Description

A composite wax production line Technical Field

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

[0002] Currently, composite wax, as a raw material for emulsion explosives, requires liquefying large solid wax raw materials, mixing them with other substances, reacting them, and then solidifying them into small granules for packaging, storage, and transportation. Currently, melting is mostly done in wax melting pools, which proceed slowly from the outside in, resulting in low efficiency. A pool of wax raw materials takes a long time to completely melt. After melting, the outlet of the wax melting pool needs to be opened to output the molten wax raw material, leading to poor production continuity and making it unsuitable for continuous production needs. The molten wax needs to be uniformly mixed with other additives. When the amount of additives is large, existing mixing tanks need to be connected to multiple additive pipes, resulting in poor overall integrity. The wax liquid has high viscosity, and existing stirring blades have poor mixing effect. 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 the high viscosity of the composite wax raw material, some wax tends to solidify and precipitate when stored in ordinary storage tanks, affecting subsequent production stages.

[0050] A spiral guide plate is provided inside the heating jacket 53; the heating jacket 53 is covered with a heat insulation layer 59.

[0052] A wax raw material screw conveyor 61 is installed 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 liquid outlet of the storage tank 51.

[0053] Example 1: Wax raw material is added into the crushing shell 2 through wax raw material inlet 4. The heat-conducting stirring shaft 1 rotates, driving the crushing spiral blades 6 to crush the wax raw material blocks. Through the synergistic action of the transverse crushing rod 10 and crushing teeth 12, large pieces of wax raw material are crushed into smaller pieces for easy melting. The crushed raw material enters the wax melting shell 3 under the drive of the crushing spiral blades 6. The heat-conducting oil outlet pipe and the heat-conducting oil return pipe are respectively connected to the corresponding rotary joints 9. The heat-conducting oil flows into the medium flow chamber 8 at one end of the heat-conducting stirring shaft 1, passes through the heat-conducting spiral blades 7, and flows out from the medium flow chamber 8 at the other end of the heat-conducting stirring shaft 1, heating the wax raw material from the inside. At the same time, the heat-conducting oil is introduced into the heating jacket 11 to heat the wax raw material from the outside, accelerating the melting of the wax raw material. The melted wax raw material is discharged from the wax melting outlet 5 under the drive of the heat-conducting spiral blades 7, filtered in the filter cylinder, and then transported to the next station.

[0054] The diameter of the crushing shell 2 is larger than the diameter of the wax melting shell 3. A certain amount of space needs to be left during crushing to avoid the material being stuck by large pieces of wax raw material during feeding.

[0055] The rotary joint 9 can continuously supply heat transfer oil while the heat-conducting stirring shaft 1 is rotating.

[0056] 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 their corresponding branch feed pipes 32, and then flow into the mixing tank 21 along the feed bend 30. The electric motor drives the mixing shaft 22 to rotate, stirring the wax raw material at the bottom with frame-type stirring blades 23, and the wax raw material in the middle and upper parts with a set of circulating stirring blades 24. Since the raw material at the bottom has poorer fluidity, a contour scraper 35 is used to remove the raw material adhering to the inner wall of the bottom of the mixing tank 21, making the raw material and ingredients more evenly mixed. 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 two types of blades work together for better mixing. Steam or heat transfer oil is introduced into the insulation jacket 33 to heat the raw material in the mixing tank 21 and prevent the wax from solidifying. After mixing is complete, the electric actuator drives the discharge valve 34 to open, discharging the composite wax.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] The vertical stirring blade 56 plays an auxiliary stirring role, enhancing the stirring of the composite wax raw material in the middle.
