The position height of the water inlet pipe 28 is higher than that of the screen 16, and the position height of the water outlet pipe 29 is lower than that of the screen 16, on one hand, because the cooling water in the water inlet pipe 28 is lower, and the temperature of the cooling water in the water outlet pipe 29 is increased after passing through the barrel 1, in order to avoid the influence of the cooling water temperature in the water outlet pipe 29 on the cooling water temperature in the water inlet pipe 28, the position height of the water inlet pipe 28 is higher than that of the screen 16, and the position height of the water outlet pipe 29 is lower than that of the screen 16, the water inlet pipe 28 and the water outlet pipe 29 can be effectively separated, the influence of the cooling water temperature in the water outlet pipe 29 on the cooling water temperature of the water outlet pipe 29 is reduced, and the cooling efficiency of the cooling coil 27 on the temperature of the grinding field in the barrel 1 is improved. The structure that the distance between the water inlet pipe 28 and the water outlet pipe 29 is larger by the connecting line of the water inlet pipe 28 penetrating through the discharge end cover 31 and the connecting line of the water outlet pipe 29 penetrating through the discharge end cover 31 and the central point of the water outlet pipe 29 penetrating through the discharge end cover 31 further reduces the influence of the temperature of cooling water in the water outlet pipe 29 on the temperature of the cooling water in the water outlet pipe 29, and further improves the cooling efficiency of the cooling coil 27 on the temperature of a grinding field in the barrel 1.
The central axis of cooling coil 27 coincides with the central axis of barrel 1 for cooling coil 27 is more even to the cooling of grinding field area temperature in barrel 1, and the cooling effect is better.
The discharging end cover 31 is provided with a screen 16 mounting opening, the screen 16 enters the barrel 1 from the screen 16 mounting opening, and the screen 16 mounting opening can be sealed by the screen mounting cover plate 17. When the screen 16 needs to be detached from the inside of the barrel 1, the screen mounting cover plate 17 and the screen 16 can be moved out of the screen 16 mounting opening, and the cooling coil 27 is not affected by detaching the screen 16, so that the detaching and mounting are easier.
The length of the screen mounting cover plate 17 is larger than that of the mounting opening of the screen 16, the screen mounting cover plate 17 is in contact with the discharge end cover 31, and the structure improves the sealing effect of the screen mounting cover plate 17 on the mounting opening of the screen 16.
The screen mounting cover plate 17 is provided with a discharge pipe 32, the discharge pipe 32 is communicated with the inside of the screen 16, and the screen mounting cover plate 17 is detachably connected with the screen 16. The material in the screen cloth 16 can be discharged through the discharge pipe 32, and when the material in the screen cloth 16 can not be discharged from the discharge pipe 32, the material in the screen cloth 16 can be discharged after the screen cloth mounting cover plate 17 is detached, so that the cooling coil 27 cannot be influenced by the material discharged from the screen cloth 16, and the convenience in operation is improved.
The bottom of the cartridge assembly 33 is provided with a number of rollers 34. In the process of overhauling, a monkey is dismantled through bolts between the fixed barrel assemblies 33, the barrel assemblies 33 can slide out of the equipment through the rollers 34, and after the barrel assemblies 33 slide out of the equipment, the barrel assemblies 33 are finally transferred through the hoisting equipment, so that the labor cost is saved in the whole overhauling process, the operation is easy, and the overhauling efficiency is improved.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
