AI Technical Summary
During the process of loading ton packs, the gas from the ore powder carries fine materials and produces dust, affecting the operating vision, environmental sanitation and the health of the operators.
A ton-packing dust-proof structure is designed, including one and two anti-dust pipes. A discharge valve is provided on the cutting pipe. The exhaust port height of the anti-dust pipe is higher than the highest point of the material in the silo to prevent gas from causing dust to overflow.
Effectively reduce or avoid dust problems when feeding tons of packs, prevent fine-grained dust from entering the environment, and improve operating conditions and environmental sanitation.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of dust control, in particular to a dust prevention structure for unloading ton bags. Background Art
[0002] When using ton bags to receive materials at the silo discharge port, in order to ensure smooth material reception, the ton bags will be blown up with nitrogen first. This will also cause the mineral powder to fall into the ton bag from the silo receiving pipe. The gas in the ton bag will be squeezed out by the mineral powder and carry some fine materials to diffuse near the ton bag port, generating dust. This not only affects the working field and environmental hygiene, but also endangers the health of the operators.
[0003] Therefore, it is necessary to develop a dust-proof structure for unloading ton bags to reduce or avoid the dust problem when using ton bags to receive materials. Utility Model Content
[0004] The main purpose of the utility model is to provide a dust-proof structure for unloading ton bags, so as to reduce or avoid the dust problem when connecting materials with ton bags.
[0005] In order to achieve the above-mentioned purpose, the utility model is implemented according to the following technical scheme:
[0006] A dust-proof structure for unloading ton bags comprises a silo, a ton bag and a unloading pipe connected to the bottom of the silo, wherein the upper and lower parts of the unloading pipe are respectively connected to dust-proof pipe one and dust-proof pipe two, and a unloading valve is also provided on the unloading pipe between the dust-proof pipe one and dust-proof pipe two, an annular groove one is provided at the bottom of the unloading pipe, a material receiving end of the ton bag is connected to the annular groove one through a fixing piece one, and an exhaust port is provided at one end of the dust-proof pipe one and dust-proof pipe two away from the unloading pipe, and the height of the exhaust port is higher than the highest point of the material in the silo.
[0007] Preferably, the exhaust port ends of the dust prevention duct one and the dust prevention duct two are respectively provided with an annular groove two, and dust filter bags are respectively sleeved on the exhaust ports. The bag openings of the dust filter bags are connected to the annular groove two through fixing parts two. By sleeved dust cloth bags on the exhaust ports, particularly fine mineral powder and smoke can be prevented from being discharged into the environment.
[0008] Preferably, the fixing member 1 and the fixing member 2 both adopt O-shaped elastic rubber rings to facilitate the rapid disassembly and installation of the ton bag and the dust filter bag.
[0009] The utility model also includes other components that enable it to be used normally, and these components all adopt conventional technical means in the field. In addition, the devices and components not limited in the utility model all adopt conventional technical means in the field, such as silos, discharge valves, O-type rubber sealing rings and dust filter bags, etc. In the specific implementation process, the field can select appropriate equipment or component models according to specific working scenarios.
[0010] The working principle of the utility model is: when the mineral powder falls from the discharge pipe of the silo into the ton bag, the gas carrying fine materials squeezed out by the mineral powder in the ton bag can diffuse upward along the anti-dust pipe 1 and the anti-dust pipe 2, and will not diffuse near the mouth of the ton bag, thereby avoiding the generation of dust. Since the exhaust port extends above the highest point of the material in the silo, when the gas overflows from the exhaust ports of the anti-dust pipe 1 and the anti-dust pipe 2, the dust entrained with the gas in the anti-dust pipe 1 and the anti-dust pipe 2 will fall back into the discharge pipe under the action of gravity and finally be loaded into the ton bag.
[0011] Compared with the prior art, the beneficial effect of the utility model is that it only requires a simple modification of the unloading pipeline of the original silo to reduce or avoid the dust problem caused by using ton bags to receive materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention is further described below with reference to specific embodiments and in conjunction with the accompanying drawings. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.
[0016] Example
[0017] like Figures 1 to 3As shown, this embodiment proposes a dust-proof structure for unloading ton bags, comprising a silo 1, a ton bag 11 and a unloading pipe 2 connected to the bottom of the silo, the upper and lower parts of the unloading pipe are respectively connected to an anti-dust pipe 1 3 and an anti-dust pipe 2 4, a unloading valve 5 is also provided on the unloading pipe between the anti-dust pipe 1 and the anti-dust pipe 2, an annular groove 1 6 is provided at the bottom of the unloading pipe, the material receiving end of the ton bag is connected to the annular groove 1 through a fixing part 7, and an exhaust port is provided at one end of the anti-dust pipe 1 and the anti-dust pipe 2 away from the unloading pipe, and the height of the exhaust port is higher than the highest point of the material in the silo.
[0018] In this embodiment, the exhaust port ends of the dust prevention duct one and the dust prevention duct two are respectively provided with an annular groove two 8, and dust filter bags 9 are respectively sleeved on the exhaust ports. The bag openings of the dust filter bags are connected to the annular groove two through fixing parts two 10. By sleeved dust-proof cloth bags on the exhaust ports, particularly fine mineral powder dust can be prevented from being discharged into the environment.
[0019] Specifically, the fixing part 1 and the fixing part 2 both adopt O-shaped elastic rubber rings, which facilitate the rapid disassembly and installation of the ton bag and the dust filter bag.
[0020] The working principle of the utility model is: when the mineral powder falls from the discharge pipe of the silo into the ton bag, the gas carrying fine materials squeezed out by the mineral powder in the ton bag can diffuse upward along the anti-dust pipe 1 and the anti-dust pipe 2, and will not diffuse near the mouth of the ton bag, thereby avoiding the generation of dust. Since the exhaust port extends above the highest point of the material in the silo, when the gas overflows from the exhaust ports of the anti-dust pipe 1 and the anti-dust pipe 2, the dust entrained with the gas in the anti-dust pipe 1 and the anti-dust pipe 2 will fall back into the discharge pipe under the action of gravity and finally be loaded into the ton bag.
[0021] The technical solution of the present utility model is not limited to the above-mentioned specific embodiments, and all technical variations made according to the technical solution of the present utility model fall within the protection scope of the present utility model.
