Description

Technical Field

[0001] This utility model specifically relates to the field of mud mixing technology, and more specifically to a mud mixing device that can prevent mud deposition. Background Technology

[0002] In many fields such as wastewater treatment, construction, mining, and oil drilling, mud treatment is a critical and ubiquitous task. Mud is usually a mixture of solid particles and liquid. Due to the influence of gravity, solid particles are prone to sedimentation when left still or flowing slowly.

[0003] Wastewater treatment plants generate a large amount of sludge when treating domestic sewage and industrial wastewater. Sludge deposition can clog treatment equipment such as pipes, pumps, and sedimentation tanks, affecting the normal operation of the entire treatment process. At the same time, this sludge contains a large number of microorganisms, pathogens, and other pollutants. In a long-term oxygen-deficient deposition environment, microorganisms will anaerobically decompose the organic matter in the sludge. This process will produce harmful gases such as hydrogen sulfide and methane, thus causing environmental pollution.

[0004] Existing sewage slurry mixing devices have certain limitations. Some traditional mixing devices have limited mixing range and dead zones, failing to fully mix the entire slurry area, resulting in localized slurry sedimentation. In addition, some existing mixing devices only have mixing functions and cannot simultaneously meet other needs such as adding treatment solutions and adjusting slurry concentration. In practical applications, additional equipment and procedures are often required to complete these operations, increasing the complexity and cost of the process. Utility Model Content

[0005] The purpose of this invention is to provide a mud mixing device that prevents mud deposition. By driving a second lead screw to rotate via a third motor in the moving device, the slider moves the sliding base, achieving overall movement of the mixing device. Combined with the rotation of the mixing shaft, it can comprehensively mix large areas of sewage slurry. The sliding adjustment of the support frame and the rotation function of the mixing shaft work synergistically, allowing for dynamic adjustment based on the real-time state of the sewage slurry. Simultaneously, a quantitative pump delivers treatment solution to the mixing shaft through a solution pipe and a rotary joint, and sprays it out from the nozzle. The solution mixing is completed synchronously during the mixing process, not only preventing mud deposition but also improving the efficiency and quality of sewage slurry treatment and reducing subsequent treatment costs; thus solving the technical problems mentioned in the background art.

[0027] 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.

[0028] Please see Figure 1-6 In this embodiment of the utility model, a sliding seat 2 is included. A support column 3 is fixedly connected to the sliding seat 2, and a support frame 4 is slidably connected to the support column 3. A sleeve 5 is fixedly connected to one end of the support frame 4, and a stirring shaft 6 is provided inside the sleeve 5. A rotary joint 15 is installed at the top of the stirring shaft 6, and a paddle hub 8 is fixedly connected to the bottom. Multiple stirring paddles 9 are fixedly connected to the paddle hub 8. The stirring shaft 6 is connected to a driving device, and multiple spray holes 7 are opened at the bottom of the stirring shaft 6.

[0029] By adopting the above technical solution, the slide 2 provides a movable foundation for the entire device, enabling flexible mixing work in different positions, expanding the mixing coverage area, and avoiding mud deposition due to insufficient local mixing. The sliding connection design of the support column 3 and the support frame 4 allows for convenient adjustment of the height of the mixing shaft 6 and the mixing paddle 9 according to the mud depth or actual working conditions, ensuring that the mixing operation can accurately act on different layers of mud and prevent deposition in all aspects.

[0030] Furthermore, the sleeve 5 supports and positions the stirring shaft 6, ensuring its stable rotation. The rotary joint 15 allows the liquid medicine to be delivered through the metering pump into the hollow channel inside the stirring shaft 6 when it rotates at high speed. Driven by the drive device, the stirring shaft 6 rotates at high speed, and under the action of centrifugal force, the liquid medicine is thrown to all sides through the spray hole 7, promoting the full mixing and reaction of the liquid medicine and mud.

[0031] In this embodiment, the driving device includes a first motor 10, which is fixedly connected to the other end of the support frame 4. Both the drive shaft of the first motor 10 and the stirring shaft 6 at the bottom of the rotary joint 15 are fitted with pulleys 11. The pulleys 11 are horizontally arranged and connected by a belt 16.

