Description

Technical Field

[0001] The present invention relates to the technical field of coal wastewater treatment, in particular to a high-efficiency treatment device for coal-containing wastewater. Background Art

[0002] Coal washing wastewater contains a large amount of suspended matter, coal slime and mud sand, so it is also called coal slime water. The suspended matter concentration of untreated coal slime water can reach more than 5000 mg / L. Since coal itself is hydrophobic, some tiny coal powders in the coal washing wastewater are particularly stable in water. Some ultrafine coal powders are suspended in water and will not naturally settle even after being left standing for several months. Coal washing wastewater is a weakly alkaline colloidal system. Its main characteristics are that the surface of the particles carries a strong negative charge, and the concentration and CODcr concentration are very high; the content of fine particles is high; the viscosity is high; the sludge specific resistance is large, and the filtration performance is poor. The coal-containing wastewater generated by the existing coal transportation system is collected in the coal-containing wastewater sedimentation tank, and after treatment, it is returned to the coal water clear water tank for recycling; Publication number CN114632374B discloses "a highly efficient treatment device for coal-containing wastewater, relating to the technical field of coal-containing wastewater treatment, comprising: a sedimentation tank, a fixed frame fixedly connected to the top of the sedimentation tank, a driving mechanism mounted on the top of the fixed frame; a reciprocating mechanism; a stirring mechanism for stirring; and a rotating mechanism mounted on the bottom of the inner wall of the sedimentation tank, the rotating mechanism being used to drive the stirring mechanism to rotate. According to the invention, when a flow meter detects that the amount of coal-containing wastewater in the sedimentation tank has reached the operating requirements of the driving motor, the driving mechanism starts to stir the water to a certain extent. The operation of the driving mechanism drives the stirring mechanism upward through the reciprocating mechanism, causing the stirring mechanism to rotate and return to the bottom position under the action of the rotating mechanism, thereby preventing sedimentation at the bottom of the sedimentation tank and preventing coal slime from adhering to the side walls of the sedimentation tank and affecting subsequent use and wastewater treatment." However, the aforementioned patent also has the following drawbacks: For example, the bidirectional screw groove is prone to clogging, and during use, coal sludge particles easily enter the bidirectional screw groove, hindering the sliding of the connecting rod and reducing stirring efficiency. Furthermore, the patent relies solely on the rotation and reciprocating scraping of the stirring blade, which cannot effectively break the adhesion between the coal sludge and the pool wall. High-viscosity coal sludge easily forms a stubborn adhesion layer on the side wall, gradually thickening and hardening, resulting in low wall cleaning efficiency.

[0003] Therefore, it is urgent to improve the above patent to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide an efficient treatment device for coal-containing wastewater, which makes stirring more sufficient by combining stirring with up and down reciprocating motion, thereby improving the mixing effect of coal-containing wastewater and treatment reagents, accelerating the precipitation reaction, and improving the wastewater treatment efficiency. At the same time, by coordinating the reciprocating structure with the knocking structure, scaling of the inner wall of the sedimentation tank is avoided, thereby ensuring the normal use and efficient operation of the sedimentation tank and extending the service life of the equipment.

[0005] In order to achieve the above-mentioned object, the main technical solution adopted by the present invention is as follows: an efficient treatment device for coal-containing wastewater includes a sedimentation tank and a horizontal plate fixed inside the sedimentation tank, wherein the sedimentation tank is provided with a stirring assembly and a driving structure; The stirring assembly consists of a stirring shaft, a first stirring rod and a second stirring rod; The driving structure is composed of a driving motor, a transmission sleeve, a gear part and an abutment part, and a connecting part is provided between the stirring shaft and the abutment part; The stirring shaft is provided with a reciprocating structure extending outward therefrom, and the first stirring rod and the second stirring rod are provided with a knocking structure used in conjunction with the reciprocating structure; The reciprocating structure includes a reciprocating shaft arranged inside the stirring shaft, a connecting structure extending to the inside of the first stirring rod is arranged on the outside of the reciprocating shaft, the connecting structure includes a first connecting shaft and a second connecting shaft, a shaft is detachably installed inside the second connecting shaft, a first ball is rotatably installed on one end of the shaft, and a wave groove is opened inside the stirring shaft to roll with the first ball; The knocking structure includes a slide and an elastic member arranged inside the second stirring rod, a hook is provided between the slide and the elastic member, one end of the first connecting shaft is connected to the elastic member, and a knocking block is fixed on the side of the slide away from the elastic member.

