Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0023] Please also read Figure 1 and Figure 2The air compressor condensate collection device provided by the utility model is now described. The air compressor condensate collection device comprises a cylinder 10 and a driving member 20; a first partition 11 is vertically arranged in the cylinder 10, and the first partition 11 divides the inside of the cylinder 10 into a separation chamber 30 and a water outlet chamber 40, a connection port 111 is arranged at the bottom of the first partition 11, and a baffle 112 is slidably connected to the first partition 11, and the baffle 112 has an open state of sliding to the top of the connection port 111, and also has a closed state of sliding to block the connection port 111; the output end of the driving member 20 is connected to the baffle 112, and is used to drive the baffle 112 to switch between a closed state and an open state; a liquid inlet 12 connected to the separation chamber 30 is provided on the cylinder 10, and the liquid inlet 12 is used to connect the condensate discharge port of the air compressor, and a drain port 13 connected to the water outlet chamber 40 is also provided on the cylinder 10.

[0024] It should be noted that a switch that can be opened and closed can be provided on the liquid inlet 12. By opening and closing the switch, the liquid inlet 12 is discharged into the separation chamber 30 at intervals. When the oil-containing condensed water is discharged into the separation chamber 30, the baffle 112 is in a closed state. After a certain amount of oil-containing condensed water is discharged into the separation chamber 30 and left to stand for a certain period of time, the baffle 112 is switched to an open state, which can increase the standing time of the oil-containing condensed water entering the separation chamber 30 and improve the separation degree of the oil-containing condensed water; there is always a certain amount of condensed water in the separation chamber 30 and the water outlet chamber 40, and the condensed water liquid level is located at the lower end of the drain port 13, so as to prevent the oil-containing condensed water entering the separation chamber 30 from entering the water outlet chamber 40 from the connecting port 111 after the oil-water separation, thereby ensuring that the oil and condensed water are fully separated and preventing the oil in the condensed water from polluting the environment; the oil generated after the oil-water separation of the oil-containing condensed water is regularly cleaned to prevent oil accumulation.

[0025] The beneficial effects of the air compressor condensate collection device provided by the utility model are as follows: compared with the prior art, the utility model adopts a separation chamber 30 and a water outlet chamber 40, which can collect the condensate generated in the air compressor and prevent the oil-containing condensate from being directly discharged to the outside and polluting the external environment; the baffle 112 that can switch the working state enables the connection port 111 to be opened and closed, and the baffle 112 can block the oil-containing condensate from entering the water outlet chamber 40 when in the closed state, and discharge the condensate after oil-water separation from the water outlet chamber 40 when in the open state, so that the oil-containing condensate generated in the air compressor is separated from the oil-water, and the oil-containing condensate discharged to the outside is prevented from polluting the external environment, which is beneficial to energy conservation and environmental protection and realizes resource maximization.

[0026] In one possible implementation, see Figure 2A second partition 14 is horizontally arranged in the cylinder 10, the lower end of the first partition 11 is connected to the second partition 14, and the space inside the cylinder 10 below the second partition 14 forms a cooling chamber 50, the cooling chamber 50 is connected to the drain port 13, and a first water outlet 15 connected to the cooling chamber 50 is provided on the cylinder 10.

[0027] It should be noted that the second partition 14 divides the cylinder 10 into two parts, the upper and lower parts. The part between the second partition 14 and the inner top wall of the cylinder 10 forms a separation chamber 30 and a water outlet chamber 40. The first partition 11 is connected to the second partition 14 and has a connecting port 111 therebetween. When the connecting port 111 is in an open state, the separation chamber 30 and the water outlet chamber 40 are interconnected and have the same condensed water level. The condensed water after oil-water separation will increase the condensed water level in the connected separation chamber 30 and the water outlet chamber 40, and the excess condensed water will be discharged from the drain port 13. The process temperature of the compressed gas generated by the air compressor continues to rise, and high-temperature condensed water will be generated in the compressed air. The cooling chamber 50 can cool the high-temperature condensed water into low-temperature condensed water. The treated low-temperature condensed water is more convenient for collection and recycling of water resources.

