Description

Technical Field

[0001] This utility model relates to the field of potassium perchlorate processing for firecrackers, and more particularly to a potassium perchlorate processing device for firecrackers. Background Technology

[0002] In the manufacture of firecracker gunpowder, potassium perchlorate typically needs to be mixed with other components such as fuel and binders. To ensure uniform mixing and improve the performance and safety of the gunpowder, grinding is a common step. Grinding reduces the size of the potassium perchlorate particles, increasing their surface area and thus improving reaction efficiency.

[0003] Existing technologies employ batch grinding, which results in low grinding efficiency. Therefore, based on this technical problem, we designed a potassium perchlorate processing device for firecrackers that enables continuous grinding and is less prone to clogging. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a potassium perchlorate processing device for firecrackers, including a toothed disc crusher shell, a side cover, a moving toothed disc, a negative pressure fan, and a collection chamber; the moving toothed disc is arranged inside the toothed disc crusher shell, and two rings of movable crushing rods are arranged in a circular array on the moving toothed disc. The moving toothed disc is driven to rotate by a motor on one side of the toothed disc crusher shell. An annular filter screen is arranged on the outer ring of the moving toothed disc, and an annular mounting groove is provided at the opening of the toothed disc crusher shell. An annular mounting groove is provided on the outer ring of the end of the annular filter screen. The ring is installed in an annular groove, and a suction chamber is formed between the annular filter screen and the outer shell of the toothed disc crusher. A transition chamber communicating with the suction chamber is provided below the outer shell of the toothed disc crusher. One side of the transition chamber is connected to a negative pressure fan through a pipe, and the other end of the negative pressure fan is connected to a collection bin. A discharge port is provided at the bottom of the collection bin, and a valve is provided at the discharge port. A side cover is hinged to the opening of the outer shell of the toothed disc crusher. A feed port is provided in the middle of the side cover. An upwardly angled feed channel is provided on one side of the feed port, and a feed trough is provided at the upper end of the feed channel.

[0005] The bottom of the toothed disc crusher housing on the outer ring of the moving toothed disc is provided with a filter slot, and the annular filter is inserted into the filter slot.

[0006] The side cover has two rings of fixed crushing rods arranged in a circular array on the side of the toothed disc crusher shell, and the fixed crushing rods and the movable crushing rods are arranged alternately.

[0007] The outer ring of the fixed crushing rod of the side cover is provided with a layer of sealing rubber.
