Description
Technical Field
[0001] This invention belongs to the field of ammonia dilution technology, specifically relating to ammonia dilution tanks. Background Technology
[0002] Ammonia water is an alkaline solution formed by dissolving ammonia in water. It is widely used in chemical, agricultural, industrial cleaning and wastewater treatment fields. However, because it has strong corrosiveness, volatility and irritating odor when in high concentration, direct use can easily damage equipment or threaten the safety of operators. Therefore, it needs to be diluted to a safe concentration range before use. Usually, a special ammonia water dilution tank is used.
[0003] For example, CN 117380028 A discloses a device for diluting concentrated ammonia water for denitrification, which relates to the field of dilution device technology. It includes a mixing tank, a water spraying assembly, a heat preservation assembly, a stirring assembly, and a dilution process control system. The stirring assembly is installed inside the mixing tank. This invention uses a rotary motor to drive the stirring paddle to rotate, thereby achieving the stirring and dilution of ammonia water. However, it generally has the following drawbacks: the rotation direction is unidirectional, which easily leads to uneven mixing and low dilution efficiency. It is also easy to form density stratification or mixing dead zones, making it difficult for high-concentration ammonia water to quickly and fully contact the diluent, thus affecting the dilution effect and stability. Summary of the Invention
[0004] In view of this, the present invention provides an ammonia dilution tank, which can form a three-dimensional mixing field by the sprayed liquid flow, the vortex of the blades and the lateral stirring of the stirring plate, enhance turbulent diffusion, improve the stirring effect on ammonia and diluent, and achieve rapid and uniform mixing of ammonia and diluent. The multi-layer stirring effect of reverse rotation and the synergistic effect of liquid flow spraying significantly shorten the mixing time and improve the mixing uniformity and mixing efficiency of ammonia and diluent.
[0005] To solve the above-mentioned technical problems, the present invention provides an ammonia dilution tank, including a tank body and a stirring mechanism disposed thereon. The stirring mechanism is equipped with a transmission component. The stirring mechanism includes a rotating frame rotatably connected to the middle of the upper end of the tank body. Rotating rods are rotatably connected to the four corners of the rotating frame. The lower end of each rotating rod is provided with a ring-shaped, uniformly distributed stirring plate. A rotating rod is rotatably connected to the middle of the rotating frame. The lower end of the rotating rod is provided with a vertically uniformly distributed rotating disk. The opposite surfaces of the rotating disks are provided with ring-shaped, uniformly distributed blades. The tank body is equipped with a driving component for driving the rotating frame and rotating rod to rotate synchronously in opposite directions. The tank body is also equipped with a transmission component for driving the rotating rod to rotate. That is, a three-dimensional mixing field is formed by the sprayed liquid flow, the vortex of the blades, and the lateral stirring of the stirring plates, which enhances turbulent diffusion and improves the stirring effect on ammonia and diluent, realizing rapid and uniform mixing of ammonia and diluent. The multi-layer stirring effect of the reverse rotation and the synergistic effect of the liquid flow spray significantly shorten the mixing time and improve the mixing uniformity and mixing efficiency of ammonia and diluent.
[0006] The transmission assembly includes a transmission cavity set inside the rotating rod, and a diversion cavity is provided inside the rotating disk. Unidirectional nozzles are evenly distributed on the opposite surfaces of the rotating disk. The cavity wall of the transmission cavity is provided with annularly distributed connection holes near each diversion cavity. A rotating connector is externally rotatably connected to the upper end of the rotating rod near the opening of the transmission cavity, which serves to quickly transmit the diluent.
[0007] The drive assembly includes a bevel gear one located at the upper end of the rotating frame, a bevel gear two located at the upper end of the rotating rod, a U-shaped plate located at the upper end of the tank, an opening at the upper end of the U-shaped plate that matches the rotating rod, a support rod rotatably connected to one end of the U-shaped plate, and a bevel gear three located at the inner end of the support rod. Both bevel gear one and bevel gear two are meshed with bevel gear three, thus achieving the function of rapid drive.
