Description

[0002] In the sintering operation of a sintering plant, in order to ensure the humidity of the material, a water spraying device that can be connected to a water source needs to be arranged in the mixer for sintering operation. As shown in Figure 1 In order to be able to spray water in the mixer, the water spraying device in the conventional mixer is usually a water spraying pipe 2 hung on a steel wire rope 1, and one end of the steel wire rope 1 is fixed on a hopper support 3 at the feeding end, and the other end is wound on a manual rope winding mechanism 4 at the discharging end after passing through the inside of the mixer cylinder 5.

[0003] Although the water spraying device in the conventional mixer can realize water spraying operation in the mixer cylinder 5 and ensure normal operation of production, because the steel wire rope 1 is fixed at both ends of the mixer cylinder 5, the water spraying pipe 2 hung below the steel wire rope 1 cannot be pulled out of the mixer cylinder 5 after installation, which causes the workers to have to enter the inside of the mixer cylinder 5 to repair, dredge the water spraying pipe and replace the nozzle and other parts during maintenance, and the inside wall of the mixer cylinder 5 is full of wet and corrosive materials, the space is relatively closed, the air is not good, and it is difficult to cut or weld in the mixer cylinder 5 and there is a safety hazard.

[0004] In addition, the water spraying pipe 2 in the conventional mixer cannot move, which also causes the water spraying area in the inside of the mixer cylinder 5 to be concentrated in one place, so that the humidity of the material in different areas during sintering operation is not uniform, which affects the quality of the product.

Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features.

[0061] Furthermore, the technical solutions of the various embodiments of the present application can be combined with each other, but it must be based on the fact that a person of ordinary skill in the art can realize it, and when the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0062] As shown in FIGS. Figure 2 and Figure 3 The present application provides a mixer with a reciprocating traction assembly, which comprises a mixing device provided with a barrel 20 for mixing materials; further, in order to uniformly wet the materials in the barrel 20 and facilitate maintenance, the mixer further comprises a water spraying pipe 71 for supplying water into the barrel 20 and a reciprocating traction assembly (not shown in the figure) for suspending and traction of the water spraying pipe 71; a person of ordinary skill in the art should know that the combination of the water spraying pipe 71 or the water spraying pipe 71 and the corresponding hanger can constitute a water spraying mechanism 7 for wetting the materials in the barrel 20.

[0063] In order to enable the pull rope 6 in the reciprocating traction assembly to move reciprocally and change direction, the traction side of the moving traction assembly is provided with a traction side base 19, a traction mechanism 8 for traction of the reciprocating movement of the pull rope 6, a first traction side pulley 9 and a second traction side pulley 10 for changing the direction of the pull rope 6; the driven side of the reciprocating traction assembly is provided with a driven side base 19 and a driven side pulley 11 for changing the direction of the pull rope 6.

[0064] Wherein, in order to enable the pull rope 6 to move and fix integrally in the transverse direction relative to the traction side base 19 and the driven side base 19, the first traction side pulley 9 and / or the second traction side pulley 10 are movably fixed to the traction side base 19 in the transverse direction, and the driven side pulley 11 is movably fixed to the driven side base 19 in the transverse direction.

[0065] Specifically, in order to make the pull rope 6 constitute a complete traction loop, the first end of the pull rope 6 is fixed to the traction mechanism 8, and the second end of the pull rope 6 passes through the first traction side pulley 9, the driven side pulley 11, and the second traction side pulley 10 in turn, and then returns and is fixed to the traction mechanism 8.

[0066] In order to spray water in the barrel 20 of the mixing machine, the water spraying pipe 71 is hung between the traction side and the driven side of the pull rope 6.

[0067] The working process of the above embodiment is as follows: the moving traction assembly for hanging and traction of the water spraying pipe 71 is combined and installed with the mixing device, thereby forming a mixing machine with the functions of back-and-forth movement and transverse movement water spraying and convenient maintenance.

[0068] It should be noted that in the field of sintering, the pull rope 6 is generally a steel wire rope; in addition, the traction side and the driven side are respectively located at the two side ends of the barrel 20. During initial installation, the first end of the pull rope 6 is fixed to the traction mechanism 8, the second end of the pull rope 6 passes through the inside of the barrel 20 after changing direction through the first traction side pulley 9, then passes through the inside of the barrel 20 again after changing direction through the driven side pulley 11, and is fixed to the traction mechanism 8 again after changing direction through the second traction side pulley 10.

