Description

Technical Field

[0001] This utility model belongs to the field of grain and oil machinery technology, specifically relating to an oil residue separation device for edible oil processing. Background Technology

[0002] Edible oils are refined and processed vegetable or animal-derived fats used in cooking and food processing to provide energy and essential fatty acids, and are an indispensable component of our daily diet.

[0003] During the processing of edible oils, filtration is necessary to remove oil residue and ensure the quality of the final product. Currently, centrifugal filtration is commonly used to remove oil residue. However, with prolonged use, oil residue buildup can clog the filter media's pores, requiring regular replacement and cleaning, which affects the oil-residue separation efficiency. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides an oil residue separation device for edible oil processing that can continuously process oil residue separation and avoid blockage at the outlet during the frying separation process.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0006] An oil residue separation device for edible oil processing includes a frame, a rotating drum, a guide pipe, a spiral conveying blade, a feed pipe, a main motor, and an auxiliary motor. The rotating drum is rotatably supported by bearing seats inside the frame housing. An oil outlet guide hood and a residue outlet guide hood are respectively installed at both ends of the rotating drum. The guide pipe is coaxially and rotatably installed inside the rotating drum through bearings at both ends. The spiral conveying blade is installed on the guide pipe and is tangential to the inner wall of the rotating drum. The feed pipe is rotatably installed at the feed end of the guide pipe. The main motor is connected to the power input end of the guide pipe through a main differential, and the auxiliary motor is connected to the power input end of the rotating drum through an auxiliary differential.

[0007] Furthermore, the drum is divided into a separation zone and a drying zone, with the separation zone being cylindrical and the drying zone being conical.

[0008] Furthermore, the outlet of the guide pipe is located at the junction of the separation zone and the drying zone of the drum. The guide pipe part in the separation zone is cylindrical, and the guide pipe part in the drying zone is closed conical. The drum has an oil outlet and a slag outlet at both ends, which are rotatably connected to the oil outlet guide hood and the slag outlet guide hood, respectively.

[0009] Furthermore, the spiral conveying blade is a variable pitch spiral, with the pitch of the spiral conveying blade gradually decreasing from the separation zone to the drying zone, and a guide hole is provided on the spiral blade near the central guide tube.

[0010] Furthermore, the discharge port of the slag discharge guide hood is equipped with a squeezing roller, which is a dual-shaft configuration with roller teeth. The power input end of the squeezing roller is connected to the power output end of the secondary differential via a belt.

[0011] According to the above technical solution, the beneficial effects of this utility model are as follows: This utility model adopts a screw conveyor with a gradually decreasing pitch, which can better adapt to crude oil containing oil residue of different particle sizes. The gradually decreasing pitch along the direction of oil residue discharge can increase the pressure on the oil residue and further discharge the oil. The opening of the guide hole helps the oil attached to the oil residue to flow towards the liquid outlet, improving the separation efficiency. The extrusion roller set at the oil residue outlet can pull the oil residue at the outlet outward while crushing the oil residue, avoiding blockage of the outlet and affecting the separation efficiency of the oil residue.

Detailed Implementation

[0016] To more clearly illustrate the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0017] See Figure 1-3 An oil residue separation device for edible oil processing includes a frame 1, a drum 2, a guide pipe 3, a spiral conveying blade 4, a feed pipe 5, a main motor 6, and an auxiliary motor 7. The drum 2 is rotatably supported by bearing seats inside the housing 11 of the frame 1. An oil discharge guide hood 21 and a residue discharge guide hood 22 are respectively installed at both ends of the drum 2. The guide pipe 3 is coaxially rotatably installed inside the drum 2 through the bearings at both ends. The spiral conveying blade 4 is installed on the guide pipe 3 and is tangential to the inner wall of the drum 2. The feed pipe 5 is rotatably installed at the feed end of the guide pipe 3. The main motor 6 is connected to the power input end of the guide pipe 3 through a main differential 61, and the auxiliary motor 7 is connected to the power input end of the drum 2 through a secondary differential 71. When the guide pipe 3 and the drum 2 are rotating, there is a speed difference between their rotational speeds, and the speed difference pushes the oil residue particles toward the solid discharge port.

