Positive-pressure conveying system device

Abstract

The invention discloses a positive-pressure conveying system device which comprises a sending tank and a storehouse. The sending tank and the storehouse are connected through a pipeline. Butterfly valves are arranged at the position of a feeding port of the sending tank and the connecting position of the bottom of the sending tank and a discharging pipe. The positive-pressure conveying system device further comprises a tonnage and standard dual-purpose unpacking and material collecting device, an exhaust noise-reduction device, a negative-pressure accelerated feeding device, a material plug forming device, a pipeline cleaning device, a pipeline blocking removing device, and a mixing device with the ratio of fed materials and inlet gas capable of being adjusted.

Description

technical field [0001] The invention relates to a positive pressure conveying system, in particular to a positive pressure conveying system device. Background technique [0002] The existing positive pressure conveying system device is only composed of a simple buffer dust removal bin, exhaust device, material conveying pipeline and storage. There are many disadvantages in the actual production process, and many aspects need to be improved in order to meet the needs of production. [0003] (1) The traditional packaging unpacking and receiving device adopts top feeding for materials of different weights. Due to the height of the receiving device itself, it is troublesome and laborious to send materials of small weight to the top; at the same time, no matter how large Heavy materials will have dust splash when feeding, polluting the air.

Problems solved by technology

[0003] (1) The traditional packaging unpacking and receiving device adopts top feeding for materials of different weights. Due to the height of the receiving device itself, it is troublesome and laborious to send materials of small weight to the top; at the same time, no matter how large Heavy materials will have dust splash when feeding, polluting the air

[0004] (2) At present, the exhaust device of the positive pressure conveying system is bagged at the exhaust port without any other treatment. Under normal circumstances, the bag will be blown off, resulting in dust pollution; second, when the bag is exhausted, it cannot be exhausted under high pressure, so it cannot operate with low energy consumption; third, the high-pressure and high-speed gas is in the discharge pipe It will generate huge noise, which is also a test for the staff; Fourth, when the materials in the buffer dust removal bin are delivered, there are still unfinished materials in the conveying pipeline at this time, and it is necessary to wait for all the materials in the conveying pipe to be delivered Only then can the next round of transportation be carried out, which wastes time, reduces the transportation volume, and wastes energy consumption

[0005] (3) At present, the feed port of the buffer dust removal bin of the positive pressure conveying system is single-port feed and vertically set. This method has reached the limit of the traditional feed speed, but the feed speed is still relatively slow, which affects the conveying system. Conveying efficiency, which ultimately affects production efficiency

[0006] (4) In the ordinary positive pressure dense-phase conveying system, when the buffer dedusting bin starts to convey materials under high pressure, the materials are disorderly and disorderly under the action of compressed air, and pass through the conveying pipeline in an uncontrollable state, which cannot achieve the best material-air ratio , a serious waste of compressed air; at the same time, the existing material process is continuous, and when the conveying pipeline reaches a certain length, the compressed air cannot push the excessively long material plug forward, resulting in the occurrence of material plugging

[0007] (5) After the materials of the existing positive pressure conveying system are conveyed, there will always be some residues in the conveying pipeline, which is a waste of raw materials and increases production costs; secondly, when the system is used again to convey different materials, it will cause The mixing of raw materials will affect the later production and even affect the quality of the product; in the past, it was feasible to dismantle the pipeline and clean it in sections, but for long-distance transportation (tens of meters, hundreds of meters), this method is time-consuming and laborious , which also increases the cost of production and processing

[0008] (6) At present, due to actual production needs, the material conveying pipelines of the positive pressure conveying system have different lengths, and some even have hundreds of meters or hundreds of meters. If the pipeline is too long, it is inevitable that the material will block the pipeline during the transportation process. Similarly, the pipeline blockage removal and disassembly process is particularly troublesome, which consumes a lot of manpower and material resources, wastes raw materials, and increases production costs.

[0009] (7) At present, during the material conveying process of the positive pressure conveying system, its feed volume and feed speed are difficult to control. If the feed volume is too small, it will cause high energy consumption, and if the feed volume is too high, the pipeline will be blocked; Affects the production efficiency in the later stage; at this stage, there is a lack of a device that can adjust the feed and air intake ratio through intelligent control, so as to achieve the best delivery state of the material supply speed and supply volume
