The present invention relates to a slurry dryer, and more particularly, a wet raw material in a slurry state containing a large amount of water and a dry raw material in a powder state may be used alone or in combination. Particularly, a wet raw material such as a slurry may be used as a powder. The present invention relates to a powder raw material mixed slurry dryer, which is mixed with a dry raw material, solidified (lumped), and then processed into a powder of fine particles or fine powder by pulverization, drying and classification.

In general, various industrial powders used as organic chemicals, inorganic chemicals, pharmaceuticals, foods, ceramics, and pigments are supplied with a wet slurry or cake-based wet raw material according to the manufacturing process. It is produced as a powder in a dried state by processing.

However, conventionally, in the processing of powder raw materials used in each industrial field, when a dry powder and a wet material in a slurry state containing a large amount of water are used in combination, a dehydration effect can be naturally obtained without a separate dehydration process. Although drying is possible, all commercially available drying units are configured to process slurry or cake-like liquid raw materials separately in each dedicated dryer, and there is no dryer to smoothly process them in one dryer. There is a problem in that the operating efficiency of the device is poor, such as the raw material is fixed to the inner wall of the dryer, the coagulation phenomenon between the feedstock or the drying is not made properly, which makes it difficult to apply a wide range of devices.

The present invention was created in view of the above problems, and its purpose is to solidify (lump) by mixing a certain amount of powder drying raw material with a wet raw material such as slurry containing a large amount of water after This is achieved by the continuous process of disintegration, drying and classification, so that the wet material can be powdered more efficiently, and the wet material adheres to the interior wall of the drying chamber and wet material It is to provide a powder raw material slurry dryer to improve the processability of the powder to prevent the cohesion of the liver.

In addition, the present invention eliminates the necessity of forcibly adjusting the concentration of the raw material, enables the particle size to be controlled by itself, and enables the wide application of the device, as well as improving the operating efficiency of the device. It is to provide a mixed slurry dryer.

The present invention for achieving the above object is a powder classifier having a slurry mass crusher having a rotary blade that is rotationally driven by a motor in the lower side of the chamber, and a classification member having a classification member that is rotationally driven by the motor in the upper side of the chamber A drying chamber equipped with a machine; A slurry supply unit for injecting slurry into the drying chamber by driving a slurry supply pump through a supply pipe from a slurry storage tank storing a slurry of wet material; A hot air supply unit for generating hot air for drying the raw material and allowing the hot air to be moved and supplied from the lower side to the upper side of the drying chamber; A powder raw material supply unit for supplying a powder raw material for mixing with a slurry which is a wet raw material to a drying chamber; It is characterized in that it comprises a dust collector for solidifying in the drying chamber, the dust collecting treatment of the processed powder which is pulverized, dried and classified and moved to the upper side of the drying chamber.

At this time, the upper inner surface of the chamber is arranged at regular intervals along its circumference so that a plurality of vertical plates protruding inwardly are provided integrally.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

1 is an overall configuration diagram showing a powder raw material mixed slurry dryer according to the present invention, Figure 2 is a detailed view of the main part of the present invention.

1 and 2, the powder raw material mixed slurry dryer according to the present invention has a drying chamber 10, a slurry supply unit 20, a hot air supply unit 30, a powder raw material supply unit, which is a configuration of the chamber 11. 40 and the dust collecting part 50.

The drying chamber 10 is provided with a slurry mass crusher 60 having a rotary blade 62 which is rotationally driven by a motor 61 in the lower side of the chamber 11 to disintegrate the solidified (lump) slurry. In order to classify the workpiece to be powdered, a powder classifier 70 having a classifying member 72 which is rotationally driven by the motor 71 is installed above the inside of the chamber 11.

At this time, the upper inner surface of the chamber 11 is provided with a plurality of vertical plates 12 of rectangular structure which are arranged at regular intervals along the circumference and protrude inwardly.

The lower side of the drying chamber 10 is provided with a hot air inlet 13 for the introduction of hot air, the upper side of the drying chamber 10 is provided with an outlet 14 for discharging the processed powder to the outside.

The slurry supply unit 20 is configured to inject the slurry into the drying chamber 10 through the supply pipe 23 from the slurry storage tank 21 in which the slurry, which is a wet raw material, is stored by driving the slurry supply pump 22. .

In this case, an injection nozzle (not shown) may be disposed in the drying chamber 10, and the slurry may be sprayed into the drying chamber by being connected to the supply pipe 23.

Here, the slurry will be used as a generic term for all raw materials that need to be powdered in a wet state containing a large amount of moisture.

The hot air supply unit 30 is a hot air pipe 31 connected to the hot air inlet 13 of the drying chamber 10, a hot air path 32 connected to the hot air pipe 31 to generate hot air, and the hot air path It is composed of a blowing fan 33 for blowing the hot air generated in the (32) to move from the lower side of the drying chamber 10 to the upper side through the hot air pipe (31).

