Description

Technical Field

[0001] This utility model relates to the field of laboratory wastewater treatment technology, specifically to a conventional physicochemical testing wastewater treatment device. Background Technology

[0002] Before conducting multiple tests on wastewater, testing units usually need to adjust the pH value of the wastewater to achieve the required acid-base values ​​for different physicochemical analyses. Currently, pH adjustment generally involves two methods: manual adjustment by laboratory personnel, which is labor-intensive, and the use of an automatic pH control dispensing system such as the Sichen SC-200A (hereinafter referred to as SC-200A). However, machines like the SC-200A rely heavily on the operation of the controller component and peristaltic pump. The controller component is relatively complex to set up, and replacement requires custom ordering from the manufacturer, making it difficult to find simple, readily available alternatives on the market. Furthermore, the wear and tear on the peristaltic pump and piping constitutes a significant portion of later maintenance costs, and unauthorized replacement with peristaltic pumps of other models or brands can negatively impact after-sales service.

[0003] Therefore, a conventional physicochemical testing wastewater treatment device is designed, which is characterized by simple structure, low cost, and low maintenance cost. At the same time, it can use simple control logic and control circuit to realize the function of automatic pH adjustment of wastewater samples. Utility Model Content

[0004] The purpose of this invention is to provide a conventional physicochemical testing wastewater treatment device to solve the problems described in the background art.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A conventional physicochemical testing wastewater treatment device includes a horizontally arranged mounting plate with a support at its bottom. An inwardly extending inlet groove is formed on the side wall of the mounting plate. A magnetic stirring base is located directly below the inlet groove on the mounting plate. A mixing cup is placed on the upper end of the magnetic stirring base, and a stir bar is placed inside the mixing cup. A controller assembly is also provided on the mounting plate. A first mounting column and a second mounting column are vertically arranged on the upper surface of the mounting plate. A first clamp is detachably mounted on the first mounting column, and a second clamp is detachably mounted on the second mounting column. The first clamp is detachably clamped... An online acid-base detector is provided that extends into a mixing cup. A burette is detachably clamped on a second clamp, with the bottom outlet of the burette located directly above the mixing cup. A horizontal mounting post is also provided on a second mounting post, and an electric actuator is detachably mounted horizontally on the horizontal mounting post. An extension plate is detachably mounted at the end of the telescopic rod of the electric actuator, and a cup holder is provided on the extension plate. A liquid receiving cup is removably provided in the cup holder. When the telescopic rod of the electric actuator extends to a preset position, the liquid receiving cup is exactly below the bottom outlet of the burette. The online acid-base detector, the electric actuator, and the controller assembly are electrically connected.

[0007] When using the above method, place the sample to be adjusted into a mixing cup, and then place the mixing cup in the inlet and on the magnetic stirrer. Clamp the online acid-base analyzer onto the first clamp and insert it into the mixing cup. After measuring the pH, select the appropriate acid or base and pour it into the burette. Set the desired pH level using the controller assembly, turn on the magnetic stirrer, and turn on the switch below the burette. The experimenter can then select the titration rate according to their time schedule and can leave to perform other experiments. When the pH of the sample in the mixing cup reaches the preset value, the electric actuator activates, extending the telescopic rod to push the receiving cup below the burette to catch the continuing dripping liquid. Simultaneously, the controller beeps to alert the experimenter, who can then return to the apparatus, close the burette, and check if the pH is within the target range. If there is a slight deviation, a small amount of adjusting solution can be manually added for adjustment.

[0008] The conditioning solution in the receiving cup can be poured back into the burette for next use, or it can be recycled.

[0009] This device has a simple structure and does not require a manufacturer to customize it. It can be assembled by purchasing commonly used parts, resulting in low cost and low maintenance cost. It can automatically adjust the pH value of wastewater samples through simple control logic and control circuits, saving experimental personnel time.

[0010] A further technical solution is that the mounting plate is a rectangular plate, the support part is a support rod, the number of support rods is four and they are respectively located at the four corners of the bottom of the mounting plate, and the insertion groove is opened from the middle of the front end of the mounting plate inward, and the insertion groove is a rectangular groove.

[0011] A further technical solution is that the first clamping member includes a left clamping part, a connecting rod, and a right clamping part. The left clamping part and the right clamping part are respectively fixed at both ends of the connecting rod. The left clamping part of the first clamping member is used to clamp the first mounting post, and the right clamping part of the first clamping member is used to clamp the online acid-base detector.

