Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sanitation equipment, in particular to a cleaning and sewage suction tank, a use method thereof and a cleaning and sewage suction vehicle. BACKGROUND

[0002] In the mainstream scheme of the current market, the tank body is divided into two cabins, the front cabin is a clean water tank, and the rear cabin is a sewage tank, and the volume is constant. The clean water tank is mainly used for underground pipeline dredging, and the sewage tank is mainly used for recycling sewage and silt in the pipeline. When the clean water dredging is finished, the clean water tank is in an empty state, and the sewage tank is full. In actual use, due to the small volume of the tank body, and the large amount of sewage and silt in the underground pipe network, the amount of silt and sewage transported at a time is limited, and several trips are required. Sometimes the place for centralized treatment of sewage and silt is far from the operation site, and the operation efficiency of the vehicle is very low.

[0003] Therefore, in order to solve the technical defects of the small volume of the clean water tank and the sewage tank in the related art of the cleaning and sewage suction vehicle, and the low transfer efficiency, it is urgent to provide a cleaning and sewage suction tank with variable tank capacity, a use method thereof, and a cleaning and sewage suction vehicle provided with the improved cleaning and sewage suction tank. SUMMARY

[0004] Object: In order to overcome the deficiencies in the prior art, the present application provides a cleaning and sewage suction tank, a use method thereof, and a cleaning and sewage suction vehicle, the volume of clean water and sewage in the cleaning and sewage suction tank is variable, and the operation efficiency is improved.

[0005] To solve the above technical problems, the technical scheme adopted by the present application is:

[0006] In a first aspect, the present application provides a cleaning and sewage suction tank, comprising a water bag, a partition plate assembly, a vacuum suction system and a high-pressure waterway system; The water bag is located inside the tank body of the cleaning and sewage suction tank, and is connected with a water inlet on the tank body, and is used for storing clean water; The partition plate assembly comprises a partition plate frame and a filter screen, the partition plate frame is slidably connected with the inside of the tank body, and the filter screen is installed in the inside of the tank body through the partition plate frame, and is used for blocking solid impurities in the sewage; The water bag is connected with the partition plate frame through a connecting support, and the connecting support is used for supporting the water bag; the water bag is gradually unfolded in the process of adding clean water, and drives the partition plate frame to slide away from the water inlet end, so as to increase the clean water volume and reduce the sewage volume; the water bag discharges clean water and gradually shrinks in the cleaning and sewage suction process, and the partition plate frame moves to the water inlet end under the driving of the water bag shrinkage, so as to reduce the clean water volume and increase the sewage volume; The vacuum suction system is used for sucking the inside of the tank body into a vacuum state, and sucking the sewage into the tank body based on atmospheric pressure; The high-pressure waterway system is used for pressurizing and spraying the clean water in the water bag.

[0007] The water bag is a self-shrinking water bag. When water is added, the water bag expands to fill the entire tank body, and the volume of clean water is greatly increased compared with the traditional cleaning and sewage suction tank, thereby prolonging the high-pressure cleaning time. After cleaning, the water bag shrinks to a very small state, and the entire tank body can be used to store and transport sewage, silt and other sewage, thereby improving the transportation efficiency and use efficiency of the vehicle and saving energy.

[0008] In some embodiments, the partition frame is connected to the inside of the tank body through a roller sliding connection. The roller is used to fit the partition frame to the inner wall of the tank body and maintain the stability of the partition assembly structure during the expansion and contraction of the water bag.

[0009] In some embodiments, a sealing gasket is installed between the filter screen and the partition frame.

[0010] The sealing gasket prevents solid impurities such as silt from entering the side of the water bag, protecting the water bag from wear or physical cutting damage. The partition frame provides structural support. The roller ensures that the partition frame is always closely fitted to the inner wall of the tank body, preventing it from being tilted by external forces and ensuring the stability of the structure. When water is added, the water bag expands and pushes the partition assembly to move backward. When the water volume in the water bag gradually decreases, the partition assembly is pulled to move toward the water inlet end, thereby increasing the volume of sewage.

[0011] In some embodiments, the vacuum suction system includes a vacuum pump and a sewage suction pipe. The vacuum pump is used to create a vacuum state in the inside of the tank body, and atmospheric pressure transports the sewage to the inside of the tank body through the sewage suction pipe.

[0012] In some embodiments, the high-pressure water system includes a high-pressure pump, a water pipe and a nozzle. The high-pressure pump takes water from the water bag, and the water pipe and the nozzle realize the cleaning effect.

[0013] In some embodiments, a ball valve is provided at the water inlet for controlling the opening and closing of the water bag.

[0014] The water bag is filled with water through a fire hose, and the ball valve is closed after the water is filled to prevent clean water from flowing out.

[0015] In some embodiments, a sewage outlet is provided at the lower part of the tank body away from the water inlet end for discharging the sewage in the tank body.

[0016] In a second aspect, the present application provides a cleaning and sewage suction vehicle, which is installed with the cleaning and sewage suction tank as described in the first aspect. The vacuum suction system and the high-pressure water system are installed on the chassis of the cleaning and sewage suction vehicle.

[0017] The chassis of the cleaning and sewage suction vehicle carries the tank body and other structural components, and provides power for the high-pressure water system and the vacuum suction system.