[0008] The drive assembly also includes a motor located at the top of the tank. The output shaft of the motor is fixedly connected to one end of the support rod, thus providing a drive source for the support rod and its associated mechanisms.
[0009] The transmission assembly includes a bevel gear ring 1 disposed on the top wall of the tank, wherein the upper ends of the two oppositely distributed rotating rods are provided with bevel gears 4, which mesh with the bevel gear ring 1 to achieve rapid transmission.
[0010] The transmission assembly also includes a fixed ring located at the upper end of the inner cavity of the tank. The upper end of the fixed ring is provided with a bevel gear ring II, and the upper ends of the other two oppositely distributed rotating rods are each provided with a bevel gear V. The bevel gear V meshes with the bevel gear ring II, thus achieving the function of rapid transmission.
[0011] The small ends of bevel gear five and bevel gear four face opposite directions, thus serving as synchronous reverse transmission.
[0012] A rotating circular plate is rotatably connected inside the fixed ring. The rotating circular plate has a rotating hole that is rotatably connected to each rotating rod. The center of the rotating circular plate has a rotating hole that is rotatably connected to the rotating rod, which serves as a safety protection function.
[0013] The unidirectional nozzles and blades located on the same side of the rotating disk are spaced apart, which ensures that the diluted liquid at the spray point can be mixed quickly.
[0014] The beneficial effects of the above-described technical solution of the present invention are as follows:
[0015] 1. Add ammonia water to the tank and connect the external diluent supply pipe to the transmission component. Finally, the transmission component sprays the diluent into the outer tank. At this time, the drive component drives the rotating frame and rotating rod to rotate synchronously in opposite directions. When the rotating frame rotates, it drives the four rotating rods and stirring plates to rotate synchronously. At this time, driven by the transmission component, the rotating rods and stirring plates revolve around the revolution, causing the adjacent rotating rods and stirring plates to rotate synchronously in opposite directions, thereby greatly enhancing the stirring effect of ammonia water and diluent. At the same time, the rotating rods, rotating disks and their blades rotate to form a vertical shear flow. The sprayed liquid flow, the vortex of the blades and the lateral stirring of the stirring plates form a three-dimensional mixing field, which enhances turbulent diffusion and achieves rapid and uniform mixing of ammonia water and diluent. The multi-layer stirring effect of the reverse rotation and the synergistic effect of the liquid flow spray significantly shorten the mixing time and improve the mixing uniformity and mixing efficiency of ammonia water and diluent.
[0016] 2. Start the motor. Its output shaft drives the support rod and bevel gear three to rotate. Through the meshing of bevel gear one and bevel gear two, the rotating frame and the rotating rod rotate synchronously in opposite directions. When the rotating frame rotates, it drives the four rotating rods and the stirring plate to rotate synchronously. At this time, due to the meshing of bevel gear ring one and bevel gear four, bevel gear ring two and bevel gear five in the transmission assembly, as well as the design of bevel gear five and bevel gear four having opposite small end orientations, bevel gear four and bevel gear five rotate in opposite directions while revolving around each other. This causes the adjacent rotating rods and stirring plates to rotate synchronously in opposite directions, thereby greatly enhancing the stirring effect on ammonia water and diluent.
[0017] 3. The external diluent supply pipe is connected to the rotating connector. The diluent enters the transmission chamber of the rotating rod through the rotating connector, and is distributed to the distribution chamber of each rotating disk through the connection hole. Finally, it is sprayed outward by the one-way nozzle. The liquid flow sprayed by the one-way nozzle, the vortex of the blade and the lateral stirring of the stirring plate form a three-dimensional mixing field. Due to the spaced distribution design of the one-way nozzle and the blade, the liquid density stratification is broken and the turbulent diffusion is enhanced. Attached Figure Description

Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of the present invention. Figure 1-5 The technical solutions of the embodiments of the present invention will be clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.
