[0006] The roller assembly includes an inlet pipe, a drain pipe, several connecting plates, a screen, and several augers. The inlet pipe and the drain pipe are both mounted on the base assembly. Several connecting plates are circumferentially fixed between the inlet pipe and the drain pipe. The screen covers the outer circumferential walls of the inlet pipe and the drain pipe. Several augers are circumferentially fixed between the inner circumferential walls of the inlet pipe and the drain pipe. The clamping assembly includes several rotating rods and several clamping blocks. Several rotating rods are circumferentially rotatably mounted on the outer circumferential walls of the inlet pipe and the drain pipe. The clamping blocks are fixedly mounted on one end of the rotating rods.

[0007] Furthermore, the base assembly includes a frame, two rotating shafts, four rollers, and a motor. The two rotating shafts are rotatably mounted on the top of the frame, and the four rollers are respectively fixedly mounted on the outer circumference of the two rotating shafts. The water inlet pipe is rotatably mounted between two of the rollers, and the sewage pipe is rotatably mounted between the other two rollers. The motor is fixedly mounted on one side of the frame, and one of the rotating shafts is connected to the output shaft of the motor via a chain.

[0008] Furthermore, the clamping assembly also includes several fixing plates, which are circumferentially and equidistantly fixed on the outer circumferential walls of the water inlet pipe and the sewage outlet pipe, and the rotating rod is rotatably installed between two fixing plates.

[0009] Furthermore, the clamping assembly also includes a sliding ring, a movable ring, several arc-shaped plates, several slide bars, several racks, several limiting rods, and ball bearings. Two sliding rings are slidably fitted onto the outer circumference of the inlet pipe and the drain pipe, respectively. Two movable rings are slidably fitted onto the outer circumference of the inlet pipe and the drain pipe, respectively. The sliding rings are in contact with the movable rings. Several arc-shaped plates are equidistantly fixedly installed on the outer circumference of the sliding ring. Slide bars are fixedly installed on the inner arc-shaped walls of the arc-shaped plates. The outer wall of the movable ring has an annular groove, and the slide bars are slidably installed in the annular groove. Several racks are equidistantly fixedly installed at one end of the sliding ring. Limiting rods are fixedly installed at one end of the racks. Several gear blocks are provided on the outer circumference of the rotating rod. The gear blocks mesh with the racks. Ball bearings are rotatably installed on the inner circumference of the movable ring. Arc-shaped grooves are provided on the outer circumference of both the inlet pipe and the drain pipe, and ball bearings are slidably installed in the arc-shaped grooves.

[0010] Furthermore, two toothed blocks are fixedly installed on the clamping block, and toothed grooves are opened on the outer circumference of the water inlet pipe and the sewage outlet pipe, and the toothed blocks are adapted to the toothed grooves.

[0011] Furthermore, the clamping assembly also includes a fixed ring, a slider, a locking block, a spring, and a fixed rod.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This invention, through its clamping assembly, simplifies filter replacement by requiring only the insertion and pressing of an Allen wrench into the hexagonal slot. Guided by the ball bearings and the arc-shaped groove, the movable ring rotates while simultaneously pushing the sliding ring, which in turn drives the rack to rotate the rotating rod and clamping block, disengaging the clamping block from the filter. A positioning pin then temporarily secures the new filter to the roller assembly. Pressing the Allen wrench again causes the movable ring to rotate while pulling the sliding ring, which in turn pulls the rack to rotate the rotating rod and clamping block, bringing the clamping block into contact with the filter. Finally, a locking block secures the movable ring, thus locking the clamping block and completing the filter replacement. This eliminates the need for disassembling numerous bolts, simplifying the replacement process. Attached Figure Description

[0028] Figures 1-10 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Appendix Figure 10 The present invention will be further described below.

[0029] An industrial wastewater treatment device includes a base assembly 1 and a roller assembly 2, and also includes two clamping assemblies 3. The roller assembly 2 is disposed on the base assembly 1, and the two clamping assemblies 3 are symmetrically disposed on the roller assembly 2.

[0030] The roller assembly 2 includes an inlet pipe 201, a drain pipe 202, several connecting plates 203, a screen, and several augers 204. The inlet pipe 201 and the drain pipe 202 are both mounted on the base assembly 1. Several connecting plates 203 are circumferentially fixed between the inlet pipe 201 and the drain pipe 202. The screen covers the outer circumferential walls of the inlet pipe 201 and the drain pipe 202. Several augers 204 are circumferentially fixed between the inner circumferential walls of the inlet pipe 201 and the drain pipe 202. The clamping assembly 3 includes several rotating rods 302 and several clamping blocks 303. Several rotating rods 302 are circumferentially rotatably mounted on the outer circumferential walls of the inlet pipe 201 and the drain pipe 202. The clamping blocks 303 are fixedly mounted on one end of the rotating rods 302.

[0031] Specifically, the base assembly 1 includes a frame 101, two rotating shafts 102, four rollers 103, and a motor. The two rotating shafts 102 are rotatably mounted on the top of the frame 101. The four rollers 103 are respectively fixedly mounted on the outer circumference of the two rotating shafts 102. The water inlet pipe 201 is rotatably mounted between two of the rollers 103, and the sewage pipe 202 is rotatably mounted between the other two rollers 103.

