[0021] The utility model will be described below in detail with reference to the drawings and in combination with embodiments.

[0022] Please refer to Figures 1-3 A coagulation sedimentation tank for treating water-based ink wastewater and pickling phosphating wastewater, comprising a coagulation sedimentation tank 10, a plurality of coagulation sedimentation tanks 11 are formed in the inside of the coagulation sedimentation tank 10 by a plurality of partition plates, a group of lump collecting mesh plates 13 are arranged in the coagulation sedimentation tanks 11 in a lifting manner, a group of stirring mesh plates 14 are supported in contact on the upper side of the lump collecting mesh plates 13 through a plurality of evenly distributed lifting columns 27, the stirring mesh plates 14 are controlled to move up and down through the lifting columns 27, so that the waste liquid in the coagulation sedimentation tanks 11 is mixed and stirred, a plurality of evenly distributed positioning sliding blocks 33 are symmetrically installed on the two sides of the lump collecting mesh plates 13, a positioning sliding groove 32 is formed in the inner wall of the coagulation sedimentation tank 11 corresponding to the end of one of the positioning sliding blocks 33, the positioning sliding block 33 moves up and down along the inside of the positioning sliding groove 32, a longitudinal slide 19 is formed in the inner wall of the coagulation sedimentation tank 11 corresponding to the other positioning sliding block 33, the positioning sliding block 33 extends through the longitudinal slide 19 to connect with a lifting piece in the inner wall of the coagulation sedimentation tank 11, the lifting piece controls the positioning sliding block 33 to drive the lump collecting mesh plates 13 and the stirring mesh plates 14 to move up and down, so as to realize the full mixing of the waste liquid in the coagulation sedimentation tanks 11 and the rapid transfer and output of the coagulation lumps after mixing, which greatly improves the operation efficiency of the sedimentation tank to a certain extent.

[0023] In the embodiments of the present application, the lump collecting mesh plates 13 and the stirring mesh plates 14 have the same area and are slightly smaller than the size of the inner bottom wall of the coagulation sedimentation tanks 11, which facilitates the falling of the waste liquid on the upper side of the lump collecting mesh plates 13 along the edge part during the lifting of the lump collecting mesh plates 13. The main reason for this is that the lump collecting mesh plates 13 are designed in a mesh structure, and when the waste liquid coagulates, there is a situation that some mesh holes of the lump collecting mesh plates 13 are blocked. In order to keep the coagulation lumps under the premise of containing liquid in the coagulation sedimentation tanks 11, they are output upward. By making the area of the lump collecting mesh plates 13 smaller than the bottom of the coagulation sedimentation tanks 11, part of the coagulation lumps will be left in the bottom of the coagulation sedimentation tanks 11, but compared with the output coagulation lumps, the remaining part is within an acceptable range.

[0024] Please refer to Figure 5 , Figure 7The top of the stirring net plate 14 is uniformly provided with a plurality of stirring columns 29, the circumferential outer wall of the stirring column 29 is rotatably connected with a plurality of radially distributed rotating rods 30, the rotating rod 30 is axially perpendicular to the stirring column 29, the outer side of the rotating rod 30 is uniformly provided with a plurality of stirring blades 31, that is, when the stirring net plate 14 moves up and down, the stirring column 29 is driven to move simultaneously, and the rotation connection between the rotating rod 30 and the stirring column 29 is used to control the rotation of the stirring blade 31, so as to stir and mix the waste liquid;

[0025] Specifically, the diameter of the lump collecting net plate 13 is much smaller than the size of the condensed lump, that is, the condensed lump is stably and fully collected and transferred, and at the same time in the mixing and condensing process, the bottom of the lump collecting net plate 13 is in contact with the inner bottom wall of the coagulation and precipitation tank 11, so that the condensed lump generated during the condensation process of the two waste liquids is deposited on the lump collecting net plate 13, and then the lump collecting net plate 13 is lifted to quickly transfer and output the condensed lump.

