Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a neutralization device for treating stainless steel pickling wastewater. Background Technology

[0002] The pickling process of the stainless steel annealing and pickling production line requires the use of a large amount of acid solutions such as sulfuric acid, hydrochloric acid, nitric acid, and hydrofluoric acid to clean the surface of the stainless steel strip. After pickling, a lot of pickling wastewater is generated, which needs to be treated before it can be discharged. When treating stainless steel pickling wastewater through neutralization, alkaline neutralizing agents such as limestone are typically added. A stirring device is used to agitate the wastewater, ensuring thorough mixing of the wastewater and the agent to complete the neutralization process and facilitate subsequent sedimentation. However, the reaction between the alkaline neutralizing agent and the wastewater generates numerous bubbles. During agitation, these rising bubbles easily carry reactants from the wastewater, causing them to adhere to the inner wall of the neutralization tank and form a hard scale layer. This results in localized eddies and backflow at the scale protrusions when the agitator rotates the wastewater, reducing the flow velocity near the tank wall and hindering the thorough diffusion and mixing of the agent, thus lowering the neutralization efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a neutralization device for treating stainless steel pickling wastewater, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a neutralization device for treating stainless steel pickling wastewater, comprising a main body, an internal neutralization chamber, sliding grooves on the left and right inner walls of the neutralization chamber, a plurality of sludge discharge pipes fixedly connected to the front of the main body, and connecting pipes fixedly connected to the left and right sides of the main body, and further comprising: A sliding mechanism is installed inside the neutralization chamber to mix and react wastewater with neutralizing agents. The sliding mechanism includes a central disk 1 set inside the neutralization chamber, and a number of perforated plates are fixedly connected to the outer surface of the central disk 1. The number of perforated plates are set at an angle. An auxiliary mechanism is installed at the bottom of the central disk one and is used to push the central disk one to slide up and down. The auxiliary mechanism includes a notched plate fixedly connected to the bottom of the central plate, and the notched plate is eccentrically positioned relative to the central plate.

[0005] Furthermore, the main body includes: The stirring assembly is located inside the neutralization chamber and is used to stir the wastewater.

[0006] Furthermore, the sliding mechanism also includes: A connecting assembly is installed on the sidewall of several perforated plates; The guide component is installed on the side wall of the connecting component and is used to guide wastewater to flush the inner wall of the neutralization tank.

[0007] Furthermore, the auxiliary mechanisms also include: The push component is installed at the bottom of the notch plate; The elastic component is installed on the side wall of the push component.

[0008] Furthermore, the stirring assembly includes a fixed frame fixedly connected inside the neutralization chamber, and a drive motor is fixedly connected to the top of the fixed frame; A stirring shaft is fixedly connected to the output end of the drive motor, and a polygonal frame is fixedly connected to the outer surface of the stirring shaft. The rotation of the stirring shaft can drive the central disk to rotate through the polygonal frame.

[0009] Furthermore, the central disc is slidably connected to the outer surface of the polygonal frame; The connecting assembly includes a fixing ring that is fixedly connected to one end of several perforated plates away from the central disk, and the side wall of the fixing ring has several through-hole grooves.

[0010] Furthermore, the guide assembly includes several tilting frames fixedly connected to the outer surface of the fixing ring; Among them, several inclined plates are fixedly connected to the top and bottom of the fixing ring; The inclined frame can capture wastewater as the fixed ring rotates, allowing the wastewater to quickly enter the through-hole groove. As the wastewater enters the through-hole groove, it will quickly flush the inner wall of the neutralization chamber under the guidance of the inclined plate's inner wall as the fixed ring rotates.

[0011] Furthermore, the actuating component includes a second central disk rotatably connected to the outer surface of the stirring shaft, and two positioning rods are fixedly connected to the top of the second central disk; A spring telescopic cylinder is fixedly connected to the bottom of the second central plate, and a central rod is fixedly connected to the inner top wall of the spring telescopic cylinder. Among them, the notched plate is eccentrically positioned between the top of the second central plate and the second central plate; The telescopic end of the spring telescopic cylinder is hollow, and the telescopic edge of the spring telescopic cylinder can slide up and down on the outer surface of the central rod.

