Description

Technical Field

[0001] This utility model relates to the field of asphalt testing technology, and specifically to an asphalt heating test device. Background Technology

[0002] Asphalt, as an important petrochemical product, is widely used in road construction, waterproofing projects, and other fields. Asphaltenes are an important component of asphalt, and their content and properties directly affect the performance of asphalt. Therefore, accurate analysis and testing of asphaltenes are crucial. Traditional asphaltenes heating test apparatus usually uses electric heating mantles or oil bath heating methods, which have problems such as uneven heating, low temperature control accuracy, and cumbersome operation. In addition, it is difficult to ensure precise alignment between the conical flask and the heating unit, affecting the accuracy of the test results.

[0003] In recent years, electric heating technology has been gradually applied to the field of laboratory heating. Electric heating panels have advantages such as fast heating speed, high thermal efficiency, and precise temperature control, and can be applied to conical flasks of different sizes. However, existing electric heating devices are mostly designed for single containers, which makes it difficult to meet the needs of heating multiple samples simultaneously in asphalt heating tests. Uneven heating within the same group often leads to poor parallelism of results. In addition, how to achieve precise positioning between multiple conical flasks and the heating panel and stable clamping of the condenser tube are still problems that need to be solved. In the existing technology, Chinese patent CN215678189U discloses a water-saving petroleum product moisture distillation analyzer. However, in this patent, the distillation flask is fixed by the heating base, lacking elastic adjustment function, making it difficult to adapt to distillation flasks of different sizes. Moreover, the condenser tube is fixed through the hole on the support base, lacking height adjustment function, which makes it inconvenient for testers to operate. Utility Model Content

[0004] This invention provides an asphalt heating test device, which significantly improves experimental accuracy and ease of operation through its flexible bottle clamp design, precise positioning and centering, and convenient height adjustment function. It is highly efficient and flexible overall and suitable for a variety of experimental scenarios.

[0005] To achieve these objectives and other advantages of this utility model, an asphalt heating test device is provided, comprising: an electric heating device with a plurality of heating panels for heating conical flasks; a positioning plate disposed on the electric heating device, the positioning plate having pre-reserved openings corresponding one-to-one with the heating panels; a plurality of bottle clamps, each bottle clamp corresponding one-to-one with the pre-reserved openings, each bottle clamp including a plurality of arc-shaped springs arranged in a circle around the edge of the pre-reserved opening, each arc-shaped spring being S-shaped, with a flat bottom connected to the positioning plate, and the top of each arc-shaped spring bending outward into a hook shape, the tops of the plurality of arc-shaped springs arranged in a circle sharing an elastic ring; a support frame with tube clamps corresponding to the pre-reserved openings, each tube clamp holding a condenser tube, wherein the corresponding heating panels, pre-reserved openings, elastic rings, and condenser tubes are coaxial; and a plurality of columns disposed on both sides of the electric heating device, the support frame being connected to the columns.

[0006] Preferably, the electric heating device has several supporting columns facing upwards, and the positioning plate has several fixing plates facing downwards corresponding to the positions of the supporting columns. The fixing plates are bolted to the corresponding supporting columns, and the positioning plate is flush with the top surface of the heating panel.

[0007] Preferably, the bottom straight section of the arc-shaped spring is bolted to the positioning plate.

[0008] Preferably, the electric heating device has a column on each side. The column includes a base, a limiting cylinder shell, and a limiting top block connected sequentially from bottom to top. A lead screw is installed inside the limiting cylinder shell. The two ends of the lead screw are rotatably connected to the base and the limiting top block, respectively. A slider with a shape matching the inner wall of the limiting cylinder shell is sleeved on the lead screw. Each of the two limiting cylinder shells has a vertical groove on opposite sides. The two sliders are at the same height and are respectively connected to the two ends of a connecting beam. The connecting beam passes through the two vertical grooves and is connected to the support frame.

[0009] Preferably, the base is a shell structure, in which a horizontal bevel gear and a vertical bevel gear mesh with each other are provided. The bottom end of the lead screw extends into the base and is coaxially connected with the horizontal bevel gear. The two vertical bevel gears are coaxial and share a horizontal shaft at their center. One end of the horizontal shaft extends out of the base on the corresponding side.

