Description

Technical Field

[0001] The present disclosure relates to the fields of food and chemical industry, and in particular, to a differential separator. Background Art

[0002] When soybeans are used as food raw materials for food processing, the soybeans usually need to be peeled. After peeling, the soybeans become bean kernels and bean skins. Therefore, the bean kernels and bean skins need to be further separated for subsequent processing.

[0003] In the prior art, a centrifugal separator is usually used to separate the two materials. Since the densities of bean kernels and bean husks are similar, when a centrifugal separator is used to separate bean husks and bean kernels, the separation efficiency is low and the separation effect is poor. Summary of the invention

[0004] The purpose of the present invention is to provide a differential separator, which can solve the technical problems of low separation efficiency and poor separation effect when separating bean husks and bean kernels.

[0005] In order to achieve the above-mentioned purpose, the present disclosure provides a differential separator for separating flakes and particulates with similar density, the differential separator comprising a shell having a cavity, the shell being provided with: an inlet for feeding a mixture of the flakes and the particulates into the cavity; a liquid injection port for injecting liquid into the cavity; and a first discharge port and a second discharge port, the first discharge port and the second discharge port being sequentially arranged along the flow direction of the liquid, the liquid driving the mixture to flow in the cavity, flushing out the particulates through the first discharge port, and flushing out the flakes through the second discharge port.

[0006] Optionally, the first discharge port is arranged below the liquid injection port.

[0007] Optionally, the liquid injection port is arranged below the feed port.

[0008] Optionally, the shell is also provided with an overflow port.

[0009] Optionally, the overflow port is arranged above the injection port.

[0010] Optionally, the shell is constructed as a U-shaped structure, the top of the U-shaped structure includes a first end and a second end relative to each other, the feed port and the liquid injection port are arranged at the first end, the second feed port is arranged at the second end, and the first feed port is arranged at the bottom of the U-shaped structure.

[0011] Optionally, the second end is formed with a downwardly bent extension section, and the second discharge port is opened at the bottom of the extension section.

[0012] Optionally, a transparent observation window is provided on the shell.

[0013] Optionally, the observation window is arranged between the first discharge port and the second discharge port.

[0014] Optionally, the differential separator comprises a breather for stabilizing the pressure within the cavity.

[0015] Through the above technical scheme, the differential separator provided by the present disclosure includes a shell with a cavity, and the shell is provided with an inlet, a liquid injection port, a first discharge port and a second discharge port. The mixed material composed of the flakes and the granules can be put into the cavity through the inlet, and the liquid can be injected into the cavity through the liquid injection port. The first discharge port and the second discharge port are arranged in sequence along the flow direction of the liquid. Under the impact of the liquid, the flakes and the granules can flow with the liquid. Since the force-bearing area of ​​the flakes is large and the force-bearing area of ​​the granules is small, the granules are not easily carried away by the liquid, and the flakes are easy to flow with the liquid. When the liquid drives the mixed material to flow to the first discharge port, the granules flow out from the first discharge port with a part of the liquid, and the flakes flow toward the second discharge port with another part of the liquid and are flushed out from the second discharge port. The differential separator provided by the present disclosure separates the mixed material by utilizing the different impacts on the flakes and the granules in the liquid. The separation of the granules and flakes in the mixed material is more thorough, the separation effect is good, and the separation efficiency is high.

[0016] Other features and advantages of the present disclosure will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0024] In the present disclosure, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the differential separator provided by the present disclosure in a normal use state, and "inner" and "outer" refer to the inner and outer parts relative to the contours of the corresponding parts themselves; the terms used, such as "first" and "second", etc., are used to distinguish one element from another, and do not have order and importance. In addition, when the following description refers to the drawings, the same mark in different drawings represents the same element.

