Description

Technical Field

[0001] The utility model relates to the technical field of pickling additive production, in particular to a quantitative feeding mechanism for pickling additive production. Background Art

[0002] Pickling additives are used for pickling of stainless steel oxide scale, because the oxide scale on the surface of stainless steel has a dense structure and strong adhesion to the substrate, so it must be removed before subsequent passivation, electroplating, coloring and other decorative treatments. In the process of stainless steel pickling, its use can promote the removal of various stainless steel black oxide scales and silicate scales, slow down the corrosion of the metal substrate, and inhibit the generation of acid mist. Pickling additives can greatly reduce the corrosion rate of stainless steel under normal use, and have excellent ability to inhibit the absorption of hydrogen by stainless steel during the pickling process, avoiding "hydrogen embrittlement" of stainless steel. At the same time, it inhibits the corrosion of Fe3+ to metal during the pickling process, so that stainless steel does not have pitting corrosion. It is suitable for various types of stainless steel. Pickling additives include acid mist inhibitors, corrosion inhibitors, etc. Pickling additives are generally surface active substances such as wetting agents and emulsifiers. Adding these materials to the pickling solution will reduce the surface tension of the pickling solution and better wet the surface of the steel wire, thereby accelerating the pickling process of the steel wire.

[0003] At present, most quantitative feeding mechanisms are carried out by installing a peristaltic pump on a delivery pipe. The feeding pipe is generally installed directly above the reactor. However, when adding materials, liquid splashing may occur, causing personal injury, and directly discharging liquid raw materials into the reactor will cause a large amount of foam to be generated in the reactor, which is not conducive to continuous and rapid production. Utility Model Content

[0004] In order to solve the problem of liquid splashing and foaming caused by direct discharge of liquid raw materials into a reaction kettle proposed in the above background technology, the purpose of the utility model is to provide a quantitative feeding mechanism for the production of pickling additives.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quantitative feeding mechanism for pickling additive production, comprising a bracket, a silo is mounted on the bracket, a feed pipe is mounted on the lower side of the silo, a mounting plate is mounted on the feed pipe, a discharge head is mounted in the feed pipe, the silo is connected to the discharge head through a connecting hose, a peristaltic pump is mounted on the connecting hose, and the peristaltic pump is mounted on the mounting plate;

[0006] A sleeve is sleeved and fixed on the discharge pipe, a limiting ring is installed on the lower end of the sleeve, a sliding ring is sleeved and slidably mounted on the sleeve, a second plastic ring is installed on the sliding ring, and a splash-proof bucket is installed on the lower end of the second plastic ring.

[0007] Preferably, a protective cover is installed between the sleeve and the silo.

[0008] Preferably, a third plastic ring is sleeved and fixed on the outer side of the splash-proof bucket.

[0009] Preferably, the protective cover is a solid plastic ring, and the third plastic ring is a hollow plastic ring.

[0010] Preferably, a plurality of floating balls are connected in the splash-proof bucket via connecting lines.

[0011] Preferably, the splash guard is provided with air holes.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. When the utility model is used, the utility model is first installed above the reactor through the bracket, and the discharge pipe is ensured to be inserted into the reactor. Then, the first liquid raw material is filled into the reactor. After the first liquid raw material is filled, the splash-proof bucket floats on the liquid surface. Then, the second pickling additive raw material is discharged into the reactor through the peristaltic pump. After the second liquid raw material is discharged from the discharge head, it enters the reactor along the discharge pipe. After the second liquid raw material flows out of the discharge pipe, it will first fall on the floating ball to prevent direct dripping from causing bubbles or splashing. The splash-proof bucket can also prevent the reaction from splashing. Some more intense reactions can also be carried out in the splash-proof bucket to prevent liquid splashing, thereby effectively preventing injuries to personnel caused by liquid splashing.

[0014] 2. A notch is provided at the lower end of the splash-proof bucket of the utility model, which can be used to accelerate the exchange of liquid inside and outside the splash-proof bucket, thereby accelerating the reaction speed. A plurality of floating balls are connected to the splash-proof bucket through connecting lines to prevent the liquid discharged from the discharge head from directly dripping into the reactor to generate a large number of bubbles.

[0025] A plurality of floating balls 121 are connected to the splash-proof bucket 118 through connecting lines to prevent the liquid medicine discharged from the discharge head 104 from generating a large number of bubbles in the splash-proof bucket 118, causing the liquid medicine to scatter, etc., further improving the stability in the reactor.
