Description

Technical Field

[0001] The invention relates to the technical field of water pollution prevention and control agents, in particular to a scale and corrosion inhibitor dosing device. Background Art

[0002] At the same time, it is necessary to add scale inhibitors and corrosion inhibitors to the sewage treatment pool. Scale inhibitors and corrosion inhibitors are usually composed of organic phosphine, high-quality copolymers and copper corrosion inhibitors. At the same time, scale inhibitors and corrosion inhibitors are water pollution prevention and control agents. They are mainly used to prevent the crystallization and precipitation of insoluble inorganic salts in water, thereby protecting water treatment equipment and pipelines from scaling and blockage. In some small sewage treatment stations, no dosing device is configured, and some granular or slow-release tablets and scale inhibitors are designed for direct addition. At the same time, anaerobic tanks, sludge concentration tanks and other water tanks with poor fluidity often use direct spraying of scale inhibitors, so that the scale inhibitors can slowly diffuse and adsorb on the scaling surface to play a long-term role. Direct spraying of scale inhibitors and corrosion inhibitors is mostly done manually, and manual dosing will result in inaccurate metering. Domestic sewage contains a large amount of organic matter, microorganisms, as well as phosphorus and surfactants brought by detergent residues. Under such conditions, the calcium and magnesium ions in the water can easily combine with carbonate and sulfate ions to form hard scale, which adheres to the wall of the treatment pool. Therefore, it is necessary to add scale and corrosion inhibitors to chelate the calcium and magnesium ions in the water to prevent the formation of scale.

[0003] In traditional sewage treatment pools, the weight of sewage that needs to be treated in different batches is also different. If the weight of the treated sewage is large, the amount of scale inhibitor and corrosion inhibitor needs to be increased. The traditional scale inhibitor and corrosion inhibitor dosing device adopts a direct dumping method to add the scale inhibitor and corrosion inhibitor, which cannot ensure that the scale inhibitor and corrosion inhibitor can cover a sufficient amount of water. When the weight of the treated sewage is small, excessive amount of scale inhibitor and corrosion inhibitor will result in waste of scale inhibitor and corrosion inhibitor. At the same time, the scale inhibitor and corrosion inhibitor cannot be effectively inhibited due to insufficient amount of scale inhibitor and corrosion inhibitor.

[0004] At the same time, the traditional pouring of scale inhibitors and corrosion inhibitors cannot ensure their uniform diffusion in the water pollution treatment pool, resulting in local concentrations that are too high or too low in the water pollution treatment pool, thereby reducing the scale treatment effect. At the same time, direct dumping will cause the problem of scale inhibitor deposition, so that the scale inhibitors and corrosion inhibitors will accumulate at the bottom of the pool, thereby reducing the utilization rate of the scale inhibitors and corrosion inhibitors.

[0005] Therefore, a scale and corrosion inhibitor dosing device is proposed. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0042] A buffer assembly is provided inside the water pollution treatment tank 1, and the buffer assembly includes a spring 3 fixedly connected to the bottom of the inner cavity of the water pollution treatment tank 1. The side wall of the water pollution treatment tank 1 is symmetrically threaded with a connecting plate 4. Four groups of torsion springs 51 are installed on the side of the two connecting plates 4 close to the spring 3, and each group of torsion springs 51 is provided with no less than two. A rotating plate 52 is fixedly connected between each group of torsion springs 51, and the rotating plate 52 is rotatably connected to the side wall of the connecting plate 4. A sliding basin 6 is fixedly connected to the top of the spring 3. The sliding basin 6 is used to accommodate sewage, and each group of torsion springs 51 can withstand the weight of sewage of different weights in sequence in a vertical downward order, and the weight of the sewage borne by the torsion spring 51 increases in sequence. The sliding basin 6 is slidably adapted to the inner cavity of the water pollution treatment tank 1, and each rotating plate 52 is located on the movement path of the sliding basin 6. The top of the sliding basin 6 is fixedly connected to the bottom of the connecting column 7, and the top of the sliding basin 6 is fixedly connected to the bottom of the connecting column 7.