[0025] This embodiment provides an ammonia dilution tank, such as Figure 1-5 As shown: It includes a tank body 100 and a stirring mechanism disposed thereon. The stirring mechanism is equipped with a transmission component. The stirring mechanism includes a rotating frame 200 rotatably connected to the middle of the upper end of the tank body 100. Rotating rods 201 are rotatably connected to the four corners of the rotating frame 200. The lower end of each rotating rod 201 is provided with a ring-shaped and uniformly distributed stirring plate 202. A rotating rod 203 is rotatably connected to the middle of the rotating frame 200. The lower end of the rotating rod 203 is provided with a vertically uniformly distributed rotating disk 204. The opposite surfaces of the rotating disk 204 are provided with ring-shaped and uniformly distributed blades 205. The tank body 100 is provided with a driving component for driving the rotating frame 200 and the rotating rod 203 to rotate synchronously in opposite directions. The tank body 100 is also provided with a transmission component for driving the rotating rod 201 to rotate.
[0026] First, ammonia water is added into the tank 100, and the external diluent supply pipe is connected to the transmission component. Finally, the transmission component sprays the diluent into the outer tank 100. At this time, the drive component drives the rotating frame 200 and the rotating rod 203 to rotate synchronously in opposite directions. When the rotating frame 200 rotates, it drives the four rotating rods 201 and the stirring plate 202 to rotate synchronously. At this time, driven by the transmission component, the rotating rods 201 and the stirring plate 202 revolve, causing the adjacent rotating rods 201 and the stirring plate 202 to rotate synchronously in opposite directions, thereby greatly enhancing the stirring effect of ammonia water and diluent. At the same time, the rotating rod 203, the rotating disk 204 and its blades 205 rotate, forming a vertical shear flow. The sprayed liquid flow, the vortex of the blades 205 and the lateral stirring of the stirring plate 202 form a three-dimensional mixing field, which strengthens turbulent diffusion and realizes rapid and uniform mixing of ammonia water and diluent. The multi-layer stirring effect of the reverse rotation and the synergistic effect of the liquid flow spray significantly shorten the mixing time and improve the mixing uniformity and mixing efficiency of ammonia water and diluent.
[0027] like Figure 1-5 As shown, the transmission assembly includes a transmission cavity 300 disposed within the rotating rod 203, a flow-dividing cavity 301 disposed within each of the rotating disks 204, and unidirectional nozzles 302 evenly distributed on the opposite surfaces of the rotating disks 204. The cavity wall of the transmission cavity 300 is provided with annularly evenly distributed connecting holes 303 near each flow-dividing cavity 301. A rotating connector 304 is rotatably connected to the upper end of the rotating rod 203 near the opening of the transmission cavity 300. The unidirectional nozzles 302 and blades 205 located on the same side of the rotating disks 204 are distributed at intervals.
[0028] The external diluent supply pipe is connected to the rotating connector 304. The diluent enters the transmission chamber 300 of the rotating rod 203 through the rotating connector 304, and is then diverted through the connection hole 303 to the diversion chamber 301 of each rotating disk 204. Finally, it is sprayed outward by the unidirectional nozzle 302 to achieve preliminary mixing and dilution.
[0029] like Figure 1-5 As shown, the drive assembly includes a bevel gear 400 disposed on the upper end of the rotating frame 200, a bevel gear 401 disposed on the upper end of the rotating rod 203, a U-shaped plate 402 disposed on the upper end of the tank body 100, an opening at the upper end of the U-shaped plate 402 adapted to the rotating rod 203, a support rod 403 rotatably connected to one end of the U-shaped plate 402, a bevel gear 404 disposed on the inner end of the support rod 403, and both the bevel gear 400 and the bevel gear 401 meshing with the bevel gear 404. The drive assembly also includes a motor 405 disposed on the upper end of the tank body 100, and the output shaft of the motor 405 is fixedly connected to one end of the support rod 403.
