The utility model can timely and effectively cool the high temperature transferred from the impeller through the fan shaft, prevent the high temperature from further transferring into the bearing base, and ensure the normal operation of the fan; therefore, the utility model can be widely use in the shaft cooling of various high temperature fans.
Description
Technical field the utility model relates to a kind of cooling unit, especially high-temperature blower axle cooling unit.
Background technique is present, in industrial fields such as metallurgy, cement, boiler, is using a large amount of high-temperature blowers, to carry the high temperature gas medium more than 450 ℃.In these high-temperature blowers, people prevent that in order to guarantee their normal operation high temperature is passed to bearing portion through main shaft, cause bearing failure, thereby cause the blower fan unit to break down, the Chang Peiyong cooler cools off main shaft, and various high-temperature blower was equipped with as commercially available.Its axle center that constitutes blower fan main shaft is a cavity, an end of its nearly blade be sealing, the other end is provided with opening, is equipped with the water-cooling tube that connects the water source in the cavity.During use, cooling water is sent into cavity bottom by water-cooling tube, is flowed out by opening behind the approach cavity again.But this cooler exists deficiency, and at first, cavity is positioned at the axle center of blower fan main shaft, has reduced the intensity of main shaft, for guaranteeing its intensity, will increase the diameter of main shaft, has caused the increase of manufacture cost; Secondly, the water-cooling tube that gos deep into cavity bottom is difficult to location and fixing, and along with the prolongation of service time, the water-cooling tube of cavity bottom very easily rubs mutually with main shaft, both generates heat, and has increased the input power of blower fan again; Once more, for the backwater that prevents cooling water flows to the outer surface of blower fan main shaft or infiltrates fan bearing, collect between the blower fan main shaft of the shell of backwater and rotation and all be equipped with seal ring, this seal ring very easily weares and teares, and has increased the cost of operation and maintenance.
The summary of the invention the technical problems to be solved in the utility model provides a kind of simple in structure, practical for overcoming deficiency of the prior art, uses high-temperature blower axle cooling unit more easily.
The technological scheme that is adopted comprises blower fan axle and the impeller on it, and the bearing support that assembles movingly with the blower fan axle, particularly be equipped with the cooling water bag on the blower fan axle between impeller and bearing support, said cooling water bag is a blower fan outer shaft sleeve Feng Youshui ladle shell, the upper and lower part of said water ladle shell is equipped with inlet tube and outlet tube respectively, the airtight respectively backwater ring that is connected with on the side walls of middle part in it, be fixed with a pair of water holding ring on the blower fan axle between the said backwater ring, the outward flanging of the edge symmetry of said water holding ring and covered said backwater ring.
As the further improvement of technological scheme, described intake pipe be positioned at water holding ring directly over; Be equipped with annular backwater bar on the described backwater ring; Described annular backwater bar is a semicircle shape, and places the first half of backwater ring; Be equipped with inlet valve on the described intake pipe.
Beneficial effect with respect to prior art is, one, cooling water bag between draught fan impeller and bearing support, to cool away from the high temperature that draught fan impeller passes over via the blower fan axle timely and effectively, blocked the further conduction of high temperature to bearing support, guarantee the normal operation of blower fan axle and bearing support, stopped the generation of blower fan unit fault; Its two, inlet tube and outlet tube places the upper and lower part of water ladle shell respectively, makes cooling water not need external force just can fall straight to blower fan axle that is cooled and timely discharge water ladle shell, has saved the power source of cooling water, has reduced user cost; They are three years old, the cooperation of water holding ring and backwater ring, make the cooling water that drops on the blower fan axle can only be via dropping down to outlet pipe between backwater ring and the water ladle shell madial wall, and not with the wind arbor flow to or infiltrate bearing support, save the seal ring of water ladle shell and blower fan between centers; Its four, the annular backwater bar on the backwater ring can be arranged to outlet pipe backwater as soon as possible, is unlikely to be detained at the root of backwater ring; Its five, by regulating the inlet valve on the intake pipe, the flow size of may command cooling water, thereby the speed of control cooling make its blower fan of adapted can be applicable to the use occasion of different high temperature grades.
Description of drawings is described in further detail optimal way of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is a kind of basic structure schematic representation of the present utility model;
Fig. 2 is the cutaway view Amplified image of the cooling water bag among Fig. 1.
Embodiment is referring to Fig. 1 and Fig. 2, and blower fan axle 5 assembles movingly with bearing fan 4, and an end of blower fan axle 5 is equipped with the draught fan impeller 2 that places Blower Housing 1, and cooling water bag 3 is loaded on the blower fan axle 5 of 4 of impeller 2 and bearing supports.Wherein, being constructed as follows of cooling water bag 3: water ladle shell 32 covers are encapsulated in outside the blower fan axle 5, and are fixedly connected with Blower Housing 1; Intake pipe 30, bottom that the top of water ladle shell 32 is equipped with serial connection inlet valve 31 are connected with outlet pipe 35; The airtight respectively backwater ring 34 that is connected with on the side walls of middle part in the water ladle shell 32, the first half of this backwater ring 34 is equipped with the annular backwater bar of semicircle shape; Be fixed with a pair of water holding ring 33 that is positioned under the intake pipe 30 on the blower fan axle 5 between the backwater ring 34, the outward flanging of the edge symmetry of this water holding ring 33 and covered above-mentioned backwater ring 34.
During use, cooling water flows into water ladle shell 32 through inlet valve 31 and intake pipe 30, and directly drops on the blower fan axle 5, and it is cooled off; The part of the current after the heat absorption directly falls to the bottom of water ladle shell 32, and through outlet pipe 35 outflows, another part is under the effect of the rotary centrifugal force of blower fan axle 5, after being dished out along two water holding rings 33, flow to the bottom of water ladle shell 32 again by way of backwater ring 34, flow out by outlet pipe 35 at last.
Obviously, those skilled in the art can carry out various changes and modification to high-temperature blower axle cooling unit of the present utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
