Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a flocculant spraying device for wastewater sedimentation treatment. Background Art

[0002] With the development of my country's pharmaceutical industry, pharmaceutical wastewater has gradually become one of the important pollution sources. In order to treat wastewater and recover the renewable components in wastewater, physical treatment, i.e. fly ash or activated carbon adsorption, chemical treatment, i.e. adding flocculants to the water, is generally used to make the colloidal particles in the wastewater lose stability and condense into large particles for easy precipitation, separation and removal, or biological treatment, i.e. the perfect combination of biofilm method and activated sludge method, can solve the pollution problem and achieve economic benefits at the same time.

[0003] The chemical treatment method in the prior art is generally used in conjunction with a flocculant spraying device, that is, by placing flocculant particles inside a stirring barrel, and then using a motor to drive a stirring rod to stir the flocculant particles to form a flocculant solution, and then spraying the flocculant solution into the wastewater pool through a drainage pump, so that the impurities in the wastewater can form granules or clumps, thereby precipitating.

[0004] In actual use, after spraying, the stirring rod needs to be cleaned to prevent it from being corroded, so that when it is used next time, there will be impurities in the flocculant solution, which will affect the sedimentation of the wastewater. However, the traditional stirring rod is fixed with a single bolt, and after long-term use, the bolt will become loose. At this time, stirring will cause the stirring rod to fall off, which will damage the machine body and make the use cost higher. Utility Model Content

[0027] When installing the connecting shaft 5, the plug-in block 4 is inserted into the interior of the rotating shaft 3, and the bolt 7 is screwed into the interior of the rotating shaft 3, so that the bolt 7 can pass through the plug-in block 4. At this time, the bolt 2 9 is screwed into the interior of the threaded groove 8, so that the bolt 2 9 can be connected with the bolt 1 7. Under the joint action of the bolt 1 7 and the bolt 2 9, the bolt 1 7 and the bolt 2 9 will not loosen easily, so that the plug-in block 4 is more stably connected, so that the connecting shaft 5 will not fall off easily when rotating, so that the stirring rod 6 can stir more stably, so that the use of the device is safer and more economical.

[0028] Embodiment 2

[0029] On the basis of the first embodiment, in order to realize the convenient disassembly and cleaning of the stirring rod 6, two installation grooves 10 are opened inside the connecting shaft 5, and the top of the connecting shaft 5 is rotatably connected to the rotating rod 11. The connecting shaft 5 limits the rotating rod 11, so that the rotating rod 11 can operate smoothly. Two pull ropes 12 are fixedly connected to the outside of the rotating rod 11. The outside of the pull rope 12 is slidably connected to the inside of the installation groove 10. The installation groove 10 limits the internal pull rope 12, so that the pull rope 12 can be smoothly curved. The outside of the pull rope 12 is provided with a spring. 13, one end of the pull rope 12 away from the rotating rod 11 is fixedly connected with a block 14, one end of the spring 13 is fixedly connected to the inner wall of the installation groove 10, and the other end of the spring 13 is fixedly connected to the side of the block 14 close to the pull rope 12, the outside of the block 14 is slidably connected to the inside of the installation groove 10, and the installation groove 10 limits the block 14, so that the block 14 can slide smoothly, and the left and right sides of the inside of the connecting shaft 5 are provided with slots 15, the installation groove 10 is connected with the slot 15, and the block 14 passes through the two connecting blocks 16 and is engaged with the inside of the slot 15.

[0030] When it is necessary to disassemble the stirring rod 6, by rotating the stirring rod 6, the stirring rod 6 can wrap the pull rope 12 around the outside of the rotating rod 11, so that the pull rope 12 can pull the block 14 to squeeze the spring 13 to deform, so that the block 14 can fall off from the inside of the slot 15 and the connecting block 16. At this time, the two stirring rods 6 are pulled away from each other to make the stirring rod 6 convenient to disassemble, so that the stirring rod 6 can be conveniently cleaned, so that the stirring rod 6 will not affect the formation of the flocculant solution due to the messy cleaning, so that the flocculant solution has a higher precipitation quality for the wastewater. When it is necessary to install the stirring rod 6, the connecting block 16 is inserted into the inside of the connecting shaft 5. At this time, by loosening the rotating rod 11, the spring 13 can be reset, so that the spring 13 can push the block 14 to penetrate the connecting block 16 and engage with the inside of the slot 15, so that the stirring rod 6 can be conveniently installed.

[0031] Embodiment 3

[0032] On the basis of Example 2, in order to achieve a more stable installation of the stirring rod 6, two polypropylene plugs 18 are fixedly connected to the proximal ends of the stirring rods 6 on the front and rear sides, and the polypropylene plugs 18 on the left and right sides are symmetrically distributed. Two placement grooves 17 are provided on the front and rear sides of the connecting shaft 5, and the polypropylene plugs 18 are inserted into the inside of the placement grooves 17. A plurality of protrusions are fixedly connected to the outside of the polypropylene plugs 18, and the protrusions fit into the inside of the placement grooves 17, thereby making the installation of the stirring rod 6 more stable.

[0033] When the stirring rod 6 needs to be installed, the polypropylene plug 18 is inserted into the placement groove 17. During the process of entering the placement groove 17, the external protrusion of the polypropylene plug 18 will be deformed. When the polypropylene plug 18 completely enters the placement groove 17, the placement groove 17 can be reset, so that the external protrusion of the polypropylene plug 18 can completely contact the inside of the placement groove 17. Since the polypropylene plug 18 has elastic potential energy and is used in conjunction with the card slot 15, the stirring rod 6 will not easily fall off from the inside of the connecting shaft 5 when it rotates.

[0034] In actual use, by inserting the plug-in block 4 into the interior of the rotating shaft 3, and then screwing the bolt 7 into the interior of the rotating shaft 3, the bolt 7 can penetrate the plug-in block 4, and then screwing the bolt 2 9 into the interior of the rotating shaft 3 and the threaded groove 8, so that the bolt 2 9 and the bolt 7 can restrict each other, so that the bolt 7 and the bolt 2 9 will not loosen easily, and the plug-in block 4 is installed more stably, thereby greatly reducing the probability of damage to the body 1 due to loose bolts, and making the device more economical to use.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
