Description

Technical Field

[0001] The utility model relates to the technical field of mixing and stirring equipment, in particular to a multifunctional mixer with an optional degassing path. Background Art

[0002] Mixers are widely used and are suitable for mixing and stirring raw materials for high-tech products such as light-emitting diodes, touch screens, medical devices, electronic components, fine chemical materials, printed electronic materials, electronic packaging materials and new energy materials.

[0003] Most of the raw materials being stirred have a certain viscosity, such as silicone, silver paste, aluminum paste, adhesives, ink, cosmetics, etc. During the stirring process of such viscous materials, the bubbles generated are not easy to dissipate quickly and naturally, affecting the quality of subsequent products.

[0004] The existing degassing methods in the industry mostly utilize stirring paddles and dispersion disks to disperse and stir the materials under the action of vacuum and high-speed dispersion. However, the degassing of bubbles by this method is limited and it is difficult to meet the technical requirements of small and few bubbles in the material. Utility Model Content

[0005] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a multifunctional mixer with a reasonable structure and an optional degassing path, which can effectively remove bubbles in the material through multiple targeted degassing.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A multifunctional mixer with an optional degassing path is provided with a degassing feeding path and a conventional feeding path; on the degassing feeding path, at least one degassing structure is arranged along the axial direction and radial direction of a mixer tank body.

[0008] As a further improvement of the above technical solution:

[0009] The degassing feeding path and the conventional feeding path are respectively provided with a degassing feeding port and a conventional feeding port which are independent of each other.

[0010] The degassing structure specifically includes:

[0011] The degassing plate is connected to the output end of the degassing feed port, and the degassing plate is rotatably assembled in the tank body.

[0012] Impact the degassing surface and receive the material thrown out by the degassing disc.

[0013] The dispersion stirring component is rotatably installed at the bottom of the tank body; the bubbles stirred and discharged by the dispersion stirring component are discharged from the vacuum port on the tank body cover.

[0014] The dispersion mixing assembly includes:

[0015] The dispersion main shaft is eccentrically arranged inside the tank, and the defoaming disc is connected to the dispersion main shaft.

[0016] The stirring paddle is coaxially arranged inside the tank.

[0017] The axial height of the defoaming disc inside the tank is close to the top of the tank.

[0018] The materials input into the tank through the defoaming feed port and the conventional feed port all flow from the position near the mouth inside the tank to the bottom of the tank.

[0019] In a single mixing condition, only one of the conventional feed port and the defoaming feed port is in use.

[0020] The beneficial effects of the present utility model are as follows:

[0021] The structure of the present utility model is compact and reasonable, and it is convenient to operate. There are three defoaming structures set in one device. Through centrifugal force to throw the materials and filter by the mesh surface, the first defoaming is realized; by throwing the materials on the wall surface, the second defoaming is realized; after the materials flow to the bottom of the container, under the action of the dispersion disc and the stirring paddle, the air bubbles float out and are taken away from the vacuum port, realizing the third defoaming.

[0022] The present utility model has two feeding paths. One passes through three defoaming structures in sequence, and the other bypasses the defoaming disc, with only one dispersion disc and stirring paddle acting, which is suitable for the working condition of thin raw materials that do not require defoaming or have a small amount of defoaming. In this way, the high applicability purpose of the present utility model is achieved. Description of the Drawings

[0029] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0030] like Figures 1-4 As shown, the multifunctional mixer with an optional degassing path of this embodiment is equipped with a degassing feeding path and a conventional feeding path; on the degassing feeding path, at least one degassing structure 4 is arranged along the axial and radial directions of the mixer tank body 1.

[0031] The degassing feeding path and the conventional feeding path are respectively provided with a degassing feeding port 2 and a conventional feeding port 3 which are independent of each other.

[0032] The degassing structure 4 specifically includes:

[0033] The degassing disc 401 is connected to the output end of the degassing feed port 2, and the degassing disc 401 is rotatably assembled in the tank body 1.

