Description

Technical Field

[0001] The utility model relates to the technical field of emulsion explosive production, in particular to an integrated liquid oil phase heat preservation and heating system for emulsion explosives. Background Art

[0002] Emulsion explosives use an aqueous oxidizer solution as the water phase and a composite wax and emulsifier as the oil phase. A special water-in-oil emulsion is formed by agitating a rotor at a specific speed. Microbubbles are introduced as sensitizers to create an explosive mixture. The oil phase, as the external phase, primarily determines the physical and appearance properties of the emulsion explosive. The emulsifier, acting as a surfactant, plays a decisive role in the stability of the emulsion, making the oil phase crucial to the quality of the emulsion explosive. Existing emulsion explosive production lines primarily use two methods for preparing the oil phase: one uses a solid-state, integrated oil phase, where the supplier provides the product in boxes or bags, which workers manually place in a wax melting tank to melt for later use. The other involves suppliers directly delivering the liquid raw materials, emulsifier and composite wax, to storage tanks in the production area via tank trucks. Preparation tanks then weigh and meter the emulsifier and composite wax, mixing them into the emulsion explosive oil phase according to the desired proportions.

[0003] However, the two existing oil phase preparation technologies have the following problems: for the first method, due to the use of steam heating, the emulsifier in the oil phase material is easily affected by high temperature and degraded, thereby affecting product quality. In addition, this process still requires manual operation, which is not in line with the development trend of industry automation. The second method requires the use of preparation tanks in the production area to measure and stir the emulsifier and compound wax. During the metering process, the residual material in the pipe after the pump is stopped and the accuracy of the sensor can easily make it difficult to control the accuracy of the ratio, thereby affecting product quality.

[0004] Therefore, it is necessary to invent an integrated liquid oil phase heat preservation and heating system for emulsion explosive to solve the above problems. Utility Model Content

[0005] In order to solve the problems existing in the existing oil phase preparation technology, such as the high-temperature degradation of the emulsifier and the inconvenience of manual operation caused by steam heating of the solid-state integrated oil phase provided by the supplier, and the difficulty in controlling the ratio accuracy caused by the self-preparation of the oil phase in the production area, the utility model provides an insulation and heating system for the integrated liquid oil phase of emulsion explosives.

[0006] The utility model is realized by adopting the following technical solutions:

The controller is electrically connected to the feed pump I, the feed valve I, the feed pump II, and the feed valve II, respectively;

[0009] The hot water storage tank is provided with a water inlet I, a water outlet I, a water outlet II, and a return water port I.

The controller is electrically connected to the water supply pump I, the water supply valve I, and the return water pump I, respectively;

[0010] A coil is installed inside the integrated liquid oil phase storage tank, and the water inlet of the coil is connected to the water outlet II of the hot water storage tank through the water supply pipe II. A water supply pump II and a water supply valve II are installed on the water supply pipe II, and the water supply valve II is located between the hot water storage tank and the water supply pump II. The water outlet of the coil is connected to the return water outlet I of the hot water storage tank through the return pipe II, and a return pump II is installed on the return pipe II.

[0011] Furthermore, a filter is installed on the feed pipe I, and the filter is located between the feed pump I and the feed valve I.

[0012] Furthermore, a heating wire is installed on the hot water storage tank, and the heating wire is electrically connected to the controller.

[0013] Furthermore, an agitator is installed inside the integrated liquid oil phase storage tank, and the agitator is electrically connected to the controller.

At the same time, the integrated liquid oil phase storage tank and the hot water storage tank are used to achieve the insulation function, ensuring the fluidity and uniformity of the integrated liquid oil phase and ensuring product quality. The system's integrated automatic control not only reduces the need for manual operation and improves safety, but also improves the continuity and stability of production. In addition, since the liquid composite wax and the liquid emulsifier are measured and mixed in advance at the supplier to form an integrated liquid oil phase, and then transported to the integrated liquid oil phase storage tank in the production area by a tank truck for unloading, the utility model only needs to use hot water to insulate or heat the integrated liquid oil phase in the integrated liquid oil phase storage tank, and can be used normally afterwards, avoiding the existing problem of difficult accuracy control in the production area of ​​using preparation tanks to weigh and measure and prepare the emulsifier and composite wax into the emulsion explosive oil phase in proportion, thereby ensuring the quality of the oil phase and the stable production of the emulsion explosive.

