Description

Technical Field

[0001] The invention relates to the field of textile cotton recycling, in particular to a textile cotton purification and recycling device. Background Art

[0002] Cotton spinning is the process of processing cotton fibers into cotton yarn and thread. This process is also applicable to the production of cotton-based synthetic yarn, medium- and long-staple yarn, and blends of cotton and other fibers. Cotton fabrics offer excellent wearability, are inexpensive, and the spinning process is relatively simple, making them a leading industry in the textile industry. Cotton products are used as raw materials in cotton spinning workshops, and during their use, they produce large amounts of lint. This working environment is extremely detrimental to the health of workers. Furthermore, the accumulation of lint in cotton spinning equipment can affect its normal operation, shorten its lifespan, and increase cotton spinning costs.

[0003] For example, Chinese patent CN108744781B provides a textile lint purification and recovery device, comprising a water tank, the top surface of which is an inclined surface, the top of which is connected to a vertical box, one side of which is connected to a dust hood, and the other side of which is connected to an exhaust device. The present invention has a simple structure, and the first motor and the second motor are started separately. The first motor drives the fan blades to rotate, forming a negative pressure in the dust hood, sucking in lint from the surrounding air and dropping it on the filter belt. The second motor drives the active roller to rotate counterclockwise. The active roller and the rotating drum cooperate to drive the filter belt to rotate counterclockwise, bringing the lint adsorbed thereon into the water. Under the action of buoyancy, the lint enters the lint discharge pipe along the inclined surface of the top of the water tank. At the same time, the filter belt drives the first bevel gear to rotate through the rotating drum and the chain. The first bevel gear meshes with the second bevel gear, driving the spiral blade shaft to rotate.

[0004] Most existing textile cotton filters filter cotton fibers into the filter element. On the one hand, the accumulation of cotton in the filter element will reduce air circulation and thus reduce the cotton cleaning efficiency. At the same time, the cotton in the filter element cannot be recycled, resulting in a waste of resources. On the other hand, the filter element is a consumable material and needs to be replaced frequently, resulting in a high cost of use. Summary of the Invention

[0005] Based on this, it is necessary to provide a textile cotton lint purification and recovery device to address the problem that the filter element of the current existing textile cotton lint filter accumulates cotton lint, which reduces air circulation, thereby reducing cotton lint cleaning efficiency and requiring frequent filter element replacement, resulting in high costs.

[0042] like Figure 1-8 As shown, a textile cotton lint purification and recovery device described in one embodiment includes: a cleaning shell 320, a motor 310, a main box 200, a filter system 100 and a spiral cleaning component 330, the filter system 100 includes a filter belt 110, a sealing plate 120 and a connecting pipe 130, the filter belt 110 moves under the drive of the motor 310, and sealing plates 120 are provided at both ends of the filter belt 110, and the filter belt 110 and the sealing plate 120 surround and form a chamber; the main box 200 includes a box body 210, a collection chamber 220 and an air pump 230, the collection chamber 220 is arranged in the box body 210 to collect cotton lint, and the air pump 230 is arranged in the box body 210, the vacuum pump 230 is connected to the chamber formed by the filter belt 110 and the sealing plate 120 through the connecting pipe 130. The vacuum pump 230 can draw the chamber formed by the connecting pipe 130, the filter belt 110 and the sealing plate 120 into a negative pressure, and the cotton wool floating in the air is adsorbed on the filter belt 110 through the internal and external pressure difference; the spiral cleaning component 330 rotates under the drive of the motor 310, and the cotton wool adsorbed on the filter belt 110 is cleaned up by the rotation of the spiral cleaning component 330 itself and the rotation of the filter belt 110, and the cotton wool is transported to the collection chamber 220 for unified collection through the spiral structure of the spiral cleaning component 330 itself.

[0043] Alternatively, the filter belt 110 is fixed, and sealing plates 120 are provided at both ends of the filter belt 110. The filter belt 110 and the sealing plate 120 surround a chamber, and the vacuum pump 230 pumps the chamber formed by the connecting pipe 130, the filter belt 110 and the sealing plate 120 into a negative pressure, so that the cotton wool floating in the air is adsorbed on the filter belt 110 through the internal and external pressure difference; the spiral cleaning component 330 itself can rotate and run along a preset track, thereby cleaning the cotton wool adsorbed on the filter belt 110, and transporting the cotton wool to the collection chamber 220 for unified collection through the spiral structure of the spiral cleaning component 330 itself.

[0044] By setting up a spirally arranged brush, the cotton wool adhering to the filter belt 110 can be cleaned and transported out of the shell at the same time; by setting up the filter belt 110 and the spiral cleaning component 330, the cotton wool can be cleaned from the filter belt 110 in time, and the cotton wool can be collected in a unified manner while ensuring the adsorption efficiency of the filter belt 110, thereby avoiding waste of resources.