[0069] During water spraying operation, under the traction of the traction mechanism 8, the pull rope 6 can move back and forth, so that the water spraying pipe 71 uniformly sprays water back and forth under the traction of the pull rope 6, thereby forming a water mist wall in the barrel 20; in addition, because the first traction side pulley 9 and / or the second traction side pulley 10 are movably fixed to the traction side base 19 in the transverse direction, and the driven side pulley 11 is movably fixed to the driven side base 19 in the transverse direction, the position of the water spraying pipe 71 in the barrel 20 can be adjusted in the transverse direction according to actual production needs.

[0070] When the maintenance work is carried out, the pulling rope 6 is pulled back and forth by the traction mechanism 8, so that the water jet pipe 71 is moved out of the inside of the barrel 20, and the maintenance personnel can disassemble and maintain the water jet pipe 71 outside, thereby reducing the maintenance cost and safety hidden danger; when the maintenance work is completed, the water jet pipe 71 is reassembled on the pulling rope 6, and the water jet pipe 71 is reset under the traction of the traction mechanism 8.

[0071] In order to pull the pulling rope 6 back and forth, the traction mechanism 8 comprises a rope winding assembly 81 and a power assembly (not shown in the figure) for driving the rope winding assembly 81; the rope winding assembly 81 comprises a winding drum 811 with a first winding part 8111 and a second winding part 8112; wherein the first winding part 8111 and the second winding part 8112 are oppositely arranged and respectively provided with spiral grooves with opposite rotation directions, so that the pulling rope 6 is wound in opposite directions in the first winding part 8111 and the second winding part 8112; it should be known that the power assembly can comprise a motor 82 with power-off braking function, an override box with operation remote control for controlling the forward and reverse rotation of the motor 82, and an open gear 83 for controlling the rotation speed and torque.

[0072] Reference Figure 4 The rope winding assembly 81 and the open gear 83 have a connection relationship, and the motor 82 is connected with the rope winding assembly 81 through the open gear 83.

[0073] The specific installation mode of the pulling rope 6 can be that the first end of the pulling rope 6 is fixed to the first winding part 8111, the second end of the pulling rope 6 passes through the first traction side pulley 9, the driven side pulley 11 and the second traction side pulley 10 in sequence, and is fixed to the second winding part 8112, so that the pulling rope 6 forms a traction loop around the traction side and the driven side; wherein the pulling rope 6 is wound with an original winding length on the first winding part 8111 and / or the second winding part 8112.

[0074] Specifically, as one installation mode of the pulley, the traction side of the back-and-forth moving traction assembly is further provided with a traction side pulley seat 91 installed on the traction side base 19, the traction side pulley seat 91 is movably fixed on the traction side base 19, and the first traction side pulley 9 and the second traction side pulley 10 are installed on the traction side pulley seat 91; wherein the traction side pulley can be one whole, or two traction side pulleys respectively with the traction side pulley seat 91 of the first traction side pulley 9 and the second traction side pulley 10.

[0075] The driven side of the reciprocating traction assembly is also provided with a driven side pulley seat (not shown in the figure) mounted on the driven side base 19, which is movably fixed on the driven side base 19 in the transverse direction, and the driven side pulley 11 is mounted on the driven side pulley seat.

[0076] In addition, in order to support the pull rope 6 and ensure the height of the pull rope 6, the traction side is also provided with a first traction side idler 12 corresponding to the first traction side pulley 9 and a second traction side idler 13 corresponding to the second traction side pulley 10; wherein the first traction side idler 12 and / or the second traction side idler 13 are movably fixed on the traction side base 19 in the transverse direction through a traction side idler seat 121.

[0077] The driven side is also provided with a first driven side idler 14 and a second driven side idler 15 corresponding to the two sides of the driven side pulley 11.

[0078] In order to ensure that the water jet pipe 71 can move transversely in the cylinder 20, the first driven side idler 14 and / or the second driven side idler 15 are movably fixed on the driven side base 19 in the transverse direction through a driven side idler seat (not shown in the figure).

