Description

TECHNICAL FIELD

[0001] The utility model relates to the field of film equipment end sealing pouring technology, more specifically to a kind of glue injection assembly for hollow fiber membrane bundle end sealing pouring in columnar membrane module. BACKGROUND

[0002] Hollow fiber membrane bundle is the core of columnar membrane module, which is composed of thousands of membrane filaments and two end sealing blocks, the sealing block is formed by sealing pouring process using glue injection device, the membrane filaments and the upper and lower end covers of columnar membrane module form a whole through the sealing block, ensuring the structural stability and sealing.

[0003] The glue injection assembly is an important component of the glue injection device, which includes a glue injection cover with a glue injection hole. The glue injection hole guides the pouring material to the inside of the glue injection cover during the end sealing pouring process and fills the space around the membrane filament end, so that the pouring material can solidify according to the expected shape, ensuring that the shape of the formed sealing block matches the overall design of the upper and lower end covers of the columnar membrane module. The glue injection cover also protects the membrane filaments during the end sealing pouring process, preventing foreign matter from entering the combined area of the membrane filaments and the pouring material.

[0004] The inner wall of the traditional glue injection cover usually has a release layer to ensure that the sealing block is formed after glue injection, reducing adhesion during the release process, thereby protecting the structural integrity and ensuring smooth release. However, butter is often used as the release layer, which can easily be carried out to the outside space during the release of the sealing block, resulting in contamination of the operator's body surface and the surrounding environment, and is difficult to clean, seriously affecting the operation and polluting the working environment. In addition, the glue injection hole on the traditional glue injection cover is usually only one, causing the glue liquid to be unable to evenly fill the space around the membrane filament end during glue injection, making the shape of the sealing block unable to match the shape of the upper and lower end covers of the columnar membrane module, ultimately affecting the end sealing quality. At the same time, it also leads to a long glue injection time and low efficiency. UTILITY MODEL CONTENTS

[0005] In view of the above situation, in order to overcome the problem that the release layer of the glue injection cover of the existing glue injection assembly is butter, which is easily carried out to the outside space during the release of the sealing block, seriously affecting the operation and polluting the working environment, and cannot be reused, and the number of glue injection holes is single, resulting in uneven glue injection, affecting the fit of the sealing block and the upper and lower end covers of the columnar membrane module, and causing long glue injection time and low efficiency, the purpose of the utility model is to provide a release layer structure inside the glue injection cover, which is stable, ensuring a clean environment and smooth operation during the release of the sealing block, and can be reused. At the same time, the formed sealing block can better fit the upper and lower end covers of the columnar membrane module, and the glue injection time is shortened, improving the efficiency.

[0006] In order to achieve the above object, the technical solution of the utility model is:

[0007] A glue injection assembly for the end sealing pouring of hollow fiber membrane bundles in a column type membrane module, which comprises a glue injection cover and a glue injection base, a glue injection cavity is formed in the top of the glue injection cover, the glue injection base is arranged at the bottom of the glue injection cavity, a release layer is arranged on the inner wall of the glue injection cavity, the release layer is Teflon, a plurality of glue injection holes are formed in the glue injection cavity, each glue injection hole is communicated with the bottom of the glue injection cover, and each glue injection hole is arranged on the circumference of the glue injection base.

[0008] Preferably, the number of glue injection holes is three.

[0009] Preferably, a step position is formed on the inner side wall of the glue injection cavity.

[0010] Preferably, the inner side wall of the glue injection cavity below the step position is a slope.

[0011] Preferably, a mounting limiting groove is formed in the bottom of the glue injection cover.

[0012] Preferably, a positioning hole is further formed in the glue injection cavity, the positioning hole is communicated with the bottom of the glue injection cover, the glue injection base is opposite to the positioning hole, and the glue injection base is fixed by a positioning bolt penetrating through the positioning hole.

[0013] Preferably, the shape of the glue injection base is a cylinder.
