Description

Technical Field

[0001] The present invention relates to the technical field of the preparation of anhydrous sodium acetate, and particularly to a water pollution detection device for the preparation of anhydrous sodium acetate. Background Technique

[0002] In recent years, with the development of new energy technologies, anhydrous sodium acetate has been developed as a new phase change energy storage material due to its high heat capacity and thermal conductivity, and is applied to fields such as solar heat storage systems and industrial waste heat recovery. Driven by nanotechnology, it is used as a precursor for the preparation of high-performance composite new materials, such as catalytic carriers, biosensors, etc. During the preparation of anhydrous sodium acetate, the water pollution detection device is mainly used to monitor the purity of raw water, the pollutants in reaction wastewater, and the quality of the final discharged water to ensure environmental protection compliance and product quality.

[0003] Currently, when detecting water pollution during the preparation of anhydrous sodium acetate, a spectrophotometer is usually used to detect and analyze samples. However, during the operation process, the sample dish needs to be placed in the rack inside the spectrophotometer. Since the rack is located inside the spectrophotometer and the operating space around it is small, it is inconvenient to place multiple sample dishes and colorimetric dishes as a whole. Summary of the Invention

[0004] The purpose of the present invention is to provide a water pollution detection device for the preparation of anhydrous sodium acetate to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A water pollution detection device for the preparation of anhydrous sodium acetate, including a spectrophotometer main body and a feeding component. A detection cavity is provided inside the spectrophotometer main body, and the feeding component is arranged inside the detection cavity. The feeding component includes a damping rotating shaft. The upper part of the spectrophotometer main body is connected with a damping rotating shaft, and a cover plate is arranged outside the damping rotating shaft. The bottom surface of the cover plate is rotationally connected with a connecting rod, and the lower end of the connecting rod is rotationally connected with a guide rail. The two ends of the guide rail are internally slidably connected with light rods, and rubber blocks are fixed inside the two ends of the guide rail. One side of the guide rail is slidably connected with a slider, and a placement rack is fixed on one side of the slider. Translucent holes are provided on both sides of the middle part of the placement rack.

[0006] Further, the light rods are fixedly connected with the spectrophotometer main body, and the number of the light rods is four.

[0007] Further, the cross-section of the slider is an isosceles trapezoid, and the sliders are symmetrically distributed about the center line of the placement rack.

[0008] Further, a clamping assembly is connected to the top of the storage rack. The clamping assembly includes fixed ears. The fixed ears are symmetrically arranged at both ends of the top of the storage rack. A sliding column is slidably connected inside the fixed ear. A compression spring is sleeved outside the sliding column. One end of the sliding column is fixed with a clamping plate. The end of the compression spring abuts against the clamping plate. Rubber pads are arranged at equal intervals on one side of the clamping plate.

[0009] Further, a driving plate is fixed in the middle of the other side of the clamping plate. A ball is arranged at the end of the driving plate. Guide plates are symmetrically fixed on both sides inside the detection cavity. The cross section of the guide plate is in the shape of a right trapezoid.

[0010] Further, an adjusting assembly is connected to one end of the storage rack. The adjusting assembly includes a connecting plate. The connecting plate is slidably connected to one end of the storage rack. A screw rod is arranged on one side of the connecting plate. A screw sleeve is threadedly connected to the outer side of one end of the screw rod. The screw sleeve is rotatably connected to the spectrophotometer main body. A one-way bearing is arranged on the outer side of the screw sleeve. A gear is fixed on the outer side of the one-way bearing.

[0011] Further, a fixing plate is fixed on one side of the spectrophotometer main body. A sliding rod is slidably connected inside the fixing plate. A return spring is sleeved outside the sliding rod. An anti-slip plate abuts against the top of the return spring.

[0012] Further, the anti-slip plate is fixedly connected to the sliding rod and is slidably connected to the spectrophotometer main body.

[0013] Further, a rack is arranged at one end of the bottom of the anti-slip plate. A limiting plate is arranged between the sliding rod and the rack. The limiting plate is fixedly connected to the spectrophotometer main body.

[0014] Further, the number of both the rack and the gear is two, and the rack and the gear correspond to each other one by one.

