Description

Technical Field

[0001] The present invention relates to the technical field of chemical solution transportation, and particularly relates to an ammonium nitrate solution transportation device for the production of expanded ammonium nitrate explosives. Background Art

[0002] Ammonium nitrate itself is a white crystalline solid under normal temperature and pressure. However, when ammonium nitrate dissolves in water, an ammonium nitrate solution is formed. In the solution system, ammonium nitrate, as a solute, is uniformly dispersed in the solvent water, presenting the form and properties of a liquid, with liquid characteristics such as fluidity. Ammonium nitrate is a key raw material in the manufacture of industrial explosives, and ammonium nitrate fuel oil explosives made by mixing with fuel oil are widely used in fields such as mining and construction blasting.

[0003] The temperature of the ammonium nitrate solution varies in different usage scenarios. Generally, when the ammonium nitrate solution is stored and transported, the temperature of the ammonium nitrate solution should be controlled at a relatively low level. When the ammonium nitrate solution is used for industrial synthesis, the ammonium nitrate solution needs to be heated to raise the temperature of the ammonium nitrate solution to a suitable temperature to meet the requirements of the synthesis process. After the temperature of the ammonium nitrate solution rises, there are certain safety hazards, and it is necessary to flexibly control the temperature of the ammonium nitrate solution. While ensuring that the temperature of the ammonium nitrate solution meets the production requirements of ammonium nitrate explosives, the safety is improved. Therefore, the present application provides an ammonium nitrate solution transportation device for the production of expanded ammonium nitrate explosives and its detection method to meet the requirements.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by setting up a lifting component, through the telescopic cooperation of the electric telescopic rod, the suction pipe and the output pipe, the initial transfer of the ammonium nitrate solution in the ammonium nitrate solution barrel is realized through the output pipe. At the same time, through the special design of the suction pipe and the anti-leakage ring, when the suction pipe enters the ammonium nitrate solution barrel to suck the ammonium nitrate solution, the anti-leakage ring prevents the ammonium nitrate solution in the ammonium nitrate solution barrel from spilling, improving the safety during the transfer and transportation of the ammonium nitrate solution. At the same time, through the special design of the diversion groove on the bottom surface of the suction pipe, using the hot water generated in the heat preservation component, after the ammonium nitrate solution transportation work is completed, the surface of the suction pipe is cleaned. At the same time, the residual ammonium nitrate solution on the surface of the output pipe is scraped off through the diversion ring, avoiding the corrosion of the equipment caused by the residual ammonium nitrate solution on the surfaces of the suction pipe and the output pipe, and improving the service life of the suction pipe and the output pipe.

[0018] By setting up a heat preservation component, through setting up a heating barrel and a water storage barrel, the replenishment of the water and liquid between the heating barrel and the water storage barrel is realized. The heating rod is used to heat the water and liquid in the heating barrel. At the same time, the hot water and water vapor generated after heating the water and liquid in the heating barrel are differentiated and utilized. Through the connection effect of the exhaust pipe and the sleeve, the water vapor is introduced into the sleeve to realize the heating and heat preservation effect of the conveying pipe in the sleeve by using the water vapor. At the same time, the heat preservation pipe is used to divert the hot water in the heating barrel to heat and keep warm the heat preservation barrel. Thus, during the transportation and waiting for transportation of the ammonium nitrate solution, the ammonium nitrate solution is heated and kept warm in stages, so that the temperature of the ammonium nitrate solution meets the synthesis and processing requirements. At the same time, through the suction cooperation of the first water pump and the spray pipe, after the ammonium nitrate solution transportation work is completed, the hot water in the heat preservation pipe is reused to clean the residual ammonium nitrate solution on the surface of the suction pipe, improving the service life of the suction pipe and reducing the maintenance cost. At the same time, when the temperature of the ammonium nitrate solution is relatively high, through the cooling effect of the cooling component, the exhaust pipe is used to guide the cooled water after spraying to flow back, and at the same time, the heat preservation pipe is used to cool down the heat preservation barrel, realizing the switching between the heating and cooling effects of the heat preservation barrel and the heat preservation pipe. At the same time, the passages between the heating barrel, the heat preservation pipe, the heat preservation barrel and the exhaust pipe simultaneously have two effects of heating and heat preservation and cooling and temperature reduction, realizing the dual effects of a single passage, improving the applicability of the sodium nitrate solution transportation, and reducing the use cost.

