Description

Technical Field

[0001] This utility model belongs to the field of dyeing machine technology, and specifically relates to a filter material device for a dyeing machine. Background Technology

[0002] The following technical pain points are commonly found in the dye liquor filtration stage of current dyeing machines: Traditional equipment usually uses a single filter, which requires shutdown for cleaning or replacement once it becomes clogged, leading to production interruption. Especially in continuous production, downtime for maintenance will significantly reduce efficiency and increase costs; filtration and dyeing efficiency conflict, as the dye liquor filtration process is often carried out simultaneously with the dyeing process. Increased filtration resistance will slow down the flow rate of the dye liquor, affect the uniformity of dyeing, and reduce dyeing efficiency.

Therefore, a filter media device for dyeing machines that facilitates filter replacement without compromising dyeing efficiency is needed to solve these problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are: (1) This scheme connects two delivery pipelines in parallel through a solenoid valve. Each delivery pipeline is equipped with a filter. The direction of the dye liquor flow is adjusted by controlling the solenoid valve.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] Reference Figure 1 and Figure 2As shown, this utility model provides the following technical solution: a filter material device for a dyeing machine, including a first conveying pipe 2 and a second conveying pipe 4. The conveying pipe is connected to an external dyeing container for conveying dye liquor. A first filter component 3 is connected through the middle of the first conveying pipe 2, and a second filter component 5 is connected through the middle of the second conveying pipe 4. The inner core filter component can adopt common filter equipment in the prior art. A first solenoid valve 6 is fixed at the upper end of the first conveying pipe 2, and the first solenoid valve 6 is connected through the upper end of the second conveying pipe 4. The dyeing flow direction is adjusted by the solenoid valve. Specifically, by setting up two delivery pipelines and two sets of filter components, when filtering the dye, the operator adjusts the dye flow direction through the solenoid valve. When the first filter component 3 is blocked (which can be monitored with the help of the existing blockage alarm system), the operator can pass the dye into the second delivery pipeline 4 through the solenoid valve. At this time, the operator can disassemble, clean or replace the first filter component 3 without stopping the machine, without affecting the dyeing efficiency.

[0020] Reference Figure 2 , Figure 3 and Figure 4 As shown, specifically, the first filter assembly 3 includes a fixed base 31, a filter 32, and a telescopic cylinder 33. The fixed base 31 is fixedly connected to the middle of the first conveying pipe 2 and is used to install and fix the filter 32. The filter 32 is fixed to the bottom of the fixed base 31. It adopts a common filter component in the prior art. The telescopic cylinder 33 is sleeved on the outside of the filter 32. It is made of elastic silicone material and can be elastically compressed. The lower end of the telescopic cylinder 33 is connected to the first conveying pipe 2. The filter 32 filters the dye solution passing through the first conveying pipe 2. A compression ring 331 is fixed at the top, and a rigid cylinder 333 is sleeved on the outside of the compression ring 331. An internal threaded ring 335 is fixed at the top of the rigid cylinder 333, and an external threaded ring 311 is fixed at the bottom edge of the fixed seat 31. The internal threaded ring 335 is threaded to the outside of the external threaded ring 311. A turntable 34 is fixedly connected to the outside of the rigid cylinder 333. The threaded connection method is simple. The telescopic cylinder 33 is tightly sleeved on the outside of the filter 32, which facilitates the smooth introduction of the filtered dye liquor into the lower pipeline. The first filter assembly 3 and the second filter assembly 5 have the same structure. Specifically, the telescopic cylinder 33 is sealed to the outside of the filter 32 by means of a threaded connection. When the filter 32 needs to be replaced later, the operator only needs to turn the turntable 34 to disengage the threaded connection, and then compress the telescopic cylinder 33 to expose the filter 32. It is easy to disassemble and assemble.

