[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1

[0029] like Figures 1 to 6 As shown, an omethoate pesticide wastewater treatment device comprises an outer frame 1, and a reaction box 2 is installed on the inner bottom surface of the outer frame 1;

[0030] An L-shaped strip 4 is provided on one side of the outer frame 1, and a transmission rod 9 is provided on one side of the L-shaped strip 4. A servo motor 3 is installed on the surface of the L-shaped strip 4, and the output end of the servo motor 3 passes through the L-shaped strip 4 and is connected to one end of the transmission rod 9. A fixed plate 13 is installed on one side of the L-shaped strip 4 and located on the outside of the transmission rod 9. The bottom surface of one end of the fixed plate 13 is rotatably connected with a rotating shaft 14, and the same pulley transmission group 12 is connected between the rotating shaft 14 and the transmission rod 9. A stirring shaft 17 is provided in the reaction box 2, and one end of the rotating shaft 14 extends into the reaction box 2 and is connected to one end of the stirring shaft 17. A gear 8 is installed on the surface of the transmission rod 9, and a toothed plate 7 is meshingly connected to the surface of the gear 8, and the toothed plate 7 is fixedly installed on one side of the bottom of the outer frame 1.

[0031] The transmission rod 9 is driven to rotate by the servo motor 3, and the gear 8 on the surface of the transmission rod 9 is meshed with the tooth plate 7 fixed on one side of the bottom of the outer frame 1. When the gear 8 rotates, since the tooth plate 7 is fixed, the entire L-shaped strip plate 4 and its accessories can make horizontal reciprocating motion along the strip groove 6 on the surface of the outer frame 1. This horizontal movement drives the position change of the rotating shaft 14 and the stirring shaft 17 connected to the L-shaped strip plate 4. Compared with the traditional fixed-position stirring, this dynamically changing stirring position can more comprehensively cover the space in the reaction box 2. When treating oxydemeton-methyl pesticide wastewater, the stirring shaft 17 can reach different corners and areas in the reaction box 2, effectively avoiding the occurrence of stirring blind spots, allowing the wastewater to be fully mixed at all positions, and improving the mixing uniformity and reaction efficiency.

[0032] Furthermore, a plurality of spiral stirring blades 18 are installed on the surface of the stirring shaft 17 , and the spiral directions of two upper and lower adjacent spiral stirring blades 18 are opposite.

[0033] When the stirring shaft 17 rotates, the spiral stirring blades 18 will push the liquid to flow. Since the spiral stirring blades 18 adjacent to each other rotate in opposite directions, they will generate thrusts in different directions in the axial direction. The upper spiral stirring blades 18 will push the liquid downward, while the lower spiral stirring blades 18 will push the liquid upward. This thrust in opposite directions will cause the liquid to form a strong convection in the axial direction of the stirring shaft 17. When treating omethoate pesticide wastewater, this convection can allow the wastewater to be fully mixed between the upper and lower areas of the reaction box 2, avoiding the phenomenon of upper and lower stratification, so that the added reaction reagents (such as neutralizers, oxidants, etc.) can be quickly and evenly distributed in the entire wastewater system, improving the efficiency and uniformity of the reaction.

[0034] Furthermore, a slider 5 is integrally formed on the top and bottom surfaces of the L-shaped strip 4, and a groove 6 matching the slider 5 is opened on the surface of the outer frame 1. The L-shaped strip 4 is slidably connected to one side surface of the outer frame 1 through the slider 5 and the groove 6.

[0035] The cooperation between the slider 5 and the groove 6 provides a stable supporting structure for the L-shaped strip 4. The slider 5 slides in the groove 6, can withstand these forces and ensure that the L-shaped strip 4 always reciprocates horizontally along a predetermined trajectory, avoiding unstable situations such as deviation, shaking or tilting during movement, thereby ensuring the stability and reliability of the operation of the stirring mechanism, allowing the stirring process to be carried out continuously and effectively, which is conducive to improving the quality and efficiency of wastewater treatment.

[0036] Furthermore, an abutment block 10 is fixedly installed on the bottom surface of the L-shaped strip plate 4 , and a fixed guide rod 11 is slidably connected to the surface of the abutment block 10 . The fixed guide rod 11 is fixedly installed on one side of the reaction box 2 .

[0037] During the operation of the oxydemeton-methyl pesticide wastewater treatment device, the L-shaped strip 4 will perform reciprocating motion in the horizontal direction. The sliding connection between the abutment block 10 and the fixed guide rod 11 provides additional support and guidance for the L-shaped strip 4, ensuring the smoothness of the movement of the L-shaped strip 4, thereby ensuring the uniformity and continuity of stirring.

