[0055] Further, the cam shaft 27 is installed on the cylinder wall 55 of the oscillating stirring cylinder through a bearing and a bearing frame, and the cam 28 is installed on the cam shaft 27.

[0056] Working principle of the high-temperature stirring part 11: since the colored asphalt is a high-molecular material, the intermolecular block and polymerization force are large, and the fluidity is poor, it is difficult to achieve ideal effect by using ordinary stirring mode. The present application combines ordinary rotary stirring, piggyback type oscillating stirring and auxiliary stirring, so as to make up for the defects of ordinary rotary stirring and achieve the best stirring effect.

[0057] Problems existing in the ordinary stirring mode Figure 4 The rotary stirring device commonly used in the working process has a linear velocity gradient from the shaft center part to the top end of the stirring blade, which will cause the uniformity of the mixed material on different circular rings in the stirring drum to be different. The part close to the shaft center is a low-efficiency area of stirring, since the colored asphalt is a high-molecular material, the intermolecular block and polymerization force are large, and the fluidity is poor, so the part close to the shaft center is basically a stirring blind area.

[0058] In order to solve the above problems, the present application adds piggy oscillation stirring and auxiliary stirring, the piggy oscillation stirring makes the stirring blade oscillate at high speed through two eccentric blocks, so that the mixed material moves outward from the shaft center, and the mixed material is stirred through the collision of the blade and the impact of the oscillation wave, and at the same time, vortex motion is generated. The auxiliary stirring moves inward through the auxiliary stirring plate 24, cooperates with the vortex generated by the oscillation wave to form a vortex flow, accelerates the flow of colored asphalt, uses the mixed material flow in the low-efficiency stirring area and the high-efficiency stirring area, and achieves the best stirring effect.

[0059] The working principle of the piggy oscillation stirring: the hydraulic pump drives the upper half shaft 19 to rotate counterclockwise, drives the upper middle gear 30 to rotate counterclockwise, since the upper middle gear 30 is in gear with the right gear 22, the upper middle gear 30 drives the right gear 22 to rotate clockwise, and drives the right eccentric block 23 to rotate clockwise; the hydraulic pump drives the lower half shaft 36 to rotate clockwise, drives the lower middle gear 32 to rotate clockwise, since the lower middle gear 32 is in gear with the left gear 34, the lower middle gear 32 drives the right gear 22 to rotate counterclockwise, and drives the right eccentric block 23 to rotate counterclockwise; under the action of power, the left and right eccentric blocks rotate in opposite directions. As shown in Figure 4 Fig. 1, in Figure 4 (a) position, the two eccentric blocks are in the same direction, the eccentric force is superimposed to the right, so that the blade swings to the right; the right eccentric block 23 rotates clockwise by 90 degrees, the left eccentric block 33 rotates counterclockwise by 90 degrees, and reaches Figure 4 (b) position, the two eccentric blocks are in opposite directions, the eccentric force generates a torsion, so that the blade twists (twists); the right eccentric block 23 rotates clockwise by 90 degrees, the left eccentric block 33 rotates counterclockwise by 90 degrees, and reaches Figure 4 (c) position, the two eccentric blocks are in the same direction, the eccentric force is superimposed to the left, so that the blade swings to the left; the right eccentric block 23 rotates clockwise by 90 degrees, the left eccentric block 33 rotates counterclockwise by 90 degrees, and reaches Figure 4 (d) position, the two eccentric blocks are in opposite directions, the eccentric force generates a torsion, so that the blade twists (twists). This cycle makes the blade swing left and right and twist, generating vibration force and oscillation wave. The piggy oscillation stirring makes the stirring blade oscillate at high speed through two eccentric blocks, so that the mixed material moves outward from the shaft center, and the mixed material is stirred through the collision of the blade and the impact of the oscillation wave, and at the same time, vortex motion is generated.

[0060] The stirring blade of the piggy stirring of the low-temperature stirring system 58 is up and down swing, and the stirring blade of the piggy oscillation stirring is front and back or left and right swing.

[0061] The working principle of the auxiliary stirring device is as follows: the hydraulic pump drives the camshaft 27 to rotate, and the camshaft 27 drives the cam 28 to rotate. The large radius part of the cam 28 drives the pushing plate 29 to move inward against the elastic force of the pushing spring 26, and drives the auxiliary stirring plate 24 to move inward. The cam 28 continues to rotate, and the small radius part gradually reduces the outward movement of the pushing plate 29 against the elastic force of the pushing spring 26, and drives the auxiliary stirring plate 24 to move outward. The above process is repeated, and the auxiliary stirring plate 24 moves inward to form a vortex with the vortex generated by the oscillation wave, which accelerates the flow of the colored asphalt, and the mixture flows in the low-efficiency stirring area and the high-efficiency stirring area, thereby achieving the best stirring effect.

