Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an electrolytic manganese wastewater treatment device. Background Technology

[0002] Electrolytic manganese wastewater is wastewater generated during the electrolytic production of metallic manganese. It mainly originates from processes such as rinsing in the electrolysis workshop, cleaning of filter cloths, and absorption of acid mist. It contains pollutants such as total manganese, total chromium, hexavalent chromium, suspended solids, sulfates, and phosphates. It needs to be treated before recycling or discharge in compliance with standards. The treatment process of electrolytic manganese wastewater mainly includes steps such as pretreatment, pH adjustment, coagulation reaction, precipitation separation, oxidation reaction, deep treatment, and sludge recovery. Its core principle is to achieve wastewater purification through chemical precipitation and resource recovery.

[0003] In the existing technology, the pretreatment and coagulation reaction processes in the treatment of electrolytic manganese wastewater cannot effectively collect floating matter and coagulated matter on the water surface, which can easily affect the subsequent wastewater treatment process. Utility Model Content

[0004] The purpose of this invention is to provide an electrolytic manganese wastewater treatment device that has the advantage of effectively collecting floating matter and flocculants in wastewater during pretreatment and coagulation processes. It is not only easy to operate, but also accelerates collection efficiency based on the principle of centrifugal force during coagulation, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrolytic manganese wastewater treatment device, comprising a tank:

[0006] The pool body is equipped with a mixing mechanism for accelerating mixing, and a cleaning mechanism for collecting and cleaning flocculated impurities is provided on the outside of the pool body. The bottom of the pool body is connected to a drain valve pipe.

[0007] The mixing mechanism includes a drive assembly disposed at the top of the pool and a rotating assembly connected to the drive assembly.

[0008] The cleaning mechanism includes a pushing component disposed on both sides of the pool and a supporting component connected to the pushing component. A collecting component is connected through the inside of the supporting component, and a locking component is provided at the connection between the supporting component and the collecting component.

[0009] Preferably, the drive assembly includes a mounting plate fixedly installed on the top of the pool body, and a motor is fixedly installed on the top of the mounting plate.

[0014] Preferably, the locking assembly includes a screw threaded to the outside of the mounting base, and a push block threaded to the inner end of the screw, the push block being inserted into the mounting hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention, through the coordinated arrangement of a mixing mechanism and a cleaning mechanism, can effectively collect and clean the flocculated material generated during the coagulation process. It utilizes centrifugal force during the coagulation process to assist in the collection operation. The mixing mechanism can drive the liquid below to rotate when adding chemical agents for coagulation, thereby accelerating the coagulation process.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides an electrolytic manganese wastewater treatment device, including a tank 1:

[0025] The interior of the tank body 1 is equipped with a mixing mechanism 2 for accelerating mixing, and the exterior of the tank body 1 is equipped with a cleaning mechanism 3 for collecting and cleaning flocculated impurities. The bottom of the tank body 1 is connected to a drain valve pipe 4, which mainly controls the flow rate of the flocculated wastewater and discharges it to the next working area for further treatment.

[0026] The mixing mechanism 2 includes a drive assembly disposed on the top of the tank body 1 and a rotating assembly connected to the drive assembly;

[0027] The cleaning mechanism 3 includes a pushing component and a support component connected to the pushing component on both sides of the pool body 1. The support component has a through-connection to a collection component, and a locking component is provided at the connection between the support component and the collection component.

[0028] Preferred:

[0029] like Figure 2 As shown, the drive assembly includes a mounting plate 21 fixedly installed on the top of the pool body 1. The mounting plate 21 is used to support the rotation of the rotating rod 23 and can also support the motor 22. The motor 22 is fixedly installed on the top of the mounting plate 21. The motor 22 can serve as the rotational driving force in the coagulation process, further driving the rotating rod 23 to complete the rotation operation.

