Description

Technical Field

[0001] The utility model relates to the technical field of industrial explosive production, in particular to a device for preventing ammonium nitrate from expanding and clogging a vacuum pipeline. Background Art

[0002] Currently, the production of expanded explosives relies on vacuum drying of ammonium nitrate solution. During the drying process, the vacuum lines often become clogged with ammonium nitrate particles or dust, severely impacting the vacuum level. On average, the vacuum lines must be cleaned 2-4 times per eight-hour shift. The 5-6-meter-long vacuum lines are a significant challenge.

[0003] Chinese utility model application number CN202323177625.9 discloses a device for dealing with explosive blockage, including a conical salvage tube, three copper rods welded to one end of the conical salvage tube discharge port, and one end of the three copper rods is connected to a threaded joint. The three copper rods are evenly arranged in a circular array at one end of the conical salvage tube discharge port, and one end of the conical salvage tube feed port is provided with a conical seal for sealing the conical salvage tube feed port through an adjustment mechanism. The adjustment mechanism includes a rotating rod rotatably arranged at the bottom end of the threaded joint, and one end of the rotating rod is provided with an external thread. This utility model does not solve the above-mentioned technical defects. Utility Model Content

[0004] In order to solve the problem of blockage of vacuum pipes caused by the use of expanded explosives, as well as the problem of complicated cleaning and excessive cleaning times, the present application proposes a device to prevent ammonium nitrate from expanding and clogging vacuum pipes.

[0005] To this end, the present application proposes a device for preventing ammonium nitrate from expanding and clogging a vacuum pipe, comprising a rotating chassis provided with an expanded ammonium nitrate discharge port; an expanding tank is also provided above the rotating chassis, and a central axis is provided at the center of the expanding tank; a liquid ammonium nitrate pipe is provided on the side wall of the expanding tank, the liquid ammonium nitrate pipe leads to the interior of the expanding tank, a liquid ammonium nitrate nozzle is provided at the outlet of the internal liquid ammonium nitrate pipe, and a scraper is also provided inside the expanding tank, characterized in that: a vacuum pipe is provided on the expanding tank, an anti-blocking hole device is provided below the vacuum pipe, a screen is provided below the anti-blocking hole device, and the interior of the anti-blocking hole device is through-connected from top to bottom; the anti-blocking hole device has an appearance of a truncated cone, and finally the anti-blocking hole device as a whole presents an internally through-connected truncated cone shape that is wide at the top and narrow at the bottom.

[0006] The advantages of the present invention are as follows: the vacuum duct in the present invention is positioned above the anti-blocking device. When the vacuum duct is in operation, the anti-blocking device effectively filters particulate impurities within the expanded container, preventing clogging of the vacuum duct. The screen provided below the anti-blocking device can filter out larger particles during the initial filtration. A vertically continuous anti-blocking device allows for better particle filtration. The anti-blocking device is designed to be internally continuous, wide at the top, and narrow at the bottom in a truncated cone shape. This increases air flow during filtration, improves impurity filtration quality, and enhances the overall filtration effect and performance of the device.

[0007] Further improvements are: the cross-sectional diameter of the wide side of the anti-hole blocking device is Φ500±50㎜; the cross-sectional diameter of the narrow side is Φ300±50㎜; and the height of the anti-hole blocking device is 500±50㎜.

[0008] The effect is that the anti-blocking hole is equipped with such a specification value to further optimize the filtering effect of the utility model.

[0009] A further improvement is that the anti-hole blocking device and the vacuum pumping pipe are concentric and coaxial, and the distance between the anti-hole blocking device and the vacuum pumping pipe is 200±30㎜.

[0010] The effect is that the distance between the anti-blocking device and the vacuum pipe is set to 200±30㎜, which will not cause the anti-blocking device to be overloaded and cause the problem of frequent replacement of screens and filters, and can also effectively filter particles and reduce the number of regular cleaning of blockages.

[0011] A further improvement is that the cross-sectional diameter of the vacuum pipe is Φ250±50㎜.

[0012] The effect is: the cross-sectional diameter of the vacuum pipe is Φ250±50㎜, which further improves the particle filtration effect.

[0013] A further improvement is that the scraper is fixed on the expanded ammonium nitrate discharge port, with one end facing the expanded ammonium nitrate discharge port and the other end facing the central axis.

[0014] The effect is that the scraper arranged in this way can clean up the larger particles settled at the bottom, reducing the operating pressure of the anti-hole blocking device and the vacuum pipeline above.

[0015] A further improvement is that the screen is detachable.

[0016] The effect is that the detachable screen is more convenient and quicker to clean regularly, greatly improving the user experience. Beneficial effects

[0017] The utility model proposes a device for preventing ammonium nitrate from expanding and clogging the vacuum pipe, which effectively improves the problem of vacuum pipe being clogged after the use of expanded explosives, solves the problem of complicated cleaning after blockage, and the problem of frequent regular cleaning. On the other hand, the utility model has a simple structure and strong universality, and brings a better user experience as a whole. BRIEF DESCRIPTION OF THE DRAWINGS
