Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a mobile sewage purification device. Background Art

[0002] With the development of society and the enhancement of environmental protection awareness, sewage treatment technology has been widely used in various fields. However, in emergency rescue, post-disaster recovery, field operations and marginal areas, fast and efficient sewage treatment has become an important challenge. Existing mobile sewage purification devices have problems such as low integration and relatively simple functions in practical applications, resulting in unsatisfactory response speed and treatment efficiency in emergency situations.

[0003] Existing mobile sewage purification devices usually require individual assembly of each component, which not only increases the complexity of the device, but also reduces its overall stability and reliability. In scenarios such as emergency rescue and post-disaster recovery, time and efficiency are crucial, and the cumbersome assembly process of these devices will undoubtedly delay the best treatment time and affect the speed of emergency response. In addition, due to the lack of effective integration between the various components, the efficient transportation of the device is also difficult, further restricting its application in emergency situations.

[0004] The functions of existing mobile sewage purification devices are relatively simple, and they can usually only perform basic sewage filtration treatment, making it difficult to achieve efficient sewage purification and recycling. These devices have limited effects in treating pollutants such as suspended matter and sediment in sewage, and are difficult to meet the high-standard purification requirements in practical applications. Especially when faced with complex sewage components, the treatment capacity of existing devices is obviously insufficient, resulting in substandard quality of the purified sewage, which affects the recycling effect of sewage.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] See also Figure 1-10 A mobile sewage purification device includes a treatment box 1, in which a water inlet chamber 11, a flocculation chamber 12, a biological treatment chamber 13 and an assembly chamber 14 are provided. The water inlet chamber 11 is connected to the upstream of the flocculation chamber 12, the biological treatment chamber 13 is connected to the downstream of the flocculation chamber 12, and the assembly chamber 14 is open and arranged below the flocculation chamber 12.

[0042] It also includes a pre-filter component 2, a dosing component 3, a stirring component 4, and a blower 5. The pre-filter component 2 is installed in the water inlet chamber 11, the dosing component 3 and the stirring component 4 are installed upstream of the flocculation chamber 12, a sedimentation tank 131 is arranged at the bottom of the biological treatment chamber 13, a water filter chamber 132 is arranged inside the sedimentation tank 131, and retention holes are evenly opened on the top of the water filter chamber 132. The bottom of the sedimentation tank 131 is connected to a mud discharge pipe 133 arranged outside the water filter chamber 132, and the blower 5 is connected to the water filter chamber 132.

[0043] It also includes a water purifier 61 , an RO water purifier 62 , and a water storage tank 63 which are arranged in the assembly chamber 14 and connected in sequence, and the water filter chamber 132 is connected to the water inlet 112 of the water purifier 61 .

[0044] The mobile sewage purification device provided in the present application, wherein all functional components involved are assembled into each chamber of the treatment box 1, forming a complete unified device, which facilitates the overall movement of the sewage purification device while ensuring efficient treatment and purification of sewage.

[0045] The sewage to be treated is introduced into the water inlet chamber 11. Under the treatment of the pre-filter component 2, large particles of impurities contained in the sewage are intercepted to ensure efficient subsequent treatment of the sewage. At the same time, the pre-filter component 2 can automatically discharge the intercepted impurities.

[0046] The sewage in the water inlet chamber 11 is treated by the pre-filter component 2 and then enters the flocculation chamber 12. The flocculant is added to the upstream of the treatment box 1 by the dosing component 3, and under the continuous stirring action of the stirring component 4, the flocculant and the sewage are fully mixed, and the suspended matter in the sewage is flocculated and precipitated. The flocculated precipitate is deposited at the bottom of the flocculation chamber 12 for unified discharge, and the upper clear water layer is transported from the downstream of the flocculation chamber 12 to the biological treatment chamber 13.

[0047] By adding microorganisms, nutrient solution and regulator into the biological treatment chamber 13, the blower 5 introduces external air into the biological treatment chamber 13 through the water filter chamber 132, and uses microorganisms to degrade organic matter in the sewage to eventually generate sludge precipitation. The purified water is filtered through the interception hole at the top of the water filter chamber 132, and then enters the water purification adsorber 61. The water purification adsorber 61 uses activated carbon adsorption to adsorb volatile substances or gases in the water, and then is treated by the RO water purifier 62. The water is forced to pass through a semi-permeable membrane under high pressure, so that water molecules pass through the membrane, while solutes (such as salts, residual organic matter, etc.) are retained on the other side of the membrane, achieving a water purification effect and finally stored in the water storage tank 63.

