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。成都专业Simple mixing plantAll 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。Simple mixing plant图片All operations must be completed within 30 minutes from the beginning of adding water。

1, mixing system Mixing system by motor, reducer, a pair of open gear and chain drive, mixing device and mixing tank composition。The motor is mounted on the end face of the reducer, and drives the two horizontally configured mixing shafts to reverse equal speed rotation respectively through a pair of open gears and chain drives。The mixing shaft is supported in the groove mixing tank formed by welding steel plate。Each stirring shaft is equipped with six stirring blades, and the mixture in the stirring tank is driven by the stirring blades to make "mutual cutting and turning" operation and alternately move according to the spiral trajectory。The combination of horizontal eddy current and vertical reverse flow agitation makes the material get rapid and strong agitation。专业Simple mixing plant图片Due to the small linear speed of the perimeter of the mixing blade, the energy consumption of the mixing concrete, the wear of the blade and the lining plate are much smaller than other mixers。The shape, quantity and arrangement of stirring blades are the main factors affecting the mixing quality and technical performance of the mixer。A special floating sealing device is provided for the connection of the mixing shaft and the two ends of the mixing tank。The sealing device is also equipped with a special oil feeder, the main mixing shaft rotates, and the oil feeder automatically supplies oil to each sealing part to ensure the lubrication of the mixing shaft shaft end seal and support。2. Feeding system Feeding system is composed of hoist, feeding rack, hopper, etc。When loading，Load the mixture to be stirred into the hopper，The starting winch motor drives the drum to rotate through the reducer，When the hoisting wire rope pulls the hopper up to a certain height along the loading rack track，A pair of rollers on the bottom of the hopper enter the feeder level fork，The door opens automatically，Feed the material into the mixing tank。3. The discharge device is equipped with a discharge door at two arcs on one side of the cylinder, which can be rotated around the horizontal axis to open and close the eyes through an electric push rod。The horizontal shafting at both ends is supported on a support seat fixed to the bottom of the mixing tank。The length of the discharge door is slightly shorter than that of the tank. When the discharge door is opened, most of the mix is discharged by its own weight, and the residual mix is forced out by the mixing blade, so that the discharge is clean and fast without segregation。The joints of the discharge door and the mixing tank are sealed with wear-resistant rubber strips, and the backing plate on the support seat can be adjusted to ensure the sealing after wear。4、 Simple mixing plant图片Water supply system The water supply system is made of unipolar centrifugal pump and quantitative principle。Under the guise of adjusting the pointer on the water tank dial, different amounts of water can be supplied。The two spray pipes are located directly above the two mixing shafts。The inlet and outlet of the water tank is controlled by the joystick of the three-way valve。When the water tank is supplied, the three-way valve cuts off the water discharge pipe, and the water inlet pipe is closed when the water tank is discharged。5, rack The rack is composed of bottom frame, legs, railings, platform, ladder, etc。Except for the railing, the rest are connected by bolts to the rack, and the railing is inserted into the socket hole on the rack。6. Electrical system。

In the production process of concrete mixing station,专业Simple mixing plant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 after inspection, and the waste residue generated can also be used as added aggregate。专业Simple mixing plantAchieve zero discharge of sewage treatment。
