[0005] Preferably, the lower support plate is provided with a plurality of supporting holes whose diameters are smaller than the diameter of the bag-type inner liner, and the bottom of the bag-type inner liner is in an arc-shaped structure.

[0006] Preferably, a limiting hole cooperating with the barrel cover is provided on the top of the filter bag pressing plate.

[0007] Preferably, the filter bag pressing plate, the middle reinforcing plate and the lower supporting plate have the same diameter and are all in contact with the inner wall of the filter barrel.

[0008] Preferably, the edges of the middle reinforcement plate and the lower support plate are both provided with a plurality of waist-shaped fixing holes.

[0009] Compared with the prior art, the utility model has the following advantages: the bag-type inner liner fixing structure of the filter machine of the present invention supports and fixes the top, middle and bottom of several bag-type inner liner respectively through the filter bag pressing plate, the middle reinforcing plate and the lower supporting plate, which can effectively prevent the bag-type inner liner from expanding and squeezing out when under pressure. The structure is simple, the cost is low and it is easy to assemble. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The utility model will be further described below in conjunction with the accompanying drawings.

[0015] like Figure 1 As shown, a bag inner liner 4 fixing structure of a filter machine includes a filter bag pressing plate 1, an intermediate reinforcement plate 2, a lower support plate 3 and a plurality of bag inner liners 4, wherein the filter bag pressing plate 1 is covered on the top of the plurality of bag inner liners 4, and the filter bag pressing plate 1 is provided with a plurality of through holes 5 which are arranged one by one corresponding to the plurality of bag inner liners 4, the intermediate reinforcement plate 2 is simultaneously sleeved on the middle of the plurality of bag inner liners 4, and the lower support plate 3 is supported on the bottom of the plurality of bag inner liners 4.

[0016] The present invention provides a bag-type inner liner 4 fixing structure for a filter, which supports and fixes the top, middle and bottom of a plurality of bag-type inner liner 4 respectively through a filter bag pressing plate 1, a middle reinforcing plate 2 and a lower supporting plate 3, and can effectively prevent the bag-type inner liner 4 from expanding and squeezing out when subjected to pressure. The structure is simple, the cost is low, and it is easy to assemble.

[0017] Preferably, the lower support plate 3 is provided with a plurality of supporting holes 6 whose diameter is smaller than that of the bag-type liner 4, and the bottom of the bag-type liner 4 is in an arc-shaped structure. The supporting holes 6 cooperate with the arc-shaped structure to limit and fix the bottom of the bag-type liner 4, and the bag-type liner 4 can be directly placed.

[0018] Preferably, the top of the filter bag pressing plate 1 is provided with a limiting hole 7 that cooperates with the barrel cover. Because the filter bag pressing plate 1 needs to be removed before inserting and removing the bag-type liner 4, the filter bag pressing plate 1 can be limited and fixed by only cooperating with the limiting column on the barrel cover through the limiting hole 7, which is convenient for operation.

[0019] Preferably, the filter bag pressing plate 1, the middle reinforcing plate 2 and the lower supporting plate 3 have the same diameter and are all fixedly connected to the inner wall of the filter barrel.

[0020] Preferably, the edges of the middle reinforcement plate 2 and the lower support plate 3 are provided with a plurality of waist-shaped fixing holes 8. The middle reinforcement plate 2 and the lower support plate 3 are fixedly connected to the inner wall of the filter barrel through the waist-shaped fixing holes 8, respectively, and the fixing effect is very good.

[0021] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
