Description

TECHNICAL FIELD

[0001] The utility model belongs to dust treatment technical field, and specifically is a dust collector for firecracker charging and packaging integrated machine. BACKGROUND

[0002] In the manufacturing process of fireworks and firecrackers, the charging process is particularly critical. The charging process usually includes steps such as powder mixing, metering, and filling, which directly determine the quality and performance of the finished product. However, a large amount of dust is inevitably generated during the charging process, which is mainly composed of fine particles of gunpowder and has high risk of explosion and health hazards. Gunpowder dust can easily explode when it reaches a certain concentration in the air and encounters an open flame, electric spark, or high temperature, resulting in personnel casualties and equipment damage.

[0003] The traditional dust control method in the charging process mainly includes workshop ventilation and installation of local dust removal equipment, but the local dust removal equipment can only have good dust removal effect in a certain direction of the charging machine, and there is still a situation of dust dispersion. Patent No. CN220794033U discloses a fireworks inner tube cake charging dust removal device and charging dust collection system, which moves back and forth between the dust falling area and the dust suction port to collect the dust falling in the dust falling area and send it to the dust suction port. This dust collection system can improve the dust removal rate to a certain extent, but it is difficult to remove light small particles and dust in a suspended state. UTILITY MODEL CONTENTS

[0004] The utility model aims to provide a dust collector for firecracker charging and packaging integrated machine to solve the problems in the prior art.

[0005] A dust collector for firecracker charging and packaging integrated machine is provided, which includes:

[0006] A charging machine;

[0007] A packaging cover, the charging machine is arranged inside the packaging cover;

[0008] A plurality of dust removal devices, the dust removal devices are used to filter the dust inside the packaging cover.

[0009] Further, the packaging cover includes a plurality of dustproof vertical curtains arranged on the side wall. The dustproof vertical curtain forms a local seal through its flexible structure, which can effectively reduce the escape of dust from the opening of the cover and avoid completely isolating the inside and outside of the packaging cover. The vertical curtain structure facilitates worker operation and equipment maintenance.

[0010] Further, the dustproof curtain is a PVC anti-static transparent grid curtain. Using the PVC anti-static transparent grid curtain as the dustproof curtain material can prevent static electricity accumulation from igniting gunpowder dust, and the transparent design improves the operation field of vision and work convenience.

[0011] Further, the dust removal equipment comprises a filter cartridge, an air suction duct and an air extraction mechanism, the filter cartridge is fixedly connected with the packaging cover, the air suction duct is in communication with the filter cartridge and located in the inside of the packaging cover, and the air extraction mechanism is in communication with the filter cartridge. The air suction duct sucks dust into the filter cartridge, the filter cartridge retains dust particles through physical filtration, and the air extraction mechanism provides continuous negative pressure to ensure that dust is continuously sucked and removed. Through the cooperation of the filter cartridge, the air suction duct and the air extraction mechanism, dust can be effectively collected and filtered, the dust removal efficiency is improved, and the service life of the equipment is prolonged.

[0012] Further, the air extraction mechanism is arranged outside the packaging cover, and an extension pipe is arranged between the air extraction mechanism and the filter cartridge. By extending the distance between the air extraction mechanism and the inside of the packaging cover through the extension pipe, the electric spark generated by the air extraction mechanism can effectively prevent the dust inside the packaging cover from being ignited.

[0013] Further, a slide is arranged in the packaging cover and opposite to the air suction duct. The dust filtered by the filter cartridge falls back to the inlet of the air suction duct and falls onto the slide, and the slide is designed to be inclined to make the dust slide to the dust collection equipment or be discharged under the action of gravity, so that the dust is prevented from falling to the ground to cause secondary diffusion.

[0014] Further, a spraying assembly is arranged at the high end of the slide. The spraying assembly sprays liquid to wet and clean the surface of the slide, can effectively inhibit the secondary dust raising of the dust on the surface of the slide, and clean the surface of the slide, and the inclined surface of the slide is used to drain the liquid to discharge the dust along a specific path.

[0015] Further, the side wall of the packaging cover is outwardly protruded to form a compartment, and the low end extension section of the slide is located in the compartment. The low end of the slide extends to the compartment, so that the dust is concentrated and collected in an independent area, and the secondary diffusion of the dust in the packaging cover is avoided. The compartment separates the dust collection area from the main operation space, and further reduces the interference of the dust on the charging process.

[0016] Further, the bottom wall of the packaging cover has a sloping structure downwardly inclined to the compartment. The sloping structure makes the dust and liquid flow along the slope under the action of gravity, realizes rapid discharge of the dust and liquid, guides the dust and liquid residues to flow to the compartment and be discharged from the bottom of the packaging cover, and facilitates subsequent cleaning and processing.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] The packaging cover forms a closed environment to isolate the charging process from the outside, and the dust removal equipment filters the dust in the internal air to ensure that the dust concentration is reduced to a safe range. The charging machine is placed in the packaging cover and equipped with dust removal equipment, which can realize the synchronous operation of charging and dust control, effectively reduce the spread of dust in the workshop, and improve the production safety and environmental protection performance.

[0025] However, there are cases where unnecessary detailed description is omitted. For example, there are cases where detailed description of matters well known, repeated description of actually identical structures is omitted. This is to avoid the following description unnecessarily becoming lengthy, facilitating understanding by those skilled in the art. In addition, the drawings and the following description are provided to enable those skilled in the art to fully understand the present application, and are not intended to limit the subject matter recited in the claims.

