Description
Technical field:
A kind of screen cloth with heater applies to industries such as coal, building materials, mine, belongs to the technical field that particulate and screen cloth are separated fast.
Background technology:
Vibratory sieve is extensively to apply to coal, building materials, a kind of shaker separator optional equipment of industries such as mine.
Existing vibratory sieve is in sieving production process, and particulates such as coal dust that hygrometric state is tiny and construction material are bonded on the cold screen cloth easily, stops up sieve aperture, thereby has reduced screening efficiency.Currently used is to shake by force, mechanical system such as beats and reduces plug-hole, adopts this method effect when the material water ratio that is sized 8% is above still undesirable.
The utility model content:
The purpose of this utility model is, has proposed a kind of screen cloth with heater, and it can carry out evenly suitable heating to screen cloth, facilitates material particulate institute water content rapid evaporation.Be aided with the appropriate hammering of machinery after the heating again, the material particulate just is easy to peel off from screen cloth, just can solve the sieve aperture problem of stopping up preferably.
The screen cloth heater that the utility model proposed is characterized in that, it contains metallic sieve and heater, and described heater is a transformer, and the former limit of this transformer connects AC power, and its secondary connects two opposite side of screen cloth.
Described screen cloth is a kind of tape frame and the vibratory sieve that vibrates with framework; The secondary of described transformer is a rigid conductive body that passes transformer core, an one output connects an electric conductor, this electric conductor is connected with a limit of screen cloth by the mode of pressing, and as the part of the framework of screen cloth, its another output connects another electric conductor, this electric conductor presses connection with another relative limit of described screen cloth, and also as the part of the framework of screen cloth, limit of screen cloth and as the framework of screen cloth, its another output connects another relative limit of described screen cloth and also as the framework of screen cloth, makes screen cloth and transformer secondary form the loop.Described screen cloth can have two, described two screen clothes limit separately links to each other with an electric conductor jointly, two another relative separately limits of screen cloth connect two electric conductors that described transformer secondary is connected respectively, and two screen clothes are serially connected with in the loop of transformer secondary.
Described screen cloth has two to be positioned over the conductive support that is used for mesh support screen under two opposite side of screen cloth, and described two conductive support connect two outputs of described transformer secondary respectively.
Described heater can be the high-frequency heating circle that is positioned under the screen cloth.Described high-frequency heating circle has more than two.
Experiment showed, that the utility model can carry out uniform heating to the screen cloth in the vibration, make material particulate institute water content rapid evaporation,, reached its intended purposes screen cloth being carried out particulate is broken away from fast after machinery knocks.
Description of drawings:
Fig. 1 is the structural representation that directly send the screen cloth of electric type, and wherein 1 is the former limit of transformer, and 2 is iron core, and 3 is the transformer secondary, and 4 is screen frame, and 5 is screen cloth, 10 electric conductors for the secondary connection;
Fig. 2 be the side schematic view of double-deck mesh screen wherein 6 for lower screen, 7 is ball;
Fig. 3 is conductor rail (transformer secondary or framework) and mesh screen connecting portion structural representation, and wherein 8 is compressing member;
Fig. 4 is a support type heating net sieve structure schematic diagram, and wherein 9 are the mesh screen support;

The specific embodiment:
The vibratory sieve that vibratory sieve, the vibration sieve that existing striking mechanism is arranged, the screen cloth frame that existing screen cloth has framework to vibrate with screen cloth shakes significantly.
For the vibratory sieve of framework 4,3 with screen cloth 5 vibrations, the secondary 3 of transformer and the framework of screen cloth can be connected as a single entity, make in the loop of mesh screen 5 by framework 3,4 serial connections and transformer secondary.Seeing shown in Figure 1ly, is the form of two mesh screens serial connection, and two mesh screens are connected by framework 4 (electric conductor) jointly on one side, and another opposite side of two screen clothes connects electric conductor 10 respectively, and two outputs by electric conductor 10 connection secondary 3.When screen cloth 5 vibrations, framework vibrates together with the transformer secondary.The secondary of transformer passes iron core 2, fixedlys connected with screen frame in its two ends, and its connection layout is seen Fig. 3, and its fixed form is with bolt 8 (pressing part) guide rail 3 (transformer secondary) to be pressed to be fixed together.Guide rail (framework) vibrates with the screen cloth of vibration, avoided power electrode to be connected with screen cloth and become flexible the loose contact that causes because of screen cloth vibrates, fracture with the mechanical fatigue that causes because of the screen cloth vibration causes has solved problem from electricity to the vibration screen flexibility that send well.The former limit of transformer can be single phase ac 380V and 220V voltage, and secondary voltage can be below 35V, and transformer capacity can be designed to adjustable, with at different screen clothes.Transformer core is a silicon steel sheet.Can transfer another net 6 at screen cloth during use, put ball 7 between two layers of mesh, see Fig. 2 as knocking screen cloth usefulness.
Knock the vibration sieve of screen cloth mechanism for existing, can utilize screen cloth gripper shoe (post) 9 as conductive plate, promptly the secondary of transformer is by the gripper shoe 9 of electric conductor 10 connection screen clothes 5, as Fig. 4.In Fig. 4, secondary is a conducting ring, and 3 are enclosed within on the iron core 2.Also conductive plate can be divided into several sections that are uneven in length, the transformer secondary is changed into many enamel-covered wire grouping coileds, every group links to each other with one section conductive plate respectively, comes subregion control screen temperature with this.
For the vibratory sieve that the screen cloth frame shakes significantly, can settle high-frequency heating circle 11 5 times at screen cloth, metallic sieve produces eddy current heating screen cloth under high-frequency electromagnetic induction.The high-frequency heating circle maintains static under screen cloth, by magnetic field energy is passed to screen cloth.The high-frequency heating circle can be placed a plurality of, so that evenly heating.This Electric heating avoided as in the scheme one because of mechanical connection shakes the restriction of amplitude to the screen cloth frame, but it is higher to make maintenance cost.
