Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite wax production equipment, specifically to a composite wax melting and stirring 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. 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 material takes a long time to completely melt. After melting, the outlet of the wax melting pool needs to be opened to remove the molten wax raw material, leading to poor production continuity and making it unsuitable for continuous production needs in engineering projects. 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 provide poor mixing effect. Utility Model Content

[0037] The wax melting outlet 5 is connected to the feed inlet of the mixing tank 21 via a screw conveyor.
[0038] The heat-conducting stirring shaft 1 is mounted on the wax melting machine frame via bearings and bearing housings.
[0039] The heat-conducting stirring shaft 1 has media flow chambers 8 at both ends, and rotary joints 9 connected to the media flow chambers 8 at both ends. The heat-conducting spiral blades 7 are hollow spiral blades and are connected to the media flow chambers 8. The heat-conducting medium flows into the media 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 media flow chamber 8 at the other end of the heat-conducting stirring shaft 1. Multiple sets of crushing teeth 12 are provided on the inner wall of the crushing shell 2. A transverse crushing rod 10 is provided on the spiral blade of the crushing spiral blade 6.
[0040] The outer wall of the wax melting shell 3 is covered with a heating jacket 11; both the crushing shell 2 and the wax melting shell 3 are hollow cylindrical shells.
[0041] The diameter of the broken shell 2 is larger than the diameter of the melted shell 3.
[0042] The motor is equipped with a drive sprocket, and the heat-conducting stirring shaft 1 is equipped with a driven sprocket. The motor drives the heat-conducting stirring shaft 1 to rotate through a chain drive mechanism.
[0043] 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.
[0044] 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.
[0045] The outer wall of the mixing tank 21 is covered with an insulation jacket 33.

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.
[0047] 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.
[0048] 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.
[0049] The rotary joint 9 can continuously supply heat transfer oil while the heat-conducting stirring shaft 1 is rotating.
[0050] 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.
