Description

Technical Field

[0001] This utility model relates to the field of dosing device technology, and in particular to a dosing device for removing suspended solids from dyeing and printing wastewater. Background Technology

[0002] The dyeing and printing wastewater suspended solids removal dosing device is a specialized piece of equipment used in the treatment of dyeing and printing wastewater by adding chemicals to the wastewater to remove suspended solids. It has the following structure:

[0003] 1. Dosing tank: Used to store the chemicals to be added, with sufficient volume to meet the dosing needs within a certain time period;

[0004] 2. Inlet: Located on the upper surface or side of the dosing tank, it is the channel for the agent to enter the dosing tank. It is usually designed with a suitable diameter to facilitate the pouring of the agent or the delivery of the agent through the pipeline.

[0005] 3. Stirring device: It generally consists of a motor, a stirring shaft and a stirring paddle. The motor provides power to drive the stirring shaft and stirring paddle to rotate, so that the agent is fully and evenly mixed in the dosing tank, ensuring that the concentration of the agent is uniform and improving the effect of the agent.

[0006] 4. Delivery pipelines and valves: Delivery pipelines are used to transport the chemicals in the dosing tank to the corresponding locations in the dyeing and printing wastewater treatment system, while valves are used to control the on / off flow and flow rate of the chemicals, which can be adjusted manually or automatically as needed.

[0007] During the storage and transportation of pharmaceuticals, they are highly susceptible to moisture absorption due to improper control of environmental humidity or other unexpected situations, which can lead to clumping. The clumped pharmaceutical particles have increased size. When these larger particles enter the dosing tank, they are difficult to fully mix with other pharmaceuticals during the stirring process, resulting in uneven dispersion of the pharmaceuticals within the tank. The uneven concentration of the pharmaceuticals cannot fully and evenly mix and react with the wastewater, thus affecting the treatment effect of the dyeing and printing wastewater. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a dosing device for removing suspended solids from dyeing and printing wastewater. This device solves the technical problem that large-particle drugs are difficult to fully mix with other agents during stirring, resulting in uneven dispersion of the agents in the dosing tank. Consequently, agents with uneven concentrations cannot fully and evenly mix and react with the wastewater, thus affecting the treatment effect of dyeing and printing wastewater.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A dosing device for removing suspended solids from dyeing and printing wastewater includes a dosing tank. An inlet is fixedly installed on the upper surface of the dosing tank. A filtration mechanism for filtering the drug is provided on the upper surface of the inlet. The filtration mechanism includes a positioning plate, a receiving cylinder, and a filter plate. The positioning plate is located outside the inlet. The receiving cylinder is slidably connected to the outside of the positioning plate. The filter plate is snapped into the inside of the receiving cylinder and is used for screening the drug. A cover plate is placed on top of the receiving cylinder and is used to close the inlet. The cover plate is slidably connected to the outside of the positioning plate.

[0011] Preferably, a threaded rod is fixedly installed on the upper surface of the positioning plate, and a rotating rod is connected to the external thread of the threaded rod. The rotating rod fits against the outside of the cover plate to ensure the stability of the cover plate's closure.

[0012] Preferably, a limiting ring is fixedly installed inside the storage cylinder to restrict the position of the filter plate. The limiting ring is located below the filter plate to prevent the filter plate from moving downwards and entering the dosing tank.

[0013] Preferably, the feed inlet has a slot on its outside, the positioning plate is engaged inside the slot, the positioning plate has a threaded hole on its outside, the feed inlet has a through hole on the side near the slot, a bolt is rotatably connected inside the through hole, the bolt is threaded inside the threaded hole, the positioning plate has a storage slot on its outside, a locking block is slidably connected inside the storage slot, and the threaded hole is on the outside of the locking block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Slide the receiving cylinder to the outside of the positioning plate and fit it against the upper surface of the feed inlet. Then pour the medicine into the receiving cylinder. During this process, the filter plate inside the receiving cylinder screens the medicine. Larger medicine particles are blocked, while smaller medicine particles that meet the requirements can pass through the filter plate and enter the dosing tank below. This prevents large medicine particles from entering the dosing tank and ensures that the medicine is evenly dispersed in the dosing tank. The medicine with uniform concentration can be fully and evenly mixed and reacted with the wastewater, thereby ensuring the treatment effect of dyeing and printing wastewater.

[0016] 2. The threaded rod and the rotating rod are used together. By rotating, the position of the rod is adjusted on the threaded rod using the principle of the thread, thereby pressing or releasing the cover plate. This allows for convenient and quick control of the cover plate's opening and closing state, while also ensuring the stability of the cover plate's closure. Attached Figure Description

[0025] This application provides a dosing device for removing suspended solids from dyeing and printing wastewater, which effectively solves the technical problem that large-particle drugs are difficult to fully mix with other agents during the stirring process, resulting in the inability to achieve uniform dispersion of the agents in the dosing tank 1, and the inability of agents with uneven concentrations to fully and uniformly mix and react with the wastewater, thus affecting the treatment effect of dyeing and printing wastewater.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the technical solution in this application embodiment effectively solves the technical problem that large-particle drugs are difficult to fully mix with other agents during stirring, resulting in the inability to achieve uniform dispersion of the agents in the dosing tank 1. This leads to unevenly concentrated agents failing to fully and uniformly mix and react with the wastewater, thus affecting the treatment effect of dyeing and printing wastewater. The overall approach is as follows:

