Description

Technical Field

[0001] This invention relates to the field of cashmere wastewater treatment technology, specifically to a wastewater treatment device and method for cashmere dyeing and processing. Background Technology

[0002] Cashmere fabric is a type of fabric. During the dyeing and printing process, a certain amount of production wastewater is discharged. In order to protect and improve the environment, wastewater treatment equipment is usually used for treatment.

[0003] The device for treating wastewater from the dyeing and printing of cashmere fabrics disclosed in CN202221848274.2 includes a wastewater treatment tank. The top of the wastewater treatment tank is provided with a receiving plate. The top of the receiving plate is provided with a groove. A filter frame is placed on the inner wall of the groove. A filter screen is fixedly installed on the inner wall of the filter frame. Multiple connecting rods are symmetrically installed at the bottom of the filter screen. The outer walls of the multiple connecting rods are threaded with screw rings. The outer walls of the multiple screw rings are symmetrically connected with hooks.

[0004] While the aforementioned treatment device can wrap cashmere in wastewater using connecting rods, screw rings, and hooks, its collection range for cashmere treatment is small, and its treatment effect is poor. Furthermore, manual processing of the cashmere wrapped on the hooks is required later, increasing labor intensity and making it cumbersome to use. Therefore, we propose a wastewater treatment device and method for cashmere dyeing processing. Summary of the Invention

The jacking element is located inside several groups of winding sheets. Each group of winding sheets has a wedge-shaped block that cooperates with the jacking element on the side facing the jacking element. The wedge block is driven by the jacking element to move the winding sheet outward. The end of the winding sheet facing the rotating cylinder is slidably connected to the outer end of the connecting cylinder. An elastic connecting element is provided between the winding sheet and the rotating cylinder to drive the winding sheet to return to its original position.

[0022] A further improvement is that the winding claw device further includes:

The sealing plate II is connected to the bracket by an elastic element. The end of the sealing plate II away from the bracket is provided with a contact rod for contacting the connecting frame.

[0025] A further improvement is that the adsorption component includes:

[0026] A collection seat is located inside the housing and is movably connected and communicates with the lower end of the hollow tube.

[0037] A method for treating wastewater from cashmere dyeing processes, utilizing the aforementioned wastewater treatment equipment, includes the following steps:

[0038] S1: The wastewater from the cashmere dyeing process flows downward through the filter screen into the wastewater treatment tank. The drive device drives the rotating drum to rotate. When the rotating drum rotates, it drives the inner rotating rod to rotate through the transmission component. When the inner rotating rod rotates, it drives the winding claw device to rotate and wind the cashmere in the wastewater.

[0039] S2: After processing in step S1, the wastewater in the wastewater treatment tank is discharged through the outlet pipe.

[0040] Compared with the prior art, the beneficial effects of the present invention are:

[0041] This invention, through the driving device driving the rotating cylinder to rotate circumferentially within the wastewater treatment tank, also enables the winding claw device to rotate circumferentially and simultaneously under the action of the transmission component. This allows the cashmere in the wastewater to be wound around its outer wall, resulting in a large collection range and good treatment effect for the cashmere. Furthermore, in the later stages of operation, the driving device causes the winding plates in the winding claw device to move outward, thereby detaching the cashmere wrapped around the outer wall of the winding claw device and simultaneously sucking it into the collection seat, completing the automatic collection and treatment. This greatly reduces the intensity of manual labor and is convenient to use. Attached Figure Description

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example 1

[0050] Please see the appendix Figure 1

[0051] A wastewater treatment device for cashmere dyeing processing includes a wastewater treatment tank 1, a filter screen 2 installed on the wastewater treatment tank 1, and an outlet pipe 3 connected to the wastewater treatment tank 1. The filter screen 2 can be detachably installed on the top of the wastewater treatment tank 1 using a bolt-type structure.

[0052] A rotating cylinder 4 is installed vertically inside the wastewater treatment tank 1 and below the filter screen 2 via a bearing. The rotating cylinder 4 is driven to rotate by a drive device 5 located at the bottom of the wastewater treatment tank 1. An inner rotating rod 6 is installed vertically inside the rotating cylinder 4 via a bearing. A transmission component is inserted into the lower end of one side of the rotating cylinder 4 to drive the inner rotating rod 6 to rotate when the rotating cylinder 4 rotates.

