Description

Technical Field

[0001] This utility model relates to the field of equipment for detecting insoluble matter in water, and more particularly to an automatic tester for the content of insoluble matter in water. Background Technology

[0002] The detection method for insoluble matter in water typically involves placing a dried sample in a beaker, adding tertiary water, and heating the beaker using an electric furnace or constant temperature water bath while stirring the sample with a glass rod. The heated solution is then slowly poured into a glass frit crucible of known dry weight for vacuum filtration. The beaker and residue are then washed three times with tertiary water at the same temperature, with vacuum filtration used each time. Finally, the glass frit crucible and residue are dried, cooled, and weighed. The content of insoluble matter in water can then be calculated.

[0003] In the aforementioned testing process, the electric furnace heats up from the bottom of the furnace body, while the constant temperature water bath heats up from the water around the beaker. Therefore, the constant temperature water bath heats the beaker more evenly, making it the commonly used heating device. However, the constant temperature water bath heating method also has the following drawbacks: 1. The bottom of the beaker is in direct contact with the water bath, but the bottom of the beaker still heats up relatively quickly; 2. When stirring the beaker with a glass rod, the glass rod may hit the inner wall of the beaker, causing the beaker to shake and become unstable. 3. Because there is a lot of water in the water bath, the liquid level in the water bath is usually above the middle of the outer side of the beaker (otherwise the heating effect of the water bath will be poor). Therefore, when the beaker is clamped and removed by clamping tool, the clamping position is usually located above the outer side of the beaker. This clamping method is not conducive to stability when slightly tilted. Utility Model Content

[0004] The purpose of this invention is to provide an automatic tester for the content of insoluble matter in water that improves the convenience of the detection process and ensures the stability of the cup containing the analyte during water bath heating and stirring.

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic water insoluble content tester, including a support for mounting in a constant temperature water bath, and a plurality of positioning rods spaced apart along the circumference of the support. The positioning rods are rotatably engaged with the support, and the rotatable connection between the positioning rods and the support has an elastic element, so that when the cup is placed on the support, the plurality of positioning rods abut against the outer circumference of the cup for limiting.

[0006] Furthermore, the bracket is provided with several support rings around its circumference, and there is a gap between adjacent support rings.

[0007] Furthermore, the end of the positioning rod has an anti-slip pad so that when the positioning rod abuts against the outer periphery of the cup, the anti-slip pad contacts the outer wall of the cup.

[0008] Furthermore, it also includes a base, which is provided with a number of top rods spaced apart along the circumference. The top rods are arranged in a one-to-one correspondence with the positioning rods, and a through groove is opened on the side of the rotational connection between the bracket and the positioning rod, so that when the bracket is placed on the upper side of the base, the top rod passes through the through groove and pushes the inner side of the positioning rod.

[0009] Furthermore, the outermost support ring has several circumferential grooves, and pull rods are detachably connected to the grooves. Several pull rods are connected to the material picking ring, and the side of the material picking ring has clearance space so that when the pull rods are connected to the grooves, the material picking ring can lift the support.

[0010] Furthermore, the end of the pull rod has a hook, and the hook matches the annular groove.

[0011] Furthermore, the material-taking ring has a first handle on the side away from the bracket, and a second handle is located at one of the pull rods, with the second handle being positioned opposite to the clearance space.

[0012] The beneficial effects of this utility model are as follows: When placing a beaker in a constant temperature water bath, the beaker is first placed on the support, causing several positioning rods to rotate and spring back. These positioning rods then circumferentially abut and clamp the outer wall of the beaker to ensure its stability relative to the support. At this point, the support and the beaker can be placed together in the water bath. When the water bath heats the beaker and a glass rod is used to stir it, the circumferential clamping of the positioning rods and the bottom stabilizing effect of the support prevent the beaker from shaking significantly even when it is stirred or bumped by the glass rod, thus preventing it from tipping over. Furthermore, the rotation and springback of the positioning rods are controlled by elastic elements, allowing beakers of different sizes to be held in place by the positioning rods. This ensures that the support can be used to fix beakers of different sizes to meet the needs of most testing experiments. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0019] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0020] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0021] like Figures 1-4 The present invention provides an automatic tester for the content of insoluble matter in water, including a support 1 for mounting in a constant temperature water bath and a plurality of positioning rods 2 spaced apart along the circumference of the support 1. The positioning rods 2 are rotatably engaged with the support 1, and the rotatable connection between the positioning rods 2 and the support 1 has an elastic element, so that when the cup is placed on the support 1, the plurality of positioning rods 2 abut against the outer circumference of the cup for limiting.

