Description

Technical Field

[0001] This invention belongs to the field of wastewater testing technology, specifically, it relates to a wastewater solids content testing device. Background Technology

[0002] Solid content is a commonly used indicator in wastewater treatment. For example, in activated sludge tanks, solid content directly reflects sludge concentration; in sludge thickening tanks, solid content can quantitatively reflect the sludge thickening factor; and in sedimentation tanks, solid content can reflect the sedimentation effect of the sedimentation tank.

[0003] In conventional solid content testing, steps such as sampling, filtration, drying, cooling, and weighing are required, involving equipment such as analytical balances, ovens, and desiccators. The testing time is long, usually requiring three to five hours to obtain the test results.

[0004] To address this issue, relevant technicians proposed a solids content testing device as shown in CN118408858A. This device integrates a single structure for extrusion dewatering, drying, and weighing. During use, the wastewater in the container tank needs to be squeezed out through the extrusion plate, followed by stirring and drying of the remaining residue. However, during the stirring process, in order to achieve better stirring, the extrusion plate needs to be lifted away from the stirring blades, which makes it easy for the residue in the container tank to splash onto the extrusion plate and stick together, thus causing some deviation in the actual measured data. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a wastewater solids content detection device to solve the technical problem mentioned in the background art that the residues in the stirring process during solids content detection are easily splashed and adhered to the extrusion plate.

[0006] To achieve the aforementioned objectives, the technical solution adopted by this invention includes:

[0007] A wastewater solids content testing device includes a supporting shell, a drying inner liner with a receiving tank, a drying structure, a weighing component and a drainage structure, and also includes a mounting plate, a telescopic rod, a movable shaft barrel, a squeezing plate, a stirring mechanism, a driving component, a transmission component and a pushing component;

[0008] The mounting plate is fixed to the supporting shell, the telescopic rod is mounted on the mounting plate, the movable shaft barrel is located at the telescopic end of the telescopic rod, and the pressing plate is located on the movable shaft barrel at the end away from the telescopic rod.

[0009] The stirring mechanism is rotatably and retractably disposed within the movable shaft barrel and can pass through the extrusion plate; the driving mechanism is disposed on the stirring mechanism and can drive the stirring mechanism to rotate; the transmission component is rotatably disposed on the extrusion plate, and each rotation of the stirring component can drive the transmission component to rotate once; the pushing component is retractably disposed on the extrusion plate, and the rotation of the transmission component can drive the pushing component to rise or fall or maintain a height position, and the extension of the pushing component can drive the stirring mechanism to shorten.

[0010] Furthermore, the stirring mechanism includes a fixed rod, a sliding assembly, and a stirring assembly; the fixed rod is fixed inside the movable shaft barrel, the sliding assembly is slidably connected to the fixed rod, and the extension of the pushing assembly can push the sliding assembly to slide closer to the fixed rod; the stirring assembly is rotatably connected to the sliding assembly and passes through the extrusion plate.

[0011] Furthermore, the sliding assembly includes a sliding tube and a pusher plate; one end of the sliding tube is slidably connected to the fixed tube, and the other end is rotatably connected to the rotating assembly; the pusher plate is fixed on the sliding tube, and the extension of the pusher assembly can push the pusher plate to slide towards the fixed tube.

[0012] Furthermore, the stirring assembly includes a stirring shaft, stirring blades, a stirring toothed ring, a turntable, a lever, and a limiting protrusion; the stirring shaft is rotatably connected to the sliding assembly and passes through the extrusion plate; the stirring blades are fixed on the stirring shaft at one end away from the moving shaft barrel; the stirring toothed ring is coaxially fixed on the stirring shaft; the driving assembly can drive the stirring toothed ring to rotate; the turntable is coaxially fixed on the stirring shaft; the lever is eccentrically disposed on the turntable and can intermittently drive the transmission assembly to rotate; the limiting protrusion is coaxially fixed on the turntable and can limit the position of the transmission assembly during rotational gaps.