[0038] Furthermore, a strip groove is provided on the surface of the reaction box 2, and shielding curtains 16 are installed at both ends of the interior of the strip groove. The adjacent ends of the two shielding curtains 16 are commonly connected to a sliding block 15. The sliding block 15 is slidably connected in the strip groove provided on the surface of the reaction box 2, and the rotating shaft 14 is rotatably connected to the surface of the sliding block 15.

[0039] Since the stirring shaft 17 is connected to the L-shaped strip 4 through the rotating shaft 14, and the L-shaped strip 4 will make horizontal reciprocating motion, the position of the stirring shaft 17 will also change accordingly, and the cooperation between the sliding block 15 and the strip groove enables the stirring shaft 17 to flexibly move on the surface of the reaction box 2. The shielding curtains 16 at both ends can be expanded or contracted accordingly with the movement of the sliding block 15, and the sealing state of the strip groove is always maintained. This design can effectively adapt to the dynamic position change of the stirring shaft 17, ensuring that during the entire stirring process, the liquid in the reaction box 2 will not leak due to the change in the position of the stirring shaft 17, and will not affect the normal movement of the stirring shaft 17.

[0040] Embodiment 2

[0041] Improvements based on Example 1:

[0042] Furthermore, two diluent barrels 19 are symmetrically installed on the surface of the outer frame 1, and the bottoms of the two diluent barrels 19 are connected to a feed pipe 20, one end of the feed pipe 20 passes through the outer frame 1 and the reaction box 2 in sequence and extends into the reaction box 2.

[0043] The two symmetrically installed diluent barrels 19 provide sufficient diluent storage capacity for the treatment of omethoate pesticide wastewater. During the treatment process, the diluent is directly transported to the reaction box 2 through the bottom-connected feed pipe 20. This design makes the operation of adding diluent very convenient.

[0044] Furthermore, a control panel 22 is provided on one side of the feed tube 20 , a waist groove 24 adapted to the control panel 22 is provided on the surface of the feed tube 20 , the feed tube 20 is slidably connected in the waist groove 24 provided on the surface of the feed tube 20 , and a through groove 23 is provided on the surface of the control panel 22 .

[0045] The through slot 23 on the control plate 22 is matched with the inner diameter of the feeding tube 20. By sliding the control plate 22 so that the through slot 23 and the inner diameter of the feeding tube 20 are partially overlapped or completely offset, the flow rate of the diluent can be accurately adjusted.

[0046] Furthermore, a wedge plate 21 is installed on one side surface of the L-shaped strip plate 4, and one end of the control plate 22 close to the wedge plate 21 is in an arc shape.

[0047] When the L-shaped strip 4 reciprocates in the horizontal direction, the wedge plate 21 on one side thereof will interact with the arc-shaped end of the control plate 22 as it moves. During the treatment of oxydemeton-methyl pesticide wastewater, as the position of the stirring shaft 17 changes, the wedge plate 21 will periodically push the control plate 22, causing the overlapping area between the through groove 23 and the inner diameter of the feed pipe 20 to change, thereby automatically controlling the intermittent delivery of the diluent, which reduces the need for manual operation and improves the degree of automation and work efficiency of the treatment process.

[0048] Furthermore, a through hole is opened on one end surface of the control board 22, and a T-shaped rod 25 is slidably connected in the through hole, a connecting frame 27 is installed on one end of the T-shaped rod 25, and the connecting frame 27 is fixedly installed on one side surface of the discharge pipe 20. A spring 26 is sleeved on the outer surface of the T-shaped rod 25, one end of the spring 26 abuts against the connecting frame 27, and the other end of the spring 26 abuts against one side surface of the control board 22.

[0049] The setting of the spring 26 enables the control board 22 to automatically reset after being pushed by the wedge plate 21 and changing its position. During the treatment of oxydemeton-methyl pesticide wastewater, each time the wedge plate 21 triggers the control board 22 to open the through slot 23 to release a certain amount of diluent, the spring 26 can close the through slot 23 in time to prevent the diluent from continuously and excessively flowing into the reaction box 2, thereby ensuring that the amount of diluent released each time is accurate, maintaining the stability of the reaction environment and the efficiency of the reaction process.

[0050] Furthermore, the width of the control plate 22 is larger than the inner diameter of the feed tube 20 and smaller than the outer diameter of the feed tube 20 , and the size of the through slot 23 is adapted to the inner diameter of the feed tube 20 .

