Description

Technical Field

[0001] This utility model belongs to the field of pear processing technology, and specifically relates to a deep processing filtration device for pears. Background Technology

[0002] Crisp pears are a popular fruit variety, loved by consumers at home and abroad for their smooth surface, large and plump size, juicy and crisp texture, rich nutrition and pollution-free nature. Crisp pears are often processed into crisp pear juice, which has medicinal value such as clearing heat and phlegm. When processing crisp pears, they are first crushed, and then the juice is further processed and filtered to completely separate the juice from the pulp.

[0003] To prevent filter cake from clogging the filter holes, existing filtration equipment usually requires disassembly and cleaning of the filter cartridge. This not only puts a certain amount of labor intensity on workers, but also makes continuous filtration impossible, affecting filtration efficiency.

[0004] Therefore, there is an urgent need for a deep-processing filtration device for crisp pears to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deep processing filtration device for crisp pears, comprising a storage component, a filtration component, and a cleaning component. The storage component includes a filtrate tank and a filter residue tank. The filtrate tank is fixedly installed, and the filter residue tank is fixedly installed on one side of the filtrate tank. The filtration component includes a filter cover and a filter cylinder. The filter cover is connected and fixedly mounted on the filtrate tank, and the filter cylinder is coaxially rotatably mounted inside the filter cover. The cleaning component includes a rotating cylinder, a suction pump, and a connecting pipe. The rotating cylinder is rotatably mounted inside the filter cylinder. Multiple cleaning brushes are provided on the outer periphery of the rotating cylinder, all used for cleaning the inner wall of the filter cylinder. Multiple cleaning holes are opened on the side wall of the rotating cylinder, and the multiple cleaning holes are distributed in the gaps between the multiple cleaning brushes. The suction pump is fixedly installed inside the filter residue tank. One end of the connecting pipe is sealed and connected to the suction pump, and the other end passes through the filter cylinder and is sealed and sleeved with the rotating cylinder.

[0006] As a further improvement of this utility model, a sealing plate is fixed at the upper end of the filter cover, and a T-shaped annular groove is opened at the lower end of the sealing plate. The upper end of the filter cylinder is configured as a T-shaped ring, and the filter cylinder is rotatably disposed in the T-shaped annular groove. A feed pipe is fixed through the center of the sealing plate, and multiple circumferentially distributed feed pipes are connected to the lower end of the feed pipe.

[0007] As a further improvement of this utility model, a funnel-shaped guide cylinder is fixed at the lower end of the filter cylinder, and a sealing block is sealed inside the lower end of the guide cylinder, with the connecting pipe passing through the sealing block.

[0008] As a further improvement of this utility model, it also includes a drive assembly, specifically a motor box, which is fixed to the sealing plate. A servo motor is fixed on the inner wall of the motor box, and a sleeve shaft is fixed to the output end of the servo motor. The sleeve shaft rotates through the sealing plate and is fixed to the upper end wall of the rotating drum.

[0009] As a further improvement of this utility model, it also includes a transmission component, specifically including a transmission gear set, a rotating shaft, a pinion, and a gear ring. The input end of the transmission gear set is fixed on the sleeve shaft, the rotating shaft is fixed on the output end of the transmission gear set, the pinion is fixed on the rotating shaft, and the gear ring is fixed on the outer peripheral wall of the filter cartridge. The pinion meshes with the gear ring.

[0010] As a further improvement of this utility model, a second suction pump is also fixedly installed inside the filter cake box, and a connecting hole is opened on the sealing block. A second connecting pipe is sealed and connected between the second suction pump and the connecting hole.

[0011] As a further improvement of this utility model, multiple columns are fixed at the lower end of the filtrate tank, and both the filtrate tank and the filter residue tank are connected to a discharge pipe for discharging the filtrate and filter residue.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By utilizing the cleaning components, during the centrifugal filtration process, the rotating drum drives the cleaning brush to rotate and clean the inner wall of the filter drum. During this process, the suction pump creates negative pressure inside the rotating drum, causing the filter residue attached to the cleaning brush to be sucked into the rotating drum through the cleaning holes and eventually into the filter residue box. Therefore, the cleaning brush is automatically and in real time cleaned through adsorption, avoiding the need for manual replacement of the filter drum periodically. At the same time, there is no need to replace the cleaning brush periodically, and the filtration process can be carried out continuously, thereby improving the filtration efficiency.

