DETAILED DESCRIPTION

[0029] 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.

[0030] See also Figure 1-Figure 9The present invention provides a technical solution: a beverage clarification and filtration device, comprising a filter cartridge 1 and a filter box 2, wherein a feed pipe is connected to one side of the top of the filter cartridge 1, so as to facilitate pouring the beverage into the filter cartridge 1, and a discharge port is provided through the bottom of the filter box 2; wherein the filter cartridge 1 is arranged on the top of the filter box 2 and the two are connected to each other through a feed channel 3, and the feed channel 3 is in a long strip shape, and the length of the feed channel 3 is adapted to the length of the filter cartridge 1, so that the beverage in the filter cartridge 1 can flow to the inside of the filter box 2 as much as possible for the next processing step. A spiral conveying auger 4 for collecting the filter residue is provided inside the filter cartridge 1, and a feed channel 101 is provided through the side of the filter cartridge 1 away from the driving member 8, so that the filter residue is transported to the feed channel 101 along with the spiral conveying auger 4, so as to facilitate collection. A plurality of filter holes 5 are provided through the side wall of the filter cartridge 1 at a position relative to the feed channel 3, and the filter holes 5 are connected to the feed channel 3, and the aperture of the filter holes 5 can be set according to demand. By pouring the beverage into the filter cartridge 1, the beverage and the smaller filter residue flow into the filter box 2 through the filter holes 5 and the feed channel 3, while the larger filter residue is blocked by the filter holes 5 in the filter cartridge 1 and is transported to the feed channel 101 along with the spiral conveying auger 4. The first filter plate 6 and the second filter plate 7 for filtering the beverage are rotatably arranged inside the filter box 2, and a plurality of filter holes are penetrated and opened on the first filter plate 6 and the second filter plate 7, wherein the diameter of the filter holes on the first filter plate 6 and the second filter plate 7 decreases from top to bottom, and the apertures are smaller than the aperture of the filter hole 5, so as to facilitate the filtering of filter residues of different sizes in sequence, and by setting a plurality of filtering devices, the filter holes are not easily blocked, thereby improving the filtering efficiency of the beverage.

[0031] For this explanation, the first filter plate 6 and the second filter plate 7 are both inclined, and the downwardly inclined side of the first filter plate 6 and the second filter plate 7 is rotatably connected to the inner wall of the filter box 2. In the initial state, the angle between the first filter plate 6 and the second filter plate 7 and the horizontal plane is less than 5°, and the first filter plate 6 and the second filter plate 7 are inclined in opposite directions, which is convenient for the staff to effectively collect the discharged filter residue in different directions. The first filter plate 6 is inclined in the direction of low left and high right, and the second filter plate 7 is inclined in the direction of high left and low right.

[0032] An extension portion 601 is fixedly provided on the top of the first filter plate 6 and the second filter plate 7, and a rotating shaft is fixedly provided on the front and rear sides of the extension portion 601. One end of the rotating shaft away from the extension portion 601 is rotatably connected to the inner wall of the filter box 2. Through the setting of the rotating shaft, while providing support for the extension portion 601, one side of it can also be limited so that the side cannot move. By setting the extension part 601, the filter residue filtered out from the first filter plate 6 and the second filter plate 7 can be blocked to prevent the filter residue from falling from the edges of the first filter plate 6 and the second filter plate 7 to the bottom of the filter box 2, and one side of the extension part 601 is designed to be open, and the open part is set on the extension part 601 and is located at the lower part of the first filter plate 6 and the second filter plate 7, so that when the first filter plate 6 and the second filter plate 7 are tilted, the blocked filter residue can fall along their surface to the open part, and finally be sent out from the discharge pipe 201, so as to facilitate the collection of the filter residue; the left and right side walls of the filter box 2 are connected with the discharge pipe 201, and the open ends of the first filter plate 6 and the second filter plate 7 extend to the inside of the discharge pipe 201.

[0033] For illustration, slag discharge ports are provided on both sides of the inner wall of the filter box 2, the feed pipe 201 is connected to the slag discharge ports, and one end of the first filter plate 6 and the second filter plate 7 extend to the inside of the two slag discharge ports respectively.

