[0036] Embodiment: please refer to the attached Figures 1-3 The present application provides a kind of technical scheme: a kind of alternative fuel distribution conveying system, it includes:

[0037] Buffer bin 1 is connected with feeding equipment;

[0038] Double discharge port conveying mechanism 6 is located in the buffer bin 1 directly below, and the feed inlet of double discharge port conveying mechanism 6 is connected with the bottom circular mouth of buffer bin 1 and is communicated, double discharge port conveying mechanism 6 has two discharge ports, and is communicated with two silos respectively;

[0039] Arch breaking mechanism 2 is provided with multiple, and is evenly installed on buffer bin 1, each arch breaking mechanism 2 can be stirred loose to the material accumulated in the wall of buffer bin 1;

[0040] And an automatic spraying system is installed on the inner top of the buffer bin 1, and the automatic spraying system is controlled by the temperature monitoring system 4 to spray and extinguish the burning materials in the buffer bin 1.

[0041] In the embodiment, the double-outlet conveying mechanism 6 is composed of two spiral conveyors arranged side by side and oppositely, and the two spiral conveyors are located on the same horizontal plane.

[0042] In the embodiment, the spiral conveyor comprises:

[0043] The conveying box 11;

[0044] The variable-pitch spiral blade 9 is rotatably installed in the barrel cavity of the conveying box 11;

[0045] The bearing seat 12 is fixed on one side of the conveying box 11, and the rotating shaft connected with the variable-pitch spiral blade 9 is rotatably installed in the bearing seat 12;

[0046] The variable-frequency motor 8 is fixed on the bearing seat 12 and drives the rotating shaft to rotate;

[0047] It should be noted that the variable-frequency motor can adjust the spiral speed according to the required amount of materials at the rear, and can realize automatic reverse rotation according to the running condition.

[0048] And the discharge hopper 13 is installed at the discharge port of the conveying box 11.

[0049] In the embodiment, the pitch of the variable-pitch spiral blade 9 gradually increases along the discharge direction, which can reduce the material conveying resistance.

[0050] In the embodiment, the part connecting the buffer bin and the outlet end of the conveying box 11 is in an arc structure;

[0051] It should be noted that the circular arc design can reduce the pushing resistance of the double-outlet conveying spiral when there is a certain material layer thickness in the buffer bin 1.

[0052] In the embodiment, the arch breaking mechanism 2 is composed of a transmission gear box 201, an arch breaking motor 202 and an arch breaking assembly, wherein the transmission gear box 201 is fixed on the side wall of the buffer bin 1, the top of the transmission gear box 201 is fixed with the arch breaking motor 202, and the driving end of the arch breaking motor 202 is connected with the driving gear in the transmission gear box 201.

[0053] The arch breaking assembly is arranged in the buffer bin 1 and connected with the driven gear in the transmission gear box 201 through a connecting shaft, and the arch breaking assembly can stir and loosen the materials accumulated on the wall of the bin, so that the materials in the bin will not be arching.

[0054] In the embodiment, the automatic spraying system comprises:

[0055] The atomizing nozzles 5 are arranged in plurality and evenly arranged on the inner top wall of the buffer bin 1;

[0056] It should be noted that the number of the atomizing nozzles 5 can be set according to the size of the buffer bin 1;

[0057] The water injection pipeline 16 is connected with the water supply device at the other end thereof.

[0058] The water injection pipeline 16 is sequentially provided with a pressure regulating valve 15 and an electromagnetic valve 14 along the water injection direction thereof.

[0059] In the embodiment, the temperature monitoring system 4 comprises a screw type temperature sensor and a spark detector.

[0060] It should be noted that the temperature monitoring system 4 can monitor the temperature in the bin and whether sparks are generated. If the temperature is higher than the set temperature value or sparks are generated, an alarm signal is sent out and the automatic spraying system is controlled to spray water for cooling.

[0061] In the embodiment, the top of the buffer bin 1 is provided with a radar material level meter 3 for monitoring the material level in the buffer bin 1, reflecting the material level height in the bin and adjusting the speed of the feeding speed.

[0062] In the embodiment, the sidewall of the buffer bin 1 is further provided with an inspection observation door 10 and a pressure relief valve 7.

[0063] The pressure relief valve 7 is used to deal with the possible dust flash explosion, and the inspection observation door 10 is used for inspection of the inside of the buffer bin 1.

[0064] In the specific implementation, the alternative fuel is delivered into the buffer bin 1 of the material distribution system by the feeding device. The buffer bin 1 can store a part of the material, maintaining the balance and stability of the material distribution system. The material height in the buffer bin 1 can be monitored by the radar material level meter 3. If the material level exceeds the set height, the material level meter automatically sends a signal to the control system to reduce the amount of incoming material, avoiding the buffer bin 1 being full. If the material level is lower than the set height, the material level meter automatically sends a signal to the control system to increase the amount of incoming material, avoiding the buffer bin 1 being empty. That is, the radar material level meter can maintain the dynamic balance of the material in the buffer bin 1.

[0065] If only a single line needs to be operated, the material on the other side can be accumulated to a certain extent. At this time, the arch breaking motor 2 provided on the bin wall can be started to make the material in the non-moving screw section not accumulated too high. The material in the buffer bin 1 can be conveyed to the designated downstream bin through the two discharge ports of the lower discharge port conveying mechanism 6, so as to enter the designated feeding point.

[0066] In the above process, if the temperature in the buffer bin exceeds the set value or sparks are generated, there is a risk of fire, at which time the electromagnetic valve of the automatic sprinkler system can be opened by the control system to spray and cool the buffer bin 1 through the atomizing nozzle.
