Description

Technical Field

[0001] The present application relates to the technical field of sedimentation equipment, and in particular to a high-efficiency coagulation sedimentation equipment. Background Art

[0002] The working principle of coagulation and sedimentation equipment is mainly to add coagulants to wastewater. After the coagulants are hydrolyzed in water, they form colloids, which can adsorb and neutralize fluoride ions and other suspended matter, colloidal substances, etc. in the wastewater. Through the adsorption, bridging, and netting of coagulants, these substances form larger particles or flocs, which then settle to the bottom under the action of gravity, thereby achieving wastewater purification.

[0003] In order to realize the coagulation and sedimentation process, the existing coagulation and sedimentation equipment usually includes a sedimentation tank, a stirring device and a filtering device. In the specific operation process, the wastewater and the coagulant are introduced into the sedimentation tank and fully mixed by the stirring device, so that the coagulant reacts with the pollutants in the wastewater to form flocs. Subsequently, the wastewater is left to stand in the sedimentation tank for a period of time, and the flocs settle to the bottom of the tank under the action of gravity, and finally the sediment is collected by the filtering device. Although this traditional method can effectively remove pollutants in wastewater, it has some shortcomings in practical applications.

[0004] However, when treating wastewater, existing coagulation and sedimentation equipment usually needs to complete the steps of stirring, sedimentation and filtration in sequence, which makes the entire treatment process time-consuming and seriously affects the efficiency of wastewater treatment. Especially in large-scale industrial production, too long treatment time will lead to increased costs and reduced production efficiency, and cannot meet the needs of quickly treating large amounts of wastewater. Therefore, how to shorten the wastewater treatment time and improve the treatment efficiency has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] In order to shorten the wastewater treatment time, the present application provides a high-efficiency coagulation and sedimentation equipment.

[0006] The present application provides a high-efficiency coagulation and sedimentation equipment, which adopts the following technical solution: A high-efficiency coagulation and sedimentation equipment, comprising A coagulation cylinder, wherein a coagulation cavity is formed in the coagulation cylinder, a water inlet pipe and a drug-dosing pipe are arranged at the top of the coagulation cylinder, and a drainage pipe is arranged at the bottom of the coagulation cylinder; A stirring roller, rotatably connected to the coagulation cylinder and located in the coagulation chamber, wherein the coagulation cylinder is provided with a driving member for driving the stirring roller to rotate; A plurality of stirring blades are evenly spaced along the circumferential direction on the outer peripheral side of the stirring roller, and a collecting chamber is formed inside the stirring roller; The outer circumferential side of the stirring roller is formed with a plurality of inlets at even intervals along the circumferential direction, the inlets corresponding to the stirring blades one by one, and the inlets are located between adjacent stirring blades; The stirring roller is hinged with a blocking plate for blocking the inlet, and the stirring roller and the blocking plate are respectively formed with a plurality of water-permeable holes at even intervals; A control component is arranged on the stirring roller, and when the stirring blade moves upward from a horizontal state to a vertical state, the control component controls the blocking plate to flip into the collecting chamber; An elastic driving member, arranged on the stirring roller, when the stirring blade moves downward from a vertical state, the elastic driving member drives the blocking plate to flip to block the inlet; The coagulation cylinder is provided with a discharge pipe extending into the collection chamber, and the stirring roller and the discharge pipe rotate relative to each other; A water pump is arranged outside the coagulation cylinder, and a water suction port of the water pump is connected to the discharge pipe.

[0007] By adopting the above technical solution and the design of the stirring roller, the three steps of stirring, sedimentation and filtration can be carried out simultaneously, which greatly shortens the wastewater treatment time. The stirring blades on the stirring roller can continuously stir the wastewater and coagulant during the rotation process, promote the coagulant to fully react with the pollutants in the wastewater to form flocs. The design of the sealing plate and the water-permeable holes prevents the flocs from being collected into the collection chamber during the stirring process, but the wastewater flows back into the coagulation chamber through the water-permeable holes, further promoting the formation of flocs. When the stirring blade moves upward, the sealing plate opens to allow the flocs to enter the collection chamber; when the stirring blade moves downward, the sealing plate closes to limit the loss of flocs. Finally, the treated flocs are discharged through the discharge pipe and the water pump, and the discharge pipe discharges the wastewater in the coagulation chamber.

