Description

Technical Field

[0001] The utility model relates to an initiating agent detection device, in particular to a liquid initiating agent state detection device. Background Art

[0002] The drip coating process of liquid pyrotechnic agent is a common technical process in the processing of pyrotechnic products. During the drip coating process, the state of the liquid pyrotechnic agent needs to be monitored to ensure that its viscosity, solvent ratio and liquid consistency remain in a reasonable state.

[0003] During the drip coating process, factors such as solvent volatilization and temperature changes may cause the state of the liquid pyrotechnic agent in the medicine bowl to change, making it unable to meet the process requirements of the drip coating operation. For example, due to solvent volatilization, the viscosity of the agent increases and the solute / solvent ratio increases. At this time, it is necessary to add solvent to the medicine bowl to dilute the agent. After stirring evenly, the operation can be continued to confirm when to add solvent. Since the state of liquid pyrotechnic agents is sensitive, easy to explode, and highly dangerous, transmission electromagnetic sensors cannot be used in this case. The existing technical solution is to manually observe and stir with a stirring rod to confirm the state of the agent in the medicine bowl, and then determine whether to add solvent. This consumes manpower and material resources, and the detection accuracy may not be guaranteed, and the consistency of the product cannot be guaranteed. Summary of the invention

[0004] The purpose of the utility model is to provide a device for detecting the state of liquid pyrotechnic agent. The utility model detects the viscosity of the agent in real time during the stirring process by a torque sensor. When the viscosity is too high, the viscosity of the liquid medicine is automatically diluted by a solvent adding component, thereby avoiding the situation of manual detection of the liquid medicine in the medicine bowl. This solves the problem of manual observation and stirring with a stirring rod to confirm the state of the medicine in the medicine bowl during actual use, and then determining whether to add solvent, which consumes manpower and material resources, and the detection accuracy may not be guaranteed, and the consistency of the product cannot be guaranteed.

[0005] The utility model adopts the following technical solutions:

[0006] A device for detecting the state of a liquid pyrotechnic agent comprises a working platform, a longitudinal mounting plate and a medicine bowl located at the top of the working platform, wherein a horizontal sliding component for driving the longitudinal mounting plate to slide back and forth in a horizontal direction is detachably mounted on the top of the working platform, a mounting platform that can slide back and forth in the longitudinal direction is mounted on one side of the longitudinal mounting plate, a stirring component for stirring the medicine bowl is mounted on the end face of the mounting platform, the stirring component comprises a rotatable shaft, a torque sensor is detachably mounted on the top of the shaft, and a solvent adding component for diluting the internal concentration of the medicine bowl is mounted on one side of the stirring component.

[0007] As a preferred solution of the utility model, the top end of the torque sensor is connected to a motor, the detection end of the torque sensor is connected to the top end of the rotating shaft, and a plurality of stirring rods are arranged at the bottom of the rotating shaft.

[0008] As a preferred solution of the utility model, the solvent adding component can be detachably installed on one side of the mounting platform, and the solvent adding component includes a tank body with a solvent inside, a partition for guiding is arranged inside the tank body, a sealing column which can slide back and forth in the longitudinal direction is arranged on the inner side of the partition, a discharge port is opened on the part of the tank body located inside the partition, the bottom of the tank body is connected to the discharge port, and a solvent delivery pipe is sleeved on the outer side of the discharge port.

[0009] As a preferred solution of the utility model, a lifting rod for driving the sealing column to rise and fall is installed on the top of the tank body, and a slot is provided on the inner side of the partition at the bottom of the tank body. When the bottom end of the sealing column fits in the slot, the solvent cannot flow out from the discharge port.

[0010] As a preferred solution of the utility model, the mounting platform is located below the solvent adding assembly and is detachably mounted with a support frame for supporting and fixing the solvent delivery pipe, and the liquid outlet of the solvent delivery pipe can inject the solvent into the interior of the medicine bowl.

[0011] As a preferred solution of the utility model, a lifting slide rail is installed on one side of the longitudinal mounting plate, a lifting cylinder is detachably installed on the top of the longitudinal mounting plate, a limit block is installed on one side of the mounting platform, the lifting cylinder can drive the limit block to slide reciprocatingly, the mounting platform can slide reciprocatingly along the lifting slide rail, and a buffer component located below the mounting platform is installed at the bottom end of one side of the longitudinal mounting plate.

[0012] The technical effects and advantages provided by the utility model are:

[0013] When the stirring rod of the utility model starts to stir inside the medicine bowl, the torque sensor detects the torque in real time. When the medicine in the medicine bowl becomes viscous due to the volatilization of the solvent, the resistance encountered by the stirring rod in the liquid medicine becomes larger. At this time, the torque data detected by the torque sensor becomes larger. When the torque data detected by the torque sensor exceeds the preset threshold, the software system determines that the medicine is too viscous to meet the requirements of the dripping operation. At this time, the shaft stops rotating, the lifting rod is lifted, and the corresponding mass solvent is transmitted to the inside of the medicine bowl through the solvent delivery pipe to dilute the medicine liquid inside the medicine bowl. After the medicine liquid is diluted, it is stirred and tested again. If the torque parameters meet the preset requirements, it means that the medicine state meets the requirements and the dripping operation can be carried out. The shaft resistance is detected by using a torque sensor, and the viscosity of the medicine is detected in real time during the stirring process. When the viscosity is too high, the viscosity of the medicine liquid can be automatically diluted by the solvent addition component, avoiding manual detection of the medicine liquid in the medicine bowl, improving the detection accuracy, reducing the cumbersome operation steps, reducing the workload of workers, and ensuring the quality of the product.

