Specifically, the raw coal is milled to meet the requirements of complete gasification reaction of the Shell furnace and minimized power consumption of the milled coal, the particle size of the pulverized coal milled by the milling equipment also has certain size requirements, the raw coal is firstly crushed into particles with certain particle size through rough machining before the raw coal is milled, and then the rough-machined raw coal particles are finely processed into powder, and the milling component 2 provided by the invention belongs to equipment required by a fine machining process. When the coal grinding device works, raw coal with larger particles and crushed through rough processing is quantitatively put into the grinding component 2 each time, due to the difference of the hardness of different raw coal, when the grinding force given to the raw coal by the grinding component 2 is not enough to grind the raw coal in an initial state, the raw coal gives a reaction force to the grinding component 2 to enable the grinding component 2 to react with the pressure detection component 4 again, the pressure detection component 4 transmits a signal of the reaction force given by the grinding component 2 to the pressure adjusting component 3, the pressure adjusting component 3 can adjust the grinding pressure given to the raw coal by the grinding component 2 to enable the grinding pressure of the grinding component 2 to be enough to grind the raw coal so as to realize that the particle size of the raw coal is ground into the required particle size, the pulverized coal ground by the grinding component 2 is doped with pulverized coal with the particle size which is not within the particle size range of the pulverized coal to be required, and then the pulverized coal ground is screened again to obtain the pulverized coal with the required particle size, so that the pulverized coal can meet the requirements of complete gasification reaction of the Shell furnace and minimum power consumption of grinding the coal.
In the coal chemical industry, one of the advantages of the Shell furnace is that the requirement on the type of raw coal is low, so the grinding device provided by each embodiment of the invention is particularly adaptable, but it is clear to those skilled in the art that other types of coal chemical industry processes have the requirement on the type of raw coal, but the processes capable of being adapted to more than two types of raw coal are also available, and the grinding device provided by each embodiment of the invention can be also applied.
According to the embodiment of the invention, the pressure detection component 4 is arranged, so that the raw coal with different hardness milled by the milling component 2 can be sensed at any time, the pressure detection component 4 transmits the detected pressure change signal to the pressure adjusting component 3, and the pressure adjusting component 3 can adjust and control the milling pressure given to the raw coal by the milling component 2, so that different milling pressures can be better applied according to the different hardness of the raw coal for milling, and the particle size of the milled coal powder can be controlled to be within the required range on the basis of improving the milling efficiency of the raw coal.
Preferably, the grinding assembly 2 includes a first reciprocating mechanism 20 and a grinding roller 21, the first reciprocating mechanism 20 is disposed on the frame body 1, the pressure detecting assembly 4 includes an elastic assembly 40 and a pressure sensor 41 disposed on the frame body 1, the elastic assembly 40 includes a first elastic element 400 and a second elastic element 401, the grinding roller 21 includes a roller body and a connecting rod 210 disposed at two ends of the roller body, the first elastic element 400 is used for connecting the first reciprocating mechanism 20 and the connecting rod 210, the second elastic element 401 is directly connected with the first reciprocating mechanism 20, a grinding trough body 22 is further disposed on the frame body 1, and the first reciprocating mechanism 20 drives the grinding roller 21 to grind raw coal in the grinding trough body 22 in a reciprocating manner when in operation.
Preferably, the movement track of the first reciprocating mechanism 20 when driving the grinding roller 21 to move is in an arc-shaped structure or an approximate arc-shaped structure, the grinding groove body 22 is in an arc-shaped structure, and the curvature of the movement track of the arc-shaped structure is smaller than the curvature of the grinding groove body 22 in the arc-shaped structure, that is, in the grinding process, the gap between the grinding roller 21 and the grinding groove body 22 has a gradual change process which gradually decreases and then gradually increases, so that the grinding of the grinding roller 21 has a gradual pressurization process, and the grinding effect is improved.
Preferably, the milling groove body 22 is connected with the frame body 1 in a rolling manner, a rolling track of the milling groove body 22 is of an arc-shaped structure and is concentric with an arc-shaped movement track of the first reciprocating mechanism 20 driving the grinding roller 21 to reciprocate, and the grinding roller 21 drives the milling groove body 22 to reciprocate on the frame body 1 to sieve the milled raw coal when reciprocating.
Specifically, raw coal particles crushed through rough processing are placed into a grinding groove body 22, a first reciprocating mechanism 20 is started to drive a grinding roller 21 to reciprocate in the grinding groove body 22, the grinding roller 21 and the raw coal are influenced by friction force, the grinding roller 21 rotates, so that the first reciprocating mechanism 20 drives the grinding roller 21 to grind the raw coal back and forth, if the raw coal is high in hardness, the grinding pressure given to the raw coal by the original grinding roller 21 is insufficient to grind the raw coal, the raw coal acts on the grinding roller 21 in a reverse mode, the distance between the grinding roller 21 and the inner wall of the grinding groove body 22 is increased, the first elastic element 400 is compressed, the pressure sensor 41 detects the increase of the elasticity of the first elastic element 400 and transmits a signal to the pressure adjusting assembly 3, the pressure adjusting assembly 3 adjusts the distance between the grinding roller 21 and the inner wall of the grinding groove body 22 based on the signal, the two are close to each other, which is equivalent to applying pressure to the raw coal, and then the grinding roller 21 normally moves to grind the raw coal into powder for a plurality of times.
