Description

Technical Field

[0001] This utility model relates to the technical field of jet mixing devices, specifically, to a jet mixing device. Background Technology

[0002] In many fields such as industrial production, environmental protection, and municipal engineering, the precise and efficient mixing of liquid agents with the main body is crucial. Traditional dosing and mixing methods have numerous drawbacks. First, the agent addition process often relies on manual dispensing by breaking open bags, which is inefficient, labor-intensive, and involves frequent contact with chemicals, endangering the health and safety of operators. Furthermore, inaccurate dosages due to operational differences can affect the stability of the mixing effect.

[0003] Secondly, in the mixing process, the common method is to directly pour the agent into the main fluid container or pipeline. The two rely solely on natural diffusion to fuse, which is time-consuming and prone to local uneven concentration. Agent agglomeration and precipitation problems occur frequently. In wastewater treatment with flocculants and in the batching of chemical production materials, this leads to incomplete reaction and large fluctuations in product quality.

[0004] Furthermore, traditional pipeline mixing devices have a simple structure and lack scientific design to guide fluid flow. They cannot create strong turbulence and negative pressure environments, making it difficult for the agent to be fully entrained and broken up by the high-speed main fluid in a short time and a small space, and to be evenly dispersed throughout the entire fluid system. Utility Model Content

[0005] This invention proposes a jet mixing device that solves the problem of uneven drug mixing after mixing and adding drugs in related technologies.

[0006] The technical solution of this utility model is as follows:

[0007] A jet mixing device, comprising:

[0008] Mixing tube, the mixing tube having a mixing chamber,

[0009] The dosing tube leads to the mixing chamber.

[0010] A jet tube leads to the mixing chamber, and the dosing tube is arranged perpendicular to the axis of the jet tube.

[0011] A bag-breaking device is disposed on one side of the dosing tube, and the bag-breaking device has a dosing chamber that leads to the dosing tube.

[0012] As a further technical solution, the jet tube has a flow tube section and a jet section, the flow tube section leads to the jet section, the inner wall of the jet section has a spiral guide section, and the jet section leads to the mixing chamber.

[0013] As a further technical solution, the spiral guide portion is arranged in several circles.

[0014] As a further technical solution, the end of the bag-breaking component has a bag-breaking head, which is used to puncture the packaging of the medicine to be added. The bag-breaking head has a leakage port, which is located on the side wall of the bag-breaking head and leads to the medicine adding tube.

[0015] As a further technical solution, the bag-breaking component also has a feeding port, which is located on the side wall at the connection between the bag-breaking component and the dosing tube. Both the feeding port and the leakage port lead to the dosing tube.

[0016] As a further technical solution, the mixing tube has a spherical part and a conical part, the spherical part has the mixing cavity, the conical part has a conical channel, and the mixing cavity leads to the conical channel.

[0017] As a further technical solution, the bag-breaking component includes:

[0018] The main body includes the bag-breaking head, which has a dosing chamber. Both the feeding port and the leakage port lead to the dosing chamber, which in turn leads to the dosing pipe.

[0019] A sliding member is slidably disposed within the dosing chamber and located on one side of the feed inlet and the discharge outlet. The sliding member is configured to block the feed inlet when slidable, while simultaneously releasing the blockage of the discharge outlet.

[0020] An elastic element, one end of which acts on the inner wall of the dosing chamber and the other end of which acts on the sliding element, provides the sliding element with a force to block the leakage port.

[0021] As a further technical solution, the sliding member has a protruding end that extends out of the discharge port and is used to abut against the packaging.

