Description

Technical Field

[0001] This utility model relates to the field of starch processing technology, specifically to a multi-stage cyclone separator for starch processing. Background Technology

[0002] A multistage hydrocyclone separator is a separation device designed with multiple cascaded hydrocyclones, primarily used for handling complex separation tasks. It utilizes multiple single-stage hydrocyclones connected in series to process finer particulate materials, providing higher separation accuracy and processing speed. Liquids or gases are introduced into the hydrocyclones and subjected to rotational motion, causing the fluid to flow along a spiral path. During this process, solid particles or droplets in the fluid are separated due to centrifugal force, settling to the bottom of the hydrocyclone or being discharged.

[0003] The prior art disclosure number CN211611937U discloses a multi-stage hydrocyclone for starch production, including a cylindrical body with an overflow pipe connected to the top. The bottom of a torsion spring is engaged with the outer wall of a first through-hole block. The tops of two clamping rods are engaged with the inner wall of a recessed block. A T-shaped rod penetrates the top of each of the two recessed blocks, with its outer wall extending through the top of the clamping rod. A first compression spring is fitted with the outer wall of the T-shaped rod, its top engaged with the outer wall of the T-shaped rod, and its bottom engaged with the top of the recessed block. This multi-stage hydrocyclone for starch production, through the cooperation between the first filter plate, clamping rods, and recessed blocks, allows the first filter screen to filter fine particles about to enter the overflow pipe. This avoids the problems of existing hydrocyclones that require flanges, bolts, and nuts for installation, and whose disassembly, maintenance, and cleaning of the hydrocyclone are time-consuming and labor-intensive, affecting work efficiency.

[0004] With the above configuration, the hydrocyclone described in the prior art, through the cooperation between the first filter plate, the clamping rod, and the grooved block, allows the first filter screen to filter fine particles about to enter the overflow pipe; the cooperation between the second filter plate, the arc-shaped rack, and the gear allows the second filter plate to filter coarse particles about to flow out of the conical cylinder; and the cooperation between the crank rod, the screw, and the groove allows for quick disassembly of the multi-stage hydrocyclone used for starch production. However, the hydrocyclone of the prior art has the following drawbacks during operation:

[0005] The existing device requires multiple handles to be turned to disassemble the first filter screen when it needs to be removed. This causes the barrel to detach from the conical barrel. Moreover, the device vibrates during use, which can cause the handles to rotate and the barrel to detach from the conical barrel. Then, it is necessary to reach into the barrel and pull the T-shaped rod upwards to remove the first filter screen. Since the inside of the barrel is small, it is very inconvenient to pull the T-shaped rod, and two T-shaped rods need to be pulled at the same time, making the disassembly process very troublesome. Utility Model Content

[0006] This utility model aims to provide a multi-stage cyclone separator for starch processing, mainly to solve the technical problems of existing devices that vibrate during use, causing the handle to rotate, and making it very inconvenient to disassemble the first filter screen.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A multi-stage hydrocyclone separator for starch processing includes a barrel, a conical barrel, and an overflow pipe. A first fixing ring is fixed to the outer wall of the barrel, and a second fixing ring is fixed to the outer wall of the conical barrel. Symmetrical sliding cylinders are fixed to the upper surface of the second fixing rings. Limiting components are provided on the inner wall of the sliding cylinders. The overflow pipe is installed inside the barrel and has an L-shaped rod fixed to its outer wall. A filter screen is installed on the bottom surface of the overflow pipe. Symmetrical inserts are fixed to the outer wall of the filter screen. The inserts are inserted into the inner wall of the L-shaped rod. A movable groove is formed on the inner wall of the L-shaped rod. A limiting rod is slidably connected to the inner wall of the movable groove. A limiting spring is fixed to the inner wall of the movable groove. The other end of the limiting spring is fixed to the limiting rod. A limiting groove is formed on the outer wall of the insert. The limiting rod is inserted into the limiting groove. A sliding groove is formed on the bottom surface of the insert. A quick-release component is provided on the inner wall of the sliding groove.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working principle: When this device is needed, first connect the overflow pipe to the external pipeline. After connection, the starch liquid mixed with coarse and fine particles flows into the tank through the external starch liquid conveying device. Then, the coarse and fine particles of the starch liquid are separated. When the filter screen needs to be replaced, first adjust the limiting component so that the U-shaped rod moves upward under the action of the threaded rod, so that the U-shaped rod disengages from the fixing groove. Then the tank can be removed. Then adjust the quick release component so that the limiting rod disengages from the limiting groove. Then, pull the filter screen to remove it.

