Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater treatment system for pesticide workshops. Background Technology
[0002] Existing pesticide wastewater treatment filtration equipment generally adopts a single-station filter cartridge design, which has two major drawbacks when replacing the filter cartridge: First, the lack of a filter cartridge positioning support structure leads to insufficient installation accuracy. In traditional equipment, filter cartridges are often directly connected to pipes via flanges or threads, lacking dedicated limiting support components. During replacement, the coaxiality of the filter cartridge and the inlet / outlet pipes must be manually calibrated, often resulting in filter cartridge misalignment, forming annular flow deviation, reducing the effective utilization rate of the filter media, and aggravating local wear. Second, the cumbersome filter cartridge replacement process leads to long-term filtration shutdowns. Existing equipment requires sequential steps such as closing valves, emptying the wastewater in the tank, removing the top cover, taking out the old filter cartridge, cleaning the installation position, and refilling the new filter cartridge. Moreover, the entire filtration system is completely shut down during the replacement period. Wastewater discharge from pesticide workshops is continuous, and long-term shutdowns not only lead to excessive wastewater retention but also require additional emergency treatment costs. In addition, existing equipment lacks a filter cartridge pre-positioning and quick switching mechanism. When installing a new filter cartridge, the position needs to be repeatedly adjusted to match the connection port, which further prolongs the operation time. At the same time, installation deviations can easily lead to the filter media being installed in the wrong direction or not sealing properly, resulting in a decrease in filtration accuracy and even causing environmental risks of pollutant leakage. Therefore, developing a filter cartridge installation structure that combines precise positioning support and quick replacement is of great practical significance for improving the continuity and stability of pesticide wastewater treatment. Summary of the Invention
[0003] The purpose of this utility model is to provide a wastewater treatment system for pesticide workshops, in order to solve the problems mentioned in the background art, such as the lack of effective positioning support when replacing filter elements in existing pesticide workshop wastewater treatment filtration equipment, resulting in insufficient installation accuracy, cumbersome replacement process, lack of quick switching mechanism, and consequently, long-term stagnation of filtration operations, excessive wastewater retention, and environmental risks of pollutant leakage.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment system for a pesticide workshop, including an installation frame, an inlet pipe, an outlet pipe and a dosing pipe are provided above the installation frame, and a valve is fixedly installed on the outer surface of one end of each of the inlet pipe, outlet pipe and dosing pipe through a pipe, and a connecting cover is fixedly installed on the other end of the valve, and a filter element is provided between the two connecting covers; A mounting plate is fixedly installed on the lower outer surface of the mounting bracket, and a switching motor is fixedly installed on the lower surface of the mounting plate. The upper end of the output shaft of the switching motor passes through the upper surface of the mounting plate, and a central column is fixedly connected to the upper end of the output shaft of the switching motor. A sliding plate is fixedly installed on the outer surface of the central column, and a fixed half-ring is slidably connected to the outer surface of the sliding plate. A rotating movable half-ring is installed at one end of the fixed half-ring. A plug-in barrel is fixedly installed on the upper surface of the fixed half-ring and the movable half-ring located at the lower end of the sliding plate. A plug-in post is fixedly installed on the lower surface of the fixed half-ring and the movable half-ring located at the upper end of the sliding plate. One end of the fixed half-ring passes through the outer surface of the sliding plate, and a limit block is fixedly connected to the end of the fixed half-ring that passes through the sliding plate. A sliding cylinder is fixedly installed on the outer surface of the middle section of the sliding plate, and a sliding locking block is installed at one end of the sliding cylinder.
[0005] Preferably, the sliding plate is set at equal angles on the outer surface of the central column, and the outer surface of the sliding plate is set vertically.
[0006] By adopting the above technical solution, it is ensured that the filter element it carries always maintains a vertical posture when the sliding plate rotates with the central column, avoiding the docking deviation with the connecting cover due to tilting. At the same time, it can realize the rapid switching of multiple filter elements distributed in the circumference, laying the structural foundation for replacing filter elements without long-term downtime in the future.
