Abstract
Self-absorbing filtering device before a kind of pump of the utility model, it is characterized by comprising cavitys, the cavity is enclosed construction, filter screen is provided in the cavity, the cavity is separated into upper cavity and lower chamber by the filter screen, the lower chamber is connected to the pump housing, and the upper cavity is communicated with feed pipe, and the feed pipe can be inserted into material.With backwash and filtering function.
Description
Technical field
The utility model relates to material transportation fields, more particularly to pump preceding self-absorbing filtering device.
Background technique
Pump has a wide range of applications in fields such as industry, agriculturals, and structure is simple, and easy to operate wait is used for material transportation mistake
Journey.But since most of pumps do not have self-priming kinetic energy, especially water pump is this kind of, need to be after substance and feed pipe are all infused and need logistics
It can just run or material is apparently higher than the pump housing.There are also since material clamp is with solid impurity, brought very in pump housing operation
Good destruction, leads to troublesome in poeration, the service life reduction of pump.
Therefore, how to a kind of device is designed, it is made to overcome the above problem, be those skilled in the art it is urgently to be resolved one
A problem.
Utility model content
Self-absorbing filtering fills before a kind of pump with backwash and filtering function that one of the utility model is designed to provide
It sets.
To achieve the above objectives, the technical solution adopted in the utility model are as follows: self-absorbing filtering device before a kind of pump, feature
Be: including cavity, the cavity is enclosed construction, is provided with filter screen in the cavity, and the filter screen is by the cavity
It is separated into upper cavity and lower chamber, the lower chamber is connected to the pump housing, and the upper cavity is communicated with feed pipe, and the feed pipe can be inserted
Enter in material.
As an improvement, the upper cavity upper end is provided with sprue.Sprue is used for the material filling into cavity for the first time, Yi Jifang
Just it repairs.
It is further improved, the upper cavity upper end is additionally provided with vacuum meter.Real-time display cavity internal pressure situation, so that work
The unexpected situations such as blocking, leakage can be found in time by making personnel.
Preferably, the filter screen sinks to forming bag shaped structure.The filter screen of bag shaped structure has bigger filtering surface
Product can disposably accommodate more materials, improve filter efficiency；And the filter screen of bag shaped structure can accommodate it is more filtered
Solid impurity reduces the frequency of replacement or cleaning filter screen.
Compared with the prior art, the advantages of the utility model are: after the device that the pump housing connects this programme, in cavity
When inside having material, material is exported via the pump housing, and liquid level declines in cavity, so that cavity generates vacuum or negative pressure, while feed pipe
It is inserted into material, under atmospheric pressure, material is drawn onto upper cavity from feed pipe automatically, using strainer, reaches cavity of resorption
Body, and exported through the pump housing, form circulation.By above structure, it can make the pump housing that there is self-suction function, not need in the pump housing
Injecting material can operate normally；And the presence due to there is filter screen, solid impurity is filtered out, the pump housing is hardly damaged, it is both simple
Single operation, and extend the service life of the pump housing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of a preferred embodiment according to the present utility model.
Specific embodiment
It is described below for disclosing the utility model so that those skilled in the art can be realized the utility model.It retouches below
Preferred embodiment in stating is only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.
In the description of the present invention, it should be noted that for the noun of locality, if any term " center ", " transverse direction ",
" longitudinal direction ", " length ", " width ", " thickness ", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top",
The indicating positions such as "bottom", "inner", "outside", " clockwise ", " counterclockwise " and positional relationship are orientation based on the figure or position
Relationship is set, narration the utility model is merely for convenience of and simplifies description, rather than the device or element of indication or suggestion meaning
It must have a particular orientation, constructed and operated with particular orientation, should not be understood as the specific protection model for limiting the utility model
It encloses.
As shown in Figure 1, a preferred embodiment of the utility model includes cavity 1, cavity 1 is enclosed construction, in cavity 1
It is provided with filter screen 4, cavity 1 is separated into upper cavity 11 and lower chamber 12 by filter screen 4, and lower chamber 12 is connected to the pump housing 100, epicoele
Body 11 is communicated with feed pipe 2, and feed pipe 2 can be inserted into material.
In addition, 11 upper end of upper cavity is provided with sprue 3 for material feeding for the first time and easy to maintenance.
In order to implement to show cavity internal pressure, 11 upper end of upper cavity is additionally provided with vacuum meter 5.
In the present embodiment, the sinking of filter screen 4 forms bag shaped structure.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only the principles of the present invention, the utility model also has respectively on the premise of not departing from the spirit and scope of the utility model
Kind changes and improvements, these changes and improvements are both fallen in the range of claimed invention.The requires of the utility model
Protection scope defined by appended claims and its equivalent.
