Cone pump for chemical fiber production and with dust setting and pressure tapping device

Abstract

The invention provides a cone pump for chemical fiber production and with a dust setting and pressure tapping device. The cone pump under pressure is provided with a dust setting device communicatingwith the inside and on one side of a feeding hole in the upper part of a pump body, an air inlet pipe A communicating with the inside is arranged at the bottom of the pump body, a discharging pipe opening is formed in the other side of the upper part of the pump body, and a pressure transmitter is arranged at the top of the dust setting device; and one side of the dust setting device is connectedwith an air inlet pipe B communicating with the inside, and an angle seat valve is arranged on the air inlet pipe B. In the using state, the dust setting device can intake compressed air through the air inlet pipe B to blow the interior of the cone pump, internal dust can be prevented from blocking the interior of the cone pump, and the compressed air enters the air inlet pipe A at the bottom endto conduct air supply production for cone pump fluidization treatment.

Description

technical field [0001] The invention relates to chemical fiber production equipment, in particular to a warehouse pump for chemical fiber production equipped with a dust suppression and pressure taking device. Background technique [0002] In the chemical fiber production unit, the warehouse pump used is a pressurized container. The warehouse pump completes the feeding and discharging through the general valve repeatedly. It is generally operated in an intermittent control mode. The filter is matched with a check valve, so that the dust entering the warehouse pump will not enter the pressure device. During use, due to the high frequency of valve action, the aging wear and damage are relatively fast, and the dust-proof filter is easy to appear. And the phenomenon of damage to the check valve, which will cause dust to enter the pressurized device and cause the material to fail to work normally. At the same time, the pressure display of the warehouse pump will also appear abnor...

[0002] In the chemical fiber production unit, the warehouse pump used is a pressurized container. The warehouse pump completes the feeding and discharging through the general valve repeatedly. It is generally operated in an intermittent control mode. The filter is matched with a check valve, so that the dust entering the warehouse pump will not enter the pressure device. During use, due to the high frequency of valve action, the aging wear and damage are relatively fast, and the dust-proof filter is easy to appear. and check valve damage, resulting in dust entering the pressure device and causing the material to fail to work normally. At the same time, the pressure display of the warehouse pump will also appear abnormal, resulting in frequent maintenance and increased operating costs.