[0013] Furthermore, the driving assembly includes a driving connecting plate, a driving motor, and a driving gear; the driving connecting plate is fixed on the sliding assembly, the driving motor is fixed on the driving connecting plate, and the driving gear is coaxially fixed on the output shaft of the driving motor, and the driving gear can drive the stirring assembly to rotate.

[0014] Furthermore, the transmission mechanism includes a transmission column and a grooved wheel; the transmission shaft is rotatably connected to the extrusion plate, the grooved wheel is coaxially fixed on the transmission column, and the stirring assembly can intermittently drive the transmission column to rotate; the transmission column is provided with arc-shaped grooves of different heights in the circumferential direction, and the two ends of the two horizontal arc-shaped grooves are connected by oblique arc-shaped grooves respectively.

[0015] Furthermore, the pushing assembly includes a fixed sleeve, a pushing column, and a connecting rod; the fixed sleeve is fixed to the extrusion plate, the pushing column is slidably connected to the fixed sleeve in a vertical manner, and is slidably connected to the arc-shaped groove through the connecting rod.

[0016] Furthermore, the stirring blades have an inclined surface facing the extrusion plate.

[0017] Compared with the prior art, the advantages of the present invention include:

[0018] In this application, the rotation of the stirring mechanism causes the pushing component to extend through the transmission component, which in turn causes the stirring component to shorten, so that the stirring blades of the stirring mechanism abut against the extrusion plate. As the stirring mechanism continues to rotate, the solid contaminants adhering to the extrusion plate can be scraped off, thereby reducing the possibility of solid contaminants remaining on the extrusion plate.

[0019] In addition, each rotation of the mixing mechanism only drives the transmission component to rotate once. After the mixing blades come into contact with the extrusion plate, they need to rotate at least one more revolution before moving away from the extrusion plate, allowing for a more comprehensive cleaning of the solid contaminants adhering to the extrusion plate. In other words, the mixing blades of the mixing mechanism rise and come into contact with the extrusion plate after several revolutions, and then rotate at least one more revolution before moving away from the extrusion plate.

[0033] The present invention aims to introduce and explain the structural composition of a wastewater solids content detection device and the cooperation relationship between the various components. Unless otherwise specified, the dimensions, materials and manufacturing processes of the various components in the wastewater solids content detection device in the present invention can be selected according to specific circumstances, and no special limitations or explanations are made here.

[0034] Furthermore, to provide the public with a better understanding of the present invention, certain specific details are described in detail in the following description of the invention. However, those skilled in the art will fully understand the invention even without these detailed descriptions.

[0035] Please refer to the following: Figures 1-5 This embodiment provides a wastewater solids content detection device, including a supporting shell 10, a drying inner liner 11 with a receiving groove 12, a drying structure, a weighing component, and a drainage structure. It also includes a mounting plate 20, a telescopic rod 21, a movable shaft barrel 22, a pressing plate 23, a stirring mechanism 3, a driving component 4, a transmission component 5, and a pushing component 6. The supporting shell, drying inner liner 11, drying mechanism, weighing component, and drainage structure can be specifically referred to the structure shown in CN118408858A. Specifically, the drainage structure includes a sewage pipe, valves, a permeable filter, a sealing ring, etc., and the drying mechanism includes a mounting base, an electric heating tube, etc. The above structure has been described in detail in CN118408858A, and will not be repeated here.

[0036] Mounting plate 20 is fixed on supporting housing 10, telescopic rod 21 is mounted on mounting plate 20, movable shaft barrel 22 is mounted on telescopic end of telescopic rod 21, and pressing plate 23 is mounted on movable shaft barrel 22 at the end away from telescopic rod 21. Specifically, telescopic rod 21 is a cylinder, hydraulic cylinder, electric telescopic rod 21, etc., and telescopic rod 21, movable shaft barrel 22 and pressing plate 23 are coaxially arranged. Pressing plate 23 faces receiving groove 12 and is the same size as receiving groove 12.

