Description

Technical Field

[0001] The present invention belongs to the technical field of sewage collection, and specifically refers to a sewage treatment laboratory sampling mechanism. Background Technique

[0002] With the development of technology, environmental pollution is an increasingly serious problem. Among them, sewage treatment is the top priority of many environmental problems. Sewage includes industrial sewage and domestic sewage. If sewage is directly discharged without being completely purified, it will re-enter the earth's water cycle system. In addition to damaging the ecological environment, sewage will also enter the human body and affect human health. The components of sewage are different. In order to better treat sewage, it is usually necessary to collect samples of sewage at different locations and then take them to the laboratory for analysis and experiments to find the most effective treatment method.

[0003] However, the following problems will be faced during the sewage collection process: impurities such as suspended solids, fibers, and sediment in the sewage are likely to block the sampling head filter screen, pump impeller, and pipeline, resulting in the interruption of sampling; mostly relying on external power to drive the blockage removal mechanism increases the cost and maintenance difficulty; traditional quantitative devices mostly use electronic valves or sensors for control, which have problems such as electromagnetic interference and program delay, and are prone to errors under complex working conditions, making it difficult to meet the strict requirements of national standards for the accuracy of sampling volume. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a sewage treatment laboratory sampling mechanism, which adopts a dynamic anti-blocking technology, realizes the synergistic effect of rotary centrifugal filtration and elastic adaptive blockage removal through fluid kinetic energy self-driving, and combines a buoyancy quantitative feedback mechanism to achieve high-efficiency anti-blocking, precise quantification, and low-energy consumption sampling, significantly improving the representativeness and collection reliability of sewage samples.

[0005] In order to achieve the above functions, the technical solution adopted by the present invention is as follows: a sewage treatment test collection mechanism, including a collection head, a pump body and a collection frame, a collection tube is connected between the collection head and the pump body, a delivery tube is connected between the pump body and the collection frame, a quantitative collection mechanism is provided on the collection frame, which can quantitatively store the collected sewage, a filtering and anti-blocking mechanism is provided in the collection head to ensure a smooth collection process and avoid pipeline blockage, the filtering and anti-blocking mechanism can make the sewage entering the collection tube more uniform, and avoid the collected water sample from being unable to represent the true nature of the sewage due to impurity deposition or stratification; the filtering and anti-blocking mechanism includes a filter screen plate, a force-assisted dirt-removing component and an elastic force-unblocking component, the filter screen plate is rotatably arranged at the bottom port of the collection head, the force-assisted dirt-removing component The force-assisted dirt-rejecting component is arranged in the collection head, and the elastic force unblocking component is arranged in the collection head. The force-assisted dirt-rejecting component is transmission-connected with the elastic force unblocking component, and the elastic force unblocking component is connected with the filter screen. The filter screen dynamically intercepts impurities, and the force-assisted dirt-rejecting component converts the kinetic energy of water into the elastic force unblocking component and the filter screen to rotate. The rotation generates centrifugal force, which throws the impurities away from the filter screen, reducing the amount of impurity accumulation on the filter screen surface. When the impurities on the filter screen surface accumulate to a certain extent, the resetting elastic force of the elastic force unblocking component is greater than the impact force of the water flow, thereby stretching and unblocking the filter screen, forcing the impurities stuck in the mesh to fall off. This not only improves the reliability and efficiency of sewage treatment testing and collection, but also reduces energy consumption and maintenance costs through adaptive fluid dynamic design.

[0006] As a preferred technical solution of the present invention, the force-assisted sewage rejection component includes a protective box, a rotating shaft and an impeller. The protective box is fixedly installed in the collection head, and the two ends of the rotating shaft are rotatably arranged to penetrate the opposite side walls of the protective box. The impeller is rotatably arranged on the outer side wall of the protective box and fixedly sleeved on the rotating shaft. When the water flow hits the impeller, the impeller converts the kinetic energy of the water into rotational kinetic energy, and drives the component to operate with the energy of the sewage flow. No additional power source is required, which saves energy and reduces the complexity and cost of the equipment.

[0007] As a preferred technical solution of the present invention, the elastic unblocking assembly includes a piston cylinder, a unblocking plate and a unblocking rod. The top end of the piston cylinder is transmission-connected to the rotating shaft, a piston rod is slidingly arranged in the piston cylinder, the piston rod slides through the bottom wall of the piston cylinder, a spring is connected between the top wall of the piston rod and the top wall of the piston cylinder, the unblocking plate is fixed at the bottom end of the piston rod, the unblocking rod is fixed under the unblocking plate and is evenly arranged, and the unblocking rod under the unblocking plate is used to continuously clear the blockage on the filter screen by using centrifugal force or other periodic forces and the elastic potential energy of the spring in the piston cylinder, thereby ensuring the continuity and stability of the filtration.

