Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater treatment device for insecticide preparation. Background Technology

[0002] Wastewater generated during pesticide preparation is complex, containing large amounts of organic matter, heavy metals, and toxic and harmful substances. It requires the use of wastewater treatment equipment to treat the wastewater. The traditional method for removing turbidity and suspended solids from wastewater used in pesticide preparation is to add flocculants.

[0003] According to application number 201921181067.4, a water treatment electrocoagulation reactor is disclosed. Iron ions are electrolyzed from iron electrode plates and introduced into the water. Under the action of electric field and aeration nozzle, water molecules dissociate to produce hydrogen ions and hydroxide ions. The iron ions combine with the hydroxide ions dissolved in the water to generate ferric hydroxide and other highly active adsorption groups, which adsorb suspended solids, colloidal particles, high molecular weight organic matter and other impurities in the water and settle together. It can effectively reduce the turbidity and color of water and remove suspended solids, colloids, organic matter and other impurities, thus improving the treatment effect.

[0004] The aforementioned equipment removes turbidity and suspended solids from wastewater through electrocoagulation, effectively solving the scaling problem. However, it lacks a pretreatment structure for wastewater. The wastewater has a complex composition, and heavy inorganic particles such as sand and pebbles directly enter the flocculation tank, increasing wear on subsequent equipment and affecting treatment efficiency. Furthermore, the stirring structure in the aforementioned equipment has a limited stirring range, which is not conducive to reaction, adsorption, and aggregation effects. Therefore, we propose a wastewater treatment equipment for pesticide preparation to address the shortcomings of the existing equipment. Utility Model Content

Detailed Implementation

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.

[0027] like Figure 1-5 As shown, this utility model provides a technical solution: a wastewater treatment device for pesticide preparation, including a flocculation tank 1, a support 2 fixedly connected to the top of the flocculation tank 1, an inlet pipe 3 fixedly connected to the outside of the support 2, a rotating motor 4 fixedly installed at the top of the support 2, a connecting rod 5 fixedly connected to the output shaft of the rotating motor 4, a filter cylinder 6 fixedly connected to the bottom of the connecting rod 5, a filter assembly 7 provided inside the filter cylinder 6, a stirring assembly 8 provided inside the flocculation tank 1, a shell 9 fixedly connected to the outside of the flocculation tank 1, an aeration pipe 10 fixedly connected inside the flocculation tank 1, an aeration pump 11 fixedly installed at one end of the aeration pipe 10, several aeration nozzles 12 fixedly connected to the surface of the aeration pipe 10, a grid 13 fixedly connected to the inner wall of the flocculation tank 1, several iron electrode plates 14 fixedly installed at the top of the grid 13, and an outlet pipe 15 fixedly connected to the outside of the flocculation tank 1.

[0028] When in use, sewage is discharged from the inlet pipe 3 and first flows into the filter cylinder 6. The inorganic particles of the sewage are intercepted and filtered through the filter component 7 to reduce the wear of inorganic particles on subsequent equipment. After preliminary filtration, the sewage enters the flocculation tank 1. Iron ions are electrolyzed out and enter the water through the iron electrode plate 14. By starting the aeration pump (11) and cooperating with the aeration pipe (10) for pneumatic delivery, the aeration nozzle (12) can be aerated. Under the action of electric field and aeration nozzle 12, the sewage can be treated by electrocoagulation. During the reaction process, the sewage is stirred by the stirring component 8 to increase the reaction, adsorption and aggregation effects.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the filter assembly 7 includes a fixing ring 701, a washer 702, a filter screen 703, a fixing frame 704, a limiting rod 705, a support spring 706, and a guide rod 707. The outer side of the fixing ring 701 is fixedly connected to the inner wall of the filter cylinder 6. The outer side of the washer 702 is fixedly connected to the outer side of the fixing ring 701. The outer side of the filter screen 703 is fixedly connected to the outer sides of the washer 702 and the fixing ring 701. Both ends of the fixing frame 704 are fixedly connected to the inner wall of the filter cylinder 6. The top end of the limiting rod 705 is fixedly connected to the bottom end of the washer 702, and the bottom end of the limiting rod 705 penetrates the surface of the fixing frame 704. The top end of the support spring 706 is fixedly connected to the bottom end of the washer 702, and the bottom end of the support spring 706 is fixedly connected to the top end of the fixing frame 704. There are two guide rods 707. The top end of the guide rod 707 is fixedly connected to the outer side of the filter screen 703, and one end of the guide rod 707 penetrates the surface of the fixing frame 704.

