Description

Quartz sand hydraulic separation cleaning device

Technical Field

The invention belongs to the technical field of quartz sand preparation, and particularly relates to a hydraulic sorting and cleaning device for quartz sand.

Background

At present, the domestic production process of the quartz sand mainly comprises the following steps: the method comprises the following steps of mining, crushing, cleaning, drying, sorting and the like, wherein the sorting is generally carried out by adopting a vibration screening machine, a plurality of layers of screening plates are arranged in the vibration screening machine, namely, each layer of screening plate is screened according to the set granularity to obtain quartz sand with different granularities (meshes), but the screening mode has many problems, namely, the granularity of the firstly sorted quartz sand is not uniform, and some fine particles are easy to mix in larger sand grains, so that the granularity distribution of finished sand products cannot reach the standard due to different meshes of the screened standard sand; secondly, during the working process of the vibrating screen machine, a large amount of dust is generated due to the impact between sand grains or between the sand grains and the screen plate, the main component silicon dioxide of the dust has great health threat to human bodies, if the vibrating screen is not tightly sealed, the dust can fly around in a production area, the separated sand grains need to be further cleaned, and finally, due to the fact that the sand grains continuously impact the screen plate of the vibrating screen during the separation process, the durability of the screen plate is reduced, and the screen plate needs to be replaced after being used for a period of time. Therefore, the method of adopting the vibration screening is only suitable for the production of small batches.

In the conventional process flow of the quartz sand, the crushed sand needs to be cleaned and dried before separation, so that the production process is long and is not suitable for enterprises with high quartz sand yield.

Disclosure of Invention

The invention aims to provide a hydraulic quartz sand sorting and cleaning device to meet the requirement of improving the sorting efficiency of quartz sand.

In order to achieve the purpose, the basic scheme of the invention is as follows: a hydraulic sorting and cleaning device for quartz sand comprises a sorting mechanism and a feeding mechanism, wherein the feeding mechanism comprises an overflow box and a feeding box positioned above the overflow box, the upper end and the lower end of the feeding box and the upper end of the overflow box are both arranged in an open manner, and a water inlet is formed in the overflow box; the sorting mechanism comprises a sorting box, the side wall of the sorting box is provided with a sand inlet communicated with the overflow box, and the height of the sand inlet is higher than the bottom of the overflow box; a row of separation cavities are arranged in the separation box in parallel, adjacent separation cavities are separated by a partition plate, the arrangement direction of the separation cavities is parallel to the feeding direction of the sand inlet, a plurality of water supply mechanisms for respectively supplying water to the separation cavities are arranged on the separation box, each water supply mechanism comprises a plurality of water spray holes, and the openings of the water spray holes face upwards; an ultrasonic generator is arranged on at least one sorting cavity.

The theory of operation and the beneficial effect of this basic scheme lie in:

1. lead to into water through the water inlet to the overflow incasement, when quartz sand entered into the overflow incasement through the pay-off case, mix with the water in the overflow incasement and form sand water mixture, receive simultaneously that rivers effect enters into the separation box through advancing the sand mouth. Compare in directly using the conveyer belt to convey the quartz sand to the separation box, utilize rivers effect to carry the quartz sand in this application, can reduce the kinetic energy that the quartz sand enters into the separation box, avoid the initial kinetic energy influence of quartz sand to select separately the effect.

2. The separation intracavity is equipped with water supply mechanism, guarantee that every separation intracavity all fills water before selecting separately, when sand water mixture enters into first separation intracavity from advancing the sand mouth, receive the rivers effect and scatter and open, water supply mechanism continues the water supply simultaneously, because the water spray direction of hole for water spraying surpasss upwards, then the ascending hydraulic action of hole for water spraying spun water to quartz sand, can reduce the settling velocity of quartz sand granule, the sand grain of the biggest granularity overcomes the ascending water force effect of hole for water spraying (the effort of vertical direction) and subsides to the bottom of first separation intracavity, the sand grain of all the remaining granularities gets into the second separation intracavity along with the water flow effect (the effort of horizontal direction) of the sand water mixture of initial entering. Because the sand grains are blocked by the partition plate when turning over the partition plate along with the water flow acting force in the horizontal direction, the flow velocity of the water flow is continuously reduced in the process that the water flow is blocked by continuous turning over, so that the sedimentation rate of the sand grains is continuously increased, the particle size of the quartz sand grains which can overcome the hydraulic action in the vertical direction is gradually reduced in the subsequent separation cavities, the sand grains left in each separation cavity are different in particle size, and the separation is completed.

