A sewage treatment device for a packaging material production plant

Abstract

This utility model discloses a wastewater treatment device for a packaging material production workshop, including an inlet pipe for the main body of the wastewater treatment equipment. A connecting pipe, with a diameter larger than that of the inlet pipe, is connected to the top of the inlet pipe. This utility model uses a geared motor to drive a rotating disk, which in turn drives a sliding strip to slide back and forth via a rotating ring and connecting rod. This, in turn, causes the sliding strip to move up and down via a transmission column, achieving the reciprocating motion of a small conical block and a large conical block. The small conical block, located inside the inlet pipe, can adjust the cross-sectional area of ​​the inlet flow channel and control the wastewater flow rate through its up-and-down movement. Simultaneously, the large conical block, located above the inlet pipe, can assist in intercepting large particles or temporarily blocking the water flow. Furthermore, when the wastewater treatment device is saturated, the large conical block can move downwards to abut the top opening of the inlet pipe, utilizing its larger cross-sectional area to achieve a seal, preventing wastewater overflow or equipment overload.

Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology in packaging material production workshops, specifically to a wastewater treatment device for packaging material production workshops. Background Technology

[0002] In the wastewater treatment process in packaging material production workshops, the wastewater often contains a large amount of suspended solids, colloidal particles, and fibrous impurities. These substances are very likely to accumulate in the inlet pipe of the wastewater treatment device, causing pipe blockage and affecting the normal operation of the wastewater treatment device.

[0003] Currently, to address the issue of inlet pipe blockage, some wastewater treatment devices employ methods such as installing filters inside the inlet pipe to intercept impurities, or maintaining pipe patency through regular manual cleaning. However, the filter-based method is prone to clogging, affecting wastewater inflow efficiency and requiring frequent filter replacements, increasing maintenance costs. Manual cleaning, on the other hand, suffers from issues such as untimely cleaning and high labor intensity, making it difficult to meet the needs of continuous wastewater treatment in packaging material production workshops.

[0004] Furthermore, when wastewater treatment equipment reaches saturation, such as due to excessively high sedimentation tank levels or equipment malfunctions, existing systems typically lack effective inlet pipe sealing measures, failing to promptly stop wastewater inflow. This can lead to wastewater overflow, causing secondary pollution or equipment damage. Existing wastewater treatment systems have independent anti-clogging and sealing functions, resulting in complex structures that not only occupy space but also increase equipment costs and operating energy consumption.

[0005] Therefore, a wastewater treatment device for packaging material production workshops is needed to solve the aforementioned problems. Utility Model Content

A U-shaped slide bar is fixedly connected to the bottom of the transmission column. A fixing bar is slidably connected to the surface of the slide bar, and the fixing bar is fixedly connected to the connecting bar. The maximum sliding distance of the slide bar is less than the length of the fixing bar. A dovetail groove is formed on the surface of the slide bar. A dovetail block is slidably connected inside the dovetail groove. A fixing ring is fixedly connected to the surface of the dovetail block.

A rotating ring is fixedly connected to the surface of the rotating disk, and the inside of the rotating ring is rotatably connected to the connecting rod.

[0008] As a preferred embodiment of this utility model, the bottom and top walls of the dovetail groove are symmetrically provided with mounting grooves. A servo motor is fixedly connected inside the mounting groove. The output shaft of the servo motor is fixedly connected to a rotating shaft. The other end of the rotating shaft is fixedly connected to a threaded block. A stop block is threadedly connected to the surface of the threaded block, and the stop block is slidably connected to the dovetail groove and abuts against the inner wall of the groove.

[0009] As a preferred embodiment of this utility model, the surface of the bearing block is provided with a balancing groove, and a balancing ring is fixedly connected to the inner side of the rotating disk, and the balancing ring is rotatably connected to the balancing groove.

[0010] As a preferred embodiment of this utility model, a protective shell is fixedly connected to the outer side of the bearing block, an annular groove is formed on the inner side of the protective shell, and a ring column is fixedly connected to the outer end of the rotating ring, with the surface of the ring column slidingly connected along the groove wall of the annular groove.

[0011] In a preferred embodiment of this invention, the cross-sectional area of ​​the small conical block is smaller than the diameter of the inlet pipe, and the small conical block is located inside the inlet pipe; the cross-sectional area of ​​the large conical block is larger than the diameter of the inlet pipe, and the large conical block is located above the inlet pipe.

The inner wall of the connecting frame is fixedly connected to a reinforcing rib.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a geared motor to drive a rotating disk to rotate, which in turn drives a sliding strip to slide back and forth via a rotating ring and connecting rod. This, in turn, causes the sliding column to move up and down via a transmission column, thus realizing the reciprocating motion of the small and large conical blocks. The small conical block is located inside the inlet pipe and can adjust the cross-sectional area of ​​the inlet flow channel and control the sewage flow rate by moving up and down.

