Description

Technical Field

[0001] This invention relates to the field of pesticide production equipment technology, specifically to a wastewater treatment device for pesticide production. Background Technology

[0002] With the continuous development of technology, people use pesticides to control pests on crops when carrying out agricultural work. Compared with the original manual pest control, pesticides not only improve work efficiency but also greatly reduce people's labor intensity. However, the production of pesticides generates a large amount of pesticide wastewater. If pesticide wastewater is discharged directly without treatment, it will cause a lot of water pollution problems. Therefore, it is particularly important to treat pesticide wastewater with pesticide wastewater treatment equipment before discharge.

[0003] To this end, Chinese Patent Publication No. CN213326883U discloses a "Sedimentation Device for Treating Pesticide Wastewater," the main structure of which includes a sedimentation tank. A U-shaped material-distributing frame is fixedly installed at the top of the sedimentation tank. A first motor is fixedly installed in the middle of the upper surface of the sedimentation tank, and the output end of the first motor is connected to a transmission rod. The transmission rod is vertically positioned in the middle of the material-distributing frame, and material-distributing plates are horizontally fixedly installed on both sides of the bottom of the transmission rod. A second motor is fixedly installed at the bottom left side of the sedimentation tank, and the output end of the second motor is connected to a conveying rod, which is horizontally positioned at the bottom of the sedimentation tank. This sedimentation device for treating pesticide wastewater, through the coordinated use of the material-distributing frame installed in the sedimentation tank, the first motor, the transmission rod, and the material-distributing plates, allows the precipitant to be poured into the material-distributing frame inside the sedimentation tank through the inlet. The first motor drives the material-distributing plates to rotate via the transmission rod, which can evenly distribute the precipitant into the sedimentation tank, accelerating the sedimentation of pesticide wastewater and improving the effectiveness of the precipitant.

[0004] It is obvious that the above-mentioned sedimentation device for treating pesticide wastewater requires the first motor to drive the screw to rotate, so as to evenly distribute the precipitant in the sedimentation tank. Therefore, the rated power of the screw and the motor must change with the volume of the sedimentation tank. At the same time, the wastewater far from the screw area is difficult to mix fully with the precipitant. Therefore, it has the defects of low working efficiency and poor mixing effect. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a wastewater treatment device for pesticide production. This device can autonomously mix a precipitant into the pesticide wastewater as it flows into a sedimentation tank, based on the kinetic energy of the wastewater discharge. This results in high mixing efficiency and high mixing uniformity. Furthermore, the device autonomously adjusts the amount of precipitant added to the sedimentation tank according to the wastewater flow rate, providing an adaptive adjustment function and solving the aforementioned technical problems.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 and Figure 2 A wastewater treatment device for pesticide production includes a central drain pipe 1 with an internal wastewater flow chamber 2, an installation channel 3 located on the circumferential side of the central drain pipe 1, and a hollow mounting frame 4 installed inside the central drain pipe 1. During installation, the agent injection channel 55 is connected to the drain port of a storage tank containing a precipitant, and the precipitant inside the storage tank can flow into the agent injection channel 55 under its own gravity. At the same time, the two ends of the central drain pipe 1 are connected to the beginning and end pipes for discharging wastewater. It should be noted that after installation, the flow direction of the wastewater is from the driven mixing mechanism 5 to the unidirectional flow control mechanism 6, and finally flows into the sedimentation tank.

[0021] To utilize the potential energy of wastewater to generate an adaptive reagent mixing function, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 3 and Figure 4A driven mixing mechanism 5 needs to be set up. Its structure includes a first hollow cylinder 51 installed at the center of the hollow mounting frame 4 and having a hollow internal structure; a spiral blade 510 installed at the shaft of the first hollow cylinder 51 and capable of compressing and conveying the precipitant; a turbine fan blade 59 installed inside the sewage flow chamber 2 and capable of rotating under the impact of water flow; and a coupling 57 that causes the spiral blade 510 to rotate with the turbine fan blade 59. When sewage flows inside the sewage flow chamber 2, the turbine fan blade 59 will rotate under the impact of water flow. Under the linkage effect of the coupling 57, the spiral blade 510 will rotate accordingly. The precipitant located around the spiral blade 510 will tend to flow towards the inlet hole 64 under the drive of the spiral blade 510. The rotation speed of the turbine fan blade 59 will change with the change of sewage flow velocity, thereby utilizing the potential energy of sewage to generate an adaptive agent mixing function.

[0022] For details regarding the structure of the driven mixing mechanism 5, please refer to [link / reference]. Figure 3 and Figure 4 It also includes a drug compression chamber 52 located inside a first hollow cylinder 51 and open at one end. The solid end of the drug compression chamber 52 has a shaft mounting hole 54. The first hollow cylinder 51 has a drug injection channel 55 on its circumferential side near the shaft mounting hole 54, communicating with the drug compression chamber 52.

