Description

Technical Field

[0001] This utility model relates to the field of asphalt processing technology, specifically to an anti-adhesion asphalt mixing tank. Background Technology

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a type of high-viscosity organic liquid, mostly existing in liquid or semi-solid petroleum form. It has a black surface and is soluble in carbon disulfide and carbon tetrachloride. When processing asphalt for construction, an anti-sticking asphalt batching tank is required.

[0003] Currently, in the production of asphalt, the viscosity of asphalt is related to the ratio of asphalt raw materials, so it is necessary to strictly control the ratio of asphalt raw materials. Traditionally, the asphalt raw material ratio is controlled by manual weighing by staff, which is time-consuming and labor-intensive, reducing the production efficiency and effectiveness of asphalt. Furthermore, during the asphalt production process, asphalt adheres to the inner wall of the tank. If the asphalt on the inner wall of the tank is not cleaned, it will lead to a large amount of asphalt waste, which will affect the production quality of asphalt and reduce the overall practicality of the batching tank.

[0004] Based on this, an anti-adhesion asphalt mixing tank is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] In one embodiment, such as Figures 1-8 As shown, an anti-adhesion asphalt construction mixing tank includes a base 1, a cylinder 2 located directly above the base 1, a closed cover 3 covering the outside of the cylinder 2, a support frame 4 fixedly connected to the upper surface of the base 1, and feed cylinders 5 symmetrically installed on the upper surface of the support frame 4. The bottom of the feed cylinder 5 is connected to the upper surface of the closed cover 3 through a first solenoid valve 6 and a bellows 7. The bottom of the cylinder 2 is connected to a discharge pipe 15 through a second solenoid valve 14.

[0037] A proportioning component is installed on the outer wall of cylinder 2 and is used to proportion different raw materials.

[0038] The reset assembly is symmetrically arranged on the upper surface of the base 1 and is used to reset the cylinder 2.

[0039] A mixing component is disposed in the middle of the upper surface of the closed cover 3 and is used to mix the raw materials inside the cylinder 2;

[0040] A cleaning component is disposed on the upper surface of the base 1 and is used to clean the asphalt on the inner wall of the cylinder 2.

[0041] In this embodiment, when asphalt needs to be processed, different raw materials are first added to two feed cylinders 5. At this time, the first solenoid valve 6 at the bottom of one feed cylinder 5 opens, and the asphalt raw material is transmitted to the inside of the cylinder 2 through the bellows 7. When the asphalt raw material enters the inside of the cylinder 2, it causes the cylinder 2 to shift downward. At this time, the proportioning component can effectively weigh one of the asphalt raw materials. When the weight of one of the asphalt raw materials reaches the specified standard, the proportioning component transmits a signal to the controller. The controller then controls the first solenoid valve 6 at the bottom of one feed cylinder 5 to close and controls the first solenoid valve 6 at the bottom of the other feed cylinder 5 to open. At this time, another asphalt raw material is added to the inside of the cylinder 2. The proportioning component can weigh the asphalt raw material again. When the weight of the other raw material reaches the specified proportioning standard, the proportioning component... The signal is transmitted to the controller, which then controls the first solenoid valve 6 at the bottom of another feed cylinder 5 to close. At this time, different asphalt raw materials can be conveniently and effectively proportioned without manual operation. When the asphalt raw materials are added into the cylinder 2, the mixing component starts to operate. At this time, the mixing component can effectively mix and stir the asphalt raw materials (during the asphalt raw material mixing process, the electric heating tube 17 will continuously heat and melt the asphalt raw materials), thereby effectively producing asphalt. During the asphalt raw material mixing process, the cleaning component will also start to operate simultaneously. At this time, the cleaning component can effectively blow off the asphalt on the inner wall of the cylinder 2, thereby effectively reducing the waste of asphalt. The reset component allows the staff to reuse the whole device, effectively improving the overall practicality of the device.

[0042] In one embodiment, such as Figure 3 As shown, a heating chamber 16 is provided inside the cylinder 2. An electric heating tube 17 is fixedly installed on the inner wall of the heating chamber 16. A temperature display 13 is fixedly connected to the surface of the cylinder 2. The temperature display 13 and the electric heating tube 17 are electrically connected through wires. When asphalt needs to be produced, the electric heating tube 17 starts to operate. At this time, the electric heating tube 17 can effectively heat and melt the asphalt raw materials, thereby effectively producing asphalt. The operator can check the temperature of the electric heating tube 17 through the temperature display 13.