[0019] By setting up a shock-absorbing component, through the cooperation of a bottom plate, a mounting frame, multiple groups of support plates and springs, and the elastic connection effect of the springs among the support plates, the bottom plate and the mounting frame, shock absorption treatment is respectively carried out on the magnetic pump, the casing and the conveying pipe, so as to avoid the vibration generated during the operation of the magnetic pump from affecting the ammonium nitrate solution, further ensure the conveying effect of the ammonium nitrate solution, avoid loosening between the magnetic pump and the casing, thereby avoiding the corrosion of the equipment caused by the leakage of the ammonium nitrate solution, improve the overall service life of the equipment. At the same time, the magnetic pump is secondarily protected by a protective shell, and a gas detector is used to detect the gas inside the protective shell. When the temperature of the ammonium nitrate solution is too high, nitrous oxide and other gases generated by the ammonium nitrate solution are monitored in real time, reducing the safety hazards during the conveying of the ammonium nitrate solution and further ensuring the safety during the conveying of the ammonium nitrate solution.

[0020] By setting up a cooling component, through the connection effect between the second water pump and the water storage bucket, when the temperature of the ammonium nitrate solution is relatively high, through the switching effect between two groups of solenoid valves and the water inlet pipe, the cold water stored in the water storage bucket is pumped and utilized. Through the shunt pipe and multiple spray pipes installed at the bottom end of one of the water inlet pipes, the surface of the conveying pipe is sprayed and cooled, avoiding the relatively high temperature of the ammonium nitrate solution conveyed in the conveying pipe, reducing the accident probability after the temperature of the ammonium nitrate solution is too high. At the same time, by using the other group of solenoid valves and the water inlet pipe, the cold water is introduced into the conveying pipe to dilute the ammonium nitrate solution, reducing the oxidizing property and potential danger of the ammonium nitrate solution. At the same time, in cooperation with the spray cooling effect of the spray pipes on the surface of the conveying pipe, temperature reduction and dilution treatment are realized in terms of both the temperature and concentration of the ammonium nitrate solution, further avoiding the danger brought by the too high temperature of the ammonium nitrate solution.

[0044] As Figures 1 to 14 shown, an embodiment of the present invention provides a device for transporting ammonium nitrate solution for the production of expanded ammonium nitrate explosives, including a mounting housing 1, a control module 2 is installed on one end surface of the mounting housing 1, a sealing door 20 is installed on one side of the mounting housing 1, a placement table 21 is installed on one side of the inner wall of the mounting housing 1, a water storage bucket 3 is installed on one side of the inner wall of the mounting housing 1, a first water inlet pipe 4 is installed through one side of the bottom end of the water storage bucket 3, a magnetic pump 5 is installed at the top end of the inner wall of the mounting housing 1, a sleeve 6 is nested and installed on one side of the mounting housing 1, a conveying pipe 7 is nested and installed inside the sleeve 6, the material of the conveying pipe 7 is set as stainless steel material, one end of the conveying pipe 7 is connected to the magnetic pump 5, a lifting assembly 8, a lifting assembly 8 is installed on one side of the inner wall of the mounting housing 1, the lifting assembly 8 is used to transfer the ammonium nitrate solution in the ammonium nitrate solution bucket to the heat preservation assembly 9, a heat preservation assembly 9, a heat preservation assembly 9 is installed on the inner wall of the mounting housing 1, the heat preservation assembly 9 is used to perform heat preservation treatment on the ammonium nitrate solution, a shock absorption assembly 10, a shock absorption assembly 10 is installed at the top of the inner wall of the mounting housing 1, the shock absorption assembly 10 is used to perform shock absorption treatment on the magnetic pump 5 and the sleeve 6, a cooling assembly 11, a cooling assembly 11 is installed through one side of the water storage bucket 3, the cooling assembly 11 is used to perform cooling treatment on the ammonium nitrate solution, the heat preservation assembly 9 is located on one side of the lifting assembly 8, the shock absorption assembly 10 is located on the top of the heat preservation assembly 9, and the cooling assembly 11 is located on one side of the heat preservation assembly 9.

