Description

Technical Field

[0001] This utility model relates to the technical field of water tank equipment for underwater pelletizers, specifically a water tank structure for an underwater pelletizer. Background Technology

[0002] Currently, plastic product processing in my country largely involves plasticizing plastic powder and then molding it. Extruders are the most widely used equipment in polymer processing. After the polymer is mixed with various additives, it is fed into the extruder to melt and further mix evenly. It is then passed through a multi-hole die to form multiple strips, which are then cut into pellets. There are hot-cut pellets and cold-cut pellets. Hot-cut pellets are made by cooling the strips with air or water while cutting them with blades after they leave the die. Underwater pelletizers are a type of hot-cut plastic pellet equipment commonly used in the plastic pelletizing industry.

[0003] An investigation revealed that a Chinese utility model patent discloses a water tank structure for an underwater pelletizer (publication number: CN214644992U), which includes a water tank body, a door at the upper end of the water tank body, a water inlet tank that is connected through the upper end of the water tank body, and a water inlet on the side wall of the water inlet tank. The water tank body has a double-layer inner wall structure. Multiple layers of first filter screens are installed on a section of the water tank body directly below the water inlet.

[0004] In the aforementioned patent, by setting up multiple layers of first filter screens, impurities in the water can be filtered layer by layer, thereby improving the filtration effect. However, during use, the impact of water flow on the filter screens may cause them to shift, which may affect the filtration path of impurities. Consequently, some impurities may not be effectively intercepted, which may reduce the overall filtration efficiency.

[0005] Therefore, this utility model provides a water tank structure for an underwater pelletizer to solve the above problems. Utility Model Content

[0026] 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.

[0027] This utility model provides a water tank structure for an underwater pelletizer, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the underwater pelletizer water tank structure includes a support frame 1, a water tank body 2 fixedly installed on the support frame 1, a tank door 3 rotatably installed on the water tank body 2, a water inlet tank 4 fixedly installed on the water tank body 2, a water inlet pipe 5 fixedly installed on the water inlet tank 4, a water outlet pipe 6 fixedly installed on the water tank body 2, a filter plate 9 disposed inside the water tank body 2, and a fixing mechanism disposed inside the water tank body 2 for controlling the filter plate 9.

[0028] The fixing mechanism includes a limiting frame 7 fixedly installed on the inner walls of both sides of the water tank body 2, a mounting frame 8 fixedly installed inside the water tank body 2, a first spring 10 set inside the mounting frame 8, a baffle 11 slidably installed inside the mounting frame 8, a telescopic rod 12 fixedly installed inside the limiting frame 7, a pressing plate 13 fixedly installed on the movable end of the telescopic rod 12, a second spring 14 sleeved on the side surface of the telescopic rod 12, and an insertion rod 15 fixedly installed on the pressing plate 13. The filter plate 9 is slidably connected inside the mounting frame 8, and the mounting frame 8 has a slot for the insertion rod 15.

[0029] One end of the first spring 10 is fixedly connected to one side of the mounting frame 8, and the other end of the first spring 10 is fixedly connected to one side of the baffle 11. One end of the second spring 14 is fixedly connected to the bottom inner wall of the limiting frame 7, and the other end of the second spring 14 is fixedly connected to the bottom of the pressing plate 13. The insertion rod 15 passes through the limiting frame 7 and the mounting frame 8 in sequence.

[0030] When using the underwater pelletizer's water tank structure, first place the support frame 1 in a suitable position, then insert the filter plate 9 into the water tank body 2. The filter plate 9 is limited by the insertion rod 15. Then, mixed water enters the water inlet tank 4 through the inlet pipe 5. The water inlet tank 4 can block the mixed water and allow it to move downwards evenly, preventing impurities from accumulating and reducing splashing. The water enters the water tank body 2 through the inlet tank 4 and is filtered by the filter plate 9. The filtered water is discharged by opening the valve on the outlet pipe 6. When the filter plate 9 needs to be replaced, manually press down on the pressing plate 13. The movement of the pressing plate 13 moves the insertion rod 15 downwards synchronously, simultaneously compressing the second spring 14 and retracting the telescopic rod 12 until the insertion rod 15 is removed from the filter plate 9. After the filter plate 9 is moved out of the slot, the elastic potential energy of the first spring 10 pushes the baffle 11, which in turn pushes the filter plate 9 outward a certain distance. The insertion rod 15 is no longer on the same vertical line as the slot, so it can no longer limit the filter plate 9. Then, the filter plate 9 is pulled out by manually pulling the handle on one side of the filter plate 9. After that, the pressing plate 13 is pressed down to insert the new filter plate 9 into the water tank body 2. It first contacts the baffle 11. Continuing to insert it will squeeze the first spring 10 until the slot moves to the same vertical line as the insertion rod 15. The elastic potential energy of the second spring 14 drives the pressing plate 13 to move upward. The movement of the pressing plate 13 drives the insertion rod 15 to move synchronously until the insertion rod 15 is inserted into the slot, thus limiting the filter plate 9 and preventing the filter plate 9 from shifting during use.

[0031] Furthermore, in order to block the water inlet pipe 5 when not in use, such as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a fixing block 16 is fixedly connected to one side of the water inlet tank 4, and a hoop 17 is rotatably connected inside the fixing block 16. One of the hoop 17 has a first threaded rod 18 rotatably inside it.

[0032] The first threaded rod 18 is screwed to the side surface of the first rotating block 19, and the inside of the hoop 17 is movably connected to the cover 20, which is adapted to the water inlet pipe 5.

[0033] When the underwater pelletizer water tank structure is in use, when not in use, the cover 20 is aligned with the water outlet pipe 6, and then the two hoop rings 17 are rotated to wrap around the cover 20. Then, the first rotating block 19 is put on the first threaded rod 18 and rotated until the top of the first rotating block 19 contacts the bottom hoop ring 17, thereby completing the fixation of the cover 20.

[0034] It should be noted that, in order to close door 3, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, a hinge block 21 is fixedly connected to one side of the water tank body 2, and a second threaded rod 22 is rotatably connected inside the hinge block 21.

[0035] The second threaded rod 22 has a second rotating block 23 screwed onto its side surface, and the bottom of the second rotating block 23 is in contact with the top of the door 3.

[0036] When the tank structure of this underwater pelletizer needs to be closed, the second threaded rod 22 is rotated upward to abut against the tank door 3. Then, the second rotating block 23 is fitted onto the second threaded rod 22. The second rotating block 23 is rotated until the bottom of the second rotating block 23 contacts the top of the tank door 3, thereby fixing the tank door 3.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
