Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention kneads and granulates dust, sludge, slurry, etc. collected by an air pollution device, a water treatment device, etc. in a state where they are easily recycled. The present invention relates to a vibration kneading and granulating device.

[Prior art and its problems] It is common practice to knead various raw materials by using a rod or ball type kneading mill and granulate the kneaded product to obtain a product. Since the kneading of the raw materials and the granulation of the kneaded product are performed by different devices, respectively, the cost is high, and it is necessary to provide a conveying device between the kneading device and the granulating device. Therefore, there is an inconvenience that the equipment becomes large.

[Object of the Invention]

Therefore, an object of the present invention is to solve the above-mentioned inconvenience, and to make it possible to knead and granulate the raw materials with one device, thereby making the equipment compact and reducing the cost.

[Structure of Invention]

In order to achieve the above-mentioned object, the present invention mounts a cylindrical drum containing a kneading medium on an elastically-supported support base, and arranges a pair of vibrators that are synchronously rotated on both sides of the drum. A raw material supply hole is provided at the upper part of the outer periphery of one end of the drum, and a discharge port is formed at the other end. An end plate is attached with a space for dropping the kneaded material between the discharge port and the discharge port. The granulation molding cylinder for receiving the drop discharge is connected to the drum.

[Action]

When the raw material is supplied to the supply hole of the vibration kneading and granulating apparatus having the above structure and the pair of vibrators are synchronously operated, the drum vibrates circularly, and the medium contained therein vigorously vibrates and rotates inside the drum. Therefore, raw materials and media, raw materials and drums,
Media-to-media, media-to-drum impact, shear,
The raw materials are kneaded and mixed by the action of friction or the like, and the kneaded product falls into the granulation molding cylinder through the discharge port and the dropping space. Here, since the granulation molding cylinder is connected to the drum and vibrates together with the drum, the kneaded product dropped into the granulation molding cylinder is granulated, and the granulation product is discharged from the end of the molding cylinder.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in the figure, the support base 2 arranged above the base 1 is elastically supported by a plurality of springs 3 provided between the base 1 and the base 1, and the cylindrical drum 4 is mounted on the support base 2. There is. A pair of vibrators 5, 5 are provided on both sides of the drum 4.
5 is attached, and the vibrator 5 is synchronously operated via a belt transmission device or the like.

A supply cylinder 6 is connected to the outer peripheral upper part of one end of the drum 4, and the inside of the supply cylinder 6 is partitioned by a partition plate 7.
The two raw materials can be supplied separately. A discharge port 8 is provided at the other end of the drum 4, and an end plate 10 is attached to the discharge port 8 with a space 9 for dropping the kneaded material in between.

Below the falling space 9, the end of the granulation molding cylinder 11 that receives the falling objects from the space 9 faces, and the granulation molding cylinder 1
The flange 12 provided at one end is superposed on the flange 13 formed at the other end of the drum 4 and connected by means such as welding.

The granulation molding cylinder 11 may have any shape, and may have a semi-cylindrical shape or a cylindrical shape as illustrated.

Further, a kneading cylinder 14 is arranged inside the drum 4. An axial opening 15 is formed in the upper part of the outer periphery of the kneading cylinder 14.
Is provided. Further, the kneading cylinder 14 is arranged at an eccentric position with respect to the shaft center of the drum 4, and the lower portion of the outer peripheral surface thereof is supported by a block 16 provided on the lower portion of the inner peripheral surface of the drum 4 so as to be between the inner peripheral surface of the drum 4 and the block 16. A required gap 17 is provided, and both side edges of the opening 15 are engaged with protrusions 18 provided on the upper portion of the inner peripheral surface of the drum 4, and by the engagement, upward movement of the kneading cylinder 14 is prevented. Has been done. Inside the kneading cylinder 14, a medium 19 composed of a large number of rods is accommodated.

The vibrating kneading and granulating apparatus shown in the example has the above structure,
This apparatus vibrates the drum 4 by driving the vibrator 5, and in that state, the raw material is supplied from the supply cylinder 6 into the drum 4 to knead and granulate.

Now, when the pair of vibrators 5 and 5 are synchronously operated, the drum 4
Circularly vibrates, and the medium 19 contained in the kneading cylinder 14 vigorously vibrates while rotating. Therefore, when the raw material is supplied to the inside of the drum 4, the raw material and the medium 19, the raw material and the kneading cylinder 14, the medium 19 and the medium 19 and the medium 19 and the kneading cylinder 14 are subjected to the effects of impact, shear, friction and the like. Then the raw materials are kneaded. Further, since the kneading cylinder 14 vibrates violently due to the collision action of the medium 19 and the raw material, even if the raw material is a wet raw material, the raw material rarely adheres to the inner peripheral surface of the kneading cylinder 14, and However, the vibration of the kneading cylinder 14 causes a peeling action, and as a result, the wet raw material can be effectively and surely kneaded.

The kneaded material flows from the discharge port 8 at the other end of the drum 4 into the dropping space 9 and falls into the granulation molding cylinder 11. Since the granulation molding cylinder 11 is connected to the drum 4, the granulation molding cylinder 11 also vibrates in a circular manner, the kneaded product is granulated by the vibration, and discharged from the tip of the granulation molding cylinder 11. To be done.

In the case of the embodiment, the kneading cylinder 14 is provided inside the drum 4, but this may be omitted.

〔effect〕

As described above, according to the present invention, circular vibration is applied by driving the vibrator, and the granulation molding cylinder is connected to the other end of the cylindrical drum in which the medium is housed. The raw material can be kneaded and granulated by the apparatus, and the equipment can be downsized and the cost can be reduced.

Also, since the discharge port is formed at the other end of the drum and the end space is formed between the discharge port and the discharge port, the kneaded material kneaded inside the drum falls from the discharge port into the drop space. It smoothly flows and kneading and granulation can be performed efficiently.
