Description

Technical Field

[0001] This utility model relates to the field of oleic acid purification technology, and in particular to an oleic acid distillation purification apparatus. Background Technology

[0002] Oleic acid mainly originates from nature and exists in the form of glycerides in animal and vegetable oils. Oleic acid can be obtained by separating oils with high oleic acid content through saponification and acidification. However, existing oleic acid distillation purification equipment has long distillation times and low efficiency, making it unsuitable for use.

[0003] Patent document CN215427382U discloses an "Oleic Acid Distillation and Purification Device," comprising a shell with three supporting legs fixedly connected to its bottom. A distillation column is fixedly connected inside the shell, with a discharge pipe and a feed pipe fixedly connected to its top and bottom, respectively. An equipment box is fixedly connected to one side of the outer wall of the shell, and a movable door is provided on one side of the outer wall of the equipment box. A mixing cylinder is located in the middle of the equipment box, and a filter layer is provided inside the mixing cylinder. Conveying pipes are fixedly connected to the top and bottom of the equipment box, and both conveying pipes pass through the mixing cylinder and are fixedly connected to nozzles. Heating components are provided outside both conveying pipes. This invention utilizes the interaction between heating elements, the mixing cylinder, and the filter layer. Heating elements heat the conveying pipes, allowing the raw material to pass through the filter layer and mix evenly. This ensures that the oleic acid raw material is sufficiently preheated before purification, thereby shortening the oleic acid distillation time and increasing the oleic acid production rate.

[0004] The device heats the conveying pipe with heating elements to preheat the oleic acid raw material. However, preheating is done only by heating elements on the outer wall of the conveying pipe, resulting in low heat transfer efficiency (indirect contact heating). Furthermore, the mixing method through the filter layer poses a risk of clogging. Therefore, it is necessary to provide an easy-to-use oleic acid distillation and purification device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an easy-to-use oleic acid distillation and purification device.

[0006] The oleic acid distillation and purification apparatus provided by this utility model includes a distillation column and an auxiliary mechanism. The top and bottom of the auxiliary mechanism are provided with a first preheating mechanism, and one end of the auxiliary mechanism is provided with a second preheating mechanism. One end of the second preheating mechanism is provided with a filter chamber. The inner cavity of the filter chamber is provided with a mesh plate, and the outer side of the filter chamber is provided with a cleaning mechanism. The two ends of the filter chamber are respectively connected to an inlet pipe and a outlet pipe, and one end of the outlet pipe is connected to the outer side of the distillation column.

[0007] As provided by this utility model, the oleic acid distillation and purification device preferably includes an auxiliary mechanism including a mixing chamber, one end of which is equipped with a motor, the output end of which is fixedly connected to a mixing shaft, and the outside of the mixing chamber is provided with heat insulation cotton.

[0008] As provided by this utility model, the auxiliary mechanism further includes a fixing hoop located on the outside of the insulation cotton. One end of the insulation cotton is fixedly connected to a docking block, and the other end is fixedly connected to a docking frame. The outside of the docking block is engaged with the inner cavity of the docking frame.

[0009] As provided by this utility model, the oleic acid distillation and purification device preferably includes a first preheating chamber. The top and bottom of the mixing chamber are fixedly connected to the first preheating chamber. The inner cavity of the first preheating chamber is equipped with a first electric heating rod, and the outer side of the first preheating chamber is equipped with a first temperature sensor.

[0010] As provided by this utility model, an oleic acid distillation and purification device is preferably provided, wherein the second preheating mechanism includes a second preheating chamber, the second preheating chamber is fixedly connected to one end of the mixing chamber, the inner cavity of the second preheating chamber is equipped with a second electric heating rod, and the outer side of the second preheating chamber is equipped with a second temperature sensor.

[0011] As provided by this utility model, an oleic acid distillation and purification device is preferably provided, wherein the cleaning mechanism includes a water pump, the water pump is installed at the top of the filter chamber, the outlet of the water pump is connected to a backwash pipe through a pipe, one end of the backwash pipe is connected to the top of the filter chamber, and the bottom of the filter chamber is connected to a drain pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This oleic acid distillation and purification unit achieves gradient preheating through a combination of a first and second preheating chamber, resulting in more uniform heating and facilitating subsequent distillation and purification. When the preheated raw material enters the filter chamber, the mesh plate disperses the material for further mixing before it enters the distillation column for further distillation. If the mesh plate becomes clogged, the solenoid valves on the outside of the inlet and outlet pipes can be closed to seal the filter chamber. The water pump inlet is then connected to an acid / alkali storage tank, and the acid / alkali solution is pumped into the filter chamber through a backflushing pipe to backflush the mesh plate. The wastewater generated during backflushing is discharged through a drain pipe, facilitating the cleaning of clogged mesh plates. This design solves the problems of low heat transfer efficiency in current devices that rely solely on heating elements on the outer wall of the delivery pipe for preheating, and the risk of clogging associated with mixing through the filter layer.

