A multifunctional and environmentally friendly experimental solid-liquid separation and detection device

Abstract

This invention provides a multifunctional environmentally friendly experimental solid-liquid separation and detection device, the structure of which includes: a base, a balance block, a vertical plate, a filter cylinder, a liquid collection component, and a collection component. The invention improves upon the vertical plate by using a pressure structure on the plate to align it with the filter cylinder on the same vertical line. When the rotating component of the pressure structure rotates, it drives the threaded rod to rotate in both directions, causing the sealing component to slide downwards or upwards in conjunction with the thread pattern. Simultaneously, after the sealing component enters the filter cylinder, the mutual contact of the inner walls and the downward pressure of the air force force the residual liquid on the solid inside to be pushed away, ensuring complete separation of the solid and liquid. This improves the accuracy of the solid-liquid separation detection device, avoids data errors caused by liquid residue, and further enhances the multifunctional use of the device by pressing downwards or directly squeezing the solid to force out residual liquid.

Description

Technical Field

[0001] This invention relates to the field of environmental protection experimental technology, and more specifically to a multifunctional environmental protection experimental solid-liquid separation and detection device. Background Technology

[0002] Solid-liquid separation in environmental protection experiments is the process of separating solid particles from liquid in a mixture. It can be achieved through methods such as filtration, natural sedimentation, and centrifugation to separate the solid and liquid. This allows the environmental liquid to be tested to be introduced into a specialized detection device, and then the solid and liquid are separated by the separation process. This separation improves the accuracy of data in distinguishing between dissolved and total amounts during environmental protection experiments. In summary, the inventors have found that existing solid-liquid separation detection devices have the following main defects: When current solid-liquid separation detection devices typically perform solid-liquid separation through filtration or natural sedimentation, after most of the liquid is transported downwards by centrifugal force, a small amount of liquid remains inside some solids, which is difficult to flow through centrifugal force. This easily leads to frequent incomplete separation, and ultimately, the solids will be affected by the inaccurate data due to the influence of these residual liquids. Summary of the Invention

[0003] The technical solution adopted by the present invention to achieve the technical objective is: a multifunctional environmentally friendly experimental solid-liquid separation and detection device, the structure of which includes: a base, a balance block, a vertical plate, a filter cylinder, a liquid collection component, and a collection component. The upper end of the base is parallel to the balance block, and the balance block determines the position of the filter cylinder and the liquid collection component through the vertical plate. The lower end of the liquid collection component is connected to the collection component.

[0004] As a further improvement of the present invention, the vertical plate is provided with a fixed end, the upper end of the fixed end is integrated with the lower end of the plate body, a slot is opened on the surface of the plate body, and a horizontal plate is connected above the surface of the plate body, with a pressing structure mounted at the center of the horizontal plate.

[0005] As a further improvement of the present invention, the compression structure is further provided with a positioning body, the center of which is connected to a rotating component and the center is penetrated by a threaded rod, the upper end of which is provided with a restraining disc and the lower end of which is connected to a sealing component.

[0006] As a further improvement of the present invention, the plate body is made perpendicular to the upper end of the balance block by the fixed end of the vertical plate, and then the horizontal plate of the plate body allows the compression structure to pass through vertically. The compression structure uses the rotating component to drive the threaded rod to rotate in both directions, while the sealing component is embedded in or removed from the filter cylinder for resetting.

[0007] As a further improvement of the present invention, the lower end of the base is connected to four support blocks, and the vertical plate on the balance block is equipped with a control panel to control the internal sensors of the filter cartridge and the liquid collection assembly. The collection assembly is installed on the balance block and is on the same vertical line as the liquid collection assembly.

[0008] As a further improvement of the present invention, an auxiliary block is connected to the center of the fixed end to help the plate body be vertically inserted into the balance block. The slot of the plate body is rectangular and is compatible with the plate carried by the liquid collection component. The horizontal plate and the pressure structure intersect each other.

[0009] As a further improvement of the present invention, the positioning body is installed at the upper and lower positions of the rotating assembly and the center position of both is penetrated by the threaded rod. The restraining disc and the threaded rod form a "T" shape, and the sealing assembly and the lower center point of the threaded rod overlap each other.

[0010] As a further improvement of the present invention, the positioning body is provided with a threaded groove, which passes through the center of the upper plate, the vertical sleeve and the lower plate. An extension tube is mounted at the center of the lower end of the lower plate, and a reinforcing block is mounted on the edge of the extension tube.

[0011] As a further improvement of the present invention, the threaded groove is opened in a vertical orientation and matches the threaded rod. The upper plate and the lower plate at the lower end of the vertical sleeve are set in a symmetrical orientation and form an "I" shape. The extension rod and the reinforcing block are inserted into the horizontal plate for vertical positioning and restrain the threaded rod.

