Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0027] The following reference Figures 1-4 As shown, further described in conjunction with specific embodiments, this embodiment provides a vacuum pump station, referring to Figure 1 、 Figure 2 As shown, the apparatus comprises a base frame 1, with an intermediate tank 2 mounted in the middle. A cover plate 27 is provided at the top of the intermediate tank 2, and an access panel 271 is hingedly mounted on the cover plate 27. Opening the access panel 271 allows access to the intermediate tank 2 for cleaning or maintenance. A vacuum pump assembly 3 is mounted on both sides of the base frame 1. The inlet pipe of the vacuum pump assembly 3 is connected to the vacuum tank, and the outlet pipe 31 of the vacuum pump assembly 3 is connected to the intermediate tank 2. During vacuum generation, the inlet pipe draws air into the vacuum tank, and oily waste gas is drawn from the vacuum tank into the intermediate tank 2 through the outlet pipe 31. A cooling water pipe 21 is mounted at the bottom of the intermediate tank 2, connecting to the cooling water inlet 32 ​​of the vacuum pump assembly 3. In addition to separating the oily waste gas from the oily waste gas, the water in the intermediate tank 2 also serves as cooling water to cool the vacuum pump assembly 3.

[0028] Reference Figure 3 、 Figure 4As shown, a discharge pipe 4 for discharging oily wastewater is provided on one side of the intermediate tank 2. This pipe 4 comprises a main pipe 41 vertically arranged outside the intermediate tank 2 and multiple branch pipes 42 distributed along the length of the main pipe 41. The intermediate tank 2 is provided with corresponding discharge ports 22, one-to-one with each branch pipe 42. The inner wall of the intermediate tank 2 is provided with multiple sealing plates 23 for sealing the discharge ports 22. By providing multiple discharge ports 22, the oily wastewater at the top of the intermediate tank 2 can be discharged through the discharge ports 22 at different heights when the liquid level in the intermediate tank 2 changes. Each of the multiple branch pipes 42 can direct the discharged oily wastewater into the main pipe 41. A drain pipe 28 is provided at the bottom of the intermediate tank 2. The bottom end of the main pipe 41 is connected to the drain pipe 28. A drain valve 281 is provided on the drain pipe 28, located between the intermediate tank 2 and the main pipe 41. When all the liquid in the intermediate tank 2 is discharged, the drain valve 281 is opened to allow the liquid to be discharged from the drain pipe 28; by connecting the bottom end of the main pipe 41 with the drain pipe 28, the discharged oil can also be discharged through the drain pipe 28, thereby reducing the pipeline settings required in the workshop.

[0029] Reference Figure 2 、 Figure 3 As shown, the intermediate tank 2 is equipped with a water inlet pipe 24, which extends from the top of the intermediate tank 2 to the bottom of the intermediate tank 2. The water inlet pipe 24 is equipped with a water inlet valve 241. The intermediate tank 2 is also equipped with an upper liquid level switch 25 and a lower liquid level switch 26 for opening and closing the water inlet valve 241. When the liquid level in the intermediate tank 2 is higher than the upper liquid level switch 25, the upper liquid level switch 25 closes the water inlet valve 241 to stop further water inflow. When the liquid level in the intermediate tank 2 is lower than the lower liquid level switch 26, the lower liquid level switch 26 opens the water inlet valve 241 to continue to allow fresh water to flow in.

[0030] Reference Figure 3 、 Figure 5 As shown, the intermediate tank 2 is also provided with a toggle mechanism 5 for collecting oil floating in the intermediate tank 2 to the discharge outlet 22. The toggle mechanism 5 includes a toggle portion 51 and a blocking portion 52. In vertical projection, the blocking portion 52 is fixedly mounted in the intermediate tank 2 and located to one side of the discharge outlet 22. The toggle portion 51 is rotatably mounted in the intermediate tank 2 along the circumference of the intermediate tank 2. The toggle portion 51 is provided with a toggle block 53 for toggling the closing plate 23 to open the discharge outlet 22. Activating the toggle mechanism 5 and moving the toggle portion 51 along the circumference of the intermediate tank 2 can toggle the oil suspended on the water surface. Since the fixed portion remains in a fixed position, when the toggle portion 51 rotates to a specified position, the oil is collected in the area enclosed between the toggle portion 51 and the fixed portion. At this time, the toggle block 53 opens the closing plate 23 at a specified height, allowing the oil to be discharged from the discharge outlet 22 at the corresponding height.

