Description

Technical Field

[0001] This application relates to the field of centrifuges, and more specifically, to a centrifuge for separating and purifying food additives. Background Technology

[0002] Food additives are artificial or natural substances added to food to improve its color, aroma, and taste, as well as for preservation and processing needs. During the production of food additives, solid-liquid separation is required for the raw materials to facilitate the extraction of substances.

[0003] The separation and extraction can be accomplished using a centrifuge. The centrifuge has a filter screen inside. When it rotates at high speed, solids are filtered onto the filter screen, while liquids pass through the filter screen and are discharged. In existing solid-liquid separation centrifuges, the filter screen is installed inside the machine body and rotates at high speed with the shaft. Therefore, there is a situation where solid substances are adsorbed onto the filter screen, so the filter screen needs to be cleaned regularly. However, the filter screen is inconvenient to remove from the shaft. Therefore, we propose a centrifuge for the separation and purification of food additives. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a centrifuge for separating and purifying food additives, which aims to improve the problem of inconvenient disassembly of the internal filter screen of the centrifuge.

[0005] This application provides a centrifuge for separating and purifying food additives, including a body. A cover plate is installed on the top of the body, and a conveying mechanism is rotatably passed through the cover plate. A connecting plate is connected to the bottom of the conveying mechanism, and a dual-stage filter cartridge is inserted into the bottom of the connecting plate. A locking component is also installed on the top of the connecting plate, and the locking component is inserted into the dual-stage filter cartridge.

[0006] In one specific implementation, the conveying mechanism includes a conveying pipe that rotatably passes through the cover plate, a guide tube that is rotatably connected to the top of the conveying pipe, a positioning plate that is connected between the guide tube and the top of the cover plate, and a connecting disc that is fixedly sleeved on the bottom of the outer wall of the conveying pipe.

[0007] In one specific implementation, the conveying mechanism further includes a motor mounted on the top of the cover plate, the motor being driven by the conveying pipe.

[0008] In one specific implementation, the dual-stage filter cartridge includes a first filter cartridge and a second filter cartridge, the first filter cartridge being located inside the second filter cartridge, and a connecting ring being fixedly connected to the top of both the first and second filter cartridges, with the two connecting rings fitting against the bottom of the connecting disc.

[0009] In one specific implementation, two positioning blocks are fixedly connected to the top of each of the two connecting rings, and the four positioning blocks slide through the connecting disc. A common insert block slides through between two adjacent positioning blocks, and the insert block is locked with the locking member.

[0010] In one specific implementation, the locking component includes an arc-shaped block fixedly installed on the top of the connecting plate. Arc-shaped grooves are provided on both ends of the sidewalls of the arc-shaped block. Arc-shaped rods are slidably provided in both arc-shaped grooves. A spring is connected between the arc-shaped rods and the sidewalls of the arc-shaped grooves. The two arc-shaped rods are respectively inserted into the two blocks.

[0011] In one specific implementation, a discharge pipe extends through the bottom of the machine body, and the bottoms of the first filter cylinder and the second filter cylinder are both sleeved on the discharge pipe.

[0012] In one specific implementation, a sealing tube is inserted inside the discharge pipe.

[0013] The beneficial effects of this application are as follows: By installing a detachable cover plate on the top of the machine body, a conveying pipe is rotatably passed through the cover plate, a connecting plate is installed at the bottom of the conveying pipe, and a first filter cylinder and a second filter cylinder are installed at the bottom of the connecting plate, so as to achieve dual-stage filtration. Thus, during solid-liquid separation, solids of different sizes are respectively placed in the first filter cylinder and the second filter cylinder, which facilitates centrifugal separation in the food additive production process. At the same time, a connecting ring is installed on the top of the first filter cylinder and the second filter cylinder, and a positioning block is installed on the top of the connecting ring. The positioning block is connected to the locking part on the connecting plate, which facilitates the disassembly and assembly of the first filter cylinder and the second filter cylinder, thus facilitating disassembly and cleaning.

Detailed Implementation

[0023] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0024] Please see Figure 1-7 This application provides a centrifuge for separating and purifying food additives, including a body 10. A cover plate 20 is installed on the top of the body 10, and a conveying mechanism 30 is rotatably passed through the cover plate 20. A connecting plate 40 is connected to the bottom of the conveying mechanism 30, and a dual-stage filter cartridge 50 is inserted into the bottom of the connecting plate 40. A locking member 60 is also installed on the top of the connecting plate 40, and the locking member 60 is inserted into the dual-stage filter cartridge 50. Specifically, centrifugal separation and purification are required in the food additive production process. The conveying mechanism 30 is connected to an existing conveying device, and the connecting plate 40 is installed at the bottom of the conveying mechanism 30. 0. A dual-stage filter cartridge 50 is installed at the bottom of the connecting plate 40 to convey raw materials to the connecting plate 40 via the conveying mechanism 30. At the same time, the conveying mechanism 30 can drive the connecting plate 40 to rotate at high speed to achieve solid-liquid centrifugal separation. When the dual-stage filter cartridge 50 needs to be cleaned regularly, the cover plate 20 can be removed and the locking part 60 can be released from the fixation of the dual-stage filter cartridge 50. A lifting ring is fixedly installed on the top of the cover plate 20 so that the lifting device can lift the cover plate 20. Furthermore, the cover plate 20 is connected to the machine body 10 through the existing bolt structure.