[0045] By setting the lifting assembly 8, the initial transfer of the ammonium nitrate solution in the ammonium nitrate solution bucket is realized through the output pipe 87. At the same time, through the specially designed suction pipe 84 and anti-leakage ring 85, the ammonium nitrate solution in the ammonium nitrate solution bucket is prevented from spilling. By setting the heat preservation assembly 9, the heat preservation bucket 97 is heated and insulated, so as to realize the hierarchical heating and insulation of the ammonium nitrate solution during the transportation and waiting for transportation of the ammonium nitrate solution, so that the temperature of the ammonium nitrate solution meets the requirements of synthesis and processing. By setting the shock absorption assembly 10, the vibration generated during the operation of the magnetic pump 5 is avoided from affecting the ammonium nitrate solution, further ensuring the transportation effect of the ammonium nitrate solution, avoiding loosening between the magnetic pump 5 and the sleeve 6, thereby avoiding the corrosion of the equipment caused by the leakage of the ammonium nitrate solution, and improving the overall service life of the equipment. By setting the cooling assembly 11, the cooling and dilution treatment of the ammonium nitrate solution in terms of temperature and concentration are realized, further avoiding the danger caused by too high temperature of the ammonium nitrate solution.

[0046] As Figures 3 to 5 shown, the lifting assembly 8 includes an electric telescopic rod 81. The electric telescopic rod 81 is installed at the bottom end of the inner wall of the installation housing 1. An installation plate 82 is installed at the top end of the electric telescopic rod 81. A centrifugal pump 83 is installed at the top end of the installation plate 82. One end of the centrifugal pump 83 is connected to a suction pipe 84. A leak-proof ring 85 is installed on the surface of the suction pipe 84. A diversion groove 86 is installed on the bottom surface of the suction pipe 84. The materials of the suction pipe 84 and the diversion groove 86 are both set to stainless steel. The other end of the centrifugal pump 83 is installed with an output pipe 87. A diversion ring 88 is in contact with the outer surface of the output pipe 87. The diversion ring 88 is installed on the inner wall of the heat preservation barrel 97. The materials of the output pipe 87 and the diversion ring 88 are both set to stainless steel.

[0047] The operator first opens the sealing door 20 and places the ammonium nitrate solution barrel on the placing table 21. Subsequently, the control module 2 controls the electric telescopic rod 81 to start. After the electric telescopic rod 81 starts, it contracts and drives the installation plate 82 to slide downward. While the installation plate 82 slides, it synchronously drives the suction pipe 84 and the output pipe 87 to slide downward simultaneously, and makes the suction pipe 84 enter the ammonium nitrate solution barrel and block the top opening of the ammonium nitrate solution barrel through the leak-proof ring 85 to avoid splashing of the ammonium nitrate solution, and at the same time makes the output pipe 87 enter the heat preservation barrel 97;

[0048] Subsequently, the control module 2 controls the centrifugal pump 83 to start. After the centrifugal pump 83 starts, it sucks out the ammonium nitrate solution in the ammonium nitrate solution barrel through the suction pipe 84 and transfers it to the heat preservation barrel 97 through the output pipe 87 for preliminary transfer of the ammonium nitrate solution in the ammonium nitrate solution barrel;

[0049] When the ammonium nitrate solution conveying work is completed, the control module 2 controls the electric telescopic rod 81 to start again. After the electric telescopic rod 81 starts, it extends and resets to drive the installation plate 82 to slide upward. While the installation plate 82 slides, it synchronously drives the suction pipe 84 and the output pipe 87 to slide upward simultaneously, and makes the suction pipe 84 separate from the ammonium nitrate solution barrel, and at the same time makes the output pipe 87 separate from the heat preservation barrel 97. At the same time, the control module 2 controls the first water pump 99 to start. After the first water pump 99 starts, it pumps out the hot water in the heat preservation pipe 98 and sprays it out through the spray pipe 910;