[0037] The stirring mechanism 3 is rotatably and telescopically disposed within the movable shaft barrel 22 and can pass through the extrusion plate 23; the driving mechanism is disposed on the stirring mechanism 3 and can drive the stirring mechanism 3 to rotate; the transmission component 5 is rotatably disposed on the extrusion plate 23, and each rotation of the stirring component 33 can drive the transmission component 5 to rotate once; the pushing component 6 is telescopically disposed on the extrusion plate 23, and the rotation of the transmission component 5 can drive the pushing component 6 to rise or fall or maintain a height position, and the extension of the pushing component 6 can drive the stirring mechanism 3 to shorten.

[0038] That is, during the continuous rotation of the stirring mechanism 3, each rotation only drives the transmission component 5 to rotate a certain angle before stopping; during the rotation of the transmission component 5, the pushing component 6 either rises or falls or maintains a constant height position. Since each rotation of the stirring mechanism 3 only drives the transmission component 5 to rotate once, after the pushing component 6 shortens the stirring mechanism 3 so that the stirring blades 332 of the stirring mechanism 3 abut against the extrusion plate 23, the stirring mechanism 3 needs to rotate at least one more revolution to move the stirring blades 332 away from the extrusion plate 23. Preferably, the distance of each rise or fall of the pushing component 6 is the distance from the stirring blades 332 of the stirring mechanism 3 to the extrusion plate 23, or the distance of each fall of the pushing component 6 is the distance from the stirring blades 332 to the extrusion plate 23, requiring multiple rises to make the stirring blades 332 abut against the extrusion plate 23. After the device shown in this application has squeezed the sewage, it is necessary to operate the telescopic rod 21 to raise the squeezing plate 23 to a fixed height. This height is preferably the position of the top surface of the drying inner tank 11. This operation process can be manually or by setting the corresponding program to raise it to the specified height. At this time, the height of the stirring blade 332 to the squeezing plate 23 is the height raised by the stirring mechanism 3 under the influence of the pushing component 6.

[0039] In this application, the rotation of the stirring mechanism 3 causes the pushing component 6 to extend through the transmission component 5, which in turn causes the stirring component 33 to shorten, so that the stirring blades 332 of the stirring mechanism 3 abut against the extrusion plate 23. As the stirring mechanism 3 continues to rotate, the solid contaminants adhering to the extrusion plate 23 can be scraped off, thereby reducing the possibility of solid contaminants remaining on the extrusion plate 23.

[0040] Furthermore, each rotation of the stirring mechanism 3 only drives the transmission component 5 to rotate once. After the stirring blade 332 comes into contact with the extrusion plate 23, it needs to rotate at least one more revolution before moving away from the extrusion plate 23, allowing the solid contaminants adhering to the extrusion plate 23 to be cleaned more extensively. That is, the stirring blade 332 of the stirring mechanism 3 rises and comes into contact with the extrusion plate 23 after several revolutions, and only moves away from the extrusion plate 23 after rotating at least one revolution.

[0041] In other embodiments, the stirring mechanism 3 includes a fixed rod 31, a sliding assembly 32, and a stirring assembly 33. The fixed rod 31 is fixed inside the movable shaft barrel 22, and the sliding assembly 32 is slidably connected to the fixed rod 31. The extension of the pushing assembly 6 can push the sliding assembly 32 to slide closer to the fixed rod 31. The stirring assembly 33 is rotatably connected to the sliding assembly 32 and passes through the extrusion plate 23. It should be understood that the sliding of the sliding assembly 32 can drive the rotating assembly to slide, but the rotation of the rotating assembly does not drive the sliding assembly 32 to rotate.

[0042] In other embodiments, the sliding assembly 32 includes a sliding tube 321 and a pusher plate 322; one end of the sliding tube 321 is slidably connected to the fixed tube, and the other end is rotatably connected to a rotating assembly; the pusher plate 322 is fixed on the sliding tube 321, and the extension of the pusher assembly 6 can push the pusher plate 322 to slide towards the fixed tube. Preferably, the pusher plate 322 is an annular plate.

