Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline filtration technology, specifically to a carbon source addition pipeline filtration device for treating leather tanning wastewater. Background Technology
[0002] Tanning wastewater refers to the wastewater discharged during the tanning process. The tanning process includes multiple steps, such as salting animal hides, soaking in water, adding lime, removing flesh, dealkalizing, tanning (using tannins or chromium), softening with fat, and the final dyeing process. The chemicals used in each step and the byproducts generated will become part of the wastewater.
[0003] In the treatment of tannery wastewater, carbon sources are primarily used in the biological treatment stage to promote the growth and metabolic activities of microorganisms. Biological treatment is an important method in wastewater treatment, purifying water quality by utilizing microorganisms to decompose organic matter.
[0004] Currently, when adding carbon sources to tannery wastewater treatment ponds, the carbon sources are often added quantitatively in batches from an external carbon source storage tank via metering pumps and pipelines. However, carbon sources inevitably carry or generate some impurities during the initial preparation process, transportation process, and storage in the external carbon source storage tank. These impurities adhere to the metering pump when passing through it, which not only affects the metering and addition of carbon sources but may even damage the metering pump. Existing carbon source addition pipelines do not have the function of treating and filtering these impurities, which is inconvenient. Utility Model Content

The other ends of the two limiting components are respectively connected to the side walls of the two support plates. The outer wall of the rotating shaft is rotatably connected to the inner wall of the support plate through which it passes. The lower end of the support frame is sleeved and fixedly connected to the outer wall of the middle part of the rotating shaft. The upper end of the support frame is fixedly connected to the outer wall of the temporary storage tube.
[0008] Furthermore, the limiting component includes a limiting strip and two limiting blocks. Both limiting blocks are fixedly connected to the side wall of the support plate. The middle part of the limiting strip is fixedly connected to one end of the rotating shaft. The end of the limiting strip is located between the two limiting blocks, and the side wall of the limiting strip abuts against the side wall of the limiting block.
[0009] Furthermore, the filter assembly includes a filter tube and a filter screen. One end of the filter tube is fixedly connected to one end of the temporary storage tube, and the other end of the filter tube abuts against one end of the V-shaped diverter tube.

[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] This carbon source dosing pipeline filtration device for treating tannery wastewater uses two V-shaped diversion pipes installed between two main pipelines, with valves installed at both ends of the two V-shaped diversion pipes.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Please see Figures 1-6 A carbon source dosing pipeline filtration device for treating tanning wastewater includes a base 4 installed between two main pipelines 1. Each of the two main pipelines 1 has a V-shaped diversion pipe 2 fixedly connected to one adjacent end. Each of the two V-shaped diversion pipes 2 has a valve 3 installed inside both ends. The base 4 is located between the two V-shaped diversion pipes 2. Two support plates 5 are fixedly connected to the upper surface of the base 4. Two rotating components are connected between the two support plates 5. Each of the two rotating components has a temporary storage pipe 7 connected to one end of each of the two V-shaped diversion pipes 2 via flanges. A filter component is connected to one end of the temporary storage pipe 7. The other end of the filter component abuts against one end of one of the V-shaped diversion pipes 2.
[0025] like Figures 1 to 6As shown, in the carbon source dosing pipeline filtration device for tanning wastewater treatment of this utility model, during pipeline installation, two temporary storage pipes 7 are respectively installed at both ends of two V-shaped diversion pipes 2, thereby forming two connected pipelines between the two ends of the two V-shaped diversion pipes 2, such as pipeline No. 1 and pipeline No. 2. In actual use, firstly, the two valves 3 on pipeline No. 1 between the two V-shaped diversion pipes 2 are opened, while the two valves 3 at both ends of pipeline No. 2 remain closed. At this time, the carbon source from the external carbon source storage tank will preferentially enter the V-shaped diversion pipe 2 upstream of pipeline No. 1, then enter the temporary storage pipe 7, and then enter the downstream V-shaped diversion pipe 2 from the temporary storage pipe 7, and then flow into the metering pump from the downstream main pipeline 1. Since the carbon source entering the metering pump passes through the filter assembly between the temporary storage pipe 7 and the upstream V-shaped diversion pipe 2, the impurities contained in the carbon source will be filtered by the filter assembly, thereby reducing the probability and degree of damage to the metering pump.
[0026] After a period of use, the filtration effect of the filter components in Pipeline 1 decreases. First, the valves 3 on the two V-shaped diversion pipes 2 of Pipeline 1 are closed to block the subsequent carbon source from passing through. At this time, there is still a certain amount of carbon source inside the temporary storage pipe 7. As the metering pump continues to work, it will preferentially draw carbon source from the inside of this temporary storage pipe 7. When the carbon source inside the temporary storage pipe 7 is used up, the valve 3 on the downstream V-shaped diversion pipe 2 of Pipeline 1 is closed. Then, the two valves 3 upstream and downstream of Pipeline 2 are opened to allow the carbon source inside the upstream main pipe 1 to flow normally through Pipeline 2, so as to achieve the same effect as in Pipeline 1.
[0027] During the filtration of the carbon source through Pipeline No. 2, the flange connection between the temporary storage tube 7 and the two V-shaped diversion tubes 2 at both ends is loosened. Then, the temporary storage tube 7 is rotated to one side using the rotating assembly. At this time, the filter assembly at the end of the temporary storage tube 7 can be cleaned normally. After cleaning, the temporary storage tube 7 is rotated back to its original position using the rotating assembly, and then the flange is tightened back to the V-shaped diversion tube 2. After that, it is ready to wait for the filter assembly inside Pipeline No. 2 to be cleaned, so that it can be replaced. It is simple and convenient.
