Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a mobile water treatment device. Background Technology

[0002] With rapid industrialization and urbanization, water pollution has become increasingly serious, making water purification and reuse particularly important. Especially in remote areas or emergency situations, rapidly mobile water treatment units are crucial. Traditional fixed water treatment facilities cannot meet the demands for rapid deployment and mobility; therefore, a mobile water treatment unit that is easy to transport, install, and use is needed.

[0003] The existing equipment has the following disadvantages: When treating water, the existing equipment needs to squeeze the impurities in the sewage into mud blocks for discharge. When the mud blocks are discharged from the mobile treatment equipment, they stick to the unloading plate, which affects the discharge of sludge. The traditional cleaning method is to manually remove the mud blocks from the unloading plate with shovels, which not only increases labor costs but also has low cleaning efficiency.

[0004] Therefore, this application proposes a mobile water treatment device to solve the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a mobile water treatment device to solve the problems of increased labor costs and low efficiency in cleaning sludge.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mobile water treatment device, comprising a transport vehicle, a water purification device installed inside the transport vehicle, a sludge press installed inside the transport vehicle and connected to the water purification device for compressing flocculent matter in the water purification device into sludge, and a sludge discharge port installed at the upper end of the sludge press for discharging sludge, and further comprising:

[0007] A cleaning unit is located below the discharge port and is used to guide and clear the discharged mud.

[0008] The cleaning unit includes:

[0009] A mud discharge plate is adjustablely positioned below the discharge port to guide the mud blocks discharged from the discharge port.

[0010] A mud scraper is adjustablely mounted on the mud discharge plate and is used to clean up the mud clumps accumulated on the mud discharge plate.

[0011] The mud discharge plate is adjustable and positioned below the discharge port via an adjustment device;

[0012] The adjusting device includes a fixed plate fixed on the transport vehicle and symmetrically arranged about the unloading plate, a connecting plate fixed on both sides of the upper end of the unloading plate, a mounting block fixed at the lower end of the fixed plate, a hydraulic rod rotatably connected to the mounting block, and a connecting block disposed at the power output end of the hydraulic rod and connected to the unloading plate. A fixed rod is fixed on the fixed plate, and the connecting plate is rotatably sleeved on the fixed rod.

[0013] The sludge scraping device is adjustablely mounted on the sludge discharge plate via a power unit, and the sludge discharge plate is provided with a side plate for mounting the power unit.

[0014] The power unit includes a motor mounted on the side plate, a rotating shaft mounted on the power output end of the motor, and a cleaning rod mounted on the side of the rotating shaft away from the motor and passing through the side plate in a square configuration. The cleaning rod is connected to the sludge scraping device, and the side plate has a limiting groove at the position corresponding to the cleaning rod for the cleaning rod to move.

[0015] The rotating shaft is connected to the side plate via a transmission component.

[0016] The transmission component includes a second rack fixed to the side plate and arranged parallel to the side plate, and a first gear sleeved on the rotating shaft. The second rack is provided with a mounting plate for mounting the motor. A slider that is slidably connected to the second rack is provided on the side of the mounting plate close to the second rack. The second rack is provided with a groove for the slider to move. The first gear is meshed with the second rack.

[0017] The sludge scraping device includes a collar sleeved in the middle of the cleaning rod, a fixed shaft disposed on the collar near the sludge unloading plate, and a scraper adjustablely disposed on the fixed shaft for cleaning sludge on the sludge unloading plate, wherein the scraper abuts against the sludge unloading plate.

[0018] The scraping component includes a first rotating rod sleeved on the fixed shaft, a second rotating rod sleeved on the fixed shaft and symmetrically arranged about the first rotating rod, and a scraper fixed to the side of the first rotating rod and the second rotating rod away from the fixed shaft. An elastic element is provided between the two scrapers.

[0019] The collar has a second gear on one side, and a first rack is provided at the bottom of the side plate at the position corresponding to the second gear. The first rack meshes with the second gear.

[0020] The scraper has two sides that abut against the side plate, and the connection between the scrapers is arc-shaped.

[0021] The lateral dimension of the mud discharge plate gradually decreases downward.

