Description

Technical Field

[0001] This invention belongs to the field of aluminum electrolysis technology, and in particular relates to a dry fog dust suppression system for aluminum electrolysis workshops. Background Technology

[0002] A dry fog dust suppression system in an aluminum electrolysis workshop is a device used to control particulate matter and dust in the air inside the workshop. Because the aluminum electrolysis production process generates a large amount of particulate matter and dust, these particles and dust can negatively impact worker health and the normal operation of workshop equipment, thus requiring appropriate control measures. By using a dry fog dust suppression system in an aluminum electrolysis workshop, particulate matter and dust in the air can be effectively controlled, improving workers' working conditions and the operating efficiency of workshop equipment. Simultaneously, it also helps protect the environment and reduce pollutant emissions.

[0003] Dry fog dust suppression involves combining water mist with dust particles in the air to form agglomerates of dust and water mist. These agglomerates settle down due to gravity, thus suppressing dust and controlling dust dispersion at its source. Dry fog dust suppression technology can effectively solve the problem of dealing with fugitive dust emissions in partially enclosed or semi-enclosed environments.

[0004] Existing dry fog dust suppression systems in aluminum electrolysis workshops typically require nozzles to be mounted on brackets. While the nozzles can adjust the spray angle and range, they cannot effectively suppress dust from all angles within the aluminum electrolysis workshop. Furthermore, they cannot be adjusted based on the particulate matter concentration in different parts of the space, resulting in less than ideal dust suppression performance. Additionally, the nozzles are usually cleaned manually on a regular basis, which is inefficient, costly, and ineffective. Summary of the Invention

[0005] The purpose of this invention is to provide a dry fog dust suppression system for aluminum electrolysis workshops. By setting multiple nozzles, the dry fog dust suppression system achieves a high dust removal rate and can remove dust from all directions. The position of the nozzles can be freely adjusted. By setting a self-cleaning component and a translation mechanism, the dry fog dust suppression system has self-cleaning capability, solving the problems of existing dry fog dust suppression systems that are difficult to remove dust from all directions and are not convenient for regular cleaning.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a dry fog dust suppression system for an aluminum electrolysis workshop, comprising a spray assembly, a conveyor box, a dust detection mechanism, a self-cleaning assembly, and a translation mechanism. Multiple spray assemblies are installed and fixed at equal intervals below the conveyor box. Each spray assembly includes a first semi-circular frame and multiple sliding sleeves evenly distributed along the circumference, slidably fitted onto the arc-shaped portion of the first semi-circular frame. The sliding sleeves are locked by set screws. A nozzle is fixedly mounted through a support plate on the side of the sliding sleeve. The nozzle is fixedly connected to one end of a conveying rigid pipe, and the other end of the conveying rigid pipe is fixedly connected to a solenoid valve. The solenoid valve is fixedly connected to a multi-way connector via a flexible hose. The multi-way connector is fixedly connected to a connecting pipe at the bottom of the conveyor box, and the multi-way connector is fixed to the bottom of the conveyor box by a first C-shaped fastener.

[0007] Each sliding sleeve is fixed with a telescopic dust detection mechanism at its bottom, which is used to detect the dust concentration at different locations in the space; each spray assembly is equipped with a self-cleaning component on its side, which is used to clean the nozzle. The translation mechanism is fixed to the top of the conveyor box and drives multiple self-cleaning components to move to the bottom of the corresponding spray assembly through mechanical transmission.

[0008] Furthermore, the end of the first semicircular frame is fixedly connected to the side of the conveyor box.

[0009] Furthermore, the smoke and dust detection mechanism includes a multi-section telescopic rod, a first connecting rod, a second connecting rod, a mounting cylinder, a smoke and dust sensor, and audible and visual warning lights.

The bottom of the mounting cylinder is fixed with a smoke and dust sensor, and multiple audible and visual warning lights are evenly distributed around the circumference on the cylindrical surface of the mounting cylinder.

[0010] Furthermore, the self-cleaning component includes a second semicircular frame and an arc-shaped plate slidably disposed on the arc-shaped part of the second semicircular frame; a plurality of cleaning brushes and spray holes are evenly distributed along the circumference on one side of the inner surface of the arc-shaped plate, the cleaning brushes and spray holes are staggered, and a water pipe connector is provided on the side of the arc-shaped plate.

