Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment equipment, and in particular relates to an automatic sewage treatment equipment for sewage treatment. Background Art

[0002] Wastewater treatment generally includes a pretreatment step to remove large solids and suspended matter, a biological treatment step using microorganisms to break down organic matter in the wastewater, a sedimentation step, an advanced treatment step, and a disinfection step. Advanced treatment generally refers to chemical precipitation through the addition of flocculants.

[0003] Depending on the scale of sewage treatment, chemical precipitation is generally carried out in a flocculation tank or flocculation box. Coagulants and flocculants are added to the flocculation box. After the sewage is fully mixed with the coagulant and flocculant, the particles in the sewage that are difficult to precipitate aggregate with each other to form colloids, and combine with impurities in the water to form larger flocs. The flocs have strong adsorption capacity and can not only adsorb suspended matter, but also some bacteria and soluble substances. Through adsorption, the flocs increase in volume and sink, forming precipitation in the flocculation box.

[0004] After searching, the patent document with publication number CN118289914 A discloses a sewage treatment equipment, which drives the filter plate into the flocculation box and moves toward the filter frame through a driving component, pushing the flocculants and collecting them in the filter frame; when the filter plate moves to conflict with the filter frame, the fixing component fixes the filter plate and the filter frame, and all the flocculants are collected and stored in the filter frame. The filter frame is driven by the driving component to move outside the flocculation box, thereby taking out the sediment in the flocculation box, thereby facilitating the cleaning of the sediment in the flocculation box.

[0005] When the filter frame and filter plate rise with the multi-stage electric cylinder, they need to stay above the flocculation box and drain the water. Since the agglomerated sediment contains water and the sediment is only placed inside the filter frame, it takes a long time to drain the water naturally, resulting in low sewage treatment efficiency.

[0010] As an optimal technical solution, a ball head rod is welded on the curved outer wall of the positioning plate at the vacant positions of the two groups of second support arms. There are three groups of positioning plates, which are distributed in a circular shape with equal intervals on the outer wall of the positioning plate. A spiral guide groove extending to the top of the cylinder is provided at the contact position between the inner wall of the cylinder and the end of the ball head rod.

[0011] As an optimal technical solution, multiple groups of the fan-shaped frames and lining fan plates form a retractable annular filter cartridge at the top of the second support arm, and a giveway groove connected to the accommodating groove is provided at the top of each group of the fan-shaped frames, and the inner two side curved surfaces of the giveway groove are fixed with arc-shaped elastic parts.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention can quickly collect flocculated sediments in the water body through the mutual cooperation of the plugging component and the dewatering component. The sediments settled in the cylinder can be quickly taken out by the rising of the screw rod. The rising will drive the plugging component and the dewatering component to contract radially, so that the sediments inside the dewatering component flow to the lowest depression. The sediments will be squeezed out of the internal water by the shrinking deformation force, thereby accelerating the dehydration of the sediments and facilitating the removal of the sediments, thereby improving the sewage treatment efficiency.

[0019] The present invention reduces the contact area between the cross section of the dewatering assembly and the water by radially contracting the dewatering assembly, thereby reducing the resistance generated by the water when the dewatering assembly rises in the cylinder, reducing the height of the water splash, thereby preventing the water from splashing in the cylinder, and reducing the workload of the electric push rod, thereby extending its service life.

[0020] The dewatering assembly of the present invention is provided with a ball head rod. When the ball head rod rises straight upward in the cylinder, it slides along the spiral guide groove track provided on the inner wall, driving the dewatering assembly to rotate around the central axis of the screw rod, generating a certain centrifugal effect on the sediment in the shrunken dewatering assembly, and can throw out the water inside the sediment, thereby accelerating the drainage of the water inside the sediment and facilitating the removal of the sediment.

DETAILED DESCRIPTION

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0032] The following describes an embodiment of the present invention based on its overall structure.

