Description

Technical Field

[0001] This utility model relates to the field of hydroxyethyl acrylamide production, and in particular to a feeding device for hydroxyethyl acrylamide production. Background Technology

[0002] The hydroxyethyl acrylamide production unit consists of a support frame, a reaction vessel, a transmission device, and a feed frame. It is a commonly used device for stirring and producing hydroxyethyl acrylamide and is frequently seen in daily life.

[0003] Existing technologies, such as the utility model patent with publication number CN220159968U, disclose a reaction vessel employing a top cover and a reaction chamber. The feeding assembly includes a feeding section and a transmission section. The transmission section can move along its axial direction. During the movement of the transmission section, it abuts against the feeding section, and the feeding section moves along with the transmission section, allowing the feeding section to enter the interior of the reaction chamber from the top cover. The feeding section follows the transmission section along its axial direction, thereby introducing the feeding section into the reaction chamber, realizing the process of feeding the reaction raw materials into the reaction chamber. On the one hand, since the amount of raw materials fed into the reaction chamber at one time is fixed, this scheme can make the reaction process more efficient and precise. On the other hand, the feeding speed and position can be controlled by controlling the moving speed and distance of the transmission section, reducing errors and waste in the reaction process. It has high reliability and stability, improving production efficiency and quality.

[0004] The inventors discovered in daily use that in existing technologies, the feeding methods for reaction vessels are mostly manual or automated. However, both manual and automated feeding via conveyor belts require opening the reaction vessel lid. Since reaction vessels are typically sealed with multiple bolts, the bolts need to be loosened during operation, increasing the complexity of the feeding process. Furthermore, if the reaction vessel requires preheating before processing, opening the lid for feeding may lead to significant heat loss, affecting the stability of the reaction temperature and process efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies.

[0006] To solve the above technical problems, this utility model provides a feeding device for the production of hydroxyethyl acrylamide, comprising: a support frame, a reaction vessel mounted on the upper surface of the support frame, a transmission device mounted on the upper end of the reaction vessel, a feeding frame mounted on the arc surface of the reaction vessel, a connecting structure provided on the side of the feeding frame away from the reaction vessel, the connecting structure including a circular rail, the circular rail being fixedly connected to the feeding frame, a plurality of rotating rods slidably connected to the inner wall of the circular rail, a retaining ring fixedly connected to the end of the rotating rod away from the circular rail, a connecting pipe slidably connected to the inner wall of the feeding frame, a rotating ring fixedly connected to the arc surface of the connecting pipe, a plurality of retaining blocks fixedly connected to the arc surface of the rotating ring, a plurality of slots opened on the inner wall of the retaining ring, a hopper fixedly connected to the end of the connecting pipe away from the feeding frame, a plurality of connecting frames fixedly connected to the side of the hopper away from the support frame, and an inclined plate fixedly connected to the upper end of the connecting frame.

[0007] The effect achieved by the above components is as follows: when it is necessary to connect the connecting pipe to the feeding frame, the connecting pipe is pulled to move, the connecting pipe drives the hopper to move, the hopper drives the connecting frame and the inclined plate to move, the connecting pipe drives the rotating ring to move, then the connecting pipe is inserted into the feeding frame, then the rotating ring and the locking block are inserted into the locking ring, after moving to the appropriate position, the locking ring is rotated to move, the locking ring drives the rotating rod to move, the rotating rod slides on the inner wall of the circular rail, after moving to the appropriate position, the slot and the locking block are staggered, and then the locking block and the locking ring abut and fix.

[0008] Preferably, a plurality of levers are fixedly connected to the arc surface of the retaining ring, and the plurality of levers are evenly distributed on the retaining ring.

[0009] The effect achieved by the above components is that when it is necessary to rotate the retaining ring, the lever can be rotated directly, and the lever drives the retaining ring to move, making it more convenient to move the retaining ring.

[0010] Preferably, an anti-slip pad, which is a rubber pad, is fixedly connected to the side of the retaining ring near the rotating ring.

[0011] The effect achieved by the above components is that the anti-slip pad can increase the friction between the locking block and the locking ring, preventing slippage after the locking block and the locking ring are connected.

[0012] Preferably, a plurality of the card blocks are adapted to a plurality of the slots, the card ring is an iron ring, and the card block is a magnetic block.

[0013] Preferably, a stirring structure is provided on the side of the hopper away from the connecting frame. The stirring structure includes a connecting plate, which is fixedly connected to the hopper. A fixing rod is fixedly connected to the upper surface of the connecting plate. A sliding rod is fixedly connected to the upper end of the fixing rod. A support rod is movably connected to the arc surface of the sliding rod. Several positioning rods are fixedly connected to the end of the support rod near the fixing rod. Several positioning grooves are formed on the inner wall of the fixing rod. A servo motor is installed at the end of the support rod away from the fixing rod. A stirring rod is fixedly connected to the output end of the servo motor. A mobile power supply is installed at the upper end of the servo motor.

[0014] The aforementioned components achieve the following effect: When it is necessary to agitate the material in the hopper, the support rod is pulled to move, which in turn drives the servo motor to move, lifting the support rod upwards. Then, the support rod drives the positioning rod to move, separating it from the positioning slot. Next, the servo motor drives the stirring rod to move, raising the stirring rod above the hopper. Then, the support rod is rotated to move the stirring rod. After placing the stirring rod inside the hopper, the support rod is pressed down to insert the positioning rod into the positioning slot for fixation. Finally, the servo motor is started to operate, driving the stirring rod to agitate the material and prevent blockage.

[0015] Preferably, the arc surface of the support rod is fixedly connected with an anti-slip sleeve, which is a rubber sleeve.

[0016] The effect achieved by the above components is that the anti-slip sleeve can increase the friction between the hand and the support rod, preventing slippage when the support rod is pulled.

[0017] Preferably, the support rod is made of stainless steel and has an "L" shaped cross-section.

[0018] The effect achieved by the above components is that the stainless steel material can increase the service life of the support rod and prevent the support rod from rusting during use.

[0019] Compared with related technologies, the feeding device for the production of hydroxyethyl acrylamide provided by this utility model has the following advantages:

[0020] This invention provides a feeding device for the production of hydroxyethyl acrylamide. By setting up a connection structure, it addresses the common practice in the prior art of feeding reactors manually or automatically. However, both manual and automated feeding via conveyor belts require opening the reactor lid. Since reactors are typically sealed with multiple bolts, unscrewing these bolts during operation increases the complexity of the feeding process. Furthermore, if the reactor requires preheating before processing, opening the lid for feeding can lead to significant heat loss, affecting the stability of the reaction temperature and process efficiency. This device allows for convenient feeding without opening the reactor lid, reducing heat loss and improving material processing efficiency.

[0021] By incorporating a stirring structure, this design effectively and uniformly mixes the material within the hopper, preventing blockages during the feeding process. Furthermore, when material clumps, the stirring rod mechanically breaks up the clumps, ensuring smooth material transport. Attached Figure Description
