Description

Technical Field

[0001] The present invention relates to the field of reaction kettles, and more specifically, to an efficient reaction kettle for chemical production. Background Art

[0002] Polyester resin can be used as basic materials such as paints and coatings. Its raw materials are mainly polyols and polyacids. The polyacids are powders or crystals. The most commonly used alcohol is neopentyl glycol. Generally, a reaction kettle capable of stirring is used for production. Since the polyacids are powders or crystals, they cannot be mixed with the liquid in time when added to the reaction kettle, which will lead to insufficient reaction. Therefore, sufficient stirring is required to mix evenly.

[0003] For example, a reaction kettle for manufacturing a formaldehyde - acetal insulation paint intermediate resin and its usage method disclosed in Patent CN115837252B. The powder material is added through a feeding port and falls onto a sieve tray. The sieve tray can move up and down reciprocally, which can evenly put the powder material into the reaction kettle. At the same time, the scraper rotates and can quickly send the powder material into the reaction kettle. Compared with the traditional reaction kettle that directly inputs the powder material, this reaction kettle can greatly reduce the formation of powder agglomerates. However, in actual use, its structure has certain defects. Combining with the prior art, the feeding port of the powder material is arranged on one side of the center of the reaction kettle. When the powder material is put in, it will concentrate on one side of the sieve tray. Even through the rotation of the scraper, most of the powder material still falls within the range with the feeding port as the radius, and the spreading range of the material cannot be well expanded, so it needs to be improved.

[0037] More specifically, Figure 2 , Figure 10As shown, the stirring structure 700 is installed on the stirring shaft 300, and a push seat 710 is provided on the stirring structure 700. The push rod 620 is located on the moving trajectory of the push seat 710, so that the push seat will contact the push rod when it moves to the preset position and push the push rod; when the push seat rotates to push the push rod, it drives the baffle to rotate, so that the second discharge hole and the first discharge hole are correspondingly connected, so that the materials in all the first discharge holes are discharged synchronously; when the push rod moves to the edge position of the bayonet, the movement of the push rod is blocked, and the push seat continues to move to disengage from the push rod, and the baffle is reset to the position blocking the first discharge hole, and then the material is filled into the first discharge hole when the stirring structure pushes the material, preparing for the next round of feeding.

[0038] Furthermore, a first flange is fixedly provided on the outer side of the top of the material tray, the outer diameter of the material tray is adapted to the top inner diameter of the kettle body, the first flange corresponds to the second flange on the kettle body and the cover body, and the first flange is clamped and installed between the two second flanges, so that the material tray is effectively installed and fixed to adapt to the overall structure of the reactor and facilitate assembly.

[0039] Furthermore, if Figure 7 , Figure 8 As shown, a support column 517 is fixedly provided at the center of the material tray 510, the bottom end of the support column 517 protrudes from the bottom surface of the material tray 510, and a circular limiting plate 518 is fixedly provided at the top of the support column 517. A first through hole penetrating the bottom surface of the material tray is provided at the center of the limiting plate, and the shaft of the stirring shaft passes through the material box through the first through hole; Figure 9 As shown, a second through hole 640 is provided in the middle of the baffle 600, and the aperture of the second through hole 640 is adapted to the diameter of the support column 517.

A circular second guide hole 530 is formed between the inner ring of the disc cover 520 and the limit plate 518; the connecting frame 720 of the stirring structure 700 extends out of the material box 500 through the second guide hole 530 and is connected to the shaft of the stirring shaft 300; this structural design can shield the top of the material disc to a certain extent and reduce the lifting of powder particles;

[0041] Furthermore, a plurality of reinforcing rib groups are fixedly arranged on the outer wall of the support ring and are distributed in a circumferential array around the center of the support ring. One reinforcing rib group includes two reinforcing ribs. The top surface of the reinforcing rib is provided with a first threaded hole, and a plurality of first through holes are correspondingly arranged at the edge of the disc cover. The disc cover is fixedly installed on the support ring through bolts. Among them, reinforcing ribs are fixedly arranged on both outer walls of the bayonet. On the one hand, the structural strength of the bayonet part can be enhanced, and on the other hand, the contact area with the push rod can be increased to effectively block the push rod.

[0042] Furthermore, a jack is arranged on the top side wall of the vertical plate, and a second threaded hole communicating with the jack is arranged on the top surface of the vertical plate. A third threaded hole is arranged on the side wall of one end of the push rod. The push rod is inserted into the jack and is connected through a pin inserted into the second threaded hole and the third threaded hole. The disassembly and assembly structure is adopted to ensure that the vertical plate smoothly passes through the first guiding hole, thus ensuring the smooth construction of the whole, and further limiting the rotational swing of the baffle to realize the alignment and conduction of the first blanking hole and the second blanking hole.