[0048] In order to facilitate the unified installation of sewage purification devices and control the movement of sewage purification devices to meet the needs of emergency rescue, post-disaster recovery, field operations, sewage treatment in marginal areas and recycling, the following technical solutions are provided.

[0049] The vehicle further comprises a traction frame 7 , on which the processing box 1 is fixedly mounted.

[0050] A connecting piece is provided on the front side of the traction frame 7 to achieve effective connection with the traction vehicle. The traction vehicle drives the traction frame 7 and the treatment box 1 installed thereon and the functional components assembled in the treatment box 1 to move stably to cope with emergency rescue, post-disaster recovery, field operations, and sewage treatment work in marginal areas.

[0051] A generator, usually a diesel generator, can also be installed in the assembly cavity 14 of the traction frame 7 or the treatment box 1. The diesel generator generates electricity to provide stable power to various functional components that consume electricity, ensuring the stable operation of the sewage purification device in a field environment where there is a lack of power supply.

[0052] In order to ensure that the pre-filter assembly 2 is stably assembled in the water inlet chamber 11 and to achieve filtering of input sewage and discharge of retained impurities, the following technical solution is provided.

[0053] The pre-filter assembly 2 includes a filter grid plate 21, a mounting shaft 22, a spiral conveying blade 23, and a driving motor A24. The filter grid plate 21 is fixedly installed in the water inlet chamber 11 and is arranged obliquely. The top of the water inlet chamber 11 is connected to a sewage pipe 111 arranged below the filter grid plate 21. The bottom of the water inlet chamber 11 is provided with a water inlet 112 that is connected to the flocculation chamber 12. An arc-shaped sink 113 is provided in the water inlet chamber 11. The arc-shaped sink 113 is arranged at the bottom of the filter grid plate 21. The mounting shaft 22 is rotatably installed in the water inlet chamber 11 and is arranged concentrically with the arc-shaped sink 113. The spiral conveying blade 23 is fixedly installed on the periphery of the mounting shaft 22, and the spiral conveying blade 23 includes two groups arranged in opposite spiral directions. A vertically downwardly arranged impurity discharge pipe 114 is connected to the center of the arc-shaped sink 113. A valve A1141 is installed at the bottom of the impurity discharge pipe 114. The driving motor A24 is fixedly installed on the outside of the treatment box 1 and is poweredly connected to the mounting shaft 22.

[0054] The sewage to be treated is input into the water inlet chamber 11 from the sewage connecting pipe 111. The sewage can pass through the filter grating 21 and be input into the flocculation chamber 12 through the water inlet 112. The impurities contained therein can be intercepted by the filter grating 21. Since the filter grating 21 is arranged at an angle, the intercepted impurities enter the arc-shaped trough 113 under the action of gravity and are collected. After the impurities in the arc-shaped trough 113 are fully collected, the input of the sewage tank water inlet chamber 11 is disconnected, and the valve A1141 is opened.

[0055] The driving motor A24 drives the installation shaft 22 and the two sets of spiral conveying blades 23 arranged oppositely thereon to operate, so as to convey the debris in the arc-shaped trough 113 from both ends of the arc-shaped trough to the center, and then discharge it outward through the debris discharge pipe 114.

[0056] In order to ensure that the driving motor A24 can be stably installed outside the processing box 1, a mounting bracket A is fixedly connected to the outer wall of the processing box 1, and the driving motor A24 is fixedly installed on the mounting bracket A.

[0057] In order to ensure that the dosing component 3 can be stably assembled in the flocculation chamber 12, ensure that the flocculation chamber 12 can flocculate and settle the sewage, ensure that the sewage output from the downstream end of the flocculation chamber 12 does not contain sediment, and facilitate the discharge of the sediment, the following technical solution is provided.