[0043] The multi-stage feeding assembly also includes an arc-shaped groove 14 opened on the lower surface of the circular sleeve 9, and the bottom of the collecting cylinder 11 is fixedly connected to a fixed block 15. The end of the fixed block 15 away from the collecting cylinder 11 is rotatably connected to a connecting rod 16. The arc-shaped groove 14 is located on the movement path of the connecting rod 16. The connecting rod 16 and the lower surface of the circular sleeve 9 conflict with each other. The end of the connecting rod 16 away from the circular sleeve 9 is fixedly connected to a round cover 17. When the end of the connecting rod 16 away from the round cover 17 is placed in the arc-shaped groove 14, the end of the connecting rod 16 away from the round cover 17 increases the upward range of movement so that the round cover 17 rotates downward with the fixed block 15 as the axis. The size of the round cover 17 is adapted to the size of the collecting tube 11. An annular groove 18 is provided on the top of the umbrella-shaped delivery block 12. Circular holes 19 are symmetrically provided inside the annular groove 18. The circular hole 19 is communicated with the top of the delivery tube 13. A gear 20 is fixedly connected to the bottom of the umbrella-shaped delivery block 12. A stepper motor 21 is fixedly connected to the upper surface of the fixed horizontal plate 2. An incomplete gear 22 is fixedly connected to the output shaft end of the stepper motor 21. The part of the incomplete gear 22 containing the tooth block is meshed with the gear 20, and the number of tooth blocks of the incomplete gear 22 is one-fourth the number of tooth blocks of the gear 20.

[0044] A swing assembly is provided on the fixed horizontal plate 2, and the swing assembly includes a gear 2 23 which penetrates and is fixedly connected to the output shaft end of the stepper motor 21.

Gear 2 23 and gear 3 25 are meshed with each other, and the gap between adjacent tooth blocks of gear 2 23 is twice that of gear 3 25, so that gear 3 25 can rotate two circles when gear 2 23 rotates one circle, thereby making the L-shaped pipe 24 rotate faster. A funnel 26 is fixedly connected to the top of the L-shaped pipe 24.

[0045] A storage barrel 27 is fixedly connected to the top of the fixed horizontal plate 2, and the upper part of the storage barrel 27 is located on the movement trajectory of the circular hole 19. Scale inhibitors and corrosion inhibitors are stored inside the storage barrel 27. The components of the scale inhibitors and corrosion inhibitors are organic phosphonic acids and polycarboxylic acids. The function of organic phosphonic acids is to chelate calcium and magnesium ions and inhibit the formation of scale such as calcium carbonate and calcium sulfate. The function of polycarboxylic acids is to disperse the formed scale particles and prevent their deposition. This is the existing technology and will not be elaborated here. The bottom of the storage barrel 27 is fixedly connected to a delivery pipe 28. The bottom of the delivery pipe 28 is slidably adapted to the annular groove 18, and the size of the delivery pipe 28 is adapted to the size of the circular hole 19. The delivery pipe 28 is located on the movement path of the circular hole 19.

[0046] The above implementation works as follows:

[0047] The initialization steps are as follows:

[0048] Sewage that needs to be treated is injected into the water pollution treatment tank 1 , and the sewage enters the inner cavity of the water pollution treatment tank 1 and reaches the sliding basin 6 .

[0049] The steps for running the job are as follows:

[0050] The buffering component works as follows:

[0051] When the sewage to be treated pushes the sliding basin 6 to slide vertically downward in the inner cavity of the water pollution treatment tank 1 due to its own weight, the sliding basin 6 moves vertically downward and pushes the spring 3 to start compressing. Similarly, the sliding basin 6 slides vertically downward and makes its bottom contact with the rotating plate 52. If the weight of the sewage to be treated this time is not enough to deform the torsion spring 51 at the highest point in the vertical direction, the weight of the sewage to be treated at this time will no longer push the spring 3 to continue moving downward, and the sliding basin 6 will be limited by the two rotating plates 52 and will no longer continue to move vertically downward. If the weight of the sewage to be treated this time causes the torsion spring 51 at the highest point in the vertical direction to deform, the weight of the sewage to be treated at this time will continue to push the spring 3 to move vertically downward, and the sliding basin 6 will squeeze The connection between the two rotating plates 52 and the torsion spring 51 is axially rotated close to the side wall of the water pollution treatment tank 1, so that the sliding basin 6 continues to slide vertically downward on the inner wall of the water pollution treatment tank 1, so that the sliding basin 6 contacts the two rotating plates 52 located second in the vertical direction. If the weight of the sewage to be treated this time is not enough to cause the torsion spring 51 located second in the vertical direction to deform, the sliding basin 6 is limited by the two rotating plates 52 located second in the vertical direction and no longer continues to move vertically downward. At this time, the weight of the sewage to be treated no longer pushes the spring 3 to continue to move downward, and the two rotating plates 52 located third and fourth in the vertical direction repeat the above working process, thereby realizing that the sliding basin 6 can be lowered a certain distance vertically according to the weight of different sewage.

