Problems solved by technology

Most of the existing automobiles are equipped with exhaust gas treatment devices at the exhaust. Due to the low pressure of the exhaust gas, it is difficult to pass through the exhaust gas treatment device with high resistance. Therefore, a negative pressure fan is usually installed to increase the exhaust gas passing through the exhaust gas treatment device. The pressure of the device will not only increase the cost, but also increase the energy consumption of the fans and supporting systems, that is to say, it will increase the energy consumption while satisfying the purification function.

Embodiment 1

[0028] see Figure 1-4, an energy-saving booster exhaust device for automobile exhaust treatment, comprising a positioning plate 1, a U-shaped conduit 2, a gear sleeve 3, a gear 4, a wind wheel 5, a closed gas cylinder 6, an elastic piston 7, a limit ring plate 8, a gas barrier Disk 9 and connecting arm 101, the middle part of the positioning disk 1 is fixedly provided with a connecting pipe 11, the connecting pipe 11 is set through the positioning disk 1, the inner cavity of the closed air cylinder 6 is used to circulate exhaust gas, one end of the closed air cylinder 6 and one end of the connecting pipe 11 rotate Cooperate and communicate, the closed gas cylinder 6 and the connecting pipe 11 are set coaxially, the rotating shaft 12 and the positioning sleeve 13 are arranged on the positioning plate 1 and close to the outer peripheral wall, and the rotating shaft 12 and the positioning sleeve 13 are distributed at equal intervals in the circumferential direction relative to th...

Embodiment 2

[0030] see Figure 2-4 , and the difference from Embodiment 1 is that the outside of the positioning sleeve 13 is provided with a driving telescopic rod 103, and the outer wall of the connecting pipe 11 is fixedly provided with a positioning shaft 111, and the positioning shaft 111 is rotationally connected with the inner wall of the limit ring disc 8, and the limit ring The outer peripheral wall of the disk 8 is fixedly provided with a lever 81, and one end of the movable lever on the drive telescopic rod 103 is connected with one end of the lever 81 to rotate, that is to say, the movement of the movable lever can drive the limit ring disk 8 to swing, thereby changing its own inclination Angle, it is preferred that the drive telescopic rod 103 is an elastic telescopic cylinder structure and an air intake pipe 1031 is arranged on it, wherein one end of the evenly distributed air outlet pipe 721 is connected to an exhaust pipe 106 through a pipeline, and the positioning plate 1 ...

Embodiment 3

[0032] see Figure 5 , and the difference from Embodiment 1 is that the air blocking disc 9 includes a positioning ring 91 and a roller sleeve 92, the positioning ring 91 and the sliding shaft 105 are fixedly connected, the rolling sleeve 92 is set on the ring shaft of the positioning ring 91, and the rolling sleeve 92 The outer wall is fixed with a sealing plate 921 and teeth 922. The sealing plate 921 is used in conjunction with the positioning ring 91. Under normal conditions, the axis of the sealing plate 921 passes through the ring center of the positioning ring 91, and the teeth 922 mesh with the inner wall of the straight pipe 22. Therefore, when the exhaust gas hits the sealing plate 921, the sealing plate 921 will swing under the restriction of the teeth 922, and the hollow area of ​​the positioning ring 91 will increase, so that the sealing plate 921 will reset. This setting is suitable for exhaust emission pulses case of high frequency.

Abstract

The invention discloses an energy-saving pressurizing emission device for automobile exhaust treatment. The energy-saving pressurizing emission device comprises a positioning disc, a U-shaped guide pipe, a gear sleeve, a gear, a wind wheel, a closed gas cylinder, an elastic piston, a limiting annular disc, a gas blocking disc and a connecting arm. The positioning disc, the U-shaped guide pipe, the gear sleeve, the gear, the wind wheel, the closed gas cylinder, the elastic piston, the limiting annular disc, the gas blocking disc and the connecting arm are arranged, the gas blocking disc, the gear sleeve, the wind wheel, the closed gas cylinder, the elastic piston and the limiting annular disc are core assemblies, and after the gas blocking disc, the gear sleeve, the wind wheel, the closed air cylinder, the elastic piston and the limiting annular disc are combined, weak and small automobile exhaust emission pressure can be increased. The gas flow in an external tail gas purification device can flow smoothly, a draught fan and corollary equipment are not needed, the cost is greatly reduced, and the energy saving effect is achieved.

Description

technical field [0001] The invention relates to the technical field of automobile tail gas treatment, in particular to an energy-saving booster discharge device for automobile tail gas treatment. Background technique [0002] With the increase of the use of automobiles, the emission of exhaust gas is also increasing, and the direct emission of automobile exhaust gas will cause air pollution. Therefore, it is necessary to purify the exhaust gas of automobiles before discharging. Most of the existing automobiles are equipped with exhaust gas treatment devices at the exhaust. Due to the low pressure of the exhaust gas, it is difficult to pass through the exhaust gas treatment device with high resistance. Therefore, a negative pressure fan is usually installed to increase the exhaust gas passing through the exhaust gas treatment device. The pressure of the device will not only increase the cost, but also increase the energy consumption of the fans and supporting systems, that is...
