DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1: Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, an environmentally friendly drainage device for construction includes a cylinder 100, a first filter plate 101, four support legs 104, a slag pushing mechanism 110, a stirring mechanism 120 and a filtering mechanism 200.

[0040] The top of the cylinder 100 is open, and a discharge pipe is provided at the bottom of the cylinder 100; the cylinder 100 is the main part of the entire device, and is used to contain the liquid to be treated. The top opening facilitates the entry of the liquid, and the bottom discharge pipe is used to discharge the treated sediment.

[0041] The first filter plate 101 is installed at the opening of the cylinder 100 , and is used to filter the liquid entering the cylinder 100 ; the four support legs 104 are all installed on the side of the cylinder 100 .

[0042] The slag pushing mechanism 110 is used to push away the debris on the top surface of the first filter plate 101; the stirring mechanism 120 is installed in the cylinder 100, and the stirring mechanism 120 is used to stir the liquid in the cylinder 100 to improve the processing efficiency and improve the processing effect.

[0043] The filter mechanism 200 is installed on the cylinder 100. The filter mechanism 200 is used to discharge the liquid in the cylinder 100 and filter the discharged liquid multiple times to remove fine impurities to meet the discharge standard.

[0044] Specifically, by adding flocculants into the cylinder 100, the water to be treated is then transported to the first filter plate 101, which will filter the water to remove large particles and debris in the water, and the water will pass through the first filter plate 101 and enter the cylinder 100. The water entering the cylinder 100 will come into contact with the flocculants, so that the flocculants will flocculate the small particles and debris in the water.

[0045] Then, by starting the residue pushing mechanism 110 , the large particles and debris on the first filter plate 101 are pushed to both sides of the first filter plate 101 , so that the first filter plate 101 can filter water.

[0046] When the slag pushing mechanism 110 is in operation, the stirring mechanism 120 is also driven to operate, so that the flocculant is quickly mixed with water, thereby improving the flocculation efficiency.

[0047] After a period of time, the filter mechanism 200 is opened to discharge the water in the cylinder 100. The filter mechanism 200 can block the discharge of flocculants, and the filter mechanism 200 will also filter the water multiple times to improve the water treatment effect.

[0048] like Figure 3 and Figure 4 As shown, the slag pushing mechanism 110 includes a guide plate 111, two baffles 113, a second blocking frame 114, a scraper 116 and a driving assembly.

[0049] The guide plate 111 is installed on the cylinder 100, the middle of the guide plate 111 is a plane, the two sides of the guide plate 111 are inclined, and the middle part of the guide plate 111 is provided with a through groove 112 matching the first filter plate 101; the two baffles 113 are both installed on the guide plate 111; the second blocking frame 114 is installed on the two baffles 113; the scraper 116 is slidably connected to the two baffles 113, and the scraper 116 is in contact with the top surface of the first filter plate 101; the driving assembly is used to drive the scraper 116 to move reciprocatingly horizontally.

[0050] Specifically, by starting the driving assembly, the scraper 116 is driven to move reciprocatingly horizontally. The moving scraper 116 will push the debris on the top surface of the first filter plate 101 to the sides of the guide plate 111, and then the debris will roll down along the slopes on both sides of the guide plate 111, thereby achieving the purpose of automatically cleaning the first filter plate 101.

[0051] like Figure 1 and Figure 2 As shown, the environmentally friendly drainage device for construction also includes a conveying mechanism 140, which includes a mounting frame 141, a conveying pipe 142 and a conveying bucket 143. The mounting frame 141 is installed on the baffle 113, the conveying pipe 142 is fixedly connected to the mounting frame 141, the conveying bucket 143 is located directly above the first filter plate 101, and the conveying bucket 143 is fixedly connected to one end of the conveying bucket 143.

[0052] Specifically, when in use, by connecting the conveying bucket 143 to the conveying pipe of an external material pump and starting the material pump, the water to be treated is conveyed into the conveying pipe 142 , and then the water is discharged onto the first filter plate 101 through the conveying bucket 143 .

