Description
Technical Field
The utility model relates to a fan installation technique, more specifically, the utility model relates to a arrange damp fan wheel dismounting device.
Background
In the production and manufacturing process of the tobacco industry, the moisture removing system has the functions of removing green miscellaneous gas of the tobacco, controlling the moisture of materials and the like. The moisture removal fan provides power in the moisture removal pipeline system, so that the effect of discharging wet green miscellaneous gas of the tobacco materials out of the production environment is achieved. Because the moisture removing fan is in a moist environment during working, the connecting point of the impeller of the moisture removing fan and the motor shaft is easy to rust, and the impeller of the moisture removing fan is difficult to repair and disassemble. At present, the impeller is disassembled mainly by utilizing a beating rod to beat a shaft of a moisture exhaust fan out of an impeller hole, so that the impeller is separated, but the operation of the mode is dangerous, and the impeller is easy to damage.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes prior art's is not enough, provides a moisture exhaust fan impeller dismounting device to expect that the dismantlement work that can solve prior art existence is dangerous, and the easy problem of damaging of impeller.
In order to solve the technical problem, the utility model adopts the following technical scheme:
a dismounting device for an impeller of a moisture-removing fan comprises an ejector rod, a fixed disc and a fixed screw;
the ejector rod is provided with a thread;
the fixed disk is provided with a screw hole matched with the mandril in a threaded manner, and the fixed disk is provided with a through hole without threads;
the fixing screws penetrate through the through holes of the fixing disc and are installed on the impeller of the moisture exhaust fan.
When the impeller needs to be disassembled, the fixing screws are firstly used for penetrating through the through holes of the fixing disc and are installed on the impeller of the moisture exhaust fan, and then the ejector rod is installed in the screw holes of the fixing disc and continuously rotates.
Along with the rotation of the ejector rod, the ejector rod penetrates through the fixed disc and the impeller to reach the moisture exhaust fan shaft, the ejector rod continues to rotate, and the moisture exhaust fan impeller is separated from the moisture exhaust fan shaft under the reaction force.
The further technical scheme is that the threads arranged on the ejector rod are trapezoidal threads;
the internal thread of the fixed disk screw hole is a trapezoidal thread.
Trapezoidal thread has profile of tooth intensity well, and the pitch diameter than ordinary screw thread is thick and have intensity, and is more wear-resisting, can bear the characteristics of great transmission power, uses trapezoidal thread can effectively avoid the impaired problem of screw thread.
The technical scheme is that the head of the ejector rod is a hexagonal head.
The hexagonal head is convenient for the ratchet to tighten or loosen the ratchet, and the use is more convenient in the disassembly operation.
The further technical proposal is that the tail part of the mandril has conicity.
The tail part of the ejector rod is provided with a taper, so that the ejector rod is convenient to position to the axis of the moisture exhaust fan.
According to a further technical scheme, the through holes formed in the fixed disc are waist-shaped holes.
The fixing screws can penetrate through the fixing disc at different positions by using the waist-shaped holes, so that the dismounting device can adapt to moisture-removing fan impellers with different sizes.
The further technical proposal is that the number of the waist-shaped holes is 4, and the waist-shaped holes are arranged on two mutually vertical diameters of the fixed disc.
Because the row's damp fan axle after rustting combines comparatively tightly with row's damp fan impeller, if will dismantle thrust and concentrate on a fixed screw and arrange damp fan impeller installation department, lead to very easily dismantling the in-process, arrange damp fan impeller and damage.
Four fixing screws are arranged on the moisture exhaust fan impeller, so that the stress of the moisture exhaust fan impeller is more uniform, and the damage in the dismounting process is avoided.
Compared with the prior art, the utility model discloses following beneficial effect has at least: the utility model discloses a through-hole that the fixed screw passed the fixed disk is installed on row's damp fan impeller, installs the ejector pin in the fixed disk screw, and constantly rotatory ejector pin makes row's damp fan impeller under reaction force with row's damp fan axle separation, has the operation safety, and is difficult to harm the effect of impeller.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
A dismounting device for a moisture-removing fan impeller comprises an ejector rod 1, a fixed disc 2 and a fixed screw 3;
the ejector rod 1 is provided with trapezoidal threads, the head of the ejector rod is a hexagonal head 11, and the tail of the ejector rod is provided with a taper;
the fixed disk 2 is provided with a screw hole 21 matched with the mandril in a threaded manner, trapezoidal threads are arranged in the screw hole 21, the fixed disk 2 is provided with a through hole 22 without threads, the shape of the through hole 22 is a waist-shaped hole, the number of the through holes is 4, and the through holes are arranged on two mutually vertical diameters of the fixed disk 2;