[0012] A further technical solution is that the second clamping member includes a left clamping part, a connecting rod, and a right clamping part. The left clamping part and the right clamping part are respectively fixed at both ends of the connecting rod. The left clamping part of the second clamping member is used to clamp the second mounting post, and the right clamping part of the first clamping member is used to clamp the burette.

[0013] A further technical solution is that the left clamping part includes a U-shaped plate and a locking bolt. The U-shaped plate consists of two opposing plates and a connecting plate connecting the two opposing plates. One end of the U-shaped plate is fixed to one end of the connecting rod, and the locking bolt is screwed through the other end of the U-shaped plate.

[0014] A further technical solution is that the right clamping part includes a rectangular fixed clamping block and a rectangular movable clamping block. The rear side of the fixed clamping block is fixed to the connecting rod, and the front side of the fixed clamping block has an arc-shaped groove. Slide rods are also fixed on the left and right sides of the front side of the fixed clamping block, respectively. The movable clamping block is located at the front end of the fixed clamping block. The rear side of the movable clamping block has an arc-shaped groove. Two through holes are opened between the front and rear sides of the movable clamping block, which respectively correspond to the slide rods. The slide rods pass through the through holes and extend forward out of the movable clamping block. The arc-shaped grooves of the fixed clamping block and the arc-shaped grooves of the movable clamping block enclose each other to form a clamping area. A spring is also sleeved on the slide rod at the front end of the movable clamping block. The wall of the slide rod is also provided with external threads. A nut is also screwed onto the slide rod at the front end of the spring.

[0015] When using the above scheme, the compression of the spring is adjusted by using a nut, thereby adjusting the clamping force between the moving clamp and the fixed clamp, which facilitates proper clamping of the burette and the online acid-base detector.

[0016] A further technical solution is that rubber pads are fixedly provided on the arc-shaped grooves of the fixed clamping block and the arc-shaped grooves of the moving clamping block to cover the groove surfaces of the arc-shaped grooves.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. Experimenters can choose the titration rate according to their own time plan, and can leave to carry out other experimental operations during the titration period.

[0019] 2. When the sample pH reaches the preset value, the electric actuator pushes the receiving cup to collect the liquid, and the controller emits a buzzer to remind the experimenter.

[0020] 3. If the pH level is slightly off, a small amount of adjusting solution can be added manually to adjust it.

[0021] 4. The structure is simple, requiring no full-package customization. Commonly used parts can be purchased and assembled independently, resulting in low manufacturing and maintenance costs.

[0022] 5. It can automatically adjust the pH value of wastewater samples through simple control logic and circuits, saving experimental personnel time. Attached Figure Description

Detailed Implementation

[0028] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0029] See Figures 1 to 4 A conventional physicochemical testing wastewater treatment device includes a horizontally arranged rectangular mounting plate 2, which can be made of PP board, PVC board or nylon plastic board.

[0030] The bottom of the mounting plate 2 is provided with a support part. Specifically, the support part is a support rod 1 made of the same material as the mounting plate 2. There are four support rods 1, which are respectively located at the four corners of the bottom of the mounting plate 2. They are fixed and installed by adhesive or by plastic welding.

[0031] The side wall of the mounting plate 2 is provided with an inwardly extending insertion groove 3. The insertion groove 3 is opened from the middle of the front end of the mounting plate 2 inward and is a rectangular groove.

[0032] A magnetic stirring base 4 is located below the mounting plate 2, which is placed directly below the slot 3. The magnetic stirring base 4 can be a product from the existing technology, and its height should be suitable enough to fit under the mounting plate 2.

[0033] A mixing cup 5 is placed on the upper end of the magnetic stirring base 4, and a stir bar 17 is installed in the mixing cup 5. The stir bar 17 is wrapped with polytetrafluoroethylene plastic or other materials that do not react with acids and alkalis.

[0034] The mounting plate 2 also includes a controller assembly 6. The controller assembly 6 includes a simple display with control buttons, a SMART200 PLC controller, and a buzzer (some SMART200 PLC controllers have a built-in buzzer). The online acid-base detector 7 is electrically connected to the controller, the controller is electrically connected to the display, and the electric actuator 12 is electrically connected to the controller. The control program is as follows: after setting the corresponding acid-base conversion for the output current of the online acid-base detector 7 in the controller (this is existing technology and will not be elaborated further), the operator sets the acid-base warning value through the display. When the measured value exceeds the warning value, the controller activates the electric actuator 12 and the buzzer.

[0035] The upper surface of the mounting plate 2 is also vertically provided with a first mounting post 8 and a second mounting post 10. Preferably, the first mounting post 8 and the second mounting post 10 can be made of square aluminum profiles with a specification of 20-20, and the bottom of the first mounting post 8 and the second mounting post 10 are fixed to the mounting plate 2 by screwing.

