Embodiment Construction

[0021] specific implementation plan

[0022] As shown in Figure 1, the overall structure is: a 4 kW variable frequency speed regulating motor with adjustable speed to meet the PLC control of different working systems; Resistance; c coupling adopts nylon column pin connection; d automatic air lock feeder, which is the core technology of the present invention.

[0023] The product of the present invention will be further described in detail below in conjunction with the accompanying drawings. The half-coupling 9 is connected with the nylon pin of the half-coupling of the cycloidal pinwheel reducer. This figure has been omitted. The shaft 9 is connected, the two ends of the bearing 10 are provided with seals, the inner side of the transparent cover 11 is the bearing frame oil seal 6, the inner side of the bearing 10 is a carbon fiber packing seal 26, the bearing seat is supported by two round end faces 3, and the bolts 1 and 2 connect the round The connection between the end fac...

Abstract

The invention relates to an automatic gas lock feeder which can transmit powder pneumatically, wherein eight rectangle bin blades form a blade wheel as a feeding transmitter, two circumferences and two axial side faces of the blade wheel are respectively sealed externally via a blade wheel end face sealing ring and a blade wheel axial face sealing pile, two end faces of the bearing use oil seal via a carbon fiber wheel and a skeleton, to externally seal the blade at six directions. The invention uses external seal technique to provide forward compensation spaces to all seals, and arranges a compression air room at the back of the seals, uses pressure balance under the constant pressure of external compressed air to realize automatic compensation. The seal material mainly uses modified F4, to realize abrasion-resistant dynamic seal under different conditions, while the pressure resistance of the chamber of the blade wheel can reach 0.25MPa. The automatic gas lock feeder can be engaged with any one of six pneumatic transmission methods as dense-phase, dilute-phase or the like, with compact structure, small volume, high efficiency, gas-lock transmission, strong output force, long service life, and low operation and maintenance costs.

Description

technical field [0001] The invention relates to the technical field of powder material pneumatic conveying system equipment. Background technique [0002] Pneumatic conveying system is mainly divided into: warehouse pump conveying, screw pump conveying, impeller pump conveying. As the core component feeder of the impeller pump conveying system, the current products include: rotary feeder (rotary valve), electric air lock, material seal feeder, etc., which are used to control the return pressure in the warehouse to ensure continuous and balanced powder. Feed. The above-mentioned feeders all adopt the impeller internal seal form. The anti-reflux pressure is weak≯0.1MPa, and the seal wears quickly. The service time is about 700 hours, and the operating cost is high. The rigid seal of the seal is 40,000 yuan for a replacement seal. As far as the seal structure is concerned, one form adopts the impeller rib round The end face is inlaid with a sealing strip, and the dynamic sea...
