Description

Technical Field

[0001] The utility model relates to the technical field of coal water treatment, in particular to an integrated coal-containing wastewater treatment device. Background Art

[0002] Coal-containing wastewater is the coal-containing wastewater discharged from the flushing of the coal transportation system of the power plant and the coal-containing rainwater collected in the coal yard area and the coal unloading area during rainfall. The coal-containing wastewater contains a high amount of suspended matter, mainly coal powder. Since the particles of coal powder are very fine, it is difficult to settle naturally. At this stage, the treatment of suspended matter in coal-containing wastewater mostly adopts the method of adding drugs, such as adding PAC and PAM, so that the coal-containing wastewater can be treated to meet the emission standards and reuse standards, and then used in water use areas with low water quality requirements such as desulfurization water, coal yard spraying, dry ash humidification, and ash yard spraying.

[0003] When the existing integrated coal-containing wastewater treatment equipment discharges sludge, due to the lack of obstruction, it is inevitable that a part of the clean water on the top of the equipment will be discharged at the same time, which greatly reduces the amount of clean water retained in the equipment. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an integrated coal-containing wastewater treatment device to solve the technical problem that a part of the equipment will discharge clean water during sewage discharge.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an integrated coal-containing wastewater treatment equipment, including a treatment box, one side of the treatment box is fixedly connected to a sedimentation tank, and door stop mechanisms are arranged on the inner walls on both sides of the sedimentation tank, and the door stop mechanism includes an outer door frame, and the inner walls on both sides of the outer door frame are rotatably connected to a first door stop and a second door stop respectively, one side of the first door stop is fixedly connected to a first sealing strip, and one side of the second door stop is fixedly connected to a second sealing strip, and one side of the first sealing strip and the second sealing strip are both provided with a toothed structure.

[0006] By adopting the above technical solution and setting up a door stop mechanism, effective control of sludge discharge inside the sedimentation tank is achieved. The first door stop and the second door stop in the door stop mechanism can be closed when sewage needs to be discharged to form a closed sewage discharge space to prevent clean water from being discharged by mistake.

[0007] Furthermore, both sides of the top of the sedimentation tank are fixedly connected with a bearing platform, and the top of the bearing platform is fixedly connected with a motor.

[0008] By adopting the above technical solution, by setting bearing platforms on both sides of the top of the sedimentation tank, a stable installation foundation is provided for the motor, so that the motor can run stably and its normal operation will not be affected by other external factors.

[0009] Furthermore, a first pull rope is wound around the output end of the motor, and one end of the first pull rope is fixedly connected to the outer door frame.

[0010] By adopting the above technical solution, the first pull rope wound around the output end of the motor is fixedly connected to the outer door frame, so that the motor can directly control the door stop mechanism, ensuring that the power output by the motor is directly and accurately transmitted to the door stop mechanism.

[0011] Furthermore, the door stop mechanism is provided in two groups, and the two groups of door stop mechanisms are provided in a mirror image structure.

[0012] By adopting the above technical solution, by setting up two sets of door stop mechanisms and making them into mirror-image structures, reliable sealing and leakage prevention of the sedimentation tank are achieved, thereby enhancing the sealing and stability of the sedimentation tank.

[0013] Furthermore, a through hole is formed on the second door stopper, and a baffle is rotatably connected to one side of the through hole via a torque shaft.

[0014] By adopting the above technical solution, by opening a through hole on the second door stopper and rotating the connected baffle on one side through a torque shaft, a more flexible control method is provided for the injection of clean water after the sludge in the sedimentation tank is emptied. When clean water needs to be injected, the baffle can be opened so that the clean water can be discharged smoothly through the through hole.

[0015] Furthermore, a fixing block is fixedly connected to one side of the top of the baffle, and a second pull rope is fixedly connected to one side of the fixing block.

[0016] By adopting the above technical solution, by fixing a fixed block on one side of the top of the baffle and fixing a second pull rope on one side of the fixed block, an operator can control the opening and closing of the baffle by pulling the second pull rope, thereby achieving precise control of watering.

[0017] Furthermore, a guide block is sleeved on the outer side of the second pull rope, and the guide block is fixedly connected to the outer door frame.

[0018] By adopting the above technical solution, by sleeved a guide block on the outside of the second pull rope and fixedly connecting the guide block to the outer door frame, a stable guide and support is provided for the second pull rope, ensuring that the second pull rope can maintain a stable path during movement, avoiding the normal operation of the equipment being affected by the pull rope getting stuck.

[0019] Furthermore, one end of the second pull rope is wound and connected to an output end of the motor.

[0020] By adopting the above technical solution, by winding and connecting one end of the second pull rope with the output end of the motor, automatic control of the baffle by the motor is achieved, so that the motor can directly drive the opening and closing of the baffle without manual operation, thereby improving the degree of automation of the equipment.

