Description

Technical Field

[0001] This utility model relates to the field of dyeing and printing sludge treatment technology, specifically a dyeing and printing sludge dewatering device. Background Technology

[0002] Cotton packaged yarn is the yarn that falls from the spinning machine or twisting machine in the previous process. According to the requirements of the subsequent processes of yarn use in weaving factories, knitting factories, towel factories, etc., the yarn length is extended and defects and impurities on the yarn are removed. On the winding machine, it is rewound into a larger volume packaged yarn with or without edges, wound into a certain shape (such as conical or cylindrical), and with a certain winding density through grooved drums or rapidly reciprocating yarn guide hooks. During the dyeing process of cotton packaged yarn, a large amount of dyeing sludge is generated. This sludge is mainly composed of dyes, sizing agents, oils, auxiliaries, water, and some fibrous impurities. It has the characteristics of high organic content, easy to perish, and difficult to treat. If this sludge is not effectively treated, it will not only cause waste of resources, but also cause serious pollution to the environment.

[0022] 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.

[0023] Please see Figures 1-5 In this embodiment of the invention, a dewatering device for dyeing and printing sludge includes a base 300. Four support legs 310 are fixedly connected to the bottom surface of the base 300. A screening mechanism 200 and a spiral dewatering machine 400 are fixedly connected to the top surface of the support legs 310. A crushing and stirring mechanism 100 is fixedly connected to the top surface of the screening mechanism 200. The crushing and stirring mechanism 100 includes a stirring tank 110. A stirring shaft 111 is rotatably connected to the inner top surface of the stirring tank 110. The outer wall of the stirring shaft 111, etc. Several blades 112 are fixedly connected at an angle. A motor 113 is fixedly connected to the top surface of the mixing tank 110. The motor shaft of the motor 113 is connected to the top end of the mixing shaft 111. A feed hopper 114 is provided on the top surface of the mixing tank 110. A conveying pipe 115 is fixedly connected to the bottom surface of the mixing tank 110. A valve 116 is installed on the conveying pipe 115. A fixing ring 120 is fixedly fitted onto the outer wall of the mixing tank 110. Four fixing brackets 121 are fixedly connected to the outer wall of the fixing ring 120 at equal angles.

[0024] Specifically, the dyeing and printing sludge is fed into the mixing tank 110 from the feed hopper 114. The motor shaft of the drive motor 113 drives the mixing shaft 111, causing the mixing shaft 111 to rotate the blades 112. The rotating blades 112 crush the large particles in the sludge to facilitate subsequent screening and dewatering. During the crushing process, coagulant can be added into the mixing tank 110 from the feed hopper 114. The rotating blades 112 crush the sludge while mixing it with the coagulant. After the crushing and mixing are completed, the valve 116 is opened, allowing the sludge in the mixing tank 110 to enter the screening mechanism 200 through the conveying pipe 115 for screening. The screened sludge then enters the screw dewatering machine 400 for dewatering.

[0025] Example 1

[0026] like Figure 2-3As shown, in this embodiment, the screening mechanism 200 includes a screening box 210. The top surface of the screening box 210 is fixedly connected to the bottom ends of four fixed frames 121. The bottom end of the conveying pipe 115 is connected to the top surface of the screening box 210. Four connecting columns 212 are symmetrically fixed to the bottom surface of the screening box 210. The bottom ends of the four connecting columns 212 are all fixedly connected to the top surface of the base 300. A door 211 is rotatably connected to the opening near the front side of the screening box 210 via a hinge. Two sliding grooves are symmetrically opened on the two opposite inner sidewalls of the screening box 210. 214, two sliding grooves 214 are each slidably connected to a lifting plate 220. The opposite side walls of the two lifting plates 220 are each provided with an insertion groove. A screen plate 230 is slidably inserted into the two insertion grooves. The bottom surfaces of the two lifting plates 220 are symmetrically fixedly connected to a return spring 221. The other end of the return spring 221 is fixedly connected to the inner bottom surface of the screening box 210. A vibration motor 222 is fixedly connected to the bottom surface of the lifting plate 220. A feeding pipe 213 is provided on the bottom surface of the screening box 210. A rotating ring 215 is fixedly connected to the bottom end of the feeding pipe 213.

