[0002] In blasting engineering, bulk explosives, as an efficient and flexible form of explosives, are widely used in various scenarios such as open-pit mines and underground mines. In actual operations, bulk explosives require mixing operations. Currently, the proportioning method of bulk explosives mainly relies on the combination of mechanical mixing and manual control. Specifically: explosive raw materials are added to the bin of the mixing truck according to a predetermined ratio, and are preliminarily mixed by a mechanical stirring device. Subsequently, when the mixing truck travels to the blasting site, the mixed bulk explosives are transported into the blast holes.

Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by this application.

[0029] Since there is manual participation in the control during the proportioning process, it is difficult to ensure the metering accuracy. In addition, the existence of manual control factors also increases the possibility of errors, making it difficult to meet the requirements for the proportioning of each component of the explosive, thereby affecting the accuracy of the explosive proportioning, and ultimately resulting in the mixed explosive prepared not being able to meet the specific requirements of the blasting operation.

[0030] Based on this, the present application provides a high-precision metering and proportioning device for mixed explosives. Through the cooperation of various components, the automatic proportioning of mixed explosives can be achieved, without the need for manual participation in the proportioning of the raw materials of mixed explosives, reducing or avoiding errors caused by human factors, enabling the proportioning of each component of the explosive to meet the requirements, improving the accuracy of the proportioning of mixed explosives, and thus making the proportioned mixed explosives meet the specific requirements of blasting operations.

[0031] Please refer to Figures 1 to 2 , the present application provides a high-precision metering and proportioning device for mixed explosives, including: a storage bin 2, an opening and closing component, a hoisting weighing device 4, a loading component, a vibrating screen feeder 9, a mixing tank body, a stirring component, and a control module 1; the opening and closing component, the hoisting weighing device 4, the loading component, and the stirring component are all connected to the control module 1. The storage bin 2 is provided with a plurality of accommodating cavities 12, and the accommodating cavities 12 are used for placing the raw materials of mixed explosives. The opening and closing component is installed at the lower opening of the storage bin 2, the hoisting weighing device 4 is arranged below the opening and closing component, the loading component is connected to the hoisting weighing device 4, and the loading component cooperates with the hoisting weighing device 4 to weigh the mixed explosives. The vibrating screen feeder 9 is arranged below the loading component, the mixing tank body is arranged on one side of the loading component, and the stirring component is installed inside the mixing tank body. The stirring component cooperates with the mixing tank body to mix the weighed raw materials of the mixed explosives.

[0032] First, the functions of each component are introduced:

[0033] Storage bin 2: A plurality of accommodating cavities 12 are arranged in the storage bin 2. The inner wall of the accommodating cavity 12 is set as a smooth surface. Different accommodating cavities 12 store different types of explosive raw materials, such as oxidants, combustibles, additives, etc. The raw materials stored inside the accommodating cavity 12 are not limited here and can be set according to actual situations.

[0034] Opening and closing component: Used to open or close the outlet of the storage bin 2. When raw materials need to be put in, the control module 1 sends a signal to the opening and closing component, and the opening and closing component opens. The raw materials fall into the hoisting weighing device 4 below under the action of gravity. Once the preset weight is reached, the door panel quickly closes to prevent excessive feeding of raw materials.

[0035] Hoisting weighing device 4: The hoisting weighing device 4 measures the gravity of the raw materials on the loading component, converts it into an electrical signal, and transmits it to the control module 1. The hoisting weighing device 4 can display the weight of the raw materials in real time and compare it with the preset proportion. If the weight is insufficient or exceeds the standard, the control module 1 will send a signal to the opening and closing component to adjust the feeding amount of the raw materials through the opening and closing component until the required weight is reached.

[0036] Material loading component: It is used to carry the raw materials flowing out of the storage bin 2 and transport the measured raw materials to the vibrating sieve feeder 9.

[0037] Vibrating sieve feeder 9: The vibrating sieve feeder 9 generates high-frequency vibrations, causing the raw materials to continuously jump and roll. Under the action of the vibrating sieve feeder 9, the raw materials can be driven to vibrate. After the raw materials are vibrated, they are then transported to the mixing tank body.

[0038] Mixing tank body: The mixing tank body is made of stainless steel or explosion-proof alloy, providing a mixing space for various raw materials. Under the action of the stirring component, various raw materials rotate and flip in the mixing tank body, enabling the raw materials to fully contact and mix in the mixing tank body to form a uniform explosive mixture. After mixing is completed, the mixture can be discharged through the discharge port at the bottom or further processed.

[0039] Stirring component: The stirring component rotates or flips in the mixing tank body, and the operation of the stirring component ensures the uniform mixing of the raw materials in the mixing tank body.