[0025] According to a specific embodiment of the present disclosure, a differential separator is provided for separating flakes and particulates with similar density, for example, for separating soybean hulls and bean kernels produced after a soybean peeling process, the differential separator comprising a shell 1 having a cavity 11, the shell 1 being provided with: an inlet 2 for feeding a mixture of flakes and particulates into the cavity 11; a liquid injection port 3 for injecting liquid into the cavity 11; and a first discharge port 41 and a second discharge port 42, the first discharge port 41 and the second discharge port 42 being sequentially arranged along the flow direction of the liquid, the liquid driving the mixture to flow in the cavity 11, flushing out the particulates through the first discharge port 41, and flushing out the flakes through the second discharge port 42, reference Figures 1 to 3 As shown. The density of the flakes is similar to that of the granules, and can be close to that of the liquid, wherein the density of the granules and flakes can be slightly greater than that of the liquid. For example, the liquid in the specific embodiment of the present disclosure can be water, the liquid injection port 3 can be externally connected to a water pump, the feed port 2 can be externally connected to a soybean peeling machine, the flakes can be soybean skins, and the granules can be bean kernels, and the densities of soybean skins and bean kernels are both slightly greater than that of water. It should be noted that when using the differential separator provided in the present disclosure, the liquid used to separate the granules and flakes can be selected according to the densities of the flakes and the granules, so that the densities of the flakes and the granules are slightly greater than the density of the liquid, thereby ensuring the separation effect of the flakes and the granules.

[0026] Through the above technical scheme, the differential separator provided by the present invention includes a shell 1 with a cavity 11, and the shell 1 is provided with an inlet 2, an injection port 3, a first outlet 41 and a second outlet 42. A mixed material composed of flakes and particles can be put into the cavity 11 through the inlet 2, and liquid can be injected into the cavity 11 through the injection port 3. The first outlet 41 and the second outlet 42 are arranged in sequence along the flow direction of the liquid. Under the impact of the liquid, the flakes and particles can flow with the liquid. Since the force area of ​​the flakes is larger and the force area of ​​the particles is smaller, the particles are not easily carried away by the liquid and the flakes are easy to flow with the liquid. When the liquid drives the mixed material to flow to the first outlet 41, the particles flow out from the first outlet 41 with a part of the liquid, and the flakes flow toward the second outlet 42 with another part of the liquid and rush out from the second outlet 42. The differential separator provided by the present disclosure separates the mixed material by utilizing the different impact forces exerted on the flakes and the granules in the liquid. The separation of the granules and flakes in the mixed material is more thorough, the separation effect is good, and the separation efficiency is high.

[0027] In order to increase the impact force of the liquid at the first discharge port 41, the first discharge port 41 can be arranged below the liquid injection port 3 to utilize the gravity of the liquid to increase the impact force of the liquid at the first discharge port 41. Figure 1 and Figure 3 shown.

[0028] When the differential separator is working normally, the liquid level in the cavity 11 is not higher than the position of the injection port 3. When the cavity 11 is blocked, the liquid cannot flow out from the first discharge port 41 and the second discharge port 42. If the liquid continues to be injected into the cavity 11 through the injection port 3, the liquid level rises. In order to maintain the liquid level in the cavity 11, an overflow port 5 can also be provided on the housing 1. Figure 1 and Figure 3 As shown, the overflow port 5 can discharge excess liquid when blockage occurs in the cavity 11. In addition, the overflow port 5 also has a warning function. When the staff observes that the overflow port 5 overflows, they can promptly inspect and repair the differential separator to promptly check and clear the blockage point in the cavity 11.

[0029] In order to prevent leakage at the overflow port 5 when the differential separator is working normally, the overflow port 5 is arranged above the injection port 3. Figures 1 to 3 As shown, in addition, in order to prevent the liquid from flowing back at the feed port 2 when the cavity 11 is blocked, the overflow port 5 can be arranged below the feed port 2. That is to say, in the specific embodiment of the present disclosure, the overflow port 5 can be arranged between the injection port 3 and the feed port 2. In this way, the overflow port 5 can not only discharge the excess liquid in time, but also prevent the liquid from flowing back through the feed port 2 and damaging the equipment.