[0021] Furthermore, one side of the baffle is fixedly connected to a limiting block.

[0022] By adopting the above technical solution, by fixing a limit block on one side of the baffle, a clear limit is provided for the rotation of the baffle, ensuring that the baffle can accurately stop at the predetermined position during the opening and closing process, and will not damage the equipment or affect the normal operation of the equipment due to excessive rotation.

[0023] Furthermore, the motor is electrically connected to an external power source.

[0024] By adopting the above technical solution, by electrically connecting the motor and the external power supply, a stable and continuous power supply to the motor is ensured.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model sets a door stop mechanism. When the sludge in the sedimentation tank needs to be discharged, the motor can be started, and the motor releases the first pull rope to control the closing of the door stop mechanism. The design of the door stop mechanism cleverly utilizes the resistance of water, so that the first door stop and the second door stop can be in an open state during the closing process, which not only reduces the resistance during the lowering process, but also facilitates the rapid discharge of clean water inside the sedimentation tank. When the two outer door frames are closed, the first door stop and the second door stop are also closed, and the first sealing strip and the second sealing strip are meshed with each other to form an effective seal, thereby preventing the leakage of clean water, retaining more clean water resources, and improving the retention rate of clean water;

[0027] 2. The utility model can effectively control the water flow in the sedimentation tank after the sewage is discharged by setting through holes and baffles. When the motor is started, the baffle is driven to rotate through the second pull rope in the guide block to expose the through hole, so that the clean water on the top can be poured into the cavity after the sewage is discharged, effectively reducing the pressure difference on both sides, providing convenience for the lifting of the motor, and improving the overall use efficiency of the equipment.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The following describes an embodiment of the utility model based on its overall structure.

[0035] Embodiment 1:

[0036] An integrated coal-containing wastewater treatment equipment, such as Figure 1-Figure 4 As shown, it includes a processing box 1, one side of the processing box 1 is fixedly connected to a sedimentation tank 2, and door stop mechanisms 3 are arranged on the inner walls of both sides of the sedimentation tank 2. The door stop mechanism 3 includes an outer door frame 301, and the inner walls of both sides of the outer door frame 301 are rotatably connected to a first door stop 302 and a second door stop 303, respectively. One side of the first door stop 302 is fixedly connected to a first sealing strip 304, and one side of the second door stop 303 is fixedly connected to a second sealing strip 305. One side of the first sealing strip 304 and the second sealing strip 305 are both arranged with a toothed structure. By setting up the door stop mechanism 3, effective control of sludge discharge inside the sedimentation tank 2 is achieved. The first door stop 302 and the second door stop 303 in the door stop mechanism 3 can be closed when sewage needs to be discharged to form a closed sewage discharge space to prevent clean water from being discharged by mistake. At the same time, the tooth-shaped structure design of the first sealing strip 304 and the second sealing strip 305 enhances the sealing between the door stops and ensures that clean water will not leak out through the gaps between the door stops, thereby effectively retaining clean water resources and improving the efficiency of wastewater treatment and resource utilization.

[0037] See also Figure 1 and Figure 2A bearing platform 12 is fixedly connected to both sides of the top of the sedimentation tank 2, and a motor 4 is fixedly connected to the top of the bearing platform 12. By arranging the bearing platforms 12 on both sides of the top of the sedimentation tank 2, a stable installation foundation is provided for the motor 4, so that the motor 4 can operate stably and will not be affected by other external factors. At the same time, the fixed installation of the motor 4 makes it easy to link with other components such as the door stop mechanism 3, thereby realizing automatic control.

[0038] See also Figure 1 and Figure 2 A first pull rope 5 is wound around the output end of the motor 4, and one end of the first pull rope 5 is fixedly connected to the outer door frame 301. By fixing the first pull rope 5 wound around the output end of the motor 4 to the outer door frame 301, direct control of the door stop mechanism 3 by the motor 4 is achieved, which can ensure that the power output by the motor 4 is directly and accurately transmitted to the door stop mechanism 3. At the same time, using the pull rope as a transmission method not only reduces the complexity of mechanical transmission, but also reduces maintenance costs, making the opening and closing of the door stop mechanism 3 faster and more reliable, thereby improving the overall operation efficiency and stability of the wastewater treatment equipment.

[0039] See also Figure 1 There are two groups of door stop mechanisms 3, and the two groups of door stop mechanisms 3 are arranged in a mirror structure. By arranging two groups of door stop mechanisms 3 and making them in a mirror structure, reliable sealing and leakage prevention of the sedimentation tank 2 are achieved, and the sealing and stability of the sedimentation tank 2 are enhanced. At the same time, the setting of the mirror structure also makes the equipment more symmetrical and balanced in structure, which is beneficial to improving the service life and reliability of the equipment.

