Description

Technical Field

[0001] The invention relates to the technical field of flocculation water treatment, in particular to a space-intensive flocculation water treatment device. Background Art

[0002] The space-intensive flocculation water treatment device is a new type of water treatment technology. It mainly improves the problems of traditional flocculation sedimentation devices, such as large footprint and slow treatment speed. The flocculation water treatment device adds coagulants, flocculants, coagulants and other flocculation agents to the sewage to make the fine pollution particles in the sewage aggregate into larger flocs, which settle because their density is greater than that of water, thereby achieving water purification.

[0003] For example, a space-intensive flocculation water treatment device with publication number CN116621298A comprises a sedimentation separation mechanism and a spiral coil wound on the outside thereof, wherein a sewage inlet is arranged at one end of the spiral coil and the other end is passed through the first inner cone, and the flocculation process occurs in the coiled spiral coil, pollutants and flocculants flow in the spiral pipe, and are mixed, collided and flocculated under the action of centrifugal force, and per unit volume, the upper and lower double cone shell structure can wind more spiral coils on the outside of the cone shell compared to the cylindrical shell structure, and a first inner cone and a second inner cone located below the first inner cone are arranged in the sedimentation separation mechanism, and multiple layers of sedimentation cone plates are arranged between the first inner cone and the first outer cone.

[0004] The above-mentioned flocculation water treatment device is used to better mix the flocculant and sewage through the spiral coil. Part of the flocculant is put in from the spiral coil. The flocculant and the sewage have the same path and flow speed. Therefore, the flocculant at the rear cannot catch up with the sewage in the front, and the mixing effect is poor. At the same time, the setting of the cone and the sedimentation cone plate separates the water from the flocculants. The flocculants are adsorbed under the sedimentation cone plate, and some flocculants that are not firmly adsorbed will fall downward due to their own gravity, which will cause part of the flocculants to mix with the water, resulting in a poor separation effect. Summary of the invention

[0009] Preferably, a mounting tube is provided in the inner cylinder, a chain assembly is provided inside the inner cylinder, and a chain of the chain assembly is rotatably connected to the fixed plate;

[0010] The liquid output by the mixing mechanism is input into the cavity of the inner cylinder through the installation pipe, impacts the fixed plate and the connecting plate, and pushes the fixed plate and the connecting plate to move along the chain.

[0011] Preferably, a magnet is installed at the end of the inner cylinder away from the ground, and the fixed plate is made of iron. When the fixed plate moves to the highest point of the chain assembly, it rotates under the influence of the magnetic force of the magnet, so that the same set of fixed plates and connecting plates carry the flocculants in the inner cylinder to flip into the limiting plate.

[0012] Preferably, the position of the mounting tube is higher than that of the filter plate, a limiting groove is provided inside the inner cylinder, the curvature of the limiting groove is the same as that of the limiting plate, a protrusion is engaged inside the limiting groove, and the other end of the protrusion is installed inside the fixed plate and the connecting plate through a return spring, and the same group of fixed plates and connecting plates are kept level through the limiting groove.

[0013] Preferably, a controller and a water pump are installed on the water inlet pipe, and the controller is electrically connected to the water pump, so that the water output of the water pump is a sinusoidal curve through the controller.

[0014] Preferably, the mixing mechanism includes a water channel, a guide plate and a supporting spring. The water channel is installed between the outer cylinder and the inner cylinder. The water channel is fitted with the outer side of the inner cylinder. The inside of the water channel is rotatably connected with the guide plate. A supporting spring is arranged between the guide plate and the water channel. During the flow of sewage in the water channel, the guide plate blocks the flow of water to promote the mixing of flocculant and sewage.

[0015] Preferably, the water channel is a spiral opening structure, the central angle corresponding to the arc of the water channel cross section is greater than 180 degrees, a through groove begins to be formed inside the inner cylinder, a connecting rod is slidably engaged inside the through groove, and the connecting rod moves up and down around the water channel.

[0016] Preferably, a scraper rod is slidably arranged inside the water channel, a connecting rod is connected to the scraper rod, the scraper rod is located below the guide plate, and the connecting rod is located in the middle of the staggered guide plates.

[0017] Preferably, a servo motor is installed on the outer cylinder, a small gear is installed on the output end of the servo motor, the small gear is meshed with a large gear, and the large gear penetrates and is fixed on the inner cylinder.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The flocculant and sewage are better mixed by setting the mixing mechanism. The flocculant added later can catch up with the sewage that has flowed in front. The sewage with fluctuating flow rate flows through. Through the cooperation of the guide plate and the reset spring, the guide plate exerts different forces on the sewage with different flow rates. At the same time, the guide plate limits the sewage and flocculant, so that the sewage and flocculant are reflected in the water body, so that the added flocculant can be mixed with the sewage before and after. In addition, the flow speed of the sewage and flocculant changes. At the same time, the sewage and flocculant generate centrifugal force during the flow of the sewage and flocculant inside the water channel, which promotes the sewage and flocculant to condense into larger alum flowers during the flow process, which is easy to form large and dense flocs, which can increase the floc sedimentation speed, which is conducive to the improvement of the subsequent sedimentation separation efficiency, and at the same time saves the space and stirring device of the general flocculation unit.

