Description

Technical Field

[0001] The present application relates to the technical field of waste gas purification and treatment of rolling mills, and in particular to a finished product unit device for oil mist recovery. Background Art

[0002] The aluminum foil rolling process generates heat due to metal deformation. To remove this heat and provide proper lubrication, rolling oil is used as a lubricant and coolant. Rolling oil is continuously sprayed onto the rolls and the rolled material through nozzles. Due to the heat, some of the rolling oil is atomized, forming droplets of varying sizes that hang above the rolls, commonly known as rolling oil mist. In engineering, oil droplets larger than 5μm are typically referred to as liquid oil mist, while those smaller than 5μm are referred to as gaseous oil mist. Oil mist recovery systems currently address this issue, reducing oil mist gas emissions and repurifying and recycling the gas, thereby increasing rolling oil utilization. Finished product units play an irreplaceable role in oil mist recovery systems, allowing for further purification and storage of the light-fraction rolling oil after purification in the desorption tower.

[0003] Traditionally, a finished product unit consists of a finished product tank and a return tank. Oil from both tanks is pumped to the corresponding equipment. For example, patent CN221500982U utilizes a single gear pump to transfer oil from both tanks, reducing costs. However, this patent has drawbacks: multiple solenoid valves are required to control the on / off flow of the pipelines, complicating the control system. This excessive number of control points can easily lead to malfunctions. Therefore, a device for recovering oil mist from a finished product unit is proposed to address this technical issue.

DETAILED DESCRIPTION

[0020] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, the directions and positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.

[0022] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0023] One of the preferred embodiments of this application is as follows: Figures 1 to 6 As shown, an oil mist recovery finished product unit device includes a reflux tank 1, a finished product tank 2, multiple pipelines 3, a pump body 6, a sealing mechanism 4 and a driving device 5, wherein the pump body 6 is connected to the two tank bodies through multiple pipelines 3, the sealing mechanism 4 is arranged on the pipeline 3, and the output end of the driving device 5 is connected to the sealing mechanism 4.

[0024] Specifically, such as Figure 2 As shown, there are four pipelines 3, namely the first pipeline 301, the second pipeline 302, the third pipeline 303 and the fourth pipeline 304. The outlet of the reflux tank 1 is connected to the first pipeline 301, and the outlet of the finished product tank 2 is connected to the second pipeline 302. The input end of the pump body 6 is connected to the first pipeline 301 and the second pipeline 302, and the output end of the pump body 6 is connected to the third pipeline 303 and the fourth pipeline 304. The first pipeline 301 and the third pipeline 303 form a first flow channel 7, and the second pipeline 302 and the fourth pipeline 304 form a second flow channel 8.

[0025] It is understandable that when it is necessary to transport the liquid in the reflux tank 1 and the finished product tank 2, it is actually sufficient to control the opening and closing of the first flow channel 7 and the second flow channel 8. For example, when the driving device 5 performs the first action, the driving device 5 can drive the blocking mechanism 4 to close the first flow channel 7, at which time the second flow channel 8 is in a conducting state, that is, the oil in the finished product tank 2 is transported to the corresponding equipment; when the driving device 5 performs the second action, the driving device 5 can drive the blocking mechanism 4 to close the second flow channel 8, at which time the first flow channel 7 is in a conducting state, thereby transporting the oil in the reflux tank 1 to the corresponding equipment for reflux.

[0026] It can be seen that through different actions of the driving device 5, the blocking mechanism 4 can open and close different flow channels, that is, in the control system of the flow channel, the original combination control of multiple solenoid valves is now transformed into only requiring the separate control of the driving device 5, thereby simplifying the control logic of the entire system and reducing the possibility of failure.

[0027] As a further description of the above embodiment: Figure 2 and Figure 3 As shown, the sealing mechanism 4 includes four shells 401 and four sealing plates 402. The shells 401 are connected and installed in the corresponding pipelines 3. The sealing plates 402 are sealingly slidably arranged in the corresponding shells 401. The four sealing plates 402 are connected by brackets 9, and the four sealing plates 402 can be regarded as a whole. The bracket 9 is connected to the output end of the driving device 5, and the four shells 401 are distributed in a rectangular shape.

[0028] It can be understood that when the driving device 5 performs the first action, the sealing plate 402 will move in the first direction under the action of the driving device 5, and then the sealing plate 402 will block the pipe openings 11 of the first pipe 301 and the third pipe 303. At this time, the sealing plate 402 is completely misaligned with the pipe openings 11 of the second pipe 302 and the fourth pipe 304, that is, the pipe openings 11 of the second pipe 302 and the fourth pipe 304 are in an open state, and then the second flow channel 8 is in a conducting state, and the pump body 6 can transport the oil in the finished product tank 2 through the second flow channel 8. Similarly, when the driving device 5 performs the second action, the sealing plate 402 will move in the second direction under the action of the driving device 5, and then the sealing plate 402 is suitable for sealing the pipe openings 11 of the second pipe 302 and the fourth pipe 304. At this time, the sealing plate 402 is completely misaligned with the pipe openings 11 of the first pipe 301 and the third pipe 303, that is, the pipe openings 11 of the first pipe 301 and the third pipe 303 are in an open state, and then the first flow channel 7 is in a conducting state, and the pump body 6 can transport the oil in the reflux tank 1 through the first flow channel 7.

[0029] It should be noted that the first direction and the second direction are opposite to each other. For example, if the first direction is leftward, the second direction is rightward.

