Description

Technical Field

[0001] The present invention relates to the technical field of urea solution injection, and particularly relates to a urea solution injection device for promoting the flow of exhaust gas. Background Art

[0002] The urea solution medium is an aqueous solution with poor lubricating ability. The friction of the moving parts in the injector at the guiding position is significantly greater than the resistance of the fuel injection valve. In addition, the "crystallization" of urea solute often causes the jamming of the armature movable parts. The urea injection system includes air-assisted and non-air-assisted types. Among them, the non-air-assisted urea injection system usually includes a pump, a filter, a metering nozzle connected to the pump, and several sensors, etc. This kind of urea injection system often has very high requirements for the metering nozzle; the air-assisted urea injection system introduces compressed air, but when the equipment works for a long time, it is easy to cause damage to the injection position, affect the flow of the exhaust gas inside the equipment, reduce the effect of the equipment for solution injection. When the solution flows inside the equipment, large particles in the solution are easy to remain inside the equipment, thereby reducing the reaction rate inside the equipment, resulting in incomplete reaction when discharged subsequently. When the solution circulates inside the equipment, the particles are easy to mix together. As the particles gradually accumulate, the flow space inside the equipment decreases, and then blockage occurs inside the equipment, making it easy to cause equipment damage when the equipment continues to be used.

[0003] In summary, when the equipment works for a long time, it is easy to cause damage to the injection position, affect the flow of the exhaust gas inside the equipment, reduce the effect of the equipment for solution injection. When the solution circulates inside the equipment, the particles are easy to mix together. As the particles gradually accumulate, the flow space inside the equipment decreases, and then blockage occurs inside the equipment. Summary of the Invention

[0015] The present invention provides a urea solution injection device for promoting the flow of exhaust gas. It has the following beneficial effects: 1. The urea solution injection device for promoting the flow of exhaust gas is provided with a mounting seat, a treatment tube, and an injector. The solution is added to the treatment tube through the liquid inlet pipe and the injector, so that the solution is mixed when it contacts in the treatment tube. The guide component on the liquid inlet pipe can guide the solution added by the liquid inlet pipe to ensure that the solutions contact each other in the treatment tube. The injector sprays from the side of the treatment tube to avoid damage to the internal components of the treatment tube. The installation is carried out using the movable space generated by the mounting seat and the protective component, so that the device is not easy to be displaced after installation, thereby improving the stability of the overall device after installation. The connection between the discharge component and the treatment tube avoids the residual exhaust gas in the device affecting the pressure inside the device during operation.

[0016] 2. The urea solution injection device that promotes the flow of exhaust gas is provided with multiple guide rods on the diverter cover, so that the guide rods guide the flow of the solution when they contact the solution, thereby reducing the force of the injector spraying the solution. The diverter cover has a groove, and the diverter cover plays a screening effect on the installation sleeve, so that the diverter cover cooperates with the filter plate to intercept large particles in the solution. When the solution flows on the filter plate, it can drive the large particles to converge, avoiding the situation where large particles are scattered on the filter plate and cause blockage.

[0017] 3. The urea solution injection device for promoting the flow of exhaust gas is provided with multiple pressure-bearing plates on the receiving sleeve, so that the pressure-bearing plates can block the falling solution and prevent the solution from falling onto the filter disc and causing excessive impact to affect the filtering effect. When the extrusion block descends, it squeezes the elastic plate. As the elastic plate contracts, the extrusion block approaches the inner support frame, so that the elastic plate can support the extrusion block on the inner support frame.

[0018] 4. The urea solution injection device for promoting the flow of exhaust gas is installed inside the receiving sleeve through the inner support frame and the assembly frame, thereby increasing the stability of the receiving sleeve in the installation position inside the installation sleeve, preventing the receiving sleeve from loosening on the installation sleeve, and keeping the installation positions of the inner support frame and the assembly frame horizontal, so that the inner support frame supports the elastic plate, which is convenient for increasing the supporting effect of the elastic plate on the extrusion block, so that the solution is not easily affected by the drop.

