CN202212225U - High-purity quartz sand precomminuting device - Google Patents

Abstract

The utility model provides a high-purity quartz sand precomminuting device. The high-purity quartz sand precomminuting device comprises a comminuting tank body, wherein the tank body is divided into a feeding buffer chamber in the upper layer, a precomminuting chamber in the middle layer and a dicharging buffer chamber in the lower layer through moveable valves; and a mechanical crushing device is arranged inside the precomminuting chamber. By adopting the precomminuting device, the damage to a roll surface due to relatively large granules in the comminuting process is reduced, and the cracking problem of a roll machine caused by the sand granules in the crushing process is avoided, so that the quality of a produced product is improved.

Description

A kind of glass sand pre-crushing plant

Technical field

The utility model relates to a kind of chemical industry equipment, is specially a kind of glass sand and produces pre-crushing plant.

Background technology

Traditional pair roller breaking method is that material is directly fed from two rollers tops, begins when being bitten by roll surface; Receiving the roller active force increases gradually, after the high pressure effect that receives about 50-200MPa, discharges down with desirable granularity slave; The material of discharging, except that containing a certain proportion of granular material, the inside of all the other granule materials; Produce a large amount of crackles, be convenient in further crushing process, can reduce the grinding energy consumption significantly.

And for the glass sand industry; There is obvious defects in this traditional breaking method, and therefore the glass sand product does not need further refinement pulverizing or grinding owing to need possess certain particle or order number (40-180 order); And oarse-grained existence; Make when it goes into roller that the integral body power that is squeezed is bigger than normal, therefore inner granule also suffers high pressure, thereby makes the sand grains product occur micro-crack largely; The pair roller particle is excessive, and roll surface wear is bigger, can cause that also the quartz sand product granularity is meticulous.And after the pair roller fragmentation, possesses the quartzy sand grains of certain particle size; Its inside or surface should not have the crackle structure again; Otherwise in later stage acid treatment or washing process; Be easy to make other element or impurity absorption to be difficult for being eliminated, thereby influence the glass sand product gas purity greatly in inside, crack.

The utility model content

In order to address the above problem, the utility model spy provides a kind of glass sand pre-crushing plant, both alleviated because of particle more greatly to roll surface wear, also reduce simultaneously the crackle that sand grains produces when twin rollers is broken.

A kind of glass sand pre-crushing plant, it comprises the pulverizing tank, tank body is divided into upper strata charging surge chamber, precomminution chamber, middle level, lower floor's discharging surge chamber through Movable valve, the indoor Mechanical Crushing device that is provided with of precomminution.

Described discharging surge chamber lower end is the outlet of hourglass shape.

Said Mechanical Crushing device is a rotating vane.

Described Movable valve is the valve of periodically opening.

Compared to the integrated or independent buffer unit of traditional twin rollers, the utility model is positioned at the broken leading portion of coarse crushing back segment, pair roller, and often open charging surge chamber upper end, accepts the bulky grain that streamline sends and treats the roller material; Periodically open the lower end, material is sent into the precomminution chamber; Ore after the precomminution chamber interior adopts physics mode to coarse crushing carries out precomminution, eliminates most of large-size particle to reach; Smaller particles material inflow discharging surge chamber after precomminution is periodically opened in lower end, precomminution chamber; Discharging surge chamber lower end is the outlet of hourglass shape, and preliminary treatment streams ability of swimming is dropped into twin rollers, through such device of pulverizing in advance, alleviate because of particle more greatly to roll surface wear, also reduced the seminess that sand grains produces simultaneously when twin rollers is broken.

Description of drawings

Fig. 1 is the utility model example structure sketch map.

The specific embodiment

Like a kind of glass sand pre-crushing plant shown in the drawings, it comprises pulverizes tank 1, and tank body 1 is divided into upper strata charging surge chamber 2, precomminution chamber, middle level 3, lower floor's discharging surge chamber 4 through Movable valve 6, is provided with the Mechanical Crushing device in the precomminution chamber 3.

Described discharging surge chamber 4 lower ends are the outlet of hourglass shape.

Said Mechanical Crushing device is a rotating vane 5.

Described Movable valve 6 is the valve of periodically opening.

The course of work of present embodiment is:

Quartz mine via the jaw crusher coarse crushing after, bulky grain ore pipeline mode gets into the charging surge chamber;

Valve is every between charging surge chamber and the precomminution chamber opened once at a distance from tens of minutes, and the bulky grain ore flows into the precomminution chamber;

Treat the precomminution chamber up and down behind the valve closing, the high speed rotational blade that the indoor employing of precomminution is adjustable carries out precomminution with the mode of mechanical collision to the bulky grain ore, and the pulverizing time is suitable with valve switch cycle up and down;

The bulky grain ore is through after the precomminution in tens of minutes, and valve open between pulverizing chamber and the discharging surge chamber, flows into the discharging surge chamber through pretreated granule ore;

The appropriate setting of size process of discharging surge chamber below hourglass mouth formed a connecting link, and guarantees the pair roller fragmentation that the preliminary treatment material can evenly get into the below with pipeline mode in the processing cycle.

The utility model is practical, designs changeablely, can add production process flexibly, is used for adjusting at any time or the production line of upgrading, and does not influence the production of automation flowing water, is of value to and improves the quality of products.
