Technical Field

[0001] The utility model relates to the technical field of biomass waste crushing, in particular to a biomass particle waste crushing device. Background Art

[0002] Biomass fuel is a block-shaped environmentally friendly new energy source produced by processing straw, rice straw, rice husks, peanut shells, corn cobs, oil tea shells, cottonseed shells, etc. as well as "three wastes". Biomass pellets are an important component of biomass fuel. The diameter of biomass pellets is generally 6~10 mm. Biomass waste is generally raw materials produced after processes such as crushing, pulverizing, drying, and iron removal. The raw materials are then granulated to make the final product.

[0030] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in a variety of different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 5 As shown, the utility model includes a shell 1, in which two counter-rotating crushing rollers 2 are installed for crushing biomass waste, each crushing roller 2 is installed with crushing teeth 201 and crushing knives 202, and a vibration block 3 is provided above the crushing roller 2, and the vibration block 3 is fixed on the left and right sides of the shell 1, and a baffle plate 502 is installed below the crushing roller 2, and two guide wheels 4 are provided above the baffle plate 502. Dryers 5 are provided on both sides of the two guide wheels 4 for pre-drying the material for the first time to prepare for the subsequent formal drying process, and discharge ports 503 are provided at the left and right ends of the baffle plate 502. A wedge-shaped electromagnetic block 6 is installed below each discharge port 503, which can absorb metal impurities in the material when energized;

[0033] The lower portion of the shell 1 is connected to a discharge hopper 7 which serves as a discharge channel for the finished product.

[0034] An upper fixed plate 101 is installed on the front end surface of the outer side of the shell 1 and two bearing seats 1012 are provided on the fixed plate 101. A machine box a102 is installed on the rear end surface of the outer side of the shell 1. The center of the two crushing rollers 2 is the roller shaft 203. The front end of the roller shaft 203 passes through the shell 1 and is fixed in the bearing seat 1012. The rear end passes through the rear end surface of the shell 1 and is connected to the drive motor in the machine box a102 through a conveyor belt 204, which is used to drive the two crushing rollers 2 to rotate; the rear end of the roller shaft 203 is also fixed by the bearing seat 1012, and the bearing seat 1012 at the rear end is set in the shell 1.

[0035] The surfaces of the two vibration blocks 3 that are close to each other are wedge-shaped, which is conducive to the sliding of materials. They are the feeding point of materials. Each vibration block 3 is provided with a cavity inside and several vibration motors 301 are installed in the cavity. On the one hand, it is convenient for unloading materials. On the other hand, it makes the materials that are being crushed but not yet broken (such as straw, etc.) vibrate to improve the crushing efficiency. A rubber block 302 is fixed at the position where the lower end surface of the vibration block 3 contacts the shell 1 to reduce the vibration of the vibration motor 301 on the whole machine.

[0036] The crushing teeth 201 and the crushing knives 202 are both circumferentially and axially staggeredly installed on the crushing roller 2. The function of the crushing teeth 201 is to cut the material up and down when rotating, and on the other hand, "grasp" the material and drive it to sink. The function of the crushing knife 302 is to separate the material front and back. The sharp edge direction of the crushing knife 202 is opposite to that of the crushing teeth 201, which helps to crush. The crushing knife 202 is located between the front and rear crushing teeth 201 on the circumference.

[0037] The two guide wheels 4 are controlled to rotate by the motor in the chassis b401. The guide wheels 4 are both equipped with strip-shaped material-moving rods 402, and the material-moving rods 402 of the two do not contact each other during rotation. The materials falling from between the crushing rollers 2 are moved to the discharge port 503 by the material-moving rods 402. During this period, the materials are pushed through the dryer 5 for heating and initial drying.

[0038] There are four discharge ports 503, two of which are arranged on each side; drying channels 501 are arranged on the left and right ends of the outer side of the shell 1, one end of the drying channel 501 passes through the shell 1 and is connected to the dryer 1, and the other end is connected to the dryer on the outside. The hot air generated by the dryer 5 needs to be provided by the dryer through the drying channel 501.

[0039] Four supporting feet 601 are provided on the four corners of the side of the housing 1 and a rubber pad 801 is provided at the bottom of each supporting foot 601 to reduce external vibration.

[0040] Each electromagnetic block 6 is in the shape of a wedge pointing downward toward the center, and the inclined surface of each electromagnetic block 6 is set to be serrated. When energized, it can adsorb metal impurities such as nails in the material. The serrated design will cause the metal impurities to be stuck in the serrated groove after adsorption and will not fall off easily.

[0041] This device is powered by the socket 601 on the outside of the shell 1. Both chassis a102 and chassis b401 have built-in conventional electrical control components such as PLC controllers and encoders. The connection and control methods of each electrical component are well known to people in this field and will not be repeated here.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
