Description

Technical Field

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

[0002] Plant-based beverages refer to beverage products made from plants or plant extracts through processing or fermentation. The plant is generally tea as the main ingredient. Tea is generally processed into tea beverages, which are tea leaves soaked in water and made into tea soup through multiple processes such as extraction, filtration, and clarification. When producing tea beverages, an essential step is centrifugal separation, which allows the tea leaves and liquid in the tea beverage to be quickly separated for subsequent processing and use.

[0003] Under normal use, centrifugal separation equipment is difficult to avoid the problem of clogging due to long-term filter cartridges. Therefore, some centrifugal equipment usually adds a dredging structure, that is, using components such as a thimble to touch the filter holes on the filter cartridge to make the tea leaves blocked in the through holes fall off. However, in actual use, the filter holes are arranged around the side walls of the filter cartridge and are extremely small. Therefore, it is difficult to ensure that the thimble is always aligned with the filter holes. At the same time, the thimble method cannot achieve a complete dredging effect, and can only make some tea leaves close to the filter holes away from the through holes. Its dredging efficiency is also very low. Utility Model Content

[0004] Based on the above description, the utility model provides a centrifugal filtering device to solve the shortcomings of the existing centrifugal separation equipment that uses a top-contact method for dredging, which has a poor dredging effect and very low efficiency.

DETAILED DESCRIPTION

[0021] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0023] Combination Figure 1-4 As shown, a centrifugal filter device comprises:

[0024] The outer cylinder 1 is the outer shell of the entire centrifugal device, and its top is open and provided with a top cover 11, and the top cover 11 can be sealed and connected to the top of the outer cylinder 1;

[0025] The inner cylinder 2 is the core component of the entire centrifugal device. A large number of filter holes are provided on the side wall for separating tea leaves and water, and the inner cylinder 2 is movably coupled with the outer cylinder 1.

[0026] The mounting plate 3 is arranged below the opening of the outer cylinder 1 and is mainly used to fix and support the inner cylinder 2;

[0027] The dredging components 4 are respectively installed on the top and bottom of the inner cylinder 2 to act as a buffer structure and simultaneously play a supporting and fixing effect.

[0028] Specifically, in the present embodiment, the mounting plate 3 and the driving disk 31 are arranged as an annular structure and are arranged concentrically, and a ball bearing is used for movable equipment between the two, so that the driving disk 31 can rotate flexibly. At the same time, in order to ensure the sealing of the equipment, a sealing ring should be used for sealing at the connection between the two.

[0029] The dredging assembly 4 includes an upper connecting seat and a lower connecting seat fixedly installed on the top and bottom of the inner cylinder 2, wherein the lower connecting seat is smaller and can freely pass through the central hole of the driving disk 31, so that the entire inner cylinder 2 extends vertically downward and fits against the inner bottom surface of the outer cylinder 1, and at this time the upper connecting seat 41 just fits against the surface of the driving disk 31, thereby relying on the upper and lower fixed structures of the driving disk 31 and the outer cylinder 1 to form support to ensure the stability of the inner cylinder 2.

[0030] At the same time, a support portion 44 is provided at the bottom of the lower connecting seat 42. The support portion 44 is cylindrical, and a bearing seat structure should be additionally arranged on its bottom surface. The bearing seat is locked and fixed to the bottom surface of the outer cylinder 1 by bolts or a structure assembled by thread. A drive motor 13 is provided at the center of the inner bottom surface of the outer cylinder 1. The drive motor 13 is arranged vertically upward and is covered by the support portion 44. The output end of the drive motor 13 extends vertically upward and is fixedly connected to the center of the bottom surface of the inner cylinder 2, thereby providing a power source for the centrifugal work of the inner cylinder 2.

[0031] A plurality of slots 32 are vertically arranged on the inner ring surface of the driving disk 31, so that its shape is similar to a spline hole structure, and a plug plate 43 partially protrudes downward on the bottom surface of the upper connecting seat 41, and the plug plate 43 is exactly adapted to the slot 32, and the two are plugged and fixed to each other. Therefore, when the driving motor 13 at the bottom drives the inner cylinder 2 to rotate at high speed, the upper connecting seat 41 and the lower connecting seat 42 can rotate with it without causing any obstruction.

[0032] At the same time, in order to further strengthen the fixing effect between the drive disk 31 and the upper connecting seat 41, bolt holes should be set at the bottom of the slot 32 and the inside of the plug plate 43, and bolts should be used to lock them so that the upper connecting seat 41 and the drive disk 31 are connected as a whole.

[0033] In addition, a vibration motor 45 is provided at the bottom or top of the inner cylinder 2. The vibration motor 45 is the core component of the dredging assembly 4. Its purpose is to shake the side wall of the inner cylinder 2 by vibration, so that the tea residues attached to its inner wall and blocked inside the filter hole fall off, thereby completing the dredging. Therefore, in order to avoid collision due to vibration, a buffer 46 should be provided at the connection between the upper connecting seat 41 and the lower connecting seat 42 and the inner cylinder 2. The buffer 46 can be a damping spring or an annularly arranged air spring, so that the vibration of the inner cylinder 2 will be absorbed and blocked by the buffer 46.

[0034] In actual use, in order to facilitate the addition of tea, a through hole should be set at the center of the top surface of the top cover 11, and an electronic valve 12 should be set inside. The top of the electronic valve 12 extends upward to communicate with the external water inlet pipe, and the bottom of the electronic valve 12 extends downward and passes through the upper connecting seat 41 to extend to the interior of the inner cylinder 2. The staff can add tea by controlling the opening and closing of the electronic valve 12. The bottom side wall of the outer cylinder 1 is also provided with a drain pipe for discharging filtered tea.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
