Description

Dust collection system

The present invention relates to a dust collection system for absorbing dust.

A dust collector is a device that collects suspended dust and mist from a gas. After the previous dust collector is manually turned on, as long as the fan is not broken, it has been collecting dust. In actual work, if there is an abnormality in the workshop or machine, the workshop will have a fire. At this time, the dust collection will make the fire more serious. Therefore, the operation of the previous dust collector lacks effective monitoring and control.

In view of the above, it is necessary to provide a dust collecting system capable of real-time monitoring and control.

A dust collecting system includes a dust collecting mechanism including a fan. The dust collection system further includes a control module. The control module includes an electric control box and at least one sensing device, and the fan and the sensing device are electrically connected to the electric control box. The sensing device is configured to collect the operating parameter data and transmit the data to the electric control box. The electric control box is configured to receive and discriminate the data sent by the sensing device, and issue a control command to the fan to control the operation and shutdown of the fan. . The dust collecting mechanism further comprises a collecting duct, the control module further comprising a damper mounted on the air collecting duct, the damper being electrically connected to the electric control box for opening or closing under the control of the electric control box When the data sent by the sensing device is abnormal, the electric control box controls the fan to stop and controls the damper to be closed. The dust collecting mechanism further includes a cyclone dust collecting cylinder, a first air guiding pipe, a spraying device, a second air guiding pipe and an exhaust pipe, and the first air guiding pipe is connected between the cyclone dust collecting cylinder and the spraying device, The second air guiding duct is connected between the spraying device and the fan, and one end of the exhaust pipe is connected to the fan.

The dust collecting system instantaneously monitors the operating parameters of the dust collecting system by the sensing device, and transmits the monitoring parameters to the electric control box. When an abnormality occurs in the plant or the dust collecting system, the electric control box can control the fan to stop, and the dust collecting system stops working. The above dust collecting system can realize the real-time monitoring and control of the dust collecting operation, thereby preventing fire and explosion, and making the production more safe.

1 is a schematic view of a dust collecting system according to an embodiment of the present invention.

2 is a block diagram of a dust collecting system according to an embodiment of the present invention.

A dust collecting system provided by the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

Referring to FIG. 1 and FIG. 2 simultaneously, the dust collecting system 100 of the embodiment of the present invention is installed outside the factory building for collecting suspended dust and mist from the gas discharged from the factory to purify the gas. The dust collection system 100 includes a dust collection mechanism 10 and a control module 20.

The dust collecting mechanism 10 includes a collecting duct 11, a cyclone dust collecting cylinder 12, a first air guiding duct 13, a shower device 14, a second air guiding duct 15, a fan 16, and an exhaust duct 17. One end of the air duct 11 is connected to a dust source, such as a factory interior, and the other end is connected to the cyclone dust collecting cylinder 12. The first air guiding duct 13 is connected between the cyclone dust collecting cylinder 12 and the shower device 14, and the second air guiding duct 15 is connected between the spraying device 14 and the dust collecting fan 16, and one end of the exhaust duct 17 and the dust collecting device The fan 16 is connected, and the other end discharges the purified gas out of the dust collecting system 100.

The cyclone dust collecting cylinder 12 is used for centrifuging the gas sucked by the collecting duct 11, so that the heavier impurities in the gas are first lowered to the bottom of the cyclone dust collecting drum 12, and the lighter impurities can pass through the first air guiding duct 13 The shower device 14 is reached.

The shower device 14 includes a housing 141, a water tank 142, a water pump 143, and a shower assembly and a filter screen (not shown) mounted in the housing 141. When the gas is introduced into the casing 141, the filter gas is filtered. The water in the water tank 142 is transferred to the spray assembly by the water pump 143, and then the water is sprayed to the filter to cause the impurities on the filter to fall on the bottom of the spray device 14.

The control module 20 is used to instantly monitor the operating parameters of the dust collecting system 100 and control the dust collecting operation. The control module 20 includes an electrical control box 21, a damper 22, and at least one sensing device. In the present embodiment, the sensing device includes a thermal sensor 23, an electromagnetic flow meter 24, a water level monitor 25, and an air speed monitor 26.

The electric control box 21 is electrically connected to the fan 16, the damper 22 and the sensing devices, and is used for collecting data of various parameter monitoring and judging the data. When the parameter is abnormal, the electric control box 21 sends a control command to the fan 16, and controls the dust collecting system 100 to stop the dust collecting operation.

The damper 22 is mounted on the air duct 11, and when the fan 16 is stopped, the electric control box 21 controls the damper 22 to be closed to prevent the gas from flowing back to the factory.

A thermal detector 23 is mounted on the air duct 11 for monitoring the temperature of the revenue gas. When a temperature abnormality is detected, for example, there is a fire in the factory, the electric control box 21 will control the dust collection system 100 to stop working.

The electromagnetic flow meter 24 is mounted on the water pump 143 of the shower device 14 for monitoring the flow rate of the spray water.

The water level monitor 25 is mounted on the water tank 142 of the shower device 14 for monitoring whether the water level in the water tank 142 is up to standard.

The wind speed monitor 26 is mounted on the second air duct 15 for monitoring whether the wind speed of the gas is up to standard.

In addition, the control module 20 may further include other sensing devices, such as an acousto-optic alarm 27, to issue an abnormal reminder by the sound and light alarm when the working parameters are abnormal. Taking the installation of the wind speed monitor 26 as an example, first, an opening is formed in the second air guiding duct 15, one end of the wind speed monitor 26 is installed in the second air guiding duct 15, and the other end of the wind speed monitor 26 is borrowed. The pad is fixed outside the second air duct 15 and electrically connected to the electric control box 21 by a wire (not shown).

When the above sensing device is installed, the sensing device can be installed by punching and replenishing the workpiece on the basis of the previous pipe without changing the main structure of the dust collecting system 100.

The dust collecting system 100 provided by the present invention is equipped with a control module 20, which includes an electric control box 21, a damper 22 and a plurality of sensing devices, and the gas of the dust collecting system is instantly monitored by a plurality of sensing devices. Operating parameters such as temperature, gas wind speed, spray water flow rate and tank water level, and various monitoring parameters are transmitted to the electric control box 21. When an abnormality occurs in the plant or the dust collecting system, the electric control box 21 can control the fan 16 to stop, and the dust collecting system 100 stops the operation. The dust collecting system 100 can realize the real-time monitoring and control of the dust collecting operation, thereby preventing fire and explosion, and making the production more safe.
