Description

Technical Field

[0001] This invention relates to the field of wastewater sampling and testing, and in particular to a wastewater sampling and testing device for veterinary drug production. Background Technology

[0002] The production of veterinary drugs usually involves a lot of antibiotics, organic solvents and other components. This can lead to the residue of these components in the wastewater generated during the production process. In order to ensure the safety of discharge, this wastewater usually needs to be treated by purification and testing before it is discharged. The testing process usually involves sampling the wastewater.

[0003] Existing sampling equipment for wastewater testing typically involves designing a tributary within a water-flowing pipeline, with a sampling tube installed within this tributary. The sampling tube then performs the sampling within the tributary. Alternatively, an auxiliary tube can be inserted into the pipeline; the sampling tube is inserted into the auxiliary tube when sampling is needed, and after sampling, the auxiliary tube is closed, and the sampling tube is removed. However, in these designs, the entire sampling tube is submerged in the tributary, resulting in some wastewater residue remaining on the tube after sampling. This residue requires wiping by operators, and the used tissues must be disposed of properly. If not wiped, this residue may drip onto the surrounding environment, causing environmental impact. Wiping, on the other hand, incurs additional waste and requires separate disposal of the tissues, making the process cumbersome. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides the following technical solution:

[0005] A wastewater sampling and testing device for veterinary drug production includes: a connecting pipe and a sampler disposed below the connecting pipe.

[0006] Specifically, the lower end face of the connecting tube is integrally formed with a branch tube, the bottom of the branch tube is provided with an inner tube, the outer side of the inner tube is covered with a rotatable sealing mask, the contact surface between the inner tube and the sealing mask is provided with a through-hole, the corresponding part of the sealing mask is provided with a through-slot, the upper end face of the sampler is provided with a third insertion tube, the third insertion tube is inserted into the inside of the slot, and the inner tube rotates to close or open the outlet hole.

[0007] As an improvement to the above technical solution, a connecting ring is detachably provided on the side of the branch pipe away from the connecting pipe, and a positioning ring is integrally formed on the side of the connecting ring away from the branch pipe. The inner tube is disposed in a closed cavity formed by the positioning ring, the branch pipe and the connecting ring. An insertion tube is integrally formed on the end of the inner tube away from the branch pipe. The insertion tube fits against the surface of the sealing mask, and the liquid outlet is opened at the center of the insertion tube.

[0008] As an improvement to the above technical solution, a flange is integrally formed on the side of the branch pipe away from the connecting pipe, and a flange is integrally formed on the side of the connecting ring near the branch pipe. The flange and the flange are detachably fixed by bolts.

[0009] As an improvement to the above technical solution, the inner wall of the branch pipe is integrally formed with a limiting part 1, the end of the inner pipe away from the insertion tube 1 is attached to the limiting part 1, and a sealing ring is embedded in the contact surface between the limiting part 1 and the insertion tube 1.

[0010] As an improvement to the above technical solution, the outer wall of the connecting ring, the flange, and the upper end face of the positioning ring are separated to form a fastening part that opens to the outside. The upper end face of the sealing mask is open and covers the outside of the positioning ring. A fixing ring is provided on the inner side of the fastening part, and a screw hole penetrating into the interior of the sealing mask is provided on the surface of the fixing ring.

[0011] As an improvement to the above technical solution, an elastic element two is provided between the positioning ring and the inner wall of the sealing mask, a limiting ring is provided at the bottom of the sealing mask, the end of the insertion tube one is inserted into the inside of the limiting ring, an extension is detachably fixed to the outside of the limiting ring, and an elastic element one is provided between the positioning ring and the extension.

[0012] As an improvement to the above technical solution, the lower end face of the sealing mask is integrally formed with a second insertion tube, the slot passes through the second insertion tube, the upper end face of the sampler is provided with a sealing ring, the third insertion tube is disposed inside the sealing ring, and the inner wall of the sealing ring is attached to the outer wall of the second insertion tube.

[0013] As an improvement to the above technical solution, a number of rubber rings are embedded and fixed in the inner wall of the slot, and a number of sealing grooves are opened on the outer side of the insertion tube three, with the rubber rings nested on the outer side of the sealing grooves.

[0014] As an improvement to the above technical solution, the inner diameter of the groove of the insertion tube three is larger than the diameter of the liquid outlet hole.

