[0031] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0032] like Figure 1-6As shown, the utility model provides a device for treating odor caused by high-temperature incineration of medical waste, comprising a semicircular filter box 1, a mounting base 2 and two semicircular filter screens 3. The semicircular surfaces on both sides of the semicircular filter box 1 are respectively provided with air inlets and outlets 101, and the smoke generated by incineration is introduced into one side, and after filtering, it is discharged from the other side. The top of the semicircular filter box 1 is a square end face and is provided with an opening 102. A limiting groove 103 connected to the opening 102 is provided on the inner side wall thereof. The limiting groove 103 is provided along the inner wall of the semicircular filter box 1 and is semi-circular in shape; the mounting base 2 is rotatably connected to the inner side of the opening 102. The depth of the opening 102 is equal to half of the width of the mounting base 2, and The length of the mounting base 2 differs from the length of the opening 102 by the width of a limiting groove 103, and therefore, there is a gap between the two ends of the mounting base 2 and the opening 102; the two semicircular filter screens 3 are respectively inserted at the top and bottom of the mounting base 2, and a convex edge 301 is provided on the outer side thereof, and a sealing strip is provided on the outer side of the convex edge 301 for sealing; the convex edge 301 on the lower semicircular filter screen 3 is inserted into the limiting groove 103 and closes the gap between the two ends of the limiting groove 103 and the opening 102; when the lower semicircular filter screen 3 is rotated by the mounting base 2, it can escape from the limiting groove 103, and then break away from its limit, and can move left and right.

[0033] It can be understood that the lower semicircular filter 3 is placed in the semicircular filter box 1 and is used as a filtering element to filter the smoke, while the upper semicircular filter 3 is in a standby state. When the lower semicircular filter 3 needs to be replaced, the installation base 2 is rotated to flip the positions of the two and replace them, thereby completing the replacement. Therefore, when replacement is required, it is only necessary to rotate the installation base 2 180 degrees to achieve the purpose of replacement. The semicircular filter 3 to be replaced is located outside the semicircular filter box 1 and can be easily disassembled, and the replacement process does not require interruption of smoke filtration.

[0034] Furthermore, in order to automatically replace the filter, two air pressure sensors are provided in the semicircular filter box 1. The two air pressure sensors are respectively located on both sides of the semicircular filter 3. The air pressure is detected by the air pressure sensor, and a controller is provided to determine whether blockage occurs according to the air pressure difference. According to the blockage situation, the rotation of the mounting base 2 is controlled and driven for automatic replacement.

[0035] It can be understood that the controller can control the air pressure sensor by conventional operating means of the prior art, which is the prior art and will not be elaborated on here. In addition, only a time switch can be set for control, and a replacement interval can be set. When the set usage time is reached, the rotation of the mounting base 2 is automatically controlled for automatic replacement.

[0036] In this embodiment, in order to prevent dust from being applied to the semicircular filter screen 3 to be replaced, a dust cover 4 is provided on the top of the semicircular filter box 1 to provide shielding and dust prevention.

[0037] Furthermore, in order to have multiple spare and replaceable filter screens, a lateral pushing mechanism 5 is provided on the dust cover 4, and a plurality of limit cards 501 are provided on the movable end of the lateral pushing mechanism 5, and the shape of the limit card 501 is an inverted U-shape, and the semicircular filter screen 3 is inserted in the U-shaped opening, and the upper semicircular filter screen 3 is inserted in one of the limit cards 501, and the other limit card 501 is inserted with a spare filter screen 6 identical to the semicircular filter screen 3, which is used to push the semicircular filter screen 3 and the spare filter screen 6 to move to the top of the mounting base 2 and move away from the top of the mounting base 2, and the semicircular filter screen 3 or the spare filter screen 6 to be used is moved to the top of the mounting base 2 by the lateral pushing mechanism 5 without blocking its rotation direction, and then, when the mounting base 2 rotates, the semicircular filter screen 3 or the spare filter screen 6 therein can be rotated into the semicircular filter box 1.

[0038] Among them, the mounting base 2 includes a base mounting bar 21, a rotating shaft 22 and a first motor 23. The output shaft of the first motor 23 is connected to the rotating shaft 22. The first motor 23 is installed on the semicircular filter box 1. The first motor 23 adopts a stepping motor and can control the rotation angle. The rotating shaft 22 is connected to the base mounting bar 21. Both sides of the base mounting bar 21 are provided with sealing layers for sealing. The top and bottom of the base mounting bar 21 are provided with transverse through positioning grooves 201. By rotating the base mounting bar 21 180 degrees, the upper and lower filters can be flipped and replaced to replace the filter.

[0039] In this embodiment, in order to replace and push the new filter screen onto the base mounting strip 21, a guide plate 7 is provided on the top of the semicircular filter box 1, and a guide groove 701 aligned with the positioning groove 201 is provided on the guide plate 7, and a slider 302 is provided on the flat side of the semicircular filter screen 3, and the slider 302 is slidably connected to the guide groove 701, and is used to guide the slider 302 to slide into the positioning groove 201 and slide out of the positioning groove 201, and the slider 302 slides in the guide groove 701 to guide, and the feeding distance of the lateral pushing mechanism 5 is set to a fixed value each time, that is, the pushing distance is constant each time, and each time it is pushed, the next filter screen is pushed into the positioning groove 201, that is, multiple limit cards 501 are equidistantly distributed.

[0040] In order to achieve controllable pushing distance, the lateral pushing mechanism 5 includes a guide rail 51, a second motor 52, a wire lever 53 and a movable block 54. The wire lever 53 is rotatably connected to the inner side of the guide rail 51. The second motor 52 is installed at one end of the guide rail 51, and the output shaft of the second motor 52 is connected to the wire lever 53. Several movable blocks 54 are all threadedly connected to the wire lever 53 and are respectively connected to the limit card 501 in a one-to-one correspondence. The wire lever 53 is driven to rotate by the second motor 52. Under the guidance of the guide rail 51, the movable block 54 performs lateral linear movement along the guide rail 51. The second motor 52 is a stepping motor.

[0041] It is understandable that if an automatic pushing action is required, after the controller controls the first motor 23 to drive the base mounting bar 21 and the rotating shaft 22 to rotate to replace the filter, the horizontal pushing action of the horizontal pushing mechanism 5 can be controlled.

[0042] In this embodiment, a dust box 8 is provided at the bottom of the semicircular filter box 1, and a through opening 801 connected to the semicircular filter box 1 is opened at the top of the dust box 8, and the filtered particles fall into the dust box 8 and are collected.

[0043] The specific working process of the utility model is as follows: the horizontal pushing mechanism 5 controls the limit card 501 to be completely separated from the dust cover 4, first insert a semicircular filter screen 3 on the top of the base mounting strip 21, and then rotate and install it into the semicircular filter box 1, and then install the semicircular filter screen 3 and the spare filter screen 6 in the empty limit card 501, and return it to the dust cover 4, and align one of the filter screens with the top of the base mounting strip 21; when replacement is needed, the first motor 23 drives the rotating shaft 22 and the base mounting strip 21 to rotate, and the upper and lower filter screens are replaced, and then the replaced filter screen is pushed out of the dust cover 4 from the mounting base 2 through the horizontal pushing mechanism 5, see Figure 4 And the next filter screen is positioned on the top of the base mounting strip 21, the replacement purpose can be achieved, and the next replacement is carried out according to the above principle until the spare filter screen 6 is used up.

[0044] The entire workflow is completed, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0045] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