[0034] A driving member 8 for driving the spiral conveying auger 4 to rotate is provided on the outside of the filter cylinder 1, and a connecting transmission assembly 9 is provided on the outside of the filter box 2. The connecting transmission assembly 9 partially extends into the interior of the filter box 2 and is connected to the first filter plate 6 and the second filter plate 7. During operation, the driving member 8 drives the first filter plate 6 and the second filter plate 7 to rotate around the connection with the filter box 2 through the connecting transmission assembly 9. The first filter plate 6 and the second filter plate 7 are tilted in opposite directions during the rotation process, so that during the filtration process, the first filter plate 6 and the second filter plate 7 can vibrate to prevent their filter holes from being blocked and improve their service life. At the same time, during the rotation process, the first filter plate 6 and the second filter plate 7 will tilt, so that the blocked filter residue can fall along its surface to the discharge pipe 201, which is convenient for collecting the filtered filter residue.

[0035] In the design scheme, the driving member 8 includes a driving shaft 801 that is rotatably arranged on the side wall of the filter cartridge 1, one end of the spiral conveying auger 4 is fixedly connected to the end of the driving shaft 801, and a power member 802 is fixedly arranged on the outside of the filter cartridge 1. The power member 802 is a motor and is electrically connected to an external power source; wherein the output shaft of the power member 802 is fixedly arranged with the end of the driving shaft 801 through a coupling. By starting the power member 802 to drive the driving shaft 801 to rotate, the driving shaft 801 drives the spiral conveying auger 4 to rotate, thereby transporting the blocked filter residue.

[0036] For this purpose, the output shaft of the power member 802 penetrates the side wall of the filter cartridge 1 and is rotatably connected to the inner wall thereof, and the end of the output shaft of the power member 802 is fixedly connected to one end of the spiral conveying auger 4 .

[0037] Among them, regarding the design scheme of the connecting transmission assembly 9, the connecting transmission assembly 9 includes a transmission shaft 901 rotatably arranged on the side wall of the filter box 2, and the transmission shaft 901 is connected to the outer surface of the drive shaft 801 through a transmission member 902. The transmission member 902 includes a pulley fixedly arranged on the outer surface of the transmission shaft 901 and the drive shaft 801, and the outer surfaces of the two pulleys are connected by belt transmission, so that when the drive shaft 801 rotates, the transmission shaft 901 can be driven to rotate synchronously. A connecting shaft 903 is rotatably arranged on the side wall of the filter box 2, wherein the drive shaft 801 drives the transmission shaft 901 to rotate through the transmission member 902, so that the transmission shaft 901 gradually approaches the connection shaft 903 during the rotation process and pushes the connection shaft 903 to rotate, thereby driving the first filter plate 6 and the second filter plate 7 to rotate around the connection with the filter box 2, and when the transmission shaft 901 is separated from the connection shaft 903, the first filter plate 6 and the second filter plate 7 are restored to their original state.

[0038] As a further technical solution, the outer surface of the transmission shaft 901 extends outward to form a transmission protrusion 904. Preferably, two transmission protrusions 904 are provided and are symmetrically arranged about the axis of the transmission shaft 901; the outer surface of the connecting shaft 903 is fixedly provided with a transmission boss 905, wherein, when the transmission shaft 901 drives the transmission protrusion 904 to rotate, the transmission protrusion 904 gradually contacts the transmission boss 905 and pushes the connecting shaft 903 to rotate, until the transmission protrusion 904 is disengaged from the transmission boss 905, and the transmission boss 905 is reset, thereby driving the first filter plate 6 and the second filter plate 7 to reciprocate around the connection with the filter box 2.

[0039] As a further technical solution, a transmission turntable 906 is fixedly provided at the end of the connecting shaft 903, and a top rod 907 located at the bottom of the first filter plate 6 and the second filter plate 7 is slidably provided inside the filter box 2. A vertical slide groove is provided on the inner wall of the filter box 2, and the end of the top rod 907 extends into the vertical slide groove and is slidably provided with the inner wall thereof. The moving direction of the top rod 907 is limited by the provision of the vertical slide groove, thereby improving its stability during movement. A transmission support rod 9010 is rotatably provided between the top rod 907 and the transmission turntable 906, and a reset torsion spring 908 is fixedly provided on the outer surface of the connecting shaft 903, wherein one end of the reset torsion spring 908 is fixedly connected to the side wall of the filter box 2.

