Abstract

A continuous type high-efficiency running sand filter mainly solves the problems that the prior filters can not complete cleaning during the operation and filtering materials are easy to harden. The continuous type high-efficiency running sand filter is characterized in that a water supply pump (1) is communicated with a high-level water tank (3) which is communicated with a water inlet distribution ring (4); the lower end in a tank body (2) is provided with a sand leakage hopper (5); a sand distribution device (6) is fixed in the tank body (2) of the upper end of the sand leakage hopper (5); the lower end of the sand leakage hopper (5) is connected with a sand collecting device (7) which is connected with a bottom tube (8) of a sand lifting tube, which is connected with a sand lifting device (9) in series; the sand lifting device (9) is respectively communicated with a sand lifting tube (10) and an air control box (11); the air control box (11) is communicated with an air compressor (12); the upper end of the sand lifting tube (10) is communicated with a sand washing device (13). The continuous type high-efficiency running sand filter not only can be operated continuously, but the cleaning is completed during the operation and the filter materials are not hardened.

Description

Continous way efficient stream sand filter

Technical field:

The utility model relates to the water filter in a kind of hydrotreater, especially continous way efficient stream sand filter.

Background technology:

Water filter adopts the technology of natural siliceous sand as filter medium, in water treatment field to be used widely.Be applied to fixed filter bed filter more, there are same characteristics in it is equipment operation certain hour, reach certain pressure after, equipment need stop to produce water, use water purification to do backwash, permanent operation can cause the minimizing of hardening of filter material layer and aquifer yield, for overcoming this problem, often use the parallel running of many covers, realize that a part is in the operation of a backwash part.This fixed filter must be furnished with bigger backwashing pump for reaching backwash rate, and the flushing water consumption is big, and water use efficiency is lower.Realize that as need automatic operation also will be furnished with the expense that automatic valve, control cabinet etc. just increase virtually.

The utility model content:

Can not in running, finish cleaning in order to solve existing filter, filtrate is prone to and hardens, the problem of energy consumption height and cleaning performance difference, the utility model provides a kind of continous way efficient stream sand filter, and this continous way efficient stream sand filter is continuously-running not only, finishes cleaning in the running, hardening can not appear in filtrate, and it is good to have a cleaning performance, need not backwashing pump, characteristic of low energy consumption.

The technical solution of the utility model is: this continous way efficient stream sand filter comprises tank body and supply-water pump, and supply-water pump is connected with elevated tank, and elevated tank distributes ring to be connected with water inlet; There is the leakage sand hopper lower end in the tank body, leak in the tank body of sand hopper upper end and be fixed with sand separator, leak the sand hopper lower end and be connected with sand trap, be connected with the sand extraction tube bottom tube on the sand trap, be connected with on the sand extraction tube bottom tube and carry the sand device, carry the sand device and be connected with sand extraction tube and gas control cabinet respectively, the gas control cabinet is connected with air compressor machine, the sand extraction tube upper end is connected with the sand-washing device that is fixed on the interior upper end of tank body, and the sand-washing device side is communicated with blow-off pipe, and there is blast pipe the sand-washing device upper end.

The utlity model has following beneficial effect: this continous way efficient stream sand filter is realized the equipment continuously-running owing to take such scheme, finishes cleaning in running; Hardening can not appear in filtrate; Unique backwash mode has strengthened cleaning performance, has improved the utilization rate of water simultaneously.Reduced energy consumption, need not backwashing pump, need not automatic valve; And floor space is little, adopts vertical installation to make the integral device structure compact more, helps applying.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model.

1-supply-water pump among the figure, the 2-tank body, the 3-elevated tank, the 4-water inlet distributes ring, and 5-leaks sand hopper, 6-sand separator, the 7-sand trap, 8-sand extraction tube bottom tube, 9-carries the sand device, 10-sand extraction tube, 11-gas control cabinet, the 12-air compressor machine, 13-sand-washing device, 14-blow-off pipe, 15-blast pipe, 16-clear water output.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

By shown in Figure 1, this continous way efficient stream sand filter comprises tank body 2 and supply-water pump 1, and supply-water pump 1 is connected with elevated tank 3, and elevated tank 3 distributes ring 4 to be connected with water inlet; There is the sand hopper 5 of leakage the lower end in the tank body 2, leak in the sand hopper 5 upper end tank bodies 2 and be fixed with sand separator 6, leak sand hopper 5 lower ends and be connected with sand trap 7, be connected with sand extraction tube bottom tube 8 on the sand trap 7, be connected with on the sand extraction tube bottom tube 8 and carry sand device 9, carry sand device 9 and be connected with sand extraction tube 10 and gas control cabinet 11 respectively, gas control cabinet 11 is connected with air compressor machine 12, sand extraction tube 10 upper ends are connected with the sand-washing device 13 that is fixed on tank body 2 interior upper ends, and sand-washing device 13 sides are communicated with blow-off pipe 14, and there is blast pipe 15 sand-washing device 13 upper ends.

During actual the use, the filtering tank running is that former water at first can be crossed supply-water pump 1 and squeezes into elevated tank 3, water flows automatically by liquid level difference in the elevated tank 3, the water inlet ring sparger 4 that enters tank body 2 bottoms is distributed to into water arm, by the quartz sand filtration layer, the downflow weir of logical tank body 2 tops of the water after the filtration flows into clear water output 16 afterwards; Tank body 2 lower curtates filter contaminated quartz sand and normally move in the product water purification process at equipment, do cleaning continuously.Process is that the quartz sand in the tank body 2 falls into the bottom by sand separator 6 and connects and put Lou in the sand hopper 5, the sand that leaks in the sand hopper 5 enters in the sand trap 7 again, carry sand device 9 and provide gas by air compressor machine 12 and gas control cabinet 11, sand is carried into by sand extraction tube bottom tube 11 and sand extraction tube 10 and sand-washing device 13, the sand extraction tube top links to each other with sand-washing device, sand extraction tube body bottom is provided with carries sand device 5, the sand of cleaning is by labyrinth, the sand-washing device 13 bottom layer of sand that falls back, gas is discharged by the blast pipe 15 at sand-washing device 13 tops, and washed-out sand water is discharged by blow-off pipe 14 and finished cleaning.This continous way efficient stream sand filter is realized the equipment continuously-running owing to take such scheme, finishes cleaning in running; Hardening can not appear in filtrate; Unique backwash mode has strengthened cleaning performance, has improved the utilization rate of water simultaneously.Reduced energy consumption, need not backwashing pump, need not automatic valve; And floor space is little, adopts vertical installation to make the integral device structure compact more, helps applying.This continous way efficient stream sand filter continuously-running is not only finished cleaning in the running thus, and hardening can not appear in filtrate, and it is good to have a cleaning performance, need not backwashing pump, characteristic of low energy consumption.
