DETAILED DESCRIPTION

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] Please also refer to Figures 1 to 7 Now, an asphalt melting tank provided by the utility model is described. The asphalt melting tank comprises a tank body 1, a hopper 2 and a sealing plate 3; the top of the tank body 1 is provided with a feed port; the top of the hopper 2 is provided with an opening; the bottom of the hopper 2 is connected to the feed port, and the side wall of the hopper 2 near the feed port is provided with a slide groove; the sealing plate 3 slides in cooperation with the slide groove; the tank body 1 is provided with a driving component 4 for driving the sealing plate 3 to slide; wherein, a vibrator (not shown in the figure) is provided on the outer wall of the hopper 2, and the vibrator is a prior art and will not be described here; the side wall of the hopper 2 is provided with a discharge port 21, and the outer wall of the hopper 2 is provided with a material receiving bag 5 at the position of the discharge port 21; the tank body 1 is provided with a lifting mechanism 6 for lifting the overhanging side of the material receiving bag 5. The material receiving bag 5 is flexible.

[0034] The utility model provides an asphalt melting tank. Compared with the prior art, the sealing plate 3 seals the outlet of the hopper 2, and the admixture is transported into the hopper 2 by a screw conveyor. After the loading is completed, the vibrator provides vibration force to the hopper 2, so that the material in the hopper 2 is more evenly distributed. During the vibration process, the material with a height exceeding the discharge port 21 will enter the discharge port 21 and eventually enter the receiving bag 5. After the vibration is completed, the sealing plate 3 is opened, and the material in the hopper 2 can fall into the tank body 1. The above arrangement can improve the accuracy of adding materials. In addition, when the material is loaded next time, the sealing plate 3 first seals the outlet of the hopper 2. During the process of the screw conveyor transporting the material into the hopper 2, the overhanging side of the receiving bag 5 moves upward under the action of the lifting mechanism 6, thereby causing the material in the receiving bag 5 to fall into the hopper 2.

[0035] It should be noted that a rotating stirring shaft is provided inside the tank body 1, which is equipped with a plurality of stirring blades. A stirring motor is provided at the top of the tank body 1, and the output shaft of the stirring motor passes through the top of the tank body 1 and is connected to the stirring shaft to drive the stirring shaft to rotate. An exhaust port is provided on one side of the tank body 1, which is connected to the exhaust gas treatment equipment via a pipe. The stirring blades stir the material in the tank body 1, thereby ensuring uniform mixing. The other structures of the tank body 1 itself are prior art and will not be described in detail here.

[0036] In some embodiments, as Figures 1 to 7As shown, the lifting mechanism 6 includes a column 61 and a wire-taking drum 62; one end of the column 61 is fixed to the top of the tank body 1; the other end of the column 61 extends upward, and a roller 63 is rotatably provided at the top of the column 61; the wire-taking drum 62 is rotatably set on the top of the tank body 1; a connecting wire 64 is wound around the wire-taking drum 62, one end of the connecting wire 64 is fixed to the wire-taking drum 62, and the other end is connected to the overhanging side of the material receiving bag 5 after passing through the roller 63; wherein, when loading, the wire-taking drum 62 can reel up the connecting wire 64, and the overhanging side of the material receiving bag 5 can be located above the discharge port 21 under the tension of the connecting wire 64, so that the material in the material receiving bag 5 falls into the hopper 2.

[0037] It should be noted that a support base 11 is fixedly provided on the top of the tank body 1, and the wire take-up drum 62 is rotatably set on the support base 11; a servo motor is connected to the support base 11, and the output shaft of the servo motor is connected to the wire take-up drum 62; the output shaft of the servo motor can drive the wire take-up drum 62 to rotate, thereby facilitating the connecting line 64 to pull the overhanging side of the material receiving bag 5; after all the materials in the material receiving bag 5 are poured into the hopper 2, the wire take-up drum 62 rotates in the opposite direction, and the overhanging side of the material receiving bag 5 can move downward under the action of gravity.