In the process, the hydraulic action is divided into acting force in the vertical direction and acting force in the horizontal direction, and the self gravity, the buoyancy and the ultrasonic acting force of the sand grains are matched, namely, the sand grains are subjected to 5 acting forces in the sorting cavity, if the scheme is not provided with the acting force in the vertical direction provided by the water supply mechanism, the sand grains are only subjected to the acting force in the horizontal direction, the buoyancy force, the self gravity and the ultrasonic acting force, if the sand grains with the grain size of a are settled in the second sorting cavity close to the sand inlet under the four acting forces, the sand grains with the grain size of a are also subjected to the upward impact force under the action of the water supply mechanism, the sand grains with the grain size of a can be possibly deposited in the third or the four sorting cavities close to the sand inlet, this enables a very fine classification of the quartz sand raw material to obtain sand particles with a higher particle size distribution.

3. The quartz sand is dispersed under the action of water flow in the separation cavity, and the quartz sand is suspended in water and continuously washed upwards by the water supply mechanism, so that the sand grains are cleaned, the steps of cleaning and drying the quartz sand before separation are not needed, the production process flow of the quartz sand is greatly shortened, and the production efficiency of the quartz sand is greatly improved. If sand particles impact on the side wall of the separation cavity, mud powder attached to the sand particles can further fall off in the collision process, and dust cannot fly in water, so that the processing environment is greatly improved. And set up supersonic generator, the ultrasonic wave that supersonic generator produced passes through the rivers effect on quartz sand granule for the adnexed mud powder of quartz sand granule surface drops, because the shape of quartz sand granule is not regular, the mud powder in the less gap only passes through the difficult sanitization of rivers effect, uses the ultrasonic wave to wash, makes the cleanliness factor of quartz sand granule higher.

Further, the water inlet is equipped with a plurality ofly and evenly distributed in overflow tank bottom.

Has the advantages that: the water inlet sets up in the bottom of overflow box, and the water of pouring into through the water inlet is to the ascending effort of quartz sand, avoids quartz sand granule in the overflow box the unable conveying that the end leads to the separation box in.

Further, the side walls of two opposite sides of the feeding box are fixedly provided with buffer plates, and the free ends of the buffer plates are obliquely and downwards arranged.

Has the advantages that: on one hand, when the quartz sand falls into the overflow box, the downward force of the quartz sand is small, the quartz sand sinks in the mixing groove to a small depth, so that the quartz sand is conveniently mixed with a water body and enters the sorting box under the action of water flow; on the other hand, can avoid quartz sand to fall into the overflow incasement fast and make the water in the overflow incasement splash away in a large number for sand water proportion is difficult to control.

Furthermore, the buffer plates on the side walls of the two sides of the feeding box are arranged in a staggered mode, and the projection area of the buffer plates in the vertical direction is larger than one half of the area of the inner cavity of the feeding box.

Has the advantages that: the quartz sand particles can be ensured to impact on the buffer plate layer by layer and slide down along the buffer plate.

Further, water supply mechanism sets up in the separation box bottom, and water supply mechanism includes that the intercommunication has the water spray spare at many delivery pipes of every separation chamber bottom, delivery pipe upper end intercommunication, and the hole for water spraying sets up on the water spray spare, and the delivery pipe is upwards perpendicularly.

Has the advantages that: 1. the water supply pipes are provided with a plurality of water supply pipes and are arranged at the bottom of the separation cavity, and because the water body has flowing dispersibility, if only one water supply pipe is arranged, the impact force of the water flow right above the water supply pipe is the largest, and the impact force is reduced due to the dispersion right above the water supply pipe, the impact force is far away from the water supply pipe, the influence on the sedimentation rate of the sand grains is reduced, and the separation of the sand grains is further influenced;

2. the water supply pipes are vertically upward, and under the condition that the number and the pipe diameters of the water supply pipes are fixed, the occupied area of the plurality of water supply pipes in the horizontal direction is the smallest, and if the water supply pipes are obliquely arranged, the occupied area of the water supply pipes in the horizontal direction is larger, so that the sedimentation of sand grains is easily influenced.

Furthermore, the water spray piece is the water spray disk of fixing in the delivery pipe upper end, and the hole for water spraying is equipped with a plurality ofly and water spray disk along circumference equipartition, and the one end slope that the hole for water spraying kept away from water spray disk axis is upwards.

