Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a flocculant-based wastewater treatment device. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] There are many types of flocculants, ranging from low-molecular-weight to high-molecular-weight, and from single-component to composite types. The general trend is towards inexpensive, practical, non-toxic, and highly efficient flocculants. Inorganic flocculants are cheap, but they can have adverse effects on human health and the ecological environment. Although organic polymeric flocculants require less dosage, produce less scum, have strong flocculation ability, and facilitate floc separation, and are effective in removing oil and suspended solids, the residual monomers of these polymers have carcinogenic, mutagenic, and teratogenic effects, thus limiting their application.

[0004] Patent application number 202022334599.6 discloses a chemical wastewater treatment device using a decolorizing flocculant. When the wastewater reacts with the flocculant using a stirring rod, the device may throw out wastewater or precipitated flocculents during the stirring process, which may affect the surrounding environment. Furthermore, the wastewater can easily affect the stability of the device during stirring. Therefore, we propose a flocculant wastewater treatment device. Summary of the Invention

[0014] This invention provides a flocculant-based wastewater treatment device, which has the following beneficial effects:

[0015] (1) The present invention provides a flocculant wastewater treatment device. When the wastewater reacts with the flocculant through the treatment device, the wastewater or the precipitated flocculents are isolated by the wastewater treatment tank during the stirring process to prevent the wastewater and flocculents from being thrown out and affecting the surrounding environment. The outer wall of the wastewater treatment tank is fixedly connected by the first connecting block, thereby providing support for the wastewater treatment tank.

[0016] (2) The present invention is equipped with a sewage treatment tank. Sewage is injected into the sewage treatment tank through the inlet pipe. The sewage is treated by the treatment device and the flocculent matter is settled. The purified sewage is discharged through the outlet pipe. The sewage treatment tank isolates the sewage from the outside world and avoids splashing sewage from affecting the external environment.

[0017] (3) The present invention is equipped with a processing device. When the motor causes the rotating shaft to rotate, the first rotating rod flips outward along the first fixed block under the action of centrifugal force. When the first rotating rod flips, the first sliding block slides upward under the action of the first through hole. The stirring blades on the outer wall of the first rotating rod stir the sewage and flocculant in the sewage treatment tank, thereby increasing the reaction efficiency between sewage and flocculant.

[0018] (4) The present invention is provided with a first sliding block. When the motor stops rotating, the first rotating rod returns to its original position, and the first sliding block slides down along the first through hole through the second protrusion. The first sliding block separates the flocculent material and the sewage liquid, thereby facilitating the subsequent treatment of the sewage liquid. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Four casters 101 are fixedly connected to the bottom of the support plate 1, symmetrically arranged around the central axis of the support plate 1. A wastewater treatment tank 2 is fixedly connected to the axis of the support plate 1. The inner wall of the wastewater treatment tank 2 is cylindrical; the curved inner wall reduces the impact of wastewater on the inner wall. This invention, by providing the wastewater treatment tank 2, injects wastewater into the wastewater treatment tank 2 through an inlet pipe 202, and treats the wastewater using a treatment device 3 to produce flocculants. After sedimentation, the purified wastewater is discharged through the outlet pipe 201.

A support block 103 is fixedly connected to the top of the support plate 1. The system also includes:

[0029] The treatment device 3 includes a motor 301 fixedly connected to the sewage treatment tank 2. The motor 301 passes through the sewage treatment tank 2 and is fixedly connected to a rotating shaft 3011. A first fixing block 3012 is fixedly connected to one end of the rotating shaft 3011 near the motor 301, and a second fixing block 3013 is fixedly connected to the other end of the rotating shaft 3011 away from the motor 301. A first rotating rod 302 is rotatably connected to the inner wall of the first fixing block 3012 via a rotating shaft. A first sliding block 3024 is provided on the outer wall of the first rotating rod 302. The outer wall of the first connecting block 4 is slidably connected to the inner wall of the sewage treatment tank 2. The outer wall of the second fixing block 3013 is provided with a third sliding block 304. This invention provides a flocculant sewage treatment device. When the sewage reacts with the flocculant through the treatment device 3, the sewage treatment tank 2 will isolate the sewage or the precipitated flocculent during the stirring process, so as to prevent the sewage and flocculent from being thrown out and affecting the surrounding environment. The first connecting block 102 is fixedly connected to the outer wall of the sewage treatment tank 2, thereby providing support for the sewage treatment tank 2.

[0030] The top outer wall of the sewage treatment tank 2 is fixedly connected to an outlet pipe 201, which is used to discharge the treated sewage and input the flocculant. The bottom outer wall of the sewage treatment tank 2 is fixedly connected to an inlet pipe 202, which is used to transport sewage to the sewage treatment tank 2 and discharge flocculents. The outer wall of the sewage treatment tank 2 is fixedly connected to a first fixing ring 203, and the inner wall of the sewage treatment tank 2 is slidably connected to a first sliding block 3024.

[0031] The bottom outer wall of the first fixing ring 203 is fixedly connected to a second connecting block 2031 via a rotating shaft. There are three second connecting blocks 2031, which are symmetrically arranged with the central axis of the first fixing ring 203 as the center. The left outer wall of the second connecting block 2031 is fixedly connected to a fixing shaft 2032. There are two fixing shafts 2032, which are symmetrically arranged with the central axis of the second connecting block 2031 as the center.

