Description

Sand-stone separator

Technical Field

The utility model relates to a grit separation technical field, more specifically say, it relates to a grit separator.

Background

A sand-stone separator is composed of feeding channel, stirring separator and water supply unit, and features that the cement slurry flows from the slurry outlet at bottom of separator and through slurry guiding channel to slurry pool, the cleaned sand and stone are driven by spiral blades in stirring separator, the separated sand and stone fall into slurry pool via their discharge ports, the cement slurry flowing from slurry pool is mixed with clean water by superposition method, and the mixture of sand, stone and slurry is reused.

To current grit separator, chinese patent for CN206578006U if the grant bulletin number, it discloses a sand and stone separator, its technical scheme main points include the frame, driving piece and screen cloth section of thick bamboo, the driving piece is connected with the screen cloth section of thick bamboo, drive the rotation of screen cloth section of thick bamboo, be connected with the pivot on the driving piece, be provided with the cover on the screen cloth section of thick bamboo and locate the epaxial axle sleeve of pivot, be provided with the elastic layer between axle sleeve and the pivot, the both ends of screen cloth section of thick bamboo are fixed with the butt piece, be fixed with in the frame and block the dog on butt piece circumferencial path, still include into hopper and stone outlet, the slope of screen cloth section of thick bamboo sets up, it connects in the high-end of screen cloth section of thick bamboo to.

When above-mentioned sand and stone separator used, the grit mixture directly got into a screen cloth section of thick bamboo through going into the hopper, because great stone gets into easy card in a screen cloth section of thick bamboo in the grit separator, causes the damage to equipment, causes the hindrance to the grit mixture simultaneously for the grit mixture is difficult to enter into and carries out separation work in the grit separator, reduces grit separation efficiency.

SUMMERY OF THE UTILITY MODEL

The problem of the great stone can not be sieved to the feeder hopper that prior art exists, the utility model aims at providing a sand and stone separator, it has the advantage that the great stone can be sieved to the feeder hopper.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a sand and stone separator, includes the frame and sets up a screen cloth section of thick bamboo in the frame, screen cloth section of thick bamboo one end is provided with the feeder hopper, can dismantle in the feeder hopper and be provided with the screen cloth groove.

Through the technical scheme, in practical application, when workers put the sand-stone mixture into the feed hopper, the sand-stone mixture is firstly screened out through the multilayer screen mesh grooves, and stones with the diameter larger than the screen mesh diameter of the screen mesh grooves are screened out, so that the stones cannot enter the screen mesh cylinder, and the larger stones are prevented from entering the sand-stone separator and being clamped in the screen mesh cylinder to damage equipment; the activity of screen cloth groove sets up in the feeder hopper, and when the stone accumulation in the screen cloth groove was more, the staff took out the screen cloth groove from the feeder hopper and collected great stone, put back the feeder hopper with the screen cloth groove again, continued the separation work.

Further, the one end of feeder hopper is close to the frame, the sieve mesh groove is provided with the multilayer, the multilayer sieve mesh edge in sieve mesh groove the direction of height of feeder hopper is close to towards the feeder hopper the one end of frame reduces gradually.

Through above-mentioned technical scheme, in the in-service use, the sieve mesh size that is located on the screen cloth groove of below is less than the sieve mesh size that is located on the screen cloth groove of top, consequently when carrying out the separation work, the great grit of size is separated by the screen cloth groove that is located the top, and the grit that the size is less is separated by the screen cloth groove that is located the below, and the grit mixture falls into a screen cloth section of thick bamboo, has improved the efficiency of grit separation work.

Furthermore, the feed hopper is fixed with the spacing strip that is used for restricting the screen cloth groove.

Through above-mentioned technical scheme, in the in-service use, the position of multilayer screen cloth groove is restricted to spacing, makes it can not produce the condition of sinking under the action of gravity of more stone at the screening in-process.

Furthermore, a rubber pad is fixed on one side of the limiting strip, which is far away from the rack.

Through above-mentioned technical scheme, in the in-service use, the rubber pad is kept away from one side butt screen cloth groove of spacing, and the rubber pad is used for buffering the impulsive force of great stone to the screen cloth groove, and it is impaired to reduce the screen cloth groove, prolongs the life in screen cloth groove.

Furthermore, a handle is fixed on one side of the screen groove close to the opening end of the screen groove.

Through above-mentioned technical scheme, in the in-service use, when the stone in the screen cloth groove was too much, the staff took out the screen cloth groove through the handle, collected great stone, put back the screen cloth groove in the feeder hopper again, continued the separation work.

Furthermore, one side of the lifting handle, which is far away from the screen groove, is abutted to the screen groove of the upper layer.

Through above-mentioned technical scheme, in the in-service use, one side butt that the screen cloth groove was kept away from to the handle connects the screen cloth groove of one deck, plays the effect of support to the screen cloth groove of one deck for the middle part in screen cloth groove of one deck can not produce the phenomenon of sinking because of the action of gravity of stone.

With the slope setting of a screen cloth section of thick bamboo, the grit mixture enters into a screen cloth section of thick bamboo from high-end after, under the action of gravity, the remaining stone after the filtration can directly flow out from the low side for the ejection of compact speed of stone.

Furthermore, a screen mesh cylinder is obliquely arranged, the feed hopper is connected to the high end of the screen mesh cylinder, and the low end of the screen mesh cylinder is connected with a stone outlet.

Through above-mentioned technical scheme, with the slope setting of screen cloth section of thick bamboo, the grit mixture enters into screen cloth section of thick bamboo from high-end after, under the action of gravity, filters the remaining stone in back and can directly flow out from the low side for the ejection of compact speed of stone.

Furthermore, a conveyor belt is obliquely arranged between the screen drum and the rack, a sand outlet is formed in the high end of the conveyor belt, and a blocking brush is arranged at the low end of the conveyor belt.

Through the technical scheme, the sand outlet is arranged at the upper end of the conveyor belt, so that the discharging directions of the sand and the stones are opposite; and set up on the conveyer belt and keep off the brush, keep off the brush and have certain barrier action to grit, can prevent that the grit from because the action of gravity is landing downwards.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) through the arrangement of the screen groove, larger stones are screened out, the larger stones in the sand-stone mixture entering the screen cylinder are reduced, the normal work of the screen cylinder is ensured, and the sand-stone separation efficiency is improved;

(2) furthermore, the position of the screen groove is limited through the limiting strips and the handles on the next layer of screen groove, so that the screen groove is prevented from sinking under the action of the gravity of more large stones;

(3) furthermore, the baffle plate prevents the sand and stone mixture in the screen cylinder from flying out to hurt workers, and the protection plate protects the driving piece from being hit by stones flowing out of the lower end of the screen cylinder;

(4) further, the sand and the stones are discharged in opposite directions through the conveyor belt, and the blocking brush blocks the sand from sliding downwards.