Has the advantages that: the water spraying disc is arranged, so that the direct falling of sand particles in the sedimentation process into the water supply pipe and the blockage of the water supply pipe can be avoided.

Further, the ultrasonic generator is arranged at the bottom of the sorting cavity close to one side of the sand inlet.

Has the advantages that: since the quartz sand in the separation chamber close to the sand inlet is not cleaned and the amount of mud powder or fine powder attached to the quartz sand is large, the quartz sand is preferably arranged on the separation chamber close to the sand inlet when the number of the ultrasonic generators is limited in view of cost saving.

And a plurality of water spray tray settings are at the diapire of selecting separately the chamber, and the sand grain sinks to block easily between adjacent water spray tray when selecting separately the chamber bottom, is difficult to discharge, sets up supersonic generator in the bottom of selecting separately the chamber, and then the ultrasonic action that the rivers that select separately the chamber bottom received is most obvious, and the vibration of rivers is most obvious, can avoid the sand grain card to a certain extent between adjacent water spray tray.

Further, the upper end parallel and level of many delivery pipes in every separation intracavity, and the water spray disc size is unanimous, and the pipe diameter of many delivery pipes in every separation intracavity is unanimous.

Has the advantages that: under the condition that the water inflow and the water pressure of the water supply pipe are constant, because the water flow acting force at the position closer to the water spray disc is larger, if the water supply pipe in the separation cavity is uneven, the acting force in the water flow direction discharged by each water spray piece is unevenly distributed in the separation cavity, and the separation effect is easily influenced.

For making simple structure, when supplying water, outside water pipe is connected simultaneously to many delivery pipes and supplies water, and when the delivery pipe diameter is different, the delivery pipe that the pipe diameter is thinner is great to the resistance of rivers, therefore rivers flow in to the water pipe that the pipe diameter is thicker easily, leads to the water supply of delivery pipe inhomogeneous, and the homogeneity that consequently supplies water can be guaranteed to the pipe diameter of delivery pipe unanimity.

Further, the baffle is equipped with in the separation box and is used for driving the gliding driving piece of sliding part including fixing fixed part and the vertical sliding connection in the separation box.

Has the advantages that: through the slip of drive sliding part, can change the height of baffle, the height of baffle is higher, and is more obvious to the effect that blocks of horizontal direction rivers, through the height of adjustment baffle, can adjust the water resistance of horizontal direction for the granularity that quartz sand was selected separately is more accurate.

Further, the baffle can be dismantled and connect in the separation box.

Has the advantages that: by disassembling the partition board, the partition boards with different heights can be replaced. Compare the slip mode of baffle, the mode of can dismantling the connection is though it is more troublesome to change, nevertheless need not set up the driving piece, and device overall structure is more simplified.

A plurality of baffles 9 separate sorting box 7 for a plurality of sorting chambers 8, and sorting chambers 8 all are the cuboid form, and sorting chamber 8's bottom center department is equipped with row's sand mouth 10 that can open and close, and is concrete, and sorting box 7 bottom sliding connection has the bottom plate that can shelter from row's sand mouth 10, and sorting chamber 8's bottom all is equipped with the water conservancy diversion portion that is the back taper.

The bottom that lies in every separation chamber 8 on the separation box 7 all is equipped with water supply mechanism, and water supply mechanism includes many perpendicular ascending delivery pipes 11, and all delivery pipes 11's pipe diameter is unanimous. The delivery pipe 11 runs through water conservancy diversion portion and extends to in selecting separately the chamber 8, and many delivery pipes 11 use row sand mouth 10 as the centre of a circle along water conservancy diversion portion circumference equipartition, and many delivery pipes 11's upper end parallel and level.

The upper ends of the water supply pipes 11 are all communicated with water spraying members, and in the embodiment, as shown in fig. 2, the water spraying members are water spraying disks 12 fixed at the upper ends of the water supply pipes 11, and the sizes of the water spraying disks 12 are all consistent. The top of the water spray disk 12 is in an arc shape protruding upwards, i.e. the upper end of the water spray disk 12 is similar to a hemisphere.

An ultrasonic generator is installed on the sorting box 7, the type of the ultrasonic generator in this embodiment is komada/KMD-28, (how to install the ultrasonic generator can refer to the existing ultrasonic cleaning machine, which is not described in this embodiment), specifically, the number of the ultrasonic generator is the same as the number of the sorting cavities 8, that is, the ultrasonic generator (not shown in the figure) is installed on the sorting box 7 corresponding to the side wall of each sorting cavity 8, the frequency of the ultrasonic generator is 28khz-42khz, and the frequency of the ultrasonic generator gradually decreases along the flow direction of the sand-water mixture.

