Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to a small-scale domestic sewage treatment device with a flocculent impurity collection function. Background Art

[0002] Small-scale domestic sewage treatment equipment is usually used for sewage treatment in households, small communities or commercial places. These equipment usually include biological treatment systems, sedimentation tanks, filters and other components. They remove harmful substances in sewage through physical, chemical and biological treatment methods to meet emission standards. Small-scale domestic sewage treatment equipment is usually simpler and more economical than traditional centralized sewage treatment plants. It is suitable for areas without access to public sewer systems or users who need to treat sewage independently.

[0003] In the prior art, small-scale domestic sewage treatment equipment generally includes components such as a screen scrubber, a sedimentation tank, and a biochemical tank. The screen scrubber is mainly used to remove solid impurities and large particles in the water, which belongs to the category of mechanical filtration. The screen scrubber can effectively collect and remove suspended particles and solid particles, but cannot process fine particles or dissolved matter and flocculent substances in the liquid. Therefore, although the screen scrubber in the small-scale domestic sewage treatment equipment can collect some flocculent impurities, it is not its main function and cannot efficiently remove flocculent impurities in domestic sewage. During sewage treatment, the presence of floccules will accumulate and settle in the sewage treatment equipment and pipelines, causing blockage of the equipment and pipelines, reducing treatment efficiency, and hindering processes such as biodegradation and chemical coagulation in the sewage treatment process, thereby affecting the sewage treatment effect and water purification effect.

[0004] In addition, flocs are composed of fine particles and suspended matter in sewage, including grease, protein suspended particles, etc., and if the flocs are not collected and treated during sewage treatment, the flocs will settle and accumulate at the bottom of the sewage treatment device, and gradually block the outlet at the bottom of the equipment, making it difficult to discharge wastewater, affecting the normal operation of the equipment, and reducing the effective volume inside the equipment, affecting the full mixing of wastewater and flocculants, thereby reducing the sewage treatment efficiency. The deposition of flocs will further accelerate the corrosion and damage of the bottom of the equipment, increasing the maintenance cost and repair frequency of the equipment.

[0005] Therefore, a small domestic sewage treatment equipment with flocculent impurity collection function is proposed to solve the above problems. Summary of the Invention

[0016] Compared with the prior art, the present invention provides a small-scale domestic sewage treatment equipment with a flocculent impurity collection function, which has the following beneficial effects:

[0017] 1. By setting up the flocculent impurity sedimentation mechanism, the flocculant is added to the sewage in batches when the sewage is stirred, thereby improving the uniformity of the mixing of the flocculant and the sewage, ensuring the formation of a uniform flocculant concentration in the sewage, better agglomerating the flocculent impurities in the sewage, and improving the sedimentation efficiency of the flocculent impurities.

[0019] 3. By setting up the cleaning brush, the filter can be cleaned at the same time as the clumped flocculent impurities are collected to prevent the flocculent impurities from adhering to the mesh surface of the filter when they are deposited, causing the filter to be blocked, resulting in difficulty in discharging the treated sewage in the sedimentation barrel, thereby affecting the normal operation of the equipment. Cleaning the filter can effectively improve the internal discharge efficiency and effective volume of the equipment, improve the smoothness of the equipment operation, further prevent the presence of fine flocculent impurities from corroding and damaging the bottom of the equipment, reduce the maintenance cost and repair frequency of the equipment, and prevent the inconvenience caused by equipment damage and repair on the discharge of sewage in the living area.

[0020] 4. Through the coordinated use of the Hall switch and the magnetic block, after the sector-shaped storage box and the sector-shaped adapter box continuously collect flocculent impurities, when the volume of the internal flocculent impurities is too large, the magnetic block approaches the Hall switch and triggers the Hall switch, thereby activating the external alarm device, prompting the operator that the flocculent impurities collected during internal sewage treatment exceed the standard and need to be removed for treatment to maintain the operation of the equipment. In this way, the volume of the internal flocculent impurities can be monitored, the frequency of manual inspections and interventions can be reduced, and labor costs can be saved.

