Description

Technical Field

[0001] This utility model relates to the technical field of dairy processing equipment, and specifically discloses a filtration device for dairy processing. Background Technology

[0002] In dairy processing, filtration is a crucial step in removing impurities from raw milk and ensuring product quality. Existing technology, such as the patent application CN217988605U entitled "A Filtration and Impurity Removal Device for Dairy Processing," discloses a device that uses a double-layer filter barrel for centrifugal filtration. However, in practical applications, this device suffers from the following drawbacks, making it difficult to meet the demands of high-efficiency production:

[0003] The existing device has a fixed-installation structure for the impurity removal box. After filtration, the box cover must be opened and the filter components disassembled before the impurity removal disc can be removed to clean the filter residue. The operation steps are cumbersome and can easily cause secondary pollution. At the same time, the bottom of the impurity removal box is a flat structure without an inclined liquid collection design, making it difficult to completely drain the residual filtrate after filtration, which affects the hygiene of subsequent processing.

[0004] The existing device has a fixed connection between the first and second filter barrels. There is no precise positioning structure during disassembly and assembly, which can easily cause axial displacement and lead to leakage of raw milk. In addition, the pore diameter of the two filter barrels is fixed and cannot be replaced individually. It is impossible to flexibly adjust the filtration level according to the filtration precision requirements of different dairy products such as pasteurized milk and cream, which limits the scope of application.

[0005] To address the aforementioned issues, this invention employs a collaborative structure combining a flip-up processing cylinder and a rotating filter cylinder, along with a double-layered, detachable, and positionable filter assembly. This approach aims to overcome the shortcomings of existing technologies and improve filtration efficiency and ease of operation. Utility Model Content

[0006] This utility model proposes a filtration device for dairy processing. Through a dual-drive flipping and rotating structure, a graded positioning filter cartridge, and a synchronous sterilization design, it achieves convenient operation, precise filtration, hygiene and safety, and improved efficiency, solving the problems of cumbersome cleaning, poor adaptability, and significant hygiene risks of existing dairy filtration devices.

[0007] This utility model is implemented as follows: a filtration device for dairy processing includes a U-shaped support and a processing cylinder. The processing cylinder is rotatably mounted inside the U-shaped support via a rotating shaft.

A rotary motor is located on the outer side of the bottom of the processing cylinder, and the output end of the rotary motor is coaxially and fixedly connected to the rotating seat via a drive shaft. A cylinder cover is threaded to the port of the processing cylinder, and the cylinder cover has a feeding port. The U-shaped support is equipped with a worm gear mechanism for driving the processing cylinder to rotate around the rotating shaft. A conical collection groove is formed at the bottom of the inside of the processing cylinder.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Please see Figure 1-4 A filtration device for dairy processing includes a U-shaped support 1 and a processing cylinder 2. The processing cylinder 2 is rotatably mounted inside the U-shaped support 1 via a rotating shaft 3. The processing cylinder 2 is equipped with a processing mechanism, which includes a rotating seat 4 and a filter cylinder 5 detachably mounted on the top of the rotating seat 4. A rotary motor 6 is provided on the outer side of the bottom of the processing cylinder 2, and the output end of the rotary motor 6 is coaxially fixedly connected to the rotating seat 4 via a drive shaft 7. A cylinder cover 8 is threadedly connected to the port of the processing cylinder 2, and a feeding port 9 is provided on the cylinder cover 8. The U-shaped support 1 is equipped with a worm gear mechanism for driving the processing cylinder 2 to rotate around the rotating shaft 3. A conical collection groove 10 is provided at the bottom of the inside of the processing cylinder 2. A drain pipe 11 communicating with the conical collection groove 10 is provided at the bottom of the processing cylinder 2, and a first control valve 12 is provided on the drain pipe 11.

[0028] In this embodiment: dairy raw materials are continuously or in batches fed into the high-speed rotating filter cylinder 5 through the feeding port 9 of the cylinder cover 8. Under the action of centrifugal force, the liquid passes through the mesh of the filter cylinder 5 and is thrown out, while impurities are trapped inside the filter cylinder 5, thereby achieving solid-liquid separation. The thrown-out liquid impacts the inner wall of the processing cylinder 2, which can also rotate around the horizontal axis, and flows into the conical collection tank 10 at the bottom, and is finally discharged through the drain pipe 11. After filtration is completed, the drive motor 15 can be started to rotate the entire processing cylinder 2 on the U-shaped support 1 via the worm gear mechanism. The filter cylinder 5 is rotated inside to completely drain residual liquid or pour out filter residue. When cleaning is required, there is no need to disassemble the filter cylinder 5. Simply introduce cleaning liquid or clean water into the annular pipe 16 through the water inlet 19. The cleaning liquid will then spray out from the staggered flushing holes 18 to automatically flush the inside and outside of the high-speed rotating filter cylinder 5 without dead angles. In addition, during the entire process, the ultraviolet germicidal lamp 27 at the bottom of the cylinder cover 8 can continuously sterilize the feeding port 9 area, while the internal working status can be monitored in real time through the transparent observation window 28 on the processing cylinder 2.

[0029] It should be noted that the rotation speed of the rotary motor 6 is adjustable, ranging from 500 to 1500 r / min, to suit dairy products of different viscosities (e.g., 800-1000 r / min for pasteurized milk and 500-700 r / min for cream).

[0030] As a technical optimization of this utility model, the worm gear mechanism includes a worm wheel 13 coaxially and fixedly connected to the rotating shaft 3, a worm 14 meshing with the worm wheel 13, and a drive motor 15 disposed on the U-shaped support 1 and coaxially and fixedly connected to one end of the worm 14.