The specific implementation process is as follows:

before selecting separately, lead to into water in 8 to selecting separately the chamber through water supply mechanism, lead to water in 5 to the overflow box through water inlet 6, dry quartz sand drops into the workbin 1 that send, and quartz sand receives the stopping of buffer board 2 when dropping downwards in the workbin 1, and quartz sand's movement potential can most be absorbed by buffer board 2, makes in it enters into overflow box 5 with lower speed, avoids making the water in the overflow box 5 receive the impact of quartz sand to splash away in a large number. Continuously lead to water in to overflow box 5 through water inlet 6, during the surface of water in overflow box 5 and advance sand mouth 13 parallel and level, the hosepipe in overflow box 5 moves quartz sand and enters into separation box 7 through advancing sand mouth 13, because water inlet 6 continuously leads to water in to overflow box 5, and water inlet 6 sets up in overflow box 5 bottom, and rivers are to quartz sand ascending effect, avoid quartz sand to sink the bottom in overflow box 5. Water in the overflow box 5 continuously drives the quartz sand to enter the separation cavity, and the sand-water mixture entering the separation cavity has horizontal force.

When the sand-water mixture enters the first sorting cavity 8 from the sand inlet 13, the sand-water mixture is dispersed by the action of water flow in the sorting cavity 8, meanwhile, the water supply mechanism continuously supplies water, and the water flow sprayed out through the water spraying holes 17 has upward component force, so that the settling velocity of quartz sand particles in the sorting cavity 8 can be reduced. The sand grains with the largest size are settled to the bottom of the first sorting chamber 8 by overcoming the upward water force (vertical force) of the water spray holes 17, and the sand grains with the rest sizes turn over the partition plate 9 to enter the second sorting chamber 8 along with the water flow force (horizontal force) of the sand-water mixture which enters initially. Because the sand grain receives stopping of baffle 9 when the baffle 9 is overturned along with the rivers effort of horizontal direction, rivers are constantly overturning obstructed in-process, and the velocity of flow constantly reduces for the settling rate of sand grain constantly increases, consequently in subsequent separation chamber 8, can overcome the quartz sand granule granularity of the hydraulic action of vertical direction and reduce gradually, make the sand grain granularity that leaves in every separation chamber 8 different, accomplish and select separately.

In the sorting process, the bottom plate can block the sand discharge port 10, and the bottom plate is slid after sorting is finished to discharge sand grains and water in each sorting cavity 8, so that continuous stopping is needed when a large number of sand grains are sorted, and the sorting is troublesome; the sand discharge port 10 can be directly opened, sand particles settled to the bottom of the separation cavity 8 are directly discharged along the surface of the flow guide part, however, more discharged water is arranged, the water also needs to be collected when the sand particles are collected, and the collected water is introduced into the separation cavity 8 again for recycling.

Above-mentioned in-process starts supersonic generator, and the ultrasonic wave that supersonic generator produced passes through rivers and acts on quartz sand granule for quartz sand granule surface adhesion's mud powder drops, because quartz sand granule's shape is irregular, and the mud powder in the less gap only passes through the difficult sanitization of rivers effect, uses the effect of ultrasonic wave cooperation water power to wash, makes quartz sand granule's cleanliness factor higher.

Example 2

The difference between this embodiment and embodiment 1 lies in, the setting of baffle 9 is different, specifically, combine fig. 4 to show, baffle 9 includes fixed part 22 and sliding part 21, fixed part 22 and sliding part 21 all are platelike, fixed part 22 welds in sorting box 7, the vertical sliding connection of sliding part 21 is on the right side of fixed part 22, specifically, all be equipped with the spout on the lateral wall of sorting box 7 front and back both sides, fixed part 22 sliding connection is in the spout, sorting box 7 top is equipped with the gliding driving piece of sliding part 21 that is used for driving, in this embodiment, the cylinder is selected for use to the driving piece (not shown in the figure), the output shaft of cylinder and the upper end of sliding part 21 are fixed. In addition, the driving piece can also adopt a screw rod transmission mode. Compared with embodiment 1, the height adjustment of the partition board 9 is realized by sliding the sliding part 21, and the adjustment can be realized only by manually starting or closing the air cylinder, so that the adjustment is more convenient.