When the first reciprocating mechanism 20 drives the grinding roller 21 to reciprocate, and when the grinding roller 21 moves towards two ends of the movement track, because the curvature radian of the movement track of the circular arc structure is smaller than the curvature radian of the grinding groove body 22 of the circular arc structure, the distance between the grinding roller 21 and the inner wall of the grinding groove body 22 is closer and closer, the grinding roller 21 can extrude the inner wall of the grinding groove body 22 through the raw coal to be ground, so that the grinding groove body 22 gradually deviates from the center position of the rolling track where the center of gravity is located, the grinding groove body 22 with the deviated center of gravity tends to reset, and generates a reaction extrusion force to the raw coal, so that the raw coal is extruded by the grinding roller 21 and the grinding groove body 22 together, the grinding efficiency of the raw coal particles can be accelerated, and the grinding groove body 22 with the deviated center of gravity rolls on the frame body 1, one end of the grinding groove body far away from the grinding roller 21 tilts, and the raw coal in the grinding groove body 22 can slide towards the position where the grinding roller 21 is located, the effect of sieving the raw coal is formed, and the influence on the crushing effect and the crushing efficiency caused by the accumulation of the raw coal is avoided.
Further, a plurality of groups of sieve holes 220 are arranged on the grinding groove body 22 in parallel along the rolling track of the grinding groove body 22 on the frame body 1, a plurality of support rods 221 are arranged on the frame body 1 under the grinding groove body 22 in parallel along the rolling track of the grinding groove body 22, a plurality of material guide rods 222 are arranged on the support rods 221 in parallel, each group of sieve holes 220 corresponds to the plurality of material guide rods 222 on each support rod 221 one by one, and rolling bodies are arranged at the end parts of the material guide rods 222 in a rolling manner.
Specifically, the grinding groove body 22 with the deviated gravity center rolls on the frame body 1, one end of the grinding groove body far away from the grinding roller 21 tilts, raw coal in the grinding groove body 22 slides towards the position where the grinding roller 21 is located, a screening effect is formed on the raw coal, the screened raw coal mixed with some coal powder with proper particle size and the coal powder with the particle size smaller than the required particle size can be screened out from the screen holes 220, so that some coal powder with proper particle size can be screened out in time, secondary grinding can be avoided, the contact area and contact opportunity between the raw coal which is not ground into proper particle size and the inner walls of the grinding roller 21 and the grinding groove body 22 are increased, and the grinding efficiency of the raw coal can be effectively improved.
When the grinding roller 21 moves in the grinding groove body 22, the raw coal is extruded, the particle size of crushed particles of the extruded raw coal is just suitable for or slightly larger than the size of the sieve pore 220, and the crushed particles are clamped in the sieve pore 220 under the extrusion of the grinding roller 21, so that the efficiency of sieving coal powder by the sieve pore 220 is influenced, the invention arranges a plurality of material guide rods 222 which are one-to-one corresponding to the sieve pore 220 on the rolling track of the grinding groove body 22, and in the rolling stroke of the grinding groove body 22, the rolling body at the end part of the material guide rod 222 is extruded by the outer wall of the grinding groove body 22 to axially reciprocate (the material guide rod 222 is connected on the frame body 1 through a damping mechanism so that the material guide rod 222 and the rolling body have an axial moving amplitude as a whole, or the bottom of the rolling body is abutted against a spring so that the rolling body can have an axial moving amplitude, the movement amplitude is small so as to only enter the sieve holes), and the rolling bodies can temporarily block the sieve holes 220 and are positioned at the positions of the grinding rollers 21 when being extruded into the sieve holes 220, thereby avoiding the occurrence of material jamming caused by the extrusion of the grinding rollers 21, because the material blocking is compact and not easy to clean under the condition, a part of the rolling body entering the sieve pore 220 due to extrusion deformation can generate a certain ejection effect on raw coal particles blocked in the sieve pore 220 when the coal powder is sieved, the efficiency of sieving the coal powder by the sieve pore 220 is prevented from being influenced, the grinding groove body 22 is subjected to huge extrusion acting force during operation, and the part of the grinding groove body 22 provided with the sieve pore 220 has no supporting effect on the frame body 1, in the whole movement process, the material guiding rod 222 and the rolling bodies realize the integral support of the milling groove body 22, so that the stress of the milling groove body 22 can be balanced, and the service life of the milling groove body can be prolonged.
Further, a particle size control piece 42 is arranged on the connecting rod 210, an arc-shaped slideway 43 is arranged on the grinding groove body 22, the particle size control piece 42 is in sliding contact with the arc-shaped slideway 43, and the particle size control piece 42 is used for controlling the distance between the grinding roller 21 and the inner wall of the grinding groove body 22.
