Description
Technical Field
The invention relates to the technical field of sewage treatment, in particular to an environment-friendly sewage sludge recovery device.
Background
With the acceleration of the urbanization process, the production amount of sewage is increased year by year. In order to reduce the pollution of sewage to the environment, a large amount of financial resources are invested in countries and enterprises, and a plurality of sewage treatment plants are established to treat urban sewage. In sewage treatment, a lot of sludge is produced, and sludge in some types of sewage has the advantage of recycling, and the sludge can be used as fertilizer and even used as raw materials for combustion power generation.
In the prior art, when separating sludge and sewage, a sewage treatment device is generally adopted to carry out preliminary filtration on the sludge and the sewage, a filter screen is adopted in the sewage treatment device, a proper flocculating agent is put in to precipitate the sludge in the sewage, and then the filter screen is detached to recycle the sludge on the filter screen. However, the following problems exist: because sewage and mud get into together and make some mud can be attached to on sewage treatment plant's the inside wall to make the mud volume on the filter screen reduce, finally lead to the recovery volume of mud to reduce.
Therefore, a device capable of scraping the sludge on the inner side wall of the sewage treatment device is urgently needed.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides the environment-friendly sewage sludge recovery device which has the characteristic of being capable of scraping sludge on the inner side wall of a sewage treatment device.
In order to solve the technical problem, the invention is solved by the following technical scheme: an environment-friendly sewage sludge recovery device comprises a treatment box, wherein the top of the treatment box is provided with a feed inlet, a motor is arranged outside the side wall of the processing box, the output end of the battery is coaxially connected with a rotating shaft, the rotating shaft is positioned in the processing box, the rotating shaft is coaxially connected with a stirring wheel and is also linked with at least two groups of crank mechanisms, one end of each crank mechanism is provided with a mud scraping block, the mud scraping block is tightly attached to the inner side wall of the treatment box, a primary filter screen and a secondary filter screen which are arranged up and down are arranged in the treatment box, the primary filter screen is also provided with rotating blocks which are arranged at the two ends in a rotating way, when the rotating blocks rotate, the gap between the rotating blocks and the primary filter screen forms a space for the mud scraping block to pass through, the rotating block is further provided with a torsion spring, the secondary filter screen is further provided with a water diversion block for guiding sewage to wash to the sludge scraping block, and the side wall of the treatment box is further provided with a cam for shaking the sludge scraping block.
Further preferably, the crank mechanism comprises a main shaft, a rotary table is arranged on the main shaft, a connecting rod is hinged to the rotary table, and the other end of the connecting rod is fixedly connected with the mud scraping block.
Further optimize, the pivot is the coaxial coupling still has first belt pulley, coaxial coupling has the second belt pulley on the main shaft, connect through the belt between first belt pulley and the second belt pulley.
Further optimize, the cross-sectional shape of scraping the mud piece includes horizontal portion and vertical portion, the inseparable laminating of vertical portion handles the incasement wall, be connected with circular arc portion between horizontal portion and the vertical portion, the opening orientation of circular arc portion sets up downwards.
Further optimize, the water diversion piece includes vertical portion and water diversion portion, the water diversion portion is for being cross-section triangle-shaped setting, triangle-shaped's hypotenuse is terminal to be in relative setting when bottommost with scraping the mud piece.
Further optimize, the bottom of handling the case sets up the supporting seat, it is equipped with the delivery port to handle the bottom of the case.
Further optimize, it has the revolving door to articulate on the case lateral wall to handle, primary filter screen and secondary filter screen all detachably set up in handling the incasement.
The method comprises the following specific operation steps: pour sewage and mud into to the treatment box through the feed inlet in, some mud in the sewage are to attaching to on the lateral wall of handling the case, some mud can fall into in the stirring wheel in addition, then starter motor, the motor rotates and drives the pivot and rotate, the pivot rotates and drives the stirring wheel and rotate, thereby tentatively stir sewage and through sewage transportation to elementary filter screen on, the rotation of stirring wheel can be so that the mud that falls into the stirring wheel also drops to elementary filter screen on, elementary filter screen carries out the first separation to mud sewage this moment, bold mud can't pass through elementary filter screen.
When the rotating shaft rotates, the crank mechanism is driven to move, and the connecting rod rotates along with the rotation of the rotating disc, so that the mud scraping block is driven to reciprocate from top to bottom. The turning block initial state flushes with primary filter screen for sewage and mud can't pass through, but when driving mud downstream along with scraping the mud piece, the vertical portion of scraping the mud piece can contradict the turning block, thereby makes the turning block take place to rotate, and the turning block rotates certain angle, makes the turning block and primary filter screen form the space, makes the connecting rod with scrape the mud piece and pass through, because the setting of torsional spring, makes the turned angle of turning block cooperate with the mud piece and the connecting rod of scraping of motion all the time. Until the mud scraping block moves to the lowest limit position. The cam is started to rotate, the cam rotates to enable the mud scraping block to automatically shake, so that the mud on the mud scraping block is vibrated to fall down, and the mud falls on the secondary filter screen. Meanwhile, the sewage filtered by the primary filter screen is enabled to flow to the arc part of the sludge scraping block due to the action of the water distribution plate, the sludge on the sludge scraping block is impacted by water and better falls off, and finally the sludge and the sewage are separated through secondary filter screen filtering, and the sewage is discharged from the water outlet. Then the user is through opening the door of handling the case lateral wall, dismantles primary filter screen and secondary filter screen, collects the mud on primary filter screen and the secondary filter screen, and the recycle of being convenient for makes fertilizer or as the raw materials of burning electricity generation.
When the connecting rod and the mud scraping block return, the rotating block resets under the action of the torsion spring and is flush with the primary filter screen again.
The invention has the beneficial effects that: 1. adopt and scrape the mud piece and strike off the mud of handling the case lateral wall to adopt crank mechanism to drive and scrape mud piece reciprocating motion from top to bottom, can reduce the mud and adhere to the possibility of handling the case lateral wall, increase the recovery volume of mud. 2. Through setting up the turning block, set up the torsional spring on the turning block, make the turning block and scrape mud piece or connecting rod through the effect of torsional spring and keep the state of laminating, rotate by the turning block and make and rotate certain angle, the turning block supplies to scrape mud piece and connecting rod through with elementary filter screen formation space, has guaranteed that elementary filter screen both can accomplish the prefilter to mud sewage, can make again to scrape the mud piece and pass primary filter screen and carry out reciprocating motion from top to bottom. 3. Through the setting of water diversion plate, utilize the sewage impact after having been filtered by primary filter screen to scrape mud piece under the vibrations of mud piece intermittent type nature are scraped in the cam rotation drive, thereby strike the mud that is difficult to drop on scraping the mud piece, make mud drop on secondary filter screen.
