[0046] Please refer to Figures 1 to 8 , Figure 1A schematic diagram of the structure of a sewage dredging and purification vehicle provided in a specific embodiment of the utility model; Figure 2 for Figure 1 A top view of Figure 3 for Figure 1 Side view of Figure 4 for Figure 1 Schematic diagram of the sewage sedimentation device; Figure 5 is another view of the sewage sedimentation device; Figure 6 It is a schematic diagram of the clean water tank and the flocculation tank; Figure 7 It is a schematic diagram of a medicine mixing box; Figure 8 Schematic diagram of the screw stacking machine.

[0047] The dredging sewage suction and purification vehicle provided by the utility model comprises a sewage suction device installed on a chassis 1, a sewage sedimentation device connected to the sewage suction device, a flocculation tank 4 connected to the sewage sedimentation device, a medicine mixing tank 8 connected to the inlet of the flocculation tank 4, a medicine box 27 and a clean water tank 5 connected to the medicine mixing tank 8, a screw stacking machine 2 connected to the discharge port of the flocculation tank 4, and a generator set 6 that shares a fuel tank with the chassis of the dredging sewage suction and purification vehicle to generate electricity; the dredging sewage suction and purification vehicle also includes:

[0048] An air compressor installed on the chassis 1 to inflate the water-blocking airbags, which block the two ends of the pipeline;

[0049] The high-pressure flushing device is installed on the chassis 1 and is used to clean the sludge inside the pipeline and the sludge in the external environment.

[0050] In the above structure, the dredging and sewage suction and purification vehicle is equipped with a chassis 1 and a body 21, and the components on the vehicle are installed on the chassis 1 to realize the assembly and transportation of the entire equipment. The components are installed in the body 21, and the body 21 protects the internal components.

[0051] The sewage pumping device is installed on the chassis 1. The sewage pumping device is powered by the sewage settling device, and the sewage pumping device sucks the sewage into the sedimentation box 3 of the sewage settling device. The sewage is initially separated in the sedimentation box 3 to achieve solid-slag separation. Large impurities are left in the upper part of the sedimentation box 3 to be taken out later. The flocculation box 4 is connected to the sewage settling device, and the sewage in the sedimentation box 3 enters the flocculation box. At the same time, the medicine box 27 and the clean water tank 5 are connected to the medicine stirring box 8, and the clean water flows into the medicine stirring box 8. The medicine in the medicine box 27 is sent to the medicine stirring box 8 and mixed with the clean water. The medicine and the clean water enter the medicine stirring box 8 according to the set ratio and are mixed evenly. The medicine stirring box 8 is connected to the inlet of the flocculation box 4, and the dosing pump 11 extracts the medicine and transports it to the flocculation box 4 through the medicine outlet pipe 29, and the mixed medicine enters the flocculation box 4. In the flocculation box 4, the sewage and the medicine are mixed and stirred, and the medicine is added in proportion to achieve the secondary stirring cycle of the sludge water and the PAM cationic medicine. The sewage and the medicine in the flocculation box 4 are mixed to a flocculated state, and enter the feed port 24 of the snail stacking machine 2 from the discharge port of the flocculation box 4. The snail stacking machine 2 includes a spiral device 25, which separates the muddy water. The clean water flows out from the bottom of the snail stacking machine 2 and can be returned to the municipal sewage pipeline. The sludge is pushed by the spiral device 25 to the discharge port 23 of the snail stacking machine 2 for discharge and can be bagged or boxed.

[0052] The dredging and sewage suction and purification vehicle is provided with a generator set 6, which shares a fuel tank with the chassis of the dredging and sewage suction and purification vehicle. The generator set 6 can generate electricity by itself to realize the power supply of the electrical components of the whole vehicle. At the same time, the dredging and sewage suction and purification vehicle is also equipped with an aviation connector 22, which is connected to the municipal fire hydrant to realize the external connection of the municipal power supply to ensure the power supply demand of the vehicle after the generator set 6 fails.