[0023] The discharge port of the tank truck 1 is connected to the feed port of the integrated liquid oil phase storage tank 3 through a feed pipe I6, and a feed pump I7 and a feed valve I8 are installed on the feed pipe I6, and the feed pump I7 is located between the feed valve I8 and the integrated liquid oil phase storage tank 3. The discharge port of the integrated liquid oil phase storage tank 3 is connected to the feed port of the emulsifier 2 through a feed pipe II9, and a feed pump II10 and a feed valve II11 are installed on the feed pipe II9, and the feed pump II10 is located between the feed valve II11 and the emulsifier 2. The controller is electrically connected to the feed pump I7, the feed valve I8, the feed pump II10, and the feed valve II11 respectively;

[0024] The hot water storage tank 5 is provided with a water inlet I, a water outlet I, a water outlet II, and a return water port I. The water inlet I of the hot water storage tank 5 is connected to the water outlet of the air source heat pump water heater 4 through a water supply pipe I 12. A water supply pump I 13 and a water supply valve I 14 are installed on the water supply pipe I 12, and the water supply valve I 14 is located between the air source heat pump water heater 4 and the water supply pump I 13. The water outlet I of the hot water storage tank 5 is connected to the return water port of the air source heat pump water heater 4 through a return water pipe I 15. A return water pump I 16 is installed on the return water pipe I 15. The controller is electrically connected to the water supply pump I 13, the water supply valve I 14, and the return water pump I 16 respectively;

[0025] A coil is installed inside the integrated liquid oil phase storage tank 3, and the water inlet of the coil is connected to the water outlet II of the hot water storage tank 5 through the water supply pipe II. A water supply pump II and a water supply valve II are installed on the water supply pipe II, and the water supply valve II is located between the hot water storage tank 5 and the water supply pump II. The water outlet of the coil is connected to the return water outlet I of the hot water storage tank 5 through the return water pipe II, and a return water pump II is installed on the return water pipe II.

[0026] In the present invention, the combined structural design of the air source heat pump water heater 4, the hot water storage tank 5, the water supply pipe I12, the water supply pump I13, the water supply valve I14, the return pipe I15, and the return pump I16 realizes the water supply heating cycle. The air source heat pump water heater 4 absorbs heat from the environment to heat cold water into hot water, and stores it in the hot water storage tank 5. The circulation loop ensures that the water temperature in the hot water storage tank 5 is stable, providing a constant heat source for other links. Compared with the traditional steam heating method, the air source heat pump water heater 4 provides a more gentle heating and heat preservation method, avoiding high temperature in subsequent links. The degradation of emulsifier is improved, thereby improving product quality; the combined structural design of hot water storage tank 5, water supply pipe II, water supply pump II, water supply valve II, coil, return pipe II, and return pump II realizes the heating cycle. The hot water in hot water storage tank 5 is transported to the coil inside integrated liquid oil phase storage tank 3 through water supply pipe II, indirectly and evenly heating the oil phase, and the used hot water is returned to hot water storage tank 5 through return pipe II, forming a cycle, ensuring uniform temperature distribution in integrated liquid oil phase storage tank 3, avoiding local overheating and causing degradation of emulsifier; tank truck 1, emulsifier 2, integrated liquid The combined structural design of the oil phase storage tank 3, coil, controller, feed pipe I6, feed pump I7, feed valve I8, feed pipe II9, feed pump II10, feed valve II11 and controller realizes that the integrated liquid oil phase can be input into the integrated liquid oil phase storage tank 3 for storage and standby after being unloaded from the tank truck 1, and is heated by the coil in the integrated liquid oil phase storage tank 3 and then input into the emulsifier 2 for the next process. Since the liquid composite wax and the liquid emulsifier are measured and mixed in advance at the supplier to form an integrated liquid oil phase, and then transported to the integrated liquid phase of the production area by the tank truck 1, the integrated liquid phase can be stored in the integrated liquid phase storage tank 3. The unloading is carried out at the liquid oil phase storage tank 3, so the utility model only needs to use hot water to keep the integrated liquid oil phase in the integrated liquid oil phase storage tank 3 warm or heat it, and then it can be used normally. This avoids the problem of difficult control of accuracy caused by the existing method of weighing and measuring in the production area using the preparation tank and preparing the emulsifier and compound wax into the emulsion explosive oil phase in proportion, thereby ensuring the quality of the oil phase and the stable production of the emulsion explosive. At the same time, the controller realizes the automatic control of the water heating cycle, the heat supply cycle and the feeding process, reduces the need for manual operation and improves the operation safety.

