Description

Technical Field

[0001] The utility model belongs to the technical field of titanium plate production and processing, and particularly relates to a purification treatment device for cleaning waste water after hot-rolled titanium plates are pickled. Background Art

[0002] Pickling is an essential part of titanium plate production and processing; the main function of the pickling section is to remove impurities such as oxide scale produced on the surface of the titanium plate after annealing, so the pickling wastewater will contain a large amount of oxide slag; at the same time, after pickling, the titanium plate will also undergo cleaning and drying processes, and the wastewater produced by cleaning will also contain acid and oxidized impurities residues; therefore, the wastewater produced by cleaning or cleaning the titanium plate needs to be treated when discharged, and direct discharge without treatment will cause greater environmental pollution;

[0003] After searching, the prior art publication number is CN 112811674 A, which is a neutralization treatment device for pickling wastewater of hot-rolled nickel-based alloy stainless steel medium and thick plates; it includes a purification tank, a cleaning plate, a reciprocating screw, a sliding plate and an air intake pipe; in the utility model, the reciprocating screw is threadedly connected to the fixed block, so that the sliding plate can move back and forth in the slide groove inside the horizontal track during the process of the reciprocating screw driven by the driving motor to rotate, and the lime inside the feed bin can be evenly sprinkled into the purification tank, thereby improving the neutralization effect of the lime on the acidic substances inside the purification tank; however, in comparison, there are application disadvantages when the filter barrel provided therein filters wastewater. First, although the cleaning plate and the brush are provided therein to clean the filter plate, the filter holes on the filter plate will still be blocked after long-term accumulation. Secondly, it is difficult to clean the filter plate again when it is seriously blocked, and it is also relatively difficult to replace the filter plate in this technology, which will greatly affect the treatment process of the subsequent process; in addition, the wastewater also has the disadvantage of flowing away with the collection tank;

[0004] After searching, it was found that a cold-rolled stainless steel annealing and pickling line wastewater treatment system with a prior art announcement number of CN 218404415 U is also suitable for cleaning and purifying the cleaning wastewater of the hot-rolled stainless steel annealing and pickling line; the system comprises a treatment box, wherein the treatment box is provided with a filter chamber, an aeration chamber, a flocculation chamber and an acid adding chamber which are interconnected; during operation, the pickling wastewater enters the filter chamber through the liquid inlet, and the large particles of impurities in the pickling wastewater can be retained in the filter chamber through the filtering effect of the filter chamber, and the filtered sewage enters the aeration chamber, and oxygen is transported through the aerator to convert the iron and manganese ions in the sewage into high-valent oxides and hydroxides, and the sewage enters the flocculation chamber for flocculation treatment; wherein the filtering process is completed through the filter chamber in the filter chamber; since the wastewater contains more impurities, the filter chamber is easily blocked, and there is no technical means for clearing the filter chamber in the technical solution, so it will affect the subsequent treatment process and process after the blockage occurs and cannot be cleared in time, thereby reducing the treatment efficiency and effect of the wastewater;

[0005] In view of the above problems, the present utility model provides a purification treatment device and method for cleaning wastewater after pickling, which can timely replace the filter plate during the continuous and uninterrupted filtration of wastewater, ensure the filtration effect, and thus ensure the normal progress of the subsequent cleaning process. Summary of the Utility Model

[0006] The purpose of the present utility model is to overcome the deficiencies in the prior art and provide a purification treatment device for cleaning wastewater after pickling of hot-rolled titanium plates. The filtering mechanism can alternately use and timely replace the filter plates to ensure the normal progress of the filtering process, and thus ensure the normal progress of the subsequent treatment process. At the same time, a roller and a neutralization tank are provided in the neutralization mechanism. First, the neutralizing agent is mixed in the roller, and then the wastewater in the roller is used as the source of the neutralizing agent to stir and neutralize the wastewater in the neutralization tank. The conventional mixing method of adding the neutralizing agent from the top of the tank and stirring is changed to the mixing method of the wastewater in the roller in the neutralization tank and the wastewater outside the roller, which greatly improves the mixing and stirring efficiency, and thus improves the neutralization efficiency.

[0007] In order to achieve the above purpose, the technical solution adopted by the present utility model is:

[0012] Stirring blades are provided on the first stirring shaft shown.

