Embodiment 1

[0027] Embodiment 1 is basically as follows:

[0028] An accelerated cooling system for plastic pellets, such as figure 1 shown and figure 2 As shown, it includes a bracket 11 and a cooling groove 10 arranged on the bracket 11. The cooling groove 10 is shaped like a rubber plate. The cooling tank 10 includes a rapid cooling section 101 and a sinking and floating section 102 , except for the rapid cooling section 101 , other parts of the cooling tank 10 are fixed to the support 11 . The left end of the rapid cooling section 101 is where the plastic particles are fed. For circulating water in the cooling tank 10, a circulation pump 5 is set at the left part of the cooling tank 10, figure 1 The direction of the middle arrow is the flow direction of cooling water.

[0029] The bottom of the quick-cooling section 101 is provided with a jacking mechanism, and the jacking mechanism includes a plurality of cylinders fixed with the bracket 11 by bolts. The cylinders of this embodi...

Embodiment 2

[0035] The difference from Embodiment 1 is that the bubble tube 30 is connected with a dry ice vaporization chamber, so that the gas supplied by the gas supply device is mixed with carbon dioxide gas with a lower temperature formed by the gasification of dry ice, which can accelerate the cooling of water and plastic particles. cooling process.

Abstract

The present invention relates to the technical field of plastic granule production and processing equipment, and in particular to an accelerated cooling system for plastic granules, which includes a bracket and a cooling tank arranged on the bracket. For the cooling section and the sinking section, a jacking mechanism is provided under the quick cooling section, and the jacking mechanism is offset against the bottom of one side of the quick cooling section; there are multiple bubble tubes at the bottom of the sinking section, and a number of bubble ports are arranged on the bubble tube, and the bubble tubes are connected There is an air supply device. In this scheme, the cooling water in the rapid cooling section is used to form turbulent flow through the jacking mechanism, which is the rapid molding of plastic particles; the air bubbles are generated in the sinking and floating section through the bubble tube, which accelerates the heat dissipation inside the plastic particles and avoids the bonding of plastic particles. The problem of low cooling efficiency caused by uneven cooling water temperature in the prior art is solved, and the cooling efficiency in the production process of plastic granules is improved.

Description

technical field [0001] The invention relates to the technical field of equipment for production and processing of plastic particles, in particular to an accelerated cooling system for plastic particles. Background technique [0002] During the production and processing of plastic pellets, it is necessary to extrude the plastic into strips from the mesh of the extrusion die after melting the plastic, and then cut the extruded strips of plastic into pellets. In order to make the plastic particles form quickly and avoid the bonding between the plastic particles, it is necessary to cool the cut plastic particles. At present, cooling water is generally used for cooling in the cooling tank. [0003] However, the existing cooling tank has the following problems: 1. The temperature distribution of the cooling water in the cooling tank is uneven. The water around the plastic particles absorbs heat and the temperature rises, which hinders the continuous heat exchange of the plastic pa...
