Abstract
The utility model discloses a be suitable for magnetic stirrers's second grade agitating unit, including the base, make progress perpendicularly and fix the pivot at base center, rotate the cover through the axle sleeve in the pivot and be equipped with the magnet tray, the cavity has been seted up to the upper surface of magnet tray, be provided with high temperature resistant magnet in the cavity, the upper shed of cavity is provided with sealed lid and fixed through the fastener. The utility model has the advantages that the high temperature resistant magnet is sealed and wrapped inside the concave cavity, thereby reducing the corrosion of the medium to the high temperature resistant magnet; the vertical lines arranged on the lower surface (stirring surface) of the magnet tray and the grooves arranged along the radial direction increase the contact area and the friction force with the medium, more media can be driven to move under the same condition, and the consistency of the internal temperature of the stirring container is greatly improved.
Description
Technical Field
The utility model relates to a magnetic stirrers especially relates to be suitable for magnetic stirrers's second grade agitating unit.
Background
The second-stage stirring device is a common device for realizing constant temperature precision requirement in the work of the magnetic stirrer. Present second grade agitating unit is mostly the stirring sub-form, though small, but the not enough of existence is: when a medium with high stirring viscosity and a stirring container have large volume, the temperature of the medium cannot be quickly kept constant, and the temperature difference between temperature areas is large, so that the temperature conditions required by experiments cannot be well met.
Disclosure of Invention
An object of the utility model is to provide a stirring is efficient, job condition is stable be suitable for magnetic stirrers's second grade agitating unit.
In order to achieve the above purpose, the utility model adopts the following technical proposal:
be suitable for magnetic stirrers's second grade agitating unit, including the base, upwards fix perpendicularly the pivot at base center, rotate the cover through the axle sleeve in the pivot and be equipped with the magnet tray, the cavity has been seted up to the upper surface of magnet tray, be provided with high temperature resistant magnet in the cavity, the upper shed of cavity is provided with sealed lid and is fixed through the fastener.
The cavities arranged on the upper surface of the magnet tray are symmetrical to the two cavities arranged on the rotating shaft, and the two cavities are respectively provided with one high-temperature resistant magnet.
The lower surface of the magnet tray is provided with vertical grains and grooves which are arranged along the radial direction.
The fastener is a cap nut.
The utility model has the advantages that the high temperature resistant magnet is sealed and wrapped inside the concave cavity, thereby reducing the corrosion of the medium to the high temperature resistant magnet; the vertical lines arranged on the lower surface (stirring surface) of the magnet tray and the grooves arranged along the radial direction increase the contact area and the friction force with the medium, more media can be driven to move under the same condition, and the consistency of the internal temperature of the stirring container is greatly improved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic top view of the structure of fig. 1.
Fig. 3 is a schematic view of the structure of the present invention in use state of the magnetic stirrer.
Detailed Description
The following describes embodiments of the present invention in detail with reference to the drawings, which are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are provided, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1 and 2, be suitable for magnetic stirrers's second grade agitating unit, including disc structure's base 1, perpendicular upwards fixes in pivot 2 at base 1 center, and it is equipped with magnet tray 4 to rotate the cover through axle sleeve 3 in the pivot 2, and magnet tray 4 lower surface has seted up the erecting line and has radially seted up the recess, and two cavities have been seted up in magnet tray 4's upper surface symmetry in pivot 2, are provided with a high temperature resistant magnetism 5.1 in two cavities respectively, 5.2, and the upper shed department of two cavities is provided with sealed lid 6.1 respectively, 6.2, then it is fixed through the lid shape nut 7 with 4 threaded connection of magnet tray.
The assembly sequence of the magnet tray 4 is as follows: two high temperature resistant magnet 5.1, 5.2 pack into two concave cavities of magnet tray 4 respectively earlier, then seal through two sealed lids 6.1, 6.2, and then be in the same place lid shape nut 7 and magnet tray 4 screw thread soon, and 3 interference fit suits of axle sleeve are in the center of magnet tray 4 at last.
In actual manufacturing, the magnet tray 4, the sealing covers 6.1 and 6.2 and the cap-shaped nut 7 are made of polytetrafluoroethylene materials; the base 1 and the rotating shaft 2 are made of stainless steel; the shaft sleeve 3 is made of high-temperature-resistant and wear-resistant engineering plastics.
The working process of the utility model is as follows:
as shown in figure 3, when in use, the utility model is placed inside a bath 9 of a magnetic stirrer 8, a magnet 10 inside the magnetic stirrer 8 drives a magnet tray 4 to rotate, and the rotation of the magnet tray 4 drives a medium in the bath 9 to move, so that the temperature of the medium is uniform and stable.
The utility model discloses a second grade agitating unit has realized the great medium of viscosity and the great bath of volume to the even unanimous requirement of temperature, the occasion that has special temperature test requirement in the specially adapted laboratory.
