Abstract

The utility model discloses an improved structure of a fluid filtering passage. The improved structure of the fluid filtering passage comprises a fluid sucking mechanism and a fluid filtering mechanism; and the fluid sucking mechanism is communicated with the fluid filtering mechanism through the fluid passage. The utility model is characterized in that the improved structure of the fluid filtering passage further comprises a negative pressure sensing mechanism which is communicated with the fluid passage; the negative pressure sensing mechanism is connected with a control unit; and the fluid sucking mechanism is controlled by the control unit. The improved structure of the fluid filtering passage has the advantages that through arranging the negative pressure sensing mechanism in the fluid passage, when the fluid filtering mechanism is blocked and negative pressure generated in the fluid passage exceeds a safety value, the fluid sucking mechanism is stopped working and/or a caution is sent to operators, thus the damage to equipment and the occurrence of a dangerous condition are avoided; and in addition, the improved structure of the fluid filtering passage can save energies and is safe and environment-friendly.

Description

Filtering flow passage structure-improved

Technical field

The utility model relates to a kind of filtering flow equipment, relates in particular to a kind of filtering flow equipment with improvement filtering flow channel design.

Background technology

Be the online impurity such as particle contained in the fluid, dust of removing, people need to be provided with filtration usually in the fluid passage.Be a kind of filtering flow equipment of commonly seeing as shown in Figure 1, it comprises filter mechanism 2 and the fluid sucker mechanism 3 that is arranged at 1 two ends, fluid passage respectively, the fluid sucker mechanism produces negative pressure in the fluid passage in the course of the work, make extraneous fluid continue to enter the fluid passage after mechanism's filtration after filtration, and export in storage container or the particular space by the fluid sucker mechanism.Then, this type of filtering flow equipment in long-term work or continue to handle contain the fluid of high concentration particle, dust etc. after, filter mechanism tends to blocked, and then cause fluid sucker mechanism continuing spinning, and inside and outsidely in the fluid passage cause excessive pressure reduction, therefore both can waste energy, also may cause equipment damage and security incident.

The utility model content

The purpose of this utility model is to provide a kind of filtering flow passage structure-improved, and it can effectively prevent idle running of fluid sucker mechanism and the excessive problem of the inside and outside pressure reduction of filtering flow passage.

For realizing above-mentioned utility model purpose, the utility model has adopted following technical scheme:

A kind of filtering flow passage structure-improved, comprise fluid sucker mechanism and filtering flow mechanism, described fluid sucker mechanism is communicated with through the fluid passage with filtering flow mechanism, it is characterized in that: described filtering flow passage structure-improved also comprises the negative pressure induction mechanism that is communicated with the fluid passage, described negative pressure induction mechanism is connected with a control module, and described fluid sucker mechanism is controlled by described control module.

Preferably, described negative pressure induction mechanism and/or control module also are connected with at least one caution mechanism.

As a kind of preferred implementation, described negative pressure induction mechanism comprises piston piece that places in the pipeline that is communicated with described fluid passage and the displacement sensor that cooperates with described piston piece, and described displacement sensor is connected with control module.

Described negative pressure induction mechanism adopts the negative pressure inductor.

Compared with prior art, advantage of the present utility model is: by the negative pressure induction mechanism is set in the fluid passage, in the time of can stopping up in filtering flow mechanism, and when the negative pressure that produces in the fluid passage surpasses safety value, make the fluid sucker mechanism quit work and/or send caution, thereby the equipment of having stopped is undermined the generation of unsafe condition to operating personnel.

Description of drawings

Fig. 1 is the structural representation of filtering flow equipment in the prior art;

Fig. 2 is the structural representation of the utility model embodiment 1;

Fig. 3 is the structural representation of the good embodiment 2 of the utility model;

Each assembly and Reference numeral thereof are respectively among the figure: fluid passage 1, filtering flow mechanism 2, fluid sucker mechanism 3, pipeline 41, piston piece 42, displacement sensor 43, control module 5, caution mechanism 6 and negative pressure inductor 7.

The specific embodiment

Embodiment 1 consults Fig. 2, this filtering flow equipment comprises fluid sucker mechanism 2 and filtering flow mechanism 3, this fluid sucker mechanism 2 and filtering flow mechanism 31 are communicated with through the fluid passage, and also be provided with a negative pressure inductor 7 on this fluid passage, this negative pressure inductor 7 is connected with a control module, and this fluid sucker mechanism is by this control module control.Preferably, this control module 5 also is connected with caution mechanism 6.This filtering flow equipment is in when work, if filter plant is blocked, and when the negative pressure inductor detects pressure in the fluid passage and is lower than secure threshold, then makes the fluid sucker mechanism out of service by control module, gives the alarm simultaneously.

Embodiment 2, consult Fig. 3, this filtering flow equipment comprises fluid sucker mechanism 2 and filtering flow mechanism 3, this fluid sucker mechanism 2 and filtering flow mechanism 31 are communicated with through the fluid passage, and this fluid passage also is communicated with a pipeline 41, one piston piece 42 is installed in this pipeline, and this piston piece cooperates with a displacement sensor 43, and this displacement sensor is connected with control module 5.Preferably, this control module also is connected with caution mechanism 6.This filtering flow equipment is when work, if filter plant is blocked, and when fluid passage internal pressure during less than secure threshold, then piston piece slip in pipeline under the promotion of fluid passage outer fluid (otherwise, if the fluid passage internal pressure is greater than secure threshold, then piston piece keeps static condition), the displacement sensor that cooperates with it sends a signal to control module simultaneously, make the fluid sucker mechanism out of service by control module again, give the alarm simultaneously.Adopt the design of present embodiment; can prevent that on the one hand filter mechanism from stopping up the danger that causes; on the other hand also can be when filter mechanism stops up; by the action of piston piece the fluid in the pipeline is imported in the fluid passage; make the fluid sucker mechanism need not to shut down rapidly, thereby prevent the anxious damage that the convection cell sucker mechanism causes that stops.The aforementioned displacements inductor can adopt contact or contactless displacement inductor.

Aforesaid fluid sucker mechanism 2 can be all kinds of pumps of commonly seeing or negative-pressure air fan etc., the aforesaid fluid filter mechanism then adopts gas, the filter apparatus for filtering liquid of commonly seeing, aforesaid pressure inductor can adopt at present commercially available all kinds of air pressure, hydrostatic sensor etc., and caution mechanism can adopt common sound, light class alarm etc.In addition, aforementioned control module can adopt single-chip microcomputer or other control kind equipment, but preferably adopts computer system etc., by with this computer system access to LAN or internet, also can carry out long-range caution or controls.

Need to prove that previous embodiment only is explanation technical conceive of the present utility model and characteristics, its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed within the protection domain of the present utility model.