[0058] The dosing assembly 3 includes a spray pipe 31, a medicine storage box 32, and a pressure pump A33. The spray pipe 31 is fixedly installed on the top upstream of the flocculation chamber 12. The medicine storage box 32 is connected to the spray pipe 31 through a medicine supply pipe 34, and the pressure pump A33 is assembled on the medicine supply pipe 34.

[0059] A sedimentation tank 121, a slope section 122, and a horizontal section 123 are arranged in sequence from upstream to downstream at the bottom of the flocculation chamber 12. The slope section 122 gradually rises from the upstream to the downstream of the flocculation chamber 12. A sewage pipe 124 is connected to the bottom of the sedimentation tank 121, and a valve B1241 is installed on the sewage pipe 124.

[0060] The medicine storage box 32 and the pressure pump A33 are fixedly installed on the top of the treatment box 1 to ensure that the two are stably installed. When the pressure pump A33 is working, it can transport the flocculant stored in the medicine storage box 32 to the spray pipe 31, and the spray pipe 31 evenly sprays the flocculant to the upstream of the flocculation chamber 12 to fully mix with the sewage input into the flocculation chamber 12.

[0061] The flocculant is mixed with sewage to form flocculated sediments from the suspended matter, which are finally deposited at the bottom of the flocculation chamber 12. The orderly slope section 122 is arranged so that the sediment can fall into the sedimentation tank 121 under the action of gravity. When the sedimentation tank 121 is full, the valve B1241 can be opened to discharge the sediment through the sewage pipe 124. The horizontal section 123 is arranged to ensure that the clean water after flocculation treatment flows smoothly at the downstream of the flocculation chamber 12.

[0062] In order to ensure that the stirring component 4 can be stably installed in the flocculation chamber 12, to fully mix the sewage and flocculant input therein and accelerate the sedimentation, and to avoid affecting the smooth flow of the downstream water flow when the stirring component 4 is in operation, the following technical solution is provided.

[0063] The stirring assembly 4 includes a mounting plate 41, an outer stirring blade 42, a stirring shaft 43, an inner stirring blade 44, and a driving motor B45. The mounting plate 41 includes two groups of outer stirring blades 42 that are rotatably mounted on the inner side of the flocculation chamber 12 and are arranged concentrically. A plurality of groups of evenly arranged outer stirring blades 42 are fixedly connected between the two groups of mounting plates 41. The stirring shaft 43 is rotatably mounted on the axis of the mounting plate 41. The inner stirring blades 44 are evenly fixed to the stirring shaft 43, and the inner stirring blades 44 are arranged on the inner side of the outer stirring blades 42. The driving motor B45 is fixedly mounted on the outer side of the processing box 1, and A driving bevel gear 451 is fixedly connected to the output shaft of the driving motor B45, and a transmission bevel gear A411 and a transmission bevel gear B431 arranged on the outside of the processing box 1 are respectively fixedly connected to the mounting plate 41 and the stirring shaft 43. The transmission bevel gears A411 and B431 are symmetrically arranged, and the driving bevel gear 451 is meshed with the transmission bevel gears A411 and B431. A plurality of isolation plates 125 arranged in the vertical direction are also fixedly connected to the flocculation chamber 12, and the isolation plates 125 are arranged above the slope section 122.

[0064] The stirring assembly 4 is arranged at the position of the water inlet 112 and is directly below the spray pipe 31. A mounting bracket B is fixedly connected to the outside of the processing box 1, and the drive motor B45 is fixedly installed on the mounting bracket B to ensure that the drive motor is stably installed outside the processing box 1.

[0065] When the driving motor B45 drives the driving bevel gear 451 to operate, since the transmission bevel gear A411 and the transmission bevel gear B431 are arranged symmetrically, they can drive the transmission bevel gear A411 and the transmission bevel gear B431 to operate in the reverse direction, and then drive the outer stirring blades 42 and the inner stirring blades 44 to operate in the reverse direction. The outer stirring blades 42 and the inner stirring blades 44 operating in the reverse direction at high speed can fully mix the sewage and the flocculant, thereby accelerating the flocculation and sedimentation of the sewage.

