Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coal wastewater treatment, and particularly relates to an adjustable water filtering sleeper. BACKGROUND

[0002] In the process of coal production and processing, coal-containing wastewater is a common byproduct, and its treatment is of great significance for environmental protection and resource recycling. At present, the three-stage sedimentation tank system adopted by the company is an effective method for treating coal-containing wastewater. The water-retaining and water-filtering sleepers arranged between the secondary tank and the tertiary tank play a key role in adjusting the water flow rate and promoting water quality purification.

[0003] However, the existing sleeper design has some shortcomings. In order to ensure the turbidity and flow rate of the effluent, all sleepers above the third-stage sleeper need to be provided with corresponding gaps. The adjustment of these gaps is crucial to the operation effect of the entire sedimentation tank system. However, the traditional adjustment method currently adopted, such as lifting the sleepers and setting fixed buckles to replace and fix the sleepers, is not only complicated to operate, but also not conducive to flexible adjustment of the gaps. In addition, due to the long-term effect of gravity and water flow scouring, the sleepers are prone to deformation and sinking, which causes the original gaps to be blocked and affects the filtering effect of the water flow.

At the same time, the application of the hydraulic system and the induction module further enhances the intelligentization and automation level of the device and improves the work efficiency.

[0048] Embodiment 2

[0049] Reference Figures 1-4 For the second embodiment of the application, the difference between this embodiment and the first embodiment is that the fixing piece 105 is designed to be exquisite and powerful, which mainly includes a limiting groove 105d, a limiting plate 105e, an installation groove 105f, an extension spring 105g, a fixed ring 105h, a connecting plate 105i, a sliding block 105j and a fixed groove 105k and the like. These components work together to ensure the fixation and adjustment of the threaded rod 104b.

[0050] Specifically, the fixing piece 105 further includes the limiting groove 105d arranged on the side wall of the fixed rod 105c, the fixed rod 105c has the limiting plate 105e installed at the top end, the limiting plate 105e has the installation groove 105f installed at the top end, the installation groove 105f can be connected with the output end of the motor, and the threaded rod 104b is rotated by the motor.

[0051] Further, the fixing member 105 further comprises a telescopic spring 105g arranged on the side wall of the limiting plate 105e, and the side wall of the fixing rod 105c is sleeved with a fixing ring 105h, one end of the telescopic spring 105g is connected with the limiting plate 105e, and the other end of the telescopic spring 105g away from the fixing rod 105c is connected with the fixing ring 105h.

[0052] Further, the bottom end of the fixing member 105 is provided with a connecting plate 105i, the inner wall of the connecting plate 105i is provided with a sliding block 105j, the inner wall of the sliding block 105j and the fixing ring 105h is provided with a helical thread matched with the helical groove 105b, and the top end of the fixing plate 104a is provided with a fixing groove 105k.

[0053] The remaining structure is the same as that of example 1.

[0054] Operation process: in the initial state, the telescopic spring 105g is in a natural state, and the fixing ring 105h and the sliding block 105j are located in the initial position. When it is necessary to fix the threaded rod 104b, first press the fixing ring 105h downward, which will stretch the telescopic spring 105g and store potential energy. At the same time, the movement of the fixing ring 105h will drive the sliding block 105j to slide in the limiting groove 105d, so as to ensure that the movement trajectory of the fixing ring 105h is stable and controllable, and when the sliding block 105j is about to leave the limiting groove 105d, the pressing action of the fixing ring 105h stops. At this time, by rotating the fixing ring 105h, the matching relationship between the helical thread on the inner wall of the fixing ring 105h and the helical groove 105b is utilized to realize the close engagement between the fixing ring 105h and the threaded rod 104b. At the same time, the bottommost sliding block 105j will also be engaged with the thread in the fixing groove 105k under the action of the rotating force, forming a self-locking structure, so as to realize the firm fixation of the threaded rod 104b. This fixing method is not only simple and convenient, but also has high stability and reliability. It can effectively prevent the threaded rod 104b from loosening or shifting during use, and ensure the stable operation of the whole device. At the same time, due to the adoption of telescopic spring 105g and helical thread and other mechanical structures, the fixing member also has certain self-adaptability and adjustability, which can adapt to different working environments and use requirements.