[0030] Further, such as Figure 4 and Figure 5 As shown, a through-opening 10 adapted to the pipe opening 11 of the pipeline 3 is provided on the sealing plate 402 , that is, the pipe opening 11 and the through-opening 10 are of the same size.

[0031] It can be understood that when the first flow channel 7 is in a closed state, the port 10 is suitable for cooperating with the second flow channel 8; when the second flow channel 8 is in a closed state, the port 10 is suitable for cooperating with the first flow channel 7. In other words, when the port 10 corresponds to the flow channel, the flow channel is in a conductive state; if the port 10 and the flow channel are completely misaligned, the flow channel is in a closed state. At the same time, the coordination between the port 10 and the nozzle 11 can also play such a role: the port 10 can overlap with the nozzle 11 of the pipeline 3 to limit the flow rate of the fluid. The greater the degree of overlap between the two, the greater the flow rate of the fluid; conversely, the smaller the degree of overlap between the two, the smaller the flow rate of the fluid; for example, when the port 10 and the nozzle 11 completely overlap, it represents the maximum flow rate.

[0032] It should be noted that in the prior art, if one wants to achieve the connection and disconnection between the first flow channel 7 and the second flow channel 8, four solenoid valves are generally required, that is, one is provided on each of the four pipelines 3. For example, assuming that the first flow channel 7 is conductive, the solenoid valves on the first pipeline 301 and the third pipeline 303 need to be opened, and the solenoid valves on the second pipeline 302 and the fourth pipeline 304 need to be closed; assuming that the second flow channel 8 is conductive, the solenoid valves on the second pipeline 302 and the fourth pipeline 304 need to be opened, and the solenoid valves on the first pipeline 301 and the third pipeline 303 need to be closed. First, there are many control points, and the control synchronization is not very good; second, it is not easy to control the flow rate; and third, if the solenoid valve fails, for example, when the first flow channel 7 is conductive, if the solenoid valve on the second pipeline 302 fails and cannot be closed, the oil in the finished product tank 2 will be pumped out for reflux, which will affect the operation of the system.

[0033] Specifically in this solution, the movement of the sealing plate 402 is used to realize the opening and closing of the two flow channels, because the sealing plate 402 can only realize the control of a single flow channel. That is, if the driving device 5 fails, no matter where the sealing plate 402 stays, the oil in the two tanks will not be mixed, thereby ensuring the safety and reliability of the system.

[0034] Furthermore, a monitoring module is provided at the output end of the pump body 6. The monitoring module is suitable for monitoring the pressure and flow of the pipeline 3. For example, the monitoring module can be a flow meter or a pressure gauge, thereby monitoring the flow and pressure of the liquid delivered by the pump body 6 in real time. When an abnormal situation is detected, the monitoring module can promptly issue an alarm and adjust the operating status of the pump body 6 through the control system to ensure the stability and safety of the entire delivery process.

[0035] In this embodiment, the driving device 5 has various structural forms, including but not limited to the following two:

[0036] Structure 1 (not shown): The driving device 5 includes a base 501 and a telescopic device, which is installed on the base 501 and the piston end is connected to the bracket 9; of course, the specific structure and working principle of the telescopic device are well known to those skilled in the art, so they will not be elaborated here; common telescopic devices include hydraulic cylinders, pneumatic cylinders and electric push rods.

[0037] It can be understood that the telescopic device drives the bracket 9 to push and pull the sealing plate 402 to move through the telescopic action; and the two actions of the driving device 5 above represent the extension and shortening actions of the telescopic device.

[0038] Structure 2 (such as Figure 3 and Figure 6 As shown): The driving device 5 includes a base 501, a motor 502 and a screw 503. The motor 502 is installed on the base 501 and the output end is connected to the screw 503. The screw 503 is threadedly matched with the bracket 9.

[0039] It is understandable that the motor 502 drives the screw 503 to rotate, the screw 503 acts on the bracket 9, and the bracket 9 can drive the sealing plate 402 to move; and the two actions of the above-mentioned driving device 5 represent the forward and reverse rotation of the motor 502.

[0040] It should be noted that if Structure 1 uses a pneumatic cylinder, it may generate significant thrust and vibration during initial startup, and its position may not be very precise when stopped. In contrast, when using Structure 2, we know that screw transmission has high precision and is particularly suitable for adjusting the overlap between the through port 10 and the nozzle 11, thereby regulating the fluid flow rate. Furthermore, the screw thread is self-locking, meaning that even if the motor 502 fails, the screw 503 can still ensure that the position of the bracket 9 does not shift. Both methods can meet practical needs, and those skilled in the art can choose according to actual circumstances.

[0041] The working principle of this utility model is:

[0042] like Figure 5 As shown in (a), this is the initial state, the four sealing plates 402 can block the pipe openings 11 of the four pipes 3, thereby making the first flow channel 7 and the second flow channel 8 both in a closed state. Figure 5 As shown in (b), the driving device 5 performs the first action, thereby causing the sealing plate 402 to move to the right, for example, so that the opening 10 on the sealing plate 402 overlaps with the pipe opening 11 on the second pipe 302 and the fourth pipe 304, thereby causing the pump body 6 to transport the oil in the finished product tank 2 to the corresponding equipment through the second flow channel 8. Figure 5As shown in (c), at this time, the driving device 5 performs the second action, thereby causing the sealing plate 402 to move to the left, for example, causing the opening 10 on the sealing plate 402 and the pipe openings 11 on the first pipe 301 and the third pipe 303 to overlap, thereby causing the pump body 6 to transport the oil in the reflux tank 1 to the corresponding equipment through the first flow channel 7.

[0043] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. These changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
