Description

Quick operation method and mechanism of hose inflation pressure sealing device

The invention relates to a quick operation method and its mechanism for the intersection section of the two ends of the hose used in the inflation and expansion pressure sealing device of the hose.

The invention belongs to static sealing technology.

In order to prevent the leakage of gas or other liquid media, a hose inflation pressure sealing device can be used at the joint between the sealing film and the rigid container. A sealing groove is provided along the interface of the rigid container (the cross-section is generally isosceles trapezoidal or U-shaped, and the upper mouth is retracted), and the sealing groove extends along the edge of the container interface to form a closed sealing groove. When performing the sealing operation, first cover the sealing film on the sealing groove, and then place the hose on the side of the sealing film that is not in contact with the sealing groove, that is, place the sealing film between the hose and the sealing groove , and then press the hose into the sealing groove (the sealing film is between the hose and the inner wall of the sealing groove, and is also pressed into the sealing groove), then, fill the hose with a certain pressure of gas, use The pressure generated by the expansion of the hose wall makes the sealing film and the inner wall of the sealing groove close to each other, so as to realize the sealing connection between the sealing film and the rigid container. During the unsealing operation, first deflate the hose in the sealing groove, and then take the hose out of the sealing groove. At the intersection of the two ends of the hose, in order to ensure the sealing effect, it is necessary to press a section of the inflation and deflation end of the hose and a section of the closed end of the hose together (sealing operation) or take it out (unsealing operation) of the same section of the sealing groove. The operation process is time-consuming and labor-intensive, and is not suitable for frequent sealing and unsealing operations of the sealing device.

The purpose of the present invention is to provide a simple and reliable method and mechanism suitable for frequent operation of the sealing device.

The method of the present invention is characterized in that: before the intersection of the two ends of the hose is pressed into or taken out of the sealing groove, the space for the intersection of the two ends of the hose is increased to facilitate the pressing of the intersection of the two ends of the hose. Or take out the operation of the sealing groove.

The mechanism for implementing the method of the present invention is characterized in that: there is a gap in the sealing groove at the intersection of the two ends of the hose, and a movable block is installed at the gap, and the movable block can move outwards and inwards respectively relative to the sealing groove, Before the intersection section at both ends of the hose is pressed into or taken out of the sealing groove, the movable block moves outward, so that the space formed by the sealing side of the movable block and the inner wall of the sealing groove to accommodate the intersection section at both ends of the hose and the sealing film increases. big.

Advantages and positive effects of the present invention: adopting the present invention, the sealing and unsealing operation of the expansion pressure sealing device of the hose can be easily performed, which saves time, effort and reliability.

Example:

The MCT bioreactor for the production of biogas and organic fertilizers by dry fermentation is composed of a reinforced concrete tank with an open top and end face, a sealing film and a hose inflation pressure sealing device, etc. The reactor is sometimes sealed for anaerobic fermentation and sometimes opened Aerobic fermentation, anaerobic, aerobic conversion is more frequent. The inflation and pressure sealing device of the hose adopts the fast operation method and its mechanism of the present invention at the intersection section of the two ends of the hose.

Fig. 1 is a three-dimensional schematic diagram of the quick-operating mechanism used for the intersection section at both ends of the hose in this embodiment;

Fig. 2 is the three-dimensional schematic diagram of side guide plate;

Figure 3 is a three-dimensional schematic diagram of the movable block.

As shown in Figure 1, the sealing groove 9 at the intersection of the two ends 7-1 and 7-2 of the hose 7 is cut off a side to form a gap, and the sealing side 5-2 of the movable block 5 (see Figure 3 ) has the same size and shape as the inner wall of the truncated side of the sealing groove 9. By means of a driving mechanism, the movable block 5 can move outwards or inwards relative to the sealing groove 9, so that before the hose 7 is pressed in or taken out, the intersection sections 7-1 and 7-2 at both ends of the hose 7 and the seal are accommodated. The space of the membrane 8 is increased, so as to achieve the purpose of convenient sealing and unsealing operations; in addition, the movable block can also be fixed at the sealing position, so that after the hose is inflated and expanded, the sealing membrane 8 is closely attached to the inner wall of the sealing groove 9 On, to achieve a reliable seal.

As shown in FIG. 1 , the base 1 is fixed on the straight part of the interface of the rigid container 10 to form the support of the quick operation mechanism. Described driving mechanism comprises: the side guide plate 2 and screw seat 4 that are fixed on the base 1, the nut 6 that is fixed on the movable block 5, the screw mandrel 3 that is threadedly connected with screw seat 4 and nut 6, wherein The screw seat 4 supports the screw 3 and limits the axial movement of the screw 3; by turning the screw 3, the movable block 5 with the guide tail 5-1 can be moved along the upper guide groove 2 of the side guide plate 2 The direction of -1 moves outward (relaxation) or inward (compression) relative to the sealing groove 9;

Specific steps:

When performing the sealing operation, after placing the sealing film 8 between the sealing groove 9 and the hose 7, press the non-end intersection section of the hose into the sealing groove 9, and then rotate the screw rod 3 counterclockwise to make Movable block 5 moves outward (relaxes), and the space that accommodates flexible pipe 7 two ends 7-1, 7-1 intersecting section and sealing film 8 increases, and the two ends 7-1, 7-2 of flexible pipe 7 can be easily The intersecting sections are pressed into the sealing groove together, and the screw mandrel 3 is rotated clockwise to make the movable block 5 move inward (compressed), when the sealing side 5-2 of the movable block is smooth with the inner wall of the sealing groove 9 on the rigid container 10 When they are connected together to form a sealing cross-section consistent with the sealing groove 9, the rotation of the screw rod is stopped. At this time, the self-locking effect of the screw rod 3 and the screw nut 6 keeps the movable block 5 from loosening and remains in the sealing position. Location. Inflate the hose 7 through the inflation and deflation end 7-1 of the hose, so that the sealing film 8 can be closely attached to the inner wall of the sealing groove, and a rapid airtight seal between the sealing film 8 and the rigid container 10 can be realized.

When performing the unsealing operation, the hose 7 is deflated first, and then the screw rod 3 is rotated counterclockwise to move the movable block 5 outward to accommodate the intersection sections 7-1 and 7-2 at both ends of the hose 7 and the sealing film The space of 8 increases, and flexible pipe 7 (comprising two ends intersecting section) can be taken out from sealing groove 9 conveniently, promptly unseals between sealing film 8 and rigid container 10.
