Description

Technical Field

[0001] This utility model belongs to the technical field of water treatment equipment, and in particular relates to a chemical reagent metering and dosing device for removing excess manganese ions from water in water plants. Background Technology

[0002] Manganese is a common harmful heavy metal element in water bodies. Excessive manganese can lead to problems such as yellowing water and scaling in pipes. Currently, water plants mostly use chemical oxidation to remove manganese. This involves adding oxidants such as potassium permanganate powder to the raw water tank to convert dissolved divalent manganese into insoluble MnO2, which is then removed by precipitation.

[0003] However, insufficient addition of potassium permanganate powder will lead to incomplete manganese removal, while excessive addition will result in too much MnO2 suspended matter residue in the raw water tank, increasing treatment costs. Therefore, in order to ensure that the amount of potassium permanganate powder added each time is the same, operators must weigh the potassium permanganate powder before adding it, which increases working time and labor costs and reduces the manganese removal efficiency of the water plant. Utility Model Content

[0004] The purpose of this invention is to achieve automatic loading and unloading by using a telescopic push rod motor to drive the metering barrel to move, thereby solving the problem in the background art where potassium permanganate powder needs to be manually weighed and added, which is time-consuming and labor-intensive and reduces the manganese removal efficiency of water plants.

[0005] The specific technical solution of this utility model is as follows: A manganese removal metering device for a water plant includes a base, a mounting plate vertically mounted on the top of the base, a telescopic push rod motor mounted on the front face of the mounting plate, the telescopic push rod motor having a push rod, a connecting plate located on the top of the mounting plate, a linear through groove located on the connecting plate and along the direction of the push rod, a connector located on the top of the connecting plate, and a discharge bucket connected to the top of the connector; a limiting collar is provided at the front end of the push rod, a metering bucket is adapted to fit inside the limiting collar, a first blocking slide plate is fixedly fitted on the upper part of the metering bucket, the first blocking slide plate is slidably connected to the linear through groove, the upper surface of the metering bucket is flush with the upper surface of the first blocking slide plate, the lower surface of the metering bucket is in contact with the upper surface of the base, and the upper surface of the first blocking slide plate is in contact with the lower surface of the connector.

[0006] Furthermore, the connector is threaded to the discharge bucket, and several operating levers are provided around the outer surface of the discharge bucket, with anti-slip textures on the surface of the operating levers.

[0007] Furthermore, the discharge hopper is equipped with a sealing cover, which is threadedly connected to the discharge hopper, and the sealing cover is equipped with a handwheel.

[0008] Furthermore, a sealing gasket is provided at the contact point between the sealing cap and the upper surface of the discharge hopper.

[0009] Furthermore, several mounting holes are provided on the base.

[0010] Furthermore, a clamping component is bolted to the front end of the base, a first concave arc is provided on the front surface of the base, and a second concave arc is provided on the rear surface of the clamping component to match the first concave arc.

[0011] Furthermore, a second shielding slide is fixedly fitted at the lower part of the measuring barrel, and the lower surface of the measuring barrel is flush with the lower surface of the second shielding slide.

[0012] Furthermore, the upper surface of the base is provided with a second linear groove, and the lower surface of the second shielding slide is provided with a second slide bar that is adapted to the second linear groove.

[0013] Furthermore, the inner surfaces on both sides of the linear through groove are provided with a first linear sliding groove, and the inner surfaces on both sides of the first shielding slide are provided with a first sliding strip adapted to the first linear sliding groove.

[0014] Furthermore, the bottom of the discharge hopper is an inverted cone shape.

[0015] Compared with the prior art, the present invention has the following beneficial effects: First, pour potassium permanganate powder into the discharge bucket and seal it. The powder will then leak into the metering bucket, filling it completely. When more potassium permanganate is needed, control the telescopic pusher motor to push the metering bucket. As the bottom of the metering bucket slides out of the base, the powder will automatically fall into the raw water tank due to gravity. Then, control the telescopic pusher motor to pull the metering bucket back onto the base, aligning the top of the metering bucket with the bottom of the discharge bucket. The powder will then leak back into the metering bucket for refilling, preparing for the next addition. The entire process eliminates the need for manual weighing, ensuring the same amount is added each time. This saves time, improves the efficiency of manganese removal in the water plant, reduces labor costs, and eliminates the need for manual weighing, thus reducing operator contact with the powder and minimizing potential harm.

