Description

TECHNICAL FIELD

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

[0002] Coal washing wastewater contains a large amount of suspended solids, coal slime and silt, so it is also called coal slime water. The concentration of suspended solids in untreated coal slime water can reach more than 5000 mg / L. Due to the hydrophobicity of coal, some small coal dust in coal washing wastewater is particularly stable in water, and some ultra-fine coal dust is suspended in water and will not naturally settle for several months. Coal washing wastewater is a weakly alkaline colloidal system, mainly characterized by strong negative charge on the surface of particles, high concentration and CODcr concentration; high content of fine particles; high viscosity; large sludge specific resistance, poor filtration performance. The coal-containing wastewater generated by the existing coal conveying system is collected in a coal-containing wastewater sedimentation tank and recycled to a coal-water clean water tank after treatment;

[0003] CN114632374B discloses "a high-efficiency device for treating coal-containing wastewater, which relates to the technical field of coal-containing wastewater treatment, comprising: a sedimentation tank, a fixed frame is fixedly connected to the top of the sedimentation tank, a driving mechanism is installed at the top of the fixed frame; a reciprocating mechanism; a stirring mechanism for stirring operation; a rotating mechanism installed at the inner side wall bottom of the sedimentation tank, the rotating mechanism drives the stirring mechanism to rotate; when the flow meter detects that the amount of coal-containing wastewater in the sedimentation tank reaches the working requirement of the driving motor, the driving mechanism starts to work to a certain extent. Stirring, the work of the driving mechanism will drive the stirring mechanism to move upward through the reciprocating mechanism, so that the stirring mechanism rotates under the action of the rotating mechanism and returns to the bottom state, preventing sedimentation at the bottom of the sedimentation tank and preventing the adhesion of coal slime on the side wall of the sedimentation tank affecting subsequent use and wastewater treatment";

[0004] However, the above-mentioned patent still has the following defects: the bidirectional screw groove is easy to be blocked, the coal slime particles are easy to enter the bidirectional screw groove during use, which hinders the sliding of the connecting rod and reduces the stirring efficiency, and the application only relies on the rotation and reciprocating scraping of the stirring blade, which cannot effectively destroy the adhesion between the coal slime and the pool wall. High-viscosity coal slime is easy to form a stubborn adherent layer on the side wall, which gradually thickens and hardens, and further has the defect of low wall cleaning efficiency.

[0026] The beneficial effect of the above further scheme is that the sliding cooperation of the guide groove and the connecting block, and the design of the guide rod penetrating the connecting block enable the connecting block to relatively slide with the guide groove and the guide rod during movement. Compared with other complex movement forms, this sliding mode can reduce the frictional resistance between components, reduce the heat and wear caused by friction, prolong the service life of the elastic member and related components, reduce energy loss during equipment operation, and improve energy utilization efficiency.

[0034] The present application has at least the following beneficial effects:

[0035] 1. When the stirring shaft of the present invention reciprocates up and down, its internal reciprocating shaft contacts the bottom wall of the sedimentation tank and uses the deformation of the first return spring to achieve the 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 abutting cooperation of the first ball and the wave groove. This conversion method has a simple structure and cleverly utilizes the rolling cooperation and elastic deformation of the spring in the mechanical structure to transform the simple up and down motion into a more complex reciprocating motion, providing a power source for the subsequent striking structure. Moreover, the entire conversion process is stable and efficient, reduces energy loss, and improves the reliability of equipment operation.

[0036] 2. In this invention, one output shaft of the drive motor drives the transmission sleeve to rotate via gear components. The stirring shaft is splinedly connected to the transmission sleeve. This transmission method is stable and reliable, ensuring stable rotation of the stirring shaft. This, in turn, drives the first and second stirring rods to fully stir the coal-containing wastewater in the sedimentation tank. Effective stirring allows the wastewater and treatment agents to mix thoroughly, accelerating the sedimentation reaction, improving wastewater treatment efficiency, shortening treatment time, reducing treatment costs, and enhancing the overall working efficiency of the coal-containing wastewater treatment equipment. This meets the requirements for wastewater treatment speed and quality in actual production.