[0045] like Figure 6 、 Figure 8 As shown, in some embodiments, a scraper 321 is provided on the cleaning shell 320 , and the spiral cleaning assembly 330 cleans away some of the cotton wool on the filter belt 110 , and the remaining cotton wool that is not cleaned away is cleaned away by the scraper 321 .

[0046] like Figure 6 、 Figure 7 、 Figure 10 As shown, in some embodiments, the spiral cleaning assembly 330 includes a hollow tube 331 and a hollow brush 332. One end of the hollow tube 331 is connected to the motor 310, and the other end is connected to the belt 370. The hollow brush 332 is arranged in a spiral shape on the hollow tube 331 along the axis of the hollow tube 331. Driven by the motor 310, the hollow brush 332 cleans the cotton wool attached to the filter belt 110.

[0047] like Figure 4 、 Figure 5 、 Figure 10 As shown, in some embodiments, the hollow brush 332 includes a water outlet 3321 and a water inlet 3322. Water is injected into the hollow tube 331 through the water inlet 360, then enters the hollow brush 332 through the water inlet 3322, and flows out through the water outlet 3321 to wet the filter belt 110 and cotton wool, thereby facilitating the attachment and cleaning of the cotton wool.

[0048] like Figure 5 、 Figure 7As shown, in some embodiments, the vibration cleaning assembly 340 cannot rotate under the restriction of the cleaning shell 320, but can move up and down. The vibration cleaning assembly 340 is used to clean the cotton wool adhered to the hollow brush 332 or between the hollow brushes 332.

[0049] like Figure 7 、 Figure 9 As shown, in some embodiments, the vibration cleaning assembly 340 includes a base 341, a connecting rod 342, a compression spring 343, a ratchet 345 and a cotton lint outlet 346; the connecting rod 342, the ratchet 345 and the cotton lint outlet 346 are all fixedly arranged on the base 341, and the comb is fixedly arranged on the connecting rod 342; the axis of the connecting rod 342 can be parallel to the axis of the base 341 or the axis of the connecting rod 342 can be set at a set angle to the axis of the base 341. Preferably, when the axis of the connecting rod 342 is set at a set angle to the axis of the base 341, the contact area between the comb on the connecting rod 342 and the hollow brush 332 is larger, so that the comb on the connecting rod 342 The comb has a larger cleaning area; one end of the base 341 is connected to the hollow tube 331 through the ratchet 345, and the other end is connected to the cleaning shell 320 through the compression spring 343; while the motor 310 drives the hollow tube 331 to rotate, under the joint action of the ratchet connection between the base 341 and the hollow tube 331 and the compression spring 343, the base 341 vibrates, and further the vibrating comb cleans the cotton fibers adhered to the hollow brush 332 that rotates through it, and at the same time transmits the vibration to the hollow brush 332, so that the hollow brush 332 throws out water mist under high-frequency vibration, humidifies a small area, thereby accelerating the falling of the cotton fibers and facilitating the collection of the cotton fibers.

[0050] like Figure 7 、 Figure 11 、 Figure 12 As shown, in some embodiments, the vibration cleaning assembly 340 also includes a baffle 344, which is fixedly arranged on the base 341. The hollow brush 332 will preferentially contact the baffle 344 during the rotation process, thereby causing the hollow brush 332 to be bent. As a result, when the hollow brush 332 passes over the baffle 344, the speed of the hollow brush 332 is the superposition of the speed of the elastic release of the hollow brush 332 and the linear speed brought by the rotation of the hollow tube 331 itself, and the baffle 344 is arranged before the hollow brush 332 contacts the filter belt 110, so that the elastically released hollow brush 332 just contacts the filter belt 110, so that the hollow brush 332 has a better cleaning effect on the filter belt 110.

[0051] like Figure 3 、 Figure 4 、 Figure 6As shown, in some embodiments, the motor 310 is disposed on the upper portion of the cleaning housing 320 , and the motor 310 directly drives the spiral cleaning assembly 330 to rotate, thereby driving the filter belt 110 to move through the belt 370 .

The hollow brush 332 is arranged in a spiral shape on the hollow tube 331 along the axis of the hollow tube 331. Driven by the motor 310, the hollow brush 332 cleans the cotton wool attached to the filter belt 110. Water is injected into the hollow tube 331 through the water inlet 360, and then enters the hollow brush 332 through the water inlet 3322. It flows out through the water outlet 3321 to wet the filter belt 110 and the cotton wool, thereby facilitating the attachment and cleaning of the cotton wool.

[0059] The vibration cleaning assembly 340 includes a base 341 , a connecting rod 342 , a compression spring 343 , a blocking rod 344 , a ratchet 345 and a cotton lint outlet 346 .
