Description

Technical Field

[0001] This application relates to the technical field of material processing, and in particular to a rapid cooling kneading device. Background Technology

[0002] The quench kneading equipment is a key piece of equipment specifically designed for the production of high-melting-point, high-viscosity emulsifiers. Existing quench kneading equipment includes a housing, a quenching unit located above the housing, and a kneading unit located below the housing.

[0003] Specifically, the high-temperature molten material is fed into the crystallization cylinder of the quenching unit, and a refrigerant is rapidly introduced to induce rapid crystallization. The crystals that freeze and precipitate on the inner wall of the cylinder are scraped off by a rapidly rotating scraper. Inside the crystallization cylinder, the temperature of the liquid material has dropped below the melting point of the oil, forming a subcooled liquid. The subcooled liquid containing crystal nuclei enters the kneading unit, where the material in the cylinder is vigorously stirred and kneaded by the stirring blades, slowly forming crystals. Due to the heat of crystallization (approximately 50 kcal / kg) and the frictional heat generated by stirring, the temperature of the material exiting the kneading unit has risen again, making the crystals soft and forming specific crystal forms (such as α-crystals) and a fine texture.

[0004] One issue is that, because the inlet pipe is located outside the enclosure, it may be affected by external temperature during the transport of the subcooled liquid, which could then affect the formation of subsequent crystals and lead to unstable product quality. Therefore, further improvements are needed. Utility Model Content

[0005] To address the above problems, this application provides a rapid cooling kneading device.

[0006] This application provides a rapid cooling kneading device, which adopts the following technical solution:

[0007] A rapid cooling kneading device includes a housing, a rapid cooling unit disposed above the housing, and a kneading unit disposed below the housing. The rapid cooling unit and the kneading unit are connected by a connecting pipe, which is located outside the housing. An insulation component is provided outside the connecting pipe, and the insulation component includes an insulation sleeve covering the connecting pipe. An insulation cavity is left between the insulation sleeve and the connecting pipe.

[0008] By adopting the above technical solution, the quenching unit and the kneading unit are connected by a connecting pipe placed outside the box. An insulation component containing an insulation sleeve is installed outside the connecting pipe, and an insulation cavity is left between the insulation sleeve and the connecting pipe. This can reduce the influence of the external temperature on the subcooled liquid in the connecting pipe, ensure the temperature stability of the subcooled liquid, and thus facilitate the formation of specific crystal forms (such as α crystal form) and fine texture of the subsequent materials in the kneading unit.

[0009] Preferably, the insulation component further includes an input pipe and an output pipe passing through the insulation sleeve, wherein the input pipe is used to deliver the heat medium into the insulation cavity.

[0010] By adopting the above technical solution, since some crystals may remain in the connecting pipe during the transportation process, these crystals may adhere to the connecting pipe during the next transportation of subcooled liquid, which may cause blockage. In this regard, before use, the heat medium is introduced into the insulation cavity to melt the crystals located in the connecting pipe, thereby reducing the possibility of blockage caused by crystals remaining or adhering to the connecting pipe.

[0011] Preferably, the insulation cavity is arranged in a wavy or spiral shape along the length of the insulation sleeve.

[0012] By adopting the above technical solution, setting the insulation cavity in a wave-like or spiral shape can increase the time and contact area between the heat medium and the connecting pipe, better melt the crystals in the connecting pipe, reduce blockage, and also help maintain the stability of the subcooled liquid temperature.

[0013] Preferably, the thermal insulation sleeve includes a thermal insulation inner cylinder and a protective layer disposed outside the thermal insulation inner cylinder.

[0014] By adopting the above technical solution, the insulation sleeve adopts a heat-insulating inner cylinder and protective layer structure, which can enhance the heat preservation effect, further reduce heat loss, ensure the stability of the supercooled liquid during transportation, and help form a specific crystal form and fine texture.

[0015] Preferably, the connecting pipe includes a straight pipe and two first connecting pipes respectively disposed at both ends of the straight pipe. The insulation sleeve is a rigid insulation sleeve, which is sleeved on the outside of the straight pipe. At least one of the first connecting pipes is a bend, and a second connecting pipe is inserted through the bend. A control valve is disposed on the second connecting pipe, and a flushing pipe is detachably connected to the second connecting pipe.