[0037] 3. The other output shaft of the drive motor of this invention drives the truncated cone to rotate. The electric telescopic rod can adjust the relative position of the inclined plate and the truncated cone, and can flexibly control the rolling trajectory of the first abutting roller on the outer surface of the inclined plate, thereby driving the stirring shaft to move up and down in the transmission sleeve. The up and down reciprocating motion of the stirring shaft breaks the traditional single stirring method, so that the wastewater forms a more complex water flow in the sedimentation tank, further promoting the mixing of wastewater and reagents, enhancing the sedimentation effect, improving the sedimentation efficiency, and helping to remove impurities and pollutants in the wastewater more thoroughly.

[0038] 4. During the reciprocating motion of the first connecting shaft of this invention, the elastic element and the hook element move closer to the slide. When the hook element is displaced, the second abutting roller on it rolls along the inclined surface of the inclined guide seat. The inclined surface of the inclined guide seat drives the hook element to move closer to the slide and hooks it with the hook groove through the vertical shaft. When the hook element returns to its original position, it drives the slide to extend deeper into the interior of the second stirring rod. When the hook element returns, as the second abutting roller is no longer squeezed by the inclined guide seat, the hook element slowly moves away from the slide. At this time, the hook element disengages from the slide. The deformation of the third return spring drives the slide to return to its original position. The return of the slide to its original position knocks the clumps on the inner wall of the sedimentation tank through the knocking block. This complex motion coordination design can effectively realize the knocking function, avoid scale buildup 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 manually cleaning the inner wall of the sedimentation tank, and reduce equipment maintenance costs.

DETAILED DESCRIPTION

[0053] The technical solutions of the present application will be further described in detail below in conjunction with specific embodiments.

[0054] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are only used to explain the present application and cannot be understood as a limitation of the present application.

[0055] As Figures 1-12 shown, the efficient coal-containing wastewater treatment device provided by the embodiment includes a sedimentation tank 1 and a horizontal plate 11 fixed inside the sedimentation tank 1, and a stirring assembly 2 and a driving structure 3 are arranged 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 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 arranging the interiors of the stirring shaft 21, the first stirring rod 22 and the second stirring rod 23 in a hollow shape, compared with a solid structure, the weight of the entire stirring assembly 2 is greatly reduced under the premise of meeting the strength requirement of the equipment. This makes the inertia load required to be overcome by the driving structure 3 reduced during the operation of the equipment, reduces the energy consumption of the motor, and improves the energy utilization efficiency.

[0056] The driving structure 3 is composed of a driving motor 31, a transmission sleeve 32, a gear part 33 and an abutting part, and a connecting part 37 is arranged between the stirring shaft 21 and the abutting part; wherein the driving motor 31 is welded with a support fixed on the upper surface of the horizontal plate 11, the driving motor 31 is a double-shaft motor, and the two output shafts thereof are connected with the gear part 33 and the abutting part respectively, the transmission sleeve 32 is bearing-mounted inside the horizontal plate 11, and the inside of the transmission sleeve 32 is hollow, the stirring shaft 21 is splined with the transmission sleeve 32, and the gear part 33 is composed of two meshing gears, and the two gears are fixed on the outer surface of the transmission sleeve 32 and one of the output shafts of the driving motor 31 respectively. It should be noted that the driving motor 31 is a double-shaft motor, and the two output shafts thereof are connected with the gear part 33 and the abutting part respectively, and such a double-shaft design enables one motor to drive two different transmission systems at the same time, realizing the integration of functions. 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 circular table 34 to realize the up-and-down reciprocating motion of the stirring shaft 21, greatly simplifying the structure of the equipment, reducing the number of motors required, reducing the complexity and cost of the equipment, and improving the compactness and space utilization of the equipment.

