Abstract

The utility model provides an automatic inspection device for an active sand filter. The device comprises a plurality of pressure sensors, a single board computer and a master control chamber, wherein the plurality of pressure sensors, the single board computer and the master control chamber are connected in sequence; the plurality of pressure sensors are distributed at the lower part of a splash shield of the active sand filter; the number of the active sand filter is the same as that of the single board computer. According to the automatic inspection device, the plurality of pressure sensors are arranged at the lower part of the splash shield, so that failures, such as sand extracting situation, hardening situation, backwash pipe blockage and the like, in a filter chamber can be automatically detected; the running conditions of water, gas and sand channels in the equipment can be understood at any time, so that inspection workers of a water plant can be saved, and labor cost can be saved; when failures are found, the failed equipment in a filter chamber can be correctly found, so that the searching time, labor force and materials can be saved.

Description

Active sand filter automatic inspection device

Technical field

The utility model relates to a kind of inspection device, especially a kind of active sand filter automatic inspection device.

Background technology

At present, the work of patrolling and examining of existing system for filtering active sand is all to be completed by the workman of water factory.In the time that filtering layer hardens, filter tank water level inside can raise, and patrols and examines workman and sees when water level raises, and just thinks that equipment breaks down, and equipment is overhauled.

The shortcoming of aforesaid way is as follows:

Check result is checked, and the impact of workman's oneself factor is larger, may incur loss through delay the best repair time;

Go wrong by certain cover or a few complete equipment that artificially can not tell in time in filter tank the observation of water level, water level observation difficulty is larger simultaneously;

Labor intensive cost.

Summary of the invention

For the weak point existing in the problems referred to above, the utility model provides a kind of active sand filter automatic inspection device that can automatically detect the sand situation of putting forward in filter tank, the situation that hardens, backwash water pipe and whether stop up etc. other faults.

For achieving the above object, the utility model provides a kind of active sand filter automatic inspection device, formed by the multiple pressure sensors that connect successively, veneer plate and Master Control Room, multiple described pressure sensors are distributed in the splash-back bottom of active sand filter, and described active sand filter is identical with the quantity of described single board computer.

Above-mentioned active sand filter automatic inspection device, wherein, described pressure sensor is connected with described single board computer by wireless network.

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

Thereby the utility model can automatically detect the sand situation of putting forward in filter tank, the situation that hardens, backwash water pipe and the fault such as whether stops up by multiple pressure sensors are installed in splash-back bottom, and by understanding at any time the ruuning situation on device interior water, gas, Sha San road, thereby save water factory and patrol and examine workman, save cost of labor;

In the time breaking down, can accurately find out is which complete equipment in which filter tank goes wrong, to save the time of searching, man power and material.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Main description of reference numerals is as follows:

1-splash-back 2-pressure sensor

3-single board computer 4-Master Control Room

Detailed description of the invention

As shown in Figure 1, the utility model provides a kind of active sand filter automatic inspection device, formed with Master Control Room 4 by the multiple pressure sensors 2 that connect successively, veneer plate 3, multiple pressure sensors 2 can be equidistantly or are distributed in splash-back 1 bottom of active sand filter by zones of different, and active sand filter is identical with the quantity of single board computer.

Wherein, each pressure sensor 2 is connected with single board computer 3 by wireless network, and single board computer 3 is connected with Master Control Room 4 by cable network.

In the present embodiment, the quantity of active sand filter and single board computer is three.

Under normal circumstances: compressed air enters air lift, the mixture of air, sand and the water outlet of air pump of up flowing through enters liquid level control room, and the mixture of air, sand and water can have one to upward pressure to the pressure sensor of splash-back bottom.

In the time breaking down: cause for some reason that backwashing water blockage, Sand Filtration System can not normally move, casting bed hardens or part hardens while causing a backwash process water lift not put forward the situations such as sand occurring, in active sand filter, put forward sand system and certainly will not smooth or not carry sand, the mixture of gas, sand, water reduces the pressure of pressure sensor, when pressure is decreased to after a threshold values, the alarm signal that activates Master Control Room gives the alarm, administrative staff receive after caution signal, and overhaul in shakeout filter tank in time.

The foregoing is only preferred embodiment of the present utility model, is only illustrative for invention, and nonrestrictive.Those skilled in the art is understood, and in the spirit and scope that limit, can carry out many changes to it in invention claim, amendment, and even equivalence, but all will fall in protection domain of the present utility model.

Claims

1. an active sand filter automatic inspection device, it is characterized in that, be made up of the multiple pressure sensors that connect successively, veneer plate and Master Control Room, multiple described pressure sensors are distributed in the splash-back bottom of active sand filter, and described active sand filter is identical with the quantity of described single board computer.

2. active sand filter automatic inspection device according to claim 1, is characterized in that, described pressure sensor is connected with described single board computer by wireless network.