[0012] As a further improvement of the present invention, the sealing assembly is further provided with a rust-proof block, the edge of which is covered by a silicone sleeve, and the silicone sleeve and the edge of the rust-proof block are equipped with locking bolts.

[0013] As a further improvement of the present invention, the rust-proof block and the silicone sleeve are circular in shape, and the edge of the silicone sleeve is connected to the rust-proof block by multiple locking bolts. The silicone sleeve is fitted to the inner wall of the filter cylinder.

[0014] As a further improvement of the present invention, the collecting component is provided with a slider, the upper end of the slider is connected to a slide plate, the slide plate covers the lower end of the collecting block, the edge of the collecting block is connected to a pull block, the upper end of the collecting block is connected to a disassembly block, the upper center of the disassembly block is connected to a rubber sleeve and a guide tube is mounted on the inner side.

[0015] As a further improvement of the present invention, the slider and the slide are perpendicular to each other and located at the lower end of the collecting block and embedded in the balance block. The upper end of the collecting block is engaged with the disassembly block by adsorption. The rubber sleeve of the disassembly block helps the guide tube to be embedded in the lower end of the liquid collection assembly and is reinforced by the rebound of the rubber block.

[0016] As a further improvement of the present invention, the disassembly block is also provided with a position plate, the upper end of which is connected to the lower edge of the adsorption block, and the upper end of the adsorption plate is connected to a pressing block. The pressing block has a slot on its edge and a vertical slot in its center.

[0017] As a further improvement of the present invention, the position plate has four pieces at the lower edge of the adsorption block and is attached to the inner wall of the collection block. The adsorption block is parallel to the upper surface of the collection block. The pressing block is solid and allows the liquid in the guide tube to flow downward through the central vertical groove.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, improved from a vertical plate, uses a pressing structure on the plate to align with the filter cylinder on the same vertical line. The rotating component of the pressing structure rotates, causing the threaded rod to rotate in both directions. This, combined with the thread pattern, drives the sealing component to slide downwards or upwards. Simultaneously, after the sealing component enters the filter cylinder, the internal walls adhere to each other, and the downward pressure creates airflow that forces residual liquid on the solid within, ensuring complete separation of the solid and liquid. This improves the accuracy of solid-liquid separation detection and avoids data errors caused by liquid residue. Furthermore, downward pressure or direct squeezing of the solid forces out residual liquid for separation, thus enhancing the multi-functionality of the device.

[0019] 2. The improved positioning body of this invention enhances the control accuracy of the rotating wheel of the rotating component by using the "I" shape formed by the vertical sleeve and the upper and lower plates, preventing deviation. Furthermore, the lower extension tube and reinforcing block effectively increase the contact area with the threaded rod, improving stability during rotation. Combined with the silicone sleeve of the sealing component, which can be firmly fixed by the locking bolt and the anti-rust block, a sealed space can be formed by the complete contact between the edge of the silicone sleeve and the inner wall of the filter cylinder. At the same time, the pressure generated when the threaded rod continues to push downward can further stabilize and force out the residual liquid in the solid, thus further improving the stability of solid-liquid separation.

[0020] 3. In this invention, the improved collection component allows the collection block to slide on the balance block by pulling the lower slide plate and slider of the collection block. At the same time, it forces the guide tube in the rubber sleeve to separate from the lower end of the liquid collection component. Therefore, after the test is completed, the liquid in the liquid collection component flows downward into the collection block. The separation effect facilitates disassembly. Furthermore, the pressing block of the disassembly block can be forcibly separated from the surface of the collection block through the hollow groove, opening the upper end of the collection block. This facilitates the cleaning of the internal liquid and prevents the difficulty in cleaning after the liquid has accumulated. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings: Example 1: Figures 1 to 5 As shown: This invention provides a multifunctional and environmentally friendly experimental solid-liquid separation and detection device. Its structure includes: a base 1, a balance block 2, a vertical plate 3, a filter cylinder 4, a liquid collection assembly 5, and a collection assembly 6. The upper end of the base 1 is parallel to the balance block 2, and the balance block 2 determines the position of the filter cylinder 4 and the liquid collection assembly 5 through the vertical plate 3. The lower end of the liquid collection assembly 5 is connected to the collection assembly 6.

[0030] The vertical plate 3 is provided with a fixed end 31. The upper end of the fixed end 31 is integrated with the lower end of the plate body 32. The surface of the plate body 32 has a slot 33. A horizontal plate 34 is also connected above the surface of the plate body 32. A pressure structure 35 is mounted at the center of the horizontal plate 34.

