Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust removal device for expanded explosives. Background Technology

[0002] Extruded explosives are a type of industrial mixed explosive widely used in large-scale, efficient, and economical blasting operations, commonly found in mining, infrastructure construction, and other fields.

[0003] The current loading process of a drug loading machine typically involves pumping material into a weighing hopper. Once the set weight is reached, the pumping stops and the weighing hopper's discharge gate opens. The material then falls into a bag fitted over the discharge port under gravity for further sealing. However, dust is easily generated during the process of the material falling into the bag, causing large particles and heavier powder to backflow into the dust collection pipeline and interfere with the operation of the pneumatic valves installed in the pipeline. The large mass of powder is difficult to be sucked away by the dust collection fan, causing some of the large mass of powder to accumulate in the dust collection pipeline and block it, thus affecting work efficiency. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a dust removal device for expanded explosives, thereby reducing the backflow of explosive powder into the dust removal pipeline, thus reducing the probability of pipeline blockage and ensuring work efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a dust removal device for expanded explosives, comprising: a dust removal pipeline, a switching valve and a dustproof plate connected to the recovery unit; The dust removal pipeline includes a conveying pipe installed on one side of the loading machine, and a branch pipe connecting the conveying pipe and the loading machine; The conveying pipe is used to transport the dust that has fallen into the loading machine to the recycling section; The switching valve is installed inside the branch pipe and is used to open and close the branch pipe; The dustproof plate is installed at the connection between the branch pipe and the loading machine to prevent dust from entering the branch pipe.

[0006] Furthermore, the delivery pipes are provided on both sides of the loading machine, and each delivery pipe is provided with a branch pipe that communicates with the loading machine; Each of the branch pipes is equipped with the switch valve, and each of the branch pipes is equipped with a dustproof plate at the connection port with the loading machine; The dust removal pipeline also includes a collection pipe, one end of which is connected to each of the conveying pipes for centralized conveying of dust to the recovery section.

[0007] Furthermore, each of the aforementioned dustproof plates is respectively installed on one side of the corresponding discharge gate of the hopper; Each material discharge gate is equipped with a cleaning brush corresponding to the dustproof plate.

[0008] Furthermore, the manifold is also equipped with a purging component, including an air supply pipe and multiple air nozzles; The gas supply pipe is connected to an external gas source and is used to supply airflow to each of the gas nozzles; The air outlet of each of the air nozzles is inserted into the manifold to blow away the dust adhering to the inner wall of the manifold.

[0009] Furthermore, the air outlet of each of the air nozzles is tangent to the cross-section of the inner wall of the manifold.

[0010] The beneficial effects of this utility model are reflected in: This invention features a switch valve that opens the branch pipe to improve the efficiency of vacuuming during bagging. During the filling process, the switch valve closes the branch pipe to concentrate the airflow in the delivery pipe. Since the switch valve is located inside the branch pipe, it reduces the contact between dust in the delivery pipe and the switch valve. Furthermore, the dustproof plate prevents dust from flowing back from the branch pipe into the delivery pipe and causing blockages, thus reducing the probability of blockages. At the same time, the dustproof plate prevents dust inside the filling machine from contacting the switch valve, ensuring the stability of the switch valve's operation while improving work efficiency.

[0013] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0014] Please see Figure 1-4 This utility model discloses a dust removal device for expanded explosives, including: a dust removal pipeline 1 connected to a recovery unit (not shown in the figure), a switching valve 2 and a dustproof plate 3; The dust removal pipeline 1 includes a conveying pipe 11 located on one side of the loading machine 01, and a branch pipe 12 connecting the main conveying pipe 11 and the loading machine 01. The recovery section extracts the dust that has fallen into the loading machine 01 through the conveying pipe 11. The air inlet of the branch pipe 12 is set at a higher height than the air inlet of the conveying pipe 11, and is used to draw air from the bag 02; The switch valve 2 is installed inside the branch pipe 12 and is used to control the opening and closing of the branch pipe 12; The dustproof plate 3 is installed at the connection between the branch pipe 12 and the loading machine 01 to prevent dust from entering the branch pipe 12.

