Abstract
The utility model relates to an intermediate lift pump for the powder transportation, which is used for reinforcement lifting for the powder transported by a powder tank truck, and the utility model belongs to the technical field of pneumatic transportation. A fixing sleeve and a fork pipe are adopted to be separately connected with a pump body through a flange, and a powder inlet port is formed by the connection of the fork pipe and a feed pipe through the flange. The upper end of an adjustable expansion pipe is provided with a nozzle, a Venturi tube is arranged on the upper end of the nozzle, and the expansion pipe can be fastened by adjusting screw nut. The utility model has the advantages of simple structure, convenient manufacture and convenient operation, and the utility model saves an intermediate material barn and a material barn pump because of the adoption of mode of the relay transportation. The utility model achieves one time conveying mode and has small occupation of land, low energy consumption and cost saving.
Description
Lift pump in the middle of a kind of pulvis is carried is used for that the pulvis that pulvis tank car force feed goes out is made reinforcement and promotes, and makes pulvis directly arrive the feed bin of higher position in course of conveying, need not to increase intermediate bunker and storehouse pump, belongs to the Pneumatic Conveying Technology field.
It is to utilize compressed-air actuated air-flow to make the pulvis fluidization that the strength of pulvis is carried, and by delivery duct, pulvis is transported to assigned address then.Before the utility model was made, in prior art, the maximum delivery height that pulvis is carried was about 20M.If be transported to higher height, must increase intermediate bunker and storehouse pump, carry out segmentation and carry.Inconvenience is made and used to this delivery system complex structure, the manufacturing cost height, and energy consumption is big.
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple in structure, can directly promote pulvis and arrive assigned address, need not to increase the middle lift pump of pulvis conveying of intermediate bunker and storehouse pump.
Main solution of the present utility model is achieved in that fixed cover 6, breeches pipe 7 are connected with the pump housing 1 by flange respectively, breeches pipe 7 and feed pipe 8 usefulness flanges are connected to the pulvis input port, nozzle 4 is installed in the upper end of adjustable telescopic pipe 3, Venturi tube 2 is installed in the upper end of nozzle 4, setting nut 5 fastening telescopic pipes 3.
Description of drawings:
Fig. 1 is the utility model structural front view:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model adopts 8 bolts that the pump housing is fixed on the mounting bracket, supports whole lift pump.The following end flanges of the pump housing 1 links to each other with compressed air inlet, and upper flanges links to each other with the pulvis delivery port, and fixed cover 6, breeches pipe 7 are connected with the pump housing 1 by flange respectively.Breeches pipe 7 and feed pipe 8 usefulness flanges are connected to the pulvis input port, and nozzle 4 is installed in the upper end of adjustable telescopic pipe 3, and the endoporus of nozzle 4 is made back taper, and collapsible like this runner plays the effect of quickening air-flow.Venturi tube 2 is installed in the upper end of nozzle 4, and setting nut 5 fastening telescopic pipes 3, setting nut 5 play the position of regulating telescopic pipe 3, the i.e. position of nozzle 4.When carrying pulvis, pulvis enters lift pump from tank car through breeches pipe 7; And pressurized air enters from the lower end flange port of the pump housing 1, shrinks back ejection at a high speed at shower nozzle mouth place air-flow.At a high speed the air-flow of ejection can form a zone of negative pressure above the front end of Venturi tube 2 and breeches pipe 7, blows away thereby pulvis sucked in the pump housing 1 and by high velocity air.Pulvis delivery pipe caliber is Φ 100mm, and delivering gas pressure is 2---2.5kg/cm
2
Compared with the prior art the utility model has the following advantages: 1, simple in structure, make and use Convenient; 2, owing to adopt the relay mode of movement, saved middle powder storehouse and storehouse pump, realized that a step arrives The mode of movement of position; 3, take up an area less, energy consumption is little, cost saving.
Claims (2)
1, lift pump in the middle of a kind of pulvis is carried, it is characterized in that adopting fixed cover (6), breeches pipe (7) to be connected with the pump housing (1) by flange respectively, breeches pipe (7) and feed pipe (8) are connected to the pulvis input port with flange, nozzle (4) is installed in the upper end of adjustable telescopic pipe (3), Venturi tube (2) is installed in the upper end of nozzle (4), the fastening telescopic pipe of setting nut (5) (3).
2, lift pump in the middle of pulvis according to claim 1 is carried is characterized in that described nozzle (4) endoporus makes back taper