[0030] The motor 405 is started, and its output shaft drives the support rod 403 and the bevel gear 404 to rotate. Through the meshing of the bevel gear 400 and the bevel gear 401, the rotating frame 200 and the rotating rod 203 rotate synchronously in opposite directions. When the rotating frame 200 rotates, it drives the four rotating rods 201 and the stirring plate 202 to rotate synchronously. At the same time, the rotating rod 203, the rotating disk 204 and its blades 205 rotate, forming a vertical shear flow. The liquid flow sprayed from the one-way nozzle 302, the vortex of the blades 205 and the lateral stirring of the stirring plate 202 form a three-dimensional mixing field.
[0031] like Figure 2-5 As shown, the transmission assembly includes a bevel gear ring 500 disposed on the top wall of the tank 100. The upper ends of the two oppositely distributed rotating rods 201 are each provided with a bevel gear 501, which meshes with the bevel gear ring 500. The transmission assembly also includes a fixing ring 502 disposed on the upper end of the inner cavity of the tank 100. The upper end of the fixing ring 502 is provided with a bevel gear ring 503. The upper ends of the other two oppositely distributed rotating rods 201 are each provided with a bevel gear 504, which meshes with the bevel gear ring 503. The small ends of the bevel gear 504 and the bevel gear 401 face opposite directions.
[0032] Due to the opposite orientation of the small ends of bevel gear 504 and bevel gear 401, bevel gear 401 and bevel gear 504 drive the rotating rod 201 to rotate synchronously while revolving around each other, and the adjacent rotating rods 201 rotate in opposite directions, thereby greatly enhancing the stirring effect on ammonia water and diluent.
[0033] like Figure 2-5 As shown, a rotating circular plate 600 is rotatably connected inside the fixed ring 502. The rotating circular plate 600 is provided with a rotating hole that is rotatably connected to each rotating rod 201. The middle part of the rotating circular plate 600 is provided with a rotating hole that is rotatably connected to the rotating rod 203. The rotating circular plate 600 can prevent ammonia water from splashing into the area it protects when it is diluted, thus ensuring the long-term stable operation of each mechanism.
[0034] The working principle of the ammonia dilution tank provided by this invention is as follows: First, ammonia is added into the tank body 100, and the external dilution supply pipe is connected to the rotating connector 304. The dilution enters the transmission chamber 300 of the rotating rod 203 through the rotating connector 304, and is diverted to the diversion chambers 301 of each rotating disk 204 through the connection hole 303. Finally, it is sprayed outward by the one-way nozzle 302. At this time, the motor 405 is started, and its output shaft drives the support rod 403 and the bevel gear 3 404 to rotate. Through the meshing of bevel gear 1 400 and bevel gear 2 401, the rotating frame 200 and the rotating rod 203 rotate synchronously in opposite directions. When the rotating frame 200 rotates, it drives the four rotating rods 201 and the stirring plate 202 to rotate synchronously. At this time, the meshing of bevel gear ring 1 500 and bevel gear 4 501, bevel gear ring 2 503 and bevel gear 504 in the transmission assembly, and bevel gear 504 Due to the design influence of the opposite orientation of the small end of bevel gear 4 501, bevel gear 4 501 and bevel gear 504 rotate in opposite directions while revolving around each other. This causes the adjacent rotating rod 201 and stirring plate 202 to rotate synchronously in opposite directions, which greatly enhances the stirring effect on ammonia water and diluent. At the same time, the rotating rod 203, rotating disk 204 and its blades 205 rotate to form a vertical shear flow. The liquid flow sprayed from the unidirectional nozzle 302, the vortex of the blades 205 and the lateral stirring of the stirring plate 202 form a three-dimensional mixing field. Due to the spaced distribution design of the unidirectional nozzle 302 and the blades 205, the liquid density stratification is broken, the turbulent diffusion is enhanced, and the rapid and uniform mixing of ammonia water and diluent is achieved. The multi-layer stirring effect of the reverse rotation and the synergistic effect of the liquid flow spray significantly shorten the mixing time and improve the mixing uniformity and mixing efficiency of ammonia water and diluent.
[0035] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
[0036] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
