Description

Technical Field

[0001] This utility model relates to the technical field of filter end cap removal tools, and is a tool for removing the end cap of a denitrification system membrane filter. Background Technology

[0002] Currently, RO reverse osmosis membranes are widely used in the denitrification process of chlor-alkali plants as the main equipment for removing sodium sulfate from brine. During long-term use, if the membrane module experiences internal leakage or a decline in membrane performance, the reverse osmosis membrane needs to be replaced. During the replacement process, the end caps at both ends of the module need to be opened to remove the module for replacement. Over time, leakage, salt accumulation, corrosion, or thermal expansion and contraction of equipment components between the end caps and the membrane module may occur, making it difficult to remove the end caps. In such cases, it is usually necessary to break the end caps for removal, which increases the operational risks and maintenance costs. Summary of the Invention

Detailed Implementation

[0016] This utility model is not limited to the following embodiments, and the specific implementation method can be determined according to the technical solution of this utility model and the actual situation.

[0017] In this utility model, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as front, back, top, bottom, left, right, etc. The positional relationships are determined based on the layout direction of the attached diagram in the instruction manual.

[0018] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0019] Example 1: As shown in the attached document Figure 1 , 2 As shown, the tool for removing the end cap 9 of the denitrification system membrane filter includes a base 1, a connecting rod 2, and a linear actuator 3. The connecting rod 2 is fixedly installed on the base 1, and a stop block 4 is fixedly installed on the upper part of the connecting rod 2. A linear actuator 3 is installed on the outside of the connecting rod 2, which can push the connecting rod 2 upward through the stop block 4.

[0020] When in use, connect the base 1 to the end cover 9. Then, the extended end of the linear actuator 3 extends upward and abuts against the stop block 4. The stop block 4 then pulls the connecting rod 2, the base 1 and the end cover 9 upward, thereby pulling the end cover 9 out of the outer sleeve 10 of the filter membrane cartridge. This is more labor-saving and safer and will not damage the end cover 9, thus reducing maintenance costs.

[0021] The tool for removing the end cap 9 of the denitrification system membrane filter can be further optimized and / or improved according to actual needs:

[0022] Example 2: As shown in the attached document Figure 1 , 2 As shown, connecting rod 2 is a screw, and stop block 4 is a nut threaded onto the screw. Using a screw and nut facilitates installation and makes it easy to replace the nut if it is damaged.

[0023] Example 3: As shown in the attached document Figure 1 , 2 As shown, a mounting post 5 is fixedly installed on the upper center of the base 1. The mounting post 5 has an upward-facing threaded hole in its center. The lower end of the mounting post 5 and the center of the base 1 have mounting holes 11. The screw rod is detachably installed to the base 1 through the threaded hole. The base 1 is connected to the screw rod by threads, allowing for disassembly and replacement of components and easy storage. The end cap 9 has a stud in its center. During installation, the stud is located in the mounting hole 11, allowing the base 1 to fit snugly against the end cap 9, facilitating the connection between the base 1 and the end cap 9.

[0024] Example 4: As shown in the appendix Figure 1 , 2 As shown, several reinforcing ribs 6 are provided between the mounting column 5 and the base 1. The reinforcing ribs 6 enhance the strength of the base 1, prevent damage caused by repeated stretching, and extend its service life.

[0025] Example 5: As shown in the attached document Figure 1 , 2 As shown, the base 1 has at least two threaded holes 7 that are vertically connected to the end cap 9 along its circumference near the outer side. The base 1 is connected to the threaded holes 7 on the end cap 9 by multiple bolts, which provides a stable connection and facilitates installation and disassembly.

[0026] Example 6: As shown in the appendix Figure 1 , 2 As shown, it also includes an outer sleeve 8. The outer sleeve 8 is fitted on the lower outer side of the connecting rod 2. A linear actuator 3 is installed on the upper end of the outer sleeve 8. The lower end of the outer sleeve 8 can abut against the outer sleeve outside the end cover 9. When the linear actuator 3 pushes the stop block 4, the lower end of the outer sleeve 8 can abut against the outer sleeve 10 of the membrane tube outside the end cover 9, so that the device has support and is more stable in use.

[0027] Example 7: As attached Figure 1 , 2 As shown, the linear actuator 3 is a hollow hydraulic jack, and the connecting rod 2 passes through the middle of the hollow hydraulic jack. By using a hollow hydraulic jack, the base 1 can move upward along the connecting rod 2. The connecting rod 2 can guide the movement, ensuring that the end cover 9 is subjected to uniform force and preventing damage.

[0028] The above technical features constitute various embodiments of this utility model, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
