Description

Technical Field

[0001] This utility model relates to the field of dye liquor filtration, and in particular to a dye liquor circulation filtration device. Background Technology

[0002] In continuous production lines, dye liquor in printing and dyeing enterprises accumulates solid impurities, lint, sizing agents, and other substances during repeated use. The presence of these substances significantly impacts the dyeing process. Therefore, it is necessary to filter the dye liquor during production for reuse.

[0003] Because the dye liquor in the dyeing and printing equipment comes into direct contact with the fabric, it carries a large amount of solid impurities such as lint. In order to ensure the effectiveness of its recycling, the dye liquor needs to be filtered. However, the solid impurities it carries can cause the filter structure to become clogged frequently, so the staff needs to replace or clean the filter structure in a timely manner, which is quite inconvenient.

[0004] Therefore, it is necessary to provide a dye liquor circulation filtration device to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a dye liquor circulation filtration device, which solves the problem that solid impurities carried in the dye liquor cause the filtration structure to be frequently blocked, so that staff need to replace or clean the filtration structure in a timely manner, which is quite inconvenient.

[0006] To solve the above-mentioned technical problems, this utility model provides a dye liquor circulation filtration device, including a filter box with a conical upper part, and a filter screen plate is horizontally fixedly connected inside the filter box. The filter screen plate divides the inner cavity of the filter box into a lower cavity and an upper cavity.

[0007] The lower outer surface of the filter box is fixedly connected to an inlet pipe communicating with the interior of the lower cavity. The top of the filter box is fixedly connected to a drain pipe communicating with the interior of the upper cavity. One side surface of the filter box is fixedly connected to a siphon pipe communicating with the interior of the lower cavity. The other end of the siphon pipe is bent upward and extends to the top of the drain pipe, then bent downward and extends downward to the bottom of the filter box.

[0008] Preferably, the bottom of the filter box is vertically fixedly connected with multiple support legs, and a reinforcing rod is fixedly connected between every two adjacent support legs.

[0009] Preferably, the outer surface of the upwardly extending portion of the siphon tube is connected to a rupture tube, and the other end of the rupture tube penetrates the upper surface of the filter box and extends to the bottom of the upper cavity.

[0010] Preferably, a reflux pool is provided at the bottom end of the siphon pipe.

[0011] Preferably, a circulation tank is provided at the bottom end of the drain pipe.

[0012] Preferably, the inlet pipe is equipped with a solenoid valve, and the downward bend of the siphon pipe is equipped with a sensor.

[0013] Preferably, a spherical filter screen is fixedly connected to the bottom end of the destruction tube and inside the upper cavity.

[0014] Compared with related technologies, the dye liquor circulation filtration device provided by this utility model has the following beneficial effects: This utility model provides a dye liquor circulation filtration device, which, by setting up a filter box and a siphon pipe, allows the dye liquor to be transported from the inlet pipe into the lower chamber inside the filter box during use. Once the lower chamber is full, the dye liquor level rises and passes through the filter screen into the upper chamber. During this process, impurities in the dye liquor are filtered by the filter screen. When the upper chamber is also full, the filtered dye liquor is discharged through the drain pipe into the circulation system. As the filter screen continues to filter, the impurities attached to it will change... The more dye flows through, the slower the filtration process becomes, resulting in poorer dye flow. The level of dye in the siphon tube continuously rises. When the level reaches its maximum, the dye flows downwards from the bend, creating a siphon effect. This causes the dye in the filter box to flow back, while the dye in the upper chamber flows downwards and is drawn into the siphon tube. This process effectively cleans the filter screen in reverse. After the siphon process ends, the device returns to its original state and continues filtration, thus achieving automatic cleaning of blockages without manual intervention, improving convenience.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1-3 The dye liquor circulation filtration device includes a filter box 1 with a cone shape at the top. A filter screen plate 2 is horizontally fixed inside the filter box 1. The filter screen plate 2 divides the inner cavity of the filter box 1 into a lower cavity 3 and an upper cavity 4.

[0023] The lower outer surface of the filter box 1 is fixedly connected to an inlet pipe 5 that communicates with the interior of the lower chamber 3. The top of the filter box 1 is fixedly connected to a drain pipe 6 that communicates with the interior of the upper chamber 4. One side surface of the filter box 1 is fixedly connected to a siphon pipe 7 that communicates with the interior of the lower chamber 3. The other end of the siphon pipe 7 is bent upward and extends to the top of the drain pipe 6, then bent downward and extends downward to the bottom of the filter box 1.

[0024] In operation, the dye liquor is fed into the lower chamber 3 of the filter box 1 through the inlet pipe 5. Once the lower chamber 3 is full, the dye liquor level rises and passes through the filter screen 2 into the upper chamber 4. During this process, impurities in the dye liquor are filtered by the filter screen 2. When the upper chamber 4 is also full, the filtered dye liquor is discharged through the drain pipe 6 into the circulation system, thus achieving a filtration effect. However, as the filter screen 2 continues to filter, the amount of impurities adhering to it increases, causing its filtration effect to slow down and the passage of dye liquor to deteriorate. However, since the feeding speed of the inlet pipe 5 remains constant, the flow rate remains relatively constant. As the pressure inside the lower chamber 3 increases, the liquid level in the siphon tube 7 continues to rise. When the liquid level inside the siphon tube 7 reaches its maximum, it will flow downwards from its bend, creating a siphon effect. This causes the dye liquid inside the filter box 1 to flow back, while the dye liquid in the upper chamber 4 flows downwards and is drawn into the siphon tube 7. During this process, the filter screen 2 can be cleaned in reverse. After the siphoning is finished, the device returns to its original state and continues to filter, thus achieving automatic cleaning of blockages without the need for manual operation, improving convenience.