The inlet of the gear pump 39 is communicated with the oscillating stirring cylinder through the opening of the outer cover 37, and the outlet of the gear pump 39 is communicated with the sleeve 71 through the upper opening 70 of the sleeve 71.

[0064] The working principle of the granule processing unit is as follows: the hydraulic pump drives the gear pump 39 to work, and color asphalt is drawn from the oscillating stirring cylinder into the sleeve 71; the hydraulic pump drives the processing gear shaft 73 to rotate, and drives the processing gear 38 to rotate, the clockwise rotation of the processing gear 38 drives the rack 72 to move leftward, and drives the ejector column 40 to move leftward, so that the color asphalt is extruded from the sleeve 71 to the outer wall of the oscillating stirring cylinder; the counterclockwise rotation of the processing gear 38 drives the ejector column 40 to move rightward, and the gear pump 39 draws the color asphalt from the oscillating stirring cylinder into the sleeve 71 again; the clockwise rotation of the processing gear 38 is repeated, and the color asphalt is extruded from the sleeve 71 to the outer wall of the oscillating stirring cylinder and cooled by the cooling system to form a color asphalt rod. The hydraulic pump drives the cutting gear 45 to rotate, the rotation of the cutting gear 45 drives the cutting gear shaft 69 to slide along the cutting gear shaft sleeve 68, and the cutting gear shaft 69 drives the cutting blade 43 to cut the color asphalt rod into segments and process the color asphalt rod into color asphalt granules 75. The next time the color asphalt rod is formed, the hydraulic pump drives the cutting gear 45 to rotate in the reverse direction, and the cutting blade 43 cuts the color asphalt rod in the reverse direction.

Since a large amount of heat is required for the production of epoxy resin and the mixing of color asphalt, the heat cannot be completely utilized, and the waste heat can be used for refrigeration or utilized in various production links. The heat recovery system stores the waste heat in the color asphalt production into the heat preservation cavity, and transports the waste heat to the refrigeration system or other production links through the air pipe, so that the waste heat is utilized and the energy consumption is reduced.

[0066] In order to achieve better results, in one embodiment, the pig-type vibrating mixing color asphalt production machine further comprises a cooling unit, which comprises a cooling cavity 67 arranged on the side of the oscillating stirring cylinder, a heat energy refrigerator 46 arranged on the cooling cavity 67, and a granule outlet 42 arranged at the bottom of the cooling cavity 67. The cooling unit is used for cooling the color asphalt extruded from the sleeve 71 to the outside of the oscillating stirring cylinder.

[0067] Further, the cooling system is composed of a cooling cavity 67, a cold air inlet, a heat energy refrigerator 46, a cold air pipe and a switch. The cooling cavity 67 is located outside the oscillating stirring cylinder. The cooling system is used for cooling the color asphalt extruded from the sleeve 71 to the outer wall of the oscillating stirring cylinder to room temperature, so as to facilitate cutting and storage.

[0068] The working principle of the cooling system is as follows: the waste heat in the color asphalt production is used to generate cold air through the heat energy refrigerator 46, the cold air enters the cooling cavity 67 through the cold air pipe and the cold air inlet, and the color asphalt extruded from the sleeve 71 to the outer wall of the oscillating stirring cylinder is cooled to room temperature to form a color asphalt rod.

[0069] For better effect, in one embodiment, the pig-type vibration mixing color asphalt production machine further comprises a control system composed of control elements, control software, operating switches, etc.

[0070] The production speed of the epoxy resin, the adding proportion and speed of various raw materials, the stirring speed, the heating temperature, etc. can be controlled through the control system.

[0071] For better effect, in one embodiment, the pig-type vibration mixing color asphalt production processing technology uses the pig-type vibration mixing color asphalt production machine, which comprises the following steps:

[0072] Step 1, select the epoxy resin production equipment, take epoxy chloropropane and bisphenol A as the main raw materials, add catalyst and solvent in the production process, and process into liquid epoxy resin by using the general epoxy resin production process. Without adding curing agent, filler and stabilizer, the liquid epoxy resin is directly delivered to the low-temperature stirring cylinder of the pig-type vibration mixing color asphalt production machine.

[0073] Step 2, add tung oil, castor oil and extracted solvent oil into the low-temperature stirring cylinder of the pig-type vibration mixing color asphalt production machine, heat the mixture to 80℃ and stir for 15 minutes. The low-temperature stirring part 58 combines ordinary rotary stirring and pig-type stirring. The rotary stirring performs planar stirring, and the pig-type stirring realizes up-down stirring similar to the dolphin tail splashing water. Through the comprehensive action of horizontal force and vertical force, the mixture is impacted, rubbed, high-frequency vibrated and high-speed vortexed to realize three-dimensional stirring, so as to achieve ideal stirring effect. Then, the mixture is delivered to the modified asphalt special colloidal mill 6.

