Description

Technical Field

[0001] This invention relates to the field of emulsified asphalt processing technology, specifically to a mixing and blending equipment for emulsified asphalt production. Background Technology

[0002] Asphalt is a dark brown, semi-solid or liquid organic material that typically appears as a byproduct of natural fuels. While it possesses excellent properties such as high viscosity and insolubility in water, it cannot be directly used in road construction. With the continuous development of science and technology, emulsified asphalt has emerged in the market. In transportation infrastructure construction, emulsified asphalt has gradually demonstrated its energy-saving, environmentally friendly, and convenient construction characteristics, making it an indispensable material in road construction. Therefore, mixing and blending equipment for producing emulsified asphalt has been developed.

[0003] Currently available emulsified asphalt mixing equipment can mix asphalt and emulsifier for production. However, during the production process, defects in the feeding channel often prevent the asphalt raw material and emulsion from fully contacting each other during the feeding stage. As a result, some parts of the asphalt and emulsion may not mix properly during the contact process, making the emulsified asphalt produced later unusable. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a mixing and blending equipment for producing emulsified asphalt, comprising a device shell and an inner cylinder. A mixing device is fixedly installed on the top of the device shell, penetrating the device shell and extending into its inner cavity. A motor is fixedly installed at the center of the bottom of the device shell via a bracket. A mixing and shearing device is fixedly installed at the output end of the motor, penetrating the device shell and extending into its inner cavity. A discharge device is fixedly installed at the bottom of the device shell. Air barriers are detachably installed on the outer surfaces of both the mixing device and the discharge device, penetrating both the mixing device and the discharge device and extending into their respective interiors. Support feet are fixedly installed at the four corners of the bottom of the device shell. By setting up the mixing device, the asphalt and emulsion are ensured to fully contact each other before flowing into the device from the output end of the mixing device for the next process, thus preventing localized unmixing between the asphalt and the emulsion.

[0005] Preferably, the inner cylinder is fixedly installed at the bottom of the inner cavity of the device shell, and the top of the inner cylinder is fixedly connected to the top of the inner cavity of the device shell. A temperature-controlled jacket is formed between the device shell and the inner cylinder. Radiant tubes are fixedly installed on both sides of the inner wall of the temperature-controlled jacket. The two ends of the radiant tubes penetrate the device shell and extend to its outer side. A discharge auxiliary device is fixedly installed at the bottom of the inner cavity of the device shell. The discharge device penetrates the device shell and the discharge auxiliary device and extends into the inner cavity of the device shell. By setting up the temperature-controlled jacket, the operator can preheat the liquid in the temperature-controlled jacket through the radiant tubes before the device starts working, thus achieving the purpose of controlling the internal temperature of the device as needed.

[0006] Preferably, the mixing device includes a first inlet and a second inlet, the first inlet and the second inlet are fixedly installed on the top of the device housing, and the first inlet and the second inlet penetrate the device housing and extend into its inner cavity.

[0007] Preferably, a mixer is fixedly installed between the first and second inlets. A spiral feed pipe is fixedly installed at the bottom of the mixer. Air barriers are detachably installed on the outer surfaces of the first and second inlets, respectively. The air barriers pass through the first and second inlets and extend into their interiors, and are located on the outside of the device housing. By providing a mixer, when asphalt and emulsion are poured into the first and second inlets respectively, they first enter the mixer for contact mixing before entering the device interior through the spiral feed pipe for the next process, thus increasing the contact time between the asphalt and emulsion.

[0008] Preferably, the air barrier includes a gas baffle, a handle is fixedly mounted on the outer surface of the gas baffle, and a grip groove is formed at the top of the handle, extending through the handle to the other side. By setting up the air barrier, after the operator has finished filling the asphalt and emulsion through the first and second inlets, the gas baffle is installed back inside the first and second inlets, preventing external air from entering the device, thus preventing oxygen in the air from reacting with the emulsified asphalt in an oxidation reaction.

[0009] Preferably, the stirring and shearing device includes a rotating rod, the bottom of which is fixedly connected to the output end of the motor. The rotating rod passes through the outer shell of the device and the discharge auxiliary device and extends into the cavity inside the outer shell of the device. A rotating cylinder is fixedly installed on the outer surface of the outer shell of the device.

[0010] Preferably, a distributor and a mixing cutter are fixedly installed on the outer surface of the rotating drum. Both the distributor and the mixing cutter are located inside the cavity of the device housing, with the distributor positioned above the mixing cutter. When the mixture of asphalt and emulsifier falls into the device via a motor, centrifugal force causes larger asphalt particles to enter the cutting area of ​​the mixing cutter for cutting, thus achieving the goal of controlling the size of the asphalt particles.

