[0023] The preferred embodiment of the utility model; Figure 1-Figure 5 As shown, a cargo shower channel for a clean room, the channel includes a channel body 10, the channel body 10 is arranged at the entrance of the clean room, so that the cargo entering the clean room can be cleaned through the cargo shower channel, the channel body 10 has an outlet and an inlet, the outlet is connected to the entrance of the clean room, the inlet and the outlet are arranged opposite to each other, that is, the inlet of the channel is used for the cargo to enter the channel from the external environment, and the outlet of the channel is used for the cargo to enter the clean room from the channel.
[0024] A door-like structure is provided at the entrance and the exit of the channel body 10 (the door-like structure is not shown in the figure). The door-like structure can adopt the automatic door commonly used in the prior art. The door-like structure closes the channel body 10 to ensure that the inside of the channel body is isolated from the outside to prevent the processed goods from being contaminated by the external environment again. The door-like structures of the entrance and exit cannot be opened at the same time to ensure.
[0025] The cargo shower channel also includes a blowing dust removal mechanism 20 and an exhaust dust removal mechanism 30. The blowing dust removal mechanism 20 blows airflow to the cargo entering the channel body 10 to blow away the dust on the surface of the cargo. The exhaust dust removal mechanism 30 is used to discharge the dust-containing airflow inside the channel body 10 from the channel body 10. The blowing dust removal mechanism 20 and the exhaust dust removal mechanism 30 are respectively arranged on both sides between the outlet and the inlet of the channel body 10, so that the blowing dust removal mechanism 20 and the exhaust dust removal mechanism 30 are arranged opposite to each other. When the cargo is dusted, the blowing dust removal mechanism 20 blows away the dust on the cargo entering the channel body 10 and staying in the middle of the channel body 10, and the exhaust dust removal mechanism 30 extracts the dust separated from the cargo from the cargo shower channel. The dust-containing airflow extracted by the exhaust dust removal mechanism 30 is processed by an external dust removal device and discharged into the atmosphere.
[0026] In order to increase the airflow range blown out by the blowing dust removal mechanism, the blowing dust removal mechanism 20 is rotatably arranged in the middle of the top of the channel main body 10, and the blowing part of the blowing dust removal mechanism 20 is arranged close to one of the side walls of the channel main body 10, and the blowing direction of the blowing part is toward the exhaust dust removal mechanism 30, so that the dust separated from the cargo can quickly enter the exhaust dust removal mechanism 30 under the action of the separation inertia and the exhaust dust removal mechanism 30.
[0027] In this embodiment, the blowing and dust removing mechanism 20 includes a rotating shaft 201, a pulley 202 is fixedly connected to the upper end of the rotating shaft 201, and an L-shaped arm 203 is fixedly connected to the lower end, the L-shaped arm 203 includes a transverse arm 2031 and a longitudinal arm 2032, the transverse arm 2031 is fixedly connected to the rotating shaft 201, and the longitudinal arm 2032 is an air outlet; the rotating shaft 201, the transverse arm 2031 and the longitudinal arm 2032 are hollow inside to form a connected air duct, and the longitudinal arm 2032 is provided with a plurality of blowing nozzles 205, and the rotating shaft 201 is located outside the channel and is provided with an air pipe connector 204, and the air pipe connector 204 is rotatable relative to the rotating shaft. Specifically, the end of the air pipe connector 204 is bent outward to form a convex ring to ensure that the air pipe connector 204 will not fall off when inserted into the rotating shaft, and the end of the air pipe connector is connected to an external air source through an air pipe to provide airflow into the air duct.
[0028] Specifically, a driving motor 1 is arranged on the outer side of the top of the channel main body 10, and the driving motor 1 is preferably a servo motor. A driving wheel is fixedly arranged on the output shaft of the driving motor 1, and a driving belt is mounted on the driving wheel and the pulley, so that the air blowing and dust removal mechanism is driven by the motor to rotate within a certain angle range, and the certain angle range here is between 45° and -45°. In this way, it can be ensured that within the rotation range of the air blowing and dust removal mechanism, the blowing part is always facing or obliquely facing the direction of the exhaust dust removal part.
[0029] It should be noted that at least two rows of blowing nozzles 205 are provided on the longitudinal arm 2032, and each row of blowing nozzles includes a first blowing nozzle 2051 and a second blowing nozzle 2052, wherein the first blowing nozzle 2051 and the second blowing nozzle 2052 are spaced apart along the length direction of the longitudinal arm 2032, and the blowing directions of the first blowing nozzle 2051 and the second blowing nozzle 2052 are symmetrical, so that the blowing direction of the first blowing nozzle 2051 is inclined toward the inlet side, and the blowing direction of the second blowing nozzle 2052 is inclined toward the outlet side, so that the airflow will be evenly blown away from both sides of the goods during the blowing process, and a huge gap between the airflow on one side and the other side will not be caused, resulting in a ring-shaped backflow around the goods.
[0030] In order to ensure that the rotation angle of the blowing and dust removal mechanism is within the above range, a symmetrically arranged cross arm limit terminal 101 is provided on the top of the channel body 10. The cross arm limit terminal 101 ensures that the blowing part of the blowing and dust removal mechanism 20 is always opposite to the exhaust dust removal mechanism 30.
[0031] In this embodiment, the exhaust dust removal mechanism 30 is arranged on the side opposite to the blowing part, and the exhaust dust removal mechanism 30 includes a funnel for collecting dust, and the inlet of the funnel faces the interior of the channel body. An exhaust fan is arranged at the end of the funnel (the specific structure of the exhaust fan is not shown in the figure). The exhaust fan draws air to form an airflow from the inside of the channel to the outside of the channel, which is more conducive to the rapid discharge of the dust-containing airflow inside the channel body.
[0032] At the same time, a check valve is arranged between the end of the funnel and the exhaust fan (the figure shows that the check valve here is a common kitchen fume check valve) to prevent the external airflow from entering the cargo shower channel in a non-working state.
[0033] As a supplementary solution to the above-mentioned embodiment, the cargo shower channel also includes a lifting assembly 40, which includes a base 401 and a hydraulic cylinder 402 arranged inside the base. The base 401 is fixedly arranged at the bottom of the channel body 10, and a lifting platform 403 can be arranged at the end of the piston rod of the hydraulic cylinder 402. When in use, the hydraulic cylinder 402 lifts the lifting platform 403 to ensure that goods at different heights can be completely within the blowing area of the blowing part.
[0034] It should be noted that the lifting platform 403 includes a fixed platform 4031 and a rotating platform 4032. The fixed platform 4031 is fixedly connected to the piston rod of the hydraulic cylinder 402. A rotating motor 404 is arranged at the center position below the fixed platform 4031. The output shaft of the rotating motor 404 passes through the fixed platform 4031 and is fixedly connected to the rotating platform 4032 on the upper side of the fixed platform 4031, so as to drive the rotating platform 4032 to rotate through the rotating motor 404. When in use, the rotating platform 4032 rotates so that each side of the cargo can be opposite to the blowing part.
[0035] In order to ensure the stability of the rotating table, opposite annular grooves 4033 are provided on the upper surface of the fixed table 4031 and the lower surface of the rotating table 4032. A plurality of balls for supporting the rotating table 4032 are arranged in the annular grooves 4033. When the rotating table 4032 rotates, the balls can provide support for the periphery of the rotating platform 4032.