[0020] 2. Through the arrangement of the through groove, scraper rod and connecting rod, the inner cylinder rotates to rotate the through groove, and the through groove pulls the connecting rod during the rotation process, and the connecting rod pulls the scraper rod to slide inside the water channel. When the scraper rod slides from bottom to top, the movement direction of the scraper rod is opposite to the flow direction of water. The scraper rod exerts force on the water, which will change the internal water flow speed and promote the mixing of water and flocculant. When the scraper rod slides from top to bottom, the promotion effect of the scraper rod and water is reduced. During the sliding process of the scraper rod, the sludge adsorbed inside the water channel is scraped to prevent the adsorbed sludge from adsorbing the flocculant and prevent the flow of flocculant and sewage from being affected.

[0021] 3. The flocculants are separated from the water by setting the fixed plate, the filter plate and the connecting plate. The gravity of the flocculants and the water will push the same set of fixed plates and connecting plates. The fixed plates and connecting plates rotate counterclockwise. When the fixed plates and connecting plates move to the filter plate position, the water flows to the middle position inside the limit plate, and the flocculants stay on the fixed plates and connecting plates. After the fixed plates and connecting plates rotate to the top, the magnets and the connecting plates are adsorbed on each other, and the connecting plates and the fixed plates are rotated by the suction between the magnets and the connecting plates, so that the flocculants on the connecting plates and the fixed plates face downward, and the connecting plates and the fixed plates are rotated instantly by suction. The instantaneous force can promote the flocculants to fall. It has more functions in a certain space, so that the water treatment device has a space-intensive effect.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 8 , the present invention provides a technical solution:

[0033] A space-intensive flocculation water treatment device comprises an outer cylinder 1 and an inner cylinder 5, wherein the inner cylinder 5 rotates inside the outer cylinder 1, a separation mechanism is arranged on the inner cylinder 5, a fixing plate 13, a filter plate 22 and a limit plate 14 of the separation mechanism are arranged, the limit plate 14 is arranged inside the inner cylinder 5, a fixing plate 13 and a connecting plate 23 are equidistantly fitted inside the inner cylinder 5, the connecting plate 23 is fixed to the fixing plate 13, and the sides of the connecting plate 23 and the fixing plate 13 are fitted to the inner cylinder 5 and the limit plate 14 respectively, the filter plate 22 is arranged below the limit plate 14, the position of the mounting tube 4 is higher than the position of the filter plate 22, a mounting tube 4 is provided on the inner cylinder 5, the fixing plate 13 is made of iron, a magnet 24 is arranged on the inner cylinder 5, a chain assembly 19 is arranged inside the inner cylinder 5, a chain of the chain assembly 19 is rotatably connected to the fixing plate 13, a reset assembly is arranged at the rotating position of the fixing plate 13 and the chain assembly 19, a closed cavity is formed below the limit plate 14, and the connecting tube 15 is connected.

[0034] After being fully mixed, the water enters the inner cylinder 5 through the installation pipe 4, and the water flows to the fixed plate 13 and the connecting plate 23. The weight of the water pushes the fixed plate 13 and the connecting plate 23 downward, and the chain assembly 19 is set to make all the fixed plates 13 and the connecting plates 23 rotate counterclockwise. The water is limited by the setting of the limiting plate 14 and the inner cylinder 5. When the fixed plate 13 and the connecting plate 23 rotate to the filter plate 22, due to the fluidity of the water, the water flows through the filter plate 22 to the inside of the limiting plate 14, and the flocculants stay on the fixed plate 13 and the connecting plate 23, so as to separate the flocculants from the water. Move upward and separate from the limit groove 16. When the fixed plate 13 and the connecting plate 23 rotate to vertical, magnetic force is generated between them and the magnet 24. The suction force of the magnet 24 causes the fixed plate 13 and the connecting plate 23 to rotate instantly, and the flocs on the fixed plate 13 and the connecting plate 23 fall off. The instantaneous rotation force promotes the flocs to fall off faster, so that the flocs are separated from the connecting plate 23 and the fixed plate 13, and the flocs are fully separated from the water. When the fixed plate 13 and the connecting plate 23 continue to move out of the magnetic force range of the magnet 24, the reset assembly causes the fixed plate 13 and the connecting plate 23 to rotate in the opposite direction and return to the position before rotation, so that the fixed plate 13 fits with the limit plate 14.

[0035] The inner cylinder 5 is set as a "U"-shaped structure, and a limiting groove 16 is opened inside the inner cylinder 5. The curvature of the limiting groove 16 is the same as the curvature of the limiting plate 14. A protrusion 18 is engaged inside the limiting groove 16. The other end of the protrusion 18 and the interior of the fixed plate 13 and the connecting plate 23 are provided with a return spring 17. The setting of the limiting groove 16 keeps the fixed plate 13 and the connecting plate 23 level, and the end position of the limiting groove 16 is inclined.

