Description

Technical Field

[0001] The invention belongs to the field of asphalt preparation devices, and in particular relates to an asphalt recycled material lifting system. 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 often exists in the form of liquid or semi-solid petroleum. The surface is black and it is soluble in carbon disulfide and carbon tetrachloride. Asphalt is an organic gelling material that is waterproof, moisture-proof and anti-corrosive. Asphalt can be mainly divided into three types: coal tar asphalt, petroleum asphalt and natural asphalt: among them, coal tar asphalt is a by-product of coking. Petroleum asphalt is the residue after crude oil distillation. Natural asphalt is stored underground, and some form mineral layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in industries such as coatings, plastics, rubber, and paving roads.

[0003] The regeneration of asphalt is the reverse process of aging.

[0026] Example 1

[0027] like Figure 1-6 As shown, an asphalt recycled material lifting system includes a transmission frame 1, a driven shaft cylinder 101 and a driving shaft cylinder 102 respectively connected to both ends of the transmission frame 1, a driving mechanism 105 connected to the transmission frame 1 near the driving shaft cylinder 102, a plurality of inclined shaft cylinders 103 connected to the transmission frame 1, and a conveyor belt 104 wound around the driving shaft cylinder 102, the driven shaft cylinder 101 and the inclined shaft cylinder 103. The lower end of the transmission frame 1 is connected to a first lifting mechanism near the driven shaft cylinder 101, and the lower end of the transmission frame 1 near the middle and the driving shaft cylinder 102 are connected to a second lifting mechanism. A support frame 2 is arranged above, a storage hopper 201 is connected to the upper end of the support frame 2, and a recovery plate 202 parallel to the conveyor belt 104 is connected to the support frame 2, and a recovery mechanism 203 is connected to the recovery plate 202, and an output end of the recovery mechanism 203 is connected to a reflux pipe 204 communicated with the storage hopper 201. An adjusting mechanism 3 is arranged on the transmission frame 1, and the adjusting mechanism 3 is used to control the transmission amount of the material on the conveyor belt 104. The recovery mechanism 203 is used to recover the material that slides off the conveyor belt 104 and transmits it to the storage hopper 201.

[0028] The adjusting mechanism 3 includes a first bracket 301 and a second bracket 302 symmetrically connected to the transmission frame 1, a first movable chamber 3010 arranged in the first bracket 301, a first slide groove 3013 arranged on a side wall of the first movable chamber 3010, a first motor 3011 connected to the upper end of the first bracket 301, a first screw rod 3012 connected to the output shaft of the first motor 3011, a first inner slide plate 3015 arranged in the first movable chamber 3010, a second movable chamber 3020 arranged in the second bracket 302, and a first inner slide plate 3015 arranged in the second movable chamber 3020. A second slide groove 3021 on a side wall of the chamber 3020, a limiting rod 3022 arranged in the second movable chamber 3020, a second inner slide 3023 connected to the limiting rod 3022, and a cross baffle 303 connected between the first inner slide 3015 and the second inner slide 3023, the first inner slide 3015 is provided with a screw hole matching the first screw rod 3012, a ball 3014 is provided between the lower end of the first screw rod 3012 and the bottom of the first movable chamber 3010, and the cross baffle 303 is used to adjust the amount of material transmitted on the conveyor belt 104.

[0029] The lower end of the transverse baffle 303 is provided with a plurality of symmetrically arranged first receiving grooves 3030, and the middle position of the lower end of the transverse baffle 303 is provided with a second receiving groove 3032, an angle sensor 3036 is provided on one side wall of the first receiving groove 3030, a second motor 3035 is connected to the rear end wall of the transverse baffle 303, the output shaft of the second motor 3035 extends to the first receiving groove 3030 and is connected to the inclined scraper 3031, and the angle sensor 3036 is connected to the inclined scraper 3031. The angle sensor 3036 can accurately know the rotation angle of the inclined scraper 3031, and can achieve the control of the range of the inclined scraper 3031 in the material conveying space of the conveyor belt 104 to scrape the material, so as to achieve the effect of controlling the material conveying amount.