[0012] Furthermore, the resilient component includes a support frame that is slidably connected between the two sliding slots; A semi-circular plate is fixedly connected to the top of the support frame, and the top of the support frame is in contact with the bottom of the spring telescopic cylinder.

[0013] Furthermore, a second semicircular plate is slidably connected to the side wall of the first semicircular plate, and an elastic frame is fixedly connected to the side wall of the spring telescopic cylinder. The bottom of the elastic frame is fixedly connected to the top of the support frame, and several elastic plates are fixedly connected to the inner wall of the bottom of the elastic frame. The elastic plate is set to an inclined state. When the notched plate drives the positioning rod on the second central plate to rotate, the second central plate will drive the spring telescopic cylinder and the central rod to rotate synchronously. When the spring telescopic cylinder rotates, it will enter the top plane of the semicircular plate one along the inclined surface. When the spring telescopic cylinder slides to the top plane of the semicircular plate one, the bottom of the central rod will be suspended. Thus, when the first central plate rotates, it can move up and down through the elasticity of the second central plate and the spring telescopic cylinder.

[0014] The present invention has the following beneficial effects: 1. The present invention, when guided by the inclined frame to continuously flush the inner wall of the neutralization chamber at a relatively fast speed, can reduce the deposition and adhesion of impurities carried by air bubbles on the inner wall of the neutralization chamber. At the same time, by relying on the up and down sliding of the fixed ring, the spray area of ​​the wastewater can be dynamically changed, avoiding the formation of hard scale layer, ensuring sufficient diffusion of the agent and mixing with the wastewater, and improving the neutralization efficiency of the wastewater.

[0015] 2. In this invention, the fixed ring moves up and down through contact with the two positioning rods on the central disc and the elasticity of the spring telescopic cylinder. At this time, the fixed ring slides back and forth on the surface of the stirring shaft through the central disc. When the central disc and the perforated plate drive the fixed ring to slide back and forth, the wastewater is disturbed. The wastewater will surge under the sliding of multiple perforated plates. By surging the wastewater, the phenomenon of bubbles gathering towards the center of the water after being washed by the edge of the neutralization chamber wall and foam covering the liquid surface can be reduced. This accelerates the uniformity of the agent being added to and mixed in the wastewater, and further improves the neutralization treatment efficiency of the wastewater.

[0016] 3. By slowing down the rotational speed of the spring telescopic cylinder driven by the second central disc, this invention can reduce the situation where the second central disc, driven by the rotational inertia, causes the spring telescopic cylinder to detach from the top of the semicircular plate too quickly when the notched disc pushes the second central disc to rotate via the positioning rod. This improves the stability of the second central disc driving the first central disc during lifting and reciprocating vibration.

[0017] 4. This invention, by disturbing the wastewater and combining it with the reciprocating sliding of the second central plate, can reduce the excessive deposition of impurities in the wastewater between the support frame and the first central plate due to the excessively stable wastewater flow rate. By reducing the deposition of impurities in this area, the continuity and stability of the operation of the sliding mechanism and auxiliary mechanism in this area can be ensured, the frequency of subsequent maintenance in this area can be reduced, and the neutralization efficiency of fully mixing the wastewater can be further enhanced.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-9 As shown, this invention is a neutralization device for treating stainless steel pickling wastewater, comprising a main body 1, a neutralization chamber inside the main body 1, sliding grooves 101 on the left and right inner walls of the neutralization chamber, a plurality of sludge discharge pipes fixedly connected to the front of the main body 1, and connecting pipes fixedly connected to the left and right sides of the main body 1, and further comprising: Sliding mechanism 2 is installed inside the neutralization chamber and is used to mix and react wastewater with neutralizing agent; The sliding mechanism 2 includes a central disk 201 disposed inside the neutralization chamber. Several perforated plates 211 are fixedly connected to the outer surface of the central disk 201. The several perforated plates 211 are arranged at an inclination. Auxiliary mechanism 3 is installed at the bottom of central disk 201 and is used to push central disk 201 to slide up and down; The auxiliary mechanism 3 includes a notched plate 301 fixedly connected to the bottom of the central plate 201, and the notched plate 301 and the central plate 201 are eccentrically positioned.

