Description

Technical Field

[0001] The invention relates to the technical field of stirring and mixing, and in particular to an environmentally friendly and energy-saving asphalt mixture stirring device. Background Art

[0002] Asphalt is a dark brown complex mixture of hydrocarbons of different molecular weights and their non-metallic derivatives, an organic substance with high viscosity. The material used in road construction is asphalt and other substances mixed together as the main base material for the road surface, and the asphalt must have a strict ratio with mineral powder and other ingredients.

[0003] Stirring asphalt raw materials by means of a stirring device is a commonly used mixing method in the prior art. For example, an environmentally friendly and energy-saving asphalt mixture stirring device disclosed in application number CN202110190730.2 provides a stirring device for stirring asphalt raw materials.

[0004] However, the above-mentioned stirring device puts the raw materials into the tank body, and then uses a motor to drive the stirring element to rotate for mixing. The stirring element is composed of a motor, multiple gears, multiple dragon components and other structures. The stirring intensity of each part of the stirring element is the same. However, after the material is put into the stirring tank, the size of the internal hydraulic pressure increases linearly from top to bottom, so the pressure on the stirring element increases linearly from top to bottom. Relatively speaking, the driving torque required for each part of the stirring element increases linearly from top to bottom, and the above-mentioned stirring device does not have this change, resulting in the raw materials at the bottom and the top of the stirring tank not being in an environment with the same stirring intensity. If the raw materials at the bottom want to obtain sufficient stirring intensity, the stirring intensity of the raw materials at the top will be excessive, requiring the determined torque of the driving device to be large enough, which puts forward higher requirements on the equipment, increases the equipment cost, and consumes a lot of stirring energy.

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The present invention will be further described below in conjunction with the embodiments.

[0035] Example: Refer to Figures 1 to 11 , an environmentally friendly and energy-saving asphalt mixture stirring device, comprising a tank body 1 and a tank cover 2 fixedly installed on the upper end of the tank body 1, so that the tank body 1 and the tank cover 2 can be easily installed;

[0036] A plurality of stirring components 6, the stirring components 6 include a motor 5, a mounting box 61, a mounting cavity 62, an iron core 63, a placement cavity 64, a rectangular groove 65, a magnetorheological fluid 66, a sliding rheostat 67, a DC power supply 68, a rotating shaft 69, a connecting paddle 610 and a stirring rod 611: the top of the rotating shaft 69 is rotatably mounted on the top inner wall of the tank body 1, the outer wall of the rotating shaft 69 is evenly rotatably mounted with a plurality of mounting boxes 61, the outer wall of the mounting box 61 is fixedly mounted with a plurality of stirring rods 611, and the interior of the mounting box 61 is provided with a mounting cavity 62, a placement cavity 64 and a rectangular groove The mounting chamber 62 and the rectangular chamber 65 are respectively located on both sides of the placement chamber 64. The placement chamber 64 is provided with a magnetorheological fluid 66. The rectangular chamber 65 is provided with a sliding rheostat 67. The sliding rheostat 67 includes a rheostat rod and a slide plate slidably arranged on the rheostat rod. The mounting chamber 62 is provided with a DC power supply 68 and an iron core 63. The mounting box 61 is provided with a coil and an intelligent switch. The sliding rheostat 67, the coil, the DC power supply 68 and the intelligent switch are electrically connected to form an adaptive circuit. The slide plate moves under the outer surface of the rheostat rod. The resistance of the sliding rheostat 67 in the adaptive circuit gradually decreases. The outer wall of the rotating shaft 69 is fixedly connected with multiple groups of connecting paddles 610, and the multiple groups of connecting paddles 610 are respectively located in the corresponding placement chambers 64. The top of the tank cover 2 is fixedly installed with a motor 5 for driving the rotating shaft 69, and a protective box is arranged outside the motor 5. The output end of the motor 5 drives the rotating shaft 69 to rotate, and then drives the stirring rod 611 to rotate in the magnetorheological fluid 66. Since the voltage of the DC power supply 68 is constant, the sliding piece moves down on the outer surface of the variable resistance rod, and the resistance of the connected circuit gradually decreases. Thereby, the current of the entire circuit is increased. Under the joint action of the iron core 63, the coil and the current, the electromagnetic field strength is increased, thereby affecting the state of the magnetorheological fluid 66. That is, the viscosity of the magnetorheological fluid 66 increases due to the increase in electromagnetic strength, thereby increasing the bonding strength between the stirring rod 611 and the magnetorheological fluid 66. With the cooperation of the rotating shaft 69, the stirring rod 611 and the magnetorheological fluid 66, corresponding stirring strength is provided for the raw materials at different positions in the tank body 1, thereby avoiding unnecessary load on the motor 5 and affecting the service life of the motor 5.

