Description

Technical Field

[0001] This utility model relates to the technical field of animal fat processing equipment, specifically a high-purity animal fat residue-liquid rapid separator. Background Technology

[0002] Animal fats are extracted from animals. Generally, the animal's fatty tissue is cleaned and broken into small pieces, then heated to rupture the fat cells and release the oil. The resulting mixture includes liquid oil, solid residue, and a small amount of water. The oil and residue must be separated to obtain the finished product.

[0003] During the separation process, there is a problem of oil residue clogging the filter structure. CN222877894U discloses an animal fat refining residue separation device that utilizes a rotating U-shaped rod to periodically squeeze an arc-shaped contact block, causing a striking plate to periodically move up and down, striking the surface of the separation filter cartridge. The vibration generated by this striking causes the oil residue to detach from the filter cartridge. By incorporating a spring, the swing range of the striking plate is increased, thereby improving the striking effect.

[0004] However, in practical applications, the rotation of the Z-shaped rotating rod is periodic, which causes the oscillation of the impact plate to also be periodic. In addition, the rotation speed of the filter cartridge is constant, which causes the impact plate to strike the same position on the filter cartridge. The position that is not struck will not have a good oil-sludge separation effect and will still clog the filter cartridge. Furthermore, repeated striking will cause deformation of the filter cartridge surface, which will cause changes in the filter pore size of the filter cartridge and affect the filtration quality.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0031] A high-purity animal fat residue rapid separation machine, comprising:

[0032] The filter box 1 includes a box body 11. A box cover 14 is rotatably mounted on the top surface of the box body 11 via a hinge. A spray assembly is provided on the top surface of the box cover 14. A central frame 2 is rotatably mounted in the middle of the box body 11. A filter assembly 3 is detachably mounted on the outer side of the middle of the central frame 2. The spray assembly can use liquid and gas to rinse the filter assembly 3.

[0033] The lid 14 is used to seal the top surface of the chamber 11 to prevent grease from flying out during filtration. It also ensures that the grease is not contaminated by external substances.

[0034] It should be noted that a locking device needs to be installed between the lid 14 and the body 11 during actual operation to prevent the lid 14 from being opened accidentally.

[0035] The box 11 is used to hold the filtered grease. One end of the box 11 is provided with a discharge chamber 12, and the bottom of the other end is provided with a discharge pipe 13.

[0036] The discharge hopper 12 is used to discharge solid materials, and the discharge pipe 13 is used to discharge liquid grease.

[0037] It should be noted that in actual production, a valve needs to be installed at point 13 of the discharge pipe to control the material discharge speed.

[0038] Temperature sensors, pressure sensors, and other detection instruments can also be installed at discharge pipe 13 to facilitate the detection of the oil's condition.

[0039] The spray assembly includes a spray pipe 15, which is axially arranged along the top surface of the box cover 14 and extends through the box cover 14 into the interior. One end of the spray pipe 15 is connected to a three-way valve 16, and the two inlets of the three-way valve 16 are respectively connected to an air source and a water source.

[0040] The air source can be a known air compressor to provide compressed air to the spray pipe 15.

[0041] The water source can be a combination of a known spray pump and a cleaning water tank, with the spray pump supplying high-pressure cleaning water to the spray pipe 15.

[0042] The three-way valve 16 is a solenoid valve with one outlet and two inlets. The outlet of the three-way valve 16 is threadedly connected to the head of the spray pipe 15. When the three-way valve 16 is working, the spray pipe 15 can be connected to any one of the feed pipes.

[0043] In the filtration state, the spray pipe 15 is connected to the air source, and compressed air is used to backwash the filter screen 33 to blow away the attached oil residue.

[0044] After filtration is complete, the spray pipe 15 is connected to the water source, and the filter screen 33 is cleaned using high-pressure water.

[0045] The central frame 2 includes a rotating shaft 21, with a power source 26 connected to the tail of the rotating shaft 21. The power source 26 is used to drive the rotating shaft 21 to rotate. The head of the rotating shaft 21 is provided with a feeding passage for materials to enter the filter assembly 3 from the feeding passage.

[0046] The rotating shaft 21 is axially rotatably mounted on the top surface of the housing 11.