[0027] In this embodiment, the crushed sludge falls from the conveying pipe 115 onto the screen plate 230 inside the screening box 210. The vibration motor 222 is started, causing the lifting plate 220 to drive the screen plate 230 to vibrate, so that the screen plate 230 vibrates and screens the sludge on its surface, removing fine fibers, impurities and uncrushed large particles. The sludge that passes through the screen holes will enter the spiral dewatering machine 400 from the feeding pipe 213 at the bottom of the screening box 210 for subsequent dewatering. The impurities and large particles intercepted by the screen plate 230 can be removed by opening the box door 211 and sliding the screen plate 230 between the two lifting plates 220.

[0028] like Figure 2 and Figure 4-5As shown, in this embodiment, the spiral dewatering machine 400 includes a housing 410, the bottom surface of which is fixedly connected to the top surface of the base 300. A filter screen 420 is rotatably connected inside the housing 410. The outer wall of the filter screen 420 is rotatably connected to the inner wall of the rotating ring 215. A sleeve 421 is fixedly connected to one side wall of the filter screen 420. A conveying shaft 430 is rotatably connected to the inner wall of the sleeve 421. Spiral blades 431 are fixedly connected to the outer wall of the conveying shaft 430 located inside the filter screen 420. A motor 433 is fixedly connected to the top surface of the base 300. The motor shaft of 433 is driven by a rotating shaft 434. The other end of the rotating shaft 434 is rotatably connected to the outer wall of the housing 410. A pulley 432 is driven between the rotating shaft 434 and the conveying shaft 430. A liquid discharge pipe 411 is provided on the bottom surface of the housing 410. A solid discharge pipe 450 is provided on the end of the housing 410 away from the screening mechanism 200. A side plate 320 is fixedly connected to the top surface of the base 300. Two hydraulic cylinders 321 are fixedly connected to the side wall of the side plate 320 near the solid discharge pipe 450. A pressure plate 322 is fixedly connected to the end of the two hydraulic cylinders 321.

[0029] In practice, the filter screen 420 has a slot that matches the bottom of the feeding pipe 213. The sludge that has been screened enters the filter screen 420 through the slot. At the same time, the motor shaft of the drive motor 433 drives the rotating shaft 434, and the conveying shaft 430 rotates under the transmission of the pulley 432. The rotating conveying shaft 430 and the spiral blades 431 transport the sludge forward. During the transportation process, the sludge is dewatered, and the liquid seeps out from the filter screen 420 and finally flows out from the liquid discharge pipe. 411 is discharged, and the remaining sludge continues to be conveyed forward until it is pushed to the end near the pressure plate 322. The continuously pushed sludge comes into contact with the pressure plate 322 and is squeezed, further dewatering. The dewatered sludge cake is squeezed out from the gap between the pressure plate 322 and the filter screen 420 and discharged from the solid discharge pipe 450, realizing solid-liquid separation. The distance between the pressure plate 322 and the port of the filter screen 420 can be adjusted by controlling the extension or contraction of the hydraulic cylinder 321, and the pressure applied to the sludge can be controlled.

[0030] Example 2

[0031] Based on Example 1, in order to facilitate cleaning the interior of the spiral dewatering machine 400.

[0032] like Figure 4As shown, in this embodiment, a gear ring 422 is fixedly fitted onto the outer wall of the sleeve 421, a motor sleeve 423 is fixedly connected to the outer wall of the housing 410, a second motor 424 is fixedly connected to the motor sleeve 423, a gear 425 is driven by the motor shaft of the second motor 424, and the gear 425 and the gear ring 422 mesh and drive each other, a spray pipe 440 is fixedly connected to the inner top surface of the housing 410, a plurality of nozzles 442 are fixedly connected at equal intervals to the bottom surface of the spray pipe 440, and a water inlet pipe 441 is inserted and fixedly connected to the top surface of the housing 410, with the bottom end of the water inlet pipe 441 communicating with the interior of the housing 410.

[0033] In practice, after the sludge dewatering is completed, the equipment needs to be cleaned. Clean water is injected into the spray pipe 440 through the water inlet pipe 441. The clean water will spray out from several nozzles 442 to rinse the outer surface of the filter screen 420. At the same time, the motor shaft of the second drive motor 424 is driven by the gear 425, so that the gear 425 and the gear ring 422 mesh and drive, so that the sleeve 421 drives the filter screen 420 to rotate, so that the clean water washes the entire outer wall of the filter screen 420 and washes off the sludge adhering to the inner wall of the filter screen 420. Then, the motor shaft of the third drive motor 433 is driven by the rotating shaft 434, so that the conveying shaft 430 and the spiral blades 431 rotate to discharge the washed-off sludge into the filter screen 420.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
