[0002] Biodiesel is a green and renewable biomass energy with broad development prospects. Oxidation stability refers to the ability of petroleum products to resist heat and oxidation and maintain their properties without permanent changes when stored for a long time or used at high temperatures for a long time. Due to oxidation, petroleum products often have a decrease in free alkali content or an increase in free organic acid content, a decrease in dropping point, a darker appearance, a peculiar smell, and a consistency and strength limit. The viscosity decreases, corrosive products and substances that destroy the grease structure are generated, causing soap oil separation. Oxidation stability is the main indicator for determining the stability of diesel, and it is also an important test item for diesel finished products leaving the factory. If the result is too large, it will cause excessive sludge in the centrifuge and filter, clogging the filter, polluting the injector, and causing poor combustion.

However, in actual use, it is inconvenient to install and disassemble the measuring tube and the heating tube, and it cannot play a good fixing role during the experiment, so the practicality is low. In view of the above problems, a device for measuring the oxidation stability of diesel is proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-4 The device for measuring the oxidation stability of diesel shown in the figure comprises an integrated housing 1, a cover plate 2, a measuring tube 8, and a heating tube 9. It should be noted that, in the present embodiment, the connection method of the measuring tube 8 and the heating tube 9 can refer to the technical content adopted in a device for measuring the oxidation stability of biodiesel disclosed in the Chinese patent with publication number CN218726852U in the prior art, which will not be described in detail here. A partition is fixedly installed on the bottom inner wall of the integrated housing 1, and both sides of the partition and the relative inner wall of the integrated housing 1 are slidably installed with a lifting plate 4, and the bottoms of the two lifting plates 4 are provided with a compression group Parts, two extrusion columns 6 are fixedly installed at the bottom of the cover plate 2, and the two extrusion columns 6 are respectively matched with the two lifting plates 4, and bases 5 are commonly installed on both sides of the two lifting plates 4. The tops of the two bases 5 are provided with placement grooves, and the measuring tube 8 and the heating tube 9 are respectively placed in the two placement grooves. The top of one of the bases 5 is provided with a heating resistance wire 10 matched with the heating tube 9, and the relative inner walls of the integrated housing 1 are provided with two sliding holes, and sliding shafts 11 are slidably installed in the four sliding holes. One end of the four sliding shafts 11 is provided with an arc clamping plate 12, and the four sliding shafts 11 are connected by a linkage component.

[0023] With the above structure, when in use, first place the measuring tube 8 and the heating tube 9 in the two placement grooves respectively, and then install the cover plate downward along the integrated shell 1. When the two extrusion columns 6 are in contact with the two lifting plates 4, the two lifting plates 4 and the two bases 5 are driven to move downward synchronously under the extrusion action, and the compression component is squeezed. After moving downward to a fixed position, the cover plate 2 is fixed, and then the four sliding shafts 11 are driven by the linkage component to move synchronously toward the heating tube 9 and the measuring tube 8, and the heating tube 9 and the measuring tube 8 are clamped and fixed by four arc-shaped clamping plates 12, so that they can be more stable during the experiment. After the experiment, remove the cover plate 2, and drive the base 5 to move upward under the elastic action of the compression component, so as to facilitate the removal of the measuring tube 8 and the heating tube 9.

[0024] like Figure 2As shown, the compression assembly includes two compression springs 3, one end of the two compression springs 3 is fixedly installed on the bottom of the lifting plate 4, and the other end of the two compression springs 3 is fixedly installed on the bottom inner wall of the integrated housing 1. The advantage of this arrangement is that through the elastic action of the two compression springs 3, when the squeezing action on the lifting plate 4 is released, the lifting plate 4 can be driven to achieve a reset function through its elastic action.

[0025] Specifically, when the cover plate 2 and the two extrusion columns 6 are pressed downward, the lifting plate 4 is driven downward under the action of pressure, and then the two bases 5 are driven to move downward synchronously to squeeze the compression spring 3. When the experiment is over, the squeezing effect on the lifting plate 4 is released, and the elastic action of the compression spring 3 can drive the lifting plate 4 and the base 5 to realize the reset function, so that the measuring tube 8 and the heating tube 9 can be removed easily.

[0026] like Figure 2 As shown, semicircular buffer pads 7 are fixedly installed on the inner walls of the two placement grooves. The advantage of this arrangement is that through the arrangement of the semicircular buffer pads 7, a protective function can be achieved when the measuring tube 8 or the heating tube 9 is placed.

[0027] Specifically, when the measuring tube 8 and the heating tube 9 are placed in the two placement grooves, the semicircular buffer pad 7 is provided, which can play a buffering role during placement, thereby improving the protection function of the measuring tube 8 and the heating tube 9.

[0028] like Figure 4 As shown, arc-shaped protection pads 13 are provided on the inner walls of the circumference of the four arc-shaped clamping plates 12. The advantage of such a configuration is that, by providing the arc-shaped protection pads 13 on the inner walls of the circumference of the arc-shaped clamping plates 12, a protective function can be played when clamping the measuring tube 8 and the heating tube 9.

[0029] Specifically, when the arc-shaped clamping plate 12 contacts the measuring tube 8 and the heating tube 9, the arc-shaped protective pad 13 is provided on the inner wall of the peripheral side, so that the outer wall of the peripheral side can be protected to prevent damage.

[0030] like Figure 4 As shown, the linkage assembly includes two connecting plates 14, and the two connecting plates 14 are respectively fixedly installed on the ends of the four sliding shafts 11. The relative inner walls of the integrated housing 1 are provided with mounting holes, and a bidirectional screw rod 15 is installed in the two mounting holes for common rotation. The two connecting plates 14 are both threadedly installed on the bidirectional screw rod 15, and a rotating unit is provided at one end of the bidirectional screw rod 15, and a limiting unit is provided at the other end of the bidirectional screw rod 15. The advantage of such a setting is that through the setting of the bidirectional screw rod 15, the two connecting plates 14 can be driven to move synchronously toward or away from each other.

[0031] Specifically, when the bidirectional screw 15 rotates, the two connecting plates 14 are driven to move toward or away from each other synchronously under the action of the thread, thereby driving the multiple sliding shafts 11 to move synchronously, so as to clamp and fix the measuring tube 8 and the heating tube 9.

[0032] like Figure 4 As shown, the rotating unit includes a knob 16 , and the end of the knob 16 is fixedly connected to the end of the bidirectional screw rod 15 . The advantage of such a setting is that the setting of the knob 16 makes it more convenient for the staff to rotate the bidirectional screw rod 15 .

[0033] Specifically, when the bidirectional screw rod 15 needs to be rotated, the bidirectional screw rod 15 can be driven to rotate synchronously by simply rotating the knob 16 .

[0034] like Figure 4 As shown, the limiting unit includes a limiting plate 17, and the end of the limiting plate 17 is fixedly connected to the end of the bidirectional screw rod 15. The advantage of this arrangement is that through the setting of the limiting plate 17, the limiting function of the connecting plate 4 can be achieved to prevent it from falling off.

[0035] Specifically, when the bidirectional screw rod 15 rotates, the connecting plate 14 moves horizontally through the action of the thread, and can be limited by the limiting plate 17 to prevent it from falling off the bidirectional screw rod 15 .

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
