Abstract
The utility model relates to a core crucible which comprises a crucible shell, core and a connecting grinding mouth. The core is arranged inside the crucible shell; the connecting grinding mouth is located at the underside of the bottom of the crucible shell and is arranged on the bottom of the crucible shell to be directly sleeved and connected with a grinding mouth of a filter flask; the crucible shell is communicated with the connecting grinding mouth through a core liquid path. Preferentially, the crucible shell is a glass shell; the connecting grinding mouth is a glass grinding mouth; and the connecting grinding mouth is an external grinding mouth or internal grinding mouth; the crucible shell and the connecting grinding mouth are integrally molded; and the core is arranged at the bottom in the crucible shell. The core crucible is ingenious in design, concise in structure and convenient to use, and can be quickly connected with the filter flask, and air leakage does not occur easily, so the efficiency and the speed of suction filtration are improved. Therefore, the core crucible is suitable for large-scale popularization and application.
Description
Technical field
The utility model relates to filtration art, and particularly the filter technology field specifically refers to a kind of core crucible.
Background technology
Existing core crucible is a kind of glass filter (glass core filter), is to adopt fine quality glass for chemical ware manufacturing, has good physical and chemical performance.Be applicable to the filtration of the aspect different materials such as chemical analysis, sanitary inspection, pharmaceuticals industry, biological products.
But the bottom of existing core crucible is to adopt smooth glass as link, is connected with bottle,suction by the rubber leather cup.But assembling is inconvenient, in assembling process, leaks gas easily, affects efficient and the speed of suction filtration.
Therefore, need to provide a kind of core crucible, it is easy to use, can be connected fast with bottle,suction, is not easy gas leakage, thereby improves efficient and the speed of suction filtration.
The utility model content
The purpose of this utility model is to have overcome above-mentioned shortcoming of the prior art, and a kind of core crucible is provided, and this core crucible design is ingenious, simple for structure, easy to use, can be connected fast with bottle,suction, be not easy gas leakage, thereby improve efficient and the speed of suction filtration, be suitable for large-scale promotion application.
To achieve these goals, core crucible of the present utility model, comprise crucible housing and core, described core is arranged in the described crucible housing, be characterized in, described core crucible also comprises the connection ground, described connection ground be positioned at bottom following of described crucible housing and be installed in the bottom upper be used for directly being socketed with the ground of bottle,suction be connected, described crucible housing is communicated with described connection ground by described core liquid road.
Described " connection ground " refers to be complementary with the ground of bottle,suction and directly is socketed the ground that is connected.Because the ground of existing bottle,suction is the standard ground, specification mainly contains 12#, 14#, 19#, 24#, 34#, 40#, 45#, 50#, therefore correspondingly, the connection ground of core crucible of the present utility model also is the standard ground, and specification mainly contains 12#, 14#, 19#, 24#, 34#, 40#, 45#, 50#.
Preferably, described crucible housing is glass shell.
Preferably, described connection ground is glass ground joint.
Preferably, described connection ground is outer grinding port or interior ground.
Preferably, described crucible housing is with to be connected the connection ground integrally formed.
Preferably, described core is arranged in the bottom of described crucible housing.
The beneficial effects of the utility model specifically are: core crucible of the present utility model comprises the crucible housing, core be connected ground, described core is arranged in the described crucible housing, described connection ground is positioned at bottom following of described crucible housing and is installed on the bottom, described crucible housing is communicated with described connection ground by described core liquid road, thereby can be connected with various standard ground bottle,suctions easily by connecting ground, design ingenious, simple for structure, easy to use, can be connected fast with bottle,suction, be not easy gas leakage, thereby improve efficient and the speed of suction filtration, be suitable for large-scale promotion application.
Description of drawings
Fig. 1 is that the master of the first specific embodiment of the present utility model looks schematic diagram.
Fig. 2 is that the master of the second specific embodiment of the present utility model looks schematic diagram.
The specific embodiment
In order more clearly to understand technology contents of the present utility model, describe in detail especially exemplified by following examples.
See also Fig. 1-shown in Figure 2, core crucible of the present utility model comprises crucible housing 1, core 2 and is connected ground 3, described core 2 is arranged in the described crucible housing 1, described connection ground 3 is positioned at bottom following of described crucible housing 1 and is installed on the bottom, and described crucible housing 1 is communicated with described connection ground 3 by described core 2 liquid roads.
Described crucible housing 1 can adopt any suitable housing, sees also Fig. 1-shown in Figure 2, and in the first and second specific embodiments of the present utility model, described crucible housing 1 is glass shell.
Described connection ground 3 can adopt any suitable ground, sees also Fig. 1-shown in Figure 2, and in the first and second specific embodiments of the present utility model, described connection ground 3 is glass ground joint.
Described connection ground 3 can be outer grinding port, also can be interior ground, can determine as required.See also shown in Figure 1ly, in the first specific embodiment of the present utility model, described connection ground 3 is outer grinding ports.When being connected with bottle,suction, be plugged in the standard ground (for interior ground) of bottle,suction.See also shown in Figure 2ly, in the second specific embodiment of the present utility model, described connection ground 3 is interior grounds.When being connected with bottle,suction, be socketed in outside the standard ground (for outer grinding port) of bottle,suction.
Described crucible housing 1 be connected connection ground 3 and can be individual components, described connection ground 3 is installed on the described crucible housing 1, also can be integrally formed, see also Fig. 1-shown in Figure 2, in the first and second specific embodiments of the present utility model, described crucible housing 1 is with to be connected connection ground 3 integrally formed.
Described core 2 is arranged in the described crucible housing 1 can be arranged on any suitable position, sees also Fig. 1-shown in Figure 2, and in the first and second specific embodiments of the present utility model, described core 2 is arranged in the bottom of described crucible housing 1.
When the utility model uses, connection ground 3 of the present utility model directly pegged graft with the standard ground of bottle,suction or socket is connected and can carries out suction filtration, very convenient quick, difficult gas leakage.
