When in use, the stirring component can stir the liquid in the flocculation tank to accelerate the reaction between the liquid and the flocculation reagent.

When the transmission rod rotates, it can drive the stirring rod and the baffle plate on it to rotate. The baffle plate can stir the water flow to accelerate the water flow velocity. However, the other end of the stirring rod is connected to the serpentine chute through a slider. Therefore, when the stirring rod rotates, it will move along with the serpentine chute. Since the stirring rod is composed of two sub-rods, and the two sub-rods are connected by a universal joint, and the total length of the two sub-rods is greater than the radius of the flocculation tank, the stirring rod will rotate in a bent shape in the flocculation tank, and one end position of the stirring rod is limited on the transmission rod. Therefore, when the stirring rod moves along with the serpentine chute, it will fluctuate repeatedly, so as to stir the liquid in the flocculation tank more fully. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment: As Figures 1-9 shown, the present invention provides an industrial wastewater treatment equipment with multiple separation functions, including a main body 1 of the wastewater treatment equipment and a controller 9. The main body 1 of the wastewater treatment equipment includes a separation component 2 and a flocculation component 3. A slag discharge pool 4 is installed at the bottom of the separation component 2. The separation component 2 cooperates with the flocculation component 3 and the slag discharge pool 4 respectively, and the flocculation component 3 cooperates with the slag discharge pool 4. The separation component 2 can separate the oil and sand in the wastewater, the flocculation component 3 can flocculate the remaining particles in the wastewater, and the slag discharge pool 4 can collect the sand and gravel. When the device is in use, first, industrial wastewater needs to be supplied to the separation component 2. The separation component 2 first separates the wastewater and mortar in the industrial wastewater. Then, the separated mortar can be discharged into the slag discharge pool 4, and the separated liquid will be supplied to the flocculation component 3. However, before the liquid enters the flocculation component 3, it will pass through the evaporation component 7. The evaporation component 7 can heat the passing liquid at a high temperature to remove some harmful substances in the liquid. At the same time, after heating the liquid at a high temperature, a certain amount of water vapor will be generated, and the water vapor can only be discharged when passing through the evaporation component 7. Thus, the evaporation component 7 can collect the water vapor, and the collected water vapor can be directly put into the recovery tank 11. Then, the liquid in the recovery tank 11 can be processed again according to needs. Most of the liquid will enter the flocculation component 3. The flocculation component 3 can perform secondary treatment on the filtered liquid. Specifically, in the working process, an appropriate amount of flocculant needs to be added to the flocculation tank 31 according to the total amount of the liquid, and then the stirring component 8 is started to accelerate the reaction between the flocculant and the liquid. After the reagent reaction, the liquid will have flocculent impurities and will deposit in the flocculation area 32, and the relatively clean liquid will be discharged into the recovery tank 11. After discharging the clean liquid, a small amount of the liquid will carry the flocculent impurities in it into the slag discharge pool 4 to recover the particulate matter in it. Therefore, when the device is in use, it can recover the recyclables in the industrial wastewater and disinfect some harmful substances.

