Description

Technical Field

[0001] The utility model relates to the technical field of fresh air systems, in particular to a lifting room convection system. Background Art

[0002] In the field of workpiece coating, after the workpiece is sprayed, it enters the drying room for curing to solidify the paint layer sprayed on the surface of the workpiece, and finally passes through the baking room to eliminate stress and other processes. With the development of industry, manual transportation after the workpiece is sprayed is less and less. Mobile equipment is usually used to transfer the workpiece. Commonly used mobile equipment includes conveyor belts, hoists, elevators, etc. However, in the process of transferring the workpiece, the paint layer on the surface of the workpiece has a strong adsorption capacity before it solidifies (before curing). As a result, in the process of moving the workpiece, the dust in the air or the dust generated by the mobile device during operation will be adsorbed onto the surface of the paint layer, resulting in spots on the surface of the dried paint layer, affecting the quality of the entire spraying.

[0003] The most common processing method is to move the workpiece in the clean room. For example, the publication number CN218981995U discloses a clean room system with high efficiency dehumidification, including: a clean room, the upper end of which is laterally provided with an air intake balancing device for balancing the airflow flowing into the room, and the bottom of the clean room is correspondingly provided with a return air balancing device for balancing the airflow out of the room; an air conditioning system, which is connected to the upper and lower ends of the clean room at the same time, and the airflow flows evenly from top to bottom through the internal space of the clean room, and flows back to the air conditioning system to form an airflow cycle; a refrigeration system, which is connected to the air conditioning system, and regulates the temperature and humidity of the clean room through heat exchange; wherein, a heat recovery device is installed on the refrigeration system, which is used to heat the return air of the clean room, and the heated return air passes through the dehumidification device to further reduce the humidity of the indoor air. In the above scheme, the air flows from the top of the clean room to the bottom of the clean room. At the same time, air intake balancing devices are provided at both the upper and lower ends. However, when the mobile device drives the workpiece to move up and down or horizontally in the clean room, since the air moves from top to bottom, the dust generated by the moving device can be more easily adsorbed onto the paint layer on the surface of the workpiece. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a lifting chamber convection system which can prevent dust in the air from adhering to the surface of the workpiece during the movement of the sprayed workpiece.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a lifting chamber convection system, including a lifting main chamber arranged in the lifting chamber for moving workpieces and a lifting auxiliary chamber for installing an elevator, an air supply port is provided at the bottom of the lifting main chamber, and an air exhaust port is provided at the top of the lifting auxiliary chamber, and the air in the lifting chamber flows from the bottom of the lifting main chamber to the top of the lifting auxiliary chamber.

[0006] As a preferred embodiment of the present invention, a partition is provided in the lifting chamber, which divides the lifting chamber into a main lifting chamber and a sub-lifting chamber. An installation groove connecting the main lifting chamber and the sub-lifting chamber is provided on the partition, and the installation groove is located in the main lifting chamber; the elevator lifts the workpiece from the bottom of the main lifting chamber to the top of the main lifting chamber.

[0007] As a preferred embodiment of the utility model, an air supply chamber is arranged on the side wall of the lifting main chamber, a medium-efficiency filter is arranged in the air supply chamber, and a medium-efficiency power device is fixedly installed at the air supply outlet.

[0008] As a preferred embodiment of the utility model, the air outlet is connected with an air duct, the end of the air duct is connected with a circulating fan, the air inlet of the circulating fan is connected with the air outlet; the air outlet of the circulating fan is connected with the air supply chamber.

[0009] As a preferred embodiment of the present invention, an air handler is further arranged between the exhaust port and the circulating fan, the air inlet of the air handler is through-connected with the air supply port, and the air outlet of the air handler is through-connected with the air inlet of the circulating fan.

[0010] As a preferred embodiment of the present invention, a butterfly valve is provided between the exhaust port and the circulating fan or between the air supply box and the circulating fan.

[0011] The beneficial effects of the utility model are as follows: 1. The elevator is arranged in the lifting sub-chamber, and the workpiece moves in the lifting main chamber under the action of lifting, which prevents the dust generated by the elevator during operation from entering the lifting main chamber and adhering to the surface of the workpiece, thereby affecting the overall spraying quality of the workpiece.