[0031] The compression structure 35 is further provided with a positioning body 351. The center of the positioning body 351 is connected to a rotating component 352 and the center is penetrated by a threaded rod 353. The upper end of the threaded rod 353 is provided with a restraining disc 354, and the lower end of the threaded rod 353 is also connected to a sealing component 355.

[0032] In this process, the plate 32 is perpendicular to the upper end of the balance block 2 by the fixed end 31 of the vertical plate 3, and then the horizontal plate 34 of the plate 32 allows the pressing structure 35 to pass through vertically. The pressing structure 35 uses the rotating component 352 to drive the threaded rod 353 to rotate in both directions, while the sealing component 355 is embedded in or removed from the filter cylinder 4 for resetting.

[0033] The base 1 has four support blocks connected to its lower end. The vertical plate 3 on the balance block 2 is equipped with a control panel to control the internal sensors of the filter cartridge 4 and the liquid collection assembly 5. The collection assembly 6 is installed on the balance block 2 and is on the same vertical line as the liquid collection assembly 5.

[0034] The fixed end 31 is connected to an auxiliary block at its center to help the plate 32 be inserted vertically into the balance block 2. The slot 33 of the plate 32 is rectangular and is compatible with the plate carried by the liquid collection component 5. The horizontal plate 34 and the pressure structure 35 intersect each other.

[0035] The positioning body 351 is installed at the upper and lower positions of the rotating component 352, and the center position of both is penetrated by the threaded rod 353. The restraining disc 354 and the threaded rod 353 form a "T" shape, and the sealing component 355 overlaps with the lower center point of the threaded rod 353.

[0036] The positioning body 351 is provided with a threaded groove 3511, which passes through the center of the upper plate 3512, the vertical sleeve 3513, and the lower plate 3514. An extension tube 3515 is mounted at the lower center of the lower plate 3514, and a reinforcing block 3516 is mounted on the edge of the extension tube 3515.

[0037] The threaded groove 3511 is opened vertically and matches the threaded rod 353. The upper plate 3512 and the lower plate 3514 at the lower end of the vertical sleeve 3513 are set symmetrically and form an "I" shape. The extension rod 3515, together with the reinforcing block 3516, is inserted into the horizontal plate 34 for vertical positioning and restrains the threaded rod 353.

[0038] The sealing component 355 is further provided with a rust-proof block 3551, the edge of which is covered by a silicone sleeve 3552, and the silicone sleeve 3552 and the edge of the rust-proof block 3551 are equipped with locking bolts 3553.

[0039] The rust-proof block 3551 and the silicone sleeve 3552 are circular in shape. The edge of the silicone sleeve 3552 is connected to the rust-proof block 3551 by multiple locking bolts 3553. The silicone sleeve 3552 is attached to the inner wall of the filter cylinder 4.

[0040] The specific functions and operation procedures of this embodiment are as follows: In this invention, the multifunctional environmental protection experimental solid-liquid separation and detection device uses the base 1 and the balance block 2 to determine the position of the vertical plate 3. After the vertical plate 3 determines the positions of the filter cylinder 4 and the liquid collection assembly 5, the solid to be tested is loaded into the filter cylinder 4, allowing it to directly contact the internal sensors and filter screen. Simultaneously, combined with centrifugal force and vertical orientation, it undergoes natural sedimentation, causing the separated liquid to enter the liquid collection assembly 5 and contact the sensors. Then, based on the cooperation of the internal sensors, the separated solid and liquid data can be detected, thus completing the solid-liquid separation and detection operation. Finally, when it is necessary to clean the liquid inside the liquid collection assembly 5, the switch can be turned on via the control panel mounted on the outside of the vertical plate 3, allowing the liquid inside the liquid collection assembly 5 to continue flowing downwards. When liquid is collected in the collection component 6, a rapid cleaning effect can be achieved. The vertical plate 32 is then connected to the balance block 2 via the lower fixed end 31. The slot 33 secures the insert plate carried by the filter cartridge 4 and the liquid collection component 5, ensuring they are parallel to the horizontal plate 34. This allows them to be aligned with the pressure structure 35 on the same vertical center line, ensuring the pressure structure 35 is perpendicular to the filter cartridge 4. When liquid remains in the solid, the positioning body 351 of the pressure structure 35 positions the rotating component 352 on the horizontal plate 34. The rotating component 352 uses an internal small drive motor to rotate the wheel, which in turn drives the threaded rod 353 to rotate in both directions. During these rotations, the threaded rod 353 carries the lower sealing component 35. 5. After entering the filter cylinder 4, the sealing component 355 adheres to the inner wall of the filter cylinder 4. The continued pushing of the threaded rod 353 creates a downward pressure, forcing out the liquid remaining on the solid through air compression. This improves the accuracy and integrity of solid-liquid separation, preventing inaccurate data due to residue. Furthermore, by forcing out the liquid remaining in the solid, the multi-functionality of the device is enhanced. During operation, the "I" shape formed by the upper plate 3512 of the positioning body 351, the vertical sleeve 3513, and the lower plate 3514 effectively restrains the position of the small drive motor and rotating wheel of the rotating component 352, preventing positional deviation. This improves the efficiency of the threaded groove 3511. The threaded rod 353 achieves stable rotation during movement. Furthermore, the extension tube 3515 at the lower end of the lower plate 3514, combined with the reinforcing block 3516, can be vertically installed inside the horizontal plate 34, increasing the contact length with the threaded rod 353. This indirectly improves the rotational stability of the threaded rod 353 and its threaded texture. Subsequently, the rust-proof block 3551 of the sealing assembly 355 can be fixed to the silicone sleeve 3552 via the edge locking bolt 3553. The silicone sleeve 3552, after covering the edge of the rust-proof block 3551, improves the airtightness of the seal against the inner wall of the filter cartridge 4. This effectively increases the airtight pressure inside the filter cartridge 4 when the threaded rod 353 is continuously pushed downwards, preventing the downward pressure caused by minor edge gaps.This further improves the intensity of solid-liquid separation and the stability of internal sensor detection.

