Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a crucible transfer auxiliary device for a carbon-sulfur instrument. Background Art

[0002] When the carbon-sulfur analyzer detects sulfuric acid, the crucible containing sulfuric acid needs to be pushed into the carbon-sulfur analyzer from the bottom through the crucible base, heated and tested. After the test is completed, the crucible base is lowered, and then the crucible is moved away, and a new crucible is placed to test a new sulfuric acid sample.

[0003] In this process, the crucible after the test is transferred by manually holding the crucible with a crucible tongs and transferring it from the crucible base. Since the carbon-sulfur analyzer heats the crucible and the sulfuric acid contained therein, the temperature of the crucible and the sulfuric acid is very high after the test, which is dangerous. When clamping and transferring the crucible, in order to keep the crucible horizontally stable, the operator needs to operate very carefully, and the transfer operation is not convenient and safe enough. Utility Model Content

[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0042] The carbon and sulfur detector used in our factory requires the crucible containing the sample to be tested to be placed on the top of the crucible base by hand or with crucible tongs. After starting the machine, the crucible base rises and pushes the crucible into the detector for heating and testing. After the test is completed, the crucible base drops, and the crucible needs to be moved away to make room for the next sample to be tested.

[0043] At present, the method of transferring the crucible after the test is to manually hold the crucible with a handheld crucible tongs and transfer it from the crucible base. Since the sample analyzer will heat the crucible and the sample contained therein, the temperature of the crucible and the sample is very high after the test. When clamping and transferring the crucible, the operator needs to operate very carefully, and the transfer operation is not convenient and safe enough.

[0044] To this end, this embodiment provides a crucible transfer auxiliary device for a carbon and sulfur detector, such as Figure 1-3 As shown, the device includes a base 1, a vertical support rod 2, a horizontal support rod 3, and a crucible clamp 4.

[0045] The device base 1 is fixedly installed on the instrument table of the carbon-sulfur detector, and the vertical support rod 2 is rotatably installed on the device base 1; the horizontal support rod 3 is fixedly installed on the top of the vertical support rod, and the installation point is at the midpoint of the horizontal support rod 3, and the crucible clamp 4 is installed on the end of the horizontal rod.

[0046] Before use, the device base 1 is positioned so that the center point trajectory of the crucible clamp 4 passes through the center point of the crucible base A.

[0047] When in use, hold the crucible to be inspected with the crucible clamp 4 on the left, turn the horizontal support rod 3 with the left hand to place the crucible directly above the crucible base A, gently release the crucible clamp 4 and place the crucible on the crucible base A. Then withdraw the horizontal support rod 3 to the initial position.

[0048] After the inspection is completed, grasp the crucible clamp 4 on the right side with your right hand to open it, and at the same time push and rotate the horizontal support rod 3 forward. When it is above the crucible base, relax your hand so that the handle of the crucible clamp 4 clamps the crucible, and then pull the right half of the horizontal support rod 3, withdraw the right half of the horizontal support rod 3, and continue to pull for a distance after resetting, so that the crucible clamp 4 is offset above the instrument table processing and recycling bucket, and then hold the handle of the crucible clamp 4 to open the crucible clamp 4, and the crucible falls into the recycling bucket.

[0049] It can be seen that when using the crucible transfer auxiliary device for the carbon-sulfur detector of this embodiment, there is no need to manually maintain the balance of the crucible when transferring the crucible after detection, which is more convenient and safer.

[0050] When preparing to transfer the crucible after testing, you can also use the crucible clamp on the left to hold the crucible to be tested. When transferring the crucible after testing, you can also place the crucible to be tested on the crucible base A to facilitate the sample delivery and testing of the crucible to be tested.

[0051] The following is a detailed introduction to the structure of each part.

[0052] like Figure 1 As shown, the device base 1 includes a horizontal plate body 11, which is the main body of the device base and contacts the instrument platform. The two ends of the horizontal plate body 11 are elbows 13, and the elbows 13 cooperate with the threaded fasteners 12. The threaded fasteners 12 are rotated so that the ends thereof can be pressed against the side of the instrument platform to fix the device base 1 to the instrument platform.

[0053] refer to Figure 1-2 As shown, the vertical support rod 2 includes a vertical rod body 21, and the vertical rod body 21 cooperates with a rotating mounting seat 22 at the lower portion so that the vertical rod body 21 can rotate.

[0054] As an improvement, a limit snap mechanism 23 can be provided at the position where the lower part of the vertical rod body 21 cooperates with the mounting seat 22, which is composed of an arc-shaped recess and an arc-shaped protrusion with a telescopic spring. In this example, the arc-shaped recess is provided with the mounting seat 22, and the corresponding arc-shaped protrusion with the telescopic spring is installed at the lower part of the vertical rod body 21. When a large force is applied, the arc-shaped protrusion with the telescopic spring will be squeezed back into the vertical rod body 21, and will no longer hinder the rotation of the vertical rod body 21. When the limit snap mechanism 23 is in the limit state, the vertical rod body 21 is in the initial state, and in the initial state, the vertical rod body 21 is parallel to the outer edge of the instrument table (the outer edge close to the operator).

[0055] refer to Figure 1 , 3 As shown, the crucible clamp 4 includes a crucible clamp holding portion 41 and a crucible clamp handle 42, and the hinged portion 43 of the crucible clamp 4 is installed at both ends of the cross support rod 3. The height of the crucible clamp is set so that when the crucible is clamped, the bottom of the crucible is at the same level or slightly higher than the top of the crucible base A in the initial state. The tension spring 44 between the crucible clamp holding portion 41 provides the clamping power, and a gasket made of polytetrafluoroacetylene material can be added to the inner side of the crucible clamp holding portion 41.

[0056] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
