Description

Technical Field

[0001] The present application relates to a bag-pulling centrifuge, and in particular to a bag-pulling fixing structure of the bag-pulling centrifuge. Background Art

[0002] A Chinese patent document with application number 201710594138.2 discloses a filter bag installation structure for a bag-pulling centrifuge, which is provided with a plurality of stoppers matching the positions of the respective bag-pulling ribs near the liquid blocking ring on the drum wall, and the bag-pulling ribs pass through the corresponding stoppers, and the bag-pulling ribs are stressed, and the upper support serves as a force fulcrum, so that the bag-pulling forms a conical cylinder shape. Although this installation structure can make the installation of the bag-pulling easier, the stoppers are arranged on the inner wall of the drum, which is difficult to process. In fact, it is difficult to evenly arrange the 24 stoppers, which will cause the bag-pulling to fold together at the inclined part, affecting the subsequent work of the scraper.

[0011] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0012] Figure 1 The pull bag 10 shown in the figure comprises an annular filter element 11, an auxiliary material 12 arranged on the top of the filter element, and ribs uniformly distributed on the outer side of the annular filter element, the ribs extending upward to form an upper fixing member 13 with a lock hole.

[0013] Figure 4 The bag-pulling release machine shown in the figure comprises a rotary drum liner 20, a liquid blocking plate 30, a pull bag 10 and a mounting seat 40 arranged on the main shaft, wherein the liquid blocking plate is arranged on the top of the rotary drum liner. After the top and bottom ends of the pull bag are fixed respectively, the auxiliary material 12 is located below the liquid blocking plate 30, and the filter element 11 is unfolded into a cone shape. An extension arm 50 is arranged on the side of the mounting seat, and a slot is arranged in the extension arm. The lower fixing member 14 formed by the rib extending downward is installed in the slot through a fastener.

[0014] See also Figure 2 The liquid blocking plate 30 is provided with several through holes 31 adapted to the upper fixing member, the upper fixing member passes upward from the through holes, and the fastener 60 passes through the keyhole of the upper fixing member, and the fastener is inserted into the slot at the mouth of the liquid blocking plate to fix the upper fixing member. Figure 1 The auxiliary material is provided with a keyhole 15 adapted to the upper fixing piece, the auxiliary material is turned upward from the mouth of the liquid blocking plate, the upper fixing piece passes through the keyhole of the auxiliary material, and then the clamp, the card wire and other fasteners are inserted into the upper fixing piece. The keyhole provided on the auxiliary material is preferably a straight groove.

[0015] The end point of the sewing of the ribs and the filter element is located at the connection between the drum liner and the liquid blocking plate. The upper fixing part integrated with the ribs is located above the liquid blocking plate. The auxiliary material is close to the lower surface of the liquid blocking plate. The top of the pull bag is completely fixed, the unfolded shape of the pull bag is better, and the filtering effect is better.

[0016] See also Figure 3 Preferably, a notch 32 is provided at the edge of the liquid blocking plate 30, and a slot is formed between the notch and the drum liner. The slot is infinitely close to the drum liner, and the end point of the suture of the ribs and the filter element is almost close to the connection point between the liquid blocking plate and the drum liner, which will increase the upper support point of the pull bag and improve the stability of the pull bag installation.

[0017] Moreover, a notch is provided on the edge of the liquid blocking plate to construct a card slot, which makes processing easier.

[0018] Preferably, a non-slip protrusion is provided on one side of the slot opposite to the drum inner container, and the shape of the non-slip protrusion can be a non-slip part coated on the liquid blocking plate, such as rubber, or a protrusion feature processed on the liquid blocking plate. In this embodiment, a semicircular arc protrusion 33 processed on the liquid blocking plate is preferred.

[0019] The above is an explanation of the technical solution of the present application with exemplary preferred implementations. It should be noted that the above implementations are only used to illustrate the technical solution of the present application, rather than to limit it; although the present application is described in detail with reference to the above implementations, a person of ordinary skill in the art should understand that: it is still possible to modify the technical solution described in the above implementations, or to replace part or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of each implementation of the present application, and they should all be included in the scope of the claims and specification of the present application.