[0010] Preferably, a hand crank is fixedly connected to the extended end of the horizontal shaft.

[0011] Preferably, the elastic coil is a stainless steel spring.

[0012] Preferably, the arc-shaped spring is made of stainless steel.

[0013] This utility model has at least the following beneficial effects:

[0014] First, this utility model adopts an S-shaped arc-shaped spring sheet and elastic ring structure, which can flexibly adapt to conical flasks of different specifications. The bottom of the arc-shaped spring sheet is flat and connected to the positioning plate, and the top is bent outward into a hook shape and fixed by the elastic ring. The bottle clamp forms a uniform clamping force on the conical flask placed inside, which can firmly fix the conical flask and avoid uneven heating of the bottle body due to eccentricity. In addition, this device is adaptable to conical flasks of different diameters, and the device has good versatility and experimental flexibility.

[0015] Secondly, the design of the positioning plate, reserved opening and support frame ensures that the conical flask, heating panel and condenser tube are on the same axis, avoiding the problem of uneven heating caused by inaccurate centering of the conical flask, and improving the accuracy and reliability of the experimental results.

[0016] Third, this utility model uses columns, lead screws and sliders to smoothly raise and lower the support frame, making it easy to flexibly adjust the relative position between the condenser tube and the conical flask, and the operation is simple.

[0017] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0028] like Figure 1-6As shown, the technical solution of this application provides an asphalt heating test device, including an electric heating device 1, on which a plurality of heating panels 11 are provided for heating conical flasks 6; a positioning plate 2, which is disposed on the electric heating device 1, the positioning plate 2 having reserved openings 20 corresponding one-to-one with the heating panels 11; a plurality of bottle clamps 3, the bottle clamps 3 corresponding one-to-one with the reserved openings 20, the bottle clamps 3 including a plurality of arc-shaped spring pieces 31, the plurality of arc-shaped spring pieces 31 being arranged around the periphery of the reserved openings 20, the arc-shaped spring pieces 31... It is S-shaped, with a flat bottom and connected to the positioning plate 2. The top of the arc-shaped spring piece 3 is bent outward into a hook shape. Several arc-shaped spring pieces 31 arranged in a circle share an elastic ring 32 at their tops. The support frame 4 is provided with a pipe clamp 41 corresponding to the reserved opening 20. Each pipe clamp 41 holds a condenser pipe 7. The corresponding heating panel 11, reserved opening 20, elastic ring 32, and condenser pipe 7 are coaxial. Several columns 5 are provided on both sides of the electric heating device 1. The support frame 4 is connected to the columns 5. In this technical solution, the electric heating device 1 adopts a multi-head ceramic electric heating plate heating device that is readily available or easily manufactured in the market. The electric heating device 1 is equipped with multiple pairs of heating panels 11. The heating panels 11 are circular and have resistance wires embedded below. The heating panels 11 generate heat through the resistance effect. The conical flask 6 containing the asphalt sample is placed on the heating panel 11. The asphalt in the conical flask 6 gradually heats up after being heated and reaches its boiling point, thereby realizing the testing process such as heating, dissolving or distilling.

[0029] In this technical solution, the positioning plate 2 is a horizontally placed plate or frame. The positioning plate 2 is installed on the base of the electric heating device 1 by means of a fixing piece or other structure. The positioning plate 2 has a reserved opening 20 corresponding to each heating panel 11. The positioning plate 2 is flush with the heating panel 11 or there is a certain height difference to avoid the positioning plate 2 being directly heated. A bottle clamp 3 is installed on each reserved opening 20. The bottle clamp 3 is composed of four arc-shaped spring pieces 31. The four arc-shaped spring pieces 31 are arranged in a cross shape on the reserved opening. On the port 20, the upper ends of the four arc-shaped spring pieces 31 are all fitted with an elastic ring 32 for resetting the arc-shaped spring pieces 31 after deformation. When the tester places the conical bottle 6 on the heating panel 11 from top to bottom, the bottom of the conical bottle 6 first opens the four arc-shaped spring pieces 31, and then the four arc-shaped spring pieces 31 are pressed back against the bottle wall of the conical bottle 6 by the action of the elastic ring 32. Under the action of the arc-shaped spring pieces 31, the conical bottle 6 is located in the center of the heating panel 11, ensuring that the heating effect of each group of conical bottles 6 is the same.

