Description

Technical Field

[0001] The invention belongs to the technical field of sewage detection, and in particular relates to a rapid 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 detection requires steps such as sampling, filtration, drying, cooling, and weighing, involving equipment such as analytical balances, ovens, and dryers. The detection time is long, usually taking three to five hours to obtain the test results. Moreover, the entire process is affected by the operator's skill level, resulting in a large lag in the adjustment of operating parameters at the sewage treatment site. In view of this, a rapid solid content detection device is proposed to solve the above problems.

[0003] The solid content detection device shown in CN118408858A, by setting up a drying and squeezing structure, a stirring structure, a drying component and a sewage discharge component, can achieve the effect of quickly draining sewage containing sludge, and quickly drying and stirring and drying the drained sludge, so that a large amount of equipment is no longer required in the sewage solid content detection process.

[0004] However, the stirring structure of the device is located outside the extrusion plate, so that the contact depth between the extrusion plate and the sewage cannot reach the bottom due to the interference of the stirring mechanism during sewage extrusion, thereby making it difficult to squeeze some sewage and solid pollutants and increasing the drying time.

Unless otherwise specified, the dimensions, materials, and manufacturing processes of the various components suitable for the rapid 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.

[0026] 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.

[0027] Please also refer to Figures 1-4This embodiment provides a rapid solid content detection device, comprising an outer support shell 10, a drying inner container 11 having a receiving groove 12, a drying mechanism, a weighing assembly, and a drainage structure. The device also comprises a mounting plate 2, a telescopic rod 21, a movable shaft barrel 3, a squeezing plate 31, a stirring mechanism 4, a driving assembly 5, a first rack 6, a limiting block 7, a driven mechanism 8, and a pushing assembly 9. The supporting shell, drying liner 11, drying mechanism, weighing assembly and drainage structure can specifically refer to the structure shown in CN118408858A. Specifically, the drainage structure includes a sewage pipe, a valve, an infiltration 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 this application will not repeat it here.

[0028] The mounting plate 2 is fixed on the outer support shell 10, the telescopic rod 21 is arranged on the mounting plate 2, the movable shaft barrel 3 is arranged on the telescopic rod 21, and the extrusion plate 31 is fixed on the movable shaft barrel 3 away from one end of the telescopic rod 21; specifically, the telescopic rod 21 is a hydraulic cylinder or a pneumatic cylinder, etc., the movable shaft barrel 3, the extrusion plate 31 and the telescopic rod 21 are coaxial, and the size of the extrusion plate 31 is the same as the accommodating groove 12. The extension and contraction of the telescopic rod 21 can drive the extrusion plate 31 to move toward the accommodating groove 12.

[0029] The stirring mechanism 4 is telescopically and rotatably arranged in the movable shaft barrel 3, and the driving assembly 5 is arranged on the stirring mechanism 4 and can drive the stirring mechanism 4 to rotate; specifically, the extrusion plate 31 is provided with a through groove corresponding to the stirring mechanism 4, In the initial state, the stirring mechanism 4 is located in the through groove and can extend downward through the through groove.

[0030] The first rack 6 and the limit block 7 are respectively slidably provided on the mounting plate 2, and the limit block 7 can limit the position of the first rack 6; the driven mechanism 8 is provided on the stirring mechanism 4, and the pushing mechanism is telescopically fixed in the movable shaft barrel 3. The rising of the movable shaft barrel 3 can make the first rack 6 drive the driven mechanism 8 to rotate unidirectionally, so that the pushing mechanism extends and squeezes the stirring mechanism 4, thereby extending the stirring mechanism 4.

[0031] Specifically, the driven mechanism 8 is fixed to the fixed end of the stirring mechanism 4 and maintains a constant vertical position relative to the movable shaft barrel 3. Due to the unidirectional motion of the driven mechanism 8, when the movable shaft barrel 3, i.e., the driven assembly 83, descends, the first rack 6 cannot extend the pushing assembly 9 via the driven assembly 83. When the movable shaft barrel 3, i.e., the driven assembly 83, ascends, the first rack 6 extends the pushing assembly 9 via the driven assembly 83. The extension of the pushing assembly 9 pushes the stirring mechanism 4 to extend and pass through the extrusion plate 31. When the stirring assembly 43 needs to be reset upward, the sliding limit block 7 moves it away from the first rack 6, thereby moving the first rack 6 away from the driven mechanism 8, thereby retracting the stirring mechanism 4.

