A water quality testing additive structure

Abstract

This utility model discloses a water quality testing additive addition structure, including an addition mechanism. The addition mechanism includes a fixed cylinder with a piston inside. A connecting rod is fixed to the bottom of the piston, and a movable plate is fixed to the bottom of the connecting rod. A storage tank is located on the left side of the fixed cylinder, and a fixed frame and a fixed plate are fixed to the outer wall of the storage tank. The motor is started, causing a lifting screw to rotate. The rotation of the lifting screw moves the movable plate, connecting rod, and piston, creating negative pressure inside the fixed cylinder and drawing out the formaldehyde remover from the storage tank. After drawing, the cylinder is rotated according to the required amount, moving the movable plate. The movable plate is moved to the designated height by observing the scale. The valve stem is rotated to adjust the valve core direction. The motor is then started in reverse, causing the lifting screw to rotate in reverse as well. This causes the movable plate, connecting rod, and piston to rise, and the piston forces the formaldehyde remover inside the fixed cylinder into the outlet pipe, which then enters the water.

Description

Technical Field

[0001] This utility model relates to the field of additive technology, specifically to a water quality testing additive structure. Background Technology

[0002] Water is one of the most common substances on Earth. It is an essential resource for the survival of all life, including humans, and is the most important component of organisms. It has played a vital role in the evolution of life and is therefore known as the source of life.

[0003] With the development of technology, water is now divided into different purities (such as ultrapure water, pure water, and tap water). However, water also has a shelf life. Therefore, it is necessary to add formaldehyde removal agents to water to extend its shelf life. However, adding formaldehyde removal agents requires precise dosage to ensure accurate test results. Therefore, a water quality testing additive structure is needed that can quickly and accurately add a quantitative amount of formaldehyde removal agent to water of different purities. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a water quality testing additive structure that solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water quality testing additive addition structure, comprising an addition mechanism, the addition mechanism comprising a fixed cylinder, a piston disposed inside the fixed cylinder, a connecting rod fixed to the bottom of the piston, a movable plate fixed to the bottom of the connecting rod, a storage tank disposed on the left side of the fixed cylinder, a fixed frame and a fixed plate fixed to the outer wall of the storage tank, the fixed frame and the fixed cylinder being fixedly connected, and a lifting screw screw being screwed into the interior of the movable plate;

[0006] The two ends of the lifting screw are rotatably connected to the fixed frame and the fixed plate, respectively. A motor is fixed to the bottom of the fixed plate. The output shaft of the motor is fixedly connected to the lifting screw. A fixing screw is fixed between the fixed plate and the fixed frame. The fixing screw passes through the moving plate. A cylinder is screwed to the outer wall of the fixing screw. A movable plate is rotatably connected to the outer wall of the cylinder. A movable groove is opened at the top of the movable plate. A limiting rod is provided inside the movable groove.

[0007] The two ends of the limiting rod are fixedly connected to the fixed frame and the fixed plate, respectively. The right side of the limiting rod is provided with a scale. The top of the fixed cylinder is fixed with a valve body. The valve body is provided with a valve core. The valve body is rotatably connected with a valve rod. The bottom of the valve rod is fixedly connected to the valve core. The two ends of the valve body are fixed with a liquid extraction pipe and a liquid outlet pipe, respectively. The other end of the liquid extraction pipe is fixedly connected to the storage tank.

[0008] Preferably, an iron bar is fixed inside the limiting rod, and a magnetic block is fixed inside the movable groove.

[0009] Preferably, a nut is screwed onto the outer wall of the fixing screw, and the bottom of the nut is fixedly connected to the top of the cylinder.

[0010] Preferably, the bottom of the storage tank is fixed with multiple support legs.

[0011] Preferably, both the suction tube and the discharge tube are rubber hoses.

[0012] Preferably, the fixing screw does not contact the moving plate.

