Abstract

The utility model relates to a liquid filter, which comprises a container for receiving filter materials and filtrate and a cover body, wherein the cover body is at least provided with three pipe joints which are respectively connected with a liquid inlet pipe, a liquid outlet pipe and an exhaust pipe; the pipe joints can be respectively connected with the liquid inlet pipe, the liquid outlet pipe and the exhaust pipe by adoption of plug-in thread structures, and all the pipe joints are arranged on one side of the cover body; and a joint of the container and the cover body is provided with a combined structure. The filter is convenient to replace the overall filter and solves the problem that the filter is difficult to assemble and disassemble by means of common threaded connection. Compared with connection of rubber tubes, the leak tightness of the liquid filter is not reduced after the liquid filter is disassembled for a plurality of times. Moreover, the liquid filter can provide convenience for an operator to integrally remove the liquid inlet pipe, the liquid outlet pipe and the exhaust pipe from the top of the filter, does not require touching residual chemical liquid at the bottom of the container of the filter, and also avoids causing environmental pollution or hurting the operator due to loss of chemical agents.

Description

A kind of liquid filter

Technical field

The utility model relates to a kind of liquid filter, especially a kind of whole pipe joints is arranged at the liquid filter of lid one side, is convenient to change monolithic filter, and the process raffinate of unloading do not run off, and is safe and reliable.

Background technology

Because chemical agent has contaminative and may damage the person, therefore be applied in the central filter of chemical agent supply process and require to have good sealing property at filter process.

At present, the liquid filter on the market has the container of a sealed shape mostly, is provided with the pipe joint of two connection input pipes and efferent duct at the upper and lower end of container, and in addition because exhaust, the needs of blowdown also need to increase in addition two pipe joints.

In the course of the work, effect by the exhaust blow-down piping, the air of input pipe, efferent duct and filter interior is discharged, when treating that input pipe, efferent duct and filter interior are full of chemical agent, can under pump or gas pressure, make the chemical agent filter of flowing through smoothly, to reach the purpose that chemical agent is filtered.Yet, using after a period of time, filter stops up easily, or damages, and must unload replacing, in order to guarantee the needs of chemical agent quality and the needs of flow.

Existing liquid filter adopts the one-body molded design that can't disassemble, and input pipe, efferent duct are arranged in the upper and lower end of container separately, therefore when the chemical agent conveying loop need be changed filter, monolithic filter must be pulled out the liquid filter that more renews again from input pipe, efferent duct and exhaust or blow-down piping.When efferent duct was pulled out, container bottom may still residually have chemical liquid, and chemical liquid is flowed out along input pipe, efferent duct, not only cause pollution to operating environment, and may constitute injury to operating personnel, repeatedly dismounting also destroys interface easily, causes leakage.

The utility model content

The purpose of this utility model is to overcome shortcoming and defect of the prior art, provides that a kind of easy for installation, good airproof performance, the process raffinate of unloading do not run off, safe and reliable liquid filter.

Above-mentioned purpose of the present utility model is achieved through the following technical solutions:

A kind of liquid filter comprises a container and the lid in order to hold filter material and filtrate, it is characterized in that having three pipe joints on the lid at least, is connected with liquid input tube, liquid output pipe, blast pipe respectively.

Further, pipe joint adopts the plug-in type helicitic texture to be connected with the blast pipe formation with liquid input tube, liquid output pipe respectively, and all pipe joint is arranged at lid one side.

Further, four pipe joints can be set on the lid, be connected with liquid input tube, liquid output pipe, blast pipe, forcing pipe respectively.

Further, the joint of container and lid is provided with the winding structure, and this winding structure is made of the internal and external screw thread that is located at respectively on lid and the container, and this winding structure can also be made of the quick detach garter spring of a clamping at lid and container joint.

Further, tear garter spring open and have two semicircle shape hoop bodies that articulate mutually, and the open end of a semicircle shape hoop body is pivoted with a screw rod that has nut therein, and the open end of another semicircle shape hoop body is then corresponding to be provided with a recess that can stride into for screw rod; Container is formed with the corresponding protruding lip that stretches into semicircle shape hoop body inner ring with the junction of bottle cap; The joint of container and this bottle cap is provided with the O ring.

Compared with prior art, the utlity model has following advantage:

1. filter of the present utility model can reach the purpose that is convenient for changing monolithic filter, solves the regular screw threads connection and is difficult to install the problem that unloads, and connects with rubber tube and compares, and repeatedly dismantles sealing and does not reduce.

2. whole pipe joint systems of the utility model filter are put in order in lid one side, can the handled easily person with liquid input tube, liquid output pipe and blast pipe unification top removal from filter, need not touch the residual chemical liquid in filter container bottom, also avoid causing chemical agent to run off and cause environmental pollution or operating personnel are constituted injury.

3. the setting of winding structure, the handled easily person connects filter material removal or replacing on lid with the entire container of filter, and can brand-new container be reinstalled use, and lid can be reinstalled use, effectively reduces the consuming cost of equipment.

For further specifying design feature of the present utility model and effect, the utility model is further described below in conjunction with accompanying drawing.