[0006] This application adopts the above-mentioned technical solution, and makes the stirring more complete by combining stirring with up and down reciprocating motion, thereby improving the mixing effect of coal-containing wastewater and treatment agents, which is beneficial to accelerate the precipitation reaction and improve the wastewater treatment efficiency. At the same time, through the coordination of the reciprocating structure and the knocking structure, scaling of the inner wall of the sedimentation tank is avoided, thereby ensuring the normal use and efficient operation of the sedimentation tank and extending the service life of the equipment.

[0007] Preferably, both ends of the first stirring rod are respectively fixed between the stirring shaft and the second stirring rod, and the interiors of the stirring shaft, the first stirring rod and the second stirring rod are all hollow.

[0008] The beneficial effect of adopting the above-mentioned further scheme is that the interior of the stirring shaft, the first stirring rod and the second stirring rod are arranged in a hollow shape, which greatly reduces the weight of the entire stirring assembly compared to a solid structure while meeting the strength requirements of the equipment. This reduces the inertial load that the driving motor needs to overcome during operation of the equipment, reduces the energy consumption of the motor, and improves energy utilization efficiency.

[0009] Preferably, the outside of the drive motor is welded with a bracket fixed to the upper surface of the horizontal plate. The drive motor is a dual-shaft motor, and its two output shafts are respectively connected to the gear part and the abutment part. The transmission sleeve bearing is installed inside the horizontal plate, and the interior of the transmission sleeve is hollow. The stirring shaft is spline-connected to the transmission sleeve. The gear part consists of two meshing gears, and the two gears are respectively fixed on the outer surface of the transmission sleeve and one of the output shafts of the drive motor.

[0010] The beneficial effect of adopting the above-mentioned further scheme is: by using a dual-axis driving motor, its two output shafts are respectively connected to the gear part and the abutment part. This dual-axis design enables one motor to drive two different transmission systems at the same time, realizing functional integration. While one output shaft drives the stirring shaft to rotate through the gear part to realize the stirring function, the other output shaft drives other components through the abutment part to realize the up and down reciprocating motion of the stirring shaft, which greatly simplifies the structure of the equipment, reduces the number of required motors, reduces the complexity and cost of the equipment, and also improves the compactness and space utilization of the equipment.

[0011] Preferably, the abutment member comprises a circular table fixed to another output shaft of the driving motor, an inclined plate is provided above the circular table, and an electric telescopic rod is hinged between the inclined plate and the circular table; The connecting member consists of a connecting sleeve, a connecting rib and a first abutting roller. The connecting rib is fixed between the connecting sleeve and the first abutting roller. The connecting sleeve is rotatably mounted on the outer surface of the top end of the stirring shaft. The first abutting roller abuts against the outer surface of the inclined disk.

[0012] The beneficial effect of adopting the above-mentioned further scheme is: the abutment is composed of a circular table fixed to another output shaft of the driving motor, an inclined disk arranged above the circular table, and an electric telescopic rod hinged between the two. When the driving motor is running, the circular table rotates accordingly, and the relative position of the inclined disk and the circular table can be flexibly adjusted through the electric telescopic rod. This design enables the change in the position of the inclined disk during rotation to provide a power basis for subsequent transmission, thereby driving the stirring shaft to achieve up and down reciprocating motion, breaking the limitations of traditional stirring methods, enriching the stirring mode, helping to improve the stirring effect of coal-containing wastewater, promoting the full mixing of wastewater and treatment agents, and improving the efficiency and quality of wastewater treatment.

[0013] Preferably, the upper and lower ends of the reciprocating shaft pass through the interior of the stirring shaft, a connecting ring is fixed to the bottom outer surface of the reciprocating shaft, a first return spring is installed between the connecting ring and the inner bottom wall of the stirring shaft, and a second ball is rotatably installed at the bottom end of the reciprocating shaft.

