If some of the cage's load is broken, only the damaged part can be easily replaced, and the cage is formed of non-corrosive synthetic resin to extend the life of the filter cloth and reduce the environmental burden by reducing the weight and cost of the product. It is characteristic.

Description

Half Screw Prefab Cage {Bag Cage}

The present invention relates to a cage used for a bag filter dust collector which collects cement dust or mineral dust, and more specifically, to a semi-screw prefabricated cage structure of a bag filter dust collector that enables to combine up and down unit cages of the same type. It is about. 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, a cage made of synthetic resin has appeared, but it was difficult to form the length and shape integrally due to the structure of the gauge. Moreover, the length of the cage can be extended by combining several cages formed in units. There was a need for technical means. In addition, even if the cages are formed unitarily, the existing synthetic resin cages by hand when the operator does not fit the joining area is not well matched to force the force caused by blistering or took a lot of time There are many parts and there are pedans that fall out of cage or break when 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 reinforcing the coupling part so as to reduce the time and convenience of work and no broken parts when working. 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 5, a 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 annular engaging jaw (5a) and the outer periphery of the upper cage (5) known filter during the dust collecting operation A plurality of frames (5b) to prevent the suction into the upper cage 5 is arranged at regular intervals, the upper end of the upper cage (5a) is formed at the lower end of the upper cage (5) the upper part of the center cage (6) Two c-shaped grooves 4 'at the lower end of the upper cage 5 to be combined with the lower threaded locking jaw 7a formed in the counterclockwise and semi-screwwise, and to reinforce the shaking and breakage against the pearl core pressure during the coupling. And give a groove to the upper part of the center cage (6) It is assembled by the addition of the (4 ').

In the outer circumference of the center cage 6, a plurality of frames 6b are arranged at regular intervals so that a known filter is not sucked into the inside of the center cage 6 during the dust collecting operation, and an upper end of the center cage 6 is caught by the lower end. A hook 6a 'is formed to engage the lower threaded latching jaw 7a' formed on the upper part of the lower cage 7 in a counterclockwise manner with a counterclockwise screw thread, and also to prevent shaking and breakage against the pulsing pressure during the engagement. Two C-shaped grooves 4 'are provided at the lower end of the cage 6, and grooves are also provided at the upper portion of the lower cage 7, whereby the C-shaped hangers 4' are added to the outer periphery of the upper lower cage 7. In the dust collecting operation, a plurality of frames 7b for preventing a known filter from being sucked into the lower cage 7 are formed at regular intervals.

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.

The present invention constituted as described above, as shown in FIG. 3 when assembling the upper hook 6a at the lower end of the upper cage 5 with the lower threaded hook 7a formed at the top of the central cage 6. What is necessary is just to assemble anticlockwise counterclockwise by predetermined distance, lowering | hanging the upper latch 6a to the lower threaded latching jaw 7a. In addition, as shown in FIG. 2, the two end portions of the upper cage 5 are provided with two c-shaped grooves 4 'at regular intervals, and the c-shaped hangers 4' are fitted at the upper and middle positions when combined with the central cage 6. Cages 5 and 6 are combined.

In addition, at the lower end of the central cage 6, the upper locking hook 6a 'is assembled with the lower threaded locking jaw 7a' formed on the upper portion of the lower cage 7, as shown in FIG. The counterclockwise screwing may be assembled by a predetermined distance while lowering 6a 'toward the lower screw locking step 7a'.

In addition, as shown in FIG. 2, the lower end of the center cage 6 is provided with two c-grooves 4 'at regular intervals, and the c-hanger 4' is fitted when the bottom cage 7 is engaged. Cages 6 and 7 are combined.

In this way, the upper, middle and lower cages 5, 6 and 7 are combined, and the bag-shaped filter 8 is inserted to cover the outer circumference of the upper, middle and lower cages 5 and 6 and 7. After that, the upper end of the filter 8 is coupled to the upper end of the upper, middle, and lower cages 5, 6, and 7 by the binding band 9 to form the bag filter 10.

Subsequently, a plurality of the bag filters 10 are inserted into the 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 blue air chamber 3.

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

When a large amount of dust is collected by the outer periphery of the filter 8 in this manner, a material work for separating the collected dust from the filter 8 is performed. In this case, a horizontal longitudinal direction is performed inside the clean air chamber 3. The air of the material is ejected from the known flow tubing 13 formed to desorb the dust collected on the surface of the filter 8 and the desorbed dust is accumulated in the rotary valve 14 formed at the lower part of the dust collector 1. Will be.

As described above, the present invention allows the cage, which is in close contact with the inner circumference of the bag filter, to be combined with the upper, middle, and lower parts, so that if the cage of some of the upper, middle, and heavy loads is damaged after installation, By making it easy to replace only the parts that are used, the cage is made of synthetic resin material that does not corrode, so that the weight and cost of the product can be reduced, and the working time can be shortened.
