Description

Technical Field

[0001] The utility model belongs to the technical field of boiler slag recovery, and particularly relates to a boiler slag recovery device. Background Art

[0002] After the fuel enters the boiler and is burned, it forms slag. In order to further recycle the slag, the slag in the boiler is usually discharged, cooled, and then packaged for reuse. The existing boiler slag recovery device can meet the basic needs of cooling the slag, but the water cooling structure used does not have a stirring structure for stirring the cooling water. As a result, part of the cooling water is discharged from the cooling device without fully exerting its cooling effect, which leads to the need to replace the cooling water more frequently, which also causes a waste of cooling water.

[0003] For example, the utility model with the announcement number CN 209310011 U discloses a special boiler slag recovery device. In the technical solution of this patent, the slag inside the conveying barrel is recovered by a cold water pipe arranged on the outside of the conveying barrel with heat conductive properties. Since there is no stirring structure inside the cold water pipe, some cooling water far away from the conveying barrel cannot fully exert its cooling effect, which will increase the frequency of replacing the cooling water and cause waste of cooling water, which will bring great inconvenience to people's use. Utility Model Content

[0004] In view of this, the utility model aims to improve the deficiencies of the prior art and provide a boiler slag recovery device, which can not only meet the basic needs of slag recycling, but also stir the cooling water in the cold water structure through the stirring structure, so that the cooling effect of the cooling water can be fully exerted and better meet people's usage needs.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a boiler slag recovery device, including a base, a screw conveyor with a side wall having heat conductive properties is horizontally arranged on the top of the base through a support rod, a cooling cylinder is arranged on the outer wall of the screw conveyor, a water inlet pipe is arranged on the top of the cooling cylinder, a water outlet pipe is arranged on the bottom of the cooling cylinder, a control valve is arranged on the water outlet pipe, a temperature sensor extending to the inside of the cooling cylinder is also arranged on the side wall of the cooling cylinder, a plurality of telescopic push rods with output shafts extending to the inside of the cooling cylinder are horizontally arranged on the outer wall of the right end of the cooling cylinder, connecting rods are respectively arranged on the inner ends of the output shafts of the plurality of telescopic push rods, and a plurality of stirring blades compatible with the cooling cylinder are commonly arranged on the plurality of connecting rods.

[0006] As a further improvement of the present invention, a transparent observation window is also provided at the front end of the cooling cylinder.

[0007] As a further improvement of the present invention, a feeding auxiliary module is also provided at the feeding end of the screw conveyor.

[0008] As a further improvement of the utility model, the feeding auxiliary module includes a feed guide bucket detachably arranged at the feed end of the screw conveyor, an L-shaped mounting frame is arranged on the top of the feed guide bucket, a stirring motor is vertically arranged on the top of the mounting frame, a stirring shaft extending to the feed end of the screw conveyor is arranged at the lower end of the output shaft of the stirring motor, and stirring blades compatible with the feed guide bucket and the feed end of the screw conveyor are arranged on the stirring shaft.

[0009] As a further improvement of the utility model, a reinforcing rod is further arranged between the horizontal portion and the vertical portion of the mounting frame.

[0010] As a further improvement of the utility model, the feed guide bucket is fixedly connected with the feed end of the screw conveyor, and the side end of the feed guide bucket is also provided with a connecting cylinder fixedly connected with the feed end of the screw conveyor, and the connecting cylinder is also provided with a connecting bolt for fixing the feed end of the screw conveyor, and the feed end of the screw conveyor is provided with a threaded connection hole adapted to the connecting bolt. The connecting bolt is a hand-tightened bolt.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] Firstly, cooling water can be added to the cooling cylinder through the water inlet pipe, so as to cool the screw conveyor and the slag inside the screw conveyor until the slag is discharged through the discharge end of the screw conveyor; at the same time, the output shafts of multiple telescopic push rods can be adjusted to allow multiple connecting rods and multiple stirring blades to move back and forth laterally, so as to stir the cooling water inside the cooling cylinder, so that the temperature of the cooling water is kept balanced, thereby making full use of the cooling effect of the cooling water. When the temperature sensor finds that the temperature of the cooling water in the cooling cylinder is too high, the control valve can be opened to discharge the cooling water that can no longer exert the cooling effect out of the cooling cylinder through the discharge pipe, and then a new cooling cylinder can be added to the cooling cylinder.

[0013] Secondly, through the feed guide bucket, users can more conveniently add slag to the feed end of the screw conveyor. Through the cooperation of the stirring motor, stirring shaft and stirring blades, the slag in the feed guide bucket and the feed end of the screw conveyor can be stirred, so that the slag can enter the interior of the screw conveyor more smoothly and quickly.

[0014] Thirdly, the reinforcing rod can enhance the firmness of the mounting frame and extend the service life of the mounting frame.

[0015] Fourthly, the feed guide bucket and the feed end of the screw conveyor can be flexibly fixed by only clamping and fixing the feed guide bucket and the connecting cylinder with the inner and outer walls of the feed end of the screw conveyor respectively, and then passing the connecting bolts through the side walls of the connecting cylinder and screwing and fixing them with the threaded connecting holes.
