The emergence of a large number of urban sewage treatment plants has effectively relieved the pressure on the urban water environment, but it has also brought The problem of how to deal with sludge in sewage treatment plants. Sludge is composed of bacterial micelles, organic matter, heavy metals, salts, and parasite eggs formed by various microorganisms. If it is not handled properly, it will easily cause secondary pollution, and it will inevitably bring worse results to people's living environment. Therefore, how to effectively treat sludge in urban sewage treatment is one of the most important research objects.

During the treatment of urbanization sludge, since the sludge contains impurities such as metals, wood, stones, plastics, etc., these impurities need to be filtered out of the sludge before entering the sludge treatment system, otherwise it will lead to The sludge pipeline is blocked, and it is easy to cause damage to the equipment used to transport the sludge, such as the screw rod and the feeding pump. Therefore, the impurity filtration work before the sludge treatment is extremely important, but the existing sludge impurity filtration equipment is still There are following deficiencies:

1. The design of the equipment structure is complicated, and multiple devices are required to cooperate to complete the sludge impurity filtration work. The entire sludge impurity filtration process is cumbersome, and the device is large in size, making maintenance and repair work difficult;

2. Filtering of sludge impurities requires the use of filter screens, grille plates and other devices, but the structural position of the filter screen or grille plates inside the existing equipment is defective, and the filter screen or grille plates are directly installed horizontally on the equipment Internally, the impurities carried by the sludge directly impact the filter screen or grille, and then rely on gravity to separate the impurities from the sludge, but cause a certain degree of damage to the filter screen or grille, which not only reduces the Or the service life of the grid plate, and it is easy to cause damage to the filter screen or grid plate, resulting in impurities and sludge being discharged from the equipment together;

3. After clogging occurs during the sludge filtration process, it is necessary to manually open the equipment for cleaning. The method of cleaning the clogging is inefficient, and disassembling the equipment affects the normal operation of the equipment and delays the sludge filtration work;

4. After the sludge filtration is completed, it is inconvenient to discharge the sludge, and it is easy to disperse and accumulate inside the equipment without being concentrated together. It needs to be washed with the help of water, resulting in waste of resources.

1) sludge is added, sludge is added to the inside of charging frame (4), the sludge of soft state is in the interior of charging frame (4) at this time Portion's sliding drops on right buffer board (5), then falls from right buffer board (5) on left buffer board (6), finally by left buffering Plate (6) is fallen into the filter chamber (8) of Rose Box (1)；

2) filter sludge falls into the sludge in Rose Box (1) and is fallen on the second flase floor (103) first, and then sludge relies on Gravity slides on the second flase floor (103) being obliquely installed, and sludge is fallen by the second flase floor (103) while landing On blanking partition (7), the bulks impurity such as the stone in sludge, metal is blocked at this time, and then sludge is in the second flase floor (103) it slides on on the first flase floor (102), then sludge is fallen by the first flase floor (102) in blanking partition (7) On, while impurity being deposited on the first flase floor (102) under sludge drive and under automatic gravity；

3) sludge is discharged, sludge is fallen on blanking partition (7) under the effect of gravity along under the inclined direction of blanking partition (7) It falls, is finally deposited in the least significant end of blanking partition (7), draw the cooperations of material frame (12) by two at this time, by sludge toward sewage pipe (13) position is accumulated, and then sewage pipe (13) connection is used for the device of sucking sludge, opened on sewage pipe (13) Rose Box (1) is discharged in sludge by valve；

4) impurity is cleared up, it can be by opening impurity in observation window (3) observation the second flase floor (103) on sealing frame (2) Then accumulation situation is dismantled the bolt for clearing up window (15) by tools such as spanners, will be after cleaning window (15) removes, by the Impurity on two flase floors (103) is cleared up, and then cleaning window (15) is fixed using bolt with Rose Box (1) again；

5) blocking is rinsed, when the impurity in sludge excessively causes the first flase floor (102) or the second flase floor (103) to block When, sludge is deposited on filter assemblies (10) and can not be discharged at this time, starts booster water pump (112) at this time, and booster water pump (112) is opened The internal water of water storage cavity (9) is extracted in beginning work out, by entering isocon (116) after water inlet pipe (113) and water-supply-pipe (114) Inside, the second flase floor (103) is rinsed then into spray head (115), by by sludge dilute and by water flow Filter assemblies (10) are carried out blocking cleaning by the effect of impulse force.