[0034] The impact degassing surface 402 receives the material thrown out by the degassing plate 401.

[0035] The dispersion stirring component is rotatably installed at the bottom of the tank body 1; the bubbles stirred and discharged by the dispersion stirring component are discharged from the vacuum port on the head of the tank body 1.

[0036] The dispersion mixing assembly includes:

[0037] The dispersion main shaft 403 is eccentrically arranged in the tank body 1, and the degassing disk 401 is connected to the dispersion main shaft 403.

[0038] The stirring paddle 404 is coaxially arranged in the tank body 1 .

[0039] The axial height of the degassing disk 401 in the tank body 1 is close to the top of the tank body 1 .

[0040] The materials input into the tank body 1 through the degassing feed port 2 and the conventional feed port 3 all flow from the inside of the tank body 1 near the mouth to the bottom of the tank body 1 .

[0041] In a single mixing condition, only one of the conventional feed inlet 3 and the degassing feed inlet 2 is put into use.

[0042] The specific structure and working principle of the utility model are as follows:

[0043] like Figure 1 As shown, it is a cross-sectional view of the utility model with a degassing feed port 2, Figure 2 It is a cross-sectional view with a conventional feed port 3.

[0044] The tank body 1 has a sealing head on the top, and a vacuum port is arranged on the sealing head. Excess gas in the tank body 1 is discharged from the vacuum port. For example, bubbles discharged by stirring the material in the tank body 1 are discharged from the vacuum port.

[0045] The advantage of this solution is that a tank body 1 is provided with two feeding paths, which are respectively applicable to materials that need to be degassed and materials that do not need to be degassed. There are three degassing links arranged on the degassing feeding path, and degassing is carried out during the feeding process and during the storage and stirring process in the tank body 1. The conventional feeding path avoids the first two degassing links and is only stirred and dispersed in the tank body 1.

[0046] Taking the degassing feeding path as an example, with reference to Figure 1 , a degassing feeding port 2 is installed on the head. The degassing feeding port 2 is provided with a pipe, and the pipe is introduced into the tank body 1 and has a certain distance from the inner wall of the tank body 1 to adapt to the position of the degassing disc 401.

[0047] A dispersion main shaft 403 is arranged eccentrically in the tank body 1. A degassing disc 401 is coaxially installed at a position of the dispersion main shaft 403 close to the mouth of the tank body 1. The structure of the degassing disc 401 refers to Figure 3 , which is an open disc. The bottom of the degassing disc 401 is solid, and the circumferential surface is a mesh surface. The degassing feeding port 2 is led to the degassing disc 401. The degassing disc 401 is driven by the dispersion main shaft 403 to throw the materials in the disc out. The materials are Figure 4 cut by the mesh surface shown in

[0048] to break the bubbles in the materials and discharge the gas, completing the first degassing. The materials after the first degassing leave the degassing disc 401 under the action of centrifugal force and impact on the inner wall of the tank body 1. This inner wall is the impact degassing surface 402. The materials complete the second degassing after impact, and then gradually flow downward along the wall surface to the bottom of the tank body 1, where they are stirred by the stirring paddle 404 at the bottom of the tank body 1 and dispersed by the dispersion main shaft 403 at the same time. The third degassing is completed during the stirring and dispersion process. The bubbles float to the surface of the materials, and the gas is discharged through the vacuum port. Figure 2 If the materials do not need to be degassed or the degassing difficulty is low and the bubbles are easy to discharge, they enter from the other feeding port, that is, the conventional feeding port 3 in

[0049] . The conventional feeding port 3 is arranged on the head and is guided by a feeding pipe to a position close to the wall surface. A certain distance is reserved between the mouth of the feeding pipe and the wall surface for the materials to flow out. The materials flow into the bottom of the tank body 1 along the wall surface through the conventional feeding port 3 and are dispersed and stirred by the dispersion disc and the stirring paddle 404.
