Description

Technical Field

[0001] The present invention relates to the technical field of impurity removal devices, and in particular to an impurity removal device for the production of ultrafine tea powder. Background Art

[0002] The tea is pulverized into tea powder with a mesh size of over 600 by the instantaneous pulverization method, maximizing the retention of the original natural green color, nutrients, and pharmacological components of the tea leaves, without any chemical additives. There are two types of ultrafine tea powder: pure tea and blended tea. After the ultrafine tea powder is produced, it still needs to be screened for impurity removal, evenly piled and packaged, and large particle impurities such as tea slices that are not completely pulverized in the ultrafine tea powder are removed. However, after the vibration screening device is used for a long time, blockage and other situations will occur, affecting the subsequent screening efficiency and screening effect of the ultrafine tea powder. It also requires the staff to manually clean the filtering device after a long shutdown, reducing the production efficiency of the ultrafine tea powder, increasing the risk of microbial contamination, and increasing the labor burden of the staff. Summary of the Invention

[0003] The present invention discloses an impurity removal device for the production of ultrafine tea powder, which solves the problems that after the screening device is used for a long time, blockage will occur, affecting the subsequent screening efficiency and screening effect of the tea powder, and the staff also needs to manually clean the filtering device.

[0004] To solve the above technical problems, the present invention specifically adopts the following technical solutions:

[0005] An impurity removal device for the production of ultrafine tea powder, comprising a box body, a cylindrical barrel with one open side is rotatably connected inside the box body, a filter frame is detachably connected to the outer ring surface of the cylindrical barrel, a sealing plate is fixed inside the box body and is rotatably connected to the open side of the cylindrical barrel, a fixing ring is fixed on the sealing plate and is located inside the cylindrical barrel, a feeding pipe is fixedly connected through the sealing plate, and the discharging end and the feeding end of the feeding pipe respectively penetrate the bottom of the fixing ring and one side of the box body; collecting frames in contact with the inner wall of the cylindrical barrel are fixed on both sides of the fixing ring, and a slag discharge pipe penetrating the box body is communicated with the collecting frames.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] When the filtering frame is directly below the cylinder, after the tea powder is conveyed into the cylinder through the feeding pipe, the tea powder can enter the filtering frame. Then, the cylinder is repeatedly rotated slightly so that the tea powder in the filtering frame moves repeatedly, and then the tea powder falls downward through the filter holes on the filtering frame. The filtered tea powder is discharged through the discharge port at the bottom of the box body. When it is necessary to clean the impurities accumulated in the filtering frame, after the cylinder rotates, the filtering frame is located at the top of the cylinder, and the impurities in the filtering frame can fall downward into the cylinder and then be blocked by the fixing ring. Subsequently, they slide down along the outer ring surface of the fixing ring into the two collection frames and are then discharged through the slag discharge pipe. The present invention can quickly and automatically clean the impurities accumulated in the filtering frame, without the need for long-term shutdown for manual cleaning, improving the screening efficiency and screening effect of the tea powder and reducing the labor burden of the staff.

[0015] The following will describe the specific content of the present invention in detail with reference to the drawings and embodiments.

[0016] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the present invention provides a impurity removing device for producing ultrafine tea powder, including a box body 1. A cylinder 2 with one open side is rotatably connected inside the box body 1. A filter frame 3 is detachably connected to the outer ring surface of the cylinder 2. A circular plate 4 fixedly connected to the open side of the cylinder 2 is fixed inside the box body 1. A fixing ring 41 located inside the cylinder 2 is fixed on the circular plate 4. A feeding pipe 42 fixedly connected is penetrated through the circular plate 4. The discharging end and the feeding end of the feeding pipe 42 respectively penetrate through the bottom of the fixing ring 41 and one side of the box body 1. Collection frames 43 in contact with the inner wall of the cylinder 2 are fixed on both sides of the fixing ring 41. A slag discharging pipe 44 penetrating through the box body 1 is communicated with the collection frames 43. After the filter frame 3 is located at the bottom of the cylinder 2, the tea powder is conveyed into the cylinder 2 through the feeding pipe 42. The tea powder can then fall into the filter frame 3 and then drop downward after passing through the filter holes on the filter frame 3, so that the tea powder is discharged through the discharging port at the bottom of the box body 1 to complete the screening of the tea powder. When the screening of the tea powder is completed, the cylinder 2 can be rotated to make the filter frame 3 located at the top of the cylinder 2. The impurities accumulated in the filter frame 3 can then fall downward, enter the cylinder 2 and be blocked by the fixing ring 41, and then slide down to the two collection frames 43 respectively through the outer ring surface of the fixing ring 41. The slag discharging pipe 44 is communicated with an external exhaust fan, and the impurities in the collection frames 43 can be extracted to complete the automatic cleaning of the impurities in the filter frame 3. An annular sliding groove is opened at one end of the cylinder 2 close to the open part, and an annular sliding block adapted to the sliding groove is fixed on the circular plate 4 box.

