西安专业Concrete mixerMixing plant is mainly used for concrete engineering, the main purpose is to mix mixed concrete, also known as concrete mixing plant。HZS series commercial concrete mixing plant adopts the international popular modular rapid assembly structure, imported or domestic mixing host, double machine double control computer control mode, anti-noise, anti-dust pollution, environmental protection design,Concrete mixer图片It is a new generation of cement concrete mixing equipment, which is suitable for urban and rural commodity ready-mixed concrete, road and bridge, water conservancy, airport, port and other large infrastructure construction projects and places with large demand for concrete。Mixing station can be divided into single station and double station，As the name implies，Single station that each mixing station has a mixing host，The two-machine station has two mixing machines，Each mixing machine corresponds to a discharge port，Therefore, the double mixing station is 2 times the production capacity of the single mixing station，The two-machine mixing plant is named 2HZS ，For example, 2HZS25 refers to a two-machine mixing plant with a mixing capacity of 2*25=50 cubic meters/hour。

Concrete mixing station is mainly composed of material storage system,Concrete mixer图片Material weighing system, material conveying system, mixing system, powder storage system, powder conveying system, powder metering system, water and admixture metering system and control system and other ancillary facilities。Mixing machine Mixing machine according to its mixing mode is divided into forced mixing and self-falling mixing。Forced mixer is the mainstream used in mixing stations at home and abroad.专业Concrete mixerIt can mix a variety of concrete such as fluid, semi-dry hard and dry hard。The self-falling mixing machine mainly mixes liquid concrete, which is rarely used in mixing stations。The forced mixer is divided into spindle planetary mixer, single horizontal shaft mixer and double horizontal shaft mixer according to the structural form。Among them, the double horizontal shaft forced mixer has good comprehensive performance。Weighing system Material weighing system is a key component that affects the quality of concrete and the cost of concrete production, which is mainly divided into three parts: aggregate weighing, powder weighing and liquid weighing。Under normal circumstances, the mixing station below 20 cubic meters per hour adopts the superposition weighing method, that is, the aggregate (sand, stone) is weighed with a scale, the cement and fly ash are weighed with a scale, the water and the liquid admixture are respectively weighed, and then the liquid admixture is put into the water weighing bucket before mixing。In the mixing station of more than 50 cubic meters per hour, the method of independent weighing of each material is used, and all weighing is controlled by electronic scales and computers。The weighing accuracy of aggregate is ±2%, the weighing accuracy of cement, powder, water and admixture is ±1%。

Types of concrete mixing Concrete mixing is divided into two types: manual mixing and mechanical mixing manual mixing strive to act quickly when mixing，The stirring time starts when water is added，It should generally comply with the following provisions: when the volume of mixing is below 30L, the volume of mixing is 4~5min(minutes). When the volume of mixing is 30L--50L, the volume of mixing is 5~9min. When the volume of mixing is 51L--75L, the volume of mixing is 9~12min，According to test requirements，Do slump measurement or specimen forming immediately。西安专业Concrete mixerAll operations must be completed within 30 minutes from the beginning of adding water。Mechanical mixing first pre-mix once, that is, first shaper, so as not to affect the mix ratio during formal mixing。Start the mixer, add stones, cement, sand to the mixer in turn, dry mix evenly, and then add water slowly, all the feeding time does not exceed 2min, after all the water is added, continue mixing for 2min。The mixture is unloaded from the mixer, dumped on the mixing catch, and then manually mixed for 1~2min, slump measurement or specimen forming can be done。Concrete mixer图片All operations must be completed within 30 minutes from the beginning of adding water。

In the concrete production process,专业Concrete mixer图片Equipment cleaning and vehicle cleaning process will produce a lot of sewage wastewater。At the same time, direct emissions will also cause great harm to the environment。Therefore, the sewage transformation treatment system in concrete production will realize 100% recovery of its wastewater and achieve zero sewage discharge standards。Sewage treatment and renovation system mainly includes concrete transport team discharge chute, sand separator equipment, sewage settling tank, sewage tank agitator, clarification tank, transport pump, filter press, etc。The conventional system has a total of four sump tanks and three clarifier tanks。Each of the 4 sump ponds has a surface guardrail and agitator。And No. 1 pool, No. 2 pool, No. 3 sewage pool is equipped with mud type pump, No. 2 and No. 4 pool is designed with liquid level meter;3 clarifier tanks You each have a sewage type pump。The periodic uniform movement of the agitator in the tank ensures that the water quality in the tank is uniform。The various pools in the sewage treatment system need to be arranged in a certain order, and the overflow pipes are connected to each other at the lower part of the pool, and the pumps are connected to each other at the upper part。When the amount of water in the pool is insufficient, the pump can be used to transport water to maintain the stability of the water。If there is a lot of water in the pool, it will flow back through the overflow pipe provided in the pool, and the water quality will be clarified during the reflux process。In the concrete mixing station, there is a flow tank connected with the sewage tank to collect rainwater into the pool to ensure the cleanliness of the station and reduce the operating cost。The main station and the vehicle cleaning system are equipped with a special flow tank to divert the production sewage to the sewage tank for unified treatment。Through the guided transformation of the entire drainage in the concrete mixing station, the sewage in the mixing station is not drained, and the treated sewage is directly supplied to the mixing station for use and vehicle cleaning use after inspection.Concrete mixer图片The resulting slag can also be used as an added aggregate。Achieve zero discharge of sewage treatment。