[0053] The outer wall of the rotating cylinder 4 is fitted with several sets of winding claw devices 7 that are connected to the inner rotating rod 6 from top to bottom. The winding claw devices 7 are used to rotate and wind the cashmere in the wastewater when the inner rotating rod 6 rotates. With this arrangement, the cashmere in the wastewater can be removed.

[0054] Please see the appendix Figure 2

[0055] Preferably, the driving device 5 in this embodiment includes:

[0056] The casing 51 is located at the bottom of the wastewater treatment tank 1;

[0057] Hollow tube 52, one end of which is located inside shell 51, and the other end of which movably passes through shell 51 and wastewater treatment tank 1 and is connected to the bottom of rotating cylinder 4; bearings are provided at the connection between hollow tube 52 and shell 51 and wastewater treatment tank 1; and,

[0058] A rotary motor 53 is located on one side of the hollow tube 52 and inside the housing 51. The rotary motor 53 is connected to the hollow tube 52 by means of transmission, such as a gear set (including two sets of meshing gears) or a sprocket drive set (including sprockets or chains).

[0059] When the rotary motor 53 is working, the hollow tube 52 drives the rotating cylinder 4, and the rotating cylinder 4 drives the winding claw device 7 to wind the cashmere in the wastewater.

[0060] Please see the appendix Figure 3

[0061] Preferably, the transmission component in this embodiment includes:

[0062] Hollow seat 8, one end of which is inserted into the lower end of the outer wall of the rotating cylinder 4 and movably sleeved on the outside of the inner rotating rod 6; and,

[0063] Roller assembly 10 is rotatably located at one end inside the hollow seat 8. Roller assembly 10 includes rollers and roller shafts. The rollers in roller assembly 10 slide against the inner wall of wastewater treatment tank 1. The roller shafts of roller assembly 10 are connected to the inner rotating rod 6 through a transmission, for example, by using a chain drive assembly.

[0064] When the rotating cylinder 4 rotates, it drives the hollow seat 8, and then the rollers of the roller assembly 10 rub against the inner wall of the wastewater treatment tank 1, causing the roller shaft to rotate. The roller shaft drives the inner rotating rod 6 to rotate.

[0065] Please see the appendix Figure 4 -Appendix Figure 5

[0066] Preferably, the winding claw device 7 in this embodiment includes:

[0067] A connecting cylinder 71 is rotatably inserted into the outer wall of the rotating cylinder 4 via bearings, and its inner end is hollow. A connecting frame 72 is provided at the inner end of the connecting cylinder 71. The connecting frame 72 is, for example, cross-shaped or straight. The inner end of the connecting frame 72 is connected to the inner rotating rod 6 via a transmission component. This transmission component includes, for example, a shaft whose one end is connected to the inner end of the connecting frame 72 and is coaxial with the connecting cylinder 71, and a set of bevel gears (including several meshing sets of bevel gears) that connects one end of the shaft to the inner rotating rod.

[0068] The winding sheet 73 is provided in several groups and is arranged horizontally in a ring array at the outer end of the connecting cylinder 71. It rotates with the connecting cylinder 71 and then winds the cashmere in the area it is in.

[0069] Preferably, the winding claw device 7 in this embodiment further includes:

[0070] The diverter tubes 710 are provided in several groups, all located on the inner wall of the rotating cylinder 4. The diverter tubes 710 on the same side are rotatably connected to the inner end of the connecting cylinder 71 in the multiple groups of winding claw devices 7 on the same side. That is, a vertical row of winding claw devices 7 is rotatably connected to a corresponding diverter tube 710. Specifically, the connecting cylinder 71 and the shaft in the transmission component are provided with bearings at the connection points with the diverter tubes 710. The lower end of the diverter tube 710 is connected to the hollow tube 52.

