Description

Technical Field

[0001] The utility model relates to the technical field of bulk loading machines, in particular to a dustproof finished product bulk loading machine. Background Art

[0002] Bulk loader is a common dry powder filling equipment. In calcium hydroxide production, sodium hydroxide powder is usually lifted to a storage tank or silo for temporary storage and waiting for shipment. When shipping, bulk loader is generally used. Bulk loader mainly consists of bulk head, lifting drive device, material level control device, induced draft dust suction device and fully automatic electrical control cabinet. During the entire loading process, it can automatically implement control, the whole working process is sealed, and no dust escapes.

[0003] However, the common dust suppression method for bulk loading machines is to install a negative pressure pipe at the outlet of the bulk loading machine to extract dust. Although this can achieve effective dust removal, it is based on the close cooperation between the filling head and the feeding port of the receiving bag or tank truck, and a good seal, otherwise the dust will escape from the gap between the filling head and the feeding port. At present, the discharge end of the filling head generally uses a rubber ring or a cable tie to ensure the sealing between the filling head and the feeding port, which is very inconvenient to operate and has a poor sealing effect. Utility Model Content

[0006] A dustproof finished product bulk loader, a dustproof filling head is installed on the feed pipe of the bulk machine, the dustproof filling head includes a discharge pipe, a dust removal hood and an air bag, the discharge pipe is connected with the feed pipe through a flange, the dust removal hood is installed on the discharge end of the discharge pipe, the air outlet pipe on the dust removal hood is connected with the negative pressure end of an external dust removal device, the air bag is installed on the outer periphery of the dust removal hood, and the air pipe on the air bag is connected with the air outlet end of an external air supply device.

[0007] A further technical solution is that the outer side of the airbag is arched.

[0008] A further technical solution is: the airbag is ring-shaped.

[0009] A further technical solution is: the dust hood is trumpet-shaped, and the smaller end of the dust hood is an air inlet.

[0010] A further technical solution is that a screen is provided at the bottom of the dust removal hood.

[0011] A further technical solution is that the screen is composed of a plurality of sector-shaped pieces.

[0012] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0013] The utility model proposes a dust-proof finished product bulk loader, which is provided with a dust removal cover on the filling head. When unloading materials, under the action of external dust removal equipment, an annular negative pressure airflow can be formed to extract dust, thereby achieving closed-loop dust removal and improving the dust removal effect. In addition, an air bag is installed on the outer periphery of the dust removal cover. After the air bag is inflated and expanded, it can form a close fit with the feeding port for receiving the material, thereby improving the sealing performance and effectively preventing powdery overflow.
