Description

Technical Field

[0001] This utility model relates to the field of starch processing technology, and in particular to a starch cyclone washing device. Background Technology

[0002] A hydrocyclone consists of a hydrocyclone cylinder, a feeding device, a separation device, an underflow device, an overflow device, hydrocyclone tubes (ranging from a dozen to hundreds), and O-ring seals A. The cylinder is divided into three chambers—overflow, feeding, and underflow—by a baffle plate, all sealed with O-ring seals A. The hydrocyclone tubes connect to each of the three chambers. This equipment is mainly used to remove fine fibers, proteins, and cell sap from starch slurry for concentration, recovery, refining, and washing of the starch slurry.

[0003] Existing hydrocyclones are assembled from multiple components such as a cylinder, baffles, hydrocyclones, and sealing caps. When the inside of the hydrocyclone is blocked and needs to be disassembled for internal cleaning, it is inconvenient to remove and install the baffles, hydrocyclones, etc., which are located inside the cylinder. Therefore, a starch hydrocyclone washing device that facilitates the installation and removal of internal components of the cylinder is needed. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a starch cyclone washing device. By pulling the sealing cover, the sealing cover causes the telescopic tubes A and B to extend and retract. The extension and retraction of telescopic tube A causes the overflow baffle, the underflow baffle, and the cyclone tube to enter and exit the cylinder. The extension and retraction of telescopic tube B facilitates the loading and unloading of the cyclone tube between the overflow baffle and the underflow baffle, thereby facilitating the loading and unloading of internal components of the cylinder.

[0005] This utility model is achieved through the following technical solution: a starch cyclone washing device is provided, including a cylinder body. The cylinder body is divided into an overflow chamber, a feed chamber, and an underflow chamber by an overflow baffle, an underflow baffle, and a sealing cover. A plurality of cyclone tubes connecting the overflow chamber, the feed chamber, and the underflow chamber are provided between the overflow baffle and the underflow baffle. The overflow baffle is connected to the cylinder body by a telescopic tube A extending axially along the cylinder body. The underflow baffle is connected to the overflow baffle by a telescopic tube B extending axially along the cylinder body. The underflow baffle is fixedly connected to the sealing cover, and the sealing cover is connected to the cylinder body by a fastening device. Pulling the sealing cover causes the telescopic tubes A and B to extend and retract. The extension and retraction of the telescopic tube A causes the overflow baffle, the underflow baffle, and the cyclone tubes to enter and exit the cylinder body. The extension and retraction of the telescopic tube B loads and unloads the cyclone tubes between the overflow baffle and the underflow baffle, facilitating the loading and unloading of the internal components of the cylinder body.

[0006] As an optimization, a return spring A is provided inside telescopic tube A, extending along the axial direction of telescopic tube A, and a return spring B is provided inside telescopic tube B, extending along the axial direction of telescopic tube B; when the fastening device is opened, the return spring A extends and causes the telescopic tube A to extend, and the overflow baffle, underflow baffle and swirl tube automatically pop out of the cylinder; the return spring B extends and causes the telescopic tube B to extend, and the swirl tube automatically detaches from the underflow baffle.

[0007] As an optimization, the spring constant of return spring A is greater than that of return spring B; by having return spring B contract before return spring A and relax after return spring A, the swirl tube can be installed and removed outside the cylinder, thus avoiding the swirl tube from falling off inside the cylinder or being difficult to install accurately on the underflow baffle.

[0008] As an optimization, the telescopic pipe A includes several sleeves that are sequentially nested together, and adjacent sleeves are connected by a sealing ring A; the sealing ring A prevents fluid from entering the sleeves.

[0009] As an optimization, the sleeve is equipped with matching slots and springs, and adjacent sleeves are connected by the slots and springs; the slots and springs prevent the sleeves from separating from each other, thereby preventing the overflow baffle, underflow baffle and vortex tube from falling off during the writing process.

[0010] As an optimization, the outer diameter of the overflow baffle is smaller than that of the underflow baffle. The cylinder body is provided with support platform A and support platform B extending along the circumference of the cylinder body. Support platform A is adapted to the overflow baffle, and support platform B is adapted to the underflow baffle. The stability of the overflow baffle and the underflow baffle is increased by support platform A and support platform B respectively.

[0011] The beneficial effects of this utility model are as follows: when the sealing cover is pulled, the sealing cover causes the telescopic tube A and the telescopic tube B to extend and retract. The extension and retraction of the telescopic tube A causes the overflow baffle, the underflow baffle and the swirl tube to enter and exit the cylinder body. The extension and retraction of the telescopic tube B causes the swirl tube to be installed and unloaded between the overflow baffle and the underflow baffle, which facilitates the installation and removal of internal components of the cylinder body.

[0012] When the fastening device is opened, the return spring A extends and causes the telescopic tube A to extend, and the overflow baffle, underflow baffle and swirling tube automatically pop out of the cylinder; the return spring B extends and causes the telescopic tube B to extend, and the swirling tube automatically detaches from the underflow baffle.

[0013] By having the return spring B contract before the return spring A and then relax after the return spring A, the swirl tube can be installed and removed outside the cylinder, thus preventing the swirl tube from falling off inside the cylinder or being difficult to install accurately on the underflow baffle.

