[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1 and 2As shown, a waste residue filtering device for extracting tea concentrate comprises: an outer shell 1; a filter inner cylinder 2, wherein the filter inner cylinder 2 is arranged in the outer shell 1, the middle part of the filter inner cylinder 2 is in rolling contact with the inner wall of the outer shell 1, and one end of the filter inner cylinder 2 is eccentrically provided with a first filter outlet 201; and a liquid outlet pipe 3, wherein the liquid outlet pipe 3 is arranged at one side of the bottom of the outer shell 1, so that after the tea concentrate reaches the outer shell 1 through the first filter outlet 201, it is rolled and ground by the filter inner cylinder 2 and discharged through the liquid outlet pipe 3; a second filter outlet 101 is provided at one end of the outer shell 1 away from the first filter outlet 201, and the second filter outlet 101 corresponds to the entrance end of the liquid outlet pipe 3.

[0024] It should be noted that, in the process of filtering the waste residue of the tea concentrate, the tea concentrate to be filtered can be filled into the filter inner cylinder 2. During the rotation of the filter inner cylinder 2, when the first filter outlet 201 drops to the lowest point, the tea concentrate is filtered into the outer shell 1 through the first filter outlet 201. After the tea concentrate enters the outer shell 1, it will be rolled and ground by the filter inner cylinder 2 rotating in the outer shell 1, so that the tea concentrate is crushed again. After the crushing is completed, it will reach the other side of the outer shell 1, and will be discharged into the liquid outlet pipe 3 through the second filter outlet 101, and discharged from the liquid outlet pipe 3. By filtering the tea concentrate in the above manner, the tea concentrate can be intermittently released from the filter inner cylinder 2 into the outer shell 1 and rolled and ground by the filter inner cylinder 2, thereby improving the crushing effect of the tea concentrate. Moreover, after grinding, it is filtered and processed through the second filter outlet 101 and then discharged, which can effectively improve the treatment effect of the waste residue in the tea concentrate.

[0025] like Figure 1 As shown, the outer shell 1 includes: a bracket 11; a shell base 12, which is movably mounted on the bracket 11; and an adjustment motor 13, which is mounted on the bracket 11, and the power output end of the adjustment motor 13 is connected to the shell base 12 to drive the shell base 12 to be tilted, and the tea concentrate is re-grinded by rolling the filter inner cylinder 2 in the shell base 12.

[0026] In this embodiment, when the tea concentrate is discharged from the first filter outlet 201 in the filter inner cylinder 2, the adjustment motor 13 drives the shell base 12 on the bracket 11 to rotate, so that the tea concentrate in the filter inner cylinder 2 is gradually filtered and discharged into the outer shell 1. Further, the shell base 12 is reversely turned by the reverse rotation of the adjustment motor 13, which is preferably a servo motor, so that the tea concentrate passes through the rolling grinding area between the shell base 12 and the filter inner cylinder 2, and after rolling grinding of the filter inner cylinder 2, reaches the second filter outlet 101 for discharge after waste residue filtration.

[0027] like Figure 2 and Figure 3 As shown, the filtering inner cylinder 2 comprises: an inner cylinder 21, a curved grinding surface 22 is provided in the middle of the inner cylinder 21, the curved grinding surface 22 is in contact with the inner wall of the outer shell 1, and the first filtering outlet 201 is eccentrically arranged at one end of the inner cylinder 21; a first filter screen 23, the first filter screen 23 is installed on the first filtering outlet 201 to perform preliminary filtering on the tea concentrate in the inner cylinder 21; and a driving component 24, the driving component 24 is installed on the outer shell 1, and the power output end of the driving component 24 is connected to the inner cylinder 21, so that the first filtering outlet 201 and the first filter screen 23 rotate eccentrically.

[0028] In this embodiment, when the filter inner cylinder 2 is preliminarily filtering the tea concentrate, the driving assembly 24 can drive the inner cylinder 21 to rotate, so that the tea concentrate that has been preliminarily filtered is ground between the outer arc-shaped grinding surface 22 of the inner cylinder 21 and the inner side wall of the outer shell 1. At the same time, when the first filter outlet 201 and the first filter screen 23, which are eccentrically arranged at one end of the inner cylinder 21, drop to the lowest point, they also correspond to reaching below the liquid level of the tea concentrate in the inner cylinder 21, so that the tea concentrate that is higher than the lowest end of the first filter screen 23 flows out into the outer shell 1 through the first filter screen 23.

[0029] Furthermore, the driving assembly 24 includes: a driving shaft 241, which is a hollow structure, and one end of the driving shaft 241 is connected to the inner cylinder 21; an input pipe 242, one end of the input pipe 242 is movably connected to the driving shaft 241, so as to input tea concentrate into the inner cylinder 21 through the driving shaft 241; and a driving motor 243, the driving motor 243 is installed on the outer shell 1, and the power output end of the driving motor 243 is connected to the inner cylinder 21.