When the stirring blade moves downward from the vertical state, the drive coil spring drives the blocking plate to flip to block the inlet, restricting the outflow of the coagulant, so that the coagulant in the coagulation chamber can better coagulate with impurities such as fluoride ions in the wastewater, thereby improving the wastewater treatment efficiency.

At the same time, the stirring blade can drive and turn up more wastewater.

[0014] Optionally, limiting plates are respectively arranged on opposite sides of the stirring blade, and the limiting plates and the stirring blade surround to form a water collecting tank.

[0015] By adopting the above technical solution, limiting plates are arranged on the opposite sides of the stirring blades, and the limiting plates and the stirring blades are surrounded to form a water collecting trough, so that during the stirring process, the water collecting trough can scoop up more wastewater, thereby increasing the amount of wastewater entering the collection chamber.

[0016] Optionally, the stirring roller is provided with a rotating shaft rotating on the coagulation drum at two opposite ends thereof, the stirring roller is rotatably connected with a stirring shaft located in the collecting chamber, the stirring shaft extends into the rotating shaft, and a plurality of stirring blades are evenly spaced along the circumferential direction on the outer peripheral side of the stirring shaft; The rotating shaft is formed with a rotating groove surrounding the rotating shaft, and a connecting rack is arranged on the peripheral groove wall of the rotating groove; The coagulation cylinder is provided with a connecting shaft extending into the rotating groove, the outer peripheral side of the connecting shaft is rotatably connected with a transmission gear, and the connecting rack is meshed with the transmission gear; A power gear is disposed on the outer peripheral side of the stirring shaft, the power gear is meshed with the transmission gear, and the transmission gear is located between the power gear and the connecting rack.

[0029] The following is combined with Figure 1-8 This application is described in further detail.

[0030] The embodiment of the present application discloses a high-efficiency coagulation and sedimentation equipment.

The bottom of the coagulation cylinder 1 is fixedly connected to a drain pipe 14, which is connected to the coagulation chamber 11 for discharging wastewater in the coagulation chamber 11.

[0033] See also Figure 3 and Figure 4 The stirring roller 2 is a cylindrical structure, and is located in the coagulation chamber 11. The central axis of the stirring roller 2 coincides with the central axis of the coagulation drum 1. The two opposite ends of the stirring roller 2 are respectively fixedly connected with a rotating shaft 27, and the rotating shaft 27 is rotatably connected to the coagulation drum 1, and the central axis of the rotating shaft 27 coincides with the central axis of the coagulation drum 1.

[0034] The coagulation drum 1 is provided with a driving member 15 for driving the stirring roller 2 to rotate. The driving member 15 is a driving motor, which is fixed to the outer wall of the coagulation drum 1 through a bracket provided therewith, and the output shaft of the driving motor is rotationally connected to the coagulation drum 1, and the output shaft of the driving motor is fixedly connected to one of the rotating shafts 27 and is coaxially arranged. When the driving motor is started, the stirring roller 2 is driven to rotate through the rotating shaft 27.

[0035] A stirring blade 21 is fixedly connected to the outer peripheral side of the stirring roller 2. The stirring blades 21 are arranged in multiple groups at even intervals along the circumferential direction. In the embodiment of the present application, there are four groups of stirring blades 21. Each group of stirring blades 21 has multiple stirring blades 21 and is evenly spaced along the axial direction of the stirring roller 2. When the stirring roller 2 rotates, the stirring blades 21 stir and mix the wastewater and the coagulant in the coagulation chamber 11.

[0036] See also Figure 5 and Figure 6 A collecting chamber 22 is formed in the stirring roller 2, and an inlet 23 is formed on the outer peripheral side of the stirring roller 2, and the inlet 23 is connected to the collecting chamber 22. There are multiple inlets 23 and they are evenly spaced along the circumference. The inlet 23 corresponds to the stirring blades 21 one by one, and each inlet 23 is located between two adjacent stirring blades 21. The stirring roller 2 is rotatably connected with a hinge shaft 18, and the hinge shaft 18 passes through the inlet 23 and corresponds one by one. A sealing plate 24 is fixedly connected to the outer peripheral side of the hinge shaft 18. The sealing plate 24 is an arc-shaped plate structure. When the sealing plate 24 is flipped until the central axis coincides with the central axis of the coagulation cylinder 1, the sealing plate 24 blocks the inlet 23.

