Abstract
The utility model discloses a double-sleeve type delivery pipe for a downwards-pumping type bin pump. The double-sleeve type delivery pipe comprises a downwards-pumping type bin pump body and a double-sleeve type delivery pipe body mounted on the lower portion of the downwards-pumping type bin pump body. The double-sleeve type delivery pipe body is composed of two connection flanges, a delivery-pipe outer sleeve, a delivery-pipe lining pipe and a feed pipe, the delivery-pipe outer sleeve and the delivery-pipe lining pipe are placed horizontally, the delivery-pipe lining pipe is mounted on the inner side of the delivery-pipe outer sleeve, the feed pipe is located below the double-sleeve type delivery pipe body and communicated with the delivery-pipe lining pipe, the two connection flanges are mounted at two ends of the delivery-pipe outer sleeve respectively, and one connection flange is connected with a delivery air source while the other one is connected with a discharge pipe. When the delivery-pipe lining pipe is worn through, normal delivery of the downwards-pumping type bin pump is unaffected since the delivery-pipe outer sleeve is mounted outside the delivery-pipe lining pipe, and service life of the downwards-pumping type bin pump is prolonged.
Description
Technical field
The utility model relates to a kind of tubular type delivery pipe, relate in particular to a kind of under draw two telescoping delivery pipes of formula storehouse pump.
Background technology
At present, under, draw formula storehouse pump and be widely used in various air-transport systems.Wearing and tearing to delivery pipe during due to mass transport, resource has been wasted in too early can not using due to delivery pipe wearing and tearing under causing, to draw formula storehouse pump.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provide a kind of under draw two telescoping delivery pipes of formula storehouse pump.
The purpose of this utility model is achieved through the following technical solutions: under draw two telescoping delivery pipes of formula storehouse pump, under comprising, draw formula storehouse pump and two telescoping delivery pipes, two telescoping delivery pipes are arranged on down and draw pump bottom, formula storehouse; Two telescoping delivery pipes are comprised of two flanges, delivery pipe outer tube, conduit liners pipe and feed pipe, delivery pipe outer tube and conduit liners pipe horizontal positioned and conduit liners pipe are arranged on delivery pipe outer tube inner side, feed pipe is positioned at two telescoping delivery pipes below, be communicated with conduit liners pipe, two flanges are arranged on respectively delivery pipe outer tube two ends.
The beneficial effect the utlity model has is:
1, improved the service life of time drawing formula storehouse pump delivery pipe.
The service life of 2, drawing formula storehouse pump under raising.
3, the utility model is carried for coal-fired boiler in thermal power plant dusting equipment strength, extensive in sector applications such as metallurgy, electric power, mines.
Accompanying drawing explanation
Fig. 1 is main cutaway view of the present utility model;
Fig. 2 draws formula storehouse pump front view under being;
In figure: flange 1, delivery pipe outer tube 2, conduit liners pipe 3, feed pipe 4, under draw formula storehouse pump 5, two telescoping delivery pipe 6.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is done into some explanation.
As shown in Figure 1 and Figure 2, draw formula storehouse pump 5 and two telescoping delivery pipe 6 under the utility model comprises, two telescoping delivery pipes 6 are arranged on down and draw pump 5 bottoms, formula storehouse; Two telescoping delivery pipes 6 are comprised of two flanges 1, delivery pipe outer tube 2, conduit liners pipe 3 and feed pipe 4, delivery pipe outer tube 2 and conduit liners pipe 3 horizontal positioned and conduit liners pipe 3 are arranged on delivery pipe outer tube 2 inner sides, feed pipe 4 is positioned at two telescoping delivery pipes 6 belows, be communicated with conduit liners pipe 3, two flanges 1 are arranged on respectively delivery pipe outer tube 2 two ends, one connects conveying source of the gas, and one connects discharge nozzle.
While instantly drawing formula storehouse pump 5 convey materials, the feed pipe 4 of material from two telescoping delivery pipes 6 enters conduit liners pipe 3, and material flange 1 from two telescoping delivery pipe 6 opposite sides under the promotion of carrying source of the gas is exported.Material rubs with conduit liners pipe 3 when carrying, cause 3 wearing and tearing of conduit liners pipe, when conduit liners pipe 3 is worn out, due to the outer delivery pipe outer tube 2 that is provided with of conduit liners pipe 3, so draw the normal conveying of formula storehouse pump 5 under not affecting, draw the service life of formula storehouse pump 5 under prolongation.
Claims (1)
