Mud scraper for water treatment
Technical Field
The invention relates to the technical field of water treatment equipment, in particular to a mud scraper.
Background
A mud scraper is a machine for cleaning mud from a river channel, is used in a circular sedimentation tank with larger diameter in municipal sewage treatment plants, water supply plants and industrial wastewater treatment, and is used for removing the mud settled at the bottom of the tank and skimming scum on the surface of the tank.
And in prior art, the in-process of mud is continuously scraped at the mud scraper, and the mud of bottom of the pool can suspend for the mud volume that the mud scraper can scrape away reduces, has reduced mud scraping efficiency.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides the mud scraper for water treatment, which has a compact structure and high mud scraping efficiency.
The invention is realized by adopting the following technical scheme: mud scraper for water treatment, including mounting bracket, crossbeam, mud scraper and driving motor, driving motor locates the top, the drive of mounting bracket the crossbeam rotates, the mud scraper is located the bottom of crossbeam, the bottom of mud scraper is equipped with scraper and mud presser, mud presser includes briquetting and briquetting actuating mechanism, briquetting actuating mechanism is including even motor and connecting rod, the cover is equipped with the pinion on the output shaft of motor, the bottom of connecting rod with briquetting fixed connection, the top of connecting rod be equipped with pinion engagement's rack.
The pressing block is arranged in the center of the bottom of the mud scraper, and the scraper is arranged on the side, back to water, of the bottom of the mud scraper.
The bottom of the mud scraper is also provided with a pair of sliding rods, and the pressing block is sleeved on the sliding rods.
The motor is an underwater motor and is arranged at the top of the mud scraper, and the connecting rod penetrates through the mud scraper through a through hole and is connected with the pressing block.
The bottom of the mud scraper is faced with water one side and still is equipped with the clamp plate, the clamp plate includes vertical bracing piece and locates the preforming of bracing piece bottom, the preforming is the circular-arc of kickup.
Compared with the prior art, the motor drives the half gear to rotate, when the teeth of the half gear are meshed with the rack, the motor drives the connecting rod to move upwards, the pressing block is pulled to move upwards, when the toothless part of the half gear faces the rack, the rack is separated from the half gear, the pressing block is pressed downwards under the action of gravity, the bottom sludge is compacted, the compacted sludge is shoveled by the scraper and is discharged through the drain pipe, the sludge suspension is avoided, and the sludge scraping effect is effectively improved.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
As shown in fig. 1-4, mud scraper for water treatment, including mounting bracket 1, crossbeam 2, mud scraper 3 and driving motor 4, be equipped with transmission shaft 9 on driving motor 4's the output shaft, transmission shaft 9 is connected with crossbeam 2, driving motor 4 locates top, the drive of mounting bracket 1 crossbeam 2 rotates, mud scraper 3 locates crossbeam 2's bottom, mud scraper 3's bottom is equipped with scraper 5 and mud presser, mud presser includes briquetting 61 and briquetting 61 actuating mechanism, briquetting 61 actuating mechanism is including linking motor 62 and connecting rod 63, the cover is equipped with semi-gear 64 on motor 62's the output shaft, the bottom of connecting rod 63 with briquetting 61 fixed connection, the top of connecting rod 63 be equipped with the rack 65 of semi-gear 64 meshing. The motor 62 drives the half gear 64 and rotates (half gear 64, the outer fringe of gear only has general tooth promptly), when the tooth of half gear 64 and rack 65 meshing, motor 62 drives connecting rod 63 upward movement, just also stimulate briquetting 61 and shift up, when the part of the tooth of half gear 64 no tooth is towards rack 65, rack 65 and the separation of half gear 64, briquetting 61 pushes down under the action of gravity, the realization is to the compaction of bottom mud, rethread scraper 5 shovels the compacted mud, discharge through the blow off pipe, the mud suspension has been avoided, the mud scraping effect has effectively been improved.
The pressing block 61 is arranged in the center of the bottom of the mud scraping plate 3, and the scraper 5 is arranged on the side, back to the water, of the bottom of the mud scraping plate 3. That is, during the operation, the sludge suspended in the sludge is first compacted by the briquette 61 and then scooped up by the scraper 5.
The bottom of the mud scraper 3 is also provided with a pair of sliding rods 7, and the pressing block 61 is sleeved on the sliding rods 7. The slide rod 7 is arranged, so that the pressing block 61 can be limited when sliding up and down, and the pressing block 61 is prevented from generating horizontal displacement under the impact of water flow.
The motor 62 is an underwater motor 62 and is arranged at the top of the mud scraper 3, and the connecting rod 63 penetrates through the mud scraper 3 through a through hole to be connected with the pressing block 61. The underwater motor 62 has good sealing performance, can prevent the motor 62 from being soaked in water to cause short circuit, and ensures that the pressing block 61 can be reliably lifted.
The bottom of the mud scraper 3 is facing to water and is also provided with a pressing plate, the pressing plate comprises a vertical supporting rod 81 and a pressing sheet 82 arranged at the bottom of the supporting rod 81, and the pressing sheet 82 is in an arc shape and bends upwards. The suspended sludge can be further pressed down by the arc-shaped pressing piece 82 and then compacted by the pressing block 61.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
