Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of biomass diesel, specifically to a gutter oil step -by -step heating purification device for biomass diesel production. BACKGROUND

[0002] In the production process of biomass diesel, gutter oil as a renewable resource, its purification and utilization have been concerned. However, the traditional gutter oil purification method often has low filtration efficiency, unstable product quality, high production cost and other problems. Especially when the gutter oil temperature is too low, its fluidity will decrease significantly, thereby affecting the smooth progress of the filtration screening process, further reducing the production efficiency.

[0003] The traditional purification device often uses single layer filter screen or simple multi layer filter screen structure in the aspect of filtration, and this design can not effectively remove the impurities and solid particles in the gutter oil, thereby affecting the purity of the final product. In addition, the traditional purification device also has defects in heating, and often cannot ensure that the air temperature in the box reaches the ideal level, resulting in poor fluidity of the gutter oil, further affecting the purification effect.

[0010] 1. Through the ingenious design of three layers of filter screen plates and two flow guides, the step-by-step heating and purification of gutter oil is realized. This design not only improves the filtering efficiency, but also ensures the quality of the purified biomass diesel. Each layer of filter screen plate can carefully select the gutter oil and remove impurities and solid particles, making the final product more pure.

[0011] 2. The application of the heating device allows the air temperature in the box to be raised, thereby avoiding the flowability problem of gutter oil due to too low temperature.

[0016] The technical solutions in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model. EMBODIMENT

[0017] As Figure 1 shown, the utility model embodiment provides a kind of gutter oil step-by-step heating purification device for biomass diesel production, including box 1, feed inlet 2, servo motor 4 and purification equipment 10, two feed inlets 2 are symmetrically set at the top of box 1, multiple filter screen plates 3 are fixedly connected with equidistance in the inside of box 1, servo motor 4 is fixedly connected at the top of box 1, servo motor 4 is between two feed inlets 2, the driving end of servo motor 4 is fixedly connected with driving rod 5, driving rod 5 is fixedly connected with two flow guides 6, the shape of two flow guides 6 is all conical body, two flow guides 6 are located between adjacent two filter screen plates 3 respectively, driving rod 5 penetrates multiple filter screen plates 3, multiple cleaning leaves 7 are fixedly connected with equidistance on the both sides of driving rod 5, multiple cleaning leaves 7 are contacted with the top of multiple filter screen plates 3, the both inner walls of box 1 are fixedly connected with fixed plate 8, fixed plate 8 is below multiple filter screen plates 3, fixed plate 8 is symmetrically inclined to be arranged, purification equipment 10 is fixedly connected at the inner bottom wall of box 1, the top of purification equipment 10 is provided with guide pipe 11, the bottom of purification equipment 10 is fixedly connected with discharge outlet 12, discharge outlet 12 penetrates the bottom of box 1 and extends to the outside of box 1.

[0018] The both inner walls of box 1 are fixedly connected with heating equipment 9, and heating equipment 9 is below fixed plate 8. Heating equipment 9 is below fixed plate 8, which can ensure that the air and gutter oil in box 1 are heated more uniformly, avoiding the situation of local temperature being too high or too low. The position of heating equipment 9 enables heat to be more effectively transferred to the gutter oil, improving the energy utilization efficiency. Because heating is more uniform and efficient, the energy consumption of heating equipment 9 can be reduced, and the production cost can be reduced.

[0019] The shape of filter screen plate 3 is cylindrical side surface, the mesh size of multiple filter screen plates 3 decreases from top to bottom in turn, and filter screen plate 3 is directly below feed inlet 2. The design of cylindrical side surface increases the filtering area of filter screen plate 3, so that the gutter oil can be more fully contacted with filter screen plate 3, and the filtering efficiency is improved. The mesh size decreases from top to bottom in turn, which realizes the effect of step-by-step filtration, and can more effectively remove impurities and solid particles in gutter oil. The design of cylindrical side surface also optimizes the flow channel of gutter oil, so that the gutter oil can flow more smoothly through filter screen plate 3, reducing the risk of blockage and accumulation.

[0020] The material guide pipe 11 is located directly below the gap between the two fixed plates 8. The material guide pipe 11 is located directly below the gap between the two fixed plates 8, which can ensure that the gutter oil filtered through the three layers of filter screens 3 can be collected into the material guide pipe 11, avoiding waste and leakage of the gutter oil. This design simplifies the purification process, making the gutter oil more directly enter the purification equipment 10 for purification treatment. Because the gutter oil can more smoothly enter the purification equipment 10, the production efficiency of the entire purification process can be improved.

[0021] Working principle: When using the gutter oil step-by-step heating purification device for biomass diesel production, gutter oil can be added to the box 1 through the feed inlet 2, and the gutter oil falls onto the uppermost filter screen 3. Because the shape of the filter screen 3 is a conical side, the gutter oil on the filter screen 3 can be filtered and screened along the inclined surface of the filter screen 3. The gutter oil filtered and screened through the upper part of the filter screen 3 will flow directly onto the upper part of the inclined surface of the filter screen 3 located in the middle. The gutter oil filtered and screened through the lower part of the filter screen 3 will flow onto the flow guide plate 6 located below the filter screen 3. The flow guide plate 6 can disperse the gutter oil onto the upper part of the inclined surface of the filter screen 3 located in the middle, so that the gutter oil filtered and screened through the uppermost filter screen 3 will be concentrated on the upper part of the inclined surface of the filter screen 3 located in the middle, and then the gutter oil can be filtered and screened along the inclined surface of the filter screen 3. Through the two flow guide plates 6 and the three layers of filter screens 3, the gutter oil can be filtered and screened three times along the upper inclined surface of the filter screen 3. Because the gutter oil is filtered and screened through the three layers of filter screens 3 in turn, and the mesh size of the three layers of filter screens 3 decreases from top to bottom, the filtering effect of the three layers of filter screens 3 on the gutter oil is better. During the filtering and screening process of the gutter oil through the three layers of filter screens 3, the air in the box 1 can be heated by the heating device 9, so that the gutter oil will be heated, avoiding the influence of low temperature of the gutter oil on the flowability of the gutter oil, so that the influence on the filtering and screening effect of the gutter oil through the filter screen 3 can be avoided. Moreover, the servo motor 4 can drive the drive rod 5 to drive the cleaning blade 7 to rotate, and the cleaning blade 7 is in contact with the filter screen 3, so that the cleaning blade 7 can clean and concentrate the residues on the filter screen 3 that do not pass through the filter, so that the residues on the filter screen 3 are concentrated in the middle area of the filter screen 3, avoiding the residues from blocking the mesh of the filter screen 3 and affecting the filtering and screening effect of the filter screen 3 on the gutter oil. Because the servo motor 4 can drive the drive rod 5 to drive the flow guide plate 6 to rotate, the dispersion effect of the flow guide plate 6 on the gutter oil is better. The gutter oil filtered and screened through the three layers of filter screens 3 will be concentrated into the material guide pipe 11 on the purification equipment 10 through the fixed plates 8. The gutter oil can be concentrated into the purification equipment 10 through the material guide pipe 11 for purification. When the gutter oil is purified, it is discharged from the box 1 through the discharge port 12 on the purification equipment 10.
