DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-4 A chemical oxygen demand acid adding tool is shown, comprising a container 1, a top cover 3 is arranged on the top of the container 1, a first baffle 4 is fixedly connected to the inner wall of the middle part of the container 1, a first liquid drop hole 5 is opened on one side of the first baffle 4, a rubber plug 6 for adjusting the liquid drop speed is arranged on the bottom of the first baffle 4, a moving component is arranged on one side of the rubber plug 6, an identification component for observing the moving distance of the rubber plug 6 is arranged on one side of the container 1, a scale line 2 is arranged on one side of the container 1, and a supporting component for supporting the rubber plug 6 is arranged at the bottom of the rubber plug 6.

[0022] It should be noted that the shape of the container 1 is conical, and a hole for liquid outflow is provided at its bottom. The container 1 is divided into two upper and lower spaces by the first baffle 4. The top of the first baffle 4 is used to store silver sulfate-sulfuric acid liquid. The rubber plug 6 is used to block the first drop hole 5 on the first baffle 4. When the liquid does not need to fall from the first drop hole 5, the rubber plug 6 is moved to the bottom of the first drop hole 5 and the first drop hole 5 is blocked to prevent the liquid from flowing downward. The rubber plug 6 is made of rubber. When in use, the silver sulfate-sulfuric acid liquid is stored in the container 1, and then the first drop hole 5 is opened by moving the rubber plug 6 so that the liquid falls from the first drop hole 5. The moving distance of the rubber plug 6 is observed by the identification component to control the size of the first drop hole 5. When in use, the flow rate and flow rate of the liquid are determined by determining the size of the first drop hole 5, thereby improving the accuracy of the detection result.

[0023] Specifically, the moving component includes a threaded hole 7 opened on one side of the rubber stopper 6, a threaded rod 8 is threadedly inserted and connected to one side of the threaded hole 7, and a twist cap 9 for rotating the threaded rod 8 is fixedly connected to one end of the threaded rod 8. A limiting member for limiting the displacement of the threaded rod 8 is provided on one side of the container 1, and the limiting member includes a support seat 10 fixedly connected to one side of the container 1, and the threaded rod 8 is rotatably inserted and connected to the middle part of the support seat 10. A bearing 11 is inserted and connected to one side of the support seat 10, and the bearing 11 is sleeved in the middle part of the threaded rod 8.

[0024] It should be noted that the outer groove ring of the bearing 11 is fixedly inserted and connected to one side of the support seat 10, and the inner groove ring is fixedly sleeved in the middle of the threaded rod 8. The position of the threaded rod 8 is fixed by the bearing 11 in a fixed position to avoid the horizontal movement of the threaded rod 8 during use. When the threaded rod 8 needs to be rotated, the threaded rod 8 drives the inner groove ring of the bearing 11 to rotate, so as to fix the threaded rod 8 without affecting the rotation of the threaded rod 8; the top of the rubber stopper 6 and the bottom of the first baffle 4 are both flat, and the top of the rubber stopper 6 and the bottom of the first baffle 4 are in contact, and the bottom of the rubber stopper 6 is supported by the support assembly, so that the rubber stopper 6 is clamped and fixed by the extrusion assembly and the first baffle 4, so that it cannot rotate.

[0025] Furthermore, the twist cap 9 is rotated, and the twist cap 9 drives the threaded rod 8 to rotate, and the threaded rod 8 drives the rubber plug 6 which is threadedly connected to it and cannot rotate to move. When liquid needs to be dropped, the rubber plug 6 is moved toward the twist cap 9. When liquid is not needed to be dropped, the rubber plug 6 is moved to the side away from the twist cap 9.

[0026] Specifically, the identification component includes a reading threaded sleeve 16 threadedly sleeved in the middle of the threaded rod 8 , one side of the support seat 10 is fixedly connected to the benchmark rod 12 , and the reading threaded sleeve 16 is sleeved on one side of the benchmark rod 12 .

[0027] It should be noted that a numerical value is set on the benchmark 12 for recording the moving distance of the reading threaded sleeve 16. The reading threaded sleeve 16 is restricted by the fixed position threaded rod 8 and the benchmark 12, so that it cannot rotate. Therefore, when the threaded rod 8 rotates, the reading threaded sleeve 16 moves together with the rubber stopper 6, and the moving distance is consistent. By setting the moving distance numerical value corresponding to the liquid falling speed on the benchmark 12, the moving distance of the rubber stopper 6 can be controlled by observing the moving distance of the reading threaded sleeve 16, thereby controlling the liquid falling speed.

[0028] Specifically, the support assembly includes a second baffle 14 fixedly connected to the inner wall of the middle part of the container 1, a second liquid drop hole 15 is opened on one side of the second baffle 14, a blocking block 13 is fixedly connected to the bottom of the first baffle 4, the blocking block 13 is fixedly connected to the top of the second baffle 14, and the blocking block 13 is fixedly connected to the inner wall of one side of the container 1.

[0029] It should be noted that the blocking block 13 is arranged on one side of the rubber stopper 6 to prevent the silver sulfate-sulfuric acid liquid from flowing into between the first baffle 4 and the second baffle 14, thereby preventing the liquid from remaining between the first baffle 4 and the second baffle 14. The second baffle 14 and the first baffle 4 are used to clamp the position of the rubber stopper 6.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
