Embodiment 1

[0033] see figure 1 , the discharge mechanism of this embodiment includes an upper bracket 111 with an upper feeding hole 12, a lower bracket 112 with a lower feeding hole 13, an opening and closing cylinder 15, a cylinder piston 151, a connecting piece 16, and a discharging plate 14 And conductive sealing ring 17.

[0034] The upper bracket 111 and the lower bracket 112 are closely matched to form the working plate 11. The diameter of the upper feed hole 111 is smaller than the diameter of the lower feed hole 112 to prevent the material from being blocked during the feeding process. The opening and closing cylinder 15 is installed on the upper bracket 111. The cylinder piston 151 is fixedly connected to the connection piece 16, and the connection piece 16 is connected to the discharge plate 14. The discharge plate 14 passes between the conductive sealing gaskets 17, and the discharge insertion plate 14 is closely matched with the conductive sealing gasket 17, so that the elec...

Embodiment 2

[0037] see figure 2 , the sifter of this embodiment includes a circular sieve cylinder, the inner diameter of which is 900mm, and the inner diameter is 700mm. Two sieve plates are installed up and down in the sieve cylinder, and a plurality of sieve holes 22 are evenly distributed on each sieve plate 22 . The upper and lower distance between the two sieve plates is 30cm, the diameter of the sieve holes is 15mm, and the number of sieve holes per unit area is 100 holes / cm 2 .

[0038] When the propellant cast particles flow into the sieve, the cast particles flow through the sieve plate and the sieve holes of the sieve plate in turn, and then flow into the mold, so that the flow speed of the cast particles can be controlled to increase the filling density of the propellant cast particles in the mold the goal of.

Embodiment 3

[0040] see figure 2 , the sifter of this embodiment includes a circular sieve cylinder, the inner diameter of which is 900mm, and the inner diameter is 800mm. A sieve plate is installed up and down in the sieve cylinder, the diameter of the sieve hole is 10mm, and the number of sieve holes per unit area is 150 holes / cm 2 .

[0041] When the propellant cast particles flow into the sieve, the cast particles flow through the sieve plate and the sieve holes of the sieve plate in turn, and then flow into the mold, so that the flow speed of the cast particles can be controlled to increase the filling density of the propellant cast particles in the mold the goal of.

[0042] Example 3:

[0043] The processing capacity of the propellant casting particle filling equipment of this embodiment is 100-130 Kg / h.

[0044] refer to image 3 , the propellant casting particle filling equipment of this embodiment includes a barrel 3, the discharge mechanism 1 in embodiment 1, the sieve d...

Abstract

The invention relates to a discharging mechanism, a sieving device and a loading device used for loading granular materials of pyrotechnic products. The discharging mechanism involved includes a working plate, which is provided with upper and lower feed holes, and a discharging plate is movable between the upper and lower feeding holes; when discharging, the discharging plate is separated from the upper and lower feeding holes. Feed hole, the granular material enters the lower feed hole through the upper feed hole; when the discharge is stopped, the discharge plate moves to the upper and lower feed holes to block the feed; the position where the discharge plate contacts the working plate is equipped with a conductive pad. The sieve involved includes a sieve plate, and the sieve plate is provided with sieve holes with a diameter of 10-15mm, and the number of sieve holes is 100-150 / m 2 . The filling equipment involved includes the above-mentioned discharge mechanism, screener and drive mechanism. The granular material enters the filling mold through the discharge mechanism and screener in turn, and the drive mechanism drives the discharge mechanism and screener to move up and down and rotate. . The invention solves the problems of low work efficiency and poor safety performance existing in the existing filling equipment.

Description

technical field [0001] The present invention relates to discharging, screening and filling technology of pyrotechnics granular material, in particular to a discharging mechanism for loading pyrotechnics granular material, and also to a sieving device for loading pyrotechnics granular material, and further It relates to the equipment for charging the granular material of pyrotechnics. Background technique [0002] In the production of granulated and cast pyrotechnic pellets (such as nitrocellulose balls, propellant cast particles), the filling of cast pellets has always been the face-to-face manual filling method of human / pyrotechnic pellet molding molds. This manual filling method has the following disadvantages: [0003] (1) Manual weighing and filling of casting particles, the production labor intensity is high; [0004] (2) The flow rate of the cast particles poured into the mold is artificially controlled by experience, and the packing density of the cast particles in ...