[0043] In one embodiment, such as Figure 2 and Figure 6As shown, the outer wall of the closed cover 3 is symmetrically provided with insert plates 25, and the outer wall of the cylinder 2 is symmetrically provided with connecting frames 26. A fixing block 27 is fixedly connected to the surface of the connecting frame 26. A fixing rod 28 is provided inside the fixing block 27. A pull plate is fixedly connected to one end of the fixing rod 28. An abutment plate 29 is fixedly connected to the outer wall of the fixing rod 28. A return spring 30 is sleeved on the outside of the fixing rod 28. The return spring 30 abuts between the abutment plate 29 and the fixing block 27. Slots for the fixing rod 28 to move are provided on the contact surfaces of the fixing block 27 and the connecting frame 26, as well as on the surface of the insert plate 25. When it is necessary to fix the closed cover 3 to the cylinder 2, simply pull the pull plate 26. When the plate is pulled, the fixing rod 28 and the contact plate 29 will move synchronously. During the movement of the contact plate 29, the return spring 30 will be squeezed. Then, the closing cover 3 is placed on the outer wall of the cylinder 2. The closing cover 3 will drive the insert plate 25 to be inserted into the inside of the connecting frame 26. Then, the plate is released, the return spring 30 returns to its original position, and the contact plate 29 and the fixing rod 28 move synchronously. When the fixing rod 28 is inserted into the slot on the surface of the insert plate 25, the closing cover 3 and the cylinder 2 can be fixed together. At the same time, it is convenient for the staff to open the closing cover 3, so that the staff can clean the inside of the cylinder 2.

[0044] In one embodiment, such as Figures 1-3 As shown, the proportioning component includes a fixing ring 8 fixedly connected to the outer wall of the cylinder 2. The outer wall of the fixing ring 8 is symmetrically provided with outer plates 9. The bottom of each outer plate 9 is fixedly connected to a lower pressure plate 11 through a base plate 10. A weighing sensor 12 is provided directly below the lower pressure plate 11. The bottom of the weighing sensor 12 is fixedly connected to the upper surface of the base 1. When it is necessary to proportion the asphalt raw materials, the raw materials are simply added into the cylinder 2. When the raw materials enter the cylinder 2, the weight of the raw materials will cause the cylinder 2 to move downward. At this time, the cylinder 2 will drive the fixing ring 8 and the outer plates 9 to move synchronously. The outer plates 9 will then drive the lower pressure plate 11 to move synchronously. When the bottom of the lower pressure plate 11 touches the upper surface of the weighing sensor 12, the raw materials inside the cylinder 2 can be weighed by the weighing sensor 12, thereby effectively proportioning the raw materials without the need for manual operation (the weighing sensor 12 has a pressure compensation function).

[0045] In one embodiment, such as Figure 5 and Figure 8As shown, the reset assembly includes an adjusting plate 34 symmetrically arranged on the upper surface of the base 1. A slide rod 35 is fixedly connected to the inner wall of the adjusting plate 34, and sliders 36 are symmetrically arranged on the outer wall of the slide rod 35. A guide groove for the sliders 36 to move is opened on the upper surface of the adjusting plate 34. A hinge block 39 is hinged to the upper surface of each pair of sliders 36 through a connecting rod 38. A connecting spring 37 is sleeved on the outside of the slide rod 35. The two ends of the connecting spring 37 are fixedly connected to the opposite side of each pair of sliders 36. A damping rod 40 is fixedly connected to the middle of the upper surface of the adjusting plate 34. The telescopic end of the damping rod 40 is fixedly connected to the bottom of the hinge block 39. A connecting frame 24 is fixedly connected to the bottom of the outer plate 9. The bottom of the connecting frame 24 is fixedly connected to the upper surface of the hinge block 39. During the downward movement, the outer plate 9 and the connecting frame 24 will also move synchronously. The connecting frame 24 will then drive the hinge block 39 to move synchronously downward. Since the slider 36 and the hinge block 39 are hinged together by the connecting rod 38, the hinge block 39 will drive the slider 36 to move synchronously on the outer wall of the slider 35 through the connecting rod 38. During the movement of the slider 36, the connecting spring 37 will be stretched. When the asphalt inside the cylinder 2 is completely discharged, the connecting spring 37 will return to its original position, thereby driving the slider 36 to move synchronously to its original position, and then driving the cylinder 2 to move synchronously to its original position. At this time, it is convenient for the staff to reuse the whole device (the elastic coefficient of the connecting spring 37 is less than or equal to 10N / mm).

