Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to a device and method for treating wastewater produced by environmentally friendly concrete components. Background Art

[0002] During the production of concrete components, mixing equipment (such as mixers) needs to be cleaned regularly. After each mixing operation, a large amount of concrete slurry will remain inside the equipment. In order to ensure the normal operation of the equipment and the quality of the next mixing, the equipment needs to be rinsed with water. These rinse waters contain cement, sand and gravel particles, admixtures and other ingredients. Concrete prefabricated components need to be cured after production to ensure the normal development of their strength and quality. During the watering curing process, some water will flow away some soluble components in the concrete, such as calcium hydroxide. If these curing wastewaters are not treated, they will also pollute the environment. In addition, some raw materials of concrete may contain a small amount of grease. For example, some poor quality sand and gravel may be contaminated during mining or transportation and contaminated with a small amount of oil. In addition, in some cases where recycled materials (such as recycled aggregates) are used, these recycled materials may contain residual grease. When these raw materials are mixed with water, grease will enter the wastewater of concrete component production.

[0003] At present, traditional wastewater treatment methods mainly include physical sedimentation, chemical flocculation and biodegradation. The physical sedimentation method has limited treatment effect and is difficult to remove fine particles and soluble organic matter; although the chemical flocculation method can remove some organic matter, it may cause secondary pollution; the biodegradation method has a long treatment cycle and is not effective for difficult-to-degrade organic matter. In addition, the existing technology is not ideal in removing grease from wastewater, and the equipment is complex and the operating cost is high. For this reason, the present invention provides a device and method for treating environmentally friendly production wastewater of concrete components. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides an environmentally friendly concrete component production wastewater treatment device and method, which can efficiently remove grease and organic matter in the wastewater, has the characteristics of low-cost operation, and reduces the risk of secondary pollution.

[0005] The present invention provides the following technical solution: a concrete component environmentally friendly production wastewater treatment device, comprising a treatment box and a feed inlet and a drain outlet opened at the top and bottom of the treatment box, wherein a stirring structure is arranged inside the treatment box, and the stirring structure is driven by a motor;

[0006] Two oil suction devices for absorbing grease are installed on the top of the treatment box, and the oil suction devices are driven by the driving stirring structure. The oil suction devices extend into the treatment box to absorb grease in the sewage, and the oil suction devices simultaneously drip defoaming agent into the sewage to reduce bubbles on the surface of the sewage;

[0007] Four groups of magnetic pistons are provided at the bottom of the treatment box, and the magnetic pistons extend from the bottom of the treatment box and are connected to the inflation system. The operation of the magnetic pistons causes the inflation system to blow air into the treatment box from above and below the sewage to accelerate the degradation of the sewage. At the same time, the bubbles will drive the oil to float up and be absorbed by the oil absorption device, and the foam on the surface of the sewage is eliminated by the blown air.

[0008] The stirring structure includes a stirring shaft and several groups of stirring blades installed on the stirring shaft, and a magnetic fan for driving the magnetic piston to move is installed at the bottom of the stirring shaft.

[0009] Preferably, the stirring structure also includes four sets of fixed frames installed inside the processing box, and several sets of diverter rods with triangular cross-sections are installed on the fixed frames, and the stirring blades are located between the diverter rods. The bottom end of the stirring shaft is connected to the four sets of fixed frames through a stabilizing frame, and the stirring shaft is rotatably connected to the stabilizing frame.

[0010] Preferably, the oil suction device includes two L-shaped side panels installed on the top of the treatment box, and the side panels extend into the interior of the treatment box, four conveying rollers are installed on the two side panels, and the four conveying rollers are provided with transmission belts, the belts are L-shaped for transmission, and a layer of oil-absorbing felt is laid on the surface of the belt. The oil suction device also includes a transmission shaft connected to the front end conveying roller of the belt, and the transmission shaft is driven by a bevel gear and a stirring shaft. Under the linkage of the transmission shaft, the conveying roller drives the belt transmission, so that the oil-absorbing felt absorbs grease on the surface of the sewage during the transmission process.

[0011] Preferably, the oil suction device also includes two water-absorbing materials installed on the belt, and the two water-absorbing materials are distributed on both sides of the oil-absorbing felt, a liquid collecting tank and a guide roller located in the liquid collecting tank are installed between the two side plates, the belt is introduced into the liquid collecting tank through the guide roller, so that the water-absorbing material adheres to the defoaming agent, and extrusion wheels for squeezing the water-absorbing material are installed on the inner side of the bottom of the two side plates, and the defoaming agent is squeezed out by the extrusion wheels and introduced into the sewage.

