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 feed placing mechanism, a sieving machine and a filling device for filling electric initiating explosive device granules. The feed placing mechanism comprises a working plate, the working plate is provided with an upper feed inlet and a lower feed inlet, and a feed placing plate is movably mounted between the upper feed inlet and the lower feed inlet; when the feed placing is performed, the feed placing plate moves away from the upper feed inlet and the lower feed inlet, and granules enter the lower feed inlet after passing through the upper feed inlet; when the feed placing stops, the feed moves to a position between the upper feed inlet and the lower feed inlet to stop feeding; a conductive pad is arranged on the contact position of the feed placing plate with the working plate. The sieving machine comprises a sieving plate, the sieving plate is provided with sieve meshes with the diameter of 10-15mm, and the number of the sieve meshes is 100-150 / m(2). The filling device comprises the feed placing mechanism, the sieving machine and a drive mechanism; the granules enter a filling mold after sequentially passing through the feed placing mechanism and the sieving machine, and the drive mechanism drive the feed placing mechanism and the sieving machine to perform vertical and rotational movement. The feed placing mechanism, the sieving machine and the filling device for filling electric initiating explosive device granules solve the problems of low work efficiency and poor safety performance of existing filling devices.

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 ...