[0017] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the side of the filter box 3 moving in the clockwise direction is open. A sealing plate 31 that blocks the open area is fixed inside the filter box 3. A perforated plate 32 located inside the filter box 3 is attached to the sealing plate 31. The diameter of the perforations on the perforated plate 32 is smaller than the diameter of the filter holes on the filter box 3. Insertion rods 33 inserted into the perforations on the perforated plate 32 are fixed on the sealing plate 31; a fixing plate 34 located outside the filter box 3 is fixed on the sealing plate 31. A spring 35 that passes through the sealing plate 31 and is connected to the perforated plate 32 is fixed on the inner side of the fixing plate 34. A push rod 36 that passes through the fixing plate 34 is fixed on the perforated plate 32. The push rod 36 is located inside the spring 35; on one side of the top of the box body 1, a first electric telescopic rod 5 is fixed. The telescopic end of the first electric telescopic rod 5 is fixed with a push plate 51 located inside the box body 1 and used to push the push rod 36. The fixing plate 34 is U-shaped. After the tea powder is screened by the filter box 3, the cylinder 2 is rotated 90° clockwise. After the filter box 3 is in a horizontal state (transverse), it is located directly below the push plate 51. Then, the first electric telescopic rod 5 is started to move the push plate 51 downward, pushing the push rod 36 downward. After the spring 35 is stretched, the perforated plate 32 is separated from the sealing plate 31 and approaches the inner wall of the filter box 3. The perforated plate 32 can cooperate with the inner wall of the filter box 3 to crush the agglomerated tea powder, causing the tea powder to fall downward through the filter holes on the filter box 3, further avoiding waste of tea powder; subsequently, the push plate 51 and the spring 35 are restored. After the perforated plate 32 continues to fit on the sealing plate 31, the insertion rods 33 are inserted into the perforations on the perforated plate 32, pushing out the tea powder blocked in the perforations of the perforated plate 32 and avoiding waste caused by the tea powder being blocked in the perforations; and when the spring 35 rebounds, the vibration generated when the perforated plate 32 impacts the sealing plate 31 can shake off the tea powder adhering to the perforated plate 32.

[0018] As Figure 1 and Figure 2 shown, a connecting shell 6 is fixed on one side of the box body 1. A second electric telescopic rod 61 is fixed inside the connecting shell 6. The telescopic end of the second electric telescopic rod 61 is fixed with a bearing plate 62 that passes through the box body 1; the bearing plate 62 is used to support the side of the filter box 3 away from its open area. The connecting shell 6 is fixed to the box body 1 by screws. An opening for the bearing plate 62 to pass through is provided on the box body 1; when the push plate 51 moves downward, the telescopic end of the second electric telescopic rod 61 extends, causing the bearing plate 62 to enter the box body 1 and come into contact with the side of the filter box 3 away from its open area, supporting the filter box 3 and preventing impurities blocked in the sieve holes of the filter box 3 from being squeezed out and mixed in the tea powder; when the agglomerated tea powder is crushed, the bearing plate 62 is restored, and the crushed tea powder in the filter box 3 falls downward through the filter holes on the filter box 3. When the bearing plate 62 is restored and enters the connecting shell 6, the top and bottom of the bearing plate 62 are in contact with the top and bottom inside the opening on the box body 1, respectively, and the tea powder accumulated on the top of the bearing plate 62 can be pushed down.

[0019] As Figure 1 , Figure 2 and Figure 3 shown, a set of discharge frames 21 are connected to the cylinder 2. Extension plates are respectively fixed on the discharge frames 21 and the filter frames 3, and the extension plates on the discharge frames 21 and the filter frames 3 are fixed by bolts; A motor 11 is fixed on one side of the box body 1. The rotating shaft of the motor 11 penetrates through the box body 1 and is fixed to the side of the cylinder 2 away from the open end. A door panel 12 is hinged on the box body 1. The setting of a set of filter frames 3 enables the filter frame 3 directly below the cylinder 2 to load tea powder. After the cylinder 2 rotates clockwise by 90°, when the filter frame 3 is in a horizontal state, another adjacent filter frame 3 is located directly below the cylinder 2 to continue loading tea powder; The motor 11 is a servo motor. At this time, the motor 11 drives the cylinder 2 to rotate repeatedly in small amplitudes, so that after the tea powder in the filter frame 3 shakes, it can be better discharged through the filter holes on the filter frame 3; And the setting of a set of filter frames 3 can improve the screening efficiency of tea powder. When the tea powder in the horizontal filter frame 3 (the filter frame 3 on the left side of the cylinder 2, in the Figure 1 orientation shown in) is screened out, the cylinder 2 continues to rotate clockwise by 90°. After the filter frame 3 is in a vertical state, the impurities in the filter frame 3 can be cleaned, so as to be better put into the screening of tea powder subsequently; And when the cylinder 2 rotates, the tea powder discharged from the feed pipe 42 accumulates at the bottom of the cylinder 2, so that when the next filter frame 3 moves directly below the cylinder 2, the efficiency of loading the tea powder into the filter frame 3 can be improved, the loading efficiency of the tea powder is improved, and the screening efficiency of the tea powder is also improved; When maintenance of the filter frame 3 is required, after the door panel 12 is opened and the bolts on the extension plates of the discharge frame 21 and the filter frame 3 are removed, the filter frame 3 can be taken down.

