Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment dosing technology, specifically a gravity flow automated dosing device. Background Technology

[0002] In wastewater treatment and other fields, dosing devices are one of the key pieces of equipment for achieving water purification. Currently, the addition of chemicals such as polyferric sulfate in wastewater treatment is mostly done by metering pumps, which are injected into high-density clarification tanks through pipelines.

[0003] However, this method has obvious drawbacks: polyferric sulfate solution has a certain viscosity, and when transported through pipelines for a long time, it is very easy to form sediment and accumulate on the inner wall of the pipeline, leading to pipeline blockage. Once blockage occurs, the agent cannot be injected into the treatment system in time, which not only affects the sewage treatment effect, but may also increase maintenance costs and labor time due to shutdown to clear the pipeline. To solve the pipeline blockage problem, the industry has tried to adopt gravity flow dosing method, that is, pressurizing the agent preparation tank and using the pressure difference to make the solution flow naturally to the treatment device.

[0004] However, in practical applications, new problems arise. During the preparation and storage of polyferric sulfate solution, due to the slow addition rate and long settling time, the solute is prone to precipitate at the bottom of the tank. The formation of precipitation not only reduces the uniformity of solution concentration and affects the accuracy of subsequent reagent dosing, but may also reduce the effective volume of the tank due to precipitation accumulation, thereby reducing the overall operating efficiency of the dosing device.

[0005] Therefore, an automated gravity flow dosing device is proposed. Utility Model Content

[0030] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0033] Example 1:

[0034] Please see Figure 1 - Figure 5 This is the first embodiment of the present invention.

[0035] This embodiment provides an automated gravity flow dosing device, including:

[0036] Tank 1;

[0037] Top plate 2 is fixedly installed on the top of tank body 1;

[0038] The stirring assembly 4 is located at the bottom of the top plate 2 and on the inner side of the tank body 1.

[0039] Drive motor 3 is fixedly installed on the top of top plate 2. Drive motor 3 is used to drive the stirring assembly 4 to rotate.

[0040] The pressurizer 5 is located on one side of the tank 1. A second one-way valve 13 is fixedly installed at the output end of the pressurizer 5. An air pipe 14 is fixedly installed at the output end of the second one-way valve 13. The output end of the air pipe 14 is fixedly installed inside one side of the tank 1.

[0041] For example, the stirring assembly 4 includes a driving gear 41, a plurality of driven gears 42, a plurality of rotating shafts 43 and a plurality of stirring blades 44. The driving gear 41 is fixedly installed at the output end of the drive motor 3. The plurality of driven gears 42 are all meshed with the side of the driving gear 41. The plurality of rotating shafts 43 are respectively fixedly installed inside the plurality of driven gears 42. The plurality of stirring blades 44 are respectively fixedly installed on the outer side of the plurality of rotating shafts 43. The top of the plurality of rotating shafts 43 is rotatably connected to the bottom of the top plate 2.

[0042] Furthermore, the meshing design of the drive gear 41 and multiple driven gears 42 allows multiple sets of stirring blades 44 to rotate synchronously through a single drive motor 3, expanding the stirring range and enhancing the stirring intensity, effectively suppressing solute precipitation; the rotational connection between the rotating shaft 43 and the top plate 2 ensures the stability of the stirring process; there is one drive gear 41 and four driven gears 42.

[0043] For example, an observation window 7 is fixedly installed on the front of the tank body 1, and a support frame 8 is fixedly installed on the bottom of the tank body 1.

[0044] Furthermore, the observation window 7 facilitates real-time monitoring of the liquid level and mixing state of the solution inside the tank 1, while the support frame 8 provides stable support for the tank 1, preventing displacement due to vibration during device operation.

[0045] For example, a liquid outlet valve 9 is fixedly installed at the bottom of the tank body 1, and a liquid outlet pipe 10 is fixedly installed at the output end of the liquid outlet valve 9.

[0046] Furthermore, the liquid outlet valve 9 can control the dosing flow rate and, together with the pressure regulation of the pressurizer 5, achieve precise dosing; the liquid outlet pipe 10 serves as a gravity flow transport channel and is directly connected to the treatment device, reducing the risk of pipeline blockage.

[0047] For example, an inlet pipe 11 is fixedly installed inside the top of the other side of the tank body 1, and a first one-way valve 12 is fixedly installed at the input end of the inlet pipe 11.