[0030] in:

[0031] like Figure 2As shown, the rotating assembly includes a rotating rod 23 keyed to the output shaft of the motor 22 and a mixing blade 24 bolted to the outside of the rotating rod 23. The rotating rod 23 is rotatably connected to the mounting plate 21. During the rotation of the rotating rod 23, it will also drive the mixing blade 24 to rotate together, thereby fully mixing the wastewater added inside and the chemical agents used for flocculation, and achieving the effect of coagulation. When rotating, it will also generate centrifugal force, so that the flocculated flocs can be driven by centrifugal force to stick to the inner wall of the tank 1.

[0032] It is worth noting that:

[0033] like Figure 3 As shown, the pushing component includes a fixed plate 31 fixedly installed on both sides of the pool body 1. An electric push rod 32 is fixedly installed on the top of the fixed plate 31. The fixed plate 31 is used to install the electric push rod 32, and the electric push rod 32 can raise the height of the collection box 38 by pushing the mounting bracket 33, so as to facilitate subsequent direct cleaning or removal of the flocculent inside.

[0034] further:

[0035] like Figure 4 As shown, the support assembly includes a mounting bracket 33 fixedly installed on the output end of the fixed plate 31 and mounting bases 34 fixed to the top ends of the mounting bracket 33. The mounting bracket 33 and the mounting base 34 are provided with through holes 35 at corresponding positions on their tops. The mounting bracket 33 and the mounting base 34 can not only drive the lifting operation, but also cooperate with the locking assembly to lock and fix the position of the collecting assembly, so as to assist in the adaptation adjustment operation. The through holes 35 facilitate the through sliding of the mounting rod 36 during adjustment.

[0036] Going a step further:

[0037] like Figure 4 As shown, the collection assembly includes a mounting rod 36 installed inside the perforation 35 and a mounting hole 37 opened on the outside of the mounting rod 36. A collection net box 38 is fixedly installed at the bottom end of the mounting rod 36. The mounting rod 36 facilitates the connection of the collection net box 38, and the flocculent material passing through the collection net box 38 is collected and cleaned through the opening. The mounting hole 37 is used to adapt to the push block 310 when the locked position height is reached.

[0038] at last:

[0039] like Figure 4 As shown, the locking assembly includes a screw 39 threaded to the outside of the mounting base 34, and a push block 310 threaded to the inner end of the screw 39. The push block 310 is inserted into the mounting hole 37. The position of the push block 310 can be adjusted by the screw 39 through the threaded connection. The fixed and unfixed operations of the mounting rod 36 can be realized by the driven push block 310.

[0040] First, a preset amount of wastewater is added to the tank 1. Then, a corresponding amount of chemical agent is added according to the amount of wastewater added for flocculation treatment. In order to improve the efficiency and effect of flocculation, the motor 22 is started and the mixing blade 24 is driven to rotate through the rotating rod 23, so as to carry out coagulation operation on the internal liquid. Before this, the actual height position of the collection net box 38 needs to be adjusted in advance to match the amount added inside. The bottom position of the opening of the collection net box 38 should be at the water surface. Since the outside of the collection net box 38 is a mesh, it will separate the flocculent and the wastewater during collection.

[0041] When adjusting the collection net box 38, it is necessary to loosen the screw 39 at the corresponding position in advance and pull the push block 310 to move outward until the push block 310 disengages from the inside of the mounting hole 37 to achieve locking. Then, the mounting rod 36 can be pushed up and down directly to adjust the height of the collection net box 38 at the bottom. Stop moving when the desired position is reached. The desired adjustment position is as described above, where the bottom of the opening of the collection net box 38 is at the water surface. Then, turn the screw 39 to push the push block 310 into the inside of the mounting hole 37 to form a lock. Then, it can be used to collect and clean the contents of the collection net box 38 that are placed on the inner wall of the pool 1 by centrifugal force during the coagulation process and enter the pool through the opening of the collection net box 38.

[0042] Once the preset amount of material has been collected and cleaned, the collection net box 38 can be indirectly lifted out of the pool body 1 by the push of the electric push rod 32 and raised to the required height, so that the collected flocculent material inside can be taken out.

[0043] 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.
