Description

Technical Field

[0001] The utility model relates to the field of electrostatic spraying equipment, in particular to a heat exchange chamber for electrostatic spraying. Background Art

[0002] Electrostatic spraying refers to a coating method that uses the principle of corona discharge to make the atomized paint negatively charged under the action of a high-voltage DC electric field, and adsorbs on the surface of a positively charged substrate to discharge. Electrostatic spraying equipment consists of a spray gun, a spray cup, and an electrostatic spray high-voltage power supply. The wind speed in the electrostatic spray room is also very important. The exhaust in the spray room is mainly used to remove the solvent vapor generated during the spraying process, so that the content of indoor solvent vapor is below the lower explosion limit concentration of organic solvents to ensure construction safety. Excessive wind speed in the electrostatic spray room will affect the spraying effect. A wind speed adjustment mechanism should be set in the exhaust device.

[0003] After searching the prior art, it was found that during the high-temperature curing stage after electrostatic spraying, the workpiece needs to be kept at a certain temperature, and a heat exchanger is needed to maintain a constant temperature. In the existing device, excess heat is taken away by accelerating air circulation. The electrostatic spraying powder will be separated from the surface of the workpiece due to wind pressure, resulting in a decrease in the spraying effect. The practicality needs to be enhanced.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1 — Figure 5 As shown, a heat exchange chamber for electrostatic spraying includes a main body 1, a supporting mechanism 2 is installed in the main body 1, a heat exchange mechanism 3 is installed on the outside of the main body 1, a fixing mechanism 4 is arranged in the main body 1, the main body 1 includes a heat exchange chamber 101, a sealing door 102 is installed on the front side of the heat exchange chamber 101, a heater 103 is fixedly installed in the heat exchange chamber 101, a control panel 104 is bolted to one side of the heat exchange chamber 101, a mounting plate 105 is bolted to the rear side of the heat exchange chamber 101, and the sealing door 102 forms a closed space inside the heat exchange chamber 101, which has a better high-temperature curing effect on the workpiece of electrostatic spraying.

[0025] In this embodiment, the supporting mechanism 2 includes a turntable 201, which is rotatably connected to the top of the heat exchange chamber 101. The turntable 201 is located in the high-temperature curing chamber 404. A plurality of connecting wires 202 are bolted to the bottom of the turntable 201. A supporting plate 203 is welded to the bottom of the connecting wires 202. When the workpiece is subjected to high-temperature curing, the turntable 201 rotates continuously, and the connecting wires 202 drive the supporting plate 203 to rotate, so that the surface of the workpiece is heated evenly.

[0026] In this embodiment, the heat exchange mechanism 3 includes an air cooler 301, which is connected to the top of the mounting plate 105 by bolts. The air cooler 301 includes a blowing end 3011 and an air intake end 3012. The blowing end 3011 of the air cooler 301 is connected with an exhaust pipe 302, and the other end of the exhaust pipe 302 is connected with an exhaust assembly 303. A negative pressure device 304 is arranged at a relative position to the exhaust assembly 303. The exhaust assembly 303 and the negative pressure device 304 are connected to both sides of the heat exchange chamber 101 by bolts. One side of the negative pressure device 304 is connected with an air intake pipe 305 by bolts, and one end of the air intake pipe 305 is connected to the air intake end 3012. The heat exchange mechanism 3 can exchange heat in the heat exchange chamber 101 with the air cooler 301, so that the inside of the heat exchange chamber 101 maintains a constant temperature, and the high-temperature curing effect is better.

[0027] In this embodiment, the fixing mechanism 4 includes a fixing plate 401, the cross-section of the fixing plate 401 is streamlined, and a plurality of heat dissipation holes 402 are opened in the fixing plate 401. The direction of the heat dissipation holes 402 is perpendicular to the direction of the exhaust component 303 and the negative pressure device 304. The exhaust component 303 and the negative pressure device 304 are located on both sides of the heat exchange chamber 403. One side of the fixing plate 401 is the heat exchange chamber 403, and the other side is the high-temperature curing chamber 404. The heater 103 is located in the high-temperature curing chamber 404. When the exhaust component 303 and the negative pressure device 304 are working, the heat in the high-temperature curing chamber 404 is dissipated into the heat exchange chamber 403 through the heat dissipation holes 402. The air in the heat exchange chamber 403 in the heat exchange chamber 101 is accelerated to flow, and heat is exchanged in the heat exchange chamber 101. The setting of the fixing plate 401 prevents the workpiece from being directly subjected to the pressure of the airflow, which causes the electrostatic spraying powder on the surface to detach, thereby improving the spraying effect.

[0028] Working principle: When the device is in use, the sealing door 102 is opened, the workpiece is fixed on the carrier plate 203, and the sealing door 102 is closed. The sealing door 102 forms a closed space inside the heat exchange chamber 101, which has a better high-temperature curing effect on the workpiece of electrostatic spraying. The control panel 104 is operated to turn on the heater 103 and the turntable 201. The turntable 201 rotates continuously, and the connecting line 202 drives the carrier plate 203 to rotate, so that the surface of the workpiece is heated evenly, and the electrostatic spraying powder is cured at high temperature on the surface of the workpiece. During the curing, a constant The temperature is set to ensure the spraying quality. The control panel 104 is operated to turn on the air conditioner 301, the exhaust component 303 and the negative pressure device 304. The excess heat in the high-temperature curing chamber 404 is dissipated through the heat dissipation holes 402. The heat is temporarily accumulated in the heat exchange chamber 403. The exhaust component 303 and the negative pressure device 304 accelerate the air flow in the heat exchange chamber 403. Due to the streamlined setting of the fixing plate 401 and the perpendicular orientation of the heat dissipation holes 402 and the exhaust component 303, the electrostatic spraying powder is prevented from being carried away during the air flow, thereby ensuring a good spraying effect.
