Description

Technical Field

[0001] The utility model belongs to the technical field of ball mills, and in particular relates to a desulfurization ball mill and a lining replacement manipulator thereof. Background Art

[0002] Desulfurization ball mill is an important industrial equipment, mainly used in flue gas desulfurization system to process limestone and other materials. Its main components include feeding part, discharging part, rotating part and transmission part. These parts work together to ensure the normal operation of the ball mill.

[0003] The feeding part is responsible for feeding raw materials such as limestone into the ball mill, while the discharging part is responsible for discharging the ground materials. The rotary part is the core part of the ball mill, where the cylinder rotates under the drive of the motor, driving the steel balls inside to impact and grind the materials. The transmission part is responsible for providing power to the rotary part to ensure the stable rotation of the cylinder.

[0004] The design of the desulfurization ball mill takes into account wear resistance and stable operation. The cylinder is inlaid with wear-resistant lining to extend the service life of the equipment. At the same time, the ball mill adopts rolling friction transmission between metal wheels and wear-resistant polymer material wheels, which reduces noise and wear and improves the reliability and stability of the equipment.

[0005] The liner needs to be replaced after reaching a certain degree of wear; in the early days, it was replaced manually, but it was time-consuming and laborious. Now it is basically replaced by a robot, but due to the fixing method of the liner, the external nut needs to be removed before the liner can be removed; this requires the internal robot to cooperate with the external nut removal, which leads to low overall efficiency. When installing, it is also necessary to install the liner on the inner wall first and then tighten the external nut to fix it. Therefore, whether it is removal or installation, the cooperation of internal and external staff is required. Utility Model Content

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Example 1

[0041] like Figure 1-9 As shown, a desulfurization ball mill includes a cylinder 101 and a lining layer. The lining layer is fixedly arranged on the inner wall of the cylinder 101. The lining layer is composed of a plurality of rows of lining plates. Each row of lining plates is composed of a first lining plate 102, a tail lining plate 104 and a plurality of intermediate lining plates 103.

[0042] The first lining plate 102, the middle lining plate 103 and the tail lining plate 104 are plugged in sequence; for this purpose, a corresponding plug-in structure is provided between the first lining plate 102, the middle lining plate 103 and the tail lining plate 104, and the specific structure is as follows:

[0043] A card slot 105 is provided at the rear end of the first lining plate 102 and each intermediate lining plate 103, and a plug-in portion 106 corresponding to the card slot 105 is provided at the front end of the tail lining plate 104 and each intermediate lining plate 103. That is, the first lining plate 102 is not provided with a plug-in portion 106, and the tail lining plate 104 is not provided with a card slot 105; the plug-in portion 106 and the card slot 105 are provided at both ends of the intermediate lining plate 103, respectively.

[0044] When the plug-in portion 106 is inserted into the slot 105, the plug-in portion 106 is restricted from radial movement, that is, the front ends of the middle liner 103 and the tail liner 104 can be effectively fixed. Specifically, the two sides of the slot 105 are beveled edges, forming a structure similar to a dovetail slot.

[0045] During installation, first fix the first lining plate 102 in the cylinder 101, then insert the plug-in portion 106 of one of the intermediate lining plates 103 into the slot 105 of the first lining plate 102, and then fix the intermediate lining plate 103; then plug and fix the intermediate lining plates 103 one by one (plug one and fix one) until the last intermediate lining plate 103 is plugged and fixed; finally, insert the plug-in portion 106 of the tail lining plate 104 into the slot 105 of the last intermediate lining plate 103, and fix the tail lining plate 104.

[0046] The first liner 102, the middle liner 103 and the tail liner 104 are fixed to the cylinder 101 in the following manner. Specifically, a first bolt 107 fixed to the cylinder 101 is provided at the front end of the first liner 102 and the rear end of the tail liner 104. The first bolt 107 passes through the cylinder 101 and is connected to the first nut 108, and is fixed by tightening the first nut 108. A second bolt 109 fixed to the cylinder 101 is provided at the slot 105 of the first liner 102 and each middle liner 103. The second bolt 109 passes through the cylinder 101 and is connected to the second nut 110, and is fixed by tightening the second bolt 109. A connecting cylinder 111 plugged with the second nut 110 is provided on the cylinder 101, and a groove corresponding to the shape of the second nut 110 is provided in the connecting cylinder 111, that is, the rotation of the second nut 110 can be restricted after insertion.

