Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to automatic controlled dosage dosing equipment for sewage treatment. Background Art

[0002] With the acceleration of urbanization and the improvement of industrialization, the discharge of domestic sewage has gradually increased. Therefore, sewage treatment has become an important environmental protection task. In the sewage treatment process, it is usually necessary to add chemicals to the sewage to remove pollutants, kill bacteria and improve water quality.

[0003] Most of the existing sewage treatment dosing devices use gravity to discharge materials and control the opening of the discharge port through a valve. In this way, the amount of material discharged each time will be unstable, resulting in inaccurate adjustment of the agent concentration. The agent is easy to block the valve under the action of gravity, and the agent cannot be evenly added during the agent addition process, resulting in uneven mixing of the agent and sewage. Summary of the invention

[0004] In order to solve the above problems, the present invention provides an automatic controlled dosage dosing device for sewage treatment.

[0005] The technical solution of the present invention is: an automatic controlled dosage dosing equipment for sewage treatment, comprising a mixing tank, a stirring shaft vertically arranged in the mixing tank, a rotating disk horizontally rotatably arranged in the mixing tank, and a feeding tank fixedly arranged on the upper part of the mixing tank; the lower end of the stirring shaft passes through the rotating disk and is fixedly connected to the rotating disk; the feeding tank is divided into an arc-shaped separation bin and an arc-shaped silo by a partition, and a torsion spring shaft is vertically rotatably arranged in the arc-shaped separation bin; an arc-shaped material pipe for connecting the arc-shaped separation bin and the arc-shaped silo is arranged in the feeding tank, and the arc-shaped material pipe sequentially comprises a vibrating part and a feeding part located in the arc-shaped separation bin and a feeding part located in the arc-shaped separation bin. The feeding part of the arc-shaped silo, the discharge part is slidably provided with a pressure ring, one side of the pressure ring is connected to one side of the partition through a spring, an opening is provided on the arc-shaped material tube on the other side of the pressure ring, and the opening is provided with a gate that is triggered by the pressure ring to control the opening or closing, and a discharge port is provided on the bottom surface of the arc-shaped partition bin located on the other side of the partition; a torsion plate is sleeved on the torsion spring shaft, and the torsion plate has a sliding hole that is slidably connected to the arc-shaped partition bin, the lower end of the torsion spring shaft passes through the discharge tank and is sleeved with a lever, and the rotating disk is provided with a hopper that is rotatably docked with the discharge port, and a push block that cooperates with the lever to rotate and push the torsion spring shaft to twist.

[0006] Description: The above equipment drives the rotating disk to rotate through the stirring shaft. When the rotating disk rotates, it will drive the hopper and the push block to rotate. When the hopper rotates to the bottom of the discharge port, the push block will push the lever to rotate, so that the torsion spring shaft drives the torsion plate to rotate, and the torsion plate will separate from the pressure ring. At this time, the opening is closed, and the torsion plate continues to rotate and vibrates in coordination with the vibration part to fill the arc-shaped material tube with medicine. After the push block is separated from the lever, the torsion spring shaft will drive the torsion plate to reset, so that the torsion plate squeezes the pressure ring to open the opening and release the medicine into the arc-shaped separation bin. With the next rotation of the torsion plate, the torsion plate will push the medicine into the discharge port and fall into the hopper. Compared with the method of relying on gravity for discharge, the single discharge amount of the arc-shaped material tube is more stable, and the medicine will not be accumulated at the discharge port due to gravity, causing the discharge port to be blocked.

[0007] Furthermore, the vibration part is provided with a plurality of protrusions, and the sliding hole is provided with an extrusion column which cooperates with the protrusions to make the material tube vibrate.

[0008] Description: When the torsion plate rotates, the extrusion column can intermittently contact the convex block, so that the arc-shaped material tube can vibrate intermittently, so that the medicine can be fully filled into the arc-shaped material tube under the action of vibration.

[0009] Furthermore, the gate is a baffle plate slidably arranged on one side of the opening and used to control the opening or closing of the opening, the baffle plate is slidably connected to the arc groove on the inner wall of the arc-shaped material tube, and the baffle plate is fixedly connected to the inner wall of the pressure ring.

[0010] Note: When the torsion plate rotates, it will separate from the pressure ring, causing the pressure ring to reset under the action of the spring, allowing the baffle to close the opening.

[0011] Furthermore, a valve plate is rotatably provided in the hopper for controlling the opening and closing of the rotating hopper, and one end of the rotating shaft of the valve plate is connected to the hopper through a torsion spring.

[0012] Note: When the weight of the reagent in the hopper is sufficient, the valve plate will rotate open under the action of gravity, releasing the reagent in the hopper into the sewage.

