[0025] See Figures 1 to 5 , a pocket dust collector for the tapping of an electric calcium carbide furnace of the present utility model includes a dust removal box body 1, characterized in that a bag mounting rack 2 is installed in the dust removal box body 1, a countersunk hole 2a is provided on the bag mounting rack 2, an upper dust removal bag 3 is installed in the countersunk hole 2a, a skeleton 4 is installed in the dust removal bag 3, and an elastic ring is provided on the skeleton 4;

[0026] A rotatable cover ring 9 is provided above the dust removal bag 3, and the dust removal bag 3 is detachably installed in the countersunk hole 2a through a bolt 10 on the cover ring 9.

[0027] Working principle

[0028] When the dust removal bag needs to be replaced, pull out the bolt, then rotate the cover ring, and take out the skeleton to remove the dust removal bag; after taking it out, replace the dust removal bag and install other components in reverse order. The dust removal bag is detachably installed in the countersunk hole through the elastic ring, the cover ring and the bolt. When replacing, pull out the bolt and rotate the cover ring to replace it; at the same time, the dust removal bag is fastened in the countersunk groove through the cover ring and the elastic ring, and the dust removal bag is not easy to fall off.

[0029] In some embodiments, see Figure 1 As shown, a pin slot 2b is provided on the bag mounting rack 2, a pin hole 9a is provided on the cover ring 9, and the cover ring 9 is detachably connected by being pinned in the pin hole 9a through a bolt 10. Such a design of the pin slot facilitates the installation of the bolt and also avoids the loss of the pin.

[0030] In some embodiments, see Figure 1 As shown, a dust hopper 1a is provided at the bottom of the dust removal box body 1, and a partition 1b is provided inside the dust removal box body 1, and the partition 1b is arranged above the dust hopper 1a. The partition is provided to block the heavier particles of the inhaled dust and prevent the larger particles from damaging the dust removal bag.

[0031] In some embodiments, see Figure 1As shown, on one side of the partition 1b of the dust removal box body 1, an air inlet pipe 6 is installed through a flange, and on the other side, an air outlet pipe 7 is installed through a flange. The air inlet pipe is used to suck the gas that needs to be dust-removed; the air outlet pipe is used to discharge the dust-removed gas.

[0032] In some embodiments, referring to Figure 1 As shown, a compressed air system 5 is installed on the dust removal box body 1. The compressed air system 5 is connected above the dust removal bag 3 through horizontal and vertical pipelines. The air compressor is an existing device and can be directly purchased from the market. The specific model is not limited. The air compressor is used to intermittently inject compressed air into the cloth bag to wash off the dust particles accumulated on the outer surface of the cloth bag. The vertical pipeline is a flexible corrugated pipe. In this way, when replacing the dust removal bag, the vertical pipe can be placed aside to avoid the existence of the vertical pipe affecting the removal or installation of the dust removal bag or the framework. In the present utility model, when washing off the dust particles on the surface of the dust removal bag, since the dust removal bag is supported by the counterbore and pressed by the cover ring, it is not easy to fall off either.

[0033] In some embodiments, referring to Figure 1 As shown, an ash discharge pipe 8 is installed on the ash hopper 1a through bolts, and an ash discharge valve is installed on the ash discharge pipe 8. The ash discharge valve can be purchased from the market, and the purchased one also includes a supporting ash discharge fan.

[0034] In some embodiments, referring to Figure 1 As shown, a bracket 11 is installed on the side wall of the dust removal box body 1 through angle plates.

[0035] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
