Description

Technical Field

[0001] This utility model relates to the field of energetic material processing technology, and in particular to a dust recovery structure for energetic material processing. Background Technology

[0002] Energetic materials, such as explosives and propellants, generate a large amount of dust during processing. This dust not only contains potentially dangerous energetic components, but also poses a serious threat to the environment and the health of operators. On the one hand, energetic material dust is flammable and explosive. When it reaches a certain concentration in the air, it can easily explode when exposed to ignition sources, static electricity, or other triggering factors, causing major safety accidents. On the other hand, long-term inhalation of energetic material dust can cause irreversible damage to the respiratory and nervous systems of operators, affecting their health.

[0003] Existing treatment devices mostly use wet scrubbers or water curtain methods to treat dust, but the wastewater containing explosives needs to be treated afterwards, which increases the amount of wastewater to be treated and the cost. The explosive components in the wastewater cannot be rationally utilized during recycling, which will also lead to a waste of resources.

[0004] An existing patent (publication number: CN209439170U) discloses an automatic dust removal device for powdered explosives. When the charging machine is in use, it generates a large amount of dust. The upper end of the charging machine is equipped with a dust removal port, which is connected to a transmission pipe. The other end of the transmission pipe is connected to one end of an explosion-proof fan, and the other end of the explosion-proof fan is connected to a dust collector. The dust generated by the explosion-proof fan is attracted to the dust collector for recycling through the guiding force of the charging machine. This device has a good dust removal effect and the dust can be recycled, which improves the utilization rate of resources.

[0005] To address the aforementioned problems, existing patents offer solutions, but their screening effects are unsatisfactory. During the dust collection process, energetic material dust with different particle sizes and compositions requires different treatment methods for recycling. Due to the lack of effective screening, it is impossible to finely filter and classify the dust, which greatly limits the subsequent dust treatment and reuse, making it difficult to achieve efficient and safe resource utilization, resulting in potential resource waste and reducing the practicality of the device.

[0006] Therefore, a dust recovery structure for energetic material processing is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A dust recovery structure for energetic material processing includes a box 1, a screening component 2 fixedly connected inside the box 1, and a dust collection component 3 fixedly connected to the top of the box 1. The dust collection component 3 includes a connecting hose 301, an explosion-proof fan 302 fixedly connected to the left side of the connecting hose 301, and a dust collection plate 303 fixedly connected to the side of the explosion-proof fan 302 away from the connecting hose 301.

[0029] The screening component 2 includes a U-shaped block 201. Hydraulic cylinders 202 are fixedly connected to the front and rear sides of the top of the U-shaped block 201. Several buffers 203 are fixedly connected to the bottom of the U-shaped block 201. Several sliders 204 are movably connected to the front and rear sides of the inner wall of the U-shaped block 201. A filter box 205 is fixedly connected between the opposite sides of two sliders 204.

[0030] In this embodiment: the use of bolt 306 and L-shaped plate 305 allows bolt 306 to pass through L-shaped plate 305 and be threaded to other equipment, making the dust collection plate 303 more securely fixed and preparing for dust collection. Simultaneously, the explosion-proof fan 302 generates suction, causing dust generated during processing to flow smoothly into the discharge plate 304 through the connecting hose 301. The dust is then evenly sprayed into the filter box 205 by the discharge plate 304, achieving dust collection and improving the ease of use of the dust collection assembly 3. Finally, under the action of the three filter boxes 205, the dust is sequentially... The dust flows through three filter boxes 205, achieving fine filtration and classification of dust, avoiding potential safety issues during mixed dust processing, ensuring full utilization of resources, and improving dust recovery efficiency. Under the action of the hydraulic cylinder 202, the U-shaped block 201 and filter box 205 can be moved and the buffer 203 can be compressed. At the same time, under the action of the buffer 203, the impact force generated when the U-shaped block 201 falls can be dispersed, enabling the filter box 205 to vibrate moderately, preventing dust from clogging the filter box 205, ensuring the screening effect of the screening component 2, and improving the ease of use of the device.

[0031] Specifically, such as Figure 4 As shown, the connecting hose 301 extends into the interior of the housing 1 on the side away from the explosion-proof fan 302 and is fixedly connected to the discharge plate 304, and the discharge plate 304 is located on top of the U-shaped block 201.

[0032] Specifically, such as Figure 4 As shown, L-shaped plates 305 are fixedly connected to both the front and rear sides of the dust collection plate 303, and several bolts 306 are threadedly connected to the inside of the L-shaped plates 305.

[0033] Specifically, such as Figure 3As shown, the top of the housing 1 is provided with a connection hole 4 for use with the connecting hose 301, and the surface of the connecting hose 301 is in contact with the inner wall of the connection hole 4.

[0034] In this embodiment: by using the connecting hose 301 in conjunction with the connecting hole 4, the surface of the connecting hose 301 contacts the inner wall of the connecting hole 4, so that the connecting hose 301 can be tightly connected to the housing 1. This allows dust to flow smoothly into the housing 1 through the connecting hose 301 for subsequent operations, avoiding dust leakage and improving the stability of the dust collection component 3.