[0031] In this embodiment, the self-locking characteristics of the worm gear 13 and worm 14 are utilized to ensure that the processing cylinder 2 can be stably stopped at any angle, which facilitates slag discharge or observation and enhances the operability and safety of the equipment.

[0032] As a technical optimization of this utility model, the bottom of the cylinder cover 8 is inverted conical, with its cone tip facing the feeding port 9, which is used to guide the filter residue to gather towards the feeding port 9 during slag discharge.

[0033] In this embodiment: After filtration is completed, when the processing cylinder 2 is flipped by the worm gear mechanism to discharge slag, the residue or droplets attached to the inner wall of the cylinder cover 8 can be guided to the central feeding port 9 under the action of gravity along the inverted conical slope, so as to be discharged more concentratedly and thoroughly, effectively avoiding cleaning dead corners, and further improving the self-cleaning ability and hygiene standards of the equipment.

[0034] As a technical optimization of this utility model, an annular pipe 16 is provided on the upper part of the inner wall of the treatment cylinder 2, and at least two flushing pipes 17 are provided at the bottom of the annular pipe 16. Several flushing holes 18 are opened on the side of the flushing pipe 17 facing the filter cylinder 5. The flushing holes 18 are evenly distributed along the length of the flushing pipe 17, and the flushing holes 18 on the two flushing pipes 17 are staggered. A water inlet 19 is provided on the outer wall of the treatment cylinder 2. The water inlet 19 is connected to the annular pipe 16, and a second control valve 20 is provided on the water inlet 19.

[0035] In this embodiment: a water source is connected through the water inlet 19, and the second control valve 20 is opened (the water inlet 19 is connected to clean water with a pressure of 0.3-0.5MPa, and the rinsing time is 3-5 minutes). Without disassembling the filter cartridge 5, a thorough rinsing is achieved, ensuring that there is no filter residue on the inner and outer walls of the filter cartridge 5. The cleaning is simple and not easily contaminated.

[0036] As a technical optimization of this utility model, the filter cylinder 5 has a double-layer structure. The filter cylinder 5 includes an outer cylinder 21, an inner cylinder 22 sleeved inside the outer cylinder 21, and a sealing base 23 connecting the bottom of the outer cylinder 21 and the inner cylinder 22. The filter pore diameter of the outer cylinder 21 is smaller than that of the inner cylinder 22.

[0037] In this embodiment, a two-stage gradient filtration is achieved through the design of a double-layer filter cartridge 5 with different pore sizes. This allows users to replace the filter cartridge 5 with different pore sizes according to different products (such as pasteurized milk and cream), thus solving the problem of fixed filtration levels and limited applicability in the prior art.

[0038] As a technical optimization of this utility model, the outer wall of the outer cylinder 21 and the inner wall of the inner cylinder 22 are provided with a number of positioning sleeves 24 along the axial direction. Each positioning sleeve 24 is fitted with a positioning rod 25 that is fixedly connected to the top of the rotating seat 4. The outer wall of the positioning rod 25 is provided with a locking nut 26 that fits against the uppermost positioning sleeve 24.

[0039] In this embodiment, the precise axial / radial positioning of the filter cylinder 5 and the rotating seat 4 is achieved by using the positioning sleeve 24, the positioning rod 25, and the locking nut 26. The position is locked by the nut to prevent the filter cylinder 5 from shifting during rotation and causing raw material leakage. This solves the problem of the filter cylinder in the existing device having no positioning and being prone to shifting, and at the same time facilitates the disassembly and replacement of the filter cylinder 5.

[0040] As a technical optimization of this utility model, the bottom of the cylinder cover 8 is provided with an ultraviolet germicidal lamp 27.

[0041] In this embodiment, the ultraviolet germicidal lamp 27 can effectively prevent microbial contamination during processing, which is an important value-added innovation.

[0042] As a technical optimization of this utility model, the processing cylinder 2 is provided with a transparent observation window 28.

[0043] In this embodiment, the internal working condition can be monitored through the transparent observation window 28 without opening the cylinder cover 8, which facilitates timely adjustments to the operation (such as cleaning filter residue, starting and stopping rinsing) and improves the ease of operation.

[0044] Working principle and usage process of this utility model:

[0045] Based on the required filtration precision, select a suitable double-layer filter cylinder 5, align it with the rotating seat 4 using the positioning rod 25 and positioning sleeve 24, and tighten it with the locking nut 26; tighten the cylinder cover 8 to ensure the feeding port 9 is sealed; turn on the rotary motor 6 at the bottom of the processing cylinder 2 to drive the filter cylinder 5 to rotate at high speed; feed the raw milk into the feeding port 9 to begin centrifugal filtration, and discharge the filtrate through the conical collection tank 10 and the drain pipe 11; after filtration, turn off the rotary motor 6. Start the drive motor 15 of the worm gear mechanism to rotate the processing cylinder 2 at a certain angle to drain the residual filtrate inside the cylinder; if it is necessary to clean the filter residue, continue to rotate it until the opening is facing down to pour out the filter residue; reset the processing cylinder 2, connect the water source through the water inlet 19, open the second control valve 20, and at the same time start the filter cylinder 5 to rotate at low speed. The cleaning liquid is sprayed out from the staggered flushing holes 18 to thoroughly flush the filter cylinder 5; the entire process can be monitored through the transparent observation window 28; the ultraviolet germicidal lamp 27 works continuously during equipment operation.
