Abstract
The invention relates to a differential-type abrasive supply device, which comprises a sand storage tank and an abrasive tank, wherein the sand storage tank is provided with a feed inlet; the abrasive tank comprises a tank body and an upper cover; the tank body and the upper cover are hermetically connected by threads; an O-shaped seal ring is arranged at the top of the tank body; a sand feed inlet and a drain outlet are formed in the upper cover; a relief valve and a seal valve are sequentially arranged on the drain outlet at the direction far away from the abrasive tank; two ends of the sand storage tank are respectively connected with a gas pressure source and the sand feed inlet; a check valve is arranged between the sand storage tank and the sand feed inlet. The differential-type abrasive supply device has the beneficial effects of being capable of supplying abrasive pneumatically for the abrasive tank, saving time and effort, and convenient and fast to control.
Description
Technical field
The present invention relates to abradant jet technical field, especially relate to a kind of differential abradant feeding apparatus.
Background technology
Abradant jet technology is the new technique that RECENT DEVELOPMENTS is got up, in industrial cutting, rock out, surface clean and probing
The aspects such as exploitation are widely used, and according to the difference of abrasive material feed postition, abrasive water-jet is divided into front mixing abrasive water jet
With rear compound abrasive water jet.Because rear compound abrasive water jet can not make abrasive material sufficiently be mixed with swiftly flowing water
Close it will be apparent that reducing the energy transmission efficiency for abrasive material for the aqueous medium, in the case of identical power consumption, rear compound abrasive water-jet
The depth of cut of stream can only achieve the half of front mixing abrasive water jet depth of cut, and in sides such as rock out, probing exploitations
Face, the additional engineering-environment of rock breaking capacity difference due to rear mixed abrasive water-jet limits it is impossible to mix water jet using rear.Cause
This, front mixing abrasive water jet research is particularly important, but front mixing abrasive water jet has the difficult difficult problem of feeding abrasive material, liquid
The bad control of mixed proportion of body and abrasive material, some devices can control the output of abrasive material, but most structure all compares again
Miscellaneous, and effect is not fine.In addition, the feeding abrasive material in front mixing abrasive jet system is at this stage mostly to add sand manually
Mode is realized, and wastes time and energy.
Content of the invention
It is an object of the invention to provide a kind of differential abradant feeding apparatus, above-mentioned with overcome currently available technology to exist
Not enough.
The purpose of the present invention is to be achieved through the following technical solutions：
A kind of differential abradant feeding apparatus, including sand tank and abrasive can, described sand tank is provided with charging aperture；Described
Abrasive can includes tank body and Shang Gai；Described tank body is connected by thread seal with upper lid；Described tank body top is provided with O-shaped sealing
Circle；Described upper lid is provided with plus sand mouth and discharge outlet；Described discharge outlet is disposed with relief valve on away from abrasive can direction
With airtight valve one；Described sand tank two ends connect gas pressure source and plus sand mouth respectively；Described sand tank and plus sand mouth between set
It is equipped with stop valve.
Further, described plus sand mouth is provided with airtight valve two.
Further, described sand tank bottom is provided with sand position meter.
Further, described sand tank is provided with relief valve.
Further, it is provided with air throttle between described sand tank and gas pressure source.
Further, it is provided with pressure gauge between described sand tank and air throttle.
Further, described discharge outlet is more than plus depth in tank body for the sand mouth in the depth in tank body.
Beneficial effects of the present invention are：Can realize pneumatic to abrasive can supply abrasive material, time saving and energy saving, control convenient.

Specific embodiment
As shown in Figure 1-2, a kind of differential abradant feeding apparatus of the embodiment of the present invention, including sand tank 4 and abrasive can
8；Described sand tank 4 is provided with charging aperture and relief valve 5；Described sand tank 4 bottom is additionally provided with sand position meter 6；Described abrasive can 8
Including tank body 81 and upper lid 83；Described tank body 81 is connected by thread seal with upper lid 83；Described tank body 81 top is provided with O-shaped
Sealing ring 82；Described upper lid 83 is provided with plus sand mouth 84 and discharge outlet 85；Described discharge outlet 85 on away from abrasive can 8 direction according to
Secondary be provided with relief valve and airtight valve one, supply abrasive material before open relief valve by abrasive can 8 high pressure discharge；Described draining
Mouth 85 depth in tank body 81 is more than plus sand mouth 84 depth in tank body 81；Described plus sand mouth 84 is provided with airtight valve two.
The feeding abrasive material method of above-mentioned differential abradant feeding apparatus：Abrasive sand will be filled in sand tank 4, close sand tank
4 charging apertures, open gas pressure source 1, drive the abrasive material in sand tank 4 to flow in abrasive can 8, thus realizing using gas pressure
Feeding abrasive material function.
During feeding abrasive material, there is abrasive material to flow out together with water at discharge outlet 85, illustrate that in abrasive can 8, abrasive material has filled
Full, now close stop valve 7 and stop supply abrasive material；Simultaneously close off and add airtight valve at sand mouth 84 and discharge outlet 85, make abrasive can 8 close
Envelope.
When in sand tank 4, abrasive sand position is less than sand position meter 6, sand position meter 6 sends alarm signal.Safety on sand tank 4
Valve 5, can effectively prevent internal system superpressure, improve security of system.
By adjusting air throttle 2 with adjusting gas flow thus realizing the flow-control of feeding abrasive material.
The present invention is not limited to above-mentioned preferred forms, and anyone can show that under the enlightenment of the present invention other are various
The method of form, however, make any change at it in form, every have technical scheme identical or similar to the present application,
It is within the scope of the present invention.
