Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of port grain dust removal, in particular to a negative pressure dust removal and conveying system for bulk grain in a port. Background Art
[0002] Grain is born in the soil, grows in the fields, and is harvested in the fields. Therefore, it is inevitable that impurities such as grain husks, grain skins, and dust blocks will be mixed in. These impurities will cause friction and collision during transportation, which will produce fine dust. These fine dusts will cause dust to fly at the grain transportation site. Grain dust will explode under certain conditions, causing immeasurable losses. At the same time, grain dust is extremely harmful to the human body, causing skin allergies, respiratory diseases and other problems, causing certain harm to the health of on-site workers. Grain dust will affect the quality of grain, causing grain to heat up and deteriorate, resulting in waste and bringing varying degrees of pollution to the grain storage environment. In addition, grain dust is flammable and explosive dust. If it is not handled in time, it will damage the parts of mechanical equipment used in transportation and warehousing, shortening the service life of the equipment. Some dust adheres to the equipment, which to a certain extent accelerates the wear of the equipment and affects the service life of the equipment. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides a negative pressure dust removal and conveying system for bulk grain in a port.
[0004] The technical solution is as follows: a port bulk grain negative pressure dust removal and conveying system, including a negative pressure dust removal device. The key point is that the negative pressure dust removal device is installed on the pontoon, the connection between the pontoon and the guide rail, the connection between the various parts of the guide rail, and the loading section. The pontoon and the guide rail are connected by a floating connection mechanism, and the floating connection mechanism and the guide rail are both equipped with a conveyor belt leading to the loading section. With the above structure, multiple dust removal devices are installed throughout the port bulk grain loading and unloading and transportation process. The multiple dust removal devices can effectively remove dust generated during transportation, reduce suspended particulate matter in the air, protect the environment, improve the quality of the production environment, protect employee health, reduce dust erosion on equipment, extend the service life of equipment, reduce maintenance costs, and ensure product quality and hygienic safety.
[0005] Preferably, the guide rail is arranged along the shore, and is divided into several sections, with adjacent sections connected to each other, wherein the first section of the guide rail is connected to the floating connection mechanism, and the fourth section of the guide rail is inclined and connected to the loading section;
[0006] Negative pressure dust removal devices are installed at the connection between the first section of the guide rail and the floating connection mechanism, the connection between the first and second sections of the guide rail, and the connection between the third and fourth sections of the guide rail. With the above structure, multiple sections of guide rail are arranged according to the terrain characteristics, and multiple negative pressure dust removal devices are installed at their connection points. This can increase the number of dust removal times and improve dust removal efficiency during the conveyor belt transportation process on the guide rails, which is beneficial to environmental protection.
[0007] Preferably, the negative pressure dust removal device includes a pulse bag dust collector and a dust collection equipment room, wherein the dust collection equipment room is equipped with a power distribution cabinet connected to the pulse bag dust collector. The above structure enables efficient dust cleaning and dust removal through the pulse bag dust collector, and its operation is stable and reliable, energy-efficient, and highly adaptable. The dust collection equipment room provides stable power support for dust removal by the pulse bag dust collector.
[0008] Preferably, a negative pressure dust removal device is installed in the center of the pontoon, connected to the floating connection mechanism. With this structure, bulk grain unloaded from the cargo ship can be dusted by the pontoon hopper dust removal device, then transported to the guide rail section through the floating connection mechanism and finally delivered to the loading section.
[0009] Preferably, the negative pressure dust removal device in the loading section is located below the fourth section of guide rails, with a pulse bag dust collector positioned alongside and in communication with the receiving hopper. This structure allows bulk grain transported on the guide rail conveyor to be delivered to the loading hopper below, where the pulse bag dust collector removes dust from the bulk grain, improving storage conditions and ensuring its quality and hygiene.
[0010] As a preferred embodiment, the bottom of the negative pressure dust removal device in the loading section is pre-buried underground. The above structure can ensure the connection is firm and avoid tilting or falling during transportation, which would cause difficulties in transporting bulk grain.
[0011] Preferably, a glass observation area and an observation chamber are provided on the receiving hopper, wherein the glass observation area is provided above the observation chamber. With the above structure, the dust removal situation in the loading hopper dust removal device can be observed through the glass observation area and the observation chamber.
[0012] Preferably, the floating connection mechanism includes a connecting steel frame, a belt conveyor is provided on the connecting steel frame, and negative pressure dust removal devices are provided at both ends of the belt conveyor. One end of the bottom of the connecting steel frame is provided with a support for connecting to the pontoon, and the other end is provided with a support mechanism that can be installed on the guide rail. The bottom of the support mechanism is hinged with a sliding device, and the sliding device can slide on the guide rail. The above structure is simple and easy to build and maintain. The pontoon can choose its docking position according to the tide of the river, and has high flexibility. When the water level is low, the pontoon docks away from the shore, and the connecting steel frame and the support mechanism can be pulled to slide downward on the guide rail; on the contrary, when the water level is high, the pontoon docks close to the shore, and the support mechanism can slide upward on the guide rail to keep it stable and balanced. The hinged sliding device can always remain on the guide rail and can adapt to different terrain features.
[0013] Preferably, the support mechanism includes an upper support block and a lower support block, with a rotating structure disposed between the upper and lower support blocks, one end of the rotating structure connected to the upper support block and the other end connected to the lower support block. This structure allows for rotation within a certain range, allowing for sufficient movement when the pontoon is docked, thereby resolving the difficulty of aligning the pontoon with the guide rails.
[0014] Preferably, the upper support block and the lower support block are further provided with rotation limit pieces. The above structure can prevent excessive rotation between the upper and lower support blocks, effectively maintain the entire support mechanism, and reduce the number of maintenance times.
[0015] Compared with the existing technology, the beneficial effects of the utility model are as follows: during port transportation, through the cooperation between multiple dust removal equipment, the dust generated during transportation can be effectively removed, the suspended particulate matter in the air can be reduced, which helps to protect the environment, reduce the erosion of dust on equipment, extend the service life of equipment, reduce maintenance costs, and ensure the quality and sanitary safety of bulk grain. The negative pressure dust removal device adopts a pulse dust collector, which has good cleaning effect and large processing capacity, and can achieve efficient cleaning and dust removal.
