Abstract
Description
Technical Field
[0001] The utility model relates to the field of water quality monitoring, in particular to a defoaming flow path based on a honeycomb structure. Background Art
[0002] The water quality parameters are measured by incidenting a beam of light into the water sample, and then receiving the outgoing light at a specific angle through the optical receiver, so as to calculate the water quality parameters. In the process of online water quality monitoring, if the collected water sample contains bubbles, it will affect the accuracy of the measured value. In the prior art, there are mainly two technical solutions for eliminating bubbles in the water flow path: one is to eliminate bubbles under pressure, and the other is a large flow path grid type bubble elimination structure. To eliminate bubbles under pressure, the entire system must be closed and the pressure must be increased so that bubbles cannot be generated, but this solution has three disadvantages: 1. There are requirements for the water inlet pressure. If the water inlet pressure is too small, the expected effect cannot be achieved; 2. The essence of pressurization lies in the regulation of water outlet. If a large pressure is required, the outlet needs to be adjusted down, which easily causes the outlet to be blocked; 3. The cost is high. The large flow path grid type bubble elimination structure can achieve the effect of eliminating bubbles, but it also has shortcomings: 1. The large flow path causes the whole machine to be large, which is not conducive to integration; 2. The mold opening cost of the large flow path is expensive; 3. The large flow path makes the structural parts more complicated. Summary of the invention

[0030] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:
[0031] Embodiment 1
[0032] See also Figures 1 to 6A defoaming flow path 40 based on a honeycomb structure comprises a fluid channel 1 and a defoamer 2, wherein the defoamer 2 is arranged on the fluid channel 1 and the fluid in the fluid channel 1 flows in from the water inlet end face 21 of the defoamer 2 and flows out from the water outlet end face 22 of the defoamer 2. A plurality of columnar through holes 23 for fluid to pass through are arranged in the defoamer 2 at intervals, wherein the columnar through hole 23 comprises two openings and a hole wall 231 located between the two openings, and the two openings are respectively arranged on the water inlet end face 21 and the water outlet end face 22 of the defoamer 2. The columnar through holes 23 are not connected to each other, forming a honeycomb structure. The cross section of the columnar through hole 23 is circular or polygonal. For example, the columnar through hole 23 can be a cylinder or a hexagonal cylinder. Regardless of the shape of the through hole, the purpose is to maximize the contact area between the fluid and the hole wall 231. Since bubbles in the fluid are easily attached to the side wall of the container, when the fluid passes through the defoamer 2, the bubbles will adhere to the hole wall 231. The present application adopts a defoamer 2 with a honeycomb structure, which greatly increases the area of the hole wall 231, thereby increasing the contact area between the fluid and the hole wall 231, improving the bubble wall attachment ability of the defoamer 2, and greatly reducing the amount of bubbles in the fluid.
[0033] The arrows in the drawings in the present specification all indicate the flow direction of the fluid.
[0034] The fluid channel 1 has various forms, three of which are listed below.
[0035] Implementation method 1: Please refer to Figure 1 , the fluid in the fluid channel 1 flows in the horizontal direction, the fluid flows in from the water inlet end face 21 of the defoamer 2, and flows out from the water outlet end face 22 of the defoamer 2, and the bubbles in the fluid adhere to the hole wall 231 of the defoamer 2. In this embodiment, multiple defoamers 2 can be arranged at intervals along the flow direction to completely eliminate the bubbles in the fluid. At the same time, multiple defoamers 2 can be arranged side by side in a continuous manner in the flow channel width direction of the fluid channel 1 to ensure that the fluid flows to the outlet after passing through the defoamer 2. Thereby, the amount of bubbles in the fluid is greatly reduced.
[0036] Implementation Method 2: Please refer to Figures 2 to 3 , the fluid in the fluid channel 1 flows in the vertical direction, the upper end face of the defoamer 2 is the water inlet end face 21, and the lower end face is the water outlet end face 22. The fluid flows downward under the action of gravity. When flowing through the defoamer 2, the bubbles in the fluid adhere to the hole wall 231, thereby reducing the amount of bubbles in the fluid. The defoamers 2 can be arranged in multiple longitudinal intervals and in the flow channel width direction of the fluid channel 1, multiple defoamers 2 can be arranged side by side and continuously. Their functions are the same as those in the first embodiment and will not be repeated.
[0037] Embodiment 3: When there are many bubbles in the fluid and multiple defoamers 2 are needed, the defoamers 2 can be simply arranged side by side, or multiple defoamers 2 can be arranged at intervals along the fluid movement direction to improve the bubble elimination capability. Figure 4 and Figure 5 This embodiment provides a preferred method for continuously arranging a plurality of defoamers 2. A plurality of partitions 3 for changing the flow direction of the water body are arranged at intervals on the fluid channel 1. The partitions 3 include an upper partition 31 and a lower partition 32. The upper partitions 31 and the lower partitions 32 are alternately distributed in the horizontal direction and staggered in the vertical direction. The defoamers 2 are arranged in the space surrounded by the adjacent upper partitions 31 and the lower partitions 32 and the side wall of the fluid channel 1. A tortuous flow path is formed by staggered upper partitions 31 and lower partitions 32, and a defoamer 2 is arranged in each section of the flow path, so that a plurality of defoamers 2 are arranged on a shorter fluid channel 1 to fully absorb bubbles in the fluid.
[0038] The utility model provides a defoaming flow path 40 based on a honeycomb structure. The defoamer 2 used in the utility model is small in size, and a small-volume defoaming flow path 40 can be made for use in a variety of products with flow paths. It is also convenient for customers to integrate it into the existing fluid channel 1. The utility model can also be used in situations where the fluid contains large particles, and no particles will block the water outlet 501. The defoamer 2 of the utility model has a simple structure and low cost, and the defoaming flow path 40 has a low cost, a good bubble elimination effect, and makes the measurement value in the photoelectric detection more stable.
[0039] Based on the same inventive concept, the present application also provides a measuring cell, in which a defoaming flow path 40 provided with a defoamer 2 is applied to the measuring cell, as shown in Example 2 for details.
