Description

Technical Field

[0001] The invention relates to the technical field of explosive detection, in particular to a real-time visual detection device for dynamic viscosity of explosive. Background Art

[0002] Melt-cast charge is a method of charging by injecting molten explosive into a projectile or mold, which solidifies into an explosive column of a certain shape and size after cooling for a period of time. It is one of the most important charging methods for warheads at present, and its process is widely used because it is not restricted by the shape of the inner cavity of the projectile mold. The production of melt-cast charge mainly includes three process stages: mixing, injection and cooling and solidification. Among them, the mixing stage mainly affects the flow characteristics and component uniformity of the slurry, and plays a fundamental role in the quality of subsequent processes. By measuring the viscosity information of the explosive slurry, it can be used as an effective indicator to judge the quality of the mixing process.

[0003] Traditional viscosity testing instruments such as capillary viscometers and rotational rheometers are all offline measuring devices that require manual sampling, making it difficult to achieve zero-contact testing and real-time testing between workers and explosives, which poses a safety risk. In addition, from the extraction of explosives to testing, the use of traditional viscosity testing methods or traditional viscosity testing instruments is usually difficult to ensure the consistency of the environmental state with the state in the explosive mixing device, resulting in deviations between the test data of the extracted explosives and the actual data, making it difficult to effectively guide the research and development of the mixing process, and easily resulting in long mixing time and low production efficiency; or too short mixing time, the explosive slurry is not fully mixed, and the components in the explosive slurry are uneven, affecting the performance and safety of the formed explosives.

DETAILED DESCRIPTION

[0033] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] Preferably, the number of the constant temperature flow channel components 3 in the present invention is eight groups, and the eight groups of constant temperature flow channel components 3 are circumferentially connected to the flow channel automatic replacement component 4. After the explosive slurry is extracted and the detection is completed, the eight groups of constant temperature flow channel components 3 can be disassembled and cleaned.

[0037] The present invention provides a device capable of real-time online detection of the dynamic viscosity of explosives by setting an explosive stirring component 1, two valve control components 2, multiple groups of constant temperature flow channel components 3, automatic flow channel replacement components 4, visual recognition detection components 5 and base support components 6. The device can realize zero-contact detection between the staff and the explosive slurry, and can perform real-time online detection during the stirring and mixing process of the explosive slurry under the cooperation of the flow channel constant temperature flow channel component 3, the flow channel automatic replacement component 4 and the visual recognition detection component 5, so as to ensure the consistency of the state of the extracted explosive slurry with the state in the explosive stirring component 1 and the real-time detection to the greatest extent, and avoid the deviation of the detection structure data. In addition, by setting multiple groups of flow channel constant temperature flow channel components 3, the extraction and detection of explosive slurry can be performed multiple times during the detection process, and the situation that the detection data is biased due to repeated use of the same group of constant temperature flow channel components 3 can be avoided, thereby improving the accuracy of the dynamic viscosity detection of the explosive slurry.

[0038] Optionally, each group of the constant temperature flow channel assembly 3 includes a flow channel docking port 301, two liquid delivery pipes 302, a viscosity detection flow channel 303, a water inlet 304, an air pressure balance flow channel 305, a shell 306 and a water outlet 307, one end of the flow channel docking port 301 is connected to the viscosity detection flow channel 303, the other end of the flow channel docking port 301 is used to connect to the explosive stirring assembly 1, one end of the two liquid delivery pipes 302 is respectively connected to the water inlet 304 and the water outlet 307, the other ends of the two liquid delivery pipes 302 are connected to the external water supply and heating equipment, the viscosity detection flow channel 303 is connected to the The air pressure balancing channel 305 is installed in the shell 306, one end of the air pressure balancing channel 305 is connected to one end of the viscosity detection channel 303, the other end of the air pressure balancing channel 305 extends to the outside of the shell 306, the other end of the viscosity detection channel 303 is connected to the lower side of the other end of the air pressure balancing channel 305, the water inlet 304 is opened at the bottom of the shell 306, and the water outlet 307 is opened at the top of the shell 306; the bottoms of multiple shells 306 in multiple groups of constant temperature flow channel assemblies 3 can be slidably connected to the flow channel automatic replacement assembly 4.

