Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for homogeneously FC-mixing granular materials of varying quality, particle size, etc., and particularly relates to an apparatus for mixing large-capacity granules.

Traditionally, when it comes to grains such as rice and wheat, even though they are the same variety, the maturity, moisture content, and grain size vary depending on the differences in the four-cropped fields, the location, the weather at 60 pm, and the differences in the breeder. There are also differences in diameter. It is desirable for tt rice to be as homogeneous as possible as a control rice, and the current situation is that it is mixed and packed in bags as much as possible. In addition, synthetic granules are used in feed.

It is often mixed with natural grains and sold in single bags, and from the standpoint of guaranteeing uniform quality as a product, it is hoped that a device that can uniformly mix large amounts of granules will be developed. ing.

A device for mixing this type of granular material was already developed in a patent application filed in 1983.
-110189 and Japanese Patent Application No. 56-017814, it has achieved its purpose as a no-no-tsute type mixing device.

However, the maximum capacity of this type of Nototsuchi-type mixing device is about 2 tons for grains, for example, and if the container is made larger than this, the power to drive it is extremely large, and the noise and vibration are also large. This deteriorates the working environment and also becomes a source of pollution to the surrounding area. However, in reality, the KFi used to mix grains etc. is often several to several tens of times larger than the capacity of the container of the # mixing device, and it is not possible to mix such large amounts of granular materials with conventional equipment. .

The purpose of this invention is to improve the shortcomings of the conventional device and dramatically increase the uniform mixing ability of IIT from several times to several tens of times compared to the conventional device by adding incidental equipment to the conventional device. It is something to do.

In this invention, a receiving tank having a vertical axis is provided above the upper supply port of a non-punch type granular mixing device, and this tank is radially arranged into several independent compartments by a constant number of partition walls. The capacity of the round can compartment is made equal to the capacity of the granular material mixing device, and the granular material is rotated about the axis of the tank above the receiving tank to mix one granular material into the tank. A rotary shaker to be introduced into the compartment group is installed in the machine frame, and an opening/closing gate is provided independently at the lower end of each 1L compartment, and below these several opening/closing gates, the granules are fed into the granular material mixing device. This is a granular material mixing device with a dynamic lambda tank, characterized in that a common hopper is provided to guide the granules.

The present invention will now be described based on a first exemplary embodiment shown in the drawings.

In the figure, the figure shows a granular material mixing device of the Nonotsu type, an example of which is the vibrating type shown in Figures 1 to 4.

In the figure, numeral 10 is a seed-shaped mixing container with a rMv shape;
The inclined side 1111 has a symmetrical inclination angle of about 15° with respect to the vertical line, and the valley at the bottom is formed by the elongated discharge port 12.
It becomes. 13 is a porous diaphragm, and the inclination @

degree) 't-provided and synthesized! to the mixing container IO via an elastic member 17 such as a rubber band.

It is provided so as to be able to vibrate freely in the length direction of the discharge port 12. In place of the elastic member, the porous diaphragm 13 may be provided so as to be slidable or swingable in the horizontal direction with respect to the mixing container IO.

The diameter of the holes 14 on the entire surface of the porous diaphragm 13 is usually 5 to 20 mm.
Holes as large as 300mm are drilled at a pitch of 30 to 50m,
However, depending on the particle size and shape of the granules to be mixed, the above values may be exceeded.

For example, in the case of rice, the diameter of the hole 14 is preferably about 10 times the particle size of the granular material. The shape of the above-mentioned porous diaphragm 13 is as shown in FIGS. 3 and 4.
It can be folded into a letter shape, or it can be made by connecting two V-shaped books together. The bottom 8 (116Fi) of the porous diaphragm 13
The flat surfaces (see Figure 3) are either folded together or slightly folded upward (see Figure 2).

(See Figure 4).

A first vibration device 118a that causes the vibration plate 13' to vibrate.
As shown in the figure, it is fixed to a mixing container 10, and its vibrator is connected to a porous diaphragm 13.

If such a vibrating device 18 is used, two or more types of granular materials can be mixed in the upper feeding chamber 1919 of the mixing container 10.

Pour the liquid into the porous diaphragm 13 until it reaches its full capacity.

Therefore, the amplitude l is generated by the porous diaphragm 13t and the vibration device 18.
When vibrating at a speed of 120 to 90,051 cm and a vibration cycle of 200 to 3,600 c/sξC, the particulate matter corresponding to the 6 holes of the porous diaphragm 13 is trapped in the gap between the porous diaphragm 13 and the slope w11. , flows down along the slope 1111. At this time.

It falls regardless of the difference in particulate matter or the vertical position of the hole.

Transport gold particles. The capacity of the above-mentioned mixing device is for mixing grains, and the maximum capacity is limited to 2) the degree of grain mixing, taking into consideration economic conditions, working environment, vibration limits, etc. Therefore, it goes without saying that technically it is possible to manufacture products on a larger scale than this.