[0015] The present invention provides a water pollution detection device for the preparation of sodium acetate anhydride, having the following beneficial effects:

[0016] 1. In the present invention, the storage rack is automatically lifted and lowered through the linkage of the damping rotating shaft and the connecting rod. When the operator opens the cover plate, the storage rack automatically moves out of the detection cavity to form a spacious operation space. The friction between the rubber block and the optical rod and the damping rotating shaft form gravity self-locking to realize the hovering positioning function. When the cover plate is closed, the storage rack automatically returns to its position and is accurately aligned with the optical path system. This structure makes it easier to operate the sample dish, and the opening and closing actions are synchronized with the calibration of the detection position, significantly improving the detection preparation efficiency.

[0017] 2. The storage rack of the present invention is configured with a clamping component. When the storage rack is moved out of the detection chamber, the clamping plates automatically unfold to form a large-opening placement groove, enabling the rapid insertion and loading of sample dishes. During the retraction process, the clamping plates are driven to be centered and clamped through the inclined surface of the guide plate, ensuring the positioning accuracy of the sample during detection. This design combines the convenience of loading and the stability of detection. The dual-state automatic switching mechanism reduces two manual steps in the operation process, not only improving the single detection speed but also preventing the optical path deviation caused by the tilting of the sample.

[0018] 3. The displacement control structure of the present invention adopts a one-way bearing in cooperation with a gear-rack drive. The push-type anti-slip plate realizes step control, and each trigger completes a preset pitch movement, ensuring that the sample dish precisely traverses all detection positions. Compared with the traditional pull rod mechanism, it eliminates the human dragging error. The mechanical interlock design of the return spring and the limit plate guarantees the repeatability of the displacement. This structure improves the positioning accuracy of continuous detection of multiple samples, while reducing the skill requirements of operators, and has obvious advantages in the rapid comparison detection scenario.

DETAILED DESCRIPTION

[0026] See also Figures 1 to 4 The present invention provides a technical solution: a device for detecting water pollution for preparing anhydrous sodium acetate, comprising a spectrophotometer body 1 and a feeding assembly 3, wherein a detection chamber 2 is arranged inside the spectrophotometer body 1, and the feeding assembly 3 is arranged inside the detection chamber 2, and the feeding assembly 3 comprises a damping shaft 301, the upper part of the spectrophotometer body 1 is connected with the damping shaft 301, and the outer side of the damping shaft 301 is provided with a cover plate 302, the bottom surface of the cover plate 302 is rotatably connected with a connecting rod 303, and the lower end of the connecting rod 303 is rotatably connected with a guide rail 30 4. Optical rods 305 are slidably connected to the two ends of the guide rail 304, and rubber blocks 306 are fixed to the two ends of the guide rail 304, and a slider 307 is slidably connected to one side of the guide rail 304, a storage rack 308 is fixed to one side of the slider 307, and light holes 309 are opened on both sides of the middle of the storage rack 308, the optical rods 305 are fixedly connected to the spectrophotometer body 1, and the number of optical rods 305 is set to four, the cross section of the slider 307 is an isosceles trapezoid, and the sliders 307 are symmetrically distributed about the center line of the storage rack 308;

[0027] The specific operation is as follows. When placing the sample dish, first open the cover plate 302, and make it rotate around the damping rotating shaft 301 to the open state. During this process, the cover plate 302 will pull the guide rail 304 through the connecting rod 303, making it slide upward along the optical rod 305, and automatically move the storage rack 308 out of the detection chamber 2, so that there is a larger operating space outside the storage rack 308, making it more convenient to place the sample dish inside the storage rack 308 and easier to observe. At the same time, the rubber block 306 will increase the friction between the guide rail 304 and the optical rod 305, and combine with the damping of the damping rotating shaft 301 to offset the gravity of the storage rack 308, so that after the cover plate 302 rotates, the height of the storage rack 308 can be automatically positioned without continuous support by personnel, which is labor-saving and convenient. And after placing, just close the cover plate 302, and during the process of covering the top of the detection chamber 2, the cover plate 302 can push the guide rail 304 through the connecting rod 303, making it drive the storage rack 308 to move downward along the optical rod 305, and automatically move the storage rack 308 into the detection chamber 2, so that one of the light-transmitting holes 309 on the storage rack 308 is accurately aligned with the optical path system in the spectrophotometer main body 1. Therefore, during the opening and closing of the cover plate 302, the storage rack 308 can be automatically lifted and lowered synchronously without additional operations, which is beneficial to improving the convenience of taking and placing the sample dish and improving the water pollution detection efficiency.