[0053] Municipal dredging operations require the upstream and downstream sections of the pipeline in the dredging section to be blocked by water-blocking airbags. In the prior art, a tool cart is equipped with a separate air compressor on the tool cart to supply air to the water-blocking airbags. This application integrates the air supply function into this device. The air compressor is installed on the chassis 1. The air compressor inflates the water-blocking airbags, which are blocked at both ends of the pipeline, providing an air source for the water-blocking airbags before the dredging operation, eliminating the air compressor of the tool cart.

[0054] The dredging sewage suction and purification vehicle is equipped with a high-pressure flushing device which is not available in existing equipment. The high-pressure clean water generated by the high-pressure flushing device dredges the accumulated sludge in the municipal pipeline through the dredging hose roller 9 to form a sludge-water mixture of a certain concentration. At the same time, the sludge-water mixture is pumped into the sedimentation box 3 through the suction of the sewage suction device.

[0055] The high-pressure flushing device can not only perform high-pressure and large-volume dredging on municipal pipelines, but also realize one vehicle that can perform both high-pressure dredging and sludge purification. Compared with the existing method in which the sludge water after dredging is sucked back into the sludge tank by the sewage suction truck and needs to be transported to the urban sludge treatment station for unloading and centralized treatment, in addition to on-site sludge drying treatment of septic tanks, it can also perform continuous dredging and online sludge treatment on municipal pipelines. One vehicle can perform multiple functions, saving time, effort and money. The high-pressure flushing device can also clean the external environment and sludge on various components to ensure a clean environment and equipment.

[0056] In a preferred embodiment, the dredging and sewage suction and purification vehicle is equipped with a ladder 13, through which the staff can conveniently get on and off the vehicle for operation and maintenance.

[0057] The dredging sewage suction and purification vehicle provided by the utility model integrates flushing, sewage treatment and intelligent control, which changes the existing municipal dredging operation mode, realizes continuous operation on site directly at the operation site, and completes the operation with one vehicle, so that sludge can be dried while dredging, and sewage can be treated efficiently; it provides an air source for the water blocking and sealing airbags before the dredging operation, and provides electricity and hydraulic power sources for on-site construction equipment, replacing the traditional sewage suction vehicles and tool vehicles, reducing tool vehicles, achieving multi-functionality in one vehicle, reducing costs and increasing efficiency; compared with the sewage suction vehicle + tool vehicle, a purification vehicle requires one driver, reducing construction vehicles and construction personnel, and reducing vehicle management and personnel management costs.

[0058] Based on the above specific embodiments, the sewage extraction device includes:

[0059] When the sludge concentration in the pipeline is greater than or equal to a preset concentration, the slurry pump 10 for sucking sludge is started;

[0060] When the sludge concentration in the pipeline is lower than a preset concentration, the sewage suction vacuum pump 14 is turned on for sewage suction work.

[0061] In practical applications, the slurry pump 10 has a sewage suction capacity of up to 50 meters, and the slurry pump 10 has a large power, which can be used to extract sludge water in municipal pipelines. The sewage suction vacuum pump 14 has a sewage suction capacity of 30 meters, which can be used to extract sludge water for dredging municipal pipelines.

[0062] For the continuous operation of municipal dredging online, the dredging sewage suction and purification vehicle has a strong sewage suction capacity, and is equipped with a slurry pump 10 and a sewage suction vacuum pump 14. The slurry pump 10 and the sewage suction vacuum pump 14 will not be used at the same time. This configuration is to adapt to different working conditions and realize the two functions of sucking sludge and water mixture. Different working conditions refer to working conditions with different sludge concentrations. If the sludge concentration is high, the slurry pump 10 must be used; for sewage with low concentration, the vacuum pump has higher suction efficiency.