The mixing device that can be used in the present invention may be one in which a closed container rotates, or one in which stirring blades rotate in a tank, and is not particularly limited to this type.

In Figures 5 to 7, B is a receiving tank installed above and separately from the supply port 19 for the mixing device, and its total volume is an integer multiple of the capacity of the mixing device. It's Toshide. In the illustrated one, the receiving tank B is a rigid cylindrical tank having an axis in the vertical direction, and the distance W21 provided in the radial direction is several 1! ! It is divided into compartments 22 (six in the figure), and the volume of each compartment 22 is made to correspond to the volume that can be mixed at one time by the mixing device, for example. If the capacity of the mixing device is 2 tons, then the capacity of one compartment 22 is also 2 tons. The number of compartments ranges from 6 to 1, depending on the overall size K of the receiving tank B.
Usually around 6 pieces.

Not limited to this number, each compartment 2
2, each opening/closing gate 23 is provided at the bottom to open and close independently, and is supported by the machine frame 25, which is selectively opened and closed by a solenoid or a pneumatic cylinder 24. In the case where it is directly supported on the load cell type scale, the main hand of the balance - 1 serves as a kind of measuring container (Honnozoichi scale), and 2 is installed at the bottom of the receiving tank B. A repeater is used to uniformly distribute 1% granules and uniform granules into each compartment 22 via a rotary shooter 28 that rotates around the axis of the receiving #H. 29 is a receiving part of J Kerato elevator 0.

In this invention configured as described above, for example, when mixing two or more types of granules, first rotate the rotary shooter 28f to its axis 1ff15 at an appropriate speed, and When all the opening/closing gates 23 are closed and the first granular material is put into the receiving section 29, each granular material is lifted up one by one by the Nogut elevator OK and supplied to the rotating rotary chute 28, and these granular materials are The rotating chute 28 sequentially distributes the first granules to each compartment 22 so that an equal amount of the first granules remains in each compartment 22 .

Next, a second particulate material is supplied in the same manner as before, and a second particulate material is supplied to each compartment 22.
Dispense a large amount of each onto the first granules inside.

Therefore, one compartment 2 of the several compartments 22
Open the opening/closing gate 23 of No. 2, and open the entire section 22 through the common armpit 27 at the bottom.

Pour into mixing device A.

Next, the mixing device 1At is activated to mix the two types of granules.In the mixing device shown in the example, the porous diaphragm 13
This is done by vibrating.

When the two types of granules in the mixing device A are mixed and discharged from the discharge port 11 and transported to the 7 pumper 20, the opening/closing gate 23 of the primary compartment 22 is opened; The same operations as described above are carried out, and the following - similar operations are carried out for each compartment 22 until all the particles in all the compartments 220 are discharged.

In the above example, we explained that two types of granules are mixed, but if it is also possible to mix three or more types of granules, it is necessary to know the weight of each granule. can.

In the apparatus of the present invention configured as described above, the capacity of the single-sided mixer is relatively small, and even if the total volume of granules to be mixed is several times that amount, it is difficult to mix. If the total volume of the several types of particulate matter is less than the volume of the receiving tank, all of it will be absorbed into each compartment 22 of the receiving tank.
These are distributed in the same ratio to each phase of each compartment.
/”-27 to ensure that it is supplied to the mixing device A,
Because they are mixed sequentially, all the granules can be mixed evenly and softly.1 For example, it is possible to homogenize the entire amount of rice, wheat, etc. harvested on a large farm, or to collect the grains from several small-scale farmers and collect them. It becomes possible to uniformly mix rice, wheat, etc.

In the case of a sieving machine in which the receiving tank B is supported on the machine frame 25 via a weighing device 26t, the amount of rice being received at a rice center etc. can be directly determined using this weighing device, and the conventional As such, there is no need to weigh in advance using a weighing device such as a special hopper scale. Therefore, there is no need for a conventionally known hompa scale or means for transporting it there.

The total volume of the granules to be mixed brought into the receiving tank B
If the volume exceeds the volume, measure the weight of each of the different types of granules to be mixed in advance, and calculate the ratio so that the ratio of the granules to be mixed is constant.
After mixing everything with the mixing device, the receiving tank BK can be supplied at the same ratio for the second and subsequent times, so it is possible to mix the volume exceeding the receiving tank Bt. If this is the case, you can know the amount of granules being thrown into tank B on the receiving day, so when the predetermined amount is reached, stop the Nonoket conveyor O1 and close the gate attached to the rotary chute 28. It's very convenient.

The material mixed in the present invention can be used not only for grains such as rice and wheat, but also for granules such as soybeans, horse maize, and other synthetic feeds, fertilizers, and other mixing devices.
