Description

Technical Field

[0001] The present application relates to conveyor belt dust suppression technology, and in particular to a conveyor belt transportation system dust suppression device. Background Art

[0002] The main method of dust control in metal mines is to humidify the material. Spraying or watering can efficiently and conveniently remove and capture some of the dust.

[0003] However, in the northern regions where winter is relatively cold, the temperature in the workshop is low. After the dust removal water is sprayed, water accumulates in the gaps between the ore, increasing the moisture content of the original ore and causing part of the ore surface in the storage bin to freeze, forming large lumps. As a result, the heavy plate feeder is often blocked by the freezing of the ore. The existing water sprinkling and spray dust removal methods are difficult to implement in low temperature areas. Utility Model Content

[0004] The present application provides a dust suppression device for a conveyor belt transport system, which is used to solve the problem that dust removal equipment cannot capture and remove dust in low-temperature areas in winter.

[0005] The present application provides a dust suppression device for a conveyor belt transportation system, comprising a sintering plate dust collector and a dust removal box, wherein the dust removal box is arranged above the conveyor belt, and a plurality of air ducts perpendicular to the conveying direction are fixedly passed through the dust removal box horizontally, one end of the air duct is connected with the air outlet of the fan, and the other end is inserted into the sintering plate dust collector, a cover body is provided at the bottom of the dust removal box, and the cover body is connected with the lower end of the air duct through a plurality of vertical dust suction pipes, a through hole is provided above the air duct, and the top of the dust removal box is connected with a humidifier.

[0006] Optionally, the air duct is inserted into the gap between the filter plates in the sintered plate dust collector.

[0007] Optionally, the dust suction pipe is in the shape of a cone with the large diameter end facing downward.

[0008] Optionally, the dust suction pipes and the through holes on the air duct are staggered.

[0009] Optionally, a heater is provided in the dust removal box, and a heat-insulating sleeve is provided on the air duct between the sintered plate dust collector and the dust removal box.

[0010] Optionally, a honeycomb plate is fixed below the filter plate in the sintered plate dust collector via a fixing frame, and the honeycomb plate has a channel formed by a plurality of vertical through holes.

[0011] Compared with the prior art, the dust suppression device for the conveyor belt transport system provided by this application has the following beneficial effects:

[0012] The high-speed airflow created by the fan in the duct creates a negative pressure inside the dust collection tube and at the through-holes. This negative pressure draws dust from the conveyor belt through the dust collection tube and into the duct. Simultaneously, the mist delivered from the humidifier to the dust collection box is drawn into the duct through the through-holes. Dust is captured by the mist in the duct and then flows along the airflow into the sintered plate dust collector, where it is filtered and discharged as clean air. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts also fall within the scope of protection of this application.

[0023] like Figures 1-4 As shown, an embodiment of the present application provides a dust suppression device for a conveyor belt transportation system, including a sintering plate dust collector 1 and a dust removal box 2, the dust removal box 2 is arranged above the conveyor belt 3, and a plurality of air ducts 4 perpendicular to the conveying direction are fixedly passed through the dust removal box 2 horizontally, one end of the air duct 4 is connected to the air outlet of the fan 5, and the other end is inserted into the sintering plate dust collector 1, a cover body 6 is provided at the bottom of the dust removal box 2, and the cover body 6 is connected to the lower end of the air duct 4 through a plurality of vertical dust suction pipes 7, a through hole 8 is provided above the air duct 4, and the top of the dust removal box 2 is connected to the humidifier 9.

[0024] During operation, the fan 5 is started to blow air along the air duct 4 into the sintered plate dust collector 1, forming a high-speed airflow within the air duct 4. This airflow creates negative pressure within the dust suction pipe 7 at the lower end of the air duct 4 and at the through-hole 8 at the upper end. Dust generated by the conveyor belt 3 as it transports materials is drawn into the air duct 4 through the dust suction pipe 7 due to the negative pressure as it passes through the cover 6 at the lower end of the dust removal box 2. Simultaneously, the water mist produced by the humidifier 9 is conveyed into the dust removal box 2 and then simultaneously drawn into the air duct 4 due to the negative pressure generated by the through-hole 8. The dust is captured by the water mist in the air duct 4 and then discharged along the air duct 4 into the sintered plate dust collector 1. It is then filtered by the filter plate 11 within the sintered plate dust collector 1, and the filtered air is discharged through the exhaust pipe 12.

[0025] The blower 16 on the sintered plate dust collector 1 can blow back pulse air into the filter plate 11 to clean the dust attached to the filter plate 11. The dust blown off by the backflow falls to the bottom of the sintered plate dust collector 1 and is discharged through the dust outlet 13.

[0026] In this embodiment, the high-speed airflow generated by fan 5 in air duct 4 creates a negative pressure within dust collection pipe 7 and through hole 8. This negative pressure draws dust from conveyor belt 3 through dust collection pipe 7 into air duct 4. Simultaneously, the mist delivered by humidifier 9 to dust removal box 2 is drawn into air duct 4 through through hole 8. Dust is captured by the mist in air duct 4 and then flows along the airflow into sintered plate dust collector 1, where it is filtered and discharged as clean air.

[0027] In a possible implementation, the air duct 4 is inserted into the gap between the filter plates 11 in the sintered plate dust collector 1 .

[0028] The air duct 4 is inserted into the gap between the filter plates 11, so that the dust entering the sintered plate dust collector 1 along the air duct 4 can be discharged between the filter plates 11, making it easier for the filter plates 11 to filter from both sides.

[0029] like Figure 5 As shown, in a possible implementation, the dust suction pipe 7 is in the shape of a cone with the large diameter end facing downward.

[0030] The conical dust suction pipe 7 has a larger feed diameter, a larger dust absorption range, and a better effect. In addition, the diameter of the conical dust suction pipe 7 decreases from bottom to top, which has the effect of accelerating the suction of dust particles.

[0031] In a possible implementation, the dust suction pipes 7 and the through holes 8 on the air duct 4 are distributed alternately.

[0032] The staggered distribution of the dust suction pipes 7 and the through holes 8 can reduce the interference of suction between each other and also ensure the smoothness of the air flow in the air duct 4.

[0033] In a possible implementation, a heater is provided in the dust removal box 2 , and a heat-insulating sleeve 10 is provided on the air duct 4 between the sintered plate dust collector 1 and the dust removal box 2 .

[0034] The heater can heat and keep the dust removal box 2 warm, which can prevent the water mist in the dust removal box 2 from condensing and prevent ice from forming in the air duct 4. The insulation cover 10 has an insulation effect on the exposed air duct 4, preventing the exposed air duct 4 from freezing.

[0035] like Figure 6 As shown, in a possible implementation, a honeycomb plate 15 is fixed below the filter plate 11 in the sintered plate dust collector 1 via a fixing frame 14 , and the honeycomb plate 15 has a channel formed by a plurality of vertical through holes.

[0036] The dust filtered by the filter plate 11 adheres to the two sides and is blown back into the filter plate 11 by the blower 16 to make the dust fall off. The fallen dust passes through the vertical channel on the honeycomb plate 15 and falls on the dust outlet 13 at the lower end of the sintered plate dust collector 1. The honeycomb plate 15 can effectively separate the dust concentrated at the bottom to prevent the dust from floating again due to the turbulence at the upper end.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