[0030] In this embodiment, when the driving assembly 24 drives the inner cylinder 21 to rotate, the driving motor 243, which is preferably a servo motor, drives the driving shaft 241 to rotate, thereby driving the inner cylinder 21 to rotate together, so that the first filtering outlet 201 is continuously raised and lowered, so as to intermittently complete the preliminary filtering treatment of the tea concentrate. In addition, the tea concentrate can also be input to the driving shaft 241 through the input pipe 242, and then input into the inner cylinder 21 through the driving shaft 241.

[0031] Specifically, the input pipe 242 includes: a tube body 2421; and a sleeve 2422, one end of the tube body 2421 is connected to the sleeve 2422, the sleeve 2422 is sleeved on the driving shaft 241, and the driving shaft 241 is provided with a through hole corresponding to the sleeve 2422.

[0032] In this embodiment, when the input tube 242 inputs the tea concentrate into the driving shaft 241, the tea concentrate passes through the tube body 2421 to the sleeve 2422, and enters the driving shaft 241 through the corresponding through hole on the driving shaft 241, and further enters the inner cylinder 21. When the driving shaft 241 rotates, the sleeve 2422 can seal the through hole.

[0033] like Figure 2 and Figure 4 As shown, the liquid outlet pipeline 3 includes: a liquid outlet pipe 31; and a valve 32, wherein the valve 32 is installed on the liquid outlet pipe 31 to control the discharge of the tea concentrate.

[0034] In this embodiment, when the liquid outlet pipe 3 discharges the tea concentrate, the valve 32 can be used to control the liquid outlet pipe 31 to control the discharge of the tea concentrate and stop the discharge. Specifically, the valve 32 can be a solenoid valve.

[0035] Furthermore, a second filter screen 14 is installed on the second filter outlet 101 to filter the tea concentrate ground by the filter inner cylinder 2 again and then discharge it through the liquid outlet pipe 3 .

[0036] In this embodiment, at the second filter outlet 101, a second filter screen 14 may be provided to filter the ground tea concentrate again and discharge it after filtering.

[0037] Preferably, the radial size of the filtering holes of the first filter net 23 is larger than the radial size of the filtering holes of the second filter net 14 .

[0038] In this embodiment, by designing the radial size of the filter holes of the first filter 23 to be larger than the radial size of the filter holes of the second filter 14, primary filtration before grinding can be achieved through the first filter 23, and secondary filtration after grinding can be achieved through the second filter 14.

[0039] like Figure 2 As shown, the filtering device further comprises: a hole cleaning component 4 , which is mounted on the outer shell 1 to perform air blowing cleaning on the filter holes of the first filter screen 23 that rotates to a height corresponding to the hole cleaning component 4 .

[0040] In this embodiment, when the first filter screen 23 is filtering the tea concentrate, the filter holes of the first filter screen 23 can be cleaned by blowing air through the hole cleaning component 4 to ensure the re-filtering effect of the first filter screen 23 .

[0041] Furthermore, the hole cleaning component 4 includes: an air outlet pipe 41, the size of the outlet end of the air outlet pipe 41 is smaller than the size of the first filter 23; a driven gear, the driven gear is installed on the air outlet pipe 41, and the driven gear is inserted in the outer shell 1; a fan 42, the fan 42 is installed on the outer shell 1, and the air outlet of the fan 42 corresponds to the air outlet pipe 41; and a driving motor 43, the driving motor 43 is installed on one side of the fan 42, and the power output end of the driving motor 43 is meshed with the driven gear through a driving gear.

[0042] In one embodiment of the present invention, when cleaning, the hole cleaning component 4 can drive the air outlet pipe 41 at one end of the air outlet of the fan 42 to rotate through the driving motor 43, which is preferably a servo motor, so that the air outlet pipe 41 whose outlet end size is smaller than the size of the first filter 23 rotates and blows the first filter 23, thereby ensuring all-round cleaning of the first filter 23.

[0043] In summary, the waste residue filtering device for extracting tea concentrate disclosed by the present invention can effectively improve the treatment effect of waste residue in tea concentrate by cooperating between the filter inner cylinder 2 and the outer shell 1. The tea concentrate entering the filter inner cylinder 2 will be intermittently discharged into the outer shell 1 through the eccentrically arranged first filter outlet 201, and the tea concentrate after pre-filtering treatment will be ground again by the filter inner cylinder 2 and the outer shell 1, and after grinding and crushing, it will be filtered again through the second filter outlet 101 on the outer shell 1 and discharged through the liquid outlet pipe 3.
