Description

Technical Field

[0001] The invention relates to the field of exhaust gas treatment, in particular to an exhaust gas treatment device for a diesel-type trackless rubber-tyred vehicle. Background Art

[0002] Fuel vehicles emit a large amount of exhaust gas while driving, which contains hundreds of different compounds. The pollutants include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides. Direct emissions will have a certain impact on the human environment, so the exhaust gas needs to be treated.

[0003] At present, most exhaust gas treatments are carried out using water washing methods. The water washing method is to pass the exhaust gas emitted by the vehicle into the water washing box through the air inlet of the water washing box, let the exhaust gas react with water naturally for treatment, and then discharge it into the atmosphere after purification. However, the exhaust gas is directly discharged after the reaction with water, which makes the contact time between the exhaust gas and water shorter, resulting in insufficient reaction between the exhaust gas and water, insufficient removal of harmful substances in the exhaust gas, and inconvenience for subsequent exhaust gas treatment, which ultimately leads to low exhaust gas treatment efficiency. In addition, the temperature of the discharged exhaust gas is relatively high, which will evaporate part of the water in the water washing box. When there is less water, it is not convenient to fully react with the exhaust gas. Summary of the Invention

[0008] Furthermore, it also includes a breaking up mechanism, which is arranged on the air outlet pipe. The breaking up mechanism includes a breaking up plate, a small torsion spring, a pulling rod and a pushing block. Three breaking up plates are rotatably connected in the air outlet pipe, and a small torsion spring is connected between the three breaking up plates and the air outlet pipe.

[0009] Furthermore, it also includes a scraping mechanism, which is arranged in the ventilation pipe and connected to the filter and the electric push rod. The scraping mechanism includes a scraping rod, a gear and a rack. The scraping rod is rotatably connected in the ventilation pipe, and the scraping rod is in contact with the filter.

[0010] Furthermore, it also includes a water adding mechanism, which is arranged on a curved plate and connected to the treatment box, and the water adding mechanism includes a water tank, a hose, a bent pipe, a blocking block, a return spring, a guide wheel, a steel wire rope, a counterweight block and a buoyancy ring.

[0012] Furthermore, the guide wheel is composed of a fixed column and a circular wheel fixedly connected to the fixed column.

[0013] The beneficial effects are: 1. When the vehicle is started, the exhaust gas will continuously enter the ventilation pipe. The filter in the ventilation pipe can filter the particulate matter in the automobile exhaust. The filtered exhaust gas will enter the treatment box, and then the electric push rod will be started. The telescopic rod of the electric push rod will reciprocate and retract. The reciprocating retraction of the telescopic rod of the electric push rod will make the exhaust gas and water fully mixed. When the gas in the treatment box continues to increase, the gas will make the baffle no longer block the treatment box, and the treated exhaust gas in the treatment box will flow out. Then the large torsion spring will reset the baffle, and the baffle will be reset. When the baffle swings up and down, the treated exhaust gas in the treatment box is intermittently discharged, allowing water and exhaust gas enough time to fully contact. The full contact between water and exhaust gas allows the exhaust gas and water to fully react, so that the exhaust gas discharged by the vehicle can be fully treated, so that the exhaust gas can meet the emission standards and be discharged.

[0014] 2. The upward movement of the treatment box will drive the pull rod to move upward, and the upward movement of the pull rod will cause the shattering plate to swing. When the treatment box moves downward, the shattering plate will swing in the opposite direction and reset. In this way, while the exhaust gas enters the treatment box through the exhaust pipe, the shattering plate will stir the water in the treatment box, so that the water and the exhaust gas can come into contact more fully, and the reaction efficiency of the exhaust gas and water will be accelerated, thereby improving the treatment efficiency of the exhaust gas.

[0015] 3. When the water level in the treatment tank drops, the buoyancy ring will move downward with the drop of the water level, so that the blocking block will no longer block the elbow, and the water in the water storage tank will enter the treatment tank through the hose and the elbow, which can replenish the evaporated water in the treatment tank. As the water level in the treatment tank rises, the buoyancy ring will move upward and drive the counterweight block to move upward. The reset spring will reset and drive the blocking block to move upward, so that the blocking block will block the elbow again. In this way, water can be replenished in time when the water level in the treatment tank drops, so that there is always enough water in the water storage tank to fully react with the exhaust gas of the vehicle.

[0027] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and drawings. The specific connection methods of each part adopt conventional means such as bolts, rivets, welding, and bonding in the existing technology, which will not be described in detail here.

