Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure grinding mills, in particular to a high-pressure grinding mill. Background Art

[0002] The high-pressure grinding mill is improved on the basis of Raymond mill. The machine increases the centrifugal force of the grinding roller, that is, the grinding force on the material, through the high-pressure spring pressure. It is particularly suitable for materials with higher hardness below 9.3 on the Mohs hardness scale and ultra-fine powder processing with finer finished product particle size, the finest of which can reach 1000 mesh.

[0003] The China Patent Network discloses a high-pressure micro-powder mill for producing flaky sodium hydroxide, with publication number CN202715437U. While the entire high-pressure micro-powder mill's alkali grinding system forms a closed loop to prevent moist air from entering the system and causing partial deliquesce of the sodium hydroxide, the patent's feed port lacks a corresponding sealing structure, allowing external impurities to easily enter the mill through the feed port, affecting both the mill's operating efficiency and the quality of the powder.

[0004] For this purpose, a high pressure pulverizer is proposed. Utility Model Content

[0024] The utility model has a sealing door hingedly mounted on the outer wall of the high-pressure pulverizer body to seal the feed inlet. Under the action of a spring, a fixing rod is driven to move in a perforated hole. When one end of the fixing rod is engaged with the inside of the clamping hole, the sealing door can be fixed. Under the action of the sealing door, impurities from the outside can be prevented from entering the interior of the high-pressure pulverizer body through the feed inlet. On the one hand, the working efficiency of the high-pressure pulverizer body is improved, and on the other hand, the quality of the powder is also improved.

[0025] And by pulling the fixing rod through the auxiliary plate, the spring will perform a stretching movement. After one end of the fixing rod is disengaged from the clamping hole, the sealing door can be moved and the feed port can be exposed. In summary, compared with the existing ones, the utility model is convenient for closing and opening the sealing door and is relatively simple to use.

[0026] When inspecting and maintaining the main body of the high-pressure grinding mill, the hydraulic jack can be started to lift the main body of the high-pressure grinding mill so that the inspection port is at a certain height from the ground, thereby facilitating the inspection and maintenance of the main body of the high-pressure grinding mill;

[0027] It should be noted that before starting the hydraulic jack, the shaft needs to be rotated in advance. The shaft drives the threaded rod to move in the threaded hole. Wait until one end of the threaded rod is out of the limit hole.

[0028] And through the movable limit bar, the limit bar is located inside the second U-shaped block, and then by rotating the rotating shaft, the rotating shaft drives the threaded rod to move in the threaded hole. After one end of the threaded rod is clamped into the limiting hole, the limit bar can be fixed. At this time, the high-pressure grinding mill body can be auxiliary supported by the limit bar, thereby improving the stability of the high-pressure grinding mill body during operation.

In summary, compared with the existing ones, the present invention is convenient for closing and opening the sealing door 6 and is relatively simple to use.

[0048] Secondly, when the high-pressure grinding mill body 2 is to be repaired, the hydraulic jack 15 is activated. Under the action of the hydraulic jack 15, the high-pressure grinding mill body 2 can be lifted so that the inspection port 1 is at a certain height from the ground, thereby facilitating the repair and maintenance of the high-pressure grinding mill body 2;

[0049] It should be noted that before starting the hydraulic jack 15, the rotating shaft 23 needs to be rotated in advance. The rotating shaft 23 drives the threaded rod 24 to move in the threaded hole 22 until one end of the threaded rod 24 is disengaged from the limiting hole 21.

[0050] And through the movable limit bar 19, the limit bar 19 is located inside the second U-shaped block 20, and then by rotating the rotating shaft 23, the rotating shaft 23 drives the threaded rod 24 to move in the threaded hole 22. After one end of the threaded rod 24 is clamped into the limiting hole 21, the limit bar 19 can be fixed. At this time, under the action of the limit bar 19, the high-pressure grinding mill body 2 can be auxiliary supported, thereby improving the stability of the high-pressure grinding mill body 2 during operation.