[0036] A first clamp 9 is detachably mounted on the first mounting post 8, and a second clamp 15 is detachably mounted on the second mounting post 10. An online acid-base detector 7 that extends into the mixing cup 5 is detachably clamped on the first clamp 9, and a burette 16 is detachably clamped on the second clamp 15. The bottom outlet of the burette 16 is located directly above the mixing cup 5.

[0037] It should be noted that there are many options for the first clamp 9 and the second clamp 15. Existing clamps already on the market, such as test tube clamps, three-jaw clamps, spring clamps, and push-button clamps, can be used, as long as they have the function of clamping the mounting post at one end and the tubular object at the other. Alternatively, the self-made first clamp 9 and second clamp 15 of this disclosure can also be used.

[0038] Specifically, the self-made first clamp 9 and second clamp 15 in this disclosure both include a left clamping part, a connecting rod 21, and a right clamping part, which are respectively fixed at both ends of the connecting rod 21. The left clamping part of the first clamp 9 is used to clamp the first mounting post 8, and the right clamping part of the first clamp 9 is used to clamp the online acid-base detector 7. The left clamping part of the second clamp 15 is used to clamp the second mounting post 10, and the right clamping part of the first clamp 9 is used to clamp the burette 16.

[0039] Specifically, the left clamping part includes a U-shaped plate 19 and a locking bolt 20. The U-shaped plate 19 consists of two opposing plates and a connecting plate connecting the two opposing plates. One end of the U-shaped plate 19 is fixed to one end of the connecting rod 21, and the locking bolt is screwed through the other end of the U-shaped plate 19.

[0040] Specifically, the clamping part includes a rectangular fixed clamping block 22 and a rectangular movable clamping block 24. The rear side of the fixed clamping block 22 is fixed to the connecting rod 21. The front side of the fixed clamping block 22 has an arc-shaped groove. The left and right sides of the arc-shaped groove of the fixed clamping block 22 are respectively fixed with sliding rods 23. The movable clamping block 24 is located at the front end of the fixed clamping block 22. The rear side of the movable clamping block 24 has an arc-shaped groove. There are two through holes between the front and rear sides of the movable clamping block 24, which are respectively matched with the sliding rods 23. The sliding rods 23 pass through the through holes and extend forward out of the movable clamping block 24. The arc-shaped groove of the fixed clamping block 22 and the movable clamping block 24 and the arc-shaped groove surround each other to form a clamping area. A spring 25 is also sleeved on the sliding rod 23 at the front end of the movable clamping block 24. The wall of the sliding rod 23 is also provided with external threads. A nut 26 is also screwed onto the sliding rod 23 at the front end of the spring 25.

[0041] The second mounting post 10 is also horizontally mounted with a horizontal mounting post 11, on which an electric actuator 12 is detachably and horizontally mounted. Specifically, the horizontal mounting post 11 can be made of a 20-20mm square aluminum profile, connected to the second mounting post 10 via corresponding connectors. Alternatively, the horizontal mounting post 11 can be made of a bent thin plate. The electric actuator 12 is adjusted and mounted on the aluminum profile or thin plate via corresponding connection holes. These connection methods are relatively easy to implement in the prior art, and the specific connection methods will not be limited or described in detail here.

[0042] An extension plate 18 is detachably mounted on the end of the telescopic rod of the electric actuator 12. A cup holder 13 is provided on the extension plate 18, and a liquid receiving cup 14 is removably mounted within the cup holder 13. The extension plate 18 is selected based on the orientation of the hole in the telescopic rod of the electric actuator 12. If the hole in the electric actuator 12 is on the side, an 'L'-shaped extension plate 18 can be selected; if the hole in the telescopic rod of the electric actuator 12 is on top, a long strip-shaped extension plate 18 can be selected. The purpose of the extension plate 18 is to position the cup holder 13 along the movement path below the bottom outlet of the burette 16. The cup holder 13 can be made of acid- and alkali-resistant plastic and is fixed to the extension plate 18 by screwing or gluing. The liquid receiving cup 14 is preferably a glass cup, slightly smaller than and higher than the cup holder 13, for easy insertion and removal.

[0043] When the telescopic rod of the electric actuator 12 extends to the preset position, the liquid receiving cup 14 is exactly below the bottom outlet of the burette 16.

[0044] Preferably, rubber pads 27 are also fixed on the arc grooves of the fixed clamping block 22, the arc groove, and the moving clamping block 24 to cover the groove surface of the arc groove.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
