Description

Technical Field

[0001] This utility model belongs to the field of oil extraction technology, specifically relating to an internal and external heating smelting device. Background Technology

[0002] With the continuous development of the livestock industry, a large amount of slaughter waste, a potentially valuable renewable resource, has been generated. For example, fatty tissue obtained from animal slaughter or cutting contains various fatty acids, which can be further processed to enhance their added value. Melting equipment is a common device for extracting animal fats. The common heating method involves installing heating packs or layers outside the melting equipment. This method only heats the material inside the tank from the outside, resulting in limited heat transfer efficiency and low melting efficiency. Therefore, improvements to existing melting equipment are necessary. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides an internal and external heating smelting device to improve smelting efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An internally and externally heated smelting device includes a base and a horizontal tank. The tank is fixedly installed on the base. The top of the tank is provided with a material inlet, a vacuum hole, and a manhole. A rotating shaft is rotatably connected inside the tank and arranged along the axial direction of the tank. Several stirring blades are arranged on the outer periphery of the rotating shaft. A drive device for driving the rotating shaft to rotate is provided at one end of the tank. A material outlet is provided at the lower part of the other end of the tank. A heating layer is surrounded in the middle and lower part of the tank. A heat inlet and a heat outlet are provided on the heating layer. A heat conduction channel is opened axially inside the rotating shaft. A rotary joint is installed at the end of the rotating shaft away from the drive device. The rotary joint is used to connect to an external heating device.

[0006] Optionally, the heating layer includes a first half-heating layer and a second half-heating layer, and the first half-heating layer and the second half-heating layer are respectively provided with a set of heat inlets and heat outlets.

[0007] Optionally, the heating layer includes multiple flow guide layers parallel to the rotation axis, with adjacent flow guide layers interconnected.

[0008] Optionally, each flow guide layer is provided with a connecting hole, and between adjacent flow guide layers, the connecting hole of one flow guide layer is close to one end of the tank, and the connecting hole of the other flow guide layer is close to the other end of the tank.

[0009] Optionally, a viewing window is provided on the end side wall of the tank.

[0010] Optionally, the drive device includes a motor, a transmission belt, and a reducer.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects:

[0012] This invention features simultaneous internal and external heating. The heating layer heats the material inside the tank from the outside, while the heat conduction channel inside the rotating shaft heats the material inside the tank from the inside. This combination of internal and external heating makes the heating faster and more uniform, effectively improving the melting efficiency. In addition, this invention divides the heating layer into two structurally symmetrical parts, each forming an independent circuit, further improving the heat supply circulation speed and melting speed.

[0023] Example

[0024] like Figures 1 to 4 As shown in one embodiment of the present invention, an internal and external heating smelting device of the present invention includes a base 1 and a horizontal tank 2. The tank 2 is fixedly installed on the base 1. The top of the tank 2 is provided with a material inlet 3, a vacuum hole 4, and a manhole 5. A rotating shaft 6 is rotatably connected inside the tank 2 and arranged along the axial direction of the tank 2. Several stirring blades are provided on the outer periphery of the rotating shaft 6. A driving device for driving the rotating shaft 6 to rotate is provided at one end of the tank 2. A material outlet 8 is provided at the lower part of the other end of the tank 2. A heating layer 9 is surrounded in the middle and lower part of the tank 2. A heat inlet 93 and a heat outlet 94 are provided on the heating layer 9. A heat conduction channel is opened axially inside the rotating shaft 6. A rotary joint 10 is installed at the end of the rotating shaft 6 away from the driving device. The rotary joint 10 is used to connect to an external heating device.

[0025] In use, materials are added to the tank 2 through the material inlet 3. The drive device drives the rotating shaft 6 to rotate, and the stirring blades stir the materials in the tank 2 as the rotating shaft 6 rotates. Heat transfer oil is pumped into the heating layer 9 through the heat inlet 93 and the rotary joint 10 for heating (when using heat transfer oil, the heat transfer oil enters from the top and exits from the bottom) or steam is pumped into the heating layer 9 for heating (when using steam, the steam enters from the bottom and exits from the top). The heating layer 9 heats the materials in the tank 2 from the outside of the tank 2, and the heat transfer channel in the rotating shaft 6 heats the materials in the tank 2 from the inside of the tank 2. The combination of internal and external heating makes the heating faster and more uniform.

[0026] Rotary joint 10 is prior art. Rotary joint 10 is also called a rotary seal or rotary joint. It enables the transmission of fluids (such as water, oil, steam, etc.) or gases between two relatively rotating parts and maintains good sealing performance.

[0027] Furthermore, as one embodiment of this utility model, such as Figure 3 As shown, the heating layer 9 includes a first half-heating layer 919 and a second half-heating layer 929, and the first half-heating layer 919 and the second half-heating layer 929 are respectively provided with a set of heat inlet 93 and heat outlet 94.

[0028] The first half-heating layer 919 and the second half-heating layer 929 have symmetrical structures and form independent circuits, which effectively improves the heating cycle speed and thus improves the melting speed.

[0029] Furthermore, as one embodiment of this utility model, the heating layer 9 includes multiple guide layers 95 parallel to the axial direction of the rotation axis 6, and adjacent guide layers 95 are interconnected. The provision of multiple guide layers 95 facilitates the sufficient heating of the material inside the tank 2 by heat transfer oil or heat transfer steam.

[0030] Furthermore, as one embodiment of this utility model, such as Figure 4 As shown, each flow guide layer 95 is provided with a connecting hole. Between adjacent flow guide layers 95, the connecting hole of one flow guide layer 95 is close to one end of the tank body 2, and the connecting hole of the other flow guide layer 95 is close to the other end of the tank body 2. This facilitates the full heating effect of the heat transfer oil or heat transfer steam in each flow guide layer 95.

[0031] Furthermore, as one embodiment of this utility model, a viewing window 11 is provided on the end side wall of the tank 2 to facilitate observation of the internal melting process.

[0032] Furthermore, as one embodiment of the present invention, the driving device includes a motor 71, a transmission belt 72, and a reducer 73. The motor 71 is connected to the driving pulley of the transmission belt 72, the driven pulley of the transmission belt 72 is connected to the input shaft of the reducer 73, and the output shaft of the reducer 73 is connected to the rotating shaft 6.

[0033] The above embodiments are not intended to limit the shape, material, structure, etc. of this utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