[0057] To realize the lifting of the stirring shaft 21, the abutting part includes a circular table 34 fixed on the other output shaft of the driving motor 31, an oblique disc 35 is arranged above the circular table 34, and an electric telescopic rod 36 is hinged between the oblique disc 35 and the circular table 34; the connecting part 37 is composed 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 stirring shaft 21, and the first abutting roller 373 abuts against the outer surface of the oblique disc 35. The abutting part is composed of the circular table 34 fixed on the other output shaft of the driving motor 31, the oblique disc 35 arranged above the circular table 34 and the electric telescopic rod 36 hinged between the oblique disc 35 and the circular table 34. When the driving motor 31 operates, the circular table 34 rotates, and the relative position of the oblique disc 35 and the circular table 34 can be flexibly adjusted through the electric telescopic rod 36. Such a design enables the position of the oblique disc 35 to change during rotation, which provides a power basis for subsequent transmission, thereby driving the stirring shaft 21 to realize the up-and-down reciprocating motion, breaking the limitations of the traditional stirring mode, enriching the stirring mode, helping to improve the stirring effect of the coal-containing wastewater, promoting the full mixing of the wastewater and the treatment agent, and improving the wastewater treatment efficiency and quality.

[0058] In the embodiment, the reciprocating structure 4 is arranged inside the stirring shaft 21 and extends out of the stirring shaft 21, the knocking structure 5 is arranged on the first stirring rod 22 and the second stirring rod 23 and cooperates with the reciprocating structure 4, the stirring is combined with the up-down reciprocating movement to make the stirring more sufficient, the mixing effect of the coal-containing wastewater and the treatment agent is improved, the precipitation reaction is accelerated, the wastewater treatment efficiency is improved, the inner wall of the sedimentation tank 1 is prevented from scaling by the cooperation of the reciprocating structure 4 and the knocking structure 5, the normal use and efficient operation of the sedimentation tank 1 are ensured, and the service life of the equipment is prolonged.

[0059] The reciprocating structure 4 comprises a reciprocating shaft 41 arranged inside the stirring shaft 21, the reciprocating shaft 41 is provided with a connecting structure 42 extending into the first stirring rod 22, the connecting structure 42 comprises a first connecting shaft 421 and a second connecting shaft 422, the second connecting shaft 422 is detachably provided with a shaft rod 423 inside, one end of the shaft rod 423 is rotatably provided with a first rolling ball 424, and the inside of the stirring shaft 21 is provided with a wave groove 43 in rolling cooperation with the first rolling ball 424. The reciprocating shaft 41 penetrates the inside of the stirring shaft 21 at both ends, the stirring shaft 21 plays a good guiding role on the reciprocating shaft 41, limits the radial shaking of the reciprocating shaft 41, and makes the reciprocating shaft 41 only perform stable reciprocating movement in the axial direction. The stable movement track ensures that the reciprocating shaft 41 will not deviate or jam during operation, improves the reliability and stability of the equipment operation, reduces the risk of mechanical failure caused by unstable movement, and prolongs the service life of the equipment. The connecting ring 44 is fixed to the outer surface of the bottom side of the reciprocating shaft 41, the first return spring 45 is arranged between the connecting ring 44 and the inner bottom wall of the stirring shaft 21, and the second rolling ball is rotatably arranged at the bottom end of the reciprocating shaft 41. Specifically, the reciprocating shaft 41 penetrates the inside of the stirring shaft 21 at both ends, so that the reciprocating shaft 41 can move up and down relatively freely inside the stirring shaft 21. When subjected to external forces such as up-down reciprocating movement of the stirring shaft 21, the reciprocating shaft 41 can reciprocate in the axial direction inside the stirring shaft 21, which provides a basic movement form for subsequent knocking of the inner wall of the sedimentation tank 1, enriches the working mode of the equipment, and helps to improve the cleaning effect of the sedimentation tank 1 in the coal-containing wastewater treatment process. The sealing gasket is arranged at the connection between the stirring shaft 21 and the bottom of the reciprocating shaft 41.

[0060] It should be noted that by adjusting the angle of the abutting member, not only can the reciprocating effect of the stirring shaft 21 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 can be adapted, and the knocking speed of the knocking structure 5 can be driven. 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 thick and hard, the driving speed of the driving structure 3 is increased, the knocking speed of the knocking structure 5 is increased, and the knocking force is increased, so as to effectively remove the scaling. When the scaling is thin and soft, the driving speed of the driving structure 3 is reduced, the knocking speed of the knocking structure 5 is reduced, and the inner wall of the sedimentation tank 1 is not damaged, so as to achieve 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 the needs. 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 correspondingly lengthened.

