Abstract
The invention discloses a filtering device of a chemical pump. The filtering device comprises a pump body and an inlet pipeline, wherein the inlet pipeline is connected with the inlet of the pump body; a filter is arranged on the inlet pipeline; the filter is a filtering bag which is mounted below the inlet pipeline through a connector; one end of the filtering bag stretches into the inlet pipeline. By adopting the filter with a simple structure, impurities in a liquid can be effectively filtered out and are prevented from entering the chemical pump, so that the service life of an impeller is prolonged, the sealing is protected, and the complete rate of the chemical pump is increased.
Description
Technical field
The present invention relates to a kind of chemical reactor, particularly a kind of chemical pump filter device.
Background technology
Chemical pump is a kind of liquid material conveying equipment being widely used in chemical field, mainly based on centrifugal pump, is applicable to extract corrosive liquids in a reservoir.Its operation principle is: before turn on pump, liquid must be full of in suction line and pump, after turn on pump, impeller High Rotation Speed, liquid wherein rotates together along with blade, under the influence of centrifugal force, fly away from impeller outwards to penetrate, liquid speed in pump case diffuser casing of injection is slack-off gradually, and pressure increases gradually, then from pump discharge, discharge pipe flows out.Now, blade center place due to liquid be thrown toward around and formed both do not had air there is no the vacuum low-pressure district of liquid, liquid in liquid pool is under the atmospheric effect in face, pond, in suction line inflow pump, liquid is continuously pumped up and continuously flows out from discharge pipe so exactly from liquid pool.When containing a large amount of solid impurity in liquid, these impurity constantly can clash into impeller, make impeller surface Accumulative damage, affect operating efficiency, even clogging impeller channel time serious, greatly reduce delivery side of pump pressure; Impurities in liquid also can impact the sealing of pump simultaneously, and pump is leaked.
Summary of the invention
It is simple that technical problem to be solved by this invention is to provide a kind of structure, can extend chemical pump maintenance cycle, the filter that protection chemical pump normally works.
A kind of chemical pump filter device of the present invention, comprises the pump housing and inlet duct, and described inlet duct is connected on the entrance of the pump housing, it is characterized in that being provided with filter on inlet duct.
Above-mentioned filter is filter bag, and this filter bag is arranged on below inlet duct by interface, and filter bag one end is stretched in inlet duct.
The present invention, can impurity effectively in filtering liquid by using this structure simple filter, makes it not enter in chemical pump, extend the service life of impeller, protect sealing, improve the serviceability rate of chemical pump.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of chemical pump filter device, comprises the pump housing 1 and inlet duct 2, and described inlet duct 2 is connected on the entrance of the pump housing 1, it is characterized in that being provided with filter on inlet duct 2.This filter is filter bag 3, and this filter bag 3 is arranged on below inlet duct 2 by interface, and filter bag 3 one end is stretched in inlet duct, tackles in inlet duct 2, filters out impurity.The interface of filter bag 3 is screwed, rear cleaned filter bag for convenience detach.
Claims (2)
1. a chemical pump filter device, comprise the pump housing (1) and inlet duct (2), described inlet duct (2) is connected on the entrance of the pump housing (1), it is characterized in that being provided with filter on inlet duct (2).
2. chemical pump filter device according to claim 1, it is characterized in that described filter is filter bag (3), this filter bag (3) is arranged on inlet duct (2) below by interface, and filter bag (3) one end is stretched in inlet duct.
