Description

Technical Field

[0001] This disclosure relates to the field of wastewater treatment technology, and more specifically, to a water treatment system for a shower truck. Background Technology

[0002] Mobile shower trucks play a crucial role in ensuring hygiene during emergency rescue and field operations, and the efficiency of their water recycling system directly limits the equipment's continuous operation. Currently, the wastewater treatment in shower trucks generally employs a basic "sedimentation-filtration-disinfection" process, which faces severe challenges in practical applications. Shower wastewater is rich in components such as human hair, fiber debris, and sebum, placing multiple pressures on the treatment system: hair impurities, due to their strong entanglement properties, easily penetrate the interception of traditional static filters, forming dense blockages at pump impellers and pipe bends. Statistics show that in shower trucks serving an average of 200 people per day, up to 78% of downtime is due to such blockages. Although some solutions attempt to introduce shredders to cut the hair, this brings new problems such as a sharp increase in energy consumption, excessive operating noise, and the generation of microplastic byproducts. At the same time, the unique characteristics of the on-board environment further exacerbate the treatment difficulty—the continuous shaking during travel causes the settled flocs in the sedimentation chamber to be repeatedly resuspended, resulting in a heavy metal and colloidal particle removal rate of less than 40%, forcing subsequent filtration units to operate under overload conditions.

[0003] More concerning is the significant deficiency in the control of grease contamination in existing systems. Sebum and grease from shower wastewater quickly adhere to the filter media surface, causing the micropores of activated carbon adsorption materials to cake and fail. Their saturation cycle is shortened by more than 60% compared to stationary equipment, not only reducing odor removal efficiency but also creating a breeding ground for bacteria. At the microbial control level, relying on simple sand filtration or single disinfectants is insufficient to effectively inactivate drug-resistant pathogens. The total bacterial count in reclaimed water consistently exceeds standards by around 35%, posing a significant health and safety hazard. While some technologies have attempted to integrate flotation or ultrafiltration membrane modules to improve treatment depth in recent years, the limited space on mobile devices restricts traditional flotation devices to below 50% due to low dissolved air efficiency and excessively large bubble size. Furthermore, when ultrafiltration membranes directly treat high-turbidity raw water, the membrane surface fouling rate increases exponentially, requiring backwashing up to twice per hour, severely exceeding the practical requirements of mobile equipment. The aforementioned defects collectively expose the systemic deficiencies of the existing system in three dimensions: anti-clogging capability, operational stability, and safety of effluent water quality. There is an urgent need to break through the technical bottlenecks of efficient hair interception, dynamic anti-disturbance sedimentation, deep grease separation, and synergistic control of microorganisms through innovative process design, so as to fundamentally improve the water resource recycling efficiency of mobile shower equipment.

[0058] The embodiments of the present invention have the following beneficial effects:

[0059] The shower truck's interior is divided into multiple shower rooms, with drain pipes from each room connected to a sedimentation tank. Wastewater from the shower rooms flows into the sedimentation tank for settling. An extraction pump draws the settled wastewater from the sedimentation tank and discharges it through pipes into a vortex tube assembly. As the wastewater enters the vortex tube assembly, it forms a vortex. This vortex enters the hair separation assembly and flows along the inner wall of the separation chamber. A rotating brush head rotates continuously, in the opposite direction to the vortex flow. Hair and paper scraps within the vortex are entangled on the rotating brush head, which then intercepts the hair. The wastewater passing through the hair separation assembly enters the air flotation assembly, where air stones are continuously released. Dense bubbles are released, carrying grease from the flotation unit to the surface and ultimately discharging it from the flotation unit. The middle layer of water from the flotation unit enters the activated carbon filter chamber, which is filled with activated carbon. Odors are adsorbed through the micropores on the surface of the activated carbon. An ultrafiltration tank can be added between the activated carbon filter chamber and the filtered water storage tank to filter microorganisms in the wastewater. After filtration, the water is finally discharged into the filtered water storage tank for storage and is used as shower water along with the water stored in the water tank. The vortex tube converts the straight water flow into a tangential vortex flow, increasing the probability of impurities contacting the inner wall. The reverse rotating brush head generates a shear force multiplication effect, improving the efficiency of hair entanglement. The sedimentation tank also serves as a buffer water tank, reducing water quality fluctuations caused by vehicle shaking.