[0079] In the case of setting the idler, the second end of the pull rope 6 passes through the first traction side pulley 9 after changing direction, and then passes through the first traction side idler 12, the first driven side idler 14, the driven side pulley 11, the second driven side idler 15 and the second traction side idler 13 in turn, and then changes direction again through the second traction side pulley 10 and returns to the traction mechanism 8.

[0080] As one of the above-mentioned motion states, as shown in Figure 6 When the winding drum 811 rotates, the first winding part 8111 winds into the pull rope 6, and the second winding part 8112 winds out of the pull rope 6 synchronously, so that the pull rope 6 moves towards the first winding part 8111, thereby driving the water jet pipe 71 in the water jet device to move.

[0081] As one of the above-mentioned movable fixations, the traction side sliding seat, the traction side idler seat 121, the driven side pulley seat, and the driven side idler seat are all provided with a long waist hole extending in the transverse direction to adjust the transverse position of the mounted part. For distinction, refer to Figure 7 and Figure 8 The long waist hole on the traction side pulley seat and the driven side pulley seat is a first long waist hole 911, and the long waist hole on the traction side idler seat 121 and the driven side idler seat is a second long waist hole 1211.

[0082] The traction side base 19 and the driven side base 19 are each provided with a mounting hole corresponding to the long waist hole.

[0083] As a preferred solution of the above embodiment, in order to reduce the resistance and friction of the pull rope 6, make the operation process more stable, and prolong the service life, the water spraying pipe 71 is hung on the pull rope 6 between the first traction side roller 12 and the first driven side roller 14.

[0084] Referring to Figure 2 and Figure 9 , the top rope groove center line of the first traction side roller 12, the rope groove center line of the first traction side pulley 9, and the bottom rope groove center line of the first winding part 8111 are at a first horizontal height.

[0085] The top rope groove center line of the second traction side roller 13, the rope groove center line of the second traction side pulley 10, and the top rope groove center line of the second winding part 8112 are at a second horizontal height; and the first horizontal height is lower than the second horizontal height.

[0086] The top steel wire rope groove center line of the first driven side roller 14, the top steel wire rope groove center line of the second driven side roller 15, and the steel wire rope groove center line of the driven side pulley 11 are at the same horizontal height.

[0087] As another preferred solution of the above embodiment, as shown in Figure 5 and Figure 10 , in order to realize mechanical limiting of the traction mechanism 8, the traction mechanism 8 further comprises a limiting assembly 16 for limiting rotation of the winding drum 811, and the limiting assembly 16 comprises a limiting plug and a fixing member for fixing the limiting plug.

[0088] The winding rope assembly 81 further comprises a winding drum shaft 812 penetrating through the winding drum 811 and connected with the power assembly, and a bearing seat supporting the winding drum shaft 812.

[0089] The winding drum shaft 812 is provided with at least one limiting groove 8121 for inserting the limiting plug at an end away from the power assembly, so as to mechanically limit the winding drum 811.

[0090] As a further improvement of the above-mentioned embodiment, the limiting grooves 8121 can be multiple, generally four, and the specific limiting method can be as follows: after the water spraying pipe 71 is pulled to the preset position, the opening of the limiting groove 8121 closest to the bottom of the reel shaft 812 is vertically downward, then the limiting block is inserted, the limiting block is fixed on the base 19 through the fixing member, the power of the motor 82 is turned off, and the motor 82 of the traction mechanism 8 is in an inoperative state during normal operation of the mixing machine, which is safer and saves power.

[0091] In addition, when the water spraying pipe 71 is disassembled and maintained, the pull rope 6 is provided with a positioning mark for positioning the reinstallation position of the water spraying pipe 71.

[0092] With reference to Figure 11 and Figure 12 , the positioning mark can include a positioning ring 17 fixed on the pull rope 6, wherein the water spraying pipe 71 adjacent to the driven side and the pull rope 6 are fixedly connected through the positioning ring 17.

[0093] Alternatively, the positioning mark can also include a positioning rope clamp 18 provided at the connection between the water spraying pipe 71 and the pull rope 6 and used for stabilizing the water spraying pipe 71, wherein the water spraying pipe 71 adjacent to the driven side is fixed on the pull rope 6 through the positioning rope clamp 18.

