Technical Field
[0001] This utility model relates to the field of walnut oil filtration technology, specifically a filtration device for removing flocculent matter from walnut oil. Background Technology
[0002] Walnut oil is a vegetable oil made from walnut kernels through pressing. It is an edible oil. After pressing walnut kernels into walnut oil, a lot of flocculent matter remains in the oil. Therefore, it is necessary to filter out the flocculent matter in the walnut oil, which requires the use of filtration equipment.
[0003] However, due to the high viscosity of walnut oil, its weight slows its passage through the filter screen during filtration, resulting in a slow filtration rate. Furthermore, the rate at which walnut oil containing flocculent matter enters the filtration equipment is also affected by its viscosity. Therefore, we propose a filtration device for removing flocculent matter from walnut oil. Utility Model Content
[0004] The purpose of this invention is to provide a filtration device for removing flocculent matter from walnut oil. By setting a piston structure inside the filter cylinder, the movement of the piston creates negative pressure during walnut oil filtration, allowing the walnut oil to be drawn in quickly and smoothly. Then, the movement of the piston pressurizes the walnut oil downwards, enabling it to quickly pass through the filter basket and have the flocculent matter removed, thereby improving filtration efficiency and solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for removing flocculent matter from walnut oil, comprising a filter cylinder and a lower cylinder. The lower cylinder is detachably installed below the filter cylinder, and a filter basket is placed inside the lower cylinder, with an open structure at the top. An electric push rod is vertically installed on the surface of the filter cylinder, with its extended end penetrating into the interior of the filter cylinder. A piston is fixed to the end of the electric push rod, and the piston slidably contacts the inner wall surface of the filter cylinder. A feed hopper is provided on the side of the filter cylinder, and the bottom of the feed hopper is connected to the lower side of the filter cylinder via a feed pipe. A ball chamber connected to the feed pipe is provided on the feed pipe, and a ball is placed in the ball chamber. The bottom of the lower cylinder is connected to a discharge pipe connected to its interior, and a downward-directing one-way valve is installed on the discharge pipe.
[0006] By adopting the above technical solution, when the piston is driven to move upward, it uses negative pressure to draw in walnut oil from the feed hopper. When the piston moves downward, it pressurizes the walnut oil, causing it to pass through the filter basket and be filtered. Finally, flocculent matter is left and the filtered walnut oil is discharged.
[0007] Optionally, the upper inner ring of the lower cylinder and the lower outer ring of the filter cylinder are both provided with threads, and the lower cylinder is screwed onto the lower part of the filter cylinder to achieve detachable installation.
[0008] By adopting the above technical solution, the lower cylinder can be removed more easily, so that the filter basket can be cleaned or replaced.
[0009] Optionally, multiple baffles are fixed in the longitudinal direction at the lower part of the ball chamber, and the distance between the baffles is smaller than the diameter of the ball to support the ball.
[0010] By adopting the above technical solution, the piston can be prevented from moving upward and sucking in walnut oil, while the ball can move downward and block the feed pipe below.
[0011] Optionally, an annular plate is fixed around the upper outer ring of the filter basket, and the annular plate is locked between the filter cylinder and the lower cylinder connection.
[0012] By adopting the above technical solution, the ring plate is clamped and locked between the filter cylinder and the lower cylinder, which can achieve stable locking of the filter basket.
[0013] Optionally, the inner diameters of the feed pipes on both sides of the ball chamber are the same, and the diameter of the ball block is larger than the inner diameter of the feed pipe.
[0014] By adopting the above technical solution, when the piston moves downward and the ball is pushed upward, it can block the upper feed pipe and seal it.
[0015] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0016] 1. The technical solution of this application sets a piston structure inside the filter cartridge. When filtering walnut oil, the movement of the piston creates negative pressure, which allows the walnut oil to be drawn in quickly and smoothly. Then, the movement of the piston pressurizes the walnut oil downward, allowing it to pass through the filter basket quickly and be filtered to remove flocculent matter, thereby improving the filtration efficiency.