[0052] At the same time, when the sliding basin 6 slides vertically downward to the second, third or fourth rotating plate 52, the side wall of the sliding basin 6 always contacts the rotating plate 52 that has been rotating. Therefore, after the sewage treatment is completed, when the sewage in the sliding basin 6 is transferred out of its inner cavity, the spring 3 pushes the emptied sliding basin 6 to slide vertically upward in the water pollution treatment tank 1 through the elastic stretching force, thereby realizing the reset of the sliding basin 6 and preparing for the next sewage treatment.

[0053] The working principle of the multi-stage feeding component is as follows:

[0054] After each sewage treatment, the water pollution treatment pool 1 needs to drain the treated sewage, and then wait for the next sewage to be treated to be injected into the inner cavity of the water pollution treatment pool 1. Therefore, when the weight of the sewage to be treated is different each time, the distance that the sliding basin 6 slides vertically downward in the water pollution treatment pool 1 is also different. At the same time, in view of the different weights of the sewage put into the inner cavity of the sliding basin 6 multiple times, when determining the weight of each sewage input, if the four sets of torsion springs 51 on the connecting plate 4 cannot bear the weight of the sewage, the staff can replace the different connecting plates 4 by twisting the bolts between the connecting plate 4 and the water pollution treatment pool 1. The deformation torque borne by each set of torsion springs 51 on the different connecting plates 4 is also different, thereby meeting the requirements of sewage weight changes in multiple sewage treatments.

[0055] If the sewage to be treated next time is heavier than the last time, the distance that the sliding basin 6 slides vertically downward in the inner cavity of the water pollution treatment tank 1 will be greater. Similarly, each time the sewage to be treated enters the water pollution treatment tank 1, the sliding basin 6 will be driven to slide vertically downward in the inner cavity of the water pollution treatment tank 1. Therefore, the vertical downward sliding of the sliding basin 6 drives the connecting column 1 7 to move vertically downward synchronously, and the connecting column 1 7 drives the connecting column 2 8 to move vertically downward as well. Therefore, the connecting column 2 8 drives the circular sleeve 9 to move synchronously, and then the connecting column 2 8 drives the umbrella-shaped adjusting block 10 to move vertically downward, and the umbrella-shaped adjusting block 10 drives the collecting cylinder 11 to slide vertically downward on the outside of the feeding cylinder 13, so that it is close to the storage The collecting cylinder 11 and the round cover 17 on one side of the barrel 27 both move vertically downward. At the same time, the connecting rod 16 close to the side of the storage barrel 27 always contacts the lower surface of the circular sleeve 9 and does not pass through the arc surface of the arc-shaped groove 14. Therefore, the round cover 17 covers the bottom of the collecting cylinder 11. When the collecting cylinder 11 slides vertically downward to the outside of the delivery cylinder 13, the delivery cylinder 13 and the distance that the collecting cylinder 11 slides out of the delivery cylinder 13 form a new enclosed space. Therefore, in summary, according to the different weights of sewage, the distance that the sliding basin 6 slides vertically downward in the water pollution treatment tank 1 is also different, that is, the heavier the water weight, the larger the new enclosed space, and thus the heavier the water weight, the more scale inhibitor and corrosion inhibitor needs to be delivered.

[0056] As mentioned above, when the sliding basin 6 tends to be stationary and no longer moves vertically downward, the output shaft end of the stepping motor 21 drives the incomplete gear 22 to rotate clockwise after being energized. Therefore, the incomplete gear 22 continues to rotate clockwise at the shaft connected to the stepping motor 21. When the toothed portion of the incomplete gear 22 drives the gear 1 20 meshing with it to rotate counterclockwise, when the incomplete gear 22 rotates one circle, the gear 1 20 rotates a quarter circle. When the gear 1 20 rotates a quarter circle, the gear 1 20 drives the umbrella-shaped delivery block 12 to rotate synchronously. The umbrella-shaped delivery block 12 drives the annular groove 18 opened thereon to slide on the outer wall of the delivery pipe 28. At the same time, the circular hole 19 rotates to coincide with the delivery pipe 28. Therefore, the scale inhibitor and corrosion inhibitor inside the storage barrel 27 enters the circular hole 19 through the delivery pipe 28, and at the same time, the scale inhibitor and corrosion inhibitor inside the storage barrel 27 enters the circular hole 19 through the delivery pipe 28. The scale and corrosion inhibitor enters the delivery tube 13 through the circular hole 19 again, and finally falls onto the upper surface of the round cover 17. When the incomplete gear 22 rotates one circle again, the gear 20 continues to rotate a quarter of a circle, so the new enclosed space is filled with scale and corrosion inhibitor. At the same time, the delivery pipe 28 is blocked by the annular groove 18 and no longer delivers scale and corrosion inhibitor. Then the incomplete gear 22 rotates one circle again. At this time, the connecting rod 16 is placed in the arc groove 14, so that the space for the end of the connecting rod 16 away from the round cover 17 to move upward increases, and then the connecting rod 16 uses the fixed block 15 as the axis to move the end of the connecting rod 16 away from the round cover 17 upward, and the round cover 17 moves downward, so that the round cover 17 no longer covers the bottom end of the collecting tube 11, so that the scale and corrosion inhibitor in the new enclosed space begins to fall along the round cover 17 due to its own gravity.