[0012] Preferably, the oil suction device also includes a squeezing roller installed at the head end of the belt, and the squeezing roller and the end surface of the conveying roller driven by the driving shaft are driven by gear meshing, so that the squeezing roller and the conveying roller jointly squeeze the oil-absorbing felt to squeeze out the grease therein, and the head ends of the two side plates are equipped with oil collecting troughs located below the squeezing rollers, and the grease dripping from the squeezing rollers falls into the oil collecting troughs, and the side plates are provided with oil discharge ports for connecting to the oil collecting troughs.

[0013] Preferably, the inflation system includes a sleeve connected to the bottom of the magnetic piston, a one-way valve A and a one-way valve B for gas conduction, the one-way valve B is connected to a loop pipe installed on the side wall of the treatment box through a pipeline, and a nozzle extending to the inside of the treatment box is installed at the top of the loop pipe, and a one-way valve C is also installed at the top of the loop pipe, and an exhaust pipe extending downward to is installed at the other end of the one-way valve C, and the bottom end of the exhaust pipe extends to the inside of the treatment box. When the magnetic piston is in operation, air enters through the one-way valve A and is discharged from the one-way valve B, a part of the air in the loop pipe is introduced into the sewage surface through the nozzle, and another part of the air in the loop pipe is introduced into the exhaust pipe through the one-way valve C, and is introduced into the sewage from the bottom of the treatment box through the exhaust pipe.

[0014] Preferably, the magnetic piston includes a piston sleeve extending from the bottom of the processing box, and positioning rings are installed on the inner sides of the top and bottom ends of the piston sleeve, a piston that can slide up and down is provided inside the piston sleeve, a magnet is installed on the top of the piston, and the magnets embedded in two adjacent blades on the magnetic fan have opposite poles, when the magnetic fan passes the top of the piston sleeve, the piston slides up and down in the piston sleeve under the action of the magnetic force, the air pressure is changed to open the A check valve and the B check valve, so that air is sucked in and out.

[0015] Preferably, when the fan blades with the negative pole embedded in the magnetic fan and facing downward pass through the piston sleeve, the suction force of the positive and negative poles of the magnet will cause the piston to move upward, thereby reducing the air pressure in the piston sleeve. The reduced air pressure will cause the A one-way valve to open, sucking outside air into the piston sleeve to allow air to be introduced. When the fan blades with the positive pole embedded and facing downward pass through the piston sleeve, the repulsive force between the magnets with the same poles will cause the piston to move downward, thereby increasing the air pressure in the piston sleeve. The increased air pressure will cause the B one-way valve to open and discharge the air.

[0016] A method for using a concrete component environmentally friendly production wastewater treatment device, the specific operation is as follows:

[0017] S1. After the wastewater enters the treatment box through the feed port, the motor drives the stirring structure to stir the wastewater. At the same time, the magnetic fan on the stirring structure drives the magnetic piston to run after passing through the magnetic piston, so that the magnetic piston blows air into the treatment box through the inflation system, and introduces air from the bottom of the wastewater for aeration and from the surface of the wastewater for ventilation to eliminate foam. The stirring structure stirs and diffuses, and the bubbles drive the grease in the wastewater to float up, and the oxygen in the air accelerates the decomposition of substances in the wastewater and accelerates the aeration treatment;

[0018] S2. The stirring structure is driven while the oil absorption device is driven to absorb the grease floating on the surface of the wastewater, and the absorbed grease is squeezed out, and a defoaming agent is added to the wastewater to reduce the foam on the surface of the wastewater, thereby completing the grease separation treatment in the wastewater.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The design of the stirring structure helps to optimize the fluid flow path, reduce fluid turbulence, make the wastewater flow more stable, improve the mass transfer efficiency, further promote the decomposition and treatment of substances in the wastewater, and at the same time improve the stability of the stirring shaft. In addition, the stirring shaft drives the stirring blades to stir the wastewater, so that the air bubbles in the wastewater are evenly dispersed. The bubbles drive the oil in the wastewater to float to the water surface, which is convenient for the oil absorption device to adsorb and separate, thereby improving the efficiency of oil removal;

[0021] (2) The belt surface of the oil suction device is paved with oil absorption felt, which will drive the oil absorption felt to absorb the grease on the surface of the sewage during the belt transmission process. Then, the grease in the oil absorption felt will be squeezed out by the belt, which is convenient for collecting the grease and also convenient for the oil suction device to circulate and remove the oil from the wastewater, thus improving the sustainability of grease removal. At the same time, defoaming agent can also be added to the sewage to reduce the foam in the sewage.

