Abstract
The utility model relates to an opening device for a lid body of a filter. The opening device for a lid body of a filter comprises a machine frame which is fixedly connected with a barrel body of a filter, and the machine frame is provided with a rotating shaft which is fixedly connected with one end of a connecting rod; the rotating shaft is fixedly connected with a supporting arm of the lid body of the filter; the other end of the connecting rod is hinged with one end of an elastic pressure extensible member; the other end of the elastic pressure extensible member is hinged with the machine frame. The utility model opens the lid body of the filter through the elastic force of an air spring, the balance control of the gravity of the lid body of the filter, and the transmission of the connecting rod and the rotating shaft, which is light and quick. The utility model can effectively reduce labor intensity and improve work efficiency.
Description
(1) technical field: the utility model relates to filter, relates in particular to the accessories apparatus of filter-press.
(2) background technology: filter-press comprises cylindrical shell and lid, installs filter core in the cylindrical shell.Be safe operation, cylindrical shell and lid are all made of steel material, and have certain thickness, so cylindrical shell and lid are all very heavy.When transposing filter core etc. needs opening cover, prior art is at vertical screw mandrel of the center of filter lid welding, screw mandrel and handwheel engagement, on the filter lid, weld the hollow cantilever of a upper end bending in addition, the telescopic supporting base of Weld-supporting cantilever on filter cylinder, described cantilever fit is installed in the supporting base, the curved end that hollow cantilever is inserted in the termination of the vertical screw mandrel of filter lid center welding.During opening cover, rotation hand wheel drives lid rising certain distance by screw mandrel, moves lid with hand push then, drives cantilever and rotates around supporting base, and lid separates with cylindrical shell, finishes the unlatching of lid.This opening device operation effort, time-consuming, labour intensity is big, inefficiency.
(3) summary of the invention: the purpose of this utility model provides the opening device of another kind of filter lid, and it opens filter lid light and fast.
Technical solutions of the utility model are as follows:
It comprises the frame of fixedlying connected with filter cylinder, install rotating shaft on the frame, rotating shaft is fixedlyed connected with connecting rod one end, and rotating shaft is fixedlyed connected with the supporting arm of filter lid, one end of the connecting rod other end and an elastic pressure extensible member is hinged, and the other end and the frame of elastic pressure extensible member are hinged.Described elastic pressure extensible member is an air spring, and device has spacer pin on frame.
The utility model relies on the elastic force of air spring and the control of strainer cover body weight equilibrium of forces and by the transmission of connecting rod and rotating shaft, opens the filter lid, and light and fast can effectively reduce labor intensity, and increases work efficiency.
(4) description of drawings:
Fig. 1 is a front view of the present utility model;
Fig. 2 is Figure 1A-A direction view, broken section, and Fig. 2 is different with Fig. 1 ratio.
(5) specific embodiment:
See Fig. 1, Fig. 2,1 is the shaped as frame frame, and it is welded to connect on the filter cartridge body wall.Install rotating shafts 4 by bearing to 9 on frame 1, an end of rotating shaft 4 centers and connecting rod 3 is welded to connect, and the supporting arm 6 of the two ends of rotating shaft 4 and filter lid 7 is welded to connect, and Fig. 2 illustrates supporting arm 6 and is both arms.
See Fig. 1, an end (cylinder block) of the other end of connecting rod 3 and air spring 2 is hinged, O
2Be its hinge.The other end of air spring 2 (piston rod) is hinged with frame 1, O
1Be its hinge, present embodiment adopts commercially available lifting type air spring.The also available existing commercial oil cylinder of air spring 2, metal spring or other elastic pressure extensible members substitute.
See Fig. 1, Fig. 2, returning apparatus has spacer pin 5 on frame 1, and excessive the reaching of restriction lid supporting arm 6 opening angles tumbled backward.
The course of work of the present utility model below is described:
See Fig. 1, W is the gravity of filter lid 7 among the figure, and 8 is the handle lobe of opening cover 7.By choosing air spring 2 with suitable elastic force, make lid 7 opening angle hour (for example≤15 °), lid gravity W slightly greater than spring 2 upward to elastic force, lid can not made progress because of spring force is excessive to bounce suddenly, when lid 7 (for example 〉=15 °) when opening angle is big, lid gravity be slightly less than air spring upward to elastic force, lid can not fallen down.
During opening cover 7, up mention handle lobe 8, see Fig. 2 with hand, the supporting arm 6 that is connected with lid 7 drives rotating shaft 4 and rotates, and connecting rod 3 rotates thereupon, and the piston rod of air spring 2 is protruding thereupon, drivening rod 3, rotating shaft 4 and supporting arm 6 rotate in the same way, lid 7 light fast openings.Because the elastic force and the lid gravity of air spring are in state in a basic balance, the strength that hand is used is very little can open the filter lid.With last identical reason, close also light and fast very of filter lid.
