DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0034] See also Figure 1-5 As shown, it is the first embodiment of the utility model, which provides an online filter element replacement component for a circulating water pipeline, including a housing 1 and a branch component 2, and the branch component 2 includes a mounting pipe 201, a three-way joint 202, a main pipe 203, a branch pipe 204 and a solenoid valve 205.

[0035] Specifically, the installation pipe 201 passes through the outer walls of both sides of the shell 1 respectively, and the end of the installation pipe 201 away from the shell 1 is fixedly connected to the main pipe 203 and the branch pipe 204 through a three-way joint 202. The installation pipe 201 and the branch pipe 204 on one side of the shell 1 are both provided with a solenoid valve 205, and the installation pipe 201 on the other side of the shell 1 is rotatably connected with a pointer 207.

When the pointer 207 points to the bottom, it means that there is no circulating water flowing in the installation pipe 201. When the pointer 207 points to the left, it means that the circulating water in the installation pipe 201 flows from right to left. When the pointer 207 points to the right, it means that the surface flow direction is from left to right. The setting of the ring 208 is used to install between the rotating shaft 206 and the mounting plate 209, and the setting of the mounting plate 209 is used to drive the rotating shaft 206 to rotate;

The front and rear ends of the outer wall of the bidirectional screw rod 305 are threadedly sleeved with a first slider 304a, and the bottom of the first slider 304a movably passes through the top of the top cover 301 and is welded to the top of the arc block 304. The setting of the mounting seat 305a is used to install the bidirectional screw rod 305. The setting of the first slider 304a realizes that the rotation of the bidirectional screw rod 305 drives the arc block 304 to move toward or away from each other;

[0045] Both ends of the bidirectional screw rod 305 are provided with slots 305b, and the internal gap of the slots 305b is matched with an insert block 306a, and the end of the insert block 306a located outside the slot 305b is welded with a rotating rod 306, and the end of the rotating rod 306 away from the bidirectional screw rod 305 is welded with a knob 306b.

[0047] The rest of the structure is the same as that of the first embodiment.

[0048] The operation process of this embodiment is as follows: first, one end of the filter element body 303 is passed through the partition 302, and the other end of the filter element body 303 is located between the adjacent arc blocks 304, then the rotating rod 306 is clamped on the two-way screw rod 305 through the plug block 306a and the slot 305b, and the knob 306b is rotated. The knob 306b drives the two-way screw rod 305 to rotate synchronously through the rotating rod 306, and under the action of the threaded connection between the two-way screw rod 305 and the first slider 304a, the first slider 304a drives the arc block 304 to move, so that the arc block 304 is respectively clamped on the front and rear ends of the other side of the filter element body 303, and finally the top cover 301 is placed on the upper part of the interior of the shell 1, and the mounting rod 101 is passed through the connecting plate 301a, and the fastening nut 102 is threadedly sleeved on the mounting rod 101, thereby realizing the replacement of the filter element body 303.