[0061] In addition, when the stirring shaft 21 is lifted, the knocking structure 5 can knock 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, achieving knocking on the bottom side of the sedimentation tank 1. At the same time, the first return spring 45 plays a role in buffering and damping during the movement of the reciprocating shaft 41.

[0062] The knocking structure 5 includes a sliding seat 51 and an elastic member 52 arranged inside the second stirring rod 23, a hook 53 is arranged between the sliding seat 51 and the elastic member 52, one end of the first connecting shaft 421 is connected with the elastic member 52, and a knocking block 57 is fixed to the side of the sliding seat 51 away from the elastic member 52. The knocking block 57 extends to the outside of the second stirring rod 23, and a sealing washer is arranged at the connection between the second stirring rod 23 and the knocking block 57 to prevent impurities from entering the inside of the second stirring rod 23. The elastic member 52 includes a sliding block 521 slidingly arranged inside the second stirring rod 23, a guide groove 523 is arranged in the inside of the sliding block 521, and a connecting block 522 is slidingly arranged in the inside of the guide groove 523. The sliding block 521 slidingly arranged inside the second stirring rod 23 provides a basic sliding guide structure for the whole elastic member 52. At the same time, the guide groove 523 is arranged in the inside of the sliding block 521, the connecting block 522 is slidingly arranged in the inside of the guide groove 523, and a guide rod 524 penetrating through the inside of the connecting block 522 is fixed between the upper and lower inner walls of the guide groove 523. The guide function can ensure that the connecting block 522 and the components connected therewith move strictly along the direction of the guide rod 524 during movement, avoiding deviation or shaking during movement, improving the accuracy and stability of movement, ensuring that the equipment can move according to the predetermined trajectory during stirring or other actions, and improving the reliability of equipment operation.

[0063] In this embodiment, the guide groove 523 is fixed with a guide rod 524 penetrating the inside of the connecting block 522, the outer wall of the connecting block 522 is fixed with a second reset spring 525 surrounding the outside of the guide rod 524 between the inner wall of the guide groove 523, and the outer wall of the sliding block 521 is fixed with the first connecting shaft 421 away from the second connecting shaft 422. The sliding cooperation of the guide groove 523 and the connecting block 522, and the design of the guide rod 524 penetrating the connecting block 522, make the connecting block 522 form relative sliding between the guide groove 523 and the guide rod 524 during movement. This sliding mode can reduce the frictional resistance between components compared to other complex movement forms, reduce heat and wear generated by friction, prolong the service life of the elastic member 52 and its related components, reduce energy loss during equipment operation, and improve energy utilization efficiency.

[0064] Specifically, the hook piece 53 is composed of a horizontal shaft 531 and a vertical shaft 532, which are arranged in X and Y axis directions and are fixed by welding at one end close to each other, and the outer wall of the sliding block 521 is fixed with the end of the horizontal shaft 531 away from the vertical shaft 532. The hook piece 53 is composed of a horizontal shaft 531 and a vertical shaft 532, which are arranged in X and Y axis directions and are fixed by welding at one end close to each other, which is a simple structure form convenient for manufacturing and installation, reduces production cost and assembly difficulty. At the same time, the welding fixation guarantees the connection strength and stability between the horizontal shaft 531 and the vertical shaft 532, so that the hook piece 53 can reliably withstand various forces and torques in the working process, providing a solid foundation for subsequent cooperation with the sliding block 521 and the sliding seat 51.

[0065] To realize the movement of the sliding seat 51, a hook groove 533 matched with the vertical shaft 532 is arranged in the sliding seat 51, and the inner top wall and the inner bottom wall of the second stirring rod 23 are both fixed with a slant guide seat 54, and the outer surface of the vertical shaft 532 is fixed with a second abutting roller 534 which is in rolling contact with the slant guide seat 54. It should be noted that the slant design of the slant guide seat 54 enables the second abutting roller 534 to drive the vertical shaft 532 to produce a specific displacement in the hook groove 533 during rolling, thereby realizing the displacement control of the sliding seat 51 by the hook piece 53. This design can meet the special requirements of the equipment on the position of the sliding seat 51 in different working states. The number of the connecting blocks 522 and the hook pieces 53 is both two, and the two hook pieces 53 are distributed above and below and are in abutting contact with the slant guide seat 54 through the second abutting roller 534, thereby realizing the displacement of the sliding seat 51 by the hook piece 53. The abutting contact of the two hook pieces 53 with the slant guide seat 54 through the second abutting roller 534 can simultaneously exert a force on the sliding seat 51, and compared with a single hook piece 53, the force is larger and more evenly distributed, thereby enhancing the driving capacity of the hook piece 53 on the sliding seat 51, making the sliding seat 51 more stably and reliably displace, and improving the stability and reliability of the equipment operation.

