Description

Disposable stirring and filtering device

Technical Field

The utility model provides a disposable stirring and filtering device matched with an autorotation and revolution stirrer, and belongs to the technical field of filtering.

Background

Pressure filtration through a metal mesh is an essential unit of operation in the production of high viscosity adhesives, especially adhesives containing solid particulate fillers. However, in the case of preparing a small amount of adhesive samples in a laboratory, the pressure filtration with a common metal mesh often results in more loss of the adhesive samples, and the filtered adhesive samples are also mixed with a large amount of bubbles, which affects the quality. The used container is also required to be cleaned, and a large amount of solvent is used, so that the environment is not protected, and the safety is not high.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a disposable stirring and filtering device matched with a rotation and revolution stirrer.

The utility model provides a disposable stirring and filtering device which comprises a disposable filtering container and a filtering net arranged on the filtering container.

Preferably, the apparatus further comprises an outer container for holding the filtration vessel.

Specifically, the hardness of the outer container for containing the filtering container is greater than that of the filtering container, and hard plastics, metal materials and the like can be adopted.

Preferably, the filtering container comprises a disposable plastic cup and a disposable paper cup.

Preferably, the filter screen includes filtering end and stiff end, and the stiff end setting is at filtering container top, and filtering end is located inside the filtering container.

Preferably, the filter screen includes metal filter screen and plastic filter screen, and the mesh can use 50~350 meshes as required.

Preferably, the device is arranged on the rotation and revolution stirrer.

Compared with the prior art, the disposable stirring and filtering device provided by the utility model is used for a rotation and revolution stirrer, can be used for stirring and filtering a small amount of adhesive samples (5-50 g), and is high in filtering speed and capable of being completed within a few minutes. The filtered adhesive sample is uniform and fine, and has no solid particles and no bubbles. The filter screen and the plastic cup are disposable and can be used as industrial waste to be disposed of after being used up, so that the operation time is greatly saved, the whole process is simple, convenient and quick, and the filter screen and the plastic cup are safe and environment-friendly.

Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and other drawings can be obtained by those skilled in the art according to the drawings.

The revolution mixer uses high-speed revolution of more than 2000rpm and rotation of 800rpm to mix and defoam the materials in a moment, the clay with extremely high viscosity can be fully mixed in a few minutes under the acceleration of gravity of 400G, even the high-viscosity epoxy resin adhesive which is difficult to stir can be stirred into a uniform mixture in a short time, and no bubbles are generated under the observation of a microscope.

The disposable stirring and filtering device is arranged on a rotation and revolution stirrer, and the working process of the disposable stirring and filtering device is shown in figure 1.

With reference to fig. 2 to 4, the present invention improves the existing filtering device by using a disposable plastic cup or paper cup as a filtering container 2-3, and the filtering container 2-3 is provided with a filtering net 2-1 to form the disposable filtering device. The filter screen 2-1 can be a plastic filter screen or a metal filter screen, and the mesh can be 50-350 meshes or a thinner or thicker filter screen according to requirements. The filter screen 2-1 comprises a filter end and a fixed end, the fixed end is fixed at the top of the filter container 2-3, the filter end is positioned inside the filter container 2-3, the filter screen 2-1 is made into a shape matched with the filter container 2-3 according to the used material (plastic or metal), and the cross section structure schematic diagram is shown in fig. 2 and fig. 3. In order to prevent the filter screen 2-1 from falling off during high-speed rotation and revolution, the fixed end of the filter screen 2-1 generally needs to be fixed, and particularly, for a plastic filter screen with weak mechanical strength, after the plastic filter screen is arranged in the filter container 2-3, the plastic filter screen can be fixed on the top of the filter container 2-3 by using an adhesive tape, a rubber band or a metal wire, a metal ring and the like. For better filtering effect, the distance between the filtering end of the filtering net 2-1 and the top of the filtering container 2-3 is 1/4 to 1/2 of the height of the filtering container 2-3. Because the disposable plastic cup or paper cup is used as the filtering container 2-3, the hardness is relatively low, the disposable plastic cup or paper cup is not easy to be fixed in the rotation and revolution stirrer, and the problem of cracking and the like is easy to occur in the high-speed rotation and revolution process, an outer container (as shown in figure 4) matched with the filtering container 2-3 is needed to be arranged, and the outer container is made of hard plastics and metal materials with relatively high hardness. The size of the filter is matched with that of the filter containers 2-3.

The specific working process of the disposable stirring and filtering device is as follows: the method comprises the steps of weighing and adding the uniformly dispersed high-viscosity adhesive (material) to be filtered into a filtering container of a disposable stirring and filtering device, placing the filtering container into an outer container, weighing, placing the filtering container into a rotation and revolution stirrer (a single-cup stirrer or a double-cup stirrer can be adopted), adjusting a balance weight, starting a stirring mode, and obtaining a filtered adhesive sample in a few minutes.

Or adding the materials of the components of the adhesive formula into a filtering container of a disposable filtering device respectively without stirring or simply stirring by using disposable chopsticks, placing the filtering container into an outer container, weighing, putting the filtering container into a rotation and revolution stirrer together, adjusting a balance weight, starting a stirring mode, stirring and mixing while filtering to obtain an adhesive sample without bubbles and uniformly mixed. The stirring time is saved.

The disposable filtering device disclosed by the utility model is simple to manufacture, low in cost, free of material loss, free of cleaning after filtering, energy-saving, environment-friendly, safe and convenient, can be used for filtering a small amount of adhesive samples, greatly reduces the preparation time of the adhesive samples, simplifies the preparation process and improves the sample manufacturing efficiency.
