Abstract
The utility model discloses a dustproof cover for a fixed shaft of a high-pressure paired-roller squeeze mill. The dustproof cover comprises a base, bearing pedestals arranged on the base, and a fixed shaft, wherein the fixed shaft comprises supporting end parts at two ends and stress shaft shoulder parts arranged on the inner sides of the two ends; the supporting end parts are positioned in the bearing pedestals. The dustproof cover further comprises cover bodies fixedly arranged on the base and sealing baffles which are fixedly arranged on the fixed shaft and are positioned on the stress shaft shoulder parts, wherein the cover bodies are barrel-shaped and are sleeved at transitional positions of the stress shaft shoulder parts and the supporting end parts of the fixed shaft; the sealing baffles and the fixed shaft can rotate synchronously. The dustproof cover for the fixed shaft of the high-pressure paired-roller squeeze mill can perform dustproof protection on main abraded parts of the fixed shaft, so that the phenomena that the working energy consumption of the high-pressure paired-roller squeeze mill is increased and the service life of the high-pressure paired-roller squeeze mill is shortened due to friction between stress shaft shoulders of the fixed shaft and the bearing pedestals are avoided.
Description
Technical field
The utility model relates to a kind of dust cover of high pressure roller extruding grinding machine dead axle, belongs to high pressure disintegrating apparatus technical field.
Background technology
The main working parts of high pressure roller grinder is two cylindrical roller pinch rollers that are arranged in parallel, and when equipment work, material is involved between two rolling wheel set also crushed; One of them roll-in crop rotation System of Rotating about Fixed Axis motion, another rolling wheel set its axis in rotary course can move, to adapt to by the degree of irregularity of crushing material.Pressure between high pressure roller grinder two rollers is generally 50～300 MPa, and therefore rolling wheel set can be subject to very large shock loading in the course of the work, causes horizontal vibration and twisting vibration that main shaft is strong.For this reason, the main shaft of high pressure roller grinder can be designed to syllogic, rolling wheel set is installed at the maximum gauge place, middle part that is main shaft, the minimum diameter place, two ends of main shaft is arranged in bearing block for supporting, the stress shaft shoulder is set between the middle part of main shaft and two ends, bears the mechanical strength of horizontal vibration and twisting vibration to improve main shaft.
Conventionally in the working environment of high pressure roller extruding grinding machine, dust is more, and high pressure roller squeezing mill machine is manufactured and maintenance cost is all higher, therefore need to pay attention to especially the anti-dust performance of high pressure roller extruding grinding machine, to reduce wearing and tearing and the maintenance cost of moving component, and main shaft especially, its active force bearing is large, in the process of running, between its stress shaft shoulder and bearing block, enter dust, easily cause the work energy consumption of high pressure roller extruding grinding machine to raise, the rate of wear of main shaft and bearing block is accelerated, and has reduced the service life of high pressure roller extruding grinding machine.
Utility model content
The deficiency that the utility model exists for prior art just; a kind of dust cover of high pressure roller extruding grinding machine dead axle is provided; can carry out proofing dust and protecting to the main abrading section of dead axle, produce with the stress shaft shoulder and the bearing block of avoiding dead axle the rising of work energy consumption and the shortening in service life that friction causes high pressure roller extruding grinding machine.
For addressing the above problem, technical solution adopted in the utility model is as follows:
A dust cover for high pressure roller extruding grinding machine dead axle, comprises base and is arranged at the bearing block on base, and dead axle;
Described dead axle comprises the stress axis shoulder inside supporting base end portion and the two ends that are positioned at two ends, and described supporting base end portion is arranged in described bearing block; Also comprise and be fixedly arranged on the cover body of described base and be fixedly arranged on described dead axle and be positioned at the sealing baffle of described stress axis shoulder, described cover body is tubular and the stress axis shoulder that is set in described dead axle and the crossover position of supporting base end portion, and described sealing baffle is synchronizeed and rotated with described dead axle.
As the improvement of technique scheme, described sealing baffle comprises columnar connecting portion and dust-break portion, and described dust-break portion place face is perpendicular to the axis of described dead axle, and the connecting portion inner side welding of described sealing baffle is arranged on described dead axle.
As the improvement of technique scheme, also comprise wool felt, described wool felt is arranged between described cover body and described sealing baffle.
As the improvement of technique scheme, described cover body arranges groove, and described wool felt is arranged in described groove.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
The dust cover of high pressure roller extruding grinding machine dead axle described in the utility model, the dust that can prevent preferably location axle roll pinch roller position flies away and deposits to the crossover position of described stress axis shoulder and described supporting base end portion, be deposited on the wearing and tearing that the dust of the crossover position of described stress axis shoulder and described supporting base end portion causes bearing block and described dead axle comparatively obvious, reduce loss and energy consumption that above-mentioned wearing and tearing can significantly reduce high pressure roller extruding grinding machine, and reduce its maintenance cost.
Accompanying drawing explanation
Fig. 1 is the dust cover structure schematic diagram of high pressure roller extruding grinding machine dead axle described in the utility model.
The specific embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Figure 1, push the dust cover structure schematic diagram of grinding machine dead axle for high pressure roller described in the utility model.The dust cover of high pressure roller extruding grinding machine dead axle described in the utility model, comprises base and is arranged at the bearing block 1 on base, and dead axle; Described dead axle comprises the stress axis shoulder 3 inside supporting base end portion 2 and the two ends that are positioned at two ends, and described supporting base end portion 2 is arranged in described bearing block 1; Also comprise and be fixedly arranged on the cover body 4 of described base and be fixedly arranged on described dead axle and be positioned at the sealing baffle of described stress axis shoulder 3, described cover body 4 is for tubular and be set in the stress axis shoulder 3 of described dead axle and the crossover position of supporting base end portion 2, and described sealing baffle is synchronizeed and rotated with described dead axle.Described structure can prevent that the dust at location axle roll pinch roller position from flying away and depositing to described stress axis shoulder 3 and the crossover position of described supporting base end portion 2 preferably, be deposited on described stress axis shoulder 3 comparatively obvious with the wearing and tearing that the dust of the crossover position of described supporting base end portion 2 causes bearing block 1 and described dead axle, reduce loss and energy consumption that above-mentioned wearing and tearing can significantly reduce high pressure roller extruding grinding machine, and reduce its maintenance cost.