[0040] For this purpose, the outer surface of the top rod 907 is wrapped with a rubber ring; one end of the transmission support rod 9010 is sleeved on the outer surface of the top rod 907, and the other end of the transmission support rod 9010 is rotatably connected to the edge of the transmission turntable 906, so that when the transmission turntable 906 rotates, the top rod 907 can be driven by the transmission support rod 9010 to move up and down in the vertical slide groove, thereby pushing the first filter plate 6 and the second filter plate 7 to further rotate; and the rotation angle of the transmission turntable 906 is less than 25°.

[0041] like Figures 7 to 9 As shown, as a further technical solution, a support column 909 is fixedly provided on the inner wall of the filter box 2, and the position of the support column 909 is higher than the position of the slag discharge port, so that in the initial state, the first filter plate 6 and the second filter plate 7 are still in an inclined state; the outer surface of the support column 909 is covered with a rubber layer, so that the first filter plate 6 and the second filter plate 7 provide a buffering force when they are reset, thereby improving the service life of the first filter plate 6 and the second filter plate 7; the support columns 909 are respectively located at the bottom of the first filter plate 6 and the second filter plate 7. Through the setting of the support columns 909, the bottom of the first filter plate 6 and the second filter plate 7 away from the slag discharge port is supported, thereby improving the stability of the first filter plate 6 and the second filter plate 7.

[0042] When the drive shaft 801 rotates, the transmission shaft 901 rotates synchronously through the transmission member 902. The rotation of the transmission shaft 901 drives the transmission protrusion 904 to rotate around its axis. During the rotation, the transmission protrusion 904 gradually approaches the transmission boss 905 and contacts it. At this time, the transmission protrusion 904 continues to rotate, thereby pushing the transmission boss 905 to rotate clockwise. The transmission boss 905 drives the transmission turntable 906 to rotate clockwise through the connecting shaft 903, so that the transmission turntable 906 pulls the top rod 907 to move through the transmission support rod 9010 during the rotation, so that the lower top rod 907 moves upward along the vertical slide groove, pushing the second The filter plate 7 rotates upward around the connection with the filter box 2, and at the same time, the upper push rod 907 moves downward along the vertical slide groove. At this time, the upper push rod 907 releases the limiting effect on the first filter plate 6, so that the first filter plate 6 rotates downward around the connection with the filter box 2 under the action of gravity; when the transmission protrusion 904 rotates to disengage from the transmission protrusion 905, at this time, under the action of the reset torsion spring 908, the connecting shaft 903 is driven to rotate in the opposite direction for reset, thereby driving the first filter plate 6 and the second filter plate 7 to reciprocate around the connection with the filter box 2, causing them to vibrate, and transporting the blocked filter residue to the discharge pipe 201 for collection.

[0043] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0044] During operation, the beverage is first poured into the filter cartridge 1, and then the power member 802 is started to drive the drive shaft 801 to rotate, and the drive shaft 801 drives the spiral conveying auger 4 to rotate to transport the blocked filter residue. At the same time, the smaller filter residue and beverage fall into the filter box 2 through the filter hole 5, and pass through the first filter plate 6 and the second filter plate 7 in sequence. At the same time, the drive shaft 801 rotates synchronously with the transmission shaft 901 through the transmission member 902 during the rotation process. The rotation of the transmission shaft 901 drives the transmission protrusion 904 to rotate around its axis. The transmission protrusion 904 gradually approaches the transmission protrusion 905 during the rotation process and rotates with it. When the transmission protrusion 904 is rotated to be disengaged from the transmission protrusion 905, the connecting shaft 903 is driven to rotate in the opposite direction under the action of the reset torsion spring 908, thereby resetting and driving the push rod 907 to reciprocate in the vertical direction and push the first filter plate 6 and the second filter plate 7 to reciprocate around the connection with the filter box 2.
