Abstract

The utility model discloses a pickling tank, which consists of a tank body and a tank cover, wherein a sealing bar is arranged at the contact surface of the tank body and the tank cover; at least one exhaust port is formed in a position above a liquid level line on the side face of the tank body, and a liquid outlet and a liquid filling hole are formed in the bottom of the tank body; the liquid outlet and the liquid filling hole are connected with a circulating pump respectively through a circulating pipe; the other end of the circulating pump is communicated with a mixing tank through a circulating pipe; the mixing tank consists of a bracket and a tank body; a main liquid filling hole, at least one auxiliary liquid filling hole and at least one air return hole are formed in the top of the tank body, and a drain outlet and a liquid return hole are formed in the bottom of the tank body; the auxiliary liquid filling hole and the liquid return hole are communicated with the circulating pump through a circulating pipe; the air return hole is communicated with the exhaust port through an air pipe; at least one PH value sensor is arranged below the inner surface of the tank cover and the liquid level line on the side face of the tank body respectively. The pickling tank is small in floor area, and is low in energy consumption. Meanwhile, the recycling of acid gas is added, so that the acidity stability of acid liquor is improved, and meanwhile the defect of non-uniform concentration distribution of acid liquor is overcome.

Description

A kind of descaling bath

Technical field

The utility model relates to a kind of descaling bath, belongs to pickler field.

Background technology

Carrying out in industrial production, often many various metals or nonmetal raw material or semi-finished product are carried out to soak acid-cleaning processing in the acid solution of descaling bath, because the acid strength for pickling is relatively high, volatility is stronger, thereby cause descaling bath to produce a large amount of volatile acidic gas, environment and operating personnel's health has been formed to serious threat, for this problem extracurriliar, conventional way is that descaling bath lid is sealed at present, or after sealing and with blower fan, volatile acidic gas is delivered to special cleaning equipment place and carries out purified treatment, although these traditional methods can reduce the harm of sour gas to surrounding enviroment and personnel health to a certain extent, but it is not thorough still to exist processing, occupation area of equipment is large, complex treatment process, energy consumption is large and along with the transfer processing of the sour gas volatilizing also being greatly reduced to the concentration of acid solution, thereby affect pickling effect, and cause the serious wasting of resources.

Simultaneously, in acid cleaning process, due to majority time, be material to be left standstill in acid solution to immersion, thereby very easily cause the CONCENTRATION DISTRIBUTION of acid solution inhomogeneous, approximately near lower by pickling material place concentration, reduce on the one hand thus pickling quality and efficiency, also very easily allow operating personnel take for acid strength on the other hand not up to standard, and acid solution is changed, thereby cause great acid solution waste, greatly increase production cost.

Utility model content

The utility model object is just to overcome above-mentioned deficiency, and a kind of descaling bath is provided.

For achieving the above object, the utility model is to be achieved through the following technical solutions:

A kind of descaling bath, formed by cell body and groove lid, it is characterized in that: described cell body and groove lid contact-making surface place establish sealing strip, at least one exhaust outlet is established in the described above position of liquid level line, cell body side, a leakage fluid dram and a filling opening are established in bottom, described leakage fluid dram and filling opening spacing are 1/3-2/3 of cell body length, described leakage fluid dram and filling opening are separately connected with circulating pump by circulation pipe respectively, the described circulating pump other end is by circulation pipe and blending tank UNICOM, described blending tank is made up of support and tank body, wherein tank base is rack-mount, and be air tight structure, a main filling opening is established at described tank body top, at least one auxiliary liquid adding mouth and at least one gas returning port, bottom arranges a sewage draining exit and a liquid return hole, described auxiliary liquid adding mouth and liquid return hole are by circulation pipe and circulating pump UNICOM, described gas returning port is by airduct and exhaust outlet UNICOM, on described airduct, separately establish blower fan, described groove interior surface and cell body side liquid level line are all respectively established at least one pH value sensor below.

The utility model is simple in structure, floor space is little, and energy consumption is low, and the sour gas that acid solution is volatilized is collected thoroughly, the pollution of having avoided sour gas to cause, also increase the recycling to sour gas simultaneously, contributed to improve the stability of acid solution acidity, increased acid cycle simultaneously and driven function, overcome the drawback of acid strength skewness, improve acid solution utilization rate and pickling efficiency, extended the service life of acid solution, contributed to improve equipment environmental-protecting performance and reduced production cost.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

A kind of descaling bath as shown in Figure 1, formed by cell body 1 and groove lid 2, it is characterized in that: described cell body 1 is established sealing strip 3 with groove lid 2 contact-making surface places, at least one exhaust outlet 4 is established in the described cell body 1 above position of side liquid level line, a leakage fluid dram 5 and a filling opening 6 are established in bottom, described leakage fluid dram 5 and filling opening 6 spacing are 1/3-2/3 of cell body length, described leakage fluid dram 5 and filling opening 6 are separately connected with circulating pump 8 by circulation pipe 7 respectively, described circulating pump 8 other ends are by circulation pipe 7 and blending tank UNICOM, described blending tank is made up of support 9 and tank body 10, wherein tank body 10 bottoms are arranged on support 9, and be air tight structure, a main filling opening 11 is established at described tank body 10 tops, at least one auxiliary liquid adding mouth 12 and at least one gas returning port 13, bottom arranges a sewage draining exit 14 and a liquid return hole 15, described auxiliary liquid adding mouth 12 and liquid return hole 15 are by circulation pipe 7 and circulating pump 8 UNICOMs, described gas returning port 13 is by airduct 14 and exhaust outlet 4 UNICOMs, on described airduct 14, separately establish blower fan 16, described groove lid 2 inner surfaces and cell body 1 side liquid level line are all respectively established at least one pH value sensor 17 below.

When use, by pH value sensor, cell body inside acid solution and the sour gas that volatilizes are detected, wherein, after having sour gas to volatilize, drive sour gas is transferred in blending tank and stored temporarily by blower fan, when the acidity of acid solution changes or according to service condition timing, open circulating pump, the acid solution part of cell body is filled with in blending tank and then is circulated and flow in cell body, in blending tank, can dissolve the sour gas in blending tank on the one hand, increase the concentration of acid solution, force to increase on the other hand the mobility of acid solution in cell body, that in cell body, acid strength is evenly distributed.