[0019] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0020] The utility model provides Figure 1-4A liquid pyrotechnic agent state detection device shown in the figure includes a working platform 8, a longitudinal mounting plate 2 and a medicine bowl 5 located at the top of the working platform 8, the top of the working platform 8 is detachably mounted with a horizontal sliding component 6 for driving the longitudinal mounting plate 2 to slide back and forth in the horizontal direction, one side of the longitudinal mounting plate 2 is mounted with a mounting platform 1 that can slide back and forth in the longitudinal direction, the end face of the mounting platform 1 is mounted with a stirring component 4 for stirring the medicine bowl 5, the stirring component 4 includes a rotatable shaft 403, the top of the shaft 403 is detachably mounted with a torque sensor 402, one side of the stirring component 4 is mounted with a solvent adding component 7 for diluting the internal concentration of the medicine bowl 5, the height and position of the stirring component 4 can be adjusted by the longitudinal and lateral sliding of the mounting platform 1, so that the stirring rod 404 can be accurately moved to the inside of the medicine bowl 5 for stirring, and can adapt to medicine bowls 5 of different sizes to improve the applicability of the product.

[0021] The top of the torque sensor 402 is connected to the motor 401, and the detection end of the torque sensor 402 is connected to the top of the rotating shaft 403. A plurality of stirring rods 404 are arranged at the bottom of the rotating shaft 403. The stirring rods 404 are detachably installed at the bottom of the rotating shaft 403. By increasing the length of the stirring rods 404 or changing the style of the stirring rods 404, the difficulty of the solvent delivery tube 701 to inject the solvent into the medicine bowl 5 can be reduced, thereby reducing or avoiding the splashing of the solvent.

[0022] The solvent adding component 7 can be detachably installed on one side of the mounting platform 1, and the solvent adding component 7 includes a tank body 702 with a solvent inside, and a baffle 707 for guiding is arranged inside the tank body 702, and a sealing column 704 which can slide back and forth in the longitudinal direction is arranged on the inner side of the baffle 707, and a discharge port 706 is opened on the part of the tank body 702 located inside the baffle 707, and the bottom of the tank body 702 is connected with the discharge port 706, and a solvent delivery pipe 701 is sleeved on the outer side of the discharge port 706. The solvent adding component 7 is arranged above the medicine bowl 5, and can make the liquid flow out by gravity. The size of the sealing column 704 is matched with the size of the inner side of the baffle 707, and can completely block the discharge port 706 to prevent solvent leakage.

[0023] A lifting rod 705 for driving the sealing column 704 to rise and fall is installed at the top of the tank body 702. A card slot 703 is provided at the bottom of the tank body 702 located inside the partition 707. When the bottom end of the sealing column 704 is in contact with the card slot 703, the solvent cannot flow out from the discharge port 706. By controlling the lifting and lowering of the sealing column 704, whether the solvent flows out is controlled. By controlling the lifting time, the quality of the outflowing solvent is controlled, thereby achieving the purpose of diluting the drug solution.

[0024] The mounting platform 1 is located below the solvent adding assembly 7 and is detachably mounted with a support frame 10 for supporting and fixing the solvent delivery tube 701. The liquid outlet of the solvent delivery tube 701 can inject the solvent into the medicine bowl 5. The solvent delivery tube 701 is fixed and guided by the support frame 10 so that the solvent delivery tube 701 can inject the solvent into the medicine bowl 5 along the gap between the medicine bowl 5 and the stirring rod 404 without interfering with the rotation of the stirring assembly 4, thereby achieving the addition of solvent without lifting the stirring rod 404.

[0025] A lifting rail 3 is installed on one side of the longitudinal mounting plate 2, and a lifting cylinder 11 is detachably installed on the top of the longitudinal mounting plate 2. A limit block 12 is installed on one side of the mounting platform 1. The lifting cylinder 11 can drive the limit block 12 to slide back and forth, and the mounting platform 1 can slide back and forth along the lifting rail 3. A buffer component 9 located below the mounting platform 1 is installed at the bottom end of one side of the longitudinal mounting plate 2. The buffer component 9 is an elastic rebound mechanism. When the mounting platform 1 reaches the lower end buffer component 9, it rebounds and decelerates, ensuring that the stirring rod 404 is slowly immersed in the medicine to avoid the medicine splashing everywhere and causing safety hazards.

[0026] In the utility model, when the stirring rod 404 starts to stir inside the medicine bowl 5, the torque sensor 402 detects the torque in real time. When the medicine in the medicine bowl 5 becomes viscous due to the volatilization of the solvent, the resistance encountered by the stirring rod 404 in the liquid medicine becomes larger. At this time, the torque data detected by the torque sensor 402 becomes larger. When the torque data detected by the torque sensor 402 exceeds the preset threshold, the software system determines that the medicine is too viscous to meet the requirements of the dripping operation. At this time, the rotating shaft 403 stops rotating, the lifting rod 705 is lifted, and the corresponding mass solvent is transmitted to the inside of the medicine bowl 5 through the solvent delivery pipe 701 to dilute the medicine solution in the medicine bowl 5. After the medicine solution is diluted, it is stirred and tested again. If the torque parameter meets the preset requirements, it means that the state of the medicine meets the requirements and the dripping operation can be performed. The torque sensor 402 is used to detect the resistance of the rotating shaft 403, and the viscosity of the medicine is detected in real time during the stirring process. When the viscosity is too high, the viscosity of the medicine solution can be automatically diluted by the solvent addition component 7, thereby avoiding manual detection of the medicine solution in the medicine bowl 5, improving the detection accuracy, reducing the cumbersome operation steps, reducing the workload of workers, and ensuring the quality of the product.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
