Description

Technical Field

[0001] The utility model relates to the technical field of sludge dehydration, in particular to a self-cleaning squeezing and dehydrating integrated machine. Background Art

[0002] Sludge dehydration is a sludge treatment method that removes water from flowing primary, concentrated or digested sludge and converts it into semi-solid or solid mud blocks. The main dehydration methods include natural drying, mechanical dehydration and granulation.

[0003] According to the patent announcement number CN 220633273 U, a screw conveying and pressing integrated machine for deep dehydration of sludge is disclosed. The device can squeeze out water from the conveyed sludge through a pressing roller by installing a sludge pressing device, and the pressing roller squeezes the sludge back and forth for multiple times, and can fully squeeze out the water in the sludge before stopping, thereby improving the efficiency of subsequent sludge drying. A sludge screw conveying device is installed, and the sludge is conveyed to the pressing device along the spiral blades through feeding, saving the time of transporting the sludge to the pressing device alone, and the water filter holes provided at the bottom of the box body can filter out part of the water during transportation, thereby reducing multiple pressing of the pressing roller; however, the device cannot self-clean the filter plate, and when cleaning the filter plate, it needs to be cleaned manually, thereby wasting manpower and affecting the subsequent use of the device.

[0026] Example 1

[0027] like Figure 1-5 As shown, the utility model provides a technical solution: a self-cleaning squeezing and dehydrating integrated machine, comprising a workbench 1, a water tank 2 fixedly mounted at the bottom of the workbench 1, a water outlet pipe 4 connected to the right side of the water tank 2, and a connecting assembly 3 arranged at the top of the workbench 1, the connecting assembly 3 comprising a dehydrating mechanism 31 arranged at the top of the workbench 1, a filtering mechanism 32 arranged at the bottom of the workbench 1, a through hole arranged inside the workbench 1, a valve arranged at one side of the water outlet pipe 4, the dehydrating mechanism 31 comprising a motor 311 fixedly mounted on the left side of the workbench 1 through a base, a screw rod 312 fixedly connected to the output end of the motor 311, a first slide groove 313 opened at the top of the workbench 1, and a mounting frame 314 slidably connected to the inner wall of the first slide groove 313 A first telescopic rod 315 is fixedly installed on the upper part of the mounting frame 314, and a mounting seat 316 is fixedly connected to the output end of the first telescopic rod 315, and a pressing roller 317 is rotatably connected inside the mounting seat 316. A first filter plate 318 is fixedly installed on the upper part of the workbench 1, and a second slide groove 319 is opened on the upper part of the workbench 1, and a slide rod 3110 is fixedly connected to the inner wall of the second slide groove 319. A connecting plate 3111 is fixedly connected to one side of the mounting frame 314, and a second telescopic rod 3112 is fixedly installed on the upper part of the connecting plate 3111, and a mounting plate 3113 is fixedly connected to the output end of the second telescopic rod 3112, a scraper 3114 is fixedly connected to the lower part of the mounting plate 3113, and a cleaning brush 3115 is fixedly connected to the lower part of the mounting plate 3113.

[0028] In this embodiment, the screw rod 312 is rotatably connected to the workbench 1 through a bearing, the mounting frame 314 is threadedly connected to the outer wall of the screw rod 312, the output end of the first telescopic rod 315 is movably connected to the upper part of the mounting frame 314, and the mounting frame 314 is slidably connected to the outer wall of the sliding rod 3110. Through the cooperation of the screw rod 312, the mounting frame 314, the first telescopic rod 315, the mounting seat 316, and the pressure roller 317, the sludge can be squeezed back and forth to dehydrate, thereby achieving a better dehydration effect on the sludge.

[0029] Furthermore, the output end of the second telescopic rod 3112 is movably connected to the connecting plate 3111.

[0030] When the device is in use, the sludge is first manually transported to the upper part of the first filter plate 318, and then the first telescopic rod 315 is manually controlled to drive the mounting seat 316 to move downward, so that the pressing roller 317 can move downward. When the pressing roller 317 moves downward to a suitable position, the motor 311 is manually started to drive the screw rod 312 to reciprocate in positive and negative directions, so that the mounting frame 314 threadedly connected to the outer wall of the screw rod 312 can reciprocate left and right on the upper part of the workbench 1, so that the pressing roller 317 can squeeze and dehydrate the sludge, and the separated water will pass through the first The filter plate 318 then falls into the water tank 2 through the through hole. Further, when the first filter plate 318 needs to be cleaned, it is only necessary to manually control the first telescopic rod 315 to move the pressing roller 317 away from the first filter plate 318, and control the second telescopic rod 3112 to drive the mounting plate 3113 to move downward. When it moves to a suitable position, the motor 311 is manually started to make the mounting plate 3113 move back and forth left and right on the upper part of the workbench 1.

[0032] On the basis of Example 1, a preferred embodiment of a self-cleaning squeezing and dehydrating integrated machine provided by the utility model is as follows Figures 1 to 5As shown: the filtering mechanism 32 includes a second filtering plate 321 movably connected to the inside of the water tank 2, a sealing ring 322 is fixedly connected to the inner wall of the water tank 2, a snap-in groove 323 is provided on the outside of the water tank 2, a rotating rod 324 is rotatably connected to the outside of the water tank 2 through a bearing, a snap-in rod 325 is movably connected to one end of the rotating rod 324, the outer end of the snap-in rod 325 is fixedly connected to a limiting block 326, and a spring 327 is fixedly connected to the inner side of the limiting block 326.

[0033] In this embodiment, the clamping rod 325 is adapted to the clamping groove 323, and the inner end of the spring 327 is fixedly connected to the rotating rod 324. Through the cooperation of the second filter plate 321, the sealing ring 322, and the water tank 2, the detached sewage can be filtered, so that the sewage can be recycled, thereby increasing the applicability of the device. At the same time, through the cooperation of the rotating rod 324, the clamping rod 325, the limit block 326, the spring 327, and the clamping groove 323, it is convenient to manually disassemble the second filter plate 321, thereby facilitating manual cleaning of the second filter plate 321, thereby preventing the filter holes of the second filter plate 321 from being blocked.

[0034] Furthermore, there are two sealing rings 322, which are symmetrically distributed on both sides of the second filter plate 321. The sealing ring 322 is set in the gap between the water tank 2 and the second filter plate 321. By setting the sealing ring 322, sewage can be prevented from flowing into the gap between the water tank 2 and the second filter plate 321, thereby affecting the filtering effect of the device on sewage.

[0035] When sewage falls into the water tank 2 through the through hole, the sewage will be filtered by the second filter plate 321 and then collected in the water tank 2. When the second filter plate 321 needs to be disassembled, it is only necessary to manually pull the clamping rod 325 outward to separate the clamping rod 325 from the clamping groove 323, and then manually rotate the rotating rod 324 to separate the inner side of the rotating rod 324 from the outer side of the second filter plate 321. Then, the second filter plate 321 can be manually taken out, so as to facilitate manual cleaning of the second filter plate 321 and prevent the filter holes of the second filter plate 321 from being blocked.
