Description

A kind of Sand screen
Technical field
The utility model relates to building material manufacture field, particularly a kind of Sand screen.
Background technology
Sand is one of most important raw material in building industry, when using sand, wish that the size of sand is unified, but the sand that the sand pulled out from river or alternate manner are exploited out, not of uniform size, but also mixing the gravel of different size, this just needs screening, the general screening process using sand sieving machine to complete sand.
Disclosure of the invention number: CN201110187495.X discloses a kind of full-automatic sand screening machine, is provided with frame, and frame is provided with feed mechanism, sand sieving machine structure and conveying mechanism.Such sand sieving machine structure, needs vibration sand, and the mobile space of the grains of sand is very little, to the sand having water, can occur sieving motionless clear condition because of caking.
Disclosure of the invention number: CN201210426819.5 discloses a kind of automatic discharge sand sieving machine, comprises screen drum, axle sleeve, support, motor, support and chassis, and support is vertically arranged on chassis, and axle sleeve is installed on top; Support is vertically arranged on chassis opposite side, at support top mounted motor, between motor and axle sleeve, is provided with screen drum, and described screen drum is truncated cone-shaped screen tube body structure, and large round mouth is connected in axle sleeve, little nose circle and machine shaft affixed, and little nose circle is lower than large nose circle; In the little round mouth section of screen drum and the least significant end symmetry of protective cover offer discharging opening.It is husky that mode like this by rolling realizes sieve, and the energy of consumption is comparatively large, and can't resolve grains of sand water content large time, the grains of sand can be tied also block, are unfavorable for the phenomenon of sub-sieve.
In a word, existing sand sieving machine, the motion of all grains of sand, power all comes from the promotion of motor, and the reciprocating motion of the grains of sand, needs more kinetic energy, also just needs powerful motor.
Summary of the invention
The purpose of this utility model be overcome prior art above-mentioned deficiency and a kind of Sand screen is provided, it completes the husky process of sieve by mode that the grains of sand are scattered through husky net.
The technical solution of the utility model is: a kind of sieve method for determining sand, comprise following process, the grains of sand are sent on the rotary blade of rotation, by the quick rotation of rotary blade, the grains of sand are scatter under the influence of centrifugal force, the grains of sand scattered encounter peripheral screen cloth, complete the separation process of the grains of sand and gravel.
The one side that rotary blade contacts with the grains of sand is elastomeric material.As rubber.Such one is the impeller that protection steel disc is made; two is after the grains of sand fall up; bounced again; rotation status is entered under the drive of oblique blade; and fly out under the influence of centrifugal force and fall on screen cloth; driving bounces is positioned at aerial grains of sand speed ratio and drives the grains of sand be attached on impeller to enter rotation status kinetic energy used will to reduce a lot, because it does not need the obstruction of overcome friction again.
The technical solution of the utility model is: a kind of Sand screen, comprises filtration fraction and drive part.
Described filtration part comprises: screen cloth, grains of sand entrance, gravel outlet, bearing support, the top of bearing support is garden barrel shape, and bottom is taper, and screen cloth is fixedly attached on bearing support, grains of sand entrance position enters the upper end of bearing support, and gravel outlet is positioned at the lower end of bearing support.
Described drive part comprises: motor, impeller, blade, motor fixing frame, and motor is fixed on motor fixing frame, and impeller is arranged on the upper end of motor, and blade is fixed on impeller.Impeller upward.
Drive part is arranged on filtration fraction inside, and impeller is positioned at immediately below grains of sand entrance.
The further technical scheme of the utility model is: motor fixing frame is fixed on the middle part of bearing support.Also the bottom of bearing support can be fixed on.
The utility model further technical scheme is: the first support, the second support are arranged at the top of filtration fraction, first support is toroidal, first support of toroidal is welded with the second support, and the inner of the second support is welded with grains of sand entrance, and there is blade the below of grains of sand entrance.
The utility model further technical scheme is: grains of sand entrance can also make drum, also can add a funnel shaped outside again on top, hold together sandstone to facilitate collection.
The utility model further technical scheme is: the 3rd support, the 4th support are arranged at the bottom of filtration fraction, 3rd support is toroidal, 3rd support of toroidal is welded with the 4th support, the lower end of the 4th support is welded with gravel outlet, 3rd support, the 4th support form six trapezoidal lattice, and screen cloth can be divided into that many fritters are arranged on the 3rd support respectively, the 4th support forms in six trapezoidal lattice.When needs overhaul, these six pieces of screen clothes can be taken off respectively, and people just can enter in filtration fraction and remove or mounted motor.
The utility model further technical scheme is: when needs time, also can install the grains of sand in the periphery of this Sand screen and concentrate plate, like this grains of sand sifted out be put together, or transport direct entrucking further by automated process.
The utility model further technical scheme is: when needs time, also former husky conveyer belt and gravel conveyer belt can be installed above this Sand screen, the husky end that falls of former husky conveyer belt aims at grains of sand entrance, gravel conveyer belt is arranged on the lower end of gravel outlet, and the gravel selected sends out by gravel conveyer belt.
The utility model compared with prior art has following features: the utility model fundamentally changes and sieves husky viewpoint, effective, existing sieve method for determining sand, and be all that screen cloth rotates or vibration realizes sieve sand, two is that motor is not arranged on screen cloth inside.What people worried has two problems, one be a large amount of grains of sand descending time, drop on impeller, can produce very large impulsive force to the motor shaft connecting impeller, damage motor, surprising is, this impulsive force is also not very big, because work as motor when rotated, this impulsive force is converted to centrifugal force.Two is that water can or can not flow in motor, causes short circuit phenomenon when the grains of sand have water, and in fact, this is worried and also need not produce.Because when motor rotates, water also can be pulled away with the grains of sand, can not flow in motor completely.
The grains of sand separately disperse to surrounding, completely avoid water and the grains of sand are concentrated at phenomenon together, greatly save kinetic energy, the husky ability of same sieve, and existing motor is 18.5 kilowatts, and the motor that this device uses is 1.5 kilowatts and just can realizes completely.The husky ability of same sieve, the steel weight manufactured required for this device is 1/3rd of prior art, and reason is the structure of this device, eliminates a large amount of supporting parts and drive disk assembly.The screen cloth of this device is changed than being easier to, and can change the screen cloth in the hole of different size easily, thus obtain the grains of sand of different size.
By the sand that this sand sieving machine sifts out, can also according to the further classification of the size of sand because the grains of sand from screen cloth out after, can fly a turn-off from, the large grains of sand can fly farther.Use sand sieving machine of the present utility model, gravel can be made to complete with the grains of sand and separate, sorting is more thorough.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