[0013] This invention provides a water quality testing additive structure. Compared with the prior art, it has the following advantages:

[0014] This water quality testing additive addition mechanism, through its added structure, involves starting a motor that drives a lifting screw. The screw's rotation moves a moving plate, connecting rod, and piston, creating negative pressure inside the fixed cylinder to extract the formaldehyde remover from the storage tank. After extraction, the cylinder is rotated to add the required amount, moving the moving plate along with it. The scale is then used to move the moving plate to the designated height. The valve stem is rotated to adjust the valve core's direction, and the motor is started in reverse. This reverses the motor and the lifting screw, causing the moving plate, connecting rod, and piston to rise. The piston forces the formaldehyde remover from the fixed cylinder into the outlet pipe, which then enters the water. The water is then tested to understand the impact of different amounts of formaldehyde remover on the water's shelf life. Attached Figure Description

[0021] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a water quality testing additive addition structure, including an addition mechanism 4. The addition mechanism 4 includes a fixed cylinder 408, inside which is a piston 410. A connecting rod 409 is fixed to the bottom of the piston 410, and a moving plate 407 is fixed to the bottom of the connecting rod 409. A storage tank 2 is located on the left side of the fixed cylinder 408. A fixed frame 406 and a fixed plate 402 are fixed to the outer wall of the storage tank 2. The fixed frame 406 and the fixed cylinder 408 are fixedly connected. A lifting screw 403 is screwed into the moving plate 407. The two ends of the lifting screw 403 are rotatably connected to the fixed frame 406 and the fixed plate 402, respectively. A motor 401 is fixed to the bottom of the fixed plate 402. The output shaft of the motor 401 is fixedly connected to the lifting screw 403. A fixing screw 405 is fixed between the fixed plate 402 and the fixed frame 406. A fixed screw 405 passes through a movable plate 407. A cylinder 416 is screwed to the outer wall of the fixed screw 405. A movable plate 413 is rotatably connected to the outer wall of the cylinder 416. A movable groove 415 is opened at the top of the movable plate 413. A limiting rod 404 is provided inside the movable groove 415. The two ends of the limiting rod 404 are fixedly connected to the fixed frame 406 and the fixed plate 402, respectively. A scale 411 is provided on the right side of the limiting rod 404. A valve body 5 is fixed to the top of the fixed cylinder 408. A valve core 7 is provided inside the valve body 5. A valve stem 8 is rotatably connected inside the valve body 5. The bottom of the valve stem 8 is fixedly connected to the valve core 7. A liquid extraction pipe 6 and a liquid outlet pipe 3 are fixed to the two ends of the valve body 5, respectively. The other end of the liquid extraction pipe 6 is fixedly connected to the storage tank 2. This allows for the accurate and rapid addition of the same amount of formaldehyde remover to water of different levels, thereby testing the effect of the formaldehyde remover on the shelf life of different types of water.

[0023] Furthermore, an iron strip 414 is fixed inside the limiting rod 404, and a magnetic block 412 is fixed inside the movable groove 415, which can restrict the movement of the movable plate 413. A nut 417 is screwed onto the outer wall of the fixing screw 405, and the bottom of the nut 417 is fixedly connected to the top of the cylinder 416, which facilitates the rotation of the cylinder 416. Multiple support legs 1 are fixed to the bottom of the storage tank 2, which can raise the height of the storage tank 2. The liquid extraction pipe 6 and the liquid outlet pipe 3 are both rubber hoses, which facilitates the movement and connection of the pipes. The fixing screw 405 does not contact the movable plate 407, so the fixing screw 405 will not obstruct the movement of the movable plate 407.

[0024] During operation, start motor 401. Motor 401 drives lifting screw 403 to rotate. The rotation of lifting screw 403 causes moving plate 407, connecting rod 409, and piston 410 to move. The movement of piston 410 creates negative pressure inside fixed cylinder 408, extracting formaldehyde removal agent from storage tank 2. After extraction, rotate cylinder 416 to add the required amount. Cylinder 416 moves movable plate 413. Observe scale 411 and move movable plate 413 to the designated height. Rotate valve stem 8 to adjust the direction of valve core 7. Start motor 401. 1. Reverse rotation: Motor 401 drives lifting screw 403 to reverse rotation, causing moving plate 407, connecting rod 409, and piston 410 to rise. Piston 410 squeezes the formaldehyde removal agent inside fixed cylinder 408 into outlet pipe 3, which then enters the water. Once moving plate 407 and movable plate 413 come into contact, moving plate 407, connecting rod 409, and piston 410 stop moving. This allows for the addition of a fixed amount of formaldehyde removal agent to water of different purities. Then, the water of different purities can be tested to understand the impact of accurately adding different amounts of formaldehyde removal agent on the shelf life of different types of water.
