[0002] In the furfural production process, its raw material is corn cobs. The remaining corn cob waste after production processing can still be used as the raw material of biomass fuel. After being pressed and extruded into granules and then dried, it can be used as fuel for biomass boilers and industrial furnaces. Biomass pellets are currently relatively economical environmentally friendly materials, and their emission standards meet the requirements of GB13271-2004 "Boiler Air Pollutant Emission Standards". In the prior art, the processing equipment of biomass pellets usually uses a motor to drive a mechanical wheel after being decelerated by a reducer. During the rotation of the wheel, the biomass raw materials are rolled into shape, which consumes a lot of electricity. Each ton of biomass pellets requires 130 degrees of electricity. The mold has a short service life. When it is fully loaded, a set of molds needs to be replaced every two months. The use cost is high, the structure is complex, the volume is large, and the equipment is expensive. Therefore, in view of the above shortcomings, a hydraulic biomass pellet machine is proposed.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1 As shown, the utility model provides a hydraulic biomass pellet machine, comprising:

[0022] The compression cylinder 3 and the bracket 8 are provided. The compression cylinder 3 is used as a container for compressing raw materials. The raw materials are formed after being squeezed by the compression device in the compression cylinder 3. The compression cylinder 3 is provided with a movable compression body 2. During operation, the movable compression body 2 moves up and down along the compression cylinder 3 in the compression cylinder 3 to squeeze the raw materials in the compression cylinder 3. The diameter of the movable compression body 2 matches the inner diameter of the compression cylinder 3, which prevents the raw materials from escaping from the gap between the movable compression body 2 and the compression cylinder 3 while ensuring the normal operation of the device, thereby reducing the waste of raw materials and improving the practical efficiency of the device.

[0023] A guide rod 5 is provided at the tail of the movable compression body 2 , and the guide rod 5 extends out of the compression cylinder 3 . The movable compression body 2 can move up and down in the compression cylinder 3 by pushing and pulling the guide rod 5 .

[0024] It should be noted that the outlet end of the compression cylinder 3 is installed obliquely downward during the installation process, so that the raw materials in the compression cylinder 3 are concentrated near the outlet, which provides convenience for the subsequent compression work. At the same time, the oblique downward installation method makes the unloading process of the device smoother and improves the working efficiency of the device.

[0025] In the present invention, a hydraulic cylinder 7 is respectively provided on both sides of the compression cylinder 3, and the two hydraulic cylinders 7 are symmetrically arranged. A pressure arm 6 is provided at the movable end of each hydraulic cylinder 7, and one end of the pressure arm 6 is connected to the movable end of the hydraulic cylinder 7 and the other end is connected to the guide rod 5. When the hydraulic cylinder 7 performs piston movement, the pressure arm 6 transmits the force of the hydraulic cylinder 7 to the guide rod 5, thereby driving the guide rod 5 to move up and down in the compression cylinder 3.

[0026] Among them, a guide rail is provided in the compression cylinder 3, and the guide rod 5 passes through the guide rail to control the movement direction of the guide rod 5, to prevent the guide rod 5 from deviating in direction during the operation of the device, causing device failure or even damage, and to improve the safety of the device.

[0027] like Figure 1 As shown, a raw material bin 1 is provided above the compression cylinder 3, and the lower part of the upper opening of the raw material bin 1 is connected to the compression cylinder 3 and the connection point is close to the outlet of the compression cylinder 3. During use, raw materials are added to the opening above the raw material bin 1. When the hydraulic cylinder 7 contracts, the movable end of the hydraulic cylinder 7 drives the guide rod 5 to move upward through the pressure arm 6. At this time, the movable compression body 2 moves upward with the pressure arm 6, and the interface between the raw material bin 1 and the compression cylinder 3 is opened. The raw materials in the raw material bin 1 fall into the compression cylinder 3 under the action of gravity, and then the hydraulic cylinder 7 extends, and the pressure arm 6 moves with the movable end of the hydraulic cylinder 7, driving the guide rod 5 to move downward. At this time, the movable compression body 2 moves downward with the guide rod 5 to squeeze the raw materials in the compression cylinder 3, and the cycle is repeated.