[0028] To address the problems existing in the prior art, this utility model provides a dosing device for removing suspended solids from dyeing and printing wastewater, including a dosing tank 1. A feed inlet 2 is fixedly installed on the upper surface of the dosing tank 1. A filter mechanism for filtering the drug is fixedly installed on the upper surface of the feed inlet 2. The filter mechanism includes a positioning plate 3, a receiving cylinder 4, and a filter plate 5. The positioning plate 3 is located outside the feed inlet 2. The receiving cylinder 4 is slidably connected to the outside of the positioning plate 3. The filter plate 5 is snapped into the inside of the receiving cylinder 4 and is used for screening the drug. A cover plate 6 is placed above the receiving cylinder 4 and is used to close the feed inlet 2. The cover plate 6 is slidably connected to the outside of the positioning plate 3. The cover plate 6 is composed of a cylinder and a cuboid. A threaded rod 7 is fixedly installed on the upper surface of the positioning plate 3. A rotating rod 8 is threadedly connected to the outside of the threaded rod 7. The rotating rod 8 is composed of a threaded sleeve and two cuboid plates. The rotating rod 8 is attached to the outside of the cover plate 6.

[0029] The storage tube 4 has a fixedly installed limiting ring 9 for restricting the position of the filter plate 5, and the limiting ring 9 is located below the filter plate 5.

[0030] The feed inlet 2 has a slot 10 on its outside, and the positioning plate 3 is snapped into the inside of the slot 10.

[0031] The positioning plate 3 has a storage groove 14 on its outside. A locking block 15 is slidably connected inside the storage groove 14. A threaded hole 11 is provided on the outside of the locking block 15. A through hole 12 is provided on the side of the feed port 2 near the slot 10. The through hole 12 communicates with the inside of the slot 10. A bolt 13 is rotatably connected inside the through hole 12. The bolt 13 is threadedly connected inside the threaded hole 11.

[0032] Positioning plate 3: Provides a stable mounting base for storage cylinder 4 and other components, ensuring that the filtration mechanism will not shift during operation and guaranteeing the stability of drug filtration;

[0033] Storage cylinder 4 and filter plate 5: Storage cylinder 4 is used to hold the medicine to be filtered. At the same time, storage cylinder 4 is slidably connected to the outside of positioning plate 3, which makes it easy to disassemble when the medicine accumulated on filter plate 5 needs to be cleaned. Filter plate 5 sieves the medicine poured into storage cylinder 4 and can effectively intercept larger drug particles.

[0034] Limiting ring 9: Used to limit the position of filter plate 5, preventing it from falling downwards and ensuring the stability of the filtration effect;

[0035] Cover plate 6: After the drug is added, it is used to seal the inlet 2 to prevent other objects from entering the inside of the dosing tank 1 through the storage cylinder 4 when the dosing device is working, and to avoid impurities from mixing into the drug and affecting the treatment effect of dyeing and printing wastewater.

[0036] Threaded rod 7 and rotating rod 8: The threaded rod 7 and the rotating rod 8 are used together. By rotating, the position of the rod on the threaded rod 7 is adjusted by utilizing the thread principle, thereby achieving the pressing or loosening of the cover plate 6, and conveniently and quickly controlling the closed and open state of the cover plate 6.

[0037] Storage slot 14, locking block 15, locking groove 10 and threaded hole 11: The threaded hole 11 is opened on the outside of the locking block 15. When the threaded hole 11 is damaged, the connection between the positioning plate 3 and the locking groove 10 is released, and then the connection between the locking block 15 and the storage slot 14 is released.

[0038] Bolt 13: It connects to the threaded hole 11 of the clamping block 15 through the through hole 12 of the feed port 2, so as to achieve tight fixation between the positioning plate 3 and the feed port 2. It is simple and convenient to operate, easy to install and disassemble, and beneficial to the maintenance and replacement of parts of the equipment.

[0039] Working principle:

[0040] First, insert the card block 15 into the inside of the storage slot 14. At this time, insert one end of the positioning plate 3 into the inside of the card slot 10. Then, connect the bolt 13 through the through hole 12 and the threaded hole 11. At this time, the positioning plate 3 is installed. Insert the filter plate 5 into the inside of the storage cylinder 4 and push the filter plate 5 to adhere to the upper surface of the limiting ring 9. Then, slide the storage cylinder 4 to the outside of the positioning plate 3 and adhere to the upper surface of the feed port 2. At this time, pour the medicine into the storage cylinder 4. During this process, the filter plate 5 in the storage cylinder 4 screens the medicine. Larger medicine particles are blocked, and smaller medicine particles that meet the requirements can pass through the filter plate 5 into the dosing tank 1 below, thereby avoiding the large medicine particles from affecting the uniformity of stirring.

[0041] The second step is to pull the storage cylinder 4 upwards when too much medicine accumulates on the upper surface of the filter plate 5 to disconnect the storage cylinder 4 from the positioning plate 3. At this time, the medicine can be poured out, and then the storage cylinder 4 can be installed back. After the medicine is added, the cover plate 6 is slidably connected to the outside of the positioning plate 3, and the rotating rod 8 is threadedly connected to the outside of the threaded rod 7 to restrict the movement of the cover plate 6. At this time, the cover plate 6 closes the opening at the upper end of the storage cylinder 4, thereby preventing other objects from entering the inside of the dosing tank 1 through the storage cylinder 4 when the dosing device is working.

[0042] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
