Abstract
The utility model relates to a continuous operating float bed type sand filter, comprising a casing, a water inlet box, a water segregator, a filtering material layer, a water outlet, a spiral lifting material device, a sand distributing umbrella, an inverse sand washing separator and a water outlet for inverse washing sewage. The water separator is arranged on the middle part of the cavity of the tapered body of the casing; the water inlet box is arranged on the middle part of the outer part of the tapered body of the casing and communicated with the water separator; the spiral lifting material device is vertically arranged on the center of the casing; the sand distributing umbrella is arranged on the casing of the spiral lifting material device; the inverse sand washing separator is sheathed on the upper part of the spiral lifting material device; the filtering material layer is arranged between the casing and the spiral lifting material device. The utility model has the advantages of continuous operation, automatic filtering material cleaning, etc.
Description
The utility model relates to a kind of continuous operation floating bed formula sand filter, and it belongs to filter apparatus for filtering liquid.
At present,,, remove suspension, improve and use water quality though can scrubbing remove slag at the various water treatment filter plants of industrial use.But all exist a scabrous problem---" obstruction " jointly.In order to prevent " obstruction ", clean the dirt on the filtrate, people have to shut down and regularly clean.So not only increase working strength of workers, wasted the time, and influenced operating efficiency again.
The purpose of this utility model provide a kind of can continuous filtration, the recoil continuous operation floating bed formula sand filter of filtrate automatically.
For realizing above-mentioned task, the scheme that the utility model is taked is: this moves floating bed formula sand filter continuously, comprise housing, inlet water tank, several water knockout drums, filter material layer, delivery port, also comprise spiral extraction device, several cloth sand umbrellas, recoil sand separator and recoil sewage outlet; Several water knockout drums are arranged on the middle part of housing bullet inner chamber, inlet water tank is arranged on the outer middle part of housing bullet, and communicate with several water knockout drums, the spiral extraction device vertically is located at the central authorities of housing, the one end is fixed on the bottom of housing, the other end is contained in the top of housing, several cloth sand umbrellas are contained in respectively on the shell of spiral extraction device, the recoil sand separator be sleeved on the spiral extraction device top and with its axially at a distance of 50～200mm, the recoil sewage outlet is located at the top of recoil sand separator and passes housing, delivery port is located at the top of housing, and filter material layer is contained between housing and the spiral extraction device.
Because the utility model has adopted said structure and spiral extraction device, compares with background technology, has following advantage:
1, can move continuously, clean the dirt of filtrate automatically, make to leach water stabilization, alleviate working strength of workers.
2, the scope of application is extensive.Can be used in the water treatment system of departments such as electric power, metallurgy, mine, environmental protection.
3, the unit disposal ability is big.
4, equipment is simple.The corollary equipment that can remove the traditional filtering machine from can be saved investment in a large number as cleaning water storage tank, backwash pump, gas service etc.
5, power consumption is little, operating cost is low.
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1, the utility model comprises housing 1,2,8 water knockout drums 3 of inlet water tank, filter material layer 4, delivery port 8, also comprises 5,3 cloth sand umbrellas 6 of spiral extraction device, recoil sand separator 7 and recoil sewage outlet 9; 8 water knockout drum 3 uniform middle parts that are arranged on housing 1 bullet inner chamber, inlet water tank 2 are arranged on the outer middle part of housing 1 bullet and communicate with 8 water knockout drums 3; Spiral extraction device 5 is by shell, flight and axle are formed, spiral extraction device 5 vertically is located at the central authorities of housing 1, the one end is fixed on the bottom of housing 1, the other end is contained in the top of housing 1,3 cloth sand umbrellas 6 are contained in respectively on the shell of spiral extraction device 5, the cloth sand umbrella 6 on top is 150～240mm with the distance of recoil sand separator 7, recoil sand separator 7 is sleeved on the top of spiral extraction device 5, and it is axial at a distance of 50～200mm with spiral extraction device 5, recoil sewage outlet 9 is located at the top of recoil sand separator 7 and passes housing 1, delivery port 8 is located at the top of housing 1, and filter material layer 4 is contained between housing 1 and the spiral extraction device 5.
Operation principle of the present utility model is: untreated water quality enters inlet water tank from the water inlet of inlet water tank, enter in the housing of sand filter through 8 water knockout drums, when untreated water passes through filter material layer, filtrate is adsorbed on suspension on the filtrate, obtain clean water matter, clean water matter flows out from delivery port.In filtered water, the filtrate that the spiral extraction device constantly will adsorb suspension rises in the recoil sand separator, utilizes the impulse force of water, and filtrate is rinsed well.Clean filtrate through cloth sand umbrella equably cloth around housing.Sewage in the recoil sand separator is discharged outside the housing through the recoil sewage outlet.Repeat said process, just can realize operation continuously, automatically the purpose of cleaning.