[0013] A rotating shaft is provided inside the roller. The rotating shaft is hollow. A second through port is provided at the top end of the rotating shaft, and the second through port is arranged inside the through pipe and is interconnected. Spray nozzles are provided on the rotating shaft, and two sections of reciprocating threads are provided on the outer wall of the rotating shaft. A chute is provided on the inner wall of the roller.

An inclined angle is provided at the opening to expand the rotation angle of the sector plate.

[0014] Inside the roller, there are a pair of second stirring shafts and a pair of stirring frames; the stirring frames are arranged on the reciprocating thread section and are connected to the rotating shaft through threads. The stirring frames include fixed frames, on which there are sliders arranged in chutes, and stirring blades are rotatably connected inside the fixed frames; at the bottom end of the main shaft, there is a first motor providing power for it, and the first motor is fixed to the bottom of the neutralization tank through a motor base; the first motor drives the main shaft to rotate, and then drives the roller and the first stirring shaft to rotate around the main shaft as the axis.

[0015] There is also a second gear ring inside the neutralization tank and it is fixedly connected to the inner wall of the neutralization tank; at the top end of the first stirring shaft, there is a gear meshing with the second gear ring; at the top end of the rotating shaft, there is a gear meshing with the second gear ring.

[0016] There is a first gear ring on the through pipe; at the top end of the second stirring shaft, there is a gear meshing with the first gear ring.

[0017] At the bottom of the sedimentation tank, there is a dirt removal port. On one side of the sedimentation tank, there is a support frame for supporting and fixing the pipeline, and on the other side, there is a first drain pipe and a support frame for supporting and fixing it; there is a first water pump on the first drain pipe; one end of the first drain pipe is provided with a telescopic pipe capable of adjusting the depth of insertion into the sedimentation tank.

[0018] On the side wall of the filter box, there is a transparent observation port, which is convenient for observing the accumulation of filtered impurities on the filter plate inside the filter box.

[0019] The beneficial effects of the present utility model compared with the prior art are as follows:

[0020] 1) There is a filtering mechanism capable of continuously filtering the cleaning wastewater; firstly, there are a pair of filter plates symmetrically arranged on both sides of the partition and cooperating with a rotatable guide plate. After the guide plate rotates to change the flow direction, the filter plates can be used alternately and replaced, and when replacing the filter plates, it can also ensure that the cleaning wastewater can be continuously filtered;

[0021] Secondly, when replacing the filter plate, after opening the replacement port, just rotate the adjusting rod to make the first gear and the first gear rotate, and then drive the top plate to rotate, so that the top plate rotates to the horizontal and the hook plate and the hook block are disengaged from each other's hooked state. Then, under the push of the third spring, the top block quickly pushes the filter plate out of the replacement port by a certain distance, which helps to collect the filter plate and avoids the drawback that the filter plate cannot be quickly removed when it is completely inside the filter box;

[0022] When installing a new filter plate, just insert the filter plate into the filter box along the slide rail, so that the filter plate pushes the top plate, and the top plate is reset and pushed back into the hook plate. Then rotate the adjusting rod to make the top plate rotate, and the hook plate hooks the hook block again; then the sealing plate is inserted to close the replacement port to complete the replacement of the filter plate. This method is fast and convenient, greatly improving the replacement efficiency;

[0023] 2) Inside the neutralization mechanism, there are a main shaft, a roller, and a first stirring shaft. Inside the roller, there are a rotating shaft, a second stirring shaft, and a stirring frame. The neutralizing agent can be ejected from the nozzles on the rotating shaft through the third water pump. Since the nozzles are provided on the rotating shaft body, the neutralizing agent can be transmitted to the upper, middle, and lower layers of the roller in the first time, achieving relatively uniform fixed-point dosing. Then, through the revolution and rotation of the rotating shaft and the mixing of the second stirring shaft and the stirring frame, the wastewater and the neutralizing agent in the roller can be quickly stirred and mixed. Relative to the wastewater outside the roller, a relatively large source of the neutralizing agent can be formed.

[0024] Further, when the main shaft rotates in reverse, the sealing plate will be rotated by the fan plate to open the opening on the roller, so that the uniformly mixed wastewater in the roller flows out and is mixed and neutralized again with the wastewater outside the roller. Compared with the conventional method of one-time dosing of the neutralizing agent, in the present utility model, the wastewater in the roller is first stirred and neutralized, and then the wastewater in the roller is used as the neutralization source to be stirred and neutralized again with the wastewater outside the roller. In comparison, the source of the agent is relatively expanded, and it can be quickly distributed in the wastewater at different levels in the neutralization tank, improving the stirring and making the neutralization efficiency more uniform.

