Description
Technical Field
The utility model relates to a water treatment technical field, concretely relates to area overhauls filter of manhole.
Background
In the current field of water treatment, raw water is generally taken from rivers, reservoirs, underground water and the like. Besides underground water, river and reservoir water contains more impurities, such as plant roots and stems, plastic garbage and the like. The raw water is usually provided with a flow regulating valve or other valves on a pipeline entering a water treatment plant, and the valves play a role in regulating flow or intercepting flow by regulating the opening degree of a valve core. If there is impurity in the raw water, the condition of impurity card in the case clearance appears very easily to influence the valve and use, still be difficult to the clearance simultaneously or overhaul, serious person can cause the valve to damage. If the situation happens, the front end water inlet part needs to be cut off, and the valve is detached after the pipeline is emptied, so that the maintenance work is carried out. Therefore, for pipelines with the diameter of several meters, the engineering quantity is too large, and simultaneously, larger economic loss and potential safety hazard are caused. Also for solving this type of problem, directly set up the maintenance manhole on the valve, so can increase the valve size, also improved the cost of valve simultaneously, and maintained also very inconveniently, simultaneously because of the valve structure changes, its life also can receive the influence of certain degree.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a filter of manhole is overhauld in area, with the impurity separation of former aquatic in the filter, effectively avoided impurity to the influence of valve, impurity clearance is more convenient with the maintenance.
In order to solve the technical problem, the utility model discloses take following technical scheme: the filter with the inspection manhole comprises a shell, an inspection hole blind plate, a drain pipe, a drain valve and a filter screen; the upper part of the shell is provided with an access hole; an access hole blind plate is arranged on the access hole; the bottom of the shell is provided with a drain pipe; the drain pipe is provided with a drain valve; the filter screen is detachably arranged in the shell; the filter screen is of a split structure and is formed by connecting two symmetrically arranged semicircular filter units through fasteners; the diameter of the access hole is larger than the radius of the filter screen.
Further, an underwater camera 4 with an LED illuminating lamp is arranged in the shell 1.
Furthermore, the filter unit consists of a semicircular filter frame and a stainless steel net fixed in the filter frame; two symmetrically arranged filter frames in the filter screen are connected through a plurality of fasteners.
Furthermore, both ends of the shell are provided with connecting flanges or welding grooves.
Furthermore, a lifting lug is arranged on the access hole blind plate.
Furthermore, the access hole blind plate is connected with the access hole through a sealing gasket and a fastening piece.
Furthermore, a limiting block is arranged in the shell; the limiting block is provided with a limiting groove; the bottom of filter screen is located spacing recess.
The utility model has the advantages that:
1) The utility model discloses install in the front end of pipeline valve door, with the impurity separation of former aquatic in the filter to impurity has effectively been avoided to the influence of valve. When cleaning and maintaining, because the filter screen is the components of a whole that can function independently structure, can dismantle the back and take out alone. The personnel get into the operation after also can the drainage in daily clearance, need not whole operation of hanging out, saved the cost greatly, reduced the potential safety hazard.
2) The utility model discloses a visual control filter screen jam condition of camera under water, the clearance opportunity of judging the filter screen more accurately, directly perceivedly.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of the filter screen.
Detailed Description
The technical solution of the present invention will be described clearly and completely through the following detailed description.
Referring to fig. 1 and 2, for the filter with manhole of the present invention, it includes a housing 1, a manhole 11, a manhole blind plate 12, a drain pipe 14, a drain valve 141 and a filter screen 2.
The utility model discloses a filter is installed before flow regulating valve or other valves, and the both ends of shell 1 are equipped with flange or welding groove to be connected with pipeline and valve during the installation, access hole 11 is last, and drain pipe 14 is under, is provided with drain valve 141 on the drain pipe 14.
The utility model discloses a 2 detachable of filter screen install in shell 1. The filter screen 2 is a split structure, and is formed into a full circle structure by connecting two symmetrically arranged semicircular filter units through a fastener 23.
The connection end of the filter screen 2 is firmly connected with the flange in the shell 1, and a limiting block 13 is also arranged in the shell 1; a limiting groove is formed in the limiting block 13; the bottom end of the filter screen 2 falls into a limiting groove formed by the limiting block 13, so that the filter screen can keep strength under huge water flow impact and does not deform.
The filter unit of the filter screen 2 consists of a semicircular filter frame 21 and a stainless steel net 22 fixed in the filter frame 21; two symmetrically arranged filter frames 21 of the filter screen 2 are connected by a plurality of fasteners 23. The fastener adopts screw etc..
Under the condition of water supply, the plant roots, plastic garbage and the like are separated by the filter screen 2, so that the effective filtering function is realized. When the flow displayed by the related sensor in the pipeline is lower than the set value, and the filter screen is in a blocking state monitored by the underwater camera 4, the garbage blocked in the pipeline can be judged to reach the warning value, and the cleaning work is required.
The utility model discloses install camera 4 under water in shell 1, camera 4 arranges in 11 peripheries of access hole under water, towards filter screen 2 settings, camera 4 has very high waterproof grade under water, satisfies and uses under sewer line and water washing condition. The underwater camera 4 is provided with an LED illuminating lamp, so that the underwater camera 4 can be normally used in a closed and dark environment, and a lithium battery can be adopted to provide a power supply for the underwater camera 4.
The underwater camera 4 is connected to the central control room, the monitoring picture is uploaded to the central control room after the underwater camera 4 collects underwater image information, and the blocking condition of the filter screen is visually monitored. The underwater camera 4 is combined with other related sensors in the pipeline, so that the cleaning time of the filter screen can be judged more accurately and visually, and meanwhile, the recent water source condition can be deduced, so that a related plan can be made in a targeted manner.
When cleaning, the valve at the inlet of the pipeline is closed to reduce the liquid level in the pipeline. Finally, some of the remaining liquid is drained via the bottom drain 14 and drain valve 141. An access hole blind plate 12 is arranged on the access hole 11; the access hole blind plate 12 is connected with the access hole 11 through a sealing gasket and a fastening piece; and opening the access hole blind plate on the upper part, and arranging a lifting lug on the access hole blind plate 12 to facilitate opening the access hole blind plate 12.