[0027] A filter 17 is installed on the feed pipe I6, and the filter 17 is located between the feed pump I7 and the feed valve I8.

[0028] The filter 17 is used to filter the integrated liquid oil phase before entering the integrated liquid oil phase storage tank 3 to prevent impurities from entering the system and ensure the quality of the oil phase.

[0029] The hot water storage tank 5 is provided with a heating wire 18 , which is electrically connected to the controller.

[0030] The heating wire 18 is used to assist in heating the water in the hot water storage tank 5, ensuring the stability of the hot water supply and further ensuring the heating effect of the integrated liquid oil phase.

[0031] An agitator 19 is installed inside the integrated liquid oil phase storage tank 3 , and the agitator 19 is electrically connected to the controller.

[0032] The agitator 19 is used to keep the integrated liquid oil phase uniform, prevent the occurrence of stratification, and ensure the consistency of the oil phase.

[0033] The hot water storage tank 5 is provided with a water inlet II, the water inlet II is connected to a water supply pipe 20 , and a water supply pump 21 and a water supply valve 22 are installed on the water supply pipe 20 .

[0034] The combined structure of the water supply pipe 20, the water supply pump 21 and the water supply valve 22 is designed to supply cold water to the hot water storage tank 5, maintain the water balance in the hot water storage tank 5, and ensure a continuous supply of hot water.

[0035] The hot water storage tank 5 is provided with a water inlet III, the water inlet III is connected to a waste heat recovery pipe 23 , and a waste heat recovery water supply pump 24 and a waste heat recovery water supply valve 25 are installed on the waste heat recovery pipe 23 .

[0036] The combined structural design of the waste heat recovery pipe 23, the waste heat recovery water supply pump 24, and the waste heat recovery water supply valve 25 can be connected to the tail steam of the existing ammonium nitrate aqueous solution storage tank heating system, and the collected tail steam waste heat can be used to assist in heating the water in the hot water storage tank 5, saving energy.

[0037] A liquid level switch 26 is provided inside the hot water storage tank 5 , and the liquid level switch 26 is electrically connected to the controller.

[0038] The liquid level switch 26 can continuously detect the water level in the hot water storage tank 5 to prevent water shortage or overflow and ensure the normal operation of the system.

[0039] A liquid level gauge 27 is installed inside the integrated liquid oil phase storage tank 3 , and the liquid level gauge 27 is electrically connected to the controller.

[0040] The liquid level meter 27 can monitor the liquid level in the integrated liquid oil phase storage tank 3 to ensure visual management of the oil phase reserves and facilitate timely replenishment of the oil phase.

[0041] The hot water storage tank 5 is provided with a water outlet III and a return water port II. The feed pipe II9 is ​​provided with a hot water insulation layer, which is connected to the water outlet III of the hot water storage tank 5 through the water supply pipe III28. A water supply pump III29 and a water supply valve III30 are installed on the water supply pipe III28. The hot water insulation layer is connected to the return water port II of the hot water storage tank 5 through the return water pipe III31, and a return water pump III32 is installed on the return water pipe III31.

