Description

Technical Field

[0001] The utility model belongs to the field of sewage treatment, relates to a sewage treatment device, and in particular to a sewage pool used for water treatment. Background Art

[0002] The treatment of urban sewage mainly adopts sewage purification. The sewage is concentrated to the sewage treatment plant through the city sewer pipes. The concentrated sewage is precipitated in the sewage pool. After a series of physical precipitation and chemical treatment, the impurities in the sewage can be effectively removed, thereby achieving the purpose of purifying the water quality.

[0003] When sewage is stored in a sewage pool for a long time, the mud and impurities in the sewage will settle at the bottom of the pool. The settled sludge needs to be treated regularly, otherwise a large amount of sludge accumulation will affect the water purification work. Commonly used sludge treatment structures mainly include central transmission thickening scrapers and peripheral transmission scrapers. The peripheral transmission scraper mainly installs two sets of sprocket transmission mechanisms on the inner side of a rectangular sewage pool, and then a plurality of sets of long strip scraper plates are installed on the sprocket transmission mechanism. As the sprocket mechanism rotates, the scraper plate fits the bottom of the pool, and the sludge can be effectively scraped into the sewage pipe. Then the sludge accumulated in the sewage pipe is pumped away by the sludge pump. However, when the sprocket transmission mechanism acts as a driving component to drive the scraper plate to move, the transmission chain of the sprocket mechanism is not rigid enough, causing the scraper plate to shake when moving, which in turn causes the scraper plate to fail to fit the bottom of the pool well, and the scraping effect is limited.

[0023] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0024] like Figure 1 and 2 As shown, the utility model provides a sewage pool for water treatment, comprising a pool 1.

[0025] The bottom of the pool 1 is provided with a plurality of arcuate grooves 2 arranged along the front-back direction, which are strip-shaped and have arc-shaped cross-sections. The plurality of arcuate grooves 2 are arranged along the left-right direction and are continuously connected, with the two ends being the starting end and the end end respectively.

[0026] Each arc groove 2 is equipped with a set of scraper assemblies. Figure 3 As shown, the scraper assembly includes a rotating shaft 31 and a rotating scraper blade 32. The rotating shaft 31 is located above the arc groove 2, and its two ends are respectively arranged on the front and rear side walls of the pool 1, and can rotate. The rotating scraper blade 32 is fixed to one side of the rotating shaft 31 through a connecting rod, and rotates with the rotating shaft 31. When it rotates into the arc groove 2, its outer side contacts the groove bottom of the arc groove 2. The rotating rotating scraper blade 32 scrapes off the sludge in the arc groove 2. The rotating directions of several rotating scraper blades 32 are the same, and the rotation in the arc groove 2 is all from the starting end to the end. Since several arc grooves 2 are continuously connected, the sludge scraped off by each arc groove 2 is moved to the next arc groove 2, that is, the sludge is scraped off from the first arc groove 2 and moved to the last arc groove 2 in sequence.

[0027] In a specific embodiment, the front end of the rotating shaft 31 extends out of the side wall of the pool 1, and two adjacent rotating shafts 31 are connected by a chain 41, and a plurality of chains 41 drive a plurality of rotating shafts 31 to rotate synchronously. Specifically, a sprocket 42 is fixedly sleeved at the end of the rotating shaft 31, and the chain 41 is sleeved on the sprocket 42 of two adjacent rotating shafts 31, thereby realizing the transmission between the rotating shafts 31. A motor 43 is fixed outside the pool 1, and the output shaft of the motor 43 is fixed to the rotating shaft 31 at the starting end to drive it to rotate. That is, the motor 43 drives the rotating shaft 31 at the starting end to rotate, and the rotating shaft 31 at the starting end then drives the other rotating shafts 31 to rotate synchronously in the same direction in sequence through the chain 41.

[0028] In a preferred embodiment, the side of the arc groove 2 at the starting end is smoothly connected to the top of the pool 1 through an inclined surface to avoid sludge accumulation due to the right angle between the arc groove 2 and the side wall of the pool 1.