[0053] like Figure 3-Figure 8 As shown, the driving assembly includes a reciprocating screw 115 , a screw nut 1151 , a second bevel gear 1152 , a vertical rod 117 , a first pulley 1171 , a first bevel gear 118 and a motor 119 .

[0054] The reciprocating screw 115 is rotatably mounted on the second blocking frame 114; the screw nut 1151 is sleeved on the reciprocating screw 115, and the screw nut 1151 penetrates the scraper 116 and is fixedly connected to the scraper 116; the second bevel gear 1152 is installed on the reciprocating screw 115; the vertical rod 117 penetrates the guide plate 111 and is rotatably connected to the guide plate 111; the first pulley 1171 is fixedly sleeved on the vertical rod 117; the first bevel gear 118 is fixedly sleeved on the vertical rod 117, and the first bevel gear 118 is meshedly connected with the second bevel gear 1152; the motor 119 is installed on the side of the cylinder 100, and the power output shaft of the motor 119 is fixedly connected to the vertical rod 117.

[0055] Specifically, by starting the motor 119, the power output shaft of the motor 119 drives the vertical rod 117 to rotate, which in turn drives the first bevel gear 118 to rotate, and then engages to drive the second bevel gear 1152 to rotate, and then drives the reciprocating screw 115 to rotate, so that the screw nut 1151 moves reciprocatingly horizontally along the screw, and then drives the scraper 116 to move reciprocatingly horizontally.

[0056] like Figure 5-Figure 8 As shown, the stirring mechanism 120 includes a shaft 121 , two first stirring rods 122 , two second stirring rods 124 , a rotating rod 125 , a plurality of third stirring rods 126 , a gear 1251 , a gear ring 127 , a second pulley 128 and a transmission belt 129 .

[0057] The shaft 121 is rotatably mounted on the bottom surface of the first filter plate 101; the two first stirring rods 122 are both mounted on the shaft 121; the two second stirring rods 124 are both mounted on the shaft 121; the rotating rod 125 is rotatably mounted on the two second stirring rods 124; a plurality of third stirring rods 126 are all mounted on the rotating rod 125; the gear 1251 is mounted on the upper end of the rotating rod 125; the gear ring 127 is mounted on the inner wall of the cylinder 100, and the gear ring 127 is meshed and connected with the gear 1251; the second pulley 128 is fixedly sleeved on the shaft 121; the transmission belt 129 is sleeved on the second pulley 128 and the first pulley 1171.

[0058] Specifically, when the vertical rod 117 rotates, the shaft 121 is driven to rotate through the first pulley 1171, the transmission belt 129 and the second pulley 128, and then the first stirring rod 122 and the second stirring rod 124 are driven to rotate, thereby stirring the liquid in the cylinder 100 and improving the mixing efficiency of water and flocculant.

[0059] When the second stirring rod 124 rotates, it will drive the rotating rod 125 and the gear 1251 to rotate. The gear 1251 will rotate under the influence of the gear ring 127, thereby driving the rotating rod 125 to rotate, and then driving the third stirring rod 126 to rotate, thereby further improving the stirring effect and accelerating the liquid processing process.

[0060] like Figure 1 and Figure 7 As shown, the environmentally friendly drainage device for construction also includes a dosing pipe 102 , a sealing cover 103 and a first blocking frame 105 .

[0061] The dosing tube 102 is installed on the side of the cylinder 100; the sealing cover 103 is threadedly connected to the discharge pipe at the bottom of the cylinder 100; the first blocking frame 105 is installed on the inner wall of the cylinder 100, and the shaft 121 passes through the first blocking frame 105 and is rotatably connected to the first blocking frame 105.

[0062] Specifically, by providing the dosing tube 102, it is convenient to add flocculants into the cylinder 100. When the floccules in the cylinder 100 need to be discharged, the sealing cover 103 can be separated from the discharge tube, and the floccules can be discharged through the discharge tube. By providing the blocking frame, it is possible to prevent debris from falling on the transmission belt 129.