[0047] That is, the first lining plate 102 is fixed by the first bolts 107 and the second bolts 109 , the middle lining plate 103 is fixed by the second bolts 109 , and the tail lining plate 104 is fixed by the first bolts 107 .

[0048] The specific fixing method is as follows: first, place the first lining plate 102 at the desired fixing position, insert the first bolt 107 and the second bolt 109 respectively, the first bolt 107 passes through the cylinder 101 and is connected to the first nut 108, and is fixed by tightening the first nut 108; the second bolt 109 passes through the cylinder 101 and is connected to the corresponding second nut 110, and since the second nut 110 is fixed, the second bolt 109 can be tightened internally. For the intermediate lining plate 103, insert the plug-in portion 106 of the first intermediate lining plate 103 into the slot 105 of the first lining plate 102, and then fix it by tightening the second bolt 109 internally; then insert the intermediate lining plates 103 one by one and also fix them by tightening the second bolt 109 internally. For the tail lining plate 104, insert the plug-in portion 106 of the tail lining plate 104 into the slot 105 of the last intermediate lining plate 103, and then fix it by inserting the first bolt 107 and tightening the first nut 108 externally.

[0049] The above method can realize the sequential plug-in fixation between the first lining plate 102, the middle lining plate 103 and the tail lining plate 104. And because the plug-in portion 106 can block the head of the second bolt 109 after being inserted into the slot 105, the head of the second bolt 109 can be prevented from being exposed to the outside, thereby preventing damage that affects the next disassembly and assembly.

[0050] Furthermore, radial connection holes 112 are provided at the rear end of the tail liner 104 and the slot 105, and the plug-in portion 106 is provided with radial posts 113 plugged into the radial connection holes 112. Through the above structure, after the first liner 102, the middle liner 103 and the tail liner 104 are plugged in sequence, the radial movement of the middle liner 103 can be further restricted (to prevent the plug-in end from tilting). More importantly, the radial connection holes 112 can be used to cooperate with the manipulator 201 for disassembly and assembly operations. That is, the above radial connection holes 112 have the above two functions.

[0051] Furthermore, the upper surfaces of the first lining plate 102 , the middle lining plate 103 and the tail lining plate 104 are all wavy.

[0052] Furthermore, in order to prevent the second nut 110 from falling off, a positioning marble 114 is provided on the connecting tube 111, and a corresponding positioning groove is provided on the second nut 110. When the second nut 110 is inserted into the connecting tube 111, the positioning marble 114 can be inserted into the corresponding positioning groove. Furthermore, the above-mentioned radial and axial directions are determined based on the cylinder 101.

[0053] Example 2

[0054] This embodiment provides a lining replacement robot matched with the above lining plate on the basis of embodiment 1, such as Figure 10-15As shown, it includes a manipulator 201. A clamping and mounting mechanism 202 is provided on the manipulator 201; the clamping and mounting mechanism 202 is mainly used to cooperate with the first lining plate 102, the middle lining plate 103 and the tail lining plate 104 mentioned above.

[0055] The clamping and mounting mechanism 202 includes a fixed plate 203 and a mounting frame 204. The fixed plate 203 is hinged to the manipulator 201, and a first adjusting cylinder 205 is provided at the hinge. The angle between the fixed plate 203 and the manipulator 201 can be adjusted by the extension and contraction of the first adjusting cylinder 205. The mounting frame 204 is slidably connected to the fixed plate 203, and a first push cylinder 206 is provided between the mounting frame 204 and the fixed plate 203. The first push cylinder 206 is extended and contracted to drive the mounting frame 204 to move axially.

[0056] A bolt installation wrench 207 is slidably connected to the mounting frame 204, and a second push cylinder 208 is provided between the bolt installation wrench 207 and the mounting frame 204, and the bolt installation wrench 207 is driven to move radially by the second push cylinder 208. For the bolt installation wrench 207, a pneumatic or hydraulic wrench in the prior art can be used. The bolt installation wrench 207 is used to install the second bolt 109, and a magnet is provided on the bolt sleeve of the bolt installation wrench 207, and the second bolt 109 can be attracted by magnetic attraction. Of course, the second bolt 109 can also be fixed by providing a positioning marble 114 on the bolt sleeve.

