Detailed Description

The structure and features of the present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that various modifications can be made to the embodiments disclosed herein, and therefore, the embodiments disclosed in the specification should not be considered as limitations of the present invention, but merely as exemplifications of the embodiments, which are intended to make the features of the present invention apparent.

As shown in fig. 1 and 2, the pulp grinder core disclosed in the present invention is composed of a stirring motor 1, a stirring rod 2, a conical conveying barrel 3, a bowl-shaped grinding tool 4 and a grinding motor 5.

Stirring rod 2 is built-in toper conveying barrel 3, and the front end shutoff of toper conveying barrel 3 has a front end motor mount pad 6, and the rotatory agitator motor 1 of drive stirring rod 2 is fixed on front end motor mount pad 6, and agitator motor 1's motor output shaft passes through the shaft coupling and links to each other with stirring rod 2, and the drive stirring rod is at 3 internal rotations of toper conveying barrel.

The rear end of the conical conveying barrel 3 is sealed and provided with a bowl-shaped grinding tool 4 and a rear end motor mounting seat 7, a grinding motor 5 for driving the bowl-shaped grinding tool 4 to rotate is fixed on the rear end motor mounting seat 7, and a motor output shaft of the grinding motor 5 is connected with the bowl-shaped grinding tool 4.

The top of the conical conveying barrel 3 is provided with a feeding port 31, shredded or crushed paper scraps or paper strips and water enter the conical conveying barrel 3 through the feeding port, the crushed paper scraps are soaked in water for a period of time and then become soft and crushed, and are stirred, rolled and pushed by the stirring rod 2 to move to the rear part of the conical conveying barrel 3, and then are pushed into the bowl-shaped grinding cutter 4 to be ground into paper pulp by the bowl-shaped grinding cutter 4.

In order to intensify the mixture of the paper scraps and the water, as shown in fig. 2, a spiral auger 21 is arranged on the stirring rod 2, and when the stirring rod 2 rotates, the spiral auger 21 pushes and rolls the mixture of the paper scraps and the water in the conical conveying barrel 3.

As shown in fig. 3A and 3B, the front section of the conical conveying barrel 3 is cylindrical, the rear section is conical, and the front section and the rear section are connected by a flange. The barrel wall of the conical conveying barrel 3 is provided with a plurality of mesh holes 32 with the diameter of 1.5-3 mm. While the stirring rod 2 pushes the mixture of shredded paper and water to tumble in the conical conveying barrel 3, the mixture of shredded paper and water is pushed to the conical rear section of the conical conveying barrel 3. Because the back section of the conical conveying barrel 3 is conical and the inner diameter is gradually reduced, the mixture of the shredded paper and the water is extruded, the volume is compressed, part of the water is extruded back to the front section of the barrel, namely the cylindrical part, part of the water is separated out from the mesh 32, and meanwhile, the mixture of the shredded paper and the water, the water of which is extruded out, is extruded into the bowl-shaped grinding cutter 4.

As shown in fig. 4A-7, the bowl-shaped grinding tool 4 is composed of a circular bowl-shaped outer knife 41 and a circular inner knife 42, the outer knife 41 and the inner knife 42 are coaxial, a circle of inclined outer saw teeth 411 is arranged on the contact surface of the outer knife 41 and the inner knife 42, correspondingly, a circle of inclined inner saw teeth 421 are also arranged on the contact surface of the inner knife 42 and the outer knife 41, and the inclination directions of the outer saw teeth 411 on the outer knife and the inner saw teeth 421 on the inner knife are opposite. When the inner blade 42 and the outer blade 41 are combined together, the inner saw teeth 421 of the inner blade 42 are staggered with the outer saw teeth 411 of the outer blade 41, and the gap between the inner blade 42 and the outer blade 41 is 1mm-1.5 mm.

After being soaked in the conical conveying barrel 3 for a period of time, the shredded paper or the paper scraps are stirred and pushed by the stirring rod 2 and move from the front section to the rear section of the conical conveying barrel 3, part of moisture in the shredded paper or the paper scraps is extruded back to the front section of the conical conveying barrel, and the shredded paper or the paper scraps with part of moisture extruded out are extruded between the inner knife 42 and the outer knife 41 of the bowl-shaped grinding cutter 4; under the driving of the grinding motor 5, the inner knife and the outer knife of the bowl-shaped grinding tool 4 move relatively, the paper and water mixture between the inner knife and the outer knife is ground, rubbed and torn, the paper is rubbed, torn and divided into paper pulp, and the ground paper pulp is extruded out from the gap between the inner knife and the outer knife, as shown in fig. 7.

In the preferred embodiment of the present invention, the inner blade 42 constituting the bowl-shaped grinding tool 4 is fixed to the rear motor mounting base 7, the outer blade 41 is sleeved on the motor output shaft of the grinding motor 5, the outer blade 41 is rotated at a high speed under the driving of the grinding motor 5, and the outer blade 41 and the inner blade 42 move relatively.

Because the outer knife 41 is rotated at a high speed under the driving of the grinding motor 5, the paper pulp extruded from the gap between the inner knife and the outer knife of the bowl-shaped grinding tool is prevented from splashing everywhere, as shown in fig. 2, the utility model discloses the outside at the bowl-shaped grinding tool 4 is covered with one and shelters from the upper cover 8.

Finally, it should be noted that: the above-mentioned embodiments are only used for illustrating the technical solution of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