[0020] As Figures 1-3 shown, in this embodiment, specifically, an installation frame 41 and a conveyor belt 42 are installed above the slag discharge pool 4. A heating component 5 is installed between the conveyor belts 42. A separation component 2 is installed between the installation frames 41. A bumping component 6 is installed inside the slag discharge pool 4. The bumping component 6 includes a bumping platform 63 and multiple groups of bumping motors 61. The multiple groups of bumping motors 61 are equidistantly installed outside the slag discharge pool 4. Multiple groups of S-shaped transmission plates 62 are installed inside the slag discharge pool 4. One end of the multiple groups of S-shaped transmission plates 62 is connected to the bumping motor 61, and the other end of the S-shaped transmission plate 62 is connected to the bumping platform 63. Filter holes are provided on the bumping platform 63. The bumping component 6 cooperates with the conveyor belt 42; When the slag discharge pool 4 of the device is in use, it can recover the sand and other particulate matter inside it. Then, according to the differences of the particulate matter, corresponding utilization can be carried out. Specifically, when in use, the separation component 2 can discharge the mortar into the slag discharge pool 4. Then, the bumping component 6 stirs inside the slag discharge pool 4, and each stirring will lift the particles in the pool. Some particles and liquid will be thrown onto the conveyor belt 42 under the inertial swing; Its working principle is as follows: The external bump motor 61 drives the S-shaped drive plate 62 to rotate. Since there are multiple groups of S-shaped drive plates 62, the movement trajectory of the bump platform 63 is limited. Each time the bump platform 63 moves to the highest position, it will move under the drive of the S-shaped drive plate 62. Then, the sand and gravel on the bump platform 63 for the liquid will be thrown onto the conveyor belt 42 under the drive of inertia. After that, the heating component 5 will heat the sand and gravel particles on the conveyor belt 42 so that they can be discharged in a dry state. Due to the structure of the conveyor belt 42, most of the liquid will return to the slag discharge pool 4 along the arc of the conveyor belt 42, and the particulate matter will be intercepted by the irregular fluff on the conveyor belt 42, thus reducing the burden on the heating component 5.

[0021] As Figure 2 shown, in this embodiment, specifically, the heating component 5 includes multiple groups of heating wires 51. The heating wires 51 are equidistantly installed between the conveyor belts 42, and the heating wires 51 can dry the sand and gravel on the conveyor belt 42; When the heating component 5 of this device is in use, it can heat and dry the sand and gravel on the conveyor belt 42, so that it is convenient to place and store when recovering particulate matters such as sand and mud. Specifically, when there is sand and mud or particulate matter on the conveyor belt 42, the controller 9 will energize the heating wires 51 to generate heat, thereby heating the sand and gravel particles on the conveyor belt 42, facilitating the subsequent recovery of particulate matters such as sand and gravel.

[0022] As Figures 1-2 and Figure 4 shown, in this embodiment, specifically, the separation component 2 includes multiple groups of cyclones 21. The multiple groups of cyclones 21 are equidistantly installed between the mounting frames 41. A sand blasting port 212 is provided at the bottom of the cyclone 21, and a water inlet 211 and an overflow port 213 are provided above the cyclone 21. The overflow port 213 cooperates with the flocculation component 3, and a transmission pipe 22 is connected between the overflow port 213 and the flocculation component 3. An evaporation component 7 is provided on the transmission pipe 22, and the evaporation component 7 can evaporate and disinfect the separated liquid; When the separation component 2 of this device is in use, it can separate the particulate matter and liquid in industrial wastewater. Specifically, when in use, first, the pipeline for transporting wastewater needs to be connected to the water inlet 211 of the cyclone 21. When the industrial wastewater enters the cyclone 21, when the two-phase mixed liquid to be separated enters the cyclone 21 tangentially from the periphery at a certain pressure, a strong three-dimensional elliptical strong rotational shear turbulent motion is generated. Due to the particle size difference between the coarse particles and the fine particles, the centrifugal force, centripetal buoyancy, fluid drag force, etc. acting on them are different. Under the action of centrifugal sedimentation, most of the coarse particles are discharged through the sand blasting port 212 at the bottom of the cyclone 21, and most of the fine particles are discharged through the overflow pipe, thus achieving the purpose of separation and grading.

