Description

Technical Field

[0001] This utility model relates to the field of dyeing and printing pollution treatment, and more specifically, it relates to a cleaning and collection mechanism for dyeing and printing equipment. Background Technology

[0002] In the dyeing and printing process, singeing, brushing, and raising processes can easily generate debris. To ensure dyeing and printing quality and equipment lifespan, this debris needs to be cleaned. During the cleaning process, these lightweight debris are easily lifted and float in the air. Therefore, it is often necessary to collect these debris through air filters. Existing filters generally use fans and filter screens to collect debris. The fan drives the airflow through the filter screen, and the debris is blocked by the filter screen, thus achieving debris collection. However, the size of the debris varies, while the specifications of the filter screen are fixed. It is necessary to replace the filter screen or install multiple filter screens of different specifications at the same time to achieve adaptive adjustment. Moreover, the cleaning of the filter screen is also relatively frequent, which is time-consuming and labor-intensive.

[0003] This utility model provides another technical solution to this technical problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cleaning and collection mechanism for printing and dyeing equipment.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cleaning and collection mechanism for printing and dyeing equipment, comprising a housing, a water inlet at the top of the housing, a water outlet at the bottom of the housing, an air inlet on the front of the housing, and an air outlet on the back of the housing, two spray pipes communicating with the water inlet inside the housing, a first filter plate and several second filter plates fixedly connected inside the housing, the first filter plate having a zigzag cross-section, and gaps for airflow at the turning points of the first filter plate, the spray pipes being located at the top of the first filter plate, two spray pipes being located on both sides of the first filter plate respectively, the spraying direction of the spray pipes being vertically downward, and a horizontally oriented guide groove being provided on the second filter plate, one end of the guide groove being connected to a guide connector, the guide connector being connected to the water inlet through a water pipe.

[0006] The present invention is further configured such that: the first filter plate is composed of several guide plates, adjacent guide plates are combined into a figure-eight structure, and one end of the guide plate near another guide plate is provided with a connecting piece with an L-shaped cross section, and the connecting piece is detachably connected to the two adjacent guide plates.

[0007] The present invention is further configured such that the sum of the lengths of the connecting pieces in the same row is less than the width of the guide plate.

[0008] The present invention is further configured such that the top of the side wall of the guide channel near the air outlet is lower than the top of the side wall of the other side of the guide channel.

[0009] The present invention is further configured such that: the number of flow guide grooves on any of the second filter plates is greater than one, and the flow guide grooves are linearly arranged on the second filter plates along the vertical direction.

[0010] The present invention is further configured such that a support frame is provided between adjacent guide channels.

[0011] In summary, this utility model has the following beneficial effects: the combined design of the guide plate and the spray pipe improves the debris capture rate through the dual effects of mechanical interception and water washing, and slows down the kinetic energy of the debris, making it easier for the debris to be captured by the water curtain at the second filter plate. The captured debris is collected with the water flow and discharged from the outlet. The wetted debris will not be stirred up and is easy to handle. At the same time, both the first filter plate and the second filter plate are continuously flushed by water flow, reducing the maintenance frequency. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example: A cleaning and collection mechanism for printing and dyeing equipment, such as... Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown, the main body of the collection mechanism is a shell 1 integrally welded from 304 stainless steel. A water inlet 2 is located on the top surface of the shell 1 for connecting to an external water supply system, and four water outlets 3 are linearly distributed at the bottom for connecting to drainage pipes, ensuring that even in the event of temporary blockage, there are backup water outlets 3 to prevent downtime. A rectangular air inlet 4 is opened on the front of the shell 1 for connecting to a pipe transporting dust-laden gas, and a rectangular air inlet 4 is opened on the back for connecting to a fan. The areas of the air inlets 4 and 5 are both smaller than the cross-sectional area of ​​the shell 1, allowing the dust-laden gas to diffuse within the shell 1 and increasing the probability of capturing debris. The first filter plate 7 is composed of multiple detachable guide plates 12 spliced ​​together. Adjacent guide plates 12 are fixed by L-shaped connecting pieces 13, forming a continuous figure-eight distribution between the guide plates 12. A gap 9 of 5-8 mm is maintained between the guide plates 12 for airflow. Two spray pipes 6 are installed on the top two sides of the first filter plate 7, using atomizing nozzles with a 0.5 mm aperture to spray vertically downwards. The water pressure in the spray pipe 6 is controlled at 0.3-0.5 MPa, forming a dense water curtain to capture large particles of debris in the air. The water flows downward along the first filter plate 7, reducing the frequency of maintenance. The flow area of ​​the inlet 2 is larger than that of the spray pipe 6, ensuring sufficient water in the spray pipe 6 and the subsequent guide channel 10.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown, following the airflow direction within the housing 1, three parallel second filter plates 8 follow the first filter plate 7. Each second filter plate 8 has two horizontally arranged guide channels 10. The walls of the guide channels 10 near the air outlet 5 are lower, forming an overflow structure. The guide channels 10 are connected to the water inlet 2 via guide connectors 11 and water pipes connected to the guide connectors 11. Water flows into the guide channels 10 and eventually overflows from the second filter plate 8 near the air outlet 5, forming a water curtain. The two vertically distributed guide channels 10 form two water curtains, ensuring the coverage of the water curtain. A stainless steel support frame 14 is installed between adjacent guide channels 10 to ensure structural strength.

[0022] During operation, the negative pressure generated by the fan forces air containing debris into the housing 1 through the air inlet 4. The airflow first passes through the first filter plate 7, where some debris impacts the surface of the guide plate 12 under inertia and is washed to the bottom by the water flow from the top spray pipe 6. The remaining debris enters the space between the second filter plates 8 with the airflow. After passing through the first filter plate 7, the kinetic energy of the airflow decreases, making it easier for the debris to be absorbed and settled by the water overflowing from the guide channel 10. The purified air is finally discharged from the air outlet 5. The debris is automatically discharged with the water flow, and the debris wetted by the water flow is no longer easily stirred up, making it easy to collect and process. The water flow can be recycled after treatment.

[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
