JPS62114624A - Bridge preventing structure of dust collector - Google Patents

Abstract

PURPOSE:To prevent the generation of the bridge in a hopper when dust is taken out, by mounting a cylindrical chute made of a flexible material to the lower opening part of the hopper provided to the lower part of a dust collector and binding the chute to close said hopper. CONSTITUTION:A dust collection container 1 has pieces of filter cloth 3 taking dust from air and a back pressure shaking apparatus 5 falling off dust of the filter cloth 3. A cylindrical chute 7 made of a flexible material is mounted to the lower opening of the hopper 6 provided to the lower part of the dust collection container 1 and tied to close the hopper 6. Therefore, at the time of back pressure shaking, the chute 7 moves up and down, and the generation of a bridge and the solidification dust in the hopper 6 are prevented by the up-and-down movement of the chute 7 and dust can be smoothly taken out. When a definite amount of dust is accumulated in the hopper 6, a clamp part 12 is united and the dust in the hopper 6 can be taken out through the chute 7.

Description

[Detailed Description of the Invention] 1. Technical field 1. The present invention is used in equipment that requires frequent switching and cleaning, and is designed to be able to take out the collected dust using a punch type! In this case, it is related to the VI system that prevents the occurrence of combustibility of the hopper.

[Background Art 1 Conventional I) This type of dust collector sucks air containing dust into a dust collection container from an inlet and filters the dust with a filter cloth provided inside the dust collection container. At the same time, the dust is forced into the hopper of the dust collection container, the filtered air is exhausted from the exhaust port, and the counterpressure is applied from the counterpressure shaking device from time to time to shake out the dust that has accumulated on the filter cloth. It was supposed to force Ho/Par to drop a dust pit. However, in such a conventional example, a date valve was used to open and close the -1 opening of the hopper, so when the counter pressure was applied from the counter pressure shaking device, the dust pockets were compressed and solidified.
There was a drawback that when a bridge formed and the date valve was opened to remove the dust chamber, it would not fall.

[Objective of the Invention 1 The present invention has been made in view of the points stated above, and the object of the present invention is to prevent the occurrence of blister with a cylinder-like structure, and to smoothly collect dust. The purpose of the present invention is to provide a dust collector with a blister-preventing structure.

[Disclosure of the Invention] Collection of Inventions W: The blizzard prevention structure of the device includes a dust collecting container 1, an inlet 2 for sucking air containing dust, and an inlet 2 provided on the upper part of the dust collecting container 1. A filter cloth 3 that removes dust from the air taken in from the air, an exhaust port 4 that exhausts the air filtered by the filter cloth 3, and a back pressure that applies reverse pressure to the filter cloth 3 to remove dust from the filter cloth 3. In a dust collector having a shaking device 5, a cylindrical chute 7 made of a flexible material is attached to the lower opening of a hopper 6 in a closed portion of the dust collecting container 1, and the chute 7 is tied up and left unused. It is characterized by consisting of a cylindrical chute 7 made of a visible material, which solves the drawbacks of the conventional example by configuring it as described above.
is installed in the lower opening of the homper 6, and the chute 7 is tied up.
2I, the chute 7 moves up and down so that it enters the tube 6 during dust collection and protrudes to r7j during back pressure shaking, and the top of this chute 7 moves up and down. This allows the dust to be taken out smoothly without causing any lumps to form in the hopper 6 and causing it to harden.

The present invention will be explained in detail below with reference to Examples.

A filter cloth 3 for filtering dust is installed in the upper part of the dust collecting container 1, an inlet port 2 is provided in the 1111I section of the dust collecting container 1, and an exhaust port is provided in the upper part of the dust collecting container 1. 4 is provided. A counter pressure shaking device 5 is disposed above the filter cloth 3 in the dust collection container 1. This counter pressure shaking device 5 is formed by providing a large number of jet ports 9 in an F supply pipe 8.

An air tank 11 is connected to the air supply pipe 8 via a valve 10 such as a solenoid valve or a diaphragm valve. The dust collecting container 1 has a hopper 6 whose diameter becomes smaller toward the lower part, and a cylindrical chute 7 is attached to the lower opening of the hopper 6. This shade 7 is made of a flexible material such as cloth. Shoot 7 is usually tightened like a string by member 1.
It is tied at 2. When air containing dust is inhaled through the suction hose or the like through the suction port 2, the dust is filtered by the filter cloth 3 and dropped into the hopper 6, and the filtered air is exhausted. Air is exhausted from port 4. At this time, the inside of the dust collecting container 1 is under negative pressure, and the chute 7 is placed in the hopper 6 as shown by the imaginary line 1 in FIG.

From time to time, air is ejected from the jet 9 of the counter pressure shaking device 5 to shake off the dust accumulated on the filter cloth 3. When a reverse pressure is applied by the reverse pressure shaking device 5, the inside of the dust collecting container 1 becomes a positive pressure, and the chute 7 protrudes toward the F direction as shown by the solid line in FIG.

Therefore, as the chute 7 moves up and down, the dust accumulated in the hopper 6 moves upwards and no dust is generated in the hopper 6. When a certain amount of dust accumulates in the hopper 6, the tightening member 12 is untied and the dust inside the hopper 6 is taken out through the system door.

1. Effects of the Invention] The present invention, as shown in Fig. 4i, attaches a cylindrical chute made of a flexible material to the opening UJ of the hopper at the bottom of the dust collection container, and closes the chute by narrowing it down. Therefore, when collecting dust, it enters the chute can hopper and 1tIJrr
: When shaking, the chute protrudes downward, and as the chute moves up and down, the dust gap moves, and a bridge is formed in the dust gap, which prevents it from hardening, and when the dust gap is taken out from the chute, it settles smoothly. It is something that can be released.