[0022] The water purification equipment includes a water tank fixed inside the transport vehicle, a multi-stage purification device installed inside the water tank, and a water outlet installed on one side of the water tank and connected to the sludge press. The upper end of the transport vehicle is provided with a water inlet pipe for supplying water to the water tank.

[0023] The multi-stage purification equipment includes a first treatment box, a second treatment box, a third treatment box and a fourth treatment box. The first treatment box is equipped with a filter frame located below the water inlet pipe. The first treatment box, the second treatment box and the third treatment box are all equipped with water pumps.

[0024] The third and fourth processing boxes are equipped with mixing devices.

[0025] Both the third and fourth treatment boxes are equipped with dosing tanks on their sides for adding purification agents into the third and fourth treatment boxes.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. This invention involves driving a transport vehicle to the location where water needs to be treated, then using a pumping device to pump the wastewater into a water purification system for treatment. The purified wastewater is then discharged into a mud press to separate the mud and water. The extruded mud blocks are discharged from the outlet and fall onto a mud unloading plate. A mud scraping device then automatically cleans the mud blocks adhering to the mud unloading plate, reducing the amount of sludge adhering to the mud unloading plate and thus improving the efficiency of subsequent sludge discharge.

[0028] 2. The square shape of the cleaning rod in this invention allows it to slide without rotating within the limiting groove. This enables the cleaning rod to drive the scraper to move horizontally within the unloading plate, cleaning impurities from the unloading plate and reducing the blockage caused by mud accumulation, which affects the discharge efficiency. The collar rotates and is fitted onto the cleaning rod. When the cleaning rod moves the collar to the position of the first rack, the second gear on the collar meshes with the first rack, causing the collar to rotate clockwise on the cleaning rod. The mud falling onto the scraper can then slide off and be discharged. Attached Figure Description

[0042] 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.

[0043] Please see Figure 1-12 The present invention provides a technical solution: a mobile water treatment device, comprising a transport vehicle 1, a water purification device 2 installed inside the transport vehicle 1, a sludge press 3 installed inside the transport vehicle 1 and connected to the water purification device 2 for compressing flocculent matter in the water purification device 2 into sludge, and a discharge port 31 installed at the upper end of the sludge press 3 for discharging sludge, and further comprising:

[0044] The cleaning unit 4 is located below the discharge port 31 and is used to guide and clear the discharged mud.

[0045] Cleaning unit 4 includes:

[0046] The mud discharge plate 41 is adjustablely positioned below the discharge port 31 to guide the mud blocks discharged from the discharge port 31.

[0047] The mud scraper 47 is adjustablely mounted on the mud discharge plate 41 and is used to clean the mud clumps accumulated on the mud discharge plate 41.

[0048] It should be noted that during operation, the transport vehicle 1 is driven to the location where the water source needs to be treated, and then the sewage is pumped into the water purification equipment 2 through the pumping device for treatment. The purified sewage is then discharged into the mud press 3 to separate the mud and water. The extruded mud blocks are discharged from the discharge port 31 and then fall onto the mud unloading plate 41. The mud blocks adhering to the mud unloading plate 41 are then automatically cleaned by the mud scraping device 47, which can reduce the amount of sludge adhering to the mud unloading plate 41 and affect the efficiency of subsequent sludge discharge.

[0049] In one embodiment, the mud discharge plate 41 is adjustablely positioned below the discharge port 31 via an adjusting device 42;

[0050] The adjusting device 42 includes a fixed plate 43 fixed on the transport vehicle 1 and symmetrically arranged about the unloading plate 41, a connecting plate 411 fixed on both sides of the upper end of the unloading plate 41, a mounting block 421 fixed at the lower end of the fixed plate 43, a hydraulic rod 422 rotatably connected to the mounting block 421, and a connecting block 423 set at the power output end of the hydraulic rod 422 and connected to the unloading plate 41. A fixed rod 431 is fixed on the fixed plate 43, and the connecting plate 411 is rotatably sleeved on the fixed rod 431.