[0014] 2. By combining the drive and transmission components, a single motor can be used to drive the drum to rotate in the forward direction and indirectly drive the filter cartridge to rotate in the reverse direction, thereby reducing investment costs and improving practicality.

[0015] 3. A second suction pump and a second connecting pipe are installed. After filtration is completed, the second suction pump can completely remove the filter residue that has not been cleaned in the filter cartridge through the second connecting pipe, so that the filter cartridge does not need to be disassembled and cleaned, thus reducing the intensity of manual labor.

[0023] See Figures 1 to 6 As shown, a deep-processing filtration device for crisp pears includes a storage component, a filtration component, and a cleaning component. The storage component includes a filtrate tank 11 and a filter residue tank 12. The filtrate tank 11 is fixedly installed, and the filter residue tank 12 is fixedly installed on one side of the filtrate tank 11. The filtration component includes a filter cover 21 and a filter cylinder 22. The filter cover 21 is connected and fixed to the filtrate tank 11, and the filter cylinder 22 is coaxially rotatably disposed inside the filter cover 21. The cleaning component includes a rotating drum 31, a suction pump 32, and a connecting pipe 33. The rotating drum 31 is rotatably disposed inside the filter cylinder 22. Multiple cleaning brushes 311 are provided on the outer periphery of the rotating drum 31, all of which are used to clean the inner wall of the filter cylinder 22. Multiple cleaning holes 312 are opened on the side wall of the rotating drum 31, and the multiple cleaning holes 312 are distributed in the gaps between the multiple cleaning brushes 311. The suction pump 32 is fixedly installed inside the filter cake box 12. One end of the connecting pipe 33 is sealed and connected to the suction pump 32, and the other end passes through the filter cylinder 22 and is sealed and sleeved with the rotating drum 31.

[0024] Specifically, under the action of external force, when the filter cartridge 22 rotates clockwise for centrifugal filtration, the rotating drum 31 will rotate counterclockwise and drive multiple cleaning brushes 311 to clean the inner wall of the filter cartridge 22. During this period, the suction pump 32 creates negative pressure inside the rotating drum 31 through the connecting pipe 33, so that the filter residue attached to the cleaning brushes 311 will be sucked into the rotating drum 31 through multiple cleaning holes 312 and finally reach the filter residue box 12. Therefore, the cleaning brushes 311 are automatically and in real time cleaned through adsorption, avoiding the need for manual periodic replacement of the filter cartridge 22. At the same time, there is no need to periodically replace the cleaning brushes 311, and the filtration process can be carried out continuously, improving the filtration efficiency.

[0025] In a preferred embodiment, a sealing plate 41 is fixed at the upper end of the filter cover 21, and a T-shaped annular groove is provided at the lower end of the sealing plate 41. The upper end of the filter cylinder 22 is configured as a T-shaped ring, and the filter cylinder 22 is rotatably disposed in the T-shaped annular groove. A feed pipe 42 is fixed through the center of the sealing plate 41, and a plurality of circumferentially distributed feed pipes 43 are connected to the lower end of the feed pipe 42.

[0026] In other words, the filter cartridge 22 can rotate around the T-shaped groove when subjected to external force, thus achieving centrifugal filtration. Moreover, the feed pipe 43 guides the mixture to be filtered onto the inner wall of the filter cartridge 22, facilitating rapid filtration.

[0027] In a preferred embodiment, a funnel-shaped feed guide cylinder 44 is fixed at the lower end of the filter cylinder 22, and a sealing block 45 is sealed inside the lower end of the feed guide cylinder 44, and the connecting pipe 33 seals through the sealing block 45.

