Description

Auxiliary movable mud scraping plate for mud suction machine of sedimentation tank

Technical Field

The utility model belongs to the environmental protection equipment field, concretely relates to sedimentation tank is auxiliary movable mud scraper for suction dredge.

Background

The sedimentation tank usually separates solid particles with specific gravity more than 1 in water by adopting a natural standing sedimentation mode. Taking a secondary sedimentation tank of a sewage treatment plant as an example, the average thickness of a sludge layer at the bottom of the secondary sedimentation tank is 0.4-0.9 m when the secondary sedimentation tank is in normal operation, and the hardening phenomenon can occur when the naturally settled activated sludge is kept still for about 48 hours. The conventional suction dredge is difficult to remove hardened sludge. Meanwhile, the sedimentation tank has a certain probability of falling into various hard blocky sundries. The bottom plate is very inconvenient to clean or maintain underwater equipment, and the emptying maintenance cost is high. The scraper blade of the sedimentation tank adopting the existing suction dredge is often set to be in a fixed form and is arranged at the rear position of the suction dredge pipe. Two kinds of fixed scraper blades that adopt at present have following drawbacks: the first fixed scraper is a scraper made of soft rubber materials and tightly attached to the bottom of the tank, and the scraper rubs with the bottom of the tank at any time during operation, so that the service life is relatively short, and the tank body needs to be emptied regularly to replace the scraper. The scraper has large water-facing area and large running resistance, and a series of problems of overload of a driving motor, abrasion of a driving wheel, deformation of a truss and the like can occur along with accumulation of sundries at the bottom of the pool; the fixed scraper blade of second kind sets up fixed scraper blade and is apart from the bottom of the pool certain distance, usually 20 ~ 25cm between the suction dredge of bold area bottom mud sink easily, harden, anaerobic fermentation, come-up, seriously influences sedimentation tank operation effect.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the drawings of the present invention will be combined below to clearly and completely describe the technical solutions of the present invention.

As shown in the attached drawings, the utility model provides a technical scheme as follows for realizing the above purpose: the utility model provides a sedimentation tank is auxiliary movable mud scraper for mud suction machine, includes sedimentation tank suction tube 1, its characterized in that: the pipe body one side of the mud suction pipe 1 is provided with a triangular front support 2, one end of the front support 2, which is far away from the mud suction pipe, is provided with a movable swing arm 4 which is hinged with the front support, the other ends of every two adjacent movable swing arms 4 are provided with bottom attaching scrapers 5 which are hinged with the front support, hinged parts at two ends of each movable swing arm 4 are provided with limiting parts 6, the other ends of the bottom attaching scrapers 5 are provided with triangular saw teeth 7 which are inclined upwards, and a pull rope 8 is arranged in the middle of each bottom attaching scraper 5.

Preferably, the top ends of every two adjacent front supports 2 are provided with first supporting rods 3 parallel to the bottom of the pool.

Preferably, a second support rod 3.1 parallel to the bottom of the pond is arranged at one end of each two adjacent front supports 2 far away from the sludge suction pipe 1.

Preferably, a third support rod 3.2 is arranged between every two adjacent movable swing arms 4.

Preferably, a pulley 10 is arranged in the middle of the first supporting rod 3, and the pull rope 8 extends out of the truss 103 on the water surface of the sedimentation tank through the pulley 10.

Preferably, a plurality of sliding blocks 9 are arranged on one side of the bottom attaching scraper 5 close to the ground.

Preferably, the interval of the saw teeth 7 in the length direction of the bottom attaching scraper 5 is 5-10 cm.

Preferably, the inclined plane of the saw teeth 7 forms an included angle of 15-75 degrees with the bottom attaching scraper 5.

The device comprises the following concrete implementation steps:

as shown in fig. 2, taking the circular radial flow type in-and-out sedimentation tank 101 as an example, a plurality of groups of sludge suction pipes 1 closest to the center of the tank should be arranged in the sedimentation tank from the sludge suction pipe 1 closest to the tank wall, and work simultaneously. As shown in figure 3, the movable swing arm 4 connected with two adjacent mud suction pipes 1 is a mechanism capable of moving independently so as to reduce the weight of the movable part and enable the movable part to be lifted by a self-hinged structure when meeting an obstacle. Every two movable swing arms 4 and the lower bottom-attached scraper 5 can independently rise under the action of foreign matters at the bottom of the pool and return to a bottom-attached state under the action of gravity after passing through the foreign matters. The movable swing arm 4 is connected with the bottom-attaching scraper 5 in a hinged mode with a limiting device, so that when the movable auxiliary scraper falls down, the bottom-attaching scraper 5 can be smoothly attached to the bottom plate of the sedimentation tank, the scraper teeth 7 are located at the rear as shown in figures 3 and 4, the scraper teeth cannot be overturned to other angles due to external force, the sliding block 9 made of wear-resistant rubber is arranged at the lower part of the bottom-attaching scraper 5, the bottom-attaching scraper 5 is slightly cushioned, and direct friction with the bottom of the tank is avoided. A small amount of sludge deposited at the bottom of the tank can lubricate the wear-resistant rubber and the bottom plate to a certain degree.

Through truss structure 103's rotation for paste end scraper blade 5 and clean the bottom of the pool, sawtooth 7 can cut the bottom mud that hardens, destroys its structure that hardens, and the mud pipe 1 that makes things convenient for the rear portion will become flexible mud and suck away, can also pull up activity swing arm 4 through stay cord 8, and artifical regulation pastes end scraper blade 5 height.
