Description

Technical Field

[0001] This utility model belongs to the field of zinc processing technology, and in particular relates to a zinc dust capture device. Background Technology

[0002] Zinc dust capture refers to the technology for effectively controlling and collecting zinc dust generated during zinc plating, zinc alloy manufacturing, and other production processes involving zinc materials. Due to the high toxicity and flammability of zinc dust, if left uncontrolled, it can cause serious pollution to the working environment, threaten worker health, and even potentially cause safety accidents such as fires or explosions. Currently, zinc dust capture technologies mainly include mechanical dust collection, wet dust collection, and electrostatic dust collection. Mechanical dust collection uses the suction force generated by a fan to draw dust into dust collection equipment, such as bag filters or cyclone dust collectors, and then captures the dust through filter materials. Wet dust collection uses water or other liquids to mix with the dust, separating the dust from the gas through spraying, washing, or other methods. Electrostatic dust collection uses a high-voltage electric field to charge the dust, and then uses the electric field force to attract the charged dust to a collection plate. Although existing zinc dust capture technologies can reduce zinc dust pollution to some extent, they still have drawbacks such as low automation, high energy consumption, and unstable dust capture efficiency. Utility Model Content

[0017] (2) The zinc dust capture device described in this utility model provides two control modes, forced start and automatic start, through a two-position switch SA1.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] The zinc dust capture device includes a power supply, a blower M1, a transformer T2, a rectifier T1, and a control module. In this technical solution, the power supply is preferably three-phase electricity, which powers the blower. The power supply is converted to 24V DC after passing through the transformer and rectifier and is connected to the control module. The control module is electrically connected to the dust sensor to control the start and stop of the blower according to the zinc dust concentration.

[0024] Specific examples Figure 1 As shown, the capture device also includes a start / stop switch SB1. The input terminal of the start / stop switch SB1 is electrically connected to the positive terminal of the rectifier T1, the output terminal of the start / stop switch SB1 is electrically connected to the input terminal of the control module, and the output terminal of the control module is electrically connected to the negative terminal of the rectifier T1.

[0025] Furthermore, the capture device also includes a fuse FU1 and a thermal relay FR1, which are connected in series between the power supply and the hair dryer M1 to protect the load circuit when the hair dryer M1 is working.

[0026] Specifically, the control module includes transistor K1, relay KA1 coil and KA1 switch, relay KT1 coil and KT1 switch, and relay KM1 coil and KM1 switch. The source of transistor K1 and the input terminals of relay KT1 switch and relay KA1 coil are connected in parallel to the positive terminal of rectifier T1. The output terminals of relay KT1 coil, relay KM1 coil, and relay KA1 coil are connected in parallel to the negative terminal of rectifier T1. The input terminal of relay KT1 switch is electrically connected to the output terminal of relay KA1 switch, and the input terminal of relay KA1 switch is electrically connected to the emitter of transistor K1. The control module also includes a two-position changeover switch SA1. The input terminal of two-position changeover switch SA1 is electrically connected to the positive terminal of rectifier T1. The normally open contact of two-position changeover switch SA1 is electrically connected to the input terminal of relay KT1 switch, and its normally closed contact is electrically connected to the input terminal of relay KA1 coil. The output terminal of relay KT1 switch is electrically connected to the input terminal of relay KM1 coil. The control module also includes diode K4, whose anode is electrically connected to the input terminal of relay KA1 coil, and whose cathode is electrically connected to the input terminal of relay KM1 coil.

[0027] Control Module Control Principle: The worker selects the control mode via a two-position changeover switch SA1. The control modes are forced start and automatic start. During forced start, the normally closed contact of the two-position changeover switch SA1 closes, energizing the coils of relays KM1 and KA1. When relay KM1 closes, the blower M1 is energized and starts, providing negative pressure to capture zinc dust. Simultaneously, relay KA1 opens to suppress energizing and closing of relay KT1, preventing current fluctuations in relay KM1. During automatic start, the normally open contact of the two-position changeover switch SA1... When the circuit is closed, the diode K4 is reverse-biased, causing the relay KA1 coil to lose power. The relay KA1 switch remains normally closed. The dust sensor can output a switch signal to the base of the transistor K1 based on whether the zinc dust concentration has reached the capture level. When the zinc dust concentration is too high, the transistor K1 conducts, the relay KT1 coil is energized, and the KT1 switch closes, causing the relay coil KM1 to be energized. When the relay KM1 switch closes, the blower M1 is energized and starts to provide negative pressure to capture the zinc dust. If the zinc dust concentration is not high, the transistor K1 is cut off, and the blower M1 stops operating.

[0028] Optionally, the control module also includes a pull-down resistor R1. The dust sensor and the pull-down resistor R1 are connected in parallel to the base of the transistor K1. When the dust sensor does not transmit a high-level signal, the pull-down resistor R1 pulls the base of the transistor K1 to zero to ensure that the transistor is in the cut-off state and to prevent misjudgment of dust concentration.

[0029] Specifically, in this technical solution, relay KA1 is preferably an intermediate relay, relay KT1 is preferably a time relay, and relay KM1 is preferably a control relay. The information transmission, signal processing, control method, and control logic involved can all be implemented using existing technologies.
