Description

Vertical shaft concrete cement discharging system

Technical Field

The utility model relates to a grey system under vertical pit shaft concrete.

Background

At present, the domestic vertical shaft concrete construction is mainly a bottom-dump bucket, and the defects of the bottom-dump bucket are that the time for waiting for stirring and discharging ash is long, the single-feed circulation progress is slow, the concrete construction quality is low, and the construction cost is high. Particularly, the construction method has the defects that the construction method adopts CF 90-grade high-strength concrete, has large concrete pouring amount and high quality requirement in vertical shaft construction with inner and outer wall thicknesses (2.4 m), and is particularly outstanding. Therefore, the technical problem to be solved at present is to design a high-efficiency, convenient and quick concrete cement discharging system for a vertical shaft, which has the advantages of high single-feed circulation progress, high concrete construction quality and low construction cost and can ensure safe production.

Disclosure of Invention

The utility model aims to solve the technical problem that a technical ability guarantees that the single advance circulation progress is fast, concrete construction high quality, construction cost are low, can guarantee again that high efficiency, convenient and fast's of safety in production vertical shaft concrete goes down grey system, is the technical problem that needs to solve at present.

The technical proposal of the utility model for solving the technical problem is that:

the concrete ash discharging system for the vertical shaft comprises a stirrer and a bottom-discharge bucket, wherein a storage chute is arranged at a feed opening of the stirrer, a self-flow ash discharging groove and a rotary chute are arranged between the storage chute and the bottom-discharge bucket, and an ash blocking plate driven by an air cylinder and controlled by a pneumatic hydraulic valve is arranged on the self-flow ash discharging groove. The combination of the storage chute and the gravity flow type ash chute can store concrete and slide ash, ensures that the bucket can be filled immediately after the bottom-discharge bucket is lifted, saves the time for waiting for stirring the concrete, and improves the construction efficiency. The self-flow ash chute and the rotary chute can directly discharge ash into the bottom-discharge bucket, thereby simplifying the construction procedure. Can freely switch between two well-buckets through rotatory chute device to realize quick convenient ash discharging mode.

As an optimized proposal of the utility model, the mixer also comprises a batching and feeding system which is composed of a sand batching hopper, a stone batching hopper, a hopper track and a hopper.

As an optimized proposal of the utility model, the two mixers are symmetrically arranged relative to the storage chute. The stirrer is a JS1000 type stirrer.

Compared with the prior art, the utility model discloses very big improvement concreting blanking speed, every mould pouring time shortens to 6~6.5 hours by prior art's 8~9 hours, very big reduction single cycle time, the effectual efficiency of construction that has improved. The consumption of equipment materials and the time for overhauling and maintaining can be avoided. The concrete pouring construction quality can be effectively improved, and the concrete pouring construction method is suitable for C30-CF 90 common concrete and steel fiber high-grade concrete. The degree of mechanized operation is high, intensity of labour is little, and artifical input is few, effectively reduce cost.

Detailed Description

As shown in the figure, the vertical shaft concrete ash discharging system comprises a stirrer 1 and a bottom-dump bucket 7, wherein a storage chute 2 is arranged at a feed opening of the stirrer 1, a self-flow ash chute 3 and a rotary chute 6 are arranged between the storage chute 2 and the bottom-dump bucket 7, and an ash blocking plate 5 driven by an air cylinder and controlled by a pneumatic hydraulic valve 4 is arranged on the self-flow ash chute 3.

The mixer 1 also comprises a batching and feeding system consisting of a sand and stone batching hopper 8, a hopper track 9 and a hopper 10.

The two stirring machines 1 are symmetrically arranged relative to the material storage chute 2.

Manufacturing a concrete storage chute:

the storage chute is made of a pattern steel plate with the thickness of 5mm, is integrally welded in a seamless mode and is welded at the bottom of a feeding hole of the stirring machine. The concrete material of 1 time of stirring can be stored to 2 in the storage chute after reforming transform, 1 also can store the concrete material of 1 time of stirring in the mixer, after bottom discharge formula well-bucket 7 fell the well head, at first unload to well-bucket 7 with 2 concrete in the storage chute in, unload to well-bucket 7 with the concrete of 1 in two mixers in proper order again, direct disposable well-bucket that fills up, the time of waiting to stir 1 time has been reduced, the time of 1 time of stirring (including the material loading) generally is 5 minutes, 26 well-buckets of concrete need to be pour to a section height of the vice vertical shaft pit shaft in new huge Dong, 130 minutes can be practiced thrift to concrete so every section height poured, the regular cycle progress is 25 moulds every month, just so can save 54.2 hours every month, the effectual efficiency of construction that has improved.

Manufacturing a self-flowing ash chute:

the gravity flow ash chute 3 is formed by bending a 5mm steel plate into a U shape and welding, and the lower part of the gravity flow ash chute is provided with a pneumatic hydraulic ash blocking valve 4. The ash chute 3 is installed and connected to the bottom of the storage tank 2 of the feed opening of the stirrer, and the gradient of the ash chute 3 is determined according to the distance from the installation height of the stirrer 1 to the wellhead bottom-dump bucket 7 (the height of the originally designed stirring station is 4m, and the height of the improved stirring station is 6.3 m). The bottom-dump bucket 7 falls on the well cover door, and the gravity flow type ash chute 3 utilizes the fall gradient between the stirring station and the bucket, thereby generating the autonomous fluidity and rapidly conveying the stirred concrete to the bottom-dump bucket 7. After the bucket is full, a stirring driver opens a pneumatic hydraulic valve 4 to open a switch to drop an ash baffle 5, so that ash is prevented from flowing.

Manufacturing a rotary chute:

the lower part of the gravity flow ash chute 3 is provided with a rotary chute 6 device which can freely switch between the two lifting buckets for loading, and is simple, convenient and quick.
