Description
Technical field
The present invention relates to a kind of electrical equipment control technology, particularly regeneration controller for particle trapper of diesel engine.
Background technique
Owing to contain a large amount of soot particle (PM), the black smoke environmental pollution of discharging is serious in the exhaust gas from diesel vehicle, and health is constituted harm.The way that solves is to install particle trapper additional, on the filter core of catcher, makes the tail gas that emits reach environmental protection requirement the micro particle catching in the tail gas.Particulate on filter core reaches a certain amount of, during the motor cisco unity malfunction, filter core is changed remove, and just can reuse.This sweep-out method expends man-hour, and out of service could the replacing of vehicle need, influences the normal transport operation.
Summary of the invention
The technical issues that need to address of the present invention are a kind of regeneration controller for particle trapper of diesel engine of design, when the particulate on the catcher filter core reaches a certain amount of and influences the motor proper functioning, can automatically the carbon granules on the catcher filter core and other particulates be removed, make filter core recover normal work.Technological scheme of the present invention is, a kind of diesel car exhaust micro particle catching device regenerating control device, it is characterized in that: the two ends of relay switch J2-1K and the series circuit of resistance wire R are connected with power supply, the two ends of the time relay normally closed switch SJ1-1B and the series circuit of relay J 1 are connected with power supply, are connected to two pressure switch Y-1K that are in parallel and relay normally open switch J1-1K on above-mentioned SJ1-1B and the circuit between the J1; Time relay normal open switch SJ2-1K is connected with power supply with the two ends of the series circuit of tonifying Qi solenoid valve DF2; The two ends of bypass solenoid valve DF1 are connected with power supply; Relay J 2 is connected with power supply with the two ends of the series circuit of time relay normally closed switch SJ3-1B, the two ends of time relay sj 1, SJ2 and SJ3 are connected with power supply respectively, are connected in series relay normally open switch J1-2K on the circuit between SJ2-1K and the positive source.Be in series with R in being close on the circuit of road of resistance wire R
1With tutorial light LED1.Between resistance R 3 and zero-power line, be provided with tutorial light.The present invention is owing to adopted pressure switch, resistive heater that regeneration thermal source and control unit are provided, thereby the present invention has the remarkable advantage of automaticity height, favorable regeneration effect compared with the prior art.
Description of drawings
Accompanying drawing is an electrical schematic diagram of the present invention.
Embodiment
In conjunction with above-mentioned accompanying drawing regenerating control device of the present invention is described in detail, the two ends of relay switch J2-1K and the series circuit of resistance wire R are connected with power supply, the series circuit of resistance R 1 and burner on light LED1 and resistance wire R are in parallel, the two ends of the time relay normally closed switch SJ1-1B and the series circuit of relay J 1 are connected with power supply, are connected to the normal open switch J1-1K of three hand switch K, pressure switch Y-1K that are in parallel and relay J 1 on above-mentioned SJ1-1B and the circuit between the J1; On the cathode circuit of power supply, be connected to a relay switch J1-2K; The two ends of resistance R 2 and the series circuit of bypass tutorial light LED2 are connected with J1-2K with the negative pole of power supply respectively; The two ends of time relay normal open switch SJ2-1K, resistance R 3 and the series circuit of tonifying Qi tutorial light LED3 are connected with J1-2K with the negative pole of power supply respectively, and the series circuit of tonifying Qi solenoid valve DF2 and resistance R 3 and tonifying Qi tutorial light LED3 is in parallel; The two ends of bypass solenoid valve DF1 are connected with J1-2K with the negative pole of power supply respectively; The two ends of relay J 2 and the series circuit of time relay normally closed switch SJ3-1B are connected with J1-2K with the negative pole of power supply respectively, the two ends of time relay sj 1, SJ2 and SJ3 are connected with J1-2K with the negative pole of power supply respectively, SJ3 is used for controlling heating time, can in 0-60 scope second, set, SJ2 is used for controlling the tonifying Qi time, can set in second at 0-30, SJ1 is used for controlling the total process time of regeneration, can set in 0-10 minute.Can be connected in series a circuit protecting switch on the power supply.
Control principle of the present invention: connect vehicle power, when filter core stops up serious, when the diesel exhaust gas back pressure reaches 20Kpa, Y-1K closure, J1 energising, so J1-1K and J1-2K closure, connect bypass solenoid valve DF1, the rotation of cylinder action drives plate washer is closed the filter core gas circuit and open and is close to the road pipe, and bypass is opened, tail gas flows out from bypass, and the bypass tutorial light is bright simultaneously; Relay J 2, time relay sj 3, SJ2, SJ1 connect at this moment, thereby make the J2-1K closure, and resistance wire begins heating, burner on light is bright, SJ2-1K closure after 30 seconds, aeration valve DF2 connects, and tonifying Qi begins, tutorial light is bright simultaneously, after 60 seconds kinds, SJ3-1B disconnects, and finishes the resistance wire heating, burner on light goes out, and heating is finished; SJ1-1B disconnects after 10 minutes, thereby J1 is disconnected, and this moment, control circuit all disconnected, and finished the overall process of particle trapper thermal regeneration.When pressure switch K contingency was malfunctioning, also available hand switch started the above-mentioned work of finishing.