[0051] This design is for reference. Figure 1-6 After the sewage treatment is completed, the rear door of the transport vehicle 1 is opened, and then the hydraulic rod 422 is activated. The hydraulic rod 422 pushes the unloading plate 41 to rotate along the fixed rod 431, so that the unloading plate 41 extends out of the inside of the transport vehicle 1, and then the mud is discharged from the transport vehicle 1 along the unloading plate 41.

[0052] In one embodiment, the sludge scraping device 47 is adjustablely mounted on the sludge discharge plate 41 via a power device 44, and the sludge discharge plate 41 is provided with a side plate 412 for mounting the power device 44.

[0053] The power unit 44 includes a motor 443 mounted on the side plate 412, a rotating shaft 444 mounted on the power output end of the motor 443, and a cleaning rod 46 mounted on the side of the rotating shaft 444 away from the motor 443 and passing through the side plate 412 in a square configuration. The cleaning rod 46 is connected to the sludge scraping device 47. A limiting groove 4121 for the cleaning rod 46 to move is provided at the corresponding position of the cleaning rod 46 on the side plate 412.

[0054] The rotating shaft 444 is connected to the side plate 412 via a transmission component.

[0055] This design is for reference. Figure 4-5 ,as well as Figure 12 When mud clumps fall onto the unloading plate 41, the silt slides off the unloading plate 41. Because the mud clumps are sticky, they will stick to the unloading plate 41, which will affect the subsequent silt discharge. At this time, the power motor 443 is started to drive the rotating shaft 444 to rotate. Then the rotating shaft 444 is connected to the transmission component on the side plate 412. Under the action of the transmission component, the rotating shaft 444 moves up and down on the unloading plate 41. Then the cleaning rod 46 moves down inside the limiting groove 4121 on the side plate 412. Then the cleaning rod 46 drives the scraping device 47 to move inside the unloading plate 41 to clean the silt stuck to the unloading plate 41.

[0056] In one embodiment, the transmission component includes a second rack 45 fixed on and parallel to the side plate 412 and a first gear 445 sleeved on the rotating shaft 444. The second rack 45 is provided with a mounting plate 441 for mounting a motor 443. A slider 442 that is slidably connected to the second rack 45 is provided on the side of the mounting plate 441 close to the second rack 45. The second rack 45 is provided with a groove 451 for the slider 442 to move. The first gear 445 is meshed with the second rack 45.

[0057] This design is for reference. Figure 5 ,as well as Figure 9The rotating shaft 444 is rotatably inserted through the middle of the cleaning rod 46 and drives the first gear 445 to rotate. Then, the first gear 445 meshes with the second rack 45, driving the first gear 445 to travel along the path of the second rack 45. The mounting plate 441 can fix the motor 443. The slider 442 travels in the slide groove 451, which can improve the stability of the motor 443 installation. The square shape of the cleaning rod 46 allows it to slide without rotating inside the limiting groove 4121. This allows the cleaning rod 46 to drive the sludge scraping device 47 to move horizontally inside the mud discharge plate 41, cleaning the impurities on the mud discharge plate 41 and reducing the phenomenon of mud blockage on the mud discharge plate 41 caused by the accumulation of mud, which affects the mud discharge efficiency.

[0058] In one embodiment, the sludge scraping device 47 includes a collar 471 sleeved in the middle of the cleaning rod 46, a fixed shaft 472 disposed on the side of the collar 471 near the sludge discharge plate 41, and a scraping member adjustablely disposed on the fixed shaft 472 for cleaning the mud on the sludge discharge plate 41, the scraping member abutting against the sludge discharge plate 41.

[0059] This design is for reference. Figure 7-9 The cleaning rod 46 drives the fixed shaft 472 to move down, causing the scraper on the fixed shaft 472 to slide off the mud discharge plate 41 and scrape off the mud stuck to the mud discharge plate 41 by friction.

[0060] In one embodiment, the scraping component includes a first rotating rod 473 sleeved on a fixed shaft 472, a second rotating rod 474 sleeved on the fixed shaft 472 and symmetrically arranged about the first rotating rod 473, and a scraper 475 fixed on the side of the first rotating rod 473 and the second rotating rod 474 away from the fixed shaft 472, with an elastic element 476 provided between the two scrapers 475.

