Abstract
The utility model discloses an automobile exhaust gathering and processing device which is controlled by a start switch, wherein the start switch is connected with a pneumatic clamping mechanism through an electromagnetic valve, the pneumatic clamping mechanism is connected with a tail pipe, and a filter screen and a urea injection system behind the pneumatic clamping mechanism are both connected with the exhaust gathering and processing device. In the utility model, according to the pneumatic control principle, a pneumatic clamping way is adopted, an electromagnetic valve is controlled by operating and starting the electrical switch to output signals so as to achieve the fast automatic clamping function of the exhaust gathering device; since the commonly-used tail pipes are various in calibre, the universality of the exhaust gathering device is improved, the inner wall of a trumpet-shaped connector of the exhaust gathering device is made into a step shape so as to be butted with tail pipes with different calibres, and the tightness is better; and chemical reaction processing to collected exhaust can be performed by using automobile urea, and the emission of pollution in waste gas can be reduced. The automobile exhaust gathering and processing device is convenient to operate, saves time and labor, and conforms to environmental protection requirements.
Description
Technical field
The utility model relates to and belongs to vehicle exhaust Collecting and dealing field, especially gathering-device clamping mode and vent gas treatment technical elements.
Background technology
Auto assembly is joined assembly line under factory's car load, ato unit, starts first to discharge billowing black smoke; Just can in the workshop, spread like untimely processing, the severe contamination working environment with influence workers ' health, adopt armstrong's patent to be clamped in the exhaust pipe mouth of engine exhaust system mostly and have the vehicle exhaust gathering-device now; Sometimes need two people's cooperations just can clamp, waste time and energy, efficient is lower; And poorly sealed, interface position leakiness gas, the waste gas of collecting are untreated usually just directly to be entered in the atmosphere outside the workshop through pipeline; Contaminated environment does not meet the requirement of national energy-saving and emission-reduction yet.
The utility model content
For remedying the deficiency of prior art, the utility model provides a kind of vehicle exhaust collection and treatment device.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of vehicle exhaust collection and treatment device; It is controlled by starting switch, and starting switch is connected with pneumatic pinch mechanism through magnetic valve, cylinder, and pneumatic pinch mechanism is connected with tailpipe; Screen pack after the pneumatic pinch mechanism is connected with the exhaust collection treating apparatus, the urea-spray system also with the exhaust collection treating apparatus be connected.
Said pneumatic pinch mechanism comprises cylinder, and cylinder is provided with push rod, and push rod is connected with intermediate supports through STATEMENT OF FEDERALLY SPONSORED, and intermediate supports is connected with clamping to pitch, and the end that clamping is pitched contacts with fixed contact point.
Said urea-spray system comprises the pressure sensor that is located at exhaust collection treating apparatus porch, and pressure sensor is connected with electromagnetic pump through relay, and electromagnetic pump is connected with urea box; Said electromagnetic pump also is connected with bubbler, and bubbler is located at the device portal place, and is positioned at the pressure sensor below.
The interface of said tailpipe is a trumpet type, and the interface inwall becomes stepped, is complementary with multiple tailpipe caliber commonly used.
The utility model is according to the pneumatic control principle; Adopt the pneumatic pinch mode; On armstrong's patent clamping device basis, improve, increase pneumatic actuator-cylinder, realize the function of the fast automatic clamping of tail gas collecting device through operation start electric switch control magnetic valve output signal; Because tailpipe commonly used has multiple bore, be the versatility that improves tail gas collecting device, its trumpet type interface inwall is made stepped, dock different bore tail pipes, better tightness; The tail gas of collecting adopts automobile urea (state's four dischargings) to carry out chemical reaction and handles, and reduces the discharging of pollutant in the waste gas.
Beneficial effect: the utility model is easy to operate, and is time saving and energy saving, compliance with environmental protection requirements.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein: 1 starting switch, 2 electric wires, 3 magnetic valves, 4 tracheaes, 5 cylinders, 6 intermediate supports; 7 clamp fork, 8 fixed contact points, 9 screen packs, 10 pressure sensors, 11 relays, 12 electromagnetic pumps; 13 urea boxes, 14 bubblers, 15 tailpipes, 16 cylinder push-rods, 17 STATEMENT OF FEDERALLY SPONSORED.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the utility model structural representation, mainly contains two parts and forms: pneumatic pinch mechanism, urea-spray system.Pneumatic pinch mechanism is that cylinder push-rod seesaws, and converts rotatablely moving of intermediate supports 6 (there is screw thread the middle part, with the screw thread coupling on this device case) into; Drive to clamp on the fork 7 and move; Its preceding terminal contacts combines with fixed contact point 8 to clamp, and motion is placed on the comprehensive panel of gathering-device by starting switch 1 control; Starting switch 1 is connected with magnetic valve 3 through electric wire 2; Magnetic valve 3 is connected with cylinder 5 through tracheae 4, and whether cut-offfing in the control cylinder 5 of magnetic valve 3 ventilates, and whether control device clamps then; The urea-spray system is made up of urea box 13, electromagnetic pump 12 and bubbler 14, pressure sensor 10 and relay 11; In device, spray urea automatically according to tail gas pressure; Redox reaction just takes place in automobile urea and nitrogen oxide in this device, generate free of contamination nitrogen and steam and discharge.
In this structure, tubaeform interface is processed by the high-temperature resistant rubber material, combines through clamp mechanism with tailpipe 15; Screen pack 9 is installed in tubaeform interface rear end, and the larger particles such as flue dust in the pre-flock exhaust waste gas are avoided pressure sensor 10 and bubbler 14 to block and lost efficacy; Source of the gas is auxiliary with in the gas gas receiver from car load, compressed air pressure 0.55-0.8 MPa; When operating personnel are put into tailpipe 15 in the collection mouthful clamping fork 7, press starting switch 1, magnetic valve 3 energisings; Compressed air just gets in the cylinder 5 through magnetic valve 3 from gas receiver; Cylinder push-rod 16 is rectilinear motion forward just, through STATEMENT OF FEDERALLY SPONSORED 17, just is converted into the elevation movements of intermediate supports 6; Terminal contacts combine clamping before drive clamping fork 7 with fixed contact point 8, gathering-device just with tailpipe 15 fastening butt joints; When the ato unit exhaust; The pressure sensor 10 perception pressures at expulsion of the porch through placing tail gas collecting device; Pressure sensor 10 output voltages drive 12 work of relay 11 control electromagnetic pumps, start the electromagnetic pump 12 of urea-spray system, and absorption urea spray in the gathering-device through injector 14 from urea box 13; With the redox reactions such as nitride in the waste gas, the pollutant of generation enters in the atmosphere.When car load rolls off the production line, close starting switch 1, magnetic valve 3 outage venting, cylinder 5 returns clamp fork 7 and unclamp, and take off gathering-device from tailpipe, and urea-spray is also regulated until stopping urea-spray according to the exhaust situation automatically.
