[0035] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0036] A mounting device for a circular screen 5 comprises a mounting seat 1, a fixing device 2, a rotating part 3 and a pressing part 4.

[0037] The fixing device 2 is in abutment with the outer peripheral surface of the mounting seat 1, the rotating part 3 is arranged above the mounting seat 1 and is rotatably connected with the mounting seat 1, the clamping part 4 is nested in the end of the rotating part 3 away from the mounting seat 1, and the clamping part 4 makes a circular motion around the axis of the mounting seat 1, and the clamping part 4 is in abutment with the outer peripheral surface of the mounting seat 1; when installing the circular filter, by rotatably connecting the rotating part 3 with the mounting seat 1, when working, after the clamping part 4 is fixedly connected with the rotating part 3, the movement trajectory of the clamping part 4 is stabilized, so that it is more stable when pressing the edge of the filter, and the edge pressing action is more accurate, which reduces the difficulty of work and greatly reduces the requirements of the operator; the installation process of this circular screen 5 does not need to wait for the high-temperature round iron plate to cool down and then paste it manually. The temperature is too low, resulting in the folded circular screen 5 being unable to stretch naturally, losing the built-in tension, causing the problem of uneven installation of the circular screen 5. The installation device and method of the circular screen 5 can achieve the purpose of smooth installation of the screen, safe operation, and high replacement efficiency.

[0038] In one embodiment, the fixing device 2 includes a fixing seat 21 and at least two locking parts 22, and at least two locking parts 22 move on the fixing seat 21; the locking part 22 includes a clamping handle 221, a connecting rod 222 and an abutting part 223, and the clamping handle 221 and the abutting part 223 are arranged at both ends of the connecting rod 222; the abutting part 223 can be a nut, when it is necessary to fix the mounting seat 1, the clamping handle 221 is turned up, at this time, the connecting rod 222 drives the abutting part 223 to move forward and abut against the outer peripheral surface of the mounting seat 1, when the abutting part 223 abuts against the mounting seat 1, When the force of the seat 1 is not enough, the abutting part 223 can be rotated clockwise to fine-tune the abutting part 223 to deviate in the direction of the mounting seat. When the force of the abutting part 223 against the mounting seat 1 is too great, the abutting part 223 can be rotated counterclockwise to fine-tune the abutting part 223 to deviate in the direction away from the mounting seat 1 and adjust to a suitable abutting force. When the installation needs to be loosened, the clamping handle 221 is knocked down. At this time, the connecting rod 222 drives the abutting part 223 to retreat. The abutting part 223 can be fine-adjusted to abut against the fixed seat 21 to prevent the clamping handle 221 from shaking freely when not working.

[0039] In one embodiment, the rotating part 3 includes a shaft cap 31 and a connecting shaft 32, the shaft cap 31 is fixedly connected to the connecting shaft 32, a support block 11 and a central axis 12 fixedly connected to the support block 11 are provided at the bottom of the mounting seat 1, the support block 11 and the central axis 12 are coaxially matched, and the shaft cap 31 is detachably nested in the end of the central axis 12 away from the support block 11; the connecting shaft 32 and the central axis 12 form a 90-degree angle, the connecting shaft 32 rotates around the central axis 12 through the shaft cap 31, and the length of the connecting shaft 32 is greater than the radius of the mounting seat 1; the clamping part 4 includes a sleeve 41, the sleeve 41 is sleeved on the connecting shaft 32, and the clamping part 4 is slidably connected to the connecting shaft 32 through the sleeve 41; when the sleeve 41 is sleeved into the connecting shaft, the clamping part 4 can move on the connecting shaft 32, and the position of the clamping part 4 on the connecting shaft 32 can be adjusted according to the size of the mounting seat 1.

[0040] The clamping part 4 further includes a locking rod 46 . The shaft sleeve 41 is provided with a through hole 411 for the locking rod 46 to pass through. The locking rod 46 is threadedly connected to the through hole 411 . The locking rod 46 is used to lock the clamping part 4 on the connecting shaft 32 .