[0028] In one possible implementation, see Figure 1 and Figure 2 The air compressor condensate collection device also includes a water storage tank 60, which is lower than the cylinder 10 and connected to the first water outlet 15. A water pump 61 is arranged in the water storage tank 60. A cooling pipe 51 is vertically arranged in the cooling chamber 50. The lower end of the cooling pipe 51 passes through the cylinder 10 and is connected to the water pump 61. A drainage component 52 is arranged at the upper end of the cooling pipe 51. A cooling channel 53 is arranged around the cooling pipe 51 in the cooling chamber 50. One end of the cooling channel 53 is connected to the drainage port 13, and the other end is connected to the first water outlet 15.

[0029] It should be noted that the water tank 60 is used to collect low-temperature condensed water after being processed by the cooling chamber 50. The water tank 60 accumulates the low-temperature condensed water to avoid direct discharge of the low-temperature condensed water to the outdoors, which is beneficial to saving water resources and meeting environmental protection requirements. The cooling pipe 51 can pass the low-temperature condensed water in the water tank 60 into the cooling chamber 50. The low-temperature condensed water in the water tank 60 is mixed with the high-temperature condensed water entering the cooling chamber 50 from the drain port 13 after oil-water separation, thereby reducing the temperature of the high-temperature condensed water. In addition, the outer wall temperature of the vertically arranged cooling pipe 51 filled with low-temperature condensed water is relatively low, which can reduce the temperature of the high-temperature condensed water in contact with the outer wall of the cooling pipe 51. The cooling channel 53 is spirally wrapped around the cooling pipe 51, and the cooling channel 53 is located at a lower position on the side close to the cooling pipe 51, which is beneficial for the condensed water in the cooling chamber 50 to be close to the cooling pipe 51, so that the cooling effect is more effective. The cooling channel 53 cooperates with the cooling pipe 51 to cool the high-temperature condensed water, which is convenient for subsequent resource recycling and is beneficial to energy saving and environmental protection.

[0030] In one possible implementation, the drainage component 52 includes a nozzle 521 and a one-way drainage valve 522; wherein, the one-way drainage valve 522 is arranged in the cooling pipe 51, and the nozzle 521 is connected to the top of the cooling pipe 51. When the water pump 61 is turned on, the one-way drainage valve 522 is opened under the action of water pressure, and when the water pump 61 is turned off, the one-way drainage valve 522 is closed accordingly.

[0031] It should be noted that when the one-way drain valve 522 is in a closed state, the one-way drain valve 522 can seal the cooling pipe 51, and the external high-temperature condensed water cannot enter through the nozzle 521 and flow back into the cooling pipe 51, thereby preventing the high-temperature condensed water from entering the cooling pipe 51 and causing the temperature of the cooling pipe 51 to rise; when the cooling pipe 51 transports low-temperature condensed water into the cooling chamber 50, the flowing low-temperature condensed water impacts the one-way drain valve 522 under the power provided by the water pump 61, so that the one-way drain valve 522 automatically switches to an open state; when the one-way drain valve 522 is in an open state, a channel for the discharge of low-temperature condensed water is generated in the cooling pipe 51, and the low-temperature condensed water flows through the channel and is sprayed out from the nozzle 521. The one-way drain valve 522 can automatically open when the high-temperature condensed water needs to be cooled, and can effectively cool the high-temperature condensed water, while reducing drive, saving resources, and being beneficial to energy conservation and environmental protection, thereby maximizing resources.

[0032] In a possible implementation, the cooling channel 53 is a spiral groove provided on the wall of the cooling chamber 50; and the nozzle 521 is used for spraying toward the spiral groove.

[0033] It should be noted that the cooling channel 53 is a water trough spirally arranged in the cooling chamber 50, which can receive the low-temperature condensed water sprayed from the nozzle 521, so that the high-temperature condensed water in the cooling channel 53 is mixed with the low-temperature condensed water sprayed from the nozzle 521, thereby reducing the temperature of the high-temperature condensed water, which is beneficial to fully cooling the high-temperature condensed water, facilitating the recycling of water resources, and benefiting energy conservation and environmental protection.

[0034] In a possible implementation, the cylinder 10 is provided with an oil outlet 16 communicating with the separation chamber 30 . The oil outlet 16 and the drain port 13 are both higher than the connecting port 111 , and the oil outlet 16 is higher than the drain port 13 .

