Description

Technical fields:

[0001] This utility model relates to the technical field of alkalization reaction vessel, and more specifically to an alkalization reaction device for gel-based strong base anion exchange resin. Background technology:

[0002] Gel-type strong-base anion exchange resin is a polymer material based on styrene-divinylbenzene copolymer, which is formed by introducing quaternary ammonium groups (such as -N(CH3)2) into the resin. ) The presence of OH radicals imparts a strong basic ion exchange function to the resin. Therefore, an alkalization reaction is required during the preparation of gel-based strong basic anion exchange resins. This alkalization reaction takes place within an alkalization reactor. The existing alkalization reactor has an observation port on its lid, inside which is a glass observation cover. Due to space limitations and height restrictions at the observation port, bolted connections are not feasible. Therefore, multiple snap-fit ​​fasteners are used for connection. These fasteners consist of two sets of clamping components, locked together by bolts and nuts. Each fastener also has a bolt structure, resulting in a large number of fasteners and cumbersome installation and disassembly of the observation cover. Therefore, a structure that ensures effective connection and convenient installation and disassembly is needed. Utility model content:

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an alkalization reaction device for gel-based strong base anion exchange resin. The observation cover on the reactor lid of the alkalization reaction device is installed and connected by a fixed buckle and several bolts, which is convenient for installation and disassembly, and can effectively ensure a sealed connection.

[0004] An alkalization reaction apparatus for a gel-based strong-base anion exchange resin includes an alkalization vessel, which consists of a vessel body and a vessel lid. The top of the vessel lid has a central interface connected to a stirring motor. An L-shaped, inclined observation interface is formed on one side of the vessel lid near the central interface. A conical observation cover is inserted into the observation interface. A stepped observation hole is formed inside the observation cover. A transparent protective glass is inserted into the observation hole, and the protective glass is clamped and fixed between the stepped surface of the observation hole and an internally threaded collar. The internally threaded collar is screwed and fixed inside the observation cover. The apparatus is characterized by: an L-shaped connecting sleeve forming the outer ring at the lower end of the observation cover, with a circular rubber sealing ring inserted on the connecting sleeve; and several slots connected to the connecting sleeve forming on the outer wall of the observation cover.

[0005] A number of fixed fasteners with a "C"-shaped cross-section and evenly distributed in a ring are sleeved outside the outer ring of the observation cover. The lower end of the fixed fastener is buckled on the outer ring of the observation interface; a limiting insertion plate is formed on the fixed fastener, and the limiting insertion plate abuts against the upper end surface of the observation interface and is inserted into the slot of the observation cover; a number of support ears evenly distributed in a ring are formed on the outer ring of the observation cover. The support ears are located between the fixed fasteners and are screwed with fastening bolts. The end of the fastening bolt presses against the upper end surface of the observation interface. The upper end surface of the rubber sealing ring presses against the limiting insertion plate, and the outer wall of the rubber sealing ring presses against the inner wall of the observation interface.

[0006] Preferably, the central axis of the observation interface on the kettle cover coincides with the central axis of the observation cover;

[0007] The number of the fixed fasteners is greater than the number of the fastening bolts.

[0008] Preferably, the observation interface on the kettle cover includes an inclined and cylindrically ring-shaped connection interface. A retaining ring perpendicular to the connection interface is formed at the entrance of the connection interface. A conical rib ring is formed between the lower end surface of the retaining ring and the outer wall of the connection interface. A number of positioning slots are formed on the rib ring. The lower end of the fixed fastener is inserted into the positioning slot and presses against the retaining ring.

[0009] Preferably, the positioning slots are evenly distributed in a ring around the central axis of the observation interface, and the number and width of the positioning slots are respectively equal to the number and width of the fixed fasteners.

