[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1-5 As shown, a pre-crushing and mixing device for oil suspension production includes a lower hopper 1 and a crushing roller 2, including:

[0026] A rotary filter screen 3 is obliquely disposed in the lower hopper 1 and driven to rotate, and a plurality of first comb teeth 33 for lifting solids are arranged in a linear array on the rotary filter screen 3, and adjacent first comb teeth 33 are staggered with each other;

[0027] The drop plate 4 disposed inside the lower hopper 1 is used to carry solid objects, and a drop channel pointing to the crushing roller 2 is disposed on the drop plate 4 .

[0028] Specifically, the bottom of the lower hopper 1 is an inclined surface, and the inner walls of the upper and lower ends of the rotary filter 3 are provided with turning rollers, and the drop plate 4 is located directly below the turning roller at the upper end of the rotary filter 3. A guide block 42 is provided in the middle of the upper side of the drop plate 4 to guide the fallen solids to both sides and enter the falling channel; the raw materials are put into the lower hopper 1, and the raw materials are crushed by the crushing roller 2. The powder particles contact the rotary filter 3 along the bottom of the lower hopper 1 and are sieved by the rotary filter 3. The powder particles with small particle size pass through the rotary filter 3 and enter the next process, while the solids with larger particle size are screened by the first comb teeth. 33 intercepts and lifts upward along the surface of the rotary filter 3, wherein part of the raw material powder particles will be deposited between the lower end of the rotary filter 3 and the bottom of the lower hopper 1, and this part of the raw material powder particles will also be lifted by the first comb teeth 33. When reaching the uppermost end, the first comb teeth 33 are driven by the steering roller to change the transmission direction, so that the intercepted solid matter naturally falls under the action of gravity and falls into the drop plate 4, and passes through the falling channel pointing to the crushing roller 2, so that the solid matter falls on the crushing roller 2 again and is crushed for the second time, and this process is repeated many times until all the raw material powder particles pass through the rotary filter 3.

[0029] In the above technology, solids with larger particle sizes are intercepted by the first comb teeth 33 through the inclined rotary filter 3 and lifted upward along the surface of the rotary filter 3. When reaching the uppermost end, the first comb teeth 33 are driven by the steering roller to change the transmission direction, so that the intercepted solids fall into the drop plate 4 and pass through the drop channel, so that the solids fall onto the crushing roller 2 again and are crushed for the second time. After the device is turned on, the solids can be lifted continuously and crushed for the second time through the drop channel, thereby reducing the number of operating steps.

[0030] As an embodiment further provided by the present invention, a heavy screen roller 34 is rotatably provided in the lower hopper 1, and the heavy screen roller 34 is located at the upper end of the rotary filter screen 3 to crush solid matter.

[0031] Specifically, the heavy screen roller 34 can be driven by the output shaft of the driving motor or rotated by hand, and the large-size solid matter is lifted by the first comb teeth 33 until it contacts the heavy screen roller 34 at the upper end of the rotating filter screen 3 and is crushed by the heavy screen roller 34, so that the large-size solid matter is preliminarily crushed to facilitate subsequent crushing. Then, the transmission direction of the first comb teeth 33 is changed, so that the solid matter falls into the drop plate 4.

[0032] As another embodiment further provided by the present invention, a plurality of second comb teeth 35 are arranged in a circular array on the heavy screening roller 34 .

[0033] Specifically, during the rotation of the heavy screening roller 34 , the second comb teeth 35 are staggered with the first comb teeth 33 to screen out and crush the solid matter between the gaps between two adjacent teeth of the first comb teeth 33 to prevent the solid matter from getting wet and adhering to the first comb teeth 33 .

[0034] As another embodiment further provided by the present invention, a driven gear 31 meshing with the driving gear 32 is provided on the heavy screen roller 34 .

[0035] Specifically, a driving gear 32 is provided on the steering roller at the upper end of the rotary filter 3. The rotary filter 3 is driven by a motor, so that the steering roller at the upper end rotates, thereby driving the driving gear 32 to rotate. The driving gear 32 drives the driven gear 31 to rotate through meshing transmission, so that the heavy screen roller 34 rotates, and the rotation direction of the heavy screen roller 34 is opposite to that of the driving gear 32. When the heavy screen roller 34 rotates, it drives the second comb teeth 35 to move the solids on the rotary filter 3 along the tangential direction to prevent the solids from sticking to the rotary filter 3.

[0036] As another embodiment further provided by the present invention, a rotating member 38 is provided on the inner wall of the lower hopper 1 , and there is a triggering station in the rotation stroke of the rotating member 38 for striking the drop plate 4 .

[0037] Specifically, a transmission belt 36 is connected between the rotating member 38 and the driving gear 32, and an elastic block 41 is provided on the drop plate 4. When the driving gear 32 rotates, the rotating member 38 is driven to rotate through the transmission belt 36, so that the rotating member 38 and the driving gear 32 maintain synchronous movement. After the rotating member 38 rotates to a certain angle, it collides with the elastic block 41, which is the triggering position of the rotating member 38. The rotating member 38 collides with the elastic block 41, thereby knocking the drop plate 4, causing the drop plate 4 to vibrate, and shaking off the solid matter carried in the drop plate 4, so that the solid matter falls onto the crushing roller 2 along the falling channel.

[0038] Working principle: the raw material is put into the lower hopper 1, the raw material is crushed by the crushing roller 2, the powder particles contact the rotary filter 3 along the bottom of the lower hopper 1, and are screened by the rotary filter 3, the powder particles with small particle size pass through the rotary filter 3 and enter the next process, and the solid matter with larger particle size is intercepted by the first comb teeth 33 and lifted upward along the surface of the rotary filter 3, among which part of the raw material powder particles will be deposited between the lower end of the rotary filter 3 and the bottom of the lower hopper 1, and this part of the raw material powder particles will also be lifted by the first comb teeth 33. When reaching the uppermost end, the driving gear 32 drives the driven gear 31 to rotate through meshing transmission, so that the heavy screen roller 34 rotates, and the rotation direction of the heavy screen roller 34 is opposite to that of the driving gear 32. When the heavy screen roller 34 rotates, it drives the second comb teeth 35 to move the solid matter on the rotary filter 3 along the tangential direction, and the second comb teeth The first teeth 35 are staggered with the first teeth 33, and the solids between the gaps of the two adjacent teeth of the first teeth 33 are screened out and crushed, and the solids with large particle sizes are preliminarily crushed to facilitate subsequent crushing. Then, the first teeth 33 are changed in transmission direction by the steering roller, so that the solids fall into the drop plate 4. At the same time, when the driving gear 32 rotates, the rotating member 38 is driven to rotate through the transmission belt 36. After the rotating member 38 rotates to a certain angle, it collides with the elastic block 41, which is the triggering position of the rotating member 38. The rotating member 38 collides with the elastic block 41, thereby knocking the drop plate 4, causing the drop plate 4 to vibrate, and shaking off the solids carried in the drop plate 4, so that the solids fall along the falling channel onto the crushing roller 2 and are crushed for the second time, and the process is repeated many times until all the raw material powder particles pass through the rotary filter screen 3.

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
