Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a mobile decentralized wastewater treatment device. Background Technology

[0002] Wastewater treatment refers to the purification of polluted water through physical or chemical processes to meet discharge requirements. Most existing wastewater treatment facilities are fixed-point installations, where wastewater is collected and then purified by these designated facilities.

[0003] The above-mentioned sewage treatment equipment has the following disadvantages when in use: sewage is easily blocked due to long-distance transmission; large-scale centralized treatment of sewage limits the purification capacity of the sewage treatment equipment; large-volume sewage increases water pressure, which places high demands on the quality of the equipment.

[0004] In summary, existing wastewater treatment equipment faces high pressure when treating wastewater centrally, and fixed-point wastewater treatment equipment cannot be moved to the discharge point to treat wastewater in case of emergencies.

[0005] Therefore, this application proposes a mobile decentralized wastewater treatment device to reduce the workload of wastewater treatment equipment. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a mobile decentralized sewage treatment device to solve the problem of high working pressure of centralized sewage treatment equipment mentioned in the prior art.

[0007] To achieve the above and other related objectives, this utility model provides a mobile decentralized sewage treatment device, including a sewage collection mechanism, a sewage separation mechanism on the sewage collection mechanism, the sewage separation mechanism for treating sewage, and the sewage collection mechanism for collecting pollutants;

[0008] The wastewater separation mechanism includes a wastewater treatment cylinder, with an inlet pipe and a drain pipe at each end of the wastewater treatment cylinder. A wastewater filter screen is installed inside the wastewater treatment cylinder near the inlet pipe, and the wastewater filter screen completely covers the opening of the inlet pipe.

[0009] The wastewater filter screen is equipped with a drain pipe that extends to the outside of the wastewater treatment cylinder.

[0010] Preferably, a gap is left between the outer surface of the sewage filter screen and the inner wall of the sewage treatment cylinder.

[0011] Preferably, the sewage pipe is equipped with a valve, which is used to control the opening and closing of the sewage pipe.

[0012] Preferably, the drain pipe is provided with a pressure pump inlet pipe, which is connected to the interior of the drain pipe.

[0013] Preferably, the end of the sewage inlet pipe on the inner wall of the sewage treatment cylinder is provided with a one-way valve;

[0014] When the one-way valve is pressurized from the inlet pipe side, the inside of the inlet pipe is connected to the inside of the sewage treatment cylinder.

[0015] The one-way valve blocks the interior of the sewage inlet pipe from the interior of the sewage treatment cylinder from the pressurized side of the drain pipe.

[0016] Preferably, the one-way valve includes a limiting guide cage, and a return spring and a sealing plug are respectively provided inside the limiting guide cage. The return spring applies elastic pressure to the sealing plug from the side of the inlet pipe near the inlet pipe. The sealing plug can seal the opening of the inlet pipe, and the sealing plug can slide inside the limiting guide cage.

[0017] Preferably, the sealing plug consists of a circular platform and a circular plug shaft. The outer surface of the circular platform is in close contact with the inner wall of the limiting guide cage, and the circular plug shaft can extend into the inside of the sewage inlet pipe and be in close contact with the inner wall of the sewage inlet pipe.

[0021] As described above, the mobile decentralized wastewater treatment equipment of this utility model has the following beneficial effects:

[0022] 1. This utility model sets up a sewage treatment cylinder with an inlet pipe and a drain pipe at both ends. A sewage filter screen is installed inside the sewage treatment cylinder near the inlet pipe, and a drain pipe extends from the filter screen into the sewage collection mechanism. During sewage treatment, the sewage entering through the inlet pipe is filtered by the filter screen, and the treated water is discharged through the drain pipe.

[0034] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0035] Please see Figures 1 to 5 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0036] like Figures 1-3 As shown, this utility model provides a mobile decentralized sewage treatment device, including a sewage collection mechanism 1 and a sewage separation mechanism 2. The sewage separation mechanism 2 is used to treat sewage, and the sewage collection mechanism 1 is used to collect pollutants. In use, sewage is transported to the inside of the sewage separation mechanism 2 through a water pump or other device. After being treated by the sewage separation mechanism 2, the treated water is directly discharged, while the pollutants are discharged to the sewage collection mechanism 1 for collection in subsequent treatment.