[0071] The adsorption component 9 is disposed inside the housing 51 and communicates with the bottom end of the hollow tube 52. When the adsorption component 9 is in operation, air in the diversion tube 710 is extracted, thereby creating a negative pressure in the connecting cylinder 71; and,

[0072] The movable plate 77 is movably disposed in the inner cavity of the connecting cylinder 71, and its outer diameter is adapted to the inner diameter of the connecting cylinder 71. When the adsorption assembly 9 is working, the movable plate 77 moves in the direction of the inner rotating rod 6 in the connecting cylinder 71 under the action of negative pressure.

[0073] One side of the movable plate 77 is connected to the inner wall of the rotating cylinder 4 via an elastic element, such as a spring. The outer end of the movable plate 77 is connected to a pusher 76 via a support rod that passes through the outer end of the rotating cylinder 4. The pusher 76 is located inside several sets of winding plates 73. The outer wall of the pusher 76 can be fitted with balls that slide against the inner wall of the winding plates 73. Each of the several sets of winding plates 73 has a wedge block 75 that cooperates with the pusher 76 on the side facing the pusher 76. The distance between the inclined surface of the wedge block 75 near the inner rotating rod 6 and the inner wall of the winding plate 73 is greater than the distance between the other end of the wedge block 75 and the inner wall of the winding plate 73, i.e., point a > point b.

[0074] The wedge block 75 is driven by the pusher 76 to move the winding strip 73 outward. The outward movement of the winding strip 73 can cause the cashmere wound on several sets of winding strips 73 to detach from the winding strip 73.

[0075] The end of the winding sheet 73 facing the rotating cylinder 4 is slidably connected to the outer end of the connecting cylinder 71. The winding sheet 73 and the connecting cylinder 71 can be slidably connected by a slide rail and a slider. An elastic connector 74 is provided between the winding sheet 73 and the rotating cylinder 4 to drive the winding sheet 73 to reset inward. The elastic connector 74 is, for example, an elastic telescopic rod. When the adsorption assembly 9 stops working, the moving plate 77 resets under the action of the elastic member, and at the same time, the elastic connector 74 drives the winding sheet 73 to reset.

[0076] Preferably, the winding claw device 7 in this embodiment further includes:

[0077] The adsorption port is provided in several groups, all located at the outer end of the connecting cylinder 71. A matching sealing plate 78 is provided inside each adsorption port. The sealing plate 78 is connected to the movable plate 77 via a bracket. When the adsorption assembly 9 is not working, the sealing plate 78 is positioned inside the adsorption port, making it difficult for wastewater to enter the connecting cylinder 71 through the adsorption port. The aforementioned bracket, for example, has a U-shaped vertical cross-section; and...

[0078] The flow port has a T-shaped vertical cross section and is located on the movable plate 77 and inside the bracket. The flow port is provided with a matching sealing plate 79. The sealing plate 79 is connected to the bracket by an elastic element. The end of the sealing plate 79 away from the bracket is provided with a contact rod for contacting the connecting frame 72.

[0079] Specifically, after the wastewater is discharged from the outlet pipe 3, the adsorption component 9 is activated, the moving plate 77 moves toward the connecting frame 72, and then drives the sealing plate 78 to detach from the adsorption port. After the contact rod contacts the connecting frame 72, the moving plate 77 continues to move, which will cause the sealing plate 79 to detach from the flow port. Then, a negative pressure adsorption force is generated at the flow port and the adsorption port, which causes the cashmere quilt wrapped at the winding sheet 73 to be sucked into the adsorption component 9.

[0080] Preferably, the adsorption component 9 in this embodiment includes:

[0081] The collection seat 91 is located inside the housing 51 and is movably connected and communicates with the lower end of the hollow tube 52, that is, a bearing is provided at the connection between the collection seat 91 and the hollow tube 52.

[0082] The collection seat 91 is provided with a partition plate to divide the inner cavity of the housing 51 into a collection cavity 95 and an assembly cavity located on both sides of the partition plate;

[0083] The induced draft fan 96 is mounted on and connected to the collection base 91. The induced draft fan 96 is prior art and includes a housing and an induced draft impeller, which will not be described in detail here.

