Description
Technical field
The utility model belongs to mining equipment technical field, relates in particular to the anti-blocking guarantor of chute under a kind of sculping screen
Protection unit.
Background technique
Coalmine Coal Preparation Plant Dense-medium system have cover sculping screens, be each responsible for raw coal after dual medium cyclone dressing cleaned coal, in
The de-mediated task of coal, spoil, the sculping screen are linear vibrating screen, amplitude 4.5-5.5mm, frequency 15Hz.Sieve is divided into three ranks
Section: closing Jie's section, dilute Jie's section and product section, and qualified medium stream closes Jie's section chute by sculping screen and returns to conjunction Jie's bucket under normal circumstances,
It is caused blockages if closing Jie's section blanking chute notch, will lead to a large amount of medium waters and be full of feeding chute, it is then excessive, it causes to give birth to
Production accident, processing is extremely difficult, seriously affects Dense-medium system production, how to be capable of the hair that anti-anti-avulsion sieves lower chute blocking phenomenon
It is raw, it is our problems to be solved.
Utility model content
For various deficiencies of the prior art, it is proposed that a kind of structure is simple and chute under sculping screen can be effectively prevent stifled
The protective device of plug.
To achieve the above object, the utility model provides the following technical solutions:
Chute anti-blocking-up protection apparatus under a kind of sculping screen, is used cooperatively with relay and control cabinet, slips under sculping screen
Slot position is in the lower section of sculping screen, and its structure in the form of slot, and chute anti-blocking-up protection apparatus includes floating ball and approaches under the sculping screen
Switch, the floating ball is located at lower chute bottom, described to be located on the outside of lower chute walls close to switch, one end of the floating ball and buoy
It is connected, the other end of the buoy is connected after lower chute walls with contactor, and the lower section of the contactor is equipped with matched
Close to switch, and the lower end of the contactor and described close to being equipped with interval between switch is described to pass through relay close to switch
Device is connect with control cabinet.
Further, the lower chute walls are equipped with for the perforative through-hole of buoy.
Further, the through-hole is arranged along the short transverse of the lower chute walls.
Further, the buoy is along horizontally arranged.
Further, it is fixed on the outside of the lower chute walls and below the through-hole for the support for lifting buoy
Bar.
The beneficial effects of the utility model are:
Structure is simple, install convenient, and floating ball is installed in lower chute, close switch is installed outside lower chute, instantly chute memory
In medium flow field, floating ball floats immediately, and i.e. and close to switch contact, sculping screen stops working contactor, effectively prevent accident
Expand, reduce the labor intensity of worker, greatly reduce the time used in processing accident, reduces coal mine loss.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model original state；
Fig. 2 is the structural schematic diagram of utility model works state.
In attached drawing: being slipped under chute, 7- under the close switch of 1- floating ball, 2-, 3- buoy, 4- contactor, 5- pressure pin, 6- sculping screen
Cell wall.
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below with reference to the utility model
Attached drawing carries out clear, complete description to the technical solution of the utility model, and based on the embodiment in the application, this field is general
Logical technical staff other similar embodiments obtained without making creative work, all should belong to the application
The range of protection.In addition, the direction word mentioned in following embodiment, such as "upper" "lower" " left side " " right side " etc. are only with reference to attached drawing
Direction, therefore, the direction word used is for illustrative and not limiting the invention.
The utility model is described in further detail with preferred embodiment with reference to the accompanying drawing.
Embodiment one:
As shown in Figs. 1-2, chute anti-blocking-up protection apparatus under a kind of sculping screen makes with relay and control cabinet cooperation
With chute 6 is located at the lower section of sculping screen, and its structure in the form of slot under sculping screen.Chute anti-blocking-up protection apparatus under the sculping screen
Including floating ball 1 and close to switch 2, the floating ball 1 is located under sculping screen in chute 6, and one end of the floating ball 1 and buoy 3 is connected,
The other end of the buoy 3 is fixedly connected after running through lower chute walls 7 with contactor 4, and the buoy 3 is arranged along horizontal plane, institute
The lower section for stating contactor 4 is equipped with close to switch 2, and contactor 4 and described close to setting interval between switch 2, described close to open
2 are closed to be connected by relay with control cabinet, to control the opening and closing of sculping screen, in the initial state, the contactor 4
It is in discrete state close to switch 2 with described, lower chute walls 7 are equipped with for the perforative through-hole of buoy 3, and the through-hole slips under
The short transverse of cell wall 7 is arranged, and the buoy 3 can move up and down in the through-hole along the short transverse of lower chute walls 7, institute
It states on the outside of lower chute walls 7 and is located at below the through-hole and be installed with pressure pin 5, the pressure pin 5 is to lift the buoy
3。
Under normal circumstances, medium is not present under sculping screen in chute 6, at this point, floating ball 1 is located at chute under the sculping screen
6 bottom, due to being self-possessed in the state naturally drooped, contactor 4 is not contacted with described close between switch 2, is approached buoy 3
Switch 2 is failure to actuate, and in the present embodiment, the contactor 4 is induction band iron.When chute 6 blocks under sculping screen, under sculping screen
When the bottom of chute 6 is full of medium, floating ball 1 floats immediately under buoyancy, drives buoy 3 to move downward around pressure pin 5, together
When, the contactor 4 is contacted with close to switch 2, is acted close to switch 2, and the relay and control cabinet connecting with close to switch 2 connect
It connects, the contact-making switch in control cabinet is controlled by relay signal and is disconnected, it is out of service to control sculping screen, to be latched higher level
Equipment prevents a large amount of medium flow fields excessive, reduces time and the manpower of processing medium flow field, reduces loss for coal mine.
The utility model is described in detail above, it is described above, only the preferred embodiment of the utility model and
, when the utility model practical range cannot be limited, i.e., all according to the made equivalent changes and modifications of the application range, it should still belong to this
In utility model covering scope.
