Technical Field

[0001] The invention relates to the technical field of textile processing equipment, in particular to a textile cleaning and filtering device. Background Art

[0002] The processing of some textiles involves a cleaning step, during which liquid needs to be discharged. However, to ensure that the textiles are not discharged together, a filter is needed to block it. However, the filter is easily clogged by tiny textiles, resulting in poor drainage.

[0003] The existing solution is to increase the number of times the filter is cleaned and shorten the time interval for cleaning the filter. However, doing so will result in frequent downtime for maintenance, which is very cumbersome and time-consuming, and reduces the cleaning efficiency. Summary of the invention

[0005] Based on the above-mentioned purpose, the present invention provides a textile cleaning and filtering device, comprising a cleaning box for cleaning textiles; a discharge port, arranged on the cleaning box, for discharging cleaning liquid; a filter screen, arranged on the discharge port, to hinder the discharge of solids in the cleaning box; and a scraper assembly, arranged on the inner wall of the cleaning box, to periodically scrape the surface of the filter screen pointing to the inner side of the cleaning box, to clean the filter screen, and to maintain the permeability of the filter screen.

[0006] As a further improvement of the present application, the scraper assembly includes a drive motor, a drive rod, a mounting rod, two connecting rods, a pressure spring and a scraper body; one end of the drive rod is fixedly connected to the output shaft of the drive motor, and the drive rod is perpendicular to the output shaft of the drive motor; the two ends of the connecting rod are respectively connected to the drive rod and the mounting rod through a pin shaft; the two ends of the pressure spring are respectively connected to the drive rod and the mounting rod; the scraper body is connected to the mounting rod, one side of the scraper body is in contact with the surface of the filter, the pressure spring is in a compressed state, and the length of the connecting rod is greater than the distance between the drive rod and the mounting rod.

[0007] As a further improvement of the present application, the driving rod and the mounting rod are parallel to each other.

[0008] As a further improvement of the present application, the two connecting rods are parallel to each other.

[0009] As a further improvement of the present application, the filter screen is a cup-shaped structure, the mouth of which is connected to the discharge port, and the bottom of which contacts one side of the scraper body.

[0010] As a further improvement of the present application, the mouth of the filter is everted;

[0011] A plurality of threaded countersunk holes are arranged inside the cleaning box around the drain port;

[0012] The filter screen also includes a connecting ring, which is sleeved on the filter screen and connected to the threaded countersunk hole through bolts to press the outward-turned part of the mouth.

[0013] As a further improvement of the present application, an isolation cover is also provided on the discharge port, and the isolation cover covers the scraper assembly and the filter.

[0014] As a further improvement of the present application, the isolation cover is provided with large mesh holes, and the diameter of the large mesh holes is five to twenty times the diameter of the mesh holes of the filter screen.

[0015] Beneficial effects of the present invention: The present invention uses a scraper assembly to promptly remove the attachments on the filter surface, keeps the filter unobstructed, and extends the maintenance interval, effectively solving the technical problem that the existing filter device needs to be frequently shut down for maintenance, which is very cumbersome and time-consuming, and reduces the cleaning efficiency.

[0022] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0023] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

[0024] like Figure 1 As shown, a textile cleaning and filtering device comprises

[0025] A washing box 1, used for washing textiles;

[0026] A discharge port 2, provided on the cleaning box 1, for discharging cleaning liquid;

[0027] A filter screen 3 is provided on the discharge port 2 to prevent the solid in the cleaning tank 1 from being discharged;

[0028] The scraper assembly is arranged on the inner wall of the cleaning box 1, and periodically scrapes the surface of the filter screen 3 pointing to the inner side of the cleaning box 1 to clean the filter screen 3 and maintain the passability of the filter screen 3.

[0029] The scraper assembly can be used to promptly remove the attachments on the surface of the filter screen 3, thereby keeping the filter screen 3 unobstructed and extending the maintenance time interval.

[0030] To keep running, Figure 2As shown, the scraper assembly includes a driving motor 41, a driving rod 42, a mounting rod 43, two connecting rods 44, a pressure spring 45 and a scraper body 46; one end of the driving rod 42 is fixedly connected to the output shaft of the driving motor 41, and the driving rod 42 is perpendicular to the output shaft of the driving motor 41; the two ends of the connecting rod 44 are respectively connected to the driving rod 42 and the mounting rod 43 through a pin; the two ends of the pressure spring 45 are respectively connected to the driving rod 42 and the mounting rod 43; the scraper body 46 is connected to the mounting rod 43, one side of the scraper body 46 is in contact with the surface of the filter 3, the pressure spring 45 is in a compressed state, and the length of the connecting rod 44 is greater than the distance between the driving rod 42 and the mounting rod 43.

[0031] The pressure between the scraper body 46 and the filter screen 3 is maintained by the pressure of the pressure spring 45, thereby enhancing the cleaning ability.

[0032] The driving rod 42 and the mounting rod 43 are parallel to each other. In order to keep the mounting rod 43 in a basic state with the driving rod 42 during the movement, the two linkage rods 44 are parallel to each other.

[0033] In order to avoid excessive contact with the inner wall of the cleaning box 1, the filter screen 3 is a cup-shaped structure, the mouth of which is connected to the discharge port 2, and the bottom of which contacts one side of the scraper body 46. Such a protruding filter screen 3 avoids contact between the scraper body 46 and the inner wall of the cleaning box 1, reducing the running resistance.

[0034] like Figure 3 As shown, in order to enhance connectivity and facilitate replacement of filter screens 3 with different mesh sizes, the mouth of the filter screen 3 is turned outward; a number of threaded countersunk holes are provided inside the cleaning box 1 around the discharge port 2; the filter screen 3 also includes a connecting ring 6, which is sleeved on the filter screen 3 and connected to the threaded countersunk holes by bolts to press the turned-out part of the mouth.

[0035] In this way, the filter screen 3 with different mesh sizes can be easily replaced.

[0036] In order to enhance the permeability and avoid the textile covering the filter 3 which would significantly reduce the permeability, and also avoid the scraper assembly coming into contact with the textile which would damage the textile during operation, an isolation cover 5 is further provided on the discharge port 2, and the isolation cover 5 covers the scraper assembly and the filter 3.

[0037] In order to prevent the isolation cover 5 from becoming an obstacle to the filtering capacity, the isolation cover 5 is provided with large mesh holes, and the diameter of the large mesh holes is five to twenty times the diameter of the mesh holes of the filter screen 3.

[0038] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