[0050] After the hot water is sprayed out, it slides down along the surface of the suction pipe 84 under the action of the gravity factor and drips through the diversion groove 86. During this process, the surface of the suction pipe 84 is cleaned with the hot water to clean the ammonium nitrate solution stained on the surface of the suction pipe 84. At the same time, while the output pipe 87 slides, it passes through and contacts the diversion ring 88. Under the scraping action of the diversion ring 88, the ammonium nitrate solution stained on the surface of the output pipe 87 is scraped off, and through the guiding action of the diversion ring 88, under the action of the gravity factor, the scraped ammonium nitrate solution drips into the heat preservation barrel 97.

[0051] By setting the telescopic cooperation of the electric telescopic rod 81, the suction pipe 84 and the output pipe 87, the initial transfer of the ammonium nitrate solution in the ammonium nitrate solution barrel is realized through the output pipe 87. At the same time, through the special design of the suction pipe 84 and the anti-leakage ring 85, when the suction pipe 84 enters the ammonium nitrate solution barrel to suck the ammonium nitrate solution, the anti-leakage ring 85 prevents the ammonium nitrate solution in the ammonium nitrate solution barrel from spilling, improving the safety during the transfer and transportation of the ammonium nitrate solution. At the same time, through the special design of the diversion groove 86 on the bottom surface of the suction pipe 84, the hot water generated in the heat preservation component 9 is used to clean the surface of the suction pipe 84. At the same time, the residual ammonium nitrate solution on the surface of the output pipe 87 is scraped off by the diversion ring 88, improving the service life of the suction pipe 84 and the output pipe 87.

[0052] As Figures 7 to 8 shown, the heat preservation component 9 includes a heating barrel 90, the heating barrel 90 is installed on the inner wall of the installation shell 1, the top end of the heating barrel 90 is connected through a exhaust pipe 91, one end of the exhaust pipe 91 is connected through to the sleeve 6, one side of the heating barrel 90 is installed through a water supply pipe 92, one end of the water supply pipe 92 is connected with a valve 93, the valve 93 is installed at the bottom end of the water storage barrel 3, the bottom end of the heating barrel 90 is installed with a drain valve 94, the bottom end inner wall of the heating barrel 90 is nested and installed with a heating rod 95, one side inner wall of the heating barrel 90 is installed with a liquid level sensor 96, the heat preservation component 9 further includes a heat preservation barrel 97, the heat preservation barrel 97 is installed on the inner wall of the installation shell 1, a heat preservation pipe 98 is installed in the inner cavity of the heat preservation barrel 97, one end of the heat preservation pipe 98 extending out of the heat preservation barrel 97 is connected through to the heating barrel 90, the other end of the heat preservation pipe 98 extending out of the heat preservation barrel 97 is connected with a first water pump 99, the first water pump 99 is installed at the top end of the heat preservation barrel 97, and one end of the first water pump 99 is connected with a spray pipe 910.

[0053] After the ammonium nitrate solution is initially transferred to the heat preservation barrel 97, the control module 2 controls the magnetic pump 5 to start. The magnetic pump 5 transports the ammonium nitrate solution in the heat preservation barrel 97 into the transport pipe 7, and transports the ammonium nitrate solution to the expanded ammonium nitrate explosive production container through the transport pipe 7;

[0054] During this process, the control module 2 controls the heating rod 95 to start, heats the water stored in the heating barrel 90 through the heating rod 95, and causes the water in the heating barrel 90 to boil and generate steam. The steam in the heating barrel 90 enters the sleeve 6 through the exhaust pipe 91 at the top of the heating barrel 90, and accumulates in the cavity formed between the sleeve 6 and the conveying pipe 7. The conveying pipe 7 is continuously heated by the steam to heat and keep warm the ammonium nitrate solution passing through the conveying pipe 7. At the same time, the liquid level sensor 96 is used to detect the liquid level height of the water in the heating barrel 90 in real time, and the obtained data is transmitted to the control module 2 through an electric signal. When the water in the heating barrel 90 decreases, the control module 2 controls the valve 93 to open, and the water stored in the water storage barrel 3 is supplemented into the heating barrel 90 through the valve 93 and the water supply pipe 92, realizing the real-time supplement of the water and liquid in the heating barrel 90, ensuring the continuity of the heating effect of the heating barrel 90 on the conveying pipe 7, so that the temperature of the ammonium nitrate solution conveyed in the conveying pipe 7 meets the processing requirements;

