Description

Technical Field

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

[0002] Traditional wastewater treatment systems typically employ a modular design, comprising multiple large pieces of equipment such as front-end bar screens, mid-stage sedimentation or biological treatment, and back-end deep filtration. These systems are space-consuming and complex to install, making them unsuitable for mobile or temporary wastewater treatment needs. In contrast, mobile integrated wastewater treatment units highly integrate physical filtration and solid-liquid separation functions into a single transportable module, achieving a compact design that facilitates rapid installation and operation. Therefore, they are widely used in emergency rescue, temporary camps, remote mountainous areas, and construction sites.

[0003] However, due to the special nature of the application environment, wastewater often contains a large amount of solid particles such as silt and gravel, which can easily cause clogging of the filtration system. In particular, the first (top) filter disc in the device is prone to clogging because it is in direct contact with high concentrations of impurities.

[0004] Therefore, to solve the above problems, existing technologies typically add scrapers or brushes to the top filter disc for mechanical scraping and cleaning of the filter disc surface. Although such methods can remove some blockages, in actual use, the scraper moving along the surface of the filter disc can easily form a shearing structure with the rigid filter disc, crushing the mud and sand into finer particles, thereby reducing filtration efficiency. Furthermore, particles embedded in the filter holes are difficult to remove effectively, and long-term accumulation will still lead to a decrease in filtration efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a mobile integrated sewage treatment equipment to solve the technical problem that the scraper sweeping cleaning method in the prior art is prone to crushing mud and sand particles.

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0007] A mobile integrated sewage treatment device includes a cylindrical water tank. A main shaft is installed inside the cylindrical water tank. A top filter disc and a multi-layer purification filter disc are coaxially fixedly sleeved on the main shaft. A lifting plate is installed between the top filter disc and the multi-layer purification filter disc. The lifting plate is coaxially and slidably installed outside the main shaft through a tie rod structure. A plurality of pins are installed on the lifting plate, and the plurality of pins are configured to correspond one-to-one with a plurality of filter holes on the top filter disc.

[0008] The tie rod structure includes a coaxial through hole, a tie rod, a through groove, and a connecting rod. The coaxial through hole is coaxially disposed in the middle of the main shaft. The tie rod is axially slidably disposed in the coaxial through hole. The through groove passes radially through the main shaft. The connecting rod is fixedly disposed on the tie rod and slidably disposed in the through groove. The connecting rod is connected to the lifting plate.

[0009] In a preferred embodiment of this utility model, the connecting rod is connected to the lifting plate via a trapezoidal block, one inclined side of the trapezoidal block is fixedly connected to the lifting plate, the bottom flat side of the trapezoidal block is fitted onto the opening of the through groove, and the trapezoidal block slides on the outer surface of the through groove in a manner that closes the opening of the through groove.

[0010] As a preferred embodiment of this utility model, an outer sliding groove is provided on the outer wall of the main shaft, both above and below the trapezoidal block. A housing stop is provided on the outer side of the outer sliding groove. The housing stop is fixedly connected to the main shaft. The housing stop covers the outer side of the outer sliding groove to form a sliding cavity for accommodating the trapezoidal block.

[0011] As a preferred embodiment of the present invention, the end of the sliding cavity away from the trapezoidal block is connected to a curved channel, the end of the curved channel is connected to the coaxial through hole, and a first one-way diaphragm is provided at the opening of the curved channel, the first one-way diaphragm can only be opened in the direction of the curved channel.

[0012] The bottom end of the main shaft is located below the multi-layer purification filter disc. The coaxial perforation is provided through the bottom end of the main shaft. A sealing ring is slidably disposed in the coaxial perforation. The sealing ring is fixedly connected to the pull rod. A second one-way diaphragm is provided on the sealing ring. The second one-way diaphragm can only be opened towards the inside of the coaxial perforation.