[0061] This design is for reference. Figure 7-9 ,as well as Figure 11 The first rotating rod 473 and the second rotating rod 474 can rotate along the fixed shaft 472, thereby adjusting the lateral distance of the scraper 475 according to the distance between the side plates 412, so as to meet the use of different sizes of mud discharge plates 41 and improve the practicality of the whole device.

[0062] In one embodiment, a second gear 4711 is provided on one side of the collar 471, and a first rack 4122 is provided at the bottom of the side plate 412 at the position corresponding to the second gear 4711. The first rack 4122 is meshed with the second gear 4711.

[0063] This design is for reference. Figure 10The collar 471 is rotatably mounted on the cleaning rod 46. When the cleaning rod 46 moves the collar 471 to the position of the first rack 4122, the second gear 4711 on the collar 471 meshes with the first rack 4122, causing the collar 471 to rotate clockwise on the cleaning rod 46. The mud that falls on the scraper 475 can then slide off and be discharged. When the scraper 475 moves to the lowest point, the motor 443 drives the cleaning rod 46 to move upward. Then the second gear 4711 meshes with the first rack 4122, causing the scraper 475 to reset and move upward to the upper part of the mud discharge plate 41.

[0064] In one embodiment, the two sides of the scraper 475 abut against the side plate 412, and the connection between the scrapers 475 is arc-shaped.

[0065] The lateral dimension of the mud discharge plate 41 gradually decreases downwards.

[0066] This design is for reference. Figure 4-6 The lower end of the mud discharge plate 41 gradually decreases in size, which can gather the material and facilitate the collection and processing of falling mud lumps. The arc-shaped design on both sides of the scraper 475 can reduce the friction between the scraper 475 and the side plate 412, making it easier for the scraper 475 to move inside the side plate 412. When the scraper 475 contacts the side plate 412, it will be squeezed by the side plate 412, causing the two scrapers 475 to converge towards the side closer to the fixed shaft 472, so that the scraper 475 can be used to clean mud discharge plates 41 of different shapes.

[0067] In one embodiment, the water purification device 2 includes a water tank 21 fixed inside the transport vehicle 1, a multi-stage purification device installed inside the water tank 21, and a water outlet 26 installed on one side of the water tank 21 and connected to the sludge press 3. The upper end of the transport vehicle 1 is provided with a water inlet pipe 11 for supplying water to the inside of the water tank 21.

[0068] This design is for reference. Figure 3 ,as well as Figure 6 Wastewater enters the interior of water tank 21 through inlet pipe 11, and then is purified by multi-stage purification equipment inside water tank 21. The purified water then flows into the interior of sludge press 3 from outlet 26, separating the purified water from impurities and sludge.

[0069] In one embodiment, the multi-stage purification device includes a first treatment box 211, a second treatment box 212, a third treatment box 213, and a fourth treatment box 214, all of which are existing technologies, so their specific structures will not be described in detail here. A filter frame 22 is provided in the first treatment box 211 below the water inlet pipe 11, and a water pump 23 is provided inside the first treatment box 211, the second treatment box 212, and the third treatment box 213.

[0070] The third processing box 213 and the fourth processing box 214 are equipped with a mixing device 24. The mixing device 24 is existing technology, so its specific structure will not be described in detail here.

[0071] Both the third treatment box 213 and the fourth treatment box 214 are provided with dosing tanks 25 on their sides for adding purification agents into the third treatment box 213 and the fourth treatment box 214. The dosing tanks 25 are existing technology, so their specific structure will not be described in detail here.

[0072] This design is for reference. Figure 6 The wastewater undergoes initial purification through the filter frame 22 inside the first treatment tank 211. Then, the wastewater is pumped by the water pump 23 into the second treatment tank 212 for secondary disinfection. After that, it is added to the third treatment tank 213, where the dosing tank 25 adds flocculant. The wastewater then passes through the fourth treatment tank 214, where a coagulant aid is added for coagulation and sedimentation. Finally, the wastewater is fed from the outlet 26 into the sludge press 3 for solid-liquid separation, and the sludge solids are discharged from the discharge port 31.

[0073] Furthermore, if the embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relation to the specification. The significance or implied number of the indicated technical features is not specified. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
