Abstract

The utility model discloses an efficient dust removing sand sieving machine for artificially sieving the sand and is mainly composed of a sieve body, a sieve body rack, a machine rack, a ventilation dust removing apparatus, a sand collecting device, a powder dust collecting device, etc. The sand material passes through the big hole woven sieve and the main sieve body of the upper end of the sieve body to cause the sand material over the standard to trickle out from both sides of the sieve body. The sand conforming to the standard slides on the main sieve body downwards, and the sand and the powder dust are separated depending on the impact, the friction, the vibration and the rolling process in the downward sliding process. When the sand slides downwards to the position of the lower end port of the main sieve body, the residual powder dust is deposited in a dust removing device by the ventilation dust removing apparatus to be discharged in the definite time or to be discharged along the port of a wind leading machine. The efficient dust removing sand sieving machine has the characteristics of high efficiency, energy saving, high sieving quality, few wasted resources, long service life and little environmental pollution.

Description

High-effective dust-removing screening sandstone machine

The utility model relates to a kind of sandstone screening machine.

At present, the dynamic screening type of sandstone screening installation kind (electronic, machine power), gravity flow screening and artificial screening, the screening that these several screening plants are widely used in mine rubble production line manual sandstone separates, but because equipment is the single-deck screen sheet, the certain impulse force of sandstone power generation dashes qualified manual sandstone own and sifts out by sieve aperture, make the manual sandstone that contains 15-20% in the screened degree material of going out, and this device does not have ventilating dust-arrester, contain many dust in the manual sandstone that screens, and serious environment pollution.

The purpose of this utility model is to provide a kind of screening sandstone machine, is mainly used in cleaning of mine manual sandstone, produces the high-quality manual sandstone that is fit to national project construction needs, reduces the air pollution and the wasting of resources.

The utility model high-effective dust-removing screening sandstone machine is made up of sieve nest, screen frame, frame, ventilating dust-arrester, sandstone gatherer and dust collection etc., sieve nest is made up of macropore wire gauze sieve and main sieve nest, the macropore wire gauze sieve is arranged on the front end of sieve nest and on main sieve nest, main sieve nest is installed on the screen frame, main sieve nest is made up of two-layer or three layers or four layers of descending sieve aperture wire gauze sieve, two ends are the sieve frame, between the sieve frame crossbeam and sieve nest pitch adjustment mechanism are set; Whole sieve nest is mounted obliquely within on the frame; Ventilating dust-arrester is made up of wind sucting chamber, air-suction channel, deduster, air pipeline and air-introduced machine, and wind sucting chamber's opening is arranged on main sieve nest lower port place, and the air draught road communicates with deduster, and deduster communicates with air-introduced machine by air pipeline; Sandstone gatherer and dust collection are mounted on the following frame of sieve nest.

The utility model utilizes the gravity of sandstone and inertia to realize the gravity flow screening, thereby has saved the energy; Unpowered transmission has reduced mechanical failure, has prolonged mechanical service life, correspondingly the wasting of resources is reduced to minimum level simultaneously, and this novel employing multilayer compass screen surface and sieve nest gradient guiding mechanism have solved the industry difficult problem that moist sand material mixture separates well; Ventilating dust-arrester is set, makes that dust content reduces greatly in the manual sandstone, make operating environment eliminate dust pollution substantially simultaneously.

The utility model is described in further detail below in conjunction with accompanying drawing;

The front view of Fig. 1 the utility model high-effective dust-removing sandstone screening machine;

Fig. 2 is the utility model sieve nest and dust removal part partial top view;

Fig. 3 and Fig. 4 are the front view and the vertical views of the utility model sieve nest;

Fig. 5 and Fig. 6 are the front view and the vertical views of the utility model screen frame (unit).

As shown in the figure, high-effective dust-removing screening sandstone machine, by sieve nest 1, screen frame 2, frame 3, ventilating and purifying air system, compositions such as sandstone gatherer 5 and dust collection 6, sieve nest divides main sieve nest 9 and macropore wire gauze sieve 7, main sieve nest is installed on the screen frame (unit) 2, the effect that the macropore wire gauze sieve dusting building stones dispersion of main sieve nest front end separates with the ultra-specification material, main sieve nest is made up of two-layer or three layers or four layers of descending sieve aperture wire gauze sieve, two ends are sieve frame 8, between the two sieve frames crossbeam 10 and sieve nest pitch adjustment mechanism 11 are installed respectively, governor motion is by screen frame 2, side bar 12 and adjustable plate 13 are formed, in order to regulate the angle of inclination of main sieve nest, to separate the manual sandstone of different size.Ventilating dust-arrester is made up of wind sucting chamber 15, air draught road 16, deduster 17, air pipeline 18, air-introduced machine 19 and motor 20, and wind sucting chamber 15 is installed in main sieve nest lower port place, and the air draught road communicates with deduster, and deduster communicates with air-introduced machine by air pipeline; Motor is by motor frame 14 supporting, and the motor frame is installed on the side bar 12, sandstone gatherer 5 and dust collection 6 are mounted on the following frame of sieve nest,

This screening sandstone machine is based on the gravity flow screening, dust removal by ventilation be assist comprehensively clean machinery, the sandstone material is delivered to by the place conveyer on the macropore wire gauze sieve of the superiors of sieve nest upper end, make the sandstone material disperse to separate with the ultra-specification material, the ultra-specification sandstone of bulk drops down from the sieve nest both sides through the separating plate guiding, manual sandstone and dust then drain on the ground floor wire gauze sieve of main sieve nest fast, manual sandstone is in rolling process voluntarily, through clashing into, rub, vibrate and roll and screening layer by layer, dust is separated with sandstone, and dust falls into dust collection; And the sandstone above each layer wire gauze sieve slides to main sieve nest lower port when the wind sucting chamber, the dust that contains in the manual sandstone is sucked in the deduster by wind, and under the effect of deduster, a large amount of dust deposits are in deduster, regularly enter, the minute quantity dust enters air-introduced machine through air pipeline and discharges.In wind sucting chamber, fall into the sandstone gatherer from the end opening of wind sucting chamber through the manual sandstone of selection by winnowing.

The utility model is the corollary equipment of mine rubble production line from imitating dedusting screening sandstone machine, be used for the selected of manual sandstone, its product is because of its resistance to compression, antidetonation, the superior construction that is widely used in important foundations such as highway, airport, sea port dock of anti-wear performance.
