Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of solution preparation equipment, and particularly relates to a device for preparing vehicle urea solution. Background Technique
[0002] Vehicle urea is an important raw material for the purification treatment of diesel engine exhaust gas. It acts on the exhaust gas purification device and converts nitrogen oxides in the vehicle exhaust gas into harmless nitrogen and water through chemical reactions, thereby improving the operation and fuel consumption of the vehicle engine and making the vehicle exhaust gas meet the specified emission standards. During its production, in order to achieve the predetermined use performance, a special mixing device is often used to quantitatively prepare the materials.
[0003] Currently, it is found in the actual application of the existing urea solution preparation equipment that the feeding of materials is often limited to a certain area, which leads to the inability of multiple materials to be quickly fused, resulting in the situation of sinking to the bottom, affecting the preparation efficiency and easily forming precipitates to reduce the quality.
[0004] To solve the above problems, a device for preparing vehicle urea solution is proposed in this application. Content of the Utility Model
[0005] The purpose of the utility model is to provide a device for preparing vehicle urea solution, which solves the problems raised in the above background technique.
[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0007] The utility model is a device for preparing vehicle urea solution, including: a preparation tank and a top cover above it; a material spreading pipe for rotating and spreading materials is arranged inside the preparation tank, and a rotating shaft is arranged inside the preparation tank to drive the material spreading pipe to rotate, and the applied materials are stirred by the stirring blades on the outside to promote fusion; an annular material bucket and auxiliary material buckets equally spaced below it are also arranged inside the preparation tank, on the same side of the rotating shaft, for installing the material spreading pipe. A feeding cylinder is arranged on one side of the top cover, and the materials are conveyed to the annular material bucket through the feeding pipe below it, and then conveyed to the auxiliary material buckets through the material conveying pipe below the annular material bucket, so that the materials are fed in different depth areas to ensure the mixing uniformity.
[0008] Further, a sealing cover is arranged at the lower end of the feeding pipe, and it is rotatably installed above the annular material bucket to form a seal.
[0009] Further, guiding slopes for guiding the materials to gather are arranged at the bottoms of the annular material bucket and the auxiliary material buckets.
[0010] Further, positioning holes for the falling of materials are arranged at the lower end of the material spreading pipe.
[0011] Further, a ring frame is provided above the annular material bucket and is connected to a position adjacent to the upper end of the rotating shaft through a pin body mechanism, so that the annular material bucket rotates following the rotating shaft.
[0012] Further, the stirring blades are located below the material spreading pipe and are used to stir the materials spread out for the first time and mix them with other materials.
[0013] Further, the material spreading pipe is an inclined mechanism to promote the flow of materials to the outer ring area of the preparation tank.
[0014] The utility model has the following beneficial effects:
[0015] Through the rotational connection between the sealing cover and the annular material bucket of the utility model, the materials can directly enter the interior of the material spreading pipe, and then, when the rotating shaft rotates, the effect of circumferentially spreading the materials can be achieved. Compared with the existing equipment, it can effectively prevent the input materials from being limited to a certain area, expand the spreading range of the materials to promote the mixing efficiency with other materials, and at the same time prevent the situation of sinking to the bottom, ensuring the production and preparation quality of the urea solution;
[0016] In addition, when the materials enter the annular material bucket, they can also be transferred to the interior of the auxiliary material bucket below through the material conveying pipe, and then the material spreading pipes distributed below are used for feeding operation to expand the contact range between the materials and other materials, achieving the effect of feeding at multiple depths simultaneously, making the materials in different areas mixed evenly to improve the mixing efficiency of the materials and shortening the preparation cycle to improve the production quality.