[0026] In one example of the present application, the lifting member comprises a screw rod 25 vertically arranged in the inner wall of the coagulation and precipitation tank 11, a nut 26 threadedly connected to the screw rod 25, a guide device arranged on the nut 26 for limiting the rotation of the nut 26, the bottom end of the screw rod 25 is rotatably connected in the inner wall of the coagulation and precipitation tank 11, and the top end is connected with a gear driving member, under the action of the gear driving member, the rotation of the screw rod 25 is controlled, and in turn the nut 26 is driven to move up and down, and the positioning sliding block 33 is lifted and lowered;

[0027] Referring to Figure 4 , Figure 6 The outer side of the gear driving member is provided with a group of gear housings 18, the gear driving member comprises a bevel gear two 24 fixed on the top end of the screw rod 25, one side of the bevel gear two 24 is vertically engaged with a bevel gear one 23, one side of the bevel gear one 23 is connected with a driven tooth 17, the coagulation and precipitation tank 11 is provided with an opening corresponding to the driven tooth 17 on the top, the top half of the driven tooth 17 is arranged outside the coagulation and precipitation tank 11, a group of driving teeth 16 are arranged on the outer side of the driven tooth 17, which move along the top of the coagulation and precipitation tank 11, by moving the driving teeth 16, the corresponding driven tooth 17 is engaged with the driving teeth 16 on the top side, so as to control the up and down movement of the lump collecting net plate 13 in the corresponding coagulation and precipitation tank 11, one side of the driving tooth 16 is connected with a servo motor 15, the outer side of the servo motor 15 is provided with a motor shell, two groups of electric wheels 21 are symmetrically and rollably connected on the bottom sides of the motor shell, the electric wheels 21 are arranged in the wheel rails 22 on the top wall of the coagulation and precipitation tank 10 and are in a positioning state in the transverse direction, that is, the electric wheels 21 are kept rolling in the wheel rails 22 while being kept vertical, so as to stably support and transfer the motor shell, thereby realizing the function of lifting and transferring the lump collecting net plate 13 in the coagulation and precipitation tank 11 by moving a single servo motor 15.

[0028] As a preferred embodiment of the present application, it should be noted that some structures, tools, etc. used in the technical solution are made of corrosion-resistant materials to ensure safe and smooth operation when in contact with acidic and alkaline waste liquid inside the coagulation sedimentation tank 11.

[0029] As a preferred embodiment of the present application, since the longitudinal slide 19 and the positioning chute 32 are both provided on the inner wall of the coagulation sedimentation tank 11 and are in communication with the inside of the coagulation sedimentation tank 11, the waste liquid inside the coagulation sedimentation tank 11 can seep into the longitudinal slide 19 and the positioning chute 32 during use, but under the strong driving of the lifting member, the corresponding components can still operate normally.

[0030] The working principle of the present application is as follows: all the driving members, i.e. power elements, electrical components and compatible power sources are connected by wires at the idle place of the device. The electrical components are sequentially connected in working order, and the detailed connection means are known in the art. The working principle and process are mainly introduced below, and the electrical control is not described. During operation, the acid pickling and phosphating wastewater to be mixed and precipitated is mixed with the water-based ink wastewater. At this time, the lifting column 27 is started to move up and down, driving the stirring column 29, the rotating rod 30 and the stirring blade 31 to stir the mixed liquid inside the coagulation sedimentation tank 11, so that it is fully mixed and coagulated. The coagulation produced by the coagulation is placed on the coagulation collection screen 13 under the action of gravity. After coagulation is completed, the electric wheel 21 is started to drive the driving gear 16 to move to the driven gear 17 on the side of the coagulation sedimentation tank 11, driving the driven gear 17 to rotate. Then, under the connection of the bevel gear one 23 and the bevel gear two 24, the lead screw 25 is controlled to rotate, and the nut 26 is controlled to drive the coagulation collection screen 13 to rise. At this time, the waste liquid on the coagulation collection screen 13 flows out through the holes or the gaps on both sides, and the coagulation block on the coagulation collection screen 13 is moved upward.

[0031] The preferred embodiments of the present application have been described in detail above, but the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present application.
