JPH0680157U - Initial liquid collector - Google Patents

Abstract

(57) [Summary] [Purpose] The purpose is to reliably collect an initial liquid as a test sample using a simple instrument. [Structure] An initial liquid collecting device in which a float having a flexible sheet-shaped magnet attached thereto rises or moves due to inflowing liquid and is adsorbed as a lid in a sampling hole.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sample liquid sampler for inspection.

[0002]

[Prior art]

 For example, it is well known that in tap water testing, the water that is first collected early in the morning by opening the tap is the most suitable test sample. Even in the case of acid rain inspection, the rain that begins to fall has a higher acidity and is suitable as a pollution sample. However, accurate sampling of only the initial liquid required a large-scale device.

[0003]

[Problems to be solved by the device]

 This method ensures that only the initial liquid is collected by using an extremely simple device.

[0004]

[Means for Solving the Problems]

 As a means of that. The structure is such that the lid is automatically closed when the liquid entering from the sampling hole reaches a certain amount.

[0005]

[Action]

 The operation of the present invention will be described with reference to the drawings. A stopper 2 made of a material such as rubber is press-fitted into the bottom of the main cylinder 1. Inside the cylinder, a magnet 4 made of a flexible sheet-like rubber, plastic, or the like is attached to the upper surface, and a float 4 that is raised or moved by the inflowing liquid is placed. Then, a sampling cylinder 5 is attached to the upper part of the main cylinder 1. The upper part of the sampling cylinder 5 serves as a sampling port 6, and the flange 7 in the middle portion positions the fitting end surface of the main cylinder 1. An iron-based plate 9 having a sampling hole 8 is provided below the sampling cylinder 5. When this is used as an assembly 10 and liquid is made to flow in through the sampling port 6, the float 4 rises or moves, and the magnet 3 is attracted to the iron-based plate 9 of the sampling tube 5 as the lid of the sampling hole 8 to thereby The liquid flow into the cylinder 1 is stopped, and only the initial liquid is stored in the main cylinder 1 as a sample.

[0006]

Embodiment 1 As shown in FIG. 3, by using a funnel cylinder 12 having a collar 7 of the sampling cylinder 5 and a fitting end surface position fitting of the upper part thereof, the inner cylinder 11 is used, for example, when tap water is initially used. The sample collection can be facilitated. Reference numeral 13 is a filter material made of non-woven fabric or the like provided depending on the situation.

[0007]

Second Embodiment As shown in FIG. 4, a plurality of funnel cylinders 12 are installed at a distance from the assembly 10 via pipes 14, so that even a small amount of acid rain, for example, can be used in an appropriate, appropriate amount, and in a wide range. Can be collected.

[0008]

Third Embodiment FIG. 5 and FIG. 6 show a third embodiment of the present invention for collecting a submerged sample at a certain depth, for example. FIG. 5 shows a state before being put in the liquid, and FIG. 6 shows a state in which the liquid to be the sample flows in the liquid. In the figure, 3 is a magnet, 4 is a float, 8 is a sampling hole, and 9 is an iron-based plate, which are basic conceptual parts of the present invention. In FIG. 5, a sampling port 16 is provided at the bottom of the container cylinder 15, and the atmosphere 20 is sealed by a float 4 which is integrated with a sliding stopper 19 by a connecting rod 18 via a packing 17. When this is submerged in liquid, when the liquid pressure at that depth exceeds the pressure of the atmosphere 20 sealed in the container cylinder 15, the resistance of the sliding stopper 19, the gravity of parts, etc., as shown in FIG. The liquid flows in through the sampling port 16, the float 4 moves so as to be pushed up, and is sucked into the sampling hole 8 as a lid. When the liquid is pulled up from the liquid, the liquid closed and stored by the sliding stopper 19, the iron-based plate 9 and the magnet 3 can be used as the sample of the depth. In addition, 21 shows a tow line.

[0009]

[Effect of device]

 In this plan, when the liquid flowing in from the sampling hole reaches a certain amount, the lid is automatically closed by the action of the magnet, and the closed liquid will not leak due to vibration, displacement, temperature, pressure change, etc. Absent. The structure is simple, inexpensive, but highly contrived, and easy to handle, so it can be expected to spread in many fields.
