DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0020] Reference Figure 1-Figure 2 A dust removal device for masterbatch pelletizing comprises a feed pipe 13 which is connected and installed below a pelletizer discharge port 1 and is vertically arranged. The feed pipe 13 has at least a first mesh surface 11 and a second mesh surface 14. The first mesh surface 11 is connected and installed with a first dust collecting mechanism, and the second mesh surface 14 is connected and installed with a second dust collecting mechanism. The apertures of the first mesh surface 11 and the second mesh surface 14 are smaller than the size of the masterbatch and larger than the size of the debris. The first dust collecting mechanism and the second dust collecting mechanism are connected to a dust collector through an airflow switching component.
[0021] When the device is in use, the pelletizer discharge port 1 discharges the freshly cut masterbatch and debris (defined as a mixture), and the mixture falls in the discharge pipe 13. At the same time, negative pressure suction is generated by the vacuum cleaner, and the first vacuum mechanism or the second vacuum mechanism is switched to be connected to the vacuum cleaner through the airflow switching component. When the first vacuum mechanism is connected to the vacuum cleaner, the airflow carries the debris through the first mesh surface 11 into the vacuum cleaner. When the second vacuum mechanism is connected to the vacuum cleaner, the airflow carries the debris through the second mesh surface 14 into the vacuum cleaner. The first mesh surface 11 and the second mesh surface 14 are switched to work alternately to remove the debris and reduce the probability of blockage.
[0022] Furthermore, in order to improve the dust removal effect, a plurality of staggered baffles 12 are installed inside the feeding pipe 13. When the mixture falls, it hits the baffles 12, so that the debris and the mother particles are better separated by the impact.
[0023] As an embodiment, the first dust suction mechanism includes a first cover 10, the first cover 10 covers the first mesh surface 11, the first cover 10 has a first extension pipe 7, and the first extension pipe 7 is connected to the vacuum cleaner through an airflow switching component; the second dust suction mechanism includes a second cover 15, the second cover 15 covers the second mesh surface 14, the second cover 15 has a second extension pipe 18, and the second extension pipe 18 is connected to the vacuum cleaner through an airflow switching component.
[0024] The first cover 10 covers the first mesh surface 11. When the first extension pipe 7 generates negative pressure, the airflow passes through the first mesh surface 11 from the feed pipe 13 and converges to the first cover 10. The working principle of the second cover 15 is the same.
[0025] An embodiment of an airflow switching assembly includes a first connecting pipe 6, a second connecting pipe 20, and a first sleeve 2. The first sleeve 2 is connected to a vacuum cleaner through a switching mechanism, wherein the switching mechanism may be an electric valve or other mechanical valve in the prior art. The first sleeve 2 has a second port 5 and a fourth port 22. The switching mechanism enables the second port 5 or the fourth port 22 to be connected to the vacuum cleaner. One end of the first connecting pipe 6 is connected to the second port 5 and the other end is connected to the first extension pipe 7. One end of the second connecting pipe 20 is connected to the second extension pipe 18 and the other end is connected to the fourth port 22.
[0026] Furthermore, the first connecting tube 6 has a first mounting tube 9, which is sleeved on the first extension tube 7, the first extension tube 7 has a first air inlet hole 8, and the first mounting tube 9 can open or close the first air inlet hole 8; the second connecting tube 20 has a second mounting tube 19, which is sleeved on the second extension tube 18, the second extension tube 18 has a second air inlet hole 17, and the second mounting tube 19 can open or close the second air inlet hole 17.
[0027] When working, refer to Figure 1 When the first dust collecting mechanism is required to work, the first installation tube 9 closes the first air inlet hole 8, and the second air inlet hole 17 is opened at the same time. The vacuum cleaner generates negative pressure in the first connecting tube 6, and part of the airflow passes through the second air inlet hole 17 through the second mesh surface 14 and enters the discharge pipe 13. Then, the airflow at the bottom of the discharge pipe 13 and the airflow entering from the second air inlet hole 17 carry debris through the first mesh surface 11, converge to the first cover 10 and be sucked into the vacuum cleaner, thereby playing a role in clearing the second mesh surface 14. Similarly, refer to Figure 2 When the second dust suction mechanism is working, the first air inlet 8 is opened and the second air inlet 17 is closed, so that the airflow flows from the first air inlet 8 to the second cover 15, thereby clearing the first mesh surface 11. In this way, it can work continuously and reduce the probability of clogging of the first mesh surface 11 and the second mesh surface 14.
[0028] As an embodiment, the switching mechanism includes a second sleeve 3 inserted into the first sleeve 2, the outer wall of the second sleeve 3 is tangent to the inner wall of the first sleeve 2, and the two are slidably connected, the second sleeve 3 has a first port 4, a third port 21, and a fifth port 23, the second sleeve 3 is slid, the second port 5 is connected to the first port 4, and the second sleeve 3 closes the fourth port 22, or the second sleeve 3 is slid, the second sleeve 3 closes the second port 5, and the third port 21 is connected to the fourth port 22, and the fifth port 23 is connected to the dust collection end of the vacuum cleaner. By pushing and pulling the second sleeve 3, the switching mechanism is changed in a combined manner, such as Figure 1 As shown, the first port 4 and the second port 5 are connected to the vacuum cleaner. Figure 2 As shown, the third port 21 and the fourth port 22 are connected to the vacuum cleaner.
[0029] In order to better clear the mesh through airflow, the first mesh surface 11 and the second mesh surface 14 are arranged opposite to each other.