[0028] It should be noted that the carbon source storage tank and metering pump mentioned above are existing mature technologies, so they will not be described in detail here.
[0029] like Figures 1-5As shown, the rotating assembly includes a support frame 6, a rotating shaft 9, and two limiting components. The two ends of the rotating shaft 9 pass through one end of the two support plates 5 and are respectively connected to the two limiting components. The other ends of the two limiting components are respectively connected to the side walls of the two support plates 5. The outer wall of the rotating shaft 9 is rotatably connected to the inner wall of the support plate 5 through which it passes. The lower end of the support frame 6 is sleeved and fixedly connected to the outer wall of the middle part of the rotating shaft 9. The upper end of the support frame 6 is fixedly connected to the outer wall of the temporary storage tube 7.
[0030] More specifically, when it is necessary to control the rotation of the temporary storage tube 7, simply loosen the connection between the temporary storage tube 7 and the two V-shaped diverter tubes 2. Subsequently, since the temporary storage tube 7 is rotatably connected to the rotating shaft 9 through the support frame 6, and the support frame 6 is inclined relative to the support plate 5, when the temporary storage tube 7 separates from the V-shaped diverter tubes 2, the temporary storage tube 7 will automatically unfold to one side due to gravity. After the filter assembly is exposed, it will be blocked by the limiting component, thereby preventing the temporary storage tube 7 from colliding with the ground and being damaged.
[0031] like Figures 1-5 As shown, the limiting assembly includes a limiting strip 11 and two limiting blocks 10. Both limiting blocks 10 are fixedly connected to the side wall of the support plate 5. The middle part of the limiting strip 11 is fixedly connected to one end of the rotating shaft 9. The end of the limiting strip 11 is located between the two limiting blocks 10, and the side wall of the limiting strip 11 abuts against the side wall of the limiting block 10.
[0032] More specifically, when the connection between the temporary storage tube 7 and the V-shaped diverter tube 2 is broken, the temporary storage tube 7 rotates to one side via the rotating shaft 9. At the same time as the rotating shaft 9 rotates, the limiting strip 11 will rotate along with it. When the limiting strip 11 rotates to a certain angle, the limiting strip 11 will abut against the limiting block 10, thereby restricting the temporary storage tube 7 from continuing to rotate.
[0033] In addition, when the filter assembly is cleaned and the temporary storage tube 7 needs to be pushed back to its original position, simply lift the temporary storage tube 7 upwards and rotate it back upwards via the pivot 9. When the limit strip 11 abuts against the side of another limit block 10, the temporary storage tube 7 and the V-shaped diverter tube 2 are also aligned. Then, the tube can be tightened by passing bolts through the flange, which is convenient and quick.
[0034] like Figure 3 and Figure 5 As shown, the filter assembly includes a filter tube 12 and a filter screen 13. One end of the filter tube 12 is fixedly connected to one end of the temporary storage tube 7, and the other end of the filter tube 12 abuts against one end of the V-shaped diverter tube 2. The outer wall of the filter screen 13 is connected to the inner wall of the filter tube 12, and the middle part of the filter screen 13 is aligned with the interior of the V-shaped diverter tube 2 and the temporary storage tube 7.
[0035] More specifically, during use, the carbon source inside the V-shaped diverter 2 passes through the filter screen 13 and enters the filter tube 12, and then enters the temporary storage tube 7 through the filter tube 12.
[0036] like Figure 5 and Figure 6 As shown, a receiving port 14 is provided on the side of the filter tube 12 near the V-shaped diverter 2. The filter screen 13 is located inside the receiving port 14, and the outer wall of the filter screen 13 is slidably connected to the inner wall of the receiving port 14. Several slots 16 are provided on the side wall of the receiving port 14, and several locking blocks 15 are fixedly connected to the side wall of the filter screen 13. The outer walls of the locking blocks 15 are slidably connected to the inner walls of the slots 16 respectively. The locking blocks 15 are fastened to the slots 16 by bolts.
[0037] More specifically, by setting the storage port 14, the filter screen 13 can be supported and stored, while reducing its external space occupation; by setting the slot 16 and the block 15, the connection between the filter screen 13 and the filter tube 12 can be increased, and by bolt connection, the filter screen 13 can be prevented from falling out of the filter tube 12 instantly when the temporary storage tube 7 is unfolded to one side.
[0038] like Figures 1-5 As shown, the temporary storage tube 7 is inclined, and a monitoring sensor 8 is fixedly connected to the inner wall of the lower end of the temporary storage tube 7, while the filter assembly is located at the higher end of the temporary storage tube 7.
[0039] More specifically, by setting up monitoring sensor 8, the remaining carbon source inside the temporary storage tube 7 can be monitored in real time, making it convenient for the outside to know the remaining amount so that the corresponding valve 3 can be closed at the appropriate time. Furthermore, setting the temporary storage tube 7 to be tilted allows the carbon source inside the temporary storage tube 7 to flow away better, making it less likely to waste resources.
[0040] It should be noted that the monitoring sensor 8 can be a piezoresistive liquid level sensor, or other sensors with the same function; there is no specific limitation.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