[0032] By adopting the above technical solution, the first motor 10 serves as the power source, and the rotation of its transmission shaft is transmitted to the stirring shaft 6 through the pulley 11 and belt 16. During the start-up and operation of the motor, the belt 16 can absorb a certain amount of impact and vibration, avoiding damage to the stirring shaft 6 and other components caused by the impact force that may be brought about by rigid transmission, and ensuring the stability and reliability of the stirring device operation.

[0033] In this embodiment, the stirring shaft 6 is rotatably connected to the sleeve 5, and the interior of the stirring shaft 6 is hollow.

[0034] By adopting the above technical solution, the stirring shaft 6 is rotatably connected to the sleeve 5, so that the stirring shaft 6 can rotate flexibly and smoothly under the drive of the driving device, ensuring that the stirring paddle 9 can efficiently stir the mud.

[0035] Furthermore, the hollow design inside the stirring shaft 6 provides a channel for the delivery of the chemical solution. Combined with the rotary joint 15 and the connected chemical solution pipe 14, the external treatment chemical solution can be delivered through the hollow channel to the spray hole 7 at the bottom of the stirring shaft 6 while the stirring shaft 6 is rotating, and then evenly sprayed into the mud. This not only enables the slow addition of the chemical solution, but also ensures the uniform mixing effect of the wastewater and the chemical solution, thus fully improving the reaction efficiency of the wastewater and the chemical solution.

[0036] In this embodiment, a fixing frame 18 is fixedly connected to the slide 2, and the fixing frame 18 is fixedly connected to the support column 3. A second motor 13 is provided below the fixing frame 18, and the second motor 13 is fixedly connected to the slide 2. A first lead screw 12 is installed at one end of the transmission shaft of the second motor 13.

[0037] By adopting the above technical solution, the second motor 13 drives the first lead screw 12 to rotate. Based on the lead screw transmission principle, the rotational motion of the motor can be converted into linear motion. Combined with the fixing plate 17 that is subsequently threaded to the first lead screw 12, the support frame 4 can slide on the support column 3, thereby flexibly adjusting the height position of the stirring shaft 6 and the stirring paddle 9. When facing sewage tanks of different depths or areas with different sludge deposition conditions, the stirring height can be precisely adjusted according to actual needs to ensure that the stirring paddle 9 is always in the optimal stirring position, giving full play to the stirring effect and effectively preventing sludge deposition.

[0038] In this embodiment, a fixing plate 17 is fixedly connected above the support frame 4, and the fixing plate 17 is installed and slidably connected with the support column 3.

[0039] By adopting the above technical solution, the fixing plate 17 is slidably connected to the support column 3. Combined with the second motor 13 and the first lead screw 12 below the fixing frame 18, when the second motor 13 drives the first lead screw 12 to rotate, the fixing plate 17, which is threadedly connected to the first lead screw 12, will move axially on the support column 3.

[0040] In this embodiment, the first lead screw 12 is disposed on one side of the support column 3 and its bottom is rotatably connected to the fixing frame 18. The first lead screw 12 is threadedly connected to the fixing plate 17.

[0041] By adopting the above technical solution, the first lead screw 12 is threadedly connected to the fixed plate 17. When the second motor 13 drives the first lead screw 12 to rotate, based on the principle of lead screw transmission, the rotational motion of the motor can be converted into the linear motion of the fixed plate 17. Since the fixed plate 17 is fixedly connected to the support frame 4, and the support frame 4 is connected to the stirring shaft 6, the stirring shaft 6 and the stirring paddle 9 can be driven to move up and down along the support column 3, thereby precisely adjusting the stirring height. This allows the stirring device to flexibly adjust the position of the stirring paddle 9 according to the actual working conditions such as the depth of different sewage tanks and the sedimentation of sludge, ensuring that sludge at each depth layer can be effectively stirred.

[0042] In this embodiment, a medicine pipe 14 is installed on the top of the rotary joint 15, and the medicine pipe 14 is fixedly connected to the top of the support column 3. The other end of the medicine pipe 14 is connected to a metering pump.

