Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil immersion equipment, and specifically to a drying device. Background Technology
[0002] To prevent parts from rusting, an oil immersion treatment is typically used. This involves placing the parts in a container filled with oil, using the oil to cover the surface and isolate them from corrosive agents. However, after immersion, excess oil remains on the surface, requiring drying before packaging. To achieve rapid drying, current technology involves placing the parts in a closed space and using air knives to blow strong air to quickly remove the oil. The closed space is used to prevent the oil from being carried away by the strong airflow, thus contaminating the air and environment of the production workshop. However, in practice, whenever parts need to be moved into or out of this closed space, exhaust gases containing oil mist and other potential pollutants inevitably leak into the workshop environment. These exhaust gases not only negatively impact the air quality of the workshop but also pose a potential threat to workers' respiratory system and other health conditions. Utility Model Content
[0003] Based on this, and in response to the above problems, this utility model provides a drying device.
[0004] The objective of this utility model can be achieved through the following technical solutions:
[0005] A drying device for drying parts that have been soaked in oil includes a housing, a conveying mechanism with a bottom of the housing, and a blower mechanism located above the conveying mechanism inside the housing. The housing has an inlet at the rear end of its top and an outlet at its front end. Gates are provided at both the inlet and outlet inside the housing. The device also includes a waste gas recovery mechanism, which includes suction nozzles located at the inlet and outlet respectively. The inner surface of each suction nozzle has an air intake. All suction nozzles are connected to a blower located on one side of the housing via pipes. A filter is connected to the outlet of the blower.
[0006] Using the above technical solution, when oil-soaked parts enter the housing and are positioned on the conveying mechanism, the strong airflow from the air knife located on the upper side of the conveying mechanism blows away the oil on the surface of the parts, thereby accelerating the drying process, reducing production time, and ultimately lowering costs. Furthermore, the closure of the two gates creates a sealed space inside the housing, preventing the oil from being carried away by the strong airflow and avoiding pollution of the air and environment in the production workshop. By installing suction nozzles at the inlet and outlet, when the inlet or outlet gate is opened, the exhaust gas, under the negative pressure generated by the blower, enters the filter through the suction nozzle and air pipe. The oil vapor in the exhaust gas is intercepted by the filter bag, while the clean air is directly discharged into the atmosphere, thus preventing pollution of the workshop environment.
[0007] In a specific embodiment of this utility model: the suction nozzle has a U-shaped structure.
[0008] In a specific embodiment of this utility model: the blower mechanism is an air knife, which has an air outlet facing the lower conveying mechanism, and a fan is connected to one side of the air knife.
[0009] In a specific embodiment of this utility model: it also includes a controller. Two horizontal cylinders are installed inside the housing. Two gates are respectively installed on the piston rod ends of the corresponding horizontal cylinders. A part detection sensor is provided next to the inlet of the housing. A stop plate and a position sensor are provided at the front end of the conveying mechanism. The two horizontal cylinders, the part detection sensor, the position sensor and the blower are all electrically connected to the controller.
[0010] In a specific embodiment of this utility model: the conveying mechanism is a roller conveyor driven by a motor, and the roller conveyor includes multiple rollers spaced apart along the forward direction of the parts.
[0011] In a specific embodiment of this utility model: an oil receiving tray is provided below the conveying mechanism. With this structure, the oil blown away is collected in the oil receiving tray and can be reused, thereby saving oil.
[0012] In summary, this invention places the oil-soaked parts on a conveying mechanism. Strong airflow from an air knife located above the conveying mechanism blows away the oil from the parts' surface, accelerating drying, reducing production time, and lowering costs. The blown-away oil is collected in an oil collection tray for recycling, thus saving oil. The sealed space within the housing prevents oil from being carried away by the wind, avoiding pollution of the production workshop's air and environment, and further reducing oil consumption. When the inlet or outlet gate is opened, the exhaust gas inside the housing, under the negative pressure generated by the blower, enters the filter through the suction nozzle and air pipe. The oil in the exhaust gas is intercepted by the filter bag, while the clean air is directly discharged into the atmosphere, thus achieving effective exhaust gas treatment and environmentally friendly emissions.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1 and Figure 2 As shown, this utility model is a drying device for drying parts that have undergone oil impregnation. It includes a housing 10, a conveying mechanism 20 housed within the housing 10, and a blower mechanism located above the conveying mechanism 20 within the housing. The blower mechanism is an air knife 30. The air knife 30 has an air outlet 31 facing downwards towards the conveying mechanism, and a fan 32 is connected to one side of the air knife 30. In this embodiment, there are four air knives 30, spaced apart above the conveying mechanism.