[0055] While the heating rod 95 heats the water in the heating barrel 90, the heated water in the heating barrel 90 simultaneously enters the heat preservation pipe 98. Through the spiral structure of the heat preservation pipe 98, a heat preservation layer is formed in the inner cavity of the heat preservation pipe 98, and the ammonium nitrate solution in the heat preservation barrel 97 is heat-preserved by the water heated in the heat preservation pipe 98.

[0056] By setting the heating barrel 90 and the water storage barrel 3, the supplement of water and liquid between the heating barrel 90 and the water storage barrel 3 is realized. The heating rod 95 is used to heat the water and liquid in the heating barrel 90, and at the same time, the hot water and steam generated after heating the water and liquid in the heating barrel 90 are distinguished and utilized to perform hierarchical heating and heat preservation on the ammonium nitrate solution, so that the temperature of the ammonium nitrate solution meets the synthesis processing requirements.

The top ends of several of the multiple groups of support plates 102 are connected to the bottom end of the magnetic pump 5. A protective shell 104 is installed at the top of the magnetic pump 5, and a gas detector 105 is installed at the top of the protective shell 104. The shock absorption assembly 10 further includes a positioning ring 106, the positioning ring 106 is sleeved on the surface of the sleeve 6, and the remaining several groups of support plates 102 and springs 103 among the multiple groups of support plates 102 and springs 103 are arranged at equal angles on the surface of the positioning ring 106. One ends of the remaining multiple groups of support plates 102 among the multiple groups of support plates 102 are installed with an installation frame 107, the installation frame 107 is installed on the inner wall of the installation housing 1, and the positioning ring 106 is connected to the installation frame 107 through the remaining multiple groups of support plates 102. One ends of the remaining multiple groups of springs 103 among the multiple groups of springs 103 are elastically connected to the installation frame 107.

[0058] After the magnetic pump 5 is started, the magnetic pump 5 is supported through the connection effect between the bottom plate 101 and the support plate 102. At the same time, when the magnetic pump 5 is started and running, the magnetic pump 5 generates vibrations during operation. The vibrations generated during the operation of the magnetic pump 5 are shock-absorbed through the spring 103 elastically connected between the bottom plate 101 and the support plate 102. At the same time, the magnetic pump 5 is protected through the protective shell 104, and the air in the protective shell 104 is detected by using the gas detector 105. When the magnetic pump 5 is transporting ammonium nitrate solution, when the magnetic pump 5 leaks, the monitoring is realized through the gas detector 105;

[0059] Similarly, when the magnetic pump 5 cooperates with the delivery pipe 7 to transport the ammonium nitrate solution, through the supporting effect of the multiple groups of support plates 102 between the positioning ring 106 and the installation frame 107, the sleeve 6 and the delivery pipe 7 are supported. At the same time, through the elastic connection effect between the remaining multiple groups of springs 103 and the installation frame 107, the installation frame 107 is shock-absorbed through the remaining multiple groups of springs 103. When the magnetic pump 5 cooperates with the delivery pipe 7 to transport the ammonium nitrate solution, two-stage shock absorption treatment of the magnetic pump 5 and the sleeve 6 is realized, and the influence of the vibrations during the operation of the magnetic pump 5 on the transportation effect of the ammonium nitrate solution is avoided.

[0060] Through the elastic connection effect of the spring 103 between the support plate 102, the bottom plate 101 and the mounting frame 107, shock absorption treatment is carried out on the magnetic pump 5, the sleeve 6 and the delivery pipe 7 respectively, so as to avoid the influence of the vibration generated during the operation of the magnetic pump 5 on the ammonium nitrate solution, further ensure the delivery effect of the ammonium nitrate solution, avoid loosening between the magnetic pump 5 and the sleeve 6, and at the same time, the magnetic pump 5 is secondarily protected by the protective shell 104. Meanwhile, the gas detector 105 is used to detect the gas inside the protective shell 104, reducing the safety hazard during the delivery of the ammonium nitrate solution.