[0063] like Figure 1 , Fig. 9 and Fig.10 As shown, the filtering mechanism 200 includes a drainage bucket 201 , a second filtering plate 202 , a valve 203 and four sets of filtering components 210 .

[0064] The drain bucket 201 is installed on the side of the cylinder 100, and the drain bucket 201 is connected to the cylinder 100; the second filter plate 202 is installed in the drain bucket 201; the valve 203 is installed on the drain bucket 201; the four groups of filter components 210 are detachably connected, and the filter components 210 and the drain bucket 201 are detachably connected.

[0065] By providing the second filter plate 202, it is possible to prevent the flocculants in the cylinder 100 from entering the drain bucket 201. A scraper 123 is installed between the two first stirring rods 122, and the scraper 123 is in contact with the second filter plate 202. When the first stirring rod 122 rotates, the scraper 123 is driven to move, and then the scraper 123 scrapes off the debris attached to the second filter plate 202, so that the second filter plate 202 maintains a good filtering effect.

[0066] Specifically, by opening the valve 203, the water in the cylinder 100 flows out through the drainage bucket 201, and then is filtered in turn by the four groups of filter components 210 to ensure that the discharged water is clear and meets environmental protection requirements.

[0067] like Fig. 9 and Fig.10 As shown, the filter assembly 210 includes a fixed cylinder 211, a sieve plate 214, an insert cylinder 215 and a mounting hole 216. The two sides of the fixed cylinder 211 are respectively provided with a mounting groove 212 and a mounting ring 213, and the mounting groove 212 is threadedly matched with the mounting ring 213 and the drain bucket 201; the sieve plate 214 is installed in the fixed cylinder 211; the insert cylinder 215 is installed on one side of the sieve plate 214; and the mounting hole 216 is opened through the insert cylinder 215 and the fixed cylinder 211.

[0068] Specifically, by providing the mounting groove 212 and the mounting ring 213 , it is convenient to disassemble and install the plurality of fixing cylinders 211 , thereby facilitating the cleaning of the sieve plate 214 .

[0069] like Fig. 9 and Fig.10 As shown, the mesh sizes of the sieve plates 214 in the four filter assemblies 210 are all different.

[0070] Specifically, the larger the size of the mesh holes of the sieve plate 214, the closer the fixed cylinder 211 should be installed to the drain bucket 201 during installation; conversely, the smaller the size of the mesh holes of the sieve plate 214, the farther the fixed cylinder 211 should be installed from the cylinder body 100 during installation. During drainage, the water discharged from the drain bucket 201 will pass through the four sieve plates 214 in sequence, and the mesh holes of the four sieve plates 214 will become smaller and smaller, which can achieve the effect of multiple filtration.

[0071] Working principle: Before use, two containers for holding debris are placed on both sides of the guide plate 111 respectively; and flocculant is added into the cylinder 100 through the dosing pipe 102.

[0072] When in use, the conveying bucket 143 is connected to the conveying pipe of an external material pump, and the material pump is started to convey the required treated water into the conveying pipe 142 , and then the water is discharged onto the first filter plate 101 through the conveying bucket 143 .

[0073] The first filter plate 101 will filter the water, filter out large particles and debris in the water, and the water will pass through the first filter plate 101 and enter the cylinder 100. The water entering the cylinder 100 will contact the flocculant, so that the flocculant flocculates the small particles of debris in the water.

[0074] Then, by starting the motor 119, the power output shaft of the motor 119 drives the vertical rod 117 to rotate, and then drives the first bevel gear 118 to rotate, and then meshes and drives the second bevel gear 1152 to rotate, and then drives the reciprocating screw 115 to rotate, so that the screw nut 1151 moves back and forth horizontally along the screw, and then drives the scraper 116 to move back and forth horizontally. The moving scraper 116 will push the large particles and debris on the first filter plate 101 to both sides of the first filter plate 101, so that the large particles and debris fall into the container for the debris.

[0075] When the vertical rod 117 rotates, the shaft 121 is driven to rotate through the first pulley 1171, the transmission belt 129 and the second pulley 128, and then the first stirring rod 122 and the second stirring rod 124 are driven to rotate, thereby stirring the liquid in the cylinder 100 and improving the mixing efficiency of water and flocculant.

