Description

Sorting structure of quartz sand sorting device

Technical Field

The invention relates to the technical field of quartz sand sorting, in particular to a sorting structure of a quartz sand sorting device.

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.

However, 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 yield.

Disclosure of Invention

The invention provides a sorting structure of a quartz sand sorting device, which aims to solve the problems of long production process and low efficiency of quartz sand in the prior art.

In order to achieve the purpose, the basic scheme of the invention is as follows:

the utility model provides a quartzy sand sorting unit's separation structure, includes the separation box, separation box one end is equipped with into sand mouth, and the other end is equipped with the sand outlet, the separation box is interior along advancing sand mouth to the vertical baffle that is equipped with the polylith parallel to each other of sand outlet direction, the height of baffle is 1/2 ~ 3/4 of separation box height, the baffle separates into a plurality of circumference closed separation chambeies with the separation box, and each separation chamber bottom all is equipped with the sand discharge mouth, and the bottom in each separation chamber all is equipped with the water filling port, still includes the water supply mechanism of intercommunication water filling port.

The technical principle and the effect of the basic scheme are as follows:

1. the quartz sand after being crushed and water are mixed into a sand-water mixture (or water is added into the quartz sand during crushing) to be fed from the sand inlet by adopting the basic scheme, sand grains in the sand-water mixture flow from the sand inlet to the sand outlet along with the flow of the water body, and meanwhile, the water body is blocked by a plurality of clapboards, so that the flow of the water body containing the sand grains is continuously blocked, the flow speed is continuously reduced, the sedimentation rate of the sand grains in the water body is continuously increased under the condition that the flow speed of the sand grains in the water body is continuously reduced, and the sedimentation speeds of the sand grains with different grain sizes in the water body are different, so that the grain sizes of the sand grains discharged from each separation cavity are different, and the separation effect is achieved; meanwhile, the flow of the water body has a cleaning effect on sand grains, so that the steps of cleaning and drying the quartz sand before separation are not needed by adopting the technical scheme, the production process flow of the quartz sand is greatly shortened, and the production efficiency of the quartz sand is greatly improved.

2. The water flow that water supply mechanism sent into the separation chamber in this basic scheme forms ascending impact force in the separation chamber, and the sand grain receives this impact force, and its settling velocity further reduces, and the advantage that so sets up is illustrated: if the scheme is not provided with the water supply mechanism, the sand grains are only subjected to the force, buoyancy and self gravity of the water flowing to the sand outlet, and if the sand grains with the grain size of a settle in the second sorting cavity close to the sand inlet under the three acting forces, the sand grains with the grain size of a are also subjected to upward impact force under the action of the water supply mechanism, so that the sand grains with the grain size of a can be possibly deposited in the third or the fourth sorting cavities close to the sand inlet, and therefore, quartz sand raw materials can be finely sorted to obtain the sand grains with higher grain size distribution.

Furthermore, the bottom of each sorting cavity is in an inverted cone shape.

Has the advantages that: the sand grains settled to the bottom of the sorting cavity are discharged from the sand outlet along the conical inclined plane, and the bottom of the sorting cavity is arranged to be in an inverted conical shape, so that the flow guide effect on the sorted sand grains is achieved.

Furthermore, the water injection ports are provided with a plurality of water injection ports, and are uniformly distributed at the bottom of the separation cavity along the sand discharge ports.

Has the advantages that: the setting of a plurality of water filling ports for the impact force area of the rivers of following the water filling port injection to the water filling port top water improves, and the reason lies in, because the water has the dispersibility that flows, if the water filling port only sets up one, the impact force of the rivers directly over the water filling port is the biggest, and keeps away from the rivers impact force directly over the water filling port and reduces because of the dispersion, will reduce the sedimentation rate influence of sand grain, and then the influence is to the sorting of sand grain.

Furthermore, a metal pipe positioned in the separation cavity is vertically fixed at the water injection port.

Has the advantages that: since the sorted sand particles are discharged along the conical bottom wall of the sorting chamber, a metal tube is fixed at the water injection opening in order to avoid sedimentation of the sand particles into the water injection opening during this process.