[0021] Reference Figure 3 and Figure 4As shown, specifically, the compression ring 331 is located below the external threaded ring 311, and a first sealing ring 332 is fixed to the top of the compression ring 331. When the threaded structure is tightened, the compression ring 331 presses against the bottom of the external threaded ring 311, and is sealed by the first sealing ring 332. A second sealing ring 334 is fixed to the bottom edge of the rigid cylinder 333. The second sealing ring 334 is located below the compression ring 331. After the rigid cylinder 333 is tightened, it is sealed by the second sealing ring 334. A third sealing ring 312 is provided on the outside of the external threaded ring 311. The third sealing ring 312 is located above the internal threaded ring 335. The first sealing ring 332, the second sealing ring 334 and the third sealing ring 312 are all made of elastic silicone, forming a multi-layer sealing structure. Through the multi-layer sealing structure, the sealing performance of the filter assembly is improved, while not affecting the easy disassembly function. Example

[0022] In another embodiment of this solution, refer to Figure 1 and Figure 2 As shown, specifically, a storage tank 1 is connected to the bottom of the first conveying pipe 2 and the second conveying pipe 4. The volume of the storage tank 1 is 1.2-1.5 times the amount of dye solution required for one dyeing session to prevent dye solution overflow. The storage tank 1 includes an inner storage layer 11 and a preheating outer layer 12, which are fixedly connected by a connecting block 13. The inner storage layer 11 is connected to the first conveying pipe 2 and the second conveying pipe 4 to store the filtered dye solution. The preheating outer layer 12 is connected to an external heat recovery pipeline. Heat recovery is quite common, and to avoid... To avoid wasting heat energy, most dyeing machines usually recover the discharged heat energy, but this is not fully utilized. This solution uses the recovered heat energy to preheat the dye liquor in the inner storage layer 11. The top edge of the preheating outer layer 12 is connected to the inlet pipe 15, and the bottom edge of the preheating outer layer 12 is connected to the outlet pipe 16 to facilitate circulating preheating. The bottom edge of the inner storage layer 11 is connected to the third conveying pipe 17 to convey the dye liquor into the heating unit. The third conveying pipe 17 is fixed with a second solenoid valve 7, which can discharge the dye liquor in subsequent operations. Specifically, the filtered dye solution is pre-stored in the storage tank 1 to avoid the impact of simultaneous filtration on dyeing efficiency. At the same time, the dye solution is preheated by recovering heat energy to reduce additional heating energy consumption and subsequent heating time, thereby further improving dyeing efficiency and enhancing the overall practicality of the equipment.

[0023] Reference Figure 2 As shown, specifically, a temperature sensor 14 is fixed to one side wall of the preheating outer layer 12. The probe of the temperature sensor 14 penetrates the inner liquid storage layer 11 to monitor the temperature of the dye solution in real time after preheating.

[0024] The working principle and usage process of this utility model are as follows: Before dyeing, the dye liquid is pre-transported and stored inside the storage tank 1 through the first conveying pipe 2. When the dye liquid is transported through the first conveying pipe 2, it is filtered by the filter 32 of the first filter assembly 3. The dye liquid is pre-stored in the storage tank 1 to avoid the filtration affecting the efficiency during subsequent dyeing. When the filter 32 at the first conveying pipe 2 is blocked, the operator operates the first solenoid valve 6 to pass the dye liquid into the inside of the second conveying pipe 4. The dye liquid is filtered by the filter assembly on the second conveying pipe 4. At the same time, the operator can rotate and remove the rigid cylinder 333 of the first filter assembly 3 to expose the inner filter 32 for easy replacement. The machine does not need to be stopped when replacing the filter. In addition, when the dye solution is pre-stored inside the storage tank 1, a preheating outer layer 12 is sleeved on the outside of the inner storage layer 11. The recovered heat energy can be introduced into the inner side of the preheating outer layer 12 through the external heat recovery pipeline to preheat the dye solution inside the inner storage layer 11, thereby reducing the subsequent additional heating energy consumption. When dyeing, the solenoid valve at the bottom of the storage tank 1 is opened to release the dye solution.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
