Background technique

Since environmental protection department's proposition of various countries is further reduced the nitrogen oxide pollutant that diesel emission is put.It is domestic It is commonly called as Europe IV standard.Engine production quotient begins to use SCR technology (Selective Catalytic Reduction Technology SCR technology) reach the requirement of environmental protection administration.(country is commonly called as diesel engine vent gas treatment fluid Are as follows: automobile urea, urea for vehicle, automobile environment-protection urea), it is the consumables for having to use in SCR technology.

Currently, the capacity and urea consumption of commercial diesel vehicle urea tank are different, we are with the most common heavy type For tractor.General heavy hauler urea tank design capacity 40L, can start to alarm lower than capacity 10%.Tractor urine Plain consumption is about hundred kilometers of 3.5L.By conversion it is found that substantially every 1000 kilometers of traveling just needs to add a urea.Now Truck high-velocity stream transports daily operating range in 800km-1500km etc., so requiring to add primary urine daily substantially Element, for truck user, urea addition is a daily repetitive operation.

Currently, commercial diesel vehicle urea is mostly 10Kg barreled specification.Urea addition manner is the modeling worn by urea bucket Material filling conduit addition, specific steps are as follows:

1. installation conduit: removing urea bung, plastic catheter is locked in urea bung hole.

2. intubation: plastic catheter outlet is placed in urea tank filler.

3. urea fills: lifting urea bucket smoothly flows out urea, maintained until urea adds in bucket.

4. filling it up with: the step of repeating 1-3, until having urea spilling in urea tank.

In conjunction with above-mentioned actual mechanical process and Fig. 1, by shortcoming existing for existing filling tool and dosing method It is illustrated:

1, urea bucket is designed without air inlet, and the filling time is partially long: it can be seen that, filling urea, urine by plastic catheter by Fig. 1 Urea in plain bucket is flowed out by conduit, and after urea outflow is a certain amount of, inner space is formed as shown in Figure 1 at vacuum state Negative pressuren zone causes remaining urea that cannot smoothly flow out out of bucket.For the urea tank for cooperating a plurality of vehicles, filling conduit mouth design It is thinner, cause the discharge of urea in urea bucket difficult.Complete a vehicle about 40L urea filling at least need 20 minutes with On.Operator needs to hold urea bucket for a long time and adjusts position, and operation convenience is very poor.

2, filling conduit is easy to fall off: filling tool conduit portion is extension type plastic screwed pipe, is filled with urea tank The connection type of mouth is to be inserted freely into plug-in, and the shape of plastic tube is low with rigidity to lead to its connecting and fixing property with filler Difference easily leads to plastic tube and filler in filling process and is detached from, urea addition is caused to interrupt, is unrestrained.Fill conduit and urea bucket Screw thread is connected as to tighten, it is since conduit is plastic material and relatively soft, easily-deformable, it is not connected firmly in actual use with urea bucket Gu when have a conduit obscission, urea is unrestrained, pours operator and causes to waste, user is caused to complain.

3, process is cumbersome: in adding procedure, conduit will be reconnected by often adding one barrel of urea, time-consuming and laborious.

4, it fills it up with no prompt: not filling it up with prompt facility when filling, filling can just stop filling until urea overflows every time, The urea of spilling can also form crystallization in urea tank, while cause the waste of urea.

5, when filling, need to fill the posture that personnel lift urea bucket and remain urea bucket opening mouth down, very It is easy fatigue.

Embodiment 1

The port length of the funnel projecting tube is 90mm, and the taper of the conical surface is 1:10.

The length of the exhaust pipe 1 is greater than the port of funnel projecting tube.

A kind of principle of quick adding set of commercial vehicle urea of the utility model is as follows:

1, the present invention is that urea adds fastening means, connect positioning with urea tank filler by the conical surface in tool bottom end；

2, tool facilitates crawl and fixation equipped with handrail；

3, tool interior devises exhaust pipe, and exhaust is kept apart with feed liquor, avoids interfering with each other.

4, it is bent downwardly at the top of exhaust pipe, avoids thering is liquid to enter exhaust pipe from top to bottom when addition urea；

5, input duct angle is consistent with urea tank filler angle, ensure that the level of upper end funnel；

6, when filling, liquid level and liquid level difference in lower channel are h in the funnel of upper end.Since urea liquid is substantially without viscous Thick retardance, so can be approximate according to acceleration of gravity formula V²=2gh can calculate urea muzzle velocity V.Gone out again by pipeline The relation formula Q=SV of mouth sectional area S and speed, flow, can be calculated maximum stream flow is 0.3L/s, so adding one barrel of 10Kg The urea of the specification theoretical used time is 30s or so.It is influenced in view of actual mechanical process will receive various factors, so adding one barrel Real time is within 40s.In view of need not frequently install plastics sebific duct when filling, so the time of each car filling process is not It can be more than 5 minutes, compared to original charging method, speed improves 3 times or more, has saved the plenty of time, reduces personnel's body Power consumption.

7, inventive article specially devises dependency structure for prompt is filled it up with, and is illustrated in conjunction with attached drawing 2:

In normal filling process, when liquid level is lower than liquid level N in urea bucket, feed pathway feed liquor, exhaust passage exhaust, this When urea flow it is larger.As liquid level gradually rises in urea bucket, when reaching at liquid level N, exhaust pipe mouth is lower than liquid level, urinates at this time Plain atmosphere in the tub can not continue through gas vent discharge, can only be discharged by feed pathway, just will appear feed liquor and exhaust is mutual The case where interference, flow of urea quantitative change is slow, and generates larger exhaust sound simultaneously, should be slowly added urea at this time.Continue filling and works as liquid When face is reached at M, filler is lower than urea liquid level, and atmosphere in the tub can not be discharged.Exhaust sound disappears at this time, should stop adding immediately Note.Otherwise, liquid level can quickly reach the face L, and be flowed out by filler, cause to waste.To sum up, filling it up with prompt facility can summarize Are as follows: quickly filling starts slowly filling until exhaust sound disappears, after exhaust sound disappears until there is exhaust sound, after there is exhaust sound Show that urea has been filled it up with, should stop filling immediately；
