Abstract
Description
Technical Field
[0001] This utility model relates to the field of solution impurity detection technology, and in particular to an impurity detection device for automotive urea solution. Background Technology
[0002] Automotive urea is an essential product for heavy-duty diesel vehicles to meet the China IV emission standards. Automotive urea refers to a urea solution with a concentration of 32.5% and ultrapure water as the solvent. The raw materials are special automotive urea raw materials and ultrapure water. In order to ensure the quality of automotive urea solution, it is often necessary to sample and test it.
[0003] Currently, when testing the impurity content inside automotive urea solution, it is usually necessary to open the automotive urea storage container, take a sample separately, and then test it. Since the automotive urea solution is in a static state inside the storage container, impurities are prone to precipitation, leading to inaccurate testing. At the same time, when the automotive urea solution is circulating, it is impossible to detect the impurity content of the automotive urea solution flowing inside the pipeline in a timely manner. When there are many impurities in the solution, it is easy to clog the pipeline. Utility Model Content
[0004] In order to solve the problems of the prior art, this utility model provides an impurity detection device for automotive urea solution.
[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0006] An impurity detection device for automotive urea solution includes a supply pipe, a sealing protective cover fixed to one side of the supply pipe, one side of the sealing protective cover being connected to the supply pipe, a sealing turntable disposed inside the sealing protective cover, a plurality of through holes extending to the bottom being equidistantly opened at the top of the sealing turntable along the circumferential direction, a measuring cylinder disposed inside each of the plurality of through holes, the bottom of each of the plurality of measuring cylinders being open, and one side of the sealing turntable extending into the interior of the supply pipe.
[0007] Optionally, the tops and bottoms of the plurality of graduated cylinders are flush with the tops and bottoms of the sealing turntable.
[0008] Optionally, the bottom of the sealing turntable is located in the middle and rotates into the inside of the groove, and the outer surface of the supply pipe is fixed with docking rings near the top and bottom edges.
[0009] Optionally, an adjusting ring is threaded between the inner walls of the measuring cylinder near the bottom edge, and a support ring is fixed between the inner walls of the adjusting ring.
[0010] Optionally, filter sheets are provided between the tops of the support rings, and pressure rings are threadedly connected between the inner walls of the adjusting rings.
[0011] Optionally, the filter element is located between the bottom of the pressure ring and the top of the support ring, and six slots are provided between the top of the pressure ring and the inner wall of the adjustment ring near the bottom edge.
[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:
[0013] 1. In this utility model, when using this device, the sealing turntable is rotatably connected to the inside of the sealing protective cover, so that one side of the sealing turntable extends into the inside of the supply pipe. At the same time, under the sealing effect of the sealing protective cover, the connection between the sealing turntable and the supply pipe is sealed to prevent leakage. Multiple through holes are opened on the sealing turntable, and a measuring cylinder is placed inside the through holes. Thus, when the sealing turntable is rotated, the measuring cylinder can be rotated into the inside of the supply pipe. When the solution inside the supply pipe fills the measuring cylinder, the measuring cylinder is rotated out and left to stand, so that the solution inside the measuring cylinder is filtered out by the filter plate, leaving impurities on the filter plate. Then, the cleanliness of the solution can be obtained by observing the impurities on the filter plate.
[0014] 2. In this utility model, when installing the filter, first place the filter on the support ring, and then rotate the pressure ring so that the edge of the filter can be pressed tightly against the top of the support ring. The adjusting ring and the measuring cylinder are threaded together to facilitate the adjustment of the volume of the measuring cylinder. Attached Figure Description

Detailed Implementation
[0022] The present invention will now be described in further detail with reference to the accompanying drawings.