[0013] As a preferred embodiment of this utility model, a handle pull tab is provided at the top of the pull rod.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This invention features a lifting plate positioned below the top filter disc. A pull rod moves the lifting plate upwards, lifting out clogging particles from the filter holes of the top filter disc. This avoids the horizontal scraping method that breaks down clogging particles, resulting in finer particles and improving the effectiveness of the cleaning process. Furthermore, the device incorporates a housing baffle, a first unidirectional diaphragm, and a second unidirectional diaphragm. During the lifting process, the axial sliding of the pull rod draws purified water from the bottom into the coaxial perforation and sprays it towards both ends of the trapezoidal block. This reduces the accumulation of fine particles along the sliding path of the trapezoidal block, thereby minimizing wear during its movement. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 6As shown, this utility model provides a mobile integrated sewage treatment device, including a cylindrical water tank 1. The cylindrical water tank 1 is the main container of the device, made of corrosion-resistant materials (such as stainless steel or high-strength engineering plastics), and is used to hold the sewage to be treated. The cylindrical water tank 1 has an inlet at the top and an outlet at the bottom, and is equipped with a movable base to facilitate the movement and deployment of the device in different sewage treatment scenarios. Alternatively, it can be moved and deployed by means of hoisting or other methods. A biological purification module (not shown in the figure) can be further configured at the bottom of the cylindrical water tank 1 for deep purification of the water source after the top filter disc 3 and multi-layer purification filter disc 4 have filtered particulate matter.

[0027] like Figure 1 and Figure 3 As shown, a main shaft 2 is installed inside the cylindrical water tank 1. The main shaft 2 is a hollow cylindrical structure and is fixedly installed on the central axis of the cylindrical water tank 1. A top filter disc 3 and a multi-layer purification filter disc 4 are coaxially fixed on the main shaft 2. The top filter disc 3 is located above the main shaft 2 and is used for preliminary filtration of large particulate impurities in the sewage. The multi-layer purification filter disc 4 is located below the top filter disc 3. The pore size of each filter disc decreases progressively to achieve staged filtration, removing suspended solids and pollutants of different particle sizes. Activated carbon, gauze, cotton, and other filter materials can be added according to actual usage to form a more efficient filtration method. Since the top filter disc 3 directly contacts large particles of silt, and the impact force of the directly poured water containing silt is relatively large, the top filter disc 3 is made of rigid material, while the bottom multi-layer purification filter disc 4 can be made of non-rigid material.

[0028] A lifting plate 5 is installed between the top filter plate 3 and the multi-layer purification filter plate 4. As shown in the figure, the lifting plate 5 is a ring with multiple strips, and pins 6 are installed on the strips. The pins 6 are positioned corresponding to the filter holes of the top filter plate. The lifting plate 5 is coaxially and slidably mounted outside the main shaft 2 via a tie rod structure. Multiple pins 6 are evenly distributed on the lifting plate 5, and the number and position of the pins 6 correspond one-to-one with the filter holes on the top filter plate 3. The pins 6 are made of wear-resistant materials (such as ceramic or hard alloy), with a conical or cylindrical tip and a diameter slightly smaller than the filter hole diameter, so that they can be inserted into the filter holes when the lifting plate 5 rises to remove any blockages embedded within them.

[0029] like Figure 3 and Figure 5As shown, specifically, the pull rod structure is used to drive the up-and-down movement of the lifting plate 5, and it includes a coaxial through hole 7, a pull rod 8, a through groove 9, and a connecting rod 10. The coaxial through hole 7 is a circular channel that passes through the main shaft 2 axially, and it is coaxially set in the middle of the main shaft 2. The pull rod 8 is slidably set in the coaxial through hole 7, and its top end is provided with a handle pull piece 18 for easy manual pulling by the operator. The through groove 9 is a rectangular groove that passes through the main shaft 2 radially, and it is opened perpendicular to the axial direction of the main shaft 2. The through groove 9 has a certain height so that the connecting rod 10 can slide inside it, allowing the ejector pin 6 to be inserted into the filter hole. The through groove 9 communicates with the coaxial through hole 7. The connecting rod 10 is a horizontally set rod body, fixed to the rod wall of the pull rod 8. The connecting rod 10 slides longitudinally in the through groove 9 and is connected to the lifting plate 5 through the through groove 9. When the pull rod 8 moves up and down, the connecting rod 10 slides in the through groove 9, driving the lifting plate 5 to move axially along the main shaft 2, so as to lift the clogged particles out of the filter plate from bottom to top.