[0007] Preferably, the fixed half-ring and the movable half-ring are concentrically arranged, and the opposite ends of the fixed half-ring and the movable half-ring are attached to each other, and the inner surfaces of the fixed half-ring and the movable half-ring are attached to the inner surface of the filter element.
[0008] By adopting the above technical solution, a full circumferential clamping of the filter element is formed, which completely solves the problem of "filter element displacement caused by lack of positioning support" in traditional equipment, avoids flow deviation in the annular gap, improves the effective utilization rate of filter media, and at the same time reduces local wear of the filter element and extends its service life.
[0009] Preferably, the fixed half-ring at the upper end of the sliding plate and the fixed half-ring at the lower end of the sliding plate have different opening directions, and the opening directions of the fixed half-ring at the upper end of the sliding plate and the fixed half-ring at the lower end of the sliding plate are designed to be perpendicular to each other.
[0010] By adopting the above technical solution, the situation of simultaneous loosening of the upper and lower fixed semi-rings due to the same opening direction can be avoided, further enhancing the constraint on the semi-ring structure and ensuring that the filter element is always in a stable clamping state during installation and switching.
[0011] Preferably, the plug-in barrel and the plug-in post are configured in a one-to-one correspondence, and the plug-in barrel and the plug-in post are snap-fitted together.
[0012] By adopting the above technical solution, it is ensured that the upper and lower semi-rings remain closed while maintaining a constant relative height, preventing the filter element from falling off due to accidental opening of the movable semi-ring caused by vibration.
[0013] Preferably, a spring connects the locking block and the sliding cylinder, and the locking block has a mountain-shaped design, with both ends of the locking block engaging with the upper and lower limit blocks respectively.
[0014] Using the above technical solution, the spring provides elastic pre-tightening force to the locking block towards the limiting block. The mountain-shaped locking block can axially limit the upper and lower fixed semi-rings and movable semi-rings, preventing the semi-ring structure from loosening when the sliding plate rotates or slides, further ensuring the sealing performance between the filter element and the connecting cover, and reducing the risk of pollutant leakage.
[0015] Compared with the prior art, the beneficial effects of this utility model are: the wastewater treatment system for pesticide workshops: 1. By cooperating with the central column and the sliding plate, when the central column is rotated by the switching motor, the circumferentially distributed sliding plate can be rotated synchronously, so that the position of the spare filter element and the filter element to be replaced can be quickly switched. Compared with the shortcomings of existing equipment that requires the machine to be stopped to replace the filter element, this solution does not require shutting down the entire filtration system. The filter element can be replaced simply by switching the position of the sliding plate and closing the valve on the corresponding connecting cover of the filter element, which significantly improves the continuity of sewage treatment.
[0016] 2. When the fixed half-ring and the movable half-ring are closed, they can completely fit the outer surface of the filter element, forming a stable clamping structure. This effectively avoids the error of manual calibration of coaxiality. This structure can ensure that the filter element is accurately connected to the inlet pipe and outlet pipe, preventing the phenomenon of "filter element misalignment causing annular gap flow deviation" in the background technology. This improves the effective utilization rate of filter media, reduces local wear, and extends the service life of the filter element. 3. The locking block and the limiting block engage to axially limit the upper and lower fixed half rings and movable half rings, preventing the half ring structure from loosening when the sliding plate slides. On the other hand, the locking design of the plug barrel and the plug post ensures that the two sets of half rings with 90-degree openings remain closed with a constant relative height, avoiding the filter element from falling off due to accidental opening of the half rings.

Detailed Implementation
[0019] 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.
[0020] Please see Figures 1-6 This utility model provides a technical solution: a wastewater treatment system for pesticide workshops.
