Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, and particularly relates to a printing and spraying waste gas treatment device. Background Art

[0002] Printing processes mainly include offset printing, intaglio printing and screen printing. The waste gas sources and emission methods of different processes are basically the same. The waste gas comes from the used ink and diluent, composite adhesives and equipment cleaning agents. Possible emission routes include solvent volatilization during ink mixing, ink solvent volatilization during printing, drying stage, composite process and equipment cleaning process, etc. The characteristics of the main organic volatile compounds emitted in the printing industry are low concentration and large air volume. It is necessary to use a waste gas treatment device to purify the waste gas generated by printing and spraying;

[0003] Chinese Patent Authorization Publication No. CN206823480U discloses a printing waste gas environmental protection treatment device, including a spray tower and an air filter. A fan is installed at the left end of the intake pipe. A plurality of spray pipes are installed on the outer wall of the bottom end of the horizontal pipe. A HEPA filter screen is installed on the left side inside the air filter. An activated carbon filter screen is installed on the right side of the HEPA filter screen. A molecular sieve filter screen is installed on the right side of the activated carbon filter screen. For this printing waste gas environmental protection treatment device, through the cooperation of the spray pipe, the fan and the air filter, the fan sucks the waste gas generated by the printing production line into the interior of the spray tower. Water molecules filter out the harmful substances soluble in water in the waste gas. The HEPA filter screen can filter out small particle harmful substances in the waste gas. The activated carbon filter screen can adsorb hydrocarbon-containing substances. The molecular sieve filter screen can adsorb aldehyde-containing substances. The purified air is discharged into the atmosphere through the chimney, which can filter all harmful substances and meet the emission standards, and can meet the user's needs. The above-mentioned existing technical solutions have the following deficiencies: This technical solution filters out harmful substances through the cooperation of the spray pipe, the fan and the air filter to meet the emission standards and meet the user's use requirements. However, the spraying angle of the spray component is relatively fixed, and it is easy to have the phenomenon of spraying dead angles. Therefore, we need to design a printing and spraying waste gas treatment device to solve the above-mentioned problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a printing and spraying waste gas treatment device to solve the problem of relatively fixed spraying angle proposed in the above background art.

[0005] To achieve the above object, the present utility model provides the following technical solution: A printing and spraying waste gas treatment device, including a base, on the top of the base is installed a waste gas treatment box, and at the top inside the waste gas treatment box is provided an air outlet. On one side of the waste gas treatment box is installed an air extraction pump, and the air outlet of the air extraction pump is connected to the inside of the waste gas treatment box through an air outlet pipe. Inside the waste gas treatment box is provided an installation seat, and inside the installation seat is provided a moving mechanism. The moving mechanism includes a receiving groove, and the receiving groove is provided inside the installation seat. At one end inside the receiving groove is installed a first motor, and the output end of the first motor is installed with a first connecting shaft. Outside the first connecting shaft is installed a turntable. Inside the receiving groove is installed a movable plate, and the movable plate is connected to the turntable through a connecting rod. On one side of the movable plate is installed an installation frame, and inside the installation frame is installed a second motor. The output end of the second motor is installed with a second connecting shaft, and outside the second connecting shaft is installed a first bevel gear. On one side of the installation frame is installed a hollow rotating shaft, and outside the hollow rotating shaft is installed a second bevel gear. The second bevel gear is meshed and connected with the first bevel gear. At the bottom inside the waste gas treatment box is installed a filter screen, and on one side of the filter screen are evenly installed sliders. Inside the waste gas treatment box are evenly provided sliding grooves, and the sliding grooves are all connected to the sliders.

[0006] When using a printing and spraying waste gas treatment device of this technical solution, by setting the moving mechanism to drive the movable plate to move up and down inside the receiving groove, the effect of being able to move up and down can be achieved. At the same time, by starting the second motor, the hollow rotating shaft and the connecting plate at the bottom can be driven to rotate, so that the spray head sprays while moving up and down and rotating, so that the purification liquid volatilizes more evenly.

[0007] Preferably, on one side of the waste gas treatment box is installed a water pump, and the water outlet of the water pump is connected to the inside of the hollow rotating shaft through a telescopic hose. At the bottom of the hollow rotating shaft is installed a connecting plate, and at the bottom of the connecting plate are evenly installed spray heads.

[0010] Preferably, the widths of the sliders are all equal to the widths of the sliding grooves, and the sliders and the sliding grooves are both symmetrically arranged about the central axis of the filter screen.

[0011] Compared with the prior art, the beneficial effects of the present utility model are: This printing and spraying waste gas treatment device not only realizes the function of adjustable spraying angle, but also realizes the function of facilitating the cleaning of the filter screen;

[0012] (1) By setting up a moving mechanism, starting the first motor drives the first connecting shaft to rotate, which further drives the turntable to rotate. Under the connection effect, it drives the movable plate to move up and down inside the receiving groove, thus achieving the effect of being able to move up and down. At the same time, by starting the second motor and under the meshing connection of the gears, it can drive the hollow rotating shaft and the connecting plate at the bottom to rotate, so that the spray head sprays while moving up and down and rotating, thus making the purification liquid volatilize more evenly to purify the harmful substances in the waste gas, effectively improving the purification performance of the waste gas treatment box;

[0013] (2) By installing a filter screen, large particle impurities in the waste gas can be filtered out to prevent them from affecting the subsequent purification work from proceeding smoothly. At the same time, through the sliding connection between the slider and the chute, the filter screen can be taken out from the inside of the waste gas treatment box regularly for cleaning and replacement, effectively extending the service life and use value of the filter screen.