[0094] It should be noted that the water spraying pipe 71 is generally multiple, and the multiple water spraying pipes 71 are in communication with each other in the axial direction of the cylinder 20 and can be detachably arranged.

[0095] The application also provides a water spraying method of the mixing machine, comprising the steps of:

[0096] adjusting the transverse position of the first traction side pulley 9 and / or the second traction side pulley 10 on the traction side base 19 and the transverse position of the driven side pulley 11 on the driven side base 19;

[0097] controlling the traction direction of the traction mechanism 8, so that the water spraying pipe 71 sprays water forward and backward along the axial direction of the cylinder 20 to form a water mist wall.

[0098] As a further refinement and extension of the water spraying method, in order to achieve adjustment of the lateral position, during installation or maintenance, the long waist hole on the pulley seat and the supporting pulley seat and the mounting hole on the base 19 can be used for lateral adjustment, thereby causing the entire suspended water spraying pipe 71 to displace laterally, so that the water spraying angle of the entire water spraying pipe 71 is in the most suitable position; or a movable and fixed electric sliding groove and sliding rail can be provided, in the form of electric control, to real-time control the position of the pulley seat, the supporting pulley seat and the base 19.

[0099] During water spraying work, the water spraying position of the water spraying device of the conventional mixer is fixed, which results in a relatively large amount of water spraying in some areas and a relatively small amount of water spraying in some areas, which inevitably affects the mixing effect and causes an increase in the unqualified product rate. In the present application, in order to achieve control of the traction direction of the traction mechanism 8, the motor 82 of the traction mechanism 8 is set to be forward and reverse rotated at a certain frequency, so that the water spraying pipe 71 can be back and forth sprayed in the longitudinal direction of the mixer, forming a water mist wall, enhancing the water spraying effect, and at the same time making the water spraying more uniform, which is beneficial to the mixing of the mixture and improves the success rate of mixing and granulation.

[0100] Further, the motor 82 of the traction mechanism 8 can be forward and reverse rotated in the form of point control, and an override box and a remote controller with manual operation are arranged in the power assembly; during maintenance, the water spraying pipe 71 is pulled out of the cylinder 20 in sequence by controlling the remote controller, that is, by pressing the remote controller once, the motor 82 is started, the water spraying pipe 71 moves out of the cylinder 20, and after reaching the disassembly position, the remote controller is pressed again, the motor 82 is turned off, and the motor 82 stops running at the same time, and is automatically braked, at which time the maintenance personnel can perform disassembly and maintenance related operations on the water spraying pipe 71, and then sequentially complete the disassembly and maintenance of all the water spraying pipes 71.

[0101] After the maintenance work is completed, the water spraying pipe 71 is re-hung on the pull rope 6, and the reverse rotation of the motor 82 in the power assembly rotates the rope winding assembly 81, so that the steel wire rope moves in the reverse direction, thereby driving the water spraying pipe 71 to move into the mixer and return to the correct position. Since the water spraying pipe 71 closest to the driven side, i.e. the last water spraying pipe 71 pulled out, is arranged as a non-detachable structure and serves as a positioning reference point, when reloading, as long as all the water spraying pipes are sequentially entered into the cylinder 20, the water spraying pipe 71 returns to the initial ideal position, i.e. the entire reloading process is completed.

[0102] In addition, in order to ensure that the water spraying pipe 71 returns to the original position and the same number of winding turns are removed and inserted, the original winding length of the pull rope 6 in one winding part is adjusted to the maximum value and the original winding length of the pull rope 6 in the other winding part is adjusted to the minimum value, which can be 0, so that when the water spraying pipe 71 is removed, the winding part with the minimum value is wound into the pull rope 6 and the winding part with the maximum value is wound out of the pull rope 6, and when the water spraying pipe 71 is installed according to the positioning mark, when the pull rope 6 on the winding part with the minimum value is completely wound out or wound out to the set minimum value, it can be ensured that the water spraying pipe 71 has completely returned to the original position.

[0103] The above technical solutions of the present application are only preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like made under the technical concept of the present application, using the content of the present application specification and drawings, is included in the patent protection scope of the present application.
