Description

Technical Field

[0001] This utility model relates to the technical field of animal fat processing equipment, specifically a solid-liquid separation filter press for removing cholesterol from animal fats. Background Technology

[0002] In the processing of animal fats, it is necessary to remove excess cholesterol from the fats. Currently, the most widely used and economical method for cholesterol removal in industry is physical adsorption. An adsorbent is added to the fat, which encapsulates cholesterol molecules, forming a water-insoluble solid complex. Then, equipment such as a filter press is used for solid-liquid separation, yielding fats containing low-grade cholesterol and filter residue containing a large amount of cholesterol and adsorbent. Plate and frame filter presses are commonly used in this process.

[0003] After one filtration cycle in a plate and frame filter press, the filter cake between the filter plates needs to be removed before filtration can proceed again. Currently, the mainstream automatic type is the plate and frame filter press, which typically uses a traveling mechanism to pull the filter plates apart one by one, relying on gravity and vibration during travel to cause the filter cake to fall off.

[0004] However, in actual use, the filter cake still contains some grease. After filtration, as the temperature drops, the grease becomes more viscous, and most of the filter cake falls off by gravity. Some of the filter cake near the top, due to the grease's viscosity, adheres to the filter plate surface and needs to be removed by operators using scrapers, affecting the overall operating efficiency of the filter press. During cleaning, the filter cloth may be scratched, introducing hygiene and safety risks. Utility Model Content

Detailed Implementation

[0015] 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.

[0016] Example 1: Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments: A solid-liquid separation filter press for cholesterol removal from animal fats includes: The frame 1, filter plate 2, and pressing mechanism 4 are provided. The filter plate 2 is slidably connected to the frame 1 via a slider 3. The frame 1 is provided with a walking mechanism 6 on both sides via a drive mechanism 5. The walking mechanism 6 is used to pull open the filter plate 2. A sweeping and blowing device is provided above the two walking mechanisms 6. The sweeping and blowing device is used to sweep and blow the top of both sides of the filter plate 2.

[0017] The pressing mechanism 4 is powered by a hydraulic cylinder and is used to press the filter plate 2.

[0018] The drive mechanism 5 uses a known motor and chain drive scheme to drive the reciprocating motion of the walking mechanism 6.

[0019] The walking mechanism 6 is used to hook the sliders 3 on both sides of the filter press plate 2, thereby pulling the filter press plate 2 apart and causing the filter cake to fall off.

[0020] When the traveling mechanism 6 pulls open the filter press plate 2, the relative position between the traveling mechanism 6 and the filter press plate 2 is fixed. Therefore, when the sweeping and blowing device sweeps and blows the filter press plate 2, the relative position between the sweeping and blowing device and the filter press plate 2 is fixed.

[0021] The purging device includes a mounting bracket, on the top of which a purging pipe 9 is rotatably mounted. The purging pipe 9 has an axially elongated air outlet 11 in the middle and is configured to allow compressed air to pass through it.

[0022] The purging pipe 9 has a threaded connection at one end to a hose connector 12, which is a quick-connect coupling used to connect to a compressed air source via a hose. The air source can be any known air compressor. The hose will not obstruct the movement of the purging device.

[0023] The elongated air outlet 11 can form an air knife, which can cover the entire area of ​​the top side of the filter press plate 2.

[0024] The mounting bracket includes a column 7, which is T-shaped. The top of the column 7 is symmetrically provided with mounting sleeves 8, and the sweeping pipe 9 is rotatably installed in the mounting sleeves 8.

[0025] The symmetrical arrangement on both sides allows for simultaneous sweeping and blowing of both sides of the filter plate 2, improving the efficiency and effectiveness of the sweeping and blowing cleaning process.

[0026] The mounting sleeve 8 is equipped with a locking screw 10, which is used to restrict the rotation of the sweeping pipe 9 when the locking screw 10 is tightened.

[0027] Loosening the locking screw 10 allows for easy adjustment of the angle of the sweeping pipe 9.

[0028] The end of the sweeping pipe 9 is fixedly installed with a limiting sleeve 14 by a fixing screw 15 on the outside of the mounting sleeve 8.

[0029] The limiting sleeve 14 is used to limit the axial movement of the sweeping pipe 9.

[0030] The limiting sleeve 14 is provided with an indicator scale 16, and the mounting sleeve 8 is provided with an indicator mark 17 on the side near the limiting sleeve 14.

[0031] The indicator mark 17, in conjunction with the indicator scale 16, can display the relative position of the air inlet 11 and the filter press plate 2.

[0032] During commissioning, it allows for convenient and precise adjustment of the sweeping angle of the sweeping pipe 9.

[0033] During disassembly and maintenance, the sweeping pipe 9 can be easily reassembled and reset.

[0034] The sweeping pipe 9 is provided with a limiting groove 13 at its end. The inner side of the limiting sleeve 14 is adapted to the limiting groove 13. The limiting groove 13 is used to limit the rotation of the limiting sleeve 14.

[0035] The limiting groove 13 can ensure the accuracy of reassembly and avoid installation errors caused by the rotation of the limiting sleeve 14.

[0036] The end cross-section of the limiting sleeve 14 is hexagonal, which can be clamped with tools such as wrenches, making it convenient to adjust the angle of the sweeping pipe 9 and avoiding damage to the sweeping pipe 9.

[0037] Working principle: After the filter press is completed, the drive mechanism 5 drives the walking mechanism 6 to pull open the filter press plate 2.

[0038] After the filter press plate 2 is pulled open, the filter cake at the bottom will fall directly. Then, compressed air is introduced into the sweeping pipe 9, and the air is discharged from the air outlet 11, forming an air blade. The air blade sweeps and blows the top of the filter press plate 2 to remove the residual filter cake at the top.

[0039] The angle of the sweeping pipe 9 can be adjusted according to the material and properties of the material.

[0040] Loosen the locking screw 10 to rotate the sweeping pipe 9. Determine the rotation angle based on the relative position of the indicator scale 16 and the indicator mark 17.

[0041] During maintenance, record the relative positions of scale 16 and indicator 17. After maintenance, during reassembly, reset the sweeping pipe 9 according to the record.
