Description

Technical Field

[0001] This utility model relates to the field of oil filtration technology, and in particular to a high-temperature circulating oil filtration tank. Background Technology

[0002] An oil filtration tank is a device used to purify liquid oil. It removes impurities through physical interception, adsorption, or magnetic separation and is widely used in the food processing industry. Its core structure includes the tank body, filtration mechanism, circulation pump, control system, and drain outlet. When working in conjunction with an fryer, the oil filtration tank is usually made of high-temperature resistant stainless steel. Depending on the application requirements, when the oil filtration tank is used as a stand-alone device, it has its own power and control system for centralized waste oil treatment or batch filtration, featuring high throughput and flexible mobility.

[0003] Oil filters are typically used in conjunction with fryers in the food processing industry, primarily to extend the shelf life of edible oil and ensure the quality of fried foods. They remove food residue from the fryer oil through a combination of physical filtration and chemical adsorption. In a typical application, during fryer oil use, a pump draws the oil into the oil filter, where the filtration system removes food residue. The cleaned oil is then returned to the fryer or stored for later use.

[0004] Currently, the filtration mechanism of the oil tank used in fryers on the market is usually a simple filter screen. However, because the mesh gaps of the filter screen are fixed, it can only filter a single type of food residue in the oil. This causes smaller particles to pass through the gaps between the filter screens and re-enter the fryer with the cleaned oil. As a result, some smaller food residues are still left inside the oil. When the fryer is used to fry food again, the food residues remaining in the oil adhere to the surface of the food, affecting the taste. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing technology makes it difficult to filter small food residues, which can affect the taste of food when the fryer continues to fry food. Therefore, a high-temperature circulating oil filtration tank is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-temperature circulating oil filtration tank includes a slag collection box installed inside the filtration tank. A conical pipe is installed on the slag collection box, with the small end of the conical pipe extending into the slag collection box. A spiral guide plate is fixedly connected to the inner wall of the conical pipe. A slag discharge groove communicating with the slag collection box is opened along the spiral direction of the guide plate. The tank also includes a conical filter cylinder fixedly installed inside the conical pipe. The large end of the conical filter cylinder has a closed structure and corresponds to the oil inlet end of the conical pipe. The conical filter cylinder has equidistantly arranged liquid inlet holes. The gap between the conical pipe and the conical filter cylinder forms a slag area. A filter element is set inside the slag collection box and is connected to the small end of the conical filter cylinder through a connecting filter pipe.

[0007] To filter out small food residues remaining in the oil, preferably, the filter element includes a filter box fixedly installed in a residue collection box, wherein an eccentric filter cylinder is rotatably installed inside the filter box, the cylindrical surface of the eccentric filter cylinder has an oil inlet hole, and a drive plate is fixedly installed on the cylindrical surface of the eccentric filter cylinder.

[0008] To prevent food residue from adhering to the surface of the eccentric filter cartridge, the angle between the axis of the eccentric filter cartridge and the axis of the connecting filter tube is further defined as 15-25 degrees.

[0009] To facilitate the discharge of purified oil, an oil drain pipe is fixedly installed on the filter box, with one end of the oil drain pipe extending into the filter box, and the eccentric filter cartridge is rotatably connected to the oil drain pipe.

[0010] To optimize oil flow, preferably, a ring of guide vanes is fixedly connected to the large end of the conical filter cartridge to guide the direction of oil flow.

[0011] To further filter small particulate residues, the inlet hole has a diameter range of 1mm-2mm, which is used to filter smaller food residues.

[0012] Compared with the prior art, this utility model provides a high-temperature circulating filter oil tank, which has the following beneficial effects: 1. This high-temperature circulating oil filtration tank, through the use of the conical pipe and conical filter cylinder provided in this application, allows the oil to enter the conical pipe and collide with the guide plate, thereby forming a spiral fluid and generating centrifugal force. This throws larger food residues in the oil into the slag discharge tank. At the same time, the oil enters the conical filter cylinder, which facilitates subsequent filter elements to process the slag again. This avoids the problem that the filter screen has fixed pore gaps and can only filter a single type of food residue in the oil.

[0013] 2. This high-temperature circulating oil filtration tank uses an eccentric filter cartridge with a drive plate. The connecting filter tube allows high-speed flowing oil to impact the drive plate tangentially along the eccentric filter cartridge. As the eccentric filter cartridge rotates, it interacts with the high-speed oil impacting the guide plate, creating a negative pressure on the side closest to the connecting filter tube. This pressure adsorbs the incoming oil, allowing it to enter and pass through the filter plate to filter out small food residues. Centrifugal force is generated on the side furthest from the connecting filter tube, ejecting the food residues. The purified oil then passes through the eccentric filter cartridge and is discharged through the drain pipe, completing the oil purification process. This prevents excessive impurities from clogging the filter elements, improving the filtration efficiency. By filtering out small particulate food residues, it avoids food residue residue remaining in the oil, which could affect the taste of the food.

