Description

Technical Field

[0001] The utility model belongs to the technical field of air shower rooms, and particularly relates to an air shower room for rapid dust removal. Background Art

[0002] An air shower room is a general-purpose local purification device installed between a clean room and a non-clean room. It is a necessary passage to enter the clean room and can reduce the pollution problems brought by entering and leaving the clean room. When people and goods need to enter the clean area, they need to be blown by the air shower room. The clean air blown out can remove the dust carried by people and goods and effectively block or reduce the dust source from entering the clean area. The front and rear doors of the air shower room / cargo shower room are electronically interlocked and can also act as an air lock to prevent unpurified air from entering the clean area.

[0003] In the process of implementing the present utility model, the inventor found that there are at least the following problems in this technology: In the existing air shower rooms, such as the patent with the application number CN202322454249.7 - an air shower room for rapid dust removal, when removing dust, the high - speed air flow blown by the fan is usually uncontrollable. This leads to the need for the high - speed fan to run for a long time to achieve dust removal work at different positions and different heights of the human body, thus prolonging the required time, reducing the dust removal efficiency, and resulting in incomplete dust removal.

[0004] Therefore, we propose an air shower room for rapid dust removal to solve the above problems. Content of the Utility Model

[0005] The main purpose of the present utility model is to provide an air shower room for rapid dust removal, which adapts to the dust removal work at different positions of the human body, realizes faster dust removal, makes the dust removal work more comprehensive, and can effectively solve the problems in the background art.

[0006] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0007] An air shower room for rapid dust removal includes a base and a protective cover integrally welded above the base. The interior of the whole formed by the base and the protective cover is designed to be hollow, thus forming the chamber body of the air shower room. Two air ducts are respectively formed on the opposite side walls of the protective cover. There are a total of four air ducts, and high - speed fans are installed in all four air ducts.

[0008] On both sides of the top wall of the base, side supports are respectively welded, and the two side supports are close to one of the high - speed fans. A first motor is vertically installed on one of the side supports, and side grooves are respectively formed on the opposite sides of the two side supports. A screw rod and a sliding rod are respectively arranged in the two side grooves. The output shaft of the first motor is coaxially connected to the screw rod, and both sides of the sliding rod are welded to the side supports.

[0009] A lifting platform is also provided between the two side supports. One side of the lifting platform is threadedly sleeved on the screw rod, and the other side is slidably sleeved on the sliding rod. The overall shape of the lifting platform is in a square shape with openings on four sides. The two sides of the lifting platform extend horizontally and are connected to the screw rod and the sliding rod. A second motor is horizontally installed on one side wall of the lifting platform. A plurality of inner support shafts are rotatably connected inside the lifting platform. The output shaft of the second motor is coaxially connected to one of the inner support shafts. Chain wheels are respectively and fixedly sleeved on the plurality of inner support shafts, and the plurality of chain wheels are connected by a chain. Guide vanes for guiding the high-speed air flow blown by the high-speed air blower are respectively welded on the plurality of inner support shafts, so that the high-speed air flow blown out from the inside of the lifting platform can change the wind direction under the guidance of the plurality of guide vanes, and thus the high-speed air flow can be used to adapt to a larger range of dust removal work.

[0010] As a preferred implementation, openings are provided on both sides of the protective cover, and the two openings on the protective cover are respectively an inlet and an outlet. Side doors are respectively connected to the two openings on the protective cover through hinges; on the opposite sides of the two side doors, U-shaped handles are respectively connected, which is convenient for personnel to hold the handles to flip the side doors, so that they can enter the protective cover from the inlet and go out from the outlet after the dust removal work is completed.

[0011] As a preferred implementation, dust-proof nets are installed on both sides of each air duct opening; through the design of the dust-proof nets, the high-speed air blower can be isolated, preventing external objects or the human body from entering the air duct and being damaged by the high-speed air blower, and at the same time, the high-speed air blower can be protected to reduce dust ingress.

[0012] As a preferred implementation, both the screw rod and the sliding rod are vertically arranged, and the screw rod and the sliding rod are symmetric with respect to the two sides of the lifting platform. Both sides of the screw rod are rotatably connected to the side supports; this enables the screw rod to operate stably under the drive of the first motor. The high-speed air blower, the first motor, and the second motor all require external power facilities for power supply.

[0013] As a preferred implementation, the plurality of inner support shafts are equidistantly distributed in the vertical direction inside the lifting platform; this enables the guide vanes on the plurality of inner support shafts to be equidistantly distributed, and no matter what angle the plurality of guide vanes are flipped to, they are parallel to each other.

[0014] As a preferred implementation, the high-speed air blowers on both sides of the protective cover are both horizontally arranged and have the same wind direction; thus, the high-speed air blower on the side of the protective cover close to the two side supports is used for air intake, and the high-speed air blower on the other side is used for air outlet, realizing the rapid input and output of air and achieving rapid dust removal work.

[0015] In summary, the technical effects and advantages of the present utility model are as follows:

[0016] The air shower room for rapid dust removal drives a plurality of guide vanes to flip to a suitable angle by driving the second motor to operate, and continuously adjusts this angle, so that the air blown out by the high-speed blower can be guided to different directions, blow air from different angles of the human body, making the dust removal effect better. By operating the first motor, the height of the guide vanes can be adjusted, thus adapting to the dust removal work at different positions of the human body, achieving faster dust removal, and making the dust removal work more comprehensive;

[0017] When the second motor of the air shower room for rapid dust removal operates, it drives the inner support shaft connected to it and the sprocket on it to rotate. The remaining inner support shafts can be rotated by using the chain, so that a plurality of guide vanes flip synchronously, so that a plurality of guide vanes tilt upward or downward to remove dust at different heights of the human body. The first motor can also be driven to operate to drive the screw rod to rotate, so that the lifting platform rises and falls along the sliding rod, adjusting the height of a plurality of guide vanes, thereby further expanding the dust removal range and facilitating the faster realization of the dust removal work.
