DETAILED DESCRIPTION

[0019] The utility model is further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and not limiting of the protection scope of the utility model.

[0020] Example

[0021] like Figure 1-Figure 4 As shown: An automatic loading and unloading biomass combustion equipment, comprising: a combustion chamber 1 is the core part of the equipment, one side of which is provided with a feeding conveyor belt 2 for conveying the material to be burned into the combustion chamber. The other side of the combustion chamber 1 is provided with a discharging conveyor belt 3 for discharging the waste or ash and other materials after burning from the combustion chamber.

[0022] In order to protect the combustion chamber 1 and improve safety, a shell 4 is provided outside the combustion chamber 1. A blower 5 is installed on one side of the shell 4 to provide airflow to the combustion chamber 1 to make the combustion more complete and stable.

[0023] A porous carrying plate 6 for carrying articles is provided inside the combustion chamber 1. The porous carrying plate 6 has certain strength and air permeability, and can carry the materials to be burned and allow the waste ash to pass through.

[0024] In order to keep the inside of the combustion chamber 1 clean, a cleaning assembly 7 is provided below the porous carrier plate 6. The cleaning assembly 7 can remove the residues on the porous carrier plate and guide them to the bottom.

[0025] When the waste or ash falls from the bottom of the cleaning assembly 7, it encounters an inclined plate 8, which is located above the discharge conveyor belt 3. The function of the inclined plate 8 is to guide the waste into the discharge conveyor belt 3 to ensure that the waste is discharged from the equipment smoothly.

[0026] The above scheme can realize convenient material input and waste discharge, while keeping the combustion chamber clean and improving combustion efficiency and safety.

[0027] It can be understood that: the position of the combustion chamber 1 near the feed conveyor belt 2 is provided with a feed trough 101. The feed trough 101 is located between the combustion chamber 1 and the feed conveyor belt 2, and plays a role in connecting the two.

[0028] Inside the feed trough 101, there is a rotatable connecting device, which is used to prevent the fire source airflow from flowing back into the feed conveyor belt 2. This connecting device is called a feed sealing plate 102.

[0029] The feed sealing plate 102 has a rotatable structure, which can be tightly connected with the feed trough 101 and can rotate freely. When the feed conveyor belt 2 is running, the feed sealing plate 102 will rotate with the movement of the conveyor belt.

[0030] By being tightly connected to the feed trough 101 and being designed to rotate, the feed sealing plate 102 can effectively prevent the fire source airflow from flowing back into the feed conveyor belt 2. This can prevent the fire source or smoke in the combustion chamber 1 from flowing back into the feed conveyor belt 2, thereby protecting the conveyor belt and preventing the occurrence of potentially dangerous situations.

[0031] The presence of the feed sealing plate 102 ensures the safe separation between the combustion chamber 1 and the feed conveyor belt 2, reducing the occurrence of fire and other safety risks. This provides a guarantee for the normal operation of the combustion equipment and protects the safety of operators and equipment.

[0032] It can be understood that: a discharge trough 103 is provided on one side of the combustion chamber 1 close to the discharge conveyor belt 3. The discharge trough 103 is located between the combustion chamber 1 and the discharge conveyor belt 3, and serves to connect the two.

[0033] A second discharge trough 104 for larger impurities to flow through is provided at the top of the discharge trough 103. The second discharge trough 104 is located inside the discharge trough 103 and is connected thereto through a connecting pipe or channel.

[0034] The inner wall of the second discharge chute 104 is fixedly connected to the second sealing plate 105. The second sealing plate 105 is installed on the inner wall surface of the second discharge chute 104 to ensure sealing during the discharge process.

[0035] When waste or ash falls from the combustion chamber 1 to the discharge chute 103, larger impurities will enter the second discharge chute 104. The design of the second discharge chute 104 allows larger impurities to flow therein, avoiding blockage or obstruction of the smooth discharge of materials.

[0036] The second sealing plate 105 is fixedly connected to the inner wall of the second discharging trough 104 to ensure that the waste material will not overflow or leak out during the circulation process. This sealing design can prevent the waste material from contaminating or damaging the discharging conveyor belt 3 or other equipment.

[0037] Through the structure and connection of the discharge chute 103, the second discharge chute 104 and the second sealing plate 105, smooth material flow and effective sealing control are achieved between the combustion chamber 1 and the discharge conveyor belt 3. This can ensure efficient discharge of waste or ash and maximize the operating efficiency and safety of the equipment.

[0038] It is understandable that the porous carrier plate 6 is provided with a sliding groove 601 for sliding the cleaning component 7. The sliding groove 601 is located on the porous carrier plate 6 and is used to accommodate the cleaning component 7 so that it can slide on the porous carrier plate when needed.