[0021] Example 1: This example discloses: mounting frame 1, with an inlet pipe 2, an outlet pipe 3 and a dosing pipe 4 above the mounting frame 1. A valve 5 is fixedly installed on the outer surface of one end of each of the inlet pipe 2, outlet pipe 3 and dosing pipe 4 through a pipe, and a connecting cover 6 is fixedly installed on the other end of the valve 5. A filter element 7 is provided between the two connecting covers 6. Mounting frame 1 serves as the core load-bearing component of the entire system. Bolts secure the inlet pipe 2, outlet pipe 3, and dosing pipe 4 to the top of the frame, ensuring that the components do not shake during operation. This provides a stable structural reference for subsequent filtration operations and avoids misalignment of the liquid path due to component displacement. Wastewater containing pesticide residues and suspended impurities generated in the pesticide workshop is first treated according to the type of pollutants in the wastewater, such as organophosphorus and pyrethroid pesticides. The corresponding treatment agents, such as alkaline hydrolysate and activated carbon suspension, are precisely added to the connecting cover 6 connected to valve 5 through dosing pipe 4 in conjunction with inlet pipe 2. This allows wastewater and agents to be injected into filter element 7 simultaneously. The opening and closing degree can be adjusted manually or automatically to control the liquid flow rate of each pipeline, preventing excessive flow from clogging filter element 7 or insufficient flow from affecting treatment efficiency. Alternatively, the corresponding pipeline can be closed before replacing filter element 7 to prevent wastewater leakage. The other end of the valve 5 is fixedly installed with the connecting cover 6. The two ends of the filter element 7 are tightly connected to the inner wall of the connecting cover 6. Wastewater enters the connecting cover 6 through the valve 5 and then flows through the filter media layer of the filter element 7 at a uniform speed. The filter media intercepts suspended impurities in the wastewater and adsorbs some pesticide residues. The filtered wastewater that meets the standards is finally discharged from the system through the outlet pipe 3, completing the basic filtration operation.
[0022] Example 2: This example is based on Example 1: A mounting plate 8 is fixedly installed on the lower outer surface of the mounting bracket 1, and a switching motor 9 is fixedly installed on the lower surface of the mounting plate 8. The upper end of the output shaft of the switching motor 9 passes through the upper surface of the mounting plate 8, and a central column 10 is fixedly connected to the upper end of the output shaft of the switching motor 9. A sliding plate 11 is fixedly installed on the outer surface of the central column 10, and a fixed half-ring 12 is slidably connected to the outer surface of the sliding plate 11. A rotating movable half-ring 13 is installed at one end of the fixed half-ring 12. A plug-in barrel 14 is fixedly installed on the upper surface of the fixed half ring 12 and the movable half ring 13 located at the lower end of the sliding plate 11. A plug-in post 15 is fixedly installed on the lower surface of the fixed half ring 12 and the movable half ring 13 located at the upper end of the sliding plate 11. One end of the fixed half ring 12 penetrates the outer surface of the sliding plate 11, and a limit block 16 is fixedly connected to one end of the fixed half ring 12 penetrating the sliding plate 11. A sliding cylinder 17 is fixedly installed on the outer surface of the middle section of the sliding plate 11, and a sliding block 18 is installed at one end of the sliding cylinder 17. The sliding plate 11 is set at equal angles on the outer surface of the central column 10, and the outer surface of the sliding plate 11 is set vertically. The fixed half ring 12 and the movable half ring 13 are concentrically arranged, and the opposite ends of the fixed half ring 12 and the movable half ring 13 are attached to each other, and the inner surfaces of the fixed half ring 12 and the movable half ring 13 are attached to the inner surface of the filter element 7. The fixed half ring 12 at the upper end of the sliding plate 11 and the fixed half ring 12 at the lower end of the sliding plate 11 have different opening directions, and the opening directions of the fixed half ring 12 at the upper end of the sliding plate 11 and the fixed half ring 12 at the lower end of the sliding plate 11 are designed to be perpendicular to each other. The plug-in barrel 14 and the plug-in post 15 are configured in a one-to-one correspondence, and the plug-in barrel 14 and the plug-in post 15 are engaged and installed. A spring connects the locking block 18 to the sliding cylinder 17. The locking block 18 is designed in the shape of a mountain, and both ends of the locking block 18 are engaged with the upper and