[0019] 5. The urea solution injection device that promotes the flow of exhaust gas discharges the solution and gas through the discharge cavity generated by the confluence shell and the discharge sleeve, so that the solution is not easy to remain when circulating inside the treatment tube, avoiding the residue inside the equipment causing the parts to rust. The circular holes on the surface of the discharge sleeve can circulate gas and liquid, ensuring the convenience of gas flow inside the equipment. At the same time, the discharge sleeve can discharge the solution to different positions.

[0020] 6. The urea solution injection device that promotes the flow of exhaust gas fixes the linkage column in the confluence shell through a fixed ring frame, and the rotation of the rotating blade can accelerate the flow of gas inside the device, preventing the gas from stagnating inside the device for a long time. The linkage column is fixed by the fixed ring frame, so that the linkage column is not easy to tilt, avoiding damage caused by the contact of the exhaust sleeve when the rotating blade rotates.

[0021] 7. The urea solution injection device that promotes the flow of exhaust gas supports the discharge sleeve on the mounting seat through the protective sleeve, thereby ensuring the sealing of the connection position between the discharge sleeve and the protective sleeve, preventing the discharged solution from entering the protective sleeve and affecting the work of the auxiliary frame, and the inner sleeve is supported by the inner plate after installation, which is convenient for the inner sleeve to reinforce the protective sleeve, avoiding the bending or breaking of the protective sleeve during use, and using the elasticity of the buffer seat to reduce shock during movement, avoiding the displacement of the separation sleeve during movement and causing collision.

[0022] 8. The urea solution injection device that promotes the flow of exhaust gas can generate cold air or heat on the support plate as needed through the temperature controller, so as to cool or heat the gas and solution discharged from the exhaust sleeve. When the auxiliary pipe transports cold air, the motor and the separation sleeve can be cooled to avoid the internal temperature rise of the protective tube affecting the work. The reinforcement ring is at the outlet of the auxiliary pipe to prevent the outlet of the auxiliary pipe from being broken or bent due to pressure, thereby affecting the transportation of cold air or heat.

[0023] 9. The urea solution injection device that promotes the flow of exhaust gas is supported by the side support plate while contacting the docking frame through the support plate, so that the support plate and the docking frame form a space for placing the thermostat. The installation position of the side support plate is close to the thermostat, so that the side support plate can reinforce the installation position of the thermostat and maintain the sealing of the connection position between the auxiliary pipe and the thermostat to avoid leakage when the thermostat transports cold air or heat.

[0024] 10. The urea solution injection device for promoting the flow of exhaust gas contacts the liquid inlet pipe and the treatment cylinder through the guide sleeve, so that the solution moves through the diverter plate and drives the vibration block to vibrate. The vibration of the vibration block is used to shake off the particles remaining on the diverter plate, so as to keep the diverter plate clean when diverting the solution, and to accelerate the flow of the solution. The inclined surface of the guide inclined plate is used to guide the falling solution, so that the falling position of the solution is close to the injector, so as to adjust the flow rate of the solution when the two guide inclined plates are close to each other.