[0063] In a preferred embodiment, the hydraulic hose drum 12 only releases and retracts the hydraulic hose line that drives the slurry pump 10 , and the hydraulic hose drum 12 drives the hydraulic motor of the slurry pump 10 .

[0064] Based on the above-mentioned specific embodiments, the sewage sedimentation device includes a sedimentation box 3 with an inlet located at the top, a filter plate 30 located below the inlet, a spiral conveying device arranged at the sedimentation port on the bottom surface of the sedimentation box 3, and a water pump 26 arranged in the sewage cavity between the filter plate 30 and the sedimentation port, and the water outlet of the water pump 26 is connected to the inlet of the flocculation box 4.

[0065] In a specific embodiment, the inlet of the sedimentation box 3 is located at the top, and the sewage enters the sedimentation box 3 from the inlet. The filter plate 30 is located directly below the inlet, and the sewage falls on the filter plate 30. The impurities in the sewage cannot pass through the filter plate 30 and are isolated. The impurity port is opened to take out the large impurities. The impurities on the filter plate 30 and the sewage can pass through the filter holes of the filter plate 30. Under the action of gravity, the sand and gravel in the sewage pass through the filter holes and settle to the bottom surface of the sedimentation box 3. A sedimentation port is provided on the sedimentation box 3, and a spiral conveying device is provided at the sedimentation port on the bottom surface of the sedimentation box 3. The spiral pushing device 28 is started to push the impurities to the sewage outlet by the spiral. The water pump 26 is provided in the sewage cavity between the filter plate 30 and the sedimentation port. The outlet of the water pump 26 is connected to the inlet of the flocculation box 4, and the water pump 26 sucks the sewage into the flocculation box 4 to mix with the medicine.

[0066] In the above embodiment, the sewage sedimentation device separates sewage and impurities through the filter plate 30, separates sand and gravel through the screw conveyor, and finally only sewage enters the flocculation box 4, thereby improving the purity of sewage and making the sewage and the medicine react more efficiently and fully.

[0067] In order to allow as much sand and gravel as possible to enter the spiral pushing device 28, the filter plate 30 and the bottom surface of the sedimentation box 3 are inclined, and the sedimentation port is set on the low side of the bottom surface of the sedimentation box 3. The sand and gravel follow the filter plate 30 and the bottom surface of the sedimentation box 3 to reach the low side, that is, to the sedimentation port, which speeds up the speed of the sand and gravel reaching the sedimentation port. The sand and gravel are not easy to accumulate on the bottom surface of the sedimentation box 3, thereby improving the sand and gravel discharge rate.

[0068] Based on the above specific embodiments, it also includes:

[0069] A sewage level meter 20 installed on the sedimentation box 3 for detecting the real-time height of sewage in the sedimentation box 3;

[0070] A clean water level meter 19 installed on the clean water tank 5 to detect the real-time height of the clean water in the clean water tank 5;

[0071] An operating control box 18 is connected to the sewage level meter 20 and the clean water level meter 19, and is used to control the sewage pumping device to stop pumping water when the sewage reaches the limit height of the sewage level meter 20; and to control the clean water tank 5 to stop taking in water when the clean water reaches the limit height of the clean water level meter 19.

[0072] In a specific embodiment, the dredging and sewage suction and purification vehicle is equipped with an external water supply connector 15, which is connected to a municipal fire hydrant to facilitate the supply of clean water to the clean water tank 5. A clean water level gauge 19 is installed on the clean water tank 5 to detect the real-time height of the clean water in the clean water tank 5. The operation control box 18 is connected to the sewage level gauge 20, and there is a preset limit height in the operation control box 18. The operation control box 18 compares the limit height with the real-time height. When the clean water reaches the limit height of the clean water level gauge 19, it means that the water in the clean water tank 5 has reached the limit height, the clean water tank 5 is full, and the clean water tank 5 is controlled to stop taking in water.

