Description

Technical Field

[0001] This utility model belongs to the technical field of cold rolling pickling equipment, and specifically relates to an acid liquid guide for cold rolling pickling equipment. Background Technology

[0002] The acid volume in the pickling tank of the cold rolling pickling line unit needs to be maintained within a certain range, and the acid needs to be recycled in the pickling process. The acid is controlled to enter and exit the pickling tank by the return bucket and the overflow bucket, and the outlets of the return bucket and the overflow bucket need to be collected into an acid pipeline by the guide.

[0003] Currently, commonly used acid diverters are chambers with a three-way valve, which have the following problems:

[0004] 1. Weak flow guiding effect: Existing flow guides rely on the opposing flow of acid liquids on both sides within the cavity to relieve pressure. The flow guiding structure is simple, resulting in a weak flow guiding effect.

[0005] 2. High maintenance costs: The inlet and cavity of the flow guide are manufactured as a whole. If the inlet is damaged, the entire flow guide needs to be disassembled and repaired, resulting in high maintenance costs. Utility Model Content

[0006] This invention addresses the problems of existing acid flow guides by providing an acid flow guide for cold rolling pickling equipment. This invention facilitates replacement of the flow guide and reduces maintenance costs by adding a flow guiding structure inside the flow guide and redesigning the flow guide nozzle.

[0007] An acid flow guide for a cold rolling pickling equipment includes a cavity, a flow guiding structure, an outlet, a first inlet pipe, a second inlet pipe, a third inlet pipe, a fourth inlet pipe, a fifth inlet pipe, a first inlet conduit, and a second inlet conduit.

[0008] The cavity is flat and round;

[0009] The first and second inlet ports are located at the top of the cavity. The third and fourth inlet ports are symmetrically arranged on both sides of the cavity. The fifth inlet port and the outlet port are symmetrically arranged on both sides of the cavity, and are arranged perpendicular to the third and fourth inlet ports. The flow guiding structure is a flow guide plate, consisting of two plates, which are disposed inside the cavity. The two flow guide plates are vertically fixed on both sides of the fifth inlet port. One side and the bottom edge of the flow guide plate are sealed to the inside of the cavity, and the height of the flow guide plate is lower than the height of the cavity. The first and second inlet conduits are symmetrically arranged. Both the first and second inlet conduits are straight pipes, with one end outside the cavity and the other end inside the cavity. The end of the straight pipe inside the cavity is connected to a bend. The first inlet conduit is sealed in the third inlet port by a flange, and the second inlet conduit is sealed in the fourth inlet port by a flange.

[0010] Furthermore, in the acid guide device for the aforementioned cold rolling pickling equipment, the first inlet and the second inlet are symmetrically arranged on both sides of the central axis of the cavity.

[0011] Furthermore, in the acid flow guide for the cold rolling pickling equipment described above, the bends of the first and second inlet conduits have a curvature of 45°.

[0012] Furthermore, in the acid flow guide for the cold rolling pickling equipment described above, one side of the two flow guides faces the third and fourth inlet pipes respectively, and the length of the bends of the first and second inlet pipes within the cavity does not exceed the horizontal extension line of the adjacent flow guide.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] 1. Increased backflow effect: This utility model optimizes the internal structure of existing flow guides, effectively increasing the internal flow guiding effect of the flow guide.

[0015] 2. Reduced maintenance costs: This utility model improves the pipe opening, effectively reducing maintenance costs. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with embodiments. These embodiments are used to illustrate this utility model but are not intended to limit its scope. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0021] Example

[0022] An acid flow guide for a cold rolling pickling equipment includes a cavity 1, a flow guiding structure 2, an outlet 3, a first inlet pipe 8, a second inlet pipe 7, a third inlet pipe 6, a fourth inlet pipe 5, a fifth inlet pipe 4, a first inlet conduit 10, and a second inlet conduit 9.

[0023] The cavity is flat and round;

[0024] The first and second inlet ports are located at the top of the cavity and are symmetrically arranged on both sides of the cavity's central axis. The third and fourth inlet ports are symmetrically arranged on both sides of the cavity. The fifth inlet port and the outlet port are symmetrically arranged on both sides of the cavity, and are arranged perpendicular to the third and fourth inlet ports. The flow guiding structure is a flow guide plate, consisting of two plates disposed inside the cavity. The two flow guide plates are vertically fixed on both sides of the fifth inlet port. One side and the bottom edge of each flow guide plate are sealed to the inside of the cavity, and the height of the flow guide plate is lower than the height of the cavity. The first and second inlet conduits are symmetrically arranged. Both are straight pipes, with one end outside the cavity and the other end inside. The end of the straight pipe inside the cavity is connected to a bend. The bend of the first and second inlet conduits has a curvature of 45°. The first inlet conduit is sealed in the third inlet port by a flange, and the second inlet conduit is sealed in the fourth inlet port by a flange. One side of each of the two guide plates faces the third and fourth inlet ports, respectively. The length of the bend of the first and second inlet conduits inside the cavity does not exceed the horizontal extension line of the adjacent guide plate.

[0025] The principle and usage of this utility model's flow guide are as follows:

[0026] To address the problem of poor flow guidance in existing acid flow guides, this invention incorporates a special flow guiding structure within the acid flow guide. This structure directs the liquid flow from inlets of different directions to the outlet, preventing collisions, stress relief, and turbulence within the flow guide. Furthermore, both the first and second inlet conduits are detachable for easy repair and maintenance.

[0027] The specific usage method is as follows:

[0028] The guide of this utility model is connected to the pickling tank return hopper, the pickling tank rapid return pipe and the overflow hopper pipe. The pickling tank rapid return pipe is connected to the first liquid inlet and the second liquid inlet respectively. The pickling tank return hopper pipe is connected to the third liquid inlet through the first liquid inlet pipe and to the fourth liquid inlet through the second liquid inlet pipe. The overflow hopper pipe is connected to the fifth liquid inlet.

[0029] The liquid flowing in from the fifth inlet is guided by the flow guide structure and flows forward in a straight line into and out of the liquid outlet. The liquid flowing in from the third inlet is guided by the first inlet conduit, turns 45°, and flows obliquely into and out of the liquid outlet. The liquid flowing in from the fourth inlet is guided by the second inlet conduit, turns 45°, and flows obliquely into and out of the liquid outlet. The liquid flowing in from the first and second inlet flows vertically downward into the flow guide and merges with the liquid flowing in from other inlets before flowing into and out of the liquid outlet.

[0030] When the flow guide needs maintenance after a period of use, simply remove the flanges connecting the first and third inlet pipes, as well as the flanges connecting the second and fourth inlet pipes, and replace the two pipes for repair. This eliminates the need to replace the entire flow guide, reducing costs and maintenance time.