[0061] As Figures 12 to 14 shown, the cooling assembly 11 includes a second water pump 111, the second water pump 111 is installed on one side of the water storage bucket 3, the second water pump 111 is connected to the water storage bucket 3 in a through manner, the top of the second water pump 111 is connected with an electromagnetic valve 112, the number of the electromagnetic valves 112 is set to two groups, both groups of electromagnetic valves 112 are connected to the second water pump 111 in a through manner, the tops of both groups of electromagnetic valves 112 are connected with second water inlet pipes 113, the number of the second water inlet pipes 113 is set to two groups, one of the two second water inlet pipes 113 in the two groups of second water inlet pipes 113 is connected to the delivery pipe 7 in a through manner, the other of the two second water inlet pipes 113 in the two groups of second water inlet pipes 113 is nested and installed at the top end of the inner wall of the sleeve 6, a flow dividing pipe 114 is installed at the bottom end of the other of the two second water inlet pipes 113 in the two groups of second water inlet pipes 113, a spray pipe 115 is installed at the bottom end of the flow dividing pipe 114 in a through manner, the number of the spray pipes 115 is set to multiple groups, and the multiple groups of spray pipes 115 are arranged in an array at the bottom end of the flow dividing pipe 114.

[0062] During the delivery of the ammonium nitrate solution, when the temperature of the ammonium nitrate solution is too high, the control module 2 first controls the drain valve 94 at the bottom end of the heating barrel 90 to start, and quickly discharges the hot water in the heating barrel 90 through the drain valve 94. While the hot water in the heating barrel 90 is being discharged, the hot water in the heat preservation pipe 98 flows back into the heating barrel 90 and is discharged through the drain valve 94;

[0063] Subsequently, the control module 2 controls the second water pump 111 to start. After the second water pump 111 starts, it sucks the cold water stored in the water storage bucket 3. At the same time, one of the electromagnetic valves 112 starts, and the cold water sucked by the second water pump 111 is sent into the flow dividing pipe 114 through one of the second water inlet pipes 113. Under the continuous sucking action of the second water pump 111, the extracted cold water continuously enters the flow dividing pipe 114 and is sprayed out through the spray pipe 115. The delivery pipe 7 is sprayed and cooled in the sleeve 6 through the multiple groups of spray pipes 115 arranged in an array, realizing the cooling effect on the ammonium nitrate solution in the delivery pipe 7;

[0064] Meanwhile, the cold water after spraying accumulates in the sleeve 6 and enters the heating barrel 90 through the exhaust pipe 91 at the bottom end of the sleeve 6. At this time, the heating rod 95 in the heating barrel 90 is in the off state. Under the continuous suction of the cold water by the second water pump 111, the cold water after spraying is concentrated in the heating barrel 90. At the same time, the cold water after spraying enters the heat preservation pipe 98 to realize the cooling treatment of the ammonium nitrate solution stored in the heat preservation barrel 97.

[0065] Meanwhile, another group of electromagnetic valves 112 are activated and the other group of second water inlet pipes 113 send the cold water suctioned by the second water pump 111 into the conveying pipe 7 to dilute the ammonium nitrate solution in the conveying pipe 7. Under the continuous suction of the second water pump 111, the diluted ammonium nitrate solution is discharged along the conveying pipe 7.

[0066] By setting the connection effect between the second water pump 111 and the water storage bucket 3, when the temperature of the ammonium nitrate solution is relatively high, the cold water stored in the water storage bucket 3 is suctioned and utilized to spray and cool the surface of the conveying pipe 7, avoiding the high temperature of the ammonium nitrate solution conveyed in the conveying pipe 7. At the same time, by using another group of electromagnetic valves 112 and the second water inlet pipes 113, the cold water is introduced into the conveying pipe 7 to dilute the ammonium nitrate solution and reduce the oxidability and potential danger of the ammonium nitrate solution.

