Abstract
Description
Technical Field
[0001] The invention relates to the technical field of gasifier feeding devices, and in particular to an adjustable gasifier rotary feeder. 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 fuel (such as biomass, coal, etc.) into the combustion chamber or reaction zone of the gasifier at a certain rate and method. At this time, the internal temperature and stable air pressure of the gasifier need to be maintained. The rotors inside the existing gasifiers are mostly cylindrical. The cylindrical rotors will wear out after a period of use. In addition, they are often in a high temperature state, which leads to an increase in the gap between the rotor and the gasifier shell. The gasifier will leak and the rotor can only be replaced. The rotor life is short, which increases the cost of the factory. Summary of the invention
[0003] In order to solve the defects that after the cylindrical rotor is often exposed to high temperature and self-consumption, the gap between the rotor and the gasifier shell increases, causing gas leakage in the gasifier and a short service life of the cylindrical rotor, the present invention provides an adjustable gasifier rotary feeder, which can still adjust the gap between the rotor and the gasifier shell to maintain in a reasonable range after the rotor is self-consumed, thereby preventing gas leakage in the gasifier and increasing the service life of the rotor.
[0004] The present invention provides the following technical solutions: It includes a gasifier body and a rotor, and the rotor is installed inside the gasifier body through a rotating shaft, and is characterized in that: the rotor is a conical rotor, and adjustment mechanisms are arranged at both ends of the rotating shaft for axial movement and adjustment of the conical rotor, and the adjustment mechanism includes a first connecting head and a second connecting head, and a rotor motor is arranged on the left side of the first connecting head, and the protruding end of the rotating shaft of the rotor motor is fixedly connected to the first connecting head, and a linkage block is installed at the center of the first connecting head, and an annular groove is arranged on the first connecting head to surround the linkage block, one end of the second connecting head is sleeved with the annular groove of the first connecting head and fixedly connected by a bolt pair, and the other end is fixedly connected to the rotating shaft, and the linkage block is inserted into the interior of the second connecting head by the connecting end of the second connecting head, and the rotating shaft is symmetrically divided into one end set as a threaded rod, and the other end is a smooth rod.
[0005] It is further characterized by: The regulating mechanism comprises a regulator and a fixing seat, the regulator is mounted on the gasifier body, two telescopic pushers are symmetrically mounted on the outside of the regulator, and threaded blocks are symmetrically arranged inside the regulator, the threaded blocks can be tightly fitted to form a threaded channel, the movable rod of the telescopic pusher passes through the regulator and is fixedly connected with the threaded block, the fixing seat is mounted on the side wall of the gasifier body away from the regulator, a yielding device is mounted on the fixing seat, and the smooth end of the rotating shaft is inserted into the fixing seat and is rotatably connected with the yielding device; The rotor motor is installed on the surface of an electric slider located below the rotor motor, and the electric slider is installed on the side plate of the gasification furnace body. The electric slider can move slowly on the side plate.
[0006] In the above technical solution, the technical effects and advantages provided by the present invention are: The arrangement of the first connector and the second connector in the adjustment mechanism ensures that the rotating shaft drives 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 be kept within a reasonable range, preventing the gasifier from leaking due to the increase in the gap, which is beneficial to prolonging the service life of the rotor. The setting of the regulator is conducive to the slow axial rotation of the rotating shaft, which is conducive to regulating the rotor to find a better gap position with the gasifier body, and prevents the rotating shaft from driving the conical rotor to move axially too fast to produce unpredictable effects, further improving the service life of the rotor; The setting of the stopper ensures that the rotating shaft can move axially while also limiting its movement, providing safety for the rotating shaft and indirectly increasing the service life of the rotor.

[0009] The present invention provides Figure 1-Figure 7 The adjustable gasifier rotary feeder shown in FIG. 1 includes a gasifier body 1 and a conical rotor 3 (see FIG. Figure 3 ), the conical rotor 3 is installed inside the gasifier body 1 through the rotating shaft 7, see Figure 1 , Figure 2 , Figure 4 , adjustment mechanisms are provided at both ends of the rotating shaft 7 for adjusting the axial movement of the conical rotor 3; See Figure 4 , Figure 5 , Figure 6 , Figure 7 The adjustment mechanism includes a first connector 4 and a second connector 5. A rotor motor 11 is arranged on the left side of the first connector 4. The end of the rotor motor 11 is fixedly connected to the first connector 4. A linkage block 6 is installed at the center of the first connector 4. An annular groove is arranged on the first connector 4 to surround the linkage block 6. One end of the second connector 5 is fitted with the annular groove of the first connector 4 (see Figure 5 ) and fixedly connected by bolts, the other end is fixedly connected to the rotating shaft 7, and the linkage block 6 is inserted into the second connector 5; See Figure 8 , the rotating shaft 7 is symmetrically divided into a threaded rod at one end and a smooth rod at the other end; See Figure 8 , Fig. 9The adjusting mechanism includes an adjuster 2 and a fixing seat 9. Two telescopic pushers 13 are symmetrically installed on the outside of the adjuster 2. A threaded block 8 is symmetrically arranged inside the adjuster 2. The movable rod of the telescopic pusher 13 passes through the adjuster 2 and the threaded block 8 for fixed connection; the adjuster 2 is installed on the gasifier body 1. When the connecting bolts of the first connector 4 and the second connector 5 are removed, 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 at the same time, the threaded block 8 will be pushed to fit tightly and form a threaded channel adapted to the rotating shaft 7. Because the adjuster 2 is fixed on the gasifier body 1, the rotating shaft 7 will be driven to rotate and thus produce axial movement; the second connector 5 is away from the first connector 4. When the first connector 4 and the second connector 5 are disconnected from the bolt connection, the threaded block 8 The formed threaded channel prevents the second connector 5 from being disengaged relatively quickly, resulting in the maximum axial movement of the rotating shaft 7 and the conical rotor 3, and the threaded channel causes the rotating shaft 7 to rotate slowly for axial movement, and the conical rotor 3 can slowly move axially to the optimal rotation position. The fixed seat 9 is installed on the side wall of the gasifier body 1 away from the regulator 2, and a stopper 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 stopper 10. When the gasifier is operating normally, the fixed seat 9 and the stopper 10 will be in a locked state, and the stopper 10 cannot be moved at this time. When the conical rotor 3 needs to be regulated, the axial movement of the rotating shaft 7 will cause the stopper 10 to move axially to the outside. When the connecting end of the stopper 10 is inside the fixed seat 9, it can be locked with the fixed seat 9 at any time to limit movement. At this time, the rotor motor 11 can be immediately closed; See Figure 1 The rotor motor 11 is installed on the surface of the electric slider 12 located below it. The electric slider 12 is installed on the side panel of the gasifier body 1. The electric slider 12 can move slowly on the side panel. When the conical rotor 3 is adjusted, the electric slider 12 is started until the second connector 5 is completely inserted into the first connector 4, and then the first connector 4 and the second connector 5 are fixed with bolts. At this time, starting the rotor motor 11 can make the conical rotor 3 continue to rotate normally.
