[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments 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 protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5 As shown, a pulp mixing device according to an embodiment of the present invention includes a fixed block 1, with a base 11 fixedly connected to the top of the fixed block 1; a first clamping block 12 and a second clamping block 13 are rotatably connected to the top of the fixed block 1, and the first clamping block 12 and the second clamping block 13 are respectively positioned corresponding to the base 11; a limiting groove 14 is formed on the top of the base 11, and a mixing cylinder 15 is provided on the top of the limiting groove 14; an open top cover 16 is provided on the top of the mixing cylinder 15, and bolts 17 are provided between the first clamping block 12, the second clamping block 13 and the open top cover 16, with multiple bolts 17 arranged in a circumferential array; a hydraulic rod 18 is rotatably connected between the first clamping block 12 and the fixed block 1, and a hydraulic rod 18 is rotatably connected between the second clamping block 13 and the fixed block 1; during operation, the hydraulic rod 18 provided between the fixed block 1 and the first clamping block 12 has its two ends rotatably connected to the fixed block 1 and the first clamping block 12 respectively, while the hydraulic rod 18 provided between the fixed block 1 and the first clamping block 12 is rotatably connected to the base 11. The hydraulic rod 18 between block 1 and the second clamping block 13 is rotatably connected to the fixed block 1 and the second clamping block 13 at both ends. When the device needs to be cleaned, the operator can first remove the bolt 17 and remove the top cover 16 from the top of the device. Then, the operator can take out the mixing drum 15 and drive the hydraulic rod 18 to retract the multiple hydraulic rods 18. As the hydraulic rods 18 retract, the first clamping block 12 and the second clamping block 13 will rotate on the top of the chassis 11 and separate. The limiting groove 14 in the fixed block 1 serves to limit the mixing drum 15. Through the above structure, the chassis 11 and the limiting groove 14 limit the mixing drum 15, the first clamping block 12 and the second clamping block 13 are clamped on the side wall of the mixing drum 15, and the top cover 16 is set to restrict the upward movement of the mixing drum 15. This makes the pulp mixing device openable, which helps to reduce the difficulty of cleaning the inside of the pulp mixing device and improve the daily cleaning efficiency of the device.

[0026] like Figures 2 to 4As shown, a motor 2 is fixedly connected to the bottom of the chassis 11, and a first gear 21 is fixedly connected to the output end of the motor 2; the first gear 21 is rotatably connected to the inside of the chassis 11; a second gear 22 meshes with the side wall of the first gear 21; a third gear 23 meshes with the side wall of the second gear 22, and the two third gears 23 are arranged correspondingly; a stirring column 24 is fixedly connected to the top of the third gear 23; clamping rods 25 are fixedly connected to the side wall of the stirring column 24, and multiple clamping rods 25 are arranged in a circumferential array; during operation, the operator can stir the slurry inside the stirring drum 15 by driving the motor 2. Whenever the motor 2 is driven, the first gear 21 fixedly connected to the output end of the motor 2 will rotate, and through its meshing relationship with the second gear 22, it will cause the second gear 22 to rotate. At this time, it is meshing with the second gear 22. The two third gears 23 will rotate synchronously. Since the stirring column 24 is fixedly connected to the third gear 23, the stirring column 24 drives the clamping rods 25 fixed to its side wall to rotate. The multiple clamping rods 25 fixed to the two stirring columns 24 are staggered. As the stirring column 24 rotates, the clamping rods 25 on the side walls of the two stirring columns 24 will rotate staggered, realizing the stirring of the pulp. And because the multiple clamping rods 25 rotate staggered, large pulp blocks will be broken under the action of the clamping rods 25. Through the above structure, the motor 2 is set to make the two stirring columns 24 and the clamping rods 25 on the stirring column 24 rotate, thereby realizing the stirring of the pulp. At the same time, the staggered arrangement of the clamping rods 25 on the two stirring columns 24 makes large pulp blocks break, which helps to enhance the stirring efficiency and stirring effect of the device.

[0027] like Figure 3 As shown, a pulp discharge valve 3 is fixedly connected to the bottom of the chassis 11; a cylinder 31 is fixedly connected to the bottom of the pulp discharge valve 3, and a piston 32 is fixedly connected to the output end of the cylinder 31; during operation, after the device has finished mixing, the operator can drive the cylinder 31 to cause the piston 32 fixed to the output end of the cylinder 31 to rise. After the piston 32 rises, it will lose contact with the top of the chassis 11, and the pulp inside the mixing drum 15 can flow into the pulp discharge valve 3 through the gap between the piston 32 and the chassis 11, and finally flow out through the pulp discharge valve 3; through the above structure, the pulp discharge valve 3 is set to guide the pulp after mixing to flow out, and the cylinder 31 and piston 32 are set to control the closing state of the pulp discharge valve 3, which improves the automation level of the pulp mixing device, helps to reduce the workload of the operator, and improves the efficiency of pulp mixing operation.

[0028] like Figure 1 , Figure 2 and 5As shown, an observation slot 4 is fixedly connected to the side wall of the mixing drum 15; a glass observation window 41 is fixedly connected to the side wall of the observation slot 4. During operation, the first clamping block 12 and the second clamping block 13 are respectively set to correspond to the size of the mixing drum 15 and the observation slot 4. When it is necessary to unfold the first clamping block 12 and the second clamping block 13, the operator can first take out the mixing drum 15 by means of the structural correspondence between the components, and then unfold the first clamping block 12 and the second clamping block 13. At the same time, the operator can observe the pulp condition by means of the glass observation window 41 fixed to the side wall of the observation slot 4. Through the above structure, the observation slot 4 and the glass observation window 41 are set to facilitate the operator to observe the pulp mixing condition, which provides convenience for the operator's mixing work and enhances the practicality and convenience of the pulp mixing device.