[0035] It should be noted that a switch that can be opened and closed can be set at the oil outlet 16, and the oil outlet 16 is opened regularly to discharge the oil to avoid excessive accumulation of oil in the separation chamber 30; the height of the drain port 13 is lower than the height of the oil outlet 16. Since the oil molecules will be placed above the liquid level of the water molecules, when the baffle 112 is in the open state to connect the separation chamber 30 and the water outlet chamber 40, the condensed water below the oil in the separation chamber 30 and the water outlet chamber 40 will be discharged from the lower height drain port 13 first, and the oil accumulated in the separation chamber 30 will be discharged from the oil outlet 16. The height of the connecting port 111 is lower than the first water outlet 15 and the oil outlet 16, which can ensure that when the baffle 112 is in the open state, the first partition plate 11 can effectively block the oil from moving to the water outlet chamber 40, thereby improving the effectiveness of condensed water oil-water separation, avoiding oil molecules in the oil-containing condensed water from blocking the pipeline, and purifying the condensed water, which is conducive to the subsequent reuse of water resources.

[0036] In one possible implementation, the driving member 20 includes a rotating power member 21 and a transmission assembly 22. The rotating power member 21 is arranged on the outer top wall of the cylinder 10. The power input end of the transmission assembly 22 is connected to the rotating power member 21, and the power output end is connected to the baffle 112. The transmission assembly 22 is used to convert the rotational motion of the driving member 20 into the linear motion of the baffle 112.

[0037] It should be noted that the driving member 20 provided on the cylinder 10 controls the baffle 112 to switch the working state through the transmission assembly 22. The rotating power member 21 can be a motor, which converts the rotational power generated by itself into the linear motion of the baffle 112 through the transmission assembly 22, so that the oil-water separation of the oil-containing condensed water can be carried out smoothly, avoiding the blockage of the equipment pipeline by the oil-containing condensed water and facilitating the subsequent recycling of water resources.

[0038] In some embodiments, the transmission assembly includes a gear 221 and a rack 222 . The gear 221 is sleeved on the output end of the rotating power member 21 . The rack 222 is vertically fixed on the baffle 112 . The top end of the rack 222 extends out of the cylinder 10 and meshes with the gear 221 .

[0039] It should be noted that the rotating power part 21 controls the gear 221 to rotate and drive the rack 222 to move in the vertical direction. The length of the rack 222 is less than the distance from the connecting port 111 to the drain outlet 13, so that the highest position of the upward movement of one end of the baffle 112 in the separation chamber 30 when in the closed state is lower than the lower end of the drain outlet 13, that is, the end of the baffle 112 at the connecting port 111 is still below the condensed water level when it is in the highest position, which prevents the baffle 112 from extending into the oil when in the open state and bringing the oil into the water outlet chamber 40 when in the switching state, which is beneficial to improving the separation degree of oil-containing condensed water and improving the safety of pipeline use.

[0040] In a possible implementation, a liquid level meter 62 is provided on the inner wall of the water tank 60 , a second water outlet 63 is opened in the water tank 60 , and a switch valve 631 is provided on the second water outlet 63 .

[0041] It should be noted that the liquid level gauge 62 can display the liquid level value in the water tank 60 and there is a maximum capacity threshold and a minimum capacity threshold. The liquid level gauge 62 has a controller, which receives the liquid level value detected by the liquid level gauge 62 and controls the switch of the switch valve 631 based on the value. The second water outlet 63 has an open state and a closed state. When the liquid level is between the maximum capacity threshold and the minimum capacity threshold, the switch valve 631 is closed and the second water outlet 63 is in a closed state. When the condensed water level in the water tank 60 reaches the maximum capacity threshold, the switch valve 631 is opened and the second water outlet 63 is switched to an open state. When the condensed water level in the water tank 60 reaches the minimum capacity threshold, the second water outlet 63 is switched to a closed state. The condensed water generated by the air compressor can be collected within a reasonable range, which meets environmental protection requirements.

[0042] In a possible implementation, the switch valve 631 is connected to a cooling liquid pipe 64, and the cooling liquid pipe 64 is used to connect to a water cooling system of the air compressor.

[0043] It should be noted that the temperature of the compressed gas generated by the air compressor is too high, and a water cooling system is required to cool the compressed gas. The condensed water in the water storage tank 60 can also be used as supplementary water for the coolant in the water cooling system of the air compressor. After the switch valve 631 is opened, the second water outlet 63 is in an open state, and the low-temperature condensed water is passed into the water cooling system of the air compressor through the cold liquid pipe 64, so that the condensed water generated in the air compressor is collected and re-enters the water cooling system of the air compressor for recycling, saving water resources and meeting environmental protection requirements.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
