a through hole 9 is formed in the middle of an upper side plate 411 of the water tank 6, a left sliding plate and a right sliding plate 10 are symmetrically arranged above the upper side plate 411 of the water tank 6, the sliding plates 10 can move left and right and are mutually close to reset, and the left sliding plate and the right sliding plate 10 can block the through hole 9 after being close to each other; the outer side of each sliding plate 10 is connected with a rope 11, and the other end of each rope 11 is fixed on the second supporting rod 3; after the water tank 6 descends along with the filter body 4, the rope 11 is tensioned, and the left sliding plate 10 and the right sliding plate 10 can move back to back; so that the through-hole 9 is opened.
In order to realize the installation of the filter body 4, the shell 401 of the filter body 4 on install a plurality of sleeves 12, the second support rod 3 runs through the sleeves 12, every second support rod 3 is equipped with an extension spring 13, the upper end of the extension spring 13 is fixed at the top of the bracket 1, and the lower end of the extension spring 13 is fixed on the sleeve 12.
In order to realize the installation and the reset of the sliding plate 10, a guide rail 15 is arranged on an upper side plate 411 of the water tank 6, the sliding plate 10 can move left and right along the guide rail 15, and a pressure spring 19 is connected between the outer side surface of the sliding plate 10 and the second support rod 3; a collar 20 is fixed to the upper side plate 411 of the water tank 6, and the middle part of the rope 11 runs through the collar 20 and is diverted by the collar 20.
In order to avoid the filter 4 from excessively descending, a second limiting protrusion 16 corresponding to the lower end of the rack 406 is fixed on each first supporting rod 2.
In order to more stably enable the rotating shaft 404 to support the cylinder 407, a plurality of wales 17 are fixed on the rotating shaft 404, and the end portions of the wales 17 are fixed on the inner side surface of the cylinder 407.
In order to enable the water baffle 409 hinged at the opening 408 to reset after rotating, the upper end of the water baffle 409 is hinged with the upper side surface of the opening 408, a torsion spring is installed at the hinged point, and the torsion spring can enable the water baffle 409 to be kept in a state of blocking the opening 408.
In order to facilitate the discharge of the impurities to both sides, a chute 18 is fixed on each first supporting rod 2 and is arranged obliquely.
In order to enhance the filtering effect, the bottom of the casing 401 is inclined with a lower middle and two higher sides, and the bottom of the casing 401 is in a filter mesh shape.
When the present invention is used, firstly, in the case that the filter 4 is not blocked, i.e. the lower half of the strainer 410 in the cylinder 407 is not blocked, the sewage flows downward from the upper water inlet 5, and then directly enters the interior of the filter 4 through the feed port 402 of the housing 401 of the filter 4.
Since the cylinder 407 in the interior of the filter body 4 is located at the discharge port 403 of the housing 401, the sewage is filtered by the cylinder 407; specifically, in the initial state, the strainer 410 of the cylinder 407 is located below, and the upper portion corresponding to the strainer 410 is a solid portion, so that when sewage falls onto the cylinder 407 from top to bottom, the sewage is blocked by the solid portion on the cylinder 407, is dispersed to the front and rear sides of the cylinder 407, and enters the interior of the cylinder 407 through the openings 408 on the front and rear sides of the cylinder 407 by the gathering action of the housing 401; because the opening 408 is hinged with the water baffle 409, the sewage drives sundries to push the water baffle 409 to incline and enter the cylinder 407. Then, the impurities remain inside the cylinder 407 by the filter screen 410 at the bottom of the cylinder 407, and the filtered sewage flows downward through the cylinder 407.
When the filtered sewage flows downwards, the sewage on the left side and the sewage on the right side flow through the water tank 6. In the initial state, the impurities inside the cylinder 407 are less, and the filter screen 410 is not blocked, so the whole filter body 4 is at the top of the stroke, at this time, referring to fig. 2, since the state of the sliding plate 10 on the water tank 6 is closely related to the descending height of the filter body 4, when the filter body 4 is not descended, the ropes 11 at the left and right sides are in a loose state, the sliding plates 10 are pressed together by the compression spring 19, and the through hole 9 above the water tank 6 is blocked; i.e., the water flow will be blocked by the slide 10 and not enter the interior of the box.
