Description

Technical Field

[0001] The utility model relates to the technical field of particle production equipment, in particular to a PCR particle purification device. Background Art

[0002] PCR particles are plastic particles of post-consumer recycled materials (abbreviated as PCR). Such particles are made into brand-new plastic particles through sorting, cleaning and granulation of the recycling system after waste plastics are recycled, and are widely used in fields such as electronic appliances, automobiles, construction, and medical treatment. During the production of PCR particles, the PCR particles are prone to rubbing against each other, and the rubbing will generate powder and mix in the PCR particles. To improve the production quality of PCR particles, it is usually necessary to separate the PCR particles and the powder mixed therein. The existing separation treatment method is usually screening and filtering.

[0026] Referring to Figure 1 and Figure 2 , a PCR particle purification device, which includes a tank body 100, a steam generator 200 and a blowing mechanism 300. The tank body 100 has a purification inner cavity 101. The tank body 100 is connected with a first material pipe 110 and a second material pipe 120. The first material pipe 110 is used to input PCR particles into the purification inner cavity 101, and the second material pipe 120 is used to discharge the PCR particles in the purification inner cavity 101. A steam pipe 210 is provided between the steam generator 200 and the tank body 100 and is connected through the steam pipe 210. The steam generator 200 can generate steam and transport it to the purification inner cavity 101 through the steam pipe 210. The blowing mechanism 300 is connected with the tank body 100 and can blow air into the purification inner cavity 101. An exhaust pipe 130 is connected to the upper side of the tank body 100, and the exhaust pipe 130 is used to discharge the gas in the purification inner cavity 101.

[0027] It can be understood that as Figure 1 andFigure 2 As shown in the figure, during use, PCR particles are input into the purification cavity 101 through the first material pipe 110. The steam generator 200 generates steam and transports it to the purification cavity 101 through the steam pipe 210. The steam is used to adjust the humidity in the purification cavity 101, which helps reduce the generation of static electricity. Moreover, the water molecules in the steam can conduct electricity, which can increase the electrical conductivity of the air in the purification cavity 101, enabling the static charges on the PCR particles to be neutralized or dissipated, so as to eliminate the static electricity on the PCR particles. At the same time, the air supply mechanism 300 supplies air to the purification cavity 101 to form an air flow in the purification cavity 101. The steam flows in the purification cavity 101 along with the air flow and is discharged outward through the exhaust pipe 130 on the upper side of the tank body 100, so as to achieve a better purification treatment effect on the PCR particles. A switching valve 121 is provided on the second material pipe 120 to control the opening and closing of the second material pipe 120. The PCR particles after purification treatment in the purification cavity 101 can be discharged through the second material pipe 120 to subsequent processing equipment, which is convenient for subsequent separation of the PCR particles and the powder mixed therein and is convenient for production applications.

[0028] In actual application, the specific structure of the steam generator 200 can be set according to actual usage needs. Since the specific composition of the steam generator 200 in the embodiments of the present invention is known to those of ordinary skill in the art, it will not be described in detail here.

[0029] In some embodiments, the air supply mechanism 300 includes a hot air blower 310 and a hot air pipe 320. The hot air blower 310 is connected to the tank body 100 through the hot air pipe 320 and can transport hot air into the purification cavity 101.

[0030] It can be understood that, as shown in Figure 1 and Figure 2 , the hot air blower 310 is arranged on one side of the tank body 100 and is connected to the tank body 100 through the hot air pipe 320. During use, the hot air blower 310 transports hot air into the purification cavity 101 through the hot air pipe 320. The hot air flow passes through the PCR particles and heats the PCR particles, promoting the volatilization of the odor on the PCR particles and discharging it outward through the exhaust pipe 130 on the upper side of the tank body 100 along with the air flow, which can deodorize the PCR particles. Moreover, the hot air flow can reduce the possibility of steam condensing into water, facilitating the achievement of a better purification effect. In actual application, the specific structure of the hot air blower 310 can be set according to actual usage needs. Since the specific composition of the hot air blower 310 in the embodiments of the present invention is known to those of ordinary skill in the art, it will not be described in detail here.

