Description

Technical Field

[0001] This invention relates to a dust suppression device for safe chemical production, and more particularly to a dust suppression device for safe chemical production with dust removal and humidification functions. Background Technology

[0002] Dust is generated during chemical production. If the dust in the factory is not treated in time, it can be inhaled by workers and cause respiratory diseases. Moreover, there is a risk of explosion when the dust is diffused.

[0003] In the process of chemical production, dust needs to be treated. In the existing technology, dust-laden air is generally extracted by a fan and the dust is filtered through a filter. However, this method has the following problems: First, when filtering dust through a filter, dust may adhere to the filter, which will reduce the filtration effect of the filter. Second, the dust generated during chemical production will absorb moisture from the air, and the existing treatment devices can only purify the dust and do not have a humidification function.

[0004] For example, Chinese patent application number 202220282560.0 discloses a dust suppression device for chemical safety. It uses a motor to drive the fan blades to rotate, thereby extracting dusty air and filtering it through a filter screen. The filter screen can be disassembled for cleaning. Although the filter screen can be disassembled for cleaning, it cannot clean the dust adhering to the filter screen at the same time during operation.

[0019] In addition, the present invention also includes a dust removal mechanism, which includes a mounting ring 51, a magnetic ball 52, a reciprocating screw 53, a motor 54, and a lifting seat 55.

The guide plate 513 is made of a permanent magnet.

[0020] In addition, the humidification mechanism 4 of the present invention includes an installation chamber 41, a water tank 42, and a water supply main pipe 43; a first transfer pipe 44 and a second transfer pipe 45 are respectively fixedly connected to the left and right side plates of the installation chamber 41. The first transfer pipe 44 is connected to the head of the air outlet pipe. A negative pressure pipe 46 is fixedly connected between the first transfer pipe 44 and the second transfer pipe 45. The water tank 42 is fixedly connected to the installation chamber 41. The water supply main pipe 43 is located on the installation chamber 41. One end of the water supply main pipe 43 is open and the other end is closed. The open end of the water supply main pipe 43 is connected to the water tank 42, and the water supply main pipe 43 is connected to the negative pressure pipe 46 through a water supply auxiliary pipe 47.

[0021] The negative pressure pipe 46 is arranged in a butterfly shape between the first transfer pipe 44 and the second transfer pipe 45, and the diameter of the negative pressure pipe 46 is 1 / 5 to 1 / 3 of the diameter of the first transfer pipe 44 and the second transfer pipe 45.

[0022] The installation chamber 41 is equipped with a PLC controller 48, the hood 33 is equipped with a humidity sensor 49, the water supply main pipe 43 is equipped with a first solenoid valve 410, the power interface of the PLC controller 48 is electrically connected to an external power source, the signal input terminal of the PLC controller 48 is electrically connected to the humidity sensor 49, and the control output terminal of the PLC controller 48 is electrically connected to the first solenoid valve 410.

[0023] In addition, a water supply pipe 411 is fixedly connected to the upper right side of the water tank 42. A second solenoid valve 412 is installed on the water supply pipe 411. A level gauge 413 is also fixedly connected to the top plate of the water tank 42. The measuring end of the level gauge 413 extends into the water tank 42. The level gauge 413 is electrically connected to the signal input terminal of the PLC controller 48. The second solenoid valve 412 is electrically connected to the control output terminal of the PLC controller 48.

[0024] One specific embodiment of the present invention is as follows: like Figure 1 In the initial state, the position of the collar 13 corresponds to the position of the support rod 11, the fixing screw 16 enters the fixing groove 15, and the position of the collar 13 is fixed by the fixing nut 17. The setting of the rubber sealing sleeve 18 can ensure that the collar 13 has good sealing performance.

[0025] The usage process of this invention is as follows: When the fan 3 is started, it draws air through the air inlet pipe, creating a negative pressure in the treatment cylinder 1. Dust-laden air from the outside enters the treatment cylinder 1 through the air intake 31. Under the action of the steel filter cartridge 2, the dust is trapped, and the clean air enters the steel filter cartridge 2. Then, the clean air enters the air hood 33 through the exhaust 32, and then enters the humidification mechanism 4 through the air inlet pipe and the air outlet pipe in sequence.

[0026] When the motor 54 is working, it drives the reciprocating screw 53 to rotate. Since the lifting seat 55 meshes with the reciprocating screw 53 through the reciprocating threaded sleeve 512, and the lifting seat 55 is limited by the cooperation between the guide plate 513 and the guide rod 510, the lifting seat 55 moves up and down reciprocally when the reciprocating screw 53 rotates.

[0027] Since the guide plate 513 is made of permanent magnet, when the guide plate 513 moves up and down with the lifting seat 55, when the guide plate 513 moves to the position of the corresponding magnetic ball 52, the magnetic attraction between the two will cause the magnetic ball 52 to swing towards the steel filter cartridge 2 and hit the steel filter cartridge 2. When the guide plate 513 moves up and down, the magnetic balls 52 at different heights continuously hit the steel filter cartridge 2, thereby knocking off the dust adhering to the steel filter cartridge 2. The knocked-off dust slides down on the mounting seat 21.

[0028] When there is a lot of dust, the fan 3 and motor 54 can be stopped, and then the fixing nut 17 can be unscrewed. The collar 13 can be lifted through the flange 14 to clean the dust at the support rod 11.

[0029] like Figure 9As shown, the humidity sensor 49 can detect the humidity of the air. When the humidity is low, the first solenoid valve 410 is opened. At this time, clean air is discharged in sequence through the air outlet pipe 35, the first transfer pipe 44, the negative pressure pipe 46, and the second transfer pipe 45. During this process, the water in the water tank 42 enters the negative pressure pipe 46 through the main water supply pipe 43 and the secondary water supply pipe 47, and mixes with the high-speed flowing gas, thereby humidifying the air.

[0030] The water supply pipe 411 is connected to the external tap water pipe. The level gauge 413 can detect the water level in the water tank 42. When the water level is low, the PLC controller 48 controls the second solenoid valve 412 to open, thereby adding water to the water tank 42 through the water supply pipe 411.