[0028] For Example 1, please refer to Figure 1-Figure 15 , the present invention provides a technical solution: a urea solution injection device for promoting the flow of exhaust gas, comprising a liquid inlet pipe 1, The injector 3 is used to inject urea solution. The bottom end of the injector 3 is connected to the treatment cylinder 2. The top of the treatment cylinder 2 is fixedly connected to the liquid inlet pipe 1. The bottom end of the liquid inlet pipe 1 is connected to the guide component 7. The inner surface of the treatment cylinder 2 is fixedly connected to the filter component 8. The bottom end of the treatment cylinder 2 is connected to the discharge component 4. The bottom of the discharge component 4 is fixedly connected to the protection component 5. The bottom of the protection component 5 is fixedly connected to the mounting seat 6. The solution is added to the treatment cylinder 2 through the liquid inlet pipe 1 and the injector 3, so that the solution enters the treatment cylinder 2 from different positions, which is convenient for the solution to mix when it contacts in the treatment cylinder 2, so as to guide the solution when it mixes. The guide component 7 on the liquid inlet pipe 1 can drain the solution added to the liquid inlet pipe 1 to ensure that the solutions contact each other in the treatment cylinder 2. The injector 3 is connected to the treatment cylinder 2 from the bottom end. The treatment tube 2 is sprayed laterally, so that the sprayed solution contacts the solution guided by the flow guide component 7, which can buffer the sprayed solution and avoid damage to the internal components of the treatment tube 2. The mounting seat 6 supports the protective component 5, and the movable space generated by the mounting seat 6 and the protective component 5 is used for installation, so that the equipment is not easily displaced after installation, thereby improving the stability of the overall equipment after installation, and facilitating loading and unloading during the installation process. The discharge component 4 can gather the solution inside the treatment tube 2, which is convenient for the subsequent discharge of the solution and gas, and prevents the residual solution inside the treatment tube 2 from causing damage to the components. The discharge component 4 is connected with the treatment tube 2, so that the exhaust gas flows when the equipment is working, and the residual exhaust gas inside the equipment is prevented from affecting the pressure inside the equipment during operation; ​The filter assembly 8 includes a diverter cover 82, which is used to divert the solution. The top of the diverter cover 82 is fixedly connected with a guide rod 85, the bottom of the diverter cover 82 is fixedly connected with a mounting sleeve 81, the inner surface of the mounting sleeve 81 is fixedly connected with a reset rod 84, the top of the reset rod 84 is fixedly connected with a filter disc 83, and the mounting sleeve 81 is fixedly connected with a receiving frame 86 near the filter disc 83. A plurality of guide rods 85 are arranged on the diverter cover 82 so that the guide rods 85 guide the flow of the solution when contacting the solution, and the guide rods 85 can block the solution of the injector 3, thereby reducing the force of the injector 3 spraying the solution. The diverter cover 82 is provided with a groove, which is convenient for the diverter cover 82 to divert the solution guided by the guide rod 85, so that the solution contacts different positions of the filter disc 83 when entering the interior of the mounting sleeve 81, which is convenient for filtering The plate 83 is tilted due to excessive pressure, and the diverter cover 82 plays a screening role on the installation sleeve 81, so that the diverter cover 82 cooperates with the filter plate 83 to intercept large particles in the solution, which is convenient for large particles to melt after being intercepted. The filter plate 83 is lowered by the pressure of the solution, thereby pressing the reset rod 84 to shrink, so that the filter plate 83 is away from the receiving frame 86. When the pressure on the filter plate 83 is weakened, the reset rod 84 extends to push the filter plate 83 up, and the filter plate 83 stops moving when it contacts the receiving frame 86, so that the receiving frame 86 and the reset rod 84 cooperate to limit the movement range of the filter plate 83. When the solution flows on the filter plate 83, it can drive large particles to converge, avoiding the situation where large particles scatter on the filter plate 83 and cause blockage, so that the activity space inside the installation sleeve 81 is not easily affected by large particles and changes too much.

[0029] The outer surface of the filter disc 83 is slidably connected to the mounting sleeve 81, and the top of the diverter cover 82 extends to the outside of the mounting sleeve 81.

[0030] The top of the inner cavity of the treatment cylinder 2 is fixedly connected to the guide component 7, and the top of the discharge component 4 passes through the treatment cylinder 2 and extends to the interior of the treatment cylinder 2.

[0031] The receiving frame 86 includes an extrusion block 865, the outer surface of which is fixedly connected to a pressure plate 862, and the position of the pressure plate 862 away from the extrusion block 865 is fixedly connected to a receiving sleeve 861, and the pressure plate 862 is provided with a plurality of receiving sleeves 861, so that the pressure plate 862 is subjected to the pressure of the solution to drive the extrusion block 865 to descend, so that the pressure plate 862 can block the falling solution, and prevent the solution from falling onto the filter disc 83 and causing excessive impact force to affect the filtering effect. When the extrusion block 865 descends, it squeezes the elastic plate 866, and as the elastic plate 866 contracts, the extrusion block 865 approaches the inner support frame 863, so that the elastic plate 866 can support the extrusion block 865 on the inner support frame 863, and as the pressure of the solution disappears, the elastic plate 866 extends to drive the extrusion block 865 and the pressure plate 862 to reset, and the receiving sleeve An inner support frame 863 is fixedly connected to the position of 861 near the pressure plate 862, and an elastic plate 866 is fixedly connected to the top of the inner support frame 863.