[0037] The coagulation and sedimentation device further includes an elastic component, and an elastic driving member is arranged on the stirring roller 2. The elastic driving member is a driving coil spring 26, which is sleeved on the outer peripheral side of the hinge shaft 18, one end of the driving coil spring 26 is clamped on the outer peripheral side of the hinge shaft 18, and the other end is clamped on the stirring roller 2. When the driving coil spring 26 is elastically released, the blocking plate 24 is driven to flip to block the inlet 23.

[0038] See also Figure 6 and Figure 7 The coagulation sedimentation device further includes a control component 3, which is arranged on the stirring roller 2. When the stirring blade 21 moves upward from a horizontal state to a vertical state, the control component 3 controls the blocking plate 24 to flip into the collecting chamber 22. The roller wall of the stirring roller 2 and the blocking plate 24 are respectively formed with water-permeable holes 25. There are multiple water-permeable holes 25 and they are evenly spaced. The water-permeable holes 25 are connected to the collecting chamber 22. When the blocking plate 24 flips to open the inlet 23, the wastewater in the collecting chamber 22 enters the collecting chamber 22. At this time, when the stirring roller 2 rotates, the wastewater flows out from the water-permeable holes 25 into the coagulation chamber 11 under the action of centrifugal force, and the flocculants in the wastewater are filtered and remain in the coagulation chamber 11.

[0039] The control assembly 3 includes a control column 31, a control gear 32 and a control rack 33. The control column 31 is slidably connected to the stirring blade 21 and the stirring roller 2, respectively, and the control column 31 corresponds to the hinge shaft 18 one by one. The control rack 33 is fixedly connected to the outer wall of the control column 31, and the control rack 33 slides in the stirring roller 2. The control gear 32 is fixedly connected to the outer peripheral side of the hinge shaft 18, the control gear 32 rotates in the stirring roller 2, and the control rack 33 is meshed with the control gear 32. A slide groove 111 is formed on the circumferential wall of the coagulation chamber 11. When the sealing plate 24 blocks the entrance 23, the control column 31 is inserted into the slide groove 111. When the control column 31 slides in the slide groove 111, the sealing plate 24 keeps the entrance 23 blocked. The stirring roller 2 is formed with a guide surface 112 . When the end of the control column 31 slides on the guide surface 112 , the control column 31 is guided to slide from the slide groove 111 to the wall of the coagulation chamber 11 . When one of the stirring blades 21 flips upward to a horizontal state, the control column 31 slides on the guide surface 112 and slides from the slide groove 111 to the wall of the coagulation chamber 11; and in the process of the control column 31 sliding on the guide surface 112, the control column 31 slides into the stirring roller 2, so that the control rack 33 drives the control gear 32 to rotate, and the hinge shaft 18 drives the blocking plate 24 to flip into the collecting chamber 22, and at this time the driving coil spring 26 enters a compressed state; and in the process of the control column 31 sliding on the wall of the coagulation chamber 11, the blocking plate 24 keeps the inlet 23 open; until the stirring blade 21 flips upward from a horizontal state to a vertical state, the control column 31 slides from the wall of the coagulation chamber 11 to align with the slide groove 111, and at this time the driving coil spring 26 is elastically released, pushing the blocking plate 24 to block the inlet 23, and at the same time, when the blocking plate 24 flips, the hinge shaft 18 drives the control column 31 to insert into the slide groove 111 through the control gear 32.

