Description

Technical Field

[0001] This invention relates to the field of water treatment technology, and in particular to a wastewater recycling treatment device. Background Technology

[0002] Wastewater treatment projects are an important part of urban municipal construction, industrial enterprise construction, or sewage discharge compliance treatment. Wastewater treatment methods include physical treatment and chemical treatment. Chemical treatment involves adding chemical agents to the wastewater pond to purify the water. The agents added are generally flocculants, coagulants, and defoamers. During the dosing process, adding too much chemical agent will result in waste, while adding too little chemical agent will result in poor wastewater purification effect.

[0003] Therefore, in wastewater treatment, dosing devices are generally used to more precisely control the dosage of chemicals. Conventional dosing devices typically control and monitor the storage tank, the liquid level within the tank, and the outflow of chemicals, focusing only on dosage. They tend to overlook the mixing of chemicals and wastewater. Furthermore, the addition of chemicals and wastewater treatment are not synchronized. Wastewater is usually introduced into the wastewater tank before chemicals are added. This process requires determining the wastewater volume before controlling the chemical dosage, which is time-consuming and leaves room for improvement in wastewater treatment efficiency. Additionally, chemicals are generally applied to wastewater in the wastewater tank. In confined water treatment environments, it is difficult to arrange a large wastewater tank, hindering the implementation of streamlined wastewater treatment processes. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a wastewater recycling treatment device to solve the problem that conventional chemical wastewater treatment processes require introducing wastewater into a wastewater tank before adding chemicals, which necessitates determining the wastewater volume and controlling the amount of chemicals added, resulting in a time-consuming process and low wastewater treatment efficiency.

[0005] To achieve the above objectives, the basic solution of the present invention is as follows: a wastewater recycling treatment device, comprising:

[0006] Water treatment cylinder;

[0007] Several blades located inside the water treatment cylinder;

[0008] A rotating shaft is fixedly connected to several blades. The rotating shaft is coaxially rotated and sealed on the water treatment cylinder. The side walls of the blades away from the rotating shaft are all in contact with the inner wall of the water treatment cylinder. A separation treatment cavity is formed between the surface of two adjacent blades and the inner wall of the water treatment cylinder.

[0009] The inlet and outlet pipes are connected to the water treatment cylinder, and the inlet pipe can be opposite to a single partitioned treatment chamber;

[0010] A dosing control unit, which can be located opposite to a single partitioned processing chamber, includes a dosing device, a PLC controller, a speed sensor for detecting the rotational speed of the shaft, and a dosing controller for controlling the dosing frequency of the dosing device. The dosing device is electrically connected to the dosing controller, and both the dosing controller and the speed sensor are electrically connected to the PLC controller. When the rotational speed of the shaft measured by the speed sensor changes, the dosing controller controls the dosing frequency of the dosing device to change proportionally.

[0011] The technical principle of this invention is as follows: Wastewater enters the water treatment cylinder through the inlet pipe. At this time, the wastewater can impact the blades, and the impact force drives the rotating shaft to rotate. The speed sensor detects the rotation speed of the shaft, and the speed signal is transmitted to the PLC controller. The PLC controller comprehensively judges and processes the speed signal and outputs the dosing frequency. The control of the dosing frequency ensures that two dosings do not occur in the same compartment, so that the agent in a single compartment meets the standard. This allows for a more precise match between the agent dosage and the amount of wastewater to be treated, reducing the amount of residual agent in the wastewater and avoiding the waste of excess agent.

[0012] At the same time, wastewater is sequentially fed into the separate treatment chambers, which simultaneously drive several blades and the rotating shaft to rotate synchronously, allowing the wastewater to enter each separate treatment chamber and mix with the chemicals. When the wastewater and chemicals rotate to the outlet pipe, the wastewater and chemicals are discharged. In the above process, real-time chemical treatment is also achieved during the wastewater transfer, which improves the wastewater treatment efficiency and simplifies the chemical treatment steps of wastewater treatment. Compared with setting up several large wastewater treatment tanks, the entire wastewater recycling treatment equipment saves more layout space.

[0013] When different chemicals need to be added in different wastewater treatment processes, simply changing the type of chemical added to the dosing device allows for different treatment processes of the wastewater. It can also allow the wastewater recycling equipment to recycle the wastewater, thus expanding the applicable scenarios of the wastewater recycling equipment.

[0014] Furthermore, the dosing device passes through the water treatment cylinder and can be opposite a single partitioned treatment chamber, and the dosing device is located above the inlet and outlet pipes.

