[0015] like Figure 1 and Figure 2As shown, this embodiment provides a new type of detachable locking mechanism based on a locking array filter. The array filter is designed based on the requirements of supporting consumables for ships, and the detachable locking mechanism ensures the simplicity and convenience of maintenance and the reliability of the product in use, including a locking column 1, a locking seat 2, and a key mechanism 3; the locking column 1 is a cylindrical part with a hollow cavity, wherein a buffer spring 11 is provided at one end of the locking column 1, and a release hoop 12 is provided at the step on the locking column 1, and hydraulic oil 13 is provided in the inner cavity feature at the other end of the locking column 1, and hydraulic plugs 14 are provided at the oil outlets on both sides of the hydraulic oil 13, wherein a rubber soft film 15 is also provided on one side of the hydraulic plug 14, and a bottom steel ball is provided on the outer side of the hydraulic plug 14;

[0016] The locking seat 2 includes a locking claw 21, and there are two locking claws 21, which form a closed O-ring structure with the middle steel ball of the locking column 1; one end of a single locking claw 21 is in squeezing contact with the bottom steel ball, and the other end is in squeezing contact with the middle steel ball, and at the same time, hydraulic pressure is used to form the force required for locking; the locking seat 2 also includes two horizontal and vertical supporting pillars, and a positioning hole is provided at the center of the horizontal pillar, wherein the locking column 1 is arranged in the positioning hole to form an axial hole assembly, and there are two longitudinal pillars, and a hinge point with the locking claw 21 is provided on the longitudinal pillar.

[0017] like Figure 3 As shown, the key mechanism 3 is an independent unit, and the key 31 included in the key mechanism 3 has an opening shape and size complementary to the slot on the locking column 1. The key mechanism 3 includes a power end and a transmission section, and the power end is provided with a gear set, a power input handle, and a power output rack 32, wherein one end of the power output rack 32 is connected to the key 31 through a connecting rod and a connecting plate group in the transmission section, wherein the connecting plate group includes two connecting plates, so the connecting plate and the key 31, the two connecting plates, and the connecting plate and the connecting rod are hinged to form a connecting rod mechanism.

[0018] In actual work, in the detachable locking mechanism described in this embodiment, the locking column 1 is installed at the bottom of the filter element. When the filter element is installed, the locking column is inserted into the locking seat 2. The bottom steel ball of the locking column 1 contacts the locking claw 21 on the locking seat 2 and is subjected to force. After the steel ball retracts, the force is transmitted to the upper steel ball through the rubber soft film 15 and the hydraulic plug to produce locking. When unlocking, just use the wrench-shaped key 31 to rotate the lower part of the locking column 1 to disengage it, and then adjust the disengagement hoop 12 to the position of the upper steel ball of the locking column 1, and the whole system can be unlocked. During maintenance, you can use Figure 3 The key mechanism shown is installed next to the locking mechanism to unlock the array filter element once.

[0019] The detachable locking mechanism of this embodiment solves the problem of insufficient reliability of the locking part of the filter element in the traditional array filter. At the same time, this embodiment can also effectively reduce the difficulty of filter maintenance. The entire device has a simple design and is easy to disassemble, replace and maintain. In actual use, it can effectively improve and ensure the reliability of the entire filter.
