Description

One Touch Assembly Cage {Bag Cage}

The present invention relates to a cage used for a bag filter dust collector for collecting cement dust or mineral dust, and more specifically, to a one-touch prefabricated cage structure of a bag filter dust collector that enables to combine up and down unit cages of the same type. will be.

The cage of a conventional bag filter dust collector is made of a metal material such as a wire, and dust collection work is performed in a high temperature and high humidity state, and the welding part is damaged or oxidized in the process of removing the dust collected by reverse blowing. In addition to dropping the filter, the life of the filter cloth was shortened along with the closure of the broken cage. As a means to solve the above problems, synthetic resin cages have emerged, but it was difficult to integrally shape the length and shape of the cage due to the structure of the cage. Moreover, the length of the cage can be extended by combining several cages formed in units. Technical means were required. In addition, even if the cages are formed unitarily, when the operator combines the existing synthetic resin cages by hand, the joining sites do not fit well to force the force to cause blisters on the hands or take a lot of time. There are many parts and there is a closed end where the cage falls or breaks during pulsing.

The present invention devised in view of the above problems is combined with each other to connect the cage made in the longitudinal direction, and also reinforce the coupling part so that the convenience of work and no broken part with time reduction during work. It can withstand the pressure of the pulsing to be described in detail by the accompanying drawings as follows.

That is, as shown in FIGS. 1 to 4, the bag filter support plate is divided into a dust-containing air chamber 2 and a clean air chamber 3 in the dust collector 1 to remove dust contained in the air. 4) is formed in the hole of the bag filter support plate (4) is coupled to the upper cage (5) to be caught the annulus hooking jaw (5a), the outer periphery of the upper cage (5) of the known filter at the dust collection operation A plurality of half moon-shaped frames 5b for preventing suction into the cage 5 are arranged at regular intervals, and a one-touch latch 6a is formed at the lower end of the upper cage 5 so that the center cage 6 In combination with the upper bottom portion 7a, and also in contact with the lower end 6B of the upper cage 5 and the upper portion 6C of the central cage 6 to reinforce the shaking and breakage of the pulsing pressure upon joining. It comes in contact with the lower part 6D of the cage 5 and the upper end 6E of the center cage 6. At the outer periphery of the central cage 6, a plurality of half moon-shaped frames 6b are arranged at regular intervals so that a known filter is not sucked into the inside of the central cage 6 during the dust collecting operation, and at the lower end of the central cage 6, One-touch latch 6a 'is formed to engage the upper bottom portion 7a' of the lower cage 7 and also to lower the end portion 7B of the central cage 6 to reinforce the shaking and breakage against the pulsing pressure. ) And the upper cage 7C of the lower cage 7 and the lower cage 7D of the central cage 6 and the upper edge 7E of the lower cage 7 are assembled, and the outer periphery of the upper cage 7 In the dust collecting operation, a plurality of frames 7b of vandalaya are formed at regular intervals to prevent a known filter from being sucked into the inside of the lower cage 7.

In the drawings, reference numeral 8 denotes a filter 9, a binding band 10, a bag filter 11, an air inlet 12, an air outlet 13, a flow tube 14, and a rotary valve.

According to the present invention configured as described above, the upper cage 5 as shown in FIG. 2 is assembled at the lower end of the upper cage 5 with the one-touch hook 6a and the upper lower portion 7a of the central cage 6. Lower toward the center cage (6) to be assembled and at the same time contact the lower end (6B) of the upper cage (5) and the upper portion (6C) of the central cage (6) and also the lower (6D) and central cage of the upper cage (5). It comes in contact with the upper end 6E of (6).

In addition, the lower end of the center cage (6) when the one-touch hook 6a 'and the upper lower portion (7a') of the lower cage (7) when assembled as shown in Figure 2 the lower cage (6) 7, the lower end (7B) of the central cage (6) and the upper cage (7C) of the lower cage (7) and the lower (7D) and lower cage (7) of the central cage (6) It comes in contact with the upper end 7E.

In addition, if the cage is damaged when replacing the one-touch hanger (6a). (6a ') is easily separated by pressing the one-touch hanger left and right groove (6aa) in order to reinforce the tensile strength of the synthetic resin to facilitate replacement.

In this way, the upper and lower cages (5) (6) (7) are combined and the bag-shaped filter (8) is inserted to surround the outer circumference of the upper and lower cages (5) (6) (7). After installation, the upper end of the filter (8) is coupled to the upper and lower cage (5) (6) (7) by the coupling band (9) to be coupled to the back filter 10 is formed.

Subsequently, a plurality of the bag filters 10 are inserted into and installed into holes formed in the bag filter support plate 4 which divides the inside of the dust collector 1 into the vacuum chamber 2 and the clean air chamber 3.

After the bag filter 10 is installed as shown in FIG. 4, when the air containing the dust is injected into the air inlet 11 as shown in FIG. 4, the air including the dust is placed in the upper and lower cages ( 5) The dust is pressed against the outer periphery of the filter 8 supported by the frames 5b, 6b and 7b of the frames 6, 7 and 7 while the dust is pressed against the outer periphery of the filter 8. Only the clean air collected on the surface of the dust and the dust is removed is sucked into the filter (8) and moved to the upper and lower cages (5), (6) and (7), through the clean air chamber (3), and the air outlet (12). To be discharged.

In this operation, when a large amount of dust is collected on the outer periphery of the filter 8, a work of separating the collected dust from the filter 8 is performed. At this time, a horizontal length is applied to the internal powder of the clean air chamber (3). The air of the material is ejected from the well-known flow tube 13 formed in the direction to desorb dust collected on the surface of the filter 8, and the desorbed dust is supplied to the rotary valve 14 formed at the lower part of the dust collector 1. It will accumulate.

As described above, the present invention allows the cage, which is in close contact with the inner circumference of the bag filter, to be separated from the upper, middle, and lower positions so that the cage can be installed and used during installation. If part of the load is damaged, only the damaged part can be replaced easily, and the cage is made of synthetic resin that does not corrode, so that the weight of the product can be reduced, the cost can be reduced, and the working time can be shortened. will be.

The broken parts can also be collected and reused for recycling.
