Abstract
The utility model discloses wet screening equipment applied to hydrophobic fine grained materials, and belongs to the technical field of screening equipment. According to the technical scheme, the wet screening equipment comprises a screening machine and a water tank. The two ends of the water tank are provided with a water supplement pipe and an overflowing weir respectively; the bottom of the water is provided with a screen underflow discharge port; an electric gate valve is arranged on the screen underflow discharge port; a screen of the screening machine is bent to be in the shape of V along a straight-line crease perpendicular to the material conveying direction, the portion, close to the crease, of the screen is located below the liquid level of the water tank, and the portions, close to a feed port and the screen underflow discharge port are located above the liquid level of the water tank. Because the V-type screen placed in the water tank is used for screening the materials, the wet screening equipment wet well solves the problems that when an ordinary screening machine is used for processing hydrophobic materials like quartz sand, because dehydration speed is high, screening and grading can not be efficiently carried out. The wet screening equipment applied to the hydrophobic fine grained materials can effectively improve the hydrophobic fine grained material screening efficiency and has the advantages of being simple in structure, convenient to operate and the like.
Description
Technical field
The utility model relates to a kind of equipment for the hydrophobicity fines such as quartz sand are carried out to the wet sieving classification, belongs to the screening plant technical field.
Background technology
Glass work high-purity SiO used
2The kiln release mesh that enters of quartz sand is 0.1-0.7mm, therefore needs to use vibratory sieve to carry out the classification processing to quartz sand.The sieve classification operation of quartz sand is all wet sieving, and because quartz sand has hydrophobicity, on-the-sieve material is dewatered very soon and formed the siccative layer after ore pulp enters screen(ing) machine, causes screening efficiency to descend and even can't sieve.Therefore how the hydrophobicity fines such as quartz sand are carried out to high efficiency screening and classification just becomes the difficult problem that the relevant technologies personnel face.
The utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of wet sieving equipment that is applicable to the hydrophobicity fine, to improve the screening efficiency of this type of material.
Problem described in the utility model realizes with following technical proposals:
A kind of wet sieving equipment that is applicable to the hydrophobicity fine, formation comprises screen(ing) machine and tank, the two ends of described tank are respectively arranged with filling pipe and downflow weir, and its bottom is provided with the screenings discharge gate, is provided with the electric brake plate valve on described screenings discharge gate; The screen cloth of described screen(ing) machine is converted into V-type along the straight line folding line perpendicular to the mass transport direction, and its position near folding line is positioned under the liquid level of tank, and the position of close material inlet and oversize discharge gate is positioned on the liquid level of tank.
The above-mentioned wet sieving equipment that is applicable to the hydrophobicity fine, the inner side of described tank is provided with liquid level gauge, and the bottom of tank is provided with pressure sensor, and the signal output part of liquid level gauge and pressure sensor connects the controller of screening plant.
The above-mentioned wet sieving equipment that is applicable to the hydrophobicity fine, be provided with electrically operated valve on described filling pipe.
The V-type screen cloth that the utility model utilization is placed in tank sieves material, solved well when the hydrophobicity materials such as quartz sand are processed with common screen(ing) machine because of dewatering speed soon can't high efficiency screening, the difficult problem of classification.The utility model not only can effectively improve the screening efficiency of hydrophobicity fine, but also has the advantages such as simple in structure, easy to operate.
The accompanying drawing explanation
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
In figure, each label is: 1, tank, 2, downflow weir, 3, the oversize discharge gate, 4, screen cloth, 5, normal liquid level, 6, liquid level gauge, 7, V font waters, 8, material inlet, 9, filling pipe, 10, electrically operated valve, 11, pressure sensor, 12, electric brake plate valve, 13, the screenings discharge gate, 14, screenings precipitation accumulation regions.
The specific embodiment
Referring to Fig. 1, the utility model mainly consists of screen(ing) machine and tank 1, the interior installation liquid level gauge 6 of tank 1, and tank 1 top arranges the filling pipe 9 that electrically operated valve 10 is housed, and tank 1 upper limb is established downflow weir 2, and overflow water is discharged by downflow weir 2.The interior pressure sensor 11 that arranges of screenings precipitation accumulation regions 14 in tank, the screenings discharge gate 13 of electric brake plate valve 12 is equipped with in the bottom of gullet setting.
The screen cloth 4 of screen(ing) machine is arranged in tank 1, during screen(ing) machine work, screen cloth 4 is in the straight-line oscillation state under the vibrating motor effect, and direction of vibration and screen cloth 4 form certain projection angles, the turnover position of screen cloth 4 is in underwater, the screen cloth top forms a V font waters 7, during work, material is injected into the feeding end of screen cloth 4 continuously from material inlet 8, on-the-sieve material is effectively sieved by the screen cloth 4 that immerses V font waters 7, classification, oversize is under the conveying effect of screen cloth, to the discharge end direction, creep to more than liquid level gradually, finally through oversize discharge gate 3, discharge, screenings is assembled to 14 sedimentations of bottom of gullet precipitation accumulation regions gradually under the self gravitation effect, when the screenings pressure that screenings precipitation accumulation regions 14 detected when the pressure sensor 11 that is arranged on bottom of gullet reaches setting value, mean that namely screenings precipitates accumulation regions 14 and assembled the screenings of some, pressure sensor 11 sends signal to controller, controller opens electric brake plate valve 12, the screenings that screenings precipitation accumulation regions 14 is assembled is discharged through the screenings discharge gate 13 of tank 1 bottom.When pressure sensor 11 detects pressure and recovers normal, send signal at stop electric brake plate valve 12, suspend discharge.So periodic cycle, reach dynamic equilibrium, to guarantee the screening plant continuous operation.
Instantaneous in tank goes out the uneven stability that can affect the normal liquid level 5 of the above V font of screen cloth 4 waters 7 liquid level of pan feeding, therefore liquid level gauge 6 is installed in tank, when liquid level gauge 6 detects liquid level and drops to preset lower limit, send the electrically operated valve 10 of unblanking filling pipe 9 to the interior moisturizing of tank 1.When liquid level rises to the capping value near downflow weir 2, send the electrically operated valve 10 of signal at stop filling pipe 9, suspend to the interior moisturizing of tank 1, when the interior liquid level of tank 1 surpassed downflow weir, overflow water was discharged through the downflow weir 2 of tank 1 upper limb.To keep the liquid surface level in tank 1 relatively stable.Overflow water iterative cycles after reclaiming is used.