[0067] The working principle of the technical solution provided by the present invention is as follows:

[0068] The operator first opens the sealing door 20 and places the ammonium nitrate solution barrel on the placing table 21. Subsequently, the control module 2 controls the electric telescopic rod 81 to start. After the electric telescopic rod 81 starts, it contracts and drives the mounting plate 82 to slide downward. While the mounting plate 82 slides, it synchronously drives the suction pipe 84 and the output pipe 87 to slide downward simultaneously, and makes the suction pipe 84 enter the ammonium nitrate solution barrel. When the suction pipe 84 enters the heat preservation barrel 97, the top opening of the ammonium nitrate solution barrel is blocked by the anti-leakage ring 85 to prevent the ammonium nitrate solution from splashing. At the same time, the output pipe 87 enters the heat preservation barrel 97.

[0069] Subsequently, the control module 2 controls the centrifugal pump 83 to start. After the centrifugal pump 83 starts, it sucks out the ammonium nitrate solution in the ammonium nitrate solution barrel through the suction pipe 84 and transfers it to the heat preservation barrel 97 through the output pipe 87 for the preliminary transfer of the ammonium nitrate solution in the ammonium nitrate solution barrel.

[0070] When the ammonium nitrate solution is preliminarily transferred to the heat preservation barrel 97, the control module 2 controls the magnetic pump 5 to start. The magnetic pump 5 transports the ammonium nitrate solution in the heat preservation barrel 97 into the conveying pipe 7 and transports the ammonium nitrate solution to the expanded ammonium nitrate explosive production container through the conveying pipe 7.

[0071] During this process, the control module 2 controls the heating rod 95 to start, heats the water stored in the heating barrel 90 through the heating rod 95, and makes the water in the heating barrel 90 boil and generate water vapor. The steam in the heating barrel 90 enters the sleeve 6 through the exhaust pipe 91 at the top of the heating barrel 90, and accumulates in the cavity formed between the sleeve 6 and the conveying pipe 7, and continuously heats the conveying pipe 7 through the steam, heating and keeping warm the ammonium nitrate solution passing through the conveying pipe 7. At the same time, the liquid level sensor 96 is used to detect the liquid level height of the water in the heating barrel 90 in real time, and the obtained data is transmitted to the control module 2 through an electrical signal. When the water in the heating barrel 90 decreases, the control module 2 controls the valve 93 to open, and the water stored in the water storage barrel 3 is supplemented into the heating barrel 90 through the valve 93 and the water supply pipe 92, realizing the real-time supplement of the water in the heating barrel 90, ensuring the continuity of the heating effect of the heating barrel 90 on the conveying pipe 7, so that the temperature of the ammonium nitrate solution conveyed in the conveying pipe 7 meets the processing requirements.

[0072] While the heating rod 95 heats the water in the heating barrel 90, the heated water in the heating barrel 90 simultaneously enters the heat preservation pipe 98. Through the spiral structure of the heat preservation pipe 98, a heat preservation layer is formed in the inner cavity of the heat preservation pipe 98, and the ammonium nitrate solution in the heat preservation barrel 97 is heat-preserved by the water heated in the heat preservation pipe 98.

[0073] After the magnetic pump 5 is started, the magnetic pump 5 is supported by the connection effect between the bottom plate 101 and the support plate 102. At the same time, after the magnetic pump 5 starts to operate, the magnetic pump 5 generates vibrations during operation. The spring 103 elastically connected between the bottom plate 101 and the support plate 102 dampens the vibrations generated during the operation of the magnetic pump 5. At the same time, the magnetic pump 5 is protected by the protective shell 104, and the air in the protective shell 104 is detected by the gas detector 105. When the magnetic pump 5 is transporting ammonium nitrate solution, when the magnetic pump 5 leaks, it is monitored by the gas detector 105.

