Description

Technical Field

[0001] This utility model relates to the field of wastewater recycling technology, specifically a sludge dewatering wastewater recycling device. Background Technology

[0002] Wastewater generated from sludge dewatering is commonly referred to as filtrate or dewatering liquid. It has a high concentration of pollutants. Recycling this wastewater can not only save water resources and reduce operating costs, but also reduce pollutant emissions. To recycle filtrate, coagulants are usually added to a coagulation tank to mix with the wastewater. Then, flocculants are added to a flocculation tank to destabilize fine colloidal particles and some dissolved organic matter, causing them to coagulate into large flocs. The flocs are then separated from the water by sedimentation or flotation.

[0003] In existing wastewater treatment processes, after adding coagulants and flocculants, the wastewater is stirred in coagulation tanks and flocculation tanks respectively by agitators to accelerate the mixing of the agents and wastewater. However, as the wastewater continues to flow in, the flow of the wastewater entering later is easily affected by the stirring action. Before it can fully contact the agents, it flows to the other side of the tank and is discharged, which can easily lead to insufficient treatment of some wastewater, reduced flocculation effect, and affect the final effluent quality. Utility Model Content

[0004] The purpose of this invention is to provide a sludge dewatering wastewater recovery device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A sludge dewatering wastewater recovery device includes: A coagulation assembly, comprising a coagulation chamber, wherein a spiral blade is fixedly installed inside the coagulation chamber, and multiple shearing rods are fixedly penetrated at equal angles on the surface of the spiral blade; A flocculation component is disposed on one side of a coagulation component. The flocculation component includes a flocculation chamber, a rotating shaft is rotatably connected inside the flocculation chamber, and a spiral filter screen is fixedly installed on the outer surface of the rotating shaft. The dosing unit is located between the coagulation chamber and the flocculation chamber.

[0006] Furthermore, a second water outlet pipe is fixedly embedded at the upper end of the outer surface of the flocculation chamber, and a discharge port is fixedly installed at the lower end of the flocculation chamber, with a sewage pump fixedly connected to one end of the discharge port.

[0007] Furthermore, a motor capable of driving the rotating shaft is fixedly installed at the upper end of the flocculation chamber.

[0008] Furthermore, a No. 1 water injection pipe is fixedly installed at the upper end of the coagulation chamber, and a No. 1 water outlet pipe is fixedly installed at the lower end of the coagulation chamber, with a solenoid valve fixedly installed at one end of the No. 1 water outlet pipe.

[0009] Preferably, a second water injection pipe is fixedly installed at the lower end of the outer surface of the flocculation chamber, and one end of the second water injection pipe is fixedly connected to a solenoid valve.

[0010] Furthermore, the dosing assembly includes: Both chemical solution tanks are fixedly installed between the coagulation chamber and the flocculation chamber; Two water pumps are fixedly connected to two medicine tanks, respectively; The liquid inlet is located at the upper part of the outer surface of the medicine tank.

[0011] Preferably, water distribution pipes are fixedly installed at the upper end of the coagulation chamber and the lower end of the flocculation chamber, and the two water distribution pipes are fixedly installed through the coagulation chamber and the flocculation chamber at corresponding positions. The two water pumps are fixedly connected to the two water distribution pipes respectively, and water distribution holes are opened at equal intervals on the outer surface of the water distribution pipes.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The water pump pumps the liquid medicine inside the tank into the distribution pipe, and then injects it into the wastewater through multiple distribution holes. By injecting at multiple points, the contact between the liquid medicine and the wastewater is increased, while the subsequent mixing time is reduced and the mixing rate is accelerated.

[0013] 2. Wastewater and coagulant are both injected from the top of the coagulation chamber and then move down along the spiral blades. During the downward movement, the two are fully mixed. At the same time, when the wastewater flows through the shearing rod, the shearing rod shears the wastewater, improving the mixing efficiency of wastewater and coagulant.

[0014] 3. The motor operates, driving the rotating shaft and spiral filter screen to rotate, which fully mixes the wastewater and flocculant. At the same time, the flocculated material generated at different heights can move downwards with the rotation of the spiral filter screen. The remaining wastewater passes through the spiral filter screen and is discharged directly from the No. 2 outlet pipe above. The flocculated material that moves to the bottom of the flocculation chamber is discharged by the sewage pump. This facilitates the active filtration of flocculated material in the flocculation chamber, speeds up the wastewater treatment process, and reduces the footprint of the wastewater recovery equipment.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 In this embodiment of the present invention, a sludge dewatering wastewater recovery device includes a coagulation component 1, which includes a coagulation chamber 101. A spiral blade 103 is fixedly installed inside the coagulation chamber 101, and multiple shearing rods 104 are fixedly inserted through the surface of the spiral blade 103 at equal angles. A flocculation component 2 is disposed on one side of the coagulation component 1. The flocculation component 2 includes a flocculation chamber 201, and a rotating shaft 202 is rotatably connected inside the flocculation chamber 201. A spiral filter screen 203 is fixedly installed on the outer surface of the rotating shaft 202. A dosing component 3 is disposed between the coagulation chamber 101 and the flocculation chamber 201, and the dosing component 3 injects coagulant and flocculant into the coagulation chamber 101 and the flocculation chamber 201 respectively.

