Background
Along with the development of society and the progress of science and technology, the sewage treatment industry is gradually becoming intelligent, and intelligent water affairs are increasingly relying on an online monitoring system of water quality, so that the stability of the online monitoring system is also gradually becoming the key point of intelligent water affairs. The water quality analysis instrument in the on-line monitoring system is often matched with a simple screen and a pretreatment box body, equipment such as a stirrer, an electromagnetic valve and the like are arranged in the box body, the pretreatment box body stirrer is started when the analysis instrument is used for sampling, the electromagnetic valve is started to communicate with a small pipe after stirring, and finally the water quality analysis instrument is sucked into the instrument for detection. In the prior art, water samples to be detected are cleaner after being treated by a sewage plant, so that the pretreatment requirements of the devices can be met by using the simple pretreatment device, but the pretreatment requirements of the water inlet devices with more particles and sludge cannot be met, the analysis devices of the devices caused by blockage of the suction pipes by the particles are very frequent, and the manual maintenance cost is high. Therefore, how to pretreat sewage more effectively to remove impurities inside is a problem that we have to deal with.
The Chinese patent bulletin number is: the invention patent of CN102225253B discloses a swinging type sewage accelerating sedimentation tank which can accelerate the sedimentation process in sewage treatment, clarify water and improve the sewage treatment effect. The movable sedimentation tank body is arranged on the horizontal shaft bracket through the ear shaft bracket, and the mechanical tilting device is connected with the tank body. When the sewage reaches a destabilizing critical state, the tilting mechanism is started to swing the movable tank body to generate centrifugal motion. By utilizing the deformation property, inertial property, viscosity and boundary property of fluid, the aggregation state and concentration distribution of micro-flocculation nuclei in critical destabilization state are changed, so that the density of the flocculation nuclei in the local area is increased, the distance is reduced, more flocculation nuclei are promoted to be mutually adsorbed, crosslinked and coalesced, large-size and large-mass flocculation bodies are formed to be settled, suspended matters in water bodies are reduced, and sewage is clarified and purified. The whole precipitation process has the advantages of short time, good effect, low energy consumption, low cost, environmental protection, simplicity and easy implementation.
In the above patent, although centrifugal motion can be generated by the tilting mechanism to further accelerate the precipitation of impurities, in practical application, we find that there are certain disadvantages, such as:
1. if the patent is applied to the aspect of sewage pretreatment of a water inlet instrument, the patent is inconvenient for detecting the precipitated sewage;
2. the tilting mechanism in the patent has complex structure, high cost and difficult maintenance after damage;
3. the tilting mechanism in the above patent requires an electric drive, wasting energy.
Based on this, we propose a pretreatment device for sewage, which is hoped to solve the shortcomings in the prior art.

and (3) water inlet: opening the water inlet valve 3, closing the bypass valve 7 and the discharge valve 10, and allowing the sewage passing through the water inlet pipe 2 to flow into the treatment tank 1 through the first branch pipe 4 and the second branch pipe 5, and accumulating in the treatment tank 1;
precipitation: closing the water inlet valve 3, opening the bypass valve 7, depositing sewage in the treatment tank 1, depositing sundries at the bottom of the treatment tank 1, and gradually clarifying the sewage above the treatment tank 1;
sampling: the clear sewage can be sampled through the sampling tube 11 and the conveying tube 12, so that excessive impurities in the sewage are prevented from blocking the sewage analysis instrument, and the cartridge filter 13 can further filter the sewage to remove the impurities in the sewage;
and (3) emptying: closing the water inlet valve 3, opening the bypass valve 7 and the emptying valve 10, and allowing sewage passing through the water inlet pipe 2 to flow away through the bypass pipe 6, and discharging the sewage in the treatment tank 1 through the emptying pipe 9, so that the sewage in the treatment tank 1 is conveniently emptied;
the sewage flowing out of the first branch pipe 4 and the second branch pipe 5 flows into the treatment tank 1 in two ways, under the blocking of the first water baffle 14 and the second water baffle 15, the two ways of sewage flow around the first water baffle 14 and the second water baffle 15 in a vortex form, the guide threads 16 arranged on the outer walls of the first water baffle 14 and the second water baffle 15 can further strengthen the vortex flow state of the sewage, the sewage is in vortex roll and can accelerate the precipitation of impurities in the sewage, the time waiting for the precipitation of the sewage is shorter, and additional power output is not needed;
the sewage in the treatment tank 1 is in vortex rolling to accelerate the precipitation of impurities in the sewage, the precipitated impurities pass through the precipitation holes 21 and are positioned in the precipitation bucket 8 and below the fixed disc 18, the sewage in the treatment tank 1 is in vortex rolling to push the blades 20 and the rotating column 19 to rotate, the blades 20 rotate to clear the precipitation holes 21 through the cleaning brushes 24 at the bottoms of the blades, the impurities are prevented from blocking the precipitation holes 21, the rotating column 19 rotates to drive the rotating shaft 22 to rotate, the rotating shaft 22 rotates to drive the cutting blades 23 fixedly arranged on the outer walls of the rotating shaft 22 to rotate, the cutting blades 23 rotate to crush the impurities in the precipitation bucket 8, the volume of the impurities is smaller, the impurities are prevented from blocking the blow-down pipe 9, and further treatment of the sewage is facilitated;
the inner wall of sedimentation hole 21 has seted up side groove 25, and the inner wall of side groove 25 rotates and sets up pulley 27, and when debris passed through sedimentation hole 21, debris passed sedimentation hole 21 more easily under pulley 27's guide effect, can not take place to block up, and the annular blade 28 of pulley 27 outer wall can cut the debris through sedimentation hole 21, prevents on the one hand that debris from too big blocking up sedimentation hole 21, on the other hand also plays the effect of pre-crushing.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