[0019] Example: See Figures 1 to 4 As shown, for the alkalization reaction device of gel strong-base anion exchange resin, the alkalization reaction device includes an alkalization kettle, and the alkalization kettle consists of a kettle body and a kettle cover 1. The top of the kettle cover 1 is provided with a central interface 11 connected to a stirring motor. On the kettle cover 1 on one side of the central interface 11, an observation interface 12 with an L-shaped cross-section and inclined is formed. A conical observation cover 2 is inserted into the observation interface 12. A stepped observation hole 21 is formed in the observation cover 2. A transparent protective glass 3 is inserted into the observation hole 21. The protective glass 3 is clamped and fixed between the stepped surface of the observation hole 21 and the internal thread sleeve 4. The internal thread sleeve 4 is screwed and fixed in the observation cover 2; an L-shaped connecting seat sleeve 22 is formed on the outer circle at the lower end of the observation cover 2. A circular rubber sealing ring 6 is inserted into the connecting seat sleeve 22; a plurality of slots 23 communicating with the connecting seat sleeve 22 are formed on the outer wall of the observation cover 2.

[0020] A plurality of fixed buckles 5 with a "匚"-shaped cross-section and evenly distributed in a ring are sleeved on the outer circle of the observation cover 2. The lower end of the fixed buckle 5 is buckled on the outer circle of the observation interface 12; a limit insertion plate 51 is formed on the fixed buckle 5. The limit insertion plate 51 abuts against the upper end surface of the observation interface 12 and is inserted into the slot 23 of the observation cover 2; a plurality of support ears 24 evenly distributed in a ring are formed on the outer circle of the observation cover 2. The support ears 24 are located between the fixed buckles 5 and are screwed with tightening bolts 7. The end of the tightening bolt 7 presses against the upper end surface of the observation interface 12. The upper end surface of the rubber sealing ring 6 presses against the limit insertion plate 51, and the outer wall of the rubber sealing ring 6 presses against the inner wall of the observation interface 12.

[0021] The central axes of the observation interface 12 on the kettle cover 1 and the central axis of the observation cover 2 coincide; the number of the fixed buckles 5 is greater than the number of the tightening bolts 7.

[0022] The observation interface 12 on the kettle cover 1 includes an inclined and cylindrical ring-shaped connection interface. A retaining ring perpendicular to the connection interface is formed at the entrance of the connection interface. A conical rib ring is formed between the lower end surface of the retaining ring and the outer wall of the connection interface. A plurality of positioning slots 13 are formed on the rib ring. The lower end of the fixed buckle 5 is inserted into the positioning slot 13 and presses against the retaining ring. Based on the positioning slot 13, it is convenient for the insertion and positioning of the fixed buckle 5.

[0023] The positioning slots 13 are uniformly arranged in a ring around the central axis of the observation interface 12, and the number and width of the positioning slots 13 are equal to the number and width of the fixed buckles 5, respectively.

[0024] The inner ring at the entrance of the observation interface 12 is formed with a conical guide opening. The taper of the guide opening is equal to the cone angle of the outer wall of the observation cover 2. The guide opening facilitates the centering of the observation cover 2.

[0025] The number of fastening bolts 7 shall be at least three and not more than eight. A certain number of fastening bolts 7 are required to cooperate with the connection of the fixed buckle 5, but the number should not be too many, otherwise it will increase the trouble of installation and connection.

[0026] Working principle: This structure is an alkalization reaction device for a strong base anion exchange resin. Its technical point is mainly reflected in the snap-fit ​​connection structure on the lid of the alkalization reaction device. The snap-fit ​​connection structure is set at the observation cover 2, and the central interface 11 at the top of the lid 1 is also applicable. This application mainly describes the snap-fit ​​structure at the observation cover 2.

[0027] When installing the observation cover 2, place the observation cover 2 at the entrance of the observation interface 12, then connect the fixed buckle 5 between the observation cover 2 and the observation interface 12, and then use the locking bolt 7 to lift the observation cover 2, thereby achieving the clamping of the fixed buckle 5 on the observation cover 2 and the observation interface 12.

[0028] During the process of lifting the observation cover 2, its rubber sealing ring 6 will also move upward, but it cannot move upward due to the restriction of the upper limit plate 51 of the fixed buckle 5, which in turn compresses and expands, thus sealing the connection between the observation cover 2 and the observation interface 12 between the compressed and expanded rubber sealing ring 6.

[0029] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