[0033] An automated sewage treatment equipment for sewage treatment, such as Figures 1 to 9 As shown, it includes a cylinder 100, a transmission screw assembly 400 for stirring sewage is longitudinally assembled at the center position of the cylinder 100, and the transmission screw assembly 400 includes a screw 410 rotatably arranged in the cylinder 100, a notch 420 is opened on the curved outer wall of the screw 410, and three sets of stirring arms 430 are rotatably arranged in the notch 420. A drive motor 140 for driving the screw 410 to rotate is installed on the top of the screw 410, and a water removal assembly 300 placed at the bottom of the cylinder 100 is connected to the bottom of the screw 410. The outer wall of the screw 410 is threadedly connected to the plugging assembly 200;

[0034] The dewatering assembly 300 includes a positioning plate 350 assembled on the bottom of the cylinder 100, and the curved outer wall of the positioning plate 350 is rotatably connected to multiple groups of second support arms 310. The top of the positioning plate 350 is fixed with a lining restraining rod 360 that slides in the bottom of the screw rod 410. The end of each group of second support arms 310 away from the positioning plate 350 is rotatably provided with a fan-shaped frame 330. The fan-shaped frame 330 is located on the upper surface of the second support arm 310. A second fan-shaped filter screen 320 is fixed between two adjacent groups of second support arms 310. The end of the second fan-shaped filter screen 320 extends to the curved outer wall position of the fan-shaped frame 330. A lining fan plate 340 is slidably assembled between two adjacent groups of fan-shaped frames 330. Both ends of each group of fan-shaped frames 330 are provided with a receiving groove 333 for the lining fan plate 340 to enter and exit.

[0035] The plugging assembly 200 includes a driven sleeve 210 threadedly sleeved on the outer wall of the screw rod 410. The curved outer wall of the driven sleeve 210 is rotatably connected to multiple sets of first support arms 220. A first sector-shaped filter screen 230 is installed between two adjacent sets of first support arms 220. The multiple sets of first sector-shaped filter screens 230 and the first support arms 220 form a disc-shaped filter screen.

[0036] The curved outer wall of the positioning plate 350 is welded with a ball head rod 351 at the vacant position of the two groups of second support arms 310. There are three groups of positioning plates 350, which are distributed in a circular shape with equal intervals on the outer wall of the positioning plate 350. A spiral guide groove 160 extending to the top of the cylinder 100 is provided at the contact position between the inner wall of the cylinder 100 and the end of the ball head rod 351.

[0037] The sewage to be treated is fed into the cylinder 100, and a coagulant and a coagulant aid are added from the top of the cylinder 100. Then, the drive motor 140 is started. The output end of the drive motor 140 drives the screw 410 and the stirring arm 430 to rotate, so that the sewage, the coagulant and the coagulant aid are fully mixed until the reaction produces flocculated sediment.

