Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for collecting a sample liquid from a liquid containing a large amount of residue. Generally, in a liquid analysis test, the presence of a residue in the liquid causes a measurement error and also becomes a factor that obstructs the analysis operation such as clogging of the liquid feeding pipe. The present invention relates to a sampling device capable of collecting a clear sample liquid from which a residue is removed from a liquid containing a large amount of the residue such as a metal smelting solution.

[0002]

[Prior art and its problems]

 A sedimentation type storage tank has been conventionally used to remove the residue from the residue-containing liquid. The settling type storage tank is a type in which the inside of the tank is divided into a plurality of settling tanks and the residue-containing liquid is sequentially poured into each of the settling tanks by overflow to precipitate the residue. Sediments with heavy specific gravity can be removed considerably by this settling tank. However, sediments with a low specific gravity take longer to settle and the removal effect is poor. Instead of such a sedimentation type device, the residue is filtered and separated to be removed. However, if the amount of the residue is large, the load of the filtering material is large and the practicality is poor. It is an object of the present invention to provide a liquid sampling device that solves such conventional problems.

[0003]

[Means for solving the problem]

 The present invention combines a notch part for removing a residue having a relatively large specific gravity from a residue-containing liquid and a filter part for removing a residue having a light specific gravity, and the liquid passing through the notch is directed upward from the bottom of the container. By passing through the inside of the filter part, these residues are effectively separated according to the difference in specific gravity, and the filter material of the sampling tube is permeated to remove the minute residues, thereby forming a sample liquid. It is designed to collect the optimum liquid.

[0004]

According to the present invention, according to the present invention, a liquid receiving part for receiving a liquid containing a residue, a notch part on a bottom of a container for depositing a residue in a liquid introduced from the liquid receiving part, and the notch part A filter part through which the liquid passes and a sampling pipe for collecting the liquid that has passed through the filter part are provided, and the peripheral wall of the sampling pipe having the liquid passage hole is covered with a filter material through which the liquid penetrates. There is provided a sampling liquid sampling device, characterized in that a capillary tube for guiding the liquid that has penetrated into the inside thereof is provided to the outside. In a preferred embodiment, the notch portion is provided below the liquid receiving portion and the filter portion, and the collecting device is such that the residue-containing liquid flows from the lower portion to the upper portion of the filter portion. Provided.

[Specific disclosure of device]

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 is a schematic cross-sectional view of a sampling device according to the present invention, and FIG. 2 is a schematic cross-sectional view of a sampling tube thereof. In the illustrated sampling device, the inside of the container 10 is divided by the partition walls 31 to 34 into a liquid receiving portion 11 that receives the liquid containing the residue, filter portions 12, 13, 14 through which the liquid passes, and the liquid. It is divided into a liquid collecting section 15 for storing and collecting. A liquid supply port 16 is provided above the liquid receiving unit 11 and above the upper surface of the filter unit 11. Below the partition wall 31 partitioning the liquid receiving part 11 and the filter part 12 and the partition wall 33 partitioning the filter part 13 and the filter part 14, notch parts 21 and 22 for depositing the residue in the liquid are provided at the bottom of the container. And a notch portion 21 and 22 and a lower end of the partition walls 31 and 33, respectively. On the other hand, the lower ends of the partition wall 32 partitioning the filter parts 12 and 13 and the partition wall 34 partitioning the filter part 14 and the liquid collection part 15 reach the bottom surface of the container, and block the flow of liquid. The notch portions 21 and 22 have a V-shaped bottom portion formed by a bottom surface which is inclined downward inward, and an outlet port 23 provided with a valve is provided at the lower end thereof. Each of the filter parts 12 to 14 is filled with a filter material that collects the residue in the liquid. Since the residue in the liquid is filtered in order from the one having the larger diameter as it passes through each filter portion, it is preferable to use the filter material of each portion 12 to 14 having the smaller pore diameter in order. Further, the height of each filter material may be set to be gradually lower toward the liquid collecting section 15 so that the liquid can easily flow. The central filter portion 13 may be used as a liquid passage in a void portion without a filter material.

A liquid collecting pipe 40 is horizontally provided near the bottom surface of the liquid collecting section 15. The liquid collection tube 40 is formed by a cylindrical tube, and the tip thereof is sealed by a stopper 41. Further, a large number of liquid passage holes 45 are formed on the peripheral surface, and the entire peripheral surface including the liquid passage holes 45 is entirely covered with a filter material 42 into which liquid permeates. As the filter material 42, a filter material having a smaller pore size than that of the filter portion is used, and as an example, glass wool or the like is used. A weir 43 for accumulating liquid is erected on the bottom surface of the liquid sampling tube 40, and a thin tube 44 that opens below the liquid level height extends to the outside. The rear end of the liquid collection pipe 40 is a drainage port and is connected to the drainage pipe.

The residue-containing liquid supplied from the liquid supply port 16 to the liquid receiving portion 11 flows into the notch portion 21 located below the liquid receiving portion 11 and the filter portion 12, and is contained in the liquid here. Sediments with a large specific gravity are deposited. The residue-containing liquid that has passed through the notch portion 21 flows through the inside of the filter portion 12 from below to above, overflows from above the filter portion 12, flows into the adjacent filter portion 13, and passes through the filter portion 13. Then, it flows into the notch portion 22 below it. While passing through the filter portions 12 and 13, the residue in the liquid is filtered out from the liquid by the filter material, and the relatively fine residue passing through the filter portions 12 and 13 is deposited on the notch portion 22. The residue deposited on the notches 21 and 22 is appropriately discharged to the outside from the outlet 23. The liquid that has passed through the notch portion 22 flows inside the filter portion 14 from the lower side to the upper side, and while passing through the filter portion 14, the fine residue that remains in the liquid is filtered out from the liquid. The liquid that has passed through the filter portion 14 overflows from above the filter portion 14 and flows into the adjacent liquid collection portion 15. Most of the residue of the liquid that has flowed into the liquid collecting portion 15 is removed by the notch portions 21 and 22 and the filter portions 12 to 14, and the liquid that has been significantly purified compared to the liquid in the liquid receiving portion 11. Becomes The liquid permeates the filter material 42 of the liquid collection tube 40 and accumulates therein. This liquid is a clear liquid that does not contain any residue, because the fine residue that remains slightly in the liquid collection unit 15 is removed by the filter material 42, and this liquid is collected outside as a sample solution through the thin tube 44. . Excess liquid is discharged to the outside through the drain port.
