Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater treatment agent dosing device. Background Technology

[0002] In wastewater treatment, the accuracy and uniformity of chemical dosing have a significant impact on the treatment effect. Traditional wastewater treatment chemical dosing devices typically include a powder tank and a mixing tank. The powder is conveyed to the mixing tank via a threaded conveyor rod and mixed with water to form the wastewater treatment agent. However, this traditional dosing device has the following problems: First, due to the small size and light weight of the powder particles, they easily diffuse and fly during the conveying process, adhering to the inner wall of the mixing tank. This not only prevents the powder from effectively mixing with the water in the mixing tank, but also disrupts the originally weighed powder-to-water mixing ratio. For example, deviations can occur, thus affecting the effectiveness of wastewater treatment. In addition, the powder conveyed by the conveyor rod often enters the water in clumps, requiring a long time to mix evenly with the aqueous solution. This not only affects the effectiveness of the wastewater treatment agent but may also lead to excessively high or low local agent concentrations due to uneven mixing, further affecting the overall wastewater treatment effect. Furthermore, if water vapor in the mixing tank directly contacts the powder in the powder box when the screw conveyor rod is not rotating, it may cause the powder to clump, thus affecting the accuracy and stability of agent dosing. To solve the above problems, we propose a wastewater treatment agent dosing device. Summary of the Invention

[0003] In view of the problems of powder flying and adhering, uneven mixing and powder clumping in the above or existing technologies, the present invention is proposed.

[0004] Therefore, the object of the present invention is to provide a wastewater treatment agent dosing device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a wastewater treatment agent dosing device, comprising a reagent mixing mechanism, which includes a mixing tank, a powder storage component disposed on the mixing tank, and a feeding component disposed within the powder storage component; a spreading mechanism, which includes a disc disposed below the feeding component and arc-shaped blades arranged in a ring array on the disc; an atomizing mechanism, which includes an atomizing element disposed on the powder storage component; a water pump disposed at the top of the mixing tank; and a water pumping pipe disposed at the water pump inlet.

[0006] As a preferred embodiment of the wastewater treatment agent dosing device of the present invention, the powder storage component includes a support mounted on a mixing tank, a powder box welded to the support, and an inlet and a discharge pipe mounted on the powder box.

[0007] As a preferred embodiment of the wastewater treatment agent dosing device of the present invention, the feeding assembly includes a drive motor disposed at the top of the powder box, a drive rod fixedly connected to the output shaft of the drive motor and located inside the powder box, and a spiral blade disposed on the drive rod, wherein the maximum diameter of the spiral blade matches the inner diameter of the feeding pipe.

[0008] In a preferred embodiment of the wastewater treatment agent dosing device of the present invention, a telescopic column is welded at the center of the top of the disc, and a stop block is welded at the top of the telescopic column. A compression spring is sleeved on the telescopic column, and one end of the compression spring abuts against the stop block.

[0009] As a preferred embodiment of the wastewater treatment agent dosing device of the present invention, the lower end of the drive rod is provided with a movable cavity, and the telescopic column extends through the bottom end of the drive rod into the movable cavity. The compression spring and the stop block are both disposed in the movable cavity, and the end of the compression spring away from the stop block abuts against the bottom end of the movable cavity.

[0010] In a preferred embodiment of the wastewater treatment agent dosing device of the present invention, the bottom end of the discharge pipe is provided with an avoidance chamfer, the top end of the disc is provided with a spreading chamfer, and the spreading chamfer and the avoidance chamfer are matched.

[0011] In a preferred embodiment of the wastewater treatment agent dosing device of the present invention, the bottom end of the disc is provided with a pull rope in a circular array, and the end of the pull rope away from the disc is fixedly connected to a resistance element.

[0012] As a preferred embodiment of the wastewater treatment agent dosing device of the present invention, the atomizing element includes an annular pipe fixedly installed on the outer wall of the feed pipe, an atomizing nozzle arranged in an annular array on the annular pipe, and a water supply pipe for connecting the annular pipe and the water pump outlet, wherein the water pumping pipe extends into the lower end of the mixing tank.

[0013] As a preferred embodiment of the wastewater treatment agent dosing device of the present invention, wherein: an inlet flange pipe is provided at the upper end of one side of the mixing tank, and a dispensing flange pipe is provided at the lower end of one side of the mixing tank.