[0030] In the specific embodiments of the present disclosure, the housing 1 can be configured in any suitable manner. Figures 1 to 3 As shown, the shell 1 can be constructed as a U-shaped structure, and the top of the U-shaped structure includes a first end 12 and a second end 13 opposite to each other. The feed port 2 and the injection port 3 can be arranged at the first end 12, the second discharge port 42 can be arranged at the second end 13, and the first discharge port 41 can be arranged at the bottom of the U-shaped structure. Among them, the area between the feed port 2 and the injection port 3 is an injection section, and the mixed material and the liquid enter the first end 12 from the injection section; the area from the injection port 3 to the bottom of the first end 12 is a sedimentation section, and after the liquid is injected from the injection port 3, the mixed material is driven to settle in the sedimentation section under the action of gravity, and the speed direction is the same as the gravity direction. In order to prevent the mixed material from being discharged directly from directly below the first end 12 under the impact of the liquid and gravity, the first discharge port 41 can be arranged on one side of the bottom of the U-shaped structure close to the second end 13; the area directly below the first end 12 through the bottom of the U-shaped structure to directly below the second end 13 is a separation section. When the liquid and the mixed material flow to directly below the first end 12, the liquid and the mixed material are separated. The speed direction is downward. When the liquid and the mixed material flow through the bottom of the U-shaped structure to the bottom of the second end 13, the liquid begins to flow upward. At this time, the particles that are not easy to flow with the liquid gather below the second end 13, while the flakes that are easy to flow with the liquid flow upward with the liquid. The particles and flakes in the mixed material are separated in the separation section. The first discharge port 41 can be set below the second end 13. At this time, the particles can be discharged through the first discharge port 41 along with a part of the liquid; the floating section is from the bottom of the second end 13 to the second discharge port 42. In the floating section, the flakes flow upward with the liquid to the second discharge port 42 and are discharged. It should be noted that the shell 1 can be constructed in a variety of shapes. For example, the shell 1 can be constructed in an N-type structure or a ∽-type structure. As long as the structure of the shell 1 can make the cavity 11 have a material injection section, a sedimentation section, a separation section and a floating section, the present disclosure does not limit the specific structure of the shell 1.

[0031] In order to enable the second discharge port 42 to discharge the liquid and the sheet downward, the second end 13 may be formed with a downwardly bent extension section 131, and the second discharge port 42 is opened at the bottom of the extension section 131, so that the liquid drives the sheet downward. Figure 1 and Figure 3 shown.

[0032] In order to monitor the separation of the mixed materials in the cavity 11, the housing 1 may be provided with a transparent observation window 6. Figure 1 and Figure 3 As shown, if blockage occurs in the cavity 11 , the staff can find the blockage point in the cavity 11 through the observation window 6 .

[0033] The blockage in the cavity 11 generally occurs near the first discharge port 41 or near the second discharge port 42. Therefore, the observation window 6 can be arranged between the first discharge port 41 and the second discharge port 42. Figure 1 and Figure 3 As shown, in a specific embodiment of the present disclosure, two observation windows 6 can be provided on the shell 1, one of which is provided near the first discharge port 41 to observe the separation state of the particles and the flakes and the discharge of the particles, and the other observation window 6 can be provided between the first discharge port 41 and the second discharge port 42 to observe the discharge of the flakes.

[0034] During the production process, the differential separator needs to be CIP cleaned at regular intervals to prevent blockage in the cavity 11. When CIP cleaning is performed in the cavity 11, in order to prevent the pressure in the cavity 11 from changing dramatically due to alternating hot and cold air, a breather 7 for stabilizing the pressure in the cavity 11 is provided on the differential separator. The breather 7 is connected to the cavity 11. Figures 1 to 3 shown.

[0035] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0036] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0037] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