[0012] 2. By setting an air supply port at the bottom of the main lift chamber and an air exhaust port at the top of the auxiliary lift chamber, air enters the lift chamber from the air supply port at the bottom of the main lift chamber, passes through the mounting groove on the partition plate and enters the auxiliary lift chamber, and then is discharged to the outside of the lift chamber from the air exhaust port at the top of the auxiliary lift chamber, so that the air in the lift chamber flows from the bottom of the main lift chamber to the top of the auxiliary lift chamber. Thus, the dust floating in the air in the lift chamber and the dust generated when the lift is working are discharged to the outside of the lift chamber along with the flow of air. This further prevents the dust in the air in the lift chamber and the dust generated when the lift is working from adhering to the surface of the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] See also Figure 1-2 As shown, the utility model relates to a lifting chamber convection system, wherein a partition 02 is arranged in the lifting chamber 01, and the partition 02 divides the lifting chamber 01 into a lifting main chamber 03 and a lifting auxiliary chamber 04, and a mounting groove 05 connecting the lifting main chamber 03 and the lifting auxiliary chamber 04 is arranged on the partition 02, and an elevator 06 is installed in the lifting auxiliary chamber 04, and the pins on the elevator 06 pass through the mounting groove 05 and are located in the lifting main chamber 03. The workpiece is placed on the pins of the elevator 06, and the workpiece is lifted from the bottom of the lifting main chamber 03 to the top of the lifting main chamber 03 by the elevator 06. The design of the partition 02 prevents the dust generated by the elevator 06 during operation from entering the lifting main chamber 03 and adhering to the surface of the workpiece, thereby affecting the overall spraying quality of the workpiece. The bottom of the main lifting chamber 03 is provided with an air supply port 07, and the top of the auxiliary lifting chamber 04 is provided with an air exhaust port 08. The air enters the lifting chamber 01 from the air supply port 07 at the bottom of the main lifting chamber 03, passes through the mounting slot 05 on the partition 02, and enters the auxiliary lifting chamber 04. Then, it is discharged to the outside of the lifting chamber 01 from the air exhaust port 08 at the top of the auxiliary lifting chamber 04, so that the air in the lifting chamber 01 flows from the bottom of the main lifting chamber 03 to the top of the auxiliary lifting chamber 04. Thus, the dust floating in the air in the lifting chamber 01 is discharged to the outside of the lifting chamber 01 along with the flow of air. Thus, the moving direction of the workpiece is the same as the flow direction of the air, thereby further preventing the dust in the air in the lifting chamber 01 from adhering to the surface of the workpiece.

[0018] In order to prevent dust in the air from entering the main lift chamber 03 from the air supply port 07 again, an air supply chamber 09 is provided on the side wall of the main lift chamber 03, a medium efficiency filter 10 is provided in the air supply chamber 09, and a medium efficiency filter is fixedly installed at the air supply port 07. The air separates the dust in the air in the air supply chamber 09 under the action of the medium efficiency filter 10, preventing the dust in the air from entering the main lift chamber 03 of the equipment.

[0019] In order to make the air in the lifting room 01 have a moving flow speed, an air duct 11 is connected to the exhaust port 08, and a circulating fan is connected to the end of the air duct 11, and the air inlet of the circulating fan is connected to the exhaust port 08. The air outlet 08 of the circulating fan is connected to the air supply chamber 09. When the circulating fan is started, the air in the lifting room 01 is sucked out from the exhaust port 08, and fresh air is sent into the lifting room 01, so that the air flows in the lifting room 01.

[0020] Since the workpieces in the lifting chamber 01 are all just finished spraying, they will emit pungent gas. In order to make the air sent into the lifting chamber 01 free of odor, an air handler is also arranged between the exhaust port 08 and the circulating fan. The air inlet of the air handler is connected to the air supply port, and the air outlet of the air handler is connected to the air inlet of the circulating fan. When the circulating fan draws the air in the lifting chamber 01 from the exhaust port 08, the air handler will process the odor in the air, so that the air entering the lifting chamber 01 does not have any odor.

[0021] In order to prevent the air from flowing too fast in the lifting chamber 01, a butterfly valve is provided between the exhaust port 08 and the circulating fan or between the air supply box and the circulating fan. The speed of the air flow in the lifting chamber 01 is controlled by controlling the opening angle of the butterfly valve.
