Description

Technical Field

[0001] This application relates to the field of wastewater treatment, and more specifically, to an emergency response vehicle suitable for decentralized rural wastewater treatment facilities. Background Technology

[0002] Rural domestic sewage mainly originates from feces and flushing water, bathing wastewater, and kitchen wastewater during residents' daily lives. Since feces contain a large number of pathogens, rural domestic sewage generally requires sterilization treatment.

[0003] Due to the small rural population, low water consumption standards, and small-scale sewage treatment, the construction and operation costs of projects are too high. Furthermore, the selection of sewage treatment processes and technologies is constrained by the local social and economic development level or other human factors, making it unsuitable to invest in large-scale pipeline networks for large-scale purification treatment.

[0004] Agricultural wastewater contains a large amount of household debris. After collection, it cannot be treated directly. The debris and wastewater need to be separated before the wastewater is professionally treated. Moreover, the collection process is prone to blockage, which affects the collection efficiency. Summary of the Invention

[0005] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an emergency treatment vehicle suitable for decentralized rural sewage treatment facilities. This vehicle, utilizing engineering vehicles, can flexibly treat decentralized rural sewage and separate wet and dry wastewater, minimizing debris in the liquid treatment tank and ensuring sufficient sewage capacity. Simultaneously, the engineering vehicle can pre-treat the sewage before transporting it to specialized sites for further treatment, avoiding large-scale pipeline investment and reducing costs.

[0006] This application proposes an emergency treatment vehicle suitable for decentralized rural sewage treatment facilities, comprising an engineering vehicle and a liquid treatment tank. The liquid treatment tank is fixedly connected to the engineering vehicle, and a first infusion pump is fixedly connected to the liquid treatment tank.

At the same time, the engineering vehicle can pre-treat the sewage and then transport it to a professional site for fine treatment, avoiding large-scale pipeline investment and reducing costs.

[0012] In addition, the emergency response vehicle for decentralized rural sewage treatment facilities according to the embodiments of this application also has the following additional technical features:

[0013] In some specific embodiments of this application, one end of the working chamber is fixedly connected to a drain chamber, and a drain port is provided at the bottom of the drain chamber.

[0014] In some specific embodiments of this application, bearing seats are fixedly connected to the two end faces of the working chamber and the drain chamber that are far apart from each other.

[0015] In some specific embodiments of this application, a bracket is fixedly connected to the bottom of the drainage tank, and the bracket is fixedly connected to the engineering vehicle.

[0016] In some specific embodiments of this application, the output end of the sludge pump is connected to the conveying pipe.

[0017] In some embodiments of this application, the bearing housing is described.

[0018] In some embodiments of this application, the anti-clogging assembly includes a drive motor, a transmission belt, a transmission shaft sleeve, a second filter screen, a third auger, and a wet-dry separation chamber. The drive motor is fixedly connected to the engineering vehicle. One end of the transmission belt is drivenly connected to the output end of the drive motor, and the other end of the transmission belt is drivenly connected to the transmission shaft sleeve. The transmission shaft sleeve is rotatably sleeved on the feed pipe and fixedly inserted into the bearing seat on the drain chamber. The transmission shaft sleeve extends into the working chamber. One end of the second filter screen is fixedly connected to the transmission shaft sleeve and rotatably sleeved on the adapter pipe. The third auger is fixedly connected to the inner wall of the second filter screen and is adapted to the first filter cartridge. The wet-dry separation chamber is fixedly connected to the second filter screen and rotatably connected to the working chamber.

[0019] In some embodiments of this application, the second filter screen is sleeved on the first filter cartridge, and the dry-wet separation chamber is sleeved on the second filter screen.

[0020] In some embodiments of this application, the dry-wet separation chamber is provided with a plurality of liquid outlets at the end away from the feed pipe.

[0021] In some embodiments of this application, a sewage discharge mechanism is provided in the drainage chamber, and the sewage discharge mechanism is fixedly connected to the dry and wet separation chamber.

