Description

Technical Field

[0001] This utility model relates to the field of coal slurry water recycling technology, specifically, to a coal slurry water recycling device for coal washing. Background Technology

[0002] Coal slurry water mainly comes from industrial wastewater generated during the wet coal preparation process. This wastewater contains a large amount of coal powder and mud. Currently, the treatment method for coal slurry water is to first filter the coal slurry water, and then add chemicals to the filtered coal slurry water to cause flocculation and sedimentation. The treated coal slurry water can be used for fire fighting and greening irrigation.

[0003] For example, the coal slurry water treatment system disclosed in patent CN221971343U can achieve uniform mixing of reagents and coal slurry water and good sedimentation effect, greatly improving the efficiency of coal slurry water treatment. However, in actual use, the position of the mixing rod is inconvenient to adjust. When the mixing shaft drives the mixing rod to mix, the mixing rod can only mix the same position, resulting in a large mixing blind zone in the mixing shell. This leads to poor mixing effect of coal slurry water and reagents in the blind zone, and therefore needs improvement. Utility Model Content

A driving component is provided on the side wall of the processing box, and the rotation of the rotating rod drives the driving component to drive the threaded rod to rotate.

[0013] Preferably, one end of both the rotating rod and the threaded rod extends out of the processing box;

[0035] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0036] The following is in conjunction with the appendix Figures 1-6 This embodiment will be described in further detail.

[0037] like Figure 1-6 As shown, a coal slurry water recycling device for coal washing in this embodiment includes a processing box 100 with an internal cavity 101. A movable stirring shaft 200 is provided inside the cavity 101. Multiple stirring rods 201 are provided on the stirring shaft 200. A rotating assembly is provided inside the cavity 101. The rotating assembly is used to drive the stirring shaft 200 to rotate.

[0038] The processing box 100 is also equipped with a movable box 110, which is used to hold flocculant. The cavity 101 is equipped with a moving component, and the rotating component is used to drive the moving component to drive the stirring shaft 200 and the box 110 to reciprocate.

[0039] The cavity 101 is equipped with a liftable filter box 120. One end of the filter box 120 is connected to the cavity 101. The upper end of the filter box 120 is equipped with a water inlet pipe 122 that connects to the filter box 120. One end of the filter box 120 is equipped with an inclined filter screen 121 for filtering coal slurry water. The cavity 101 is also equipped with a cleaning component. The rotating component is used to drive the cleaning component to clean the impurities on the filter screen 121.

[0040] In this embodiment, coal slurry water is transported to the filter box 120 through the water inlet pipe 122. The coal slurry water in the filter box 120 passes through the filter screen 121 and falls into the cavity 101. When the coal slurry water passes through the filter screen 121, the filter screen 121 can intercept the impurities in the coal slurry water in the filter box 120, thereby achieving the filtration of the coal slurry water. When the water inlet pipe 122 stops transporting the coal slurry water, the flocculant in the box 110 begins to be added to the coal slurry water in the cavity 101. At the same time, the rotating component starts to work, and the rotating component drives the stirring shaft 200 to rotate. The stirring shaft 200 drives multiple stirring rods 201 to rotate in the cavity 101, thereby achieving the mixing and stirring of the flocculant and the coal slurry water by the stirring rods 201.

[0041] Among them, multiple stirring rods 201 are fixedly installed on the stirring shaft 200 along the length direction of the stirring shaft 200, so that the rotation of the stirring shaft 200 can drive the multiple stirring rods 201 to rotate;

[0042] When the rotating component is working, it can drive the moving component, which in turn drives the rotating stirring shaft 200 to reciprocate within the cavity 101. This allows the stirring shaft 200 to drive multiple stirring rods 201 to stir different positions within the cavity 101. Compared to existing methods, this coal washing slurry water recycling device can reduce the stirring blind zone of the stirring rods 201 during actual use, thereby improving the mixing effect of the stirring rods 201 on the flocculant and coal slurry water.

[0043] When the moving component is working, it can also drive the box 110 to move back and forth on the upper surface of the processing box 100, so that the flocculant in the box 110 can be added to different positions in the cavity 101, thereby avoiding the flocculant being added to the same position all the time, which would make it difficult to mix the flocculant with the coal slurry water, and improving the mixing effect of the flocculant and the coal slurry water.

[0044] Among them, the outer side wall of the box 110 is fixedly installed with corresponding drain pipes 600, and each drain pipe 600 is equipped with a solenoid valve. By opening the solenoid valve, the flocculant in the box 110 can be added into the cavity 101 through the drain pipe 600.

