Description

Technical Field

[0001] This utility model relates to the field of dairy equipment technology, specifically a defatting separator. Background Technology

[0002] Disc separators are key equipment in the dairy industry for defatting and impurity separation. They use a high-speed rotating array of discs to create a centrifugal force field, causing components of different densities in milk to separate into strata along the gaps between the discs. The design of disc separators is based on the physical properties of standard milk, and the disc spacing is usually fixed, preset by the manufacturer to 0.3~1.0 mm using spacers, to balance separation efficiency and throughput.

[0003] However, in actual production, the quality of raw milk is affected by factors such as pasture environment, storage conditions, and pretreatment processes. It is often mixed with large, irregularly shaped impurities such as hair, sand, and feed residue, or colloidal aggregates formed by microbial action. When milk with such high impurity content enters the narrow gap between the discs, it is prone to physical blockage and dirt adhesion problems. The blockage directly leads to a significant decrease in separation efficiency, manifested as excessive residual fat content in skim milk and cross-contamination between light and heavy phases. At the same time, local flow field turbulence can induce increased equipment vibration, abnormal bearing wear, and even trigger safety shutdowns, forcing production to be interrupted for frequent manual cleaning. Therefore, a skim milk separator is proposed to solve the above problems. Utility Model Content

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] like Figure 1-6 As shown, a defatting separator in this embodiment includes a separator body 1 and a filter device 2. The filter device 2 is installed at the feed inlet of the separator body 1 and is used to pre-filter the milk entering the separator body 1, thereby reducing impurities entering the separator body 1.

[0032] The filter device 2 includes an integrally formed filter chamber 20, a collection chamber 21, and a discharge pipe 22. The top of the filter chamber 20 is open. The collection chamber 21 is located at the bottom of the filter chamber 20 and is conical, which facilitates the concentration and guidance of milk to the bottom of the collection chamber 21. The discharge pipe 22 is located at the bottom of the filter chamber 20 and its bottom end is connected to the feed inlet of the separator body 1, specifically through a flange.

[0033] The filter chamber 20 is equipped with a multi-stage filter section 23 for filtration. It is movably installed in the filter chamber 20 through an opening at the top of the filter chamber 20. It can be lifted out of the filter chamber 20 for cleaning. Specifically, it includes a bottom plate 230 and a top plate 234. A first annular screen 231 and a second annular screen 232 are arranged between the bottom plate 230 and the top plate 234. The first annular screen 231 is located in the second annular screen 232. A discharge screen cylinder 233 is arranged outside the bottom plate 230 and located below the top plate 234. The outer diameter of the discharge screen cylinder 233 is smaller than the inner diameter of the filter chamber 20. A central hole with the same diameter as the inner diameter of the first annular screen 231 is provided at the center of the top plate 234, and its outer diameter is adapted to the outer diameter of the filter chamber 20.

[0034] It should be noted that the mesh counts of the first annular screen 231, the second annular screen 232, and the discharge screen cylinder 233 decrease sequentially.

[0035] With this design, milk can be introduced into the first annular screen 231 through the central hole of the top plate 234, thereby achieving multi-stage filtration by using the first annular screen 231, the second annular screen 232 and the discharge screen cylinder 233. At the same time, since the outer diameter of the discharge screen cylinder 233 is smaller than the inner diameter of the filter chamber 20, it is convenient to discharge the milk from multiple directions through the side wall and bottom wall of the discharge screen cylinder 233, thereby improving the discharge efficiency.

[0036] In a preferred embodiment, cavities are provided between the discharge screen cylinder 233 and the second annular screen 232, and between the second annular screen 232 and the first annular screen 231, thereby effectively improving the material storage capacity of the filtration device 2 in each stage of filtration.

[0037] In a preferred embodiment, the top of the top plate 234 is provided with two mounting handles 235, which are symmetrically arranged on the top of the top plate 234, thereby facilitating the installation and removal of the filter device 2 via the mounting handles 235.

[0038] In a preferred embodiment, the inner wall of the filter chamber 20 is provided with a plurality of mounting grooves 201, and the outer side of the discharge screen cylinder 233 is provided with mounting blocks 236 that are adapted to the mounting grooves 201. In this embodiment, there are two mounting grooves 201 and two mounting blocks 236, which are symmetrically arranged. Through the cooperation of the mounting grooves 201 and the mounting blocks 236, unnecessary rotation of the multi-stage filtration section 23 can be prevented during use.

[0039] In another embodiment, a switch control unit 24 for controlling the opening and closing of the discharge pipe 22 is provided through the center of the base plate 230. The discharge pipe 22 can be temporarily closed by the switch control unit 24, and opened after filtering enough milk, thereby ensuring the smooth flow of the feed.

[0040] The switch control unit 24 includes an outer tube 240 that passes through the center of the base plate 230. Both the upper and lower ends of the outer tube 240 are open, and its top extends above the center hole of the top plate 234. Its bottom can close the discharge pipe 22. Two switch ports 242 are symmetrically arranged on the side wall at the bottom of the outer tube 240. A telescopic rod 243 is telescopically inserted into the inside of the outer tube 240. The bottom end of the telescopic rod 243 is provided with a spring switch part 245 that can cooperate with the switch port 242, and the top end is provided with a control handle 248. The switch port 242 is opened and closed by the spring switch part 245. The filtered milk enters the discharge pipe 22 through the open switch port 242.

[0041] In a preferred embodiment, the elastic switch part 245 includes a telescopic cavity 2450 disposed at the bottom end of the telescopic rod 243. Both ends of the telescopic cavity 2450 are open. Limiting grooves 2451 are symmetrically arranged on the upper and lower sides of the telescopic cavity 2450. Both ports of the telescopic cavity 2450 are provided with retractable closing blocks 2452. The closing blocks 2452 can be inserted into the corresponding switch ports 242 to close them. Limiting blocks 2453 are provided at both the upper and lower ends of the two closing blocks 2452. The limiting blocks 2453 are slidably connected to the corresponding limiting grooves 2451. A telescopic spring 2454 is provided between the two closing blocks 2452. The top of the closing blocks 2452 and the switch ports 242 are provided with matching ramp surfaces 2555.

[0042] With this design, the two sealing blocks 2452 can remain open under the tension of the telescopic spring 2454, thus maintaining their insertion into the corresponding switch port 242, thereby achieving the effect of sealing the bottom outlet of the collection chamber 21. In addition, when the telescopic rod 243 is lifted upward by controlling the handle 248, the slope surface 2555 between the sealing block 2452 and the switch port 242 can be used to make the sealing block 2452 retract during the upward process, thereby opening the switch port 242. Furthermore, the friction between the sealing block 2452 and the inner wall surface of the outer sleeve 240 provides a temporary fixing effect.

[0043] In a preferred embodiment, the inner wall of the outer sleeve 240 is provided with a plurality of telescopic grooves 246, and the outside of the telescopic rod 243 is provided with a telescopic block 247 that slides with the telescopic grooves 246. In this embodiment, there are two telescopic grooves 246 and two telescopic blocks 247. Through the cooperation of the two, the telescopic height of the telescopic rod 243 can be limited.

[0044] In a preferred embodiment, a fitting groove 210 is provided on the inner wall surface at the bottom of the collecting chamber 21, and a fitting plate 241 adapted to the fitting groove 210 is provided on the outer wall surface at the bottom end of the outer sleeve 240. The fitting between the fitting groove 210 and the fitting plate 241 can improve the sealing effect on the discharge pipe 22.

[0045] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