[0084] A filter collection component 93 is disposed inside the collection seat 91 and located between the input end of the blower 96 and the lower end of the hollow tube 52. It is used to collect cashmere. One end of the filter collection component 93 can be movably inserted through the side wall of the collection seat 91 and the housing 51 to collect the processed cashmere. The filter collection component 93 includes, for example, a plate with a T-shaped vertical cross section. A rectangular opening is opened on the outer wall of the plate inside the collection cavity 95. A filter is provided on the inner wall of the rectangular opening. In this way, the processed cashmere can be intercepted from entering the blower 96, and it is also convenient to pull out the plate for cashmere collection.

[0085] A vent pipe 92 extends through the side wall of the housing 51 at one end and connects to the collection seat 91 at the other end. A solenoid valve is installed inside the vent pipe 92; during normal use, the solenoid valve is in the open position.

[0086] The drive unit, located inside the assembly cavity, is used to drive the induced draft fan 96 to work and to close the solenoid valve.

[0087] Preferably, the driving component in this embodiment includes:

[0088] The movable sleeve 97 is slidably sleeved on the output end of the rotary motor 53 and located in the assembly cavity. The outer wall of the movable sleeve 97 is provided with a protrusion 99. The movable sleeve 97 can be slidably connected with the vertical groove opened at the output end of the rotary motor 53 by means of a slider, so that it can move up and down relative to the output end of the rotary motor 53 and rotate with the output end of the rotary motor 53.

[0089] The docking cylinder 98 is rotatably disposed in the assembly cavity. The top of the docking cylinder 98 has a groove for the insertion of the movable sleeve 97. The inner wall of the groove has several sets of protrusions 2 that cooperate with protrusion 1 99. The bottom end of the docking cylinder 98 is connected to the impeller shaft of the induced draft fan 96. After the docking cylinder 98 enters the groove, when it rotates, it can abut against protrusion 2 through protrusion 1 99, and then protrusion 2 drives the induced draft fan 96 to work.

[0090] A magnetic bearing seat 910 is sleeved on the outer wall of the movable sleeve 97 and slidably connected to a guide seat 912 located on the inner wall of the collecting seat 91. The lower end of the guide seat 912 is provided with an electromagnetic adsorption component 911 that is energized to attract the magnetic bearing seat 910 downward, causing the movable sleeve 97 to enter the groove. The electromagnetic adsorption component 911 is, for example, an electromagnetic block. When the electromagnetic adsorption component 911 is energized, the magnetic bearing seat 910 drives the movable sleeve 97 to move downward.

[0091] The L-shaped frame 913 has one end extending through the top of the guide seat 912 and connected to the magnetic bearing seat 910, and the other end equipped with a sensor 94 for contacting the top of the guide seat 912. The sensor 94, for example, is a pressure sensor, electrically connected to an external controller. When the magnetic bearing seat 910 moves downward to a preset position and contacts the top of the guide seat 912, the sensor 94 sends a control signal to the external controller, which then controls the solenoid valve to close. When the electromagnetic adsorption component 911 is energized, the L-shaped frame 913 moves downward with the magnetic bearing seat 910, thereby contacting the sensor 94, thus closing the solenoid valve and stopping airflow through the vent pipe 92. When the electromagnetic adsorption component 911 is de-energized, the solenoid valve opens, allowing airflow through the vent pipe 92, so that structures such as the moving plate 77 and the winding sheet 73 can be reset.

[0092] A return spring, connecting the L-shaped bracket 913 and the guide seat 912, is used to drive the magnetic bearing seat 910 to reset when the electromagnetic adsorption component 911 is de-energized.

[0093] A method for treating wastewater from cashmere dyeing processes, utilizing the aforementioned wastewater treatment equipment, includes the following steps:

[0094] S1: The wastewater from the cashmere dyeing process enters the wastewater treatment tank 1 through the filter screen 2. The drive device 5 drives the rotating drum 4 to rotate. When the rotating drum 4 rotates, it drives the inner rotating rod 6 to rotate through the transmission component. When the inner rotating rod 6 rotates, it drives the winding claw device 7 to rotate and wind the cashmere in the wastewater.

[0095] S2: After processing in step S1, the wastewater in the wastewater treatment tank 1 is discharged through the outlet pipe 3.

[0096] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