[0023] Entity 1 includes: A stirring assembly 11 is installed inside the neutralization chamber and is used to stir the wastewater.

[0024] The sliding mechanism 2 also includes: Connecting component 21 is installed on the sidewall of a plurality of perforated plates 211; The guide component 22 is installed on the side wall of the connecting component 21 and is used to guide the wastewater to flush the inner wall of the neutralization chamber.

[0025] Auxiliary mechanism 3 also includes: Push component 31 is installed at the bottom of notch plate 301; The elastic component 32 is installed on the side wall of the push component 31.

[0026] The stirring assembly 11 includes a fixed frame 111 fixedly connected inside the neutralization chamber, and a drive motor 112 fixedly connected to the top of the fixed frame 111. A stirring shaft 113 is fixedly connected to the output end of the drive motor 112, and a polygonal frame is fixedly connected to the outer surface of the stirring shaft 113. like Figure 4 As shown in position G, the rotation of the stirring shaft 113 can drive the central disk 201 to rotate through the polygonal frame.

[0027] The central disc 201 is slidably connected to the outer surface of the polygon frame; The connecting component 21 includes a fixing ring 212 fixedly connected to one end of several perforated plates 211 away from the central disk 201. The side wall of the fixing ring 212 is provided with several through slots 213. When the stirring shaft 113 rotates rapidly in the wastewater, the stirring shaft 113 will drive the central disk 201 and the notched disk 301 to rotate synchronously. When the central disk 201 rotates, it will drive the fixed ring 212 to rotate synchronously through multiple perforated plates 211. When the fixed ring 212 rotates in the wastewater, multiple inclined plates 221 on the outer surface of the fixed ring 212 will capture the wastewater.

[0028] The guide component 22 includes a plurality of inclined frames 222 fixedly connected to the outer surface of the fixing ring 212; Among them, the top and bottom of the fixing ring 212 are fixedly connected with several inclined plates 221; The inclined frame 222 can capture wastewater as the fixed ring 212 rotates, allowing the wastewater to quickly enter the through hole groove 213. When the wastewater enters the through hole groove 213, it will quickly flush the inner wall of the neutralization chamber under the guidance of the inclined inner wall of the inclined plate 221 as the fixed ring 212 rotates.

[0029] The pushing component 31 includes a central disk 311 rotatably connected to the outer surface of the stirring shaft 113, and two positioning rods are fixedly connected to the top of the central disk 311; A spring telescopic cylinder 312 is fixedly connected to the bottom of the center plate 2 311, and a center rod 313 is fixedly connected to the top inner wall of the spring telescopic cylinder 312. Among them, the notch plate 301 is eccentrically positioned between the top of the center plate 2 311 and the center plate 2 311; The telescopic end of the spring telescopic cylinder 312 is hollow, and the telescopic side of the spring telescopic cylinder 312 can slide up and down on the outer surface of the central rod 313; During the rotation of the second central disk 311, the second central disk 311 will drive the spring telescopic cylinder 312 to rotate synchronously. When the spring telescopic cylinder 312 rotates, it will enter the top plane of the first semicircular plate 322 through the inclined surface of the first semicircular plate 322. At this time, the spring telescopic cylinder 312 will push the first central disk 201 to slide upward through the second central disk 311 and the positioning rod.

[0030] The elastic component 32 includes a support frame 321 that is slidably connected between two sliding grooves 101; A semi-circular plate 322 is fixedly connected to the top of the support frame 321, and the top of the support frame 321 is in contact with the bottom of the spring telescopic cylinder 312.