[0040] See also Figure 1 and Figure 2 The motor 4 is electrically connected to the external power supply, thereby ensuring that the motor 4 has a stable and continuous power supply. At the same time, the connection of the external power supply allows the device to continue to work for a long time without being limited by the internal power supply capacity.

[0041] The implementation principle of the utility model is: first, when the sludge in the sedimentation tank 2 needs to be discharged, the motor 4 is started, and the motor 4 releases the first pull rope 5, so that the door stop mechanism 3 begins to close. At this time, due to the resistance of the water, the first door stop 302 and the second door stop 303 are in an open state, reducing the resistance to lowering, and at the same time facilitating the rapid discharge of the clean water inside. When the two outer door frames 301 are closed, the first door stop 302 and the second door stop 303 are also closed. At this time, the first sealing strip 304 and the second sealing strip 305 are meshed with each other to form a seal to prevent clean water leakage, and then the drain valve is opened to discharge the precipitated sludge while retaining more clean water.

[0042] Embodiment 2:

[0043] See also Figure 4 A through hole 6 is provided on the second door stopper 303, and a baffle 7 is rotatably connected to one side of the through hole 6 through a torsion shaft. By providing a through hole 6 on the second door stopper 303 and rotatably connecting the baffle 7 on one side thereof through a torsion shaft, a more flexible control method is provided for the injection of clean water after the sludge in the sedimentation tank 2 is emptied. When clean water needs to be injected, the baffle 7 can be opened so that the clean water can be smoothly discharged through the through hole 6. At the same time, the baffle 7 is connected through the torsion shaft and can be automatically reset when water injection is not needed to close the through hole 6, thereby preventing clean water from leaking from the through hole 6 and ensuring the sealing of the sedimentation tank 2.

[0044] See also Figure 4 A fixing block 8 is fixedly connected to one side of the top of the baffle 7, and a second pull rope 9 is fixedly connected to one side of the fixing block 8. By fixing the fixing block 8 to one side of the top of the baffle 7 and fixing the second pull rope 9 to one side of the fixing block 8, the operator can control the opening and closing of the baffle 7 by pulling the second pull rope 9, thereby achieving precise control of watering. At the same time, the use of pull rope control simplifies the structure of the equipment, reduces maintenance costs, and improves the reliability of the equipment.

[0045] See also Figure 4 A guide block 10 is sleeved on the outer side of the second pull rope 9, and the guide block 10 is fixedly connected to the outer door frame 301. By sleeved the guide block 10 on the outer side of the second pull rope 9 and fixedly connected the guide block 10 to the outer door frame 301, a stable guide and support is provided for the second pull rope 9, ensuring that the second pull rope 9 can maintain a stable path during movement, avoiding the normal operation of the equipment being affected by the pull rope getting stuck. At the same time, the setting of the guide block 10 also reduces the friction between the second pull rope 9 and other parts of the equipment, thereby extending the service life of the pull rope, improving the reliability and durability of the equipment, and reducing maintenance costs.

[0046] See also Figure 4 One end of the second pull rope 9 is wound and connected with the output end of the motor 4. By winding and connecting one end of the second pull rope 9 with the output end of the motor 4, the automatic control of the baffle 7 by the motor 4 is realized, so that the motor 4 can directly drive the opening and closing of the baffle 7 without manual operation, thereby improving the degree of automation of the equipment. At the same time, the control ability of the motor 4 can ensure that the baffle 7 is opened or closed accurately and quickly when needed, thereby improving the efficiency and reliability of wastewater treatment.

[0047] See also Figure 4A limit block 11 is fixedly connected to one side of the baffle 7. By fixing the limit block 11 on one side of the baffle 7, a clear limit is provided for the rotation of the baffle 7, ensuring that the baffle 7 can accurately stop at a predetermined position during the opening and closing process, and will not damage the equipment or affect the normal operation of the equipment due to excessive rotation. At the same time, the setting of the limit block 11 also enhances the safety of the equipment, prevents the baffle 7 from excessive rotation due to unexpected circumstances, thereby avoiding possible damage to the equipment.

[0048] The implementation principle of the utility model is: first, when the sewage is discharged, the sewage outlet is closed, the motor 4 is started, and the second pull rope 9 in the guide block 10 drives the baffle 7 to overcome the resistance of the torque shaft and drive the baffle 7 to rotate, exposing the through hole 6, so that the clean water on the top can be poured into the cavity after the sewage is discharged, reducing the pressure difference on both sides, and facilitating the lifting of the motor 4. Then the motor 4 continues to rotate and pulls the second pull rope 9. At this time, the baffle 7 and the limit block 11 abut against each other, so that the baffle 7 stops moving, and the motor 4 continues to move, driving the entire door stop mechanism 3 to rise, completing the folding of the entire equipment.

[0049] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.
