Embodiment 1

[0022] Please refer to figure 1 An embodiment is shown: a negative pressure bulk filling device, including a finished product tank 1, a discharge valve 2, a discharge pipe 3, an air delivery chute 4, a negative pressure pipe 5, an exhaust fan 6, an installation platform 7, Lifting device 8, telescopic part 9, bulk head 10, the discharge end of the finished product tank 1 is connected with the feed end of the discharge valve 2, and the discharge end of the discharge valve 2 is connected with the discharge pipe 3 is connected to the feed end, the side of the discharge pipe 3 is connected to the discharge end of the air delivery chute 4, the discharge end of the discharge pipe 3 is equipped with the installation platform 7, the installation The upper surface of the platform 7 is equipped with the negative pressure pipe 5, the lower surface of the installation platform 7 is equipped with the telescopic part 9, the feed end of the telescopic part 9 is connected to the discharge end...

Embodiment 2

[0025] Based on the above examples, please refer to figure 2 In an embodiment shown, the telescopic part 9 is provided with a first filter bag 91 located on the outer layer and a second filter bag 92 located on the inner layer, and the second filter bag 92 is connected to the outlet of the discharge pipe 3 The feed end is connected.

[0026] Embodiment 2 On the basis of Embodiment 1, preferably, the telescopic part 9 is set as a double-layer circular filter bag, and the second filter bag 92 in the inner layer communicates with the discharge end of the discharge pipe 3 , to facilitate the material circulation of the finished product filling 1. And in the process of air extraction by the exhaust fan 6, external impurities can be filtered out to ensure the purity of the material.

Embodiment 3

[0028] On the basis of the above embodiments, embodiment 3 shows that both the first filter bag 91 and the second filter bag 92 are provided with several support rings 93 on the inner circumference.

[0029] According to the above-mentioned embodiment, preferably, several support rings 93 are arranged on the inner circumference of the first filter bag 91 and the second filter bag 92, when the lifting device 8 drives the bulk head 10 to rise, it will squeeze and stretch part 9, the first filter bag 91 and the second filter bag 92 will be closely attached to each other, resulting in the disappearance of the hollow layer. When the exhaust fan 6 sucks air, the negative pressure generated cannot reach the bulk head 10, and the support ring 93 can be set to maintain the hollow layer. It is always present to ensure that the negative pressure reaches the bulk head 10.

Abstract

The invention belongs to the technical field of mechanical loading and unloading equipment, and particularly relates to a negative pressure bulk tank car device. The device comprises a finished product tank, a discharging pipe arranged at the discharging end of the finished product tank, a negative pressure pipe, an exhaust fan, a mounting platform, a lifting device, a telescopic part and a bulk head, wherein the lifting device is arranged on the upper surface of the mounting platform, the lifting device can drive the bulk head to move up and down, the bulk head drives the telescopic part to stretch and retract, the telescopic part and the bulk head are provided with a communicating hollow layer, the hollow layer communicates with one end of the negative pressure pipe, and the other end ofthe negative pressure pipe communicates with the top of the finished product tank. When the negative pressure bulk filling tank device carries out discharging on a carrying vehicle, the lifting device adjusts the position of the bulk head according to an actual height of the carrying vehicle, the dust raising phenomenon can be caused, the bulk head and the telescopic part can be subjected to negative pressure through the exhaust fan, the dust is sucked away and sent back to the interior of the finished product tank to be reused, the dust raising phenomenon is eliminated, the product waste isreduced, the operation efficiency is improved, and the health and environment of workers are protected.

Description

technical field [0001] The invention relates to the technical field of mechanical loading and unloading equipment, in particular to a negative pressure bulk vehicle filling device. Background technique [0002] In the loading and shipping operations of materials in building materials, electric power, metallurgy, coal, and chemical industries, the granular or powdery materials are first stored in the finished product tank, and then the loaded The car or carrier moves to the bottom of the finished product tank, and the material is discharged from the discharge port of the finished product tank. When the material is filled, the dust falling into the compartment is very large, and it is impossible to effectively suck all the dust away during the general filling process. , so there will be dust generated during loading, resulting in waste of products, affecting the operating environment, employee health and environmental protection, which is a weak link in the dust pollution cont...
