Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, and more specifically to an environmentally friendly wastewater treatment device for highway construction. Background Art

[0002] In the process of highway construction, the treatment of construction wastewater is a crucial link. Highway construction wastewater mainly comes from multiple construction links such as tunnel excavation, bridge construction, roadbed filling, concrete mixing, etc., which contains a large amount of suspended matter, sediment, grease, chemical additives and other pollutants. If these wastewaters are directly discharged into the natural environment, they will not only seriously pollute the soil and water bodies, but also have a long-term negative impact on the surrounding ecological environment. Therefore, scientifically and effectively treating highway construction wastewater and realizing its recycling is an urgent need for environmental protection.

[0003] With the increasingly stringent environmental regulations, the discharge standards for construction wastewater are constantly improving. Through the recycling of wastewater, we can reduce the pollution of natural water bodies, protect the ecological environment, and meet the requirements of sustainable development. Water resources are precious natural resources, especially in some areas where water resources are scarce. The recycling of construction wastewater can save a lot of fresh water resources and reduce construction costs. Wastewater recycling can not only reduce wastewater treatment costs, but also further reduce construction costs and improve economic benefits by recycling and reusing useful substances in wastewater (such as sand and gravel, concrete mixing water, etc.).

[0004] However, in existing wastewater environmental protection treatment devices, the clogging of porous plates is one of the common problems in the treatment devices. Since construction wastewater contains a large amount of suspended solids and particulate matter, the filter core plate is easily clogged and needs to be replaced frequently, which increases the operating cost and maintenance difficulty. As the degree of clogging of the filter core plate increases, the treatment effect will gradually decrease, affecting the quality of wastewater recycling. Traditional wastewater treatment devices usually consume a lot of electricity or water resources during the treatment process, which increases energy consumption and operating costs. Therefore, it is particularly important to design a wastewater treatment device that can be cleaned quickly and does not require disassembly of the porous plate for cleaning; in view of this, we propose a wastewater environmental protection treatment device for highway construction.

[0015] The present invention also provides a method for using a wastewater environmental protection treatment device for highway construction, comprising the following steps:

[0016] S1, pre-rinsing operation;

[0017] First, the driving mechanism drives the driving rod A to rotate, and the driving rod A drives the driving gear A at the bottom to rotate on the bearing top plate. When the driving gear A meshes with the inner wall teeth of the driving inner gear ring A to drive it to rotate, the driving inner gear ring A drives the rotating ring to rotate. The rotating ring makes a number of guide blocks move on the long holes and sliding holes of the fixed ring and the rotating ring to form an unfolded state, and then the water is transported into the wastewater treatment column through the water inlet pipe, and the pressure pump pressurizes the water to achieve positive flushing and wetting of the porous plate;

[0018] S2, soaking and descaling operation;

[0019] After the porous plate is rinsed and wetted, the cleaning agent is injected into the cleaning wipe block through the injection hole, the driving mechanism drives the driving rod B to rotate, the driving rod B drives the driving gear B to rotate, the driving gear B engages with the driving inner gear ring B to drive it to rotate, the driving inner gear ring B drives several driving gears B to rotate synchronously, the driving gear B engages with the driving rack to drive the cleaning wipe block to move on the slot, the cleaning agent in the injection hole penetrates the smear ball head through the inside of the cleaning wipe block, the smear ball head squeezes the cleaning agent onto the surface of the porous plate, and several uniform rollers make the cleaning agent evenly applied to the bottom of the porous plate, soaking the porous plate to soften scale, impurities, etc.;

[0020] S3, reverse flushing operation;

