When building concrete mixing plant, how to reduce dust and noise pollution is the concern of each manufacturer, the following is to say about this issue.
Concrete mixing plant around the dust should pay attention to the following two points
1, accurate planning, placement and reasonable selection of dust removal equipment. Install the dust removal device directly on the inclined belt head cover. All the air ducts are also connected to the inclined belt hood, providing space for the dust blown down by the air ducts to settle, and reducing the amount of dust directly into the dust removal equipment is functional. Then a pneumatic butterfly valve actively controlled by the operating system of the mixing plant is installed at the lower mouth of the dust collection hopper of the dust removal equipment.

2, should carefully check and maintain the dust removal equipment. The control of the dust removal vibrator of the silo dust removal equipment is very important, and the customers of the broad concrete mixing plant usually do not know its importance, until the dust removal function is found to be poor, the initial ash of the safety relief valve, the dust removal equipment is now filled with dust, and at this time, you want to initiate the dust on the vibrator filter element, usually it is too late, the base does not function. Therefore, each shift must check whether the dust collection pipe is not dust, because the non-vertical dust collection pipe is and easy to block. Be punctual to check the dust accumulation of the filter element of the dust removal equipment, and if necessary, disassemble and clean the filter element.

Concrete mixing plant noise treatment method
First, the use of whole station package
Concrete mixing plant packaging is the whole station of all mixing plant equipment packaging, the host packaging data selection of soundproof board, soundproof board to choose a better, do not seek cheap, if this aspect of the design is not very understand, you can consult the relevant manufacturers and technicians, close the material yard selection of hollow bricks for sound insulation can reduce the noise to a minimum.

Second, the use of new concrete mixer
The noise source of concrete mixing station is mainly from the concrete mixing station concrete mixing host, the new concrete mixing host can effectively reduce the noise produced by the concrete mixing station.
1, the production accuracy of the forward concrete mixer bin: This paper discusses a set of perfect processing technology scheme. The forward concrete mixing main machine bin system is accurate, so that the open space between the lining plate of the bin body and the mixing blade can reach below 0.5mm when the installation is made, so as to prevent the noise easily caused by the stone when the open space is too large, and the parallel degree of the two mixing axes of the special boring machine is selected to reduce the noise and then the smoothness of the forward transmission system. In the production of concrete mixers, Lianhua Machinery has high-end and perfect processing equipment, and has made a number of improvements in design to ensure that the mixer reduces noise during the production process and is 10% higher than the performance index of similar equipment efficiency.
2, the development of new concrete mixer reducer: The previous mixer with the reducer in accordance with the construction machinery specifications of low precision, loud noise, has been unable to meet the needs of the city's commercial concrete mixing station, in this choice of cross-industry plan, the automotive industry reducer planning idea and mixing station, the use of spiral arc umbrella tooth right Angle transmission, forward tooth shape production accuracy, tooth shape surface nitriding treatment, The speed reducer of this new mixer will work smoothly and with low noise.

Third, air path noise reduction
Many of the cylinders used in the concrete mixing plant are used as implementation components, and the impact is large and the noise is high at the end of the stroke. The gas-liquid contact buffer cylinder is introduced to the hydraulic buffer at the end of the stroke to reduce the noise.
Of course, for dust removal and noise reduction measures, through continuous exploration and trial, there are more methods. But on the whole, it is also necessary to arrange according to the equipment and work needs of the site. Production enterprises in the pursuit of cost reduction at the same time, but can not ignore the long-term benefits, can not simply to reduce costs and only consider the price when buying equipment, do not consider the quality and after-sales, if that is really the case, the later suffered losses must be their own. Therefore, when choosing the concrete mixing plant manufacturer, priority should be given to such an old enterprise as Lianhua Machinery, and it will be decided after comparison.
