Description

Technical Field

[0001] The present invention belongs to the technical field of sewage detection, and in particular relates to a sewage solid content detection device. Background Art

[0002] Solid content is a commonly used test indicator in the sewage treatment process. For example, in the activated sludge tank, solid content directly reflects the sludge concentration. In the sludge thickening tank, solid content can quantitatively reflect the sludge concentration multiple. In the sedimentation tank, solid content can reflect the sedimentation effect of the sedimentation tank. Conventional solid content testing requires steps such as sampling, filtration, drying, cooling, and weighing, involving equipment such as analytical balances, ovens, and dryers. The testing time is long, and it usually takes three to five hours to obtain the test results.

[0003] In order to solve this kind of problem, relevant technicians have proposed a solid content detection device as shown in CN118408858A. The device integrates extrusion dehydration, drying, weighing and other integrated structures. When using the device, the sewage in the holding tank needs to be squeezed out through the extrusion plate, and then the remaining residue is stirred and dried. However, during the stirring process, in order to better stir, the extrusion plate needs to be lifted away from the stirring blade, so that the residue in the holding tank is easily splashed on the extrusion plate and adhered, thereby causing the actual measured data to deviate.

[0022] The embodiments of the present invention are intended to introduce and illustrate the structural composition of a sewage solid content detection device and the coordination relationship between the various components. Unless otherwise specified, the dimensions, materials, and manufacturing processes of the various components suitable for the sewage solid content detection device in the embodiments of the present invention can be selected according to specific circumstances and are not specifically limited or explained here.

[0023] Furthermore, in order to provide the public with a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention, but those skilled in the art can fully understand the present invention without the description of these details.

[0024] Please also refer to Figure 1-Figure 5 This embodiment provides a sewage solid content detection device, including a supporting shell 10, a drying liner 11 provided with a receiving groove 12, a drying structure, a weighing component and a drainage structure, and also includes a mounting plate 20, a telescopic rod 21, a movable shaft barrel 22, an extrusion plate 23, a stirring mechanism 3, a driving component 4, a transmission component 5 and a pushing component 6; the supporting shell, the drying liner 11, the drying mechanism, the weighing component and the drainage structure can specifically refer to the structure shown in CN118408858A. Specifically, the drainage structure includes a sewage pipe, a valve, a permeate filter, a sealing ring, etc., and the drying mechanism includes a mounting seat, an electric heating pipe, etc. The above structure has been described in detail in CN118408858A and will not be repeated here in this application.

[0025] The mounting plate 20 is fixed on the supporting shell 10, the telescopic rod 21 is arranged on the mounting plate 20, the movable shaft barrel 22 is arranged at the telescopic end of the telescopic rod 21, and the extrusion plate 23 is arranged on the movable shaft barrel 22 away from the end of the telescopic rod 21; specifically, the telescopic rod 21 is an object such as a cylinder, a hydraulic cylinder, an electric telescopic rod 21, and the telescopic rod 21, the movable shaft barrel 22 and the extrusion plate 23 are coaxially arranged, and the extrusion plate 23 faces the accommodating groove 12 and is the same size as the accommodating groove 12.

[0026] The stirring mechanism 3 is rotatably and telescopically arranged in the movable shaft barrel 22 and can pass through the extrusion plate 23; the driving mechanism is arranged on the stirring mechanism 3 and can drive the stirring mechanism 3 to rotate; the transmission component 5 is rotatably arranged 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 arranged on the extrusion plate 23, and the rotation of the transmission component 5 can drive the pushing component 6 to rise and fall or maintain a height position, and the extension of the pushing component 6 can drive the stirring mechanism 3 to shorten.

[0027] That is, during the continuous rotation of the stirring mechanism 3, each rotation only drives the transmission assembly 5 to rotate a certain angle and then stops; during the rotation of the transmission assembly 5, the pushing assembly 6 either rises or falls or maintains a constant height position, and because each rotation of the stirring mechanism 3 only drives the transmission assembly 5 to rotate once, after the pushing assembly 6 drives the stirring mechanism 3 to shorten so that the stirring blade 332 of the stirring mechanism 3 abuts against the extrusion plate 23, the stirring mechanism 3 needs to rotate at least one more time to move the stirring blade 332 of the stirring mechanism 3 away from the extrusion plate 23. Preferably, the distance each time the pushing assembly 6 is lifted or lowered is the distance from the stirring blade 332 of the stirring mechanism 3 to the extrusion plate 23, or the distance each time the pushing assembly 6 is lowered is the distance from the stirring blade 332 to the extrusion plate 23, and multiple lifts are required to make the stirring blade 332 abut against the extrusion plate 23. After the device shown in the present application completes squeezing the sewage, it is necessary to operate the telescopic rod 21 to lift the squeezing plate 23 to a fixed height, which is preferably at the same height as the top surface of the drying liner 11. This operation can be performed manually or through corresponding program settings to lift it to a specified height. At this time, the height from the stirring blade 332 to the squeezing plate 23 is the height to which the stirring mechanism 3 is lifted by the driving component 6.