[0073] The sewage level meter 20 is installed on the sedimentation box 3, and the sewage level meter 20 detects the real-time height of the sewage in the sedimentation box 3. The operation control box 18 and the sewage level meter 20 are connected, and the sewage level meter 20 sends the real-time height of the sewage in the sedimentation box 3 to the operation control box 18. The operation control box 18 has a preset limit height of the sedimentation box 3, and compares the limit height with the real-time height. When the sewage reaches the limit height of the sewage level meter 20, it means that the sedimentation box 3 is full of water, and the sewage pumping device is controlled to stop pumping water to prevent sewage overflow.

[0074] In the above embodiment, an operation control box 18 is configured to control the operation of the valve and the pump body through the operation control box 18 to achieve automatic control and reduce the work pressure of the operator.

[0075] Based on the above specific embodiments, it also includes:

[0076] A sedimentation wastewater flow rate detector for detecting the flow rate of the wastewater entering the sedimentation box 3;

[0077] A flocculation wastewater flow rate detector for detecting the flow rate of the wastewater entering the flocculation tank 4, a sedimentation wastewater flow rate detector and a flocculation wastewater flow rate detector are all connected to the operation control box 18;

[0078] A flow rate regulating device connected to the operation control box 18,

[0079] The flow rate regulating device is used to control the flow rate of sewage inlet into the flocculation box 4 to be lower than the flow rate of sewage inlet into the sedimentation box 3 when the sewage level meter 20 detects that the real-time height of sewage in the sedimentation box 3 is lower than the low-level height; and to control the flow rate of sewage inlet into the flocculation box 4 to be higher than the flow rate of sewage inlet into the sedimentation box 3 when the real-time height of sewage in the sedimentation box 3 is detected to be higher than the high-level height.

[0080] In a specific embodiment, a sedimentation wastewater flow rate detector is provided at the water inlet of the sedimentation box 3 to detect the flow rate of the wastewater entering the sedimentation box 3 ; a flocculation wastewater flow rate detector is provided at the water inlet of the flocculation box 4 to detect the flow rate of the wastewater entering the flocculation box 4 .

[0081] The sedimentation wastewater flow rate detector and the flocculation wastewater flow rate detector send the detection results to the operation control box 18, which is provided with a low level height and a high level height. The real-time height of the wastewater in the sedimentation box 3 detected by the wastewater level meter 20 is compared with the low level height and the high level height.

[0082] When the sewage level meter 20 detects that the real-time height of the sewage in the sedimentation tank 3 is less than the low-level height, the operation control box 18 controls the flow rate of the sewage entering the flocculation tank 4 to be less than the flow rate of the sewage entering the sedimentation tank 3 by adjusting the flow rate regulating device; when the sewage level meter 20 detects that the real-time height of the sewage in the sedimentation tank 3 is greater than the high-level height, the operation control box 18 controls the flow rate of the sewage entering the flocculation tank 4 to be greater than the flow rate of the sewage entering the sedimentation tank 3 by adjusting the flow rate regulating device.

[0083] In the above embodiment, the water inlet flow rate of the sedimentation box 3 or the water inlet flow rate of the flocculation box 4 is adjusted by the flow rate regulating device. When the sewage in the sedimentation box 3 is at a high level, the water inlet flow rate of the flocculation box 4 is increased and / or the water inlet flow rate of the sedimentation box 3 is decreased, so that the sewage in the sedimentation box 3 can quickly flow into the flocculation box 4, thereby preventing the sewage in the sedimentation box 3 from continuing to increase; when the sewage in the sedimentation box 3 is at a low level, the water inlet flow rate of the sedimentation box 3 is increased and / or the water inlet flow rate of the flocculation box 4 is decreased, thereby making the sewage in the sedimentation box 3 flow slowly into the flocculation box 4.

[0084] The flow rate regulating device may include: an opening regulating mechanism for regulating the opening sizes of the inlet of the sedimentation box 3 and the inlet of the flocculation box 4 .

