Description

Technical Field

[0001] The present invention relates to the technical field of biomass energy processing equipment, and in particular to an intelligent integrated processing equipment for biomass particles. Background Art

[0002] With the intensification of the global energy crisis and the increasing severity of environmental problems, the search for clean and renewable energy has become an important issue in today's world. As a renewable energy source, biomass energy has the advantages of wide sources, abundant reserves, and environmental protection, and has received more and more attention. Biomass pellets are an important form of biomass energy. It is a solid fuel made by crushing, drying, and molding biomass raw materials.

[0003] At present, the processing equipment of biomass pellets mainly has the following problems:

[0004] First, because the powder has a small specific gravity and is dry, dust will fly during the transportation process of the material, such as when the loader pushes and pours it, and when the conveyor belt falls down, the visibility in the workshop is almost very low, and the working environment is very poor, which has a great impact on people;

[0005] Secondly, during the operation of the pellet machine, the gap between the roller and the die will increase due to wear, which will reduce the output and increase the motor current, or even stop production. The power consumption will increase, often resulting in motor choking, increased production costs, and even equipment damage. Existing pellet machines require frequent manual gap adjustment. Due to different technical capabilities of people, improper adjustment often leads to problems such as misalignment, which often leads to low production capacity and equipment damage.

[0006] Finally, during the operation of the equipment, one person is needed to guard the electrical cabinet, frequently adjust the feed speed, and control the operating current. Failure to supervise will lead to excessive current choking the main motor, burning the motor, damaging the reducer, and other faults.

[0007] Therefore, there is an urgent need for a biomass particle processing equipment that can protect the working environment and can automatically control and adjust. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figure 1-2 As shown, an intelligent integrated processing equipment for biomass pellets includes a wood powder collecting vehicle, a first-stage feeder 9, a drum screen 10, a second-stage feeder 12, a pellet machine 13, and a PLC controller 17. The wood powder collecting vehicle is connected to the drum screen 10 through the first-stage feeder 9, and the drum screen 10 is connected to the pellet machine 13 through the second-stage feeder 12;

[0034] The wood powder collecting vehicle comprises a frame 1, the frame 1 is connected to a propulsion wheel 2, the propulsion wheel 2 is transmission-connected to a propulsion wheel driver 3, the propulsion wheel 2 is connected to a thrust sensor 4, the frame 1 is connected to a scraper driver 7, the scraper driver 7 is connected to a rotary scraper 8, the frame 1 is connected to a wood powder conveyor 5, the feed port of the wood powder conveyor 5 corresponds to the rotary scraper 8, and the discharge port of the wood powder conveyor 5 is connected to the feed port of a first-stage feeder 9;

[0035] The discharge port of the first-stage feeder 9 is connected to the feed port of the drum screen 10, and the discharge port of the drum screen 10 is connected to the feed port of the second-stage feeder 12. A weighing sensor 11 is connected to the bottom of the drum screen 10;

[0036] The discharge port of the second-stage feeder 12 is connected to the feed port of the pellet machine 13. The pellet machine 13 is provided with a hydraulic cylinder 15 and a displacement sensor 16. The hydraulic cylinder 15 is connected to the body frame of the pellet machine 13. The push end of the hydraulic cylinder 15 is connected to the pressure roller bracket of the pellet machine 13. The hydraulic cylinder 15 is connected to the hydraulic cylinder control device 14. The displacement sensor 16 is connected to the pressure roller bracket of the pellet machine 13.

[0037] The propulsion wheel driver 3, the thrust sensor 4, the wood powder conveyor 5, the scraper driver 7, the first-stage feeder 9, the drum screen 10, the weighing sensor 11, the second-stage feeder 12, the pellet machine 13, the hydraulic cylinder control device 14, and the displacement sensor 16 are respectively connected to the PLC controller 17.

[0038] How it works

[0039] Each electrical device and electrical components are controlled by a PLC controller 17. First, the wood powder collecting vehicle collects the powder on the ground and transports it to the drum screen through the first-stage feeder 9. The screened powder is then transported to the pellet machine 13 by the second-stage feeder 12 to form biomass pellets.

[0040] When the wood powder collecting vehicle starts working, the propulsion wheel driver 3 drives the propulsion wheel 2 forward or backward, so that the rotary scraper 8 is close to the material to be collected. The scraper driver 7 is started, driving the rotary scraper 8 to move, and the rotary scraper 8 rotates around the central axis. During the rotation process, the edge of the scraper is used to pick up the material and throw it to the wood powder conveyor 5. The wood powder conveyor 5 conveys the material collected by the scraper to the first-level feeder 9.

