[0002] The agitator is a device widely used in the papermaking industry, in order to keep the pulp in the pulp tank in a suspended state and uniform concentration in the circulating flow, the agitator should be equipped with a stuffing gland with reasonable structure. The stuffing gland is used for plugging the stuffing, and the stuffing is a structure arranged between the main shaft and the sealing seat to play a sealing role. The stuffing gland structure of the current agitator, as shown in Figure 1 and 2 , includes a pressing ring 1, a gland lug 2, a drain pipe 3, a gland lug 4, four parts are welded after assembly, and are processed by turning and drilling. This structure involves various raw materials and complicated processing process. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at providing a novel stuffing gland for agitator, and solves the technical problem of complicated manufacturing process.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0005] The stuffing gland for agitator is an integral casting part, and the stuffing gland includes a ring body, an ear part and a drain pipe. The drain pipe is arranged obliquely relative to one end surface of the ring body, and an anti-skid structure is arranged on the outer circumferential surface of the drain pipe.

[0006] Further, the anti-skid structure is a screw thread.

[0007] Further, the ear part has two parts and is arranged symmetrically about the ring body.

[0008] Further, the two ear parts are arranged symmetrically about the center line of the drain pipe.

[0009] Further, the ear part includes a connecting plate, and a C-shaped bolt groove is arranged at the end of the connecting plate.

[0010] Further, one end surface of the ear part in the thickness direction is coplanar with one end of the ring body, and the thickness of the ear part is less than the thickness of the ring body.

[0011] Further, the ring body is a circular ring body, and an annular cavity is arranged at the middle position in the thickness direction of the circular ring body. The inner diameter of the annular cavity is greater than the diameter of the through hole at both ends of the ring body.

[0012] The utility model has the advantages of:

[0013] The stuffing gland of the utility model is made by casting, is designed integrally, and is one part, so that the complicated processes such as welding and machining are omitted. The material of the stuffing gland is the same, and the problem of raw material selection is not involved.

[0014] The bolt groove on one side of the gland is changed to an open type, facilitating quick installation and dismounting in later use, and also facilitating casting. The drain pipe is changed to be inclined, facilitating mold drawing after casting. BRIEF DESCRIPTION OF DRAWINGS

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art belong to the scope of protection of the present application.

[0023] Embodiments of the present application:

[0024] As shown in Figures 3-4 , it is a structure schematic view of a filler gland for a stirrer. The filler gland is an integral type, which is a casting part, thereby omitting complicated processes such as welding and machining, and the material is the same, and there is no material selection problem.

[0025] The filler gland comprises a ring body 5, an ear 6 and a drain pipe 7. The ring body 5 is a circular ring body 5, both ends of which are through circular holes, and an annular cavity 51 is arranged at the middle position of the circular ring body 5 in the thickness direction, and the inner diameter of the annular cavity 51 is greater than the diameter of the through hole at both ends of the ring body 5.

[0026] ​​There are two ears 6, symmetrically arranged about the ring body 5. Each ear 6 includes a connecting plate, the end of which has a C-shaped bolt groove 61. One end face of the ear 6 in the thickness direction is coplanar with one end of the ring body 5; this coplanar end face is referred to as the right end face. The thickness of the ear 6 is less than the thickness of the ring body 5. The open bolt groove 61 facilitates quick installation and disassembly during later use, and also benefits casting (facilitating core setting and demolding).

[0027] The drain pipe 7 is inclined relative to the right end face of the ring 5, tilting to the right. This inclined design of the drain pipe 7 facilitates demolding after casting. The outer circumference of the drain pipe 7 is provided with an anti-slip structure 71, which is a pagoda thread, providing a more secure connection when connected to other soft water pipes. The anti-slip structure 71 can also be composed of multiple annular grooves along the length of the drain pipe 7. The two ears 6 are symmetrically arranged about the centerline of the drain pipe 7; this symmetrical structure facilitates the design of the casting mold.

[0028] After installation, the packing gland is used to abut the packing material at the left end of the ring 5, and the through hole in the middle allows the agitator spindle to pass through. The annular cavity 51 in the middle of the ring 5 has an inner diameter slightly larger than the diameter of the through holes at both ends of the ring 5. This facilitates installation and also creates a gap between the ring and the spindle, forming a water collection cavity that connects to the inner end of the drain pipe 7. During use, any slurry that seeps out can be collected and discharged through the drain pipe 7.
