Description

Detachable insulated casing

The invention relates to a pipe, in particular to a thermal insulation casing.

In order to process the liquid in the container, a large number of containers need to be applied directly to the liquid through the container wall, but the insertion should be sealed to prevent liquid loss. As with some agitator devices, it is necessary to penetrate the shaft through the bottom of the container, and the structure between the shaft and the wall of the container ensures that liquid in the container does not leak through the gap during rotation. A common method is to seal the gap with a heat-resistant and elastic material. However, the sealing material is also selected depending on the characteristics of the liquid to be treated or the pressure conditions of the container. The selection of the material is extremely difficult, and the selection of the material must be strictly prevented. The accident occurred. In the case of handling some high-risk liquids or pressure vessels, if constant temperature changes are involved, it is necessary to consider the shrinkage heat rise, so that the constantly changing temperature difference between the parts and the container is not easy to make on the container wall under long-term operation. There is a crack.

Especially in the dyeing machine for the dyeing and finishing industry, the main container is filled with a dye liquor which is high in temperature, high in pressure and contains complicated chemical components. In the dyeing process, heating and cooling of the dyeing liquid is an important part. It is necessary to rely on external steam or cooling water to be introduced into the pipeline inside the vessel, and adjust the temperature difference inside and outside the pipeline. The temperature of the dyeing solution. Moreover, the pipe also needs to be made of stainless steel, and it is required to allow the pipe to be removed from the container for maintenance. Because both the high-temperature steam and the cooling water use the same pipe, the gap between the pipe and the container will expand and contract due to the long temperature and strong temperature difference. The welding of the two welds is also difficult to withstand the long-term involvement, and eventually cracks will occur. And reduce machine life.

In order to solve the above problems, the object of the present invention is to provide a pipe which can be disassembled and at the same time can withstand a large temperature difference and pressure and has a sealing device, that is, a pipe which can penetrate the liquid container and is protected against Leakage device, and can overcome the long-term strong temperature difference and continuously expand and contract the damage caused by the weld at the intersection of the pipe and the container wall.

The solution to solve the technical problem of the present invention is to provide a detachable heat insulating sleeve for passing through the container casing, which comprises a pipe (1), an outer pipe (2), a cylinder (7) and an extrusion The component (6) is composed of a cylinder (7) fixed to the container casing, and the extrusion member (6) and the leakage preventing material (3) are placed between the pipe (1), the outer wall and the inner wall of the cylinder (7), and The tube (2) is sleeved outside the pipe (1) and connected concentrically with the pipe (1), and there is a cavity (5) between the outer pipe (2) and the pipe (1), and the pipe passes through the space inside the cylinder through the container case.

The invention provides a detachable heat insulating sleeve, wherein a rubber ring (4) is arranged between the extrusion member (6) and the outer tube (2), and at least one rubber ring (4A) is located at the extrusion member (6). On the outer wall, at least one apron (4B) Located on the inner wall of the extrusion, the apron (4A) seals the inner wall of the cylinder (7), and the apron (4B) seals the outer wall of the outer tube (2).

The invention provides a detachable thermal insulation sleeve, and a venting hole (13) is arranged under the cavity (5).

The invention provides a detachable heat insulating sleeve. The outer end of the pipe (1) outside the container casing is provided with an outer flange (8) and a snap ring (10), and the snap ring (10) is installed on the outer wall of the pipe (1). In the groove, the outer diameter of the snap ring (10) is larger than the inner diameter of the outer flange (8), and the outer flange (8) is rotatable concentrically with respect to the pipe (1).

The invention provides a detachable heat insulating sleeve, wherein the outer flange (8) and the lower flange (12) are connected by a screw (9), and the lower flange (12) is padded with the pipe (1). Piece (11).

When a removable pipe passes through the perforation of the container casing, there is a gap between the two for easy assembly and disassembly, but liquid can leak from the gap. The sealing method used in the present invention is achieved in the form of extrusion. The sealing method is to insert an elastic annular anti-leakage material into the gap between the pipe and the perforation, to fill the gap, fix it in the position, and then put it into the inner diameter of the leakage-proof material. The extrusion part and the inner and outer walls of the extrusion have a silicone sealing ring respectively contacting the outer wall of the outer tube and the inner wall of the cylinder to provide a layer of leakage protection for the leakage prevention material.

Since the pipe is removable, the extrusion and leak-proof material should also be removed. After repeated assembly and disassembly, the material should maintain a certain elasticity. When the leak-proof material is squeezed for a long time without being removed, its resilience is reduced. Once the surrounding parts are loose, the surface is eroded or even deformed, and the leakage-proof material is not If the gap is filled in time, there will be a leak. Especially for the design of the heat exchanger, the steam used for heating shares the same pipe as the cooled cold water. Therefore, the temperature changes of the fluid passing through the pipeline can vary greatly, and the deformation of the pipeline due to the temperature change is inevitable, so that the pipe diameter is expanded and contracted due to a sharp drop in the temperature of the fluid in the pipe, thereby causing a void. Even if the leak-proof material is elastic, there is still a chance of slight leakage before the gap is refilled.