[0031] The side wall of the semicircular plate 322 is slidably connected to the semicircular plate 323, and the side wall of the spring telescopic cylinder 312 is fixedly connected to the elastic frame. The bottom of the elastic frame is fixedly connected to the top of the support frame 321, and several elastic pieces 324 are fixedly connected to the bottom inner wall of the elastic frame. The elastic plate 324 is set to an inclined state. When the notched plate 301 drives the center plate 311 to rotate by pushing the positioning rod on the center plate 311, the center plate 311 will drive the spring telescopic cylinder 312 and the center rod 313 to rotate synchronously. When the spring telescopic cylinder 312 rotates, it will enter the top plane of the semicircular plate 322 along the inclined surface. When the spring telescopic cylinder 312 slides to the top plane of the semicircular plate 322, the bottom of the center rod 313 will be suspended. Thus, when the center plate 201 rotates, it can move up and down through the elasticity of the center plate 311 and the spring telescopic cylinder 312.

[0032] In use, first connect the connecting pipes on the left and right sides of the main body 1 to the external wastewater conveying pipe and wastewater receiving pipe, respectively. At the same time, connect the multiple sludge discharge pipes on the front of the main body 1 to the external sludge pump. Then, the staff put the support frame 321 into the sliding trough 101 and install the fixing frame 111 into the neutralization chamber. When the wastewater needs to be neutralized, start the drive motor 112 to drive the stirring shaft 113 to rotate rapidly. At the same time, the wastewater is transported to the inside of the main body 1 through the wastewater conveying pipe. At this time, the wastewater will be in the neutralization chamber. Then, the neutralizing agent is added to the neutralization chamber. When the stirring shaft 113 rotates, it will drive the wastewater to rotate, so that the wastewater and the neutralizing agent are mixed. After neutralization, the wastewater will settle in the settling area inside the main body 1 and then be transported to the subsequent treatment equipment through the wastewater receiving pipe to complete the neutralization operation of the wastewater.

[0033] Figure 9 Area C is the neutralization chamber, used to neutralize wastewater, and area F is the sedimentation area, used to settle the neutralized wastewater.

[0034] When the stirring shaft 113 rotates rapidly in the wastewater, the stirring shaft 113 will drive the central disk 201 and the notched disk 301 to rotate synchronously. When the central disk 201 rotates, it will drive the fixed ring 212 to rotate synchronously through multiple perforated plates 211. When the fixed ring 212 rotates in the wastewater, multiple inclined plates 221 on the outer surface of the fixed ring 212 will capture the wastewater and guide it into the through-hole groove 213. When the wastewater enters the through-hole groove 213, it will be sprayed at a high speed onto the inner wall of the neutralization chamber under the guidance of the inclined frames 222 on both sides of the fixed ring 212 as the fixed ring 212 rotates. When the central disk 201 drives the notched disk 301 to rotate in the wastewater, since the notched disk 301 and the central disk 211 are eccentrically set, when the notched disk 301 rotates, the notch on the side wall of the notched disk 301 will push one of the positioning rods, causing the central disk 211 to rotate about 180 degrees and then separate from the positioning rod. During the rotation of the central disk 211, the central disk 211 will drive the spring telescopic cylinder 312 to rotate synchronously. When the spring telescopic cylinder 312 rotates, it will enter the top plane of the semicircular plate 322 through the inclined surface of the semicircular plate 322. At this time, the spring telescopic cylinder 312 will push the central disk 201 to slide upward through the central disk 211 and the positioning rod. When one of the positioning rods separates from the notch of the notched disk 301, and the other positioning rod does not contact the notch of the notched disk 301, the fixing ring 212 will maintain the raised position and change the flushing position of the wastewater through the guide frame 222 to the neutralization chamber. When the notch plate 301 continues to rotate about 180 degrees, the notch on the notch plate 301 will contact another positioning rod and drive the central plate 311 and the spring telescopic cylinder 312 to rotate synchronously with the rotation of the notch plate 301. At this time, the spring telescopic cylinder 312 will separate from the semicircular plate 322, and the fixed ring 212 will slide down to reset through the rotation of the inclined perforated plate 211 in the wastewater. This reciprocating motion allows the fixed ring 212 to slide up and down while rotating in the wastewater. When guided by the inclined frame 222 to continuously flush the inner wall of the neutralization chamber at a relatively fast speed, it can reduce the deposition and adhesion of impurities carried by air bubbles on the inner wall of the neutralization chamber. At the same time, by relying on the up and down sliding of the fixed ring 212, the spray area of ​​the wastewater can be dynamically changed to avoid the formation of hard scale layer, ensure the sufficient diffusion of the agent and mixing with the wastewater, and improve the neutralization efficiency of the wastewater.