Utilizing its cross-sectional area, which is larger than the diameter of the inlet pipe, it achieves a seal, preventing sewage overflow or equipment overload.

[0015] 2. This utility model uses a servo motor to drive the threaded block to rotate, causing the abutment to move along the thread direction within the dovetail groove. This changes the relative position of the abutment and the dovetail block, thereby limiting the sliding stroke of the dovetail block. The reciprocating amplitude of the slide bar can be directly controlled by adjusting the movement stroke of the dovetail block, thus precisely controlling the movement distance of the small and large conical blocks to adapt to different processing loads. Specifically, the stroke is increased when the flow rate is high and decreased when the flow rate is low. Attached Figure Description

[0022] 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.

[0023] like Figures 1 to 5 As shown, this utility model provides a wastewater treatment device for a packaging material production workshop, including an inlet pipe 1 for the main body of the wastewater treatment equipment. A connecting pipe 2 is connected to the top of the inlet pipe 1, and the diameter of the connecting pipe 2 is larger than the diameter of the inlet pipe 1. A connecting flange is fixedly connected to the top surface of the connecting pipe 2. A connecting strip 3 is connected to the bottom of the inlet pipe 1. A sliding opening 4 is opened at the top of the connecting strip 3. A sliding column 5 is slidably connected inside the sliding opening 4. A sealing ring is fixedly connected to the top of the sliding opening 4, and the sealing ring is slidably connected to the sliding column 5. A small conical block 6 and a large conical block 7 are fixedly connected sequentially from bottom to top at the top of the sliding column 5. A transmission column 8 is fixedly connected to the bottom of the sliding column 5, and a convex-shaped sliding... A fixed strip 10 is slidably connected to the surface of the slide bar 9, and the fixed strip 10 is fixedly connected to the connecting strip 3. The maximum sliding distance of the slide bar 9 is less than the length of the fixed strip 10. A dovetail groove 11 is opened on the surface of the slide bar 9. A dovetail block 12 is slidably connected inside the dovetail groove 11. A fixed ring 13 is fixedly connected to the surface of the dovetail block 12. A connecting rod 14 is rotatably connected to the surface of the fixed ring 13. A bearing block 15 is fixedly connected to the bottom of the fixed strip 10. A reduction motor 16 is fixedly connected to the outside of the bearing block 15. The output shaft of the reduction motor 16 passes through the bearing block 15 and is fixedly connected to a rotating disk 17. A rotating ring 18 is fixedly connected to the surface of the rotating disk 17, and the inside of the rotating ring 18 is rotatably connected to the connecting rod 14.

[0024] refer to Figure 2 and Figure 5 The bottom and top walls of the dovetail groove 11 are symmetrically provided with mounting grooves. A servo motor 19 is fixedly connected inside the mounting groove. The output shaft of the servo motor 19 is fixedly connected to a rotating shaft 20. The other end of the rotating shaft 20 is fixedly connected to a threaded block 21. A stop block 22 is threadedly connected to the surface of the threaded block 21, and the stop block 22 is slidably connected to the dovetail groove 11 and abuts against the inner wall of the groove.

[0025] As a technical optimization of this utility model, the threaded block 21 is driven to rotate by the servo motor 19, so that the abutment block 22 moves along the thread direction in the dovetail groove 11, changing the relative position of the abutment block 22 and the dovetail block 12, thereby limiting the sliding stroke of the dovetail block 12. The reciprocating amplitude of the slide bar 9 can be directly controlled by adjusting the motion stroke of the dovetail block 12, thereby precisely controlling the movement distance of the small conical block 6 and the large conical block 7 to adapt to different processing loads, that is, increasing the stroke when the flow rate is high and decreasing the stroke when the flow rate is low.

[0026] refer to Figure 4 The surface of the bearing block 15 is provided with a balance groove, and the inner side of the rotating disk 17 is fixedly connected with a balance ring 23, and the balance ring 23 is rotatably connected to the balance groove.

[0027] As a technical optimization of this utility model, the cooperation between the balance ring 23 and the balance groove can counteract the centrifugal force when the rotating disk 17 rotates, reduce vibration and noise, extend the equipment life, and ensure stable and reliable transmission process.

[0028] refer to Figure 1 and Figure 4 A protective shell 24 is fixedly connected to the outer side of the bearing block 15. An annular groove 25 is provided on the inner side of the protective shell 24. A ring column is fixedly connected to the outer end of the rotating ring 18, and the surface of the ring column is slidably connected along the groove wall of the annular groove 25.

[0029] As a technical optimization of this utility model, the protective shell 24 can cover moving parts such as the geared motor 16 and the rotating disk 17, preventing sewage and impurities from entering and causing mechanical failure, thus improving the durability of the equipment. The annular groove 25 and the ring column cooperate to provide a guide track for the rotating ring 18, ensuring the accurate movement trajectory of the connecting rod 14 and avoiding transmission deviation or jamming.

