Description

Technical Field

[0001] This utility model relates to the technical field of biodiesel production equipment, and in particular to a dehydration device for biodiesel processing. Background Technology

[0002] Biodiesel is a clean fuel produced from renewable biomass such as vegetable oils, animal fats, or waste cooking oil through transesterification. Its main component is fatty acid methyl ester (FAME). It is an environmentally friendly alternative to traditional petrochemical diesel, characterized by its biodegradability, low pollution, and carbon neutrality. In the production process of biodiesel products using raw materials such as waste cooking oil and gutter oil, a small amount of water is generated, necessitating the removal of water from the biodiesel.

[0003] Prior art application number 201821745510.1 discloses a biodiesel dehydration device, including: an air pump; a shell with an opening on the top surface and a liquid outlet on the bottom surface; a dryer fitted onto the outer side of the shell; a screen built into the shell; and a desiccant arranged between the screen and the shell. Compared with the prior art, the present invention has the following advantages: The biodiesel dehydration device of the present invention includes a dryer. When the desiccant loses its ability to absorb water, the input of biodiesel is stopped, and the desiccant is directly dried on the equipment using the dryer to restore its water absorption performance. There is no need to replace the desiccant, making the operation simpler and helping to improve production efficiency.

[0004] However, the above technical solution has some problems: the dehydration process needs to be stopped when drying the desiccant, which seriously affects the efficiency of the dehydration process. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a dehydration device for biodiesel processing. The device utilizes a turntable to rotate a separation box, filter screen, and desiccant. The separation box, filter screen, and desiccant sequentially pass through an oil inlet pipe and an exhaust pipe. A heating mechanism heats the desiccant, and moisture is discharged through the exhaust pipe. This ensures continuous operation of the dehydration device, improves production efficiency, and provides a simple, efficient, safe, reliable, and easy-to-operate dehydration device.

[0006] This utility model is achieved through the following technical solution: a dehydration device for biodiesel processing is provided, including a housing; a turntable is rotated inside the housing, and several separation boxes are arranged evenly along the circumference of the turntable on the turntable, with an oil outlet at the bottom of the separation box; several cylindrical filter screens are arranged in sequence with their openings facing upwards inside the separation box, and a desiccant is placed between the filter screens; the housing is connected to an oil inlet pipe and an exhaust pipe, and the oil inlet pipe and the exhaust pipe move towards the openings of the filter screens; a heating mechanism is provided on the housing, and the working end of the heating mechanism is close to the exhaust pipe; the turntable drives the separation boxes, filter screens and desiccant to rotate, and the separation boxes, filter screens and desiccant pass through the oil inlet pipe and the exhaust pipe in sequence, the heating mechanism heats the desiccant and discharges the moisture through the exhaust pipe, ensuring continuous operation of the dehydration device and improving production efficiency.

[0007] As an optimization, the heating mechanism includes an electromagnetic mechanism and a closed circuit disposed between the filter screens, and the magnetic field ranges of the closed circuit and the electromagnetic mechanism intersect; heat is directly dissipated between the desiccant through the electromagnetic mechanism and the closed circuit, thereby improving the heating effect.

[0008] As an optimization, a spiral coil is used in the closed circuit; the heating effect is increased by using a spiral coil.

[0009] As an optimization, the top of the outermost filter screen is connected to the separation chamber via a sealing cap; the sealing cap reduces biodiesel evaporation between the separation chamber and the filter screen.

[0010] As an optimization, the exhaust pipe is equipped with a filter device, and the bottom of the filter device is located directly above the filter screen opening; the volatile biodiesel is filtered through the filter device and reintroduced into the filter screen.

[0011] The beneficial effects of this utility model are as follows: the turntable drives the separation box, filter screen and desiccant to rotate, the separation box, filter screen and desiccant pass through the oil inlet pipe and exhaust pipe in sequence, the heating mechanism heats the desiccant and discharges the moisture through the exhaust pipe, ensuring that the dehydration device works continuously and improving production efficiency; the electromagnetic mechanism and closed circuit directly dissipate heat in the middle of the desiccant, improving the heating effect.

