Abstract
The utility model relates to an adjustable rake arm thickener, which comprises a middle shaft, rake arms, a plurality of hinge seats, hinge shafts, hinge pins and slant drawing rods. The upper end of the middle shaft is connected with a gear box and a power device, a supporting frame is mounted at the lower end of the middle shaft, the hinge seats are evenly distributed on the supporting frame surrounding an axle center, and each hinge shaft is a tube-shaped structure and horizontally mounted at one end of each rake arm. When assembling the thickener, users insert the hinge shafts of the rake arms into the hinge seats and penetrate the hinge pins into inner holes of the hinge seats and the hinge shafts. Further, a suspension frame is mounted at one end of each slant drawing rod, threads are arranged at the other end of each slant drawing rod, the suspension frame of each slant drawing rod is connected with a lifting lug preset on the middle shaft via a pin, a thread rod of each slant drawing rod is inserted into a center hole of the suspension frame preinstalled on each rake arm and fixed via a nut, and the angle of elevation of each rake arm can be adjusted by adjusting the fixed positions of the nut. The adjustable rake arm thickener has simple structure, convenient assembly and disassembly, can optionally adjust the angle of the rake arms, is not only convenient for site installation and ensures even stress of each rake arm, but also provides convenience for maintenance and conservation of the thickener.
Description
One, technical field
The utility model relates to concentrator, particularly a kind of concentrator of adjustable rake arm.
Two, background technology
Concentrator is a kind of equipment that solidliquid mixture is carried out gravity settling separation, is widely used in fields such as chemical industry, metallurgy, papermaking, pharmacy, sewage disposal.
Conventional concentrator is to be made of thickening pond, charging gear, device for discharging, power set, transmission device, axis and the rake arm that is installed in the axis bottom.Its operation principle is: the pasty material that needs to concentrate injects thickening pond through charging gear, the power set and the transmission device that are installed in pond central authorities drive the rotation of rake arm by axis, the material that has concentrated is harrowed material scraping plate under the arm and is scraped in the dump skip at center at the bottom of the pond, and discharges from the bucket end; The liquid of having clarified overflows from the overflow launder on thickening pond top.
For the ease of the material sedimentation, the bottom of thickening pond all be do tapered, make the rake arm of concentrator must be parallel with inclined-plane at the bottom of the pond could operate as normal, therefore, to guarantee when concentrator is installed that all rake arms have the identical elevation angle.Profile because of concentrator rake arm is bigger again, and is short several meters, long more than ten meter, must make up installation at the scene.
The rake arm of existing concentrator all is a stationary structure, its mounting means has two kinds: a kind of is to set up carriage in advance in the axis bottom, arm will be harrowed and carriage is fixed together to on-the-spot with screw again, this mode is difficult to make the accurate localization angle when the processing carriage, so its elevation angle of rake arm of installing is difficult to be consistent.Another kind of mode is directly will harrow arm at the scene and axis is welded together, be subjected to the restriction of on-the-spot mounting condition, it is identical also to cannot say for sure to demonstrate,prove each elevation angle of harrowing arm, so two kinds of mounting means all exist because of the rake arm is uneven, swing when unbalance stress causes the axis rotation, influence the defectives such as normal use of equipment.
Three, summary of the invention
In order to solve the problem that existing concentrator rake arm exists, the utility model provides a kind of adjustable rake arm-type concentrator, and it has adopted the hinge connected mode, and the elevation angle of rake arm can be adjusted arbitrarily, not only is convenient to on-the-spot the installation, and it is stressed evenly to have guaranteed respectively to harrow arm.
The technical solution of the utility model is as follows:
The arm-type concentrator of a kind of adjustable rake comprises axis and rake arm, and the upper end of axis connects gear-box and power set, and carriage is equipped with in the lower end of axis, and this concentrator also comprises hinge seat, hinge axis, joint pin and brace; Described hinge seat has several, and they are distributed on the carriage around the axle center, and described hinge axis is a tubular structure, and it laterally is installed in an end of rake arm; During the assembling concentrator, the hinge axis of rake arm is inserted in the hinge seat, and in the endoporus of hinge seat and hinge axis, penetrate joint pin, described brace one end is equipped with suspension bracket, the other end is provided with screw thread, and the suspension bracket of brace is connected by hanger default on pin and the axis, and the threaded rod of brace inserts in the centre bore of the suspension bracket of pre-installing on the rake arm, and fix with nut, can regulate the elevation angle of rake arm by the fixed position of adjusting nut.
The arm-type concentrator of adjustable rake described in the utility model, compare with the concentrator of existing fixed rake arm and to have the following advantages:
1. this hinge means is simple in structure, easy for installation, and rake arm angle is adjusted easily, thereby has avoided a series of problems because of the generation of rake arm unbalance stress.
2. the rake arm can be adjusted and dismantle, for the care and maintenance of concentrator provides convenience.
Four, description of drawings
Fig. 1 is the structural representation of the arm-type concentrator of adjustable rake.
Fig. 2 is the A-A view of Fig. 1.
Five, the specific embodiment
Referring to Fig. 1 and Fig. 2, the arm-type concentrator of a kind of adjustable rake comprises axis 3 and rake arm 9, and the upper end of axis 3 connects gear-box 2 and power set 1, and carriage 10 is equipped with in the lower end of axis 3.
The arm-type concentrator of adjustable rake also comprises hinge seat 11, hinge axis 12, joint pin 13 and brace 6, and described hinge seat 11 has several, and they are distributed on the carriage 10 around the axle center, and described hinge axis 12 is a tubular structure, and it laterally is installed in an end of rake arm 9.
During the assembling concentrator, hinge axis 12 is inserted in the hinge seat, and in the endoporus of hinge seat 11 and hinge axis 12, penetrate joint pin 13.
One end of described brace 6 is equipped with suspension bracket 5, the other end is provided with threaded rod 7, suspension bracket 5 on the brace 6 is connected by hanger 4 default on pin and the axis, threaded rod 7 on the brace 6 inserts in the centre bore of adjustable hanger 8, and fix with two nuts, can regulate the elevation angle of rake arm by the fixed position of adjusting two nuts.
The utility model is simple in structure, easy accessibility, and rake arm angle can be adjusted arbitrarily, not only is convenient to on-the-spot the installation, and it is stressed evenly to guarantee respectively to harrow arm, and provides convenience for the maintaining of concentrator.
