Description

Technical Field

[0001] The utility model relates to the technical field of storage tank flushing, and more specifically, the utility model relates to a vacuum flushing system for a storage tank. Background Art

[0002] As an important building container, the storage tank plays a key role in sewage treatment and rainwater collection. It can effectively store sewage or rainwater and ensure the stable operation of related systems. However, during the collection and storage process, due to factors such as water flow carrying, dirt and sediment often accumulate at the bottom. When the stored water is drained, in order to maintain the good storage performance and water quality environment of the storage tank, it is extremely necessary to clean its interior. This not only helps prevent damage to the storage tank structure caused by impurity accumulation but also ensures the quality of subsequent sewage or rainwater collection and storage, guaranteeing the efficient and long-term operation of the entire treatment and collection system.

[0003] In the existing vacuum flushing system for a storage tank, the process of replacing the filter screen each time is complex and time-consuming. Maintenance personnel may need to spend a lot of time disassembling the surrounding complex components to access the filter screen for replacement. When the filter screen is blocked, the resistance of water flow through the filter screen increases, reducing the amount of water entering the vacuum system, thereby reducing the flushing effect of the flushing system. This may cause the dirt at the bottom and side walls of the storage tank not to be thoroughly flushed clean, affecting the cleanliness of the storage tank. Therefore, improvement and optimization are needed. Summary of the Utility Model

Specific implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 to 7As shown in the figure, the utility model provides a vacuum flushing system for a storage tank, including a storage tank 1. An extension plate 2 is fixedly installed on the left side of the storage tank 1. A power mechanism is fixedly installed on the top of the extension plate 2. The outer surface of the flushing mechanism is fixedly connected with a second connecting pipe 9, and the second connecting pipe 9 extends into the storage tank 1. An annular sleeve 11 is movably sleeved on the outer surface of the second connecting pipe 9. A limiting ring 12 located inside the annular sleeve 11 is fixedly sleeved on the outer surface of the second connecting pipe 9. An L-shaped pushing block 13 located on the right side of the limiting ring 12 is fixedly sleeved on the inner wall of the annular sleeve 11. A spring 14 is connected between the limiting ring 12 and the L-shaped pushing block 13. A circular groove 15 located on the right side of the L-shaped pushing block 13 is formed on the outer surface of the second connecting pipe 9, and the circular grooves 15 are evenly spaced in a circumferential array at equal intervals. A limiting clamping ball 16 is placed inside the circular groove 15. A third connecting pipe 18 is movably installed inside the second connecting pipe 9. An annular trapezoidal sleeve block 19 is fixedly sleeved on the outer surface of the third connecting pipe 18, and the annular trapezoidal sleeve block 19 is located inside the circular groove 15 and the limiting clamping ball 16. A flexible film 17 is fixedly installed inside the circular groove 15, and the flexible film 17 is located between the limiting clamping ball 16 and the annular trapezoidal sleeve block 19. Clamping blocks 20 are fixedly installed on the upper and lower inner walls of the third connecting pipe 18. A filter screen 21 is placed on the left side of the clamping block 20 inside the third connecting pipe 18.

[0025] When the filter screen 21 is easily blocked after long-term water flow, the staff makes the annular sleeve 11 slide to the right on the surface of the second connecting pipe 9 by external force. At this time, the L-shaped pushing block 13 will squeeze the spring 14, and at the same time, the extrusion force on the top of the limiting clamping ball 16 will disappear. As a result, the limiting clamping ball 16 originally stuck inside the annular trapezoidal sleeve block 19 will return to its original position due to the elastic recovery of the flexible film 17 fixedly installed inside the circular groove 15. Thus, the third connecting pipe 18 can be smoothly pulled out to remove the filter screen 21. During the water flow, the filter screen 21 will be firmly attached to the clamping block 20 by the flowing pressure and will not be washed away. When installation is required, the filter screen 21 is placed on the left side of the clamping block 20, aligned with the second connecting pipe 9 and inserted into the interior. Then, when the external force on the annular sleeve 11 disappears, the L-shaped pushing block 13 is pushed by the elastic recovery of the spring 14 to squeeze the limiting clamping ball 16 into the inside of the annular trapezoidal sleeve block 19, realizing the replacement of the filter screen 21.

