Description

Feed processing equipment that is mounted on the inside of the pump sealing device structure}

The present invention relates to a sealing device, and more specifically, it is composed of a stator and a rotor, the rotor is configured to be coupled to each other separated when the ring (sealing surface) is worn when operating the processing equipment automatically due to the elastic member It is configured to be in close contact with the stator relates to a sealing device structure mounted inside the transfer pump of the processing equipment that can prevent the leakage of the fluid, as well as the sludge is introduced into the interior.

In general, a sealing device is installed between the housing and the shaft of a fixing part including a compressor, a water pump, a turbine, an engine, and a shaft propulsion shaft to prevent leakage of liquid therein. A pair of ring mechanical seals are installed in surface contact with each other.

Such a dreaming device is provided with a sealing device so that the internal fluid between the rotating shaft in the pump and the stopping box does not leak to the outside due to the pressure generated inside the pump. One or more oil seals made of elastomers, which are typically elastomers, are installed. Three or four grand gland packings are bundled in sets. However, in the case of oil seal or gland packing, it has a surface contact structure that comes into close contact with the surface of the rotating shaft and the outer wall of the boxing box. When the clamping pressure is applied to prevent the load, the load is applied to the rotating shaft, leading to breakage of the rotating shaft.

Due to these problems, conventionally, oil seals and grand packing are evaluated as one-off products, but mechanical seals have springs that compensate for wear of the sliding surface and prevent the leakage from occurring by opening the sliding surface to the pressure inside the pump. However, many problems have been raised in use.

In the case of the oil seal described above, the lip of the inner diameter presses the surface of the rotating shaft to prevent leakage, and it is impossible to use it at high pressure. Even if oil seal is replaced, it is impossible to prevent leakage due to damaged shaft surface.

In the case of the gland packing, a grease or teflon is added to the fibrous surface to reduce the friction, and thus the inside of the starting box is filled in three or more layers, but the surface of the rotating shaft and the outer wall of the boxing box are adopted. It has the structure to seal the fluid leaked through the same time and if the force for surface contact is applied for sealing, the load of the rotating shaft is applied, which causes a significant loss of the rotating force or damages the surface of the rotating shaft at the same time as the packing damage due to frictional heat. It is not possible to expect a complete seal and is limited to devices that allow some leakage.

In addition, in the case of a coil spring equipped with a single strand, the structure is mounted on the outside of the rotating part so as to be locked in the fluid and rotates. However, during high-speed rotation, the spring protruding from the outside of the rotating part decreases or bends in the direction of rotation of the rotating shaft, and if the reverse rotation occurs, the shape change of the spring's winding structure is released. Leakage occurs because it is unable to maintain normal surface contact or compensate for sliding of the sliding part by detaching from the surface connection part of the rotating shaft.

Looking at the prior art first, the publication No. 10-2005-0096371 (specific) relates to a sealing device of the rotating shaft, the rotating side face ring fixedly coupled to the rotating shaft rotatably installed in the housing, and corresponding to the rotating side face ring A fixed side face ring rotatably coupled to the rotating shaft, an elastic member for elastically deflecting the fixed side face ring to the rotating side face ring side, and the rotating side face ring and the fixed side to prevent leakage. It is configured to include a groove formed in at least one sealing surface of the sealing surface of the face ring.

The prior art described above seals the rotating side face ring and the fixed side face ring, but forms an elastic member between the fixed side face ring and the housing so that the elastic member is fixed to the face side ring when the abutting portions are worn. It is to press the to the side of the rotating face ring, but when the solid slurry or other foreign matter is introduced into the transfer pump there is a problem that the elastic member is affected to maintain a stable airtight to play a role of sealing. .

A rotary housing which is fastened and provided with a spring and a bellows, and a rotor face which is fastened to one side of the rotary housing and has a perturbation surface, wherein the seal face is rotated in conjunction with the motor shaft. The rotating force is transmitted by the rotary housing.

The above-described prior art mainly describes that the bellows is made of a material which does not tear even under high temperature, high pressure conditions or a large size, and has excellent heat resistance. It is composed of a material having excellent heat resistance, but has a problem that it is difficult to continuously use because it is composed of a structure in which the slurry generated in the fluid can flow.

The present invention has been made in order to solve the above problems of the prior art, the shape of the connecting portion of the rotating part and the shaft in the packing of the elastic member or the elastomer material of the rotating part even under high-speed rotation, reverse rotation, high pressure conditions, Although the solid slurry flows into the transfer pump, it has been developed as a technical problem with the focus on providing a product that is made of a box-shaped shape that is not affected by foreign matters or solid slurry in the fluid to maintain stable airtightness. .

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

1 to 3 has a ring shape and is configured at one end of the housing (h) inside the transfer pump, and a packing 11 for absorbing shock is formed on the outer circumference thereof and in a lateral direction corresponding to the rotating part 20. The fixed part sliding surface 12 is interpolated and protrudes outward. The fixing part 10 is generally mounted at one end of a conventional housing (h), the hollow portion is configured so that the shaft (s) can be penetrated therein, and the outer circumference is formed in multiple stages to be rotated (20) And protrude to the other side corresponding thereto. Here, the fixed part sliding surface 12 interpolated on one side of the fixed part 10 corresponds to the rotating part sliding surface 24 of the rotating part 20 to be described below and is configured to be in contact with each other.

