The invention provides an integral suction filtration and distribution device for manufacturing initiating explosives. The integral device comprises a suction filtration part, a distribution part and a controller, wherein the suction filtration part comprises a lifting air cylinder, a suction filtration tank body, a suction filtration hopper, filter cloth, a lifting device and the like; the distribution part comprises a discharging hopper, a receiving plate, a rotary plate, a weighing device and the like. According to the integral device, suction filtration and distribution processes are controlled by virtue of the controller and can be automatically carried out; the suction filtration hopper, the discharging hopper, the filter cloth and the lifting part cooperate with each other, so that the initiating explosives after suction filtration can quickly enter the discharging hopper and the working efficiency is improved; the tail end of the discharging hopper is connected with the lifting air cylinder, and the lifting air cylinder is connected with a vibrator, so that a certain slope can be formed by taking a discharging hole of the discharging hopper as the lowest end after the initiating explosives are transferred to the discharging hopper and the initiating explosives can be further transferred conveniently; the rotary plate, the weighing device, a rotary indexing device and the controller are combined, so that the initiating explosives can be distributed according to the set weight, the operation is convenient, and the working efficiency is greatly improved.
