Description

Technical Field

[0001] This utility model relates to the technical field of powder coating testing equipment, and in particular to a salt spray tester for powder coating testing. Background Technology

[0002] Powder coatings play a role in preventing corrosion of metals and other materials, thus protecting the service life of non-ferrous metals. During the production of electrostatic powder coatings, salt spray tests are conducted, which involves using a smoke tester. The salt spray test is an environmental test that uses artificial smoke environment conditions created by the salt spray tester to assess the corrosion resistance of products or metal materials.

[0003] In existing technologies, such as the automatic air supply system for a salt spray test chamber in a powder coating laboratory disclosed in patent publication number CN211206187U, the system is characterized by comprising a first air supply source and a second air supply source, which are connected to a dispersed air supply component within the salt spray chamber via a pressure regulating valve. The first air supply source uses a large production air compressor, while the second air supply source uses a small laboratory air compressor. The pressure regulating valve has two valve chambers internally separated by a pneumatic opening and closing mechanism. The first valve chamber is connected to the first air supply source via a first air source inlet and pipeline, and the second valve chamber is connected to the second air supply source via a second air source inlet and pipeline. An air outlet is located on the side of the first valve chamber opposite to the first air source inlet, and this outlet is connected to a saturator via a pipeline. The opening end of the pneumatic opening and closing mechanism is located within the first valve chamber. This invention simplifies operation and switching, reduces equipment maintenance frequency, saves energy, and significantly reduces production costs.

[0004] However, existing salt spray testing machines require the salt spray to be discharged from inside the machine after it is generated when conducting salt spray tests on powder coatings. Since the salt spray contains acidic gases, direct discharge will cause environmental pollution. Furthermore, the contact effect between the salt spray and the powder coating is not good during the salt spray test. Therefore, the above problems need to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a salt spray tester for powder coating testing, which has the effect of purifying salt spray.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a salt spray tester for powder coating testing, comprising a body, a purification chamber fixedly connected to the outside of the body, a three-way pipe fixedly connected to the top of the purification chamber, the three-way pipe extending into the interior of the body, an air pump fixedly connected to the middle of the three-way pipe, a spray pipe fixedly connected to the interior of the purification chamber, an atomizing nozzle fixedly connected to one end of the spray pipe, an exhaust port opened on the outside of the purification chamber, a wind hood fixedly connected inside the exhaust port, a fan fixedly installed inside the wind hood, a block fixedly connected to the inner wall of the purification chamber, an isolation plate overlapping the top of the block, a drain hole opened inside the isolation plate, a wastewater tank fixedly connected to the inner bottom wall of the purification chamber, a drain pipe fixedly connected inside the wastewater tank, a valve installed inside the drain pipe, an activated carbon mesh fixedly connected inside the exhaust port, and activated carbon installed inside the activated carbon mesh.

The spray pipe is connected to the water source, and the water pump draws water into the spray pipe. The water is sprayed into the purification chamber through the atomizing nozzle, thus spraying the salt spray inside the purification chamber to remove acidic gases. The wastewater enters the wastewater tank through the drainage holes inside the isolation plate for storage. Then, the operator starts the fan, which draws the salt spray inside the purification chamber into the hood. The activated carbon mesh is placed inside the exhaust port. Before entering the hood, the smoke is purified by the activated carbon inside the mesh, which adsorbs impurities inside the salt spray. The smoke is then discharged through the hood, thus enabling the device to purify the salt spray and reduce the emission of harmful gases during the discharge process.

[0008] A further feature of this invention is that a horizontal shaft is fixedly connected inside the body, and a cover is fitted onto the middle of the horizontal shaft.

[0009] By adopting the above technical solution, the cover is rotatably connected to the inside of the machine body via a horizontal shaft. The machine body is closed by the cover, and the powder coating is placed into the inside of the machine body when the cover is opened.

[0010] A further feature of this invention is that the cover is transparent, and a handle is fixedly connected to the outside of the cover.

[0011] By adopting the above technical solution and using a transparent cover, staff can observe the testing conditions inside the machine in a timely manner.

[0012] A further feature of this invention is that motors are fixedly installed on both sides of the exterior of the machine body, and a locking block is fixedly connected to the output end of the motor, with a powder cylinder locked inside the locking block.

[0013] By adopting the above technical solution, the powder coating is filled into the inside of the powder cylinder, and then the powder cylinder is clamped into the inside of the clamping block. The motor is started, so that the motor drives the powder cylinder to rotate. The rotation of the powder cylinder can make the powder coating move, so that the salt spray can fully contact the powder coating and improve the test effect.

[0014] A further feature of this invention is that the number of powder cylinders is two, and the two powder cylinders are symmetrical to each other.

[0015] By adopting the above technical solution and setting up two powder cylinders, it is possible to conduct simultaneous tests on multiple batches of powder coatings.

[0016] A further feature of this invention is that a motor housing is fixedly connected to the outside of the machine body, and the motor is located inside the motor housing.

[0017] By adopting the above technical solution, the motor housing encloses the motor, thereby protecting it.

[0018] A further feature of this invention is that a casing is provided on the outside of the machine body, and a door is provided on the outside of the casing.

[0019] By adopting the above technical solution, the chassis can be operated by opening the door.

[0020] A further feature of this invention is that the bottom of both the body and the chassis is fixedly connected to support legs, and the bottom of each support leg is fixedly connected to an anti-slip pad.

[0021] By adopting the above technical solution, the support legs support the body and chassis, improving stability.

[0022] A further feature of this invention is that the number of drainage holes is several, and the several drainage holes are distributed in a rectangular array.