[0057] A fork 209 is fixedly connected to the mounting frame 204, and the fork 209 can be inserted into the radial connection hole 112, so as to move the lining plate. A pressing plate 210 is slidably connected to the mounting frame 204, and a third push cylinder 211 is provided between the mounting frame 204 and the pressing plate 210. The pressing plate 210 is driven to move radially by the third push cylinder 211, so that the pressing plate 210 presses the lining plate.

[0058] The specific replacement method is as follows: first remove the first nuts 108 on the front liner 102 and the rear liner 104 from the outside, and then pull out the corresponding first bolts 107 from the inside of the cylinder 101. Then, the manipulator 201 can be used to reach into the cylinder 101 for disassembly.

[0059] The disassembly process of the tail liner 104 is as follows: the manipulator 201 moves the clamping installation mechanism 202 to the tail liner 104, aligning the fork 209 with the radial connection hole 112 on the tail liner 104; then the fork 209 is inserted into the radial connection hole 112 by extending the first push cylinder 206; the third push cylinder 211 is extended to make the pressure plate 210 press the tail liner 104. Finally, the first push cylinder 206 is retracted, and drives the tail liner 104 to move, so that it is separated from the middle liner 103. The manipulator 201 moves the removed tail liner 104 out of the cylinder 101. After it is moved to the specified position (such as in the material frame 220 described below), the third push cylinder 211 retracts so that the pressure plate 210 no longer presses the tail liner 104. After the manipulator 201 drives the clamping and mounting mechanism 202 as a whole, the fork head 209 is moved out of the radial connecting hole 112, thereby achieving separation / placement from the tail liner 104.

[0060] The disassembly method of the first liner 102 and the middle liner 103 is the same; the manipulator 201 moves the clamping installation mechanism 202 to the middle liner 103, aligning the fork head 209 with the radial connection hole 112 on the middle liner 103; the fork head 209 is inserted into the radial connection hole 112 by extending the first push cylinder 206; the third push cylinder 211 is extended to make the pressing plate 210 press the middle liner 103. Then, the second push cylinder 208 is extended to drive the bolt installation wrench 207 to move radially downward, so that the bolt sleeve is inserted into the second bolt 109; the bolt installation wrench 207 is started to rotate to loosen the second bolt 109 (the second push cylinder 208 is retracted in the process of loosening), and the second bolt 109 is taken out manually after loosening; or the second bolt 109 is taken out by magnetic attraction of the bolt sleeve. Finally, the first push cylinder 206 is retracted, and drives the middle liner 103 to move, so that it is separated from other middle liners 103. The manipulator 201 moves the removed intermediate liner 103 out of the cylinder 101, and after it is moved out to the specified position (such as in the material frame 220 described below), the third push cylinder 211 retracts so that the pressing plate 210 no longer presses the intermediate liner 103. After the manipulator 201 drives the clamping installation mechanism 202 as a whole, the fork head 209 is moved out of the radial connection hole 112, and the separation / placement of the intermediate liner 103 can be achieved. The disassembly method of the first liner 102 is similar, so it will not be described in detail here. Through the above operation, one row of liner plates can be completely disassembled, and the removal method of the remaining rows of liner plates is similar.

[0061] Each row of lining is installed as follows:

[0062] First install the first lining plate 102. The manipulator 201 moves the clamping installation mechanism 202 to the new first lining plate 102, aligning the fork 209 with the radial connection hole 112 on the first lining plate 102; the fork 209 is inserted into the radial connection hole 112 by extending the first push cylinder 206; the third push cylinder 211 is extended to make the pressing plate 210 press the first lining plate 102. The manipulator 201 drives the new first lining plate 102 to the installation position of the first lining plate 102; the first bolt 107 is manually inserted into the first lining plate 102, and the first nut 108 is tightened externally to fix it. After that, the third push cylinder 211 is retracted so that the pressing plate 210 no longer presses the first lining plate 102, and the fork 209 is moved out of the radial connection hole 112 by retracting the first push cylinder 206.