[0066] In the embodiment, the inner wall of the second stirring rod 23 is fixed with a connecting plate 56, and the inside of the sliding seat 51 is arranged with a guide groove matched with the connecting plate 56. The cooperation of the connecting plate 56 and the guide groove provides a guiding effect for the movement of the sliding seat 51, limits the shaking of the sliding seat 51 in the horizontal direction, and makes the sliding seat 51 only move linearly along the direction of the guide groove, thereby ensuring the stability and accuracy of the movement of the sliding seat 51 and reducing the risk of equipment failure caused by unstable movement. A third return spring 55 is fixed between the inner wall of the guide groove and the connecting plate 56. When the sliding seat 51 is displaced by an external force, the third return spring 55 will be stretched or compressed to store elastic potential energy. When the external force disappears, the third return spring 55 will release the stored elastic potential energy to push the sliding seat 51 back to the initial position along the guide groove, thereby realizing the automatic reset function of the sliding seat 51. This automatic reset function enables the equipment to quickly recover to the normal working state after being disturbed, thereby not only ensuring the continuity and stability of the equipment operation, reducing the frequency of manual intervention and equipment adjustment, improving the automation degree and working efficiency of the equipment, but also enabling the knocking block 57 to work in the knocking function. The end of the knocking block 57 can also be installed with a third ball to cooperate with the stirring of the stirring shaft 21.

[0067] As shown in Figures 1-12 The principle of the high-efficiency coal-containing wastewater treatment device provided in the embodiment is as follows:

[0068] The driving motor 31 is started, as a double-shaft motor, one output shaft drives the transmission sleeve 32 to rotate through the gear member 33, since the stirring shaft 21 is connected with the transmission sleeve 32 by spline, the stirring shaft 21 is further 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;

[0069] The other output shaft of the driving motor 31 drives the circular table 34 to rotate, the electric telescopic rod 36 adjusts the relative position between the inclined disc 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 between the inclined disc 35 and the circular table 34, so that the first abutting roller 373 rolls on the outer surface of the inclined disc 35, and further drives the stirring shaft 21 to reciprocate up and down in the transmission sleeve 32 through the connecting member 37;

[0070] When the stirring shaft 21 reciprocates up and down, the reciprocating shaft 41 in the stirring shaft 21 contacts the bottom wall in the sedimentation tank 1 and realizes the reciprocating movement by the deformation of the first return spring 45, during the reciprocating movement of the reciprocating shaft 41, the reciprocating movement of the reciprocating shaft 41 is converted into the reciprocating movement of the first connecting shaft 421 by the abutting cooperation between the first ball 424 and the wave groove 43, the reciprocating movement of the first connecting shaft 421 drives the elastic member 52 and the hook member 53 to approach the sliding seat 51;

[0071] When the hook member 53 is displaced, the second abutting roller 534 on the hook member 53 rolls along the inclined surface of the inclined guide seat 54, with the rolling displacement of the second abutting roller 534, the hook member 53 is driven to approach the sliding seat 51 by the inclined surface of the inclined guide seat 54, and when the hook member 53 returns to the reset position, the sliding seat 51 is extended to the deep part of the second stirring rod 23 by the hooking of the vertical shaft 532 and the hook groove 533, when the hook member 53 returns, with the second abutting roller 534 no longer being extruded by the inclined guide seat 54, the hook member 53 slowly moves away from the sliding seat 51, at this time, the hook member 53 is disconnected with the sliding seat 51, the sliding seat 51 is reset by the deformation of the third return spring 55, the sliding seat 51 resets the blockage on the inner wall of the sedimentation tank 1 by the knocking block 57, so as to avoid the scaling on the inner wall of the sedimentation tank 1.