[0032] In the present application, due to the unidirectional motion of the driven mechanism 8, when the extrusion plate 31 moves toward the receiving tank 12 to squeeze the sewage in the receiving tank 12, the stirring mechanism 4 remains in the movable shaft barrel 3, thereby enabling the extrusion plate 31 to squeeze a larger volume of sewage. When the extrusion is completed and lifted, the first rack 6 drives the pushing assembly 9 to extend through the driven mechanism 8, pushing the stirring assembly 43 out of the extrusion plate 31, thereby stirring the remaining solids in the receiving tank 12. As a result, the present application can squeeze a larger volume of sewage and shorten the time required for drying.

[0033] In other embodiments, the stirring mechanism 4 includes a fixed tube 41, a sliding tube 42, a stirring assembly 43 and a support assembly 44; the fixed tube 41 is fixed in the movable shaft barrel 3, the sliding tube 42 is slidably connected to the fixed tube 41, the stirring assembly 43 is rotatably arranged in the sliding tube 42 and can pass through the extrusion plate 31, the driving assembly 5 is arranged on the sliding tube 42 and can drive the stirring assembly 43 to rotate; the support assembly 44 is elastic, one end of the support assembly 44 is connected to the extrusion plate 31, and the other end is connected to the sliding tube 42. (The elasticity of the support assembly 44 allows the stirring assembly 43 to remain in the movable shaft barrel 3 when the extrusion plate 31 squeezes the sewage, and the support assembly 44 can be compressed by the pushing assembly 9, thereby causing the sliding tube 42 to slide downward, thereby driving the stirring assembly 43 to pass through the extrusion plate 31. Preferably, the movable shaft barrel 3, the fixed tube 41 and the sliding tube 42 are all coaxially arranged.

[0034] In other embodiments, the support assembly 44 includes a support link 441, a support plate 442, and a support spring 443. The support plate 442 is connected to the sliding tube 42 via the support link 441. The support spring 443 is connected to the support plate 442 at one end and to the extrusion plate 31 at the other end. Preferably, the support plate 442 is an annular plate and is fixedly connected to the sliding tube 42 via multiple support links 441. Multiple support springs 443 are also provided to maintain the position of the sliding tube 42.

[0035] In other embodiments, the stirring assembly 43 includes a stirring shaft 431, a stirring plate 432 and a stirring gear ring 433; the stirring shaft is rotatably connected to the sliding tube 42, the stirring gear ring 433 is coaxially fixed on the stirring shaft 431, and the driving assembly 5 can drive the stirring gear ring 433 to rotate; the stirring plate 432 is fixed on the stirring shaft 431 near one end of the extrusion plate 31; the extrusion plate 31 is provided with an avoidance groove 32 corresponding to the stirring plate 432 and the stirring shaft 431, and the stirring shaft 431 and the stirring plate 432 can extend outward through the avoidance groove 32.

[0036] Specifically, one end of the sliding tube 42 is slidably connected to the fixed tube 41, and the other end is rotatably connected to the stirring shaft 431. The rotation of the stirring shaft 431 does not drive the rotation of the sliding tube 42, but the sliding of the sliding tube 42 drives the sliding of the stirring shaft 431. That is, an annular chute is provided within the sliding tube 42, and the stirring shaft 431 is connected to this annular chute via a slider. The size and shape of the avoidance groove 32 are the same as those of the stirring shaft 431 and the stirring plate 432. The side surfaces of the stirring shaft 431 and the stirring plate 432 abut against each other within the avoidance groove 32.

[0037] In other embodiments, the drive assembly 5 includes a drive link 51, a drive motor 52, and a drive gear 53. The drive link 51 is fixed to the sliding tube 42, the drive motor 52 is fixed to the drive link 51, and the drive gear 53 is coaxially fixed to the output shaft of the drive motor 52 and can drive the stirring assembly 43 to rotate. Specifically, the drive gear 53 is meshed with the stirring gear.

