Abstract

The utility model discloses a conveying appliance for tar sinter, comprising a hopper with an upper part which is an open feed port and a lower part which is a discharge port. The conveying appliance for tar sinter is characterized in that a heating jacket with an inlet and an outlet is arranged out of the hopper, and an axial spiral thruster is arranged in the hopper. The conveying appliance for tar sinter solves the problems that the prior art can not ensure tar sinter and coal can be mixed fully and the mix of tar sinter and coal are easy to agglomerate, block and pollute conveying belt. Tar sinter is heated before conveying, the viscosity of tar sinter is decreased, and the flowability of tar sinter is increased; via squeezing by the spiral thruster, tar sinter can be evenly distributed on matching coal on conveying belt in material unloading process in order to evenly mix with matching coal without polluting conveying belt, labor intensity is effectively reduced for workers, and the normal production of coke oven is ensured.

Description

A kind of feedway of tar slag

Technical field

The utility model relates to a kind of feedway, especially a kind of feedway of carrying fusion that materials such as tar slag are arranged.

Background technology

Tar slag is the bits of separating from coal tar naphtha.It contains the material of many recyclable utilizations, and as coal tar naphtha, coal dust, coke powder etc., old friends are reluctant to abandon it, but it is incorporated into together coking in the coal.Because the viscosity of tar slag is bigger, not only self easily forms bulk, be difficult to mix with coal, and load transfer device can be damaged and pollute to the tar slag of bulk also, the obstruction that also causes coal tower tiger mouth simultaneously and add the coal car coal filling hole had both increased operator's work capacity, influenced coke oven production again, therefore, be necessary prior art is improved.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of prior art, and a kind of difficult obstruction, prevented from caking, blanking feedway smoothly is provided.

The utility model is realized by following technical proposal: a kind of feedway of tar slag, comprise that its top is that charging is uncovered, and the bottom is the hopper of discharging opening, it is characterized in that hopper is provided with the heating jacket of bringing into, exporting outward, is provided with the axial screw propelling unit in the hopper.

Import and export on the described heating jacket is separately positioned on the upper and lower of heating jacket, so that steam or hot water or etc. heating medium enter in the cover, carry out interchange of heat with the tar slag in the hopper after, flow out by outlet again, thereby reduce the viscosity of tar slag, increase its flowing power.

The rotating shaft of described spiral propeller is located on the hopper central axis, its upper end links to each other with machine shaft by bearing, umbrella tooth, so that under driven by motor, rotate, its lower end extends to the discharging opening of hopper bottom, blade is arranged on the middle and lower part of rotating shaft, and blade diameter diminishes from top to bottom gradually, so that the material in the hopper is pushed away.

The utility model compared with prior art has following advantage and effect: pass through such scheme, solved prior art and can't guarantee that tar slag fully mixes with coal, easily lump, easily stop up, easily pollute problems such as load-transfer device, make tar slag before conveying, finish heating, both reduced its viscosity, increase its flowing power again, extruding by spiral propeller again, guarantee that tar slag can be evenly distributed on the mixed coal of load-transfer device in the blanking process, make it to mix with mixed coal, and do not pollute load-transfer device, effectively reduce working strength of workers, guarantee the ordinary production of coke oven.

Description of drawings

Fig. 1 is the installation site figure of the utility model;

Fig. 2 is the structural representation of the utility model.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing is described further the utility model.

Among the figure, 1 is hand barrow, being used for pouring tar slag into

hopper

3,5 is belt conveyor, places the below of hopper 3, so that in the process of carrying mixed coal, the interior tar slag of hopper is evenly distributed on delivers to coke oven on the mixed coal together, 3 is hopper, and its upper end is charging uncovered 2, the lower end is a discharging opening 4,6 is the umbrella tooth that links to each other with motor, is installed in rotating shaft 9 upper ends of spiral propeller, so that under driven by motor, by umbrella tooth 6 rotating shaft 9 is rotated thereupon, rotating shaft 9 places on the hopper central axis, and is fixed on by bearing and bearing seat 7 on the strut bar 8 at hopper 3 tops, and 10 is another bearing and the bearing seat of fixed pedestal rotating shaft 9, it is installed on the interior support 16 of hopper, 11 is drive coupling, and 12 is the blade of spiral propeller, and its diameter diminishes from top to bottom gradually, so that pressing materials, 14 is heating jacket, and along the outer wall setting of hopper 3, its underpart is provided with heating medium flow export 13, top is provided with heating medium inflow entrance 15, so that the material in the hopper is heated.

Claims

1, a kind of feedway of tar slag comprises that its top is that charging is uncovered, and the bottom is the hopper of discharging opening, it is characterized in that hopper is provided with the heating jacket of bringing into, exporting outward, is provided with the axial screw propelling unit in the hopper.

2, feedway according to claim 1 is characterized in that the import and export on the described heating jacket is separately positioned on the upper and lower of heating jacket.

3, feedway according to claim 1, the rotating shaft that it is characterized in that described spiral propeller is located on the hopper central axis, its upper end links to each other with machine shaft by bearing, umbrella tooth, the lower end extends to the discharging opening of hopper bottom, blade is arranged on the middle and lower part of rotating shaft, and blade diameter diminishes from top to bottom gradually.