[0014] The beneficial effect of adopting the above-mentioned further scheme is that the upper and lower ends of the reciprocating shaft pass through the interior of the stirring shaft, so that the reciprocating shaft can move up and down relatively freely inside the stirring shaft. When subjected to external force (such as the up and down reciprocating motion of the stirring shaft), the reciprocating shaft can reciprocate axially inside the stirring shaft, providing a basic motion form for realizing subsequent functions such as knocking on the inner wall of the sedimentation tank, enriching the working mode of the equipment, and helping to improve the cleaning effect of the sedimentation tank during the treatment of coal-containing wastewater.

[0015] Preferably, the elastic member includes a slider slidably arranged inside the second stirring rod, a guide groove is provided inside the slider, and a connecting block slides inside the guide groove.

[0016] The beneficial effect of adopting the above-mentioned further scheme is: the slider is slidably arranged inside the second stirring rod, providing a basic sliding guide structure for the elastic part as a whole. At the same time, a guide groove is opened inside the slider, and a connecting block slides inside the guide groove, and a guide rod is fixed between the upper and lower inner walls of the guide groove and passes through the inside of the connecting block. The guiding function can ensure that the connecting block and the parts connected to it move in a straight line strictly along the direction of the guide rod during movement, avoiding deviation or shaking during movement, improving the accuracy and stability of the movement, and ensuring that the equipment can follow the predetermined trajectory when stirring or performing other actions, thereby improving the reliability of the equipment operation.

[0017] Preferably, a guide rod passing through the interior of the connecting block is fixed between the upper and lower inner walls of the guide groove, a second return spring surrounding the outside of the guide rod is fixed between the outer wall of the connecting block and the inner wall of the guide groove, and the end of the first connecting shaft away from the second connecting shaft is fixed to the outer wall of the slider.

[0018] The beneficial effects of adopting the above-mentioned further scheme are: the sliding fit between the guide groove and the connecting block, and the design of the guide rod passing through the connecting block, enable the connecting block to slide relative to the guide groove and the guide rod during movement. Compared with other complex forms of movement, this sliding method can reduce the friction resistance between components, reduce the heat and wear generated by friction, extend the service life of the elastic part and its related components, and also reduce the energy loss during equipment operation and improve energy utilization efficiency.

[0019] Preferably, the hook is composed of a transverse axis and a vertical axis, the transverse axis and the vertical axis are arranged in the X and Y axis directions, and the ends of the transverse axis and the vertical axis close to each other are welded and fixed, and the end of the transverse axis away from the vertical axis is fixed to the outer wall of the slider.

[0020] The beneficial effect of adopting the above-mentioned further scheme is that the hook is composed of a horizontal axis and a vertical axis, which are arranged in the X and Y axis directions and are welded and fixed close to one end. This simple structural form is easy to manufacture and install, reducing production costs and assembly difficulty. At the same time, welding fixation ensures the connection strength and stability between the horizontal axis and the vertical axis, so that the hook can reliably withstand various forces and torques during the working process, providing a solid foundation for subsequent cooperation with the slider and the slide seat.

[0021] Preferably, a hook groove adapted to the vertical shaft is opened inside the sliding seat, an oblique guide seat is fixed on the inner top wall and the inner bottom wall of the second stirring rod, and a second abutting roller rollingly matched with the oblique guide seat is fixed on the outer surface of the vertical shaft.

[0022] The beneficial effect of adopting the above-mentioned further scheme is that the oblique design of the oblique guide seat enables the second abutment roller to drive the vertical axis to produce a specific displacement in the hook groove during the rolling process, thereby realizing the displacement control of the slide by the hook. This design can meet the special requirements of the equipment for the slide position under different working conditions.

[0023] Preferably, the number of the connecting blocks and the hooks are both two, and the two hooks are distributed up and down and are engaged with the oblique guide seat through the second abutting roller to achieve displacement of the hooks relative to the slide seat; A connecting plate is fixed on the inner wall of the second stirring rod, a guide groove adapted to the connecting plate is provided inside the sliding seat, and a third reset spring is fixed between the inner wall of the guide groove and the connecting plate.