[0032] The outer wall of the fixed shaft 2032 is slidably connected to the support block 103. A first spring 2033 is fixedly connected to the left outer wall of the fixed shaft 2032. The end of the first spring 2033 away from the fixed shaft 2032 is fixedly connected to the support block 103. The first spring 2033 is used to dampen the sewage treatment tank 2.

[0033] The working principle of this embodiment is as follows: sewage is injected into the sewage treatment tank 2 through the inlet pipe 202, and flocculant is injected into the inner wall of the sewage treatment tank 2 through the outlet pipe 201. The sewage and flocculant are stirred and treated by the treatment device 3. After stirring is completed, the flocculent and liquid are separated by sedimentation. During the operation of the treatment device 3, the sewage treatment tank 2 is fixedly connected to the outer wall by the first fixing ring 203. The fixing shaft 2032 of the outer wall of the first fixing ring 203 slides with the support block 103. The first spring 2033 dampens the sewage treatment tank 2 and prevents the sewage treatment tank 2 from shaking violently during the operation.

[0034] Example 2: Please refer to Figures 4-7 Based on Embodiment 1, the present invention provides a technical solution: the number of first rotating rods 302 is three, the three first rotating rods 302 are symmetrically arranged with the motor 301 as the center, the inner wall of the first rotating rod 302 is provided with a first through hole 3021, the left outer wall of the first rotating rod 302 is fixedly connected with a stirring blade 3022, the stirring blade 3022 is used to increase the reaction rate between sewage and flocculant, and the bottom of the first rotating rod 302 is fixedly connected with a first arc-shaped rod 3023.

[0035] The right inner wall of the stirring blade 3022 is rotatably connected to a second rotating rod 3028 via a rotating shaft. A second sliding block 303 is provided at the end of the second rotating rod 3028 away from the first rotating rod 302. The inner wall of the second sliding block 303 is rotatably connected to the second rotating rod 3028 via a rotating shaft. The second sliding block 303 slides according to the rotation of the first rotating rod 302. The inner wall of the second sliding block 303 is slidably connected to the rotating shaft 3011.

[0036] The inner wall of the first sliding block 3024 is provided with three second through holes 3025, which are symmetrically arranged around the central axis of the first sliding block 3024. The inner wall of the first sliding block 3024 is provided with filter holes 3026, which are used to separate flocculent matter from the purified liquid. A second protrusion 3027 is fixedly connected to the bottom of the first sliding block 3024. The inner wall of the second protrusion 3027 is slidably connected to the first through hole 3021 via a rotating shaft. This invention, by providing a processing device 3, allows the first rotating rod 302 to move along the first fixed shaft 3011 under the action of centrifugal force when the motor 301 causes the rotating shaft 3011 to rotate. The fixed block 3012 flips outward. When the first rotating rod 302 flips, the first sliding block 3024 slides upward under the action of the first through hole 3021. The stirring blades 3022 on the outer wall of the first rotating rod 302 stir the sewage and flocculant in the sewage treatment tank 2, thereby increasing the reaction efficiency between the sewage and the flocculant. In this invention, by setting the first sliding block 3024, when the motor 301 stops rotating and the first rotating rod 302 returns to its position, the first sliding block 3024 slides downward along the first through hole 3021 through the second protrusion 3027. The first sliding block 3024 separates the flocculent and the sewage liquid, thereby facilitating the subsequent treatment of the sewage liquid.

[0037] There are three third sliding blocks 304, which are symmetrically arranged around the sewage treatment tank 2. Two connecting rods 3042 are fixedly connected to the top outer wall of the third sliding block 304, which are symmetrically arranged around the third sliding block 304. A second spring 3041 is fixedly connected to the back of the third sliding block 304. The end of the second spring 3041 away from the third sliding block 304 is fixedly connected to the second fixed block 3013. A second arc-shaped rod 3043 is rotatably connected to the inner wall of the third sliding block 304 through a rotating shaft. The second arc-shaped rod 3043 can gather the precipitated flocculent matter, making it easier to pull out from the inlet pipe 202. There are two second arc-shaped rods 3043, which are symmetrically arranged around the third sliding block 304.

[0038] The working principle of this embodiment is as follows: The motor 301 rotates the rotating shaft 3011, which causes the first rotating rod 302 to flip outward along the first fixed block 3012. The stirring blades 3022 on the outer wall of the first rotating rod 302 stir the sewage inside the sewage treatment tank 2. When the first rotating rod 302 rotates, the second sliding block 303 slides upward along the rotating shaft 3011 under the action of the first rotating rod 302 flipping outward. After stirring is completed, the motor 301 stops rotating, and the first sliding block 3024 slides along the first through hole 3021. The first sliding block 3024 separates the flocculent material and the purified sewage through the filter hole 3026, thereby accelerating the sedimentation of the flocculent material. When the first rotating rod 302 resets, it pushes the third sliding block 304, which causes the second arc-shaped rod 3043 to gather the flocculent material, thereby facilitating the discharge of the flocculent material.