[0022] In some embodiments of this application, the sewage discharge mechanism includes a driven disc and a scraper, the driven disc being fixedly connected to the dry and wet separation chamber, and the scraper being fixedly connected to the driven disc.

[0023] In some embodiments of this application, the scrapers are arranged in a circumferential array on the driven disc, and the scrapers are in contact with the inner wall of the drainage chamber.

[0024] In some embodiments of this application, the separation assembly is provided with an auxiliary mechanism, which includes a second infusion pump and a nozzle. The second infusion pump is fixed to the engineering vehicle, and the output end of the second infusion pump is connected to the connecting pipe. The nozzle is fixedly connected to the second drive shaft, and the nozzle is designed with a spiral along the axial direction of the second drive shaft.

[0025] In some embodiments of this application, the first drive shaft is a hollow design with openings at both ends, and a through hole is provided on one end sidewall of the first drive shaft inside the connecting pipe.

[0026] In some embodiments of this application, the second drive shaft is a hollow design with one end closed, and the second drive shaft is connected to the first drive shaft.

[0027] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application.

[0028] During use, the drainage tank of this emergency treatment vehicle, which is suitable for decentralized rural sewage treatment facilities, will inevitably become clogged over time. If this clog is not addressed, it will easily lead to a decrease in the treatment efficiency of the vehicle for rural sewage.

[0029] During the use of this emergency treatment vehicle suitable for decentralized rural sewage treatment facilities, the dry and wet separation chamber rotates under the action of the drive motor, while the drainage chamber is fixed to the working chamber. Therefore, the scraper and driven plate rotate synchronously with the dry and wet separation chamber. Since the scraper is in contact with the inner wall of the drainage chamber, the rotating scraper continuously scrapes the inner wall of the drainage chamber, preventing the drainage chamber from being clogged by scale due to small amounts of debris contained in the sewage that have not been treated for a long time.

[0030] This emergency treatment vehicle, applicable to decentralized rural sewage treatment facilities, inevitably leaves residual dirt in the second auger, first filter cartridge, second filter cartridge, third auger, and dry-wet separation chamber after treating the sewage. If this dirt is not treated in time, it can easily cause scale buildup in the first filter cartridge, second filter cartridge, and dry-wet separation chamber, making it impossible for the equipment to complete dry-wet separation the next time it is used.

[0031] After using the emergency treatment vehicle suitable for decentralized rural sewage treatment facilities, the second infusion pump is started to supply water from the outside to the first and second drive shafts, which is then sprayed out by the nozzles. During this process, the delivery motor can be started to drive the second drive shaft and the second auger to rotate. The drive motor drives the second filter cartridge, the third auger, and the dry-wet separation chamber to rotate, which in turn causes the nozzles to rotate with the second drive shaft, causing the nozzles to rotate and spray water. At the same time, the rotation of the second and third augers can scrape off the dirt washed down by the water flow from the first filter cartridge. In addition, the rotating second filter cartridge and the dry-wet separation chamber can also wash the dirt off themselves. Finally, the sewage containing dirt after rinsing can be pumped out by the first infusion pump and discharged to the outside. The output end of the first infusion pump needs to be removed from the liquid treatment tank. This design avoids the scale formation caused by residual dirt, which is suitable for decentralized rural sewage treatment facilities. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] like Figures 1-11 As shown in the embodiment of this application, an emergency treatment vehicle suitable for decentralized rural sewage treatment facilities includes an engineering vehicle 1 and a liquid treatment tank 2. The liquid treatment tank 2 is fixed to the engineering vehicle 1 and is used for pre-treatment of sewage. It should be noted that the top of the liquid treatment tank 2 is provided with a chemical injection port for adding relevant chemicals to the liquid treatment tank 2 for preliminary treatment of the sewage. The bottom of the liquid treatment tank 2 is provided with a liquid outlet for discharging the pre-treated sewage. In this embodiment, the pre-treated sewage in the liquid treatment tank 2 can be discharged to a dedicated sewage treatment site for further treatment. The system includes a liquid treatment tank 2 with a first infusion pump 21 fixedly connected to it. The output end of the first infusion pump 21 is connected to the liquid treatment tank 2. Multiple baffles 22 are equidistantly arranged inside the liquid treatment tank 2. The top and bottom sides of the baffles 22 are suspended to prevent the sewage in the liquid treatment tank 2 from shaking excessively during the operation of the emergency treatment vehicle suitable for decentralized rural sewage treatment facilities. This avoids the vehicle from generating a large inertia due to the shaking of the sewage in the liquid treatment tank 2 during operation, which could lead to a safety accident. The system also includes a dry-wet separation mechanism 300, a sewage discharge mechanism 400, and an auxiliary mechanism 500.

