Bag filter
Technical field
The present invention relates to a kind of filter, relate in particular to a kind of bag filter that is used to filter the condensed water that contains paraffin particles.
Background technology
Because melting point of paraffin wax is lower, paraffin particles is easy to liquefaction under higher temperature, therefore, need it is carried out condensation in production, processing and transportation, prior art generally is to carry out condensation by the nozzles spray condensed water, yet, recycling in the process of condensed water owing to be mixed with impurity such as paraffin particles in the condensed water, therefore be easy to cause the obstruction of nozzle, thereby influence the effect of condensation, increase the waste of condensed water.
Summary of the invention
Defective in view of above-mentioned prior art exists the objective of the invention is to propose a kind of bag filter that can remove the paraffin particles that contains in the condensed water.
Purpose of the present invention is achieved by the following technical programs:
A kind of bag filter, be used to filter the condensed water that contains paraffin particles, comprise body, be arranged at the water inlet pipe of described body side and be arranged at the outlet pipe of described body bottom, described water inlet pipe comprises a water inlet, described outlet pipe comprises a delivery port, described bag filter comprises that also one is used for described condensed water is pumped into water pump in the described bag filter, one is used for the refrigerator of the condensed water after condensation is filtered, at least one net tube and at least one filter bag, described water pump is connected in described water inlet, described refrigerator is connected in described delivery port, described net tube is arranged at the inside of described body, described filter bag is arranged at the inside of described net tube and the outer surface of described filter bag is close to the described inwall of netting tube, and described water inlet pipe is used for described condensed water is imported in the described filter bag.
Further, the inside of described body is provided with a support that is used for fixing described net tube.
Further, described water inlet is provided with a water-in flange that is used to connect described water pump, and described delivery port place is provided with a water-output flange that is used to connect described refrigerator.
Further, the top of described body is provided with a top cover, and described top cover is connected in described body by bolt.
Further, described top cover is provided with an exhaust outlet that is used to regulate the internal pressure of described body.
Further, the bottom of described body is provided with a sewage draining exit.
Further, described bag filter also comprises at least two feets that are used to support described body, and described feet is arranged at the bottom of described body.
Further, described bag type filtering bag comprises the filter bag of 6 net tubes and 6 correspondences, and described net tube and described water inlet pipe are distributed in the described body equably.
Compared with prior art, the invention has the beneficial effects as follows: can effectively remove the impurity such as paraffin particles that contain in the condensed water, make condensed water to utilize again smoothly.
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to understand, grasp.
Description of drawings

The specific embodiment
Shown in Fig. 1-2, bag filter of the present invention, be used to filter the condensed water that contains paraffin particles, comprise body 1, be arranged at the water inlet pipe 5 of described body 1 side and be arranged at the outlet pipe 6 of described body bottom, described water inlet pipe 5 comprises a water inlet 51, described outlet pipe 6 comprises a delivery port 61, described bag filter comprises that also one is used for described condensed water is pumped into water pump (not shown) in the described bag filter, one is used for the refrigerator (not shown) of the condensed water after condensation is filtered, at least one net tube 2 and at least one filter bag 3, described water pump is connected in described water inlet 51, described refrigerator is connected in described delivery port 61, described net tube 2 is arranged at the inside of described body 1, described filter bag 3 is arranged at the inside of described net tube 2 and the outer surface of described filter bag 3 is close to the described inwall of netting tube 2, and described water inlet pipe 5 is used for described condensed water is imported in the described filter bag 3.
The inside of described body 1 is provided with one and is used for fixing the described support (not shown) of netting tube 2, preferably, described support comprises a carriage (not shown), and described carriage is arranged between the bottom of the bottom of described net tube 2 and described body 1, plays the effect of supporting described net tube 2.Described water inlet 51 places are provided with a water-in flange 52 that is used to connect described water pump, and described delivery port 61 places are provided with a water-output flange 62 that is used to connect described refrigerator.The top of described body 1 is provided with a top cover 4, and described top cover 4 is connected in described body 1 by bolt, is provided with a silica gel sealing ring (not shown) between described top cover 4 and the described body 1, thereby guarantees its sealing, prevents to produce to leak outside.
Described bag type filtering bag comprises the filter bag 3 of 2 and 6 correspondences of 6 net tubes, and described net tube 2 and described water inlet pipe 5 are distributed in the described body 1 uniformly.
Described top cover 4 is provided with an exhaust outlet 41 that is used to regulate the internal pressure of described body 1, makes the inside of body 1 can keep the air pressure of certain level, leaks outside thereby avoid producing because of pressure is excessive.The bottom of described body 1 is provided with a sewage draining exit 11.Bag filter of the present invention also comprises at least two feets 12 that are used to support described body 1, and described feet 12 is arranged at the bottom of described body 1.Preferably, described bag filter comprises three feets 12, and this moment, stability was better.
The present invention still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the scope of protection of present invention.
