Abstract
The utility model provides a refining plate used on a disc refiner. The refining plate comprises refining teeth and a refining plate matrix which are respectively formed through double processing forming, and a central shaft around the refining plate matrix; the refining teeth are uniformly arranged on the refining plate matrix in a manner of concentric circles; pulp retaining plates are arranged between adjacent refining teeth; and helical pulp retaining lines are formed on the surface of the refining plate matrix by the pulp retaining plates on the same circle. The refining plate has the advantages of good pulp refining effect and long service life; and furthermore, as the refining plate adopts a double-forming method, the material cost of the refining plate is greatly reduced, and the material waste is decreased.
Description
Technical field
The utility model relates to middle dope platen grinding machine technical field, particularly a kind of abrasive disc that is used for disc mill.
Background technology
Abrasive disc is the vital part of middle dope platen grinding machine, belong to consumable accessory, therefore on producing except requiring abrasive disc to have the good refining effect, also require abrasive disc must have the mechanical tenacity that good wear resistance can and be resisted certain shock loading, require abrasive disc must have long service life simultaneously, with reach keep producing in pulp quality steady in a long-term and reduce the purpose of pulping quality fluctuation.And in actual production, the key factor that influences the refining effect long-term stability is the roll flute quality of abrasive disc in fact, roll flute is as the stressed member of abrasive disc, the length in its life-span has determined the life-span length of whole abrasive disc, but the abrasive disc structure majority that uses at present is the structure of roll flute and abrasive disc matrix integral type, this just makes roll flute and abrasive disc matrix must adopt identical materials to make, and is very unfavorable to the cost control of high life abrasive disc.And present abrasive disc adopts cast iron or steel alloy integral casting forming usually, though cast iron is cheap, good stability is not easy distortion, and its maximum shortcoming is that hardness is low, wears no resistance, and service life is short; Simultaneously, because abrasive disc adopts the one-step casting moulding, this is problems such as the abrasive disc yield rate is low, waste of material with regard to occurring easily, therefore cause the price of high life abrasive disc higher.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and the abrasive disc that is used for disc mill that a kind of refining effect is good, service life is long is provided.
The utility model is achieved through the following technical solutions: a kind of abrasive disc that is used for disc mill, comprise roll flute and abrasive disc matrix through the machine-shaping of twice difference, central shaft around the abrasive disc matrix, it is evenly distributed on the abrasive disc matrix that roll flute is a plurality of concentrically ringed states, be provided with baffle between described each roll flute, each baffle that is positioned on the same circle forms spiral helicine retaining slurry line at the abrasive disc matrix surface.
The centre bore of described abrasive disc matrix is the cylindrical hole that top has the back taper structure.
The material of described roll flute is hardness and the higher high-abrasive material of intensity, as steel alloy or pottery etc.
The material of described abrasive disc matrix is lighter weight, a toughness low melting material preferably, as aluminium or rubber etc.
When above-mentioned abrasive disc uses, regulate the distance between two abrasive discs that match according to the concentration of paper pulp, output and quality requirement, roll flute carried out defibrination when abrasive disc rotated, and the pulping that obtains throws away abrasive disc according to the trend of retaining slurry line, received by being located at abrasive disc collection container on every side.
Be used to make the abrasive disc manufacture method that is used for disc mill of above-mentioned abrasive disc, may further comprise the steps:
(1) makes the required roll flute of abrasive disc and it is carried out surface treatment;
(2) according to the abrasive disc form of design, carry out Mould Machining;
(3) after Mould Machining is finished, each roll flute and baffle are installed on the mould according to the abrasive disc form that designs;
(4) in the mould that installs roll flute, cast or vulcanize, in the time of moulding abrasive disc matrix roll flute is fixed on the abrasive disc matrix, begin to take shape abrasive disc;
(5) cooling back withdrawing pattern, so far abrasive disc is made.
The processing method of described roll flute is casting, forging or machining.
That the surface treatment of described roll flute comprises is modified, in the hardening, carburizing, spraying one or more.
The material melting point of described mould is higher than the material melting point of abrasive disc matrix, general carbon steel or the higher materials of other fusing point of adopting more.
Compared with prior art, the utlity model has following beneficial effect:
1, abrasive disc of the present utility model is made owing to two kinds of different materials of its roll flute and abrasive disc matrix adopting, therefore according to actual needs as long as improve the hardness and the intensity of roll flute, this has also reduced abrasive disc when increasing abrasive disc service life material cost reduces the waste of material.
2, abrasive disc of the present utility model adopts the processing method of post forming, has overcome the low shortcoming of yield rate of abrasive disc one-step casting moulding, has improved the yield rate of abrasive disc, reduces the waste of material, has also reduced the price of abrasive disc finished product; Simultaneously, the production of roll flute can also realize producing in batches, has improved production efficiency greatly and has reduced the production cost of abrasive disc.
When 3, abrasive disc of the present utility model uses,,, thereby reduce the waste of material because therefore the abrasive disc matrix adopting fusing point material more much smaller than roll flute can be reused for the post forming of new abrasive disc by fusion when roll flute may wear to can not re-use the time.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
A kind of abrasive disc that is used for disc mill of present embodiment, its structure as shown in Figure 1, comprise roll flute 1 and abrasive disc matrix 2 through the machine-shaping of twice difference, central shaft around abrasive disc matrix 2, it is evenly distributed on abrasive disc matrix 2 that roll flute 1 is a plurality of concentrically ringed states, wherein be provided with baffle 3 between each roll flute 1, each baffle 3 that is positioned on the same circle forms spiral helicine retaining slurry line on abrasive disc matrix 2 surfaces.
As shown in Figure 2, the centre bore of abrasive disc matrix 2 is the cylindrical hole that top has the back taper structure, and being provided with of this back taper structure is beneficial to flowing of paper pulp in the abrasive disc.
In the above-mentioned abrasive disc, the material of roll flute 1 is hardness and the higher high-abrasive material of intensity, as steel alloy or pottery etc.; The material of abrasive disc matrix 2 is lighter weight, a toughness low melting material preferably, as aluminium or rubber etc.
