Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] like Figure 1 This is a schematic diagram of the structure of this utility model, a split spinneret for ultrafiltration membrane fibers, including a spinneret 1 and a spinneret head 2, as shown. Figure 2 As shown, the bottom surface of the spinneret 1 has a mounting groove 11 corresponding to the spinneret 2. The spinneret 2 is installed in its corresponding mounting groove 11. The spinneret 2 and the spinneret 1 are fixed together by a locking assembly 3. The number of spinnerets 2 can be one, two or more. This application does not make a specific limit on the number of spinnerets 2.

[0021] like Figure 2 , 3 As shown in Figure 4, the locking assembly 3 makes the spinneret 2 detachable. The locking assembly 3 includes a locking block 31, a movable block 32, an elastic element 33, and a locking groove 21 that matches the locking block 31. The spinneret 1 has a receiving groove 15 that communicates with the mounting groove 11. The movable block 32 is slidably arranged in the receiving groove 15. The locking block 31 and the movable block 32 are fixedly connected. The locking groove 21 is opened on the spinneret 2. The elastic element 33 is arranged in the receiving groove 15. One end of the elastic element 33 abuts against the movable block 32, and the other end abuts against the spinneret 1. Through the design of the locking assembly 3, the spinneret and the spinneret can be installed in a separate structure. The spinneret can be disassembled and installed separately, which is convenient for replacement and has low maintenance cost. The elastic element 33 can be a steel leaf spring, a helical spring, a torsion bar spring, a rubber spring, etc.

[0022] When the spinneret 2 is positioned in the mounting groove 11, the locking block 31 is engaged in the locking groove 21.

[0023] like Figure 3 , 4 As shown, the bottom surface of the locking block 31 has an inlet surface 311 that tapers from top to bottom toward the movable block 32, which makes it easier for the spinneret 2 to push aside the movable block 32 and the locking block 31, so that the locking block 31 can enter the locking groove 21.

[0024] like Figure 3 , 4 As shown, the bottom surface of the movable block 32 is provided with a groove 321, which makes it easier for the user to use a tool to move the movable block 32 so that the locking block 31 can be disengaged from the locking groove 21 and the locking of the spinneret 2 can be released.

[0025] like Figure 3As shown, a guide rod 322 protrudes from the end of the movable block 32 away from the spinneret 2. A guide groove 12 is provided on the spinneret 1 for the guide rod 322 to move. The guide groove 12 is connected to the receiving groove 15. The guide rod 322 is slidably arranged in the guide groove 12. Through the design of the guide groove 12 and the guide rod 322, the movement stability of the movable block 32 can be increased.

[0026] The spinneret 1 has a limiting groove 13 for accommodating the elastic element 33. The limiting groove 13 is connected to the accommodating groove 15. The end of the elastic element 33 is located in the limiting groove 13. The limiting groove 13 can increase the stability of the elastic element 33 and prevent the elastic element 33 from failing.

[0027] A positioning block 22 protrudes from the outer wall of the spinneret 2. A positioning groove 14 communicating with the mounting groove 11 is provided on the spinneret 1. The positioning groove 14 includes a connecting section 141 and a positioning section 142. The connecting section 141 spirals upward along the inner wall of the mounting groove 11, and the positioning section 142 extends circumferentially along the mounting groove 11. The connecting section 141 and the positioning section 142 are connected. The positioning block 22 moves along the connecting section 141 and enters the positioning section 142. Through the cooperation of the positioning block 22 and the positioning groove 14, the connection stability between the spinneret 2 and the spinneret 1 can be further increased. The positioning block 22 and the positioning groove 14 can also further enhance the locking degree of the spinneret 2 with the cooperation of the locking component 3. The positioning block 22 is located above the locking groove 21.

[0028] In use, the spinneret 2 is aligned with the mounting groove 11. The positioning block 22 on the spinneret 2 enters the connecting section 141 in the positioning groove 14 and moves along it until the positioning block 22 enters the positioning section 142. At this time, the spinneret 2 pushes the locking block 31 aside. The elastic element 33 contracts and has elastic potential energy, rotating around the circumference of the spinneret 2, causing the positioning block 22 to move along the positioning section 142 until it reaches the end of the positioning section 142. At this time, the locking groove 21 is aligned with the locking block 31 and enters the locking groove 21 under the action of the elastic force of the elastic element 33, completing the installation and locking of the spinneret 2. The locking assembly 3 can complete the circumferential and axial fixation of the spinneret 2. The mounting groove 11 completes the radial fixation of the spinneret 2. The positioning groove 14 can fix the radial and axial fixation of the spinneret 2. The locking assembly 3 can assist the positioning groove 14 and the positioning block 22 in completing the circumferential fixation.

[0029] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