[0014] In a preferred embodiment of the wastewater treatment agent dosing device of the present invention, a control box is fixedly installed on one side of the mixing tank, and the control box is electrically connected to the drive motor and the water pump through wires.

[0015] The beneficial effects of the wastewater treatment agent dosing device of the present invention are as follows: In the present invention, the disc, under the action of the compression spring and the sealing match of the feed pipe, avoids the situation where water vapor in the mixing tank causes the powder in the powder box to clump. When the powder is fed, the downward pressure of the powder and the downward pull of the water generated by the resistance element as the disc rotates cause the disc and the feed pipe to separate, so that the powder on the disc can be evenly spread to the water surface by the centrifugal force of rotation. The powder spread to the water surface and the water flow driven by the resistance element are quickly mixed.

[0016] Meanwhile, as the powder is spread by the centrifugal force of the rotating disc, the water pump draws water from the mixing tank and sprays it out through the atomizing element to initially wet and reduce dust on the spread powder. This prevents the powder from flying and adhering to the inner wall of the mixing tank, which would prevent the powder from effectively mixing with the water in the mixing tank and thus affecting the wastewater treatment effect.

Detailed Implementation

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one 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 or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1, referring to Figures 1 to 2 This is the first embodiment of the present invention. This embodiment provides a wastewater treatment agent dosing device, which solves the problems of powder flying and adhering when the powder tank 102b is fed into the mixing tank 101, and the difficulty in uniformly mixing with the aqueous solution. It includes an agent mixing mechanism 100, which includes a mixing tank 101, a powder storage component 102 disposed on the mixing tank 101, and a dispensing component 103 disposed inside the powder storage component 102. The powder storage component 102 is fixedly installed on the top of the mixing tank 101, and the dispensing component 103 is disposed inside the powder storage component 102 and extends into the mixing tank 101. According to the requirements, an appropriate amount of powder and aqueous solution are prepared, the powder is poured into the powder storage component 102, the aqueous solution is added to the mixing tank 101, and the dispensing component 103 is activated to transport the powder into the mixing tank 101 to mix with the aqueous solution to form a wastewater treatment agent.

[0028] The spreading mechanism 200 includes a disc 201 disposed below the feeding component 103, and an arc-shaped blade 202 arranged in a ring array on the disc 201. The disc 201 is disposed below the feeding component 103 and rotates with the drive of the feeding component 103. So when the feeding component 103 conveys the powder downward, the powder falls onto the disc 201, and then the powder is spread to the surrounding area by the centrifugal force of the disc 201 and the arc-shaped blade 202 in the ring array.

[0029] It should be noted that without the curved blades 202, the powder is relatively light and the friction force acting on the disc 201 is small. Therefore, the powder falling on the disc 201 may not be thrown out, or the amount thrown out may not be uniform. With the curved blades 202, if the powder is not thrown out and spread immediately as the disc 201 rotates, it will come into contact with the side wall of the curved blades 202 and then be thrown out by the curved surface of the curved blades 202 to achieve uniform spreading.

[0030] The atomizing mechanism 300 includes an atomizing element 301 disposed on the powder storage assembly 102, a water pump 302 disposed at the top of the mixing box 101, and a water pumping pipe 303 disposed at the water inlet of the water pump 302.

[0031] The powder storage assembly 102 includes a support 102a disposed on a mixing box 101, a powder box 102b welded to the support 102a, and a feed inlet 102c and a discharge pipe 102d disposed on the powder box 102b.

[0032] In this embodiment, the powder box 102b is welded to the top of the mixing box 101 via the bracket 102a. The lower end of the powder box 102b is tapered to facilitate the falling of the powder. The feed pipe 102d is a cylindrical pipe that is matched and welded to the bottom of the powder box 102b. The feed pipe 102d passes through the top of the mixing box 101 and extends to the upper part of the interior of the mixing box 101. The atomizing element 301 is fixedly installed on the lower end of the circumferential side wall of the feed pipe 102d to spread the powder as the disc 201 rotates. When the powder is sprayed out from the separation gap between the feed pipe 102d and the disc 201, it is diffused and atomized. At this time, the water pump 302 is started, and the water pump 302 pumps the aqueous solution in the mixing box 101 to the atomizing element 301 through the water pumping pipe 303. The atomizing element 301 sprays out the powder to wet the spread powder, so as to avoid the powder flying and sticking to the side wall of the mixing box 101, thereby improving the accuracy of the mixing ratio of powder and aqueous solution.

