[0026] Referring to Figure 1 and Figure 2 , a PCR particle deodorization reactor, which includes a tank body 100 and a hot air blower 300. The tank body 100 has a deodorization inner cavity 101. The tank body 100 is connected with a feeding pipe 110 and a first discharging pipe 120. The feeding pipe 110 is used to input PCR particles into the deodorization inner cavity 101, and the first discharging pipe 120 is used to discharge the PCR particles in the deodorization inner cavity 101. A hot air hood 200 is arranged in the deodorization inner cavity 101. The hot air hood 200 is arranged on the lower side of the deodorization inner cavity 101 and has a hot air cavity 201 with an opening facing downwards. The hot air blower 300 is arranged on one side of the tank body 100. The tank body 100 is connected with a hot air pipe 140. The hot air blower 300 is connected with the hot air hood 200 through the hot air pipe 140 and can convey hot air into the hot air cavity 201. The upper side of the tank body 100 is connected with an exhaust pipe 150, and the exhaust pipe 150 is used to discharge the gas in the deodorization inner cavity 101.
[0027] It can be understood that as Figure 1 and Figure 2As shown, the tank body 100 is vertically arranged in the up and down direction. The feeding pipe 110 is connected to the upper side of the tank body 100 to facilitate the input of PCR particles. The first discharging pipe 120 is connected to the lower side of the tank body 100 to facilitate the discharge of PCR particles in the deodorizing cavity 101. The hot air hood 200 is arranged on the lower side of the deodorizing cavity 101 and the opening of the hot air cavity 201 faces downward. Such a design can reduce the possibility of PCR particles in the deodorizing cavity 101 entering the hot air pipe 140 from the hot air cavity 201 and ensure the normal operation of the hot air blower 300. During use, PCR particles are input into the deodorizing cavity 101 through the feeding pipe 110. The hot air blower 300 conveys hot air into the hot air cavity 201 of the hot air hood 200 through the hot air pipe 140. Since the hot air hood 200 is arranged on the lower side of the deodorizing cavity 101 and the opening of the hot air cavity 201 faces downward, and the exhaust pipe 150 is connected to the upper side of the tank body 100, the hot air output from the hot air cavity 201 flows upward from the lower side of the deodorizing cavity 101.

The PCR particles after the deodorization treatment can be discharged from the deodorizing cavity 101 through the first discharging pipe 120. The structure of the present utility model is simple and reasonable, can better realize the deodorization treatment of PCR particles, consumes less material cost, and is convenient for production and application.

[0030] It can be understood that by setting the material leveling mechanism and using the material leveling mechanism to drive the PCR particles in the deodorizing cavity 101 to flow, the uniformity of the PCR particles in the tank body 100 can be improved, the PCR particles in the deodorizing cavity 101 can be heated evenly, which is beneficial to the progress of the deodorization treatment and realizes a better deodorization effect. During actual application, the specific structure of the material leveling mechanism can be set accordingly according to actual use needs and will not be described in detail here. Specific description will be made below.

During use, the conveying assembly 500 conveys the PCR particles in the lower part of the deodorizing inner cavity 101 to the upper part of the deodorizing inner cavity 101, so that the PCR particles in the deodorizing inner cavity 101 circulate up and down, improving the uniformity of the PCR particles in the tank body 100. In practical applications, in addition to the above structure, the material leveling mechanism may further include a stirring assembly. The driver 400 is drivingly connected to the stirring assembly to drive the stirring assembly to rotate and stir the PCR particles in the deodorizing inner cavity 101 to achieve the effect of making them flow, which can be specifically set according to actual usage needs.
[0033] In some embodiments, 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 rotating shaft member 520 is disposed 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 inner wall of the conveying pipe 510. During use, the PCR particles in the deodorizing inner 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 deodorizing inner cavity 101 again. The structure is simple and convenient to use.

In actual application, a stirring mechanism can be arranged on the lower side of the tank body 100, and the stirring mechanism is used to stir the PCR particles in the lower part of the deodorizing inner cavity 101 to prevent them from caking, so as to facilitate the conveying assembly 500 to convey the PCR particles, and it can be specifically set according to actual use needs.

[0037] In some embodiments, the hot air hood 200 has a cylindrical structure and extends in the vertical direction.

[0039] Furthermore, the lower end of the hot air hood 200 has a flared structure.
