Description

Dustproof device for square flat screen motor

Technical Field

The present utility model relates generally to the field of motor dust protection, and more particularly to a high square flat screen motor dust protection device.

Background

The square plansifter transmission device is a driving unit which ensures that the square plansifter transmission device runs according to a specific track, and the motor is a power source of the transmission device. In the high square flat screen practical application, motor failure is one of the main factors of transmission failure, and the main reason for motor failure is that dust enters the interior of the motor.

The motor installation mode of the square plansifter is suspension vertical installation, the motor main body is arranged in the frame, and the motor main shaft extends out of the frame flat plate and is connected with the belt wheel to provide power. In the running process of the flour mill, dust in the air is more, dust particles enter the concave cavity of the motor mounting flange plate and are collected, and no effective and feasible cleaning method exists due to the running characteristics and structural reasons of equipment. The equipment runs for a long time, dust is difficult to prevent from entering the motor spindle by the dust-proof structure of the motor, and then enters the motor bearing, so that the motor spindle bearing is ground to be dead and invalid, and motor faults are generated.

Disclosure of Invention

In order to solve the technical problems, the utility model adopts the following technical scheme: a dust-proof device for a square flat screen motor is characterized in that a motor connecting plate 2 is provided with a sleeve 3, a belt wheel 4 is of a cylindrical sectional structure with a through hole, a motor 5 main shaft is sleeved in the through hole of the belt wheel 4, the outer end face of the belt wheel 4 is provided with a groove structure, and the bottom of the belt wheel 4 extends into the sleeve 3, so that an end face annular space is formed by the sleeve 3 and the groove of the belt wheel 4.

Preferably, the motor 5 is mounted on the frame plate 1 by a motor connection plate 2.

Preferably, the sleeve 3 is made of Q235 steel.

Preferably, the pulley sleeve comprises a sealing sleeve 6, the outer side of the sealing sleeve 6 is provided with reverse threads, and a gap is sleeved between the pulley 4 and the sleeve 3.

Preferably, the external thread depth of the sealing sleeve 6 is 6mm, and an elongated bending space is formed between the sealing sleeve and the sleeve 3.

Preferably, the sealing sleeve 6 is made of Q235 steel.

The utility model has the beneficial effects that:

according to the square flat screen transmission device, when the belt wheel works, the sleeve and the sealing sleeve respectively generate air pressure negative pressure, dust is suspended outside the long and narrow space, the dust is prevented from entering the motor bearing to play a sealing role, the dust is effectively prevented from entering the motor main shaft and the shell, and the damage of the square flat screen motor is prevented.

FIG. 1 is a schematic view of the structure of the present utility model.

In the figure: 1. the frame plate, 2, the motor connecting plate, 3, the sleeve, 4, the belt pulley, 5, the motor, 6, the seal cover.

Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model. Except for this example, devices similar to the examples of the present utility model in the industry and in the field are within the scope of the present utility model.

The motor connecting plate 2 is provided with a sleeve 3 and a sealing sleeve 6, the belt pulley 4 is of a cylindrical sectional structure with a through hole, a main shaft of the motor 5 is sleeved in the through hole of the belt pulley 4, the outer end surface of the belt pulley 4 is provided with a groove structure, and the bottom of the belt pulley extends into the sleeve 3, so that an end surface annular space between the sleeve 3 and the groove of the belt pulley 4 is formed; the outside of the sealing sleeve 6 is provided with a reverse thread which is sleeved between the belt wheel 4 and the sleeve 3 to form a reasonable gap, so as to form an elongated bending space between the sealing sleeve 6 and the sleeve 3.

The sleeve 3 and the sealing sleeve 6 are made of Q235 steel; the external screw thread degree of depth of seal cover 6 is 6mm, and when the square flat screen operation of height, motor spindle drives band pulley 4 and makes rotary motion in sleeve pipe 3, and the dust suspension is outside long and narrow space, prevents to get into the dust and gets into sleeve pipe 3 because of gravity and space restriction, and seal cover 6 also can play sealed effect because of having the clearance space, effectively prevents in the dust gets into the motor cavity, reduces the motor fault rate, increases equipment life.
