Description

Technical Field

[0001] The present application belongs to the technical field of oil removal air conditioning systems, and specifically relates to oil removal air conditioning systems. Background Art

[0002] With the development of intelligent factory processing workshops, a large number of process flows and assembly lines have begun to use automated equipment for production. While the production efficiency of the workshops has been improved, the workshop equipment, which originally required a large amount of lubricating oil for processing, has become more seriously affected by the introduction of automated mechanical processing. Figure 1 is a structural schematic diagram of an air conditioning system in the related art according to an exemplary embodiment. Figure 1 As shown, a return air inlet 21a of a return air branch duct is arranged above each of the added equipment 1 in the workshop, so as to promptly suck the oil mist air formed by each of the added equipment 1 into the return air branch duct. Each of the return air branch ducts is connected to the return air main duct 21. The return air main duct 21 aggregates the return air of each of the return air branch ducts to form a total return air, which is then uniformly sent to the heat exchange section 22 for heat exchange. The oil mist return air after heat exchange is re-sent into the workshop through the supply air duct 23. Once the oil mist concentration in the workshop is too high, it will not only affect the health of the workshop production staff, but also cause the return air oil mist content of the workshop air-conditioning system to be too high, causing corrosion damage to the inside of the air-conditioning equipment and affecting the service life of the air-conditioning. Summary of the invention

[0060] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other implementation methods obtained by ordinary technicians in the field without creative work belong to the scope of protection of the present application.

[0061] See also Figure 2 and Figure 3 , the oil removal air conditioning system includes:

[0062] The oil removal section 24 is formed between the return air main duct 21 and the heat exchange section 22 of the oil removal air conditioning system, and the oil removal section 24 includes:

[0063] The oil removal air duct 201 is used to transport the return air transported by the return air main air duct 21;

[0064] An oil removal component 202 is formed in the oil removal air duct 201 and is used to remove oil from the return air; and

[0065] The deoiled return air can be transported to the heat exchange section 22 through the deoiling air duct 201 for heat exchange.

[0066] Specifically, Figure 2 As shown, a return air inlet 21a of a return air branch duct is provided above each equipment 1 in the workshop to timely inhale the oil mist air formed by each equipment 1 into the return air branch duct. Each return air branch duct is connected to the return air main duct 21. The return air main duct 21 collects the return air of each return air branch duct to form a total return air, which is then uniformly sent to the heat exchange section 22 for heat exchange. An oil removal section 24 is provided between the return air main duct 21 and the heat exchange section 22 to remove oil from the return air, which can prevent the oil mist air from passing through the internal components of the air conditioning system such as the heat exchanger, causing corrosion to these internal components, and helps to ensure the service life of the air conditioning system.

[0067] At the same time, the return air after heat exchange is re-sent into the room through the air supply duct 23 of the air conditioning system, and the oil mist in the supply air is filtered out. On the one hand, it helps to ensure the air quality in the workshop and the health of the workshop production staff. On the other hand, there is no need to turn on the exhaust fan of the workshop to discharge the indoor air containing oil mist, which can solve the problem of cold / heat loss with exhaust air.

[0068] See also Figures 2 to 4 In one embodiment, the oil removal section 24 further comprises:

[0069] An exhaust air duct 203 is formed on the oil removal air duct 201 and is located at the air outlet side of the oil removal component 202;

[0070] The first air valve 204 is formed in the exhaust air duct 203, and the second air valve 205 is formed in the oil removal air duct 201. When the first air valve 204 is closed and the second air valve 205 is opened, the return air that has been deoiled by the oil removal component 202 is transported to the heat exchange section 22 through the oil removal air duct 201; and when the first air valve 204 is opened and the second air valve 205 is closed, the return air that has been deoiled by the oil removal component 202 is discharged through the exhaust air duct 203.

[0071] The above embodiment scheme is explained below through specific application. When cooling or heating, in order to avoid the loss of cold / heat in the workshop, the first air valve 204 can be controlled to be closed and the second air valve 205 can be opened. Under this control, the return air after oil removal is all sent to the heat exchange section 22, and after heat exchange, it is sent to the room through the air supply duct 23 for recirculation. In spring and autumn, when the outdoor temperature is suitable for human body, the doors and windows of the workshop can be opened to introduce outdoor air to control the indoor temperature. The air conditioning system can not turn on the cooling function, but operate in the ventilation mode, specifically: the first air valve 204 is controlled to be opened and the second air valve 205 is closed. Under this condition, the return air after oil removal is terminated at the closed second air valve 205 in the oil removal duct 201, and will not continue to enter the subsequent heat exchange section 22. Through the cut-off and guiding effect of the closed second air valve 205, the return air after oil removal is discharged from the exhaust duct 203 to the outside through the opened first air valve 204, which can solve the problem of indoor oil mist air being discharged to the outside to pollute the external air environment.

