Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, for the embodiment of the present invention discloses a cement raw material deferrization system, which mainly comprises a workbench 11, an inclined chute 12, a portal frame 13, a guide post 14, a baffle 15, an electromagnet 16, a driving device 17, etc., wherein the main part of the deferrization system is the workbench 11, and is placed on the ground during use. The top surface of the working table 11 is an inclined surface, an inclined trough 12 is arranged on the inclined surface, the bottom surface of the inclined trough 12 is also an inclined surface, the inclined direction and the inclined angle of the inclined trough are consistent with those of the top surface of the working table 11, and cement raw materials flow in from the higher end and then flow out from the lower end in the working process.
The portal frame 13 is composed of two vertical beams and a cross beam, the two vertical beams are respectively fixed on two sides of the workbench 11, two ends of the cross beam are respectively fixedly connected on the adjacent vertical beams, and the cross beam is positioned above the workbench 11 and is vertical to the flowing direction of cement raw materials in the inclined material groove 12.
The guide post 14 is installed on the crossbeam of the portal frame 13, and the guide post is connected with the crossbeam of the portal frame 13 in a sliding manner and is vertically arranged, so that the guide post can do linear reciprocating motion in the vertical direction. A baffle plate 15 is fixed on one end of the guide post 14 close to the top surface of the working platform 11, and the baffle plate 15 can be driven by the guide post 14 to be inserted into the cement raw materials in the inclined material groove 12 or pulled out.
The surface of the baffle 15 which is in direct contact with the cement raw material flowing in the inclined material groove 12 is a front side surface, the surface opposite to the front side surface is a rear side surface, an electromagnet 16 is installed on the rear side surface, and the baffle 15 can play a role in protecting the electromagnet 16.
The action of baffle 15 in vertical direction is realized under drive arrangement's 17 drive, and drive arrangement's 17 both ends are connected with baffle 15 and the crossbeam of portal frame 13 respectively, drive baffle 15 through flexible and move in vertical direction.
In the production process, cement raw materials flow into the inclined trough 12 on the worktable 11 from the higher end and then contact the baffle plate 15, and due to interception by the baffle plate 15, the cement raw materials are accumulated in front of the baffle plate 15 and pass over the baffle plate, and the baffle plate 15 and the electromagnet 16 are buried by the continuously flowing cement raw materials. The electromagnet 16 is electrified to generate a magnetic field, so that iron impurities in the cement raw materials are absorbed and prevented from entering the rear processing equipment.
In this process, cement raw meal can directly strike on baffle 15, in order to reduce the resistance that baffle 15 received, improves the velocity of flow of cement raw meal simultaneously, changes baffle 15 into the slope, and specific slope mode is that the one end that oblique silo 12 was kept away from to baffle 15 inclines backward, and when baffle 15 contacted with cement raw meal, baffle 15 can exert an ascending thrust to it for its speed of overflowing baffle 15.
Referring to fig. 3, since the production process is continuously performed and the baffle 15 is gradually worn, a wear-resistant layer 151 is additionally provided on the front side surface of the baffle 15, the wear-resistant layer 151 may be a diamond coating or a welding layer, and the wear-resistant layer 151 ensures that the baffle 15 is not worn by sacrificing itself in the working process.
Referring to fig. 4, in addition to this, a wear plate 152 may be added on the front side of the baffle 15, and the purpose of protecting the baffle 15 is achieved by wearing the wear plate 152. The wear-resisting plate 152 can be directly welded on the baffle 15, and can also be fixedly connected on the baffle 15 by bolts, but the place where the screw rod is connected with the nut needs to be welded to avoid falling off in the working process.
Considering that the baffle 15 mainly wears away near the bottom surface of the oblique trough 12, the wear-resisting plate 152 is staggered from the baffle 15, that is, one side of the wear-resisting plate 152 near the bottom surface of the oblique trough 12 is located below one side of the baffle 15 near the bottom surface of the oblique trough 12, and one side of the wear-resisting plate 152 far away from the bottom surface of the oblique trough 12 is located below one side of the baffle 15 far away from the bottom surface of the oblique trough 12, so that the wear-resisting plate can play an effective role in protection, and the wear of the baffle 15 is.
Referring back to fig. 1, in order to further improve the iron removing effect, the number of the gantry 13 is increased to a plurality, and correspondingly, the number of the baffle 15 and the electromagnet 16 is also increased. A plurality of portal frames 13 set up along the flow direction interval of the interior cement raw material of chute 12, carry out deironing many times to it, further reduce the content of iron impurity wherein.
Further, the length of the baffle 15 is controlled to be between one half and two thirds of the width of the chute 12, and one end of the baffle 15 is positioned as close to the side of the chute 12 as possible and staggered, so that the flow path of the cement raw material in the chute 12 is a curve similar to a wave, the residence time in the chute 12 is longer, and the contact time with the baffle 15 and the electromagnet 16 is also longer.
Furthermore, the end of the baffle 15 near the center of the chute 12 is inclined backwards, that is, the flowing direction of the cement raw material in the chute 12 is inclined, so that on one hand, the pressure applied to the baffle 15 can be further reduced, and on the other hand, the cement raw material can be pushed to flow towards the middle part of the chute 12, and the accumulation of the cement raw material at the edge of the chute 12 is avoided. Because the baffles 15 overlap at the middle of the chute 12, pushing the cement raw meal towards the middle increases the contact time with the electromagnets 16.
Relative to the flowing direction of cement raw materials in the inclined material groove 12, the inclination angle of the baffle 15 is 5-10 degrees, the angle range can play a good role in pushing, and the baffle 15 can be ensured to be overlapped in the middle of the inclined material groove 12.
Referring to fig. 5, the electromagnet and the cylinder are controlled by a programmable controller, i.e., a PLC, two connection ends of the cylinder are connected to a two-position three-way solenoid valve, two control ends of the two-position three-way solenoid valve are controlled by two relays, respectively, the control ends of the two relays are connected to the programmable controller, when the relays are connected, a corresponding circuit is connected, a valve core in the two-position three-way solenoid valve acts, and a piston rod in the corresponding cylinder extends or retracts.
The electromagnet 16 is connected with an external power supply, a relay is also arranged on the connecting line, the control end of the relay is connected with the programmable controller, and when the programmable controller sends a signal, the relay is switched on, the electromagnet 16 is electrified, and the work is started.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
