[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for charging a precoat material into a filter dust collector such as a bag filter.

[0002]

2. Description of the Related Art Conventionally, a pre-coating material feeding device for feeding a pre-coating material into a filter dust collector such as a bag filter is provided with a countermeasure against a bridge generated in the tank separately from a mechanism for discharging the pre-coating material in the tank from an inlet. Although a vibration device such as a vibrator is attached as a mechanism, a mechanism that discharges the pre-coat material in the tank from the input port and a vibration device as a bridge countermeasure are usually activated by different power sources, In addition to the increase in the size of the apparatus, there is a problem that the running cost as well as the initial cost increases.

[0003]

The problem to be solved by the present invention is to solve the above-mentioned problems, to enable the precoat material to be accurately and easily put into the filter dust collector, and to reduce the size of the apparatus. An object of the present invention is to provide an economical apparatus for feeding a precoat material that can reduce both initial cost and running cost.

[0004]

SUMMARY OF THE INVENTION According to the present invention, there is provided a pre-coating material charging apparatus which solves the above-described problems. A plate is provided, and an air blowing port for discharging pre-coat material in the tank from an input port while blowing air toward the lower back surface of the inclined diaphragm to vibrate the inclined diaphragm is provided. .

[0005]

In the precoat material charging device, the charging port is connected to a filter dust collector such as a bag filter in the same manner as a conventional device of this type, and the inclined diaphragm in the precoat material filling tank containing the precoat material is stored. When air is blown from the air inlet toward the lower back surface, the air causes the inclined diaphragm to vibrate, causing the pre-coated material in the tank to flow down properly to the inlet, and discharging the pre-coated material from the inlet. And put into the filter dust collector.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail based on the illustrated embodiment. Reference numeral 1 denotes an inclined diaphragm provided in a precoat material filling tank 3 having an inlet 4 on the front surface of the lower end so that the lower end thereof faces the inlet 4. As shown in FIG. 2, the inclined diaphragm 1 has a lower edge formed in a sawtooth shape and is stretched obliquely downward from the rear middle in the precoat material filling tank 3 toward the inlet 4. The hopper-shaped bottom of the filling tank 3 is formed. Then, the inclined diaphragm 1 as vibration by the air blown from the bottom, outer to those made of flexible material to the extent that is vibrated by air blowing the main plate portion 5, as shown, not shown May be arbitrary such that both sides of the inclined diaphragm 1 are supported by the eaves of the inner wall of the precoat material filling tank 3 (not shown), and the upper end of the rear portion is pivoted by a pivot to be pivoted about the pivot. Incidentally, it inlet 4, as shown in FIG. 2, a plurality of divided openings Ru Citea to that laterally continuous with irregularities 2 formed on the lower edge of the front plate of the pre-coating material filling tank 3. Reference numeral 6 denotes an air blow port provided on the rear surface of the pre-coat material filling tank 3. The air blow port 6 is connected to a blower or the like and air is directed toward the lower back surface of the inclined diaphragm 1 in the pre-coat material fill tank 3. And the inclined diaphragm 1 is vibrated by the air blowing, and the pre-coat material stored in the pre-coat material filling tank 3 is blown out from the charging port 4 by the air flow toward the charging port 4. Reference numeral 7 in the figure denotes a rectifying cover for preventing the precoat material blown out from the inlet 4 from scattering to the upper part.

[0007] In the apparatus constructed as described above, the input port 4 is connected to a filter dust collector such as a bag filter, and the pre-coated material is stored in the pre-coated material filling tank 3, and the pre-coated material is put on the filter surface of the bag filter. When it is desired to adhere, if air is blown from the air blowing port 6 toward the lower back surface of the inclined diaphragm 1, the inclined diaphragm 1 vibrates due to the blown air, and the pre-coat material in the tank is formed even if a bridge is formed. It is broken by the vibration of the inclined diaphragm 1 and flows down to the inlet 4 through a gap between the lower edge of the inclined diaphragm 1 and the front plate of the precoat material filling tank 3. Then, the pre-coated material that has flowed down is accurately introduced into the inclined filtration dust collector according to the air flow discharged from the introduction port 4.

As described above, in the present invention, means for oscillating the inclined diaphragm 1 to promote the flow of the precoat material in the tank is provided;
Since both means for introducing the pre-coated material in the tank to the filtration dust collector through the input port 4 can be performed only by the air blown from the air blowing port 6, an apparatus for discharging the pre-coated material in the tank from the input port, Compared to the conventional pre-coat material feeding device that required both vibration devices for breaking the pre-coat material bridge, the entire device can be made smaller and the initial cost and running cost can be significantly reduced. .

[0009]

According to the present invention, as is apparent from the above description, an inclined diaphragm having a lower end directed toward an inlet is provided in a pre-coating material filling tank, and this is vibrated by air blown toward the lower back surface of the inclined diaphragm. The pre-coat material can be discharged into the filter dust collector easily and accurately while the bridge is broken and the pre-coat material in the tank is vibrated. Since only one mechanism is used for charging the filter and dust collector through the inlet, the size of the apparatus can be reduced and the initial cost and running cost can both be reduced, which is extremely economical. Therefore, the present invention is of great practical value as a pre-coating material charging apparatus which solves the conventional problems.