[0030] Furthermore, to prevent particulate matter in the cylindrical water tank 1 from remaining in the through groove 9 or entering the coaxial perforation 7 through the through groove 9, affecting the sliding of the connecting rod 10 and the tie rod 8 and causing wear, this embodiment further connects the connecting rod 10 to the lifting plate 5 through the trapezoidal block 11. The specific implementation method is as follows:

[0031] The trapezoidal block 11 is a metal or rigid plastic component with a sloping side and a flat bottom side. The sloping side is fixed to the outer edge of the lifting plate 5 by bolts or welding, while the flat bottom side is fitted against the opening of the through-slot 9. The sloping design of the trapezoidal block 11 allows particles adhering to its end surface to slide down the sloping side when sliding on the outer surface of the through-slot 9, rather than being driven by the trapezoidal block 11 to slide synchronously and rub against the main shaft 2. Furthermore, the fact that the trapezoidal block 11 slides with its flat bottom side against the opening of the through-slot 9 reduces the possibility of sewage entering the through-slot 9 by sealing the opening, thus protecting the internal structure of the main shaft 2 from contamination. The width of the flat bottom side of the trapezoidal block 11 is slightly larger than the width of the through-slot 9 opening (e.g., 10%-20% wider) to ensure stability during sliding.

[0032] The trapezoidal block 11 is set to be relatively long so that it fits the opening of the closed through groove 9 when it is not sliding initially. During the process from the beginning to the end of its sliding, its entire length is to close the opening of the through groove 9, so as to prevent particles from entering the through groove 9 during the sliding process.

[0033] To reduce the sliding path of fine particles into the trapezoidal block 11 and reduce the wear of the trapezoidal block 11 during the sliding process, this embodiment further provides a housing baffle 13 on the outside of the through groove 9. The housing baffle 13 is placed on the outside of the trapezoidal block 11 to reduce the possibility of particles contacting the trapezoidal block 11.

[0034] like Figure 3 and Figure 5 As shown, specifically, outer sliding grooves 12 are provided on the outer wall of the main shaft 2, both above and below the trapezoidal block 11. A housing stop 13 is provided on the outer side of the outer sliding grooves 12, and the housing stop 13 is fixedly connected to the main shaft 2. The housing stop 13 covers the outer side of the outer sliding grooves 12, forming a sliding cavity to accommodate the trapezoidal block 11. The sliding cavity acts as a protective sleeve around the sliding trapezoidal block 11, thereby reducing wear during the sliding process. Furthermore, the sliding cavity connects to the curved channel 14, forming a flow guide channel. Through the impact of water flow in the flow guide channel, the problem of particulate matter entering the sliding cavity and interfering with the sliding of the trapezoidal block 11 is further reduced by reverse flushing. Specifically:

[0035] The end of the sliding cavity away from the trapezoidal block 11 is connected to a curved channel 14. The curved channel 14 is an L-shaped pipe built into the main shaft 2, with one end connected to the sliding cavity and the other end connected to the coaxial perforation 7. A first one-way diaphragm 15, made of flexible silicone material, is provided at the opening of the curved channel 14, allowing liquid to flow only from the coaxial perforation 7 to the curved channel 14.

[0036] like Figure 5 As shown, the bottom end of the main shaft 2 is located below the multi-layer purification filter plate 4. The top of the coaxial perforation 7 is closed, and the coaxial perforation 7 extends through the bottom end of the main shaft 2 to draw clean water filtered by the multi-layer purification filter plate 4. A sealing ring 16 is slidably installed inside the coaxial perforation 7. The sealing ring 16 is an annular seal made of wear-resistant rubber or silicone, and is fixedly connected to the pull rod 8, moving up and down synchronously with the pull rod 8. A second one-way diaphragm 17 is provided on the sealing ring 16, also made of flexible silicone material, which only allows liquid to flow from the outside of the bottom end of the main shaft 2 into the inside of the coaxial perforation 7.

[0037] When the lever 8 is pulled upward, the negative pressure causes the first one-way membrane 15 to open and the second one-way membrane 17 to close. At this time, the clean water source after multiple filtrations below the multi-layer purification filter plate 4 flows through the perforation into the sliding cavity, rinsing the particles in the trapezoidal block 11 and the through groove 9. This reduces the possibility of the trapezoidal block 11 coming into contact with particles during the sliding process when the lifting plate 5 moves upward.

[0038] When the lever 8 is pushed down, the sealing ring 16 causes the second one-way diaphragm 17 to open and the first one-way diaphragm 15 to close. At this time, the water source outside the sliding cavity with more particles will not enter the coaxial perforation 7 through the first one-way diaphragm 15, while the clean water source below the multi-layer purification filter plate 4 enters the coaxial perforation 7 through the second one-way diaphragm 17 to replenish the water source in the coaxial perforation 7 and prepare for the next backwashing action.

[0039] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
