Description

Technical Field

[0001] This application relates to the field of TOC measuring instruments, and in particular to a device and method for measuring total organic carbon in drinking water. Background Technology

[0002] TOC, also known as total organic carbon, is a measure of the total amount of organic matter in water, expressed as carbon content. TOC can be used as an indicator to evaluate organic pollution in water quality and is widely used in the field of drinking water quality testing.

[0003] The relevant TOC analyzer includes a housing, a high-temperature combustion tube, a low-temperature combustion tube, and a non-dispersive infrared detector. The high-temperature combustion tube, low-temperature combustion tube, and non-dispersive infrared detector are installed inside the housing. The housing is equipped with a water inlet pipe that draws water samples into the device. The water samples, along with purified oxygen, are introduced into the high-temperature combustion tube and the low-temperature combustion tube, respectively. The water samples in the high-temperature combustion tube are heated to 900 degrees Celsius under the action of a catalyst, and the organic matter in the water samples is converted into carbon dioxide. The water samples in the low-temperature combustion tube are acidified, and the inorganic carbonates in the water decompose into carbon dioxide. The gases generated in the high-temperature combustion tube and the low-temperature combustion tube are respectively passed into the non-dispersive infrared detector, thereby detecting the amount of total carbon and inorganic carbon in the water samples, and finally obtaining the amount of organic carbon in the water samples.

[0004] The aforementioned technical solutions have the following drawbacks: during the experiment, personnel need to manually place water samples into the TOC analyzer. When there are multiple sources of drinking water to be tested and online testing is required, personnel need to frequently prepare water samples and place them into the TOC analyzer, resulting in low online testing efficiency. Summary of the Invention

[0005] To facilitate online testing of various drinking water products, this application provides a device and method for determining total organic carbon in drinking water.

[0006] The device for determining total organic carbon in drinking water provided in this application adopts the following technical solution:

[0007] A device for determining total organic carbon in drinking water includes a TOC analyzer, a connecting mechanism, a displacement mechanism, and a hose. The TOC analyzer has an inlet pipe installed inside, which is vertically positioned and connected to the TOC analyzer at its upper end. The displacement mechanism is installed on the lower side of the inlet pipe. The connecting mechanism includes multiple connecting pipes and a base. The base is installed on the displacement mechanism, and the multiple connecting pipes pass through and are connected to the base. The displacement mechanism is used to move the base horizontally and vertically. The connecting pipes are used to be fitted onto the inlet pipe, and a hose is connected to the bottom of each connecting pipe.

[0008] By adopting the above technical solution, a displacement mechanism is installed below the water inlet pipe. This mechanism can drive the base and connecting pipe to move horizontally and vertically below the water inlet pipe, allowing different connecting pipes to move below the water inlet pipe and be fitted onto it. This enables multiple hoses to be connected to the water inlet pipe. By connecting the hoses to different pipes, drinking water from various sources can enter the TOC analyzer for testing. One TOC analyzer can test drinking water from multiple pipes with short intervals between tests, providing convenient online testing for various types of drinking water.

[0009] Optionally, a sleeve is rotatably connected to the water inlet pipe, the sleeve is coaxially connected to the water inlet pipe, the inner wall of the sleeve is provided with internal threads, the outer wall of the connecting pipe is provided with external threads, the sleeve is threadedly connected to the connecting pipe, the base is provided with multiple mounting holes, each mounting hole is provided with a connecting pipe, the inner wall of the mounting hole is provided with a locking block, the outer wall of the connecting pipe is provided with a sliding groove, the length direction of the sliding groove is parallel to the length direction of the connecting pipe, and the locking block is locked in the sliding groove.

[0010] By adopting the above technical solution, a sleeve is installed on the water inlet pipe, allowing the sleeve to rotate on the water inlet pipe. The displacement mechanism can move the connecting pipe to the bottom of the sleeve and abut against the end of the sleeve. At this time, the sleeve rotates, making the sleeve and the connecting pipe threadedly connected. The locking block plays a guiding role, allowing the connecting pipe to slide vertically on the base, so that the connecting pipe can be connected to the water inlet pipe through the rotation of the sleeve.

