A kind of plating shop chemical tank with the frequency conversion air intake device
Technical field
The utility model relates to a kind of plating shop chemical tank, and particularly a kind of plating shop chemical tank with the frequency conversion air intake device belongs to technical field of plating equipment.
Background technology
At present, plating shop adopts vacuum fan uninterrupted duty in continuous 24 hours usually, and is in maximum suction air volume operation all the time; The shortcoming of this design: 1) electric quantity consumption is big; 2) noise is big; 3) the excessive pollution outside atmosphere of exhaust air rate; 4) uninterrupted exhausting makes the workshop be in negative pressure state, accelerates the tank liquor evaporation.
The utility model content
The utility model purpose be proposed in order to overcome the deficiencies in the prior art particularly a kind of can energy efficient, the big I of air quantity regulates, improves the workshop air quality according to actual user mode, the plating shop chemical tank of reduction noise band frequency conversion air intake device.
For achieving the above object, the technical solution adopted in the utility model is: a kind of plating shop chemical tank with the frequency conversion air intake device comprises chemical tank, main aspiration channel, little aspiration channel, baffle plate, frequency conversion suction fan; The upper end of described little aspiration channel is stretched in the chemical tank; The lower end of described little aspiration channel is connected with main aspiration channel; Described baffle plate is arranged on the ingress of little aspiration channel; Described frequency conversion suction fan is arranged on outside the chemical workshop, is communicated with main aspiration channel.
Preferably, described baffle plate is " eight " font, and turning axle is arranged on its medullary ray.
Preferably, the air outlet of described frequency conversion suction fan is communicated with the waste gas spray column; Whether be provided with waste gas near the outlet of described waste gas spray column and detect the hole, it is up to standard to be used for detecting off gas treatment.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
The plating shop chemical tank of band frequency conversion air intake device of the present utility model, noise in workshop reduces behind the use frequency conversion suction fan, and energy consumption reduces; Take toxic gas away by regulating air quantity targetedly, make the workshop air quality pure and fresh, reduce pollution simultaneously the workshop outside atmosphere; In addition, because the groove lid is closed as a rule, vacuum fan just is in the state of low cruise, and the exhausting amount has reduced, and the steam output of tank liquor just reduces, and can greatly prolong the work-ing life of tank liquor, thereby obtain the purpose of controlling cost.

Embodiment
Below in conjunction with accompanying drawing the utility model is described.
Be depicted as a kind of plating shop chemical tank described in the utility model as accompanying drawing 1,2, comprise chemical tank 1, main aspiration channel 2, little aspiration channel 3, baffle plate 4, frequency conversion suction fan 5 with the frequency conversion air intake device; The upper end of described little aspiration channel 3 is stretched in the chemical tank 1; The lower end of described little aspiration channel 3 is connected with main aspiration channel 2; Described baffle plate 4 is arranged on the ingress of little aspiration channel 3; Described frequency conversion suction fan 5 is arranged on outside the chemical workshop 8, is communicated with main aspiration channel 2; Described baffle plate 4 is " eight " font, and turning axle is arranged on its medullary ray; The air outlet of described frequency conversion suction fan 5 is communicated with waste gas spray column 6; Whether be provided with waste gas near the outlet of described waste gas spray column 6 and detect hole 7, it is up to standard to be used for detecting off gas treatment.
Chemical tank 1 cell body both sides are provided with the little aspiration channel 3 of sectional type stainless steel, and volume damper and main aspiration channel 2 UNICOMs are arranged; The air suction inlet of little aspiration channel 3 is positioned at chemical tank 1 both sides, upper end or all around.Main aspiration channel 2 adopts micro-pressure sensors control, and when the groove lid was closed, negative pressure increased in the groove, and frequency conversion suction fan 5 operating frequencies diminish, and air quantity is reduced to minimum, makes the pollution with dust in the volatilization that reduces tank liquor and the air of the negative pressure that keeps small in the groove; When the groove lid is opened, provide signal by PLC, frequency is elevated to certain numerical value, and the exhausting amount reaches maximum value, and toxic gas all is drawn in the waste gas spray column and handles to guarantee.If open a plurality of groove lids, frequency progressively classification improves.Can greatly improve operating environment, make the degree with fresh air in the workshop reach outdoor standard.Because the groove lid in most cases; all be that closure state (comprises when workpiece is handled; the groove lid also can be closed); therefore frequency conversion suction fan 5 is low cruise as a rule; effectively conservation of power can reach more than 90%; reduce the volatilization of tank liquor simultaneously, reduce the noise of blower fan, greatly prolong work-ing life of equipment, protection operator's safety and Health and workshop appliance are not corroded.
In addition, waste gas spray column 6 designs by maximum exhausted air quantity, and 90% all is the closed situation of groove lid during actual motion, and the exhausted air quantity of generation is significantly less than original design flow.Therefore treatment effect is splendid, can be reduced to minimum to atmospheric pollution.Controlled the total amount that waste gas produces from the source.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
The plating shop chemical tank of band frequency conversion air intake device of the present utility model, noise in workshop reduces behind the use frequency conversion suction fan, and energy consumption reduces; Take toxic gas away by regulating air quantity targetedly, make the workshop air quality pure and fresh, reduce pollution simultaneously the workshop outside atmosphere; In addition, because the groove lid is closed as a rule, vacuum fan just is in the state of low cruise, and the exhausting amount has reduced, and the steam output of tank liquor just reduces, and can greatly prolong the work-ing life of tank liquor, thereby obtain the purpose of controlling cost.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
