Description

Technical Field

[0001] This utility model relates to a filter basket cleaning device, belonging to the field of filter basket cleaning technology. Background Technology

[0002] Cylindrical filter baskets are commonly used pre-pump filters in polyester spinning processes, primarily for filtering ethylene glycol (which has properties similar to alcohol), a key raw material for polyester. Because a small amount of muddy, grayish-white, slightly sticky residue is present in the ethylene glycol during production, a pre-pump filter using a cylindrical filter basket is installed for filtration. Therefore, filter basket cleaning is a crucial aspect of polyester production, and its efficiency and quality directly impact the stability of polyester production.

[0003] Chinese utility model patent CN215427771U discloses a cylindrical filter basket cleaning device, including a frame with a cleaning tank mounted on it. A sealing door is hinged to one side of the cleaning tank. A rotating shaft is rotatably mounted on the frame, with one end connected to a second motor for power adjustment and the other end equipped with a chuck to fix the filter basket. A spray pipe is slidably connected to the frame via a linear motion bearing. An inner spray pipe and an outer spray pipe are connected in parallel at the outlet end of the spray pipe, and both the inner and outer spray pipes are equipped with high-pressure spray heads. In use, the filter basket is fixed by the chuck, the second motor rotates the filter basket, and the operator pushes the spray pipes towards the bottom of the filter basket. The high-pressure spray heads remove impurities from the surface of the filter basket, achieving rapid cleaning. Compared with existing technologies, this device not only effectively recovers wastewater and prevents environmental pollution caused by cleaning, but also has high cleaning efficiency and effectively reduces the labor intensity of operators.

Detailed Implementation

[0027] like Figure 1-5 As shown, a filter basket cleaning device in this embodiment includes a cleaning tank 100. The cleaning tank 100 is provided with a spraying mechanism 200 and a rotating mechanism 300. The rotating mechanism 300 is used to drive the filter basket 500 to rotate, and the spraying mechanism 200 is used to apply water to the filter basket 500.

[0028] The spraying mechanism 200 includes a support 201, a first nozzle 202, and two second nozzles 203. The support 201 is fixedly mounted on the cleaning tank 100, and the first nozzle 202 is fixedly mounted on the support 201, located above the rotating mechanism 300. The two second nozzles 203 are respectively located on both sides of the rotating mechanism 300, and both second nozzles 203 are driven to rise and fall by a moving module. The first nozzle 202 and the two second nozzles 203 are all connected to a water source. During cleaning, the filter basket 500 is inverted and fixedly mounted on the rotating mechanism 300. In fact, the filter basket 500 is cylindrical. The filter basket 500 is vertically arranged. The filter basket 500 is driven to rotate by a rotation drive. Water is delivered to the first nozzle 202 and the second nozzle 203 through a water source and then discharged. The water discharged from the first nozzle 202 acts on the top of the filter basket 500, and the water discharged from the second nozzle 203 acts on the outer peripheral wall of the filter basket 500. Through the rotation of the filter basket 500, the water discharged from the second nozzle 203 is evenly applied to the outer periphery of the filter basket 500. At the same time, the second nozzle 203 is driven to rise and fall by a moving module, so that the water discharged from the second nozzle 203 is evenly distributed along the axial direction of the filter basket 500. In this way, under the action of water flow, the impurities on the filter basket 500 are washed off.

[0029] The moving module includes a lead screw 204, which is arranged vertically. A slider 205 is threaded onto the lead screw 204. The lead screw 204 is driven by a first motor 206. A second nozzle 203 is disposed on the slider 205. When the first motor 206 is started, the lead screw 204 is rotated, thereby causing the slider 205 to rise and fall on the lead screw 204. The rising and falling of the slider 205 drives the second nozzle 203 to rise and fall.

[0030] The rotating mechanism 300 includes a rotating disk 301, a fixed rod 302, and scrapers 303. Both the fixed rod 302 and the scrapers 303 are vertically arranged. Each scraper 303 is fixed to one side of the fixed rod 302 via multiple connecting members distributed from top to bottom. Multiple scrapers 303 are evenly distributed circumferentially around the fixed rod 302. The rotating disk 301 is coaxially sleeved on the fixed rod 302 and rotatably connected to it. The rotating disk 301 is located below the scrapers 303. A driving system is connected to the rotating disk 301, driving it to rotate. Multiple clamping systems are provided on the rotating disk 301 to fix it in place. The rods 302 are evenly distributed around the center. The clamping system consists of three rods. During cleaning, the filter basket 500 is placed upside down on top of the rotating disk 301, and the scraper rods 303 abut against the inner peripheral wall of the filter basket 500. The clamping system fixes the filter basket 500 to the rotating disk 301. Then, the rotating disk 301 is rotated by the drive system. The rotation of the rotating disk 301 drives the filter basket 500 to rotate. When water is applied to the filter basket 500, the debris on the filter basket 500 is concentrated on the inner peripheral wall of the filter basket 500. At this time, since the scraper rods 303 are stationary, the rotation of the filter basket 500 can scrape off the debris on the inner peripheral wall of the filter basket 500, thereby avoiding the residue of debris on the filter basket 500 and improving the cleaning effect of the filter basket 500.

