Problems solved by technology

Although aluminum has good ductility, its hardness is low. During the long-term use of the aluminum ultrafiltration membrane stripping device, it is easy to cause damage to the inner thread of the ultrafiltration membrane stripping device, shorten the service life of the ultrafiltration membrane stripping device, and increase production. cost, lower product quality
If the material of the demoulding device is stainless steel, the heat dissipation is poor, resulting in insufficient heat dissipation during the curing process of the adhesive; before installing the demoulding device, it is necessary to manually apply butter, because the demoulding surface is not smooth after the demoulding device is removed due to manual smearing; the demoulding device is removed The process requires external force to disassemble the demoulding device, which may easily lead to scratches on the contact surface between the ultrafiltration membrane and the demoulding device, affecting the appearance

Embodiment 1

[0021] Embodiment 1 of the present invention: an ultrafiltration membrane demoulding device, comprising a stripper body 4, one side of the stripper body 4 is provided with a glue injection hole 1 and more than two screw trays 2, and the other side of the stripper body 4 is provided with a stripper Mold protective cover3.

[0022] The mold release protective cover 3 is a hollow ring.

[0023] Internal threads are provided in the screw tray 2, and the screw tray 2 is made of stainless steel. Compared with aluminum, stainless steel has higher hardness, is not easy to wear, and is easy to replace after wear, which greatly prolongs the service life of the demoulding device.

[0024] The ultrafiltration membrane demoulding method includes a demoulding body 4, one side of the demoulding body 4 is provided with a glue injection hole 1 and more than 2 screw trays 2, and the other side of the demoulding body 4 is provided with a demoulding protective cover 3, and the demoulding When th...

Embodiment 2

[0029] Embodiment 2 of the present invention: an ultrafiltration membrane demoulding device, comprising a stripper body 4, one side of the stripper body 4 is provided with a glue injection hole 1 and more than two screw trays 2, and the other side of the stripper body 4 is provided with a stripper Mold protective cover3.

[0030] The mold release protective cover 3 is a hollow ring.

[0031] There are internal threads in the screw tray 2, and the number of the screw trays 2 is preferably 4. The screw tray 2 is made of stainless steel. Compared with aluminum, stainless steel has higher hardness, is not easy to wear, and is easy to replace after wear. The service life of the demoulding device is greatly extended.

Abstract

The invention discloses an ultrafiltration membrane demoulding method and device. The ultrafiltration membrane demoulding device comprises a demoulding plate body (4), a glue injection hole (1) and more than two screw trays (2) are arranged on one side of the demoulding plate body (4), a demoulding protective sleeve (3) is arranged on the other side of the demoulding plate body (4), thrust acts onthe demoulding protective sleeve (3) during demoulding, the demoulding plate body (4) is propped open, and the demoulding device is separated from a membrane shell. The main body of the demolding device is made of aluminum, the remarkable advantages of light weight and good heat dissipation performance of the ultrafiltration membrane demolding device are kept, meanwhile, the stainless steel screwtray and the protective sleeve are adopted, the service life of the ultrafiltration membrane demolding device is prolonged, the production cost is reduced, and the product quality is further improved.

Description

technical field [0001] The invention relates to an ultrafiltration membrane demoulding method and device, and belongs to the technical field of ultrafiltration membrane demoulding. Background technique [0002] Ultrafiltration membrane demoulding device, in the production process of ultrafiltration membrane modules, both ends of the hollow fiber ultrafiltration membrane need to be cast and encapsulated in epoxy resin or polyurethane adhesive. After the adhesive is poured, remove the demoulding devices at both ends of the ultrafiltration membrane after the adhesive is completely cured. Because the density of aluminum is very small, only 2.7g / cm 3 , and the thermal conductivity of aluminum is 237W / mK, which is a good conductor of heat and a good heat dissipation material. In addition, aluminum has certain corrosion resistance, so most ultrafiltration membrane demoulding devices are made of aluminum. Although aluminum has good ductility, its hardness is low. During the long-t...