The circular holes on the surface of the discharge sleeve 43 can circulate gas and liquid, thereby discharging the gas inside the equipment, ensuring the convenience of gas flowing inside the equipment. At the same time, the discharge sleeve 43 can discharge the solution to different positions to avoid affecting the solution discharge.

The linkage column 45 is driven by the motor to rotate through the connecting end 46, so that the linkage column 45 drives the rotating blade 44 to rotate. The wind force generated by the rotation of the rotating blade 44 has a boosting effect on the discharge of gas and solution, and the rotation of the rotating blade 44 can accelerate the flow of gas inside the equipment, preventing the gas from staying inside the equipment for a long time. The fixing of the linkage column 45 by the fixing ring frame 42 makes it difficult for the linkage column 45 to tilt, avoiding the contact of the rotating blade 44 with the discharge sleeve 43 when rotating to cause damage.

The discharge sleeve 43 is supported on the mounting seat 6 through the protective tube 51, and the connection end 46 extends to the inside of the protective tube 51 to contact the motor, thereby ensuring the sealing of the connection position between the discharge sleeve 43 and the protective tube 51, and preventing the discharged solution from entering the protective tube 51 and affecting the work of the auxiliary frame 54. The inner sleeve 53 separates the activity space inside the protective tube 51, so that there is activity space inside the protective tube 51 for gas circulation, and the inner sleeve 53 is supported by the inner plate 55 after installation, which is convenient for the inner sleeve 53 to reinforce the protective tube 51, and avoids the bending or breaking of the protective tube 51 when it is used.

[0036] The inner surface of the protective tube 51 is fixedly connected to the inner sleeve 53, and the top of the auxiliary frame 54 extends to the outside of the separation sleeve 56.

When the auxiliary pipe 545 transports cold air, the motor and the separation sleeve 56 can be cooled, thereby avoiding the internal temperature increase of the protective tube 51 affecting the work. The reinforcement ring 546 is at the outlet of the auxiliary pipe 545, which can increase the bearing capacity of the outlet of the auxiliary pipe 545 to prevent the outlet of the auxiliary pipe 545 from being broken or bent due to pressure, thereby cooling or heating the cold air or heat. The transportation of the auxiliary pipe 545 is affected. The outer surface of the auxiliary pipe 545 is fixedly connected to the docking frame 542. The bottom of the docking frame 542 is fixedly connected to the side support plate 544. The support plate 541 is fixedly connected to the docking frame 542 at a position away from the side support plate 544. The support plate 541 contacts the docking frame 542 and is supported by the side support plate 544. It is convenient for the support plate 541 and the docking frame 542 to form a space for placing the thermostat 543, so that the thermostat 543 is not easy to move after being placed. The installation position of the side support plate 544 is close to the thermostat 543, which is convenient for the side support plate 544 to reinforce the installation position of the thermostat 543. The auxiliary pipe 545 passes through the docking frame 542. The installation position of the auxiliary pipe 545 limits the placement position of the thermostat 543. At the same time, the sealing of the connection position between the auxiliary pipe 545 and the thermostat 543 is maintained to avoid leakage when the thermostat 543 transports cold air or heat.

[0038] The guide assembly 7 includes a guide sleeve 71, a side connecting plate 72 is fixedly connected to the bottom of the inner cavity of the guide sleeve 71, and a guide inclined plate 73 is slidably connected to the side of the side connecting plate 72 away from the guide sleeve 71. Two guide inclined plates 73 are arranged on the side connecting plate 72, and a spring is provided between the two guide inclined plates 73, so that the guide inclined plates 73 are moved by the pressure of the solution, so as to facilitate the adjustment of the distance between the two guide inclined plates 73. When the guide inclined plates 73 move, the inclined surface can be adjusted, and the falling solution is guided by the inclined surface of the guide inclined plates 73, so that the falling position of the solution is close to the injector 3, and the movement of the guide inclined plates 73 is adjusted with the pressure of the solution, so as to facilitate the adjustment of the flow rate of the solution when the two guide inclined plates 73 are close to each other. The inner surface of the guide sleeve 71 is fixedly connected with a diverter plate 74, and the diverter plate 74 is fixedly connected to the inner surface of the guide sleeve 71. The bottom of the disk 74 is fixedly connected with an external ring frame 75, the top of the external ring frame 75 passes through the diverter disk 74 and extends to the inside of the diverter disk 74, and the diverter disk 74 is fixedly connected with a vibration block 76 near the external ring frame 75, which contacts the liquid inlet pipe 1 and the treatment cylinder 2 through the guide sleeve 71, so that the guide sleeve 71 guides the solution, and the diverter disk 74 has an opening to divert the contacted solution, so that the solution drives the vibration block 76 to vibrate when moving through the diverter disk 74, and the vibration of the vibration block 76 is used to shake off the particles remaining on the diverter disk 74, so as to keep the diverter disk 74 clean when diverting the solution, and the vibration blocks 76 are distributed in a circular shape on the diverter disk 74, ensuring that the opening position of the diverter disk 74 is not easily blocked when the vibration block 76 vibrates, so as to accelerate the flow of the solution.