[0063] After that, the intermediate liner 103 is installed. The manipulator 201 moves the clamping installation mechanism 202 to the new intermediate liner 103, aligning the fork 209 with the radial connection hole 112 on the intermediate liner 103; the first push cylinder 206 extends to insert the fork 209 into the radial connection hole 112; the third push cylinder 211 extends to make the pressing plate 210 press the intermediate liner 103. The manipulator 201 drives the new intermediate liner 103 to move to the rear of the first liner 102, aligning the plug-in portion 106 of the new intermediate liner 103 with the card slot 105 on the first liner 102; then the first push cylinder 206 continues to extend to drive the plug-in portion 106 of the new intermediate liner 103 to be inserted into the card slot 105 on the first liner 102. Finally, the second bolt 109 is manually inserted into the new intermediate liner 103, and the second push cylinder 208 is extended to drive the bolt installation wrench 207 to move radially downward, so that the bolt sleeve is inserted into the second bolt 109, and the bolt installation wrench 207 is started to rotate to tighten the second bolt 109. After tightening, the second push cylinder 208 is retracted to drive the bolt installation wrench 207 to move radially upward, so that the bolt sleeve is removed from the second bolt 109. The third push cylinder 211 is retracted so that the pressure plate 210 no longer presses the intermediate liner 103, and the fork head 209 is removed from the radial connection hole 112 by retracting the first push cylinder 206; then the remaining intermediate liners 103 are installed, and the manipulator 201 moves the clamping installation mechanism 202 to the next new intermediate liner 103, and so on to install each intermediate liner 103 in sequence.

[0064] Finally, the tail liner 104 is installed. The manipulator 201 moves the clamping installation mechanism 202 to the new tail liner 104, aligning the fork 209 with the radial connection hole 112 on the tail liner 104; the fork 209 is inserted into the radial connection hole 112 by extending the first push cylinder 206; the third push cylinder 211 is extended to press the pressure plate 210 against the tail liner 104. The manipulator 201 drives the new tail liner 104 to move to the rear of the last intermediate liner 103, aligning the plug-in portion 106 of the new tail liner 104 with the card slot 105 on the last intermediate liner 103; then the first push cylinder 206 continues to extend to drive the plug-in portion 106 of the new tail liner 104 to insert into the card slot 105 on the last intermediate liner 103. The first bolt 107 is manually inserted into the tail liner 104, and the first nut 108 is tightened externally to fix it. Afterwards, the third push cylinder 211 retracts so that the pressure plate 210 no longer presses the tail lining plate 104 , and the fork head 209 is moved out of the radial connecting hole 112 by retracting the first push cylinder 206 .

[0065] At this point, the installation of one row of lining plates is completed, and the installation of the remaining rows of lining plates is similar.

[0066] Furthermore, the first adjusting cylinder 205 , the first pushing cylinder 206 , the second pushing cylinder 208 , and the third pushing cylinder 211 may all be oil cylinders.

[0067] Furthermore, in order to avoid crushing the lining plate, a rubber strip 212 is fixedly connected to the lower surface of the pressing plate 210.

Taking the gear rack mechanism as an example, a rack is fixed under the crossbeam 214; a gear meshing with the rack is rotatably connected to the body 213, and the gear is connected to a driving motor. The rack is driven to rotate by the driving motor, thereby driving the crossbeam 214 to move and extend into the cylinder 101. Specifically: a rotatable walking wheel is provided on the body 213.

[0069] A turntable 216 is fixedly connected to the front end of the crossbeam 214, and a driving arm is provided on the turntable 216, and the driving arm is driven to rotate by the turntable 216. The driving arm includes a large arm 217 and a small arm 218, the large arm 217 is fixedly connected to the turntable 216, the rear end of the small arm 218 is hinged to the upper end of the large arm 217, and an angle adjustment cylinder 219 is hinged between the large arm 217 and the small arm 218; the fixed plate 203 is hinged to the front end of the small arm 218.

[0070] Furthermore, a movable material frame 220 is provided on the crossbeam 214; the material frame 220 can also be moved by a gear rack structure; specifically, a rack is provided above the crossbeam 214, and a gear (connected to a motor) meshing with the rack is provided on the material frame 220. The removed liner (first liner 102, middle liner 103, and tail liner 104) can be placed in the material frame 220, and the material frame 220 moves to remove it from the cylinder 101. In addition, a new liner can also be placed in the material frame 220, and the material frame 220 moves to send it into the cylinder 101.

[0071] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention, and various changes should be included in the protection scope of the present invention.
