Description

Technical Field

[0001] The invention relates to the field of hot-dip galvanized pickling plates, and in particular to a novel environmentally friendly production process and production system of hot-dip galvanized pickling plates. Background Art

[0002] Hot-dip galvanized pickled steel plate is a steel plate that has been specially processed. It combines the advantages of pickling and hot-dip galvanizing technologies and has excellent anti-corrosion performance and surface quality. The environmentally friendly production system of hot-dip galvanized pickled steel plate is a comprehensive system that covers all aspects from raw material processing to final product production, aiming to ensure the environmental protection, efficiency and safety of the production process. The pickling system, as the core link in the production of hot-dip galvanized pickled steel plates, uses pickling liquid to corrode the steel plates, remove surface oxides and impurities, and prepare for the subsequent galvanizing process.

[0003] The invention patent with the current publication number CN117328073A discloses a steel pickling tank, "by setting a motor, a first bevel gear, a second bevel gear, a reciprocating screw and a vibration block, starting the motor, the motor drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the reciprocating screw to rotate, the reciprocating screw drives the vibration block to reciprocate, the vibration block drives the vibration plate to reciprocate, the vibration plate drives the supporting plate to move up and down, the supporting plate drives the steel to move up and down, so that the solution in the pickling tank can be mixed evenly, and the steel can be fully contacted with the pickling solution, thereby improving the problem of poor steel pickling effect". Although it solves the problem that "in the process of pickling steel, the reaction will cause the acid concentration at different positions in the pickling tank to be different, so that the rust on the steel cannot be completely removed, resulting in poor steel pickling effect", However, in the invention, when the steel plate is immersed in the pickling solution for acid etching reaction, the steel plate is directly placed on the "support plate" for moving up and down cleaning. Although the "support plate" is provided with multiple through holes, the parts without through holes are in contact with the steel plate, which will cause the pickling solution to flow poorly in these contacting areas. The obstructed flow will directly affect the uniform distribution of the pickling solution and the full contact with the surface of the steel plate, which may lead to poor pickling effect in certain areas of the steel plate surface, insufficient pickling or uneven pickling. In addition, due to the obstructed flow of the pickling solution, the oxides and impurities on the surface of the steel plate are difficult to be removed in time, so it is necessary to extend the pickling time to ensure the pickling effect. However, too long pickling time will not only increase the production cost, but also may cause excessive corrosion to the steel plate, resulting in a decrease in the surface quality of the steel plate. In addition, a large amount of acid mist will be generated when the steel plate is pickled in the pickling solution, which will have an impact on the environment. Therefore, we propose a new environmentally friendly production process and production system for hot-dip galvanized pickling plates. Summary of the invention

An acid mist detector is installed in the middle of the bottom of the built-in box. The inner cavity of the built-in box is provided with an opening control component, and the opening control component includes a middle groove arranged in the middle of the inner cavity of the built-in box. There are material troughs on both sides of the inner cavity of the built-in box, and the inner cavities of the two material troughs are respectively connected with the inner cavities of the two discharge holes.

[0006] Preferably, both sides of the top end of the side plate are fixedly connected to limit blocks, both sides of the filter screen surface are provided with a pair of through holes, and the inner walls of the through holes are fixedly connected to rubber sleeves.

[0007] Preferably, the two connecting frames are respectively placed on both sides of the bottom of the filter screen, and the top ball is made of soft material to protect the surface of the steel plate.

[0008] Preferably, the ejecting member further comprises two pairs of guide cylinders, the two pairs of guide cylinders are respectively fixed on both sides of the bottom end of the pickling box, and a plurality of balls are embedded in the inner walls of the guide cylinders.

[0009] Preferably, mounting rods are fixedly connected to both sides of the bottom end of the connecting frame, and the bottom ends of the two mounting rods movably penetrate the surface of the pickling box and respectively movably penetrate the inner cavities of the two guide cylinders on the same side, and are installed with pulleys.

[0010] Preferably, slide grooves are provided on both sides of the surface of the device frame, and fixed plates are fixedly connected to both sides of the bottom end of the transmission plate, and the two fixed plates are slidably connected to the two slide grooves respectively.

[0011] Preferably, rolling grooves are provided on both sides of the top of the transmission plate, and the two rolling grooves are respectively rollingly connected to two pulleys on the same side.