[0043] As Figures 7 to 9 shown, a first hanging ear 650 is fixedly arranged at one end of the push rod 620 close to the chute 512, and a second hanging ear 519 is fixedly arranged on the outer wall of the support ring 511. The second hanging ear is located on the upstream side of the bayonet. A tension spring 800 is connected between the first hanging ear 650 and the second hanging ear 519 to provide a restoring elastic force for the baffle, which can not only meet the requirement of the stirring structure to push the baffle to move, but also enable the baffle to be smoothly reset after the stirring structure is separated.

[0044] Furthermore, as Figures 10 to 12 shown, the stirring structure 700 includes a top pushing seat 710, a connecting frame 720 and a scraping plate 730. One end of the top surface of the scraping plate 730 is fixedly provided with a support cylinder 731, and a clamping plate 732 is arranged outside the end of the support cylinder 731. A clamping groove 733 is formed between the clamping plate 732 and the end of the support cylinder 731. The connecting frame 720 includes a collar 721 and an L-shaped hook 722 fixedly arranged at the bottom of the outer wall of the collar.

The bottom surface of the scraping plate slides and abuts against the inner wall of the bottom of the material tray for leveling the powder. The top pushing seat 710 is rotatably installed at the support cylinder 731 and provides a supporting force through a torsion spring 740. The top pushing seat, the connecting frame and the scraping plate are in an assembled matching structure, which is convenient for the processing and production of each structural component and also convenient for the overall construction.

[0045] When the pushing seat rotates to push the push rod, under the action of the torsion spring, the pushing seat maintains the pushing state, overcomes the elastic force of the tension spring, pushes the push rod, and rotates the baffle to a preset position; when the push rod moves to the edge position of the bayonet, the movement of the push rod is blocked, and the pushing seat continues to move, overcoming the elastic force of the torsion spring until it disengages from the push rod; the baffle is reset under the elastic force of the tension spring and maintains the position of blocking the first blanking hole; through the cooperation between the tension spring and the torsion spring, it meets the requirement that the pushing seat can overcome the elastic force of the tension spring when pushing the push rod, so that the baffle rotates by the required angle; when the push rod abuts against the edge of the bayonet and cannot move forward, at this time the pushing seat continues to move forward, then overcomes the elastic force of the torsion spring, makes the pushing seat rotate by a preset angle until it disengages from the push rod, realizing separation; and the baffle is reset under the elastic force of the tension spring and returns to the position of blocking the first blanking hole. After the stirring structure runs for one week, the above actions are repeated again to realize cyclic and effective feeding actions.

[0046] Further, the pushing seat 710 includes a sleeve 711 with one end blocked. A stop block 712 is fixedly arranged on the end face of the blocked end of the sleeve 711. The stop block is in an L-shaped structure, and the inner side of the corner is in an arc-shaped structure and is adapted to the diameter of the push rod, ensuring that the push rod can be effectively pushed and also realizing smooth disengagement from the push rod part after its selection.

[0047] An insert bar 713 is fixedly arranged inside the sleeve 711. A first card slot 714 for clamping one end of the torsion spring is arranged on the insert bar 713; a second card slot 734 for clamping the other end of the torsion spring 740 is arranged at the open end of the support cylinder 731; a guiding groove 735 in a closed loop around the center is arranged on the outer wall of the support cylinder 731. The inner diameter of the sleeve 711 is adapted to the outer diameter of the support cylinder 731. At least one guiding bolt 750 is correspondingly installed on the side wall of the sleeve 711. The side wall of the end of the guiding bolt away from the head is a smooth surface and the diameter is adapted to the width of the guiding groove. The sleeve 711 is rotationally installed at the end of the support cylinder 731 through the guiding bolt 750. The torsion spring 740 is installed inside the support cylinder 731 to provide a supporting force for the pushing seat; the overall structure is an assembled structure, which is convenient for the processing and production of each structural component and also convenient for overall assembly.

[0048] Further, a scraping bar 736 is fixedly arranged on one side of the scraping plate 730 close to the rotation direction. The scraping bar is inclined towards one side compared with the scraping plate. The scraping bar slides while abutting against the top surface of the material tray, and the end of the scraping bar slides while abutting against the inner wall of the support ring; when the baffle rotates with the stirring structure to the position where the second blanking hole corresponds to the first blanking hole, there is no first blanking hole in the area range between the scraping bar and the scraping plate at this time; this structural limitation ensures that in each rotation process, before the baffle moves to the position where the second blanking hole is aligned with the first blanking hole and conducts, the first blanking hole is filled with materials, further meeting the requirement of multi-point material feeding.