[0030] refer to Figure 2 and Figure 3 The cross-sectional area of ​​the small cone block 6 is smaller than the diameter of the inlet pipe 1, and the small cone block 6 is located inside the inlet pipe 1. The cross-sectional area of ​​the large cone block 7 is larger than the diameter of the inlet pipe 1, and the large cone block 7 is located above the inlet pipe 1.

[0031] As a technical optimization of this utility model, the small conical block 6 adjusts the internal flow area of ​​the inlet pipe 1 by moving up and down, so as to achieve precise flow control, such as throttling or flow restriction. The large conical block 7 only needs to be pressed against the top of the inlet pipe 1 when the equipment is saturated, and forms a sealing surface by utilizing the difference in cross-sectional area. The functions are clearly divided, which improves the control efficiency. At the same time, the conical structure of the small conical block 6 can reduce the retention of impurities in sewage and reduce the risk of blockage.

[0032] refer to Figure 1 and Figure 2The bottom of the bearing block 15 is fixedly connected to an L-shaped connecting frame 26, and the other side of the connecting frame 26 is fixedly connected to the outer shell of the main body of the sewage treatment equipment. The inner wall of the connecting frame 26 is fixedly connected to a reinforcing rib.

[0033] As a technical optimization of this utility model, the connecting frame 26 provides rigid support, which firmly connects the transmission components of the device to the main body of the equipment, avoiding loosening of the components due to long-term vibration. The reinforcing rib enhances the deformation resistance of the connecting frame 26, improves the overall strength and reliability of the device, and adapts to the high load requirements of the industrial workshop environment.

[0034] The working principle and usage process of this utility model are as follows: When using this wastewater treatment device to treat wastewater from packaging materials in a packaging material production workshop, firstly, the device is connected to an external wastewater pipe through the connecting flange at the top of the connecting pipe 2, and the inlet pipe 1 is connected to the main body of the wastewater treatment equipment. Then, the L-shaped connecting frame 26 is used to fix the bearing block 15 to the outer shell of the main body of the wastewater treatment equipment to ensure the stability of the overall structure. Then, according to the wastewater treatment volume requirements, the position of the abutment block 22 is adjusted by the servo motor 19, the sliding stroke of the dovetail block 12 is preset, the rotation speed and angle of the reduction motor 16 are calibrated, and the initial movement of the small cone block 6 and the large cone block 7 is determined. Within the operating range, when the device is in production and use, the geared motor 16 drives the rotating disk 17 to perform circular motion. The rotating ring 18 rotates eccentrically with the rotating disk 17. The circular motion is converted into linear reciprocating motion of the dovetail block 12 in the dovetail groove 11 through the connecting rod 14. Then, the dovetail block 12 drives the slide bar 9 to slide along the fixed bar 10. The transmission column 8 causes the sliding column 5 to move up and down, ultimately controlling the up and down reciprocating motion of the small cone block 6 and the large cone block 7. This not only reduces impurity retention and extends the service life of the equipment by utilizing the cone surface design, but also regulates the sewage flow rate. Then, based on the real-time treatment load (such as the sewage treatment equipment body), the flow rate can be adjusted. (Based on flow sensor data), the servo motor 19 is activated to automatically adjust the position of the abutment block 22, changing the movement amplitude of the small conical block 6 and the large conical block 7. Under high load, the stroke of the dovetail block 12 is increased to increase the sewage inflow; under low load, the stroke of the dovetail block 12 is reduced to decrease the flow rate and avoid energy waste. That is, the servo motor 19 drives the threaded block 21 to rotate, causing the abutment block 22 to move along the dovetail groove 11. The abutment block 22 moves towards the end of the dovetail groove 11, reducing the stroke of the dovetail block 12. At this time, the reciprocating amplitude of the slide bar 9 decreases, thereby reducing the movement range of the small conical block 6 and the large conical block 7. Conversely, the abutment block 22 moves towards the end of the dovetail groove 11. The movement of the middle section increases the stroke of the dovetail block 12, which in turn increases the reciprocating amplitude of the slide bar 9, thereby expanding the range of motion of the small cone block 6 and the large cone block 7. When the liquid level inside the main body of the sewage treatment equipment reaches the upper limit or the treatment capacity is insufficient, the reduction motor 16 is started to drive the large cone block 7 to move downward until its bottom completely touches the top of the inlet pipe 1, blocking the sewage flow. Then, the reduction motor 16 is kept powered to maintain the sealed state. At the same time, the equipment performs internal processing or alarms to prompt the operator. After the processing is completed, the reduction motor 16 rotates in the opposite direction, driving the large cone block 7 to move upward, restoring the inlet channel, and allowing the device to return to normal operation mode.