[0022] (3) The magnetic piston interacts with the magnetic fan, and the magnetic piston acts with the inflation system to blow air into the treatment box. The air is divided into two parts. One part is introduced into the wastewater, which accelerates the decomposition of organic matter and drives the grease to float, thereby improving the efficiency of wastewater treatment.

DETAILED DESCRIPTION

[0033] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of known functions and known components to avoid unnecessary confusion of the concepts of the present invention.

[0034] See also Figure 1 and Figure 2 , a concrete component environmental protection production wastewater treatment device, including the following mechanisms:

[0035] The processing box 1 has a feed inlet 6 and a drain outlet 2 at its top and bottom, respectively, to facilitate the discharge of wastewater.

[0036] The stirring structure 3 is located inside the treatment box 1 and is driven by a motor to stir the wastewater.

[0037] The oil absorption device 4 is installed on the top of the treatment box 1 to absorb the grease in the sewage and is driven by the stirring structure 3.

[0038] The magnetic piston 5 is arranged at the bottom of the treatment box 1 and is used to blow in air and stir the sewage to accelerate the degradation treatment of the sewage.

[0039] The inflation system 7 is connected to the magnetic piston 5. When the magnetic piston 5 moves, it drives the inflation system 7 to pump air, and introduces air into the sewage for aeration and ventilation of the sewage liquid surface.

[0040] See also Figure 3A stirring structure 3 is installed inside the treatment box 1, and the stirring structure 3 includes a stirring shaft 31 and a plurality of stirring blades 32 installed on the stirring shaft 31, and a magnetic fan 33 for driving the magnetic piston 5 to move is installed at the bottom of the stirring shaft 31, so that the stirring shaft 31 rotates, driving the stirring blades 32 to stir the wastewater, and the magnetic fan 33 drives the magnetic piston 5 to operate, so that the magnetic piston 5 introduces air into the wastewater, and the air bubbles in the wastewater are stirred and dispersed evenly by the stirring blades 32, and the bubbles drive the grease in the wastewater to float to the water surface, which is convenient for the oil suction device 4 to adsorb and separate.

[0041] The stirring structure 3 also includes four sets of fixing frames 34 installed inside the treatment box 1, and a plurality of sets of diverter rods 35 with triangular cross-sections are installed on the fixing frames 34. The stirring blades 32 are located between the diverter rods 35. The triangular cross-sectional design of the diverter rods 35 helps to optimize the fluid flow path, reduce fluid turbulence, make the wastewater flow more stable, and improve the mass transfer efficiency.

[0042] The bottom end of the stirring shaft 31 is connected to the four sets of fixed frames 34 through a stabilizing frame 36, and the stirring shaft 31 is rotatably connected to the stabilizing frame 36. The stabilizing frame 36 improves the stability of the stirring shaft 31 to ensure that the stirring shaft 31 will not deviate or vibrate during the stirring process, thereby improving the durability and reliability of the equipment.

[0043] See also Figure 4 Two oil suction devices 4 for absorbing grease are installed on the top of the treatment box 1, and the oil suction device 4 extends into the treatment box 1. The oil suction device 4 includes two L-shaped side panels 41 installed on the top of the treatment box 1, and the side panels 41 extend into the treatment box 1. Four conveying rollers 42 are installed on the two side panels 41, and a transmission belt 43 is provided on the four conveying rollers 42. The belt 43 is L-shaped for transmission. A layer of oil-absorbing felt 44 is laid on the surface of the belt 43. The oil suction device 4 also includes a transmission shaft 48 connected to the front end conveying roller 42 of the belt 43, and the transmission shaft 48 is driven by the bevel gear 49 and the stirring shaft 31. Under the linkage of the transmission shaft 48, the conveying roller 42 drives the belt 43 to transmit, so that the oil-absorbing felt 44 absorbs grease on the surface of the sewage during the transmission process.

[0044] Under the meshing of the bevel gear 49, the stirring shaft 31 drives the transmission shaft 48, and the transmission shaft 48 drives a conveying roller 42 to rotate. The conveying roller 42 drives the belt 43 to transmit, and the belt 43 extends into the wastewater. Therefore, during the transmission process of the belt 43, the oil-absorbing felt 44 will be driven to absorb the grease on the surface of the sewage. The oil-absorbing felt 44 has the characteristics of absorbing oil but not water, so it can absorb a large amount of grease and is transmitted along with the transmission belt 43. Under the operation of the magnetic piston 5, the grease in the wastewater is driven by bubbles to float up and float on the liquid surface, which is convenient for the oil absorption device 4 to absorb, and the stirring structure 3 is stirred to make the liquid surface flow, and the grease is captured and absorbed by the oil-absorbing felt 44.