[0037] Specifically, the sewage separation mechanism 2 includes a sewage treatment cylinder 21, with an inlet pipe 22 and a drain pipe 23 at both ends. Sewage enters the sewage treatment cylinder 21 from the inlet pipe 22, and the treated water is discharged from the drain pipe 23. A sewage filter screen 25 is provided at the end of the sewage treatment cylinder 21 near the inlet pipe 22, completely covering the opening of the inlet pipe 22. After the sewage enters the sewage treatment cylinder 21, it will first be filtered by the sewage filter screen 25. Larger pollutants will be collected inside the sewage filter screen 25, while the treated water will pass through the sewage filter screen 25 into the sewage treatment cylinder 21 and then be discharged through the drain pipe 23.

[0038] The sewage filter screen 25 is equipped with a sewage pipe 26, which extends to the outside of the sewage treatment cylinder 21. When pollutants are treated, they will be discharged from the sewage pipe 26 under the pressure of water. When treating sewage, the sewage pipe 26 is in a closed state to prevent sewage from being discharged directly from the sewage pipe 26.

[0039] This device is mainly used for pretreatment of various sewage sources, to reduce the working pressure of large sewage treatment equipment, and for emergency treatment of sewage sources in case of emergencies. In case of emergency treatment, the corresponding chemical agent can be added into the sewage treatment tank 21, and the drain pipe 23 and the sewage discharge pipe 26 can be sealed respectively to treat the sewage through chemical reaction. Alternatively, only the basic filtration function can be used to pre-filter the sewage.

[0040] like Figure 3 As shown, in some embodiments, a gap is left between the outer surface of the sewage filter screen 25 and the inner wall of the sewage treatment cylinder 21. This gap is a drainage gap. The filtered water permeates from the gap between the sewage filter screen 25 and the sewage treatment cylinder 21 into the sewage treatment cylinder 21, and then is discharged from the drain pipe 23. When cleaning pollutants, clean water can be injected from the drain pipe 23. The clean water enters the interior of the sewage filter screen 25 through the gap between the sewage treatment cylinder 21 and the sewage filter screen 25, so that the pollutants in the sewage filter screen 25 are discharged from the drain pipe 26.

[0041] like Figure 3 As shown, in some embodiments, the sewage pipe 26 of this utility model is provided with a valve 27. The valve 27 is used to control the opening and closing of the sewage pipe 26. When treating sewage, the sewage pipe 26 is closed by the valve 27 to prevent sewage from being discharged directly from the sewage pipe 26, which would reduce the sewage treatment capacity. When cleaning pollutants later, the valve 27 can be opened to connect the sewage pipe 26 with the inside of the sewage filter screen 25, and the water flow can be backwashed by external pressure to the inside of the sewage filter screen 25, so that the dirt and water in the sewage filter screen 25 are discharged from the sewage pipe 26.

[0042] like Figure 3 As shown, in some embodiments, the drain pipe 23 of this utility model is provided with a pressure pump inlet pipe 24, which is connected to the inside of the drain pipe 23. When using clean water to backwash the sewage filter screen 25, a pressure pump can be connected through the pressure pump inlet pipe 24 to increase or decrease the pressure inside the sewage treatment cylinder 21, so that the water flow can flush with a stronger impact force. The pressure pump inlet pipe 24 is sealed when not in use.

[0043] like Figures 3-5 As shown, in some embodiments, the end of the sewage inlet pipe 22 on the inner wall of the sewage treatment cylinder 21 of this utility model is provided with a one-way valve 28. The valve body in the one-way valve 28 can move horizontally under pressure to control the opening and closing of the sewage inlet pipe 22.

[0044] Specifically, when the one-way valve 28 is pressurized from the side of the sewage inlet pipe 22, the inside of the sewage inlet pipe 22 is connected to the inside of the sewage treatment cylinder 21, so as to realize normal sewage injection;

[0045] The one-way valve 28 blocks the inside of the sewage inlet pipe 22 from the inside of the sewage treatment cylinder 21 from the pressurized side of the drain pipe 23, so as to prevent water from flowing back from the sewage inlet pipe 22 when flushing the inside of the sewage treatment cylinder 21 and the inside of the sewage filter screen 25.

