Abstract
The utility model provides an integrated form integration water purification unit's pneumatic table is swept water washing unit, is applied to the water purification treatment field, has some dross, froth attached to the box and can not in time the exhaust problem all around after solving the backwash, and pneumatic table is swept water washing unit and is become by air inlet, anti-backflow check valve, gas distribution pipe, gas distribution hole, blowdown groove, discharge port. When the equipment runs for a period of time and the filtration reaches the backwashing condition, starting the backwashing state to carry out forced backwashing, starting the pneumatic surface water sweeping and cleaning device after the forced backwashing is finished in order to clear floating slag and floating foam on the upper surface of the filtration area, carrying out pneumatic surface water sweeping and cleaning on the water surface above the filter tank, discharging the floating slag and the floating foam on the surface by entering a discharge port through pneumatic thrust, and finishing the water sweeping by the pneumatic surface after the floating slag on the upper surface of the filtration area is cleaned, so that the equipment recovers the normal water production state.
Description
Technical Field
The utility model belongs to the water purification treatment field especially relates to a pneumatic table of integrated form integration water purification unit sweeps water washing unit.
Background
In the aspect of water purification treatment, the filtering area that adopts integrated form integration equipment is mostly the homogeneity filtering pond, and backwash effect contrast siphon filtering pond etc. is better, but often has a common problem, has some dross, the froth of floating promptly after the backwash finishes to adhere to and can not in time discharge around the box, increases the operational load of filtering area, influences whole operational effect and outward appearance and feels. In order to remove the surface scum and scum, a scoop net or a water flushing device is usually manually adopted for removing the scum and scum, so that the operation cost and the maintenance workload are increased.
In view of the above situation, in order to meet the social requirement on the quality of the discharged water, the utility model discloses personnel have done serious analysis and research, provide the utility model technical scheme that can solve the problem.
Disclosure of Invention
Not enough to above-mentioned prior art, the utility model provides an integrated form integration water purification unit's pneumatic table sweeps water washing unit to solve above-mentioned technical problem.
According to the technical scheme for solving the problems, the pneumatic surface water-sweeping washing device of the integrated water purifying equipment is characterized in that the pneumatic surface water-sweeping washing device is arranged in a filtering area of the integrated water purifying equipment, and scum and floating foam remained after backwashing are cleaned through surface water-sweeping so as to replace a manual fishing net or realize an automatic function in a water washing and cleaning mode.
The method comprises the following steps: the device comprises an air inlet, a backflow prevention check valve, an air distribution pipe, an air distribution hole, a sewage discharge groove and a discharge port; the raw water is treated by processes of flocculation, precipitation, filtration and the like to reach the outgoing water quality detection standard, when the equipment runs for a period of time, the filtering effect of the filtering area is reduced, the backwashing condition is triggered, the equipment starts a backwashing state to carry out forced backwashing, in the forced backwashing washing process, a pneumatic surface sweeping water washing device is started for removing scum and floating foam on the upper surface of the filtering area, the pneumatic surface sweeping water washing device is used for carrying out pneumatic surface sweeping water washing on the water surface above the filtering pool, the surface scum and the floating foam enter a discharge port by pneumatic thrust to be discharged, and after the scum on the upper surface of the filtering area is completely swept, the pneumatic surface sweeping water is stopped, the equipment restores to a normal water production state, so that the good filtering effect of the filtering area is ensured, and the treatment.
The structure is that one side of an air inlet is connected with an air compressor or an air storage tank, the other side of the air inlet is connected with an air distribution pipe on a filtering area, a backflow prevention check valve is installed at the position of the air inlet, an air distribution hole is formed in the air distribution pipe, and a discharge port is formed in a sewage discharge groove above a filtering sand layer of the filtering area. The air distribution pipe is internally provided with a filtering area, and air distribution holes are arranged on the air distribution pipe at certain intervals.
The invention has the beneficial effects that: the space is reasonably utilized, and the water sweeping effect of the pneumatic meter is guaranteed. The air distribution holes in the air distribution pipe are arranged at certain intervals to ensure that the surface is uniformly swept and distributed with water, so that scum and floating foam are removed more conveniently.
Drawings
The present invention will now be described with reference to the accompanying drawings, in which:
fig. 1 is a schematic plan view of an embodiment of the present invention;
fig. 2 is a schematic cross-sectional view of an embodiment of the invention;
the numbering in the drawings is depicted as:
1. air inlet, 2, backflow prevention check valve, 3, air distribution pipe, 4, air distribution hole, 5, sewage discharge groove, 6 and discharge port.
Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
In this embodiment, a pneumatic table of integrated form integration water purification unit sweeps water washing unit includes: one side of the air inlet 1 is connected with an air compressor (or an air storage tank), and the other side is connected with an air distribution pipe 3 on the filtering area; a backflow prevention check valve 2 is arranged at the position of the air inlet 1; air distribution holes 4 are arranged on the air distribution pipe 3 at certain intervals; a drain outlet 6 is arranged in the sewage draining groove 5 above the filtering sand layer of the filtering area.
Specifically, the air inlet position department installation prevents the backflow check valve, and when the pneumatic table swept the water plant and started normal gas distribution, when the pneumatic table swept the water plant and stopped, the backflow check valve was opened and is prevented that the gas distribution intraductal water refluence from causing the damage to air compressor (or gas holder). The gas distribution pipe is made of PVC materials, a filter area is arranged in the gas distribution pipe in a surrounding mode, and the effect of sweeping water and distributing gas by the pneumatic meter can be guaranteed. The air distribution holes are arranged on the air distribution pipe in sequence at intervals of 200-300 mm, so that scum and floating foam can be removed more conveniently. The same height of the air distribution pipe is provided with a sewage discharge groove which is internally provided with a discharge port, so that scum and floating foam generated by sweeping water by the pneumatic meter are pushed into the discharge port of the sewage discharge groove by pneumatic thrust to be smoothly discharged.
