Description

Technical Field

[0001] The invention relates to the field of water curtain cabinets, in particular to spray purification equipment. Background Art

[0002] Water curtain cabinet is an environmental protection equipment used for waste paint and waste gas treatment. It is mainly used for paint spraying waste gas treatment in paint spraying assembly line workshops of various industries. It has the advantages of simple operation, stable use and safety. The characteristic of water curtain cabinet is that it can directly hit the remaining paint powder during paint spraying into the water pool or on the water curtain surface, and the odor generated during paint spraying and the small amount of unabsorbed paint powder are filtered through multiple layers of water curtains and discharged to the outside of the paint spraying room through the exhaust fan, thereby purifying the paint spraying working environment and protecting personal health, and can also enhance the smoothness of the surface of the painted workpiece.

[0003] When the existing water curtain cabinet absorbs the paint mist of the spray paint, since the water used in the water curtain cabinet is water at room temperature, when the water temperature is low, the viscosity of the water is low, and the water is easily separated when flowing up and down the curtain wall, resulting in a gap in the water curtain, which reduces the absorption efficiency of the paint mist. Moreover, when the water temperature is low, when the water on the water curtain drops into the water curtain cabinet, it will splash water. Since part of the absorbed paint mist will float on the water, as the water splashes, the harmful substances in the paint mist will splash with the water droplets, affecting the current environment. When the water curtain cabinet is in operation, the air in the water curtain cabinet is extracted by the exhaust fan. However, some harmful gases in the paint mist that are difficult to dissolve in water will also be discharged, polluting the external environment.

[0015] Compared with the prior art, the present invention provides a spray purification device with the following beneficial effects: 1. This spray purification equipment is provided with a cleaning mechanism. Water is pumped from the water pool through a water suction pipe, and then flows into the slot through a drain pipe and a water distribution pipe. The water then flows down from the front side of the slot to form a water curtain. The water curtain flows into the bottom of the frame. At this time, the water is pumped into the mixing barrel through the water guide pipe for chemical treatment, and then flows into the water pool through the water outlet pipe. The water is filtered through multiple filters to clean the water, and then the water is continuously pumped through the water suction pipe to form a water cycle, so that the paint mist impurities absorbed in the water can be cleaned. At the same time, the air in the frame is extracted by the fan, and the gas insoluble in water in the paint mist is pumped into the mixing barrel through the air guide pipe, so that the gas is fully mixed with the water in the mixing barrel.

[0016] 2. This spray purification equipment is provided with a heat preservation ring and a water supply plate. On the one hand, the water is heated up by the heat preservation ring during the water suction pipe pumping process. After the temperature rises, the viscosity of the water increases. In the process of forming a water curtain, the probability of a gap in the water curtain is reduced. On the other hand, the first two-way threaded rod is driven to rotate by the first motor, and the first two-way threaded rod drives the two threaded blocks to move relative to each other. The two threaded blocks drive the water supply plate to move through two deflection plates until it is in a suitable position. At this time, the water on the water curtain first flows onto the water supply plate. When the water supply plate accumulates a certain amount of water, the water continues to flow down along the outer wall of the water supply plate to re-form a water curtain, thereby avoiding the separation of the water curtain due to insufficient viscosity.

[0017] 3. This kind of spray purification equipment is provided with a curtain mechanism, which drives the second bidirectional threaded rod to rotate through the second motor, and the second bidirectional threaded rod drives the two partitions to move until they are in a suitable position. When the object to be painted is small, it is only necessary to adjust the corresponding partition position and open the solenoid valve corresponding to the water curtain at the same time to form a local water curtain to absorb the paint mist. At the same time, the partition divides the water curtain into multiple working areas, and multiple workpieces can be painted at the same time, which improves the work efficiency of painting. When the object to be painted is large, the partition is adjusted to both sides, and the three solenoid valves are opened at the same time to make the water curtain generated in the middle wide enough, which is sufficient to absorb the paint mist generated when spraying large workpieces, and the paint mist absorption effect is better.

[0018] 4. This spray purification equipment is provided with a guide plate. When the water curtain flows down, the water flow is guided by the guide plate and flows directly into the bottom of the frame along the guide plate without generating splashes, thereby avoiding splashing of harmful substances in the water and polluting the working environment.

[0019] The present invention can increase the temperature of water, increase the viscosity of water, avoid gaps in the water curtain, have a better effect on the absorption and treatment of paint mist, and improve the work efficiency of painting without polluting the working environment.

At this time, the water on the water curtain first flows onto the water replenishment plate 5. When the water replenishment plate 5 accumulates a certain amount of water, the water continues to flow down along the outer wall of the water replenishment plate 5 to re-form a water curtain, thereby avoiding the situation where the water curtain is separated due to insufficient viscosity.

[0025] In order to spray paint on multiple workpieces at the same time and improve the painting efficiency, a curtain partition mechanism 7 is set to separate the curtain wall 2.

When the object to be painted is small, it is only necessary to adjust the position of the corresponding partition 8 and open the solenoid valve 14 corresponding to the water curtain at the same time to form a local water curtain to absorb the paint mist. At the same time, the partition 8 divides the water curtain into multiple working areas, and multiple workpieces can be painted at the same time, thereby improving the efficiency of painting. When the object to be painted is large, the partition 8 is adjusted to both sides, and the three solenoid valves 14 are opened at the same time to make the water curtain generated in the middle wide enough, which is sufficient to absorb the generated paint mist when spraying large workpieces, and the paint mist absorption effect is better.