[0008] As a preferred technical solution of the present invention, the filter screen plate is fixedly connected to the piston cylinder. The filter screen plate is evenly provided with filter holes, and the filter holes are arranged in one-to-one correspondence with the through-blocking rods. When the piston cylinder rotates, it will drive the filter screen plate to rotate through the connecting rod. The rotation of the filter screen plate enables the sewage to pass through the filter holes more evenly, and the rotation generates a centrifugal force to throw the impurities away from the filter screen plate, improving the filtration efficiency.

[0009] As a preferred technical solution of the present invention, the quantitative collection mechanism includes a storage tank and a floating rod. The storage tanks are installed on the collection rack in a plurality of groups in a circular array. The bottom end of the floating rod slides through the top wall of the storage tank. A shunt pipe is connected between the storage tank and the delivery pipe. Sewage enters the storage tank through the delivery pipe and the shunt pipe. As the liquid level rises, the buoyancy ball drives the floating rod to move upward under the action of buoyancy.

[0010] As a preferred technical solution of the present invention, a multi-way reversing valve is provided on the delivery pipe, and a button is provided under the multi-way reversing valve. A plurality of groups of buttons are provided and are correspondingly arranged with the floating rods. The multi-way reversing valve is installed on the delivery pipe and is responsible for switching the diversion direction of the sewage. Each storage tank corresponds to a button, and the button is aligned with the top end of the floating rod. When the sewage is injected to a set volume, the buoyancy ball rises to a preset height, and the top end of the floating rod triggers the button of the multi-way reversing valve, thereby switching the diversion path, stopping the injection of liquid into the current storage tank, and turning to the next storage tank. Through mechanical buoyancy control, unattended automatic sampling is realized, which is especially suitable for scenarios that require long-term monitoring such as the wild and industrial wastewater, reducing labor costs while improving data accuracy.

[0011] Compared with the prior art, the present invention adopts the above structure to achieve the following beneficial effects: 1. Through the linkage of the impurity-throwing component by leveraging force and the elastic through-blocking component, the impeller in the impurity-throwing component by leveraging force rotates under the impact of water flow, drives the piston cylinder to rotate through gear reversal. Due to the centrifugal force or other periodic forces and the elastic potential energy of the spring, the piston rod is pushed to move up and down, so that the thorns on the through-blocking rod dredge the filter screen plate. As the sewage flows, the impeller continuously rotates, and the clogging removal action will also be carried out periodically, realizing automatic clogging removal, effectively preventing the filter screen plate from being blocked, and ensuring the smooth progress of sewage collection; 2. Through the linkage of the impurity-throwing component by leveraging force and the filter screen plate, the impurity-throwing component by leveraging force drives the filter screen plate to rotate through the connecting rod. When the sewage flows through the rotating filter screen plate, the impurities will be intercepted on the surface of the filter screen. At the same time, the centrifugal force generated by the rotation will throw out some impurities that are not firmly attached, realizing the preliminary separation of impurities. This dynamic filtration method avoids the excessive accumulation of impurities in a local area of the filter screen, makes the filtration more uniform, improves the filtration efficiency, and the automatic rotation and impurity separation functions of the filter screen plate reduce the frequency and workload of manual cleaning of the filter screen; 3. Through the linkage of the elastic blockage unclogging component and the filter screen plate, when collecting sewage, the impact force of the water flow on the blockage unclogging plate will compress the spring in the piston cylinder. When the impurities on the surface of the filter screen plate accumulate to a certain extent, the reset elastic force of the elastic blockage unclogging component is greater than the water flow impact force, so as to elongate and unclog the filter screen plate, forcing the impurities stuck in the mesh holes to fall off. The accurate blockage unclogging method can ensure that each filter hole can be effectively cleaned, avoiding the influence on the overall filtration effect due to local blockage; 4. Through mechanical buoyancy control, unattended automatic sampling is realized. When a certain storage tank in the quantitative collection mechanism reaches the set quantitative volume, the multi-way reversing valve will switch to the next storage tank to continue collecting sewage. During the process of changing the tank, the filter anti-blocking mechanism continues to work, ensuring the continuity of sewage collection. Description of the Drawings