[0074] Similarly, when the magnetic pump 5 cooperates with the conveying pipe 7 to convey the ammonium nitrate solution, the sleeve 6 and the conveying pipe 7 are supported by the supporting effect of multiple groups of support plates 102 between the positioning ring 106 and the installation frame 107. At the same time, through the elastic connection effect between the remaining multiple groups of springs 103 and the installation frame 107, the remaining multiple groups of springs 103 dampen the installation frame 107. When the magnetic pump 5 cooperates with the conveying pipe 7 to convey the ammonium nitrate solution, two-stage shock absorption treatment of the magnetic pump 5 and the sleeve 6 is realized, avoiding the influence of the vibrations during the operation of the magnetic pump 5 on the conveying effect of the ammonium nitrate solution.

[0075] After the transfer of the ammonium nitrate solution is completed, the control module 2 controls the electric telescopic rod 81 to start again. After the electric telescopic rod 81 starts, it extends and resets, driving the mounting plate 82 to slide upward. While the mounting plate 82 slides, it synchronously drives the suction pipe 84 and the output pipe 87 to slide upward simultaneously, causing the suction pipe 84 to disengage from the ammonium nitrate solution bucket and the output pipe 87 to disengage from the heat preservation bucket 97. At the same time, the control module 2 controls the first water pump 99 to start. After the first water pump 99 starts, it pumps out the hot water in the heat preservation pipe 98 and sprays it out through the spray pipe 910.

[0076] After the hot water is sprayed out, it slides down along the surface of the suction pipe 84 under the action of gravity and drips through the diversion groove 86. During this process, the surface of the suction pipe 84 is cleaned with the hot water, and the ammonium nitrate solution contaminated on the surface of the suction pipe 84 is cleaned. At the same time, while the output pipe 87 slides, it passes by and contacts the diversion ring 88. Under the scraping action of the diversion ring 88, the ammonium nitrate solution contaminated on the surface of the output pipe 87 is scraped off, and under the guiding action of the diversion ring 88 and the action of gravity, the scraped ammonium nitrate solution drips into the heat preservation bucket 97.

[0077] During the transfer of the ammonium nitrate solution, when the temperature of the ammonium nitrate solution reaches between 110°C and 140°C (to ensure safe transportation, when the concentration of ammonium nitrate is not less than 93%, the filling temperature of liquid ammonium nitrate is controlled at 140°C, and the maximum is not allowed to exceed 150°C), when a high-temperature warning is reached, the control module 2 first controls the drain valve 94 at the bottom of the heating bucket 90 to start, and quickly discharges the hot water in the heating bucket 90 through the drain valve 94. While the hot water in the heating bucket 90 is being discharged, the hot water in the heat preservation pipe 98 flows back into the heating bucket 90 and is discharged through the drain valve 94.

[0078] Subsequently, the control module 2 controls the second water pump 111 to start. After the second water pump 111 starts, it sucks the cold water stored in the water storage bucket 3. At the same time, one group of electromagnetic valves 112 starts, sending the cold water sucked by the second water pump 111 into the shunt pipe 114 through one group of second inlet pipes 113. Under the continuous suction of the second water pump 111, the extracted cold water continuously enters the shunt pipe 114 and is sprayed out through the spray pipe 115. The conveying pipe 7 is cooled by spraying through multiple groups of spray pipes 115 arranged in an array in the sleeve 6, achieving the cooling effect of the ammonium nitrate solution in the conveying pipe 7.

[0079] At the same time, the sprayed cold water accumulates in the sleeve 6 and enters the heating bucket 90 through the exhaust pipe 91 at the bottom of the sleeve 6. At this time, the heating rod 95 in the heating bucket 90 is in the off state. Under the continuous suction of cold water by the second water pump 111, the sprayed cold water is concentrated in the heating bucket 90, and at the same time, the sprayed cold water enters the heat preservation pipe 98, realizing the cooling treatment of the ammonium nitrate solution stored in the heat preservation bucket 97.

[0080] Meanwhile, another group of solenoid valves 112 are activated and another group of second water inlet pipes 113 send the cold water pumped by the second water pump 111 into the conveying pipe 7 to dilute the ammonium nitrate solution in the conveying pipe 7. Under the continuous suction of the second water pump 111, the diluted ammonium nitrate solution is discharged along the conveying pipe 7.