Has the advantages that: because water current need be followed water filling port vertical upwards blowout, the impact force to the sand grain is the biggest like this, but the sand grain of sorting out still subsides downwards simultaneously, for avoiding partly sand grain direct drop in the tubular metal resonator to block up the tubular metal resonator, consequently be equipped with the water spray dish that water current follow lateral wall blowout at its top.

Furthermore, the water spraying disk is rotationally connected with the metal pipe, and all the water spraying holes on the same water spraying disk are obliquely arranged along the same circumferential direction of the water spraying disk.

Has the advantages that: when the clear water is discharged from each water spraying hole through each water cavity, the acting force in the same tangential direction of the water spraying disc is given, so that the water spraying disc rotates when the clear water is sprayed out, and after the water spraying disc rotates, the discharged water flow enables the water body above the water spraying disc to form turbulent flow, the acting forces in multiple directions are formed in the water body above the water spraying disc, and the effects of buffering and cleaning sand grains are further improved.

Further, the top of the water spraying disc is in an arc shape protruding upwards.

Has the advantages that: because sand grain can directly impact the top of the water spray disk in the sedimentation process, and the top of the water spray disk is arranged into an upward convex arc shape, the action areas of the sand grain and the water spray disk can be reduced, and the service life of the water spray disk is prolonged.

Furthermore, the bottom of the water cavity is provided with a sand cleaning hole.

Has the advantages that: because the bottom in each separation chamber all sets up to carry out the toper of water conservancy diversion to the sand grain, consequently the sand grain can flow along the bottom in separation chamber and discharge from the sand discharge port, and this in-process, part sand grain can pile up the root at the tubular metal resonator for this part sand grain can't be discharged, consequently sets up sand cleaning hole in the bottom in water cavity, and the sand cleaning hole discharge can be followed to the partial clear water in the water cavity, thereby is used in the root of tubular metal resonator, washes away the sand grain of this department.

Furthermore, a sand cleaning pipe is fixed at the sand cleaning hole, and an outlet of the sand cleaning pipe faces to the root of the metal pipe.

Has the advantages that: the root of tubular metal resonator can directly be washd to the clear water of following sand removal hole through sand removal pipe discharge like this, will pile up and wash away at the sand grain of tubular metal resonator root, and the revolution takes place along with the water spray tray for the clear water of clear water pipe simultaneously around the tubular metal resonator rotation for the water below the water spray tray produces spiral rivers, further slows down the settling rate of sand grain, makes the granule footpath sand grain that probably drops here come up along with the water flow, improves the particle size distribution of the back sand grain of sorting.

Further, the pipe diameter of the sand cleaning pipe is 3-5 cm, and the sand cleaning pipe is a rubber pipe.

Has the advantages that: in order to avoid the sand cleaning pipe to disperse away too much water flow, thereby reducing the flow of water flow discharged from the water spray holes, limiting the pipe diameter of the sand cleaning pipe within 3-5 cm, and because the sand cleaning pipe can continuously collide with settled sand grains along with the rotation of the water spray disc, the problems of brittle failure and the like are avoided for improving the durability of the sand cleaning pipe, and the rubber pipe is adopted.

The sand-water mixture entering the separation chamber 2 flows from the sand inlet 11 to the sand outlet 12 of the water body containing sand grains, and is sequentially blocked by the plurality of partition plates 14, so that the flow resistance of the water body containing sand grains is increased, the flow velocity of the water body containing sand grains is reduced, the flow velocity reduction amplitude of the water body containing sand grains flowing through each partition plate 14 is sequentially increased from right to left, the sedimentation rate of the sand grains in the separation chamber 2 is increased under the condition that the flow velocity of the sand grains in the water body is reduced, and the separation from the mixture is realized, the farther away from the separation chamber 2 of the sand inlet 11, the smaller the flow velocity in the separation chamber is, the smaller the particle size of the sand grains collected and settled in the separation chamber is, and the finer the sand grains are; in addition, after the water pumps are started, clean water in the water storage tank is sent into the separation cavity 2, upward impact force is formed in the separation cavity 2 by water flow, after sand-water mixture enters the first separation cavity 2, sand grains are subjected to the upward impact force of the water flow, the sedimentation speed is further reduced, more quartz sand with the grain size specification at the separation position is obtained by adjusting the flow speed of each water pump, and meanwhile, the quartz sand is cleaned.