[0025] The highest point of the siphon tube 7 is higher than the height of the drain pipe 6, so when the filter plate 2 is filtering normally, the liquid level inside the siphon tube 7 will never reach its highest point. At the same time, the bottom end of the siphon tube 7 extends to the bottom of the filter box 1 to ensure the generation of the siphon effect. Multiple support frames are fixedly connected between the siphon tube 7 and the filter box 1 to support the siphon tube 7 and ensure its structural stability.

[0026] The outer surface of the upward extension of the siphon tube 7 is connected to the rupture tube 8, and the other end of the rupture tube 8 penetrates the upper surface of the filter box 1 and extends to the bottom of the inner cavity of the upper chamber 4.

[0027] A spherical filter screen 13 is fixedly connected to the bottom end of the destruction tube 8 and inside the upper cavity 4.

[0028] During the continuous water intake process generated by the siphon tube 7, when the liquid level inside the upper chamber 4 drops to the bottom of the destruction tube 8, air will enter the interior of the siphon tube 7 through the destruction tube 8, thereby breaking the siphon effect and causing the device to return to the filtration state.

[0029] The spherical filter 13 can prevent untreated liquid from flowing into the upper cavity 4 from the destruction tube 8, and its spherical design can also prevent the destruction tube 8 from becoming clogged to some extent.

[0030] A return pool 9 is provided at the bottom of the siphon 7.

[0031] A circulation tank 10 is installed at the bottom of the drain pipe 6.

[0032] The dye liquor containing impurities extracted through the siphon pipe 7 will be discharged back to the untreated dye liquor tank through the pipeline, while the dye liquor discharged through the drain pipe 6 will be recycled back to the dyeing machine through the pipeline of the circulation tank 10 for printing and dyeing processing.

[0033] A solenoid valve 12 is installed on the inlet pipe 5, and a sensor is installed on the downward bend of the siphon pipe 7.

[0034] The sensor is a fluid sensor. When the siphon pipe 7 generates a siphon effect, the sensor will sense the fluid flow in the pipe and transmit a signal to the main control. The main control controls the solenoid valve 12 to close and stop feeding the filter box 1, thereby accelerating the backflow rinsing speed and avoiding affecting the overall operating efficiency.

[0035] Since the device cannot filter during the backflow rinsing process, multiple devices can be set up in a system to perform filtration operations, and multiple devices can be controlled to perform backflow rinsing at different times.

[0036] Both the sensor and the solenoid valve 12 are mature existing technologies, and their structures will not be described in detail here.

[0037] Multiple support legs 11 are vertically fixedly connected to the bottom of the filter box 1, and a reinforcing rod is fixedly connected between every two adjacent support legs 11.

[0038] Multiple supporting legs 11 all provide support.

[0039] In operation, the dye liquor is fed into the lower chamber 3 of the filter box 1 through the inlet pipe 5. Once the lower chamber 3 is full, the dye liquor level rises and passes through the filter screen 2 into the upper chamber 4. During this process, impurities in the dye liquor are filtered by the filter screen 2. When the upper chamber 4 is also full, the filtered dye liquor is discharged through the drain pipe 6 into the circulation system, thus achieving a filtration effect. However, as the filter screen 2 continues to filter, the amount of impurities adhering to it increases, causing its filtration effect to slow down and the passage of dye liquor to deteriorate. However, since the feeding speed of the inlet pipe 5 remains constant, the flow rate remains relatively constant. As the pressure inside the lower chamber 3 increases, the liquid level in the siphon tube 7 continues to rise. When the liquid level inside the siphon tube 7 reaches its maximum, it will flow downwards from its bend, creating a siphon effect. This causes the dye liquid inside the filter box 1 to flow back, while the dye liquid in the upper chamber 4 flows downwards and is drawn into the siphon tube 7. During this process, the filter screen 2 can be cleaned in reverse. After the siphoning is finished, the device returns to its original state and continues to filter, thus achieving automatic cleaning of blockages without the need for manual operation, improving convenience.

[0040] Compared with related technologies, the dye liquor circulation filtration device provided by this utility model has the following beneficial effects: The device, by setting up a filter box 1 and a siphon pipe 7, allows the dye liquor to be transported from the inlet pipe 5 into the lower chamber of the filter box 1. Once the lower chamber 3 is full, the dye liquor level rises and passes through the filter screen 2 into the upper chamber 4. During this process, impurities in the dye liquor are filtered by the filter screen 2. When the upper chamber 4 is also full, the filtered dye liquor is discharged through the drain pipe 6 into the circulation system. As the filter screen 2 continues to filter, the amount of impurities adhering to it increases, leading to… As the filtration process slows down, the flow of dye liquor becomes less efficient, causing the liquid level in the siphon tube 7 to rise continuously. When the liquid level inside the siphon tube 7 reaches its maximum, it begins to flow downwards from its bend, creating a siphon effect. This causes the dye liquor inside the filter box 1 to flow back, while the dye liquor in the upper chamber 4 flows downwards and is drawn into the siphon tube 7. During this process, the filter screen 2 is cleaned in reverse. After the siphoning process ends, the device returns to its original state and continues filtration, thus achieving automatic cleaning of blockages without the need for manual operation, improving convenience.

[0041] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
