Stretching device with clamping function for ultrafiltration membrane production

Abstract

The invention discloses a stretching device with a clamping function for ultrafiltration membrane production, and relates to the technical field of ultrafiltration membrane production. The fixing frames are arranged on the front side and the rear side above the bottom plate. The right sides of the fixing frames incline towards the front side and the rear side of the bottom plate. The belt conveyors are embedded in the fixing frames on the front side and the rear side. An output shaft of the driving motor is connected with the rear end of the supporting roller; a side plate on one side of the clamping frame is fixed to the outer belt faces of conveying belts of the two belt conveyors. The electric push rod is fixed on a side plate on one side, far away from the belt conveyor, of the clamping frame; the clamping plates are fixed on piston rods of the electric push rods; the control switch is fixed on a side plate on one side of the clamping frame; the supporting rods are fixed to the left and right sides of the upper side wall of the vertical plate on one side of the fixing frame. The elastic rod is fixed on one side wall of the upper end of the supporting rod; the adjusting mechanism is embedded in the bottom plate; the connecting mechanisms are arranged in the left side and the right side of the bottom plate, the two sides of the film can be clamped, conveying and stretching are conducted in the clamping process, operation is easy, and the stretching requirement can be met.

Description

technical field [0001] The invention relates to the technical field of ultrafiltration membrane production, in particular to a stretching device with a clamping function for ultrafiltration membrane production. Background technique [0002] Ultrafiltration membrane is a microporous filtration membrane with a constant pore size and a rated pore size below 0.01 microns.

[0002] Ultrafiltration membrane is a microporous filtration membrane with a constant pore size and a rated pore size below 0.01 microns. Appropriate pressure is applied to one side of the membrane to screen out solute molecules smaller than the pore size. The ultrafiltration membrane screening process , with the pressure difference on both sides of the membrane as the driving force, and the ultrafiltration membrane as the filter medium, under a certain pressure, when the stock solution flows through the surface of the membrane, many small micropores densely covered on the surface of the ultrafiltration membrane only allow water and small molecules The substance passes through and becomes the permeate, while the substance in the original solution whose volume is larger than the micropore diameter of the membrane surface is trapped on the liquid inlet side of the membrane and becomes a concentrated solution, thus realizing the purpose of purifying, separating and concentrating the original solution. In the prior art The stretching of the ultrafiltration membrane is usually stretched by longitudinal or transverse stretching machine, and the process is generally unwinding, deoiling, longitudinal or transverse stretching, winding, longitudinal or transverse stretching, which is easy to break when the distance is long Film, the structure of the current film stretching device is relatively complicated, it is not easy to operate, and it does not have the clamping function, so it cannot meet the requirements of film stretching
