Description

  The present invention relates to a sampler capable of collecting a sample at an arbitrary part of a packing housed in a container, and more particularly to a sampler suitable for collecting a sample at an arbitrary part of a resin tower of an ion exchange resin.

  Conventionally, in a pure water production apparatus that produces pure water with an extremely low impurity concentration, one or two or more different ion exchange resin particles (particle size of about 0.3 to 1.2 mm) are used to remove ions in the water. A single-bed type, mixed-bed type, etc. ion-exchange resin tower packed with is widely used.

  Since the ion exchange capacity of the ion exchange resin tower is lost over time by deionizing the water to be treated, it is necessary to appropriately evaluate the ion exchange performance of the resin particles. Until now, in order to evaluate the performance of resin particles, sampling has been carried out by providing a sampling tube for extracting resin particles in the resin tower and a sampling hole for performing sampling in the resin tower in advance. .

  Providing the sampling tube and the sampling hole in the resin tower in advance fixes the sampling position in the resin tower. Since actual ion exchange differs depending on the amount of water flow, it was necessary to prepare many sampling tubes and holes in order to accurately check the degree of ion exchange progress. However, it is not desirable to provide many sampling tubes and holes not only to increase the production cost but also to stabilize the flow in the resin tower.

  In view of the above problems, the present invention can collect a resin at an arbitrary height from a resin replacement working port that is usually prepared in the upper part of a container for storing a sample such as a resin tower. The purpose is to provide a simple sampler.

  In order to solve the above-mentioned problems, the present invention is a sampler capable of collecting a sample at an arbitrary part of a filling contained in a container, and has a rotating shaft having a pointed portion and the pointed portion as a starting point.

Provided is a sampler in which at least a part of the spiral blade is exposed between the portions (Invention 1).

  According to the above invention (Invention 1), the sample can be sequentially taken into the space surrounded by the spiral blade and the inner wall of the outer cylinder from the exposed portion of the spiral blade starting from the tip, and the sampler is pulled out in this state. Thus, the sample held in the space can be taken out. Further, it is possible to collect a sample at an arbitrary portion of the filling material of the container at the site where the container is installed without stopping the operation of the apparatus in which the container is incorporated for a long time or during the operation of the apparatus. Furthermore, there is an advantage that once the sampler is pulled out, the flow of the fluid to be processed in the container is not disturbed.

  In the above invention 1, it is preferable that at least one of the rotating shaft, the spiral blade, and the inner wall of the outer cylinder is provided with a surface property that causes friction with the sample (invention 2). According to the above invention (Invention 2), when the sampler is rotated, there is no slip in the rotation direction, and the sample is reliably taken into the space surrounded by the spiral blade and the inner wall of the outer cylinder through the exposed portion of the spiral blade. It can be sent to the opposite side of the tip of the tube.

  In the first and second aspects of the invention, it is preferable that a structure for extending the axial length of the rotary shaft is further provided at the end of the rotary shaft opposite to the pointed portion (Invention 3). According to the said invention (invention 3), the axial length of a rotating shaft can be changed flexibly according to the height and depth of the tower which should collect a sample.

  In the first to third aspects of the present invention, it is preferable that a connecting member for connecting to a driving member for rotationally driving the rotating shaft is further provided at an end portion of the rotating shaft opposite to the pointed end portion. 4). According to the above invention (Invention 4), the rotational driving force of the driving member is reliably transmitted to the sampler, and efficient sampling can be performed.

  In the first to fourth aspects of the present invention, it is preferable that the outer peripheral surface of the rotating shaft is provided with a depth scale indicating the sampling depth or the reaching depth of the tip (invention 5). According to the said invention (invention 5), the sample of the desired depth can be extract | collected.

  In the first to fifth aspects of the present invention, it is preferable that the outer cylinder has a shape in which the opening end on the side of the pointed end is sharp (invention 6). According to the above invention (Invention 6), the outer cylinder itself can smoothly enter the packing as the rotary shaft rotates, and the sample is obtained while cooperating with the entry of the tip portion into the sample. Can be smoothly carried out.

  In the said invention 1-6, it is preferable that the packing accommodated in the said container is the ion exchange resin accommodated in the resin tower (invention 7). According to the above invention (Invention 7), if the sampler is pulled out, the packing is hardly damaged and the flow of the water to be treated in the resin tower is not disturbed when the apparatus is in operation. It can be said that the configuration of the samplers 1 to 6 is particularly advantageous.

  According to the sampler of the present invention, it is possible to collect a sample at an arbitrary part of the filling while the filling is contained in the container. Further, once the sampler is pulled out, there is an advantage that the flow of the fluid to be processed in the container is not disturbed. Furthermore, the sample can be collected without stopping the operation of the apparatus incorporating the container for a long time at the installation site of the container.