[0011] Preferably, the distributor includes a distribution plate, which is fixedly installed on the outer surface of the rotating drum. A straight discharge chute and a spiral discharge chute are respectively formed on the top of the distribution plate, and the straight discharge chute and the spiral discharge chute are interconnected. By setting up the distributor, when the asphalt and emulsifier mixture falls from the spiral feed pipe to the top of the distributor, the rotation of the distributor causes the asphalt and emulsifier mixture to enter the straight discharge chute and the spiral discharge chute. Part of the mixture will directly fall through the straight discharge chute to the cutting section of the mixing cutter for preferential centrifugal cutting, while another part of the mixture will enter the next connected straight discharge chute through the spiral discharge chute and fall from that straight discharge chute into the cutting section of the mixing cutter. Therefore, the asphalt and emulsifier mixture can be evenly distributed into all areas of the mixing cutter.

[0012] Preferably, the mixing cutter includes a mixing blade, which is fixedly installed on the outer surface of the rotating drum. The mixing blade is located below the distribution plate. A small-diameter sieve hole is provided on one side of the mixing blade, penetrating the mixing blade and extending to the other side. An asphalt cutter is fixedly installed at the outer edge of the mixing blade, and a discharge aid is fixedly installed at the bottom of the outer edge of the mixing blade. By setting the small-diameter sieve hole, when asphalt particles are cut to a size suitable for the small-diameter sieve hole, this diameter of asphalt can directly pass through the small-diameter sieve hole when the mixing blade rotates, reducing the resistance when the mixing blade rotates, thus saving energy consumed by the mixing and cutting part.

[0013] This invention provides a mixing and blending device for producing emulsified asphalt. It has the following beneficial effects: (i) The mixing equipment for producing emulsified asphalt, by setting up a mixing device, ensures that the asphalt and emulsion come into full contact before flowing into the equipment from the output end of the mixing device for the next process, thus achieving the purpose of preventing local unmixing between the asphalt and the emulsion.

[0014] (ii) The mixing equipment for producing emulsified asphalt is equipped with a temperature-controlled jacket. Before the equipment starts working, the staff can preheat the liquid in the temperature-controlled jacket through the radiant tube, thus achieving the purpose of controlling the internal temperature of the equipment according to the needs.

[0015] (III) The mixing equipment for producing emulsified asphalt is equipped with a mixer. When asphalt and emulsion are poured into the first inlet and the second inlet respectively, they will first enter the mixer for contact mixing, and then enter the device through the spiral feed pipe for the next process. Therefore, the contact time between asphalt and emulsion is increased.

[0016] (iv) The mixing equipment for producing emulsified asphalt is equipped with an air barrier. After the workers have finished filling the asphalt and emulsion through the first and second inlets, the gas barrier is installed back inside the first and second inlets to prevent external air from entering the device. Therefore, it can prevent oxygen in the air from reacting with the emulsified asphalt.

[0017] (v) The mixing equipment for producing emulsified asphalt is equipped with a distributor. When the mixture of asphalt and emulsifier falls from the spiral feed pipe to the top of the distributor, the mixture will enter the straight feed chute and the spiral feed chute through the rotation of the distributor. Part of the mixture will fall directly through the straight feed chute to the cutting part of the mixing cutter for centrifugal cutting. The other part of the mixture will enter the next straight feed chute connected to it through the spiral feed chute and fall from the straight feed chute into the cutting part of the mixing cutter. Therefore, the mixture of asphalt and emulsifier can be evenly distributed into each area of ​​the mixing cutter.

[0018] (vi) The mixing equipment for producing emulsified asphalt is equipped with small-diameter screen holes. When the asphalt particles are cut to a size that matches the small-diameter screen holes, the asphalt of that diameter can pass directly through the small-diameter screen holes when the mixing blades rotate, which reduces the resistance when the mixing blades rotate and thus saves the energy consumed by the mixing and cutting part.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-6 This invention provides a technical solution comprising a device housing 1 and an inner cylinder 7. A mixing device 2 is fixedly installed on the top of the device housing 1, extending through the housing and into its inner cavity. A motor 3 is fixedly installed at the center of the bottom of the housing 1 via a bracket. A stirring and shearing device 8 is fixedly installed at the output end of the motor 3, extending through the housing and into its inner cavity. A discharge device 4 is fixedly installed at the bottom of the housing 1. Air barriers 11 are detachably installed on the outer surfaces of both the mixing device 2 and the discharge device 4, extending through both and into their respective interiors. Support feet 5 are fixedly installed at the four corners of the bottom of the housing 1. By setting up the mixing device 2, the asphalt and emulsion are ensured to fully contact each other before flowing into the device from the output end of the mixing device 2 for the next process, thus preventing localized unmixing between the asphalt and emulsion.

