Description

Technical Field

[0001] The utility model relates to the technical field of unloading and sampling devices for liquid bag packages of high freezing point liquid materials, and particularly relates to an unloading and sampling device for liquid bag packages of raw materials with high freezing point of biodiesel. Background Art

[0002] Biodiesel generally uses waste animal and vegetable oils and fats as raw materials, and is prepared by carrying out esterification reaction and alcoholysis reaction with methanol to generate fatty acid methyl ester. As the raw material oil of biodiesel, the freezing points of waste animal and vegetable oils and fats in different batches are different; for raw material oils with high freezing points, due to the difficulty of unloading and sampling, it is necessary to simply heat and melt them to complete unloading and sampling. In the prior art, the unloading and sampling operation of liquid bag packages of raw material oils with high freezing points of biodiesel generally adopts the method of directly inserting a steam pipe into the liquid bag package from the outlet male end of the raw material oil liquid bag package for heating. During this heating and melting process, there is no closed operation. After the high freezing point raw material oil in the liquid bag package is heated and melted, it flows by itself into an intermediate tank with steam heating and insulation. There is a diversion pipeline in front of this intermediate tank leading to a sampling tank with an air stirring and steam heating device, and sampling is carried out in the sampling tank. Finally, the raw material oil in the intermediate tank is pumped to a sedimentation tank to complete the unloading operation; there are three defects. One is that during the heating and melting process, due to the lack of closed operation, steam leakage inevitably occurs, resulting in heat loss. The second is that the heating and melting process is not closed and relies on self-flow to the intermediate tank, not only melting slowly, but also having low unloading efficiency. The third is that the setting of the intermediate tank makes the whole device structure complex, increasing the equipment manufacturing cost. Summary of the Invention

[0013] As Figure 1 , Figure 2 shown, the unloading and sampling device for the liquid bag package of high freezing point raw material oil for biodiesel of the present utility model includes a steam pipe 1, a quick connector, a steam pipe joint 7, an unloading valve 8, a valve before pump 9, a charging pump 10, a return valve 11, a bottom valve of tank 12, an air compressor inlet 13, a steam and water inlet 14, a steam and water outlet 15, a sampling valve 16, a feed inlet of sedimentation tank 17, a liquid bag package of high freezing point raw material oil for biodiesel 18 and a sampling tank 19; the steam pipe 1 is evenly provided with a plurality of steam holes including an upper steam hole 2, a left steam hole 3 and a right steam hole 4; the left end of the quick connector is a female end of quick connector 5, which is sleeved on the male end of the unloading port of the liquid bag package, and the right end is a male end of quick connector 6 for sleeving a hose, and the other end of the hose is connected to a hard pipe and then successively connected to an unloading valve 8, a valve before pump 9 and a charging pump 10; the steam pipe joint 7 is welded and fixed on the quick connector, its left end is inserted into the quick connector and connected to the steam pipe 1, and the right end is exposed and connected to a steam hose; the charging pump 10 is used for feeding and discharging the steam pressure in the liquid bag package, and the outlet pipeline of the charging pump 10 is divided into two paths, one path is connected to the feed inlet of sedimentation tank 17, and the other path is connected to the top of the sampling tank 19 with a steam and water inlet 14 and a steam and water outlet 15 after passing through a sampling valve 16, and the conical bottom outlet of the sampling tank 19 is connected to the pipeline between the unloading valve 8 and the valve before pump 9 after successively connecting a bottom valve of tank 12 and a return valve 11; the air compressor inlet 13 is used for introducing compressed air to stir the raw material oil in the sampling tank 19, and it is arranged on the pipeline between the return valve 11 and the bottom valve of tank 12.

[0014] During operation, insert the steam pipe 1 into the high freezing point raw oil liquid bag package 18. If the insertion is blocked, a small channel can be dug at the discharge port of the high freezing point liquid bag package raw oil 18 using tools to facilitate the insertion of the steam pipe 1, and make the upper steam hole 2 face upward, the left steam hole 3 face left, and the right steam hole 4 face right. The three-sided steam output can quickly dissolve the high freezing point raw oil in the liquid bag package from three sides. Since the downward direction is close to the bottom of the liquid bag, there is no need to make a steam hole. After inserting the steam pipe 1, put the female end 5 of the quick connector on the male end of the discharge port of the liquid bag package. Before starting unloading, close the return valve 11 and the bottom valve 12 of the tank, and open the unloading valve 8, the valve 9 before the pump, and the sampling valve 16. The sampling valve 16 is slightly opened at the beginning and adjusted to uniform discharge as the unloading process progresses.

At the same time, turn on the feeding pump 10 and introduce the high-temperature steam water into the steam water inlet 14 to heat the high freezing point raw oil in the sampling tank 19. The steam water is discharged from the steam water outlet 15. The raw oil unloaded from the high freezing point raw oil liquid bag package 18 is pumped to the feed inlet 17 of the settling tank by the feeding pump 10, and a part of the raw oil is led through the sampling valve 16 into the sampling tank 19. After unloading is completed, close the unloading valve 8 and the sampling valve 16, and at the same time turn off the feeding pump 10. Introduce compressed air through the compressed air inlet 13, and at the same time open the bottom valve 12 of the tank to agitate the high freezing point raw oil in the sampling tank 19 with air to make it uniform, and take a comprehensive sample after uniform agitation. After taking the comprehensive sample, close the compressed air inlet 13, open the return valve 11 and turn on the feeding pump 10, and pump the remaining high freezing point raw oil in the sampling tank 19 after sampling to the feed inlet 17 of the settling tank and into the settling tank.