[0047] The input end of the first infusion pump 21 is connected to the dry-wet separation mechanism 300.

[0048] Furthermore, the dry-wet separation mechanism 300 includes a working chamber 310, a sewage pump 320, a separation component 330, and an anti-clogging component 340. The working chamber 310 is fixed to the engineering vehicle 1, the sewage pump 320 is fixed to the engineering vehicle 1, and the output end of the sewage pump 320 is connected to the separation component 330. The input end of the sewage pump 320 is connected to a sewage pumping pipe for pumping rural sewage.

[0049] The separation component 330 includes a conveyor motor 331, a first drive shaft 332, a first auger 333, a connecting pipe 334, a conveying pipe 335, a second drive shaft 336, a second auger 337, a first filter cartridge 338, and a transfer pipe 339. The conveyor motor 331 is fixedly connected to the engineering vehicle 1. The first drive shaft 332 is keyed to the output end of the conveyor motor 331, allowing the first drive shaft 332 to rotate under the drive of the conveyor motor 331. The first auger 333 is fixedly connected to the periphery of the first drive shaft 332. This allows the first auger 333 and the first drive shaft 332 to rotate synchronously. A connecting pipe 334 is sleeved on the first drive shaft 332, with one end of the connecting pipe 334 fixedly connected to the conveying motor 331 and the other end fixedly connected to the conveying pipe 335. The connecting pipe 334 and the conveying pipe 335 are not connected to each other to prevent sewage and debris in the conveying pipe 335 from flowing back into the connecting pipe 334. The conveying pipe 335 extends into the working chamber 310, and an opening is provided at the bottom of the end of the conveying pipe 335 located within the working chamber 310. This allows sewage and waste to be discharged through the conveying pipe 335 under the transport of the first auger 333. The conveying pipe 335 is fixedly connected to the working chamber 310. It should be noted that the conveying pipe 335 and the working chamber 310 are sealed to prevent sewage leakage. The second drive shaft 336 is drivenly connected to the end of the first drive shaft 332 away from the conveying motor 331. The second drive shaft 336 and the conveying pipe 335 are rotatably connected, allowing the second drive shaft 336 to rotate normally with the first drive shaft 332. The second auger 337 is fixed. The second screw conveyor 337 is attached to the circumference of the second drive shaft 336, so that the second screw conveyor 337 and the second drive shaft 336 rotate synchronously. It should be noted that the spiral direction of the second screw conveyor 337 and the first screw conveyor 333 is the same. The first filter cartridge 338 is fixedly connected to the working chamber 310. The first filter cartridge 338 and the conveying pipe 335 are in a sealed rotational fit. The transfer pipe 339 is fixedly connected to the first filter cartridge 338. The transfer pipe 339 is fixedly connected to the working chamber 310. It should be noted that the transfer pipe 339 is used to discharge the dirt contained in the sewage into the working chamber 310.

[0050] It should be noted that the bottom opening of the feed pipe 335 is located inside the first filter cartridge 338.

[0051] The anti-blocking component 340 is installed on the working chamber 310. The anti-blocking component 340 and the separation component 330 work together to clear the blockage of the separation component 330.