[0076] When the second stirring rod 124 rotates, it will drive the rotating rod 125 and the gear 1251 to rotate. The gear 1251 will rotate under the influence of the gear ring 127, thereby driving the rotating rod 125 to rotate, and then driving the third stirring rod 126 to rotate, thereby further improving the stirring effect and accelerating the liquid processing process.

[0077] After a period of time, by opening the valve 203, the water in the cylinder 100 flows out through the drainage bucket 201. The water discharged from the drainage bucket 201 will pass through the four sieve plates 214 in sequence, and the sieve holes of the four sieve plates 214 will become smaller and smaller, which can achieve the effect of multiple filtration and improve the water treatment effect.

[0078] When the device is not performing water treatment, the sealing cover 103 is separated from the discharge pipe, so that the flocculants in the cylinder 100 are discharged through the discharge pipe.

[0079] Example 2: Figure 1 , Fig.11 and Fig.12 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0080] The environmentally friendly drainage device for construction also includes four stabilizing mechanisms 130 , and the stabilizing mechanisms 130 include a rotating shaft 131 , a square block 132 and a bolt 133 .

[0081] The rotating shaft 131 is rotatably installed on the side of the supporting leg 104; the square block 132 is rotatably connected to the rotating shaft 131, the bottom surface of the square block 132 and the bottom surface of the supporting leg 104 are on the same horizontal line, and the square block 132 is plugged into the insert tube 215; the bolt 133 is installed through the square block 132, and the bolt 133 is plugged into the mounting hole 216.

[0082] Working principle: By providing four rotating shafts 131 and square blocks 132, the contact area between the device and the ground can be increased, thereby improving the stability of the device when in use.

[0083] Since the four fixing cylinders 211 are threadedly connected, when the device needs to be moved, the four fixing cylinders 211 are rotated in sequence to separate the four fixing cylinders 211 from each other; then the four bolts 133 are separated from the four square blocks 132 respectively; then, the disassembled fixing cylinder 211 is placed near the square block 132, and the square block 132 is inserted into the insertion cylinder 215, and the above operation is repeated to insert the remaining three square blocks 132 into the other three insertion cylinders 215 respectively, so that the four fixing cylinders 211 are in contact with the ground, and the four supporting legs 104 are separated from the ground.

[0084] Finally, the bolts 133 are used to penetrate the mounting holes 216 , and the square block 132 is connected to the insert tube 215 by the bolts 133 , so that the square block 132 cannot be separated from the insert tube 215 by itself.

[0085] By using the four fixed cylinders 211 as temporary moving wheels, the entire device can be easily pushed, thereby improving the flexibility of the device.

[0086] Example 3: Figure 1-Figure 10As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0087] A method for using an environmentally friendly drainage device for construction, comprising the following steps:

[0088] Step 1: Add flocculant into the cylinder 100 through the dosing pipe 102; transport the water to be treated into the delivery pipe 142 through the material pump, and then discharge it to the first filter plate 101 through the delivery bucket 143. The first filter plate 101 performs preliminary filtration on the liquid entering the cylinder 100 to remove larger particles and impurities;

[0089] Step 2: Start the slag pushing mechanism 110, and push the debris on the top surface of the first filter plate 101 to both sides of the guide plate 111 by reciprocating horizontal movement of the scraper 116;

[0090] Step 3: When the slag pushing mechanism 110 is in operation, the transmission belt 129 and the second pulley 128 drive the shaft 121 to rotate, thereby driving the first stirring rod 122 and the second stirring rod 124 to rotate, stirring the liquid in the cylinder 100 to improve the mixing efficiency of water and flocculant;

[0091] Step 4: The stirred liquid is left to stand in the cylinder 100 for a period of time to allow the flocculant to fully function and form a precipitate;

[0092] Step 5: Open the valve 203 of the filter mechanism 200 to allow the water in the cylinder 100 to flow out through the drain bucket 201 and then be filtered in sequence through the four filter components 210.
