Abstract
The invention discloses a center transmission mud scraper, and provides the center transmission mud scraper, which is simple in structure and high in reliability, and effectively prolongs the service life. The center transmission mud scraper is arranged inside a settling pond with a center column; the mud scraper comprises a drive device and a mud scraping arm; the drive device is connected to the upper part of the center column through a fixed support; the center transmission mud scraper also comprises a vertical rack which is in a frame structure; the vertical rack is sleeved on the center column; the center line of the vertical rack is consistent with the axis of the center column; the top part of the vertical rack is fixedly connected to the drive device; and the bottom part is connected with the mud scraping arm. The mud scraper disclosed by the utility model adopts the vertical rack structure to drive the mud scraping arm to rotate around the center of the settling pond; the mode of directly driving the mud scraping arm to act by the center transmission shaft in the prior art is changed; the situation that the center transmission shaft bears a large torque is avoided; the vertical rack is driven by a gear drive device; and the work stability of the mud scraper is improved and the service life is prolonged.
Description
Technical field
The present invention relates to water treatment facilities, relate in particular to the improvement to mud scraper structure.
Background technology
The center driving posture mud scraper that hangs down is widely used in that the circle of sewage treatment plant of water engineering is heavy determine in pond, will be deposited in sludge scraping collection at the bottom of pond to collecting mud pit, so that further processing.In prior art, mud scraper is positioned at the center of sedimentation basin, realize the driving to center power transmission shaft by drive unit, meanwhile be connected to the work that scraper arm on center driving axle starts to do circumferencial direction, then by sedimentation basin bottom sludge scraping to pool center collection mud sump, discharge outside pond with pump or by self-pressure by spoil disposal pipeline.In the course of work, because drive unit directly drives the work of center driving axle, the moment of torsion bearing is larger, and long-term use easily causes poor stability, has reduced the service life of equipment.
Summary of the invention
The present invention is directed to above problem, provide a kind of simple in structure, reliability is high, effectively improves the lifting center drive mud-scraper in service life.
Technical scheme of the present invention is: lifting center drive mud-scraper is located in the sedimentation basin with newel, and described mud scraper comprises drive unit and scraper arm, and described drive unit is connected to the top of described newel by hold-down support;
Also comprise the vertical frame that is frame structure, described vertical frame is set on described newel, and the center line of described vertical frame is consistent with the axis of described newel; The top of described vertical frame is fixedly connected on described drive unit, bottom connects described scraper arm.
Described drive unit comprises motor, driven wheel and driven gear, and described motor is by driven gear described in the described driving gear drives of driving, and described vertical frame connects described driven gear.
Described vertical frame cross section is square or circular.
Mud scraper in the present invention adopts the shelf structure that hangs down to drive scraper arm around sedimentation basin central rotation, has improved available technology adopting center driving axle and has directly driven scraper arm action, has avoided center driving bearing to be subject to larger moment of torsion; Drive the frame that hangs down to improve stability and the service life of mud scraper work by gear device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention,
Fig. 2 is the cutaway view of A-A face in Fig. 1;
In figure, 1 is sedimentation basin, the 11st, and newel, the 12nd, sludge out pipe, the 2nd, crane span structure, the 3rd, the frame that hangs down, the 4th, scraper arm, the 5th, scrape trowel, the 6th, motor, the 7th, rotating disc, the 8th, hold-down support, the 9th, cleaning shoe.
The specific embodiment
As shown in Figure 1-2, lifting center drive mud-scraper is located in the sedimentation basin 1 with newel 11 in the present invention, and described mud scraper comprises drive unit and scraper arm 4, and described drive unit is connected to the top of described newel 11 by hold-down support 8;
Also comprise the vertical frame 3 that is frame structure, described vertical frame 3 is set on described newel 11, and the center line of described vertical frame 3 is consistent with the axis of described newel 11; The top of described vertical frame 3 is fixedly connected on described drive unit, bottom connects described scraper arm 4, and the bottom of scraper arm 4 is connected with cleaning shoe 9, for scraping mud; Be provided with and collect mud pit in sedimentation basin 1 central bottom, the frame 3 that hangs down stretches in collection mud pit, is connected with and scrapes trowel 5 simultaneously in the bottom of the frame 3 that hangs down, and conveniently in collection mud pit, scrapes mud; In collection mud pit, connect in addition outside sludge out pipe 12, for spoil disposal; Above sedimentation basin 1, be also fixedly connected with crane span structure 2.
Described drive unit comprises motor 6, driven wheel and driven gear, and described motor 6 is by driven gear described in the described driving gear drives of driving, and described vertical frame 3 connects described driven gear; Driven wheel and driven gear have formed the rotating disc 7 being located on hold-down support 8.
Described vertical frame 3 cross sections are square or circular.
Drive unit in the present invention is made up of external toothing master gear, pinion, two stage reducer, hold-down support and drive unit bearing.A whole set of drive unit is arranged on newel 11, and center steering supporting simultaneously should be able to be born the rotation load of whole mechanisms.
The frame 3 that hangs down adopts box truss structure, and top is connected with centre-driven device with bolt, and bottom is connected with scraper arm 4, drives the frame 3 that hangs down to rotate together with scraper arm 4 by transmission mechanism; The frame 3 that hangs down adopts bar section of stainless steel to be welded into a whole, and scrapes under mud load in maximum, has enough strength and stiffness.
Operation principle of the present invention is: suspension in sewage is separated fall to pond at the bottom of, be fixed on the scraper arm 4 hanging down on frame 3 under the drive of drive unit, rotate around pond central axis, by being deposited on mud at the bottom of pond by cleaning shoe 9 collection mud pits, Gua Jizhichi center, by hydrostatic pressure, it is discharged from sludge out pipe 12.