[0022] When placing a beaker in a constant-temperature water bath, first place the beaker on the support, causing several positioning rods to rotate and spring back. These rods then circumferentially clamp the beaker's outer wall to ensure its stability relative to the support. The support and beaker can then be placed together in the water bath. As the water bath heats the beaker and a glass rod stirs it, the circumferential clamping of the positioning rods and the stabilizing effect of the support's bottom prevent significant shaking even when the beaker is stirred or bumped by the glass rod, thus preventing it from tipping over. Furthermore, the rotation and springback mechanism of the positioning rods is controlled by elastic elements, allowing beakers of different sizes to be clamped and held in place. This ensures the support can adaptably fix beakers of different sizes to meet the needs of most testing experiments.

[0023] The elastic element can be a torsion spring structure.

[0024] Preferably, the bracket 1 is provided with a plurality of support rings 3 circumferentially, and there is a gap between two adjacent support rings 3.

[0025] Specifically, the support rings stabilize the support in the circumference, thereby improving the stability of the beaker when it is placed on the support. At the same time, because there are gaps between adjacent support rings, water still exists in the gaps when the beaker is placed on the support for water bath heating. This allows the outer wall and bottom of the beaker to be heated by water as a medium, without the beaker directly contacting the pot body.

[0026] Preferably, the end of the positioning rod 2 has an anti-slip pad 4, so that when the positioning rod 2 abuts against the outer periphery of the cup, the anti-slip pad 4 contacts the outer wall of the cup.

[0027] Specifically, after the positioning rod springs back and clamps the outer circumference of the beaker, the friction between the positioning rod and the outer wall of the beaker is increased by the anti-slip pad, thereby ensuring the stable clamping of the beaker by the positioning rod. Furthermore, when the solution is slowly poured into the beaker, the positioning rod can be stably connected to the outer circumference of the beaker.

[0028] The anti-slip mat can be made of rubber.

[0029] Preferably, the system also includes a base 5, which has a plurality of push rods 6 spaced apart along the circumference. The push rods 6 are arranged in a one-to-one correspondence with the positioning rods 2, and a through groove 7 is provided on the side of the rotatable connection between the bracket 1 and the positioning rod 2, so that when the bracket 1 is placed on the upper side of the base 5, the push rods 6 pass through the through groove 7 to push the inner side of the positioning rod 2.

[0030] Specifically, when the beaker needs to be placed on the support, the positioning rods will initially retract inward due to the action of the torsion spring. To avoid the positioning rods obstructing the beaker, the support is first placed on the upper side of the base, so that the top rod and the positioning rod correspond one-to-one. At this time, press the support to move it towards the base, so that the top rod pushes the inner side of the positioning rod, thereby causing several positioning rods to unfold outward simultaneously. At this time, the beaker can be placed on the support. When the support is detached from the base, several positioning rods will automatically spring back and clamp under the action of the torsion spring.

[0031] Meanwhile, due to the design of the through groove, when the push rod pushes the positioning rod, the push rod will be limited by the through groove, preventing the push rod from leaving the pushing position of the positioning rod, thereby avoiding the situation where the positioning rod is difficult to unfold.

[0032] Preferably, the outermost support ring 3 has several annular grooves 8 along the circumference, and a pull rod 9 is detachably connected to the annular groove 8. Several pull rods 9 are connected to the material picking ring 10, and the side of the material picking ring 10 has a clearance space 11 so that when the pull rod 9 is connected to the annular groove 8, the material picking ring 10 can lift the bracket 1.

[0033] Specifically, when it is necessary to remove the beaker from the water bath, the pull rod is temporarily connected to the ring groove, allowing the material-retrieving ring to directly pull the support away from the water bath, thus facilitating the removal of the beaker. Furthermore, due to the clearance space, after the beaker is removed, it is only necessary to tilt it using the material-retrieving ring and the pull rod, causing the support to tilt the beaker simultaneously. This allows for easy control of the liquid in the beaker to slowly pour into the clearance space, preventing burns or splashing due to unstable beaker control.

[0034] Preferably, the end of the pull rod 9 has a hook 12, and the hook 12 matches the annular groove 8.

[0035] Specifically, when connecting the pull rod to the ring groove, it is fastened to the ring groove by a hook, so that the pull rod can be easily connected to the support ring position, thereby ensuring the stability of the material lifting ring when lifting the bracket.

[0036] In one embodiment of this solution, the hook is configured in a C-shape. When it is necessary to disassemble the pull rod, the material picking ring is pressed down first, and the pull rod is pushed outward at the same time, so that the pull rod can be quickly disengaged from the ring groove position, so as to facilitate the quick separation of the material picking ring from the bracket.

[0037] Preferably, the material handling ring 10 has a first handle 13 on the side away from the bracket 1, and a second handle 14 is provided at a pull rod 9, and the second handle 14 is arranged opposite to the clearance space 11.

[0038] Specifically, when controlling the pouring of liquid from the beaker using the feeding ring, the operator can simultaneously pull the first and second handles to tilt the support, thus ensuring stability during the slow pouring process. The relative arrangement of the second handle and the clearance space allows the liquid in the beaker to be poured into the clearance space when the second handle is raised, preventing liquid from contaminating the lever or other parts.

[0039] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
