Measure the blocking of exhaustor in this kind of storehouse pump.Another core of the present utility model is to provide a kind of bag
Including the pneumatic ash transmitting system of above-mentioned storehouse pump, fill process is the most smooth and easy.
Refer to Fig. 1, Fig. 1 structure by the specific embodiment of this utility model provided storehouse pump
Schematic diagram.
In a kind of specific embodiment of this utility model provided storehouse pump, storehouse pump includes the pump housing, row
The parts such as trachea 4, exhaust circle overhead-valve 1 and detection valve 2.Wherein, exhaust circle overhead-valve 1 is even
Being connected between the pump housing and exhaustor 4, when opening exhaust circle overhead-valve 1, the residual air in the pump housing can depend on
Secondary discharge the pump housing by exhaust circle overhead-valve 1, exhaustor 4, so that the material in ash bucket 5 is suitable
Profit enters pump body.The detection valve 2 whether blocked for detecting exhaustor 4 is arranged on aerofluxus
On pipe 4.
When using detection valve 2, first storehouse out of service pump, open detection valve 2 the most again, with
The eyes of testing staff are caused by the ash discharged by the exhaust circle overhead-valve 1 opened when exempting from storehouse pump operation
Damage；When detection, if exhaustor 4 has negative pressure, then explanation exhaustor 4 is unobstructed, aerofluxus
Normally, ash bucket 5 top is without dust stratification, if exhaustor 4 is without negative pressure, then explanation exhaustor 4 blocks up
Plug or ash bucket 5 top dust stratification；Upon completion of the assays, detection valve 2 cuts out and puts in place, in case
Leak-stopping ash, abrasion.
Visible, testing staff can select reasonable time to enter exhaustor 4 according to actual needs
Row detection, in order to detect and find the blockage problem of exhaustor 4 in time, the operation side when detection
Just effective, decrease maintenance workload, reduce maintenance cost, additionally, testing staff can
Ash bucket 5 top dust stratification situation is had an anticipation, and to the stopping state of exhaustor 4 and ash
The judgement of the 5 dust stratification situations that struggle against is more directly perceived, thus ensures the stable operation of storehouse pump.
Specifically, detection valve 2 can select manual ball valve.Manual ball valve is simple to operate, opening and closing
Rapidly, and it is not easily blocked in valve, easy to maintenance, and valve sealing face is not easily susceptible to invading of medium

Work as position, and connecting tube 3 communicates with exhaustor 4.The setting of connecting tube 3 is easy to detect valve
The installation of 2.Wherein, connecting tube 3 can be connected to exhaustor 4 by welding or other modes.
It is of course also possible to by other means detection valve 2 is linked together with exhaustor 4.
Each embodiment above-mentioned detects valve 2 can be connected in several ways with connecting tube 3,
Specifically external screw thread can be set in connecting tube 3, easy to make, detection valve 2 and connecting tube 3
It is threaded connection, specifically can be by direct for connecting tube 3 and with suitable female thread inspection
Side valve 2 is attached, or by carrying female transit joint will be provided with externally threaded inspection
Side valve 2 links together with connecting tube 3.It is of course also possible to by valve 2 will be detected and is connected
Pipe 3 carries out welding, Flange joint or other modes realize the company of detecting valve 2 with connecting tube 3
Connect.
Connecting tube 3 in each embodiment above-mentioned can select straight tube, and the axle of connecting tube 3
8 centimetres to 12 centimetres specifically can be selected, to reduce the resistance pair of connecting tube 3 to length range
The impact of testing result, and meet ergonomics.Certainly, the shape of connecting tube 3 and each
The size in individual direction is it can also be provided that other forms.Preferably, the axial length of above-mentioned straight tube
Could be arranged to 10 centimetres, easy to operate, do not interfere with the operation of other equipment or parts, and
Be conducive to avoiding affecting testing result because connecting tube 3 blocks.It addition, connecting tube 3 and aerofluxus
Angle between pipe 4 can have multiple set-up mode, for example, it is possible to make connecting tube 3 relative to
Exhaustor 4 is obliquely installed, and arranges one end of detection valve 2 in connecting tube 3 relative to the other end
It is positioned at upside, thus the beneficially discharge of residual air in exhaustor 4.
Detection valve 2 position is set can have many on exhaustor 4 in each embodiment above-mentioned
Plant and select.Generally, it is connected by adpting flange between exhaustor 4 with exhaust circle overhead-valve 1, excellent
Selection of land, can arrange a detection valve 2 on exhaustor 4, and detect valve 2 and adpting flange
The scope of distance value be 28 centimetres to 32 centimetres, for example, it is possible to be 30 centimetres, operation side
Just, ergonomics is met.Certainly, the connected mode of exhaustor 4 and exhaust circle overhead-valve 1 is not
It is limited to this.
Or, the detection valve 2 in each embodiment above-mentioned can also arrange at least two, with
Just the stopping state being exhausted on pipe 4 diverse location carries out detection investigation, is conducive to detecting
The particular location of plugging point on exhaustor 4.It is alternatively possible to along aerofluxus on exhaustor 4
The axially arranged at least two detection valve 2 of pipe 4, such that it is able to according to actual needs to exhaustor 4
Various location in the axial direction detects.Specifically, above-mentioned at least two can be detected
Valve 2 being axially configured equally spacedly, to reduce manufacture difficulty along exhaustor 4.
In above-described embodiment, detection valve 2 outlet side can connect further piezometer or
Other pressure-detecting devices, so that convenient the blocking up exhaustor 4 intuitively of testing staff
Plug situation detects.Alternatively, the outlet side at detection valve 2 can connect a detection
Pipe, is connected to piezometer on this detection pipe.It is of course also possible to realize by other means right
The detection of exhaustor 4.
Except above-mentioned storehouse pump, this utility model also provides for one and includes storehouse disclosed in above-described embodiment
The pneumatic ash transmitting system of pump, this pneumatic ash transmitting system is owing to have employed above-mentioned storehouse pump, fill process
The most smooth and easy.The structure of other each several parts of this pneumatic ash transmitting system refer to prior art, this
Literary composition repeats no more.
In this specification, each embodiment uses the mode gone forward one by one to describe, and each embodiment emphasis is said
