Description

Technical Field

[0001] This utility model relates to the field of asphalt production technology, specifically to a heating tank structure applied to asphalt materials. Background Technology

[0002] As described in the published patent CN205760821U, "An Asphalt Heating and Mixing Device," asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementitious material. It is used in industries such as coatings, plastics, and rubber, as well as in road paving. At room temperature, asphalt is a black or dark brown viscous liquid, semi-solid, or solid. To liquefy it for construction, it often needs to be heated, especially in cold winters. Existing asphalt heating devices generally use heating oil or electric heating. Heating oil is achieved by placing heating oil in a pipe inside the asphalt container, allowing heat exchange to heat the asphalt. Electric heating primarily uses heating wires, which are wrapped around the outer wall of the asphalt container to heat the asphalt. The disadvantages are uneven heating; asphalt close to the heating device ages due to excessive heat, while asphalt further away remains unheated.

[0003] In summary, asphalt materials suffer from uneven heating during the heating process. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution for a heating tank structure applied to asphalt materials that can solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heating tank structure for asphalt materials includes a tank body, a top cover screwed to the upper end of the tank body, a feed hopper installed at the upper end of the top cover, a stirring mechanism and a heating assembly installed at the upper end of the top cover, a discharge pipe installed at the lower end of the tank body, and a gate valve installed on the outside of the discharge pipe.

[0007] The stirring mechanism includes a mounting plate installed on the top of the top cover. A drive motor is installed on the inner top of the mounting plate. A first gear is installed on the working shaft of the drive motor. A second gear meshes with the outer side of the first gear. A stirring tube is installed in the middle of the second gear. The stirring tube is rotatably connected to the top cover. An aeration component is provided at the lower end of the stirring tube. A stirring component is installed at the lower end of the aeration component.

[0008] The heating assembly includes a booster pump installed on the top of the top cover. An air inlet pipe is installed on one side of the booster pump, and an aeration pipe is connected to one side of the booster pump. One end of the aeration pipe is rotatably connected to the stirring pipe.

[0009] As a further embodiment of this utility model: the tank body includes an outer shell, an inner shell is connected to the inner cavity of the outer shell, and heating wires are installed at equal intervals between the inner shell and the outer shell.

[0010] As a further embodiment of this utility model: a conical cover is installed on the upper part of the inner cavity of the tank, a filter grid is connected to the bottom of the inner cavity of the conical cover, the stirring tube is rotatably connected to the middle of the filter grid, a crushing component is installed on the outside of the stirring tube, and the crushing component is disposed inside the conical cover.

[0011] As a further embodiment of this utility model: the crushing assembly includes three sets of first crushing blades fixedly installed on the outside of the stirring tube, and a second crushing blade is installed at the lower end of the first crushing blade.

[0012] As a further embodiment of this utility model: the aeration assembly includes a fixed plate fixedly installed on the outside of the stirring tube, a sealing cylinder movably sleeved on the lower outer side of the stirring tube, and a support plate fixedly connected to the upper end of the sealing cylinder.

[0013] The outer side of the sealing cylinder is provided with three vent holes at equal intervals. The inner cavity of each vent hole is connected to an L-shaped tube. The upper end of the support plate is symmetrically equipped with nail-shaped limiting posts. The upper end of each nail-shaped limiting post penetrates through the fixed plate and extends above the fixed plate. A spring is sleeved on the nail-shaped limiting post and elastically abuts against the upper end surface of the fixed plate.

[0014] As a further embodiment of this utility model: the stirring assembly includes a stirring shaft installed at the lower end of the sealing cylinder, and a stirrer is installed on the outside of the stirring shaft. The stirrer consists of multiple sets of horizontal bars and vertical bars, each set of horizontal bars being connected to the stirring shaft, and the vertical bars being connected between the horizontal bars.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. After being heated by the heating wire, the inner shell absorbs heat and transfers it to the asphalt inside the inner shell cavity, causing the asphalt to melt rapidly and effectively increasing the efficiency of asphalt heating. The pressurized hot air is discharged into the mixing tube by the booster pump, and the pressure of the hot air in the mixing tube increases rapidly, pushing the sealing cylinder and mixing component downward. When the vent on the outside of the sealing cylinder moves to the bottom of the mixing tube, the hot air in the mixing tube is discharged from the vent to the three L-shaped tubes, and the L-shaped tubes discharge hot air into the inner cavity of the inner shell. Subsequently, when the pressure of the hot air in the mixing tube is lower than the rebound pressure of the spring, the spring rebounds and resets, thereby driving the nail-shaped limit post, support plate, sealing cylinder and mixing component to move upward, which facilitates the mixing component to rotate and mix the asphalt at different heights. The aeration component is synchronized and automatic with the mixing tube, so that the three L-shaped tubes continuously and intermittently blow hot air into different heights of the inner shell cavity, further increasing the efficiency of asphalt mixing and heating, and effectively improving the use effect.

