Description

Technical Field

[0001] The utility model relates to the technical field of gasifier feeding devices, and particularly relates to an adjustable rotary feeder for a gasifier. Background Art

[0002] Gasifier feeders are widely used in various gasifier systems, especially in the fields of biomass gasification, coal gasification, etc. The main function of the gasifier feeder is to feed solid fuels (such as biomass, coal, etc.) into the combustion chamber or reaction zone of the gasifier at a certain rate and in a certain manner. At this time, a high temperature and stable air pressure need to be maintained inside the gasifier. Most of the existing rotors inside the gasifier are cylindrical. After being used for a period of time, the cylindrical rotor itself will be worn. Coupled with being in a high-temperature state for a long time, the gap between the rotor and the gasifier shell will increase, resulting in air leakage in the gasifier. The rotor can only be replaced forcedly, and the rotor life is relatively low, increasing the cost consumption of the factory. Summary of the Utility Model

[0003] Aiming at the defect that after the cylindrical rotor is self-consumed at high temperature for a long time, the gap between the rotor and the gasifier shell increases, resulting in air leakage in the gasifier and the low life of the cylindrical rotor, the utility model provides an adjustable rotary feeder for a gasifier. After the rotor is self-consumed, the gap between the rotor and the gasifier shell can still be adjusted and maintained within a reasonable range, preventing air leakage in the gasifier and increasing the service life of the rotor.

[0004] The utility model provides the following technical solutions:

[0005] It includes a gasifier body and a rotor. The rotor is installed inside the gasifier body through a rotating shaft. It is characterized in that: the rotor is a conical rotor, and adjusting mechanisms are arranged at both ends of the rotating shaft for axially moving and adjusting the conical rotor.

[0006] It is further characterized in that:

[0007] The adjusting mechanism includes a first connecting head and a second connecting head. A rotor motor is arranged on the left side of the first connecting head. The end of the rotating shaft extending out of the rotor motor is fixedly connected to the first connecting head. A linkage block is installed at the central part of the first connecting head. An annular groove is arranged on the first connecting head around the linkage block. One end of the second connecting head is sleeved in the annular groove of the first connecting head and fixedly connected through bolts, and the other end is fixedly connected to the rotating shaft. The linkage block is inserted into the interior of the second connecting head from the connecting end of the second connecting head;

[0008] One end of the rotating shaft is symmetrically and evenly divided into a threaded rod, and the other end is a smooth rod;

[0009] The adjusting mechanism includes a regulator and a fixed seat. The regulator is installed on the gasifier body. Two telescopic pushers are symmetrically installed outside the regulator. Threaded blocks are symmetrically arranged inside the regulator. The threaded blocks can be closely fitted to form a threaded channel. The movable rods of the telescopic pushers pass through the regulator and are fixedly connected to the threaded blocks. The fixed seat is installed on the side wall of the gasifier body far from the regulator. A reliever is installed on the fixed seat. The smooth end of the rotating shaft is inserted into the fixed seat and is rotatably connected to the reliever;

[0010] The rotor motor is installed on the surface of the electric slider located below it. The electric slider is installed on the side plate of the gasifier body. The electric slider can move slowly on the side plate.

[0011] In the above technical solution, the technical effects and advantages provided by the present utility model are:

[0012] The settings of the first connecting head and the second connecting head in the adjusting mechanism ensure that the rotating shaft can drive the conical rotor to move axially. For the conical rotor after self-consumption, the gap between the rotor and the gasifier body can still be adjusted to remain within a reasonable range, preventing the gasifier from leaking due to an increased gap, which is beneficial to increasing the service life of the rotor;

[0013] The setting of the regulator is beneficial to the slow axial rotational movement of the rotating shaft, which is beneficial to regulating the rotor to find a better gap position with the gasifier body, and further prevents the rotating shaft from driving the conical rotor to move axially too fast, resulting in unpredictable effects, and further improving the service life of the rotor;

