Description

Technical Field

[0001] The utility model relates to the technical field of cyclones, in particular to a cyclone for a coal mill air intake. Background Art

[0002] The main function of the cyclone is gas-solid separation. The dust-containing gas enters the cyclone from the upper air inlet pipe along the tangential direction and rotates downward in a spiral around the cylinder. At this time, the dust particles rotating with the gas are thrown around under the action of strong centrifugal force, hit the inner wall of the cyclone, lose kinetic energy, and fall downward along the cylinder wall.

[0003] The cyclone dust collector is one of the indispensable equipment in the process of gas-solid separation of dusty gases generated by the coal mill air inlet during cement production. However, direct discharge after dust collection is prone to cause pipeline blockage, so it is necessary to improve the pipeline when discharging. The dust from the coal mill contains heat when the cyclone treats the coal mill, so the heat can be collected during the treatment. Utility Model Content

[0004] The utility model aims to provide a cyclone for coal mill air outlet to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a cyclone for coal mill air outlet, comprising a box body 1, a cyclone body and a box body 2,

[0006] A collecting box is embedded and fixed on the bottom end surface of the cyclone body, and a discharge pipe 1 is embedded and fixed on one end of the collecting box, and a discharge pipe 2 is embedded and fixed on the end of the collecting box away from the discharge pipe 1;

[0007] The side end surfaces of the discharge pipe 1 and the discharge pipe 2 are both equipped with a driving motor, and a spiral blade is installed on the output shaft of the driving motor through a rotating shaft;

[0008] A box body 1 is welded on the cyclone body;

[0009] The rear end surface of the box body one is welded with the box body two, and the bottom end surface of the inner wall of the box body two is equipped with a water pump.

[0010] Preferably, the bottom end surfaces of the discharge pipe 1 and the discharge pipe 2 are embedded with a discharge pipe, and a valve is installed on the discharge pipe through a flange. The discharge pipe is embedded with the bottom end surfaces of the discharge pipe 1 and the discharge pipe 2, so that when personnel process the dust-containing gas of the coal mill through the cyclone body, the dust particles fall into the collection box. After entering, the personnel can turn on the drive motor to drive the spiral blade to rotate through the rotating shaft, so that the dust particles can be driven to be discharged through the valve on the discharge pipe.

[0011] Preferably, an air outlet pipe and an air inlet pipe are provided on the cyclone body, and both the air outlet pipe and the air inlet pipe are communicated with the cyclone body. By connecting both the air outlet pipe and the air inlet pipe to the cyclone body, the air inlet pipe can be connected to the dust extraction port of the coal mill. After connection, the dust-containing gas enters the cyclone body for treatment, and the treated gas can be discharged through the air outlet pipe.

[0012] Preferably, a drain pipe is embedded and fixed on the bottom end surface of the first box body, and a valve is installed on the drain pipe through a flange. By embedding and fixing the drain pipe on the bottom end surface of the first box body, the water body entering the first box body can exchange heat with the cyclone body, and then the valve on the drain pipe can be opened for discharge.

[0013] Preferably, a connecting pipe is installed on the water pump, and the end of the connecting pipe away from the water pump is embedded and fixed in the first box body. By embedding and fixing the end of the connecting pipe away from the water pump in the first box body, personnel can open the water pump to extract the water body in the first box body and inject it into the first box body.

[0014] Preferably, a liquid inlet pipe is embedded and fixed on the top end surface of the first box body, and the liquid inlet pipe is communicated with the first box body. By communicating the liquid inlet pipe with the first box body, personnel can inject the water body required for heat exchange into the first box body for storage.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By setting the cyclone body, when personnel use the cyclone body, since both the air outlet pipe and the air inlet pipe are communicated with the cyclone body, the air inlet pipe can be connected to the dust extraction port of the coal mill. After connection, the dust-containing gas enters the cyclone body for treatment, and the treated gas can be discharged through the air outlet pipe. And since the bottom end surfaces of the first discharge pipe and the second discharge pipe are embedded and fixed with a discharge pipe, when personnel use the cyclone body to treat the dust-containing gas of the coal mill, the dust particles fall into the collection box. After entering, personnel can open the drive motor to drive the spiral blade to rotate through the rotating shaft, so as to drive the dust particles to be discharged by opening the valve on the discharge pipe, preventing blockage caused by direct discharge into the pipeline.

[0017] 2. By setting the first box body, when personnel use the cyclone body, the heat in the dust-containing gas will heat the cyclone body. During heating, since the end of the connecting pipe away from the water pump is embedded and fixed in the first box body, personnel can open the water pump to extract the water body in the first box body and inject it into the first box body. And since a drain pipe is embedded and fixed on the bottom end surface of the first box body, the water body entering the first box body can exchange heat with the cyclone body and then the valve on the drain pipe can be opened for discharge, thereby recovering the heat generated by the coal mill and preventing waste of heat.
