Description

Technical Field

[0001] The utility model relates to the technical field of metal surface treatment, in particular to a pickling additive modulation device. Background Art

[0002] The oxide scale on the surface of stainless steel has a dense structure and strong adhesion to the substrate. Pickling must be performed before passivation, electroplating, coloring and other decorative treatments to remove the oxide scale. Pickling additives are used for pickling of stainless steel oxide scales. In order to reduce the impact of pickling additives on the environment, a new type of HG high-efficiency and environmentally friendly pickling additive has been born. Traditional pickling additive production equipment is mostly manually operated. During the production process, there is a risk of acidic liquid splashing onto the operator's skin during stirring, which is less safe.

[0003] After searching, it was found that a dispersing device for the production of HG high-efficiency and environmentally friendly pickling additives with a publication number of CN 217189106 U is provided with a filling port and a swinging device. When stirring starts, the swinging plate has a certain reverse stirring effect on the pickling additive, so that the stirring is more uniform, and the pickling additive is beaten in the reverse direction, thereby blocking its rotation speed. By setting the resistance hole, the resistance of the pickling additive to the swinging plate is reduced, the splashing force during stirring is reduced, and the safety factor of the workers is improved.

[0004] In the above technical solution, in actual operation, the torsion spring used to drive the swing plate to rotate will come into contact with the acid. The torsion spring is usually made of metal material and is easily corroded by long-term contact with the acid. The service life is short, which makes the maintenance cost of the subsequent equipment high and is not conducive to the production of pickling additives. Utility Model Content

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. "Multiple" in this specification refers to two or more.

[0025] In the description of this specification, the description with reference to the terms "embodiment", "one embodiment" and "one implementation" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or implementation are included in at least one embodiment or implementation of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or implementation. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0026] Combination Figure 1-6 As shown, an embodiment of the utility model provides a pickling additive modulation device, including: a stirring kettle, a stirring port is provided in the middle of the top of the stirring kettle, an annular sealing groove is provided on the inner wall of the stirring port, a stirring rod passes through the stirring port and enters the interior of the stirring kettle, the stirring rod is rotatably connected to the stirring kettle, a stirring port is provided on one side of the stirring port, the stirring port is arranged in a flange structure, and is convenient for use with a feeding mechanism, a plurality of groups of blocks are evenly distributed on the inner wall of the stirring kettle, the blocks are fixedly connected to the stirring kettle, a splash guard is provided on the stirring rod, the splash guard is connected to the stirring rod, the stirring rod and the splash guard are nested and clamped, the stirring rod can drive the splash guard to rotate, and the edge of the splash guard is in contact with the inner wall of the stirring kettle, and by setting the splash guard, the cross section of the stirring kettle is shielded, which effectively prevents liquid from splashing out of the stirring port during stirring, thereby improving the safety of the stirring kettle.

[0027] The splash shield is in an umbrella-shaped structure, and the top edge of the splash shield is in contact with the block. By setting the block, the splash shield is constantly in contact with the block during the rotation of the stirring rod, thereby generating vibration, thereby preventing particles fed from the feed port from staying on the surface of the splash shield, resulting in a decrease in the accuracy of the raw material ratio, and preventing the liquid from splashing while avoiding affecting the addition of the raw materials. A number of pressure relief holes are provided on the surface of the splash shield, and the liquid raw materials added from the feed port can fall to the bottom of the stirring kettle from the pressure relief holes and the gap between the splash shield and the inner wall of the stirring kettle, thereby reducing the impact of the agitated liquid on the splash shield during the stirring process, avoiding rapid wear of the connection between the splash shield and the stirring rod, and extending the service life of the device.

[0028] The side wall of the stirring rod is fixedly connected to a plurality of stirring blades, which are staggered around the stirring rod, and a plurality of pressure reducing holes are provided on the surface of the stirring blades. By providing the pressure reducing holes, the impact of the liquid on the stirring blades during stirring is effectively reduced, thereby extending the service life of the stirring blades. A baffle is fixedly connected to the middle of the stirring rod, and the inner diameter of the bottom of the splash guard is smaller than the outer diameter of the baffle. The baffle has a supporting force for the splash guard to prevent the splash guard from falling off from the upper part of the stirring rod, thereby reducing the connection wear between the splash guard and the stirring rod. A sealing convex ring is fixedly connected to the upper part of the stirring rod, and the sealing convex ring structure is adapted to the sealing groove. When the stirring rod and the stirring kettle are installed, the sealing convex ring is embedded in the sealing groove to improve the sealing performance of the stirring kettle and prevent liquid from seeping out of the stirring port during stirring.

[0029] Working principle: When in use, the feed port is connected to the feeding system through a flange or directly opened for manual feeding. A motor base is installed at the stirring port, and the motor output shaft is connected to the stirring rod and drives it to rotate. The stirring paddle rotates with the stirring rod. During the rotation, part of the liquid passes through the pressure reducing hole to reduce the impact of the liquid on the stirring paddle. The rotation of the stirring rod drives the splash guard to rotate synchronously. Most of the liquid splashing inside the stirring kettle is blocked when it hits the splash guard to prevent the liquid from splashing from the feed port and contacting the human body during manual feeding, affecting human health. A small amount of liquid flows out from the pressure relief hole to reduce the impact of the splashing liquid on the splash guard. At the same time, the splash guard constantly collides with the block to generate vibration during rotation to prevent the added granular raw materials from staying on the splash guard, resulting in a decrease in the accuracy of the raw material ratio.

[0030] Although the disclosure is as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the utility model.
