Technical Field

[0001] This utility model relates to the field of buffering for pickling heaters, and more particularly to a buffering mechanism for pickling heaters. Background Technology

[0002] In modern industrial production, pickling is widely used in metal processing, chemical industry, electroplating and other fields. The purpose of pickling is to remove impurities such as oxide scale and rust from the metal surface to improve the surface quality and subsequent processing performance of the metal. The pickling heater is a key piece of equipment in the pickling process. Its function is to heat the pickling solution, thereby accelerating the pickling reaction and improving production efficiency.

[0003] However, during the actual operation of the pickling heater, the flow generated by squeezing the solution after placing the object into the pickling tank will exert an impact force on the heating tubes and other components inside the heater. Under long-term action, this will cause the heating tubes to wear, deform, or even break, shortening their service life, increasing equipment maintenance costs and downtime, and thus affecting the continuity and stability of production. To address these issues, a buffer mechanism for the pickling heater is proposed. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a buffer mechanism for an acid pickling heater, comprising a tank body and two sets of heating tubes disposed near the inner walls of the left and right sides of the tank body. Buffer components are disposed on both the left and right sides of the tank body.

Four sets of fixing plates are fixedly connected to the inner walls of both the left and right sides of the tank body. A piston rod is fixedly connected to the opposite face of every two sets of fixing plates. Springs are sleeved on the outer walls of the piston rods. Rectangular sliders are piston-connected to the outer sides of the piston rods. Two sets of rectangular pressing blocks are fixedly connected to the inner walls of the two sets of protective frames. The springs are respectively disposed between the fixing plates and the rectangular sliders.

[0008] As a further description of the above technical solution:

[0009] The outer sides of the multiple sets of rectangular extrusion blocks are all triangular, and the multiple sets of rectangular sliders are slidably connected to the inner walls of the left and right sides of the pool body.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a buffer mechanism for an acid pickling heater, comprising a tank body 1 and two sets of heating pipes 4 disposed near the inner walls of the left and right sides of the tank body 1. The tank body 1 and the heating pipes 4 form the shell and internal structure of the acid pickling heater. Buffer components 2 are provided on both the left and right sides inside the tank body 1. Each buffer component 2 includes two sets of sliding plates 21 providing support. Both sets of sliding plates 21 are slidably connected to the top left and right sides of the tank body 1. Protective frames 23 are fixedly connected to the bottom of each set of sliding plates 21. Blocks 22 protecting the heating pipes 4 are fixedly connected to the inner sides of each set of protective frames 23. The two sets of protective frames 23 and blocks 22 are respectively disposed on the outer sides of the two sets of heating pipes 4. Sliding grooves 24 are provided on the inner walls of the left and right sides of the tank body 1, which are slidably connected to the protective frames 23, allowing the protective frames 23 to slide on the inner walls of the sliding grooves 24. One end is fixed with a rubber pad to increase friction and sealing effect. Two sets of protective frames 23 are slidably connected to the inner walls of two sets of sliding grooves 24. Four sets of fixed plates 28 are fixedly connected to the inner walls of the left and right sides of the pool body 1 to provide support. Piston rods 210 supporting the movement of rectangular sliders 27 are fixedly connected to the opposite surfaces of each pair of fixed plates 28. Springs 29 that make the rectangular sliders 27 quickly return to their original position are sleeved on the outer walls of multiple sets of piston rods 210. Rectangular sliders 27 that cooperate with rectangular extrusion blocks 26 to extrude and extrude springs 29 are piston-connected to the outside of multiple sets of piston rods 210. Two sets of rectangular extrusion blocks 26 are fixedly connected to the inner walls of the two sets of protective frames 23 to extrude and extrude two sets of rectangular sliders 27 to move outward. Multiple sets of springs 29 are respectively set between multiple sets of fixed plates 28 and multiple sets of rectangular sliders 27.

