Description

Technical Field

[0001] The utility model relates to the technical field of granulating equipment, in particular to a discharging structure at the tail of a cooling water tank for masterbatch processing. Background Art

[0002] Plastic masterbatch is a very important raw material in the plastic processing industry. It is a uniform particle made of an excessive amount of additives and carrier resin through a special processing method. This kind of particle plays a key role in the production process of plastic products;

[0003] The preparation of masterbatch usually requires the following equipment: mixer: used to uniformly mix resin and various additives; melt extruder: used to melt and mix raw materials and form masterbatch; pelletizer: cutting the melted and extruded material into particles of a specified length; screening machine: ensuring the consistency of masterbatch size and removing impurities; cooling system: used to cool the hot material just cut into pellets; packaging equipment: packaging the cooled masterbatch.

[0004] The cooling system generally uses a long water tank for cooling. The extruded plastic strip enters the water tank, and then as it is conveyed backward, the soft plastic strip is gradually cooled into a hard and brittle plastic strip. Refer to Figure 1 , when the plastic strip is just extruded, it is relatively soft, so the arc when it transitions into the water tank is relatively large. After cooling, the plastic strip becomes hard and brittle. In order to avoid breaking the plastic strip, it can only transition to the outside of the water tank through a relatively small arc and a long distance, and after transitioning to the outside of the water tank, it also needs to be bent downward to a horizontal state for the subsequent traction device to pull it to the pelletizing equipment. Since the hard and brittle plastic strip at the tail end gradually detaches from the water surface, the actual cooling distance is shortened, affecting the cooling effect. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defect that the hard and brittle plastic strip at the tail end in the prior art gradually detaches from the water surface, requiring a long span, and the actual cooling distance is shortened, affecting the cooling effect, and to propose a discharging structure at the tail of a cooling water tank for masterbatch processing.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A discharging structure at the tail of a cooling water tank for masterbatch processing, used for a cooling water tank. The cooling water tank is sequentially provided with independent first water tank and second water tank along the direction of plastic strip traction. First through hole and second through hole on the same horizontal line are respectively arranged on opposite sides of the second water tank. The first through hole communicates the first water tank and the second water tank, and the second through hole communicates with the outside. The height of the first liquid level in the first water tank is always higher than the height of the first through hole, and the height of the second liquid level in the second water tank is always lower than the height of the first through hole. The plastic strip sequentially passes through the first through hole and the second through hole.

[0008] An outlet hole is provided at the bottom of the second water tank, and an inlet hole is provided at the bottom of the first water tank. A water pump is installed in communication between the outlet hole and the inlet hole.

[0009] The inlet hole is arranged close to the extruder.

[0010] The cooling water tank includes a bottom panel, a front enclosure panel, a rear enclosure panel, a left enclosure panel, and a right enclosure panel. The right enclosure panel is arranged close to the extruder. The left enclosure panel is provided with the second through hole. A partition board is fixedly connected inside the cooling water tank. The side of the partition board close to the extruder is the first water tank, and the side of the partition board far from the extruder is the second water tank. The partition board is provided with the first through hole.

[0011] The diameters of the first through hole and the second through hole are both larger than the diameter of the plastic strip.

[0012] A tail discharging structure of a cooling water tank for masterbatch processing proposed by the present utility model has the beneficial effects that: this device is provided with two water storage tanks. The first water tank is the main water tank, which is used to cool the plastic strip extruded by the extruder. The second water tank is used to receive the liquid leaking out from the first through hole. And the height of the first through hole is between the first liquid level and the second liquid level, ensuring that the liquid will not flow out of the cooling water tank. Through the cooling water tank with this kind of structure, it can ensure that the plastic strip hardened after cooling is discharged straight, not only shortening the discharging distance, but also avoiding the plastic strip from being broken.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0017] Refer to Figure 2, A discharging structure at the tail of the cooling water tank for masterbatch processing, which is used for the cooling water tank 1. The cooling water tank 1 is sequentially provided with an independent first water tank 2 and a second water tank 4 along the traction direction of the plastic strip. First through holes 5 and second through holes 6 on the same horizontal line are respectively arranged on the opposite sides of the second water tank 4. The first through hole 5 communicates with the first water tank 2 and the second water tank 4, and the second through hole 6 communicates with the outside. The height of the first liquid level 3 in the first water tank 2 is always higher than the height of the first through hole 5, and the height of the second liquid level 7 in the second water tank 4 is always lower than the height of the first through hole 5. The plastic strip sequentially passes through the first through hole 5 and the second through hole 6.

[0018] Reference Figure 2 , Two water storage tanks are provided in this device. The first water tank 2 is the main water tank, which is used to cool the plastic strip extruded by the extruder. The second water tank 4 is used to receive the liquid leaking from the first through hole 5. And the height of the first through hole 5 is located between the first liquid level 3 and the second liquid level 7, ensuring that the liquid will not flow out of the cooling water tank 1. Through the cooling water tank with this structure, it can ensure that the plastic strip hardened after cooling is discharged straight, not only shortening the discharging distance, but also avoiding the plastic strip from being broken.

[0019] A water outlet hole 8 is arranged at the bottom of the second water tank 4, and a water inlet hole 10 is arranged at the bottom of the first water tank 2. A water pump 9 is connected and installed between the water outlet hole 8 and the water inlet hole 10. The leaked liquid in the second water tank 4 is pumped into the first water tank 2 by the water pump 9 to ensure that the height of the first through hole 5 is located between the first liquid level 3 and the second liquid level 7.

[0020] As an implementation method, the water inlet hole 10 is arranged close to the extruder. The liquid temperature close to the extruder is much higher than the liquid temperature at the tail end of the cooling water tank 1. Therefore, this kind of setting can better balance the water temperature in the cooling water tank 1.

[0021] The cooling water tank 1 includes a bottom panel, a front enclosure, a rear enclosure, a left enclosure, and a right enclosure. The right enclosure is arranged close to the extruder, and the left enclosure is provided with the second through hole 6. A partition 11 is fixedly connected in the cooling water tank 1. The side of the partition 11 close to the extruder is the first water tank 2, and the side of the partition 11 far from the extruder is the second water tank 4. The partition 11 is provided with the first through hole 5, which is convenient for improving the existing cooling water tank. Only a partition needs to be installed and corresponding through holes need to be drilled.

[0022] The diameters of the first through hole 5 and the second through hole 6 are both larger than the diameter of the plastic strip, which is convenient for the smooth discharge of the plastic strip.

[0023] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, the technical solutions, concepts, and designs obtained by equivalent replacement or change should all be covered within the protection scope of the present utility model.