[0023] Example 1, such as Figure 1-3 As shown, this utility model provides a technical solution for an impurity detection device for automotive urea solution: it includes a supply pipe 1, a sealing protective cover 3 fixed on one side of the supply pipe 1, one side of the sealing protective cover 3 being interconnected with the supply pipe 1, a sealing turntable 4 being provided inside the sealing protective cover 3, and multiple through holes 5 extending to the bottom being equidistantly opened at the top of the sealing turntable 4 along the circumferential direction, each through hole 5 containing a measuring cylinder 7, the bottom of each measuring cylinder 7 being open, and one side of the sealing turntable 4 extending into the interior of the supply pipe 1.
[0024] The overall effect of Embodiment 1 is that, when using this device, the sealing turntable 4 is rotatably connected to the inside of the sealing protective cover 3, so that one side of the sealing turntable 4 extends into the inside of the supply pipe 1. At the same time, under the sealing effect of the sealing protective cover 3, the connection between the sealing turntable 4 and the supply pipe 1 is sealed to prevent leakage. Multiple through holes 5 are opened on the sealing turntable 4, and a measuring cylinder 7 is placed inside the through holes 5. Thus, when the sealing turntable 4 is rotated, the measuring cylinder 7 can be rotated into the inside of the supply pipe 1. When the solution inside the supply pipe 1 fills the measuring cylinder 7, the measuring cylinder 7 is rotated out and left to stand, so that the solution inside the measuring cylinder 7 is filtered out by the filter plate 10, leaving the impurities on the filter plate 10. Then, the cleanliness of the solution can be obtained by observing the impurities on the filter plate 10.
[0025] Example 2, as Figure 1-3 As shown, the tops and bottoms of multiple measuring cylinders 7 are flush with the tops and bottoms of the sealing turntable 4. The bottom of the sealing turntable 4 is located in the middle and rotates and engages inside the groove 6. The outer surface of the supply pipe 1 is fixed with docking rings 2 near the top and bottom edges. The inner walls of the measuring cylinders 7 are threadedly connected with adjusting rings 8 near the bottom edge. The inner walls of the adjusting rings 8 are fixed with support rings 11. The top of the support rings 11 is provided with filter plates 10. The inner walls of the adjusting rings 8 are threadedly connected with pressure rings 9. The filter plates 10 are located between the bottom of the pressure rings 9 and the top of the support rings 11. Six bayonets 12 are provided between the top of the pressure rings 9 and the inner walls of the adjusting rings 8 near the bottom edge.
[0026] The effect achieved by the entire embodiment 2 is that when installing the filter 10, the filter 10 is first placed on the support ring 11, and then the pressure ring 9 is rotated so that the edge of the filter 10 can be pressed tightly against the top of the support ring 11. The adjusting ring 8 is threadedly connected to the measuring cylinder 7, which facilitates the adjustment of the volume of the measuring cylinder 7.
[0027] Working principle: When using this device, the sealing turntable 4 is rotatably connected to the inside of the sealing protective cover 3, so that one side of the sealing turntable 4 extends into the inside of the supply pipe 1. At the same time, under the sealing effect of the sealing protective cover 3, the connection between the sealing turntable 4 and the supply pipe 1 is sealed to prevent leakage. Multiple through holes 5 are opened on the sealing turntable 4, and a measuring cylinder 7 is placed inside the through holes 5. Thus, when the sealing turntable 4 is rotated, the measuring cylinder 7 can be rotated into the inside of the supply pipe 1. When the solution inside the supply pipe 1 fills the measuring cylinder 7, the measuring cylinder 7 is rotated out and left to stand, so that the solution inside the measuring cylinder 7 is filtered out by the filter plate 10, leaving impurities on the filter plate 10. The cleanliness of the solution can then be determined by observing the impurities on the filter plate 10. When installing the filter plate 10, first place the filter plate 10 on the support ring 11, and then rotate the pressure ring 9 to press the edge of the filter plate 10 tightly against the top of the support ring 11. The adjusting ring 8 is threadedly connected to the measuring cylinder 7 to facilitate the adjustment of the volume of the measuring cylinder 7.
