Description

Technical Field

[0001] This utility model belongs to the technical field of ester product production equipment, specifically relating to a device for adding stabilizers to ester products. Background Technology

[0002] In the production and storage of ester products (such as biodiesel), antioxidants (such as BHT, butylated hydroxytoluene) are typically added to delay oxidative rancidity and improve the product's oxidative stability. Currently, the main method for adding antioxidants is a one-time addition method, where BHT is added to the storage tank or reaction vessel all at once and mixed thoroughly by heating and stirring. However, this method has the following technical drawbacks: Uneven dispersion of antioxidants: When BHT is added in large quantities at one time, it is easy to form agglomerates due to excessively high local concentrations, resulting in uneven mixing and affecting the antioxidant effect. To address this, an apparatus for adding stabilizers to ester products is provided.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide an apparatus for adding stabilizers to ester products, thereby solving the problems of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An apparatus for adding stabilizers to ester products includes an inlet pipe fixedly connected to an inlet at the top edge of a storage tank, an L-shaped outlet pipe with an electric valve fixedly connected to an outlet at the bottom of the storage tank, a hopper fixedly connected to an inlet near the top of the outer wall of the storage tank via an inlet pipe, the hopper containing stabilizers, a stirring rod rotatably connected to the center of the top of the storage tank, a high-shear dispersion disc fixedly connected to the bottom of the stirring rod, a transmission device connected between the outer periphery of the top of the stirring rod and the storage tank, an electric heating plate with a circular cross-section fixedly connected to the inner wall of the storage tank, and an adjustable intermittent baffle assembly connected between the stirring rod and the interior of the storage tank; the adjustable intermittent baffle assembly is used to drive the stabilizer in the hopper to be intermittently added to the storage tank, and the amount of intermittent addition is adjustable.

[0006] Preferably, the adjustable intermittent baffle assembly includes a rotating plate fixed above the middle of the outer wall of the stirring rod by two symmetrically arranged first connecting rods. The rotating plate has a circular cross-section, and the outer circumferential wall of the rotating plate is movably fitted to the inner wall of the storage tank. A feed port is provided on the rotating plate, and the arc length of the cross-section of the feed port is equal to one-quarter of the circumference of the cross-section of the rotating plate. The inner width of the feed port matches the inner width of the bottom end of the feed pipe.

[0007] Preferably, an adjusting plate slides on the inner wall of the rotating plate, and the cross-section of the adjusting plate is also annular. The outer diameter of the adjusting plate matches the inner diameter of the rotating plate, and two symmetrically arranged second connecting rods are fixedly connected to the inner wall of the adjusting plate.

[0008] Preferably, the inner side of the stirring rod has a moving channel with a cross-shaped cross-section, and the two second connecting rods extend into the moving channel at their close ends and are fixed to the same moving block with a square cross-section. The moving block also slides within the moving channel.

[0009] Preferably, the cross-sections of the moving block and the two second connecting rods together form a cross shape, and the vertical cross-section width of the adjusting plate is larger than the inner width of the feed inlet.

[0010] Preferably, a hand-tightening screw is rotatably connected to the top of the moving block, the hand-tightening screw is threaded to the inner side of the stirring rod, a handle is fixedly connected to the top extension of the hand-tightening screw, and a hand-tightening screw is threaded to the outer wall of the stirring rod near its top, the end of the hand-tightening screw after being tightened abuts against the outer side of the hand-tightening screw.

[0011] Compared with the prior art, the present invention has the following beneficial effects: (1) The device for adding stabilizers to ester products according to this utility model firstly injects a known amount of biodiesel into the storage tank through the inlet pipe, and drives the stirring rod to rotate the high-shear dispersion disk through the transmission device, which is combined with the electric heating plate for heating. At the same time, the two first connecting rods drive the rotating plate to rotate through the rotation of the stirring rod. When the feed port coincides with the bottom opening of the feed pipe, the antioxidant BHT in the hopper can intermittently enter the storage tank and can be mixed evenly with the biodiesel, avoiding the problem of excessive local concentration and agglomeration caused by excessive feed at one time. This ensures uniform mixing and significantly improves antioxidant effects. Secondly, when the amount of biodiesel is low, the hand screw can be loosened, and the hand screw can be rotated by the handle. This causes the moving block to move the adjusting plate connected to the two second connecting rods up and down on the inner wall of the rotating plate, partially blocking the feed inlet and reducing the width of the feed outlet. Conversely, when the amount of biodiesel is high, the hand screw is reversed, causing the adjusting plate to move up and increasing the width of the feed outlet. This allows for the adjustment of the amount of BHT added intermittently according to the amount of biodiesel, to meet the needs of different production conditions. Attached Figure Description

