Description

Technical Field

[0001] The utility model relates to the technical field of biodiesel production, in particular to a system for producing biodiesel from animal and vegetable oils and fats. Background Art

[0002] Biodiesel is obtained by subjecting vegetable oils (such as rapeseed oil, soybean oil, peanut oil, etc.), animal fats or waste oils and fats to esterification and transesterification reactions with short-chain alcohols such as methanol or ethanol to obtain fatty acid methyl esters or ethyl esters.

[0003] In the prior art, a system for producing biodiesel from waste animal and vegetable oils and fats with the published patent number CN217725532U is disclosed. In this system, a three-phase separator introduces unnecessary residues and a mixture (glycerol and water) into a first storage tank and a second storage tank respectively, and the remaining mixed fatty acids, fatty acid glycerides, oils and fats, etc. are cached in a second buffer tank for the reaction of the next process. Glycerol in the glycerol and water mixture is a valuable chemical raw material and is widely used in many fields such as pharmaceuticals, cosmetics, and food. By separating glycerol, it can be recycled and used in other industrial productions to achieve the recycling of resources. Nowadays, most glycerol separation devices can only filter and adsorb impurities and pigments inside glycerol, and when replacing the filter and adsorption components, it requires many steps, causing cumbersome problems. Content of the Utility Model

[0030] Please refer to Figures 1 - 5 , a system for producing biodiesel from animal and vegetable oils and fats, comprising a storage tank 1 and a filtering device 2 (the storage tank 1 is the second buffer tank in the background art), and an output pipe 11 is connected to the storage tank 1.

[0031] The filtering device 2 includes a filtering box 21. The output end of the output pipe 11 extends into the filtering box 21. A switching rod 22 is rotatably connected to the filtering box 21. Symmetrical cylinders 23 are connected to the switching rod 22. The output pipe 11 of the output pipe 11 is located above the cylinders 23. A support ring 24 is arranged in the cylinders 23. A filtering adsorbent 25 supported by the support ring 24 is arranged at the bottom of the cylinders 23. The filtering adsorbent 25 is in a barrel shape. The adsorption part of the filtering adsorbent 25 protrudes from the bottom end of the cylinders 23, so that the area of the adsorption and filtering part is large. After the bottom is blocked, the peripheral surface can also adsorb and filter. An access opening 26 is opened at the upper end of the filtering box 21 for accessing the filtering adsorbent 25. The access opening 26 can be sealed with a cover plate, which is not shown in the figure. A detachable connecting rod 27 is connected to the filtering adsorbent 25. A sliding sleeve 271 is arranged at the upper end of the connecting rod 27. The connecting rod 27 and the sliding sleeve 271 can be reused. The top surface of the sliding sleeve 271 is flush with the upper surface of the cylinders 23. The sliding sleeve 271 slides upward and protrudes from the cylinders 23. The sliding sleeve 271 protruding from the cylinders 23 is convenient for holding by hand and is convenient for taking and placing.

[0032] The switching rod 22 is provided with a limiting part 221. An inserting rod 28 is inserted into the limiting part 221. Symmetric inserting blocks 29 are fixed on the filter box 21. Insertion holes 291 into which the end of the inserting rod 28 is inserted are formed on the inserting blocks 29. By inserting the inserting rod 28 into the insertion holes 291, the switching rod 22 is fixed. When replacing the filter suction accessory 25, first pull out the inserting rod 28, and then rotate the switching rod 22. When the limiting part 221 contacts the limiting plate 211, stop rotating. At this time, the through hole of the limiting part 221 is aligned with the insertion hole 291 on the inserting block 29. Directly insert the inserting rod 28. At this time, the access port 26 and the cylinder body 23 below the baffle 9 are switched. The baffle 9 contacts the cylinder body 23, and the filter suction accessory 25 under the access port 26 is released from its limit. The sliding sleeve 271 slides upward, and the filter suction accessory 25 under the access port 26 is taken out and replaced through the connecting rod 27.

[0033] A baffle 9 is arranged at the output end of the output pipe 11. The baffle 9 is fixed to the output pipe 11. The baffle 9 contacts the upper end of the cylinder body 23. The diameter of the baffle 9 is larger than the diameter of the cylinder body 23. The baffle 9 blocks the upper end of the cylinder body 23, preventing the mixed liquid of glycerol and water from splashing out of the cylinder body 23. The baffle 9 contacts the sliding sleeve 271, and together with the support ring 24, the filter suction accessory 25 is limited, preventing the filter suction accessory 25 from being floated by too much mixed liquid of glycerol and water in the filter box 21.

[0034] A separation device 3 is arranged on one side of the filtering device 2. The separation device 3 is connected to the filtering device 2 through a connecting pipe 4. A control valve I 5 is arranged on the connecting pipe 4. The separation device 3 includes a separation tank 31. The control valve I 5 controls the communication between the filter box 21 and the separation tank 31. The control valve I 5 is a prior art and will not be described further.

[0035] A rotating stirring column 32 is arranged on the separation tank 31. Stirring rods 33 are fixed longitudinally on the stirring column 32. An arc-shaped rod 34 is connected to the end of the stirring rod 33. The arc-shaped rods 34 are distributed longitudinally, so that the stirring area is larger and the stirring effect is better. The upper end of the stirring column 32 is connected to a driving motor 8.

[0036] A plurality of heating columns 35 are arranged in the separation tank 31. Transverse heating rods 36 are connected to the heating columns 35. The upper ends of the heating columns 35 are connected to heating components (not shown in the figure as they are prior art). The transverse heating rods 36 extend towards the stirring column 32, and the heating effect is more uniform. An outflow pipe 6 is arranged at the lower end of the separation tank 31. A control valve II 7 is arranged on the outflow pipe 6. The control valve II 7 is a prior art and will not be described further.

[0037] An evaporation pipe 37 is connected to the upper end of the separation tank 31, and an inclined plate 311 is connected to the upper end inside the separation tank 31. The inclined plate 311 positions the evaporation pipe 37 at the highest point, facilitating the entry of water vapor into the evaporation pipe 37. The output end of the evaporation pipe 37 is connected to a condensing pipe 38, and the outlet of the condensing pipe 38 is connected to a water storage tank 39. The condensing pipe 38 is a prior art and will not be elaborated further.

[0038] First, the mixture of glycerol and water is discharged into the interior of the filtration box 21 through the output pipe 11 on the storage tank 1, enabling the mixture of glycerol and water to filter out impurities inside the glycerol when passing through the filtration and adsorption member 25. The filtered mixture of glycerol and water enters the bottom of the inner cavity of the filtration box 21. Then, the control valve 1 5 is opened to allow the mixture of glycerol and water to enter the interior of the separation tank 31. Subsequently, the mixture of glycerol and water is heated by the heating column 35 and the horizontal heating rod 36, and during the heating process, it is stirred by the stirring rod 33 and the arc-shaped rod 34. Since the boiling point of water is lower than that of glycerol, water evaporates into water vapor during the heating process and enters the condensing pipe 38, where it condenses into water and flows into the interior of the water storage tank 39. Then, the control valve 2 7 provided on the outflow pipe 6 is opened to allow the purified glycerol to enter the interior of a glycerol collection box (not shown in the figure).

[0039] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are merely examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and without departing from the said principles, any changes or modifications can be made to the embodiments of the present invention.