[0014] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] like Figures 1-6 As shown, a sewage treatment test collection mechanism provided by the present invention comprises a collection head 1, a pump body 2 and a collection frame 3, a collection tube 4 is connected between the collection head 1 and the pump body 2, a delivery tube 5 is connected between the pump body 2 and the collection frame 3, a quantitative collection mechanism 6 is provided on the collection frame 3, which can quantitatively store the collected sewage, a filtering and anti-blocking mechanism 7 is provided in the collection head 1 to ensure a smooth collection process and avoid pipeline blockage, the filtering and anti-blocking mechanism 7 can make the sewage entering the collection tube 4 more uniform, and avoid the collected water sample from being unable to represent the true nature of the sewage due to impurity deposition or stratification; the filtering and anti-blocking mechanism 7 comprises a filter screen plate 71, a force-assisted dirt-removing component 72 and an elastic force unblocking component 73, the filter screen plate 71 is rotatably arranged at the bottom port of the collection head 1, the filter screen plate 71 is evenly arranged with filter holes 712, the force-assisted dirt-removing component 72 is provided in the collection head 1, and the elastic force unblocking component 73 is provided. The force-clearing and blocking component 73 is arranged in the collection head 1, and the force-clearing and blocking component 72 is transmission-connected with the elastic-clearing and blocking component 73, which is connected to the filter screen 71. The filter screen 71 dynamically intercepts impurities, and the force-clearing and blocking component 72 converts the kinetic energy of water into power, thereby driving the elastic-clearing and blocking component 73 and the filter screen 71 to rotate. The rotation generates centrifugal force, which throws impurities away from the filter screen 71, reducing the amount of impurity accumulation on the filter screen surface. When the impurities on the surface of the filter screen 71 accumulate to a certain extent, the resetting elastic force of the elastic-clearing and blocking component 73 is greater than the impact force of the water flow, thereby stretching and blocking the filter screen 71, forcing the impurities stuck in the mesh to fall off, thereby realizing the full-process anti-blocking of "interception, stripping and breaking", which not only improves the reliability and efficiency of sewage treatment testing and collection, but also reduces energy consumption and maintenance costs through adaptive fluid dynamic design.

[0016] like Figures 1-4As shown in the figure, the sewage flinging component 72 includes a protective box 721, a rotating shaft 722 and an impeller 723. The protective box 721 is fixedly installed in the collection head 1. Both ends of the rotating shaft 722 rotatably penetrate through the opposite side walls of the protective box 721. The impeller 723 is rotatably arranged on the outer side wall of the protective box 721 and fixedly sleeved on the rotating shaft 722. A first bevel gear 724 and a second bevel gear 725 are arranged in the protective box 721. The first bevel gear 724 is fixedly sleeved on the rotating shaft 722. The second bevel gear 725 is arranged on the inner bottom wall of the protective box 721. The second bevel gear 725 is meshed with the first bevel gear 724. When the water flow impacts on the impeller 723, it drives the impeller 723 to rotate. The impeller 723 drives the rotating shaft 722 to rotate accordingly. The rotation of the rotating shaft 722 drives the second bevel gear 725 to rotate through the first bevel gear 724, leveraging the energy of the sewage flow to drive the component operation without an additional power source, which not only saves energy but also reduces the complexity and cost of the equipment.

[0017] As Figures 2-6 shown in the figure, the elastic plugging and unplugging component 73 includes a piston cylinder 731, a plugging and unplugging plate 732 and a plugging and unplugging rod 733. The top end of the piston cylinder 731 rotatably penetrates through the protective box 721 and is connected to the second bevel gear 725. A connecting rod 711 is fixedly connected between the filter screen plate 71 and the piston cylinder 731. A piston rod 734 is slidably arranged in the piston cylinder 731. The piston rod 734 slidably penetrates through the bottom wall of the piston cylinder 731. A spring 735 is connected between the top wall of the piston rod 734 and the inner top wall of the piston cylinder 731. The plugging and unplugging plate 732 is fixedly arranged at the bottom end of the piston rod 734. The plugging and unplugging rods 733 are fixedly arranged under the plugging and unplugging plate 732 and are evenly distributed. Multiple groups of barbs 736 are arranged in an annular array at the bottom end of the plugging and unplugging rods 733. The filter holes 712 correspond to the plugging and unplugging rods 733 one by one. When the piston cylinder 731 rotates, it drives the filter screen plate 71 to rotate through the connecting rod 711. The rotation of the filter screen plate 71 enables the sewage to pass through the filter holes 712 more evenly, and the rotation generates centrifugal force to fling the impurities away from the filter screen plate 71, improving the filtering efficiency. When collecting sewage, the impact force of the water flow on the plugging and unplugging plate 732 compresses the spring 735. When the impurities on the surface of the filter screen plate 71 accumulate to a certain extent, the restoring elastic force of the spring 735 is greater than the water flow impact force, thereby elongating and unplugging the filter screen plate 71, forcing the impurities stuck in the mesh holes to fall off. Moreover, when the second bevel gear 725 rotates, it drives the connected piston cylinder 731 to rotate. When the piston cylinder 731 rotates, due to centrifugal force or other periodic forces, the piston rod 734 slides up and down in the piston cylinder 731, and the spring 735 releases elastic potential energy simultaneously, enabling the plugging and unplugging rods 733 under the plugging and unplugging plate 732 to continuously dredge the blockages on the filter screen plate 71, ensuring the continuity and stability of the filtration.