[0046] In one embodiment, such as Figure 3 and Figure 7 As shown, the mixing assembly includes a drive motor 21 fixedly connected to the upper surface of the closed cover 3. The output shaft of the drive motor 21 is fixedly connected to a rotating rod 31 via a coupling. Multiple stirring blades 32 are fixedly installed on the outer wall of the rotating rod 31, and multiple scrapers 33 are fixedly connected to the outer wall of the rotating rod 31. When it is necessary to mix the asphalt raw materials, the drive motor 21 starts to run. At this time, the drive motor 21 will drive the rotating rod 31 and the stirring blades 32 to rotate synchronously, so that the asphalt raw materials can be effectively mixed and stirred by the stirring blades 32. During the rotation of the rotating rod 31, the scrapers 33 will also rotate synchronously. At this time, the scrapers 33 can effectively scrape off the asphalt adhering to the inner wall of the cylinder 2, thereby reducing the probability of asphalt waste.

[0047] In one embodiment, such as Figures 1-5As shown, the cleaning assembly includes a nitrogen generator 41 fixedly installed on the upper surface of the base 1. An annular pipe 20 is fixedly connected to the upper surface of the closed cover 3. Multiple air outlets 18 are connected to the bottom of the annular pipe 20. The nitrogen generator 41 and the annular pipe 20 are connected through a transmission pipe 19. During the asphalt production process, the nitrogen generator 41 will also start running synchronously. At this time, the nitrogen generator 41 will transmit nitrogen gas to the inside of the annular pipe 20 every thirty seconds (0.5MPa nitrogen gas is injected every thirty seconds), and then discharge it through the air outlets 18 (the air outlets of the air outlets 18 face the inner wall of the cylinder 2). At this time, the nitrogen gas can be used to impact and blow off the asphalt adhering to the inner wall of the cylinder 2, thereby further avoiding the probability of asphalt waste.

[0048] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, multiple guide rods 22 are fixedly connected to the upper surface of the base 1. Each guide rod 22 has a limiting plate 23 fixedly connected to its top end. Both connecting frames 24 have sliding grooves inside for the guide rods 22 to move. During the movement of the connecting frame 24, the guide rods 22 can effectively play a limiting and guiding role, thereby effectively improving the stability of the connecting frame 24 and the cylinder 2 during the movement.

[0049] The above embodiment discloses an anti-adhesion asphalt mixing tank. When asphalt needs to be processed, different raw materials are first added to two feed cylinders 5. At this time, the first solenoid valve 6 at the bottom of one feed cylinder 5 opens, and the asphalt raw material is transferred to the inside of the cylinder 2 through the bellows 7. When the asphalt raw material enters the cylinder 2, it causes the cylinder 2 to shift downwards. At this time, the weighing sensor 12 can effectively weigh one type of asphalt raw material. When the weight of one type of asphalt raw material reaches the specified standard, the weighing sensor 12 transmits a signal to the controller. The controller then controls the first solenoid valve 6 at the bottom of one feed cylinder 5 to close and controls the first solenoid valve 6 at the bottom of the other feed cylinder 5 to open. At this time, another type of asphalt raw material is added to the inside of the cylinder 2. The weighing sensor 12 can then weigh the asphalt raw material again. When the weight of the other raw material reaches the specified proportion standard, the weighing sensor 12... The signal is transmitted to the controller, which then controls the first solenoid valve 6 at the bottom of the other feed cylinder 5 to close. At this time, different asphalt raw materials can be mixed conveniently and effectively without manual operation. When the asphalt raw materials are added into the cylinder 2, the drive motor 21 starts to run. At this time, the drive motor 21 can drive the stirring fan blades 32 and scraper 33 to rotate synchronously, thereby effectively mixing and stirring the asphalt raw materials (during the asphalt raw material mixing process, the electric heating tube 17 will continuously heat and melt the asphalt raw materials), thus effectively producing asphalt. During the asphalt raw material mixing process, the nitrogen generator 41 will also start to run synchronously. At this time, the nitrogen generator 41 can effectively spray nitrogen gas through the gas outlet 18 onto the inner wall of the cylinder 2, thereby effectively blowing off the asphalt on the inner wall of the cylinder 2, thus effectively reducing asphalt waste and effectively improving the overall practicality of the device.
