Description

A Raymond mill tail gas dust collection device

technical field

The utility model relates to a dust collecting device, in particular to a Raymond mill tail gas dust collecting device.

Background technique

Raymond mill is widely used in the grinding process of materials in metallurgy, building materials, chemical pigments, mining and other production industries. Raymond mill crushes bulky raw materials to the required feed size, then the material is transported to the storage bin by the bucket elevator, and then evenly sent to the grinding chamber of the main machine by the electromagnetic vibrating feeder , the material entering the grinding chamber is ground between the grinding roller and the grinding ring, and the ground powder is brought to the analyzer by the air flow of the fan for classification, and the fine powder that meets the fineness requirement enters the large cyclone collector through the pipeline with the air flow, It is separated and collected, and then discharged through the unloader to become the finished product. During the milling process, the Raymond mill will produce exhaust gas with dust, which will pollute the environment.

Utility model content

The purpose of the utility model is to provide a Raymond mill tail gas dust collecting device which has a simple structure and reduces environmental pollution.

The technical solution adopted by the utility model is: a Raymond mill tail gas dust collection device, including a closed dust collection room, one side of the dust collection room is provided with an inclined air intake pipe, and the other side of the dust collection room is There is an inclined air outlet pipe, the other end of the air outlet pipe is provided with a dust collection bag, the mouth of the air outlet pipe is higher than the mouth of the air inlet pipe, and several spray ports are arranged on the air outlet pipe; There is a discharge port, and a suspension valve is arranged on the discharge port.

As a further improvement of the utility model, the included angle α between the dust collection chamber and the air inlet pipe is an acute angle, and the included angle β between the dust collection chamber and the air outlet pipe is an obtuse angle.

As a further improvement of the utility model, the dust collecting chamber is funnel-shaped.

As a further improvement of the utility model, the outlet pipe is provided with three spray ports with unequal distances and different directions.

As a further improvement of the utility model, the suspension valve includes a hollow ball and a rubber shot connected thereto.

The beneficial effects of the utility model are: the utility model has a simple structure, and through the structural design of the combination of the dust collection chamber, the dust collection bag and the spray port, the dust discharged from the tail gas of the Raymond mill is effectively collected, and the environmental pollution is reduced .

Detailed ways

Below in conjunction with Fig. 1, Fig. 2, the utility model is described further:

As shown in Figure 1 and Figure 2, a Raymond mill exhaust dust collection device includes a closed funnel-shaped dust collection chamber 2, one side of the dust collection chamber 2 is provided with an inclined intake pipe 1, and the included angle α is Acute angle, the other side of the dust collection chamber 2 is provided with an inclined air outlet pipe 5, the included angle β is an obtuse angle, the other end of the air outlet pipe 5 is provided with a dust collection bag 6, and the mouth of the air outlet pipe 5 is higher than that of the air inlet pipe 1. mouth, the air outlet pipe 5 is provided with three spray ports 4 of different directions at different distances; the bottom of the dust collection chamber 2 is provided with a discharge port 3, and a suspension valve is provided on the discharge port 3, and the suspension valve includes an empty sphere 7 and The rubber lead put 8 that is connected with it.

When the utility model is in use, the tail gas with dust enters the dust collection chamber along the inclined air intake pipe, and the larger particle dust directly falls into the bottom of the dust collection chamber due to gravity, and the bottom of the dust collection chamber is due to the rubber lead ball in the suspension valve. The collected dust will not fall, and the dust of fine particles enters the outlet pipe along with the exhaust gas, and the water mist sprayed from the spray port on the outlet pipe absorbs the dust of fine particles and flows into the dust collection room along the inclined outlet pipe. The water accumulated under the dust collection chamber reaches a certain height, due to the effect of buoyancy, the suspension valve lifts, the rubber lead ball breaks away from the discharge port, the accumulated water with a large amount of dust is discharged, the suspension valve descends, and the discharge port is closed, realizing dust collection Chamber automatic discharge.