[0015] With the above configuration, the dosing device can more easily pump the chemicals vertically into the individual compartments, and the wastewater can more easily enter the lower part of the water treatment cylinder, so that the dosing frequency of the dosing device can quickly respond to the different rotation speeds of the shaft.

[0016] Furthermore, elastic sealing strips are fixedly installed on the three sides of the blade that are in contact with the inner wall of the water treatment cylinder, and the elastic sealing strips are in contact with the inner wall of the water treatment cylinder.

[0017] With the above settings, the elastic sealing strip can more accurately separate the treatment chambers, making the matching of chemicals and sewage volume more precise.

[0018] Furthermore, the side of the blade away from the rotating shaft is recessed in a clockwise or counterclockwise direction to form a groove, and the inner wall of the blade groove can be opposite to the end of the water inlet pipe near the water treatment cylinder.

[0019] By designing the grooves, wastewater can more accurately impact the blades, and the wastewater in the guide channels of the grooves can also more accurately impact the angle between two adjacent blades, allowing for more thorough mixing of the wastewater with the chemicals between the two adjacent blades.

[0020] Furthermore, the bottom surface of the groove is arc-shaped, and the thickness of the longitudinal section profile of the groove increases sequentially from the center of the water treatment cylinder towards the circumference.

[0021] With the above setup, the curved grooved floor can further guide the sewage, allowing the sewage and the chemicals to mix more thoroughly.

[0022] Furthermore, a liquid pressure sensor is installed on the bottom surface of each blade groove. The liquid pressure sensor is electrically connected to the PLC controller. When the sewage pressure measured by the liquid pressure sensor changes, the dosing controller controls the dosing frequency of the dosing device to change proportionally.

[0023] With the above setup, the sewage impacts the liquid pressure sensor in the groove, which transmits the pressure signal to the PLC controller. The PLC controller processes the pressure and speed signals and outputs the dosage. The dosage and frequency signals are transmitted to the dosing controller, which controls the dosing device to dosing with the corresponding frequency and dosage, so that both the dosage and frequency can be controlled in real time, thus improving the dosing accuracy.

[0024] Furthermore, the water inlet pipe includes a pump inlet pipe and a first connecting pipe. A first liquid pump is connected to one end of the pump inlet pipe, and the other end of the pump inlet pipe is coaxially and detachably sealed to one end of the first connecting pipe. The other end of the first connecting pipe is fixedly connected to the water treatment cylinder.

[0025] With the above configuration, the first liquid pump can provide power for the transfer and treatment of sewage, making it easier for the sewage to drive the blades and shaft to rotate, so as to achieve synchronization between the addition of chemicals and the transfer of sewage, thereby improving the sewage treatment efficiency.

[0026] Furthermore, the water outlet pipe includes a second connecting pipe and a pump outlet pipe. A second liquid pump is connected to one end of the pump outlet pipe, and the other end of the pump outlet pipe is coaxially and detachably sealed to one end of the second connecting pipe. The other end of the second connecting pipe is fixedly connected to the water treatment cylinder. The second connecting pipe and the first connecting pipe are symmetrically arranged along the vertical centerline of the longitudinal section of the water treatment cylinder.

[0027] With the above configuration, the second liquid pump can work in conjunction with the first liquid pump to provide power for the transfer and treatment of sewage, and the sewage is discharged from the water treatment tank, further improving the sewage treatment efficiency.

[0028] Furthermore, the outer wall of the water treatment cylinder is provided with several protrusions, which are located between the inlet pipe and the outlet pipe, and the protrusions are opposite to the dosing device.

[0029] The above design ensures that when the wastewater recycling equipment is placed on the ground, the protrusion contacts the ground, providing support for the entire wastewater recycling equipment.

[0030] Furthermore, a filter screen is detachably installed inside the water outlet pipe, covering the longitudinal section of the water outlet pipe. An opening opposite to the filter screen is provided on the upper surface of the water outlet pipe, and a cap is detachably and sealingly installed at the opening of the water outlet pipe.

[0031] With the above setup, when the wastewater and the reagent are mixed and enter the second connecting pipe and the pump outlet pipe, the impurities in the wastewater are easily flocculated under the action of the reagent. At this time, the flocculated impurities impact the filter screen, which can intercept the flocculated impurities, preventing a large number of impurities from entering the next treatment process and also protecting the second liquid pump.