Detailed Implementation

[0073] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0074] In related technologies, existing shower truck water treatment systems have limited filtration effects, and hair easily clogs the pipes, leading to frequent maintenance of the pipe system.

[0075] Based on this, a shower cart water treatment system is provided, including: a drain pipe 200 inside the shower room 100, and a sedimentation tank 300 located at the bottom of the shower cart, with one end of the drain pipe 200 away from the shower room 100 connected to the sedimentation tank 300; an extraction pump 400 connected to the sedimentation tank 300, with the output end of the extraction pump 400 connected to a vortex tube assembly 500; a hair separation assembly 600, with its input end connected to the output end of the vortex tube assembly 500; and an air flotation assembly 700, which is connected to the hair separation assembly 500. The outlet pipe of component 600 is connected; the activated carbon filter chamber 800 is connected to the outlet pipe of the air flotation component 700; the filtered water storage chamber 900 is connected to the outlet pipe of the activated carbon filter chamber 800; the hair separation component 600 includes: a separation chamber 611 and a rotary brush head 620 disposed in the separation chamber 611; wherein the sewage in the sedimentation chamber 300 forms a vortex through the vortex tube component 500, the vortex flows along the inner wall of the separation chamber 611, and the rotation direction of the rotary brush head 620 is opposite to the direction of the vortex.

[0076] In the above embodiment, the shower cart's interior is divided into multiple shower rooms 100. The drain pipes 200 of each shower room 100 are centrally connected to a sedimentation tank 300. Wastewater from the shower rooms 100 enters the sedimentation tank 300 through the drain pipes 200 for sedimentation. An extraction pump 400 extracts the sedimented wastewater from the sedimentation tank 300 and discharges it through a pipe into a vortex tube assembly 500. When wastewater enters the vortex tube assembly 500 through the pipe, a vortex is formed. The vortex enters the hair separation assembly 600 and flows along the inner wall of the separation chamber 611 of the hair separation assembly 600. A rotating brush head 620 rotates continuously in the opposite direction to the vortex flow. Hair and paper scraps within the vortex are entangled on the rotating brush head 620, which intercepts the hair. The wastewater passing through the hair separation assembly 600 enters the air flotation assembly. Inside the 700, the air stone 770 in the air flotation unit 700 continuously releases dense bubbles. These bubbles carry the grease in the air flotation unit 700 to the surface and are eventually discharged from the air flotation unit. The middle layer of water from the air flotation unit enters the activated carbon filter chamber 800, which is filled with activated carbon. Odors are adsorbed through the micropores on the surface of the activated carbon. An ultrafiltration tank can also be added between the activated carbon filter chamber 800 and the filtered water storage tank 900 to filter microorganisms in the wastewater. After filtration, the water is finally discharged into the filtered water storage tank 900 for storage and is used as shower water along with the water stored in the water tank. The vortex tube converts the straight water flow into a tangential vortex flow, increasing the probability of impurities contacting the inner wall. The reverse rotating brush head 620 generates a shear force multiplication effect, improving the efficiency of hair entanglement. The sedimentation tank 300 also serves as a buffer water tank, reducing water quality fluctuations caused by vehicle shaking.

[0077] Please see Figures 1-10 In some embodiments, the vortex tube assembly 500 includes: a first sleeve 510, whose circumferential outer wall is connected to the extraction pump 400; a flow-encircling column 520, arranged on the axis of the first sleeve 510; wherein the circumferential outer wall of the flow-encircling column 520 is spaced apart from the inner wall of the first sleeve 510; a sloping groove 530, one end of which points to the center of the end wall of the flow-encircling column 520, and the other end of which is connected to the circumferential outer wall of the flow-encircling column 520, and multiple sloping grooves 530 are arranged in a circumferential array on the end wall of the flow-encircling column 520; a baffle 540, which is disposed on the side of the flow-encircling column 520 near the sloping groove 530, and the baffle 540 is spaced apart from the end wall of the flow-encircling column 520; a first water outlet 550, which is disposed at the center of the baffle 540; and a first diffuser 560, the large-diameter end of which is connected to the end of the first sleeve 510 near the first water outlet 550 on the baffle 540, and the small-diameter end of which is connected to the hair separation assembly 600.

