DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] See also Figure 1-2 , a dust-proof equipment for conveying powder alternative fuel, comprising:

[0029] A mobile flatbed truck 1 is provided with a conveyor belt 2 on the upper surface of the mobile flatbed truck 1. The powdered alternative fuel unloaded from the powdered alternative fuel conveying vehicle is conveyed to a silo for storing the powdered alternative fuel via the conveyor belt 2. A receiving bucket structure and a dust cover structure covering the conveyor belt 2 are provided on the upper surface of the mobile flatbed truck 1. The receiving bucket structure and the dust cover structure are continuously provided on the mobile flatbed truck 1.

[0030] The receiving bucket structure is used to receive the powdered alternative fuel dumped by the transport vehicle and guide the powdered alternative fuel to the conveyor belt 2 for transportation to prevent the powdered alternative fuel from generating dust. In the process of receiving the powdered alternative fuel unloaded from the vehicle through the conveyor belt 2, the receiving bucket structure is used to prevent dust from being generated during the unloading process.

[0031] The dust cover structure is used to prevent dust from being generated when the conveyor belt 2 transports powder as a substitute for fuel, ensuring that dust is reduced during the entire unloading process;

[0032] A dust prevention mechanism is provided on the receiving bucket structure because during the unloading process, some powder will be raised as dust when unloading and overflow from the receiving end of the receiving bucket structure. The dust prevention mechanism generates negative pressure in the receiving bucket structure to suck the dust emitted by the powder substitute fuel into the dust cover structure and transport it to the conveyor belt 2 under the dust cover structure for transportation, so as to avoid a large amount of dust escaping to the outside and causing environmental pollution and powder loss.

[0033] Furthermore, the receiving bucket structure includes a receiving cylinder 3, which is tilted and arranged on the upper surface of the mobile flatbed truck 1. The portion of the receiving cylinder 3 located above the conveyor belt 2 is provided with an avoidance opening 4 so that the powder will not be affected by the forward movement of the powder when the conveyor belt 2 is transporting the powder. The tilted upper end of the receiving cylinder 3 is used to receive the powder dumped by the transport truck instead of fuel. The cylinder structure of the receiving cylinder 3 is equivalent to a cover covering the powder receiving position to prevent the powder from raising dust.

[0034] Furthermore, an inclined material guide plate 5 is provided in the receiving cylinder 3, and the inclined material guide plate 5 is inclined downward from the receiving cylinder 3 toward the conveyor belt 2. The inclined material guide plate 5 is used to receive the powder substitute fuel dumped by the transport vehicle and guide it to the conveyor belt 2 for transportation, thereby increasing the height of the powder receiving and reducing the generation of dust, and then allowing the powder to slide freely onto the conveyor belt 2 for transportation.

[0035] Furthermore, an arc-shaped anti-dust baffle 6 is provided on the outer side of the upper end of the receiving cylinder 3 to block the rear of the transport vehicle's bucket when the transport vehicle dumps the powder substitute fuel to prevent dust. Dust generally spreads upward, and the arc-shaped anti-dust baffle 6 can effectively prevent the dust from spreading, and then the dust is captured back into the receiving cylinder 3 by the anti-dust mechanism.

[0036] Furthermore, the dust cover structure includes an outer cover 7 horizontally arranged on the upper surface of the mobile flatbed truck 1 and covering the conveyor belt 2. The two ends of the outer cover 7 are flared to allow the two ends of the conveyor belt 2 to extend out without hindering the conveyor belt 2 from conveying powder. One end of the outer cover 7 is docked with the receiving cylinder 3 and is connected to the receiving cylinder 3 through the avoidance opening 4 to connect the dust cover structure with the receiving bucket structure, leaving no space for powder to escape, and ensuring the continuity of the conveyor belt 2 in conveying powder.

[0037] Furthermore, the dust prevention mechanism includes an axial flow fan 8, which is arranged above the outer cover 7. The air inlet of the axial flow fan 8 is connected to the air inlet tube 9. The other end of the air inlet tube 9 extends from the upper side of the receiving cylinder 3 into the receiving cylinder 3. An air collecting cover 10 is provided at one end of the air inlet tube 9 extending into the receiving cylinder 3. The air outlet of the axial flow fan 8 is connected to the air outlet tube 11.

[0038] An inclined discharge barrel 12 is provided on the upper surface of the outer cover 7 and below the air outlet duct 11. The lower end of the inclined discharge barrel 12 extends into the outer cover 7. The upper end of the inclined discharge barrel 12 is connected to a collecting hopper 13 and is communicated with the collecting hopper 13. One side of the collecting hopper 13 is an inclined surface. An inclined baffle 14 extending downward from the inclined surface of the collecting hopper 13 is provided at the connection position between the collecting hopper 13 and the inclined discharge barrel 12. A space is left between the lower end of the inclined baffle 14 and the inner wall of the inclined discharge barrel 12 for powder to replace fuel dust to enter. The lower end of the air outlet duct 11 extends into the collecting hopper 13 and is arranged toward the inclined surface of the collecting hopper 13.

[0039] Specifically, by starting the axial flow fan 8, the axial flow fan 8 draws out the air in the receiving cylinder 3 through the air inlet 9, creating a negative pressure in the receiving cylinder 3, sucking in the dusty powder so that it moves forward along with the powder transported by the conveyor belt 2. The powder sucked in by the axial flow fan 8 is then transported to the collecting hopper 13 through the air outlet 11, and enters the inclined discharge barrel 12 along the collecting hopper 13 and the inclined baffle 14, so that the small amount of powder sucked in is sent into the outer cover 7 through the inclined discharge barrel 12 and falls on the powder transported by the conveyor belt 2. Among them, the position where the lower end of the air outlet 11 extends into the collecting hopper 13 and the inclined baffle 14 both play a windproof role, preventing wind from being directly introduced into the inclined discharge barrel 12, so that the air outlet 11 only plays the role of conveying powder.

[0040] Furthermore, a first dustproof net 15 is provided on the top of the collecting hopper 13 to prevent the powder substitute fuel dust entering the collecting hopper 13 from overflowing, so as to more comprehensively prevent dust.

[0041] Furthermore, a second dust-proof net 16 covering the outside of the wind collecting hood 10 is provided on the inner side of the receiving cylinder 3. This is mainly reflected in that the dust-proof mechanism does not mainly suck the powder into the outer cover 7, but sucks the dusty powder into the receiving cylinder 3 and blocks it through the second dust-proof net 16. However, the second dust-proof net 16 will not affect the circulation of the sucked air.

[0042] To sum up, this device assumes dust prevention equipment between the vehicle transporting powder alternative fuel and the silo loaded with powder alternative fuel. When the powder unloaded by the vehicle is received by the conveyor belt, and during the transportation to the silo, the receiving bucket structure and the dust cover structure can effectively prevent the powder from escaping. At the same time, the anti-dust mechanism sucks the powder into the receiving bucket structure, further preventing the powder from escaping, avoiding environmental pollution caused by dust during the transportation of powder alternative fuel, and reducing the losses caused by dust during the transportation of powder alternative fuel.

[0043] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
