Description

Technical Field

[0001] This utility model relates to the field of explosives production technology, specifically to an explosives water-oil phase mixing device. Background Technology

[0002] In the field of explosives production, the water-oil phase ratio mixing is a key step in the explosives preparation process, and its mixing effect and ratio accuracy directly affect the performance and quality of the explosives.

[0003] Regarding proportioning control, existing devices struggle to achieve precise water-oil ratios. Due to a lack of effective flow monitoring and regulation, the delivery rates of water and oil are often difficult to control precisely, resulting in substandard water-oil ratios in the mixed explosives. This negatively impacts key indicators such as explosive performance and stability. This not only increases the defect rate during explosive production but also poses a potential threat to the safety of subsequent explosive use. Furthermore, existing devices rely on simplistic stirring methods, typically using only a simple agitator, which fails to ensure thorough and uniform mixing of water and oil. Water and oil, as two liquids with different properties, exhibit differences in density, viscosity, and other physical properties. Simple stirring methods cannot effectively break down the interfacial tension between them, leading to uneven mixing and localized water-oil stratification or agglomeration. Therefore, this paper proposes an explosive water-oil phase proportioning and mixing device to address these issues. Utility Model Content

[0022] 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.

[0023] Please see Figures 1 to 3 The explosive water-oil phase mixing device in this embodiment includes a mixing box 1 and a transfer box 2. The top of the mixing box 1 is provided with a mixing component for water-oil mixing.

[0024] Please see Figure 1In this embodiment, the mixing component includes a motor 3 fixedly connected to the top of the mixing box 1. The output shaft of the motor 3 is fixedly connected to a transmission rod 4. A first stirring blade 5 is fixedly connected to the outer side of the transmission rod 4. A transmission gear 6 is fixedly connected to the bottom end of the transmission rod 4. Driven gears 7 mesh on both the left and right sides of the transmission gear 6. A driven rod 8 is fixedly connected to the inner side of the center of the driven gear 7. A second stirring blade 9 is fixedly connected to the outer side of the driven rod 8.

[0025] The left side of the mixing chamber 1 is provided with an enhancement component for enhancing the mixing effect. The enhancement component includes a support plate 10 fixedly connected to the left side of the mixing chamber 1. An ultrasonic generator 11 is fixedly connected to the top of the support plate 10. An ultrasonic transducer 12 is electrically connected to the electrical signal output terminal of the ultrasonic generator 11. An amplitude transformer 13 is fixedly connected to the vibration output terminal of the ultrasonic transducer 12. A transmitter head 14 is fixedly connected to the other end of the amplitude transformer 13.

[0026] Specifically, the surface of the transmitter head 14 is plated with a chromium plating, and the right side of the transmitter head 14 penetrates the left side wall of the mixing chamber 1 and extends into the interior of the mixing chamber 1.

[0027] It should be noted that the surface of the transmitter head 14 is plated with a chromium plating layer. The chromium plating layer has good wear resistance, corrosion resistance and high hardness. During long-term use, it can effectively resist the wear and corrosion of the transmitter head 14 by the explosive-water-oil mixture in the mixing box 1, extend the service life of the transmitter head 14 and ensure the stability and effectiveness of ultrasonic transmission.

[0028] Specifically, a partition 15 is fixedly connected to the inside of the transfer box 2. The space to the left of the partition 15 is a water chamber, and the space to the right of the partition 15 is an oil chamber.

[0029] It should be noted that this design allows water and oil to be stored independently in the transfer box 2, avoiding mixing between them. This facilitates subsequent mixing in the mixing box 1 according to the set ratio, ensuring the accuracy and stability of the ratio.

[0030] Specifically, the top left and right sides of the transfer box 2 are fixedly connected to conveying pipes 16. The left conveying pipe 16 is connected to the water chamber, and the right conveying pipe 16 is connected to the oil chamber.

[0031] It should be noted that water and oil can be transported from the outside to the water chamber and oil chamber of the transfer box 2 through these two conveying pipes 16, respectively, to provide raw materials for subsequent proportioning and mixing. The independent conveying pipes 16 design facilitates separate control of the conveying of water and oil.

