Abstract
The utility model discloses an air sand-lifting device for a sand sucker for a horizontal-flow aerated grit chamber. A trefoil roots fan is arranged in the middle of a service bridge of the sand sucker, wherein an air outlet of the trefoil roots fan is connected with air pipes; the air pipes stretch downwards and are welded and communicated with sand suction openings of sand-lifting pipes; and sand discharge openings of the sand-lifting pipes are positioned in a sand discharge launder at the upper part of the air sand-lifting device. The air sand-lifting device adopts the trefoil roots fan as power, and air is injected into the sand-lifting pipes to form negative pressure to drive a water flow to lift, so that sand lifting is conducted. As sand-lifting pumps are removed, the sand-lifting pipes cannot be blocked, and the air sand-lifting device is energy-saving, efficient, safe, reliable, convenient to maintain, and long in service life.
Description
Technical field
The utility model relates to the environmental protection equipment field, and especially a kind of air of flat flow aerated grit chamber sand sucker is carried the sand device.
Background technology
What purlin car formula sand sucker was mainly used in flat flow aerated grit chamber in urban wastewater treatment firm proposes the sand operation.As shown in Figure 1, the service bridge 2 of existing purlin car formula sand sucker is by end carriage 1 supporting and the front and back slippage on track 6 at two ends, service bridge 2 belows are hung with by suspension bracket 3 the sand system of inhaling, the sand suction pipe mouth of pipe of inhaling the sand system gos deep into inhaling sand at the bottom of flat flow aerated grit chamber pond, and the sand grains on inside story, pond is risen in sediment outflow groove 5.The suction sand system of existing sand sucker all adopts the pump formula to carry sand device 4 basically; near the sand pump 7 of carrying that utilization is arranged on the sand suction pipe mouth of pipe is inhaled sand; but the sediment type more complicated in setting pot; it is not only sand grains; also often have the foreign matters such as polybag, cloth; often can make and carry sand pump 7 and stop up, motor damage even when serious has affected a whole set of normal reliable operation of carrying the sand machine equipment.
The utility model content
The applicant is for these shortcomings in above-mentioned existing production, provides a kind of air of flat flow aerated grit chamber sand sucker rational in infrastructure to carry the sand device, and is easy to maintenance, avoided the obstruction of sand extraction tube.
The technical scheme that the utility model adopts is as follows:
A kind of air of flat flow aerated grit chamber sand sucker is carried the sand device, be provided with three leaf roots blowers in the middle part of the service bridge of sand sucker, the air outlet of three leaf roots blowers is connected with tracheae, tracheae is to downward-extension and weld the suction sand mouth that is communicated with at sand extraction tube, in the superposed sediment outflow groove of the sediment ejection opening of sand extraction tube.
As further improvement in the technical proposal: the outside blimps that adopt of described three leaf roots blowers carry out the sound insulation sealing.
The beneficial effects of the utility model are as follows:
It is power that the utility model adopts three leaf roots blowers, the air Injection sand extraction tube is formed negative pressure drive the current lifting, thereby carry sand; Carry sand pump owing to having removed, thereby sand extraction tube can blockage phenomenon, efficient energy-saving, maintenance and repair is convenient, long service life and safe and reliable.
Description of drawings
Fig. 1 is the flat flow aerated grit chamber sand sucker that existing pump formula is carried sand.
Fig. 2 is for adopting flat flow aerated grit chamber sand sucker of the present utility model.
Fig. 3 is front view of the present utility model.
In figure: 1, end carriage; 2, service bridge; 3, suspension bracket; 4, the pump formula is carried the sand device; 5, sediment outflow groove; 6, track; 7, carry sand pump; 8, air is carried the sand device; 9, three leaf roots blowers; 10, blimp; 11, tracheae; 12, sand extraction tube.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 2, the utility model is improved to air with the suction sand system of flat flow aerated grit chamber sand sucker and carries sand device 8, carries sand device 4 to have replaced existing pump formula.As shown in Figure 3, the utility model is provided with three leaf roots blowers 9 at service bridge 2 middle parts, the outside blimp 10 that adopts of three leaf roots blowers 9 carries out the sound insulation sealing, the air outlet of three leaf roots blowers 9 is connected with tracheae 11, tracheae 11 is to downward-extension and weld the suction sand mouth that is communicated with at sand extraction tube 12, in the superposed sediment outflow groove 5 of the sediment ejection opening of sand extraction tube 12.
During real work, service bridge 2 is in walking on track 6 under the driving of two ends end carriage 1, three leaf roots blowers 9 pump into tracheae 11 with gas, gas enters in sand extraction tube 12 and upwards and flows, produce negative-pressure sucking at the ducted speed air flow of sand extraction tube 12, the gravel that drives in the bed load groove of pond promotes together with water, upwards enters sediment outflow groove 5.Because the utility model has been removed and carried sand pump 7, thereby in putting forward the sand process, guarantee that sand extraction tube 12 is interior unblocked, even larger foreign material can not stop up, thereby guaranteed the running reliably and with long-term of complete equipment yet.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, in the situation that without prejudice to the utility model spirit, the utility model can be done any type of modification.
Claims (2)
1. the air of a flat flow aerated grit chamber sand sucker is carried the sand device, it is characterized in that: be provided with three leaf roots blowers (9) in the middle part of the service bridge of sand sucker (2), the air outlet of three leaf roots blowers (9) is connected with tracheae (11), tracheae (11) is to downward-extension and weld the suction sand mouth that is communicated with at sand extraction tube (12), in the superposed sediment outflow groove of the sediment ejection opening of sand extraction tube (12) (5).