Detailed Implementation

[0038] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0039] Example 1

[0040] This embodiment is basically as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment of the invention proposes a wastewater recycling treatment device, including a water treatment cylinder 10, a plurality of blades 20 located inside the water treatment cylinder 10, a rotating shaft 30 fixedly connected to the plurality of blades 20, an inlet pipe 40 and an outlet pipe 50 communicating with the water treatment cylinder 10, and a dosing control unit that can be opposite to a single partitioned treatment chamber 201. The rotating shaft 30 is coaxially and rotatably sealed on the water treatment cylinder 10. The planes where the blades 20 are located are coplanar along the radial section of the water treatment cylinder 10. The sidewalls of the blades 20 away from the rotating shaft 30 are all in contact with the inner wall of the water treatment cylinder 10. A partitioned treatment chamber 201 is formed between the surface of two adjacent blades 20 and the inner wall of the water treatment cylinder 10. Figure 2 As shown, an auxiliary motor 301 is installed on the water treatment cylinder 10, and the power output end of the auxiliary motor 301 is coaxially and fixedly connected to the rotating shaft 30.

[0041] like Figure 1 As shown, elastic sealing strips 202 are fixedly installed on the three sides of the blade 20 that are in contact with the inner wall of the water treatment cylinder 10. The elastic sealing strips 202 are in contact with the inner wall of the water treatment cylinder 10. The side of the blade 20 away from the rotating shaft 30 is recessed in a clockwise or counterclockwise direction to form a groove 203. The inner wall of the groove 203 of the blade 20 can be opposite to the end of the water inlet pipe 40 that is close to the water treatment cylinder 10. At the same time, the bottom surface of the groove 203 is arc-shaped, and the thickness of the longitudinal section profile of the groove 203 increases from the center of the water treatment cylinder 10 to the circumference.

[0042] like Figure 1 and Figure 2As shown, the inlet pipe 40 can be opposite to a single partitioned processing chamber 201, and the outlet pipe 50 can also be opposite to a single partitioned processing chamber 201. Simultaneously, the inlet pipe 40 includes a pump inlet pipe 401 and a first connecting pipe 402. A first liquid pump (not shown) is connected to the left end of the pump inlet pipe 401, and the right end of the pump inlet pipe 401 is coaxially connected to the left end of the first connecting pipe 402. Both the right end of the pump inlet pipe 401 and the left end of the first connecting pipe 402 are provided with flanges. The right end of the pump inlet pipe 401... Several mounting holes are provided circumferentially along the flange. A screw rod that can pass through the mounting holes is integrally formed on the flange at the left end of the first connecting pipe 402. A nut that abuts against the right flange of the pump inlet pipe 401 is threaded onto the screw rod. A rectangular sealing ring is installed inside the right end of the pump inlet pipe 401 and the left end of the first connecting pipe 402. The right end of the first connecting pipe 402 is integrally formed with and communicates with the middle left side of the water treatment cylinder 10, and the inner wall of the right end of the first connecting pipe 402 smoothly transitions with the inner wall of the water treatment cylinder 10.

[0043] like Figure 1 and Figure 2 As shown, the outlet pipe 50 includes a second connecting pipe 501 and a pump outlet pipe 502. A second liquid pump (not shown) is connected to the right end of the pump outlet pipe 502. The left end of the pump outlet pipe 502 is coaxially connected to the right end of the second connecting pipe 501. Both the left end of the pump outlet pipe 502 and the right end of the first connecting pipe 402 are provided with flanges. Several mounting holes are provided circumferentially on the flange at the right end of the first connecting pipe 402. A screw that can pass through the mounting holes is integrally formed on the flange at the left end of the pump outlet pipe 502. The rod is threaded with a nut that abuts against the right flange of the first connecting pipe 402. A rectangular sealing ring is installed inside the left end of the pump outlet pipe 502 and the right end of the first connecting pipe 402. The left end of the second connecting pipe 501 is integrally formed with and connected to the middle right side of the water treatment cylinder 10, and the inner wall of the left end of the second connecting pipe 501 smoothly transitions with the inner wall of the water treatment cylinder 10. At the same time, the second connecting pipe 501 and the first connecting pipe 402 are symmetrically arranged along the vertical centerline of the longitudinal section of the water treatment cylinder 10 in the main viewing direction.

