Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment devices, in particular to a detectable waste gas treatment device used in a paint production room. Background Art

[0002] The paint production workshop will be mixed with organic waste gases such as benzene, alcohols, and alkanes. Therefore, in order to ensure the air quality in the paint workshop, it is necessary to use waste gas treatment equipment to treat the paint waste gas.

[0003] For example, the announcement number is: CN216879924U (named as an exhaust gas treatment device for automatic spraying production), which includes: a paint spraying beam limiting structure, which includes a paint spraying hood and a paint spraying head extension hole that penetrates and is opened on the rear surface of the paint spraying hood; two air collecting adjustment structures, which are symmetrically and movably assembled on the upper and lower surfaces of the paint spraying hood; each of the air collecting adjustment structures includes an electric telescopic rod movably connected to the outer inclined surface of the paint spraying hood, an air collecting hood movably connected to the output end of the electric telescopic rod, and two columns movably connected to one side of the outer surface of the air collecting hood and facing the paint spraying hood; the two columns are located on the rear side of the electric telescopic rod and are fixedly installed on the paint spraying hood. The invention relates to a paint spraying hood, wherein the air collecting hood is on the upper surface of the paint spraying hood; the opening of the air collecting hood is oriented in the same direction as the opening of the paint spraying hood; and an air suction structure is fixedly installed on the rear surface of each of the air collecting hoods, each of the air suction structures comprises a plurality of centrifugal fans fixedly connected to the rear surface of the air collecting hood and an air guide hood fixedly connected to the output ends of the plurality of centrifugal fans. The paint spraying limiting structure formed by the paint spraying hood and the extension hole of the paint spraying head can make the automatic spraying tool extend and limit to the paint spraying hood for spraying. The structural setting of the trumpet-shaped paint spraying hood can improve the bundling of the spraying of the spraying tool placed therein, thereby reducing the overflow area of ​​the paint molecules, and further improving the collection of the subsequent spraying waste gas.

[0004] The above-mentioned paint waste gas treatment device extracts the paint waste gas through the centrifugal fan structure, but only extraction can only discharge the paint waste gas. The discharged paint waste gas will still cause environmental pollution, resulting in the problem of poor environmental protection of the device. For this reason, we provide a detectable waste gas treatment device for a paint production room. Utility Model Content

[0005] The purpose of the utility model is to provide a detectable exhaust gas treatment device for a paint production room, so as to solve the problem that the existing paint exhaust gas treatment device proposed in the above background technology extracts the paint exhaust gas through the centrifugal fan structure, but only extracts and discharges only the paint exhaust gas, and the discharged paint exhaust gas still causes environmental pollution, resulting in the poor environmental protection of the device.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a detectable waste gas treatment device for a paint production room, comprising a device wall panel, a ventilation fan is arranged on the inner side of the device wall panel, an exhaust pipe is arranged on the air outlet end of the ventilation fan, the exhaust pipe penetrates and extends to the outside of the device wall panel, a purified water tank is arranged below the exhaust pipe, and a drain valve is arranged on the outer wall of the purified water tank;

[0010] The connecting disk is installed at one end of the end guide tube, and a supporting disk is arranged on one side of the connecting disk. A driving motor is fixed on the supporting disk by screws, and a fan blade is arranged on the output shaft of the driving motor.

[0011] Preferably, a connecting rod is provided between the connecting plate and the supporting plate, and two ends of the connecting rod are respectively welded to the connecting plate and the supporting plate.

[0014] Preferably, six assembly holes are provided at the connection position between the built-in disk and the flange, and the six assembly holes are all integrated with the built-in disk.

[0015] Preferably, an extension conduit is provided at the bottom of the exhaust pipe through threaded assembly, and the extension conduit is inserted into the water inside the purified water tank.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model drives the fan blades to rotate through a driving motor, so that the fan blades blow the air in the paint workshop into the interior of the end duct, and detects and processes the air through a paint gas detector. The paint gas detector adopts an imported catalytic combustion sensor and a natural diffusion detection principle, and is used in conjunction with an alarm controller to detect and display the paint concentration and provide an audible and visual alarm reminder after the concentration exceeds the standard. After the alarm reminder, the connecting plate and the supporting plate are removed, and the ventilation fan is turned on, so that the ventilation fan draws out the air in the paint workshop. After adsorption and filtration by the activated carbon filter, the exhaust gas is injected into the water in the purified water tank through the exhaust pipe and the extension duct. Finally, the gas is suppressed and filtered by water and discharged from the water in the form of bubbles and enters the outdoor air, thereby achieving the purpose of dual purification of the paint exhaust gas. The existing paint exhaust gas treatment device overcomes the problem that the paint exhaust gas is extracted by the centrifugal fan structure, but only extraction can only exhaust the paint exhaust gas, and the exhausted paint exhaust gas will still cause environmental pollution, resulting in poor environmental protection of the device.

[0018] 2. After the paint waste gas is extracted, negative pressure is generated in the paint workshop, allowing outdoor air to enter through the air intake groove, thereby achieving the purpose of filling the paint workshop air and realizing ventilation of the paint workshop.