[0018] As Figures 1-2As shown in the figure, the quantitative collection mechanism 6 includes a storage tank 61 and a floating rod 63. Multiple groups of storage tanks 61 are installed on the collection rack 3 in an annular array. A buoyancy ball 62 is arranged in the storage tank 61. The bottom end of the floating rod 63 slidably penetrates the top wall of the storage tank 61 and is connected to the buoyancy ball 62. A shunt pipe 64 is connected between the storage tank 61 and the conveying pipe 5. A multi-way reversing valve 65 is arranged on the conveying pipe 5. There is a button 66 under the multi-way reversing valve 65. Multiple groups of buttons 66 are provided and are correspondingly arranged in cooperation with the floating rod 63. The multi-way reversing valve 65 is installed on the conveying pipe 5 and is responsible for switching the shunt direction of the sewage. Each storage tank 61 corresponds to a button 66. The button 66 is aligned with the top end of the floating rod 63. The sewage enters the storage tank 61 through the conveying pipe 5 via the shunt pipe 64. As the liquid level rises, the buoyancy ball 62 drives the floating rod 63 to move upward under the action of buoyancy. When the sewage is injected to the set volume, the buoyancy ball 62 rises to the preset height, and the top end of the floating rod 63 triggers the button 66 of the multi-way reversing valve 65, thereby switching the shunt path, stopping injecting liquid into the current storage tank 61, and turning to the next storage tank 61. Through mechanical buoyancy control, unattended automatic sampling is realized, which is especially suitable for scenarios such as the field and industrial wastewater that require long-term monitoring, reducing labor costs while improving data accuracy.

[0019] During specific use, the collection head 1 is immersed in the sewage, and the pump body 2 is started. The sewage is sucked in through the collection pipe 4. The sewage passes through the filter screen plate 71, and the impurities are intercepted by the filter screen plate 71. The water flow impacts the impeller 723, driving the impeller 723 to rotate. The impeller 723 drives the rotating shaft 722 to rotate accordingly. The rotation of the rotating shaft 722 drives the bevel gear one 724 to drive the bevel gear two 725 to rotate. The bevel gear two 725 drives the piston cylinder 731 to rotate. The piston cylinder 731 drives the filter screen plate 71 to rotate through the connecting rod 711. The rotating filter screen plate 71 generates centrifugal force, throwing off the impurities attached to the filter screen plate 71. The rotation of the filter screen plate 71 enables the sewage to pass through the filter holes 712 more evenly. At the same time, due to centrifugal force or other periodic forces during the rotation of the piston cylinder 731, the piston rod 734 slides up and down in the piston cylinder 731, and the spring 735 releases elastic potential energy at the same time, enabling the blocking rod 733 under the blocking plate 732 to continuously dredge the blockages on the filter screen plate 71, ensuring the continuity and stability of filtration. When collecting sewage, the impact force of the water flow on the blocking plate 732 will compress the spring 735. When the impurities on the surface of the filter screen plate 71 accumulate to a certain extent, the reset elastic force of the spring 735 is greater than the water flow impact force, so as to elongate and dredge the filter screen plate 71, forcing the impurities stuck in the mesh holes to fall off. The filtered sewage enters the annular storage tank 61 through the delivery pipe 5 and the shunt pipe 64. When the sewage is injected to a set volume, the buoyancy ball 62 rises to a preset height, and the top of the floating rod 63 triggers the button 66 of the multi-path reversing valve 65, thereby switching the shunt path, stopping the liquid injection into the current storage tank 61, and turning to the next storage tank 61 to achieve continuous sewage sampling.

[0020] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the gist of the present invention, they shall fall within the protection scope of the present invention.
