Abstract

The utility model discloses a torque automatic tacking sliding rake lifting mud scraper used for environmental-friendly mud treatment which mainly comprises a mud scraping rake (11), a torque automatic tacking device (17), a lifting worm gear (12), a lead screw (13), an spline shaft (14), a mud scraping worm gear and worm transmission part (15), a spindle part (8), a flow stabilization flocculation part (7), a lifting worm gear (12), a control part (6), and the like. The utility model has the advantages of continuous mud scraping and collection, accurate torque detection, high automaticity, long service life, convenient maintenance, and the like.

Description

Moment of torsion slides from motion tracking and carries the rake mud scraper

Technical field

The utility model relates in the water treatment system in fields such as a kind of environmental protection and ore dressing, is used for scraping collection, concentrating of mud and ore pulp, and the moment of torsion that reaches the clarification medium slides from motion tracking and carries the rake mud scraper.

Background technology

At present, the problem of existing mud scraper existence: 1, moment of torsion testing agency accuracy of detection is not high, and mechanism is easy to failure.2, the moment of torsion detection signal can not be realized teletransmission, does not realize the central station of floating dock centralized Control.3, mud rake promotes and adopts singly-bound to slide, and stability is not high.4, have only machine overload protection or instrument to show protection.5, be not the mud rake of imitative type design at the bottom of the pond, it is bad to scrape the mud effect, and efficient is not high.

The utility model content

The purpose of this utility model is can effectively overcome above-mentioned five shortcomings of organic type by a kind of novel mud scraper of design.It is mainly crossed torque protection device, carries the rake motor, carries the rake stopping means, control section, current stabilization flocculation part, main shaft portion, secondary rake, downflow weir, mud scraper, lifting worm gear, leading screw, splined shaft, scraped mud worm and gear running part, moment of torsion detection springs, the automatic instrument of moment of torsion, pointer and form by truss, driving motor reductor, electromechanical appearance; It is characterized in that: promote worm gear core band T type internal thread, promote worm gear and be rotatably connected by T type internal thread and doing up and down on the straight-line leading screw, leading screw and splined shaft, mud scraper are solidly installed.

Moment of torsion slides from motion tracking and carries the rake mud scraper as described, it is characterized in that: mud scraper is by the imitative type design of log spiral.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model moment of torsion being carried the rake mud scraper from the motion tracking slip is described in further detail:

Fig. 1 carries the front view of rake mud scraper for the utility model moment of torsion is slided from motion tracking

Fig. 2 is for carrying the A-A of rake mud scraper Fig. 1 to the view enlarged drawing to the utility model moment of torsion from the motion tracking slip.

Fig. 3 is for carrying the B-B of the Fig. 2 that harrows mud scraper to the view enlarged drawing to the utility model moment of torsion from the motion tracking slip.

The specific embodiment

The detail and the working condition that the utility model proposes below in conjunction with the explanation of the relief of specification.

The working condition that the utility model moment of torsion is carried rake mud scraper (19) from the motion tracking slip is such: shown in Figure 1, mud scraper (19) integral hanging in truss (1) in the heart, driving motor reductor (2) is by scraping mud worm and gear running part (15), main shaft portion (8) drives mud scraper (11) and is parked in the collection of scraping that carries out mud or ore pulp when clockwise direction begins on " 0 " position of carrying rake, moment of torsion autotracker (17) detects the variation of scraping the mud resistance, join the electromechanical appearance of torque sensor and display pointer (18) and cross torque protection device (3), mud scraper (19) is enlarged into the output signal of telecommunication that gauge pointer (18) shows signal and 4-20mA because of the middle worm screw micro-displacement signal of mud worm and gear running part (15) of scraping that change in resistance produces, the resistance that runs into mud or ore pulp increases overrate, carry rake motor (4) by control section (6) startup and promote worm gear (12) rotation by driving, promote worm gear (12) core band T type internal thread, make T type internal thread drive leading screw (13) and do rectilinear motion up and down, leading screw (13) and splined shaft (14), mud scraper (11) is solidly installed, and leading screw (13) is done and mentioned the load that mud scraper (11) alleviates mud scraper (19) when making progress rectilinear motion; Get back to " 0 " position when the resistance of mud or ore pulp is reduced to the rated value rake that can begin automatically to fall, successively scrape collection mud or ore pulp from top to bottom; Have moment of torsion machinery and instrument, electronics and control the triple protection device automatically, can carry according to the size of super moment of torsion when having guaranteed to scrape the super moment of torsion of collection, fall to harrowing or shutdown.

The imitative type mud scraper (11) of the log spiral of optimal design had both improved efficient at the bottom of the pond, had guaranteed to scrape the mud effect again.

This practicality is carried rake mechanism because be provided with novel moment of torsion from the motion tracking slip; can accurately detect and run into the resistance of scraping mud; just in case when running into moment of torsion transmission mechanism can't overcome when big; cut off circuit or cut off safety pin; thereby protect driving motor reductor (2) not to be damaged effectively, ensure the efficient operation of thickener.

Claims

1, a kind of moment of torsion that is used for the environmental protection Treatment of Sludge slides from motion tracking and carries the rake mud scraper, by truss (1), driving motor reductor (2), electromechanical appearance is crossed torque protection device (3), carry rake motor (4), carry rake stopping means (5), control section (6), current stabilization flocculation part (7), main shaft portion (8), secondary rake (9), downflow weir (10), mud scraper (11), promote worm gear (12), leading screw (13), splined shaft (14), scrape mud worm and gear running part (15), moment of torsion detection springs (16), the automatic instrument of moment of torsion (17), pointers (18) etc. are formed mud scraper (19); It is characterized in that: promote worm gear (12) core band T type internal thread, promote worm gear (12) and be rotatably connected by T type internal thread and doing up and down on the straight-line leading screw (13), leading screw (13) is solidly installed with splined shaft (14), mud scraper (11).

2, moment of torsion as claimed in claim 1 slides from motion tracking and carries the rake mud scraper, it is characterized in that: mud scraper (11) is by the imitative type design of log spiral.