[0028] Example 1: An exhaust gas treatment device for a diesel-type trackless rubber-tyred vehicle, such as Figures 1-6 、 Figure 8 and Figure 10As shown, it includes a carriage 1, a mounting frame 2, mounting screws 3, an arc plate 4, a flushing mechanism, a vent pipe 61, a filter 611, a collection box 62, an outlet pipe 63, a one-way valve 64 and a delay mechanism. The mounting frame 2 is provided with a number of threaded holes, and the carriage 1 is also provided with a number of threaded holes. The carriage 1 is connected to the mounting frame 2 by four mounting screws 3, and the mounting frame 2 is connected to the arc plate 4 by bolts. The flushing mechanism is provided on the carriage 1 and is connected to the carriage 1. The mounting frame 2 is connected to the arc plate 4, and an air outlet pipe 63 is provided on the evenly flushing mechanism. The air outlet pipe 63 is connected to the air vent pipe 61 by bolts. The air outlet pipe 63 is communicated with the air vent pipe 61. A filter screen 611 is connected to the air vent pipe 61 by rivets. A collecting box 62 is placed at the bottom of the air vent pipe 61. The air vent pipe 61 is communicated with the collecting box 62. A one-way valve 64 is connected to the air outlet pipe 63 by bolts. The delay mechanism is provided on the evenly flushing mechanism.

[0029] The flushing mechanism includes a mounting seat 51, an electric push rod 52, a processing box 53 and a slide rail 54. The bottom of the carriage 1 is connected to the mounting seat 51 by bolts, the top of the mounting seat 51 is connected to the electric push rod 52 by bolts, the telescopic rod of the electric push rod 52 is connected to the processing box 53 by bolts, and the processing box 53 is connected to the air outlet pipe 63 by bolts. The side of the processing box 53 close to the carriage 1 is slidably connected to the slide rail 54, and the slide rail 54 is connected to the bottom of the mounting frame 2 by bolts.

[0030] The delay mechanism includes a baffle 71, a large torsion spring 72, a limit plate 73, an upper magnet 74 and a lower magnet 75. The baffle 71 is rotatably connected to the processing box 53. Two large torsion springs 72 are connected between the baffle 71 and the processing box 53 by hooks. The two large torsion springs 72 are symmetrically arranged. The limit plate 73 is connected to the processing box 53 by bolts. The bottom of the baffle 71 is connected to the upper magnet 74 by bolts, and the top of the limit plate 73 is connected to the lower magnet 75 by bolts. The magnetic properties of the upper magnet 74 and the lower magnet 75 are opposite, and the upper magnet 74 and the lower magnet 75 attract each other.

[0031] When the exhaust gas is discharged from the exhaust pipe 61, the filter 611 in the exhaust pipe 61 can filter the particulate matter in the exhaust gas of the vehicle. The filtered exhaust gas enters the exhaust pipe 63 through the exhaust pipe 61 and then enters the exhaust box 53 through the exhaust pipe 63. Then, the electric push rod 52 is started, and the telescopic rod of the electric push rod 52 is reciprocated. The reciprocating reciprocating reciprocating rod of the electric push rod 52 drives the treatment box 53 to move up and down. The reciprocating movement of the treatment box 53 can fully mix the exhaust gas with the water. When the exhaust gas continuously enters the treatment box 53 through the exhaust pipe 61 and the exhaust pipe 63, the gas in the treatment box 53 is continuously increased. When the gas in the treatment box 53 is large, the thrust of the gas is greater than the torsion of the large torsion spring 72. The gas will make the baffle 71 When the lever 74 is in the unlock position, the lever 74 is in the unlock position, and the locking cam 73 is in the unlock position, so that the locking cam 73 is locked.

[0032] Example 2: Based on Example 1, Figure 4 、 Figure 6 and Figure 7 As shown, a breaking mechanism is also included, which is arranged on the air outlet pipe 63. The breaking mechanism includes a breaking plate 81, a small torsion spring 83, a pulling rod 84 and a pushing block 85. Three breaking plates 81 are rotatably connected in the air outlet pipe 63. Small torsion springs 83 are connected between the three breaking plates 81 and the air outlet pipe 63 through hooks. A pulling rod 84 is slidably connected to the air outlet pipe 63. The bottom of the pulling rod 84 is connected to the pushing block 85 by bolts. The breaking plate 81 is located above the pushing block 85.

[0033] The upward movement of the processing box 53 will drive the pulling rod 84 to move upward, and the upward movement of the pulling rod 84 will drive the pushing block 85 to move upward. The upward movement of the pushing block 85 will push the breaking plate 81 to swing, causing the small torsion spring 83 to be twisted. When the processing box 53 moves downward, the processing box 53 will drive the pulling rod 84 to move downward, and the downward movement of the pulling rod 84 will drive the pushing block 85 to move downward. The small torsion spring 83 will reset, thereby driving the breaking plate 81 to swing in the opposite direction and reset. In this way, when the exhaust gas enters the processing box 53 through the exhaust pipe 63, the breaking plate 81 will stir the water in the processing box 53, so that the water and the exhaust gas can be in more complete contact, and the reaction efficiency of the exhaust gas and water is accelerated, thereby improving the treatment efficiency of the exhaust gas.