[0030] The wastewater can be pretreated by the filter assembly 7, which intercepts and filters larger inorganic particles in the wastewater, reducing wear on subsequent equipment caused by inorganic particles. The wastewater first flows into the filter cylinder 6 and falls onto the filter screen 703. The filter screen 703 intercepts and filters the inorganic particles in the wastewater. The limiting rod 705 and the support spring 706 can play a buffering role to resist the impact of water flow and avoid damage to the installation components of the filter screen 703 caused by strong impact.

[0031] like Figure 1 , Figure 2 and Figure 4As shown, the stirring assembly 8 includes a stirring shaft 801, stirring blades 802, a drive motor 803, a first gear 804, a second gear 805, a connecting shaft 806, and a transmission belt 807. There are two stirring shafts 801. Both ends of the stirring shafts 801 are rotatably connected to the inner wall of the flocculation tank 1. The stirring blades 802 are fixedly connected to the outer side of the stirring shafts 801. One end of the drive motor 803 is fixedly connected to the outer side of the housing 9. The outer side of the first gear 804 is fixedly connected to the output shaft of the drive motor 803. The outer side of the connecting shaft 806 is fixedly connected to one end of one of the stirring shafts 801, and one end of the connecting shaft 806 is fixedly connected to one end of the other stirring shaft 801. The transmission belt 807 is sleeved between the connecting shaft 806 and the output shaft of the drive motor 803, and the connecting shaft 806 and the output shaft of the drive motor 803 are rotatably connected through the transmission belt 807.

[0032] The wastewater can be stirred by the set stirring component 8. By starting the drive motor 803, and cooperating with gear 1 804, gear 2 805 and transmission belt 807, the two stirring shafts 801 can rotate in different directions to stir and mix. The two stirring shafts 801 stir at the same time, with a large stirring range and high stirring efficiency, which can increase the reaction, adsorption and aggregation effects.

[0033] Working principle: During use, sewage is discharged from the inlet pipe 3 and first flows into the filter cylinder 6, falling onto the filter screen 703. The filter screen 703 intercepts and filters the inorganic particles of the sewage, reducing the wear of inorganic particles on subsequent equipment and achieving the effect of pre-treatment of sewage. When the injected water continuously impacts the filter screen 703, the limiting rod 705 and the support spring 706 can play a buffering role to resist the impact of the water flow and avoid damage to the installation components of the filter screen 703 caused by strong impact. At the same time, during the buffering process, the filter screen 703 can drive the limiting rod 705 and the guide rod 707 to slide within the fixed frame 704, thereby limiting the filter screen 703, increasing stability, and making it more stable when facing the impact of water flow.

[0034] After preliminary filtration, the wastewater enters the flocculation tank 1. Iron ions are electrolytically released into the water through the iron electrode plate 14. Under the action of the electric field and the aeration nozzle 12, the wastewater can be treated by electrocoagulation. By starting the drive motor 803, the gear 1 804 can be rotated. The gear 2 805 can drive the stirring shaft 801 and stirring blade 802 on one side to rotate. At the same time, the transmission belt 807 can drive the stirring shaft 801 and stirring blade 802 on the other side to rotate. This allows the two stirring shafts 801 to rotate in different directions for stirring and mixing. The stirring range is large and the stirring efficiency is high, which can increase the reaction, adsorption and aggregation effects.

[0035] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0036] 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.
