Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and more specifically, to a mobile sewage cleaning device. Background Technology

[0002] In the field of wastewater treatment, traditional stationary treatment facilities are typically suitable for large-scale centralized treatment, but they suffer from long construction cycles, high costs, and an inability to flexibly respond to sudden pollution or localized wastewater accumulation. For small-scale or temporary wastewater (such as pipe leaks, construction site flooding, rainwater runoff from low-lying areas, etc.), existing technologies mostly employ water pumps in conjunction with simple filtration devices, but these methods generally have shortcomings.

[0003] Existing mobile wastewater treatment devices can only transfer wastewater or perform primary filtration, failing to simultaneously complete solid-liquid separation, wastewater drying, and volume reduction, leading to increased subsequent transportation and disposal costs. They typically rely on a single filter or gravity filtration, which is prone to clogging and struggles to handle wastewater with high impurity levels, requiring frequent shutdowns for cleaning. Furthermore, existing mobile wastewater treatment devices often require manual intervention for air pressure control, water level monitoring, and equipment start-up and shutdown, resulting in low automation, increased operational risks, and a lack of noise suppression design, making them unsuitable for use in sensitive areas (such as residential areas and hospitals). Utility Model Content

[0004] To address the aforementioned issues, this application proposes an integrated mobile cleaning device that combines modular design with negative pressure suction, multi-stage filtration, and compression drying technologies to achieve efficient cleaning and volume reduction of contaminants. It is also equipped with an intelligent control system and noise reduction components to enhance portability, processing efficiency, and environmental friendliness.

[0005] This application discloses a mobile wastewater cleaning device, characterized in that it comprises: a housing; a water pumping pipe connected to the upper part of the housing for pumping wastewater into the housing; and a drain pipe connected to the lower part of the housing for discharging filtered water; wherein the housing includes an outer shell, a partition, a compressor, and a filter box; wherein the partition divides the internal space of the outer shell into a wastewater discharge chamber and a drying chamber, and has an opening near the top of the outer shell to allow the wastewater discharge chamber to communicate with the drying chamber; wherein the compressor is disposed in the drying chamber and connected to the wastewater discharge chamber via the opening of the partition to extract air from the wastewater discharge chamber; and wherein the filter box is detachably disposed at the bottom of the wastewater discharge chamber for filtering dirt from the wastewater.

[0006] According to an optional embodiment, the mobile cleaning device includes a plurality of sliding wheels; and the plurality of sliding wheels are rotatably fixed to the bottom of the housing for moving the housing.

[0007] According to an optional embodiment, the housing includes a control panel; and the control panel is disposed on the side wall of the housing and connected to the compressor for controlling the start and stop of the compressor and adjusting the inlet and outlet states of the drain chamber.

[0008] According to an optional implementation, the control panel integrates a display module for displaying the compressor's operating status and the opening / closing status of the water inlet and outlet in real time.

[0009] According to an optional embodiment, the housing includes a water inlet and a drain outlet; the water inlet is located on the upper part of the outer shell and is used to connect the water pump pipe and the sewage discharge chamber; the drain outlet is located on the lower part of the outer shell and is used to connect the drain pipe and the sewage discharge chamber; and the opening and closing of the water inlet and the drain outlet are automatically controlled or manually adjusted by the control panel.

[0010] According to an optional embodiment, the filter box is located against the drain outlet and has multiple filter screens with different pore sizes inside; the pore size of the filter screen near the drain outlet is smaller than that of the filter screen away from the drain outlet.

[0011] According to an optional embodiment, the pumping pipe is connected to a rigid or flexible extension pipe by threads or clamps to adapt to sewage tanks of different depths; and the pumping pipe is provided with a filter or sieve at its end to prevent large debris in the sewage from being sucked into the mobile cleaning device.

[0012] According to an optional embodiment, the housing includes an exhaust pipe and a muffler; one end of the exhaust pipe is connected to the compressor, and the other end extends to the outside of the housing to discharge the gas drawn out by the compressor to the outside of the housing; and the muffler is disposed on the outer wall of the exhaust pipe to reduce exhaust noise.

[0013] According to an optional embodiment, the housing includes a negative pressure gauge; and the negative pressure gauge is disposed on the top of the housing and communicates with the drain chamber for monitoring the air pressure in the drain chamber.

[0014] According to an optional embodiment, the housing includes a water level gauge; and the water level gauge is disposed on the side wall of the housing and communicates with the drain chamber for monitoring the liquid level height in the drain chamber.