[0066] When the stirring assembly 4 is running, it can drive the sewage in the flocculation chamber 12 to generate vortex and turbulence. By adding the isolation plate 125, the vortex and turbulence can be blocked from transmitting to the downstream of the flocculation chamber 12, ensuring that the sewage in the slope section 122 and the downstream flows slowly, making it convenient for the generated flocculation precipitation to be deposited at the bottom of the flocculation chamber 12.

[0067] In order to ensure that the sewage downstream of the flocculation chamber 12 can be stably transported to the biological treatment chamber 13, to ensure the stability of the air pressure in the biological treatment chamber 13, and to facilitate the addition of mixed liquids such as microorganisms, nutrient solution, regulators, etc. into the biological treatment chamber 13, the following technical solution is provided.

[0068] An overflow port 126 is provided at the downstream of the flocculation chamber 12, and a water collecting cover 1261 is installed at the overflow port 126. A water inlet pipe 134 is connected to the top of the biological treatment chamber 13, and the water collecting cover 1261 is connected to the water inlet pipe 134 through a water pipe 1262. A dosing pipe 135 and a pressure relief pipe 136 are also connected to the top of the biological treatment chamber 13. A sealing cover 1351 is installed on the dosing pipe 135, and a pressure stabilizing valve 136 is installed on the pressure relief pipe 136. The mud discharge pipe 133 extends to the outside of the treatment box 1, and a valve C1331 is installed on the mud discharge pipe 133.

[0069] The sewage after flocculation and sedimentation in the flocculation chamber 12 is input into the biological treatment chamber 13 along the overflow port 126, the water collecting cover 1261, the water pipe 1262, and the water inlet pipe 134, and microorganisms, nutrient solution, and regulator (to adjust the pH value of sewage) are added into the biological treatment chamber 13 through the dosing pipe 135. The blower 5 pressurizes the external air and transports it to the water filter chamber 132, and passes it into the biological treatment chamber 13 through the interception hole at the top of the water filter chamber 132, so as to achieve the aeration effect of the sewage in the biological treatment chamber 13. After the air pressure in the biological treatment chamber 13 increases, the excess gas can be discharged through the pressure regulating valve 1361, so as to cause the biological treatment chamber 13 to explode. At the same time, the sludge attached to the outer side of the top of the water filter chamber 132 can be blown away during the aeration process to prevent the sludge from clogging the interception hole and affecting the subsequent filtration effect of the sewage.

[0070] Microorganisms can decompose organic matter in sewage and generate sludge which is deposited in the sedimentation tank 131. When the sedimentation tank 131 is full of sludge, the valve C1331 can be opened to discharge the sludge along the sludge discharge pipe 133. The sewage treated by microorganisms can enter the water filter chamber 132 through the interception hole, and finally enter the water purification adsorber 61 and the RO water purifier 62 in sequence for further treatment.

[0071] In order to ensure that the pressurized air of the blower 5 can be stably input into the water filter chamber 132, ensure that the sewage filtered in the water filter chamber 132 can be stably input into the water purification adsorber 61, and avoid interference between air and sewage, the following technical solution is provided.

[0072] A booster pump B64 is fixedly installed on the water tank 63, and the booster pump B64 is connected to the water purification adsorber 61. A connecting pipe 1321 is connected to the bottom of the water filter chamber 132, and the connecting pipe 1321 is connected to the booster pump B64 through a connecting pipe 81. The connecting pipe 81 is connected to an air supply pipe 82 that is connected to the blower 5. The air supply pipe 82 is equipped with an electric valve A821, and the connecting pipe 81 is equipped with an electric valve B811 arranged between the air supply pipe 82 and the booster pump B64.

[0073] When aerating the biological treatment chamber 13, the electric valve A821 is controlled to be in an open state, and the electric valve B811 is controlled to be in a closed state. When the blower 5 is working, the external air is pressurized and transported to the water filter chamber 132 through the air supply pipe 82 and the connecting pipe 81.

[0074] When the sewage in the biological treatment chamber 13 is filtered, collected and transmitted to the water purification adsorber 61, the electric valve A821 is controlled to be in a closed state, and the electric valve B811 is controlled to be in an open state. The sewage entering the water filtration chamber 132 can be stably transported to the water purification adsorber 61 along the connecting pipe 81 under the pressurized action of the pressure pump B64.