[0022] The working principle and beneficial effects of this utility model are as follows:

[0023] In this invention, a mixing chamber is provided inside the mixing tube. The mixing chamber is cylindrical or near-cylindrical in shape to ensure smooth fluid flow within the chamber, laying a solid foundation for uniform mixing of the agent and the fluid. One end of the dosing pipe leads to the mixing chamber and is used to deliver the agent to the mixing area. It is perpendicular to the axis of the jet pipe, allowing the high-speed fluid introduced by the jet pipe to form a transverse scouring flow pattern within the mixing chamber. When the agent is injected from the dosing pipe, it is rapidly broken up and entrained by this flow pattern, integrating into the fluid. The diameter of the dosing pipe is reasonably determined based on the common agent flow rate requirements. The jet pipe also leads to the mixing chamber and is responsible for introducing the main fluid with a certain flow velocity and pressure. By connecting an external high-pressure pump or power equipment, the main fluid can be driven into the mixing chamber in the form of a high-speed jet, creating a strong turbulent environment and enhancing the mixing effect. The end of the jet pipe is often designed to be constricted, similar to a nozzle, to increase the fluid ejection velocity and impact force, which helps to break the laminar flow state of the fluid and accelerate the dispersion of the agent. The bag-breaking device is located on one side of the dosing pipe and has a dosing chamber inside, which is connected to the dosing pipe. The bag-breaking device uses a mechanical bag-breaking principle. When the bagged medicine is fed into the dosing device, the packaging bag is torn by the mechanical parts, and the medicine flows into the dosing pipe, realizing automatic bag breaking and dosing, avoiding the drawbacks of manual bag breaking.

[0024] Based on the Venturi principle, a high-speed flowing liquid is forcefully injected into the mixing chamber through a jet tube. A negative pressure environment is cleverly created within the mixing chamber, precisely and continuously drawing the agent released from the bag-breaking device on one side of the dosing tube into the mixing chamber. Under the suction of negative pressure, the agent is entrained and torn apart by the high-speed fluid, instantly breaking up any potential agglomeration. This ensures that the agent fully contacts and mixes with the slurry from the very beginning of its entry into the mixing chamber. Attached Figure Description

Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] Reference Figures 1-3 The first embodiment of this utility model proposes a jet mixing device, including a mixing pipe 1, the mixing pipe 1 having a mixing cavity 101, a dosing pipe 2 leading to the mixing cavity 101, a jet pipe 3 leading to the mixing cavity 101, the dosing pipe 2 and the jet pipe 3 being arranged perpendicularly to each other, a bag breaking component 4 being arranged on one side of the dosing pipe 2, the bag breaking component 4 having a dosing cavity 401 leading to the dosing pipe 2.

[0035] In this embodiment, the mixing pipe 1 has a mixing chamber 101 inside. The mixing chamber 101 is cylindrical or near-cylindrical in shape to ensure smooth fluid flow within the chamber, laying a solid foundation for uniform mixing of the agent and the fluid. One end of the dosing pipe 2 leads to the mixing chamber 101 and is used to deliver the agent to the mixing area. It is perpendicular to the axis of the jet pipe 3, which allows the high-speed fluid introduced by the jet pipe 3 to form a transverse scouring flow pattern within the mixing chamber 101. When the agent is injected from the dosing pipe 2, it is rapidly broken up and entrained by this flow pattern and integrated into the fluid. The diameter of the dosing pipe 2 is reasonably determined according to the common agent flow requirements. The jet pipe 3 also leads to the mixing chamber 101 and is responsible for introducing the main fluid with a certain flow velocity and pressure. By connecting an external high-pressure pump or power equipment, the main fluid can be driven into the mixing chamber 101 in the form of a high-speed jet, creating a strong turbulent environment and enhancing the mixing effect. The jet tube 3 is often designed with a constricted end, similar to a nozzle, to increase the fluid ejection velocity and impact force, which helps to break the laminar flow state and accelerate the dispersion of the agent. The bag-breaking component 4 is located on one side of the dosing tube 2 and has a dosing chamber 401 inside, which is connected to the dosing tube 2. The bag-breaking component 4 adopts a mechanical bag-breaking principle. When the bagged agent is sent into the dosing device, the packaging bag is torn under the action of the mechanical parts, and the agent enters the dosing tube 2, realizing automatic bag-breaking and dosing, avoiding the drawbacks of manual bag breaking.

