Description

Technical Field

[0001] The utility model relates to the technical field of storage tank dust removal, in particular to a tower type cement storage tank dust removal device. Background Art

[0002] Cement is in a dry powder state before it is mixed with water. To ensure the dryness of the cement, it is stored in vertical or horizontal storage tanks. Cement will generate dust during storage and discharge. At present, the general way to deal with dust in cement storage tanks is to install dust removal equipment on the top. However, when cement is stored and discharged, directly passing through the dust removal equipment will increase the operating burden of the dust removal equipment. In addition, after dust removal, it is directly discharged, and the discharged air will also carry trace dust. Long-term discharge will cause certain environmental pollution. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a tower type cement storage tank dust removal device.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A tower-type cement storage tank dust removal device includes a cement storage tank, an induced draft duct, an induced draft fan, a dust collector and a washing water tank. The upper end of the cement storage tank is connected to the induced draft fan through the induced draft duct, the induced draft fan is connected to the dust collector through a pipeline, the dust collector is connected to the exhaust fan through a pipeline, and the exhaust fan is connected to the washing water tank through an exhaust pipe.

[0006] The cement storage tank includes a tank body, a top cover is provided on the top of the tank body, a conical feed port is provided between the top cover and the tank body, a gravity valve is provided at the bottom of the conical feed port, the conical feed port is provided inside the tank body, and a dust exhaust port is provided on the side wall of the top of the tank body.

[0007] The dust exhaust port is connected to the air duct.

[0008] The dust collector is a bag dust collector, and the cement dust powder collected after dust removal can be recycled.

[0009] A check valve is provided on the exhaust pipe to prevent water in the washing water tank from flowing back.

[0010] An exhaust hole plate is provided at the end of the exhaust pipe, and a plurality of exhaust holes are provided on the hole wall of the end of the exhaust pipe.

[0011] The end of the exhaust pipe is inserted below the water surface in the washing water tank, so that the exhaust hole is placed below the water surface, which can better wash and discharge the trace dust in the air.

[0012] The washing water tank includes a box body, the top of the box body is an opening, a grille cover is provided on the opening at the top of the box body, a through hole for the exhaust pipe to pass through is provided in the middle of the grille cover, and a drain valve is provided at the bottom of the side of the box body.

[0013] The beneficial effects of the utility model are as follows: a conical feed port and a gravity valve are set at the top of the cement storage tank, and the feed port and the dust discharge port are staggered to avoid that the cement at the feed port is sucked into the dust discharge port when the cement storage tank is loaded; a dust collector and a washing water tank are set, and most of the cement dust is first removed by the dust collector and recycled later, and then the air discharged after dust removal is washed and discharged through the washing water tank, so that the discharged air is cleaner, and environmental pollution caused by the cement storage tank is avoided.