[0024] The beneficial effect of adopting the above-mentioned further scheme is that when the slide is displaced by external force, the third return spring will be stretched or compressed to store elastic potential energy. When the external force disappears, the third return spring will release the stored elastic potential energy, pushing the slide along the guide groove back to its initial position, thereby realizing the automatic reset function of the slide. This automatic reset function enables the equipment to quickly return to normal working state after being disturbed, which not only ensures the continuity and stability of the equipment operation, reduces the frequency of manual intervention and equipment adjustment, improves the degree of automation and work efficiency of the equipment, but also can use the knocking block to perform the knocking function.

[0025] The present invention has at least the following beneficial effects: 1. When the stirring shaft of the present invention reciprocates up and down, the reciprocating shaft inside it contacts the bottom wall of the sedimentation tank and utilizes the deformation of the first return spring to achieve up and down reciprocating motion. During the up and down reciprocating motion of the reciprocating shaft, the reciprocating motion of the reciprocating shaft is converted into the reciprocating motion of the first connecting shaft through the abutment and cooperation between the first ball and the wave groove. This conversion method has a simple structure and cleverly utilizes the rolling cooperation in the mechanical structure and the elastic deformation of the spring to convert the simple up and down motion into a more complex reciprocating motion, providing a power source for the subsequent movement of the knocking structure. In addition, the entire conversion process is stable and efficient, reducing energy loss and improving the reliability of equipment operation.

[0026] 2. An output shaft of the driving motor of the present invention drives the transmission sleeve to rotate through a gear part, and the stirring shaft is spline-connected to the transmission sleeve. This transmission method is stable and reliable, and can ensure the stable rotation of the stirring shaft, thereby driving the first stirring rod and the second stirring rod to fully stir the coal-containing wastewater in the sedimentation tank. Effective stirring can fully mix the wastewater and the treatment agent, accelerate the precipitation reaction, improve the wastewater treatment efficiency, shorten the treatment time, reduce the treatment cost, and improve the working efficiency of the entire coal-containing wastewater treatment equipment, thereby meeting the requirements for wastewater treatment speed and quality in actual production.

[0027] 3. In the present invention, another output shaft of the driving motor drives the circular table to rotate. The electric telescopic rod can adjust the relative position of the inclined disk and the circular table, and can flexibly control the rolling trajectory of the first abutting roller on the outer surface of the inclined disk, thereby driving the stirring shaft to reciprocate up and down in the transmission sleeve. The up and down reciprocating motion of the stirring shaft breaks the traditional single stirring mode, so that the wastewater forms a more complex water flow movement in the sedimentation tank, further promotes the mixing of wastewater and chemicals, enhances the sedimentation effect, improves the sedimentation efficiency, and helps to more thoroughly remove impurities and pollutants in the wastewater.

[0028] 4. In the reciprocating motion of the first connecting shaft of the present invention, the elastic member and the hook member are driven to approach the slide seat. When the hook member is displaced, the second abutting roller thereon rolls along the inclined surface of the oblique guide seat, and the inclined surface of the oblique guide seat is used to drive the hook member to approach the slide seat and be hooked with the hook groove through the vertical shaft. When the hook member returns to its original position, the slide seat is driven to extend deep into the second stirring rod. When the hook member moves back, as the second abutting roller is no longer squeezed by the oblique guide seat, the hook member slowly moves away from the slide seat. At this time, the hook member is disconnected from the slide seat and the deformation of the third return spring is used to drive the slide seat to reset. The slide seat is reset to knock the lumps on the inner wall of the sedimentation tank through the knocking block. This complex motion coordination design can effectively realize the knocking function, avoid scaling on the inner wall of the sedimentation tank, ensure the normal operation and service life of the sedimentation tank, reduce the workload and difficulty of manual cleaning of the inner wall of the sedimentation tank, and reduce the equipment maintenance cost.

