Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a solid-liquid separation device for water quality detection. Background Art

[0002] The solid-liquid separation device for water quality testing is a device used to separate the solid and liquid parts of water. The purpose of solid-liquid separation is to accurately determine the content of different pollutants in the water sample. Solid-liquid separation can separate the solid particles in the water sample from the water, so that the concentration of pollutants such as chemicals and microorganisms in the water sample can be more accurately and conveniently determined during the detection process. Through solid-liquid separation, the interference of solid particles on the measurement results can be avoided, and the accuracy and long-term stability of the detection instrument can be better protected. Therefore, solid-liquid separation is of great significance in water quality testing;

[0003] Patent No. "CN216062163U" discloses a "solid-liquid separation device for water quality detection in environmental engineering". The device filters water through multiple filter screens to better separate solids and liquids, thereby achieving better separation effects. At the same time, it is convenient for staff to install and disassemble the filter screens, thereby improving the efficiency of installation and disassembly, thereby facilitating staff to clean the filter screens and improving the efficiency of cleaning. Since the amount of solid impurity particles inside the water sample is not limited, the more the water sample is separated, the more solid impurity particles will accumulate in the device. Once too much impurity accumulates above the limiting filter plate during the filtration process, it will directly affect the solid-liquid separation effect of the water sample. In severe cases, it will directly cause the water sample to be unable to be separated. However, the above-mentioned device only sets the filter screen to be detachable, and its method of clearing blockage is to remove the filter screen for cleaning. It is unable to deal with the blockage caused during the filtration of the water sample. Removing the filter screen will cause the water sample to be lost, and the overall practical effect is poor.

Compared with the general static filtration, this design greatly accelerates the solid-liquid separation speed of the water sample. With the mechanism transmission driving the cam to rotate, when the cam rotates back and forth and contacts the limit filter plate, the limit filter plate will be in a continuous vibration state. Then, through the design of the limit filter plate vibration, the solid impurity particles above the limit filter plate can be shaken off, and part of the water sample can also be shaken off, so as to achieve the effect of accelerating the filtration and separation of the water sample, and the phenomenon that the water sample cannot be separated due to the accumulation of solid impurities during the separation process will not occur.

At the same time, when the sealing cover is separated from the separation barrel, the transmission mechanism parts above the limiting filter plate will be taken out together, so that there is no obstruction from the parts, and the above of the limiting filter plate presents a cavity structure, which greatly facilitates the subsequent cleaning work of the limiting filter plate. The overall structure is simple and the practical effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] When implementing: Figure 1-6 As shown, a solid-liquid separation device for water quality detection includes a supporting base 1, a separation barrel 2 and a sealing cover 3: the top outer wall of the supporting base 1 is provided with the separation barrel 2, the top outer wall of the separation barrel 2 is fitted with the sealing cover 3, the interior of the separation barrel 2 is provided with a cleaning and anti-blocking mechanism 4, a portable cleaning mechanism 5 is provided below the sealing cover 3, and an auxiliary separation mechanism 6 is provided below the portable cleaning mechanism 5, the cleaning and anti-blocking mechanism 4 includes a limiting filter plate 41, a limiting T-shaped block 42, a limiting T-shaped groove 43, a positioning support frame 44, a driving motor 45, a transmission shaft 46, a placement groove 47, a piston rod 48, a resisting spring 49 and a limiting scraper 410, the interior of the separation barrel 2 is provided with a limiting filter plate 41, the side outer wall of the limiting filter plate 41 is symmetrically provided with a limiting T-shaped block 42, and the side inner wall of the separation barrel 2 is symmetrically provided with a limiting T shaped groove 43, the limiting T-shaped block 42 and the limiting T-shaped groove 43 are slidably installed, the top outer wall of the sealing cover 3 is provided with a positioning support frame 44, the top outer wall of the positioning support frame 44 is provided with a driving motor 45, the driving motor 45 is connected to the top outer wall of the transmission shaft 46, the transmission shaft 46 is located at the bottom position of the internal embedded with a placement groove 47, the placement groove 47 is slidably installed with a piston rod 48, the top outer wall of the piston rod 48 and the top inner wall of the placement groove 47 are connected with a resistance spring 49, the protruding end of the piston rod 48 is arranged below the transmission shaft 46, the side outer wall of the transmission shaft 46 at the bottom position is provided with a limiting scraper 410, the limiting scraper 410 is set to be "L"-shaped, and the bottom outer wall of the limiting scraper 410 is in contact with the top outer wall of the limiting filter plate 41; as shown in the attached manual Figure 1As shown, a feed funnel is pre-installed on the top of the sealing cover 3. When it is necessary to separate the solid and liquid of the water sample to be tested, the water sample must first be poured into the separation barrel 2 through the feed funnel. The setting of the limiting filter plate 41 here is convenient for filtering the solid waste in the water sample, and then the solid particle impurities will automatically accumulate and be isolated above the limiting filter plate 41. The filtered water sample will fall into the collection box. When it is necessary to accelerate the filtering speed of the water sample, it is only necessary to turn on the driving motor 45. The setting of the positioning support frame 44 here has an auxiliary supporting effect on the driving motor 45. When the driving motor 45 After the motor 45 is turned on, it will automatically drive the transmission shaft 46 to rotate. Here, the resistance spring 49 connects the transmission shaft 46 and the piston rod 48 together, so that the rotation of the transmission shaft 46 will automatically drive the piston rod 48 to rotate and then drive the limiting scraper 410 to rotate. When the limiting scraper 410 rotates, it will automatically clean the solid impurity particles accumulated above the limiting filter plate 41, thereby accelerating the filtration speed of the water sample. Here, the setting of the limiting T-shaped block 42 and the limiting T-shaped groove 43 not only provides mobile support for the limiting filter plate 41, but also has a limiting effect on the limiting filter plate 41.