[0039] The design of the sliding groove 601 allows the cleaning assembly 7 to slide freely on the porous carrier plate 6 and can be adjusted in position as required, so that the porous carrier plate 6 can be easily cleaned or maintained to keep it in normal working condition.

[0040] On both sides of the sliding groove 601, there are connecting holes 602 for handling impurities when they fall into the inclined plate 8. When impurities slide down from the porous supporting plate 6 and enter the sliding groove 601, the connecting holes 602 can guide the impurities to the inclined plate 8.

[0041] The function of the connecting hole 602 is to connect the sliding groove 601 with the inclined plate 8 to achieve smooth transfer of impurities. The inclined plate 8 is usually located below the sliding groove 601, and the inclined angle can make the impurities slide along the surface of the inclined plate for easy collection or discharge.

[0042] The existence of the sliding groove 601 and the connecting hole 602 allows the porous carrier plate 6 to conveniently slide the cleaning assembly 7 and effectively handle the impurities generated on the porous carrier plate, thereby ensuring that the porous carrier plate is always in good working condition during operation and improving the reliability and efficiency of the equipment.

[0043] It can be understood that the cleaning assembly 7 is a device for cleaning the porous supporting plate 6, including a cleaning housing 701, a fixing bracket 702, a rotating shaft 703, a bevel gear 704, a sleeve 705 and a T-shaped scraper 706.

[0044] The cleaning housing 701 is the housing part of the cleaning assembly, which is used to protect the internal components and adjust the cleaning angle. A fixing bracket 702 is provided inside the cleaning housing 701 to fix the position and direction of other components.

[0045] The fixed bracket 702 is rotatably connected to the rotating shaft 703. One end of the rotating shaft 703 is provided with a bevel gear 704, which can drive the movement of other parts during the working process. The other end of the rotating shaft 703 is rotatably connected to the inner wall of the cleaning shell 701 to play a supporting and stabilizing role.

[0046] The middle part of the rotating shaft 703 is rotatably connected to the inside of the sliding sleeve 705, and a T-shaped scraper 706 is provided on the outside of the sliding sleeve 705. The function of the T-shaped scraper 706 is to attach the scraper to the surface of the porous supporting plate 6 through the elastic rod 707 during the sliding process to scrape off the ash or other impurities on it and collect them into the cleaning shell 701.

[0047] Through the design and operation principle of the cleaning assembly 7, effective, rapid and precise cleaning operations can be achieved on the porous carrier plate 6. The device can efficiently remove ash and impurities on the surface of the porous carrier plate, improve the working efficiency and performance of the device, and extend its service life.

[0048] It is understood that the bevel gear 704 is rotatably connected to the bevel output gear 707, and the gear transmission mechanism therebetween can transmit the rotational motion to the bevel output gear 707. The bevel output gear 707 is fixedly connected to the central axis of the rotating fan 708.

[0049] The rotating fan 708 is connected to the cone output gear 707 and driven by the gear transmission mechanism during operation, thereby generating air flow. The rotating fan 708 is rotatably connected to the fan bracket 709, and the fan bracket 709 plays the role of supporting and stabilizing the rotating fan.

[0050] The fan bracket 709 is fixedly connected to the ventilation duct 710. The ventilation duct 710 is used to guide and distribute the air generated by the fan to a specified position. The fixed connection performance of the ventilation duct 710 ensures the stability and reliability of the air flow.

[0051] The ventilation duct 710 is fixedly connected to the air outlet of the blower 5. The blower 5 is a device for generating a strong airflow to discharge air from the ventilation duct 710 into the combustion chamber. Through this system, the air outlet of the blower 5 can provide strong air flow and combustion-supporting capacity requirements.

[0052] The working process of the utility model is as follows: the biomass raw material is placed on the feed conveyor belt, the feed conveyor belt transports the raw material to the combustion chamber, and then the biomass raw material enters the top of the porous carrier plate in the combustion chamber through the sealing plate, and then the biomass raw material is processed in the combustion chamber, and then the blower is started, and the blower generates airflow to drive the gear to rotate. Then the gear drives the rotating shaft to rotate, and then the rotation drives the sliding sleeve to rotate. When the sliding sleeve rotates to a certain position, it will make a reciprocating motion with the rotating groove on the rotating shaft, and then the inner side of the sliding sleeve rotates on the outer side of the sliding sleeve, and a T-shaped scraper is connected to the outer side of the sliding sleeve to clean the top of the porous carrier plate, and at the same time, the T-shaped scraper is pushed to the second discharge trough until it falls into the second discharge trough and enters the discharge conveyor belt.

[0053] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