[0031] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0032] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0033] like Figures 1-12 As shown, the efficient treatment device for coal-containing wastewater provided in this embodiment includes a sedimentation tank 1 and a horizontal plate 11 fixed to the inside of the sedimentation tank 1, and a stirring assembly 2 and a driving structure 3 are provided on the sedimentation tank 1; wherein, the stirring assembly 2 is composed of a stirring shaft 21, a first stirring rod 22 and a second stirring rod 23; specifically, the two ends of the first stirring rod 22 are respectively fixed between the stirring shaft 21 and the second stirring rod 23, and the interiors of the stirring shaft 21, the first stirring rod 22 and the second stirring rod 23 are all hollow. By setting the interiors of the stirring shaft 21, the first stirring rod 22 and the second stirring rod 23 to be hollow, the weight of the entire stirring assembly 2 is greatly reduced compared to a solid structure while meeting the strength requirements of the equipment. This reduces the inertial load that the driving structure 3 needs to overcome during operation of the equipment, reduces the energy consumption of the motor, and improves energy utilization efficiency.

[0034] The driving structure 3 is composed of a driving motor 31, a transmission sleeve 32, a gear part 33 and an abutment, and a connecting part 37 is provided between the stirring shaft 21 and the abutment; wherein, the outside of the driving motor 31 is welded with a bracket fixed to the upper surface of the horizontal plate 11, the driving motor 31 is a dual-axis motor, and its two output shafts are respectively connected to the gear part 33 and the abutment, the transmission sleeve 32 bearing is installed inside the horizontal plate 11, and the interior of the transmission sleeve 32 is hollow, the stirring shaft 21 is splined to the transmission sleeve 32, and the gear part 33 is composed of two meshing gears, and the two gears are respectively fixed to the outer surface of the transmission sleeve 32 and one of the output shafts of the driving motor 31. It should be noted that, because the driving motor 31 is a dual-axis motor, its two output shafts are respectively connected to the gear part 33 and the abutment, this dual-axis design enables one motor to drive two different transmission systems at the same time, thereby realizing functional integration. While one output shaft drives the stirring shaft 21 to rotate through the gear part 33 to realize the stirring function, the other output shaft drives other components such as the table 34 through the abutment part to realize the up and down reciprocating motion of the stirring shaft 21, which greatly simplifies the structure of the equipment, reduces the number of required motors, reduces the complexity and cost of the equipment, and also improves the compactness and space utilization of the equipment.

[0035] To achieve the lifting and lowering of the agitator shaft 21, the abutment includes a circular platform 34 fixed to the other output shaft of the drive motor 31. A beveled disc 35 is installed above the circular platform 34, and an electric telescopic rod 36 is hinged between the beveled disc 35 and the circular platform 34. The connecting member 37 consists of a connecting sleeve 371, a connecting rib 372, and a first abutting roller 373. The connecting rib 372 is fixed between the connecting sleeve 371 and the first abutting roller 373. The connecting sleeve 371 is rotatably mounted on the outer surface of the top end of the agitator shaft 21, and the first abutting roller 373 abuts the outer surface of the beveled disc 35. The abutment comprises the circular platform 34 fixed to the other output shaft of the drive motor 31, the beveled disc 35 installed above the circular platform 34, and the electric telescopic rod 36 hinged between the two. When the drive motor 31 is running, the table 34 rotates accordingly. The relative position of the inclined disk 35 and the table 34 can be flexibly adjusted through the electric telescopic rod 36. This design allows the inclined disk 35 to change its position during rotation, which can provide a power basis for subsequent transmission, thereby driving the stirring shaft 21 to achieve up and down reciprocating motion, breaking the limitations of traditional stirring methods, enriching the stirring mode, helping to improve the stirring effect of coal-containing wastewater, promoting the full mixing of wastewater and treatment agents, and improving the efficiency and quality of wastewater treatment.

