Description

Technical Field

[0001] This utility model relates to the technical field of feeding and output devices, and more specifically, to a quantitative feeding and output device for producing divinylbenzene. Background Technology

[0002] Divinylbenzene is produced from mixed diethylbenzene, a byproduct of the alkylation of ethylene and benzene to ethylbenzene. Divinylbenzene can be obtained by thermal dehydrogenation of the mixed diethylbenzene. In the production of divinylbenzene, quantitative feeding and material homogenization are crucial aspects affecting product quality. Existing feeding and output devices for divinylbenzene production typically rely on a single stirring structure to achieve material mixing.

[0003] For example, using a motor to directly drive the stirring paddle to rotate has the problem of insufficient homogenization effect in practical applications. Specifically, the material is only subjected to shear force in a single plane, making it difficult to form forced convection in multiple dimensions. This results in poor material mixing uniformity, easy local concentration deviation, and affects the efficiency of subsequent reactions and product purity. At the same time, traditional homogenization mechanisms are mostly fixed installations, which cannot dynamically adjust the stirring position according to the material liquid level, further limiting the improvement of homogenization effect.

[0004] Therefore, a quantitative feeding and output device for the production of divinylbenzene is proposed to address the above-mentioned problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 As attached Figures 1 to 4The illustrated quantitative feeding and output device for producing divinylbenzene includes a support frame 1, a feeding tank 2 connected to the support frame 1, and an electromagnetic feeder 5 installed at the bottom of the feeding tank 2 for quantitatively feeding and outputting the material from the feeding tank 2. It also includes a homogenizing mechanism 4, comprising a blower 41, an L-shaped connecting pipe 42 connected to the output end of the blower 41, and a telescopic pipe 43 connected to the side of the L-shaped connecting pipe 42 away from the output end of the blower 41. The blower 41 provides high-pressure air power, which passes through the L-shaped connecting pipe 42, the telescopic pipe 43, and the main shaft. Pipe 44 forms a closed air passage, transmitting power to the hollow disc block 48 and prism rods 49, providing basic motion for subsequent movements. The side of telescopic tube 43 furthest from the L-shaped connecting tube 42 is connected to the main shaft tube 44. A connecting ring block 45 is connected to the top of the outer wall of the main shaft tube 44. A rigid disc block 46 is fixedly connected to the bottom of the outer wall of the main shaft tube 44. Telescopic tube 47 is connected to the bottom of the main shaft tube 44. The end of telescopic tube 47 furthest from the main shaft tube 44 is connected to the hollow disc block 48. Two prism rods 49 are arranged in a circumferential array on the outer wall of the hollow disc block 48. Nozzles are mounted on rod 49, with the nozzles on both sides of the prismatic rod 49 being rotationally symmetrical. Two blades 410 are symmetrically mounted on the outer wall of the hollow disc block 48, and the two blades 410 are rotationally symmetrical. A spring 411 connects the hollow disc block 48 and the rigid disc block 46. A long rod 412 is fixedly connected to the top of the hollow disc block 48, and the long rod 412 is slidably connected to the inner wall of the rigid disc block 46. The blower 41 blows high-pressure air into the L-shaped connecting pipe 42, and then through the telescopic pipe 43, the main shaft pipe 44, the hollow disc block 48, the prismatic rod 49, and finally through... The liquid material is ejected from the nozzle on the prism rod 49. The symmetrical nozzle on the prism rod 49 ejects air while driving the prism rod 49 to rotate around the hollow disc block 48. The hollow disc block 48 drives the blade 410 to rotate. As the blade 410 rotates, it contacts the liquid material and moves downward, causing the telescopic tube 47 and the spring 411 to stretch. After the blower 41 is turned off, the spring 411 will drive the hollow disc block 48 and the prism rod 49 to move upward, and so on in a cycle. The support frame 1 is equipped with a lifting mechanism 3, which is used to move the homogenizing mechanism 4 up and down.

