Description
Technical field
The utility model relates to biological material process equipment field, relates in particular to a kind of biomass block-making machine pressure roller.
Background technology
Biomass block-making machine is by the biomass materials such as the stalk of pulverizing, the equipment that compression forming is bulk product. Its operation principle is: porous ring mould and pressure roller are used in conjunction with, pressure roller moves in a circle around main shaft, roll along the inner circle of ring mould simultaneously, material is pressed in ring nib, pressure roller roll extrusion is constantly pressed into material, material overcomes frictional resistance reach in ring nib, and simultaneously compressed, pressurize moves forward to port of export extrusion molding product. In work, pressure roller pressing materials bears pressure, simultaneously relative with material sliding rubbing, pressure roller wheel rim place is cut by material scraper, and serious wear causes shape and size to change, the wearing and tearing of pressure roller wheel rim can affect pressure roller material is pressed into nib, cause cuber operational failure, cause producing interrupting.
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, provides a kind of antiwear property strong, and cost is low, and is convenient to the biomass block-making machine pressure roller of maintenance.
The utility model adopts following technical scheme:
The utility model comprises pressure roller body, and described pressure roller body lateral wall is provided with dovetail groove along axis direction, and described dovetail groove circumference uniform distribution, on pressure roller shaft body, is provided with the wear-resisting mosaic block matching with it in described dovetail groove.
As preferably, on described wear-resisting mosaic block He in described dovetail groove, be respectively arranged with corresponding pin hole, described wear-resisting mosaic block is fixed in dovetail groove by latch.
As preferably, between described wear-resisting mosaic block and dovetail groove, be filled with bonding agent.
As preferably, described bonding agent is epoxy resin ab glue.
As preferably, described dovetail groove α angle is 7 ~ 9 °.
As preferably, the thickness h of described wear-resisting mosaic block is 5 ~ 7mm.
As preferably, adjacent wear-resisting mosaic block interblock is apart from 6 ~ 10mm, and the length of wear-resisting mosaic block is consistent with the axial length of wheel rim, and wear-resisting mosaic block width is got 20 ~ 25mm, the quantity of dovetail groove is definite according to the width design of pressure roller diameter and wear-resisting mosaic block, and wear-resisting mosaic block 12 thickness h are 5 ~ 7mm.
The utility model good effect is as follows:
(1) pressure roller body lateral wall (being wheel rim) is bumped into the wear-resisting mosaic block that multiple hard wear-resistant materials are made, has avoided the risk of overall hard wear-resistant material pressure-bearing fracture, reached again wear-resistant withstand voltage effect simultaneously; The wearability of wear-resisting mosaic block is far away higher than pressure roller bulk material, significantly significantly improves pressure roller wear-resisting service life.
(2) wear-resisting mosaic block adopts bonding-interlocking to mix and be connected with pressure roller body, between wear-resisting mosaic block and pressure roller body, forms Gumming glue film, and this Gumming glue film has good buffering effect. Wear-resisting mosaic block mainly bear pressure and and biomass material between friction, scrape and cut, adopt the wear-resisting mosaic block made of steel bonded carbide, the ability of its hardness, wearability and pressure-bearing, is applicable to such working condition completely.
(3) the soft phase of wheel rim base metal between adjacent two wear-resisting mosaic blocks can play wheel rim groove binding, prevents from when pressure roller from rotating skidding, and favourable material is pressed into nib.
(4) bonding-interlocking mixes connection, is removable connection, heats and just can take off wear-resisting mosaic block, more renews wear-resisting mosaic block, and wear-resisting mosaic block can do generalization, standardized designs, favourable pressure roller maintenance.
