Description

Technical Field

[0001] This invention relates to the field of urban drainage treatment equipment technology, and in particular to a vacuum flushing device for use in regulating reservoirs or pumping stations. Background Technology

[0002] With urban development and the impact of floods, people are paying more and more attention to the construction of water storage tanks. Vacuum flushing devices, as a new type of flushing and sludge removal equipment in pump stations or water storage tanks, are increasingly being used due to their simple structure, convenient installation, and the fact that they do not need to be placed in the tank but only need to be installed on the surface of the wellhead.

[0003] During the use of existing vacuum rinsing devices, lightweight impurities and contaminants can easily enter the valve body of the vacuum rinsing device from the sealing surface when the device is working, causing the device to malfunction and, in severe cases, causing the entire vacuum rinsing device to fail.

[0004] Existing vacuum flushing devices are generally installed on the civil engineering foundation at the wellhead by applying adhesive. If a malfunction occurs and maintenance is required, the entire device often has to be disassembled. When it is repaired and reinstalled, adhesive needs to be applied again, which takes several days to dry. This often adds a lot of trouble to the maintenance of the vacuum flushing device. Summary of the Invention

[0005] To address the technical problems existing in the above-mentioned vacuum cleaning systems, the purpose of this invention is to propose a vacuum flushing device for use in regulating tanks or pumping stations. The membrane chamber is designed to be higher than the installation surface by a certain distance, thereby effectively blocking external impurities and contaminants from entering the valve body of the vacuum cleaning system, and effectively avoiding equipment failure caused by external impurities and contaminants entering the equipment.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] A vacuum flushing device for use in regulating reservoirs or pumping stations includes a vacuum diaphragm cover, a diaphragm cover base, and a transition plate;

[0008] The transition plate has a circular opening in the middle that matches the wellhead, and its surface is fixed to the surface of the pump station or storage tank wellhead by sealant and chemical anchors.

[0009] The membrane cover base includes a base plate, a shaped support plate, a seat cylinder, a membrane cover sealing ring, and a membrane cover fixing ring; the base plate is annular, and the bottom end of the seat cylinder is fixedly connected to the annular opening of the base plate; the shaped support plate includes several of them, which are distributed in a ring and fixed on the base plate, the top edge of the shaped support plate is a bevel, and its lowest point is connected to the top edge of the seat cylinder, and its highest point is fixedly connected to the membrane cover fixing ring, and the membrane cover sealing ring is fixed on the seat cylinder;

[0010] The vacuum diaphragm cover includes a membrane cavity cover plate, a diaphragm, a vent pipe, a diaphragm base plate, and a diaphragm pressure plate. The top of the membrane cavity cover plate is provided with a vacuum extraction chamber and a vacuum rupture pipe. The top of the vent pipe is fixed to the membrane cavity cover plate and communicates with the extraction chamber. The diaphragm is circular, with its center fitted onto the bottom end of the vent pipe and fixed to the diaphragm base plate by the diaphragm pressure plate. Its edge is fixed to the membrane cavity cover plate, forming a sealed membrane cavity between the diaphragm and the membrane cavity cover plate. The bottom end of the vacuum rupture pipe communicates with the membrane cavity. The membrane cavity cover plate is fixed to the membrane cover fixing ring. The diaphragm base plate is pressed onto the membrane cover sealing ring.

[0011] In a further preferred technical solution, the base plate is fixed to the transition plate by bolts, and a base plate sealing ring is provided between the two.

[0012] A further optimized technical solution is provided, wherein the membrane cover sealing ring is provided with an annular sealing groove, and an annular sealing ring is installed in the annular sealing groove, so that when the diaphragm chassis presses the membrane cover sealing ring, the two can be sealed.

[0013] To further optimize the technical solution, a perforated plate is provided between the irregularly shaped support plates.

[0014] In a further preferred technical solution, the base plate is provided with a liquid level inspection port, and a liquid level inspection cover is provided on the liquid level inspection port.

[0015] Further optimization of the technical solution involves opening several weight-reducing holes on the irregularly shaped support plate to facilitate the reduction of the overall weight of the equipment.

[0016] In a further optimized technical solution, a cover sealing ring is provided between the membrane cavity cover plate and the membrane cover fixing ring.

[0017] In a further preferred embodiment, the vacuum diaphragm cover also includes a housing, which covers the vacuum extraction chamber of the diaphragm cover plate.

[0018] In a further optimized technical solution, a negative pressure gauge is installed on the top of the vacuum extraction chamber.

[0019] The beneficial effects of this invention are:

[0020] The membrane chamber in this design is raised to a certain height, with a certain distance between it and the installation platform. This effectively prevents external impurities and contaminants from entering the valve body of the vacuum cleaning device, thus effectively solving the problem of equipment failure caused by external impurities and contaminants entering the equipment. Furthermore, a base plate is added below it. When the vacuum cleaning device needs maintenance, only the vacuum cleaning device on the base plate needs to be removed for maintenance, without the need to disassemble the transition plate. When reinstalling after maintenance, the vacuum cleaning device can be installed on the transition plate without the need for applying glue or waiting for the glue to dry. This not only reduces the workload of maintenance and saves maintenance costs, but also greatly shortens the maintenance time. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figure 1 and 2As shown, a vacuum flushing device for use in regulating reservoirs or pumping stations can be divided into three parts in terms of function: a transition plate 1, a membrane cover base 2, and a vacuum diaphragm cover 3.