[0015] As an improvement to the above technical solution, the sampler has an internal cavity that is connected to the insertion tube. The upper end face of the sampler is provided with an integrally formed exhaust pipe that is connected to the internal cavity. The exhaust pipe has two sets of limiting parts 2 symmetrically arranged inside. The surface of the limiting parts 2 is provided with through-holes. A ball is provided between the two limiting parts 2. The outer ring of the ball is integrally formed with a baffle. The shape of the ball is the same as the groove of the air hole.

[0016] The beneficial effects of this invention are:

[0017] By using a rotatable sealing mask and its inner tube, a rotatable outlet is formed. Rotation creates a misaligned seal. When sampling is needed, a fixed sampler is used to take samples. After sampling, the sampler is rotated back to its initial closed state and then removed. This avoids leakage problems that occur during conventional sampling and prevents residual wastewater from impacting the surrounding environment. Similarly, a tributary sampling method is used, but the difference lies in the ability to control the opening and closing of the outlet during sampling, and the sampler itself does not need to be submerged in wastewater, thus avoiding residual leakage.

[0031] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0032] Existing sampling equipment for wastewater testing typically involves designing a tributary within a water-flowing pipeline, with a sampling tube installed within this tributary. The sampling tube then performs the sampling within the tributary. Alternatively, an auxiliary tube can be inserted into the pipeline; the sampling tube is inserted into the auxiliary tube when sampling is needed, and after sampling, the auxiliary tube is closed, and the sampling tube is removed. However, in these designs, the entire sampling tube is submerged in the tributary, resulting in some wastewater residue remaining on the tube after sampling. This residue requires wiping by operators, and the used tissues must be disposed of properly. If not wiped, this residue may drip onto the surrounding environment, causing environmental impact. Wiping, on the other hand, incurs additional waste and requires separate disposal of the tissues, making the process cumbersome.

[0033] To resolve the above issues, please refer to Figures 1 to 10 A wastewater sampling and testing device for veterinary drug production is provided, comprising: a connecting pipe 10 and a sampler 20 disposed below the connecting pipe 10.

[0034] Specifically, the lower end face of the connecting tube 10 is integrally formed with a branch tube 11, the bottom of the branch tube 11 is provided with an inner tube 13, the outer side of the inner tube 13 is covered with a rotatable sealing mask 14, the contact surface between the inner tube 13 and the sealing mask 14 is provided with a through-hole 132, the corresponding part of the sealing mask 14 is provided with a through-hole 145, the upper end face of the sampler 20 is provided with a third insertion tube 22, the third insertion tube 22 is inserted into the inside of the 145, and the inner tube 13 is rotated to close or open the outlet 132.

[0035] First, the connecting pipe 10 needs to be properly installed in the sewage delivery pipeline. When sewage flows through the inside of the connecting pipe 10, some sewage will enter the inside of the branch pipe 11. When the outlet hole 132 at the bottom is closed, the sewage inside the branch pipe 11 will continuously flow back. That is, the sewage that enters first will flow out with the sewage that enters later, thus constantly alternating to ensure that the sewage inside the branch pipe 11 is the most recently flowing in, thereby ensuring the accuracy of the sampling data.

[0036] When performing sampling, first insert the cannula 22 of the sampler 20 into the slot 145, and then rotate the sealing mask 14. The misalignment of the sealing mask 14 will cause the outlet hole 132 to intersect with the slot 145, and the intersecting part will be connected with the cannula 22. At this time, the sampling state is in progress. The time of intersection formation is controlled according to the required sampling quantity. Therefore, the sampler 20 is preferably made of transparent material to facilitate observation of the total sampling quantity. After the sampling quantity is reached, rotate the sealing mask 14 to drive the outlet hole 132 to misalign with the slot 145. When the two no longer intersect, the outlet state is sealed. Let it stand for a period of time to ensure that the sewage at the connection point enters the interior along the slot 145. Then, remove the sampler 20 to complete the sampling operation.

