As preferably, the overall diameter of described position-limiting tube is the 85%-95% of filter core interior diameter.
As preferably, the overall diameter of described position-limiting tube is 90% of filter core interior diameter, and the overall diameter of position-limiting tube is slightly less than the filter core interior diameter, and Shi Du gap can guarantee the smooth installation of filter core between the two, can effectively must realize spacing purpose again.
As preferably, the outage of described adapter is shoulder hole, outage is divided into hole, taper hole and following hole, last hole, following hole are by the taper hole transition, outage is shoulder hole, has not only increased the outlet latus rectum, can satisfy the design requirement of the big flux of filtration system, and the inner structure of emptying can reduce material usage, the reduction product cost.
As preferably, at least one prominent rib is fixedly arranged on the outer wall of described adapter, have seal groove on the outer wall of described adapter, be with sealing ring in the seal groove, can make that the sealing property of adapter is better.
As preferably, described prominent rib has two, and is symmetrical arranged.
As preferably, column spinner is fixedly arranged at the top of described gland, is plugged with stubborn bar on the column spinner, twists the bar both sides and stretches out longlyer, is convenient to the operator and puts forth effort, and as rotary handle, can provide than high pulling torque, guarantees that annular tooth can effectively be pressed into the filter core end face, prevents from revealing.
As preferably, described feed liquor aperture is evenly arranged.
As preferably, the cross section of described annular tooth is triangle.
The beneficial effects of the utility model are: this product hermeticity can be good, long service life, and dismounting is more convenient, and design discharge is big.

Fig. 2 is the structural representation cutaway view under the utility model embodiment use state.
Fig. 3 is the structural representation of the utility model embodiment gland.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment: referring to Fig. 1-Fig. 3, the utility model embodiment comprises adapter 1, filter core 2, position-limiting tube 3, gland 4, column spinner 5 and stubborn bar 6.
Have outage 7 on the adapter 1 of this product, position-limiting tube 3 is fixedly connected on the outage 7 of adapter end face 11, the outer periphery of outage 7 is equipped with annular tooth 8 on the adapter end face 11, be covered with feed liquor aperture 9 on the position-limiting tube 3, and feed liquor aperture 9 arranges evenly, gland 4 is threaded with position-limiting tube 3, the outer periphery of gland bottom surface 10 is equipped with annular tooth 8, the cross section of annular tooth 8 is triangle, and filter core 2 is sleeved on outside the position-limiting tube 3, and filter core 2 is between adapter end face 11 and gland bottom surface 10.Be different from existing " face-face " seal form, this annular tooth 8 contacts with filter core 2 upper and lower end faces, compresses through gland 4 then, and the seal form by " line-face " more can guarantee sealing effectiveness, reduces the feed liquid disclosure risk.
The overall diameter of this product position-limiting tube 3 is slightly less than filter core 2 interior diameters, and the overall diameter of position-limiting tube 3 is the 85%-95% of filter core 2 interior diameters, is generally 90%, and Shi Du gap can guarantee the smooth installation of filter core 2 between the two, can effectively must realize spacing purpose again.
The outage 7 of this product adapter 1 is shoulder hole, outage 7 is divided into hole 12, taper hole 13 and following hole 14, last hole 12, following hole 14 are by taper hole 13 transition, outage 7 is shoulder hole, not only increased the outlet latus rectum, can satisfy the design requirement of the big flux of filtration system, and the inner structure of emptying can reduce material usage, the reduction product cost.
In order further to promote the sealing property of this product, the prominent rib 15 of two symmetries is fixedly arranged on the outer wall of adapter 1, have seal groove 16 on the outer wall of adapter 1, be with sealing ring 17 in the seal groove 16, and column spinner 5 is fixedly arranged at the top of gland 4, be plugged with on the column spinner 5 and twist bar 6, stubborn bar 6 both sides are stretched out longer, are convenient to the operator and put forth effort, as rotary handle, can provide than high pulling torque, guarantee that annular tooth 8 can effectively be pressed into filter core 2 end faces, prevent from revealing.
In the actual mechanical process: after correctly being installed on the filter plant by prominent rib 15 adapter 1 earlier, earlier the endoporus of filter core 2 is aimed at position-limiting tube 3, filter core 2 is inserted in position-limiting tube 3 to offset until the annular tooth 8 with adapter 1, adjust the position of filter core 2 until its center and adapter 1 center-aligned, after the lower surface of affirmation filter core 2 and annular tooth 8 fit tightly, before gland 4 is installed, for preventing that filter core 2 positions from changing again, when holding filter core 2 with hand gland 4 is threaded on the position-limiting tube 3, stubborn bar 6 end wherein that pinches on the gland 4 with the another hand slowly rotates then, when gland 4 rotates when offseting to annular tooth 8 and filter core 2 upper surfaces, slow with one's hands the unclamping slowly of holding filter core 2 before moved to the other end of twisting bar 6 subsequently, two hands catch stubborn bar 6 two ends firmly to rotate gland 4 till annular tooth 8 all is pressed into filter core 2 upper and lower end faces simultaneously, this moment, the whole erection process finished, because the improvement of dependency structure makes that the whole operation process is more simple and reliable in the utility model.
Above content described in this specification only is to the explanation of the utility model structure example.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
