Description

Technical Field

[0001] The utility model relates to the technical field of cement grinding, in particular to a high-extrusion-force cement grinding device. Background Art

[0002] Cement grinding is the final process in cement manufacturing. Its main function is to grind cement clinker (and retarder, performance adjustment material, etc.) to a suitable particle size (expressed in terms of fineness, specific surface area, etc.), form a certain particle gradation, increase its hydration area, accelerate the hydration rate, and meet the coagulation and hardening requirements of cement paste.

[0003] In order to grind cement raw materials of different sizes, the existing technology generally uses rollers for extrusion grinding. However, after long-term use of the grinding mill, cement materials will stick to the extrusion rollers, which need to be manually cleaned. However, the grinding rollers are generally located inside, making cleaning inconvenient, and thus need to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a high-extrusion force cement grinding device to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a high extrusion force cement grinding device, comprising a mounting base, a grinding machine body and a frame,

[0014] Preferably, brackets are welded at both ends of the outer surface of the grinding mill body, and the bottom end surface of the bracket is welded to the mounting base. The grinding mill body is mounted and fixed on the mounting base through the bracket.

[0015] Preferably, a support block is welded to the bottom end surface of the mounting base, and there are four support blocks in total, and the four support blocks are distributed in a rectangular array relative to the mounting base. The mounting base can be mounted and supported by the support blocks.

[0016] Preferably, a feed pipe is embedded and fixed on the top surface of the grinding mill body, and the feed pipe is connected to the grinding mill body. The cement material to be ground can be injected into the grinding mill body through the feed pipe.

[0017] Preferably, a discharge pipe is embedded and fixed on the bottom end surface of the grinding mill body, the discharge pipe is connected to the grinding mill body, and a valve is installed on the discharge pipe through a flange. The cement material ground in the grinding mill body can be discharged by opening the valve on the discharge pipe.

[0021] 1. The utility model sets a grinding mill body. When grinding cement, the personnel can inject the cement material to be ground into the grinding mill body through the feed pipe. When the cement material is injected, it reaches the grinding roller shaft after passing through the limit of the guide plate. When it reaches, the personnel can open the hydraulic rod to push the frame to move according to the actual required extrusion force. When the frame moves, the distance between the two grinding roller shafts can be adjusted. The extrusion force during cement grinding can be adjusted by adjusting the distance between the grinding roller shafts. After adjustment, the driving mechanism can be opened to drive the grinding roller shaft to rotate, so that the cement passes through the grinding roller. The high extrusion pressure of the axis is used for grinding, and after grinding, the personnel can observe the quality of cement after grinding and continue to manually adjust the spacing to adjust the extrusion pressure. After the cement is discharged, the personnel can open the hydraulic rod to drive the grinding roller to reach the nozzle and continue to rotate. During rotation, the water pump can be driven to extract clean water from the water storage tank and inject it into the discharge pipe, so that the clean water in the discharge pipe can be sprayed on the grinding roller through the nozzle for cleaning, and the clean water can be discharged through the discharge pipe, thereby avoiding the grinding roller from sticking to the cement material and affecting the later processing, and avoiding the inconvenience caused by manual cleaning and maintenance.

[0022] 2. The utility model sets a water storage tank. When personnel clean and maintain the cement grinding roller after grinding, they can turn on the fan to intake air into the grinder body through the air intake pipe. During the intake, the gas can be heated by installing an electric heating wire in the air intake pipe. The gas is heated to a preset temperature of the electric heating wire and then discharged into the grinder body. The heated gas heats and dries the grinder body and is discharged through the air outlet pipe after drying. The interior is sprayed and cleaned and then dried, thereby meeting the needs of later cleaning and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] An air outlet pipe 6 and an air inlet pipe 9 are embedded and fixed on the top surface of the grinding mill body 5, and a fan 8 is installed in the air inlet pipe 9. A heating wire can be installed in the air inlet pipe 9, so that the air inlet pipe 9 can heat the gas through the heating wire when the air is taken into the grinding mill body 5, so that the gas passes through the heating wire and reaches the preset drying temperature before entering the grinding mill body 5;

[0034] A guide plate 16 is welded to the inner wall of the grinding mill body 5;

[0035] A liquid discharge pipe 19 is installed on the rear end surface of the inner wall of the grinding mill body 5, and a nozzle 13 is installed on the liquid discharge pipe 19;

[0036] Hydraulic rods 18 are installed at both ends of the grinding mill body 5, and a frame 15 is arranged on the output shaft of the hydraulic rod 18;

[0037] The front end surface of the frame 15 is equipped with a driving mechanism 12, and the output shaft of the driving mechanism 12 is provided with a grinding roller shaft 17;

[0038] A water pump 22 is installed in the water storage tank 4 , and the water pump 22 is in liquid communication with the liquid discharge pipe 19 via the liquid outlet pipe 21 .

[0039] As is well known to those skilled in the art, the provision of the control panel 10, the driving mechanism 12, the fan 8, the heating wire and the water pump 22 is commonplace, and the control panel 10 can be connected to an external power source and connected to the driving mechanism 12, the fan 8, the heating wire and the water pump 22 through a wire, so that the control panel 10 can control the driving of the driving mechanism 12, the fan 8 and the water pump 22 and the temperature of the heating wire, which are all conventional means or common knowledge, and will not be repeated here, and those skilled in the art can make any selection according to their needs or convenience. The driving mechanism 12 drives the grinding roller shaft 17 to rotate.

[0040] A feed pipe 7 is embedded and fixed in the top surface of the grinding mill body 5 , and the feed pipe 7 is communicated with the grinding mill body 5 . The cement material to be ground can be injected into the grinding mill body 5 through the feed pipe 7 .

The extrusion force during cement grinding can be adjusted by adjusting the distance between the grinding roller shafts 17. After adjustment, the driving mechanism 12 can be opened to drive the grinding roller shaft 17 to rotate, so that the cement passes through the grinding machine. The high extrusion pressure of the roller 17 is used for grinding, and after grinding, the personnel can observe the quality of the cement after grinding and continue to manually adjust the spacing to adjust the extrusion pressure. After the cement is discharged from the grinding, the personnel can open the hydraulic rod 18 to drive the grinding roller 17 to reach the nozzle 13 and continue to rotate. During rotation, the water pump 22 can be driven to extract the clean water in the water tank 4 and inject it into the drain pipe 19, so that the clean water in the drain pipe 19 can spray and clean the grinding roller 17 through the nozzle 13, and the clean water can be discharged through the discharge pipe 3, thereby preventing the grinding roller 17 from sticking to the cement material and affecting the later processing.