[0028] Please refer to Figure 5 , a clamping component 4 is connected to the top of the storage rack 308, and the clamping component 4 includes fixed ears 401. The fixed ears 401 are symmetrically arranged at both ends of the top of the storage rack 308, and a sliding column 402 is slidably connected inside the fixed ears 401. A compression spring 403 is sleeved outside the sliding column 402, and a clamping plate 404 is fixed at one end of the sliding column 402. The end of the compression spring 403 abuts against the clamping plate 404, and rubber pads 405 are arranged at equal intervals on one side of the clamping plate 404. A driving plate 406 is fixed in the middle of the other side of the clamping plate 404, and a ball 407 is arranged at the end of the driving plate 406. Guide plates 408 are symmetrically fixed on both sides inside the detection chamber 2, and the cross section of the guide plate 408 is a right trapezoid;

[0029] The specific operation is as follows. After the storage rack 308 is removed from the detection chamber 2, since the end of the driving plate 406 is not blocked, the compression spring 403 will push the end of the sliding column 402 under the limit of the fixed ear 401, causing the clamping plates 404 on both sides to move away from each other. At this time, since the opening of the placement groove on the storage rack 308 is relatively large, it is convenient to insert the sample dish into the storage rack 308 without careful docking, thereby improving the convenience during placement and accelerating the picking and placing speed of the sample dish. Subsequently, during the downward movement of the storage rack 308, the driving plate 406 will also be driven to move downward synchronously. At this time, the ball 407 moves along the inclined plane trajectory of the guide plate 408, and the driving plate 406 can be controlled to push the clamping plates 404 to centrally clamp the placed sample dish, automatically align and correct it, avoiding the sample dish from tilting during subsequent detection and improving the detection accuracy of the sample. Subsequently, when changing the position of the sample dish to detect different samples, the stability of the sample dish during translation can also be enhanced. And after detection, when the sample dish needs to be taken out, during the upward movement of the storage rack 308, similarly, the two clamping plates 404 will be automatically separated without additional operations, further improving the convenience during use.

[0030] Please refer to Figure 6 , one end of the storage rack 308 is connected with an adjustment component 5, and the adjustment component 5 includes a connecting plate 501. One end of the storage rack 308 is slidably connected with the connecting plate 501, and a screw rod 502 is arranged on one side of the connecting plate 501. The outer side of one end of the screw rod 502 is threadedly connected with a nut sleeve 503, and the nut sleeve 503 is rotationally connected with the spectrophotometer main body 1. A one-way bearing 504 is arranged on the outer side of the nut sleeve 503, and a gear 505 is fixed on the outer side of the one-way bearing 504. A fixed plate 506 is fixed on one side of the spectrophotometer main body 1, and a sliding rod 507 is slidably connected inside the fixed plate 506. A return spring 508 is sleeved on the outer side of the sliding rod 507, and an anti-slip plate 509 is abutted against the top of the return spring 508. The anti-slip plate 509 is fixedly connected with the sliding rod 507 and is slidably connected with the spectrophotometer main body 1. One end of the bottom of the anti-slip plate 509 is provided with a rack 510. A limiting plate 511 is arranged between the sliding rod 507 and the rack 510, and the limiting plate 511 is fixedly connected with the spectrophotometer main body 1. The number of both the rack 510 and the gear 505 is set to two, and the rack 510 and the gear 505 correspond to each other one by one;