[0036] In this embodiment, a reciprocating structure 4 extending outside the stirring shaft 21 is provided inside the stirring shaft 21, and a knocking structure 5 used in conjunction with the reciprocating structure 4 is provided on the first stirring rod 22 and the second stirring rod 23; the stirring is made more sufficient by combining stirring with up and down reciprocating motion, thereby improving the mixing effect of the coal-containing wastewater and the treatment agent, which is beneficial to accelerate the precipitation reaction and improve the wastewater treatment efficiency. At the same time, the reciprocating structure 4 cooperates with the knocking structure 5 to avoid scaling on the inner wall of the sedimentation tank 1, thereby ensuring the normal use and efficient operation of the sedimentation tank 1 and extending the service life of the equipment.

[0037] The reciprocating structure 4 includes a reciprocating shaft 41 disposed inside the stirring shaft 21. The outside of the reciprocating shaft 41 is provided with a connecting structure 42 extending to the inside of the first stirring rod 22. The connecting structure 42 includes a first connecting shaft 421 and a second connecting shaft 422. A shaft 423 is detachably installed inside the second connecting shaft 422. A first ball 424 is rotatably installed at one end of the shaft 423. A wave groove 43 is provided inside the stirring shaft 21 to roll with the first ball 424. The upper and lower ends of the reciprocating shaft 41 both pass through the inside of the stirring shaft 21. The stirring shaft 21 plays a good guiding role for the reciprocating shaft 41, limiting the radial shaking of the reciprocating shaft 41 so that it can only perform stable reciprocating motion along the axial direction. This stable motion trajectory ensures that the reciprocating shaft 41 will not deviate or jam during operation, thereby improving the reliability and stability of the equipment operation, reducing the risk of mechanical failure caused by unstable motion, and extending the service life of the equipment. A connecting ring 44 is fixed to the outer surface of the bottom side of the reciprocating shaft 41, and a first return spring 45 is installed between the connecting ring 44 and the inner bottom wall of the stirring shaft 21. A second ball is rotatably installed on the bottom end of the reciprocating shaft 41. Specifically, the upper and lower ends of the reciprocating shaft 41 pass through the interior of the stirring shaft 21, so that the reciprocating shaft 41 can move up and down relatively freely inside the stirring shaft 21. When driven by an external force such as the up and down reciprocating motion of the stirring shaft 21, the reciprocating shaft 41 can reciprocate axially inside the stirring shaft 21, providing a basic form of motion for achieving subsequent functions such as knocking on the inner wall of the sedimentation tank 1, enriching the working mode of the equipment, and helping to improve the cleaning effect of the sedimentation tank 1 during the treatment of coal-containing wastewater. A sealing gasket is provided at the bottom connection between the stirring shaft 21 and the reciprocating shaft 41.

[0038] It should be noted that by adjusting the angle of the abutment, not only the reciprocating effect of the stirring shaft 21 can be adjusted, but also the driving of the reciprocating structure 4 can be achieved. At the same time, by controlling the driving speed of the driving structure 3, the reciprocating structure 4 is adapted thereto, thereby driving the knocking speed of the knocking structure 5. This precise speed control can flexibly adjust the knocking force and frequency of the knocking structure 5 according to the severity of the scaling on the inner wall of the sedimentation tank 1. When the scaling is thicker and harder, the driving speed of the driving structure 3 is increased, the knocking speed of the knocking structure 5 is accelerated, the knocking force is enhanced, and the scaling is effectively removed; when the scaling is thinner and softer, the driving speed of the driving structure 3 is reduced, the knocking speed of the knocking structure 5 is slowed down, and excessive damage to the inner wall of the sedimentation tank 1 is avoided, thereby achieving precise control of the cleaning force. The number of the first stirring rod 22 and the second stirring rod 23 is not limited and can be used according to demand. When the number of the first stirring rod 22 and the second stirring rod 23 is large, the length of the wave groove 43 is extended accordingly.

[0039] In addition, when the stirring shaft 21 is raised and lowered, the knocking structure 5 can knock on different positions of the sedimentation tank 1, further improving the cleaning effect; when the reciprocating shaft 41 abuts against the inner bottom wall of the sedimentation tank 1, the reciprocating shaft 41 can also produce a knocking effect, thereby knocking on the bottom side of the sedimentation tank 1, and at the same time, the first return spring 45 is used to play a buffering and shock-absorbing role during the movement of the reciprocating shaft 41.

