Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically a mixer with a dripping device. Background Technology

[0002] In industries such as chemical, pharmaceutical, and food processing, mixing equipment is an indispensable processing device used to achieve mixing, homogenization, and reaction of materials. Especially when processing high-viscosity chemical materials, higher demands are placed on the mixing efficiency and homogenization effect of the mixing equipment.

[0003] In actual production, it is often necessary to slowly and in small amounts add one or more liquid additives or reaction liquids while stirring the main material. Traditional addition methods mostly involve manually pouring the liquid directly into the mixing tank or relying on gravity to flow through a simple pipe. These methods have the following significant drawbacks: (1) Liquid materials tend to flow or drip along the inner wall of the mixing tank: Due to the adhesiveness of high-viscosity materials, the liquid flowing down the wall will be adhered to the material on the tank wall and will be difficult to be quickly carried into the main stirring area in the center of the tank, resulting in excessively high local concentration, uneven mixing, and affecting product quality and reaction efficiency; (2) The addition speed and amount are difficult to control precisely: Manual pouring or simple valve control cannot achieve stable and slow dripping, which can easily cause excessive instantaneous feeding. For some reaction processes that are sensitive to the feeding rate (such as polymerization reaction), it can cause side reactions or problems such as excessively wide molecular weight distribution of the product; (3) Single function and poor adaptability: Most conventional mixers do not integrate a dedicated dripping device, which requires additional configuration and installation, occupies space and is inconvenient to operate. Meanwhile, existing equipment lacks effective solutions for operating conditions that require the addition of multiple liquids or the addition at multiple points. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a mixer with a dripping device that can be integrated into a mixing equipment, enabling slow and precise dripping and effectively preventing liquid from flowing along the wall, thereby solving the problem of liquid addition during the mixing of high-viscosity materials.

[0005] The technical solution adopted by this utility model is as follows: a mixer with a dripping device, including a mixer body and a mixing tank that cooperates with the mixer body, and also including a dripping device;

[0006] The dripping device includes a tank for storing the dripping liquid, and the tank wall of the mixing tank is provided with a liquid injection pipe that communicates with the inside of the mixing tank, the inner end of the liquid injection pipe protruding from the inner wall of the mixing tank.

[0007] The liquid outlet of the material tank is connected to the liquid injection pipe through a liquid delivery pipe. The liquid outlet of the material tank is equipped with a switch valve for controlling the on / off state, and the liquid delivery pipe is equipped with a throttle valve for controlling the flow rate.

[0008] Furthermore, the inner end of the injection tube protrudes from the inner wall of the mixing tank by a length of 5mm to 20mm.

[0009] Furthermore, the switching valve is a ball valve, butterfly valve, or gate valve.

[0010] Furthermore, the material tank is equipped with a level gauge.

[0011] Furthermore, the injection tube and the infusion tube are detachably connected.

[0012] Furthermore, the dripping device also includes a support frame fixedly connected to the mixer body, and the material bucket is installed on the mixer body through the support frame.

[0013] Furthermore, the mixing tank has two injection pipes on its wall, and the two injection pipes are arranged at intervals along the circumference of the mixing tank; the dripping device is correspondingly provided with two material tanks, and each material tank is connected to one injection pipe through an independent set of infusion pipes, a switch valve and a throttle valve.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) This utility model integrates the dripping device as an integral part of the mixer, avoiding the hassle of additional installation, saving equipment space, and allowing users to directly use the dripping function without complicated modifications, which greatly improves the convenience and ease of use of the equipment.

[0016] (2) Through the coordinated action of the switch valve set at the liquid outlet end of the material tank and the throttle valve on the liquid delivery pipeline, the operator can first use the switch valve to open or close the material flow, and then use the throttle valve to precisely control the dripping speed. This two-stage control method achieves precise matching of the process requirements of small amount and slow addition, and is particularly suitable for reaction processes that are sensitive to the feeding rate.

[0017] (3) In this utility model, the inner end of the injection pipe protrudes from the inner wall of the mixing tank, so that the liquid flowing out from the injection pipe can directly detach from the tank wall and drip into the material inside the mixing tank, avoiding the problem that the added liquid material flows down the tank wall and cannot participate in effective mixing, so that the added liquid can be quickly captured and dispersed by the main stirring flow, greatly improving the mixing uniformity and efficiency.