[0031] The specific operation is as follows. During the lifting process of the storage rack 308, it will also slide along the outer side of the connecting plate 501, which is beneficial to enhancing the stability of the storage rack 308 during the lifting process. When it is necessary to adjust the position of the storage rack 308 to detect the next sample dish in the storage rack 308, only need to press the anti-slip plate 509 on the left, so that the rack 510 contacts the gear 505 and drives it to rotate. At this time, the inner and outer rings of the one-way bearing 504 in the gear 505 are in a locked state, and the nut sleeve 503 can be driven to rotate together, thereby controlling the screw 502 to move forward, so that the connecting plate 501 pulls the storage rack 308 forward. And when the anti-slip plate 509 fits with the limit plate 511, the next light-transmitting hole 309 of the storage rack 308 will just be located between the light source and the receiver, so as to detect the next sample dish. And after letting go, the return spring 508 will push the anti-slip plate 509 under the limit of the fixed plate 506, so that the rack 510 moves up and resets. When the gear 505 rotates in the reverse direction, the inner and outer rings of the one-way bearing 504 will not transmit power. Therefore, when changing the front and back positions of the sample dish, only need to press the left and right anti-slip plates 509 according to the needs. Compared with the existing spectrophotometer directly pulled and controlled by a pull rod, in this application, since the displacement amount is accurately controlled according to the preset pitch each time, it is easier to control the moving distance of the sample dish, and further improves the accuracy during detection.

[0032] In summary, for this water pollution detection device for the preparation of anhydrous sodium acetate, when in use, first open the cover plate 302. During this process, the cover plate 302 will pull the guide rail 304 through the connecting rod 303, so that it slides upward along the optical rod 305. At the same time, during the lifting process of the storage rack 308, it will also slide along the outer side of the connecting plate 501, enhancing the stability of the storage rack 308 during the lifting process. And after the storage rack 308 is moved out of the detection cavity 2, since there is a large operating space on the outer side of the storage rack 308, it is more convenient to put the sample dish into the storage rack 308 and easier to observe. At the same time, the rubber block 306 will increase the friction between the guide rail 304 and the optical rod 305, and combine with the damping of the damping rotating shaft 301 to offset the gravity of the storage rack 308, so that after the cover plate 302 rotates, the height of the storage rack 308 can be automatically positioned without continuous support by personnel, which is labor-saving and convenient;

[0033] Secondly, when the storage rack 308 is moved out of the detection cavity 2, since the end of the driving plate 406 has no obstruction, the compression spring 403 will push the end of the sliding column 402 under the limit of the fixed ear 401, so that the two clamping plates 404 move away from each other. At this time, since the opening of the placement groove on the storage rack 308 is large, it is convenient to insert the sample dish into the storage rack 308 without careful docking, thereby improving the convenience during placement and accelerating the picking and placing speed of the sample dish;

[0034] Next, after placement, simply close the cover plate 302. During the process of covering the top of the detection chamber 2, the cover plate 302 will push the guide rail 304 through the connecting rod 303, causing it to drive the storage rack 308 to move downward along the optical rod 305, automatically moving the storage rack 308 into the detection chamber 2, so that one of the light-transmitting holes 309 on the storage rack 308 is accurately aligned with the optical path system in the spectrophotometer main body 1. Therefore, during the opening and closing of the cover plate 302, the storage rack 308 can be automatically lifted and lowered synchronously without additional operations, which is beneficial to improving the convenience of taking and placing the sample dish;

[0035] Then, during the downward movement of the storage rack 308, it will also drive the drive plate 406 to move downward synchronously. At this time, the ball 407 moves along the inclined plane track of the guide plate 408, which can control the drive plate 406 to push the clamping plate 404 to centrally clamp the placed sample dish, automatically align and correct it, avoiding the sample dish from tilting during subsequent detection and improving the detection accuracy of the sewage sample;

[0036] Finally, when it is necessary to detect the next sample dish in the storage rack 308, simply press the anti-slip plate 509 on the left, so that the rack 510 contacts the gear 505 and drives it to rotate. At this time, the inner and outer rings of the one-way bearing 504 in the gear 505 are in a locked state, which can drive the nut sleeve 503 to rotate together, thereby controlling the screw rod 502 to move forward, causing the connecting plate 501 to pull the storage rack 308 forward. And when the anti-slip plate 509 fits with the limit plate 511, the next light-transmitting hole 309 on the storage rack 308 will just be located between the light source and the receiver for detecting the next sample dish. After releasing the hand, the return spring 508 will push the anti-slip plate 509 under the limitation of the fixed plate 506, causing the rack 510 to move upward and reset. When the gear 505 rotates in the reverse direction, the inner and outer rings of the one-way bearing 504 will not transmit power. Therefore, when changing the front and back positions of the sample dish, simply press the left and right anti-slip plates 509 according to the needs.