[0050] A treatment method for a purification treatment device for cleaning waste water after pickling of hot-rolled titanium plates is as follows:

[0051] 1) Transmission of clean waste water: The clean waste water is first transmitted through the water inlet pipe 5 into the filter box 404 of the filter mechanism 4; then the clean waste water is guided by the guide plate 42 and then flows through the filter plate 6 for filtration; when there are many impurities on the filter plate 6, the second motor 43 drives the guide plate 42 to rotate to the other side, changing the flow direction of the clean waste water so that it flows through the filter plate 6 on the other side; the flow direction of the clean waste water is changed by rotating the guide plate 42, thereby realizing the effect of alternating use of the filter plate 6, so as to achieve the effect of continuous filtration of the clean waste water.

[0052] 2) Rapid replacement of filter plates: observe the accumulation of impurities on the filter plate 6 inside the filter box 404 through the observation port 405. When the filter plate 6 filters a lot of impurities, it can be quickly replaced. First, pull out the sealing plate to open the replacement port 402; then rotate the adjustment rod 44 to drive the second gear 46 and the shaft sleeve 461 to rotate, thereby driving the spline shaft 451 and the top plate 45 to rotate, so that the hook block 452 is separated from the hooking state between the hook plate 411, and then pushed out by the third spring 47, and then enter. The filter plate 6 is pushed out of the replacement port 402 for a distance under the push of the top plate, so as to facilitate the collection of the filter plate 6; when installing the filter plate, it is pushed into the filter box 404 along the replacement port 402 and the slide rail 403, and the top plate 45 is pushed back to the side of the hook plate 411, and then the adjusting rod 44 is rotated to rotate the spline shaft 451 and the top plate 45, so that the hook plate 411 and the hook block 452 are hooked and limited to each other, preventing the top plate 45 from being pushed out by the third spring 47; and then the sealing plate is inserted to block the replacement port 402.

[0053] 3) Neutralization of cleaned wastewater: After cleaning, the wastewater is transferred to the neutralization tank 32 through the second drainage pipe 401 for neutralization;

[0054] S1: The neutralizing agent in the agent tank 31 is supplied to the main shaft 33 through the action of the third water pump 331. The neutralizing agent passes through the main shaft 33, the through pipe 332, and the rotating shaft 343 in sequence, and then is sprayed out through the nozzle 3432. The third water pump 331 provides power to spray the neutralizing agent along the nozzle 3432; then the main shaft 33 is driven to rotate by the first motor 37, and then the roller 34 and the second stirring shaft 39 are driven to rotate with the main shaft 33 as the axis; the roller 34 and the second stirring shaft 39 are caused to rotate by the arrangement of the first gear ring 3322 and the second gear ring 35; at this time, the fan plate 3421 is subjected to the resistance of the water flow so that the sealing plate 342 closes the opening 341 on the roller 34, so that the neutralizing agent is first mixed with the wastewater in the roller 34; at the same time, the stirring frame 38 reciprocates up and down along the slider 382 to improve the mixing efficiency.

[0055] S2: After the roller 34 rotates as required and finishes, the first motor 37 drives it to reverse. The fan plate 3421 rotates under the resistance of the water flow to open the opening on the roller 34, so that the uniformly mixed neutralizing agent and wastewater in the roller 34 flow out along the opening 341 and enter the neutralizing tank 32 to mix with the wastewater as a whole.

[0056] According to the tooth ratio setting of the first gear ring 3322 and the second gear ring 35, the rotation speed ratio of the roller 34 to the second stirring shaft 39 is 1:3; further, the rotation speed of the main shaft 33 is set to 45 - 60 r / min; the mixing time is 25 - 35 min, and then the pH value is detected by sampling through the sampling port 310; it is determined whether the neutralization effect is satisfied. If not, continue mixing or add the agent. If satisfied, transfer the wastewater to the sedimentation tank 1.

[0057] 4) Transfer and precipitation of neutralized wastewater: The wastewater mixed with the neutralizing agent flows into the sedimentation tank 1 through the pipeline 2 and then stands for precipitation; the supernatant of the neutralized wastewater after precipitation is discharged through the first drain pipe 13, and the impurities after precipitation are discharged and cleaned through the dirt removal port 11; the precipitation time is set to 45 - 70 min.