In order to solve this problem, the present invention adopts a method of putting an outer tube around the pipe to replace the pipe wall with larger expansion as the pressing surface of the leakage preventing material. The outer tube is only concentrically connected to the pipe at the head and tail, so that the two are separated by a cavity. The cavity has a venting hole, so that the air in the cavity can be discharged through the vent hole when the pipe is heated and expanded, and the pressure in the space is balanced. Because there is no main contact surface between the pipe and the outer pipe, the heat energy is difficult to conduct from the pipe to the outer pipe; and the air in the space also indirectly absorbs the heat energy radiated from the pipe, and the heat energy that can be conducted to the outer pipe through the material or the air medium Therefore, the pressure is greatly reduced, so that the outer tube is not easily deformed to avoid liquid leakage.

In order to facilitate the connection of the pipe to the outer part at the end of the casing, the invention uses a flangeless connection without angle limitation. The pipe and the flange are welded together, and the other pipe to be connected is also connected by flanges of the same size. When one of the pipes needs to be bent, its angle is limited by the number of screw holes on the flange. In the design of the present invention, the flange at one end is not welded to the throat, so that the pipe on the other side can be relatively freely rotated without being limited by the flange fixing.

The invention is further illustrated by the following examples and Figures 1 - 7: Figure 1 is a front elevational view of the invention with the centerline to the right. The outer side of the cylinder 7 is connected to the container casing, and the inner side is hollow, and communicates inside and outside the container. A pipe 1 passes through the center of the cylinder through which the fluid passes through the vessel casing. An outer tube 2 is concentrically connected to the tube 1, the length of the outer tube 2 being substantially equal to the height of the cylinder 7, and in the operative position, the outer tube 2 connected to the tube 1 is placed in the hollow space of the cylinder 7.

Figure 2 is a perspective structure of the present invention. As shown in the figure, the pipe 1 and the outer pipe 2 are integrally connected with a space 5 therebetween. Below the space there is a venting opening 13 allowing free air in and out of the space.

At least one annular, resilient, leak-proof material 3 is placed between the outer wall of the outer tube and the inner wall of the cylinder. More than one configuration can be implemented in a stacked form, and Figure 1 shows four pieces of leak-proof material stacked in the above space.

The extrusion member 6 is a cylindrical member having an inner diameter slightly larger than the outer wall of the outer tube 2, usually not more than half a millimeter; and the outer diameter is also slightly smaller than the inner wall of the cylinder, and is also not more than half a millimeter. The inner and outer walls of the extrusion have pits for insertion into the leak-proof rubber ring 4. The leakage preventing rubber ring should respectively contact the outer wall of the outer tube and the inner wall of the cylinder when the pressing member is placed in the cylinder.

The extrusion member 6 is placed in the gap between the outer tube 2 and the cylinder 7 in the same manner as the leakage preventing material 3, and the bolt fixes the pressing member to the cylinder; the portion of the leakage preventing material which is protruded upward by the cylinder 7 In order to prevent the leakage-proof material from being pushed into the container casing belonging to the cylinder above the cylinder of Fig. 1. Together with the extrusion under the leak-proof material, the leak-proof material can be fixed at a specific position in the cylinder.

Figure 3 illustrates the three-dimensional appearance of the present invention in which the lower end of the conduit 1 utilizes a freely rotatable throat connection design. The outer flange 8 is not welded to the pipe 1, and the lower flange 12 is welded to the pipe connected below the pipe 1. The screw 9 is fixed to the outer wall of the pipe 1, at a position above the outer flange 8, and partially exposed outside the pipe 1 to restrict the outer flange from moving upward.

Figures 4 through 7 show the steps required to remove the throat on the side of the lower flange. Figure 4 shows that the bolts connecting the upper and lower flanges are loosened, and the lower flange 12 and the spacer 11 clamped between the lower flange and the pipe 1 are taken downward. The screw 9 is removed from the pipe 1. Without the limitation of screws and bolts, the outer flange 8 can move upwards, as shown in Figure 5. The snap ring 10 is a two semi-circular support member that is mounted in a recess in the outer wall of the pipe 1 such that the two snap rings project outwardly relative to the pipe. The outer diameter of the snap ring 10 is larger than the inner diameter of the outer flange 8, so that the outer flange cannot slide downward, and the outer flange 8 is connected to the lower flange 12 The point of stress when the time is reversed. The outer flange is sleeved between the screw on the outer wall of the pipe and the snap ring, so that the outer flange can rotate concentrically with respect to the pipe. After the outer flange is moved upwards, the two snap rings can be removed from both sides, and then the outer flange can slide out of the pipe 1.

After the parts of the external throat are removed in Fig. 5, the bolts connected between the extrusion and the cylinder 7 are loosened, and the extrusion is taken out from under the cylinder, followed by several layers of leakproof material.

Figure 6 is a schematic illustration of the extrusion 6 and the leakage preventing material 3 removed from the cylinder. The cylinder is connected to the container housing and is here fixed relative to the other parts.

When all the parts used to fix and squeeze the outer tube 2 and the pipe 1 are completely removed, the pipe can be taken out of the cylinder as shown in FIG.
