Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a filter unit which is mounted in a liquid feeding pipe for filtering a liquid.

[0002]

2. Description of the Related Art Conventionally, a filter for cleaning a liquid has been used in consideration of the type of liquid, impurities mixed into the liquid, and the like.
They are arranged in various places of the liquid sending pipe. Such a filter requires maintenance such as replacement of the filter or cleaning of the tube when the filter itself is clogged or the tube is clogged.

[0003] In consideration of such maintenance, a filter for filtration is often mounted in the middle of a liquid feeding pipe as a filter unit. That is, a receiving pipe for a liquid to be filtered and a discharge pipe for a filtrate are provided, and the filter unit is provided with a filtration filter between the receiving pipe and the discharge pipe, and is attached in the middle of the liquid sending pipe. And the installation of the filter unit, for the liquid sending pipe divided into the liquid sending pipe for the outflow of the liquid to be filtered and the liquid sending pipe for the inflow of the filtrate, the receiving pipe to the liquid sending pipe for the outflow, This is done by connecting the discharge pipe to the inflow liquid transfer pipe, respectively.The connection between the receiving pipe and the outflow liquid transfer pipe, and the connection between the discharge pipe and the inflow liquid transfer pipe are fixed by the connection provided at the end of each pipe. The structure is such that the flange is fixed with bolts or the like.

[0004] In this conventional mounting structure,
When removing the filter unit during maintenance, stop the liquid supply or change the liquid supply flow path to the bypass pipe, stop the liquid from flowing into the filter unit, and release the bolting of the connection flange. It is done in.

[0005] The installation and removal of the filter unit required for such maintenance may frequently occur frequently depending on the type of the liquid to be filtered and the performance of the filtration filter, and the maintenance work becomes a heavy burden. There is. Also, when removing the bolting of the connection flange, the liquid remaining in the pipe may flow out, so that the operator's hands may be stained, and depending on the type of liquid, it is necessary to prepare protective gloves. In some cases, it may not be easy to replace the filter unit.

[0006]

SUMMARY OF THE INVENTION Accordingly, the present invention improves the structure of a filter unit for filtration, which is attached in the middle of a liquid sending pipe, so that the filter unit can be attached to and detached from the liquid sending pipe. The purpose is to make it easier to do.

[0007]

In order to solve the above-mentioned problems, the present invention attaches a filter unit for filtration in the middle of a liquid sending pipe, and the filter unit comprises a receiving pipe for the liquid to be filtered and a filtrate. A discharge pipe is provided, and a filtration filter is provided between the receiving pipe and the discharge pipe, and the liquid feed pipe is divided into a liquid feed pipe for outflow of the liquid to be filtered and a liquid feed pipe for inflow of the filtrate. In the filter unit mounting structure for connecting the receiving pipe and the outflow liquid feeding pipe and connecting the discharge pipe and the inflow liquid feeding pipe, the receiving unit and the discharging pipe, The liquid feed pipe and the liquid feed pipe for inflow are arranged so as to face each other in parallel, and a detachable adapter is provided at each pipe end of the receiving pipe and the liquid feed pipe for outflow, and the discharge pipe and the liquid feed pipe for inflow. Can support the receiving pipe and the discharging pipe at the same time By providing the Do removable support member, a receiving tube and the discharge tube, the outflow liquid feed pipe and inlet liquid feed tube, was that as a simultaneously connectable withdrawal.

In the present invention, since the entire filter unit, that is, the receiving pipe, the discharge pipe, and the filtration filter can be integrally moved by the detachable supporting member, the detachable supporting member is pulled. , The receiving pipe and the discharging pipe, the outflow liquid feeding pipe and the inflow liquid feeding pipe can be simultaneously detached, and when connecting, the receiving pipe and the discharging pipe facing in parallel, the outflow liquid feeding pipe and the flowing It is possible to connect the liquid feed pipe for use only by pressing the ends of the pipes using the detachable support member. Therefore, unlike the conventional mounting structure, the entire filter unit can be mounted and removed from the liquid feed pipe by one-touch operation, and the work load required for maintenance is significantly reduced. Further, the hands of the operator due to the residual liquid in the pipe at the time of removal are not stained, so that the working efficiency is improved and the safety is high.

The detachable adapters according to the present invention are attached to the pipe ends of the receiving pipe and the outflow liquid feed pipe, and the discharge pipe and the inflow liquid feed pipe, respectively, and press the pipe ends to which the detachable adapters are attached. It has a function that can be disconnected by applying a predetermined pulling force. That is, any structure may be used as long as it has a function of allowing one-touch connection and disconnection, and has a structure capable of passing a liquid.

The filter unit of the present invention is not particularly limited in its structure, and is provided with a receiving pipe for introducing the liquid to the filtration filter and a discharge pipe for discharging the filtrate. The mounting structure of the present invention can be applied to any structure provided with a filter. The type, system, and number of filters are not particularly limited, and any filter may be used as long as liquid is introduced from a receiving pipe and filtrate that has passed through the filter is discharged.

Further, in the arrangement of the present invention, in which the receiving pipe and the discharge pipe are arranged in parallel with the outflow liquid feeding pipe and the inflow liquid feeding pipe, the receiving pipe and the discharging pipe are arranged so that the outflow liquid feeding pipe and the inflow liquid feeding pipe are formed. Any arrangement may be used as long as the pipe ends face the liquid feed pipe for use. In short, the receiving pipe and the discharging pipe may be arranged so that the pipe ends can be pressed and pulled out with respect to the pipe ends of the outflow liquid feeding pipe and the inflow liquid feeding pipe by the detachable support member. is there.