[0037] Adjustment component 7, the adjustment component 7 includes a pressure plate 71, a connecting rod 72, a movable plate 73 and a mounting groove 76: a mounting groove 76 is provided inside the mounting box 61, the mounting groove 76 is located on one side of the rectangular groove 65 and is connected to the rectangular groove 65, a movable plate 73 is slidably installed inside the mounting groove 76, the side wall of the movable plate 73 is fixedly connected to the sliding sheet, the top of the movable plate 73 is fixedly connected to the connecting rod 72, the connecting rod 72 is slidably connected to the mounting box 61, the top of the connecting rod 72 is fixedly connected to the pressure plate 71, and a reset component is provided at the bottom of the movable plate 73, the reset component includes a spring 75 installed in the mounting groove 76, the top of the spring 75 is fixedly connected to the bottom of the movable plate 73, and both sides of the spring 75 are provided with a limit plate 74, the limit plate 74 is installed in the mounting groove 76, and the movable plate 73 slides with the limit plate 74 The raw materials at different positions in the tank body 1 apply different hydraulic pressures to the tops of the multiple pressure plates 71, thereby pressing the connecting rod 72 downward. Since the side wall of the movable plate 73 is connected to the sliding portion of the sliding rheostat 67, the resistance of the connected circuit can be changed, thereby affecting the current, thereby affecting the strength of the electromagnetic field, changing the viscosity of the magnetorheological fluid 66 in the mounting box 61 at different positions in different tank bodies 1, thereby affecting the bonding strength between the stirring rod 611 and the magnetorheological fluid 66, thereby providing appropriate stirring strength for the raw materials at different positions in the tank body 1, and also reducing unnecessary loads on the motor 5. The setting of the spring 75 can improve the accuracy of the connected resistance, and ultimately provide a more accurate rotation speed for stirring the asphalt raw materials; it is also for resetting the movable plate 73 to facilitate later reuse.

[0038] Further, refer to Figures 8 to 11 , an auxiliary stirring assembly 9 is provided at the bottom of the stirring assembly 6, and the auxiliary stirring assembly 9 is connected to the rotating shaft 69 through a transmission assembly 8. The transmission assembly 8 includes a rectangular box 81, and the rectangular box 81 is rotatably connected to the rotating shaft 69. Two transmission wheels 82 are rotatably installed inside the rectangular box 81. The two transmission wheels 82 are connected through a transmission belt 83. One of the transmission wheels 82 is fixedly connected to the rotating shaft 69. The rotating shaft 69 rotates, driving one of the transmission wheels 82 to rotate, and the other transmission wheel 82 is driven to rotate with the cooperation of the transmission belt 83, thereby driving the auxiliary stirring assembly 9 to operate;

[0039] The auxiliary stirring assembly 9 includes an inner gear ring 96, and a plurality of mounting shells 91 are rotatably mounted on the outer wall of the inner gear ring 96. The outer wall of the mounting shell 91 is mounted on the inner wall of the tank body 1 through a limit assembly. An outward-turning stirring assembly is arranged between every two adjacent mounting shells 91. A fixing box 94 is fixedly mounted on the inner wall of one of the mounting shells 91. The fixing box 94 is mounted on the bottom of the rectangular box 81. A gear 95 is rotatably mounted inside the fixing box 94. The gear 95 is fixedly connected to the transmission wheel 82 through an axis. A through groove 93 is provided on the inner wall of the mounting shell 91. The gear 95 passes through the through groove 93 and meshes with the inner gear ring 96. Under the action of the transmission assembly 8, the gear 95 is driven to rotate. Because the gear 95 is meshed with the inner gear ring 96 for transmission, the inner gear ring 96 is driven to rotate in the plurality of mounting shells 91, so that the outward-turning stirring assembly radially stirs the raw material.

