Abstract
The utility model relates to a mine blower rotor capable of adjusting blades, which comprises the blades, blade shafts, a wheel hub and a rotor. The utility model is characterized in that the inner end of each blade shaft is connected with corresponding adjusting arms through keys; the inner end of the adjusting arm is connected with sliding blocks through a connecting member; an adjusting shaft is screwed at the middle of the rotor, and is rotatably connected with an adjusting disc; the outer edge of the adjusting disc is provided with a sliding groove; the sliding blocks at the inner end of each adjusting arm are assembled in the sliding groove; and a guide rod passing through the adjusting disc is arranged on the rotor. The utility model has the advantages that all blades of the rotor can be adjusted once; and the blade adjusting time can be saved and can be shortened by more than 70%. The opening process and the closing process are completely synchronous, so the adjusting angles of mine blower blades are completely accordant; air flow vibration generated according to different blade angles when single blade is adjusted is avoided; eddy currents can not generate to influence the efficiency of a blower; and simultaneously, the mine accident occurring probability is reduced, and the continuous safe production of mines is realized. The utility model has wide air flow adjusting range, and can match with the output quantity of mineral products and can meet the use requirement.
Description
Technical field
It is the mine fan structure that the utility model belongs to a kind of, the particularly a kind of mine fan rotor that can conveniently adjust blade.
Background technique
The characteristics of mine are the increases along with exploitation length, and the amount that needs ventilation is also increasing progressively gradually.This blower fan that just requires to be used for mine ventilation not more the situation down conversion angle of fan leaves of ventilating fan change the ventilation of blower fan, take place to require blower fan can return wind under the urgent situation at mine in addition.The blower fan that is used for mine ventilation at present mainly exists following shortcoming: a, blower fan whole efficiency low, particularly in early stage.B, air quantity regulation range are little, can not mate with the quantum of output of mineral products.C, blade adjustments trouble need a slice a slice blade adjustments.D, to return air quantity little, in case urgency takes place in the down-hole, returning air quantity can't meet the demands.
The model utility content
The purpose of this utility model provides a kind of mine fan rotor that can conveniently adjust blade, and blade adjustments is convenient, fast, and the adjusting angle unanimity is avoided airstream vibration and eddy current, improves the efficient of blower fan.
The purpose of this utility model is achieved by the following technical solution: it comprises blade, sharf, wheel hub, rotor, it is characterized in that: the inner of each sharf connects corresponding regulating arm by key, the inner of regulating arm connects slide block by link, adjusting axle is threaded at the rotor middle part, adjustment disk is rotationally connected on the adjusting axle, the outer rim of adjustment disk is provided with chute, and the slide block of each regulating arm the inner is assembled in the chute.The guide rod that passes adjustment disk is set on rotor.
The utility model compared with prior art, have following sorrow point: 1, all blades of rotor are once adjustable, save the adjusting vane time, the adjusting time shortens more than 70%.2, synchronous fully in the switching process, make the adjusting angle of mine fan blade in full accord, the efficient of different airstream vibrations that produce of blade angle and generation vortes interference blower fan reduces the probability that mine has an accident simultaneously when avoiding individual blade to regulate, and realizes the continuous safety in production of mine.3, the air quantity regulation range is big, and the fine coupling of quantum of output energy with mineral products can finely satisfy usage requirement.
Description of drawings
Fig. 1 is a general structure schematic representation of the present utility model.
Fig. 2 is a regulating arm part-structure enlarged diagram.
Fig. 3 is an adjustment disk part-structure enlarged diagram.
Embodiment
See Fig. 1-3, concrete structure of the present utility model is as follows: each blade 1 is connected on the corresponding sharf 4 by bolt 2, stable equilibrium hammer 3 on the sharf 4.The inner of each sharf 4 connects corresponding regulating arm 5 by key, the inner of regulating arm 5 connects slide block 6 by link, adjusting axle 8 is threaded at rotor 9 middle parts, adjustment disk 10 is rotationally connected on the adjusting axle 9, the chute 11 that the outer rim setting of adjustment disk 10 is made of forward and backward back-up ring, the slide block 6 of each regulating arm 5 the inner is assembled in the chute 11.Fixed guide bar 7 on rotor 9, and guide rod 7 passes adjustment disk 10, make the adjustment disk 10 can only axial displacement.
Principles of Regulation: during adjusting vane 1, rotate adjusting axle 8 along different direction, adjustment disk 10 will move around vertically.The slide block 6 of chute 11 each regulating arm of effect of adjustment disk 10, and then drive regulating arm 5 around sharf 4 rotations, sharf 4 drives blades 1 and rotates together, realizes disposable adjusting vane angle.
The utility model is applicable to fields such as various collieries, metallic ore, tunnel ventilation.