[0029] like Figure 5 As shown, a pressure block 5 is fixedly connected to the bottom of the perforated top cover 16, and multiple pressure blocks 5 are arranged in a circumferential array. During operation, whenever the perforated top cover 16 is connected to the first clamping block 12 and the second clamping block 13, the multiple pressure blocks 5 fixed to the bottom of the perforated top cover 16 will contact the top of the mixing cylinder 15 respectively, thereby preventing the mixing cylinder 15 from moving upward. Through the above structure, the pressure blocks 5 are set to press against the top of the mixing cylinder 15, thereby preventing the mixing cylinder 15 from moving upward during pulp mixing, improving the stability of the pulp mixing device, and helping to avoid pulp leakage.

[0030] like Figure 2 and Figure 5 As shown, a pull ring 6 is fixed to the top of the mixing drum 15, and multiple pull rings 6 are arranged in a circumferential array. During operation, whenever it is necessary to remove the mixing drum 15, the operator can use the pull rings 6 to lift the mixing drum 15 out. Through the above structure, fixing multiple pull rings 6 to the top of the mixing drum 15 makes it convenient for the operator to remove the mixing drum 15, which helps to reduce the difficulty of removing the mixing drum 15 and improves the convenience of the pulp mixing device.

[0031] like Figures 1 to 5 As shown, the chassis 11, the first clamping block 12, the second clamping block 13, the mixing cylinder 15, and the perforated top cover 16 are made of stainless steel. During operation, the use of stainless steel in the chassis 11, the first clamping block 12, the second clamping block 13, the mixing cylinder 15, and the perforated top cover 16 allows them to take advantage of the high structural strength and strong corrosion resistance of stainless steel. Through the above, the use of stainless steel in the chassis 11, the first clamping block 12, the second clamping block 13, the mixing cylinder 15, and the perforated top cover 16 enhances their structural strength and corrosion resistance, which is beneficial to extending the service life of the pulp mixing device.

[0032] During operation, the hydraulic rod 18, positioned between the fixed block 1 and the first clamping block 12, is rotatably connected to both ends of the fixed block 1 and the first clamping block 12, respectively. Similarly, the hydraulic rod 18, positioned between the fixed block 1 and the second clamping block 13, is rotatably connected to both ends of the fixed block 1 and the second clamping block 13, respectively. When cleaning the device, the operator can first remove the bolts 17 and remove the top cover 16 from the top of the device. Then, the operator can remove the stirring cylinder 15 and drive the hydraulic rods 18, causing them to retract. As the hydraulic rods 18 retract, the first clamping block 12 and the second clamping block 13 will rotate on the top of the chassis 11, separating from each other. The fixed block 1 contains a limiting groove 1. 4 serves to limit the movement of the mixing drum 15. The operator can stir the slurry inside the mixing drum 15 by driving the motor 2. Whenever the motor 2 is driven, the first gear 21 fixed to the output end of the motor 2 will rotate, and through its meshing with the second gear 22, it will cause the second gear 22 to rotate. At this time, the two third gears 23 meshing with the second gear 22 will rotate synchronously. Since the mixing column 24 is fixedly connected to the third gears 23, the mixing column 24 drives the clamping rods 25 fixed to its side wall to rotate. The multiple clamping rods 25 fixed to the two mixing columns 24 are staggered. With the rotation of the mixing column 24, the clamping rods on the side walls of the two mixing columns 24... The 25 clamping rods rotate alternately to agitate the pulp. Because the multiple clamping rods 25 rotate alternately, large pulp lumps will break under the action of the clamping rods 25. After agitation, the operator can drive the cylinder 31 to raise the piston 32 fixed to the output end of the cylinder 31. After the piston 32 rises, it will lose contact with the top of the base plate 11, and the pulp inside the agitating cylinder 15 can flow into the discharge valve 3 through the gap between the piston 32 and the base plate 11, and finally flow out through the discharge valve 3. The first clamping block 12 and the second clamping block 13 are respectively set to correspond to the dimensions of the agitating cylinder 15 and the observation slot 4. When it is necessary to unfold the first clamping block 12 and the second clamping block 13, the operator can first use the structural correspondence between the components... The mixing drum 15 is removed, and then the first clamping block 12 and the second clamping block 13 are unfolded. At the same time, the staff can observe the slurry condition through the glass observation window 41 fixed to the side wall of the observation tank 4. Whenever the top cover 16 with the opening is connected to the first clamping block 12 and the second clamping block 13, the multiple pressure blocks 5 fixed to the bottom of the top cover 16 will contact the top of the mixing drum 15 respectively, thereby preventing the mixing drum 15 from moving upward. Whenever it is necessary to remove the mixing drum 15, the staff can use the pull ring 6 to lift the mixing drum 15 out. The stainless steel chassis 11, the first clamping block 12, the second clamping block 13, the mixing drum 15, and the top cover 16 can take advantage of the high structural strength and strong corrosion resistance of stainless steel.
