Description

Technical Field

[0001] The utility model relates to the technical field of papermaking wastewater treatment equipment, in particular to a desludging device for papermaking wastewater which is convenient for collection. Background Art

[0002] Papermaking is an important invention of the working people in ancient China. It is divided into two forms: machine-made and hand-made. The machine-made process is carried out continuously on a papermaking machine. The pulp suitable for paper quality is diluted with water to a certain concentration, and initially dehydrated on the wire section of the papermaking machine to form wet paper sheets. The wet paper sheets are then pressed and dehydrated, and then dried into paper. The hand-made process uses a frame with a bamboo curtain, polyester mesh or copper mesh to copy the fibers dispersed and suspended in the water into wet paper sheets, which are pressed and dehydrated, and then dried in the sun or in an oven to form paper.

[0003] In the existing wastewater treatment desludging process, since the equipment lacks a device for collecting sludge, sludge is easily accumulated on the surface of the filter plate, causing channel blockage, reducing the desludging efficiency and failing to meet social needs. Therefore, a desludging device for papermaking wastewater that is easy to collect is proposed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 In this embodiment, a desludging device for papermaking wastewater that is convenient for collection includes a box body 1, a support frame 2 is provided on the surface of the box body 1, a water inlet pipe 3 is provided on the top of the box body 1, a guide block 4 is fixedly installed on the inner wall of the box body 1, a working mechanism 5 is provided inside the box body 1, and a feed pipe 6 is provided on the surface of the box body 1;

[0020] The working mechanism 5 includes an installation cavity 501. The installation cavity 501 is arranged at the center of the guide block 4. A desilting plate 502 is arranged inside the installation cavity 501. Since the interior of the desilting plate 502 is a mesh structure, when sewage flows into the desilting plate 502, the fine oil droplets in the sewage will condense into large oil droplets through mesh collision, which is convenient for subsequent water-oil separation treatment. A sealing ring 503 is arranged on the surface of the desilting plate 502. The sealing ring 503 made of rubber has a certain plasticity, which can compensate for the gap between the desilting plate 502 and the installation cavity 501 to avoid the gap after the desilting plate 502 rotates and cause sludge leakage. A filter plate 504 is arranged on the top of the desilting plate 502. A motor 505 is fixedly installed inside the guide block 4. A limiting block 506 is fixedly installed at the bottom of the guide block 4. A load-bearing rod 507 is fixedly installed on the inner wall of the box body 1. A desilting box 508 is slidably installed on the surface of the load-bearing rod 507. A motor 2 509 is fixedly installed on the left side of the mud box 508, and a threaded rod 510 is fixedly installed at the output end of the motor 2 509. A traveling block 511 is slidably installed on the surface of the threaded rod 510, and a guide seat 512 is fixedly installed on the top of the traveling block 511. A scraper rod 513 is slidably installed inside the guide seat 512. A double-headed scraper and a mud guide plate are arranged on the top of the scraper rod 513, so that the sludge on the surface of the filter plate 504 can be cleaned when the traveling block 511 moves back and forth, thereby improving the efficiency of mud removal. A spring 514 is wound around the surface of the scraper rod 513, and a stirring assembly 515 is arranged inside the box body 1. The device adopts a chemical separation method to realize water-oil separation in the wastewater. By adding a coagulant into the feed pipe 6 and driving the motor to drive the stirring rod to rotate, rapid mixing of the sewage and the coagulant can be achieved, and the coagulant can condense with the oil droplets into a colloid to make it float, thereby achieving oil-water separation.

[0021] When implementing, follow these steps:

[0022] 1) First push the desludging box 508 along the load-bearing rod 507 to the limit block 506;

[0023] 2) Then, the motor 1 505 is driven to flip the desludging plate 502, so that the sludge on the surface of the desludging plate 502 falls into the desludging box 508;

[0024] 3) The second motor 509 is driven again, and the travel block 511 slides on the surface of the threaded rod 510 under the spiral transmission;

[0025] 4) Finally, under the elastic squeezing of the spring 514, the scraper at the top of the scraper rod 513 cleans the sludge on the surface of the filter plate 504 to complete the collection of the sludge.

[0026] In summary, the desludging device for papermaking wastewater which is easy to collect is provided with a working mechanism 5 inside the box body 1. Since the inner diameter of the mounting cavity 501 is consistent with the diameter of the desludging plate 502, the device drives the desludging plate 502 to rotate through the motor 1 505, so that the sludge on the surface of the filter plate 504 falls into the desludging box 508, thereby collecting the sludge. The motor 2 509 drives the threaded rod 510 to rotate so that the double-headed scraper on the top of the scraper rod 513 cleans the surface of the filter plate 504, thereby reducing the sludge accumulated on the surface of the filter plate 504, thereby improving the desludging efficiency of the equipment, and solving the problem that in the existing wastewater treatment desludging process, the equipment lacks a device for collecting sludge, which easily leads to the accumulation of sludge on the surface of the filter plate, causing channel blockage and reducing the desludging work efficiency.
