Description

Technical Field

[0001] The utility model relates to the technical field of color mixing machines, in particular to a plastic particle color mixing device. Background Art

[0002] During the high-speed operation of the plastic granule color mixer, the plastic granules will cause part of the plastic to decompose due to friction and heat, releasing harmful gases. These gases may include phenol, cresol, benzene, formaldehyde, ammonia and other toxic substances, which will cause harm to human health. Therefore, it is necessary to deal with the toxic and harmful gases generated when the plastic granule color mixer is working.

[0003] After searching, it was found that the Chinese utility model patent with authorization announcement number CN215472298U discloses a plastic color mixing machine, including a tank body and an exhaust mechanism connected to the tank body. The exhaust mechanism includes a purification box, a fan, an exhaust pipe, an air supply pipe, an exhaust pipe and activated carbon. When working, the gas inside the tank body is drawn into the purification box through the exhaust pipe and the air supply pipe by the fan, and the gas is filtered by the activated carbon in the purification box. The filtered gas is discharged from the purification box through the exhaust pipe.

[0004] However, this solution has the following problems: after a period of use, the gaps in the activated carbon used as a gas purification material will gradually be occupied by impurities, and its adsorption capacity will decrease, causing the filtering effect to decay. At this time, new activated carbon needs to be replaced. In this solution, when replacing the activated carbon, the machine needs to be shut down and the purification box needs to be disassembled to take out the expired activated carbon and put in new activated carbon. This is not only troublesome to operate but also affects work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0043] like Figure 1 and Figure 2 As shown, a plastic particle color mixing device includes:

[0044] Pot body 1;

[0045] an air inlet pipe 4 connected to the pot body 1 at one end;

[0046] The box body 3 is hollow inside and is connected to the other end of the air inlet pipe 4;

[0047] An inner cylinder 6 is movably disposed in the housing 3. The inner cylinder 6 has a plurality of filter chambers for storing gas purification materials. In this embodiment, six filter chambers are provided in the inner cylinder 6. The gas purification material is preferably activated carbon. Each filter chamber has at least one air inlet end and at least one air outlet end. The air inlet end and the air outlet end form a transmission channel for delivering gas into the filter chamber. When in use, any transmission channel is connected to the air inlet pipe 4 through the movable inner cylinder 6.

[0048] The above technical solution can be used to quickly and conveniently replace the gas purification material. During use, the plastic particles inside the pot body 1 will be stirred and heated, which will cause part of the plastic to decompose and release harmful gases, thereby increasing the pressure inside the pot body 1. The harmful gases enter the box body 3 through the air inlet pipe 4, and the harmful gases enter the corresponding filter chamber in the inner tube 6. The gas purification material in the filter chamber absorbs the harmful substances, and the treated gas is discharged from the filter chamber through the exhaust end. When the gas purification material in the filter chamber fails, the air inlet end of the next filter chamber is connected to the air inlet pipe 4 through the movable inner tube 6, and the next filter chamber can be switched, and the replacement efficiency is high.

[0049] like Figure 2 As shown, in this embodiment, the box body 3 is further provided with an exhaust pipe 5 connected to the exhaust end;

[0050] The above technical solution can conveniently discharge the gas from the box body 3. After the gas passes through the filter chamber, it will be discharged from the box body 3 through the exhaust pipe 5.

[0051] like Figure 4 As shown, in this embodiment, the inner cylinder 6 is provided with a plurality of airtight partitions 7 along the axial direction, and the airtight partitions 7 divide the inner cylinder 6 into a plurality of filter chambers;

[0052] The above technical solution can be used to divide the interior of the inner cylinder 6 into multiple filter chambers, so that when the gas purification material in one filter chamber fails, it is possible to quickly switch to the next filter chamber.

[0053] like Figure 4 and Figure 5 As shown, in this embodiment, each filter chamber is provided with a sealing structure for sealing the air inlet end and the exhaust end; the sealing structure includes: a movable plate 13 that matches the shape of the filter chamber; a first sealing ring 14 provided on the side of the movable plate 13; a second sealing ring 15 provided at the end of the movable plate 13; an elastic structure for pushing the movable plate 13 to move axially along the inner cylinder 6 to fit the end of the inner wall of the box body 3; specifically, the elastic structure includes: a fixed plate 8 with a through groove, the fixed plate 8 is connected to the inner wall of the filter chamber; a sleeve 9 with one end connected to the fixed plate 8; a telescopic rod 11 with one end movably provided in the sleeve 9, and the other end of the telescopic rod 11 is connected to a fixed block 12 provided on the inner side of the movable plate 13; a first spring 10 provided in the sleeve 9 for resisting the telescopic rod 11;

[0054] The above technical solution can prevent the formation of gaps between the upper and lower ends of the inner cylinder 6 and the upper and lower ends inside the box body 3, thereby preventing gas from leaking from the gaps and affecting the filtering effect. When the inner cylinder 6 moves, the first spring 10 in the inner cylinder 6 will always push the telescopic rod 11 to move outward, so that the telescopic rod 11 drives the movable plate 13 to fit the upper and lower ends inside the box body 3. Since the end of the movable plate 13 is provided with a second sealing ring 15, the gap between the movable plate 13 and the upper and lower ends inside the box body 3 can be avoided. Similarly, the side of the movable plate 13 is also provided with a first sealing ring 14, which can prevent gas from leaking from the gap between the movable plate 13 and the inner wall of the filter chamber, thereby improving the sealing effect of the device.

