Description
Technical Field
The utility model relates to a bearing frame cooling water course incrustation scale belt cleaning device.
Background
Dirt in a water-cooling water channel of a water-cooling bearing seat of a billet conveying roller way is particularly easy to occur on a heat transfer surface, so that the heat transfer efficiency is reduced to influence heat transfer, the dirt in the water channel narrows and reduces the water channel, the water-cooling effect is seriously influenced, the service life of a bearing is shortened, and the production is abnormally interrupted. The cleaning of the scale of the water channel of the water-cooled bearing seat of the billet conveying roller way in the metallurgical industry is not ideal enough in various methods at present, the cleaning wastes time and labor, the cleaning effect is not good, and the scale can be formed again in a short time after the cleaning, so that the production cost is high.
Disclosure of Invention
An object of the utility model is to provide a bearing frame cooling water course incrustation scale belt cleaning device, it is fast to wash, and the cleaning performance is good, can improve work efficiency, reduction in production cost greatly.
The utility model aims at realizing like this, a bearing frame cooling water course incrustation scale belt cleaning device, including sour case and acid-proof pump, sour case is two, and one is high-order sour case, and another is low-order sour case, is setting up the gas vent on the high-order sour roof surface respectively and is advancing acid pipe, and high-order sour case lower extreme is setting up a play acid pipe, and a play acid pipe is linked together with the water-cooling water course of steel billet rollgang water-cooling bearing frame, the water-cooling water course with low-order sour case be linked together, the lower extreme liquid outlet of low-order sour case is being connected respectively acid-proof pump and a clean water pipe, the liquid outlet of acid-proof pump with high-order sour case advance acid pipe and be linked together, the clean water tank is being connected to the clean.
The utility model discloses belt cleaning device especially is applicable to under the operating mode conditions such as the complicated, the easy scale deposit of temperature on the high side of waterway structure, the occasion such as water-cooling bearing frame or water cooling plant that require height to the water-cooling. Has the advantages of high work efficiency, good effect, low cost, simple process, etc. The method can be widely applied to cleaning of water cooling devices in various fields with high requirements on water cooling conditions.
The utility model provides an acid tank, clear water tank can be with nonrust material welding preparation, purchase finished product such as acid-proof pump, valve, plastic tubing or nonrust steel pipe for the pipeline. The volumes of the acid tank and the water tank are 15-20L, and the inner diameter of the pipeline is 15 mm.
Hydrochloric acid is generally selected for effective removal of scale in waterways, and organic acids such as citric acid and formic acid are also useful, but are expensive. For stainless steel materials, nitric acid or organic acids are generally used. Because the water-cooled bearing seat is made of plain carbon steel, hydrochloric acid is selected. Through comparison and test, the hydrochloric acid solution with the concentration of 25% is selected, the effect is best, and the method is economical.
Analysis shows that in the water circulation cooling system, the generation of dirt (mainly scale) and calcium carbonate (CaCO)3) Plays a decisive role, since its water solubility is poor and the solubility decreases with increasing water temperature, at 20 ℃ the solubility is 59 ppm. The scale is generally composed primarily of calcium carbonate (CaCO)3) And a certain amount of silicate, therefore, when the scale is cleaned, hydrochloric acid is selected for cleaning, and 0.5% of sodium fluoride or hydrogen fluoride is additionally added.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of the connection structure of the present invention.
Detailed Description
The utility model provides a bearing frame cooling water course incrustation scale belt cleaning device, as shown in figure 1, including sour case and acid-proof pump, sour case is two, one is high-order sour case 2, another is low-order sour case 6, is setting up gas vent 1 and acid inlet pipe 9 on the 2 top surfaces of high-order sour case respectively, and 2 lower extremes of high-order sour case are setting up an acid outlet pipe 3, and acid outlet pipe 3 is linked together with the water-cooling water course of billet rollgang water-cooling bearing frame 4, the water-cooling water course with low-order sour case 6 be linked together, the lower extreme liquid outlet of low-order sour case 6 is being connected respectively acid-proof pump 8 and a clean water pipe 7, the liquid outlet of acid-proof pump 8 with high-order sour case acid inlet pipe 9 be linked together, clean water pipe 5 is being connected to the other.
When the device is used, the bearing seats are connected in series to test water without leakage or seepage, then the drained water is connected into the acid liquid pipe, and the valve is closed. The acid box is hung on a high frame, an exhaust port is arranged, whether a closed valve is closed or not is checked, a pipeline is connected, the pipeline is connected with a bearing seat pipe, the valve is closed, a lower cylinder valve 1/3 is opened, a bearing seat valve 1/4 is opened, acid flows slowly, all pipelines are checked, and after no leakage exists, the valves of the high-position acid box and the low-position acid box are fully opened, and the bearing seat connecting valves are opened.
In the acid washing process, the acid-resisting pump is timely started or stopped according to the acid amount of the low-position acid tank, so that the circulation of acid liquor is ensured. During the pickling operation, 2 persons are required to operate, and according to the specification of a Chinese Lao character 2003-6, a barrel of clean water is required to be prepared on site for standby when a worker wears the protective clothing and the acid-resistant gloves. The alkali neutralization procedure is the same as the acid washing procedure, wherein the neutralization time is 2 h.