[0040] The outward-turning stirring assembly includes two rectangular plates 99, and the two rectangular plates 99 are respectively connected to the opposite sides of the two mounting shells 91. An annular cylinder 910 is rotatably installed between the two rectangular plates 99. The inner wall of the annular cylinder 910 is provided with a plurality of inclined grooves 911. The top of the mounting shell 91 is provided with a circular groove 92. The tops of the plurality of mounting shells 91 are fixedly connected with a plurality of arc-shaped protective shells 98, and the arc-shaped protective shells 98 are located at the tops of the corresponding circular grooves 92. A plurality of fixed columns 97 are arranged inside the circular grooves 92. The bottom of the fixed column 97 is fixedly connected to the top of the inner gear ring 96. The fixed column 97 is movably connected to the inclined groove 911. The outer wall of the annular cylinder 910 is fixedly connected with a plurality of connecting columns 912, the other end of the connecting column 912 is fixedly connected with a paddle 913, the inner gear ring 96 rotates, and multiple fixed columns 97 move inside the circular groove 92. When the circular groove 92 meets the inclined groove 911, under the cooperation of the circular groove 92 and the inclined groove 911, and because the distance between two adjacent fixed columns 97 is the length of an annular cylinder 910, the annular cylinder 910 is driven to rotate continuously, and then the connecting column 912 and the paddle 913 are driven to rotate, and the material is radially stirred to make it more fully stirred. The arc-shaped protective shell 98 has a certain protective effect on the fixed column 97 and the circular groove 92, preventing the material from flowing into the interior of the mounting shell 91 and affecting the use of the inner gear ring 96.

[0041] Further, refer to Figure 1 to Figure 2 The limiting assembly includes a telescopic rod 4, which is installed on the outer wall of the mounting shell 91. A plurality of annular plates 3 are installed on the outer wall of the tank body 1. A plurality of magnets are embedded in the inner wall of the annular plate 3. The telescopic rod 4 is ferromagnetic. The magnets are magnetically attracted to the corresponding telescopic rod 4, which facilitates the installation of the auxiliary stirring assembly 9 inside the tank body 1.

[0042] The working principle of this device is as follows:

[0043] When in use, the tank cover 2 is installed inside the tank body 1, and the multiple mounting shells 91 are supported by the telescopic rod 4 and the magnet in the annular plate 3, and then the raw material is injected into the tank body 1;

[0044] The intelligent switch in the circuit is turned on by an external remote control, so that the entire circuit is energized. When the raw materials are injected into the tank body 1, the raw materials at different positions in the tank body 1 apply different hydraulic pressures to the tops of the multiple pressure plates 71, thereby pressing the connecting rod 72 downward. Since the side wall of the movable plate 73 is connected to the sliding vane portion of the sliding rheostat 67, and since the voltage of the DC power supply 68 is constant, the sliding vane moves downward on the outer surface of the rheostat rod, and the resistance of the connected circuit gradually decreases, thereby increasing the current of the entire circuit. Under the joint action of the iron core 63, the coil and the current, the electromagnetic field strength increases, thereby affecting the state of the magnetorheological fluid 66, that is, the viscosity of the magnetorheological fluid 66 increases due to the increase in electromagnetic strength, thereby increasing the bonding strength between the stirring rod 611 and the magnetorheological fluid 66. Under the cooperation of the rotating shaft 69, the stirring rod 611 and the magnetorheological fluid 66, corresponding stirring strengths are provided for the raw materials at different positions in the tank body 1, thereby avoiding unnecessary load on the motor 5 and affecting the service life of the motor 5.

[0045] At the same time, under the belt transmission action of the transmission wheel 82 and the transmission belt 83, the gear 95 is driven to rotate, and because the gear 95 is meshed with the inner gear ring 96 for transmission, the inner gear ring 96 is driven to rotate in the multiple mounting shells 91. The inner gear ring 96 rotates, and the multiple fixed columns 97 move inside the circular groove 92. When the circular groove 92 encounters the inclined groove 911, under the cooperation of the circular groove 92 and the inclined groove 911, and because the distance between two adjacent fixed columns 97 is the length of an annular cylinder 910, the annular cylinder 910 is driven to rotate continuously, thereby driving the connecting The column 912 and the paddle 913 rotate radially to stir the material radially. Compared with the limitation of the prior art that only stirs the raw materials horizontally or vertically, the present invention adopts a stirring and mixing method that combines horizontal and vertical stirring. This method helps to break the agglomeration of the materials, and the stirring range is more comprehensive, thereby improving the mixing efficiency and uniformity, and mixing the asphalt raw materials more fully. The arc-shaped protective shell 98 has a certain protective effect on the fixed column 97 and the circular groove 92, preventing the material from flowing into the interior of the mounting shell 91 and affecting the use of the inner gear ring 96.

[0046] It should be noted that a temperature control device is provided inside the tank body 1 to provide a suitable temperature for stirring. This is a prior art and therefore is not elaborated in detail in this article.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