[0012] Preferably, a second driving unit is installed in the middle of the inner cavity of the middle groove, and a rotating block is transmission-connected on the output shaft of the second driving unit, and L-shaped movable plates are arranged on both sides of the rotating block.

[0013] Preferably, one end of the two L-shaped movable plates respectively moves through the inner walls on both sides of the middle groove to the inner cavities of the two material grooves, and a spring is connected between one end of the L-shaped movable plate and the inner wall of the middle groove.

[0014] A new environmentally friendly production process for hot-dip galvanized pickled plates, which specifically includes the following steps: S1: Pretreatment: Before pickling, the steel plate is thoroughly cleaned and derusted to remove impurities, stains and rust on the surface to ensure the quality of galvanizing; S2: Prepare pickling solution: Commonly used pickling solutions are hydrochloric acid and sulfuric acid. Choose the appropriate pickling solution according to the pickling requirements and the material of the steel plate. The acidity must be strictly controlled before pouring it into the pickling box to ensure the pickling effect, and then pour it into the pickling box for use; S3: Placing the steel plate: placing the steel plate on the filter screen between the four limit blocks, and using the side plates to limit the steel plate; S4: Dynamic pickling: When the steel plate is pickled, the driving part gives the driving plate a force to make it move left and right, and the rolling groove on it cooperates with the lifting piece, so that the two pairs of lifting balls on both sides lift the two sides of the steel plate in turn. Dynamic cleaning can fully pickle the surface of the steel plate; S5: Adding mist suppressant: During pickling, the acid mist detector monitors the acid mist in the pickling box in real time. When the acid mist diffuses, the acid mist detector transmits a signal to an external control device, which then drives the second drive unit to control the rotation speed of the rotating block to put a certain amount of mist suppressant into the pickling box. Adding mist suppressant can significantly reduce the safety hazards caused by the diffusion of acid mist and improve the environmental protection of the production process. S6: Cleaning the filter: After the steel plate is pickled, take the filter out of the pickling box and clean the oxide impurities on the filter to ensure subsequent reuse.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When the steel plate is placed on the filter screen for pickling, the present invention starts the driving part 1, so that the transmission plate moves linearly to the left or right under the action of the fixed plate and the slide groove. Due to the particularity of the shape of the transmission plate, when the driving part 1 moves to one side, the pulley on one side is placed at a position with a higher slope of the driving part 1, so that the connecting frame drives the vertical rod to move upward, and one side of the steel plate placed on the filter screen is lifted up. Similarly, after the driving part 1 moves to the other side, the other side of the steel plate is lifted up accordingly. The two sides of the steel plate are lifted up in turn, thereby achieving the purpose of dynamic cleaning of the steel plate in the pickling solution. By constantly turning the steel plate, the long-term contact area between the steel plate and the filter screen can be reduced, thereby avoiding the problem of poor circulation of the pickling solution in these contact areas, which helps to improve the uniform distribution of the pickling solution and its sufficient contact with the surface of the steel plate. The filter screen placed in the pickling box can prevent oxide impurities from settling to the bottom of the pickling box after the steel plate is pickled, so as to facilitate the subsequent cleaning of the oxide impurities.