Detailed Implementation

[0015] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0016] like Figure 1 and Figure 3 The starch cyclone washing device of this utility model includes a cylinder 1. The cylinder 1 is divided into an overflow chamber 101, a feeding chamber 102, and a bottom flow chamber 103 by an overflow baffle 2, a bottom flow baffle 3, and a sealing cover 4. A plurality of cyclone tubes 5 are provided between the overflow baffle 2 and the bottom flow baffle 3 to connect the overflow chamber 101, the feeding chamber 102, and the bottom flow chamber 103. The overflow baffle 2 is connected to the cylinder 1 by a telescopic tube A6 extending along the axial direction of the cylinder 1. The bottom flow baffle 3 is connected to the overflow baffle 2 by a telescopic tube B7 extending along the axial direction of the cylinder 1. The bottom flow baffle 3 and the sealing cover 4 are fixedly connected. The sealing cover 4 is connected to the cylinder 1 by a fastening device 8.

The fastening mechanism is existing technology and can adopt threaded hole structure, etc. The way telescopic tube B7 connects overflow baffle 2 and underflow baffle 3 is similar to that of telescopic tube A6; fastening device 8 is existing technology and can adopt bolt and nut connection.

[0018] Open the fastening device 8, pull the sealing cover 4, the sealing cover 4 drives the telescopic tube B7 to extend through the underflow baffle 3, the telescopic tube B7 drives the telescopic tube A6 to extend through the overflow baffle 2; the telescopic tube A6 extends, the overflow baffle 2, the underflow baffle 3 and the swirling tube 5 extend out of the cylinder 1; the telescopic tube B7 extends, the distance between the overflow baffle 2 and the underflow baffle 3 increases, and the swirling tube 5 disengages from the underflow baffle 3.

[0019] Pushing the sealing cover 4 causes the sealing cover 4 to retract the telescopic tube B7 via the underflow baffle 3. The telescopic tube B7 then retracts the telescopic tube A6 via the overflow baffle 2. As the telescopic tube A6 retracts, the overflow baffle 2, the underflow baffle 3, and the swirling tube 5 enter the cylinder body 1. As the telescopic tube B7 retracts, the swirling tube 5 is snapped between the overflow baffle 2 and the underflow baffle 3, and the cylinder body 1 and the sealing cover 4 are fixed together by the fastening device 8.

[0020] like Figure 1and Figure 3 The telescopic tube A6 shown is provided with a return spring A9 extending along the axial direction of the telescopic tube A6, and the telescopic tube B7 is provided with a return spring B10 extending along the axial direction of the telescopic tube B7.

[0021] When the fastening device 8 is opened, the return spring A9 extends and causes the telescopic tube A6 to extend, the sealing cover 4 opens automatically, and the overflow baffle 2, the underflow baffle 3 and the swirl tube 5 automatically pop out of the cylinder 1; the return spring B10 extends and causes the telescopic tube B7 to extend, and the swirl tube 5 automatically detaches from the underflow baffle 3.

[0022] Pushing the sealing cover 4 causes the sealing cover 4 to retract the telescopic tube B7 via the underflow baffle 3, and the return spring B10 retracts. The telescopic tube B7 then retracts the telescopic tube A6 via the overflow baffle 2, and the return spring A9 retracts. When the telescopic tube A6 retracts, the overflow baffle 2, the underflow baffle 3, and the swirling tube 5 enter the cylinder body 1. When the telescopic tube B7 retracts, the swirling tube 5 is engaged between the overflow baffle 2 and the underflow baffle 3, and the cylinder body 1 and the sealing cover 4 are fixed together by the fastening device 8.

[0023] like Figure 1 and Figure 3 The spring constant of the reset spring A9 shown is greater than that of the reset spring B10.

[0024] When the fastening device 8 is opened, the return spring A9 extends and drives the telescopic tube A6 to gradually extend, the sealing cover 4 opens automatically, and the overflow baffle 2, the underflow baffle 3 and the swirling tube 5 automatically pop out of the cylinder 1; after the overflow baffle 2, the underflow baffle 3 and the swirling tube 5 pop out of the cylinder 1, the return spring B10 extends and drives the telescopic tube B7 to gradually extend, and the swirling tube 5 automatically detaches from the underflow baffle 3.

[0027] As the telescopic tube A6 gradually extends and retracts, the sleeve 601 slides relative to it, causing the sealing ring A603 to move.

[0028] like Figure 2 The sleeve 601 shown is provided with a matching slot and a spring piece 602, and adjacent sleeves 601 are connected by the slot and the spring piece 602.

[0029] The telescopic tube A6 gradually extends and retracts, and the sleeve 601 slides relative to each other until the spring piece 602 on the sleeve 601 is engaged in the slot of the adjacent sleeve 601.

[0030] like Figure 1 and Figure 3 The outer diameter of the overflow baffle 2 shown is smaller than the outer diameter of the underflow baffle 3. The cylinder body 1 is provided with a support platform A11 and a support platform B12 extending circumferentially along the cylinder body 1. The support platform A11 is adapted to the overflow baffle 2, and the support platform B12 is adapted to the underflow baffle 3.

[0031] The sealing cover 4 drives the underflow baffle 3 to move toward the cylinder body 1 until the underflow baffle 3 and the support platform B12 come into contact; the underflow baffle 3 drives the overflow baffle 2 to move toward the cylinder body 1 through the telescopic tube B7 until the overflow baffle 2 and the support platform A11 come into contact.

[0032] In actual use, when the fastening device 8 is opened, the return spring A9 extends and drives the telescopic tube A6 to gradually extend, the sealing cover 4 opens automatically, and the overflow baffle 2, the underflow baffle 3 and the swirling tube 5 automatically pop out of the cylinder 1.