[0020] like Figure 2 and Figure 3 As shown, the housing 10 has an inlet 101 at its top rear end and an outlet 102 at its top front end. Gates 11 are provided inside the housing 10 at both the inlet 101 and the outlet 102 for opening or closing these points. Two horizontal cylinders 12 are installed inside the housing 10, and the two gates 12 are respectively mounted on the piston rod ends of the corresponding horizontal cylinders 12. Thus, the horizontal cylinders 12 drive the gates 11 to move horizontally, thereby controlling the opening or closing of the inlet 101 or the outlet 102. When both gates 11 are closed, a sealed space is formed inside the housing.
[0021] like Figure 3 As shown, it also includes a controller (not shown in the figure). A part detection sensor is provided next to the housing inlet 101. A stop plate 21 and a position sensor 22 are provided at the front end of the conveying mechanism 20. The two horizontal cylinders 12, the part detection sensor, and the position sensor 22 are all electrically connected to the controller.
[0022] In this embodiment, an oil receiving tray 15 is provided below the conveying mechanism 20. With this structure, the oil blown away from the parts inside the housing is collected through the oil receiving tray and can be recycled, thereby saving oil.
[0023] In this way, the oil-soaked parts are conveyed to the conveyor mechanism 20. The horizontal cylinder 12 at the inlet 101 drives the corresponding gate 11 to move and close the inlet 101. Subsequently, the conveyor mechanism 20 carries the parts towards the outlet 102. During the movement, the strong wind blown by the air knife located above the conveyor mechanism blows away the oil on the surface of the parts, thereby speeding up the drying of the parts, reducing production time, and thus reducing costs. Moreover, with both gates 11 closed, a sealed space is formed inside the housing, which can prevent the oil from being carried away by the strong wind and avoid polluting the air and environment of the production workshop.
[0024] like Figure 2 As shown, in this embodiment, the conveying mechanism 20 is a roller conveyor driven by a motor. The roller conveyor includes multiple rollers 201 spaced apart along the forward direction of the parts.
[0025] like Figure 1 and Figure 4 As shown, a waste gas recovery mechanism 40 is also provided on the housing 10. The waste gas recovery mechanism 40 includes two suction nozzles 41 and a blower 42. The two suction nozzles 41 are respectively located at the inlet 101 and outlet 102 of the housing 10. The suction nozzles 41 have a U-shaped structure and have multiple air inlets 411 on their inner surfaces. The blower 42 is located on one side of the housing 10 and is connected to the two suction nozzles 41 via a pipe 43. A filter 44 is connected to the outlet of the blower 42. The filter 44 has a filter bag for filtering out oil. The blower is electrically connected to a controller. When the inlet gate or outlet gate is opened, the waste gas, under the negative pressure generated by the blower 42, enters the filter 44 through the suction nozzles 41 and the air pipe 43. The oil in the waste gas is intercepted by the filter bag of the filter 44, while the clean air is directly discharged into the atmosphere.
[0026] During operation, the un-oiled parts 8 are first placed in the basket 9. A conveyor (not shown in the figure) then transports the basket 9 to the oil-immersion tank (not shown in the figure) for oil immersion. After immersion, the parts are conveyed to the top of the inlet 101 of the housing. When the part detection sensor detects a part, it sends a signal. Upon receiving the signal, the controller controls the horizontal cylinder 12 at the inlet 101 to move the corresponding gate 11, opening the inlet 101. Simultaneously, the blower starts. Thus, when the inlet or outlet gate is opened, the exhaust gas, under the negative pressure generated by the blower 42, enters the filter 44 through the suction nozzle 41 and air pipe 43. The oil in the exhaust gas is intercepted by the filter bag of the filter 44, while the clean air is directly discharged into the atmosphere, thus preventing pollution of the workshop environment. The conveyor places the basket 9 filled with parts 8 onto the conveying mechanism. Subsequently, the horizontal cylinder 12 at the inlet 101 drives the corresponding gate 11 to move, closing the inlet 411, creating a sealed space inside the housing. The conveyor mechanism moves the basket 9 towards the outlet 102. During this movement, the strong air blown by the air knife 30 located above the conveyor mechanism 20 blows away the oil on the surface of the parts, thereby accelerating the drying process. When the positioning sensor 22 detects the basket 9 and sends a signal, the controller receives the signal and controls the gate 11 at the outlet 102 to open. The conveyor then grabs the basket and transports it to the next process.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