[0021] The driving mechanism drives the driving rod A to rotate, and the driving rod A drives the driving gear A at the bottom to rotate on the bearing top plate. When the driving gear A meshes with the inner wall teeth of the driving inner gear ring A to drive it to rotate, the driving inner gear ring A drives the rotating ring to rotate. The rotating ring enables a number of guide blocks to move on the long holes and sliding holes of the fixed ring and the rotating ring to form a recoil channel. The water body first contracts and then expands through the contraction body, throat and expansion body of the recoil channel. Based on the one-dimensional steady isentropic flow theory, the subsonic water flow is accelerated in the contraction section and continues to accelerate in the expansion section. The vortex groove opened thereon enables a rotating vortex to be generated when the fluid passes through. The vortex can penetrate into the tiny pores of the porous plate, increase the contact area between the fluid and the surface of the porous plate, and form a strong backwashing effect.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention improves the structure of the existing wastewater treatment device by arranging a vortex recoil mechanism at the bottom of the wastewater treatment column near the outlet pipe. The water in the outlet pipe is pumped into the bottom of the wastewater treatment column by a water pump. Since the recoil guide component of the vortex recoil mechanism is in the shape of a Laval tube, the water body first contracts and then expands. Based on the one-dimensional steady isentropic flow theory, the subsonic water flow is accelerated in the contraction section and continues to accelerate in the expansion section. During the backwashing process, the flow rate of the fluid flowing through the porous plate is significantly increased, and its pressure is reduced, thereby effectively improving the backwashing effect. The increase in flow rate helps to peel off the suspended solids deposited on the surface of the filter material, especially the dirt and impurities formed on the surface of the porous plate, which can ensure that the backwashing water flow has sufficient kinetic energy and impact force to more effectively remove these dirt and impurities.

[0024] 2. The present invention divides the guide block into a contraction body, a throat and an expansion body. The contraction body, the throat and the expansion body cooperate to form a whole and form a Laval tube with a plurality of whole bodies, and vortex grooves are provided on the inner wall in a circular shape at equal intervals. The vortex grooves enable rotating vortices to be generated when the fluid passes through. The vortices can penetrate into the tiny pores of the porous plate, thereby increasing the contact area between the fluid and the surface of the porous plate. The vortex not only has impact force, but also its rotational motion can peel off the stubborn dirt attached to the surface of the porous plate, thereby more effectively removing the dirt and impurities on the surface of the porous plate.

[0025] 3. The present invention arranges a carrier plate at the bottom end of the porous plate, and a cleaning wipe block is inserted on the carrier plate. The driving mechanism is connected through the driving rod B of the linkage assembly. The driving rod B drives the driving gear B to rotate, and the driving gear B engages with the driving inner gear ring B to drive it to rotate. The driving inner gear ring B drives several driving gears B to rotate synchronously. The driving gear B engages with the driving rack to drive the cleaning wipe block to move on the slot, so that the cleaning wipe block cleans the porous plate. Combined with the vortex water flow of the recoil guide assembly, the stubborn dirt on the surface of the porous plate is further peeled off, thereby improving the cleaning efficiency.

[0026] 4. The present invention provides a liquid injection hole at one end of the top of the cleaning wipe block, and injects the cleaning agent through the liquid injection hole. When the driving rod B drives the driving gear B to rotate, the driving gear B engages with the driving inner gear ring B to drive it to rotate, and the driving inner gear ring B drives several driving gears B to rotate synchronously, and the driving gear B engages with the driving rack to drive the cleaning wipe block to move on the slot, the cleaning agent in the liquid injection hole penetrates the smear ball head through the inside of the cleaning wipe block, and the smear ball head squeezes the cleaning agent to the surface of the porous plate, and several uniform rollers make the cleaning agent evenly smeared to the bottom of the porous plate, which is used to soften scale, impurities, etc., and the automatic smearing function reduces the steps of manually smearing the cleaning agent, reduces the difficulty of disassembly and assembly and the labor intensity. At the same time, cleaning is fast and efficient, saving the time cost of maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] like Figures 1 to 12 As shown, the present invention relates to an environmentally friendly wastewater treatment device for highway construction, comprising a support frame 1, a wastewater treatment column 2 is provided on the support frame 1, a water inlet pipe 3 is provided at the top of the wastewater treatment column 2, a pressure pump 4 is provided at the top of the wastewater treatment column 2 near the water inlet pipe 3, a water outlet pipe 5 is provided at the bottom of the wastewater treatment column 2, a water pump 10 is provided on the water outlet pipe 5, an eddy current recoil mechanism 6 is provided at one end of the wastewater treatment column 2 near the water outlet pipe 5, a porous plate 7 is provided at one end of the wastewater treatment column 2 near the water inlet pipe 3, a smearing mechanism 8 is provided at the bottom of the porous plate 7, and a driving mechanism 9 is provided between the smearing mechanism 8 and the eddy current recoil mechanism 6. The present invention improves the structure of the existing wastewater treatment device by setting a vortex recoil mechanism 6 at the bottom of the wastewater treatment column 2 near the outlet pipe 5. The water in the outlet pipe 5 is pressurized and pumped into the bottom of the wastewater treatment column 2 by a water pump 10. Since the recoil guide component 602 of the vortex recoil mechanism 6 is in the shape of a Laval tube, the water body first contracts and then expands. Based on the one-dimensional steady isentropic flow theory, the subsonic water flow is accelerated in the contraction section and continues to accelerate in the expansion section. During the backwashing process, the flow rate of the fluid flowing through the porous plate is significantly increased, and its pressure is reduced, thereby effectively improving the backwashing effect. The increase in flow rate helps to peel off the suspended solids deposited on the surface of the filter material, especially the dirt and impurities formed on the surface of the porous plate, which can ensure that the backwashing water flow has sufficient kinetic energy and impact force to more effectively remove these dirt and impurities.