lower limit blocks 16 respectively. After the switching motor 9 starts, its output shaft passes through the upper surface of the mounting plate 8 and is fixed to the lower end of the central column 10 by a key, driving the central column 10 to rotate around its own axis. The sliding plate 11 is fixedly installed on the outer surface of the central column 10 at angles such as 90° and 120°, and the outer surface of the sliding plate 11 is set vertically. This ensures that when the sliding plate 11 rotates with the central column 10, the filter element 7 it carries always maintains a vertical posture, avoiding the docking deviation with the connecting cover 6 due to tilting. Through the cooperation of the central column 10 and the sliding plate 11, multiple filter elements 7 distributed in the circumference can be quickly switched without shutting down the entire filtration system. Only the valve 5 corresponding to the filter element 7 to be replaced needs to be closed, solving the sewage retention problem caused by the existing equipment requiring "stopping the machine to replace the filter element 7". A sliding groove is provided on the outer surface of the sliding plate 11. The fixed half ring 12 is slidably connected to the sliding plate 11 through the sliding groove. One end of the fixed half ring 12 is fitted with a rotatable movable half ring 13 via a hinge. The fixed half ring 12 and the movable half ring 13 are concentrically arranged, and their opposite ends are fastened together by a snap fastener. Their inner surfaces are tightly fitted with the outer surface of the filter element 7, forming a full circumferential clamping of the filter element 7. This completely solves the problem of "lack of positioning support causing the filter element 7 to shift" in traditional equipment, avoids flow deviation in the annular gap, and improves the effective utilization rate of the filter material. The fixed half-ring 12 at the upper end of the sliding plate 11 and the fixed half-ring 12 at the lower end are designed to be perpendicular to each other, such as the upper opening facing left and the lower opening facing forward. They are connected to the plug-in barrel 14 welded to the upper surface of the lower fixed half-ring 12 and the movable half-ring 13, and the plug-in post 15 welded to the lower surface of the upper fixed half-ring 12 and the movable half-ring 13. The plug-in barrel 14 and the plug-in post 15 are installed in a one-to-one correspondence. This can ensure that the upper and lower half-rings remain closed while the relative height remains unchanged, and prevent the movable half-ring 13 from accidentally opening due to vibration, which would cause the filter element 7 to fall off. One end of the fixed half-ring 12 penetrates the outer surface of the sliding plate 11 and is fixedly connected to the limiting block 16. This limits the sliding range of the fixed half-ring 12 on the sliding plate 11 and prevents the fixed half-ring 12 from detaching from the groove. A fixed sliding cylinder 17 is welded to the outer surface of the middle section of the sliding plate 11. A guide hole is provided at one end of the sliding cylinder 17. The locking block 18 is slidably connected to the sliding cylinder 17 through the guide hole. A spring is sleeved between the locking block 18 and the sliding cylinder 17. The spring provides the locking block 18 with an elastic pre-tightening force toward the limiting block 16. The locking block 18 has a mountain-shaped design. Its upper and lower ends are respectively engaged with the limiting blocks 16 on the upper and lower sides. This forms an axial limit on the upper and lower fixed half-rings 12 and the movable half-rings 13, preventing the half-ring structure from loosening when the sliding plate 11 rotates or slides. This further ensures the sealing of the filter element 7 and the connecting cover 6 and reduces the risk of pollutant leakage. When switching filter element 7: Close valves 5 on the inlet pipe 2, outlet pipe 3, and dosing pipe 4 corresponding to the filter element 7 to be replaced, and disassemble the connection between the connecting cover 6 and the filter element 7. Start the switching motor 9, and the central column 10 drives the sliding plate 11 to rotate, turning the spare filter element 7 to the working position. After the spare filter element 7 is in place and installed, turn off the switching motor 9, open the corresponding valve 5, and the sewage enters through the inlet pipe 2. The dosing pipe 4 adds the agent, and the sewage enters the filter element 7 through the connecting cover 6 for filtration. After filtration, the sewage is discharged from the outlet pipe 3, realizing continuous filtration operation. At the same time, the old filter element 7 can be disassembled and replaced at the maintenance position without affecting the overall operation of the system.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