[0047] The power source 26 uses a three-phase motor. The output shaft of the power source 26 is connected to the tail of the rotating shaft 21 through a known belt drive structure. When the power source 26 is working, it can drive the rotating shaft 21 to rotate.

[0048] A spiral plate 25 is welded to the outer side of the middle part of the rotating shaft 21.

[0049] When the rotating shaft 21 rotates, it can drive the spiral plate 25 to rotate. The spiral direction of the spiral plate 25 is the same as the rotation direction of the rotating shaft 21.

[0050] The feeding passage includes a feeding hole 22, which is located at the axis of the rotating shaft 21 and extends to the side of the power source 26. A discharge hole 23 is provided on the rotating shaft 21 and at the end of the feeding hole 22. A rotary joint 24 is provided at the end of the feeding hole 22, and the material is injected from the rotary joint 24.

[0051] The rotary joint 24 can maintain a seal with the shaft 21 when the shaft 21 rotates.

[0052] The material enters the feed hole 22 from the rotary joint 24 and then exits from the discharge hole 23, without being blocked by the spiral plate 25 and the box cover 14.

[0053] The filter assembly 3 includes several filter screens 33, which are axially arranged along the rotating shaft 21 and fixed on the rotating shaft 21 by a clamping structure.

[0054] Filter 33 uses a metal filter.

[0055] The inner diameter of filter screen 33 is the same as the outer diameter of spiral plate 25.

[0056] The inner side of the filter screen 33 abuts against the outer side of the spiral plate 25, which can prevent material from getting stuck between the spiral plate 25 and the filter screen 33. At the same time, the spiral plate 25 can support the filter screen 33.

[0057] The outer edge of the filter screen 33 is provided with a support plate 34, and the support plate 34 is provided with several slots 35 along the axial direction of the filter screen 33.

[0058] The support plate 34 can improve the axial pressure resistance of the filter screen 33 and prevent the filter screen 33 from deforming.

[0059] The clamping structure includes two clamping plates 31, which are axially slidably mounted on both ends of the rotating shaft 21 and engaged with the rotating shaft 21. Several clamping plates 32 are fixedly installed on the edges between the clamping plates 31 by bolts. The clamping plates 32 are inserted into the clamping slots 35, and the clamping plates 31 squeeze the filter screens 33 at both ends.

[0060] The clamping plate 31 near the head of the rotating shaft 21 is a solid metal plate, while the clamping plate 31 near the tail of the rotating shaft 21 has a hollow center.

[0061] Solid materials can be discharged from the hollowed-out clamping plate 31 at the tail of the rotating shaft 21 and enter the discharge bin 12.

[0062] The clamp 31 applies axial pressure to the filter screen 33, making the filter screen 33 stick together tightly. The clamping plate 32 is inserted into the clamping slot 35, which can prevent the filter screen 33 from rotating relative to the rotating shaft 21.

[0063] Loosening the bolts on the clamping plate 31 and the clamping plate 32 makes it easy to remove the clamping plate 32 and then remove the filter screen 33.

[0064] Working principle:

[0065] Close the box cover 14, control the power source 26 to work, and after the rotating shaft 21 reaches the predetermined speed, inject the material from the rotary joint 24.

[0066] The material enters the feed hole 22 from the rotary joint 24 and then rotates out from the discharge hole 23.

[0067] After the material is discharged, it falls onto the filter screen 33. Under the action of centrifugal force, the grease is filtered out, and the solid material moves towards the tail of the rotating shaft 21 under the push of the spiral plate 25. Finally, it is discharged from the hollowed-out clamping plate 31 at the tail of the rotating shaft 21 and falls into the discharge bin 12.

[0068] During the filtration process, the three-way valve 16 is controlled to connect the spray pipe 15 to the air source, and compressed air is used to backwash the filter screen 33 to blow away the attached oil residue.

[0069] After filtration is complete, keep the shaft 21 rotating. After the last grease is discharged through the discharge pipe 13, control the three-way valve 16 to connect the spray pipe 15 to the water source and use high-pressure water to clean the filter screen 33.

[0070] When it is necessary to replace the filter screen 33 with a different aperture, first open the box cover 14, loosen the bolts of the clamping plate 31 and the clamping plate 32, so that the clamping plate 32 can be easily removed, and then remove the filter screen 33.

[0071] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
