Abstract

The utility model discloses a coarse particle separator applied to environment-friendly sewage treatment. A screw lifting mechanism of the coarse particle separator adopts a structure which is provided with a belt-type helical blade (5), a tubular shaft (6), a blade supporting frame (3), a special underwater rolling bearing component (3), a seated rolling bearing (9), and a big chain wheel (9) in a segmental form, so that the hard wear between the coarse particle separator and a U-shaped groove is avoided. The coarse particle separator increases the lifting efficiency of sludge, lightens the lifting resistance, reduces the power consumption of devices, and facilitates the maintenance and parts replacement; besides, a drive mechanism adopts chain drive so that the drive is smooth and reliable.

Description

Novel coarse granule seperator

Technical field

The utility model relates in a kind of environmental protection water treatment system, is applicable to that steel or concrete prefabricated coarse granule separate the novel coarse granule seperator of tank.

Background technology

At present, the problem of existing coarse granule seperator existence:

1, screw lift adopts an entity spiral blade, and the effect along the blade recirculation water during owing to lifting reduces lifting efficient, and blade is non-dismountable, and whole conveyor screw is scrapped behind blade wear, and the equipment use cost is big.

2, screw lift adopts no shaft belt type helical blade, and blade contacts with U-lag and forms the hard grind damage, and power consumption is big, influences the equipment bulk life time.

3, sliding bearing is adopted in spiral central siphon lower end, and the life-span easy to wear is low) or groove is usherd to seat outward, and (easily reveal maintenance bothers bearings.

4, motor reducer direct connection transmission, the big processing installation requirement of support height, poor to adaptability for working condition.

The utility model content

The purpose of this utility model is can effectively overcome above-mentioned four shortcomings of existing type by a kind of novel coarse granule seperator of design.Promote spiral and adopt segmentation that belt helical blade structure is installed, recirculation water can reflux from the space between blade and the tubular axis when coarse granule was raised, and alleviated along the blade recirculation water promoting the effect that rewinds of particle; Blade wear can dismounting and change after to a certain degree, and expense is low, has prolonged spirochetal service life, has reduced the working service cost of equipment; Employing has axle construction and two end supports to make blade and cell body avoid contacting the hard grind wiping, improves the equipment bulk life time relatively; Employing has that rolling bearing assembly supports as spirochetal lower end in the water of mechanical seal, do not exist cell body to reveal or the big problem of lower end spindle nose skimming wear amount, rolling bearing assembly is installed in the concave notches on the separating tank bottom bracket in the dedicated water, maintenance can be mentioned in the conveyor screw lower end, and it is easy to maintenance to change part; The cycloid speed reducer that employing is installed in the translator on the hinge type driving support seat drives the mode that conveyor screw rotates by chain wheel set, makes stable drive reliable, and the reductor support is little, and installation and maintenance are convenient, and are strong to applying working condition adaptability.

The utility model is achieved in that design is a kind of and forms hoisting mechanism by what the belt helical blade was installed in segmentation by usher to seat rolling bearing assembly etc. of rolling bearing assembly, upper end in the water of axle conveyor screw, band mechanical seal, chain wheel set, hinge type driving support seat, cycloid speed reducer, cuts off the novel coarse granule seperator of composition transmission mechanism such as guard pin.The belt helical blade is by the circumferential sectors manufacturing, be connected with bolt with the blade bracing frame that is welded on the tubular axis by each position on certain helix, form continuous hurricane band, the tubular axis lower end is connected with rolling bearing assembly flange in the dedicated water, rolling bearing assembly is installed in and makes the bearing block location in the concave notches on the separating tank bottom bracket in the dedicated water, the tubular axis upper end is connected with hinge wheel with safe break pin and by the roller bearings of usheing to seat, the cycloid speed reducer that is installed in the translator on the hinge type driving support seat drives conveyor screw by chain wheel set and rotates and upgrades deposited particles in the separating tank.

The specific embodiment

Describe detail and the working condition that the utility model proposes in detail below in conjunction with Figure of description.

Shown in Figure 1, the coarse granule seperator tilts to be installed in the U-lag of separating tank bottom, rolling bearing assembly (3) is installed in the concave notches on the separating tank bottom bracket in the dedicated water of conveyor screw tubular axis (6) lower end, conveyor screw tubular axis (6) upper end exceeds its axle head of water surface certain distance and supports the location by the top rolling bearing (9) of usheing to seat, keeping certain interval to avoid hard between helical blade and the U-lag contacts, hinge wheel (7) is connected with the tubular axis upper flanges with safe break pin (8), usher to seat rolling bearing (9) and motor reducer (12) of top all is installed on the hinge type driving support seat (10), and motor reducer (10) drives conveyor screw by chain wheel set and rotates and upgrades deposited particles in the separating tank.The heavy mud of particle moves until mud mouth on the promotion lower edge of ribbon blade (5) U-lag bottom in the lifting process, and the recirculation water major part can reflux from the space between blade (5) and the tubular axis (6).

Promote screw mechanism as shown in Figure 2, rolling bearing assembly in the dedicated water (3) is with client link under form of flanges and the central siphon (6), central siphon (6) upper end spindle nose is installed in the top rolling bearing (9) of usheing to seat and goes up and axial location, belt helical blade (5) is pressed quarter turn segmentation manufacturing, be connected with bolt with the blade bracing frame (4) that is welded on the tubular axis (6) by each position on certain helix, form continuous hurricane band, hinge wheel (7) is connected with tubular axis (6) upper flanges with safe break pin (8).

Transmission mechanism as shown in Figure 3, usher to seat rolling bearing (9) and motor reducer (12) of top all is installed on the hinge type driving support seat (10), driving support seat (10) is installed on the plant bottom case (11) by double-strand chain, and entire equipment can be mentioned around hinge axis, is convenient to maintenance maintenance.