[0041] Example 2: Figures 6 to 7 As shown: This invention provides a multifunctional and environmentally friendly experimental solid-liquid separation and detection device. Its structure includes a slider 61 provided in the collection component 6, a slide plate 62 connected to the upper end of the slider 61, the slide plate 62 covering the lower end of the collection block 63, a pull block 64 connected to the edge of the collection block 63, a disassembly block 65 connected to the upper end of the collection block 63, a rubber sleeve 66 connected to the center of the upper end of the disassembly block 65 and a guide tube 67 mounted on the inner side.

[0042] The slider 61 is perpendicular to the slide plate 62 and is located at the lower end of the collecting block 63 and embedded in the balance block 2. The upper end of the collecting block 63 is engaged with the disassembly block 65. The rubber sleeve 66 of the disassembly block 65 helps the guide tube 67 to be embedded in the lower end of the liquid collection assembly 5 and is reinforced by the rebound of the rubber block 66.

[0043] The disassembly block 65 is also provided with a position plate 651. The upper end of the position plate 651 is connected to the lower edge of the adsorption block 652. The upper end of the adsorption plate 652 is connected to a pressing block 653. The pressing block 653 has a hollow groove 654 on its edge and a vertical groove 655 in its center.

[0044] The position plate 651 has four pieces at the lower edge of the adsorption block 652 and is attached to the inner wall of the collection block 63. The adsorption block 652 is adsorbed parallel to the upper surface of the collection block 63. The pressing block 653 is solid and allows the liquid in the guide tube 67 to flow downward through the central vertical groove 655.

[0045] The specific functions and operation procedures of this embodiment are as follows: In this invention, the sliding plate 62 and slider 61 at the lower end of the collecting block 63 of the collecting component 6 are mounted on the surface of the balance block 2. Then, the edge pull block 64 of the collecting block 63 can be manually pulled laterally to force the rubber sleeve 66 and guide tube 67 on the disassembly block 65 to disengage from the lower end of the liquid collecting component 5, thereby achieving the effect of easy disassembly. At the same time, the pressing block 653 of the disassembly block 65 can be manually controlled through the cooperation of the slot 654, so that after pulling it upward, the adsorption block 652 can be disengaged from the upper surface of the collecting block 63, and the position plate 651 is pulled out at the same time, which allows the liquid to be opened. Liquid is cleaned at the center of the upper end of the collecting block 63, thus facilitating liquid cleaning. Conversely, after assembly, the vertical groove 655 allows the guide tube 67 in the rubber sleeve 66 to introduce liquid into the collecting block 63. At the same time, when the rubber sleeve 66 and the guide tube 67 are embedded in the lower end of the liquid collecting assembly 5, the rebound effect of the rubber sleeve 66 can improve the connection stability with the lower end of the liquid collecting assembly 5, replacing the original cumbersome connection. After pushing it in and aligning it, the large diameter and rebound effect of the rubber sleeve 66 are used to complete the splicing of the guide tube 67 and the liquid collecting assembly 5, which further improves the use effect of the device.

[0046] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solutions described in this invention, or by designing similar technical solutions by those skilled in the art under the inspiration of the technical solutions described in this invention, falls within the protection scope of this invention.