[0014] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model utilizes a conical pipe and a conical filter cartridge in combination to accelerate the flow rate of the oil, enabling an oil circulation of 1200L / h. At the same time, in conjunction with the filter element, filtration is completed in stages, improving the purification effect and achieving a residue removal rate of ≥99.8%, thus avoiding the presence of too many small food residues in the oil.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: Reference Figures 1-4 A high-temperature circulating oil filtration tank includes a detachable slag collection box 7 installed inside the filtration tank. A conical pipe 1 is installed on the slag collection box 7, with the small end of the conical pipe 1 extending into the slag collection box 7. A spiral guide plate 4 is fixedly connected to the inner wall of the conical pipe 1. A slag discharge groove 3 connected to the slag collection box 7 is opened along the spiral direction of the guide plate 4. The tank also includes a conical filter cylinder 2 fixedly installed inside the conical pipe 1. The large end of the conical filter cylinder 2 has a closed structure and corresponds to the oil inlet end of the conical pipe 1. A ring-shaped guide plate is fixedly connected to the large end face of the conical filter cylinder 2 to guide the direction of oil flow. The conical filter cylinder 2 has equidistantly arranged liquid inlet holes 5 with a diameter range of 1mm-2mm, preferably 1.8mm, for filtering smaller food residues. A slag filter area is formed between the conical pipe 1 and the conical filter cylinder 2. A filter element is set inside the slag collection box 7 and is connected to the small end of the conical filter cylinder 2 through a connecting filter pipe 6.

[0020] Specifically, the conical pipe 1 and conical filter cartridge 2 provided in this application work together. When the oil enters the conical pipe 1 and collides with the guide plate 4, the guide plate 4 applies resistance to change the direction of oil flow, causing the oil to flow in a spiral shape. This throws larger food residues in the oil into the slag discharge tank 3. At the same time, after the oil enters the conical filter cartridge 2, the oil flow speed is further accelerated by the tapered structure of the conical filter cartridge 2, which facilitates the subsequent filter elements to process the residue again. This avoids the problem that the filter screen has fixed gaps and can only filter a single type of food residue in the oil.

[0021] The filter element includes a filter box 8 fixedly installed in a slag collection box 7. An eccentric filter cylinder 9 is rotatably installed inside the filter box 8. The angle between the axis of the eccentric filter cylinder 9 and the axis of the connecting filter pipe 6 is between 15 degrees and 25 degrees, preferably 20 degrees. An oil inlet hole 10 is opened on the cylindrical surface of the eccentric filter cylinder 9. A spiral drive plate 11 is fixedly installed on the cylindrical surface of the eccentric filter cylinder 9. The number of drive plates 11 is set to 6 to 10. In this application, the preferred number is 8. When the eccentric filter cylinder 9 rotates with the drive plate 11, the eccentric filter cylinder 9 generates centrifugal force to remove food residue. An oil drain pipe 12 is fixedly installed on the filter box 8. One end of the oil drain pipe 12 extends into the filter box 8. The eccentric filter cylinder 9 is rotatably connected to the oil drain pipe 12.

[0022] Specifically, the eccentric filter cartridge 9, which is set by the filter element, is used in conjunction with the drive plate 11. The filter tube 6 is connected so that the accelerated oil impacts the drive plate 11 along the tangential direction, which facilitates the rotation of the eccentric filter cartridge 9. When the eccentric filter cartridge 9 rotates, it creates a negative pressure on the side close to the filter tube 6, thereby adsorbing the incoming oil and allowing it to enter the interior. Fine food residues are filtered out. The side away from the filter tube 6 generates centrifugal force, which throws out the food residues. The purified oil passes through the eccentric filter cartridge 9 and is discharged through the oil drain pipe 12, thus completing the oil purification. This avoids excessive impurities clogging the filter element and improves the purification effect of the filtration mechanism. By filtering out small particulate food residues, it avoids food residues remaining in the oil, which could affect the taste of the food.

[0023] In this invention, the oil to be filtered enters the conical pipe 1 through the oil inlet pipe connected to the conical pipe 1. When the oil flows with the guide plate 4, the oil forms a vortex fluid due to the collision with the guide plate 4. After the oil generates centrifugal force, the large food particles are thrown towards the inner wall of the conical pipe 1 because of their higher density. After colliding with the inner wall of the conical pipe 1, they fall into the slag discharge trough 3. Subsequently, with the continuous entry of subsequent oil, the food particles in the slag discharge trough 3 move along the slag discharge trough 3 and finally fall into the slag collection box 7. Then, the oil impacts the large end of the conical filter cylinder 2. Through the conical protrusion set at the large end of the conical filter cylinder 2, the oil enters the slag area between the conical pipe 1 and the conical filter cylinder 2. Before the oil enters the conical filter cylinder 2, smaller food particles are filtered through the liquid inlet 5. The oil pushes the smaller food particles to merge with the large particles in the slag discharge trough 3 and discharge them into the slag collection box 7. The oil then enters the conical filter cartridge 2, and the tapered structure of the conical filter cartridge 2 accelerates the speed at which the oil is sprayed out of the connecting filter tube 6, causing the oil to enter the filter box 8. Some of the oil falls into the residue collection box 7 along with the food residue. Due to the negative pressure created by the oil flow in the connecting filter tube 6, the oil also enters the connecting filter tube 6 and then the filter box 8. The connecting filter tube 6 can block the separated food residue. When the accelerated oil enters the filter box 8, it first impacts the drive plate 11 set in the eccentric filter cartridge 9. The eccentric filter cartridge 9 is impacted by the drive plate 11. After being struck, the filter cartridge 9 rotates along the axis of the filter box 8. When the eccentric filter cartridge 9 rotates to a position close to the connecting filter cartridge, a negative pressure is generated on the surface of the eccentric filter cartridge 9 due to the high-speed oil flow, which adsorbs tiny food residues. Then, when the eccentric filter cartridge 9 rotates away from the connecting filter tube 6, centrifugal force is generated due to its own rotation, which throws the tiny food residues off the surface and makes them fall into the filter box 8, thereby preventing food residues from clogging the surface of the eccentric filter cartridge 9. The oil enters the eccentric filter cartridge 9 through the oil inlet hole 10 to complete the filtration and purification, and then is discharged through the oil drain pipe 12.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
