Description
Technical field
The utility model relates to active sand filtration art, refers in particular to the equal water distribution formula of a kind of low sand amount active sand filter.
Background technology
In the process of using at existing active sand filter, along with the time of using increases, the pollutant in inner active sand can get more and more, and now needs equipment downtime, and the active sand of active sand filter inside is cleaned.In addition, existing active sand filter also has following shortcoming:
Need independent coagulating basin, the depositing reservoir of arranging, make like this floor space of equipment increase, increase production cost;
The multistage filtrate adopting, needs grating, and the problems such as water head allocation is inhomogeneous often can occur.
Utility model content
The purpose of this utility model is to provide the equal water distribution formula of a kind of low sand amount active sand filter, to solve the above problems.
The equal water distribution formula of a kind of low sand amount active sand filter is provided in embodiment of the present utility model, comprise concrete filter tank, water inlet pipe, water-distributing device, casting bed, backwash water arm and system for filtering active sand, central authorities at described system for filtering active sand are provided with air lift, top at described filter is provided with sand-washing device, and described sand-washing device is also connected with flushing water outlet conduit.
Preferably, on the top of described sand-washing device, be also provided with splash-back.
Preferably, also comprise automatic inspection device, described automatic inspection device consists of a plurality of pressure sensors that connect successively, veneer plate and Master Control Room, and a plurality of described pressure sensors are distributed in the splash-back bottom of active sand filter.
Preferably, described pressure sensor is connected with described single board computer by wireless network.
Preferably, described water-distributing device consists of water-locator and the abrasive cone body that is arranged on its lower end.
Preferably, described water-locator and described abrasive cone body are integral type structure.
The equal water distribution formula of a kind of low sand amount active sand filter of the utility model above-described embodiment is the high efficiency particulate air filter that collects coagulation, clarifies, is filtered into one, and it does not need to shut down backwash; Adopt single-stage filtrate, without grating, there is no the problems such as waterpower skewness and first filtrate; Do not need backwash pump and shut down to switch with electronic, operated pneumatic valve; Without setting up coagulation, depositing reservoir, without coagulation, clarification plant equipment.Therefore floor space is compacter, and operating cost is more economical.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model specific embodiment or technical scheme of the prior art, to the accompanying drawing of required use in the specific embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation of the equal water distribution formula of a kind of low sand amount active sand filter that Fig. 1 provides for the utility model;
The process principle figure of the equal water distribution formula of a kind of low sand amount active sand filter that Fig. 2 provides for the utility model.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, will the technical solution of the utility model be carried out to clear, complete description below.Obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are resulting all other embodiment under the prerequisite of not making creative work, all belong to the scope that the utility model is protected.
As shown in Figure 1, the equal water distribution formula of a kind of low sand amount active sand filter that the utility model embodiment provides, comprise concrete filter tank, water inlet pipe 4, water-distributing device, casting bed 7, backwash water arm 3 and system for filtering active sand, central authorities at described system for filtering active sand are provided with air lift, on the top of described filter, be provided with sand-washing device 2, described sand-washing device is also connected with flushing water outlet conduit.
As shown in Figure 2, the operation principle of the equal water distribution formula of a kind of low sand amount active sand filter that the utility model embodiment provides is based on countercurrent action, former water enters the inside of the equal water distribution formula of low sand amount active sand filter from top to bottom by water inlet pipe, through the backward upper reaches of water-distributing device uniform distribution, by casting bed and outside exporting by filter liquor, arrange.In this process, former water is filtered, and the pollutant load in water reduces; In active sand, the content of pollutant increases simultaneously, and the pollutant load of lower floor's active sand is higher than upper strata active sand.The air lift that is arranged in system for filtering active sand central authorities is carried bottom active sand to the sand-washing device of filter top and being cleaned under the effect of air compressor machine, and the active sand after cleaning returns to casting bed, will clean produced pollution beyond the region of objective existence row simultaneously.
Active sand is top-down motion state in filter, and former water is played to stirring action, therefore due to this special construction, coagulation, clarification, filtration can all be completed in the body of same pond.In this external filter, active sand is in time clean, can bear higher water inlet pollutant levels.
As shown in Figure 1, the equal water distribution formula of a kind of low sand amount active sand filter that the utility model embodiment provides, is also provided with splash-back 1 on the top of described sand-washing device.
As shown in Figure 1, the equal water distribution formula of a kind of low sand amount active sand filter that the utility model embodiment provides, also comprise automatic inspection device, described automatic inspection device consists of a plurality of pressure sensors that connect successively, veneer plate and Master Control Room, and a plurality of described pressure sensors are distributed in the splash-back bottom of active sand filter.
Wherein, pressure sensor is connected with single board computer by wireless network, and single board computer is connected with Master Control Room by cable network.
When breaking down: cause for some reason Sand Filtration System normally not 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.