[0013] Furthermore, the lower end of the push block passes through the rotating disk and is slidably connected to the rotating disk, and a lifting plate is provided at the lower end of the push block. The other end of the rotating shaft of the valve plate passes through the hopper and is provided with a gear, and the lifting plate is provided with a rack meshing with the gear.

[0014] Note: When the weight of the agent in the hopper is sufficient, the valve plate will rotate, causing the gear to drive the rack to descend, and the lifting plate to drive the push block to descend. At this time, the push block cannot contact the lever, so that when the hopper is unloading, the rotating disk does not need to stop rotating, and the unloading tank can stop unloading, ensuring that the amount of agent in the hopper is more accurate, and the hopper can release the agent following the rotation of the rotating disk, so that the agent is evenly applied to the sewage.

[0015] Furthermore, a sleeve is sleeved on the stirring shaft located above the rotating disk, and the sleeve is fixedly connected to the top surface of the mixing tank. The rotating disk is provided with a material blocking bar, and the material blocking bar consists of a fixed bar with one end fixed on the second sleeve, and a movable bar rotatably arranged at the other end of the fixed bar. The lever is provided with a swing rod for driving the movable bar to swing by its swing, and the swing rod is hinged to the movable bar through a connecting rod.

[0016] Description: The blocking bar can stop the medicine falling from the rotating disk when the rotating disk rotates. When the push block contacts the lever, the lever can drive the swing lever to swing. The swing lever can pull the movable bar to swing through the connecting rod, so that the movable bar can push the medicine on the outside of the rotating disk to the middle of the blocking bar. When the hopper passes through, the medicine can fall directly into the hopper to reduce the waste of medicine.

[0017] Furthermore, a spiral plate is provided on the bottom surface of the discharge tank, and a knocking mechanism is provided on the bottom surface of the discharge tank for knocking the spiral plate by rotating the torsion plate.

[0018] Description: The spiral plate can prevent the medicine from accumulating on the bottom of the discharge tank, and the knocking mechanism can knock the spiral plate to ensure that the medicine can be fully filled to the bottom of the arc silo.

[0019] Furthermore, the knocking mechanism includes a movable frame vertically slidably arranged on the bottom surface of the discharge tank, and a sliding rod horizontally slidably arranged on the other side partition; the movable frame is connected to the bottom surface of the discharge tank through a spring, and a knocking column in contact with the spiral plate is provided at the upper end of the movable frame, the sliding rod is connected to the side wall of the arc-shaped partition bin through an airbag, and a plurality of convex columns are provided on the side wall of the sliding rod for pushing the movable frame up and down by sliding.

[0020] Note: When the torsion plate rotates, it will squeeze the slide bar. When the slide bar slides, the convex column will intermittently press down the movable frame. During the up and down movement of the movable frame, the knocking column will intermittently knock the spiral plate to make the spiral plate vibrate, so as to prevent the medicine from accumulating on the spiral plate and being unable to fall.

[0021] The beneficial effects of the present invention are:

[0022] (1) The present invention rotates the rotating disk to drive the torsion spring shaft to rotate intermittently, and the torsion plate will cooperate with the vibration part to fully fill the arc-shaped material tube with medicine. When the push block is separated from the lever, the torsion spring shaft will drive the torsion plate to reset, so that the torsion plate squeezes the pressure ring to open the opening and release the medicine into the arc-shaped separation chamber. With the next rotation of the torsion plate, the torsion plate will push the medicine into the discharge port and fall into the hopper. Compared with the method of relying on gravity for discharge, the single discharge amount of the arc-shaped material tube is more stable, and the medicine will not be completely accumulated at the discharge port due to gravity, causing the discharge port to be blocked.

[0023] (2) When the weight of the agent in the hopper of the present invention is sufficient, the valve plate will rotate, causing the gear to drive the rack to descend, and the lifting plate to drive the push block to descend. At this time, the push block cannot contact the lever, so that when the hopper is unloading, the rotating disk does not need to stop rotating, and the unloading tank can stop unloading, ensuring that the amount of agent in the hopper is more accurate, and the hopper can follow the rotation of the rotating disk to release the agent, so that the agent is evenly applied to the sewage.

[0024] (3) In the present invention, when the torsion plate rotates, the slide rod will be squeezed, and when the slide rod slides, the convex column will intermittently press down the movable frame. During the up and down movement of the movable frame, the knocking column will intermittently knock the spiral plate, causing the spiral plate to vibrate, thereby preventing the medicine from accumulating on the spiral plate and being unable to fall.

