Description

A kind of sludge drying treatment equipment

technical field

The utility model relates to sludge treatment equipment, in particular to a sludge drying treatment equipment.

Background technique

Dryer is a mechanical device that uses thermal energy to reduce the moisture content of materials, and is used to dry objects. In the harmless treatment of pollutants (such as sludge, etc.), it is usually necessary to dry the pollutants first to reduce the moisture content in the pollutants to a certain extent, and then incinerate the pollutants. In order to finally realize the harmlessness of pollutants.

The Chinese patent "direct heating dryer" with the notification number CN205919635U discloses a direct heating dryer, which includes a rotary drying furnace, a feeding mechanism, a hot air generator, and a stirring device. When the sludge to be dried enters through the feeding mechanism, it is in contact with the heat generated in the hot air generator to achieve preliminary dehydration and drying, and then it is dried again in the rotary drying furnace, and finally the sludge is dried.

When the sludge enters the drum in the rotary drying furnace, the sludge is in the form of lumps so that when heat exchange occurs with the hot air, only the surface can be dried quickly, and the inside still needs to be stirred and crushed before it can be dried, resulting in the need for the drum to The longer the axis length is designed to ensure that the sludge can be completely dried, and the farther the drum is from the air outlet, the lower the hot air temperature will be and the worse the drying effect will be.

Utility model content

The purpose of the utility model is to provide a sludge drying treatment equipment, which has the effect that the sludge can be fully dried at the position where the hot air temperature is the highest.

The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a sludge drying treatment equipment, comprising a feeder, a drum, a hot air generator connected to one end of the drum, the feeder It includes a material storage box, a screw conveyor with two ends connected to the material storage box and the upper end of the roller, and the roller is provided with a filter plate with a plurality of through holes at the connection with the screw conveyor parts; the filter plate is located above the connection between the hot wind generator and the drum.

By adopting the above technical solution, the sludge is stored on the feeder, and then the sludge is transferred to the side of the drum through the screw conveyor. There is a filter plate room between the screw conveying part and the drum, so that with the transfer of the screw conveying part, the pressure of the sludge on the filter plate is increasing, so that the through hole on the filter plate can be passed through, so that Regardless of whether it is lumpy or granular sludge, the sludge can only be made into strips from the through hole through the limit setting of the through hole, so that the volume of the sludge is small when it enters the drum. On the other hand, the filter plate is set above the connection between the hot air generator and the drum, so when the sludge falls to the lower end of the drum due to gravity, it can enter the hot air outlet at the first time, and because the falling sludge is strip-shaped , is small in size and thus dries quickly when dropped. Compared with the blocky sludge in the prior art, the inside of the strip-shaped sludge can also be dried quickly in a short time, so it is no longer necessary to use a drum with a long axis to fully dry the sludge, and the volumetric sludge can be used Smaller drum; on the other hand, since the sludge can contact the hot air when the temperature of the air outlet end of the hot air generator is the highest, the heat of the hot air can be utilized to the greatest extent.

The utility model is further configured as follows: the filter plate includes a feed pipe and a filter element placed in the feed pipe; the upper end of the feed pipe is connected with the screw conveyor, and the feed pipe The lower end is connected with the roller.

By adopting the above technical solution, when the sludge is discharged from the screw conveying part, it enters into the feeding pipe, and then is forced to pass through the filter part, and finally enters into the drum, completing the transformation from block to strip.

The utility model is further set as follows: a positioning ring is arranged inside the feeding pipe; the filter element includes a mounting ring that can be fixed on the positioning ring, and a plurality of The discharge plate of the through hole.

The utility model is further set as follows: the positioning ring is L-shaped, the lower end of the positioning ring is welded to the inner wall of the feed pipe, the installation ring is L-shaped, and the side plate of the installation ring is inserted into the between the positioning ring and the inner wall of the feed pipe.

By adopting the above technical scheme, the installation ring on the filter element is fastened to the positioning ring on the inner wall of the feed pipe to achieve positioning, and at the same time, the replacement and maintenance of the installation ring and the feed pipe can be realized, only the entire feed pipe needs to be removed Finally, replace the discharge plate with a different aperture.

The utility model is further configured as follows: the two ends of the feed pipe are connected to the screw conveying member and the roller through flanges.

By adopting the above technical solution, the flange connection makes it easier to disassemble and assemble with the screw conveying member and the drum.

The utility model is further configured as follows: one side of the drum is provided with an air inlet, and the hot air generator includes an air inlet cover with a diameter gradually increasing, and the air inlet cover is installed on the air inlet.

By adopting the above technical solution, after the diameter of the air inlet hood provided on the hot air generator is gradually increased, the range of the hot air outlet can be increased, and the wind speed can be slowed down at the same time, thereby increasing the contact time with the sludge and accelerating the hot air drying efficiency.

A further configuration of the present invention is: further comprising a discharge pipe connected to the other end of the drum.

A further configuration of the present invention is: a centrifugal fan is connected between the discharge pipe and the hot air generator.

By adopting the above technical scheme, the dried sludge is discharged from the discharge pipe, and at the same time, a centrifugal fan is connected between the discharge pipe and the hot air generator, and the excess heat is distributed from the rear end of the drum through the centrifugal fan and enters the hot air again. On the generator, it can be reused.

In summary, the utility model has the following beneficial effects: by changing the sludge inlet to the upper end of the air outlet on the hot air generator, and at the same time setting the sludge in a strip shape through the filter plate, it can fully interact with the hot air to the greatest extent. reaction, shorten the sludge drying time, and improve the working efficiency of the equipment.
