Problems solved by technology

[0003] The existing closed bag breaking device for ton bags occupies a large area and requires a high height from the ground, which is not suitable for small workshops; most of the ton bags with inner bags use external bags, inner bags are mechanically broken by external force, and outer bags It cannot be recycled after being destroyed, which will bring operating burden to the enterprise; the broken outer bag will pollute the raw materials, which will affect the process control and product quality of the enterprise; the upper end of the device is exposed and the suction methods such as side suction and down suction are not efficient High, the capture efficiency of the dust generated during the unloading of tons of bags is poor, and the workers are exposed to excessive dust concentrations, which endanger the health of the workers

Embodiment Construction

[0033] In conjunction with the accompanying drawings, the technical solution will be further described.

[0034] A sealed dust-proof unloading device includes a vehicle frame platform 1, a buffer frame 2, an unloading sleeve 3, a bag clamping device 4, a bag breaking blade tip 5 and a universal wheel 6.

[0035] The buffer frame 2 includes a buffer frame column 21 , a buffer plate 22 and a buffer spring 23 . The buffer frame column is welded to the four corners of the unloading device frame platform. The buffer frame is used to buffer and protect the bag clamping device and the bag breaking blade.

[0036] The unloading sleeve 3 includes a two-stage telescopic sleeve. The inner wall of the first-level sleeve 31 is provided with a circular inner protrusion, which is used for fixing the bag-breaking edge 5, passing through the vehicle frame platform 1 of the unloading device and being welded on the vehicle frame platform. A handle 33 is installed in the middle section of the ...

Abstract

The invention belongs to the technical field of material discharging devices, and discloses a closed dustproof and discharging device and a closed dustproof and discharging method. The closed dustproof and discharging device comprises a frame platform, a buffer frame arranged on the frame platform, a bag clamping device connected with the buffer frame, a discharging sleeve penetrating through theframe platform and connected with the same, and a bag breaking blade arranged on the discharging sleeve, wherein the bag clamping device is connected with the discharging sleeve. The closed dustproofand discharging device reduces the requirements for the hoisting height of a container bag, improves the portability and applicability, is compact in structure and movable, and saves the equipment installation and operation space; by performing closed discharging, further controls the raised dust, the risk that workers make contact with dust is reduced, the discharging is implemented by adopting the bag clamping device to perform closed discharging, and a feeding port is matched with an annular suction cover, thus good dust removal and dust suppression effects can be achieved; after the neck is clamped by means of the bag clamping device, an inner attached bag is damaged by means of the container bag breaking blade tip in a piercing mode, and an outer bag of the container bag cannot be damaged; and the outer bag of the container bag can be recycled, economic benefits are improved, damage to the outer bag of the container bag is small, and the outer bag can be recycled.

Description

technical field [0001] The invention belongs to the technical field of material unloading devices, and in particular relates to a mobile airtight and dust-proof unloading device and method for unloading ton-bag materials containing attached bags into silos or other storage equipment. Background technique [0002] Ton bag feeding is one of the main forms of powder feeding. The airtight unloading device of the ton bag is mostly sealed as a whole, and an air extraction device is installed outside the box to collect dust; in the sealed box, the outer bag is unloaded by destroying the outer bag by rotating the cutter head, telescopic cutter head, etc. [0003] The existing closed bag breaking device for ton bags occupies a large area and requires a high height from the ground, which is not suitable for small workshops; most of the ton bags with inner bags use external bags, inner bags are mechanically broken by external force, and outer bags It cannot be recycled after being des...