[0038] When the screw rod 410 rotates and stirs the sewage, coagulant and coagulant aid, the blocking component 200 will descend along the outer wall of the screw rod 410 into the cylinder 100 due to the action of the restraining slats 260. Since the first sector-shaped filter screen 230 will block the flocculent sediment floating in the sewage and on the surface of the sewage, as the first sector-shaped filter screen 230 approaches the dewatering component 300, when the blocking component 200 and the dewatering component 300 are fitted, the arc groove clamp 250 at the bottom of the rotating shaft 240 will extend into the give way groove 332 and squeeze the arc-shaped elastic member 370 toward both sides to deform in the inward and outward directions, allowing the arc groove clamp 250 to descend completely The water pump 200 is put into the water pump 200, and the water pump 200 is put into the water pump 200. The water pump 200 is put into the water pump 200, and the water pump 200 is put into the water pump 200. The water pump 200 is put into the water pump 200, and the water pump 200 is put into the water pump 200. The water pump 200 is put into the water pump 200, and the water pump 200 is put into the water pump 200. The water pump 200 is put into the water pump 200, and the water pump 200 is put into the water pump 200. The water pump 200 is put into the water pump 200, and the water pump 200 is put into the water pump 200. The water pump 200 is put into the water pump 200, and the water pump 200 is put into the water pump 200. The water pump 200 is put into the water pump 200, and the water pump 200 is put into the water pump 200. 20 rotates downward, at this time the first support arm 220 rotates downward around the connection point with the driven sleeve 210, and at the same time the second support arm 310 rotates upward around the connection point with the positioning plate 350, and the fan-shaped frames 330 at the tops of the two adjacent groups of second support arms 310 gradually approach each other, that is, the lining fan plate 340 enters the fan-shaped frames 330 on both sides. Due to the constraint of the arc-shaped elastic member 370, the lining fan plate 340 enters the receiving groove 333 according to the preset track, so that the cross section of the cylindrical dewatering component 300 is reduced, and the inner bottom of the dewatering component 300 and the blocking component 200 are both conical. At this time, the first fan-shaped filter screen 230 and the second fan-shaped filter screen The filter screen 320 changes from a right angle to an obtuse angle, and at the same time, it approaches the middle and becomes wavy, providing space for the first support arm 220 and the second support arm 310 to rotate close to the screw 410. The flocculated sediment inside the dewatering assembly 300 is concentrated at the pointed cone inside the dewatering assembly 300. When the screw 410 rises to the upper limit, it drives the dewatering assembly 300, which has been deformed and shrunk, to rise through the lining constraint rod 360, thereby driving the dewatering assembly 300 to rise until it is separated from the water inside the cylinder 100. At this time, the angles between the multiple sets of second support arms 310 and the screw 410 are acute, and the sediment is squeezed to drain the water inside.

[0039] As the dewatering assembly 300 and the sealing assembly 200 shrink, the restraining strip 260 disengages from the restraining groove 170, and the ball head rod 351 rises together with the positioning plate 350 under the traction of the screw rod 410. The ball head rod 351 will slide along the inner wall of the spiral guide groove 160, causing the shrunken dewatering assembly 300 to rotate at the bottom of the sealing assembly 200 with the axis of the screw rod 410 as the center. Under the obstruction of the water body inside the cylinder 100, the sediment can be driven to concentrate in the lowest depression in the dewatering assembly 300 (the inner conical surface of the shrunken dewatering assembly 300) so as to squeeze out the water inside the sediment. When the dewatering assembly 300 is separated from the water body in the cylinder 100, the shrunken dewatering assembly 300 will be driven to generate a certain centrifugal force, which can accelerate the dehydration of the sediment inside the dewatering assembly 300, improve the drainage effect of the dewatering assembly 300, facilitate the removal of the sediment, and thus improve the sewage treatment efficiency.

[0040] Please refer to Figures 3 to 7 The top of the first support arm 220 is provided with a rotating shaft 240, and the top of the rotating shaft 240 is fixed with a rotating shaft 240.

[0041] The annular elastic member forms an annular track in the clearance groove 332 opened on the top of the multiple sets of fan-shaped frames 330.

[0042] The inner lining fan plate 340 plays a guiding and restraining role. When the multiple sets of fan-shaped frames 330 are retracted, the inner lining fan plate 340 can slide into the accommodating groove 333 along the annular track, and the arc groove clamping member 250 at the bottom of the first support arm 220 can enter the space between the two sets of arc-shaped elastic members 370 in multiple directions, thereby facilitating the engagement of the sealing assembly 200 and the water removal assembly 300.

[0043] At the same time, the blocking component 200 and the dewatering component 300 are connected by a circular track and a plurality of arc-shaped elastic members 370 . The dewatering component 300 can rotate at the bottom of the blocking component 200 to accelerate the discharge of water inside the dewatering component 300 .

[0044] Please refer to Figure 1 and Figure 3A drive motor 140 is installed on the top of the screw rod 410, and a beam 120 for fixing the drive motor 140 is sleeved on the outside of the output end of the drive motor 140. A multi-stage electric push rod 110 for driving the beam 120 to rise and fall is installed on one side of the cylinder 100. A base plate 130 is fixed to the bottom of the multi-stage electric push rod 110, and the cylinder 100 is fixed to the top of the base plate 130.