[0039] In a specific embodiment, the viscosity detection channel 303 is fixed to the inner wall of the housing 306 by a rubber ring, and the viscosity detection channel 303 can be removed by plugging and unplugging. A silicone pad is glued to the bottom of the housing 306 to prevent the housing 306 from being broken due to collision.

[0040] The other ends of the two liquid delivery pipes 302 are connected to the external water supply and heating equipment, so that the hot water in the external water supply and heating equipment continuously enters the shell 306 from the water inlet 304 through a liquid delivery pipe 302. After the hot water fills the shell 306, it enters the external water supply and heating equipment through the water outlet 307 and the other liquid delivery pipe 302, realizing the circulation of hot water inside the shell 306, ensuring that the periphery of the viscosity detection flow channel 303 and the air pressure balance flow channel 305 is in a constant temperature state, and ensuring as much as possible that the state of the explosive slurry extracted is consistent with the state in the explosive stirring assembly 1.

[0041] Optionally, the viscosity detection channel 303 includes two pipes 3031, an upper ball tube 3032 and a lower ball tube 3033, the bottom end of the upper ball tube 3032 is connected to the top end of the lower ball tube 3033, the bottom end of the lower ball tube 3033 is connected to one end of one of the pipes 3031, the other end of one of the pipes 3031 is connected to one end of the air pressure balance channel 305, the top end of the upper ball tube 3032 is connected to one end of another pipe 3031, and the other end of the other pipe 3031 is connected to the lower side of the other end of the air pressure balance channel 305.

[0042] In a specific implementation, after the explosive slurry is drawn into another pipe 3031 through the flow channel docking port 301, the explosive slurry flows to the upper ball tube 3032. The process of the explosive slurry flowing from the upper ball tube 3032 to the lower ball tube 3033 can reflect the flow state of the explosive slurry, so that the state of the explosive slurry photographed by the visual recognition detection component 5 is accurate.

[0043] Optionally, the flow channel automatic replacement component 4 includes a rotating structure 401, a plurality of slide grooves 402, a plurality of limiting structures 403, a supporting structure 404, a bottom moving structure 405, four wheel axles 406, four power wheels 407, a first motor and a second motor, the outer circumference of the rotating structure 401 is connected to the plurality of slide grooves 402, the plurality of limiting structures 403 are respectively connected to the bottom of the plurality of shells 306, and the plurality of limiting structures 403 are respectively slidably connected to the plurality of slide grooves 402, the bottom of the rotating structure 401 is provided with a first blind hole, and the top of the supporting structure 404 is provided with a In the first blind hole, the bottom surface of the supporting structure 404 is connected to the top surface of the bottom moving structure 405, the four axles 406 are respectively connected to the four corners of the bottom of the bottom moving structure 405, the four power wheels 407 are respectively connected to the four axles 406, a second blind hole is opened on the top of the supporting structure 404, the first motor is fixed in the second blind hole, the output shaft of the first motor is connected to the bottom of the rotating structure 401, the second motor is fixed to the bottom of the bottom moving structure 405, and the output shaft of the second motor is connected to the four axles 406.

[0044] Specifically, the first motor and the second motor may be started or stopped by manual control, or the first motor and the second motor may be started or stopped by the remote data processor 504 after being electrically connected to the remote data processor 504 .

[0045] The number of the slide grooves 402 and the limiting structures 403 in the present invention is consistent with that of the constant temperature flow channel assembly 3, that is, the present invention is provided with eight slide grooves 402 and eight limiting structures 403. The outer peripheries of the four power wheels 407 are all glued with rubber rings to increase the friction of the power wheels 407 on the rolling surface. The eight slide grooves 402 are all circumferentially fixed to the outer periphery of the rotating structure 401 by welding. The bottom of the support structure 404 is fixedly connected to the top surface of the bottom moving structure 405 by bolts.