[0017] 2. The three sets of first crushing blades of the crushing component crush the lumps in the asphalt material. The crushed asphalt material falls through the filter grid after being filtered evenly. The asphalt material that is not crushed completely is crushed, stirred and cut by the second crushing blades until the material size can be filtered through the filter grid and fall into the inner cavity of the inner shell. By refining the semi-solid asphalt, the efficiency of heating and melting the asphalt is effectively improved. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-8 A heating tank structure for asphalt materials includes a tank body 1. A top cover 2 is screwed to the upper end of the tank body 1. A feed hopper 3 is installed on the upper end of the top cover 2. A discharge pipe 6 is installed at the lower end of the tank body 1. A gate valve 7 is installed on the outside of the discharge pipe 6. The tank body 1 includes an outer shell 11. An inner shell 12 is connected to the inner cavity of the outer shell 11. Heating wires 13 are installed at equal intervals between the inner shell 12 and the outer shell 11. The heating wires 13 are turned on by an external temperature controller and adjusted to a predetermined temperature for heating. The outer shell 11 is made of heat-insulating material, and the inner shell 12 is made of metal material. Thus, the heating wires 13 are installed close to the inner shell 12. The heat generated by the heating wires 13 is absorbed by the inner shell 12, and the inner shell 12 transfers the heat to the asphalt material inside the inner cavity of the inner shell 12, so that the asphalt material is heated and melted quickly, effectively increasing the heating efficiency of the asphalt material.

[0030] A stirring mechanism 4 and a heating assembly 5 are installed on the upper end of the top cover 2. The stirring mechanism 4 includes a mounting plate 41 installed on the upper end of the top cover 2. A drive motor 42 is installed on the inner top of the mounting plate 41. A first gear 43 is installed on the working shaft of the drive motor 42. A second gear 45 meshes with the outer side of the first gear 43. A stirring tube 44 is installed in the middle of the second gear 45. The stirring tube 44 is rotatably connected to the top cover 2. A conical cover 8 is installed on the upper part of the inner cavity of the tank body 1. A filter grid 9 is connected to the bottom of the inner cavity of the conical cover 8. The stirring tube 44 is rotatably connected to the middle of the filter grid 9. A pulverizing assembly 46 is installed on the outer side of the stirring tube 44. The pulverizing assembly 46 is located in the inner cavity of the conical cover 8. The pulverizing assembly 46 includes three sets of first pulverizing blades 461 fixedly installed on the outer side of the stirring tube 44. A second pulverizing blade 462 is installed at the lower end of one set of first pulverizing blades 461.

[0031] By pouring semi-solid asphalt from the feed hopper 3 into the inner cavity of the inner shell 12, the asphalt first enters the inner cavity of the conical cover 8. The drive motor 42 is turned on by an external control switch, and the output end of the drive motor 42 drives the first gear 43 to rotate. The first gear 43 drives the second gear 45 to rotate, and the second gear 45 simultaneously drives the stirring tube 44 and the crushing component 46 to rotate. The three sets of first crushing blades 461 of the crushing component 46 crush the lumps in the asphalt material. The crushed asphalt material falls through the filter grid 9 after being filtered. The asphalt material that is not completely crushed is further crushed, stirred and cut by the second crushing blades 462 until the material size can be filtered through the filter grid 9 and fall into the inner cavity of the inner shell 12. By refining the semi-solid asphalt, the efficiency of heating and melting the asphalt is effectively improved.

[0032] An aeration component 47 is provided at the lower end of the stirring tube 44, and a stirring component 48 is installed at the lower end of the aeration component 47. The stirring component 48 includes a stirring shaft 481 installed at the lower end of the sealing cylinder 471. An agitator 482 is installed on the outside of the stirring shaft 481. The agitator 482 consists of multiple sets of horizontal bars and vertical bars. Each set of horizontal bars is connected to the stirring shaft 481, and the vertical bars are connected between the horizontal bars.

[0033] The aeration component 47 and the agitation component 48 are driven to rotate synchronously by the stirring pipe 44. The horizontal and vertical rods in the agitator 482 of the agitator component 48 quickly stir the asphalt in the inner cavity of the inner shell 12, so that the agitator component 48 can stir the asphalt in both horizontal and vertical directions. This allows the asphalt to quickly and evenly absorb the heat generated by the heating wire 13, which makes it melt quickly and improves the stirring and heating effect.

[0034] The heating assembly 5 includes a booster pump 51 installed on the top of the top cover 2. An air inlet pipe 51 is installed on one side of the booster pump 51, and an aeration pipe 53 is connected to one side of the booster pump 51. One end of the aeration pipe 53 is rotatably connected to the stirring pipe 44 while ensuring the airtightness between the two. A rotary sealing device is provided between the inner wall of the aeration pipe 53 and the stirring pipe 44. In one embodiment, the rotary sealing device adopts the structure of the rotary sealing device and gas insulation switch disclosed in the patent with publication number CN206379669U.

[0035] The aeration assembly 47 includes a fixed plate 473 fixedly installed on the outside of the stirring tube 44, a sealing cylinder 471 movably sleeved on the outside of the lower end of the stirring tube 44, and a support plate 474 fixedly connected to the upper end of the sealing cylinder 471.

