the piston 2 push end is equipped with a piston force component 21; the heat-conducting oil cylinder 4 includes a heat-conducting oil cylinder insulation layer 41, a heat-conducting oil cylinder exhaust condenser 42 and a thermometer 43; the molding cavity mold 7 includes two sets of adjusting screws 71 and two sets of upper and lower plates 72; the biomass combustion furnace 8 includes a feed inlet 81, a direct air inlet 82, a direct vent 83, a secondary air inlet 84, an air heating cavity 85 and a secondary vent 86.

[0026] Among them, the rod output pipe 3 is designed to transport biomass materials, which is convenient for the hydraulic cylinder 1 to act on the piston 2 to ensure that the material can be continuously and stably supplied to the molding area; at the same time, it is convenient to install the heat-conducting oil cylinder 4 on the surface to form a heating area inside it.

[0027] Among them, the heat-conducting oil cylinder 4 is used as a heating device, which can transfer heat energy to the biomass rods evenly, avoiding overheating or overcooling of some rods, and ensuring the stability of the molding quality. The heat-conducting oil cylinder 4 as a heating device can effectively improve the heating efficiency and molding quality of the biomass rod molding machine, and reduce energy consumption and costs.

[0028] Among them, in order to prevent the material from arching, clogging, sticking to the wall, and being retained in the silo 5, the two ends of the stirring blade used to stir the biomass inside the silo 5 can be designed to be one high and one low, which plays the role of breaking the arch and allows the biomass to slide normally. The piston 3 is then used to push the biomass into the heating area. The heating area uses the heat-conducting oil cylinder 4 to transfer heat so that the biomass is heated evenly during the heating process. A heat-conducting oil cylinder insulation layer 41 is set on the outside of the heat-conducting oil cylinder 4 to prevent the heat of the heat-conducting oil cylinder 4 from being lost. In order to facilitate the adjustment of the temperature of the heat-conducting oil, the heat-conducting oil cylinder exhaust condenser 42 is used to adjust the temperature, and at the same time, the function of adjusting the compression ratio is achieved to produce biomass rods with different calorific values. A thermometer 43 is set above the heat-conducting oil cylinder 4 to observe the temperature change. During production, workers can use the heat-conducting oil cylinder exhaust condenser 42 and the thermometer 43 to adjust the required temperature in time.

[0029] Among them, a molding cavity exhaust slit 6 is designed at one end of the rod output pipe 3, so that the heat generated by the biomass rod after heating can be discharged through the molding cavity exhaust slit 6.

[0030] Among them, the machine adopts an adjustable compression ratio design, so that the operator can freely adjust the pressure as needed. By increasing or decreasing the pressure, the compression degree of the biomass waste during the molding process can be controlled, so as to achieve the production of biomass rods with different calorific value requirements. The molding cavity mold 7 is a device for adjusting the pressure. When the screws on the molding cavity mold 7 are in a loose state, the opening of the molding cavity mold 7 will become larger, and the molded product will also become larger accordingly. On the contrary, when the screws are in a tighter state, the opening of the molding cavity mold 7 will become smaller, and the molded product will also become smaller accordingly. Therefore, by properly adjusting the tightness of the screws, the size of the molded product can be controlled. Adjusting the tightness of the screws can also be used to adjust the closing force of the molding cavity mold 7 to ensure the calorific value and shape stability of the molded product.

[0031] Among them, the outer wall of the biomass combustion furnace 8 is provided with a feed port 81 for adding biomass fuel into the furnace, using the finished product as fuel to realize the "self-heating" function. The feed port 81 is connected to the inside of the biomass combustion furnace 8 to ensure that the fuel can smoothly enter the combustion area. A direct air inlet 82 is provided at the side bottom of the biomass combustion furnace 8 to introduce fresh air into the furnace to promote the initial combustion of the fuel. The direct vent 83 is located at the bottom of the furnace and is connected to the direct air inlet 82 to ensure the uniform distribution and effective circulation of fresh air. A secondary air inlet 84 is provided on the side wall of the biomass combustion furnace 8 to introduce secondary air during the combustion process to enhance the combustion effect of the fuel. The external air heating chamber 85 surrounds the secondary air inlet 84 to preheat the secondary air entering the furnace, increase the combustion temperature, and promote the full combustion of the fuel. A secondary air inlet 84 is provided on the side wall of the biomass combustion furnace 8 to introduce secondary air during the combustion process to enhance the combustion effect of the fuel. The external air heating chamber 85 surrounds the secondary air inlet 84 and is used to preheat the secondary air entering the furnace, increase the combustion temperature, and promote the full combustion of the fuel. A secondary vent 86 is provided at the top of the air heating chamber 85 to introduce the preheated secondary air into the furnace. The design of the secondary vent 86 can ensure the effective mixing of the preheated air and the combustion area, thereby improving the combustion efficiency.

[0032] The working principle of the biomass rod forming machine is as follows: the crushed biomass raw material is put into the silo 5, and the raw material will enter the rod output pipe 3 along the middle opening of the silo 5, the gas in the hydraulic cylinder 1 expands to push the piston 2, and the piston 2 pushes the piston force head 21 to move, and then the raw material is pushed by the piston 2 in the rod output pipe 3 to the heating part of the heat-conducting oil cylinder 4 for heating. The fuel enters the biomass combustion furnace 8 from the feed inlet 81. The direct vent 83, the secondary air inlet 84, and the secondary vent 86 are vents, and the oxygen in the air enters the biomass combustion furnace 8 through the direct vent 83, the secondary air inlet 84, and the secondary vent 86 vents to allow the fuel to burn fully. In order to avoid incomplete combustion of the material in the first combustion, the secondary vent 86 is designed to ensure that the second combustion is complete and avoid the generation of harmful and polluting gases. The heated air gathers in the heat-conducting oil cylinder 4 to heat the heat-conducting oil in the cylinder. During the heating process, the temperature of the heating chamber can be observed by the thermometer 43, and the heat-conducting oil cylinder exhaust condenser 42 can adjust the temperature in the heat-conducting oil cylinder 4, so that the staff can adjust the product as required. The heat generated by the biomass bar after heating can be discharged through the molding cavity exhaust slit 6. Finally, the screws on the molding cavity mold 7 are adjusted to control the width between the upper and lower plates 72, and the product is delivered after the required biomass size is obtained.

[0033] It should be noted that the specific model and specifications of the hydraulic cylinder 1 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