[0016] 2. When the steel plate is pickled in the pickling box, when the acid mist detector detects that the surrounding acid mist concentration is high, the present invention transmits a signal to the external control end, and then the control end starts the second driving part to rotate the rotating block. When the rotating block rotates to a vertical state, the two L-shaped movable plates will move relative to each other under the action of the spring, thereby exposing the feed hole. At this time, the fog suppressant in the material trough is dropped into the pickling box from the feed hole to suppress the acid mist. Through the cooperation of the acid mist detector and the control end, automatic detection and delivery of the fog suppressant are realized, the safety and efficiency of the pickling process are improved, and the delivery amount of the fog suppressant can be controlled by controlling the rotation speed of the rotating block, thereby avoiding waste of the fog suppressant and environmental pollution, suppressing the diffusion of acid mist and achieving the purpose of environmental protection.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1 Please refer to Figure 1-10 The present invention provides a novel environmentally friendly production system for hot-dip galvanized pickling plates, including a device frame 1, which serves as a supporting structure of the entire system and is used to install and fix components such as a pickling box 2. The top of one side of the device frame 1 is fixedly connected with a pickling box 2 for containing pickling liquid and placing steel plates to be pickled. A filter screen 3 is provided in its inner cavity to intercept impurities in the pickling liquid, so as to facilitate subsequent cleaning of impurities in the pickling box 2. The bottom corner of the pickling box 2 is a beveled edge for supporting the filter screen 3. The inner cavity of the pickling box 2 is provided with a filter screen 3, and both sides of the filter screen 3 are fixed. A side plate 4 is connected, and the corners of the side plate 4 are adapted to the beveled shape of the pickling box 2. The two sides of the top of the side plate 4 are fixedly connected with a limiting block 5. When the steel plate is placed on the filter screen 3 and lifted up while cleaning, it is limited. A pair of through holes 6 are opened on both sides of the surface of the filter screen 3. The size of the through hole 6 can allow the top ball 83 to pass through, so that the filter screen 3 can be taken out of the pickling box 2 for cleaning later. The inner wall of the through hole 6 is fixedly connected with a rubber sleeve 7, which prevents impurities in the filter screen 3 from leaking to the bottom through the gap between the through hole 6 and the vertical rod 82; A lifting member 8 is arranged between the filter screen 3 and the pickling box 2, and the lifting member 8 includes two connecting frames 81. Vertical rods 82 are fixedly connected to both sides of the top of the connecting frame 81. The tops of the two vertical rods 82 movably penetrate the inner cavities of the two rubber sleeves 7 on the same side and are fixedly connected to top balls 83. A driving member 9 is arranged at the bottom of the pickling box 2. The driving member 9 includes a driving part 91 installed on a side wall of the device frame 1. The driving part 91 is specifically a cylinder, which provides driving force for the movement of the transmission plate 92. The output end of the driving part 91 is transmission-connected to the transmission plate 92, and both sides of the top of the transmission plate 92 have a certain slope.

[0021] As a further limitation of the top material piece 8 of the present invention, the two connecting frames 81 are respectively placed on both sides of the bottom of the filter screen 3, and the top ball 83 is a soft material used to protect the surface of the steel plate. The top material piece 8 also includes two pairs of guide cylinders 84, which play a guiding and limiting role for the mounting rod 86. The two pairs of guide cylinders 84 are respectively fixed on both sides of the bottom end of the pickling box 2, and the inner wall of the guide cylinder 84 is embedded with a plurality of balls 85. The balls 85 are used to reduce the friction between the mounting rod 86 and the contact surface of the guide cylinder 84. The mounting rods 86 are fixedly connected to both sides of the bottom end of the connecting frame 81, and the bottom ends of the two mounting rods 86 movably penetrate the surface of the pickling box 2. The part of the mounting rod 86 that penetrates the pickling box 2 has a sealing member such as a sealing ring, a deformable sealing film, etc., and movably penetrates the inner cavity of the two guide cylinders 84 on the same side, and is installed with a pulley 87.

[0022] As a further limitation of the driving member 9 of the present invention, slide grooves 93 are provided on both sides of the surface of the device frame 1, and fixed plates 94 are fixedly connected to both sides of the bottom end of the transmission plate 92. The two fixed plates 94 are respectively slidably connected to the two slide grooves 93. Under the action of the slide grooves 93 and the fixed plates 94, the transmission plate 92 is guided and limited, so that it can perform stable linear motion. Rolling grooves 95 are provided on both sides of the top of the transmission plate 92, and the two rolling grooves 95 are respectively rollingly connected to the two pulleys 87 on the same side.

[0023] The specific implementation method of this embodiment is as follows: the staff first pours a portion of the prepared pickling liquid into the pickling box 2, then places the steel plate to be pickled on the filter screen 3 between the four limit blocks 5, and then continues to pour the pickling liquid until the steel plate is completely immersed, and then starts the driving part 91, so that the transmission plate 92 moves back and forth to both sides under the action of the slide groove 93 and the fixed plate 94. During the movement of the transmission plate 92, when part of the pulley 87 moves to the slopes on both sides of the top of the transmission plate 92, the mounting rods 86 on both sides will indirectly lift up in turn, so that the connecting frame 81 and the vertical rod 82 allow the two top balls 83 on one side to lift up one side of the steel plate, thereby causing the steel plate to push the pickling liquid to fluctuate, so that its surface is fully in contact with the pickling liquid, because the two sides are lifted up in turn. The method is that when the top ball 83 on one side lifts the same side of the steel plate upward, the other side of the steel plate is located above the side plate 4 for support. At this time, the bottom of the steel plate is in an inclined state, so that there is a large space between the bottom end of the steel plate and the filter screen 3 for the pickling liquid to flow. In addition, the method of lifting upward in turn is adopted, so that the top ball 83 will not always be in contact with the steel plate, so that the contact point between the top ball 83 and the steel plate will also be in full contact with the pickling liquid, and the steel plate is pickled in all aspects to ensure the pickling effect and uniformity of the steel plate. After the pickling of the steel plate is completed, the filter screen 3 can be taken out of the pickling box 2 as needed, and the impurities on its surface are cleaned. After cleaning, the four through holes 6 of the filter screen 3 are aligned with the four top balls 83, and it is re-placed in the pickling box 2 for use, and it is ready for the next round of pickling of the steel plate.

