Description

Technical Field

[0001] This utility model relates to the field of granulation equipment, specifically a high-efficiency slag removal device for underwater granulation equipment. Background Technology

[0002] Thermoplastic polyurethane elastomer (TPU) is a linear block copolymer composed of oligomeric polyol soft segments and diisocyanate-chain extender hard segments. By recycling TPU waste, it can be reused after granulation. TPU granulation is usually carried out using an underwater granulator. After granulation, the material is stretched and cooled in water before being cut. After stretching, the material enters the water and is cooled. Impurities in the water or insufficient filtration of the circulating water may adhere to the surface of the stretched material, forming slag. Therefore, it is necessary to remove slag from the water tank to avoid excessive slag formation.

[0003] However, since the strips need to be continuously cooled during the granulation process, cleaning the cold water tank is quite troublesome. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-efficiency slag removal device for underwater granulation equipment, solving the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a high-efficiency slag removal device for underwater granulation equipment, comprising a cold water tank, the cold water tank comprising: a first water chamber and a second water chamber, a partition slot is provided inside the cold water tank between the first water chamber and the second water chamber, a drain valve pipe is provided on the lower surface of the first water chamber, a water-blocking insert is provided inside the partition slot, a guide slider is installed on the upper surface of the cold water tank, a sliding sleeve is provided on the outer side of the guide slider, a limiting groove is provided on the lower surface of the sliding sleeve corresponding to the outer side of the guide slider, a connecting frame is installed on one side of the sliding sleeve inside the cold water tank, and a guide roller is arrayed on the upper surface of the connecting frame.

[0006] As a further improvement of this utility model: the sliding sleeve is connected to a support frame at the end away from the connecting frame.

[0007] As a further improvement of this utility model: a water spray bracket is installed on one side above the second water tank, and a water spray pipe is installed inside the water spray bracket.

[0008] As a further embodiment of this utility model: the water-proof insert is engaged with the partition slot, and the sliding sleeve is slidably connected to the guide slider through the limiting groove.

[0009] As a further improvement of this utility model: the water spray pipe is externally connected to a water injection mechanism, and the water spray bracket is fixedly connected to the cold water tank.

[0010] As a further improvement of this utility model: an inclined guide plate is provided on the lower surface of the first water tank, and the drain valve pipe is connected to the first water tank.

[0011] As a further improvement of this utility model, the support frame is fixedly connected to the sliding sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The cold water tank can be moved in a controlled manner by the support frame and sliding sleeve.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-5 As shown, this embodiment provides a high-efficiency slag removal device for an underwater granulation equipment, including a cold water tank 1. The cold water tank 1 includes a first water chamber 103 and a second water chamber 104. A partition slot 102 is provided inside the cold water tank 1 between the first water chamber 103 and the second water chamber 104. A drain valve pipe 105 is provided on the lower surface of the first water chamber 103. An inclined guide plate is provided on the lower surface of the first water chamber 103. The drain valve pipe 105 is connected to the first water chamber 103. A water-proof insert is provided inside the partition slot 102. Plate 106, water-proof insert plate 106 is snapped into partition slot 102, guide slider 101 is installed on the upper surface of cold water tank 1, sliding sleeve 3 is provided on the outer side of guide slider 101, and a limiting groove 301 is opened on the lower surface of sliding sleeve 3 corresponding to the outer side of guide slider 101. Sliding sleeve 3 is limited and slidably connected to guide slider 101 through limiting groove 301. A connecting frame 302 is installed on one side of sliding sleeve 3 inside cold water tank 1, and guide rollers 303 are arrayed on the upper surface of connecting frame 302.

[0022] like Figure 2-3 As shown, in this embodiment, the sliding sleeve 3 is connected to a support frame 2 at the end away from the connecting frame 302. The support frame 2 is fixedly connected to the sliding sleeve 3. A water spray bracket 5 is installed on one side above the second water tank 104. A water spray pipe 4 is installed inside the water spray bracket 5. A water injection mechanism is connected to the outside of the water spray pipe 4. The water spray bracket 5 is fixedly connected to the cold water tank 1.

[0023] The working principle of this utility model is as follows: After the extruded strip material being granulated is pulled out, the entire strip is aligned with the inside of the guide roller 303, and the entire connecting frame 302 is aligned with the inside of the first water tank 103. Cooling water is injected into the entire interior of the cold water tank 1. When a lot of impurities accumulate in the water inside the cold water tank 1 during use, a thrust is applied from the end of the cold water tank 1 with the second water tank 104, and water is continuously injected into the second water tank 104 through the water spray pipe 4. This controls the sliding sleeve 3 to move in a limited position on the guide slider 101 at the upper end of the cold water tank 1 using the limiting groove 301, thereby positioning the connecting frame 302 and the guide roller 103. After the roller 303 moves to the position of the corresponding second water tank 104, the water-blocking plate 106 is inserted into the partition slot 102 to separate the first water tank 103 and the second water tank 104. After the water in the first water tank 103 is completely drained by opening the drain valve pipe 105, the first water tank 103 is cleaned and rinsed with clean water. Then the water-blocking plate 106 is removed, and water is continuously injected into the cold water tank 1 through the spray pipe 4. Then the connecting frame 302 is controlled to move into the first water tank 103 again. Therefore, the cleaning of the cold water tank 1 can be completed without stopping granulation.