[0040] Control module 1: Receives sensor signals and operation instructions from various components, performs data processing and decision-making according to preset programs and parameters, and then sends control signals to various components to perform corresponding actions. The control module 1 realizes the automatic control and intelligent monitoring of the entire device. It can automatically adjust the operating states of the opening and closing component, the hoisting weighing device 4, the material loading component, the vibrating sieve feeder 9, and the stirring component according to parameters such as the ratio requirements of the raw materials, the mixing time, and the mixing speed, ensuring the accuracy and consistency of the explosive ratio.

[0041] Overall working principle of the device:

[0042] Raw material preparation: Different types of explosive raw materials are stored in different accommodation cavities 12 of the storage bin 2 respectively, and their tightness and safety are ensured.

[0043] Raw material feeding and weighing: According to the requirements of the explosive ratio, the control module 1 instructs the opening and closing component to open the outlet of the corresponding cavity, and the raw materials fall into the material loading component and are precisely weighed by the hoisting weighing device 4. When the preset weight is reached, the opening and closing component quickly closes.

[0044] Raw material screening: The weighed raw materials are transported by the material loading component to the vibrating sieve feeder 9 for vibration treatment, and the vibrating sieve feeder 9 is used to ensure the uniformity and fineness of the raw materials through vibration treatment.

[0045] Raw material mixing: The vibration-treated raw materials are sent into the mixing tank body. The control module 1 starts the stirring motor 10 of the stirring component, driving the stirring rod 11 to rotate or flip in the mixing tank body. The raw materials are fully contacted and mixed under the action of the stirring rod 11 to form a uniform explosive mixture.

[0046] Mixture discharge: After the mixing is completed, the mixture can be discharged through the discharge port at the bottom of the mixing tank or further processed. Through the above control and coordinated work, the equipment realizes the accurate metering, screening, mixing and proportioning of explosive raw materials, improves the quality and performance of explosives, and at the same time reduces the complexity and risk of manual operation.

[0047] Optionally, the opening and closing assembly includes a fixed plate 3, a rotating shaft 6 and a fitting plate 5. The rotating shaft 6 is connected to the control module 1. The fixed plate 3 is installed at the lower end of the storage bin 2. An opening is provided on the fixed plate 3 corresponding to the accommodating cavity 12. One end of the rotating shaft 6 is fixed to the lower end of the fixed plate 3, and the other end of the rotating shaft 6 is connected to the fitting plate 5. The fitting plate 5 is in contact with the fixed plate 3.

[0048] In the embodiment of the present application, the opening and closing assembly includes a fixed plate 3, a rotating shaft 6 and a fitting plate 5. The fixed plate 3 is a solid flat plate installed at the lower end of the storage bin 2 as the base of the opening and closing assembly. An opening is provided on the fixed plate 3 corresponding to each accommodating cavity 12. The size and position of these openings match the outlet of the accommodating cavity 12 to ensure that the raw materials can pass through accurately. At the same time, the fixed plate 3 also provides an installation position for the rotating shaft 6, enabling the rotating shaft 6 to be stably fixed thereon. The rotating shaft 6 is a cylindrical rod, one end of which is fixed to the lower end of the fixed plate 3 through a bearing, and the other end is connected to the fitting plate 5. The rotating shaft 6 is connected to the control module 1 and receives instructions from the control module 1. When raw materials need to be put in, the control module 1 sends a signal to the rotating shaft 6 to drive it to rotate. The rotation of the rotating shaft 6 drives the fitting plate 5 to move relative to the fixed plate 3, thereby opening or closing the opening.

[0049] Specifically, the fitting plate 5 is a flat plate similar in shape and size to the fixed plate 3. The function of the fitting plate 5 is to cooperate with the fixed plate 3 to open and close the opening. When the rotating shaft 6 rotates, the fitting plate 5 will move relative to the fixed plate 3, thereby opening or covering the opening. When the fitting plate 5 is in close contact with the fixed plate 3, a sealing barrier is formed between them to prevent raw material leakage and impurity entry.

[0050] By controlling the rotation angle and speed of the rotating shaft 6, the size and time of the opening between the fitting plate 5 and the fixed plate 3 can be accurately controlled, so as to ensure that the amount of raw materials put in meets the preset proportion requirements. And when the fitting plate 5 is in close contact with the fixed plate 3, a sealing barrier is formed between the fitting plate 5 and the fixed plate 3.

[0051] Optionally, a slot is provided on the fitting plate 5. The area of the slot is larger than the area of the opening and smaller than the area of the region between two openings.

[0052] In the embodiment of the present application, the slot is a groove machined on the fitting plate 5, and its shape is usually rectangular, circular or a shape customized according to specific requirements. The area of the slot is larger than the opening area of the corresponding accommodating cavity 12 on the lower fixing plate 3 of the storage bin 2, but smaller than the area between two adjacent openings. The position of the slot corresponds to the opening on the fixing plate 3 and is usually located in the part of the fitting plate 5 covering the opening. This layout ensures that when the fitting plate 5 is attached to the fixing plate 3, the slot can accurately align with the opening to form a channel for raw material feeding.