[0078] In the above embodiment, the extraction pump 400 fills the inner wall of the first sleeve 510 with water. After passing through the circumferential outer wall of the flow column 520, the water enters the end wall of the flow column 520 and flows into the inclined groove 530 towards the center of the end wall of the flow column 520. Since each inclined groove 530 is inclined towards the center of the end wall of the flow column 520, each stream of water forms a vortex when passing through the inclined groove 530. The vortex enters the diffuser through the first water outlet 550 of the baffle 540 and finally enters the hair separation component 600, flowing along the inner wall of the separation chamber 611 of the hair separation component 600. When the water flows through the flow column 520, the water impacts the column tangentially, generating initial rotational momentum. After entering the inclined channel 530, the radial water flow is converted into a spiral centripetal flow. The baffle 540 gathers multiple streams of water from the inclined channel 530 to form a stable vortex core. The diffuser reduces the flow velocity and maintains the vortex shape before entering the separation chamber 611. The baffle 540 prevents the vortex from spreading too early and maintains the rotational energy entering the separation chamber 611. The diffuser converts turbulent kinetic energy into pressure energy, preventing the high-speed water flow from dispersing the hair entanglement layer, improving the hair capture rate, and providing an optimized fluid environment for the subsequent hair separation component 600.

[0079] Please see Figures 1-10 In some embodiments, the hair separation assembly 600 includes: a sealing cover assembly 610 and a rotary brush head 620 and an automatic cleaning assembly 630 disposed within the sealing cover assembly 610; the sealing cover assembly 610 includes: a second expanding tube 612, the small diameter end of which is connected to the small diameter end of the first expanding tube 560; a second sleeve 613, disposed at the end of the second expanding tube 612 away from the first expanding tube 560; a sealing plate 614, disposed at the end of the second sleeve 613 away from the second expanding tube 612, the sealing plate 614 being connected to the air flotation assembly 700; a cleaning strip hole 615, disposed on the circumferential outer wall of the second sleeve 613, the length direction of which is parallel to the axis of the second sleeve 613; the automatic cleaning assembly 630 passes through the cleaning strip hole 615 and is disposed within the second sleeve 613.

[0080] In the above embodiment, the small-diameter end of the second diffuser 612 is connected to the small-diameter end of the first diffuser 560, further slowing down the eddy current speed and increasing the water pressure. When the eddy current passes through the second diffuser 612, it enters the second sleeve 613 and flows spirally along the inner wall of the second sleeve 613. The rotary brush head 620 rotates on the inner wall of the second sleeve 613 in the opposite direction to the eddy current. The automatic cleaning component 630 is used to automatically clean the hair wrapped around the rotary brush head 620. The continuous expansion structure further slows down the water flow speed and increases the pressure. The second sleeve 613 is connected to the outlet end of the second diffuser 612, and its circumferential outer wall has an axially extending cleaning strip hole 615. The sealing plate 614 seals the far end of the sleeve and communicates with the air flotation machine component 700. The rotary brush head 620 is located inside the second sleeve 613. Its rotation direction is opposite to that of the vortex. It efficiently wraps the hair that moves with the vortex wall through the reverse motion. The automatic cleaning component 630 extends into the sleeve through the cleaning strip hole 615 to achieve real-time cleaning of the rotary brush head. Through the coordinated flow stabilization and pressurization of the double diffuser tube, the dynamic capture of the reverse rotating brush head, and the embedded self-cleaning mechanism, the efficient separation and automatic maintenance of hair are completed in a closed environment, avoiding the problem of hair clogging the pipeline.

[0081] Please see Figures 1-10 In some embodiments, the rotary brush head 620 includes: a first brush head body 621 disposed on the axis of the second sleeve 613; and a drive shaft 622, one end of which is connected to the rotating shaft of the first brush head body 621, and the other end passes through the sealing plate 614 and is positioned towards the air flotation machine assembly 700; and a drive motor 623 mounted on the air flotation machine assembly 700, with its output shaft connected to the drive shaft 622 by a belt.

