Description

Technical Field

[0001] The utility model belongs to the technical field of biomass fuel transportation, in particular to a transportation device for biomass fuel production. Background Art

[0002] Biomass fuel refers to the material that uses biomass materials as fuel for combustion. These biomass materials mainly come from agricultural and forestry waste, such as straw, sawdust, bagasse, rice bran, etc. Compared with fossil fuels, biomass fuel produces less pollution during the combustion process, so it is regarded as a more environmentally friendly energy source. In the production process of biomass fuel, in order to accurately control the material transportation, screw conveyors are often used to undertake the material transportation operation in each process;

[0003] At present, since the raw materials of biomass fuel come from biomass such as straw, it contains a lot of water. As a result, when conveying materials, the crushed materials adhere to the surface of the spiral blades and cannot be directly used. At the same time, it will form dirt or even blockage, affecting the subsequent feeding effect.

[0004] In order to solve the above problems, the present application proposes a conveying device for biomass fuel production. Utility Model Content

[0005] The purpose of the utility model is to provide a conveying device for biomass fuel production, which solves the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a conveying device for biomass fuel production, comprising: a screw conveyor and a hopper installed at one end thereof; a cleaning part is arranged above the screw conveyor, a positioning shaft is arranged inside the cleaning part, cleaning cotton for cleaning spiral blades is arranged at equal intervals outside the positioning shaft, and real-time cleaning of the spiral blades avoids blockage during material feeding and transmission; a side seat is arranged at one end of the cleaning part, a transfer shaft block is arranged inside the side seat, and a clamping block connected with the positioning shaft and the spiral blade rotating shaft is arranged at one end of the transfer shaft block, so as to form an assembly structure that is convenient for assembly, disassembly, maintenance and use.

[0008] Furthermore, side plates connected and fixed to the screw conveyor are arranged on both sides of the cleaning part, and positioning plates for installing positioning shafts are also arranged at both ends of the cleaning part.

[0009] Furthermore, a connecting plate for rotatably mounting adjacent transfer shaft blocks is disposed inside the side seat, and an electric telescoping device for driving the connecting plate to move forward and backward is also disposed inside the side seat.

[0010] Furthermore, a transmission belt is installed on the outer side of the other end of the adapter shaft block, which is used to transmit the rotational force of the spiral blade shaft to the positioning shaft.

[0011] Furthermore, a card slot for card block engagement connection is provided inside one end of the positioning shaft and inside one end of the spiral blade rotating shaft.

[0012] Furthermore, a positioning groove for installing the spiral blade shaft so that it protrudes outward is formed at one end of the screw conveyor.

[0013] Furthermore, the cleaning cottons are closely arranged adjacently to each other to include spiral leaves to prevent omission.

[0014] The utility model has the following beneficial effects:

[0015] The utility model can intermittently rub the surface of the spiral blade with cleaning cotton after adding a cleaning part, remove the moisture on the surface and push out the attached materials, so as to form a stable material discharge effect. At the same time, the cleaning method can also be used to clean the middle area of ​​the spiral blade in real time to prevent the material from being blocked due to long-term adhesion. Compared with the existing screw conveyor, it can greatly improve the conveying effect of moisture-containing materials, improve work efficiency and enrich the functionality of the equipment;

[0016] The utility model utilizes the installation of a side seat to directly install the cleaning part above the screw conveyor, and then utilizes the electric telescopic device to drive the transmission belt to connect with the positioning shaft and the spiral blade rotating shaft.