[0053] Since the area of the slot is larger than the area of the opening, it can play an accurate guiding role during the raw material feeding process. When the rotating shaft 6 drives the fitting plate 5 to move to open the opening, the raw material will slide along the edge of the slot to the weighing system below, reducing the scattering and waste of the raw material.

[0054] Optionally, a fixing rod is installed at the lower end of the opening and closing assembly, the hoisting weigher 4 is installed on the fixing rod, the loading component is connected to the hoisting weigher 4, the loading component includes a loading platform 7 and an electric control board 8 body, a hole is provided on the loading platform 7, and the electric control board 8 body is arranged at the lower end of the hole, and the electric control board 8 body is used to control the closing and opening of the hole.

[0055] In the embodiment of the present application, a fixing rod is installed at the lower end of the opening and closing assembly. The fixing rod provides a stable installation foundation for the hoisting weigher 4. The fixing rod can bear the weight and vibration of the hoisting weigher 4 and the loading component. Among them, the hoisting weigher 4 is installed on the fixing rod and is located below the opening and closing assembly, and the raw material is weighed in real time by the hoisting weigher 4.

[0056] Among them, the loading component includes two parts, a loading platform 7 and an electric control board 8 body. The loading platform 7 is a flat table for carrying raw materials. A hole is provided on the platform, and the hole corresponds to the electric control board 8 body below. The electric control board 8 body is arranged at the lower end of the hole. The electric control board 8 body is connected to the control module 1, and the closing and opening of the hole are controlled by the electric control board 8 body.

[0057] After weighing the raw materials on the loading platform 7 by the hoisting weigher 4, if the weight of the raw materials reaches the requirement, the control module 1 will send a signal to the electric control board 8 body to drive it to open the corresponding hole. At this time, the weighed raw materials will fall from the hole of the loading platform 7 into the vibrating sieve 9 below. When the raw material feeding is completed, the electric control board 8 body will close the hole again and wait for the next feeding operation.

[0058] Optionally, the loading platform 7 is set in a U-shaped or V-shaped shape.

[0059] In the embodiment of the present application, the U-shaped loading platform 7 has the characteristics of being high on both sides and low in the middle, forming a structure similar to a trough. The U-shape helps to concentrate the raw materials in the central area of the loading platform 7, facilitating subsequent processing. The U-shaped platform can reduce the scattering and splashing of the raw materials on the loading platform 7 and improve the collection efficiency of the raw materials. At the same time, when the raw materials fall from the storage bin 2 onto the platform, the U-shaped trough can guide the raw materials to flow towards the center, preventing uneven accumulation of the raw materials on the platform or slipping to the edge of the platform.

[0060] Among them, the V-shaped loading platform 7 shows a trend of gradually sloping downwards on both sides to the center, forming a sharp bottom. Similarly, the V-shape makes it easier for the raw materials to converge to the central position on the platform. It should be noted that the loading platform 7 can also be set to other shapes, which are not specifically limited here and can be set according to the actual situation.

[0061] Optionally, the mixing assembly includes a mixing motor 10 and mixing rods 11. The mixing motor 10 is installed inside the mixing tank body. The mixing motor 10 is connected to the mixing rods 11, and the mixing motor 10 is used to drive the mixing rods 11 to rotate inside the mixing tank body.

[0062] In the embodiment of the present application, the mixing assembly can ensure that the raw materials are fully mixed to achieve a uniform proportion relationship. Specifically, the mixing motor 10 is installed inside the mixing tank body. The mixing motor 10 can drive the mixing rods 11 to work, reducing the energy loss during the transmission process. The mixing rods 11 are determined according to the shape, size, and raw material characteristics of the mixing tank body, and accessories such as mixing blades and scrapers are equipped on the mixing rods 11 to enhance the mixing effect. The shape and layout of the mixing rods 11 can cover the entire inside of the mixing tank body to achieve all-round and dead-angle-free mixing of the raw materials.

[0063] Specifically, driven by the mixing motor 10, the mixing rods 11 rotate at a high speed inside the mixing tank body. During this process, accessories such as mixing blades and scrapers will continuously scrape the inner wall and bottom of the tank, lift the raw materials from all corners and mix them fully with other raw materials. In this way, the mixing assembly can achieve uniform mixing and full reaction of the raw materials, ensuring the quality and performance of the explosive products.

[0064] Optionally, a sampling port and a discharge port are provided on the mixing tank body, and the sampling port is arranged above the discharge port.

[0065] In the embodiments of the present application, the sampling port is provided on the side wall or the top of the mixing tank, and is usually located above the discharge port. The main purpose of the sampling port is to allow the operator to safely take out a certain amount of the mixed raw materials for testing without fully opening the mixing tank. Through sampling analysis, the mixing state of the raw materials, the reaction progress and the product performance can be monitored in real time, so as to adjust the production parameters in time to ensure the product quality. Among them, the discharge port is usually located at the bottom or a lower position on the side of the mixing tank to facilitate the smooth discharge of the uniformly mixed raw materials.

[0066] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
