Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment: Fig. 1 is a kind of just middle-efficient filtering bag disclosed by the utility model, including rectangular outer frame, rectangular outer frame by
Two cross bars 1 parallel to each other and two vertical poles 2 parallel to each other are constituted.Rectangular outer frame is equipped with several points parallel to each other
Spacer bar 3, partition rod 3 is parallel with vertical pole 2, and the both ends of partition rod 3 are connect with two cross bars 1 respectively.
As shown in Figure 3, Figure 4, cross bar 1 is equipped with sliding slot 1a towards the side in rectangular outer frame, and sliding slot 1a is along the length side of cross bar 1
To setting, the both ends of partition rod 3 are inserted in sliding slot 1a.The both ends (inserting in the part in sliding slot 1a) of partition rod 3 are quadrangular
Shape cooperates with sliding slot 1a inner wall shape, and the both ends of partition rod 3 and sliding slot 1a inner wall have biggish stiction, pushes hard
Pulling spacer bar 3 just can be such that partition rod 3 moves along the length direction of sliding slot 1a.
As shown in Figure 1, rectangular outer frame is equipped with the filter cloth 4 of two pieces of rectangles, dotted line is the line of demarcation of two blocks of filter clothes 4 in Fig. 1.
As shown in fig. 6,4 two sides of filter cloth are integrally formed several pieces of cloth 4a, the identical several separations of quantity are all connected on two blocks of filter clothes 4
Bar 3(is shown in Fig. 4), the filter cloth 4 between adjacent partition rod 3 surrounds filter bag 41, and adjacent two pieces of pieces of cloth 4a of the same side are located on filter cloth 4
The both ends of seamless connection (suture or glued) rear enclosed filter bag 41.
As shown in figure 3, there is gap of leaking out at the top of pieces of cloth 4a between cross bar 1 after two pieces of adjacent pieces of cloth 4a are seamless, because
Compression bar 5(compression bar 5 is pressed with bolt 6 on this cross bar 1 and cross bar 1 is pressed between the nut and nut of bolt 6), the top pieces of cloth 4a
Portion is attached on cross bar 1 by the compression of compression bar 5, can effectively prevent leaking out.
As shown in Figure 3 (also in combination with Fig. 4 and Fig. 5), the length direction of partition rod 3 is equipped with the first long through-hole 3a, filter cloth 4
It is through in the first long through-hole 3a.As shown, being equipped with the second long through-hole 2a, the second long through-hole on two 2 length directions of vertical pole
The both ends of 2a are communicated with sliding slot 1a.In conjunction with Fig. 1 and figure, one end of filter cloth 4 is inserted in the first long through-hole 3a of partition rod 3, filter cloth 4
The other end insert in the second long through-hole 2a of vertical pole 2.Adjacent point of two of two pieces of 4 joints of filter cloth (in Fig. 1 at dotted line)
Spacer bar 3 is connected by bolt 6, and the nut and nut of bolt 6 clamp two partition rods 3, can prevent two pieces of 4 joint of filter cloth leakages
Gas.As shown in figure 5, partition rod 3 is in addition to both ends are quadrangular shape, rest part is triangular prism shape, i.e., cross section is triangle
Shape, and the tip of triangle is upward, is designed in this way the windage that can reduce partition rod 3.
As shown in Figure 1, shown in Figure 5, several jack 1b are equipped on cross bar 1 evenly and at intervals along its length, jack 1b is passed to
In sliding slot 1a, and the both ends of partition rod 3 are equipped with pin hole 3b, jack 1b and pin hole 3b and are connect by bolt, can be incited somebody to action using bolt
Partition rod 3 is fixed on the specified location of sliding slot 1a, extract 3 side of partition rod after bolt can 1a along the chute length direction it is mobile,
So as to adjust the position of partition rod 3.
The implementation principle of the present embodiment are as follows: two blocks of filter clothes 4 are set in rectangular outer frame, and every block of filter cloth 4 is enclosed with partition rod 3
At several filter bags 41, the both ends of filter bag 41 are sutured with pieces of cloth 4a.Several partition rods that will be connected on one of filter cloth 4 when use
3 are pushed into one end of rectangular outer frame, this block filter cloth 4 is made to be contracted to minimum, and another block of filter cloth 4 is extended to maximum and is used to filter sky
Gas.When extending to maximum 4 service life of filter cloth termination, which is contracted to the other end of rectangular outer frame, by another piece
Filter cloth 4 stretching, extension and for filtering air.Due to successively using two blocks of filter clothes 4 for filtering air, service life be it is common just
Twice of middle-efficient filtering bag, so substantially increasing service life.
Adjust 4 stretching, extensions of filter cloth/contraction state method: the bolt on all partition rods 3 is taken out, by compression bar 5 from cross bar 1
On remove, then all partition rods 3 that the filter cloth 4 stretched originally connects are allocated to one end of rectangular outer frame, by what is shunk originally
Filter cloth 4 stretches, and then fixes 3 position of partition rod bolt insertion partition rod 3, then pushed up the pieces of cloth 4a on filter cloth 4 with compression bar 5
Portion is pressed on cross bar 1.
The method for removing filter cloth 4: compression bar 5 is removed from cross bar 1, cuts off the two panels pieces of cloth of 4 two sides of filter cloth seamless connection
Then 4a extracts filter cloth 4 out out of vertical pole 2 the second long through-hole 2a.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