The rotary part 20 is a core component of the present invention, and is configured in a structure that is coupled and disassembled in the form of a box as shown in FIGS. 2 to 5, and the space portion to allow the shaft (s) to penetrate therein. The upper clutch 21 and the lower clutch 22 are formed. The upper clutch 21 has a packing 23 for absorbing shock therein, and a rotation part sliding surface 24 interpolating and protruding in a lateral direction corresponding to the fixing part 10 and the upper clutch 21. The elastic member 25 is configured between the lower clutch 22 and the fixed part sliding surface due to the elastic member 25 when the fixing part 10 and the rotating part 20 are mounted inside the transfer pump. Compensating the wear of the 12 and the rotary sliding surface (24), that is, it is composed of a structure capable of protecting the elastic member 25 formed therein and continuous surface contact.

In the case of the upper clutch 21, as shown in Figs. 3 to 5, a space portion is formed therein, and the shaft s is configured to penetrate the space portion, and a lower side of the lower clutch 22 to be described below. Insertion groove (n) is configured so that the protrusion (t) is fitted to be coupled. In the present invention, the interpolation groove (n) is shown in two, but if necessary, the number can also be configured and used.

As shown in FIGS. 3 to 5, the lower clutch 22 includes a protrusion t on which an upper end portion of the upper clutch 21 is fitted to insert the interpolation groove n of the upper clutch 21. It is configured to fit, wherein the protrusion (t) is also used to selectively configure the number as necessary, the upper, lower clutches 21, 22 are the number of the interpolation groove (n) and the protrusion (t). Should be configured identically to each other.

In addition, the material of the fixing part 10 and the rotating part 20 is composed of tungsten carbide, silicon carbide, carbon is configured to be used continuously for a long time.

As described above, the elastic member 25, which is fitted between the upper and lower clutches 21 and 22, has a fixed part sliding surface 12 and a rotating part of the fixing part 10 as illustrated in FIG. 3 or 4. While the rotating part 20 rotates with the shaft s in the state where the rotating part sliding surface 24 makes surface contact, wear of the fixed part sliding surface 12 or the rotating part sliding surface 24 is reduced. When the wear occurs naturally, when the gap naturally occurs, the upper clutch 21 is pushed toward the fixing part 10 by the elastic force of the elastic member 25 and the gap generated due to the wear is automatically generated. Will be able to compensate.

Conventionally, techniques using elastic force have been developed, but there has been a technique for compensating abrasion by using elastic force because it is configured to easily expose the outside of the sealing device, that is, the elastic member, but the slurry formed inside the transfer pump The gap between the elastic members does not fulfill their purpose, and the elastic member shrinks and rotates during forward rotation, and the structure leaks out and collapses during reverse rotation. There was a problem that proper sealing is not made.

In the present invention, however, the upper and lower clutches 21 and 22 are configured between the slurry formed in the transfer pump so as not to penetrate primarily, and the fixed part and the rotary part sliding surfaces 12 and 24 of the present invention. When the abrasion occurs when the slurry penetrates between the upper and lower clutches 21 and 22, the slurry may escape between the pitches of the elastic members 25 formed by the centrifugal force of the conveying fluid.

That is, the elastic member 25 does not damage the packing of the elastomer material by the centripetal force generated inside the transfer pump even if the solid slurry generated during the workpiece processing is in contact with the cutting oil and the cooling water to flow into the transfer pump. Even if the rotational direction of the shaft s is changed in the forward or reverse direction, the elastic member 25 is not loosened or wound.

Here, the elastic member 25 is pushed the upper, lower clutches 21 and 22, but the reason that only the upper clutch 21 can flow is the outer clutch of the lower clutch 22 as shown in Figs. A plurality of set screws 26 are configured on one side of the circumference to allow the lower clutch 22 to be fixed to the shaft s. The set screw 26 may be selectively configured in plurality, as needed, and the set screw 26 is configured to have an inclination of 90 ° or 120 ° so that the lower clutch (S) on the surface of the shaft (s) 22) is to be configured to be in close contact with the inner diameter.

The sealing device 100 of the present invention of this form is the packing 23, the elastic member 25 is configured in the interior of the fixing portion 20 when the upper clutch 21 and the lower clutch 22 is engaged when assembled The packing 23 and the elastic member 25, which are configured to be sealed in the form of a box in which the inflow of the slurry in the fluid into the fixing part 20, are not included in the external direction such as the rotation direction of the fluid and the shaft s. Maintaining a state of seating fixed inside the sealed fixing portion 10 does not cause a change in shape by a factor.

In addition, unlike the conventional sealing device that fixed the rotating part 20 by the elastic force of the elastic member 25 and offset the reaction force, the upper and lower clutches 21 and 22 of the thick rotating part 20 are interlocked like gears to transmit rotational force. The elastic member 25 as shown in FIG. 6 or 7 because there is no pressure applied to the elastic member 25 and the rotational force of the shaft s is transmitted only to the rotating part 20. Since only serves to compensate for the wear of each of the fixed part sliding surface 12 and the rotating part sliding surface 24 is to ensure stability in operation.

According to the sealing device structure mounted inside the transfer pump of the processing equipment according to the present invention, when the fixed part sliding surface 12 of the fixed part 10 and the rotating part sliding surface 24 of the rotating part 20 are in contact with each other, The whole device 100 can be started with one component, and in particular, the rotating part 20 is divided into upper and lower clutches 21 and 22, and when the shaft 100 is mounted on the shaft s, the rotational force is the elastic member 25. Attenuating in the rotating part 20, and can support the rotational force instead of the rotating part 20, and according to the rotation direction of the shaft (s) transmitted to the rotating part 20 of the transfer pump, respectively, the fixed part sliding surface 12 and the rotating part sliding surface (24) By automatically compensating the wear and tear of the elastic member 25, the phenomenon of bending or deformation of the elastic member 25 is fundamentally prevented, and even if vibration or shock is applied, even if the phenomenon occurs, the phenomenon of the packing inside the rotating part 20 is prevented and stable. Can perform sealing function Simple assembly and disassembly in the form of a box is a useful invention that confers convenience.