Example 3

The difference between this embodiment and embodiment 1 is that the ultrasonic generators 20 are arranged differently, specifically, as shown in fig. 4, the number of the ultrasonic generators 20 is one half of the number of the sorting chambers 8, and the ultrasonic generators 20 are correspondingly installed at the bottom of half of the sorting chambers 8 near the sand inlet 13, and the frequency of each ultrasonic generator 20 is 33 khz. In the implementation process, the ultrasonic generator 20 is started intermittently, the time interval of each start is 2-4s, and the start time interval of the ultrasonic generator 20 is gradually increased along the flowing direction of the sand-water mixture.

Compared with embodiment 1, in the present embodiment, the frequency of the ultrasonic generators 20 is kept consistent, the number of the ultrasonic generators 20 is reduced, and the ultrasonic generators 20 are intermittently started, so that energy can be saved to a certain extent. The ultrasonic generator 20 is arranged on the sorting chamber 8 close to the sand inlet 13, because the quartz sand in the sorting chamber 8 close to the sand inlet 13 is not cleaned, and more mud powder or fine powder is attached to the quartz sand, when the frequency of the ultrasonic wave is fixed, the starting time interval of the ultrasonic generator 20 is shorter, so that the mud powder on the quartz sand is intensively cleaned, and a better cleaning effect can be obtained.

And intermittently starting the ultrasonic generator 20, has the following effects: when the sand grains are continuously acted by the ultrasonic waves and the water flow, the resultant force of the sand grains with the same granularity in the sorting cavity 8 is constant, after the ultrasonic generator 20 is suddenly closed, the acting force of the sand grains is reduced by one, the original resultant force of the sand grains is broken, the movement track in front of the sand grains is changed to a certain extent, the ultrasonic generator 20 is suddenly opened, the movement track of the sand grains is recovered, in the process, the sand grains vibrate to a certain degree, and the cleaning effect of the sand grains is good.

Meanwhile, in the present embodiment, the ultrasonic generator 20 is installed at the bottom of the sorting chamber 8. Compared with the embodiment 1, the water supply pipes 11 are arranged on the bottom wall of the separation cavity 8, sand is prone to being clamped between the adjacent water supply pipes 11 when settling to the bottom of the separation cavity 8 and is difficult to discharge, the ultrasonic generator 20 is arranged at the bottom of the separation cavity 8, the water flow at the bottom of the separation cavity 8 is most obvious in ultrasonic action, vibration of the water flow is most obvious, and sand can be prevented from being clamped between the adjacent water spraying discs 12 to a certain extent.

Example 4

The difference between this embodiment and embodiment 1 is that the water supply mechanism is arranged differently, specifically, as shown in fig. 5 and fig. 6, the water spray member is a water spray disk 12 rotatably connected to the upper end of the water supply pipe 11, the water spray holes on the same water spray disk 12 are all arranged obliquely along the same direction of the circumference of the water chamber, and the water flow is discharged from each water spray hole 17 through the water chamber 16, and the water spray disk 12 is pushed in the counterclockwise (or clockwise) direction of the water flow, so that the water flow rotates. The bottom of the water spraying disc 12 is provided with a sand cleaning hole, only one sand cleaning hole is arranged for reducing the shunt of the sand cleaning hole in the embodiment, the sand cleaning pipe 23 is bonded at the sand cleaning hole, the sand cleaning pipe 23 is a rubber pipe in the embodiment, and the outlet of the sand cleaning pipe 23 faces the root of the water supply pipe 11.

Because the bottom of each sorting cavity 8 all sets up to the toper that carries out the water conservancy diversion to the sand grain, consequently the sand grain can flow along the bottom of sorting cavity 8 and discharge from sand discharge port 10, and this in-process, some sand grain can be piled up at the root of delivery pipe 11 for this part of sand grain can't be discharged, consequently sets up the sand removal hole in the bottom of water cavity 16, and the sand removal hole is discharged can be followed to some clear water in the water cavity 16 to act on the root of delivery pipe 11, washes away the sand grain of this department. The clear water that follows the sand removal hole through sand removal pipe 23 discharge can directly erode the root of delivery pipe 11 like this, will pile up the sand washing away at delivery pipe 11 root, and the revolution takes place along with water spray tray 12 for sand removal pipe 23 simultaneously, and it is when rotating around delivery pipe 11 for the water below water spray tray 12 produces spiral rivers, further slows down the settling rate of sand grain, makes the granule size sand grain that probably drops here come up along with the rivers, improves the particle size distribution of the back sand grain of sorting.

The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
