Detailed description of the invention
First purpose of the present invention is to provide a kind of storage tank, the structure design of this storage tank
Can be effectively prevented air bleeding valve blocking, second object of the present invention is to provide one and includes
State the powder material transport vehicle of storage tank.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical side in the embodiment of the present invention
Case is clearly and completely described, it is clear that described embodiment is only the present invention one
Divide embodiment rather than whole embodiments.Based on the embodiment in the present invention, this area is general
The every other embodiment that logical technical staff is obtained under not making creative work premise,
Broadly fall into the scope of protection of the invention.
Refer to Fig. 1-Fig. 3, the storage tank that the embodiment of the present invention provides, including tank body 1, set
The material lid 2 being placed on tank body 1 and exhaust apparatus 3, wherein exhaust apparatus 3 includes air bleeding valve 34
With connecting tube 31, wherein to be positioned at tank body 1 outside for air bleeding valve 34, the outlet side of connecting tube 31 with
The inlet end of air bleeding valve 34 is tightly connected, and the inlet end of connecting tube 31 stretches into tank body 1 and tank
The internal connection of body 1, and the air inlet of connecting tube 31 is fixed and is coated with filter cloth.
During the storage tank that the application embodiment of the present invention provides, it is coated with filter due to fixing at air inlet
Be covered with filter cloth on cloth, the i.e. air inlet of connecting tube 31, the most then when giving tank body 1 aerofluxus, tank
Gas in body 1 need to remain in such tank body 1 through filter-cloth filtering when entering connecting tube 31
Powder grain material may proceed to stay in tank body 1 due to filter-cloth filtering, without entering connecting tube 31
In so enter air bleeding valve 34, and then avoid powder enter air bleeding valve 34 result in blockage, protect
Demonstrate,prove the normal work of bulk powder goods tanker.
Wherein, connecting tube 31 through the wall of tank body 1, connecting tube 31 can and the wall of tank body 1 between
Full weld, to ensure the sealing between connecting tube 31 and tank body 1.Air bleeding valve 34 can be ball valve.
In order to increase the area of air inlet, connecting tube 31 can include the straight tube 312 being interconnected
With conical pipe 311, the outlet side of straight tube 312 is tightly connected with the inlet end of air bleeding valve 34, straight tube
The inlet end of 312 is connected with the outlet side of conical pipe 311, and be relatively large in diameter the one of conical pipe 311
End is inlet end, and one end that i.e. diameter of conical pipe 311 is less is outlet side.So by connecting tube
The part of the air inlet of 31 is set to conical pipe 311, can accordingly increase the area of air inlet, with
Increase throughput, reduce venting duration.Should fix on the air inlet of this conical pipe 311 and be coated with
Filter cloth.Angle between sidewall and its axis of conical pipe 311 can be 45 °, the most all right
For other angle, in this no limit.
Further, in order to increase throughput further, reduce venting duration, it is also possible at cone
Offer multiple air inlet in the tapered wall of shape pipe 311, and tapered wall outer sheath is provided with the first filter
Cloth, other in such tank body 1 can also enter conical pipe from the hole of the sidewall of conical pipe 311
311, and the first filter cloth can filter the powder in gas, so adds total face of air inlet
Long-pending, it is simple to shorten venting duration.And offer air inlet on the sidewall of conical pipe 311, it is simple to
Fall within the buildup landing of conical pipe 311 sidewall.Multiple air inlets on conical pipe 311 can divide many
Column distribution.
Can be threaded connection between inlet end and the outlet side of conical pipe 311 of straight tube 312,
And one end of the first filter cloth is anchored between the screw thread of conical pipe 311 and the screw thread of straight tube 312,
Will one end of the first filter cloth be placed directly in the screw thread of conical pipe 311 and straight tube 312 screw thread it
Between, then the screw thread of the screw thread of conical pipe 311 with straight tube 312 is mutually fastened, now conical pipe
Compact siro spinning technology between 311 and straight tube 312, simultaneously by the first filter cloth clamping.It is arranged such, more
It is easy to the replacing of the first filter cloth, also allows for the dismounting between conical pipe 311 and straight tube 312.Certainly,
This section of first filter cloth can also be fixing by binding, and steel wire or rope yarn i.e. can be utilized the
One filter cloth is bundled in the outside of straight tube 312.Can also directly weld between straight tube 312 and conical pipe 311
Connect, in this no limit.
This exhaust apparatus 3 can also include the fixing bottom 38 being covered in conical pipe 311 inlet end,
And also offer multiple air inlet on bottom 38, and the outside of bottom 38 is fixed and is coated with second
Filter cloth, so that the second filter cloth is fitted with bottom 38, can protect the second filter cloth indeformable.
Wherein the second filter cloth can utilize steel wire or rope yarn to be bundled on bottom 38 by the second filter cloth.
Further, the outer wall of conical pipe 311 is provided with boss, also includes being set in taper
The retainer ring 37 abutted outside pipe 311 and with boss, the other end of the first filter cloth is fixed on retainer ring
Between 37 and boss, so the other end of the first filter cloth can be anchored on retainer ring 37 and boss,
Retainer ring 37 and boss mutually fit tightly the first filter cloth clamping.Achieve the first filter cloth
Two ends are fixed.This end of first filter cloth can also directly be followed closely on boss, in this no limit.
Retainer ring 37 can directly be bolted with boss, with this realize retainer ring 37 and boss it
Between abut.
It addition, retainer ring 37 can by multiple bolts 36 being circumferentially distributed even with bottom 38
Connect, boss between bottom 38 and retainer ring 37, so can realize simultaneously retainer ring 37 with
The connection of the abutting of boss and bottom 38 and conical pipe 311 inlet end, easily facilitates bottom 38 and solid
Determine the dismounting of ring 37.
Certainly bottom 38 can also directly weld with conical pipe 311 inlet end, in this no limit.
In order to prevent the second filter cloth dislocation, the inlet end end of conical pipe 311 can have groove,
And there is on bottom 38 projection with groove fit, the edge of the second filter cloth is pressed in conical pipe 311
Inlet end and bottom 38 between, such second filter cloth is pressed between groove and projection so that
The installation of the second filter cloth is more firm.
Wherein, in order to ensure smooth in exhaust, the area sum of multiple air inlets is a, the first filter cloth
Being b with the mesh number of the second filter cloth, the area sum of the first filter cloth and the second filter cloth is c, ball valve
A diameter of d, wherein a*b*c >=d.
In order to change the discharge directions of air bleeding valve 34, also include being positioned at connecting tube 31 and air bleeding valve 34
Between steel elbow 32, i.e. can change the installation direction of air bleeding valve 34, steel by steel elbow 32
The inlet end of elbow 32 is connected with the outlet side of connecting tube 31, the outlet side of steel elbow 32 and aerofluxus
The inlet end of valve 34 connects, and can weld or threaded between steel elbow 32 with connecting tube 31.
Can also be connected between steel elbow 32 with air bleeding valve 34 and have the first coupling 33, the first steel pipe connects
Can threaded between 33 with air bleeding valve 34 and steel elbow 32.
It addition, the outlet side of air bleeding valve 34 can arrange the second coupling 35, the second steel pipe connects
Can also be threaded or weld between 35 with air bleeding valve 34.And then joint steel pipe can be by
Steam vent causes place convenient to operate.
Based on the storage tank provided in above-described embodiment, present invention also offers a kind of powder grain material
Transport vehicle, this bulk powder goods tanker includes any one storage tank in above-described embodiment.Due to
This bulk powder goods tanker have employed the storage tank in above-described embodiment, so this powder grain material fortune