[0025] The top outer wall and the bottom outer wall of the limiting filter plate 41 are both provided with annular protective plates, and the side outer walls of the annular protective plates are in contact with the side inner walls of the separation barrel 2, and the longitudinal height of the annular protective plates is greater than the groove height of the limiting T-shaped groove 43; the setting of the annular protective plates here achieves the effect of closed protection for the limiting T-shaped groove 43, and no matter how the limiting filter plate 41 is subsequently displaced up and down, the annular protective plates will cover and protect the limiting T-shaped groove 43, thereby preventing foreign particles from being stuck in the inside of the limiting T-shaped groove 43 during the up and down movement of the limiting filter plate 41.

[0026] The portable cleaning mechanism 5 includes a threaded ring 51 and a threaded groove 52. The bottom outer wall of the sealing cover 3 is provided with a threaded ring 51, and the top outer wall of the separation barrel 2 is provided with a threaded groove 52. The threaded ring 51 and the threaded groove 52 are threadedly installed. When the separation barrel 2 and the sealing cover 3 need to be disassembled in order to clean the solid impurity particles accumulated above the limiting filter plate 41, at this time, it is only necessary to rotate the sealing cover 3 until the threaded ring 51 is completely separated from the threaded groove 52. The installation is similar, and then the limiting filter plate 41 can be directly cleaned.

[0027] The auxiliary separation mechanism 6 includes an auxiliary support frame 61, and the side outer wall of the separation barrel 2 is provided with an auxiliary support frame 61, the auxiliary support frame 61 is arranged in an "L" shape, and the bottom outer wall of the auxiliary support frame 61 is provided with a support column, and the support column is connected to the top outer wall of the support base 1, and the side inner wall of the auxiliary support frame 61 is provided with a control motor 62, and the control motor 62 is connected to the outer wall of one side of the support shaft 63, and the outer wall of the other side of the support shaft 63 is rotatably installed with the side inner wall of the separation barrel 2, and a limit cam 64 is symmetrically arranged on the outside of the support shaft 63 located inside the separation barrel 2, and the limit cam 64 is located below the limit filter plate 41; when there are a lot of solid impurity particles accumulated above the limit filter plate 41 and the filtration speed of the water sample needs to be accelerated, at this time, the control motor 62 needs to be turned on first, and the setting of the auxiliary support frame 61 here has an auxiliary support effect on the control motor 62. When the control motor 62 is turned on, it will automatically drive the support shaft 63 to rotate and then drive When the movable limit cam 64 rotates, and when the limit cam 64 conflicts with the limit filter plate 41 during the rotation process, the limit filter plate 41 will automatically move upward due to the resistance force, thereby driving the limit T-shaped block 42 to slide inside the limit T-shaped groove 43. At the same time, the piston rod 48 automatically slides inside the placement groove 47 due to the extrusion of the limit filter plate 41 and synchronously squeezes the resistance spring 49 to put it in a contracted state. When the limit cam 64 does not conflict with the limit filter plate 41 during the rotation process, the resistance spring 49 will automatically pop open due to the extrusion force and drive the piston rod 48 to reset. When the piston rod 48 is reset, it will automatically conflict with the limit filter plate 41 and move downward and drive the limit filter plate 41 to reset. In this way, through the above working process, the limit filter plate 41 is in a state of continuous vibration, thereby the solid impurity particles above the limit filter plate 41 can be shaken off, and part of the water sample can also be shaken off, thereby achieving the effect of accelerating the filtration and separation of the water sample.

