Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of preparation of bio-liquid fuel cellulose bio-liquid fuel, in particular to a bio-char conveying and cooling device containing a heat carrier. Background Art
[0002] Under the systematic action of catalysts, heat transfer oil heat carriers and other physical and mechanical process methods, the cellulose biomass is basically prepared into bio-liquid fuel after drying, crushing, pre-reactor, reactor, and distillation and separation of steam, gas, liquid and solid phases; at this time, the biochar solid-liquid mixture containing trace bio-oil and a large amount of heat transfer oil is put into a high-temperature high-speed centrifuge for solid-liquid separation; after that, the biochar solid-liquid mixture containing a small amount of heat transfer oil at a temperature of 280°C to 300°C enters the biochar conveying funnel by its own weight, and the driving motor with a reducer drives the double-screw auger to receive the biochar solid-liquid mixture and start conveying and cooling operations, and the biochar solid-liquid mixture eventually reaches a temperature below 100°C; finally, the biochar solid-liquid mixture at a temperature below 100°C is sent into the solid-liquid dispersion tank through the discharge port, and the solid biochar and liquid heat transfer oil are separated under the action of the extraction liquid.
[0003] However, it still has the following disadvantages in actual use:
[0004] The existing feed port is conical, and high-temperature materials are easy to stick to the wall of the feed port and block the feed port. Because it is a single-screw auger, there is no stirring function in the conveying process, and it can only push. The cooling contact area is insufficient, resulting in insufficient cooling and low production capacity, and cannot ensure safe production; the working chamber length and diameter of the single-screw auger are not enough, and the main shaft is a solid shaft without cooling function, resulting in the material temperature cannot be lowered, and the temperature requirement of the biochar solid-liquid mixture when it is sent into the solid-liquid dispersion tank cannot be met; there are no high-temperature seals at both ends of the single-screw auger equipment, and the biochar solid-liquid mixture is easy to come into contact with the air, causing safety accidents; there is no nitrogen in the feed port of the solid-liquid dispersion tank to isolate the air, which is easy to cause the gas in the solid-liquid dispersion tank to come into contact with the air and cause safety accidents. Summary of the invention
[0005] The purpose of the utility model is to provide a biochar conveying and cooling device containing a heat carrier to solve the problems raised in the above background technology.
[0006] A biochar conveying cooling device containing a heat carrier comprises a main body component and a connecting component;
[0007] The main body assembly includes a body;
[0008] The connecting assembly includes a motor-driven reduction assembly fixed to one end of the machine body, a first jacket fixed to the inner wall of the machine body, a group of double-helix auger shafts placed inside the machine body, a cut-in double-helix auger ring fixed to the surface of the double-helix auger shaft, a feed port fixed above one end of the machine body, and a discharge port fixed below the other end of the machine body.

[0013] Furthermore, the double helical auger ring and the double helical auger shaft are disconnected at the discharge port end after the material is transported and cooled, so as to form a double helical auger shaft without a helix.
[0014] Furthermore, a dispersion tank is sealedly connected to the lower side of the body, a nitrogen interface is fixedly connected to one side of the dispersion tank, a connecting plate is fixedly connected to the outer end of the connecting rod, and a bearing fixing frame is fixedly connected to the lower sides of the connecting rod and the mounting rod.
[0015] Furthermore, mounting frames are fixedly connected at both ends of the machine body, and one side of the motor is fixedly connected to an outer side surface of one of the mounting frames.
[0016] The working principle and working process of this utility model:
[0017] The biochar solid-liquid mixture containing a small amount of heat transfer oil separated from a high-temperature centrifuge at 280℃~300℃ and 2500r / min~3000r / min, enters the biochar solid-liquid mixture conveying and cooling equipment from the feed port, and the circulating coolant is pumped from the jacket inlet cooling interface and the double-helix auger shaft inlet cooling interface into the first jacket of the machine body and the hollow layer of the double-helix auger shaft respectively, and under the action of the mechanical conveying pressure of the double-helix auger ring, the biochar solid-liquid mixture is cooled by mass transfer on multiple cooling surfaces of the machine body and the double-helix auger shaft; as the temperature of the coolant rises and circulates to the jacket outlet cooling interface and the double-helix auger shaft outlet cooling interface, after being cooled by the cooling tower, it continues to be pumped and circulated into the jacket inlet cooling interface and the double-helix auger shaft inlet cooling interface for reciprocating operation.
[0018] Driven by a drive motor with a reducer and pushed by a double-helix auger ring, the biochar solid-liquid mixture is repeatedly and evenly subjected to a contact mass transfer process on the cooling surface during the process of being continuously squeezed, stirred and mixed to complete the transportation, thereby achieving a rapid drop in the temperature of the biochar solid-liquid mixture. When it reaches the discharge port, it reaches the required process temperature. At the discharge port, the biochar solid-liquid mixture that loses the spiral thrust forms a low-temperature physical damping dynamic accumulation zone state, which can effectively prevent the gas formed by the extract in the lower solid-liquid dispersion tank from flowing back through the gap in the material cavity of the double-helix auger ring into the working chamber of the upper high-speed centrifuge, and under the protection of the nitrogen input from the nitrogen interface and the coordinated action of mechanical mechanisms such as the bearing fixing frame with a shock absorber and the drive connecting plate, the low-temperature biochar solid-liquid mixture not higher than 100°C falls evenly and safely into the extraction tank body containing a large amount of extract for extraction, thereby achieving the solid-liquid separation operation of biochar and heat transfer oil.