[0023] The inner cylinder 7 is fixedly installed at the bottom of the internal cavity of the outer shell 1. The top of the inner cylinder 7 is fixedly connected to the top of the internal cavity of the outer shell 1. A temperature-controlled jacket 9 is formed between the outer shell 1 and the inner cylinder 7. The temperature-controlled jacket 9 is filled with a heating medium. Radiation tubes 6 are fixedly installed on both sides of the inner wall of the temperature-controlled jacket 9. The radiation tubes 6 are spiral-shaped, and both ends of the radiation tubes 6 penetrate the outer shell 1 and extend to its outer side. A discharge aid 10 is fixedly installed at the bottom of the internal cavity of the outer shell 1. The discharge aid 10 is conical to facilitate discharge. The discharge device 4 penetrates the outer shell 1 and the discharge aid 10 and extends into the internal cavity of the outer shell 1. By setting up the temperature-controlled jacket 9, the operator can preheat the liquid in the temperature-controlled jacket 9 through the radiation tubes 6 before the device starts working, thus achieving the purpose of controlling the internal temperature of the device as needed.

[0024] The mixing device 2 includes a first inlet 22 and a second inlet 23. The first inlet 22 and the second inlet 23 are fixedly installed on the top of the device housing 1. The first inlet 22 and the second inlet 23 penetrate the device housing 1 and extend into its inner cavity.

[0025] A mixer 21 is fixedly installed between the first inlet 22 and the second inlet 23. The mixer 21 increases the contact time between the asphalt and the emulsifier. A spiral feed pipe 24 is fixedly installed at the bottom of the mixer 21. This spiral feed pipe 24 reduces the flow rate of the asphalt-emulsifier mixture into the next stage, allowing for more thorough contact. Air barriers 11 are detachably installed on the outer surfaces of the first inlet 22 and the second inlet 23, respectively. The air barriers 11 penetrate the first inlet 22 and the second inlet 23 and extend into their interiors. The air barriers 11 are located on the outside of the device housing 1. By installing the mixer 21, when the asphalt and emulsifier are poured into the first inlet 22 and the second inlet 23, they first enter the mixer 21 for contact mixing before entering the device interior through the spiral feed pipe 24 for the next process, thus increasing the contact time between the asphalt and the emulsifier.

[0026] Please see Figure 7The present invention provides a technical solution: the air barrier 11 includes a gas baffle 111, and a handle 112 is fixedly installed on the outer surface of the gas baffle 111. A grip groove 113 is provided at the top of the handle 112, allowing the operator to insert and remove the air barrier 11 more securely. The grip groove 113 passes through the handle 112 and extends to the other side. By setting the air barrier 11, after the operator has finished filling the asphalt and emulsion through the first inlet 22 and the second inlet 23, the gas baffle 111 is installed back inside the first inlet 22 and the second inlet 23, preventing external air from entering the device. Therefore, it can prevent oxygen in the air from reacting with the emulsified asphalt.

[0027] Please see Figure 8-11 The present invention provides a technical solution: the stirring and shearing device 8 includes a rotating rod 81, the bottom of the rotating rod 81 is fixedly connected to the output end of the motor 3, the rotating rod 81 passes through the device housing 1 and the discharge auxiliary device 10 and extends to the cavity inside the device housing 1, and a rotating cylinder 82 is fixedly installed on the outer surface of the device housing 1.

[0028] The outer surface of the rotating drum 82 is fixedly equipped with a distributor 83 and a mixing cutter 84, both of which are located inside the cavity of the device housing 1, with the distributor 83 positioned above the mixing cutter 84. When the motor 3 operates, and the mixture of asphalt and emulsifier falls into the device, centrifugal force causes larger asphalt particles to enter the cutting area of ​​the mixing cutter 84 for cutting, thus achieving the purpose of controlling the size of the asphalt particles.

[0029] The distributor 83 includes a distribution disc 831, which is conical to prevent asphalt from accumulating on it. The distribution disc 831 is fixedly installed on the outer surface of the rotating drum 82. The top of the distribution disc 831 is provided with a straight discharge groove 832 and a spiral discharge groove 833, which are interconnected. By setting up the distributor 83, when the asphalt and emulsifier mixture falls from the spiral feed pipe 24 to the top of the distributor 83, the asphalt and emulsifier mixture will enter the straight feed trough 832 and the spiral feed trough 833 through the rotation of the distributor 83. Part of the mixture will fall directly through the straight feed trough 832 to the cutting part of the mixing cutter 84 for preferential centrifugal cutting, while the other part of the mixture will enter the next straight feed trough 832 connected to it through the spiral feed trough 833, and fall from the straight feed trough 832 into the cutting part of the mixing cutter 84. Therefore, the asphalt and emulsifier mixture can be evenly distributed into each area of ​​the mixing cutter 84.

