Abstract
The utility model provides a solvent conveying device. The solvent conveying device is characterized in that a pipeline used for connecting a solvent tank and a workshop is included, and the pipeline from the solvent tank to the workshop is sequentially connected with a filter, a diaphragm pump and one or two one-way valves. According to the solvent conveying device, the one-way valves are additionally arranged based on an original solvent conveying device, after the one-way valves are arranged on the diaphragm pump, the phenomenon that the solvent can flow back after thermal expansion to flow backwards into the diaphragm pump can be effectively avoided, the diaphragm pump is effectively protected, and the service life of the diaphragm pump is prolonged.
Description
Technical field
The utility model relates to Printing ink producing equipment technical field, is specifically related to a kind of solvent conveyer for Printing ink producing.
Background technology
The flow process of Printing ink producing comprises that printing ink solvent is prepared to workshop from solvent to be carried to stirring, grinding, packing shop.Generally, delivery duct is embedded in underground.But in In Guangdong Province, because soil moisture is larger, temperature is higher, instead piping laying can be accelerated to the aging of pipeline in underground, so Printing ink producing producer usually selects pipeline to be suspended in the air simultaneously throughout the year.But this brings again new problem, more obvious owing to expanding with heat and contract with cold in air exactly, therefore, after expanding, the solvent heat in pipeline easily refluxes, and the membrane pump arranging on pipeline is produced and pours in down a chimney damage.
Utility model content
In view of this, be necessary the problem mentioned for background technology, the conveyer that provides a kind of novel prevented solvent to pour in down a chimney.
The utility model is achieved through the following technical solutions:
A solvent conveyer, it comprises the pipeline that connects solvent tank and workshop, filter, membrane pump and check valve have been linked in sequence on the pipeline from solvent tank to workshop.
The number of described check valve can be one, can be also two.
Compared with prior art, the utility model possesses following advantage:
The utility model has been set up check valve on the basis of original solvent conveyer, after check valve is arranged at membrane pump, can effectively avoid refluxing after the expansion of solvent heat, pours in down a chimney into described membrane pump, effectively protects membrane pump, extends its service life.
Accompanying drawing explanation
Fig. 1 is solvent conveyer structural representation of the present utility model.
The specific embodiment
The present embodiment provides a kind of duplicate protection system for Printing ink producing, and as shown in Figure 1, it comprises: connect the pipeline 1 in solvent tank and workshop, filter 2, membrane pump 3 and check valve 4 have been linked in sequence on the pipeline 1 from solvent tank to workshop.
Solvent streams in pipeline 1 is crossed after described membrane pump 3, even if heat expands, due to the existence of check valve 4, also can not pour in down a chimney into described membrane pump 3, facts have proved, has greatly extended the service life of membrane pump 3, greatly reduces cost.
Claims (2)
1. a solvent conveyer, is characterized in that: it comprises the pipeline that connects solvent tank and workshop, and filter, membrane pump and check valve have been linked in sequence on the pipeline from solvent tank to workshop.
2. solvent conveyer according to claim 1, is characterized in that: the number of described check valve is 1 or 2.
