Description

Technical Field

[0001] The utility model relates to the technical field of emulsion explosive production, in particular to an automatic control device for sensitized temperature of emulsion explosive. Background Art

[0002] Emulsion explosives are dispersed phases of droplets of oxidant aqueous solution suspended in a phase-continuous medium containing dispersed bubbles or other porous oil-like substances, forming a water-in-oil (W / O) latex-like aqueous industrial explosive. Emulsion explosives are phase-continuous media composed of oil substances. After adding a foaming agent to the latex matrix, a large number of uniform bubbles are generated to meet the medium requirements. Under normal circumstances, the speed, size and number of bubbles generated by the latex matrix under the action of the foaming agent are related to the temperature. It is necessary to control the temperature of the emulsion explosive matrix to always be 84℃~86℃ and the fluctuation amplitude is small in order to produce the best quality products. The current production line uses the Dibotai RCEG2-12L Rota-Clip packaging system, and the central control room uses SIMATICWinCC software to monitor the production line. The current temperature control system of the production line consists of a temperature transmitter to monitor the discharge temperature, a SIMATICWinCC software discharge temperature alarm, and a manual water valve. Therefore, this system cannot be used without human monitoring. The operators in the central control room can only observe the temperature but cannot control it. Only when the operators in the central control room receive the temperature alarm information and notify the operators on the production line can the discharge temperature be manually controlled. During the normal operation of the equipment, the discharge temperature fluctuates greatly and frequently. A lot of labor is spent on solving the problem of discharge temperature on site, which causes large fluctuations in product performance indicators. The sensitization process of adding foaming agent to the matrix is ​​always an exothermic reaction, and the reaction speed and heat release are different. If the temperature is not controlled in time, it will cause the temperature to rise and fall sharply, which will not only produce unqualified products but also pose a safety hazard.

[0005] An automatic control device for sensitizing temperature of emulsion explosives comprises a sensitizer body, a side of which is connected with a discharge pipe;

[0006] A heat preservation cavity is provided outside the sensitizer body;

[0007] It also includes a water inlet pipe, which is in communication with the heat preservation chamber, the water inlet pipe is connected to a ball valve and a pneumatic butterfly valve, and the pneumatic butterfly valve is connected to a solenoid valve;

[0008] It also includes a temperature transmitter, wherein the sensing component of the temperature transmitter is arranged on the inner wall of the medicine outlet pipe;

[0009] The device also includes a controller, which is electrically connected to the temperature transmitter and the solenoid valve respectively.

[0010] Furthermore, in the structure of the automatic control device for sensitizing temperature of emulsion explosives, the pneumatic butterfly valve is located between the cold water inlet end of the water inlet pipe and the ball valve.

[0011] Furthermore, the structure of the automatic control device for sensitization temperature of emulsion explosives further includes a host computer, and the host computer is electrically connected to the controller.

[0012] Furthermore, in the above-mentioned automatic control device structure for sensitization temperature of emulsion explosive, the controller is a PLC.

[0013] Furthermore, in the structure of the automatic control device for sensitization temperature of emulsion explosives, the host computer is a device storing SIMATIC WinCC software and having the ability to run the software.

[0014] Furthermore, in the above-mentioned automatic control device structure for sensitizing temperature of emulsion explosive, an outer wall of the discharge pipe is provided with a heat-insulating layer.

[0015] Furthermore, in the above-mentioned automatic control device structure for sensitizing temperature of emulsion explosive, the heat preservation chamber is connected with a drainage pipe.

[0016] The beneficial effect of the utility model is that by adding a pneumatic butterfly valve and a solenoid valve to the water inlet pipe and adding a temperature transmitter to the medicine outlet pipe, the opening of the pneumatic butterfly valve of the water inlet pipe can be timely adjusted according to the temperature of the medicine outlet pipe. When the heat release changes during the sensitization process, the water inlet volume can be adjusted by adjusting the opening of the pneumatic butterfly valve in time, thereby automatically controlling the temperature of the sensitizer, avoiding the phenomenon of rapid temperature rise and fall, reducing the product failure rate and improving safety.

[0030] As a preferred embodiment, the outer wall of the drug outlet pipe 8 is provided with a heat-insulating layer 9 .

[0031] As a preferred embodiment, the heat preservation chamber is connected to a drain pipe 11 .

[0032] In the above implementation, the RCEG2-12L Rota-Clip sensitization system uses PLC6 to realize data transmission. To realize the temperature control solution, a pneumatic butterfly valve 2 is installed above the original valve of the water inlet pipe 5, and a solenoid valve 3 is installed on the pneumatic butterfly valve 2, and an air pipe is connected to the solenoid valve 3 to supply air.

[0033] After adding an automatic temperature control program to the PLC6 program, connect the solenoid valve 324V+ interface to an output point of PLC6 to achieve this.

[0034] A temperature controller is installed on the sensitized drug outlet pipe 8, and the data of the temperature controller is connected to the PLC6.

[0035] Add a valve icon to the SIMATIC WinCC software control interface on the computer (host computer) in the central control room to associate it with the output point of the solenoid valve 3 of the PLC6 program, and add the temperature upper limit setting, temperature lower limit setting and butterfly valve switch ratio box on the interface.

[0037] Example 1

[0038] (1) Equipment selection

[0039] The pipeline water volume control valve is selected as a pneumatic butterfly valve 2, which is installed above the original ball valve 4.

[0043] By using the implanted operation logic instructions in PLC6 and the temperature transmitter 7, the temperature transmitter 7 obtains the sensitized outlet temperature of the emulsion explosive. If the temperature is higher than the upper limit temperature set on the SIMATICWinCC software, all the pneumatic butterfly valves 2 will be opened, and the cold water will cool down the sensitized outlet of the emulsion explosive to make the temperature return to the temperature control area; if the temperature obtained by the temperature transmitter 7 is lower than the lower limit temperature set on the SIMATICWinCC software, the pneumatic butterfly valve 2 will be closed to make the temperature return to the temperature control area; if the temperature obtained by the temperature transmitter 7 is within the upper and lower limit temperature range set on the SIMATICWinCC software, the corresponding scale pneumatic butterfly valve 2 switch will be opened according to the temperature situation, so that the sensitized temperature is always kept within the set range.