[0038] In other embodiments, the driven assembly 83 includes a driven connecting plate 81, a driven gear ring 82, and a driven assembly 83. The driven connecting plate 81 is fixed to the stirring mechanism 4, specifically, to the fixed tube 41. The driven gear ring 82 is rotatably connected to the driven connecting plate 81 and meshes with the first rack 6. The driven assembly 83 is rotatably mounted on the driven connecting plate 81 and is coaxial with the driven gear ring 82. The driven gear ring 82 is circumferentially provided with a plurality of ratchet teeth on its inner side and can unidirectionally drive the driven assembly 83 when the driven connecting plate 81 is raised. The rotation of the driven assembly 83 can cause the pusher assembly 9 to extend. That is, when the driven connecting plate 81 is lowered, the rotation of the driven gear ring 82 driven by the first rack 6 does not cause the driven assembly 83 to rotate. However, when the driven connecting plate 81 is raised, the rotation of the driven assembly 83 causes the pusher assembly 9 to extend.

[0039] In other embodiments, the driven assembly 83 includes a driven turntable 831, a driven shaft 832, a driven gear 833 and a pawl component 834; the driven turntable 831 is rotatably connected to the driven connecting plate 81 and is coaxial with the driven gear ring 82; the driven shaft 832 is coaxially fixed to the driven turntable 831, and the driven gear 833 is coaxially fixed to the driven shaft 832, and can drive the pushing assembly 9 to extend; the pawl component 834 is eccentrically arranged on the driven turntable 831, and the rotation of the driven gear ring 82 can drive the driven turntable 831 to rotate unidirectionally through the pawl component 834. That is, when the driven connecting plate 81 descends, the first rack 6 drives the driven gear ring 82 to rotate, and the inner ratchet of the driven gear ring 82 drives the pawl component 834 to rotate repeatedly without driving the driven turntable 831 to rotate; when the driven connecting plate 81 is lifted, the first rack 6 drives the driven gear ring 82 to rotate, and the inner ratchet of the driven gear ring 82 abuts the pawl component 834, and the pawl component 834 gives the driven turntable 831 a rotational force, causing the driven turntable 831 to rotate.

[0040] In other embodiments, the pawl component 834 includes a pawl coupling 8341, a torsion spring 8342, and a pawl body 8343. The pawl coupling 8341 is eccentrically mounted on the driven rotating disk 831, and the pawl body 8343 is rotatably mounted on the pawl coupling 8341 and connected to the driven rotating disk 831 via the torsion spring 8342. Specifically, when the driven connecting plate 81 descends, the inner ratchet teeth of the driven gear ring 82 drive the pawl body 8343 to rotate repeatedly. When the driven connecting rod ascends, the inner ratchet teeth of the driven gear ring 82 drive the pawl body 8343 to rotate along with the driven gear ring 82.

[0041] In other embodiments, the pushing assembly 9 includes a fixed sleeve 91, a second rack 92, and a pushing rod 93; the fixed sleeve 91 is fixed to the movable shaft barrel 3, the second rack 92 is slidably connected to the fixed sleeve 91, and the driven mechanism 8 can drive the second rack 92 to slide toward the extrusion plate 31; specifically, the second rack 92 is meshed with the driven gear 833. The pushing rod 93 is fixed to one end of the second rack 92 near the extrusion plate 31. It should be understood that a sliding groove is provided in the fixed sleeve 91, and the second rack 92 is slidably connected in the sliding groove. When the driven gear 833 is not rotating, the second rack 92 and the driven gear 833 are in a relatively static state, and the height position of the second rack 92 is limited by the friction between it and the fixed sleeve 91 and the support plate 442; when the driven gear 833 rotates, the second gear drives the driven rack to slide toward the extrusion plate 31.

[0042] In other embodiments, a waterproof pad 434 is further provided on the stirring plate 432 and the stirring shaft 431. The waterproof pad 434 is provided on the outer surface of the stirring plate 432 and the stirring shaft 431 to fill the gap between them and the avoidance groove 32, while increasing friction to prevent the stirring shaft 431 from moving vertically when squeezing the sewage.

[0043] The above-mentioned rapid solid content detection device can retract the stirring structure when squeezing sewage, and extend the stirring mechanism when lifting it up to stir, thereby squeezing more sewage.

[0044] It should be understood that the above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make some simple deductions or substitutions without departing from the concept of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the scope of protection of the present invention.