[0057] Therefore, different water weights require different scale and corrosion inhibitors. The heavier the water weight, the more scale and corrosion inhibitors it requires.

[0058] The arrangement in which the buffer component and the multi-stage feeding component cooperate with each other can add scale inhibitors and corrosion inhibitors according to the weight of the sewage to be treated in the inner cavity of the water pollution treatment tank 1. When the weight of the treated sewage increases, the amount of scale inhibitors and corrosion inhibitors added is automatically increased to ensure that the scale inhibitors and corrosion inhibitors cover a sufficient amount of water; when the weight of the treated sewage decreases, the amount of scale inhibitors and corrosion inhibitors added is reduced to avoid waste of scale inhibitors and corrosion inhibitors. At the same time, it also avoids the situation where scale inhibition and corrosion inhibition cannot be effectively achieved due to insufficient amount of scale inhibitors and corrosion inhibitors.

[0059] The arrangement of the incomplete gear 22 and the gear 2 23 in the multi-stage feeding assembly enables quantitative feeding of the scale inhibitor and corrosion inhibitor after the feeding amount is determined, and also stops feeding the scale inhibitor and corrosion inhibitor after feeding, so as to facilitate the treatment of water pollution in the inner cavity of the water pollution treatment tank 1 next time, thereby saving the step of manually adding scale inhibitor and corrosion inhibitor every time the staff performs water pollution treatment.

[0060] The working principle of the swing assembly is as follows:

[0061] As mentioned above, when the stepper motor 21 is powered on and drives the incomplete gear 22 to rotate three circles, the scale inhibitor and corrosion inhibitor in the newly enclosed space begins to fall along the round cover 17 due to its own gravity, and the scale inhibitor and corrosion inhibitor falls into the funnel 26. Because the output shaft of the stepper motor 21 drives the gear 2 23 to rotate, the gear 2 23 drives the gear 3 25 meshing with it to rotate synchronously. At this moment, the scale inhibitor and corrosion inhibitor smoothly enters the L-shaped pipe 24 along the funnel 26. At the same time, the rotation of the gear 3 25 drives the scale inhibitor and corrosion inhibitor to enter the L-shaped pipe 24 smoothly. The L-shaped pipe 24 rotates with the connection between the L-shaped pipe 24 and the fixed horizontal plate 2 as the center of the circle, so the bottom of the L-shaped pipe 24 performs a circular motion with the connection between the L-shaped pipe 24 and the fixed horizontal plate 2 as the center of the circle, that is, the scale and corrosion inhibitor is thrown out of the inner cavity of the L-shaped pipe 24 when it passes through the bottom of the L-shaped pipe 24. At the same time, when the stepping motor 21 is energized to drive the incomplete gear 22 to rotate one circle again, the gear 1 20 rotates a total of four circles at this time, that is, the umbrella-shaped delivery block 12 rotates 360 degrees, and thus returns to the initial position again.

[0062] When the scale inhibitor is thrown into the water in the inner cavity of the water pollution treatment tank 1, the scale inhibitor chelates the calcium and magnesium ions in the water, inhibiting the formation of scale such as calcium carbonate and calcium sulfate, thereby preventing water pollution caused by scale.

[0063] The setting of the swing component can throw the scale inhibitor and corrosion inhibitor into the water pollution treatment tank 1, so that the sewage to be treated in the water pollution treatment tank 1 can contact the scale inhibitor and corrosion inhibitor in different areas. Therefore, the circular motion can make the scale inhibitor and corrosion inhibitor diffuse more evenly in the water pollution treatment tank 1, avoiding the local concentration in the water pollution treatment tank 1 being too high or too low, thereby improving the scale treatment effect, and at the same time reducing the problem of scale inhibitor and corrosion inhibitor deposition caused by direct dumping, thereby avoiding the accumulation of scale inhibitor and corrosion inhibitor at the bottom of the tank, thereby improving the utilization rate of the scale inhibitor and corrosion inhibitor.

[0064] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