[0036] Based on the Venturi principle, high-speed flowing liquid is forcefully injected into the mixing chamber 101 through the jet pipe 3, cleverly creating a negative pressure environment within the mixing chamber. This precisely and continuously draws the agent released from the bag-breaking component 4 on one side of the dosing pipe 2 into the mixing chamber 101. Under the suction of negative pressure, the agent is entrained and torn apart by the high-speed fluid, instantly breaking up any potential agglomeration. This ensures that the agent fully contacts and mixes with the slurry from the very beginning of its entry into the mixing chamber.

[0037] Furthermore, the jet tube 3 has a flow tube section 301 and a jet section 302, the flow tube section 301 leads to the jet section 302, and the inner wall of the jet section 302 has a spiral guide section 303.

[0038] In this embodiment, the inner wall of the jet section 302 is equipped with a spiral guide section 303. When high-speed liquid flows into the jet section 302 from the flow tube section 301, the spiral guide section 303 applies a "rotational torque" to the fluid, causing the fluid to be ejected at high speed along a spiral trajectory. This powerfully agitates the static or slowly flowing liquid to be mixed, giving the subsequent mixing of the agent and the fluid more abundant initial kinetic energy and accelerating the mixing process. The spiral guide section 303 guides the fluid to be ejected in a spiral path, allowing the fluid to achieve all-round and multi-angle diffusion within the mixing chamber 101. Unlike traditional straight-tube jets, which are prone to localized concentrated impacts and uneven agent dispersion, spiral jets can uniformly cover a wider area of ​​the mixing chamber.

[0039] Furthermore, the spiral guide 303 is arranged in several circles.

[0040] In this embodiment, the spiral guide 303 is arranged in several circles on the inner wall of the jet section 302. When the liquid flows through the jet section 302 at high speed, the spiral guide 303 arranged in each circle exerts force at the same time, giving the fluid spiral rotation power from different radial positions, causing the fluid to form multiple tightly intertwined and co-rotating jet bundles.

[0041] Furthermore, the end of the bag-breaking component 4 has a bag-breaking head 402, which is used to puncture the packaging of the medicine to be added. The bag-breaking head 402 has a leakage port 403, which is located on the side wall of the bag-breaking head 402.

[0042] In this embodiment, the bag-piercing head 402 integrates puncture and flow control functions. With its sharp shape, it can pierce the packaging material with minimal resistance upon contact with the drug packaging, as cleanly as a sharp blade cutting through paper. It can efficiently penetrate paper, plastic, or thin composite material packaging bags.

[0043] The placement of the discharge port 403 on the side wall of the bag-breaking head 402 is ingenious. When the drug packaging is punctured, the drug flows out from the discharge port 403 on the side wall under the synergistic effect of gravity and negative pressure suction in the mixing chamber. Compared to the bottom opening design, which is prone to clogging by packaging bag fragments, the side wall opening effectively avoids this problem. In the scenario of adding powdered catalysts, traditional bottom discharge often encounters blockages and interrupts operations. The side wall discharge port 403 of this device ensures that the drug flows continuously and smoothly into the mixing chamber 101, and the mixing process is uninterrupted. The entire bag-breaking process is completed within the closed space of the bag-breaking component 4. At the moment the bag-breaking head 402 punctures the packaging, the drug dust is firmly locked in due to the outer shell. The bag head 402 and the discharge port 403 work closely together to strictly control the drug flow direction and prevent drug leakage to the surrounding area of ​​the equipment.

[0044] Furthermore, the bag-breaking component 4 also has a feeding port 404, which is located on the side wall at the connection between the bag-breaking component 4 and the dosing pipe 2. Both the feeding port 404 and the leakage port 403 lead to the dosing pipe 2.

