Description

Technical Field

[0001] The utility model relates to the technical field of asphalt production equipment, in particular to asphalt heating equipment with the interior of which is easy to clean. Background Art

[0002] Asphalt is a dark brown complex mixture of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is liquid with a black surface and is soluble in carbon disulfide. Asphalt is an organic gelling material that is waterproof, moisture-proof and corrosion-resistant.

[0003] The patent (CN202223284106.8) discloses an asphalt heating device, which relates to the field of asphalt use technology, including an outer barrel, a main rod and an exhaust gas treatment mechanism. An inner barrel is arranged inside the outer barrel, and heating pipes are distributed between the outer barrel and the inner barrel. The main rod is located inside the inner barrel, and a spiral sheet is wound around the outer surface of the main rod. A motor is installed at the upper end of the main rod, and a second bearing is sleeved on the outer side of the lower end of the main rod. A plug rod is welded on the lower surface of the main rod. A control panel is arranged on the front surface of the outer barrel, and the exhaust gas treatment mechanism is located above the support plate. The utility model is provided with a main rod, a spiral sheet and a motor. The motor drives the main rod to rotate through the output shaft, and the spiral sheet located on the outer side of the main rod rotates accordingly. When the spiral sheet rotates, the asphalt can be stirred to facilitate the asphalt to be fully heated. In addition, when the spiral sheet stirs the asphalt, it will produce a downward squeezing force on the asphalt, forcing the asphalt to move to the discharge pipe, which is convenient for the discharge of the asphalt.

[0004] After the production of the asphalt heating device in the above patent document is completed, a part of asphalt will remain on the inner wall of the equipment. This part of asphalt needs to be cleaned in time to prevent it from affecting the production during the next use. However, in actual use, it is found that the product of the above patent technology needs to be cleaned manually for the remaining asphalt. When the asphalt is cooled, it is difficult to clean the asphalt, which reduces the work efficiency of the staff and reduces the production efficiency. Utility Model Content

[0023] Reference Figure 2-4 As shown, the cleaning mechanism 7 includes a first ball screw 73 and a second ball screw 74 which are rotatably connected to the inner wall of the tank body 3. The surfaces of the first ball screw 73 and the second ball screw 74 are movably matched and connected with the same cleaning ring 76. A scraper 77 is provided on the side of the cleaning ring 76 close to the inner wall of the tank body 3. A plurality of nozzles 78 are equidistantly provided at the bottom end of the cleaning ring 76. The top of the cleaning ring 76 is fixedly connected to the water pipe 6. A winding member 79 for retracting and releasing the water pipe 6 is provided at the top of the tank body 3. A driving member 75 for providing power to the cleaning ring 76 is provided inside and outside the tank body 3. The interior of the cleaning ring 76 is hollow. The hollow interior of the cleaning ring 76 is designed to be connected to the nozzle 78, and water can be sprayed out through the nozzle 78 to rinse the inner wall of the tank body 3.

[0024] When the equipment is being cleaned, the external water pump 4 starts to deliver water to the cleaning ring 76, and the water flushes the inner wall of the tank body 3 through the nozzle 78 below the cleaning ring 76. At the same time, the driving member 75 drives the first ball screw 73 and the second ball screw 74 to rotate, and the cleaning ring 76 moves up and down driven by the first ball screw 73 and the second ball screw 74. At this time, the nozzle 78 cleans the inner wall of the tank body 3 as a whole, and the scraper 77 on the cleaning ring 76 can perform secondary cleaning on the inner wall of the tank body 3, effectively cleaning the stubborn asphalt on the inner wall of the tank body 3.

[0025] The driving member 75 includes a second motor 70 arranged at the bottom of the tank body 3. The output end of the second motor 70 passes through the tank body 3 and extends to the inside of the tank body 3. The output end surface of the second motor 70 is provided with a first belt 71 and a second belt 72. The first belt 71 and the second belt 72 are respectively connected to the first ball screw 73 and the second ball screw 74 at one end away from the second motor 70. The second ball screw 74 extends to the outside of the tank body 3 at one end away from the second belt 72.

[0026] The winding member 79 includes a support frame 710 and a fixing frame 715 fixedly connected to the top of the tank body 3. The support frame 710 and the fixing frame 715 are rotatably connected to the first transmission shaft 711 and the second transmission shaft 712 respectively. The first transmission shaft 711 is connected to the second transmission shaft 712 through a first bevel gear set 716, and the second transmission shaft 712 is connected to the second ball screw 74 through a second bevel gear set 713. The water pipe 6 passes through the support frame 710 away from the side of the second transmission shaft 712 and extends to the first transmission shaft Inside 711, the first transmission shaft 711 is hollow, and a fixed block 714 is fixedly connected to the surface of one end of the first transmission shaft 711 away from the second transmission shaft 712. The surface of the fixed block 714 is fixedly connected to the water pipe 6. The water pipe 6 passes through the support frame 710 and extends to the inside of the first transmission shaft 711. The water pipe 6 then passes through the fixed block 714 from the inside of the first transmission shaft 711 and surrounds the surface of the first transmission shaft 711. The function of the fixed block 714 is to fix the water pipe 6 at the terminal position of the first transmission shaft 711.

[0027] When the equipment is working, because the first transmission shaft 711 is connected to the second transmission shaft 712 through the first bevel gear set 716, and the second transmission shaft 712 is connected to the second ball screw 74 through the second bevel gear set 713, when the second ball screw 74 rotates, it drives the first transmission shaft 711 to rotate, thereby releasing the water pipe 6 wrapped around the first transmission shaft 711. Therefore, when the cleaning ring 76 moves downward, the water pipe 6 will not be torn off due to insufficient length. Similarly, when the cleaning ring 76 finishes work and moves upward, the first transmission shaft 711 rotates in the opposite direction under the action of the second ball screw 74 to collect the water pipe 6.

[0028] The working principle and use process of this device are as follows: when the equipment is being cleaned, the external water pump 4 starts to deliver water to the cleaning ring 76, and the water flushes the inner wall of the tank body 3 through the nozzle 78 below the cleaning ring 76. At the same time, the second motor 70 is started, and the output end of the second motor 70 drives the first belt 71 and the second belt 72, thereby driving the first ball screw 73 and the second ball screw 74 to rotate. The cleaning ring 76 moves up and down driven by the first ball screw 73 and the second ball screw 74, and can clean the inner wall of the tank body 3 as a whole. At the same time, the scraper 77 on the cleaning ring 76 can perform secondary cleaning on the inner wall of the tank body 3, effectively cleaning the stubborn asphalt on the inner wall of the tank body 3. At the same time, the winding member 79 cooperates with the retracting and releasing action of the cleaning ring 76 to descend and rise to prevent the water pipe 6 from being damaged due to force.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
