HZS25 concrete mixing plant is a semi-automatic concrete mixing machine composed of feeding, batching, mixing, electrical control and steel structure components. Hongbin Company has made special improvements after detailed investigation and research on the market, and combined with current domestic R&D of foreign advanced technology. The structure is simple, the construction is convenient, and the disassembly is convenient. It is suitable for the needs of customers. It is suitable for small-scale construction sites, prefabricated parts factories and commercial concrete production plants. It is more suitable for railways, highways and other mobile concrete supplies with strong mobility. Features.
◆25 mixing station adopts JS500 double-horizontal shaft forced mixing main engine, which has strong power, short mixing time, good mixing quality, low operating noise, reasonable structure design, and convenient operation and maintenance.
◆It can be used to mix various concretes with dry hardness, fluidity, lightweight aggregate concrete and other proportions, as well as various types of mortar.
Sand and gravel batching system:
◆The batching machine at station 25 is PLD800, which is composed of feeding device, weighing system, conveying device, electrical control system, etc.
◆According to actual needs, it can be equipped with a 2-cell batching machine or a 3-cell batching machine.
◆The weighing system of the PLD800 batching machine adopts a lever and an electronic sensor to make the measurement more accurate and fast.
◆The aggregate conveying system of the 25 mixing station adopts the lifting bucket conveying method, which has the advantage of occupying a small space and saving land resources.
◆Sand and gravel aggregates are conveyed to the weighing system by the belt conveyor, and then conveyed to the lifting bucket of the mixing host after weighing.
◆The batching and operation process of aggregate is: batching machine silo→weighing hopper→mixer lifting bucket→mixing host.
◆The metering system of 25 mixing station is composed of water scale, admixture scale, powder scale and aggregate scale.
◆The aggregate and powder are weighed electronically. The structure of the sand-gravel aggregate scale includes a belt scale and a bucket scale; the powder scale adopts a bucket scale;
◆Water and additives are measured by electronic scales. The water meter is discharged by a water pump, and the admixture is measured in a hanging type with an electronic sensor.
Powder silo and conveying system:
◆The powder storage bin and conveying system are composed of cement bin and screw conveyor.
◆The running process is: powder silo → screw conveyor → powder weighing hopper → mixing host.
1. Cement warehouse
◆The cement silo is a steel structure, consisting of a cylinder, a bracket, a valve, an arch breaking device, a feed pipe, and a dust collector on the roof of the silo.
◆In order to prevent the powder from arching, a blower arch breaking device is installed at the bottom cone of the silo, and a solenoid valve is used to control the release of compressed air for powder arch breaking.
◆The powder is fed into the silo through the feed pipe by air pressure, and the pressure gas generated in the silo is discharged through the dust collector on the top of the silo.
2. Screw conveyor
◆Screw conveyor is responsible for conveying the powder in the powder silo to the conveying equipment of the powder metering hopper.
◆It is mainly composed of pipe body, inlet and outlet pipe, screw shaft, intermediate support seat, power transmission device, etc., with high transmission rate, good sealing performance, no dust pollution, and can be assembled in sections for easy transportation.
Electrical control system:
◆The control system of 25 mixing station is simple to operate and easy to master. Using high-precision batching control components, the batching is stable, the performance is reliable, the error is effectively controlled, the manual control and the automatic control are integrated, and the report data can be stored and printed. It can also be equipped with a monitoring system, the interface is intuitive, and the on-site work flow can be observed clearly and accurately.