[0072] See also Figures 2 to 4 In one embodiment, the oil removal section 24 further comprises:

[0073] A fresh air duct 206 is formed on the exhaust air duct 203 and is located downstream of the exhaust air duct 203 in the air supply direction of the oil removal air duct 201;

[0074] The third air valve 207 is formed in the fresh air duct 206, and the fourth air valve 208 is formed in the oil removal air duct 201. When the first air valve 204 is closed and the second air valve 205, the third air valve 207 and the fourth air valve 208 are all opened, the return air deoiled by the oil removal component 202 is mixed with the fresh air introduced through the fresh air duct 206, and is transported to the heat exchange section 22 through the oil removal air duct 201; and when the second air valve 205 is closed and the first air valve 204, the third air valve 207 and the fourth air valve 208 are all opened, the return air deoiled by the oil removal component 202 is discharged through the exhaust air duct 203, and the fresh air introduced through the fresh air duct 206 is transported to the heat exchange section 22 through the oil removal air duct 201.

[0075] Specifically, for example, in summer, when the air conditioning system is turned on for cooling, in order to maintain the cooling capacity in the workshop and ensure the indoor air quality, the air conditioning system can be controlled as follows: when the first air valve 204 is controlled to be closed and the second air valve 205, the third air valve 207 and the fourth air valve 208 are all opened, the return air after oil removal is mixed with the fresh air introduced through the fresh air duct 206, and is transported to the heat exchange section 22 through the oil removal duct 201 for cooling treatment, and then is sent into the workshop through the supply air duct 23. In spring and autumn when the outdoor temperature is suitable for the human body, the air-conditioning system does not need to turn on the refrigeration function, and can introduce outdoor air through the fresh air duct 206 to control the indoor temperature. The air-conditioning system can be controlled as follows: the second air valve 205 is closed, and the first air valve 204, the third air valve 207 and the fourth air valve 208 are all opened. Due to the closure of the second air valve 205, on the one hand, the return air deoiled by the oil removal component 202 is completely discharged through the exhaust duct 203. On the other hand, the fresh air introduced through the fresh air duct 206 is transported to the heat exchange section 22 through the oil removal duct 201 (without heat exchange), and then sent into the workshop through the supply air duct 23 to improve the air quality in the workshop.

[0076] See also Figures 2 to 3 as well as Figures 5 to 8 In one embodiment, the degreasing assembly 202 comprises:

[0077] At least one linoleum board 2001;

[0078] At least one actuator 2002 is configured to fix or release the oil-absorbing felt plate 2001, and when fixing the oil-absorbing felt plate 2001, the oil-absorbing felt plate 2001 can be placed in the oil removal position to remove oil from the return air transported by the return air main duct 21, or the oil-absorbing felt plate 2001 can be placed in a waiting position to wait to move to the oil removal position.

[0079] Specifically, the actuator 2002 can perform two actions, one is to fix the oil-absorbing felt plate 2001, for example, it can be clamped and fixed, and the other is to move the oil-absorbing felt plate 2001, for example, to move the oil-absorbing felt plate 2001 to a waiting position or an oil removal position. Figure 3 As shown, the oil-absorbing felt plate 2001 in the waiting position is placed horizontally, and its oil-absorbing surface is parallel to the return air direction, and does not absorb oil from the return air; the oil-absorbing felt plate 2001 in the oil removal position is placed vertically, and its oil-absorbing surface is perpendicular to the return air direction, and absorbs oil from the return air.

[0080] In one embodiment, the oil-absorbing felt board 2001 comprises: an oil-absorbing non-woven fabric layer, an oil-absorbing fiber layer and a woven mesh layer.

[0081] Specifically, the oil-absorbing fiber layer can adopt three kinds of polypropylene melt-blown fibers with different diameters; the oil-absorbing non-woven fabric layer is provided with a number of evenly distributed through holes to improve the oil absorption rate. The oil-absorbing non-woven fabric has the characteristics of good oil absorption effect, high strength, low cost, high utilization rate and high reuse rate. At the same time, it is small in size, light in weight, and easy to transport and store.

[0082] See also Figure 5 and Figure 6 In one embodiment, the actuator 2002 includes:

[0083] The clamping claw portion 2002a is used to fix or release the oil-absorbing felt plate 2001;

[0084] The rotating portion 2002b is used to rotate the clamping jaw portion 2002a from the waiting position to the oil removal position, or to rotate the clamping jaw portion 2002a from the oil removal position to the waiting position.

