Description

Technical Field

[0001] The utility model relates to the field of plastic particle processing, in particular to a plastic particle heat exchange tank. Background Art

[0002] Plastic pellets are a very important raw material in modern industry. In the process of plastic pellet processing and production, the plastic pellet raw materials need to be mixed, melted and extruded into plastic pellet lines, and then the plastic pellet lines are cooled to make them easy to cut hardness, and finally cut into plastic pellets. Traditional plastic pellet line cooling usually adopts air cooling and water cooling. Water cooling requires the plastic pellet lines to pass through the cooling water tank for cooling. Due to the differences in different plastic materials, performance and extrusion size of the extruder, single water tank cooling has the defect of different cooling degrees. In addition, when the molten plastic is continuously cooled through the water tank, the water temperature will rise, which is prone to insufficient cooling. Insufficient cooling will lead to poor pelletizing effect and easy sticking of the knife. Summary of the invention

[0003] 1. Technical issues to be solved

[0004] The technical problem to be solved by the utility model is that after the plastic particle lines are formed, water cooling and shaping are required, and the water temperature in the cooling water tank will rise over time, making it easy for the subsequent plastic particle lines to be insufficiently cooled, resulting in poor pelletizing effect and easy sticking to the knife.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0027] See also Figure 1-5 A plastic particle heat exchange tank shown in the figure comprises a cooling water tank 1, cooling water tank support plates 2 are arranged on both sides of the cooling water tank 1, a first leg 3 is arranged below the cooling water tank support plate 2, the cooling water tank support plate 2 and the first leg 3 are used to support the cooling water tank 1, a heat dissipation water tank 4 is arranged between the first leg 3, the heat dissipation water tank 4 is located below the cooling water tank 1, a water pumping hole 5 is opened on one side of the heat dissipation water tank 4, a water pumping pipe 6 is externally connected to the water pumping hole 5, one end of the water pumping pipe 6 is connected to a water pump 7, a drainage pipe 8 is arranged above the water pump 7, a water storage tank 9 is arranged above the cooling water tank 1, the water entering the heat dissipation water tank 4 is transported to the water storage tank 9 through the water pump 7, and a second leg 10 is arranged around the lower surface of the water storage tank 9.

[0028] The cooling water tank 1 is a rectangular water tank, and a liquid level sensor 11 is provided on one inner wall of one side, and a water injection hole 12 is provided on one side of the liquid level sensor 11. A plurality of first drainage holes 13 are provided on the bottom surface of the cooling water tank 1. The liquid level sensor 11 is used to monitor the liquid level of the cooling water in the cooling water tank 1. When the cooling water consumption exceeds the rated value, the cooling water is replenished to the cooling water tank 1 in time through the water injection hole 12. The first drainage hole 13 is an arc-shaped surface close to the liquid level sensor 11. When the plastic particle line passes through the cooling water tank 1 for cooling, the first drainage hole 13 with a rounded surface is smoother, so that the plastic particle line will not be scratched with the hollow hole. The heat dissipation water tank 4 is fixed between the first legs 3 by welding. A heat dissipation fin 41 is provided at the bottom of the heat dissipation water tank 4. The outer wall of the heat dissipation water tank 4 is thinner than the cooling water tank 1 and the water storage tank 9, and is made of high heat dissipation metal material, so that the heat dissipation of the water tank 4 is not too large. The water containing heat entering the heat dissipation water tank 4 can dissipate its heat better. The heat dissipation fins 41 at the bottom are also made of high heat dissipation metal material to further dissipate heat. The cooling water after heat dissipation enters the water storage tank 9 through the water pump 7. A second drainage hole 91 is opened on the bottom of the water storage tank 9. The size and number of the second drainage holes 91 are the same as the first drainage holes 13, so that the amount of water transported from the water storage tank 9 to the cooling water tank 1 and the amount of water transported from the cooling water tank 1 to the heat dissipation water tank 4 are basically the same to achieve balance. A water inlet 92 is opened on one side of the water storage tank 9, and the water inlet 92 is connected to the drainage pipe 8. The water pumped out by the water pump 7 enters the water storage tank 9 from the drainage pipe 8 through the water inlet 92, and leaks into the cooling water tank 1 through the second drainage hole 91. A feed port 14 is provided at one end of the cooling water tank 1, and a discharge port 15 is provided at the other end. The feed port 14 and the discharge port 15 are both notch-shaped arcs, and their sizes are the same.

[0029] The specific working principle is as follows: the extrusion and pulling process squeezes the plastic particles into strips of plastic particle lines, which enter the cooling water tank 1. The cooling water tank 1 is provided with cooling water to cool the plastic particle lines to change their hardness. The high temperature of the plastic particle lines will be transferred to the water in the cooling water tank 1, and the water in the cooling water tank 1 will slowly leak into the heat dissipation water tank 4 through the first drainage hole 13. When entering the heat dissipation water tank 4, the water will contact with the air during the falling process to dissipate part of the heat and enter the heat dissipation water tank 4. Heat is dissipated, and the heat-dissipated water will enter the water pumping pipe 6 through the water pumping port 5, be pumped out by the water pump 7 into the drainage pipe 8, and then enter the knife water storage tank 9 through the water inlet 92, and then leak into the cooling water tank 1 through the second drainage hole 91 to complete the water cooling cycle. A feed port 1 is provided at one end of the cooling water tank 1, and a discharge port 12 is provided at the other end. Both the feed port 11 and the discharge port 12 are notched arcs with the same size, which are convenient for the formed plastic particle lines with heat to pass through. The notch is an arc shape to reduce its friction and make it more lubricated and convenient to pass through.
