Description
Technical field
The utility model is a kind of storehouse pump, in particular to a kind of pneumatic transporting ash cellar pump, is powder material pneumatic conveying skill
Art field.
Background technique
Positive pressure pneumatic ash handling system traditional at present generally uses the combination of gate valve+sealing valve+storehouse pump.Inlet valve is general
Using wearing-resisting gate valve or Wear-resisting rotating valve, which mainly has following three drawbacks: (1) self-defect of sealing structure is caused
Valve body Nei Yika ash, causes sealing valve to fit badly, sealing valve high failure rate；(2) dust causes the abrasion of sealing valve sealing surface
The service life of valve is not grown；(3) sealing valve is mounted on storehouse pump top, is installed separately with storehouse pump, storehouse pump pressure is to sealing plate
Active force and storehouse pump sealing form reaction, storehouse pump pressure is bigger, is more difficult to seal.
Summary of the invention
The utility model aims to solve the problem that the deficiencies in the prior art, provides a kind of compact-sized, and failure rate is low, installation
Overhaul convenient pneumatic transporting ash cellar pump.
The technical solution of the utility model is as follows:
A kind of pneumatic delivery bin pump of sealing device in pump, including including the pump housing (1), feeding device (2), sealing device
(3)。
The pump housing (1) include pump case (6), top guide bar (4), lower guide rod (5), pressing device (10), discharge nozzle (11),
Fluidized plate (12), air inlet (13), gas outlet (8).
The feeding device (2) includes that feed pipe (7), feedboard (14), upper cylinder (16), feedboard and upper cylinder connect
Bar (15).
The sealing device (3) includes that seal pipe (9), sealing plate (17), lower cylinder (19), sealing plate and lower cylinder connect
Bar (18).
The lower plane A of feed pipe (7) is bonded to form sealing with the upper plane B of feedboard (14)；The lower plane of seal pipe (9)
C and the upper plane D of sealing plate (17) fit closely to form sealing.
Preferably be that it is internal that seal pipe (9) is located at the pump housing (1), feed pipe (7) is located at pump housing import, and with the pump housing (1)
Integrally.
It is preferably that feedboard (14), sealing plate (17) are run in 1 cavity of the pump housing；Pass through spring attachment (10)
Lower guide rod (5) are held out against, so that top tight sealing plate (17), fits closely plane D thereon and the lower plane C of seal pipe (9), sealing
The upper plane D of the lower plane C and sealing plate (17) that manage (9) are embedded with wear-resistant material.
Its working principle of the invention: sealing plate (17) is opened, and the overbottom pressure in the pump housing 1 is discharged from gas outlet (8)；Feedboard
(14) it opens, dust is entered in pump case (6) by feed pipe (7)；When the interior dust of pump case (6) reaches set amount, into
Flitch (14) is closed, and sealing plate (17) is closed after delay, and charging terminates.
The invention has the advantages that a kind of pneumatic delivery bin pump of sealing device in pump, feed pipe and seal pipe position
In pump body, sealing plate and fitting closely by lower guide rod and spring attachment for seal pipe are realized, pump intracorporal pressure
Power is higher, and the sealing performance of sealing plate and seal pipe is better；Meanwhile feeding device is arranged in the pump pump housing import of this storehouse, sealing plate is " first
Closed after opening ", always among the protection in feeding device, and feedboard and sealing plate operation are respectively positioned on pump body, thoroughly solve
The defect problem of certainly conventional charging valve body Nei Yika ash, the sealing surface of sealing plate will not be worn by dust, it is ensured that sealing
The sealing performance of device reliably and with long-term；By the gate valve of traditional pneumatic ash transmitting system, sealing valve and storehouse pump " closing three is one ", structure
Compact, system configuration is reasonable, substantially reduces failure rate, as long as replacement sealing plate or feedboard, installation and repairing are more square when maintenance
Just.