[0040] See also Figure 2 In the process of the stirring blade 21 flipping upward from the horizontal state to the vertical state, the wastewater brought up by the stirring blade 21 flows into the collection chamber 22 after passing through the inlet 23 along the stirring blade 21. In order to increase the amount of wastewater entering the collection chamber 22, the end of the stirring blade 21 away from the stirring roller 2 is slidably connected to the side wall of the coagulation chamber 11, and the side walls on both sides of the stirring blade 21 are fixedly connected with limiting plates 211 respectively, and a water collecting trough 212 is formed between the limiting plate 211 and the stirring blade 21. In the process of the stirring blade 21 flipping upward from the horizontal state to the vertical state, the water collecting trough 212 scoops up the wastewater, increasing the amount of wastewater flowing into the inlet 23 along the stirring blade 21.

[0041] See also Figure 4 The stirring roller 2 is provided with a stirring shaft 4, which is located in the collecting chamber 22, the central axis of the stirring shaft 4 coincides with the central axis of the stirring roller, and one end of the stirring shaft 4 is rotatably connected to the wall of the collecting chamber 22, and the other end of the stirring shaft 4 extends into the rotating shaft 27.

[0042] The rotating shaft 27 is formed with a rotating groove 271, which surrounds the stirring shaft 4, and a connecting rack 272 of an annular structure is fixedly connected to the groove wall of the rotating groove 271. The coagulation drum 1 is fixedly connected with a connecting shaft 273, which extends into the rotating groove 271, and a transmission gear 274 is rotatably connected to the outer peripheral side of the connecting shaft 273. The transmission gear 274 is rotatably connected to the rotating groove 271, and the connecting rack 272 is meshed with the transmission gear 274. The outer peripheral side of the stirring shaft 4 is fixedly connected with a power gear 42, which is rotatably connected to the rotating groove 271, and the power gear 42 is meshed with the transmission gear 274, and the transmission gear 274 is located between the power gear 42 and the connecting rack 272.

[0043] The outer circumference of the stirring shaft 4 is fixedly connected with stirring blades 41, and there are multiple stirring blades 41 and they are evenly spaced along the circumferential direction. When the stirring roller 2 rotates, the connecting rack 272 drives the power gear 42 to rotate through the transmission gear 274, so that the stirring shaft 4 enters a rotating state, and the rotation direction of the stirring shaft 4 is opposite to the rotation direction of the stirring roller 2. At this time, the stirring blades 41 stir the wastewater in the collection chamber 22, and increase the amount and speed of the wastewater flowing out of the collection chamber 22 through the water permeable holes 25.

[0044] A drainage groove 43 is formed in the stirring shaft 4, and the drainage groove 43 extends along the central axis direction of the stirring shaft 4. A water inlet hole 44 connected to the drainage groove 43 is formed on the side of the stirring blade 41 away from the stirring shaft 4. There are multiple water inlet holes 44 and they are evenly spaced along the axial direction of the stirring shaft 4. The drainage pipe 16 extends into the drainage groove 43, and the drainage pipe 16 rotates relative to the stirring shaft 4. A blocking pipe 161 is provided on the drainage pipe 16, and the outer peripheral side wall of the blocking pipe 161 is in sliding contact with the peripheral side wall of the drainage groove 43.

[0045] See also Figure 3 and Figure 4 , the coagulation drum 1 is fixedly connected with a discharge pipe 16, the discharge pipe 16 extends into the collection chamber 22, and the stirring roller 2 and the discharge pipe 16 rotate relative to each other. A water pump 17 is fixedly connected to the outer wall of the coagulation drum 1, the water suction side of the water pump 17 is fixed and connected with the discharge pipe 16, and the water discharge side of the water pump 17 is fixed and connected with a transmission pipe. When in use, the water pump 17 extracts the coagulant in the collection chamber 22, and transmits the coagulant to the next treatment process through the transmission pipe. The water pump 17 can be selected as a high-pressure pump or a centrifugal pump to ensure that the coagulant after coagulation can be effectively extracted.

[0046] See also Figure 7 and Figure 8The stirring shaft 4 is formed with a receiving groove 45, and the receiving groove 45 surrounds the discharge pipe 16. The stirring shaft 4 is fixedly connected with a power tooth 46, and the power tooth 46 is located on the side wall of the receiving groove 45. There are multiple power teeth 46 and they are evenly spaced along the circumferential direction. In the embodiment of the present application, there are four power teeth 46 and they correspond to the stirring blades 41 one by one.