[0051] The width of the control plate 22 is greater than the inner diameter of the feed tube 20, which can ensure that the control plate 22 can completely cover the inner hole of the feed tube 20 at any position. When the through groove 23 is misaligned with the inner diameter of the feed tube 20, the control plate 22 can effectively block the feed tube 20 to prevent leakage of the diluent. The size of the through groove 23 is adapted to the inner diameter of the feed tube 20, so that by controlling the overlapping area of ​​the through groove 23 and the inner diameter of the feed tube 20, the flow rate of the diluent can be accurately controlled. When a larger flow rate of diluent is required, the through groove 23 can be completely overlapped with the inner diameter of the feed tube 20; when a smaller flow rate is required, the through groove 23 and the inner diameter of the feed tube 20 can be partially overlapped. The inner diameter of the feed pipe 20 is sufficient; when the diluent does not need to flow in, the two are completely staggered. This precise flow control method can flexibly adjust the amount of diluent according to the actual situation of the wastewater, such as the volume, concentration and treatment stage requirements of the wastewater, thereby improving the effect and efficiency of wastewater treatment. Since the width of the control plate 22 is smaller than the outer diameter of the feed pipe 20, it can slide stably in the waist groove 24 and will not interfere with the structure around the feed pipe 20 due to being too wide. In the process of adjusting the overlapping area of ​​the through groove 23 and the inner diameter of the feed pipe 20, the control plate 22 can move smoothly, thereby achieving stable flow regulation. This helps to avoid sudden changes in flow caused by the unsmooth movement of the control plate 22, ensures the stability of the diluent flow regulation process, and provides a stable diluent addition environment for the treatment of oxydemeton-methyl pesticide wastewater, which is conducive to the smooth progress of chemical reactions.

[0052] Working principle: When in use, first, inject the wastewater containing omethoate pesticide components into the reaction box 2, then start the servo motor 3, so that the servo motor 3 rotates forward and reversely, and the servo motor 3 drives the transmission rod 9 to rotate. Since the gear 8 on the surface of the transmission rod 9 is meshed and connected with the toothed plate 7 fixed on one side of the bottom of the outer frame 1, the gear 8 rolls on the toothed plate 7, thereby driving the entire L-shaped strip plate 4 and its attached parts to make horizontal reciprocating motion along the strip groove 6 on the surface of the outer frame 1. At the same time, the transmission rod 9 drives the rotating shaft 14 to rotate through the pulley transmission group 12, and the rotating shaft 14 further drives the stirring shaft 17 to rotate in the reaction box 2 to stir the wastewater;

[0053] A plurality of spiral stirring blades 18 are installed on the stirring shaft 17, and the spiral directions of two spiral stirring blades 18 adjacent to each other are opposite. This design makes the stirring effect more significant. During the stirring process, the wastewater forms an up-and-down churning water flow under the action of the spiral stirring blades 18, which promotes the mixing of the wastewater. At the same time, the wastewater at different positions in the reaction box 2 can be fully stirred, avoiding the problem of insufficient reaction caused by uneven stirring.

[0054] While stirring, the diluent is intermittently added: the diluent in the two diluent barrels 19 symmetrically installed on the outer frame 1 enters the reaction box 2 through the discharge pipe 20. When the L-shaped strip 4 moves horizontally, the wedge plate 21 installed on one side of the surface will gradually approach the control board 22 as it moves. Since the end of the control board 22 close to the wedge plate 21 is arc-shaped, when the wedge plate 21 contacts the arc-shaped end of the control board 22, it will push the control board 22 to slide on the T-shaped rod 25, compressing the spring 26, so that the through groove 23 on the control board 22 coincides with the inner diameter of the discharge pipe 20. At this time, the diluent starts to flow from the discharge pipe 20 into the reaction box 2;

[0055] As the L-shaped strip 4 continues to move, the wedge plate 21 gradually leaves the control plate 22. Under the elastic force of the spring 26, the control plate 22 returns to its original position, the through groove 23 is offset from the inner diameter of the feed pipe 20, and the diluent stops flowing in. In this way, the intermittent addition of the diluent is achieved. This intermittent addition method can accurately control the amount and timing of the diluent addition according to the stirring process and the actual situation of the wastewater, avoiding problems such as reaction imbalance or overreaction that may be caused by continuous large-scale addition of diluent;

[0056] During the entire treatment process, the position of the stirring shaft 17 in the reaction box 2 is continuously changed through the forward and reverse rotation of the servo motor 3, so that the wastewater in each area of ​​the reaction box 2 can be fully stirred and mixed. At the same time, the intermittent addition of diluent further improves the treatment effect of the omethoate pesticide wastewater. After a period of treatment, the wastewater in the reaction box 2 is tested, and various pollutant indicators are significantly reduced, achieving the expected treatment effect.

[0057] It should be noted that the reaction box 2 is made of transparent material, and the operator can directly observe the reaction phenomena such as the color change of the wastewater, whether precipitation is produced, the generation of bubbles, etc. One side of the reaction box 2 is connected to a discharge pipe (not shown in the figure) for centralized discharge of the treated wastewater.

[0058] It should be noted that the pulley transmission group 12 is mainly composed of two pulleys and a belt, and the two pulleys are connected to the transmission rod 9 and the rotating shaft 14 respectively.

[0059] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