[0028] It should be explained that, firstly, the funnel-shaped feed tube 44 facilitates the collection and flow of unfiltered filter residue on the inner wall of the filter tube 22 into the sealing block 45. In addition, the sealing block 45 remains stationary relative to the filter tube 22, thereby avoiding interference from the connecting pipe 33 on the rotational movement of the filter tube 22. Moreover, the sealing block 45 can prevent filter residue from entering the filtrate tank 11.

[0029] In a preferred embodiment, a drive assembly is also included, specifically a motor housing 51, which is fixed on the sealing plate 41. A servo motor 52 is fixed on the inner wall of the motor housing 51, and a sleeve shaft 53 is fixed to the output end of the servo motor 52. The sleeve shaft 53 rotates through the sealing plate 41 and is fixed to the upper wall of the rotating drum 31.

[0030] In other words, when the servo motor 52 starts, it can drive the rotating drum 31 to rotate through the sleeve shaft 53, so that multiple cleaning brushes 311 can clean the inner wall of the filter cartridge 22.

[0031] In a preferred embodiment, a transmission assembly is also included, specifically including a transmission gear set 61, a rotating shaft 62, a pinion 63, and a gear ring 64. The input end of the transmission gear set 61 is fixed on the sleeve shaft 53, the rotating shaft 62 is fixed on the output end of the transmission gear set 61, the pinion 63 is fixed on the rotating shaft 62, and the gear ring 64 is fixed on the outer peripheral wall of the filter cartridge 22. The pinion 63 meshes with the gear ring 64.

[0032] Specifically, for example, please refer to Figure 6 When the servo motor 52 drives the drum 31 to rotate in the forward direction, it can also drive the transmission gear set 61 to mesh and drive, thereby driving the rotating shaft 62 to rotate in the forward direction. The rotating shaft 62 drives the pinion 63 to rotate synchronously. After the pinion 63 meshes with the gear ring 64, the filter cartridge 22 achieves reverse rotation. Therefore, the cleaning brush 311 on the drum 31 will thoroughly clean the inner wall of the filter cartridge 22.

[0033] As can be seen from the above, this utility model uses only one servo motor 52, which can drive the rotating drum 31 to rotate in the forward direction on the one hand, and indirectly drive the filter cartridge 22 to rotate in the reverse direction on the other hand, thereby reducing investment costs and improving practicality.

[0034] In a preferred embodiment, a second suction pump 71 is also fixedly installed inside the filter cake box 12, and a connecting hole is provided on the sealing block 45. A second connecting pipe 72 is sealed and connected between the second suction pump 71 and the connecting hole.

[0035] In other words, the filter residue on the inner wall of the filter cartridge 22 that has not been cleaned by the cleaning brush 311 flows into the area of ​​the guide cylinder 44 above the sealing block 45 under its own gravity. After filtration is completed, the suction pump 71 is started, and the filter residue in this area will enter the filter residue box 12 through the connecting pipe 72.

[0036] In a preferred embodiment, the lower end of the filtrate tank 11 is fixed with multiple columns 111, and both the filtrate tank 11 and the filter residue tank 12 are connected to discharge pipes for discharging filtrate and filter residue.

[0037] Specifically, when deep processing and filtration of pears is required, the servo motor 52 and the suction pump 32 are started simultaneously. The filter cartridge 22 rotates to generate centrifugal filtration. During this process, the rotating drum 31 rotates, and the cleaning brush 311 cleans the unfiltered filter residue on the inner wall of the filter cartridge 22. The filter residue attached to the cleaning brush 311 enters the rotating drum 31 under negative pressure, and then enters the filter residue box 12 through the connecting pipe 33. During this process, the cleaning brush 311 can automatically clean itself. The filtrate enters the filtrate box 11, achieving separation of the filter residue and filtrate. After filtration is completed, the servo motor 52 and the suction pump 32 are turned off, and the suction pump 71 is turned on. The suction pump 71 will completely suck the uncleaned filter residue in the filter cartridge 22 into the filter residue box 12 through the connecting pipe 72.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