[0045] In this embodiment, the feeding port 404 added to the bag-breaking component 4 is located on the side wall where it connects to the dosing pipe 2, and together with the leakage port 403, it leads to the dosing pipe 2, thus forming a dual-feeding system. In actual operation, this design effectively avoids the blockage and flow fluctuation problems that may occur due to a single-diameter feeding port.

[0046] Furthermore, the mixing tube 1 has a spherical portion 102 and a conical portion 103. The spherical portion 102 has a mixing cavity 101, and the conical portion 103 has a conical channel 104. The mixing cavity 101 leads to the conical channel 104.

[0047] In this embodiment, the spherical portion 102 of the mixing pipe 1 serves as the core mixing region. Its unique geometric shape provides a solid foundation for the mixing of fluid and reagent. When the jet pipe 3 injects fluid at high speed and the dosing pipe 2 simultaneously introduces reagent into the mixing chamber 101, the spherical cavity promotes the rapid formation of a multi-dimensional swirling flow, preventing obstruction of liquid flow.

[0048] The conical channel 104 of the conical portion 103 is seamlessly connected to the spherical portion 102, performing a sophisticated function of guiding flow and concentrating energy. The mixed fluid-pharmaceutical mixture flows from the mixing chamber 101 into the conical channel 104, and the cross-sectional area of ​​the channel gradually expands.

[0049] The spherical part 102 naturally possesses good mechanical structural stability, similar to the principle of an "arch," which can evenly distribute the internal fluid pressure and withstand the impact of high-speed jets and fluid turbulence pressure fluctuations. The conical part 103 closely extends from the spherical part 102, and the two are integrally formed or firmly welded together, enhancing the overall structural strength.

[0050] The fluid transitions from the spherical section 102 to the conical section 103. This gradual channel design effectively buffers sudden changes in flow velocity and pressure, reducing the direct "scouring and abrasion" force of the fluid on the pipe wall. Compared to ordinary straight-tube mixed flow pipes, the wear on the inner wall of this mixed flow pipe is more uniform and less severe under long-term operation. Especially in high-flow-rate, high-frequency operation scenarios, the wear rate is reduced by approximately 30% - 40%, reducing maintenance costs and ensuring long-term efficient operation of the equipment, continuously outputting high-quality mixed slurry.

[0051] Furthermore, the bag-breaking component 4 includes a main body 405, which has a bag-breaking head 402. The bag-breaking head 402 has a dosing chamber 401. The feeding port 404 and the leakage port 403 both lead to the dosing chamber 401, which leads to the dosing pipe 2. The sliding component 408 is slidably disposed in the dosing chamber 401 and is located on one side of the feeding port 404 and the leakage port 403. The sliding component 408 is configured to block the feeding port 404 after sliding, while simultaneously releasing the blocking of the leakage port 403. One end of the elastic component 409 acts on the inner wall of the dosing chamber 401, and the other end acts on the sliding component 408, providing the sliding component 408 with the force to block the leakage port 403.

[0052] In this embodiment, the sliding member 408 and the elastic member 409 in the bag-breaking component 4 work together to provide precise control over the drug feeding. When the drug is poured into the container, it can enter the dosing tube 2 through the feeding port 404, preventing the leakage port 402 from affecting the negative pressure adsorption efficiency. Similarly, when using bagged drugs, the feeding port 404 is blocked by the sliding member 408 to prevent it from affecting the negative pressure at the leakage port 403, thus ensuring the dosing effect.

[0053] Furthermore, the slider 408 has an extension end 410 that extends out of the discharge port 403 for contacting the packaging.

[0054] In this embodiment, the protruding end 410 of the slider 408 extends out of the discharge port 403 and abuts against the packaging of the medicine to be added. This design achieves precise bag-breaking positioning and medicine diversion functions. When the bagged medicine is placed in the appropriate position for addition, the protruding end 410 first contacts the packaging. The protruding end 410 can accurately guide the slider 408 to slide and block the discharge port 404, while simultaneously removing the blockage of the discharge port 403, reducing manual operation and improving efficiency.