[0026] Referring to Figs. 1-2 As shown in the drawings, the utility model embodiment, including charging machine 1, package cover body 2 and a plurality of dust removal equipment 3. Charging machine 1 is arranged in the inside of package cover body 2. Dust removal equipment 3 is used for filtering the dust inside package cover body 2.

[0027] Charging machine 1 is encapsulated in package cover body 2, forms a relatively closed operation space. Through the overall airtight structure, dust is controlled in package cover body 2, reduces the risk of external environmental pollution. By limiting the spread of dust, improve production safety, reduce the fire hazard and dust pollution of workshop.

[0028] Package cover body 2 includes a plurality of dustproof vertical curtain 21 being arranged on the side wall, dustproof vertical curtain 21 passes through flexible sealing and local airflow circulation, blocks dust to escape, allows air circulation simultaneously, facilitates dust removal equipment 3 to guide dust to enter the filter system. The design effectively reduces dust leakage, improves the dust removal efficiency of package cover body 2, and retains the convenience of worker operation and equipment maintenance.

[0029] Dustproof vertical curtain 21 uses PVC anti-static transparent grid curtain, the material has anti-static performance, prevents electrostatic spark from igniting dust, and its transparent property optimizes the operation field of view, reduces the risk of explosive powder dust, improves work safety and operation convenience.

[0030] Dust removal equipment 3 includes filter core cylinder 31, suction air duct 32 and air extraction mechanism 33. Filter core cylinder 31 is arranged at the top wall of package cover body 2, suction air duct 32 is communicated with filter core cylinder 31 and is located in the inside of package cover body 2, air extraction mechanism 33 is communicated with filter core cylinder 31 for generating negative pressure air suction area. Dust removal equipment 3 can be provided with multiple on package cover body 2, and multiple suction air ducts 32 carry out dust removal operation in different areas in package cover body 2. Filter core cylinder 31 is provided with filter core for capturing dust particles, suction air duct 32 guides dust to filter core cylinder 31, and air extraction mechanism 33 provides negative pressure to maintain continuous collection of dust. Clean air is directly discharged after filtration, and dust forms an aggregated state after a period of filtration, facilitating collection and processing.

[0031] The air extraction mechanism 33 is arranged outside the packaging cover 2, and an extension pipe 34 is arranged between the air extraction mechanism 33 and the filter cartridge 31. By arranging the air extraction mechanism 33 outside the packaging cover 2 through the extension pipe 34, the distance from the dust area is increased, the electric spark generated by the air extraction mechanism 33 is isolated, the ignition of dust inside the packaging cover 2 is effectively prevented, and the safety of the system is improved.

[0032] A chute 4 is arranged in the packaging cover 2 opposite the air suction duct 32. After a period of dust collection, the dust forms an aggregated state and falls from the air suction duct 32 and falls on the chute 4. The inclined design of the chute 4 causes the dust and material residues to slide under the action of gravity to the dust collection equipment, reducing the secondary diffusion of the dust after falling to the ground.

[0033] Further, the high end of the chute 4 is provided with a spraying assembly 5, which sprays liquid on the surface of the chute 4 and forms a liquid flow under the guidance of the inclined structure of the chute 4. The liquid flow collects the dust on the surface of the chute 4 and then removes the dust. This design avoids some dust that cannot be naturally discharged by its own gravity, so the dust is carried away by the driving of the liquid flow. Compared with the scheme of conveying dust by a conveyor belt, the liquid flow does not need to be driven by electricity, so it will not produce the risk of electric spark, and the safety is higher. The spraying assembly 5 suppresses the secondary dust raising, reduces the influence of dust accumulation on the operation of the equipment, and realizes the self-cleaning function of the chute 4.

[0034] The compartment 22 is an area where the side wall of the packaging cover 2 protrudes outward, which is designed as an independent dust and liquid collection space. The low end of the chute 4 extends into the compartment 22, and the dust and liquid are guided to the compartment 22 by the inclined structure of the chute 4. The compartment 22 is isolated from the main operating space of the packaging cover 2, and the dust settles or is further concentrated in the compartment 22 for processing, avoiding the backflow or secondary diffusion of the dust to the charging space. The compartment 22 can discharge the dust and liquid through subsequent manual cleaning or automatic discharge system, ensuring the long-term operation efficiency and cleanliness of the device.

[0035] The bottom wall of the packaging cover 2 is designed as a slope structure inclined to the compartment 22, and the slope angle can be 2°-5°. The slope structure uses gravity to guide the dust and liquid to the compartment 22 along the slope. The slope structure avoids the random accumulation of dust and liquid in the packaging cover 2, reduces the pollution and cleaning burden of the operating area. After the dust and liquid move to the compartment 22 along the slope, they are deposited or enter the discharge channel, maintaining the cleanliness of the operating area in the device.

[0036] If the dust curtain 21 structure is used for the packaging cover 2, there is a gap between the bottom of the dust curtain 21 and the ground, and the slope structure of the compartment 22 can automatically discharge the liquid and dust from the bottom of the dust curtain 21.

[0037] Note that the present application is not limited to the above-described embodiments. The above-described embodiments are merely examples, and embodiments having substantially the same configuration, function, and effect as the technical idea of the present application are included in the technical scope of the present application. Furthermore, other modes constructed by applying various modifications to the embodiments, or by combining part of the configurations of the embodiments, which can be conceived by those skilled in the art, without departing from the spirit of the present application, are also included in the scope of the present application.