[0040] The knocking structure 5 includes a slide 51 and an elastic member 52 arranged inside the second stirring rod 23, a hook 53 is provided between the slide 51 and the elastic member 52, one end of the first connecting shaft 421 is connected to the elastic member 52, and a knocking block 57 is fixed to the side of the slide 51 away from the elastic member 52. The knocking block 57 extends to the outside of the second stirring rod 23, and a sealing gasket is provided at the connection between the second stirring rod 23 and the knocking block 57 to prevent impurities from entering the interior of the second stirring rod 23. The elastic member 52 includes a slider 521 slidably arranged inside the second stirring rod 23, a guide groove 523 is provided inside the slider 521, and a connecting block 522 is slidably provided inside the guide groove 523. The slider 521 is slidably arranged inside the second stirring rod 23, providing a basic sliding guide structure for the elastic member 52 as a whole. At the same time, a guide groove 523 is provided inside the slider 521, and a connecting block 522 slides inside the guide groove 523, and a guide rod 524 is fixed between the upper and lower inner walls of the guide groove 523 and passes through the inside of the connecting block 522. The guiding function can ensure that the connecting block 522 and the components connected thereto strictly move in a straight line along the direction of the guide rod 524 during movement, avoiding deviation or shaking during movement, improving the accuracy and stability of movement, and ensuring that the equipment can follow a predetermined trajectory when stirring or performing other actions, thereby improving the reliability of equipment operation.

[0041] In this embodiment, a guide rod 524 is fixed between the upper and lower inner walls of the guide groove 523 and extends through the interior of the connecting block 522. A second return spring 525 is fixed between the outer wall of the connecting block 522 and the inner wall of the guide groove 523, surrounding the exterior of the guide rod 524. The end of the first connecting shaft 421 away from the second connecting shaft 422 is fixed to the outer wall of the slider 521. The sliding fit between the guide groove 523 and the connecting block 522, and the design in which the guide rod 524 extends through the connecting block 522, allow the connecting block 522 to slide relative to the guide groove 523 and the guide rod 524 during movement. Compared to other complex motion forms, this sliding method can reduce frictional resistance between components, reduce heat and wear generated by friction, extend the service life of the elastic member 52 and its related components, and also reduce energy loss during equipment operation, thereby improving energy utilization efficiency.

[0042] Specifically, hook member 53 comprises a transverse axis 531 and a vertical axis 532, which are arranged in the X- and Y-axis directions. The ends of transverse axis 531 and vertical axis 532 that are adjacent to each other are welded and fixed, while the end of transverse axis 531 that is distal from vertical axis 532 is fixed to the outer wall of slider 521. Hook member 53 comprises a transverse axis 531 and a vertical axis 532 that are arranged in the X- and Y-axis directions and welded and fixed at their adjacent ends. This simple structure facilitates manufacturing and installation, reducing production costs and assembly difficulty. Furthermore, the welding ensures the strength and stability of the connection between transverse axis 531 and vertical axis 532, enabling hook member 53 to reliably withstand various forces and torques during operation, providing a solid foundation for subsequent coordination with slider 521 and slide seat 51.

[0043] To achieve movement of the slide 51, a hook groove 533 is provided within the slide 51, adapted to mate with the vertical shaft 532. An oblique guide seat 54 is fixed to the inner top and bottom walls of the second stirring rod 23. A second abutment roller 534 is fixed to the outer surface of the vertical shaft 532, which rolls in engagement with the oblique guide seat 54. It should be noted that the oblique design of the oblique guide seat 54 enables the second abutment roller 534 to drive the vertical shaft 532 to produce a specific displacement within the hook groove 533 during rolling, thereby enabling the hook 53 to control the displacement of the slide 51. This design can meet the specific requirements of the device for the position of the slide 51 under different operating conditions. There are two connecting blocks 522 and two hooks 53, each distributed vertically. These two hooks 53 are engaged with the oblique guide seat 54 through the second abutment roller 534, enabling the hook 53 to move the slide 51. The two hooks 53 can simultaneously apply a force to the slide 51 through the abutment cooperation with the second abutment roller 534 and the oblique guide seat 54. Compared with a single hook 53, the force is greater and more evenly distributed, thereby enhancing the driving ability of the hook 53 on the slide 51, so that the slide 51 can be displaced more stably and reliably, thereby improving the stability and reliability of the equipment operation.