[0018] In a third aspect, the present application provides a method for cleaning a sewage suction tank as described in the first aspect, comprising: opening the ball valve, adding clean water to the water bag through the fire pipe, closing the ball valve after the water is added; starting the high-pressure water system and the vacuum suction system, the high-pressure water pump taking water from the water bag, pressing the water through the chassis power, cleaning through the nozzle, the vacuum pump sucking the tank body into a vacuum state, atmospheric pressure transporting the sewage wastewater to the tank body through the sewage suction pipe; after cleaning, closing the high-pressure water system and the vacuum suction system; opening the sewage outlet, closing the sewage outlet after discharging the sewage wastewater.

[0019] Beneficial effects: the cleaning sewage suction tank, the method for cleaning the sewage suction tank, and the cleaning sewage suction vehicle provided by the present application can change the volume of clean water and sewage wastewater in the tank body through the water bag built-in in the tank body, which greatly increases the volume of clean water and sewage wastewater compared with the traditional cleaning sewage suction tank; when the cleaning sewage suction tank is filled with clean water, the water bag is expanded by adding water, which can fill the entire tank body, greatly increasing the volume of clean water, effectively prolonging the operation time of pipeline dredging; after the pipeline is dredged, the clean water is gradually used up, and the retractable water bag is automatically retracted, effectively increasing the volume of sewage wastewater, and greatly improving the transfer efficiency.

Detailed Implementation

[0026] The technical solutions in 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use.

[0027] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may include different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] This embodiment provides a cleaning suction tank, such as Figure 1 and Figure 2 As shown, it includes a chassis 1, a vacuum suction system 2, a water bladder 4, a partition assembly 6, and a high-pressure water system 5.

[0030] like Figure 3 As shown, the baffle assembly 6 includes a baffle frame 61 and a filter screen 63, the filter screen 63 being installed inside the tank 7 via the baffle frame 61; as Figure 4 As shown, a sealing gasket 62 is installed between the partition frame 61 and the filter screen 63; the partition frame 61 is slidably connected to the inside of the tank body 7 via rollers 64.

[0031] The water bladder 4 is located inside the tank body 7 of the cleaning and suction tank and is connected to the water inlet 3 on the tank body 7. A ball valve 71 is provided at the water inlet 3. Furthermore, the water bladder 4 is connected to the partition frame 61 through the connecting bracket 65.

[0032] The vacuum suction system 2 includes a vacuum pump and a suction pipe. The vacuum pump is used to create a vacuum inside the tank 7, and the suction pipe is used to suction the wastewater 92.

[0033] The high-pressure water system 5 includes a high-pressure pump, water pipes, and nozzles. The high-pressure pump draws water from the water bladder 4 and then uses the water pipes and nozzles to perform the cleaning function.

[0034] The cleaning suction tank has a drain outlet 8 located at the lower end of the end away from the water inlet 3, which is used to drain the cleaning wastewater 92 from the tank body 7.

[0035] Furthermore, after the water bladder 4 is filled with clean water 91, it expands to fill the entire tank 7. During the process of adding clean water 91, the water bladder 4 gradually unfolds, pushing the partition frame 61 to slide away from the water inlet 3. The volume of clean water 91 is greatly increased compared with related technologies, thus extending the cleaning time. During the cleaning and suction process, the water bladder 4 discharges clean water 91 and gradually shrinks. The partition frame 61 moves towards the water inlet 3 under the action of the shrinking water bladder 4. After the clean water 91 is used up, the water bladder 4 shrinks to a very small state. At this time, the entire tank 7 can be used to store and transport cleaning wastewater 92. The volume of cleaning wastewater 92 is greatly improved compared with related technologies, which improves the efficiency of operation and is energy-saving and efficient.

[0036] At least one embodiment also provides a method of using a cleaning suction tank, including: Open ball valve 71 and add clean water 91 to water bag 4 through fire pipe. Water bag 4 expands and pushes partition assembly 6 to slide towards drain outlet 8. After adding water, close ball valve 71. The high-pressure water system 5 and vacuum suction system 2 are activated. The high-pressure water pump draws water from the water bladder 4 and pressurizes the water through the chassis 1. The water is then used to clear sludge and sand from the underground pipe network through nozzles. The vacuum pump creates a vacuum in the tank 7, and atmospheric pressure transports the wastewater 92 to the inside of the tank 7 through the suction pipe on the vehicle. At this time, the volume of the water bladder 4 decreases, and the volume of the wastewater 92 increases. The baffle assembly 6 slides towards the water inlet 3. During this process, the wastewater 92 is filtered by the filter screen 63, and the water bladder 4 contacts the filtered water 93 without contacting the solid impurities 94 in the wastewater 92. After cleaning is completed, the high-pressure water system 5 and vacuum suction system 2 are shut off. Open drain outlet 8, discharge wastewater 92, and then close drain outlet 8.

[0037] At least one embodiment also provides a cleaning and vacuuming vehicle, such as Figure 1 and Figure 2As shown, the cleaning and vacuuming truck is equipped with a cleaning and vacuuming tank. The vacuum suction system 2 and the high-pressure water system 5 are mounted on the chassis 1 of the cleaning and vacuuming truck.

These terms are used only for the convenience of describing the invention and for simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the invention.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
