Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a high-viscosity composite wax blending stirring kettle. Background Art

[0002] High viscosity composite wax is a composite material made of paraffin wax, microcrystalline wax, resin, elastomer, etc. in a certain proportion and sequence. The product has high added value and is mainly used in special materials, energy storage materials, high viscosity sealing, building waterproofing and other fields. Conventional wax products have a low kinematic viscosity at 100℃, usually at 15mm 2 / s, while high-viscosity composite wax is added with a large amount of polymer materials due to its application in special scenarios, and its kinematic viscosity at 140℃ usually reaches 15mm 2 / s or more. High-viscosity composite wax needs to be heated or stirred at a constant temperature during production. Uneven stirring or local overheating can easily produce charred substances, which can easily reduce the performance of polyethylene wax and cause economic losses. In addition, when producing high-viscosity composite wax, paraffin wax and microcrystalline wax products need to be added first and completely melted before adding various polymer additives. Since polymer additives are usually in a solid-like state, they will float on the surface of the liquid in the kettle after being added. Conventional stirring kettles with ordinary paddles have poor stirring effects and insufficient stirring intensity, making it difficult to press the additives into the liquid wax in time. The additives cannot be melted for a long time, which ultimately leads to the product often exceeding the color standard, affecting product quality.

[0003] To address the shortcomings of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a composite wax hot melt stirring device [CN202310580951.X], which includes a processing cylinder, a stirring motor disposed at the top of the processing cylinder, a stirring rod and a frame-type stirring frame disposed below the stirring motor, an inner wall disposed outside the frame-type stirring frame, a heating layer disposed within the inner wall and the processing cylinder, a spiral heating tube disposed within the heating layer, a fan device connected to one side of the upper end of the heating layer, the fan device connected to a wax liquid input block via a heat conducting tube, an inclined plate disposed within the inner cavity of the wax liquid input block, a multi-nozzle annular plate disposed near the outer periphery of the stirring rod, a connecting block disposed at the liquid inlet end of the multi-nozzle annular plate, a wax liquid delivery pipe and a pump body disposed at the lower end of the connecting block, a discharge cylinder connected to the mounting surface of the pump body, and a linear screw and a linear guide rod disposed on both sides of the outer periphery of the discharge cylinder.

[0004] The above solution solves to a certain extent the problem in the prior art that high-viscosity composite wax is easily stirred due to uneven stirring or local overheating to produce charred substances, thereby reducing the performance of polyethylene wax and causing economic losses. However, this solution still has many shortcomings, such as: poor stirring effect, insufficient stirring intensity, difficulty in pressing the additives into the liquid wax in time, and the additives cannot be melted for a long time, which ultimately leads to the product often exceeding the color standard and affecting product quality.

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] like Figure 1-7 As shown, a high-viscosity composite wax blending stirring kettle includes a stirring kettle body 1, a material receiving component 2 is provided at the upper end of the stirring kettle body 1, a spiral stirring device 4 located on the inner side of the stirring kettle body 1 is connected to the upper end of the stirring kettle body 1 through a rotating drive mechanism 3, and a spoiler structure 5 is provided on the inner wall of the stirring kettle body 1, and a heating and discharging component 6 is provided at the lower end of the stirring kettle body 1.

[0027] Among them, the rotation drive mechanism 3 includes a rotation lifting motor 31 arranged at the upper end of the stirring tank body 1, the rotation lifting motor 31 is positioned by a motor seat 32, and the output end of the rotation lifting motor 31 is connected to a rotating threaded linkage shaft 33 arranged in the stirring tank body 1.

[0028] The motor base 32 drives the rotary threaded linkage shaft 33 to rotate, and the spiral stirring device 4 is passively lifted and lowered.

[0029] Obviously, the spiral stirring device 4 includes a lifting sleeve 41 threadedly connected to the rotating threaded linkage shaft 33, and a spiral stirring paddle 42 is provided on the shaft of the lifting sleeve 41, and the upper and lower ends of the spiral stirring paddle 42 are respectively provided with symmetrical spiral stirring structures 43.