[0034] Example 3: Based on Example 2, Figure 4 and Figure 5 As shown, a scraping mechanism is also included, which is arranged in the ventilation pipe 61 and connected to the filter 611 and the electric push rod 52. The scraping mechanism includes a scraping rod 92, a gear 93 and a rack 94. The scraping rod 92 is rotatably connected in the ventilation pipe 61, and the scraping rod 92 is in contact with the filter 611. The end of the scraping rod 92 close to the electric push rod 52 is connected to the gear 93 through a flat key, and the bottom of the pushing block 85 is connected to the rack 94 by bolts, and the gear 93 and the rack 94 are engaged.

[0035] When the push block 85 moves upward, it will drive the rack 94 to move upward. The upward movement of the rack 94 will engage with the gear 93, causing the gear 93 to rotate. The rotation of the gear 93 will drive the scraper rod 92 to rotate. The rotation of the scraper rod 92 can scrape off the impurities on the filter 611. The scraped impurities will fall into the collection box 62. Scraping off the impurities allows the filter 611 to better filter the vehicle exhaust, which can facilitate the subsequent treatment of the vehicle exhaust, thereby further improving the vehicle exhaust treatment efficiency.

[0036] Example 4: Based on Example 3, Figures 8-10As shown, it also includes a water adding mechanism, which is arranged on the curved plate 4 and connected to the processing box 53. The water adding mechanism includes a water tank 101, a hose 102, a bend 103, a blocking block 104, a return spring 105, a guide wheel 106, a wire rope 107, a counterweight 108 and a buoyancy ring 109. The curved plate 4 is connected to the water tank 101 by bolts, and the bottom of the water tank 101 is connected to the hose 102 by bolts. The hose 102 is connected to the water tank 101, and the bottom of the hose 102 is connected to the bend 103 by bolts. The bend 103 is connected to the hose 10 2 is connected, a blocking block 104 is slidably connected to the curved pipe 103, a return spring 105 is connected between the blocking block 104 and the curved pipe 103 via a hook, a guide wheel 106 is bolted to the inner wall of the processing box 53, and the guide wheel 106 consists of a fixed column and a round wheel fixedly connected to the fixed column, one end of a steel wire rope 107 is bolted to the blocking block 104, and the other end of the steel wire rope 107 is bolted to a counterweight 108, the steel wire rope 107 passes around the guide wheel 106, and a buoyancy ring 109 is bolted to the counterweight 108.

[0037] Initially, the buoyancy ring 109 floats on the water surface in the treatment box 53, and the blocking block 104 blocks the elbow 103. When the vehicle is started and the heated exhaust gas is discharged into the treatment box 53 and contacts the water, the high temperature of the exhaust gas will evaporate a portion of the water in the treatment box 53. When the water in the treatment box 53 becomes less and the water level drops, the buoyancy ring 109 will move downward as the water level drops. The downward movement of the buoyancy ring 109 will drive the counterweight block 108 to move downward. The downward movement of the counterweight block 108 will pull the wire rope 107 downward. The downward movement of the wire rope 107 will drive the blocking block 104 to move downward, and the return spring 105 will When the water level in the treatment tank 53 rises, the buoyancy ring 109 moves upward and drives the counterweight 108 to move upward, and the reset spring 105 resets and drives the blocking block 104 to move upward, so that the blocking block 104 blocks the elbow 103 again. In this way, water can be replenished in time when the water level in the treatment tank 53 drops, so that there is always enough water in the water tank 101 to fully react with the exhaust gas of the vehicle.

[0038] Example 5: Based on Example 4, Figure 4 、 Figure 6 and Figure 7As shown, it also includes a rotating rod 111 and a mounting plate 112, wherein one of the scattering plates 81 is rotatably connected to a plurality of rotating rods 111, and each of the rotating rods 111 is connected to two mounting plates 112 by bolts, and the two mounting plates 112 on each rotating rod 111 are symmetrically arranged.

[0039] The swinging of the breaking plate 81 will stir the water in the treatment box 53. The stirred water will cause the rotating rod 111 to rotate. The rotation of the rotating rod 111 will drive the mounting plate 112 to rotate. The rotation of the mounting plate 112 can fully stir the water in the treatment box 53, so that the water and the vehicle exhaust can further fully contact each other, thereby further accelerating the reaction efficiency of the vehicle exhaust and water, and further improving the treatment efficiency of the vehicle exhaust.
