Abstract

This utility model relates to the field of sealing membrane fibers in curtain membrane modules, specifically to a device for neatly arranging and positioning membrane fibers in curtain membrane modules. In practical application, the membrane fiber clamps are first inserted into the membrane fiber clamp fixing slots. Then, the membrane fibers are placed inside the clamps, with the bottom of the fibers pressed against the membrane fiber alignment baffles to ensure consistent fiber root length. Sealing is then performed. After sealing, end caps are added to the membrane fiber clamps, and the fixing slots are removed, allowing for the operation of the next set of membrane fiber clamps.

Description

Technical Field

[0001] This utility model relates to the field of sealing membrane fibers in curtain membrane modules, specifically to a device for neatly arranging and positioning sealing membrane fibers in curtain membrane modules. Background Technology

[0002] Hollow fiber curtain membrane modules (MBR) are a new type of membrane separation technology for water treatment. They have advantages such as high water treatment efficiency, good effluent quality, and small equipment footprint. They can also achieve automatic control and operation pipelines, and are therefore widely used in wastewater treatment in municipal, printing and dyeing, chemical, power, steel, papermaking and other fields.

[0003] The existing production processes for hollow fiber membrane modules are mostly divided into two types. The membrane fibers are encapsulated in a plastic membrane shell by inserting or arranging the fibers and using encapsulating adhesive. Membrane modules produced by inserting fibers also need to undergo processes such as membrane pore plugging and end cutting and opening. Then, the permeate separated by the membrane is collected in the permeate pipe of the membrane shell for wastewater treatment.

[0004] In the production process of hollow fiber curtain membrane modules, the traditional wire insertion process is complex and inefficient. Currently, the mainstream high-efficiency production method involves neatly arranging the membrane fibers and then using a wire arrangement process to produce curtain membrane modules, which improves production efficiency. Generally, two layers of elastic adhesive are used to fix a certain number of membrane fibers in an evenly spaced row, then glued together to form sheets. These sheets are then stacked into individual membrane modules and bonded to the membrane shell for water production.

[0005] Currently available membrane modules often have uneven fiber lengths at the roots after the membrane sheets are stacked.

[0006] Uneven bonding of the upper elastic adhesive layer will affect the integrity of the membrane fiber skin layer at the bottom of the membrane shell, thus affecting the quality of the produced water; uneven bonding of the lower elastic adhesive layer will result in uneven lengths of the membrane fiber roots, reducing the water collection area of ​​the membrane shell and affecting the water production efficiency. Summary of the Invention

[0007] This invention aims to provide a device for neatly arranging, positioning, and sealing membrane filaments in a curtain-type membrane module, which can avoid the problem of uneven filament root lengths after membrane stacking. The specific solution is as follows: A device for neatly arranging, positioning, and sealing membrane filaments in a curtain-type membrane module includes a membrane placement platform. The membrane placement platform is provided with a membrane filament clamping plate fixing groove. A membrane filament clamping plate is detachably installed on the membrane filament clamping plate fixing groove. A membrane filament alignment baffle is installed on the membrane placement platform via a baffle adjusting screw.

[0008] The membrane fiber alignment baffle includes a movable part and a baffle part. The movable part has an elongated groove, and the baffle adjusting screw is disposed in the elongated groove. This configuration allows the membrane fiber alignment baffle to move a certain distance, thereby adjusting its position.

[0009] The diaphragm placement platform is equipped with an "L"-shaped baffle at one end. The "L"-shaped baffle is designed to be directly secured to the worktable.

[0010] The membrane placement platform is equipped with several membrane filament tightening and fixing posts. Because the membrane filaments are relatively long, the membrane filament tightening and fixing posts can restrict the movement space of the membrane filaments, and the two-point limiting can also better ensure the quality of sealing.

[0011] The membrane filament clamp includes several protruding frames, and the distance between two adjacent protruding frames is greater than the distance between two adjacent membrane filament tightening and fixing posts.

[0012] The membrane placement platform is equipped with membrane elevation blocks. These blocks are designed to keep the membrane fibers as flat as possible while allowing space for the elastomer adhesive to seep in, preventing the adhesive from clogging the pores.

[0013] This invention provides a device for neatly arranging, positioning, and sealing membrane fibers in a curtain-type membrane module. In practical application, the membrane fiber clamps are first inserted into their fixing slots. Then, the membrane fibers are placed within the clamps, with the bottom of the fibers pressed against the alignment baffles to ensure consistent fiber root length. Sealing is then performed. After sealing, end caps are added to the clamps, and the fixing slots are removed, allowing for the operation of the next set of clamps. Attached Figure Description

[0015] The following is combined with Figure 1-5 Further explanation: A device for neatly arranging, positioning, and sealing membrane filaments in a curtain-type membrane module includes a membrane placement platform 1, a membrane filament clamping groove 2 on the membrane placement platform 1, a membrane filament clamping plate 3 detachably installed on the membrane filament clamping groove 2, and a membrane filament alignment baffle 5 installed on the membrane placement platform 1 via a baffle adjusting screw 4.

[0016] The membrane fiber alignment baffle 5 includes a movable part and a baffle part. The movable part is provided with an elongated groove 6, and the baffle adjusting screw 4 is disposed in the elongated groove 6. Through this setting, the membrane fiber alignment baffle 5 can be moved a certain distance, thereby adjusting its position.

[0017] One end of the diaphragm placement platform 1 is equipped with an "L"-shaped baffle 7. The "L"-shaped baffle 7 is for direct clamping onto the worktable.

[0018] The membrane placement platform 1 is equipped with several membrane filament tightening and fixing posts 8. Since the membrane filaments are relatively long, the membrane filament tightening and fixing posts 8 can restrict the movement space of the membrane filaments, and the two-point limiting can also better ensure the quality of sealing.

[0019] The membrane wire clamp 3 includes several protruding frames, and the distance between two adjacent protruding frames is greater than (slightly greater than) the distance between two adjacent membrane wire tightening and fixing posts 8.

[0020] The membrane placement platform 1 is equipped with membrane elevation blocks 9. The membrane elevation blocks 9 are designed to make the membrane fibers as flat as possible, while also allowing space for the elastomer adhesive to seep down and prevent the adhesive from clogging the pores.

[0021] The operating steps of this utility model are as follows: Depending on the required production of the curtain membrane, adjust the position of the baffle adjusting screw 4, then install the membrane fiber clamp 3 on the membrane fiber clamp fixing groove 2, and then place the membrane fiber inside the membrane fiber clamp 3 (e.g. Figure 4 , Figure 5 Then, press the bottom of the membrane fiber against the membrane fiber alignment baffle 5 to ensure that the root length of the membrane fiber is consistent. Then, perform the sealing operation; after sealing, put the end cap on the membrane fiber clamp 3 and remove the membrane fiber clamp fixing groove 4, and then you can perform the operation of the next set of membrane fiber clamps 3.