[0033] The feeding assembly 103 includes a drive motor 103a disposed at the top of the powder box 102b, a drive rod 103b fixedly connected to the output shaft of the drive motor 103a and located inside the powder box 102b, and a spiral blade 103c disposed on the drive rod 103b. The maximum diameter of the spiral blade 103c matches the inner diameter of the feeding pipe 102d.

[0034] In this embodiment, the drive motor 103a is fixedly installed on the top of the powder box 102b, the drive rod 103b is disposed inside the powder box 102b and extends into the feed pipe 102d, the spiral blade 103c is disposed at the lower end of the circumferential side wall of the drive rod 103b, and one end of the drive rod 103b is still retained below the spiral blade 103c, and the drive rod 103b and one end of the arc-shaped blade 202 of the annular array are combined to form a circular plug-in match.

[0035] Furthermore, the feeding pipe 102d and the spiral blade 103c are matched. This design ensures that when the drive motor 103a drives the drive rod 103b to rotate and drives the spiral blade 103c to transport the powder, the powder will not spread outward. This allows the powder to be spread only through the gap between the disc 201 and the feeding pipe 102d, avoiding the situation where the powder spreads and sticks to the inner wall of the mixing box 101.

[0036] A water inlet flange pipe 101a is provided on the upper side of one side of the mixing tank 101, and a dispensing flange pipe 101b is provided on the lower side of one side of the mixing tank 101.

[0037] In this embodiment, the inlet flange pipe 101a is connected to the inlet pipe and is used to add aqueous solution to the mixing tank 101. The dispensing flange pipe 101b is connected to the pump 302 for dispensing treatment agents. The pump 302 dispenses the mixed wastewater treatment agents into the wastewater through the dispensing flange pipe 101b, thereby completing the wastewater purification treatment.

[0038] Example 2, refer to Figures 1 to 5 This is the second embodiment of the present invention. Unlike the previous embodiment, a telescopic column 203 is welded to the center of the top of the disc 201, and a stop block 204 is welded to the top of the telescopic column 203. A compression spring 205 is sleeved on the telescopic column 203, and one end of the compression spring 205 abuts against the stop block 204.

[0039] The lower end of the drive rod 103b has a movable cavity 103b-1, and the telescopic column 203 extends through the bottom end of the drive rod 103b into the movable cavity 103b-1. The compression spring 205 and the stop block 204 are both located in the movable cavity 103b-1, and the end of the compression spring 205 away from the stop block 204 abuts against the bottom end of the movable cavity 103b-1.

[0040] In this embodiment, the drive rod 103b, which is connected to the circular matching drive rod 103b formed by the arc-shaped blades 202 of the annular array, has an active cavity 103b-1 inside. The active cavity 103b-1 is a square cavity, and the stop block 204 is a square plate. The stop block 204 and the active cavity 103b-1 move up and down to match. The compression spring 205 is set in the active cavity 103b-1. The elastic force of the compression spring 205 pushes the stop block 204 upward and presses it against the bottom of the active cavity 103b-1, so that the telescopic column 203 enters the active cavity 103b-1, thereby making the disc 201 fit against the bottom of the feed pipe 102d, realizing the sealing and isolation between the powder box 102b and the mixing box 101 at the upper end of the feed pipe 102d, and preventing the moisture in the mixing box 101 from causing the powder in the powder box 102b to clump.

[0041] The bottom of the feeding pipe 102d is provided with a clearance chamfer 102d-1, and the top of the disc 201 is provided with a spreading chamfer 201a. The spreading chamfer 201a and the clearance chamfer 102d-1 are matched. The spreading chamfer 201a on the disc 201 provides a downward force when the powder is spread, making it easier to spread. Furthermore, when the disc 201 and the feeding pipe 102d are sealed together, the spreading chamfer 201a and the clearance chamfer 102d-1 provide a seal. -1 matching provides a better seal than horizontal bonding even when the fit is not tight enough. This is because with chamfered bonding, moisture entering the powder box 102b from the mixing box 101 first enters the gap of the chamfer horizontally, and then collides with the chamfered corner 201a, creating resistance and slowing down the entry of moisture. In contrast, with horizontal bonding, when gaps occur, moisture directly enters the discharge pipe 102d horizontally and moistens the powder in the powder box 102b, making the powder more prone to clumping.