[0045] The drive motor 140 is started, and the output end of the drive motor 140 drives the screw 410 to rotate, so that the sewage in the cylinder 100 is mixed with the coagulant and the coagulant aid, so that the dirt in the sewage is flocculated and precipitated;

[0046] The multi-stage electric push rod 110 can drive the driving motor 140 and the screw rod 410 to rise through the crossbeam 120, and cooperate with the water removal component 300 to remove the sediment deposited in the cylinder 100.

[0047] Please refer to Figure 2 and Figure 9 The inner wall of the cylinder 100 is symmetrically provided with constraint grooves 170 in the longitudinal direction. The depth of the constraint grooves 170 is less than the depth of the spiral guide grooves 160. The tops of the two groups of constraint grooves 170 extend to the upper surface of the cylinder 100. A constraint frame 150 is fixed to the upper surface of the cylinder 100 at a position corresponding to each group of constraint grooves 170.

[0048] Constraint strips 260 are fixed to the tops of the two groups of first support arms 220 , and the ends of the constraint strips 260 extend into the constraining frame 150 .

[0049] The restraining groove 170 and the restraining strip 260 cooperate with each other so that when the screw rod 410 rotates, the driven sleeve 210 will be lowered linearly along the outer wall of the screw rod 410, and finally the plugging assembly 200 will contact and lock the water removal assembly 300 located in the cylinder 100. With the assistance of the restraining frame 150, the driven sleeve 210 located above the cylinder 100 can also be raised and lowered linearly.

[0050] The depth of the constraint groove 170 opened in the inner wall of the cylinder 100 is less than the depth of the spiral guide groove 160. When the ball head rod 351 slides along the spiral guide groove 160 and passes through the constraint groove 170, it will not deviate into the constraint groove 170, so that the ball head rod 351 can spirally rise along the spiral guide groove 160.

[0051] Please refer to Figure 2 and Figure 4 Arc-shaped notches 331 are provided at the upper and lower ends of each set of fan-shaped frames 330 and near the outer wall. The upper and lower sets of arc-shaped notches 331 can be used for the ends of the second fan-shaped filter 320 and the first fan-shaped filter 230 to enter. The outer walls of each set of second fan-shaped filter 320 and the first fan-shaped filter 230 are provided with curved portions.

[0052] The arc-shaped notch 331 allows the ends of the L-shaped second fan-shaped filter 320 and the first fan-shaped filter 230 to be wrapped around the outer wall of the fan-shaped frame 330, thereby compensating for the gaps generated when the dewatering component 300 is deformed, preventing the sediment in the dewatering component 300 from leaking from the gaps, and ensuring the high quality of the water in the cylinder 100.

[0053] Please refer to Figure 2 and Figure 8 The stirring arm 430 is rotatably connected to the notch 420 through the damping shaft. The front surface of the notch 420 is inlaid with a magnet 440 at the bottom position of each group near the stirring arm 430. The bottom of the screw rod 410 is provided with a constraint blind hole 450 for the lining constraint rod 360 to slide.

[0054] A side of the stirring arm 430 close to the outer wall of the screw rod 410 is in an arc shape, and the width and diameter of the arc shape are smaller than those of the screw rod 410 .

[0055] The damping shaft is used to increase the static friction coefficient between the stirring arm 430 and the notch 420, thereby improving the stability of the stirring arm 430 after it is deployed at a certain angle. As the screw 410 rotates, the sewage is mixed with the coagulant and the coagulant aid, thereby achieving dirt sedimentation.

[0056] At the same time, the magnet 440 can magnetically attract the stirring arm 430 that rotates into the gap 420 , allowing the driven sleeve 210 to pass through the gap 420 .

[0057] Please refer to Figure 1 The outer wall of the cylinder 100 is connected to a water inlet pipe near the top for inputting sewage; the outer wall of the cylinder 100 is connected to a water outlet pipe near the bottom; the water inlet pipe and the water outlet pipe are provided to discharge the treated water.

