Plate carries out processing of rust removing, alleviates the intensity of derusting operation, reduces the dependence to manual labor, also improves construction effect
Rate.
The sand flushing device includes vaccum suction pipe 1, air inlet pipe 2, inhales sand tube 3, dust cover 8,5 sum aggregate sand conduit of silt box
11。
Vaccum suction pipe 1 includes vacuum tubings 13, and one end of the vacuum tubings 13 is equipped with air inlet 14, the other end is equipped with
Sand mouth 15.
It is provided with solar term mouth 17 in the tube body of 13 air inlet section of vacuum tubings, for limiting overflowing end face, improves air inlet
Flow velocity, to form a vacuum chamber in 17 rear end of solar term mouth rapidly.In the present embodiment, the inner section of the solar term mouth 17 is frustum
The inner cavity chamber of shape, solar term mouth 17 is gradually reduced along airintake direction.
The middle part of the vacuum tubings 13 is oblique to be arranged with sand-feeding tube 16, and sand-feeding tube 16 is connected with vacuum tubings 13.
Due to the metallic grit that sand washing uses, relative to water or dust, individual is larger, and in irregular shape, in order to reduce sand grains with
The collision of tube wall reduces the kinetic energy rejection of sand grains, improves sand washing effect, avoids suction pipe blocking, sand-feeding tube is in tilted layout,
In the present embodiment, angle formed by the air inlet section of sand-feeding tube 16 and vacuum tubings 13 is 30 ° -45 °.
The air inlet of vaccum suction pipe 1 is connected with air inlet pipe 2, sand export 15 is arranged in dust cover 8, sand-feeding tube 16 and inhales
Sandpipe 3 is connected.
According to bernoulli principle, the conservation of mechanical energy of fluid, it may be assumed that kinetic energy+gravitional force+pressure potential=constant.Therefore,
In contour flowing, flow velocity is big, and pressure is with regard to small.And according to Venturi effect, in restricted flow, by reducing flow section,
There is the phenomenon that flow velocity increase in fluid, and flow velocity and flow section are inversely proportional.Therefore, the vacuum of the application is used in sand flushing device
After suction pipe 1, after the air inlet 14 of vaccum suction pipe 1 is passed through compressed air, compressed air passes through the solar term mouth inside vaccum suction pipe
17, overflowing end face is reduced, and induction air flow ratio is further increased, and forms a vacuum chamber in the rear side of solar term mouth 17, therefore,
After the sand-feeding tube 16 of vaccum suction pipe 1 connects sand suction pipe 3, it may be implemented to inhale sand function.
The other end of the sand suction pipe 3 is inserted in silt box 5, the silt box 5 be top be equipped with ventilative web plate 4 it is interior in
Empty body structure, the lower section of ventilative web plate 4 are provided with isolation sponge 12.The silt box 5 passes through collection sand conduit 11 and dust cover 8
It is connected, when leading sand, sand dust is flown upward in order to prevent, can coat one layer of dustproof sponge, the present embodiment in the outside of collection sand conduit 11
In, dustproof sponge with a thickness of 3mm-5mm, the dustproof sponge of the thickness while dust-proof, also can guarantee collection sand conduit it is saturating
Gas.
The dust cover 8 covers on hull plate 7, mountable sponge between dust cover 8 and the contact surface of hull plate 7
The gas permeability of press strip 10, sponge press strip 10 is good compared with rubber material, and can play dust-proof effect, when the punching of sand washing tube head 9 is taken out of largely
When sand ball and air-flow, dust cover can be effectively compressed, the sand dust reduced in dust cover 8 is diffused into atmosphere.
Collecting sand conduit 11 is the cylindrical conduit being made using web plate, or using the steel plate production with several through-holes
Made of cylindrical conduit.
The sand washing method in outfield peculiar to vessel of the application, specifically includes the following steps:
Step 1: silt box 5 being placed on the mobile apparatus, hydraulic car or mobile open frame can be used in mobile device.
Step 2: dust cover 8 is covered on hull plate 7 and (dust cover is manually pressed in hull plate by staff
On), sponge press strip 10 is installed between dust cover 8 and the contact surface of hull plate 7.Collection is installed between dust cover 8 and silt box 5
Sand conduit 11, one end of the collection sand conduit 11 is connected with dust cover 8, the other end is connected with silt box 5.
Step 3: the sand export 15 of vaccum suction pipe 1 being connected with the sand washing tube head 9 on the side wall of dust cover 8, in vacuum
The air inlet 14 of suction pipe installs air inlet pipe 2, sand-feeding tube 16 installs sand suction pipe 3, and the other end of sand suction pipe 3 is inserted in silt box 5.For
Guarantee to inhale the pressure difference of sand, in the present embodiment, of length no more than 2m of sand suction pipe 3.
Step 4: compressed air is passed through into air inlet pipe 2, the sand grains in silt box 5 enters vaccum suction pipe 1 from rubber pipe is inhaled,
And sand washing tube head 9 is entered from the sand export of vaccum suction pipe 15, it is ejected from sand washing tube head 9 and strikes 7 surface of hull plate, clearly
The attachment on 7 surface of hull plate is removed, sand grains is recovered in silt box 5 by collecting sand conduit 11.In this way when sand washing derusts,
Can one side sand washing, on one side carry out sand grains recycling, improve the continuity of entire work progress, thus reach reduce operation it is strong
Degree, the purpose for improving production efficiency；And since entire sand flushing device is placed on hydraulic car or mobile open frame, with work when sand washing
The variation of people's operating location can arbitrarily move sand flushing device, get rid of the constraint of fixed construction area, improve sand flushing device
Portability.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent substitution, improvement and etc. done be should be included within the scope of the present invention.