[0085] Specifically, the clamping jaw 2002a can realize the two actions of clamping and releasing by the control of the controller. The oil-absorbing felt plate 2001 can be fixed by receiving the clamping control signal, and the oil-absorbing felt plate 2001 can be released by receiving the releasing control signal. The clamping jaw 2002a can realize the two rotation actions of rotating from the waiting position to the degreasing position or from the degreasing position to the waiting position by the control of the controller. For example, the oil-absorbing felt plate 2001 is clamped at the degreasing position by the clamping jaw, and the rotating portion 2002b is controlled by the controller to drive the clamping jaw 2002a to rotate, so that the oil-absorbing felt plate 2001 reaches the waiting position. In specific applications, a movable window can be formed on the degreasing air duct 201 directly above the waiting position, and the oil-absorbing felt plate 2001 can be replaced by opening the movable window.

[0086] See also Figure 3 , Figure 5 and Figure 6 In one embodiment, the oil removal section 24 further comprises:

[0087] A first movable buckle 209 is disposed on the oil removal air duct 201 directly below the oil removal position;

[0088] When the oil-absorbing felt plate 2001 in the oil-removing position is released by the corresponding actuator 2002 and the first movable buckle 209 is opened, the oil-absorbing felt plate 2001 in the oil-removing position falls out through the opening formed by the opened first movable buckle 209.

[0089] Specifically, when the first movable buckle 209 is opened, an opening is formed on the oil removal air duct 201 through which the oil-absorbing felt plate 2001 can fall down. After the oil-absorbing felt plate 2001 in the oil removal position is released by the corresponding actuator 2002, it can directly fall out through the opening. In a specific application, after the oil-absorbing felt plate 2001 in the oil removal position is released by the corresponding actuator 2002, the first movable buckle 209 can be closed again by delaying a certain time (for example, one second). After the oil-absorbing felt plate 2001 in the oil removal position is released by the corresponding actuator 2002, the controller can control the actuator 2002 to immediately reach the waiting position, waiting for the relevant personnel to operate and replace the new oil-absorbing felt plate 2001.

[0090] See also Figure 3 In one embodiment, the oil removal air conditioning system further comprises:

[0091] The cleaning tank 25 is disposed below the oil removal section 24 and is used to receive the oil-absorbing felt plate 2001 dropped by the opened first movable buckle 209 and to clean the dropped oil-absorbing felt plate 2001.

[0092] Specifically, the cleaning tank 25 is provided with a cleaning agent for removing oil stains on the oil-absorbing felt plate 2001 that has fallen into the cleaning tank 25. When the oil-absorbing felt plate 2001 in the oil removal position is released by the corresponding actuator 2002 and the first movable buckle 209 is opened, the oil-absorbing felt plate 2001 in the oil removal position falls out of the opening formed by the opened first movable buckle 209 and falls into the cleaning tank 25 for cleaning.

[0093] See also Figure 3 In one embodiment, the oil removal section 24 further comprises:

[0094] The positioning and blocking component 210 is used to position and block the oil-absorbing felt plate 2001 at the oil removal position.

[0095] Specifically, the positioning blocking component 210 may be a baffle, which can prevent the oil-absorbing felt plate 2001 from rotating out of position when the rotating portion 2002b rotates the clamping claw portion 2002a to rotate the oil-absorbing felt plate 2001 to the oil removal position.

[0096] In one embodiment, the degreasing assembly 202 includes:

[0097] Two sets of said oil-absorbing felt panels 2001, and

[0098] The two sets of the actuators 2002 are configured as follows: when one set of the actuators 2002 places the corresponding oil-absorbing felt plate 2001 in the oil removal position, the other set of the actuators 2002 places the corresponding oil-absorbing felt plate 2001 in the waiting position.

[0099] See also Figure 7 and Figure 8 The first set of clamping jaws 2002a1 corresponds to the first set of rotating parts 2002b1, and the second set of clamping jaws 2002a2 corresponds to the second set of rotating parts 2002b2.

[0100] Specifically, two sets of actuators 2002 and two corresponding sets of oil-absorbing felt plates 2001 are configured. When one set of oil-absorbing felt plates 2001 is placed in the oil removal position to filter the oil mist in the return air, the other set of oil-absorbing felt plates 2001 is placed in the waiting position as a spare part to wait for replacement.

[0101] See also Figure 3 In one embodiment, the oil removal section 24 further comprises:

[0102] The second movable buckle 211 is used to fix the front end of the oil-absorbing felt plate 2001 in the waiting position. When the second movable buckle 211 is opened, the oil-absorbing felt plate 2001 in the waiting position can be moved to the oil removal position by the actuator 2002.