[0023] AsFigure 1 , Figure 6 and Figure 7 As shown in Figure 6 and Figure 7 , in this embodiment, specifically, the evaporation assembly 7 includes an evaporation tank 71. The evaporation tank 71 is installed above the transfer pipe 22. An exhaust hole 221 is provided in the part of the transfer pipe 22 located inside the evaporation tank 71. An induction coil 72 is installed outside the transfer pipe 22. The induction coil 72 can heat the transfer pipe 22. A condensate film 711 and a water collection bin 712 are arranged inside the evaporation tank 71. A plurality of guide rods 713 are installed on the condensate film 711 and the water collection bin 712. The guide rods 713 are inclined and installed between the condensate film 711 and the water collection bin 712. The guide rods 713 incline downward from one end of the condensate film 711 to above the water collection bin 712; When the evaporation assembly 7 of the device is in use, it can perform heat treatment on the separated liquid, heating and disinfecting the separated liquid. Specifically, when the industrial wastewater after passing through the separation assembly 2 is discharged from the transfer pipe 22 to the flocculation assembly 3, it will pass through the evaporation assembly 7. Through the induction coil 72 of the evaporation assembly 7, the transfer pipe 22 can be heated, and the liquid passing through the transfer pipe 22 will be indirectly heated. After the liquid is heated at a high temperature, a certain amount of steam will be generated. Then, when passing through the evaporation tank 71, the steam will be discharged through the exhaust hole 221. After that, the steam will be adsorbed on the condensate film 711. Because the condensate film 711 is limited by the guide rods 713, the steam on the condensate film 711 will form water droplets and enter the water collection bin 712 through the guide rods 713. Then, the water collection bin 712 will discharge the collected liquid into the recovery tank 11.

[0024] As Figure 5 shown in Figure 5 , in this embodiment, specifically, the flocculation assembly 3 includes a flocculation tank 31. A stirring motor is installed above the flocculation tank 31. A stirring assembly 8 is installed inside the flocculation tank 31. The output end of the stirring motor is connected to the stirring assembly 8. A flocculation area 32 is provided at the bottom of the flocculation tank 31. The flocculation area 32 is connected to the slag discharge tank 4. A recovery tank 11 is provided on the side of the flocculation tank 31. The recovery tank 11 is respectively connected to the water collection bin 712 and the flocculation tank 31; When the flocculation assembly 3 of the device is in use, it can perform flocculation treatment on the separated liquid. Because there are still a small number of particles in the liquid separated by the separation assembly 2, only the particles are relatively small. The flocculation assembly 3 can flocculate the fine particles among them. Specifically, when in use, the staff needs to add a certain amount of flocculation reagent according to the total amount of the liquid in the flocculation tank 31, and then start the stirring motor. The stirring motor can drive the stirring assembly 8, thereby accelerating the reaction between the liquid and the reagent. The flocculated particles will slowly settle into the flocculation area 32, and the flocculated particles in the flocculation area 32 will be discharged into the slag discharge tank 4 for recycling of the particulate matter.

[0025] AsFigure 5 and Figure 9 As shown in Figure 9 , in this embodiment, specifically, a plurality of serpentine chutes 311 are provided on the inner wall of the flocculation tank 31. The stirring assembly 8 includes a transmission rod 81. A plurality of stirring rods 82 and a plurality of baffles 84 are provided on the transmission rod 81. The stirring rods 82 are connected to the transmission rod 81 through universal joints. A slider 83 is installed at the other end of the stirring rod 82. The slider 83 cooperates with the serpentine chute 311. Both ends of the stirring rod 82 are connected to the slider 83 and the transmission rod 81 through bearings respectively. The stirring rod 82 includes two sub-rods 821. The two sub-rods 821 are connected through a universal joint. The total length of the two sub-rods 821 is greater than the radius of the flocculation tank 31; When the stirring assembly 8 of this device is in use, it can stir the liquid in the flocculation tank 31 to accelerate the reaction between the liquid and the flocculation reagent. Specifically, when in use, the stirring assembly 8 will work driven by a stirring motor. The stirring motor can drive the transmission rod 81 to rotate. When the transmission rod 81 rotates, it can drive the stirring rods 82 and the baffles 84 thereon to rotate. The baffles 84 can stir the water flow to accelerate the water flow velocity. However, the other end of the stirring rod 82 is connected to the serpentine chute 311 through the slider 83. Therefore, when the stirring rod 82 rotates, it will move along with the serpentine chute 311. Because the stirring rod 82 is composed of two sub-rods 821, and the two sub-rods 821 are connected through a universal joint, and the total length of the two sub-rods 821 is greater than the radius of the flocculation tank 31, the stirring rod 82 will rotate in a bent shape in the flocculation tank 31. And the position of one end of the stirring rod 82 is limited on the transmission rod 81. Therefore, when the stirring rod 82 moves along with the serpentine chute 311, it will fluctuate repeatedly, so as to stir the liquid in the flocculation tank 31 more fully.

