Description

Technical Field

[0001] This utility model relates to the field of food processing auxiliary equipment technology, and more specifically, to a vacuum pump station. Background Technology

[0002] A vacuum pump station is a complete system that uses multiple sets of vacuum pumps as vacuum-generating devices and vacuum tanks as vacuum storage devices. In the processing of hot pot base, a negative pressure suction system is required, and the vacuum pump station is one of the key pieces of equipment in this system, maintaining a vacuum state inside the vacuum tank to provide suction force.

[0003] During the process of evacuating the vacuum tank to a negative pressure state, the vacuum pump station inevitably draws oil fumes and particulate impurities into the intermediate tank. Therefore, it is necessary to drain the upper layer of oil sludge from the intermediate tank at regular intervals and add clean water in the same amount as the drained oil sludge. Currently, to ensure that the oil sludge is drained from the intermediate tank as thoroughly as possible, an excessive amount of clean water needs to be drained, resulting in a waste of water resources.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally 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 claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] The following is for reference Figures 1-4 As shown in the illustration, and further explained with reference to specific embodiments, this embodiment provides a vacuum pump station, referring to... Figure 1 , Figure 2 As shown, the system includes a base frame 1, with an intermediate tank 2 mounted in the middle of the base frame 1. A cover plate 27 is mounted on the top of the intermediate tank 2, and a maintenance plate 271 is hinged to the cover plate 27. Opening the maintenance plate 271 allows access to the intermediate tank 2 for cleaning or maintenance. Vacuum pump units 3 are mounted on both sides of the base frame 1. The inlet pipe of the vacuum pump unit 3 is connected to the vacuum tank, and the outlet pipe 31 of the vacuum pump unit 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 installed at the bottom of the intermediate tank 2, and the cooling water pipe 21 is connected to the cooling water inlet 32 ​​of the vacuum pump unit 3. The water in the intermediate tank 2, in addition to separating the oily waste gas, can also be used as cooling water to cool the vacuum pump unit 3.

[0028] Reference Figure 3 , Figure 4As shown, an intermediate tank 2 has a discharge pipe 4 on one side for discharging oily wastewater. The discharge pipe 4 includes 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 has corresponding outlets 22 on each branch pipe 42. Multiple sealing plates 23 are provided on the inner wall of the intermediate tank 2 to close the outlets 22. By providing multiple outlets 22, when the liquid level in the intermediate tank 2 changes, the uppermost layer of oil in the intermediate tank 2 can be discharged through outlets 22 at different heights. The multiple branch pipes 42 can all guide the discharged oil 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 and located between the intermediate tank 2 and the main pipe 41. When all the liquid in the intermediate tank 2 is drained, the drain valve 281 can be opened to allow the liquid to be drained from the drain pipe 28; by connecting the bottom end of the main pipe 41 to the drain pipe 28, the drained oil can also be drained through the drain pipe 28, thereby reducing the amount of piping 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. A water inlet valve 241 is installed on the water inlet pipe 24. The intermediate tank 2 is equipped with an upper level switch 25 and a lower 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 level switch 25, the upper level switch 25 closes the water inlet valve 241 to stop further water intake; when the liquid level in the intermediate tank 2 is lower than the lower level switch 26, the lower level switch 26 opens the water inlet valve 241 to continue supplying clean water.

[0030] Reference Figure 3 , Figure 5 As shown, the intermediate tank 2 is also equipped with a toggle mechanism 5 for collecting oil floating in the intermediate tank 2 to the discharge port 22. The toggle mechanism 5 includes a toggle part 51 and a blocking part 52. In vertical projection, the blocking part 52 is fixedly installed in the intermediate tank 2 and located on one side of the discharge port 22. The toggle part 51 is rotatably installed in the intermediate tank 2 along the circumference of the intermediate tank 2. The toggle part 51 is provided with a toggle block 53 for toggle the sealing plate 23 to open the discharge port 22. When the toggle mechanism 5 is activated and the toggle part 51 moves along the circumference of the intermediate tank 2, the oil floating on the water surface can be toggleed. Since the position of the fixed part remains unchanged, when the toggle part 51 rotates to the designated position, the oil collects in the area enclosed between the toggle part 51 and the fixed part. At this time, the toggle block 53 opens the sealing plate 23 at the designated height, and the oil can be discharged from the discharge port 22 at the corresponding height.