[0041] Among them, the clamping part 4 also includes a screw rod 42, a pressure wheel 43, an elastic member 44 and a tension member 45. The sleeve 41 is fixedly connected to the screw rod 42, and the pressure wheel 43, the elastic member 44 and the tension member 45 are sequentially mounted on the screw rod 42; one end of the elastic member 44 abuts against the pressure wheel 43, and the other end abuts against the tension member 45; the screw rod 42 forms an angle with the connecting shaft 32, and the angle is between 0°-30°. When the pressure wheel 43 is mounted on the screw rod, the edge of the pressure wheel 43 can squeeze the excess part of the edge of the circular screen 5 toward the mounting seat 1. The screw rod 42 is a threaded rod, the elastic member 44 is a spring, and the tension member 45 can be a nut. The tension member 45 can adjust the pressure of the pressure wheel 43 on the circular screen 5. When the pressure wheel 43 needs a greater pressure to press against the circular screen 5, the tension member 45 is screwed in the direction of the pressure wheel 43. At this time, the extrusion pressure of the tension member 45 on the elastic member 44 becomes greater, thereby increasing the force of the elastic member 44 on the pressure wheel 43; conversely, when the pressure of the pressure wheel 43 against the circular screen 5 is too great, the tension member 45 is screwed out in the direction away from the pressure wheel 43. At this time, the extrusion pressure of the tension member 45 on the elastic member 44 becomes smaller, thereby reducing the force of the elastic member 44 on the pressure wheel 43; therefore, when the installation device is in operation, the clamping portion and the clamping member can be doubly adjusted on the connecting shaft to obtain a force that is more suitable for the pressure wheel to press the circular screen.

[0042] In one embodiment, one end of the pressure wheel away from the elastic member is in abutment with the outer peripheral surface of the mounting seat.

[0043] A method for installing a circular screen 5 of the present invention is applicable to the installation device of the circular screen 5 mentioned above, and the method comprises the following steps:

[0044] S1. First, place the mounting seat 1 between the fixing devices 2, start the fixing device 2, and press against the outer peripheral surface of the mounting seat 1. Then, place the filter plate 6 and the circular screen 5 on the mounting seat 1 in sequence, cover with a high-temperature round iron plate and press tightly; turn up the clamping handle 221. At this time, the connecting rod 222 drives the abutting part 223 to move forward, and the abutting part 223 abuts against the outer peripheral surface of the mounting seat 1, thereby completing the fixing of the mounting seat;

[0045] S2. After the rotating part 3 is mounted on the mounting seat 1, the pressing part 4 is then nested on the rotating part 3, and the pressing part 4 is moved to a suitable position and then locked; the pressing part 4 slides on the connecting shaft 32 through the shaft sleeve 41, and when it slides to a specified position, the locking rod 46 is used to lock the pressing part 4 on the connecting shaft 32;

[0046] S3, after locking the pressing part 4, before the pressing part 4 rotates, pull the pressing wheel 43 in the direction away from the central axis 12, so that the pressing wheel 43 abuts against the circular screen 5, and then rotate the rotating part 3. At this time, the rotating part 3 drives the pressing wheel 43 with an inclined angle to make a circular motion along the mounting seat 1, and the screen is folded and fit with the filter plate 6;

[0047] S4. Finally, after placing the rubber strip 7 on the edges of the circular screen 5 and the filter plate 6 that are tightly attached, rotate the rotating part. At this time, the rotating part drives the pressing part to press the pressure strip to complete the installation of the rubber strip 7, and fix it with the clamp 8 to complete the installation of the circular screen 5.

[0048] In one embodiment, the diameter of the circular screen 5 is larger than the diameter of the filter plate 6 and the mounting seat 1; after the high-temperature round iron plate is covered, according to the principle of thermal expansion and contraction, the filter screen with the folded edges by the pressing part 4 is naturally stretched, and a certain tensile force is built in, so that the whole circle can be adjusted to be flat and wrinkle-free, and the neutral point of the screen is aligned without deviation.

[0049] For other contents of the installation device and method of a circular screen of the present invention, please refer to the prior art and will not be described in detail here.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form.