[0026] As Figure 1 shown in Figure 1 , in this embodiment, specifically, a controller 9 is installed on the side of the main body 1 of the wastewater treatment equipment. The controller 9 is connected to the main body 1 of the wastewater treatment equipment. An operation panel 91 is provided on the controller 9. The operation panel 91 can indirectly control the main body 1 of the wastewater treatment equipment; When this device is in use, it can control the entire main body 1 of the wastewater treatment equipment through the controller 9, and the control panel on the controller 9 is convenient for workers to operate. Therefore, the staff can indirectly control the entire equipment through the control panel.

[0027] As Figures 1-9 shown, the present invention provides an industrial wastewater treatment method with multiple separation functions. The treatment method is applicable to an industrial wastewater treatment equipment with multiple separation functions according to any one of claims 1-8. The treatment method includes the following steps: S1: The separation component separates the wastewater; S2: The slag discharge pool dries and recovers the sand and gravel; S3: The evaporation component heats and disinfects the separated liquid; S4: The flocculation component performs secondary treatment on the separated liquid.

[0028] As Figures 1-9 shown, in this embodiment, specifically, S1 includes S11: The separation component separates the industrial wastewater into mortar and a small amount of impurity liquid. The mortar enters the slag discharge tank, and the liquid enters the flocculation component through the evaporation component; S2 includes S21: The slag discharge tank throws the sand and gravel onto the conveyor belt through the jolting component, and the heating component dries the sand and gravel on the conveyor belt; S3 includes S31: After the evaporation component heats the separated liquid, the generated steam will enter the water collection bin, disinfecting the liquid and recycling a small amount of liquid at the same time; S4 includes S41: After the liquid enters the flocculation tank, a certain amount of flocculant is added to separate the impurities in the liquid from the liquid; S42: The separated liquid enters the recovery tank, and the separated flocculated impurities enter the slag discharge tank.

[0029] Working principle: When the device is in use, first, the industrial wastewater needs to be supplied to the separation component 2. The separation component 2 first separates the wastewater and mortar in the industrial wastewater, and then the separated mortar can be discharged into the slag discharge tank 4. The separated liquid will be supplied to the flocculation component 3. However, before the liquid enters the flocculation component 3, it will also pass through the evaporation component 7. The evaporation component 7 can heat the passing liquid at a high temperature to remove some harmful substances in the liquid. At the same time, after heating the liquid at a high temperature, a certain amount of water vapor will be generated, and the water vapor can only be discharged when passing through the evaporation component 7. Thus, the evaporation component 7 can collect the water vapor, and the collected water vapor can be directly put into the recovery tank 11. Then, the liquid in the recovery tank 11 can be processed again according to needs. Most of the liquid will enter the flocculation component 3. The flocculation component 3 can perform secondary treatment on the filtered liquid. Specifically, the working process requires adding an appropriate amount of flocculant to the flocculation tank 31 according to the total amount of the liquid, and then starting the stirring component 8 to accelerate the reaction between the flocculant and the liquid. After the reaction of the reagent, the liquid will show flocculent impurities and deposit in the flocculation area 32, and the relatively clean liquid will be discharged into the recovery tank 11. After discharging the clean liquid, a small amount of liquid will carry the flocculent impurities therein into the slag discharge tank 4 to recover the particulate matter therein. Therefore, when the device is in use, it can recover the recyclables in the industrial wastewater and disinfect some harmful substances.

Therefore, in any respect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description.