[0082] In the above embodiment, when the extraction pump 400 starts to supply water to the hair separation component 600, the drive motor 623 starts, and the output shaft rotates to transmit torque through the belt, causing the drive shaft 622 to rotate, which in turn drives the first brush head body 621 to rotate in the opposite direction of the vortex. When the first brush head body 621 rotates in the opposite direction, it collects the hair carried by the vortex.

[0083] Please see Figures 1-10In some embodiments, the automatic cleaning assembly 630 includes: a drive plate 631 disposed on the circumferential outer wall of the drive shaft 622, the drive plate 631 being concentrically arranged with the drive shaft 622; wherein the drive plate 631 is a partially missing circular plate structure; an L-shaped rod 632, one end of which abuts against the circumferential outer wall of the drive plate 631; a hinge rod 633, one end of which is hinged to the corner of the L-shaped rod 632, and the other end of which is mounted on the surface of the sealing plate 614; a slide rail 634, the end of the L-shaped rod 632 away from the drive plate 631 being slidably disposed in the slide rail 634; and a cleaning comb 635 movably disposed within the cleaning strip hole 615, the teeth of which are close to the first brush head. The main body 621 is provided, and the other end is connected to the slide rail 634. The slide rail 634 is arranged parallel to the outer wall of the cleaning comb 635 in the length direction. A torsion spring 636 is arranged at the end of the hinge rod 633 near the L rod 632. One end of the torsion spring 636 is connected to the hinge rod 633, and the other end is connected to the L rod 632. The torsion spring 636 is used to pull the end of the L rod 632 near the drive plate 631 to always abut against the circumferential outer wall of the drive plate 631. A rain plate 637 is provided outside the second sleeve 613, and the rinsing end is set towards the cleaning comb 635. A hair collection chamber 638 is provided on the side of the cleaning comb 635 away from the rain plate 637.

[0084] In the above embodiment, when the drive motor 623 drives the drive shaft 622 to rotate, it drives the drive plate 631 on the drive shaft 622 to rotate simultaneously. The arc-shaped outer wall of the drive plate 631 abuts against one end of the L-rod 632. At this time, the distance between the L-rod 632 and the axis of the drive shaft 622 is at its maximum. The other end of the L-rod 632 is vertically set, and the cleaning comb 635 is located inside the second sleeve 613. When the first brush head body 621 rotates, the protrusions arrayed on the surface of the first brush head body 621 pass through the cleaning comb 635, and the cleaning comb 635 scrapes off the bristles on the first brush head body 621. When the drive plate 631 rotates to a plane and contacts the L-rod 632, the distance between the L-rod 632 and the axis of the drive shaft 622 is at its minimum. At this time, the L-rod 632 swings around its corner, and the torsion spring 6... 36. Pull the L-bar 632 close to the drive plate 631 towards the outer wall of the drive plate 631. The other end of the L-bar 632 tilts up, dragging the cleaning comb 635 out of the cleaning strip hole 615. The cleaning comb 635 enters the side of the rain plate 637. The rain plate 637 sprays water evenly on the cleaning comb 635, causing the hair on the cleaning comb 635 to be washed into the hair collection chamber 638. Then the drive plate 631 continues to rotate with the drive shaft 622, and the cleaning comb 635 re-enters the cleaning strip hole 615 to scrape the hair off the first brush head body 621. The hair scraping, component withdrawal, water rinsing and resetting actions are completed synchronously through a single power source, realizing a self-cleaning cycle with zero human intervention in a closed environment.

[0085] Please see Figures 1-10In some embodiments, the air flotation unit 700 includes: a temporary storage chamber 710, the top surface of which is connected to the sealing plate 614 pipe; and a treatment chamber 720, disposed on one side of the temporary storage chamber 710; wherein a strip-shaped water inlet 730 is provided between the treatment chamber 720 and the temporary storage chamber 710, the strip-shaped water inlet 730 connecting the treatment chamber 720 and the lower middle part of the temporary storage chamber 710; a water-turning plate 740, disposed inside the treatment chamber 720 near the strip-shaped water inlet 730; and a foam removal chamber 750, closed at the bottom and open at the top. The top of the foam removal chamber 750 is flush with the top of the water-discharging plate 740. The foam removal chamber 750 is located inside the treatment chamber 720 on the side away from the water-discharging plate 740. The foam collection chamber 760 is located at the bottom of the treatment chamber 720 and is pipe-connected to the foam removal chamber 750. The air stone 770 is located between the water-discharging plate 740 and the strip-shaped water inlet hole 730 and is pipe-connected to the air pump 771. The drainage chamber 780 is closed at the top and open at the bottom and is located between the foam removal chamber 750 and the inner wall of the treatment chamber 720. The drainage chamber 780 is pipe-connected to the activated carbon filter chamber 800.