[0044] like Figure 3 and Figure 4As shown, the dosing control unit includes a dosing device 60, a PLC controller, a speed sensor for detecting the rotation speed of the rotating shaft 30, a dosing controller for controlling the dosing frequency of the dosing device 60, a first controller for controlling the opening and closing of the first liquid pump, and a second controller for controlling the opening and closing of the second liquid pump. The dosing device 60 is a hydraulic proportional dosing pump. The dosing device 60 passes through the water treatment cylinder 10 and can be opposite to a single partitioned treatment chamber 201. The dosing device 60 is located above the inlet pipe 40 and the outlet pipe 50. A chemical storage tank 601 is connected above the dosing device 60 and is fixedly installed at the center of the top of the water treatment cylinder 10. At the location, the dosing device 60 and the storage tank 601 are coaxially arranged; the dosing device 60 is electrically connected to the dosing controller, and the dosing controller, speed sensor, first controller and second controller are all electrically connected to the PLC controller. When the speed of the rotating shaft 30 changes as measured by the speed sensor, the dosing controller controls the dosing frequency of the dosing device 60 to change proportionally; at the same time, a liquid pressure sensor 204 is installed on the bottom surface of the groove 203 of the blade 20. The liquid pressure sensor 204 is electrically connected to the PLC controller. When the sewage pressure measured by the liquid pressure sensor 204 changes, the dosing controller controls the dosing frequency of the dosing device 60 to change proportionally.

[0045] In addition, such as Figure 1 and Figure 2 As shown, two protrusions 101 are fixedly welded on the outer wall of the water treatment cylinder 10. Both protrusions 101 are located between the inlet pipe 40 and the outlet pipe 50, and the protrusions 101 are opposite to the dosing device 60. This makes it easy for the protrusions 101 to contact the ground when the sewage circulation treatment equipment is placed on the ground, so as to support the entire sewage circulation treatment equipment. At the same time, the distance between two adjacent blades 20 on the side away from the rotating shaft 30 is less than or equal to the first connecting pipe 402 or the vertical thickness of the first connecting pipe 402.

[0046] In this embodiment, a wastewater recycling treatment device is first installed on the ground. The pump inlet pipe 401, the first connecting pipe 402, the second connecting pipe 501, and the pump outlet pipe 502 are all inclined relative to the ground, with the second connecting pipe 501 and the pump outlet pipe 502 located below the pump inlet pipe 401 and the first connecting pipe 402. The required water treatment agent is prepared according to the properties of the wastewater to be treated and poured into the storage tank 601. Then, the PLC controller controls the first liquid pump to start via the first controller, and the second controller controls the second liquid pump to start simultaneously. The first liquid pump pumps the wastewater to be treated sequentially into the pump inlet pipe 401 and the first connecting pipe 402, and then into the partitioned treatment chamber 201 of the water treatment cylinder 10. The wastewater impacts the groove 2. On the liquid pressure sensor 204 of 03, the liquid pressure sensor 204 transmits the pressure signal to the PLC controller; at the same time, when the sewage impacts the blade 20, the impact force drives the rotating shaft 30 to rotate. The speed sensor detects the speed of the rotating shaft 30 and transmits the speed signal to the PLC controller. The PLC controller comprehensively judges and processes the pressure signal and speed signal and outputs the dosage. The dosage and frequency signals are transmitted to the dosing controller. The dosing controller controls the dosing device 60 to dosing at the corresponding frequency and dosage. The dosing device 60 pumps the corresponding dosage into a single compartment 201 according to the dosage. The control of the dosing frequency ensures that two dosings do not occur in the same compartment 201, so that the agent in the single compartment 201 meets the standard.

[0047] At this time, the wastewater to be treated is filled into the partitioned treatment chamber 201 under the negative pressure suction of the first and second liquid pumps. Simultaneously, several blades 20 and the rotating shaft 30 rotate synchronously, so that the wastewater enters each partitioned treatment chamber 201 in sequence and mixes with the agent. The rotating blades 20 can also mix the wastewater and the agent. When the wastewater and the agent rotate to the second connecting pipe 501 and the pump outlet pipe 502, the second liquid pump tightly sucks the wastewater and the agent in the right partitioned treatment chamber 201, so that the wastewater and the agent enter the next treatment process. At the same time, due to the inclined setting of the wastewater circulation treatment equipment, the wastewater and the agent in the partitioned treatment chamber 201 can also be discharged into the second connecting pipe 501 and the pump outlet pipe 502 as completely as possible, reducing the residue in the partitioned treatment chamber 201 and improving the accuracy of the ratio of the agent and the newly entering wastewater in the partitioned treatment chamber 201.

[0048] During the above process, with the rotational speed of the shaft 30 and the impact force of the sewage, it can be known that the flow rate and volume of the sewage entering the separation treatment chamber 201 will change equally. With the cooperation of the blade 20, the shaft 30, the PLC controller, and the dosing controller, the amount of chemical added and the frequency of chemical dosing can be quickly adjusted according to the sewage inflow and input, so that the dosage of chemical is more accurately matched with the amount of sewage to be treated, reducing the amount of chemical residue in the sewage and avoiding the waste of excess chemical. In the above process, real-time chemical treatment is also realized during the sewage transfer, improving the sewage treatment efficiency and simplifying the chemical treatment steps of sewage treatment. The entire sewage circulation treatment equipment saves more layout space compared to setting up several large sewage treatment tanks.