[0011] Optionally, the connecting pipe is provided with a convex circle, which is used to lock onto the upper surface of the base, and a rubber ring is provided on the convex circle, which is used to abut against the lower end face of the sleeve.

[0012] By adopting the above technical solution, a convex circle is set on the connecting pipe, and the diameter of the convex circle is larger than the diameter of the mounting hole. This allows the connecting pipe to be secured to the base through the convex circle. When the sleeve is threadedly connected to the connecting pipe, the convex circle can move upward with the connecting pipe, thereby causing the rubber ring to abut against the end face of the sleeve and deform, thus sealing the gap between the sleeve and the connecting pipe.

[0013] Optionally, the TOC measuring instrument is equipped with a motor, the output shaft of which is connected to a drive gear, and a driven gear is fitted on a sleeve, with the driven gear meshing with the drive gear.

[0014] By adopting the above technical solution, by setting a driven gear on the sleeve and a driving gear on the motor, the motor can drive the sleeve to rotate automatically, thereby enabling the sleeve to automatically connect or disconnect from the connecting pipe, which improves the detection efficiency.

[0015] Optionally, the displacement mechanism includes a base, a lifting assembly, a slide, and a reciprocating assembly. The slide is slidably connected below the water inlet pipe, the reciprocating assembly is connected to the slide and is used to drive the slide to slide horizontally, the lifting assembly is installed on the slide, the base is connected to the lifting assembly, the base is installed on the base and the lifting assembly is used to drive the base to move vertically back and forth.

[0016] By adopting the above technical solution, and by setting a displacement mechanism below the connecting mechanism, the lifting component and the reciprocating component can drive the base to move in the vertical and horizontal directions respectively, thereby achieving the effect of moving the base. The connecting pipes at different positions on the base can be moved to the bottom of the water inlet pipe and connected to the water inlet pipe.

[0017] Optionally, the base is provided with a driving component, which is mounted on the bottom platform. The driving component is used to drive the base to rotate, and multiple mounting holes are equally spaced on the base along the center of the driving component.

[0018] By adopting the above technical solution, by setting a driving component on the base, the driving component can drive the base to rotate. When the connecting pipe is inserted into the mounting hole, the distance between each connecting pipe and the driving component is the same. By rotating the base, the driving component can make different connecting pipes located below the water inlet pipe.

[0019] Optionally, the base is set as a semi-circle, with two bases on the bottom platform, and each base is equipped with a connecting pipe.

[0020] By adopting the above technical solution, by setting connecting pipes on two semi-circular bases, the displacement mechanism can move the bases and position both bases below the water inlet pipe. The drive unit can move each connecting pipe on the base to below the water inlet pipe by rotating the base ninety degrees. The displacement of the base is small when moving the connecting pipe, thereby reducing the probability of the hose getting tangled on the drive unit.

[0021] A method for determining total organic carbon in drinking water using an apparatus includes the following steps:

[0022] S1: Connect the hoses to different pipes so that drinking water from different sources can flow through the hoses to a single connecting pipe;

[0023] S2: By controlling the displacement mechanism, different connecting pipes can be moved to the bottom of the water inlet pipe and abut against the sleeve;

[0024] S3: The sleeve rotates to make the connecting pipe threadedly connected to the sleeve, and the connecting pipe slides vertically relative to the base;

[0025] S4: The connecting pipe is moved up until it is fitted onto the inlet pipe. Drinking water enters the inlet pipe through the hose and connecting pipe, and the TOC meter performs water quality testing.

[0026] By adopting the above technical solution, and by setting a connecting mechanism in the TOC meter, the displacement mechanism can move the connecting mechanism, thereby allowing different connecting pipes to move to the bottom of the water inlet pipe. The displacement mechanism drives the connecting pipe to move upward and abut against the sleeve. At this time, the sleeve rotates to connect with the connecting pipe threadedly, thereby allowing the connecting pipe to move back and forth in the vertical direction, so that the connecting pipe can be automatically fitted onto the water inlet pipe. The step of replacing the connecting pipe takes less time, and a single TOC meter can monitor drinking water from multiple sources.