[0046] like Figure 5 As shown, in some embodiments, the one-way valve 28 of this utility model includes a limiting guide cage 281. The limiting guide cage 281 has a cylindrical structure and several water-permeable grooves are provided on its outer surface. The limiting guide cage 281 is provided with a return spring 282 and a sealing plug 283. The return spring 282 applies elastic pressure to the sealing plug 283 from the side of the sewage inlet pipe 22 near the sewage inlet pipe 22. The sealing plug 283 can seal the opening of the sewage inlet pipe 22 and can slide inside the limiting guide cage 281. When sewage is transported from the sewage inlet pipe 22, the pressure of the sewage will push the sealing plug 283 to compress the return spring 282, so that the sewage inlet pipe 22 is connected to the inside of the sewage treatment cylinder 21. When the water pressure is greater than the pressure provided at the sewage inlet pipe 22, the sealing plug 283 will move towards the sewage inlet pipe 22 and close the sewage inlet pipe 22 under the combined action of water pressure and return spring 282.

[0047] like Figure 3 As shown, in some embodiments, the sealing plug 283 of this utility model consists of a circular platform and a circular plug shaft. The circular platform is used to abut against the return spring 282, while the circular plug shaft is used to block and seal the inside of the sewage inlet pipe 22. The outer surface of the circular platform is in close contact with the inner wall of the limiting guide cage 281 to improve the stability of the sealing plug 283 when it moves. The circular plug shaft can extend into the inside of the sewage inlet pipe 22 and be in close contact with the inner wall of the sewage inlet pipe 22 to improve the sealing performance when sealing the sewage inlet pipe 22.

[0048] like Figure 1 As shown, in some embodiments, the sludge collection mechanism 1 of this utility model includes a sludge collection box 11, which is a box structure. The top of the sludge collection box 11 is provided with an opening for sludge to enter. The bottom of the sludge collection box 11 is provided with a movable roller 13 to facilitate the movement of the entire device. Generally, the movable roller 13 can be set as a universal wheel. The sewage separation mechanism 2 is located above the sludge collection box 11 and is fixed.

[0049] like Figure 1 As shown, in some embodiments, a support beam 12 is provided at the top opening of the sludge collection tank 11 of this utility model, and a support leg 29 is provided on the outer surface of the sewage treatment cylinder 21. Through the cooperation of the support beam 12 and the support leg 29, the sewage separation mechanism 2 can be installed above the sludge collection tank 11. The support beam 12 and the support leg 29 are connected by fasteners such as bolts. After the fasteners are removed, the sludge collection mechanism 1 and the sewage separation mechanism 2 can be separated.

[0050] like Figure 1As shown, in some embodiments, there is a gap between the top of the sludge collection tank 11 and the outer surface of the sewage treatment cylinder 21, and the valve 27 is located in this gap, which allows the operator to easily operate the valve 27 during use.

[0051] In summary, the mobile decentralized sewage treatment equipment of this utility model, by setting up a sewage treatment cylinder 21, with an inlet pipe 22 and a drain pipe 23 at both ends of the sewage treatment cylinder 21 respectively, and a sewage filter screen 25 is set inside the sewage treatment cylinder 21 near the end of the inlet pipe 22, and a drain pipe 26 is set on the sewage filter screen 25 extending into the inside of the sewage collection mechanism 1, during sewage treatment, the sewage entering from the inlet pipe 22 is filtered by the sewage filter screen 25, the treated water is discharged through the drain pipe 23, and the dirt is discharged through the drain pipe 26. This device has a simple structure, is suitable for miniaturization, and is convenient for decentralized arrangement, thus achieving the effect of reducing the working pressure of sewage purification devices.

[0052] This invention features a one-way valve 28 inside the sewage treatment cylinder 21 and a pressure pump inlet pipe 24 on the drain pipe 23. When cleaning the equipment, the drain pipe 23 is closed, and a pressure pump is connected to the pressure pump inlet pipe 24 to pressurize and inject water into the sewage treatment cylinder 21. Under pressure, the one-way valve 28 closes the sewage inlet pipe 22, and the water flow impacts the surface of the sewage filter screen 25 under pressure and enters the interior of the sewage filter screen 25. When discharged through the sewage outlet pipe 26, the dirt can be flushed out of the device, achieving a convenient cleaning effect.

[0053] This utility model incorporates a sludge collection box 11 to collect treated sludge, preventing haphazard discharge of sludge. Furthermore, the bottom of the sludge collection box 11 is equipped with casters 13, making the entire device easy to move and enabling it to be moved to a sewage point for emergency sewage treatment.

[0054] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0055] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