[0043] In other embodiments, the stirring assembly 33 includes a stirring shaft 331, stirring blades 332, stirring toothed ring 333, a turntable 334, a lever 335, and a limiting protrusion 336. The stirring shaft 331 is rotatably connected to the sliding assembly 32 and passes through the extrusion plate 23. The stirring blades 332 are fixed on the stirring shaft 331 at the end away from the moving shaft barrel 22. The stirring toothed ring 333 is coaxially fixed on the stirring shaft 331, and the driving assembly 4 can drive the stirring toothed ring 333 to rotate. The turntable 334 is coaxially fixed on the stirring shaft 331. The lever 335 is eccentrically disposed on the turntable 334 and can intermittently drive the transmission assembly 5 to rotate. The limiting protrusion 336 is coaxially fixed on the turntable 334 and can limit the position of the transmission assembly 5 during rotational gaps. It should be understood that the extrusion plate 23 is provided with a through hole through which the stirring shaft 331 can just pass. Preferably, the stirring shaft 331 is also provided with a waterproof gasket in the through hole. Specifically, the sliding tube 321 has an annular groove, and the stirring shaft 331 is slidably connected to the groove via a slider, realizing the rotational connection between the stirring shaft 331 and the sliding tube 321. The rotation of the stirring shaft 331 does not cause the sliding tube 321 to rotate. It should also be understood that the distances from the top of the limiting protrusion 336 and the top of the actuating rod 335 to the turntable 334 are both greater than the distance from the stirring blade 332 to the extrusion plate 23.

[0044] In other embodiments, the drive assembly 4 includes a drive connecting plate 41, a drive motor 42, and a drive gear 43. The drive connecting plate 41 is fixed to the sliding assembly 32, the drive motor 42 is fixed to the drive connecting plate 41, and the drive gear 43 is coaxially fixed to the output shaft of the drive motor 42, enabling the stirring assembly 33 to rotate. Specifically, the drive connecting plate 41 is fixed to the sliding tube 321, and the drive gear 43 meshes with the stirring gear ring 333.

[0045] In other embodiments, the transmission mechanism includes a transmission column 51 and a grooved wheel 52; the transmission shaft is rotatably connected to the extrusion plate 23, and the grooved wheel 52 is coaxially fixed to the transmission column 51; the stirring assembly 33 can intermittently drive the transmission column 51 to rotate; the transmission column 51 is circumferentially provided with arc-shaped grooves 511 of different heights, and the two ends of the two horizontal arc-shaped grooves 511 are connected by oblique arc-shaped grooves 511 respectively. It should be understood that the pushing assembly 6 is slidably connected within the arc-shaped grooves 511 and can move from the bottom horizontal arc-shaped groove 511 to the top horizontal arc-shaped groove 511 under the rotational push of the transmission column 51; the distance between the top horizontal arc-shaped groove 511 and the bottom horizontal arc-shaped groove 511 is equal to or slightly greater than the distance from the stirring blade 332 to the extrusion plate 23. By adjusting the length of the top horizontal arc-shaped groove 511, the angle of rotation of the stirring blade after being lifted can be adjusted, preferably 450° after being lifted.

[0046] In other embodiments, the pushing assembly 6 includes a fixed sleeve 61, a pushing column 62, and a connecting rod 63; the fixed sleeve 61 is fixed to the extrusion plate 23, the pushing column 62 is slidably connected to the fixed sleeve 61 and slidably connected to the arc-shaped groove 511 via the connecting rod 63. Specifically, the fixed sleeve 61 is provided with a vertical groove, and the connecting rod 63 is preferably telescopic.

[0047] In other embodiments, the stirring blade 332 has an inclined surface facing the extrusion plate 23. This inclined surface scoops up solid residue during stirring, resulting in more uniform mixing. The stirring blade 332 is preferably made of a flexible material such as rubber.

[0048] The aforementioned wastewater solids content detection device can intermittently scrape off solid residues adhering to the extrusion plate during stirring, making the measurement results more accurate.

[0049] It should be understood that the above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. It should not be considered that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the protection scope of the present invention.
