Description
Technical Field
The utility model belongs to the splitter field relates to a device that is used for preventing on the membrane separation equipment that the material from blockking up the membrane, concretely relates to whirl falls stifled device.
Background
In modern industrial production, membrane separation processes have emerged in recent decades. The membrane is called separation membrane or molecular sieve. Is the process of separating large particle or large molecule matter from small particle or small molecule matter. The process solves a plurality of separation problems and greatly improves the economic benefit. However, this technique also suffers from the problem of clogging of the membrane. Because of the clogging of the membrane, not only the production efficiency is reduced, but also the damage rate of the membrane is increased, affecting the service life of the membrane, thereby increasing the production cost.
The reason for the membrane blockage is that at the front side of the membrane, because small particles or small molecules permeate the membrane and enter the other side, large particles or large molecules are gathered in front of the membrane, the concentration of the large particles or large molecules at the front side of the membrane is continuously increased along with the advance of separation, and in addition, positive pressure is applied, so the large particles or large molecules are tightly attached to the surface layer of the membrane, and the small particles or small molecules are blocked from passing through.
Therefore, there is an urgent need for a device that can reduce the concentration of large particles or large molecules on the front side of the membrane and increase the concentration of small particles or small molecules to improve the separation efficiency.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a simple structure, convenient to use, reduce the jam of membrane, promote separation efficiency's whirl and fall stifled device.
In order to realize the purpose, the technical scheme of the utility model is that: the cyclone blockage reducing device comprises a propeller support, wherein the propeller support is fixedly arranged in membrane separation equipment; the membrane separation equipment is characterized in that a plurality of propellers are uniformly arranged on the propeller support, the propellers are vertically and uniformly distributed in front of a separation membrane in the membrane separation equipment, and the propellers are controlled by the power transmission driving device and rotate in the same direction.
Further, the power transmission driving device comprises a power transmission shaft, a transmission wheel and a transmission chain; the power transmission shaft is driven by a motor and is in driving connection with the transmission wheel through a transmission chain; the driving wheel is arranged above the propeller bracket; the propeller is arranged below the propeller support and is connected with the driving wheel through a rotating shaft.
Furthermore, the distance between the propeller and the separation membrane is 5-10 mm, so that the separation efficiency is greatly improved.
The utility model discloses stifled device is fallen to whirl has following beneficial effect:
1. the utility model discloses stifled device setting is fallen in the place ahead of separation membrane to the whirl, makes it produce the whirl on the separation membrane through the same direction rotation of a plurality of screw. The cyclone has two functions, one is to form entrainment on the surface layer of the separation membrane and to absorb large particles or macromolecular substances from the surface layer of the separation membrane; the other is to reduce the concentration of large particles or macromolecular substances and increase the concentration of small particles or small molecular substances above the separation membrane. The two effects further reduce the blockage of the separation membrane and improve the separation efficiency.
2. The utility model discloses the vortex falls the screw that stifled device set up and the distance between the separation membrane is limited to 5 ~ 10mm, makes it promote separation efficiency widely.

Detailed Description
For the purpose of explaining the technical content and the structural features of the cyclone blockage reducing device of the present invention in detail, the following description is further made in conjunction with the embodiments and the accompanying drawings.
As shown in fig. 1 and 2, the cyclone blockage reducing device of the present invention comprises a propeller support 5 and a power transmission driving device, wherein the propeller support 5 is fixed inside a membrane separation device 1; the power transmission driving device comprises a power transmission shaft 2, a transmission wheel 4 and a transmission chain 3; the power transmission shaft 2 is driven by a motor, transmission teeth matched with the transmission chain 3 are arranged on the power transmission shaft 2, and the power transmission shaft 2 is in driving connection with the transmission wheel 4 through the transmission chain 3; the motor drives the power transmission shaft 2 to rotate, so as to drive all the transmission wheels 4 to rotate along the same direction. A plurality of propellers 6 are uniformly arranged on the propeller support 5, a driving wheel 4 is arranged above each propeller 6, the propellers 6 are vertically and uniformly distributed in front of a separation membrane 7 in the membrane separation equipment 1, and the driving wheels 4 are arranged above the propeller support 5; the propeller 6 is arranged below the propeller support 5, and the propeller 6 is connected with the driving wheel 4 through a rotating shaft.
Preferably, the distance between the propeller 6 and the separation membrane 7 is 5-10 mm, so that the separation efficiency is greatly improved.
In the membrane separation device 1, a mixture 8 to be separated is arranged above a separation membrane 7, and separated small particles or small molecular substances 9 are arranged below the separation membrane 7.
When the membrane separation equipment 1 starts to operate, the motor drives the power transmission shaft 2 to rotate, the power transmission shaft 2 drives the transmission chain 3, and the transmission chain 3 drives all the propellers 6 to rotate through the transmission wheel 4. When all propellers 6 are rotatory, mixture 8 above the separation membrane 7 begins to rotate, produce a vortex, the large granule or the macromolecule thing on entrainment membrane top layer leaves the separation membrane 7 surface, and tiny particle or micromolecule thing enter into the separation membrane 7 below simultaneously, thereby reach the concentration that the large granule or macromolecule thing gathering, reduction large granule or macromolecule thing are reduced on separation membrane 7 top layer, thereby increase tiny particle or micromolecule thing concentration, reduce the jam of separation membrane 7, promote separation efficiency.
