Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of puffed explosive, especially relates to a device for preventing material blocking during vacuum extraction of puffed tank. BACKGROUND

[0002] At present, in the production process of puffed explosive, the vacuum pipeline is often blocked, and the phenomenon of nozzle around being blocked occurs, causing the problem of subsequent discharging not smooth and vacuum not up to standard. The traditional method is to clean the vacuum pipeline by manual operation with a special tool, or to drill into the tank to clean the material adhered around the nozzle, which is laborious, time-consuming and unsafe. Subsequently, there are devices that use high-frequency vibration or rotation to avoid blockage, but these devices are often complex in structure, large in floor space, and have a low anti-blocking rate. Therefore, it is an urgent task to design a simple structure to prevent blockage.

[0003] A Chinese utility model with application number CN202023091219.7 discloses a puffed ammonium nitrate explosive production equipment anti-blocking structure, which includes a material box. The top of the material box is provided with a feeding port. The bottom of the material box is provided with a discharging pipe. The inside of the material box is provided with a spiral auger. The spiral auger is installed on a driving shaft. The driving shaft is connected to a driving motor through a shaft coupling. The driving motor is fixedly connected to the bottom of the material box through a fixing frame. The driving shaft is provided with an anti-blocking assembly corresponding to the discharging pipe. This utility model uses vibration to reduce the probability of vacuum pipeline blockage, which is effective but not ideal in terms of processing vacuum pipeline blockage rate. Moreover, the device is complex in structure, difficult to disassemble and maintain, and inconvenient for users. UTILITY MODEL CONTENTS

[0004] The utility model aims to provide a device for preventing material blocking during vacuum extraction of puffed tank, which solves the problem of vacuum pipeline and nozzle being blocked in the production process of puffed explosive, as well as the problems of traditional anti-blocking device, such as complex structure, large floor space, and difficult maintenance operation.

[0005] Therefore, a device for preventing material blocking during vacuum extraction of puffed tank is proposed, which includes a first pipeline. The right side of the first pipeline is provided with a booster chamber. The right side of the booster chamber is provided with a second pipeline. The lower side of the second pipeline is provided with a spray head. The spray head is internally provided with a threaded rod. The threaded rod is fixedly inclined to the side surface of the spray head through a locking nut. The end of the threaded rod extending into the interior of the spray head is further provided with a spherical stopper. The spherical stopper is located above the spray hole at the bottom of the spray head.

[0006] The effect is as follows: the material enters the pressurization chamber through the first pipe for initial pressurization, then enters the nozzle through the second pipe for a second pressurization, and finally, the material is sprayed downwards as a fine mist. At this point, the threaded rod on the side of the nozzle and the spherical blocker at the end of the threaded rod suspend the spherical blocker above the nozzle's bottom orifice, causing the sprayed material to form a fan shape. This effectively reduces the reverse impact force of the material hitting the ground, and the scraper can more quickly scrape the expanded material to the conveying screw, thereby reducing blockage in the vacuum pipe and around the nozzle. The locking nut secures the threaded rod. The spherical blocker, positioned above the nozzle's bottom orifice, is key to forming the fan-shaped spray.

[0007] A further improvement is that the threaded rod can be rotated to adjust the distance between the spherical plug and the nozzle.

[0008] The effect is that by adjusting the distance between the spherical blocker and the nozzle at the bottom of the nozzle, the angle of the material sprayed out in a fan shape can be adjusted, making it easier for the scraper to scrape away the expanded material to the conveying screw more quickly.

[0009] A further improvement is that a handle is provided at the other end of the threaded rod.

[0010] The benefit is that the handle allows users to easily adjust it according to production conditions.

[0011] A further improvement is that the first pipe structure is a straight pipe, and the second pipe structure is a right-angle bend.

[0012] The effect is that this structure facilitates the transport of materials.

[0013] A further improvement is that the second pipe and the nozzle are fixedly connected by threads.

[0014] The advantage is that the threaded connection makes it easy for users to disassemble and repair.

[0015] A further improvement is that the distance between the nozzle and the second pipe is adjusted by rotating the screw thread.

[0016] The effect is that the height of the nozzle can be adjusted by rotating the screw, reducing the time that materials stay in the air, so that the scraper can scrape away the materials more quickly, thereby avoiding blockage of the vacuum pipe.

[0017] A further improvement is that the nozzle has an inverted funnel-shaped structure.

[0018] The effect is that the funnel-shaped nozzle is more in line with actual production and can significantly improve equipment operating efficiency.

[0019] A further improvement is that the nozzle has one or more spray holes at its bottom.

[0020] The effect is that if this invention is installed on larger mechanical equipment, the nozzle will also be larger and more nozzles will be needed to keep up with production efficiency; conversely, smaller equipment can use fewer or even a single nozzle.

[0021] Beneficial effects

[0022] This invention provides a device for vacuuming and preventing material blockage in an expansion tank. It first pressurizes the material in a pressurizing chamber, conveying it to the nozzle. A second pressurization occurs within the nozzle, propelling the material at high speed from the nozzle orifice. A spherical blocker inside the nozzle ensures the ejected material forms a fan-shaped mist. The angle of the fan-shaped mist can be adjusted by regulating the screw, effectively reducing the reverse impact force of the material upon impact. The scraper quickly removes the expanded material to the conveying screw, thus reducing the likelihood of blockage in the vacuum pipeline and around the nozzle. Furthermore, this invention features a simple structure, is easy to operate, and can be adjusted to suit other equipment models, significantly improving the user experience.