[0052] The following description, with reference to the accompanying drawings, describes the use of an emergency response vehicle suitable for decentralized rural wastewater treatment facilities according to an embodiment of this application:

[0053] When performing emergency treatment of scattered rural sewage, the sewage pump 320 is started to extract the rural sewage, which is then transported through the output end of the sewage pump 320 into the conveying pipe 335. Simultaneously, the conveying motor 331 is started, driving the first drive shaft 332, the first auger 333, the second drive shaft 336, and the second auger 337 to rotate synchronously. The first auger 333 transports the extracted sewage and its contained impurities through the conveying pipe 335 into the first filter cartridge 338. During the rotation of the second auger 337, the sewage is... The wastewater seeps out of the first filter cartridge 338, while the waste is conveyed by the second auger 337 to the transfer pipe 339 and finally discharged from the working chamber 310. The wastewater in the working chamber 310 is finally collected by the anti-clogging component 340 and directed to the input end of the first infusion pump 21. The first infusion pump 21 then delivers the wastewater to the liquid treatment tank 2. The staff then adds chemicals to the liquid treatment tank 2 to perform preliminary treatment on the wastewater and stores it. After the tank is full, it is transported by the engineering vehicle 1 to a special wastewater treatment site for further fine treatment.

[0054] In addition, the emergency response vehicle for decentralized rural sewage treatment facilities according to the embodiments of this application also has the following additional technical features:

[0055] It should be noted that one end of the working chamber 310 is fixedly connected to the drain chamber 311, and the drain chamber 311 has a drain port at the bottom. The input end of the first infusion pump 21 is connected to this drain port, so as to facilitate the pumping of the sewage inside to the liquid treatment tank 2.

[0056] Among them, bearing seats 312 are fixedly connected to the two end faces of the working chamber 310 and the drain chamber 311 that are far apart from each other, and the bearing seats 312 are respectively sealed to the working chamber 310 and the drain chamber 311.

[0057] It should be noted that a bracket 313 is fixedly connected to the bottom of the drainage tank 311, and the bracket 313 is fixedly connected to the engineering vehicle 1.

[0058] Furthermore, the output end of the sewage pump 320 is connected to the conveying pipe 335, which facilitates the conveying of the pumped sewage and waste to the conveying pipe 335.

[0059] Furthermore, the second auger 337 is compatible with the first filter cartridge 338. It should be noted that the second auger 337 and the first filter cartridge 338 are in contact, so that the second auger 337 can clean the dirt in the first filter cartridge 338 as much as possible during the rotation.

[0060] Specifically, the adapter pipe 339 is fixedly inserted into the bearing seat 312 on the drain chamber 311. It should be noted that the adapter pipe 339 and the bearing seat 312 are sealed together.

[0061] Furthermore, the anti-clogging component 340 includes a drive motor 341, a transmission belt 342, a transmission sleeve 343, a second filter cartridge 344, a third auger 345, and a dry-wet separation chamber 346. The drive motor 341 is fixedly connected to the engineering vehicle 1. One end of the transmission belt 342 is connected to the output end of the drive motor 341, and the other end of the transmission belt 342 is connected to the transmission sleeve 343. The transmission sleeve 343 is rotatably sleeved on the conveying pipe 335, and the transmission sleeve 343 is fixedly inserted into the bearing seat 312 on the drain chamber 311. The transmission sleeve 343 extends into the working chamber 310. Thus, the drive motor 341 drives the transmission sleeve 343 to rotate via the transmission belt 342. The second filter cartridge 344 is fixed at one end to the drive shaft sleeve 343 and rotates to be sleeved on the adapter pipe 339. Therefore, the second filter cartridge 344 rotates with the drive shaft sleeve 343. The third auger 345 is fixed to the inner wall of the second filter cartridge 344 and is compatible with the first filter cartridge 338. Thus, the third auger 345 and the second filter cartridge 344 rotate synchronously. The wet and dry separation chamber 346 is fixed to the second filter cartridge 344 and rotates to be connected to the working chamber 310. It should be noted that the wet and dry separation chamber 346 and the working chamber 310 rotate in a sealed manner. Therefore, the wet and dry separation chamber 346 and the second filter cartridge 344 rotate synchronously.

