Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ore dressing dust removal, in particular to an anti-overflow dust collecting hood dust removal system. Background Art
[0002] Whether it is paste cementing filling or the use of mineral processing equipment, dust removal is an indispensable part. As the beginning of the dust removal system, the dust hood plays an extremely important role. The conventional practice is to use the dust hood to seal the dust-generating point, or use the wind pressure of the fan to prevent dust leakage. However, in actual projects, the dust hood is often not closed enough or there is a population, which cannot achieve the ideal effect. In addition, the large closed dust hood also occupies a lot of space, affecting the process operation and is not conducive to production.
[0003] Existing dust collecting hoods can be divided into three parts in terms of structure, namely, a closed type, a semi-closed type, and an umbrella type hood.
[0004] Although the closed hood can completely surround the dust-generating point, it is inconvenient to operate after being closed. This type of hood will interfere with the operation and maintenance of the process. If a centralized control or remote control device is used, it will be difficult to observe after being closed. To avoid this problem, auxiliary measures must be added, which will increase the cost. In general process flows, the use of a fully enclosed dust hood is neither easy to implement nor economical. The semi-enclosed dust hood is just as the name suggests. It controls the escape of harmful substances through the suction airflow of the dust hood, and thus increases the air intake outside the hood, so its exhaust volume is larger than that of a closed hood, and it is not easy to control the cost to achieve the desired effect. The existing forms of dust hoods cannot reasonably and effectively prevent dust from overflowing.
[0005] In view of this, the present utility model is proposed. Utility Model Content

[0036] In the dust removal system of the dust collecting hood to prevent overflow proposed by the utility model, the dust generated by the dust generating equipment 100 is charged by the electric field generated between the first electrodes.
[0037] A second electrode 223 is disposed on one side of the umbrella-shaped cover 220, and a second electrode 223 is also disposed in the dust removal air duct 300. A direct current (such as Figure 1 (shown by the dashed line).
[0038] In the dust removal system of an anti-overflow dust collecting hood proposed by the utility model, direct current is passed between the second electrodes 223, so that the umbrella-shaped cover body 220 carries a charge opposite to that of the fine dust particles after passing through the first electrode by controlling the direction of the current. The charged fine dust is easily attracted by the umbrella-shaped cover body 220, thereby reducing the overflow of fine particles.
[0039] In a dust collection hood dust removal system for preventing overflow proposed by the utility model, a vibration device 600 is arranged on one side of the umbrella-shaped cover body 220 provided with a second electrode 223, and the vibration device 600 knocks down the dust on the side of the umbrella-shaped cover body 220 provided with the second electrode 223 through a vibration action. An observation hole is arranged on the other side of the umbrella-shaped cover body 220 opposite to the second electrode 223. A scraper 221 is arranged on one side of the observation hole of the umbrella-shaped cover body 220, and a handle 222 on the scraper 221 extends out of the outside of the umbrella-shaped cover body 220 through the observation hole.
[0040] In a dust removal system for an anti-overflow dust collecting hood proposed by the utility model, a vibration device 600 is provided on one side of an umbrella-shaped hood body 220. The vibration device 600 drives a slider 620 to make up and down reciprocating motions through the rotation of an active wheel 610, so that the vibration device 600 vibrates. In addition, a handle 222 located at the observation hole is connected to a scraper plate 221, so as to scrape off dust accumulated in the umbrella-shaped hood body 220.
[0041] In a dust removal system for an anti-overflow dust hood proposed by the utility model, the anti-overflow dust hood 200 dust removal system also includes a conical collector 400; the anti-overflow dust hood 200 is connected to the conical collector 400 through a dust removal air duct 300. The anti-overflow dust hood 200 dust removal system also includes a dust box 500; the dust box 500 is arranged at the lower end of the conical collector 400, and the upper end of the conical collector 400 is connected to an air outlet duct. A third electrode 410 is arranged on one side wall of the conical collector 400, and a third electrode 410 is also arranged inside the conical collector 400, and direct current is mutually connected between the third electrodes 410 (as shown by the dotted line in the figure). A vibration device 600 is arranged on the other side of the conical collector 400 where the third electrode 410 is arranged.
[0042] In a dust removal system with an anti-overflow dust hood proposed by the utility model, the dust-laden airflow passes through the anti-overflow dust hood 200 and enters the conical collector 400. Direct current is passed between the third electrodes 410 in the conical collector 400 to ionize the gas, which falls into the dust box 500 through a vibrator and can also be dusted by the principle of gravity.
[0043] In the utility model, by passing direct current through the first electrode and the second electrode 223 of the anti-overflow dust collecting hood 200, particles of different particle sizes in the dust-containing gas are ionized and adsorbed. The dust particles in the dust-containing gas can be charged and attracted by the umbrella-shaped hood body, which, on the one hand, achieves the effect of preventing the gas from the dust-producing point from overflowing, and on the other hand, takes into account the advantages of the umbrella-shaped hood body being easy to operate and observe. The dust generated by the dust-producing equipment 100 is fine dust that is easily disturbed by the external environment. It is charged by the electric field between the electric plates and attracted by the umbrella-shaped hood that is passed direct current, so as to reduce the interference of external factors and enable it to be deposited on the inner side of the umbrella-shaped hood to prevent overflow; larger particles of dust-containing gas are also deposited on the umbrella-shaped hood after being ionized by the electrodes. This structure can achieve the effect of preventing dust from overflowing at a relatively low cost. A vibration device is provided on one side of the umbrella-shaped cover, and the dust deposited on the umbrella-shaped cover falls back to the dust-generating equipment 100 through the vibration action; and a handle 222 and a scraper 221 are provided on the other side of the umbrella-shaped cover, so that the dust collector can observe the internal situation of the equipment in time, and at the same time realize the role of the population. The cone part uses gravity and ionization force to collect dust and drop it into the dust collecting box 500. The system uses a small amount of electricity and basically realizes the function of electric dust removal in the air duct part. The disadvantages of large amount of electricity consumption and easy wear of electric dust removal are eliminated and the efficiency of the terminal dust collector is improved.
