Description

Technical Field

[0001] The utility model relates to the technical field of chemical production equipment, in particular to a material transportation device for a thermal polymerization reaction outlet. Background Art

[0002] Thermal polymerization is the process by which, without the addition of an initiator, monomer molecules are heated to generate sufficient energy to initiate polymerization, resulting in the formation of a polymer. This reaction is a type of free radical polymerization, in which monomer molecules are excited to form free radicals at high temperatures, which in turn initiate a chain polymerization reaction.

[0003] After the high-temperature polymerization reaction, the materials need to be transported to the granulator for processing. Since the thermal polymerization reaction process takes a long time, the waiting time interval for a single granulator to complete its work is also very long, which is not conducive to the work efficiency in the production process. At this time, multiple reactor polymerization reaction equipment are needed to stagger feeding to ensure that the granulator can operate continuously and stably. However, the common polymerization reaction equipment itself is large in size and cannot share the same transportation line for transportation. At this time, it is necessary to switch the transportation routes of multiple feeding equipment to ensure that multiple reactor polymerization reaction equipment can stagger feeding for the granulator.

[0010] In a preferred embodiment: raising frames are installed at the lower ends of the first transport line, the second transport line and the granulation transport line. The heights of the raising frames of the first transport line and the second transport line are higher than the line switching device, and the height of the raising frame of the granulation transport line is lower than the line switching device, so that the polymer semi-finished products transported on the first transport line and the second transport line can smoothly pass through the line switching device and fall onto the granulation transport line.

[0011] In a preferred embodiment, triangular guard plates are symmetrically installed on the left and right sides of the middle of the granulation conveying line, and the protection of the triangular guard plates can reduce the risk of the polymer transported by the line switching device slipping out of the granulation conveying line.

[0016] 1. When the utility model is used, the servo motor is driven to drive the small pulley to rotate. Under the linkage of the belt, the large pulley can rotate following the small pulley. Since the outer contour lengths of the small pulley and the large pulley are different, it is convenient to control the rotation angle of the large pulley through the small pulley, and then control the switching mechanism to switch the angle between the first transport line and the second transport line, thereby cooperating with the guard plate to prevent the polymer material from slipping out of the granulation transport line.

[0017] 2. When the utility model is used, the driving device drives the limiting column on the round seat to slide along the limiting arc groove through the connecting rod, forcing the column rod to rotate on the positioning column, so that the column rod drives the guide inclined plate at the upper end of the fixed column to rotate, thereby realizing the supply of polymer materials between the first transport line-granulation transport line and the second transport line-granulation transport line to the granulator, ensuring that the granulator can work continuously and stably, and improving the work efficiency in the production process.

The raising frames 4 of the first transportation line 1 and the second transportation line 2 are higher than the line switching device 6, and the raising frame 4 of the granulation transportation line 3 is lower than the line switching device 6, so that the polymer semi-finished products transported on the first transportation line 1 and the second transportation line 2 can smoothly pass through the line switching device 6 and fall onto the granulation transportation line 3. Triangular guard plates 5 are symmetrically installed on the left and right sides of the middle of the granulation transportation line 3. The protection of the triangular guard plates 5 reduces the polymer guided by the line switching device 6 from sliding out of the granulation transportation line 3.

[0032] The line switching device 6 includes a guide slot 61, a switching mechanism 62, a driving device 63, and a fixed frame group 64.

[0034] The driving device 63 includes a servo motor 631, a small pulley 632, a large pulley 633, a belt 634 and a connecting rod 635. The servo motor 631 is fixedly mounted on the right side of the upper end of the base plate 641. The small pulley 632 is fixedly mounted on the output shaft at the left end of the servo motor 631. The connecting rod 635 is rotatably provided in the sleeve rod 646. The large pulley 633 is fixedly mounted on the right end of the connecting rod 635.

The arc-shaped limiting plates 624 are symmetrically arranged on the circumference of the round seat 621. The two arc-shaped limiting plates 624 are fixedly connected to the round seat 621 by a fixing rod 623. The column 625 is set on the upper and lower ends of the positioning column 643. The positioning plate 627 is installed, and the column 625 carries the positioning plate 627 and rotates freely on the positioning column 643. Two intersecting limit arc grooves 626 are opened on the side end of the column 625. The limit arc grooves 626 are set to slide correspondingly with the limit column 622. Two positioning holes 628 are opened on the two positioning plates 627. The positioning holes 628 are set correspondingly with the arc-shaped limit plates 624. Therefore, after the positioning column 643 slides in a directional manner in the limit arc grooves 626, the positioning holes 628 are forced to dock with the arc-shaped limit plates 624, thereby limiting the column 625 from further rotating on the positioning column 643.

[0036] The guide slot seat 61 includes a fixed column 611, a guide inclined plate 612, a guard plate 613 and a reinforcing rib 614.

Several reinforcing ribs 614 are provided between the guide inclined plate 612 and the fixed column 611. The reinforcing ribs 614 are used to ensure the stability of the guide inclined plate 612 during the feeding process.

[0037] The working principle of this utility model is:

[0038] When the present invention is used, the servo motor 631 is driven to drive the small pulley 632 to rotate, and under the linkage of the belt 634, the large pulley 633 can rotate along with the small pulley 632. Since the outer contour lengths of the small pulley 632 and the large pulley 633 are different, it is convenient to control the rotation angle of the large pulley 633 through the small pulley 632, and then control the angle switching of the switching mechanism 62 between the first transport line 1 and the second transport line 2, thereby cooperating with the guard plate 613 to prevent the polymer material from slipping out of the granulation transport line. Conveyor line 3; secondly, the large pulley 633 drives the limiting column 622 on the round seat 621 to slide along the limiting arc groove 626 through the connecting rod 635, forcing the column rod 625 to rotate on the positioning column 643, so that the column rod 625 drives the guide inclined plate 612 at the upper end of the fixed column 611 to rotate, thereby realizing the supply of polymer materials between the first transport line 1-granulation transport line 3 and the second transport line 2-granulation transport line 3 to the granulator, ensuring that the granulator can work continuously and stably, and improving the work efficiency in the production process.

[0039] The above is only a preferred specific implementation method of the present invention, but the design concept of the present invention is not limited to this.
