Description
Technical field
The utility model relates to mine equipment equipment technical field, particularly a kind of colliery thermal mineral vibrating screen.
Background technology
The thermal mineral vibrating screen used now, vibrator is generally all positioned at the top of sieve plate, but the temperature of the material sieved is general all more than 800 DEG C, under vibrator is in the working environment of high temperature for a long time, so just on causing direct impact the service life of vibrator, if improve vibrator height residing on screening plant, then the intensity of whole screening plant and design are had higher requirement, add the production cost of equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of colliery thermal mineral vibrating screen, solves under vibrator is in the working environment of high temperature for a long time, on the problem causing directly impact the service life of vibrator.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of colliery thermal mineral vibrating screen, comprises base, vibrator, screen box, sieve plate, motor, is provided with sieve plate in described screen box, be provided with two axles above sieve plate, be provided with fixed head between described two axles, and fixed head strengthens the structural strength of screen box; Described screen box is connected with exciting vibration spring by jockey, described jockey is made up of iron plate and bolt, described exciting vibration spring one side-lower is provided with spring fastening, casing is provided with below exciting vibration spring opposite side, two vibrators are provided with in described casing, described vibrator is connected with motor by belt, is provided with thermal insulation board between described vibrator and sieve plate, is provided with base below described spring fastening and casing.
Preferably, described casing outside is provided with thermal insulation board, and casing is provided with ventilating opening, and in casing, vibrator place is provided with blower fan, and blower fan dispels the heat to vibrator, motor, ensures that vibrator, motor run well, extends the service life of vibrator in thermal mineral vibrating screen.
The utility model compared with prior art beneficial effect shows: 1) the utility model is rational in infrastructure, practical, and the temperatures involved can effectively avoiding vibrator to be brought by high-temperature material, extends the service life of vibrator in thermal mineral vibrating screen; 2) casing outside is provided with thermal insulation board, and in casing, vibrator place is provided with blower fan, when vibrator is heat insulation, dispels the heat again to vibrator, ensures that vibrator runs well, ensures the normal operation of coal production line.

Detailed description of the invention
For convenience of the understanding of the art personnel, below in conjunction with accompanying drawing 1-2, the technical solution of the utility model is illustrated further.
A kind of colliery thermal mineral vibrating screen, comprise base 1, vibrator 9, screen box 4, sieve plate 6, motor 10, in described screen box 4, be provided with sieve plate 6, above sieve plate 6, be provided with two axles 5, be provided with fixed head 12 between described two axles 5, fixed head 12 strengthens the structural strength of screen box 4; Described screen box 4 is connected with exciting vibration spring 3 by jockey 7, described jockey 7 is made up of iron plate and bolt, described exciting vibration spring 3 one side-lower is provided with spring fastening 2, casing 8 is provided with below exciting vibration spring 3 opposite side, two vibrators 9 are provided with in described casing 8, described vibrator 9 is connected with motor 10 by belt, is provided with thermal insulation board 11 between described vibrator 9 and sieve plate 6, is provided with base 1 below described spring fastening 2 and casing 8.
Described casing 8 outside is provided with thermal insulation board 11, and casing 8 is provided with ventilating opening, and in casing 8, vibrator place is provided with blower fan, and blower fan dispels the heat to vibrator, motor, ensures that vibrator, motor run well, extends the service life of vibrator in thermal mineral vibrating screen.
A kind of colliery thermal mineral vibrating screen, during work: electric machine rotation drives vibrator work, vibrator work drives the upper and lower strenuous exercise of exciting vibration spring, exciting vibration spring motion drives screen box motion, and screen box motion drives the coal cinder motion in screen box, and thermal insulation board stops the heat transmitted, prevent heat from passing to vibrator and motor, blower fan work in casing, leaves the heat in casing, avoids vibrator and motor to burn out or affects its life-span.
Above content is only to structure example of the present utility model and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