[0024] Embodiment 2 Please refer to Figure 1-10 The present invention provides a novel environmentally friendly production system for hot-dip galvanized pickling plates. A built-in box 10 is fixedly connected to one side of the top of the device frame 1. Both sides of the bottom of the built-in box 10 are provided with discharge holes 11 for feeding fog suppressants. An acid mist detector 12 is installed in the middle of the bottom of the built-in box 10 for real-time monitoring of the acid mist concentration generated during the pickling process. When the acid mist concentration exceeds a preset threshold, an alarm can be triggered or the pickling parameters can be automatically adjusted to ensure the environmental protection of the production process. The prior art will not be repeated. The inner cavity of the built-in box 10 is provided with an opening control member 13, and the opening control member 13 includes a middle groove 131 disposed in the middle of the inner cavity of the built-in box 10. Both sides of the inner cavity of the built-in box 10 are provided with material grooves 132. The interior of the material groove 132 is provided with fog suppressants for suppressing acid mist, thereby achieving the purpose of environmental protection. The inner cavities of the two material grooves 132 are respectively connected to the inner cavities of the two discharge holes 11.

[0025] As a further limitation of the opening control member 13 of the present invention, a driving unit 133 is installed in the middle of the inner cavity of the middle groove 131, specifically a motor, which provides driving force for the rotation of the rotating block 134. The output shaft of the driving unit 133 is connected to the rotating block 134 in a transmission manner. The rotating block 134 is elliptical. In its vertical state, the two L-shaped movable plates 135 move relative to each other, and the fog suppressant will be dropped into the pickling box 2 through the discharge hole 11. When it is horizontal, the L-shaped movable plate 135 will block the discharge hole 11. L-shaped movable plates 135 are arranged on both sides of the rotating block 134. One end of the two L-shaped movable plates 135 respectively moves through the inner walls of the two sides of the middle groove 131 to the inner cavities of the two material grooves 132. A spring 136 is connected between one end of the L-shaped movable plate 135 and the inner wall of the middle groove 131 to ensure that the L-shaped movable plate 135 automatically returns to the initial position.

[0026] The specific implementation of this embodiment is as follows: a cavity in which two material troughs 132 can be placed is provided, and two material discharge holes 11 are blocked by two L-shaped movable plates 135, so that the two material troughs 132 can store different ingredients for auxiliary pickling, such as fog suppressants, and the inner wall of the material trough 132 is set as an inclined surface, which is more conducive to the smooth discharge of the fog suppressants and avoids material accumulation. When the steel plate is pickled, when the acid mist detector 12 detects that the acid mist concentration exceeds the standard, it will transmit a signal to the external control end, and then the control end controls the driving part 133 to start automatically, and the driving part 133 drives the rotating block 134 to rotate to a vertical state, which can be adjusted by adjusting the driving part The rotation speed of the second part 133 is adjusted to slow down or speed up the rotation speed of the rotating block 134, so that the time taken by the rotating block 134 to change from a horizontal state to a vertical state and then to a horizontal state is increased or decreased, so that more or less defogging agent leaks out from the discharge hole 11 during this time period, thereby achieving the effect of controlling the amount of defogging agent released. Under the action of the spring 136, the two L-shaped movable plates 135 move relative to each other, opening the discharge hole 11, and allowing the defogging agent in the material trough 132 to be discharged into the pickling box 2 through the discharge hole 11, so as to suppress acid mist and thereby improve the environmental protection in the pickling process.