The above is a normal filtration state; when the filter screen 410 is clogged or the filter screen 410 has heavy impurities, the downward component force applied to the entire filter 4 increases, the tension spring 13 of the second support rod 3 is also stretched, i.e., the filter 4 descends, and when the filter 4 descends, the water tank 6 descends. When the water tank 6 descends, the rope 11 is tightened, and the sliding plate 10 is pulled to move towards two sides at the moment, so that the through hole 9 above the water tank 6 is partially opened, the sliding plate 10 does not completely block sewage any more, and a part of sewage can enter the water tank 6; thereby increasing the weight of the water tank 6.
As the weight of the water tank 6 is increased, the whole filter body 4 and the water tank 6 are further lowered, so that a positive feedback phenomenon occurs, that is, the more water is introduced into the water tank 6, the more the water tank 6 is lowered, the more the through hole 9 is opened, and the more water is introduced into the water tank 6. With the continuous descending of the filter body 4, the gear 405 at the end of the rotating shaft 404 penetrating through the filter body 4 is meshed with the rack 406 on the first support rod 2, and because the weight of the water in the water tank 6 is larger, the water is pulled by the gravity of the water tank 6; the gear 405 drives the rotating shaft 404 to rotate; then the rotating shaft 404 drives the cylinder 407 to rotate; due to the length limitation of the rack 406, the rotating shaft 404 can only drive the cylinder 407 to rotate 180 degrees, i.e. the cylinder 407 is upside down. See fig. 4 and 5; the lower screen 410 would be at the top at this time; and the inner impurities fall into the solid part of the cylinder 407; and the sundries can not fall out in the overturning process due to the action of the water baffle 409. As sewage is still entering; at this time, the sewage reversely flushes the filter screen 410, enters the cylinder 407 after being filtered by the filter screen 410, and flushes the impurities on the solid part; because the side plate 411 is provided with the slag discharge port 412, the slag discharge port 412 is also positioned at the lower position after the side plate is turned over, so that impurities can be discharged from the slag discharge ports 412 at two sides; and the impurities fall on the slideway 18 and are discharged to both sides. The discharged sundries can be collected and treated uniformly by the collecting box.
During the above-mentioned overturning, the water in the tank 6 is already close to the discharge level of the siphon 7; after the sundries are discharged for a certain time, the water filtered and discharged through the gaps of the discharge holes 403 of the shell 401 and the cylinder 407 and the inclined filter screen 410 at the bottom of the shell 401 can continuously enter the water tank 6, so that the water in the water tank 6 reaches the drainage height; at this time, the water in the water tank 6 is discharged completely as soon as it is discharged; the weight of the water tank 6 is then reduced; the entire apparatus is raised, and the drum 407 is rotated in reverse and reset to its original state.
The device uses the descending generated after the filter body 4 is blocked or the load is too large as an automatic judgment condition, thereby using the descending height; after the sliding plate 10 moves, a large amount of water flows into the water tank 6, and then the weight of the water tank 6 is utilized to achieve the purpose of pulling the whole filter body 4 to descend greatly again, so that the cylinder 407 is overturned, sundries are discharged, and the filter screen 410 is cleaned; simple, efficient and automatic. Because the blocking condition and the loading condition of the filter screen 410 are utilized, when the sewage is relatively clean, the whole device cannot be cleaned frequently, and the overall stability is improved.
Ingenious design drum 407's structure in this device, make drum 407's initial state can filter through filter screen 410, can fall on drum 407's solid face through debris after the upset to continue to utilize the scouring action of sewage, make debris discharge from both sides, collect, avoid mixing with the sewage that filters, can also play the effect of reverse flush filter screen 410 simultaneously, avoided filter screen 410 because of the jam that little debris produced.
This device is arranging the sediment after, a period of time after, and the water in the water tank 6 can discharge fast, has realized the automation of whole device and has reset, must artificial intervention, has alleviateed the burden, has improved the life of device, has avoided long-time jam of filter screen 410 or long-time high load.