[0020] As Figure 2 and Figure 3 shown, a vibrator 46 with a vibrating end connected to the inner wall of the fixed ring 41 is fixed on the circular plate 4 through a bearing strip. Two arc-shaped blocks 45 that are respectively in contact with the outer wall of the fixed ring 41 and the inner wall of the cylinder 2 are fixed on the top of the collection frame 43; The discharge end of the slag discharge pipe 44 is communicated with an external exhaust fan. After the vibrator 46 is started, the fixed ring 41 can be vibrated, so that the impurities on the fixed ring 41 can slide better towards the collection frame 43; The arc-shaped blocks 45 can prevent impurities from accumulating on the top of the collection frame 43, and the external exhaust fan can better extract the impurities in the collection frame 43 through the slag discharge pipe 44.

[0021] As Figure 1 , Figure 2 and Figure 6As shown, a fixed shell 7 is fixed on the top of the box body 1. A third electric telescopic rod 71 is fixed on the fixed shell 7. The telescopic end of the third electric telescopic rod 71 is fixed with a lifting frame 72 with one side open and the bottom penetrating through the top of the box body 1. A first hollow plate 73 is fixed on the top of the lifting frame 72. A first cleaning pipe 74 is communicated with the bottom of the first hollow plate 73. The first cleaning pipe 74 can be inserted into the filter holes on the side of the filter frame 3 away from the cylinder 2; On both sides of the lifting frame 72, a fourth electric telescopic rod 8 is fixed. The telescopic end of the fourth electric telescopic rod 8 is fixed with a second hollow plate 81 located inside the lifting frame 72. Second cleaning pipes 82 are communicated with the opposite surfaces of the two second hollow plates 81. The second cleaning pipes 82 can be inserted into the filter holes on one side of the filter frame 3. The fixed shell 7 is connected to the box body 1 by a screw. The first electric telescopic rod 5, the second electric telescopic rod 61 and the third electric telescopic rod 71 are all three-section telescopic rods; An entrance for the bottom of the lifting frame 72 to pass through is opened on the top of the box body 1. After the filter frame 3 after sieving the tea powder moves to the top of the cylinder 2, the third electric telescopic rod 71 can be started to make the lifting frame 72 move downward to cover the filter frame 3, and the open side of the lifting frame 72 corresponds to the fixed plate 34, which will not affect the normal lifting of the lifting frame 72; After the first cleaning pipe 74 is inserted into the filter holes on the side of the filter frame 3 away from the cylinder 2, the filter holes on the filter frame 3 can be dredged to prevent impurities from blocking in the filter holes; Subsequently, the lifting frame 72 moves upward to make the second cleaning pipe 82 correspond to the filter holes on one side of the filter frame 3, and then the two fourth electric telescopic rods 8 are started. After the two second hollow plates 81 move relative to each other, the second cleaning pipes 82 on the two second hollow plates 81 are respectively inserted into the filter holes on the front and back (in the Figure 1 orientation shown) of the filter frame 3 to dredge the impurities blocking in the filter holes, avoiding the impurities blocking in the filter holes from affecting the filtering efficiency of the tea powder.

[0022] As Figure 1 , Figure 2 and Figure 6 shown, a fixed frame 9 is fixed on one side of the lifting frame 72. A group of flexible hoses 91 are communicated with the fixed frame 9. The group of flexible hoses 91 are respectively communicated with the first hollow plate 73 and the two second hollow plates 81; A rubber pipe is communicated with the fixed frame 9, penetrates through the fixed shell 7 and is communicated with an external hair dryer. After the impurities in the filter holes on the filter frame 3 are dredged, the external hair dryer can be started to make the air enter the fixed frame 9 through the rubber pipe. Then, the air enters the first hollow plate 73 and the two second hollow plates 81 respectively through the group of flexible hoses 91, and then can be discharged from the ends of the first cleaning pipe 74 and the second cleaning pipes 82 and blown into the filter frame 3 to complete the cleaning of the impurities in the filter frame 3, making the impurities adhering to the inner wall of the filter frame 3 move better towards the inside of the cylinder 2; When the lifting frame 72 covers the filter frame 3, at this time, the motor 11 temporarily stops and does not drive the cylinder 2 to rotate.
