Dry mortar supporting equipment detailed introduction

Dry sand from the dryer, through the bucket elevator, into the dry sand roller screen or linear mm particles by the belt conveyor to the waste sand yard, qualified dry sand through the bucket elevator, into the sand tank to cool down for use, the sand tank is designed for two, can put a sand, can also put two grades of sand, dry sand through the gate valve automatically into the bucket elevator, lifting to the yellow sand buffer tank for use, the bucket elevator is equipped with fault detection devices, such as bucket The bucket elevator is equipped with a fault detection device, so that if the bucket elevator is bogged down and other faults occur, it can be stopped and alarmed. If two grades of sand are used, they can be reasonably distributed through the tee-trousers on the yellow sand buffer tank and enter the yellow sand buffer tank respectively. The dry sand in the buffer tank automatically enters the batching scale through the pneumatic gate valve for batching according to the proportional requirements of the mortar product, and the cement, coal ash and thickening powder are transported to the raw material tank for use through the pump truck. The dry-mixed mortar sets are transported by screw conveyor to the powder batching scale for batching, the added small materials are put into the manual feeding hopper for batching by manual weighing according to the proportional requirements of the mortar products, the materials that have been dosed are put into the mixer in order, the mixer is equipped with a pneumatic sampling port, after mixing, the finished materials are put into the finished product temporary storage bin in the lower part of the mixer for temporary storage, the The finished product 1 is fed into the bulk machine through a reversing valve and loaded into a tanker for transport to the site, 2 can be fed into the packaging machine storage bin by a screw conveyor through a reversing valve and packed for storage, 3 can also be fed into the finished product hoist through a reversing valve and lifted to the finished product bin for storage.

The mixing line is an independent control system with monitoring, printing and dosing all set up as an automated system. The system collects data from each actuating element on site in real time, automatically generates report data, calibrates formula system data and gives feedback on alarm fault points.

The loader shovels the wet sand into the hopper and conveys it through the belt conveyor to the three-cylinder dryer for drying. The HKSH three-cylinder dryer is an energy-saving dryer developed independently by our company with intellectual property rights, where the wet sand first enters the inner cylinder and is fully heated and dried through the internal lifting plate of the drum, and then enters the middle cylinder through the guide plate. The drying machine enters the discharge hopper, the soot and exhaust gas produced during the drying process is pumped into the bag dust collector by the induced draft fan to remove the dust, the temperature of the exhaust gas is monitored in real time by thermocouple, when the temperature is higher than 115 degrees Celsius, the thermocouple will feedback this temperature to the control centre, the control centre opens the cold air valve to mix in cold air to lower the temperature, when the temperature is lower than 90 degrees Celsius, the thermocouple will feedback the temperature value to the control centre and close the Cold air valve, then the smoke and exhaust gas through the pulse bag dust collector bag filtration, so that the dust and exhaust gas separation, dust gas by the dust collector after treatment and discharge, emissions in line with our country's standards, bag dust collected by the dust from the screw conveyor to the yellow sand bucket lifting machine into the sand tank, the whole set of sand drying line using PLC control, LCD, ready and technology research and development center_dry mortar machinery and equipment dry mortar equipment price site all The materials and mechanical movements are all on the man-machine operation interface, with dynamic display and realistic picture.

HK series dry mix mortar production line is a dry mix mortar production system independently developed by Haike Environmental Technology Engineering Research Market, with many advantages such as simple structure, moderate investment, energy saving, green environmental protection. As a new type of energy-saving and environment-friendly building material, dry-mix mortar has an important role in saving resources and improving the efficiency of comprehensive use of resources, and is being compulsorily promoted and applied by China's policy. The centre specialises in the research of mortar production formulations, production processes and matching equipment for different raw materials and technical requirements. As an example, the structure and process flow of a dry-mix mortar production plant with an annual output of 300,000 tonnes are described below.

The rotary combustion furnace uses coal, natural gas and diesel as the main fuel. The coal powder is shoveled into the hopper by the loader, transported to the coal mill through the screw conveyor, sprayed into the combustion chamber of the main engine through the metal hose nozzle, and ignited by the diesel fuel atomised by the oil gun. At the same time, the blower blows into the combustion chamber through the ring-shaped rotating duct of the back cover of the main engine, the wind rotates forward against the inner wall, and the high-temperature flue gas flow mixes strongly with the pulverised coal for combustion, the internal temperature of the furnace chamber can be monitored by thermocouples and fed back to the control centre, and the temperature can be adjusted by the size of the coal spraying volume of the coal mill. The heat released from the combustion of the fuel enters the dryer under the action of the induced draft fan.