[0028] Among them, a mold 4 is provided at the outlet of the compression cylinder 3, and the mold 4 is processed into a corresponding shape according to production needs. During the operation of the device, the raw materials in the compression cylinder 3 are compressed in volume under the extrusion of the movable compression body 2 and move toward the outlet of the compression cylinder 3. The mold 4 restricts the raw materials so that the finished product extruded from the mold 4 is in the shape required for production. After being pressed out of the mold 4, the finished product falls off automatically when it reaches a certain volume due to its own gravity, and no manual demolding is required, and the working process is simple.

[0029] Furthermore, a fulcrum is provided at a position corresponding to the middle part of each of the pressure arms 6, and the pressure arm 6 cooperates with the fulcrum to form a lever structure. At this time, when the compression cylinder 3 is extended, the pressure arm 6 is pushed forward, and the guide rod 5 is lifted up by the lever structure to move the movable compression body 2 upward. When the compression cylinder 3 is contracted, the pressure arm 6 is pulled backward, and the guide rod 5 is pressed down by the lever structure to move the movable compression body 2 downward, thereby squeezing the raw materials in the compression cylinder 3. The lever structure can adjust the length of the force arm on both sides of the lever by adjusting the fulcrum position, so that the device is more labor-saving during use, reduces the resistance of the hydraulic cylinder 7 during operation, improves the working efficiency of the device, and at the same time extends the service life of the device and reduces the equipment cost.

[0030] The mold 4 and the compression cylinder 3 are detachably connected. When the mold 4 is damaged, only the mold 4 needs to be replaced to restore normal operation, thereby improving the economy of the device. At the same time, when the production plan of the device changes, only the mold 4 of different models and shapes needs to be replaced to process different products, thereby improving the applicability of the device.

[0031] In the present invention, the compression cylinder 3 and the hydraulic cylinder 7 are both mounted on a bracket 8, and the bracket 8 serves to fix and protect surrounding components. An outer guide rail is provided at a position on the bracket 8 corresponding to the guide rod 5. The outer guide rail cooperates with the guide rail in the compression cylinder 3 on the same straight line, further limiting the movement trajectory of the guide rod 5 and the movable compression body 2 connected to the guide rod 5, thereby ensuring the normal operation of the device to the greatest extent.

[0032] Among them, the bracket 8 is in the shape of a right triangle, the compression cylinder 3 is installed on the angle bisector of the right triangle, and the two hydraulic cylinders 7 are installed on two right-angled sides respectively. The triangular structure makes the device more stable as a whole, and at the same time facilitates the alignment of the compression cylinder 3 during installation or replacement, thereby improving the work efficiency during maintenance and reducing the work intensity and working time during device maintenance.

[0033] Combination Figure 1 The following is a detailed description of the working steps of this hydraulic biomass pellet machine:

[0034] First, start the device. At this time, the two hydraulic cylinders perform periodic reciprocating motion under the drive of the motor. At the same time, the pressure arm transmits the power of the hydraulic cylinder to the guide rod, thereby driving the movable compression body to perform uninterrupted up and down motion in the compression cylinder.

[0035] Then, add materials into the raw material bin. At this time, under the action of gravity, the materials in the raw material bin fall into the compression cylinder when the movable compression body moves upward. When the movable compression body moves downward, the raw materials in the compression cylinder are pressurized and compressed. The compressed raw materials are shaped by the mold and extruded from the outlet of the compression cylinder.

[0036] Finally, the finished product extruded from the compression cylinder outlet is separated from the die and falls under the action of its own gravity, and the fallen finished product particles are collected at the compression cylinder outlet.

[0037] Generally speaking, commonly used biomass pellet machines mostly use discs as compression components, which are bulky, consume a lot of electricity, and exert a lot of pressure on the mold during use. When the biomass pellet machine described in the embodiment is used, the hydraulic cylinder as a compression component occupies a small area and has low energy consumption, and only requires a relatively small space to work.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