[0029] like Figure 3 As shown, the transition plate 1 has a circular opening in the middle that matches the wellhead, and its surface is fixed to the surface of the pump station or regulating tank wellhead by sealant and chemical anchors. The wellhead surface can be fitted with embedded parts or constructed as a civil engineering structure.

[0030] like Figure 2 and 4 As shown, the membrane cover base 2 is fixed to the transition plate 1 by bolts. The specific structure of the membrane cover base 2 is as follows: Figure 2 As shown: Includes: a base plate 21, a shaped support plate 22, a seat cylinder 23, a membrane cover sealing ring 24, and a membrane cover fixing ring 25; the base plate 21 is annular, and the bottom end of the seat cylinder 23 is fixedly connected to the annular opening of the base plate 21; the base plate 21 is fixed to the transition plate 3 by bolts, and a base plate sealing ring 11 is provided between the two, such as... Figure 3 The irregularly shaped support plates 22 comprise several of each, arranged in a ring and fixed to the base plate 21. The top edge of each support plate 22 is beveled, and its lowest point is connected to the top edge of the seat cylinder 23. Its highest point is fixedly connected to the membrane cover fixing ring 25. The membrane cover sealing ring 24 is fixed to the seat cylinder 23. An annular sealing groove is provided on the annular surface of the membrane cover sealing ring 24, and an annular sealing ring 27 is installed within this groove. Furthermore, a perforated plate 26 is provided between adjacent irregularly shaped support plates 22.

[0031] In addition, a liquid level inspection port is provided on the base plate 21, and a liquid level inspection cover plate 28 is provided on the liquid level inspection port.

[0032] In addition, several weight-reducing holes are provided on the irregular support plate 22 to facilitate the reduction of the overall weight of the equipment.

[0033] like Figure 2 and 5 As shown, the vacuum diaphragm cover 3 includes a membrane cavity cover plate 31, a diaphragm 32, a vent pipe 33, a diaphragm base plate 34, and a diaphragm pressure plate 35. The top of the membrane cavity cover plate 31 is provided with a vacuum extraction chamber 311 and a vacuum rupture pipe 312. The top of the vent pipe 33 is fixed to the membrane cavity cover plate 31 and communicates with the extraction chamber 311. The diaphragm 32 is circular, with its center fitted around the bottom end of the vent pipe 33 and fixed to the diaphragm base plate 34 by the diaphragm pressure plate 35. The edge of the diaphragm 32 is fixed to the membrane cavity cover plate 31, thus forming a sealed membrane cavity between the diaphragm 32 and the membrane cavity cover plate 31. The bottom end of the vacuum rupture pipe 312 communicates with the membrane cavity. The membrane cavity cover plate 31 is fixed to the membrane cover fixing ring 25. The diaphragm base plate 34 presses against the membrane cover sealing ring 24.

[0034] A cover sealing ring 36 is provided between the membrane cavity cover plate 31 and the membrane cover fixing ring 25.

[0035] The vacuum diaphragm cover 3 also includes a cover 37, which covers the vacuum extraction chamber 311 of the diaphragm cover plate 31.

[0036] The top of the vacuum pumping chamber 311 is equipped with a negative pressure gauge 313, which allows the operator to monitor the pressure changes in the well chamber in real time.

[0037] The working principle of this solution is as follows:

[0038] When the water level in the storage tank submerges the lower end of the well chamber, the vacuum diaphragm cover, the well chamber, and the water in the storage tank are in a completely sealed state. If the vacuum pump extracts air from the well chamber through the vacuum extraction chamber, a negative pressure will be formed in the well chamber. At this time, the water in the storage tank will be "forced" into the well chamber by atmospheric pressure. When the level gauge detects that the water level has risen to the predetermined water level height, the solenoid valve will be turned off, the vacuum pump will stop, and the system will enter a pressure-holding state.

[0039] After the storage tank is emptied, a lot of sludge and debris will remain at the bottom of the tank. This sludge and debris needs to be removed. At this time, the control program switches the solenoid valve to the vacuum rupture pipe 312 to draw air from the membrane chamber. Under the pressure of the external atmospheric pressure, the diaphragm base 34 is lifted, thereby breaking the sealing environment between the diaphragm base 34 and the well chamber. External gas enters the well chamber, and under the action of atmospheric pressure, the water that has been stored in the well chamber will be released instantly, forming a large water shock wave. The sludge and debris left at the bottom of the storage tank are washed away by the water shock wave, thus achieving a flushing of the storage tank.

[0040] In practical engineering applications, multiple vacuum rinsing devices of this technical solution can be set up in corresponding working areas according to actual working conditions and combined into a network system to achieve the best working efficiency and the most economical operation.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