[0030] The arrangement of the spiral-ribbon stirring blade 42 enables the material to form axial flow stirring, that is, the material spirally rises and then converges through the central cavity to form an up-and-down convection circulation, while preventing the material from adhering.

[0031] Furthermore, the spiral stirring structure 43 and the lifting sleeve 41 are spaced apart from each other by a separation spring 44 .

[0032] This can prevent the spiral stirring structure 43 and the lifting sleeve 41 from colliding and being damaged with each other, thereby improving stirring safety.

[0033] Furthermore, the spiral stirring structure 43 includes a threaded lifting sleeve 431, which is threadedly connected to the rotating threaded linkage shaft 33. The threaded lifting sleeve 431 is circumferentially provided with a plurality of inclined spiral blades 432, and one end of the spiral blade 432 connected to the threaded lifting sleeve 431 has a rotating connecting rod 433, and the rotating connecting rod 433 is provided with an annular rotating connecting portion 434, and the outer wall of the threaded lifting sleeve 431 is provided with an annular rotating connecting groove 435 for the annular rotating connecting portion 434 to be inserted.

[0034] When the rotating threaded linkage shaft 33 rotates, the spiral stirring structure 43 rotates synchronously and rises and falls, thereby quickly pressing the floating additives into the bottom of the stirring tank body 1. In addition, the spiral stirring structure 43 adopts the axial flow spiral blade 432 design, which has very low shear force and large turbulent diffusion performance, and can quickly press the solid suspension into the mixture to form fusion, thereby improving the stirring effect.

[0035] Specifically, the spoiler structure 5 includes a spoiler body 51 arranged on the circumferential inner wall of the stirring tank body 1 , a guide inclined plate 52 is connected to the spoiler body 51 , and a plurality of drainage holes 53 are provided on the spoiler body 51 .

[0036] The provision of the guide inclined plate 52 can prevent the material from always making circular motion during stirring, thereby improving the stirring effect. In addition, the combination with the drainage hole 53 can enhance the disturbance effect on the material, change the inertial flow state, and thus improve the stirring effect.

[0037] More specifically, the heating and discharging assembly 6 includes a bell-shaped cover body 61 arranged at the bottom of the stirring kettle body 1, and the bell-shaped cover body 61 is circumferentially provided with a filter screen 62, and the inner side of the bell-shaped cover body 61 is provided with a rotating positioning base 63 for connecting the bottom of the rotating threaded linkage shaft 33, and the bottom of the stirring kettle body 1 is provided with a discharge port 64 that is interconnected with the inner side of the bell-shaped cover body 61.

[0038] The bell-shaped housing 61 is a frame, and the filter screen 62 is used for filtering the material during discharge to improve the purity.

[0039] In detail, a plurality of stacked heating water pipes 65 are provided on the outer circumference of the bell-shaped housing 61 . The diameter of the heating water pipes 65 gradually increases from top to bottom and the upper ends are open.

[0040] Preferably, the material receiving assembly 2 includes a material receiving port 21 , the material receiving port 21 is connected to a material receiving funnel 22 , and an inclined feed dispersion baffle 23 is provided on the inner wall of the stirring kettle and located on one side of the discharge port of the material receiving port 21 .

[0041] In addition, the material receiving port 21 is connected to a feeding funnel 24 , and one end of the feeding funnel 24 has a feeding opening 241 .

[0042] To sum up, the principle of this embodiment is that the material enters the receiving port 21 through the receiving funnel 22 and enters the interior of the stirring tank body 1 through the feed dispersion baffle 23, the rotating lifting motor 31 drives the rotating threaded linkage shaft 33 to rotate, and the material is stirred in an axial flow through the spiral stirring paddle 42, that is, the material spirally rises and then converges through the central concave hole to form an upper and lower convection circulation, and the spiral stirring structure 43 rotates synchronously and performs a lifting action, so that the floating polymer powder additive is quickly pressed into the bottom of the stirring tank body 1. Secondly, during the stirring process, the spoiler structure 5 is used to prevent the material from always making a circular motion during stirring, and cooperates with the drainage hole 53 to enhance the disturbance effect on the material, change the inertial flow state, and thus improve the stirring effect.
