Abstract
The invention discloses an air sand extraction device for a horizontal flow aeration grit chamber sand sucker. A three-leaf root fan is arranged in the middle of a work bridge of the sand sucker; an air pipe is connected at an air outlet of the three-leaf root fan; the air pipe is downwards stretched and welded with a sand sucking hole communicated with a sand extraction pipe; and a sand discharge hole of the sand extraction pipe is located in a sand discharge slot at an upper part. According to the invention, the three-leaf root fan is used as power, air is poured into the sand extraction pipe to form a negative pressure for lifting water flow so that sand extraction is finished; and as a sand extraction pump is removed, no block occurs in the sand extraction pipe. The air sand extraction device has the advantages of energy conservation, high efficiency, good convenience for maintenance, long service life and good safety and reliability.
Description
Technical field
The present invention relates to the environmental protection equipment field, 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 the 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 the sand system of inhaling by suspension bracket 3, the sand suction pipe mouth of pipe of inhaling the sand system gos deep into inhaling sand at the bottom of the flat flow aerated grit chamber pond, and the sand grains on inside story, pond is risen in the 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 the 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, when serious even motor damage, affect a whole set of normal reliable operation of carrying the sand machine equipment.
Summary of the invention
The applicant is for these shortcomings in the 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 solution adopted in the present invention is as follows:
A kind of air of flat flow aerated grit chamber sand sucker is carried the sand device, the service bridge middle part of sand sucker is provided with three leaf roots blowers, 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 blimp that adopts of described three leaf roots blowers carries out the sound insulation sealing.
Beneficial effect of the present invention is as follows:
It is power that the present invention adopts three leaf roots blowers, the air Injection sand extraction tube is formed negative pressure drive the current lifting, thereby carry sand; Owing to having removed and carry sand pump, thereby sand extraction tube can blockage phenomenon, efficient energy-saving, and 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 invention.
Fig. 3 is front view of the present invention.
Among the 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 invention is described.
As shown in Figure 2, the present invention 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 present invention is provided with three leaf roots blowers 9 at service bridge 2 middle parts, three leaf roots blowers, the 9 outside blimps 10 that adopt carry 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 walked at 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 the sand extraction tube 12 and upwards and flows, produce negative-pressure sucking at sand extraction tube 12 ducted speed air flows, the gravel that drives in the bed load groove of pond promotes with water, upwards enters sediment outflow groove 5.Because the present invention has removed and carries sand pump 7, thereby in putting forward the sand process, guarantees that sand extraction tube 12 is interior unblocked, even larger foreign material can not stop up yet, thereby guaranteed the reliably and with long-term running of complete equipment.
Above description is explanation of the invention, is not that limited range of the present invention is referring to claim, in the situation that without prejudice to spirit of the present invention, the present invention can do any type of modification to the restriction of invention.