[0048] Furthermore, the inlet pipe 11 is used to replenish the tank 1 with medicine or water. The first one-way valve 12 can prevent the liquid from flowing back into the inlet pipe 11 when the tank 1 is pressurized, thus ensuring the safety of the feeding system.

[0049] In use, reagents (such as polyferric sulfate solution) or water are injected into tank 1 through inlet pipe 11. The first one-way valve 12 prevents liquid from flowing back into inlet pipe 11 when pressurized in tank 1, ensuring the safety of the feeding system. Then, the drive motor 3 is started, and its output drives the drive gear 41 to rotate. The drive gear 41 meshes with multiple driven gears 42, thereby driving multiple rotating shafts 43 to rotate synchronously. This causes the stirring blades 44 fixed on the rotating shafts 43 to fully stir the solution in the tank, preventing solute precipitation. After that, the pressurizer is started. 5. Gas is injected into tank 1 through gas pipe 14 to increase the pressure inside the tank. The second one-way valve 13 can prevent gas from leaking back. When adding chemicals later, the outlet valve 9 is opened. Under the action of pressure difference, the solution is transported to the treatment device (such as a high-density clarifier) ​​by gravity flow through outlet pipe 10 to realize the addition of chemicals. When using the device later, the user can monitor the liquid level and mixing state of the solution in the tank in real time through observation window 7. The support frame 8 provides stable support for tank 1 to prevent displacement due to vibration during operation.

[0050] In summary, through the coordinated operation of the tank 1, drive motor 3, and stirring assembly 4, the drive motor 3 enables the stirring assembly 4 to work in concert with the drive gear 41, driven gear 42, rotating shaft 43, and stirring blades 44 to thoroughly and comprehensively stir the polyferric sulfate and other reagent solutions within the tank 1. This effectively solves the problem of solute precipitation at the bottom of the tank 1 caused by slow solution addition and long settling time during reagent preparation and storage. It avoids precipitation reducing the uniformity of solution concentration, affecting the accuracy of reagent dosing, and reducing the effective volume of the tank 1 and the operating efficiency of the device. This ensures the consistency of solution concentration and improves the overall operating efficiency of the dosing device.

[0051] Example 2:

[0052] Please see Figure 1 - Figure 3 This is the second embodiment of the present utility model.

[0053] For example, an arc-shaped filter cover 15 is fixedly installed on the inner side of the tank body 1, and the arc-shaped filter cover 15 is disposed at the bottom of the stirring assembly 4.

[0054] Furthermore, the arc-shaped filter cover 15 located at the bottom of the stirring assembly 4 can filter out large particulate impurities that may be present in the solution, preventing impurities from entering the outlet pipe 10 with the solution and causing blockage, while not affecting the normal operation of the stirring assembly.

[0055] For example, the bottom of the press 5 is provided with a mounting assembly 6, which includes a mounting plate 61 and a reinforcing rod 62. The top of the mounting plate 61 is fixedly mounted to the bottom of the press 5, and the reinforcing rod 62 is fixedly mounted to the bottom of the mounting plate 61. The side of the mounting plate 61 and one end of the reinforcing rod 62 are both fixedly mounted to one side of the tank 1.

[0056] Furthermore, the combination of mounting plate 61 and reinforcing rod 62 securely fixes the pressurizer 5 to the side of tank 1. The reinforcing rod 62 enhances the load-bearing capacity of the mounting structure and prevents the pressurizer 5 from loosening due to vibration during operation.

[0057] During use, the stirred solution flows to the outlet pipe 10 and passes through the arc-shaped filter cover 15 located at the bottom of the stirring assembly 4 to filter out large particles of impurities that may exist in the solution, so as to prevent impurities from entering the outlet pipe 10 and causing blockage.

[0058] The pressurizer 5 is firmly fixed to the side of the tank 1 by the mounting assembly 6. The mounting plate 61 bears the weight of the pressurizer 5, and the reinforcing rod 62 enhances the load-bearing capacity of the mounting structure, preventing the pressurizer 5 from loosening due to vibration during operation and ensuring the stability of the pressurization process.

[0059] In summary, the arc-shaped filter cover 15 can filter large particulate impurities during use, further reducing the risk of blockage in the liquid outlet pipe. Combined with gravity flow dosing, it significantly reduces pipeline maintenance costs and downtime. The installation component 6 can firmly connect the compressor 5 to the tank 1 during use, preventing vibration of the compressor 5 from affecting the overall stability of the device and extending the service life of the equipment.