[0045] The oil absorption device 4 also includes two water-absorbing materials 410 installed on the belt 43, and the two water-absorbing materials 410 are distributed on both sides of the oil absorption felt 44. A liquid collecting tank 411 and a guide roller 412 located in the liquid collecting tank 411 are installed between the two side plates 41. The belt 43 is introduced into the liquid collecting tank 411 through the guide roller 412, so that the water-absorbing material 410 is adhered to the defoaming agent. The inner side of the bottom of the two side plates 41 is installed with an extrusion wheel 413 for squeezing the water-absorbing material 410. The defoaming agent is squeezed out and introduced into the sewage by the extrusion wheel 413. The belt 43 drives the two water-absorbing materials 410 to pass through the liquid collecting tank 411, and the adhered defoaming agent is transmitted to mix the defoaming agent with the sewage. When the belt 43 drives the two water-absorbing materials 410 to pass through the extrusion wheel 413, they are squeezed, so that the defoaming agent is led out and diffused in the sewage, and the foam on the sewage is cleaned by the defoaming agent.

[0046] A pipeline for adding defoaming agent is installed on the outside of the liquid collecting tank 411, and the pipeline is led out from the side plate 41. The defoaming agent is added to the liquid collecting tank 411 through the pipeline to facilitate the use of the oil suction device 4.

[0047] The oil suction device 4 also includes a squeezing roller 45 installed at the head end of the belt 43. The squeezing roller 45 and the end surface of the conveying roller 42 driven by the driving shaft are driven by gear meshing, so that the squeezing roller 45 and the conveying roller 42 squeeze the oil-absorbing felt 44 together to squeeze out the grease therein. The head ends of the two side plates 41 are equipped with oil collecting grooves 46 located below the squeezing rollers 45, and the grease dripping from the squeezing rollers 45 falls into the oil collecting grooves 46. The side plates 41 are provided with oil discharge ports 47 for connecting to the oil collecting grooves 46. Under the meshing of gears, the squeezing roller 45 contacts the conveying roller 42 and squeezes the oil-absorbing felt 44 to squeeze out the grease therein, and the dripping grease falls into the oil collecting tank 46 and is discharged through the oil discharge port 47, so that it is convenient to collect the grease and it is also convenient for the oil-absorbing device 4 to circulate and remove oil from the wastewater. In the squeezing process, the sewage on the water-absorbing material 410 can also be squeezed out, so that the water in the water-absorbing material 410 can be discharged, so that the defoaming agent can be adsorbed through the liquid collecting tank 411 and the defoaming agent can be added to the sewage.

[0048] See also Figure 5 Four groups of magnetic pistons 5 are provided at the bottom end of the processing box 1 , and the magnetic pistons 5 extend from the bottom end of the processing box 1 and are connected to the inflation system 7 .

[0049] See also Figure 6 The magnetic piston 5 includes a piston sleeve 51 led out from the bottom of the treatment box 1, and a positioning ring 52 is installed on the inner side of the top and bottom ends of the piston sleeve 51. A piston 53 that can slide up and down is arranged inside the piston sleeve 51. A magnet is installed on the top of the piston 53, and the magnets embedded in two adjacent blades on the magnetic fan 33 have opposite magnetic poles. When the magnetic fan 33 passes through the top of the piston sleeve 51, the piston 53 slides up and down in the piston sleeve 51 under the action of the magnetic force, and the air pressure is changed to open the A check valve 72 and the B check valve 73 to inhale and export air. At the same time, the piston 53 that moves up and down can stir the sewage and accelerate the aeration process.

[0050] The inflation system 7 includes a sleeve 71 connected to the bottom of the magnetic piston 5, the piston sleeve 51 is connected to the bottom of the sleeve 71, and a one-way valve A 72 and a one-way valve B 73 are used for gas conduction. The one-way valve B 73 is connected to a loop pipe 74 installed on the side wall of the treatment box 1 through a pipeline, and a nozzle 75 extending to the inside of the treatment box 1 is installed at the top of the loop pipe 74. A one-way valve C 76 is also installed at the top of the loop pipe 74. The other end of the one-way valve C 76 is installed with an exhaust pipe 77 extending downward, and the bottom end of the exhaust pipe 77 extends to the inside of the treatment box 1. When the magnetic piston 5 is in operation, air enters through the one-way valve A 72 and is discharged from the one-way valve B 73. A part of the air in the loop pipe 74 is introduced into the sewage surface through the nozzle 75, and another part of the air in the loop pipe 74 is introduced into the exhaust pipe 77 through the one-way valve C 76, and is introduced into the sewage from the bottom of the treatment box 1 through the exhaust pipe 77.

