Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chemical equipment technology, specifically a feeding and mixing device. Background Technology
[0002] The reactor feed must ensure that DMCD is thoroughly mixed. If these materials are not mixed evenly, the reaction effect within the reactor will be significantly reduced.
[0003] The process of mixing materials usually relies on a mixer, which inevitably requires the use of mixing equipment to ensure thorough mixing. This process also consumes a lot of electricity, and the cost of using and maintaining the mixer is relatively high.
[0004] The applicant is a large-scale chemical production enterprise. In order to better save energy, the applicant has made corresponding modifications to the existing equipment structure. By using a static mixer, the mixing efficiency has been improved to meet the needs of chemical production. The modified static mixer structure has resulted in good mixing effect.
[0005] Currently, material mixing mainly relies on agitation technology. Typically, agitators are driven by electric motors, a process that consumes a significant amount of electricity. Furthermore, agitators operate under relatively strict conditions, requiring high liquid levels in the storage tank. Levels that are too high or too low can damage the agitator. In addition, critical components of the agitator, such as the shaft, impellers, mechanical seals, and motor, are prone to wear, necessitating regular maintenance and repairs, which undoubtedly increases maintenance costs. In contrast, static mixers can effectively reduce these maintenance and operating costs. Utility Model Content
[0006] To address the problems mentioned in the background section, this utility model provides a feeding and mixing device, the technical solution of which is as follows:
[0007] A feeding and mixing device includes a buffer tank, a filter, and a circulating pump. The buffer tank is connected to the filter via a pipeline. The filter is used to filter impurities in the material. The filter is connected to the circulating pump via a pipeline. The circulating pump is used to provide material flow. The circulating pump is connected to the buffer tank via a pipeline.
[0008] The core improvement of this utility model is as follows: a static mixer is provided in front of the buffer tank. The static mixer is used to fully mix the materials. The static mixer includes a shell with at least two or more feed ports. The number of feed ports can be adjusted according to the actual amount of materials, such as two, three, four...N. The shell is equipped with a packing support plate and packing. The packing is used to mix the materials better.
[0009] Preferably, there are three feed inlets: feed inlet one, feed inlet two, and feed inlet three.
[0010] Preferably, in order to prevent the material from solidifying, the outer surface of the shell is provided with a jacket. The jacket is used to provide a heat source to prevent the material from solidifying. According to the material characteristics, the material will solidify and become unable to flow if the temperature is lower than the melting point, so a jacket is required.
[0011] After the materials are premixed in the pipeline, the packing material is used to make the three materials, methanol, light components and DMCD, more fully mixed.
[0012] The material inlet is equipped with a guide plate, the packing support plate has uniformly opened holes, and multiple layers of packing fill the mixing chamber. The jacketed heat tracing pipe provides a stable heat source to prevent the material from solidifying.
[0013] Preferably, in order to achieve a better flow splitting effect, the housing is provided with a plurality of flow splitting and mixing components, one side of which is a conical structure.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the structural modification of this utility model, materials can be better mixed evenly through the static mixer, and materials can be mixed evenly without stirring equipment. In practical applications, the effect is better, achieving the purpose of energy saving and environmental protection. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Example 1
[0020] like Figure 1 , Figure 2 shown
[0021] A feeding and mixing device includes a buffer tank 2, a filter 4, and a circulating pump 3. The buffer tank 2 is connected to the filter 4 via a pipeline, the filter is connected to the circulating pump 3 via a pipeline, and the circulating pump 3 is connected to the buffer tank 2 via a pipeline. A static mixer 1 is provided in front of the buffer tank 2. The static mixer 1 includes a shell with at least three feed inlets. The shell is equipped with a packing support plate 1-4 and packing 1-5 inside, which are feed inlet 1-1, feed inlet 1-2, and feed inlet 1-3, respectively. The outer surface of the shell is equipped with a jacket 1-6, and the shell is equipped with a plurality of diversion mixing components 1-7 inside. One side of the diversion mixing components 1-7 is a conical structure.
[0022] The working principle of this utility model is as follows: Material 1 is methanol, material 2 is light component, and material 3 is DMCD. The light component and DMCD are initially mixed, and then mixed again with methanol after being separated and mixed by the diversion mixing components 1-7. After the three materials are fully mixed, they are mixed again by the diversion mixing components 1-7 and then mixed by the packing 1-5 before flowing out from the outlet. Then they are buffered by the buffer tank 2, and finally filtered by the filter 4 to remove impurities before being transported to the downstream equipment.
[0023] First, material one refers to methanol, material two refers to the light component, and material three is DMCD. During the mixing process, the light component and DMCD undergo initial mixing. Next, the mixed light component and DMCD enter the diversion mixing assembly 1-7 and proceed to the next mixing chamber. Afterward, the initially mixed light component and DMCD are mixed again with methanol. The uniformly mixed material then enters the packing material 1-5, where further mixing ensures optimal mixing before final output. The uniformly mixed material flows out from the outlet and then enters the buffer tank 2 for buffering treatment to stabilize the material's flowability and pressure.
[0024] After buffering, the material is filtered through filter 4 to remove impurities and impurities, ensuring its purity. Finally, the filtered material is conveyed to downstream equipment for further production or processing. The entire process, through precise control and optimized mixing, diversion, buffering, and filtration steps, ensures the quality and performance of the final product.
