Abstract

The utility model discloses a clay rolling mill with a screen filter, which is a rolling annealing filter machine used for clay materials. The clay rolling mill with screen filter is characterized in that the clay rolling mill with a screen filter is provided with two rollers which are distributed with pores, the two rollers are respectively driven by two electric motors to do relatively rotary motion, the two electric motors have the same power and rotation speed, the upper part of the clay rolling mill with screen filter is provided with a feed hopper, and the lower part of the clay rolling mill with screen filter is provided with an impurity conveyer belt and a material cleaning conveyer belt. When clay materials go into a wedge area between the two rollers via the feed hopper, the clay materials are rolled and crushed; under the action of the roller compaction force, the clay materials fall onto a material cleaning belt conveyer after passing through the pores of the two rollers and are loaded into the next process; the hard lumps and impurities which can not pass through the pores of the two rollers fall onto an impurity belt conveyer to be unloaded, as a result, the clay materials are filtered to remove the impurities.

Description

Clay rolling mill with screen filter

The utility model belongs to the stone roller of clay material and practices screening machinery.

In the production process of clay hollw article, need carry out fragmentation, grind white silk, remove impurity, to improve the performance of pug to pug.At present, filtering twin rollers is the novel mechanical that in the world pug is ground white silk, impurity elimination processing.

Its structure is by two different capacities, same speed motor, on two parallel axes of Dai Donging, roller (1) and (4) of belt material plate (9) is housed respectively, is fixed on the frame (5) by bearing block.Establish loading hopper (3) on the top of two rollers, impurity belt feeder (6) and clean funnel (7) are established in the bottom.All offer densely covered aperture on two rollers and the liner plate.

Its operation principle is when pug enters in relative rotation between two rollers wedge area by loading hopper, is subjected to rolling fragmentation, under the grinding pressure effect, behind the aperture, falls on the clean material belt on the logical pair roller of pug, sends into next procedure; And under the grinding pressure effect, can not force the swing of swing roller by the lump impurity of aperture, and making to present the gap between two rollers, lump impurity is just drawn off from falling between two rollers on the impurity belt feeder of bottom.After impurity was removed, roller resetted under the effect of spring (8), so far pug had been reached to filter and grind to practice to act on.

Existing deficiency of filtering the twin rollers existence is that the aperture on the roller is practiced process at the stone roller to pug, and wearing and tearing are big, cause roller wall wear down, bore deformation, and the life-span of roller is short.

The purpose of this utility model is to improve by the panel to roller, needs to change the trouble of roller and reduces maintenance cost because of wearing and tearing with minimizing, and improve output, improves the economic benefit of this machine.

Feature of the present utility model on roller, mat formation one deck loading and unloading capable of being combined, be provided with the thin lining plate of the aperture that gathers, the size of aperture is slightly littler than orifice size on the roller on the liner plate, two-layer hole is combined into stepped hole.Pass becomes straight hole, is beneficial to by pug, is convenient to processing and manufacturing.

Can unload replacing at any time after the utility model has the advantages that wear liner.Shoulder hole is formed in hole on the liner plate and the hole on the roller, can reduce pug by the time resistance, improved and rolled efficient.

11. shoulder hole;

Embodiment: two roller diameters of this filtration twin rollers are 1600 millimeters of φ, and roller is wide 600 millimeters.Two roller surfaces are all laid the liner plate that one deck is connected into by 8 arcs.Establishing the aperture on two rollers is 18 millimeters of φ, and respective aperture is 15 millimeters of φ on the liner plate.Liner plate is solid on the roller wall with screw.When dropping into water content through the coarse crushing pug 18～20%, when the roller rotating speed is 18 rev/mins, can roll smoothly, expect only output can reach 30～40 cubic metres/time.

Claims

1, a kind of by frame, fixedly roller, can swing roller, loading hopper, clean funnel, spring, impurity belt feeder, expect to it is characterized in that the filtration twin rollers that belt feeder and driving section grade and form liner plate is housed on roller only, densely covered aperture is arranged on the liner plate.

2, filtration twin rollers as claimed in claim 1 is characterized in that stepped through hole is formed in aperture and the hole on the roller on the liner plate.
