Description

Mixer for sewage treatment {Mixer for sewage disposal}

This paper relates to a stirrer for sewage treatment, and in particular, a plurality of planetary gears located between a drive gear and an internal gear coupled to a rotating shaft of a motor by rotation of a powered motor is rotated and coupled thereto. By rotating the agitated body, the fluid in the sewage tank is agitated up, down, left, and right, so that there is no loss of separation of the fluid flow and vortex caused by vortex, while the component force of the fluid flow is radial and vertical flow. To minimize the use of energy by the stirrer and to prevent sludge homogenization to prevent sedimentation while pulling the wire connecting the connecting piece of the lower housing and the external winding roller. The upper and lower housings and the stirring bodies are brought into close contact with the bottom surface of the sewage tank for stable stirring. The number and relates to a support frame and base, and upper and lower housing and maintenance to withdraw the stirring member to which the outer rear support to the surface and a stirrer for sewage treatment for cleaning is to yitorok for by the loose movement of the wire.

Although the agitator installed in the conventional sewage tank is not shown, the flow of the fluid in the sewage tank is advanced only in the up and down directions because it is designed, manufactured and rotated in a fresh shape.

That is, the fluid in the sewage tank proceeds only in the up and down direction as the stirrer rotates, causing vortex due to separation of the fluid flow and vortex flow, and loss of fluid velocity, thereby using energy by the stirrer. This takes a lot of time and the problem of sedimentation occurred without sludge homogenization on the bottom surface of the sewage tank.

In particular, the conventional stirrer as described above is fixed to the bottom of the sewage tank, so when a failure occurs in the stirrer or when the stirrer is cleaned, all the fluids in the sewage tank are removed, and then the worker enters the sewage tank to repair or clean the stirrer. Because it had to be very troublesome and inconvenient.

The purpose of this article to solve and complement these conventional problems,

The fluid in the sewage tank is agitated up, down, left and right so that there is no loss that causes vortex due to separation of the fluid flow and vortex flow, while loss of fluid velocity by forming the component of the flow flow in the radial and vertical flow. While minimizing the use of energy by the stirrer and homogenizing the sludge to prevent sedimentation, the support frame, the pedestal, the upper and lower housings and the stirring bodies are floated on the water surface and drawn out to the outside for easy maintenance and cleaning. Serve the purpose.

In order to achieve the above object,

Rotating a plurality of planetary gears located between the drive gear and the internal gear coupled to the rotary shaft of the motor by the rotation of the motor is applied to rotate the operating shaft and the stirring body coupled thereto and the lower side The wire connecting the connecting piece of the housing and the external winding roller can be fixed to the bottom surface of the sewage tank or floated on the water surface by pulling and releasing the wire to achieve the purpose of this paper. do.

In order to support the wire 115 to the bottom surface of the sewage tank 119 so as not to be supported, a plurality of support rollers 117 are installed on the bottom surface of the sewage tank 119 to support the wire 115. .

The operation of this paper is as follows.

First, when an external power source is applied to the motor 101 built into the lower housing 111 through the wire 118, the motor 101 is driven to rotate the rotary shaft 102 and the drive gear 103. .

In addition, a plurality of planetary gears 104 engaged between the drive gear 103 and the internal gear 106 by the rotation of the drive gear 103 also makes an orbital motion along the internal gear 106.

That is, the rotation speed output to the rotating shaft 102 is reduced according to the orbiting motion of the planetary gears (104).

In addition, the operation shaft 107 connected to the planetary gears 104 and the connecting pin 105 by the decelerating rotation of the planetary gears 104 also performs the deceleration rotation.

In addition, the stirring body 108 coupled to the working shaft 107 also rotates the fluid in the sewage tank 119 while decelerating rotation.

That is, the stirring body 108 is manufactured in a hyperbolic symmetrical disc shape as a sealing molding material between the synthetic resin and polyurethane, and a plurality of wing feathers maintaining a constant interval on the surface thereof is integrated as shown in FIG. When 108 is rotated, the fluid in the sewage tank 119 is agitated up, down, left and right so that the separation of the fluid flow and the loss causing the vortex caused by the vortex are eliminated. To reduce the fluid velocity.

On the other hand, the usual stirring body 108 of the present proposal to maintain a stable state close to the bottom surface of the sewage tank 119 has a stable stirring action and when the maintenance or cleaning of the stirring body 108, the sewage tank 119 It floats on the surface of the water and is withdrawn to the outside.

That is, since the stirring body 108 is normally in the state of pulling the wire 115 by the external winding roller 116, the support frame 114 having the pedestal 113 is formed on the bottom surface of the sewage tank 119. Keep in close contact.

Therefore, since the lower housing 111, the upper housing 112, and the stirring body 108, which are coupled to the pedestal 113, are firmly supported as shown in FIG. 1, a smooth stirring operation can be performed in a stable state.

In addition, the wire 115 connecting the winding roller 116 and the connecting piece 110 of the lower housing 111 is closely supported by a plurality of support rollers 117 coupled to the bottom surface of the sewage tank 119. Therefore, the interference of the rotation of the stirring body 108 is not prevented.

In order to repair or clean the stirring body 108 and its accessories in the usual state, the stirring body 108 and its assemblies can be lifted and taken out.

That is, when the outer winding roller 116 is rotated to release the wire 115, the force that is in close contact with the support frame 114 to the bottom surface of the sewage tank 119 disappears, so that the sealing property between the synthetic resin and the polyurethane A stirring body 108 made of a shape member is supported from the position of FIG. 2A to the position of FIG. 2B.

When the stirring body 108 is floated on the surface as described above, the hook connected to the crane 120 outside with the ring piece 109 formed on the upper side of the stirring body 108 is hooked as shown in FIG. 108, the upper and lower housings 112 and 111 and the pedestal 113 and the support frame 114 can be lifted on the water surface.

At this time, the wire 115 connected to the connecting piece 110 of the lower housing 111 continues to loosen while helping the stirring body 108 to support its accessories.

The upper and lower housings 112 and 111 and the lifting body 108 and the support frame 114 lifted as described above are drawn out to the outside as shown in FIG. 2E to perform maintenance and cleaning.

Then, after the repair and cleaning is completed as described above, the reaction occurs by winding the winding roller 116, the stirring body 108, the upper and lower housings 112, 111 and the pedestal 113 and the support frame 114 and the like can be held in close contact with the bottom surface of the sewage tank 119.
