Abstract
The utility model provides a vacuumizing unit of a vacuum flask inner container. The vacuumizing unit comprises slide valve pumps, a convex diffusion pump, a vacuum chamber, a water block, vacuum flapper valves, vacuumizing main pipes and a roots pump. The slide valve pumps are correspondingly arranged on two sides of the convex diffusion pump. The convex diffusion pump is respectively connected with the slide valve pumps on the two sides of the convex diffusion pump through pipelines. The roots pump is correspondingly installed on one pipeline which connects the convex diffusion pump with one slide valve pump on one side of the convex diffusion pump. The vacuum chamber is connected with the top of the convex diffusion pump through the water block. A pair of vacuum flapper valves is installed on the top of the vacuum chamber. The pair of the vacuum flapper valves is respectively correspondingly connected with the vacuumizing main pipes. According to the scheme, due to the fact that the height of the convex diffusion pump is relatively low, the convex diffusion pump is needless to be sunk under the ground when installed, accordingly installation is simple, and maintenance is convenient. In addition, due to the fact that the roots pump is additionally arranged on the vacuumizing unit, the vacuum degree and efficiency are greatly improved, and product quality can be effectively guaranteed.
Description
Technical field
The utility model relates to the technical field of vacuum flask manufacturing mechanism, refers in particular to a kind of unit that vacuumizes of inner container for thermos flask.
Background technique
Known in the industry, the existing unit that vacuumizes for inner container for thermos flask, because the deficiency in its design, be confined to this body structure, so that its ubiquity degree of vacuum is unstable, efficient is low, quality of product is difficult to the shortcomings such as assurance, wherein, comparatively serious is that traditional unit that vacuumizes is installed extremely inconvenient, need to dig a well in factory building during installation, the easy like this workshop of causing is untidy, and difficulty is done cleaning maintenance service work.Therefore, in sum, how effectively to solve installation and the quality problems of evacuator group now, become the major issue that the researcher is badly in need of solving.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of unit that vacuumizes of reliable, easy to maintenance, degree of vacuum is high, efficient is high inner container for thermos flask reasonable in design is provided.
For achieving the above object, technological scheme provided by the utility model is: a kind of inner container for thermos flask vacuumize unit, it includes slide valve pump, protruding diffusion pump, vacuum chamber, water-cooling head, vacuum flapper valve, vacuumizes supervisor, Roots pump, wherein, described slide valve pump correspondence is located at the both sides of protruding diffusion pump, and this protruding diffusion pump joins with the slide valve pump of its both sides respectively by pipeline, simultaneously, the Roots pump correspondence is installed on the pipeline that this protruding diffusion pump and a side sliding valve pump join; Described vacuum chamber joins by the top of water-cooling head and above-mentioned protruding diffusion pump, simultaneously, on the top of this vacuum chamber a pair of vacuum flapper valve is installed, and, this to vacuum flapper valve respectively with vacuumize accordingly separately supervisor join.
The described supervisor's of vacuumizing bilateral symmetry is equipped with a plurality of vacuum valves of arranging side by side.
The utility model is after having adopted such scheme, its great advantage is because the height of protruding diffusion pump of the present utility model is lower, so that it need not sink to subsurface when installing, namely is to dig a well on the ground, thereby so that it is installed simply, maintenance service is convenient; In addition, because the utility model has additional Roots pump, for the characteristics of Roots pump itself, so that degree of vacuum of the present utility model and efficient have obtained greatly raising, thereby can effectively guarantee quality of product.
Description of drawings
Fig. 1 is plan view of the present utility model.
Fig. 2 is plan view of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
Shown in accompanying drawing 1 and accompanying drawing 2, the described inner container for thermos flask of the present embodiment vacuumize unit, it includes slide valve pump 1, protruding diffusion pump 2, vacuum chamber 3, water-cooling head 4, vacuum flapper valve 5, vacuumizes supervisor 6, Roots pump 7, wherein, described slide valve pump 1 correspondence is located at the both sides of protruding diffusion pump 2, and this protruding diffusion pump 2 joins with the slide valve pump 1 of its both sides respectively by pipeline, simultaneously, Roots pump 7 correspondences are installed on the pipeline that this protruding diffusion pump 2 and a side sliding valve pump 1 join; Described vacuum chamber 3 joins by water-cooling head 4 top with above-mentioned protruding diffusion pump 2, simultaneously, a pair of vacuum flapper valve 5 is installed on the top of this vacuum chamber 3, and, this to vacuum flapper valve 5 respectively with vacuumize accordingly separately supervisor 6 and join.In addition, the bilateral symmetry that the present embodiment is above-mentioned to vacuumize supervisor 6 is equipped with a plurality of vacuum valves of arranging side by side 8, when being used for vacuumizing and the vacuum-pumping tube of inner container for thermos flask join.In sum, after adopting above scheme, because the height of protruding diffusion pump 2 of the present utility model is lower, so that it need not sink to subsurface when installing, namely be to dig a well on the ground, thereby so that it installs simply, maintenance service is convenient; In addition, because the utility model has additional Roots pump 7, (Roots pump has very large pumping speed in very wide pressure range for Roots pump 7 characteristics own, start fast, can discharge rapidly the gas that is distilled, and vacuum at short notice can reach capacity), so that degree of vacuum of the present utility model and efficient have obtained greatly improving, thereby can effectively guarantee quality of product, this compared to existing technology, the utility model efficiently solves installation and the quality problems that prior art exists, and is a kind of economical and practical novel unit that vacuumizes, and is worthy to be popularized.
The examples of implementation of the above are the preferred embodiment of the utility model only, are not to limit practical range of the present utility model with this, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the present utility model.
