Description
Technical field
The utility model relates to a kind of coal-feeding tube road four-way insertion plate doors, belong to feeder technical field.
Background technique
With the economic degradation of electricity market, the coal quality situation and designing coal quality gap that power plant is purchased are increasing, receive
It is more and more to base moisture, cause the frequent chute blockage of unit, disconnected coal situation more serious.
It needs to be truncated to coal after chute blockage, with convenient to overhaul.Power plant's feeder mostly uses insertion plate door to be truncated at present
To coal, the unidirectional, stroke that existing insert plate gate of coal feeder has it is long it is easily-deformable, opening and closing is laborious, has leakage again, between some track grooves
Gap is larger, due to coal quality is thin, in coal there are the viscous sundries such as ash, be sticked in track groove, lead to rear storehouse hiding coal, cause plate card
Extremely, Guan Bushang.
Utility model content
The purpose of the utility model is to overcome the above deficiencies in the existing technologies, and provide a kind of structure design conjunction
The coal-feeding tube road four-way insertion plate door of reason, it is four that original insertion plate door one, which is divided, to solve phenomena such as insertion plate door is stuck.
The technical scheme in the invention for solving the above technical problem is: a kind of coal-feeding tube road four-way insertion plate door, including
Coal-feeding tube road and insertion plate door, which is characterized in that further include transmission device, pressure pin and sealing device；The insertion plate door and coal-feeding tube
Road is arranged vertically, and is slidably connected between insertion plate door and coal-feeding tube road, and the insertion plate door is provided with 4, and 4 insertion plate doors are two-by-two
Opposite arrangement, 4 opposite ends of insertion plate door are worked in coordination；The transmission device is connect with insertion plate door, and transmission device is to stretch
Contracting formula structure；The pressure pin is fixed with coal-feeding tube road, is used to support insertion plate door；The sealing device setting is in coal-feeding tube road and inserts
The outside of plate door contact surface, for preventing coal dust from revealing.
Furthermore, the insertion plate door is arranged through coal-feeding tube road, and the end of 4 insertion plate doors is in contact.
Furthermore, the end of the insertion plate door is triangular structure.
Furthermore, the transmission device is connected by gear, rack gear and insertion plate door.
Furthermore, the pressure pin is fixed on the lower section of insertion plate door, and pressure pin penetrates in coal-feeding tube road.
In use, insertion plate door guarantees radial expansion by transmission device, to reach closing or open the work in coal-feeding tube road
With.The front end of insertion plate door is triangular structure, is conducive to increase the effect that plate is pierced into coal dust.Pressure pin is welded on coal-feeding tube road
Together, it is used to support insertion plate door.Sealing device guarantees system sealing, prevents coal dust from revealing.
The utility model compared with prior art, has the following advantages that and effect: it is four that existing insertion plate door one, which is divided, is reduced
The stroke of insertion plate door, it is compact-sized, space occupied is reduced, improvement cost is low, and insertion plate door is triangle, is conducive to be pierced into coal dust
In, insertion plate door is switched in place.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is pair
The explanation of the utility model and the utility model is not limited to following embodiment.
Embodiment.
Referring to Fig. 1 to Fig. 4, coal-feeding tube road four-way insertion plate door in the present embodiment, including coal-feeding tube road 1, insertion plate door 2, pass
Dynamic device 3, pressure pin 4 and sealing device 5.
Wherein, coal-feeding tube road 1 is power plant's coal spout, and insertion plate door 2 is arranged vertically with coal-feeding tube road 1, and insertion plate door 2 runs through to coal
Pipeline 1, and be slidably connected between coal-feeding tube road 1；Insertion plate door 2 is provided with 4, and opposite arrangement forms one to 4 insertion plate doors 2 two-by-two
A 2 system of insertion plate door, the end of single insertion plate door 2 are triangular structure as shown in figure 4, being conducive to be pierced into coal dust, and 4 are inserted
The end of plate door 2 is in contact and works in coordination；Transmission device 3 is connected by gear, rack gear and insertion plate door 2, and is had axial
Scalability；Pressure pin 4 is welded and fixed with coal-feeding tube road 1, and penetrates in coal-feeding tube road 1, and pressure pin 4 is fixed on insertion plate door 2
Lower section is used to support insertion plate door 2；The outside in coal-feeding tube road 1 Yu 2 contact surface of insertion plate door is arranged in sealing device 5, for preventing coal
Powder leakage.
The present embodiment use process is as follows: coal-fired to enter coal-feeding tube road 1 from run coal bin as shown in Fig. 1-2, rotation passes