[0016] By adopting the above technical solution, the connecting pipeline is equipped with a straight pipe and a first connecting pipe, and a rigid insulation sleeve is fitted over the straight pipe. Since the insulation sleeve is a rigid insulation sleeve and is fixedly connected to the straight pipe, it is not easy to process an insulation sleeve of the corresponding material for the first connecting pipe which is set in a bend. The second connecting pipe, which is equipped with a control valve and can be detachably connected to a flushing pipe, makes the structure of the connecting pipeline more reasonable. Therefore, in the case of blockage caused by the accumulation of crystals at the first connecting pipe, the control valve can be used to control the flow of water to clean the crystals remaining at the bend and reduce the possibility of blockage.

[0017] Preferably, the insulation component further includes a heat insulation layer disposed at the first connecting pipe.

[0018] By adopting the above technical solution and setting a heat insulation layer at the first connecting pipe, the heat preservation effect of the connecting pipe can be further enhanced.

[0019] Preferably, the connecting pipe includes a straight pipe and two first connecting pipes respectively disposed at both ends of the straight pipe, the heat insulation sleeve is sleeved outside the straight pipe, at least one of the first connecting pipes is a bend, and the heat insulation assembly also includes a flexible sleeve disposed at the bend, the flexible sleeve having a chamber for the retention of the heating medium.

[0020] By adopting the above technical solution, the connecting pipeline is divided into a straight pipe and a first connecting pipe. An insulating sleeve is installed over the straight pipe, with an insulating cavity to insulate the transported subcooled liquid, reducing the influence of external temperature and ensuring subsequent crystal formation. The insulating sleeve is typically a rigid sleeve, fixedly connected to the straight pipe, while it is difficult to manufacture a rigid insulating sleeve of the appropriate material for bent pipes. Therefore, a flexible sleeve with a heat-retaining medium is installed at the first connecting pipe. This not only insulates the subcooled liquid inside the first connecting pipe but also allows for the introduction of a heat-retaining medium before use to melt any crystals inside the first connecting pipe, reducing the risk of blockage caused by crystal retention.

[0021] Preferably, the flexible sleeve includes a flexible plate that can be bent into a cylindrical shape and a connector for detachably connecting the two sides of the flexible plate to cover the first connecting pipe. The flexible sleeve is provided with a heat medium inlet and an outlet.

[0022] By adopting the above technical solution, the flexible sleeve includes a flexible plate that can be bent into a cylindrical shape and connecting parts, which are convenient for disassembly and installation. It can cover the first connecting pipe. The hot medium inlet and outlet provided on it can allow the hot medium to flow into and out of the chamber inside the flexible sleeve, further ensuring that the transportation of the subcooled liquid in the first connecting pipe is not affected by the external temperature and preventing the blockage of the first connecting pipe by crystals.

[0023] In summary, this application has the following beneficial effects:

[0024] Insulation components are installed outside the connecting pipes to reduce the impact of external temperature when transporting subcooled liquid, ensuring the normal formation of subsequent crystals and improving product quality stability. Before use, the heat medium is introduced into the insulation cavity to melt the crystals located in the connecting pipes, reducing the possibility of pipe blockage and ensuring continuous production. This reduces equipment maintenance costs and downtime caused by pipe blockage, and improves equipment lifespan and production efficiency. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0032] This application discloses a rapid cooling kneading device.

[0033] Example 1:

[0034] A rapid cooling kneading device, as described in the following figure Figure 1 The system includes a housing 1, a quenching unit 11 located above the housing 1, and a kneading unit located below the housing 1. It should be noted that the quenching unit 11 and the kneading unit 12 are existing technologies and will not be described in detail here. The quenching unit 11 and the kneading unit 12 are connected by a connecting pipe 2, which is located outside the housing 1. An insulation component 3 is installed outside the connecting pipe 2. This arrangement reduces the impact of external temperature on the transported subcooled liquid, thereby reducing subsequent crystal formation.

[0035] Reference Figure 1 , Figure 2 The connecting pipe 2 includes a straight pipe 21 and two first connecting pipes 22 respectively disposed at both ends of the straight pipe 21. The straight pipe 21 is generally straight and can be made of stainless steel, which is corrosion-resistant and has high strength, or carbon steel, which is less expensive. The first connecting pipes 22 are usually bent or tee pipes, with one of the first connecting pipes 22 being bent. The first connecting pipes 22 and the straight pipe 21 can be connected by welding or flange to ensure a tight connection. In this embodiment, the first connecting pipes 22 and the straight pipe 21 are welded together.

