Belt type press series

Product introduction

LDD series strength of roller belt type press machine is my company in the long-term development of material mechanical dewatering equipment based on, combined with the domestic and foreign similar multiple industry the latest technology independently developed a new generation of material concentration, strong squeeze dewatering in various severe dehydration equipment. It successfully solved the problem of continuous heavy and highly dry mechanical dewatering of plant wet residue. The design of innovation: using multilevel strength of pinch roll extrusion dehydration can make wet residue dehydration after the cake moisture rate is extremely low, greatly reducing the energy consumption of the subsequent drying or washing and its application, economy and reliability are the domestic leading level, and has been used in a number of large enterprises at home and abroad.
Belt press applicable scope
LDD series strength of roller belt type press machine a variety of products widely used in plant root, stem, leaf and fruit after processing using surplus wet slag (or worse) material dehydration drying production, including lees, cassava dregs and sweet potato residue, tea dregs, corn residue, bagasse, Chinese medicine residue, apple pomace, wood pulp fiber, horseshoe residue, soybean dregs tank, slag, paste type mechanical filter press dewatering or washing dehydration.
Two, with the features of the belt press
Continuous production, processing capacity.
The dehydration effect is good, the filter cake moisture content is low.
Low energy consumption, low cost operation.
Advanced structural design, a wide range of application.
Net belt speed control and deviation rectification control system advanced technology, can ensure long-term stable operation.
Selection of quality materials and spare parts manufacturing.
Full automatic operation, easy operation and maintenance.
Three, belt press working principle
After wet slag refining (or solid-liquid mixture), through screw pump or continuous conveyor into the hopper (material bandwidth adjustable), and two annular filter with the drive roller driven by the screw feed roller uniform distribution, curved wedge entered recurved, initial pressure dehydration. Then enter the area of low pressure, pressure roller with a "L" type or water large extrusion, and ensure the water discharged from both sides, then enter the folder on the extrusion of high pressure zone, both inside and outside the filter belt around several groups of clamping diameter decreasing extrusion roller, a large amount of water is slowly out of strength, the filter cake can be formed the press, on the other hand, a filter belt shearing force S type winding caused by shaving the surface pressure, the belt tension under the action of the outer filter belt to make the material pressure a little water in the materials is due to direct press roll Gradually reduce the diameter, the filter belt material between the pressure gradually increased, a small amount of water continuously discharged. Material in large amounts of water by strong on the clip and squeezing discharge, and the receiving tank collecting and discharging, in the inside and outside of the filter strip was separated, with wear-resistant scraper device and filter with work on the surface of the dewatered cake Guo Zha scrape. Finally by high pressure solid cone convex type cleaning nozzle, forming cross sector hose constantly washing mesh belt, in order to maintain the sustained dehydration effect.
Four, with the main structure and characteristics of the belt press
The system consists of host (dehydration machine body) II air compressor (3) electrical control cabinet (4) network with clean water pump, feed and discharge assistance device. The main machine is composed of a machine frame, upper and lower driving rollers, a transmission device combined with a roller device, an upper and a lower filter screen, a Zhang Jin device, a correcting component, a distributing device, a gas control cabinet, a cleaning nozzle and a water tank. As follows:
1, the transmission motor: the use of the speed control of the reducer through the frequency converter, can achieve continuous and smooth speed regulation function.
2, mesh belt: made of high strength polyester nylon silk warp and weft knitting, with high strength, acid and alkali resistance, high temperature resistance, easy cleaning and stripping cake.
3, the clamp squeeze roller: using thickness 12-15mm high-quality seamless steel pipe outsourcing natural rubber or silica gel, and size decreases, low pressure stainless steel L type pressure and unique structure reasonable, internal and external extrusion water can be through the guide slot discharge, all squeezed out of the water are with the running direction of the filter cake opposite to ensure filter water back to the ceiling.
4, network with the correction: the use of close proximity sensor precision control network with offset, to ensure that the network is not more than 10mm.
5, a material distributing device: using spiral and rotating scraper is uniform and flat cloth to ensure all pressed cake moisture rate consistent, does not make the network zone on both sides of the moisture of material is high.

Six, before the start of the work to prepare and check items
1, check the host, auxiliary equipment (slurry pump, a filter screen cleaning pump, air compressor, conveyor) and water, electricity, gas, a connecting pipeline, valve installation whether conform to requirements, whether the omission, whether fastening etc..
2, cleaning the site and the host on the debris, especially the host filter can not be abandoned on any debris, to prevent the operation of the filter when the squeeze and damaged.
