Description

An automatic control device for continuous high-pressure air purge

technical field

The utility model relates to a continuous-drawing pretreatment blowing device for steel cord production, in particular to an automatic control device for continuous-drawing high-pressure wind blowing, which belongs to the technical field of mechanical devices.

Background technique

In the production of steel cord, during the pretreatment process of the wire rod in the first wire drawing process, it is necessary to wash the wire rod with high-pressure water, chemical salt pickling, cold water washing, hot water washing, and boron coating; There is a high-pressure air blowing between different pretreatment tanks to ensure that the steel wire will not bring the solution from the upper tank to the next pretreatment tank.

Due to the particularity of production, the machine tool will stop, such as unloading, mold change, maintenance, etc. Through actual tracking statistics, the production efficiency of continuous pulling is about 85%, and our high-pressure air blowing is always blowing, Regardless of whether the machine tool is running or not, we actually waste 15% of the gas consumption in one day; extensive control leads to a huge waste of resources.

Utility model content

In order to solve the deficiencies of the existing technology, the purpose of this utility model is to provide an automatic control device for continuous high-pressure air purge, which can flexibly control whether high-pressure air purges in combination with actual production, reduce the amount of high-pressure air, and effectively save resources.

In order to achieve the above object, the utility model adopts the following technical solutions:

An automatic control device for continuous high-pressure air purge, including a solenoid valve and a pneumatic angle valve, the solenoid valve is controlled by a machine tool system, and the solenoid valve is connected to the pneumatic angle valve through a high-pressure air pipeline, and the pneumatic angle valve Set on the high-pressure air supply pipeline.

Furthermore, the pneumatic angle valve is a stainless steel pneumatic angle seat valve, which is sensitive in response and accurate in action, and can be adapted to frequent start-up in a short period of time.

Further, a plurality of purge air supply pipes are arranged in parallel on the high-pressure air supply pipe, and the multiple purge air supply pipes respectively correspond to positions that need to be purged.

Further, the purge air supply pipeline is provided with a manual control valve, which can manually control whether the purge air supply pipeline is blown or not.

The utility model is beneficial in that: combined with actual production, it can flexibly control whether the high-pressure air blows or not, greatly reducing the consumption of high-pressure air, reducing the number of air compressors in operation, saving more than 15%, and effectively saving resources.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is made concrete introduction.

Fig. 1 is a structural representation of the utility model;

As shown in Figure 1: This embodiment is an automatic control device for continuous high-pressure air purge, including a solenoid valve 2 and a single-acting pneumatic angle valve. The solenoid valve 2 is controlled by the machine tool system, and the solenoid valve 2 passes through the high-pressure air pipeline. 3. Connect with the pneumatic angle valve, which is set on the high-pressure air supply pipeline 5; in this embodiment, the pneumatic angle valve is a stainless steel pneumatic angle seat valve 4, which has sensitive response, accurate action, and can adapt to frequent start-up in a short period of time and other advantages; on the high-pressure wind air supply pipeline 5, a plurality of purge air supply pipelines 6 are arranged in parallel, and a plurality of purge air supply pipelines 6 respectively correspond to the positions that need to be purged; each purge air supply pipeline 6 is provided with The manual control valve 7 can manually control whether the purge gas supply pipeline 6 is blown.

When the machine tool 1 is running, the machine tool system gives the solenoid valve 2 a start signal, and the solenoid valve 2 opens the stainless steel pneumatic angle seat valve 4 through the high-pressure air pipeline 3, and then opens the high-pressure air supply pipeline 5, and the high-pressure air supply pipeline 5 is connected in parallel A plurality of purge air supply pipelines 6 are set corresponding to the high-pressure air purge mode for each groove body of the pretreatment steel wire. When the machine tool 1 stops running, the machine tool system sends a stop signal to the solenoid valve 2, and the solenoid valve 2 passes through the high-pressure air pipeline 3 Close the stainless steel pneumatic angle seat valve 4, and then close the high-pressure air supply pipeline 5, and the multiple purge air supply pipelines 6 arranged in parallel on the high-pressure air supply pipeline 5 close the high-pressure air purge mode to realize machine tool movement and purge movement. The automatic control mode of machine tool stop and purge closed; in the process of opening the high-pressure purge mode, if one of the tanks of the pretreated steel wire does not need to be purged, the purge gas supply pipe 6 corresponding to the tank The provided manual control valve 7 controls its closing, which effectively saves resources and does not affect the purging operation of other purging air supply pipelines 6 .

When the solenoid valve 2 is running on the machine tool 1, the machine tool 1 gives a working signal, and the solenoid valve 2 opens the high-pressure air pipeline 3, and the connection of the high-pressure air pipeline 3 indirectly controls the stainless steel pneumatic angle seat valve 4 to open the high-pressure air supply. Gas pipeline 5, and then opened the purge air supply pipeline 6 on each tank body to enter the purging working state, and blow off the residual solution of the previous tank body brought out on the running steel wire to meet the process control requirements.

Combined with actual production, the utility model flexibly controls whether the high-pressure air is blown or not, greatly reduces the consumption of high-pressure air, reduces the number of air compressors in operation, saves more than 15%, and effectively saves resources.
