Description

Technical Field

[0001] The utility model relates to the technical field of concentrated liquid, in particular to a centrifugal filtering device for concentrated liquid. Background Art

[0002] Concentrate is something that has been made more concentrated. Common concentrates in life include concentrated fruit juice. When concentrated fruit juice is produced, the fruit residue in the juice needs to be filtered out in order to improve the taste of the juice.

[0003] The existing centrifugal filtration device for fruit juice concentrate is generally a disc centrifuge. There is a group of disc-shaped parts stacked together in the drum, with a small gap between the discs. The concentrate is added to the drum through the feed pipe located in the center of the drum. When the concentrate flows through the gap between the discs, the residue settles on the discs under the action of the centrifuge to form sediment. The sediment slides along the surface of the disc and separates from the disc and accumulates in the largest diameter part of the drum. The separated liquid is discharged from the drum from the liquid outlet. The concentrated juice will also have different concentrations due to the different water content of the fruit in the body. For example, hawthorn has a lower water content, so the concentration of hawthorn concentrate is higher, and a higher speed is required for centrifugal separation of hawthorn residue; on the contrary, orange has a higher water content, and the concentration of orange concentrate is lower, so a too high speed is not required for centrifugal separation of orange residue. When the existing stacked centrifuge adjusts the speed according to the concentration of different fruit juice concentrates, it mainly relies on changing the power supply of the motor, making it difficult for the motor to always maintain the most ideal state of driving, and it is easy to reduce the service life of the motor after long-term use; in view of this, we propose a centrifugal filtration device for concentrates.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0022] Example:

[0023] This embodiment discloses a centrifugal filtration device for concentrated liquid, see Figures 1 to 5 , including a disc centrifuge 1 and a speed changing mechanism 2.

[0024] like Figure 1 , Figure 2 As shown, the disc centrifuge 1 includes a bottom plate 101, a motor 102 is provided on one side of the bottom plate 101 surface, and a centrifugal mechanism 103 is provided on one side of the motor 102; and the output end of the motor 102 and the driving end of the centrifugal mechanism 103 are transmitted through a speed change mechanism 2. In this embodiment, the disc centrifuge 1 is an existing centrifugal filtration device for concentrated juice residue on the market, and the speed change mechanism 2 is used to change the centrifugal speed of the centrifugal mechanism 103 without changing the rotation speed of the motor 102, so that the motor 102 always maintains the most suitable rotation speed, which is convenient for separating juice residues of different concentrations.

[0025] like Figures 1 to 5 As shown, the speed change mechanism 2 is arranged between the motor 102 and the centrifugal mechanism 103 .

[0026] Specifically, Figure 1 , Figure 2As shown, the speed change mechanism 2 includes a gear column 201, a long shaft 202 and a grinding disc A203; both ends of the gear column 201 are rotatably connected to the surface of the base plate 101 through a rotating shaft and a mounting seat A, and one end of the gear column 201 is transmitted to the output end of the motor 102 through a bevel gear set, the long shaft 202 is arranged on one side of the gear column 201, and the middle part of the long shaft 202 is rotatably connected to the surface of the base plate 101 through a mounting seat B, a gear 204 is sleeved on the middle surface of the long shaft 202, the gear 204 is meshed with the gear column 201, the center of the top surface of the grinding disc A203 is fixedly connected to the driving end of the centrifugal mechanism 103, the long shaft 202 is fixedly connected to the grinding disc B205 relative to the grinding disc A203, the surface of the grinding disc B205 is movably connected to a friction strip 206, the surface of the friction strip 206 is connected to the surface of the grinding disc A203, the other end of the long shaft 202 is rotatably connected to a threaded rod 207, and the surface of the threaded rod 207 is threadedly connected to a mounting seat Mounting seat C, one end of the threaded rod 207 is fixedly connected with a handwheel 208, and the motor 102 is driven by an external control mechanism. The motor 102 drives the gear column 201 to rotate through the bevel gear set, and the gear column 201 drives the gear 204 to rotate. The gear 204 drives the long shaft 202 to rotate at one end of the threaded rod 207, thereby driving the grinding disc B205 and the friction strip 206 to rotate. The friction strip 206 drives the grinding disc A203 to rotate and then drives the centrifugal mechanism 103 to rotate. The threaded rod 207 is driven by handwheel 208, and the threaded rod 207 spirally advances or retreats on the mounting seat C, thereby pushing the grinding disc B205 toward the center of the grinding disc A203 or pulling the grinding disc A203 toward the edge of the grinding disc A203. When the grinding disc B205 is close to the center of the grinding disc A203, the friction strip 206 is close to the center of the grinding disc A203, so the rotation of the grinding disc B205 can increase the rotation speed of the grinding disc A203, and vice versa. Reduce the rotation speed of the grinding disc A203.