[0026] After the paint mist is absorbed, the water needs to be cleaned and purified, so a cleaning mechanism 16 is set up to clean the sewage. The cleaning mechanism 16 includes three stirring barrels 17 arranged on the rear side of the curtain wall 2. It should be noted that the stirring barrel 17 is provided with a feeding port to facilitate the addition of chemical agents to treat the water. The stirring barrel 17 is fixedly installed with the frame 1, and a water diversion pipe 18 is provided above the stirring barrel 17. It should be noted that one end of the water diversion pipe 18 located inside the frame 1 is connected to a water pump for pumping water into the stirring barrel 17. The water diversion pipe 18 extends to the bottom of the frame 1. An air guide pipe 19 is provided through the frame 1. The air guide pipe 19 is U-shaped. The air guide pipe 19 is fixedly connected to the lower ends of the three stirring barrels 17. An air outlet pipe 20 is provided at the upper end of the stirring barrel 17. The air outlet pipe 20 is connected to the frame The frame 1 is connected to the outside of the frame 1, a one-way valve is provided in the air duct 19, a fan 22 is installed in the frame 1, the fan 22 is matched with the air duct 19, a water pool 23 is installed outside the frame 1, a plurality of filters 24 are installed in the water pool 23, and the lower ends of the three mixing barrels 17 are all equipped with water outlet pipes 25, and the ends of the three water outlet pipes 25 away from the mixing barrel 17 are all extended to one side of the water pool 23, and a water suction pipe 26 is inserted on the other side of the water pool 23. It should be noted that the water suction pipe 26 and the water outlet pipe 25 are respectively located on both sides of the water pool 23. It should be noted that the end of the water suction pipe 26 located in the water pool is connected to a water pump. Specifically, the water suction pipe 26 is coated with an insulation ring 27, and a temperature regulator is embedded in the insulation ring 27. The end of the water suction pipe 26 away from the water pool 23 is connected to the drain pipe 12.

[0027] Through the above technical features: when absorbing and purifying the paint mist, water is pumped from the water pool through the water suction pipe 26, and then flows into the slot 9 through the water discharge pipe 12 and the water distribution pipe 11. The water then flows down from the front side of the slot 9 to form a water curtain, which absorbs the paint mist and flows into the bottom of the frame 1. At this time, the water is pumped into the mixing barrel 17 through the water guide pipe 18 for chemical treatment, and then flows into the water pool 23 through the water outlet pipe 25, and is filtered through multiple filter screens 24 to clean the water. After the cleaning is completed, it continues to pass through The water suction pipe 26 draws water to form a water circulation, which can clean the paint mist impurities absorbed in the water. At the same time, the air in the frame 1 is extracted through the fan 22. During the extraction process, a negative pressure is formed in the gap on the lower side of the curtain wall 2. At this time, the gas that is insoluble in water is extracted from the gap and is drawn into the mixing barrel 17 through the air guide pipe 19, so that the gas is fully mixed with the water in the mixing barrel 17. After the mixing is completed, the gas is discharged from the air outlet pipe 20, so that the gas that is insoluble in water can be absorbed and purified, and the effect of absorbing and treating the paint mist is better.

[0028] Working principle: Water circulation: Water is pumped from the pool through the suction pipe 26, and then flows into the slot 9 through the drain pipe 12 and the water distribution pipe 11. The water then flows down from the front side of the slot 9 to form a water curtain, which flows into the bottom of the frame 1. At this time, the water is pumped into the mixing barrel 17 through the water diversion pipe 18, and then flows into the pool 23 through the outlet pipe 25, and then continues to be pumped through the suction pipe 26 to form a water circulation.

[0029] Absorb and treat paint mist: When spraying paint, the paint mist that is easily soluble in water dissolves with the water in the water curtain, and the water that absorbs the paint mist falls into the bottom of the frame 1. The water drawn into the mixing barrel 17 is stirred and purified through chemical treatment. After purification, it is introduced into the water pool 23 through the outlet pipe. The water in the water pool 23 is filtered through the filter screen 24 to complete the water purification.

[0030] Absorb and treat the insoluble gas in the paint mist: the air in the frame 1 is extracted by the fan 22. During the extraction process, a negative pressure is formed in the gap at the bottom of the curtain wall 2. At this time, the insoluble gas in water is extracted from the gap and is drawn into the mixing barrel 17 through the air guide pipe 19, so that the gas is fully mixed with the water in the mixing barrel 17. After the mixing is completed, the gas is discharged from the air outlet pipe 20, and the insoluble gas in water can be absorbed and purified.

[0031] Adjustment of the number and width of water curtains: when spraying paint on multiple workpieces, the second motor 32 drives the second bidirectional threaded rod 21 to rotate, and the second bidirectional threaded rod 21 drives the two partitions 8 to move until they are in a suitable position. When the objects to be painted are small, it is only necessary to adjust the position of the corresponding partition 8 and open the solenoid valve 14 corresponding to the water curtain to form a local water curtain to absorb the paint mist. At the same time, the partition 8 divides the water curtain into multiple working areas, so that multiple workpieces can be sprayed with paint; when spraying paint on a single large workpiece, adjust the partition 8 to both sides and open the three solenoid valves 14 at the same time so that the water curtain generated in the middle is wide enough to spray paint the large workpiece.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