[0059] Further, the mounting member 203 includes the sliding table 203a arranged on the side wall of the threaded rod 104b, and the top end and the bottom end of the sliding table 203a are provided with the nut 203b, and the nut 203b is rotatably connected with the sliding table 203a.

[0060] Further, the mounting member 203 further includes the connecting groove 203c arranged on the side wall of the sliding table 203a, the connecting groove 203c is provided with the plug 203d inside, and the inner wall of the connecting groove 203c is provided with the hydraulic rod 203e.

[0061] Further, the mounting member 203 further includes the hydraulic cavity 203f arranged at one end of the hydraulic rod 203e, the output rod in the hydraulic cavity 203f is provided with the piston body 203g, and the inside of the hydraulic cavity 203f is provided with the sensing module 203h.

[0062] The remaining structures are the same as those of the second embodiment.

[0063] Operation process: when the device is reused, first pass the threaded rod 104b through the fixed plate 104a, then the slide 203a is set on the circumference side wall of the threaded rod 104b, and the bottom end of the threaded rod 104b is connected with the bottom end of the secondary filter tank 101, when the threaded rod 104b is adjusted to the appropriate position, press the plug-in block 203d on both ends of the slide 203a to retract, then connect the plug-in block 203d with the plug-in slot 202 on the sleeper body 201, when the sleeper is installed, there should be no gap between the two bottom sleepers, which is used to block the sedimented coal slime particles and impurities from entering the next level, while the first drainage gap 204 is arranged between the third and fourth sleeper bodies 201, and the second drainage gap 205 and the third drainage gap 206 are arranged in turn upwards, the gap between the first drainage gap 204, the second drainage gap 205 and the third drainage gap 206 gradually increases, and the adjustment of the drainage gap can be moved by rotating the nut 203b to drive the sleeper body 201, when the whole needs to be adjusted, the threaded rod 104b can rotate to drive the nut 203b to rotate, and the rotating nut 203b can drive the sleeper body 201 to move, when the threaded rod 104b needs to be fixed, press down the fixed ring 105h, the fixed ring 105h stretches the extension spring 105g to store energy, and the sliding block 105j slides in the limiting slot 105d to limit the movement position of the fixed ring 105h, when the sliding block 105j is about to leave the limiting slot 105d, press down and rotate the fixed ring 105h, the rotating fixed ring 105h can effectively drive the screw thread on the sliding block 105j and the fixed ring 105h to engage with the screw groove 105b to form a self-locking form, and the sliding block 105j at the bottom end engages with the screw thread in the fixed slot 105k to form a self-locking, thereby forming a fixed on the threaded rod 104b, when the sleeper body 201 deforms, since the hydraulic rod 203e is installed at the maximum value at this time, it will not move, and the sleeper body 201 will sag and rise, which will cause the gap to become smaller and affect the drainage efficiency, therefore, two sensing modules 203h are arranged inside the hydraulic chamber 203f, the piston body 203g will not trigger the sensing module 203h within the normal use range of the interval sensing module 203h, when the sleeper body 201 rises or sags, the side or the length will be shortened, so the piston body 203g will move within the interval of the sensing module 203h, when the deformation range of the sleeper body 201 exceeds the set range, the piston body 203g will trigger the sensing module 203h, the sensing module 203h reminds the staff that the sleeper needs to adjust the gap or needs to be replaced, when the sleeper body 201 needs to be replaced, only the sleeper body 201 is extruded to one end, so that the hydraulic rod 203e retracts, and the other end can be separated from the plug-in block 203d, thereby completing the replacement of the sleeper body 201.
