[0031] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 3 As shown, this utility model embodiment provides an inclined wet grinding mill unloading device, including a base 1, an inclined support 2, a wet grinding cylinder 3, an inclined support mechanism 4, a rotating mechanism 5, a support pulley assembly 6, and a limiting pulley assembly 7. The wet grinding cylinder 3 has a feed inlet 31 at one end and a discharge outlet 32 ​​at the other end. The wet grinding cylinder 3 is equipped with a plurality of steel balls for wet grinding. The steel balls are used to wet grind the material inside the wet grinding cylinder 3. The feed inlet 31 facilitates the feeding of cemented carbide raw materials and grinding liquid into the wet grinding cylinder 3, thereby forming an initial slurry environment. The steel balls can perform centrifugal motion along the inner wall under the rotation drive of the wet grinding cylinder 3, and collide and roll with each other, thereby continuously impacting and shearing the raw material particles inside, gradually breaking them down and refining them. At the same time, the dispersion effect of the liquid can promote the uniform mixing between particles of different sizes.

[0035] The wet grinding cylinder 3 is rotatably mounted on the inclined support 2 via the supporting pulley assembly 6. The rotating mechanism 5 is connected to the wet grinding cylinder 3 in a transmission manner. The rotating mechanism 5 is used to drive the wet grinding cylinder 3 to rotate. The rotating mechanism 5 can drive the wet grinding cylinder 3 to rotate around its own axis, so that the steel balls inside the wet grinding cylinder 3 roll and come into contact with the material, thereby impacting and shearing the material in multiple directions, thus completing the fine grinding and mixing of the cemented carbide raw material.

[0036] One end of the inclined support 2 is rotatably connected to the base 1 via a rotating shaft 21. The inclined support mechanism 4 is mounted on the base 1 and connected to the end of the wet grinding cylinder 3 away from the rotating shaft 21. The inclined support mechanism 4 is used to drive the inclined support 2 to rotate around the rotating shaft 21 to adjust the tilt angle of the discharge port 32. The inclined support mechanism 4 can drive the inclined support 2 to tilt upwards or downwards, thereby adjusting the tilt angle of the discharge port 32. Specifically, after wet grinding is completed, by controlling the action of the inclined support mechanism 4, the wet grinding cylinder 3 is tilted at a certain angle, so that the grinding slurry flows naturally to the discharge port 32 under the action of gravity, saving time and effort and effectively shortening the discharge time. At the same time, the tilt angle of the discharge can be flexibly adjusted according to the flow characteristics of different slurries to adapt to the process requirements of different raw materials.

[0037] The limiting pulley assembly 7 is located at the end of the inclined support 2 and abuts against the wet grinding cylinder 3. The limiting pulley assembly 7 is used to restrict the wet grinding cylinder 3 from sliding off the inclined support 2. This arrangement can provide limiting support without affecting the rotation of the wet grinding cylinder 3. When the wet grinding cylinder 3 is unloading, the limiting pulley assembly 7 can prevent it from sliding downward and prevent it from falling off the inclined support 2, thereby improving the unloading stability of the wet grinding mill.

[0038] like Figure 1 and Figure 3 As shown, the tilting support mechanism 4 further includes a first motor 41, a lead screw 42, a threaded seat 43, a mounting plate 44, and a diagonal brace 45. The lead screw 42 is rotatably mounted on the base 1. The bottom of the mounting plate 44 is connected to the lead screw 42 through the threaded seat 43. The threaded seat 43 is used to drive the mounting plate 44 to reciprocate in the horizontal direction when the lead screw 42 rotates. The first motor 41 is connected to the end of the lead screw 42 and is used to drive the lead screw 42 to rotate. One end of the diagonal brace 45 is hinged to the mounting plate 44, and the other end of the diagonal brace 45 is connected to the tilting bracket 2. The diagonal brace 45 is used to support and adjust the tilt angle of the tilting bracket 2. The first motor 41 can drive the lead screw 42 to rotate around its axis. The threaded seat 43 is threadedly engaged with the lead screw 42. During the rotation of the lead screw 42, it can drive the mounting plate 44 to reciprocate along its axial direction. When the mounting plate 44 moves with the threaded seat 43, it can drive the diagonal support arm 45 to swing, thereby adjusting the angle of the tilting bracket 2.

[0039] like Figure 1As shown, the rotating mechanism 5 further includes a second motor 51, a rotary gear 52, and a drive gear 53. The second motor 51 is mounted on the bottom of the inclined support 2 via a fixing bracket. The rotary gear 52 is sleeved on the wet grinding cylinder 3. The output shaft of the second motor 51 is connected to the drive gear 53, and the drive gear 53 and the rotary gear 52 are connected by a chain drive. When the chain drive drives the rotary gear 52 to rotate, the wet grinding cylinder 3 can rotate accordingly, thereby driving the steel balls to tumble continuously, thus realizing the wet grinding of cemented carbide materials.

[0040] like Figure 1 and Figure 2 As shown, the support pulley assembly 6 further includes a first support collar 61 and a first support wheel 62. The first support collar 61 is disposed at the tail of the wet grinding cylinder 3, and the first support wheel 62 is disposed on the inclined bracket 2 and slides against the first support collar 61, thereby supporting the wet grinding cylinder 3 and reducing the frictional resistance experienced by the wet grinding cylinder 3 during rotation. A first limiting baffle 611 is provided on the side end of the first support collar 61. The first limiting baffle 611 is used to limit and abut against the first support wheel 62 when the wet grinding cylinder 3 slides at an angle, so as to restrict the wet grinding cylinder 3 from slipping off the inclined bracket 2 during angle adjustment, thereby improving the installation stability of the wet grinding cylinder 3.

[0041] like Figure 2 As shown, the limiting pulley assembly 7 further includes a second support collar 71 and a second support wheel 72. The second support collar 71 is disposed at the head of the wet grinding cylinder 3, and the second support wheel 72 is disposed on the inclined bracket 2 and slides against the second support collar 71 to support the wet grinding cylinder 3 and reduce the frictional resistance experienced by the wet grinding cylinder 3 during rotation.

[0042] like Figure 2 As shown, the limiting pulley assembly 7 further includes a third support wheel 73. The second support collar 71 has a second limiting baffle 711 on its side. The third support wheel 73 is mounted on the inclined bracket 2 and slides against the second limiting baffle 711. The third support wheel 73 is used to limit and abut against the second limiting baffle 711 when the wet grinding cylinder 3 slides at an incline, thereby preventing the wet grinding cylinder 3 from slipping off the inclined bracket 2.

[0043] like Figure 2 As shown, the discharge port 32 is further provided with a filter screen 320. The filter screen 320 can prevent the steel balls from flowing out with the slurry, thereby realizing the automatic separation of materials and grinding media.

[0044] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