[0038] Exemplarily, both ends of the roller 63 are fixed with a limit plate 631, and the diameter of the limit plate 631 is larger than the diameter of the roller 63, so that the connecting line 64 is located between the two limit plates 631; a horizontal plate 632 is connected to the column 61, and the horizontal plate 632 is located at the top position of the roller 63. The horizontal plate 632 is used to limit the height direction of the connecting line 64 to reduce the situation where the connecting line 64 is separated from the roller 63.

[0039] In some embodiments, as Figures 1 to 7 As shown, the lifting mechanism 6 includes a first electric push rod (not shown in the figure), which is vertically arranged, the shell of the first electric push rod is connected to the top of the tank body 1, and the pushing end of the first electric push rod is connected to the overhanging side of the receiving bag 5.

[0040] It should be noted that by extending the pushing end of the first electric push rod upward, the overhanging side of the material receiving bag 5 can be driven to move upward, and then during the loading process, the material in the material receiving bag 5 is poured into the hopper 2, reducing material waste and also reducing the material accumulation in the material receiving bag 5.

[0041] In some embodiments, as Figures 1 to 7As shown, the outer wall of the hopper 2 has a sleeve 22 at the discharge port 21, and the material receiving bag 5 is mounted on the sleeve 22. The connection between the material receiving bag 5 and the sleeve 22 has a fixing structure. The fixing structure includes an elastic strip 7, one end of which has a through hole for a bolt to pass through, and the other end has a threaded hole. When the material receiving bag 5 is mounted on the sleeve 22, the elastic strip 7 is located at the connection position of the material receiving bag 5. The engagement of the bolt and the threaded hole enables the annular groove to clamp the material receiving bag 5.

[0042] It should be noted that after the elastic strip 7 is sleeved on the sleeve position of the material receiving bag 5 , by tightening the bolts, the elastic strip 7 can clamp the sleeve position of the material receiving bag 5 , thereby fixing the material receiving bag 5 on the sleeve 22 .

[0043] In some embodiments, as Figures 1 to 7 As shown, an annular groove 23 is provided on the outer peripheral wall of the sleeve 22 , and the elastic strip 7 is plugged into and fitted in the annular groove 23 .

[0044] It should be noted that, by providing an annular groove 23 on the outer peripheral wall of the sleeve 22 and positioning the elastic strip 7 in the annular groove 23 , the elastic strip 7 can be limited, thereby reducing the possibility of the elastic strip 7 slipping out of the sleeve 22 .

[0045] In some embodiments, as Figures 1 to 7 As shown, the outer wall of the sleeve 22 has several threaded holes, each of which can be equipped with a bolt. The material receiving bag 5 has through holes aligned with the threaded holes. When the material receiving bag 5 is mounted on the sleeve 22, the bolts are separated from the sleeve 22. After the material receiving bag 5 is mounted, the bolts are threadedly engaged with the sleeve 22 to tighten the material receiving bag 5. The material receiving bag 5 is fixed with a collar at the position of each through hole.

[0046] It should be noted that the bolts on the outer wall of the sleeve 22 are evenly arranged along the circumference of the sleeve 22. After the material receiving bag 5 is inserted into the sleeve 22, the ring on the material receiving bag 5 can be aligned with the threaded hole on the sleeve 22. At this time, the threaded end of the bolt passes through the ring and cooperates with the thread of the sleeve 22, so that the material receiving bag 5 can be fixed on the sleeve 22.

[0047] In some embodiments, as Figures 1 to 7 As shown, the driving component 4 includes a second electric push rod, which is arranged on the top of the tank body 1, and the pushing top end of the second electric push rod is connected to the sealing plate 3.

[0048] It should be noted that the second electric push rod is fixed to the top of the tank body 1. The second electric push rod provides a pushing force to the sealing plate 3, which can drive the sealing plate 3 to move, thereby making the sealing plate 3 close the hopper 2, or making the sealing plate 3 open the hopper 2.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