[0037] To facilitate the cleaning of subsequent structural components, it is also necessary to ensure the detachability of the inner tube 13 structure. Specifically, a connecting ring 12 is detachably provided on the end face of the branch pipe 11 away from the connecting pipe 10. A positioning ring 122 is integrally formed on the end face of the connecting ring 12 away from the branch pipe 11. The inner tube 13 is disposed in the closed cavity formed by the positioning ring 122, the branch pipe 11 and the connecting ring 12. An insertion tube 131 is integrally formed on the end of the inner tube 13 away from the branch pipe 11. The insertion tube 131 fits against the surface of the sealing mask 14, and the liquid outlet 132 is opened at the center of the insertion tube 131.

[0038] The inner pipe 13 is positioned and fixed by the cooperation between the connecting ring 12 and the branch pipe 11. Specifically, the fixing between the branch pipe 11 and the connecting ring 12 can adopt the following structure:

[0039] A flange 112 is integrally formed on the end face of the branch pipe 11 away from the connecting pipe 10, and a flange 121 is integrally formed on the end face of the connecting ring 12 near the branch pipe 11. The flange 112 and the flange 121 are detachably fixed by bolts.

[0040] A sealing ring can be embedded between flange 112 and flange 221 to enhance the sealing between structural components, while the connection through the flange structure ensures subsequent disassembly.

[0041] In the aforementioned scheme, the inner tube 13 is supported only on one side. If the entire tube structure is subjected to an external impact, the inner tube 13 may shake or become unstable. When the liquid is flowing normally inside, this shaking may cause sewage leakage. To avoid this problem, specifically, the inner wall of the branch pipe 11 is integrally formed with a limiting part 111. The end of the inner tube 13 away from the insertion tube 131 is attached to the limiting part 111. A sealing ring is embedded in the contact surface between the limiting part 111 and the insertion tube 131.

[0042] The limiting part 111 restricts the position of the other end of the inner tube 13. With the cooperation of the positioning ring 122 and the limiting part 111, a stable clamping of the position of the inner tube 13 is formed. A sealing ring is embedded between the limiting part 111 and the insertion tube 131 to form a reinforced sealing function of the structure. When the flange 112 and the flange 2 121 are tightened, the internal limiting part 111 and the positioning ring 122 clamp the inner tube 13 located in the middle and form a mechanical seal protection state at the connection with the sealing ring.

[0043] The aforementioned technical solution only restricts the structural improvement of the inner tube 13. The sealing mask 14 that works with it also needs to be modified according to its specific structure. In order to ensure that the structural components can be disassembled and installed normally, specifically, the outer wall of the connecting ring 12, the flange 121 and the upper end face of the positioning ring 122 are separated to form a fastening part 123 that opens to the outside. The upper end face of the sealing mask 14 is open and covers the outside of the positioning ring 122. A fixing ring 147 is provided on the inner side of the fastening part 123. The surface of the fixing ring 147 is provided with a screw hole that penetrates into the interior of the sealing mask 14.

[0044] By extending the length of the positioning ring 122, it is spaced apart from the flange 121 and the connecting ring 12 on the outer side to form a fastening part 123. Then, an independent fixing ring 147 is set inside the fastening part 123. The detachable installation design between the structural components is realized through the screw hole between the fixing ring 147 and the sealing mask 14. When disassembling, it is only necessary to unscrew the screw used to connect the fixing ring 147 and the sealing mask 14. In addition, the fixing ring 147 can be connected to the inner groove thread of the fastening part 123, thereby ensuring the stability of the overall structure after being fixed with the sealing mask 14.

[0045] In the aforementioned technical solution, there is no external force structure between the sealing mask 14 and the fixing ring 147. This means that the bolts for fixing the sealing mask 14 and the fixing ring 147 need to be inserted from the side and also need to cooperate with the positioning ring 122 to ensure the stability of the structure. This structural design is too cumbersome. To avoid this problem, specifically, an elastic element 144 is provided between the positioning ring 122 and the inner wall of the sealing mask 14. A limiting ring 141 is provided at the bottom of the sealing mask 14. The end of the insertion tube 131 is inserted into the inside of the limiting ring 141. An extension is detachably fixed to the outside of the limiting ring 141. An elastic element 143 is provided between the positioning ring 122 and the extension.