[0036] The outer side of the sealing cylinder 471 is provided with three vent holes 477 at equal intervals. The inner cavity of each vent hole 477 is connected to an L-shaped tube 472. The upper end of the support plate 474 is symmetrically equipped with nail-shaped limiting posts 475. The upper end of each nail-shaped limiting post 475 penetrates through the fixed plate 473 and extends above the fixed plate 473. A spring member 476 is sleeved on the nail-shaped limiting post 475 and elastically abuts against the upper end surface of the fixed plate 473.

[0037] The booster pump 51 is turned on by an external control switch, allowing preheated hot air to enter through the air inlet pipe 51. The hot air is then pressurized and discharged into the stirring tube 44 through the aeration pipe 53. As the pressure of the hot air in the stirring tube 44 rapidly increases, it pushes the sealing cylinder 471 downwards. The sealing cylinder 471 then moves the support plate 474 and the nail-shaped limiting post 475 downwards. The nail-shaped limiting post 475 compresses the spring 476 downwards, causing the sealing cylinder 471 to move downwards, simultaneously moving the stirring assembly 48 downwards. At the same time, when the vent hole 477 on the outside of the sealing cylinder 471 moves below the stirring tube 44, the hot air in the stirring tube 44 is discharged from the vent hole 477 to the three L-shaped pipes 472. The L-shaped pipes 472 then discharge hot air into the inner cavity of the inner shell 12. Subsequently, when the pressure of the hot air in the stirring tube 44... When the hot air pressure is lower than the rebound pressure of the spring element 476, the spring element 476 automatically rebounds and resets, thereby driving the nail-shaped limit post 475, the support plate 474, and the sealing cylinder 471 to move upward and reset. This causes the sealing cylinder 471 to drive the mixing component 48 to move upward, facilitating the mixing component 48 to mix asphalt at different heights, further increasing the effect of uniform heating of asphalt. The distances from the lower ends of the three L-shaped tubes 472 to the bottom of the inner cavity of the inner shell 12 are all different, and the distances from the three L-shaped tubes 472 to the sealing cylinder 471 in the horizontal direction are also different. The aeration component 47 is synchronized and automatic with the mixing tube 44, so that the three L-shaped tubes 472 continuously and intermittently blow hot air into different heights of the inner cavity of the inner shell 12, further increasing the efficiency of heating asphalt.

[0038] Working Principle: This invention uses an external temperature controller to activate the heating wire 13 and set it to a predetermined temperature for heating. The outer shell 11 is made of insulation material, while the inner shell 12 is made of metal. The heat generated by the heating wire 13 is absorbed by the inner shell 12, which then transfers the heat to the asphalt within its cavity, rapidly melting the asphalt and effectively increasing the heating efficiency. An external control switch activates the drive motor 42 and the booster pump 51. The output of the drive motor 42 drives the first gear 43, which in turn drives the second gear 45, which in turn synchronously drives the stirring tube. The mixing tube 44 and the crushing component 46 rotate. By changing the first gear 43 with different transmission ratios, the rotation speed of the mixing tube 44 can be easily and significantly adjusted. By crushing and refining the semi-solid asphalt material, the efficiency of heating and melting the asphalt is effectively improved. At the same time, the mixing tube 44 drives the aeration component 47 and the mixing component 48 to rotate synchronously. The booster pump 51 introduces preheated hot air at a predetermined temperature through the air inlet pipe 51, pressurizes it, and discharges it into the mixing tube 44 through the aeration pipe 53. When the pressure of the hot air in the mixing tube 44 increases rapidly, it pushes the sealing cylinder 471 downwards, and the sealing cylinder 471 drives the support plate 47. 4. The nail-shaped limiting post 475 moves downward, compressing the spring 476 downward. This causes the sealing cylinder 471 to move downward, simultaneously moving the stirring assembly 48 downward. At the same time, when the vent 477 on the outside of the sealing cylinder 471 moves below the stirring tube 44, hot air in the stirring tube 44 is discharged from the vent 477 to the three L-shaped tubes 472. The L-shaped tubes 472 then discharge hot air into the inner cavity of the inner shell 12. Subsequently, when the pressure of the hot air in the stirring tube 44 is lower than the rebound pressure of the spring 476, the spring 476 automatically rebounds and resets, thereby causing the nail-shaped limiting post 475, the support plate 474, and the sealing cylinder 471 to move upward and reset. The sealing cylinder 471 drives the mixing component 48 to move upward, which facilitates the mixing component 48 to rotate and mix the asphalt at different heights, further increasing the effect of uniform heating of the asphalt. The distances from the lower ends of the three L-shaped pipes 472 to the bottom of the inner cavity of the inner shell 12 are all different, and the distances from the sealing cylinder 471 of the three L-shaped pipes 472 in the horizontal direction are also different. The aeration component 47 is synchronized and automatic with the mixing pipe 44, so that the three L-shaped pipes 472 continuously and intermittently blow hot air into the inner cavity of the inner shell 12 at different heights, further increasing the efficiency of heating the asphalt and effectively improving the use effect.