[0086] In the above embodiment, after passing through the hair separation component 600, the wastewater enters the temporary storage chamber 710 from the top, where it briefly stays and settles again. A forced discharge valve is provided on the bottom surface of the temporary storage chamber 710 to forcefully discharge the sediment in the temporary storage chamber 710. Subsequently, the wastewater enters one side of the water-turning plate 740 through the strip-shaped water inlet 730 and enters the treatment chamber 720 from the top of the water-turning plate 740. The air stone 770 is supplied with air by the air pump 771, generating dense fine bubbles. The bubbles carry the sediment to the water surface and finally the bubbles carrying the sediment enter the foam removal chamber 750 for foam removal. The sediment in the foam removal chamber 750 flows through the pipe to the foam collection chamber 760. The wastewater treated by the air flotation component 700 is discharged through the drainage chamber 780 and finally enters the activated carbon filter chamber 800 for filtration.

[0087] Please see Figures 1-10 In some embodiments, the air flotation machine assembly 700 further includes a skimmer assembly 790, which includes: a drive rod 791 with a first bevel gear 792 at its top end; a drive shaft 622 with a second bevel gear 793 at one end away from the first brush head body 621, the second bevel gear 793 meshing with the first bevel gear 792; a drive tube 794, horizontally arranged, with its middle circumferential outer wall connected to the bottom end of the drive rod 791; and a swing rod 795, one end of which is slidably mounted on the drive rod. Inside the tube 794; slider 796, hinged to the end of the swing rod 795 away from the drive tube 794; skimmer 797, located on the upper part of the treatment chamber 720, extending into the water surface of the treatment chamber 720 from its circumferential outer wall, slider 796 is sleeved on the circumferential outer wall of skimmer 797; slide rod 798, provided in two sets, the two sets of slide rod 798 are spaced apart on the top surface of the treatment chamber 720, both ends of skimmer 797 are sleeved on the circumferential outer wall of slide rod 798; spring 799 is provided between the drive tube 794 and the swing rod 795.

[0088] In the above embodiment, when the drive rod 791 rotates, it drives the second bevel gear 793 to rotate. The rotation of the second bevel gear 793 drives the first bevel gear 792, which meshes with it, to rotate, which in turn drives the drive rod 791 to rotate. When the drive rod 791 rotates, it drives the drive tube 794 to rotate. When the drive rod 791 rotates, it drives the rocker arm 795 to rotate. The spring 799 pushes the rocker arm 795 to always move away from the drive tube 794. When the drive rod 791 rotates, it pushes the scraper... The skimmer 797 slides back and forth on the two slide bars 798, thereby scraping the dirt floating on the water surface into the descum chamber 750 through the reciprocating sliding skimmer 797. At the same time, when the skimmer 797 is pushed to one side of the descum chamber 750, the drive rod 791 moves from one end of the skimmer 797 to the other end, and the slider 796 scrapes off the dirt adhering to the outer circumferential wall of the skimmer 797, preventing the adhering dirt from being carried into the water in the treatment chamber 720 during the resetting process of the skimmer 797.

[0089] Please see Figures 1-10 In some embodiments, the bottom surface of the slider 796 is provided with a second brush head body 7961, which is vertically arranged.

[0090] In the above embodiment, the slider 796 is pushed by the spring 799 and moves against the inner wall of the processing chamber 720. When the slider 796 moves, it drives the second brush head body 7961 located at the lower part of the slider 796 to move. During the movement, the second brush head body 7961 brushes the inner wall of the processing chamber 720 and removes the dirt adhering to the inner wall of the processing chamber 720.