[0025] See Figure 1-4The conveying mechanism 30 includes a conveying pipe 310 that rotatably passes through the cover plate 20. The top of the conveying pipe 310 is rotatably connected to a conduit 320. A positioning plate 330 is connected between the conduit 320 and the top of the cover plate 20. A connecting plate 40 is fixedly sleeved on the bottom of the outer wall of the conveying pipe 310. When installed, the conduit 320 is connected to the existing raw material conveying device. Its specific connection structure is existing technology. The positioning plate 330 achieves the purpose of limiting the conduit 320 so that the conduit 320 will not rotate.

[0026] See Figure 3 The conveying mechanism 30 also includes a motor 340 mounted on the top of the cover plate 20. The motor 340 drives the conveying pipe 310. In a specific configuration, the drive shaft of the motor 340 is equipped with a first bevel gear, while a second bevel gear is fixedly sleeved on the conveying pipe 310. The first bevel gear and the second bevel gear are meshed together so that the motor 340 drives the conveying pipe 310 to rotate.

[0027] See Figure 4 and 6 The dual-stage filter cartridge 50 includes a first filter cartridge 510 and a second filter cartridge 520. The first filter cartridge 510 is located inside the second filter cartridge 520. Both the first filter cartridge 510 and the second filter cartridge 520 are fixedly connected to the top of a connecting ring 530. The two connecting rings 530 are in contact with the bottom of the connecting plate 40. It should be noted that the filtration aperture of the first filter cartridge 510 is larger than that of the second filter cartridge 520, so as to separate solids of different sizes in the first filter cartridge 510 and the second filter cartridge 520 for centrifugal separation to improve centrifugation efficiency.

[0028] See Figure 5 and 6 Two positioning blocks 540 are fixedly connected to the top of each of the two connecting rings 530. The four positioning blocks 540 slide through the connecting plate 40. The same insert block 550 slides through between two adjacent positioning blocks 540. The insert block 550 is locked with the locking member 60. Specifically, four through holes are opened on the cover plate 20. The four positioning blocks 540 pass through the four through holes respectively. At the same time, through openings are opened on the positioning blocks 540. The insert block 550 passes through the through openings.

[0029] See Figure 5The locking component 60 includes an arc-shaped block 610 fixedly installed on the top of the connecting plate 40. Arc-shaped grooves 620 are provided on both ends of the side walls of the arc-shaped block 610. Arc-shaped rods 630 are slidably arranged in both arc-shaped grooves 620. A spring 640 is connected between the arc-shaped rods 630 and the side walls of the arc-shaped grooves 620. The two arc-shaped rods 630 are respectively inserted into the two insert blocks 550. It should be noted that a through hole is provided on the insert block 550 so that the arc-shaped rods 630 can pass through the through hole, thereby achieving the purpose of limiting the position of the insert block 550. Pushing the arc-shaped rods 630 can make the arc-shaped rods 630 slide into the arc-shaped grooves 620 to compress the spring 640, and at the same time facilitate the installation of the insert blocks 550. After the insert blocks 550 are positioned, the arc-shaped rods 630 are released, and the arc-shaped rods 630 move towards the insert blocks 550 via the spring 640 to pass through the insert blocks 550.

[0030] See Figure 4 and 7 The bottom of the machine body 10 is connected by a discharge pipe 110. The bottoms of the first filter cylinder 510 and the second filter cylinder 520 are both fitted onto the discharge pipe 110. In the specific configuration, the bottoms of the first filter cylinder 510 and the second filter cylinder 520 are funnel-shaped. The bottom of the first filter cylinder 510 corresponds to the top opening of the discharge pipe 110. At the same time, several through holes are opened on the side wall of the discharge pipe 110 so that the inside of the second filter cylinder 520 corresponds to the through holes, so that solids can be discharged through the discharge pipe 110. Furthermore, for solid substances adsorbed inside the first filter cylinder 510 and the second filter cylinder 520, the first filter cylinder 510 and the second filter cylinder 520 can be disassembled and cleaned.

[0031] See Figure 7 A sealing tube 120 is inserted inside the discharge pipe 110. It should be noted that during the centrifugation process, the sealing tube 120 is used to seal the discharge pipe 110. At the same time, a nut is installed at the bottom of the sealing tube 120, and the nut is threaded onto the bottom of the discharge pipe 110. Furthermore, a drain pipe is connected to the bottom of the outer wall of the machine body 10. An existing valve (not shown in the figure) is installed on the drain pipe to drain the liquid inside the machine body 10.

[0032] When this centrifuge for separating and purifying food additives is in operation: raw materials are conveyed to the dual-stage filter cartridges 50 inside the machine body 10 through the conduit 320 and the conveying pipe 310. At the same time, the motor 340 is started, which drives the conveying pipe 310 to rotate. The conveying pipe 310 drives the connecting plate 40 to rotate, and the connecting plate 40 drives the dual-stage filter cartridges 50 to rotate, thereby achieving the purpose of solid-liquid centrifugal separation. Under the centrifugal action, the solid matter will remain on the inner walls of the first filter cartridge 510 and the second filter cartridge 520, while the liquid will pass through the first filter cartridge 510 and the second filter cartridge 520 into the bottom of the machine body 10 and be discharged through the drain pipe, thus completing the solid-liquid separation. When cleaning the solid matter, it is taken out from the discharge pipe 110 through the sealing pipe 120, so that some solid matter is removed from the discharge pipe 110. When a lot of solid matter is adsorbed on the inner walls of the first filter cartridge 510 and the second filter cartridge 520, the first filter cartridge 510 and the second filter cartridge 520 can be removed for periodic cleaning.

[0033] It should be noted that the specific model and specifications of the body 10 and motor 340 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0034] The power supply and principle of the body 10 and the motor 340 are clear to those skilled in the art and will not be described in detail here.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