[0028] In the present application, the rotation of the stirring mechanism 3 causes the pushing component 6 to extend through the transmission component 5, thereby driving the stirring component 33 to shorten, so that the stirring blade 332 of the stirring mechanism 3 abuts 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. Furthermore, each rotation of the stirring mechanism 3 only causes the transmission assembly 5 to rotate once. After the stirring blade 332 abuts the extrusion plate 23, it must rotate at least one more time before it moves away from the extrusion plate 23. This allows for more extensive removal of solid contaminants adhering to the extrusion plate 23. Specifically, the stirring blade 332 of the stirring mechanism 3 lifts up and abuts the extrusion plate 23 after multiple rotations, and then moves away from the extrusion plate 23 after at least one rotation.

[0029] 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 fixedly mounted within 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 toward 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 cause the rotating assembly to slide, but the rotation of the rotating assembly does not cause the sliding assembly 32 to rotate.

[0030] In other embodiments, the sliding assembly 32 includes a sliding tube 321 and a push plate 322. One end of the sliding tube 321 is slidably connected to the fixed tube, and the other end is rotatably connected to the rotating assembly. The push plate 322 is fixed to the sliding tube 321. The extension of the push assembly 6 can push the push plate 322 to slide toward the fixed tube. Preferably, the push plate 322 is an annular plate.

[0031] In other embodiments, the stirring assembly 33 includes a stirring shaft 331, a stirring blade 332, a stirring gear ring 333, a turntable 334, a toggle 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 blade 332 is fixed to the end of the stirring shaft 331 away from the movable shaft barrel 22, the stirring gear ring 333 is coaxially fixed to the stirring shaft 331, and the driving assembly 4 can drive the stirring gear ring 333 to rotate; the turntable 334 is coaxially fixed to the stirring shaft 331, the toggle lever 335 is eccentrically arranged on the turntable 334, and can intermittently drive the transmission assembly 5 to rotate; the limiting protrusion 336 is coaxially fixed to the turntable 334, and can limit the position of the transmission assembly 5 in the rotation gap. It should be understood that the extrusion plate 23 is provided with a through hole that the stirring shaft 331 can just pass through. Preferably, the stirring shaft 331 is also provided with a waterproof pad on the through hole. Specifically, an annular groove is provided within the sliding tube 321, and the stirring shaft 331 is slidably connected within the groove via a slider, thereby achieving a rotational connection between the stirring shaft 331 and the sliding tube 321. Rotation of the stirring shaft 331 does not cause rotation of the sliding tube 321. It should also be understood that the distance from the top of the limiting protrusion 336 and the top of the toggle lever 335 to the turntable 334 is greater than the distance from the stirring blade 332 to the extrusion plate 23.

[0032] In other embodiments, the drive assembly 4 includes a drive link 41, a drive motor 42, and a drive gear 43. The drive link 41 is fixed to the sliding assembly 32, the drive motor 42 is fixed to the drive link 41, and the drive gear 43 is coaxially fixed to the output shaft of the drive motor 42. The drive gear 43 can drive the stirring assembly 33 to rotate. Specifically, the drive link 41 is fixed to the sliding tube 321, and the drive gear 43 is engaged with the stirring gear ring 333.

It should be understood that the pushing assembly 6 is slidably connected in the arcuate chutes 511 and can move from the bottom horizontal arcuate chutes 511 to the top horizontal arcuate chutes 511 under the rotation of the transmission column 51. The distance between the top horizontal arcuate chutes 511 and the bottom horizontal arcuate chutes 511 is equal to or slightly greater than the distance between the stirring blade 332 and the extrusion plate 23. By adjusting the length of the top horizontal arcuate chutes 511, the angle of rotation of the stirring blade after lifting can be adjusted, preferably rotating 450 degrees after lifting.

[0034] In other embodiments, the push assembly 6 includes a fixed sleeve 61, a push post 62, and a connecting rod 63. The fixed sleeve 61 is fixed to the extrusion plate 23, and the push post 62 is slidably connected to the fixed sleeve 61 so as to be liftable. The push post 62 is slidably connected to the fixed sleeve 61 and is slidably connected to the arc-shaped slide 511 via the connecting rod 63. Specifically, the fixed sleeve 61 is provided with a vertical slide, and the connecting rod 63 is preferably retractable.

At the same time, the stirring blade 332 is preferably made of a flexible material such as rubber.

[0036] The sewage solid content detection device can intermittently scrape off the solid residues adhering to the extrusion plate during stirring, so that the measurement result is more accurate.