[0014] The setting of the reliever ensures that the rotating shaft can move axially while also restricting its movement, providing safety protection for the rotating shaft and indirectly increasing the service life of the rotor. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present utility model provides an adjustable rotary feeder for a gasifier as shown in Figures 1-7 , which includes a gasifier body 1 and a tapered rotor 3 (see Figure 3 ). The tapered rotor 3 is installed inside the gasifier body 1 through a rotating shaft 7, see Figure 1 , Figure 2 , Figure 4 . Adjusting mechanisms are provided at both ends of the rotating shaft 7 for adjusting the axial movement of the tapered rotor 3;

[0027] See Figure 4 , Figure 5 , Figure 6 , Figure 7 . The adjusting mechanism includes a first connector 4 and a second connector 5. A rotor motor 11 is provided on the left side of the first connector 4. The end of the rotating shaft of the rotor motor 11 extends out and is fixedly connected to the first connector 4. A linking block 6 is installed at the central part of the first connector 4. An annular groove is provided on the first connector 4 around the linking block 6. One end of the second connector 5 is sleeved in the annular groove of the first connector 4 (see Figure 5 ) and fixedly connected by bolts, and the other end is fixedly connected to the rotating shaft 7. The linking block 6 is inserted into the second connector 5;

[0028] See Figure 8 . One end of the rotating shaft 7 is symmetrically and evenly divided into a threaded rod, and the other end is a smooth rod;

[0029] See Figure 8 , Figure 9, the adjusting mechanism includes a regulator 2 and a fixed seat 9. Two telescopic pushers 13 are symmetrically installed outside the regulator 2. Threaded blocks 8 are symmetrically arranged inside the regulator 2. The movable rods of the telescopic pushers 13 pass through the regulator 2 and are fixedly connected to the threaded blocks 8. The regulator 2 is installed on the gasifier body 1. When the connecting bolts of the first connector 4 and the second connector 5 are disassembled, the rotor motor 11 rotates. At this time, due to the action of the linkage block 6, the second connector 5 will rotate. When the telescopic pushers 13 work simultaneously, the threaded blocks 8 will be pushed to fit tightly and form a threaded channel adapted to the rotating shaft 7. Since the regulator 2 is fixed on the gasifier body 1, the rotating shaft 7 will be driven to rotate and then generate an axial movement. The second connector 5 moves away from the first connector 4. When the first connector 4 and the second connector 5 are disengaged from the bolt connection, the threaded channel formed by the threaded blocks 8 prevents the second connector 5 from detaching too quickly, resulting in the maximum axial movement of the rotating shaft 7 and the conical rotor 3. Moreover, the threaded channel will cause the rotating shaft 7 to slowly rotate for axial movement, and the conical rotor 3 can slowly axially move to the optimal self-rotation position. The fixed seat 9 is installed on the side wall of the gasifier body 1 away from the regulator 2. A reliever 10 is installed on the fixed seat 9. The smooth end of the rotating shaft 7 is inserted into the fixed seat 9 and is rotatably connected to the reliever 10. When the gasifier is working normally, the fixed seat 9 and the reliever 10 will be in a locked state, and at this time, the reliever 10 cannot move. When the conical rotor 3 needs to be adjusted, the axial movement of the rotating shaft 7 will cause the reliever 10 to axially move outward. The connecting end of the reliever 10 can be locked with the fixed seat 9 at any time to limit the movement inside the fixed seat 9. At this time, just turn off the rotor motor 11 immediately;

[0030] See Figure 1 , the rotor motor 11 is installed on the surface of an electric slider 12 located below it. The electric slider 12 is installed on the side plate of the gasifier body 1. The electric slider 12 can move slowly on the side plate. When the conical rotor 3 is adjusted properly, start the electric slider 12 until the second connector 5 is completely inserted into the first connector 4, and then use bolts to fix the first connector 4 and the second connector 5. At this time, starting the rotor motor 11 can make the conical rotor 3 continue to rotate and work normally.