[0026] The elastic recovery effect of the flexible film 17 fixedly installed on the inner side of the circular groove 15 allows the limit ring 12 to return to its original position, so that the third connecting pipe 18 can be smoothly pulled out to remove the filter screen 21. Since the filter screen 21 will be firmly attached to the block 20 by the pressure of the flow during the flow of water and will not be washed away, when it needs to be installed, the filter screen 21 is placed in the left side of the block 20, aligned with the second connecting pipe 9 and placed inward, and then the external force of the annular sleeve 11 disappears. Due to the elastic recovery effect of the spring 14, the L-shaped pushing block 13 is pushed to squeeze the limit card ball 16 and snap it into the inner side of the annular trapezoidal sleeve block 19 to realize the replacement of the filter screen 21. Compared with the traditional device, this device greatly reduces the time and labor cost required for system maintenance, can quickly complete the replacement of the filter screen 21, and restore the system to operation as soon as possible, improve the efficiency and quality of flushing, ensure the smooth progress of the entire flushing process, and enhance the adaptability and flexibility of the system.

[0027] Among them, the power mechanism includes a first base 3 fixedly installed on the top of the extension plate 2, a vacuum pump 4 fixedly installed on the top of the first base 3, a second base 5 fixedly installed in front of the first base 3 on the top of the extension plate 2, a vacuum tank 6 fixedly installed on the top of the second base 5, a water tank 7 fixedly installed on the top of the vacuum tank 6, the vacuum pump 4 and the vacuum tank 6 are fixedly connected by a connecting pipe 10, a second connecting pipe 9 is fixedly connected to the outer surface of the vacuum tank 6, and a flushing mechanism is fixedly sleeved on the right side of the third connecting pipe 18.

[0028] When cleaning is required, the vacuum pump 4 is started so that the vacuum pump 4 gradually extracts the air in the vacuum tank 6 through the connecting pipe 10, so that a certain degree of vacuum environment is formed in the vacuum tank 6. When flushing is required, the water tank 7 is fixedly connected to the second connecting pipe 9 through the first connecting pipe 8, and the second connecting pipe 9 is fixedly connected to the vacuum tank 6. Therefore, under the action of the vacuum pressure difference, water will pass through the second connecting pipe 9 and then through the third connecting pipe 18 at a high speed through the flushing mechanism into the regulating reservoir, so as to flush the pool bottom and pool wall.

[0029] By moving the vacuum pump 4, the vacuum pump 4 gradually draws out the air in the vacuum tank 6 through the connecting pipe 10, so that a certain degree of vacuum environment is formed in the vacuum tank 6. When flushing is required, the water tank 7 is fixedly connected to the second connecting pipe 9 through the first connecting pipe 8, and the second connecting pipe 9 is fixedly connected to the vacuum tank 6. Therefore, under the action of the vacuum pressure difference, water will pass through the second connecting pipe 9 and then through the third connecting pipe 18 at a high speed through the flushing mechanism and into the regulating reservoir. Compared with traditional devices, this device provides sufficient energy, so that the vacuum tank 6 can quickly generate a vacuum environment, thereby improving the intelligence and safety of the entire vacuum flushing system.

[0030] Among them, the flushing mechanism includes that the right side of the third connecting pipe 18 is fixedly sleeved with an O-shaped flow pipe 23, and the third connecting pipe 18 extends into the O-shaped flow pipe 23. The inner outer surface of the O-shaped flow pipe 23 is fixedly connected with a conversion pipe 24. The inner wall of the storage tank 1 is fixedly installed with a support block 22, and the support block 22 movably sleeved the O-shaped flow pipe 23. The bottom side of the conversion pipe 24 is fixedly installed with a water outlet 25.