[0030] In this technical solution, the support frame 4 is set above the electric heating device 1 by the column 5. The support frame 4 is provided with a pipe clamp 41 corresponding to the reserved opening 20 for fixing the condenser 7. During the test, the condenser 7 is firmly clamped above the corresponding conical flask 6, and there is no risk of tipping over.

[0031] In another technical solution, the electric heating device 1 is provided with several support columns 12 facing upwards, and the positioning plate 2 is provided with several fixing pieces 21 corresponding to the positions of the support columns 12 facing downwards. The fixing pieces 21 are bolted to the corresponding support columns 12. Each of the four corners of the electric heating device 1 is fixed upwards with a support column 12. The bottom surface of the positioning plate 2 is provided with four fixing pieces 21 corresponding to the positions of the support columns 12. The support columns 12 and the fixing pieces 21 are matched with through holes for bolts to pass through and complete the fixation.

[0032] In another technical solution, the bottom straight section of the arc-shaped spring piece 31 is bolted to the positioning plate 2. The positioning plate 2 has several mounting holes 200 around the reserved opening 20, and the bottom surface of the arc-shaped spring piece 31 has corresponding spring piece through holes 310 of the same size and position. The arc-shaped spring piece 31 is fixed to the positioning plate 2 by screws.

[0033] In another technical solution, the electric heating device 1 has a column 5 on each side. Each column 5 includes a base 50, a limiting cylinder 54, and a limiting top block 55 connected sequentially from bottom to top. A lead screw 53 is installed inside the limiting cylinder 54, with its two ends rotatably connected to the base 50 and the limiting top block 55, respectively. A slider 56, whose shape matches the inner wall of the limiting cylinder 54, is fitted onto the lead screw 53. Each of the two limiting cylinders 54 has a vertical groove 540 facing each other. The two sliders 56 are at the same height and are connected to the two ends of a connecting beam 57. The connecting beam 57 passes through the two vertical grooves 540 and is connected to the support frame 4. In this technical solution, the base 50 is fixed to the electric heating device. On both sides of 1, the upper and lower ends of the lead screw 53 are respectively connected to the limiting top block 55 and the base 50 by bearings. The slider 56 is a ball bearing with a thread that can rotate around the lead screw 53. The shape of the slider 56 matches the inner wall of the limiting cylinder shell 54. When the lead screw 53 rotates, the slider 56 moves up or down along the lead screw 53 under the action of the limiting cylinder shell 54. The connecting beam 57 passes between two opposite vertical grooves 540. When the two lead screws 53 rotate synchronously, the two sliders 56 and the connecting beam 57 and the support frame 4 on them move horizontally up and down, so as to achieve precise control of the position of the condenser tube 7. Optionally, the end of the lead screw 53 can be connected to a servo motor or other device to complete the rotation of the lead screw 53.

[0034] In another technical solution, the base 50 is a shell structure, in which a horizontal bevel gear 531 and a vertical bevel gear 511 mesh with each other are provided. The bottom end of the lead screw 53 extends into the base 50 and is coaxially connected with the horizontal bevel gear 531. The two vertical bevel gears 511 are coaxial and share a common horizontal shaft 51 at their axis. One end of the horizontal shaft 51 extends out of the corresponding side of the base 50. In this technical solution, the bottom of the lead screw 53 extends into the base 50, and the lead screw 53 and the top of the base 50 are rotatably connected by a first bearing 501 provided on the base 50. The horizontal shaft 51 and the base 50 are rotatably connected by a second bearing 502 provided on the base 50. When the horizontal shaft 51 rotates, it drives the two vertical bevel gears 511 to rotate, and the two meshing horizontal bevel gears 531 rotate simultaneously, driving the two lead screws 53 to rotate synchronously. The two sliders 56 achieve the effect of rising and falling together.

[0035] In another technical solution, the extended end of the horizontal shaft 51 is fixedly connected to a hand crank 52, which makes it convenient for the user to manually raise and lower the support frame 4.

[0036] In another technical solution, the elastic ring 32 is a stainless steel spring to avoid rusting caused by long-term contact with condensation.

[0037] In another technical solution, the arc-shaped spring 31 is made of stainless steel to avoid rusting due to long-term contact with condensation.
