Description

Technical Field

[0001] The utility model relates to a smoke and dust collecting device for a closed automobile tipping platform, belonging to the technical field of closed automobile tipping platform equipment. Background Art

[0002] In industrial production, open automobile receiving chutes are conventional facilities for automobile unloading. When unloading into the chutes, automobiles generate a large amount of smoke and dust. In response to increasingly stringent environmental protection requirements, most of the original open automobile unloading forms need to be converted into closed automobile tipping platform unloading. The current method of collecting smoke and dust for general open automobile receiving chutes is to install a top suction hood above the chutes. In order to ensure the dust removal effect, the size of the top suction hood is made larger to cover the dust-producing range as much as possible. At the same time, a larger air volume is selected for the corresponding dust removal points, resulting in excessive air volume for the entire dust removal system, which increases the investment in the dust removal system. With the development of production, the current closed tipping platform unloading dust removal device cannot meet environmental protection requirements. It is very necessary to make improvements to improve the dust removal effect and save energy. Utility Model Content

DETAILED DESCRIPTION

[0016] The utility model consists of a dust removal chamber 3, an external top suction dust collecting hood 4, an internal top suction dust collecting hood 5, a side suction dust collecting hood 6, an external dust suction branch pipe 7, an internal dust suction branch pipe 8, a side dust suction branch pipe 9, a dust removal pipeline 10, an external dust suction branch pipe valve 11, an internal dust suction branch pipe valve 12, and a side dust suction branch pipe valve 13.

[0017] The figure shows that the dust removal chamber 3 is a rectangular frame structure consisting of a top panel 14, a rear panel 16, and two side panels 15. The front of the dust removal chamber 3 is open and connected to the enclosed vehicle tipping platform 1, while the bottom of the dust removal chamber 3 is open and located above the material receiving trough 2 of the enclosed vehicle tipping platform 1. When the enclosed vehicle tipping platform 1 is unloading, the rear end of the tipping platform faces the front of the dust removal chamber 3, and the material slides out of the rear end of the tipping platform and falls into the material receiving trough 2.

[0018] The figure shows that an external top-suction dust hood 4 and an internal top-suction dust hood 5 are mounted on the ceiling 14 of the dust removal chamber 3, and a side-suction dust hood 6 is mounted on the rear panel 15 of the dust removal chamber 3. The upper ends of the external top-suction dust hood 4, the internal top-suction dust hood 5, and the side-suction dust hood 6 are connected to the external dust suction branch pipe 7, the internal dust suction branch pipe 8, and the side dust suction branch pipe 9, respectively. The external dust suction branch pipe 7, the internal dust suction branch pipe 8, and the side dust suction branch pipe 8 are each connected to the dust removal duct 10, through which smoke and dust are discharged. The design wind speed of the three dust collection hoods is 3-5m / s.

[0019] The figure shows valves 11, 12, and 13 installed in the external, internal, and side suction branches 7, 8, and 9, respectively. These valves are pneumatic or electric valves, respectively. These valves regulate and cut off the amount of air being drawn.

[0020] The figure shows that the outer top suction dust hood 4, the inner top suction dust hood 5, and the side suction dust hood 6 are all umbrella-shaped. The outer top suction dust hood 4 is smaller than the inner top suction dust hood 5, and the inner top suction dust hood 5 and the side suction dust hood 6 are the same. The ratio of the length of the outer top suction dust hood 4 to the length of the inner top suction dust hood 5 is 0.8, the ratio of the width of the outer top suction dust hood 4 to the width of the inner top suction dust hood 5 is 0.8, the ratio of the length of the inner top suction dust hood 5 to the length of the side suction dust hood 6 is 1, and the ratio of the width of the inner dust hood 5 to the width of the side suction dust hood 6 is 1. The three dust hoods have the same height.

[0021] The use process of this utility model is as follows:

[0022] When the closed automobile tipping platform 1 is unloading, the inner dust suction branch pipe valve 12 and the side dust suction branch pipe valve 13 are opened. The upper dust-laden flue gas generated by the impact during unloading is captured by the inner top suction dust hood 5, and the dust-laden flue gas generated when the material falls into the silo of the receiving trough 2 is captured by the nearest side suction dust hood 5. Due to the characteristics of the dust-laden flue gas, some dust-laden flue gas still remains in the closed dust removal chamber 3 after the unloading action of the closed automobile tipping platform 1 is completed and has not completely settled into the receiving trough 2. At this time, the outer dust suction branch pipe valve 11 is opened, and the side dust suction branch pipe valve 13 is closed or the opening degree is reduced. The outer top suction dust hood 4 and the inner top suction dust hood 5 are mainly used to finally collect the remaining dust-laden flue gas in the receiving trough 2.

[0023] When the closed automobile tipping platform 1 stops unloading, the external dust suction branch pipe valve 11 and the internal dust suction branch pipe valve 12 are closed after a delay of 1 minute. The sucked materials can fall back into the receiving trough 2 according to the action of gravity. The combination of the external top suction dust collecting hood 4, the internal top suction dust collecting hood 5 and the side suction dust collecting hood 6 avoids the waste of materials and the wear of dust removal pipes caused by the suction of materials with smaller particle sizes.

[0024] An embodiment of the present invention is as follows:

[0025] The dust removal chamber 3 has a length of 6200 mm, a width of 5500 mm, and a height of 9500 mm;

[0026] The model of the external top suction dust hood 4 is 1600mm×1600mm;
