Technical Field

[0001] The utility model relates to the technical field of separators, in particular to a pressure-bearing quick-release membrane separator. Background Art

[0002] The working principle of the pervaporation membrane separator (hereinafter referred to as membrane device) is to separate the permeable components from the non-permeable components through the pervaporation membrane (hereinafter referred to as membrane) under a certain temperature and pressure. In order to maintain a certain chemical potential difference between the upstream and downstream sides of the membrane, the upstream side of the membrane is usually under a certain pressure, and the downstream side of the membrane is vacuumed, so that the permeable components pass through the membrane surface from the upstream side of the membrane to the downstream side of the membrane.

[0003] In industrial applications, since the membrane device needs to withstand a certain pressure, it is usually designed with reference to a shell-and-tube heat exchanger. Tube sheets are fixed at both ends of the membrane device cylinder, and the flanges on the heads at both ends of the membrane device are fixed to the tube sheets of the membrane device cylinder by bolts. However, since the life of the membrane tubes in the membrane device is limited, the heads at both ends of the membrane device need to be disassembled regularly to replace the membrane tubes. The existing membrane device heads are difficult to disassemble, and there is also a risk of bolts rusting. Utility Model Content

[0030] See also Figure 1 - Figure 5 A pressure-bearing quick-release membrane separator comprises: a cylinder 1, a blind cover 2 and a locking component 3. The blind cover 2 is arranged at the end of the cylinder 1 and is connected to the cylinder 1 through a rotating bracket 21. The rotating bracket 21 supports the blind cover 2 to rotate. This is a prior art and will not be described again. Two blind covers 2 are provided, corresponding to the two ends of the cylinder 1 respectively. The difference between the two blind covers 2 is that one of the blind covers 2 has a vacuum port. A raised ring 11 is fixedly connected to the end of the cylinder 1.

[0031] The locking component 3 is arranged between the end of the cylinder 1 and the blind plate cover 2. The blind plate cover 2 blocks the port of the cylinder 1 through the locking component 3. The locking component 3 includes a locking rod 31. A locking groove 12 for inserting the locking rod is opened on the end of the cylinder 1. The locking groove 12 is opened on the raised ring 11. After closing the blind plate cover 2, the blind plate cover 2 is locked by cooperating with the locking rod 31 and the locking groove 12.

[0032] The locking rod 31 includes a threaded section 311 and a smooth section 312. The diameter of the smooth section 312 is larger than the diameter of the threaded section 311. The locking groove 12 includes an entry section 121 corresponding to the threaded section 311 and a locking section 122 adapted to the smooth section 312. The entry section 121 facilitates the entry of the threaded section 311, and then the locking rod 31 is rotated to allow the smooth section 312 to enter the locking section 122.

[0033] The blind cover 2 is fixedly connected to a connecting block 32, which is provided with a through slot 321. A rotating block 33 is rotatably connected to the through slot 321. The rotating block 33 is threadedly connected to the threaded section 311, which passes through the rotating block 33. After the blind cover 2 is closed, the locking rod 31 is rotated so that the threaded section 311 enters the entry section 121. Then, the locking rod 31 is rotated so that the threaded section 311 leaks out of the rotating block 33 and enters the through slot 321. Then, the smooth section 312 enters the locking section 122. At this time, the axis is perpendicular to the axis of the blind cover 2, preventing the blind cover 2 from opening suddenly under pressure. When the blind cover 2 is difficult to open, the locking rod 31 is perpendicular to the blind cover 2, and then the locking rod 31 is rotated so that the threaded section 311 abuts the raised ring 11, thereby removing the blind cover 2.

[0034] The locking component 3 also includes a guide block 34, a movable extrusion block 35 is provided on the raised ring 11, and an inclined surface 36 is provided on the guide block 34 and the extrusion block 35, and the two inclined surfaces 36 are in contact. A guide block 34 is provided on the upper and lower parts of the connecting block 32, and the guide block 34 and the connecting block 32 are integrally formed. A sliding rod 37 is slidably connected to the raised ring 11, one end of the sliding rod 37 is fixed to the guide block 34, and the other end is fixedly connected to the push plate 38, and a spring 39 is sleeved on the sliding rod 37, and the two ends of the spring 39 are respectively connected to the push plate 38 and the raised ring 11, and a coaxial push plate 313 is fixed on the smooth section 312, and the push plate 38 extends toward the locking rod 31 and extends into the range of the push plate 313.

[0035] When in use, first close the blind cover 2, then the locking rod 31 drives the rotating block 33 to rotate, so that the threaded section 311 enters the entry section 121, and the locking rod drives the rotating block 33 to rotate. After the threaded section 311 enters, the locking rod 31 is rotated, and the threaded section 311 rotates on the rotating block 33, so that the smooth section 312 moves, and finally enters the locking section 122. During the movement of the smooth section 312, it drives the push plate 313 to move. The push plate 313 first abuts the push plate 38, and then pushes the push plate 38 to move. The push plate 38 moves with the rod body, and the rod body moves with the extrusion block 35. During this process, the spring 39 is compressed, and finally the two inclined surfaces 36 contact, and the inclined surface 36 on the extrusion block 35 squeezes the guide block 34, further stabilizing the blind cover 2.