[0103] Specifically, when the oil-absorbing felt plate 2001 is in the waiting position, Figure 3 In the horizontal placement shown, the actuator 2002 only fixes one end thereof, and the other end is not subjected to force, which makes it more difficult to fix the actuator 2002. By further providing a second movable buckle 211, when the oil-absorbing felt plate 2001 is in the waiting position, the corresponding actuator 2002 and the second movable buckle 211 cooperate with each other to stably fix the oil-absorbing felt plate 2001 in the waiting position for a long time. When the oil-absorbing felt plate 2001 in the waiting position needs to be used, the second movable buckle 211 can be controlled to open by the controller, and then the actuator 2002 corresponding to the oil-absorbing felt plate 2001 in the waiting position is controlled to act, so as to move the oil-absorbing felt plate 2001 in the waiting position to the oil removal position for oil removal.

[0104] See also Figure 3 and Fig. 9 In one embodiment, the oil removal air conditioning system further comprises:

[0105] The oil mist detection element 26 is used to detect the oil mist content of the return air after deoiling;

[0106] A missing detection element 27, used to detect whether the oil-absorbing felt plate 2001 is placed at the waiting position;

[0107] The controller 28 is used to:

[0108] Obtaining a detection value of the oil mist content in the return air after deoiling;

[0109] If the oil mist content detection value is greater than or equal to the preset threshold, determining whether the oil absorption felt plate 2001 is placed at the waiting position;

[0110] If the oil-absorbing felt plate 2001 is placed at the waiting position, the actuator 2002 corresponding to the oil-absorbing felt plate 2001 at the oil removal position is controlled to open to release the oil-absorbing felt plate 2001 at the oil removal position, and the first movable buckle 209 is controlled to open so that the oil-absorbing felt plate 2001 at the oil removal position falls out through the opened first movable buckle 209; then the second movable buckle 211 is controlled to open, and the actuator 2002 corresponding to the oil-absorbing felt plate 2001 at the waiting position is controlled to act to move the oil-absorbing felt plate 2001 at the waiting position to the oil removal position.

[0111] Through this embodiment scheme, when applied to the configuration of two sets of actuators 2002 and the corresponding two sets of oil-absorbing felt plates 2001, automatic detection control can be formed. For example, in the initial state, one of the actuators 2002 configures its corresponding oil-absorbing felt plate 2001 at the oil-absorbing position, and the other actuator 2002 configures its corresponding oil-absorbing felt plate 2001 at the waiting position. During the operation of the air-conditioning system, as the oil-absorbing felt plate 2001 at the oil-absorbing position continues to absorb oil, its oil removal capacity will gradually decrease. Therefore, the oil mist content in the return air after oil removal will gradually increase. The oil mist detection element 26 detects the return air after oil removal, and the controller 28 can continuously obtain the change of the detection value of the oil mist content in the return air after oil removal, and compare it with the preset threshold value. The preset threshold value can be a value at which the oil removal capacity is about to be saturated or a saturated value of the oil removal capacity. When the oil mist content detection value is greater than the preset threshold value, it indicates that the oil removal capacity of the oil absorption felt plate 2001 at the oil absorption position is close to saturation or has been saturated and needs to be replaced. In this case, it is determined whether there is an oil absorption felt plate 2001 placed at the waiting position. According to the initial state set above, the controller 28 detects that there is an oil absorption felt plate 2001 placed at the waiting position through the missing detection element 27, and then further controls the actuator 2002 corresponding to the oil absorption felt plate 2001 at the oil removal position to open, so as to release the oil absorption felt plate 2001 at the oil removal position with saturated oil removal capacity, and controls the first active buckle 209 to open, so that the oil absorption felt plate 2001 at the oil removal position falls out through the opening buckle formed by the opened first active buckle; then controls the second active buckle 211 to open, and controls the actuator 2002 corresponding to the oil absorption felt plate 2001 at the waiting position to act, so as to move the oil absorption felt plate 2001 at the waiting position to the oil removal position.

[0112] In one embodiment, the controller 28 is further configured to:

[0113] If the oil-absorbing felt sheet 2001 is not placed at the waiting position, an alarm is issued.

[0114] Specifically, following the above-mentioned specific application instructions, after the oil-absorbing felt board 2001 that was previously in the oil removal position is released and the oil-absorbing felt board 2001 that was in the waiting position is moved to the oil removal position for oil removal, there is no oil-absorbing felt board 2001 at the waiting position, and it is necessary to wait for relevant personnel to replenish and place it.
