Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sewage treatment, and particularly relates to a device for strengthening hard removal in a reclaimed water plant. BACKGROUND

[0002] With the increasingly prominent problem of water resource shortage, the importance of reclaimed water as the second water source is increasingly significant. Reclaimed water is water resource that can be reused after sewage treatment and reaching a certain water quality standard, and is widely used in industrial cooling, municipal greening, agricultural irrigation and other fields. In small-scale reclaimed water treatment scenarios (such as community water treatment stations, small-scale industrial circulating water reuse systems and the like), the hard removal treatment of reclaimed water is a key link to guarantee water quality standard and avoid pipeline and equipment scaling. Such scenarios usually have the characteristics of small water treatment capacity, limited equipment installation space, and less human labor investment. At present, the commonly used reclaimed water hard removal device is mostly based on the chemical precipitation principle, and the hard removal device is mixed with hard removal agents (such as sodium carbonate, calcium hydroxide and the like) to make calcium and magnesium ions generate precipitates, and then the water quality is softened through precipitation separation. However, the traditional hard removal device still has the following problems in actual application:

[0003] On the one hand, the mixing, precipitation and sludge discharge system of the traditional hard removal device is mostly designed in a split type, and the mixing tank and the precipitation tank are placed independently, which needs to be connected by an additional pipeline. This not only increases the installation space requirement, but also may cause waste of agents or blockage of precipitates due to the residual pipeline. For small-scale scenarios with limited space, such a decentralized layout is difficult to adapt. On the other hand, the traditional hard removal device usually adopts manual regular dredging, which needs to be frequently stopped and opened, and has high labor intensity and time and labor consuming.

[0064] The clear liquid extraction pipe 8 is connected with the external water pump through a hose, and the height of the bottom end of the clear liquid extraction pipe 8 in the sedimentation tank 1 can be adjusted by pushing and pulling the clear liquid extraction pipe 8, so that the upper layer of water can be extracted according to the height position of the upper layer of water after sedimentation.

[0065] The electric cylinder 411 is started, and the electric cylinder 411 drives the lifting frame 412 to move upward. At this time, the first guide wheel 416 drives the sliding block 417 to slide in the transverse sliding slot hole 413 under the guidance of the lifting frame 412, so that the sliding block 417 slides from one end to the other end of the transverse sliding slot hole 413, and the sliding block 417 drives the fixed frame 415 to make the sliding sleeve 418 move synchronously in the transverse direction. In the process of moving of the sliding sleeve 418, the vertical fixed rod 419 is driven to move along the horizontal guide groove 422, so that the second guide wheel 435 of the telescopic part 43 moves along the horizontal guide groove 422 to the inclined guide groove 423. In the process of moving of the second guide wheel 435 along the horizontal guide groove 422, the mud pushing plate 414 keeps moving and adhering to the inner bottom of the sediment tank 1, pushes the sediment deposited on the inner bottom of the sediment tank 1 to the sewage discharge inlet 512, and the sediment enters the collecting drum 521 through the sewage discharge inlet 512 and the sewage inlet 522. At this time, the second guide wheel 435 enters the inclined guide groove 423 and is located above the guide step 424. When the second guide wheel 435 moves in the horizontal guide groove 422, the second spring 436 is in a compressed state. When the second guide wheel 435 enters the inclined guide groove 423 and is located above the guide step 424, since the depth of the inclined guide groove 423 at this position is greater than the depth of the horizontal guide groove 422, the elastic potential energy of the second spring 436 is released. At this time, the first guide wheel 416 just enters the top end of the first vertical guide long hole 4122 from the first inclined guide long hole 4121, and at the same time, the horizontal eccentric column 606 just enters the top end of the second inclined guide long hole 608 from the second vertical guide long hole 607.

[0066] Subsequently, the telescopic end of the electric cylinder 411 continues to extend, the lifting frame 412 continues to move upward, and the first guide wheel 416 stops moving in the transverse direction and keeps in the first vertical guide long hole 4122, so that the mud pushing plate 414 keeps in the current position and does not move any more. At the same time, under the guidance of the second inclined guide long hole 608, the horizontal eccentric column 606 is driven to move (refer to Figure 6, the horizontal eccentric column 606 drives the connecting rod 605 to rotate the horizontal rotating shaft 601, the horizontal rotating shaft 601 drives the sealing plate 602 and the driving synchronous pulley 603 to rotate synchronously, so that the sealing plate 602 is adjusted from the horizontal state to the vertical state, the driving synchronous pulley 603 rotates 90°, at this time, the sealing plate 602 no longer blocks the drain port 9, the mixed liquid of the mixed medicine and water in the mixing box 2 enters the sedimentation tank 1 through the square tube 3, and the final mixed liquid liquid level is below the horizontal sliding slot hole 413, the driving synchronous pulley 603 drives the driven synchronous pulley 524 to rotate through the synchronous belt, and since the diameter ratio of the driving synchronous pulley 603 and the driven synchronous pulley 524 is 2:1, when the driving synchronous pulley 603 rotates 90°, the driven synchronous pulley 524 rotates 180°, the driven synchronous pulley 524 drives the connecting shaft 523 to rotate the collecting rotating drum 521 by 180°, and the waste inlet 522 is adjusted from the upward state to the downward state, at this time, the waste inlet 522 is just opposite to the waste outlet 513, and then the collected sediments in the collecting rotating drum 521 are discharged through the waste inlet 522 and the waste outlet 513.

[0067] When the mixed liquid in the mixing box 2 flows into the sedimentation tank 1, the extension end of the electric cylinder 411 is retracted, the lifting frame 412 moves downward, the horizontal eccentric column 606 is guided by the second inclined guide long hole 608, the horizontal rotating shaft 601 rotates reversely by 90°, and the sealing plate 602 is reset to the horizontal state to block the drain port 9.

[0068] Meanwhile, the first guide wheel 416 enters the first inclined guide long hole 4121 from the first vertical guide long hole 4122 during the downward movement of the lifting frame 412, under the guidance of the first inclined guide long hole 4121, the second guide wheel 435 moves from the low part of the inclined guide groove 423 to the high part of the inclined guide groove 423, and under the guidance of the guide step 424, the second guide wheel 435 can only move along the inclined guide groove 423 during the return process. When the second guide wheel 435 moves along the inclined guide groove 423, the second guide wheel 435 moves while driving the inner sleeve 434, the outer sleeve 433 and the vertical fixed rod 419 to move upward, the vertical fixed rod 419 drives the sliding ring 431 to slide upward when moving upward, and the first spring 432 is elastically compressed, thereby making the mud pushing plate 414 move upward, and during the return process, the mud pushing plate 414 moves to above the inner side bottom surface of the sediment tank 1, preventing the sediment from being pushed by the mud pushing plate 414 to the side opposite to the sewage inlet 512, thereby preventing part of the sediment from being pushed out, when the second guide wheel 435 enters the vertical guide groove 421 from the inclined guide groove 423, the elastic potential energy of the first spring 432 is released, thereby pushing the sliding ring 431 to make the vertical fixed rod 419 move downward, the second guide wheel 435 enters the horizontal guide groove 422 from the vertical guide groove 421 again, and the mud pushing plate 414 is attached to the inner side bottom of the sediment tank 1 again, preparing for the next sewage.

[0069] At this time, the blocking plate 602 keeps the drainage port 9 blocked, and the next stirring and mixing of water and water hardness removing agent can be performed. At this time, the water just discharged into the sediment tank 1 can be just precipitated.

[0070] The above is only an embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