[0015] In practice, before loading the medicine, the dust removal fan of the recovery section is started, and the switch valve 2 is opened at the same time. Due to the airtightness of the medicine loading machine 01, the air in the bag 02 is blown out of the medicine loading machine 01 through the conveying pipe 11 and the branch pipe 12 to avoid too much air in the bag, which would cause excessive dust to be generated when discharging the material. During loading, all discharge gates of the hopper are opened, and the material enters the bag 02 under gravity. At the same time, all switch valves 2 are closed, so that the air force can be concentrated at the air inlet of the conveying pipe 11, reducing the dust from escaping from the equipment. Each dustproof plate 3 prevents the dust from contacting the switch valves 2 and also prevents the dust from entering the conveying pipe 11 through the branch pipe 12, ensuring that the switch valves 2 work smoothly. Subsequently, the dust is transported to the recycling department through the conveying pipe 11 for unified treatment.

[0016] In this invention, the switch valve 2 opens the branch pipe 12 to improve the working efficiency of vacuuming the bag 02; during the filling process, the switch valve 2 closes the branch pipe 12 to concentrate the airflow in the conveying pipe 11. Since the switch valve 2 is located inside the branch pipe 12, it reduces the contact between dust in the conveying pipe 11 and the switch valve 2. The dustproof plate 3 prevents dust from backflowing from the branch pipe 12 into the conveying pipe 11 and causing blockage, thus reducing the probability of blockage in the conveying pipe 11. At the same time, the dustproof plate 3 prevents dust inside the filling machine 01 from contacting the switch valve 2, ensuring the working stability of the switch valve 2 while improving working efficiency.

[0017] Preferably, the switching valve 2 can be a pneumatic switching valve 2 from the prior art.

[0018] In one embodiment, the loading machine 01 is provided with conveying pipes 11 on both sides, and each conveying pipe 11 is provided with a branch pipe 12 that communicates with the loading machine 01. Each branch pipe 12 is equipped with a switch valve 2, and each branch pipe 12 is equipped with a dustproof plate 3 at the connection port with the loading machine 01. The dust removal pipeline 1 also includes a collection pipe 13, one end of which is connected to each conveying pipe 11 for centralized conveying of dust to the recycling section.

[0019] With this design, when recovering dust, each conveying pipe 11 attracts the dust in the loading machine 01 until the dust is guided into the collecting pipe 13. Compared with the traditional dust storage bin, the cross-sectional change of the flow channel in the collecting pipe 13 is smaller, thereby reducing the impact of changes in airflow velocity and making it less likely for dust to accumulate in the collecting pipe 13.

[0020] In one embodiment, each dustproof plate 3 is disposed on one side of the corresponding discharge gate of the hopper; Each feeding gate is equipped with a cleaning brush 4 corresponding to the corresponding dustproof plate 3. When the feeding gate rotates, it is used to drive the corresponding cleaning brush 4 to move towards the corresponding dustproof plate 3.

[0021] With this design, when the hopper is unloading, each discharge gate opens and drives the corresponding cleaning brush 4 to rotate towards the corresponding dustproof plate 3 until the cleaning brush 4 contacts the dustproof plate 3 and cleans its dustproof surface. When the opening and closing pipe is closed, each cleaning brush 4 passes through the corresponding dustproof plate 3 again and cleans it, so as to reduce the clogging of the dustproof plate 3.

[0022] It should be noted that each cleaning brush 4 is a soft brush, and each feeding gate drives the cleaning brush 4 to move slowly and at a low frequency. The friction generated when each brush comes into contact with the dustproof plate 3 will not affect the stability of the dust.

[0023] It should be noted that the structure and function of the feeding gate are common knowledge to those skilled in the art, so they will not be described in detail here.

[0024] In one embodiment, the manifold 13 is further provided with a purging component 5, including an air supply pipe 51 disposed on one side of the manifold 13 and connected to an external air source (not shown in the figure); The gas supply pipe 51 is also evenly distributed with multiple air nozzles 52. The outlet of each air nozzle 52 is inserted into the manifold 13, and the connection between each air nozzle 52 and the manifold 13 is a dynamic seal connection. The gas supply pipe 51 delivers airflow into the manifold 13 by supplying air to each gas nozzle 52.

[0025] With this design, when the manifold 13 needs to be cleaned, the air source delivers airflow to the air supply pipe 51 and blows it out into the manifold 13 through each air nozzle 52, thereby blowing away the dust adhering to the inner wall of the manifold 13.

[0026] In one embodiment, the air outlets of each nozzle 52 are tangential to the cross-section of the inner wall of the manifold 13 to improve purging efficiency.

[0027] With this design, when each nozzle 52 delivers airflow into the manifold 13, the airflow adheres to the wall and flows tangentially, thereby causing the airflow to be delivered in a spiral shape in the manifold 13, increasing the purging area, and thus further improving the purging efficiency.

[0028] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0029] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0030] Additionally, "multiple" refers to two or more.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
