Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses a mixing station drainage device.

Referring to fig. 1, the drainage device comprises a filter box 1 and a water collection tank 3 communicated with the bottom of the filter box 1, wherein the top wall of the filter box 1 is provided with a plurality of water inlets 2, and the side wall of the water collection tank 3 is provided with a water outlet 4. The filter box 1 is gradually reduced downwards along the vertical direction.

Referring to fig. 2 and 3, a plurality of filter screens 11 are obliquely fixed in the filter box 1, and three filter screens 11 are selected in the embodiment of the present application. Filter screen 11 arranges in rose box 1 along vertical direction, and the aperture of lower floor's filter screen 11 all is less than upper filter screen 11, makes filter screen 11 all filter 11 with the grit of variation in size in the sewage on to improve sewage filter effect.

Referring to fig. 1 and 2, be fixed with a plurality of receivers 12 on the outer wall of rose box 1, receivers 12 are arranged outside rose box 1 along the convergent direction of rose box 1, offer the opening 121 that communicates receiver 12 on the lateral wall of rose box 1. In the lower extreme of filter screen 11 stretched into opening 121 for filter screen 11 filterable grit rolls to receiver 12 along filter screen 11 in, reduces the grit and piles up and hinder filter screen 11 to filter sewage on filter screen 11, makes filter screen 11 to filter sewage more smoothly, in order to increase filtration efficiency.

Referring to fig. 2 and 3, a fixing plate 122 is slidably inserted through one side of the storage box 12 close to the filter box 1, a fixing groove 123 for the fixing plate 122 to be inserted into is formed in the filter box 1, and the groove wall of the fixing groove 123 is in the same inclination direction as that of the filter box. The fixing plate 122 is caught by the inclination of the notch of the fixing groove 123 so that the housing case 12 is fixed to the filter tank 1, so that the sand falls into and is stored in the housing case 12. When the storage box 12 is filled with the gravel, the storage box 12 is moved in a direction away from the filter box 1, and the fixing plate 122 is separated from the fixing groove 123, so that the storage box 12 is separated from the filter box 1, and the storage box 12 is detached.

Referring to fig. 1 and 3, a plurality of through grooves 13 are formed in the circumferential side wall of the filter box 1, and the through grooves 13 correspond to the filter screens 11 one by one and are located above the filter screens 11. The side wall of the filter box 1 is slidably connected with a telescopic plate 14 which covers the through groove 13, and the telescopic plate 14 slides along the circumferential direction of the filter screen 11.

Referring to fig. 3 and 4, the retractable plate 14 is composed of a plurality of sliding plates 141, the sliding plates 141 are sequentially slidably sleeved on adjacent sliding plates 141, so that the retractable plate 14 can extend or retract, and the sliding plates 141 are distributed in a step shape. Two opposite side walls of the through groove 13 are provided with guide grooves 15 for the sliding plate 141 to slide, and the sliding plate 141 slides in the guide grooves 15 all the time.

Referring to fig. 4, a plurality of sliding blocks 142 are fixed on the outer wall of the sliding plate 141 close to the adjacent sliding plate 141, and a sliding slot 143 for sliding the sliding block 142 is formed in the adjacent sliding plate 141. When the expansion plate 14 is stretched or compressed, the sliding plate 141 is pulled, so that the sliding plate 141 drives the sliding block 142 to slide in the sliding slot 143, the sliding plate 141 slides in or out of the adjacent sliding plate 141, the side wall of the sliding block 142 abuts against the wall of the sliding slot 143, and the expansion plate 14 is fixed in a stretched or compressed state.

Referring to fig. 2, a push rod 144 penetrates through the through slot 13 at one end of the sliding plate 141, one end of the push rod 144 extends into the filter tank 1, and the other end extends out of the sliding plate 141. A scraper 145 is fixed to one end of the push rod 144 extending into the filtering box 1, and the scraper 145 is in sliding contact with the filtering net 11. The scraper 145 is used to scrape off sand on the filter screen 11 so that the filter screen 11 filters the sewage.

Referring to fig. 2 and 3, a connecting rod 146 is slidably inserted through one end of the push rod 144 extending out of the sliding plate 141, and the connecting rod 146 simultaneously slidably penetrates through a plurality of push rods 144 along the direction of the side wall of the filtering tank 1. The connecting rod 146 connects the push rods 144 in series, so that when the connecting rod 146 is pulled, the connecting rod 146 drives all the push rods 144 and the scrapers 145 to slide simultaneously, and then the scrapers 145 scrape sand on the filter screen 11 simultaneously, thereby improving the scraping efficiency.

Referring to fig. 1 and 2, a blocking plate 147 is fixed at one end of the sliding plate 141 close to the push rod 144, and the blocking plate 147 slides in the filter tank 1 and covers the opening 121. When the water in the filtering tank 1 is drained into the water collecting tank 3, the blocking plate 147 blocks the opening 121 to prevent the water and the sand from being washed into the storage box 12 from the opening 121 by the impact of the water flow during the filtering.

The implementation principle of a mixing station drainage device in the embodiment of the application is as follows: when filtering sewage, pour into rose box 1 with sewage, sewage flows to filter screen 11 on, sewage along vertical direction flow direction filter screen 11, makes sewage filter through multilayer filter screen 11 to filter the grit of equidimension not, the grit rolls along filter screen 11 downwards, and the grit rolls out and falls into receiver 12 from opening 121 in, with reduce water and grit and flow into header tank 3 together, thereby improves the filter effect. When the sand and stone in the part of the filtered sewage is left on the filter screen 11, the push rod 144 is pulled, the push rod 144 drives the sliding plate 141 to slide in the guide groove 15, and the sliding plate 141 drives the sliding block 142 to slide in the sliding groove 143 of the adjacent sliding plate 141, so that the expansion plate 14 is in a contraction state. The push rod 144 drives the scraper 145 to slide on the filter screen 11, the scraper 145 slides and abuts against the gravel and enables the gravel to roll downwards along the inclined direction of the filter screen 11, and the gravel rolls out from the opening 121 and falls into the storage box 12, so that sewage filtered by the filter screen 11 is smoother.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