[0018] See Figure 1-3 The drum 2 is divided into a separation zone 23 and a drying zone 24. The separation zone 23 is cylindrical and the drying zone 24 is conical. When the crude oil that has been initially extracted enters the separation zone 23, the solid oil residue particles in the crude oil, regardless of their size, are adsorbed onto the inner wall of the drum 2 due to centrifugal force. They are then gradually pushed towards the drying zone 24 by the spiral conveying blades 4 that are close to the inner wall of the drum 2. The pressure of the gradually converging drum 2 on the oil residue gradually increases, squeezing out the oil attached to the oil residue.

[0019] See Figure 1-3 The outlet of the guide pipe 3 is located at the junction of the separation zone 23 and the drying zone 24 of the drum 2. The guide pipe 3 in the separation zone 23 is cylindrical, and the guide pipe 3 in the drying zone 24 is closed conical. The drum 2 has an oil outlet and a slag outlet at both ends, which are rotatably connected to the oil outlet guide hood 21 and the slag outlet guide hood 22, respectively. After the crude oil enters the drum 2 through the guide pipe 3, the oil slag is adsorbed on the inner wall of the drum 2 by centrifugal force and is pushed to the drying zone 24 by the spiral conveying blades. Then it is pushed to the solid outlet by the spiral conveying blades 4, while the oil flows to the oil outlet at the other end of the drum 2, thus realizing the separation of oil and slag.

[0020] See Figure 1-3 The spiral conveying blade 4 is a variable pitch spiral, and the pitch of the spiral conveying blade 4 gradually decreases from the separation zone 23 to the drying zone 24. A guide hole is opened on the spiral blade near the central guide pipe 3. The spiral conveying blade 4 with a gradually changing pitch can adapt to different types of crude edible oil. Regardless of the size of the oil residue particles in the crude oil, as the oil residue is pushed towards the solid discharge port, the gradually decreasing pitch and the converging drum 2 simultaneously provide gradually increasing pressure to the oil residue, further pressing out the oil attached to the oil residue, thereby improving the yield of edible oil processing and the separation efficiency of oil residue separation.

[0021] See Figure 1-3 The discharge port of the slag discharge guide hood 22 is equipped with a squeezing roller 25. The squeezing roller 25 is a dual-shaft configuration and has roller teeth. The power input end of the squeezing roller 25 is connected to the power output end of the secondary differential 71 via a belt. Since the oil slag contains cellulose, when the oil slag passes through the squeezing roller 25, the squeezing roller 25 will drive the oil slag at the discharge port to continuously detach, avoiding blockage of the discharge port. At the same time, the roller teeth on the squeezing roller 25 can break up the oil slag, making it easier for the oil slag to be processed and used in subsequent processes.

[0022] According to the above embodiments, the working process of this utility model is as follows:

[0023] The main motor 6 and auxiliary motor 7 are started, causing the drum 2 and guide pipe 3 to rotate in the same direction at different speeds. Crude oil is introduced into the feed pipe 5. After the crude oil enters the drum 2 through the guide pipe 3, the solid oil residue is adsorbed on the inner wall of the drum 2 due to the centrifugal sedimentation principle. Due to the speed difference between the spiral conveying blade 4 and the drum 2, the solid oil residue particles are pushed by the spiral conveying blade 4 to the drying zone 24 of the drum 2 and finally discharged from the solid discharge port. When passing through the extrusion roller 25, the oil residue blocks are broken up by the extrusion roller 25. The oil residue at the discharge port is continuously carried out by the internal cellulose, avoiding the oil residue from accumulating and clogging the discharge port. The oil flows from the guide hole on the spiral blade to the separation zone 23 and flows out from the liquid discharge port, realizing the separation of oil residue and residue.

Many modifications and variations can be made based on the content of this specification.