The central rotating shaft 56 has an integrally formed spiral blade 510 on its shaft located inside the drug compression chamber 52. A driven roller 58 is installed at the outer end of the central rotating shaft 56 via a coupling 57. The outer circumference of the 58 is provided with multiple turbine blades 59 integrally formed with it. The first hollow cylinder 51 is provided with a first docking plate 53 integrally formed with it at the opening end of the agent compression chamber 52. During installation, the agent injection channel 55 is connected to the drain port of a storage tank containing precipitant, and the precipitant inside the storage tank can flow into the agent injection channel 55 under its own gravity. The driven roller 58 and the first hollow cylinder 51 are provided with a conical structure at the end facing the sewage flow to facilitate sewage flow. The center of the driven roller 58 is provided with a hollow structure to reduce its overall weight. When the turbine blades 59 rotate with the sewage flow, the rotation of the spiral blades 510 causes the precipitant around them to flow toward the opening end of the agent compression chamber 52.

[0023] To achieve the one-way mixing function of the drug, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 5 and Figure 6A one-way flow control mechanism 6 needs to be set up. Its structure includes a second hollow cylinder 61 fixedly installed at the tail end of the first hollow cylinder 51 and having a hollow internal structure, a movable valve plate 66 placed inside the second hollow cylinder 61 and capable of controlling the flow state of the precipitant, and a helical spring 610 that generates an elastic damping effect on the movement of the movable valve plate 66. When the flow pressure of the precipitant is greater than the elastic pressure of the helical spring 610, the helical spring 610 will be compressed, and the movable valve plate 66 will move. At this time, the precipitant will sequentially enter the central area of ​​the sewage flow through the inlet hole 64, the movement gap of the movable valve plate 66, the liquid flow channel 67, the component movement cavity 63, and multiple drain holes 65. Finally, the precipitant will mix with the sewage, thereby realizing the one-way mixing function of the agent.

[0024] For details regarding the specific structure of the unidirectional flow control mechanism 6, please refer to [link / reference]. Figure 5 and Figure 6 It also includes a component movable cavity 63 disposed inside the second hollow cylinder 61. One end of the second hollow cylinder 61 is provided with a second docking plate 62, which is integrally formed with it and fixedly connected to the first docking plate 53. One end of the component movable cavity 63 is provided with a liquid inlet 64 communicating with the opening of the agent compression chamber 52. The other end of the component movable cavity 63 is provided with multiple liquid outlet holes 65 communicating with the external space. Inside the component movable cavity 63, the second hollow cylinder 61 has a movable valve plate 66 capable of moving axially. At the end of the movable valve plate 66 facing the liquid outlet holes 65, a... In the compressed state of the helical spring 610, the movable valve plate 66 has an annular mounting groove 68 with a concave structure at one end facing the liquid inlet 64. A sealing ring 69 is embedded inside the annular mounting groove 68. The circumferential surface of the movable valve plate 66 has a plurality of concave liquid flow grooves 67. The depth of the annular mounting groove 68 is less than the thickness of the sealing ring 69.

The structural radius of the outer ring of the sealing ring 69 is less than the distance between the liquid flow grooves 67 and the axis of the movable valve plate 66.

[0025] During use and installation, the agent injection channel 55 is connected to the drain port of a storage tank containing precipitant, and the precipitant inside the storage tank can flow into the agent injection channel 55 under its own gravity. Simultaneously, both ends of the central drain pipe 1 are connected to the beginning and end pipes for discharging sewage. Note that after installation, the sewage flows from the driven mixing mechanism 5 to the unidirectional flow control mechanism 6, and finally flows into the sedimentation tank. When the sewage flows inside the sewage flow chamber 2, the turbine blades 59 will rotate under the impact of the water flow. Under the linkage effect of the coupling 57, the spiral blades 510 will rotate accordingly. The precipitant around 10 will tend to flow towards the inlet hole 64 under the drive of the spiral blade 510, and the rotation speed of the turbine fan blade 59 will change with the flow rate of the sewage, thereby using the potential energy of the sewage to generate an adaptive agent mixing function. When the flow pressure of the precipitant is greater than the elastic pressure of the spiral spring 610, the spiral spring 610 will be compressed, and the movable valve plate 66 will move. At this time, the precipitant will sequentially pass through the inlet hole 64, the movement gap of the movable valve plate 66, the liquid flow channel 67, the component moving cavity 63 and multiple drain holes 65 into the central area of ​​the sewage flow. Finally, the precipitant will mix with the sewage.
