Description

Technical Field

[0001] This utility model belongs to the field of emulsion explosive production technology, specifically relating to an emulsion filtration device for emulsion explosive production. Background Technology

[0002] Emulsion explosives are characterized by high density, high detonation velocity, high saturation, good water resistance, small critical diameter, and good initiation sensitivity, exhibiting detonator sensitivity even in small-diameter applications. There are open-pit emulsion explosives for open-pit mines, rock-type emulsion explosives for blasting medium-hard rock, permissible emulsion explosives for underground coal mines, and small-diameter, low-detonation-velocity emulsion explosives for smooth blasting. Emulsion explosives are now widely used in various civilian blasting operations, demonstrating their superiority in blasting environments with water or moisture. However, emulsion filtration devices are prone to clogging during use, and impurities filtered from the emulsion are difficult to remove, making subsequent cleaning challenging.

[0003] Patent application number 202122313182.6 discloses an emulsion filtration device for the production of emulsion explosives, including a cylinder and a support. An injection pipe and a flushing pipe are respectively provided on one side of the cylinder. An outlet pipe is provided at the bottom of the cylinder. A bucket cover is provided at the top of the cylinder. A water inlet pipe is provided at the top of the bucket cover. A double-layer filter bucket is provided inside the cylinder. The first filter screen is provided with several fixing blocks. A pushing device is provided inside each fixing block.

[0004] The above technical solution uses an electric auger structure to transport the filtered emulsion explosive. However, due to the viscosity of the emulsion explosive, it only relies on its own gravity to penetrate through the filter plate after being input through the injection pipe, resulting in low filtration efficiency. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an emulsion filtration device for the production of emulsion explosives. This emulsion filtration device aims to solve the technical problem of low filtration efficiency of emulsion explosives due to their viscosity. After being introduced through the injection pipe, the emulsion explosives rely solely on their own gravity to penetrate through the filter plate.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides an emulsion filtration device for the production of emulsion explosives. The emulsion filtration device for the production of emulsion explosives includes an emulsion explosive filter tank and a top cover threadedly inserted into the top of the emulsion explosive filter tank. A hollow tube is fixed at the center of the bottom end face of the top cover, and a filter plate with an annular structure is detachably installed at the bottom end of the top cover. An input pipe located inside the filter plate is fixed on the top cover. A folded air bag is sleeved on the hollow tube, and an air supply hole communicating with the folded air bag is opened on the inner wall of the hollow tube.

[0009] When using this technical solution, a hollow tube is fixed at the bottom of the top cover. The emulsion explosive is delivered to the filter plate through the input pipe, and air is delivered to the folded airbag through the air outlet on the hollow tube via the air supply pipe. The folded airbag, which has a ring structure, compresses the emulsion explosive to penetrate the filter plate during expansion. After filtration, the emulsion explosive is discharged from the output pipe. This facilitates the compression of the emulsion explosive to penetrate the filter plate from the center of the emulsion explosive filter tank, improving the filtration efficiency of viscous emulsion explosive. A fastening ring is fixed at the bottom of the top cover, and the filter plate is threaded into the fastening ring to keep it fixed. The top cover is installed in the emulsion explosive filter tank so that the bottom end of the filter plate fits into the arc groove. After filtration, the sealing plug is unscrewed by the third handle, and the top cover and filter plate are disassembled and rinsed. During the cleaning process, the filter residue is discharged from the drain pipe, improving the convenience of cleaning and draining the emulsion explosive filter tank.

[0010] Preferably, a first handle and a second handle are fixed on both sides of the top surface of the top cover, and the top of the hollow tube passes through the top cover and is tightly connected to a gas supply pipe.

[0011] Furthermore, a transparent viewing window is embedded in the side wall of the emulsion explosive filter canister, and an output pipe is installed at the bottom end of the side wall of the emulsion explosive filter canister, wherein an arc-shaped groove is formed in the bottom wall of the emulsion explosive filter canister.

[0012] Furthermore, a fastening ring is fixed to the bottom end of the top cover, and a solenoid valve is installed on the input pipe.

[0013] Furthermore, the top end of the filter plate is threaded into the fastening ring, and the bottom end of the filter plate is fitted into the arc-shaped groove.

[0014] Furthermore, grooves are provided on both sides of the outer wall of the hollow tube, the folded airbag has an annular structure, and the two sides of the protruding inner wall of the folded airbag are fixed to the grooves.

[0015] Furthermore, a drain pipe is installed at the bottom of the emulsion explosive filter canister, and a sealing plug is threaded into the bottom of the drain pipe. A third handle is fixedly installed at the bottom of the sealing plug.