[0074] Step 3, add styrene-butadiene-styrene block copolymer, styrene-butadiene rubber and natural rubber into the modified asphalt special colloidal mill 6. Through the physical actions of shearing, rubbing, high-frequency vibration and high-speed vortex of the modified asphalt colloidal mill, the mixture is effectively emulsified, dispersed, homogenized and pulverized to modify the color asphalt. Then, the mixture is delivered to the oscillating stirring cylinder of the high-temperature stirring part 11.

[0075] Step 4, heat the mixture in the oscillating stirring cylinder to 185℃ and stir for 20 minutes, and then keep warm for 4 hours. Then, reduce the temperature of the mixture to 160℃, add fluorinated butyl rubber, vulcanized nickel, aluminum titanate and lithium aluminum silicon, and stir for 15 minutes. The oscillating stirring of the high-temperature stirring part 11 makes the stirring blades oscillate at high speed through two eccentric blocks, so that the mixture moves outward from the shaft center. The mixture is mixed by the collision of the blades and the impact of the oscillation wave, and vortex motion is generated at the same time. The auxiliary stirring moves inward through the auxiliary stirring plate 24, and forms vortex flow in cooperation with the vortex generated by the oscillation wave. The flow of the mixture in the low-efficiency stirring area and the high-efficiency stirring area is accelerated, so as to achieve the best stirring effect.

[0076] Step 5, reduce the temperature of the mixture to 140℃ in the oscillating stirring cylinder, add iron oxide red or titanium chromium green, cobalt blue, light chromium yellow and other pigments, stir for 20 minutes;

[0077] Step 6, reduce the temperature of the mixture to 120℃ in the oscillating stirring cylinder, add asphalt warm mix agent, stir for 20 minutes, to obtain directly usable colored asphalt;

[0078] Step 7, if not directly used, when the temperature of the colored asphalt is reduced to below 50℃, process into a granular shape, bag and store.

[0079] The traditional colored asphalt production adopts batch addition of finished epoxy resin and modifiers and additives in a reaction kettle, and the processing time needs more than 7 hours, and the production efficiency is low and the quality is unstable. According to different modifiers and additives, different equipment is designed, multi-stage mixing flow operation is adopted, the product quality is improved, the production efficiency is improved, and the production cost is reduced.

[0080] The low-temperature stirring part 58 combines ordinary rotary stirring and pig-type stirring. The rotary stirring performs planar stirring, and the pig-type stirring is similar to the water hitting of the dolphin tail to realize up-down stirring. Through the comprehensive action of horizontal force and vertical force, the mixture is impacted, rubbed, high-frequency vibrated and high-speed vortexed to realize three-dimensional stirring, so that the ideal stirring effect is achieved.

[0081] The high-temperature stirring part 11 increases oscillating stirring and auxiliary stirring on the basis of the traditional static rotary stirring. The oscillating stirring makes the stirring blades oscillate at high speed through two eccentric blocks, so that the mixture moves outward from the shaft center, and the mixture is mixed through the collision of the blades and the impact of the oscillation wave, and vortex motion is generated at the same time. The auxiliary stirring moves inward through the auxiliary stirring plate 24, cooperates with the vortex generated by the oscillation wave to form an eddy current, accelerates the flow of the colored asphalt, and uses the mixture flow of the low-efficiency stirring area and the high-efficiency stirring area to achieve the best stirring effect.

[0082] The pig-type vibration mixing color asphalt production machine has the advantages that the low-temperature stirring part 58 is stirred by the rotation of the low-temperature stirring blades 54 to realize planar stirring, the pig-type stirring device 57 realizes up and down stirring similar to the water splashing of a dolphin tail, and through the comprehensive action of horizontal force and vertical force, the mixture is impacted, rubbed, high-frequency vibrated and high-speed swirled to realize three-dimensional stirring and achieve ideal stirring effect; the pig-type oscillation stirring device and the auxiliary stirring device are arranged in the high-temperature stirring part 11, the oscillation stirring blades 66 realize high-speed oscillation through the two eccentric blocks, the mixture moves outward from the shaft center, the mixture is stirred through the impact of the oscillation wave and the swirled motion, the auxiliary stirring device moves inward through the auxiliary stirring plate 24 to form vortex flow in cooperation with the swirled motion generated by the oscillation wave, the mixture flow in the low-efficiency stirring area and the high-efficiency stirring area is used to achieve the best stirring effect; the particle processing part 56 extrudes the color asphalt from the sleeve 71 to the outer wall of the oscillation stirring cylinder to form a color asphalt rod through the reciprocating movement of the top material column 40, the cutting gear 45 rotates to drive the cutting gear shaft 69 to slide along the cutting gear shaft sliding sleeve 68, the cutting gear shaft 69 drives the cutting blade 43 to cut the color asphalt rod into segments to process into color asphalt particles 75; the pig-type vibration mixing color asphalt production machine has reasonable structure, realizes efficient and stable automatic production of color asphalt, is energy-saving and environment-friendly, reduces the use of manual work and reduces production cost.
