Description
Technical field
The utility model patent relates to a kind of granule materials hot-press forming device field, particularly is rich in the hot-press forming device after water brown coal drying is handled.The capillary pipe structure of for a change dry back brown coal reduces in case be in again in malaria or the water, can absorb the moisture that loses rapidly and carries out the equipment of hot-forming usefulness.
Background technology
Exploitation moisture is directly used in burning up to the brown coal of 15wt%～50wt%, not only boiler combustion instability, and also efficient is also very low.High-moisture makes these coals to use in the locality, can not long-distance transportation and be used for the gasifying process of high added value, thus, greatly limited the exploitation scale of coal.Therefore the moisture brown coal of height being carried out drying is very important.
The brown coal that are rich in water also must adopt hot-forming technology and equipment to carry out following process after drying.Could improve the comprehensive use value of brown coal, particularly the Coal Chemical Industry as raw material is worth.In recent years, countries such as Australia, Germany, Greece, the U.S. are all at drying technology and the equipment of research and development at brown coal.Some has entered commercialized running, therefore develops advanced brown coal drying former, and for the market competitiveness that improves brown coal, it is significant to reduce cost.
Summary of the invention
The purpose of the utility model patent provides a kind of hot-forming key equipment, is specially adapted to be rich in the hot-forming processing after water brown coal drying is handled.Moulded coal after moulding can satisfy the technological requirement of long-distance transportation, boiler combustion or Coal Chemical Industry pure oxygen gasification.
The purpose of this utility model is achieved through the following technical solutions:
A kind of hot pressing roll squeezer (referring to accompanying drawing 1) that is rich in after water brown coal drying is handled is mainly by charging aperture and coal grain distributor 1; Coal grain prepressing device 2; Positive movement roll shaft 3; Counter motion roll shaft 4, hydraulic speed regulating device 5; Roll-in hydraulic means 6; Hot-forming roll squeezer bearing 7; Moulded coal outlet 8; Material mold 9; Hot-forming roll squeezer motor 10 is formed by combining; Charging aperture and coal grain distributor 1 link to each other with coal grain prepressing device 2, material mold 9 is installed in respectively on positive movement roll shaft 3 and the counter motion roll shaft 4, positive movement roll shaft 3 is fixing, counter motion roll shaft 4 is by the spacing of roll-in hydraulic means 6 adjustings with positive movement roll shaft 3, high pressure roll press motor 10 is connected with the motion roll shaft, hydraulic speed regulating device 5 is connected with counter motion roll shaft 4, is used to regulate rotating speed.
Described high pressure roll press, positive movement roll shaft 3 is fixing, and counter motion roll shaft 4 can slide, and counter motion roll shaft 4 passes through the spacing of hydraulic means 6 adjustings and positive movement roll shaft 3 at 0.5-3mm, shift length≤2.5mm, the minimum range between two rollers should remain on≤the 0.5mm scope in.
With the utility model hot pressing roll squeezer the hot press forming technology step that is rich in after water brown coal drying is handled is comprised:
(1) after drying be rich in the water brown coal, its water content is at 8wt%-15wt%, granularity≤6.3mm further is crushed to≤2mm, as the pan feeding raw material of hot-forming roll squeezer;
(2) adopt brown coal to need not to add the bonding agent hot press forming technology, with the compression moulding of hot pressing roll squeezer, the brown coal raw material is through the roller of two relative rotary motion of hot pressing roll squeezer, under certain temperature, moisture, granularity and high pressure, material is sent in the mould, material is pressed into desired shape there, the size of material mold can change as required, the brown coal temperature of moulding compacting is 60-90 ℃, moulding compacting brown coal group pressure is 400-8000kN, the pressure 24-75KN/cm of unit length group, brown coal are pressed into the 20*32*38mm shape.
Described brown coal need not to add the bonding agent hot press forming technology, because a large amount of moisture pores are arranged in the brown coal, and contained humidity is called interior water in the pore, through adopting steam tubular type contact drying technology, the moisture of the overwhelming majority is evaporated, and water is as bonding agent in the small part.According to the type of brown coal and the requirement of moulding, keep certain interior water, its water content is at 8wt%-15wt%.Pore is by conquassation and destruction during moulding, and then the space of filling coal intergranular, presents interactional molecular separating force, strengthened the contact of coal intergranular and moulding.
Described brown coal hot press forming technology, brown coal can compress granular material, compacting under the pressure of two rollers.Granular material enters roll shaft from the upper end, begins to form thrust from certain specific angle, and in the moment that is about to reach minimum slit between two rollers, pressure reaches maximum, and then pressure reduces rapidly.Can be with the granular material volume compression to original 30%-50%, density is brought up to 1.5-3 times of original granular material density.Brown coal pore after the moulding compacting is destructurized, so the phenomenon that absorbs water again greatly reduces.It is low that this moulded coal has moisture, and calorific value improves 40%-50%, and the spontaneous combustion probability reduces in a large number, is convenient to transportation and reduces cost.
The advantage of the utility model patent:
The utility model patent need not to add the bonding agent hot press forming technology with the hot pressing roll squeezer to being rich in to adopt after water brown coal drying is handled, and makes whole forming process safety, reliable, non-pollution discharge.Brown coal caloric value after hot-forming increases, and has improved the fuel factor of brown coal dynamic combustions, and coal gasification is saved the energy to the specific (special) requirements of raw material.
Brown coal moisture after hot-forming is removed in a large number, reduce in a large number in the space, the mechanical strength of brown coal obviously strengthens, ature of coal density increases, be convenient to transportation, reduced the transport power expense, make the utilization of brown coal not be subjected to the restriction of region, changed the producing coal area and now adopted the single utilization approach of existing burning, for the comprehensive utilization of brown coal is provided convenience.
Brown coal after hot-forming are easy-weathering not, can solve the spontaneous combustion of brown coal heap, prevents the wasting of resources, alleviates the environmental pollution that the dump burning brings, the storage life of improving brown coal.
The utility model patent hot-press forming device also is applicable to coal that other are rich in the water yield or other material forming, and hot-press forming device is rational in infrastructure, and mature and reliable is easy to make, construction is simple, processing ease, layout compactness, has favorable economic benefit.