[0031] The connector includes a connecting rod 304 and a sleeve 305. The connecting rod 304 is horizontally arranged and perpendicular to and intersects the axis of the fixed rod 302. The sleeve 305 is coaxially arranged with the connecting rod 304. The connecting rod 304 and the sleeve 305 are located between the scraper rod 303 and the fixed rod 302. One end of the sleeve 305 is fixedly mounted on the fixed rod 302. One end of the connecting rod 304 is movably inserted into the other end of the sleeve 305. The other end of the connecting rod 304 is fixedly mounted on the scraper rod 303. The connecting rod 304 and the sleeve 305 are locked together by a locking device, namely a screw 306. When the inner diameter of the filter basket 500 changes, the screw 306 is loosened, allowing the connecting rod 304 to move on the sleeve 305, so that the scraper rod 303 can adjust its position according to the inner diameter of the filter basket 500. After adjustment, the screw 306 is tightened.

[0032] The drive system includes a rotating tube 307, which is coaxially sleeved on a fixed rod 302. The rotating tube 307 is rotatably connected to the fixed rod 302 via a first bearing 308. The rotating tube 307 is fixedly passed through a rotating disk 301. A driven gear 309 is mounted on the outer peripheral wall of the rotating tube 307, located below the rotating disk 301. A drive shaft 310 is provided on one side of the fixed tube, and the drive shaft 310 is rotatably connected to the cleaning tank 100 via a second bearing 311. A driven wheel 312 and a drive gear 313 are mounted on the drive shaft 310, and the drive gear 313 meshes with the driven gear 309. The cleaning tank 100 is equipped with a second motor 314, and a drive wheel 315 is mounted on the second motor 314. The drive wheel 315 is connected to the driven wheel 312 through a transmission belt 316. When the second motor 314 starts, it drives the drive wheel 315 to rotate. The rotation of the drive wheel 315 drives the driven wheel 312 to rotate through the transmission belt 316, thereby causing the drive shaft 310 to rotate on the second bearing 311. The rotation of the drive shaft 310 drives the drive gear 313 to rotate, and the rotation of the drive gear 313 drives the driven wheel 312 to rotate, thereby causing the rotating tube 307 to rotate on the first bearing 308. The rotation of the rotating tube 307 drives the rotating disk 301 to rotate synchronously.

[0033] The clamping system includes a clamping block 317, a moving rod 318, and a fixing block 319. The fixing block 319 is fixedly mounted on the rotating disk 301. The moving rod 318 movably passes through the fixing block 319 and is horizontally arranged. The axis of the moving rod 318 is perpendicular to and intersects the circumferential direction of the fixing rod 302. The clamping block 317 is fixedly mounted on the side of the moving rod 318 closest to the fixing rod 302. The moving rod 318 is connected to the fixing block 319 by a spring 320. A chamfer is provided on the side of the top of block 319 near the fixed rod 302. When the filter basket 500 is placed vertically on the top of the rotating disk 301, the filter basket 500 is placed from top to bottom, causing the filter basket 500 to push the clamping block 317 to move away from the fixed rod 302. The movement of the clamping block 317 drives the moving rod 318 to move synchronously, and causes the spring 320 to deform. Through the elastic force of the spring 320, the clamping block 317 generates a clamping force on the filter basket 500, thus achieving the clamping and fixing of the filter basket 500.

[0034] The rotating disk 301 is provided with a through hole 321, and the bottom of the cleaning tank 100 is provided with a drain pipe 400. The water generated by the cleaning filter basket 500 carries the debris and flows from the through hole 321 to the bottom of the cleaning tank 100 and is discharged from the drain pipe 400.

[0035] In summary, when cleaning the filter basket 500, the scraper 303 scrapes off the debris on the inner wall of the filter basket 500, thereby avoiding the residue of debris on the filter basket 500 and improving the cleaning effect of the filter basket 500.

[0036] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