[0055] like Figure 4 As shown, in this embodiment, the fixed plate 8 located at the bottom end of the filter chamber is provided with a sieve plate 26 for receiving the gas purification material in its through groove;

[0056] The above technical solution can ensure that the gas purification material can be stably placed in the filter chamber, and the sieve plate 26 can carry the gas purification material while ensuring that the gas can flow through the holes on the surface of the sieve plate 26.

[0057] like Figure 2 and Figure 3 As shown, in this embodiment, the inner cylinder 6 is rotatably disposed in the housing 3; a rotating shaft 18 is provided at the end of the inner cylinder 6, and the rotating shaft 18 is rotatably engaged with a rotating groove provided in the housing 3;

[0058] The above technical solution can facilitate the switching of the filter chamber. By rotating the rotating shaft 18, the inner cylinder 6 can be driven to rotate in the box body 3, thereby switching the filter chamber.

[0059] like Figure 3 As shown, in this embodiment, the color mixing device further includes: a prism 19 having one end disposed at the end of the rotating shaft 18; a collar 20 having a prism hole 21; a positioning pin 22 having one end connected to the collar 20, the positioning pin 22 engaging with a positioning groove 23 formed on the surface of the housing 3; a tail plate 24 connected to the other end of the prism 19; and a second spring 25 disposed between the tail plate 24 and the collar 20.

[0060] The above technical solution can facilitate the self-locking of the rotating shaft 18. When it is necessary to switch the filter chamber, the ring 20 is pulled so that the positioning pin 22 at its lower end is disengaged from the positioning groove 23 on the surface of the box body 3, thereby releasing the rotation restriction of the rotating shaft 18. When the rotating shaft 18 is rotated to the appropriate position, the ring 20 is loosened. Under the elastic action of the second spring 25, the ring 20 drives the positioning pin 22 to be inserted into the corresponding positioning groove 23 to achieve rotation limit.

[0061] like Figure 2As shown, in this embodiment, the color mixing device further includes: a box cover 17, which is threadedly connected to the top groove 16 opened at the upper end of the box body 3; a mounting plate 2 connected to the box body 3, and the mounting plate 2 is connected to the pot body 1 by bolts;

[0062] The above technical solution can facilitate the removal of the ineffective activated carbon. When the activated carbon is ineffective, the box cover 17 is opened to remove the ineffective activated carbon from the filter chamber of the inner tube 6.

[0063] Working principle: When in use, the plastic particles inside the pot body 1 will cause part of the plastic to decompose as they are stirred and heated, releasing harmful gases, which will increase the pressure inside the pot body 1. The harmful gases enter the box body 3 through the air inlet pipe 4, and the harmful gases enter the corresponding filter chamber in the inner cylinder 6. The gas purification material in the filter chamber absorbs the harmful substances, and the treated gas is discharged from the filter chamber through the exhaust end. After passing through the filter chamber, the gas will be discharged from the box body 3 through the exhaust pipe 5. When the gas purification material in the filter chamber fails, the collar 20 is pulled so that the positioning pin 22 at its lower end is disengaged from the positioning groove 23 on the surface of the box body 3, thereby releasing the rotation restriction of the rotating shaft 18. By rotating the rotating shaft 18, the inner cylinder 6 can be driven to rotate in the box body 3 until the lower When the air inlet end of a filter chamber is docked with the air inlet pipe 4, you can switch to the next filter chamber and loosen the collar 20. Under the elastic action of the second spring 25, the collar 20 drives the positioning pin 22 to insert into the corresponding positioning groove 23 to achieve rotation limit. When the inner cylinder 6 moves, the first spring 10 in the inner cylinder 6 will always push the telescopic rod 11 to move outward, so that the telescopic rod 11 drives the movable plate 13 to fit the upper and lower ends of the inside of the box body 3. Since the end of the movable plate 13 is provided with a second sealing ring 15, it is possible to avoid a gap between the movable plate 13 and the upper and lower ends of the inside of the box body 3. Similarly, the side of the movable plate 13 is also provided with a first sealing ring 14, which can prevent gas from leaking from the gap between the movable plate 13 and the inner wall of the filter chamber, thereby improving the sealing effect of the device.