[0028] The annular protective plate located on the outer wall of the bottom end of the limiting filter plate 41 is set as an opening structure on both sides, and the opening structure is located at the installation position of the support shaft 63; the protective plate below the limiting filter plate 41 is set as an opening structure at the installation position of the support shaft 63, which on the one hand provides an installation space for the support shaft 63, and on the other hand ensures that the limiting filter plate 41 will not be stuck by the support shaft 63 during the up and down movement.

[0029] A material taking trough is provided on the side outer wall of the separation barrel 2 at the bottom, and a collection box is provided on the bottom inner wall of the separation barrel 2; the provision of the collection box here facilitates the centralized collection of separated water samples.

[0030] When using this utility model, as shown in the attached manual Figure 1As shown, a feed funnel is pre-installed on the top of the sealing cover 3. When it is necessary to separate the solid and liquid of the water sample to be tested, the water sample must first be poured into the separation barrel 2 through the feed funnel. The setting of the limiting filter plate 41 here is convenient for filtering the solid waste in the water sample, and then the solid particle impurities will automatically accumulate and be isolated above the limiting filter plate 41. The filtered water sample will fall into the collection box. When it is necessary to accelerate the filtering speed of the water sample, it is only necessary to turn on the driving motor 45. The setting of the positioning support frame 44 here has an auxiliary supporting effect on the driving motor 45. When the driving motor 45 After the motor 45 is turned on, it will automatically drive the transmission shaft 46 to rotate. Here, the resistance spring 49 connects the transmission shaft 46 and the piston rod 48 together, so that the rotation of the transmission shaft 46 will automatically drive the piston rod 48 to rotate and then drive the limiting scraper 410 to rotate. When the limiting scraper 410 rotates, it will automatically centrally clean the solid impurity particles accumulated on the limiting filter plate 41, thereby accelerating the filtering speed of the water sample. Here, the setting of the limiting T-shaped block 42 and the limiting T-shaped groove 43 not only provides a mobile support for the limiting filter plate 41, but also has a limiting effect on the limiting filter plate 41.

[0031] When there are many solid impurity particles accumulated above the limiting filter plate 41 and the filtering speed of the water sample needs to be accelerated, the control motor 62 needs to be turned on first. The setting of the auxiliary support frame 61 here plays an auxiliary supporting effect on the control motor 62. When the control motor 62 is turned on, it will automatically drive the support shaft 63 to rotate and then drive the limiting cam 64 to rotate. When the limiting cam 64 conflicts with the limiting filter plate 41 during the rotation process, the limiting filter plate 41 will automatically move upward due to the resistance force and then drive the limiting T-shaped block 42 to slide inside the limiting T-shaped groove 43. At the same time, the piston rod 48 automatically slides inside the placement groove 47 due to the extrusion effect of the limiting filter plate 41 and synchronously squeezes the resistance spring 49 to make it in a contracted state. When the limiting cam 64 conflicts with the limiting filter plate 41 during the rotation process, 1 does not interfere, the interference spring 49 will automatically pop open and drive the piston rod 48 to reset when it is not subjected to the squeezing force. After the piston rod 48 is reset, it will automatically interfere with the limiting filter plate 41 to move downward and drive the limiting filter plate 41 to reset. Through the above working process, the limiting filter plate 41 is in a state of continuous vibration, so that the solid impurity particles above the limiting filter plate 41 can be shaken off, and part of the water sample can also be shaken off, so as to achieve the effect of accelerating the filtration and separation of the water sample; when it is necessary to separate the separation barrel 2 and the sealing cover 3 in order to clean the solid impurity particles accumulated above the limiting filter plate 41, it is only necessary to rotate the sealing cover 3 until the threaded ring 51 is completely separated from the threaded groove 52. The installation is similar, and then the limiting filter plate 41 can be directly cleaned.

[0032] It is noted here that the drive motor 45 and the control motor 62 can be powered by existing technology, whether it is powered by a power supply component or an external wire, which belongs to the existing conventional operating technical means and will not be described in detail here.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