[0031] By fixedly connecting the conversion pipe 24 to the inner outer surface of the O-shaped flow pipe 23, the high-speed water flow can be effectively used to clean the storage tank through the water outlet 25.

[0032] Among them, support blocks 22 are fixedly installed on both sides of the inner wall of the storage tank 1, and the support blocks 22 movably sleeve the O-shaped flow pipe 23.

[0033] By fixedly installing the support blocks 22 on both sides of the inner wall of the storage tank 1 and the support blocks 22 movably sleeving the O-shaped flow pipe 23, the reaction force during the flushing of the storage tank by the high-speed water flow can be effectively borne, increasing the safety.

[0034] Among them, the inner outer surface of the O-shaped flow pipe 23 is fixedly connected with a conversion pipe 24, and the conversion pipe 24 is presented around the inner outer surface of the O-shaped flow pipe 23. The bottom side of the conversion pipe 24 is fixedly installed with a water outlet 25.

[0035] By presenting the conversion pipe 24 around the inner outer surface of the O-shaped flow pipe 23, the storage tank can be effectively flushed through the water outlet 25 on all sides.

[0036] Among them, the bottom side of the conversion pipe 24 is fixedly installed with a water outlet 25, and the water outlets 25 are arranged in a circumferential array.

[0037] By arranging the water outlets 25 in a circumferential array, the dead corners during flushing can be reduced, increasing the flushing efficiency.

[0038] Among them, a third base 26 is fixedly installed at the bottom of the storage tank 1, and the third base 26 is presented around the bottom of the storage tank 1. The right side of the storage tank 1 is fixedly connected with a drain pipe 27.

[0039] By presenting the third base 26 around the bottom of the storage tank 1, the stability of the whole device during operation can be effectively improved, and the drain pipe 27 can be opened during operation to facilitate the discharge of sewage during flushing.

[0040] The working principle and usage process of the present utility model:

[0041] When the filter screen 21 is prone to blockage after long-term water flow, the staff externally forces the annular sleeve 11 to slide to the right on the surface of the second connecting pipe 9. At this time, the L-shaped pushing block 13 will squeeze the spring 14, and at the same time, the extrusion force at the top of the limit clamping ball 16 will disappear. As a result, the limit clamping ball 16 that was originally stuck inside the annular trapezoidal sleeve block 19 will, due to the elastic recovery of the flexible film 17 fixedly installed inside the circular groove 15, cause the limit ring 12 to return to its original position. Thus, the third connecting pipe 18 can be smoothly pulled outwards to remove the filter screen 21. Due to the block 20, during the water flow, the filter screen 21 will be firmly attached to the block 20 by the flowing pressure and will not be washed away. When installation is required, the filter screen 21 is placed on the left side of the block 20 and aligned with the second connecting pipe 9 and inserted into it. Then, when the external force on the annular sleeve 11 disappears, due to the elastic recovery of the spring 14, the L-shaped pushing block 13 is pushed to squeeze the limit clamping ball 16 into the inside of the annular trapezoidal sleeve block 19, realizing the replacement of the filter screen 21.

[0042] When cleaning is required, start the vacuum pump 4 so that the vacuum pump 4 gradually evacuates the air in the vacuum tank 6 through the connecting pipe 10, creating a certain degree of vacuum environment in the vacuum tank 6. When flushing is required, the water tank 7 is fixedly connected to the second connecting pipe 9 through the first connecting pipe 8, and the second connecting pipe 9 is fixedly connected to the vacuum tank 6. Thus, under the action of the vacuum pressure difference, water will pass through the second connecting pipe 9 and then through the third connecting pipe 18 and rush into the storage pond at high speed through the flushing mechanism to flush the bottom and walls of the pond.