[0085] In a preferred embodiment, the opening adjustment mechanism may include:

[0086] A first regulating baffle and a second regulating baffle are respectively arranged at the inlet of the sedimentation box 3 and the inlet of the flocculation box 4, and the regulating baffles are rotatably connected to the inner wall of the inlet;

[0087] A rotating component connected to the two adjusting baffles and used to control the adjusting baffles to rotate to set angles respectively.

[0088] In the above embodiment, the first regulating baffle and the second regulating baffle cooperate to control the ratio of the water inlet flow rate of the sedimentation box 3 and the water inlet flow rate of the flocculation box 4. The water inlet flow rate is controlled by controlling the angle between the regulating baffle and the inlet, which is convenient to operate and easy to control.

[0089] Optionally, the rotating component includes:

[0090] An angle sensor for detecting the current angle between the second adjustment baffle and the corresponding inlet center line;

[0091] A calculation unit connected to the angle sensor, used to calculate the rotation angles of the two adjusting baffles according to the water inlet flow rate of the sedimentation box 3, the water inlet flow rate of the flocculation box 4 and the current angles between the two adjusting baffles and the corresponding inlet center line;

[0092] A rotation execution unit connected to the calculation unit and used for controlling the rotation of the two adjustment baffles according to the rotation angle calculated by the calculation unit.

[0093] In the above embodiment, the baffle is controlled to rotate directly from the current angle to the real-time angle, and the baffle does not need to be reset to the initial position, so the control is simpler and faster, and the inlet size can be adjusted accurately.

[0094] Of course, the flow rate regulating device can also adjust the water flow rate of the sedimentation box 3 and the water flow rate of the flocculation box 4 by controlling the speed of the pump, and can also be a control valve connected to the slurry pump 10, the sewage vacuum pump 14, and the water pump 26.

[0095] When the sewage in the sedimentation box 3 is at a high level, the control valve of the flocculation box 4 is increased and / or the control valve of the sedimentation box 3 is decreased, so that the sewage in the sedimentation box 3 can quickly flow into the flocculation box 4 to avoid further increase of the sewage in the sedimentation box 3; when the sewage in the sedimentation box 3 is at a low level, the control valve of the sedimentation box 3 is increased and / or the control valve of the flocculation box 4 is decreased, so that the sewage in the sedimentation box 3 can slowly flow into the flocculation box 4.

[0096] Based on the above specific embodiments, the drug mixing tank 8 includes at least two multi-stage drug mixing tanks 8 connected in sequence, and the tank volume of the multi-stage drug mixing tank 8 on the side away from the flocculation tank 4 is larger than the tank volume on the side close to the flocculation tank 4.

The clean water and chemicals undergo complete three-stage mixing, realizing a three-stage mixing cycle of PAM cations and clean water, extending the mixing time of chemicals and clean water, and realizing full and uniform mixing of the chemicals.

[0101] In a specific embodiment, the dredging and sewage suction and purification vehicle is equipped with a large-flow high-pressure plunger pump 7, which is installed behind the cab of the chassis 1 and driven by the full-power power take-off of the chassis 1 to achieve high-pressure and large-flow dredging of municipal pipelines. The high-pressure plunger pump 7 draws clean water from the clean water tank 5, and after being driven by the engine, discharges high-pressure clean water, and dredges the sludge in the municipal pipeline by high-pressure impact through the dredging hose drum 9. In addition, the dredging hose drum 9 is relatively long, so that long-distance dredging of municipal pipelines can be achieved.

[0102] The water inlet of the high-pressure cleaning machine 17 is connected to the clean water tank 5. The high-pressure cleaning machine 17 is equivalent to a high-pressure spray gun. After the work is completed, the high-pressure cleaning machine 17 can clean the ground hygiene of the working section and the hygiene of each component of the equipment itself to keep the equipment and the environment clean.