[0031] Reference Figure 5As shown, the actuating part 51 includes a drive motor 511, a drive shaft 512, and an actuating rod 513. The drive motor 511 is fixedly mounted on the top of the intermediate tank 2. The drive shaft 512 is coaxially connected to the output shaft of the drive motor 511. One end of the actuating rod 513 is provided with a first sleeve 5131, which is slidably mounted on the drive shaft 512 along its length. The actuating block 53 is located at the end of the actuating rod 513 away from the first sleeve 5131. The blocking part 52 includes a blocking rod 521, one end of which is provided with a second sleeve 522, which is movably mounted on the drive shaft 512. Both the actuating rod 513 and the blocking rod 521 are hollow rods and can float on the water surface of the intermediate tank 2. By configuring the actuating rod 513 and the blocking rod 521 as hollow rods, and ensuring that the overall density of the actuating rod 513 and the blocking rod 521 is less than the density of water, the actuating rod 513 and the blocking rod 521 can float on the water surface. Therefore, when the drive motor 511 is started and drives the drive shaft 512 to rotate, the actuating rod 513 rotates synchronously, actuating the oil sludge suspended on the water surface. The second sleeve 522 can rotate relative to the drive shaft 512. Therefore, the position of the blocking rod 521 remains unchanged during the rotation of the drive shaft 512. When the actuating rod 513 rotates to the designated position, it can gather the oil sludge that was originally suspended on the entire water surface into the area between the blocking rod 521 and the actuating rod 513, thereby facilitating the quick discharge of the oil sludge without causing a large amount of clean water to be discharged at the same time.

[0032] Furthermore, in this embodiment, limit strips 5121 are provided on both opposite sides of the drive shaft 512 along its own length direction. The first sleeve 5131 has a limit groove adapted to the limit strip 5121, and the inner wall of the second sleeve 522 is in contact with the limit strip 5121. Under the action of the limit strip 5121, the drive shaft 512 can drive the first sleeve 5131 to rotate synchronously without affecting the sliding of the first sleeve 5131 along the height direction of the drive shaft 512. Since the second sleeve 522 is clearance-fitted with the limit strip 5121, the second sleeve 522 can slide along the height direction of the drive shaft 512 and also rotate relative to the drive shaft 512. Therefore, the position of the blocking rod 521 can remain unchanged during the rotation of the drive shaft 512. To further improve the stability of the blocking rod 521, a slot is also provided on the inner wall of the intermediate tank 2 in the vertical direction to limit the position of the end of the blocking rod 521, so as to ensure that the blocking rod 521 will not rotate under the drive of the drive shaft 512, and to ensure that the oil stains can be limited to the designated area for easy discharge.

[0033] Reference Figure 4As shown, the bottom end of the sealing plate 23 is hinged to the intermediate tank 2, and a notch 231 is vertically opened on one side of the sealing plate 23; the actuating block 53 is provided with an arc-shaped surface 531, which can drive the sealing plate 23 to rotate to open the outlet 22 when the arc-shaped surface 531 is inserted into the notch 231, so that the oil can be discharged in a concentrated manner after the oil sludge accumulates in the area between the blocking rod 521 and the actuating rod 513.

[0034] Reference Figure 3 , Figure 6 As shown, the bottom of the intermediate tank 2 is equipped with intercepting components 6 on both sides. The intercepting components 6 correspond to the water inlet of the cooling water pipe 21 and can intercept impurities in the water. The intercepting components 6 include 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 attached to the bottom plate 611, one side of the sponge block 62 is attached to the arc-shaped side plate 612, and the other side is attached to the inner wall of the intermediate tank 2. Before entering the cooling water pipe 21, the water in the intermediate tank 2 will pass through the intercepting mesh frame 61 and the sponge block 62 for filtration, thereby significantly reducing the impurity content in the water that finally enters the vacuum pump unit 3 from the cooling water pipe 21, thus protecting the vacuum pump unit 3.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
