Description

Technical Field:

[0001] The utility model relates to the technical field of asphalt processing equipment, and more specifically relates to an asphalt filling and stirring device. Background Art:

[0002] In the existing asphalt mixing plant, the asphalt for mixing is directly poured into the mixing tank together from the feed inlet. The feeding uniformity is poor, which affects the subsequent mixing effect. Moreover, the feeding amount cannot be controlled. It can only be weighed externally and then poured into the discharge tray, and the asphalt is recessed into the mixing tank through the discharge tray. During the whole process, part of the asphalt often leaks out from the discharge tray during pouring, affecting the accuracy of the feeding amount.

[0003] Moreover, a weighing step is required before feeding, which increases the previous process of feeding and the effect is not ideal. Summary of the Utility Model:

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an asphalt filling and stirring device. It can pour the asphalt into the asphalt filling tank first, and then transport it to the mixing tank through an asphalt delivery pump. It can achieve continuous transportation, and the asphalt filling tank can automatically weigh the incoming asphalt, eliminating the previous weighing process and improving the feeding efficiency and effect.

[0024] In an embodiment, as shown in Figures 1 to 5 a bitumen filling and mixing device includes a main box body 10. On the top surface of the bottom plate of the main box body 10, a bitumen filling tank 30 is placed. On the top surface of the bottom plate of the main box body 10 below the four corners of the bottom surface of the bitumen filling tank 30, first pressure sensors 31 are fixed. The sensing connection parts at the tops of the four first pressure sensors 31 are fixed at the four corners of the bottom surface of the bitumen filling tank 30;

[0025] On the top surface of the bottom plate of the main box body 10 on one side of the bitumen filling tank 30, a bitumen transfer pump 40 is fixed. The input pipe 41 of the bitumen transfer pump 40 extends into the bitumen filling tank 30, and the bottom end of the input pipe 41 is close to the top surface of the bottom plate of the bitumen filling tank 30;

[0026] The discharge end of the bitumen transfer pump 40 is connected to a discharge pipe 42. On the top surface of the bottom plate of the main box body 10 on one side of the bitumen transfer pump 40, a mixing tank 50 is fixed. The discharge end of the discharge pipe 42 is communicated with the mixing tank 50.

[0027] In this structure, the first pressure sensors 31 are all electrically connected to the control host through electric connection lines. In the control program of the control host, the maximum and minimum values of the feeding amount can be set. When in use, first extend the total discharge pipe of the external asphalt conveying device into the asphalt filling tank 30, and convey the asphalt into the asphalt filling tank 30 through the external asphalt conveying device (such as a conveying pump) (it is also possible to install an asphalt total input pump in the main box body 10, the feeding pipe of the asphalt total input pump extends out of the main box body 10 and is communicated with the external asphalt storage tank, and the discharge pipe of the asphalt total input pump extends into the asphalt filling tank 30. By operating the asphalt total input pump, the external asphalt can be conveyed into the asphalt filling tank 30). At this time, the four first pressure sensors 31 sense the weight and transmit the sensing signal to the control host. When the weight reaches the maximum value, the control host controls the external asphalt conveying device (if the asphalt total input pump is installed in the main box body 10, it controls the asphalt total input pump to stop operating) to stop conveying. Then, it controls the asphalt conveying pump 40 to operate, so as to convey the asphalt into the mixing tank 50. When the four first pressure sensors 31 sense that the weight reaches the minimum value, it means that feeding is required. At this time, the control host can control the external asphalt conveying device to operate (if the asphalt total input pump is installed in the main box body 10, it controls the asphalt total input pump to operate) to continue conveying. At the same time, it controls the asphalt conveying pump 40 to stop operating. When the weight sensed by the four first pressure sensors 31 reaches the maximum value, it controls the asphalt conveying pump 40 to operate, so as to realize continuous feeding. At the same time, the control program in the control host can accumulate the input asphalt weight, which is convenient for statistics. It can weigh the asphalt input into the asphalt filling tank 30 to ensure stable feeding. Moreover, in this process, basically no problem of asphalt leakage will occur, and the use effect is good. And when in use, a liquid level sensor can be installed on the inner side of the upper end of the asphalt filling tank 30. When the first pressure sensor 31 fails, the liquid level of the asphalt filling tank 30 can be sensed through the liquid level sensor. When it reaches the sensing limit set by the liquid level sensor, its sensing signal is transmitted to the control host, and the control host controls the external asphalt conveying device to stop operating to prevent overfeeding.

