DETAILED DESCRIPTION

[0015] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0016] Example:

[0017] The accompanying drawings show a specific implementation of a flat-rotating quick-opening bag filter of the utility model, as shown in FIG. Figure 1 It mainly includes a tank body 1 and a top cover 2. An inlet A is arranged on the top of the tank body 1 and an outlet B is arranged on the bottom, and a side-in and bottom-out design is adopted.

[0018] The bottom of the top cover 2 is provided with a receiving groove 2a, in which a sealing disc 3 is provided, and a guide rod 9 is connected to the sealing disc 3, which passes through the top cover 2 and extends to the outside. The sealing disc 3 is connected to the top cover 2 through a positioning assembly 4, which includes two through holes 4a provided at the upper end of the guide rod 9, a positioning insert 4c provided on one side of the guide rod 9 and connected to the top cover 2, and a positioning pin 4b inserted in the through hole 4a and the positioning insert 4c for positioning the sealing disc 3.

[0019] A circle of limiting groove 1a is opened on the inner wall of the tank body 1, and a movable sealing ring 5 is installed in the limiting groove 1a through a first spring 1b. The movable sealing ring 5 is sealed with the sealing disk 3 under the action of the first spring 1b, and the sealing disk 3 can be positioned and fixed by a positioning component 4.

[0020] A rotating frame 6 is provided on one side of the tank body 1, a rotating column 10 is provided on the rotating frame 6, one end of the top cover 2 is rotatably connected to the rotating column 10, a second spring 11 is provided between the rotating column 10 and the top cover 2, and the top cover 2 can move up and down a certain distance and can rotate.

[0021] The other side of the tank body 1 is provided with a locking mechanism 7, which includes a screw 7b rotatably connected to the side support 7a and a rotating head 7c threadedly connected to the screw 7b. The other end of the top cover 2 is provided with a locking seat 8 that cooperates with the locking mechanism 7, and the locking seat 8 is provided with an opening 8a. After the screw 7b is rotated into the opening 8a, the rotating head 7c can be rotated to achieve a locking connection with the locking seat 8.

[0022] After the locking mechanism 7 is opened and disengaged from the locking seat 8, the top cover 2 can bounce upward and separate from the can body 1, thereby realizing the rotation opening of the cover.

[0023] In this embodiment, sealing gaskets are provided on the sealing disk 3 and the movable sealing ring 5 to improve the overall sealing effect.

[0024] When the embodiment is working, the initial sealing state of the filter is as follows: Figure 1 As shown, when the top cover 2 is opened, the positioning pin 4b is first pulled out, and the sealing disk 3 is lifted upward under the action of the first spring 1b and the movable sealing ring 5, and automatically retracted into the accommodating groove 2a. At this time, a through hole 4a below is exposed, and the positioning pin 4b is aligned with it and inserted and further inserted into the positioning insert 4c, so that the sealing disk 3 is positioned and fixed. Figure 2 Then, the rotating head 7c is screwed to move upward along the screw 7b, so that the rotating head 7c is separated from the locking seat 8, and then the rotating head 7c and the screw 7b are rotated out from the opening 8a to separate the top cover 2 from the tank body 1. At this time, under the joint action of the second spring 11, the movable sealing ring 5, and the first spring 1b, the top cover 2 is automatically lifted to the top of the tank body 1, and the cover can be opened by rotating. At this time, the movable sealing ring 5 rises until its top surface is flush with the top surface of the tank body 1, as shown in FIG. Figure 3 shown.