[0030] The mixing cutter 84 includes a mixing blade 841, which is fixedly installed on the outer surface of the rotating drum 82. The mixing blade 841 is located below the distribution plate 831. A small-diameter sieve hole 842 is opened on one side of the mixing blade 841. The small-diameter sieve hole 842 penetrates the mixing blade 841 and extends to the other side. An asphalt cutter 843 is fixedly installed on the outer edge of the mixing blade 841. The asphalt cutter 843 is evenly distributed on the outer edge of the mixing blade 841 and is used to cut larger asphalt particles. A discharge aid 844 is fixedly installed at the bottom of the outer edge of the mixing blade 841. One side of the discharge aid 844 is arc-shaped and the other side is square. When the motor 3 rotates clockwise, the arc-shaped side of the discharge aid 844 will not block the emulsified asphalt from passing through. When the motor 3 rotates counterclockwise, the square side will push the emulsified asphalt into the discharge device 4. By setting a small-diameter sieve hole 842, when asphalt particles are cut to a size that matches the small-diameter sieve hole 842, asphalt of that diameter can directly pass through the small-diameter sieve hole 842 when the mixing blade 841 rotates, reducing the resistance when the mixing blade 841 rotates, thus saving the energy consumed by the mixing and cutting part.

[0031] During operation, the operator first controls the radiant tube 6 to raise the internal temperature of the device to the temperature required for the asphalt emulsification reaction, and then turns on the power to the motor 3 to make the mixing and shearing device 8 rotate clockwise at a uniform speed. Then, the air barrier 11 is pulled out from the first feed port 22 and the second feed port 23, and the asphalt particles and emulsion are poured into the mixing device 2 through the first feed port 22 and the second feed port 23 respectively. After the feeding is completed, the air barrier 11 is inserted back into the first feed port 22 and the second feed port 23. The asphalt particles and emulsion fully contact each other in the mixer 21 to form an asphalt emulsion mixture. The asphalt emulsion mixture slowly flows into the cavity of the device shell 1 through the spiral feed pipe 24. When the asphalt emulsion mixture falls onto the surface of the distributor 83, part of the mixture will fall directly through the straight feed chute 832 to the cutting part of the mixing cutter 84 for preferential centrifugal cutting, while the other part of the mixture will enter the cutting part of the distributor 84 through the spiral feed chute 833. The next straight feed chute 832 is connected, and the material falls from the straight feed chute 832 into the cutting part of the mixing cutter 84. At this time, the mixing cutter 84 will mix and cut the asphalt emulsion mixture. After the reaction is completed, the radiation tube 6 stops working. When the internal temperature of the instrument drops to a suitable discharge temperature, the operator rotates the motor 3 counterclockwise and pulls the air barrier 11 out of the discharge device 4. The discharge aid 844 will push the emulsified asphalt from the top of the discharge aid 10 to the top of the discharge device 4. The operator collects and stores the emulsified asphalt. After collection, the air barrier 11 is pulled out from the first feed port 22 and the second feed port 23. Then, the first feed port 22 and the second feed port 23 are connected to the water source to clean the inside of the device. After cleaning, the power of the motor 3 is turned off, and the air barrier 11 is inserted into the first feed port 22, the second feed port 23 and the discharge device 4. The work is completed.

[0032] In the feeding and mixing section, when asphalt and emulsion are poured in from the first feed port 22 and the second feed port 23 respectively, they will first enter the mixer 21 for contact mixing, and then enter the device through the spiral feed pipe 24 for the next process.

[0033] In the mixing and cutting section, when the mixture of asphalt and emulsifier falls into the device, the larger asphalt particles enter the cutting area of ​​the mixing cutter 84 through centrifugal force. The asphalt cutter 843 will cut them. When the asphalt particles are cut to a size that fits the small diameter sieve hole 842, the asphalt of this diameter can pass directly through the small diameter sieve hole 842 when the mixing blade 841 rotates. The large diameter asphalt particles will continue to roll towards the mixing cutter 84 through centrifugal force.

[0034] In the part of the discharge timing control, after the reaction inside the equipment is completed, the emulsified asphalt under high temperature is easily oxidized. The staff can grasp the timing of discharge. When the temperature drops to a certain range, the air barrier 11 set in the discharge device 4 is pulled out to remove the emulsified asphalt inside the equipment, so as to prevent the emulsified asphalt from being oxidized and wasted due to incorrect discharge timing.
