Description

Novel integral type urea filter

Technical Field

The utility model relates to a filter technical field specifically is a novel integral type urea filter.

Background

To meet emission standards, it is desirable to reduce engine nitride NOX emissions by SCR technology. In the whole SCR exhaust gas after-treatment system, the diesel exhaust gas treatment fluid is a consumable product which must be used in the SCR technology. In an SCR system for treating exhaust gas, a urea filter needs to be installed because the accuracy of a nozzle for atomizing and spraying an aqueous urea solution is required to be high.

Because urea solution concentration is high when the urea filter needs to solve low temperature to easy crystallization leads to the frozen inflation of urea solution and damages the phenomenon of filter casing, consequently, needs a neotype integral type urea filter.

SUMMERY OF THE UTILITY MODEL

The utility model provides a novel integral type urea filter, technical problem that exists in can the above-mentioned background of effectual solution.

In order to achieve the above object, the present invention provides the following technical solutions:

the utility model provides a novel integral type urea filter, including casing, filter core, be equipped with in the casing and filter the cavity, the filter core is established in the filter cavity and will filter the cavity and separate for the feed liquor chamber that lies in outside the filter core of mutual isolation and the play liquid chamber that lies in the filter core, be equipped with double-deck frost resisting element between the inner wall of filter core and casing, double-deck frost resisting element is including bush, buffering withstand voltage cover, the inner wall integrated into one piece of buffering withstand voltage cover and casing, buffering withstand voltage cover is hugged closely to the bush, ventilative valve is installed in the embedding of bottom center department of casing, adopt O type circle to seal between the bottom of ventilative valve and casing.

Preferably, the buffer pressure-resistant sleeve is made of PU material.

Preferably, the housing is made of a plastic material.

Preferably, the ventilation valve is made of a plastic material.

Preferably, the bushing is made of a rubber material.

The beneficial effects of the utility model reside in that:

the utility model has the advantages that the buffering pressure-resistant sleeve is integrated with the inner wall of the shell, the structure is simple and reliable, and the cost is low; through the combination of the bush and the buffering pressure-resistant sleeve, the damage to the shell caused by the icing and expansion of the urea solution at low temperature can be effectively avoided. The utility model relates to an it is ingenious, increased economic nature and long-term effect.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

FIG. 1: the utility model discloses the schematic structure.

FIG. 2: the utility model discloses local structure schematic diagram.

In the figure: 1. the filter comprises a shell, 2, a filter element, 4, a buffer pressure-resistant sleeve, 5, a lining, 6, a ventilation valve, 7, an O-shaped ring, 8, a liquid inlet cavity, 9 and a liquid outlet cavity.

Detailed Description

The embodiments of the invention will be described in detail below with reference to the attached drawings, but the invention can be implemented in many different ways as defined and covered by the claims:

as shown in fig. 1-2, the utility model provides a novel integral type urea filter, including casing 1, filter core 2, be equipped with the filtration cavity in casing 1, filter core 2 establishes in the filtration cavity and separates the filtration cavity for the feed liquor chamber 8 that is located outside filter core 2 and the play liquid chamber 9 that is located filter core 2 of mutual isolation, is equipped with the double-deck hole between the inner wall of filter core 2 and casing 1 and freezes the component, and casing 1 adopts plastic materials to make.

After entering the liquid inlet cavity 8, the urea solution is filtered by the filter element 2, then is gathered in the liquid outlet cavity 9 and flows out, and the double-layer anti-freezing element can play a freeze-proof role at low temperature.

The double-layer anti-freezing element comprises a buffer pressure-resistant sleeve 4 and a lining 5, wherein the buffer pressure-resistant sleeve 4 is made of PU material, and the buffer pressure-resistant sleeve 4 and the inner wall of the shell 1 are integrally formed, so that the structure is simple and reliable, and the cost is low. Buffering withstand voltage cover 4 adopts the PU material to make, and bush 5 adopts rubber materials to make, and buffering withstand voltage cover 4 is hugged closely to bush 5, and bush 5 and buffering withstand voltage cover 4 all have the effect of buffering, can avoid urea solution to freeze the inflation at low temperature and cause the damage to casing 1.

The embedding of the bottom center department of casing 1 installs breather valve 6, and breather valve 6 adopts plastic materials to make, adopts O type circle 7 to seal between the bottom of breather valve 6 and casing 1, and breather valve 6 can discharge because of urea solution when freezing at low temperature, and whole double-deck deicing component is by the air that extrudes, and when whole double-deck deicing component all kick-backed simultaneously, can follow the intake air in breather valve 6 in order to reach pressure balance.

The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, if the method and the technical solution of the present invention are adopted, the present invention can be directly applied to other occasions without substantial improvement, and the present invention is within the protection scope of the present invention.
