Description

A kind of preparation method and equipment of high-purity rounded quartz

technical field

The invention relates to the technical field of quartz powder processing, in particular to a preparation method and equipment for high-purity rounded quartz.

Background technique

Vertical mill is a grinding equipment that integrates fine crushing, drying, grinding, powder separation, and conveying. It is widely used in the grinding and Ultrafine grinding. The grinding process of the vertical mill is completed by a set of grinding devices (ie, grinding rollers and grinding discs), and the material is ground into powder between the grinding rollers and the grinding discs. The movement of the grinding device is driven by the rotation of the grinding disc and correspondingly drives the grinding roller to drive. The grinding pressure mainly relies on a set of hydraulic devices to pressurize the grinding disc material in addition to the self-weight of the grinding roller. There is a large amount of coarse powder in the milled material. The powder is selected by the matching powder separator. The powder selection process is through air separation. During the air flow process, most of the coarse powder automatically falls on the grinding disc and is received again. Grinding, the rest are selected by the powder separator as finished products, and sent to the finished product storage through the dust collection and conveying system.

The grinding process of quartz powder can be realized by vertical mill grinding, and the residence time of quartz powder on the grinding disc affects the quality and output of quartz powder. The residence time of the quartz powder on the grinding disc is mainly determined by three factors: 1. The rotation speed of the grinding disc which affects the centrifugal force; 2. The friction between the quartz powder and the grinding disc and the internal friction of the quartz powder itself; 3. Determine the movement stroke mode The structure and cooperation between the grinding disc and the grinding roller. The third factor is the key to determining the design ideas of various vertical mill manufacturers.

Different forms of grinding rollers and grinding discs determine the grinding speed of each manufacturer and the residence time of materials on the grinding disc. When selecting a vertical mill, the user must choose a suitable vertical mill according to the characteristics of the grinding material. In order to make the selection and replacement of vertical mills more convenient, it can be realized by replacing only different types of grinding rollers and grinding disc structures. However, the existing grinding rollers are modular assemblies formed by independent assembly, which are large in size and heavy in weight. , whether it is to replace the grinding roller or disassemble and repair, it needs a crane or other lifting equipment to achieve, the operation is difficult and the operation risk is high.

Further, the roller sleeve assembly 304 of the present invention is an assembled structure of modular design, and can assemble roller sleeves of different specifications according to grinding requirements. details as follows:

As shown in FIGS. 8-12 , the roller sleeve assembly 304 includes an inner layer sleeve 304a sleeved on the periphery of the hub 303b, an outer layer sleeve 304b sleeved on the periphery of the inner layer sleeve 304a, and a plurality of detachable and fixed outer layer sleeves 304b in the circumferential direction. The friction block 304c; the friction block 304c has various specifications, the outer surfaces of the friction blocks 304c of various specifications have different surface structures or materials, and each specification of the friction block 304c is equipped with a plurality of.

The outer diameter of the rear end of the hub 303b is larger than the outer diameter of the front end, and the inner side wall of the inner layer sleeve 304a is fitted to the outer side wall of the hub 303b; the outer diameter of the rear end of the inner layer sleeve 304a is larger than the outer diameter of the front end, forming a conical surface, and the outer layer The inner sidewall of the sleeve 304b is attached to the outer sidewall of the inner layer sleeve 304a.

The inner sleeve 304a and the outer sleeve 304b are conical sleeve structures nested in sequence on the periphery of the hub 303b.

A roller sleeve pressing plate 303p is detachably mounted on the front end surface of the hub 303b, and the outer edge of the roller sleeve pressing plate 303p presses the front ends of the inner layer sleeve 304a and the outer layer sleeve 304b. Axial limit to prevent loosening. Preferably, the roller sleeve pressing plate 303p is an annular structure, which surrounds the periphery of the front end cover 303h, and the roller sleeve pressing plate 303p is fixed on the hub 303b by a plurality of hexagon socket head bolts distributed in the circumferential direction.

Further, the outer edge of the inner side of the roller sleeve pressing plate 303p is set as a chamfer 303p-1, and the front ends of the inner sleeve 304a and the outer sleeve 304b are set to fit the annular slope P of the chamfer 303p-1, This facilitates the contact and fit of the roller sleeve pressing plate 303p to the inner layer sleeve 304a and the outer layer sleeve 304b.

Further, slots 304b-1 corresponding to each friction block 304c are distributed on the outer sleeve 304b in the circumferential direction; A transparent slit 304b-2 is provided on the outside, and the width of the slit 304b-2 is smaller than the width of the slot 304b-1; and the slot 304b-1 and the corresponding slit 304b-2 together form a front opening, a rear end Blocked T-slots.

The friction block 304c includes an arc-shaped friction plate 304c-1, an engaging strip 304c-2 fixed on the inner surface of the arc-shaped friction plate 304c-1, and a plug plate 304c-3 fixed on the engaging strip 304c-2.

The structure of the connecting strip 304c-2 is matched with the slit 304b-2, and the structure of the insert plate 304c-3 is matched with the slot 304b-1. When inside any slot 304b-1, the inner side surface of the arc friction plate 304c-1 is abutted with the outer side surface of the outer sleeve 304b.

When a corresponding friction block 304c is inserted and fixed in each slot 304b-1, the two side edges of each arc-shaped friction plate 304c-1 can be connected to each other with the edges of the adjacent arc-shaped friction plate 304c-1. In addition, each arc-shaped friction plate 304c-1 can be connected in sequence to form a conical sleeve structure enclosing and surrounding the outer sleeve 304b.

Further, the present invention provides that: the outer sleeve 304b forms a blocking column 304b-4 between the adjacent slots 304b-1.