[0042] like Figure 3 As shown, the material discharge tank 2 is divided into an arc-shaped partition bin 22 and an arc-shaped material bin 29 by a partition, and a torsion spring shaft 21 is provided in the arc-shaped partition bin 22 for vertical rotation; an arc-shaped material pipe 24 for connecting the arc-shaped partition bin 22 and the arc-shaped material bin 29 is provided in the material discharge tank 2, and the arc-shaped material pipe 24 is connected to the sliding column provided on the right partition by a slide groove provided thereon, and the length of the slide groove is 3 cm, and the arc-shaped material pipe 24 includes a vibration part and a material discharge part located in the arc-shaped partition bin 22 and a feeding part located in the arc-shaped material bin 29 from left to right;

[0043] like Figure 5As shown, a pressure ring 242 is slidably provided on the discharge part, and the right side of the pressure ring 242 is connected to the right partition through a spring, and an opening 241 is provided on the arc-shaped material tube 24 on the left side of the pressure ring 242, and a gate that is triggered by the pressure ring 242 to control the opening or closing of the opening 241 is provided on the opening 241, and a discharge port 221 is provided on the bottom surface of the arc-shaped partition bin 22 on the left partition; a torsion plate 23 is sleeved on the torsion spring shaft 21, and the torsion plate 23 has a sliding hole that is slidably connected to the arc-shaped partition bin 22, and the lower end of the torsion spring shaft 21 passes through the discharge tank 2 and A lever 25 is sleeved, the upper end of the torsion spring shaft 21 passes through the top surface of the arc-shaped partition bin 22 and is sleeved with a stirring blade 211, the torsion spring sleeve of the torsion spring shaft 21 is arranged between the stirring blade 211 and the arc-shaped partition bin 22, the rotating disk 12 is provided with a hopper 16 that is rotatably docked with the discharge port 221, and a push block 17 that is rotatably coordinated with the lever 25 to push the torsion spring shaft 21 to twist, the push block 17 and the hopper 16 are located in the same radial direction of the rotating disk 12, and during the contact between the push block 17 and the lever 25, the discharge port 221 can always be docked with the hopper 16;

[0044] like Figure 4 , Figure 8 As shown, the vibration part has five protrusions 243, and the sliding hole has an extrusion column 231 that cooperates with the protrusions 243 to make the material tube 24 vibrate;

[0045] like Figure 6 , Figure 7 As shown, the gate is a baffle 244 which is slidably arranged on the right side of the opening 241 and is used to control the opening or closing of the opening 241. The baffle 244 is slidably connected to the arc groove 245 provided on the inner wall of the arc-shaped material tube 24, and the arc length of the baffle 244 is 2 cm longer than the arc length of the opening 241 to ensure that the baffle 244 can completely close the opening 241. The length of the arc groove 245 is equal to that of the baffle 244 to ensure that the baffle 244 can be retracted into the arc groove 245 to open the opening 241. The baffle 244 is fixedly connected to the inner wall of the pressure ring 242;

[0046] like Fig. 9 , Fig.10 As shown, two valve plates 161 are rotatably provided in the hopper 16 for controlling the opening and closing of the hopper 16 by rotation. Both valve plates 161 are tilted toward the center of the hopper 16, and the left end of the rotating shaft of the valve plate 161 is connected to the hopper 16 through a torsion spring; the lower end of the push block 17 passes through the rotating disk 12 and is slidably connected to the rotating disk 12, and a lifting plate 18 is provided at the lower end of the push block 17, the right end of the rotating shaft of one valve plate 161 passes through the hopper 16 and is provided with a gear 162, and the lifting plate 18 is provided with a rack 181 meshing with the gear 162.

[0047] The working principle of the above-mentioned device is as follows: in the initial state, the torsion plate 23 contacts the pressure ring 242, the opening 241 is opened, and water can be introduced through the water inlet 14, and the motor 13 drives the stirring shaft 11 to rotate, the stirring shaft 11 drives the rotating disk 12 to rotate, and the rotating disk 12 drives the hopper 16 and the push block 17 to rotate, and the push block 17 will intermittently contact the lever 25 and push the torsion spring shaft 21 to rotate, and the torsion spring shaft 21 will drive the torsion plate 23 to rotate counterclockwise, so that the torsion plate 23 is separated from the pressure ring 242, and the pressure ring 242 will reset under the action of the spring and drive the baffle 244 to close the opening 241, and during the counterclockwise rotation of the torsion plate 23, the extrusion column 231 will contact the protrusion 243, so that the arc The material tube 24 vibrates, so that the medicine on the right side of the arc-shaped material tube 24 is gradually filled to the left side of the arc-shaped material tube 24 under the action of vibration. As the push block 17 separates from the lever 25, the torsion spring shaft 21 drives the torsion plate 23 to reset, so that the torsion plate 23 rotates clockwise and squeezes the pressure ring 242 to open the opening 241. At this time, the medicine falls into the bottom surface of the arc-shaped separation bin 22. As the pressure ring 242 slides to the rightmost end, the torsion plate 23 continues to squeeze the arc-shaped material tube 24, so that the arc-shaped material tube 24 slides to the right and inserts into the medicine, so that the medicine enters the right end of the arc-shaped material tube 24. As the push block 17 contacts the lever 25 next time, the torsion plate 23 pushes the medicine on the bottom surface of the arc-shaped separation bin 22 into the discharge port 221.