[0011] 2. Beneficial effects:

[0012] Existing technology utilizes the cooperation between the first filter plate, the clamping rod, and the grooved block to filter fine particles entering the overflow pipe; the cooperation between the second filter plate, the arc-shaped rack, and the gear to filter coarse particles exiting the conical cylinder; and the cooperation between the crank rod, the screw, and the groove to allow for quick disassembly of the multi-stage hydrocyclone used in starch production. However, existing devices require multiple handles to be turned to detach the barrel from the conical cylinder when disassembling the internal first filter plate. Furthermore, the device vibrates during operation, which can cause the handles to rotate, leading to the barrel detaching from the conical cylinder, requiring manual intervention inside the barrel. The first filter screen can only be removed by pulling the T-shaped rod upwards. Due to the small size of the barrel, pulling the T-shaped rod is very inconvenient, and both T-shaped rods need to be pulled simultaneously, making the disassembly process very cumbersome. This solution uses a limiting component, an L-shaped rod, a plug, a U-shaped rod, and a quick-release component. The plug and L-shaped rod are inserted to allow the limiting rod to be inserted into the limiting groove. By adjusting the quick-release component, the L-shaped rod and plug can be quickly disassembled and installed. The limiting component then fixes the barrel and the conical barrel to prevent them from detaching. Pressing the quick-release component makes disassembly even more convenient. At the same time, the internal toothed ring prevents the threaded rod from rotating, thus preventing the barrel from detaching from the conical barrel.

[0013] Preferably, the limiting component includes a U-shaped rod that is slidably connected to the inner wall of the slide cylinder. One end of the U-shaped rod has a vertical groove, and a threaded rod is threaded onto the inner wall of the groove. A rotating rod is fixedly connected to one end of the threaded rod passing through the U-shaped rod, and a gear is fixedly connected to the end of the rotating rod away from the threaded rod. An internal gear ring is rotatably connected to the lower surface of the second fixing ring, and the internal gear ring meshes with the gear. Symmetrical fixing grooves are formed on the upper surface of the first fixing ring, and the end of the U-shaped rod away from the threaded rod is inserted into one of the fixing grooves. By setting the limiting component, the barrel body and the conical barrel can be fixed. Simultaneously, the internal gear ring facilitates gear rotation and disassembly.

[0014] Preferably, the quick-release assembly includes a slider that is slidably connected to the inner wall of the groove. A push rod is fixedly connected to the lower surface of the slider, and a compression spring is sleeved on the outer wall of the push rod. One end of the compression spring is fixedly connected to the slider, and the other end of the compression spring is fixedly connected to the groove. The push rod passes through the insert block and is slidably connected to it. The outer wall of the limiting rod has an inclined surface, and the slider abuts against the inclined surface. By setting the quick-release assembly, the slider can be pushed into the movable groove by pressing the push rod, allowing the filter screen to be replaced.

[0015] Preferably, the lower surface of the second fixing ring has a rotating groove, the inner wall of which is fixedly connected to a tension spring. The other end of the tension spring is fixedly connected to a pull rod, which is slidably connected to the rotating groove. The other end of the pull rod is rotatably connected to a rotating shaft, one end of which is fixedly connected to a crossbar. A square block is fixedly connected to the upper surface of the crossbar, and the bottom surface of the gear has a square groove into which the square block is inserted. By using the tension spring and the square block, the gear can be fixed by the elastic force of the tension spring and the square block, preventing rotation of the gear.

[0016] Preferably, the lower surface of the insert block has a slot, and a knob is fixedly connected to the end of the push rod away from the slider. A locking block is fixedly connected to the outer wall of the knob, and the locking block engages with the slot. By setting the locking block and the slot, when the push rod is pressed and rotated, the locking block is engaged into the slot, limiting the push rod and facilitating the removal of the filter screen.

[0017] Preferably, the groove and the slider are matched, and both the groove and the slider are T-shaped. This prevents the slider from disengaging, making the push rod more stable.

[0018] Preferably, both ends of the threaded rod are fixed with abutment plates. This prevents the threaded rod from detaching from the second retaining ring, making it easier to fix the U-shaped rod. Attached Figure Description
