Description

Technical Field

[0001] The utility model relates to the technical field of roller presses, in particular to a cement grinding roller press. Background Art

[0002] Cement is a common building material, and its raw materials need to be ground during processing. Roller presses are commonly used in cement production, primarily for crushing, grinding, and, to a certain extent, mixing the raw materials. After processing through a roller press, the cement raw materials become finer, helping to improve the quality and performance of the cement.

[0003] When the roller press is grinding cement, the outer wall will gradually wear out, causing the grinding roller to lose its grinding effect. The overall cost of replacing the grinding roller is high. For this reason, we propose a cement grinding roller press to solve the existing problem. Utility Model Content

[0004] The purpose of the utility model is to propose a cement grinding roller press in response to the problems existing in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cement grinding roller press, comprising a machine base, a hydraulic rod 1, a machine casing, a hydraulic rod 2 and a travel frame, the machine base and the machine casing being distributed in opposite directions, the machine casing being located inside the machine base, a hydraulic rod 1 being symmetrically distributed and connected to the outer wall of the machine casing being provided inside the machine base, a travel frame being relatively distributed being provided inside the housing, a motor being provided at one end of the travel frame, a grinding roller being rotatably mounted inside the travel frame being provided at the output end of the motor, a lining plate being distributed in a ring array on the outer wall of the grinding roller, and a hydraulic rod 2 being connected to the travel frame at a telescopic end being provided inside the housing.

[0006] Preferably, the inner walls on both sides of the upper end of the housing are provided with guide plates, and the inner walls of the guide plates are provided with guide grooves converging toward the center. The guide plates convey the cement raw materials and guide the cement raw materials to the centers of the two grinding rollers through the guide grooves.

[0007] Preferably, two sets of symmetrically distributed guide rails are provided inside the housing, and the lower end of the travel frame is slidably mounted on the outer wall of the guide rails. The travel frame is supported by the guide rails for sliding at the bottom inside the housing, and the stability of the travel frame is improved when it moves.

[0008] Preferably, the outer wall of the grinding roller is provided with a ring array of docking grooves, and the inner wall of the lining plate is provided with a docking block that is clamped into the inside of the docking groove. The lining plate is inserted into the docking groove through the docking block to achieve positioning docking with the grinding roller during installation.

[0009] Preferably, the inner wall of the lining plate is provided with a connecting block, and the connecting block and the front and rear ends of the grinding roller are rotatably connected with bolts. The connecting block and the grinding roller are installed by bolts, thereby fixing the lining plate to the outer wall of the grinding roller.

[0010] Preferably, the machine base is provided with inspection ports at both ends, and the lower end of the machine housing is provided with a discharge port. The inspection port provides a space for staff to inspect the grinding roller, and the ground cement raw materials are transported downward through the discharge port.

[0011] Preferably, the housing is butted against one end and a sealing gasket is provided on the butting surface so that the housing can be opened and closed by butting, and the sealing gasket improves the tightness of the closed end when closed.

[0012] Preferably, a guide rod is provided between the bases, and sleeves are provided at both the front and rear ends of the housing, each sleeve being slidably connected to the outer wall of the guide rod. A travel opening corresponding to the second hydraulic rod is provided inside the base. The travel opening ensures the movement of the second hydraulic rod when the housing moves, and the housing slides on the outer wall of the guide rod via the sleeve, thereby obtaining a lateral sliding guide.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The outer wall of the grinding roller of the utility model is covered with lining plates distributed in a ring array and of uniform specifications. After the lining plates are fixed to the outer wall of the grinding roller, the cement raw materials are squeezed and ground. The lining plates damaged by long-term use can be replaced separately, avoiding the replacement of the entire grinding roller and welding of the damaged parts, which has high labor and maintenance costs, thereby reducing the maintenance cost of the grinding roller.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 5 As shown, the cement grinding roller press proposed by the present invention includes a machine base 1, a hydraulic rod 1 4, a casing 6, a hydraulic rod 2 10 and a travel frame 11. The machine base 1 and the casing 6 are arranged in a split manner. The casing 6 is located inside the machine base 1. The machine base 1 is provided with symmetrically distributed hydraulic rods 1 4 connected to the outer wall of the casing 6. The casing 6 is provided with a relatively distributed travel frame 11. One end of the travel frame 11 is provided with a motor 13. The output end of the motor 13 is provided with a grinding roller 9 rotatably mounted inside the travel frame 11.

[0023] The inner walls of both sides of the upper end of the casing 6 are provided with guide plates 8, and the inner walls of the guide plates 8 are provided with guide grooves converging toward the center;

[0024] The outer wall of the grinding roller 9 is provided with docking grooves 19 distributed in a ring array, and the inner wall of the liner 15 is provided with docking blocks 18 that are clamped into the inside of the docking grooves 19;

[0025] The inner wall of the lining plate 15 is provided with a connecting block 16, and the connecting block 16 and the front and rear ends of the grinding roller 9 are rotatably connected with bolts 17;

[0026] The machine base 1 is provided with an inspection port 2 at both the front and rear ends, and a discharge port 14 is provided at the lower end of the machine housing 6;

[0027] A guide rod 3 is provided between the machine base 1, and a sliding sleeve 7 is provided at both the front and rear ends of the housing 6 and is slidably connected to the outer wall of the guide rod 3. A travel port 5 corresponding to the hydraulic rod 10 is opened inside the machine base 1;

[0028] Based on the implementation steps of Example 1: the cement raw materials are transported to the inside of the casing 6, and the cement raw materials are transported to the center of the grinding roller 9 through the guide plate 8. The motor 13 drives the grinding roller 9 to rotate. The grinding roller 9 is relatively lowered to roller-grind the cement raw materials passing through. The ground raw materials are output through the discharge port 14. When the liner 15 is worn out, the hydraulic rod 14 drives the casing 6 to open, the grinding roller 9 is exposed to the outside world, and the liner 15 in the position is disassembled. The new liner 15 is clamped in the docking groove 19 through the docking block 18, and the bolt 17 is rotated and inserted into the connecting block 16 and the inside of the grinding roller 9 to fix the replaced liner 15, thereby avoiding the overall replacement of the grinding roller 9 or the welding of the damaged part, which leads to maintenance difficulties and high maintenance costs, thereby reducing the maintenance cost of the grinding roller 9.

[0029] like Figure 1-Figure 5 As shown, the cement grinding roller press proposed by the present invention is compared with the embodiment 1, and this embodiment further includes: the outer wall of the grinding roller 9 is provided with a liner 15 distributed in a ring array, and the inside of the casing 6 is provided with a hydraulic rod 10 with a telescopic end connected to the travel frame 11;

[0030] Two sets of symmetrically distributed guide rails 12 are provided inside the housing 6, and the lower end of the travel frame 11 is slidably mounted on the outer wall of the guide rails 12;

[0031] The housing 6 is fitted at one end and the mating surface is provided with a sealing gasket;

[0032] In this embodiment, when the cement is roller-milled, the hydraulic rod 10 drives the travel frame 11 to move horizontally, and the bottom of the travel frame 11 is slidably supported by the guide rail 12 to maintain the stability of the travel frame 11, thereby adjusting the grinding roller 9. When the specifications of the cement raw materials change or the production process needs to change, the particle size of the cement roller mill is adjusted, thereby improving the flexibility of the roller press during use.