[0027] Embodiment 3 The present invention provides a novel environmentally friendly production process for hot-dip galvanized pickling plates, which together with a production system constitutes a novel environmentally friendly production process and production system for hot-dip galvanized pickling plates, which specifically includes the following steps: S1: Pretreatment: Before pickling, the steel plate is thoroughly cleaned and rust-removed (cleaning methods include chemical cleaning, electrolytic cleaning and physical cleaning, etc., which are usually combined according to actual needs to achieve the best cleaning effect) to remove surface impurities, stains and rust to ensure the quality of galvanizing. After cleaning, the steel plate should be dried to prevent moisture from entering the pickling box 2, affecting the pickling effect or causing safety hazards; S2: Prepare pickling solution: Common pickling solutions include hydrochloric acid and sulfuric acid. Select appropriate pickling solution according to pickling requirements and steel plate material. The acidity must be strictly controlled before pouring it into the pickling tank 2 to ensure the pickling effect. Then pour it into the pickling tank 2 for use. It is also necessary to regularly test the composition and concentration of the pickling solution to ensure that it is always in the best working condition; S3: Placing the steel plate: placing the steel plate on the filter screen 3 between the four limiting blocks 5, and using the side plates 4 to limit the steel plate; S4: Dynamic pickling: When the steel plate is pickled, the driving part 91 is used to give force to the transmission plate 92, so that it moves left and right, and the rolling groove 95 on it cooperates with the lifting member 8, so that the two pairs of lifting balls 83 on both sides lift up the two sides of the steel plate in turn. Dynamic cleaning can fully pickle the surface of the steel plate; S5: Adding mist suppressant: During pickling, the acid mist detector 12 monitors the acid mist in the pickling box 2 in real time. When the acid mist diffuses, the acid mist detector 12 transmits a signal to an external control device, and then the control device drives the driving part 2 133 to control the rotation speed of the rotating block 134 to put a certain amount of mist suppressant into the pickling box 2. Adding mist suppressant can significantly reduce the safety hazards caused by the diffusion of acid mist and improve the environmental protection of the production process. The selection of mist suppressant should take into account its impact on the environment and human body, and select environmentally friendly and low-toxic mist suppressant; S6: Cleaning the filter 3: After the pickling of the steel plate is completed, take out the filter 3 from the pickling box 2, clean the oxide impurities on the filter 3 to ensure subsequent reuse, and regularly inspect and maintain the filter 3, including checking its integrity, cleanliness and wear, and replacing the damaged or severely worn filter 3 in time.

The novel environmentally friendly production system of hot-dip galvanized pickled plates according to claim 8 is characterized by: One end of the two L-shaped movable plates (135) is movable through the inner walls on both sides of the middle groove (131) to the inner cavities of the two material grooves (132), and a spring (136) is connected between one end of the L-shaped movable plate (135) and the inner wall of the middle groove (131).

10. An environmentally friendly production process for a new type of hot-dip galvanized pickled plate applicable to claims 1-9, which specifically comprises the following steps: S1: Pretreatment: Before pickling, the steel plate is thoroughly cleaned and derusted to remove impurities, stains and rust on the surface to ensure the quality of galvanizing; S2: Prepare pickling solution: Common pickling solutions include hydrochloric acid and sulfuric acid. Select a suitable pickling solution according to the pickling requirements and the material of the steel plate. The acidity must be strictly controlled before pouring it into the pickling box (2) to ensure the pickling effect. Then pour it into the pickling box (2) for use; S3: Placing the steel plate: placing the steel plate on the filter screen (3) between the four limiting blocks (5), and using the side plates (4) to limit the position of the steel plate; S4: Dynamic pickling: When the steel plate is pickled, the driving part (91) applies force to the transmission plate (92) to make it move left and right, and the rolling groove (95) on it cooperates with the lifting member (8), so that the two pairs of lifting balls (83) on both sides lift up the two sides of the steel plate in turn. Dynamic cleaning can fully pickle the surface of the steel plate; S5: Adding a mist suppressant: During the pickling process, the acid mist detector (12) monitors the acid mist in the pickling box (2) in real time. When the acid mist diffuses, the acid mist detector (12) transmits a signal to an external control device, which then drives the second drive unit (133) to control the rotation speed of the rotating block (134) to add a certain amount of a mist suppressant into the pickling box (2). Adding a mist suppressant can significantly reduce the safety hazards caused by the diffusion of acid mist, while improving the environmental friendliness of the production process. S6: Cleaning the filter (3): After the steel plate is pickled, the filter (3) is taken out of the pickling box (2) and the oxide impurities on the filter (3) are cleaned to ensure subsequent reuse.