[0019] Wherein: one end of spring 411 is connected to the rigid disc block 46, and the other end of spring 411 is connected to the hollow disc block 48. A hollow T-shaped rod 413 is provided on the side of the prism rod 49 away from the hollow disc block 48. A nozzle is provided on the side of the hollow T-shaped rod 413 near the inner wall of the feeding tank 2 for spraying the side wall of the feeding tank 2 to prevent material from easily remaining on the tank wall. The lifting mechanism 3 includes a mounting plate 31, a telescopic motor 32 is fixedly connected to the mounting plate 31, a support member 33 is fixedly connected to the output shaft of the telescopic motor 32, a guide rod 34 is slidably connected to the inner wall of the support member 33, the guide rod 34 is fixedly connected to the support frame 1, a cover 35 is fixedly connected to the support member 33, and the inner wall of the cover 35 is connected to the connecting plate 31. The ring block 45 is fixedly connected, and the telescopic motor 32 is fixed on the mounting plate 31. When its output shaft extends or retracts, it drives the support 33 to slide up and down along the guide rod 34. The guide rod 34 is fixed on the support frame 1 to ensure the stability of the movement. The support 33 synchronously drives the cover 35 to rise and fall, which is used to cover the feeding tank 2 during work, and after use, the cover 35 drives the connecting ring block 45 and its lower parts to move upward for easy cleaning. The cover 35 is provided with an exhaust groove. The mounting plate 31 is fixedly connected to the support frame 1 by bolts. The L-shaped connecting pipe 42 and the telescopic pipe 43 are connected by a flange structure. The outer wall of the main shaft pipe 44 is fixed to the connecting ring block 45 by welding. The prism rod 49 and the hollow disc block 48 are integrally formed structures.

[0020] Blower 41 blows high-pressure air into L-shaped connecting pipe 42, then through telescopic pipe 43, main shaft pipe 44, hollow disc block 48, and prism rod 49, finally spraying it out through the nozzle on prism rod 49. The symmetrically rotating nozzle on prism rod 49 sprays air while driving prism rod 49 to rotate around hollow disc block 48. Hollow disc block 48 drives blade 410 to rotate. As blade 410 rotates, it contacts the liquid material and moves downward, causing telescopic pipe 47 and spring 411 to stretch. After blower 41 is turned off, spring 411 will drive hollow disc block 48 and prism rod 49 to move upward. This cycle repeats, effectively improving the homogenization of the material and enhancing the mixing uniformity. When the symmetrically rotating nozzle on prism rod 49 sprays air, the reaction force drives prism rod 49 to rotate around hollow disc block 48, simultaneously driving blade 410 to rotate. During the rotation, blade 410 forms a shearing force on the liquid material, breaking up local agglomeration or stratification of the material. When the blade 410 rotates, it comes into contact with the liquid material. The resistance of the material pushes the hollow disc block 48 downward, causing the telescopic tube 47 to stretch and the spring 411 to deform and store energy. After the blower 41 is turned off, the spring 411 elastically returns to its original position, driving the hollow disc block 48, the prism rod 49, and the blade 410 to move upward. This composite motion of "rotation + up-and-down reciprocating" acts on the material simultaneously from both horizontal and vertical directions, avoiding mixing dead zones and greatly improving homogeneity. The expandable characteristics of the telescopic tube 43 and the telescopic tube 47 provide a buffer space for the above-mentioned rotation and reciprocating motion, avoiding component wear caused by rigid connections, and adapting the equipment to materials of different viscosities.

[0021] The telescopic motor 32 is fixed on the mounting plate 31. When its output shaft extends or retracts, it drives the support member 33 to slide up and down along the guide rod 34. The guide rod 34 is fixed on the support frame 1 to ensure the stability of the movement. The support member 33 synchronously drives the cover 35 to rise and fall, which is used to cover the feeding tank 2 during work and to drive the connecting ring block 45 and its lower parts to move upward after use, which is convenient for cleaning.

[0022] The above describes the working principle of this quantitative feeding and output device for producing divinylbenzene.