[0019] Specifically, wastewater and coagulant are injected from the top of coagulation chamber 101 and then spiral down along spiral blades 103. During the downward movement, the two are fully mixed. At the same time, when the wastewater flows through shear rod 104, shear rod 104 shears the wastewater, improving the mixing efficiency of wastewater and coagulant. Then, it is discharged into the flocculation chamber 201. After mixing with flocculant, it flows upward into the flocculation chamber 201, increasing the flow path of wastewater. Under the rotation of spiral filter screen 203, the flocculated material moves downward.

[0020] Example 1 like Figure 1-3As shown, in this embodiment, a No. 1 water injection pipe 105 is fixedly installed at the upper end of the coagulation chamber 101, and a No. 1 water outlet pipe 102 is fixedly installed at the lower end of the coagulation chamber 101. A solenoid valve 106 is fixedly installed at one end of the No. 1 water outlet pipe 102, and the solenoid valve 106 controls the opening and closing between the coagulation chamber 101 and the flocculation chamber 201. A No. 2 water injection pipe 207 is fixedly installed at the lower end of the outer surface of the flocculation chamber 201, and one end of the No. 2 water injection pipe 207 is fixedly connected to the solenoid valve 106.

[0021] In this embodiment, wastewater is injected into the coagulation chamber 101 through the first water injection pipe 105, mixes with the coagulant and moves downward, and then is discharged from the first water outlet pipe 102. It is then injected into the flocculation chamber 201 through the second water injection pipe 207, mixes with the flocculant and flows upward.

[0022] like Figure 2 and Figure 3 As shown, in this embodiment, a second water outlet pipe 206 is fixedly embedded at the upper end of the outer surface of the flocculation chamber 201, a discharge port 205 is fixedly installed at the lower end of the flocculation chamber 201, and a sewage pump 208 is fixedly connected to one end of the discharge port 205; a motor 204 capable of driving the rotating shaft 202 to rotate is fixedly installed at the upper end of the flocculation chamber 201.

[0023] In practice, the motor 204 operates, driving the rotating shaft 202 and the spiral filter screen 203 to rotate, so that the wastewater and flocculant are fully mixed. At the same time, the flocculated material generated at different heights can move downwards with the rotation of the spiral filter screen 203. The remaining wastewater passes through the spiral filter screen 203 and is directly discharged from the No. 2 outlet pipe 206 above. The flocculated material that moves to the bottom of the flocculation chamber 201 is discharged under the action of the sewage pump 208, which facilitates the active filtration of flocculated material in the flocculation chamber 201, speeds up the wastewater treatment speed, and reduces the footprint of the wastewater recovery equipment.

[0024] Example 2 Based on Example 1, in order to solve the problem of long mixing time when the drug solution is injected into the wastewater from one place.

[0025] like Figure 1 and Figure 5 As shown, in this embodiment, the dosing assembly 3 includes: two liquid tanks 301 fixedly installed between the coagulation chamber 101 and the flocculation chamber 201; two water pumps 302 fixedly connected to the two liquid tanks 301 respectively; and an inlet 305 located at the upper end of the outer surface of the liquid tank 301, through which liquid is injected into the liquid tank 301; a water distribution pipe 303 is fixedly installed at the upper end of the coagulation chamber 101 and the lower end of the flocculation chamber 201, and the two water distribution pipes 303 are fixedly connected through the coagulation chamber 101 and the flocculation chamber 201 at corresponding positions; the two water pumps 302 are fixedly connected to the two water distribution pipes 303 respectively; and water distribution holes 304 are equidistantly opened on the outer surface of the water distribution pipes 303.

[0026] In practice, the water pump 302 operates, pumping the liquid medicine inside the liquid medicine tank 301 into the water distribution pipe 303, and then injecting it into the wastewater through multiple water distribution holes 304. By injecting at multiple points, the contact between the liquid medicine and the wastewater is increased, while the subsequent mixing time is reduced and the mixing rate is accelerated.