[0058] During use, the sewage to be treated is input into the cylinder 100, and the coagulant and coagulant aid are added from the top of the cylinder 100. Then, the drive motor 140 is started. The output end of the drive motor 140 drives the screw 410 and the stirring arm 430 to rotate, so that the sewage, coagulant and coagulant aid are fully mixed until the reaction produces flocculated sediment.

[0059] When the screw rod 410 rotates and stirs the sewage, coagulant and coagulant aid, the blocking component 200 will descend along the outer wall of the screw rod 410 into the cylinder 100 due to the action of the restraining strips 260. Since the first sector-shaped filter screen 230 will block the flocculent sediment floating in the sewage and on the surface of the sewage, as the first sector-shaped filter screen 230 approaches the dewatering component 300, when the blocking component 200 and the dewatering component 300 are fitted, the arc groove clamp 250 at the bottom of the rotating shaft 240 will extend into the give way groove 332 and squeeze the arc-shaped elastic member 370 toward both sides to deform in the inward and outward directions, allowing the arc groove clamp 250 to descend completely. The multi-stage electric push rod 110 is then controlled to work, and the telescopic end of the multi-stage electric push rod 110 will push up the cross beam 120, driving the screw rod 410 to rise synchronously, and the connected dewatering assembly 300 and the plugging assembly 200 will rise synchronously. Due to the resistance of the water body and the gravity of the dewatering assembly 300 and the plugging assembly 200, the lining restraint rod 360 will not rise when the screw rod 410 rises. When the screw rod 410 rises, the driven sleeve 210 drives the multiple groups of first support arms 2 20 rotates downward, at this time the first support arm 220 rotates downward around the connection point with the driven sleeve 210, and at the same time the second support arm 310 rotates upward around the connection point with the positioning plate 350, and the fan-shaped frames 330 at the tops of the two adjacent groups of second support arms 310 gradually approach each other, that is, the lining fan plate 340 enters the fan-shaped frames 330 on both sides. Due to the constraint of the arc-shaped elastic member 370, the lining fan plate 340 enters the receiving groove 333 according to the preset track, so that the cross section of the cylindrical dewatering component 300 is reduced, and the inner bottom of the dewatering component 300 and the blocking component 200 are both conical. At this time, the first fan-shaped filter screen 230 and the second fan-shaped filter screen 330 are The filter screen 320 changes from a right angle to an obtuse angle, and at the same time, it approaches the middle and becomes wavy, providing space for the first support arm 220 and the second support arm 310 to rotate close to the screw 410. The flocculated sediment inside the dewatering assembly 300 is concentrated at the pointed cone inside the dewatering assembly 300. When the screw 410 rises to the upper limit, it drives the dewatering assembly 300, which has been deformed and shrunk, to rise through the lining constraint rod 360, thereby driving the dewatering assembly 300 to rise until it is separated from the water inside the cylinder 100. At this time, the angles between the multiple sets of second support arms 310 and the screw 410 are acute, and the sediment is squeezed to drain the water inside.

[0060] When the dewatering assembly 300 and the plugging assembly 200 are shrunk, the restraining strip 260 is separated from the restraining groove 170, and the ball head rod 351 rises with the positioning plate 350 as pulled by the screw rod 410. The ball head rod 351 will slide along the inner wall of the spiral guide groove 160, so that the shrunk dewatering assembly 300 rotates at the bottom of the plugging assembly 200 with the axis of the screw rod 410 as the center of the circle. Under the obstruction of the water body inside the cylinder 100, the sediment can be driven to concentrate in the lowest depression in the dewatering assembly 300 (the inner conical surface of the dewatering assembly 300 after the reduction) so as to squeeze out the water inside the sediment. When the dewatering assembly 300 is separated from the water body in the cylinder 100, the shrunk dewatering assembly 300 will be driven to generate a certain centrifugal force, which can accelerate the dehydration of the sediment inside the dewatering assembly 300 and improve the efficiency of the dewatering assembly 300. The drainage effect is good, which makes it easy to remove the sediment, thereby improving the sewage treatment efficiency.