[0032] Specifically, connecting valves 17 are fixedly connected to the left and right sides of the bottom of the transfer box 2. Connecting pipes 18 are fixedly connected to the bottom of the connecting valves 17. Flow meters 19 are fixedly connected to the bottom of the connecting pipes 18. Flow meters 19 are fixedly connected to the top of the mixing box 1.

[0033] It should be noted that the connecting valve 17 is used to control the delivery of water and oil from the water chamber and oil chamber to the mixing tank 1, the connecting pipe 18 serves as a delivery channel, and the flow meter 19 can accurately measure the flow rate of water and oil delivered from the connecting pipe 18 to the mixing tank 1, thereby achieving precise control of the water and oil ratio.

[0034] Specifically, a fixing rod 20 is fixedly connected to the inner bottom wall of the mixing box 1, and a protective shell 21 is fixedly connected to the top of the fixing rod 20. The transmission gear 6 and the driven gear 7 are both bevel gears, and both the transmission gear 6 and the driven gear 7 are located inside the protective shell 21.

[0035] It should be noted that the protective shell 21 protects the transmission gear 6 and the driven gear 7, preventing the explosive-water-oil mixture in the mixing box 1 from entering the gear meshing part.

[0036] Specifically, the left end of the left driven rod 8 passes through the inner left side wall of the protective shell 21 and is rotatably connected to the inner left side wall of the mixing box 1, and the right end of the right driven rod 8 passes through the inner right side wall of the protective shell 21 and is rotatably connected to the inner right side wall of the mixing box 1.

[0037] In addition, discharge valves are fixedly connected to both the left and right sides of the bottom of the mixing tank 1 for discharging the water-oil mixture.

[0038] The working principle of the above embodiments is as follows:

[0039] Water and oil are transported into the transfer box 2 through the conveying pipe 16 on the left and the conveying pipe 16 on the right at the top of the transfer box 2, respectively. The left conveying pipe 16 transports water to the water chamber on the left side of the partition 15, and the right conveying pipe 16 transports oil to the oil chamber on the right side of the partition 15, thus completing the independent storage of water and oil and preparing for subsequent mixing.

[0040] According to the set explosive water-oil ratio, the connecting valves 17 on the left and right sides of the bottom of the transfer box 2 are opened respectively. Water enters the left connecting pipe 18 from the water chamber through the left connecting valve 17, and oil enters the right connecting pipe 18 from the oil chamber through the right connecting valve 17. When water and oil flow in the connecting pipe 18, the flow rate of water and oil is measured in real time by the flow meter 19. Then, the opening of the connecting valve 17 is adjusted according to the flow data to control the flow rate of water and oil, so that water and oil enter the mixing box 1 through the flow meter 19 according to the set ratio.

[0041] After water and oil enter the mixing tank 1, the motor 3 fixedly connected to the top of the mixing tank 1 is started. The output shaft of the motor 3 drives the transmission rod 4 to rotate, and the first stirring blade 5 fixedly connected to the outside of the transmission rod 4 rotates accordingly, performing preliminary stirring and mixing of water and oil in the mixing tank 1. At the same time, the transmission rod 4 drives the driven gear 7 meshing with it to rotate through the transmission gear 6. The driven gear 7 then drives the driven rod 8 and the second stirring blade 9 to further stir and mix water and oil.

[0042] Furthermore, the ultrasonic generator 11 is activated, generating an electrical signal and outputting it to the ultrasonic transducer 12. The ultrasonic transducer 12 converts the electrical signal into mechanical vibration, which is amplified by the amplitude transformer 13 and transmitted to the transmitter head 14. The transmitter head 14 transmits the ultrasonic vibration to the explosive-water-oil mixture in the mixing box 1. By utilizing the cavitation effect of the ultrasonic waves, the mixing effect of water and oil is further enhanced, making the water and oil mix more evenly.

[0043] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
