Description
Technical field
The utility model relates to a kind of container surface weld seam and handles the two jars of special-purpose continuous sand-blasting machines of multiple gun.
Background technology
At present, mostly the two jars of multiple gun sand-blasting machines that container plant uses are to be divided in the tank body two warehouses, and following storehouse air inlet and the shared valve of middle dried mushroom head; Realize continuous sandblast operation, in use, when following storehouse adds sand; Upper and lower storehouse air-flow mixes, and causes a jar internal gas pressure fluctuation, and the air pressure in the sand-spraying pot is unstable; Cause the decline of sandblast quality, thereby can't satisfy the requirement that streamline is produced.Behind the workpiece of this kind sand-blasting machine sandblast, also need prepare the moving spray gun of leader in addition and fill spray, increase people's force intensity, time-consuming, production efficiency is low.
The utility model content
The purpose of the utility model is to provide a kind of modified the two jars of continuous sand-blasting machines of multiple gun, controls through adopting the microcomputer computer, to simplify the operation and to improve the stable and reliability of its work, avoids air-flow pulse sandblast.Thereby realize the purpose of the utility model.
The technical problem that the utility model solved can adopt following technical scheme to realize:
Two jars of continuous sand-blasting machines of multiple gun of a kind of modified; Comprise jar, following jar and be positioned between the two the centre head valve of pestering; Said following jar is equipped with the two-way barrier film that is used to shake out shake out valve and pneumatic operated valve, it is characterized in that, said go up jar with following jar be provided with independently intake valve and air bleeding valve; The last jar of intake valve with following jar is communicated in total air inlet gate valve; Said top of going up jar is equipped with jar a last charge level detector, and following jar bottom is equipped with down a jar following charge level detector, last jar and following jar intake valve, upward jar upward charge level detector with following jar under charge level detector all be connected with the micro computer processing unit.
In an embodiment of the utility model, shake out valve and pneumatic operated valve, intake valve and air bleeding valve of said two-way barrier film is normally open valve.
In an embodiment of the utility model, the said jar of going up also is equipped with safety valve with following jar.
The beneficial effect of the utility model is: adopted the design of micro computer processing unit module; It is various to have changed original electrical equipment, and control circuit is complicated, and binding post is more; Fault rate is high; Overhaul difficult problems, improved the reliability of electric control system simultaneously, reached and improved the service efficiency of equipment, the purpose that simplifies the operation.
Description of drawings
Fig. 1 is the structural representation of the described two jars of continuous sand-blasting machines of multiple gun of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with the specific embodiment, further set forth the utility model.
As shown in Figure 1; Two jars of continuous sand-blasting machines of multiple gun of the described a kind of modified of the utility model; Comprise jar, following jar and be positioned between the two the centre head valve 9 of pestering; Said following jar is equipped with the two-way barrier film that is used to shake out shake out valve 11 and pneumatic operated valve 12, and the said jar of going up is provided with upper inlet valve 4 and last air bleeding valve 6, and play jar is provided with lower inlet valve 13 and following air bleeding valve 15; The last jar of intake valve with following jar is communicated in total air inlet gate valve 14; Said top of going up jar is equipped with jar a last charge level detector 3, and following jar bottom is equipped with down a jar following charge level detector 10, last jar and following jar intake valve, upward jar upward charge level detector with following jar under charge level detector all be connected with the micro computer processing unit; Described sand valve all is connected with micro computer processing unit output module with air bleeding valve warp and pneumatic operated valve, by the switching of micro computer processing unit according to the above-mentioned sand valve of material level signal controlling and the air bleeding valve warp and the intake valve of level-sensing device input.
Two jars of multiple gun sand-blasting machines of the utility model have following beneficial effect:
1. Automatic Control is simple to operate
Charge level detector (abbreviation sensors A) on upper end on the sand jar has on one jar, the following pot bottom of sand jar has one following jar time charge level detector (abbreviation sensor B).
When closing when not having signal, " B " close jar dried mushroom head valve and last jar of air bleeding valve, after a certain amount of time (this time can be provided with), and after upper and lower jar of air pressure reaches balance, middle dried mushroom head valve action, last jar of downward jar adds sand.Add sand and finish (this time can be provided with).Middle dried mushroom head valve is closed, and last jar of air bleeding valve opened, and goes up the canister incoming gas valve simultaneously and closes, and after a certain amount of time, last jar of dried mushroom head opened.Go up simultaneously jar and add the sand valve and open and jar begin to add sand and signal is arranged, close and close jar dried mushroom head valve and wait for that the jar of going up jar downwards next time adds sand and circulates until the A sensor.
2. adopt micro computer processing unit centralized Control and make sand valve, intake valve and air bleeding valve all adopt normally open valve; Do not exist system to cut off the power supply suddenly; Lose detection signal or system dies suddenly, lose the power source incident of valve member after, the systemic breakdown situation; Reduced labor strength, working service is convenient and simple.
3. by micro computer processing unit centralized Control, simplify circuit, reduce vigour part and circuit, the equipment working stability is reliable, and fault rate is low.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