[0062] It should be noted that the mesh size of the second filter cartridge 344 is smaller than that of the first filter cartridge 338, so as to perform secondary filtration on the dirt filtered out by the first filter cartridge 338.

[0063] Furthermore, the second filter cartridge 344 is fitted onto the first filter cartridge 338, and the wet-dry separation chamber 346 is fitted onto the second filter cartridge 344. Thus, it can be seen that the sewage eventually converges inside the wet-dry separation chamber 346.

[0064] It should be noted that the dry and wet separation chamber 346 has multiple liquid outlets evenly arranged at the end away from the conveying pipe 335 to facilitate the discharge of sewage.

[0065] It should be further noted that the first filter cartridge 338 and the second filter cartridge 344 are connected to each other at the end near the adapter tube 339, wherein the two end faces of the first filter cartridge 338 and the second filter cartridge 344 are conical, and the conical end faces of the first filter cartridge 338 and the second filter cartridge 344 are similar in shape.

[0066] It should be further noted that the spiral direction of the third auger 345, the second auger 337, and the first auger 333 are the same, and their rotation direction is also the same.

[0067] Therefore, the sewage pumped by the sewage pump 320 is transported to the first filter cartridge 338 through the first auger 333 and the conveying pipe 335. Under the action of the drive motor 341, the transmission shaft sleeve 343 drives the second filter cartridge 344, the third auger 345, and the wet-dry separation chamber 346 to rotate synchronously. At this time, the sewage filtered by the first filter cartridge 338 enters the second filter cartridge 344, which contains a small amount of dirt. The third auger 345 rotates on the outer wall of the first filter cartridge 338 under the rotation of the second filter cartridge 344, scraping off the dirt adhering to the first filter cartridge 338 and transporting it to the connection between the first filter cartridge 338 and the second filter cartridge 344. The sewage in the second filter cartridge 344, after being filtered by the second filter cartridge 344, converges into the wet-dry separation chamber 346, and finally flows through the wet-dry separation chamber 346 and the drainage chamber 346. The drain hole 347 at the junction of 11 converges into the drain chamber 311, and then is transported by the first pump 21 to the liquid treatment tank 2 for pretreatment. At this time, the dirt in the first filter cartridge 338 and the second filter cartridge 344 is transported by the second screw conveyor 337 and the third screw conveyor 345 respectively and finally converges into the transfer pipe 339. Under the rotational transport action of the second screw conveyor 337 and the third screw conveyor 345, it is finally squeezed out from the transfer pipe 339 and discharged to the outside. This design allows the engineering vehicle 1 to flexibly treat decentralized rural sewage and separate the sewage into dry and wet parts, so that the debris in the liquid treatment tank 2 is minimized and the sewage capacity in the liquid treatment tank 2 is guaranteed. At the same time, the engineering vehicle 1 can be used to pretreat the sewage and then transport it to a professional site for fine treatment, avoiding large-scale pipeline investment and reducing costs.

[0068] In related technologies, during the use of the emergency treatment vehicle for decentralized rural sewage treatment facilities, the discharge chamber 311 will inevitably become clogged as the usage time increases. If this clog is not addressed, it will easily lead to blockage of the discharge chamber 311, resulting in a decrease in the treatment efficiency of the emergency treatment vehicle for decentralized rural sewage treatment facilities during actual use.

[0069] According to some embodiments of this application, such as Figure 9 As shown, a sewage discharge mechanism 400 is installed inside the liquid discharge chamber 311, and the sewage discharge mechanism 400 is fixedly connected to the dry and wet separation chamber 346.

[0070] The sewage discharge mechanism 400 includes a driven disc 410 and a scraper 420. The driven disc 410 is fixed to the dry and wet separation chamber 346, so the driven disc 410 and the dry and wet separation chamber 346 rotate synchronously, and the scraper 420 is fixed to the driven disc 410.

