Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cyclone type mixer used for pretreatment of pouring construction.

[0002]

2. Description of the Related Art Conventionally, a mixer used for construction of a pouring material is a machine for rotating powders or the like of the pouring material inside the mixer by rotating a blade or a roller arranged inside the mixer. It is generally used for adding water to powder and kneading.

[0003]

In the conventional method using a mixer, when water is added to the powder of the pouring material in the mixer and kneading, it is difficult to mix uniformly, so that the kneading requires a long time. Further, there is a problem that it takes time and labor to remove the kneaded pouring material adhering to the inner wall surface of the mixer, and it takes a long time to discharge the kneaded pouring material. There was also the problem of doing. The present invention has been made to solve the above-mentioned problems, and to provide a cyclone type mixer for pretreatment of pouring material construction, which can mix, knead and discharge the pouring material in a short time and does not require human labor. ..

DISCLOSURE OF THE INVENTION The present invention is a cyclone type mixer which mixes air-casting casting material with water and separates the air and the casting material, which is tangential to the upper surface of the inverted conical body 10. At this position, a pipe 6 for transporting a pouring material around which a water ring is installed is fixed, an air cleaning device 2 is arranged on the upper part of the main body, and a vibrator 5 is arranged on the outer side of the lower inverted cone part of the main body. A cyclone type mixer for pretreatment of pouring material is characterized in that a plurality of spiral collision members 4 are provided on the inner wall portion of the inverted conical portion of the main body.

[0005]

In the present invention, first, the water sprayed from the water ring is added to the powder of the casting material that has been pneumatically transported. Inside the cyclone type mixer, the carrier air and the poured material that has been mixed with water collide with the spiral collision member and are separated. The pouring material is rapidly mixed and kneaded in the inverted conical body portion by utilizing the thixotropic effect of the pouring material by the vibration of the vibrator. Furthermore, the pouring material due to vibration,
It can be discharged quickly without adhering to the inner wall surface of the cyclone type mixer. The operation of the present invention will be described below step by step. The powder of the pouring material is pneumatically transported and is hydrated by water jetted from a water ring arranged near the cyclone type mixer. The hydrated pouring material causes a turbulent flow inside the cyclone type mixer by the spiral collision member, and is separated into carrier air and hydrated pouring material. The hydrated pouring material is mixed and kneaded by being vibrated in order to utilize the thixotropic effect of the powder, and further, the pouring material is not attached to the inner wall surface of the cyclone type mixer and is quickly discharged. The carrier air is cleaned by an air cleaning device such as a water repellent bag filter and then discharged to the outside. An example of the spiral collision member is shown in FIG. Figure 2
(A) is a case where the collision member is vertical and straight.
(B) is a case where it is inclined, and θ is 0 <θ <depending on conditions such as the shape of the inverted conical body and the properties of the casting material.
Change between 90. Although the cross-sectional shape of the spiral collision member is a triangle in FIG. 2, an appropriate shape can be selected according to various conditions. Furthermore, the length of the spiral collision member is also selected to be an appropriate length depending on the shape of the inverted conical body, the properties of the casting material, and the like.

【Example】

(1) When blast furnace tapping is carried out, the cyclone type mixer according to the present invention is hung by a cast bed crane, and the construction is carried out by moving it to a predetermined location, resulting in easy and quick construction, and high quality construction. I got a body. (2) When the blast furnace tappipe was installed, the cyclone-type mixer according to the present invention was attached to the arm tip of the hydraulic excavator car, and the result was that the bar-shaped vibrator was installed side by side.
A quick construction and a high quality construction body were obtained. In the conventional construction method, one raw material supplier, two raw material carriers, three mixer operation / carriers, one construction instructor, a total of seven were required.
When the construction is carried out using the cyclone type mixer according to the present invention, it can be constructed by one raw material supplier, one raw material transport operator, one mixer transfer carrier, one construction instructor, a total of four people,
It was labor saving for 3 people.

Besides the above-mentioned embodiments (1) and (2), there are many application examples. The effects of the present invention can be summarized as follows. Since the pouring material can be continuously supplied and the mixing and kneading can be continuously performed, the working efficiency and the mixing and kneading efficiency are improved. Since there are no rotating blades or rollers inside the cyclone type mixer, the inside of the mixer can be easily cleaned and no material is wasted. Since there are no rotating parts inside the mixer, there are few failures. Due to the simple structure of the mixer, parts can be easily replaced. It can also be designed compact. Since there are no rotary blades and rollers inside the mixer, the casting material and the fibrous material can be uniformly mixed.

[0008]

As described above, according to the present invention, the efficiency of construction, mixing and kneading is improved, and manpower can be significantly reduced.
