Quantitative supply device installation base

Abstract

This article is a quantitative supply instrument installation base on which a plurality of quantitative supply instruments used for dropping an appropriate amount of reagent or the like into a tank are installed. This article is composed of a base on which a tank with an open upper surface is installed, a support column extending vertically upward from the upper surface of the base, and a plurality of mounting tables attached to this support column on which the quantitative supply instruments can be respectively placed. As an example of the use of this article, as shown in [Reference front view showing the usage state] and [Reference plan view showing the usage state], for example, a cylindrical reaction tank with an open upper surface is positioned and installed on the base, and a syringe pump, which is an example of a quantitative supply instrument for dropping a reagent into the reaction tank, is respectively placed on the above-mentioned plurality of mounting tables (four in this example). In this example of use, the base has a rectangular base body on which the reaction tank can be installed, and is composed of support legs extending downward from the four corners of the lower surface of the base body to support the base body. Here, the base body has a downward surrounding frame around the periphery of a rectangular flat plate, and all four support legs use angle materials with an L-shaped cross-section, and mounting brackets for installation are fixed to their lower ends. Further, the support column is provided in an area outside the area where the reaction tank is installed among the areas on the base, and is composed of a long metal rod with a circular outer cross-section, and the lower end of the rod is fixed to the base. In this example, as the fixing structure of the support column, a mode in which fixing parts are provided in advance at the lower part of the support column is used. Specifically, the lower end of the rod is fixed to the approximate center of a rectangular fixing plate, and in order to prevent the rod from falling, the lower periphery of the rod is held by support plates at an angular interval of about 90° on the fixing plate, and a method of fixing the fixing plate on the base is adopted. Furthermore, the mounting table has a mounting table body in which a surrounding frame is formed by rising around the periphery of a substantially rectangular flat plate, and an L-shaped mounting plate is provided at a location facing one side of the lower surface of this mounting table body, and is held by the support column via a holder fixed to the mounting plate. In this example, as the holder, a set collar that can slide along the direction in which the support column extends and can be rotationally adjusted with respect to the rotation direction of the support column is used. This set collar is fixed to the support column by tightening the clamp lever, and the height position and rotational direction position with respect to the support column are adjusted by loosening the clamp lever.In the usage example of this article, the mounting tables are arranged in a staggered pattern along the direction in which the support columns extend when viewed from the front. And a plurality of syringe pumps are placed on each mounting table and are three-dimensionally arranged in the vertical direction of the support columns. Therefore, when viewed from directly above in the vertical direction, the syringe pumps can be placed in a smaller area compared to the mode of arranging the syringe pumps horizontally. For this reason, the occupied space of the syringe pumps around the reaction tank can be reduced. Along with this, it becomes possible to widely secure the working space for the operator around the reaction tank, and it becomes possible to easily perform operations such as the operation of collecting the reaction solution held in the reaction tank in the vicinity of the reaction tank. In the usage example of this article, the syringe pump placed on the mounting table is equipped with a syringe capable of protruding a reagent by an arbitrarily set amount. The reagent discharged from the syringe flows through the inside of a needle or a tube, which is a transport means attached to the tip of the syringe, and is transported and dropped onto the reaction solution contained in the reaction tank. In this article, each syringe pump is respectively arranged on each mounting table, and the tip of the transport means attached to the tip of the syringe is arranged within the upper region of the opening of the reaction tank. For this reason, in this usage example, the transport distance of the reagent from the tip position of the syringe to the dropping position of the reagent can be shortened. In particular, in this example, since the mounting tables arranged in a staggered pattern are arranged at the same position in the vertical direction, in order to prevent the dropping position of the reagent of the syringe pump arranged on the upper side from interfering with the syringe pump arranged on the lower side, the transport distance of the transport means of each syringe pump can be changed, or the installation position of the syringe pump on the mounting table can be changed. Incidentally, in this usage example, although not shown, a stirrer may be installed in the vicinity of the installation location of the reaction tank on the base to stir the reaction solution contained in the reaction tank. Thus, this article has the illustrated form as the basic form, but it is possible to appropriately change the basic form into a form similar to the basic form. For example, the base has a form including a base body and support legs, but within a similar range, it may be changed to a mode of changing the length of the support legs or a mode of directly installing the base body without using the support legs.Also, regarding the fixing structure of the support column to the base, in this article, the support column has a fixing part provided in advance at the lower part of the support column. However, within a similar scope, the support column may be fixed to the base using a fixing part that is a separate part from the support column. Further, in the usage example of this article, the placement tables are illustrated as being arranged in a staggered pattern along the direction in which the support column extends. However, it goes without saying that the placement tables located above and below may be arranged at the same position, or may be arranged with a slightly shifted rotational position. Furthermore, regarding the layout of the plurality of placement tables, it is not limited to a staggered pattern, and of course, it may be arranged in a line along the direction in which the support column extends. Moreover, regarding the holding structure of the placement table with respect to the support column, it is not limited to the illustrated example, and it may further have a mechanism capable of adjusting the horizontal distance between the placement table and the axial center of the support column. By having such a mechanism, the tip position of the syringe pump can be moved to an arbitrary position such as the horizontal center of the reaction tank, and the position where the reagent is dropped can be easily adjusted. Incidentally, in the usage example of this article, a syringe pump is cited as an example of the metering supply device for explanation, but it is not limited to this, and a tube pump, a diaphragm metering pump, etc. may be appropriately selected without any problem.
