Description

Horizontal bead mill with replaceable inner sleeve

Technical Field

The utility model relates to grinding equipment, in particular to a horizontal bead mill.

Background

The common horizontal bead mill is a machine which is arranged in a horizontally-arranged fixed cylinder grinding cavity and is provided with a plurality of rotary grinding discs (or deflector rods or bar pins) and various grinding bodies for grinding materials. The grinding medium is typically wortmax sand, glass beads, steel or ceramic beads, or the like. The materials are subjected to comprehensive actions such as powerful shearing, centrifugal extrusion, liquid layer friction, impact tearing, turbulence and the like in the grinding inner cavity, and the filter screens with specific gaps arranged at the two ends are used for forced filtration and the like, so that the solid phase, the liquid phase and the gas phase which are not compatible are uniformly and finely emulsified instantaneously under the combined action of the corresponding maturation process and a proper amount of additives, and the products with stable fineness are finally obtained through high-frequency cyclic reciprocation.

The grinding cylinder of the horizontal bead mill in common application is integrated, and the manufacturing materials of the horizontal bead mill are generally stainless steel, zirconia ceramics and other materials. Stainless steel has poor wear resistance, pollutes materials, is influenced by structural property, has non-ideal service life cycle and has high zirconia processing cost. In addition, because of the change of the processing materials, the cost for replacing the whole grinding cylinder is too high, and waste is caused. In addition, the high heat generated by the materials in the processing process seriously affects the quality of the materials and the service life of the bead mill.

Disclosure of Invention

The utility model aims to solve the defects in the prior art and provides a horizontal bead mill with an exchangeable inner sleeve. Compared with the prior equipment, the utility model prolongs the service life and reduces the cost.

The utility model is realized in this way, a horizontal bead mill with a replaceable inner sleeve comprises a frame unit, a motor unit and a grinding unit driven by the motor unit are arranged on the frame unit, the grinding unit comprises a belt pulley, a bearing seat, a main shaft, a mechanical seal and a grinding cavity, the grinding cavity is divided into an inner grinding cylinder and an outer grinding cylinder, and a gap is reserved between the inner grinding cylinder and the outer grinding cylinder.

The horizontal bead mill with the replaceable inner sleeve is characterized in that a cylinder cover of the milling cavity and the outer milling cylinder are sealed by bolts, the inner milling cylinder is provided with a sealing cover, the sealing cover and the inner milling cylinder are sealed by bolts, and the sealing cover is positioned in the cylinder cover.

The horizontal bead mill with the replaceable inner sleeve is characterized in that a gap between the inner grinding cylinder and the outer grinding cylinder is a cooling water channel, and a cooling water guide plate is arranged in the gap.

The utility model adopts a novel structure of the grinding cylinder, the original integrated grinding cylinder is split into the inner grinding cylinder and the outer grinding cylinder, when the inner grinding cylinder is severely worn or is replaced by different materials, the inner grinding cylinder is replaced in time, the whole grinding cylinder is not required to be replaced, and the cost is reduced. A large gap is formed between the outer grinding cylinder and the inner grinding cylinder after the splitting, the grinding cylinder and the materials are cooled by water, the quality of the materials is improved, and the service life of the bead mill is prolonged.

Drawings

The utility model is further described below with reference to the accompanying drawings:

FIG. 1 is a schematic view of the structure of the grinding unit;

fig. 2 is a schematic view of the structure of the grinding chamber.

Description of the embodiments

Referring to fig. 1 and 2, the horizontal bead mill of the present utility model mainly includes a frame unit, a motor unit, and a grinding unit;

the grinding unit mainly comprises a belt pulley 1, a bearing seat 2, a main shaft 3, a mechanical seal 4, a grinding cavity 5 and the like, wherein the structure diagram of the grinding cavity is shown in fig. 1, the grinding cavity comprises an outer grinding cylinder 6, an inner grinding cylinder 7, a guide vane 8, a gland 9 and a cylinder cover 10, and the structure of the grinding cavity is shown in fig. 2. The cylinder cover 10 and the outer grinding cylinder 6 of the grinding cavity are sealed by bolts, the inner grinding cylinder is provided with a sealing cover, the sealing cover and the inner grinding cylinder are sealed by bolts, and the sealing cover is positioned in the cylinder cover.

When the grinding cylinder is severely worn or the material is replaced and the grinding cylinder is required to be replaced, the whole replacement is not required, the screw is loosened to remove the cylinder cover 10, the screw is loosened to remove the gland 9, and then the inner grinding cylinder 7 is taken out to be replaced. Then the gland and the cylinder cover are assembled according to the method;

as shown in fig. 2, a guide plate 8 is arranged between the gaps of the outer grinding cylinder 6 and the inner grinding cylinder 7, and cooling water is introduced to cool materials, so that the service life of the bead mill is prolonged.
