Description

Technical Field

[0001] The utility model belongs to the technical field of urea granule transportation, and in particular relates to a urea granule vacuum transportation device capable of removing urea dust. Background Art

[0002] In the production of phenolic resin, urea granules need to be pumped into the urea storage tank with a vacuum pump. However, when urea flows in the pipeline, dust will be generated due to friction. The dust will enter the vacuum pump intake valve through the vacuum pipeline. Over time, the intake valve will be blocked, affecting the suction force of the vacuum pump and affecting production. In this case, it is necessary to stop production and clean all the intake and outlet valves of the vacuum pump, which seriously affects the continuous production of phenolic resin and reduces production efficiency.

[0006] The water-soluble filter tank includes a tank body, an air inlet pipe is arranged at the lower part of the tank body, and an air outlet is arranged at the top of the tank body. The air inlet pipe is connected to the top of the urea tank through a vacuum pipeline, and the air outlet is connected to the vacuum tank through a vacuum pipeline.

[0007] Furthermore, the air inlet pipe extends into the tank body and is connected to a downwardly disposed dispersion bell mouth.

[0009] Furthermore, a water supply port is arranged at the upper part of the tank body, and a stop valve is arranged at the water supply port.

[0010] Furthermore, a water level observation mirror is arranged on the tank body for observing the water level in the tank body.

[0011] Furthermore, a maintenance manhole is provided on the tank body, and a manhole cover is installed on the maintenance manhole.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] The utility model adds a water-soluble filter tank, so that the gas containing urea dust can be dissolved in water and separated from the gas after entering the water-soluble filter tank. After the filtered gas enters the vacuum tank for buffering, it is discharged into the air by the vacuum pump without causing blockage to the vacuum valve body. After the urea dissolved in the water reaches a certain concentration, it is added to the reactor from the solution discharge valve for use.

[0014] After the water-soluble filter tank is added, the utility model reduces the time of stopping the vacuum pump for repairing, reduces the labor intensity of workers, and improves the production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