[0048] The medicine falls into the hopper 16 through the discharge port 221. When the weight of the medicine in the hopper 16 is sufficient, under the action of gravity, the valve plate 161 will rotate to open the hopper 16. At the same time, the rotating shaft of the valve plate 161 will drive the gear 162 to rotate, so that the gear 162 drives the rack 181 to move downward, and the rack 181 will drive the push block 17 to descend through the lifting plate 18. At this time, the push block 17 cannot contact the lever 25, and the rotating disk 12 will drive the hopper 16 to rotate and discharge the medicine, so that the medicine enters the water and is prepared under the action of the stirring shaft 11.

[0049] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that the valve plate 161 controls the opening and closing of the hopper 16 through a motor drive, and a weight sensor and a PLC controller are provided on the valve plate 161, and the weight sensor and the motor are electrically connected to the PLC controller, wherein the motor, the weight sensor and the PLC controller are all existing technology products, not shown in the figure.

[0050] The working principle of the hopper 16 is as follows: the weight sensor can transmit weight data to the PLC controller. When the weight of the medicine in the hopper 16 is sufficient, the PLC controller controls the motor to drive the valve plate 161 to rotate, so that the hopper 16 opens.

[0051] Example 3: Fig.11As shown, this embodiment is basically the same as Example 1, except that a sleeve 19 is sleeved on the stirring shaft 11 located above the rotating disk 12, and the sleeve 19 is fixedly connected to the top surface of the mixing tank 1, and a material blocking bar is provided on the rotating disk 12, and the material blocking bar is composed of a fixed bar 191 fixedly set on the second sleeve 19 at the left end, and a movable bar 192 rotatably set at the right end of the fixed bar 191, and the movable bar 192 is rotatably connected with a rotating shaft provided on the fixed bar 191, and a swing rod 251 is provided on the lever 25 for driving the movable bar 192 to swing by its swinging, and the swing rod 251 is hinged to the movable bar 192 through a connecting rod 193, and the connecting rod 193 is hinged to the swing rod 251 and the movable bar 192 through the rotating shafts provided at both ends.

[0052] The working principle of the above-mentioned material blocking bar is: the material blocking bar will block the medicine on the rotating disk 12. When the push block 17 contacts the lever 25, the lever 25 will drive the swing rod 251 to swing when it rotates. The swing rod 251 will pull the movable bar 192 to swing through the connecting rod 193, so that the movable bar 192 will gather the medicine on the outside to the middle. When the hopper 16 passes by, the medicine will fall into the hopper 16.

[0053] Example 4: Fig.12 , Fig.13 As shown, this embodiment is basically the same as Example 1, except that a spiral plate 26 is provided on the bottom surface of the discharge tank 2, and a knocking mechanism is provided on the bottom surface of the discharge tank 2 for knocking the spiral plate 26 by rotating the torsion plate 23, the knocking mechanism includes a movable frame 28 vertically slidably arranged on the bottom surface of the discharge tank 2, and a slide rod 27 horizontally slidably arranged on the left partition and located in the movable frame 28; the movable frame 28 is connected to the bottom surface of the discharge tank 2 through a spring, the movable frame 28 is slidably connected to the slide rod provided on the bottom surface of the discharge tank 2, the spring is sleeved on the slide rod, and a knocking column 281 in contact with the spiral plate 26 is provided on the upper end of the movable frame 28, the slide rod 27 is connected to the side wall of the arc-shaped partition bin 22 through an air bag 272, a fixing ring is sleeved on the slide rod 27, the air bag is sleeved on the slide rod 27 between the fixing ring and the side wall of the arc-shaped partition bin 22, and three convex columns 271 are provided on the side wall of the slide rod 27 for pushing the movable frame 28 up and down by sliding.

[0054] The working principle of the above-mentioned knocking mechanism is: when the torsion plate 24 rotates counterclockwise, the torsion plate 24 will contact and squeeze the sliding rod 27, causing the sliding rod 27 to slide to the left. When the sliding rod 27 slides to the left, the protruding column 271 will intermittently squeeze the movable frame 28, causing the movable frame 28 to reciprocate and rise and fall to knock on the spiral plate 26, causing the spiral plate 26 to vibrate.