[0045] The filter screen 121 is fixedly installed on the filter box 120. After the filter screen 121 completes the filtration of coal slurry water, impurities in the coal slurry water may adhere to the filter screen 121, causing the filter screen 121 to become clogged and affecting the next use. When the rotating component drives the stirring shaft 200 to rotate, the rotating component can also drive the filter box 120 to vibrate up and down. When the filter box 120 vibrates up and down, the impurities attached to the filter screen 121 will slide along the inclined direction of the filter screen 121 into the filter box 120, thereby preventing impurities from adhering to the filter screen 121 and affecting subsequent use.

[0046] The outer wall of the treatment box 100 is fixedly equipped with a drain pipe 102, and a solenoid valve is installed inside the drain pipe 102. When the solenoid valve is opened, the coal slurry water mixed with flocculant in the cavity 101 can be discharged into the sedimentation tank through the drain pipe 102 for flocculation and sedimentation. After the coal slurry water is treated by flocculation and sedimentation, it can be used for fire fighting and greening irrigation, realizing the recycling of coal slurry water.

[0047] In actual use, the solenoid valves are all 4V210-08 solenoid valves.

[0048] like Figure 1-4 As shown, in this embodiment, the stirring shaft 200 is provided with a groove 401 with openings at both ends, and a locking block 402 is provided in the groove 401.

[0049] The rotating assembly includes a rotating rod 210 disposed in the cavity 101 and fitted onto the stirring shaft 200. The rotating rod 210 is rotatably disposed, and a slot 411 for the locking block 402 to be inserted is provided on the outer side wall of the rotating rod 210. The rotation of the rotating rod 210 is used to drive the stirring shaft 200 to rotate.

[0050] In this embodiment, the locking block 402 is fixedly installed on the side wall of the slot 401, the slot 411 is arranged along the length direction of the rotating rod 210, and the two ends of the rotating rod 210 are rotatably installed on the side wall of the cavity 101 through bearings. When the rotating rod 210 rotates, the rotating rod 210 can drive the stirring shaft 200 to rotate through the cooperation of the slot 411 and the locking block 402, so that the stirring rod 201 on the stirring shaft 200 can be mixed and stirred.

[0051] like Figure 1-6 As shown, in this embodiment, a movable plate 220 is provided inside the cavity 101, and a connecting plate 221 is provided on the lower end face of the movable plate 220. One end of the stirring shaft 200 is rotatably connected to the connecting plate 221. A limiting rod 131 is also provided inside the cavity 101 to limit the movable plate 220.

[0052] The moving component includes a threaded rod 160 that is disposed in the cavity 101 and rotates. A moving plate 220 is threadedly sleeved on the threaded rod 160, so that the rotation of the threaded rod 160 drives the moving plate 220 to reciprocate. A driving component is provided on the side wall of the processing box 100. A rotating rod 210 drives the driving component to drive the threaded rod 160 to rotate.

[0053] In this embodiment, the upper end of the connecting plate 221 is fixedly mounted on the movable plate 220, and one end of the stirring shaft 200 is mounted on the movable plate 220 through a bearing. Two limiting rods 131 pass through the corresponding ends of the movable plate 220 and limit the movable plate 220. When the rotating rod 210 rotates and drives the threaded rod 160 to rotate through the driving component, the rotation of the threaded rod 160 can drive the movable plate 220 to move along the threaded rod 160. The movement of the movable plate 220 can drive the stirring shaft 200 to move through the connecting plate 221, so that the stirring rod 201 on the stirring shaft 200 can mix and stir at different positions.

[0054] A horizontal plate 140 is fixedly installed inside the cavity 101. One end of the threaded rod 160 is mounted on the horizontal plate 140 through a bearing, and the other end of the threaded rod 160 is mounted on a side wall of the cavity 101 through a bearing. One end of the limiting rod 131 is fixedly connected to the horizontal plate 140, and the other end is fixedly installed on a side wall of the cavity 101, thereby realizing the installation of the limiting rod 131 inside the cavity 101.

[0055] The lower end face of the box 110 is fixedly equipped with multiple vertical rods 300, one end of which are connected to the moving plate 220. The moving plate 220 can move the box 110 in the processing direction by moving the vertical rods 300. The upper end face of the processing box 100 is provided with corresponding grooves 231 along the moving direction of the box 110. The lower end face of the box 110 is fixedly equipped with corresponding protrusions 310 that are inserted into the corresponding grooves 231. The grooves 231 limit the movement of the protrusions 310, making the movement of the box 110 more stable.

[0056] The box 110 is fitted with a cover 111, which covers the box 110 to prevent dust in the air from falling into the flocculant when the box 110 is moved.

[0057] In actual use, the threaded rod 160 continuously rotates in both directions. This continuous rotation of the threaded rod 160 is driven by the drive component, thereby enabling the rotating threaded rod 160 to drive the moving plate 220 to reciprocate. In other words, the stirring shaft 200 and the box 110 reciprocate. When the threaded rod 160 rotates forward, it drives the moving plate 220 to move towards the filter box 120. When the threaded rod 160 rotates in reverse, it drives the moving plate 220 away from the filter box 120.