[0042] The combined structural design of the hot water insulation layer, water supply pipe III 28, water supply pump III 29, water supply valve III 30, return pipe III 31, return pump III 32, and hot water storage tank 5 provides a heat preservation function for the feed pipe II 9, preventing the oil phase from cooling during transportation, ensuring its fluidity, and reducing energy loss.

[0043] During operation, the integrated liquid oil phase prepared in advance is first transported from the supplier to the integrated liquid oil phase storage tank 3 in the production area by the tank truck 1, and the discharge port of the tank truck 1 is connected to the feed port of the integrated liquid oil phase storage tank 3 through the feed pipe Ⅰ6. The controller controls to open the feed valve Ⅰ8, and the integrated liquid oil phase is pumped into the integrated liquid oil phase storage tank 3 through the feed pipe Ⅰ6. The staff starts the agitator 19 through the controller to keep the integrated liquid oil phase uniform, and at the same time starts the air source heat pump water heater 4 to heat water. The temperature of the air source heat pump water heater 4 is set to 70℃ in advance. When the temperature is reached, the staff controls to open the water supply valve Ⅰ14 through the controller, and starts the water supply pump Ⅰ13, so that the hot water is transported to the hot water storage tank 5 through the water supply pipe Ⅰ12, and the hot water is stored in the hot water storage tank 5. The return water pump Ⅰ16 is started to make the hot water in the hot water storage tank 5 be transported through the return water pipe Ⅰ15 It is sent to the air source heat pump water heater 4 for circulating heating. When the hot water temperature is constant at 70°C, the controller opens the water supply valve II and starts the water supply pump II, so that the hot water in the hot water storage tank 5 enters the coil inside the integrated liquid oil phase storage tank 3 through the water supply pipe II. The controller starts the return pump II, and the hot water flowing through the coil heats the integrated liquid oil phase in the integrated liquid oil phase storage tank 3 and then flows back to the hot water storage tank 5 through the return pipe II; when the integrated liquid oil phase needs to be sent to the emulsifier 2, the controller starts the feed pump II 10, opens the feed valve II 11, and the integrated liquid oil phase is transported to the emulsifier 2 through the feed pipe II 9, thereby completing the use of this system; it overcomes the problems of the existing oil phase preparation technology that the solid integrated oil phase provided by the supplier is heated by steam, resulting in high-temperature degradation of the emulsifier and inconvenience in manual operation, and the difficulty in controlling the ratio accuracy due to the self-preparation of the oil phase in the production area.

[0044] During the water heating cycle, the liquid level switch 26 continuously monitors the water level in the hot water storage tank 5. When the water level is too high, the controller controls the closure of the water supply valve I14 and stops the water supply pump I13; when the water level is too low, the water supply pipe 20 is connected to the hot water storage tank 5 and the external water source, the controller controls the opening of the water supply valve 22, and starts the water supply pump 21 to transport the external water source to the hot water storage tank 5.

[0045] During the heating cycle, the liquid level meter 27 continuously monitors the liquid level in the integrated liquid oil phase storage tank 3. When the liquid level is too high, the controller controls the closure of the feed valve I8 and stops the feed pump I7; when the liquid level is too low, the controller controls the closure of the feed valve II11 and stops the feed pump II10.

[0046] During the specific implementation process, it is necessary to prepare the integrated liquid oil phase in advance. The preparation process requires the raw material supplier to evenly mix the composite wax and emulsifier in proportion to form a liquid integrated oil phase, ensuring the accurate ratio of the composite wax and the emulsifier. Then the tank truck 1 transports the integrated liquid oil phase from the supplier to the integrated liquid oil phase storage tank 3 in the production area, eliminating the oil phase supplier's mold separation, cooling, packaging and other processes, as well as the manual steps of loading and unloading, saving a lot of costs and energy consumption. Since the integrated liquid oil phase transported to the production area has a certain temperature, it only needs to be kept warm at 60℃-75℃, which not only maintains a certain fluidity of the oil phase, but also will not destroy the emulsifier molecules, ensuring the quality of the oil phase, and at the same time does not require a special warehouse to store the oil phase.