[0015] The mobile cleaning device according to this application divides the space into a sewage discharge chamber and a drying chamber through a partition inside the housing. A compressor creates a negative pressure environment in the drying chamber, causing the sewage discharge chamber to generate suction that draws sewage into the housing via a pump pipe. Once in the sewage discharge chamber, the sewage undergoes gradient filtration through a multi-stage filter box at the bottom. The fine filter near the drain outlet effectively intercepts tiny particles, while the coarse filter further away filters out larger impurities. This graded filtration method significantly improves filtration efficiency and extends the filter lifespan. The filtered clean water is discharged through the drain pipe, while the trapped dirt accumulates in the sewage discharge chamber. Once a certain amount has accumulated, it can be cleaned by opening the housing. The control panel allows real-time monitoring and adjustment of the compressor's operating status, the opening and closing of the inlet and outlet, and the air pressure and liquid level in the sewage discharge chamber, enabling automated operation. The silencer effectively reduces noise pollution from the compressor exhaust, making the device suitable for environments with high noise requirements. The detachable filter box design facilitates regular cleaning or replacement of the filter, ensuring continuous and efficient filtration performance. The omnidirectional casters mounted at the bottom allow the entire device to move flexibly, making it suitable for cleaning and wastewater treatment needs in different locations. This device integrates wastewater suction, staged filtration, waste collection, air pressure control, noise suppression, and intelligent monitoring. It boasts advantages such as compact structure, simple operation, excellent filtration effect, and strong environmental adaptability. It effectively solves the problems of traditional mobile wastewater treatment equipment, such as limited functionality, low efficiency, and complex operation, making it particularly suitable for municipal maintenance, industrial sites, and other situations requiring rapid wastewater treatment.

However, it should be understood that the drawings are for illustrative purposes only and are not intended to limit the scope of this application. Detailed Implementation

[0020] Exemplary embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and is not limited to the embodiments shown in the drawings. Rather, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0021] Figure 1 This is a perspective view of the mobile cleaning device according to this application. Figure 1 As shown, the mobile cleaning device 1 includes a housing 11, multiple sliding wheels 12, a water pumping pipe 13, and a drain pipe 14.

[0022] The sliding wheels 12 are rotatably fixed to the bottom of the housing 11 to assist the housing 11 in moving horizontally on the ground. A water suction pipe 13 is connected to the upper part of the housing 11. A drain pipe 14 is connected to the lower part of the housing 11. During operation of the mobile cleaning device 1, wastewater is drawn into the housing 11 via the water suction pipe 13 and then filtered within the housing 11. The filtered water is discharged via the drain pipe 14. In this way, impurities in the water can be filtered into the housing 11. When the impurities accumulate to a certain level, the housing 11 can be opened to collect and discharge the impurities. Figure 1 Only a portion of the pumping pipe 13 is shown in the diagram. The pumping pipe 13 can be connected to a rigid or flexible extension pipe via threads or clamps to accommodate sewage tanks of different depths. The pumping pipe 13 may also have a filter or screen at its outer end (the side closer to the sewage) to prevent oversized debris in the sewage from being sucked into the mobile cleaning device 1.

[0023] Figure 2 This is a cross-sectional view of the mobile cleaning device according to this application. Figure 2 As shown, the housing 11 includes an outer shell 111, a partition 112, a compressor 113, an exhaust pipe 114a, a silencer 114b, a water inlet 115a, a drain outlet 115b, a filter box 116, a control panel 117, a negative pressure gauge 118, and a water level gauge 119.

[0024] A partition 112 is disposed inside the housing 111, dividing the internal space of the housing 111 into a drain chamber 111a and a drying chamber 111b. The partition 112 is joined to the inner wall of the housing 111, with an opening only near the top of the housing 111 to maintain airflow between the drain chamber 111a and the drying chamber 111b. A compressor 113 is disposed in the drying chamber 111b of the housing 111 and is connected to the drain chamber 111a via the opening in the partition 112 to extract air from the drain chamber 111a. An exhaust pipe 114a is connected at one end to the compressor 113 and at the other end to the outside of the housing 111 to discharge the gas extracted by the compressor 113 to the outside of the housing 111. A muffler 114b is disposed on the outer wall of the exhaust pipe 114a to reduce noise caused by vibration of the exhaust pipe 114a. A water inlet 115a is disposed at the upper part of the housing 111 and connects the water inlet pipe 13 to the drain chamber 111a. The drain outlet 115b is located at the lower part of the outer casing 111 and connects the drain pipe 14 and the sewage discharge chamber 111a. When the air pressure in the sewage discharge chamber 111a decreases, the drain outlet 115b closes, and the sewage enters the sewage discharge chamber 111a through the pumping pipe 13 and the inlet 115a under the action of the air pressure difference.

[0025] A filter box 116 is located at the bottom of the drain chamber 111a of the outer casing 111, abutting against the drain outlet 115b. The filter box 116 contains multiple filter screens with different pore sizes. The filter screens closer to the drain outlet 115b have smaller pore sizes, while those farther from the drain outlet 115b have larger pore sizes. When it is necessary to filter the wastewater in the drain chamber 111a, the inlet 115a is closed, the drain outlet 115b is opened, and the compressor 113 stops operating. The wastewater in the drain chamber 111a enters the filter box 116 under gravity and, after being filtered, is discharged from the drain pipe 14 through the drain outlet 115b.

[0026] The filter box 116 can be removed from the housing 111 to clean accumulated dirt. A control panel 117 is located on the side wall of the housing 111 and connected to the compressor 113, inlet 115a, and drain 115b to display the status of the compressor 113, inlet 115a, and drain 115b, control the start and stop of the compressor 113, and control the opening and closing of inlet 115a and drain 115b. Optionally, the opening and closing of inlet 115a and drain 115b can also be manually controlled (e.g., via a valve). A negative pressure gauge 118 is located on the top of the housing 111 and connected to the drain chamber 111a to display the air pressure in the drain chamber 111a. A water level gauge 119 is located on the side wall of the housing 111 and communicates with the drain chamber 111a to display the liquid level in the drain chamber 111a.
