Description

Technical Field

[0001] The utility model relates to the technical field of vacuum flushing, in particular to an integrated vacuum flushing device. Background Art

[0002] The vacuum flushing device is an important part of the sponge city facilities. Its appearance makes it unnecessary to invest a lot of manpower in the dredging of the pool, eliminates safety hazards, realizes regular and automatic operation, avoids the solidification of sediments, and ensures the effective volume of the pool. It takes a short time, consumes less energy, and has little impact on the outside world: at the same time, there is no running equipment inside the pool, and it is maintenance-free for life. However, all this is based on creating a relatively vacuum environment in the water storage chamber. The sealing of the water storage chamber will affect the flushing effect of the overall system. At present, the water storage chamber is mostly made of reinforced concrete, which belongs to the category of civil structure construction and belongs to a different installation department from the equipment. Since the conventional depth of the water storage chamber is 8-10m, during the actual on-site pouring process, due to the on-site formwork and the solidification characteristics of the concrete itself. Some water storage chamber walls have leaks, which affect the sealing. Secondary leak detection and repair are required, and the installation time is long. At the same time, some leaks are in a small and closed space and cannot be effectively repaired. In the later use process, the vacuum pump of the above leak point is frequently started to maintain pressure, which increases the daily energy consumption. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a prior art structure diagram of an embodiment of the utility model;

[0013] Figure 2 It is a structural diagram of an embodiment of the utility model.

[0014] The figure includes: a vacuum diaphragm valve 1, a vacuum pump 2, a valve control box 3, an air compressor 4, a water storage chamber 5, a top plate 61, and a side plate 62. DETAILED DESCRIPTION

[0015] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings.

[0016] like Figure 2 As shown, an integrated vacuum flushing device of an embodiment of the utility model includes a vacuum diaphragm valve 1, a vacuum pump 2, a valve control box 3, an air compressor 4, a water storage chamber 5 and a sealing assembly; one end of the vacuum diaphragm valve 1 is fixed to the top surface of the water storage chamber 5, and the other end is connected to the valve control box 3; the vacuum pump 2 is connected to the valve control box 3 through a pipeline; the air compressor 4 is connected to the valve control box 3 through a pipeline; the sealing assembly is arranged on the inner wall of the water storage chamber 5.

[0017] In the integrated vacuum flushing device of the above structure, a sealing component is arranged on the inner wall of the water storage chamber 5. The water storage chamber 5 is a concrete structure. The sealing component keeps the inner wall and the top of the water storage chamber 5 sealed, so that the water storage chamber 5 is in a better sealed vacuum state, thereby ensuring that the water in the water storage chamber 5 will not leak, and ensuring the flushing effect and operation stability of the flushing device; at the same time, the sealing component is modularized into a top plate 61 and a plurality of side plates 62, so that transportation, installation and maintenance are more convenient. Preferably, the sealing component is made of corrosion-resistant metal. The joint surface of concrete and metal can be in a vacuum state, without the need to use sealant, which is more environmentally friendly.

[0018] When the water storage chamber 5 needs to store water, the vacuum pump 2 is turned on through the valve control box 3 to evacuate the water storage chamber 5, so that the water storage chamber 5 is in a negative pressure state, and the air compressor 4 is turned on at the same time, and the air compressor 4 closes the diaphragm in the vacuum diaphragm valve 1 to ensure that the water storage chamber 5 maintains a long-term negative pressure vacuum state. At this time, the external air pressure is greater than the internal air pressure, and the water in the external water pool flows into the water storage chamber 5 until it reaches the predetermined water level. At this time, the air above the water level is still in a long-term negative pressure vacuum state.

[0019] When the water in the water storage chamber 5 is needed to flush the external water pool, the diaphragm of the vacuum diaphragm valve 1 is opened through the valve control box 3, so that the water storage chamber 5 is in contact with the external air. Since the water storage chamber 5 has been in a low-pressure state before, the external air pressure enters the water storage chamber 5 at this time, and the water in the water storage chamber 5 is pushed outward, thereby cleaning the water pool until the cleaning work is completed.

[0020] When flushing is not required, the water storage chamber 5 is always in a negative pressure state. When no sealing assembly is set, external air will penetrate the concrete wall and enter the water storage chamber 5, thereby destroying the internal negative pressure state and affecting the flushing effect during flushing. After the sealing assembly is set, the top plate 61 and the side plate 62 are fixed to the inner surface of the water storage chamber 5, and the water storage chamber 5 is sealed for a second time, so that external gas cannot enter the water storage chamber 5, so that the internal negative pressure state can be maintained for a long time, improving the flushing effect during flushing. At the same time, setting the sealing assembly into a modular installation structure can make installation, transportation and maintenance more convenient.

[0021] When installing the integral flushing device, the sealing assembly and the water storage chamber 5 are pre-buried together during the civil construction. After the civil construction is completed and the concrete strength is qualified, other equipment can be connected. Since the sealing assembly is constructed together with the civil construction, there is no need to conduct a sealing test on the water storage chamber 5 made of concrete, which shortens the installation period and improves the installation efficiency.

[0022] As a preferred example, the sealing assembly includes a top plate 61 and a side plate 62; the top plate 61 is fixed to the top inner wall of the water storage chamber 5, and the side plate 62 is fixed to the side inner wall of the water storage chamber 5; the top plate 61 is fixedly connected to the side plate 62. The top and side surfaces of the water storage chamber 5 are sealed twice by the top plate 61 and the side plate 62, so that the external air will not penetrate into the water storage chamber 5 through the wall, thereby improving the sealing effect.

[0023] As a preferred example, the number of the side panels 62 is N, where N≥3. Since the water storage chamber 5 is large, multiple side panels 62 are provided, so that the installation of the side panels 62 is more convenient, and there will be no situation where the installation is inconvenient due to the excessive size. On the same wall surface of the water storage chamber 5, multiple side panels 62 are provided in the vertical direction, and multiple side panels 62 are provided in the horizontal direction.

[0024] As a preferred example, each side panel 62 has a height of 2 to 2.5 m; and each side panel 62 has the same height, and two adjacent side panels 62 are fixedly connected. The height of each side panel 62 is set to 2 m to 2.5 m, so that the side panels 62 are easy to manufacture and transport, and the adjacent side panels 62 are fixed by bolt connection or welding, which has sufficient strength and better sealing.

[0025] As a preferred example, the distance between the bottom end of the side plate 62 located at the bottom and the bottom surface of the inner cavity of the water storage chamber 5 is 1.5 to 2 meters. When the water storage chamber 5 does not need to store water or flush, a portion of water will remain at the bottom. Therefore, there is no need to set the side plate 62 at the bottom of the water storage chamber 5. Water is used to seal the surroundings, and external air will not enter the water storage chamber 5. This can reduce the use of the side plate 62 and save costs.

[0026] As a preferred example, the sealing component 6 is made of corrosion-resistant metal. Since the sealing component 6 is used to block air from entering the water storage chamber 5 and has the function of storing water, the sealing component 6 is made of corrosion-resistant material, which can make the sealing component 6 more durable, increase the service life, and ensure the operational stability of the overall device.