[0044] In this embodiment, a connecting plate 56 is fixed to the inner wall of the second stirring rod 23, and a guide groove adapted for the connecting plate 56 is provided within the interior of the slide 51. The combination of the connecting plate 56 and the guide groove provides guidance for the movement of the slide 51, limiting horizontal sway of the slide 51 and restricting linear motion of the slide 51 to the direction of the guide groove. This ensures the stability and accuracy of the slide 51's movement and reduces the risk of equipment failure due to unstable movement. A third return spring 55 is fixed between the inner wall of the guide groove and the connecting plate 56. When the slide 51 is displaced by an external force, the third return spring 55 is stretched or compressed, storing elastic potential energy. When the external force disappears, the third return spring 55 releases the stored elastic potential energy, pushing the slide 51 back to its initial position along the guide groove, thus realizing the automatic return function of the slide 51. This automatic return function enables the device to quickly return to normal working state after being disturbed, which not only ensures the continuity and stability of the device operation, reduces the frequency of manual intervention and device adjustment, improves the degree of automation and working efficiency of the device, but also enables the use of the knocking block 57 to perform the knocking function. A third ball can also be installed at the end of the knocking block 57 to cooperate with the stirring of the stirring shaft 21.

[0045] like Figures 1-12 As shown, the principle of the efficient treatment device for coal-containing wastewater provided in this embodiment is as follows: The drive motor 31 is started. As a dual-shaft motor, one of its output shafts drives the transmission sleeve 32 to rotate through the gear member 33. Since the stirring shaft 21 is spline-connected with the transmission sleeve 32, the stirring shaft 21 is driven to rotate. The stirring shaft 21 drives the first stirring rod 22 and the second stirring rod 23 to stir the coal-containing wastewater in the sedimentation tank 1. Another output shaft of the drive motor 31 drives the circular table 34 to rotate. The electric telescopic rod 36 can adjust the relative position of the inclined plate 35 and the circular table 34. During the rotation of the circular table 34, the electric telescopic rod 36 is adjusted to change the relative position of the inclined plate 35 and the circular table 34, thereby causing the first abutting roller 373 to roll on the outer surface of the inclined plate 35, thereby driving the stirring shaft 21 to reciprocate up and down in the transmission sleeve 32 through the connecting member 37. When the stirring shaft 21 reciprocates up and down, the reciprocating shaft 41 inside it contacts the inner bottom wall of the sedimentation tank 1 and uses the deformation of the first return spring 45 to achieve up and down reciprocating motion. During the up and down reciprocating motion of the reciprocating shaft 41, the first ball 424 abuts against the wave groove 43, converting the reciprocating motion of the reciprocating shaft 41 into the reciprocating motion of the first connecting shaft 421. During the reciprocating motion of the first connecting shaft 421, the elastic member 52 and the hook member 53 are driven closer to the slide seat 51. When the hook 53 is displaced, the second abutting roller 534 thereon rolls along the inclined surface of the oblique guide seat 54. As the second abutting roller 534 rolls and displaces, the oblique surface of the oblique guide seat 54 is used to drive the hook 53 toward the slide 51 and, through the hook connection between the vertical axis 532 and the hook groove 533, the slide 51 is driven to extend deep into the second stirring rod 23 when the hook 53 returns to its original position. When the hook 53 moves back, as the second abutting roller 534 is no longer squeezed by the oblique guide seat 54, the hook 53 slowly moves away from the slide 51. At this time, the hook 53 is disconnected from the slide 51 and the deformation of the third return spring 55 is used to drive the slide 51 to return to its original position. The slide 51 is reset to knock the lumps on the inner wall of the sedimentation tank 1 through the knocking block 57 to avoid scaling on the inner wall of the sedimentation tank 1.

[0046] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term and should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.