[0035] Specifically, such as Figure 5 As shown, there are three filter boxes 205 stacked inside the U-shaped block 201, and the filtration effect of the three filter boxes 205 increases sequentially from top to bottom.

[0036] Specifically, such as Figure 5 As shown, the front and rear sides of the inner wall of the U-shaped block 201 are provided with several grooves 5 for use with the slider 204, and the inside of the groove 5 is fixedly connected to the positioning plate 6. The right side of the positioning plate 6 is rotatably connected to the buckle block 7, and the slider 204 is movably connected to the surface of the positioning plate 6.

[0037] In this embodiment: the three filter boxes 205 work together to allow dust to flow through them sequentially, achieving fine filtration and classification of the dust. This avoids potential safety issues during mixed dust processing, enabling efficient and safe resource utilization and improving dust recovery efficiency. Then, the slider 204 works in conjunction with the chute 5, allowing the slider 204 to move smoothly within the chute 5 under the constraint of the positioning plate 6. This simultaneously drives the filter boxes 205 to move smoothly, facilitating the loading and unloading of the filter boxes 205 and simplifying subsequent dust processing. Simultaneously, the latching block 7 secures the slider 204, making the connection between the filter boxes 205 and the U-shaped block 201 more robust. This prevents the filter boxes 205 from shaking or shifting during screening, ensuring the normal operation of the screening assembly 2 and improving its ease of use.

[0038] Specifically, such as Figure 2 , Figure 3 As shown, a movable door 8 is fixedly connected to the right side of the box 1, and a rubber sealing strip 9 is fixedly connected to the side of the movable door 8 closest to the box 1.

[0039] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a controller 10 is fixedly connected to the side of the movable door 8 away from the box 1, and the controller 10 is electrically connected to the dust collection assembly 3 and the screening assembly 2.

[0040] In this embodiment: the movable door 8 allows the housing 1 to be opened smoothly, enabling the filter box 205 to be extracted smoothly. This allows for subsequent processing of the dust and maintenance / replacement of the filter box 205, ensuring the normal operation of the screening component 2. Simultaneously, the rubber sealing strip 9 fills the gap between the movable door 8 and the housing 1, preventing moisture and dust from seeping into the housing 1 and avoiding dust contamination due to moisture or impurities, thus ensuring dust quality and improving the practicality of the device. Then, under the control of the controller 10, the operation of the dust collection component 3 and the screening component 2 can be precisely controlled. The explosion-proof fan 302 can be precisely controlled to collect dust. Simultaneously, the hydraulic cylinder 202 is activated, driving the U-shaped block 201 to move smoothly and compress the buffer 203, thereby vibrating the filter box 205 to prevent dust from clogging it, ensuring the screening effect of the screening component 2 and improving the ease of use of the device.

[0041] Working Principle: When processing energetic materials, the bolt 306 is first used in conjunction with the L-shaped plate 305 to thread the bolt through the L-shaped plate 305 and connect it to other equipment. This ensures the dust collection plate 303 is securely fixed, preparing for dust collection. Then, the operator can precisely control the operation of the dust collection component 3 and the screening component 2 via the controller 10. During dust collection, the explosion-proof fan 302 is activated, generating strong suction and creating a negative pressure environment in the processing area. This allows the dust generated during processing to flow smoothly into the discharge plate 304 through the connecting hose 301. The dust is then evenly sprayed into the filter box 205 by the discharge plate 304, achieving dust collection. After dust collection, the crucial screening stage begins. The three filter boxes 205 work together to allow the dust to flow through them sequentially, achieving fine filtration and classification of the dust. This avoids potential safety issues during mixed dust processing and ensures full resource utilization. During the dust screening process, the controller 10 activates... The hydraulic cylinder 202 drives the U-shaped block 201 and the filter box 205 to move and compress the buffer 203. At the same time, under the action of the buffer 203, the impact force generated when the U-shaped block 201 falls can be dispersed, which can make the filter box 205 vibrate moderately, avoid dust clogging the filter box 205, and ensure the screening effect of the screening component 2. Finally, after the energetic material is processed, the operator opens the movable door 8. The rubber sealing strip 9 between the movable door 8 and the box 1 ensures the sealing of the equipment under normal conditions. Then, the buckle block 7 is rotated to release its restriction on the slider 204, so that the filter box 205 can move smoothly under the restriction of the positioning plate 6. The filter box 205 can be smoothly pulled out, which can not only treat the dust in it, but also maintain and replace the filter box 205, ensuring the screening effect of the screening component 2. Then, the filter box 205 is reset and the buckle block 7 is rotated to lock the slider 204, realizing the reinstallation of the screening component 2, preparing for the subsequent dust recovery screening work, and ensuring the sustainable and stable operation of the equipment.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