[0047] See also Figure 6 and Figure 8 A push groove 163 of a "T"-shaped structure is formed on the outer peripheral side wall of the drain pipe 16 along the circumferential direction. The drain pipe 16 is provided with a push block 164 of a "T"-shaped structure, and the push block 164 is slidably connected in the push groove 163. The drain pipe 16 is provided with a push spring 165, which is installed in the push groove 163. One end of the push spring 165 abuts against the push block 164, and the other end abuts against the groove wall of the push groove 163. When the push spring 165 is elastically released, the push block 164 is pushed to slide in the push groove 163 until the push block 164 abuts against the groove wall on one side of the end of the push groove 163. The outer peripheral side of the drain pipe 16 is fixedly connected with a limiting tooth 166, which is adjacent to the push groove 163, and when the push spring 165 pushes the push block 164 to abut against the groove wall on the end of the push groove 163, the push block 164 is adjacent to the limiting tooth 166. When one of the power teeth 46 is located between the pushing block 164 and the limiting tooth 166 , the stirring blade 41 corresponding to the power tooth 46 is in a vertically downward state, which is beneficial for extracting the coagulant in the collecting chamber 22 .

[0048] The wall of the push groove 163 is fixedly connected with a friction layer 167, and the friction layer 167 is far away from the limiting tooth 166. When the push block 164 slides on the friction layer 167, the friction layer 167 slows down the speed of the push block 164 sliding toward the limiting tooth 166. When the stirring shaft 4 rotates, the power tooth 46 pushes the push block 164 to slide in the direction away from the limiting tooth 166. At this time, the push block 164 squeezes the push spring 165 until the push block 164 approaches the wall of the push groove 163 away from the limiting groove. The push block 164 slides on the friction layer 167, and the stirring shaft 4 continues to rotate. The push block 164 can slide past the power tooth 46, and the next adjacent power tooth 46 slides on the limiting tooth 166, so that the next adjacent power tooth 46 can slide between the limiting tooth 166 and the push block 164. When the stirring shaft 4 stops rotating and the push spring 165 is elastically released, the push block 164 pushes the push block 164 to move toward the direction of the limiting tooth 166. At this time, the push block 164 pushes the power tooth 46 between the push block 164 and the limiting tooth 166 to slide to abut against the power tooth 46, thereby correcting the stirring blade 21 so that the corresponding stirring blade 41 can be in a vertical downward state.

[0049] A plugging tube 161 is fixedly connected to the outer peripheral side wall of the discharge pipe 16, and the outer peripheral side wall of the plugging tube 161 is in sliding contact with the peripheral side wall of the discharge groove 43, and a water inlet 162 is formed on the bottom wall of the plugging tube 161. When one of the stirring blades 21 is in a vertical downward state, the water inlet 162 is directly opposite to the water inlet hole 44 on the stirring blade 21 in the vertical downward state, and the water inlet holes 44 of the remaining stirring blades 21 are closed by the wall of the plugging tube 161, which is conducive to improving the effect of extracting the coagulant in the collection chamber 22.

[0050] The implementation principle of a high-efficiency coagulation and sedimentation device in the embodiment of the present application is: Through the design of the stirring roller 2, the three steps of stirring, sedimentation and filtration are carried out simultaneously, which greatly shortens the wastewater treatment time. The stirring blade 21 on the stirring roller 2 can continuously stir the wastewater and coagulant during the rotation process, promote the coagulant to fully react with the pollutants in the wastewater to form flocs. The design of the blocking plate 24 and the water-permeable hole 25 prevents the flocs from being collected into the collection chamber 22 during the stirring process, but the wastewater flows back into the coagulation chamber 11 through the water-permeable hole 25, further promoting the formation of flocs. When the stirring blade 21 moves upward, the blocking plate 24 opens to allow the flocs to enter the collection chamber 22; when the stirring blade 21 moves downward, the blocking plate 24 closes to prevent the flocs from being lost. Finally, the treated flocs are discharged through the discharge pipe 16 and the water pump 17, and the discharge pipe 16 discharges the wastewater in the coagulation chamber 11.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
