Description

Technical Field

[0001] This utility model relates to the field of extrusion equipment technology, specifically to a phase change material extrusion device. Background Technology

[0002] Phase change materials (PCMs) are substances that change their physical state and provide latent heat while maintaining a constant temperature. The process of changing physical properties is called a phase change process. During this process, PCMs absorb or release a large amount of latent heat. Once widely used in human life, these materials will become the best green and environmentally friendly carriers for energy conservation and protection. In my country, they have already been included in the national research and development and utilization sequence.

[0003] Chinese utility model patent CN218857643U discloses a phase change material extrusion device, including an extruder body and a feeding mechanism connected to the feed end of the extruder body. The feeding mechanism assists in accelerating the delivery of the phase change material into the extruder body. At least one vibrator is fixed to the outer wall of the feeding hopper, and at least three elastic elements are equally spaced around the circumference of the feeding hopper side wall. The feeding hopper is connected to the feed end of the extruder body via the at least three elastic elements, and the discharge end at the bottom of the feeding hopper extends into the feed end of the extruder body. The elastic elements are used to convert the driving force of the vibrator into the vibration force of the feeding hopper. A stirring element is fixed to the top of the feeding hopper and is used to stir the phase change material in the feeding hopper. This solves the problem that material easily accumulates at the feed end, affecting normal feeding and resulting in slow feeding speed.

[0004] To clean the phase change material adhering to the inner wall of the hopper, the aforementioned extrusion device is equipped with a stirring motor, a rotating shaft, a stirring rod, and scrapers on the hopper. However, the scrapers and stirring rods in the extrusion device are fixedly connected, meaning the device lacks the function of disassembling the scrapers. After prolonged use, the scrapers will wear down. If the worn scrapers are not replaced in time, the scraping effect will be affected. Utility Model Content

The wing bolt 304 is connected to the support plate 301 by a threaded connection. A threaded hole adapted to the wing bolt 304 is provided on one side of the support plate 301.

[0024] A stirring motor 4 is installed on the top of the U-shaped bracket 302. The output shaft of the stirring motor 4 is fixedly connected to a rotating shaft 401. Stirring rods 402 are fixedly installed on both sides of the rotating shaft 401. A connecting seat 5 is fixedly installed at one end of the stirring rod 402. A connecting groove is opened on one side of the connecting seat 5, and a connecting block 501 is movably installed inside the connecting groove. A scraper 502 is fixedly installed at one end of the connecting block 501. An insertion hole is opened inside the connecting block 501, and a fixing bolt 503 is movably installed inside the insertion hole. The connection between the fixing bolt 503 and the connecting seat 5 is a threaded connection. A threaded hole that matches the fixing bolt 503 is opened on the top of the connecting seat 5.

[0025] Specifically, a rotating blade 403 is fixedly disposed on the surface of the rotating shaft 401.

[0026] In this embodiment, by setting a rotating blade 403, the rotating blade 403 can push the phase change material in the feed hopper 3 into the extruder body 1, thereby increasing the feeding speed.

[0027] Specifically, the connection between the wing bolt 304 and the mounting block 303 is a movable plug-in connection.

[0028] In this embodiment, by setting a wing bolt 304, the wing bolt 304 is rotated and moved by turning the wing bolt 304. When one end of the wing bolt 304 is inserted into the socket on the mounting block 303, the U-shaped bracket 302 can be restricted.

[0029] Specifically, the connection between the fixing bolt 503 and the connecting block 501 is a movable plug-in connection.

[0030] In this embodiment, a fixing bolt 503 is set, and the fixing bolt 503 is rotated and moved by turning the fixing bolt 503. When one end of the fixing bolt 503 is inserted into the socket on the connecting block 501, the scraper 502 can be restricted.

[0031] Specifically, the scraper 502 is in contact with the inner wall of the hopper 3.

[0032] In this embodiment, by setting up a scraper 502, the rotating scraper 502 can scrape off the phase change material adhering to the inner wall of the hopper 3.

[0033] Specifically, there are four stirring rods 402, and the four stirring rods 402 are divided into two groups, with the two groups of stirring rods 402 being symmetrically distributed.

The rotating stirring rod 402 can stir the phase change material, and the rotating scraper 502 can scrape off the phase change material adhering to the inner wall of the hopper 3.

[0036] When disassembling the U-shaped bracket 302, the wing bolt 304 is rotated and moved by turning it. When one end of the wing bolt 304 is removed from the socket on the mounting block 303, the restriction on the U-shaped bracket 302 can be released. Then the U-shaped bracket 302, the stirring rod 402 and the scraper 502 can be removed from the hopper 3 together.

[0037] When disassembling scraper 502, the fixing bolt 503 is rotated and moved by turning the fixing bolt 503. When one end of the fixing bolt 503 is moved out of the socket on the connecting block 501, the restriction on scraper 502 can be released, and scraper 502 can then be removed.

[0038] When installing scraper 502, insert the connecting block 501 on scraper 502 into the connecting groove on connecting seat 5, and then rotate and move the fixing bolt 503 by turning it.

[0039] When installing the U-shaped bracket 302, insert the mounting block 303 on the U-shaped bracket 302 into the mounting groove on the support plate 301, and then rotate the wing bolt 304 by turning it. When one end of the wing bolt 304 is inserted into the socket on the mounting block 303, the U-shaped bracket 302 can be restricted, thereby realizing the installation of the U-shaped bracket 302.

[0040] In summary, this phase change material extrusion device, by setting up a wing bolt 304, allows the wing bolt 304 to rotate and move by turning it. When one end of the wing bolt 304 is removed from the insertion hole on the mounting block 303, the restriction on the U-shaped bracket 302 can be released. Then, the U-shaped bracket 302, stirring rod 402, and scraper 502 can be removed from the hopper 3 together, thus facilitating the maintenance of the scraper 502. By setting up a fixing bolt 503, the fixing bolt 503 can rotate and move by turning it. When one end of the fixing bolt 503 is removed from the insertion hole on the connecting block 501, the restriction on the scraper 502 can be released, and the scraper 502 can be disassembled. This achieves the function of detachable scraper 502, thus facilitating the replacement of scraper 502.