[0029] The outer side of the rotating scraper blade 32 is inclined, and the inclination direction is opposite to the rotation direction thereof. When the rotating scraper blade 32 is separated from the arc groove 2, the inclined outer side can make the sludge slide into the next arc groove 2, thereby improving the efficiency of the sludge from one arc groove 2 to the next arc groove 2.

[0030] Among the plurality of rotating scraper blades 32, two adjacent rotating scraper blades 32 are centrally symmetrically arranged, so that when one rotating scraper blade 32 rotates to the end of its arc groove 2, the rotating scraper blade 32 of the next arc groove 2 just rotates to its starting end, and the two are connected, so that the sludge can be transferred more smoothly. Of course, the plurality of rotating scraper blades 32 can also be arranged in the same direction or other directions, and the sludge can also be scraped and moved.

[0031] like Figure 4 As shown, the bottom of the pool 1 is also provided with a drainage trough 5 arranged in the front-to-back direction, and the drainage trough 5 is continuously connected to the arc-shaped groove 2 at the end. A drainage port 11 is provided on the side wall of the pool 1, located at the rear end of the drainage trough 5. The drainage port 11 is connected to a mud pump.

[0032] A transmission belt 61 is provided above the sewage trough 5 in the front-to-back direction. A plurality of transmission scraper blades 62 are fixed on the transmission belt 61, and the height of the transmission scraper blades 62 matches the distance from the transmission belt 61 to the bottom of the sewage trough 5. The transmission belt 61 drives the plurality of transmission scraper blades 62 to operate, and the transmission scraper blades 62 that operate below the transmission belt 61 contact the bottom of the sewage trough 5 and move from front to back to scrape the sludge in the sewage trough 5 to the sewage outlet 11. The transmission scraper blades 62 cooperate with the sludge pump to better discharge the sludge.

[0033] In a specific embodiment, the transmission belt 61 is driven by a plurality of transmission wheels 63 disposed on the side wall of the pool 1. Figures 5 to 7As shown, the axle 631 of the transmission wheel 63 at the front end extends out of the side wall of the pool 1, and a driven bevel gear 71 installed on the side wall of the pool 1 is provided on the front side thereof, and the driven bevel gear 71 is connected to the axle 631 through a driven chain 72. A clutch 73 is installed on the front side of the pool 1 through a bracket 731, and the input end of the clutch 73 is connected to the rotating shaft 31 at the end through a driving chain 74, and a driving bevel gear 75 is fixed to the output end, and the driving bevel gear 75 is meshed with the driven bevel gear 71. The clutch 73 is an electromagnetic clutch 73. When the clutch 73 is connected, the rotating shaft 31 at the end drives the driving bevel gear 75 to rotate through the driving chain 74, and the driven bevel gear 71 rotates accordingly, and drives the transmission belt 61 to operate through the driven chain 72; when the clutch 73 is separated, the driving bevel gear 75 does not rotate with the rotating shaft 31.

[0034] In a preferred embodiment, the front end of the sewage chute 5 is smoothly connected to the side wall of the pool 1 through an arc surface to avoid sludge accumulation due to the right angle between the sewage chute 5 and the side wall of the pool 1.

[0035] The working process of the sewage pool of the utility model is as follows: sewage is discharged into the water pool 1 through a pipe, and then a proper amount of flocculant is added to the water pool 1, and then the motor 43 is started, and the plurality of rotating shafts 31 are driven to rotate synchronously through the chain 41, thereby driving the plurality of rotating scraper blades 32 to rotate, and the flocculant and sewage are fully stirred. After a period of time, the stirring is stopped to allow the sewage to settle. After settling for a period of time, the motor 43 is started again, and the sludge in the plurality of arc grooves 2 is scraped off in sequence by the rotating scraper blades 32 and moved to the sewage trough 5. The sludge pump and the clutch 73 are started, and the driving bevel gear 75 and the driven bevel gear 71 drive the transmission belt 61 to rotate synchronously with the rotation of the rotating shaft 31, and the running transmission scraper blades 62 scrape the sludge in the sewage trough 5 to the sewage outlet 11, and cooperate with the sludge pump to fully discharge the sludge.