[0027] In summary, the beneficial technical effects of this application are as follows:

[0028] 1. By setting a connecting mechanism inside the TOC analyzer and a displacement mechanism below the connecting mechanism, the displacement mechanism can drive the base to move, thereby allowing multiple connecting pipes on the base to move to the bottom of the water inlet pipe and connect to the water inlet pipe. This achieves the effect of automatically connecting the connecting pipes to the water inlet pipe. The connecting pipes supply water through a flexible hose, enabling one TOC analyzer to sequentially test multiple types of drinking water. The time between each test is short, making it convenient for users to perform online testing of multiple types of drinking water.

[0029] 2. By installing a sleeve on the water inlet pipe and opening an internal thread in the sleeve, the connecting pipe can be connected to the sleeve through the thread. When the motor drives the sleeve to rotate, the connecting pipe can automatically connect to the sleeve, improving the sealing performance between the connecting pipe and the sleeve.

[0030] 3. By setting two semi-circular bases below the water inlet pipe, multiple connecting pipes can be installed on each base. The bases can be rotated to position different connecting pipes below the water inlet pipe. The rotation range of the bases is small, which can reduce the chance of hoses getting tangled on the drive components. Attached Figure Description

[0039] The present application will be further described in detail below with reference to the accompanying drawings.

[0040] This application discloses an apparatus for determining total organic carbon in drinking water, referring to... Figure 1 and Figure 2 It includes a TOC measuring instrument 1, a connecting mechanism 2, a displacement mechanism 3 and multiple hoses 4. The TOC measuring instrument 1 is equipped with a water inlet pipe 11, which is vertically arranged. The upper end of the water inlet pipe 11 is connected to the TOC measuring instrument 1, and the connecting mechanism 2 is located below the water inlet pipe 11.

[0041] Reference Figure 3 and Figure 4 The connecting mechanism 2 includes a sleeve 21, multiple connecting pipes 22, and two bases 23. The two bases 23 are mounted on the displacement mechanism 3 and are horizontally positioned. Multiple connecting pipes 22 are installed on each base 23. The sleeve 21 is fitted onto the inlet pipe 11. Flexible hoses 4 are made of an elastic material. One end of each hose 4 is connected to the lower end of a connecting pipe 22, and the other end is connected to a different pipe. A water valve is installed on the pipe to control the flow of water into the hose 4. The displacement mechanism 3 can move the connecting pipes 22 on the base 23, positioning them below and coaxially with the inlet pipe 11. By raising and lowering the connecting mechanism 2, the displacement mechanism 3 allows multiple connecting pipes 22 to connect to the inlet pipe 11. The drinking water to be tested can enter the inlet pipe 11 through the hoses 4 and connecting pipes 22, enabling a TOC analyzer 1 to automatically test drinking water from multiple sources.

[0042] Reference Figure 5 and Figure 6The sleeve 21 is rotatably connected to the water inlet pipe 11, with the lower end of the water inlet pipe 11 located inside the sleeve 21. The inner wall of the sleeve 21 has internal threads, and the outer wall of the connecting pipe 22 has external threads. Multiple sliding grooves 222 are formed on the outer wall of the connecting pipe 22, with the length of the grooves 222 parallel to the length of the connecting pipe 22. Multiple mounting holes 231 are formed on the base 23; these holes are through holes, and each connecting pipe 22 is inserted into one mounting hole 231. A locking block 232 is connected to the inner wall of the mounting hole 231, and the locking block 232 is inserted into the sliding groove 222, allowing the connecting pipe 22 to slide vertically on the base 23. A convex circle 221 is coaxially connected to the connecting pipe 22, and the convex circle 221 is used to lock onto the upper surface of the base 23. A rubber ring is installed on the upper surface of the convex circle 221, and the rubber ring abuts against the lower end face of the sleeve 21.

[0043] Reference Figure 3 and Figure 4 When the displacement mechanism 3 drives the connecting pipe 22 to coaxially abut against the lower side of the sleeve 21, the sleeve 21 can connect with the connecting pipe 22 by rotation. When the sleeve 21 rotates, the internal thread of the sleeve 21 engages with the external thread of the connecting pipe 22. The connecting pipe 22 rises on the base 23 under the drive of the thread, thereby allowing the connecting pipe 22 to be sleeved outside the water inlet pipe 11, so that the connecting pipe 22 and the water inlet pipe 11 are sealed together. A rubber ring can be provided on the top surface of the connecting pipe 22, and the rubber ring can abut against the bottom surface of the sleeve 21. The convex circle 221 can move upward with the connecting pipe 22 and abut against the lower end face of the sleeve 21. At this time, the rubber ring deforms and seals the gap between the sleeve 21 and the connecting pipe 22, improving the sealing effect.