[0031] Further, the connection position between the steam pipe 210 and the tank body 100 is located on the lower side of the purification inner cavity 101. A hot air shell 330 is provided in the purification inner cavity 101. The hot air shell 330 is arranged on the lower side of the purification inner cavity 101 and is provided with a hot air cavity 301 with an opening facing downward. The hot air pipe 320 is connected to the hot air shell 330 to be able to deliver hot air to the hot air cavity 301.

[0032] It can be understood that, as Figure 1 and Figure 2 shown, the connection position between the steam pipe 210 and the tank body 100 and the hot air shell 330 are both arranged on the lower side of the purification inner cavity 101. Thus, the steam output from the steam pipe 210 and the hot air output from the hot air cavity 301 both flow upward from the lower side of the purification inner cavity 101, enabling the steam and hot air flows to better flow through the PCR particles in the purification inner cavity 101 and achieving a better purification effect; the opening of the hot air cavity 301 faces downward, which can reduce the possibility of PCR particles in the purification inner cavity 101 entering the hot air pipe 320 and ensure the normal operation of the hot air blower 310. In actual application, to prevent PCR particles from entering the interior of the steam pipe 210, a protective shell or filter screen can be provided at the outlet of the steam pipe 210 to block PCR particles from entering the interior of the steam pipe 210, which can be specifically set according to actual usage needs.

[0033] Further, the outlet position of the steam pipe 210 is located above the opening position of the hot air cavity 301 in the vertical direction. It can be understood that, as Figure 1 and Figure 2 shown, the hot air output from the hot air cavity 301 will form an upward flowing air current in the purification inner cavity 101. By setting the outlet position of the steam pipe 210 higher than the opening position of the hot air cavity 301, this design is beneficial to preventing the steam output from the steam pipe 210 from entering the hot air cavity 301 and enabling the hot air flow to better carry the steam and flow upward together, facilitating the achievement of a better purification effect. In actual application, the outlet position of the steam pipe 210 and the opening position of the hot air cavity 301 can be set accordingly according to actual usage needs.

[0034] Further, the hot air shell 330 has a cylindrical structure and extends in the vertical direction. The upper end of the hot air shell 330 is a closed end, and the connection position between the hot air pipe 320 and the hot air shell 330 is located on the upper side of the hot air shell 330.

[0035] It can be understood that, as Figure 1 and Figure 2As shown, the hot air shell 330 has a cylindrical structure and extends in the vertical direction. The upper end of the hot air shell 330 is a closed end, and the lower end of the hot air shell 330 is the opening end of the hot air chamber 301. The connection position between the hot air pipe 320 and the hot air shell 330 is located on the upper side of the hot air shell 330. Such a design is beneficial to reducing the possibility of PCR particles in the purification inner cavity 101 entering the hot air pipe 320 from the hot air chamber 301, ensuring the normal operation of the hot air blower 310.

[0036] Further, the lower end of the hot air shell 330 has a flared structure. It can be understood that, as Figure 2 shown, by setting the lower end of the hot air shell 330 to have a flared structure, the outlet area of the hot air chamber 301 can be increased, the flow range of the hot air in the lower part of the purification inner cavity 101 can be enlarged, which is convenient for purification. In actual application, the specific structure of the hot air shell 330 can be set according to actual usage requirements.

[0037] In some embodiments, the PCR particle purification device further includes a driver 400 and a conveying assembly 500. The driver 400 is drivingly connected to the conveying assembly 500. The conveying assembly 500 is disposed in the purification inner cavity 101 and is used to convey the PCR particles in the lower part of the purification inner cavity 101 to the upper part of the purification inner cavity 101.

