Abstract
The invention discloses an arc engaged screen plate mounting structure which comprises a first screen plate and a second screen plate, wherein filter screens are mounted on the first screen plate and the second screen plate by fasteners respectively, the first screen plate and the second screen plate are in hanging connection with a working chain and rotate around a working chain roller, and an lower screen plate cross beam of the first screen plate is engaged with an upper screen plate cross beam of the screen plate by an arc structure. The lower screen plate cross beam adopts a structure that a downward-bending structure is arranged at one end of the lower screen plate cross beam and connected with the filter screen by bolts, and a concave arc structure is arranged at the other end of the lower screen plate cross beam in a downward extending manner. The upper screen plate cross beam adopts a structure that a convex arc structure of an upward-bending structure engaged with the concave arc structure is arranged at one end of the upper second screen cross beam, and a downward-bending flange connected with the filter screen is arranged at the other end of the upper screen plate cross beam. A sealing clearance is formed between the concave arc structure and the convex arc structure. The mounting structure operates reliably and is low in cost.
Description
Technical field
The present invention relates to filter, the engagement type web plate mounting structure of especially a kind of circular arc.
Background technology
Rotary sieve is the filter plant that a kind of water source for natural environments such as rivers,lakes and seas filters and filtering accuracy is had relatively high expectations relatively.
When screen pack uses, screen pack is articulated on work chain by securing member, work chain moves on oval-shaped guide rail, be positioned at guide rail circular arc place, adjacent two screen packs are subject to the bending of guide rail shape and turn to, for ensureing not interfere between adjacent two blocks of web plates, between adjacent two screen packs, be all designed with certain gap, its mounting structure is as follows: as depicted in figs. 1 and 2, comprise the first web plate 101 and the second web plate 108, on described the first web plate 101 and the second web plate 108, by securing member, screen pack 102 is installed respectively, described the first web plate 101 and the second web plate 108 are mounted on respectively on work chain, be positioned at work chain roller 106 places, between the web plate entablature 107 of the web plate sill 103 of the first web plate 101 and the second web plate 108, leave gap, described gap location is provided with caulking gum 105, 105 one-tenth " Ω " shapes of described caulking gum, the two ends of described caulking gum 105 are fixed on the web plate sill 103 of the first web plate 101 and the web plate entablature 107 of the second web plate 108 by bolt 104 respectively.Caulking gum 105 effectively prevents from passing through the gap of rubbish between the first web plate 101 and the second web plate 108, and it is simple in structure, although sealing effectiveness is good, and long-term use, easily aging, need periodic replacement to safeguard, troublesome poeration, reduces production efficiency.
Summary of the invention
The applicant is easily aging for adopting caulking gum sealing in above-mentioned existing production technology, and service life is short, changes the shortcomings such as troublesome maintenance, a kind of reasonably engagement type web plate mounting structure of circular arc device is provided, thereby avoid use caulking gum, reduced costs, improved equipment operational reliability.
The technical solution adopted in the present invention is as follows:
The engagement type web plate mounting structure of a kind of circular arc, comprise the first web plate and the second web plate, on described the first web plate and the second web plate, by securing member, screen pack is installed respectively, described the first web plate and the second web plate are mounted on respectively on work chain, described the first web plate and the second web plate are respectively around the rotation of work chain roller, and the web plate sill of described the first web plate engages by arc structure with the web plate entablature of the second web plate;
The structure of described web plate sill is: described web plate sill one end is provided with downward bending structure, and described downward bending structure is connected with screen pack by bolt; The described web plate sill other end is provided with indent arc structure to downward-extension;
The structure of described web plate entablature is: described web plate entablature one end is provided with the evagination arc structure of the upwards bending structure engaging with indent arc structure, and its other end is provided with the flanging of the downward bending being connected with screen pack;
Between described indent arc structure and evagination arc structure, there is seal clearance.
Beneficial effect of the present invention is as follows:
The present invention is rational in infrastructure, install with easy to make, engage by arc structure by the web plate sill of the first web plate and the web plate entablature of the second web plate, and there is seal clearance between the two, avoid in prior art, needing to use the troublesome operations of caulking gum connection, two blocks of web plates of arc structure engagement have formed self sealing structure, and equipment dependability is good, and cost is low.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 3 and Figure 4, the engagement type web plate mounting structure of circular arc of the present embodiment, comprise the first web plate 101 and the second web plate 108, on the first web plate 101 and the second web plate 108, by securing member, screen pack 102 is installed respectively, the first web plate 101 and the second web plate 108 are mounted on respectively on work chain, the first web plate 101 and the second web plate 108 rotate around work chain roller 106 respectively, and the web plate sill 9 of the first web plate 101 engages by arc structure with the web plate entablature 11 of the second web plate 108;
The structure of web plate sill 9 is: web plate sill 9 one end are provided with downward bending structure, and downward bending structure is connected with screen pack 102 by bolt 104; Web plate sill 9 other ends are provided with indent arc structure 13 to downward-extension;
The structure of web plate entablature 11 is: web plate entablature 11 one end are provided with the evagination arc structure 12 of the upwards bending structure engaging with indent arc structure 13, and its other end is provided with the flanging of the downward bending being connected with screen pack 102;
Between indent arc structure 13 and evagination arc structure 12, there is seal clearance 10.
In actual use procedure, in the time that the first web plate 101 and the second web plate 108 rotate around work chain roller 106, no matter be how to rotate, the seal clearance 10 forming between indent arc structure 13 and evagination arc structure 12 in rotation process does not change; In addition, in the time having flushing water on rotary sieve, the water under natural fluidised form is can upwards not flow, and therefore, the rubbish on web plate also can upwards not flow along seal clearance 10, thereby rubbish can not flow through from seal clearance 10.The present invention both can meet the requirement of rotary sieve filtering accuracy, had saved again caulking gum material, economy, environmental protection, saved trouble, and had improved equipment reliability of operation.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of amendment.