[0036] The insulation component 3 specifically includes an insulation sleeve 31 covering the connecting pipe 2, an input pipe 32 and an output pipe 33 passing through the insulation sleeve 31, a control pump 34 connected to the input pipe 32, and an insulation layer 35. The insulation sleeve 31 is coaxially sleeved on the outside of the straight pipe 21 and fixedly connected to the straight pipe 21. An insulation cavity 4 is left between the insulation sleeve 31 and the straight pipe 21. Specifically, the insulation sleeve 31 includes an insulation inner cylinder 311 and a protective layer 312 disposed outside the insulation inner cylinder 311. The protective layer 312 is made of metal to make the insulation sleeve 31 have greater overall hardness and rigidity, making it a rigid insulation sleeve 31.

[0037] Furthermore, the insulation cavity 4 can be arranged in a wavy or spiral shape along the length of the insulation sleeve 31, which can increase the flow path and residence time of the heat medium in the insulation cavity 4 and improve the insulation effect.

[0038] The input pipe 32 is used to transport the heat medium into the insulation cavity 4, while the output pipe 33 outputs the heat medium after heat exchange. In this embodiment, the heat medium can be hot water or hot oil, depending on the requirements. The insulation cavity 4 between the insulation sleeves 31 on two adjacent connecting pipes 2 is connected by the delivery pipe 36. It should be noted that the input pipe 32, output pipe 33, and delivery pipe 36 are all provided with a heat insulation layer 35 for heat insulation treatment to reduce the heat loss of the transported heat medium.

[0039] The insulation layer 35 can also be made of insulation materials such as glass wool or rock wool to prevent heat loss at the bend and avoid crystals from accumulating at the bend.

[0040] The implementation principle of the rapid cooling kneading device in this application embodiment is as follows: an insulation component 3 is installed outside the connecting pipe 2 to reduce the influence of external temperature when transporting the supercooled liquid, ensuring the normal formation of subsequent crystal forms and improving product quality stability; before use, the heat medium is introduced into the insulation cavity 4, which reduces the risk of pipe blockage, extends the service life of the equipment, improves production efficiency, and reduces maintenance costs, making a significant improvement over the prior art.

[0041] Example 2:

[0042] Reference Figure 3The difference from Embodiment 1 is that a second connecting pipe 5 is inserted through the first connecting pipe 22, and a control valve 51 is installed on the second connecting pipe 5. A flushing pipe 52 is detachably connected to the second connecting pipe 5. The second connecting pipe 5 is generally made of metal, such as stainless steel, which has high strength. The control valve 51 can be a ball valve or a butterfly valve for easy control of fluid flow. The flushing pipe 52 can be a rubber tube or a corrugated pipe, which can be threaded onto the second connecting pipe 5 with a nut. When it is necessary to clean the bend, the control valve 51 is opened, and cleaning fluid is injected into the bend through the flushing pipe 52 to flush away any retained crystals. It can also be used for sampling.

[0043] Example 3:

[0044] Reference Figure 4 , Figure 5 The difference from Embodiment 1 is that the heat preservation component 3 also includes a flexible sleeve 6 disposed at the first connecting pipe 22, and the flexible sleeve 6 has a chamber 61 for retaining the heating medium.

[0045] The flexible sleeve 6 includes a flexible plate 62 that can be bent into a cylindrical shape and a connector 63 for detachably connecting the two sides of the flexible plate 62 to cover the first connecting pipe 22. The flexible plate 62 is hollow, forming a chamber 61. The flexible sleeve 6 has a heat medium inlet 64 and an outlet 65, which are respectively connected to an input pipe 32 and an output pipe 33. Since there are multiple connecting pipes 2, a delivery pipe 36 is provided between two flexible sleeves 6. In this embodiment, the flexible plate 62 can be made of silicone, which is soft and has a certain degree of flexibility, and can fit the shape of the bent pipe well. The connector 63 can be Velcro or a snap fastener for easy disassembly and installation. The heat medium enters the chamber 61 of the flexible sleeve 6 from the heat medium inlet 64 and then flows out from the heat medium outlet 65.

[0046] In this embodiment, a flexible sleeve 6 replaces the insulation layer 35. Since it also carries a heat medium, it can heat the bend more evenly, improving the insulation effect at the bend. The detachable design of the flexible sleeve 6 facilitates cleaning and maintenance. This design further reduces the possibility of crystal buildup at the bend, decreasing the risk of pipe blockage, while also improving the applicability and flexibility of the insulation component 3.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
