Description

Feeding and discharging moving device for acid washing or alkali washing closed room

Technical Field

The utility model relates to a mechanical moving mechanism, in particular to a feeding and discharging moving device for an acid washing or alkali washing closed room.

Background

At present, although a surface treatment workshop has great progress on process and equipment, the use of acid washing or alkali washing operation in the workshop is still difficult to avoid, so that the evaporation of acid liquor and alkali liquor is inevitably generated in the workshop; meanwhile, the workshops are generally designed in an open manner for facilitating production, so that acidic or alkaline gases or volatile matters are dissipated into the air, and great threats are caused to the health of workshop operators and the ecological environment. Such as acid washing process in a hot-dip galvanizing workshop, hydrochloric acid washing is generally adopted, and an acid washing tank inevitably generates acid mist and volatilization of hydrogen chloride, and the acid mist is diffused to the outside of the workshop in an irritant manner; in addition, the plating assistant salt film on the surface of the piece to be plated in the hot-dip galvanizing dip plating moment reacts violently with molten zinc to generate a large amount of irritant gas containing ammonia nitrogen and volatilize to the upper part of a workshop; these result in the operating environment of hot dip galvanizing workshop to be abominable, even adopt the top or lateral part convulsions to remove dust, also difficult to control in the workshop acid mist, the diffusion and the exorbitant escape of ammonia nitrogen smoke and dust, not only cause peripheral atmospheric environment to pollute, threaten operator's personal health more seriously. Engineers adopt a closed room mode to seal the pickling process to establish a pickling closed room, namely a so-called room-in-room structure, two side surfaces of the pickling closed room are completely sealed by transparent plates (such as acrylic plates and sunlight plates), two end surfaces of the pickling closed room are of a semi-closed structure formed by strip-shaped hanging curtains or flexible rolling curtains, and the hanging curtains or the rolling curtains are intermittently opened and closed to facilitate feeding and discharging; because the curtain or the roller shutter is still completely opened at the two end surfaces when opened, a large amount of irritant harmful gas is still generated to escape. Therefore, the complete sealing between the acid washing room and the alkali washing room and the complete control of the polluted gas are still the difficult points and the key points of the research in the industry, and are the problems to be solved in the industry.

Preferably, the projection of the partition of the utility model on the horizontal plane coincides with the centre line of the pool width.

Preferably, the feeding and discharging moving device is used in pairs in an acid cleaning room or an alkali cleaning room, and is respectively distributed at two ends of the acid cleaning closed room or the alkali cleaning closed room, wherein one end of the feeding and discharging moving device is used for feeding materials into the closed room, and the other end of the feeding and discharging moving device is used for discharging materials outwards from the closed room.

Compared with the prior art, the utility model has the following beneficial effects:

(1) the feeding and discharging moving device realizes the maximum sealing of an acidic or alkaline sealing chamber and prevents acid and alkali volatile gas or substances from escaping.

The feeding and discharging moving device disclosed by the utility model is based on a water seal principle that material water enters and exits under the liquid surface, the end surface of an acid cleaning or alkali cleaning closed room is closed to a large extent, only a small-size channel for moving a moving frame is reserved, and the channel is also semi-closed by a hanging curtain. Compared with the large-area curtain hanging or rolling curtain semi-sealing of the end surface of the traditional 'house-in-house', the sealing area of the end surface is obviously increased, and the sealing rate of an operating room is obviously improved; in addition, the material feeding and discharging moving device is used for feeding and discharging materials below the ground level of a workshop, a small-size channel with a freely moving frame is close to the ground level, and volatile substances are usually volatilized upwards from the notch of the groove body; therefore, the technical effect of the utility model realizes the maximum sealing of the acid or alkaline sealing room, prevents the escape of acid and alkali volatile gas or substances, and has important engineering significance for preventing and controlling the atmospheric pollution of the acid pickling workshop or the alkali car washing room.

(2) The feeding and discharging mobile device is simple in structure, convenient to use and suitable for emission reduction control of old workshops.

The feeding and discharging moving device conveniently finishes feeding into the closed room and discharging outwards from the closed room by reasonably designing the sizes and the positions of the partition, the moving frame and the water pool, and simultaneously realizes the maximum sealing of the closed room. Aiming at the pickling or degreasing process of an old hot-dip galvanizing workshop or an electroplating workshop, the external structure of the workshop is not required to be changed, and the installation and operation of the feeding and discharging mobile device are met only by sealing the periphery of the pickling process or the alkaline washing process, reserving a running channel of a mobile frame at two end faces and adding a water pool (the tail end of the pickling process or the alkaline washing process is at least provided with a rinsing tank). Therefore, the feeding and discharging mobile device is simple in structure, convenient to use, low in cost investment and very suitable for energy conservation and emission reduction transformation of an acid washing process and an alkali washing process of an old workshop.