[0028] Furthermore, a total feeding port 51 is formed in the middle of the top plate of the mixing tank 50. The total feeding port 51 is communicated with the inner cavity of the mixing tank 50. A protective cover shell 52 is fixed on the top surface of the edge part of the top plate of the mixing tank 50. An upper cover plate 53 is fixed on the top surface of the protective cover shell 52. An upper horizontal feeding through groove 531 is formed in the middle of the upper cover plate 53. The upper horizontal feeding through groove 531 is communicated with the total feeding port 51. The upper cover plate 53 can prevent external materials from entering the mixing tank 50 and ensure the normal use of the mixing tank 50.

[0029] Furthermore, the discharging end of the discharging pipe 42 is connected to the middle part of one side wall of the material distributing pipe 43 or the feeding pipe end formed by connection. The material distributing pipe 43 is directly above the upper cover plate 53. A plurality of discharging pipes 431 are connected to the bottom plate of the material distributing pipe 43. The lower part of the discharging pipe 431 extends out of the bottom end of the corresponding through hole on the upper cover plate 53 and communicates with the total feeding port 51. The discharging pipes 431 make the asphalt feeding into the mixing tank 50 uniform, improving the uniformity of subsequent mixing.

[0030] Furthermore, a discharging through groove 54 extending left and right is formed in the middle of the bottom plate of the mixing tank 50, facing the lower discharging through groove on the bottom plate of the main box body 10.

[0031] Furthermore, the middle wall plate of the bottom plate of the mixing tank 50 extends left and right and bulges upward to form a middle arc-shaped wall plate part with an arc-shaped cross section. A discharging through groove 54 extending left and right is formed in the middle of the middle arc-shaped wall plate part.

[0032] Side support frames 55 are fixed to the bottom surfaces of the left and right ends of the middle arc-shaped wall plate part. Two circular end plates 56 are located between the two side support frames 55. The outer side wall of each circular end plate 56 is close to the corresponding side support frame 55. The left and right ends of the upper arc-shaped baffle plate 57 are fixed to the inner side walls of the upper parts of the two circular end plates 56. The top surface of the upper arc-shaped baffle plate 57 is closely attached to the bottom surface of the middle arc-shaped wall plate part and covers the discharging through groove 54;

[0033] A rotating shaft 561 is fixed to the middle of the circular end plate 56. The rotating shaft 561 is movably connected to the corresponding side support frame 55 through a bearing. A discharging push oil cylinder 58 is movably connected to the top surface of the bottom plate of the main box body on one side of the mixing tank 50. The end of the push rod of the discharging push oil cylinder 58 is movably connected to one end of a rotating arm 59 through a hinge shaft. The other end of the rotating arm 59 is fixed to the end of the corresponding rotating shaft 561 extending out of the side support frame 55.

[0034] Furthermore, the rotating arm 59 is an arc-shaped rotating arm.

[0035] A transverse strengthening rod is fixed between the lower parts of the two circular end plates 56. The two ends of the transverse strengthening rod are fixed to the inner side walls of the lower parts of the two circular end plates 56.

[0036] With this structure, when the materials in the mixing tank 50 are mixed, the upper arc-shaped baffle plate 57 can be pushed by the push rod of the discharging push oil cylinder 58 to turn over and no longer cover the discharging through groove 54, so that the mixed materials can come out from the discharging through groove 54 and finally come out from the lower discharging through groove on the bottom plate of the main box body 10. A material receiving tray or the like can be placed below for receiving materials, which is very convenient.

[0037] This discharging push oil cylinder 58 is connected to the corresponding solenoid valve of the hydraulic system through a connecting pipe and operates under the control of the hydraulic system, while the hydraulic system operates under the control of the control host. They are all conventional structures and will not be elaborated here.

[0038] In this embodiment, asphalt can be first poured into the asphalt filling tank 30 and then transported to the mixing tank 50 through the asphalt transfer pump 40. It can achieve continuous transportation, and the asphalt filling tank 30 can automatically weigh the incoming asphalt, eliminating the previous weighing process and improving the feeding efficiency and effect.