[0041] Wherein: flocculant is placed in the storage barrel 208.

[0042] Further examples: Please refer to Figures 6 to 9 As shown:

[0043] The impurity collection monitoring mechanism 3 is used to collect and process the flocculent clumps deposited at the bottom and then remind the operator to clean it according to the volume of the collected flocculent clumps. The impurity collection monitoring mechanism 3 includes a fan-shaped storage box 301. The fan-shaped storage box 301 is used in conjunction with the fan-shaped adapter box 303 to collect the deposited flocculant clumps. The fan-shaped storage box 301 is fixedly connected to the bottom of the inner cavity of the sedimentation barrel 201. An inner groove is provided in the middle of one side of the curved surface of the fan-shaped storage box 301. A Hall switch 302 is fixedly connected to the inner groove of the fan-shaped storage box 301. The Hall switch 302 is electrically connected to an external alarm device.

A plurality of filter holes 304 are provided on a side of the fan-shaped adapter box 303 perpendicular to the filter 202. An inner groove is provided in the middle of a side of the fan-shaped adapter box 303 perpendicular to the filter 202. A magnetic block 305 is fixedly connected to the inner groove of the fan-shaped adapter box 303. The magnetic block 305 is triggered when it is kept close to the Hall switch 302 for a long time. The position of the magnetic block 305 corresponds to the Hall switch 302. The fan-shaped storage box 301 is snap-fitted to the fan-shaped adapter box 303. The fan-shaped adapter box 303 is connected to a built-in power supply. A cleaning brush 306 is fixedly connected to the side of the fan-shaped adapter box 303 with the filter holes 304. The cleaning brush 306 is mainly used for rotating and cleaning the filter 202.

[0044] Wherein: the fan-shaped storage box 301 and the fan-shaped adapter box 303 are connected to form a complete fan-shaped closed box.

[0045] Everything in the above example works as follows:

[0046] In the initial state: sewage enters the sedimentation barrel 201 through the water inlet pipe 102, flocculant is placed in the storage barrel 208, the bidirectional motor 204 is not started, and cannot drive the column 205 and the stirring rod 218 to rotate, the fan-shaped adapter box 303 is on the side of the fan-shaped storage box 301 where the baffle is provided and is not in contact with the fan-shaped storage box 301, the auxiliary pipe 220 seals the filter screen 202 to prevent the sewage in the sedimentation barrel 201 from leaking through the outlet pipe 103, and the friction column 214 and the groove on the circular arc block 215 are in a symmetrical position.

[0047] The following is the working process of the flocculent impurity deposition mechanism 2, which condenses the floccules in the sewage into agglomerates and deposits them at the bottom through the action of the administered agent:

[0048] During use, the sewage after upper treatment is poured into the sedimentation barrel 201 through the water inlet pipe 102. After the sewage in the sedimentation barrel 201 accumulates to a certain water level, the sedimentation barrel 201 transmits the water level signal to the external controller through the water level detector of the internal device. At this time, the bidirectional motor 204 is started by the program set by the external controller, driving the driving column 205 at the upper end to rotate clockwise. When the driving column 205 rotates clockwise, the synchronous plate 206 is synchronously driven to rotate clockwise. Since the synchronous plate 206 is fixedly connected to the driving column 205, the lifting plate 211 maintains the same rotational motion with the driving column 205 through the adjusting column 209. Therefore, when the driving column 205 rotates clockwise, the lifting plate 211 and the driving column 205 maintain the same rotational motion. When the step plate 206 drives the first discharge pipe 207 to rotate clockwise, the lifting plate 211 and the second discharge pipe 212 rotate clockwise synchronously following the driving column 205. At the same time, since the storage barrel 208 is kept fixed in position with the sedimentation tank 1 through the opening and closing cover 101, when the synchronous plate 206 moves, the synchronous plate 206 drives the first discharge pipe 207 and the storage barrel 208 to gradually separate. The plate surface of the synchronous plate 206 blocks the discharge port of the storage barrel 208 to prevent the flocculant from leaking. The quantitative flocculant is stored in the first discharge pipe 207 and the second discharge pipe 212. Then, when the second discharge pipe 212 rotates, it drives the opening and closing plate through the auxiliary block provided on its side. 213 and the second feeding tube 212 maintain the same speed, and then the rotation of the opening and closing plate 213 drives the contact column 214 to rotate synchronously around the driving column 205. During the rotation of the contact column 214, the circular arc block 215 is relatively fixed with the bidirectional motor 204 through the L-type buckling ring body 216 and the telescopic rod 217, and the circular groove 210 rotates with the rotation of the adjusting column 209. Therefore, when the contact column 214 rotates clockwise, the contact column 214 slides on the lower surface of the circular arc block 215 and gradually approaches the groove provided on the circular arc block 215. When the contact column 214 slides into the groove of the circular arc block 215, due to the height difference between the groove and the plane of the circular arc block 215, the contact column 214 is rotated. The difference in degree causes the interference column 214 to deflect upward, thereby causing the opening and closing plate 213 to deflect downward with the middle portion as a fulcrum, thereby opening the discharge port of the second discharge pipe 212, so that the flocculant stored in the first discharge pipe 207 and the second discharge pipe 212 falls into the sewage in the sedimentation bucket 201 and mixes with the sewage. After the driving column 205 continues to rotate, the interference column 214 slides out of the groove, and the opening and closing plate 213 blocks the second discharge pipe 212. At the same time, the first discharge pipe 207 gradually approaches the storage bucket 208 until they are attached. At this time, the flocculant in the storage bucket 208 continues to be fed into the cavities of the first discharge pipe 207 and the second discharge pipe 212 for storage.

[0049] During the flocculant addition process, the bidirectional motor 204 synchronously drives the stirring rod 218 at the lower end to rotate. The rotation of the stirring rod 218 drives the stirring column 219 to rotate synchronously. Under the action of the multiple branch rods of the stirring column 219, the flocculant is broken up and better mixed with the sewage, thereby collecting and treating flocculent impurities in the sewage on a larger scale.

[0050] By setting up the flocculent impurity deposition mechanism 2, the flocculant components are added to the sewage in batches when the sewage is stirred, thereby improving the uniformity of the mixing of the flocculant and the sewage, ensuring the formation of a uniform flocculant concentration in the sewage, better agglomerating the flocculent impurities in the sewage, and improving the sedimentation efficiency of the flocculent impurities. At the same time, adding the flocculant in batches can reduce the time for the flocculant to mix with the flocculent impurities in the sewage, thereby improving the sewage treatment efficiency and saving treatment time and energy.

[0051] Please refer to the above working process Figures 1 to 6 .

[0052] The following is the working process of the impurity collection and monitoring mechanism 3 for collecting and processing the floccules deposited at the bottom and then reminding the operator to perform cleaning processing according to the volume of the collected floccules:

[0053] During use, after the flocculant is added into the sewage for stirring, the flocculent impurities gather into clumps under the action of the flocculant, and then settle to the bottom of the sedimentation barrel 201 under the influence of gravity and are placed on the filter screen 202. After the flocculent impurities are clumped and deposited, the fan-shaped adapter box 303 is started by the externally connected controller, driving the fan-shaped adapter box 303 to rotate clockwise around the storage barrel 208, gradually approaching the fan-shaped storage box 301, and in the process of the rotation of the fan-shaped adapter box 303, under the action of the side baffle and the upper baffle of the fan-shaped adapter box 303, the filter screen 202 is simultaneously settled. The accumulated flocculent clumps are collected, and in the process that the fan-shaped adapter box 303 gradually approaches the fan-shaped storage box 301, the fan-shaped adapter box 303 rotates around the filter screen 202, and then approaches the fan-shaped storage box 301 until it fits together, forming a sealed cavity with the fan-shaped storage box 301. Under the action of the filter holes 304, the flocculent clumps installed in the fan-shaped adapter box 303 are in the sewage, and when the fan-shaped adapter box 303 drives the flocculent clumps to approach the fan-shaped storage box 301, the two side baffles of the fan-shaped storage box 301 and the fan-shaped adapter box 303 gradually approach each other, squeezing the flocculent clumps. The fan-shaped adapter box 303 is pressed inside, and the water in the flocculent mass is squeezed out through the filter hole 304. When the fan-shaped adapter box 303 and the fan-shaped storage box 301 form a cavity, the volume feedback is performed after the water is squeezed out of the flocculent mass inside the device. Then, the fan-shaped adapter box 303 is driven by the external controller to rotate counterclockwise to reset. After multiple sewage treatments, the fan-shaped adapter box 303 rotates clockwise to collect the flocculent mass deposited on the filter screen 202. If the volume of the flocculent mass is too large, the fan-shaped adapter box 303 moves toward the fan when it is close to the fan storage box 301 for collection. The fan-shaped storage box 301 continues to approach, but because the flocculent mass inside is too large, the approach of the fan-shaped adapter box 303 and the fan-shaped storage box 301 is blocked by the larger flocculent mass. The flocculent mass cannot be compressed by the fan-shaped adapter box 303 when it approaches. As a result, the magnetic block 305 on the fan-shaped adapter box 303 and the Hall switch 302 on the fan-shaped storage box 301 approach each other and stay there for too long, causing the Hall switch 302 to be triggered. The external alarm device connected to the Hall switch 302 is activated, prompting the operator that the internal flocculent impurities have exceeded the standard and need to be removed for treatment.

[0054] At the same time, as the sector-shaped adapter box 303 rotates around the storage barrel 208 and approaches the sector-shaped storage box 301, the cleaning brush 306 on the side of the sector-shaped adapter box 303 away from the sector-shaped storage box 301 simultaneously scrapes and cleans the mesh surface of the filter 202 under the action of the rotation of the sector-shaped adapter box 303, preventing small unagglomerated flocs from adhering to the filter 202 and affecting the sewage treated in the sedimentation barrel 201 from reaching the downward operation pool through the auxiliary pipe 220 and the outlet pipe 103;

[0055] By setting up the impurity collection and monitoring mechanism 3, after the flocculent impurities are clumped and deposited on the bottom filter screen 202, the fan-shaped adapter box 303 moves around the filter screen 202 and is used in conjunction with the fan-shaped storage box 301 to collect and process the flocculent impurities multiple times, effectively reducing the suspended solid content in the water during sewage treatment, improving water quality, reducing water turbidity, and further reducing the impact of the presence of flocculent impurities on pipe blockage in the equipment, improving sewage treatment efficiency, and improving processes such as biodegradation and chemical coagulation during sewage treatment, thereby improving sewage treatment effects and water purification effects.

[0056] By setting the cleaning brush 306, the filter 202 is cleaned while collecting the clumped flocculent impurities, so as to prevent the flocculent impurities from adhering to the mesh surface of the filter 202 when deposited, causing the filter 202 to be blocked, resulting in difficulty in discharging the treated sewage in the sedimentation barrel 201, thereby affecting the normal operation of the equipment. Cleaning the filter 202 can effectively improve the discharge efficiency and effective volume inside the equipment, improve the smoothness of the equipment operation, further prevent the presence of fine flocculent impurities from corroding and damaging the bottom of the equipment, reduce the maintenance cost and repair frequency of the equipment, and prevent the damage and repair of the equipment from causing inconvenience to the discharge of sewage in the living area.

[0057] Through the coordinated use of the Hall switch 302 and the magnetic block 305, after the sector-shaped storage box 301 and the sector-shaped adapter box 303 continuously collect flocculent impurities, when the volume of the internal flocculent impurities is too large, the magnetic block 305 approaches the Hall switch 302 and triggers the Hall switch 302, thereby activating the external alarm device, prompting the operator that the flocculent impurities collected during internal sewage treatment exceed the standard and need to be removed for treatment to maintain the operation of the equipment. In this way, the volume of the internal flocculent impurities can be monitored, the frequency of manual inspections and interventions can be reduced, and labor costs can be saved.
