Abstract
The utility model relates to a low resistance filtering device which is used for removing small amount of solid contents in liquids for oil refining industries, petroleum industries, chemical industries, medicine industries, food industries, light industries, etc. The utility model is composed of a main pipe, a branch pipe, a strainer component and a pressing cover. The middle part of the main pipe is communicated and welded with one end of the branch pipe, the other end of the branch pipe is welded with a flange edge, the strainer component is inserted in the branch pipe and a strainer groove on the wall of the main pipe from the opening end of the flange edge, the pressing cover is connected with the flange edge on the end of the branch pipe by screw bolts, and the strainer component is composed of a polyporous metal plate and a strainer which are connected into integration by spot welding and riveted connection. The utility model has the advantages of simple structure, labor saving, time saving, material saving, large filtering area, small resistance, etc.
Description
The utility model is the less filter of resistance of removing a small amount of solid content in the liquid for industrial departments such as oil refining, oil, chemical industry, medicine, food, light industrys.
Through the interrelated data retrieval, also there be not the lower resistance filter identical at present with the utility model structure.Remove a small amount of used filter of solid content in the liquid at industrial departments such as oil refining, oil, chemical industry, medicine, food, light industrys at present, it all is welded with the baffle plate that dams in being responsible for, make and be responsible for 35% of the sectional area baffle plate that dammed and block, and all filter with filter cylinder, its weak point is because of the baffle plate of damming and filter cylinder are arranged, so resistance is big, filter area is little, and complex structure, time-consuming feed consumption is many during manufacturing.
The purpose of this utility model provides a kind of simple in structure, and the saving of work and time feed consumption is few during manufacturing, the lower resistance filter that resistance is little.
The purpose of this utility model is achieved through the following technical solutions, the lower resistance filter is made up of the person in charge, arm, net-filter assembly and gland, the middle part of being responsible for communicates with an end of arm and connects with welding, the other end of arm is welded with flange, net-filter assembly is in the flange mouth end insertion arm and the filter screen groove on person in charge's tube wall of arm, gland links with the flange of bolt and arm pipe end, is used to push down net-filter assembly, make the net-filter assembly edge be responsible for wall and branch pipe wall near.Between gland and arm flange, be lined with gasket seal.Net-filter assembly is made up of expanded metal and filter screen, between expanded metal and filter screen with spot welding or be riveted into one.
The utility model with compare at the used filter of industrial departments such as oil refining, oil, chemical industry, medicine, food, light industry at present, have simple in structure and make saving of work and time to consume raw material few, the baffle plate resistance is little because of damming, thereby can improve flow and increase filter area.
Accompanying drawing is a structural representation of the present utility model, and Fig. 1 is the structural representation of y-type filter, and Fig. 2 is the structural representation of T type filter, and Fig. 3 is a reducing structure of filter schematic diagram, and Fig. 4 is that A in Fig. 1～3 is to enlarged drawing.
Below in conjunction with description of drawings operating position of the present utility model.In the accompanying drawing: 1-is responsible for; The 2-net-filter assembly; 3-filter screen groove; The 4-arm; The 5-gland; The 6-bolt; The 7-expanded metal; The 8-filter screen.Need filtered liquid to enter from the left end of the person in charge 1 shown in Fig. 1～3, the hole of the expanded metal 7 on net-filter assembly 2, the liquid that pass filter screen 8 back cleaning flow out from being responsible for 1 right-hand member, because net-filter assembly 2 is in the filter screen groove that is inserted on arm and the person in charge's tube wall, therefore can bear certain pressure, after using a period of time, after on the filter screen 8 fouling products having been arranged, can suspend and be responsible for flowing of liquid in 1, gland 5 is pulled down, extract net-filter assembly 2, net-filter assembly 2 is cleaned up, again the flange mouth of net-filter assembly 2 from arm 4 inserted in the filter screen groove 3, gland 5 is covered, tight a bolt and 6 can continue to make the liquid flows of being responsible in 1, make the utility model continue to come into operation.
Claims (2)
1, a kind of lower resistance filter, it is characterized in that forming by the person in charge, arm, net-filter assembly and gland, person in charge middle part communicates with an end of arm and connects with welding, the other end of arm is welded with flange, net-filter assembly is in the flange mouth end insertion arm and the filter screen groove on person in charge's tube wall of arm, and gland links with the flange of bolt and Zhi Guanduan.
2, by the described lower resistance filter of claim 1, it is characterized in that net-filter assembly is made up of expanded metal and filter screen, between expanded metal and filter screen with spot welding or be riveted into one.