[0038] It can be understood that, as Figure 1 and Figure 2 shown, the driver 400 is disposed outside the tank body 100, the conveying assembly 500 is disposed in the purification inner cavity 101, and the driver 400 is drivingly connected to the conveying assembly 500 to drive it to operate. During use, the conveying assembly 500 conveys the PCR particles in the lower part of the purification inner cavity 101 to the upper part of the purification inner cavity 101, so that the PCR particles in the purification inner cavity 101 circulate up and down, improving the uniformity of the PCR particles in the tank body 100. Thus, it is beneficial for the steam and hot air to contact the PCR particles, enabling the PCR particles in the purification inner cavity 101 to be heated evenly and contact the steam evenly, which is convenient for purification. In actual application, in addition to the above structure, a stirring assembly can also be provided in the purification inner cavity 101. By rotating the stirring assembly, the PCR particles in the purification inner cavity 101 are stirred to make the PCR particles in the purification inner cavity 101 heated evenly and contact the steam evenly. Specifically, it can be set according to actual usage requirements.

[0039] Further, the conveying assembly 500 includes a conveying pipe 510 and a rotating shaft member 520. The conveying pipe 510 is arranged in the vertical direction. The lower end of the conveying pipe 510 is provided with a feeding port 501 for PCR particles to enter, and the upper end of the conveying pipe 510 is provided with a discharging port 502 for PCR particles to output. The rotating shaft member 520 is arranged inside the conveying pipe 510 and is provided with a spiral blade 521 to define a spiral conveying channel between the rotating shaft member 520 and the inner wall of the conveying pipe 510. The driver 400 is drivingly connected to the rotating shaft member 520 to drive the rotating shaft member 520 to rotate.

[0040] It can be understood that, as Figure 2 shown, the conveying pipe 510 is arranged vertically in the up and down direction. The rotating shaft member 520 is arranged inside the conveying pipe 510 and is provided with a spiral blade 521 to define a spiral conveying channel (not marked in the figure) between the rotating shaft member 520 and the inner wall of the conveying pipe 510. During use, the PCR particles in the purification cavity 101 enter the conveying channel inside the conveying pipe 510 through the feeding port 501 at the lower end of the conveying pipe 510. The driver 400 drives the rotating shaft member 520 to rotate, driving the spiral blade 521 to rotate, so that the PCR particles in the conveying channel are lifted and conveyed upward. After the PCR particles in the conveying channel are conveyed to the upper end of the conveying pipe 510, they are output through the discharging port 502 and then fall back to the lower part of the purification cavity 101 again. The structure is simple and convenient to use. In practical applications, the conveying assembly 500 can also be a crawler-type conveying structure or an up-and-down flipping conveying structure, which can be changed accordingly according to actual use needs.

[0041] In some embodiments, the lower side wall portion of the tank body 100 is in an inverted conical structure. It can be understood that, as Figure 1 and Figure 2 shown, by setting the lower side wall portion of the tank body 100 to be in an inverted conical structure, it is beneficial for the PCR particles at the lower part of the purification cavity 101 to converge at the lower end of the conveying assembly 500, so that they enter the feeding port 501 of the conveying assembly 500, which is convenient to use. In practical applications, the specific structure of the tank body 100 can be set accordingly according to actual use needs.

The auxiliary feed bin 140 is provided with a switchable door body (not shown in the figure). The first feed pipe 110 is connected to the tank body 100 through the auxiliary feed bin 140.

[0043] It can be understood that, as Figure 1 and Figure 2As shown, an auxiliary bin 140 is connected to the lower side of the tank body 100. The interior of the auxiliary bin 140 communicates with the lower part of the purification cavity 101. The first material pipe 110 is connected to the tank body 100 through the auxiliary bin 140. During use, the PCR particles input through the first material pipe 110 enter the auxiliary bin 140 and then enter the lower part of the purification cavity 101 via the auxiliary bin 140. By providing the auxiliary bin 140, the purification cavity 101 can be supplemented with and partially output PCR particles by opening and closing the door body on the auxiliary bin 140, so as to sample or observe the PCR particles in the purification cavity 101 to understand the treatment situation of the PCR particles in the purification cavity 101, or the lower part of the purification cavity 101 can be cleaned through the auxiliary bin 140.