The powder raw material supply unit 40 is a hopper 41 in which the powder raw material is stored, a supply pipe 42 connected to the lower side of the hopper 41 and connected to the drying chamber 10, and in the supply pipe 42. It is composed of a conveying screw 43 installed and conveyed raw material supplied from the hopper 41 into the drying chamber (10).

The dust collecting unit 50 is a powder conveying pipe 51 connected to the vent hole 14 provided on the upper side of the drying chamber 10, and a dust collector 52 for collecting the processed powder conveyed from the powder conveying pipe 51 and In addition, the dust collector 52 is composed of a rotary valve 53 for extracting the processed powder which is located in the lower side and the exhaust fan 54 for discharging the exhaust gas passed through the dust collector 52.

At this time, the dust collector 52 may be used individually or mixed bag filter or cyclone.

The powder raw material mixed slurry dryer according to the present invention having such a configuration is wet raw material and powder through the slurry supply unit 20 or the powder raw material supply unit 40 in a state in which hot air is supplied to the drying chamber 10 through the hot air supply unit 30. Raw materials (dry raw materials) are simultaneously supplied to the drying chamber 10.

Here, the hot air is introduced into the interior of the drying chamber 10 at high speed through the hot air inlet 13 from the lower side of the drying chamber 10 and swirled to form a flow upward.

At this time, the slurry as the wet raw material introduced into the drying chamber 10 has a large amount of water, so that the slurry falls to the lower side of the drying chamber or flows downward through the inner wall. It is mixed to become a water-containing mass (solidification), and the wet mass raw material is pulverized by colliding with the rotating blade 62 and the swirling hot air of the slurry mass crusher 60 which rotates at high speed, and becomes small particles (grains). As the evaporation surface area is maximized, the powder becomes more and more finely powdered, and the powder which is finely powdered at the same time as the hot air flows is transferred to the upper side of the drying chamber 10 and dried.

As the fine powder conveyed to the upper part while being dried is bumped into the vertical plate 12 which protrudes on the upper side of the inner wall while being conveyed upward, some unprocessed granules which are not finely powdered are crushed again, and at the same time, larger particles As the flow rate of the hot wind temporarily decreases by the direct plate 12, the lower plate is lowered and re-crushed to the lower disintegration zone, and the drying and raising are repeatedly performed. Some finely divided powder in this process helps to solidify (agglomeration) of the slurry which is a wet raw material continuously added so that the mass can be disintegrated by the crusher 60.

Particles that need to be classified among the finely divided powders transferred to the uppermost side of the drying chamber 10 are installed under the air outlet 14 of the drying chamber 10 again through the powder classifier 70 of the classification member 72 which is driven to rotate. Once separated, it is lowered back to the lower side of the drying chamber 10 by the rotational force of the classification member 72 to perform reprinting, drying and ascension. In this process, the finely divided powder also helps to agglomerate the continuously introduced slurry so that the agglomerates can be disintegrated and powdered by the crusher 60.

The processed powder of very light fine powder passing through the powder classifier 70 flows into the powder conveying pipe 51 through the vent hole 14 of the drying chamber 10 by the flow of hot air, and is collected by the dust collector 52. Has been processed.

Accordingly, the present invention solidifies the wet raw material in the drying chamber 10, and then disintegrates and re-crushs the drying and the ascending movement in a continuous process or repeatedly, and finally classifies again, so that the wet raw material is dried in the drying chamber 10. It is possible to prevent the phenomenon of sticking to the inner wall of the product, to eliminate the phenomenon of aggregation between the raw materials and to have the usefulness to continuously produce a dry powder processed into particles of the required size.

In addition, the present invention does not need to adjust the concentration of wet raw materials in advance, eliminating the dehydration process and the waste water treatment process, and thus the particle size can be controlled, the drying time of the material sensitive to the heat in the drying chamber of the raw material is also short It is also possible to efficiently perform the manufacturing process of products such as organic chemistry, inorganic chemistry, ceramics, pharmaceuticals, food, dyes and pigments.

Furthermore, since the process of solidifying and pulverizing, drying, and classifying continuously and simultaneously in the drying chamber 10 is not only useful for separately processing wet raw materials in the form of slurry or cake, the mixed use of these wet raw materials Of course, it is also useful for mixing and using powder raw materials.

As described above, according to the powder raw material mixed slurry dryer according to the present invention, after solidifying wet raw materials such as slurry, pulverization, drying and classification are performed in a continuous process. At the same time, the process is repeated according to the particle size, so that the wet material having a moisture content on the inner wall of the drying chamber can be prevented, as well as the cohesion between the wet materials can be prevented, thereby improving the processability of the powder. Not only do not need to forcely adjust the concentration of the wet material in advance by using the dehydration device, but also the particle size can be adjusted by itself, thereby increasing the operational efficiency of the device.

In addition, it provides the usefulness of individually using wet raw materials such as slurry containing moisture or mixing wet raw materials individually, and enables wide use of the apparatus, and also enables organic chemistry through automated production of powder by the apparatus.