[0016] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0017] like Figure 1 and Figure 2 The present invention discloses a dehydration device for biodiesel processing, comprising a housing 1; a turntable 2 is mounted inside the housing 1, and several separation boxes 3 are arranged evenly along the circumference of the turntable 2 on the turntable 2, with an oil outlet 301 at the bottom of the separation box 3; several cylindrical filter screens 4 are arranged in sequence with their openings facing upwards inside the separation box 3, and a desiccant 5 is placed between the filter screens 4; the housing 1 is connected to an oil inlet pipe 6 and an exhaust pipe 7, and the oil inlet pipe 6 and the exhaust pipe 7 move towards the opening of the filter screen 4; a heating mechanism 8 is provided on the housing 1, and the working end of the heating mechanism 8 is close to the exhaust pipe 7; the connection between the oil inlet pipe 6 and the housing 1 is located directly above the opening of the filter screen 4, and the connection between the exhaust pipe 7 and the housing 1 is also located directly above the opening of the filter screen 4; a drive mechanism 12 is provided on the housing 1 to drive the turntable 2 to rotate, and the drive mechanism 12 is existing technology and can be an electric motor; the exhaust pipe 7 is connected to the air inlet of a fan 11.

[0018] Biodiesel is fed into the housing 1 through the oil inlet pipe 6. The biodiesel enters the filter screen 4 and passes through the filter screen 4 into the separation box 3. The desiccant 5 between the filter screens 4 absorbs the moisture in the biodiesel. The dehydrated biodiesel in the separation box 3 is discharged through the oil outlet 301. After the desiccant 5 absorbs a certain amount of moisture, the turntable 2 is rotated. The turntable 2 drives the separation box 3, filter screen 4 and desiccant 5 to rotate. The separation box 3, filter screen 4 and desiccant 5 directly below the oil inlet pipe 6 are renewed. The desiccant 5 that needs to be dried reaches directly below the exhaust pipe 7. The heating mechanism 8 is activated. The heating mechanism 8 heats the desiccant 5 directly below the exhaust pipe 7. The moisture in the desiccant 5 evaporates and is discharged through the exhaust pipe 7.

[0019] like Figure 1 The heating mechanism 8 shown includes an electromagnetic mechanism 802 and a closed circuit 801 disposed between the filter screens 4, and the magnetic field ranges of the closed circuit 801 and the electromagnetic mechanism 802 intersect; the electromagnetic mechanism 802 is connected to a rheostat, and the magnitude of the current in the electromagnetic mechanism 802 is changed by the rheostat.

[0020] When the electromagnetic mechanism 802 is activated, it emits a constantly changing magnetic field. The closed circuit 801 cuts the magnetic field lines to generate current and heat. The heat generated by the closed circuit 801 heats the desiccant 5, causing the moisture in the desiccant 5 to evaporate and be discharged through the exhaust pipe 7.

[0021] like Figure 1 The top of the outermost filter screen 4 shown is connected to the separation box 3 via a sealing cover 9.

[0022] The biodiesel remaining between the separator 3 and the filter screen 4 evaporates and accumulates on the sealing cap 9, which prevents the biodiesel from evaporating.

[0023] like Figure 1 The exhaust pipe 7 shown is equipped with a filter device 10, and the bottom of the filter device 10 is located directly above the opening of the filter screen 4; the filter device 10 is prior art.

[0024] The volatile biodiesel enters the exhaust pipe 7 along with the steam. The filter device 10 filters the steam. The volatile biodiesel gathers on the filter device 10 and collects at the bottom of the filter device 10 under the action of gravity. The biodiesel on the filter device 10 falls into the filter screen 4 under the action of gravity.

[0025] In actual production, biodiesel is input into the housing 1 through the oil inlet pipe 6. The biodiesel enters the filter screen 4 and passes through the filter screen 4 sequentially into the separation box 3. The desiccant 5 between the filter screens 4 absorbs the moisture in the biodiesel. The dehydrated biodiesel in the separation box 3 is discharged through the oil outlet 301. After the desiccant 5 absorbs a certain amount of moisture, the turntable 2 is rotated. The turntable 2 drives the separation box 3, filter screen 4, and desiccant 5 to rotate, and the separation box 3, filter screen 4, and desiccant 5 directly below the oil inlet pipe 6 are renewed. The desiccant 5 that needs to be dried reaches directly below the exhaust pipe 7. The electromagnetic mechanism 802 is activated, and the electromagnetic mechanism 802 generates... A constantly changing magnetic field is generated. The closed circuit 801 cuts the magnetic field lines to generate current and heat. The heat generated by the closed circuit 801 heats the desiccant 5, and the moisture in the desiccant 5 evaporates and is discharged through the exhaust pipe 7. The biodiesel remaining between the separation box 3 and the filter screen 4 evaporates and accumulates on the sealing cover 9, which prevents the biodiesel from evaporating. The evaporated biodiesel enters the exhaust pipe 7 with the steam. The filter device 10 filters the steam. The evaporated biodiesel accumulates on the filter device 10 and gathers at the bottom of the filter device 10 under the action of gravity. The biodiesel on the filter device 10 falls into the filter screen 4 under the action of gravity.