[0036] When the fixed plate 13 and the connecting plate 23 slide in the vertical direction and downward, the protrusion 18 keeps sliding in the limiting groove 16. The limiting groove 16 is set to keep the fixed plate 13 and the connecting plate 23 horizontal during the movement, so as to prevent the gravity of the sewage from causing the fixed plate 13 and the connecting plate 23 to flip over. When the fixed plate 13 and the connecting plate 23 slide upward, the end position of the limiting groove 16 pushes the protrusion 18 to move the protrusion 18 to the inside of the fixed plate 13 and the connecting plate 23, so that the fixed plate 13 and the connecting plate 23 can slide smoothly and flip over when sliding upward.

[0037] A water inlet pipe 25 is installed on the outer cylinder 1, and a connecting pipe 15 is installed on the inner cylinder 5. Sewage enters through the water inlet pipe 25 and comes out from the connecting pipe 15. A controller 2 and a water pump 3 are installed on the water inlet pipe 25. The controller 2 is electrically connected to the water pump 3. The controller 2 makes the water output of the water pump 3 a sine curve. The guide plates 20 on both sides are staggered with each other. A mixing mechanism is arranged on the outer cylinder 1. The separation mechanism separates the flocculant from the water to increase the purity of the water. The mixing mechanism makes the flocculant and the fine pollution particles in the water agglomerate and mix better. The mixing mechanism includes a water channel 9, a guide plate 20 and a support spring 21. The water channel 9 is installed inside the outer cylinder 1. The water channel 9 is fitted with the outer side of the inner cylinder 5. The guide plate 20 is rotatably connected inside the water channel 9. A support spring 21 is arranged between the guide plate 20 and the water channel 9. The guide plate 20 blocks the water and reflects the water to various places, thereby making the flocculant and the sewage mix better, thereby producing more and larger flocculants. The water channel 9 is arranged in a spiral structure.

[0038] The water pump 3 allows the sewage to enter the outer cylinder 1 through the water inlet pipe 25. The controller 2 controls the water pump 3 so that the flow rate of the sewage from the water pump 3 is a sine curve, thereby making the flow rate of the sewage constantly change, thereby making the force of the water on the guide plate 20 change. The force is changing, thereby making the guide plate 20 swing repeatedly. The magnitude and direction of the force on the water are changed by the swing, and the flow direction of the water is constantly changed, so as to avoid the force generated by the flow of water causing the guide plate 20 to remain stationary, and the sewage and flocculant flow downward in the water channel 9. Centrifugal force is generated in the process, and mixing, collision and flocculation occur under the action of centrifugal force. The pollutant particles and flocculants collide in the circular motion, and flocs are formed quickly. The flocs gradually move toward the periphery under the action of centrifugal force. During the movement, they condense into larger alum flowers, and it is easy to form large and dense flocs. Such flocs have a fast sedimentation speed, which is beneficial to the improvement of subsequent sedimentation and separation efficiency. At the same time, it saves the space and stirring device of the general flocculation unit, and can make the flocculant and sewage mix better to avoid insufficient contact and flocculation between the two.

[0039] The central angle corresponding to the arc of the cross section of the water channel 9 is greater than 180 degrees. The upper end of the water channel 9 is set as an opening. A through groove 10 begins to be provided inside the inner tube 5. A connecting rod 12 is slidably engaged inside the through groove 10. The connecting rod 12 is moved up and down around the water channel 9 through the setting of the through groove 10. A scraper rod 11 slides inside the water channel 9. The connecting rod 12 is installed on the scraper rod 11. The scraper rod 11 can pass under the guide plate 20. The connecting rod 12 can pass through the middle position of the left and right guide plates 20. A servo motor 7 is installed on the outer tube 1. A small gear 6 is installed on the output end of the servo motor 7. The small gear 6 is meshed with the large gear 8, and the large gear 8 is fixed on the inner tube 5.

[0040] The servo motor 7 causes the small gear 6 to rotate forward and reversely. The large gear 8 rotates during the rotation of the small gear 6. The rotation of the large gear 8 drives the inner cylinder 5 to rotate synchronously. The rotation of the inner cylinder 5 drives the through groove 10 to rotate synchronously. The rotation of the through groove 10 pushes the connecting rod 12 to push the connecting rod 12 to slide inside the water channel 9. The connecting rod 12 slides during the sliding process and drives the scraper rod 11 to slide synchronously. The sliding of the scraper rod 11 processes the sludge on the inner wall of the water channel 9 to prevent the flocculant from being adsorbed on the sludge, and also prevents the sludge from affecting the normal flow of the flocculant and sewage. When the scraper rod 11 slides downward and upward, the sliding direction of the scraper rod 11 is opposite to the flow direction of the water. The scraper rod 11 will push part of the water, change the flow speed of the water, and further promote the mixing of the flocculant and sewage.

[0041] The above structure achieves multiple effects and produces more functions within a certain space, so that the water treatment device has space-intensive functions.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
