Description
Technical Field
The utility model relates to a DPF assembly technical field among the diesel engine exhaust treatment especially relates to a thermocouple sensor installs and removes convenient DPF assembly.
Background
The emission standard of automobile exhaust is gradually strict, and the technical route of aftertreatment is continuously updated. The technical route adopted by the existing diesel oil post-treatment is DOC + DPF + SCR + ASC, wherein the ratio of the regeneration of the DPF to the temperature calibration workload is large and is particularly complex. When the temperature of the DPF is calibrated, under the condition that a carrier is not damaged, at least 8-10 thermocouples are inserted into each area inside the DPF to acquire temperature distribution.
The conventional method is to insert the thermocouple into the DPF carrier first and then weld the rear end cap, or to insert the thermocouple into the carrier by punching a hole in the rear end cone. Both of these methods have drawbacks: firstly, the DPF is required to be frequently disassembled due to calibration, and the thermocouple is inconvenient to disassemble, so that the thermocouple is easily broken and loss is caused; secondly, because the carrier hole position can not be directly seen, the thermocouple is inconvenient to insert into the DPF carrier, and the carrier is easy to damage.
SUMMERY OF THE UTILITY MODEL
To defect and not enough problem among the prior art, the utility model provides a thermocouple sensor installs and removes convenient DPF assembly has designed and has linked up the barrel and adopt the flange formula to dismantle the connection, through clamp quick fixation, easy dismounting increases thermocouple sensor's fixing base moreover to make things convenient for thermocouple sensor's accurate installation and dismantlement, favourable protection thermocouple is not fragile at the dismouting in-process.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a thermocouple sensor installs and removes convenient DPF assembly, includes the end of giving vent to anger awl, links up barrel, inlet end awl barrel and clamp, the end of giving vent to anger awl, link up the barrel and connect gradually with the inlet end awl barrel, its junction is equipped with the assorted flange respectively and links up, and the flange outside of linking is fixed through the clamp, it is used for installing the fixing base of thermocouple sensor to be equipped with a plurality of groups on the barrel circumference to link up.
Furthermore, a DPF carrier is arranged in the air inlet end cone cylinder body.
Furthermore, the center of the fixed seat is provided with a mounting hole.
Furthermore, the fixed seat is an integral large and small concentric cylinders, and the small cylinder section is fixed in the connecting cylinder body.
Furthermore, the number of the fixing seats is 8-10 groups.
Furthermore, except the head and the tail of the fixing seat, the other adjacent fixing seats are uniformly arranged at intervals.
The utility model discloses following beneficial effect has: the utility model adopts the flange connection of the linking cylinder body, the air outlet end cone and the air inlet end cone cylinder body, and the connection is quickly fixed by the clamp, and the disassembly and the assembly are quick and convenient; therefore, the thermocouple sensor can be effectively and accurately installed on the DPF carrier positioned in the air inlet end conical cylinder, deviation does not occur in the installation position, and the risk of damaging the carrier is reduced; and a thermocouple sensor fixing seat is added on the connecting cylinder body, so that the installation of the thermocouple sensor is more convenient.

fig. 3 is the schematic view of the thermocouple sensor of the present invention installed on the DPF carrier and the fixing base.
Detailed Description
The following describes in detail embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 1-3: the utility model provides a thermocouple sensor installs and removes convenient DPF assembly, includes that the end of giving vent to anger bores 1, links up barrel 2, inlet end awl barrel 3 and clamp 4, the end of giving vent to anger bores 1, links up barrel 2 and inlet end awl barrel 3 and connects gradually, and its junction is equipped with assorted flange 10 respectively and links up, and the flange 10 outside that links up is fixed through clamp 4, it is used for installing thermocouple sensor 101 to link up to be equipped with a plurality of groups on 2 circumferences of barrel 21.
The DPF carrier 31 is arranged in the air inlet end cone 3.
The center of the fixed seat 21 is provided with a mounting hole for mounting the thermocouple sensor 101.
The fixed seat 21 is an integral large and small concentric cylinders, and the small cylinder is fixed in the connecting cylinder.
The number of the fixing seats is 8-10 groups.
Except the head and the tail of the fixed seat 21, other adjacent fixed seats are uniformly arranged at intervals.
Specifically, when DPF temperature calibration, loosen the clamp earlier, pull down the end awl of giving vent to anger and link up the barrel, the removal of the end awl of giving vent to anger, for convenient follow-up good observation when inserting the DPF carrier with the thermocouple, it is good to be difficult for inserting wrong position, makes bad the carrier. Then install thermocouple sensor one end in the fixing base that links up the barrel earlier, insert the other end in the hole that needs the temperature measurement position of the DPF carrier that is located inlet end awl barrel inside again, then will link up the barrel and assemble with inlet end awl barrel through the flange, fix by the clamp, will give vent to anger the end awl and install on linking up the barrel at last.
The utility model discloses can be more effective accurate installation thermocouple, the deviation can not appear in the mounted position, has reduced the risk of destroying the carrier. And the thermocouple is fast and convenient to disassemble and assemble and is not easy to damage.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. The present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only for illustrating the principle of the present invention, and the present invention will have various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements all fall into the scope of the present invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