[0019] In this embodiment: after the oleic acid distillation feedstock is preheated by the first preheating mechanism 3, it can enter the mixing chamber 201. The mixing shaft 203 is driven by the motor 202 to mix the oleic acid distillation feedstock. After mixing, it enters the second preheating mechanism 4. By setting the insulation cotton 204, the insulation effect of the mixing chamber 201 is improved, and the heat loss of the oleic acid distillation feedstock is reduced.

[0020] As a technical optimization of this utility model, the auxiliary mechanism 2 also includes a fixing hoop 205, which is located on the outside of the insulation cotton 204. One end of the insulation cotton 204 is fixedly connected to a docking block 206, and the other end is fixedly connected to a docking frame 207. The outside of the docking block 206 is engaged with the inner cavity of the docking frame 207.

[0021] In this embodiment: after the insulation cotton 204 is wrapped around the outside of the mixing chamber 201, the docking block 206 can be inserted into the docking frame 207, and then the insulation cotton 204 can be fixed by the fixing hoop 205.

[0022] As a technical optimization of this utility model, the first preheating mechanism 3 includes a first preheating chamber 301. The top and bottom of the mixing chamber 201 are fixedly connected to the first preheating chamber 301. The inner cavity of the first preheating chamber 301 is equipped with a first electric heating rod 302, and the outer side of the first preheating chamber 301 is equipped with a first temperature sensor 303.

[0023] In this embodiment: the heating temperature of the first electric heating rod 302 is 70°C to 80°C. When using this device, the oleic acid distillation raw material can be transported to two first preheating chambers 301. The oleic acid distillation raw material is heated by the first electric heating rod 302 in the first preheating chamber 301. The first temperature sensor 303 can monitor the heating temperature of the oleic acid distillation raw material.

[0025] In this embodiment: the heating temperature of the second electric heating rod 402 is ≤150℃. After the oleic acid distillation raw material is initially heated by the first preheating chamber 301, it enters the second preheating chamber 401 after passing through the mixing chamber 201. The second electric heating rod 402 further heats the oleic acid distillation raw material, and then it enters the filter chamber 5. The first preheating chamber 301 and the second preheating chamber 401 work together to achieve gradient preheating and more uniform heating.

[0026] As a technical optimization of this utility model, the cleaning mechanism 7 includes a water pump 701, which is installed on the top of the filter chamber 5. The outlet of the water pump 701 is connected to a backwash pipe 702 through a pipe.

[0027] In this embodiment: when the preheated raw material enters the filter chamber 5, the mesh plate 6 disperses the raw material and further mixes it. Then the raw material enters the distillation column 1 for distillation. When the mesh plate 6 becomes clogged, the solenoid valves on the outside of the inlet pipe 8 and the outlet pipe 9 can be closed to seal the filter chamber 5. Then the inlet of the water pump 701 is connected to the acid / alkali storage tank. The acid / alkali is pumped into the filter chamber 5 through the backflushing pipe 702 by the water pump 701 to backflush the mesh plate 6. The wastewater generated by backflushing can be discharged through the drain pipe 703 to facilitate cleaning of the clogged mesh plate 6.

[0028] The working principle of the oleic acid distillation and purification device provided by this utility model is as follows: When using this device, the oleic acid distillation feedstock can be conveyed to two first preheating chambers 301, where the first electric heating rods 302 heat the feedstock. It then enters the mixing chamber 201, where the mixing shaft 203, driven by the motor 202, mixes the feedstock. Next, it enters the second preheating chamber 401, where the second electric heating rods 402 further heat the feedstock. Finally, it enters the filter chamber 5. The combined use of the first and second preheating chambers 301 achieves gradient preheating, resulting in more uniform heating. To facilitate subsequent distillation and purification, when the preheated raw material enters the filter chamber 5, the mesh plate 6 disperses the raw material and further mixes it. Then, the raw material enters the distillation column 1 for distillation. When the mesh plate 6 becomes clogged, the solenoid valves on the outside of the inlet pipe 8 and the outlet pipe 9 can be closed to seal the filter chamber 5. Then, the inlet of the water pump 701 is connected to the acid / alkali storage tank. The acid / alkali is pumped into the filter chamber 5 through the backflushing pipe 702 by the water pump 701 to backflush the mesh plate 6. The wastewater generated by backflushing can be discharged through the drain pipe 703 to facilitate cleaning of the clogged mesh plate 6.