[0050] In an embodiment of the present invention, the vortex recoil mechanism 6 includes a driving bearing assembly 601 and a recoil guide assembly 602. The driving bearing assembly 601 is arranged inside the wastewater treatment column 2 near the bottom of the driving mechanism 9, and the recoil guide assembly 602 is arranged inside the wastewater treatment column 2 near the bottom of the driving bearing assembly 601.

[0051] The driving bearing assembly 601 includes a bearing top plate 6011, a driving inner gear ring A6012, a driving gear A6013 and a driving rod A6014.

One end of the driving rod A6014 is connected to the top end of the driving rod A6014. The other end of the driving rod A6014 is connected to the driving mechanism 9. The top end of the recoil guide assembly 602 is connected to the bottom end of the driving inner gear ring A6012. The present invention sets a bearing top plate 6011 on the inner wall of the wastewater treatment column 2, and the driving mechanism 9 drives the driving rod A6014 to rotate.

The driving gear A6013 engages with the inner wall teeth of the driving inner gear ring A6012 to drive it to rotate. The driving inner gear ring A6012 drives the recoil guide component 602 at the bottom to expand and form a Laval tube shape. Based on the principle of the Laval tube, the flow state of the fluid in the recoil guide component 602 is optimized, and the friction between the fluid and the wall of the recoil guide component 602 is reduced. Therefore, the head loss during the backwashing process can be reduced, and the backwashing efficiency can be effectively improved.

The guide block 6022 is movably connected to the rotating ring 6021 and the fixed ring 6023 in an annular and equidistant manner. A plurality of guide blocks 6022 cooperate to form a recoil channel 6024. Long holes 6025 are provided in an annular and equidistant manner on the rotating ring 6021, and sliding holes 6026 are provided in an annular and equidistant manner on the fixed ring 6023.

When the driving gear A6013 is engaged with the inner wall teeth of the driving inner gear ring A6012 to drive it to rotate, the driving inner gear ring A6012 drives the rotating ring 6021 to rotate, and the rotating ring 6021 causes the plurality of guide blocks 6022 to move on the long holes 6025 and the sliding holes 6026 of the fixed ring 6023 and the rotating ring 6021 to form a recoil In channel 6024, water first contracts and then expands through the contraction body 6034, throat 6035 and expansion body 6036 of the recoil channel 6024. Based on the one-dimensional steady isentropic flow theory, the subsonic water flow is accelerated in the contraction section and continues to accelerate in the expansion section. The vortex groove 6037 opened thereon enables the generation of rotating vortices when the fluid passes through. The vortices can penetrate into the tiny pores of the porous plate 7, increase the contact area between the fluid and the surface of the porous plate 7, and form a strong backwashing effect.
