Description

Technical Field

[0001] This utility model relates to the field of composite wax production equipment, specifically to a composite wax stirring and storage system. Background Technology

[0002] Currently, composite wax, as a raw material for emulsion explosives, requires liquefying large blocks of solid wax raw material, mixing it with other substances, reacting it, and then solidifying it into small granules for packaging, storage, and transportation. The molten wax needs to be uniformly mixed with other additives. When the amount of additives is large, existing mixing tanks require connecting multiple additive pipelines, resulting in poor overall integrity. Furthermore, the high viscosity of the wax molten material makes the existing stirring blades ineffective. On composite wax production lines, to improve production continuity, the molten composite wax raw material is stored in dedicated storage tanks for rapid output during production. Due to its high viscosity, the composite wax raw material is prone to partial solidification and sedimentation when stored in ordinary tanks, affecting subsequent production stages.

[0033] The storage tank includes a tank body 51 and an anti-caking agitator 52.

[0034] The top of the storage tank 51 is provided with a wax inlet, the bottom of the storage tank 51 is provided with a wax outlet, the outer wall of the storage tank 51 is covered with a heating jacket 53, and the stirring shaft of the anti-caking agitator 52 is provided with an anchor-type stirring paddle 54 and a frame-type stirring paddle 55.

[0035] The discharge port of the mixing tank 21 is connected to the wax inlet of the storage tank 51 via a screw conveyor.

[0036] The frame-type stirring blade 23 is composed of a U-shaped blade 26 and a horizontal blade 27, with the horizontal blade 27 installed inside the U-shaped blade 26; a contour scraper 35 is provided on the U-shaped blade 26, and the contour scraper 35 is fixed to the U-shaped blade 26 by bolts; the circulating stirring blade 24 is composed of a pair of diamond blades 28, with a U-shaped fork 29 provided at the end of the diamond blade 28.

[0037] The batching pipe 25 consists of a feed bend 30 and a branch feed block 31. The branch feed block 31 has a feed channel in the middle. A set of branch feed pipes 32 connected to the feed channel are respectively provided on both sides of the branch feed block 31. The feed bend 30 is installed on the top of the mixing tank 21.

[0038] The outer wall of the mixing tank 21 is covered with an insulation jacket 33.

[0039] A discharge valve 34 is provided on the discharge port of the mixing tank 21; a tank support is provided at the bottom of the mixing tank 21, and an actuator mounting bracket is provided on the tank support. An electric actuator is connected to the valve stem of the discharge valve 34 and the electric actuator is fixed on the actuator mounting bracket.

[0040] The frame-type agitator 55 is located above the anchor-type agitator 54; a pair of vertical agitator blades 56 are symmetrically distributed on the blades of the anchor-type agitator 54; the frame-type agitator 55 is composed of a U-shaped lower agitator blade 57 and an inverted U-shaped upper agitator blade 58.

[0041] A spiral guide plate is installed inside the heating jacket 53.

[0042] The heating jacket 53 is covered with an insulation layer 59.

[0043] A set of lugs is provided on the pipe wall of the storage tank 51, and the storage tank 51 is installed on the tank support through the lugs; an inspection port 60 is provided on the top of the storage tank 51, and a sealing cover is provided on the inspection port 60.

[0044] A discharge valve is provided on the wax discharge port of the storage tank 51; a wax raw material screw conveyor 61 is provided on the tank support of the storage tank 51, and the inlet of the wax raw material screw conveyor 61 is connected to the wax discharge port of the storage tank 51.

[0045] Example 1: Melted wax raw material is added through the feed inlet at the top of the mixing tank 21. Various ingredients are added to their respective feed blocks 31 through corresponding branch feed pipes 32, and then flow into the mixing tank 21 along the feed bend 30. The electric motor drives the stirring shaft 22 to rotate, and the frame-type stirring blades 23 agitate the wax raw material at the bottom. A set of circulating stirring blades 24 agitates the wax raw material in the middle and upper parts. Since the raw material at the bottom has poorer fluidity, a contour scraper 35 removes the material adhering to the inner wall of the bottom of the mixing tank 21, ensuring more uniform mixing of the raw material and ingredients. The circulating stirring blades 24 consist of a pair of diamond-shaped blades 28, with the root and tip of the blades propelling the fluid in opposite directions to promote axial circulation. The combination of the two types of blades provides better mixing. Steam or heat transfer oil is introduced into the insulation jacket 33 to heat the raw material in the mixing tank 21, preventing the wax from solidifying. After mixing is complete, the electric actuator opens the discharge valve 34 to discharge the composite wax.

[0046] An electric motor is connected to the top of the stirring shaft of the anti-caking agitator 52, which drives the anti-caking agitator 52 to operate.

[0047] The mixed composite wax raw material is injected through the wax inlet at the top of the storage tank 51. During storage, the composite wax raw material is slowly stirred by an anchor-type agitator 54 and a frame-type agitator 55 driven by an electric motor. The composite wax raw material at the bottom is stirred by the anchor-type agitator 54, which has a small distance between itself and the bottom surface of the storage tank 51, thus preventing the composite wax raw material from solidifying on the inner wall of the storage tank 51. The frame-type agitator 55 stirs the composite wax raw material at the top, preventing solidification. When it is necessary to discharge the composite wax raw material, the discharge valve is opened, and the composite wax raw material is continuously discharged through the wax raw material screw conveyor 61.

[0048] A heat transfer medium, such as heat transfer oil or steam, is introduced into the heating jacket 53 to periodically heat the storage tank 51, preventing the composite wax raw material from solidifying due to low temperatures. The insulation layer 59 is made of asbestos fiber material.

[0049] The vertical stirring blade 56 plays an auxiliary stirring role, enhancing the stirring of the composite wax raw material in the middle.