[0018] The discharge from the L-shaped discharge pipe 14 can be connected to subsequent processes; The transmission device 17 includes two sprockets and a chain connecting the two sprockets. One sprocket is fixed to the top periphery of the stirring rod 15, and the other sprocket is fixed to the output shaft of the geared motor. The geared motor can be set to adjust the rotation speed and realize the adjustment of the stirring speed.

[0019] Furthermore, such as Figure 1-3As shown, in order to enable intermittent BHT injection and adjust the amount of intermittent BHT injection according to the amount of biodiesel, an adjustable intermittent feed baffle assembly 2 is provided. This assembly includes a rotating plate 22 fixed above the middle of the outer wall of the stirring rod 15 via two symmetrically arranged first connecting rods 21. The rotating plate 22 has a circular cross-section, and its outer circumferential wall movably fits against the inner wall of the storage tank 1. A feed inlet 23 is provided on the rotating plate 22, and the arc length of the feed inlet 23 is equal to one-quarter of the circumference of the rotating plate 22's cross-section. The inner width of the feed inlet 23 matches the inner width of the bottom end of the feed pipe 12. An adjusting plate 24 slides on the inner wall of the rotating plate 22. The adjusting plate 24 also has a circular cross-section, and its outer diameter matches the inner diameter of the rotating plate 22. Two pairs of... The second connecting rod 25 is provided. The inner side of the stirring rod 15 has a moving channel 27 with a cross-shaped cross-section. The two ends of the two second connecting rods 25 extend into the moving channel 27 and are fixedly connected to the same moving block 26 with a square cross-section. The moving block 26 also slides in the moving channel 27. The cross-sections of the moving block 26 and the two second connecting rods 25 are cross-shaped. The vertical cross-section width of the adjusting plate 24 is larger than the inner width of the feed port 23. The top of the moving block 26 is rotatably connected to a hand screw 28. The hand screw 28 is threaded to the inner side of the stirring rod 15. The top extension of the hand screw 28 is fixedly connected to a handle. The outer wall of the stirring rod 15 and near its top is threaded with a hand screw 29. The end of the hand screw 29 after being locked is pressed against the outer side of the hand screw 28.

[0020] The vertical cross-sections of both the first connecting rod 21 and the second connecting rod 25 are square structures; The inner top and bottom walls of the feed inlet 23 are inclined, and their inclination matches that of the bottom inner wall of the feed pipe 12.

[0021] In actual use, firstly, a known amount of biodiesel is injected into the storage tank 1 through the inlet pipe 11. The transmission device 17 drives the stirring rod 15 to rotate the high-shear dispersion disc 16, which is then heated by the electric heating plate 18. Simultaneously, the two first connecting rods 21, through the rotation of the stirring rod 15, drive the rotating plate 22 to rotate. When the feed port 23 aligns with the bottom opening of the feed pipe 12, the antioxidant BHT in the hopper 13 can intermittently enter the storage tank 1 and mix evenly with the biodiesel. This avoids the problem of excessive local concentration and agglomeration caused by excessive feeding at one time, thus improving the mixing effect. The uniformity and antioxidant effect are greatly improved. Secondly, when the amount of biodiesel is small, the hand screw 29 can be loosened and the hand screw 28 can be rotated by the handle. This causes the moving block 26 to drive the adjusting plate 24 connected by the two second connecting rods 25 to move up and down on the inner wall of the rotating plate 22, which can partially block the feed port 23, thereby reducing the width of the feed port 23. Conversely, when the amount of biodiesel is large, the hand screw 28 is reversed to cause the adjusting plate 24 to move up, thereby increasing the width of the feed port 23. This allows the amount of BHT added intermittently to be adjusted according to the amount of biodiesel to meet the needs of different production conditions.
