Detailed Implementation Manner

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0025] Please refer to Figures 1 to 5, in the present utility model: A bag filter for a pharmaceutical workshop, comprising a box body 1. The inner wall of the box body 1 is cylindrically arranged. Three air channels 2 and a waste discharge groove 3 are provided on the inner wall of the box body 1. A cleaning groove 4 is provided on the inner wall of the waste discharge groove 3. The shape of the cleaning groove 4 is L-shaped. A rotating cylinder 5 is rotatably connected to the inner wall of the box body 1. A first motor 6 is fixedly connected to the front surface of the box body 1. The output shaft of the first motor 6 is fixedly connected to the front surface of the rotating cylinder 5. Four through grooves 7 are provided on the outer side of the rotating cylinder 5. Filter bags 8 are fixedly connected to the inner walls of the two through grooves 7 located above and below. Two sets of four sliding grooves 9 are provided on the inner wall of the rotating cylinder 5. A sliding plate 10 is slidably connected between adjacent two sliding grooves 9. Two springs 22 are fixedly connected to one side of each of the two sliding plates 10. The other ends of the four springs 22 are respectively fixedly connected to the inner walls of the four sliding grooves 9. Slide rods 11 fixedly connected thereto are inserted through the two sliding plates 10. One ends of the two slide rods 11 are respectively fixedly connected to the two filter bags 8. A support rod 12 fixedly connected to the box body 1 is inserted through the back surface of the box body 1. One end of the front surface of the support rod 12 is inserted through the rotating cylinder 5 and rotatably connected thereto. A sealing block 13 is fixedly connected to one end of the front surface of the support rod 12. The outer side of the sealing block 13 is rotatably connected to the inner wall of the rotating cylinder 5. The shape of the sealing block 13 is semi-circular. The other ends of the two slide rods 11 are both in contact with the sealing block 13.

[0026] In the present utility model, during use, the air to be filtered enters the interior of the box body 1 from the air channel 2 at the top. The air will first enter the rotating cylinder 5 from the through groove 7 at the top. The sealing block 13 will seal the through groove 7 at the bottom. The air will pass through the top filter bag 8 and be discharged into the left and right air channels 2 through the two through grooves 7 and finally discharged into the pharmaceutical workshop, thereby achieving the effect of filtering the air in the pharmaceutical workshop. After long-term use, when a large amount of dust remains in the top filter bag 8 and needs to be cleaned, the user only needs to start the first motor 6 to drive the rotating cylinder 5 to rotate 180 degrees. At this time, the filter bag 8 at the bottom will move to correspond to the air channel 2 at the top, and thus replace the filter bag 8 filled with a large amount of dust to filter the air. During the rotation of the rotating cylinder 5, the slide rod 11 will slide along the outer side of the semi-circular sealing block 13. As the slide rod 11 slides, the slide rod 11 will drive the sliding plate 10 to slide along the inner wall of the sliding groove 9 until the slide rod 11 moves to the bottom of the sealing block 13. At this time, the filter bag 8 will be pushed by the slide rod 11 to turn its inner side to the outer side, and the dust in the filter bag 8 will fall into the waste discharge groove 3. The user can clean the dust separated from the filter bag 8 through the cleaning groove 4, thereby achieving the effect of discharging the dust in the filter bag 8. The user controls the first motor 6 to switch the positions of the two filter bags 8, always making one of the two filter bags 8 for filtering air and the other in the discharging state. By switching the positions of the two filter bags 8, the filter bags 8 can be replaced, so that the bag filter always maintains a good filtering effect and improves the practicability of the device.

[0027] Please refer to Figure 4 , wherein: One end of the sliding rod 11 is rotatably connected with a roller 14, and the outer side of the roller 14 is in contact with the sealing block 13.

[0028] In the present utility model, the setting of the roller 14 can reduce the friction force, improve the working smoothness of the device, and reduce wear to improve the service life of the device.

[0029] Please refer to Figure 3 , wherein: Two installation grooves 15 are opened on the inner wall of the waste discharge groove 3, and a second motor 16 is installed on the inner wall of each of the two installation grooves 15. Output shafts of the two second motors 16 are fixedly connected with two rubber rods 17.

[0030] In the present utility model, during the process of cleaning the filter bag 8 at the bottom, when the user turns on the second motor 16, it can drive the rubber rod 17 to rotate continuously in the installation groove 15. During the rotation of the rubber rod 17, it will pat the filter bag 8 to shake off the stubborn dust attached in the filter bag 8, thereby improving the cleaning effect of the dust in the filter bag 8.

[0031] Please refer to Figures 2 to 4 , wherein: A cavity 19 is opened on the sealing block 13, two air outlet grooves 20 are opened on the inner wall of the cavity 19, one end of the front surface of the support rod 12 is communicated with the cavity 19, and an air pump 21 is installed on the support rod 12.

[0032] In the present utility model, during the process of cleaning the filter bag 8 at the bottom, when the user turns on the air pump 21, the air pump 21 will inject air into the cavity 19 through the support rod 12. Then the air will be ejected from the two air outlet grooves 20, and the air will pass through the filter bag 8 in the reverse direction, thereby achieving the effect of backwashing and cleaning the filter bag 8, and further improving the cleaning effect of the filter bag 8.

[0033] Please refer to Figure 3 , wherein: A filter box 18 is inserted through the front surface of the box body 1 and is slidably connected thereto. The outer side of the filter box 18 is in contact with the inner wall of the waste discharge groove 3.

[0034] In the present utility model, the setting of the filter box 18 can filter the dust flushed back to avoid the situation of dust splashing. The user only needs to regularly pull out the filter box 18 to clean the dust filtered from the air.

[0035] The above is only the preferred specific embodiment of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent substitution or change, and should be covered by the protection scope of the present utility model.