[0017] 2. The technical solution of this application connects the lower cylinder to the bottom of the filter cartridge by screwing it on. The structure is relatively simple to disassemble and assemble, and the lower cylinder can be removed more easily for cleaning or replacement of the filter basket. Attached Figure Description

[0023] Please see Figure 1-3 This utility model provides a technical solution: a filtration device for removing flocculent matter from walnut oil, including a filter cylinder 1 and a lower cylinder 2. The lower cylinder 2 is detachably installed below the filter cylinder 1. This detachable structure can be achieved by having threads arranged around both the upper inner ring of the lower cylinder 2 and the lower outer ring of the filter cylinder 1, so that the lower cylinder 2 can be detachably installed by screwing it onto the lower part of the filter cylinder 1. Alternatively, other detachable structures, such as flanges, can be used to achieve detachable installation of the lower cylinder 2. A filter basket 5 is placed inside the lower cylinder 2. The filter basket 5 has an open structure at the top. When connected by a threaded connection, a ring plate 51 is fixed around the upper outer ring of the filter basket 5. The ring plate 51 is locked between the connection between the filter cylinder 1 and the lower cylinder 2, so that the filter basket 5 is stably locked inside the lower cylinder 2 and will not move up and down. When the lower cylinder 2 is unscrewed and removed, the filter basket 5 can be easily taken out for cleaning or replacement.
[0024] A feed hopper 3 is provided on the side of the filter cylinder 1. The bottom of the feed hopper 3 is connected to the lower side of the filter cylinder 1 through a feed pipe 31. The bottom of the lower cylinder 2 is connected to a discharge pipe 21 that is connected to its interior. The walnut oil to be filtered is added from the feed hopper 3 and then enters the filter cylinder 1 through the feed pipe 31. Finally, after being filtered by the filter basket 5, it is discharged from the discharge pipe 21 at the bottom.
[0025] To improve the throughput and filtration speed of walnut oil, an electric push rod 4 is vertically installed on the surface of the filter cylinder 1. The protruding end of the electric push rod 4 extends into the interior of the filter cylinder 1, and a piston 41 is fixed to the end of the electric push rod 4. The piston 41 slidably contacts the inner wall surface of the filter cylinder 1. Simultaneously, a ball chamber 32 communicating with the feed pipe 31 is provided on the feed pipe 31, and a blocking ball 321 is placed in the ball chamber 32. Multiple baffles are fixed longitudinally in the lower part of the interior of the ball chamber 32. The spacing between the baffles 322 is smaller than the diameter of the blocking ball 321, thus supporting the blocking ball 321. The inner diameters of the feed pipes 31 on both sides of the ball chamber 32 are the same, while the diameter of the blocking ball 321 is larger than the inner diameter of the feed pipe 31. The discharge pipe 2... A downward-directing one-way valve 211 is installed on the filter cartridge 1. Therefore, when the piston 41 is driven upward by the electric push rod 4, the one-way valve 211 is blocked, and the ball stopper 321 is blocked by the stop rod 322 and will not block the feed pipe 31 below. This allows the walnut oil in the feed hopper 3 to be quickly drawn into the filter cartridge 1 by negative pressure through the feed pipe 31. Then, the piston 41 is driven downward by the electric push rod 4. The pressurized walnut oil will push the ball stopper 321 upward, causing the ball stopper 321 to contact the feed pipe 31 above the ball chamber 32 and block it. This allows pressure to be applied so that the walnut oil moves downward and is filtered through the filter basket 5 under pressure. After that, it is discharged from the discharge pipe 21 through the one-way valve 211.
[0026] In use, connect the electric actuator 4 to the industrial control equipment and control the electric actuator 4 to drive the piston 41 to move up and down reciprocally. When the electric actuator 4 moves to the lowest point, ensure that the bottom height of the piston 41 is greater than the height of the bottom of the feed pipe 31 connected to the surface of the filter cartridge 1, so that the walnut oil to be filtered is added from the feed hopper 3. When the piston 41 is driven upward by the electric actuator 4, due to the gravity of the blocking ball 321 and the gravity of the walnut oil, it is positioned at the bottom next to the stop lever 322, and will not block the feed pipe 31. However, the discharge pipe 21 is only open downward in one direction under the action of the one-way valve 211, which will create a negative pressure in the filter cartridge 1. The walnut oil is then drawn from the feed hopper 3 into the filter cylinder 1 through the feed pipe 31. When the electric push rod 4 drives the piston 41 to move downward, the pressurized walnut oil will push upward against the blocking ball 321, causing the blocking ball 321 to contact the feed pipe 31 in the upper part of the ball chamber 32 and block it. This applies pressure to make the walnut oil move downward and be filtered through the filter basket 5 under pressure. After that, it is discharged from the discharge pipe 21 through the one-way valve 211. The above operation can be repeated to filter the walnut oil. After the filtration is completed, the lower cylinder 2 can be rotated to unscrew it and the filter basket 5 can be taken out for cleaning or replacement.
