Abstract

A non-shaft helical pipe pneumatic conveyor consists of a pneumatic conveying pipe 1, a hopper 2, a helical blade 3, an arc cover plate 4, a semi-circular bottom slot 5, a cover plate bracket 6, an electric motor 7 and the like. The non-shaft helical pipe pneumatic conveyor is an important component part of absorbing-conveying type pneumatic conveying equipment, and has the advantages of large capacity, long-distance conveying, no dust flying, no leakage, smooth operation, low power consumption, extremely low maintenance and repair cost, and capability of conveying materials at any angles from horizontal direction to vertical direction.

Description

There is not axle helical pipe Pneumatic conveyer

Technical field

The utility model belongs to a kind of pipeline strength that is used for to be carried and not to have the device that a helical feed combines, and it is to inhale the important component part of sending the formula pneumatic transport equipment.

Background technology

Existing Pneumatic conveyer and conveyor screw all are not suitable for long distance and carry in the sandblast sector application, when Pneumatic conveyer uses separately, energy consumption is big, noise is big, fed distance has been grown back pipeline and has easily been stopped up, carry and abrasive material makes moist that afterwards latch up phenomenon is more serious at high capacity especially, conveyor screw commonly used has axle, when carrying, long distance couples together by more piece, often because decentraction, blade and cell body rub sassafras year in and year out, will be out of shape, damage, understand generation screens phenomenon, bearing meeting burning is overhauled very frequent.

Summary of the invention

The purpose of this utility model provide a kind of closed, do not twine, do not have dust from flying, do not have to reveal, and running steadily, and operational throughput is big, and consumption of power is low, the M R expense is extremely low, and can be from level to the vertical arbitrarily angled pipeline transporter of growing apart from mass transport.

Do not have a structure that the helical pipe strength is carried as shown in drawings, top is material-falling hopper, and the bottom is not for having axle helical feed and Pneumatic conveyer.The material of carrying falls into by hopper not to be had in the axle screw, makes it motion and acceleration, and material is swept along in the air-flow, enters the pneumatic carrier road again and carries out subsequent delivery.Carry source of the gas generally to provide by high pressure positive blower or roots blower.Since divide the mass transport of pipeline mainly not finish, and give the certain initial velocity of material by there being the axle helix transporting device, the strength delivery speed height of main line, loss of pressure is little, and selected high pressure positive blower or roots blower power also reduce thereupon, reach purpose of energy saving.

Technique effect of the present utility model be it have closed, do not twine, do not have dust from flying, do not have to reveal, and running steadily, and operational throughput is big, and consumption of power is low, the M R expense is extremely low, and can be from level to vertical arbitrarily angled advantage of carrying out the long distance conveying of material.

The specific embodiment

Embodiment: as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, it is made of Pneumatic conveying pipeline 1, hopper 2, helicallobe 3, curved cover plate 4, semicircle kerve 5, cover board support 6, electrical motor 7 and bottom land liner plate 8.The Shaftless spiral blade 3 that is arranged in semicircle kerve 5 is by electrical motor 7 driven rotary, and adjustable-speed will promote from the material of hopper 2 and quicken, and delivers to Pneumatic conveying pipeline 1, and the dust of kicking up is on a small quantity covered by curved cover plate 4, can not leak.Curved cover plate 4 and cover board support 6 are detachable.

Claims

1. there is not a helical pipe Pneumatic conveyer, it is made of Pneumatic conveying pipeline (1), hopper (2), helicallobe (3), curved cover plate (4), semicircle kerve (5), cover board support (6), electrical motor (7) and bottom land liner plate (8), it is characterized in that: the Shaftless spiral blade (3) that is arranged in semicircle kerve (5) is by electrical motor (7) driven rotary, adjustable-speed; Curved cover plate (4) and cover board support (6) are detachable.