[0017] To better understand the purpose, structure, and function of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0018] See Figures 1 to 6This embodiment discloses a manganese removal metering device for a water plant, including a base 1. A mounting plate 11 is vertically mounted on the top of the base 1. A telescopic push rod motor 2 is mounted on the front surface of the mounting plate 11. The telescopic push rod motor 2 has a push rod 21. A connecting plate 12 is located on the top of the mounting plate 11. A linear through groove 121 is located on the connecting plate 12 and runs parallel to the push rod 21. A connector 13 is located on the top of the connecting plate 12. A discharge bucket 4 is connected to the top of the connector 13 to hold potassium permanganate powder. The connector 13 has a tubular structure, allowing the potassium permanganate powder in the discharge bucket 4 to leak into the metering bucket 3 through the connector 13. The capacity of the discharge bucket 4 is greater than the capacity of the metering bucket 3, allowing for the metering bucket to receive more potassium permanganate powder. 3. Multiple feeding operations improve feeding efficiency. Connector 13 is threadedly connected to the feeding bucket 4, facilitating easy installation and disassembly when the feeding bucket 4 needs maintenance or replacement. Several operating levers 41 are circumferentially located on the outer surface of the feeding bucket 4, facilitating the twisting operation when installing or removing the feeding bucket 4. The surface of the operating levers 41 is textured to prevent slippage during operation. The feeding bucket 4 is equipped with a sealing cover 42 to prevent the potassium permanganate powder inside the feeding bucket 4 from being contaminated by the external environment. The sealing cover 42 is threadedly connected to the feeding bucket 4, facilitating the removal of the sealing cover 42 when feeding bucket 4 needs to be added. The sealing cover 42 is equipped with a handwheel 421, making it easier for operators to remove the sealing cover 42. The contact portion between the sealing cover 42 and the upper surface of the feeding bucket 4... A sealing gasket made of PTFE is provided at the position, which is oxidation resistant and prevents corrosion by potassium permanganate powder. A limiting collar 22 is provided at the front end of the push rod 21, and a metering barrel 3 is fitted inside the limiting collar 22. The metering barrel 3 is a tubular structure with openings at both the top and bottom. A first blocking slide plate 31 is fixedly fitted on the upper part of the metering barrel 3. When the metering barrel 3 is pushed so that its bottom opening leaves the base 1, the first blocking slide plate 31 can block the bottom opening of the connector 13, preventing potassium permanganate powder from leaking out of the discharge barrel 4. The first blocking slide plate 31 is slidably connected to the linear channel 121. The inner surfaces of both sides of the linear channel 121 are provided with first linear grooves 122 facing each other. The inner surfaces of the first blocking slide plate 31 are also provided with first linear grooves 122 facing each other. The sliding cooperation between the first sliding bar 311, the first linear groove 122 and the first sliding bar 311 makes the position of the first blocking slide plate 31 more stable when it slides in the linear groove 121. The upper surface of the metering barrel 3 is flush with the upper surface of the first blocking slide plate 31, and the lower surface of the metering barrel 3 is in contact with the upper surface of the base 1. When the metering barrel 3 is at the bottom of the discharge barrel 4 for feeding, the base 1 can seal the bottom opening of the metering barrel 3 to prevent the potassium permanganate powder in the metering barrel 3 from leaking out. The upper surface of the first blocking slide plate 31 is in contact with the lower surface of the connector 13. When the metering barrel 3 is pushed so that its bottom opening leaves the base 1, the first blocking slide plate 31 can block the bottom opening of the connector 13 to prevent the potassium permanganate powder in the discharge barrel 4 from leaking out.