[0046] In a specific implementation, when the first motor is started, the first motor drives the rotating structure 401 to rotate 45 degrees each time, so that when one set of constant temperature flow channel components 3 finishes extracting explosive slurry, the flow channel docking port 301 of the next set of constant temperature flow channel components 3 can be aligned with the explosive stirring component 1. The second motor drives the four wheel axles 406 to rotate, thereby driving the four power wheels 407 to roll.

[0047] A retractable push rod is installed inside each of the eight slide grooves 402, one end of the retractable push rod is fixed inside the slide groove 402, and the other end of the retractable push rod is connected to the bottom of the limit structure 403. The eight retractable push rods are electrically connected to the remote data processor 504. When the remote data processor 504 controls the eight retractable push rods to start, the eight retractable push rods simultaneously drive the eight limit structures 403 to slide in the eight slide grooves 402. When the eight retractable push rods are extended, the eight limit structures 403 move away from the center of the circle, so that the flow channel interface 301 of one group of the constant temperature flow channel components 3 is connected to the passive valve 105; when the eight retractable push rods are retracted, the eight limit structures 403 move close to the center of the circle, so that the flow channel interface 301 of one group of the constant temperature flow channel components 3 is separated from the passive valve 105.

[0048] It should be noted that the rotation angle of the rotating structure 401 driven by the first motor is adjusted according to the number of constant temperature flow channel components 3. Since the number of constant temperature flow channel components 3 in the present invention is eight groups, the first motor only needs to drive the rotating structure 401 to rotate 45° each time.

[0049] Optionally, the visual recognition detection component 5 also includes: a visual recognition probe 501, a signal transmission line 502, a detector bracket 503 and a remote control structure 505.

[0050] Specifically, in the present invention, a glass protective cover is detachably installed on the outer periphery of the visual recognition probe 501.

[0051] In a specific implementation manner, the installation angle of the visual recognition probe 501 on the detector bracket 503 is adjustable. In the present invention, the angle of the visual recognition probe 501 should be located at the position where the explosive stirring assembly 1 extracts the explosive slurry. After one set of constant temperature flow channel assemblies 3 finishes extracting the explosive slurry, the visual recognition probe 501 can take a picture of it, so as to observe the state of the explosive slurry at this time and facilitate the staff to conduct real-time analysis of its dynamic viscosity without affecting the next extraction process of the explosive slurry.

[0052] After the visual recognition probe 501 finishes shooting, one group of constant temperature flow channel components 3 with explosive slurry inside is rotated 45° so that the next group of constant temperature flow channel components 3 is aligned with the visual recognition probe 501.

[0053] After the visual recognition probe 501 takes a picture of the extracted explosive slurry, the picture taken is transmitted to the remote data processor 504 through the signal transmission line 502. After the remote data processor 504 analyzes the picture and calculates the data to obtain the test result, the picture taken and the test result are displayed on the panel of the remote control structure 505. The staff can judge whether the dynamic viscosity data of the explosive slurry meets the requirements by observing the picture taken and the test result of the remote data processor 504.

[0054] Optionally, the explosive stirring assembly 1 includes: an explosive stirring kettle 101, a slurry extraction structure 102, an active valve 103, a density sensor 104 and a passive valve 105. The explosive stirring kettle 101 is fixed on the base support assembly 6. A stirring paddle 1011 is installed inside the explosive stirring kettle 101. The output shaft of the stirring paddle 1011 is connected to the base support assembly 6. The active valve 103 is fixed on one side of the explosive stirring kettle 101 and communicates with the inside of the explosive stirring kettle 101. One end of the slurry extraction structure 102 is connected to the active valve 103, and the other end of the slurry extraction structure 102 is connected to the passive valve 105. The passive valve 105 can be plugged into the flow channel docking interface 301 of one group of the constant temperature flow channel assemblies 3.