[0031] Reference Figure 5As shown, the dialing part 51 comprises a driving motor 511, a driving shaft 512 and a dialing rod 513, the driving motor 511 is fixedly arranged at the top of the middle tank 2, the driving shaft 512 is coaxially connected to the output shaft of the driving motor 511, one end of the dialing rod 513 is provided with a first sleeve 5131, the first sleeve 5131 is slidingly arranged on the driving shaft 512 along the length direction of the driving shaft 512, and the dialing block 53 is arranged at the end of the dialing rod 513 away from the first sleeve 5131; the blocking part 52 comprises a blocking rod 521, one end of the blocking rod 521 is provided with a second sleeve 522, and the second sleeve 522 is movably sleeved on the driving shaft 512; the dialing rod 513 and the blocking rod 521 are both hollow rods and can float on the water surface of the middle tank 2. By arranging the dialing rod 513 and the blocking rod 521 as hollow rods, and making the overall density of the dialing rod 513 and the blocking rod 521 less than the density of water, the dialing rod 513 and the blocking rod 521 can float on the water surface, so that when the driving motor 511 drives the driving shaft 512 to rotate, the dialing rod 513 rotates synchronously, the oil stains suspended on the water surface are stirred, and the second sleeve 522 can rotate relative to the driving shaft 512, so that the position of the blocking rod 521 remains unchanged during the rotation of the driving shaft 512. When the dialing rod 513 rotates to a specified position, the oil stains originally suspended on the entire water surface can be collected in the area between the blocking rod 521 and the dialing rod 513, so that the oil stains can be conveniently and quickly discharged, and a large amount of clean water will not be discharged during the discharging process.

[0032] Further, in the embodiment, limit strips 5121 are arranged on the opposite sides of the driving shaft 512 along the length direction of the driving shaft 512, limit grooves matched with the limit strips 5121 are formed in the first sleeve 5131, and the inner wall of the second sleeve 522 is in abutment with the limit strips 5121. Under the action of the limit strips 5121, the driving shaft 512 can drive the first sleeve 5131 to rotate synchronously, and the sliding of the first sleeve 5131 along the height direction of the driving shaft 512 is not affected. Since the second sleeve 522 is in clearance fit with the limit strips 5121, the second sleeve 522 can slide along the height direction of the driving shaft 512 and can rotate relative to the driving shaft 512, so that the position of the blocking rod 521 can remain unchanged during the rotation of the driving shaft 512. In order to further improve the stability of the blocking rod 521, an insertion slot for limiting the position of the end of the blocking rod 521 is formed in the inner wall of the middle tank 2 in the vertical direction, so as to ensure that the blocking rod 521 will not rotate under the driving of the driving shaft 512, and to ensure that the oil stains can be finally limited in the specified area for convenient discharge.

[0033] Reference Figure 4As shown, the bottom end of the closing piece 23 is hingedly provided on the intermediate tank 2, and a notch 231 is vertically provided on one side of the closing piece 23; an arcuate surface 531 is provided on the toggle block 53, and when the arcuate surface 531 is inserted into the notch 231, the closing piece 23 can be driven to rotate to open the discharge port 22, so that the oil can be discharged after it gathers in the area between the blocking rod 521 and the toggle rod 513.

[0034] Reference Figure 3 、 Figure 6 As shown, both sides of the bottom of the intermediate tank 2 are provided with intercepting members 6. The intercepting members 6 correspond to the water inlet end of the cooling water pipe 21 and can intercept impurities in the water. The intercepting member 6 includes an intercepting mesh frame 61 and a sponge block 62. The intercepting mesh frame 61 includes a bottom plate 611 and an arc-shaped side plate 612. The bottom surface of the sponge block 62 is in contact with the bottom plate 611, and one side surface of the sponge block 62 is in contact with the arc-shaped side plate 612, and the other side surface is in contact with the inner wall of the intermediate tank 2. Before entering the cooling water pipe 21, the water in the intermediate tank 2 will be filtered through the intercepting mesh frame 61 and the sponge block 62 in sequence, thereby greatly reducing the impurity content in the water that eventually enters the vacuum pump group 3 from the cooling water pipe 21, thereby protecting the vacuum pump group 3.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