[0046] Elastic support is provided by elastic element 143 and elastic element 144. When the structural components are tightened, elastic element 143 is in a compressed state, while elastic element 144 is in a stretched state. Elastic element 143, in its compressed state, provides an outward rebound force, forming an internal elastic support structure to ensure the structural stability of the inner tube 13. Elastic element 144, in its stretched state, provides an inward squeezing force, ensuring that the sealing mask 14 is tightly pressed against the end face of the insertion tube 131, guaranteeing a tight connection between the structural components. Elastic elements 143 and 144 are typically spring-loaded and need to be replaced after a period of use to prevent a decrease in the spring stiffness coefficient, which could lead to a loose seal.

[0047] The extension portion on the outer side of the limiting ring 141 is typically a threaded ring. This ring is used to fit the limiting ring 141, ensuring the stability of the connection while providing support to the elastic element 144.

[0048] In the aforementioned technical solution, the connection distance between the sealing mask 14 and the insertion tube 22 is relatively narrow. In this case, there may be slight leakage of some sewage during the sampling process. To avoid this problem, the lower end face of the sealing mask 14 is integrally formed with the insertion tube 142, the slot 145 passes through the insertion tube 142, the upper end face of the sampler 20 is provided with a sealing ring 23, the insertion tube 22 is located inside the sealing ring 23, and the inner wall of the sealing ring 23 is attached to the outer wall of the insertion tube 142.

[0049] The cooperation between the insertion tube 22 and the sealing ring 23 forms a tubular connection and closure structure. This design can extend the connection length between structural components, allowing the entire insertion tube 322 to be inserted into the slot 145. With the increased flow channel and enhanced internal fit, there will be no leakage during sampling. To further ensure the sealing at the sampling position, several rubber rings 146 are embedded and fixed in the inner wall of the slot 145, and several sealing grooves 221 are opened on the outer side of the insertion tube 322. The rubber rings 146 are nested on the outer side of the sealing grooves 221.

[0050] By setting several rubber rings 146 on the inner wall to form a closed state for the inside of the insertion cannula 22, and cooperating with the sealing groove 221 on the outer side to form multiple buffered sealing states, the sealing of the sampling position is further enhanced.

[0051] In the aforementioned technical solution, since the contact between the insertion tube 22 and the liquid outlet 132 is a close fit, wear may occur during long-term use, resulting in liquid leakage at the connection gap between the insertion tube 22 and the liquid outlet 132. To avoid this problem, specifically, the inner diameter of the groove of the insertion tube 22 is larger than the diameter of the liquid outlet 132.

[0052] Under the overall downward gravity environment, the liquid flowing out of the insertion tube 22 will tend to fall, thus avoiding contact with the insertion tube 22. After sampling is completed, the whole thing needs to be left to stand for a period of time to ensure that all residual sewage enters the sampler 20 through the insertion tube 22.

[0053] During sampling, the increase in liquid will cause changes in internal air pressure. To ensure normal sampling function, specifically, the sampler 20 has an inner cavity 21, which is connected to the insertion tube 22. The upper end face of the sampler 20 is provided with an integrally formed exhaust pipe 24, which is connected to the inner cavity 21. The exhaust pipe 24 has two sets of limiting parts 25 symmetrically arranged inside. The surface of the limiting parts 25 has a through air hole 251. A ball 26 is provided between the two limiting parts 25. The outer ring of the ball 26 is integrally formed with a baffle 261. The ball 26 has the same groove shape as the air hole 251.

[0054] When sewage enters the inner cavity 21, the internal pressure increases, causing the ball 26 to float upwards due to the gas push. Since the liquid outlet speed at the liquid outlet 132 is relatively slow, the ball 26 will not directly hit the upper limiting part 25, but will remain suspended in the middle position to ensure that the airflow can overflow normally. The operator can control the time when the liquid flows out of the liquid outlet 132 according to the sampling needs. The scale can be marked on the surface of the sampler 20, and the sampling needs can be judged according to the position of the scale.

[0055] When an operator makes a mistake that results in an excessive sample volume, the baffle 261 will float on the surface of the liquid and rise with the liquid until it adheres to the surface of the upper limiting part 25 and seals the vent 251 in the middle of the upper limiting part 25. Since the vent 251 is sealed, the space inside it is also sealed simultaneously, preventing the air from being released and the liquid from being drained, thus forming a complete sealed state and preventing the liquid from overflowing from the exhaust pipe 24 due to operator error.

[0056] The above embodiments are merely illustrative of the technical solutions of the present invention and are not intended to limit it. Anyone skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