[0043] By adopting the above technical solution, the liquid pipe 14 installed on the top of the rotary joint 15 provides a channel for the delivery of liquid. During the treatment of sewage slurry, the metering pump draws the liquid from the storage place and delivers it to the rotary joint 15 through the liquid pipe 14. Then, it enters the hollow channel inside the stirring shaft 6 and is finally sprayed evenly into the slurry through the spray hole 7 at the bottom of the stirring shaft 6.

[0044] Furthermore, the chemical solution pipe 14 is connected to a metering pump, which can precisely control the delivery volume of the chemical solution. In different sewage slurry treatment scenarios, the amount of chemical solution added can be accurately controlled by adjusting the parameters of the metering pump according to factors such as the composition, concentration, and degree of sedimentation of the slurry. This helps to ensure that the chemical solution reacts fully with the sewage slurry, improve the slurry treatment effect, and avoid the problems of chemical solution waste or insufficient addition.

[0045] In this embodiment, the bottom of the slide block 2 is provided with a moving device 1. The moving device 1 includes a third motor 101, which is fixedly connected to one end of the moving device 1. A second lead screw 102 is installed on the drive shaft of the third motor 101. Slide rods 103 are provided on both sides of the second lead screw 102, and sliders 104 are slidably connected to the slide rods 103. The sliders 104 are threadedly connected to the second lead screw 102, and the sliders 104 are fixedly connected to the slide block 2.

[0046] By adopting the above technical solution, with the help of the mobile device 1, the stirring device can move flexibly in the sewage tank. The third motor 101 drives the second lead screw 102 to rotate, so that the slider 104, which is threadedly connected to the second lead screw 102, slides along the slide rod 103, thereby driving the slide seat 2 and the stirring components installed on it to move. This avoids the problem of stirring dead corners in traditional stirring devices, and can carry out comprehensive stirring of the entire sewage tank, ensuring that the mud in each area can be fully disturbed, and effectively preventing mud deposition.

[0047] The working principle of this utility model is as follows: First, the third motor 101 in the moving device 1 is started. The transmission shaft of the third motor 101 drives the second lead screw 102 to rotate. The rotation of the second lead screw 102 will cause the slider 104 to move linearly along the slide rod 103. Since the slider 104 is fixedly connected to the slide seat 2, the slide seat 2 will move together with the slider 104, thereby adjusting the position of the stirring device in the sewage tank.

[0048] Then, the second motor 13 is turned on, which drives the first lead screw 12 to rotate. The first lead screw 12 is threadedly connected to the fixed plate 17, and the fixed plate 17 is slidably connected to the support column 3. The rotation of the first lead screw 12 will cause the fixed plate 17 to move up and down along the support column 3. Since the fixed plate 17 is fixedly connected to the support frame 4, and the stirring shaft 6 is installed on the support frame 4, the stirring shaft 6 and the stirring paddle 9 will move up and down together with the fixed plate 17 to achieve flexible adjustment of the stirring height to adapt to mud pools of different depths and mud deposition conditions.

[0049] When the first motor 10 is started, the drive shaft of the first motor 10 drives the pulley 11 on it to rotate. Through the belt 16, the pulley 11 on the bottom stirring shaft 6 of the rotary joint 15 also rotates, thereby driving the stirring shaft 6 to rotate. The bottom of the stirring shaft 6 is fixedly connected to the impeller hub 8. Multiple stirring paddles 9 on the impeller hub 8 will rotate together with the stirring shaft 6 to stir the mud and prevent the mud from settling.

[0050] While the stirring shaft 6 is working, the metering pump starts working, delivering the treatment solution through the solution pipe 14 to the rotary joint 15. Since the stirring shaft 6 is hollow, the solution enters the internal channel of the stirring shaft 6 through the rotary joint 15. Under the action of centrifugal force, the solution is evenly sprayed into the mud from multiple nozzles 7 at the bottom of the stirring shaft 6. Under the stirring action of the stirring paddle 9, the solution and mud are fully mixed, further improving the properties of the mud and enhancing the effect of preventing mud deposition. At the same time, it can also treat harmful substances in the mud.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