[0027] Further, such as Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, a slot 2051 adapted to the friction strip 206 is provided on the surface of the grinding disc B205, a plurality of plug blocks 2061 are provided on the inner wall of the friction strip 206 at equal intervals, a slot A2052 adapted to the plug block 2061 is provided at a position of the grinding disc B205 relative to the plug block 2061, two connecting blocks 2062 are axially symmetrically provided at both ends of the friction strip 206, the two connecting blocks 2062 are provided with threaded holes A2063 connected to each other, a slot B2053 connected to the slot 2051 is provided on the surface of the grinding disc B205 relative to the two connecting blocks 2062, threaded holes B2054 are provided inside on both sides of the slot B2053, the threaded holes B2054 and the threaded holes A2063 are connected to each other to form a mounting hole, the threaded holes B2054 and the threaded holes A2063 are connected to each other to form a mounting hole, and a screw 2055 is connected to the inner thread of the mounting hole formed by the mutual connection of the threaded holes B2054 and the threaded holes A2063. The speed change mechanism 2 mainly relies on the friction force between the friction strip 206 and the grinding disc A203 for transmission. Therefore, after long-term use, the surface of the friction strip 206 will be greatly worn, resulting in reduced transmission efficiency. The friction strip 206 with severe wear can be removed by rotating the screw 2055 from the mounting hole formed by the threaded hole B2054 and the threaded hole A2063 connected to each other with a screwdriver, and the friction strip 206 with severe wear can be removed. The plug blocks 2061 on the new friction strip 206 are inserted into the slots A2052 in turn, and then the threaded holes A2063 on the two connecting blocks 2062 are aligned and inserted into the slots B2053, and the screws 2055 are screwed into the mounting hole formed by the threaded holes B2054 and the threaded holes A2063 connected to each other. At this time, the slots 2051 clamp the two sides of the friction strip 206, so that the new friction strip 206 can be fixed, which is convenient for the disassembly and replacement of the friction strip 206.

[0028] Further, if Figure 4 , Figure 5 As shown, the outer wall of the friction strip 206 is provided with a plurality of arc-shaped stripes 2064 extending to the outside of the slot 2051. The friction strip 206 is made of soft rubber material, which facilitates the installation of the friction strip 206 and improves the friction between the friction strip 206 and the surface of the grinding wheel A203.

[0029] It is worth noting that if Figure 2 , Figure 3 As shown, a limiting plate 2021 with a diameter larger than that of the long axis 202 is provided at the opposite end of the long axis 202 and the threaded rod 207, a rotation groove 2071 adapted to the opposite end of the long axis 202 is opened at the opposite end of the threaded rod 207 and the threaded rod 207 has a limiting groove 2072 connected to the rotation groove 2071 and adapted to the limiting plate 2021 opened along the rotation groove 2071 of the threaded rod 207. The long axis 202 rotates, driving one end of the long axis 202 to rotate in the rotation groove 2071, and the limiting plate 2021 rotates in the limiting groove 2072, ensuring that the rotation of the long axis 202 is not affected by the threaded rod 207, and the long axis 202 will not detach from the threaded rod 207.

[0030] Working principle: When the utility model is used, the concentrated juice that needs to be centrifugally filtered is first injected into the centrifugal mechanism 103, and the external control mechanism drives the motor 102. The motor 102 drives the gear column 201 to rotate through the bevel gear set, and the gear column 201 drives the gear 204 to rotate. The gear 204 drives the long shaft 202 to rotate at one end of the threaded rod 207, thereby driving the grinding disc B205 and the friction strip 206 to rotate. The stripes 2064 on the friction strip 206 drive the grinding disc A203 to rotate and then drive the centrifugal mechanism 103 to rotate, and the concentrated juice residue is centrifugally filtered. When it is necessary to filter juice of different concentrations, the threaded rod 207 is rotated by hand wheel 208, and the threaded rod 207 spirally moves forward or backward on the mounting seat C, thereby pushing the grinding disc B205 toward the center of the grinding disc A203 or pulling the grinding disc B205 toward the edge of the grinding disc A203. When the grinding disc B205 is close to the center of the grinding disc A203, the friction strip 206 is close to the center of the grinding disc A203, so the grinding disc The rotation of B205 can increase the rotation speed of the grinding disc A203, and vice versa, the rotation speed of the grinding disc A203 can be reduced. The centrifugal speed of the centrifugal mechanism 103 can be changed without changing the rotation speed of the motor 102, so that the motor 102 always maintains the most suitable rotation speed, which is convenient for separating juice residues of different concentrations; the friction strip 206 with severe wear can be removed by rotating and removing the screw 2055 from the mounting hole formed by the threaded hole B2054 and the threaded hole A2063 connected to each other with a screwdriver, and the insert block 2061 on the new friction strip 206 is inserted into the slot A2052 in turn, and then the threaded holes A2063 on the two connecting blocks 2062 are aligned and inserted into the slot B2053, and the screw 2055 is screwed into the mounting hole formed by the threaded hole B2054 and the threaded hole A2063 connected to each other. At this time, the slot 2051 clamps the two sides of the friction strip 206, and the new friction strip 206 can be fixed, which is convenient for disassembly and replacement of the friction strip 206.