[0032] Reference Figure 2 , Figure 4 and Figure 5 The inner sides of multiple sets of rectangular sliders 27 are all set with bevels, and multiple sets of rectangular extrusion blocks 26 are respectively inserted between every two sets of rectangular sliders 27. The outer sides of the multiple sets of rectangular extrusion blocks 26 are all set with triangles. By the triangular rectangular extrusion blocks 26 extruding the bevels of the rectangular sliders 27, the two sets of rectangular sliders 27 move outward and extrude the springs 29, which can buffer the impact force of the stop block 22. At the same time, the piston rod 210 is connected to the piston of the rectangular slider 27, and works with the air discharge through hole 211 to achieve a damping effect, further improving the buffering effect. The multiple sets of rectangular sliders 27 are respectively slidably connected to the inner walls of the left and right sides of the pool body 1. Hydraulic rods 25 are fixedly installed in the middle of the inner walls of the left and right sides of the pool body 1. The damping effect of the hydraulic rods 25 further improves the buffering effect. Each pair of rectangular sliders 27 has through holes 211 on their opposite sides.

[0033] Reference Figure 1 , Figure 2 and Figure 3The inner sides of the two sets of sliding plates 21 and the two sets of stop blocks 22 are provided with protective components 3. The two sets of protective components 3 include four sets of mounting slots 32 and four sets of mounting blocks 34, which provide support and stable movement. Each two sets of mounting slots 32 are respectively opened at the top of the two sets of sliding plates 21 and the opening is located inside the sliding plate 21. Multiple sets of mounting blocks 34 are respectively inserted into the inner wall of multiple sets of mounting slots 32. Each two sets of mounting blocks 34 are respectively fixedly connected to the top of a baffle 31 that first blocks the impact force of the water flow. Both sets of baffles 31 are L-shaped. The L-shaped design can support the sliding plate 21 and block the impact of the water flow at the same time. The two sets of baffles 31 are respectively installed on the outer sides of the two sets of sliding plates 21 and the two sets of stop blocks 22. The top of the two sets of baffles 31 are through and respectively threaded onto the top of the two sets of sliding plates 21 by two sets of bolts 33. The baffles 31 can be installed and supported by the bolts 33 threaded onto the sliding plate 21.

[0034] Working Principle: During operation of the pickling heater, when the impact force generated by the flow of the pickling solution acts on the area around the heating tube 4, the impact force is first transmitted to the baffle 31. The baffle 31 is fixedly installed on the stop block 22, and the stop block 22 is fixedly connected to the protective frame 23. The protective frame 23 is also connected to the sliding plate 21, which can slide on the left and right sides of the top of the tank 1. At the same time, the protective frame 23 slides along the grooves 24 on the inner walls of the left and right sides of the tank 1. The rubber pads on the inner walls of the grooves 24 increase friction and sealing effect. The rectangular extrusion blocks 26 inside the protective frame 23 move with the movement of the protective frame 23. Since the inner side of the rectangular slider 27 is inclined and the outer side of the rectangular extrusion block 26 is triangular, the rectangular extrusion block 26 inserts into every two sets of rectangular... Between the sliders 27, as the protective frame 23 moves, the inclined surface of the rectangular extrusion block 26 presses against the inclined surface of the rectangular slider 27, causing the two sets of rectangular sliders 27 to move outward. The rectangular sliders 27 are piston-connected on the piston rod 210. When they move outward, they will compress the spring 29 sleeved on the piston rod 210. The spring 29 is compressed and stores elastic potential energy, thereby absorbing part of the impact force. Moreover, when the rectangular sliders 27 move, the internal air is discharged from the through hole 211, which produces a damping effect and slows down the moving speed of the rectangular sliders 27. Together with the spring 29, the impact force is further buffered. The hydraulic rods 25 installed in the middle of the inner walls on both sides of the pool body 1 will also use their own damping characteristics to enhance the overall buffering effect, thereby protecting the heating tube 4 from damage by excessive impact force.

[0035] In addition, when there is water flow impact, the protective components 3 inside the slide plate 21 and the baffle 22 come into play. The impact force of the water flow first acts on the baffle 31. The L-shaped baffle 31 can effectively block the water flow impact. It is connected to the mounting groove 32 at the top of the slide plate 21 by the mounting block 34 and is threadedly installed at the top of the slide plate 21 by the bolt 33, which is firmly fixed. This not only blocks the impact of water flow on the heating tube 4, but also protects the related structure of the buffer component 2, ensuring the stable operation of the entire buffer mechanism and continuously providing reliable buffer protection for the acid pickling heater. At the same time, the bolt 33 can be used for quick replacement and maintenance.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