[0030] The upper end of the transverse baffle 303 is connected to an electric push rod 3034, the output end of the electric push rod 3034 extends to the second receiving groove 3032 and is connected to a horizontal scraper 3033, and the lower ends of the horizontal scraper 3033 and the inclined scraper 3031 are both connected to a cleaning layer.

[0031] The first lifting mechanism includes a first support column 1060, a first support screw 1061 arranged in the first support column 1060, and a first adjusting nut 1062 movably connected to the upper end of the first support column 1060, the first support screw 1061 is threadedly connected to the first adjusting nut 1062, and the first support screw 1061 extends to one end outside the first support column 1060 and is hinged to the transmission frame 1.

[0032] The second lifting mechanism includes a second support column 1070, a second support screw 1071 arranged in the second support column 1070, a second adjusting nut 1072 movably connected to the upper end of the second support column 1070, a connecting frame 1073 connected to the transmission frame 1, and an inclined support rod 1074 connected between the second support column 1070 and the transmission frame 1, a first inclined support screw 1075 and a second inclined support screw 1077 are arranged in the inclined support rod 1074, and the two ends of the inclined support rod 1074 are respectively movably connected with a third adjusting nut 1076 and a fourth adjusting nut 1078, one end of the first oblique support screw 1075 is hinged to the second support column 1070, and one end of the second oblique support screw 1077 is hinged to the transmission frame 1.

[0033] The adjustment principle of the first lifting mechanism and the second lifting mechanism is the same. When adjusting the first lifting mechanism, the length of the first support screw 1061 extending out of the first support column 1060 can be driven to increase or decrease by rotating the first adjusting nut 1062, thereby achieving the effect of adjusting one end of the transmission frame 1. Similarly, when the second lifting mechanism adjusts the support height, the second adjusting nut 1072 can be adjusted to control the extension length of the second support screw 1071. At the same time, in conjunction with the adjustment of the length of the oblique support rod 1074, the effect of conveniently controlling the support can be achieved, and the support is relatively stable.

[0034] One end of the recovery plate 202 is provided with an arc surface that cooperates with the driven shaft cylinder 101. The recovery mechanism 203 includes an outer shell, a spiral conveying pipe arranged in the outer shell, and a power motor connected to the outer shell. The power motor and the spiral conveying pipe are connected. The outer shell is provided with a feed port that cooperates with the recovery plate 202, and a discharge port is provided at the junction of the outer shell and the reflux pipe 204.

[0035] When the material in the storage hopper 201 falls onto the conveyor belt 104, it will gradually accumulate. The material is prone to relative movement on the conveyor belt 104. When the material slides and moves to the recovery plate 202, it enters the outer shell from the feed port on the outer shell. The power motor drives the spiral conveying pipe to gradually convey the material to the discharge port, and then re-conveys it to the storage hopper 201 from the reflux pipe 204, which can effectively reduce the loss of material.

[0036] When adjusting the amount of material conveyed by the conveyor belt 104, the first motor 3011 can be used to drive the first screw rod 3012 to rotate. When the first screw rod 3012 rotates, it drives the first inner slide plate 3015 to move in the first moving chamber 3010 and drives the cross baffle 303 to move in the same direction. The distance between the cross baffle 303 and the conveyor belt 104 can be adjusted. When a lot of material is accumulated on the conveyor belt 104, the cross baffle 303 can scrape the accumulated material to the subsequent conveyor belt 104, so that the output of the conveyor belt 104 is in a stable state, and the cross baffle 303 is also provided with an inclined scraper 30 31 and the horizontal scraper 3033, the inclined scraper 3031 can control the rotation angle so that it is in the conveying space of the conveyor belt 104. Similarly, the horizontal scraper 3033 can be pushed into the conveying space of the conveyor belt 104 by the electric push rod 3034, which can further control the conveying amount of the conveyor belt 104, and when the conveyor belt 104 is idle, the inclined scraper 3031 and the horizontal scraper 3033 are controlled to contact with the conveyor belt 104, and the surface of the conveyor belt 104 is cleaned by the cleaning layer on the inclined scraper 3031 and the horizontal scraper 3033, which can effectively extend the service life of the conveyor belt 104.

[0037] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