[0041] The propulsion wheel 2 is connected to a thrust sensor 4, which is connected to a PLC controller 17. The PLC controller 17 controls the normal operation of the wood powder collecting vehicle. If there is too much powder, the thrust sensor 4 outputs a signal, and the PLC controller 17 controls the propulsion wheel driver 3 to stop forward rotation. After the powder is collected and transported to the drum screen 10, the powder in front of the wood powder collecting vehicle decreases, and the thrust sensor 4 outputs a signal again, and the PLC controller 17 controls the propulsion wheel driver 3 to start forward rotation, so that the wood powder collecting vehicle can continuously provide materials to the equipment when production needs materials.

[0042] The legs of the drum screen 10 are connected with a weighing sensor 11, which is connected to a PLC controller 17. When the weighing sensor 11 detects that the weight of the material in the drum screen 10 reaches a lower set value or the screen is empty, the PLC controller 17 controls the wood powder collecting vehicle to run and convey the collected material to the drum screen 10. When the weighing sensor 11 detects that the weight of the material in the drum screen 10 reaches an upper set value, the PLC controller 17 controls the wood powder collecting vehicle to stop working, thereby ensuring that the material under the drum screen 10 is continuously supplied during the production of pellets.

[0043] The gap adjustment of the pellet machine 13 is automatically adjusted by the hydraulic cylinder 15. According to the signal transmitted by the displacement sensor 16 to the PLC controller 17, the equipment automatically adjusts during operation without problems such as adjustment deviation and uneven gaps between the rollers. The production is stable and equipment failures are reduced. In addition, the wear status of the roller mold can be monitored in real time, and the roller gap can be adjusted as needed when drying special materials.

[0044] The hydraulic cylinder 15 is fixed on the body frame of the pellet machine 13, and the push end is connected to the pressure roller bracket of the pellet machine 13. The hydraulic cylinder 15 is connected to the hydraulic cylinder control device 14 for supplying liquid, and the hydraulic cylinder control device 14 is connected to the PLC controller 17. According to the actual gap information fed back by the displacement sensor 16, the PLC controller 17 controls the hydraulic cylinder 15 to extend and retract through the hydraulic cylinder control device 14. When the hydraulic cylinder 15 extends outward, the gap between the pressure rollers is reduced, and when the hydraulic cylinder 15 retracts inward, the gap between the pressure rollers is increased.

[0045] A displacement sensor 16 is installed at the pressure roller of the pellet machine 13, and the displacement sensor 16 directly measures the gap size between the pressure roller and the ring die. The displacement sensor 16 transmits the measured gap data to the PLC controller 17 in real time, and the PLC controller 17 compares these data with the preset standard gap value. If the actual gap does not meet the requirements, the PLC controller 17 will automatically issue an instruction to start the hydraulic cylinder control device 14 to adjust the gap through the hydraulic cylinder 15 until the actual gap reaches the preset value. This automatic feedback and adjustment mechanism can ensure that the pellet machine 13 always maintains the best gap state during operation, thereby improving the molding quality and production efficiency of the pellets.

[0046] The current signal output interface of the motor of the pellet machine 13 is connected to the PLC controller 17. The working current is set according to the power of the pellet machine 13. The PLC controller 17 controls the feeding speed. If the current is slightly larger, the feeding speed is reduced, and if the current is slightly lower, the feeding speed is increased, so that the working current is stably controlled and there will be no faults such as the motor being held back and burned, or the reducer gear being damaged.

The resistance strain sensor has an accuracy of 0.10%, and can be applied to fields such as push-pull force gauges, automated force measurement, and assembly pressure testing, and can effectively improve the working efficiency and working effect of the thrust sensor 4.

[0055] The wood powder conveyor 5, the first-stage feeder 9, and the second-stage feeder 12 are all belt conveyors. The belt conveyor has a good transmission function and can effectively improve the working efficiency and working effect of the wood powder conveyor 5, the first-stage feeder 9, and the second-stage feeder 12.

[0056] The current signal output interface of the motor of the pellet machine 13 is connected to the PLC controller 17. This wiring is relatively simple and does not require additional current conversion equipment; the resources of the PLC controller 17 can be directly used for current monitoring and data processing, reducing the cost and complexity of the system.