[0039] For Example 2, please refer to Figure 1-Figure 15 , based on Example 1, the present invention provides a technical solution: a method for using a urea solution injection device for promoting the flow of exhaust gas, step 1: injecting urea solution into the treatment tube 2 through the liquid inlet pipe 1 and the injector 3, so that the solution is mixed inside the treatment tube 2, the liquid added by the liquid inlet pipe 1 enters the guide sleeve 71, so that the diverter plate 74 inside the guide sleeve 71 diverts the solution, and the solution drives the vibration block 76 to shake when it falls from the diverter plate 74, and as the solution falls onto the guide inclined plate 73, the guide inclined plate 73 is tilted by the pressure of the solution, and the guide inclined plate 73 slides on the side connecting plate 72 during the tilting process, so that the solution is close to the injector 3 when it enters the treatment tube 2; Step 2: Use multiple guide rods 85 to be set on the diverter cover 82, so that the guide rods 85 can guide the contacted solution. When the solution is on the diverter cover 82, it flows through the groove of the diverter cover 82. When the solution is in the protective tube 51, the receiving sleeve 861 receives the solution inside the protective tube 51, so that when the solution contacts the extrusion block 865 and the pressure plate 862, it presses them down. As the extrusion block 865 descends, it squeezes the elastic plate 866. When the solution stops falling, the extension of the elastic plate 866 pushes the extrusion block 865 to reset, so that the extrusion block 865 drives the pressure plate 862 to reset; Step 3: The filter disc 83 is moved by the pressure of the solution in the installation sleeve 81, and the movement of the filter disc 83 drives the reset rod 84 to contract, so that the filter disc 83 filters the fallen solution. When the pressure on the filter disc 83 is reduced, the reset rod 84 extends and pushes the filter disc 83 to rise in the installation sleeve 81, and stops moving when the filter disc 83 contacts the receiving sleeve 861; Step 4: The gas and solution are discharged through the discharge cavity generated by the confluence shell 41 and the discharge sleeve 43. The confluence shell 41 receives the solution dropped by the installation sleeve 81. The connection end 46 is driven by the motor to rotate, so that the connection end 46 drives the rotating blade 44 to rotate through the linkage column 45, so that the wind force generated by the rotation of the rotating blade 44 discharges the gas to the outside of the discharge sleeve 43, and the linkage column 45 is vertically installed through the fixed ring frame 42; Step 5: Use the protective tube 51 to be installed on the mounting seat 6, and the buffer seat 52 supports the separation sleeve 56. When the equipment is working, the separation sleeve 56 is shaken, so that the buffer seat 52 contracts and drives the separation sleeve 56 to descend, and the inner plate 55 on the separation sleeve 56 slides on the inner sleeve 53. The buffer seat 52 is reset when the shaking is reduced, so that the buffer seat 52 drives the separation sleeve 56 to move upward; Step 6: Use the placement space created by the support plate 541 and the docking frame 542 to place the temperature controller 543, and the support plate 541 and the docking frame 542 move with the separation sleeve 56. When the equipment is working, the temperature controller 543 generates cold air or heat as needed, so that the cold air or heat flows through the auxiliary pipe 545 to the outside near the discharge sleeve 43, so that it heats or cools the discharge of gas and solution.