[0019] The telescopic push rod motor 2 pushes the metering barrel 3. When the bottom opening of the metering barrel 3 slides out of the base 1, the first blocking slide plate 31 will block the bottom opening of the connector 13 to prevent the potassium permanganate powder in the discharge barrel 4 from leaking out. At this time, the potassium permanganate powder in the metering barrel 3 will automatically fall into the raw water pool due to gravity. Then, the telescopic push rod motor 2 is controlled to pull the metering barrel 3 back to the base 1 until the top opening of the metering barrel 3 is aligned with the bottom opening of the discharge barrel 4. The base 1 can seal the bottom opening of the metering barrel 3 to prevent the potassium permanganate powder in the metering barrel 3 from leaking out. At this time, the potassium permanganate powder in the discharge barrel 4 will leak back into the metering barrel 3 for refilling, preparing for the next addition of potassium permanganate powder. The amount added each time is the same, and there is no need for manual weighing. This embodiment can be further optimized by equipping the telescopic push rod motor 2 with a PLC controller, which controls the stroke of the push rod 21 to achieve the alignment of the upper opening of the metering barrel 3 with the bottom opening of the dispensing barrel 4 and the movement of the bottom opening of the metering barrel 3 sliding out of the base 1.

[0020] The base 1 has several mounting holes 14, which can be used to fix the entire device next to the original water tank.

[0021] See Figure 5 The base 1 is connected to a clamping member 6 at its front end by bolts 5. The front surface of the base 1 has a first concave arc 15, and the rear surface of the clamping member 6 has a second concave arc 61 that matches the first concave arc 15. By tightening the bolts 5, a feeding tube can be clamped by the base 1 and the clamping member 6. The length of the feeding tube is selected so that its bottom opening can be close to the water surface. The potassium permanganate powder in the metering tank 3 is added to the raw water tank through the feeding tube. This can prevent the potassium permanganate powder from flying away during the falling process when the metering tank 3 is at a high height above the water surface, causing waste and polluting the environment. The length of the feeding tube can be selected according to the distance between the metering tank 3 and the water surface. The cooperation between the first concave arc 15 and the second concave arc 61 can make the base 1 and the clamping member 6 fit against the outer wall of the feeding tube, making the clamping more secure.

[0022] The lower part of the measuring barrel 3 is fixedly fitted with a second shielding slide plate 32. The lower surface of the measuring barrel 3 is flush with the lower surface of the second shielding slide plate 32. The upper surface of the base 1 is provided with a second linear slide groove 16. The lower surface of the second shielding slide plate 32 is provided with a second slide bar 321 that is adapted to the second linear slide groove 16. Through the sliding cooperation between the second linear slide groove 16 and the second slide bar 321, the second shielding slide plate 32 and the base 1 are slidably connected, making the second shielding slide plate 32 slide more smoothly.

[0023] The bottom of the discharge hopper 4 is inverted conical, which facilitates the sliding of potassium permanganate powder into the metering hopper 3.

[0024] Working principle: First, potassium permanganate powder is poured into the discharge bucket 4 and the sealing cap 42 is closed. At this time, the potassium permanganate powder in the discharge bucket 4 will leak into the metering bucket 3, filling the metering bucket 3. When potassium permanganate powder needs to be added, the telescopic push rod motor 2 is controlled to push the metering bucket 3. When the bottom opening of the metering bucket 3 slides out of the base 1, the potassium permanganate powder in the metering bucket 3 will automatically fall into the raw water pool due to gravity. Then, the telescopic push rod motor 2 is controlled to pull the metering bucket 3 back onto the base 1. At this time, the top opening of the metering bucket 3 is aligned with the bottom opening of the discharge bucket 4, and the potassium permanganate powder in the discharge bucket 4 will leak into the metering bucket 3 again for refilling, preparing for the next addition of potassium permanganate powder. The whole process does not require manual weighing, and the amount added each time is the same, saving addition time and improving the efficiency of manganese removal in the water plant.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