[0035] When center disk 201 pushes center disk 311 to rotate via positioning rod, center disk 311 will drive spring telescopic cylinder 312 and center rod 313 to rotate synchronously. As spring telescopic cylinder 312 and center rod 313 rotate, the bottom sidewall of spring telescopic cylinder 312 will slide to the top plane of semicircular plate 322 under the guidance of the inclined surface of semicircular plate 322. During this process, the bottom of center rod 313 will not be obstructed by the sidewall of semicircular plate 322, and the bottom of center rod 313 will be suspended in the air. Then, as center disk 201 drives fixed ring 212 to continue rotating, center disk 201 will rotate in the wastewater. Through contact with the two positioning rods on the central disk 211 and the elasticity inside the spring telescopic cylinder 312, the fixed ring 212 will slide up and down on the surface of the stirring shaft 113 via the central disk 1201. When the central disk 1201 and the perforated plate 211 drive the fixed ring 212 to slide up and down, the wastewater will be disturbed. The wastewater will surge under the sliding of multiple perforated plates 211. By surging the wastewater, the phenomenon of bubbles gathering towards the center of the water after being washed by the edge of the neutralization chamber wall and foam covering the liquid surface can be reduced, the uniformity of the agent being added to the wastewater and mixed can be accelerated, and the neutralization treatment efficiency of the wastewater can be further improved.

[0036] When the notched disc 301 pushes the central disc 311 to rotate via the positioning rod, causing the spring telescopic cylinder 312 to move along the inclined surface of the semicircular plate 322 to the top of the semicircular plate 322, the movement of the semicircular plate 322 will press down on the semicircular plate 323, causing it to slide downwards. As the semicircular plate 323 slides down, it will press down on the elastic frame. Because the bottom of the elastic frame is blocked by the support frame 321, after the semicircular plate 323 applies downward pressure on the elastic frame, the elastic frame will bend and deform in the direction of the semicircular plate 323. At the same time, the deformed elastic frame will generate a reaction force on the sliding semicircular plate 323. When the semicircular plate 323 is in motion, the reaction force of the elastic frame will slow down the rotation speed of the spring telescopic cylinder 312 at the bottom of the spring telescopic cylinder 312. By slowing down the rotation speed of the spring telescopic cylinder 312 driven by the central plate 311, the situation where the notch plate 301 drives the central plate 311 to rotate too quickly due to the high rotation speed of the notch plate 301 is reduced. This improves the stability of the central plate 201 driven by the central plate 311 during the lifting and reciprocating vibration process.

[0037] When the elastic frame of the auxiliary mechanism 3 deforms as it slides down the semicircular plate 323, the top of the elastic plate 324 extends beyond the elastic frame. Since the elastic plate 324 is inclined, when the central disc 311 drives the central rod 313 to slide up and down repeatedly under the elasticity of the spring telescopic cylinder 312, the sliding of the central rod 313 will intermittently push the top of the elastic plate 324. When the top of the elastic plate 324 is pushed by the sliding of the central rod 313, the elastic plate 324 will move closer to the semicircular plate 323 and squeeze the wastewater, causing the wastewater to pass through the holes on the elastic plate 324. The sprayed wastewater can disturb the wastewater between the support frame 321 and the bottom of the central disk 201. By disturbing the wastewater, combined with the reciprocating sliding of the central disk 311, the excessive deposition of impurities in the wastewater between the support frame 321 and the central disk 201 due to the excessively stable wastewater flow rate can be reduced. By reducing the deposition of impurities in this area, the continuity and stability of the operation of the sliding mechanism 2 and the auxiliary mechanism 3 in this area can be ensured, the frequency of subsequent maintenance in this area can be reduced, and the neutralization efficiency of the wastewater can be further enhanced.