[0049] When different chemicals need to be added in different wastewater treatment processes, the wastewater can be treated in different processes simply by changing the type of chemical in the storage tank 601. It can also be used to recycle wastewater, thus expanding the applicable scenarios of the wastewater recycling equipment.

[0050] When the sewage recycling treatment equipment has been used for a long time and a lot of sludge or impurities have accumulated inside it, the nuts at the first connecting pipe 402, the pump inlet pipe 401, the second connecting pipe 501, and the pump outlet pipe 502 can be removed. The blades 20 inside the water treatment cylinder 10 can be cleaned through the first connecting pipe 402 and the second connecting pipe 501. During cleaning, the blades 20 are moved to drive the rotating shaft 30 to rotate, making the cleaning of the entire sewage recycling treatment equipment convenient.

[0051] The auxiliary motor 301 can be started when sewage begins to enter or when sewage treatment is completed and the amount of sewage entering the treatment cylinder is insufficient. When the sewage begins to enter and the impact force is insufficient, the rotating shaft 30 can rotate first, allowing the dosing device 60 to initially spray the agent normally. When sewage treatment is completed, the rotating shaft 30 continues to rotate, and the blades 20 scrape the sewage remaining in the water treatment cylinder 10 into the second connecting pipe 501 and the pump outlet pipe 502, allowing the sewage in the water treatment cylinder 10 to be emptied and kept in a relatively clean state.

[0052] Example 2

[0053] The main differences between Example 2 and Example 1 are as follows: Figure 5 As shown, the top of the water outlet pipe 50 is provided with an opening 701, and a cover 702 is detachably and sealingly installed at the opening 701 of the water outlet pipe 50. The side wall of the cover 702 and the opening 701 of the water outlet pipe 50 are both in the shape of nested bosses, and a rectangular sealing ring 703 is provided at the side wall of the cover 702 to fit with the opening 701 of the water outlet pipe 50.

[0054] like Figure 5As shown, a filter screen 704 is detachably installed inside the pump outlet pipe 502. The filter screen 704 has a cylindrical structure, with a closed mesh at the right end. A rectangular mounting ring 705 is fixedly installed on the left end of the filter screen 704. The mounting ring 705 is made of elastic rubber, and its inner wall is hollow and has a pull rope 706 embedded in it. The lower surface of the cover 702 and the inner wall of the pump outlet pipe 502 are provided with annular grooves 203 for the mounting ring 705 to be embedded in. A through hole 707 communicating with the annular groove 203 is vertically provided on the cover 702. The mounting ring 705 is provided with an outlet hole communicating with the through hole 707. The middle part of the pull rope 706 passes through the outlet hole and the through hole 707 and is integrally formed into a pull ring 708.

[0055] In addition, a handle 709 is welded to the upper surface of the cap 702.

[0056] In this embodiment, when the wastewater and the chemical agent are mixed and enter the second connecting pipe 501 and the pump outlet pipe 502, the impurities in the wastewater are easily flocculated under the action of the chemical agent. At this time, the flocculated impurities impact the filter screen 704, which can intercept the flocculated impurities, preventing a large number of impurities from entering the next treatment process and also protecting the second liquid pump.

[0057] When excessive impurities accumulate on the filter screen 704, hold the pull ring 708 and press the cover 702. Pulling the pull ring 708 tightens the pull rope 706, which in turn tightens the mounting ring 705, causing the left end of the filter screen 704 to close, thus collecting the impurities into the filter screen 704. Then, hold the handle 709 and remove the cover 702 from the pump outlet pipe 502. The cover 702 will pull the entire filter screen 704 out. Then, loosen the pull ring 708, and the mounting ring 705 will close. The pull rope 706 on the filter 5 is simultaneously loosened, and the mounting ring 705 springs back into a ring shape. Then, the impurities in the filter screen 704 are cleaned. After the impurities on the filter screen 704 are cleaned, the mounting ring 705 is tightened again, and the entire filter screen 704 is pushed back into the pump outlet pipe 502 through the opening 701. The mounting ring 705 is also locked into the annular groove 203 of the cover 702 and the pump outlet pipe 502, so that the entire filter screen 704 is installed and fixed in place, and the collection of impurities can continue.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