All the other blocking pillars 304b-4 except one of the blocking pillars 304b-4 are provided with arc-shaped channels 304b-3 extending in the circumferential direction and having two transparent ends.

The arcuate channel 304b-3 includes a first sliding section 304b-31 and a second sliding section 304b-32 that communicate with each other, the second sliding section 304b-32 having a greater longitudinal depth than the first sliding section 304b-31, and A limiting step surface 304b-5 with changing cross-section is formed at the junction of the two.

Each arc-shaped channel 304b-3 is slidably provided with an arc-shaped sliding rod 304d, two ends of the arc-shaped sliding rod 304d are symmetrically provided with a wedge-shaped plug 304d-1, and the end of the wedge-shaped plug 304d-1 has a pressure-receiving slope 304d- 2. The pressure-receiving slope surface 304d-2 tends to gradually approach the bottom surface of the arc-shaped channel 304b-3 from the inside to the outside (ie, the pressure-receiving slope surface 304d-2 tends to incline backwards from the inside to the outside).

Except for one of the friction blocks 304c, one side of the insert plate 304c-3 of each other friction block 304c is provided with locking grooves 304c-31 which are matched with the wedge-shaped insert block 304d-1; or, in order not to distinguish the friction blocks 304c, In order to be able to take any friction block 304c at random, locking grooves 304c-31 can be directly provided on the inserting plate 304c-3 of each friction block 304c.

Preferably, the locking grooves 304c-31 include a matching slope A matched with the pressure-receiving slope 304d-2 and a limiting plane B on the other side.

An outer protrusion 304d-3 extending into the second sliding section 304b-32 is also fixed on the arc-shaped sliding rod 304d, and an elastic member 304e is disposed between the outer protrusion 304d-3 and the limiting step surface 304b-5. The elastic member 304e adopts a compression spring, which has a restoring effect on the sliding of the arc-shaped sliding rod 304d in the arc-shaped channel 304b-3.

A pair of friction blocks 304c corresponding to both sides of the blocking column 304b-4 without the arc-shaped channel 304b-3 are connected and fixed by the connecting plate 304f, so that the connecting plate 304f covers the blocking column 304b-4. peripheral. Specifically, both ends of the connecting plate 304f are respectively fixed to the front ends of the friction blocks 304c on both sides by screws.

When the elastic member 304e is in the natural state, the pressing slope 304d-2 of one of the wedge-shaped inserts 304d-1 on the arc-shaped sliding rod 304d just fully exposes the second sliding section 304b-32 or partially exposes the second sliding section 304b-32. The sliding section 304b-32 extends into a slot 304b-1 adjacent thereto, and the other wedge-shaped insert block 304d-1 is all received in the first sliding section 304b-31.

The assembly method and assembly principle of the roller sleeve assembly 304 of the present invention are as follows:

As shown in FIG. 12 , the friction blocks 304c are sequentially inserted in the respective slots 304b-1 of the outer sleeve 304b in a clockwise direction. In the process of inserting the friction blocks 304c one by one, when the friction blocks 304c are inserted into the corresponding slots 304b-1 on the outer sleeve 304b through the plug-in plate 304c-3 on the friction block 304c, the plug-in plate 304c-3 can be squeezed and extended to The pressure-receiving slope 304d-2 of the wedge-shaped insert 304d-1 in the slot 304b-1 pushes the corresponding arc-shaped sliding rod 304d to slide relatively counterclockwise in its arc-shaped channel 304b-3, so that the The other wedge-shaped plug 304d-1 of the arc-shaped sliding rod 304d is inserted into the locking groove 304c-31 of the previous plugboard 304c-3 that has been slid into the adjacent groove 304b-1 in the counterclockwise direction. The insertion of one friction block 304c can lock and limit the previous inserted friction block 304c. Therefore, except for the last inserted friction block 304c, other friction blocks 304c can be fixed step by step, while the last friction block 304c can be fixed step by step. The block 304c can be fixed by the connecting plate 304f, and finally the assembly of all the friction blocks 304c is completed.

Since the above-mentioned assembly process is generally the direct insertion of each friction block 304c (the locking process occurs automatically), the assembly is simple and fast, saving time. Moreover, since the roller cover assembly 304 is divided into a plurality of modules, the weight is small, and the manual operation is easy.

The friction block 304c of the present invention includes different structural forms (the outer surfaces of different friction blocks 304c have different structures/materials). By selectively installing different friction blocks 304c on the periphery of the outer sleeve 304b, different specifications and grinding can be assembled. The roller sleeve assembly 304 can achieve the effect, and the roller sleeve assembly 304 can be directly installed and applied on the wheel hub 303b to realize different grinding processes and obtain different product quality/yield. Therefore, the structure of the roller cover assembly 304 can be made flexible and changeable, and the applicability is wider; in actual disassembly and replacement, the entire grinding mechanism 300 does not need to be replaced, which is safe, reliable, and time-saving.

Preferably, the friction block 304c of the present invention includes at least three types:

1. The first friction block 304c: it is made of 42CrMo-A steel by one-time forging, and its outer surface is surfacing by surfacing, the thickness of the wear-resistant layer is 15-20mm, and the hardness is HRC56-60;

2. The second type of friction block 304c: the metal base is mainly used to meet the ceramic, and the outer surface of the ceramic is in a honeycomb structure, which reduces the surface friction and has a lower grinding capacity than the first type;

3. The third friction block 304c: made of high-chromium cast iron abrasive material, the crack resistance, wear resistance and load bearing capacity are stronger than the former two.

In actual use, the selection of various friction blocks 304c can be unified or mixed (eg, the first type of friction block 304c and the second type of friction block 304c are alternately interspersed at intervals), so that a variety of different application modes will be obtained.