[0044] Reference Figure 3 A driven gear 211 is provided on the sleeve 21, and the driven gear 211 is coaxially sleeved on the outside of the sleeve 21. A motor 213 is provided inside the TOC measuring instrument 1, and the housing of the motor 213 is fixedly installed. A driving gear 212 is coaxially connected to the output shaft of the motor 213, and the driving gear 212 meshes with the driven gear 211. The motor 213 can drive the sleeve 21 to rotate in both directions, so that the connecting pipe 22 can be automatically connected to the water inlet pipe 11.

[0045] Reference Figure 4 The displacement mechanism 3 includes a base platform 31, a lifting assembly 32, a slide table 33, and a reciprocating assembly 34. The slide table 33 is slidably connected inside the TOC measuring instrument 1 and is located below the water inlet pipe 11. The lifting assembly 32 can be an electric push rod or a hydraulic cylinder, and is vertically mounted on the slide table 33. The base platform 31 is fixed to the top of the lifting assembly 32. The reciprocating assembly 34 can be an electric push rod or a hydraulic cylinder, and is mounted inside the TOC measuring instrument 1 and connected to the slide table 33. The lifting assembly 32 drives the base platform 31 to move vertically, and the reciprocating assembly 34 drives the base platform 31 to move horizontally via the slide table 33.

[0046] Reference Figure 5 , Figure 6 and Figure 7 The base 23 is designed as a semi-circular plate structure, with multiple mounting holes 231 evenly spaced along the circumference of the base 23. The distance from each mounting hole 231 to the center of the semi-circular plate formed by the base 23 is the same. Each base 23 is equipped with a drive component 24, which can be a motor. The motor housing is fixed on the base 31, and the motor output shaft is connected to the center of the base 23. The motor can drive the base 23 to rotate on the base 31, thereby ensuring that the connecting pipes 22 in different mounting holes 231 are all located below the water inlet pipe 11. By dividing the circular base 23 into two semi-circular bases 23, the turning angle of each base 23 is smaller, and the length of the hose 4 below each connecting pipe 22 is reduced, achieving a simplified structure and reducing the probability of the hose 4 getting tangled on the drive component 24.

[0047] The implementation principle of this application embodiment is as follows: By setting a connecting mechanism 2 below the water inlet pipe 11, a hose 4 is connected to each of the multiple connecting pipes 22. By connecting different connecting pipes 22 to the water inlet pipe 11, drinking water from multiple sources can flow into the TOC analyzer 1 for testing. By installing a sleeve 21 over the water inlet pipe 11, the sleeve 21 is rotated by a motor 213, thereby enabling the sleeve 21 to be threadedly connected to the connecting pipe 22, reducing the probability of water overflowing between the sleeve 21 and the connecting pipe 22, and improving the sealing performance of the connection between the connecting pipe 22 and the water inlet pipe 11. By installing multiple connecting pipes 22 on two semi-circular bases 23, when different connecting pipes 22 are connected to the water inlet pipe 11, the base 23 only needs to rotate a maximum of ninety degrees, thereby reducing the length of the hose 4 and simplifying the structure.

[0048] This application discloses a method for determining total organic carbon in drinking water using an apparatus, comprising the following steps:

[0049] S1: Connect the hose 4 to different pipes so that drinking water from different sources can flow through the hose 4 to a connecting pipe 22;

[0050] S2: By controlling the displacement mechanism 3, different connecting pipes 22 can be moved to the bottom of the water inlet pipe 11 and abut against the sleeve 21;

[0051] S3: The sleeve 21 rotates, so that the connecting pipe 22 is threadedly connected to the sleeve 21, and the connecting pipe 22 slides vertically relative to the base 23;

[0052] S4: The connecting pipe 22 moves upward until it is fitted onto the water inlet pipe 11. Drinking water enters the water inlet pipe 11 through the hose 4 and the connecting pipe 22. The TOC meter 1 performs water quality testing.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