[0018] (4) By setting up two or more spaced injection pipes and corresponding independent material tank systems, it is possible to meet the needs of adding multiple different liquid materials at the same time or in sequence, or adding the same material at different points in the mixing tank. This can further avoid excessive local concentration and accelerate the mixing process, and is especially suitable for large mixing equipment or occasions where the mixing uniformity is extremely high.

[0022] To facilitate understanding of this utility model, it will be described more comprehensively and in detail below with reference to the accompanying drawings and preferred embodiments. However, the scope of protection of this utility model is not limited to the following specific embodiments.

[0023] like Figure 1 and Figure 2 As shown, this utility model provides a mixer with a dripping device. This mixer is mainly used for the mixing process of high-viscosity chemical materials and can achieve slow and precise addition of liquid materials during the mixing process.

[0024] The mixer includes a mixer body 1, a mixing tank 2, and a dripping device 3. The mixer body 1 is a conventional structure in the art, mainly including a drive motor and a stirring shaft (not shown in detail in the figure). The stirring shaft extends into the mixing tank 2 and is equipped with stirring blades suitable for stirring high-viscosity materials.

[0025] The dripping device 3 includes a support frame 32, a material tank 31, a switch valve 33, a throttle valve 34, a delivery pipe 35, and an injection pipe 36.

[0026] The support frame 32 is fixedly connected to the mixer body 1, and the material tank 31 is stably installed above the mixer body 1 via the support frame 32, facilitating dripping by gravity. The material tank 31 is used to store the liquid material to be dripped, and it is preferably equipped with a level gauge (not shown in the figure) to facilitate observation of the remaining amount of liquid in the tank.

[0027] A switch valve 33 is installed at the liquid outlet of the material tank 31. This switch valve 33 is used to control the on / off state of the dripping process and can be a conventional valve such as a ball valve, butterfly valve, or gate valve. Downstream of the switch valve 33, a liquid delivery pipeline 35 is connected. This liquid delivery pipeline 35 is equipped with a throttling valve 34 for precise control of the liquid flow rate, preferably a needle valve or a precision regulating valve, to achieve the requirement of slow dripping.

[0028] The mixing tank 2 has a through hole in its wall and is equipped with a liquid injection pipe 36, which connects the inside of the mixing tank 2 to the external liquid delivery pipe 35. The inner end of the liquid injection pipe 36 (i.e., the end that extends into the mixing tank) protrudes from the inner wall of the mixing tank 2, and its protrusion length L is preferably 5mm to 20mm. This design ensures that the liquid flowing out of the liquid injection pipe 36 can directly detach from the tank wall and drip into the material inside the mixing tank, effectively preventing the liquid from flowing along the tank wall. The liquid injection pipe 36 and the liquid delivery pipe 35 are detachably connected, for example, through a threaded joint or a quick-connect joint.

[0029] In a preferred embodiment, the mixing tank 2 may be provided with two injection pipes 36 on its wall. These two injection pipes 36 are arranged at a certain distance along the circumference of the mixing tank 2. Correspondingly, the dripping device 3 is also provided with two independent material tanks 31. Each material tank 31 is connected to one injection pipe 36 through an independent set of inlet pipes 35, a switching valve 33, and a throttle valve 34, thus forming two independent and controllable dripping systems. This configuration allows for the simultaneous or separate addition of two different liquid materials, or the addition of the same material from different points, thereby greatly improving the mixing uniformity and efficiency of high-viscosity materials.

[0030] The working principle of this utility model is as follows:

[0031] When it is necessary to add liquid to the high-viscosity material in the mixing tank 2, first open the switch valve 33 at the liquid outlet of the material tank 31, and then adjust the throttle valve 34 to a small opening so that the liquid in the material tank 31 flows into the mixing tank at a stable dripping rate under the action of gravity through the liquid delivery pipe 35 and the liquid injection pipe 36. Since the liquid injection pipe 36 protrudes from the inner wall, the liquid will drip directly into the material instead of flowing along the wall, thus being quickly and evenly dispersed under the action of the agitator.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
