Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch processing equipment, in particular to a masterbatch crystallization drying furnace. Background Art

[0002] At present, in the production and preparation process of masterbatch, a water tank is used to cool the masterbatch bar before cutting it into pellets to form masterbatch. At this time, the masterbatch will have a certain amount of moisture and needs to be dried; or when other cooling methods are used, the masterbatch will inevitably have moisture before packaging and also needs to be dried. Therefore, drying of masterbatch is a necessary process.

[0003] The Chinese utility model patent with publication number CN216869097U discloses a uniform drying device for masterbatches, which uses a mesh conveyor belt structure to convey the masterbatches. The mesh conveyor belt structure is vibrated by a vibration motor and a vibration table to make the masterbatches flip during the conveying process. The vibration table is connected to a hot air inlet to convey the hot air through the mesh of the mesh conveyor belt structure to the bottom surface of the masterbatch to dry the bottom surface. The top surface of the masterbatch is dried by outputting heated hot air in a pulse manner on the top of the drying body. However, this drying method requires that all the masterbatches on the conveyor belt be dried before they can be output, and the drying efficiency is low. Utility Model Content

DETAILED DESCRIPTION

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] This specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it shall be protected by the patent law.

[0021] Example: Figure 1 and Figure 2 As shown, a masterbatch crystallization drying furnace comprises: a furnace body 1, a feed pipe 2 arranged at the side end of the furnace body 1, and a discharge pipe 3 and a hot air pipe 13 arranged at the bottom of the furnace body 1. A first mesh plate 4 and a second mesh plate 5 are arranged in the furnace body 1. The second mesh plate 5 is arranged obliquely above the first mesh plate 4, and the second mesh plate 5 is arranged horizontally. The first mesh plate 4 and the second mesh plate 5 are both provided with mesh holes. An active area is formed between the first mesh plate 4 and the second mesh plate 5, and the active area is connected to the feed pipe 2.

[0022] The hot air pipe 13 is arranged below the first mesh plate 4 , and the discharge pipe 3 is arranged at a lower end of the second mesh plate 5 .

[0023] The wet masterbatch particles enter the first mesh plate 4 through the feed pipe 2. During drying, the hot air in the hot air pipe 13 blows the masterbatch particles upward in the active area. At this time, they are blocked by the second mesh plate 5 and stay in the active area and jump in the active area. The water evaporates during the drying process of the masterbatch particles, causing the volume of the masterbatch particles to decrease. At this time, the dry masterbatch particles pass through the mesh of the second mesh plate 5 under the blowing action of the hot air flow and enter the second mesh plate 5. The second mesh plate 5 slides down and is discharged into the discharge pipe 3.

[0024] A scraper 6 is provided on the upper plate surface of the first mesh plate 4, and the scraper 6 reciprocates above the first mesh plate 4 through a reciprocating drive mechanism 7. There are two scrapers 6, which are connected in an L shape, and the two scrapers 6 are respectively inclined to the upper plate surface of the first mesh plate 4.

[0025] The reciprocating drive mechanism 7 includes a sliding block 701 connected to both ends of the scraper 6, a screw rod 702 threadedly connected to the sliding block 701, and a driving motor 705 for driving the screw rod 702 to rotate. A sliding groove 11 for installing the sliding block 701 is provided on the inner wall of the furnace body 1.

[0026] The reciprocating drive mechanism 7 further includes a transmission rod 703 , which is disposed at the end of a screw rod 702 . The two screw rods 702 are respectively connected to the transmission rod 703 via a bevel gear set 704 . A drive motor 705 is connected to the end of the transmission rod 703 .

[0027] When the driving motor 705 drives the transmission rod 703 to rotate, the two sets of bevel gear sets 704 drive the two screw rods 702 to rotate synchronously, so that the two sliding blocks 701 drive the scraper 6 to move, thereby scraping off the masterbatch attached to the first mesh plate 4.

[0028] like Figure 3 As shown, a limiting groove 706 is provided on the side end surface of the sliding block 701 , and the end of the scraper blade 6 is located in the limiting groove 706 and the end of the scraper blade 6 is installed in the limiting groove 706 through the rotating shaft 601 .

[0029] A return spring 707 is arranged in the limit groove 706, one end of the return spring 707 is connected to the scraper 6, and the other end is connected to the inner wall of the limit groove 706. In this way, when the scraper 6 encounters resistance during movement, it can swing up and down slightly to avoid damage to the scraper 6; when the resistance disappears, the scraper 6 returns to rest against the surface of the first mesh plate 4 again.

[0030] A support plate 8 is provided at the end of the first mesh plate 4, a damping spring 9 is connected to the upper end of the second mesh plate 5 and the support plate 8, and a vibration motor 10 is connected to one end of the second mesh plate 5. A vertical baffle 12 is provided on the lower plate surface of the second mesh plate 5, and the baffle 12 is located inside the support plate 8 to prevent the masterbatch from escaping from the gap between the upper end of the support plate 8 and the second mesh plate 5.