[0023] By adopting the above technical solution and setting multiple drainage holes, wastewater can be discharged through multiple drainage holes.

[0024] A further feature of this invention is that a fan bracket is fixedly installed inside the fan cover, and the fan is located inside the fan bracket.

[0025] By adopting the above technical solution, the fan is installed inside the fan cover through the fan bracket, which improves the stability of the fan during operation.

[0026] The beneficial effects of this utility model are:

[0027] This invention, through the arrangement of a body, purification chamber, T-connector, air pump, spray pipe, atomizing nozzle, exhaust port, hood, fan, mounting block, isolation plate, drain hole, wastewater tank, drain pipe, valve, and activated carbon mesh, allows for the treatment of salt mist within the purification chamber by spraying it through the atomizing nozzle after the salt spray test is completed inside the body. The air pump draws the fumes into the T-connector, which then flows into the purification chamber. The spray pipe is connected to a water source, and a water pump draws water into it. The water is then sprayed into the purification chamber through the atomizing nozzle, thus effectively treating the salt mist inside the purification chamber. The process involves purifying the acidic gases inside the salt spray, and storing the wastewater through the drainage holes inside the isolation plate in the wastewater tank. Then, the staff starts the fan, drawing the salt spray from the purification chamber into the hood. An activated carbon mesh is placed inside the exhaust port; before entering the hood, the smoke is purified by the activated carbon inside the mesh, adsorbing impurities within the salt spray. The smoke is then discharged through the hood, thus enabling the device to purify the salt spray and reduce the emission of harmful gases during the discharge process.

[0028] This invention, through the arrangement of a horizontal shaft, a machine cover, a handle, a motor, a locking block, and a powder cylinder, allows the machine cover to be rotatably connected to the inside of the machine body via the horizontal shaft. The machine cover closes the machine body, while opening it allows the powder coating to be placed inside. The transparent design of the machine cover allows operators to observe the testing process inside the machine body. After filling the powder cylinder with the powder coating, the powder cylinder is locked into the locking block. Starting the motor drives the powder cylinder to rotate, causing the powder coating to move and ensuring sufficient contact between the salt spray and the powder coating, thus improving the testing effect.

Water pipe 14 and drain pipe 14 are equipped with valves 15 inside. Activated carbon mesh 26 is fixedly connected inside exhaust port 7, and activated carbon is placed inside the activated carbon mesh 26. After the salt spray test is completed inside the machine body 1, the air pump 4 is started, drawing the smoke into the three-way pipe 3, which then enters the purification chamber 2. Spray pipe 5 is connected to a water source, and water is drawn into the spray pipe 5 by a water pump. The water is sprayed into the purification chamber 2 through atomizing nozzles 6, thus spraying the salt spray inside the purification chamber 2 to purify the acidic gases inside. Wastewater enters the wastewater tank 13 through the drain hole 12 inside the isolation plate 11 for storage. Then, the operator starts the fan 9, causing the air inside the purification chamber 2 to be sprayed. The salt spray is drawn into the interior of the hood 8. The activated carbon mesh 26 is located inside the exhaust port 7. Before entering the hood 8, the smoke is purified by the activated carbon inside the mesh 26, allowing impurities within the salt spray to be adsorbed. The smoke is then discharged through the hood 8, thus purifying the salt spray and reducing the emission of harmful gases. A horizontal shaft 16 is fixedly connected inside the body 1, with a cover 17 fitted onto its center. The cover 17 is rotatably connected to the body 1 via the horizontal shaft 16, closing the body 1. Opening the cover 17 allows powder coating to be placed inside the body 1.

A powder cylinder 21 is engaged inside the locking block 20. Powder coating is filled into the powder cylinder 21, and then the powder cylinder 21 is engaged with the locking block 20. Starting the motor 19 drives the powder cylinder 21 to rotate. This rotation causes the powder coating to move, ensuring sufficient contact between the salt spray and the powder coating, thus improving the testing effect. Two powder cylinders 21 are used, symmetrically arranged, allowing for simultaneous testing of multiple batches of powder coating.A motor housing 22 is fixedly connected to the outside of the main body 1.

The spray pipe 5 is connected to a water source, and the water pump draws water into the spray pipe 5. The water is then sprayed into the purification chamber 2 through the atomizing nozzle 6, thereby spraying the salt spray inside the purification chamber 2 to purify the acidic gases inside the salt spray. The wastewater enters the wastewater tank 13 through the drain hole 12 inside the isolation plate 11 for storage. Then, the operator starts the fan 9, which draws the salt spray inside the purification chamber 2 into the hood 8. The activated carbon mesh 26 is placed inside the exhaust port 7. Before entering the hood 8, the smoke is purified by the activated carbon inside the activated carbon mesh 26, thus removing impurities from the salt spray. The salt spray is adsorbed inside the activated carbon mesh 26 and then discharged through the hood 8, thus enabling the device to purify the salt spray and reduce the emission of harmful gases during the salt spray discharge process. The cover 17 is rotatably connected to the inside of the body 1 via the horizontal shaft 16. The cover 17 closes the body 1, and the powder coating is placed inside the body 1 when the cover 17 is opened. The transparent cover 17 allows the staff to observe the test situation inside the body 1 in a timely manner. The powder coating is filled into the powder cylinder 21, and then the powder cylinder 21 is snapped into the inside of the locking block 20. The motor 19 is started, which drives the powder cylinder 21 to rotate. The rotation of the powder cylinder 21 causes the powder coating to move, allowing the salt spray to fully contact the powder coating and improve the test effect.