[0051] The design of the C check valve 76 can prevent the sewage inside the treatment box 1 from being introduced into the exhaust pipe 77, and a part of the air is discharged through the nozzle 75, so that the nozzle 75 sprays the foam on the surface of the sewage, accelerates the air flow, and quickly degrades the foam. The design of the C check valve 76 and the exhaust pipe 77 allows another part of the air to be introduced into the sewage for aeration.

[0052] When the fan blade with the negative pole embedded in the magnetic fan 33 passes through the piston sleeve 51, the suction force of the positive and negative poles of the magnet will cause the piston 53 to move upward, so that the air pressure in the piston sleeve 51 becomes smaller. The smaller air pressure will cause the A check valve 72 to open, and the outside air will be sucked into the piston sleeve 51 to allow air to be introduced. When the fan blade with the positive pole embedded in the magnetic fan 33 passes through the piston sleeve 51, the repulsive force between the magnets with the same poles will cause the piston 53 to move downward, so that the air pressure in the piston sleeve 51 becomes larger. The larger air pressure will cause the B check valve 73 to open and discharge the air.

[0053] In order to make the magnet generate a larger magnetic force, it is more appropriate to use a rubidium magnet, and the rotation speed of the stirring structure 3 is slow, so that the adsorption force and repulsion force between the rubidium magnets can drive the piston 53 to slide up and down.

[0054] See also Figure 7 When the fan blade with the negative pole facing downward inlaid on the magnetic fan 33 passes through the piston sleeve 51, the suction force of the positive and negative poles of the magnet will cause the piston 53 to move upward, so that the air pressure in the piston sleeve 51 becomes smaller, and the B check valve 73 is a one-way channel for exhaust and therefore cannot be conducted. The decrease in air pressure will cause the A check valve 72 to open, and the outside air will be sucked into the piston sleeve 51.

[0055] See also Figure 8 When the fan blade with the positive pole facing downward on the magnetic fan 33 passes through the piston sleeve 51, the repulsive force between the magnets with the same poles will cause the piston 53 to move downward, so that the air pressure in the piston sleeve 51 increases, and the A check valve 72 is a one-way channel for air intake and therefore cannot be conducted. The increase in air pressure will cause the B check valve 73 to open, and introduce air into the loop pipe 74. Part of the air in the loop pipe 74 is introduced into the sewage surface through the nozzle 75, and the other part of the air in the loop pipe 74 is introduced into the exhaust pipe 77 through the C check valve 76, and is introduced into the sewage from the bottom of the treatment box 1 through the exhaust pipe 77, completing the two operations of eliminating foam and aeration.

[0056] It is best to have four blades on the magnetic fan 33, and the four groups of magnetic pistons 5 are distributed equidistantly in a cross shape, so that the four blades on the magnetic fan 33 just correspond to the four groups of magnetic pistons 5. During the rotation of the magnetic fan 33, the blades of different magnetic poles will repeatedly pass through the four groups of magnetic pistons 5, causing the pistons 53 in the four groups of magnetic pistons 5 to move up and down repeatedly, thereby realizing the function of blowing air into the wastewater in the treatment box 1 for aeration.

[0057] A method for using a concrete component environmentally friendly production wastewater treatment device, the specific operation is as follows:

[0058] S1. After the wastewater enters the treatment box 1 through the feed port 6, the stirring structure 3 is driven by the motor to stir the wastewater. At the same time, the magnetic fan 33 on the stirring structure 3 drives the magnetic piston 5 to operate after passing through the magnetic piston 5, so that the magnetic piston 5 blows air into the treatment box 1 through the inflation system 7, and introduces air from the bottom of the wastewater for aeration and from the surface of the wastewater for ventilation to eliminate foam. The stirring structure 3 stirs and diffuses, and the bubbles drive the grease in the wastewater to float up, and the oxygen in the air accelerates the decomposition of substances in the wastewater and accelerates the aeration treatment;

[0059] S2, the stirring structure 3 is driven while driving the oil absorption device 4 to absorb the grease floating on the surface of the wastewater, and the adsorbed grease is squeezed out, and a defoaming agent is added to the wastewater to reduce the foam on the surface of the wastewater, thereby completing the grease separation treatment in the wastewater.
