Description

Technical Field

[0001] The utility model relates to the technical field of scraper and suction mud equipment, in particular to a novel semi-bridge type peripheral transmission scraper and suction mud machine. Background Art

[0002] The semi-bridge peripheral transmission sludge scraper and suction machine is a kind of equipment used for sewage treatment. When working, the sewage is diffused from the water inlet pipe in the center of the pool (usually conical, which is conducive to the sludge gathering in the sludge collecting tank at the bottom of the pool) through the guide tube, and then flows out evenly to the surrounding in a radial shape. The suspended sludge is deposited on the bottom of the pool after sedimentation. The supernatant is discharged from the pool through the overflow pipe and the outlet tank to the clean water tank for further treatment. The crossbeam drives the sludge scraper from the bottom of the pool to the central sludge collecting tank, and is discharged to the outside of the pool through the sludge discharge pipe relying on the water pressure in the pool (or discharged to the outside of the pool through a submersible sewage pump, etc.).

[0003] Although the existing semi-bridge type peripheral transmission sludge scraper and suction machine has met the production needs to a certain extent, it still has the following technical problems due to structural limitations. Specifically, when the motor reduction mechanism drives the scraper blade to rotate through the crossbeam, the sludge on the bottom of the pool can only be scraped through the lower end of the scraper blade. When there are many impurities floating on the water surface in the sewage, the impurities will not be processed in time and will enter the clean water tank outside the pool through the overflow pipe, which will have an adverse effect on the subsequent use of water in the clean water tank by related equipment; for example, the production area pumps the water in the clean water tank through a water pump and pumps it out to the cooling pipe in the production area to cool the related production equipment. Due to excessive impurities entering the volute of the water pump, it causes greater resistance to the rotation of the blades in the volute, causing the motor to be damaged due to excessive load, or the impurities block the cooling holes of the cooling pipe, which has an adverse effect on production. In summary, it is very necessary to provide a semi-bridge type peripheral transmission sludge scraper and suction machine that can remove floating impurities in the sewage pool as much as possible.

[0020] Figure 1 , 2As shown in Figure 3, the sewage from the previous process flows out from the water inlet pipe 6 in the center of the sewage pool 10 (generally conical, which is conducive to the sludge collecting in the sludge collecting tank 8 at the bottom of the pool) through the guide tube 61 and diffuses, and then flows out evenly to the surrounding in a radial shape. The suspended sludge is deposited in the sludge collecting tank 8 at the bottom of the pool after sedimentation, and the supernatant is discharged from the pool through the overflow pipe 9 and the outlet tank to enter the clean water tank for further treatment; after the staff turns the handle of the power switch S to the left or right, the 1st and 2nd or 3rd pins of the power switch S are connected respectively, so that the motor decelerates When one or the other end of the motor running capacitor C of the mechanism M is energized, the rotating shaft of the motor reduction mechanism M will drive the cross beam 1 to drive the cross scraper 3 and the lower scraper 4 to rotate clockwise or counterclockwise (the positive and negative rotation is mainly to prevent the wires connecting the motor reduction mechanism A and the electric push rod from being entangled), and the sludge at the side end of the sewage pool is scraped into the mud collecting trough 8, and then the lower scraper 4 scrapes the sludge and part of the sewage at the bottom of the mud collecting trough 8 into the water inlet end of the sewage pump. After turning on the power switch of the sewage pump, the sewage pump extracts the sludge and sewage mixture and discharges it out of the pool. In the initial state of the present invention (including after the sludge at the lower end of the sewage pool is scraped out by the scraper), the right end of the collecting shell 71 is horizontally located on the left side of the overflow pipe 9 of the sewage pool 10 (with a very small distance), and the outer diameter of the right end of the collecting shell 71 is larger than the inner diameter of the overflow pipe 9, so that the clear liquid at the upper end of the sewage pool flows out through the filter holes of the collecting shell 71 and the overflow pipe 9 (when the crossbeam rotates, the clockwise rotating collecting shell 71 will actively filter the impurities on the water surface), and when the clean water flows in and out of the collecting shell 71, the impurities will be filtered by the filter holes and remain in the collecting shell 71. After the AC 220V power supply enters the power input end of the power module A1, the power output end of the power module A1 outputs a DC 12V power supply and enters the power input end of the power switch S2. When the right end of the collection shell 71 of the new type is horizontally located on the left side of the overflow pipe 9 of the sewage pool 10, or when the scraper is controlled to rotate clockwise, the staff turns the handle of the power switch S2 to the left, and the 1, 2 and 3, 4 pins of the power switch S2 are connected respectively, so that the positive and negative power input ends of the two sets of electric push rods M2 are powered, and the push column drives the movable plate 74 to move up to the stop point and then turns off the power switch S2, so as to prepare for the subsequent filtration of impurities in the clear liquid at the upper end of the sewage pool. When the scraper is controlled to rotate counterclockwise, the staff turns the handle of the power switch S2 to the right, and the 1, 2 and 5, 6 pins of the power switch S2 are connected respectively, so that the negative and positive power input ends of the two sets of electric push rods M2 are powered, and the push column drives the movable plate 74 to move down to the stop point and then turns off the power switch S2, so that the movable plate 74 completely blocks the front side end of the collection shell 71, preventing the water from discharging the impurities in the collection shell in the reverse direction when the collection shell rotates counterclockwise.

[0021] Figure 1 , 2As shown in FIG. 3 , after a period of time, when the amount of impurities in the collecting shell 71 is large, the shielding plate (movable plate 74) is closed, and the staff turns the handle of the power switch S1 to the right, the 1 and 3 pins of the power switch S1 are connected, so that the other end of the motor operating capacitor C1 of the motor reduction mechanism AM1 is energized, and the shaft of the motor reduction mechanism AM1 will rotate counterclockwise, and the external thread of the screw rod 72 acts on the internal thread of the thread hole of the sliding plate 73, and the sliding plate 73 moves from the left stop point to the right to compress the impurities in the collecting shell 71. After turning off the power switch, the sliding plate no longer compresses the impurities, and then the staff controls the sliding plate to move to the left for a distance (about 2 cm). After the staff controls the movable plate to move upward, the compressed impurities can be conveniently removed at the side end of the sewage pool shore (generally, the power switch is turned off after 1 minute of compression work). Finally, the staff turns the handle of the power switch S1 to the left, and the 1 and 2 pins of the power switch S are connected. In this way, one end of the motor operating capacitor C1 of the motor reduction mechanism AM1 is energized, and the shaft of the motor reduction mechanism AM1 will rotate clockwise. The external thread of the screw rod 72 acts on the internal thread of the thread hole of the sliding plate 73, and the sliding plate 73 moves from the right end to the left stop point and returns to the initial position, then turns off the power switch to prepare for the next compression.

[0022] Through the above, the utility model can not only scrape out and discharge the sludge at the bottom of the sewage pool, but also filter and collect impurities floating on the water surface through the impurity collection mechanism, and when the amount of impurities is large, the staff can compress and collect the impurities through the motor reduction mechanism A, the screw rod, the sliding plate, etc., thereby minimizing the amount of impurities entering the clean water pool and reducing the adverse effects of impurities in the clean water pool on the next production process equipment.

For those skilled in the art, it is obvious that the utility model is limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