[0058] like Figure 1-3 As shown, in this embodiment, one end of both the rotating rod 210 and the threaded rod 160 extends out of the processing box 100;

[0059] The driving component includes a first synchronous pulley 240 sleeved on the extended end of the rotating rod 210, a second synchronous pulley 250 sleeved on the extended end of the threaded rod 160, and a synchronous belt 320 sleeved between the first synchronous pulley 240 and the second synchronous pulley 250, so that the rotation of the rotating rod 210 drives the threaded rod 160 to rotate.

[0060] In this embodiment, the first synchronous pulley 240 is fixedly mounted on the rotating rod 210, the second synchronous pulley 250 is fixedly mounted on the threaded rod 160, and the two ends of the synchronous belt 320 are respectively sleeved on the first synchronous pulley 240 and the second synchronous pulley 250. When the rotating rod 210 rotates, the first synchronous pulley 240 on the rotating rod 210 can drive the second synchronous pulley 250 to rotate through the synchronous belt 320, that is, the threaded rod 160 rotates.

[0061] In actual use, a mounting shell 150 is fixedly installed on the outer wall of the processing box 100. The protruding ends of the first rotating rod 210 and the threaded rod 160 are both located inside the mounting shell 150. A motor 151 is fixedly installed on the outer wall of the mounting shell 150. The motor 151 is a NEMA 23 stepper motor. The output shaft of the motor 151 is connected to the rotating rod 210, so that the rotating rod 210 can be driven to rotate continuously in both directions by the motor 151.

[0062] like Figure 1-5 As shown, in this embodiment, the cleaning component includes a push rod 211 disposed on the rotating rod 210. The rotating rod 210 drives the push rod 211 to rotate, and the push rod 211 pushes the filter box 120 to rise and fall, thereby cleaning the impurities on the filter screen 121.

[0063] In this embodiment, the push rod 211 is fixedly installed at one end of the rotating rod 210. When the rotating rod 210 rotates, it can drive the push rod 211 to rotate. When the push rod 211 rotates, one end of the push rod 211 will push the filter box 120 to continuously rise and fall, and cause the rising and falling filter box 120 to vibrate to a certain extent, thereby cleaning the impurities accumulated on the filter screen 121 into the filter box 120.

[0064] Among them, a corresponding limiting block 510 is fixedly installed on the side wall of the filter box 120 near the cavity 101, and a fixing plate 500 is fixedly installed on the side wall of the cavity 101. A corresponding guide rod 501 that passes through the limiting block 510 is fixedly installed on the fixing plate 500. The filter box 120 can be lifted and lowered in the cavity 101 through the cooperation of the limiting block 510 and the guide rod 501. When the push rod 211 pushes the filter box 120 to lift and lower, the limiting block 510 and the guide rod 501 are always in a mutually cooperating state.

[0065] The length of the push rod 211 is greater than the length of the stirring rod 201. When the stirring shaft 200 rotates below the filter box 120, the stirring rod 201 on the stirring shaft 200 does not abut against the lower end face of the filter box 120.

[0066] In actual use, when there are a lot of impurities in the filter box 120, the staff can lift the filter box 120 so that the limiting rod 131 slides out from the guide rod 501. At this time, the staff can pour out the impurities in the filter box 120 through the water inlet pipe 122. After pouring, the limiting block 510 needs to be put on the corresponding guide rod 501 to realize the installation of the filter box 120 in the cavity 101.

[0067] In practical use, the following steps are taken: First, coal slurry water is transported to the filter box 120 through the inlet pipe 122. The coal slurry water in the filter box 120 passes through the filter screen 121 and falls into the cavity 101. When the inlet pipe 122 stops transporting the coal slurry water, the solenoid valve in the drain pipe 600 opens. At the same time, the motor 151 drives the rotating rod 210 to rotate. The rotating rod 210 drives the stirring rod 201 through the stirring shaft 200 to mix and stir. When the rotating rod 210 rotates, the rotating rod 210 is connected to the first synchronous wheel 240 and the second synchronous wheel 240. The cooperation between wheel 250 and synchronous belt 320 enables rotating rod 210 to drive threaded rod 160 to rotate. The rotation of threaded rod 160 drives moving plate 220 to move. Moving plate 220 can drive stirring shaft 200 to move through connecting plate 221. At the same time, moving plate 220 drives box 110 to move through vertical rod 300, adding flocculant in box 110 to different positions in cavity 101. After the flocculant is mixed with coal slurry water, the solenoid valve in drain pipe 102 is opened to discharge the mixed mixture into sedimentation tank for flocculation and sedimentation.

[0068] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
