Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an animal hair treatment device for sewage treatment. Background Art

[0002] Solid-liquid separation of farm wastewater is a very important part of farm wastewater treatment. It can effectively reduce the solid matter in the wastewater and reduce the load and cost of subsequent treatment. The main characteristics of farm wastewater are: high concentration of organic matter, high suspended matter, dark color, and a large amount of feces, urine and animal hair in the wastewater, which leads to a high concentration of ammonia in the wastewater.

[0003] At present, the solid-liquid separation equipment for aquaculture wastewater has a significant effect in treating large solid particles in wastewater, such as animal feces and feed residues, but the separation effect on fine substances such as animal hair is not ideal. The animal hair on one side of the filter in the equipment will accumulate more and more, eventually leading to blockage. The blockage of hair not only affects the efficiency of sewage treatment, but may also cause equipment damage and increase maintenance costs. Therefore, we proposed an animal hair treatment equipment for sewage treatment to solve the above problems. Summary of the invention

[0007] It is further defined that the movable seat is a frame-shaped structure with an opening at the upper end, the width of the opening is greater than the width of the supporting legs, the waist-shaped track passes through the middle of the movable seat, a groove is provided at the lower part of the movable seat, a driving motor is fixedly installed in the groove, a driving gear is fixedly installed on the output shaft of the driving motor, and a waist-shaped rack meshing with the driving gear is fixedly installed on the inner wall of the waist-shaped track. With such a structural design, when the driving motor is working, the output shaft drives the driving gear to rotate, and with the cooperation of the waist-shaped rack, the movable seat can be driven to move on the waist-shaped track.

[0008] It is further defined that the mounting frame includes a fixed arm, a switching tube and a fixed rod, the fixed arm is fixedly mounted on the upper part of the movable seat, an annular groove is provided at the end of the fixed arm, the switching tube is rotatably mounted in the annular groove, the fixed rod is fixedly mounted on the end of the switching tube away from the fixed arm, a bearing is fixedly mounted on the lower end of the fixed rod close to the movable seat, and the fixed rod is rotatably connected to the rotating shaft through the bearing. With such a structural design, the fixed rod is always kept in a vertical downward state under the action of gravity when the movable seat moves to the inflection point through the switching tube cooperating with the fixed rod.

[0009] The gear train is configured to be connected to a first gear and a second gear and to provide a plurality of gears, each of which is connected to a plurality of gears of the first and second gears, and the plurality of gears are connected to each other via a plurality of connecting rods. The second rotating rod is rotatably mounted on the fixed arm located on the front of the movable seat, one end of the second rotating rod passes through the adjacent connecting groove, and the other end passes through the fixed arm to the transfer cylinder. The second gear and the second friction wheel are respectively fixedly mounted on the two ends of the second rotating rod, and the third friction wheel is fixedly mounted on the end of the rotating shaft away from the fixed wheel. The second belt is sleeved on the second friction wheel and the third friction wheel.

[0010] It is further defined that a transfer column is fixedly installed at the opening of the transfer cylinder, and a rotating cylinder is rotatably installed on the transfer column.

With such a structural design, when the movable seat moves to the lower part of the waist-shaped track away from the scraper, the push column on the fixed rod can push the vertical rod to pull the pull rod, thereby pulling the scraper bar to move, so as to facilitate pushing the hair on the scraper bar into the receiving groove.

[0013] It is further defined that an annular air bag is provided at the transition point between the transfer tube and the fixed arm, an air pipe connected to the annular air bag is provided on the transfer tube, and an air pump is provided at the end of the air pipe.

[0015] The invention adopting the above technical solution has the following advantages:

[0016] 1. In the present invention, the movable seat cooperates with the waist-shaped track, the first transmission member and the second transmission member to drive the rotating roller and the rotating shaft to move along the waist-shaped track in the sewage pool.

[0054] The method of use of the present invention is as follows:

[0055] When in use, the sewage with solid impurities removed is discharged into the sewage pool 2, and the driving motor 331 drives the driving gear 332 to rotate, and cooperates with the waist-shaped rack 321 to drive the movable seat 33 to move in a counterclockwise direction on the waist-shaped track 32. At this time, the second rack 323 is meshed with the second gear 61, and the second gear 61 drives the second friction wheel 62 to rotate through the second rotating rod 6. The second friction wheel 62 cooperates with the second belt 63 to drive the third friction wheel 353 and the rotating shaft 34 to rotate counterclockwise, and the salvage plate 36 on the fixed plate 351 rotates accordingly, and the extended salvage bar is used to salvage the animal hair in the sewage;

[0056] When the movable seat 33 drives the scooping mechanism 3 to approach the scraper 21, the second gear 61 is disengaged from the second rack 323, and the air in the cylinder 7 is inflated and pressurized, so that the push rod 71 drives the friction block 72 to lock the rotating shaft 35 to prevent the rotating shaft 35 from rotating. The first gear 51 is meshed with the first rack 322. With the cooperation of the first transmission member, the rotating roller 34 rotates counterclockwise, and the salvage strips are contracted into the cavity of the rotating roller 34 under the action of force, so that the animal hair between the salvage strips can be removed to the rotating roller 34, reducing the adhesion of the animal hair. When the rotating roller 34 rotates, it contacts the comb tooth side of the scraper 21, and the scraper 21 can scrape the animal hair on the rotating roller 34.

[0057] When the rotating roller 34 and the scraper 21 are separated, the air in the cylinder 7 is deflated, the friction block 72 releases the lock on the rotating shaft 35, the first gear 51 is disengaged from the first rack 322, the second gear 61 is meshed with the second rack 323 again, the rotating shaft 35 rotates, and the salvage plate 36 contracted in the cavity sends the salvage bar out through the jack with the cooperation of the spring piece 352, and the salvage bar continues to salvage the animal hair in the sewage;

[0058] When the scooping mechanism 3 moves in the direction away from the scraper 21 under the waist-shaped track 32, the annular airbag 412 is inflated, so that the adapter tube 41 is locked with the annular slot, and the fixing rod 42 is in a locked state on the fixing arm 4. When the push column 421 on the fixing rod 42 contacts the vertical rod 261, the pull rod 26 will be pushed to move through the vertical rod 261, so as to pull the scraper 21 through the pull rope 25 to squeeze the compression spring 23. The scraper 21 is pulled away from the sewage pool 2, and the animal hair on the scraper 21 will be pulled into the receiving groove. After being pulled away, the movable seat 33 drives the scooping mechanism 3 to move to the lower corner of the waist-shaped track 32, and the push column 421 moves upward with the entire scooping mechanism 3 and disengages from the vertical rod 261. The tension at the pull rod 26 and the pull rope 25 is released, and the scraper 21 returns to its initial state under the elastic force of the compression spring 23, and cooperates with the scooping mechanism 3 to perform subsequent scooping work.