[0032] Specifically, the clamping assembly 3 also includes several fixing plates 301, which are circumferentially fixedly installed on the outer circumference of the water inlet pipe 201 and the sewage pipe 202, respectively, and the rotating rod 302 is rotatably installed between two fixing plates 301.

[0033] Specifically, the clamping assembly 3 also includes a sliding ring 306, a movable ring 307, several arc-shaped plates 311, several slide bars 312, several racks 313, several limiting rods 314, and ball bearings 315. Two sliding rings 306 are slidably fitted onto the outer circumference of the inlet pipe 201 and the drain pipe 202, respectively. Two movable rings 307 are slidably fitted onto the outer circumference of the inlet pipe 201 and the drain pipe 202, respectively. The sliding rings 306 and movable rings 307 are in contact. Several arc-shaped plates 311 are equidistantly fixedly installed on the outer circumference of the sliding rings 306. Slide bars 312 are fixedly installed on the arc-shaped plates 311. The inner wall of the movable ring 307 has an arc-shaped groove 308 on its outer wall. The slide bar 312 is slidably installed in the annular groove 308. Several racks 313 are equidistantly fixed at one end of the sliding ring 306. The limiting rod 314 is fixedly installed at one end of the rack 313. Several gear blocks 304 are provided on the outer wall of the rotating rod 302. The gear blocks 304 mesh with the racks 313. The ball bearings 315 are rotatably installed on the inner wall of the movable ring 307. The outer walls of the water inlet pipe 201 and the sewage pipe 202 are both provided with arc-shaped grooves 207. The ball bearings 315 are slidably installed in the arc-shaped grooves 207.

[0034] Specifically, two toothed blocks 305 are fixedly installed on the clamping block 303. The outer circumferential walls of the water inlet pipe 201 and the sewage pipe 202 are provided with toothed grooves 205, and the toothed blocks 305 are adapted to the toothed grooves 205.

[0035] In this embodiment, by setting toothed blocks 305 and toothed grooves 205, when the clamping block 303 clamps the filter screen, the toothed blocks 305 can press the filter screen into the toothed grooves 205, thereby improving the stability of clamping.

[0036] Specifically, the clamping assembly 3 also includes a fixing ring 206, a slider 209, a locking block 210, a spring 211, and a fixing rod 212. The two fixing rings 206 are respectively fixedly installed on the outer circumference of the water inlet pipe 201 and the sewage pipe 202. A vertical groove 208 is provided at one end of the fixing ring 206. The slider 209 is slidably installed in the vertical groove 208. The locking block 210 is fixedly installed at one end of the slider 209. The spring 211 is fixedly installed between the top of the slider 209 and the top inner wall of the vertical groove 208. The fixing rod 212 is fixedly installed in the vertical groove 208. The slider 209 is slidably sleeved on the outer circumference of the fixing rod 212. A locking groove 310 is provided on the outer circumference of the movable ring 307. The locking block 210 is adapted to the locking groove 310.

[0037] Specifically, the outer circumference of the movable ring 307 is provided with several hexagonal grooves 309 at equal intervals.

[0038] In this embodiment, the hexagonal groove 309 allows workers to use an Allen wrench to rotate the movable ring 307.

[0039] Specifically, several positioning pins 4 are fixedly installed at equal intervals on one of the connecting plates 203.

[0040] In this embodiment, the positioning pin 4 can temporarily fix the filter screen when installing a new filter screen.

[0041] Working principle: When the filter needs to be replaced, first slide the locking block 210 to disengage it from the locking slot 310, which unlocks the movable ring 307. The sliding block 210 will cause the slider 209 to slide in the vertical groove 208 and compress the spring 211. Then, insert the Allen wrench into the hexagonal groove 309 and press the Allen wrench to rotate the movable ring 307. When the movable ring 307 rotates, it will cause the ball bearing 315 to slide in the arc-shaped sliding groove 207. At this time, the ball bearing 315 will be guided by the arc-shaped sliding groove 207 and will cause the movable ring 307 to rotate while pushing the sliding ring 306 to slide. The sliding ring 306 will push the rack 313 to slide. The sliding rack 313 will drive the rotating rod 302 to rotate through the gear block 304. The rotation of the rotating rod 302 will cause the clamping block 303 to move away from the filter. After the clamping block 303 is disengaged from the filter, the filter can be removed. Then, one end of the new filter can be hung on the positioning pin 4. After circling the roller assembly 2 once, hang the other end of the new filter screen on the positioning pin 4 to temporarily fix the filter screen. At this time, lift the Allen wrench upward to rotate the movable ring 307. Under the guidance of the arc-shaped slide groove 207, the movable ring 307 rotates and drives the slide bar 312 and the arc plate 311 to slide. The sliding of the arc plate 311 will pull the sliding ring 306 to slide. At this time, the sliding ring 306 will pull the rack 313 to slide. The sliding of the rack 313 will drive the rotating rod 302 to rotate through the gear block 304. At this time, the rotation of the rotating rod 302 will drive the clamping block 303 to approach the filter screen. When the clamping block 303 is completely in contact with the filter screen, the slot 310 on the movable ring 307 will rotate to correspond to the clamping block 210. At this time, the clamping block 210 will re-engage into the slot 310 under the push of the spring 211, thereby locking the movable ring 307 and several clamping blocks 303, thus completing the filter screen replacement.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