[0042] The bottom of the disc 201 is provided with a ring array of pull ropes 206, and the end of the pull ropes 206 away from the disc 201 is fixedly connected to a resistance element 207.

[0043] In this embodiment, the pull rope 206 can be replaced. The pull rope 206 of appropriate length can be replaced according to the different volumes of aqueous solution to ensure that the resistance component 207 fixedly installed on the pull rope 206 can be inside the aqueous solution and located in the upper part. The resistance component 207 consists of a cylindrical rod and a semi-circular cover, and the semi-circular cover has multiple water passage holes. The axial direction of the cylindrical rod and the axial direction of the semi-circular cover intersect each other, that is, the vector direction of the tangential surface of the semi-circular cover and the axial direction of the cylindrical rod are set at an angle.

[0044] The rest of the structure is the same as in Example 1.

[0045] When the drive motor 103a drives the drive rod 103b to rotate and feed the material, the spiral blades 103c convey the powder in the powder box 102b downwards. When the powder falls from the spiral blades 103c onto the disc 201, it is separated by the arc-shaped blades 202 on the disc 201. The rotation of the drive rod 103b also drives the disc 201 to rotate. The rotation of the disc 201 drives the resistance element 207 of the annular array to rotate through the pull rope 206. When the resistance element 207 rotates with the disc 201, the pull rope 206 is inclined due to the water resistance of the resistance element 207. When the pull rope 206 pulls the resistance element 207, it is connected to the cylinder. The rod and the pull rope 206 are coaxial. At this time, the cross-section of the upper semi-circular cover of the resistance component 207 is set vertically. When the resistance component 207 rotates with the disc 201, it pushes the water flow through the concave arc surface of the semi-circular cover, causing the water flow to be stirred. At this time, the resistance of the water flow to the resistance component 207 will be partially converted into a downward pulling force, thereby pulling the disc 201 downward, so that a gap is created between the disc 201 and the feed pipe 102d, so that the powder on the disc 201 can be spread. The spread powder mixes with the water flow stirred by the resistance component 207, dissolves quickly, and avoids the situation where the powder clumps and is difficult to dissolve.

[0046] It should be noted that the drag component 207, the disc 201 and the arc blade 202 are all made of lightweight materials. However, the lightweight material of the drag component 207 needs to ensure that it can sink in water. The water passage hole on the drag component 207 is also designed to prevent the drag component 207 from floating.

[0047] Furthermore, when the downward force generated by the resistance component 207 through the water flow resistance drives the disc 201 to move downward and the feed pipe 102d to create the maximum gap, the arc-shaped blade 202 still does not detach from the lower end of the drive rod 103b. This allows the compression spring 205 to push the stop block 204 upward to reset the disc 201 and seal the feed pipe 102d, enabling the disc 201 to move upward smoothly.

[0048] Example 3, referring to Figures 1 to 5 This is the third embodiment of the present invention. Unlike the previous embodiment, it includes an atomizing component 301, which includes an annular pipe 301a fixedly installed on the outer wall of the feed pipe 102d, an atomizing nozzle 301b arranged in an annular array on the annular pipe 301a, and a water supply pipe 301c for connecting the annular pipe 301a and the outlet of the water pump 302. The water pumping pipe 303 extends into the lower end of the mixing box 101.

[0049] The annular tube 301a is fixedly installed at the lower end of the circumferential side wall of the feed tube 102d, and multiple atomizing nozzles 301b are arranged in an annular array. The nozzles of the atomizing nozzles 301b are all tilted downwards at a 45-degree angle, so that the water vapor sprayed out by atomization can quickly wet the powder and prevent the powder from flying away.

[0050] A control box 400 is fixedly installed on one side of the mixing tank 101, and the control box 400 is electrically connected to the drive motor 103a and the water pump 302 via wires.

[0051] The control box 400 is equipped with multiple control buttons, with the start buttons for the drive motor 103a and the water pump 302 each corresponding to one control button.

[0052] The rest of the structure is the same as in Example 2.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
