Abstract
The invention relates to a device for filtering sand in water flow. The device is connected with a water-consuming device through a water pipe and is characterized by comprising at least one filter module, wherein the filter modules are connected and communicated in series through water pipes; each filter module comprises a retention room and a sand sedimentation pipe, the retention room is a pipe with a cross section larger than that of the corresponding water pipe, and the sand sedimentation pipe is connected with the lower part of the retention room. Compared with the prior art, the device realizes the effect of slowing down the water flow to allow sand to be settled sufficiently through combination of each retention room and the corresponding sand sedimentation pipe, the content of sand gravel in the water flow when the water flow arrives at a water meter is obviously reduced when the device is connected with the water meter, and accordingly, the service life of the water meter is prolonged. The device is simple in structure, convenient to install, capable of being detached and convenient to clean; components of the device adopt hollow pipe structures, so that the device is low in weight and convenient to operate; the device is low in cost, wider in application range and capable of being applied to various projects needing filtering of sand in the water flow.
Description
Technical field
The present invention relates to a kind of filtering sand apparatus, especially relate to a kind of device for current filter sand.
Background technology
During dewatering well construction, with water pump groundwater abstraction and the gravel taking back-up sand measure to come in filtering underground, but still have the less gravel of part particle diameter not to be filtered, go out with subsurface flow and pass through the water meter of the monitoring rate of discharge of groundwater, easily make water meter block, and affect it and normally use.Publication number is that the utility model patent of CN200420041123.1 discloses a kind of water-meter capable of preventing from stealing electricity with filter screen; be by being fixed with its advantage of filter screen on the water inlet end surface of jet orifice; little to the change of existing water meter; when increasing cost hardly; effectively prevent the blocking of jet orifice; reduce fault rate; but in the practical application of engineering; particularly can not play maximum protective effect to water meter during dewatering construction, when gravel is more, still easily cause the blocking of water meter.Therefore current in the urgent need to a kind of device for current filter sand that can be used in Practical Project.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and a kind of device for current filter sand is provided.
Object of the present invention can be achieved through the following technical solutions:
For a device for current filter sand, this device is connected by water pipe with water consumption device part, comprises at least one filtering module, and by water pipe serial communication between described filtering module, current can pass through successively;
Described filtering module is made up of retained chamber and sand sediment pipe; Described retained chamber is the body that cross-sectional area is greater than described water pipe, and because sectional area increases, current can be retarded through retained chamber's hourly velocity; Described sand sediment pipe is connected to retained chamber bottom, because now water velocity slows down, in the sand sediment pipe that gravel is had time enough to be fully deposited on below.
Described retained chamber is connected by flange plate bolt with between water pipe.
Body in the middle of being also connected with one between described water pipe and ring flange, described middle body one end and flange hole are welded to connect, and the other end is connected with water pipe thread.
The top of described sand sediment pipe is cylindrical shape, and bottom is in funnelform structure.
Described sand sediment pipe with between retained chamber for being threaded, for convenience detach.
Described retained chamber, sand sediment pipe and water pipe are made by chromium plating stainless steel, can improve corrosion resistance, increase the service life.
Preferably, described filtering sand apparatus comprises three filtering modules.
Described water consumption device part can be water meter.
Compared with prior art, the present invention has the following advantages:
1, this device is by the combination of retained chamber and sand sediment pipe, serves the effect slowing down the abundant desilting of current, and when being connected with water meter, when current can be made to arrive water meter, grit content obviously reduces, and increases the service life of water meter;
2, this apparatus structure is simple, easy for installation, and detachably, is convenient to cleaning;
3, each parts of this device adopt the pipe structure of hollow, and therefore structure is comparatively light, convenient operation;
4, this installation cost is low, and the scope of application is comparatively wide, can be applicable to various needs in the engineering of current filter sand.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
A kind of device for current filter sand, as shown in Figure 1, this device is connected with water meter 1, this device is made up of three groups of filtering modules, i.e. three retained chamber and three sand sediment pipes, be cascaded by water pipe 3 between retained chamber 2, sand sediment pipe 4 is provided with below each retained chamber, before retained chamber is all positioned at water meter, carry out bolt by ring flange 5 between retained chamber with water pipe to be connected, body in the middle of being also connected with one between water pipe and ring flange, middle body one end and flange hole are welded to connect, and the other end is connected with water pipe thread.Retained chamber's shell has certain thickness, its underpart is provided with spiral opening and can screws on to deposit for sand sediment pipe, current are successively by arriving water meter and final discharge after three retained chamber, because the sectional area of retained chamber is larger, current are slowed down by hourly velocity, and gravel is fully fallen in sand sediment pipe, thus reduces the content flowing through grit in the current of water meter, prevent the blocking of water meter, increase its service life.
Embodiment 2
The present embodiment is substantially the same manner as Example 1, and unique difference is that a kind of device for current filter sand of the present embodiment only comprises a filtering module, and namely a retained chamber and a sand sediment pipe, can save space and material, reduce costs while filter sand.
Embodiment 3
The present embodiment is substantially the same manner as Example 1, and unique difference is that a kind of device for current filter sand of the present embodiment comprises five filtering modules, i.e. five retained chamber and five sand sediment pipes.Owing to adding two filtering modules, the present embodiment can obtain better filter sand effect, is applicable to the situation that filter sand requirement is higher.