[0011] Furthermore, the second semicircular frame is larger than the first semicircular frame, and the cleaning brush comes into contact with the nozzle.

[0012] Furthermore, the self-cleaning component also includes a semi-gear ring, a gear, a first motor, and a motor frame; the semi-gear ring is fixed on the other side of the inner surface of the arc plate, the semi-gear ring meshes with the gear, the gear is fixedly sleeved on the output shaft of the first motor, the first motor is fixed inside the motor frame, and the motor frame is fixedly connected to the second semi-circular frame.

[0013] Furthermore, the translation mechanism includes a nut seat, a guide rail, a lead screw, a bearing seat, and a second motor; multiple nut seats are provided, each corresponding to a self-cleaning component; the top of the nut seat is fixedly connected to the crossbar of the second semi-circular frame, the bottom of the nut seat is slidably connected to the guide rail, the nut seat is movably sleeved on the lead screw, one end of the lead screw is rotatably connected to the bearing seat, and the other end of the lead screw is fixedly connected to the output shaft of the second motor; the guide rail, the bearing seat, and the second motor are all fixed to the top of the conveyor box.

[0015] The present invention has the following beneficial effects: This invention achieves a high dust removal rate and all-around dust removal by setting multiple nozzles in the dry fog dust suppression system. The first semi-circular frame and sliding sleeve allow the nozzle position to be freely adjusted to meet the actual usage requirements on site.

[0016] This invention, by incorporating a smoke and dust detection mechanism, enables the dry fog dust suppression system to detect particulate matter concentration with high accuracy. It can detect various locations within a space, and the smoke and dust sensor's position is easily adjustable for convenient detection of desired areas. Furthermore, the inclusion of separate and overall audible and visual warning lights ensures that when the particulate matter concentration in the space is too high, both lights will issue an alert, prompting staff to take timely action. The system also displays the specific location within the space where the particulate matter concentration is excessive, providing better visual feedback.

[0017] This invention enables the dry fog dust suppression system to have self-cleaning capabilities by setting up a self-cleaning component and a translation mechanism. The nozzles are brushed with a cleaning brush and rinsed through the spray holes to prevent the nozzles from being clogged by dust, dirt and other impurities, which would affect the spraying effect. Regular cleaning of the nozzles can maintain their normal working condition and ensure that the spraying effect reaches the best level. Attached Figure Description

Multiple audible and visual warning lights 36 are evenly distributed along the circumference on the cylindrical surface of the mounting cylinder 34.

[0025] The dust detection mechanism 3 enables the dry fog dust suppression system to detect particulate matter concentration with high accuracy, allowing for detection at various locations within the space. The dust sensor 35 is easily adjustable to facilitate detection of desired areas. The audible and visual warning lights 36 issue an alert when particulate matter concentration is too high, prompting staff to take timely action. The warning lights 36 also display the specific location of the high concentration, providing better visual feedback.

The multiple nut seats 51 drive their respective self-cleaning components 4 to move until the self-cleaning components 4 move to the bottom of the spray assembly 1. Then, the self-cleaning components 4 clean the nozzle 15 to prevent the nozzle 15 from being blocked by dust, dirt and other impurities, which would affect the spraying effect. Regularly cleaning the nozzle 15 can maintain the normal working condition of the nozzle 15 and ensure that the spraying effect reaches the best effect.

[0030] Among them, such as Figure 7 As shown, a control box 22 is provided at one bottom end of the conveyor box 2, and a main audible and visual warning light 23 is provided at the bottom of the control box 22; the conveyor box 2 is fixed to the roof of the workshop by the second C-shaped fastener 24.

The dust sensor 35 monitors the particulate matter concentration in the workshop. The controller in the control box 22 controls the opening and closing of the solenoid valve 17 based on the particulate matter concentration at each spatial location, and adjusts the spray volume at each spatial location. When the concentration of particulate matter in the space is too high, the separate audible and visual warning light 36 and the main audible and visual warning light 23 will issue a warning to remind staff to deal with it in time.
