Description

Technical Field

[0001] The invention relates to the field of roll-type membrane separator production equipment, and in particular to an organic gas permeation membrane roll device. Background Art

[0002] Gas membrane separation is a key component of membrane separation technology, gradually replacing many traditional gas separation processes with its economical and efficient features. Membranes are materials with selective separation capabilities. Gas membrane separation uses the partial pressure difference of gases across the membrane as the driving force. It utilizes a polymer film to selectively "filter" the feed gas to achieve separation. Spiral-wound membrane separators are made of a flat membrane. Three sides of the membrane are sealed to form a membrane bag with one side open. The open side of the bag is bonded and fixed to the outside of a central tube densely packed with holes. The bag is then wound around the central tube to form a spiral-wound membrane separator. Because the central tube of traditional spiral-wound membrane separators lacks spiral baffles, the membrane bag is wound parallel to the outer circumference of the central tube. However, for new spiral-wound membrane separators that incorporate spiral baffles to mitigate pressure drop in the direction of gas flow, existing membrane winding equipment cannot compress the membrane bag along the spiral direction of the baffles. The compression structure cannot roll along the baffle extension direction, resulting in insufficient packing density of the membrane bag in the gas separation channel to meet filtration requirements and poor product separation performance. Summary of the Invention

[0003] In order to solve the above problems, the present invention provides an organic gas permeable membrane roll device.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

A vertically extending central shaft 609 is fixed to the center of the mounting plate 601. A rocker arm 608 is rotatably fitted on the outside of the central shaft 609 through a bearing. Both ends of the rocker arm 608 extend to the ends of the two groups of arms 607 away from the auxiliary shaft 606. A positioning groove 607a extending along its length is vertically penetrated at the ends of the arms 607 away from the auxiliary shaft 606. Two groups of positioning posts 608a are fixed to both ends of the rocker arm 608 and are respectively inserted into the two groups of positioning grooves 607a. The positioning groove 607a is slidably matched, and the central shaft 609 supports the rocker arm 608 to cooperate with the positioning column 608a to realize the synchronous rotation of the two groups of support arms 607, and then the two groups of support arms 607 are linked to the two groups of auxiliary shafts 606, so that when one group of groove wheels 603a rotates along the extension direction of the baffle 201, the rocker arm 608 can cooperate with the two groups of support arms 607 to realize the synchronous rotation of the two groups of groove wheels 603a and the two groups of pressure rollers 605a, thereby keeping the two groups of pressure rollers 605a always in the direction of extension of the baffle 201 to roll the film bag 4;

A restraining cylinder 304 is passed through the middle of the top of the rotating ear 303. The restraining cylinder 304 and the rotating ear 303 are rotated through a thrust bearing to ensure that the restraining cylinder 304 can rotate in the middle of the rotating ear 303. The conical plug 305 that extends into the inner side of the end of the center tube 2 is fixed to the end of the constriction tube 304 near the center tube 2. The conical plug 305 improves the tightness of the end of the constriction tube 304 against the center tube 2. A hexagonal transmission hole 306 that passes through the plug 305 is penetrated in the middle of the constriction tube 304. The drive assembly 5 includes an electric motor 502 fixed to the outside of the support bracket 8.

The two ends of the screw 307 pass through the sliding frame 301 and are fixed with two groups of knobs 307b. The two groups of external threads 307a with opposite rotation directions are used to drive the two groups of sliders 302 to slide in opposite directions, and then the spacing between the two groups of sliders 302 can be adjusted, which is convenient for disassembly and assembly of the central tube 2 and for clamping and locking central tube 2 products of different lengths.
