Description

Technical Field

[0001] The present invention relates to a wet dust collector, and more particularly to a self-excited wet dust collector with flow and pressure monitoring. Background Art

[0002] When polishing and grinding the outer surface of a workpiece, dust will be generated. The dust floating in the air will pollute the environment and seriously endanger the health of the staff. Moreover, some dust can even cause explosions. Therefore, it is essential to use a dust collector to handle the dust. Dust collectors are divided into dry dust collectors and wet dust collectors, among which wet dust collectors are more widely used. Wet dust removal is a method of purifying gas by making water fully contact with the dust-containing gas and washing down the dust particles. It is particularly suitable for treating dust-containing gases that are high-temperature, high-humidity, flammable, and explosive. Traditional wet dust collectors use a water pump for water spraying (that is, using a water pump to pump water into the wet dust collector through a pipeline for dust spraying), but the washing liquid will become dirtier and dirtier as the dust removal time increases, which will cause the water pump to be blocked and shorten its service life. For this reason, self-excited wet dust collectors have emerged on the market. They use the attraction of a fan to make water self-excite at the air passage gap, eliminating the need for water spraying by a water pump to generate water mist, thus preventing the water pump blockage phenomenon.

[0003] To ensure the dust removal effect and use safety, a monitoring and alarm device for the water flow and water pressure of the wet dust collector should be set. The existing self-excited wet dust collectors are not convenient for installing a water flow monitoring device and a water pressure monitoring device, and cannot meet the requirements of safe production. Summary of the Invention

[0004] In view of the above deficiencies, the present invention provides a self-excited wet dust collector with flow and pressure monitoring, which has the advantages of simple structure and simultaneously having water flow monitoring and water pressure monitoring.

[0005] To achieve the above object, the present invention adopts a self-excited wet dust collector with flow and pressure monitoring, which includes a water collecting box, a water outlet trough, a flow monitoring device, and a pressure monitoring device. A water outlet is formed at the bottom of the water collecting box, and a water pipe is connected to the water outlet. The other end of the water pipe is connected to the water outlet trough. The flow monitoring device is arranged on the water pipe, and the pressure monitoring device is connected to the water outlet trough.

[0006] The present invention is further configured such that a section of the water outlet trough on one side is lower than the other sides, and the installation height of the pressure monitoring device is lower than the height of the water outlet.

[0007] The present invention is further configured such that the self-excited wet dust collector further includes a dust removal base, which is arranged below one side of the water outlet trough. A flowing water plate is connected between the water outlet trough and the dust removal base, and the upper end of the flowing water plate is connected to the water outlet of the water outlet trough.

[0008] The present invention is further configured such that the self-excited wet dust collector further includes a housing. A water storage tank is formed below the housing, a negative pressure chamber is formed inside the housing above the water storage tank, a water collection box is disposed in the negative pressure chamber, and a water outlet groove and a dust removal seat are disposed outside the negative pressure chamber.

[0009] The present invention is further configured such that the housing forms a cleaning opening above the water outlet groove, and a movable cleaning door is provided on the cleaning opening.

[0010] The present invention is further configured such that a dirt cleaning opening is provided on the water pipe, and a dirt cleaning cover is provided on the dirt cleaning opening.

[0011] The present invention is further configured such that the water pipe includes a longitudinal pipe and a transverse pipe. The longitudinal pipe is connected to the water outlet, and the transverse pipe is connected to the water outlet groove.

[0012] The present invention is further configured such that the water pipe includes a three-way joint. The longitudinal pipe and the transverse pipe are connected into an L shape through two interfaces of the three-way joint. One end interface of the three-way joint that is not connected to the water pipe is the dirt cleaning opening, and a dirt cleaning cover is provided on the dirt cleaning opening.

[0013] The present invention is further configured such that a water mist separation device is provided above the water collection box in the negative pressure chamber. A water collection inclined plate is formed below the water mist separation device. The lower side of the water collection inclined plate is connected above the water collection box, and the water separated by the water mist separation device is concentrated into the water collection box through the water collection inclined plate.

[0014] The present invention is further configured such that a shock wave channel is formed at the bottom of the negative pressure chamber. The shock wave channel is arc-shaped. The lower opening of the shock wave channel faces the dust removal seat, and the upper opening of the shock wave channel is provided above the water collection box.

[0015] The present invention is further configured such that the pressure monitoring device is connected to the side wall of the water outlet groove close to the bottom of the water, and the pressure monitoring device is a pressure sensor.

[0016] The beneficial effects of the present invention are as follows: The water collection box is connected to a flow monitoring device. The water collected by the water collection box must flow back to the dust removal station through the flow monitoring device. All the water at the dust removal station comes from the water collection box and needs to pass through the flow monitoring device. Therefore, the flow monitoring device can accurately monitor the water flow during dust removal, ensuring the dust removal effect and usage safety. A pressure monitoring device is arranged at the bottom of the water outlet tank to monitor the water pressure of the water outlet tank, which can accurately monitor whether there is water flowing out of the water outlet tank. The specific process is that when the water pressure of the pressure monitoring device is slightly higher than the water pressure at the lowest water outlet height of the water outlet tank, it indicates that there is water flowing out of the water outlet tank into the water flow plate, proving that the dust removal work is operating correctly. A tee joint is used to connect the water collection box and the water outlet tank, and a dust removal cover is set at one of the interfaces, through which the dust accumulated in the water pipe can be removed by opening the dust removal cover. The water collection box is arranged below the water mist separation device, which can fully collect the water separated by the water mist separation device, and ensure that the water can be concentrated in the water collection box through the water collection inclined plate; the water in the water collection box flows into the dust removal seat through the water flow plate and combines with the dust, and more water mist is generated through the water mist generating structure with a round tip, ensuring more sufficient combination of water and dust; the shock wave channel at the lower end of the negative pressure cavity can generate shock waves through negative pressure, and the inlet of the shock wave channel faces the dust removal seat, which can accurately absorb dust and has a better dust removal effect.