[0071] Specifically, the scrapers 420 are arranged in a circumferential array on the driven disk 410, and the scrapers 420 are in contact with the inner wall of the drain chamber 311.

[0072] Understandably, during the use of this emergency treatment vehicle applicable to decentralized rural sewage treatment facilities, the dry-wet separation chamber 346 rotates under the action of the drive motor 341, while the drain chamber 311 is fixed to the working chamber 310. Therefore, the scraper 420 and the driven plate 410 rotate synchronously with the dry-wet separation chamber 346. Since the scraper 420 is in contact with the inner wall of the drain chamber 311, the rotating scraper 420 continuously scrapes the inner wall of the drain chamber 311, preventing the drain chamber 311 from being clogged by the small amount of debris contained in the sewage if it has not been treated for a long time.

[0073] In related technologies, the emergency treatment vehicle applicable to decentralized rural sewage treatment facilities inevitably leaves residual dirt in the second auger 337, the first filter cartridge 338, the second filter cartridge 344, the third auger 345, and the dry-wet separation chamber 346 after treating the sewage. If this dirt is not treated in time, it is very easy for scale to form in the first filter cartridge 338, the second filter cartridge 344, and the dry-wet separation chamber 346, making it impossible for the equipment to complete dry-wet separation the next time it is used.

[0074] According to some embodiments of this application, such as Figure 11 As shown, the separation assembly 330 is provided with an auxiliary mechanism 500, which includes a second infusion pump 510 and a nozzle 520. The second infusion pump 510 is fixed to the engineering vehicle 1, and the output end of the second infusion pump 510 is connected to the connecting pipe 334. It should be noted that the input end of the second infusion pump 510 is connected to an external water source for the second infusion pump 510 to draw water and deliver it into the connecting pipe 334. The nozzle 520 is fixedly connected to the second drive shaft 336, and the nozzle 520 is spirally designed along the axial direction of the second drive shaft 336.

[0075] The first drive shaft 332 is a hollow design with openings at both ends, and a through hole is provided on the side wall of the first drive shaft 332 inside the connecting pipe 334, so that the water source drawn by the second infusion pump 510 can enter the first drive shaft 332.

[0076] The second drive shaft 336 is a hollow design with one end closed, and the second drive shaft 336 is connected to the first drive shaft 332.

[0077] Understandably, the water source in the first drive shaft 332 will be transported to the second drive shaft 336 and sprayed out through the nozzle 520 fixedly connected to the second drive shaft 336.

[0078] Therefore, it can be understood that after using the emergency treatment vehicle suitable for decentralized rural sewage treatment facilities, the second infusion pump 510 is started to supply water from the outside to the first drive shaft 332 and the second drive shaft 336, which is then sprayed out by the nozzle 520. During this process, the delivery motor 331 can be started to drive the second drive shaft 336 and the second auger 337 to rotate, and the drive motor 341 can be started to drive the second filter cartridge 344, the third auger 345 and the dry-wet separation chamber 346 to rotate, thereby causing the nozzle 520 to rotate along with the second drive shaft 336. The water spraying, along with the rotation of the second auger 337 and the third auger 345, scrapes the dirt washed down by the water flow off the first filter cartridge 338. Furthermore, the rotating second filter cartridge 344 and the dry-wet separation chamber 346 can also wash the dirt off themselves. Finally, the wastewater containing dirt after rinsing can be pumped out by the first infusion pump 21 and discharged to the outside. The output end of the first infusion pump 21 needs to be removed from the liquid treatment tank 2. This design avoids the scale buildup of residual dirt, which would prevent the emergency treatment vehicle suitable for decentralized rural sewage treatment facilities from being unable to complete the dry-wet separation the next time it is used.

[0079] It should be noted that the specific models and specifications of the first infusion pump 21, bearing housing 312, sewage pump 320, conveying motor 331, first auger 333, second auger 337, drive motor 341, third auger 345, second infusion pump 510, and nozzle 520 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0080] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
