Description

Technical Field

[0001] The utility model relates to the technical field of explosive production, in particular to an explosive filtering and buffering device. Background Art

[0002] Domestic production of explosive molding powder primarily utilizes a water suspension granulation process and hot air drying, which can easily introduce iron impurities. Furthermore, impurities such as sawdust, paper scraps, and cotton wool can affect the powder's fluidity, requiring filtration during production.

[0003] The invention patent currently published with the publication number CN204918416U discloses an emulsion explosive filtering device. The outer packaging film of the waste drug to be processed is first peeled off and added to the material cylinder. The material cylinder is then rotated to the position directly below the piston and the power device is started. Under the action of the piston pressure, the waste drug is filtered through the filter screen and falls into the material cart below the device. By providing a rotating workbench with two symmetrically distributed double material cylinders, the processing efficiency of the waste drug can be greatly accelerated and the recovery speed can be improved. This solves the problem that the waste drug is a colloidal and viscous substance, and the negative pressure of the screw pump is insufficient to suck the waste drug into the filter, which greatly reduces the processing efficiency. Moreover, for the centralized recovery and processing production line of emulsion explosives, the traditional single-line design of the filtration process is far from meeting the needs of multi-station adjustment and adaptation, which reduces the overall processing efficiency and makes it difficult to effectively increase the average daily recovery and processing volume of emulsion explosives.

[0004] During the filtering process of explosives, the feeding device directly discharges the explosives into the filter. When the explosives fall rapidly, a large amount of powder will be generated, which not only leads to increased loss of explosives, but also makes it easy to explode when the explosive content in the air increases, reducing the safety of explosives production. In order to solve the above problems, this application proposes an explosives filtering buffer device. Utility Model Content

[0030] It should be noted that the filtered explosives fall on the upper buffer inclined plate 4, and under the action of gravity, the explosives slide to the lowest point of the upper buffer inclined plate 4, and fall onto the lower buffer inclined plate 5 through the discharge chute 10, and then the explosives are discharged by the lower buffer inclined plate 5. The discharge guide groove 11 can guide the discharge of the explosives, slow down the falling speed of the explosives, and improve the safety of the explosives during filtering. The top adjustment fixing sleeve 7 and the bottom adjustment fixing sleeve 8 can be moved on the mounting column 3, and the top adjustment fixing sleeve 7 and the bottom adjustment fixing sleeve 8 are locked by the locking screw.

By adjusting the angle of the upper buffer inclined plate 4 and the lower buffer inclined plate 5, the sliding speed of the explosives can be adjusted during use to improve the safety during explosives production.

[0031] In this embodiment, if Figure 2 and Figure 3 As shown, the ends of the telescopic connecting rod 9 are rotatably connected to the top adjustment fixing sleeve 7 and the bottom adjustment fixing sleeve 8 respectively.

[0032] It should be noted that when the angles of the upper buffer inclined plate 4 and the lower buffer inclined plate 5 change, the telescopic connecting rod 9 can be stretched or compressed, so that the upper buffer inclined plate 4 and the lower buffer inclined plate 5 can be connected to the top adjustment fixing sleeve 7 and the bottom adjustment fixing sleeve 8.

The support spring 13 and the damper 15 can be matched to buffer the vibration, so as to improve the stability of the buffer device during use.

[0039] The working principle and use process of the utility model are as follows: the filtered explosives fall on the upper buffer inclined plate 4, and under the action of gravity, the explosives slide to the lowest point of the upper buffer inclined plate 4 and fall onto the lower buffer inclined plate 5 through the discharge chute 10, and then the explosives are discharged by the lower buffer inclined plate 5. The discharge guide groove 11 can guide the discharge of the explosives, slow down the falling speed of the explosives, and improve the safety of the explosives during filtering. The top adjustment fixing sleeve 7 and the bottom adjustment fixing sleeve 8 can be moved on the mounting column 3, and the top adjustment fixing sleeve 7 and the bottom adjustment fixing sleeve are tightened by the locking screw. 8 is locked, and the telescopic connecting rod 9 can be stretched or compressed when the angles of the upper buffer inclined plate 4 and the lower buffer inclined plate 5 change.
